Simply add $autoload['helper'] = array('url'); to autoload.php.

Here is a very useful and lightweight javascript plugin to accomplish this: js-cookie

Cookies.set('cookieName', 'Value');
      setTimeout(function(){
        var cookieValue =  Cookies.get('cookieName');
        if(cookieValue){
           console.log("Test Cookie is set!");
        } else {
           document.write('<p>Sorry, but cookies must be enabled</p>');
        }
        Cookies.remove('cookieName');
      }, 1000);

Works in all browsers, accepts any character.

In Build: v22.6.2-1085508 ADT you need to add(select Android 4.4.2)

Goto project --> properties --> Android(This is second in listed item order leftPanel) and in the RightPanel Project Build Target, select Android 4.4.2 as Target name and apply changes It will rebuild the workspace.

In my case unable to resolve target 'android-17' eclipse was being shown as compile error and in code: import java.util.HashMap was not being referenced.

Update in 2020 in Php7:

there is a better way to do this using the Null coalescing operator by just doing the following:

$data[$parts[0]] = $parts[1] ?? null;

I was able to use nginx to handle the 301 redirect to the aws signin page.

Go to your nginx conf folder (in my case it's /etc/nginx/sites-available in which I create a symlink to /etc/nginx/sites-enabled for the enabled conf files).

Then add a redirect path

server {
  listen 80;
  server_name aws.example.com;
  return 301 https://myaccount.signin.aws.amazon.com/console;
}

If you are using nginx, you will most likely have additional server blocks (virtualhosts in apache terminology) to handle your zone apex (example.com) or however you have it setup. Make sure that you have one of them set to be your default server.

server {
  listen 80 default_server;
  server_name example.com;
  # rest of config ...
}

In Route 53, add an A record for aws.example.com and set the value to the same IP used for your zone apex.

Displaying an image from MySql Db.

$db = mysqli_connect("localhost","root","","DbName"); 
$sql = "SELECT * FROM products WHERE id = $id";
$sth = $db->query($sql);
$result=mysqli_fetch_array($sth);
echo '<img src="data:image/jpeg;base64,'.base64_encode( $result['image'] ).'"/>';

Here is the script that I use. With it, I avoid unnecessarily dropping and recreating the stored procs.

IF NOT EXISTS (
    SELECT *
    FROM sys.objects
    WHERE object_id = OBJECT_ID(N'[dbo].[uspMyProcedure]')
    )
BEGIN
  EXEC sp_executesql N'CREATE PROCEDURE [dbo].[uspMyProcedure] AS select 1'
END
GO

ALTER PROCEDURE [dbo].[uspMyProcedure] 
    @variable1 INTEGER  
AS
BEGIN
   -- Stored procedure logic
END

There are several helpful bits of code for this.

Place your cursor in a merged cell and ask these questions in the Immidiate Window:

Is the activecell a merged cell?

? Activecell.Mergecells
 True

How many cells are merged?

? Activecell.MergeArea.Cells.Count
 2

How many columns are merged?

? Activecell.MergeArea.Columns.Count
 2

How many rows are merged?

? Activecell.MergeArea.Rows.Count
  1

What's the merged range address?

? activecell.MergeArea.Address
  $F$2:$F$3

I find this useful for queries, especially if they use aggregates or several tables (SQL Server)

DECLARE @query nvarchar(max) = 'select * from yourtable';
EXEC sp_describe_first_result_set @query, null, 0; 

I think the xpath query you want goes something like this:

/xml/box[@stepId="$stepId"]/components/component[@id="$componentId"]/variables/variable[@nom="Enabled" and @valeur="Yes"]

This should get you the variables that are named "Enabled" with a value of "Yes" for the specified $stepId and $componentId. This is assuming that your xml starts with an tag like you show, and not

If the SQL Server 2005 XPath stuff is pretty straightforward (I've never used it), then the above query should work. Otherwise, someone else may have to help you with that.

You can use Uber's H3,point_dist() function to compute the spherical distance between two (lat, lng) points. We can set return unit ('km', 'm', or 'rads'). The default unit is Km.

Example :

import H3

coords_1 = (52.2296756, 21.0122287)
coords_2 = (52.406374, 16.9251681)
distance = h3.point_dist(coords_1,coords_2) #278.4584889328128

Hope this will usefull!

The problem was the box "open new connection" that was checked. So I couldn't use my temporary table.

Building on Oded's answer, you could also set the default option but not make it a selectable option if it's just dummy text. For example you could do:

<option selected="selected" disabled="disabled">Select a language</option>

This would show "Select a language" before the user clicks the select box but the user wouldn't be able to select it because of the disabled attribute.

Since 2017 and Symfony 3.3 you can register Repository as service, with all its advantages it has.

Check my post How to use Repository with Doctrine as Service in Symfony for more general description.

To your specific case, original code with tuning would look like this:

1. Use in your services or Controller

<?php

namespace Test\CommonBundle\Services;

use Doctrine\ORM\EntityManagerInterface;

class UserService
{
    private $userRepository;

    // use custom repository over direct use of EntityManager
    // see step 2
    public function __constructor(UserRepository $userRepository)
    {
        $this->userRepository = $userRepository;
    }

    public function getUser($userId)
    {
        return $this->userRepository->find($userId);
    }
}

2. Create new custom repository

<?php

namespace Test\CommonBundle\Repository;

use Doctrine\ORM\EntityManagerInterface;

class UserRepository
{
    private $repository;

    public function __construct(EntityManagerInterface $entityManager)
    {
        $this->repository = $entityManager->getRepository(UserEntity::class);
    }

    public function find($userId)
    {
        return  $this->repository->find($userId);
    }
}

3. Register services

# app/config/services.yml
services:
    _defaults:
        autowire: true

    Test\CommonBundle\:
       resource: ../../Test/CommonBundle

Instagram developer console has provided the solution for it. https://www.instagram.com/developer/endpoints/

To use this in PHP, here is the code snippet,

/**
**
** Add this code snippet after your first curl call
** assume the response of the first call is stored in $userdata
** $access_token have your access token
*/

$maximumNumberOfPost = 33; // it can be 20, depends on your instagram application
$no_of_images = 50 // Enter the number of images you want

if ($no_of_images > $maximumNumberOfPost) {

    $ImageArray = [];
    $next_url = $userdata->pagination->next_url;
    while ($no_of_images > $maximumNumberOfPost) {
           $originalNumbersOfImage = $no_of_images;
           $no_of_images = $no_of_images - $maximumNumberOfPost;
           $next_url = str_replace("count=" . $originalNumbersOfImage, "count=" . $no_of_images, $next_url);
           $chRepeat = curl_init();
           curl_setopt_array($chRepeat, [
                             CURLOPT_URL => $next_url,
                             CURLOPT_HTTPHEADER => [
                                    "Authorization: Bearer $access_token"
                              ],
                              CURLOPT_RETURNTRANSFER => true
                            ]);
            $userRepeatdata = curl_exec($chRepeat);
            curl_close($chRepeat);
            if ($userRepeatdata) {
                      $userRepeatdata = json_decode($userRepeatdata);
                      $next_url = $userRepeatdata->pagination->next_url;
                     if (isset($userRepeatdata->data) && $userRepeatdata->data) {
                          $ImageArray = $userRepeatdata->data;
                   }
           }
    }

}

This helped me delete data based on different attributes. This is dangerous so make sure you back up database or the table before doing it:

mysqldump -h hotsname -u username -p password database_name > backup_folder/backup_filename.txt

Now you can perform the delete operation:

delete from table_name where column_name < DATE_SUB(NOW() , INTERVAL 1 DAY)

This will remove all the data from before one day. For deleting data from before 6 months:

delete from table_name where column_name < DATE_SUB(NOW() , INTERVAL 6 MONTH)

If you only have two choices to select from:

df['color'] = np.where(df['Set']=='Z', 'green', 'red')

For example,

import pandas as pd
import numpy as np

df = pd.DataFrame({'Type':list('ABBC'), 'Set':list('ZZXY')})
df['color'] = np.where(df['Set']=='Z', 'green', 'red')
print(df)

yields

  Set Type  color
0   Z    A  green
1   Z    B  green
2   X    B    red
3   Y    C    red

If you have more than two conditions then use np.select. For example, if you want color to be

• yellow when (df['Set'] == 'Z') & (df['Type'] == 'A')
• otherwise blue when (df['Set'] == 'Z') & (df['Type'] == 'B')
• otherwise purple when (df['Type'] == 'B')
• otherwise black,

then use

df = pd.DataFrame({'Type':list('ABBC'), 'Set':list('ZZXY')})
conditions = [
    (df['Set'] == 'Z') & (df['Type'] == 'A'),
    (df['Set'] == 'Z') & (df['Type'] == 'B'),
    (df['Type'] == 'B')]
choices = ['yellow', 'blue', 'purple']
df['color'] = np.select(conditions, choices, default='black')
print(df)

which yields

  Set Type   color
0   Z    A  yellow
1   Z    B    blue
2   X    B  purple
3   Y    C   black

For the Scripting.Dictionary type, you can either use late binding (as already pointed out ) with:

Dim Dict as Object
Set Dict = CreateObject("Scripting.Dictionary")

Which works, but you don't get the code auto completion. Or you use early binding, but you need to make sure that VBA can find the Scripting.Dictionary type by adding the reference to the Microsoft Scripting Library via VBA-->Tools-->References--> "Microsoft Scripting Runtime". Then you can use:

Dim Dict as Scripting.Dictionary
Set Dict = New Scripting.Dictionary

... and auto completion will work.

Why not do it XAML?

<ComboBox x:Name="myComboBoxMenu" PlaceholderText="Hello"/>

Some compilers might create issues with this - on a Mac C++ compiler, EXIT_SUCCESS worked fine for me but on a Linux C++ complier I had to add cstdlib for it to know what EXIT_SUCCESS is. Other than that, they are one and the same.

Eric answer is correct, but the problem is the fields are not grouped. Imagine you have multiple streets and cities which belong together:

<h1>First Address</h1>
<input name="street[]" value="Hauptstr" />
<input name="city[]" value="Berlin"  />

<h2>Second Address</h2>
<input name="street[]" value="Wallstreet" />
<input name="city[]" value="New York" />

The outcome would be

$POST = [ 'street' => [ 'Hauptstr', 'Wallstreet'], 
          'city' => [ 'Berlin' , 'New York'] ];

To group them by address, I would rather recommend to use what Eric also mentioned in the comment section:

<h1>First Address</h1>
<input name="address[1][street]" value="Hauptstr" />
<input name="address[1][city]" value="Berlin"  />

<h2>Second Address</h2>
<input name="address[2][street]" value="Wallstreet" />
<input name="address[2][city]" value="New York" />

The outcome would be

$POST = [ 'address' => [ 
                 1 => ['street' => 'Hauptstr', 'city' => 'Berlin'],
                 2 => ['street' => 'Wallstreet', 'city' => 'New York'],
              ]
        ]

If you're using Oracle, then a feature called analytics will do the trick. It looks like this:

select id, age, count(*) over (partition by age) from students;

If you aren't using Oracle, then you'll need to join back to the counts:

select a.id, a.age, b.age_count
  from students a
  join (select age, count(*) as age_count
          from students
         group by age) b
    on a.age = b.age

I ran into another situation where this can occur. I work with a team we use Xcode server for continuous integration. The server wasn't seeing any simulators, but only for one project. I eventually determined that this was due to the fact that the version of Xcode on our server was one release earlier, and the Xcode project was set to build to the newest version available. Simply updating Xcode solved the issue for us.

I always use the word var in web articles or guides writings.

The width of the text editor of online article is small.

If I write this:

SomeCoolNameSpace.SomeCoolClassName.SomeCoolSubClassName coolClass = new SomeCoolNameSpace.SomeCoolClassName.SomeCoolSubClassName();

You will see that above rendered pre code text is too long and flows out of the box, it gets hidden. The reader needs to scroll to the right to see the complete syntax.

That's why I always use the keyword var in web article writings.

var coolClass = new SomeCoolNameSpace.SomeCoolClassName.SomeCoolSubClassName();

The whole rendered pre code just fit within the screen.

In practice, for declaring object, I seldom use var, I rely on intellisense to declare object faster.

Example:

SomeCoolNamespace.SomeCoolObject coolObject = new SomeCoolNamespace.SomeCoolObject();

But, for returning object from a method, I use var to write code faster.

Example:

var coolObject = GetCoolObject(param1, param2);

Try this:

implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'

I think the advantages are:

1. Web development in a dynamic language (JavaScript) on a VM that is incredibly fast (V8). It is much faster than Ruby, Python, or Perl.

2. Ability to handle thousands of concurrent connections with minimal overhead on a single process.

3. JavaScript is perfect for event loops with first class function objects and closures. People already know how to use it this way having used it in the browser to respond to user initiated events.

4. A lot of people already know JavaScript, even people who do not claim to be programmers. It is arguably the most popular programming language.

5. Using JavaScript on a web server as well as the browser reduces the impedance mismatch between the two programming environments which can communicate data structures via JSON that work the same on both sides of the equation. Duplicate form validation code can be shared between server and client, etc.

If you have Model or transfer object passed to GET method but still have this error, check naming of your variables. Use entity/transfer object names in camelcase. I had BusinessTripDTO object and named it 'trip' for short. It caused this error to occure, even I had all other parts in place. Renaming varaibles to businessTripDTO in Java and Thymeleaf solved this problem for me.

Reason : "Don't know why there is no descendingIterator with ArrayList..."

Since array list doesnot keep the list in the same order as data has been added to list. So, never use Arraylist .

Linked list will keep the data in same order of ADD to list.

So , above in my example, i used ArrayList() in order to make user to twist their mind and make them to workout something from their side.

Instead of this

List<String> list = new ArrayList<String>();

USE:

List<String> list = new LinkedList<String>();

list.add("ravi");

list.add("kant");

list.add("soni");

// Iterate to disply : result will be as ---     ravi kant soni

for (String name : list) {
  ...
}

//Now call this method

Collections.reverse(list);

// iterate and print index wise : result will be as ---     soni kant ravi

for (String name : list) {
  ...
}

As mentioned by Blauhirn after 2.7 pip is preinstalled. If it is not working for you it might need to be added to path.

However if you run Windows 10 you no longer have to open a terminal to install a module. The same goes for opening Python as well.

You can type directly into the search menu pip install mechanize, select command and it will install:

If anything goes wrong however it may close before you can read the error but still it's a useful shortcut.

Use the WebClient class in System.Net:

var json = new WebClient().DownloadString("url");

Keep in mind that WebClient is IDisposable, so you would probably add a using statement to this in production code. This would look like:

using (WebClient wc = new WebClient())
{
   var json = wc.DownloadString("url");
}

I use pyDev with Eclipse really good, set break points, step into code, view values on any objects and variables, try it.

my 5c: In integration and networking the idempotency is very important. Several examples from real-life: Imagine, we deliver data to the target system. Data delivered by a sequence of messages. 1. What would happen if the sequence is mixed in channel? (As network packages always do :) ). If the target system is idempotent, the result will not be different. If the target system depends of the right order in the sequence, we have to implement resequencer on the target site, which would restore the right order. 2. What would happen if there are the message duplicates? If the channel of target system does not acknowledge timely, the source system (or channel itself) usually sends another copy of the message. As a result we can have duplicate message on the target system side. If the target system is idempotent, it takes care of it and result will not be different. If the target system is not idempotent, we have to implement deduplicator on the target system side of the channel.

There is a property in the drawable xml to do it. android:tileMode="repeat"

As a Python programmer, Hungarian Notation falls apart pretty fast. In Python, I don't care if something is a string - I care if it can act like a string (i.e. if it has a ___str___() method which returns a string).

For example, let's say we have foo as an integer, 12

foo = 12

Hungarian notation tells us that we should call that iFoo or something, to denote it's an integer, so that later on, we know what it is. Except in Python, that doesn't work, or rather, it doesn't make sense. In Python, I decide what type I want when I use it. Do I want a string? well if I do something like this:

print "The current value of foo is %s" % foo

Note the %s - string. Foo isn't a string, but the % operator will call foo.___str___() and use the result (assuming it exists). foo is still an integer, but we treat it as a string if we want a string. If we want a float, then we treat it as a float. In dynamically typed languages like Python, Hungarian Notation is pointless, because it doesn't matter what type something is until you use it, and if you need a specific type, then just make sure to cast it to that type (e.g. float(foo)) when you use it.

Note that dynamic languages like PHP don't have this benefit - PHP tries to do 'the right thing' in the background based on an obscure set of rules that almost no one has memorized, which often results in catastrophic messes unexpectedly. In this case, some sort of naming mechanism, like $files_count or $file_name, can be handy.

In my view, Hungarian Notation is like leeches. Maybe in the past they were useful, or at least they seemed useful, but nowadays it's just a lot of extra typing for not a lot of benefit.

If you are having this issue in a Docker container just make sure that node_modules are not added in the .dockerignore file.

I had the same issue sh1 : react scripts not found. For me this was the solution

I think the client looks like a normal asynchronous AJAX request, but you expect it to take a "long time" to come back.

The server then looks like this.

while (!hasNewData())
    usleep(50);

outputNewData();

So, the AJAX request goes to the server, probably including a timestamp of when it was last update so that your hasNewData() knows what data you have already got. The server then sits in a loop sleeping until new data is available. All the while, your AJAX request is still connected, just hanging there waiting for data. Finally, when new data is available, the server gives it to your AJAX request and closes the connection.

honestly; all solutions seem to be a hack to fix a rendering bug ... am i wrong?

i've found <br clear="all" /> to be the easiest, simplest. seeing class="clearfix" everywhere can't stroke the sensibilities of someone who objects to extraneous markeup elements, can it? you're just painting the problem on a different canvas.

i also use the display: hidden solution, which is great and requires no extra class declarations or html markup ... but sometimes you need the elements to overflow the container, for eg. pretty ribbons and sashes

There is a difference in performance.

Simply put HS256 is about 1 order of magnitude faster than RS256 for verification but about 2 orders of magnitude faster than RS256 for issuing (signing).

 640,251  91,464.3 ops/s
  86,123  12,303.3 ops/s (RS256 verify)
   7,046   1,006.5 ops/s (RS256 sign)

Don't get hung up on the actual numbers, just think of them with respect of each other.

            Console.WriteLine($"RS256 is {(n1 / s1.Elapsed.TotalSeconds) / (n2 / s2.Elapsed.TotalSeconds),9:N1}x slower (verify)");
            Console.WriteLine($"RS256 is {(n1 / s1.Elapsed.TotalSeconds) / (n3 / s3.Elapsed.TotalSeconds),9:N1}x slower (issue)");

            // RS256 is about 7.5x slower, but it can still do over 10K ops per sec.
        }
    }
}

You can use this format

It looks like your syntax for unset is invalid, and the lack of reindexing might cause trouble in the future. See: the section on PHP arrays.

The correct syntax is shown above. Also keep in mind array-values for reindexing, so you don't ever index something you previously deleted.

No, how you are doing it is correct.

Angular doesn't provide snazzy UI elements like drag and drop. That's not really Angular's purpose. However, there are a few well known directives that provide drag and drop. Here are two that I've used.

I have had a similar issue in iOS 8, 9 and 10 and the info above couldn't fix it, however I did discover a solution after a day of working on this. Granted it won't work for everyone but in my case my items were stacked in a column and had 0 height when it should have been content height. Switching the css to be row and wrap fixed the issue. This only works if you have a single item and they are stacked but since it took me a day to find this out I thought I should share my fix!

.wrapper {
    flex-direction: column; // <-- Remove this line
    flex-direction: row; // <-- replace it with
    flex-wrap: wrap; // <-- Add wrapping
}

.item {
    width: 100%;
}

static variables are used when only one copy of the variable is required. so if you declare variable inside the method there is no use of such variable it's become local to function only..

example of static is

class myclass
{
    public static int a = 0;
}

Variables declared static are commonly shared across all instances of a class.

Variables declared static are commonly shared across all instances of a class. When you create multiple instances of VariableTest class This variable permanent is shared across all of them. Thus, at any given point of time, there will be only one string value contained in the permanent variable.

Since there is only one copy of the variable available for all instances, the code this.permament will result in compilation errors because it can be recalled that this.variablename refers to the instance variable name. Thus, static variables are to be accessed directly, as indicated in the code.

Here is also a good and simple site to check your php codes and share your code with fiends :

It's very simple steps to push your node js application from local to GitHub.

Steps:

1. First create a new repository on GitHub
2. Open Git CMD installed to your system (Install GitHub Desktop)
3. Clone the repository to your system with the command: git clone repo-url
4. Now copy all your application files to this cloned library if it's not there
5. Get everything ready to commit: git add -A
6. Commit the tracked changes and prepares them to be pushed to a remote repository: git commit -a -m "First Commit"
7. Push the changes in your local repository to GitHub: git push origin master

I was facing the same issue. I tried both $http_my_custom_header and $sent_http_my_custom_header but it did not work for me.

Although solved this issue by using $upstream_http_my_custom_header.

You might be using the enums incorrectly in the switch cases. In comparison with the above example by CoolBeans.. you might be doing the following:

switch(day) {
    case Day.MONDAY:
        // Something..
        break;
    case Day.FRIDAY:
        // Something friday
        break;
}

Make sure that you use the actual enum values instead of EnumType.EnumValue

Eclipse points out this mistake though..

To remove an image from Docker using the image ID:

1. Get the list of all Images

   docker images
   

2. Identify the image ID of the image you want to delete, for example:

   REPOSITORY     TAG     IMAGE ID        CREATED        VIRTUAL SIZE
   kweku360/java  latest  08d3a9b8e166    2 weeks ago         5.733 GB`
   

3. Finally remove the image using the image ID (only the first three digits are required)

   docker rmi 08d
   

I wish I could have read the response by @Ján Lazár.

In addition to all the configurations mentioned in the accepted answer, below setting solved my misery:

For large files the scalability mode must be turned off. Enabling scalability mode will disable reference highlighting.

PS: @Rob Hruska It would be great if this point is added in the accepted answer. Most of the readers do not bother to read the last response.

You cannot do this on multiple fields. You can also look for this.

In other words, doesn't DEFAULT render NOT NULL redundant ?

No, it is not redundant. To extended accepted answer. For column col which is nullable awe can insert NULL even when DEFAULT is defined:

CREATE TABLE t(id INT PRIMARY KEY, col INT DEFAULT 10);

-- we just inserted NULL into column with DEFAULT
INSERT INTO t(id, col) VALUES(1, NULL);

+-----+------+
| ID  | COL  |
+-----+------+
|   1 | null |
+-----+------+

Oracle introduced additional syntax for such scenario to overide explicit NULL with default DEFAULT ON NULL:

CREATE TABLE t2(id INT PRIMARY KEY, col INT DEFAULT ON NULL 10);
-- same as
--CREATE TABLE t2(id INT PRIMARY KEY, col INT DEFAULT ON NULL 10 NOT NULL); 

INSERT INTO t2(id, col) VALUES(1, NULL);

+-----+-----+
| ID  | COL |
+-----+-----+
|  1  |  10 |
+-----+-----+

Here we tried to insert NULL but get default instead.

db<>fiddle demo

ON NULL

If you specify the ON NULL clause, then Oracle Database assigns the DEFAULT column value when a subsequent INSERT statement attempts to assign a value that evaluates to NULL.

When you specify ON NULL, the NOT NULL constraint and NOT DEFERRABLE constraint state are implicitly specified.

Instead of default parameters, why not just construct a dictionary class from the querystring passed .. an implementation that is almost identical to the way asp.net forms work with querystrings.

i.e. Request.QueryString["a"]

This will decouple the leaf class from the factory / boilerplate code.

A dummy answer :-

I think explanation is given in above answer, so i am just gonna tell you where to use STRONG and where to use WEAK :

Use of Weak :- 1. Delegates 2. Outlets 3. Subviews 4. Controls, etc.

Use of Strong :- Remaining everywhere which is not included in WEAK.

I recently wrote a custom directive which can be generic enough to do any validation. It take a validation function from the current scope

module.directive('customValidator', [function () {
        return {
            restrict: 'A',
            require: 'ngModel',
            scope: { validateFunction: '&' },
            link: function (scope, elm, attr, ngModelCtrl) {
                ngModelCtrl.$parsers.push(function (value) {
                    var result = scope.validateFunction({ 'value': value });
                    if (result || result === false) {
                        if (result.then) {
                            result.then(function (data) {           //For promise type result object
                                ngModelCtrl.$setValidity(attr.customValidator, data);
                            }, function (error) {
                                ngModelCtrl.$setValidity(attr.customValidator, false);
                            });
                        }
                        else {
                            ngModelCtrl.$setValidity(attr.customValidator, result);
                            return result ? value : undefined;      //For boolean result return based on boolean value
                        }
                    }
                    return value;
                });
            }
        };
    }]);

To use it you do

<input type="email" name="email2" ng-model="emailReg2" custom-validator='emailMatch' data-validate-function='checkEmailMatch(value)'>
<span ng-show="registerForm.email2.$error.emailMatch">Emails have to match!</span>

In you controller then you can implement the method, that should return true or false

$scope.checkEmailMatch=function(value) {
    return value===$scope.emailReg;
}

The advantage is that you do not have to write custom directive for each custom validation.

A fresh answer for Spring Boot 2.2 is required as server.connection-timeout=5000 is deprecated. Each server behaves differently, so server specific properties are recommended instead.

SpringBoot embeds Tomcat by default, if you haven't reconfigured it with Jetty or something else. Use server specific application properties like server.tomcat.connection-timeout or server.jetty.idle-timeout.

Here's a gotcha that I just discovered - perhaps it might help someone else. If using windows the classes folder must not have encryption enabled! Tomcat doesn't seem to like that. Right click on the classes folder, select "Properties" and then click the "Advanced..." button. Make sure the "Encrypt contents to secure data" checkbox is cleared. Restart Tomcat.

It worked for me so here's hoping it helps someone else, too.

On Windows 7, go to C:\Users\%User_Name%\AppData\Roaming\Subversion and remove the auth directory. Just be aware if you are connected to more than 1 SVN server that this will remove the authentication for all of the SVN servers you have configured. If you want to reset just a single server:

Inside the auth directory you should see a folder called svn.simple. Open each of those files with a text editor to determine which one to remove and then remove just that single file.

Reinstalling RVM worked for me, but I had to reinstall all of my gems afterward:

Include input type="file" element on your HTML page and on the click event of your button trigger the click event of input type file element using trigger function of jQuery

The code will look like:

<input type="file" id="imgupload" style="display:none"/> 
<button id="OpenImgUpload">Image Upload</button>

And on the button's click event write the jQuery code like :

$('#OpenImgUpload').click(function(){ $('#imgupload').trigger('click'); });

This will open File Upload Dialog box on your button click event..

make sure you are not including the jquery code between the

< script > < /script >

If so remove that and code will work fine, It worked in my case.

I think you could do it using a specs file.

Under MinGW you could run
gcc -dumpspecs > specs

Where it says

*cpp:
%{posix:-D_POSIX_SOURCE} %{mthreads:-D_MT}

You change it to

*cpp:
%{posix:-D_POSIX_SOURCE} %{mthreads:-D_MT} -std=c++11

And then place it in
/mingw/lib/gcc/mingw32/<version>/specs

I'm sure you could do the same without a MinGW build. Not sure where to place the specs file though.

The folder is probably either /gcc/lib/ or /gcc/.

let arr = [11,22,11,22];

let hasDuplicate = arr.some((val, i) => arr.indexOf(val) !== i);
// hasDuplicate = true

True -> array has duplicates

False -> uniqe array

This is simple and sort. Use hsla css function like below

.transparent {
   background-color: hsla(0,0%,4%,.4);
}

I found the reason why there is always a white boder of the background image, if I put the image in a 'div' element inside 'body'. But the image can be full screen, if I put it as background image of 'body'.

Because the default 'margin' of 'body' is not zero. After add this css, the background image can be full screen even I put it in 'div'.

body {
    margin: 0px;
}

In addition to the answer
1. Open POSTMAN
2. Click on "import" tab on the upper left side.
3. Select the Raw Text option and paste your cURL command.
4. Hit import and you will have the command in your Postman builder!
5. If -u admin:admin are not imported, just go to the Authorization 
   tab, select Basic Auth -> enter the user name eg admin and password eg admin.
This will automatically generate Authorization header based on Base64 encoder

You could try using the third-party tool called NirCmd. It is a genuine, free command line utility. If or when you have it, use this code in a batch file:

title Open Word
nircmd win hide title "Open Word"
start "C:\Program" "Files" "(x86)\Microsoft" "Office\Office12\WINWORD.exe
nircmd wait 20
nircmd win min foreground
exit

This program, in order, changes its title, hides itself according to its title, starts Word, waits 20 milliseconds as a buffer for Word to settle, minimizes Word by assuming it is now the top window, and then exits itself. This program should work as intended as long as their are no key presses or clicks in that ~50 millisecond time window, which shouldn't be hard.

As for installing nircmd on your computer, use this link, and click "Download NirCmd" at the bottom of the page. Save the .zip folder to a normal directory (like "My Documents"), extract it, and copy "nircmd.exe" to %systemroot%\system32, and there you go. Now you have nircmd included with your command line utilities.

I have successfully styled my Bootstrap navbar using the following CSS. Also you didn't define any font in your CSS so that's why the font isn't changing. The site for which this CSS is used can be found here.

.navbar-default .navbar-nav > li > a:hover, .navbar-default .navbar-nav > li > a:focus {
    color: #000; /*Sets the text hover color on navbar*/
}

.navbar-default .navbar-nav > .active > a, .navbar-default .navbar-nav > .active >
        a:hover, .navbar-default .navbar-nav > .active > a:focus {
    color: white; /*BACKGROUND color for active*/
    background-color: #030033;
}

.navbar-default {
    background-color: #0f006f;
    border-color: #030033;
}

.dropdown-menu > li > a:hover,
.dropdown-menu > li > a:focus {
    color: #262626;
    text-decoration: none;
    background-color: #66CCFF; /*change color of links in drop down here*/
}

.nav > li > a:hover,
.nav > li > a:focus {
    text-decoration: none;
    background-color: silver; /*Change rollover cell color here*/
}

.navbar-default .navbar-nav > li > a {
    color: white; /*Change active text color here*/
}

After a recent update on my Ubuntu 16.04 system I have also started getting this error when trying to run convert on .ps files to convert them into pdfs.

This fix worked for me:

In a terminal run:

sudo gedit /etc/ImageMagick-6/policy.xml

This should open the policy.xml file in the gedit text editor. If it doesn't, your image magick might be installed in a different place. Then change

rights="none" 

to

rights="read | write" 

for PDF, EPS and PS lines near the bottom of the file. Save and exit, and image magick should then work again.

You can do this in a couple of ways.

One, is to build up the query yourself and execute it.

SET @sql = 'SELECT ' + @columnName + ' FROM yourTable'
sp_executesql @sql

If you opt for that method, be very certain to santise your input. Even if you know your application will only give 'real' column names, what if some-one finds a crack in your security and is able to execute the SP directly? Then they can execute just about anything they like. With dynamic SQL, always, always, validate the parameters.

Alternatively, you can write a CASE statement...

SELECT
  CASE @columnName
    WHEN 'Col1' THEN Col1
    WHEN 'Col2' THEN Col2
                ELSE NULL
  END as selectedColumn
FROM
  yourTable

This is a bit more long winded, but a whole lot more secure.

It should be possible changing setting the JAVA_HOME environment variable differently for specific applications.

When starting from the command line or from a batch script you can use set JAVA_HOME=C:\...\j2dskXXX to change the JAVA_HOME environment.

It is possible that you also need to change the PATH environment variable to use the correct java binary. To do this you can use set PATH=%JAVA_HOME%\bin;%PATH%.

There's no such thing as a “good hash function” for universal hashes (ed. yes, I know there's such a thing as “universal hashing” but that's not what I meant). Depending on the context different criteria determine the quality of a hash. Two people already mentioned SHA. This is a cryptographic hash and it isn't at all good for hash tables which you probably mean.

Hash tables have very different requirements. But still, finding a good hash function universally is hard because different data types expose different information that can be hashed. As a rule of thumb it is good to consider all information a type holds equally. This is not always easy or even possible. For reasons of statistics (and hence collision), it is also important to generate a good spread over the problem space, i.e. all possible objects. This means that when hashing numbers between 100 and 1050 it's no good to let the most significant digit play a big part in the hash because for ~ 90% of the objects, this digit will be 0. It's far more important to let the last three digits determine the hash.

Similarly, when hashing strings it's important to consider all characters – except when it's known in advance that the first three characters of all strings will be the same; considering these then is a waste.

This is actually one of the cases where I advise to read what Knuth has to say in The Art of Computer Programming, vol. 3. Another good read is Julienne Walker's The Art of Hashing.

I was searching about how stack works in terms of function and i found this blog its awesome and its explain concept of stack from scratch and how stack store value in stack.

Now on your answer . I will explain with python but you will get good idea how stack works in any language.

Its a program :

def hello(x):
    if x==1:
        return "op"
    else:
        u=1
        e=12
        s=hello(x-1)
        e+=1
        print(s)
        print(x)
        u+=1
    return e

hello(3)

But its explain with python language so if you want you can take a look.

You are asking two separate questions here:

What's the maximum length of an HTTP GET request?

As already mentioned, HTTP itself doesn't impose any hard-coded limit on request length; but browsers have limits ranging on the 2 KB - 8 KB (255 bytes if we count very old browsers).

Is there a response error defined that the server can/should return if it receives a GET request exceeds this length?

That's the one nobody has answered.

HTTP 1.1 defines status code 414 Request-URI Too Long for the cases where a server-defined limit is reached. You can see further details on RFC 2616.

For the case of client-defined limits, there isn't any sense on the server returning something, because the server won't receive the request at all.

1) Start by opening up git-bash.exe in Administrator mode. (Right click the file and select "Run as Administrator", or change settings in Properties → Compatibility → Run this program as administrator.)

2) Run cd ~. It will take you to C:/Users/<Your-Username>.

3) Run vi .bashrc. This will open you up into the editor. Hit INSERT and then start entering the following info:

alias ll="ls -la" # this changes the default ll on git bash to see hidden files.
cd "C:\directory\to\your\work\path\"
ll # this shows your your directory before you even type anything.

It took me a while, but I discovered that including the following was what made it possible to change the navbar color:

.navbar{ 
    background-image: none;
}

In Java 1.4 and up:

String input = "...";
Matcher matcher = Pattern.compile("[^0-9]+([0-9]+)[^0-9]+").matcher(input);
if (matcher.find()) {
    String someNumberStr = matcher.group(1);
    // if you need this to be an int:
    int someNumberInt = Integer.parseInt(someNumberStr);
}

Steps to change the default date format of ng-model

For different date formats check the jqueryui datepicker date format values here for example I have used dd/mm/yy

Create angularjs directive

angular.module('app', ['ui.bootstrap']).directive('dt', function () {
return {
    restrict: 'EAC',
    require: 'ngModel',
    link: function (scope, element, attr, ngModel) {
        ngModel.$parsers.push(function (viewValue) {
           return dateFilter(viewValue, 'dd/mm/yy');
        });
    }
 }
});

Write dateFilter function

function dateFilter(val,format) {
    return $.datepicker.formatDate(format,val);
}

In html page write the ng-modal attribute

<input type="text" class="form-control" date-type="string"  uib-datepicker-popup="{{format}}" ng-model="src.pTO_DATE" is-open="popup2.opened" datepicker-options="dateOptions" ng-required="true" close-text="Close" show-button-bar="false" show-weeks="false" dt />

mysql_fetch_assoc returns an array so you can not echo an array, need to print_r() otherwise particular string $money['money'].

Here is a Swift 2.3. (Xcode 8.0) solution. I have created a subclass of UITableView.

class MYCustomTableView: UITableView
{   
    override func drawRect(rect: CGRect) {
        super.drawRect(rect)
        contentInset    = UIEdgeInsetsZero
    }
}

The content Inset should always be Zero (by default). I am setting it Zero manually. You can also add a check method which makes the check and if it is anything other than what you want it to be just get the correct rect. The change will reflect only when the tableview is drawn (which does not happen often).

Don't forget to update the TableView in your IB (in the TableViewController or just TableView inside your ViewController).

<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">

   <appender name="fileAppender" class="org.apache.log4j.RollingFileAppender">
      <param name="Threshold" value="INFO" />
      <param name="File" value="sample.log"/>
      <layout class="org.apache.log4j.PatternLayout">

      </layout>

  </root> 

</log4j:configuration>

Log4j can be a bit confusing. So lets try to understand what is going on in this file: In log4j you have two basic constructs appenders and loggers.

Appenders define how and where things are appended. Will it be logged to a file, to the console, to a database, etc.? In this case you are specifying that log statements directed to fileAppender will be put in the file sample.log using the pattern specified in the layout tags. You could just as easily create a appender for the console or the database. Where the console appender would specify things like the layout on the screen and the database appender would have connection details and table names.

Loggers respond to logging events as they bubble up. If an event catches the interest of a specific logger it will invoke its attached appenders. In the example below you have only one logger the root logger - which responds to all logging events by default. In addition to the root logger you can specify more specific loggers that respond to events from specific packages. These loggers can have their own appenders specified using the appender-ref tags or will otherwise inherit the appenders from the root logger. Using more specific loggers allows you to fine tune the logging level on specific packages or to direct certain packages to other appenders.

So what this file is saying is:

1. Create a fileAppender that logs to file sample.log
2. Attach that appender to the root logger.
3. The root logger will respond to any events at least as detailed as 'debug' level
4. The appender is configured to only log events that are at least as detailed as 'info'

The net out is that if you have a logger.debug("blah blah") in your code it will get ignored. A logger.info("Blah blah"); will output to sample.log.

The snippet below could be added to the file above with the log4j tags. This logger would inherit the appenders from <root> but would limit the all logging events from the package org.springframework to those logged at level info or above.

  <!-- Example Package level Logger -->
    <logger name="org.springframework">
        <level value="info"/>
    </logger>   

Just use the Date property:

var today = DateTime.Today;

var q = db.Games.Where(t => t.StartDate.Date >= today)
                .OrderBy(t => t.StartDate);

Note that I've explicitly evaluated DateTime.Today once so that the query is consistent - otherwise each time the query is executed, and even within the execution, Today could change, so you'd get inconsistent results. For example, suppose you had data of:

Entry 1: March 8th, 8am
Entry 2: March 10th, 10pm
Entry 3: March 8th, 5am
Entry 4: March 9th, 8pm

Surely either both entries 1 and 3 should be in the results, or neither of them should... but if you evaluate DateTime.Today and it changes to March 9th after it's performed the first two checks, you could end up with entries 1, 2, 4.

Of course, using DateTime.Today assumes you're interested in the date in the local time zone. That may not be appropriate, and you should make absolutely sure you know what you mean. You may want to use DateTime.UtcNow.Date instead, for example. Unfortunately, DateTime is a slippery beast...

EDIT: You may also want to get rid of the calls to DateTime static properties altogether - they make the code hard to unit test. In Noda Time we have an interface specifically for this purpose (IClock) which we'd expect to be injected appropriately. There's a "system time" implementation for production and a "stub" implementation for testing, or you can implement it yourself.

You can use the same idea without using Noda Time, of course. To unit test this particular piece of code you may want to pass the date in, but you'll be getting it from somewhere - and injecting a clock means you can test all the code.

If it is inline, the browser should attempt to render it within the browser window. If it cannot, it will resort to an external program, prompting the user.

With attachment, it will immediately go to the user, and not try to load it in the browser, whether it can or not.

You can use esentutl to copy (mainly big) files with a progress bar:

esentutl /y "my.file" /d "another.file" /o

the progress bar looks like this:

for angular2 RC5 this worked for me...

first install moment via npm

npm install moment --save

Then import moment in the component that you want to use it

import * as moment from 'moment';

lastly configure moment in systemjs.config.js "map" and "packages"

// map tells the System loader where to look for things
  var map = {
  ....
  'moment':                     'node_modules/moment'
  };
  // packages tells the System loader how to load when no filename and/or no extension
  var packages = {
    ...
    'moment':                       { main:'moment', defaultExtension: 'js'}
  };

To remove the scrollbar add the following CSS:

select[multiple] {
    overflow-y: auto;
}

Here's a snippet:

select[multiple] {_x000D_
  overflow-y: auto;_x000D_
}

<select>_x000D_
  <option value="1">One</option>_x000D_
  <option value="2">Two</option>_x000D_
  <option value="3">Three</option>_x000D_
</select>_x000D_
_x000D_
<select multiple size="3">_x000D_
  <option value="1">One</option>_x000D_
  <option value="2">Two</option>_x000D_
  <option value="3">Three</option>_x000D_
</select>

This worked for me

let exampleArray = [1, 2, 3, 4, 5];
let exampleToString = exampleArray.toString(); //convert to toString
let query = `Select * from table_name where column_name in (${exampleToString})`; //Execute the query to get response

I have got the same problem, then after an hour of effort I got to know that the array should not be directly accessed in the query. So I then found that the data should be sent in the paranthesis it self, then again I have converted that array to string using toString method in js. So I have worked by executing the above query and got my expected result

Try below

Something..TrimEnd(",".ToCharArray());

Here is how you would do this with a nested list comprehension:

[[float(y) for y in x] for x in l]

This would give you a list of lists, similar to what you started with except with floats instead of strings. If you want one flat list then you would use [float(y) for x in l for y in x].

It looks much like a list of Django ORM model instances.

Why not sort them on query like this:

ut = Tag.objects.order_by('-count')

When u call finish onDestroy() of that activity will be called and it will go back to previous activity in the activity stack... So.. for exit do not call finish();

Blow codes could help you...

Fetch Numbers:

return string.Concat(input.Where(char.IsNumber));

Fetch Letters:

return string.Concat(input.Where(char.IsLetter));

For Swift 3 & Swift 4 :

Since UIAlertView is deprecated, there is the good way for display Alert on Swift 3

let alertController = UIAlertController(title: NSLocalizedString("No network connection",comment:""), message: NSLocalizedString("connected to the internet to use this app.",comment:""), preferredStyle: .alert)
let defaultAction = UIAlertAction(title:     NSLocalizedString("Ok", comment: ""), style: .default, handler: { (pAlert) in
                //Do whatever you want here
        })
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)

Deprecated :

This is the swift version inspired by the checked response :

Display AlertView :

   let alert = UIAlertView(title: "No network connection", 
                           message: "You must be connected to the internet to use this app.", delegate: nil, cancelButtonTitle: "Ok")
    alert.delegate = self
    alert.show()

Add the delegate to your view controller :

class AgendaViewController: UIViewController, UIAlertViewDelegate

When user click on button, this code will be executed :

func alertView(alertView: UIAlertView, clickedButtonAtIndex buttonIndex: Int) {


}

The simplest way is using pip command:

pip list | grep Keras

var reader = cmd.ExecuteReader();

var columns = new List<string>();

for(int i=0;i<reader.FieldCount;i++)
{
   columns.Add(reader.GetName(i));
}

or

var columns = Enumerable.Range(0, reader.FieldCount).Select(reader.GetName).ToList();

The solution above won't work if the original string has no spaces.

Try this:

var title = "This is your title";
var shortText = jQuery.trim(title).substring(0, 10)
                          .trim(this) + "...";

you can use reflect.TypeOf.

• basic type(e.g.: int, string): it will return its name (e.g.: int, string)
• struct: it will return something in the format <package name>.<struct name> (e.g.: main.test)

Here is a website to create a Parcelable Class from your created class:

Well now will be different after angular 5:

{{ number | currency :'GBP':'symbol':'1.2-2' }}

According to Microsoft documentation, should NEVER use async void

Do not do this: The following example uses async void which makes the HTTP request complete when the first await is reached:

• Which is ALWAYS a bad practice in ASP.NET Core apps.

• Accesses the HttpResponse after the HTTP request is complete.

• Crashes the process.

You should use datetime object, not str.

>>> from datetime import datetime
>>> cr_date = datetime(2013, 10, 31, 18, 23, 29, 227)
>>> cr_date.strftime('%m/%d/%Y')
'10/31/2013'

To get the datetime object from the string, use datetime.datetime.strptime:

>>> datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f')
datetime.datetime(2013, 10, 31, 18, 23, 29, 227)
>>> datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f').strftime('%m/%d/%Y')
'10/31/2013'

A working example to implement the accepted answer by adding a "Boolean" column to an existing table in an oracle database (using number type):

ALTER TABLE my_table_name ADD (
my_new_boolean_column number(1) DEFAULT 0 NOT NULL
CONSTRAINT my_new_boolean_column CHECK (my_new_boolean_column in (1,0))
);

This creates a new column in my_table_name called my_new_boolean_column with default values of 0. The column will not accept NULL values and restricts the accepted values to either 0 or 1.

Try using Sublime Package Control to install your packages.

Also take a look at these tips

strtok is an overlooked function for this sort of thing. It is meant to be quite fast.

$s = '233718_This_is_a_string';
$firstPart = strtok( $s, '_' );
$allTheRest = strtok( '' ); 

Empty string like this will force the rest of the string to be returned.

NB if there was nothing at all after the '_' you would get a FALSE value for $allTheRest which, as stated in the documentation, must be tested with ===, to distinguish from other falsy values.

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...

public static void setSelectedValue(JComboBox comboBox, int value)
    {
        ComboItem item;
        for (int i = 0; i < comboBox.getItemCount(); i++)
        {
            item = (ComboItem)comboBox.getItemAt(i);
            if (item.getValue().equalsIgnoreCase(value))
            {
                comboBox.setSelectedIndex(i);
                break;
            }
        }
    }

Hope this help :)

This is Simple and best calculation for me and may be for you.

       try {
            /// String CurrDate=  "10/6/2013";
            /// String PrvvDate=  "10/7/2013";
            Date date1 = null;
            Date date2 = null;
            SimpleDateFormat df = new SimpleDateFormat("M/dd/yyyy");
            date1 = df.parse(CurrDate);
            date2 = df.parse(PrvvDate);
            long diff = Math.abs(date1.getTime() - date2.getTime());
            long diffDays = diff / (24 * 60 * 60 * 1000);


            System.out.println(diffDays);

        } catch (Exception e1) {
            System.out.println("exception " + e1);
        }

The best solution seem to be to create a file list and then archive files because you can use other sources and do something else with the list.

For example this allows using the list to calculate size of the files being archived:

#!/bin/sh

backupFileName="backup-big-$(date +"%Y%m%d-%H%M")"
backupRoot="/var/www"
backupOutPath=""

archivePath=$backupOutPath$backupFileName.tar.gz
listOfFilesPath=$backupOutPath$backupFileName.filelist

#
# Make a list of files/directories to archive
#
echo "" > $listOfFilesPath
echo "${backupRoot}/uploads" >> $listOfFilesPath
echo "${backupRoot}/extra/user/data" >> $listOfFilesPath
find "${backupRoot}/drupal_root/sites/" -name "files" -type d >> $listOfFilesPath

#
# Size calculation
#
sizeForProgress=`
cat $listOfFilesPath | while read nextFile;do
    if [ ! -z "$nextFile" ]; then
        du -sb "$nextFile"
    fi
done | awk '{size+=$1} END {print size}'
`

#
# Archive with progress
#
## simple with dump of all files currently archived
#tar -czvf $archivePath -T $listOfFilesPath
## progress bar
sizeForShow=$(($sizeForProgress/1024/1024))
echo -e "\nRunning backup [source files are $sizeForShow MiB]\n"
tar -cPp -T $listOfFilesPath | pv -s $sizeForProgress | gzip > $archivePath

Make second argument of Response false as shown below.

Response.Redirect(url,false);

I use a relative path solution,

./../../../../../images/img.png

every ../ will take you one folder up towards the root. Hope this helps..

just use

git config --global credential.helper store

and do the git pull, it will ask for username and password, from now on it will not provide any prompt for username and password it will store the details

If someone referring how to do the same feature (reading OTP using received SMS) on Xamarin Android like me :

1. Add this code to your AndroidManifest.xml file :

   <receiver android:name=".listener.BroadcastReveiverOTP">
   <intent-filter>
       <action android:name="android.provider.Telephony.SMS_RECEIVED" />
   </intent-filter>
   </receiver>
   <uses-permission android:name="android.permission.RECEIVE_SMS" />
   <uses-permission android:name="android.permission.BROADCAST_SMS" />
   <uses-permission android:name="android.permission.READ_SMS" />
   

2. Then create your BroadcastReveiver class in your Android Project.

   [BroadcastReceiver(Enabled = true)] [IntentFilter(new[] { "android.provider.Telephony.SMS_RECEIVED" }, Priority = (int)IntentFilterPriority.HighPriority)] 
   public class BroadcastReveiverOTP : BroadcastReceiver {
           public static readonly string INTENT_ACTION = "android.provider.Telephony.SMS_RECEIVED";
   
           protected string message, address = string.Empty;
   
           public override void OnReceive(Context context, Intent intent)
           {
               if (intent.HasExtra("pdus"))
               {
                   var smsArray = (Java.Lang.Object[])intent.Extras.Get("pdus");
                   foreach (var item in smsArray)
                   {
                       var sms = SmsMessage.CreateFromPdu((byte[])item);
                       address = sms.OriginatingAddress;
                       if (address.Equals("NotifyDEMO"))
                       {
                           message = sms.MessageBody;
                           string[] pin = message.Split(' ');
                           if (!string.IsNullOrWhiteSpace(pin[0]))
                           { 
                                   // NOTE : Here I'm passing received OTP to Portable Project using MessagingCenter. So I can display the OTP in the relevant entry field.
                                   MessagingCenter.Send<object, string>(this,MessengerKeys.OnBroadcastReceived, pin[0]);
                           }
                           }
                   }
               }
           }
   }
   

3. Register this BroadcastReceiver class in your MainActivity class on Android Project:

   public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity {
   
           // Initialize your class
           private BroadcastReveiverOTP _receiver = new BroadcastReveiverOTP ();
   
           protected override void OnCreate(Bundle bundle) { 
                   base.OnCreate(bundle);
   
                   global::Xamarin.Forms.Forms.Init(this, bundle);
                   LoadApplication(new App());
   
                   // Register your receiver :  RegisterReceiver(_receiver, new IntentFilter("android.provider.Telephony.SMS_RECEIVED"));
   
           }
   }
   

If you want to change the size of plot the use arg figsize

df.groupby(['NFF', 'ABUSE']).size().unstack()
      .plot(kind='bar', stacked=True, figsize=(15, 5))

Using more_itertools.with_iter, it is possible to open, read, close and assign an equivalent output in one line (excluding the import statement):

import more_itertools as mit


output = "".join(line for line in mit.with_iter(open("pagehead.section.htm", "r")))

Although possible, I would look for another approach other than assigning the contents of a file to a variable, i.e. lazy iteration - this can be done using a traditional with block or in the example above by removing join() and iterating output.

This is a more up to date answer:

import s3fs

s3 = s3fs.S3FileSystem(anon=False)

# Use 'w' for py3, 'wb' for py2
with s3.open('<bucket-name>/<filename>.csv','w') as f:
    df.to_csv(f)

The problem with StringIO is that it will eat away at your memory. With this method, you are streaming the file to s3, rather than converting it to string, then writing it into s3. Holding the pandas dataframe and its string copy in memory seems very inefficient.

If you are working in an ec2 instant, you can give it an IAM role to enable writing it to s3, thus you dont need to pass in credentials directly. However, you can also connect to a bucket by passing credentials to the S3FileSystem() function. See documention:https://s3fs.readthedocs.io/en/latest/

there are lots of compression methods that work recursively command line and its good to know who the end audience is.

i.e. if it is to be sent to someone running windows then zip would probably be best:

zip -r file.zip folder_to_zip

unzip filenname.zip

for other linux users or your self tar is great

tar -cvzf filename.tar.gz folder

tar -cvjf filename.tar.bz2 folder  # even more compression

#change the -c to -x to above to extract

One must be careful with tar and how things are tarred up/extracted, for example if I run

cd ~
tar -cvzf passwd.tar.gz /etc/passwd
tar: Removing leading `/' from member names
/etc/passwd


pwd

/home/myusername

tar -xvzf passwd.tar.gz

this will create /home/myusername/etc/passwd

unsure if all versions of tar do this:

 Removing leading `/' from member names

If you can not use *ngif, [class.hide] works in angular 7. example:

<mat-select (selectionChange)="changeFilter($event.value)" multiple [(ngModel)]="selected">
          <mat-option *ngFor="let filter of gridOptions.columnDefs"
                      [class.hide]="filter.headerName=='Action'"  [value]="filter.field">{{filter.headerName}}</mat-option>
        </mat-select>

In general, to make a raw string out of a string variable, I use this:

string = "C:\\Windows\Users\alexb"

raw_string = r"{}".format(string)

output:

'C:\\\\Windows\\Users\\alexb'

After getting the help from @Blender, @ekhumoro and @Dan, I understand the Linux and Python more than before. Thank you. I got the an idea by @ekhumoro, it is I didn't install PyQt5 correctly. So I delete PyQt5 folder and download again. And redo everything from very start.

After redoing, I got the error as my last update at my question. So, when I search at stack, I got the following solution from here

sudo ln -s /usr/include/python2.7 /usr/local/include/python2.7

And then, I did "sudo make" and "sudo make install" step by step. After "sudo make install", I got the following error. But I ignored it and I created a simple design with qt designer. And I converted it into python file by pyuic5. Everything are going well.

install -m 755 -p /home/thura/PyQt/pyuic5 /usr/bin/
strip /usr/bin/pyuic5
strip:/usr/bin/pyuic5: File format not recognized
make: [install_pyuic5] Error 1 (ignored)

Here is a neat and clean way to install Python2 & Python3 on windows.

https://datascience.com.co/how-to-install-python-2-7-and-3-6-in-windows-10-add-python-path-281e7eae62a

My case: I had to install Apache cassandra. I already had Python3 installed in my D: drive. With loads of development work under process i didn't wanted to mess my Python3 installation. And, i needed Python2 only for Apache cassandra.

So i took following steps:

1. Downloaded & Installed Python2.
2. Added Python2 entries to classpath (C:\Python27;C:\Python27\Scripts)
3. Modified python.exe to python2.exe (as shown in image below)

4. Now i am able to run both. For Python 2(python2 --version) & Python 3 (python --version).

So, my Python3 installation remained intact.

My case is same as @7guyo mentioned. I'm using lazyloading and was unconsiously doing this:

import { component1Route } from './path/component1.route';

export const entityState: Routes = [
{
   path: 'home',
   children: component1Route
}]

Instead of:

@NgModule({
imports: [
   RouterModule.forChild([
   {
     path: '',
     loadChildren: () => import('./component1/component1.module').then(m => m.ComponentOneModule)
  },
  {
    path: '',
    loadChildren: () => import('./component2/component2.module').then(m => m.ComponentTwoModule)
  }])
  ]})

  export class MainModule {}

This might help someone in the future, you can style the label for the input as you like and put anything you want inside it and hide the input with display none.

It works perfectly on cordova with iOS

<link href="https://cdnjs.cloudflare.com/ajax/libs/ratchet/2.0.2/css/ratchet.css" rel="stylesheet"/>_x000D_
<label for="imageUpload" class="btn btn-primary btn-block btn-outlined">Seleccionar imagenes</label>_x000D_
<input type="file" id="imageUpload" accept="image/*" style="display: none">

Unfortunately, no. This feature is not available for facebook albums.

You have to reference System.Configuration via explorer (not only append using System.Configuration). Then you can write:

string xmlDataDirectory = 
    System.Configuration.ConfigurationManager.AppSettings.Get("xmlDataDirectory");

Tested with VS2010 (thanks to www.developpez.net). Hope this helps.

Just spent a hour or so doing this and with the help of Brad's advice and a few additional changes it all worked.

I've done this using the following: 10.7.3, Xcode 4.3.2, iOS 5.1 btw.

1) Right click on your myapp.xcodeproj and select package contents

2) open project.pbxproj with a text editor (don't recommend textedit as it may screw up the formatting)

3) Scroll all the way down until you find /* Begin XCBuildConfiguration section */

4) Notice that you have a debug and release sections

5) In the release section take a look at CODE_SIGN_IDENTITY & "CODE_SIGN_IDENTITY[sdk=iphoneos*]" it should look something like this:

CODE_SIGN_IDENTITY = "iPhone Distribution: MyCompany LLC";
"CODE_SIGN_IDENTITY[sdk=iphoneos*]" = "iPhone Distribution: MyCompany LLC";

6) Take a look at PROVISIONING_PROFILE and "PROVISIONING_PROFILE[sdk=iphoneos*]" they should look like this:

PROVISIONING_PROFILE = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";
"PROVISIONING_PROFILE[sdk=iphoneos*]" = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";

This should match your provisioning profile in Xcode. To see if they match open Xcode > Window > Organizer > Devices > Provisioning Profiles > Right click on the profile > Reveal in Finder > The filename of the .mobileprovision is your profile id.

7) Scroll down in the project.pbxproj and find a second instance of the release section. The second instance of the release section should end with a comment saying /* End XCBuildConfiguration section */

8) make sure that the second section matches the first section so that CODE_SIGN_IDENTITY, "CODE_SIGN_IDENTITY[sdk=iphoneos*], and PROVISIONING_PROFILE are all filled in.

As for your last question, here's the problem illustrated with a simple example:

Let's say that your list contains 5 elements: list = [1, 2, 3, 4, 5] and your list of items to remove (i.e. the indices) is indices_to_remove = [0, 2, 4]. In the first iteration of the loop you remove the item at index 0, so your list becomes list = [2, 3, 4, 5]. In the second iteration, you remove the item at index 2, so your list becomes list = [2, 3, 5] (as you can see, this removes the wrong element). Finally, in the third iteration, you try to remove the element at index 4, but the list only contains three elements, so you get an out of bounds exception.

Now that you see what the problem is, hopefully you will be able to come up with a solution. Good luck!

I am not sure you can dynamically change profiles.

Why not just have an internal properties file with the spring.config.location property set to your desired outside location, and the properties file at that location (outside the jar) have the spring.profiles.active property set?

Better yet, have an internal properties file, specific to dev profile (has spring.profiles.active=dev) and leave it like that, and when you want to deploy in production, specify a new location for your properties file, which has spring.profiles.active=prod:

java -jar myjar.jar --spring.config.location=D:\wherever\application.properties

 public static String getcurrentDateAndTime(){

        Date c = Calendar.getInstance().getTime();
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy/MM/dd");
        String formattedDate = simpleDateFormat.format(c);
        return formattedDate;
    }

// String currentdate=  getcurrentDateAndTime();

The solution given by xenoterracide to use

logging.level.org.apache.http=DEBUG

is good but the problem is that by default Apache HttpComponents is not used.

To use Apache HttpComponents add to your pom.xml

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpasyncclient</artifactId>
</dependency>

and configure RestTemplate with :

RestTemplate restTemplate = new RestTemplate();
restTemplate.setRequestFactory(new HttpComponentsAsyncClientHttpRequestFactory());

Debug Diagnostics Tool (DebugDiag) can be a lifesaver. It creates and analyze IIS crash dumps. I figured out my crash in minutes once I saw the call stack. https://support.microsoft.com/en-us/kb/919789

The characters '<', and '>', are to indicate a place-holder, you should remove them to read:

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME

I had docker up to date, docker said it was running, and the diagnosis was good. I needed to unset some legacy environment variable (thanks https://docs.docker.com/docker-for-mac/troubleshoot/#workarounds-for-common-problems )

unset DOCKER_HOST
unset DOCKER_CERT_PATH
unset DOCKER_TLS_VERIFY

I couldn't get my PYTHONPATH to work properly. I realized adding export fixed the issue:

(did work)

export PYTHONPATH=$PYTHONPATH:~/test/site-packages

vs.

(did not work)

PYTHONPATH=$PYTHONPATH:~/test/site-packages

'L' means wchar_t, which, as opposed to a normal character, requires 16-bits of storage rather than 8-bits. Here's an example:

"A"    = 41
"ABC"  = 41 42 43
L"A"   = 00 41
L"ABC" = 00 41 00 42 00 43

A wchar_t is twice big as a simple char. In daily use you don't need to use wchar_t, but if you are using windows.h you are going to need it.

The endpoint should also have the namespace:

 <endpoint address="uri" binding="wsHttpBinding" contract="Namespace.Interface" />

set the port with app.run(port=80,debug=True) you should set debug to true when on dev

private void Form1_Load(object sender, EventArgs e)
    {
        DataTable StudentDataTable = new DataTable("Student");

        //perform this on the Load Event of the form
        private void AddColumns() 
        {
            StudentDataTable.Columns.Add("First_Int_Column", typeof(int));
            StudentDataTable.Columns.Add("Second_String_Column", typeof(String));

            this.dataGridViewDisplay.DataSource = StudentDataTable;
        }
    }

    //Save_Button_Event to save the form field to the table which is then bind to the TableGridView
    private void SaveForm()
        {
            StudentDataTable.Rows.Add(new object[] { textBoxFirst.Text, textBoxSecond.Text});

            dataGridViewDisplay.DataSource = StudentDataTable;
        }

In my case just work when i add "project" to compile:

repositories {
    mavenCentral()
    flatDir {
        dirs 'libs'
    }
}


dependencies {
   compile project('com.x.x:x:1.0.0')
}

In this case you can use display:inline or inline-block.

Example:

img.likeordisklike {display:inline;vertical-align:middle;  }_x000D_
h4.liketext { color:#F00; display:inline;vertical-align:top;padding-left:10px; }

<img class='likeordislike' src='design/like.png'/><h4 class='liketext'>$likes</h4>_x000D_
<img class='likeordislike' src='design/dislike.png'/><h4 class='liketext'>$dislikes</h4>

Don't use float:left because again need to write one more clear line and its old method also..

Sum list of numbers:

sum(list_of_nums)

Calculating half of n and n - 1 (if I have the pattern correct), using a list comprehension:

[(x + (x - 1)) / 2 for x in list_of_nums]

Sum adjacent elements, e.g. ((1 + 2) / 2) + ((2 + 3) / 2) + ... using reduce and lambdas

reduce(lambda x, y: (x + y) / 2, list_of_nums)

You are passing the address of the first element of the array

Seems like a connection issue. You can use the Data link properties to find if the connection is fine. Do the following:

1. Create a blank notepad and rename it to "X.UDL"
2. Double click to open it
3. Under connections tab choose the server name/enter the name use the correct credentials and DB
4. Click OK to save it.

Now open the file in Notepad and compare the connection string properties.

Use a BindingList and set the DataPropertyName-Property of the column.

Try the following:

...
private void BindGrid()
{
    gvFilesOnServer.AutoGenerateColumns = false;

    //create the column programatically
    DataGridViewCell cell = new DataGridViewTextBoxCell();
    DataGridViewTextBoxColumn colFileName = new DataGridViewTextBoxColumn()
    {
        CellTemplate = cell, 
        Name = "Value",
        HeaderText = "File Name",
        DataPropertyName = "Value" // Tell the column which property of FileName it should use
     };

    gvFilesOnServer.Columns.Add(colFileName);

    var filelist = GetFileListOnWebServer().ToList();
    var filenamesList = new BindingList<FileName>(filelist); // <-- BindingList

    //Bind BindingList directly to the DataGrid, no need of BindingSource
    gvFilesOnServer.DataSource = filenamesList 
}

A piece of code is easier for people who have such problem. I share my code and you can use it directly. Please note that OpenCV store pixels as BGR.

cv::Mat vImage_; 

if(src_)
{
    cv::Vec3f vec_;

    for(int i = 0; i < vHeight_; i++)
        for(int j = 0; j < vWidth_; j++)
        {
            vec_ = cv::Vec3f((*src_)[0]/255.0, (*src_)[1]/255.0, (*src_)[2]/255.0);//Please note that OpenCV store pixels as BGR.

            vImage_.at<cv::Vec3f>(vHeight_-1-i, j) = vec_;

            ++src_;
        }
}

if(! vImage_.data ) // Check for invalid input
    printf("failed to read image by OpenCV.");
else
{
    cv::namedWindow( windowName_, CV_WINDOW_AUTOSIZE);
    cv::imshow( windowName_, vImage_); // Show the image.
}

Consider also passing in the shell variable (EMAILID) as a jq variable (here also EMAILID, for the sake of illustration):

   projectID=$(jq -r --arg EMAILID "$EMAILID" '
        .resource[]
        | select(.username==$EMAILID) 
        | .id' file.json)

Postscript

For the record, another possibility would be to use jq's env function for accessing environment variables. For example, consider this sequence of bash commands:

[email protected]  # not exported
EMAILID="$EMAILID" jq -n 'env.EMAILID'

The output is a JSON string:

"[email protected]"

This version trims internal whitespace and non-alphanumerics:

static inline std::string &trimAll(std::string &s)
{   
    if(s.size() == 0)
    {
        return s;
    }

    int val = 0;
    for (int cur = 0; cur < s.size(); cur++)
    {
        if(s[cur] != ' ' && std::isalnum(s[cur]))
        {
            s[val] = s[cur];
            val++;
        }
    }
    s.resize(val);
    return s;
}

Google recommend that you don't use any of them, source.

There is no need to use entity references like &mdash, &rdquo, or &#x263a, assuming the same encoding (UTF-8) is used for files and editors as well as among teams.

Is there a reason you can't simply use "?

After formatting the previous answer to my own code, I have found an efficient way to copy all necessary data if you are attempting to paste the values returned via AutoFilter to a separate sheet.

With .Range("A1:A" & LastRow)
    .Autofilter Field:=1, Criteria1:="=*" & strSearch & "*"
    .Offset(1,0).SpecialCells(xlCellTypeVisible).Cells.Copy
    Sheets("Sheet2").activate
    DestinationRange.PasteSpecial
End With

In this block, the AutoFilter finds all of the rows that contain the value of strSearch and filters out all of the other values. It then copies the cells (using offset in case there is a header), opens the destination sheet and pastes the values to the specified range on the destination sheet.

this solution work only .if your want to ignore this Warning

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:ignore="GoogleAppIndexingWarning"
    package="com.example.saloononlinesolution">

I'll start with your last question:

Why are these new categories needed?

The C++ standard contains many rules that deal with the value category of an expression. Some rules make a distinction between lvalue and rvalue. For example, when it comes to overload resolution. Other rules make a distinction between glvalue and prvalue. For example, you can have a glvalue with an incomplete or abstract type but there is no prvalue with an incomplete or abstract type. Before we had this terminology the rules that actually need to distinguish between glvalue/prvalue referred to lvalue/rvalue and they were either unintentionally wrong or contained lots of explaining and exceptions to the rule a la "...unless the rvalue is due to unnamed rvalue reference...". So, it seems like a good idea to just give the concepts of glvalues and prvalues their own name.

What are these new categories of expressions? How do these new categories relate to the existing rvalue and lvalue categories?

We still have the terms lvalue and rvalue that are compatible with C++98. We just divided the rvalues into two subgroups, xvalues and prvalues, and we refer to lvalues and xvalues as glvalues. Xvalues are a new kind of value category for unnamed rvalue references. Every expression is one of these three: lvalue, xvalue, prvalue. A Venn diagram would look like this:

    ______ ______
   /      X      \
  /      / \      \
 |   l  | x |  pr  |
  \      \ /      /
   \______X______/
       gl    r

Examples with functions:

int   prvalue();
int&  lvalue();
int&& xvalue();

But also don't forget that named rvalue references are lvalues:

void foo(int&& t) {
  // t is initialized with an rvalue expression
  // but is actually an lvalue expression itself
}

When you want to run an executable file from the Command prompt, (cmd.exe), or a batch file, it will:

• Search the current working directory for the executable file.
• Search all locations specified in the %PATH% environment variable for the executable file.

If the file isn't found in either of those options you will need to either:

1. Specify the location of your executable.
2. Change the working directory to that which holds the executable.
3. Add the location to %PATH% by apending it, (recommended only with extreme caution).

You can see which locations are specified in %PATH% from the Command prompt, Echo %Path%.

Because of your reported error we can assume that Mobile.exe is not in the current directory or in a location specified within the %Path% variable, so you need to use 1., 2. or 3..

Examples for 1.

C:\directory_path_without_spaces\My-App\Mobile.exe

or:

"C:\directory path with spaces\My-App\Mobile.exe"

Alternatively you may try:

Start C:\directory_path_without_spaces\My-App\Mobile.exe

or

Start "" "C:\directory path with spaces\My-App\Mobile.exe"

Where "" is an empty title, (you can optionally add a string between those doublequotes).

Examples for 2.

CD /D C:\directory_path_without_spaces\My-App
Mobile.exe

or

CD /D "C:\directory path with spaces\My-App"
Mobile.exe

You could also use the /D option with Start to change the working directory for the executable to be run by the start command

Start /D C:\directory_path_without_spaces\My-App Mobile.exe

or

Start "" /D "C:\directory path with spaces\My-App" Mobile.exe

You can use prettytable to render the table as text. The trick is to convert the data_frame to an in-memory csv file and have prettytable read it. Here's the code:

from StringIO import StringIO
import prettytable    

output = StringIO()
data_frame.to_csv(output)
output.seek(0)
pt = prettytable.from_csv(output)
print pt

I was able to use Find & Replace with the "Find what:" input field set to:

" * "

(space asterisk space with no double-quotes)

and "Replace with:" set to:

""

(nothing)

I finally found the reason,its becuse of the library can't find a CA bundle on your system. PHP >= v5.6 automatically sets verify_peer to true by default. However, not all systems have a known CA bundle on disk .

You can try one of these procedures:

1.If you have a CA file on your system, set openssl.cafile or curl.cainfo in your php.ini to the path of your CA file.

2.Manually specify your SSL CA file location

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);  
curl_setopt($cHandler, CURLOPT_CAINFO, $path-of-your-ca-file);

3.disabled verify_peer

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

After applying : Tools > preferences > Graphics > Backend > Automatic Just restart the kernel

And you will surely get Interactive Plot. Happy Coding!

JE and JZ are just different names for exactly the same thing: a conditional jump when ZF (the "zero" flag) is equal to 1.

(Similarly, JNE and JNZ are just different names for a conditional jump when ZF is equal to 0.)

You could use them interchangeably, but you should use them depending on what you are doing:

• JZ/JNZ are more appropriate when you are explicitly testing for something being equal to zero:

  dec  ecx
  jz   counter_is_now_zero
  

• JE and JNE are more appropriate after a CMP instruction:

  cmp  edx, 42
  je   the_answer_is_42
  

  (A CMP instruction performs a subtraction, and throws the value of the result away, while keeping the flags; which is why you get ZF=1 when the operands are equal and ZF=0 when they're not.)

the below code will do the job for you :

function indexes(source, find) {
  var result = [];
  for(i=0;i<str.length; ++i) {
    // If you want to search case insensitive use 
    // if (source.substring(i, i + find.length).toLowerCase() == find) {
    if (source.substring(i, i + find.length) == find) {
      result.push(i);
    }
  }
  return result;
}

indexes("hello, how are you", "ar")

With JUnit 5 I was able to solve this using the @RepeatedTest annotation:

@RepeatedTest(10)
public void testMyCode() {
    //your test code goes here
}

Note that @Test annotation shouldn't be used along with @RepeatedTest.

You can copy by inspect element and target the div you want to copy. Just press ctrl+c and then your div will be copy and paste in your code it will run easily.

Use:

+ scale_y_continuous(labels = scales::percent)

Or, to specify formatting parameters for the percent:

+ scale_y_continuous(labels = scales::percent_format(accuracy = 1))

(the command labels = percent is obsolete since version 2.2.1 of ggplot2)

There's only one error:

cout.cpp:26:29: error: no match for ‘operator<<’ in ‘std::operator<< [with _Traits = std::char_traits]((* & std::cout), ((const char*)"my structure ")) << m’

This means that the compiler couldn't find a matching overload for operator<<. The rest of the output is the compiler listing operator<< overloads that didn't match. The third line actually says this:

cout.cpp:26:29: note: candidates are:

Just use

composer require {package/packagename}

like

composer require phpmailer/phpmailer

if the package is not in the vendor folder.. composer installs it and if the package exists, composer update package to the latest version.

JavaScript has associative arrays.

Here is a working snippet.

<script type="text/javascript">
  var myArray = [];
  myArray['thank'] = 'you';
  myArray['no'] = 'problem';
  console.log(myArray);
</script>

They are simply called objects.

Check this. Also you can change it as per your preference.

It's pandas label-based selection, as explained here: https://pandas.pydata.org/pandas-docs/stable/indexing.html#selection-by-label

The boolean array is basically a selection method using a mask.

You use {} for grouping. The braces are required to dereference array elements. Example:

dir=(*)           # store the contents of the directory into an array
echo "${dir[0]}"  # get the first entry.
echo "$dir[0]"    # incorrect

Try <input type="number" step="0.01" /> if you are targeting 2 decimal places :-).

You have a lot of variants for using @RequestParam with additional optional elements, e.g.

@RequestParam(required = false, defaultValue = "someValue", value="someAttr") String someAttr

If you don't put required = false - param will be required by default.

defaultValue = "someValue" - the default value to use as a fallback when the request parameter is not provided or has an empty value.

If request and method param are the same - you don't need value = "someAttr"

You can use following formulas.

For Excel 2007 or later:

=IFERROR(VLOOKUP(D3,List!A:C,3,FALSE),"No Match")

For Excel 2003:

=IF(ISERROR(MATCH(D3,List!A:A, 0)), "No Match", VLOOKUP(D3,List!A:C,3,FALSE))

Note, that

• I'm using List!A:C in VLOOKUP and returns value from column ? 3
• I'm using 4th argument for VLOOKUP equals to FALSE, in that case VLOOKUP will only find an exact match, and the values in the first column of List!A:C do not need to be sorted (opposite to case when you're using TRUE).

Arrays.fill works with single dimensional array, so to fill two dimensional array we can do below

for (int i = 0, len = arr.length; i < len; i++)
    Arrays.fill(arr[i], 0);

this method also encounter a deprecate warning:

org.junit.Assert.assertEquals(float expected,float actual) //deprecated

It is because currently junit prefer a third parameter rather than just two float variables input.

The third parameter is delta:

public static void assertEquals(double expected,double actual,double delta) //replacement

this is mostly used to deal with inaccurate Floating point calculations

for more information, please refer this problem: Meaning of epsilon argument of assertEquals for double values

sometime it happens when you try to (run or create) a .jar file under /libs folder by right click it in android studio. you can select the dropdown in top of android stuio and change it to app. This will work

Just complementing @Jonsmoke's answer.

For API level 21 and above you can use :

android:backgroundTint="@android:color/white"

in XML for the button layout.

For API level below 21 use an AppCompatButton using app namespace instead of android for backgroundTint.

For example:

<android.support.v7.widget.AppCompatButton
    android:id="@+id/my_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="My Button"
    app:backgroundTint="@android:color/white" />

You need to set the text after the replace call:

$('.element span').each(function() {_x000D_
  console.log($(this).text());_x000D_
  var text = $(this).text().replace('N/A, ', '');_x000D_
  $(this).text(text);_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div class="element">_x000D_
  <span>N/A, Category</span>_x000D_
</div>

Here's another cool way you can do it (hat tip @Felix King):

$(".element span").text(function(index, text) {
    return text.replace("N/A, ", "");
});

After spent lot of hours, I just find out the solution, just add this simple line.

backgroundColor = .white

Hope this help you!

jQuery module can be installed using:

npm install jquery

Example:

var $ = require('jquery');
var http = require('http');

var options = {
    host: 'jquery.com',
    port: 80,
    path: '/'
};

var html = '';
http.get(options, function(res) {
res.on('data', function(data) {
    // collect the data chunks to the variable named "html"
    html += data;
}).on('end', function() {
    // the whole of webpage data has been collected. parsing time!
    var title = $(html).find('title').text();
    console.log(title);
 });
});

In simple words,

applicationContext.xml defines the beans that are shared among all the servlets. If your application have more than one servlet, then defining the common resources in the applicationContext.xml would make more sense.

spring-servlet.xml defines the beans that are related only to that servlet. Here it is the dispatcher servlet. So, your Spring MVC controllers must be defined in this file.

There is nothing wrong in defining all the beans in the spring-servlet.xml if you are running only one servlet in your web application.

In ECS6, one may use Array.from():

const listItems = document.querySelector('ul').children;
const listArray = Array.from(listItems);
listArray.forEach((item) => {console.log(item)});

An alternative to assume-unchanged is skip-worktree. The latter has a different meaning, something like "Git should not track this file. Developers can, and are encouraged, to make local changes."

In your situation where you do not wish to track changes to (typically large) build files, assume-unchanged is a good choice.

In the situation where the file should have default contents and the developer is free to modify the file locally, but should not check their local changes back to the remote repo, skip-worktree is a better choice.

Another elegant option is to have a default file in the repo. Say the filename is BuildConfig.Default.cfg. The developer is expected to rename this locally to BuildConfig.cfg and they can make whatever local changes they need. Now add BuildConfig.cfg to .gitignore so the file is untracked.

See this question which has some nice background information in the accepted answer.

In my case I saw the same message due to the different signatures of the installed apk and an uploaded to the market apk.

Apart from what Andy mentioned, there is another difference which could be important - write-host directly writes to the host and return nothing, meaning that you can't redirect the output, e.g., to a file.

---- script a.ps1 ----
write-host "hello"

Now run in PowerShell:

PS> .\a.ps1 > someFile.txt
hello
PS> type someFile.txt
PS>

As seen, you can't redirect them into a file. This maybe surprising for someone who are not careful.

But if switched to use write-output instead, you'll get redirection working as expected.

By default git revert refuses to revert a merge commit as what that actually means is ambiguous. I presume that your HEAD is in fact a merge commit.

If you want to revert the merge commit, you have to specify which parent of the merge you want to consider to be the main trunk, i.e. what you want to revert to.

Often this will be parent number one, for example if you were on master and did git merge unwanted and then decided to revert the merge of unwanted. The first parent would be your pre-merge master branch and the second parent would be the tip of unwanted.

In this case you could do:

git revert -m 1 HEAD

Every process running under the Linux kernel receives its own, unique environment that it inherits from its parent. In this case, the parent will be either a shell itself (spawning a sub shell), or the 'login' program (on a typical system).

As each process' environment is protected, there is no way to 'inject' an environmental variable to every running process, so even if you modify the default shell .rc / profile, it won't go into effect until each process exits and reloads its start up settings.

Look in /etc/ to modify the default start up variables for any particular shell. Just realize that users can (and often do) change them in their individual settings.

Unix is designed to obey the user, within limits.

NB: Bash is not the only shell on your system. Pay careful attention to what the /bin/sh symbolic link actually points to. On many systems, this could actually be dash which is (by default, with no special invocation) POSIXLY correct. Therefore, you should take care to modify both defaults, or scripts that start with /bin/sh will not inherit your global defaults. Similarly, take care to avoid syntax that only bash understands when editing both, aka avoiding bashisms.

According to MDN's article on Browser detection using the user agent, it is encouraged to avoid this approach if possible and suggest other avenues such as feature detection.

However, if one must use the user agent as a means to detect if the device is mobile, they suggest:

In summary, we recommend looking for the string “Mobi” anywhere in the User Agent to detect a mobile device.

Therefore, this one-liner will suffice:

const isMobileDevice = window.navigator.userAgent.toLowerCase().includes("mobi");

[UPDATE]:

As @zenw0lf suggests in the comments, using a Regular Expression would be better:

const isMobileDevice = /Mobi/i.test(window.navigator.userAgent)

As I said in the comment I left on gion_13 answer before (please read), you really can't. Not with javascript.

If you don't want the code to be available client-side (= stealable without great efforts), my suggestion would be to make use of PHP (ASP,Python,Perl,Ruby,JSP + Java-Servlets) that is processed server-side and only the results of the computation/code execution are served to the user. Or, if you prefer, even Flash or a Java-Applet that let client-side computation/code execution but are compiled and thus harder to reverse-engine (not impossible thus).

Just my 2 cents.

The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.

If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.

Note that when you insert into a List at a position, you are really inserting at a dynamic position within the List's current elements. See here:

      // use add() method to add elements in the list
      arrlist.add(15, 15);
      arrlist.add(22, 22);
      arrlist.add(30, 30);
      arrlist.add(40, 40);

      // adding element 25 at third position
      arrlist.add(2, 25);

      // let us print all the elements available in list
      for (Integer number : arrlist) {
         System.out.println("Number = " + number);
      }

This method has the benefit of allowing you to rank by a different column, and not trashing the other data. It's quite useful in a situation where you are trying to list orders with a column for items, listing the heaviest first.

reading an XML file and needs to download its schema

If you are counting on retrieving schemas or DTDs over the internet, you're building a slow, chatty, fragile application. What happens when that remote server hosting the file takes planned or unplanned downtime? Your app breaks. Is that OK?

See http://xml.apache.org/commons/components/resolver/resolver-article.html#s.catalog.files

URL's for schemas and the like are best thought of as unique identifiers. Not as requests to actually access that file remotely. Do some google searching on "XML catalog". An XML catalog allows you to host such resources locally, resolving the slowness, chattiness and fragility.

It's basically a permanently cached copy of the remote content. And that's OK, since the remote content will never change. If there's ever an update, it'd be at a different URL. Making the actual retrieval of the resource over the internet especially silly.

This should work, I tried it by myself and it worked for me. If you pass True instead of false, the print dialog will appear.

this.print(false);
