The package hash is now available: https://cran.r-project.org/web/packages/hash/hash.pdf

Examples

h <- hash( keys=letters, values=1:26 )
h <- hash( letters, 1:26 )
h$a
# [1] 1
h$foo <- "bar"
h[ "foo" ]
# <hash> containing 1 key-value pair(s).
#   foo : bar
h[[ "foo" ]]
# [1] "bar"

I had this problem and the issue was that I had the package loaded in another R instance. Simply closing all R instances and installing on a fresh instance allowed for the package to be installed.

Generally, you can also install if every remaining instance has never loaded the package as well (even if it installed an old version).

I think you should use null

SELECT CustomerName AS Customer, null AS Contact 
FROM Customers;

And Remember that Oracle

treats a character value with a length of zero as null.

If you give the following command you'll get the list of activities including commits, merges.

git reflog

Your last commit should probably be at 'HEAD@{0}'. You can check the same with your commit message. To go to that point, use the command

git reset --hard 'HEAD@{0}'

Your merge will be reverted. If in case you have new files left, discard those changes from the merge.

You say you've had problems with Navicat. For the record, I use Navicat and I haven't experienced the issue you describe. You might want to dig around, see if there's a reason for your problem and/or a solution, because given the question asked, my first recommendation would have been Navicat.

But if you want alternative suggestions, here are a few that I know of and have used:

MySQL has its own tool which you can download for free, called MySQL Workbench. Download it from here: http://wb.mysql.com/. My experience is that it's powerful, but I didn't really like the UI. But that's just my personal taste.

Another free program you might want to try is HeidiSQL. It's more similar to Navicat than MySQL Workbench. A colleague of mine loves it.

(interesting to note, by the way, that MariaDB (the forked version of MySQL) is currently shipped with HeidiSQL as its GUI tool)

Finally, if you're running a web server on your machine, there's always the option of a browser-based tool like PHPMyAdmin. It's actually a surprisingly powerful piece of software.

In matplotlib 2.0 there is a parameter called fillstyle which allows better control on the way markers are filled. In my case I have used it with errorbars but it works for markers in general http://matplotlib.org/api/_as_gen/matplotlib.axes.Axes.errorbar.html

fillstyle accepts the following values: [‘full’ | ‘left’ | ‘right’ | ‘bottom’ | ‘top’ | ‘none’]

There are two important things to keep in mind when using fillstyle,

1) If mfc is set to any kind of value it will take priority, hence, if you did set fillstyle to 'none' it would not take effect. So avoid using mfc in conjuntion with fillstyle

2) You might want to control the marker edge width (using markeredgewidth or mew) because if the marker is relatively small and the edge width is thick, the markers will look like filled even though they are not.

Following is an example using errorbars:

myplot.errorbar(x=myXval, y=myYval, yerr=myYerrVal, fmt='o', fillstyle='none', ecolor='blue',  mec='blue')

What it does

Maven is a "build management tool", it is for defining how your .java files get compiled to .class, packaged into .jar (or .war or .ear) files, (pre/post)processed with tools, managing your CLASSPATH, and all others sorts of tasks that are required to build your project. It is similar to Apache Ant or Gradle or Makefiles in C/C++, but it attempts to be completely self-contained in it that you shouldn't need any additional tools or scripts by incorporating other common tasks like downloading & installing necessary libraries etc.

It is also designed around the "build portability" theme, so that you don't get issues as having the same code with the same buildscript working on one computer but not on another one (this is a known issue, we have VMs of Windows 98 machines since we couldn't get some of our Delphi applications compiling anywhere else). Because of this, it is also the best way to work on a project between people who use different IDEs since IDE-generated Ant scripts are hard to import into other IDEs, but all IDEs nowadays understand and support Maven (IntelliJ, Eclipse, and NetBeans). Even if you don't end up liking Maven, it ends up being the point of reference for all other modern builds tools.

Why you should use it

There are three things about Maven that are very nice.

1. Maven will (after you declare which ones you are using) download all the libraries that you use and the libraries that they use for you automatically. This is very nice, and makes dealing with lots of libraries ridiculously easy. This lets you avoid "dependency hell". It is similar to Apache Ant's Ivy.

2. It uses "Convention over Configuration" so that by default you don't need to define the tasks you want to do. You don't need to write a "compile", "test", "package", or "clean" step like you would have to do in Ant or a Makefile. Just put the files in the places in which Maven expects them and it should work off of the bat.

3. Maven also has lots of nice plug-ins that you can install that will handle many routine tasks from generating Java classes from an XSD schema using JAXB to measuring test coverage with Cobertura. Just add them to your pom.xml and they will integrate with everything else you want to do.

The initial learning curve is steep, but (nearly) every professional Java developer uses Maven or wishes they did. You should use Maven on every project although don't be surprised if it takes you a while to get used to it and that sometimes you wish you could just do things manually, since learning something new sometimes hurts. However, once you truly get used to Maven you will find that build management takes almost no time at all.

How to Start

The best place to start is "Maven in 5 Minutes". It will get you start with a project ready for you to code in with all the necessary files and folders set-up (yes, I recommend using the quickstart archetype, at least at first).

After you get started you'll want a better understanding over how the tool is intended to be used. For that "Better Builds with Maven" is the most thorough place to understand the guts of how it works, however, "Maven: The Complete Reference" is more up-to-date. Read the first one for understanding, but then use the second one for reference.

we can use different types of system fonts like below

myButton.titleLabel?.font = UIFont.boldSystemFont(ofSize: 17)
myButton.titleLabel?.font = UIFont.italicSystemFont(ofSize:UIFont.smallSystemFontSize)
myButton.titleLabel?.font = UIFont.boldSystemFont(ofSize: UIFont.buttonFontSize)

and your custom font like below

    myButton.titleLabel?.font = UIFont(name: "Helvetica", size:12)

Add permission [Domain Users] to your web security.

• Right click on your site in IIS under the Sites folder
• Click Edit Permissions...
• Select the Security tab
• Under the Group or usernames section click the Edit... button
• In the Permissions pop up, under the Group or user names click Add...
• Enter [Domain Users] in the object names to select text area and click OK to apply the change
• Click OK to close the Permissions pop up
• Click OK to close the Properties pop up and apply your new settings

If an Activity calls onPause with a normal broadcast, receiving the Broadcast can be missed. A sticky broadcast can be checked after it was initiated in onResume.

Update 6/23/2020

Sticky broadcasts are deprecated.

See sendStickyBroadcast documentation.

This method was deprecated in API level 21.

Sticky broadcasts should not be used. They provide no security (anyone can access them), no protection (anyone can modify them), and many other problems. The recommended pattern is to use a non-sticky broadcast to report that something has changed, with another mechanism for apps to retrieve the current value whenever desired.

Implement

Intent intent = new Intent("some.custom.action");
intent.putExtra("some_boolean", true);
sendStickyBroadcast(intent);

• Related post: What is the difference between sendStickyBroadcast and sendBroadcast in Android?

• See removeStickyBroadcast(Intent), and on API Level 5 +, isInitialStickyBroadcast() for usage in the Receiver's onReceive.

I solved this,

1) by creating new commit with changes i want..

r8gs4r commit 0

2) i know which commit i need to merge with it. which is commit 3.

so, git rebase -i HEAD~4 # 4 represents recent 4 commit (here commit 3 is in 4th place)

3) in interactive rebase recent commit will located at bottom. it will looks alike,

pick q6ade6 commit 3
pick vr43de commit 2
pick ac123d commit 1
pick r8gs4r commit 0

4) here we need to rearrange commit if you want to merge with specific one. it should be like,

parent
|_child

pick q6ade6 commit 3
f r8gs4r commit 0
pick vr43de commit 2
pick ac123d commit 1

after rearrange you need to replace p pick with f (fixup will merge without commit message) or s (squash merge with commit message can change in run time)

and then save your tree.

now merge done with existing commit.

Note: Its not preferable method unless you're maintain on your own. if you have big team size its not a acceptable method to rewrite git tree will end up in conflicts which you know other wont. if you want to maintain you tree clean with less commits can try this and if its small team otherwise its not preferable.....

Tagging of the image isn't supported inside the Dockerfile. This needs to be done in your build command. As a workaround, you can do the build with a docker-compose.yml that identifies the target image name and then run a docker-compose build. A sample docker-compose.yml would look like

version: '2'

services:
  man:
    build: .
    image: dude/man:v2

That said, there's a push against doing the build with compose since that doesn't work with swarm mode deploys. So you're back to running the command as you've given in your question:

docker build -t dude/man:v2 .

Personally, I tend to build with a small shell script in my folder (build.sh) which passes any args and includes the name of the image there to save typing. And for production, the build is handled by a ci/cd server that has the image name inside the pipeline script.

I had a similar issue when deploying from OSx on my local to my Linux live site.

It ran fine on OSx, but on Linux I was getting:

An Error Was Encountered

Unable to load the requested class: Ckeditor

The problem was that Linux paths are apparently case-sensitive so I had to rename my library files from "ckeditor.php" to "CKEditor.php".

I also changed my load call to match the capitalization:

$this->load->library('CKEditor');

If you've got ther JSON data coming in as a string (e.g. '[{"id":1,"name":"Charles"},{"id":8,"name":"John"},{"id":13,"name":"Sally"}]')

Then I'd use JSON.net and use Linq to JSON to get the values out...

    {
        var items = Request["items"].ToString(); // Get the JSON string
        JArray o = JArray.Parse(items); // It is an array so parse into a JArray
        var a = o.SelectToken("[0].name").ToString(); // Get the name value of the 1st object in the array
        // a == "Charles"
    }
}
}

Simply compare the last n characters using std::string::compare:

#include <iostream>

bool hasEnding (std::string const &fullString, std::string const &ending) {
    if (fullString.length() >= ending.length()) {
        return (0 == fullString.compare (fullString.length() - ending.length(), ending.length(), ending));
    } else {
        return false;
    }
}

int main () {
    std::string test1 = "binary";
    std::string test2 = "unary";
    std::string test3 = "tertiary";
    std::string test4 = "ry";
    std::string ending = "nary";

    std::cout << hasEnding (test1, ending) << std::endl;
    std::cout << hasEnding (test2, ending) << std::endl;
    std::cout << hasEnding (test3, ending) << std::endl;
    std::cout << hasEnding (test4, ending) << std::endl;

    return 0;
}

There seems to be a syntactically simpler way, and therefore easier to remember, as opposed to the proposed solutions. I'm assuming that the column is called 'meta' in a dataframe df:

df2 = pd.DataFrame(df['meta'].str.split().values.tolist())

Change

 mAdapter = new RecordingsListAdapter(this, recordings);

to

 mAdapter = new RecordingsListAdapter(getActivity(), recordings);

and also make sure that recordings!=null at mAdapter = new RecordingsListAdapter(this, recordings);

I tested this command:

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings
adb shell input keyevent 19 && adb shell input keyevent 19 && adb shell input keyevent 23

and only works on window's prompt, maybe because of some driver

The adb shell svc wifi enable|disable solution only works with root permissions.

to convert to lower case is equivalent to rise bit 0x60 if you restrict yourself to ASCII:

for(char *p = pstr; *p; ++p)
    *p = *p > 0x40 && *p < 0x5b ? *p | 0x60 : *p;

Just an update.

Now if it's a github repository then using just a github shorthand is enough if you do not mind the version of course.

GitHub shorthand

$ bower install desandro/masonry

days, years, etc., are part of Active Support, So this won't work in irb, but it should work in rails console.

You can also be interested at the top answer in here: https://askubuntu.com/questions/1080204/gpg-problem-with-the-agent-permission-denied

basically the solution that worked for me too is:

gpg --decrypt --pinentry-mode=loopback <file>

Reflection e.g.:

public class PrivateObject {

  private String privateString = null;

  public PrivateObject(String privateString) {
    this.privateString = privateString;
  }
}
PrivateObject privateObject = new PrivateObject("The Private Value");

Field privateStringField = PrivateObject.class.
            getDeclaredField("privateString");

privateStringField.setAccessible(true);

String fieldValue = (String) privateStringField.get(privateObject);
System.out.println("fieldValue = " + fieldValue);

Given that the Apache Subversion server will be moved to this new DNS alias: sub.someaddress.com.tr:

• With Subversion 1.7 or higher, use svn relocate. Relocate is used when the SVN server's location changes. switch is only used if you want to change your local working copy to another branch or another path. If using TortoiseSVN, you may follow instructions from the TortoiseSVN Manual. If using the SVN command line interface, refer to this section of SVN's documentation. The command should look like this:

  svn relocate svn://sub.someaddress.com.tr/project

• Keep using /project given that the actual contents of your repository probably won't change.

Note: svn relocate is not available before version 1.7 (thanks to ColinM for the info). In older versions you would use:

    svn switch --relocate OLD NEW

You're offsetting the shadow, so to get it to uniformly surround the box, don't offset it:

-moz-box-shadow: 0 0 3px #ccc;
-webkit-box-shadow: 0 0 3px #ccc;
box-shadow: 0 0 3px #ccc;

When I try to set Base Memory around 4000MB (my pc have 8GB) I get the same error 'VT-x is disabled in the BIOS'. But when I reduce Base Memory to 2500MB it works and error is solved.

Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

Remote update

You need to run

git remote update

or

git remote update <remote> 

Then you can run git branch -r to list the remote branches.

Checkout a new branch

To track a (new) remote branch as a local branch:

git checkout -b <local branch> <remote>/<remote branch>

or (sometimes it doesn't work without the extra remotes/):

git checkout -b <local branch> remotes/<remote>/<remote branch>

In Android Oreo and above version we have to approach different methods to install apk programatically.

 private void installApkProgramatically() {


    try {
        File path = activity.getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS);

        File file = new File(path, filename);

        Uri uri;

        if (file.exists()) {

            Intent unKnownSourceIntent = new Intent(Settings.ACTION_MANAGE_UNKNOWN_APP_SOURCES).setData(Uri.parse(String.format("package:%s", activity.getPackageName())));

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

                if (!activity.getPackageManager().canRequestPackageInstalls()) {
                    startActivityForResult(unKnownSourceIntent, Constant.UNKNOWN_RESOURCE_INTENT_REQUEST_CODE);
                } else {
                    Uri fileUri = FileProvider.getUriForFile(activity.getBaseContext(), activity.getApplicationContext().getPackageName() + ".provider", file);
                    Intent intent = new Intent(Intent.ACTION_VIEW, fileUri);
                    intent.putExtra(Intent.EXTRA_NOT_UNKNOWN_SOURCE, true);
                    intent.setDataAndType(fileUri, "application/vnd.android" + ".package-archive");
                    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
                    intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                    startActivity(intent);
                    alertDialog.dismiss();
                }

            } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {

                Intent intent1 = new Intent(Intent.ACTION_INSTALL_PACKAGE);
                uri = FileProvider.getUriForFile(activity.getApplicationContext(), BuildConfig.APPLICATION_ID + ".provider", file);

                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(intent);
            }
        } else {

            Log.i(TAG, " file " + file.getPath() + " does not exist");
        }
    } catch (Exception e) {

        Log.i(TAG, "" + e.getMessage());

In Oreo and above version we need unknown resource installation permission. so in activity result u have to check the result for the permission

    @Override
public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {

        case Constant.UNKNOWN_RESOURCE_INTENT_REQUEST_CODE:
            switch (resultCode) {
                case Activity.RESULT_OK:
                    installApkProgramatically();

                    break;
                case Activity.RESULT_CANCELED:
                    //unknown resouce installation cancelled

                    break;
            }
            break;
    }
}

Try this:

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.net.URL;
import javax.imageio.ImageIO;

public class WriteImage 
{   
    public static void main( String[] args )
    {
        BufferedImage image = null;
        try {

            URL url = new URL("URL_IMAGE");
            image = ImageIO.read(url);

            ImageIO.write(image, "jpg",new File("C:\\out.jpg"));
            ImageIO.write(image, "gif",new File("C:\\out.gif"));
            ImageIO.write(image, "png",new File("C:\\out.png"));

        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println("Done");
    }
}

Use colSds function from matrixStats library.

library(matrixStats)
set.seed(42)
M <- matrix(rnorm(40),ncol=4)
colSds(M)

[1] 0.8354488 1.6305844 1.1560580 1.1152688

If settings.functionName is already a function, you could do this:

settings.functionName(t.parentNode.id);

Otherwise this should also work if settings.functionName is just the name of the function:

if (typeof window[settings.functionName] == "function") {
    window[settings.functionName](t.parentNode.id);
}

This seems like the easiest (but not most robust) way to me. Simply compute the sum from row 6 to the maximum allowed row number, as specified by Excel. According to this site, the maximum is currently 1048576, so the following should work for you:

=sum(c6:c1048576)

For more robust solutions, see the other answers.

To change the actual local market:

Basically the market is determined automatically based on your IP. You can change some local country settings from your Gmail account settings but still IP of the country you're browsing from is more important. To go around it you'd have to Proxy-cheat.

In one of my application i need to take picture either from Camera/Gallery. If user click image from Camera(may be 2MP, 5MP or 8MP), image size varies from kBs to MBs. If image size is less(or up to 1-2MB) above code working fine but if i have image of size above 4MB or 5MB then OOM comes in frame :(

then i have worked to solve this issue & finally i've made the below improvement to Fedor's(All Credit to Fedor for making such a nice solution) code :)

    BitmapFactory.decodeFile(fPath, opts);

    // The new size we want to scale to
    final int REQUIRED_SIZE = 70;

    // Find the correct scale value. 
    int scale = 1;

    if (opts.outHeight > REQUIRED_SIZE || opts.outWidth > REQUIRED_SIZE) {

        // Calculate ratios of height and width to requested height and width
        final int heightRatio = Math.round((float) opts.outHeight
                / (float) REQUIRED_SIZE);
        final int widthRatio = Math.round((float) opts.outWidth
                / (float) REQUIRED_SIZE);

        // Choose the smallest ratio as inSampleSize value, this will guarantee
        // a final image with both dimensions larger than or equal to the
        // requested height and width.
        scale = heightRatio < widthRatio ? heightRatio : widthRatio;//
    }

    // Decode bitmap with inSampleSize set
    opts.inJustDecodeBounds = false;

    opts.inSampleSize = scale;

    Bitmap bm = BitmapFactory.decodeFile(fPath, opts).copy(
            Bitmap.Config.RGB_565, false);

    return bm;

For me, works adding this configuration in the gradle.properties file of the project, where the build.gradle file is:

systemProp.http.proxyHost=proxyURL
systemProp.http.proxyPort=proxyPort
systemProp.http.proxyUser=USER
systemProp.http.proxyPassword=PASSWORD
systemProp.https.proxyHost=proxyUrl 
systemProp.https.proxyPort=proxyPort
systemProp.https.proxyUser=USER
systemProp.https.proxyPassword=PASSWORD

Where : proxyUrl is the url of the proxy server (http://.....)

proxyPort is the port (usually 8080)

USER is my domain user

PASSWORD, my password

In this case, the proxy for http and https is the same

Adding my specific problem/solution to this as this is the first result for this error message. In my case, the error was received when I deployed a second application within the folder of my first application in IIS. Both were defining connection string with the same name resulting in the child application having a conflict and in turn generating this (to me) non-obvious error message. It was solved by adding:

<clear/>

in the connection string block of the child web application which prevented it from inheriting the connection strings of web.config files higher in the hierarchy, so it looks like:

<connectionStrings>
  <clear/>
  <add name="DbContext" connectionString="MySERVER" providerName="System.Data.SqlClient" />
</connectionStrings>

A reference Stack Overflow question which helped once I determined what was going on was Will a child application inherit from its parent web.config?.

public static void main(String[] args) 
{
    Date d = new Date();
    SimpleDateFormat form = new SimpleDateFormat("dd-mm-yyyy hh:mm:ss");
    System.out.println(form.format(d));
    String str = form.format(d); // or if you want to save it in String str
    System.out.println(str); // and print after that
}

getApplicationContext() - Returns the context for all activities running in application.

getBaseContext() - If you want to access Context from another context within application you can access.

getContext() - Returns the context view only current running activity.

In curl request add time out 0 so its infinite time set like CURLOPT_TIMEOUT set 0

Alternatively, consider The Glass Pane, discussed in the article How to Use Root Panes. You could draw your "Feature" content in the glass pane's paintComponent() method.

Addendum: Working with the GlassPaneDemo, I added an image:

//Set up the content pane, where the "main GUI" lives.
frame.add(changeButton, BorderLayout.SOUTH);
frame.add(new JLabel(new ImageIcon("img.jpg")), BorderLayout.CENTER);

and altered the glass pane's paintComponent() method:

protected void paintComponent(Graphics g) {
    if (point != null) {
        Graphics2D g2d = (Graphics2D) g;
        g2d.setRenderingHint(
            RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);
        g2d.setComposite(AlphaComposite.getInstance(
            AlphaComposite.SRC_OVER, 0.3f));
        g2d.setColor(Color.yellow);
        g2d.fillOval(point.x, point.y, 120, 60);
    }
}

As noted here, Swing components must honor the opaque property; in this variation, the ImageIcon completely fills the BorderLayout.CENTER of the frame's default layout.

Have a look at ?"%in%".

dt[dt$fct %in% vc,]
   fct X
1    a 2
3    c 3
5    c 5
7    a 7
9    c 9
10   a 1
12   c 2
14   c 4

You could also use ?is.element:

dt[is.element(dt$fct, vc),]

You can't do this with plain vanilla HTML, so JSF can't do much for you here as well.

If you're targeting decent browsers only, then just make use of CSS3:

.unselectable {
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

<label class="unselectable">Unselectable label</label>

If you'd like to cover older browsers as well, then consider this JavaScript fallback:

<!doctype html>
<html lang="en">
    <head>
        <title>SO question 2310734</title>
        <script>
            window.onload = function() {
                var labels = document.getElementsByTagName('label');
                for (var i = 0; i < labels.length; i++) {
                    disableSelection(labels[i]);
                }
            };
            function disableSelection(element) {
                if (typeof element.onselectstart != 'undefined') {
                    element.onselectstart = function() { return false; };
                } else if (typeof element.style.MozUserSelect != 'undefined') {
                    element.style.MozUserSelect = 'none';
                } else {
                    element.onmousedown = function() { return false; };
                }
            }
        </script>
    </head>
    <body>
        <label>Try to select this</label>
    </body>
</html>

If you're already using jQuery, then here's another example which adds a new function disableSelection() to jQuery so that you can use it anywhere in your jQuery code:

<!doctype html>
<html lang="en">
    <head>
        <title>SO question 2310734 with jQuery</title>
        <script src="http://code.jquery.com/jquery-latest.min.js"></script>
        <script>
            $.fn.extend({ 
                disableSelection: function() { 
                    this.each(function() { 
                        if (typeof this.onselectstart != 'undefined') {
                            this.onselectstart = function() { return false; };
                        } else if (typeof this.style.MozUserSelect != 'undefined') {
                            this.style.MozUserSelect = 'none';
                        } else {
                            this.onmousedown = function() { return false; };
                        }
                    }); 
                } 
            });

            $(document).ready(function() {
                $('label').disableSelection();            
            });
        </script>
    </head>
    <body>
        <label>Try to select this</label>
    </body>
</html>

I was receiving this error because I happened to be opening a website project over a mapped network drive z:\folder instead of connecting via a UNC path \\server\path\folder. Once I opened the project from the UNC path it built just fine.

You can't define width/height/margins/... using percents in your XML. But what you would want to use is the "weight" attribute, which is, IMO, the most similar thing.

Another method would be to set the sizes programmatically after you inflate the layout in your code, by getting the size of your screen and calculating needed margins.

For the record, you can use POSIX standard exit codes defined here.

Example:

import sys, os

try:
    config()
except:
    sys.exit(os.EX_CONFIG) 
try:
    do_stuff()
except:
    sys.exit(os.EX_SOFTWARE)
sys.exit(os.EX_OK) # code 0, all ok

I don't understand what the meaning of ordering with the same column ASC and DESC in the same ORDER BY, but this how you can do it: naam DESC, naam ASC like so:

ORDER BY `product_category_id` DESC,`naam` DESC, `naam` ASC

You could maybe disable and re-enable constraints:

You may have a try for https://github.com/cls1991/pef. It will remove package with its all dependencies.

Go to File -> Project Structure. Following window will open:

From there:

1. remove the junit library (select junit and press "-" button below ) and
2. add it again (select "+" button below, select "library dep.", search for "junit", press OK ). Press OK to apply changes. After around 30 seconds your gradle sync should work fine.

Hope it works for you too :D

you can use CHARINDEX in t-sql.

select * from table where CHARINDEX(url, 'http://url.com/url?url...') > 0

Use event delegation by assigning the onclick to the <ol>. Then pass the event object as the argument, and using that, grab the text from the clicked element.

function addText(event) {_x000D_
    var targ = event.target || event.srcElement;_x000D_
    document.getElementById("alltext").value += targ.textContent || targ.innerText;_x000D_
}

<textarea id="alltext"></textarea>_x000D_
_x000D_
<ol onclick="addText(event)">_x000D_
  <li>Hello</li>_x000D_
  <li>World</li>_x000D_
  <li>Earthlings</li>_x000D_
</ol>

Note that this method of passing the event object works in older IE as well as W3 compliant systems.

What you need to do is create a new input field, append it to the body, focus it and the hide it using display:none. You will need to enclose these inside some setTimeouts unfortunately to make this work.

var field = document.createElement('input');
field.setAttribute('type', 'text');
document.body.appendChild(field);

setTimeout(function() {
    field.focus();
    setTimeout(function() {
        field.setAttribute('style', 'display:none;');
    }, 50);
}, 50);

• Kotlin Version via Extension Function

To find a resource id by its name In Kotlin, add below snippet in a kotlin file:

ExtensionFunctions.kt

import android.content.Context
import android.content.res.Resources

fun Context.resIdByName(resIdName: String?, resType: String): Int {
    resIdName?.let {
        return resources.getIdentifier(it, resType, packageName)
    }
    throw Resources.NotFoundException()
}

• Usage

Now all resource ids are accessible wherever you have a context reference using resIdByName method:

val drawableResId = context.resIdByName("ic_edit_black_24dp", "drawable")
val stringResId = context.resIdByName("title_home", "string")
.
.
.    

I think you are looking for below method:

var idList=new int[]{1, 2, 3, 4};
using (var db=new SomeDatabaseContext())
{
    var friends= db.Friends.Where(f=>idList.Contains(f.ID));
    friends.ForEachAsync(a=>a.msgSentBy='1234');
    await db.SaveChangesAsync();
}

This should be the efficient way of handling this.

Use the validators package:

>>> import validators
>>> validators.url("http://google.com")
True
>>> validators.url("http://google")
ValidationFailure(func=url, args={'value': 'http://google', 'require_tld': True})
>>> if not validators.url("http://google"):
...     print "not valid"
... 
not valid
>>>

Install it from PyPI with pip (pip install validators).

Linting is the process of running a program that will analyse code for potential errors.

See lint on wikipedia:

lint was the name originally given to a particular program that flagged some suspicious and non-portable constructs (likely to be bugs) in C language source code. The term is now applied generically to tools that flag suspicious usage in software written in any computer language.

For deep cloning (clones the entire object hierarchy):

• commons-lang SerializationUtils - using serialization - if all classes are in your control and you can force implementing Serializable.

• Java Deep Cloning Library - using reflection - in cases when the classes or the objects you want to clone are out of your control (a 3rd party library) and you can't make them implement Serializable, or in cases you don't want to implement Serializable.

For shallow cloning (clones only the first level properties):

• commons-beanutils BeanUtils - in most cases.

• Spring BeanUtils - if you are already using spring and hence have this utility on the classpath.

I deliberately omitted the "do-it-yourself" option - the API's above provide a good control over what to and what not to clone (for example using transient, or String[] ignoreProperties), so reinventing the wheel isn't preferred.

JDK 9 has added InputStream#transferTo(OutputStream out) for this functionality.

I'm using python 3.4, requests 2.19.1:

'urllib3' is the logger to get now (no longer 'requests.packages.urllib3'). Basic logging will still happen without setting http.client.HTTPConnection.debuglevel

apt-get install libjpeg-dev
apt-get install libfreetype6-dev
apt-get install zlib1g-dev
apt-get install libpng12-dev

Install these and be sure to install PIL with pip because I compiled it from source and for some reason it didn't work

Alter table table_name modify column_name datatype(length) AUTO_INCREMENT PRIMARY KEY

You should add primary key to auto increment, otherwise you got error in mysql.

First, remove all files from your Git repository using: git rm -r *

After that you should commit: using git commit -m "your comment"

After that you push using: git push (that's update the origin repository)

To verify your status using: git status

After that you can copy all your local files in the local Git folder, and you add them to the Git repository using: git add -A

You commit (git commit -m "your comment" and you push (git push)

With bootstrap4 you can easily do it like this :-

class="rounded" 

or

class="rounded-circle"

When adding a new column ("initialize a new field") and setting a single value to each existing row, I use the following tactic:

ALTER TABLE MyTable
 add NewColumn  int  not null
  constraint MyTable_TemporaryDefault
   default -1

ALTER TABLE MyTable
 drop constraint MyTable_TemporaryDefault

If the column is nullable and you don't include a "declared" constraint, the column will be set to null for all rows.

According To Apple you don't need an import for swift files in the Same Target. I finally got it working by adding my swift file to both my regular target and test target. Then I used the bridging header for test to make sure my ObjC files that I referenced in my regular bridging header were available. Ran like a charm now.

import XCTest
//Optionally you can import the whole Objc Module by doing #import ModuleName

class HHASettings_Tests: XCTestCase {

override func setUp() {
    let x : SettingsTableViewController = SettingsTableViewController()

    super.setUp()
    // Put setup code here. This method is called before the invocation of each test method in the class.
}

override func tearDown() {
    // Put teardown code here. This method is called after the invocation of each test method in the class.
    super.tearDown()
}

func testExample() {
    // This is an example of a functional test case.
    XCTAssert(true, "Pass")
}

func testPerformanceExample() {
    // This is an example of a performance test case.
    self.measureBlock() {
        // Put the code you want to measure the time of here.
    }
}

}

SO make sure PrimeNumberModel has a target of your test Target. Or High6 solution of importing your whole module will work

Instead of using the outrageously convoluted data structures required by ggplot2, you can use the native R functions:

tab<-read.delim(text="
Company 2011 2013
Company1 300 350
Company2 320 430
Company3 310 420
",as.is=TRUE,sep=" ",row.names=1)

tab<-t(tab)

plot(tab[,1],type="b",ylim=c(min(tab),max(tab)),col="red",lty=1,ylab="Value",lwd=2,xlab="Year",xaxt="n")
lines(tab[,2],type="b",col="black",lty=2,lwd=2)
lines(tab[,3],type="b",col="blue",lty=3,lwd=2)
grid()
legend("topleft",legend=colnames(tab),lty=c(1,2,3),col=c("red","black","blue"),bg="white",lwd=2)
axis(1,at=c(1:nrow(tab)),labels=rownames(tab))

Update: This supports only with UWP - Windows Community Toolkit

There is a much easier way now. You can use the RssParser class. The sample code is given below.

public async void ParseRSS()
{
    string feed = null;

    using (var client = new HttpClient())
    {
        try
        {
            feed = await client.GetStringAsync("https://visualstudiomagazine.com/rss-feeds/news.aspx");
        }
        catch { }
    }

    if (feed != null)
    {
        var parser = new RssParser();
        var rss = parser.Parse(feed);

        foreach (var element in rss)
        {
            Console.WriteLine($"Title: {element.Title}");
            Console.WriteLine($"Summary: {element.Summary}");
        }
    }
}

For non-UWP use the Syndication from the namespace System.ServiceModel.Syndication as others suggested.

public static IEnumerable <FeedItem> GetLatestFivePosts() {
    var reader = XmlReader.Create("https://sibeeshpassion.com/feed/");
    var feed = SyndicationFeed.Load(reader);
    reader.Close();
    return (from itm in feed.Items select new FeedItem {
        Title = itm.Title.Text, Link = itm.Id
    }).ToList().Take(5);
}

public class FeedItem {
    public string Title {
        get;
        set;
    }
    public string Link {
        get;
        set;
    }
}

Imagine having this hierarchy

1. Extends

By writing

    List<? extends C2> list;

you are saying that list will be able to reference an object of type (for example) ArrayList whose generic type is one of the 7 subtypes of C2 (C2 included):

1. C2: new ArrayList<C2>();, (an object that can store C2 or subtypes) or
2. D1: new ArrayList<D1>();, (an object that can store D1 or subtypes) or
3. D2: new ArrayList<D2>();, (an object that can store D2 or subtypes) or...

and so on. Seven different cases:

    1) new ArrayList<C2>(): can store C2 D1 D2 E1 E2 E3 E4
    2) new ArrayList<D1>(): can store    D1    E1 E2  
    3) new ArrayList<D2>(): can store       D2       E3 E4
    4) new ArrayList<E1>(): can store          E1             
    5) new ArrayList<E2>(): can store             E2             
    6) new ArrayList<E3>(): can store                E3             
    7) new ArrayList<E4>(): can store                   E4             

We have a set of "storable" types for each possible case: 7 (red) sets here graphically represented

As you can see, there is not a safe type that is common to every case:

• you cannot list.add(new C2(){}); because it could be list = new ArrayList<D1>();
• you cannot list.add(new D1(){}); because it could be list = new ArrayList<D2>();

and so on.

2. Super

By writing

    List<? super C2> list;

you are saying that list will be able to reference an object of type (for example) ArrayList whose generic type is one of the 7 supertypes of C2 (C2 included):

• A1: new ArrayList<A1>();, (an object that can store A1 or subtypes) or
• A2: new ArrayList<A2>();, (an object that can store A2 or subtypes) or
• A3: new ArrayList<A3>();, (an object that can store A3 or subtypes) or...

and so on. Seven different cases:

    1) new ArrayList<A1>(): can store A1          B1 B2       C1 C2    D1 D2 E1 E2 E3 E4
    2) new ArrayList<A2>(): can store    A2          B2       C1 C2    D1 D2 E1 E2 E3 E4
    3) new ArrayList<A3>(): can store       A3          B3       C2 C3 D1 D2 E1 E2 E3 E4
    4) new ArrayList<A4>(): can store          A4       B3 B4    C2 C3 D1 D2 E1 E2 E3 E4
    5) new ArrayList<B2>(): can store                B2       C1 C2    D1 D2 E1 E2 E3 E4
    6) new ArrayList<B3>(): can store                   B3       C2 C3 D1 D2 E1 E2 E3 E4
    7) new ArrayList<C2>(): can store                            C2    D1 D2 E1 E2 E3 E4

We have a set of "storable" types for each possible case: 7 (red) sets here graphically represented

As you can see, here we have seven safe types that are common to every case: C2, D1, D2, E1, E2, E3, E4.

• you can list.add(new C2(){}); because, regardless of the kind of List we're referencing, C2 is allowed
• you can list.add(new D1(){}); because, regardless of the kind of List we're referencing, D1 is allowed

and so on. You probably noticed that these types correspond to the hierarchy starting from type C2.

Notes

Here the complete hierarchy if you wish to make some tests

interface A1{}
interface A2{}
interface A3{}
interface A4{}

interface B1 extends A1{}
interface B2 extends A1,A2{}
interface B3 extends A3,A4{}
interface B4 extends A4{}

interface C1 extends B2{}
interface C2 extends B2,B3{}
interface C3 extends B3{}

interface D1 extends C1,C2{}
interface D2 extends C2{}

interface E1 extends D1{}
interface E2 extends D1{}
interface E3 extends D2{}
interface E4 extends D2{}

I tried all of the above solutions and it still wouldn't work, until I found that the web.config compilation element was referencing version 2.0.0.0 of WebMatrix.Data and WebMatrix.WebData. Changing the version of those entries in the web.config to 3.0.0.0 helped me.

In Git, to "fast forward" means to update the HEAD pointer in such a way that its new value is a direct descendant of the prior value. In other words, the prior value is a parent, or grandparent, or grandgrandparent, ...

Fast forwarding is not possible when the new HEAD is in a diverged state relative to the stream you want to integrate. For instance, you are on master and have local commits, and git fetch has brought new upstream commits into origin/master. The branch now diverges from its upstream and cannot be fast forwarded: your master HEAD commit is not an ancestor of origin/master HEAD. To simply reset master to the value of origin/master would discard your local commits. The situation requires a rebase or merge.

If your local master has no changes, then it can be fast-forwarded: simply updated to point to the same commit as the latestorigin/master. Usually, no special steps are needed to do fast-forwarding; it is done by merge or rebase in the situation when there are no local commits.

Is it ok to assume that fast-forward means all commits are replayed on the target branch and the HEAD is set to the last commit on that branch?

No, that is called rebasing, of which fast-forwarding is a special case when there are no commits to be replayed (and the target branch has new commits, and the history of the target branch has not been rewritten, so that all the commits on the target branch have the current one as their ancestor.)

Check whether your phone supports the video format or not.Even I had the problem when playing a 3gp file but it played a mp4 file perfectly.

Full example in pure JavaScript :

box.onmouseup = function() {_x000D_
  var temp = this.children[0];_x000D_
  if (temp.checked) {_x000D_
    setTimeout(function() {_x000D_
      temp.checked = false;_x000D_
    }, 0);_x000D_
  }_x000D_
}

<label id='box' style='margin-right: 1em;'>_x000D_
  <input type='radio' name='chk_préf_méd_perso' value='valeur'>_x000D_
  libellé_x000D_
</label>

Curiously enough, the accepted answer does not actually answer the question directly. The question asks about using sed to replace a string, but the answer seems to presuppose knowledge of how to convert an arbitrary string into a regex.

Many programming language libraries have a function to perform such a transformation, e.g.

python: re.escape(STRING)
ruby: Regexp.escape(STRING)
java:  Pattern.quote(STRING)

But how to do it on the command line?

Since this is a sed-oriented question, one approach would be to use sed itself:

sed 's/\([\[/({.*+^$?]\)/\\\1/g'

So given an arbitrary string $STRING we could write something like:

re=$(sed 's/\([\[({.*+^$?]\)/\\\1/g' <<< "$STRING")
sed "/$re/d" FILE

or as a one-liner:

 sed "/$(sed 's/\([\[/({.*+^$?]\)/\\\1/g' <<< "$STRING")/d" 

with variations as described elsewhere on this page.

This is for latest iOS Versions(Modified with Xcode 9.3, Swift 4.1). Below are all the stages which makes the lifecycle of a UIViewController complete.

• loadView()

• loadViewIfNeeded()

• viewDidLoad()

• viewWillAppear(_ animated: Bool)

• viewWillLayoutSubviews()

• viewDidLayoutSubviews()

• viewDidAppear(_ animated: Bool)

• viewWillDisappear(_ animated: Bool)

• viewDidDisappear(_ animated: Bool)

Let me explain all those stages.

1. loadView

This event creates/loads the view that the controller manages. It can load from an associated nib file or an empty UIView if null was found. This makes it a good place to create your views in code programmatically.

This is where subclasses should create their custom view hierarchy if they aren't using a nib. Should never be called directly. Only override this method when you programmatically create views and assign the root view to the view property Don't call super method when you override loadView

2. loadViewIfNeeded

If incase the view of current viewController has not been set yet then this method will load the view but remember, this is only available in iOS >=9.0. So if you are supporting iOS <9.0 then don't expect it to come into the picture.

Loads the view controller's view if it has not already been set.

3. viewDidLoad

The viewDidLoad event is only called when the view is created and loaded into memory but the bounds for the view are not defined yet. This is a good place to initialise the objects that the view controller is going to use.

Called after the view has been loaded. For view controllers created in code, this is after -loadView. For view controllers unarchived from a nib, this is after the view is set.

4. viewWillAppear

This event notifies the viewController whenever the view appears on the screen. In this step the view has bounds that are defined but the orientation is not set.

Called when the view is about to made visible. Default does nothing.

5. viewWillLayoutSubviews

This is the first step in the lifecycle where the bounds are finalised. If you are not using constraints or Auto Layout you probably want to update the subviews here. This is only available in iOS >=5.0. So if you are supporting iOS <5.0 then don't expect it to come into the picture.

Called just before the view controller's view's layoutSubviews method is invoked. Subclasses can implement as necessary. The default is a nop.

6. viewDidLayoutSubviews

This event notifies the view controller that the subviews have been setup. It is a good place to make any changes to the subviews after they have been set. This is only available in iOS >=5.0. So if you are supporting iOS <5.0 then don't expect it to come into the picture.

Called just after the view controller's view's layoutSubviews method is invoked. Subclasses can implement as necessary. The default is a nop.

7. viewDidAppear

The viewDidAppear event fires after the view is presented on the screen. Which makes it a good place to get data from a backend service or database.

Called when the view has been fully transitioned onto the screen. Default does nothing

8. viewWillDisappear

The viewWillDisappear event fires when the view of presented viewController is about to disappear, dismiss, cover or hide behind other viewController. This is a good place where you can restrict your network calls, invalidate timer or release objects which is bound to that viewController.

Called when the view is dismissed, covered or otherwise hidden.

9. viewDidDisappear

This is the last step of the lifecycle that anyone can address as this event fires just after the view of presented viewController has been disappeared, dismissed, covered or hidden.

Called after the view was dismissed, covered or otherwise hidden. Default does nothing

Now as per Apple when you are implementing this methods you should remember to call super implementation of that specific method.

If you subclass UIViewController, you must call the super implementation of this method, even if you aren't using a NIB. (As a convenience, the default init method will do this for you, and specify nil for both of this methods arguments.) In the specified NIB, the File's Owner proxy should have its class set to your view controller subclass, with the view outlet connected to the main view. If you invoke this method with a nil nib name, then this class' -loadView method will attempt to load a NIB whose name is the same as your view controller's class. If no such NIB in fact exists then you must either call -setView: before -view is invoked, or override the -loadView method to set up your views programatically.

Hope this helped. Thanks.

UPDATE - As @ThomasW pointed inside comment viewWillLayoutSubviews and viewDidLayoutSubviews will also be called at other times when subviews of the main view are loaded, for example when cells of a table view or collection view are loaded.

UPDATE - As @Maria pointed inside comment, description of loadView was updated

In my case I have a git hook on commit, specified by admin. So it was not very convenient for me to change the script (with python3 calls).

And the simplest workaround was just to copy python.exe to python3.exe.

Now I could launch both python and python3.

Another to answer this question available here answered by @nilesh https://stackoverflow.com/a/19934852/2079692

public void setAttributeValue(WebElement elem, String value){
    JavascriptExecutor js = (JavascriptExecutor) driver;
    js.executeScript("arguments[0].setAttribute(arguments[1],arguments[2])",
        elem, "value", value
    );
}

this takes advantage of selenium findElementBy function where xpath can be used also.

Traditionally, if you only want to change the variable in your terminal windows, set it in .bashrc file, which is sourced each time a new terminal is opened. .profile file is not sourced each time you open a new terminal.

See the difference between .profile and .bashrc in question: What's the difference between .bashrc, .bash_profile, and .environment?

.bashrc should solve your problem. However, it is not the proper solution since you are using Ubuntu. See the relevant Ubuntu help page "Session-wide environment variables". Thus, no wonder that .profile does not work for you. I use Ubuntu 12.04 and xfce. I set up my .profile and it is simply not taking effect even if I log out and in. Similar experience here. So you may have to use .pam_environment file and totally forget about .profile, and .bashrc. And NOTE that .pam_environment is not a script file.

Check this out.

Code:

var myobj = {};
myobj.name="javascriptisawesome";
myobj.age=25;
myobj.mobile=123456789;
debugger;
var str = JSON.stringify(myobj);
alert(str);
var obj = JSON.parse(str);
alert(obj);

Editor warning: This solution is computationally inefficient and may bring down your connection for a large table.

NB - You need to do this first on a test copy of your table!

When I did it, I found that unless I also included AND n1.id <> n2.id, it deleted every row in the table.

1. If you want to keep the row with the lowest id value:

   DELETE n1 FROM names n1, names n2 WHERE n1.id > n2.id AND n1.name = n2.name
   

2. If you want to keep the row with the highest id value:

   DELETE n1 FROM names n1, names n2 WHERE n1.id < n2.id AND n1.name = n2.name
   

I used this method in MySQL 5.1

Not sure about other versions.

Update: Since people Googling for removing duplicates end up here
Although the OP's question is about DELETE, please be advised that using INSERT and DISTINCT is much faster. For a database with 8 million rows, the below query took 13 minutes, while using DELETE, it took more than 2 hours and yet didn't complete.

INSERT INTO tempTableName(cellId,attributeId,entityRowId,value)
    SELECT DISTINCT cellId,attributeId,entityRowId,value
    FROM tableName;

In my case, the problem was caused by Virtuous Ten Studio, which has the adb.exe in External/ADB directory.

Go there and run .\adb.exe kill-server and you'll be good.

Spring Framework provides an excellent utils class for achieving this.

Util class : NumberUtils

String to BigDecimal conversion -

NumberUtils.parseNumber("135.00", BigDecimal.class);

In one of my projects I run tests against Python 2 and 3. For that I wrote a small script which starts a local server independently:

$ python -m $(python -c 'import sys; print("http.server" if sys.version_info[:2] > (2,7) else "SimpleHTTPServer")')
Serving HTTP on 0.0.0.0 port 8000 ...

As an alias:

$ alias serve="python -m $(python -c 'import sys; print("http.server" if sys.version_info[:2] > (2,7) else "SimpleHTTPServer")')"
$ serve
Serving HTTP on 0.0.0.0 port 8000 ...

Please note that I control my Python version via conda environments, because of that I can use python instead of python3 for using Python 3.

`gcc -print-prog-name=cc1plus` -v

This command asks gcc which C++ preprocessor it is using, and then asks that preprocessor where it looks for includes.

You will get a reliable answer for your specific setup.

Likewise, for the C preprocessor:

`gcc -print-prog-name=cpp` -v

You can get all post data into this function :-

$postData = $request->post();

and if you want specific filed then use it :-

$request->post('current-password');

This worked for me. But there was a strange problem that even I tryed first those it didnt affect. I updated phpmyadmin page and got it somehow working.

If you need access to local-xampp-mysql. You can go to xampp-shell -> opening command prompt.

Then mysql -uroot -p --port=3306 or mysql -uroot -p (if there is password set). After that you can grant those acces from mysql shell page (also can work from localhost/phpmyadmin).

Just adding these if somebody find this topic and having beginner problems.

As of Git v2.23.0 (August 2019), git switch is preferred over git checkout when you’re simply switching branches/tags. I’m guessing they did this since git checkout had two functions: for switching branches and for restoring files. So in v2.23.0, they added two new commands, git switch, and git restore, to separate those concerns. I would predict at some point in the future, git checkout will be deprecated.

To switch to a normal branch, use git switch <branch-name>. To switch to a commit-like object, including single commits and tags, use git switch --detach <commitish>, where <commitish> is the tag name or commit number.

The --detach option forces you to recognize that you’re in a mode of “inspection and discardable experiments”. To create a new branch from the commitish you’re switching to, use git switch -c <new-branch> <start-point>.

Your Maven is reading Java version as 1.6.0_65, Where as the pom.xml says the version is 1.7.

Try installing the required verison.

If already installed check your $JAVA_HOME environment variable, it should contain the path of Java JDK 7. If you dont find it, fix your environment variable.

also remove the lines

 <fork>true</fork>
     <executable>${JAVA_1_7_HOME}/bin/javac</executable>

from the pom.xml

Add a try/catch block, if the transaction succeeds it will commit the changes, if the transaction fails the transaction is rolled back:

      VALUES ('Tidd130', 130), ('Tidd230', 230)

      UPDATE [Test].[dbo].[T1]
      SET [Title] = N'az2' ,[AVG] = 1
      WHERE [dbo].[T1].[Title] = N'az'

      COMMIT TRANSACTION [Tran1]

  END TRY

  BEGIN CATCH

Since you have wiped out your computer and want to checkout your project again, you could start by doing the below initial settings:

git config --global user.name "Your Name"
git config --global user.email [email protected]

Login to your github account, go to the repository you want to clone, and copy the URL under "Clone with HTTPS".

You can clone the remote repository by using HTTPS, even if you had setup SSH the last time:

git clone https://github.com/username/repo-name.git

NOTE:

If you had setup SSH for your remote repository previously, you will have to add that key to the known hosts ssh file on your PC; if you don't and try to do git clone [email protected]:username/repo-name.git, you will see an error similar to the one below:

Cloning into 'repo-name'...
The authenticity of host 'github.com (192.30.255.112)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXDoJWGl7E1IGOCspZomTxdCARLviMw6E5SY8.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'github.com,192.30.255.112' (RSA) to the list of known hosts.
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Using HTTPS is a easier than SSH in this case.

Both of the examples are in VB.NET.

Debug path:

TextBox1.Text = My.Application.Info.DirectoryPath

EXE path:

TextBox2.Text = IO.Path.GetFullPath(Application.ExecutablePath)

If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.

Something like:

$("#fbss").keypress(function() {
    if($(this).val().length > 1) {
         // Enable submit button
    } else {
         // Disable submit button
    }
});

I have had a similar problem.

Under "problems" tab I have found an error saying "Error generating final archive: Debug Certificate expired on 2/22/12 1:49 PM"

So my advice is to look in the problems tab to get some more info.

Turns out... we had to also chmod 755 the parent directory, user, in addition to xxx.

$('div.alldivs :first-child');

Or you can just refer to the id directly:

$('#div1');

As suggested, you might be better of using the child selector:

$('div.alldivs > div:first-child')

If you dont have to use first-child, you could use :first as also suggested, or $('div.alldivs').children(0).

The set statement doesn't treat spaces the way you expect; your variable is really named Pathname[space] and is equal to [space]C:\Program Files.

Remove the spaces from both sides of the = sign, and put the value in double quotes:

set Pathname="C:\Program Files"

Also, if your command prompt is not open to C:\, then using cd alone can't change drives.

Use

cd /d %Pathname%

or

pushd %Pathname%

instead.

In Maven project, You can build jar automatically using Maven War plugin by setting archiveClasses to true. Example below.

<plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-war-plugin</artifactId>
       <configuration>
        <archiveClasses>true</archiveClasses>
       </configuration>
</plugin>

Ciro's solution about an SVG Data URI background containing the text is very clever.

However, it won't work in IE if you just add the plain SVG source to the data URI.

In order to get around this and make it work in IE9 and up, encode the SVG to base64. This is a great tool.

So this:

background:url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg"><text x="5%" y="5%" font-size="30" fill="red">I love SVG!</text></svg>');

Becomes this:

background:url('data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjx0ZXh0IHg9IjUlIiB5PSI1JSIgZm9udC1zaXplPSIzMCIgZmlsbD0icmVkIj5JIGxvdmUgU1ZHITwvdGV4dD48L3N2Zz4=');

Tested and it works in IE9-10-11, WebKit (Chrome 37, Opera 23) and Gecko (Firefox 31).

http://jsfiddle.net/qapp5dLn/

Use org.apache.commons.lang3.StringUtils

String emptyString = new String();    
result = StringUtils.defaultIfEmpty(emptyString, "default");
System.out.println(result);

String nullString = null;
result = StringUtils.defaultIfEmpty(nullString, "default");
System.out.println(result);

Both of the above options will print:

My first choice is Android Studio. its has great feature to develop android application.

Eclipse is not that hard to learn also.If you're going to be learning Android development from the start, I can recommend Hello, Android, which I just finished. It shows you exactly how to use all the features of Eclipse that are useful for developing Android apps. There's also a brief section on getting set up to develop from the command line and from other IDEs.

I have encountered this error during unit testing of a component (only during testing, within application it worked normally). The solution is to import ReactiveFormsModule in .spec.ts file:

// Import module
import { ReactiveFormsModule } from '@angular/forms';

describe('MyComponent', () => {
    beforeEach(async(() => {
        TestBed.configureTestingModule({
            declarations: [MyComponent],
            imports: [ReactiveFormsModule],  // Also add it to 'imports' array
        })
        .compileComponents();
    }));
});

If you don't mind a third-party dependency, you should consider using my OS-Lib library. This makes reading/writing files and working with the filesystem very convenient:

// Make sure working directory exists and is empty
val wd = os.pwd/"out"/"splash"
os.remove.all(wd)
os.makeDir.all(wd)

// Read/write files
os.write(wd/"file.txt", "hello")
os.read(wd/"file.txt") ==> "hello"

// Perform filesystem operations
os.copy(wd/"file.txt", wd/"copied.txt")
os.list(wd) ==> Seq(wd/"copied.txt", wd/"file.txt")

with one-line helpers for reading bytes, reading chunks, reading lines, and many other useful/common operations

Can also use:

find . -mindepth 1 -mtime +3 -delete

To not delete target directory

I had a similar issue and it turned out that i had to add an extra entry in cmake to include the files.

Since i was also using the zmq library I had to add this to the included libraries as well.

I am not sure, but it might be worth running an eval on the commands first.

This will let bash expand the variables $TAR_CMD and such to their full breadth(just as the echo command does to the console, which you say works)

Bash will then read the line a second time with the variables expanded.

eval $TAR_CMD | $ENCRYPT_CMD | $SPLIT_CMD 

I just did a Google search and this page looks like it might do a decent job at explaining why that is needed. http://fvue.nl/wiki/Bash:_Why_use_eval_with_variable_expansion%3F

The reason you are getting the unexpected result is that hist(...) calculates the distribution from a numeric vector. In your code, table(animalFactor) behaves like a numeric vector with three elements: 1, 3, 7. So hist(...) plots the number of 1's (1), the number of 3's (1), and the number of 7's (1). @Roland's solution is the simplest.

Here's a way to do this using ggplot:

library(ggplot2)
ggp <- ggplot(data.frame(animals),aes(x=animals))
# counts
ggp + geom_histogram(fill="lightgreen")
# proportion
ggp + geom_histogram(fill="lightblue",aes(y=..count../sum(..count..)))

You would get precisely the same result using animalFactor instead of animals in the code above.

One advantage your current approach does have is that it will raise an error if multiple rows are returned by the predicate. To reproduce that you can use.

SELECT @currentTerm = currentterm,
       @termID = termid,
       @endDate = enddate
FROM   table1
WHERE  iscurrent = 1

IF( @@ROWCOUNT <> 1 )
  BEGIN
      RAISERROR ('Unexpected number of matching rows',
                 16,
                 1)

      RETURN
  END  

I tried these steps: https://developers.facebook.com/docs/marketing-api/access#graph-api-explorer

Get Permanent Page Access Token

• Go to Graph API Explorer
• Select your app in Application
• Paste the long-lived access token into Access Token
• Next to Access Token, choose the page you want an access token for. The access token appears as a new string.
• Click i to see the properties of this access token
• Click “Open in Access Token Tool” button again to open the “Access Token Debugger” tool to check the properties

One Tip, it only worked for me when the page language is english.

Try this,

$('.popup').click(function(event) {
    event.preventDefault();
    window.open($(this).attr("href"), "popupWindow", "width=600,height=600,scrollbars=yes");
});

You have to include jQuery reference to work this, here is the working sampe http://jsfiddle.net/a7qJt/

When you cherry-pick, it creates a new commit with a new SHA. If you do:

git cherry-pick -x <sha>

then at least you'll get the commit message from the original commit appended to your new commit, along with the original SHA, which is very useful for tracking cherry-picks.

I think that you'll find interesting stuff in the following answer of mine that I did for a previous similar question:

In this answer, I proposed a pattern that allows a regex to catch any kind of number and since I have nothing else to add to it, I think it is fairly complete

It appears the following answer no longer works, and Facebook no longer accepts parameters on the Feed Dialog links

You can use the Feed Dialog via URL to emulate the behavior of Sharer.php, but it's a little more complicated. You need a Facebook App setup with the Base URL of the URL you plan to share configured. Then you can do the following:

1) Create a link like:

   http://www.facebook.com/dialog/feed?app_id=[FACEBOOK_APP_ID]' +
        '&link=[FULLY_QUALIFIED_LINK_TO_SHARE_CONTENT]' +
        '&picture=[LINK_TO_IMAGE]' +
        '&name=' + encodeURIComponent('[CONTENT_TITLE]') +
        '&caption=' + encodeURIComponent('[CONTENT_CAPTION]) +
        '&description=' + encodeURIComponent('[CONTENT_DESCRIPTION]') +
        '&redirect_uri=' + FBVars.baseURL + '[URL_TO_REDIRECT_TO_AFTER_SHARE]' +
        '&display=popup';

(obviously replace the [CONTENT] with the appropriate content. Documentation here: https://developers.facebook.com/docs/reference/dialogs/feed)

2) Open that link in a popup window with JavaScript on click of the share link

3) I like to create file (i.e. popupclose.html) to redirect users back to when they finish sharing, this file will contain <script>window.close();</script> to close the popup window

The only downside of using the Feed Dialog (besides setup) is that, if you manage Pages as well, you don't have the ability to choose to share via a Page, only a regular user account can share. And it can give you some really cryptic error messages, most of them are related to the setup of your Facebook app or problems with either the content or URL you are sharing.

The spring docs are great on this: 3.8.1. BeanFactory or ApplicationContext?. They have a table with a comparison, I'll post a snippet:

Bean Factory

• Bean instantiation/wiring

Application Context

• Bean instantiation/wiring
• Automatic BeanPostProcessor registration
• Automatic BeanFactoryPostProcessor registration
• Convenient MessageSource access (for i18n)
• ApplicationEvent publication

So if you need any of the points presented on the Application Context side, you should use ApplicationContext.

Edit #3:

The Navigation Drawer pattern is officially described in the Android documentation!

Check out the following links:

• Design docs can be found here.
• Developer docs can be found here.

Edit #2:

Roman Nurik (an Android design engineer at Google) has confirmed that the recommended behavior is to not move the Action Bar when opening the drawer (like the YouTube app). See this Google+ post.

Edit #1:

I answered this question a while ago, but I'm back to re-emphasize that Prixing has the best fly-out menu out there... by far. It's absolutely beautiful, perfectly smooth, and it puts Facebook, Google+, and YouTube to shame. EverNote is pretty good too... but still not as perfect as Prixing. Check out this series of posts on how the flyout menu was implemented (from none other than the head developer at Prixing himself!).

Original Answer:

Adam Powell and Richard Fulcher talk about this at 49:47 - 52:50 in the Google I/O talk titled "Navigation in Android".

To summarize their answer, as of the date of this posting the slide out navigation menu is not officially part of the Android application design standard. As you have probably discovered, there's currently no native support for this feature, but there was talk about making this an addition to an upcoming revision of the support package.

With regards to the YouTube and G+ apps, it does seem odd that they behave differently. My best guess is that the reason the YouTube app fixes the position of the action bar is,

1. One of the most important navigational options for users using the YouTube app is search, which is performed in the SearchView in the action bar. It would make sense to make the action bar static in this regard, since it would allow the user to always have the option to search for new videos.

2. The G+ app uses a ViewPager to display its content, so making the pull out menu specific to the layout content (i.e. everything under the action bar) wouldn't make much sense. Swiping is supposed to provide a means of navigating between pages, not a means of global navigation. This might be why they decided to do it differently in the G+ app than they did in the YouTube app.

   On another note, check out the Google Play app for another version of the "pull out menu" (when you are at the left most page, swipe left and a pull out, "half-page" menu will appear).

You're right in that this isn't very consistent behavior, but it doesn't seem like there is a 100% consensus within the Android team on how this behavior should be implemented yet. I wouldn't be surprised if in the future the apps are updated so that the navigation in both apps are identical (they seemed very keen on making navigation consistent across all Google-made apps in the talk).

You could try adding a bool so the algorithm would know when the button was activated. When it's clicked, the bool checks true, the new form shows and the last gets closed.

It's important to know that forms consume some ram (at least a little bit), so it's a good idea to close those you're not gonna use, instead of just hiding it. Makes the difference in big projects.

This issue actually caused by different users who wants to write/read file but denied cause different ownership. maybe you as 'root' installed laravel before then you login into your site as 'laravel' user where 'laravel' the default ownership, so this is the actually real issue here. So when user 'laravel' want to read/write all file in disk as default, to be denied, cause that file has ownership by 'root'.

To solving this problem you can follow like this:

sudo chown -hR your-user-name /root /nameforlder

or in my case

sudo chown -hR igmcoid /root /sublaravel

Footnote:

1. root as name first ownership who installed before
2. your-user-name as the default ownership who actually write/read in site.
3. namefolder as name folder that want you change the ownership.

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

One form to do this is insert the panel that you want to expand inside a DIV setted as relative: let me show you:

<div style="position:relative">
  <div style="position:absolute; z-index: 1000;">
    your code
  </div>
</div>

You use the first div to position the inner content in a specific area inside your page and the second absolute should be referred to the container (because is relative) The z-index in this case is referred also to container and if it higher that the container should be at top. You can put the style in a CSS class and change the size of the absolute div to expand it on hover or another action that you want to control.

ExecuteNonQuery

This ExecuteNonQuery method will be used only for insert, update and delete, Create, and SET statements. ExecuteNonQuery method will return number of rows effected with INSERT, DELETE or UPDATE operations.

ExecuteScalar

It’s very fast to retrieve single values from database. Execute Scalar will return single row single column value i.e. single value, on execution of SQL Query or Stored procedure using command object. ExecuteReader

Execute Reader will be used to return the set of rows, on execution of SQL Query or Stored procedure using command object. This one is forward only retrieval of records and it is used to read the table values from first to last.

This error can happen because some MFC library (eg. mfc120.dll) from which the DLL is dependent is missing in windows/system32 folder.

I will explain with simple example

1. [1,3,2] <=> [2,2,2]

   Ruby will start comparing each element of both array from left hand side. 1 for left array is smaller than 2 of right array. Hence left array is smaller than right array. Output will be -1.

2. [2,3,2] <=> [2,2,2]

   As above it will first compare first element which are equal then it will compare second element, in this case second element of left array is greater hence output is 1.

Another option is to add style to div

<div style="position: absolute; height:somePercentage%; overflow:auto(or other overflow value)">
 //to be scrolled 
</div>

And it means that an element is positioned relative to the nearest positioned ancestor.

Ok, I finally resolved this, by completely de-installing Android-Studio, and then installing the latest (0.2.0) from scratch.

EDIT: I also had to use the Android SDK-Manager, and install the component in the 'Extras' section called the Android Support Repository (as mentioned elsewhere).

Note: This does NOT fix my old existing project...that one still will not build, as indicated above.

But, it DOES solve the issue of now being able to at least create NEW projects going forward, that build ok using 'Gradle'. (So, basically, I re-created my proj from scratch under a new name, and copied all my code and project xml-files, etc, from the old project, into the newly-created one.)

[As an aside: I've got an idea, Google! Why don't you refer to versions of Android-Studio using numbers like 0.1.9 and 0.2.0, but then when users click on 'About' menu item, or search elsewhere for what version they are running, you could baffle them with crap like 'the July 11th build' or aka, some build number with 6 or 8 digits of numbering, and make them wonder what version they actually have! That will keep the developers guessing...really will sort the wheat from the chaff, etc.]

For example, I originally installed a kit named: android-studio-bundle-130.687321-windows.exe

Today, I got the "0.2.0" kit???, and it has a name like: android-studio-bundle-130.737825-windows.exe

Yep, this version #ing system is about as clear as mud.
Why bother with the illusion of version#s, when you don't use them!!!???

Be aware that when you do press your <leader> key you have only 1000ms (by default) to enter the command following it.

This is exacerbated because there is no visual feedback (by default) that you have pressed your <leader> key and vim is awaiting the command; and so there is also no visual way to know when this time out has happened.

If you add set showcmd to your vimrc then you will see your <leader> key appear in the bottom right hand corner of vim (to the left of the cursor location) and perhaps more importantly you will see it disappear when the time out happens.

The length of the timeout can also be set in your vimrc, see :help timeoutlen for more information.

For your first method change ws.Range("A") to ws.Range("A:A") which will search the entirety of column a, like so:

Sub Find_Bingo()

        Dim wb As Workbook
        Dim ws As Worksheet
        Dim FoundCell As Range
        Set wb = ActiveWorkbook
        Set ws = ActiveSheet

            Const WHAT_TO_FIND As String = "Bingo"

            Set FoundCell = ws.Range("A:A").Find(What:=WHAT_TO_FIND)
            If Not FoundCell Is Nothing Then
                MsgBox (WHAT_TO_FIND & " found in row: " & FoundCell.Row)
            Else
                MsgBox (WHAT_TO_FIND & " not found")
            End If
End Sub

For your second method, you are using Bingo as a variable instead of a string literal. This is a good example of why I add Option Explicit to the top of all of my code modules, as when you try to run the code it will direct you to this "variable" which is undefined and not intended to be a variable at all.

Additionally, when you are using With...End With you need a period . before you reference Cells, so Cells should be .Cells. This mimics the normal qualifying behavior (i.e. Sheet1.Cells.Find..)

Change Bingo to "Bingo" and change Cells to .Cells

With Sheet1
        Set FoundCell = .Cells.Find(What:="Bingo", After:=.Cells(1, 1), _
        LookIn:=xlValues, lookat:=xlPart, SearchOrder:=xlByRows, _
        SearchDirection:=xlNext, MatchCase:=False, SearchFormat:=False)
    End With

If Not FoundCell Is Nothing Then
        MsgBox ("""Bingo"" found in row " & FoundCell.Row)
Else
        MsgBox ("Bingo not found")
End If

Update

In my

With Sheet1
    .....
End With

The Sheet1 refers to a worksheet's code name, not the name of the worksheet itself. For example, say I open a new blank Excel workbook. The default worksheet is just Sheet1. I can refer to that in code either with the code name of Sheet1 or I can refer to it with the index of Sheets("Sheet1"). The advantage to using a codename is that it does not change if you change the name of the worksheet.

Continuing this example, let's say I renamed Sheet1 to Data. Using Sheet1 would continue to work, as the code name doesn't change, but now using Sheets("Sheet1") would return an error and that syntax must be updated to the new name of the sheet, so it would need to be Sheets("Data").

In the VB Editor you would see something like this:

Notice how, even though I changed the name to Data, there is still a Sheet1 to the left. That is what I mean by codename.

The Data worksheet can be referenced in two ways:

Debug.Print Sheet1.Name
Debug.Print Sheets("Data").Name

Both should return Data

More discussion on worksheet code names can be found here.

There is collection of Func<...> classes - Func that is probably what you are looking for:

 void MyMethod(Func<int> param1 = null) 

This defines method that have parameter param1 with default value null (similar to AS), and a function that returns int. Unlike AS in C# you need to specify type of the function's arguments.

So if you AS usage was

MyMethod(function(intArg, stringArg) { return true; }) 

Than in C# it would require param1 to be of type Func<int, siring, bool> and usage like

MyMethod( (intArg, stringArg) => { return true;} ); 

This was my case

I had a entity Student which was having many-to-one relation with another entity Classes (the classes which he studied).

I wanted to save the data into another table, which was having foreign keys of both Student and Classes. At some instance of execution, I was bringing a List of Students under some conditions, and each Student will have a reference of Classes class.

Sample code :-

Iterator<Student> itr = studentId.iterator();
while (itr.hasNext()) 
{
    Student student = (Student) itr.next();
    MarksCardSiNoGen bo = new MarksCardSiNoGen();

    bo.setStudentId(student);

    Classes classBo = student.getClasses();

    bo.setClassId(classBo);
}

Here you can see that, I'm setting both Student and Classes reference to the BO I want to save. But while debugging when I inspected student.getClasses() it was showing this exception(com.sun.jdi.InvocationException).

The problem I found was that, after fetching the Student list using HQL query, I was flushing and closing the session. When I removed that session.close(); statement the problem was solved.

The session was closed when I finally saved all the data into table(MarksCardSiNoGen).

Hope this helps.

I was facing the same error with Spring Boot dependencies. What solved for me was letting Maven resolve the dependencies wrapping them with dependency management:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.0.RELEASE</version>
</parent>

<dependencyManagement>
    <dependencies>
      <dependency>...</dependency>
      ...
    </dependencies>
</dependencyManagement>

You can use the command split for this task. For example this command entered into the command prompt

split YourLogFile.txt -b 500m

creates several files with a size of 500 MByte each. This will take several minutes for a file of your size. You can rename the output files (by default called "xaa", "xab",... and so on) to *.txt to open it in the editor of your choice.

Make sure to check the help file for the command. You can also split the log file by number of lines or change the name of your output files.

(tested on Windows 7 64 bit)

There is also a POSIX library for POSIX operating systems. Check for compatability

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
#include <iostream>

void *task(void *argument){
      char* msg;
      msg = (char*)argument;
      std::cout<<msg<<std::endl;
}

int main(){
    pthread_t thread1, thread2;
    int i1,i2;
    i1 = pthread_create( &thread1, NULL, task, (void*) "thread 1");
    i2 = pthread_create( &thread2, NULL, task, (void*) "thread 2");

    pthread_join(thread1,NULL);
    pthread_join(thread2,NULL);
    return 0;

}

compile with -lpthread

In git version 2.14.3,

You can remove upstream using

git branch --unset-upstream

The above command will also remove the tracking stream branch, hence if you want to rebase from repository you have use

git rebase origin master 

instead of git pull --rebase

To loop from current record to the end:

While Me.CurrentRecord < Me.Recordset.RecordCount
    ' ... do something to current record
    ' ...

    DoCmd.GoToRecord Record:=acNext
Wend

To check if it is possible to go to next record:

If Me.CurrentRecord < Me.Recordset.RecordCount Then
    ' ...
End If

What worked for me was going to the article someone else had already mentioned, but keying on this piece:

application.config.backup is not created by automatic backup. The backup files are in %systemdrive%\inetpub\history directory. Automatic backup is also a Vista SP1 and above feature. More information can be found in this blog post, http://blogs.iis.net/bills/archive/2008/03/24/how-to-backup-restore-iis7-configuration.aspx

I was able to find backups of my settings from when I had first installed IIS, and just copy and replace the files in the inetsrv\config directory.

If you have control of the page hosting the iframe and the page of the iframe, you can pass a query parameter to the iframe...

Here's an example to add a class to the iframe based on whether or not the hosting site is mobile...

Adding iFrame:

var isMobile=$("mobile").length; //detect if page is mobile
var iFrameUrl ="https://myiframesite/?isMobile=" + isMobile; 

$(body).append("<div id='wrapper'><iframe src=''></iframe></div>");
$("#wrapper iframe").attr("src", iFrameUrl ); 

Inside iFrame:

//add mobile class if needed
var url = new URL(window.location.href);
var isMobile = url.searchParams.get("isMobile");
if(isMobile == "1") {
    $("body").addClass("mobile");
}

Let's break >> /dev/null 2>&1 statement into parts:

Part 1: >> output redirection

This is used to redirect the program output and append the output at the end of the file. More...

Part 2: /dev/null special file

This is a Pseudo-devices special file.

Command ls -l /dev/null will give you details of this file:

crw-rw-rw-. 1 root root 1, 3 Mar 20 18:37 /dev/null

Did you observe crw? Which means it is a pseudo-device file which is of character-special-file type that provides serial access.

/dev/null accepts and discards all input; produces no output (always returns an end-of-file indication on a read). Reference: Wikipedia

Part 3: 2>&1 file descriptor

Whenever you execute a program, the operating system always opens three files, standard input, standard output, and standard error as we know whenever a file is opened, the operating system (from kernel) returns a non-negative integer called a file descriptor. The file descriptor for these files are 0, 1, and 2, respectively.

So 2>&1 simply says redirect standard error to standard output.

& means whatever follows is a file descriptor, not a filename.

In short, by using this command you are telling your program not to shout while executing.

What is the importance of using 2>&1?

If you don't want to produce any output, even in case of some error produced in the terminal. To explain more clearly, let's consider the following example:

$ ls -l > /dev/null

For the above command, no output was printed in the terminal, but what if this command produces an error:

$ ls -l file_doesnot_exists > /dev/null
ls: cannot access file_doesnot_exists: No such file or directory

Despite I'm redirecting output to /dev/null, it is printed in the terminal. It is because we are not redirecting error output to /dev/null, so in order to redirect error output as well, it is required to add 2>&1:

$ ls -l file_doesnot_exists > /dev/null 2>&1

The instances of the new HttpHeader class are immutable objects. Invoking class methods will return a new instance as result. So basically, you need to do the following:

let headers = new HttpHeaders();
headers = headers.set('Content-Type', 'application/json; charset=utf-8');

or

const headers = new HttpHeaders({'Content-Type':'application/json; charset=utf-8'});

Update: adding multiple headers

let headers = new HttpHeaders();
headers = headers.set('h1', 'v1').set('h2','v2');

or

const headers = new HttpHeaders({'h1':'v1','h2':'v2'});

Update: accept object map for HttpClient headers & params

Since 5.0.0-beta.6 is now possible to skip the creation of a HttpHeaders object an directly pass an object map as argument. So now its possible to do the following:

http.get('someurl',{
   headers: {'header1':'value1','header2':'value2'}
});

Try the code below to prevent the default behaviour scrolling back to the top of the page

$(document).ready(function() {   
  $('.galleryicon').live("click", function(e) {  // the (e) represent the event
    $('#mainImage').hide();     
    $('#cakebox').css('background-image', "url('ajax-loader.gif')");     
    var i = $('<img />').attr('src',this.href).load(function() {         
      $('#mainImage').attr('src', i.attr('src'));         
      $('#cakebox').css('background-image', 'none');         
      $('#mainImage').fadeIn();     
    });
  e.preventDefault(); //Prevent default click action which is causing the 
  return false;       //page to scroll back to the top
  });  
});

For more information on event.preventDefault() have a look here at the official documentation.

What you are looking for is 'type casting'. typecasting (putting the type you know you want in brackets) tells the compiler you know what you are doing and are cool with it. The old way that is inherited from C is as follows.

float var_a = 9.99;
int   var_b = (int)var_a;

If you had only tried to write

int var_b = var_a;

You would have got a warning that you can't implicitly (automatically) convert a float to an int, as you lose the decimal.

This is referred to as the old way as C++ offers a superior alternative, 'static cast'; this provides a much safer way of converting from one type to another. The equivalent method would be (and the way you should do it)

float var_x = 9.99;
int   var_y = static_cast<int>(var_x);

This method may look a bit more long winded, but it provides much better handling for situations such as accidentally requesting a 'static cast' on a type that cannot be converted. For more information on the why you should be using static cast, see this question.

I don't have much experience with Flexbox but it seems to me that the forced height on the html and body tags cause the text to disappear on top when resized-- I wasn't able to test in IE but I found the same effect in Chrome.

I forked your fiddle and removed the height and width declarations.

body
{
    margin: 0;
}

It also seemed like the flex settings must be applied to other flex elements. However, applying display: flex to the .inner caused issues so I explicitly set the .inner to display: block and set the .outer to flex for positioning.

I set the minimum .outer height to fill the viewport, the display: flex, and set the horizontal and vertical alignment:

.outer
{
    display:flex;
    min-height: 100%;
    min-height: 100vh;
    align-items: center;
    justify-content: center;
}

I set .inner to display: block explicitly. In Chrome, it looked like it inherited flex from .outer. I also set the width:

.inner
{
    display:block;
    width: 80%;
}

This fixed the issue in Chrome, hopefully it might do the same in IE11. Here's my version of the fiddle: http://jsfiddle.net/ToddT/5CxAy/21/

ID tag - used by CSS, define a unique instance of a div, span or other elements. Appears within the Javascript DOM model, allowing you to access them with various function calls.

Name tag for fields - This is unique per form -- unless you are doing an array which you want to pass to PHP/server-side processing. You can access it via Javascript by name, but I think that it does not appear as a node in the DOM or some restrictions may apply (you cannot use .innerHTML, for example, if I recall correctly).

The :nth-child() and :nth-of-type() pseudo-classes allows you to select elements with a formula.

The syntax is :nth-child(an+b), where you replace a and b by numbers of your choice.

For instance, :nth-child(3n+1) selects the 1st, 4th, 7th etc. child.

td:nth-child(3n+1) {  
  /* your stuff here */
}

:nth-of-type() works the same, except that it only considers element of the given type ( in the example).

Instance variables are common to every object that you creating. say, there is two instance variables

class ExpThisKeyWord{
int x;
int y;

public void setMyInstanceValues(int a, int b) {
    x= a;
    y=b;

    System.out.println("x is ="+x);
    System.out.println("y is ="+y);
}

}




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

ExpThisKeyWord obj1 = new ExpThisKeyWord();
ExpThisKeyWord obj2 = new ExpThisKeyWord();
ExpThisKeyWord obj3 = new ExpThisKeyWord();

obj1.setMyInstanceValues(1, 2);
obj2.setMyInstanceValues(11, 22);
obj3.setMyInstanceValues(111, 222);



}
}

if you noticed above code, we have initiated three objects and three objects are calling SetMyInstanceValues method. How do you think JVM correctly assign the values for every object? there is the trick, JVM will not see this code how it is showed above. instead of that, it will see like below code;

public void setMyInstanceValues(int a, int b) {
    this.x= a; //Answer: this keyword denotes the current object that is handled by JVM.
    this.y=b;

    System.out.println("x is ="+x);
    System.out.println("y is ="+y);
}

Few answers that may be useful, especially if you have dynamic content.

$('#dialogueForm').live("dialogclose", function(){
   //your code to run on dialog close

Or, when opening the modal, have a callback.

$( "#dialogueForm" ).dialog({
              autoOpen: false,
              height: "auto",
              width: "auto",
              modal: true,
                my: "center",
                at: "center",
                of: window,
              close : function(){
                  // functionality goes here
              }  
              });

Rabin-Miller is a standard probabilistic primality test. (you run it K times and the input number is either definitely composite, or it is probably prime with probability of error 4^-K. (a few hundred iterations and it's almost certainly telling you the truth)

There is a non-probabilistic (deterministic) variant of Rabin Miller.

The Great Internet Mersenne Prime Search (GIMPS) which has found the world's record for largest proven prime (2^74,207,281 - 1 as of June 2017), uses several algorithms, but these are primes in special forms. However the GIMPS page above does include some general deterministic primality tests. They appear to indicate that which algorithm is "fastest" depends upon the size of the number to be tested. If your number fits in 64 bits then you probably shouldn't use a method intended to work on primes of several million digits.

Using the git rm --cached command does not answer the original question:

How do you force git to completely forget about [a file]?

In fact, this solution will cause the file to be deleted in every other instance of the repository when executing a git pull!

The correct way to force git to forget about a file is documented by GitHub here.

I recommend reading the documentation, but basically:

git fetch --all
git filter-branch --force --index-filter 'git rm --cached --ignore-unmatch full/path/to/file' --prune-empty --tag-name-filter cat -- --all
git push origin --force --all
git push origin --force --tags
git for-each-ref --format='delete %(refname)' refs/original | git update-ref --stdin
git reflog expire --expire=now --all
git gc --prune=now

just replace full/path/to/file with the full path of the file. Make sure you've added the file to your .gitignore.

You'll also need to (temporarily) allow non-fast-forward pushes to your repository, since you're changing your git history.

We have seen this same behavior in the past. It turned out that, for some crazy reason, if a NullPointerException occurred at the same place in the code multiple times, after a while using Log.error(String, Throwable) would stop including full stack traces.

Try looking further back in your log. You may find the culprit.

EDIT: this bug sounds relevant, but it was fixed so long ago it's probably not the cause.

Try below piece of code.

this.dataGridView1.RefreshEdit();

The previously linked solution is a horrible piece of code; nearly every line contains a bug. Use fgetcsv instead:

<?php
echo "<html><body><table>\n\n";
$f = fopen("so-csv.csv", "r");
while (($line = fgetcsv($f)) !== false) {
        echo "<tr>";
        foreach ($line as $cell) {
                echo "<td>" . htmlspecialchars($cell) . "</td>";
        }
        echo "</tr>\n";
}
fclose($f);
echo "\n</table></body></html>";

May I present my guess, since this is not a open technology.

Google says it's about combing information from before, during, after to distinguish human from robot. But I am more interested about that final click on the check box.

Say, the POST data (solved CAPTCHA) has a field called fingerprint, a string calculated from user behavior. I think there may be a field about that check box location. I guess this check box is in a coordinate system randomly generated by Google back-end and encrypted by the public key of my site. So, a robot may "guess/calculate" a location about this box, but when site owner makes the GET query with private key to verify user identity, Google will decrypt the coordinate system and say if the user click on the right place. So, only one possible right click(with some offsets, it's a square box) location in this random coordinate system owned by only Google and site owners.

The following will order your data depending on both column in descending order.

ORDER BY article_rating DESC, article_time DESC

Not renaming it, but perhaps generating the name correctly in the first place would help? Change apk name with Gradle

Just Do it.....

( It will create same table structure as from table as to table with same data )

 create table toDatabaseName.toTableName as select * from fromDatabaseName.fromTableName;

Try adding the -f option to show the function names :

addr2line -f -e a.out 0x4005BDC

Use JsonResponse

from django.http import JsonResponse

names=[line.strip() for line in open('names.txt')]

This is a quite confusing way of using Apache configuration directives.

Technically, the first bit is equivalent to

Allow From All

This is because Order Deny,Allow makes the Deny directive evaluated before the Allow Directives. In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.

Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.

The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.

Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.

It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.

The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):

#
# The following lines prevent .htaccess and .htpasswd files from being 
# viewed by Web clients. 
#
<Files ~ "^\.ht">
    Order allow,deny
    Deny from all
    Satisfy all
</Files>

which forbids access to any file beginning by ".ht".

The equivalent Apache 2.4 configuration should look like:

<Files ~ "^\.ht">
    Require all denied
</Files>

I would like to update the answers above to 2018 and say to use both VisualVM and Eclipse MAT.

How to use:

VisualVM is used for live monitoring and dump heap. You can also analyze the heap dumps there with great power, however MAT have more capabilities (such as automatic analysis to find leaks) and therefore, I read the VisualVM dump output (.hprof file) into MAT.

Get VisualVM:

Download VisualVM here: https://visualvm.github.io/

You also need to download the plugin for Intellij:

Then you'll see in intellij another 2 new orange icons:

Once you run your app with an orange one, in VisualVM you'll see your process on the left, and data on the right. Sit some time and learn this tool, it is very powerful:

Get Eclipse's Memory Analysis Tool (MAT) as a standalone:

Download here: https://www.eclipse.org/mat/downloads.php

And this is how it looks:

Hope it helps!

The omp_get_num_threads() function returns the number of threads that are currently in the team executing the parallel region from which it is called. You are calling it outside of the parallel region, which is why it returns 1.

About CharsetFilter mentioned in @kosoant answer ....

There is a build in Filter in tomcat web.xml (located at conf/web.xml). The filter is named setCharacterEncodingFilter and is commented by default. You can uncomment this ( Please remember to uncomment its filter-mapping too )

Also there is no need to set jsp-config in your web.xml (I have test it for Tomcat 7+ )

Added another case to Michal Górny's answer:

Note that relative imports are based on the name of the current module. Since the name of the main module is always "__main__", modules intended for use as the main module of a Python application must always use absolute imports.

something like this ? :

DataTable dt = ...
DataView dv = new DataView(dt);
dv.RowFilter = "(EmpName != 'abc' or EmpName != 'xyz') and (EmpID = 5)"

Is it what you are searching for?

I for myself prefer Lukas Edger's solution.

But you might want to know there is also a function SYS_GUID which can be applied as a default value to a column and generate unique ids.

Schema is an encapsulation of DB.objects about an idea/domain of intrest, and owned by ONE user. It then will be shared by other users/applications with suppressed roles. So users need not own a schema, but a schema needs to have an owner.

Description and examples can be found in IEEE Std 1800-2017 § 11.5.1 "Vector bit-select and part-select addressing". First IEEE appearance is IEEE 1364-2001 (Verilog) § 4.2.1 "Vector bit-select and part-select addressing". Here is an direct example from the LRM:

logic [31: 0] a_vect;
logic [0 :31] b_vect;
logic [63: 0] dword;
integer sel;
a_vect[ 0 +: 8] // == a_vect[ 7 : 0]
a_vect[15 -: 8] // == a_vect[15 : 8]
b_vect[ 0 +: 8] // == b_vect[0 : 7]
b_vect[15 -: 8] // == b_vect[8 :15]
dword[8*sel +: 8] // variable part-select with fixed width

If sel is 0 then dword[8*(0) +: 8] == dword[7:0]
If sel is 7 then dword[8*(7) +: 8] == dword[63:56]

The value to the left always the starting index. The number to the right is the width and must be a positive constant. the + and - indicates to select the bits of a higher or lower index value then the starting index.

Assuming address is in little endian ([msb:lsb]) format, then if(address[2*pointer+:2]) is the equivalent of if({address[2*pointer+1],address[2*pointer]})

From kitkat onwards use evaluateJavascript method instead loadUrl to call the javascript functions like below

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
        webView.evaluateJavascript("enable();", null);
    } else {
        webView.loadUrl("javascript:enable();");
    }

Bojan Milic answer work in a way but it error out with a message below,

}

I had the following problem where I was fetching data from a database and wanted to display a string containing \n. None of the solutions above worked for me and I finally came up with a solution: https://stackoverflow.com/a/61484190/7251208

Machine code is binary (1's and 0's) code that can be executed directly by the CPU. If you open a machine code file in a text editor you would see garbage, including unprintable characters (no, not those unprintable characters ;) ).

Object code is a portion of machine code not yet linked into a complete program. It's the machine code for one particular library or module that will make up the completed product. It may also contain placeholders or offsets not found in the machine code of a completed program. The linker will use these placeholders and offsets to connect everything together.

Assembly code is plain-text and (somewhat) human read-able source code that mostly has a direct 1:1 analog with machine instructions. This is accomplished using mnemonics for the actual instructions, registers, or other resources. Examples include JMP and MULT for the CPU's jump and multiplication instructions. Unlike machine code, the CPU does not understand assembly code. You convert assembly code to machine code with the use of an assembler or a compiler, though we usually think of compilers in association with high-level programming language that are abstracted further from the CPU instructions.

Building a complete program involves writing source code for the program in either assembly or a higher level language like C++. The source code is assembled (for assembly code) or compiled (for higher level languages) to object code, and individual modules are linked together to become the machine code for the final program. In the case of very simple programs the linking step may not be needed. In other cases, such as with an IDE (integrated development environment) the linker and compiler may be invoked together. In other cases, a complicated make script or solution file may be used to tell the environment how to build the final application.

There are also interpreted languages that behave differently. Interpreted languages rely on the machine code of a special interpreter program. At the basic level, an interpreter parses the source code and immediately converts the commands to new machine code and executes them. Modern interpreters are now much more complicated: evaluating whole sections of source code at a time, caching and optimizing where possible, and handling complex memory management tasks.

One final type of program involves the use of a runtime-environment or virtual machine. In this situation, a program is first pre-compiled to a lower-level intermediate language or byte code. The byte code is then loaded by the virtual machine, which just-in-time compiles it to native code. The advantage here is the virtual machine can take advantage of optimizations available at the time the program runs and for that specific environment. A compiler belongs to the developer, and therefore must produce relatively generic (less-optimized) machine code that could run in many places. The runtime environment or virtual machine, however, is located on the end user's computer and therefore can take advantage of all the features provided by that system.

This is specific for each site. So if you type that once, you will only get through that site and all other sites will need a similar type-through.

It is also remembered for that site and you have to click on the padlock to reset it (so you can type it again):

Needless to say use of this "feature" is a bad idea and is unsafe - hence the name.

You should find out why the site is showing the error and/or stop using it until they fix it. HSTS specifically adds protections for bad certs to prevent you clicking through them. The fact it's needed suggests there is something wrong with the https connection - like the site or your connection to it has been hacked.

The chrome developers also do change this periodically. They changed it recently from badidea to thisisunsafe so everyone using badidea, suddenly stopped being able to use it. You should not depend on it. As Steffen pointed out in the comments below, it is available in the code should it change again though they now base64 encode it to make it more obscure. The last time they changed they put this comment in the commit:

Rotate the interstitial bypass keyword

The security interstitial bypass keyword hasn't changed in two years and awareness of the bypass has been increased in blogs and social media. Rotate the keyword to help prevent misuse.

I think the message from the Chrome team is clear - you should not use it. It would not surprise me if they removed it completely in future.

If you are using this when using a self-signed certificate for local testing then why not just add your self-signed certificate certificate to your computer's certificate store so you get a green padlock and do not have to type this? Note Chrome insists on a SAN field in certificates now so if just using the old subject field then even adding it to the certificate store will not result in a green padlock.

If you leave the certificate untrusted then certain things do not work. Caching for example is completely ignored for untrusted certificates. As is HTTP/2 Push.

HTTPS is here to stay and we need to get used to using it properly - and not bypassing the warnings with a hack that is liable to change and doesn't work the same as a full HTTPS solution.

Are there best practices with regards to the organisation of packages in Java and what goes in them?

Not really no. There are lots of ideas, and lots opinions, but real "best practice" is to use your common sense!

(Please read No best Practices for a perspective on "best practices" and the people who promote them.)

However, there is one principal that probably has broad acceptance. Your package structure should reflect your application's (informal) module structure, and you should aim to minimize (or ideally entirely avoid) any cyclic dependencies between modules.

(Cyclic dependencies between classes in a package / module are just fine, but inter-package cycles tend to make it hard understand your application's architecture, and can be a barrier to code reuse. In particular, if you use Maven you will find that cyclic inter-package / inter-module dependencies mean that the whole interconnected mess has to be one Maven artifact.)

I should also add that there is one widely accepted best practice for package names. And that is that your package names should start with your organization's domain name in reverse order. If you follow this rule, you reduce the likelihood of problems caused by your (full) class names clashing with other peoples'.

Most of the above mentioned solution didn't worked for me. However, below given solution works just fine:

<div class="fixed-bottom">...</div>

From your comment to gnibbler answer, i'd say you want a list of pairs of key-value sorted by value:

sorted(data.items(), key=lambda x:x[1])

And what about trying not to delete but hide that row?

I tried the lookup('pipe,'date') method and got trouble when I push the playbook to the tower. The tower is somehow using UTC timezone. All play executed as early as the + hours of my TZ will give me one day later of the actual date.

For example: if my TZ is Asia/Manila I supposed to have UTC+8. If I execute the playbook earlier than 8:00am in Ansible Tower, the date will follow to what was in UTC+0. It took me a while until I found this case. It let me use the date option '-d \"+8 hours\" +%F'. Now it gives me the exact date that I wanted.

Below is the variable I set in my playbook:

  vars:
    cur_target_wd: "{{ lookup('pipe','date -d \"+8 hours\" +%Y/%m-%b/%d-%a') }}"

That will give me the value of "cur_target_wd = 2020/05-May/28-Thu" even I run it earlier than 8:00am now.

If you have this :

a = [[1, 1], [2, 1],[3, 1]]

You can easily access this by using :

print(a[0][2])
a[0][1] = 7
print(a)

From http://www.quora.com/What-is-the-difference-between-compiled-and-interpreted-programming-languages

There is no difference, because “compiled programming language” and “interpreted programming language” aren’t meaningful concepts. Any programming language, and I really mean any, can be interpreted or compiled. Thus, interpretation and compilation are implementation techniques, not attributes of languages.

Interpretation is a technique whereby another program, the interpreter, performs operations on behalf of the program being interpreted in order to run it. If you can imagine reading a program and doing what it says to do step-by-step, say on a piece of scratch paper, that’s just what an interpreter does as well. A common reason to interpret a program is that interpreters are relatively easy to write. Another reason is that an interpreter can monitor what a program tries to do as it runs, to enforce a policy, say, for security.

Compilation is a technique whereby a program written in one language (the “source language”) is translated into a program in another language (the “object language”), which hopefully means the same thing as the original program. While doing the translation, it is common for the compiler to also try to transform the program in ways that will make the object program faster (without changing its meaning!). A common reason to compile a program is that there’s some good way to run programs in the object language quickly and without the overhead of interpreting the source language along the way.

You may have guessed, based on the above definitions, that these two implementation techniques are not mutually exclusive, and may even be complementary. Traditionally, the object language of a compiler was machine code or something similar, which refers to any number of programming languages understood by particular computer CPUs. The machine code would then run “on the metal” (though one might see, if one looks closely enough, that the “metal” works a lot like an interpreter). Today, however, it’s very common to use a compiler to generate object code that is meant to be interpreted—for example, this is how Java used to (and sometimes still does) work. There are compilers that translate other languages to JavaScript, which is then often run in a web browser, which might interpret the JavaScript, or compile it a virtual machine or native code. We also have interpreters for machine code, which can be used to emulate one kind of hardware on another. Or, one might use a compiler to generate object code that is then the source code for another compiler, which might even compile code in memory just in time for it to run, which in turn . . . you get the idea. There are many ways to combine these concepts.

There are multiple solution of this problem, in my case I changed my machine's password but forget to change it in the process model identity of Advance setting of that Application pool.

Later IISRESET did the trick for me.

It's actually not really clearly stated in the standard (RFC 3986) whether a percent-encoded version of . or .. is supposed to have the same this-folder/up-a-folder meaning as the unescaped version. Section 3.3 only talks about “The path segments . and ..”, without clarifying whether they match . and .. before or after pct-encoding.

Personally I find Firefox's interpretation that %2E does not mean . most practical, but unfortunately all the other browsers disagree. This would mean that you can't have a path component containing only . or ...

I think the only possible suggestion is “don't do that”! There are other path components that are troublesome too, typically due to server limitations: %2F, %00 and %5C sequences in paths may also be blocked by some web servers, and the empty path segment can also cause problems. So in general it's not possible to fit all possible byte sequences into a path component.

Cross-browser solution to checking CSS values without DOM manipulation:

function get_style_rule_value(selector, style)
{
 for (var i = 0; i < document.styleSheets.length; i++)
 {
  var mysheet = document.styleSheets[i];
  var myrules = mysheet.cssRules ? mysheet.cssRules : mysheet.rules;

  for (var j = 0; j < myrules.length; j++)
  {
   if (myrules[j].selectorText && myrules[j].selectorText.toLowerCase() === selector)
   {
    return myrules[j].style[style];
   }
  }
 }
};

Usage:

get_style_rule_value('.chart-color', 'backgroundColor')

Sanitized version (forces selector input to lowercase, and allows for use case without leading ".")

function get_style_rule_value(selector, style)
{
 var selector_compare=selector.toLowerCase();
 var selector_compare2= selector_compare.substr(0,1)==='.' ?  selector_compare.substr(1) : '.'+selector_compare;

 for (var i = 0; i < document.styleSheets.length; i++)
 {
  var mysheet = document.styleSheets[i];
  var myrules = mysheet.cssRules ? mysheet.cssRules : mysheet.rules;

  for (var j = 0; j < myrules.length; j++)
  {
    if (myrules[j].selectorText)
    {
     var check = myrules[j].selectorText.toLowerCase();
     switch (check)
     {
      case selector_compare  :
      case selector_compare2 : return myrules[j].style[style];
     }
    }
   }
  }
 }

What does

$ git config --get-regexp '^(remote|branch)\.'

returns (executed within your git repository) ?

Origin is just a default naming convention for referring to a remote Git repository.

If it does not refer to GitHub (but rather a path to your teammate repository, path which may no longer be valid or available), just add another origin, like in this Bloggitation entry

$ git remote add origin2 [email protected]:myLogin/myProject.git
$ git push origin2 master

(I would actually use the name 'github' rather than 'origin' or 'origin2')

Permission denied (publickey).
fatal: The remote end hung up unexpectedly

Check if your gitHub identity is correctly declared in your local Git repository, as mentioned in the GitHub Help guide. (both user.name and github.name -- and github.token)

Then, stonean blog suggests (as does Marcio Garcia):

$ cd ~/.ssh
$ ssh-add id_rsa

Aral Balkan adds: create a config file

The solution was to create a config file under ~/.ssh/ as outlined at the bottom of the OS X section of this page.

Here's the file I added, as per the instructions on the page, and my pushes started working again:

Host github.com
User git
Port 22
Hostname github.com
IdentityFile ~/.ssh/id_rsa
TCPKeepAlive yes
IdentitiesOnly yes

You can also post the result of

ssh -v [email protected]

to have more information as to why GitHub ssh connection rejects you.

Check also you did enter correctly your public key (it needs to end with '==').
Do not paste your private key, but your public one. A public key would look something like:

ssh-rsa AAAAB3<big string here>== [email protected] 

(Note: did you use a passphrase for your ssh keys ? It would be easier without a passphrase)

Check also the url used when pushing ([email protected]/..., not git://github.com/...)

Check that you do have a SSH Agent to use and cache your key.

Try this:

 $ ssh -i path/to/public/key [email protected]

If that works, then it means your key is not being sent to GitHub by your ssh client.

jeues answer helped me nothing :-( after hours I finally found the solution for my system and I think this will help other people too. I had to set the LD_LIBRARY_PATH like this:

   export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/

after that everything worked very well, even without any "-extension RANDR" switch.

I had the same problem, and I was using the following plugin for tests:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.9</version>
    <configuration>
        <useFile>true</useFile>
        <includes>
            <include>**/*Tests.java</include>
            <include>**/*Test.java</include>
        </includes>
        <excludes>
            <exclude>**/Abstract*.java</exclude>
        </excludes>
        <junitArtifactName>junit:junit</junitArtifactName>
        <parallel>methods</parallel>
        <threadCount>10</threadCount>
    </configuration>
</plugin>

The test were running fine in the IDE (eclipse sts), but failed when using command mvn test.

After a lot of trial and error, I figured the solution was to remove parallel testing, the following two lines from the plugin configuration above:

    <parallel>methods</parallel>
    <threadCount>10</threadCount>

Hope that this helps someone out!

As per your requirement, Thread.Sleep is perfectly fine to use because you are not sure when the data will be available so you might need to wait for the data to become available. I have slightly changed the logic of your function this might help you little further.

string SendCmd(string cmd, string ip, int port)
{
    var client = new TcpClient(ip, port);
    var data = Encoding.GetEncoding(1252).GetBytes(cmd);
    var stm = client.GetStream();
    stm.Write(data, 0, data.Length);
    byte[] resp = new byte[2048];
    var memStream = new MemoryStream();

    int bytes = 0;

    do
    {
        bytes = 0;
        while (!stm.DataAvailable)
            Thread.Sleep(20); // some delay
        bytes = stm.Read(resp, 0, resp.Length);
        memStream.Write(resp, 0, bytes);
    } 
    while (bytes > 0);

    return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}

Hope this helps!
