{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

You could get the whole collection as an object, rather than array like this:

async getMarker() {
    const snapshot = await firebase.firestore().collection('events').get()
    const collection = {};
    snapshot.forEach(doc => {
        collection[doc.id] = doc.data();
    });
    return collection;
}

That would give you a better representation of what's in firestore. Nothing wrong with an array, just another option.

What fixed it for me was plugging my iPhone and allowing it as a simulator destination. Doing so required my to register my iPhone in Apple Dev account and once that was done and I ran my project from Xcode on my iPhone everything fixed itself.

1. Connect your iPhone to your Mac
2. Xcode>Window>Devices & Simulators
3. Add new under Devices and make sure "show are run destination" is ticked
4. Build project and run it on your iPhone

And this:

FirebaseInstanceId.getInstance().getInstanceId().getResult().getToken()

suppose to be solution of deprecated:

FirebaseInstanceId.getInstance().getToken()

EDIT

FirebaseInstanceId.getInstance().getInstanceId().getResult().getToken() can produce exception if the task is not yet completed, so the method witch Nilesh Rathod described (with .addOnSuccessListener) is correct way to do it.

Kotlin:

FirebaseInstanceId.getInstance().instanceId.addOnSuccessListener(this) { instanceIdResult ->
        val newToken = instanceIdResult.token
        Log.e("newToken", newToken)
    }

I had the SAME issue today and it was driving me nuts!!! What I had done was upgrade to node 8.10 and upgrade my NPM to the latest I uninstalled angular CLI

npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli

I then verified my Cache from NPM if it wasn't up to date I cleaned it and ran the install again if npm version is < 5 then use npm cache clean --force

npm install -g @angular/cli@latest

and created a new project file and create a new angular project.

I was parsing JSON from a REST API call and got this error. It turns out the API had become "fussier" (eg about order of parameters etc) and so was returning malformed results. Check that you are getting what you expect :)

Note that if using the Windows Subsystem for Linux, systemd isn't supported and therefore commands like systemctl won't work:

Failed to connect to bus: No such file or directory

See Blockers for systemd? #994 on GitHub, Microsoft/WSL.

The mongo server can still be started manual via mondgod for development of course.

In my case the above suggestions did not work for me. Mine was little different scenario.

When i tried installing bundler using gem install bundler .. But i was getting

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.

then i tried using sudo gem install bundler then i was getting

ERROR:  While executing gem ... (Gem::FilePermissionError)
  You don't have write permissions for the /usr/bin directory.

then i tried with sudo gem install bundler -n /usr/local/bin ( Just /usr/bin dint work in my case ).

And then successfully installed bundler

EDIT: I use MacOS, maybe /usr/bin din't work for me for that reason (https://stackoverflow.com/a/34989655/3786657 comment )

To obtain the id of the documents in a collection, you must use snapshotChanges()

    this.shirtCollection = afs.collection<Shirt>('shirts');
    // .snapshotChanges() returns a DocumentChangeAction[], which contains
    // a lot of information about "what happened" with each change. If you want to
    // get the data and the id use the map operator.
    this.shirts = this.shirtCollection.snapshotChanges().map(actions => {
      return actions.map(a => {
        const data = a.payload.doc.data() as Shirt;
        const id = a.payload.doc.id;
        return { id, ...data };
      });
    });

Laravel Mix 4 switches from node-sass to dart-sass (which may not compile as you would expect, OR you have to deal with the issues one by one)

OR

npm install node-sass

Have you created a package.json file? Maybe run this command first again.

C:\Users\Nuwanst\Documents\NodeJS\3.chat>npm init

It creates a package.json file in your folder.

Then run,

C:\Users\Nuwanst\Documents\NodeJS\3.chat>npm install socket.io --save

The --save ensures your module is saved as a dependency in your package.json file.

Let me know if this works.

You are using both ternary operator and if condition, use any one.

By ternary operator:

.map(id => {
    return this.props.schema.collectionName.length < 0 ?
        <Expandable>
            <ObjectDisplay
                key={id}
                parentDocumentId={id}
                schema={schema[this.props.schema.collectionName]}
                value={this.props.collection.documents[id]}
            />
        </Expandable>
    :
        <h1>hejsan</h1>
}

By if condition:

.map(id => {
    if(this.props.schema.collectionName.length < 0)
        return <Expandable>
                  <ObjectDisplay
                      key={id}
                      parentDocumentId={id}
                      schema={schema[this.props.schema.collectionName]}
                      value={this.props.collection.documents[id]}
                  />
              </Expandable>
    return <h1>hejsan</h1>
}

Python comes with numerous ways of formatting strings:

New style .format(), which supports a rich formatting mini-language:

>>> temperature = 10
>>> print("the furnace is now {} degrees!".format(temperature))
the furnace is now 10 degrees!

Old style % format specifier:

>>> print("the furnace is now %d degrees!" % temperature)
the furnace is now 10 degrees!

In Py 3.6 using the new f"" format strings:

>>> print(f"the furnace is now {temperature} degrees!")
the furnace is now 10 degrees!

Or using print()s default separator:

>>> print("the furnace is now", temperature, "degrees!")
the furnace is now 10 degrees!

And least effectively, construct a new string by casting it to a str() and concatenating:

>>> print("the furnace is now " + str(temperature) + " degrees!")
the furnace is now 10 degrees!

Or join()ing it:

>>> print(' '.join(["the furnace is now", str(temperature), "degrees!"]))
the furnace is now 10 degrees!

Warning! This package referenced a Flutter repository via the .packages file that is no longer available. The repository from which the 'flutter' tool is currently executing will be used instead.
running Flutter tool: /opt/flutter previous reference : /Users/Shared/Library/flutter This can happen if you deleted or moved your copy of the Flutter repository, or if it was on a volume that is no longer mounted or has been mounted at a different location. Please check your system path to verify that you are running the expected version (run 'flutter --version' to see which flutter is on your path).

Checking the output of the flutter packages get reveals that the reason in my case was due to moving the flutter sdk.

I had a similar problem when I rearranged the folder structure of a project. I tried all the hints given in this thread but none of them worked. After checking further I discovered that I forgot to copy an important hidden file over to the new directory. That was

.angular-cli.json

from the root directory of the @angular/cli project. After I copied that file over all was running as expected.

you can try to this , then you get a bitmap of selected image and then you can easily find it's native path from Device Default Gallery.

Bitmap roughBitmap= null;
    try {
    // Works with content://, file://, or android.resource:// URIs
    InputStream inputStream =
    getContentResolver().openInputStream(uri);
    roughBitmap= BitmapFactory.decodeStream(inputStream);

    // calc exact destination size
    Matrix m = new Matrix();
    RectF inRect = new RectF(0, 0, roughBitmap.Width, roughBitmap.Height);
    RectF outRect = new RectF(0, 0, dstWidth, dstHeight);
    m.SetRectToRect(inRect, outRect, Matrix.ScaleToFit.Center);
    float[] values = new float[9];
    m.GetValues(values);


    // resize bitmap if needed
    Bitmap resizedBitmap = Bitmap.CreateScaledBitmap(roughBitmap, (int) (roughBitmap.Width * values[0]), (int) (roughBitmap.Height * values[4]), true);

    string name = "IMG_" + new Java.Text.SimpleDateFormat("yyyyMMdd_HHmmss").Format(new Java.Util.Date()) + ".png";
    var sdCardPath= Environment.GetExternalStoragePublicDirectory("DCIM").AbsolutePath;
    Java.IO.File file = new Java.IO.File(sdCardPath);
    if (!file.Exists())
    {
        file.Mkdir();
    }
    var filePath = System.IO.Path.Combine(sdCardPath, name);
    } catch (FileNotFoundException e) {
    // Inform the user that things have gone horribly wrong
    }

• groupByKey() is just to group your dataset based on a key. It will result in data shuffling when RDD is not already partitioned.
• reduceByKey() is something like grouping + aggregation. We can say reduceBykey() equvelent to dataset.group(...).reduce(...). It will shuffle less data unlike groupByKey().
• aggregateByKey() is logically same as reduceByKey() but it lets you return result in different type. In another words, it lets you have a input as type x and aggregate result as type y. For example (1,2),(1,4) as input and (1,"six") as output. It also takes zero-value that will be applied at the beginning of each key.

Note : One similarity is they all are wide operations.

I got the errors to go away by installing the Windows Universal CRT SDK component, which adds support for legacy Windows SDKs. You can install this using the Visual Studio Installer:

If the problem still persists, you should change the Target SDK in the Visual Studio Project : check whether the Windows SDK version is 10.0.15063.0.

In : Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0.

Then errno.h and other standard files will be found and it will compile.

changing 'Citable docs per Capita' to numeric before correlation will solve the problem.

    Top15['Citable docs per Capita'] = pd.to_numeric(Top15['Citable docs per Capita'])
    data = Top15[['Citable docs per Capita','Energy Supply per Capita']]
    correlation = data.corr(method='pearson')

I think you just need to create your volume outside docker first with a docker create -v /location --name and then reuse it.

And by the time I used to use docker a lot, it wasn't possible to use a static docker volume with dockerfile definition so my suggestion is to try the command line (eventually with a script ) .

To be short, use:

write-output "your text" | out-file -append -encoding utf8 "filename"

Using extract-css-chunks-webpack-plugin and css-loader loader work for me, see below:

webpack.config.js Import extract-css-chunks-webpack-plugin

const ExtractCssChunks = require('extract-css-chunks-webpack-plugin');

webpack.config.js Add the css rule, Extract css Chunks first then the css loader css-loader will embed them into the html document, ensure css-loader and extract-css-chunks-webpack-plugin are in the package.json dev dependencies

rules: [
      {
        test: /\.css$/,
        use: [
          {
            loader: ExtractCssChunks.loader,
          },
          'css-loader',
        ],
      }
]

webpack.config.js Make instance of the plugin

plugins: [
    new ExtractCssChunks({
      // Options similar to the same options in webpackOptions.output
      // both options are optional
      filename: '[name].css',
      chunkFilename: '[id].css'
    })
  ]

And now importing css is possible And now in a tsx file like index.tsx i can use import like this import './Tree.css' where Tree.css contains css rules like

body {
    background: red;
}

My app is using typescript and this works for me, check my repo for the source : https://github.com/nickjohngray/staticbackeditor

Check what git remote -v returns: the account used to push to an http url is usually embedded into the remote url itself.

https://[email protected]/...

If that is the case, put an url which will force Git to ask for the account to use when pushing:

git remote set-url origin https://github.com/<user>/<repo>

Or one to use the Fre1234 account:

git remote set-url origin https://[email protected]/<user>/<repo>

Also check if you installed your Git For Windows with or without a credential helper as in this question.

The OP Fre1234 adds in the comments:

I finally found the solution.
Go to: Control Panel -> User Accounts -> Manage your credentials -> Windows Credentials

Under Generic Credentials there are some credentials related to Github,
Click on them and click "Remove".

That is because the default installation for Git for Windows set a Git-Credential-Manager-for-Windows.
See git config --global credential.helper output (it should be manager)

img = cv2.imread("/x2.jpeg")

image = cv2.resize(img, (1800, 1800))

alpha=1.5
beta=20

new_image=cv2.addWeighted(image,alpha,np.zeros(image.shape, image.dtype),0,beta)

cv2.imshow("new",new_image)
cv2.waitKey(0)
cv2.destroyAllWindows()

Just change the CSV file name. Once I changed it for me, it worked fine. Previously I gave data.csv then I changed it to CNC_1.csv.

To make it work without modifying your scripts:

I found a solution here: http://wahlnetwork.com/2015/11/17/solving-the-first-launch-configuration-error-with-powershells-invoke-webrequest-cmdlet/

The error is probably coming up because IE has not yet been launched for the first time, bringing up the window below. Launch it and get through that screen, and then the error message will not come up any more. No need to modify any scripts.

Node.JS does not fully support ES6 currently, so you can either use asyncawait module or transpile it using Bable.

install

npm install --save asyncawait

helloz.js

var async = require('asyncawait/async');
var await = require('asyncawait/await');

(async (function testingAsyncAwait() {
    await (console.log("Print me!"));
}))();

You can just put r in front of the string with your actual path, which denotes a raw string. For example:

data = open(r"C:\Users\miche\Documents\school\jaar2\MIK\2.6\vektis_agb_zorgverlener")

From your log its clear that numpy package is missing. As mention in the PyPI package:

The SciPy library depends on NumPy, which provides convenient and fast N-dimensional array manipulation.

So, try installing numpy package for python as you did with scipy.

Since your task might contain asynchronous code you have to signal gulp when your task has finished executing (= "async completion").

In Gulp 3.x you could get away without doing this. If you didn't explicitly signal async completion gulp would just assume that your task is synchronous and that it is finished as soon as your task function returns. Gulp 4.x is stricter in this regard. You have to explicitly signal task completion.

You can do that in six ways:

1. Return a Stream

This is not really an option if you're only trying to print something, but it's probably the most frequently used async completion mechanism since you're usually working with gulp streams. Here's a (rather contrived) example demonstrating it for your use case:

var print = require('gulp-print');

gulp.task('message', function() {
  return gulp.src('package.json')
    .pipe(print(function() { return 'HTTP Server Started'; }));
});

The important part here is the return statement. If you don't return the stream, gulp can't determine when the stream has finished.

2. Return a Promise

This is a much more fitting mechanism for your use case. Note that most of the time you won't have to create the Promise object yourself, it will usually be provided by a package (e.g. the frequently used del package returns a Promise).

gulp.task('message', function() { 
  return new Promise(function(resolve, reject) {
    console.log("HTTP Server Started");
    resolve();
  });
});

Using async/await syntax this can be simplified even further. All functions marked async implicitly return a Promise so the following works too (if your node.js version supports it):

gulp.task('message', async function() {
  console.log("HTTP Server Started");
});

3. Call the callback function

This is probably the easiest way for your use case: gulp automatically passes a callback function to your task as its first argument. Just call that function when you're done:

gulp.task('message', function(done) {
  console.log("HTTP Server Started");
  done();
});

4. Return a child process

This is mostly useful if you have to invoke a command line tool directly because there's no node.js wrapper available. It works for your use case but obviously I wouldn't recommend it (especially since it's not very portable):

var spawn = require('child_process').spawn;

gulp.task('message', function() {
  return spawn('echo', ['HTTP', 'Server', 'Started'], { stdio: 'inherit' });
});

5. Return a RxJS Observable.

I've never used this mechanism, but if you're using RxJS it might be useful. It's kind of overkill if you just want to print something:

var of = require('rxjs').of;

gulp.task('message', function() {
  var o = of('HTTP Server Started');
  o.subscribe(function(msg) { console.log(msg); });
  return o;
});

6. Return an EventEmitter

Like the previous one I'm including this for completeness sake, but it's not really something you're going to use unless you're already using an EventEmitter for some reason.

gulp.task('message3', function() {
  var e = new EventEmitter();
  e.on('msg', function(msg) { console.log(msg); });
  setTimeout(() => { e.emit('msg', 'HTTP Server Started'); e.emit('finish'); });
  return e;
});

EDIT

I am seeing a bit of activity on my answer so I decided to improve it a bit for those with this issue still

There are basically three main methods of achieving administrator execution privileges on Windows.

1. Running as admin from cmd.exe
2. Creating a shortcut to execute the file with elevated privileges
3. Changing the permissions on the python executable (Not recommended)

1) Running cmd.exe as and admin

Since in Windows there is no sudo command you have to run the terminal (cmd.exe) as an administrator to achieve to level of permissions equivalent to sudo. You can do this two ways:

1. Manually

   • Find cmd.exe in C:\Windows\system32
   • Right-click on it
   • Select Run as Administrator
   • It will then open the command prompt in the directory C:\Windows\system32
   • Travel to your project directory
   • Run your program

2. Via key shortcuts

   • Press the windows key (between alt and ctrl usually) + X.
   • A small pop-up list containing various administrator tasks will appear.
   • Select Command Prompt (Admin)
   • Travel to your project directory
   • Run your program

By doing that you are running as Admin so this problem should not persist

2) Creating shortcut with elevated privileges

1. Create a shortcut for python.exe
2. Righ-click the shortcut and select Properties
3. Change the shortcut target into something like "C:\path_to\python.exe" C:\path_to\your_script.py"
4. Click "advanced" in the property panel of the shortcut, and click the option "run as administrator"

Answer contributed by delphifirst in this question

3) Changing the permissions on the python executable (Not recommended)

This is a possibility but I highly discourage you from doing so.

It just involves finding the python executable and setting it to run as administrator every time. Can and probably will cause problems with things like file creation (they will be admin only) or possibly modules that require NOT being an admin to run.

The two main differences are:

• when you capture even a single argument, you are able to make much more elaborate tests on this argument, and with more obvious code;
• an ArgumentCaptor can capture more than once.

To illustrate the latter, say you have:

final ArgumentCaptor<Foo> captor = ArgumentCaptor.forClass(Foo.class);

verify(x, times(4)).someMethod(captor.capture()); // for instance

Then the captor will be able to give you access to all 4 arguments, which you can then perform assertions on separately.

This or any number of arguments in fact, since a VerificationMode is not limited to a fixed number of invocations; in any event, the captor will give you access to all of them, if you wish.

This also has the benefit that such tests are (imho) much easier to write than having to implement your own ArgumentMatchers -- particularly if you combine mockito with assertj.

Oh, and please consider using TestNG instead of JUnit.

I changed the target=android-26 to target=android-23

project.properties

this works great for me.

If you don't want to reboot your can, a solution is to manually attach the debugger. In my case the application is launched but visual studio fails to connect to the iis. In Visual Studio 2019: Debug -> Attach to process -> filter by iis and select iisexpress.exe

@bninopaul 's answer is not completely for beginners

here is the code you can "copy and run"

import seaborn as sn
import pandas as pd
import matplotlib.pyplot as plt

array = [[13,1,1,0,2,0],
         [3,9,6,0,1,0],
         [0,0,16,2,0,0],
         [0,0,0,13,0,0],
         [0,0,0,0,15,0],
         [0,0,1,0,0,15]]

df_cm = pd.DataFrame(array, range(6), range(6))
# plt.figure(figsize=(10,7))
sn.set(font_scale=1.4) # for label size
sn.heatmap(df_cm, annot=True, annot_kws={"size": 16}) # font size

plt.show()

OSX Sierra, Python 2.7, Graphviz 2.38

Using pip install graphviz and conda install graphviz BOTH resolves the problem.

pip only gets path problem same as yours and conda only gets import error.

For fixing:

No matching client found for package name 'com.example.exampleapp:

You should get a valid google-service.json file for your package from here

For fixing:

Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 8.3.0.:

You should move apply plugin: 'com.google.gms.google-services' to the end of your app gradle.build file. Something like this:

dependencies {
    ...
}
apply plugin: 'com.google.gms.google-services'

To change the font globally for ggplot2 plots.

theme_set(theme_gray(base_size = 20, base_family = 'Font Name' ))

I also had this error I took this part of code from .csproj file:

 <Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
      <PropertyGroup>
        <ErrorText>This project references NuGet package(s) that are missing on this computer. Enable NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
      </PropertyGroup>

My solution was to use global session helper: session()

Its functionality is a little bit harder than $request->session().

writing:

session(['key'=>'value']);

pushing:

session()->push('key', $notification);

retrieving:

session('key');

This worked me, put /// <reference path="../node_modules/angular2/typings/browser.d.ts" /> at the top of bootstraping file.

For example:-

In boot.ts

/// <reference path="../node_modules/angular2/typings/browser.d.ts" />
import {bootstrap} from 'angular2/platform/browser'
import  {AppComponent} from './app.component'

bootstrap(AppComponent);

Note:- Make sure you have mention the correct reference path.

If you go one level up in running the script in the command line of your bash shell, the issue will be resolved. To do this, use cd .. command to change the working directory in which your script will be running. The result should look like this:

[username@localhost myProgram]$

rather than this:

[username@localhost app]$

Once you are there, instead of running the script in the following format:

python3 mymodule.py

Change it to this:

python3 app/mymodule.py

This process can be repeated once again one level up depending on the structure of your Tree diagram. Please also include the compilation command line that is giving you that mentioned error message.

The -o option didn't work for me because the artifact is still in development and not yet uploaded and maven (3.5.x) still tries to download it from the remote repository because it's the first time, according to the error I get.

However this fixed it for me: https://maven.apache.org/general.html#importing-jars

After this manual install there's no need to use the offline option either.

UPDATE

I've just rebuilt the dependency and I had to re-import it: the regular mvn clean install was not sufficient for me

First, I use:

 mysql -u root -p

Giving my current password for the 'root'. Next:

mysql> ALTER USER `root`@`localhost` IDENTIFIED BY 'new_password',
       `root`@`localhost` PASSWORD EXPIRE NEVER;

Change 'new_password' to a new password for the user 'root'.
It solved my problem.

"scripts": {
  "prestart": "npm install",
  "start": "http-server -a localhost -p 8000 -c-1"
}

add this code snippet in your package.json, depending on your own configuration.

You need to restart mongo to solve the topology error, then just change some options of mongoose or mongoclient to overcome this problem:

var mongoOptions = {
    useMongoClient: true,
    keepAlive: 1,
    connectTimeoutMS: 30000,
    reconnectTries: Number.MAX_VALUE,
    reconnectInterval: 5000,
    useNewUrlParser: true
}

mongoose.connect(mongoDevString,mongoOptions);

Your library was compiled without bitcode, but the bitcode option is enabled in your project settings. Say NO to Enable Bitcode in your target Build Settings and the Library Build Settings to remove the warnings.

For those wondering if enabling bitcode is required:

For iOS apps, bitcode is the default, but optional. For watchOS and tvOS apps, bitcode is required. If you provide bitcode, all apps and frameworks in the app bundle (all targets in the project) need to include bitcode.

This works in Mac as well you can use

df= pd.read_csv('Region_count.csv', encoding ='latin1')

I resolve this problem with following function. I use Visual Studio 2019.

FILE* __cdecl __iob_func(void)
{
    FILE _iob[] = { *stdin, *stdout, *stderr };
    return _iob;
}

because stdin Macro defined function call, "*stdin" expression is cannot used global array initializer. But local array initialier is possible. sorry, I am poor at english.

Why don't you simply move the code you have in the ApiController calls - DocumentsController to a class that you can call from both your HomeController and DocumentController. Pull this out into a class you call from both controllers. This stuff in your question:

// All code to find the files are here and is working perfectly...

It doesn't make sense to call a API Controller from another controller on the same website.

This will also simplify the code when you come back to it in the future you will have one common class for finding the files and doing that logic there...

Delete .android folder cache files, Also delete the build folder manually from a directory and open android studio and run again.

$filterQuery = $this->queryFactory->create(QueryInterface::TYPE_BOOL, ['must' => $queries,'should'=>$queriesGeo]);

In must you need to add the query condition array which you want to work with AND and in should you need to add the query condition which you want to work with OR.

You can check this: https://github.com/Smile-SA/elasticsuite/issues/972

I wanted to add how I fixed this issue, as I had to do a bit of mix and match from a few different solutions. For reference this is for a Windows 10 PC, nodemon had worked perfectly for months and then suddenly the command was not found unless run locally with npx. Here were my steps -

1. Check to see if it is installed globally by running npm list -g --depth=0, in my case it was installed, so to start fresh...
2. I ran npm uninstall -g nodemon
3. Next, I reinstalled using npm install -g --force nodemon --save-dev (it might be recommended to try running npm install -g nodemon --save-dev first, go through the rest of the steps, and if it doesn't work go through steps 2 & 3 again using --force).
4. Then I checked where my npm folder was located with the command npm config get prefix, which in my case was located at C:\Users\username\AppData\Roaming\npm
5. I modified my PATH variable to add both that file path and a second entry with \bin appended to it (I am not sure which one is actually needed as some people have needed just the root npm folder and others have needed bin, it was easy enough to simply add both)
6. Finally, I followed similar directions to what Natesh recommended on this entry, however, with Windows, the .bashrc file doesn't automatically exist, so you need to create one in your ~ directory. I also needed to slightly alter how the export was written to be export PATH=%PATH%;C:\Users\username\AppData\Roaming\npm; (Obviously replace "username" with whatever your username is, or whatever the file path was that was retrieved in step 4)

I hope this helps anyone who has been struggling with this issue for as long as I have!

Try go to Tools->Options->Debugging->Symbols and select checkbox "Microsoft Symbol Servers", Visual Studio will download PDBs automatically.

PDB is a debug information file used by Visual Studio. These are system DLLs, which you don't have debug symbols for.[...]

See Cannot find or open the PDB file in Visual Studio C++ 2010

The easiest way to convert back it in PowerShell

[System.Net.NetworkCredential]::new("", $SecurePassword).Password

You can also convert by creating a dictionary of elements and then directly converting to a data frame:

import xml.etree.ElementTree as ET
import pandas as pd

# Contents of test.xml
# <?xml version="1.0" encoding="utf-8"?> <tags>   <row Id="1" TagName="bayesian" Count="4699" ExcerptPostId="20258" WikiPostId="20257" />   <row Id="2" TagName="prior" Count="598" ExcerptPostId="62158" WikiPostId="62157" />   <row Id="3" TagName="elicitation" Count="10" />   <row Id="5" TagName="open-source" Count="16" /> </tags>

root = ET.parse('test.xml').getroot()

tags = {"tags":[]}
for elem in root:
    tag = {}
    tag["Id"] = elem.attrib['Id']
    tag["TagName"] = elem.attrib['TagName']
    tag["Count"] = elem.attrib['Count']
    tags["tags"]. append(tag)

df_users = pd.DataFrame(tags["tags"])
df_users.head()

The correct sizes are as following:

1)58x58

2)80x80

3)120x120

4)180x180

I think you can use db.collection.distinct(fields,query)

You will be able to get the distinct values in your case for NetworkID.

It should be something like this :

Db.collection.distinct('NetworkID')

MongoDB shell version v4.2.6
Node v14.2.0

Assuming you have a Tour Model: tourModel.js

const mongoose = require('mongoose');

const tourSchema = new mongoose.Schema({
  name: {
    type: String,
    required: [true, 'A tour must have a name'],
    unique: true,
    trim: true,
  },
  createdAt: {
    type: Date,
    default: Date.now(),
  },
});
const Tour = mongoose.model('Tour', tourSchema);

module.exports = Tour;

Now you want to delete all tours at once from your MongoDB, I also providing connection code to connect with the remote cluster. I used deleteMany(), if you do not pass any args to deleteMany(), then it will delete all the documents in Tour collection.

const mongoose = require('mongoose');
const Tour = require('./../../models/tourModel');
const conStr = 'mongodb+srv://lord:<PASSWORD>@cluster0-eeev8.mongodb.net/tour-guide?retryWrites=true&w=majority';
const DB = conStr.replace('<PASSWORD>','ADUSsaZEKESKZX');
mongoose.connect(DB, {
    useNewUrlParser: true,
    useCreateIndex: true,
    useFindAndModify: false,
    useUnifiedTopology: true,
  })
  .then((con) => {
    console.log(`DB connection successful ${con.path}`);
  });

const deleteAllData = async () => {
  try {
    await Tour.deleteMany();
    console.log('All Data successfully deleted');
  } catch (err) {
    console.log(err);
  }
};

Whilst this an old question, I ran into this problem myself recently and some of the answers here are now deprecated (as the comments point out). So for the benefit of others who may have stumbled here:

A term query can be used to find the exact term specified in the reverse index:

{
  "query": {
   "term" : { "tags" : "a" }
} 

From the documenation https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-term-query.html

Alternatively you can use a terms query, which will match all documents with any of the items specified in the given array:

{
  "query": {
   "terms" : { "tags" : ["a", "c"]}
} 

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-terms-query.html

One gotcha to be aware of (which caught me out) - how you define the document also makes a difference. If the field you're searching in has been indexed as a text type then Elasticsearch will perform a full text search (i.e using an analyzed string).

If you've indexed the field as a keyword then a keyword search using a 'non-analyzed' string is performed. This can have a massive practical impact as Analyzed strings are pre-processed (lowercased, punctuation dropped etc.) See (https://www.elastic.co/guide/en/elasticsearch/guide/master/term-vs-full-text.html)

To avoid these issues, the string field has split into two new types: text, which should be used for full-text search, and keyword, which should be used for keyword search. (https://www.elastic.co/blog/strings-are-dead-long-live-strings)

You have to run pip.exe from the command prompt on my computer. I type C:/Python27/Scripts/pip2.exe install numpy

As a rule of thumb, you should build a fat JAR using Maven (a JAR that contains both your code and all dependencies).

Then you can write a Dockerfile that matches your requirements (if you can build a fat JAR you would only need a base os, like CentOS, and the JVM).

This is what I use for a Scala app (which is Java-based).

FROM centos:centos7

# Prerequisites.

RUN yum -y update
RUN yum -y install wget tar

# Oracle Java 7

WORKDIR /opt

RUN wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/7u71-b14/server-jre-7u71-linux-x64.tar.gz
RUN tar xzf server-jre-7u71-linux-x64.tar.gz
RUN rm -rf server-jre-7u71-linux-x64.tar.gz
RUN alternatives --install /usr/bin/java java /opt/jdk1.7.0_71/bin/java 1

# App

USER daemon

# This copies to local fat jar inside the image
ADD /local/path/to/packaged/app/appname.jar /app/appname.jar

# What to run when the container starts
ENTRYPOINT [ "java", "-jar", "/app/appname.jar" ]

# Ports used by the app
EXPOSE 5000

This creates a CentOS-based image with Java7. When started, it will execute your app jar.

The best way to deploy it is via the Docker Registry, it's like a Github for Docker images.

You can build an image like this:

# current dir must contain the Dockerfile
docker build -t username/projectname:tagname .

You can then push an image in this way:

docker push username/projectname # this pushes all tags

Once the image is on the Docker Registry, you can pull it from anywhere in the world and run it.

See Docker User Guide for more informations.

Something to keep in mind:

You could also pull your repository inside an image and build the jar as part of the container execution, but it's not a good approach, as the code could change and you might end up using a different version of the app without notice.

Building a fat jar removes this issue.

Simple and dynamic solution (Swift 5):

extension FileManager {

  class func directoryUrl() -> URL? {
      let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
      return paths.first
  }

  class func allRecordedData() -> [URL]? {
     if let documentsUrl = FileManager.directoryUrl() {
        do {
            let directoryContents = try FileManager.default.contentsOfDirectory(at: documentsUrl, includingPropertiesForKeys: nil)
            return directoryContents.filter{ $0.pathExtension == "m4a" }
        } catch {
            return nil
        }
     }
     return nil
  }}

For me, the reason is that the gradle.zip IDE downloaded is broken (I cannot uncompress it manually), and following steps help.

1. gradle sync, and it says could not install from ${link}, ${gralde.zip} ...
2. download from ${link} manually
3. go to the ${gradle.zip}'s location
4. replace the ${gradle.zip} with the one downloaded, remove the .lck file on the same path.
5. gradle sync.

Note:

• ${link} is something like https://services.gradle.org/distributions/gradle-4.6-all.zip
• ${gradle.zip} looks like ~/.gradle/wrapper/dists/gradle-${version}-all/${a-serial-string}/gradle-${version}-all.zip

I had this error and solution help which was posted by Anirudh. I built a template for express routing and forgot about this nuance - glad it was an easy fix.

I wanted to give a little clarification to his answer on where to put this code by explaining my file structure.

My typical file structure is as follows:

/lib

/routes

---index.js (controls the main navigation)

/page-one



/page-two



     ---index.js

(each file [in my case the index.js within page-two, although page-one would have an index.js too]- for each page - that uses app.METHOD or router.METHOD needs to have module.exports = router; at the end)

If someone wants I will post a link to github template that implements express routing using best practices. let me know

Thanks Anirudh!!! for the great answer.

At first I was stuck trying to figure out out to "insert" the Guest Additions CD image in Windows because I presumed it was a separate download that I would have to mount or somehow attach to the virtual CD drive. But just going through the Mac VirtualBox Devices menu and picking "Insert Guest Additions CD Image..." seemed to do the trick. Nothing to mount, nothing to "insert".

Elsewhere I found that the Guest Additions update was part of the update package, so I guess the new VB found the new GA CD automatically when Windows went looking. I wish I had known that to start.

Also, it appears that when I installed the Guest Additions on my Linked Base machine, it propagated to the other machines that were based on it. Sweet. Only one installation for multiple "machines".

I still haven't found that documented, but it appears to be the case (probably I'm not looking for the right explanation terms because I don't already know the explanation). How that works should probably be a different thread.

I'm answering only the part of the question about zbar installation.

I spent nearly half an hour a few hours to make it work on Windows + Python 2.7 64-bit, so here are additional notes to the accepted answer:

• Download https://github.com/NaturalHistoryMuseum/ZBarWin64/releases/download/v0.10/zbar-0.10-cp27-none-win_amd64.whl

• Install it with pip install zbar-0.10-cp27-none-win_amd64.whl

• If Python reports an ImportError: DLL load failed: The specified module could not be found. when doing import zbar, then you will just need to install the Visual C++ Redistributable Packages for VS 2013 (I spent a lot of time here, trying to recompile unsuccessfully...)

• Required too: libzbar64-0.dll must be in a folder which is in the PATH. In my case I copied it to "C:\Python27\libzbar64-0.dll" (which is in the PATH). If it still does not work, add this:

  import os
  os.environ['PATH'] += ';C:\\Python27' 
  import zbar
  

PS: Making it work with Python 3.x is even more difficult: Compile zbar for Python 3.x.

PS2: I just tested pyzbar with pip install pyzbar and it's MUCH easier, it works out-of-the-box (the only thing is you need to have VC Redist 2013 files installed). It is also recommended to use this library in this pyimagesearch.com article.

in spring boot :

1) if your file is ouside jar you can use :        

@Autowired
private ResourceLoader resourceLoader;

**.resource(resourceLoader.getResource("file:/path_to_your_file"))**

2) if your file is inside resources of jar you can `enter code here`use :

**.resource(new ClassPathResource("file_name"))**

I'm using Django CMS 3.4 with Django 1.8. I stepped through the root cause in the Django CMS code. Root cause is the Django CMS is not changing directory to the directory with file containing the SQLite3 database before making database calls. The error message is spurious. The underlying problem is that a SQLite database call is made in the wrong directory.

The workaround is to ensure all your Django applications change directory back to the Django Project root directory when changing to working directories.

I think this is the "set it and forget it" solution:

options(repos='http://cran.rstudio.com/')

Note that this isn't https. I was on a Linux machine, ssh'ing in. If I used https, it didn't work.

Not sure this answers the question but I believe it's worth mentioning here. There is one more way for selecting single field (and not multiple) using db.collection_name.distinct();

e.g.,db.student.distinct('roll',{});

Or, 2nd way: Using db.collection_name.find().forEach(); (multiple fields can be selected here by concatenation)

e.g., db.collection_name.find().forEach(function(c1){print(c1.roll);});

This issue can be resolved by adding TestNG.class package to OnlineStore package as below

1. Step 1: Build Path > Configure Build Path > Java Build Path > Select "Project" tab
2. Step 2: Click "add" button and select the project with contains the TestNG source.
3. Step 3 select TestNG.xml run as "TestNG Suite"

To add to the other answers, instead of assigning to a differently named variable inside of an if condition:

var a: Int? = 5

if let b = a {
   // do something
}

you can reuse the same variable name like this:

var a: Int? = 5

if let a = a {
    // do something
}

This might help you avoid running out of creative variable names...

This takes advantage of variable shadowing that is supported in Swift.

Your problems have nothing to do with POST/GET but only with how you specify parameters in RouteAttribute. To ensure this, I added support for both verbs in my samples.

Let's go back to two very simple working examples.

[Route("api/deliveryitems/{anyString}")]
[HttpGet, HttpPost]
public HttpResponseMessage GetDeliveryItemsOne(string anyString)
{
    return Request.CreateResponse<string>(HttpStatusCode.OK, anyString);
}

And

[Route("api/deliveryitems")]
[HttpGet, HttpPost]
public HttpResponseMessage GetDeliveryItemsTwo(string anyString = "default")
{
    return Request.CreateResponse<string>(HttpStatusCode.OK, anyString);
}

The first sample says that the "anyString" is a path segment parameter (part of the URL).

First sample example URL is:

• localhost:xxx/api/deliveryItems/dkjd;dslkf;dfk;kkklm;oeop
  • returns "dkjd;dslkf;dfk;kkklm;oeop"

The second sample says that the "anyString" is a query string parameter (optional here since a default value has been provided, but you can make it non-optional by simply removing the default value).

Second sample examples URL are:

• localhost:xxx/api/deliveryItems?anyString=dkjd;dslkf;dfk;kkklm;oeop
  • returns "dkjd;dslkf;dfk;kkklm;oeop"
• localhost:xxx/api/deliveryItems
  • returns "default"

Of course, you can make it even more complex, like with this third sample:

[Route("api/deliveryitems")]
[HttpGet, HttpPost]
public HttpResponseMessage GetDeliveryItemsThree(string anyString, string anotherString = "anotherDefault")
{
    return Request.CreateResponse<string>(HttpStatusCode.OK, anyString + "||" + anotherString);
}

Third sample examples URL are:

• localhost:xxx/api/deliveryItems?anyString=dkjd;dslkf;dfk;kkklm;oeop
  • returns "dkjd;dslkf;dfk;kkklm;oeop||anotherDefault"
• localhost:xxx/api/deliveryItems
  • returns "No HTTP resource was found that matches the request URI ..." (parameter anyString is mandatory)
• localhost:xxx/api/deliveryItems?anotherString=bluberb&anyString=dkjd;dslkf;dfk;kkklm;oeop
  • returns "dkjd;dslkf;dfk;kkklm;oeop||bluberb"
  • note that the parameters have been reversed, which does not matter, this is not possible with "URL-style" of first example

When should you use path segment or query parameters? Some advice has already been given here: REST API Best practices: Where to put parameters?

Put this in /etc/init (Use /etc/systemd in Ubuntu 15.x)

mystartupscript.conf

start on runlevel [2345]
stop on runlevel [!2345]

exec /path/to/script.py

By placing this conf file there you hook into ubuntu's upstart service that runs services on startup.

manual starting/stopping is done with sudo service mystartupscript start and sudo service mystartupscript stop

I’ve used below code to fetch JSON from FAQ-data.json file present in project directory .

I’m implementing in Xcode 7.3 using Swift.

     func fetchJSONContent() {
            if let path = NSBundle.mainBundle().pathForResource("FAQ-data", ofType: "json") {

                if let jsonData = NSData(contentsOfFile: path) {
                    do {
                        if let jsonResult: NSDictionary = try NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary {

                            if let responseParameter : NSDictionary = jsonResult["responseParameter"] as? NSDictionary {

                                if let response : NSArray = responseParameter["FAQ"] as? NSArray {
                                    responseFAQ = response
                                    print("response FAQ : \(response)")
                                }
                            }
                        }
                    }
                    catch { print("Error while parsing: \(error)") }
                }
            }
        }

override func viewWillAppear(animated: Bool) {
        fetchFAQContent()
    }

Structure of JSON file :

{
    "status": "00",
    "msg": "FAQ List ",
    "responseParameter": {
        "FAQ": [
            {                
                "question": “Question No.1 here”,
                "answer": “Answer goes here”,  
                "id": 1
            },
            {                
                "question": “Question No.2 here”,
                "answer": “Answer goes here”,
                "id": 2
            }
            . . .
        ]
    }
}

To Convert file path in String to NSURL, observe the following code

var filePathUrl = NSURL.fileURLWithPath(path)

works at Swift 5

    do {
        let documentDirectory = try FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
        let fileUrl = documentDirectory.appendingPathComponent("userInfo").appendingPathExtension("sqlite3")
        if FileManager.default.fileExists(atPath: fileUrl.path) {
            print("FILE AVAILABLE")
        } else {
            print("FILE NOT AVAILABLE")
        }
    } catch {
        print(error)
    }

where "userInfo" - file's name, and "sqlite3" - file's extension

For everyone who looks example that works with Swift 2.2, Abizern code with modern do try catch handle of error

func databaseURL() -> NSURL? {

    let fileManager = NSFileManager.defaultManager()

    let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)

    if let documentDirectory:NSURL = urls.first { // No use of as? NSURL because let urls returns array of NSURL
        // This is where the database should be in the documents directory
        let finalDatabaseURL = documentDirectory.URLByAppendingPathComponent("OurFile.plist")

        if finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) {
            // The file already exists, so just return the URL
            return finalDatabaseURL
        } else {
            // Copy the initial file from the application bundle to the documents directory
            if let bundleURL = NSBundle.mainBundle().URLForResource("OurFile", withExtension: "plist") {

                do {
                    try fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL)
                } catch let error as NSError  {// Handle the error
                    print("Couldn't copy file to final location! Error:\(error.localisedDescription)")
                }

            } else {
                print("Couldn't find initial database in the bundle!")
            }
        }
    } else {
        print("Couldn't get documents directory!")
    }

    return nil
}

Update I've missed that new swift 2.0 have guard(Ruby unless analog), so with guard it is much shorter and more readable

func databaseURL() -> NSURL? {

let fileManager = NSFileManager.defaultManager()
let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)

// If array of path is empty the document folder not found
guard urls.count != 0 else {
    return nil
}

let finalDatabaseURL = urls.first!.URLByAppendingPathComponent("OurFile.plist")
// Check if file reachable, and if reacheble just return path
guard finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) else {
    // Check if file is exists in bundle folder
    if let bundleURL = NSBundle.mainBundle().URLForResource("OurFile", withExtension: "plist") {
        // if exist we will copy it
        do {
            try fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL)
        } catch let error as NSError { // Handle the error
            print("File copy failed! Error:\(error.localizedDescription)")
        }
    } else {
        print("Our file not exist in bundle folder")
        return nil
    }
    return finalDatabaseURL
}
return finalDatabaseURL 
}

You can replace the special characters with the desired characters as follows,

import string
specialCharacterText = "H#y #@w @re &*)?"
inCharSet = "!@#$%^&*()[]{};:,./<>?\|`~-=_+\""
outCharSet = "                               " #corresponding characters in inCharSet to be replaced
splCharReplaceList = string.maketrans(inCharSet, outCharSet)
splCharFreeString = specialCharacterText.translate(splCharReplaceList)

This is for Visual Studio 2019, After trying a lot of suggestions that failed to work (including changing the port number etc) I solved my problem by deleting a file that was generated on my project's root folder called "debug". As soon as this file was deleted everything started working.

TLDR Summary

In modern MongoDB releases you can brute force this with $slice just off the basic aggregation result. For "large" results, run parallel queries instead for each grouping ( a demonstration listing is at the end of the answer ), or wait for SERVER-9377 to resolve, which would allow a "limit" to the number of items to $push to an array.

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 },
    { "$project": {
        "books": { "$slice": [ "$books", 2 ] },
        "count": 1
    }}
])

MongoDB 3.6 Preview

Still not resolving SERVER-9377, but in this release $lookup allows a new "non-correlated" option which takes an "pipeline" expression as an argument instead of the "localFields" and "foreignFields" options. This then allows a "self-join" with another pipeline expression, in which we can apply $limit in order to return the "top-n" results.

db.books.aggregate([
  { "$group": {
    "_id": "$addr",
    "count": { "$sum": 1 }
  }},
  { "$sort": { "count": -1 } },
  { "$limit": 2 },
  { "$lookup": {
    "from": "books",
    "let": {
      "addr": "$_id"
    },
    "pipeline": [
      { "$match": { 
        "$expr": { "$eq": [ "$addr", "$$addr"] }
      }},
      { "$group": {
        "_id": "$book",
        "count": { "$sum": 1 }
      }},
      { "$sort": { "count": -1  } },
      { "$limit": 2 }
    ],
    "as": "books"
  }}
])

The other addition here is of course the ability to interpolate the variable through $expr using $match to select the matching items in the "join", but the general premise is a "pipeline within a pipeline" where the inner content can be filtered by matches from the parent. Since they are both "pipelines" themselves we can $limit each result separately.

This would be the next best option to running parallel queries, and actually would be better if the $match were allowed and able to use an index in the "sub-pipeline" processing. So which is does not use the "limit to $push" as the referenced issue asks, it actually delivers something that should work better.

Original Content

You seem have stumbled upon the top "N" problem. In a way your problem is fairly easy to solve though not with the exact limiting that you ask for:

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 }
])

Now that will give you a result like this:

{
    "result" : [
            {
                    "_id" : "address1",
                    "books" : [
                            {
                                    "book" : "book4",
                                    "count" : 1
                            },
                            {
                                    "book" : "book5",
                                    "count" : 1
                            },
                            {
                                    "book" : "book1",
                                    "count" : 3
                            }
                    ],
                    "count" : 5
            },
            {
                    "_id" : "address2",
                    "books" : [
                            {
                                    "book" : "book5",
                                    "count" : 1
                            },
                            {
                                    "book" : "book1",
                                    "count" : 2
                            }
                    ],
                    "count" : 3
            }
    ],
    "ok" : 1
}

So this differs from what you are asking in that, while we do get the top results for the address values the underlying "books" selection is not limited to only a required amount of results.

This turns out to be very difficult to do, but it can be done though the complexity just increases with the number of items you need to match. To keep it simple we can keep this at 2 matches at most:

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 },
    { "$unwind": "$books" },
    { "$sort": { "count": 1, "books.count": -1 } },
    { "$group": {
        "_id": "$_id",
        "books": { "$push": "$books" },
        "count": { "$first": "$count" }
    }},
    { "$project": {
        "_id": {
            "_id": "$_id",
            "books": "$books",
            "count": "$count"
        },
        "newBooks": "$books"
    }},
    { "$unwind": "$newBooks" },
    { "$group": {
      "_id": "$_id",
      "num1": { "$first": "$newBooks" }
    }},
    { "$project": {
        "_id": "$_id",
        "newBooks": "$_id.books",
        "num1": 1
    }},
    { "$unwind": "$newBooks" },
    { "$project": {
        "_id": "$_id",
        "num1": 1,
        "newBooks": 1,
        "seen": { "$eq": [
            "$num1",
            "$newBooks"
        ]}
    }},
    { "$match": { "seen": false } },
    { "$group":{
        "_id": "$_id._id",
        "num1": { "$first": "$num1" },
        "num2": { "$first": "$newBooks" },
        "count": { "$first": "$_id.count" }
    }},
    { "$project": {
        "num1": 1,
        "num2": 1,
        "count": 1,
        "type": { "$cond": [ 1, [true,false],0 ] }
    }},
    { "$unwind": "$type" },
    { "$project": {
        "books": { "$cond": [
            "$type",
            "$num1",
            "$num2"
        ]},
        "count": 1
    }},
    { "$group": {
        "_id": "$_id",
        "count": { "$first": "$count" },
        "books": { "$push": "$books" }
    }},
    { "$sort": { "count": -1 } }
])

So that will actually give you the top 2 "books" from the top two "address" entries.

But for my money, stay with the first form and then simply "slice" the elements of the array that are returned to take the first "N" elements.

Demonstration Code

The demonstration code is appropriate for usage with current LTS versions of NodeJS from v8.x and v10.x releases. That's mostly for the async/await syntax, but there is nothing really within the general flow that has any such restriction, and adapts with little alteration to plain promises or even back to plain callback implementation.

index.js

const { MongoClient } = require('mongodb');
const fs = require('mz/fs');

const uri = 'mongodb://localhost:27017';

const log = data => console.log(JSON.stringify(data, undefined, 2));

(async function() {

  try {
    const client = await MongoClient.connect(uri);

    const db = client.db('bookDemo');
    const books = db.collection('books');

    let { version } = await db.command({ buildInfo: 1 });
    version = parseFloat(version.match(new RegExp(/(?:(?!-).)*/))[0]);

    // Clear and load books
    await books.deleteMany({});

    await books.insertMany(
      (await fs.readFile('books.json'))
        .toString()
        .replace(/\n$/,"")
        .split("\n")
        .map(JSON.parse)
    );

    if ( version >= 3.6 ) {

    // Non-correlated pipeline with limits
      let result = await books.aggregate([
        { "$group": {

        "count": { "$sum": 1 }
      }},
      { "$sort": { "count": -1 } },
      { "$limit": 2 }
    ]).toArray();

    // Run parallel top books for each addr
    let topbooks = await Promise.all(
      topaddr.map(({ _id: addr }) =>
        books.aggregate([
          { "$match": { addr } },

          { "$limit": 2 }
        ]).toArray()
      )
    );

    // Merge output
    topaddr = topaddr.map((d,i) => ({ ...d, books: topbooks[i] }));
    log({ topaddr });

    client.close();

  } catch(e) {
    console.error(e)
  } finally {
    process.exit()

There're two kind of Django "projects" that I have in my ~/projects/ directory, both have a bit different structure.:

• Stand-alone websites
• Pluggable applications

Stand-alone website

Mostly private projects, but doesn't have to be. It usually looks like this:

~/projects/project_name/

docs/               # documentation
scripts/
  manage.py         # installed to PATH via setup.py
project_name/       # project dir (the one which django-admin.py creates)
  apps/             # project-specific applications
    accounts/       # most frequent app, with custom user model
    __init__.py
    ...
  settings/         # settings for different environments, see below
    __init__.py
    production.py
    development.py
    ...
        
  __init__.py       # contains project version
  urls.py
  wsgi.py
static/             # site-specific static files
templates/          # site-specific templates
tests/              # site-specific tests (mostly in-browser ones)
tmp/                # excluded from git
setup.py
requirements.txt
requirements_dev.txt
pytest.ini
...

Settings

The main settings are production ones. Other files (eg. staging.py, development.py) simply import everything from production.py and override only necessary variables.

For each environment, there are separate settings files, eg. production, development. I some projects I have also testing (for test runner), staging (as a check before final deploy) and heroku (for deploying to heroku) settings.

Requirements

I rather specify requirements in setup.py directly. Only those required for development/test environment I have in requirements_dev.txt.

Some services (eg. heroku) requires to have requirements.txt in root directory.

setup.py

Useful when deploying project using setuptools. It adds manage.py to PATH, so I can run manage.py directly (anywhere).

Project-specific apps

I used to put these apps into project_name/apps/ directory and import them using relative imports.

Templates/static/locale/tests files

I put these templates and static files into global templates/static directory, not inside each app. These files are usually edited by people, who doesn't care about project code structure or python at all. If you are full-stack developer working alone or in a small team, you can create per-app templates/static directory. It's really just a matter of taste.

The same applies for locale, although sometimes it's convenient to create separate locale directory.

Tests are usually better to place inside each app, but usually there is many integration/functional tests which tests more apps working together, so global tests directory does make sense.

Tmp directory

There is temporary directory in project root, excluded from VCS. It's used to store media/static files and sqlite database during development. Everything in tmp could be deleted anytime without any problems.

Virtualenv

I prefer virtualenvwrapper and place all venvs into ~/.venvs directory, but you could place it inside tmp/ to keep it together.

Project template

I've created project template for this setup, django-start-template

Deployment

Deployment of this project is following:

source $VENV/bin/activate
export DJANGO_SETTINGS_MODULE=project_name.settings.production
git pull
pip install -r requirements.txt

# Update database, static files, locales
manage.py syncdb  --noinput
manage.py migrate
manage.py collectstatic --noinput
manage.py makemessages -a
manage.py compilemessages

# restart wsgi
touch project_name/wsgi.py

You can use rsync instead of git, but still you need to run batch of commands to update your environment.

Recently, I made django-deploy app, which allows me to run single management command to update environment, but I've used it for one project only and I'm still experimenting with it.

Sketches and drafts

Draft of templates I place inside global templates/ directory. I guess one can create folder sketches/ in project root, but haven't used it yet.

Pluggable application

These apps are usually prepared to publish as open-source. I've taken example below from django-forme

~/projects/django-app/

docs/
app/
tests/
example_project/
LICENCE
MANIFEST.in
README.md
setup.py
pytest.ini
tox.ini
.travis.yml
...

Name of directories is clear (I hope). I put test files outside app directory, but it really doesn't matter. It is important to provide README and setup.py, so package is easily installed through pip.

vagrant plugin install vagrant-vbguest
vagrant destroy #clean rhel/yum repos
vagrant up

And on the config file:

config.vbguest.auto_update = false #important so that any changes to the base image don't affect on reload

I got the same problem with dotnet core and managed to fix it by clearing the NuGet cache.

Open the powershell and enter the following command.

dotnet nuget locals all --clear

Then I closed Visual Studio, opened it again and entered the following command into the Package Manager Console:

Update-Package

NuGet should now restore all packages and popultes the nuget cache again.

After that I was able to build and start my dotnet core webapi in a Linux container.

I had to change the js file, so to include "function()" at the beginning of it, and also "()" at the end line. That solved the problem

You want to use URI templates. Look carefully at the README of this project: URLEncoder.encode() does NOT work for URIs.

Let us take your original URL:

http://site-test.test.com/Meetings/IC/DownloadDocument?meetingId=c21c905c-8359-4bd6-b864-844709e05754&itemId=a4b724d1-282e-4b36-9d16-d619a807ba67&file=\s604132shvw140\Test-Documents\c21c905c-8359-4bd6-b864-844709e05754_attachments\7e89c3cb-ce53-4a04-a9ee-1a584e157987\myDoc.pdf

and convert it to a URI template with two variables (on multiple lines for clarity):

http://site-test.test.com/Meetings/IC/DownloadDocument
    ?meetingId={meetingID}&itemId={itemID}&file={file}

Now let us build a variable map with these three variables using the library mentioned in the link:

final VariableMap = VariableMap.newBuilder()
    .addScalarValue("meetingID", "c21c905c-8359-4bd6-b864-844709e05754")
    .addScalarValue("itemID", "a4b724d1-282e-4b36-9d16-d619a807ba67e")
    .addScalarValue("file", "\\\\s604132shvw140\\Test-Documents"
        + "\\c21c905c-8359-4bd6-b864-844709e05754_attachments"
        + "\\7e89c3cb-ce53-4a04-a9ee-1a584e157987\\myDoc.pdf")
    .build();

final URITemplate template
    = new URITemplate("http://site-test.test.com/Meetings/IC/DownloadDocument"
        + "meetingId={meetingID}&itemId={itemID}&file={file}");

// Generate URL as a String
final String theURL = template.expand(vars);

This is GUARANTEED to return a fully functional URL!

Setting the HttpWebRequest.KeepAlive to false didn't work for me.

Since I was accessing a HTTPS page I had to set the Service Point Security Protocol to Tls12.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Notice that there are other SecurityProtocolTypes: SecurityProtocolType.Ssl3, SecurityProtocolType.Tls, SecurityProtocolType.Tls11

So if the Tls12 doesn't work for you, try the three remaining options.

Also notice that you can set multiple protocols. This is preferable on most cases.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;

Edit: Since this is a choice of security standards it's obviously best to go with the latest (TLS 1.2 as of writing this), and not just doing what works. In fact, SSL3 has been officially prohibited from use since 2015 and TLS 1.0 and TLS 1.1 will likely be prohibited soon as well. source: @aske-b

import json

list = [{'id': 123, 'data': 'qwerty', 'indices': [1,10]}, {'id': 345, 'data': 'mnbvc', 'indices': [2,11]}]

Write to json File:

with open('/home/ubuntu/test.json', 'w') as fout:
    json.dump(list , fout)

Read Json file:

with open(r"/home/ubuntu/test.json", "r") as read_file:

Let's say your script is called my_script.py and you have put it in your Downloads folder.

There are many ways of installing Python, but homebrew is the easiest.

0) Open Terminal.app

1) Install homebrew (by pasting the following text into Terminal.app and pressing the Enter key)

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2) Install Python using homebrew

brew install python

3) cd into the directory that contains your Python script (as an example I'm using the Downloads (Downloads) folder in your home (~) folder):

cd ~/Downloads

4) Run the script using the python3 executable

python3 my_script.py

You can also skip step 3 and give python3 an absolute path instead

python3 ~/Downloads/my_script.py

Instead of typing out that whole thing (~/Downloads/my_script.py), you can find the .py file in Finder.app and just drag it into the Terminal.app window which should type out the path for you.

If you have spaces or certain other symbols somewhere in your filename you need to enclose the file name in quotes:

python3 "~/Downloads/some directory with spaces/and a filename with a | character.py"

Note that you need to install it as brew install python but later use the command python3 (with a 3 at the end).

Do ctrl+F5 to compile and run your project without debugging. Look at the output pane (defaults to "Show output from Build"). If it compiled successfully, the path to the .exe file should be there after {projectname}.vcxproj ->

Ok, so very important to realize the implications here.

Docs say that SSL over 465 is NOT supported in SmtpClient.

Seems like you have no choice but to use STARTTLS which may not be supported by your mail host. You may have to use a different library if your host requires use of SSL over 465.

Quoted from http://msdn.microsoft.com/en-us/library/system.net.mail.smtpclient.enablessl(v=vs.110).aspx

The SmtpClient class only supports the SMTP Service Extension for Secure SMTP over Transport Layer Security as defined in RFC 3207. In this mode, the SMTP session begins on an unencrypted channel, then a STARTTLS command is issued by the client to the server to switch to secure communication using SSL. See RFC 3207 published by the Internet Engineering Task Force (IETF) for more information.

An alternate connection method is where an SSL session is established up front before any protocol commands are sent. This connection method is sometimes called SMTP/SSL, SMTP over SSL, or SMTPS and by default uses port 465. This alternate connection method using SSL is not currently supported.

If it is not your build tools, check your strings, styles, attrs, ... XML files and ensure they are correct. For example a string with an empty name-attribute

<string name="">Test"</string>

or a previously undefined attr without a format specified (attrs.xml):

<declare-styleable name="MediaGridView">
    <attr name="allowVideo"/>
</declare-styleable>

In your application.properties file -

/src/main/resources/application.properties

Change the port number to something like this -

server.port=8181

Or alternatively you can provide alternative port number while executing your jar file - java -jar resource-server/build/libs/resource-server.jar --server.port=8888

In your script, why are you using single quotes around the variables? These will not be expanded. Use double quotes for variable expansion or just the variable names themselves.

unzipRelease –Src '$ReleaseFile' -Dst '$Destination'

to

unzipRelease –Src "$ReleaseFile" -Dst "$Destination"

In our case we were getting UnmarshalException because a wrong Java package was specified in the following. The issue was resolved once the right package was in place:

@Bean
public Unmarshaller tmsUnmarshaller() {
    final Jaxb2Marshaller jaxb2Marshaller = new Jaxb2Marshaller();
    jaxb2Marshaller
            .setPackagesToScan("java.package.to.generated.java.classes.for.xsd");
    return jaxb2Marshaller;
}

In the case that

pip install -U numpy 

doesn't work (even with sudo), you may want to make sure you're using the right version of numpy. I had the same "numpy.core.multiarray failed to import" issue, but it was because I had 1.6 installed for the version of Python I was using, even though I kept installing 1.8 and assumed it was installing in the right directory.

I found the bad numpy version by using the following command in my Mac terminal:

python -c "import numpy;print(numpy.__version__);print(numpy.__file__)";

This command gave me the version and location of numpy that I was using (turned out it was 1.6.2). I went to this location and manually replaced it with the numpy folder for 1.8, which resolved my "numpy.core.multiarray failed to import" issue. Hopefully someone finds this useful!

Note: For the command, use double underscore before and after 'version' and 'file'

For someone not using the signing configs and trying to test out the Cordova Release command by typing all the parameters at command line, you may need to enclose your passwords with single quotes if you have special characters in your password

cordova run android --release -- --keystore=../my-release-key.keystore --storePassword='password' --alias=alias_name --password='password'

One way to do this if dealing with sorted range index is:

data = data.sort_index(ascending=False)

This approach has the benefits of (1) being a single line, (2) not requiring a utility function, and most importantly (3) not actually changing any of the data in the dataframe.

Caveat: this works by sorting the index in descending order and so may not always be appropriate or generalize for any given Dataframe.

I think df['word'].value_counts() should serve. By skipping the groupby machinery, you'll save some time. I'm not sure why count should be much slower than max. Both take some time to avoid missing values. (Compare with size.)

In any case, value_counts has been specifically optimized to handle object type, like your words, so I doubt you'll do much better than that.

We need to do the following changes/fixes in our earlier onActivityResult()'s gallery picker code to run seamlessly on Android 4.4 (KitKat) and on all other earlier versions as well.

Uri selectedImgFileUri = data.getData();

if (selectedImgFileUri == null ) {

    // The user has not selected any photo
}

try {

   InputStream input = mActivity.getContentResolver().openInputStream(selectedImgFileUri);
   mSelectedPhotoBmp = BitmapFactory.decodeStream(input);
}
catch (Throwable tr) {

    // Show message to try again
}

I did not want to install visual studio and development environment, so I have installed AspNetMVC4Setup.exe in Windows server 2016 machine and it solved the problem. The installer was downloaded from Microsoft website.

The better use you can specify the limit of your file size as it is shown in the given lines:

app.use(bodyParser.json({limit: '10mb', extended: true}))
app.use(bodyParser.urlencoded({limit: '10mb', extended: true}))

You can also change the default setting in node-modules body-parser then in the lib folder, there are JSON and text file. Then change limit here. Actually, this condition pass if you don't pass the limit parameter in the given line app.use(bodyParser.json({limit: '10mb', extended: true})).

About the version of Android SDK Build-tools, the answer is

By default, the Android SDK uses the most recent downloaded version of the Build Tools.

Source

In Eclipse, you can choose a specific version by using the sdk.buildtools property in the project.properties file.

There seems to be no official page explaining all the build tools. Here is what the Android team says about this.

The [build] tools, such as aidl, aapt, dexdump, and dx, are typically called by the Android build tools or Android Development Tools (ADT), so you rarely need to invoke these tools directly. As a general rule, you should rely on the build tools or the ADT plugin to call them as needed.

Source

Anyway, here is a synthesis of the differences between tools, platform-tools and build-tools:

• Android SDK Tools
  • Location: $ANDROID_HOME/tools
  • Main tools: ant scripts (to build your APKs) and ddms (for debugging)
• Android SDK Platform-tools
  • Location: $ANDROID_HOME/platform-tools
  • Main tool: adb (to manage the state of an emulator or an Android device)
• Android SDK Build-tools
  • Location: $ANDROID_HOME/build-tools/$VERSION/
  • Documentation
  • Main tools: aapt (to generate R.java and unaligned, unsigned APKs), dx (to convert Java bytecode to Dalvik bytecode), and zipalign (to optimize your APKs)

Use $ne (for "not equal")

db.collection.find({ "fieldToCheck": { $exists: true, $ne: null } })

If you are using Oracle 10g, you can use the DECODE function to pivot the rows into columns:

CREATE TABLE doc_tab (
  loan_number VARCHAR2(20),
  document_type VARCHAR2(20),
  document_id VARCHAR2(20)
);

INSERT INTO doc_tab VALUES('992452533663', 'Voters ID', 'XPD0355636');
INSERT INTO doc_tab VALUES('992452533663', 'Pan card', 'CHXPS5522D');
INSERT INTO doc_tab VALUES('992452533663', 'Drivers licence', 'DL-0420110141769');

COMMIT;

SELECT
    loan_number,
    MAX(DECODE(document_type, 'Voters ID', document_id)) AS voters_id,
    MAX(DECODE(document_type, 'Pan card', document_id)) AS pan_card,
    MAX(DECODE(document_type, 'Drivers licence', document_id)) AS drivers_licence
  FROM
    doc_tab
GROUP BY loan_number
ORDER BY loan_number;

Output:

LOAN_NUMBER   VOTERS_ID            PAN_CARD             DRIVERS_LICENCE    
------------- -------------------- -------------------- --------------------
992452533663  XPD0355636           CHXPS5522D           DL-0420110141769     

You can achieve the same using Oracle PIVOT clause, introduced in 11g:

SELECT *
  FROM doc_tab
PIVOT (
  MAX(document_id) FOR document_type IN ('Voters ID','Pan card','Drivers licence')
);

For those who is still using @Paul Burke's code with Android SDK version 23 and above, if your project met the error saying that you are missing EXTERNAL_PERMISSION, and you are very sure you have already added user-permission in your AndroidManifest.xml file. That's because you may in Android API 23 or above and Google make it necessary to guarantee permission again while you make the action to access the file in runtime.

That means: If your SDK version is 23 or above, you are asked for READ & WRITE permission while you are selecting the picture file and want to know the URI of it.

And following is my code, in addition to Paul Burke's solution. I add these code and my project start to work fine.

private static final int REQUEST_EXTERNAL_STORAGE = 1;
private static final String[] PERMISSINOS_STORAGE = {
    Manifest.permission.READ_EXTERNAL_STORAGE,
    Manifest.permission.WRITE_EXTERNAL_STORAGE
};

public static void verifyStoragePermissions(Activity activity) {
    int permission = ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);

    if (permission != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(
                activity,
                PERMISSINOS_STORAGE,
                REQUEST_EXTERNAL_STORAGE
        );
    }
}

And in your activity&fragment where you are asking for the URI:

private void pickPhotoFromGallery() {

    CompatUtils.verifyStoragePermissions(this);
    Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
    intent.setType("image/*");
    // startActivityForResult(intent, REQUEST_PHOTO_LIBRARY);
    startActivityForResult(Intent.createChooser(intent, "????"),
            REQUEST_PHOTO_LIBRARY);
}

In my case, CompatUtils.java is where I define the verifyStoragePermissions method (as static type so I can call it within other activity).

Also it should make more sense if you make an if state first to see whether the current SDK version is above 23 or not before you call the verifyStoragePermissions method.

Follow bellow steps:

shell> mysqldump -hlocalhost -uroot -p  database1  > dump.sql

mysql> CREATE DATABASE database2;

shell> mysql -hlocalhost -uroot -p database2 < dump.sql

If you want to drop database1 otherwise leave it.

mysql> DROP DATABASE database1;

Note : shell> denote command prompt and mysql> denote mysql prompt.

You can use XMLHttpRequest() method:

    var xmlhttp = new XMLHttpRequest();
    xmlhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
        var myObj = JSON.parse(this.responseText);
        //console.log("Json parsed data is: " + JSON.stringify(myObj));
       }
    };
xmlhttp.open("GET", "your_file_name.json", true);
xmlhttp.send();

You can see the response of myObj using console.log statement(commented out).

If you know AngularJS, you can use $http:

MyController.$inject = ['myService'];
function MyController(myService){

var promise = myService.getJsonFileContents();

  promise.then(function (response) {
    var results = response.data;
    console.log("The JSON response is: " + JSON.stringify(results));
})
  .catch(function (error) {
    console.log("Something went wrong.");
  });
}

myService.$inject = ['$http'];
function myService($http){

var service = this;

  service.getJsonFileContents = function () {
    var response = $http({
      method: "GET",
      url: ("your_file_name.json")
    });

    return response;
  };
}

If you have the file in a different folder, mention the complete path instead of filename.

The gcf method is depricated in V 0.14, The below code works for me:

plot = dtf.plot()
fig = plot.get_figure()
fig.savefig("output.png")

xcopy "%userprofile%\Desktop\?????????" "D:\Backup\" /s/h/e/k/f/c

should work, assuming that your language setting allows Cyrillic (or you use Unicode fonts in the console).

For reference about the arguments: http://ss64.com/nt/xcopy.html

Just an obvious but possible helpful hint....remember to check that the new version you specify in your webconfig assembly binding is the same version that you reference in your project references. (ie as I write this...this would be 5.1.0.0 if you have recently done a NUGet on System.Web.Http

So the package will be downloaded in a temp folder C:\Users\U122337.BOSTONADVISORS\AppData\Local\Temp\Rtmp404t8Y\downloaded_packages from where it will be installed into your library folder, e.g. C:\R\library\zoo

What you have to do once install command is done: Open Packages menu -> Load package...

You will see your package on the list. You can automate this: How to load packages in R automatically?

I recommend using .htaccess. You only need to add:

DirectoryIndex home.php

or whatever page name you want to have for it.

EDIT: basic htaccess tutorial.

1) Create .htaccess file in the directory where you want to change the index file.

• no extension
• . in front, to ensure it is a "hidden" file

Enter the line above in there. There will likely be many, many other things you will add to this (AddTypes for webfonts / media files, caching for headers, gzip declaration for compression, etc.), but that one line declares your new "home" page.

2) Set server to allow reading of .htaccess files (may only be needed on your localhost, if your hosting servce defaults to allow it as most do)

Assuming you have access, go to your server's enabled site location. I run a Debian server for development, and the default site setup is at /etc/apache2/sites-available/default for Debian / Ubuntu. Not sure what server you run, but just search for "sites-available" and go into the "default" document. In there you will see an entry for Directory. Modify it to look like this:

<Directory /var/www/>
    Options Indexes FollowSymLinks MultiViews
    AllowOverride None
    Order allow,deny
    allow from all
</Directory>

Then restart your apache server. Again, not sure about your server, but the command on Debian / Ubuntu is:

sudo service apache2 restart

Technically you only need to reload, but I restart just because I feel safer with a full refresh like that.

Once that is done, your site should be reading from your .htaccess file, and you should have a new default home page! A side note, if you have a sub-directory that runs a site (like an admin section or something) and you want to have a different "home page" for that directory, you can just plop another .htaccess file in that sub-site's root and it will overwrite the declaration in the parent.

My Code to insert data is not working. It showing no error but data is not showing in my database.

public partial class Form1 : Form { OleDbConnection connection = new OleDbConnection(check.Properties.Settings.Default.KitchenConnectionString); public Form1() { InitializeComponent(); }

    private void Form1_Load(object sender, EventArgs e)
    {
        
    }

    private void btn_add_Click(object sender, EventArgs e)
    {
        OleDbDataAdapter items = new OleDbDataAdapter();
        connection.Open();
        OleDbCommand command = new OleDbCommand("insert into Sets(SetId, SetName,  SetPassword) values('"+txt_id.Text+ "','" + txt_setname.Text + "','" + txt_password.Text + "');", connection);
        command.CommandType = CommandType.Text;
        command.ExecuteReader();
        connection.Close();
        MessageBox.Show("Insertd!");
    }
}

For your case Elasticdump is the perfect answer.
First, you need to download the mapping and then the index

# Install the elasticdump 
npm install elasticdump -g

# Dump the mapping 
elasticdump --input=http://<your_es_server_ip>:9200/index --output=es_mapping.json --type=mapping

# Dump the data
elasticdump --input=http://<your_es_server_ip>:9200/index --output=es_index.json --type=data    

If you want to dump the data on any server I advise you to install esdump through docker. You can get more info from this website Blog Link

Exit code 137 (128+9) indicates that your program exited due to receiving signal 9, which is SIGKILL. This also explains the killed message. The question is, why did you receive that signal?

The most likely reason is probably that your process crossed some limit in the amount of system resources that you are allowed to use. Depending on your OS and configuration, this could mean you had too many open files, used too much filesytem space or something else. The most likely is that your program was using too much memory. Rather than risking things breaking when memory allocations started failing, the system sent a kill signal to the process that was using too much memory.

As I commented earlier, one reason you might hit a memory limit after printing finished counting is that your call to counter.items() in your final loop allocates a list that contains all the keys and values from your dictionary. If your dictionary had a lot of data, this might be a very big list. A possible solution would be to use counter.iteritems() which is a generator. Rather than returning all the items in a list, it lets you iterate over them with much less memory usage.

So, I'd suggest trying this, as your final loop:

for key, value in counter.iteritems():
    writer.writerow([key, value])

Note that in Python 3, items returns a "dictionary view" object which does not have the same overhead as Python 2's version. It replaces iteritems, so if you later upgrade Python versions, you'll end up changing the loop back to the way it was.

Even better use implicit remoting to use a module from another Machine!

$s = New-PSSession Server-Name
Invoke-Command -Session $s -ScriptBlock {Import-Module ActiveDirectory}
Import-PSSession -Session $s -Module ActiveDirectory -Prefix REM

This will allow you to use the module off a remote PC for as long as the PSSession is connected.

You need to detect the click from js side, your HTML remaining same. Note: this method is deprecated since v3.5.5 and removed in v4.

$("button").click(function() {
    var $btn = $(this);
    $btn.button('loading');
    // simulating a timeout
    setTimeout(function () {
        $btn.button('reset');
    }, 1000);
});

Official Documentation

If you need to loop inside a directory recursively for a particular kind of file, use the below command, which filters all the files of doc file type

$fileNames = Get-ChildItem -Path $scriptPath -Recurse -Include *.doc

If you need to do the filteration on multiple types, use the below command.

$fileNames = Get-ChildItem -Path $scriptPath -Recurse -Include *.doc,*.pdf

Now $fileNames variable act as an array from which you can loop and apply your business logic.

There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.

Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly,

void Similarity::readData(Scanner& inStream){
}

not

void readData(Scanner& inStream){
}

etc. etc.

The second one is a function called readData, only the first is the readData method of the Similarity class.

To be clear about this, in Similarity.h

void readData(Scanner& inStream);

but in Similarity.cpp

void Similarity::readData(Scanner& inStream){
}

My code was out of void setup() or void loop() in Arduino.

To escape the backslash, simply use 2 of them, like this: \\

If you need to escape other things, this may be helpful..

Use the Out-File cmdlet

 Compare-Object ... | Out-File C:\filename.txt

Optionally, add -Encoding utf8 to Out-File as the default encoding is not really ideal for many uses.

In VS 2013 I saw this error after setting up Google Docs synchronization on My Documents. Updated permissions to not be read-only and problem solved.

$ cd "$DOCS"

You need to quote "$DOCS" to prevent spaces from being parsed as word separators. More often than not, variable references should be quoted.

Note that $HOME would have the same problem. The issue is coming from when the shell evaluates variable references; it's nothing to do with what variables you use or how you assign to them. It's the expansion that needs to be quoted.

$ echo $HOME
/home/my dir

This is deceptive. echo is actually echoing the two strings /home/my and dir. If you use cd or ls you'll see how it's actually working.

$ ls $HOME
ls: cannot access /home/my: No such file or directory
ls: cannot access dir: No such file or directory
$ cd $HOME
bash: cd: /home/my: No such file or directory
$ cd "$HOME"
<success!>

Can I ask why it works when I manually type it in but not in a variable?

Great question! Let's examine the commands you typed:

$ DOCS="\"/cygdrive/c/Users/my dir/Documents\""
$ echo $DOCS
"/cygdrive/c/Users/my dir/Documents"
$ cd $DOCS
-bash: cd: "/cygdrive/c/Users/my: No such file or directory

The reason this doesn't work is because Bash doesn't parse quotes inside variable expansions. It does perform word splitting, so whitespace in unquoted variable expansions is taken as word separators. It doesn't parse quotes in any way, meaning you can't put double quotes inside a variable to override word splitting.

$ cd $DOCS

Because of this, cd is passed two parameters. As far as cd knows it looks like you wrote:

$ cd '"/cygdrive/c/Users/my' 'dir/Documents"'

Two parameters, with double quotes intact.

This could be done in newer versions of selenium in JS( but all supporting stalenessOf will work):

 const { until } = require('selenium-webdriver');
 driver.wait(
        until.stalenessOf(
          driver.findElement(
            By.css(SQLQueriesByPhpMyAdminSelectors.sqlQueryArea)
          )
        ),
        5 * 1000
      )
      .then( driver.findElement(By.css(SQLQueriesByPhpMyAdminSelectors.sqlQueryArea))
      .sendKeys(sqlString)
  );

In the code of the button that saves the changes to the database eg the update button, add the following lines of code:

MyDataGridView.DataSource = MyTableBindingSource

MyDataGridView.Update()

MyDataGridView.RefreshEdit()

For anyone looking to do this on Centos 7 or with another system running SystemD, you change it in

/etc/sysconfig/elasticsearch 

Uncomment the ES_HEAP_SIZE line, and set a value, eg:

# Heap Size (defaults to 256m min, 1g max)
ES_HEAP_SIZE=16g

(Ignore the comment about 1g max - that's the default)

Sometimes spacing and Order of parameters in connection string matters (based on personal experience and a long night :S)

So stick to the standard format here

Server=myServerAddress; Port=1234; Database=myDataBase; Uid=myUsername; Pwd=myPassword;

See the github help on cloning URL. With HTTPS, if you are not authorized to push, you would basically have a read-only access. So yes, you need to ask the author to give you permission.

If the author doesn't give you permission, you can always fork (clone) his repository and work on your own. Once you made a nice and tested feature, you can then send a pull request to the original author.

Difficult to give code examples in the comments.

To read the words in the file, you can read the contents of the file, which gets you a string - this is what you were doing before, with the read() method - and then use split() to get the individual words. Split breaks up a String on the delimiter provided, or on whitespace by default. For example,

"the quick brown fox".split()

produces

['the', 'quick', 'brown', 'fox']

Similarly,

fileScan.read().split()

will give you an array of Strings. Hope that helps!

Add this to the beginning of your file:

Set WshShell = WScript.CreateObject("WScript.Shell")
If WScript.Arguments.Length = 0 Then
  Set ObjShell = CreateObject("Shell.Application")
  ObjShell.ShellExecute "wscript.exe" _
    , """" & WScript.ScriptFullName & """ RunAsAdministrator", , "runas", 1
  WScript.Quit
End if

There are many ways to get a path. See CurrentDirrectory mentioned. Also, you can get the full file name of your application by using Assembly.GetExecutingAssembly().Location and then use Path class to get a directory name.

When you have everything #included, an unresolved external symbol is often a missing * or & in the declaration or definition of a function.

The short answer is adb is used via command line. find adb.exe on your machine, add it to the path and use it from cmd on windows.

"adb devices" will give you a list of devices adb can talk to. your emulation platform should be on the list. just type adb to get a list of commands and what they do.

Alternative syntax using the -Not operator and depending on your preference for readability:

if( -Not (Test-Path -Path $TARGETDIR ) )
{
    New-Item -ItemType directory -Path $TARGETDIR
}

If you only need to modify the page num you can replace it:

var newUrl = location.href.replace("page="+currentPageNum, "page="+newPageNum);

I had this issue when i refereed a library project from a console application, and the library project was using a nuget package which is not refereed in the console application. Referring the same package in the console application helped to resolve this issue.

Seeing the Inner exception can help.

For what it's worth, the problem in my case was caused by using '/' as the directory separator in a copy command. Must use backslashes.

$ whereis java

java: /usr/bin/java /usr/lib/java /usr/bin/X11/java /usr/share/java /usr/share/man/man1/java.1.gz

Try using the success() call back

$http.get('/Documents/DocumentsList/' + caseId).success(function (result) {
    $scope.Documents = result;
});

But now since Documents is an array and not a promise, remove the ()

<li ng-repeat="document in Documents" ng-class="IsFiltered(document.Filtered)"> <span>
           <input type="checkbox" name="docChecked" id="doc_{{document.Id}}" ng-model="document.Filtered" />
        </span>
 <span>{{document.Name}}</span>

</li>

Before data bind change gridview databinding method, assign GridView.EditIndex to -1. It solved the same issue for me :

 gvTypes.EditIndex = -1;
 gvTypes.DataBind();

gvTypes is my GridView ID.

Here are both way of saving data with insertMany and save

1) Mongoose save array of documents with insertMany in bulk

/* write mongoose schema model and export this */
var Potato = mongoose.model('Potato', PotatoSchema);

/* write this api in routes directory  */
router.post('/addDocuments', function (req, res) {
    const data = [/* array of object which data need to save in db */];

    Potato.insertMany(data)  
    .then((result) => {
            console.log("result ", result);
            res.status(200).json({'success': 'new documents added!', 'data': result});
    })
    .catch(err => {
            console.error("error ", err);
            res.status(400).json({err});
    });
})

2) Mongoose save array of documents with .save()

These documents will save parallel.

/* write mongoose schema model and export this */
var Potato = mongoose.model('Potato', PotatoSchema);

/* write this api in routes directory  */
router.post('/addDocuments', function (req, res) {
    const saveData = []
    const data = [/* array of object which data need to save in db */];
    data.map((i) => {
        console.log(i)
        var potato = new Potato(data[i])
        potato.save()
        .then((result) => {
            console.log(result)
            saveData.push(result)
            if (saveData.length === data.length) {
                res.status(200).json({'success': 'new documents added!', 'data': saveData});
            }
        })
        .catch((err) => {
            console.error(err)
            res.status(500).json({err});
        })
    })
})

total count the documents where the value of the field is not equal to the specified value.

async function getRegisterUser() {
    return Login.count({"role": { $ne: 'Super Admin' }}, (err, totResUser) => {
        if (err) {
            return err;
        }
        return totResUser;
    })
}

Declare them outside the subroutines, like this:

Public wbA as Workbook
Public wbB as Workbook
Sub MySubRoutine()
    Set wbA = Workbooks.Open("C:\file.xlsx")
    Set wbB = Workbooks.Open("C:\file2.xlsx")
    OtherSubRoutine
End Sub
Sub OtherSubRoutine()
    MsgBox wbA.Name, vbInformation
End Sub

Alternately, you can pass variables between subroutines:

Sub MySubRoutine()
Dim wbA as Workbook
Dim wbB as Workbook
    Set wbA = Workbooks.Open("C:\file.xlsx")
    Set wbB = Workbooks.Open("C:\file2.xlsx")
    OtherSubRoutine wbA, wbB
End Sub
Sub OtherSubRoutine(wb1 as Workbook, wb2 as Workbook)
    MsgBox wb1.Name, vbInformation
    MsgBox wb2.Name, vbInformation
End Sub

Or use Functions to return values:

Sub MySubroutine()
    Dim i as Long
    i = MyFunction()
    MsgBox i
End Sub
Function MyFunction()
    'Lots of code that does something
    Dim x As Integer, y as Double
    For x = 1 to 1000
        'Lots of code that does something
    Next
    MyFunction = y
End Function

In the second method, within the scope of OtherSubRoutine you refer to them by their parameter names wb1 and wb2. Passed variables do not need to use the same names, just the same variable types. This allows you some freedom, for example you have a loop over several workbooks, and you can send each workbook to a subroutine to perform some action on that Workbook, without making all (or any) of the variables public in scope.

A Note About User Forms

Personally I would recommend keeping Option Explicit in all of your modules and forms (this prevents you from instantiating variables with typos in their names, like lCoutn when you meant lCount etc., among other reasons).

If you're using Option Explicit (which you should), then you should qualify module-scoped variables for style and to avoid ambiguity, and you must qualify user-form Public scoped variables, as these are not "public" in the same sense. For instance, i is undefined, though it's Public in the scope of UserForm1:

You can refer to it as UserForm1.i to avoid the compile error, or since forms are New-able, you can create a variable object to contain reference to your form, and refer to it that way:

NB: In the above screenshots x is declared Public x as Long in another standard code module, and will not raise the compilation error. It may be preferable to refer to this as Module2.x to avoid ambiguity and possible shadowing in case you re-use variable names...

If you're using Entity Framework, you can extend the default timeout (to give a long-running query more time to complete) by doing:

myDbContext.Database.CommandTimeout = 300;

Where myDbContext is your DbContext instance, and 300 is the timeout value in seconds.

(Syntax current as of Entity Framework 6.)

Here is my updated code. Checks to see if version exists before saving and saves as the next available version number.

Sub SaveNewVersion()
    Dim fileName As String, index As Long, ext As String
    arr = Split(ActiveWorkbook.Name, ".")
    ext = arr(UBound(arr))

    fileName = ActiveWorkbook.FullName

    If InStr(ActiveWorkbook.Name, "_v") = 0 Then
        fileName = ActiveWorkbook.Path & "\" & Left(ActiveWorkbook.Name, InStr(ActiveWorkbook.Name, ".") - 1) & "_v1." & ext
    End If

   Do Until Len(Dir(fileName)) = 0

        index = CInt(Split(Right(fileName, Len(fileName) - InStr(fileName, "_v") - 1), ".")(0))
        index = index + 1
        fileName = Left(fileName, InStr(fileName, "_v") - 1) & "_v" & index & "." & ext

    'Debug.Print fileName
   Loop

    ActiveWorkbook.SaveAs (fileName)
End Sub

Sql Server fire this error when your application don't have enough rights to access the database. there are several reason about this error . To fix this error you should follow the following instruction.

1. Try to connect sql server from your server using management studio . if you use windows authentication to connect sql server then set your application pool identity to server administrator .

2. if you use sql server authentication then check you connection string in web.config of your web application and set user id and password of sql server which allows you to log in .

3. if your database in other server(access remote database) then first of enable remote access of sql server form sql server property from sql server management studio and enable TCP/IP form sql server configuration manager .

4. after doing all these stuff and you still can't access the database then check firewall of server form where you are trying to access the database and add one rule in firewall to enable port of sql server(by default sql server use 1433 , to check port of sql server you need to check sql server configuration manager network protocol TCP/IP port).

5. if your sql server is running on named instance then you need to write port number with sql serer name for example 117.312.21.21/nameofsqlserver,1433.

6. If you are using cloud hosting like amazon aws or microsoft azure then server or instance will running behind cloud firewall so you need to enable 1433 port in cloud firewall if you have default instance or specific port for sql server for named instance.

7. If you are using amazon RDS or SQL azure then you need to enable port from security group of that instance.

8. If you are accessing sql server through sql server authentication mode them make sure you enabled "SQL Server and Windows Authentication Mode" sql server instance property.

   9. Restart your sql server instance after making any changes in property as some changes will require restart.

if you further face any difficulty then you need to provide more information about your web site and sql server .

ElektroStudios answer is a bit misleading.

"when you launch a bat file the working dir is the dir where it was launched" This is true if the user clicks on the batch file in the explorer.

However, if the script is called from another script using the CALL command, the current working directory does not change.

Thus, inside your script, it is better to use %~dp0subfolder\file1.txt

Please also note that %~dp0 will end with a backslash when the current script is not in the current working directory. Thus, if you need the directory name without a trailing backslash, you could use something like

call :GET_THIS_DIR
echo I am here: %THIS_DIR%
goto :EOF

:GET_THIS_DIR
pushd %~dp0
set THIS_DIR=%CD%
popd
goto :EOF

It seems like the $in operator would serve your purposes just fine.

You could do something like this (pseudo-query):

if (db.courses.find({"students" : {"$in" : [studentId]}, "course" : courseId }).count() > 0) {
  // student is enrolled in class
}

Alternatively, you could remove the "course" : courseId clause and get back a set of all classes the student is enrolled in.

Add your style here:

For some - possibly valid - reason the url was encoded twice. %25 is the urlencoded % sign. So the original url looked like:

http://server.com/my path/

Then it got urlencoded once:

http://server.com/my%20path/

and twice:

http://server.com/my%2520path/

So you should do no urlencoding - in your case - as other components seems to to that already for you. Use simply a space

Properly installing natecarlson's repository

If you really want to use natecarlson's repository, the instructions just below can do any of the following:

1. set it up from scratch
2. repair it if apt-get update gives a 404 error after add-apt-repository
3. repair it if apt-get update gives a NO_PUBKEY error after manually adding it to /etc/apt/sources.list

Open a terminal and run the following:

sudo -i

Enter your password if necessary, then paste the following into the terminal:

export GOOD_RELEASE='precise'
export BAD_RELEASE="`lsb_release -cs`"
cd /etc/apt
sed -i '/natecarlson\/maven3/d' sources.list
cd sources.list.d
rm -f natecarlson-maven3-*.list*
apt-add-repository -y ppa:natecarlson/maven3
mv natecarlson-maven3-${BAD_RELEASE}.list natecarlson-maven3-${GOOD_RELEASE}.list
sed -i "s/${BAD_RELEASE}/${GOOD_RELEASE}/" natecarlson-maven3-${GOOD_RELEASE}.list
apt-get update
exit
echo Done!

Removing natecarlson's repository

If you installed natecarlson's repository (either using add-apt-repository or manually added to /etc/apt/sources.list) and you don't want it anymore, open a terminal and run the following:

sudo -i

Enter your password if necessary, then paste the following into the terminal:

cd /etc/apt
sed -i '/natecarlson\/maven3/d' sources.list
cd sources.list.d
rm -f natecarlson-maven3-*.list*
apt-get update
exit
echo Done!

When in doubt, read the documentation:

filename = "C:\Temp\vblist.txt"

Set f = fso.OpenTextFile(filename)

Do Until f.AtEndOfStream
  WScript.Echo f.ReadLine
Loop

f.Close

The two int variables are defined in the header file. This means that every source file which includes the header will contain their definition (header inclusion is purely textual). The of course leads to multiple definition errors.

You have several options to fix this.

1. Make the variables static (static int WIDTH = 1024;). They will still exist in each source file, but their definitions will not be visible outside of the source file.

2. Turn their definitions into declarations by using extern (extern int WIDTH;) and put the definition into one source file: int WIDTH = 1024;.

3. Probably the best option: make the variables const (const int WIDTH = 1024;). This makes them static implicitly, and also allows them to be used as compile-time constants, allowing the compiler to use their value directly instead of issuing code to read it from the variable etc.

Assuming that you have your proxy settings correct, you may have missed out pointing Eclipse to the intended settings.xml file. This happens often when you have both Maven installed as a snap in, and an external installation outside Eclipse. You need to tell Eclipse which Maven installation it should use, and which settings.xml file it should be looking for.

First check that the settings.xml file contains your proxy settings.

Next, check that the user settings.xml file here contains your proxy settings.

If you have made any changes, restart Eclipse.

This could be an error in the web.config file.

Open up your URL in your browser, example:

I have observed that -

1. FtpwebRequest is missing.
2. As the target is FTP, so the NetworkCredential required.

I have prepared a method that works like this, you can replace the value of the variable ftpurl with the parameter TargetDestinationPath. I had tested this method on winforms application :

private void UploadProfileImage(string TargetFileName, string TargetDestinationPath, string FiletoUpload)
        {
            //Get the Image Destination path
            string imageName = TargetFileName; //you can comment this
            string imgPath = TargetDestinationPath; 

            string ftpurl = "ftp://downloads.abc.com/downloads.abc.com/MobileApps/SystemImages/ProfileImages/" + imgPath;
            string ftpusername = krayknot_DAL.clsGlobal.FTPUsername;
            string ftppassword = krayknot_DAL.clsGlobal.FTPPassword;
            string fileurl = FiletoUpload;

            FtpWebRequest ftpClient = (FtpWebRequest)FtpWebRequest.Create(ftpurl);
            ftpClient.Credentials = new System.Net.NetworkCredential(ftpusername, ftppassword);
            ftpClient.Method = System.Net.WebRequestMethods.Ftp.UploadFile;
            ftpClient.UseBinary = true;
            ftpClient.KeepAlive = true;
            System.IO.FileInfo fi = new System.IO.FileInfo(fileurl);
            ftpClient.ContentLength = fi.Length;
            byte[] buffer = new byte[4097];
            int bytes = 0;
            int total_bytes = (int)fi.Length;
            System.IO.FileStream fs = fi.OpenRead();
            System.IO.Stream rs = ftpClient.GetRequestStream();
            while (total_bytes > 0)
            {
                bytes = fs.Read(buffer, 0, buffer.Length);
                rs.Write(buffer, 0, bytes);
                total_bytes = total_bytes - bytes;
            }
            //fs.Flush();
            fs.Close();
            rs.Close();
            FtpWebResponse uploadResponse = (FtpWebResponse)ftpClient.GetResponse();
            string value = uploadResponse.StatusDescription;
            uploadResponse.Close();
        }

You put your template in the wrong place. From the Flask docs:

IUSR is part of IIS_IUSER group.so i guess you can remove the permissions for IUSR without worrying. Further Reading

However, a problem arose over time as more and more Windows system services started to run as NETWORKSERVICE. This is because services running as NETWORKSERVICE can tamper with other services that run under the same identity. Because IIS worker processes run third-party code by default (Classic ASP, ASP.NET, PHP code), it was time to isolate IIS worker processes from other Windows system services and run IIS worker processes under unique identities. The Windows operating system provides a feature called "Virtual Accounts" that allows IIS to create unique identities for each of its Application Pools. DefaultAppPool is the by default pool that is assigned to all Application Pool you create.

To make it more secure you can change the IIS DefaultAppPool Identity to ApplicationPoolIdentity.

Regarding permission, Create and Delete summarizes all the rights that can be given. So whatever you have assigned to the IIS_USERS group is that they will require. Nothing more, nothing less.

hope this helps.

With MongoDb 3.4.4 and newer, you can leverage the use of $arrayToObject operator and a $replaceRoot pipeline to get the counts.

For example, suppose you have a collection of users with different roles and you would like to calculate the distinct counts of the roles. You would need to run the following aggregate pipeline:

db.users.aggregate([
    { "$group": {
        "_id": { "$toLower": "$role" },
        "count": { "$sum": 1 }
    } },
    { "$group": {
        "_id": null,
        "counts": {
            "$push": { "k": "$_id", "v": "$count" }
        }
    } },
    { "$replaceRoot": {
        "newRoot": { "$arrayToObject": "$counts" }
    } }    
])

Example Output

{
    "user" : 67,
    "superuser" : 5,
    "admin" : 4,
    "moderator" : 12
}

The issue here is that input() returns a string in Python 3.x, so when you do your comparison, you are comparing a string and an integer, which isn't well defined (what if the string is a word, how does one compare a string and a number?) - in this case Python doesn't guess, it throws an error.

To fix this, simply call int() to convert your string to an integer:

int(input(...))

As a note, if you want to deal with decimal numbers, you will want to use one of float() or decimal.Decimal() (depending on your accuracy and speed needs).

Note that the more pythonic way of looping over a series of numbers (as opposed to a while loop and counting) is to use range(). For example:

def main():
    print("Let me Retire Financial Calculator")
    deposit = float(input("Please input annual deposit in dollars: $"))
    rate = int(input ("Please input annual rate in percentage: %")) / 100
    time = int(input("How many years until retirement?"))
    value = 0
    for x in range(1, time+1):
        value = (value * rate) + deposit
        print("The value of your account after" + str(x) + "years will be $" + str(value))

You need to include the reference to the assembly System.Web.Mvc in you project.

you may not have the System.Web.Mvc in your C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0

So you need to add it and then to include it as reference to your projrect

Since chrome has come up with the multiple profiles you will not get it directly in C:\Users\<Your_User_Name>\AppData\Local\Google\Chrome\User Data\Default\Extensions but you have to first type chrome://version/ in a tab and then look out for Profile path inside that and after you reach to your profile path look for Extensions folder in it and then folder with the desired extension Id

This maybe because the c compiler is designed to work in linux.I had this problem too and to fix it go to tools and select compiler options.In the box click on programs

Now you will see a tab with gcc and make and the respective path to it.Edit the gcc and make path to use mingw32-c++.exe and mingw32-make.exe respectively.Now it will work.

The reason was that you were using compilers built for linux.

A shorter way than using second parameter for the callback of collection.insert would be using objectToInsert._id that returns the _id (inside of the callback function, supposing it was a successful operation).

The Mongo driver for NodeJS appends the _id field to the original object reference, so it's easy to get the inserted id using the original object:

collection.insert(objectToInsert, function(err){
   if (err) return;
   // Object inserted successfully.
   var objectId = objectToInsert._id; // this will return the id of object inserted
});

FYI, if you want to print all the files in multi-line, you can do a ls -1 which will print each file in a separate line. file1 file2 file3

If you just want to make Apache run an don't mind which port it is running on, do the following:

In the XAMPP Control Panel, click on the Apache - 'Config' button which is located next to the 'Logs' button.

Select 'Apache (httpd.conf)' from the drop down. (notepad should open)

Do Ctrl + F to find '80'. Click 'find next' three times and change line Listen 80 to Listen 8080

Click 'find next' again a couple times until you see line ServerName localhost:80 change this to ServerName localhost:8080

Do Ctrl + S to save and then exit notepad.

Start up Apache again in the XAMPP Control Panel, Apache should successfully run.

Use http://localhost:8080/ in your browser address bar to check everything is working.

EDIT

Also you may have problems running XAMPP while running IIS. If you are running IIS it might be worth stopping the service then starting XAMPP.

I was able to resolve the issue by opening the script in Gedit and saving it with the proper Line Ending option:

File > Save As...

In the bottom left of the Save As prompt, there are drop-down menus for Character Encoding and Line Ending. Change the Line Ending from Windows to Unix/Linux then Save.

For me the error was quite simple based on what @alfred_m said..... tomcat had 2 jars conflicting having same set of Class names and configuration.

What happened was ..............I copied my existing project to make a new project out of the existing project. but without making required changes, I started working on other project. Henec 2 projects had same classes and configuration files, resulting into conflict.

Deleted the copied project and things started working!!!!

db.collection_name.aggregate([
    { '$match'    : { } },
    { '$sort'     : { '_id' : -1 } },
    { '$facet'    : {
        metadata: [ { $count: "total" } ],
        data: [ { $skip: 1 }, { $limit: 10 },{ '$project' : {"_id":0} } ] // add projection here wish you re-shape the docs
    } }
] )

Instead of using two queries to find the total count and skip the matched record.
$facet is the best and optimized way.

1. Match the record
   
2. Find total_count
   
3. skip the record
   
4. And also can reshape data according to our needs in the query.

team! For execute SQL-query from your Servlet you should add JDBC jar library in folder

WEB-INF/lib

After this you could call driver, example :

Class.forName("oracle.jdbc.OracleDriver");

Now Y can use connection to DB-server

to show some (previously computed) variable someVariable. Or run code that prints etc pp.

So for plotting, I have eg

### Impact of choice of ....
```{r somePlot, echo=FALSE}
plotResults(Res, Grid, "some text", "some more text")
```

where the plotting function plotResults is from a local package.

Error Handling:

You could try something like this to catch a specific error:

    On Error Resume Next
    Set owb = Application.Workbooks.Open(fpath & "\" & fname)
    If Err.Number = 1004 Then
    GoTo FileNotFound
    Else
    End If

    ...
    Exit Sub
    FileNotFound: If MsgBox("This File Does Not Exist!", vbRetryCancel) = vbCancel Then

    Else: Call Clear

Got same error in this line

 Object temp = range.Cells[i][0].Value;

Solved with non-zero based index

 Object temp = range.Cells[i][1].Value;

How is it possible that the guys who created this library thought it was a good idea to use non-zero based indexing?

Your Button2Click and Button3Click functions pass klad.xls and smimime.txt. These files most likely aren't actual executables indeed.

In order to open arbitrary files using the application associated with them, use ShellExecute

Similar problem wasted better half of my day!

Since solution for my problem was different from whats said here, I'm going to post it so it might help someone else.

Mine was a breakpoint. I had a "Break at function" breakpoint (i.e instead of pressing F9 on a code line, we create them using the breakpoints window) which is supposed to stop in a library function outside my project.

And I had "Use Intellisense to verify the function name" CHECKED. (Info here.)

This slowed down vs like hell (project start-up from 2 seconds to 5 minutes).

Removing the break point solved it for good.

I solved the same error with the Path.Combine(MapPath()) to get the physical file path instead of the http:/// www one.

So based on what you said, these files are libraries/documentation you don't want to delete but also don't want to push to github. Let say you have your project in folder your_project and a doc directory: your_project/doc.

1. Remove it from the project directory (without actually deleting it): git rm --cached doc/*
2. If you don't already have a .gitignore, you can make one right inside of your project folder: project/.gitignore.
3. Put doc/* in the .gitignore
4. Stage the file to commit: git add project/.gitignore
5. Commit: git commit -m "message".
6. Push your change to github.

It is the version key.It gets updated whenever a new update is made. I personally don't like to disable it .

After giving necessary permissions in DCOM configurations I also needed to change the identity of my application in the IIS to a custom account

Since you installed a new OS you probably don't have any more of your private and public keys that you used to sign your app in to XCode before. You need to regenerate those keys on your machine by revoking your previous certificate and asking for a new one on the iOS development portal. As part of the process you will be asked to generate a Certificate Signing Request which is where you seem to have a problem.

You will find all you need there which consists of (from the official doc):

1.Open Keychain Access on your Mac (located in Applications/Utilities).

2.Open Preferences and click Certificates. Make sure both Online Certificate Status Protocol and Certificate Revocation List are set to Off.

3.Choose Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority.

Note: If you have a private key selected when you do this, the CSR won’t be accepted. Make sure no private key is selected. Enter your user email address and common name. Use the same address and name as you used to register in the iOS Developer Program. No CA Email Address is required.

4.Select the options “Saved to disk” and “Let me specify key pair information” and click Continue.

5.Specify a filename and click Save. (make sure to replace .certSigningRequest with .csr)

For the Key Size choose 2048 bits and for Algorithm choose RSA. Click Continue and the Certificate Assistant creates a CSR and saves the file to your specified location.

Restarting Visual Studio solved the problem for me.

First off, if you want to extract count features and apply TF-IDF normalization and row-wise euclidean normalization you can do it in one operation with TfidfVectorizer:

>>> from sklearn.feature_extraction.text import TfidfVectorizer
>>> from sklearn.datasets import fetch_20newsgroups
>>> twenty = fetch_20newsgroups()

>>> tfidf = TfidfVectorizer().fit_transform(twenty.data)
>>> tfidf
<11314x130088 sparse matrix of type '<type 'numpy.float64'>'
    with 1787553 stored elements in Compressed Sparse Row format>

Now to find the cosine distances of one document (e.g. the first in the dataset) and all of the others you just need to compute the dot products of the first vector with all of the others as the tfidf vectors are already row-normalized.

As explained by Chris Clark in comments and here Cosine Similarity does not take into account the magnitude of the vectors. Row-normalised have a magnitude of 1 and so the Linear Kernel is sufficient to calculate the similarity values.

The scipy sparse matrix API is a bit weird (not as flexible as dense N-dimensional numpy arrays). To get the first vector you need to slice the matrix row-wise to get a submatrix with a single row:

>>> tfidf[0:1]
<1x130088 sparse matrix of type '<type 'numpy.float64'>'
    with 89 stored elements in Compressed Sparse Row format>

scikit-learn already provides pairwise metrics (a.k.a. kernels in machine learning parlance) that work for both dense and sparse representations of vector collections. In this case we need a dot product that is also known as the linear kernel:

>>> from sklearn.metrics.pairwise import linear_kernel
>>> cosine_similarities = linear_kernel(tfidf[0:1], tfidf).flatten()
>>> cosine_similarities
array([ 1.        ,  0.04405952,  0.11016969, ...,  0.04433602,
    0.04457106,  0.03293218])

Hence to find the top 5 related documents, we can use argsort and some negative array slicing (most related documents have highest cosine similarity values, hence at the end of the sorted indices array):

>>> related_docs_indices = cosine_similarities.argsort()[:-5:-1]
>>> related_docs_indices
array([    0,   958, 10576,  3277])
>>> cosine_similarities[related_docs_indices]
array([ 1.        ,  0.54967926,  0.32902194,  0.2825788 ])

The first result is a sanity check: we find the query document as the most similar document with a cosine similarity score of 1 which has the following text:

 I was wondering if anyone out there could enlighten me on this car I saw
the other day. It was a 2-door sports car, looked to be from the late 60s/
early 70s. It was called a Bricklin. The doors were really small. In addition,
the front bumper was separate from the rest of the body. This is
all I know. If anyone can tellme a model name, engine specs, years
of production, where this car is made, history, or whatever info you
have on this funky looking car, please e-mail.

Bricklins were manufactured in the 70s with engines from Ford. They are rather
odd looking with the encased front bumper. There aren't a lot of them around,
but Hemmings (Motor News) ususally has ten or so listed. Basically, they are a
performance Ford with new styling slapped on top.

There's no need to add space before closing quote if path doesn't contain trailing backslash, so following command should work:

robocopy "C:\Source Path" "C:\Destination Path" /option1 /option2...

But, following will not work:

robocopy "C:\Source Path\" "C:\Destination Path\" /option1 /option2...

This is due to the escaping issue that is described here:

The \ escape can cause problems with quoted directory paths that contain a trailing backslash because the closing quote " at the end of the line will be escaped \".

If you happened to run npm install command on Windows, first make sure you open your command prompt with Administration Privileges. That's what solved the issue for me.

You need to add:

#include <string>

In your header file.

Create Arraylist<Date> of Date class. And use Collections.sort() for ascending order.

See sort(List<T> list)

Sorts the specified list into ascending order, according to the natural ordering of its elements.

For Sort it in descending order See Collections.reverseOrder()

Collections.sort(yourList, Collections.reverseOrder());

All answers look a bit to big. I just use:

if (SYSTEM_VERSION_GREATER_THAN(@"7.0")){(..CODE...)}
if (SYSTEM_VERSION_EQUAL_TO(@"7.0")){(..CODE...)}
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")){(..CODE...)}
if (SYSTEM_VERSION_LESS_THAN(@"7.0")){(..CODE...)}
if (SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(@"7.0")){(..CODE...)}

Of course replace the @"7.0" with your required OS version.

From Laravel 5.7 with Illuminate\Database\Query\Builder you can use insertUsing method.

$query = [];
foreach($oXML->results->item->item as $oEntry){
    $date = date("Y-m-d H:i:s")
    $query[] = "('{$oEntry->firstname}', '{$oEntry->lastname}', '{$date}')";
}

Builder::insertUsing(['first_name', 'last_name', 'date_added'], implode(', ', $query));

I don't think this is possible using PostgreSQL alone in the most general case. When you install PostgreSQL, you pick a time zone. I'm pretty sure the default is to use the operating system's timezone. That will usually be reflected in postgresql.conf as the value of the parameter "timezone". But the value ends up as "localtime". You can see this setting with the SQL statement.

show timezone;

But if you change the timezone in postgresql.conf to something like "Europe/Berlin", then show timezone; will return that value instead of "localtime".

So I think your solution will involve setting "timezone" in postgresql.conf to an explicit value rather than the default "localtime".

I found it, I was trying to compile my app which is using facebook sdk. I was made that like augst 2016. When I try to open it today i got same error. I had that line in my gradle " compile 'com.facebook.android:facebook-android-sdk:4.+' " and I went https://developers.facebook.com/docs/android/change-log-4x this page and i found the sdk version while i was running this app succesfully and it was 4.14.1 then I changed that line to " compile 'com.facebook.android:facebook-android-sdk:4.14.1' " and it worked.

When creating a PWA, a service worker used on an non https server also generates this error.

We can break both a $(selector).each() loop and a $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.

return false; // this is equivalent of 'break' for jQuery loop

return;       // this is equivalent of 'continue' for jQuery loop

Note that $(selector).each() and $.each() are different functions.

Use GETDATE()

Returns the current database system timestamp as a datetime value without the database time zone offset. This value is derived from the operating system of the computer on which the instance of SQL Server is running.

UPDATE table SET date = GETDATE()

You can derive a class from Runnable, and during the construction (say) pass the parameter in.

Then launch it using Thread.start(Runnable r);

If you mean whilst the thread is running, then simply hold a reference to your derived object in the calling thread, and call the appropriate setter methods (synchronising where appropriate)

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

Regarding the printout, here's how I would do it using the Format Specification Mini Language (section: Aligning the text and specifying a width):

Once you have your length, say length = 11:

rowstring = '{{: ^{length:d}}}'.format(length = length) # center aligned, space-padded format string of length <length>
for i in xrange(length, 0, -2): # iterate from top to bottom with step size 2
    print rowstring.format( '*' * i )

Remove NodeJs and npm in your system and reinstall it by following commands

Uninlstallation

sudo apt remove nodejs
sudo apt remove npm

Fresh Installation

sudo apt install nodejs
sudo apt install npm

Configuration optional, in some cases users may face permission errors.

1. user defined directory where npm will install packages

   mkdir ~/.npm-global

2. configure npm

   npm config set prefix '~/.npm-global'

3. add directory to path

   echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.profile

4. refresh path for the current session

   source ~/.profile

5. cross-check npm and node modules installed successfully in our system

   node -v
npm -v

Installation of npx

sudo npm i -g npx
npx -v

Well-done we are ready to go... now you can easily use npx anywhere in your system.

The real problem of why you are getting the error is not that there is anything wrong with your code: you can use either iloc, loc, or apply, or *=, another of them could have worked.

The real problem that you have is due to how you created the df DataFrame. Most likely you created your df as a slice of another DataFrame without using .copy(). The correct way to create your df as a slice of another DataFrame is df = original_df.loc[some slicing].copy().

The problem is already stated in the error message you got " SettingWithCopyWarning: A value is trying to be set on a copy of a slice from a DataFrame. Try using .loc[row_indexer,col_indexer] = value instead"
You will get the same message in the most current version of pandas too.

Whenever you receive this kind of error message, you should always check how you created your DataFrame. Chances are you forgot the .copy()

There is no button type="cancel" in html. You can try like this

<a href="http://www.url.com/yourpage.php">Cancel</a>

You can make it look like a button by using CSS style properties.

Getting this error, I did a build with --info (gradle --info build). It reported that it could not open libz.so.1, due to wrong ELFCLASS. It needs a 32 bit version of libz. I had to download the source, change the Makefile to gcc -m32, and install the 32 bit glibc development package (dnf install glibc-devel.i686). After making and installing this 32 bit library, I disabled the 64 bit one.

Then all went well.

I will suppose your JPanel contains JTextField, for the sake of the demo.

Those components provides JTextComponent#setMargin() method which seems to be what you're looking for.

If you're looking for an empty border of any size around your text, well, use EmptyBorder

The reason for the error is that the nextInt only pulls the integer, not the newline. If you add a in.nextLine() before your for loop, it will eat the empty new line and allow you to enter 3 names.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = in.nextInt();

names = new String[nnames];
in.nextLine();
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

or just read the line and parse the value as an Integer.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = Integer.parseInt(in.nextLine().trim());

names = new String[nnames];
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

If your directory structure is like this,

site
  application
         controller
                folder_1
                   first_controller.php
                   second_controller.php
                folder_2
                   first_controller.php
                   second_controller.php

And when you are going to redirect it in same controller in which you are working then just write the following code.

 $this->load->helper('url');
    if ($some_value === FALSE/TRUE) //You may give 0/1 as well,its up to your logic
    {
         redirect('same_controller/method', 'refresh');
    }

And if you want to redirect to another control then use the following code.

$this->load->helper('url');
if ($some_value === FALSE/TRUE) //You may give 0/1 as well,its up to your logic
{
     redirect('folder_name/any_controller_name/method', 'refresh');
}

$('#tableId').on('draw.dt', function() {
    //This will get called when data table data gets redrawn to the      table.
});

You Can use EXTRACT function pgSQL

EX- date = 1981-05-31
EXTRACT(MONTH FROM date)
it will Give 05

For more details PGSQL Date-Time

An additional possible cause.

My HTML page had these starting tags:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">

This was on a page that using the slick jquery slideshow.

I removed the tags and replaced with:

<html>

And everything is working again.

__call__ is also used to implement decorator classes in python. In this case the instance of the class is called when the method with the decorator is called.

class EnterExitParam(object):

    def __init__(self, p1):
        self.p1 = p1

    def __call__(self, f):
        def new_f():
            print("Entering", f.__name__)
            print("p1=", self.p1)
            f()
            print("Leaving", f.__name__)
        return new_f


@EnterExitParam("foo bar")
def hello():
    print("Hello")


if __name__ == "__main__":
    hello()

program output:

Entering hello
p1= foo bar
Hello
Leaving hello

Remove everything before <?xml version="1.0" encoding="utf-8"?>

Sometimes, there is some "invisible" (not visible in all text editors). Some programs add this.

I have adapted the script from Russ Cam (thank you, Russ Cam!) to my own needs: I needed to merge any columns that had the same value, not just empty cells.

This could be useful to someone else... Here is what I have come up with:

jQuery(document).ready(function() {

   jQuery('table.tblSimpleAgenda tr').each(function() {
    var tr = this;
    var counter = 0;
    var strLookupText = '';

    jQuery('td', tr).each(function(index, value) {
      var td = jQuery(this);

      if ((td.text() == strLookupText) || (td.text() == "")) {
        counter++;
        td.prev().attr('colSpan', '' + parseInt(counter + 1,10) + '').css({textAlign : 'center'});
        td.remove();
      }
      else {
        counter = 0;
      }

      // Sets the strLookupText variable to hold the current value. The next time in the loop the system will check the current value against the previous value.
      strLookupText = td.text();

    });

  });

});

Although I agree with this answer, as it has fewer lines of code and that it works:

How to set menu to Toolbar in Android

My suggestion would be to always start any project using the Android Studio Wizard. In that code you will find some styles:-

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

and usage is:

<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">

<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />

</android.support.design.widget.AppBarLayout> 

Due to no action bar theme declared in styles.xml, that is applied to the Main Activityin the AndroidManifest.xml, there are no exceptions, so you have to check it there.

<activity android:name=".MainActivity" android:screenOrientation="portrait"
        android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

1. The Toolbar is not an independent entity, it is always a child view in AppBarLayout that again is the child of CoordinatorLayout.
2. The code for creating a menu is the standard code since day one, that is repeated again and again in all the answers, particularly the marked one, but nobody realized what is the difference.

BOTH:

Toolbar toolbar = findViewById(R.id.toolbar); setSupportActionBar(toolbar);

AND:

Happy Coding :-)

Here is a working example :

document.cookie = "testCookie=cookieval; domain=." + 
location.hostname.split('.').reverse()[1] + "." + 
location.hostname.split('.').reverse()[0] + "; path=/"

This is a generic solution that takes the root domain from the location object and sets the cookie. The reversing is because you don't know how many subdomains you have if any.

Use gradle dependencies to get the Gson in your project. Your application build.gradle should look like this-

dependencies {
  implementation 'com.google.code.gson:gson:2.8.2'
}

In the "Understanding Crashes and Crash Logs" session 414 of the 2018 WWDC they show the following way using DispatchQueues with sync.

In swift 4 should be something like the following:

class ImageCache {
    private let queue = DispatchQueue(label: "sync queue")
    private var storage: [String: UIImage] = [:]
    public subscript(key: String) -> UIImage? {
        get {
          return queue.sync {
            return storage[key]
          }
        }
        set {
          queue.sync {
            storage[key] = newValue
          }
        }
    }
}

Anyway you can also make reads faster using concurrent queues with barriers. Sync and async reads are performed concurrently and writing a new value waits for previous operations to finish.

class ImageCache {
    private let queue = DispatchQueue(label: "with barriers", attributes: .concurrent)
    private var storage: [String: UIImage] = [:]

    func get(_ key: String) -> UIImage? {
        return queue.sync { [weak self] in
            guard let self = self else { return nil }
            return self.storage[key]
        }
    }

    func set(_ image: UIImage, for key: String) {
        queue.async(flags: .barrier) { [weak self] in
            guard let self = self else { return }
            self.storage[key] = image
        }
    }
}

Not sure about the (errors="ignore") option but it seems to work for files with strange Unicode characters.

with open(fName, "rb") as fData:
    lines = fData.read().splitlines()
    lines = [line.decode("utf-8", errors="ignore") for line in lines]

You can pass the inline handler the this keyword, obtaining the element which fired the event.

like,

onclick="confirmSubmit(this);"

The z-index property only works on elements with a position value other than static (e.g. position: absolute;, position: relative;, or position: fixed).

There is also position: sticky; that is supported in Firefox, is prefixed in Safari, worked for a time in older versions of Chrome under a custom flag, and is under consideration by Microsoft to add to their Edge browser.

Important
For regular positioning, be sure to include position: relative on the elements where you also set the z-index. Otherwise, it won't take effect.

Here's a good tutorial on what crontab is and how to use it on Ubuntu. Your crontab line will look something like this:

00 00 * * * ruby path/to/your/script.rb

(00 00 indicates midnight--0 minutes and 0 hours--and the *s mean every day of every month.)

Syntax: 
  mm hh dd mt wd  command

  mm minute 0-59
  hh hour 0-23
  dd day of month 1-31
  mt month 1-12
  wd day of week 0-7 (Sunday = 0 or 7)

There are a few operations you can only do with DI/SI (or their extended counterparts, if you didn't learn ASM in 1985). Among these are

REP STOSB
REP MOVSB
REP SCASB

Which are, respectively, operations for repeated (= mass) storing, loading and scanning. What you do is you set up SI and/or DI to point at one or both operands, perhaps put a count in CX and then let 'er rip. These are operations that work on a bunch of bytes at a time, and they kind of put the CPU in automatic. Because you're not explicitly coding loops, they do their thing more efficiently (usually) than a hand-coded loop.

Just in case you're wondering: Depending on how you set the operation up, repeated storing can be something simple like punching the value 0 into a large contiguous block of memory; MOVSB is used, I think, to copy data from one buffer (well, any bunch of bytes) to another; and SCASB is used to look for a byte that matches some search criterion (I'm not sure if it's only searching on equality, or what – you can look it up :) )

That's most of what those regs are for.

This was my solution with BOOST:

#include <boost/preprocessor.hpp>

#define X_STR_ENUM_TOSTRING_CASE(r, data, elem)                                 \
    case elem : return BOOST_PP_STRINGIZE(elem);

#define X_ENUM_STR_TOENUM_IF(r, data, elem)                                     \
    else if(data == BOOST_PP_STRINGIZE(elem)) return elem;

#define STR_ENUM(name, enumerators)                                             \
    enum name {                                                                 \
        BOOST_PP_SEQ_ENUM(enumerators)                                          \
    };                                                                          \

To create enum, declare:

STR_ENUM
(
    SERVICE_RELOAD,
        (reload_log)
        (reload_settings)
        (reload_qxml_server)
)

For conversions:

SERVICE_RELOAD serviceReloadEnum = strToEnum<SERVICE_RELOAD>("reload_log");
QString serviceReloadStr = enumToStr(reload_log);

If your markup is bound to a controller, directive or anything else with a $scope:

console.log($scope.movie);

Have you instaled the J2EE? If you installed just de standard (J2SE) it won´t find.

IF your data won't overflow 4000 characters AND you're on SQL Server 2000 or compatibility level of 8 or SQL Server 2000:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(4000)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

For SQL Server 2005+:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(MAX)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

Since 2017 Wikipedia provides a REST API with better caching. In the documentation you can find the following API which perfectly fits your use case. (as it is used by the new Page Previews feature)

https://en.wikipedia.org/api/rest_v1/page/summary/Stack_Overflow returns the following data which can be used to display a summery with a small thumbnail:

By default, it follows redirects (so that /api/rest_v1/page/summary/StackOverflow also works), but this can be disabled with ?redirect=false

If you need to access the API from another domain you can set the CORS header with &origin= (e.g. &origin=*)

Update 2019: The API seems to return more useful information about the page.

In my case eighter git rebase --abort and git rebase --continue was throwing:

error: could not read '.git/rebase-apply/head-name': No such file or directory

I managed to fix this issue by manually removing: .git\rebase-apply directory.

You can also do this with one query too using a join like so:

UPDATE table1,table2 SET table1.col=a,table2.col2=b
WHERE items.id=month.id;

And then just send this one query, of course. You can read more about joins here: http://dev.mysql.com/doc/refman/5.0/en/join.html. There's also a couple restrictions for ordering and limiting on multiple table updates you can read about here: http://dev.mysql.com/doc/refman/5.0/en/update.html (just ctrl+f "join").

The simplest solution is :

    listView.setTranscriptMode(ListView.TRANSCRIPT_MODE_ALWAYS_SCROLL);
    listView.setStackFromBottom(true);

printStackTrace is a method of the Throwable class. This method displays error message in the console; where we are getting the exception in the source code. These methods can be used with catch block and they describe:

1. Name of the exception.
2. Description of the exception.
3. Location of the exception in the source code.

The three methods which describe the exception on the console (in which printStackTrace is one of them) are:

1. printStackTrace()
2. toString()
3. getMessage()

Example:

public class BabluGope {
    public static void main(String[] args) {
        try {
            System.out.println(10/0);
         } catch (ArithmeticException e) {
             e.printStackTrace();   
             // System.err.println(e.toString());
             //System.err.println(e.getMessage());  
         }
    }
}

In plain vanilla JavaScript, with no libraries? It's an error. $ is simply an identifier, and is undefined unless you define it.

jQuery defines $ as it's own "everything object" (also known as jQuery so you can use it without conflicting with other libraries). If you're not using jQuery (or some other library that defines it), then $ will not be defined.

Or are you asking what the equivalent is in plain JavaScript? In that case, you probably want window.onload, which isn't exactly equivalent, but is the quickest and easiest way to get close to the same effect in vanilla JavaScript.

I came up with this function, which basically behaves similarly to one in the answer by Alex:

-(NSString*)trimLastSpace:(NSString*)str{
    int i = str.length - 1;
    for (; i >= 0 && [str characterAtIndex:i] == ' '; i--);
    return [str substringToIndex:i + 1];
}

whitespaceCharacterSet besides space itself includes also tab character, which in my case could not appear. So i guess a plain comparison could suffice.

- name: set pkg copy dir name
  set_fact:
    PKG_DIR: >-
      {% if ansible_os_family == "RedHat" %}centos/*.rpm
      {%- elif ansible_distribution == "Ubuntu" %}ubuntu/*.deb
      {%- elif ansible_distribution == "Kylin Linux Advanced Server" %}kylin/*.deb
      {%- else %}{%- endif %}

While you can't add a wildcard like that, you could add the full list of sites that you need, at least for testing, that works well enough for me, in your hosts file, you just add:

127.0.0.1 site1.local
127.0.0.1 site2.local
127.0.0.1 site3.local
...

You have an error in you script tag construction, this:

<script language="JavaScript" type="text/javascript" script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js"></script>

Should look like this:

<script language="JavaScript" type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.0/jquery-ui.min.js"></script>

You have a 'script' word lost in the middle of your script tag. Also you should remove the http:// to let the browser decide whether to use HTTP or HTTPS.

UPDATE

But your main error is that you are including jQuery UI (ONLY) you must include jQuery first! jQuery UI and jQuery are used together, not in separate. jQuery UI depends on jQuery. You should put this line before jQuery UI:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>

I just deleted the file from within VS, then from 'Repository Explorer', I copied the file to the working copy.

You can do it with a pivot query, like this:

select * from (
   select LOAN_NUMBER, DOCUMENT_TYPE, DOCUMENT_ID
   from my_table t
)
pivot 
(
   MIN(DOCUMENT_ID)
   for DOCUMENT_TYPE in ('Voters ID','Pan card','Drivers licence')
)

Here is a demo on sqlfiddle.com.

use value instead of query (must specify index of node to return in the XQuery as well as passing the sql data type to return as the second parameter):

select
    xt.Id
    , x.m.value( '@id[1]', 'varchar(max)' ) MetricId
from
    XmlTest xt
    cross apply xt.XmlData.nodes( '/Sqm/Metrics/Metric' ) x(m)

You can set the fraction of GPU memory to be allocated when you construct a tf.Session by passing a tf.GPUOptions as part of the optional config argument:

# Assume that you have 12GB of GPU memory and want to allocate ~4GB:
gpu_options = tf.GPUOptions(per_process_gpu_memory_fraction=0.333)

sess = tf.Session(config=tf.ConfigProto(gpu_options=gpu_options))

The per_process_gpu_memory_fraction acts as a hard upper bound on the amount of GPU memory that will be used by the process on each GPU on the same machine. Currently, this fraction is applied uniformly to all of the GPUs on the same machine; there is no way to set this on a per-GPU basis.

For not very sharp eyes like mine, I had href instead of routerLink, took me a few searches to figure that out #facepalm.

1. Create an external table
2. Insert data into the table
3. Optional drop the table later, which wont delete that file since it is an external table

Example:

Creating external table to store the query results at '/user/myName/projectA_additionaData/'

CREATE EXTERNAL TABLE additionaData
(
     ID INT,
     latitude STRING,
     longitude STRING
)
COMMENT 'Additional Data gathered by joining of the identified cities with latitude and longitude data' 
ROW FORMAT DELIMITED FIELDS
TERMINATED BY ',' STORED AS TEXTFILE location '/user/myName/projectA_additionaData/';

Feeding the query results into the temp table

 insert into additionaData 
     Select T.ID, C.latitude, C.longitude 
     from TWITER  
     join CITY C on (T.location_name = C.location);

Dropping the temp table

drop table additionaData

There are various ways to achieve this. Here are three.

    Map<String, String> map = new HashMap<String, String>();
    map.put("key1", "value1");
    map.put("key2", "value2");
    map.put("key3", "value3");

    System.out.println("using entrySet and toString");
    for (Entry<String, String> entry : map.entrySet()) {
        System.out.println(entry);
    }
    System.out.println();

    System.out.println("using entrySet and manual string creation");
    for (Entry<String, String> entry : map.entrySet()) {
        System.out.println(entry.getKey() + "=" + entry.getValue());
    }
    System.out.println();

    System.out.println("using keySet");
    for (String key : map.keySet()) {
        System.out.println(key + "=" + map.get(key));
    }
    System.out.println();

Output

using entrySet and toString
key1=value1
key2=value2
key3=value3

using entrySet and manual string creation
key1=value1
key2=value2
key3=value3

using keySet
key1=value1
key2=value2
key3=value3

First, keep in mind that, in its precise definition, a module is an object in the memory of a Python interpreter, often created by reading one or more files from disk. While we may informally call a disk file such as a/b/c.py a "module," it doesn't actually become one until it's combined with information from several other sources (such as sys.path) to create the module object.

(Note, for example, that two modules with different names can be loaded from the same file, depending on sys.path and other settings. This is exactly what happens with python -m my.module followed by an import my.module in the interpreter; there will be two module objects, __main__ and my.module, both created from the same file on disk, my/module.py.)

A package is a module that may have submodules (including subpackages). Not all modules can do this. As an example, create a small module hierarchy:

$ mkdir -p a/b
$ touch a/b/c.py

Ensure that there are no other files under a. Start a Python 3.4 or later interpreter (e.g., with python3 -i) and examine the results of the following statements:

import a
a                ? <module 'a' (namespace)>
a.b              ? AttributeError: module 'a' has no attribute 'b'
import a.b.c
a.b              ? <module 'a.b' (namespace)>
a.b.c            ? <module 'a.b.c' from '/home/cjs/a/b/c.py'>

Modules a and a.b are packages (in fact, a certain kind of package called a "namespace package," though we wont' worry about that here). However, module a.b.c is not a package. We can demonstrate this by adding another file, a/b.py to the directory structure above and starting a fresh interpreter:

import a.b.c
? ImportError: No module named 'a.b.c'; 'a.b' is not a package
import a.b
a                ? <module 'a' (namespace)>
a.__path__       ? _NamespacePath(['/.../a'])
a.b              ? <module 'a.b' from '/home/cjs/tmp/a/b.py'>
a.b.__path__     ? AttributeError: 'module' object has no attribute '__path__'

Python ensures that all parent modules are loaded before a child module is loaded. Above it finds that a/ is a directory, and so creates a namespace package a, and that a/b.py is a Python source file which it loads and uses to create a (non-package) module a.b. At this point you cannot have a module a.b.c because a.b is not a package, and thus cannot have submodules.

You can also see here that the package module a has a __path__ attribute (packages must have this) but the non-package module a.b does not.

Dude I know totally how you feel, but don't forget about inline styling. It is almost the super saiyan of the CSS specificity

So it should look something like this for you,

<span class="icon-bar" style="background-color: black !important;">
</span>
<span class="icon-bar" style="background-color: black !important;">
</span>
<span class="icon-bar" style="background-color: black !important;">
</span>

Firstly run this query

SHOW VARIABLES LIKE '%char%';

You have character_set_server='latin1'

for eg if CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci replace it to CHARSET=latin1 and remove the collate

You are good to go

One addition to @Omid Ariyan's answer is permissions on directories. Add this after the for loop's done in his pre-commit script.

for DIR in $(find ./ -mindepth 1 -type d -not -path "./.git" -not -path "./.git/*" | sed 's@^\./@@')
do
    # Save the permissions of all the files in the index
    echo $DIR";"`stat -c "%a;%U;%G" $DIR` >> $DATABASE
done

This will save directory permissions as well.

You can use JSON.stringify(object) with an object and I just wrote a function that'll recursively convert an array to an object, like this JSON.stringify(convArrToObj(array)), which is the following code (more detail can be found on this answer):

// Convert array to object
var convArrToObj = function(array){
    var thisEleObj = new Object();
    if(typeof array == "object"){
        for(var i in array){
            var thisEle = convArrToObj(array[i]);
            thisEleObj[i] = thisEle;
        }
    }else {
        thisEleObj = array;
    }
    return thisEleObj;
}

To make it more generic, you can override the JSON.stringify function and you won't have to worry about it again, to do this, just paste this at the top of your page:

// Modify JSON.stringify to allow recursive and single-level arrays
(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        return oldJSONStringify(convArrToObj(input));
    };
})();

And now JSON.stringify will accept arrays or objects! (link to jsFiddle with example)

Edit:

Here's another version that's a tad bit more efficient, although it may or may not be less reliable (not sure -- it depends on if JSON.stringify(array) always returns [], which I don't see much reason why it wouldn't, so this function should be better as it does a little less work when you use JSON.stringify with an object):

(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        if(oldJSONStringify(input) == '[]')
            return oldJSONStringify(convArrToObj(input));
        else
            return oldJSONStringify(input);
    };
})();

js Performance test here, via jsPerf

set global sql_mode="NO_BACKSLASH_ESCAPES,STRICT_TRANS_TABLE,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

No need to jump through hoops. Subtracting Start from End essentially gives you the timespan (combining Vignesh Kumar's and Carl Nitzsche's answers) :

SELECT *,
    --as a time object
    TotalHours = CONVERT(time, EndDate - StartDate),
    --as a formatted string
    TotalHoursText = CONVERT(varchar(20), EndDate - StartDate, 114)
FROM (
    --some test values (across days, but OP only cares about the time, not date)
    SELECT
        StartDate = CONVERT(datetime,'20090213 02:44:37.923'),
        EndDate   = CONVERT(datetime,'20090715 13:24:45.837')
) t

Ouput

StartDate               EndDate                 TotalHours       TotalHoursText
----------------------- ----------------------- ---------------- --------------------

This works with all objects and arrays :)

ex:

if( obj._has( "something.['deep']['under'][1][0].item" ) ) {
    //do something
}

this is my improved version of Brian's answer

I used _has as the property name because it can conflict with existing has property (ex: maps)

Object.defineProperty( Object.prototype, "_has", { value: function( needle ) {
var obj = this;
var needles = needle.split( "." );
var needles_full=[];
var needles_square;
for( var i = 0; i<needles.length; i++ ) {
    needles_square = needles[i].split( "[" );
    if(needles_square.length>1){
        for( var j = 0; j<needles_square.length; j++ ) {
            if(needles_square[j].length){
                needles_full.push(needles_square[j]);
            }
        }
    }else{
        needles_full.push(needles[i]);
    }
}
for( var i = 0; i<needles_full.length; i++ ) {
    var res = needles_full[i].match(/^((\d+)|"(.+)"|'(.+)')\]$/);
    if (res != null) {
        for (var j = 0; j < res.length; j++) {
            if (res[j] != undefined) {
                needles_full[i] = res[j];
            }
        }
    }

    if( typeof obj[needles_full[i]]=='undefined') {
        return false;
    }
    obj = obj[needles_full[i]];
}
return true;
}});

Here's the fiddle

This worked for me as well:

Get-ADUser -Filter * -SearchBase "ou=OU,dc=Domain,dc=com" -Properties Enabled, CanonicalName, Displayname, Givenname, Surname, EmployeeNumber, EmailAddress, Department, StreetAddress, Title | select Enabled, CanonicalName, Displayname, GivenName, Surname, EmployeeNumber, EmailAddress, Department, Title | Export-CSV "C:\output.csv"

This often happens when you modify a c function definition and forget to update the corresponding header definition.

Here is how to create the desired outcome:

library(reshape2); library(tidyverse)
melt(outer(1:4, 1:4), varnames = c("X1", "X2")) %>%
ggplot() + 
  geom_tile(aes(X1, X2, fill = value)) + 
  scale_fill_continuous(guide = guide_legend()) +
  theme(legend.position="bottom",
        legend.spacing.x = unit(0, 'cm'))+
  guides(fill = guide_legend(label.position = "bottom"))

^{Created on 2019-12-07 by the reprex package (v0.3.0)}

Edit: no need for these imperfect options anymore, but I'm leaving them here for reference.

Two imperfect options that don't give you exactly what you were asking for, but pretty close (will at least put the colours together).

library(reshape2); library(tidyverse)
df <- melt(outer(1:4, 1:4), varnames = c("X1", "X2"))
p1 <- ggplot(df, aes(X1, X2)) + geom_tile(aes(fill = value))
p1 + scale_fill_continuous(guide = guide_legend()) +
 theme(legend.position="bottom", legend.direction="vertical")

p1 + scale_fill_continuous(guide = "colorbar") + theme(legend.position="bottom")

^{Created on 2019-02-28 by the reprex package (v0.2.1)}

Those two requires aren't equivalent. The equivalent version of the first one would be:

SELECT sum(numbackends) FROM pg_stat_database;

In that case, I would expect that version to be slightly faster than the second one, simply because it has fewer rows to count. But you are not likely going to be able to measure a difference.

Both queries are based on exactly the same data, so they will be equally accurate.

var values = new int[] {5,7,3};
var sortedValues = values.OrderBy(v => v).ToList();   // result 3,5,7

If you are working on Root Directory then you can use this approach

res.sendFile(__dirname + '/FOLDER_IN_ROOT_DIRECTORY/index.html');

but if you are using Routes which is inside a folder lets say /Routes/someRoute.js then you will need to do something like this

const path = require("path");
...
route.get("/some_route", (req, res) => {
   res.sendFile(path.resolve('FOLDER_IN_ROOT_DIRECTORY/index.html')
});

Another alternative is dotnetprojects SVGImage

This allows native use of .svg files directly in xaml.

The nice part is, it is only one assembly which is about 100k. In comparision to sharpvectors which is much bigger any many files.

Usage:

...
xmlns:svg1="clr-namespace:SVGImage.SVG;assembly=DotNetProjects.SVGImage"
...
<svg1:SVGImage Name="mySVGImage" Source="/MyDemoApp;component/Resources/MyImage.svg"/>
...

That's all.

See:

• https://www.nuget.org/packages/DotNetProjects.SVGImage/
• https://github.com/dotnetprojects/SVGImage

If you bother creating a sample project and adding your 3rd party dependency to that, then you can run the following in order to see the full hierarchy of the dependencies.

You can search for a specific artifact using this maven command:

mvn dependency:tree -Dverbose -Dincludes=[groupId]:[artifactId]:[type]:[version]

According to the documentation:

where each pattern segment is optional and supports full and partial * wildcards. An empty pattern segment is treated as an implicit wildcard.

Imagine you are trying to find 'log4j-1.2-api' jar file among different modules of your project:

mvn dependency:tree -Dverbose -Dincludes=org.apache.logging.log4j:log4j-1.2-api

more information can be found here.

Edit: Please note that despite the advantages of using verbose parameter, it might not be so accurate in some conditions. Because it uses Maven 2 algorithm and may give wrong results when used with Maven 3.

placeholders= ', '.join("'{"+str(i)+"}'" for i in range(len(l)))
query="select name from students where id (%s)"%placeholders
query=query.format(*l)
cursor.execute(query)

This should solve your problem.

In my case, where the timezones are not available on the server, this works great:

SELECT CONVERT_TZ(`date_field`,'+00:00',@@global.time_zone) FROM `table`

Note: global.time_zone uses the server timezone. You have to make sure, that it has the desired timezone!

You could use jquery.url I did like this:

var xyz = jQuery.url.param("param_in_url");

Check the source code

You may translate canvas by half-pixel distance.

ctx.translate(0.5, 0.5);

Initially the canvas positioning point between the physical pixels.

I believe you need quotes around the model:

JSON.stringify({ "model": source })

Display GIF file in android

Add the following dependency in your build.gradle file.

implementation 'pl.droidsonroids.gif:android-gif-drawable:1.2.0'

In the layout - activity_xxxxx.xml file add the GifImageview as below.

<pl.droidsonroids.gif.GifImageView
   android:id="@+id/CorrWrong"
   android:layout_width="100dp"
  android:layout_height="75dp"/>

In your Java file , u can access the gif as below.

 GifImageView emoji;
 emoji = (GifImageView)findViewById(R.id.CorrWrong);

Not jQuery, as the question asks for, but natively (i.e., no libraries required) I think the better tool for the job is querySelector to get a single instance of a selector:

let el = document.querySelector('img');
console.log(el);

For all matching instances, use document.querySelectorAll(), or for those within another element you can chain as follows:

// Get some wrapper, with class="parentClassName"
let parentEl = document.querySelector('.parentClassName');
// Get all img tags within the parent element by parentEl variable
let childrenEls = parentEl.querySelectorAll('img');

Note the above is equivalent to:

let childrenEls = document.querySelector('.parentClassName').querySelectorAll('img');

in the below method:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if (([array count]*65) > [UIScreen mainScreen].bounds.size.height - 66)
    {
        Table.frame = CGRectMake(0, 66, self.view.frame.size.width, [array count]*65)); 
    }
    else
    {
        Table.frame = CGRectMake(0, 66, self.view.frame.size.width, [UIScreen mainScreen].bounds.size.height - 66);
    }
    return [array count];
}

here 65 is the height of the cell and 66 is the height of the navigation bar in UIViewController.

This works for me with simple CSS properties:

.container {
    -ms-overflow-style: none;  /* Internet Explorer 10+ */
    scrollbar-width: none;  /* Firefox */
}
.container::-webkit-scrollbar { 
    display: none;  /* Safari and Chrome */
}

For older versions of Firefox, use: overflow: -moz-scrollbars-none;

It is worth trying these 2 options below while we're still waiting for the fix in FF35:

select {
    -moz-appearance: scrollbartrack-vertical;
}

or

select {
    -moz-appearance: treeview;
}

They will just hide any arrow background image you have put in to custom style your select element. So you get a bog standard browser arrow instead of a horrible combo of both browser arrow and your own custom arrow.

The first regex will match one whitespace character. The second regex will reluctantly match one or more whitespace characters. For most purposes, these two regexes are very similar, except in the second case, the regex can match more of the string, if it prevents the regex match from failing.  from http://www.coderanch.com/t/570917/java/java/regex-difference

for me, this solution didn't worked on a command exec with find, don't really know why, so my solution is

find . -type f -path "./a/*" -prune -o -path "./b/*" -prune -o -exec gzip -f -v {} \;

Explanation: same as sampson-chen one with the additions of

-prune - ignore the proceding path of ...

-o - Then if no match print the results, (prune the directories and print the remaining results)

18:12 $ mkdir a b c d e
18:13 $ touch a/1 b/2 c/3 d/4 e/5 e/a e/b
18:13 $ find . -type f -path "./a/*" -prune -o -path "./b/*" -prune -o -exec gzip -f -v {} \;

gzip: . is a directory -- ignored
gzip: ./a is a directory -- ignored
gzip: ./b is a directory -- ignored
gzip: ./c is a directory -- ignored
./c/3:    0.0% -- replaced with ./c/3.gz
gzip: ./d is a directory -- ignored
./d/4:    0.0% -- replaced with ./d/4.gz
gzip: ./e is a directory -- ignored
./e/5:    0.0% -- replaced with ./e/5.gz
./e/a:    0.0% -- replaced with ./e/a.gz
./e/b:    0.0% -- replaced with ./e/b.gz

Swift 4.1 introduces new -Osize optimization mode.

In Swift 4.1 the compiler now supports a new optimization mode which enables dedicated optimizations to reduce code size.

The Swift compiler comes with powerful optimizations. When compiling with -O the compiler tries to transform the code so that it executes with maximum performance. However, this improvement in runtime performance can sometimes come with a tradeoff of increased code size. With the new -Osize optimization mode the user has the choice to compile for minimal code size rather than for maximum speed.

To enable the size optimization mode on the command line, use -Osize instead of -O.

You can create the required headers in a filter too.

@WebFilter(urlPatterns="/rest/*")
public class AllowAccessFilter implements Filter {
    @Override
    public void doFilter(ServletRequest sRequest, ServletResponse sResponse, FilterChain chain) throws IOException, ServletException {
        System.out.println("in AllowAccessFilter.doFilter");
        HttpServletRequest request = (HttpServletRequest)sRequest;
        HttpServletResponse response = (HttpServletResponse)sResponse;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "GET, POST, PUT");
        response.setHeader("Access-Control-Allow-Headers", "Content-Type"); 
        chain.doFilter(request, response);
    }
    ...
}

What you need is the function strftime:

Time.now.strftime("%Y-%d-%m %H:%M:%S %Z")

For iOS 4.2 I had to go and create the 100APPLE folder and restart the simulator, then it worked.

You can also use echo to remove blank spaces, either at the beginning or at the end of the string, but also repeating spaces inside the string.

$ myVar="    kokor    iiij     ook      "
$ echo "$myVar"
    kokor    iiij     ook      
$ myVar=`echo $myVar`
$
$ # myVar is not set to "kokor iiij ook"
$ echo "$myVar"
kokor iiij ook

Follow this:

       List<string> name = new List<string>();   

        name.Add("Latif");

        name.Add("Ram");

        name.Add("Adam");
        string nameOfString = (string.Join(",", name.Select(x => x.ToString()).ToArray()));

Cross-Origin Read Blocking (CORB), an algorithm by which dubious cross-origin resource loads may be identified and blocked by web browsers before they reach the web page..It is designed to prevent the browser from delivering certain cross-origin network responses to a web page.

First Make sure these resources are served with a correct "Content-Type", i.e, for JSON MIME type - "text/json", "application/json", HTML MIME type - "text/html".

Second: set mode to cors i.e, mode:cors

The fetch would look something like this

 fetch("https://example.com/api/request", {
            method: 'POST',
            body: JSON.stringify(data),
            mode: 'cors',
            headers: {
                'Content-Type': 'application/json',
                "Accept": 'application/json',
            }
        })
    .then((data) => data.json())
    .then((resp) => console.log(resp))
    .catch((err) => console.log(err))

Here is another way:

df['rnd'] = np.random.rand(len(df)) df = df.sort_values(by='rnd', inplace=True).drop('rnd', axis=1)

Summarizing:

a = 3
b = a
a = 3+2
print b
# 5

Not immutable:

a = 'OOP'
b = a
a = 'p'+a
print b
# OOP

Immutable:

a = [1,2,3]
b = range(len(a))
for i in range(len(a)):
    b[i] = a[i]+1

This is an error in Python 3 because it is immutable. And not an error in Python 2 because clearly it is not immutable.

Make sure Match Case is selected with Use Regular Expression so this matches. [A-Z]* If match case is not selected, this matches all letters.

I would suggest the use of MySQLi or MySQL PDO for performance and security purposes, but to answer the question:

while($row = mysql_fetch_assoc($result)){
     $json[] = $row;
}

echo json_encode($json);

If you switched to MySQLi you could do:

$query = "SELECT * FROM table";
$result = mysqli_query($db, $query);

$json = mysqli_fetch_all ($result, MYSQLI_ASSOC);
echo json_encode($json );

If you have a list of column names in data.table, you want to change the class of do:

convert_to_character <- c("Quarter", "value")

dt[, convert_to_character] <- dt[, lapply(.SD, as.character), .SDcols = convert_to_character]

Late to the party. I'm on Windows 10 with JDK 1.8 and Eclipse MARS 1.
I find that

getClass().getClassLoader().getResourceAsStream("path/to/resource");

works and

getClass().getClassLoader().getResourceAsStream("path"+File.separator+"to"+File.separator+"resource");

does not work and

getClass().getClassLoader().getResourceAsStream("path\to\resource");

does not work. The last two are equivalent. So... I have good reason to NOT use File.separator.

The permament pool contains everything that is not your application data, but rather things required for the VM: typically it contains interned strings, the byte code of defined classes, but also other "not yours" pieces of data.

• Just for another example of Scanner.next() and nextLine() is that like below : nextLine() does not let user type while next() makes Scanner wait and read the input.

The only information currently available is that Apple Pay will be available in ios8, but that doesn't shed any light on whether RFID tags or rather NFC tags specifically will be able to be detected/read.

IMO it would be a shortsighted move not to allow that possibility, but really the money is in Apple Pay, not necessarily in allowing developers access to those features - we've seen it before with tethering, Bluetooth SPP, and diminished access to certain functions.

3. Then use the line numbers to replace start-of-line with "#", how?

:35,77s/^/#/

Note: the numbers are inclusive, lines from 35 to 77, both included will be modified.

To uncomment/undo that, simply use :35,77s/^#//

If you want to add a text word as a comment after every line of code, you can also use:

:35,77s/$/#test/ (for languages like Python)

:35,77s/;$/;\/\/test/ (for languages like Java)

For a console application you can use System.Reflection.Assembly.GetExecutingAssembly().Location as long as the call is made within the code of the console app itself, if you call this from within another dll or plugin this will return the location of that DLL and not the executable.

If you know what class the field is on you can access it using reflection. This example (it's in Groovy but the method calls are identical) gets a Field object for the class Foo and gets its value for the object b. It shows that you don't have to care about the exact concrete class of the object, what matters is that you know the class the field is on and that that class is either the concrete class or a superclass of the object.

groovy:000> class Foo { def stuff = "asdf"}
===> true
groovy:000> class Bar extends Foo {}
===> true
groovy:000> b = new Bar()
===> Bar@1f2be27
groovy:000> f = Foo.class.getDeclaredField('stuff')
===> private java.lang.Object Foo.stuff
groovy:000> f.getClass()
===> class java.lang.reflect.Field
groovy:000> f.setAccessible(true)
===> null
groovy:000> f.get(b)
===> asdf

In your Controller

public function updtitle() 
{   
    $data = array(
        'table_name' => 'your_table_name_to_update', // pass the real table name
        'id' => $this->input->post('id'),
        'title' => $this->input->post('title')
    );

    $this->load->model('Updmodel'); // load the model first
    if($this->Updmodel->upddata($data)) // call the method from the model
    {
        // update successful
    }
    else
    {
        // update not successful
    }

}

In Your Model

public function upddata($data) {
    extract($data);
    $this->db->where('emp_no', $id);
    $this->db->update($table_name, array('title' => $title));
    return true;
}

The active record query is similar to

"update $table_name set title='$title' where emp_no=$id"

you should use "bAutoWidth" property of datatable and give width to each td/column in %

 $(".table").dataTable({"bAutoWidth": false , 
aoColumns : [
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "15%"},
      { "sWidth": "10%"},
    ]
});

Hope this will help.

As explained on another answer using pandas.DataFrame() directly here will not act as you think.

What you can do is use pandas.DataFrame.from_dict with orient='index':

In[7]: pandas.DataFrame.from_dict({u'2012-06-08': 388,
 u'2012-06-09': 388,
 u'2012-06-10': 388,
 u'2012-06-11': 389,
 u'2012-06-12': 389,
 .....
 u'2012-07-05': 392,
 u'2012-07-06': 392}, orient='index', columns=['foo'])
Out[7]: 
            foo
2012-06-08  388
2012-06-09  388
2012-06-10  388
2012-06-11  389
2012-06-12  389
........
2012-07-05  392

The file you give is a shell script, not an awk program. So, try sh my.awk.

If you want to use awk -f my.awk life.csv > life_out.cs, then remove awk -F , ' and the last line from the file and add FS="," in BEGIN.

It's easier for me to think in these terms, but borrowing from other answers. The value you want is located in the series:

df[*column*][*row*]

where column and row point to the value you want returned. For your example, column is 'A' and for row you use a mask:

df['B'] == 3

To get the value from the series there are several options:

df['A'][df['B'] == 3].values[0]
df['A'][df['B'] == 3].iloc[0]
df['A'][df['B'] == 3].to_numpy()[0]

I had the problem that I wanted to use my ViewBag to send a list of elements through a RenderPartial as the object, and to this you have to do the cast first, I had to cast the ViewBag in the controller and in the View too.

In the Controller:

ViewBag.visitList = (List<CLIENTES_VIP_DB.VISITAS.VISITA>)                                                                 
visitaRepo.ObtenerLista().Where(m => m.Id_Contacto == id).ToList()

In the View:

List<CLIENTES_VIP_DB.VISITAS.VISITA> VisitaList = (List<CLIENTES_VIP_DB.VISITAS.VISITA>)ViewBag.visitList ;

Well, here is my "answer". It uses the fact that String.Split can be told hold many items it should split to (which I found lacking in the other answers):

string theString = "Some Very Large String Here";
var array = theString.Split(new [] { ' ' }, 2); // return at most 2 parts
// note: be sure to check it's not an empty array
string firstElem = array[0];
// note: be sure to check length first
string restOfArray = array[1];

This is very similar to the Substring method, just by a different means.

SQL Server doesn't have regular expressions. It uses the LIKE pattern matching syntax which isn't the same.

As it happens, you are close. Just need leading+trailing wildcards and move the NOT

 WHERE whatever NOT LIKE '%[a-z0-9]%'

Bandwidth is tiered by instance size, here's a comprehensive answer:

For t2/m3/c3/c4/r3/i2/d2 instances:

• t2.nano = ??? (Based on the scaling factors, I'd expect 20-30 MBit/s)
• t2.micro = ~70 MBit/s (qiita says 63 MBit/s) - t1.micro gets about ~100 Mbit/s
• t2.small = ~125 MBit/s (t2, qiita says 127 MBit/s, cloudharmony says 125 Mbit/s with spikes to 200+ Mbit/s)
• *.medium = t2.medium gets 250-300 MBit/s, m3.medium ~400 MBit/s
• *.large = ~450-600 MBit/s (the most variation, see below)
• *.xlarge = 700-900 MBit/s
• *.2xlarge = ~1 GBit/s +- 10%
• *.4xlarge = ~2 GBit/s +- 10%
• *.8xlarge and marked specialty = 10 Gbit, expect ~8.5 GBit/s, requires enhanced networking & VPC for full throughput

m1 small, medium, and large instances tend to perform higher than expected. c1.medium is another freak, at 800 MBit/s.

I gathered this by combing dozens of sources doing benchmarks (primarily using iPerf & TCP connections). Credit to CloudHarmony & flux7 in particular for many of the benchmarks (note that those two links go to google searches showing the numerous individual benchmarks).

Caveats & Notes:

The large instance size has the most variation reported:

• m1.large is ~800 Mbit/s (!!!)
• t2.large = ~500 MBit/s
• c3.large = ~500-570 Mbit/s (different results from different sources)
• c4.large = ~520 MBit/s (I've confirmed this independently, by the way)
• m3.large is better at ~700 MBit/s
• m4.large is ~445 Mbit/s
• r3.large is ~390 Mbit/s

Burstable (T2) instances appear to exhibit burstable networking performance too:

• The CloudHarmony iperf benchmarks show initial transfers start at 1 GBit/s and then gradually drop to the sustained levels above after a few minutes. PDF links to reports below:

• t2.small (PDF)

• t2.medium (PDF)
• t2.large (PDF)

Note that these are within the same region - if you're transferring across regions, real performance may be much slower. Even for the larger instances, I'm seeing numbers of a few hundred MBit/s.

You could use viewport-percentage lenghts.

See: http://stanhub.com/how-to-make-div-element-100-height-of-browser-window-using-css-only/

It works like this:

.element{
    height: 100vh; /* For 100% screen height */
    width:  100vw; /* For 100% screen width */
}

As the other answers didn't address my concern I decided to write my own answer.

The path given in the icon attribute of the md-icon directive is the URL of a .png or .svg file lying somewhere in your static file directory. So you have to put the right path of that file in the icon attribute. p.s put the file in the right directory so that your server could serve it.

Remember md-icon is not like bootstrap icons. Currently they are merely a directive that shows a .svg file.

Update

Angular material design has changed a lot since this question was posted.

Now there are several ways to use md-icon

The first way is to use SVG icons.

<md-icon md-svg-src = '<url_of_an_image_file>'></md-icon>

Example:

<md-icon md-svg-src = '/static/img/android.svg'></md-icon>

or

<md-icon md-svg-src = '{{ getMyIcon() }}'></md-icon>

:where getMyIcon is a method defined in $scope.

or <md-icon md-svg-icon="social:android"></md-icon>

to use this you have to the $mdIconProvider service to configure your application with svg iconsets.

angular.module('appSvgIconSets', ['ngMaterial'])  
  .controller('DemoCtrl', function($scope) {})  
  .config(function($mdIconProvider) {
    $mdIconProvider
      .iconSet('social', 'img/icons/sets/social-icons.svg', 24)
      .defaultIconSet('img/icons/sets/core-icons.svg', 24);    
  });

The second way is to use font icons.

<md-icon md-font-icon="android" alt="android"></md-icon>

<md-icon md-font-icon="fa-magic" class="fa" alt="magic wand"></md-icon>

prior to doing this you have to load the font library like this..

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

or use font icons with ligatures

<md-icon md-font-library="material-icons">face</md-icon>

<md-icon md-font-library="material-icons">#xE87C;</md-icon>

<md-icon md-font-library="material-icons" class="md-light md-48">face</md-icon>

For further details check our

Angular Material mdIcon Directive documentation

        std::cout << inner_iter->second << std::endl;
    }
}

or nicer in C++0x:

for(auto outer_iter=map.begin(); outer_iter!=map.end(); ++outer_iter) {
    for(auto inner_iter=outer_iter->second.begin(); inner_iter!=outer_iter->second.end(); ++inner_iter) {
        std::cout << inner_iter->second << std::endl;
    }
}

}

As far as I know, shouldOverrideUrlLoading is not called for images but rather for hyperlinks... I think the appropriate method is

@Override public void onLoadResource(WebView view, String url)

This method is called for every resource (image, styleesheet, script) that's loaded by the webview, but since it's a void, I haven't found a way to change that url and replace it so that it loads a local resource ...

I am not sure it will help but you can try this.This worked for me

Start -> Visual Studio Installer -> Repair

after this enable the Microsoft Symbols Server under

TOOLS->Options->Debugging->Symbols

This will automatically set all the issues.

This is not exactly a one-liner, but it turns all string keys into symbols, also the nested ones:

def recursive_symbolize_keys(my_hash)
  case my_hash
  when Hash
    Hash[
      my_hash.map do |key, value|
        [ key.respond_to?(:to_sym) ? key.to_sym : key, recursive_symbolize_keys(value) ]
      end
    ]
  when Enumerable
    my_hash.map { |value| recursive_symbolize_keys(value) }
  else
    my_hash
  end
end

Formerly I use the following code which is work correctly to redirect root URL of each of my domains/subdomains to their correspondence subdirectories which are named exactly as the sub/domain it self as below:

RewriteCond %{HTTP_HOST} ^sub1.domain1.com
RewriteCond %{REQUEST_URI} !subs/sub1.domain1.com/
RewriteRule ^(.*)$ subs/%{HTTP_HOST}/$1 [L,QSA]

RewriteCond %{HTTP_HOST} ^sub2.domain1.com
RewriteCond %{REQUEST_URI} !subs/sub1.domain2.com/
RewriteRule ^(.*)$ subs/%{HTTP_HOST}/$1 [L,QSA]

RewriteCond %{HTTP_HOST} ^sub1.domain2.com
RewriteCond %{REQUEST_URI} !subs/sub1.domain2.com/
RewriteRule ^(.*)$ subs/%{HTTP_HOST}/$1 [L,QSA]

RewriteCond %{HTTP_HOST} ^sub2.domain2.com
RewriteCond %{REQUEST_URI} !subs/sub2.domain2.com/
RewriteRule ^(.*)$ subs/%{HTTP_HOST}/$1 [L,QSA]

However when I want to add another subs or domains then it will need to be added in the above code. It should be much more convenient to simplify it to work like wildcard (*) as below:

RewriteCond %{HTTP_HOST} ^sub
RewriteCond %{REQUEST_URI} !/subs/
RewriteRule ^(.*)$ subs/%{HTTP_HOST}/$1 [L,QSA]

So whenever another subdomains/domains is added as long as the subdomain name has a prefix of sub (like: sub3.domain1.com, sub1.domain3.com etc.) the code will remain valid.

Some of the core differences between C# and Javascript script syntax in Unity.

http://unity3d.com/learn/tutorials/modules/beginner/scripting/c-sharp-vs-javascript-syntax

but keep in mind C# is the best one to develop in unity

What about this. Let's define a simple helping If component.

var If = React.createClass({
    render: function() {
        if (this.props.test) {
            return this.props.children;
        }
        else {
            return false;
        }
    }
});

And use it this way:

render: function () {
    return (
        <div id="page">
            <If test={this.state.banner}>
                <div id="banner">{this.state.banner}</div>
            </If>
            <div id="other-content">
                blah blah blah...
            </div>
        </div>
    );
}

UPDATE: As my answer is getting popular, I feel obligated to warn you about the biggest danger related to this solution. As pointed out in another answer, the code inside the <If /> component is executed always regardless of whether the condition is true or false. Therefore the following example will fail in case the banner is null (note the property access on the second line):

<If test={this.state.banner}>
    <div id="banner">{this.state.banner.url}</div>
</If>

You have to be careful when you use it. I suggest reading other answers for alternative (safer) approaches.

UPDATE 2: Looking back, this approach is not only dangerous but also desperately cumbersome. It's a typical example of when a developer (me) tries to transfer patterns and approaches he knows from one area to another but it doesn't really work (in this case other template languages).

If you need a conditional element, do it like this:

render: function () {
    return (
        <div id="page">
            {this.state.banner &&
                <div id="banner">{this.state.banner}</div>}
            <div id="other-content">
                blah blah blah...
            </div>
        </div>
    );
}

If you also need the else branch, just use a ternary operator:

{this.state.banner ?
   <div id="banner">{this.state.banner}</div> :
   <div>There is no banner!</div>
}

It's way shorter, more elegant and safe. I use it all the time. The only disadvantage is that you cannot do else if branching that easily but that is usually not that common.

Anyway, this is possible thanks to how logical operators in JavaScript work. The logical operators even allow little tricks like this:

<h3>{this.state.banner.title || 'Default banner title'}</h3>

What about constructing the element using jQuery? e.g.

$("<div></div>")

creates a new div element, ready to be added to the page. Can be shortened further to

$("<div>")

then you can chain on commands that you need, set up event handlers and append it to the DOM. For example

$('<div id="myid">Div Content</div>')
    .bind('click', function(e) { /* event handler here */ })
    .appendTo('#myOtherDiv');

SparkSQl support writing programs using Dataset and Dataframe API, along with it need to support sql.

In order to support Sql on DataFrames, first it requires a table definition with column names are required, along with if it creates tables the hive metastore will get lot unnecessary tables, because Spark-Sql natively resides on hive. So it will create a temporary view, which temporarily available in hive for time being and used as any other hive table, once the Spark Context stop it will be removed.

In order to create the view, developer need an utility called createOrReplaceTempView

You can get the user's WindowsIdentity object under Windows Authentication by:

WindowsIdentity identity = HttpContext.Current.Request.LogonUserIdentity;

and then you can get the information about the user like identity.Name.

Please note you need to have HttpContext for these code.

• Odd jQuery problem - Ajax request to a C program not quite working

The problem was the XHR Cross Domain Policy, and a useful tip on how to get around it by using a technique called JSONP. The big downside is that JSONP does not support POST requests.

For Debian Jessie and Stretch installing the following packages resolves the issue:

sudo apt install libblas3 liblapack3 liblapack-dev libblas-dev

If you want an optimized scipy, you can also install the optional libatlas-base-dev package:

If you have a valid dtd file for the xml then you can easily transform json to xml and xml to json using the eclipselink jar binary.

The article also has a sample project (including the supporting third party jars) as a zip file which can be downloaded for reference purpose.

static is a heavily overloaded word in C and C++. static variables in the context of a function are variables that hold their values between calls. They exist for the duration of the program.

local variables persist only for the lifetime of a function or whatever their enclosing scope is. For example:

void foo()
{
    int i, j, k;
    //initialize, do stuff
} //i, j, k fall out of scope, no longer exist

Sometimes this scoping is used on purpose with { } blocks:

{ 
   int i, j, k;
   //...
} //i, j, k now out of scope

global variables exist for the duration of the program.

auto is now different in C and C++. auto in C was a (superfluous) way of specifying a local variable. In C++11, auto is now used to automatically derive the type of a value/expression.

Lots of people have suggested POSIX sleep, Windows Sleep, Windows system("pause"), C++ cin.get()… there's even a DOS getch() in there, from roughly the late 1920s.

Please don't do any of these.

None of these solutions would pass code review in my team. That means, if you submitted this code for inclusion in our products, your commit would be blocked and you would be told to go and find another solution. (One might argue that things aren't so serious when you're just a hobbyist playing around, but I propose that developing good habits in your pet projects is what will make you a valued professional in a business organisation, and keep you hired.)

Keeping the console window open so you can read the output of your program is not the responsibility of your program! When you add a wait/sleep/block to the end of your program, you are violating the single responsibility principle, creating a massive abstraction leak, and obliterating the re-usability/chainability of your program. It no longer takes input and gives output — it blocks for transient usage reasons. This is very non-good.

Instead, you should configure your environment to keep the prompt open after your program has finished its work. Your Batch script wrapper is a good approach! I can see how it would be annoying to have to keep manually updating, and you can't invoke it from your IDE. You could make the script take the path to the program to execute as a parameter, and configure your IDE to invoke it instead of your program directly.

An interim, quick-start approach would be to change your IDE's run command from cmd.exe <myprogram> or <myprogram>, to cmd.exe /K <myprogram>. The /K switch to cmd.exe makes the prompt stay open after the program at the given path has terminated. This is going to be slightly more annoying than your Batch script solution, because now you have to type exit or click on the red 'X' when you're done reading your program's output, rather than just smacking the space bar.

^{I assume usage of an IDE, because otherwise you're already invoking from a command prompt, and this would not be a problem in the first place. Furthermore, I assume the use of Windows (based on detail given in the question), but this answer applies to any platform… which is, incidentally, half the point.}

None of the above worked for me. And it took me long to figure it out, hopefully this helps the next guy.

I'm using Ubuntu 12.04 LTS with mailutils v2.1.

I found this solutions somewhere on the net, don't know where, can't find it again:

-aFrom:[email protected]

Full Command used:

cat /root/Reports/ServerName-Report-$DATE.txt | mail -s "Server-Name-Report-$DATE" [email protected] -aFrom:[email protected]

you can use the java reflect api:

    @PrePersist
    void preInsert() {
       PrePersistUtil.pre(this);
    }

This is common:

    public class PrePersistUtil {

        private static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");


        public static void pre(Object object){
            try {
                Field[] fields = object.getClass().getDeclaredFields();
                for(Field field : fields){
                    field.setAccessible(true);
                    if (field.getType().getName().equals("java.lang.Long")
                            && field.get(object) == null){
                        field.set(object,0L);
                    }else if    (field.getType().getName().equals("java.lang.String")
                            && field.get(object) == null){
                        field.set(object,"");
                    }else if (field.getType().getName().equals("java.util.Date")
                            && field.get(object) == null){
                        field.set(object,sdf.parse("1900-01-01"));
                    }else if (field.getType().getName().equals("java.lang.Double")
                            && field.get(object) == null){
                        field.set(object,0.0d);
                    }else if (field.getType().getName().equals("java.lang.Integer")
                            && field.get(object) == null){
                        field.set(object,0);
                    }else if (field.getType().getName().equals("java.lang.Float")
                            && field.get(object) == null){
                        field.set(object,0.0f);
                    }
                }
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            } catch (ParseException e) {
                e.printStackTrace();
            }
        }
    }

With ES2018, you are able to greatly simplify all of the above answers to:

async function printFiles () {
  const files = await getFilePaths()

  for await (const contents of files.map(file => fs.readFile(file, 'utf8'))) {
    console.log(contents)
  }
}

See spec: proposal-async-iteration

2018-09-10: This answer has been getting a lot attention recently, please see Axel Rauschmayer's blog post for further information about asynchronous iteration: ES2018: asynchronous iteration

As stated by Jürgen Math using the preg_replace method listed by user2254008 fixed it for me as well.

This is not limited to Chrome, it appears to be a character set conversion issue (at least in my case, Unicode -> UTF8) This fixed all the issues i was having.

As a future node, the JSON Object i was decoding came from Python's json.dumps function. This in turn caused some other unsanitary data to make it across though it was easily dealt with.

If someone is still interested, I found this article on DATABASE.GUIDE:
Left Padding in SQL Server – 3 LPAD() Equivalents

In short, there are 3 methods mentioned in that article.
Let's say your id=12 and you need it to display as 0012.

Method 1 – Use the RIGHT() Function
The first method uses the RIGHT() function to return only the rightmost part of the string, after adding some leading zeros.

SELECT RIGHT('00' + '12', 4);

Result:
0012

Method 2 – Use a Combination of RIGHT() and REPLICATE()
This method is almost the same as the previous method, with the only difference being that I simply replace the three zeros with the REPLICATE() function:

SELECT RIGHT(REPLICATE('0', 2) + '12', 4);

Result:
0012

Method 3 – Use a Combination of REPLACE() and STR()
This method comes from a completely different angle to the previous methods:

SELECT REPLACE(STR('12', 4),' ','0');

Result:
0012

Check out the article, there is more in depth analysis with examples.

The other answers all point out that you should not catch generic exceptions, but no one seems to want to tell you why, which is essential to understanding when you can break the "rule". Here is an explanation. Basically, it's so that you don't hide:

• the fact that an error occurred
• the specifics of the error that occurred (error hiding antipattern)

So as long as you take care to do none of those things, it's OK to catch the generic exception. For instance, you could provide information about the exception to the user another way, like:

• Present exceptions as dialogs in a GUI
• Transfer exceptions from a worker thread or process to the controlling thread or process in a multithreading or multiprocessing application

So how to catch the generic exception? There are several ways. If you just want the exception object, do it like this:

try:
    someFunction()
except Exception as ex:
    template = "An exception of type {0} occurred. Arguments:\n{1!r}"
    message = template.format(type(ex).__name__, ex.args)
    print message

Make sure message is brought to the attention of the user in a hard-to-miss way! Printing it, as shown above, may not be enough if the message is buried in lots of other messages. Failing to get the users attention is tantamount to swallowing all exceptions, and if there's one impression you should have come away with after reading the answers on this page, it's that this is not a good thing. Ending the except block with a raise statement will remedy the problem by transparently reraising the exception that was caught.

The difference between the above and using just except: without any argument is twofold:

• A bare except: doesn't give you the exception object to inspect
• The exceptions SystemExit, KeyboardInterrupt and GeneratorExit aren't caught by the above code, which is generally what you want. See the exception hierarchy.

If you also want the same stacktrace you get if you do not catch the exception, you can get that like this (still inside the except clause):

import traceback
print traceback.format_exc()

If you use the logging module, you can print the exception to the log (along with a message) like this:

import logging
log = logging.getLogger()
log.exception("Message for you, sir!")

If you want to dig deeper and examine the stack, look at variables etc., use the post_mortem function of the pdb module inside the except block:

import pdb
pdb.post_mortem()

I've found this last method to be invaluable when hunting down bugs.

I know this is pretty old question but it topped the list when I searched. So I wanted to update with another method.

In the strings.xml file you can do the \n or you can simply press enter:

<string name="Your string name" > This is your string.

   This is the second line of your string.\n\n Third line of your string.</string>

This will result in the following on your TextView:

This is your string.

This is the second line of your string.

Third line of your string.

This is because there were two returns between the beginning declaration of the string and the new line. I also added the \n to it for clarity, as either can be used. I like to use the carriage returns in the xml to be able to see a list or whatever multiline string I have. My two cents.

In past projects I worked on, the endpoint was a relative property. That is to say it may or may not have been appended to, but it always contained the protocol://host:port/partOfThePath.

If the service being called had a dynamic part to it, for example a ?param=dynamicValue, then that part would get added to the endpoint. But many times the endpoint could be used as is without having to be amended.

Whats important to understand is what an endpoint is not and how it helps. For example an alternative way to pass the information stored in an endpoint would be to store the different parts of the endpoint in separate properties. For example:

hostForServiceA=someIp
portForServiceA=8080
pathForServiceA=/some/service/path
hostForServiceB=someIp
portForServiceB=8080
pathForServiceB=/some/service/path

Or if the same host and port across multiple services:

host=someIp
port=8080
pathForServiceA=/some/service/path
pathForServiceB=/some/service/path

In those cases the full URL would need to be constructed in your code as such:

String url = "http://" + host + ":" + port + pathForServiceA  + "?" + dynamicParam + "=" + dynamicValue;

In contract this can be stored as an endpoint as such

serviceAEndpoint=http://host:port/some/service/path?dynamicParam=

And yes many times we stored the endpoint up to and including the '='. This lead to code like this:

String url = serviceAEndpoint + dynamicValue;

Hope that sheds some light.

tl;dr

LocalDate                       // Represents an entire day, without time-of-day and without time zone.
.now(                           // Capture the current date.
    ZoneId.of( "Asia/Tokyo" )   // Returns a `ZoneId` object.
)                               // Returns a `LocalDate` object.
.atStartOfDay(                  // Determines the first moment of the day as seen on that date in that time zone. Not all days start at 00:00!
    ZoneId.of( "Asia/Tokyo" ) 
)                               // Returns a `ZonedDateTime` object.

Start of day

Get the full length of the today as seen in a time zone.

Using Half-Open approach, where the beginning is inclusive while the ending is exclusive. This approach solves the flaw in your code that fails to account for the very last second of the day.

ZoneId zoneId = ZoneId.of( "Africa/Tunis" ) ;
LocalDate today = LocalDate.now( zoneId  ) ;

ZonedDateTime zdtStart = today.atStartOfDay( zoneId ) ;
ZonedDateTime zdtStop = today.plusDays( 1 ).atStartOfDay( zoneId ) ;

zdtStart.toString() = 2020-01-30T00:00+01:00[Africa/Tunis]

zdtStop.toString() = 2020-01-31T00:00+01:00[Africa/Tunis]

See the same moments in UTC.

Instant start = zdtStart.toInstant() ;
Instant stop = zdtStop.toInstant() ;

start.toString() = 2020-01-29T23:00:00Z

stop.toString() = 2020-01-30T23:00:00Z

If you want the entire day of a date as seen in UTC rather than in a time zone, use OffsetDateTime.

LocalDate today = LocalDate.now( ZoneOffset.UTC  ) ;

OffsetDateTime odtStart = today.atTime( OffsetTime.MIN ) ;
OffsetDateTime odtStop = today.plusDays( 1 ).atTime( OffsetTime.MIN ) ;

odtStart.toString() = 2020-01-30T00:00+18:00

odtStop.toString() = 2020-01-31T00:00+18:00

These OffsetDateTime objects will already be in UTC, but you can call toInstant if you need such objects which are always in UTC by definition.

Instant start = odtStart.toInstant() ;
Instant stop = odtStop.toInstant() ;

start.toString() = 2020-01-29T06:00:00Z

stop.toString() = 2020-01-30T06:00:00Z

Tip: You may be interested in adding the ThreeTen-Extra library to your project to use its Interval class to represent this pair of Instant objects. This class offers useful methods for comparison such as abuts, overlaps, contains, and more.

Interval interval = Interval.of( start , stop ) ;

interval.toString() = 2020-01-29T06:00:00Z/2020-01-30T06:00:00Z

Half-Open

The answer by mprivat is correct. His point is to not try to obtain end of a day, but rather compare to "before start of next day". His idea is known as the "Half-Open" approach where a span of time has a beginning that is inclusive while the ending is exclusive.

• The current date-time frameworks of Java (java.util.Date/Calendar and Joda-Time) both use milliseconds from the epoch. But in Java 8, the new JSR 310 java.time.* classes use nanoseconds resolution. Any code you wrote based on forcing the milliseconds count of last moment of day would be incorrect if switched to the new classes.
• Comparing data from other sources becomes faulty if they employ other resolutions. For example, Unix libraries typically employ whole seconds, and databases such as Postgres resolve date-time to microseconds.
• Some Daylight Saving Time changes happen over midnight which might further confuse things.

Joda-Time 2.3 offers a method for this very purpose, to obtain first moment of the day: withTimeAtStartOfDay(). Similarly in java.time, LocalDate::atStartOfDay.

Search StackOverflow for "joda half-open" to see more discussion and examples.

See this post, Time intervals and other ranges should be half-open, by Bill Schneider.

Avoid legacy date-time classes

The java.util.Date and .Calendar classes are notoriously troublesome. Avoid them.

Use java.time classes. The java.time framework is the official successor of the highly successful Joda-Time library.

java.time

The java.time framework is built into Java 8 and later. Back-ported to Java 6 & 7 in the ThreeTen-Backport project, further adapted to Android in the ThreeTenABP project.

An Instant is a moment on the timeline in UTC with a resolution of nanoseconds.

Instant instant = Instant.now();

Apply a time zone to get the wall-clock time for some locality.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

To get the first moment of the day go through the LocalDate class and its atStartOfDay method.

ZonedDateTime zdtStart = zdt.toLocalDate().atStartOfDay( zoneId );

Using Half-Open approach, get first moment of following day.

ZonedDateTime zdtTomorrowStart = zdtStart.plusDays( 1 );

Currently the java.time framework lacks an Interval class as described below for Joda-Time. However, the ThreeTen-Extra project extends java.time with additional classes. This project is the proving ground for possible future additions to java.time. Among its classes is Interval. Construct an Interval by passing a pair of Instant objects. We can extract an Instant from our ZonedDateTime objects.

Interval today = Interval.of( zdtStart.toInstant() , zdtTomorrowStart.toInstant() );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 brought some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android (26+) bundle implementations of the java.time classes.
  • For earlier Android (<26), a process known as API desugaring brings a subset of the java.time functionality not originally built into Android.
    • If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. See How to use ThreeTenABP….

Joda-Time

UPDATE: The Joda-Time project is now in maintenance-mode, and advises migration to the java.time classes. I am leaving this section intact for history.

Joda-Time has three classes to represent a span of time in various ways: Interval, Period, and Duration. An Interval has a specific beginning and ending on the timeline of the Universe. This fits our need to represent "a day".

We call the method withTimeAtStartOfDay rather than set time of day to zeros. Because of Daylight Saving Time and other anomalies the first moment of the day may not be 00:00:00.

Example code using Joda-Time 2.3.

DateTimeZone timeZone = DateTimeZone.forID( "America/Montreal" );
DateTime now = DateTime.now( timeZone );
DateTime todayStart = now.withTimeAtStartOfDay();
DateTime tomorrowStart = now.plusDays( 1 ).withTimeAtStartOfDay();
Interval today = new Interval( todayStart, tomorrowStart );

If you must, you can convert to a java.util.Date.

java.util.Date date = todayStart.toDate();

You can save some homemade factorial functions on a separate module, utils.py, and then import them and compare the performance with the predefinite one, in scipy, numpy and math using timeit. In this case I used as external method the last proposed by Stefan Gruenwald:

import numpy as np


def factorial(n):
    return reduce((lambda x,y: x*y),range(1,n+1))

Main code (I used a framework proposed by JoshAdel in another post, look for how-can-i-get-an-array-of-alternating-values-in-python):

from timeit import Timer
from utils import factorial
import scipy

    n = 100

    # test the time for the factorial function obtained in different ways:

    if __name__ == '__main__':

        setupstr="""
    import scipy, numpy, math
    from utils import factorial
    n = 100
    """

        method1="""
    factorial(n)
    """

        method2="""
    scipy.math.factorial(n)  # same algo as numpy.math.factorial, math.factorial
    """

        nl = 1000
        t1 = Timer(method1, setupstr).timeit(nl)
        t2 = Timer(method2, setupstr).timeit(nl)

        print 'method1', t1
        print 'method2', t2

        print factorial(n)
        print scipy.math.factorial(n)

Which provides:

method1 0.0195569992065
method2 0.00638914108276

93326215443944152681699238856266700490715968264381621468592963895217599993229915608941463976156518286253697920827223758251185210916864000000000000000000000000

Inside your manifest:

android:windowSoftInputMode="stateAlwaysVisible" - initially launched keyboard. android:windowSoftInputMode="stateAlwaysHidden" - initially hidden keyboard.

I like to use also "adjustPan" because when the keyboard launches then the screen auto adjusts.

 <activity
      android:name="YourActivity"
      android:windowSoftInputMode="stateAlwaysHidden|adjustPan"/>

A PDB file contains information used by the debugger. It is not required to run your application and it does not need to be included in your released version.

You can disable pdb files from being created in Visual Studio. If you are building from the command line or a script then omit the /Debug switch.

With a = subprocess.Popen("cdrecord --help",stdout = subprocess.PIPE) , you need to either use a list or use shell=True;

Either of these will work. The former is preferable.

a = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE)

a = subprocess.Popen('cdrecord --help', shell=True, stdout=subprocess.PIPE)

Also, instead of using Popen.stdout.read/Popen.stderr.read, you should use .communicate() (refer to the subprocess documentation for why).

proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = proc.communicate()

I recommended using the size function.

class Customer < ActiveRecord::Base
  has_many :customer_activities
end

class CustomerActivity < ActiveRecord::Base
  belongs_to :customer, counter_cache: true
end

Consider these two models. The customer has many customer activities.

If you use a :counter_cache on a has_many association, size will use the cached count directly, and not make an extra query at all.

Consider one example: in my database, one customer has 20,000 customer activities and I try to count the number of records of customer activities of that customer with each of count, length and size method. here below the benchmark report of all these methods.

            user     system      total        real
Count:     0.000000   0.000000   0.000000 (  0.006105)
Size:      0.010000   0.000000   0.010000 (  0.003797)
Length:    0.030000   0.000000   0.030000 (  0.026481)

so I found that using :counter_cache Size is the best option to calculate the number of records.

For version v2.2.2 and newer

In version v2.2.2 and up, name property no longer exists and it shouldn't be used to define the route. path should be used instead of name and no leading slash is needed on the path. In this case use path: '404' instead of path: '/404':

 {path: '404', component: NotFoundComponent},
 {path: '**', redirectTo: '/404'}

For versions older than v2.2.2

you can use {path: '/*path', redirectTo: ['redirectPathName']}:

{path: '/home/...', name: 'Home', component: HomeComponent}
{path: '/', redirectTo: ['Home']},
{path: '/user/...', name: 'User', component: UserComponent},
{path: '/404', name: 'NotFound', component: NotFoundComponent},

{path: '/*path', redirectTo: ['NotFound']}

if no path matches then redirect to NotFound path

LEFT OUTER JOIN

SELECT * FROM A, B WHERE A.column = B.column(+)

RIGHT OUTER JOIN

SELECT * FROM A, B WHERE A.column (+)= B.column

Maybe this is a bit redundant, but no one appeared to have mentioned this as a solution.

As a beginner in SQL I find that when using a BEGIN and END SSMS usually adds a squiggly line with incorrect syntax near 'END' to END, simply because there's no content in between yet. If you're just setting up BEGIN and END to get started and add the actual query later, then simply add a bogus PRINT statement so SSMS stops bothering you.

For example:

IF (1=1)
BEGIN
  PRINT 'BOGUS'
END

The following will indeed set you on the wrong track, thinking you made a syntax error which in this case just means you still need to add content in between BEGIN and END:

IF (1=1)
BEGIN
END

You only need a single line of code to set the border around every cell in the range:

Range("A1:F20").Borders.LineStyle = xlContinuous

It's also easy to apply multiple effects to the border around each cell.

For example:

Sub RedOutlineCells()
    Dim rng As Range

    Set rng = Range("A1:F20")

    With rng.Borders
        .LineStyle = xlContinuous
        .Color = vbRed
        .Weight = xlThin
    End With
End Sub

This should work if the date format is consistent:

select SUBSTRING_INDEX( subdateshow,"/",-1 ) from table 

SELECT COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA='bodb' AND TABLE_NAME='abc';

works for getting all column names

You can view this dump from the UNIX console.

The path for the heap dump will be provided as a variable right after where you have placed the mentioned variable.

E.g.:

-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=${DOMAIN_HOME}/logs/mps"

You can view the dump from the console on the mentioned path.

the one liner for python3 is :

def bytes_xor(a, b) :
    return bytes(x ^ y for x, y in zip(a, b))

where a, b and the returned value are bytes() instead of str() of course

can't be easier, I love python3 :)

I think the reason the OPs code does not work is because once you call Remove you are changing the Length of drr. When you call Delete you are not actually deleting the row until AcceptChanges is called. This is why if you want to use Remove you need a separate loop.

Depending on the situation or preference...

string colName = "colName";
string comparisonValue = (whatever it is).ToString();
string strFilter = (dtbl.Columns[colName].DataType == typeof(string)) ? "[" + colName + "]='" + comparisonValue + "'" : "[" + colName + "]=" + comparisonValue;
string strSort = "";

DataRow[] drows = dtbl.Select(strFilter, strSort, DataViewRowState.CurrentRows);

Above used for next two examples

foreach(DataRow drow in drows)
{
   drow.Delete();//Mark a row for deletion.
}
dtbl.AcceptChanges();

OR

foreach(DataRow drow in drows)
{
   dtbl.Rows[dtbl.Rows.IndexOf(drow)].Delete();//Mark a row for deletion.
}
dtbl.AcceptChanges();

OR

List<DataRow> listRowsToDelete = new List<DataRow>();

foreach(DataRow drow in dtbl.Rows)
{
   if(condition to delete)
   {
      listRowsToDelete.Add(drow);
   }
}

foreach(DataRow drowToDelete in listRowsToDelete)
{
   dtbl.Rows.Remove(drowToDelete);// Calling Remove is the same as calling Delete and then calling AcceptChanges
}

Note that if you call Delete() then you should call AcceptChanges() but if you call Remove() then AcceptChanges() is not necessary.

Also, here is a good link on row filter syntax.

You can do something like this to check if any mysql process is running or not:

ps aux | grep mysqld
ps aux | grep mysql

Then if it is running you can killall by using(depending on what all processes are running currently):

killall -9 mysql
killall -9 mysqld
killall -9 mysqld_safe    

You can also use:

dat1 = pd.concat([dat1, dat2], axis=1)

All previous answers are correct here is a very simple example:

#! /usr/bin/env python
import json

def write_json():
    # create a dictionary  
    student_data = {"students":[]}
    #create a list
    data_holder = student_data["students"]
    # just a counter
    counter = 0
    #loop through if you have multiple items..         
    while counter < 3:
        data_holder.append({'id':counter})
        data_holder.append({'room':counter})
        counter += 1    
    #write the file        
    file_path='/tmp/student_data.json'
    with open(file_path, 'w') as outfile:
        print("writing file to: ",file_path)
        # HERE IS WHERE THE MAGIC HAPPENS 
        json.dump(student_data, outfile)
    outfile.close()     
    print("done")

write_json()

// Two-dimensional GetLength example.
int[,] two = new int[5, 10];
Console.WriteLine(two.GetLength(0)); // Writes 5
Console.WriteLine(two.GetLength(1)); // Writes 10

I had to apply 100% to both html and body.

this.TextBox3.Text = DateTime.Now.ToString("MM.dd.yyyy");

setup.py is Python's answer to a multi-platform installer and make file.

If you’re familiar with command line installations, then make && make install translates to python setup.py build && python setup.py install.

Some packages are pure Python, and are only byte compiled. Others may contain native code, which will require a native compiler (like gcc or cl) and a Python interfacing module (like swig or pyrex).

You can add a new property of type IFormFile to your view model

public class CreatePost
{
   public string ImageCaption { set;get; }
   public string ImageDescription { set;get; }
   public IFormFile MyImage { set; get; }
}

and in your GET action method, we will create an object of this view model and send to the view.

public IActionResult Create()
{
   return View(new CreatePost());
}

Now in your Create view which is strongly typed to our view model, have a form tag which has the enctype attribute set to "multipart/form-data"

@model CreatePost
<form asp-action="Create" enctype="multipart/form-data">   

    <input asp-for="ImageCaption"/>
    <input asp-for="ImageDescription"/>
    <input asp-for="MyImage"/>

    <input type="submit"/>
</form>

And your HttpPost action to handle the form posting

[HttpPost]
public IActionResult Create(CreatePost model)
{
   var img = model.MyImage;
   var imgCaption = model.ImageCaption;

   //Getting file meta data
   var fileName = Path.GetFileName(model.MyImage.FileName);
   var contentType = model.MyImage.ContentType;

   // do something with the above data
   // to do : return something
}

If you want to upload the file to some directory in your app, you should use IHostingEnvironment to get the webroot path. Here is a working sample.

public class HomeController : Controller
{
    private readonly IHostingEnvironment hostingEnvironment;
    public HomeController(IHostingEnvironment environment)
    {
        hostingEnvironment = environment;
    }
    [HttpPost]
    public IActionResult Create(CreatePost model)
    {
        // do other validations on your model as needed
        if (model.MyImage != null)
        {
            var uniqueFileName = GetUniqueFileName(model.MyImage.FileName);
            var uploads = Path.Combine(hostingEnvironment.WebRootPath, "uploads");
            var filePath = Path.Combine(uploads,uniqueFileName);
            model.MyImage.CopyTo(new FileStream(filePath, FileMode.Create)); 

            //to do : Save uniqueFileName  to your db table   
        }
        // to do  : Return something
        return RedirectToAction("Index","Home");
    }
    private string GetUniqueFileName(string fileName)
    {
        fileName = Path.GetFileName(fileName);
        return  Path.GetFileNameWithoutExtension(fileName)
                  + "_" 
                  + Guid.NewGuid().ToString().Substring(0, 4) 
                  + Path.GetExtension(fileName);
    }
}

This will save the file to uploads folder inside wwwwroot directory of your app with a random file name generated using Guids ( to prevent overwriting of files with same name)

Here we are using a very simple GetUniqueName method which will add 4 chars from a guid to the end of the file name to make it somewhat unique. You can update the method to make it more sophisticated as needed.

Should you be storing the full url to the uploaded image in the database ?

No. Do not store the full url to the image in the database. What if tomorrow your business decides to change your company/product name from www.thefacebook.com to www.facebook.com ? Now you have to fix all the urls in the table!

What should you store ?

You should store the unique filename which you generated above(the uniqueFileName varibale we used above) to store the file name. When you want to display the image back, you can use this value (the filename) and build the url to the image.

For example, you can do this in your view.

@{
    var imgFileName = "cats_46df.png";
}
<img src="~/uploads/@imgFileName"  alt="my img"/>

I just hardcoded an image name to imgFileName variable and used that. But you may read the stored file name from your database and set to your view model property and use that. Something like

<img src="~/uploads/@Model.FileName"  alt="my img"/>

Storing the image to table

If you want to save the file as bytearray/varbinary to your database, you may convert the IFormFile object to byte array like this

private byte[] GetByteArrayFromImage(IFormFile file)
{
    using (var target = new MemoryStream())
    {
        file.CopyTo(target);
        return target.ToArray();
    }
}

Now in your http post action method, you can call this method to generate the byte array from IFormFile and use that to save to your table. the below example is trying to save a Post entity object using entity framework.

[HttpPost]
public IActionResult Create(CreatePost model)
{
    //Create an object of your entity class and map property values
    var post=new Post() { ImageCaption = model.ImageCaption };

    if (model.MyImage != null)
    {
       post.Image =  GetByteArrayFromImage(model.MyImage);
    }
    _context.Posts.Add(post);
    _context.SaveChanges();
    return RedirectToAction("Index","Home");
}

Do it in stages, and modify the object, like this:

# make a string with the request type in it:
method = "POST"
# create a handler. you can specify different handlers here (file uploads etc)
# but we go for the default
handler = urllib2.HTTPHandler()
# create an openerdirector instance
opener = urllib2.build_opener(handler)
# build a request
data = urllib.urlencode(dictionary_of_POST_fields_or_None)
request = urllib2.Request(url, data=data)
# add any other information you want
request.add_header("Content-Type",'application/json')
# overload the get method function with a small anonymous function...
request.get_method = lambda: method
# try it; don't forget to catch the result
try:
    connection = opener.open(request)
except urllib2.HTTPError,e:
    connection = e

# check. Substitute with appropriate HTTP code.
if connection.code == 200:
    data = connection.read()
else:
    # handle the error case. connection.read() will still contain data
    # if any was returned, but it probably won't be of any use

This way allows you to extend to making PUT, DELETE, HEAD and OPTIONS requests too, simply by substituting the value of method or even wrapping it up in a function. Depending on what you're trying to do, you may also need a different HTTP handler, e.g. for multi file upload.

Check the closures how they have been implemented in the lambdaj library. They actually have a behavior very similar to C# delegates:

http://code.google.com/p/lambdaj/wiki/Closures

If you want to extract from a tag then

$('.dep_buttons').text().substr(0,25)

With the mouseover event,

$(this).text($(this).text().substr(0, 25));

The above will extract the text of a tag, then extract again assign it back.

Short answer: Your foo() method returns immediately, while the $ajax() call executes asynchronously after the function returns. The problem is then how or where to store the results retrieved by the async call once it returns.

Several solutions have been given in this thread. Perhaps the easiest way is to pass an object to the foo() method, and to store the results in a member of that object after the async call completes.

function foo(result) {
    $.ajax({
        url: '...',
        success: function(response) {
            result.response = response;   // Store the async result
        }
    });
}

var result = { response: null };   // Object to hold the async result
foo(result);                       // Returns before the async completes

Note that the call to foo() will still return nothing useful. However, the result of the async call will now be stored in result.response.

Use LocalBroadcastManager to register a receiver to listen for a broadcast sent from local service inside your app, reference goes here:

My solution was to add a UIView with height of 20 points on top of the window when on iOS 7. Then I created a method in my AppDelegate class to show/hide the "solid" status bar background. In application:didFinishLaunchingWithOptions::

// ...

// Add a status bar background
self.statusBarBackground = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.window.bounds.size.width, 20.0f)];
self.statusBarBackground.backgroundColor = [UIColor blackColor];
self.statusBarBackground.alpha = 0.0;
self.statusBarBackground.userInteractionEnabled = NO;
self.statusBarBackground.layer.zPosition = 999; // Position its layer over all other views
[self.window addSubview:self.statusBarBackground];

// ...
return YES;

Then I created a method to fade in/out the black status bar background:

- (void) showSolidStatusBar:(BOOL) solidStatusBar
{
    [UIView animateWithDuration:0.3f animations:^{
        if(solidStatusBar)
        {
            [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
            self.statusBarBackground.alpha = 1.0f;
        }
        else
        {
            [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];
            self.statusBarBackground.alpha = 0.0f;
        }
    }];
}

All I have to do now is call is [appDelegate showSolidStatusBar:YES] when needed.

I encountered the same issue. This worked:

The client_id and client_secret, by default, should go in the Authorization header, not the form-urlencoded body.

1. Concatenate your client_id and client_secret, with a colon between them: [email protected]:12345678.
2. Base 64 encode the result: YWJjQGdtYWlsLmNvbToxMjM0NTY3OA==
3. Set the Authorization header: Authorization: Basic YWJjQGdtYWlsLmNvbToxMjM0NTY3OA==

What you have should work, unless ${STATUS} is empty. It would probably be better to do:

if ! [ "${STATUS}" -eq 200 ] 2> /dev/null && [ "${STRING}" != "${VALUE}" ]; then

or

if [ "${STATUS}" != 200 ] && [ "${STRING}" != "${VALUE}" ]; then

It's hard to say, since you haven't shown us exactly what is going wrong with your script.

Personal opinion: never use [[. It suppresses important error messages and is not portable to different shells.

ALL_CONSTRAINTS describes constraint definitions on tables accessible to the current user.

DBA_CONSTRAINTS describes all constraint definitions in the database.

USER_CONSTRAINTS describes constraint definitions on tables in the current user's schema

Indeed, just as commented by Tim Williams, the way to make it work is pre-formatting as text. Thus, to do it all via VBA, just do that:

Cells(1, 1).NumberFormat = "@"
Cells(1, 1).Value = "1234,56"

This is a symlink resolver in Bash that works whether the link is a directory or a non-directory:

function readlinks {(
  set -o errexit -o nounset
  declare n=0 limit=1024 link="$1"

  # If it's a directory, just skip all this.
  if cd "$link" 2>/dev/null
  then
    pwd -P
    return 0
  fi

  # Resolve until we are out of links (or recurse too deep).
  while [[ -L $link ]] && [[ $n -lt $limit ]]
  do
    cd "$(dirname -- "$link")"
    n=$((n + 1))
    link="$(readlink -- "${link##*/}")"
  done
  cd "$(dirname -- "$link")"

  if [[ $n -ge $limit ]]
  then
    echo "Recursion limit ($limit) exceeded." >&2
    return 2
  fi

  printf '%s/%s\n' "$(pwd -P)" "${link##*/}"
)}

Note that all the cd and set stuff takes place in a subshell.

Singleton Shared Preferences Class. it may help for others in future.

import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;

public class SharedPref
{
    private static SharedPreferences mSharedPref;
    public static final String NAME = "NAME";
    public static final String AGE = "AGE";
    public static final String IS_SELECT = "IS_SELECT";

    private SharedPref()
    {

    }

    public static void init(Context context)
    {
        if(mSharedPref == null)
            mSharedPref = context.getSharedPreferences(context.getPackageName(), Activity.MODE_PRIVATE);
    }

    public static String read(String key, String defValue) {
        return mSharedPref.getString(key, defValue);
    }

    public static void write(String key, String value) {
        SharedPreferences.Editor prefsEditor = mSharedPref.edit();
        prefsEditor.putString(key, value);
        prefsEditor.commit();
    }

    public static boolean read(String key, boolean defValue) {
        return mSharedPref.getBoolean(key, defValue);
    }

    public static void write(String key, boolean value) {
        SharedPreferences.Editor prefsEditor = mSharedPref.edit();
        prefsEditor.putBoolean(key, value);
        prefsEditor.commit();
    }

    public static Integer read(String key, int defValue) {
        return mSharedPref.getInt(key, defValue);
    }

    public static void write(String key, Integer value) {
        SharedPreferences.Editor prefsEditor = mSharedPref.edit();
        prefsEditor.putInt(key, value).commit();
    }
}

Simply call SharedPref.init() on MainActivity once

SharedPref.init(getApplicationContext());

To Write data

SharedPref.write(SharedPref.NAME, "XXXX");//save string in shared preference.
SharedPref.write(SharedPref.AGE, 25);//save int in shared preference.
SharedPref.write(SharedPref.IS_SELECT, true);//save boolean in shared preference.

To Read Data

String name = SharedPref.read(SharedPref.NAME, null);//read string in shared preference.
int age = SharedPref.read(SharedPref.AGE, 0);//read int in shared preference.
boolean isSelect = SharedPref.read(SharedPref.IS_SELECT, false);//read boolean in shared preference.

In the click event "this" is the a tag that was clicked

jQuery('.class1 a').click( function() {
   var divToSlide = $(this).parent().find(".class2");
   if (divToSlide.is(":hidden")) {
      divToSlide.slideDown("slow");
   } else {
      divToSlide.slideUp();
   }
});

There's multiple ways to get to the div though you could also use .siblings, .next etc

In bootstrap 4 it is much easier to have a border on the fieldset that blends with the legend. You don't need custom css to achieve it, it can be done like this:

<fieldset class="border p-2">
   <legend  class="w-auto">Your Legend</legend>
</fieldset>

which looks like this:

Go online before starting android studio. Then go file->New project Follow onscreen steps. Then wait It will download the necessary files over internet. And that should fix it.

Have you tried

here is a simple description of all:

• POST is always for creating a resource ( does not matter if it was duplicated )
• PUT is for checking if resource is exists then update , else create new resource
• PATCH is always for update a resource

The accepted answer from Paul is great. I've made a small extension to this which is very useful if you have an multidimensional array like this (which is quite common):

Array
(
    [0] => Array
        (
            [a] => "a"
            [b] => "b"
        )

    [1] => Array
        (
            [a] => "a2"
            [b] => "b2"
        )

    [2] => Array
        (
            [a] => "a3"
            [b] => "b3"
        )

    [3] => Array
        (
            [a] => "a4"
            [b] => "b4"
        )

    [4] => Array
        (
            [a] => "a5"
            [b] => "b5"
        )

)

So I just took Paul's function from above:

/**
  * Formats a line (passed as a fields  array) as CSV and returns the CSV as a string.
  * Adapted from http://us3.php.net/manual/en/function.fputcsv.php#87120
  */
function arrayToCsv( array &$fields, $delimiter = ';', $enclosure = '"', $encloseAll = false, $nullToMysqlNull = false ) {
    $delimiter_esc = preg_quote($delimiter, '/');
    $enclosure_esc = preg_quote($enclosure, '/');

    $output = array();
    foreach ( $fields as $field ) {
        if ($field === null && $nullToMysqlNull) {
            $output[] = 'NULL';
            continue;
        }

        // Enclose fields containing $delimiter, $enclosure or whitespace
        if ( $encloseAll || preg_match( "/(?:${delimiter_esc}|${enclosure_esc}|\s)/", $field ) ) {
            $output[] = $enclosure . str_replace($enclosure, $enclosure . $enclosure, $field) . $enclosure;
        }
        else {
            $output[] = $field;
        }
    }

    return implode( $delimiter, $output );
}

And added this:

function a2c($array, $glue = "\n")
{
    $ret = [];
    foreach ($array as $item) {
        $ret[] = arrayToCsv($item);
    }
    return implode($glue, $ret);
}

So you can just call:

$csv = a2c($array);

If you want a special line ending you can use the optional parameter "glue" for this.

YUI DataTable

I don't know if YUI DT has this feature but I won't be surprised if it does.

I have a simple answer to this problem. I created a thread to update the time. In the thread i run a while loop which gets the time and update it. Check the below code and do not forget to mark it as right answer.

from tkinter import *
from tkinter import *
import _thread
import time


def update():
    while True:
      t=time.strftime('%I:%M:%S',time.localtime())
      time_label['text'] = t



win = Tk()
win.geometry('200x200')

time_label = Label(win, text='0:0:0', font=('',15))
time_label.pack()


_thread.start_new_thread(update,())

win.mainloop()

I have a similar problem, but now I know the reason.

After we use git init, we should add a remote repository using

git remote add name url

Pay attention to the word name, if we change it to origin, then this problem will not happen.

Of course, if we change it to py, then using git pull py branch and git push py branch every time you pull and push something will also be OK.

//Pour inserer :
            $pdf = addslashes(file_get_contents($_FILES['inputname']['tmp_name']));
            $filetype = addslashes($_FILES['inputname']['type']);//pour le test 
            $namepdf = addslashes($_FILES['inputname']['name']);            
            if (substr($filetype, 0, 11) == 'application'){
            $mysqli->query("insert into tablepdf(pdf_nom,pdf)value('$namepdf','$pdf')");
            }
//Pour afficher :
            $row = $mysqli->query("SELECT * FROM tablepdf where id=(select max(id) from tablepdf)");
            foreach($row as $result){
                 $file=$result['pdf'];
            }
            header('Content-type: application/pdf');
            echo file_get_contents('data:application/pdf;base64,'.base64_encode($file));

php.js ( http://www.phpjs.org/ ) has a isset() function: http://phpjs.org/functions/isset:454

Quoting MSDN:

When SET XACT_ABORT is ON, if a Transact-SQL statement raises a run-time error, the entire transaction is terminated and rolled back. When SET XACT_ABORT is OFF, in some cases only the Transact-SQL statement that raised the error is rolled back and the transaction continues processing.

In practice this means that some of the statements might fail, leaving the transaction 'partially completed', and there might be no sign of this failure for a caller.

A simple example:

INSERT INTO t1 VALUES (1/0)    
INSERT INTO t2 VALUES (1/1)    
SELECT 'Everything is fine'

This code would execute 'successfully' with XACT_ABORT OFF, and will terminate with an error with XACT_ABORT ON ('INSERT INTO t2' will not be executed, and a client application will raise an exception).

As a more flexible approach, you could check @@ERROR after each statement (old school), or use TRY...CATCH blocks (MSSQL2005+). Personally I prefer to set XACT_ABORT ON whenever there is no reason for some advanced error handling.

The current way is to use the calendar class. It has the setLenient method that will validate the date and throw and exception if it is out of range as in your example.

Forgot to add: If you get a calendar instance and set the time using your date, this is how you get the validation.

Calendar cal = Calendar.getInstance();
cal.setLenient(false);
cal.setTime(yourDate);
try {
    cal.getTime();
}
catch (Exception e) {
  System.out.println("Invalid date");
}
