You can use the Mock.call_args_list attribute to compare parameters to previous method calls. That in conjunction with Mock.call_count attribute should give you full control.

You have two ways:

Lets start by looking for a specific application in my laptop:

[root@pinky:~]# ps fax | grep mozilla
 3358 ?        S      0:00  \_ /bin/sh /usr/lib/firefox-3.5/run-mozilla.sh /usr/lib/firefox-3.5/firefox
16198 pts/2    S+     0:00              \_ grep mozilla

All examples now will look for PID 3358.

First way: Run "ps aux" and grep for the PID in the second column. In this example I look for firefox, and then for it's PID:

[root@pinky:~]# ps aux | awk '{print $2 }' | grep 3358
3358

So your code will be:

if [ ps aux | awk '{print $2 }' | grep -q $PID 2> /dev/null ]; then
    kill $PID 
fi

Second way: Just look for something in the /proc/$PID directory. I am using "exe" in this example, but you can use anything else.

[root@pinky:~]# ls -l /proc/3358/exe 
lrwxrwxrwx. 1 elcuco elcuco 0 2010-06-15 12:33 /proc/3358/exe -> /bin/bash

So your code will be:

if [ -f /proc/$PID/exe ]; then
    kill $PID 
fi

BTW: whats wrong with kill -9 $PID || true ?

EDIT:

After thinking about it for a few months.. (about 24...) the original idea I gave here is a nice hack, but highly unportable. While it teaches a few implementation details of Linux, it will fail to work on Mac, Solaris or *BSD. It may even fail on future Linux kernels. Please - use "ps" as described in other responses.

What "exactly" an API key is used for depends very much on who issues it, and what services it's being used for. By and large, however, an API key is the name given to some form of secret token which is submitted alongside web service (or similar) requests in order to identify the origin of the request. The key may be included in some digest of the request content to further verify the origin and to prevent tampering with the values.

Typically, if you can identify the source of a request positively, it acts as a form of authentication, which can lead to access control. For example, you can restrict access to certain API actions based on who's performing the request. For companies which make money from selling such services, it's also a way of tracking who's using the thing for billing purposes. Further still, by blocking a key, you can partially prevent abuse in the case of too-high request volumes.

In general, if you have both a public and a private API key, then it suggests that the keys are themselves a traditional public/private key pair used in some form of asymmetric cryptography, or related, digital signing. These are more secure techniques for positively identifying the source of a request, and additionally, for protecting the request's content from snooping (in addition to tampering).

The List interface already has this solved.

int temp = 2;
if(bankAccNos.contains(bakAccNo)) temp=1;

More can be found in the documentation about List.

Post Value from

Intent ii = new Intent(this, GameStartPage.class);

// ii.putExtra("pkgName", B2MAppsPKGName);

ii.putExtra("pkgName", YourValue);
ii.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(ii);

Get Value from

pkgn = getIntent().getExtras().getString("pkgName");

if you need the category ID, you would get it via get_query_var, that is capable of retrieving all publicly queryble variables.

$category_id = get_query_var('cat');

here is an example to get the category name

$category_name = get_query_var('category_name');

and of course the all mighty get_queried_object

$queried_object = get_queried_object();

that is returning the complete taxonomy term object (when used on a taxonomy-archive page..)

ISO-8859-1 is a legacy standards from back in 1980s. It can only represent 256 characters so only suitable for some languages in western world. Even for many supported languages, some characters are missing. If you create a text file in this encoding and try copy/paste some Chinese characters, you will see weird results. So in other words, don't use it. Unicode has taken over the world and UTF-8 is pretty much the standards these days unless you have some legacy reasons (like HTTP headers which needs to compatible with everything).

A Compiler translates lines of code from the programming language into machine language.

A Linker creates a link between two programs.

A Loader loads the program into memory in the main database, program, etc.

You can set sys.dont_write_bytecode = True in your source, but that would have to be in the first python file loaded. If you execute python somefile.py then you will not get somefile.pyc.

When you install a utility using setup.py and entry_points= you will have set sys.dont_write_bytecode in the startup script. So you cannot rely on the "default" startup script generated by setuptools.

If you start Python with python file as argument yourself you can specify -B:

python -B somefile.py

somefile.pyc would not be generated anyway, but no .pyc files for other files imported too.

If you have some utility myutil and you cannot change that, it will not pass -B to the python interpreter. Just start it by setting the environment variable PYTHONDONTWRITEBYTECODE:

PYTHONDONTWRITEBYTECODE=x myutil

if you don't care about original arrays and have no problem to edit them then this is quicker algorithm:

let iterator = arrayA.values()
let result = []
for (entryA of iterator) {
    if (!arrayB.includes(entryA)) {
        result.push(entryA)
    } else {
        arrayB.splice(arrayB.indexOf(entryA), 1) 
    }
}

result.push(...arrayB)
return result

If you are getting this error on Python 2.7 you can now get the Microsoft Visual C++ Compiler for Python 2.7 as a stand alone download.

If you are on 3.3 or later you need to install Visual Studio 2010 express which is available for free here: https://www.visualstudio.com/downloads/download-visual-studio-vs#d-2010-express

If you are 3.3 or later and using a 64 bit version of python you need to install the Microsoft SDK 7.1 that ships a 64 bit compiler and follow the directions here Python PIP has issues with path for MS Visual Studio 2010 Express for 64-bit install on Windows 7

1. First open your cmd

2. Then go to php folder directory, Suppose your php folder is in xampp folder on your c drive. Your command would then be:

   cd c:\xampp\php
   

3. After that, check your version:

   php -v
   

This should give the following output:

std::vector has random-access iterators. You can do pointer arithmetic with them. In particular, this my_vec.begin() + my_vec.size() == my_vec.end() always holds. So you could do

const vector<type>::const_iterator pos = std::find_if( firstVector.begin()
                                                     , firstVector.end()
                                                     , some_predicate(parameter) );
if( position != firstVector.end() ) {
    const vector<type>::size_type idx = pos-firstVector.begin();
    doAction( secondVector[idx] );
}

As an alternative, there's always std::numeric_limits<vector<type>::size_type>::max() to be used as an invalid value.

They are the same concepts, apart from the NULL value returned.

Windows

On Windows you need to include the gl.h header for OpenGL 1.1 support and link against OpenGL32.lib. Both are a part of the Windows SDK. In addition, you might want the following headers which you can get from http://www.opengl.org/registry .

• <GL/glext.h> - OpenGL 1.2 and above compatibility profile and extension interfaces..
• <GL/glcorearb.h> - OpenGL core profile and ARB extension interfaces, as described in appendix G.2 of the OpenGL 4.3 Specification. Does not include interfaces found only in the compatibility profile.
• <GL/glxext.h> - GLX 1.3 and above API and GLX extension interfaces.
• <GL/wglext.h> - WGL extension interfaces.

Linux

On Linux you need to link against libGL.so, which is usually a symlink to libGL.so.1, which is yet a symlink to the actual library/driver which is a part of your graphics driver. For example, on my system the actual driver library is named libGL.so.256.53, which is the version number of the nvidia driver I use. You also need to include the gl.h header, which is usually a part of a Mesa or Xorg package. Again, you might need glext.h and glxext.h from http://www.opengl.org/registry . glxext.h holds GLX extensions, the equivalent to wglext.h on Windows.

If you want to use OpenGL 3.x or OpenGL 4.x functionality without the functionality which were moved into the GL_ARB_compatibility extension, use the new gl3.h header from the registry webpage. It replaces gl.h and also glext.h (as long as you only need core functionality).

Last but not the least, glaux.h is not a header associated with OpenGL. I assume you've read the awful NEHE tutorials and just went along with it. Glaux is a horribly outdated Win32 library (1996) for loading uncompressed bitmaps. Use something better, like libPNG, which also supports alpha channels.

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:

<form method="post" enctype="multipart/form-data" action="/upload">
    <input type="file" name="file">
    <input type="submit" value="Submit">
</form>

Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:

const http = require("http");
const path = require("path");
const fs = require("fs");

const express = require("express");

const app = express();
const httpServer = http.createServer(app);

const PORT = process.env.PORT || 3000;

httpServer.listen(PORT, () => {
  console.log(`Server is listening on port ${PORT}`);
});

// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));

Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).

In Express 3.x you could use express.bodyParser middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:

You need to define a route to handle form posts:

const multer = require("multer");

const handleError = (err, res) => {
  res
    .status(500)
    .contentType("text/plain")
    .end("Oops! Something went wrong!");
};

const upload = multer({
  dest: "/path/to/temporary/directory/to/store/uploaded/files"
  // you might also want to set some limits: https://github.com/expressjs/multer#limits
});


app.post(
  "/upload",
  upload.single("file" /* name attribute of <file> element in your form */),
  (req, res) => {
    const tempPath = req.file.path;
    const targetPath = path.join(__dirname, "./uploads/image.png");

    if (path.extname(req.file.originalname).toLowerCase() === ".png") {
      fs.rename(tempPath, targetPath, err => {
        if (err) return handleError(err, res);

        res
          .status(200)
          .contentType("text/plain")
          .end("File uploaded!");
      });
    } else {
      fs.unlink(tempPath, err => {
        if (err) return handleError(err, res);

        res
          .status(403)
          .contentType("text/plain")
          .end("Only .png files are allowed!");
      });
    }
  }
);

In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.

In order to show the uploaded image, assuming you already have an HTML page containing an img element:

<img src="/image.png" />

you can define another route in your express app and use res.sendFile to serve the stored image:

app.get("/image.png", (req, res) => {
  res.sendFile(path.join(__dirname, "./uploads/image.png"));
});

You can rename/remove master on remote, but this will be an issue if lots of people have based their work on the remote master branch and have pulled that branch in their local repo.
That might not be the case here since everyone seems to be working on branch 'seotweaks'.

In that case you can:
git remote --show may not work. (Make a git remote show to check how your remote is declared within your local repo. I will assume 'origin')
(Regarding GitHub, house9 comments: "I had to do one additional step, click the 'Admin' button on GitHub and set the 'Default Branch' to something other than 'master', then put it back afterwards")

git branch -m master master-old  # rename master on local
git push origin :master          # delete master on remote
git push origin master-old       # create master-old on remote
git checkout -b master seotweaks # create a new local master on top of seotweaks
git push origin master           # create master on remote

But again:

• if other users try to pull while master is deleted on remote, their pulls will fail ("no such ref on remote")
• when master is recreated on remote, a pull will attempt to merge that new master on their local (now old) master: lots of conflicts. They actually need to reset --hard their local master to the remote/master branch they will fetch, and forget about their current master.

About promise composition vs. Rxjs, as this is a frequently asked question, you can refer to a number of previously asked questions on SO, among which :

• How to do the chain sequence in rxjs
• RxJS Promise Composition (passing data)
• RxJS sequence equvalent to promise.then()?

Basically, flatMap is the equivalent of Promise.then.

For your second question, do you want to replay values already emitted, or do you want to process new values as they arrive? In the first case, check the publishReplay operator. In the second case, standard subscription is enough. However you might need to be aware of the cold. vs. hot dichotomy depending on your source (cf. Hot and Cold observables : are there 'hot' and 'cold' operators? for an illustrated explanation of the concept)

@Timmmm, about your edit :

GET /timeline_posts     // could return the N first posts, with links to fetch the next/previous N posts

This would dramatically reduce the number of calls

And nothing prevents you from designing a server that accepts HTTP parameters to denote the field values your clients may want...

But this is a detail.

Much more important is the fact that you did not mention huge advantages of the REST architectural style (much better scalability, due to server statelessness; much better availability, due to server statelessness also; much better use of the standard services, such as caching for instance, when using a REST architectural style; much lower coupling between client and server, due to the use of a uniform interface; etc. etc.)

As for your remark

"Not all actions easily map to CRUD (create, read/retrieve, update, delete)."

: an RDBMS uses a CRUD approach, too (SELECT/INSERT/DELETE/UPDATE), and there is always a way to represent and act upon a data model.

Regarding your sentence

"You may not even be dealing with object type resources"

: a RESTful design is, by essence, a simple design - but this does NOT mean that designing it is simple. Do you see the difference ? You'll have to think a lot about the concepts your application will represent and handle, what must be done by it, if you prefer, in order to represent this by means of resources. But if you do so, you will end up with a more simple and efficient design.

For you to output foo {1, 2, 3} you have to do something like:

string t = "1, 2, 3";
string v = String.Format(" foo {{{0}}}", t);

To output a { you use {{ and to output a } you use }}.

or Now, you can also use c# string interpolation like this (feature available in C# 6.0)

Escaping Brackets: String Interpolation $(""). it is new feature in C# 6.0

var inVal = "1, 2, 3";
var outVal = $" foo {{{inVal}}}";
//Output will be:  foo {1, 2, 3}

Here's a less specific extension method that works with Image rather than doing the loading and saving for you. It also allows you to specify interpolation method and correctly renders edges when you use NearestNeighbour interpolation.

The image will be rendered within the bounds of the area you specify so you always know your output width and height. e.g:

namespace YourApp
{
    #region Namespaces
    using System;
    using System.Drawing;
    using System.Drawing.Imaging;
    using System.Drawing.Drawing2D;
    #endregion

    /// <summary>Generic helper functions related to graphics.</summary>
    public static class ImageExtensions
    {
        /// <summary>Resizes an image to a new width and height value.</summary>
        /// <param name="image">The image to resize.</param>

        /// <param name="mode">Interpolation mode.</param>
        /// <param name="maintainAspectRatio">If true, the image is centered in the middle of the returned image, maintaining the aspect ratio of the original image.</param>
        /// <returns>The new image. The old image is unaffected.</returns>
        public static Image ResizeImage(this Image image, int newWidth, int newHeight, InterpolationMode mode = InterpolationMode.Default, bool maintainAspectRatio = false)
        {
            Bitmap output = new Bitmap(newWidth, newHeight, image.PixelFormat);

            using (Graphics gfx = Graphics.FromImage(output))
            {
                gfx.Clear(Color.FromArgb(0, 0, 0, 0));
                gfx.InterpolationMode = mode;
                if (mode == InterpolationMode.NearestNeighbor)
                {
                    gfx.PixelOffsetMode = PixelOffsetMode.HighQuality;
                    gfx.SmoothingMode = SmoothingMode.HighQuality;
                }

                double ratioW = (double)newWidth / (double)image.Width;
                double ratioH = (double)newHeight / (double)image.Height;
                double ratio = ratioW < ratioH ? ratioW : ratioH;
                int insideWidth = (int)(image.Width * ratio);
                int insideHeight = (int)(image.Height * ratio);

                gfx.DrawImage(image, new Rectangle((newWidth / 2) - (insideWidth / 2), (newHeight / 2) - (insideHeight / 2), insideWidth, insideHeight));
            }

            return output;
        }
    }
}

The Java Virtual Machine takes two command line arguments which set the initial and maximum heap sizes: -Xms and -Xmx. You can add a system environment variable named _JAVA_OPTIONS, and set the heap size values there.
For example if you want a 512Mb initial and 1024Mb maximum heap size you could use:

under Windows:

SET _JAVA_OPTIONS = -Xms512m -Xmx1024m

under Linux:

export _JAVA_OPTIONS="-Xms512m -Xmx1024m"

It is possible to read the default JVM heap size programmatically by using totalMemory() method of Runtime class. Use following code to read JVM heap size.

public class GetHeapSize {
    public static void main(String[]args){

        //Get the jvm heap size.
        long heapSize = Runtime.getRuntime().totalMemory();

        //Print the jvm heap size.
        System.out.println("Heap Size = " + heapSize);
    }
}

Actually your command line arguments are practically like an array already. At least, you can treat the $@ variable much like an array. That said, you can convert it into an actual array like this:

myArray=( "$@" )

If you just want to type some arguments and feed them into the $@ value, use set:

$ set -- apple banana "kiwi fruit"
$ echo "$#"
3
$ echo "$@"
apple banana kiwi fruit

Understanding how to use the argument structure is particularly useful in POSIX sh, which has nothing else like an array.

looks like you're better off systeming out to system("grep \"$QUERY\"") since that script won't be particularly high performance either way. Otherwise http://php.net/manual/en/function.file.php shows you how to loop over lines and you can use http://php.net/manual/en/function.strstr.php for finding matches.

You can simply write your own code by using the mapping table here: http://www.timeanddate.com/time/zones/

or, use moment-timezone library: http://momentjs.com/timezone/docs/

See zone.name; // America/Los_Angeles

or, this library: https://github.com/Canop/tzdetect.js

You can use this function to get proper client IP:

public function getClientIP(){       
     if (array_key_exists('HTTP_X_FORWARDED_FOR', $_SERVER)){
            return  $_SERVER["HTTP_X_FORWARDED_FOR"];  
     }else if (array_key_exists('REMOTE_ADDR', $_SERVER)) { 
            return $_SERVER["REMOTE_ADDR"]; 
     }else if (array_key_exists('HTTP_CLIENT_IP', $_SERVER)) {
            return $_SERVER["HTTP_CLIENT_IP"]; 
     } 

     return '';
}

The files need to be in a JPEG or PNG format of 24 bits, in a 2:1 ratio if it is a portrait and a 16:9 ratio for landscapes. Be careful that if you go for different sizes: the maximum size should not be more than twice bigger than the minimum size.

I had some problems with the other solutions on this page, so thought I'd drop this in.

@Html.TextBoxFor(m => m.EndDate, "{0:d}", new { @class = "form-control datepicker" })

So you only need to add "{0:d}" in the second parameter and you should be good to go.

In Vim, use :insert. This will keep all your formatting and not do autoindenting. For more information help :insert.

As mentioned in Jonathan's answer, FETCH_HEAD corresponds to the file .git/FETCH_HEAD. Typically, the file will look like this:

71f026561ddb57063681109aadd0de5bac26ada9                        branch 'some-branch' of <remote URL>
669980e32769626587c5f3c45334fb81e5f44c34        not-for-merge   branch 'some-other-branch' of <remote URL>
b858c89278ab1469c71340eef8cf38cc4ef03fed        not-for-merge   branch 'yet-some-other-branch' of <remote URL>

Note how all branches but one are marked not-for-merge. The odd one out is the branch that was checked out before the fetch. In summary: FETCH_HEAD essentially corresponds to the remote version of the branch that's currently checked out.

The shortcuts preserve your cursor position and your comments as long as they start with # (there is space after #). For example:

# variable x
x = 0

After commenting:

# variable x
#x = 0

After uncomennting:

# variable x
x = 0

While not standard, I found that some of the JSON libraries have options to support multiline Strings. I am saying this with the caveat, that this will hurt your interoperability.

However in the specific scenario I ran into, I needed to make a config file that was only ever used by one system readable and manageable by humans. And opted for this solution in the end.

Here is how this works out on Java with Jackson:

JsonMapper mapper = JsonMapper.builder()
   .enable(JsonReadFeature.ALLOW_UNESCAPED_CONTROL_CHARS)
   .build()

url-pattern is used in web.xml to map your servlet to specific URL. Please see below xml code, similar code you may find in your web.xml configuration file.

<servlet>
    <servlet-name>AddPhotoServlet</servlet-name>  //servlet name
    <servlet-class>upload.AddPhotoServlet</servlet-class>  //servlet class
</servlet>
 <servlet-mapping>
    <servlet-name>AddPhotoServlet</servlet-name>   //servlet name
    <url-pattern>/AddPhotoServlet</url-pattern>  //how it should appear
</servlet-mapping>

If you change url-pattern of AddPhotoServlet from /AddPhotoServlet to /MyUrl. Then, AddPhotoServlet servlet can be accessible by using /MyUrl. Good for the security reason, where you want to hide your actual page URL.

Java Servlet url-pattern Specification:

1. A string beginning with a '/' character and ending with a '/*' suffix is used for path mapping.
2. A string beginning with a '*.' prefix is used as an extension mapping.
3. A string containing only the '/' character indicates the "default" servlet of the application. In this case the servlet path is the request URI minus the context path and the path info is null.
4. All other strings are used for exact matches only.

because your jQuery code is wrong. Correctly would be:

var theParent = $(this).parent().get(0); 
$(theParent).css('z-index', 3000);

I'm also coming from Ruby so I love the syntax foo ||= 7.

This is the closest thing I can find.

foo = foo if 'foo' in vars() else 7

I've seen people do this for a dict:

try:
    foo['bar']
except KeyError:
    foo['bar'] = 7

Upadate: However, I recently found this gem:

foo['bar'] = foo.get('bar', 7)

If you like that, then for a regular variable you could do something like this:

vars()['foo'] = vars().get('foo', 7)

Your calls are made recursively which pushes functions on to the stack infinitely that causes max call stack exceeded error due to recursive behavior. Instead try using setTimeout which is a callback.

Also based on your markup your selector is wrong. it should be #advisersDiv

Demo

function fadeIn() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).addClass("pulse");
    setTimeout(fadeOut,1); //<-- Provide any delay here
};

function fadeOut() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).removeClass("pulse");
    setTimeout(fadeIn,1);//<-- Provide any delay here
};
fadeIn();

Assign the response to a value and test the attributes of it. These should tell you something useful.

response = requests.post(url,params=data,headers=headers)
response.status_code
response.text

• status_code should just reconfirm the code you were given before, of course

If this is a stored procedure, you can do:

UPDATE `mysql`.`proc` SET definer = 'YournewDefiner' WHERE definer='OldDefinerShownBefore'

But this is not advised.

For me, better solution is to create the definer:

create user 'myuser' identified by 'mypass';
grant all on `mytable`.* to 'myuser' identified by 'mypass';

For me the solution was: Settings ? Version Control ? Git ? Use Credential helper

get days between two dates date is instance of java.util.Date

public static long daysBetweenTwoDates(Date dateFrom, Date dateTo) {
            return DAYS.between(Instant.ofEpochMilli(dateFrom.getTime()), Instant.ofEpochMilli(dateTo.getTime()));
        }

I came up with this function, which basically behaves similarly to one in the answer by Alex:

-(NSString*)trimLastSpace:(NSString*)str{
    int i = str.length - 1;
    for (; i >= 0 && [str characterAtIndex:i] == ' '; i--);
    return [str substringToIndex:i + 1];
}

whitespaceCharacterSet besides space itself includes also tab character, which in my case could not appear. So i guess a plain comparison could suffice.

In my case it was that the dependor project (the project depending upon the one in the error message) was missing values in its "Assembly version" fields under the project's "Properties ? Application ? Assembly Information...". I just added in the same numbers which were there for "File version", clicked "OK" and the compiler errors disappeared!

It turns out that re-adding the AssemblyVersion then building the project again resulted in another error claiming that it was already present in the project. It was! Under the properties node of the project in Solution Explorer, there was a "SolutionVersionInfo.cs" file which also contained an AssemblyVersion attribute - deleting this file from the project resolved this error.

To get dpi:

DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);

// will either be DENSITY_LOW, DENSITY_MEDIUM or DENSITY_HIGH
int dpiClassification = dm.densityDpi;

// these will return the actual dpi horizontally and vertically
float xDpi = dm.xdpi;
float yDpi = dm.ydpi;

For Perfect DateTime Match in SQL Server

SELECT ID FROM [Table Name] WHERE (DateLog between '2017-02-16 **00:00:00.000**' and '2017-12-16 **23:59:00.999**') ORDER BY DateLog DESC

You can submit form by just clicking on checkbox by simple method in JavaScript. Inside form tag or Input attribute add following attribute:

    onchange="this.form.submit()"

Example:

<form>
      <div>
           <input type="checkbox">
      </div>
</form>

In Python 3, urllib2 was replaced by two in-built modules named urllib.request and urllib.error

Adapted from source

So replace this:

import urllib2

With this:

import urllib.request as urllib2

Slightly building upon the answers of other people. Now allowing you to specify the file you want to read from and the variable you want the result put into:

@echo off
for /f "delims=" %%x in (%2) do (
set %1=%%x
exit /b
)

This means you can use the above like this (assuming you called it getline.bat)

c:\> dir > test-file
c:\> getline variable test-file
c:\> set variable  
variable= Volume in drive C has no label.

When compiling your program, you need to include dict.c as well, eg:

gcc -o test1 test1.c dict.c

Plus you have a typo in dict.c definition of CreateDictionary, it says CreateDectionary (e instead of i)

I updated my requirements.txt to have psycopg2==2.7.4 --no-binary=psycopg2 So that it build binaries on source

I use a slightly modified version of kolbyjack's second approach with ~ instead of ~*.

location ~ ^/service/ {
  proxy_pass http://apache/$uri$is_args$args;
}

Works like you want:

echo "A,B,C" | sed s/,/\',\'/g

It depends on windows system but usually:

1. you go to system properties
2. look at hardware devices
3. Right click on the yellow (has to be yellow if it's driver problem) icon representing your mobile device
4. select property
5. Then go on the driver tab
6. select update driver
7. choose the bottom selection find on local computer
8. then choose manually
9. From the windows opened look for driver disk the bottom right button
10. Choose the driver from the folder <sdk>\extras\google\usb_driver\i386 (or amd64 for and).
11. Remember to uncheck the show only compatible hardware.
12. Then choose the driver
13. When windows warn your about possible incompatibility go on.

For my mobile it works, but depend on your mobile if it work or not.

Hope this help, bye.

When I think of dummy variables I think of using them in the context of OLS regression, and I would do something like this:

import numpy as np
import pandas as pd
import statsmodels.api as sm

my_data = np.array([[5, 'a', 1],
                    [3, 'b', 3],
                    [1, 'b', 2],
                    [3, 'a', 1],
                    [4, 'b', 2],
                    [7, 'c', 1],
                    [7, 'c', 1]])                


df = pd.DataFrame(data=my_data, columns=['y', 'dummy', 'x'])
just_dummies = pd.get_dummies(df['dummy'])

step_1 = pd.concat([df, just_dummies], axis=1)      
step_1.drop(['dummy', 'c'], inplace=True, axis=1)
# to run the regression we want to get rid of the strings 'a', 'b', 'c' (obviously)
# and we want to get rid of one dummy variable to avoid the dummy variable trap
# arbitrarily chose "c", coefficients on "a" an "b" would show effect of "a" and "b"
# relative to "c"
step_1 = step_1.applymap(np.int) 

result = sm.OLS(step_1['y'], sm.add_constant(step_1[['x', 'a', 'b']])).fit()
print result.summary()

So i tried the above :javascript which works :) However HAML wraps the generated code in CDATA like so:

<script type="text/javascript">
  //<![CDATA[
    $(document).ready( function() {
       $('body').addClass( 'test' );
    } );
  //]]>
</script>

The following HAML will generate the typical tag for including (for example) typekit or google analytics code.

 %script{:type=>"text/javascript"}
  //your code goes here - dont forget the indent!

Try this method. It's very easy:

public static boolean setSsidAndPassword(Context context, String ssid, String ssidPassword) {
    try {
        WifiManager wifiManager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);
        Method getConfigMethod = wifiManager.getClass().getMethod("getWifiApConfiguration");
        WifiConfiguration wifiConfig = (WifiConfiguration) getConfigMethod.invoke(wifiManager);

        wifiConfig.SSID = ssid;
        wifiConfig.preSharedKey = ssidPassword;

        Method setConfigMethod = wifiManager.getClass().getMethod("setWifiApConfiguration", WifiConfiguration.class);
        setConfigMethod.invoke(wifiManager, wifiConfig);

        return true;
    } catch (Exception e) {
        e.printStackTrace();
        return false;
    }
}

With respect to easily importing the RSA private key, without using 3rd party code such as BouncyCastle, I think the answer is "No, not with a PEM of the private key alone."

However, as alluded to above by Simone, you can simply combine the PEM of the private key (*.key) and the certificate file using that key (*.crt) into a *.pfx file which can then be easily imported.

To generate the PFX file from the command line:

openssl pkcs12 -in a.crt -inkey a.key -export -out a.pfx

Then use normally with the .NET certificate class such as:

using System.Security.Cryptography.X509Certificates;

X509Certificate2 combinedCertificate = new X509Certificate2(@"C:\path\to\file.pfx");

Now you can follow the example from MSDN for encrypting and decrypting via RSACryptoServiceProvider:

I left out that for decrypting you would need to import using the PFX password and the Exportable flag. (see: BouncyCastle RSAPrivateKey to .NET RSAPrivateKey)

X509KeyStorageFlags flags = X509KeyStorageFlags.Exportable;
X509Certificate2 cert = new X509Certificate2("my.pfx", "somepass", flags);

RSACryptoServiceProvider rsa = (RSACryptoServiceProvider)cert.PrivateKey;
RSAParameters rsaParam = rsa.ExportParameters(true); 

This is what has finally served me

/** Set parent scroll to show element
 * @param element {object} The HTML object to show
 * @param parent {object} The HTML object where the element is shown  */
var scrollToView = function(element, parent) {
    //Algorithm: Accumulate the height of the previous elements and add half the height of the parent
    var offsetAccumulator = 0;
    parent = $(parent);
    parent.children().each(function() {
        if(this == element) {
            return false; //brake each loop
        }
        offsetAccumulator += $(this).innerHeight();
    });
    parent.scrollTop(offsetAccumulator - parent.innerHeight()/2);
}

You can make the output just 4 and 24 using unlist:

unlist(gregexpr(pattern ='2',"the2quickbrownfoxeswere2tired"))
[1]  4 24

You can use awk, sort & uniq to do this, for example to list all the unique values in the first column

awk < test.txt '{print $1}' | sort | uniq

As posted elsewhere, if you want to count the number of instances of something you can pipe the unique list into wc -l

I don't really understand some points such as :
a) business people needs to understand business very well, or;
b) disagreement on business people don't need to know the rule.

For me, as a people just touching BRE, the benefit of BRE is so called to let system adapt to business change, hence it's focused on adaptive of change.
Does it matter if the rule set up at time x is different from the rule set up at time y because of:
a) business people don't understand business, or;
b) business people don't understand rules?

you can try like that. try: self.assertRaises(None,function,arg1, arg2) except: pass if you don't put code inside try block it will through exception' AssertionError: None not raised " and test case will be failed. Test case will be pass if put inside try block which is expected behaviour.

There are number of ways to do it:

Using filter() (and operator)

query = meta.Session.query(User).filter(
    User.firstname.like(search_var1),
    User.lastname.like(search_var2)
    )

Using filter_by() (and operator)

query = meta.Session.query(User).filter_by(
    firstname.like(search_var1),
    lastname.like(search_var2)
    )

Chaining filter() or filter_by() (and operator)

query = meta.Session.query(User).\
    filter_by(firstname.like(search_var1)).\
    filter_by(lastname.like(search_var2))

Using or_(), and_(), and not()

from sqlalchemy import and_, or_, not_

query = meta.Session.query(User).filter(
    and_(
        User.firstname.like(search_var1),
        User.lastname.like(search_var2)
    )
)

.list-inline class in bootstrap is a Inline Unordered List.

If you want to create a horizontal menu using ordered or unordered list you need to place all list items in a single line i.e. side by side. You can do this by simply applying the class

<div class="list-inline">
    <a href="#" class="list-inline-item">First item</a>
    <a href="#" class="list-inline-item">Secound item</a>
    <a href="#" class="list-inline-item">Third item</a>
  </div>

you can use indexOf for this

var a = 'how are you';
if (a.indexOf('are') > -1) {
  return true;
} else {
  return false;
}

Edit: This is an old answer that keeps getting up votes every once in a while so I thought I should clarify that in the above code, the if clause is not required at all because the expression itself is a boolean. Here is a better version of it which you should use,

var a = 'how are you';
return a.indexOf('are') > -1;

Update in ECMAScript2016:

var a = 'how are you';
return a.includes('are');  //true

Since you should focus on usability and generalities in CSS, rather than use an id to point to a specific layout element (which results in huge or multiple css files) you should probably instead use a true class in your linked .css file:

.hidden {
visibility: hidden;
display: none;
}

or for the minimalist:

.hidden {
display: none;
}

Now you can simply apply it via:

<div class="hidden"> content </div>

Here are the CASE statement examples from the PostgreSQL docs (Postgres follows the SQL standard here):

SELECT a,
   CASE WHEN a=1 THEN 'one'
        WHEN a=2 THEN 'two'
        ELSE 'other'
   END
FROM test;

or

SELECT a,
   CASE a WHEN 1 THEN 'one'
          WHEN 2 THEN 'two'
          ELSE 'other'
   END
FROM test;

Obviously the second form is cleaner when you are just checking one field against a list of possible values. The first form allows more complicated expressions.

It's much better if you just use a <label>, hide the <input>, and customize the label.

HTML:

<input type="file" id="input">
<label for="input" id="label">Choose File</label>

CSS:

input#input{
    display: none;
}
label#label{
    /* Customize your label here */
}

You could just change this:

`create_date` TIMESTAMP NOT NULL DEFAULT '0000-00-00 00:00:00',

To something like this:

Use the Linux Command Line

Use the command line, as described in this related question: How do I check if my SSL Certificate is SHA1 or SHA2 on the commandline.

Command

Here's the command. Replace www.yoursite.com:443 to fit your needs. Default SSL port is 443:

openssl s_client -connect www.yoursite.com:443 < /dev/null 2>/dev/null \
    | openssl x509 -text -in /dev/stdin | grep "Signature Algorithm"

Results

This should return something like this for the sha1:

Signature Algorithm: sha1WithRSAEncryption

or this for the newer version:

Signature Algorithm: sha256WithRSAEncryption

Jquery later allowed you to to find the parents with the .parents() method.

Hence I recommend using:

var $div = $('#divid').parents('div[class^="div-a"]');

This gives all parent nodes matching the selector. To get the first parent matching the selector use:

var $div = $('#divid').parents('div[class^="div-a"]').eq(0);

You need to have one UISwipeGestureRecognizer for each direction. It's a little weird because the UISwipeGestureRecognizer.direction property is an options-style bit mask, but each recognizer can only handle one direction. You can send them all to the same handler if you want, and sort it out there, or send them to different handlers. Here's one implementation:

override func viewDidLoad() {
    super.viewDidLoad()

    let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(respondToSwipeGesture))
    swipeRight.direction = .right
    self.view.addGestureRecognizer(swipeRight)

    let swipeDown = UISwipeGestureRecognizer(target: self, action: #selector(respondToSwipeGesture))
    swipeDown.direction = .down
    self.view.addGestureRecognizer(swipeDown)
}

@objc func respondToSwipeGesture(gesture: UIGestureRecognizer) {

    if let swipeGesture = gesture as? UISwipeGestureRecognizer {

        switch swipeGesture.direction {
        case .right:
            print("Swiped right")
        case .down:
            print("Swiped down")
        case .left:
            print("Swiped left")
        case .up:
            print("Swiped up")
        default:
            break
        }
    }
}

Swift 3:

override func viewDidLoad() {
    super.viewDidLoad()

    let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture))
    swipeRight.direction = UISwipeGestureRecognizerDirection.right
    self.view.addGestureRecognizer(swipeRight)

    let swipeDown = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture))
    swipeDown.direction = UISwipeGestureRecognizerDirection.down
    self.view.addGestureRecognizer(swipeDown)
}

func respondToSwipeGesture(gesture: UIGestureRecognizer) {
    if let swipeGesture = gesture as? UISwipeGestureRecognizer {
        switch swipeGesture.direction {
        case UISwipeGestureRecognizerDirection.right:
            print("Swiped right")
        case UISwipeGestureRecognizerDirection.down:
            print("Swiped down")
        case UISwipeGestureRecognizerDirection.left:
            print("Swiped left")
        case UISwipeGestureRecognizerDirection.up:
            print("Swiped up")
        default:
            break
        }
    }
}

use this function anywhere easily:

 public static void setEditTextMaxLength(EditText editText, int length) {
    InputFilter[] FilterArray = new InputFilter[1];
    FilterArray[0] = new InputFilter.LengthFilter(length);
    editText.setFilters(FilterArray);
  }

With Keys and Values this works as well:

foreach ($array as $key => $value) {
    if ($value === end($array)) {
        echo "LAST ELEMENT!";
    }
}

An enum declares a set of ordered values - the typedef just adds a handy name to this. The 1st element is 0 etc.

typedef enum {
Monday=1,
...
} WORKDAYS;

WORKDAYS today = Monday;

The above is just an enumeration of shapeType tags.

I am using xampp 1.7.3. Using inspiration from here: xampp 1.7.3 upgrade broken virtual hosts access forbidden

INSTEAD OF add <Directory> .. </Directory> in httpd-vhosts.conf, I add it in httpd.conf right after <Directory "D:/xampplite/cgi-bin"> .. </Directory>.

Here is what I add in httpd.conf:

<Directory "D:/CofeeShop">
    AllowOverride All
    Options  All
    Order allow,deny
    Allow from all
</Directory>

And here is what I add in httpd-vhosts.conf

<VirtualHost *:8001>
    ServerAdmin [email protected]
    DocumentRoot "D:/CofeeShop"
    ServerName localhost:8001
</VirtualHost>

I also add Listen 8001 in httpd.conf to complete my setting.

Hope it helps

You need to have the database running before you create the users. For this you need multiple processes. You can either start postgres in a subshell (&) in the shell script, or use a tool like supervisord to run postgres and then run any initialization scripts.

A guide to supervisord and docker https://docs.docker.com/articles/using_supervisord/

I wrote a scheduler faster than cron. I have also implemented an overlapping guard. You can configure the scheduler to not start new process if previous one is still running. Take a look at https://github.com/sioux1977/scheduler/wiki

<module name="Checker">
    <module name="SuppressionCommentFilter"/>
    <module name="TreeWalker">
        <module name="FileContentsHolder"/>
    </module>
</module>

To configure a filter to suppress audit events between a comment containing line BEGIN GENERATED CODE and a comment containing line END GENERATED CODE:

<module name="SuppressionCommentFilter">
  <property name="offCommentFormat" value="BEGIN GENERATED CODE"/>
  <property name="onCommentFormat" value="END GENERATED CODE"/>
</module>

//BEGIN GENERATED CODE
@Override
public boolean equals(Object obj) { ... } // No violation events will be reported

@Override
public int hashCode() { ... } // No violation events will be reported
//END GENERATED CODE

You can do this a few ways. One, simply add this meta tag to your head:

<meta http-equiv="Cache-control" content="no-cache">

If you want to remove the document from cache, expires meta tag should work to delete it by setting its content attribute to -1 like so:

<meta http-equiv="Expires" content="-1">

http://www.metatags.org/meta_http_equiv_cache_control

Also, IE should give you the latest content for the main page. If you are having issues with external documents, like CSS and JS, add a dummy param at the end of your URLs with the current time in milliseconds so that it's never the same. This way IE, and other browsers, will always serve you the latest version. Here is an example:

<script src="mysite.com/js/myscript.js?12345">

UPDATE 1

After reading the comments I realize you wanted to programmatically erase the cache and not every time. What you could do is have a function in JS like:

eraseCache(){
  window.location = window.location.href+'?eraseCache=true';
}

Then, in PHP let's say, you do something like this:

<head>
<?php
    if (isset($_GET['eraseCache'])) {
        echo '<meta http-equiv="Cache-control" content="no-cache">';
        echo '<meta http-equiv="Expires" content="-1">';
        $cache = '?' . time();
    }
?>
<!-- ... other head HTML -->
<script src="mysite.com/js/script.js<?= $cache ?>"
</head>

This isn't tested, but should work. Basically, your JS function, if invoked, will reload the page, but adds a GET param to the end of the URL. Your site would then have some back-end code that looks for this param. If it exists, it adds the meta tags and a cache variable that contains a timestamp and appends it to the scripts and CSS that you are having caching issues with.

UPDATE 2

The meta tag indeed won't erase the cache on page load. So, technically you would need to run the eraseCache function in JS, once the page loads, you would need to load it again for the changes to take place. You should be able to fix this with your server side language. You could run the same eraseCache JS function, but instead of adding the meta tags, you need to add HTTP Cache headers:

<?php
    header("Cache-Control: no-cache, must-revalidate");
    header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
?>
<!-- Here you'd start your page... -->

This method works immediately without the need for page reload because it erases the cache before the page loads and also before anything is run.

I'd use a 'where not exists' -- exactly as you suggest in your title:

SELECT `voter`.`ID`, `voter`.`Last_Name`, `voter`.`First_Name`,
       `voter`.`Middle_Name`, `voter`.`Age`, `voter`.`Sex`,
       `voter`.`Party`, `voter`.`Demo`, `voter`.`PV`,
       `household`.`Address`, `household`.`City`, `household`.`Zip`
FROM (`voter`)
JOIN `household` ON `voter`.`House_ID`=`household`.`id`
WHERE `CT` = '5'
AND `Precnum` = 'CTY3'
AND  `Last_Name`  LIKE '%Cumbee%'
AND  `First_Name`  LIKE '%John%'

AND NOT EXISTS (
  SELECT * FROM `elimination`
   WHERE `elimination`.`voter_id` = `voter`.`ID`
)

ORDER BY `Last_Name` ASC
LIMIT 30

That may be marginally faster than doing a left join (of course, depending on your indexes, cardinality of your tables, etc), and is almost certainly much faster than using IN.

To remove trailing whitespace while also preserving whitespace-only lines, you want the regex to only remove trailing whitespace after non-whitespace characters. So you need to first check for a non-whitespace character. This means that the non-whitespace character will be included in the match, so you need to include it in the replacement.

Regex: ([^ \t\r\n])[ \t]+$

Replacement: \1 or $1, depending on the IDE

I am able to achieve the necessary code coverage exclusions by updating jacoco-maven-plugin configuration in pom.xml

                    </excludes>
                </configuration>
            </plugin>

this configuration excludes the GlobalExceptionHandler.java and ErrorResponse.java in the jacoco coverage.

And the following two lines does the same for sonar coverage .

    <sonar.exclusions> **/*GlobalExceptionHandler*.*, **/*ErrorResponse*.</sonar.exclusions>
        <sonar.coverage.exclusions> **/*GlobalExceptionHandler*.*, **/*ErrorResponse*.* </sonar.coverage.exclusions>

Update for 2018. You can use:

global $product;
echo wc_display_product_attributes( $product );

To customise the output, copy plugins/woocommerce/templates/single-product/product-attributes.php to themes/theme-child/woocommerce/single-product/product-attributes.php and modify that.

There are 2 solutions for this, but it return all columns separately:

import functools

dfs = [df1, df2, df3]

df_final = functools.reduce(lambda left,right: pd.merge(left,right,on='date'), dfs)
print (df_final)
          date     a_x   b_x       a_y      b_y   c_x         a        b   c_y
0  May 15,2017  900.00  0.2%  1,900.00  1000000  0.2%  2,900.00  2000000  0.2%

k = np.arange(len(dfs)).astype(str)
df = pd.concat([x.set_index('date') for x in dfs], axis=1, join='inner', keys=k)
df.columns = df.columns.map('_'.join)
print (df)
                0_a   0_b       1_a      1_b   1_c       2_a      2_b   2_c
date                                                                       
May 15,2017  900.00  0.2%  1,900.00  1000000  0.2%  2,900.00  2000000  0.2%

Sometimes you really want to set the axes limits before you plot the data. In that case, you can set the "autoscaling" feature of the Axes or AxesSubplot object. The functions of interest are set_autoscale_on, set_autoscalex_on, and set_autoscaley_on.

In your case, you want to freeze the y axis' limits, but allow the x axis to expand to accommodate your data. Therefore, you want to change the autoscaley_on property to False. Here is a modified version of the FFT subplot snippet from your code:

fft_axes = pylab.subplot(h,w,2)
pylab.title("FFT")
fft = scipy.fft(rawsignal)
pylab.ylim([0,1000])
fft_axes.set_autoscaley_on(False)
pylab.plot(abs(fft))

Have a look at ?options and use warn:

options( warn = -1 )

One question is if you also want to use git for the deploment of your projects. If so you probably would like to exclude your local sqlite file from the repository, same probably applies to file uploads (mostly in your media folder). (I'm talking about django now, since your question is also tagged with django)

Try this:

Calendar calendar = Calendar.getInstance();
calendar.setTime(yourdate);
int hours = calendar.get(Calendar.HOUR_OF_DAY);
int minutes = calendar.get(Calendar.MINUTE);
int seconds = calendar.get(Calendar.SECOND);

Edit:

hours, minutes, seconds

above will be the hours, minutes and seconds after converting yourdate to System Timezone!

Just in case anybody finds this, there's a nicer alternative that's not documented (I tripped over it after searching for hours, and finally found it in the bug list for the Android SDK itself). You CAN include raw HTML in strings.xml, as long as you wrap it in

<![CDATA[ ...raw html... ]]>

Example:

<string name="nice_html">
<![CDATA[
<p>This is a html-formatted string with <b>bold</b> and <i>italic</i> text</p>
<p>This is another paragraph of the same string.</p>
]]>
</string>

Then, in your code:

TextView foo = (TextView)findViewById(R.id.foo);
foo.setText(Html.fromHtml(getString(R.string.nice_html)));

IMHO, this is several orders of magnitude nicer to work with :-)

AttributeError is raised when attribute of the object is not available.

An attribute reference is a primary followed by a period and a name:

attributeref ::= primary "." identifier

To return a list of valid attributes for that object, use dir(), e.g.:

dir(scipy)

So probably you need to do simply: import scipy.sparse

or by pure js, see also on StackOverflow : JavaScript post request like a form submit

BUT WHY try to set $_session with js? any JS variable can be modified by a player with some 3rd party tools (firebug), thus any player can mod the $_session[]! And PHP cant give js any secret codes (or even [rolling] encrypted) to return, it is all visible. Jquery or AJAX can't help, it's all js in the end.

This happens in online game design a lot. (Maybe a bit of Game Theory? forgive me, I have a masters and love to put theory to use :) ) Like in crimegameonline.com, I initialize a minigame puzzle with PHP, saving the initial board in $_SESSION['foo']. Then, I use php to [make html that] shows the initial puzzle start. Then, js takes over, watching buttons and modding element xy's as players make moves. I DONT want to play client-server (like WOW) and ask the server 'hey, my player want's to move to xy, what should I do?'. It's a lot of bandwidth, I don't want the server that involved.

And I can just send POSTs each time the player makes an error (or dies). The player can block outgoing POSTs (and alter local JS vars to make it forget the out count) or simply modify outgoing POST data. YES, people will do this, especially if real money is involved.

If the game is small, you could send post updates EACH move (button click), 1-way, with post vars of the last TWO moves. Then, the server sanity checks last and cats new in a $_SESSION['allMoves']. If the game is massive, you could just send a 'halfway' update of all preceeding moves, and see if it matches in the final update's list.

Then, after a js thinks we have a win, add or mod a button to change pages:

document.getElementById('but1').onclick=Function("leave()");
...
function leave() {
    var line='crimegameonline-p9b.php';
    top.location.href=line;
}

Then the new page's PHP looks at $_SESSION['init'] and plays thru each of the $_SESSION['allMoves'] to see if it is really a winner. The server (PHP) must decide if it is really a winner, not the client (js).

This works

var Box = React.createClass({
    getInitialState: function() {
        return {
            color: 'white'
        };
    },

    changeColor: function() {
        var newColor = this.state.color == 'white' ? 'black' : 'white';
        this.setState({ color: newColor });
    },

    render: function() {
        return (
            <div>
                <div
                    className='box'
                    style={{background:this.state.color}}
                    onClick={this.changeColor}
                >
                    In here already
                </div>
            </div>
        );
    }
});

ReactDOM.render(<Box />, document.getElementById('div1'));
ReactDOM.render(<Box />, document.getElementById('div2'));
ReactDOM.render(<Box />, document.getElementById('div3'));

and in your css, delete the styles you have and put this

.box {
  width: 200px;
  height: 200px;
  border: 1px solid black;
  float: left;
}

You have to style the actual div you are calling onClick on. Give the div a className and then style it. Also remember to remove this block where you are rendering App into the dom, App is not defined

ReactDOM.render(<App />,document.getElementById('root'));

I believe that is important to set the height, so created this function:

def my_gauss(x, sigma=1, h=1, mid=0):
    from math import exp, pow
    variance = pow(sdev, 2)
    return h * exp(-pow(x-mid, 2)/(2*variance))

Where sigma is the standard deviation, h is the height and mid is the mean.

Here is the result using different heights and deviations:

Another option to consider is Zenity: http://freecode.com/projects/zenity.

I had a situation where I was developing a Python server application (no GUI component) and hence didn't want to introduce a dependency on any python GUI toolkits, but I wanted some of my debug scripts to be parameterized by input files and wanted to visually prompt the user for a file if they didn't specify one on the command line. Zenity was a perfect fit. To achieve this, invoke "zenity --file-selection" using the subprocess module and capture the stdout. Of course this solution isn't Python-specific.

Zenity supports multiple platforms and happened to already be installed on our dev servers so it facilitated our debugging/development without introducing an unwanted dependency.

Python 2.7 and find_name()

Here is an easy-to-read implementation of the chosen idea with some helper methods, which perhaps are more Pythonic and cleaner to use than "reverse_mapping". Requires Python >= 2.7.

To address some comments below, Enums are quite useful to prevent spelling mistakes in code, e.g. for state machines, error classifiers, etc.

def Enum(*sequential, **named):
  """Generate a new enum type. Usage example:

  ErrorClass = Enum('STOP','GO')
  print ErrorClass.find_name(ErrorClass.STOP)
    = "STOP"
  print ErrorClass.find_val("STOP")
    = 0
  ErrorClass.FOO     # Raises AttributeError
  """
  enums = { v:k for k,v in enumerate(sequential) } if not named else named

  @classmethod
  def find_name(cls, val):
    result = [ k for k,v in cls.__dict__.iteritems() if v == val ]
    if not len(result):
        raise ValueError("Value %s not found in Enum" % val)
    return result[0]

  @classmethod
  def find_val(cls, n):
    return getattr(cls, n)

  enums['find_val'] = find_val
  enums['find_name'] = find_name
  return type('Enum', (), enums)

Quoting Chris: "... when your program quits, any daemon threads are killed automatically.". I think that sums it up. You should be careful when you use them as they abruptly terminate when main program executes to completion.

You will certainly be able to do that using WITH clause, or use analytic functions available in Oracle SQL.

With some effort you'd be able to get anything out of them in terms of cycles as in ordinary procedural languages. Both approaches are pretty powerful compared to ordinary SQL.

http://www.dba-oracle.com/t_with_clause.htm

http://www.orafaq.com/node/55

It requires some effort though. Don't be afraid to post a concrete example.

Using simple pseudo table DUAL helps too.

Bundle is used to pass data between Activities. You can create a bundle, pass it to Intent that starts the activity which then can be used from the destination activity.

Ok, it sounds like you want to change the global CSS so which will effictively change all elements of a peticular style at once. I've recently learned how to do this myself from a Shawn Olson tutorial. You can directly reference his code here.

Here is the summary:

You can retrieve the stylesheets via document.styleSheets. This will actually return an array of all the stylesheets in your page, but you can tell which one you are on via the document.styleSheets[styleIndex].href property. Once you have found the stylesheet you want to edit, you need to get the array of rules. This is called "rules" in IE and "cssRules" in most other browsers. The way to tell what CSSRule you are on is by the selectorText property. The working code looks something like this:

var cssRuleCode = document.all ? 'rules' : 'cssRules'; //account for IE and FF
var rule = document.styleSheets[styleIndex][cssRuleCode][ruleIndex];
var selector = rule.selectorText;  //maybe '#tId'
var value = rule.value;            //both selectorText and value are settable.

Let me know how this works for ya, and please comment if you see any errors.

This is not only applicable in Modernizer. I see some site implement like below to check whether it has javascript support or not.

<body class="no-js">
    <script>document.body.classList.remove('no-js');</script>
    ...
</body>

If javascript support is there, then it will remove no-js class. Otherwise no-js will remain in the body tag. Then they control the styles in the css when no javascript support.

.no-js .some-class-name {

}

I've sorted this out using the cb.createQuery() (without the result type parameter):

public class Blah() {

    CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder();
    CriteriaQuery query = criteriaBuilder.createQuery();
    Root<Entity> root;
    Predicate whereClause;
    EntityManager entityManager;
    Class<Entity> domainClass;

    ... Methods to create where clause ...

    public Blah(EntityManager entityManager, Class<Entity> domainClass) {
        this.entityManager = entityManager;
        this.domainClass = domainClass;
        criteriaBuilder = entityManager.getCriteriaBuilder();
        query = criteriaBuilder.createQuery();
        whereClause = criteriaBuilder.equal(criteriaBuilder.literal(1), 1);
        root = query.from(domainClass);
    }

    public CriteriaQuery<Entity> getQuery() {
        query.select(root);
        query.where(whereClause);
        return query;
    }

    public CriteriaQuery<Long> getQueryForCount() {
        query.select(criteriaBuilder.count(root));
        query.where(whereClause);
        return query;
    }

    public List<Entity> list() {
        TypedQuery<Entity> q = this.entityManager.createQuery(this.getQuery());
        return q.getResultList();
    }

    public Long count() {
        TypedQuery<Long> q = this.entityManager.createQuery(this.getQueryForCount());
        return q.getSingleResult();
    }
}

Hope it helps :)

Not sure if the cleanest for long commands but certainly the easiest:

ssh user@host "cmd1; cmd2; cmd3"

Check the domain's web server for http://www.<domain>.com configuration for X-Frame-Options It is a security feature designed to prevent clickJacking attacks,

How Does clickJacking work?

1. The evil page looks exactly like the victim page.
2. Then it tricked users to enter their username and password.

Technically the evil has an iframe with the source to the victim page.

<html>
    <iframe src='victim_domain.com'/>
    <input id="username" type="text" style="display: none;"/>
    <input id="password" type="text" style="display: none;"/>
    <script>
        //some JS code that click jacking the user username and input from inside the iframe...
    <script/>
<html>

How the security feature work

If you want to prevent web server request to be rendered within an iframe add the x-frame-options

X-Frame-Options DENY

The options are:

1. SAMEORIGIN //allow only to my own domain render my HTML inside an iframe.
2. DENY //do not allow my HTML to be rendered inside any iframe
3. "ALLOW-FROM https://example.com/" //allow specific domain to render my HTML inside an iframe

This is IIS config example:

   <httpProtocol>
       <customHeaders>
           <add name="X-Frame-Options" value="SAMEORIGIN" />
       </customHeaders>
   </httpProtocol>

The solution to the question

If the web server activated the security feature it may cause a client-side SecurityError as it should.

Try this:

DateFormat.parse(String)

On windows it is easy to interact with your webcam with pygame:

from VideoCapture import Device
cam = Device()
cam.saveSnapshot('image.jpg')

I haven't tried using pygame on linux (all my linux boxen are servers without X), but this link might be helpful http://www.jperla.com/blog/post/capturing-frames-from-a-webcam-on-linux

I used it recently:

select 
substring(name,1,charindex(' ',name)-1) as Col1,
substring(name,charindex(' ',name)+1,len(name)) as Col2 
from TableName

Found this article on net, very relevant to this topic. So posting here.

ASP.NET Internals - Clearing ASP.NET Session variables

At times it is quite handy to get the auto increment primary key (id) of the row if it exists and 0 if it doesn't.

Here's how this can be done in a single query:

SELECT IFNULL(`id`, COUNT(*)) FROM WHERE ...

I'm going to give you an example of how I read REST headers for my controllers. My controllers only accept application/json as a request type if I have data that needs to be read. I suspect that your problem is that you have an application/octet-stream that Spring doesn't know how to handle.

Normally my controllers look like this:

@Controller
public class FooController {
    @Autowired
    private DataService dataService;

    @RequestMapping(value="/foo/", method = RequestMethod.GET)
    @ResponseBody
    public ResponseEntity<Data> getData(@RequestHeader String dataId){
        return ResponseEntity.newInstance(dataService.getData(dataId);
    }

Now there is a lot of code doing stuff in the background here so I will break it down for you.

ResponseEntity is a custom object that every controller returns. It contains a static factory allowing the creation of new instances. My Data Service is a standard service class.

The magic happens behind the scenes, because you are working with JSON, you need to tell Spring to use Jackson to map HttpRequest objects so that it knows what you are dealing with.

You do this by specifying this inside your <mvc:annotation-driven> block of your config

ObjectMapper is simply an extension of com.fasterxml.jackson.databind.ObjectMapper and is what Jackson uses to actually map your request from JSON into an object.

I suspect you are getting your exception because you haven't specified a mapper that can read an Octet-Stream into an object, or something that Spring can handle. If you are trying to do a file upload, that is something else entirely.

So my request that gets sent to my controller looks something like this simply has an extra header called dataId.

If you wanted to change that to a request parameter and use @RequestParam String dataId to read the ID out of the request your request would look similar to this:

contactId : {"fooId"} 

This request parameter can be as complex as you like. You can serialize an entire object into JSON, send it as a request parameter and Spring will serialize it (using Jackson) back into a Java Object ready for you to use.

Example In Controller:

@RequestMapping(value = "/penguin Details/", method = RequestMethod.GET)
@ResponseBody
public DataProcessingResponseDTO<Pengin> getPenguinDetailsFromList(
        @RequestParam DataProcessingRequestDTO jsonPenguinRequestDTO)

Request Sent:

jsonPengiunRequestDTO: {

    "search": {

}

which gets automatically serialized back into an DataProcessingRequestDTO object before being given to the controller ready for me to use.

As you can see, this is quite powerful allowing you to serialize your data from JSON to an object without having to write a single line of code. You can do this for @RequestParam and @RequestBody which allows you to access JSON inside your parameters or request body respectively.

Now that you have a concrete example to go off, you shouldn't have any problems once you change your request type to application/json.

select distinct table_name 
from information_schema.columns 
where column_name in ('ColumnA') 
and table_schema='YourDatabase';
and table_name in 
(
 select distinct table_name 
 from information_schema.columns 
 where column_name in ('ColumnB')
 and table_schema='YourDatabase';
);

That ^^ will get the tables with ColumnA AND ColumnB instead of ColumnA OR ColumnB like the accepted answer

Nor in MsSql

SELECT col1 AS o, e = CASE WHEN o < GETDATE() THEN o ELSE GETDATE() END 
FROM Table1

Returns:

Msg 207, Level 16, State 3, Line 1
Invalid column name 'o'.
Msg 207, Level 16, State 3, Line 1
Invalid column name 'o'.

However if I change to CASE WHEN col1... THEN col1 it works

If you only need the bool result, just use the return value and ignore the out parameter.

bool successfullyParsed = int.TryParse(str, out ignoreMe);
if (successfullyParsed){
    // ...
}

Edit: Meanwhile you can also have a look at the original source code:

System.Int32.TryParse

If i want to know how something is actually implemented, i'm using ILSpy to decompile the .NET-code.

This is the result:

// int
/// <summary>Converts the string representation of a number to its 32-bit signed integer equivalent. A return value indicates whether the operation succeeded.</summary>
/// <returns>true if s was converted successfully; otherwise, false.</returns>
/// <param name="s">A string containing a number to convert. </param>
/// <param name="result">When this method returns, contains the 32-bit signed integer value equivalent to the number contained in s, if the conversion succeeded, or zero if the conversion failed. The conversion fails if the s parameter is null, is not of the correct format, or represents a number less than <see cref="F:System.Int32.MinValue"></see> or greater than <see cref="F:System.Int32.MaxValue"></see>. This parameter is passed uninitialized. </param>
/// <filterpriority>1</filterpriority>
public static bool TryParse(string s, out int result)
{
    return Number.TryParseInt32(s, NumberStyles.Integer, NumberFormatInfo.CurrentInfo, out result);
}


// System.Number
internal unsafe static bool TryParseInt32(string s, NumberStyles style, NumberFormatInfo info, out int result)
{
    byte* stackBuffer = stackalloc byte[1 * 114 / 1];
    Number.NumberBuffer numberBuffer = new Number.NumberBuffer(stackBuffer);
    result = 0;
    if (!Number.TryStringToNumber(s, style, ref numberBuffer, info, false))
    {
        return false;
    }
    if ((style & NumberStyles.AllowHexSpecifier) != NumberStyles.None)
    {
        if (!Number.HexNumberToInt32(ref numberBuffer, ref result))
        {
            return false;
        }
    }
    else
    {
        if (!Number.NumberToInt32(ref numberBuffer, ref result))
        {
            return false;
        }
    }
    return true;
}

And no, i cannot see any Try-Catchs on the road:

I am about 8 years late, well...anyways, I don't really know what then() does but maybe MDN might have an answer. Actually, I might actually understand it a little more.

This will show you all the information (hopefully), you need. Unless someone already posted this link. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/then

The format is promise.prototype.then() The promise and prototype are kind of like variables but not like variables in javascript, I mean like other things go there like navigator.getBattery().then() where this one actually exists but is barely used on the web, this one shows statuses about the battery of the device, more information and more on MDN if you are curious.

My windows laptop has both the clients 32 & 64 bit I started facing all of sudden then I reordered the path variable like below

Before:

C:\app\oracle64\product\12.1.0\client_1\bin;
C:\app\oracle32\product\12.1.0\client_1\bin;

After:

C:\app\oracle32\product\12.1.0\client_1\bin;
C:\app\oracle64\product\12.1.0\client_1\bin;

started working... Hope this helps everyone.

A couple of years ago, we got a report that one of our web apps wasn't displaying correctly in Firefox. It turned out that the page contained a tag that looked like

<div style="..." ... style="...">

When faced with a repeated style attribute, IE combines both of the styles, while Firefox only uses one of them, hence the different behavior. I changed the tag to

<div style="...; ..." ...>

and sure enough, it fixed the problem! The moral of the story is that browsers have more consistent handling of valid HTML than of invalid HTML. So, fix your damn markup already! (Or use HTML Tidy to fix it.)

You don't need to iterate the array. Just:

>>> x = ['[email protected]', '[email protected]']
>>> x
['[email protected]', '[email protected]']
>>> x.remove('[email protected]')
>>> x
['[email protected]']

This will remove the first occurence that matches the string.

EDIT: After your edit, you still don't need to iterate over. Just do:

index = initial_list.index(item1)
del initial_list[index]
del other_list[index]

To get the modified date on a single file try:

$lastModifiedDate = (Get-Item "C:\foo.tmp").LastWriteTime

To compare with another:

$dateA= $lastModifiedDate 
$dateB= (Get-Item "C:\other.tmp").LastWriteTime

if ($dateA -ge $dateB) {
  Write-Host("C:\foo.tmp was modified at the same time or after C:\other.tmp")
} else {
  Write-Host("C:\foo.tmp was modified before C:\other.tmp")
}

You should be able to access the document in the IFRAME using the following code:

document.getElementById('myframe').contentWindow.document

However, you will not be able to do this if the page in the frame is loaded from a different domain (such as google.com). THis is because of the browser's Same Origin Policy.

As stated in this answer:

Application.Wait (Now + TimeValue("0:00:01"))

will wait for 1 second

This logging is specific to your application and not a general Java feature. What application(s) are you running?

It might be that this is coming from a specific logging library that you are using within your own code. If so, please post the details of which one you are using.

The combination of setting IFS and use of "$*" can do what you want. I'm using a subshell so I don't interfere with this shell's $IFS

(set -- *; IFS=,; echo "$*")

To capture the output,

output=$(set -- *; IFS=,; echo "$*")

I edited you fiddle you just need to add z-index to the front element and position it accordingly.

You could also grab the attributes with the getAttribute() method which will return the value of a specific HTML attribute.

var elem = document.getElementById('the-span');_x000D_
_x000D_
var typeId = elem.getAttribute('data-typeId');_x000D_
var type   = elem.getAttribute('data-type');_x000D_
var points = elem.getAttribute('data-points');_x000D_
var important = elem.getAttribute('data-important');_x000D_
_x000D_
console.log(`typeId: ${typeId} | type: ${type} | points: ${points} | important: ${important}`_x000D_
);

<span data-typeId="123" data-type="topic" data-points="-1" data-important="true" id="the-span"></span>

As mentioned in the error, the official manual and the comments:

Replace

public function TSStatus($host, $queryPort)

with

public function __construct($host, $queryPort)

Default values are only used if the arguments are not specified. In your case you did specify the arguments - both were supplied, with a value of NULL. (Yes, in this case NULL is considered a real value :-). Try:

EXEC TEST()

Share and enjoy.

Addendum: The default values for procedure parameters are certainly buried in a system table somewhere (see the SYS.ALL_ARGUMENTS view), but getting the default value out of the view involves extracting text from a LONG field, and is probably going to prove to be more painful than it's worth. The easy way is to add some code to the procedure:

CREATE OR REPLACE PROCEDURE TEST(X IN VARCHAR2 DEFAULT 'P',
                                 Y IN NUMBER DEFAULT 1)
AS
  varX VARCHAR2(32767) := NVL(X, 'P');
  varY NUMBER          := NVL(Y, 1);
BEGIN
  DBMS_OUTPUT.PUT_LINE('X=' || varX || ' -- ' || 'Y=' || varY);
END TEST;

TL;TR;

This is the solution of your problem:

git remote update --prune    # To update all remotes
git branch -r                # To display remote branches

or:

git remote update --prune    # To update all remotes
git branch <TAB>             # To display all branches

JSON.stringify takes more optional arguments.

Try:

 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, 4); // Indented 4 spaces
 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, "\t"); // Indented with tab

From:

How can I beautify JSON programmatically?

Should work in modern browsers, and it is included in json2.js if you need a fallback for browsers that don't support the JSON helper functions. For display purposes, put the output in a <pre> tag to get newlines to show.

Have a look at the following

@using (Html.BeginForm("FileUpload", "Home", FormMethod.Post, 
                            new { enctype = "multipart/form-data" }))
{  
    <label for="file">Upload Image:</label> 
    <input type="file" name="file" id="file" style="width: 100%;" /> 
    <input type="submit" value="Upload" class="submit" /> 
}

your controller should have action method which would accept HttpPostedFileBase;

 public ActionResult FileUpload(HttpPostedFileBase file)
    {
        if (file != null)
        {
            string pic = System.IO.Path.GetFileName(file.FileName);
            string path = System.IO.Path.Combine(
                                   Server.MapPath("~/images/profile"), pic); 
            // file is uploaded
            file.SaveAs(path);

            // save the image path path to the database or you can send image 
            // directly to database
            // in-case if you want to store byte[] ie. for DB
            using (MemoryStream ms = new MemoryStream()) 
            {
                 file.InputStream.CopyTo(ms);
                 byte[] array = ms.GetBuffer();
            }

        }
        // after successfully uploading redirect the user
        return RedirectToAction("actionname", "controller name");
    }

Update 1

In case you want to upload files using jQuery with asynchornously, then try this article.

the code to handle the server side (for multiple upload) is;

 try
    {
        HttpFileCollection hfc = HttpContext.Current.Request.Files;
        string path = "/content/files/contact/";

        for (int i = 0; i < hfc.Count; i++)
        {
            HttpPostedFile hpf = hfc[i];
            if (hpf.ContentLength > 0)
            {
                string fileName = "";
                if (Request.Browser.Browser == "IE")
                {
                    fileName = Path.GetFileName(hpf.FileName);
                }
                else
                {
                    fileName = hpf.FileName;
                }
                string fullPathWithFileName = path + fileName;
                hpf.SaveAs(Server.MapPath(fullPathWithFileName));
            }
        }

    }
    catch (Exception ex)
    {
        throw ex;
    }

this control also return image name (in a javascript call back) which then you can use it to display image in the DOM.

UPDATE 2

Alternatively, you can try Async File Uploads in MVC 4.

This also helps when you have previous stack activity stored in stack.

I have modified Sudheesh's answer

boolean doubleBackToExitPressedOnce = false;

@Override
public void onBackPressed() {
    if (doubleBackToExitPressedOnce) {
        //super.onBackPressed();

  Intent intent = new Intent(Intent.ACTION_MAIN);
                    intent.addCategory(Intent.CATEGORY_HOME);
                    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);//***Change Here***
                    startActivity(intent);
                    finish();
                    System.exit(0);
        return;
    }

    this.doubleBackToExitPressedOnce = true;
    Toast.makeText(this, "Please click BACK again to exit", Toast.LENGTH_SHORT).show();

    new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
            doubleBackToExitPressedOnce=false;                       
        }
    }, 2000);
} 

There is also a tool that oracle made called mysqlshow

If you run it with the --k keys $table_name option it will display the keys.

SYNOPSIS
   mysqlshow [options] [db_name [tbl_name [col_name]]]
.......
.......
.......
·   --keys, -k
   Show table indexes.

example:

?-?  mysqlshow -h 127.0.0.1 -u root -p --keys database tokens

More concise than others:

def parseString(string):
    try:
        return int(string)
    except ValueError:
        return string

b = [[parseString(s) for s in clause.split(', ')] for clause in a]

Alternatively if your format is fixed as <string>, <int>, <int>, you can be even more concise:

def parseClause(a,b,c):
    return [a, int(b), int(c)]

b = [parseClause(*clause) for clause in a]

Quick and dirty, and store it in a variable:

USER=somebody
USER_HOME="$(echo -n $(bash -c "cd ~${USER} && pwd"))"

You cannot update UI from any other thread other than the UI thread. Use this to update thread on the UI thread.

 private void AggiornaContatore()
 {         
     if(this.lblCounter.InvokeRequired)
     {
         this.lblCounter.BeginInvoke((MethodInvoker) delegate() {this.lblCounter.Text = this.index.ToString(); ;});    
     }
     else
     {
         this.lblCounter.Text = this.index.ToString(); ;
     }
 }

The warning from your compiler is telling you that your format specifier doesn't match the data type you're passing to it.

Try using %lx or %llx. For more portability, include inttypes.h and use the PRIx64 macro.

For example: printf("val = 0x%" PRIx64 "\n", val); (note that it's string concatenation)

put export { Home }; at the end of the Home.js file

We can easily get the millisecond offset of a TimeZone with only a TimeZone instance and System.currentTimeMillis(). Then we can convert from milliseconds to any time unit of choice using the TimeUnit class.

Like so:

public static int getOffsetHours(TimeZone timeZone) {
    return (int) TimeUnit.MILLISECONDS.toHours(timeZone.getOffset(System.currentTimeMillis()));
}

Or if you prefer the new Java 8 time API

public static ZoneOffset getOffset(TimeZone timeZone) { //for using ZoneOffsett class
    ZoneId zi = timeZone.toZoneId();
    ZoneRules zr = zi.getRules();
    return zr.getOffset(LocalDateTime.now());
}

public static int getOffsetHours(TimeZone timeZone) { //just hour offset
    ZoneOffset zo = getOffset(timeZone);
    TimeUnit.SECONDS.toHours(zo.getTotalSeconds());
}

These are the conversions for setting the text color opacity levels.

• 100%: FF
• 87%: DE
• 70%: B3
• 54%: 8A
• 50%: 80
• 38%: 61
• 12%: 1F

Dark text on light backgrounds

• Primary text: DE000000
• Secondary text: 8A000000
• Disabled text, hint text, and icons: 61000000
• Dividers: 1F000000

White text on dark backgrounds

• Primary text: FFFFFFFF
• Secondary text: B3FFFFFF
• Disabled text, hint text, and icons: 80FFFFFF
• Dividers: 1FFFFFFF

• Look up any percentage here.

%RANDOM% gives you a random number between 0 and 32767.

Using an expression like SET /A test=%RANDOM% * 100 / 32768 + 1, you can change the range to anything you like (here the range is [1…100] instead of [0…32767]).

export {MyFunction1, MyFunction2, MyFunction3};

// Import
import * as myFns from "./my-functions";

myFns.MyFunction1();

// OR Import it as Destructured
import { MyFunction1, MyFunction2, MyFunction3 } from "./my-functions";

// AND you can use it like below with brackets (Parentheses) if it's a function

Here is my solution:

dependencies: Gmaps.js, jQuery

var Maps = function($) {
   var lost_addresses = [],
       geocode_count  = 0;

   var addMarker = function() { console.log('Marker Added!') };

   return {
     getGecodeFor: function(addresses) {
        var latlng;
        lost_addresses = [];
        for(i=0;i<addresses.length;i++) {
          GMaps.geocode({
            address: addresses[i],
            callback: function(response, status) {
              if(status == google.maps.GeocoderStatus.OK) {
                addMarker();
              } else if(status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
                lost_addresses.push(addresses[i]);
              }

               geocode_count++;
               // notify listeners when the geocode is done
               if(geocode_count == addresses.length) {
                 $.event.trigger({ type: 'done:geocoder' });
               }
            }
          });
        }
     },
     processLostAddresses: function() {
       if(lost_addresses.length > 0) {
         this.getGeocodeFor(lost_addresses);
       }
     }
   };
}(jQuery);

Maps.getGeocodeFor(address);

// listen to done:geocode event and process the lost addresses after 1.5s
$(document).on('done:geocode', function() {
  setTimeout(function() {
    Maps.processLostAddresses();
  }, 1500);
});

using LINQ and Lamba, i wanted to return two field values and assign it to single entity object field;

as Name = Fname + " " + LName;

See my below code which is working as expected; hope this is useful;

Myentity objMyEntity = new Myentity
{
id = obj.Id,
Name = contxt.Vendors.Where(v => v.PQS_ID == obj.Id).Select(v=> new { contact = v.Fname + " " + v.LName}).Single().contact
}

no need to declare the 'contact'

In PostgreSQL there is no merge command, and actually writing it is not trivial - there are actually strange edge cases that make the task "interesting".

The best (as in: working in the most possible conditions) approach, is to use function - such as one shown in manual (merge_db).

If you don't want to use function, you can usually get away with:

updated = db.execute(UPDATE ... RETURNING 1)
if (!updated)
  db.execute(INSERT...)

Just remember that it is not fault proof and it will fail eventually.

If your project's source code has import statements that reference classes that are in widget.jar, you should add the jar to your projects Compile-time Libraries. (The jar widget.jar will automatically be added to your project's Run-time Libraries). That corresponds to (1).

If your source code has imports for classes in some other jar and the source code for those classes has import statements that reference classes in widget.jar, you should add widget.jar to the Run-time libraries list. That corresponds to (2).

You can add the jars directly to the Libraries list in the project properties. You can also create a Library that contains the jar file and then include that Library in the Compile-time or Run-time Libraries list.

If you create a NetBeans Library for widget.jar, you can also associate source code for the jar's content and Javadoc for the APIs defined in widget.jar. This additional information about widget.jar will be used by NetBeans as you debug code. It will also be used to provide addition information when you use code completion in the editor.

You should avoid using Tools >> Java Platform to add a jar to a project. That dialog allows you to modify the classpath that is used to compile and run all projects that use the Java Platform that you create. That may be useful at times but hides your project's dependency on widget.jar almost completely.

You want to do #include <string> instead of string.h and then the type string lives in the std namespace, so you will need to use std::string to refer to it.

Another important difference, that wasn't mentioned in any answer above, is that there is no equality operator for json type, but there is one for jsonb.

This means that you can't use DISTINCT keyword when selecting this json-type and/or other fields from a table (you can use DISTINCT ON instead, but it's not always possible because of cases like this).

One can implement a Builder pattern with nested class. Especially in C++, personally I find it semantically cleaner. For example:

class Product{
    public:
        class Builder;
}
class Product::Builder {
    // Builder Implementation
}

Rather than:

class Product {}
class ProductBuilder {}

Yes, according to RFC 3696 apostrophes are valid as long as they come before the @ symbol.

You can use

git filter-branch --index-filter 'git rm -r --cached --ignore-unmatch <file/dir>' HEAD

This will delete everything in the history of that file. The problem is that the file is present in the history.

This command changes the hashes of your commits which can be a real problem, especially on shared repositories. It should not be performed without understanding the consequences.

You somehow have to refer to the variable you want to print the name of. So it would look like:

print varname(something_else)

There is no such function, but if there were it would be kind of pointless. You have to type out something_else, so you can as well just type quotes to the left and right of it to print the name as a string:

print "something_else"

http://www.program-transformation.org/Transform/VisualBasicDecompilers

This link provides a lot of resources for VB6 Decompiling, but it seems like it will depend greatly on what you DO have (do you still have the pre-link Object code [EDIT: er... p-code I mean], or just the EXE?) Either way, it looks like there's something, take a look in there.

You can't do it with "anonymous" type parameters (ie, wildcards that use ?), but you can do it with "named" type parameters. Simply declare the type parameter at method or class level.

import java.util.List;
interface A{}
interface B{}
public class Test<E extends B & A, T extends List<E>> {
    T t;
}

assume series s

s = pd.Series(np.arange(100))

Get quantiles for [.1, .2, .3, .4, .5, .6, .7, .8, .9]

s.quantile(np.linspace(.1, 1, 9, 0))

I had the same problem try this: python manage.py sqlsequencereset table_name

Eg:

python manage.py sqlsequencereset auth

you need to run this in production settings(if you have) and you need Postgres installed to run this on the server

PHP and references are somewhat unintuitive. If used appropriately references in the right places can provide large performance improvements or avoid very ugly workarounds and unusual code.

The following will produce an error:

 function f(&$v){$v = true;}
 f(&$v);

 function f($v){$v = true;}
 f(&$v);

None of these have to fail as they could follow the rules below but have no doubt been removed or disabled to prevent a lot of legacy confusion.

If they did work, both involve a redundant conversion to reference and the second also involves a redundant conversion back to a scoped contained variable.

The second one used to be possible allowing a reference to be passed to code that wasn't intended to work with references. This is extremely ugly for maintainability.

This will do nothing:

 function f($v){$v = true;}
 $r = &$v;
 f($r);

More specifically, it turns the reference back into a normal variable as you have not asked for a reference.

This will work:

 function f(&$v){$v = true;}
 f($v);

This sees that you are passing a non-reference but want a reference so turns it into a reference.

What this means is that you can't pass a reference to a function where a reference is not explicitly asked for making it one of the few areas where PHP is strict on passing types or in this case more of a meta type.

If you need more dynamic behaviour this will work:

 function f(&$v){$v = true;}
 $v = array(false,false,false);
 $r = &$v[1];
 f($r);

Here it sees that you want a reference and already have a reference so leaves it alone. It may also chain the reference but I doubt this.

When you installed MySQL it generated a password for the root user. You can connect using

/usr/local/mysql/bin/mysql -u root -p

and type in the generated password.

Previously, the root user in MySQL used to not have a password and could only connect from localhost. So you would connect using

/usr/local/mysql/bin/mysql -u root

There's no such thing as a global variable in C#. Period.

You can have static members if you want:

public static class MyStaticValues
{
   public static bool MyStaticBool {get;set;}
}

Try below code :

Assign the path of the folder to variable FolderPath before running the below code.

Sub sample()

    Dim FolderPath As String, path As String, count As Integer
    FolderPath = "C:\Documents and Settings\Santosh\Desktop"

    path = FolderPath & "\*.xls"

    Filename = Dir(path)

    Do While Filename <> ""
       count = count + 1
        Filename = Dir()
    Loop

    Range("Q8").Value = count
    'MsgBox count & " : files found in folder"
End Sub

In my case I got the error as

node_modules/@types/es6-promise/index.d.ts(11,15): error TS2300: Duplicate identifier 'Promise'.

And I had @types/es6-promise on my package.json but my tsconfig was already with target: "es6". So I guess there was a conflict with Promise when compiling.

Removing @types/es6-promise from my package.json file solved the issue.

There is a new open-source effort to develop a Java library for push notifications on Android, using the Meteor comet server as a backend. You can check it out at the Deacon Project Blog. We need developers, so please spread the word!

An abstract class is like the normal class it contains variables it contains protected variables functions it contains constructor only one thing is different it contains abstract method.

The abstract method means an empty method without definition so only one difference in abstract class we can not create an object of abstract class

Abstract must contains the abstract method and those methods must be defined in its inheriting class.

There is culture problem in regex in C# rather then js. So we need to use regex in US mode for email check. If you don't use ECMAScript mode, your language special characters are imply in A-Z with regex.

Regex.IsMatch(email, @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9_\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$", RegexOptions.ECMAScript)

For Bootstrap 4

If you are using input group in Bootstrap, you need to attach the new date to parent of the textbox, otherwise if you click on the calendar icon and click outside the date will be cleared.

<div class="input-group date" id="my-date-component">
   <input type="text" />
    <div class="input-group-append">
      <span class="input-group-text"><i class="fa fa-calendar"></i></span>
    </div>
</div>

You need to set date to input-group.date.

$('#my-date-component').datepicker("update", new Date("01/10/2014"));

Also check datepicker update method

For curves with not too much noise, I recommend the following small code snippet:

from numpy import *

# example data with some peaks:
x = linspace(0,4,1e3)
data = .2*sin(10*x)+ exp(-abs(2-x)**2)

# that's the line, you need:
a = diff(sign(diff(data))).nonzero()[0] + 1 # local min+max
b = (diff(sign(diff(data))) > 0).nonzero()[0] + 1 # local min
c = (diff(sign(diff(data))) < 0).nonzero()[0] + 1 # local max


# graphical output...
from pylab import *
plot(x,data)
plot(x[b], data[b], "o", label="min")
plot(x[c], data[c], "o", label="max")
legend()
show()

The +1 is important, because diff reduces the original index number.

This error sometimes occurs in a situation like this:

#ifndef NAN
#include <stdlib.h>
#define NAN (strtod("NAN",NULL))
#endif

static void init_random(uint32_t initseed=0)
{
    if (initseed==0)
    {
        struct timeval tv;
        gettimeofday(&tv, NULL);
        seed=(uint32_t) (4223517*getpid()*tv.tv_sec*tv.tv_usec);
    }
    else
        seed=initseed;
#if !defined(CYGWIN) && !defined(__INTERIX)
    //seed=42
    //SG_SPRINT("initializing random number generator with %d (seed size %d)\n", seed, RNG_SEED_SIZE)
    initstate(seed, CMath::rand_state, RNG_SEED_SIZE);
#endif
}

If the following code lines not run in the run-time:

#ifndef NAN
#include <stdlib.h>
#define NAN (strtod("NAN",NULL))
#endif

you will face with an error in your code like something as follows; because initstate is placed in the stdlib.h file and it's not included:

In file included from ../../shogun/features/SubsetStack.h:14:0, 
                 from ../../shogun/features/Features.h:21, 
                 from ../../shogun/ui/SGInterface.h:7, 
                 from MatlabInterface.h:15, 
                 from matlabInterface.cpp:7: 
../../shogun/mathematics/Math.h: In static member function 'static void shogun::CMath::init_random(uint32_t)': 
../../shogun/mathematics/Math.h:459:52: error: 'initstate' was not declared in this scope

You have extra spaces after END; that cause the heredoc not terminated.

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

I suggest Arrays.toString(byte_array);

It depends on your purpose. For example, I wanted to save a byte array exactly like the format you can see at time of debug that is something like this : [1, 2, 3] If you want to save exactly same value without converting the bytes to character format, Arrays.toString (byte_array) does this,. But if you want to save characters instead of bytes, you should use String s = new String(byte_array). In this case, s is equal to equivalent of [1, 2, 3] in format of character.

You will want to use a CONVERT() statement.

Try the following;

SELECT CONVERT(VARCHAR(10), SA.[RequestStartDate], 103) as 'Service Start Date', CONVERT(VARCHAR(10), SA.[RequestEndDate], 103) as 'Service End Date', FROM (......) SA WHERE.....

See MSDN Cast and Convert for more information.

This question might still be visited often enough that it's worth offering an addendum to Mr Kassies' answer. The dict built-in class can be sub-classed so that a default is returned for 'missing' keys. This mechanism works well for pandas. But see below.

In this way it's possible to avoid key errors.

>>> import pandas as pd
>>> data = { 'ID': [ 101, 201, 301, 401 ] }
>>> df = pd.DataFrame(data)
>>> class SurnameMap(dict):
...     def __missing__(self, key):
...         return ''
...     
>>> surnamemap = SurnameMap()
>>> surnamemap[101] = 'Mohanty'
>>> surnamemap[301] = 'Drake'
>>> df['Surname'] = df['ID'].apply(lambda x: surnamemap[x])
>>> df
    ID  Surname
0  101  Mohanty
1  201         
2  301    Drake
3  401         

The same thing can be done more simply in the following way. The use of the 'default' argument for the get method of a dict object makes it unnecessary to subclass a dict.

>>> import pandas as pd
>>> data = { 'ID': [ 101, 201, 301, 401 ] }
>>> df = pd.DataFrame(data)
>>> surnamemap = {}
>>> surnamemap[101] = 'Mohanty'
>>> surnamemap[301] = 'Drake'
>>> df['Surname'] = df['ID'].apply(lambda x: surnamemap.get(x, ''))
>>> df
    ID  Surname
0  101  Mohanty
1  201         
2  301    Drake
3  401         

This exception is also thrown when a non-existent property is being updated dynamically, using reflection.

If one is using reflection to dynamically update property values, it's worth checking to make sure the passed PropertyName is identical to the actual property.

In my case, I was attempting to update Employee.firstName, but the property was actually Employee.FirstName.

Worth keeping in mind. :)

1. Download the latest build from https://github.com/macvim-dev/macvim/releases

2. Expand the archive.

3. Put MacVim.app into /Applications/.

Done.

For paths greater than 260:
you can use:

Get-ChildItem | Where-Object {$_.FullName.Length -gt 260}

Example on 14 chars:
To view the paths lengths:

Get-ChildItem | Select-Object -Property FullName, @{Name="FullNameLength";Expression={($_.FullName.Length)}

Get paths greater than 14:

Get-ChildItem | Where-Object {$_.FullName.Length -gt 14}  

Screenshot:

For filenames greater than 10:

Get-ChildItem | Where-Object {$_.PSChildName.Length -gt 10}

I had the same issue. But in my case it was due to my branch's name. The branch's name automatically set in my GitHub repo as main instead of master.

git pull origin master (did not work).

I confirmed in GitHub if the name of the branch was actually master and found the the actual name was main. so the commands below worked for me. git pull origin main

To add a completely plain JavaScript solution that addressed @icedwater's issue with form submission, here's a complete solution with form.

NOTE: This is for "modern browsers", including IE9+. The IE8 version isn't much more complicated, and can be learned here.

Fiddle: https://jsfiddle.net/rufwork/gm6h25th/1/

HTML

<body>
    <form>
        <input type="text" id="txt" />
        <input type="button" id="go" value="Click Me!" />
        <div id="outige"></div>
    </form>
</body>

JavaScript

// The document.addEventListener replicates $(document).ready() for
// modern browsers (including IE9+), and is slightly more robust than `onload`.
// More here: https://stackoverflow.com/a/21814964/1028230
document.addEventListener("DOMContentLoaded", function() {
    var go = document.getElementById("go"),
        txt = document.getElementById("txt"),
        outige = document.getElementById("outige");

    // Note that jQuery handles "empty" selections "for free".
    // Since we're plain JavaScripting it, we need to make sure this DOM exists first.
    if (txt && go)    {
        txt.addEventListener("keypress", function (e) {
            if (event.keyCode === 13)   {
                go.click();
                e.preventDefault(); // <<< Most important missing piece from icedwater
            }
        });

        go.addEventListener("click", function () {
            if (outige) {
                outige.innerHTML += "Clicked!<br />";
            }
        });
    }
});

At first, you must specify your path, the path that your *.csv files are in there

path = 'f:\project\dataset'

You can change it based on your system.

then,

use dir function :

files = dir (strcat(path,'\*.csv'))

L = length (files);

for i=1:L
   image{i}=csvread(strcat(path,'\',file(i).name));   
   % process the image in here
end

pwd also can be used.

A possibility is to declare the variable at the index.html because it is really global. It can be done adding a javascript method to return the value of the variable, and it will be READ ONLY. I did like that:

Supposing that I have 2 global variables (var1 and var2). Just add to the index.html header this code:

  <script>
      function getVar1() {
          return 123;
      }
      function getVar2() {
          return 456;
      }
      function getGlobal(varName) {
          switch (varName) {
              case 'var1': return 123;
              case 'var2': return 456;
              // ...
              default: return 'unknown'
          }
      }
  </script>

It's possible to do a method for each variable or use one single method with a parameter.

This solution works between different vuejs mixins, it a really global value.

You can also set it in the [ServiceBehavior] tag above your class declaration that inherits the interface

[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
public class MyClass:IMyService
{
...
}

Immortal Blue is correct in not disclosing the exeption details to a publicly released version, but for testing purposes this is a handy tool. Always turn back off when releasing.

Child Component

Use this.$emit('event_name') to send an event to the parent component.

Parent Component

In order to listen to that event in the parent component, we do v-on:event_name and a method (ex. handleChange) that we want to execute on that event occurs

Done :)

Using docopt

Since 2012 there is a very easy, powerful and really cool module for argument parsing called docopt. Here is an example taken from its documentation:

"""Naval Fate.

Usage:
  naval_fate.py ship new <name>...
  naval_fate.py ship <name> move <x> <y> [--speed=<kn>]
  naval_fate.py ship shoot <x> <y>
  naval_fate.py mine (set|remove) <x> <y> [--moored | --drifting]
  naval_fate.py (-h | --help)
  naval_fate.py --version

Options:
  -h --help     Show this screen.
  --version     Show version.
  --speed=<kn>  Speed in knots [default: 10].
  --moored      Moored (anchored) mine.
  --drifting    Drifting mine.

"""
from docopt import docopt


if __name__ == '__main__':
    arguments = docopt(__doc__, version='Naval Fate 2.0')
    print(arguments)

So this is it: 2 lines of code plus your doc string which is essential and you get your arguments parsed and available in your arguments object.

Using python-fire

Since 2017 there's another cool module called python-fire. It can generate a CLI interface for your code with you doing zero argument parsing. Here's a simple example from the documentation (this small program exposes the function double to the command line):

import fire

class Calculator(object):

  def double(self, number):
    return 2 * number

if __name__ == '__main__':
  fire.Fire(Calculator)

From the command line, you can run:

> calculator.py double 10
20
> calculator.py double --number=15
30

If you are using Spring Boot, then add thymeleaf dependency into your pom.xml:

    <dependency>
        <groupId>org.thymeleaf</groupId>
        <artifactId>thymeleaf-spring4</artifactId>
        <version>2.1.6.RELEASE</version>
    </dependency>

You can use the description method inherited by NSDictionary from NSObject, or write a custom method that formats NSDictionary to your liking.

Following is the example code for how to use foreach in golang

package main

import (
    "fmt"
)

func main() {

    arrayOne := [3]string{"Apple", "Mango", "Banana"}

    for index,element := range arrayOne{

        fmt.Println(index)
        fmt.Println(element)        

    }   

}

This is a running example https://play.golang.org/p/LXptmH4X_0

For ASP.NET Core you'll need to spell it out:

@($"{Context.Request.Scheme}://{Context.Request.Host}{Context.Request.Path}{Context.Request.QueryString}")

Or you can add a using statement to your view:

@using Microsoft.AspNetCore.Http.Extensions

then

@Context.Request.GetDisplayUrl()

The _ViewImports.cshtml might be a better place for that @using

The best solution is not to use the same element for column and panel:

<div class="row">
    <div class="col-md-3">
        <div class="panel" id="gameplay-away-team">Away Team</div>
    </div>
    <div class="col-md-6">
        <div class="panel" id="gameplay-baseball-field">Baseball Field</div>
    </div>
    <div class="col-md-3">
        <div class="panel" id="gameplay-home-team">Home Team</div>
    </div>
</div>

and some more styles:

#gameplay-baseball-field {
  padding-right: 10px;
  padding-left: 10px;
}

You can try following sample http://jsfiddle.net/xKJB8/3/

<img id="preview" src="http://www.gravatar.com/avatar/0e39d18b89822d1d9871e0d1bc839d06?s=128&d=identicon&r=PG">
<canvas id="myCanvas" />

var c = document.getElementById("myCanvas");
var ctx = c.getContext("2d");
var img = document.getElementById("preview");
ctx.drawImage(img, 10, 10);
alert(c.toDataURL());

As far as I am concerned, I prefer to externalize the error messages in a properties files. This will be really helpful in case of internationalization of your application (one properties file per language). It is also easier to modify an error message, and it won't need any re-compilation of the Java sources.

On my projects, generally I have an interface that contains errors codes (String or integer, it doesn't care much), which contains the key in the properties files for this error:

public interface ErrorCodes {
    String DATABASE_ERROR = "DATABASE_ERROR";
    String DUPLICATE_USER = "DUPLICATE_USER";
    ...
}

in the properties file:

DATABASE_ERROR=An error occurred in the database.
DUPLICATE_USER=The user already exists.
...

Another problem with your solution is the maintenability: you have only 2 errors, and already 12 lines of code. So imagine your Enumeration file when you will have hundreds of errors to manage!

In case you want to use str() and a custom str method. This also works for repr.

class TypeProxy:
    def __init__(self, _type):
        self._type = _type

    def __call__(self, *args, **kwargs):
        return self._type(*args, **kwargs)

    def __str__(self):
        return self._type.__name__

    def __repr__(self):
        return "TypeProxy(%s)" % (repr(self._type),)

>>> str(TypeProxy(str))
'str'
>>> str(TypeProxy(type("")))
'str'

The following will parse an XML string into an XML document in all major browsers, including Internet Explorer 6. Once you have that, you can use the usual DOM traversal methods/properties such as childNodes and getElementsByTagName() to get the nodes you want.

var parseXml;
if (typeof window.DOMParser != "undefined") {
    parseXml = function(xmlStr) {
        return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
    };
} else if (typeof window.ActiveXObject != "undefined" &&
       new window.ActiveXObject("Microsoft.XMLDOM")) {
    parseXml = function(xmlStr) {
        var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async = "false";
        xmlDoc.loadXML(xmlStr);
        return xmlDoc;
    };
} else {
    throw new Error("No XML parser found");
}

Example usage:

var xml = parseXml("<foo>Stuff</foo>");
alert(xml.documentElement.nodeName);

Which I got from https://stackoverflow.com/a/8412989/1232175.

BIRT works pretty well.

Using String#gsub with regular expression:

"((String1))".gsub(/^\(+|\)+$/, '')
# => "String1"
"(((((( parentheses )))".gsub(/^\(+|\)+$/, '')
# => " parentheses "

This will remove surrounding parentheses only.

"(((((( This (is) string )))".gsub(/^\(+|\)+$/, '')
# => " This (is) string "
