The following was tested for IIS 8.5 and Windows 8.1.

As of IIS 7, Windows recommends restarting IIS via net stop/start. Via the command prompt (as Administrator):

> net stop WAS
> net start W3SVC

net stop WAS will stop W3SVC as well. Then when starting, net start W3SVC will start WAS as a dependency.

I had the same problem on Windows 7 and tried everything: cleaned DLLs, investigated modules' list, turned off "Just My Code", and so on.

The problem was solved after I've run Visual Studio "as administrator". Honestly. Why Microsoft couldn't just warn me that it's not running "as administrator"? It would save me some hours of work.

It stops and starts the services that IIS consists of.

You can think of it as closing the relevant program and starting it up again.

An instance method applies to an instance of the class (i.e. an object) whereas a class method applies to the class itself.

In C# a class method is marked static. Methods and properties not marked static are instance methods.

class Foo {
  public static void ClassMethod() { ... }
  public void InstanceMethod() { ... }
}

Identity is not equality.

• equals operator == test identity.
• equals(Object obj) method compares equality test(i.e. we need to tell equality by overriding the method)

Why do I need to override the equals and hashCode methods in Java?

First we have to understand the use of equals method.

In order to identity differences between two objects we need to override equals method.

For example:

Customer customer1=new Customer("peter");
Customer customer2=customer1;
customer1.equals(customer2); // returns true by JVM. i.e. both are refering same Object
------------------------------
Customer customer1=new Customer("peter");
Customer customer2=new Customer("peter");
customer1.equals(customer2); //return false by JVM i.e. we have two different peter customers.

------------------------------
Now I have overriden Customer class equals method as follows:
 @Override
    public boolean equals(Object obj) {
        if (this == obj)   // it checks references
            return true;
        if (obj == null) // checks null
            return false;
        if (getClass() != obj.getClass()) // both object are instances of same class or not
            return false;
        Customer other = (Customer) obj;
        if (name == null) {
            if (other.name != null)
                return false;
        } else if (!name.equals(other.name)) // it again using bulit in String object equals to identify the difference 
            return false;
        return true; 
    }
Customer customer1=new Customer("peter");
Customer customer2=new Customer("peter");
Insteady identify the Object equality by JVM, we can do it by overring equals method.
customer1.equals(customer2);  // returns true by our own logic

Now hashCode method can understand easily.

hashCode produces integer in order to store object in data structures like HashMap, HashSet.

Assume we have override equals method of Customer as above,

customer1.equals(customer2);  // returns true by our own logic

While working with data structure when we store object in buckets(bucket is a fancy name for folder). If we use built-in hash technique, for above two customers it generates two different hashcode. So we are storing the same identical object in two different places. To avoid this kind of issues we should override the hashCode method also based on the following principles.

• un-equal instances may have same hashcode.
• equal instances should return same hashcode.

From a 'SQL the language' perspective the two constructs are equivalent and which one you choose is one of those 'lifestyle' choices we all have to make. I think there is a good case for DISTINCT being more explicit (and therefore is more considerate to the person who will inherit your code etc) but that doesn't mean the GROUP BY construct is an invalid choice.

I think this 'GROUP BY is for aggregates' is the wrong emphasis. Folk should be aware that the set function (MAX, MIN, COUNT, etc) can be omitted so that they can understand the coder's intent when it is.

The ideal optimizer will recognize equivalent SQL constructs and will always pick the ideal plan accordingly. For your real life SQL engine of choice, you must test :)

PS note the position of the DISTINCT keyword in the select clause may produce different results e.g. contrast:

SELECT COUNT(DISTINCT C) FROM myTbl;

SELECT DISTINCT COUNT(C) FROM myTbl;

As of SQL Server 2012+, you can use FORMAT(value, format [, culture ])

Where the format param takes any valid standard format string or custom formatting string

Example:

SELECT FORMAT(GETDATE(), 'MM/dd/yyyy')

So it was a simple fix. Just had to move the ng-click to a scope click handler:

<input id="upload"
    type="file"
    ng-file-select="onFileSelect($files)"
    style="display: none;">

<button type="button"
    ng-click="clickUpload()">Upload</button>



$scope.clickUpload = function(){
    angular.element('#upload').trigger('click');
};

If you do not want to configure the message converters yourself, you can use either @EnableWebMvc or <mvc:annotation-driven />, add Jackson to the classpath and Spring will give you both JSON, XML (and a few other converters) by default. Additionally, you will get some other commonly used features for conversion, formatting and validation.

In response to piemesons rant against jQuery, a Vanilla JavaScript(TM) solution (tested on FF and IE):

Put this in a script tag after your markup is loaded (right before the close of the body tag) and you'll get a similar effect to the jQuery example.

a = document.getElementsByTagName('a');
for (var i = 0; i < a.length;i++) {
  a[i].getElementsByTagName('span')[1].onclick = function() { return false;};
}

This will disable the click on every 2nd span inside of an a tag. You could also check the innerHTML of each span for "description", or set an attribute or class and check that.

Here's another way you could do it:

$arr = range(1, 10);

$end = end($arr);
reset($arr);

while( list($k, $v) = each($arr) )
{
    if( $n == $end )
    {
        echo 'last!';
    }
    else
    {
        echo sprintf('%s ', $v);
    }
}

Portability between Linux and Windows is a big headache, since Linux is a POSIX-conformant system with - generally - a proper, high quality toolchain for C, whereas Windows doesn't even provide a lot of functions in the C standard library.

However, if you want to stick to the standard, you can write something like this:

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

FILE *f = fopen("textfile.txt", "rb");
fseek(f, 0, SEEK_END);
long fsize = ftell(f);
fseek(f, 0, SEEK_SET);  /* same as rewind(f); */

char *string = malloc(fsize + 1);
fread(string, 1, fsize, f);
fclose(f);

string[fsize] = 0;

Here string will contain the contents of the text file as a properly 0-terminated C string. This code is just standard C, it's not POSIX-specific (although that it doesn't guarantee it will work/compile on Windows...)

use this capitalize filter

var app = angular.module('app', []);_x000D_
_x000D_
app.controller('Ctrl', function ($scope) {_x000D_
   $scope.msg = 'hello, world.';_x000D_
});_x000D_
_x000D_
app.filter('capitalize', function() {_x000D_
    return function(input) {_x000D_
      return (angular.isString(input) && input.length > 0) ? input.charAt(0).toUpperCase() + input.substr(1).toLowerCase() : input;_x000D_
    }_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
<div ng-app="app">_x000D_
    <div ng-controller="Ctrl">_x000D_
        <p><b>My Text:</b> {{msg | capitalize}}</p>_x000D_
    </div>_x000D_
</div>

For me following worked:

in directive declare it like this:

.directive('myDirective', function() {
    return {
        restrict: 'E',
        replace: true,
        scope: {
            myFunction: '=',
        },
        templateUrl: 'myDirective.html'
    };
})  

In directive template use it in following way:

<select ng-change="myFunction(selectedAmount)">

And then when you use the directive, pass the function like this:

<data-my-directive
    data-my-function="setSelectedAmount">
</data-my-directive>

You pass the function by its declaration and it is called from directive and parameters are populated.

If your regex includes a variable, make sure to escape it.

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

This can be used like this

new RegExp(escapeRegExp(searchString), 'i')

Or in a mongoDb query like this

{ '$regex': escapeRegExp(searchString) }

Posted same comment here

I just did this for fun

    >>> s = 'a,b,c,d'
    >>> [item[::-1] for item in s[::-1].split(',', 1)][::-1]
    ['a,b,c', 'd']

Caution: Refer to the first comment in below where this answer can go wrong.

Do you have a bean declared in your context file that has an id of "articleService"? I believe that autowiring matches the id of a bean in your context files with the variable name that you are attempting to Autowire.

Just change your syntax ever so slightly:

CASE WHEN STATE = 2 AND RetailerProcessType = 1 THEN '"AUTHORISED"'
     WHEN STATE = 1 AND RetailerProcessType = 2 THEN '"PENDING"'
     WHEN STATE = 2 AND RetailerProcessType = 2 THEN '"AUTHORISED"'
     ELSE '"DECLINED"'
END

If you don't put the field expression before the CASE statement, you can put pretty much any fields and comparisons in there that you want. It's a more flexible method but has slightly more verbose syntax.

You are trying to solve the wrong problem.

Solution 1: Each time you put dirty socks in your laundry basket, tie them in a little knot. That way you will not have to do any sorting after the washing. Think of it like registering an index in a Mongo database. A little work ahead for some CPU savings in the future.

Solution 2: If it's winter, you don't have to wear matching socks. We are programmers. Nobody needs to know, as long as it works.

Solution 3: Spread the work. You want to perform such a complex CPU process asynchronously, without blocking the UI. Take that pile of socks and stuff them in a bag. Only look for a pair when you need it. That way the amount of work it takes is much less noticeable.

Hope this helps!

I believe that your problem is due to the fact that you are defining the variable v inside the test. As explained by @rmalchow, it will work you change it into

int v;
if((v = someMethod()) != 0) return true;

There is also another issue of variable scope. Even if what you tried were to work, what would be the point? Assuming you could define the variable scope inside the test, your variable v would not exist outside that scope. Hence, creating the variable and assigning the value would be pointless, for you would not be able to use it.

Variables exist only in the scope they were created. Since you are assigning the value to use it afterwards, consider the scope where you are creating the varible so that it may be used where needed.

Or whatever you need.

You may try to:

• backup your database folder from C:\xampp\mysql\data (.frm & .ibd files only corresponding your table names)
• reinstall xampp and recopy DB folder at C:\xampp\mysql\data

• modify my.ini add

  [mysqld]
  innodb_file_per_table = on
  

• then open phpmyadmin (or any other DB viewer as Navicat or MYSQL Workbench) and run

  ALTER TABLE tbl_name IMPORT TABLESPACE 
  

  for each table

• Once you can open your tables make a full mysql dump

• delete everything and make a clean install

I know, a lot of work to do that you don't need it.

Root cause: Corrupted user profile of user account used to start database

The main thread here seems to be a corrupted user account profile for the account that is used to start the DB engine. This is the account that was specified for the "SQL Server Database" engine during installation. In the setup event log, it's also indicated by the following entry:

SQLSVCACCOUNT:                 NT AUTHORITY\SYSTEM

According to the link provided by @royki:

The root cause of this issue, in most cases, is that the profile of the user being used for the service account (in my case it was local system) is corrupted.

This would explain why other respondents had success after changing to different accounts:

• bmjjr suggests changing to "NT AUTHORITY\NETWORK SERVICE"
• comments to @bmjjr indicate different accounts "I used NT AUTHORITY\LOCAL SERVICE. That helped too"
• @Julio Nobre had success with "NT Authority\System "

Fix: reset the corrupt user profile

To fix the user profile that's causing the error, follow the steps listed KB947215.

The main steps from KB947215 are summarized as follows:-

1. Open regedit
2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList

3. Navigate to the SID for the corrupted profile

   To find the SID, click on each SID GUID, review the value for the ProfileImagePath value, and see if it's the correct account. For system accounts, there's a different way to know the SID for the account that failed:

The main system account SIDs of interest are:

SID          Name               Also Known As
S-1-5-18     Local System       NT AUTHORITY\SYSTEM
S-1-5-19     LocalService       NT AUTHORITY\LOCAL SERVICE
S-1-5-20     NetworkService     NT AUTHORITY\NETWORK SERVICE

For information on additional SIDs, see Well-known security identifiers in Windows operating systems.

4. If there are two entries (e.g. with a .bak) at the end for the SID in question, or the SID in question ends in .bak, ensure to follow carefully the steps in the KB947215 article.
5. Reset the values for RefCount and State to be 0.
6. Reboot.
7. Retry the SQL Server installation.

Create your own unistd.h header and include the needed headers for function prototypes.

Getting collation error #1273 - Unknown collation: 'utf8mb4_unicode_520_ci' is caused by the difference of the MySQL version from which you export and our MySQL server to which you import. Basically, the Wordpress library for newer version checks to see what version of SQL your site is running on. If it uses MySQL version 5.6 or more, it assumes the use of a new and improved Unicode Collation Algorithm (UCA) called “utf8mb4_unicode_520_ci”. This is great unless you end up moving your WordPress site from a newer 5.6 version of MySQL to an older, pre 5.6 version of MySQL.

To resolve this you will either have to edit your SQL export file and do a search and replace, changing all instances of ‘utf8mb4_unicode_520_ci’ to ‘utf8mb4_unicode_ci’. Or follow the steps below if you have a PHPMyAdmin:

1. Click the Export tab for the database
2. Click the Custom radio button.
3. Go the section titled Format-specific options and change the drop-down for Database system or older MySQL server to maximize output compatibility with: from NONE to MYSQL40.
4. Scroll to the bottom and click GO.

There is the solution if you need only outline without border. It's not mine. I got if from Bootstrap css file. If you specify outline: 1px auto certain_color, you'll get thin outer line around div of certain color. In this case the specified width has no matter, even if you specify 10 px width, anyway it will be thin line. The key word in mentioned rule is "auto".
If you need outline with rounded corners and certain width, you may add css rule on border with needed width and same color. It makes outline thicker.

I had the same frustrating issue, and I didn't want to create an EditorTemplate that applied to all DateTime values (there were times in my UI where I wanted to display the time and not a jQuery UI drop-down calendar). In my research, the root issues I came across were:

• The standard TextBoxFor helper allowed me to apply a custom class of "date-picker" to render the unobtrusive jQuery UI calender, but TextBoxFor wouldn't format a DateTime without the time, therefore causing the calendar rendering to fail.
• The standard EditorFor would display the DateTime as a formatted string (when decorated with the proper attributes such as [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")], but it wouldn't allow me to apply the custom "date-picker" class.

Therefore, I created custom HtmlHelper class that has the following benefits:

• The method automatically converts the DateTime into the ShortDateString needed by the jQuery calendar (jQuery will fail if the time is present).
• By default, the helper will apply the required htmlAttributes to display a jQuery calendar, but they can be overridden if needs be.
• If the date is null, ASP.NET MVC will put a date of 1/1/0001 as a value.

This method replaces that with an empty string.

public static MvcHtmlString CalenderTextBoxFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, object htmlAttributes = null)
{
    var mvcHtmlString = System.Web.Mvc.Html.InputExtensions.TextBoxFor(htmlHelper, expression, htmlAttributes ?? new { @class = "text-box single-line date-picker" });
    var xDoc = XDocument.Parse(mvcHtmlString.ToHtmlString());
    var xElement = xDoc.Element("input");
    if (xElement != null)
    {
        var valueAttribute = xElement.Attribute("value");
        if (valueAttribute != null)
        {
            valueAttribute.Value = DateTime.Parse(valueAttribute.Value).ToShortDateString();
            if (valueAttribute.Value == "1/1/0001")
                valueAttribute.Value = string.Empty;
        }
    }
    return new MvcHtmlString(xDoc.ToString());
}

And for those that want to know the JQuery syntax that looks for objects with the date-picker class decoration to then render the calendar, here it is:

$(document).ready(function () {
    $('.date-picker').datepicker({ inline: true, maxDate: 0, changeMonth: true, changeYear: true });
    $('.date-picker').datepicker('option', 'showAnim', 'slideDown');
});

For an app created with create-react-app I managed to see the version:

1. Open Chrome Dev Tools / Firefox Dev Tools,
2. Search and open main.XXXXXXXX.js file where XXXXXXXX is a builds hash /could be different,
3. Optional: format source by clicking on the {} to show the formatted source,
4. Search as text inside the source for react-dom,
5. in Chrome was found: "react-dom": "^16.4.0",
6. in Firefox was found: 'react-dom': '^16.4.0'

The app was deployed without source map.

To add slightly to the other answers, if you actually want to catch SIGTERM (the default signal sent by the kill command), you can use syscall.SIGTERM in place of os.Interrupt. Beware that the syscall interface is system-specific and might not work everywhere (e.g. on windows). But it works nicely to catch both:

c := make(chan os.Signal, 2)
signal.Notify(c, os.Interrupt, syscall.SIGTERM)
....

If you really want to split every word (bash meaning) into a different array index completely changing the array in every while loop iteration, @ruakh's answer is the correct approach. But you can use the read property to split every read word into different variables column1, column2, column3 like in this code snippet

while IFS=$'\t' read -r column1 column2 column3 ; do
  printf "%b\n" "column1<${column1}>"
  printf "%b\n" "column2<${column2}>"
  printf "%b\n" "column3<${column3}>"
done < "myfile"

to reach a similar result avoiding array index access and improving your code readability by using meaningful variable names (of course using columnN is not a good idea to do so).

Read file contents into a variable:

for /f "delims=" %%x in (version.txt) do set Build=%%x

or

set /p Build=<version.txt

Both will act the same with only a single line in the file, for more lines the for variant will put the last line into the variable, while set /p will use the first.

Using the variable – just like any other environment variable – it is one, after all:

%Build%

So to check for existence:

if exist \\fileserver\myapp\releasedocs\%Build%.doc ...

Although it may well be that no UNC paths are allowed there. Can't test this right now but keep this in mind.

Try this

SELECT CONCAT('"',GROUP_CONCAT(id),'"') FROM table_level 
where parent_id=4 group by parent_id;

Result will be

hi,that maybe the project's problem,

chose the project and setting you eclipse:

res/layout/layout-w720dp

Chek the Device Width and Height using Display Metrics

Place/figure out which layout suits for the resulted width of the Device .

let smallestScreenWidthDp="assume some value(Which will be derived from Display metrics)"

All should be checked before setContentView().Otherwise you put yourself in trouble

     Configuration config = getResources().getConfiguration();


        if (config.smallestScreenWidthDp >= 600) {
            setContentView(R.layout.layout-w600dp);
        } else {
            setContentView(R.layout.main_activity);

A Simple but more effective way:
new FormData() is itself like a container (or a bag). You can put everything attr or file in itself. The only thing you'll need to append the attribute, file, fileName eg:

let formData = new FormData()
formData.append('input', input.files[0], input.files[0].name)

and just pass it in AJAX request. Eg:

    let formData = new FormData()
    var d = $('#fileid')[0].files[0]

    formData.append('fileid', d);
    formData.append('inputname', value);

    $.ajax({
        url: '/yourroute',
        method: 'POST',
        contentType: false,
        processData: false,
        data: formData,
        success: function(res){
            console.log('successfully')
        },
        error: function(){
            console.log('error')
        }
    })

You can append n number of files or data with FormData.

and if you're making AJAX Request from Script.js file to Route file in Node.js beware of using
req.body to access data (ie text)
req.files to access file (ie image, video etc)

I suggest you to take a look into SharpGrabber - a .NET Standard library I've written just for this purpose. It is newer than YouTubeExtractor and libvideo. It supports YouTube and Instagram as the time of this answer. This project also offers high-quality video and audio muxing and a cross-platform desktop application.

Your mistake is using new DateTime(), which returns January 1, 0001 at 00:00:00.000 instead of current date and time. The correct syntax to get current date and time is DateTime.Now, so change this:

String timeStamp = GetTimestamp(new DateTime());

to this:

String timeStamp = GetTimestamp(DateTime.Now);

In CodeIgniter 3.0-dev (get it from github) this is not working because the CI is search as first letter uppercase.

You can find the code on system/core/Loader.php line 282 or bellow:

$model = ucfirst(strtolower($model));

foreach ($this->_ci_model_paths as $mod_path)
{
    if ( ! file_exists($mod_path.'models/'.$path.$model.'.php'))
    {
        continue;
    }

    require_once($mod_path.'models/'.$path.$model.'.php');

    $CI->$name = new $model();
    $this->_ci_models[] = $name;
    return $this;
}

This mean that we need to create the file with the following name on application/models/Logon_mode.php

public interface BookService {
    String getAuthor();
    void queryBookTitle(BookServiceCallback callback);
}

You can stub getAuthor() using doAnswer and thenReturn.

BookService service = mock(BookService.class);
when(service.getAuthor()).thenReturn("Joshua");
// or..
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        return "Joshua";
    }
}).when(service).getAuthor();

Note that when using doAnswer, you can't pass a method on when.

// Will throw UnfinishedStubbingException
doAnswer(invocation -> "Joshua").when(service.getAuthor());

So, when would you use doAnswer instead of thenReturn? I can think of two use cases:

1. When you want to "stub" void method.

Using doAnswer you can do some additionals actions upon method invocation. For example, trigger a callback on queryBookTitle.

BookServiceCallback callback = new BookServiceCallback() {
    @Override
    public void onSuccess(String bookTitle) {
        assertEquals("Effective Java", bookTitle);
    }
};
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        BookServiceCallback callback = (BookServiceCallback) invocation.getArguments()[0];
        callback.onSuccess("Effective Java");
        // return null because queryBookTitle is void
        return null;
    }
}).when(service).queryBookTitle(callback);
service.queryBookTitle(callback);

2. When you are using Spy instead of Mock

When using when-thenReturn on Spy Mockito will call real method and then stub your answer. This can cause a problem if you don't want to call real method, like in this sample:

List list = new LinkedList();
List spy = spy(list);
// Will throw java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
when(spy.get(0)).thenReturn("java");
assertEquals("java", spy.get(0));

Using doAnswer we can stub it safely.

List list = new LinkedList();
List spy = spy(list);
doAnswer(invocation -> "java").when(spy).get(0);
assertEquals("java", spy.get(0));

Actually, if you don't want to do additional actions upon method invocation, you can just use doReturn.

List list = new LinkedList();
List spy = spy(list);
doReturn("java").when(spy).get(0);
assertEquals("java", spy.get(0));

If you came here from google because tab isnt indenting, this can also be because "Tab Moves Focus" is on. It is at the bottom right, and if you have a large enough monitor you may miss it despite it being highlighted.

Click the Green area or Ctrl + M to make it stop. I'm not sure it can be disabled entirely, then again I dont know why a code editor would want to mess with something like indenting.

please set dataType config property in your ajax call and give it another try!

another point is you are using ajax call setup configuration properties as string and it is wrong as reference site

$.ajax({

    url : 'http://voicebunny.comeze.com/index.php',
    type : 'GET',
    data : {
        'numberOfWords' : 10
    },
    dataType:'json',
    success : function(data) {              
        alert('Data: '+data);
    },
    error : function(request,error)
    {
        alert("Request: "+JSON.stringify(request));
    }
});

I hope be helpful!

Follow following step to work genemotion like charm.

1. Open Oracle VM virtual Box

2. File -> Preferences ( ctrl + g ) -> open one dialog box -> select Network -> select Host only network choose you adapter ( there are three button on right side -add -remove -Edit host only nw.,

   If you dont have any adapter then create.

3. After selecting your adapater choose Edit Edit host only network(space)

4. Open one dialog box then choose DHCP server choose Enable Server and fill all ip addresses.

   like

   IPv4 address/netmask: 192.168.56.1/255.255.255.0 (on Adapter tab)

   DHCP server enabled checked (on DHCP server tab)

   Server address/netmask: 192.168.56.100/255.255.255.0

   Server lower/upper address: 192.168.56.100/192.168.56.254

5. Give ok.

6. In starting of the oracle virtual machine there are different tab like General ,system , Display ,storage,Network etc.. Click on Network

7. Open one dialog box, select Enable Network adapter attached to ->host only network and main thing is that in Name tab, choose adapter that you are choosing in preference both adapter much be match example you choose virtualbox...2 then here also choose that one.

8. Ok.

9. Now play your genemotion. if again error come then again restart to play you succedd.

10. :)

See full video here to see above all step and work well with genemotion.

When I was in college, I did a little bit of work in a language called SNOBOL. The entire language, while cool, is one big WTF.

It has the weirdest syntax I've ever seen. Instead of GoTo, you use :(label). And who needs if's when you have :S(label) (goto label on success/true) and :F(label) (goto label on failure/false) and you use those functions on the line checking some condition or reading a file. So the statement:

H = INPUT :F(end)

will read the next line from a file or the console and will go to the label "end" if the read fails (because EOF is reached or any other reason).

Then there is the $ sign operator. That will use the value in a variable as a variable name. So:

ANIMAL = 'DOG'
DOG = 'BARK'
output = $ANIMAL

will put the value 'BARK' on teh console. And because that isn't weird enough:

$DOG = 'SOUND'

will create variable named BARK (see the value assigned to DOG above) and give it a value of 'SOUND'.

The more you look at it, the worse it gets. The best statement I ever found about SNOBOL (from link text) is "the power of the language and its rather idiomatic control flow features make SNOBOL4 code almost impossible to read and understand after writing it. "

If you're using LESS/SASS CSS transformation there's an option useNativeMinification which can be set to false to disable minification (in web.config). For my purposes I just change it here when I need to, but you could use web.config transformations to always enable it on release build or perhaps find a way modify it in code.

<less useNativeMinification="false" ieCompat="true" strictMath="false"
      strictUnits="false" dumpLineNumbers="None">

Tip: The whole point of this is to view your CSS, which you can do in the browser inspect tools or by just opening the file. When bundling is enabled that filename changes on every compile so I put the following at the top of my page so I can view my compiled CSS eaily in a new browser window every time it changes.

@if (Debugger.IsAttached) 
{
    <a href="@Styles.Url(ViewBag.CSS)" target="css">View CSS</a>
}

this will be a dynamic URL something like https://example.com/Content/css/bundlename?v=UGd0FjvFJz3ETxlNN9NVqNOeYMRrOkQAkYtB04KisCQ1

Update: I created a web.config transformation to set it to true for me during deployment / release build

  <bundleTransformer xmlns="http://tempuri.org/BundleTransformer.Configuration.xsd">
    <less xdt:Transform="Replace" useNativeMinification="true" ieCompat="true" strictMath="false" strictUnits="false" dumpLineNumbers="None">
      <jsEngine name="MsieJsEngine" />
    </less>
  </bundleTransformer>

Just updating this question with a more modern wrapper This library wraps Pillow (a fork of PIL) https://pypi.org/project/python-resize-image/

Allowing you to do something like this :-

from PIL import Image
from resizeimage import resizeimage

fd_img = open('test-image.jpeg', 'r')
img = Image.open(fd_img)
img = resizeimage.resize_width(img, 200)
img.save('test-image-width.jpeg', img.format)
fd_img.close()

A list comprehension is absolutely the way to do this. Another way that should be faster is map and itemgetter.

import operator

new_list = map(operator.itemgetter(1), old_list)

In response to the comment that the OP couldn't find an answer on google, I'll point out a super naive way to do it.

new_list = []
for item in old_list:
    new_list.append(item[1])

This uses:

1. Declaring a variable to reference an empty list.
2. A for loop.
3. Calling the append method on a list.

If somebody is trying to learn a language and can't put together these basic pieces for themselves, then they need to view it as an exercise and do it themselves even if it takes twenty hours.

One needs to learn how to think about what one wants and compare that to the available tools. Every element in my second answer should be covered in a basic tutorial. You cannot learn to program without reading one.

Try taking a look at the following libraries too:

xlwings - for getting data into and out of a spreadsheet from Python, as well as manipulating workbooks and charts

ExcelPython - an Excel add-in for writing user-defined functions (UDFs) and macros in Python instead of VBA

I would like to add a data.table variant using the rank() function which provides the additional possibility to change the ordering and thus makes it a bit more flexible than the seq_len() solution and is pretty similar to row_number functions in RDBMS.

# Variant with ascending ordering
library(data.table)
dt <- data.table(df)
dt[, .( val
   , num = rank(val))
    , by = list(cat)][order(cat, num),]

    cat        val num
 1: aaa 0.05638315   1
 2: aaa 0.25767250   2
 3: aaa 0.30776611   3
 4: aaa 0.46854928   4
 5: aaa 0.55232243   5
 6: bbb 0.17026205   1
 7: bbb 0.37032054   2
 8: bbb 0.48377074   3
 9: bbb 0.54655860   4
10: bbb 0.81240262   5
11: ccc 0.28035384   1
12: ccc 0.39848790   2
13: ccc 0.62499648   3
14: ccc 0.76255108   4

# Variant with descending ordering
dt[, .( val
   , num = rank(-val))
    , by = list(cat)][order(cat, num),]

You need to make sure the IIS Management Console is installed.

This should make life much easier. You can simply use Response.RedirectWithData(...) method in your web application easily.

                                ByVal aData As NameValueCollection)
        aThis.Clear()
        Dim sb As StringBuilder = New StringBuilder()

        sb.Append("<html>")
        sb.AppendFormat("<body onload='document.forms[""form""].submit()'>")
        sb.AppendFormat("<form name='form' action='{0}' method='post'>", aDestination)

        For Each key As String In aData
            sb.AppendFormat("<input type='hidden' name='{0}' value='{1}' />", key, aData(key))
        Next

        sb.Append("</form>")
        sb.Append("</body>")
        sb.Append("</html>")

        aThis.Write(sb.ToString())

The documentation states several ways to do this.

If you want to replace the default ObjectMapper completely, define a @Bean of that type and mark it as @Primary.

Defining a @Bean of type Jackson2ObjectMapperBuilder will allow you to customize both default ObjectMapper and XmlMapper (used in MappingJackson2HttpMessageConverter and MappingJackson2XmlHttpMessageConverter respectively).

I guess you are using Rails 4. If so, the needed parameters must be marked as required.

You might want to do it like this:

class UsersController < ApplicationController

  def create
    @user = User.new(user_params)
    # ...
  end

  private

  def user_params
    params.require(:user).permit(:username, :email, :password, :salt, :encrypted_password)
  end
end

Use Javascript's setTimeout:

<body onload="setTimeout(function(){window.location = 'form2.html';}, 5000)">

def attributeSelection():
balance = 25
print("Your SP balance is currently 25.")
strength = input("How much SP do you want to put into strength?")
balanceAfterStrength = balance - int(strength)
if balanceAfterStrength == 0:
    print("Your SP balance is now 0.")
    attributeConfirmation()
elif strength < 0:
    print("That is an invalid input. Restarting attribute selection. Keep an eye on your balance this time!")
    attributeSelection()
elif strength > balance:
    print("That is an invalid input. Restarting attribute selection. Keep an eye on your balance this time!")
    attributeSelection()
elif balanceAfterStrength > 0 and balanceAfterStrength < 26:
    print("Ok. You're balance is now at " + str(balanceAfterStrength) + " skill points.")
else:
    print("That is an invalid input. Restarting attribute selection.")
    attributeSelection()

This issue is becoming very now, specially for users installing visual studio on windows 10 platform. What Microsoft suggests is disable your anti virus and anti malware programs and always run setup with admin permission.

But in my case I have to do lot more things to get rid of this issue: 1. Disabled AVG realtime protaction 2. Disabled AVG from task manager 3. Remove all the files and folders from system temp folder. (You can open it by typing %temp% and hit enter in run prompt) 4. Run setup again as admin

Here is a complete list of incidents that I faced in this issue (visual studio 2015 installation got stuck)

And how I resolved it

And if you would like to use an existing context, rather than a new context which would be loaded from xml configuration by org.springframework.web.context.ContextLoaderListener, then see -> https://stackoverflow.com/a/40694787/3004747

If you have cloned your repo using url that contains your username, then you should also change remote.origin.url property because otherwise it keeps asking password for the old username.

example:

remote.origin.url=https://<old_uname>@<repo_url>

should change to

remote.origin.url=https://<new_uname>@<repo_url>

A slightly simpler syntax (in Robomongo at least) worked for me:

db.database.save({ Year : NumberInt(2015) });

This can also happen when using an old version of Java that isn't capable of communicating properly with the HTTPS protocol that is now required. Version 8 and above should work as of the time writing this.

c.Request["AP"] will read posted values. Also you need to use a submit button to post the form:

<input type="submit" value="Submit" />

instead of

<input type=button value="Submit" />

Solution might be this simple:

    sudo su 
    
    nano /etc/zabbix/zabbix-server.conf

Remove "#" in front of DBPassword=YourPassword (will change from blue to grey)

Ctrl x (Y to save and press enter to exit)

    service zabbix-server restart

Now you can refresh your browser running ZABBIX. If not, you will have to do the same steps for CacheSize=32M

You do not have to change anything in /etc/zabbix/web/zabbix.conf.php (localhost is fine)

When editing anything, remember "#" in front of line means invisible to linux.

Try using the ACQUIRE_CAUSES_WAKEUP flag when you create the wake lock. The ON_AFTER_RELEASE flag just resets the activity timer to keep the screen on a bit longer.

Many answers are already there, I just need to identify one difference which is not there.

for loop is fail-safe while foreach loop is fail-fast.

Fail-fast iteration throws ConcurrentModificationException if iteration and modification are done at the same time in object.

However, fail-safe iteration keeps the operation safe from failing even if the iteration goes in infinite loop.

public class ConcurrentModification {
    public static void main(String[] args) {
        List<String> str = new ArrayList<>();

        for(int i=0; i<1000; i++){
            str.add(String.valueOf(i));
        }

        /**
         * this for loop is fail-safe. It goes into infinite loop but does not fail. 
         */
        for(int i=0; i<str.size(); i++){
            System.out.println(str.get(i));
            str.add(i+ "  " + "10");
        }

        /**
         * throws ConcurrentModificationexception 
        for(String st: str){
            System.out.println(st);
            str.add("10");
        }
        */

        /* throws ConcurrentModificationException 
         Iterator<String> itr = str.iterator();
        while(itr.hasNext()) {
            System.out.println(itr.next());
            str.add("10");
        }*/
    }
} 

Hope this helps to understand the difference between for and foreach loop through different angle.

I found a good blog to go through the differences between fail-safe and fail-fast, if anyone interested:

Why strtok() is a bad idea

Do not use strtok() in normal code, strtok() uses static variables which have some problems. There are some use cases on embedded microcontrollers where static variables make sense but avoid them in most other cases. strtok() behaves unexpected when more than 1 thread uses it, when it is used in a interrupt or when there are some other circumstances where more than one input is processed between successive calls to strtok(). Consider this example:

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

//Splits the input by the / character and prints the content in between
//the / character. The input string will be changed
void printContent(char *input)
{
    char *p = strtok(input, "/");
    while(p)
    {
        printf("%s, ",p);
        p = strtok(NULL, "/");
    }
}

int main(void)
{
    char buffer[] = "abc/def/ghi:ABC/DEF/GHI";
    char *p = strtok(buffer, ":");
    while(p)
    {
        printContent(p);
        puts(""); //print newline
        p = strtok(NULL, ":");
    }
    return 0;
}

You may expect the output:

abc, def, ghi,
ABC, DEF, GHI,

But you will get

abc, def, ghi,

This is because you call strtok() in printContent() resting the internal state of strtok() generated in main(). After returning, the content of strtok() is empty and the next call to strtok() returns NULL.

What you should do instead

You could use strtok_r() when you use a POSIX system, this versions does not need static variables. If your library does not provide strtok_r() you can write your own version of it. This should not be hard and Stackoverflow is not a coding service, you can write it on your own.

The underscore is simply a convention; nothing more. As such, its use is always somewhat different to each person. Here's how I understand them for the two languages in question:

In C++, an underscore usually indicates a private member variable.

In C#, I usually see it used only when defining the underlying private member variable for a public property. Other private member variables would not have an underscore. This usage has largely gone to the wayside with the advent of automatic properties though.

Before:

private string _name;
public string Name
{
    get { return this._name; }
    set { this._name = value; }
}

After:

public string Name { get; set; }

You can create an appropriate table through management studio interface and insert data into the table like it's shown below. It may take some time depending on the amount of data, but it is very handy.

I don't see anything like this posted around here and just got here from a closed question on the same subject, but why not just do something like this(if you know the type of the list you want to split):

>>> a = [1, 2, 3, 5, 10, [1, 25, 11, [1, 0]]]    
>>> g = str(a).replace('[', '').replace(']', '')    
>>> b = [int(x) for x in g.split(',') if x.strip()]

You would need to know the type of the elements but I think this can be generalised and in terms of speed I think it would be faster.

If you can't change the type of your input array the following will work:

final int[] data = new int[] { 5, 4, 2, 1, 3 };
final Integer[] sorted = ArrayUtils.toObject(data);
Arrays.sort(sorted, new Comparator<Integer>() {
    public int compare(Integer o1, Integer o2) {
        // Intentional: Reverse order for this demo
        return o2.compareTo(o1);
    }
});
System.arraycopy(ArrayUtils.toPrimitive(sorted), 0, data, 0, sorted.length);

This uses ArrayUtils from the commons-lang project to easily convert between int[] and Integer[], creates a copy of the array, does the sort, and then copies the sorted data over the original.

As other people have pointed out, it is most likely related to another process using port 9999. On Windows, run the command:

netstat -a -n | grep "LIST"

And it should list anything there that's hogging the port. Of course you'll then have to go and manually kill those programs in Task Manager. If this still doesn't work, replace the line:

serverSocket = new ServerSocket(9999);

With:

InetAddress locIP = InetAddress.getByName("192.168.1.20");
serverSocket = new ServerSocket(9999, 0, locIP);

Of course replace 192.168.1.20 with your actual IP address, or use 127.0.0.1.

You can use nested ternary if statements.

# if-else ternary construct
country_code = 'USA'
is_USA = True if country_code == 'USA' else False
print('is_USA:', is_USA)

# if-elif-else ternary construct
# Create function to avoid repeating code.
def get_age_category_name(age):
    age_category_name = 'Young' if age <= 40 else ('Middle Aged' if age > 40 and age <= 65 else 'Senior')
    return age_category_name

print(get_age_category_name(25))
print(get_age_category_name(50))
print(get_age_category_name(75))

Calling Store Procedure in C#

    SqlCommand cmd = new SqlCommand("StoreProcedureName",con);
    cmd.CommandType=CommandType.StoredProcedure;
    cmd.Parameters.AddWithValue("@value",txtValue.Text);
    con.Open();
    int rowAffected=cmd.ExecuteNonQuery();
    con.Close();

It solved for me using

checkout scm: ([
                    $class: 'GitSCM',
                    userRemoteConfigs: [[credentialsId: '******',url: ${project_url}]],
                    branches: [[name: 'refs/tags/${project_tag}']]
            ])

I was able to get SSL working with the following boilerplate code:

var fs = require('fs'),
    http = require('http'),
    https = require('https'),
    express = require('express');

var port = 8000;

var options = {
    key: fs.readFileSync('./ssl/privatekey.pem'),
    cert: fs.readFileSync('./ssl/certificate.pem'),
};

var app = express();

var server = https.createServer(options, app).listen(port, function(){
  console.log("Express server listening on port " + port);
});

app.get('/', function (req, res) {
    res.writeHead(200);
    res.end("hello world\n");
});

I assume you called a function with an argument which was defined without taking any.

def f()
  puts "hello world"
end

f(1)   # <= wrong number of arguments (1 for 0)

Make sure to use the latest npm version while installing packages using npm.

While installing JavaScript, mention the latest version of NodeJS. For example, while installing JavaScript using devtools, use the below code:

devtools i --javascript nodejs:10.15.1

This will download and install the mentioned NodeJS version. Try installing the packages with npm after updating the version. This worked for me.

There's now also Leaflet, which is built with mobile devices in mind.

There is a Quick Start Guide for leaflet. Besides basic features such as markers, with plugins it also supports routing using an external service.

For a simple map, it is IMHO easier and faster to set up than OpenLayers, yet fully configurable and tweakable for more complex uses.

TL;DR. In Visual Studio 2019, when you add an Icon resource to a Win32 (desktop) application you get an auto-generated icon file that has the formats below. I assume that the #1 developer tool for Windows does this right. Thus, a Windows compatible should have the following formats:

| Resolution | Color depth | Format |
|:-----------|------------:|:------:|
| 256x256    |      32-bit |  PNG   |
| 64x64      |      32-bit |  BMP   |
| 48x48      |      32-bit |  BMP   |
| 32x32      |      32-bit |  BMP   |
| 16x16      |      32-bit |  BMP   |

If you don't support legacy browsers, I'd use flexbox because it's well supported and will simply solve most of your layout problems.

#table-id td:nth-child(1) { 
    /* nth-child(1) is the first column, change to fit your needs */
    display: flex;
    justify-content: center;
}

This centers all content in the first <td> of every row.

First off, are you setting your desired JRE or your desired JDK?

Even if your Eclipse is set up properly, there might be a wacky project-specific setting somewhere. You can open up a context menu on a given Java project in the Project Explorer and select Properties > Java Compiler to check on that.

If none of that helps, leave a comment and I'll take another look.

There is the concatenate function. For example

=CONCATENATE(E2,"-",F2)

Here's the Query Analyzer template for an in-line function - it returns 2 values by default:

-- =============================================  
-- Create inline function (IF)  
-- =============================================  
IF EXISTS (SELECT *   
   FROM   sysobjects   
   WHERE  name = N'<inline_function_name, sysname, test_function>')  
DROP FUNCTION <inline_function_name, sysname, test_function>  
GO  

CREATE FUNCTION <inline_function_name, sysname, test_function>   
(<@param1, sysname, @p1> <data_type_for_param1, , int>,   
 <@param2, sysname, @p2> <data_type_for_param2, , char>)  
RETURNS TABLE   
AS  
RETURN SELECT   @p1 AS c1,   
        @p2 AS c2  
GO  

-- =============================================  
-- Example to execute function  
-- =============================================  
SELECT *   
FROM <owner, , dbo>.<inline_function_name, sysname, test_function>   
    (<value_for_@param1, , 1>,   
     <value_for_@param2, , 'a'>)  
GO  

Simply use is_empty() or make function like:-

def is_empty(any_structure):
    if any_structure:
        print('Structure is not empty.')
        return True
    else:
        print('Structure is empty.')
        return False  

It can be used for any data_structure like a list,tuples, dictionary and many more. By these, you can call it many times using just is_empty(any_structure).

You could give it a try. The problem is that Windows inserts a carriage return as well as a line feed when given a new line. Unix-systems just insert a line feed. So the extra carriage return character could be the reason why your eclipse messes up with the newlines.

Grab one or two files from your project and convert them. You could use Notepad++ to do so. Just open the file, go to Format->Convert to Unix (when you are using windows).

In Linux just try this on a command line:

sed 's/$'"/`echo \\\r`/" yourfile.java > output.java

I found a much easier way, it doesn't even use SP.UserProfiles.js. I don't know if it applies to each one's particular case, but definitely worth sharing.

//assume we have a client context called context.
var web = context.get_web();
var user = web.get_currentUser(); //must load this to access info.
context.load(user);
context.executeQueryAsync(function(){
    alert("User is: " + user.get_title()); //there is also id, email, so this is pretty useful.
}, function(){alert(":(");});

Anyways, thanks to your answers, I got to mingle a bit with UserProfiles, even though it is not really necessary for my case.

To further expand on @neontapir's solution, here's a more generic solution that can apply to HttpRequestMessage or HttpResponseMessage equally and doesn't require hand coded expressions or functions.

using System.Net.Http;
using System.Collections.Generic;
using System.Linq;

public static class HttpResponseMessageExtensions
{
    public static T GetFirstHeaderValueOrDefault<T>(
        this HttpResponseMessage response,
        string headerKey)
    {
        var toReturn = default(T);

        IEnumerable<string> headerValues;

        if (response.Content.Headers.TryGetValues(headerKey, out headerValues))
        {
            var valueString = headerValues.FirstOrDefault();
            if (valueString != null)
            {
                return (T)Convert.ChangeType(valueString, typeof(T));
            }
        }

        return toReturn;
    }
}

Sample usage:

var myValue = response.GetFirstHeaderValueOrDefault<int>("MyValue");

take a global variable for current selection of spinner:

int currentItem = 0;

spinner_counter = (Spinner)findViewById(R.id.spinner_counter);
String[] value={"20","40","60","80","100","All"};
aa=new ArrayAdapter<String>(this,R.layout.spinner_item_profile,value);
aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner_counter.setAdapter(aa);

spinner_counter.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            if(currentItem == position){
                return; //do nothing
            }
            else
            {
                 TextView spinner_item_text = (TextView) view;
                 //write your code here
            }
            currentItem = position;
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });

//R.layout.spinner_item_profile

You can specify the style of the plotted line when calling df.plot:

df.plot(x='col_name_1', y='col_name_2', style='o')

The style argument can also be a dict or list, e.g.:

import numpy as np
import pandas as pd

d = {'one' : np.random.rand(10),
     'two' : np.random.rand(10)}

df = pd.DataFrame(d)

df.plot(style=['o','rx'])

All the accepted style formats are listed in the documentation of matplotlib.pyplot.plot.

If you want to feed more than one id to your query and get next_id for all of them...

Assign cur_id in your select field and then feed it to subquery getting next_id inside select field. And then select just next_id.

Using longneck answer to calc next_id:

select next_id
from (
    select id as cur_id, (select min(id) from `foo` where id>cur_id) as next_id 
    from `foo` 
) as tmp
where next_id is not null;

The Oracle error ORA-01036 means that the query uses an undefined variable somewhere. From the query we can determine which variables are in use, namely all that start with @. However, if you're inputting this into an advanced query, it's important to confirm that all variables have a matching input parameter, including the same case as in the variable name, if your Oracle database is Case Sensitive.

this worked fine for me.

$('#customText').on('keyup', function(event) {
   var len = $(this).val().length;
   if (len >= 40) {
      $(this).val($(this).val().substring(0, len-1));
   }
});

I found "kill -0" does not work if the process is owned by root (or other), so I used pgrep and came up with:

while pgrep -u root process_name > /dev/null; do sleep 1; done

This would have the disadvantage of probably matching zombie processes.

In Rails 2, I would have written:

validates_uniqueness_of :zipcode, :scope => :recorded_at

In Rails 3:

validates :zipcode, :uniqueness => {:scope => :recorded_at}

For multiple attributes:

validates :zipcode, :uniqueness => {:scope => [:recorded_at, :something_else]}

pydoc is fantastic for generating documentation, but the documentation has to be written in the first place. You must have docstrings in your source code as was mentioned by RocketDonkey in the comments:

"""
This example module shows various types of documentation available for use
with pydoc.  To generate HTML documentation for this module issue the
command:

    pydoc -w foo

"""

class Foo(object):
    """
    Foo encapsulates a name and an age.
    """
    def __init__(self, name, age):
        """
        Construct a new 'Foo' object.

        :param name: The name of foo
        :param age: The ageof foo
        :return: returns nothing
        """
        self.name = name
        self.age = age

def bar(baz):
    """
    Prints baz to the display.
    """
    print baz

if __name__ == '__main__':
    f = Foo('John Doe', 42)
    bar("hello world")

The first docstring provides instructions for creating the documentation with pydoc. There are examples of different types of docstrings so you can see how they look when generated with pydoc.

I wanted to use the C++11 answer, but I could not because GCC 4.9 does not support std::put_time.

std::put_time implementation status in GCC?

I ended up using some C++11 to slightly improve the non-C++11 answer. For those that can't use GCC 5, but would still like some C++11 in their date/time format:

 std::array<char, 64> buffer;
 buffer.fill(0);
 time_t rawtime;
 time(&rawtime);
 const auto timeinfo = localtime(&rawtime);
 strftime(buffer.data(), sizeof(buffer), "%d-%m-%Y %H-%M-%S", timeinfo);
 std::string timeStr(buffer.data());

Actually, all of those examples on the web wherein the common content/file type like "js", "css", "img", etc is been used as library name are misleading.

Real world examples

To start, let's look at how existing JSF implementations like Mojarra and MyFaces and JSF component libraries like PrimeFaces and OmniFaces use it. No one of them use resource libraries this way. They use it (under the covers, by @ResourceDependency or UIViewRoot#addComponentResource()) the following way:

<h:outputScript library="javax.faces" name="jsf.js" />
<h:outputScript library="primefaces" name="jquery/jquery.js" />
<h:outputScript library="omnifaces" name="omnifaces.js" />
<h:outputScript library="omnifaces" name="fixviewstate.js" />
<h:outputScript library="omnifaces.combined" name="[dynamicname].js" />
<h:outputStylesheet library="primefaces" name="primefaces.css" />
<h:outputStylesheet library="primefaces-aristo" name="theme.css" />
<h:outputStylesheet library="primefaces-vader" name="theme.css" />

It should become clear that it basically represents the common library/module/theme name where all of those resources commonly belong to.

Easier identifying

This way it's so much easier to specify and distinguish where those resources belong to and/or are coming from. Imagine that you happen to have a primefaces.css resource in your own webapp wherein you're overriding/finetuning some default CSS of PrimeFaces; if PrimeFaces didn't use a library name for its own primefaces.css, then the PrimeFaces own one wouldn't be loaded, but instead the webapp-supplied one, which would break the look'n'feel.

Also, when you're using a custom ResourceHandler, you can also apply more finer grained control over resources coming from a specific library when library is used the right way. If all component libraries would have used "js" for all their JS files, how would the ResourceHandler ever distinguish if it's coming from a specific component library? Examples are OmniFaces CombinedResourceHandler and GraphicResourceHandler; check the createResource() method wherein the library is checked before delegating to next resource handler in chain. This way they know when to create CombinedResource or GraphicResource for the purpose.

Noted should be that RichFaces did it wrong. It didn't use any library at all and homebrewed another resource handling layer over it and it's therefore impossible to programmatically identify RichFaces resources. That's exactly the reason why OmniFaces CombinedResourceHander had to introduce a reflection-based hack in order to get it to work anyway with RichFaces resources.

Your own webapp

Your own webapp does not necessarily need a resource library. You'd best just omit it.

<h:outputStylesheet name="css/style.css" />
<h:outputScript name="js/script.js" />
<h:graphicImage name="img/logo.png" />

Or, if you really need to have one, you can just give it a more sensible common name, like "default" or some company name.

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

Or, when the resources are specific to some master Facelets template, you could also give it the name of the template, so that it's easier to relate each other. In other words, it's more for self-documentary purposes. E.g. in a /WEB-INF/templates/layout.xhtml template file:

<h:outputStylesheet library="layout" name="css/style.css" />
<h:outputScript library="layout" name="js/script.js" />

And a /WEB-INF/templates/admin.xhtml template file:

<h:outputStylesheet library="admin" name="css/style.css" />
<h:outputScript library="admin" name="js/script.js" />

For a real world example, check the OmniFaces showcase source code.

Or, when you'd like to share the same resources over multiple webapps and have created a "common" project for that based on the same example as in this answer which is in turn embedded as JAR in webapp's /WEB-INF/lib, then also reference it as library (name is free to your choice; component libraries like OmniFaces and PrimeFaces also work that way):

<h:outputStylesheet library="common" name="css/style.css" />
<h:outputScript library="common" name="js/script.js" />
<h:graphicImage library="common" name="img/logo.png" />

Library versioning

Another main advantage is that you can apply resource library versioning the right way on resources provided by your own webapp (this doesn't work for resources embedded in a JAR). You can create a direct child subfolder in the library folder with a name in the \d+(_\d+)* pattern to denote the resource library version.

WebContent
 |-- resources
 |    `-- default
 |         `-- 1_0
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

When using this markup:

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

This will generate the following HTML with the library version as v parameter:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_0" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_0"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_0" alt="" />

So, if you have edited/updated some resource, then all you need to do is to copy or rename the version folder into a new value. If you have multiple version folders, then the JSF ResourceHandler will automatically serve the resource from the highest version number, according to numerical ordering rules.

So, when copying/renaming resources/default/1_0/* folder into resources/default/1_1/* like follows:

WebContent
 |-- resources
 |    `-- default
 |         |-- 1_0
 |         |    :
 |         |
 |         `-- 1_1
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

Then the last markup example would generate the following HTML:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_1" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_1"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_1" alt="" />

This will force the webbrowser to request the resource straight from the server instead of showing the one with the same name from the cache, when the URL with the changed parameter is been requested for the first time. This way the endusers aren't required to do a hard refresh (Ctrl+F5 and so on) when they need to retrieve the updated CSS/JS resource.

Please note that library versioning is not possible for resources enclosed in a JAR file. You'd need a custom ResourceHandler. See also How to use JSF versioning for resources in jar.

Add a nodemon.json configuration file in your root folder and specify ignore patterns for example:

nodemon.json

{
  "ignore": [
    "*.test.js", 
    "dist/*"
  ]
}

• Note that by default .git, node_modules, bower_components, .nyc_output, coverage and .sass-cache are ignored so you don't need to add them to your configuration.

Explanation: This error happens because you exceeded the max number of watchers allowed by your system (i.e. nodemon has no more disk space to watch all the files - which probably means you are watching not important files). So you ignore non-important files that you don't care about changes in them for example the build output or the test cases.

You ignore case when you treat the data, not when you retrieve/store it. If you want to store everything in lowercase use String#toLowerCase, in uppercase use String#toUpperCase.

Then when you have to actually treat it, you may use out of the bow methods, like String#equalsIgnoreCase(java.lang.String). If nothing exists in the Java API that fulfill your needs, then you'll have to write your own logic.

Jonathan from the ExcelCentral forums suggests:

=WEEKNUM(A1,2)-WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),2)+1 

This formula extracts the week of the year [...] and then subtracts it from the week of the first day in the month to get the week of the month. You can change the day that weeks begin by changing the second argument of both WEEKNUM functions (set to 2 [for Monday] in the above example). For weeks beginning on Sunday, use:

=WEEKNUM(A1,1)-WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),1)+1

For weeks beginning on Tuesday, use:

=WEEKNUM(A1,12)-WEEKNUM(DATE(YEAR(A1),MONTH(A1),1),12)+1

etc.

I like it better because it's using the built in week calculation functionality of Excel (WEEKNUM).

Form1 OpenNewForm = new Form1();
OpenNewForm.Show();

"OpenNewForm" is the name of the Form. In the second the form opens.

If you want to close the previous form:

this.Close();

You should only have one <system.web> in your Web.Config Configuration File.

The CPU can only understand machine code indeed. For interpreted programs, the ultimate goal of an interpreter is to "interpret" the program code into machine code. However, usually a modern interpreted language does not interpret human code directly because it is too inefficient.

The Python interpreter first reads the human code and optimizes it to some intermediate code before interpreting it into machine code. That's why you always need another program to run a Python script, unlike in C++ where you can run the compiled executable of your code directly. For example, c:\Python27\python.exe or /usr/bin/python.

Your understanding is mostly correct. You use select_related when the object that you're going to be selecting is a single object, so OneToOneField or a ForeignKey. You use prefetch_related when you're going to get a "set" of things, so ManyToManyFields as you stated or reverse ForeignKeys. Just to clarify what I mean by "reverse ForeignKeys" here's an example:

class ModelA(models.Model):
    pass

class ModelB(models.Model):
    a = ForeignKey(ModelA)

ModelB.objects.select_related('a').all() # Forward ForeignKey relationship
ModelA.objects.prefetch_related('modelb_set').all() # Reverse ForeignKey relationship

The difference is that select_related does an SQL join and therefore gets the results back as part of the table from the SQL server. prefetch_related on the other hand executes another query and therefore reduces the redundant columns in the original object (ModelA in the above example). You may use prefetch_related for anything that you can use select_related for.

The tradeoffs are that prefetch_related has to create and send a list of IDs to select back to the server, this can take a while. I'm not sure if there's a nice way of doing this in a transaction, but my understanding is that Django always just sends a list and says SELECT ... WHERE pk IN (...,...,...) basically. In this case if the prefetched data is sparse (let's say U.S. State objects linked to people's addresses) this can be very good, however if it's closer to one-to-one, this can waste a lot of communications. If in doubt, try both and see which performs better.

Everything discussed above is basically about the communications with the database. On the Python side however prefetch_related has the extra benefit that a single object is used to represent each object in the database. With select_related duplicate objects will be created in Python for each "parent" object. Since objects in Python have a decent bit of memory overhead this can also be a consideration.

One more way to check existence of an element in a List

var result = myList.Exists(users => users.Equals("Vijai"))
         

Time conversion

To convert a time in one timezone to another timezone in Python, you could use datetime.astimezone():

so, below code is to convert the local time to other time zone.

• datetime.datetime.today() - return current the local time
• datetime.astimezone() - convert the time zone, but we have to pass the time zone.
• pytz.timezone('Asia/Kolkata') -passing the time zone to pytz module
• Strftime - Convert Datetime to string

# Time conversion from local time
import datetime
import pytz
dt_today = datetime.datetime.today()   # Local time
dt_India = dt_today.astimezone(pytz.timezone('Asia/Kolkata')) 
dt_London = dt_today.astimezone(pytz.timezone('Europe/London'))
India = (dt_India.strftime('%m/%d/%Y %H:%M'))
London = (dt_London.strftime('%m/%d/%Y %H:%M'))
print("Indian standard time: "+India+" IST")
print("British Summer Time: "+London+" BST")

list all the time zone

import pytz
for tz in pytz.all_timezones:
    print(tz)

Using set_time_limit(0) is useless when using php-fpm or similar process manager.

Bottomline is not to use set_time_limit when using php-fpm, to increase your execution timeout, check this tutorial.

When it comes to Muhammad Mehdi's answer, it is better to do:

private void salary_texbox_PreviewTextInput(object sender, TextCompositionEventArgs e)
{
     Regex regex = new Regex ( "[^0-9]+" );
     if(regex.IsMatch(e.Text))
     {
         MessageBox.Show("Error");
     }
}

Because when comparing with the TextCompositionEventArgs it gets also the last character, while with the textbox.Text it does not. With textbox, the error will show after next inserted character.

Date is Comparable & Equatable (as of Swift 3)

This answer complements @Ankit Thakur's answer.

Since Swift 3 the Date struct (based on the underlying NSDate class) adopts the Comparable and Equatable protocols.

• Comparable requires that Date implement the operators: <, <=, >, >=.
• Equatable requires that Date implement the == operator.
• Equatable allows Date to use the default implementation of the != operator (which is the inverse of the Equatable == operator implementation).

The following sample code exercises these comparison operators and confirms which comparisons are true with print statements.

Comparison function

import Foundation

func describeComparison(date1: Date, date2: Date) -> String {

    var descriptionArray: [String] = []

    if date1 < date2 {
        descriptionArray.append("date1 < date2")
    }

    if date1 <= date2 {
        descriptionArray.append("date1 <= date2")
    }

    if date1 > date2 {
        descriptionArray.append("date1 > date2")
    }

    if date1 >= date2 {
        descriptionArray.append("date1 >= date2")
    }

    if date1 == date2 {
        descriptionArray.append("date1 == date2")
    }

    if date1 != date2 {
        descriptionArray.append("date1 != date2")
    }

    return descriptionArray.joined(separator: ",  ")
}

Sample Use

let now = Date()

describeComparison(date1: now, date2: now.addingTimeInterval(1))
// date1 < date2,  date1 <= date2,  date1 != date2

describeComparison(date1: now, date2: now.addingTimeInterval(-1))
// date1 > date2,  date1 >= date2,  date1 != date2

describeComparison(date1: now, date2: now)
// date1 <= date2,  date1 >= date2,  date1 == date2

Officially google provide an Android API for this.

The API is currently being tested with a handful of partners, and will become available to all developers soon.

What worked for me is the following. I appears like the RMDir command will issue “The directory is not empty” nearly all the time...

:Cleanup_Temporary_Files_and_Folders

Erase /F /S /Q C:\MyDir

RMDir /S /Q C:\MyDir
If  Exist  C:\MyDir  GoTo Cleanup_Temporary_Files_and_Folders

From Docker 17.06 onwards, a special Mac-only DNS name is available in docker containers that resolves to the IP address of the host. It is:

docker.for.mac.localhost

The documentation is here: https://docs.docker.com/docker-for-mac/networking/#httphttps-proxy-support

There is an excellent answer provided by @Adem Öztas, for use with httplib and urllib2. For requests, if the question is strictly about resource existence, then the answer can be improved upon in the case of large resource existence.

The previous answer for requests suggested something like the following:

def uri_exists_get(uri: str) -> bool:
    try:
        response = requests.get(uri)
        try:
            response.raise_for_status()
            return True
        except requests.exceptions.HTTPError:
            return False
    except requests.exceptions.ConnectionError:
        return False

requests.get attempts to pull the entire resource at once, so for large media files, the above snippet would attempt to pull the entire media into memory. To solve this, we can stream the response.

def uri_exists_stream(uri: str) -> bool:
    try:
        with requests.get(uri, stream=True) as response:
            try:
                response.raise_for_status()
                return True
            except requests.exceptions.HTTPError:
                return False
    except requests.exceptions.ConnectionError:
        return False

I ran the above snippets with timers attached against two web resources:

1) http://bbb3d.renderfarming.net/download.html, a very light html page

2) http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_1080p_30fps_normal.mp4, a decently sized video file

Timing results below:

uri_exists_get("http://bbb3d.renderfarming.net/download.html")
# Completed in: 0:00:00.611239

uri_exists_stream("http://bbb3d.renderfarming.net/download.html")
# Completed in: 0:00:00.000007

uri_exists_get("http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_1080p_30fps_normal.mp4")
# Completed in: 0:01:12.813224

uri_exists_stream("http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_1080p_30fps_normal.mp4")
# Completed in: 0:00:00.000007

As a last note: this function also works in the case that the resource host doesn't exist. For example "http://abcdefghblahblah.com/test.mp4" will return False.

In addition to @chanafdo answer, you can use route name

when working with laravel blade

<a href="{{route('login')}}">login here</a> with parameter in route name

when go to url like URI: profile/{id} <a href="{{route('profile', ['id' => 1])}}">login here</a>

without blade

<a href="<?php echo route('login')?>">login here</a>

with parameter in route name

when go to url like URI: profile/{id} <a href="<?php echo route('profile', ['id' => 1])?>">login here</a>

As of laravel 5.2 you can use @php @endphp to create as <?php ?> in laravel blade. Using blade your personal opinion but I suggest to use it. Learn it. It has many wonderful features as template inheritance, Components & Slots,subviews etc...

int *generate_randomnumbers(int start, int end){
    int *res = malloc(sizeof(int)*(end-start));
    srand(time(NULL));
    for (int i= 0; i < (end -start)+1; i++){
        int r = rand()%end + start;
        int dup = 0;
        for (int j = 0; j < (end -start)+1; j++){
            if (res[j] == r){
                i--;
                dup = 1;
                break;
            }
        }
        if (!dup)
            res[i] = r;
    }
    return res;
}

Change your android version on your designer preview into your current version depend on your Manifest. rendering problem caused your designer preview used higher API level than your current android API level.

Adjust with your current API Level. If the API level isn't in the list, you'll need to install it via the SDK Manager.

if you don't want to use float

<div style="text-align:right; margin:0px auto 0px auto;">
<p> Hello </p>
</div>
  <div style="">
<p> Hello </p>
</div>

There's an important thing that people always seem to overlook:

You can pass a plain array to something which accepts an IList<T> parameter, and then you can call IList.Add() and will receive a runtime exception:

Unhandled Exception: System.NotSupportedException: Collection was of a fixed size.

For example, consider the following code:

private void test(IList<int> list)
{
    list.Add(1);
}

If you call that as follows, you will get a runtime exception:

int[] array = new int[0];
test(array);

This happens because using plain arrays with IList<T> violates the Liskov substitution principle.

For this reason, if you are calling IList<T>.Add() you may want to consider requiring a List<T> instead of an IList<T>.

Well, you don't specify if it's a 32 or 64 bit dll and you don't include the error message, but I'll guess that it's the same issue as described in this KB article: Error Message When You Run Regsvr32.exe on 64-Bit Windows

Quote from that article:

This behavior occurs because the Regsvr32.exe file in the System32 folder is a 64-bit version. When you run Regsvr32 to register a DLL, you are using the 64-bit version by default.

Solution from that article:

To resolve this issue, run Regsvr32.exe from the %SystemRoot%\Syswow64 folder. For example, type the following commands to register the DLL: cd \windows\syswow64 regsvr32 c:\filename.dll

It depends on the situation. If you're checking for something that may or may not have been defined globally outside your code (like jQuery perhaps) you want:

if (typeof(jQuery) != "undefined")

(No need for strict equality there, typeof always returns a string.) But if you have arguments to a function that may or may not have been passed, they'll always be defined, but null if omitted.

function sayHello(name) {
    if (name) return "Hello, " + name;
    else return "Hello unknown person";
}
sayHello(); // => "Hello unknown person"

<input name="date" type="text" (focus)="focusFunction()" (focusout)="focusOutFunction()">

works for me from Pardeep Jain

before comparing the two or more strings first execute the following commands

alter session set NLS_COMP=LINGUISTIC;
alter session set NLS_SORT=BINARY_CI;

after those two statements executed then you may compare the strings and there will be case insensitive.for example you had two strings s1='Apple' and s2='apple', if yow want to compare the two strings before executing the above statements then those two strings will be treated as two different strings but when you compare the strings after the execution of the two alter statements then those two strings s1 and s2 will be treated as the same string

reasons for using those two statements

We need to set NLS_COMP=LINGUISTIC and NLS_SORT=BINARY_CI in order to use 10gR2 case insensitivity. Since these are session modifiable, it is not as simple as setting them in the initialization parameters. We can set them in the initialization parameters but they then only affect the server and not the client side.

First, I am copying all values of arrays into a single array then I am removing duplicates values into the array. Line 12, explaining if same number occur more than time then put some extra garbage value into "j" position. At the end, traverse from start-end and check if same garbage value occur then discard.

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

    int arr1[]={1,3,3,2,4,2,3,3,5,2,1,99};
    int arr2[]={1,3,2,1,3,2,4,6,3,4};
    int arr3[]=new int[arr1.length+arr2.length];

    for(int i=0;i<arr1.length;i++)
        arr3[i]=arr1[i];

    for(int i=0;i<arr2.length;i++)
        arr3[arr1.length+i]=arr2[i];
    System.out.println(Arrays.toString(arr3));

    for(int i=0;i<arr3.length;i++)
    {
        for(int j=i+1;j<arr3.length;j++)
        {
            if(arr3[i]==arr3[j])
                arr3[j]=99999999;          //line  12
        }
    }
    for(int i=0;i<arr3.length;i++)
    {
        if(arr3[i]!=99999999)
            System.out.print(arr3[i]+" ");
    }
}   
}

You can access the code values for the characters in your string using the ord() built-in function. If you then need to format this in binary, the string.format() method will do the job.

a = "test"
print(' '.join(format(ord(x), 'b') for x in a))

(Thanks to Ashwini Chaudhary for posting that code snippet.)

While the above code works in Python 3, this matter gets more complicated if you're assuming any encoding other than UTF-8. In Python 2, strings are byte sequences, and ASCII encoding is assumed by default. In Python 3, strings are assumed to be Unicode, and there's a separate bytes type that acts more like a Python 2 string. If you wish to assume any encoding other than UTF-8, you'll need to specify the encoding.

In Python 3, then, you can do something like this:

a = "test"
a_bytes = bytes(a, "ascii")
print(' '.join(["{0:b}".format(x) for x in a_bytes]))

The differences between UTF-8 and ascii encoding won't be obvious for simple alphanumeric strings, but will become important if you're processing text that includes characters not in the ascii character set.

You have two issues in your code.. First you need reference to capture the element on click. Try adding another parameter to your function to reference this. Also active class is for li element initially while you are tryin to add it to "a" element in the function. try this..

<div class="row" style="padding-left:21px;">
 <ul class="nav nav-tabs" style="padding-left:40px;">
      <li class="active filter"><a href="#month" onclick="Data('month',this)">This Month</a></li>
      <li class="filter"><a href="#year" onclick="Data('year',this)">Year</a></li>
      <li class="filter"><a href="#last60"  onclick="Data('last60',this)">60 Days</a></li>
      <li class="filter"><a href="#last90"  onclick="Data('last90',this)">90 Days</a></li>
    </ul> 

</div>

<script>
  function Data(string,element)
    { 
      //1. get some data from server according to month year etc.,
      //2. unactive all the remaining li's and make the current clicked element active by adding "active" class to the element
      $('.filter').removeClass('active');

      $(element).parent().addClass('active') ;

    } 
</script>

You're missing quotes around the first value, it should be

INSERT INTO LOCATION VALUES('PQ95VM', 'HAPPY_STREET', 'FRANCE');

Incidentally, you'd be well-advised to specify the column names explicitly in the INSERT, for reasons of readability, maintainability and robustness, i.e.

INSERT INTO LOCATION (POSTCODE, STREET_NAME, CITY) VALUES ('PQ95VM', 'HAPPY_STREET', 'FRANCE');

I suggest an improvement of the Adam's answer accepting HashMap as parameter

/**
 * Append parameters to given url
 * @param url
 * @param parameters
 * @return new String url with given parameters
 * @throws URISyntaxException
 */
public static String appendToUrl(String url, HashMap<String, String> parameters) throws URISyntaxException
{
    URI uri = new URI(url);
    String query = uri.getQuery();

    StringBuilder builder = new StringBuilder();

    if (query != null)
        builder.append(query);

    for (Map.Entry<String, String> entry: parameters.entrySet())
    {
        String keyValueParam = entry.getKey() + "=" + entry.getValue();
        if (!builder.toString().isEmpty())
            builder.append("&");

        builder.append(keyValueParam);
    }

    URI newUri = new URI(uri.getScheme(), uri.getAuthority(), uri.getPath(), builder.toString(), uri.getFragment());
    return newUri.toString();
}

To make things clear and short

//raw.githubusercontent.com --> //rawgit.com

Note that this is handled by rawgit's development hosting and not their cdn for production hosting

I face the same problem while I have updated my SDK and Android studio version(3.0 beta). I have solved this problem going through this tutorial. In this they told us to update are build configuration file like

android {
   compileSdkVersion 26
   buildToolsVersion '26.0.0'
   defaultConfig {
   targetSdkVersion 26
  }
  ...
}

dependencies {
   compile 'com.android.support:appcompat-v7:26.0.0'
}

// REQUIRED: Google's new Maven repo is required for the latest
// support library that is compatible with Android 8.0
repositories {
   maven {
       url 'https://maven.google.com'
       // Alternative URL is 'https://dl.google.com/dl/android/maven2/'
   }
}

Hope it will help you out.

I think what you are looking for is to keep the background image fixed and just move the content on scroll. For that you have to simply use the following css property :

background-attachment: fixed;

Use ==:

pip install django_modeltranslation==0.4.0-beta2

This should help -

var json = "{'@STARTDATE': '2016-02-17 00:00:00.000',  '@ENDDATE': '2016-02-18 23:59:00.000' }";
var fdate = JObject.Parse(json)["@STARTDATE"];

You can do as the example on Mozilla docs:

 document.cookie = "someCookieName=true; expires=Fri, 31 Dec 9999 23:59:59 GMT";

P.S

Of course, there will be an issue if humanity still uses your code on the first minute of year 10000 :)

Following advice from comments I utilize Docker systemd documentation to improve this answer. Below procedure doesn't require reboot and is much cleaner.

First create directory and file for custom configuration:

sudo mkdir -p /etc/systemd/system/docker.service.d
sudo $EDITOR /etc/systemd/system/docker.service.d/docker-storage.conf

For docker version before 17.06-ce paste:

[Service]
ExecStart=
ExecStart=/usr/bin/docker daemon -H fd:// --graph="/mnt"

For docker after 17.06-ce paste:

[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H fd:// --data-root="/mnt"

Alternative method through daemon.json

I recently tried above procedure with 17.09-ce on Fedora 25 and it seem to not work. Instead of that simple modification in /etc/docker/daemon.json do the trick:

{
    "graph": "/mnt",
    "storage-driver": "overlay"
}

Despite the method you have to reload configuration and restart Docker:

sudo systemctl daemon-reload
sudo systemctl restart docker

To confirm that Docker was reconfigured:

docker info|grep "loop file"

In recent version (17.03) different command is required:

docker info|grep "Docker Root Dir"

Output should look like this:

 Data loop file: /mnt/devicemapper/devicemapper/data
 Metadata loop file: /mnt/devicemapper/devicemapper/metadata

Or:

 Docker Root Dir: /mnt

Then you can safely remove old Docker storage:

rm -rf /var/lib/docker

git push -f if you have permission, but that will screw up anyone else who pulls from that repo, so be careful.

If that is denied, and you have access to the server, as canzar says below, you can allow this on the server with

git config receive.denyNonFastForwards false

so if you have a table with a row like:

firstname lastname
Bill      smith

you can do something like

select firstname + ' ' + lastname from thetable

and you will get "Bill Smith"

   self.tableView.tableHeaderView = segmentedControl; 

If you want it to obey your width and height properly though enclose your segmentedControl in a UIView first as the tableView likes to mangle your view a bit to fit the width.

ps ax | grep tmux

17920 pts/11   S+     0:00 tmux a -t 13g2
18065 pts/19   S+     0:00 grep tmux

kill the other one.

Here is the full HTML that I use to center by button in Bootsrap form after closing form-group:

<div class="form-row text-center">
    <div class="col-12">
        <button type="submit" class="btn btn-primary">Submit</button>
    </div>
 </div>

In neither case can you modify a string literal, regardless of whether the pointer to that string literal is declared as char * or const char *.

However, the difference is that if the pointer is const char * then the compiler must give a diagnostic if you attempt to modify the pointed-to value, but if the pointer is char * then it does not.

Actually you don't even need a rewrite.

server {
    #listen 80 is default
    server_name www.example.com;
    return 301 $scheme://example.com$request_uri;
}

server {
    #listen 80 is default
    server_name example.com;
    ## here goes the rest of your conf...
}

As my answer is getting more and more up votes but the above as well. You should never use a rewrite in this context. Why? Because nginx has to process and start a search. If you use return (which should be available in any nginx version) it directly stops execution. This is preferred in any context.

Redirect both, non-SSL and SSL to their non-www counterpart:

server {
    listen               80;
    listen               443 ssl;
    server_name          www.example.com;
    ssl_certificate      path/to/cert;
    ssl_certificate_key  path/to/key;

    return 301 $scheme://example.com$request_uri;
}

server {
    listen               80;
    listen               443 ssl;
    server_name          example.com;
    ssl_certificate      path/to/cert;
    ssl_certificate_key  path/to/key;

    # rest goes here...
}

The $scheme variable will only contain http if your server is only listening on port 80 (default) and the listen option does not contain the ssl keyword. Not using the variable will not gain you any performance.

Note that you need even more server blocks if you use HSTS, because the HSTS headers should not be sent over non-encrypted connections. Hence, you need unencrypted server blocks with redirects and encrypted server blocks with redirects and HSTS headers.

Redirect everything to SSL (personal config on UNIX with IPv4, IPv6, SPDY, ...):

#
# Redirect all www to non-www
#
server {
    server_name          www.example.com;
    ssl_certificate      ssl/example.com/crt;
    ssl_certificate_key  ssl/example.com/key;
    listen               *:80;
    listen               *:443 ssl spdy;
    listen               [::]:80 ipv6only=on;
    listen               [::]:443 ssl spdy ipv6only=on;

    return 301 https://example.com$request_uri;
}

#
# Redirect all non-encrypted to encrypted
#
server {
    server_name          example.com;
    listen               *:80;
    listen               [::]:80;

    return 301 https://example.com$request_uri;
}

#
# There we go!
#
server {
    server_name          example.com;
    ssl_certificate      ssl/example.com/crt;
    ssl_certificate_key  ssl/example.com/key;
    listen               *:443 ssl spdy;
    listen               [::]:443 ssl spdy;

    # rest goes here...
}

I guess you can imagine other compounds with this pattern now by yourself.

Minimal example that generates the error

main.S moves an address into %eax (32-bit).

main.S

_start:
    mov $_start, %eax

linker.ld

SECTIONS
{
    /* This says where `.text` will go in the executable. */
    . = 0x100000000;
    .text :
    {
        *(*)
    }
}

Compile on x86-64:

as -o main.o main.S
ld -o main.out -T linker.ld main.o

Outcome of ld:

(.text+0x1): relocation truncated to fit: R_X86_64_32 against `.text'

Keep in mind that:

• as puts everything on the .text if no other section is specified
• ld uses the .text as the default entry point if ENTRY. Thus _start is the very first byte of .text.

How to fix it: use this linker.ld instead, and subtract 1 from the start:

SECTIONS
{
    . = 0xFFFFFFFF;
    .text :
    {
        *(*)
    }
}

Notes:

• we cannot make _start global in this example with .global _start, otherwise it still fails. I think this happens because global symbols have alignment constraints (0xFFFFFFF0 works). TODO where is that documented in the ELF standard?

• the .text segment also has an alignment constraint of p_align == 2M. But our linker is smart enough to place the segment at 0xFFE00000, fill with zeros until 0xFFFFFFFF and set e_entry == 0xFFFFFFFF. This works, but generates an oversized executable.

Tested on Ubuntu 14.04 AMD64, Binutils 2.24.

Explanation

First you must understand what relocation is with a minimal example: https://stackoverflow.com/a/30507725/895245

Next, take a look at objdump -Sr main.o:

0000000000000000 <_start>:
   0:   b8 00 00 00 00          mov    $0x0,%eax
                        1: R_X86_64_32  .text

If we look into how instructions are encoded in the Intel manual, we see that:

• b8 says that this is a mov to %eax
• 0 is an immediate value to be moved to %eax. Relocation will then modify it to contain the address of _start.

When moving to 32-bit registers, the immediate must also be 32-bit.

But here, the relocation has to modify those 32-bit to put the address of _start into them after linking happens.

0x100000000 does not fit into 32-bit, but 0xFFFFFFFF does. Thus the error.

This error can only happen on relocations that generate truncation, e.g. R_X86_64_32 (8 bytes to 4 bytes), but never on R_X86_64_64.

And there are some types of relocation that require sign extension instead of zero extension as shown here, e.g. R_X86_64_32S. See also: https://stackoverflow.com/a/33289761/895245

R_AARCH64_PREL32

Asked at: How to prevent "main.o:(.eh_frame+0x1c): relocation truncated to fit: R_AARCH64_PREL32 against `.text'" when creating an aarch64 baremetal program?

$path = "C:\temp\NewFolder"
If(!(test-path $path))
{
      New-Item -ItemType Directory -Force -Path $path
}

Test-Path checks to see if the path exists. When it does not, it will create a new directory.

For MySQL, there is none: MySQL Feature Request.

Allowing this is arguably a really bad idea, anyway: IF EXISTS indicates that you're running destructive operations on a database with (to you) unknown structure. There may be situations where this is acceptable for quick-and-dirty local work, but if you're tempted to run such a statement against production data (in a migration etc.), you're playing with fire.

But if you insist, it's not difficult to simply check for existence first in the client, or to catch the error.

MariaDB also supports the following starting with 10.0.2:

DROP [COLUMN] [IF EXISTS] col_name 

i. e.

ALTER TABLE my_table DROP IF EXISTS my_column;

But it's arguably a bad idea to rely on a non-standard feature supported by only one of several forks of MySQL.

Try out cat and sprintf in your for loop.

eg.

cat(sprintf("\"%f\" \"%f\"\n", df$r, df$interest))

See here

A 128-bit MD5 hash is represented as a sequence of 32 hexadecimal digits.

SELECT t1.credit, 
       t2.debit 
FROM   (SELECT Sum(c.total_amount) AS credit 
        FROM   credit c 
        WHERE  c.status = "a") AS t1, 
       (SELECT Sum(d.total_amount) AS debit 
        FROM   debit d 
        WHERE  d.status = "a") AS t2 

For those that like to work with small numbers

const today = new Date();
const endDate = new Date(startDate.setDate(startDate.getDate() + 7));
const days = parseInt((endDate - today) / (1000 * 60 * 60 * 24));
const hours = parseInt(Math.abs(endDate - today) / (1000 * 60 * 60) % 24);
const minutes = parseInt(Math.abs(endDate.getTime() - today.getTime()) / (1000 * 60) % 60);
const seconds = parseInt(Math.abs(endDate.getTime() - today.getTime()) / (1000) % 60); 

new Date().getTime();

For more information, see @James McMahon's answer.

for (int i = 0; i < 8; i++)

It's a for loop, which will execute the next statement a number of times, depending on the conditions inside the parenthesis.

for (int i = 0; i < 8; i++)

Start by setting i = 0

for (int i = 0; i < 8; i++)

Continue looping while i < 8.

for (int i = 0; i < 8; i++)

Every time you've been around the loop, increase i by 1.

For example;

for (int i = 0; i < 8; i++)
    do(i);

will call do(0), do(1), ... do(7) in order, and stop when i reaches 8 (ie i < 8 is false)

You can add it to your shell configuration file, e.g. $HOME/.bashrc or more globally in /etc/environment. After adding these lines the changes won't reflect instantly in GUI based system's you have to exit the terminal or create a new one and in server logout the session and login to reflect these changes.

Make the div

runat="server" 

and do

if (lstFilePrefix1.SelectedValue=="Prefix2")
{
    int TotalRows = this.BindList(1);
    this.Prepare_Pager(TotalRows);
    data.Style["display"] = "block";
}

Your method isn't working because the javascript is being rendered in the top of the body tag, before the div is rendered. You'd have to include code to tell the javascript to wait for the DOM to be completely ready to take on your request, which would probably be easiest to do with jQuery.

If there is a package.json, and in it there is lodash configuration in it. then you should:

npm install

if in the package.json there is no lodash:

npm install --save-dev

what about

public class CmdExec {

public static Scanner s = null;


public static void main(String[] args) throws InterruptedException, IOException {
    s = new Scanner(System.in);
    System.out.print("$ ");
    String cmd = s.nextLine();
    final Process p = Runtime.getRuntime().exec(cmd);

    new Thread(new Runnable() {
        public void run() {
            BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
            String line = null; 

            try {
                while ((line = input.readLine()) != null) {
                    System.out.println(line);
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }).start();

    p.waitFor();
     }

 }

It's a linker problem. Include the static library path into your project.

For Qt Creator open the project file .pro and add the following line:

LIBS += -L<path for boost libraries in the system> -lboost_system

In my case Ubuntu x86_64:

LIBS += -L/usr/lib/x86_64-linux-gnu -lboost_system

For Codeblocks, open up Settings->Compiler...->Linker settings tab and add:

boost_system

to the Link libraries text widget and press OK button.

I was trying to put together some JavaScript to validate a domain name (ex. google.com) and if it validates enable a submit button. I thought that I would share my code for those who are looking to accomplish something similar. It expects a domain without any http:// or www. value. The script uses a stripped down regular expression from above for domain matching, which isn't strict about fake TLD.

http://jsfiddle.net/nMVDS/1/

$(function () {
  $('#whitelist_add').keyup(function () {
    if ($(this).val() == '') { //Check to see if there is any text entered
        //If there is no text within the input, disable the button
        $('.whitelistCheck').attr('disabled', 'disabled');
    } else {
        // Domain name regular expression
        var regex = new RegExp("^([0-9A-Za-z-\\.@:%_\+~#=]+)+((\\.[a-zA-Z]{2,3})+)(/(.)*)?(\\?(.)*)?");
        if (regex.test($(this).val())) {
            // Domain looks OK
            //alert("Successful match");
            $('.whitelistCheck').removeAttr('disabled');
        } else {
            // Domain is NOT OK
            //alert("No match");
            $('.whitelistCheck').attr('disabled', 'disabled');
        }
    }
  });
});

HTML FORM:

<form action="domain_management.php" method="get">
    <input type="text" name="whitelist_add" id="whitelist_add" placeholder="domain.com">
    <button type="submit" class="btn btn-success whitelistCheck" disabled='disabled'>Add to Whitelist</button>
</form>

In your destination field you want to use VLOOKUP like so:

=VLOOKUP(Sheet1!A1:A100,Sheet2!A1:F100,6,FALSE)

VLOOKUP Arguments:

1. The set fields you want to lookup.
2. The table range you want to lookup up your value against. The first column of your defined table should be the column you want compared against your lookup field. The table range should also contain the value you want to display (Column F).
3. This defines what field you want to display upon a match.
4. FALSE tells VLOOKUP to do an exact match.

If you want to write unit per meter (m^-1), use $m^{-1}$), which means -1 inbetween {}

Example: plt.ylabel("Specific Storage Values ($m^{-1}$)", fontsize = 12 )

By alphabetical-order I assume the order to be : A|a < B|b < C|c... Hope this is what @Nick is(or was) looking for and the answer follows the above assumption.

I would suggest to have a class implement compare method of Comparator-interface as :

public int compare(Object o1, Object o2) {
    return o1.toString().compareToIgnoreCase(o2.toString());
}

and from the calling method invoke the Arrays.sort method with custom Comparator as :

Arrays.sort(inputArray, customComparator);

Observed results: input Array : "Vani","Kali", "Mohan","Soni","kuldeep","Arun"

output(Alphabetical-order) is : Arun, Kali, kuldeep, Mohan, Soni, Vani

Output(Natural-order by executing Arrays.sort(inputArray) is : Arun, Kali, Mohan, Soni, Vani, kuldeep

Thus in case of natural ordering, [Vani < kuldeep] which to my understanding of alphabetical-order is not the thing desired.

for more understanding of natural and alphabetical/lexical order visit discussion here

Beside the above good arguments, I will add that lot of people today see switch as an obsolete remainder of procedural past of Java (back to C times).

I don't fully share this opinion, I think switch can have its usefulness in some cases, at least because of its speed, and anyway it is better than some series of cascading numerical else if I saw in some code...

But indeed, it is worth looking at the case where you need a switch, and see if it cannot be replaced by something more OO. For example enums in Java 1.5+, perhaps HashTable or some other collection (sometime I regret we don't have (anonymous) functions as first class citizen, as in Lua — which doesn't have switch — or JavaScript) or even polymorphism.

You should create an Intent object with a geo-URI:

String uri = String.format(Locale.ENGLISH, "geo:%f,%f", latitude, longitude);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
context.startActivity(intent);

If you want to specify an address, you should use another form of geo-URI: geo:0,0?q=address.

Here is how a UTF8 text file can be read from a zip archive into a string variable (.NET Framework 4.5 and up):

string zipFileFullPath = "{{TypeYourZipFileFullPathHere}}";
string targetFileName = "{{TypeYourTargetFileNameHere}}";
string text = new string(
            (new System.IO.StreamReader(
             System.IO.Compression.ZipFile.OpenRead(zipFileFullPath)
             .Entries.Where(x => x.Name.Equals(targetFileName,
                                          StringComparison.InvariantCulture))
             .FirstOrDefault()
             .Open(), Encoding.UTF8)
             .ReadToEnd())
             .ToArray());

In a decorator method, you can list arguments of the original method in this way:

import inspect, itertools 

def my_decorator():

        def decorator(f):

            def wrapper(*args, **kwargs):

                # if you want arguments names as a list:
                args_name = inspect.getargspec(f)[0]
                print(args_name)

                # if you want names and values as a dictionary:
                args_dict = dict(itertools.izip(args_name, args))
                print(args_dict)

                # if you want values as a list:
                args_values = args_dict.values()
                print(args_values)

If the **kwargs are important for you, then it will be a bit complicated:

        def wrapper(*args, **kwargs):

            args_name = list(OrderedDict.fromkeys(inspect.getargspec(f)[0] + kwargs.keys()))
            args_dict = OrderedDict(list(itertools.izip(args_name, args)) + list(kwargs.iteritems()))
            args_values = args_dict.values()

Example:

@my_decorator()
def my_function(x, y, z=3):
    pass


my_function(1, y=2, z=3, w=0)
# prints:
# ['x', 'y', 'z', 'w']
# {'y': 2, 'x': 1, 'z': 3, 'w': 0}
# [1, 2, 3, 0]

A 101x101 QR code, with high level error correction, can hold 3248 bits, or 406 bytes. Probably not enough for any meaningful SVG/XML data.

A 177x177 grid, depending on desired level of error correction, can store between 1273 and 2953 bytes. Maybe enough to store something small.

On windows you can use a graphic interface of scp using winSCP. A nice free software that implements SFTP protocol.

You can manage selecting those elements without any form of regex as the previous answers show, but to answer the question directly, yes you can use a form of regex in selectors:

#sections div[id^='s'] {
    color: red;  
}

That says select any div elements inside the #sections div that have an ID starting with the letter 's'.

Today I installed Wamp server 3.0.6 (x64) on a Windows 10 machine with VS2017 installed. I had many Visual C++ Redistributable Packages installed, but not the 2012 one. Then I installed it and now I can run the Wamp server. You can find a download link here.

I know this is old, but maybe this will help someone else.

Do not log "new" values. Your existing table, GUESTS, has the new values. You'll have double entry of data, plus your DB size will grow way too fast that way.

I cleaned this up and minimized it for this example, but here is the tables you'd need for logging off changes:

CREATE TABLE GUESTS (
      GuestID INT IDENTITY(1,1) PRIMARY KEY, 
      GuestName VARCHAR(50), 
      ModifiedBy INT, 
      ModifiedOn DATETIME
)

CREATE TABLE GUESTS_LOG (
      GuestLogID INT IDENTITY(1,1) PRIMARY KEY, 
      GuestID INT, 
      GuestName VARCHAR(50), 
      ModifiedBy INT, 
      ModifiedOn DATETIME
)

When a value changes in the GUESTS table (ex: Guest name), simply log off that entire row of data, as-is, to your Log/Audit table using the Trigger. Your GUESTS table has current data, the Log/Audit table has the old data.

Then use a select statement to get data from both tables:

SELECT 0 AS 'GuestLogID', GuestID, GuestName, ModifiedBy, ModifiedOn FROM [GUESTS] WHERE GuestID = 1
UNION
SELECT GuestLogID, GuestID, GuestName, ModifiedBy, ModifiedOn FROM [GUESTS_LOG] WHERE GuestID = 1
ORDER BY ModifiedOn ASC

Your data will come out with what the table looked like, from Oldest to Newest, with the first row being what was created & the last row being the current data. You can see exactly what changed, who changed it, and when they changed it.

Optionally, I used to have a function that looped through the RecordSet (in Classic ASP), and only displayed what values had changed on the web page. It made for a GREAT audit trail so that users could see what had changed over time.

find . | grep -v "excluded files criteria" | xargs rm

This will list all files in current directory, then list all those that don't match your criteria (beware of it matching directory names) and then remove them.

Update: based on your edit, if you really want to delete everything from current directory except files you listed, this can be used:

mkdir /tmp_backup && mv textfile.txt backup.tar.gz script.php database.sql info.txt /tmp_backup/ && rm -r && mv /tmp_backup/* . && rmdir /tmp_backup

It will create a backup directory /tmp_backup (you've got root privileges, right?), move files you listed to that directory, delete recursively everything in current directory (you know that you're in the right directory, do you?), move back to current directory everything from /tmp_backup and finally, delete /tmp_backup.

I choose the backup directory to be in root, because if you're trying to delete everything recursively from root, your system will have big problems.

Surely there are more elegant ways to do this, but this one is pretty straightforward.

Not sure if people are still looking for simple solutions to this, but you are able to run multiple instances of the "Collection Runner" in Postman. Just create a runner with some requests and click the "Run" button multiple times to bring up multiple instances.

I'm not a WCF expert but I'm wondering if you aren't running into a DDOS protection on IIS. I know from experience that if you run a bunch of simultaneous connections from a single client to a server at some point the server stops responding to the calls as it suspects a DDOS attack. It will also hold the connections open until they time-out in order to slow the client down in his attacks.

Multiple connection coming from different machines/IP's should not be a problem however.

I had this problem with storyboard and swift class for ui view controller. Solved it by using the @objc directive:

This is more of an xpath question, but like this, assuming the context is the parent element:

<xsl:value-of select="name/@attribute1" />

For the benefit of anyone else reading this question that really is missing print statements from their output, there actually are cases where the print executes but is not returned to the client. I can't tell you specifically what they are. I can tell you that if put a go statement immediately before and after any print statement, you will see it if it is executed.

For converting an entire xml document to a pretty xml document
(ex: assuming you've extracted [unzipped] a LibreOffice Writer .odt or .ods file, and you want to convert the ugly "content.xml" file to a pretty one for automated git version control and git difftooling of .odt/.ods files, such as I'm implementing here)

import xml.dom.minidom

file = open("./content.xml", 'r')
xml_string = file.read()
file.close()

parsed_xml = xml.dom.minidom.parseString(xml_string)
pretty_xml_as_string = parsed_xml.toprettyxml()

file = open("./content_new.xml", 'w')
file.write(pretty_xml_as_string)
file.close()

You can do something like this:

public class Example
{
    public String name;
    public String location;

    public String[] getExample()
    {
        String ar[] = new String[2];
        ar[0]= name;
        ar[1] =  location;
        return ar; //returning two values at once
    }
}

Unless there is some compelling reason to use a regex, I would just use String.startsWith:

bool matches = test.startsWith("http://")
            || test.startsWith("https://") 
            || test.startsWith("ftp://");

I wouldn't be surprised if this is faster, too.

None of these worked for me. I converted the first element to be part of a series (a single element series), and converted the second element also to be a series, and used append function.

l = ((pd.Series(<first element>)).append(pd.Series(<list of other elements>))).tolist()

You can remove the duplicate elements with the uniq method:

array.uniq  # => [1, 2, 4, 5, 6, 7, 8]

What might also be useful to know is that uniq takes a block, so if you have a have an array of keys:

["bucket1:file1", "bucket2:file1", "bucket3:file2", "bucket4:file2"]

and you want to know what the unique files are, you can find it out with:

a.uniq { |f| f[/\d+$/] }.map { |p| p.split(':').last }

The code you pasted should work... There must be something else we are not seeing here.

"an object" of what type?

You can certainly assign NULL (and nullptr) to objects of pointer types, and it is implementation defined if you can assign NULL to objects of arithmetic types.

If you mean objects of some class type, the answer is NO (excepting classes that have operator= accepting pointer or arithmetic types)

"empty" is more plausible, as many types have both copy assignment and default construction (often implicitly). To see if an existing object is like a default constructed one, you will also need an appropriate bool operator==

Preflight is a web security feature implemented by the browser. For Chrome you can disable all web security by adding the --disable-web-security flag.

For example: "C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="C:\newChromeSettingsWithoutSecurity" . You can first create a new shortcut of chrome, go to its properties and change the target as above. This should help!
