CPython (the classic and prevalent implementation of Python) can't have more than one thread executing Python bytecode at the same time. This means compute-bound programs will only use one core. I/O operations and computing happening inside C extensions (such as numpy) can operate simultaneously.

Other implementation of Python (such as Jython or PyPy) may behave differently, I'm less clear on their details.

The usual recommendation is to use many processes rather than many threads.

Just add this to your global CSS style:

a { cursor: pointer; }

This way you're not dependent on the browser default cursor style anymore.

NPM package libraries have a section in the package.json file named peerDependencies. For example; a library built in Angular 8, will usually list Angular 8 as a dependency. This is a true dependency for anyone running less than version 8. But for anyone running version 8, 9 or 10, it's questionable whether any concern should be pursued.

I have been safely ignoring these messages on Angular Updates, but then again we do have Unit and Cypress Tests!

What about this:

while ($row = mysql_fetch_array($result)) 
{
    $new_array[$row['id']]['id'] = $row['id'];
    $new_array[$row['id']]['link'] = $row['link'];
}

To retrieve link and id:

foreach($new_array as $array)
{       
   echo $array['id'].'<br />';
   echo $array['link'].'<br />';
}

In general it is safer to work on copies than on original data frames, except when you know that you won't be needing the original anymore and want to proceed with the manipulated version. Normally, you would still have some use for the original data frame to compare with the manipulated version, etc. Therefore, most people work on copies and merge at the end.

You can't do this with Html.ActionLink. You should use Url.RouteUrl and use the URL to construct the element you want.

The other answers are correct: You don't have a default value. However, you have another problem in your logic:

You read the same file twice. After reading it once, the cursor is at the end of the file. To solve this, you can do two things: Either open/close the file upon each function call:

def temp_sky(lreq, breq):
    with open("/home/path/to/file",'r') as tfile:
        # do your stuff

This hase the disadvantage of having to open the file each time. The better way would be:

tfile.seek(0)

You do this after your for line in tfile: loop. It resets the cursor to the beginning to the next call will start from there again.

I had log4j.properties in the correct place in the classpath and still got this warning with anything that used it directly. Code using log4j through commons-logging seemed to be fine for some reason.

If you have:

log4j.rootLogger=WARN

Change it to:

log4j.rootLogger=WARN, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.conversionPattern=%5p [%t] (%F:%L) - %m%n

According to http://logging.apache.org/log4j/1.2/manual.html:

The root logger is anonymous but can be accessed with the Logger.getRootLogger() method. There is no default appender attached to root.

What this means is that you need to specify some appender, any appender, to the root logger to get logging to happen.

Adding that console appender to the rootLogger gets this complaint to disappear.

Make sure you have the prerequisite, a JVM (http://wiki.eclipse.org/Eclipse/Installation#Install_a_JVM) installed.

This will be a JRE and JDK package.

There are a number of sources which includes: http://www.oracle.com/technetwork/java/javase/downloads/index.html.

var promise = $interval(function(){
    if($location.path() == '/landing'){
        $rootScope.$emit('testData',"test");
        $interval.cancel(promise);
    }
},2000);

I found AlecRust's solution quite helpful, but I add something to resolve one problem: When you click on a single accordion to expand it and then you click on the button to expand, they will all be opened. But, if you click again on the button to collapse, the single accordion expand before won't be collapse.

I've used imageButton, but you can also apply that logic to buttons.

/*** Expand all ***/
$(".expandAll").click(function (event) {
    $('.accordion .ui-accordion-header:not(.ui-state-active)').next().slideDown();

    return false;
});

/*** Collapse all ***/
$(".collapseAll").click(function (event) {
    $('.accordion').accordion({
        collapsible: true,
        active: false
    });

    $('.accordion .ui-accordion-header').next().slideUp();

    return false;
});

Also, if you have accordions inside an accordion and you want to expand all only on that second level, you can add a query:

/*** Expand all Second Level ***/
$(".expandAll").click(function (event) {
    $('.accordion .ui-accordion-header:not(.ui-state-active)').nextAll(':has(.accordion .ui-accordion-header)').slideDown();

    return false;
});

You can try this

set @duration= 112000
SELECT 
   "Time" = cast (@duration/3600 as varchar(3)) +'H'
         + Case 
       when ((@duration%3600 )/60)<10 then
                 '0'+ cast ((@duration%3600 )/60)as varchar(3))
       else 
               cast ((@duration/60) as varchar(3))
       End

I had the scenario like want to rename the folder and change the build output location, and used below code in the package.json with the latest version

"build": "react-scripts build && mv build ../my_bundles"

The bottom statement is equivalent to:

.half {
   flex-grow: 0;
   flex-shrink: 0;
   flex-basis: 50%;
}

Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.

Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.

I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)

Cookie

• is a small amount of data saved in the browser (client-side)

• can be set from PHP with setcookie and then will be sent to the client's browser (HTTP response header Set-cookie)

• can be set directly client-side in Javascript: document.cookie = 'foo=bar';

• if no expiration date is set, by default, it will expire when the browser is closed.
  Example: go on http://example.com, open the Console, do document.cookie = 'foo=bar';. Close the tab, reopen the same website, open the Console, do document.cookie: you will see foo=bar is still there. Now close the browser and reopen it, re-visit the same website, open the Console ; you will see document.cookie is empty.

• you can also set a precise expiration date other than "deleted when browser is closed".

• the cookies that are stored in the browser are sent to the server in the headers of every request of the same website (see Cookie). You can see this for example with Chrome by opening Developer tools > Network, click on the request, see Headers:

  

• can be read client-side with document.cookie

• can be read server-side with $_COOKIE['foo']

• Bonus: it can also be set/get with another language than PHP. Example in Python with "bottle" micro-framework (see also here):

  from bottle import get, run, request, response
  @get('/')
  def index():
      if request.get_cookie("visited"):
          return "Welcome back! Nice to see you again"
      else:
          response.set_cookie("visited", "yes")
          return "Hello there! Nice to meet you"
  run(host='localhost', port=8080, debug=True, reloader=True)
  

Session

• is some data relative to a browser session saved server-side

• each server-side language may implement it in a different way

• in PHP, when session_start(); is called:

  • a random ID is generated by the server, e.g. jo96fme9ko0f85cdglb3hl6ah6
  • a file is saved on the server, containing the data: e.g. /var/lib/php5/sess_jo96fme9ko0f85cdglb3hl6ah6

  • the session ID is sent to the client in the HTTP response headers, using the traditional cookie mechanism detailed above: Set-Cookie: PHPSESSID=jo96fme9ko0f85cdglb3hl6ah6; path=/:

    

    (it can also be be sent via the URL instead of cookie but not the default behaviour)

  • you can see the session ID on client-side with document.cookie:

    

• the PHPSESSID cookie is set with no expiration date, thus it will expire when the browser is closed. Thus "sessions" are not valid anymore when the browser is closed / reopened.

• can be set/read in PHP with $_SESSION

• the client-side does not see the session data but only the ID: do this in index.php:

  <?php
  session_start();
  $_SESSION["abc"]="def";
  ?>
  

  The only thing that is seen on client-side is (as mentioned above) the session ID:

  

• because of this, session is useful to store data that you don't want to be seen or modified by the client

• you can totally avoid using sessions if you want to use your own database + IDs and send an ID/token to the client with a traditional Cookie

adjust the background-position to move background images in different positions of the div

div { 
       background-image: url('image url')
       background-position: 0 -250px; 
    }

One thing I see here to optimize.

While I do agree that the balls hit when the distance is the sum of their radii one should never actually calculate this distance! Rather, calculate it's square and work with it that way. There's no reason for that expensive square root operation.

Also, once you have found a collision you have to continue to evaluate collisions until no more remain. The problem is that the first one might cause others that have to be resolved before you get an accurate picture. Consider what happens if the ball hits a ball at the edge? The second ball hits the edge and immediately rebounds into the first ball. If you bang into a pile of balls in the corner you could have quite a few collisions that have to be resolved before you can iterate the next cycle.

As for the O(n^2), all you can do is minimize the cost of rejecting ones that miss:

1) A ball that is not moving can't hit anything. If there are a reasonable number of balls lying around on the floor this could save a lot of tests. (Note that you must still check if something hit the stationary ball.)

2) Something that might be worth doing: Divide the screen into a number of zones but the lines should be fuzzy--balls at the edge of a zone are listed as being in all the relevant (could be 4) zones. I would use a 4x4 grid, store the zones as bits. If an AND of the zones of two balls zones returns zero, end of test.

3) As I mentioned, don't do the square root.

There's no direct equivalent of "friend" - the closest that's available (and it isn't very close) is InternalsVisibleTo. I've only ever used this attribute for testing - where it's very handy!

Example: To be placed in AssemblyInfo.cs

[assembly: InternalsVisibleTo("OtherAssembly")]

Open them from a new instance of Excel.

Sub Test()

    Dim xl As Excel.Application
    Set xl = CreateObject("Excel.Application")

    Dim w As Workbook
    Set w = xl.Workbooks.Add()

    MsgBox "Not visible yet..."
    xl.Visible = True

    w.Close False
    Set xl = Nothing

End Sub

You need to remember to clean up after you're done.

Call second ajax from 'complete'

Here is the example

   var dt='';
   $.ajax({
    type: "post",
    url: "ajax/example.php",
    data: 'page='+btn_page,
    success: function(data){
        dt=data;
        /*Do something*/
    },
    complete:function(){
        $.ajax({
           var a=dt; // This line shows error.
           type: "post",
           url: "example.php",
           data: 'page='+a,
           success: function(data){
              /*do some thing in second function*/
           },
       });
    }
});

If the first column is always the same size (including the spaces), then you can just take those characters (via LEFT) and clean up the spaces (with RTRIM):

SELECT RTRIM(LEFT(YourColumn, YourColumnSize))

Alternatively, you can extract the second (or third, etc.) column (using SUBSTRING):

SELECT RTRIM(SUBSTRING(YourColumn, PreviousColumnSizes, YourColumnSize))

One benefit of this approach (especially if YourColumn is the result of a computation) is that YourColumn is only specified once.

Some additional test-info on @Orwellophile code using a 17.9MB textfile.
Using the property values in the code-example "as is" will have a HUGE negative impact on performance, it takes 14.16 sec.

Setting the properties to the following do the same job at 3.91 sec (i.a. the archive will have the same container info which is: you can extract and test the archive with 7zip but there are no filename information)

Native 7zip 2 sec.

CoderPropID[] propIDs =  {
  //CoderPropID.DictionarySize,
  //CoderPropID.PosStateBits,
  //CoderPropID.LitContextBits,
  //CoderPropID.LitPosBits,
  //CoderPropID.Algorithm,
  //CoderPropID.NumFastBytes,
  //CoderPropID.MatchFinder,
  CoderPropID.EndMarker
};
object[] properties = {
  //(Int32)(dictionary),
  //(Int32)(posStateBits),
  //(Int32)(litContextBits),
  //(Int32)(litPosBits),
  //(Int32)(algorithm),
  //(Int32)(numFastBytes),
  //mf,
  eos
};

I did another test using native 7zip and a 1,2GB SQL backup file (.bak)
7zip (maximum compression): 1 minute
LZMA SDK (@Orwellophile with above property-setting): 12:26 min :-(
Outputfile roughly same size.

So I guess I'll myself will use a solution based on the c/c++ engine, i.a. either call the 7zip executable from c# or use squid-box/SevenZipSharp, which is a wrapper around the 7zip c/c++ dll file, and seems to be the newest fork of SevenZipSharp. Haven't tested the wrapper, but I hope is perform just as the native 7zip. But hopefully it will give the possibility to compress stream also which you obvious cannot if you call the exe directly. Otherwise I guess there isn't mush advantage over calling the exe. The wrapper have some additional dependencies so it will not make your published project "cleaner".

By the way it seems the .Net Core team consider implementing LZMA in the system.io class in .Core ver. 5, that would be great!

(I know this is kind of a comment and not an answer but to be able to provide the code snippet it couldn't be a comment)

git rev-parse --show-toplevel

could be enough if executed within a git repo.
From git rev-parse man page:

--show-toplevel

Show the absolute path of the top-level directory.

For older versions (before 1.7.x), the other options are listed in "Is there a way to get the git root directory in one command?":

git rev-parse --git-dir

That would give the path of the .git directory.

The OP mentions:

git rev-parse --show-prefix

which returns the local path under the git repo root. (empty if you are at the git repo root)

Note: for simply checking if one is in a git repo, I find the following command quite expressive:

git rev-parse --is-inside-work-tree

And yes, if you need to check if you are in a .git git-dir folder:

git rev-parse --is-inside-git-dir

The data variable contains a Buffer object. Convert it into ASCII encoding using the following syntax:

data.toString('ascii', 0, data.length)

Asynchronously:

fs.readFile('test.txt', 'utf8', function (error, data) {
    if (error) throw error;
    console.log(data.toString());
});

If you don't want to wrap a table under any div:

table{
  table-layout: fixed;
}
tbody{
      display: block;
    overflow: auto;
}

I was having issues because I updated my AdHoc provisioning profile with some new devices for use on TestFlight. Assumedly this is happening because Xcode has an old reference to your provisioning profile in either the codesigning build settings for the project or the targets. The way I fixed mine was to:

1. Go to both target build settings and project build settings, Under code signing change all the provisioning profiles to something else.
2. Go to devices/provisioning profiles in the Organizer delete the offending profiles, then click the refresh button in the bottom right.
3. Go back to to the target and project build settings and set your provisioning profiles to the appropriate (hopefully) newly refreshed provisioning profiles.

It may be a little late but you may use my library KResourceLoader to get a resource from your jar:

File resource = getResource("file.txt")

It is highly unlikely that adding NameVirtualHost *:443 is the right solution, because there are a limited number of situations in which it is possible to support name-based virtual hosts over SSL. Read this and this for some details (there may be better docs out there; these were just ones I found that discuss the issue in detail).

If you're running a relatively stock Apache configuration, you probably have this somewhere:

<VirtualHost _default_:443>

Your best bet is to either:

• Place your additional SSL configuration into this existing VirtualHost container, or
• Comment out this entire VirtualHost block and create a new one. Don't forget to include all the relevant SSL options.

Here's how to do it using default ACLs, at least under Linux.

First, you might need to enable ACL support on your filesystem. If you are using ext4 then it is already enabled. Other filesystems (e.g., ext3) need to be mounted with the acl option. In that case, add the option to your /etc/fstab. For example, if the directory is located on your root filesystem:

/dev/mapper/qz-root   /    ext3    errors=remount-ro,acl   0  1

Then remount it:

mount -oremount /

Now, use the following command to set the default ACL:

setfacl -dm u::rwx,g::rwx,o::r /shared/directory

All new files in /shared/directory should now get the desired permissions. Of course, it also depends on the application creating the file. For example, most files won't be executable by anyone from the start (depending on the mode argument to the open(2) or creat(2) call), just like when using umask. Some utilities like cp, tar, and rsync will try to preserve the permissions of the source file(s) which will mask out your default ACL if the source file was not group-writable.

Hope this helps!

WINDOWS 7

If there is anyone new reading this, make sure to simply try a clean install of mingw before any of this. It will save you sooooo much time if that is your problem.

I opened up wingw installer, selected every program for removal, apply changes (under installation tab, upper left corner), closed out, went back in and installed every file (in "Basic Setup" section) availible. after that eclipse worked fine using "MinGW GCC" toolchain when starting a new C++ project.

I hope this works for someone else. If not, I would do a reinstall of JDK (Java Developer's Kit) and ECLIPSE as well. I have a 64bit system but I could only get the 32bit versions of Eclipse and JDK to work together.

If the value is a file url like file://C:/whatever, use the Uri class to translate to a regular filename:

var localPath = (new Uri(urlStylePath)).AbsolutePath

In general, using the provided API is best practice.

Im using the following code in order to access generated find methods from my custom implementation. Getting the implementation through the bean factory prevents circular bean creation problems.

public class MyRepositoryImpl implements MyRepositoryExtensions, BeanFactoryAware {

    private BrandRepository myRepository;

    public MyBean findOne(int first, int second) {
        return myRepository.findOne(new Id(first, second));
    }

    public void setBeanFactory(BeanFactory beanFactory) throws BeansException {
        myRepository = beanFactory.getBean(MyRepository.class);
    }
}

Removing the .lock file and reinstalling did not solve the issue on my machine (Ubuntu 19.10). The problem was that after unexpected shutdown, the MongoDB sock does not belong to the MongoDB group and user anymore.

So, I follow the steps below:

1. cd /tmp
2. ls *.sock

3. Change the user:group permission:

   chown mongodb:mongodb <YOUR_SOCK>
   

4. sudo systemctl start mongod

5. sudo systemctl status mongod

One important reason for creating a DLL/LIB rather than just compiling the code into an executable is reuse and relocation. The average Java or .NET application (for example) will most likely use several 3rd party (or framework) libraries. It is much easier and faster to just compile against a pre-built library, rather than having to compile all of the 3rd party code into your application. Compiling your code into libraries also encourages good design practices, e.g. designing your classes to be used in different types of applications.

I met the problem too, and I found the way to set style programatically. Maybe you all need it, So I update there.

The third param of View constructor accepts a type of attr in your theme as the source code below:

public TextView(Context context, AttributeSet attrs) {
    this(context, attrs, com.android.internal.R.attr.textViewStyle);
}

So you must pass a type of R.attr.** rather than R.style.**

In my codes, I did following steps:

First, customize a customized attr to be used by themes in attr.xml.

<attr name="radio_button_style" format="reference" />

Second, specific your style in your used theme in style.xml.

 <style name="AppTheme" parent="android:Theme.Translucent">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    <item name="radio_button_style">@style/radioButtonStyle</item>
</style>
<style name="radioButtonStyle" parent="@android:style/Widget.CompoundButton.RadioButton">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">64dp</item>
    <item name="android:background">#000</item>
    <item name="android:button">@null</item>
    <item name="android:gravity">center</item>
    <item name="android:saveEnabled">false</item>
    <item name="android:textColor">@drawable/option_text_color</item>
    <item name="android:textSize">9sp</item>
</style>

At the end, use it!

            RadioButton radioButton = new RadioButton(mContext, null, R.attr.radio_button_style);

the view created programatically will use the specified style in your theme.

You can have a try, and hope it can work for you perfectly.

You can use the minus operator or Math.abs. These work for all negative integers EXCEPT for Integer.MIN_VALUE! If you do 0 - MIN_VALUE the answer is still MIN_VALUE.

Use ThenByDescending:

var hold = MyList.OrderBy(x => x.StartDate)
                 .ThenByDescending(x => x.EndDate)
                 .ToList();

You can also use query syntax and say:

var hold = (from x in MyList
           orderby x.StartDate, x.EndDate descending
           select x).ToList();

ThenByDescending is an extension method on IOrderedEnumerable which is what is returned by OrderBy. See also the related method ThenBy.

Here is a little extension I just put together.

public static class PositionsExtension
{
    public static Int32 Position<TSource>(this IEnumerable<TSource> source,
                                          Func<TSource, bool> predicate)
    {
        return Positions<TSource>(source, predicate).FirstOrDefault();
    }
    public static IEnumerable<Int32> Positions<TSource>(this IEnumerable<TSource> source, 
                                                        Func<TSource, bool> predicate)
    {
        if (typeof(TSource) is IDictionary)
        {
            throw new Exception("Dictionaries aren't supported");
        }

        if (source == null)
        {
            throw new ArgumentOutOfRangeException("source is null");
        }
        if (predicate == null)
        {
            throw new ArgumentOutOfRangeException("predicate is null");
        }
        var found = source.Where(predicate).First();
        var query = source.Select((item, index) => new
            {
                Found = ReferenceEquals(item, found),
                Index = index

            }).Where( it => it.Found).Select( it => it.Index);
        return query;
    }
}

Then you can call it like this.

IEnumerable<Int32> indicesWhereConditionIsMet = 
      ListItems.Positions(item => item == this);

Int32 firstWelcomeMessage ListItems.Position(msg =>               
      msg.WelcomeMessage.Contains("Hello"));

Be warned, each time the file is opened with this method the old data in the file is destroyed regardless of 'w+' or just 'w'.

import os

with open("file.txt", 'w+') as f:
    f.write("file is opened for business")

You can do with Very Simple Step

$(':radio[id=radio1]').change(function() {
   $("#yes").removeClass("none");
   $("#no").addClass("none");


});
$(':radio[id=radio2]').change(function() {
   $("#no").removeClass("none");
   $("#yes").addClass("none");

});

# indicates that the following line is a preprocessor directive and should be processed by the preprocessor before compilation by the compiler.

So, #include is a preprocessor directive that tells the preprocessor to include header files in the program.

< > indicate the start and end of the file name to be included.

iostream is a header file that contains functions for input/output operations (cin and cout).

Now to sum it up C++ to English translation of the command, #include <iostream> is:

Dear preprocessor, please include all the contents of the header file iostream at the very beginning of this program before compiler starts the actual compilation of the code.

I haven't found this to work on, say Application objects. I have however had success with

var serializer = new System.Web.Script.Serialization.JavaScriptSerializer();

string rval = serializer.Serialize(myAppObj);

do it like this

while true
do
  [ -f /tmp/list.txt ] && break
  sleep 2
done
ls -l /tmp/list.txt

Just use $interval

Here is your code modified. http://plnkr.co/edit/m7psQ5rwx4w1yAwAFdyr?p=preview

var app = angular.module('test', []);

app.controller('TestCtrl', function ($scope, $interval) {
   $scope.testValue = 0;

    $interval(function() {
        $scope.testValue++;
    }, 500);
});

I think the best way is to simply use:

window.open("yourURL", '_blank');

* flies away *

Just remove activation section, I don't know why -Pdev1 doesn't override default false activation. But if you omit this:

<activation> <activeByDefault>false</activeByDefault> </activation>

then your profile will be activated only after explicit declaration as -Pdev1

I also had the same problem. Then I installed the zlib, still the problem remained the same. Then I added the following lines in my .bashrc and it worked. You should replace the path with your zlib installation path. (I didn't have root privileges).

export PATH =$PATH:$HOME/Softwares/library/Zlib/zlib-1.2.11/

If you have even the relative pathname (in this case it appears to be ./) you can open files relative to your script file(s). I use Perl, but the same general solution can apply: I split the directory into an array of folders, then pop off the last element (the script), then push (or for you, append) on whatever I want, and then join them together again, and BAM! I have a working pathname that points to exactly where I expect it to point, relative or absolute.

Of course, there are better solutions, as posted. I just kind of like mine.

Base(Base::UPtr n):next(std::move(n)) {}

should be much better as

Base(Base::UPtr&& n):next(std::forward<Base::UPtr>(n)) {}

and

void setNext(Base::UPtr n)

should be

void setNext(Base::UPtr&& n)

with same body.

And ... what is evt in handle() ??

uint and ulong are the unsigned versions of int and long. That means they can't be negative. Instead they have a larger maximum value.

Type    Min                           Max                           CLS-compliant
int     -2,147,483,648                2,147,483,647                 Yes
uint    0                             4,294,967,295                 No
long    –9,223,372,036,854,775,808    9,223,372,036,854,775,807     Yes
ulong   0                             18,446,744,073,709,551,615    No

To write a literal unsigned int in your source code you can use the suffix u or U for example 123U.

You should not use uint and ulong in your public interface if you wish to be CLS-Compliant.

Read the documentation for more information:

• int
• uint
• long
• ulong

By the way, there is also short and ushort and byte and sbyte.

This should be consistent with how Q does it:

if(!Promise.allSettled) {
    Promise.allSettled = function (promises) {
        return Promise.all(promises.map(p => Promise.resolve(p).then(v => ({
            state: 'fulfilled',
            value: v,
        }), r => ({
            state: 'rejected',
            reason: r,
        }))));
    };
}

On most platforms, long and int are the same size (32 bits). Still, it does have its own format specifier:

long n;
unsigned long un;
printf("%ld", n); // signed
printf("%lu", un); // unsigned

For 64 bits, you'd want a long long:

long long n;
unsigned long long un;
printf("%lld", n); // signed
printf("%llu", un); // unsigned

Oh, and of course, it's different in Windows:

printf("%l64d", n); // signed
printf("%l64u", un); // unsigned

Frequently, when I'm printing 64-bit values, I find it helpful to print them in hex (usually with numbers that big, they are pointers or bit fields).

unsigned long long n;
printf("0x%016llX", n); // "0x" followed by "0-padded", "16 char wide", "long long", "HEX with 0-9A-F"

will print:

0x00000000DEADBEEF

Btw, "long" doesn't mean that much anymore (on mainstream x64). "int" is the platform default int size, typically 32 bits. "long" is usually the same size. However, they have different portability semantics on older platforms (and modern embedded platforms!). "long long" is a 64-bit number and usually what people meant to use unless they really really knew what they were doing editing a piece of x-platform portable code. Even then, they probably would have used a macro instead to capture the semantic meaning of the type (eg uint64_t).

char c;       // 8 bits
short s;      // 16 bits
int i;        // 32 bits (on modern platforms)
long l;       // 32 bits
long long ll; // 64 bits 

Back in the day, "int" was 16 bits. You'd think it would now be 64 bits, but no, that would have caused insane portability issues. Of course, even this is a simplification of the arcane and history-rich truth. See wiki:Integer

cURL is an option, using Ajax as well eventhough solving back-end problems with the front-end isn't so neat.

A very useful post about doing it without cURL is this one: http://netevil.org/blog/2006/nov/http-post-from-php-without-curl

The code to do this (untested, unimproved, from the blog post):

function do_post_request($url, $data, $optional_headers = null)
{
   $params = array('http' => array(
                'method' => 'POST',
                'content' => $data
             ));
   if ($optional_headers !== null) {
      $params['http']['header'] = $optional_headers;
   }
   $ctx = stream_context_create($params);
   $fp = @fopen($url, 'rb', false, $ctx);
   if (!$fp) {
      throw new Exception("Problem with $url, $php_errormsg");
   }
   $response = @stream_get_contents($fp);
   if ($response === false) {
      throw new Exception("Problem reading data from $url, $php_errormsg");
   }
   return $response;
}

Unless you're looking for something specific, you can already do Regular Expression matching using regular Javascript with strings.

For example, you can do matching using a string by something like this...

var phrase = "This is a phrase";
phrase = phrase.replace(/is/i, "is not");
alert(phrase);

Is there something you're looking for other than just Regular Expression matching in general?

In order to use word-wrap: break-word, you need to set a width (in px). For example:

div {
    width: 250px;
    word-wrap: break-word;
}

word-wrap is a CSS3 property, but it should work in all browsers, including IE 5.5-9.

There is a library for this BarCode PHP. You just need to include a few files:

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

You can generate many types of barcodes, namely 1D or 2D. Add the required library:

require_once('class/BCGcode39.barcode.php');

Generate the colours:

// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);

After you have added all the codes, you will get this way:

Example

Since several have asked for an example here is what I was able to do to get it done

require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');

require_once('class/BCGcode128.barcode.php');

header('Content-Type: image/png');

$color_white = new BCGColor(255, 255, 255);

$code = new BCGcode128();
$code->parse('HELLO');

$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);

$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);

If you want to actually create the image file so you can save it then change

$drawing = new BCGDrawing('', $color_white);

to

$drawing = new BCGDrawing('image.png', $color_white);

Your understanding is correct. However, if we walk through:

• (.*) will swallow the whole string;
• it will need to give back characters so that (\\d+) is satistifed (which is why 0 is captured, and not 3000);
• the last (.*) will then capture the rest.

I am not sure what the original intent of the author was, however.

tl;dr: JavaScript doesn't support associative arrays, therefore neither does JSON.

After all, it's JSON, not JSAAN. :)

So PHP has to convert your array into an object in order to encode into JSON.

I can't stress this advice enough: use a reset stylesheet, then set everything explicitly. It'll cut your cross-browser CSS development time in half.

Try Eric Meyer's reset.css.

As of October 3, 2012, a new "Elastic Beanstalk for Java with Apache Tomcat 7" Linux x64 AMI deployed with the Sample Application has the install here:

/etc/tomcat7/

The /etc/tomcat7/tomcat7.conf file has the following settings:

# Where your java installation lives
JAVA_HOME="/usr/lib/jvm/jre"

# Where your tomcat installation lives
CATALINA_BASE="/usr/share/tomcat7"
CATALINA_HOME="/usr/share/tomcat7"
JASPER_HOME="/usr/share/tomcat7"
CATALINA_TMPDIR="/var/cache/tomcat7/temp"

Do not hardcode path like //data/data/<Your-Application-Package-Name>/databases/<your-database-name>. Well it does work in most cases, but this one is not working in devices where device can support multiple users. The path can be like //data/user/10/<Your-Application-Package-Name>/databases/<your-database-name>. Possible solution to this is using context.getDatabasePath(<your-database-name>).

Here is the answer.

string result = String.Empty;

var list = new[]
{ 
    new { Number = 10, Name = "Smith" },
    new { Number = 10, Name = "John" } 
}.ToList();

foreach (var item in list)
{
    result += String.Format("Name={0}, Number={1}\n", item.Name, item.Number);
}

MessageBox.Show(result);

plt.box(False)
plt.xticks([])
plt.yticks([])
plt.savefig('fig.png')

should do the trick.

Try to do an UPDATE. If it doesn't modify any row that means it didn't exist, so do an insert. Obviously, you do this inside a transaction.

You can of course wrap this in a function if you don't want to put the extra code on the client side. You also need a loop for the very rare race condition in that thinking.

There's an example of this in the documentation: http://www.postgresql.org/docs/9.3/static/plpgsql-control-structures.html, example 40-2 right at the bottom.

That's usually the easiest way. You can do some magic with rules, but it's likely going to be a lot messier. I'd recommend the wrap-in-function approach over that any day.

This works for single row, or few row, values. If you're dealing with large amounts of rows for example from a subquery, you're best of splitting it into two queries, one for INSERT and one for UPDATE (as an appropriate join/subselect of course - no need to write your main filter twice)

you can use css property to hide style="display:none;"

<div style="display:none;">CREDITS_HERE</div>

You can also use this code to get LayoutInflater:

LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)

Efficient can mean throughput or latency.

For throughout, see the answer by Anders Cedronius, it’s a good one.

For lower latency, I would recommend this code:

uint32_t reverseBits( uint32_t x )
{
#if defined(__arm__) || defined(__aarch64__)
    __asm__( "rbit %0, %1" : "=r" ( x ) : "r" ( x ) );
    return x;
#endif
    // Flip pairwise
    x = ( ( x & 0x55555555 ) << 1 ) | ( ( x & 0xAAAAAAAA ) >> 1 );
    // Flip pairs
    x = ( ( x & 0x33333333 ) << 2 ) | ( ( x & 0xCCCCCCCC ) >> 2 );
    // Flip nibbles
    x = ( ( x & 0x0F0F0F0F ) << 4 ) | ( ( x & 0xF0F0F0F0 ) >> 4 );

    // Flip bytes. CPUs have an instruction for that, pretty fast one.
#ifdef _MSC_VER
    return _byteswap_ulong( x );
#elif defined(__INTEL_COMPILER)
    return (uint32_t)_bswap( (int)x );
#else
    // Assuming gcc or clang
    return __builtin_bswap32( x );
#endif
}

You're missing *s in the last two terms of your expression, so R is interpreting (e.g.) 0.207 (log(DIAM93))^2 as an attempt to call a function named 0.207 ...

For example:

> 1 + 2*(3)
[1] 7
> 1 + 2 (3)

Error: attempt to apply non-function

Your (unreproducible) expression should read:

censusdata_20$AGB93 = WD * exp(-1.239 + 1.980 * log (DIAM93) + 
                              0.207* (log(DIAM93))^2  -
                              0.0281*(log(DIAM93))^3)

Mathematica is the only computer system I know of that allows juxtaposition to be used for multiplication ...

to_char(tran_date, 'yyyy-mm-dd') = to_char(sysdate-1, 'yyyy-mm-dd')

What you're doing is creating a temporary. That temporary exists in a scope determined by the compiler, such that it's long enough to satisfy the requirements of where it's going.

As soon as the statement const char* cstr2 = ss.str().c_str(); is complete, the compiler sees no reason to keep the temporary string around, and it's destroyed, and thus your const char * is pointing to free'd memory.

Your statement string str(ss.str()); means that the temporary is used in the constructor for the string variable str that you've put on the local stack, and that stays around as long as you'd expect: until the end of the block, or function you've written. Therefore the const char * within is still good memory when you try the cout.

what does this error mean? Object reference not set to an instance of an object.

exactly what it says, you are trying to use a null object as if it was a properly referenced object.

Double-brace initialization is an unnecessary hack that can introduce memory leaks and other issues

There's no legitimate reason to use this "trick". Guava provides nice immutable collections that include both static factories and builders, allowing you to populate your collection where it's declared in a clean, readable, and safe syntax.

The example in the question becomes:

Set<String> flavors = ImmutableSet.of(
    "vanilla", "strawberry", "chocolate", "butter pecan");

Not only is this shorter and easier to read, but it avoids the numerous issues with the double-braced pattern described in other answers. Sure, it performs similarly to a directly-constructed HashMap, but it's dangerous and error-prone, and there are better options.

Any time you find yourself considering double-braced initialization you should re-examine your APIs or introduce new ones to properly address the issue, rather than take advantage of syntactic tricks.

Error-Prone now flags this anti-pattern.

I have found... margin: 0 auto; works for me. But I have also seen it NOT work due to the class being trumped by another specificity that had ... float:left; so watch for that you may need to add ... float:none; this worked in my case as I was coding a media query.

String#toLowerCase and String#toUpperCase are the methods you need.

Instead of strtotime you should use DateTime with PHP. You can also regard the timezone this way:

$dt = DateTime::createFromFormat('Y-m-d H:i:s', $mysqltime, new DateTimeZone('Europe/Berlin'));
$unix_timestamp = $dt->getTimestamp();

$mysqltime is of type MySQL Datetime, e. g. 2018-02-26 07:53:00.

To disable Screen Capture:

Add following line of code in onCreate() method:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE,
                           WindowManager.LayoutParams.FLAG_SECURE);

To enable Screen Capture:

Find for LayoutParams.FLAG_SECURE and remove the line of code.

Here's another way of attaching the event based on W3C DOM Level 2 Events Specification:

  transport_select.addEventListener(
     'change',
     function() { toggleSelect(this.id); },

  );

Above answer didn't work for me. Just try to run your command with --unsafe-perm.

e.g

npm install -g node@latest --unsafe-perm

This seems to solve the problem.

In PostgreSQL 9.6, there's a new option idle_in_transaction_session_timeout which should accomplish what you describe. You can set it using the SET command, e.g.:

SET SESSION idle_in_transaction_session_timeout = '5min';

Starting from pandas 0.20 ix is deprecated. The right way is to use df.loc

here is a working example

>>> import pandas as pd 
>>> import numpy as np 
>>> df = pd.DataFrame({"A":[0,1,0], "B":[2,0,5]}, columns=list('AB'))
>>> df.loc[df.A == 0, 'B'] = np.nan
>>> df
   A   B
0  0 NaN
1  1   0
2  0 NaN
>>> 

Explanation:

As explained in the doc here, .loc is primarily label based, but may also be used with a boolean array.

So, what we are doing above is applying df.loc[row_index, column_index] by:

• Exploiting the fact that loc can take a boolean array as a mask that tells pandas which subset of rows we want to change in row_index
• Exploiting the fact loc is also label based to select the column using the label 'B' in the column_index

We can use logical, condition or any operation that returns a series of booleans to construct the array of booleans. In the above example, we want any rows that contain a 0, for that we can use df.A == 0, as you can see in the example below, this returns a series of booleans.

>>> df = pd.DataFrame({"A":[0,1,0], "B":[2,0,5]}, columns=list('AB'))
>>> df 
   A  B
0  0  2
1  1  0
2  0  5
>>> df.A == 0 
0     True
1    False
2     True
Name: A, dtype: bool
>>> 

Then, we use the above array of booleans to select and modify the necessary rows:

>>> df.loc[df.A == 0, 'B'] = np.nan
>>> df
   A   B
0  0 NaN
1  1   0
2  0 NaN

I get very nervous when I see people using very large rule sets (e.g., on the order of thousands of rules in a single rule set). This often happens when the rules engine is a singleton sitting in the center of the enterprise in the hope that keeping rules DRY will make them accessible to many apps that require them. I would defy anyone to tell me that a Rete rules engine with that many rules is well-understood. I'm not aware of any tools that can check to ensure that conflicts don't exist.

I think partitioning rules sets to keep them small is a better option. Aspects can be a way to share a common rule set among many objects.

I prefer a simpler, more data driven approach wherever possible.

>>> x = "2342.34"
>>> float(x)
2342.3400000000001

There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).

setSize() or setBounds() can be used when no layout manager is being used.

However, if you are using a layout manager you can provide hints to the layout manager using the setXXXSize() methods like setPreferredSize() and setMinimumSize() etc.

And be sure that the component's container uses a layout manager that respects the requested size. The FlowLayout, GridBagLayout, and SpringLayout managers use the component's preferred size (the latter two depending on the constraints you set), but BorderLayout and GridLayout usually don't.If you specify new size hints for a component that's already visible, you need to invoke the revalidate method on it to make sure that its containment hierarchy is laid out again. Then invoke the repaint method.

You need to put Anaconda.sh to your /home/, then run it to install. After that, you can runexport PATH=~/anaconda3/bin:$PATH . Remark: do not run Anaconda.sh in download/ directily!!!!!

Just to add this to the list:

Uri.EscapeUriString("Hi there+Hello there") // Hi%20there+Hello%20there
Uri.EscapeDataString("Hi there+Hello there") // Hi%20there%2BHello%20there

See https://stackoverflow.com/a/34189188/98491

Usually you want to use EscapeDataString which does it right.

cp -r ./SourceFolder ./DestFolder

I ran into the same situation where commands such as git diff origin or git diff origin master produced the error reported in the question, namely Fatal: ambiguous argument...

To resolve the situation, I ran the command

git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/master

to set refs/remotes/origin/HEAD to point to the origin/master branch.

Before running this command, the output of git branch -a was:

* master
  remotes/origin/master

After running the command, the error no longer happened and the output of git branch -a was:

* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

(Other answers have already identified that the source of the error is HEAD not being set for origin. But I thought it helpful to provide a command which may be used to fix the error in question, although it may be obvious to some users.)

Additional information:

For anybody inclined to experiment and go back and forth between setting and unsetting refs/remotes/origin/HEAD, here are some examples.

To unset:
git remote set-head origin --delete

To set:
(additional ways, besides the way shown at the start of this answer)
git remote set-head origin master to set origin/head explicitly
OR
git remote set-head origin --auto to query the remote and automatically set origin/HEAD to the remote's current branch.

In Robins's answer ends-with is not supported in xpath 1.0 too.. Only starts-with is supported... So if your condition is not very specific..You can Use like this which worked for me

//*[starts-with(@id,'sometext') and contains(@name,'_text')]`\

try this

<?php
$str = "\x8F!!!";

// Outputs an empty string
echo htmlentities($str, ENT_QUOTES, "UTF-8");

// Outputs "!!!"
echo htmlentities($str, ENT_QUOTES | ENT_IGNORE, "UTF-8");
?>

Most devices have some form of emulated storage. if they support sd cards they are usually mounted to /sdcard (or some variation of that name) which is usually symlinked to to a directory in /storage like /storage/sdcard0 or /storage/0 sometimes the emulated storage is mounted to /sdcard and the actual path is something like /storage/emulated/legacy. You should be able to use to get the downloads directory. You are best off using the api calls to get directories. Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);

Since the filesystems and sdcard support varies among devices.

see similar question for more info how to access downloads folder in android?

Usually the DownloadManager handles downloads and the files are then accessed by requesting the file's uri fromthe download manager using a file id to get where file was places which would usually be somewhere in the sdcard/ real or emulated since apps can only read data from certain places on the filesystem outside of their data directory like the sdcard

Use the "containment" option:

jQuery UI API - Draggable Widget - containment

The documentation says it only accepts the values: 'parent', 'document', 'window', [x1, y1, x2, y2] but I seem to remember it will accept a selector such as '#container' too.

Little bit more complex data, mix of @Laran's and @Nisal Gunawardana's answers

[ 
   {  
       "foodItemsList":[
    {
       "id":7,
       "price":240,
       "quantity":1
                },
               { 
                "id":8,
                "quantity":1
               }],
        "price":340,
        "customer_id":1
   },
   {   
      "foodItemsList":[
    {
       "id":7,
       "quantity":1
    },
    { 
        "id":8,
        "quantity":1
    }],
    "customer_id":2
   }
]

The validation rule will be

 return [
            '*.customer_id' => 'required|numeric|exists:customers,id',
            '*.foodItemsList.*.id' => 'required|exists:food_items,id',
            '*.foodItemsList.*.quantity' => 'required|numeric',
        ];

I would suggest using implode/explode with a character that you know will not be contained in any of the individual array items. Then store it in SQL as a string.

Sure you just need to setup a local web server. Check out XAMPP: http://www.apachefriends.org/en/xampp.html

That will get you up and running in about 10 minutes.

There is now a way to run php locally without installing a server: https://stackoverflow.com/a/21872484/672229

Yes but the files need to be processed. For example you can install test servers like mamp / lamp / wamp depending on your plateform.

Basically you need apache / php running.

We've had similar problem and it was not enough to only remove commit and force push to GitLab.
It was still available in GitLab interface using url:

https://gitlab.example.com/<group>/<project>/commit/<commit hash>

We've had to remove project from GitLab and recreate it to get rid of this commit in GitLab UI.

Why is it that you need to place columns you create yourself (for example "select 1 as number") after HAVING and not WHERE in MySQL?

WHERE is applied before GROUP BY, HAVING is applied after (and can filter on aggregates).

In general, you can reference aliases in neither of these clauses, but MySQL allows referencing SELECT level aliases in GROUP BY, ORDER BY and HAVING.

And are there any downsides instead of doing "WHERE 1" (writing the whole definition instead of a column name)

If your calculated expression does not contain any aggregates, putting it into the WHERE clause will most probably be more efficient.

I just installed WAMP 3 on Windows 10 and had this issue.

I had to go to C:\wamp64\bin\php\php7.0.0\ and copy the php.ini file to C:\wamp64\bin\apache\apache2.4.17\bin\

Then I restarted WAMP, and was finally able to access my phpMyAdmin file.

Note: this is probably not the correct way to do this because now there are 2 php.ini files. There is probably a setting in an Apache file that points to the php.ini file, but I haven't seen that yet. I will update this if I find it.

i used this test to detect the scroll reached the bottom: event.target.scrollTop === event.target.scrollHeight - event.target.offsetHeight

You can use Object.values([]), you might need this polyfill if you don't already:

const objectToValuesPolyfill = (object) => {
  return Object.keys(object).map(key => object[key]);
};
Object.values = Object.values || objectToValuesPolyfill;

https://stackoverflow.com/a/54822153/846348

Then you can just do:

var object = {1: 'hello', 2: 'world'};
var array = Object.values(object);

Just remember that arrays in js can only use numerical keys so if you used something else in the object then those will become `0,1,2...x``

It can be useful to remove duplicates for example if you have a unique key.

var obj = {};
object[uniqueKey] = '...';

If you have already installed 2.2.5 and set as current ruby version, but still showing the same error even if the Ruby version 2.3.0 is not even installed, then just install the bundler.

gem install bundler

and then:

bundle install

I used builder in home-grown messaging library. The library core was receiving data from the wire, collecting it with Builder instance, then, once Builder decided it've got everything it needed to create a Message instance, Builder.GetMessage() was constructing a message instance using the data collected from the wire.

Not a prefect solution but if your happy with having the starting string as just a place holder you can add place holder spring value ("Day_of_Work_Out")

  @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            String name = (String) parent.getItemAtPosition(position);
            if (name.equals("Day_of_Work_Out")) {

            }else {

                workOutD = name;
                Intent intent = new Intent();
                workOutNam = workOutName.getText().toString();

                if (workOutNam == null) {

                    startActivity(intent);
                    Log.i("NewWorkOutActivity","Name is null");

                }else {
                    Log.i("NewWorkOutActivity","Name Not null");
                    Toast.makeText(NewWorkOutActivity.this, "Please Select a Day", Toast.LENGTH_LONG).show();
                }


            }
        }

You have to change the file from .html to .php.

and add this following line

header('Content-Type: text/html; charset=utf-8');

I changed the output path of the service. it should be inside bin folder of the service project. Once I put the output path back to bin, it worked.

Download Git on Msys. Then:

git clone git://project.url.here

Since localStorage is a global object, you can add a watch in the dev tools. Just enter the dev tools, goto "watch", click on "Click to add..." and type in "localStorage".

I experienced this today. The value in Config was the updated one but the application would return the older value, stop and starting the solution did nothing.

So I cleared the .Net Temp folder.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files

It shouldn't create bugs but to be safe close your solution down first. Clear the Temporary ASP.NET Files then load up your solution.

My issue was sorted.

If you have access to a console in the context you are investigating, you can determine which version you are running by printing the value of the global constant RUBY_VERSION.

Like explained in other answers you need to provide a comparison function. If you would like to keep the definition of that function close to the sort call (e.g. if it only makes sense for this sort) you can define it right there with boost::lambda. Use boost::lambda::bind to call the member function.

To e.g. sort by member variable or function data1:

#include <algorithm>
#include <vector>
#include <boost/lambda/bind.hpp>
#include <boost/lambda/lambda.hpp>
using boost::lambda::bind;
using boost::lambda::_1;
using boost::lambda::_2;

std::vector<myclass> object(10000);
std::sort(object.begin(), object.end(),
    bind(&myclass::data1, _1) < bind(&myclass::data1, _2));

I've found this easy solution

To convert from bitmap to Base64 use this method.

private String convertBitmapToBase64(Bitmap bitmap) {
    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream);
    byte[] byteArray = byteArrayOutputStream .toByteArray();
    return Base64.encodeToString(byteArray, Base64.DEFAULT);
}

To convert from Base64 to bitmap OR revert.

private Bitmap convertBase64ToBitmap(String b64) {
    byte[] imageAsBytes = Base64.decode(b64.getBytes(), Base64.DEFAULT);
    return BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length);
}

This might help

lsof -n -i4TCP:8080 

The PID is the second field in the output.

Or try:

lsof -i -P

I guess this is what you want:

l  = range(100)  
index = 0                       
for i in l:                         
    print i,              
    try:
        print l.pop(index+1),                  
        print l.pop(index+1)
    except:
        pass
    index += 1

It is quite handy to code when the number of item to be popped is a run time decision. But it runs with very a bad efficiency and the code is hard to maintain.

You should use openssl_encrypt() function.

If copying to/from your desktop machine, use WinSCP, or if on Linux, Nautilus supports SCP via the Connect To Server option.

scp can only copy files to a machine running sshd, hence you need to run the client software on the remote machine from the one you are running scp on.

If copying on the command line, use:

# copy from local machine to remote machine
scp localfile user@host:/path/to/whereyouwant/thefile

or

# copy from remote machine to local machine
scp user@host:/path/to/remotefile localfile

axios.put(url,{body},{headers:{}})

example:

}

axios.put('https://api.xxx.net/xx', body, {headers: api})

Update: the answer has been fixed.

I had the same issue and the following seemed to have addressed the issue.

a) Updated to latest version 1.3.5 and re-enabled all the diagnosis settings.

I was still getting the messages

b) Added the vendor folder with the dependent libraries to the workspace

This seems to have solved the problem.

i have one trick :

you can do this to prevent doubly encode. Every time first decode then again encode;

$string = urldecode($string);

Then do again

$string = urlencode($string);

Performing this way we can avoid double encode :)

Here are screenshots for SQL Server 2008 R2, using SSRS Report Designer in Visual Studio 2010.

I have done screenshots as some of the dialogs are not easy to find.

1: Add the group

2: Specify the field you want to group on

3: Now click on the group in the 'Row Groups' selector, directly below the report designer

4: F4 to select property pane; expand 'Group' and set Group > PageBreak > BreakLocation = 'Between', then enter the expression you want for Group > PageName

5: Here is an example expression

Here is the result of the report exported to Excel, with tabs named according to the PageName expression

If an Object variable is null, one cannot call an equals() method upon it, thus an object reference check of null is proper.

Because although the Java language doesn't use it, JVM bytecode does.

How did you pass object to method?

Are you doing new inside that method for object? If so, you have to use ref in method.

Following link give you better idea.

You only need to worry about using physically contiguous memory if the buffer will be accessed by a DMA device on a physically addressed bus (like PCI). The trouble is that many system calls have no way to know whether their buffer will eventually be passed to a DMA device: once you pass the buffer to another kernel subsystem, you really cannot know where it is going to go. Even if the kernel does not use the buffer for DMA today, a future development might do so.

vmalloc is often slower than kmalloc, because it may have to remap the buffer space into a virtually contiguous range. kmalloc never remaps, though if not called with GFP_ATOMIC kmalloc can block.

kmalloc is limited in the size of buffer it can provide: 128 KBytes^*). If you need a really big buffer, you have to use vmalloc or some other mechanism like reserving high memory at boot.

^*) This was true of earlier kernels. On recent kernels (I tested this on 2.6.33.2), max size of a single kmalloc is up to 4 MB! (I wrote a fairly detailed post on this.) — kaiwan

For a system call you don't need to pass GFP_ATOMIC to kmalloc(), you can use GFP_KERNEL. You're not an interrupt handler: the application code enters the kernel context by means of a trap, it is not an interrupt.

I have also been suffering from this problem, but finally got the solution, Initially directly the load the iframe url in browser like small popup then only access the session values inside the iframe.

Perhaps you could try ([^ ]+) .*, which should give you everything to the first blank in your first group.

You have to construct a new string out of a byte array. The first element in your byteArray should be 0x63. If you want to add any more letters, make the byteArray longer and add them to the next indices.

byte[] byteArray = new byte[1];
byteArray[0] = 0x63;

try {
    System.out.println("string " + new String(byteArray, "US-ASCII"));
} catch (UnsupportedEncodingException e) {
    // TODO: Handle exception.
    e.printStackTrace();
}

Note that specifying the encoding will eventually throw an UnsupportedEncodingException and you must handle that accordingly.

We've been working on a similar issue at work today, trying to figure out how to make a dropdown div disappear when it is clicked off of. Ours is slightly different than the initial poster's question because we didn't want to click away from a different component or directive, but merely outside of the particular div.

We ended up solving it by using the (window:mouseup) event handler.

Steps:
1.) We gave the entire dropdown menu div a unique class name.

2.) On the inner dropdown menu itself (the only portion that we wanted clicks to NOT close the menu), we added a (window:mouseup) event handler and passed in the $event.

NOTE: It could not be done with a typical "click" handler because this conflicted with the parent click handler.

3.) In our controller, we created the method that we wanted to be called on the click out event, and we use the event.closest (docs here) to find out if the clicked spot is within our targeted-class div.

 autoCloseForDropdownCars(event) {_x000D_
        var target = event.target;_x000D_
        if (!target.closest(".DropdownCars")) { _x000D_
            // do whatever you want here_x000D_
        }_x000D_
    }

 <div class="DropdownCars">_x000D_
   <span (click)="toggleDropdown(dropdownTypes.Cars)" class="searchBarPlaceholder">Cars</span>_x000D_
   <div class="criteriaDropdown" (window:mouseup)="autoCloseForDropdownCars($event)" *ngIf="isDropdownShown(dropdownTypes.Cars)">_x000D_
   </div>_x000D_
</div>

Presumably this would work:

IF(compliment = 'set' OR compliment = 'Y' OR compliment = 1, 'Y', 'N') AS customer_compliment

You have basically 2 options:

----Option 1

SELECT DISTINCT so.name
FROM syscomments sc
INNER JOIN sysobjects so ON sc.id=so.id
WHERE sc.TEXT LIKE '%tablename%'

----Option 2

SELECT DISTINCT o.name, o.xtype
FROM syscomments c
INNER JOIN sysobjects o ON c.id=o.id
WHERE c.TEXT LIKE '%tablename%'

These 2 queries will get you all the stored procedures that are referring the table you desire. This query relies on 2 sys tables which are sysobjects and syscomments. The sysobjects is where all of your DB object names are stored this includes the stored procedures.

The syscomments contains the text for all of your procedures.

If you query: SELECT * FROM syscomments

You'll have a table containing the id which is the mapping to the sysobjects table with the text contained in the stored procedures as the last column.

You can find your sample code completely here: http://www.java2s.com/Code/Java/Hibernate/OneToManyMappingbasedonSet.htm

Have a look and check the differences. specially the even_id in :

<set name="attendees" cascade="all">
    <key column="event_id"/>
    <one-to-many class="Attendee"/>
</set> 

You can try the code below:

# Load the packages required to read XML files.
library("XML")
library("methods")

# Convert the input xml file to a data frame.
xmldataframe <- xmlToDataFrame("input.xml")
print(xmldataframe)

/***Your Code***/
public void paintComponent(Graphics g){
/***Your Code***/
    g.setColor(Color.RED);
    g.fillOval(50,50,20,20);
}

g.fillOval(x-axis,y-axis,width,height);

At startup pass this -Dname=value

and then in your code you should use

value=System.getProperty("name");

to get that value

Here is my trick:

public class Main {

    public static void main(String[] args) throws Exception {

        System.out.println(Main.<String> getClazz());

    }

    static <T> Class getClazz(T... param) {

        return param.getClass().getComponentType();
    }

}

This is super old, but I figured I'd add my 2c. DATE_FORMAT does indeed return a string, but I was looking for the CAST function, in the situation that I already had a datetime string in the database and needed to pattern match against it:

http://dev.mysql.com/doc/refman/5.0/en/cast-functions.html

In this case, you'd use:

CAST(date_value AS char)

This answers a slightly different question, but the question title seems ambiguous enough that this might help someone searching.

This might help to understand what is recorded at what level Loggers may be assigned levels. Levels are instances of the log4net.Core.Level class. The following levels are defined in order of increasing severity - Log Level.

Agile is mostly used technique in project development.In agile technology peoples are switches from one technology to other ..Main purpose is to remove dependancy. Like Peoples shifted from production to development,and development to testing. Thats why dependancy will remove on a single team or person..

Great answers, but you could just open the command prompt and type in

 SET PATH=C:\Program Files\Nodejs;%PATH%

I had the same error after converting my project to Kotlin. My problem was that my jre location was changed to an invalid path during the process (I wonder why this could happen... made me waste time). Fixed it by doing this:

File > Project Structure > SDK Location 

Unchecked the Use embedded JDK option, which was pointing to an old JDK installation, and selected the correct one:

/home/my_user/jdk1.8.0_101

After changing this, the error disappeared

And for now, here is https://github.com/google/go-cmp which

is intended to be a more powerful and safer alternative to reflect.DeepEqual for comparing whether two values are semantically equal.

package main

    "github.com/google/go-cmp/cmp"
)

func main() {
    a := []byte{1, 2, 3}
    b := []byte{1, 2, 3}

    fmt.Println(cmp.Equal(a, b)) // true
}

https://support.procore.com/faq/what-is-the-difference-between-sp-and-idp-initiated-sso

There is much more to this but this is a high level overview on which is which.

Procore supports both SP- and IdP-initiated SSO:

Identity Provider Initiated (IdP-initiated) SSO. With this option, your end users must log into your Identity Provider's SSO page (e.g., Okta, OneLogin, or Microsoft Azure AD) and then click an icon to log into and open the Procore web application. To configure this solution, see Configure IdP-Initiated SSO for Microsoft Azure AD, Configure Procore for IdP-Initated Okta SSO, or Configure IdP-Initiated SSO for OneLogin. OR Service Provider Initiated (SP-initiated) SSO. Referred to as Procore-initiated SSO, this option gives your end users the ability to sign into the Procore Login page and then sends an authorization request to the Identify Provider (e.g., Okta, OneLogin, or Microsoft Azure AD). Once the IdP authenticates the user's identify, the user is logged into Procore. To configure this solution, see Configure Procore-Initiated SSO for Microsoft Azure Active Directory, Configure Procore-Initiated SSO for Okta, or Configure Procore-Initiated SSO for OneLogin.

Use this command to add job

crontab -e

In this format:

The easiest way to do it is to link the CSV-file into the Access database as a table. Then you can work on this table as if it was an ordinary access table, for instance by creating an appropriate query based on this table that returns exactly what you want.

You can link the table either manually or with VBA like this

DoCmd.TransferText TransferType:=acLinkDelim, TableName:="tblImport", _
    FileName:="C:\MyData.csv", HasFieldNames:=true

UPDATE

Dim db As DAO.Database

' Re-link the CSV Table
Set db = CurrentDb
On Error Resume Next:   db.TableDefs.Delete "tblImport":   On Error GoTo 0
db.TableDefs.Refresh
DoCmd.TransferText TransferType:=acLinkDelim, TableName:="tblImport", _
    FileName:="C:\MyData.csv", HasFieldNames:=true
db.TableDefs.Refresh

' Perform the import
db.Execute "INSERT INTO someTable SELECT col1, col2, ... FROM tblImport " _
   & "WHERE NOT F1 IN ('A1', 'A2', 'A3')"
db.Close:   Set db = Nothing

With the following command:

:%s/^M$//g

To get the ^M to appear, type CtrlV and then CtrlM. CtrlV tells Vim to take the next character entered literally.

I did this with anaconda navigator. I installed anaconda navigator and created two different development environments with different python versions

I think it is a better idea to start working with a raw data and then translate it to DOM (document object model)

I would suggest you to work with array of objects and then output it to the DOM in order to accomplish your task.

You can see working example of following code at http://www.softxml.com/stackoverflow/shoppingCart.htm

You can try following approach:

//create array that will hold all ordered products
    var shoppingCart = [];

    //this function manipulates DOM and displays content of our shopping cart
    function displayShoppingCart(){
        var orderedProductsTblBody=document.getElementById("orderedProductsTblBody");
        //ensure we delete all previously added rows from ordered products table
        while(orderedProductsTblBody.rows.length>0) {
            orderedProductsTblBody.deleteRow(0);
        }

        //variable to hold total price of shopping cart
        var cart_total_price=0;
        //iterate over array of objects
        for(var product in shoppingCart){
            //add new row      
            var row=orderedProductsTblBody.insertRow();
            //create three cells for product properties 
            var cellName = row.insertCell(0);
            var cellDescription = row.insertCell(1);
            var cellPrice = row.insertCell(2);
            cellPrice.align="right";
            //fill cells with values from current product object of our array
            cellName.innerHTML = shoppingCart[product].Name;
            cellDescription.innerHTML = shoppingCart[product].Description;
            cellPrice.innerHTML = shoppingCart[product].Price;
            cart_total_price+=shoppingCart[product].Price;
        }
        //fill total cost of our shopping cart 
        document.getElementById("cart_total").innerHTML=cart_total_price;
    }


    function AddtoCart(name,description,price){
       //Below we create JavaScript Object that will hold three properties you have mentioned:    Name,Description and Price
       var singleProduct = {};
       //Fill the product object with data
       singleProduct.Name=name;
       singleProduct.Description=description;
       singleProduct.Price=price;
       //Add newly created product to our shopping cart 
       shoppingCart.push(singleProduct);
       //call display function to show on screen
       displayShoppingCart();

    }  


    //Add some products to our shopping cart via code or you can create a button with onclick event
    //AddtoCart("Table","Big red table",50);
    //AddtoCart("Door","Big yellow door",150);
    //AddtoCart("Car","Ferrari S23",150000);

Hope you will find it useful.

I understand your frustration the " Graphics view widget" is not the best way to do this, yes it can be done, but it's almost exactly the same as using a label ( for what you want any way) now all the ways listed do work but...

For you and any one else that may come across this question he easiest way to do it ( what you're asking any way ) is this.

QPixmap pix("Path\\path\\entername.jpeg");
    ui->label->setPixmap(pix);

}

To do this, you can reset you local git repository to the first commit hashtag, so all your changes after that commit will be unstaged, then you can commit with --amend option.

git reset your-first-commit-hashtag
git add .
git commit --amend

And then edit the first commit nam if needed and save file.

Let's assume you want to overwrite the same file:

import json

with open('data.json', 'r') as data_file:
    data = json.load(data_file)

for element in data:
    element.pop('hours', None)

with open('data.json', 'w') as data_file:
    data = json.dump(data, data_file)

dict.pop(<key>, not_found=None) is probably what you where looking for, if I understood your requirements. Because it will remove the hours key if present and will not fail if not present.

However I am not sure I understand why it makes a difference to you whether the hours key contains some days or not, because you just want to get rid of the whole key / value pair, right?

Now, if you really want to use del instead of pop, here is how you could make your code work:

import json

with open('data.json') as data_file:
    data = json.load(data_file)

for element in data:
    if 'hours' in element:
        del element['hours']

with open('data.json', 'w') as data_file:
    data = json.dump(data, data_file)

EDIT So, as you can see, I added the code to write the data back to the file. If you want to write it to another file, just change the filename in the second open statement.

I had to change the indentation, as you might have noticed, so that the file has been closed during the data cleanup phase and can be overwritten at the end.

with is what is called a context manager, whatever it provides (here the data_file file descriptor) is available ONLY within that context. It means that as soon as the indentation of the with block ends, the file gets closed and the context ends, along with the file descriptor which becomes invalid / obsolete.

Without doing this, you wouldn't be able to open the file in write mode and get a new file descriptor to write into.

I hope it's clear enough...

SECOND EDIT

This time, it seems clear that you need to do this:

with open('dest_file.json', 'w') as dest_file:
    with open('source_file.json', 'r') as source_file:
        for line in source_file:
            element = json.loads(line.strip())
            if 'hours' in element:
                del element['hours']
            dest_file.write(json.dumps(element))

Simplest way is here:

1. Remove even lines and write it in some temp file 1.
2. Remove odd lines and write it in some temp file 2.
3. Combine two files in one by using paste command with -d (means delete space)

sed '0~2d' file > 1 && sed '1~2d' file > 2 && paste -d " " 1 2

' \r ' means carriage return.

The \r means nothing special as a consequence.For character-mode terminals (typically emulating even-older printing ones as above), in raw mode, \r and \n act similarly (except both in terms of the cursor, as there is no carriage or roller . Historically a \n was used to move the carriage down, while the \r was used to move the carriage back to the left side of the screen.

HTML doesn't recognize the & but it will recognize & because it is equal to & in HTML

I looked over this post someone had made: http://www.webmasterworld.com/forum21/8851.htm

Use the file-loader for that:

{
    test: /\.(svg|png|gif|jpg|ico)$/,
    include: path.resolve(__dirname, path),
    use: {
        loader: 'file-loader',
        options: {
            context: 'src/assets',
            name: 'root[path][name].[ext]'
        }
    }
}

As stated by pnt you can have multiple versions of both 32bit and 64bit Java installed at the same time on the same machine.

Taking it further from there: Here's how it might be possible to set any runtime parameters for each of those installations:

You can run javacpl.exe or javacpl.cpl of the respective Java-version itself (bin-folder). The specific control panel opens fine. Adding parameters there is possible.

You can also do as a convenience:

df[:10]

You can add script tags in your HTML document, ideally inside the which points to your javascript files. Order of the script tags are important. Load the jQuery before your script files if you want to use jQuery from your script.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="relative/path/to/your/javascript.js"></script>

Then in your javascript file you can refer to jQuery either using $ sign or jQuery. Example:

jQuery.each(arr, function(i) { console.log(i); }); 

just add container element befor your img element just to be sure that your intersted element not the first one, tested in ie,ff

In Chrome when you load a website from some HTTP server both absolute paths (e.g. /images/sth.png) and relative paths to some upper level directory (e.g. ../images/sth.png) work.

But!

When you load (in Chrome!) a HTML document from local filesystem you cannot access directories above current directory. I.e. you cannot access ../something/something.sth and changing relative path to absolute or anything else won't help.

theBoolean ^= true;

Fewer keystrokes if your variable is longer than four letters

Edit: code tends to return useful results when used as Google search terms. The code above doesn't. For those who need it, it's bitwise XOR as described here.

Try this.

function getElementsByIdStartsWith(container, selectorTag, prefix) {
    var items = [];
    var myPosts = document.getElementById(container).getElementsByTagName(selectorTag);
    for (var i = 0; i < myPosts.length; i++) {
        //omitting undefined null check for brevity
        if (myPosts[i].id.lastIndexOf(prefix, 0) === 0) {
            items.push(myPosts[i]);
        }
    }
    return items;
}

Sample HTML Markup.

<div id="posts">
    <div id="post-1">post 1</div>
    <div id="post-12">post 12</div>
    <div id="post-123">post 123</div>
    <div id="pst-123">post 123</div>
</div>

Call it like

var postedOnes = getElementsByIdStartsWith("posts", "div", "post-");

No, it's simply a typo, the "list" at the end must be capitalized. You can nest loops over the same variable just fine (although there's rarely a good reason to).

However, there are other problems with the code. For starters, you're iterating through lists, so i and j will be items not indices. Furthermore, you can't change a collection while iterating over it (well, you "can" in that it runs, but madness lies that way - for instance, you'll propably skip over items). And then there's the complexity problem, your code is O(n^2). Either convert the list into a set and back into a list (simple, but shuffles the remaining list items) or do something like this:

seen = set()
new_x = []
for x in xs:
    if x in seen:
        continue
    seen.add(x)
    new_xs.append(x)

Both solutions require the items to be hashable. If that's not possible, you'll probably have to stick with your current approach sans the mentioned problems.

In case you were struggling to change linetypes, the following answer should be helpful. (This is an addition to the solution by Andy W.)

We will try to extend the learned pattern:

cols <- c("LINE1"="#f04546","LINE2"="#3591d1","BAR"="#62c76b")
line_types <- c("LINE1"=1,"LINE2"=3)
ggplot(data=data,aes(x=a)) + 
  geom_bar(stat="identity", aes(y=h,fill = "BAR"))+ #green
  geom_line(aes(y=b,group=1, colour="LINE1", linetype="LINE1"),size=0.5) +   #red
  geom_point(aes(y=b, colour="LINE1", fill="LINE1"),size=2) +           #red
  geom_line(aes(y=c,group=1,colour="LINE2", linetype="LINE2"),size=0.5) +   #blue 
  geom_point(aes(y=c,colour="LINE2", fill="LINE2"),size=2) +           #blue
  scale_colour_manual(name="Error Bars",values=cols, 
                  guide = guide_legend(override.aes=aes(fill=NA))) + 
  scale_linetype_manual(values=line_types)+
  scale_fill_manual(name="Bar",values=cols, guide="none") +
  ylab("Symptom severity") + xlab("PHQ-9 symptoms") +
  ylim(0,1.6) +
  theme_bw() +
  theme(axis.title.x = element_text(size = 15, vjust=-.2)) +
  theme(axis.title.y = element_text(size = 15, vjust=0.3))

However, what we get is the following result:

The problem is that the linetype is not merged in the main legend. Note that we did not give any name to the method scale_linetype_manual. The trick which works here is to give it the same name as what you used for naming scale_colour_manual. More specifically, if we change the corresponding line to the following we get the desired result:

scale_linetype_manual(name="Error Bars",values=line_types)

Now, it is easy to change the size of the line with the same idea.

Note that the geom_bar has not colour property anymore. (I did not try to fix this issue.) Also, adding geom_errorbar with colour attribute spoils the result. It would be great if somebody can come up with a better solution which resolves these two issues as well.

I'd the same issue and solved it by inserting an empty input before the datepicker, that steals the focus every time the dialog is opened. This input is hidden on every opening of the dialog and shown again on closing.

Try implementing the interface as anonymous.

public class MyClass extends MySuperClass implements MyInterface{

MyInterface myInterface = new MyInterface(){

/* Overrided method from interface */
@override
public void method1(){

}

};

/* Overrided method from superclass*/
@override
public void method1(){

}

}

Python 2: isinstance(x, (int, long, float, complex)) and not isinstance(x, bool)

Python 3: isinstance(x, (int, float, complex)) and not isinstance(x, bool)

For someone who needs quick reference of C# Escape Sequences that can be used in string literals:

\t     Horizontal tab (ASCII code value: 9)

\n     Line feed (ASCII code value: 10)

\r     Carriage return (ASCII code value: 13)

\'     Single quotation mark

\"     Double quotation mark

\\     Backslash

\?     Literal question mark

\x12     ASCII character in hexadecimal notation (e.g. for 0x12)

\x1234     Unicode character in hexadecimal notation (e.g. for 0x1234)

It's worth mentioning that these (in most cases) are universal codes. So \t is 9 and \n is 10 char value on Windows and Linux. But newline sequence is not universal. On Windows it's \n\r and on Linux it's just \n. That's why it's best to use Environment.Newline which gets adjusted to current OS settings. With .Net Core it gets really important.

Workspaces can only be open in one copy of eclipse at once. Further, you took away your own write access from the looks of it. All the users in question have to have the 'admin' group for what you did to even work a little.

                        .add(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();
//                        .replace(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();

            }
        });

When we use add() in fragment

E/Keshav SecondFragment: onAttach
E/Keshav SecondFragment: onCreate
E/Keshav SecondFragment: onCreateView
E/Keshav SecondFragment: onActivityCreated
E/Keshav SecondFragment: onStart
E/Keshav SecondFragment: onResume

When we use replace() in fragment

going to first fragment to second fragment in First -->Second using replace() method

 btn_one.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getActivity(),"Click First Fragment",Toast.LENGTH_LONG).show();

                Fragment fragment = new SecondFragment();
                getActivity().getSupportFragmentManager().beginTransaction()
//                        .add(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();
                        .replace(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();

            }
        });

E/Keshav SecondFragment: onAttach
E/Keshav SecondFragment: onCreate

E/Keshav FirstFragment: onPause -------------------------- FirstFragment
E/Keshav FirstFragment: onStop --------------------------- FirstFragment
E/Keshav FirstFragment: onDestroyView -------------------- FirstFragment

E/Keshav SecondFragment: onCreateView
E/Keshav SecondFragment: onActivityCreated
E/Keshav SecondFragment: onStart
E/Keshav SecondFragment: onResume

In case of Replace First Fragment these method is extra called ( onPause,onStop,onDestroyView is extra called )

E/Keshav FirstFragment: onPause

E/Keshav FirstFragment: onStop

E/Keshav FirstFragment: onDestroyView

Static is something that any object in a class can call, that inherently belongs to an object type.

A variable can be final for an entire class, and that simply means it cannot be changed anymore. It can only be set once, and trying to set it again will result in an error being thrown. It is useful for a number of reasons, perhaps you want to declare a constant, that can't be changed.

Some example code:

class someClass
{
   public static int count=0;
   public final String mName;

   someClass(String name)
   {
     mname=name;
     count=count+1;
   }

  public static void main(String args[])
  {
    someClass obj1=new someClass("obj1");
    System.out.println("count="+count+" name="+obj1.mName);
    someClass obj2=new someClass("obj2");
    System.out.println("count="+count+" name="+obj2.mName);
  }
}

Wikipedia contains the complete list of java keywords.

It makes sure that the returned object (which is an RValue at that point) can't be modified. This makes sure the user can't do thinks like this:

myFunc() = Object(...);

That would work nicely if myFunc returned by reference, but is almost certainly a bug when returned by value (and probably won't be caught by the compiler). Of course in C++11 with its rvalues this convention doesn't make as much sense as it did earlier, since a const object can't be moved from, so this can have pretty heavy effects on performance.

There are a couple of variables to set the max number of connections. Most likely, you're running out of file numbers first. Check ulimit -n. After that, there are settings in /proc, but those default to the tens of thousands.

More importantly, it sounds like you're doing something wrong. A single TCP connection ought to be able to use all of the bandwidth between two parties; if it isn't:

• Check if your TCP window setting is large enough. Linux defaults are good for everything except really fast inet link (hundreds of mbps) or fast satellite links. What is your bandwidth*delay product?
• Check for packet loss using ping with large packets (ping -s 1472 ...)
• Check for rate limiting. On Linux, this is configured with tc
• Confirm that the bandwidth you think exists actually exists using e.g., iperf
• Confirm that your protocol is sane. Remember latency.
• If this is a gigabit+ LAN, can you use jumbo packets? Are you?

Possibly I have misunderstood. Maybe you're doing something like Bittorrent, where you need lots of connections. If so, you need to figure out how many connections you're actually using (try netstat or lsof). If that number is substantial, you might:

• Have a lot of bandwidth, e.g., 100mbps+. In this case, you may actually need to up the ulimit -n. Still, ~1000 connections (default on my system) is quite a few.
• Have network problems which are slowing down your connections (e.g., packet loss)
• Have something else slowing you down, e.g., IO bandwidth, especially if you're seeking. Have you checked iostat -x?

Also, if you are using a consumer-grade NAT router (Linksys, Netgear, DLink, etc.), beware that you may exceed its abilities with thousands of connections.

I hope this provides some help. You're really asking a networking question.

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

You can close the current window just by using the following code:

Application.Current.Windows[0].Close();

To do so without compiling the Regex first, use a lambda function - for example:

from re import match

values = ['123', '234', 'foobar']
filtered_values = list(filter(lambda v: match('^\d+$', v), values))

print(filtered_values)

Returns:

['123', '234']

filter() just takes a callable as it's first argument, and returns a list where that callable returned a 'truthy' value.

I tried most above offered solutions (the simple ones, not those offering chmod and altering internal libraries) and none of them work

Eventually what worked for me was: "Clean Project" -> "Rebuild Project" -> changed the app versionName in the build.gradle app module -> Sync Gradle -> Run the app on the device

The answer is depends how you are using the objects of javascript. As already pointed loading the javascript files at footer rather than header certainly improves the performance but care should be taken that the objects which are used are initialized later than they are loaded at footer. One more way is load the 'js' files placed in folder which will be available to all the files.

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark` 
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          AFTER `<TABLE COLUMN BEFORE THIS COLUMN>`";

I believe you need to have ADD COLUMN and use AFTER, not BEFORE.

In case you want to place column at the beginning of a table, use the FIRST statement:

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          FIRST";

GO is like the end of a script.

You could have multiple CREATE TABLE statements, separated by GO. It's a way of isolating one part of the script from another, but submitting it all in one block.

BEGIN and END are just like { and } in C/++/#, Java, etc.

They bound a logical block of code. I tend to use BEGIN and END at the start and end of a stored procedure, but it's not strictly necessary there. Where it IS necessary is for loops, and IF statements, etc, where you need more then one step...

IF EXISTS (SELECT * FROM my_table WHERE id = @id)
BEGIN
   INSERT INTO Log SELECT @id, 'deleted'
   DELETE my_table WHERE id = @id
END

n = 1 # N. . .
[x[n] for x in elements]
