Try this example and you will understand also what is the difference between Associative Array and Object in JavaScript.

Associative Array

var a = new Array(1,2,3); 
a['key'] = 'experiment';
Array.isArray(a);

returns true

Keep in mind that a.length will be undefined, because length is treated as a key, you should use Object.keys(a).length to get the length of an Associative Array.

Object

var a = {1:1, 2:2, 3:3,'key':'experiment'}; 
Array.isArray(a)

returns false

JSON returns an Object ... could return an Associative Array ... but it is not like that

Jay Gilford's answer will work, but I think really the easiest way is to just slap a display: none; on a submit button in the form.

I was searching for similar solution. The replies here and the Tutorial on top is informative. I studied posts/blogs referred here to build mine successful. I am posting complete CMakeLists.txt worked for me. I guess, this would be helpful as a basic template for beginners.

You could try this:

$scope.testdata = [{ 'name': 'name,id' }, {'name':'someName,someId'}]
$scope.array= [];
angular.forEach($scope.testdata, function (value, key) {
    $scope.array.push({ 'name': value.name.split(',')[0], 'id': value.name.split(',')[1] });
});
console.log($scope.array)

This way you can save the data for later use and acces it by using an ng-repeat like this:

<div ng-repeat="item in array">{{item.name}}{{item.id}}</div>

I hope this helped someone,

Yes you have the syntax error. If you want to get your Javascript errors and printing statements in your logcat you must implement the onConsoleMessage(ConsoleMessage cm) method in your WebChromeClient. It gives the complete stack traces like Web console(Inspect element). Here is the method.

public boolean onConsoleMessage(ConsoleMessage cm) 
    {
        Log.d("Message", cm.message() + " -- From line "
                             + cm.lineNumber() + " of "
                             + cm.sourceId() );
        return true;
    }

After implementation you will get your Javascript errors and print statements (console.log) on your logcat.

Go with the mouse to the Windows Icon (lower left) and start typing "Anaconda". There should show up some matching entries. Select "Anaconda Prompt". A new command window, named "Anaconda Prompt" will open. Now, you can work from there with Python, conda and other tools.

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!

I added

config.EnableCors(new EnableCorsAttribute(Properties.Settings.Default.Cors, "", ""))

as well as

app.UseCors(CorsOptions.AllowAll);

on the server. This results in two header entries. Just use the latter one and it works.

Here is a solution which sorts the properties alphabetically and prints them all together with their values:

public void logProperties() throws IllegalArgumentException, IllegalAccessException {
  Class<?> aClass = this.getClass();
  Field[] declaredFields = aClass.getDeclaredFields();
  Map<String, String> logEntries = new HashMap<>();

  for (Field field : declaredFields) {
    field.setAccessible(true);

    Object[] arguments = new Object[]{
      field.getName(),
      field.getType().getSimpleName(),
      String.valueOf(field.get(this))
    };

    String template = "- Property: {0} (Type: {1}, Value: {2})";
    String logMessage = System.getProperty("line.separator")
            + MessageFormat.format(template, arguments);

    logEntries.put(field.getName(), logMessage);
  }

  SortedSet<String> sortedLog = new TreeSet<>(logEntries.keySet());

  StringBuilder sb = new StringBuilder("Class properties:");

  Iterator<String> it = sortedLog.iterator();
  while (it.hasNext()) {
    String key = it.next();
    sb.append(logEntries.get(key));
  }

  System.out.println(sb.toString());
}

The LINEST function described in a previous answer is the way to go, but an easier way to show the 3 coefficients of the output is to additionally use the INDEX function. In one cell, type: =INDEX(LINEST(B2:B21,A2:A21^{1,2},TRUE,FALSE),1) (by the way, the B2:B21 and A2:A21 I used are just the same values the first poster who answered this used... of course you'd change these ranges appropriately to match your data). This gives the X^2 coefficient. In an adjacent cell, type the same formula again but change the final 1 to a 2... this gives the X^1 coefficient. Lastly, in the next cell over, again type the same formula but change the last number to a 3... this gives the constant. I did notice that the three coefficients are very close but not quite identical to those derived by using the graphical trendline feature under the charts tab. Also, I discovered that LINEST only seems to work if the X and Y data are in columns (not rows), with no empty cells within the range, so be aware of that if you get a #VALUE error.

I have encountered with same issue. When I changed content type it has solved. I'm not sure this solution will help you but maybe it is. If you don't mind about content-type, it worked for me.

axios.defaults.headers.post['Content-Type'] ='application/x-www-form-urlencoded';

try to simply git restore .

That's what git says & it's working

Try this:

import time
while True:
    print("Hi ", end="\r")
    time.sleep(1)
    print("Bob", end="\r")
    time.sleep(1)

It worked for me. The end="\r" part is making it overwrite the previous line.

WARNING!

If you print out hi, then print out hello using \r, you’ll get hillo because the output wrote over the previous two letters. If you print out hi with spaces (which don’t show up here), then it will output hi. To fix this, print out spaces using \r.

In my case I was running Tensorflow Docker container in Ubuntu 20.04 :Run your docker container in One terminal , I ran it with

docker run -it od

And then started another terminal and ran below docker ps with sudo:

sudo docker ps

I successfully got container id:

CONTAINER ID        IMAGE               COMMAND             CREATED

The easiest way for me to convert a date was to stringify it then slice it.

var event = new Date("Fri Apr 05 2019 16:59:00 GMT-0700 (Pacific Daylight Time)");

let date = JSON.stringify(event)
date = date.slice(1,11)

// console.log(date) = '2019-04-05'

The task must be configured in two steps.

First you create a simple task that start at 0:00, every day. Then, you go in Advanced... (or similar depending on the operating system you are on) and select the Repeat every X minutes option for 24 hours.

The key here is to find the advanced properties. If you are using the XP wizard, it will only offer you to launch the advanced dialog once you created the task.

On more recent versions of Windows (7+ I think?):

1. Double click the task and a property window will show up.
2. Click the Triggers tab.
3. Double click the trigger details and the Edit Trigger window will show up.
4. Under Advanced settings panel, tick Repeat task every xxx minutes, and set Indefinitely if you need.
5. Finally, click ok.

In pseudocode:

split it by colon
seconds = 3600 * HH + 60 * MM + SS

You can use filters with -webkit-filter and filter: Filters are relatively new to browsers but supported in over 90% of browsers according to the following CanIUse table: https://caniuse.com/#feat=css-filters

You can change an image to grayscale, sepia and lot more (look at the example).

So you can now change the color of a PNG file with filters.

body {
    background-color:#03030a;
    min-width: 800px;
    min-height: 400px
}
img {
    width:20%;
    float:left; 
     margin:0;
}
/*Filter styles*/
.saturate { filter: saturate(3); }
.grayscale { filter: grayscale(100%); }
.contrast { filter: contrast(160%); }
.brightness { filter: brightness(0.25); }
.blur { filter: blur(3px); }
.invert { filter: invert(100%); }
.sepia { filter: sepia(100%); }
.huerotate { filter: hue-rotate(180deg); }
.rss.opacity { filter: opacity(50%); }

A slightly more practical/efficient plugin based on Ivan Castellanos' answer (which was based on M4N's answer). Using || 0 will convert Nan to 0 without the testing step.

I've also provided float and int variations to suit the intended use:

jQuery.fn.cssInt = function (prop) {
    return parseInt(this.css(prop), 10) || 0;
};

jQuery.fn.cssFloat = function (prop) {
    return parseFloat(this.css(prop)) || 0;
};

Usage:

$('#elem').cssInt('top');    // e.g. returns 123 as an int
$('#elem').cssFloat('top');  // e.g. Returns 123.45 as a float

This happens when you update from Chrome 55 to Chrome 56 (56.0.2924.87).
This is an increase in security enforcement.
It doesn't go away by restarting the browser, and it's not a bug.

Mountain View says it's hoping you don't ever encounter the message, because Certificate Authorities are required to stop issuing SHA-1 certificates in 2016. Just in case, Google plans to continue issuing warnings until Chrome completely stops supporting SHA-1 on January 1st, 2017. When that day comes, a website that still uses the function will trigger a fatal network error. (Source: Engadget.com)

If this happens, the most-likely cause is that your (or the website's) SSL-certificate uses SHA1.
SHA1 is broken, and SSL certificates using SHA1 are not secure anymore (it's now been a long time that Chrome showed this to you - now it blocks NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM).

Another likely cause is that your SSL-certificate expired
Also, you should disable backwards-compatiblity with SSL2 & SSL3 (Poodle Attack).
You should only be using TLS (SSL 3.1+).

To test your domain's SSL-certificate, you can use SSL labs SSL test.

To find out what exactly the issue is: Open the chrome developer console (CTRL + SHIFT + J OR F12) And change to the security tab

For more information:
https://support.google.com/chrome/answer/95617?visit_id=1-636221396724527190-3454695657&p=ui_security_indicator&rd=1

FYI:

SHA-1 has been growing weaker and more insecure everyday for a decade now, which is dangerous considering we tend to trust websites with "https://" in their URLs. Other browsers like Mozilla Firefox and Microsoft Edge also plan to stop supporting it in an effort to encourage website owners to switch to more secure SHA-2 certificates as soon as possible.

If you urgently need to get around it (you need to close all running instances of Chrome first - otherwise it won't work):

chrome --args --ignore-certificate-errors

Please note: don't go online-banking or gmail'ing with those command-line settings active in your Chrome instance.

I would think your own suggestion is correct, however the xml is not quite valid. If you are running the //book[title[@lang='it']] on <root>[Your"XML"Here]</root> then the free online xPath testers such as one here will find the expected result.

How about this one-liner?

var isAndroid = /(android)/i.test(navigator.userAgent);

The i modifier is used to perform case-insensitive matching.

Technique taken from Cordova AdMob test project: https://github.com/floatinghotpot/cordova-admob-pro/wiki/00.-How-To-Use-with-PhoneGap-Build

In recent Visual Studio Code versions you can find settings here:

Menu File → Preference → Settings → Text Editor → Files → (scroll down a bit) Trim Trailing Whitespace

This is for trimming whitespace when saving a file.

Or you can search "Trim Trailing Whitespace" in the top search bar.

Hope this helps, with Serverless framework you can do something like this:

1. Add these things in your serverless.yml file:

plugins: - serverless-webpack custom: webpackIncludeModules: forceInclude: - <your package name> (for example: node-fetch) 2. Then create your Lambda function, deploy it by serverless deploy, the package that included in serverless.yml will be there for you.

I was encountering the same problem. I had a Tooltip component that was receiving showTooltip prop, that I was updating on Parent component based on an if condition, it was getting updated in Parent component but Tooltip component was not rendering.

const Parent = () => {
   let showTooltip = false;
   if(....){ showTooltip = true; }
   return(
      <Tooltip showTooltip={showTooltip}></Tooltip>
   )
}

The mistake I was doing is to declare showTooltip as a let.

I realized what I was doing wrong I was violating the principles of how rendering works, Replacing it with hooks did the job.

const [showTooltip, setShowTooltip] =  React.useState<boolean>(false);

I don't like loops. Based on @Nathan Feger:

md5 = hashlib.md5()
with open(filename, 'rb') as f:
    functools.reduce(lambda _, c: md5.update(c), iter(lambda: f.read(md5.block_size * 128), b''), None)
md5.hexdigest()

Note: Avoid using python setup.py install use pip install .

You need to remove all files manually, and also undo any other stuff that installation did manually.

If you don't know the list of all files, you can reinstall it with the --record option, and take a look at the list this produces.

To record a list of installed files, you can use:

python setup.py install --record files.txt

Once you want to uninstall you can use xargs to do the removal:

xargs rm -rf < files.txt

Or if you're running Windows, use Powershell:

Get-Content files.txt | ForEach-Object {Remove-Item $_ -Recurse -Force}

Then delete also the containing directory, e.g. /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/my_module-0.1.egg/ on macOS. It has no files, but Python will still import an empty module:

>>> import my_module
>>> my_module.__file__
None

Once deleted, Python shows:

>>> import my_module
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'my_module'

For all the standard library types the member function empty() is a query, not a command, i.e. it means "are you empty?" not "please throw away your contents".

The clear() member function is inherited from ios and is used to clear the error state of the stream, e.g. if a file stream has the error state set to eofbit (end-of-file), then calling clear() will set the error state back to goodbit (no error).

For clearing the contents of a stringstream, using:

m.str("");

is correct, although using:

m.str(std::string());

is technically more efficient, because you avoid invoking the std::string constructor that takes const char*. But any compiler these days should be able to generate the same code in both cases - so I would just go with whatever is more readable.

I noticed that at least two proposed solutions don't handle overlapping search hits. I didn't check the one marked with the green checkmark. Here is one that handles overlapping search hits:

    public static List<int> GetPositions(this string source, string searchString)
    {
        List<int> ret = new List<int>();
        int len = searchString.Length;
        int start = -1;
        while (true)
        {
            start = source.IndexOf(searchString, start +1);
            if (start == -1)
            {
                break;
            }
            else
            {
                ret.Add(start);
            }
        }
        return ret;
    }

In your setup.py, if you have:

from distutils.core import setup

Then, change it to

from setuptools import setup

Then re-create your virtualenv and re-run the command, and it should work.

Method 1

One simple way to confirm is to use the native browser confirm alert. The template can have a button or link.

<button type=button class="btn btn-primary"  (click)="clickMethod('name')">Delete me</button>

And the component method can be something like below.

clickMethod(name: string) {
  if(confirm("Are you sure to delete "+name)) {
    console.log("Implement delete functionality here");
  }
}

Method 2

Another way to get a simple confirmation dialog is to use the angular bootstrap components like ng-bootstrap or ngx-bootstrap. You can simply install the component and use the modal component.

1. Examples of modals using ng-bootstrap
2. Examples of modals using ngx-bootstrap.

Method 3

Provided below is another way to implement a simple confirmation popup using angular2/material that I implemented in my project.

app.module.ts

import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { ConfirmationDialog } from './confirm-dialog/confirmation-dialog';

@NgModule({
  imports: [
    ...
    FormsModule,
    ReactiveFormsModule
  ],
  declarations: [
    ...
    ConfirmationDialog
  ],
  providers: [ ... ],
  bootstrap: [ AppComponent ],
  entryComponents: [ConfirmationDialog]
})
export class AppModule { }

confirmation-dialog.ts

import { Component, Input } from '@angular/core';
import { MdDialog, MdDialogRef } from '@angular/material';

@Component({
  selector: 'confirm-dialog',
  templateUrl: '/app/confirm-dialog/confirmation-dialog.html',
})
export class ConfirmationDialog {
  constructor(public dialogRef: MdDialogRef<ConfirmationDialog>) {}

  public confirmMessage:string;
}

confirmation-dialog.html

<h1 md-dialog-title>Confirm</h1>
<div md-dialog-content>{{confirmMessage}}</div>
<div md-dialog-actions>
  <button md-button style="color: #fff;background-color: #153961;" (click)="dialogRef.close(true)">Confirm</button>
  <button md-button (click)="dialogRef.close(false)">Cancel</button>
</div>

app.component.html

<button (click)="openConfirmationDialog()">Delete me</button>

app.component.ts

import { MdDialog, MdDialogRef } from '@angular/material';
import { ConfirmationDialog } from './confirm-dialog/confirmation-dialog';

@Component({
  moduleId: module.id,
  templateUrl: '/app/app.component.html',
  styleUrls: ['/app/main.css']
})

export class AppComponent implements AfterViewInit {
  dialogRef: MdDialogRef<ConfirmationDialog>;

  constructor(public dialog: MdDialog) {}

  openConfirmationDialog() {
    this.dialogRef = this.dialog.open(ConfirmationDialog, {
      disableClose: false
    });
    this.dialogRef.componentInstance.confirmMessage = "Are you sure you want to delete?"

    this.dialogRef.afterClosed().subscribe(result => {
      if(result) {
        // do confirmation actions
      }
      this.dialogRef = null;
    });
  }
}

index.html => added following stylesheet

<link rel="stylesheet" href="node_modules/@angular/material/core/theming/prebuilt/indigo-pink.css">

    @Scripts.Render("~/bundles/jquery")

I moved them above the @RenderBody() and all was fine.

    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/bootstrap")
    @RenderSection("scripts", required: false)

    <div class="container body-content">
        @RenderBody()
        <hr />
        <footer>
            <p>&copy; @DateTime.Now.Year - My ASP.NET Application</p>
        </footer>
    </div>

First You have to use this code in MainActivity.java class

@Override
public void onClick(View v)
{
    // TODO Auto-generated method stub
    Intent i = new Intent(getApplicationContext(),NextActivity.class);
    startActivity(i);

}

You can pass intent this way.

Second

add proper entry into manifest.xml file.

<activity android:name=".NextActivity" />

Now see what happens.

TextPad has a free xmltidy plugin that pretty-prints your XML. Nice and fast, although TextPad is shareware.

one more if you want to switch IE 8 page render in IE 8 standard mode

<meta http-equiv="X-UA-Compatible" content="IE=100" /> <!-- IE8 mode -->

The typical command is:

docker container ls -f 'status=exited'

However, this will only list one of the possible non-running statuses. Here's a list of all possible statuses:

• created
• restarting
• running
• removing
• paused
• exited
• dead

You can filter on multiple statuses by passing multiple filters on the status:

docker container ls -f 'status=exited' -f 'status=dead' -f 'status=created'

If you are integrating this with an automatic cleanup script, you can chain one command to another with some bash syntax, output just the container id's with -q, and you can also limit to just the containers that exited successfully with an exit code filter:

docker container rm $(docker container ls -q -f 'status=exited' -f 'exited=0')

For more details on filters you can use, see Docker's documentation: https://docs.docker.com/engine/reference/commandline/ps/#filtering

Swift 3/4

You can use the below extension for your convenience.

Usage inside a ViewController:

showInputDialog(title: "Add number",
                subtitle: "Please enter the new number below.",
                actionTitle: "Add",
                cancelTitle: "Cancel",
                inputPlaceholder: "New number",
                inputKeyboardType: .numberPad)
{ (input:String?) in
    print("The new number is \(input ?? "")")
}

The extension code:

extension UIViewController {
    func showInputDialog(title:String? = nil,
                         subtitle:String? = nil,
                         actionTitle:String? = "Add",
                         cancelTitle:String? = "Cancel",
                         inputPlaceholder:String? = nil,
                         inputKeyboardType:UIKeyboardType = UIKeyboardType.default,
                         cancelHandler: ((UIAlertAction) -> Swift.Void)? = nil,
                         actionHandler: ((_ text: String?) -> Void)? = nil) {

        let alert = UIAlertController(title: title, message: subtitle, preferredStyle: .alert)
        alert.addTextField { (textField:UITextField) in
            textField.placeholder = inputPlaceholder
            textField.keyboardType = inputKeyboardType
        }
        alert.addAction(UIAlertAction(title: actionTitle, style: .default, handler: { (action:UIAlertAction) in
            guard let textField =  alert.textFields?.first else {
                actionHandler?(nil)
                return
            }
            actionHandler?(textField.text)
        }))
        alert.addAction(UIAlertAction(title: cancelTitle, style: .cancel, handler: cancelHandler))

        self.present(alert, animated: true, completion: nil)
    }
}

SELECT *
FROM   B
WHERE  NOT EXISTS (SELECT 1 
                   FROM   A 
                   WHERE  A.ID = B.ID)

There is here someone telling about this feature in sql 2011, its sad they choose a little different keyword "OFFSET / FETCH" but its not standart then ok.

For the lads using TypeScript and those who don't want to deal with string prototypes, here is a typescript version of Ed.'s answer:

    // Usage example:
    "Some string".replace(/[^a-zA-Z0-9-_]/g, char => ToLatinMap.get(char) || '')

    // Map:
    export let ToLatinMap: Map<string, string> = new Map<string, string>([

You don't need to run any docker commands as sudo when you're using boot2docker as every command passed into the boot2docker VM runs as root by default.

You're seeing the error when you're running as sudo because sudo doesn't have the DOCKER_HOST env set, only your user does.

You can confirm this by doing a:

$ env

Then a

$ sudo env

And looking for DOCKER_HOST in each output.

As for having a docker file that runs your script, something like this might work for you:

Dockerfile

FROM busybox

# Copy your script into the docker image
ADD /path/to/your/script.sh /usr/local/bin/script.sh

# Run your script
CMD /usr/local/bin/script.sh

Then you can run:

docker build -t your-image-name:your-tag .

This will build your docker image, which you can see by doing a:

docker images

Then, to run your container, you can do a:

docker run your-image-name:your-tag

This run command will start a container from the image you created with your Dockerfile and your build command and then it will finish once your script.sh has finished executing.

If you are using cmake, you can use:

add_compile_options(-pthread)

Or

SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread")

Yes:

RelativeLayout.LayoutParams params= new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT); 
params.addRule(RelativeLayout.BELOW, R.id.below_id);
viewToLayout.setLayoutParams(params);

First, the code creates a new layout params by specifying the height and width. The addRule method adds the equivalent of the xml properly android:layout_below. Then you just call View#setLayoutParams on the view you want to have those params.

Works Perfect

format(5.59, '.1f') # to display
float(format(5.59, '.1f')) #to round

Standard class java.util.ArrayList is resizable array, growing when new elements added.

These might resolve the issue(It did for me). In IIS Express change the project property values, "Anonymous Authentication" and "Windows Authentication". To do this, when project is selected, press F4 and then change these properties.

In case you are deploying it on IIS locally, make sure local machines "Windows Authentication" feature is enabled and "Anonymous Authentication" is disabled.

Refer to

https://grekai.wordpress.com/2011/03/31/httpcontext-current-user-identity-name-is-empty/

#include <stdio.h>
#include <string.h>

int main(void){
    char word[17], outword[33];//17:16+1, 33:16*2+1
    int i, len;

    printf("Intro word:");
    fgets(word, sizeof(word), stdin);
    len = strlen(word);
    if(word[len-1]=='\n')
        word[--len] = '\0';

    for(i = 0; i<len; i++){
        sprintf(outword+i*2, "%02X", word[i]);
    }
    printf("%s\n", outword);
    return 0;
}

I don't understand why the other friends tell you use HH, But after I test so many time, The correct 24 hour format is :

hh

.

I see it from : http://www.malot.fr/bootstrap-datetimepicker/

I don't know why they don't use the common type HH for 24 hour.....

I hope anyone could tell me if I'm wrong.....

Try webfs, it's tiny and doesn't depend on having a platform like node.js or python installed.

You should create a bound scope variable and watch its changes:

return {
   restrict: 'E',
   scope: {
     name: '='
   },
   link: function(scope) {
     scope.$watch('name', function() {
        // all the code here...
     });
   }
};

Setting remote repository URL worked for me:

git remote set-url origin https://github.com/path-to-repo/MyRepo.git

You can use Len(StrFile) > 0 in loop check statement !

Sub openMyfile()

    Dim Source As String
    Dim StrFile As String

    'do not forget last backslash in source directory.
    Source = "E:\Planning\03\"
    StrFile = Dir(Source)

    Do While Len(StrFile) > 0                        
        Workbooks.Open Filename:=Source & StrFile
        StrFile = Dir()
    Loop
End Sub

The class below should do the trick. Just create an instance, call the "multiply" method, and provide the source input stream and the amount of duplicates you need.

Important: you must consume all cloned streams simultaneously in separate threads.

package foo.bar;

import java.io.IOException;
import java.io.InputStream;
import java.io.PipedInputStream;
import java.io.PipedOutputStream;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class InputStreamMultiplier {
    protected static final int BUFFER_SIZE = 1024;
    private ExecutorService executorService = Executors.newCachedThreadPool();

    public InputStream[] multiply(final InputStream source, int count) throws IOException {
        PipedInputStream[] ins = new PipedInputStream[count];
        final PipedOutputStream[] outs = new PipedOutputStream[count];

        for (int i = 0; i < count; i++)
        {
            ins[i] = new PipedInputStream();
            outs[i] = new PipedOutputStream(ins[i]);
        }

        executorService.execute(new Runnable() {
            public void run() {
                try {
                    copy(source, outs);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        });

        return ins;
    }

    protected void copy(final InputStream source, final PipedOutputStream[] outs) throws IOException {
        byte[] buffer = new byte[BUFFER_SIZE];
        int n = 0;
        try {
            while (-1 != (n = source.read(buffer))) {
                //write each chunk to all output streams
                for (PipedOutputStream out : outs) {
                    out.write(buffer, 0, n);
                }
            }
        } finally {
            //close all output streams
            for (PipedOutputStream out : outs) {
                try {
                    out.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

__dirname 

Gives you the current node application's rooth directory.

In your case, you'd use

__dirname + '/Desktop/MyApp/newversion/partials/navigation.jade';

See this answer:

App base path from a module in NodeJS

try this is your activity onCreate:

ScrollView sView = (ScrollView)findViewById(R.id.deal_web_view_holder);
// Hide the Scollbar
sView.setVerticalScrollBarEnabled(false);
sView.setHorizontalScrollBarEnabled(false);

http://developer.android.com/reference/android/view/View.html#setVerticalScrollBarEnabled%28boolean%29

In my case the error got resolved by migrating to OpenCV 4.0 (or higher).

When I had this problem I could see only a part of my text and this is the solution for that:

Be sure to set the AutoSize property to true.

output.AutoSize = true;

To delete all images :

docker rmi $(docker images -a -q)

where -a is all, and -q is return only image ids

To remove unused images, and containers :

docker system prune

beware as if you are using docker swarm, and your local machine is joining remote swarm (as manager/worker), your local will be the deployed repo. executing this thus removes the deployed images.

It's not exactly an operator, rather a keyword. And no, it doesn't do any runtime-magic.

ALLOW-FROM is not supported in Chrome or Safari. See MDN article: https://developer.mozilla.org/en-US/docs/Web/HTTP/X-Frame-Options

You are already doing the work to make a custom header and send it with the correct data, can you not just exclude the header when you detect it is from a valid partner and add DENY to every other request? I don't see the benefit of AllowFrom when you are already dynamically building the logic up?

Using file extension and getimagesize function to detect if uploaded file has right format is just the entry level check and it can simply bypass by uploading a file with true extension and some byte of an image header but wrong content.

for being secure and safe you may make thumbnail/resize (even with original image sizes) the uploaded picture and save this version instead the uploaded one. Also its possible to get uploaded file content and search it for special character like <?php to find the file is image or not.

This is the full thing

binary = input('enter a number: ')
decimal = 0
for digit in binary:
decimal= decimal*2 + int(digit)

print (decimal)

Try changing the name of the variable as sometimes it clashes with other modules/subs

I can't remember if it works with Sheet

While C++ (excluding C++11) has enums, the values in them are "leaked" into the global namespace.
If you don't want to have them leaked (and don't NEED to use the enum type), consider the following:

class EnumName {  
   public:   
      static int EnumVal1;  
      (more definitions)  
};  
EnumName::EnumVal1 = {value};  
if ([your value] == EnumName::EnumVal1)  ...

jQuery

$(function() {
    $("td[colspan=3]").find("div").hide();
    $("tr").click(function(event) {
        var $target = $(event.target);
        $target.closest("tr").next().find("div").slideToggle();                
    });
});

HTML

<table>
    <thead>
        <tr>
            <th>one</th><th>two</th><th>three</th>
        </tr>
    </thead>
    <tbody>

        <tr>
            <td><p>data<p></td><td>data</td><td>data</td>
        </tr>
        <tr>
            <td colspan="3">
                <div>
                    <table>
                            <tr>
                                <td>data</td><td>data</td>
                            </tr>
                    </table>
                </div>
            </td>
        </tr>
    </tbody>
</table>

This is much like a previous example above. I found when trying to implement that example that if the table row to be expanded was clicked while it was not expanded it would disappear, and it would no longer be expandable

To fix that I simply removed the ability to click the expandable element for slide up and made it so that you can only toggle using the above table row.

I also made some minor changes to HTML and corresponding jQuery.

NOTE: I would have just made a comment but am not allowed to yet therefore the long post. Just wanted to post this as it took me a bit to figure out what was happening to the disappearing table row.

Essentially, PHPStorm = WebStorm + PHP, SQL and more.

BUT (and this is a very important "but") because it is capable of parsing so much more, it quite often fails to parse Node.js dependencies, as they (probably) conflict with some other syntax it is capable of parsing.

The most notable example of that would be Mongoose model definition, where WebStorm easily recognizes mongoose.model method, whereas PHPStorm marks it as unresolved as soon as you connect Node.js plugin.

Surprisingly, it manages to resolve the method if you turn the plugin off, but leave the core modules connected, but then it cannot be used for debugging. And this happens to quite a few methods out there.

All this goes for PHPStorm 8.0.1, maybe in later releases this annoying bug would be fixed.

for key in data.keys():
    print key

Using Java:

WebElement webElement = driver.findElement(By.xpath(""));//You can use xpath, ID or name whatever you like
webElement.sendKeys(Keys.TAB);
webElement.sendKeys(Keys.ENTER);

this error is also caused by null pointer reference. if you are using a pointer who is not initialized then it causes this error.

to check either a pointer is initialized or not you can try something like

Class *pointer = new Class();
if(pointer!=nullptr){
    pointer->myFunction();
}

Simple solution:

<iframe onload="this.style.height=this.contentWindow.document.body.scrollHeight + 'px';" ...></iframe>

This works when the iframe and parent window are in the same domain. It does not work when the two are in different domains.

Using obtrusive JavaScript (i.e. inline code) as in your example, you can attach the click event handler to the div element with the onclick attribute like so:

 <div id="some-id" class="some-class" onclick="slideonlyone('sms_box');">
     ...
 </div>

However, the best practice is unobtrusive JavaScript which you can easily achieve by using jQuery's on() method or its shorthand click(). For example:

 $(document).ready( function() {
     $('.some-class').on('click', slideonlyone('sms_box'));
     // OR //
     $('.some-class').click(slideonlyone('sms_box'));
 });

Inside your handler function (e.g. slideonlyone() in this case) you can reference the element that triggered the event (e.g. the div in this case) with the $(this) object. For example, if you need its ID, you can access it with $(this).attr('id').

EDIT

After reading your comment to @fmsf below, I see you also need to dynamically reference the target element to be toggled. As @fmsf suggests, you can add this information to the div with a data-attribute like so:

<div id="some-id" class="some-class" data-target="sms_box">
    ...
</div>

To access the element's data-attribute you can use the attr() method as in @fmsf's example, but the best practice is to use jQuery's data() method like so:

 function slideonlyone() {
     var trigger_id = $(this).attr('id'); // This would be 'some-id' in our example
     var target_id  = $(this).data('target'); // This would be 'sms_box'
     ...
 }

Note how data-target is accessed with data('target'), without the data- prefix. Using data-attributes you can attach all sorts of information to an element and jQuery would automatically add them to the element's data object.

Try to use IF(condition, value1, value2)

SELECT ID, HEADING, 
IF(action_type='Income',action_amount,0) as Income,
IF(action_type='Expense',action_amount,0) as Expense

And if you need to style your form elements according to it's state (modified/not modified) dynamically or to test whether some values has actually changed, you can use the following module, developed by myself: https://github.com/betsol/angular-input-modified

It adds additional properties and methods to the form and it's child elements. With it, you can test whether some element contains new data or even test if entire form has new unsaved data.

You can setup the following watch: $scope.$watch('myForm.modified', handler) and your handler will be called if some form elements actually contains new data or if it reversed to initial state.

Also, you can use modified property of individual form elements to actually reduce amount of data sent to a server via AJAX call. There is no need to send unchanged data.

As a bonus, you can revert your form to initial state via call to form's reset() method.

You can find the module's demo here: http://plnkr.co/edit/g2MDXv81OOBuGo6ORvdt?p=preview

To adjust the length of the samples:

set key samplen X

(default is 4)

To adjust the vertical spacing of the samples:

set key spacing X

(default is 1.25)

and (for completeness), to adjust the fontsize:

set key font "<face>,<size>"

(default depends on the terminal)

And of course, all these can be combined into one line:

set key samplen 2 spacing .5 font ",8"

Note that you can also change the position of the key using set key at <position> or any one of the pre-defined positions (which I'll just defer to help key at this point)

Why do you get these ^M in your git diff?

In my case I was working on a project which was developed in Windows and I used OS X. When I changed some code, I saw ^M at the end of the lines I added in git diff. I think the ^M were showing up because they were different line endings than the rest of the file. Because the rest of the file was developed in Windows it used CR line endings, and in OS X it uses LF line endings.

Apparently, the Windows developer didn't use the option "Checkout Windows-style, commit Unix-style line endings" during the installation of Git.

So what should we do about this?

You can have the Windows users reinstall git and use the "Checkout Windows-style, commit Unix-style line endings" option. This is what I would prefer, because I see Windows as an exception in its line ending characters and Windows fixes its own issue this way.

If you go for this option, you should however fix the current files (because they're still using the CR line endings). I did this by following these steps:

1. Remove all files from the repository, but not from your filesystem.

   git rm --cached -r .
   

2. Add a .gitattributes file that enforces certain files to use a LF as line endings. Put this in the file:

   *.ext text eol=crlf
   

   Replace .ext with the file extensions you want to match.

3. Add all the files again.

   git add .
   

   This will show messages like this:

   warning: CRLF will be replaced by LF in <filename>.
   The file will have its original line endings in your working directory.
   

4. You could remove the .gitattributes file unless you have stubborn Windows users that don't want to use the "Checkout Windows-style, commit Unix-style line endings" option.

5. Commit and push it all.

6. Remove and checkout the applicable files on all the systems where they're used. On the Windows systems, make sure they now use the "Checkout Windows-style, commit Unix-style line endings" option. You should also do this on the system where you executed these tasks because when you added the files git said:

   The file will have its original line endings in your working directory.
   

   You can do something like this to remove the files:

   git ls | grep ".ext$" | xargs rm -f
   

   And then this to get them back with the correct line endings:

   git ls | grep ".ext$" | xargs git checkout
   

   Of course replacing .ext with the extension you want.

Now your project only uses LF characters for the line endings, and the nasty CR characters won't ever come back :).

The other option is to enforce windows style line endings. You can also use the .gitattributes file for this.

There is nothing "dirty" about using try-except clause. This is the pythonic way. ValueError will be raised by the .index method only, because it's the only code you have there!

To answer the comment:
In Python, easier to ask forgiveness than to get permission philosophy is well established, and no index will not raise this type of error for any other issues. Not that I can think of any.

ToString can take a format. try:

i.ToString("000");

I generally use Date if possible. Although it is mutable, the mutators are actually deprecated. In the end it basically wraps a long that would represent the date/time. Conversely, I would use Calendars if I have to manipulate the values.

You can think of it this way: you only use StringBuffer only when you need to have Strings that you can easily manipulate and then convert them into Strings using toString() method. In the same way, I only use Calendar if I need to manipulate temporal data.

For best practice, I tend to use immutable objects as much as possible outside of the domain model. It significantly reduces the chances of any side effects and it is done for you by the compiler, rather than a JUnit test. You use this technique by creating private final fields in your class.

And coming back to the StringBuffer analogy. Here is some code that shows you how to convert between Calendar and Date

String s = "someString"; // immutable string
StringBuffer buf = new StringBuffer(s); // mutable "string" via StringBuffer
buf.append("x");
assertEquals("someStringx", buf.toString()); // convert to immutable String

// immutable date with hard coded format.  If you are hard
// coding the format, best practice is to hard code the locale
// of the format string, otherwise people in some parts of Europe
// are going to be mad at you.
Date date =     new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH).parse("2001-01-02");

// Convert Date to a Calendar
Calendar cal = Calendar.getInstance();
cal.setTime(date);

// mutate the value
cal.add(Calendar.YEAR, 1);

// convert back to Date
Date newDate = cal.getTime();

// 
assertEquals(new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH).parse("2002-01-02"), newDate);

2015 Update

It is an old question but other new questions like:

• How to validate if a string is a valid date in js

get closed as duplicates of this one, so I think it's important to add some fresh info here. I'm writing it because I got scared thinking that people actually copy and paste some of the code posted here and use it in production.

Most of the answers here either use some complex regular expressions that match only some very specific formats and actually do it incorrectly (like matching January 32nd while not matching actual ISO date as advertised - see demo) or they try to pass anything to the Date constructor and wish for the best.

Using Moment

As I explained in this answer there is currently a library available for that: Moment.js

It is a library to parse, validate, manipulate, and display dates in JavaScript, that has a much richer API than the standard JavaScript date handling functions.

It is 12kB minified/gzipped and works in Node.js and other places:

bower install moment --save # bower
npm install moment --save   # npm
Install-Package Moment.js   # NuGet
spm install moment --save   # spm
meteor add momentjs:moment  # meteor

Using Moment you can be very specific about checking valid dates. Sometimes it is very important to add some clues about the format that you expect. For example, a date such as 06/22/2015 looks like a valid date, unless you use a format DD/MM/YYYY in which case this date should be rejected as invalid. There are few ways how you can tell Moment what format you expect, for example:

moment("06/22/2015", "MM/DD/YYYY", true).isValid(); // true
moment("06/22/2015", "DD/MM/YYYY", true).isValid(); // false

The true argument is there so the Moment won't try to parse the input if it doesn't exactly conform to one of the formats provided (it should be a default behavior in my opinion).

You can use an internally provided format:

moment("2015-06-22T13:17:21+0000", moment.ISO_8601, true).isValid(); // true

And you can use multiple formats as an array:

var formats = [
    moment.ISO_8601,
    "MM/DD/YYYY  :)  HH*mm*ss"
];
moment("2015-06-22T13:17:21+0000", formats, true).isValid(); // true
moment("06/22/2015  :)  13*17*21", formats, true).isValid(); // true
moment("06/22/2015  :(  13*17*21", formats, true).isValid(); // false

See: DEMO.

Other libraries

If you don't want to use Moment.js, there are also other libraries:

• XDate
• DateJS

2016 Update

I created the immoment module that is like (a subset of) Moment but without surprises caused by mutation of existing objects (see the docs for more info).

2018 Update

Today I recommend using Luxon for date/time manipulation instead of Moment, which (unlike Moment) makes all object immutable so there are no nasty surprises related to implicit mutation of dates.

Bottom line

Of course anyone can try to reinvent the wheel, write a regular expression (but please actually read ISO 8601 and RFC 3339 before you do it) or call buit-in constructors with random data to parse error messages like 'Invalid Date' (Are you sure this message is exactly the same on all platforms? In all locales? In the future?) or you can use a tested solution and use your time to improve it, not reinvent it. All of the libraries listed here are open source, free software.

A C++ identifier is a name used to identify a variable, function, class, module, or any other user-defined item. In C++ all names have to be declared before they are used. If you try to use the name of a such that hasn't been declared you will get an "undeclared identifier" compile-error.

According to the documentation, the declaration of printf() is in cstdio i.e. you have to include it, before using the function.

Create screen from Terminal:

screen -S <screen_name>

To see list of screens:

<screen -ls> or <screen -list>

To go to particular screen:

<screen -x screen_name>

<screen -r screen_name>

Inside screen

To Terminate screen:

give ctrl+d screen will get terminated

To Detach screen:

 give <ctrl+ad>or <screen -d >screen will get detached

To reattach screen:

screen -x <screen_name> or screen -r <screen_name>

To kill a screen from Terminal:

<screen -X -S screen_name quit> 

or

<screen -X -S screen_name kill>

You can use screen_name or process_id to execute commands.

If you use bootstrap just add form-control class. For example:

class="form-control" 

I think documentation has a great explanation of else, continue

[...] it is executed when the loop terminates through exhaustion of the list (with for) or when the condition becomes false (with while), but not when the loop is terminated by a break statement."

Source: Python 2 docs: Tutorial on control flow

By example:

# select distinct code from Platform where id in ( select platform__id from Build where product=p)
pl_ids = Build.objects.values('platform__id').filter(product=p)
platforms = Platform.objects.values_list('code', flat=True).filter(id__in=pl_ids).distinct('code')
platforms = list(platforms) if platforms else []

Note that you can still do:

s[0] = 'h';
s[1] = 'e';
s[2] = 'l';
s[3] = 'l';
s[4] = 'o';
s[5] = '\0';

When people talk about HTML5 applications they're most likely talking about writing just a simple web page or embedding a web page into their app (which will essentially provide the user interface). For the later there are different frameworks available, e.g. PhoneGap. These are used to provide more than the default browser features (e.g. multi touch) as well as allowing the app to run seamingly "standalone" and without the browser's navigation bars etc.

PHP is not what you are looking for, check out mod_rewrite

Turn off your firewall for port 80 from any address. Turn off 443 if you need https (SSL) access. Open the configuration file (http.conf) and find the lines that say:

Allow from 127.0.0.1

Change them to read

Allow from all

Restart the wampserver. It will now work. Enjoy!!

By default, the query log is disabled in Laravel 5: https://github.com/laravel/framework/commit/e0abfe5c49d225567cb4dfd56df9ef05cc297448

You will need to enable the query log by calling:

DB::enableQueryLog();

// and then you can get query log

dd(DB::getQueryLog());

or register an event listener:

DB::listen(
    function ($sql, $bindings, $time) {
        //  $sql - select * from `ncv_users` where `ncv_users`.`id` = ? limit 1
        //  $bindings - [5]
        //  $time(in milliseconds) - 0.38 
    }
);  

Some Tips

1. Multiple DB connections

If you have more than one DB connection you must specify which connection to log

To enables query log for my_connection:

DB::connection('my_connection')->enableQueryLog();

To get query log for my_connection:

print_r(
   DB::connection('my_connection')->getQueryLog()
);

2. Where to enable query log ?

class BeforeAnyDbQueryMiddleware
{
    public function handle($request, Closure $next)
    {
        DB::enableQueryLog();
        return $next($request);
    }

    public function terminate($request, $response)
    {
        // Store or dump the log data...
        dd(
            DB::getQueryLog()
        );
    }
}

A middleware's chain will not run for artisan commands, so for CLI execution you can enable query log in the artisan.start event listener.

For example you can put it in the bootstrap/app.php file

$app['events']->listen('artisan.start', function(){
    \DB::enableQueryLog();
});

3. Memory

Laravel keeps all queries in memory. So in some cases, such as when inserting a large number of rows, or having a long running job with a lot of queries, this can cause the application to use excess memory.

In most cases you will need the query log only for debugging, and if that is the case I would recommend you enable it only for development.

if (App::environment('local')) {
    // The environment is local
    DB::enableQueryLog();
}

You cannot run .py files from JavaScript without the Python program like you cannot open .txt files without a text editor. But the whole thing becomes a breath with a help of a Web API Server (IIS in the example below).

1. Install python and create a sample file test.py

   import sys
   # print sys.argv[0] prints test.py
   # print sys.argv[1] prints your_var_1
   
   def hello():
       print "Hi" + " " + sys.argv[1]
   
   if __name__ == "__main__":
       hello()
   

2. Create a method in your Web API Server

   [HttpGet]
   public string SayHi(string id)
   {
       string fileName = HostingEnvironment.MapPath("~/Pyphon") + "\\" + "test.py";          
   
       Process p = new Process();
       p.StartInfo = new ProcessStartInfo(@"C:\Python27\python.exe", fileName + " " + id)
       {
           RedirectStandardOutput = true,
           UseShellExecute = false,
           CreateNoWindow = true
       };
       p.Start();
   
       return p.StandardOutput.ReadToEnd();                  
   }
   

3. And now for your JavaScript:

   function processSayingHi() {          
      var your_param = 'abc';
      $.ajax({
          url: '/api/your_controller_name/SayHi/' + your_param,
          type: 'GET',
          success: function (response) {
              console.log(response);
          },
          error: function (error) {
              console.log(error);
          }
       });
   }
   

Remember that your .py file won't run on your user's computer, but instead on the server.

You don't have to repeat those format identifiers . For yyyy you just need to have Y, etc.

gmdate('Y-m-d h:i:s \G\M\T', time());

In fact you don't even need to give it a default time if you want current time

gmdate('Y-m-d h:i:s \G\M\T');  // This is fine for your purpose

There are several steps when using OpenSSL. You must have an SSL certificate made which can contain the certificate with the private key be sure to specify the exact location of the certificate (this example has it in the root). There are a lot of good tutorials out there.

• Some documentation and tools from HP (see chapter 2)
• Command line for OpenSSL

Some includes:

#include <openssl/applink.c>
#include <openssl/bio.h>
#include <openssl/ssl.h>
#include <openssl/err.h>

You will need to initialize OpenSSL:

void InitializeSSL()
{
    SSL_load_error_strings();
    SSL_library_init();
    OpenSSL_add_all_algorithms();
}

void DestroySSL()
{
    ERR_free_strings();
    EVP_cleanup();
}

void ShutdownSSL()
{
    SSL_shutdown(cSSL);
    SSL_free(cSSL);
}

Now for the bulk of the functionality. You may want to add a while loop on connections.

int sockfd, newsockfd;
SSL_CTX *sslctx;
SSL *cSSL;

InitializeSSL();
sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd< 0)

ssl_err = SSL_accept(cSSL);

You are then able read or write using:

SSL_read(cSSL, (char *)charBuffer, nBytesToRead);
SSL_write(cSSL, "Hi :3\n", 6);

Update The SSL_CTX_new should be called with the TLS method that best fits your needs in order to support the newer versions of security, instead of SSLv23_server_method(). See: OpenSSL SSL_CTX_new description

TLS_method(), TLS_server_method(), TLS_client_method(). These are the general-purpose version-flexible SSL/TLS methods. The actual protocol version used will be negotiated to the highest version mutually supported by the client and the server. The supported protocols are SSLv3, TLSv1, TLSv1.1, TLSv1.2 and TLSv1.3.

MYISAM:

1. MYISAM supports Table-level Locking
2. MyISAM designed for need of speed
3. MyISAM does not support foreign keys hence we call MySQL with MYISAM is DBMS
4. MyISAM stores its tables, data and indexes in diskspace using separate three different files. (tablename.FRM, tablename.MYD, tablename.MYI)
5. MYISAM not supports transaction. You cannot commit and rollback with MYISAM. Once you issue a command it’s done.
6. MYISAM supports fulltext search
7. You can use MyISAM, if the table is more static with lots of select and less update and delete.

INNODB:

1. InnoDB supports Row-level Locking
2. InnoDB designed for maximum performance when processing high volume of data
3. InnoDB support foreign keys hence we call MySQL with InnoDB is RDBMS
4. InnoDB stores its tables and indexes in a tablespace
5. InnoDB supports transaction. You can commit and rollback with InnoDB

It work for me

$request = new Request();
$request->headers->set('content-type', 'application/json');     
$request->initialize(['yourParam' => 2]);

check output

$queryParams = $request->query();
dd($queryParams['yourParam']); // 2

You are running your HTML from a different host than the host you are requesting. Because of this, you are getting blocked by the same origin policy.

One way around this is to use JSONP. This allows cross-site requests.

In JSON, you are returned:

{a: 5, b: 6}

In JSONP, the JSON is wrapped in a function call, so it becomes a script, and not an object.

callback({a: 5, b: 6})

You need to edit your REST service to accept a parameter called callback, and then to use the value of that parameter as the function name. You should also change the content-type to application/javascript.

For example: http://localhost:8080/restws/json/product/get?callback=process should output:

process({a: 5, b: 6})

In your JavaScript, you will need to tell jQuery to use JSONP. To do this, you need to append ?callback=? to the URL.

$.getJSON("http://localhost:8080/restws/json/product/get?callback=?",
   function(data) {
     alert(data);         
   });

If you use $.ajax, it will auto append the ?callback=? if you tell it to use jsonp.

$.ajax({ 
   type: "GET",
   dataType: "jsonp",
   url: "http://localhost:8080/restws/json/product/get",
   success: function(data){        
     alert(data);
   }
});

Here is an article on how to check and or install new patches :

To find the OPatch tool setup your database enviroment variables and then issue this comand:

cd $ORACLE_HOME/OPatch 
> pwd
/oracle/app/product/10.2.0/db_1/OPatch

To list all the patches applies to your database use the lsinventory option:

OPatch succeeded.

To list the patches using sql :

select * from registry$history;

I faced the same problem,but after hours of efforts i find the solution.It can be without using any external plugin:)

applicantListToExport: function (query, callback) {
  this
   .find(query).select({'advtId': 0})
   .populate({
      path: 'influId',
      model: 'influencer',
      select: { '_id': 1,'user':1},
      populate: {
        path: 'userid',
        model: 'User'
      }
   })
 .populate('campaignId',{'campaignTitle':1})
 .exec(callback);
}

There is something called 'locked reference' in excel which you can use for this, and you use $ symbols to lock a range. For your example, you would use:

=IF(B4<>"",B4/B$1,"")

This locks the 1 in B1 so that when you copy it to rows below, 1 will remain the same.

If you use $B$1, the range will not change when you copy it down a row or across a column.

The best version is certainly to use the builtin way:

string Tabs(int len) { return new string('\t', len); }

Of the other solutions, prefer the easiest; only if this is proving too slow, strive for a more efficient solution.

If you use a StringBuilder and know its resulting length in advance, then also use an appropriate constructor, this is much more efficient because it means that only one time-consuming allocation takes place, and no unnecessary copying of data. Nonsense: of course the above code is more efficient.

Try this:

<script type="text/javascript">
$.fn.toggleFuncs = function() {
    var functions = Array.prototype.slice.call(arguments),
    _this = this.click(function(){
        var i = _this.data('func_count') || 0;
        functions[i%functions.length]();
        _this.data('func_count', i+1);
    });
}
$('$showmenu').toggleFuncs(
        function() {
           $( ".menu" ).toggle( "drop" );
            },
            function() {
                $( ".menu" ).toggle( "drop" );
            }
); 

</script>

First fuction is an alternative to JQuery deprecated toggle :) . Works good with JQuery 2.0.3 and JQuery UI 1.10.3

Type Conversions T() where T is the desired datatype of the result are quite simple in GoLang.

In my program, I scan an integer i from the user input, perform a type conversion on it and store it in the variable f. The output prints the float64 equivalent of the int input. float32 datatype is also available in GoLang

Code:

package main
import "fmt"
func main() {
    var i int
    fmt.Println("Enter an Integer input: ")
    fmt.Scanf("%d", &i)
    f := float64(i)
    fmt.Printf("The float64 representation of %d is %f\n", i, f)
}

Solution:

>>> Enter an Integer input:
>>> 232332
>>> The float64 representation of 232332 is 232332.000000

Can you get away with recreating the staging table from scratch every time the query is executed? If so you could use SELECT ... INTO syntax and let SQL Server worry about creating the table using the correct column types etc.

SELECT *
INTO your_staging_table
FROM enormous_collection_of_views_tables_etc

I always liked using date -r /the/file +%s to find its age.

You can also do touch --date '2015-10-10 9:55' /tmp/file to get extremely fine-grained time on an arbitrary date/time.

ld is trying to find libcrypto.sowhich is not present as seen in your locate output. You can make a copy of the libcrypto.so.0.9.8 and name it as libcrypto.so. Put this is your ld path. ( If you do not have root access then you can put it in a local path and specify the path manually )

I've made a short code to do that and I want to share it with you.

Here the main code:

public void Send(string from, string password, string to, string Message, string subject, string host, int port, string file)
{

  MailMessage email = new MailMessage();
  email.From = new MailAddress(from);
  email.To.Add(to);
  email.Subject = subject;
  email.Body = Message;
  SmtpClient smtp = new SmtpClient(host, port);
  smtp.UseDefaultCredentials = false;
  NetworkCredential nc = new NetworkCredential(from, password);
  smtp.Credentials = nc;
  smtp.EnableSsl = true;
  email.IsBodyHtml = true;
  email.Priority = MailPriority.Normal;
  email.BodyEncoding = Encoding.UTF8;

  if (file.Length > 0)
  {
    Attachment attachment;
    attachment = new Attachment(file);
    email.Attachments.Add(attachment);
  }

  // smtp.Send(email);
  smtp.SendCompleted += new SendCompletedEventHandler(SendCompletedCallBack);
  string userstate = "sending ...";
  smtp.SendAsync(email, userstate);
}

private static void SendCompletedCallBack(object sender,AsyncCompletedEventArgs e) {
  string result = "";
  if (e.Cancelled)
  {    
    MessageBox.Show(string.Format("{0} send canceled.", e.UserState),"Message",MessageBoxButtons.OK,MessageBoxIcon.Information);
  }
  else if (e.Error != null)
  {
    MessageBox.Show(string.Format("{0} {1}", e.UserState, e.Error), "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
  }
  else {
    MessageBox.Show("your message is sended", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information);
  }

}

In your button do stuff like this
you can add your jpg or pdf files and more .. this is just an example

using (OpenFileDialog attachement = new OpenFileDialog()
{
  Filter = "Exel Client|*.png",
  ValidateNames = true
})
{
if (attachement.ShowDialog() == DialogResult.OK)
{
  Send("[email protected]", "gmail_password", 
       "[email protected]", "just smile ", "mail with attachement",
       "smtp.gmail.com", 587, attachement.FileName);

}
}

I wrote a class specifically for doing this. It's initialized with a "base" part (defaults to a minute-accurate timestamp) and after that appends letters to make unique names. So, if the first stamp generated is 1907101215a, the second would be 1907101215b, then 1907101215c, et cetera.

If I need more than 25 unique stamps then I use unary 'z's to count 25's. So, it goes 1907101215y, 1907101215za, 1907101215zb, ... 1907101215zy, 1907101215zza, 1907101215zzb, and so forth. This guarantees that the stamps will always sort alphanumerically in the order they were generated (as long as the next character after the stamp isn't a letter).

It isn't thread-safe, doesn't automatically update the time, and quickly bloats if you need hundreds of stamps, but I find it sufficient for my needs.

sys.tables

Contains all tables. so exec this query to get all tables with details.

SELECT * FROM sys.tables

or simply select Name from sys.tables to get the name of all tables.

SELECT Name From sys.tables

Swift 4 Update

I also tried many options still i wasn't able to get my UIButton round cornered. I added the corner radius code inside the viewDidLayoutSubviews() Solved My issue.

func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        anyButton.layer.cornerRadius = anyButton.frame.height / 2
    }

Also we can adjust the cornerRadius as follows

func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        anyButton.layer.cornerRadius = 10 //Any suitable number as you prefer can be applied 
    }

Surprised that I did not see the below query selector way solution,

document.querySelector('#xyz').style.paddingTop = "10px"

CSSStyleDeclaration solutions, an example of the accepted answer

document.getElementById('xyz').style.paddingTop = "10px";

File extensions do not have any bearing or impact on the content of the file. You can hold YAML content in files with any extension: .yml, .yaml or indeed anything else.

The (rather sparse) YAML FAQ recommends that you use .yaml in preference to .yml, but for historic reasons many Windows programmers are still scared of using extensions with more than three characters and so opt to use .yml instead.

So, what really matters is what is inside the file, rather than what its extension is.

if you want to only search with attribute name with any value

from bs4 import BeautifulSoup
import re

soup= BeautifulSoup(html.text,'lxml')
results = soup.findAll("td", {"valign" : re.compile(r".*")})

as per Steve Lorimer better to pass True instead of regex

results = soup.findAll("td", {"valign" : True})

string nonNormalized = "\r\n\n\r";

string normalized = nonNormalized.Replace("\r", "\n").Replace("\n", "\r\n");

You can make your own BinaryTree data structure in Python the OOP way (or building a class). You can separate two class in here: Node and BinaryTree. The "Node" class will be responsible for creating individual node objects for the BinaryTree while the "BinaryTree" class is what you'll need to implement the binary tree on top of the "Node" class.

Here's what I coded when I'm studying it back then:

class TreeNode:

    def __init__(self, data=None):
        self.data = data
        self.left = None
        self.right = None

    def __str__(self):
        return f'Node(Data={self.data}, Left={self.left}, Right={self.right})'

    def __repr__(self):
        return self.__str__()

    def get_data(self):
        return self.data

    def set_data(self, data):
        self.data = data

    def get_left(self):
        return self.left

    def set_left(self, left):
        self.left = left

    def get_right(self):
        return self.right

    def set_right(self, right):
        self.right = right

class BinaryTree:

    def __init__(self, root=None):
        self.root = TreeNode(root)

    def __str__(self):
        return f'BinaryTree({self.root})'

    def __repr__(self):
        return f'BinaryTree({self.root})'

    def insert(self, data):
        # if empty tree
        if self.root.get_data() is None:
            return self.root.set_data(data)
        new_node = TreeNode(data)
        current = self.root
        while True:
            if data < current.get_data():
                if current.get_left() is None:
                    return current.set_left(new_node)
                current = current.get_left()
                continue
            elif data > current.get_data():
                if current.get_right() is None:
                    return current.set_right(new_node)
                current = current.get_right()
                continue
            return

    # still needs other methods like the delete method, but you can
    # try it out yourself
    def delete(self, node):
        pass

def main():
    myTree = BinaryTree()
    myTree.insert(5)
    myTree.insert(3)
    myTree.insert(4)
    myTree.insert(2)
    myTree.insert(8)
    myTree.insert(9)
    myTree.insert(6)
    print(myTree)

if __name__ == '__main__':
    main()

You need to use the border property as seen here: jsFiddle

HTML:

<table width="770">
    <tr>
        <td class="border-left-bottom">picture (border only to the left and bottom ) </td>
        <td>text</td>
    </tr>
    <tr>
        <td>text</td>
        <td class="border-left-bottom">picture (border only to the left and bottom) </td>
    </tr>
</table>`

CSS:

td.border-left-bottom{
    border-left: solid 1px #000;
    border-bottom: solid 1px #000;
}

Worked great on CentOS 6.5

yum install bcmath

All my calls to bcmath functions started working right after an apache restart

service httpd restart

Sweet!

Because you didn't tell the linker about location of math library. Compile with gcc test.c -o test -lm

I had the same problem. I had used

git format-patch <commit_hash>

to create the patch. My main problem was patch was failing due to some conflicts, but I could not see any merge conflict in the file content. I had used git am --3way <patch_file_path> to apply the patch.

The correct command to apply the patch should be:

git am --3way --ignore-space-change <patch_file_path>

If you execute the above command for patching, it will create a merge conflict if patch apply fails. Then you can fix the conflict in your files, like the same way merge conflicts are resolved for git merge

In order to open a link in a new tab/window you'll use <a target="_blank">.

value _blank = targeted browsing context: a new one: tab or window depending on your browsing settings

value _new = not valid; no such value in HTML5 for target attribute on a element

target attribute with all its values on a element: video demo

I'm a bit late to the party here but here's the simplest solution I know for the old AdSense code with jQuery:

$ads = $("ins");
if ($ads.length == 0) {
    // Replacement code about you needing ad income
}

And in plain JavaScript:

$ads = document.getElementsByTagName("ins");
if ($ads.length == 0) {
    // Replacement code about you needing ad income
}

For $ads you can use any selector that you know is consistent with the ad being generated. E.g. for the new AdSense code you can use $("iframe#google_ads_frame1").

RPC is an old protocol based on C.It can invoke a remote procedure and make it look like a local call.RPC handles the complexities of passing that remote invocation to the server and getting the result to client.

Java RMI also achieves the same thing but slightly differently.It uses references to remote objects.So, what it does is that it sends a reference to the remote object alongwith the name of the method to invoke.It is better because it results in cleaner code in case of large programs and also distribution of objects over the network enables multiple clients to invoke methods in the server instead of establishing each connection individually.

 >>> a = {'foo': 'bar', 'baz': 'quux', 'hello': 'world'}
 >>> list(reduce(lambda x, y: x + y, a.items()))
 ['foo', 'bar', 'baz', 'quux', 'hello', 'world']

To explain: a.items() returns a list of tuples. Adding two tuples together makes one tuple containing all elements. Thus the reduction creates one tuple containing all keys and values and then the list(...) makes a list from that.

For Ansible 2.x:

- name: template test
  template: 
    src: myTemplateFile
    dest: result1
  vars:
    myTemplateVariable: File1

- name: template test
  template: 
    src: myTemplateFile
    dest: result2
  vars:
    myTemplateVariable: File2

For Ansible 1.x:

Unfortunately the template module does not support passing variables to it, which can be used inside the template. There was a feature request but it was rejected.

I can think of two workarounds:

1. Include

The include statement supports passing variables. So you could have your template task inside an extra file and include it twice with appropriate parameters:

my_include.yml:

- name: template test
  template: 
        src=myTemplateFile
        dest=destination

main.yml:

- include: my_include.yml destination=result1 myTemplateVariable=File1

- include: my_include.yml destination=result2 myTemplateVariable=File2

2. Re-define myTemplateVariable

Another way would be to simply re-define myTemplateVariable right before every template task.

- set_fact:
     myTemplateVariable: File1

- name: template test 1
  template: 
        src=myTemplateFile
        dest=result1

- set_fact:
     myTemplateVariable: File2

- name: template test 2
  template: 
        src=myTemplateFile
        dest=result2

MVVM Model-View ViewModel is similar to MVC, Model-View Controller

The controller is replaced with a ViewModel. The ViewModel sits below the UI layer. The ViewModel exposes the data and command objects that the view needs. You could think of this as a container object that view goes to get its data and actions from. The ViewModel pulls its data from the model.

Russel East does a blog discussing more in detail Why is MVVM is different from MVC

The context object allows you to manipulate the canvas; you can draw rectangles for example and a lot more.

If you want to get the width and height, you can just use the standard HTML attributes width and height:

var canvas = document.getElementById( 'yourCanvasID' );
var ctx = canvas.getContext( '2d' );

alert( canvas.width );
alert( canvas.height ); 

I totally agree with both the question and Martin's answer :). Even in Java, reading javadoc with generics is much harder than it should be due to the extra noise. This is compounded in Scala where implicit parameters are used as in the questions's example code (while the implicits do very useful collection-morphing stuff).

I don't think its a problem with the language per se - I think its more a tooling issue. And while I agree with what Jörg W Mittag says, I think looking at scaladoc (or the documentation of a type in your IDE) - it should require as little brain power as possible to grok what a method is, what it takes and returns. There shouldn't be a need to hack up a bit of algebra on a bit of paper to get it :)

For sure IDEs need a nice way to show all the methods for any variable/expression/type (which as with Martin's example can have all the generics inlined so its nice and easy to grok). I like Martin's idea of hiding the implicits by default too.

To take the example in scaladoc...

def map[B, That](f: A => B)(implicit bf: CanBuildFrom[Repr, B, That]): That

When looking at this in scaladoc I'd like the generic block [B, That] to be hidden by default as well as the implicit parameter (maybe they show if you hover a little icon with the mouse) - as its extra stuff to grok reading it which usually isn't that relevant. e.g. imagine if this looked like...

def map(f: A => B): That

nice and clear and obvious what it does. You might wonder what 'That' is, if you mouse over or click it it could expand the [B, That] text highlighting the 'That' for example.

Maybe a little icon could be used for the [] declaration and (implicit...) block so its clear there are little bits of the statement collapsed? Its hard to use a token for it, but I'll use a . for now...

def map.(f: A => B).: That

So by default the 'noise' of the type system is hidden from the main 80% of what folks need to look at - the method name, its parameter types and its return type in nice simple concise way - with little expandable links to the detail if you really care that much.

Mostly folks are reading scaladoc to find out what methods they can call on a type and what parameters they can pass. We're kinda overloading users with way too much detail right how IMHO.

Here's another example...

def orElse[A1 <: A, B1 >: B](that: PartialFunction[A1, B1]): PartialFunction[A1, B1]

Now if we hid the generics declaration its easier to read

def orElse(that: PartialFunction[A1, B1]): PartialFunction[A1, B1]

Then if folks hover over, say, A1 we could show the declaration of A1 being A1 <: A. Covariant and contravariant types in generics add lots of noise too which can be rendered in a much easier to grok way to users I think.

I encountered the same problem, but I check find that I hadn't the parent table. So I just edit the parent migration in front of the child migration. Just do it.

You can try this script out since you do not want to target the Xoom only. I don't have a Xoom, but should work.

function mobile_detect(mobile,tablet,mobile_redirect,tablet_redirect,debug) {
var ismobile = (/iphone|ipod|android|blackberry|opera|mini|windows\sce|palm|smartphone|iemobile/i.test(navigator.userAgent.toLowerCase()));
var istablet = (/ipad|android|android 3.0|xoom|sch-i800|playbook|tablet|kindle/i.test(navigator.userAgent.toLowerCase()));

if (debug == true) {
    alert(navigator.userAgent);
}

if (ismobile && mobile==true) {
    if (debug == true) {
        alert("Mobile Browser");
    }
    window.location = mobile_redirect;
} else if (istablet && tablet==true) {
    if (debug == true) {
        alert("Tablet Browser");
    }
    window.location = tablet_redirect;
}
}

I created a project on github. Check it out - https://github.com/codefuze/js-mobile-tablet-redirect. Feel free to submit issues if there is anything wrong!

Better still (or shorter anyway):

SUM(ccc_news_comments.id = 'approved')

This works since the Boolean type in MySQL is represented as INT 0 and 1, just like in C. (May not be portable across DB systems though.)

As for COALESCE() as mentioned in other answers, many language APIs automatically convert NULL to '' when fetching the value. For example with PHP's mysqli interface it would be safe to run your query without COALESCE().

It will be created once you close the file (with or without writing). Use os.path.join() to create your path eg

filepath = os.path.join("c:\\","test.py")

You don't show the code for display_data, but here's what you need to do:

print "$%0.02f" %amount

This is a format specifier for the variable amount.

Since this is beginner topic, I won't get into floating point rounding error, but it's good to be aware that it exists.

Update August 2019

In Android Studio 3.5 Instant Run was replaced with Apply Changes. And it works in different way: APK is not modified on the fly anymore but instead runtime instrumentation is used to redefine classes on the fly (more info). So since Android Studio 3.5 instant run settings are replaced with Deployment (Settings -> Build, Execution, Deployment -> Deployment):

You don't need initialization lists for that:

std::vector<int> vector1(length, 0);
std::vector<double> vector2(length, 0.0);

You can use Google Translate API v2 Java. It has a core module that you can call from your Java code and also a command line interface module.

You are using an inline table value function. Therefore you must use Select * From function. If you want to use select function() you must use a scalar function.

Update from 09/2017

It is possible to develop iOS (and Android at the same time) application using React Native + Expo without owning a mac. You will also be able to run your iOS application within iOS Expo app while developing it. (You can even publish it for other people to access, but it will only run within Expo app). Here is page from Expo on how to generate standalone app.

Steps from that page:

One: Install exp by running npm install -g exp

Two: Configure app.json (somewhere along these lines):

{
   "expo": {
    "name": "Your App Name",
    "icon": "./path/to/your/app-icon.png",
    "version": "1.0.0",
    "slug": "your-app-slug",
    "sdkVersion": "17.0.0",
    "ios": {
      "bundleIdentifier": "com.yourcompany.yourappname"
    },
    "android": {
      "package": "com.yourcompany.yourappname"
    }
   }
 }

Three: Start exp packeger with exp start

Four: run exp build:android or exp build:ios.

You will be prompted for some input. For android you can choose 1) Let Expo handle the process! if you don't have keystore (or if you don't know what it is). For iOS you will have to enter your Apple developer credentials. Then you can provide distribution certificate or let expo handle it.

Five: Once in a while you will have to come back and run exp build:status command to check whether your build was complete. If complete you will be provided a direct link to .apk or .ipa file.

The only drawback to this approach is that it won't be as native as writing iOS app in Swift, and you will have to put up with parade of issues you may run into while developing with weakly typed js, npm, and it's dependency-on-particular-version-of-some-other-library issues, and other stuff.

If you need to find values for variables other than those standard VS macros, you could do that easily using Process Explorer. Start it, find the process your Visual Studio instance runs in, right click, Properties ? Environment. It lists all those $ vars as key-value pairs:

Although this post is post is tagged for Windows, it is relevant question on OS X that I have not seen answers for elsewhere. Here are steps to create a self-signed cert for localhost on OS X:

# Use 'localhost' for the 'Common name'
openssl req -x509 -sha256 -nodes -newkey rsa:2048 -days 365 -keyout localhost.key -out localhost.crt

# Add the cert to your keychain
open localhost.crt

In Keychain Access, double-click on this new localhost cert. Expand the arrow next to "Trust" and choose to "Always trust". Chrome and Safari should now trust this cert. For example, if you want to use this cert with node.js:

var options = {
    key: fs.readFileSync('/path/to/localhost.key').toString(),
    cert: fs.readFileSync('/path/to/localhost.crt').toString(),
    ciphers: 'ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES256-SHA384',
    honorCipherOrder: true,
    secureProtocol: 'TLSv1_2_method'
};

var server = require('https').createServer(options, app);

I encountered this issue, but in my case the password for the 'phpmyadmin' user did not match the contents of /etc/phpmyadmin/config-db.php

Once I updated the password for the 'phpmyadmin' user the error went away.

These are the steps I took:

1. Log in to mysql as root: mysql -uroot -pYOUR_ROOT_PASS
2. Change to the 'mysql' db: use mysql;
3. Update the password for the 'phpmyadmin' user: UPDATE mysql.user SET Password=PASSWORD('YOUR_PASS_HERE') WHERE User='phpmyadmin' AND Host='localhost';
4. Flush privileges: FLUSH PRIVILEGES;

DONE!! It worked for me.

It's enough to do:

data=`date`
datatime=`date -d "${data}" '+%Y%m%d'`
echo $datatime
20190206

If you want to add also the time you can use in that way

data=`date`
datatime=`date -d "${data}" '+%Y%m%d %T'`

echo $data
Wed Feb 6 03:57:15 EST 2019

echo $datatime
20190206 03:57:15

This post itself is not a direct answer to the question. What it is instead is a data-driven extensible benchmark that can be used to compare many of the answers (and variations of utilizing new features added in later, more modern, versions of Python) that have been posted to this question — and should therefore be helpful in determining which has the best performance.

In a few cases I've modified the code in the referenced answer to make it compatible with the benchmark framework.

Canvas would be a great way to do this, as @pst said above. Check out this answer for a good example:

getPixel from HTML Canvas?

Some code that would serve you specifically as well:

var imgd = context.getImageData(x, y, width, height);
var pix = imgd.data;

for (var i = 0, n = pix.length; i < n; i += 4) {
  console.log pix[i+3]
}

This will go row by row, so you'd need to convert that into an x,y and either convert the for loop to a direct check or run a conditional inside.

Reading your question again, it looks like you want to be able to get the point that the person clicks on. This can be done pretty easily with jquery's click event. Just run the above code inside a click handler as such:

$('el').click(function(e){
   console.log(e.clientX, e.clientY)
}

Those should grab your x and y values.

It should be on Project -> app folder

Please find the screenshot from Firebase website

The best way that I've found to revert a min-width setting is:

min-width: 0;
min-width: unset;

unset is in the spec, but some browsers (IE 10) do not respect it, so 0 is a good fallback in most cases. min-width: 0;

Close chrome (or chromium) and restart with the --disable-web-security argument. I just tested this and verified that I can access the contents of an iframe with src="http://google.com" embedded in a page served from "localhost" (tested under chromium 5 / ubuntu). For me the exact command was:

Note : Kill all chrome instances before running command

chromium-browser --disable-web-security --user-data-dir="[some directory here]"

The browser will warn you that "you are using an unsupported command line" when it first opens, which you can ignore.

From the chromium source:

// Don't enforce the same-origin policy. (Used by people testing their sites.)
const wchar_t kDisableWebSecurity[] = L"disable-web-security";

Before Chrome 48, you could just use:

chromium-browser --disable-web-security

Yes. add a linked server entry, and use select into using the four part db object naming convention.

Example:

SELECT * INTO targetTable 
FROM [sourceserver].[sourcedatabase].[dbo].[sourceTable]

No-one has mentioned the map function, which allows a function to operate element-wise on a list:

mydictionary = {'a': 'apple', 'b': 'bear', 'c': 'castle'}
keys = ['b', 'c']

values = list( map(mydictionary.get, keys) )

# values = ['bear', 'castle']

My problem was creating the route first require("./routes/routes")(app); I shifted it to the end of the code before app.listen and it worked!

Probably you need to set library reference as "Copy Local = True" on properties dialog. On visual studio click on "references" then right-click on the missing reference, from the context menu click properties, you should see copy local setting.

I changed Scanner fin = new Scanner(file); to Scanner fin = new Scanner(new File(file)); and it works perfectly now. I didn't think the difference mattered but there you go.

SELECT r.conname
      ,ct.table_name
      ,pg_catalog.pg_get_constraintdef(r.oid, true) as condef
  FROM pg_catalog.pg_constraint r, information_schema.constraint_table_usage ct
 WHERE r.contype = 'f' 
   AND r.conname = ct.constraint_name
 ORDER BY 1

 SELECT * FROM table ORDER BY RAND() LIMIT 1

The closest thing would be the bind function:

http://api.jquery.com/bind/

$('#foo').bind('click', function() {
  alert('User clicked on "foo."');
});

Here is what I use to convert to the XSD datetime format:

from datetime import datetime
datetime.now().replace(microsecond=0).isoformat()
# You get your ISO string

I came across this question when looking for the XSD date time format (xs:dateTime). I needed to remove the microseconds from isoformat.

Try this,

<?php
$arr1=array('result1'=>'abcd','result2'=>'efg'); 
$arr2=array('result1'=>'hijk','result2'=>'lmn'); 
$arr3=array($arr1,$arr2); 
print (json_encode($arr3)); 
?>

The following works without flattening the folder structure:

gulp.src(['input/folder/**/*']).pipe(gulp.dest('output/folder'));

The '**/*' is the important part. That expression is a glob which is a powerful file selection tool. For example, for copying only .js files use: 'input/folder/**/*.js'

To long from DateTime:

long DateTime.Ticks

To DateTime from long:

new DateTime(long)

You can use chmod with the X mode letter (the capital X) to set the executable flag only for directories.

In the example below the executable flag is cleared and then set for all directories recursively:

~$ mkdir foo
~$ mkdir foo/bar
~$ mkdir foo/baz
~$ touch foo/x
~$ touch foo/y

~$ chmod -R go-X foo 
~$ ls -l foo
total 8
drwxrw-r-- 2 wq wq 4096 Nov 14 15:31 bar
drwxrw-r-- 2 wq wq 4096 Nov 14 15:31 baz
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 x
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 y

~$ chmod -R go+X foo 
~$ ls -l foo
total 8
drwxrwxr-x 2 wq wq 4096 Nov 14 15:31 bar
drwxrwxr-x 2 wq wq 4096 Nov 14 15:31 baz
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 x
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 y

A bit of explaination:

• chmod -x foo - clear the eXecutable flag for foo
• chmod +x foo - set the eXecutable flag for foo
• chmod go+x foo - same as above, but set the flag only for Group and Other users, don't touch the User (owner) permission
• chmod go+X foo - same as above, but apply only to directories, don't touch files
• chmod -R go+X foo - same as above, but do this Recursively for all subdirectories of foo

Whilst I was looking for my answer for the same question, I found this:

<img src="img.png" style=max-
width:100%;overflow:hidden;border:none;padding:0;margin:0 auto;display:block;" marginheight="0" marginwidth="0">

You can use it inside a tag (iframe or img) the image will adjust based on it's device.

A better way would be to use Stopwatch, instead of DateTime differences.

Stopwatch Class - Microsoft Docs

Provides a set of methods and properties that you can use to accurately measure elapsed time.

Stopwatch stopwatch = Stopwatch.StartNew(); //creates and start the instance of Stopwatch
//your sample code
System.Threading.Thread.Sleep(500);
stopwatch.Stop();
Console.WriteLine(stopwatch.ElapsedMilliseconds);

Triggering browser download from front-end is not reliable.

What you should do is, create an endpoint that when called, will provide the correct response headers, thus triggering the browser download.

Front-end code can only do so much. The 'download' attribute for example, might just open the file in a new tab depending on the browser.

The response headers you need to look at are probably Content-Type and Content-Disposition. You should check this answer for more detailed explanation.

On each entry in textbox (event - Handles RestrictedTextBox.TextChanged), you can do a try to caste entered text into integer, if failure occurs, you just reset the value of the text in RestrictedTextBox to last valid entry (which gets constantly updating under the temp1 variable).

Here's how to go about it. In the sub that loads with the form (me.load or mybase.load), initialize temp1 to the default value of RestrictedTextBox.Text

Dim temp1 As Integer 'initialize temp1 default value, you should do this after the default value for RestrictedTextBox.Text was loaded.
If (RestrictedTextBox.Text = Nothing) Then 
    temp1 = Nothing
Else
    Try 
        temp1 = CInt(RestrictedTextBox.Text)
    Catch ex As Exception
        temp1 = Nothing
    End Try
End If   

At any other point in form:

Private Sub textBox_TextChanged(sender As System.Object, e As System.EventArgs) Handles RestrictedTextBox.TextChanged
    Try
        temp1 = CInt(RestrictedTextBox.Text) 'If user inputs integer, this will succeed and temp will be updated
    Catch ex As Exception
        RestrictedTextBox.Text = temp1.ToString 'If user inputs non integer, textbox will be reverted to state the state it was in before the string entry
    End Try
End Sub

The nice thing about this is that you can use this to restrict a textbox to any type you want: double, uint etc....

I have done with easy way:

Hope this will help you.

Update: there are two possible scenarios here:

1. You are determining if an object is a collection;

2. You are determining if a class is a collection.

The solutions are slightly different but the principles are the same. You also need to define what exactly constitutes a "collection". Implementing either Collection or Map will cover the Java Collections.

Solution 1:

public static boolean isCollection(Object ob) {
  return ob instanceof Collection || ob instanceof Map;
}

Solution 2:

public static boolean isClassCollection(Class c) {
  return Collection.class.isAssignableFrom(c) || Map.class.isAssignableFrom(c);
}

(1) can also be implemented in terms of (2):

public static boolean isCollection(Object ob) {
  return ob != null && isClassCollection(ob.getClass());
}

I don't think the efficiency of either method will be greatly different from the other.

To define the file to import it's possible to use all folders common definitions. You just have to be aware that it's relative to file you are defining it. More about import option with examples you can check here.

You can call pack_forget to remove a widget (if you use pack to add it to the window).

Example:

from tkinter import *

root = Tk()

b = Button(root, text="Delete me", command=lambda: b.pack_forget())
b.pack()

root.mainloop()

If you use pack_forget, you can later show the widget again calling pack again. If you want to permanently delete it, call destroy on the widget (then you won't be able to re-add it).

If you use the grid method, you can use grid_forget or grid_remove to hide the widget.

Here's some sample code. This worked for me.

<LinearLayout
    android:gravity="center"
    >
    <TextView
        android:layout_gravity="center"
        />
    <Button
        android:layout_gravity="center"
        />
</LinearLayout>

So you're designing the Linear Layout to place all its contents (TextView and Button) in its center, and then the TextView and Button are placed relative to the center of the Linear Layout.

Another way to navigate to the location of a function definition would be to break in debugger somewhere you can access the function and enter the functions fully qualified name in the console. This will print the function definition in the console and give a link which on click opens the script location where the function is defined.

I think Nathan Long's answer is the way to go. For me, I am using client-side validation, so I just added a condition that the form be valid.

EDIT: If this is not added, the user will never be able to submit the form if the client-side validation encounters an error.

        // jQuery plugin to prevent double submission of forms
        jQuery.fn.preventDoubleSubmission = function () {
            $(this).on('submit', function (e) {
                var $form = $(this);

                if ($form.data('submitted') === true) {
                    // Previously submitted - don't submit again
                    alert('Form already submitted. Please wait.');
                    e.preventDefault();
                } else {
                    // Mark it so that the next submit can be ignored
                    // ADDED requirement that form be valid
                    if($form.valid()) {
                        $form.data('submitted', true);
                    }
                }
            });

            // Keep chainability
            return this;

Did you check the gsl package in your system. Try with this:

ldconfig-p | grep gsl

If gsl is installed, it will display the configuration path. If it is not in the standard path /usr/lib/ then you need to do the following in bash:

export PATH=$PATH:/your/path/to/gsl-config 

If gsl is not installed, simply do

sudo apt-get install libgsl0ldbl
sudo apt-get install gsl-bin libgsl0-dev

I had a problem with the mvabund package and this fixed the error

Cheers!

I know this may be a bit old, but try using PDO::lastInsertId. I think it does what you want it to, but you would have to rewrite your application to use PDO (Which is a lot safer against attacks)

Online PHP lint

PHPLint

Unitialized variables check. Link 1 and 2 already seem to do this just fine, though.

I can't say I have used any of these intensively, though :)

In my case I made the mistake of copying *ng-for= from the docs.

https://angular.io/guide/user-input

Correct me if I am wrong. But it seems *ng-for= has been changed to *ngFor=

Use CHAR:

=Char(34)&"This is in quotes"&Char(34)

Should evaluate to:

"This is in quotes"

1. Copy the contents of the file,
2. Create an .h file, give it the name of the original .h file
3. Copy the contents of the original file to the newly created one
4. Build it
5. VOILA!!

But I get an error "! [rejected]" and something about "non fast forward"

That's because Git can't merge the changes from the branches into your current master. Let's say you've checked out branch master, and you want to merge in the remote branch other-branch. When you do this:

$ git pull origin other-branch

Git is basically doing this:

$ git fetch origin other-branch && git merge other-branch

That is, a pull is just a fetch followed by a merge. However, when pull-ing, Git will only merge other-branch if it can perform a fast-forward merge. A fast-forward merge is a merge in which the head of the branch you are trying to merge into is a direct descendent of the head of the branch you want to merge. For example, if you have this history tree, then merging other-branch would result in a fast-forward merge:

O-O-O-O-O-O
^         ^
master    other-branch

However, this would not be a fast-forward merge:

    v master
O-O-O
\
 \-O-O-O-O
         ^ other-branch

To solve your problem, first fetch the remote branch:

$ git fetch origin other-branch

Then merge it into your current branch (I'll assume that's master), and fix any merge conflicts:

$ git merge origin/other-branch
# Fix merge conflicts, if they occur
# Add merge conflict fixes
$ git commit    # And commit the merge!

Simplest solution is probably to use tr

$ cat -A input
^I    Name, ^IOrder  $
  Trim, working  $
cat,cat1^I  

$ tr -d '[:blank:]' < input | cat -A
Name,Order$
Trim,working$
cat,cat1

Simple:

    dim input as string = "SPQR"
    dim format as string =""
    dim result as string = ""

    'pad left:
    format = "{0,-8}"
    result = String.Format(format,input)
    'result = "SPQR    "

    'pad right
    format = "{0,8}"
    result = String.Format(format,input)
    'result = "    SPQR"

FIX 1:

Step1: Go to settings > then select the following configuration(Disable Floppy)

Alternatively, you can press F12 while booting the Guest OS and select CD from there, this is a one time setting, good enough for the installation.

Step 2: Place your Existing Guest OS bootable CD in the Disk Drive and start the Guest OS.

FIX 2:

Go to Settings > And Perform the following:

FIX 3:

Try Fix 1 & 2 together..

Correct final syntax for [Mr. C]s answer.

With the release of VS2017RC and its C#7 support it works this way:

switch(message)
{
    case string a when a.Contains("test2"): return "no";
    case string b when b.Contains("test"): return "yes";
}

You should take care of the case ordering as the first match will be picked. That's why "test2" is placed prior to test.

use utf8; does not enable Unicode output - it enables you to type Unicode in your program. Add this to the program, before your print() statement:

binmode(STDOUT, ":utf8");

See if that helps. That should make STDOUT output in UTF-8 instead of ordinary ASCII.

I'm assuming you have fromPath (an absolute path for a folder), and toPath (an absolute path for a folder/file), and your're looking for a path that with represent the file/folder in toPath as a relative path from fromPath (your current working directory is fromPath) then something like this should work:

public static String getRelativePath(String fromPath, String toPath) {

  // This weirdness is because a separator of '/' messes with String.split()
  String regexCharacter = File.separator;
  if (File.separatorChar == '\\') {
    regexCharacter = "\\\\";
  }

  String[] fromSplit = fromPath.split(regexCharacter);
  String[] toSplit = toPath.split(regexCharacter);

  // Find the common path
  int common = 0;
  while (fromSplit[common].equals(toSplit[common])) {
    common++;
  }

  StringBuffer result = new StringBuffer(".");

  // Work your way up the FROM path to common ground
  for (int i = common; i < fromSplit.length; i++) {
    result.append(File.separatorChar).append("..");
  }

  // Work your way down the TO path
  for (int i = common; i < toSplit.length; i++) {
    result.append(File.separatorChar).append(toSplit[i]);
  }

  return result.toString();
}

Perhaps you could turn some of the arguments into member variables. If you need that much state a class sounds like a good idea to me.

Try adding in log4j.xml

<!--  enable query logging -->
<category name="org.springframework.jdbc.core.JdbcTemplate">
    <priority value="DEBUG" />
</category>

<!-- enable query logging for SQL statement parameter value -->
<category name="org.springframework.jdbc.core.StatementCreatorUtils">
    <priority value="TRACE" />
</category>

your logs looks like:

DEBUG JdbcTemplate:682 - Executing prepared SQL query
DEBUG JdbcTemplate:616 - Executing prepared SQL statement [your sql query]
TRACE StatementCreatorUtils:228 - Setting SQL statement parameter value: column index 1, parameter value [param], value class [java.lang.String], SQL type unknown

The Gist I found and works for me:

const DummyLink = ({onClick, children, props}) => (
    <a href="#" onClick={evt => {
        evt.preventDefault();
        onClick && onClick();
    }} {...props}>
        {children}
    </a>
);

Delaying showing the route is sure to lead to an asynchronous tangle... why not simply track the loading status of your main entity and use that in the view. For example in your controller you might use both the success and error callbacks on ngResource:

$scope.httpStatus = 0; // in progress
$scope.projects = $resource.query('/projects', function() {
    $scope.httpStatus = 200;
  }, function(response) {
    $scope.httpStatus = response.status;
  });

Then in the view you could do whatever:

<div ng-show="httpStatus == 0">
    Loading
</div>
<div ng-show="httpStatus == 200">
    Real stuff
    <div ng-repeat="project in projects">
         ...
    </div>
</div>
<div ng-show="httpStatus >= 400">
    Error, not found, etc. Could distinguish 4xx not found from 
    5xx server error even.
</div>

Note: this answer applies only to Angular components and directives, NOT services.

I had this same issue when ngOnInit (and other lifecycle hooks) were not firing for my components, and most searches led me here.

The issue is that I was using the arrow function syntax (=>) like this:

class MyComponent implements OnInit {
    // Bad: do not use arrow function
    public ngOnInit = () => {
        console.log("ngOnInit");
    }
}

Apparently that does not work in Angular 6. Using non-arrow function syntax fixes the issue:

class MyComponent implements OnInit {
    public ngOnInit() {
        console.log("ngOnInit");
    }
}

Here is a better way to loop over files as it handles spaces and newlines in file names:

#!/bin/bash

find . -type f -iname "*.txt" -print0 | while IFS= read -r -d $'\0' line; do
    echo "$line"
    ls -l "$line"    
done

Try onclick function separately it can give you access to execute your function which can be used to open up a new window, for this purpose you first need to create a javascript function there you can define it and in your anchor tag you just need to call your function.

Example:

function newwin() {              
 myWindow=window.open('lead_data.php?leadid=1','myWin','width=400,height=650')
}

See how to call it from your anchor tag

<a onclick='newwin()'>Anchor</a>

May be this will help you a lot to understand your problem.

The syntax for ng if else in angular is :

<div class="case" *ngIf="data.id === '5'; else elsepart; ">
    <input type="checkbox" id="{{data.id}}" value="{{data.displayName}}" 
    data-ng-model="customizationCntrl.check[data.id1]" data-ng-checked="
    {{data.status}}=='1'" onclick="return false;">{{data.displayName}}<br>
</div>
<ng-template #elsepart>
    <div class="case">
        <input type="checkbox" id="{{data.id}}" value={{data.displayName}}"  
        data-ng-model="customizationCntrl.check[data.id]" data-ng-checked="
        {{data.status}}=='1'">{{data.displayName}}<br>
    </div> 
</ng-template>
