Where is the file that you're running? If it is in your public html folder, you can do echo dirname(__FILE__);

1. fork() - creates a new child process, which is a complete copy of the parent process. Child and parent processes use different virtual address spaces, which is initially populated by the same memory pages. Then, as both processes are executed, the virtual address spaces begin to differ more and more, because the operating system performs a lazy copying of memory pages that are being written by either of these two processes and assigns an independent copies of the modified pages of memory for each process. This technique is called Copy-On-Write (COW).
2. vfork() - creates a new child process, which is a "quick" copy of the parent process. In contrast to the system call fork(), child and parent processes share the same virtual address space. NOTE! Using the same virtual address space, both the parent and child use the same stack, the stack pointer and the instruction pointer, as in the case of the classic fork()! To prevent unwanted interference between parent and child, which use the same stack, execution of the parent process is frozen until the child will call either exec() (create a new virtual address space and a transition to a different stack) or _exit() (termination of the process execution). vfork() is the optimization of fork() for "fork-and-exec" model. It can be performed 4-5 times faster than the fork(), because unlike the fork() (even with COW kept in the mind), implementation of vfork() system call does not include the creation of a new address space (the allocation and setting up of new page directories).
3. clone() - creates a new child process. Various parameters of this system call, specify which parts of the parent process must be copied into the child process and which parts will be shared between them. As a result, this system call can be used to create all kinds of execution entities, starting from threads and finishing by completely independent processes. In fact, clone() system call is the base which is used for the implementation of pthread_create() and all the family of the fork() system calls.
4. exec() - resets all the memory of the process, loads and parses specified executable binary, sets up new stack and passes control to the entry point of the loaded executable. This system call never return control to the caller and serves for loading of a new program to the already existing process. This system call with fork() system call together form a classical UNIX process management model called "fork-and-exec".

This is what I use to clone a table structure (columns only)...

SELECT TOP 0 *
INTO NewTable
FROM TableStructureIWishToClone

This solution works(Tested):

type nul | more /e /p

This converts isolated line feeds to carriage return line feed combination.

A slightly more efficient version of the bytes2String method is

private static final char[] hex = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};
private static String byteArray2Hex(byte[] bytes) {
    StringBuilder sb = new StringBuilder(bytes.length * 2);
    for (final byte b : bytes) {
        sb.append(hex[(b & 0xF0) >> 4]);
        sb.append(hex[b & 0x0F]);
    }
    return sb.toString();
}

If you're looking for the Hierarchy Viewer tool, it has been changed to Layout Inspector:

https://developer.android.com/studio/debug/layout-inspector.html

document.documentElement.classList.add('myCssClass');

classList is supported since ie10: https://caniuse.com/#search=classlist

sudo /usr/bin/easy_install pip

this command worked out for me

Another alternative is to nest conditions

<ng-container *ngIf="foo === 1;else second"></ng-container>
<ng-template #second>
    <ng-container *ngIf="foo === 2;else third"></ng-container>
</ng-template>
<ng-template #third></ng-template>

If you are fine using a graphical tool this works very well:

gitk <file>

gitk now shows all commits where the file has been updated. Marking a commit will show you the diff against the previous commit in the list. This also works for directories, but then you also get to select the file to diff for the selected commit. Super useful!

mysql -u <user> -p -e "select * from schema.table"

Think about your user interface before you do this. I assume (though none of the answers has said so) that you'll be doing this when the document loads using jQuery's ready() function. If a user has already focussed on a different element before the document has loaded (which is perfectly possible) then it's extremely irritating for them to have the focus stolen away.

You could check for this by adding onfocus attributes in each of your <input> elements to record whether the user has already focussed on a form field and then not stealing the focus if they have:

var anyFieldReceivedFocus = false;

function fieldReceivedFocus() {
    anyFieldReceivedFocus = true;
}

function focusFirstField() {
    if (!anyFieldReceivedFocus) {
        // Do jQuery focus stuff
    }
}


<input type="text" onfocus="fieldReceivedFocus()" name="one">
<input type="text" onfocus="fieldReceivedFocus()" name="two">

I've found a way to solve the problem. This is a nasty hack but it works: open the doc with Open Office, then save it into any excel format; the resulting .xls or .xlsx will display the accentuated characters.

Simplest way:

jQuery(html).text();

That retrieves all the text from a string of html.

It means that the data variable is passing None (which is type NoneType), its equivalent for nothing. So it can't be iterable as a list, as you are trying to do.

Some more good commercial tools:

• Purify
• Insure++

Simple node script to get you going without too much hassle. Using readline to combine outputs so the lines don't get mangled.

const { spawn } = require('child_process');
const readline = require('readline');

[
  spawn('npm', ['run', 'start-watch']),
  spawn('npm', ['run', 'wp-server'])
].forEach(child => {
    readline.createInterface({
        input: child.stdout
    }).on('line', console.log);

    readline.createInterface({
        input: child.stderr,
    }).on('line', console.log);
});

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

Another way around this would be to insert a DEFAULT element in the other table. For example, any reference to uuid=00000000-0000-0000-0000-000000000000 on the other table would indicate no action. You also need to set all the values for that id to be "neutral", e.g. 0, empty string, null in order to not affect your code logic.

Your local port is using by another app. I faced the same problem! You can try the following step:

1. Go to command line and run it as administrator!

2. Type:

   netstat -ano | find ":5000"
   => TCP    0.0.0.0:5000           0.0.0.0:0              LISTENING       4032
      TCP    [::]:5000              [::]:0                 LISTENING       4032
   

3. Type:

   TASKKILL /F /PID 4032
   

=> SUCCESS: The process with PID 4032 has been terminated.

Note: My 5000 local port was listing by PID 4032. You should give yours!

In my use case, I wanted to asynchronously retrieve a url, and then follow that url to an external resource in a new window. A directive seemed overkill because I don't need reusability, so I simply did:

<button (click)="navigateToResource()">Navigate</button>

And in my component.ts

navigateToResource(): void {
  this.service.getUrl((result: any) => window.open(result.url));
}

Note:

Routing to a link indirectly like this will likely trigger the browser's popup blocker.

As of AngularJS v1.4.0, there is a built-in $httpParamSerializer service that converts any object to a part of a HTTP request according to the rules that are listed on the docs page.

It can be used like this:

$http.post('http://example.com', $httpParamSerializer(formDataObj)).
    success(function(data){/* response status 200-299 */}).
    error(function(data){/* response status 400-999 */});

Remember that for a correct form post, the Content-Type header must be changed. To do this globally for all POST requests, this code (taken from Albireo's half-answer) can be used:

$http.defaults.headers.post["Content-Type"] = "application/x-www-form-urlencoded";

To do this only for the current post, the headers property of the request-object needs to be modified:

var req = {
 method: 'POST',
 url: 'http://example.com',
 headers: {
   'Content-Type': 'application/x-www-form-urlencoded'
 },
 data: $httpParamSerializer(formDataObj)
};

$http(req);

Nope.

While in debug configuration there is a DEBUG defined constant (automatically defined by Visual Studio) while there is no such constant defined for release mode. Check your project settings under build.

Selecting [Define DEBUG constant] under Project -> Build is like including #define DEBUG at the beginning of every file.

If you want to define a RELEASE constant for the release configuration go to:

• Project Properties -> Build
• Select Release Mode
• in the Conditional compilation symbols textbox enter: RELEASE

Actually the answer is yes. Here is an example how you can do this: http://html5doctor.com/introducing-web-sql-databases/

The bad thing is that it's with very limited support by the browsers.

More information here HTML5 IndexedDB, Web SQL Database and browser wars

PS: As @Christoph said Web SQL is no longer in active maintenance and the Web Applications Working Group does not intend to maintain it further so look here https://developer.mozilla.org/en-US/docs/IndexedDB.

SQL.js

EDIT

As @clentfort said, you can access SQLite database with client-side JavaScript by using SQL.js.

To clear from the current position to the end of the current line, do this:

    public static void ClearToEndOfCurrentLine()
    {
        int currentLeft = Console.CursorLeft;
        int currentTop = Console.CursorTop;
        Console.Write(new String(' ', Console.WindowWidth - currentLeft));
        Console.SetCursorPosition(currentLeft, currentTop);
    }

Refer Below code which give the date in String form.

import java.text.SimpleDateFormat;
import java.util.Date;



public class Test{

    public static void main(String[] args) {
        long val = 1346524199000l;
        Date date=new Date(val);
        SimpleDateFormat df2 = new SimpleDateFormat("dd/MM/yy");
        String dateText = df2.format(date);
        System.out.println(dateText);
    }
}

Quote:

The "BIGINT(20)" specification isn't a digit limit. It just means that when the data is displayed, if it uses less than 20 digits it will be left-padded with zeros. 2^64 is the hard limit for the BIGINT type, and has 20 digits itself, hence BIGINT(20) just means everything less than 10^20 will be left-padded with spaces on display.

var specialChars = "<>@!#$%^&*()_+[]{}?:;|'\"\\,./~`-="
var check = function(string){
    for(i = 0; i < specialChars.length;i++){
        if(string.indexOf(specialChars[i]) > -1){
            return true
        }
    }
    return false;
}

if(check($('#Search').val()) == false){
    // Code that needs to execute when none of the above is in the string
}else{
    alert('Your search string contains illegal characters.');
}

You can use a FileOutputStream for this.

FileOutputStream fos = null;
try {
    fos = new FileOutputStream(new File("myFile")); 
    ByteArrayOutputStream baos = new ByteArrayOutputStream();

    // Put data in your baos

    baos.writeTo(fos);
} catch(IOException ioe) {
    // Handle exception here
    ioe.printStackTrace();
} finally {
    fos.close();
}

I use mostly 978px width for my designs. Adv. of 978px : can be divided by 2,3.

Today, in the year 2016, it is save to use document.querySelector without knowing the ID (especially if you have more than 2 radio buttons):

document.querySelector("input[name=main-categories]:checked").value

jsBin demo

1. You missed the order, first goes:

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.18/vue.min.js"></script>

and then:

<script>
    var demo = new Vue({
        el: '#demo',
        data: {
            message: 'Hello Vue.js!'
        }
    });
</script>

2. And type="JavaScript" should be type="text/javascript" (or rather nothing at all)

CMS has it right, but also if you use the server explorer in visual studio and play around with the performance counter tab then you can figure out how to get lots of useful metrics.

AngularJS's Filter worked out for me.

Assuming the code/id is unique, we can filter out that particular object with AngularJS's filter and work with the selected objects properties. Considering the example above:

<select ng-options="size.code as size.name for size in sizes" 
        ng-model="item.size.code" 
        ng-change="update(MAGIC_THING); search.code = item.size.code">
</select>

<!-- OUTSIDE THE SELECT BOX -->

<h1 ng-repeat="size in sizes | filter:search:true"
    ng-init="search.code = item.size.code">
  {{size.name}}
</h1>

Now, there are 3 important aspects to this:

1. ng-init="search.code = item.size.code" - on initializing h1 element outside select box, set the filter query to the selected option.

2. ng-change="update(MAGIC_THING); search.code = item.size.code" - when you change the select input, we'll run one more line which will set the "search" query to the currently selected item.size.code.

3. filter:search:true - Pass true to filter to enable strict matching.

That's it. If the size.code is uniqueID, we'll have only one h1 element with the text of size.name.

I've tested this in my project and it works.

Good Luck

A little alternative to @gasp´s answer is to simply put the actual domain name you are running it from. Docs: https://httpd.apache.org/docs/2.4/upgrading.html

In the following example, there is no authentication and all hosts in the example.org domain are allowed access; all other hosts are denied access.

Apache 2.2 configuration:

Order Deny,Allow
Deny from all
Allow from example.org

Apache 2.4 configuration:

Require host example.org

Recently I was helping a friend to find why their carousel was not working. Controls would not work and images were not transitioning. I had a working sample on a page I had used and we went through all the code including checking the items above in this post. We pasted the "good" carousel into the same page and it still worked. Now, all css and bootstrap files were the same for both. The code was now identical, so all we could try was the images.

So, we replaced the images with two that were working in my sample. It worked. We replaced the two images with the first two that were originally not working, and it worked. We added back each image (all jpegs) one-by-one, and when we got to the seventh image (of 18) and the carousel failed. Weird. We removed this one image and continued to add the remaining images until they were all added and the carousel worked.

for reference, we were using jquery-3.3.1.slim.min.js and bootstrap/4.3.1/js/bootstrap.min.js on this site.

I do not know why an image would or could cause a carousel to malfunction, but it did. I couldn't find a reference to this cause elsewhere either, so I'm posting here for posterity in the hope that it might help someone else when other solutions fail.

Test carousel with limited set of "known-to-be-good" images.

Simple Steps

1. 1 Open SQL Server Configuration Manager
2. Under SQL Server Services Select Your Server
3. Right Click and Select Properties
4. Log on Tab Change Built-in-account tick
5. in the drop down list select Network Service
6. Apply and start The service

In my version of Java JDK 1.8.0_05 -13%64=-13

you could try -13-(int(-13/64)) in other words do division cast to an integer to get rid of the fraction part then subtract from numerator So numerator-(int(numerator/denominator)) should give the correct remainder & sign

I had the same problem that occurred after I restored data from a postgres dumped db.

My dump file had the command below from where things started going south.

    SELECT pg_catalog.set_config('search_path', '', false);

Solutions:

1. Probably remove it or change that false to be true.
2. Create a private schema that will be used to access all the tables.

The command above simply deactivates all the publicly accessible schemas.

Check more on the documentation here: https://www.postgresql.org/docs/9.3/ecpg-connect.html

These will also redirect both:

yourcommand  &> /dev/null

yourcommand  >& /dev/null

though the bash manual says the first is preferred.

use android:theme="@android:style/Theme.NoTitleBar in manifest file's application tag to remove the title bar for whole application or put it in activity tag to remove the title bar from a single activity screen.

Use ng-value instead of value.

ng-value="true"

Version with ng-checked is worse because of the code duplication.

Use DateTime.ToString with the specified format MM.dd.yyyy:

this.TextBox3.Text = DateTime.Now.ToString("MM.dd.yyyy");

Here, MM means the month from 01 to 12, dd means the day from 01 to 31 and yyyy means the year as a four-digit number.

I faced this same issue when I needed to load location data that I had serialized into the database from the google places API. Generally I would want the whole thing so it works with maps but I didn't want to have to specify all of the fields every time.

I was working in Ruby so I can't give you the PHP implementation but the principle should be the same.

I defined a custom scalar type called JSON which just returns a literal JSON object.

The ruby implementation was like so (using graphql-ruby)

module Graph
  module Types
    JsonType = GraphQL::ScalarType.define do
      name "JSON"
      coerce_input -> (x) { x }
      coerce_result -> (x) { x }
    end
  end
end

Then I used it for our objects like so

field :location, Types::JsonType

I would use this very sparingly though, using it only where you know you always need the whole JSON object (as I did in my case). Otherwise it is defeating the object of GraphQL more generally speaking.

function is_session_started()

    if ( php_sapi_name() !== 'cli' ) {
        if ( version_compare(phpversion(), '5.4.0', '>=') ) {

        } else {
            return session_id() === '' ? FALSE : TRUE;
        }
    }
    return FALSE;
}

// Example

Use the CSS property list-style-position to position the bullet:

list-style-position:inside /* or outside */;

//declare the total variable
int total = 0;
//loop through the datagrid and sum the column 
for(int i=0;i<datagridview1.Rows.Count;i++)
{
    total +=int.Parse(datagridview1.Rows[i].Cells["CELL NAME OR INDEX"].Value.ToString());

}
string tota

$len = 10;   // total number of numbers
$min = 100;  // minimum
$max = 999;  // maximum
$range = []; // initialize array
foreach (range(0, $len - 1) as $i) {
    while(in_array($num = mt_rand($min, $max), $range));
    $range[] = $num;
}
print_r($range);

I was interested to see how the accepted answer stacks up against mine. It's useful to note, a hybrid of both may be advantageous; in fact a function that conditionally uses one or the other depending on certain values:

# The accepted answer
function randRange1($min, $max, $count)
{
    $numbers = range($min, $max);
    shuffle($numbers);
    return array_slice($numbers, 0, $count);
}

# My answer
function randRange2($min, $max, $count)
{
    $range = array();
    while ($i++ < $count) {
        while(in_array($num = mt_rand($min, $max), $range));
        $range[] = $num;
    }
    return $range;
}

echo 'randRange1: small range, high count' . PHP_EOL;
$time = microtime(true);
randRange1(0, 9999, 5000);
echo (microtime(true) - $time) . PHP_EOL . PHP_EOL;

echo 'randRange2: small range, high count' . PHP_EOL;
$time = microtime(true);
randRange2(0, 9999, 5000);
echo (microtime(true) - $time) . PHP_EOL . PHP_EOL;

echo 'randRange1: high range, small count' . PHP_EOL;
$time = microtime(true);
randRange1(0, 999999, 6);
echo (microtime(true) - $time) . PHP_EOL . PHP_EOL;

echo 'randRange2: high range, small count' . PHP_EOL;
$time = microtime(true);
randRange2(0, 999999, 6);
echo (microtime(true) - $time) . PHP_EOL . PHP_EOL;

The results:

randRange1: small range, high count
0.019910097122192

randRange2: small range, high count
1.5043621063232

randRange1: high range, small count
2.4722430706024

randRange2: high range, small count
0.0001051425933837

If you're using a smaller range and a higher count of returned values, the accepted answer is certainly optimal; however as I had expected, larger ranges and smaller counts will take much longer with the accepted answer, as it must store every possible value in range. You even run the risk of blowing PHP's memory cap. A hybrid that evaluates the ratio between range and count, and conditionally chooses the generator would be the best of both worlds.

The only real alternative here is to use some sort of custom widget with a modal option. Have a look at jQuery UI for an example of a dialog with these features. Similar things exist in just about every JS framework you can mention.

This is not possible as of May 2017, because Postman only works with HTTP methods such as POST, GET, PUT, DELETE.

P/S: There is a request for this if you want to upvote: github.com/postmanlabs/postman-app-support/issues/4009

Server.MapPath specifies the relative or virtual path to map to a physical directory.

• Server.MapPath(".")¹ returns the current physical directory of the file (e.g. aspx) being executed
• Server.MapPath("..") returns the parent directory
• Server.MapPath("~") returns the physical path to the root of the application
• Server.MapPath("/") returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)

An example:

Let's say you pointed a web site application (http://www.example.com/) to

C:\Inetpub\wwwroot

and installed your shop application (sub web as virtual directory in IIS, marked as application) in

D:\WebApps\shop

For example, if you call Server.MapPath() in following request:

http://www.example.com/shop/products/GetProduct.aspx?id=2342

then:

• Server.MapPath(".")¹ returns D:\WebApps\shop\products
• Server.MapPath("..") returns D:\WebApps\shop
• Server.MapPath("~") returns D:\WebApps\shop
• Server.MapPath("/") returns C:\Inetpub\wwwroot
• Server.MapPath("/shop") returns D:\WebApps\shop

If Path starts with either a forward slash (/) or backward slash (\), the MapPath() returns a path as if Path was a full, virtual path.

If Path doesn't start with a slash, the MapPath() returns a path relative to the directory of the request being processed.

Note: in C#, @ is the verbatim literal string operator meaning that the string should be used "as is" and not be processed for escape sequences.

Footnotes

1. Server.MapPath(null) and Server.MapPath("") will produce this effect too.

SELECT EXTRACT(YEAR FROM subdateshow) FROM tbl_name;

For Python 2 try:

print unicode(string, 'unicode-escape')

For Python 3 try:

string = "002 Could've Would've Should've"
os.system('echo ' + string)

Or try win-unicode-console:

pip install win-unicode-console

If you want to escape the data use

{{ $html }}

If don't want to escape the data use

{!! $html !!}

But till Laravel-4 you can use

{{ HTML::link('/auth/logout', 'Sign Out', array('class' => 'btn btn-default btn-flat')) }}

When comes to Laravel-5

{!! HTML::link('/auth/logout', 'Sign Out', array('class' => 'btn btn-default btn-flat')) !!} 

You can also do this with the PHP function

{{ html_entity_decode($data) }}

go through the PHP document for the parameters of this function

html_entity_decode - php.net

You can use =A4, in case A4 is having long formula

It is simple. The first thing that you have to understand the design of the Python interpreter. It doesn't allocate memory for all the variables basically if any two or more variable has the same value it just map to that value.

let's go to the code example,

In [6]: a = 10

In [7]: id(a)
Out[7]: 10914656

In [8]: b = 10

In [9]: id(b)
Out[9]: 10914656

In [10]: c = 11

In [11]: id(c)
Out[11]: 10914688

In [12]: d = 21

In [13]: id(d)
Out[13]: 10915008

In [14]: e = 11

In [15]: id(e)
Out[15]: 10914688

In [16]: e = 21

In [17]: id(e)
Out[17]: 10915008

In [18]: e is d
Out[18]: True
In [19]: e = 30

In [20]: id(e)
Out[20]: 10915296

From the above output, variables a and b shares the same memory, c and d has different memory when I create a new variable e and store a value (11) which is already present in the variable c so it mapped to that memory location and doesn't create a new memory when I change the value present in the variable e to 21 which is already present in the variable d so now variables d and e share the same memory location. At last, I change the value in the variable e to 30 which is not stored in any other variable so it creates a new memory for e.

so any variable which is having same value shares the memory.

Not for list and dictionary objects

let's come to your question.

when multiple keys have same value then all shares same memory so the thing that you expect is already there in python.

you can simply use it like this

In [49]: dictionary = {
    ...:     'k1':1,
    ...:     'k2':1,
    ...:     'k3':2,
    ...:     'k4':2}
    ...:     
    ...:     

In [50]: id(dictionary['k1'])
Out[50]: 10914368

In [51]: id(dictionary['k2'])
Out[51]: 10914368

In [52]: id(dictionary['k3'])
Out[52]: 10914400

In [53]: id(dictionary['k4'])
Out[53]: 10914400

From the above output, the key k1 and k2 mapped to the same address which means value one stored only once in the memory which is multiple key single value dictionary this is the thing you want. :P

Ok, I realize that this is a bit late... maybe this alternative wasn't available at the moment of writing the post?

Anyway, I've found installing the pos package via Fink (a prerequisite in this case, maybe there is something similar for those who uses MacPorts?) to be the easiest solution. You get two commands:

1. posd - which gives the current directory of the frontmost Finder window (for which you presumably make an alias cdf=cd posd)
2. fdc - which switches the current directory of the frontmost Finder window to the Terminal pwd. This is slightly different from 'open .' which always opens a new finder window.

Yes, you have to switch to the Terminal window before writing cdf, but I suppose that's quite cheap comparing to clicking a button in the Finder toolbar. And it works with iTerm as well, you don't have to download a separate Finder toolbar button that opens an iTerm window. This is the same approach as proposed by PCheese, but you don't have to clutter your .bash_profile.

You can define array size at runtime.

This will allow you to do whatever to dynamically compute the array's size. But, once defined the size is immutable.

Array a = Array.CreateInstance(typeof(string), 5);

du -S

du have another useful option: -S, --separate-dirs telling du not include size of subdirectories - handy on some occasions.

Example 1 - shows only the file sizes in a directory:

du -Sh  * 
3,1G    10/CR2
280M    10

Example 2 - shows the file sizes and subdirectories in directory:

du -h  * 
3,1G    10/CR2 
3,4G    10

I used ImportIO. They let you request the HTML from any website if you set up an account with them (which is free). They let you make up to 50k requests per year. I didn't take them time to find an alternative, but I'm sure there are some.

In your Javascript, you'll basically just make a GET request like this:

var request = new XMLHttpRequest();_x000D_
_x000D_
request.onreadystatechange = function() {_x000D_
  jsontext = request.responseText;_x000D_
_x000D_
  alert(jsontext);_x000D_
}_x000D_
_x000D_
request.open("GET", "https://extraction.import.io/query/extractor/THE_PUBLIC_LINK_THEY_GIVE_YOU?_apikey=YOUR_KEY&url=YOUR_URL", true);_x000D_
_x000D_
request.send();

Sidenote: I found this question while researching what I felt like was the same question, so others might find my solution helpful.

UPDATE: I created a new one which they just allowed me to use for less than 48 hours before they said I had to pay for the service. It seems that they shut down your project pretty quick now if you aren't paying. I made my own similar service with NodeJS and a library called NightmareJS. You can see their tutorial here and create your own web scraping tool. It's relatively easy. I haven't tried to set it up as an API that I could make requests to or anything.

It is not an anti-pattern to call setState in componentDidMount. In fact, ReactJS provides an example of this in their documentation:

You should populate data with AJAX calls in the componentDidMount lifecycle method. This is so you can use setState to update your component when the data is retrieved.

Example From Doc

componentDidMount() {
    fetch("https://api.example.com/items")
      .then(res => res.json())
      .then(
        (result) => {
          this.setState({
            isLoaded: true,
            items: result.items
          });
        },
        // Note: it's important to handle errors here
        // instead of a catch() block so that we don't swallow
        // exceptions from actual bugs in components.
        (error) => {
          this.setState({
            isLoaded: true,
            error
          });
        }
      )
  }

Create a bool isLoading and set it to false. With the help of ternary operator, When user clicks on login button set state of isLoading to true. You will get circular loading indicator in place of login button

 isLoading ? new PrimaryButton(
                      key: new Key('login'),
                      text: 'Login',
                      height: 44.0,
                      onPressed: setState((){isLoading = true;}))
                  : Center(
                      child: CircularProgressIndicator(),
                    ),

You can see Screenshots how it looks while before login is clicked

After login is clicked

In mean time you can run login process and login user. If user credentials are wrong then again you will setState of isLoading to false, such that loading indicator will become invisible and login button visible to user. By the way, primaryButton used in code is my custom button. You can do same with OnPressed in button.

I will elaborate on what robodo said in one of the comments above, a really quick and good looking and what is more important, responsive (not fixed height) approach that does not involve any hacks is to use flexbox. If you're not limited by browsers support it's a great solution.

HTML

<body>
  <div class="site-content">
    Site content
  </div>
  <footer class="footer">
    Footer content
  </footer>
</body>

CSS

html {
  height: 100%;
}
body {
  min-height: 100%;
  display: flex;
  flex-direction: column;
}
.site-content {
  flex: 1;
}

Browser support can be checked here: http://caniuse.com/#feat=flexbox

More common problem solutions using flexbox: https://github.com/philipwalton/solved-by-flexbox

std::list does not provide a search method. You can iterate over the list and check if the element exists or use std::find. But I think for your situation std::set is more preferable. The former will take O(n) time but later will take O(lg(n)) time to search.

You can simply use:

int my_var = 3;
std::set<int> mySet {1, 2, 3, 4};
if(mySet.find(myVar) != mySet.end()){
      //do whatever
}

char array[10];
snprintf(array, sizeof(array), "%f", 3.333333);

An alternative way can be this: - recommended as using just one expression -

case when address.country <> '' then address.country
else 'United States'
end as country

Note: Result of checking null by <> operator will return false.
And as documented: NULLIF is equivalent to a searched CASE expression
and COALESCE expression is a syntactic shortcut for the CASE expression.
So, combination of those are using two time of case expression.

If you don't want to do a full page refresh, then how about wrapping what you want to refresh inside of a UpdatePanel and then do an asynchronous postback?

Please find this example code, You could use hidden form with POST to send data to that your URL like below:

function open_win()
{
    var ChatWindow_Height = 650;
    var ChatWindow_Width = 570;

    window.open("Live Chat", "chat", "height=" + ChatWindow_Height + ", width = " + ChatWindow_Width);

    //Hidden Form
    var form = document.createElement("form");
    form.setAttribute("method", "post");
    form.setAttribute("action", "http://localhost:8080/login");
    form.setAttribute("target", "chat");

    //Hidden Field
    var hiddenField1 = document.createElement("input");
    var hiddenField2 = document.createElement("input");

    //Login ID
    hiddenField1.setAttribute("type", "hidden");
    hiddenField1.setAttribute("id", "login");
    hiddenField1.setAttribute("name", "login");
    hiddenField1.setAttribute("value", "PreethiJain005");

    //Password
    hiddenField2.setAttribute("type", "hidden");
    hiddenField2.setAttribute("id", "pass");
    hiddenField2.setAttribute("name", "pass");
    hiddenField2.setAttribute("value", "Pass@word$");

    form.appendChild(hiddenField1);
    form.appendChild(hiddenField2);

    document.body.appendChild(form);
    form.submit();

}

client.py

import socket

s = socket.socket()
s.connect(('127.0.0.1',12345))
while True:
    str = raw_input("S: ")
    s.send(str.encode());
    if(str == "Bye" or str == "bye"):
        break
    print "N:",s.recv(1024).decode()
s.close()

server.py

import socket

s = socket.socket()
port = 12345
s.bind(('', port))
s.listen(5)
c, addr = s.accept()
print "Socket Up and running with a connection from",addr
while True:
    rcvdData = c.recv(1024).decode()
    print "S:",rcvdData
    sendData = raw_input("N: ")
    c.send(sendData.encode())
    if(sendData == "Bye" or sendData == "bye"):
        break
c.close()

This should be the code for a small prototype for the chatting app you wanted. Run both of them in separate terminals but then just check for the ports.

Specially use this on newsletter -

<sup style="font-size:9px; line-height:8px;">&reg;</sup>

''.join(sequenceofstrings) is what usually works best -- simplest and fastest.

Example code for node.js - async function to sync function:

var deasync = require('deasync');

function syncFunc()
{
    var ret = null;
    asyncFunc(function(err, result){
        ret = {err : err, result : result}
    });

    while((ret == null))
    {
         deasync.runLoopOnce();
    }

    return (ret.err || ret.result);
}

Javascript

var clist = document.getElementsByTagName("input");
for (var i = 0; i < clist.length; ++i) { clist[i].checked = false; }

jQuery

$('input:checkbox').each(function() { this.checked = false; });

To do opposite, see: Select All Checkboxes By ID/Class

Try this:

$old_date = Date_create("2010-04-19 18:31:27");
$new_date = Date_format($old_date, "d/m/Y");

System.IO.DirectoryInfo myDirInfo = new DirectoryInfo(myDirPath);

foreach (FileInfo file in myDirInfo.GetFiles())
{
    file.Delete(); 
}
foreach (DirectoryInfo dir in myDirInfo.GetDirectories())
{
    dir.Delete(true); 
}

I'd do this:

1. add the dependency as you like in your pom:

   <dependency>
           <groupId>com.stackoverflow...</groupId>
           <artifactId>artifactId...</artifactId>
           <version>1.0</version>
   </dependency>
   

2. run mvn install it will try to download the jar and fail. On the process, it will give you the complete command of installing the jar with the error message. Copy that command and run it! easy huh?!

Well, you may try this '.*[0-9]'

2017 Update I guess. textarea worked fine for me using Spring, Bootstrap and a bunch of other things. Got the SOAP payload stored in a DB, read by Spring and push via Spring-MVC. xmp didn't work at all.

Supposing the form is the direct parent you can do:

<a href='#' onclick='this.parentNode.submit(); return false;'>submit</a>

If not you can access through the forms name attribute like this:

<a href='#' onclick='document.forms["myform"].submit(); return false;'>submit</a>

See both examples here: http://jsfiddle.net/WEZDC/1/

You can use this:

r'[a-z]+(?:-[a-z]+)*' 

I also wanted an email sent if the service was started this way so added a bit to @Ic code just thought I would post it in case it helped anyone. I used SendMail but there are other command line options How to send a simple email from a Windows batch file?

set service=MyServiceName

for /F "tokens=3 delims=: " %%H in ('sc query %service% ^| findstr "        STATE"') do (
  if /I "%%H" NEQ "RUNNING" (

    net start %service%

    for /F "tokens=3 delims=: " %%H in ('sc query %service% ^| findstr "        STATE"') do (
      if /I "%%H" EQ "RUNNING" (
        SendMail /smtpserver localhost /to [email protected] /from [email protected] /subject Service Autostart Notification /body Autostart on service %service% succeded.
      ) else (
        SendMail /smtpserver localhost /to [email protected] /from [email protected] /subject Service Autostart Notification /body Autostart on service %service% failed.
      )
    )

  )
)

Label's aren't form elements. They don't have a value. They have innerHTML and textContent.

Thus,

$('#telefon').html() 
// or
$('#telefon').text()

or

var telefon = document.getElementById('telefon');
telefon.innerHTML;

If you are starting with your form element, check out the labels list of it. That is,

var el = $('#myformelement');
var label = $( el.prop('labels') );
// label.html();
// el.val();
// blah blah blah you get the idea

The following signature will do:

List<Email> findByEmailIdInAndPincodeIn(List<String> emails, List<String> pinCodes);

Spring Data JPA supports a large number of keywords to build a query. IN and AND are among them.

In JavaScript functions are objects.

document.getElementById('foo').onclick = function(){
    prompt('Hello world');
}

Using only standard library distributed with Python:

import itertools

def nCk(n, k):
    return len(list(itertools.combinations(range(n), k)))

It's not difficult as we thing. Just create a frame for UIButton with clear background color, assign action for the button and place over the navigationbar back button. And finally remove the button after use.

Here is the Swift 3 sample code done with UIImage instead of UIButton

override func viewDidLoad() {
    super.viewDidLoad()
    let imageView = UIImageView()
    imageView.backgroundColor = UIColor.clear
    imageView.frame = CGRect(x:0,y:0,width:2*(self.navigationController?.navigationBar.bounds.height)!,height:(self.navigationController?.navigationBar.bounds.height)!)
    let tapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(back(sender:)))
    imageView.isUserInteractionEnabled = true
    imageView.addGestureRecognizer(tapGestureRecognizer)
    imageView.tag = 1
    self.navigationController?.navigationBar.addSubview(imageView)
    }

write the code need to be executed

func back(sender: UIBarButtonItem) {

    // Perform your custom actions}
    _ = self.navigationController?.popViewController(animated: true)

    }

Remove the subView after action is performed

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    for view in (self.navigationController?.navigationBar.subviews)!{
        if view.tag == 1 {
            view.removeFromSuperview()
        }
    }

Chrome browser considers integer value as return type not boolean value so,

this.state.data.sort((a, b) => a.item.timeM > b.item.timeM ? 1:-1).map(
    (item, i) => <div key={i}> {item.matchID} {item.timeM} {item.description}</div>
)

If you still want to show the item but make it not clickable and look disabled with CSS:

CSS:

.disabled {
    pointer-events:none; //This makes it not clickable
    opacity:0.6;         //This grays it out to look disabled
}

HTML:

<li class="disabled">Disabled List Item</li>

Also, if you are using BootStrap, they already have a class called disabled for this purpose. See this example.

As @LV98 pointed out, users could change this on the client side and submit a selection you weren't expecting. You will want to validate at the server as well.

Did you import it? Importing matplotlib is not enough.

>>> import matplotlib
>>> matplotlib.pyplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'pyplot'

but

>>> import matplotlib.pyplot
>>> matplotlib.pyplot

works.

pyplot is a submodule of matplotlib and not immediately imported when you import matplotlib.

The most common form of importing pyplot is

import matplotlib.pyplot as plt

Thus, your statements won't be too long, e.g.

plt.plot([1,2,3,4,5])

instead of

matplotlib.pyplot.plot([1,2,3,4,5])

And: pyplot is not a function, it's a module! So don't call it, use the functions defined inside this module instead. See my example above

To use session variables, it's necessary to start the session by using the session_start function, this will allow you to store your data in the global variable $_SESSION in a productive way.

so your code will finally look like this :

<strong>Test Form</strong>
<form action="" method"post">
<input type="text" name="picturenum"/>
<input type="submit" name="Submit" value="Submit!" />
</form>

<?php 
 
 // starting the session
 session_start();


 if (isset($_POST['Submit'])) { 
 $_SESSION['picturenum'] = $_POST['picturenum'];
 } 
?> 

<strong><?php echo $_SESSION['picturenum'];?></strong>

to make it easy to use and to avoid forgetting it again, you can create a session_file.php which you will want to be included in all your codes and will start the session for you:

session_start.php

 <?php
   session_start();
 ?> 

and then include it wherever you like :

<strong>Test Form</strong>
<form action="" method"post">
<input type="text" name="picturenum"/>
<input type="submit" name="Submit" value="Submit!" />
</form>

<?php 
 
 // including the session file
 require_once("session_start.php");


 if (isset($_POST['Submit'])) { 
 $_SESSION['picturenum'] = $_POST['picturenum'];
 } 
?> 

that way it is more portable and easy to maintain in the future.

other remarks

• if you are using Apache version 2 or newer, be careful. instead of
  <?
  to open php's tags, use <?php, otherwise your code will not be interpreted

• variables names in php are case-sensitive, instead of write $_session, write $_SESSION in capital letters

good work!

Beside all the guidance mentioned above,you can also check all the data.

If there are blanks between words, you must replace them with "_".

However that how I solve my own problem.

As alluded to in wickeD's answer, with replaceAll the replacement string is handled differently between replace and replaceAll. I expected a[3] and a[4] to have the same value, but they are different.

public static void main(String[] args) {
    String[] a = new String[5];
    a[0] = "\\";
    a[1] = "X";
    a[2] = a[0] + a[1];
    a[3] = a[1].replaceAll("X", a[0] + "X");
    a[4] = a[1].replace("X", a[0] + "X");

    for (String s : a) {
        System.out.println(s + "\t" + s.length());
    }
}

The output of this is:

\   1
X   1
\X  2
X   1
\X  2

This is different from perl where the replacement does not require the extra level of escaping:

#!/bin/perl
$esc = "\\";
$s = "X";

$s =~ s/X/${esc}X/;
print "$s " . length($s) . "\n";

which prints \X 2

This can be quite a nuisance, as when trying to use the value returned by java.sql.DatabaseMetaData.getSearchStringEscape() with replaceAll().

I implemented in this form in webview using fragment- inside oncreate:

 webView.setWebViewClient(new WebViewClient()
{
    public boolean shouldOverrideUrlLoading(WebView viewx, String urlx)
                {
     if(Uri.parse(urlx).getHost().endsWith("facebook.com")) {
                        {
                            goToFacebook();
                        }
                        return false;
                    }
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(urlx));
                    viewx.getContext().startActivity(intent);
                    return true;
                }

});

and outside onCreateView :

 private void goToFacebook() {
        try {
            String facebookUrl = getFacebookPageURL();
            Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
            facebookIntent.setData(Uri.parse(facebookUrl));
            startActivity(facebookIntent);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    //facebook url load
    private String getFacebookPageURL() {
        String FACEBOOK_URL = "https://www.facebook.com/pg/XXpagenameXX/";
        String facebookurl = null;

        try {
            PackageManager packageManager = getActivity().getPackageManager();

            if (packageManager != null) {
                Intent activated = packageManager.getLaunchIntentForPackage("com.facebook.katana");

                if (activated != null) {
                    int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;

                    if (versionCode >= 3002850) {
                        facebookurl = "fb://page/XXXXXXpage_id";
                    }
                } else {
                    facebookurl = FACEBOOK_URL;
                }
            } else {
                facebookurl = FACEBOOK_URL;
            }
        } catch (Exception e) {
            facebookurl = FACEBOOK_URL;
        }
        return facebookurl;
    }

open command prompt

python pip install <package-name> 

This should complete the process

I believe the problem is simply a spelling error when writing bbcode as bbocde:

$("#vinanghinguyen_images_bbocde").val('')

should be:

$("#vinanghinguyen_images_bbcode").val('')

You can do this in your code:

final ListView lv = (ListView) convertView.findViewById(R.id.list_view);

for (int i = 0; i < lv.getChildCount(); i++) {
    ((TextView)lv.getChildAt(i)).setTextColor(getResources().getColor(R.color.black));
}

An easy solution, if you've got ES6, uses Set:

function checkIfArrayIsUnique(myArray) {_x000D_
  return myArray.length === new Set(myArray).size;_x000D_
}_x000D_
_x000D_
let uniqueArray = [1, 2, 3, 4, 5];_x000D_
console.log(`${uniqueArray} is unique : ${checkIfArrayIsUnique(uniqueArray)}`);_x000D_
_x000D_
let nonUniqueArray = [1, 1, 2, 3, 4, 5];_x000D_
console.log(`${nonUniqueArray} is unique : ${checkIfArrayIsUnique(nonUniqueArray)}`);

The bit shift operators are more efficient as compared to the / or * operators.

In computer architecture, divide(/) or multiply(*) take more than one time unit and register to compute result, while, bit shift operator, is just one one register and one time unit computation.

use the relative path

main page might be: /index.html

secondary page: /otherFolder/otherpage.html

link would be like so:

<a href="/otherFolder/otherpage.html">otherpage</a>

Youtube doesn't provide any option for an end time, but there alternative sites that provide this, like Tubechop. Otherwise try writing a function that either pauses video/skips to next when your when your video has played its desired duration.

OR: using the Youtube Javascript player API, you could do something like this:

function onPlayerStateChange(evt) {
    if (evt.data == YT.PlayerState.PLAYING && !done) {
        setTimeout(stopVideo, 6000);
        done = true;
    }
}

I have just discovered and used FETCH_HEAD. I wanted a local copy of some software from a server and I did

git fetch gitserver release_1

gitserver is the name of my machine that stores git repositories. release_1 is a tag for a version of the software. To my surprise, release_1 was then nowhere to be found on my local machine. I had to type

 git tag release_1 FETCH_HEAD 

to complete the copy of the tagged chain of commits (release_1) from the remote repository to the local one. Fetch had found the remote tag, copied the commit to my local machine, had not created a local tag, but had set FETCH_HEAD to the value of the commit, so that I could find and use it. I then used FETCH_HEAD to create a local tag which matched the tag on the remote. That is a practical illustration of what FETCH_HEAD is and how it can be used, and might be useful to someone else wondering why git fetch doesn't do what you would naively expect.

In my opinion it is best avoided for that purpose and a better way to achieve what I was trying to do is

git fetch gitserver release_1:release_1

i.e. to fetch release_1 and call it release_1 locally. (It is source:dest, see https://git-scm.com/book/en/v2/Git-Internals-The-Refspec; just in case you'd like to give it a different name!)

You might want to use FETCH_HEAD at times though:-

git fetch gitserver bugfix1234
git cherry-pick FETCH_HEAD

might be a nice way of using bug fix number 1234 from your Git server, and leaving Git's garbage collection to dispose of the copy from the server once the fix has been cherry-picked onto your current branch. (I am assuming that there is a nice clean tagged commit containing the whole of the bug fix on the server!)

In my opinion simplest, C++ solution is:

bool endsWith(const string& s, const string& suffix)
{
    return s.rfind(suffix) == std::abs(s.size()-suffix.size());
}

Warning: If the match fails, this will search the entire string backwards before giving up, and thus potentially waste a lot of cycles.

Another approach would be to reset the form using JavaScript right after the form in the HTML:

<form id="myForm">
  <input type="text" value="" name="myTextInput" />
</form>

<script type="text/javascript">
  document.getElementById("myForm").reset();
</script>

You don't need to use JsonConverterAttribute, keep your model clean, also use CustomCreationConverter, the code is simpler:

public class SampleConverter : CustomCreationConverter<ISample>
{
    public override ISample Create(Type objectType)
    {
        return new Sample();
    }
}

Then:

var sz = JsonConvert.SerializeObject( sampleGroupInstance );
JsonConvert.DeserializeObject<SampleGroup>( sz, new SampleConverter());

If it is a new project simply you can do like this :

$ git clone --recurse-submodules https://github.com/chaconinc/YourProjectName 

If it is already installed than :

$ cd YourProjectName (for the cases you are not at right directory) 
$ git submodule init
$ git submodule update

Here is how to set a linearGradient on a target element:

<style type="text/css">
    path{fill:url('#MyGradient')}
</style>
<defs>
    <linearGradient id="MyGradient">
        <stop offset="0%" stop-color="#e4e4e3" ></stop>
        <stop offset="80%" stop-color="#fff" ></stop>
    </linearGradient>
</defs>

It's pretty trivial to implement with native addon, so someone did that: https://github.com/ErikDubbelboer/node-sleep.git

$sql="SELECT * FROM TABLE_NAME WHERE item_id=".$item_id;

$query=mysql_query($sql);

while($myrow=mysql_fetch_array($query)) {

echo   print_r($myrow,1);


}

Sometime ago I implemented an easy to use "download manager" library: PTDownloadManager. You could give it a shot!

One can access the "Find in Files" window via the drop-down menu selection and search all files in the Entire Solution: Edit > Find and Replace > Find in Files

Other, alternative is to open the "Find in Files" window via the "Standard Toolbars" button as highlighted in the below screen-short:

Arrow Function

The best and simplest way to solve this problem is by using an arrow function () => {}:

    addToBasket() {
        var item = this.photo;
        this.$http.post('/api/buy/addToBasket', item);
        this.basketAddSuccess = true;
        // now 'this' is referencing the Vue object and not the 'setTimeout' scope
        setTimeout(() => this.basketAddSuccess = false, 2000);
    }

This works because the this of arrow functions is bound to the this of its enclosing scope- in Vue, that's the parent/ enclosing component. Inside a traditional function called by setTimeout, however, this refers to the window object (which is why you ran into errors when you tried to access this.basketAddSuccess in that context).

Argument Passing

Another way of doing this would be passing this as an arg to your function through setTimeout's prototype using its setTimeout(callback, delay, arg1, arg2, ...) form:

    addToBasket() {
        item = this.photo;
        this.$http.post('/api/buy/addToBasket', item);
        this.basketAddSuccess = true;
        //Add scope argument to func, pass this after delay in setTimeout
        setTimeout(function(scope) {
             scope.basketAddSuccess = false;
        }, 2000, this);
    }

(It's worth noting that the arg passing syntax is incompatible with IE 9 and below, however.)

Apparently, other have (had) this problem. They rebuild in Framework 4.0. Can you?

Also, see this about making sure your IIS is fresh.

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

ngInit can help to initialize variables.

<div ng-app='app'>
    <div ng-controller="MyController" ng-init="myVar='test'">
        {{myVar}}
    </div>
</div>

jsfiddle example

When you call this:

data = Top15[['Citable docs per Capita','Energy Supply per Capita']]
correlation = data.corr(method='pearson')

Since, DataFrame.corr() function performs pair-wise correlations, you have four pair from two variables. So, basically you are getting diagonal values as auto correlation (correlation with itself, two values since you have two variables), and other two values as cross correlations of one vs another and vice versa.

Either perform correlation between two series to get a single value:

from scipy.stats.stats import pearsonr
docs_col = Top15['Citable docs per Capita'].values
energy_col = Top15['Energy Supply per Capita'].values
corr , _ = pearsonr(docs_col, energy_col)

or, if you want a single value from the same function (DataFrame's corr):

single_value = correlation[0][1] 

Hope this helps.

It's possible. You can set the locale. However, I would not recommend that. We've tried it at early stages, it's basically fighting the system.

We have the same requirement for changing the language but decided to settle to the fact that UI should be same as phone UI. It was working via setting locale but was too buggy. And you have to set it every time you enter activity (each activity) from my experience. here is a code if you still need this (again, I don't recommend that)

Resources res = context.getResources();
// Change locale settings in the app.
DisplayMetrics dm = res.getDisplayMetrics();
android.content.res.Configuration conf = res.getConfiguration();
conf.setLocale(new Locale(language_code.toLowerCase())); // API 17+ only.
// Use conf.locale = new Locale(...) if targeting lower versions
res.updateConfiguration(conf, dm);

If you have language specific content - you can change that base on the setting.

update on 26th of march 2020

    public static void setLocale(Activity activity, String languageCode) {
        Locale locale = new Locale(languageCode);
        Locale.setDefault(locale);
        Resources resources = activity.getResources();
        Configuration config = resources.getConfiguration();
        config.setLocale(locale);
        resources.updateConfiguration(config, resources.getDisplayMetrics());
    }

As per my answer here, it is also possible to use a table head (which can be empty) and apply relative widths for each table head cell. The widths of all cells in the table body will conform to the width of their column head. Example:

HTML

<table>
  <thead>
    <tr>
      <th width="5%"></th>
      <th width="70%"></th>
      <th width="15%"></th>
      <th width="10%"></th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>1</td>
      <td>Some text...</td>
      <td>May 2018</td>
      <td>Edit</td>
    </tr>
    <tr>
      <td>2</td>
      <td>Another text...</td>
      <td>April 2018</td>
      <td>Edit</td>
    </tr>
  </tbody>
</table>

CSS

table {
  width: 600px;
  border-collapse: collapse;
}

td {
  border: 1px solid #999999;
}

Alternatively, use colgroup as suggested in Hyathin's answer.

I just found my self with this Exception, I was trying to consume a JAX-WS, with a custom URL like this:

String WSDL_URL= <get value from properties file>;
Customer service = new Customer(new URL(WSDL_URL));
ExecutePtt port = service.getExecutePt();
return port.createMantainCustomers(part);

and Java threw:

XML reader error: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,63]
Message: White spaces are required between publicId and systemId.

Turns out that the URL string used to construct the service was missing the "?wsdl" at the end. For instance:

Bad:

http://www.host.org/service/Customer

Good:

http://www.host.org/service/Customer?wsdl

Assuming you want to simply lift the 32bits from one type and dump them as-is into the other type:

uint asUint = unchecked((uint)myInt);
int asInt = unchecked((int)myUint);

The destination type will blindly pick the 32 bits and reinterpret them.

Conversely if you're more interested in keeping the decimal/numerical values within the range of the destination type itself:

uint asUint = checked((uint)myInt);
int asInt = checked((int)myUint);

In this case, you'll get overflow exceptions if:

• casting a negative int (eg: -1) to an uint
• casting a positive uint between 2,147,483,648 and 4,294,967,295 to an int

In our case, we wanted the unchecked solution to preserve the 32bits as-is, so here are some examples:

Examples

int => uint

int....: 0000000000 (00-00-00-00)
asUint.: 0000000000 (00-00-00-00)
------------------------------
int....: 0000000001 (01-00-00-00)
asUint.: 0000000001 (01-00-00-00)
------------------------------
int....: -0000000001 (FF-FF-FF-FF)
asUint.: 4294967295 (FF-FF-FF-FF)
------------------------------
int....: 2147483647 (FF-FF-FF-7F)
asUint.: 2147483647 (FF-FF-FF-7F)
------------------------------
int....: -2147483648 (00-00-00-80)
asUint.: 2147483648 (00-00-00-80)

uint => int

uint...: 0000000000 (00-00-00-00)
asInt..: 0000000000 (00-00-00-00)
------------------------------
uint...: 0000000001 (01-00-00-00)
asInt..: 0000000001 (01-00-00-00)
------------------------------
uint...: 2147483647 (FF-FF-FF-7F)
asInt..: 2147483647 (FF-FF-FF-7F)
------------------------------
uint...: 4294967295 (FF-FF-FF-FF)
asInt..: -0000000001 (FF-FF-FF-FF)
------------------------------

Code

int[] testInts = { 0, 1, -1, int.MaxValue, int.MinValue };
uint[] testUints = { uint.MinValue, 1, uint.MaxValue / 2, uint.MaxValue };

foreach (var Int in testInts)
{
    uint asUint = unchecked((uint)Int);
    Console.WriteLine("int....: {0:D10} ({1})", Int, BitConverter.ToString(BitConverter.GetBytes(Int)));
    Console.WriteLine("asUint.: {0:D10} ({1})", asUint, BitConverter.ToString(BitConverter.GetBytes(asUint)));
    Console.WriteLine(new string('-',30));
}
Console.WriteLine(new string('=', 30));
foreach (var Uint in testUints)
{
    int asInt = unchecked((int)Uint);
    Console.WriteLine("uint...: {0:D10} ({1})", Uint, BitConverter.ToString(BitConverter.GetBytes(Uint)));
    Console.WriteLine("asInt..: {0:D10} ({1})", asInt, BitConverter.ToString(BitConverter.GetBytes(asInt)));
    Console.WriteLine(new string('-', 30));
}  

In some cases, i.e. when (if) you're just using float to have elements flow on the same "line", you might use

display: inline-block;

instead of

float: left;

Otherwise, using a clear element at the end works, even if it may go against the grain to need an element to do what should be CSS work.

To update a table in your .dbml-diagram with, for example, added columns, do this:

1. Update your SQL Server Explorer window.
2. Drag the "new" version of your table into the .dbml-diagram (report1 in the picture below).

3. Mark the added columns in the new version of the table, press Ctrl+C to copy the added columns.

4. Click the "old" version of your table and press Ctrl+V to paste the added columns into the already present version of the table.

If you want to just display some text in your .cshtml page, I do not recommend @Html.Label and also not to use the html label as well. The element represents a caption in a user interface. and you'll see that in the case of @Html.Label, a for attribute is added, referring to the id of a, possibly non-existent, element. The value of this attribute is the value of the model field, in which non-alphanumerics are replaced by underscores. You should use @Html.Display or @Html.DisplayFor, possibly wrapped in some plain html elements line span or p.

Try follow: Aspx:

<asp:TextBox ID="TextBox1" clientidmode="Static" runat="server" onkeypress="EnterEvent(event, someMethod)"></asp:TextBox>    
<asp:Button ID="Button1" onclick="someMethod()" runat="server" Text="Button" />

JS:

function EnterEvent(e, callback) {
        if (e.keyCode == 13) {
            callback();
        }
    }

Hopefully you have some luck here.

If you want to visualize the variations of a value across the screen, you can use a heatmap function similar to this (I wrote it in hlsl, but it is easy to adapt to glsl):

float4 HeatMapColor(float value, float minValue, float maxValue)
{
    #define HEATMAP_COLORS_COUNT 6
    float4 colors[HEATMAP_COLORS_COUNT] =
    {
        float4(0.32, 0.00, 0.32, 1.00),
        float4(0.00, 0.00, 1.00, 1.00),
        float4(0.00, 1.00, 0.00, 1.00),
        float4(1.00, 1.00, 0.00, 1.00),
        float4(1.00, 0.60, 0.00, 1.00),
        float4(1.00, 0.00, 0.00, 1.00),
    };
    float ratio=(HEATMAP_COLORS_COUNT-1.0)*saturate((value-minValue)/(maxValue-minValue));
    float indexMin=floor(ratio);
    float indexMax=min(indexMin+1,HEATMAP_COLORS_COUNT-1);
    return lerp(colors[indexMin], colors[indexMax], ratio-indexMin);
}

Then in your pixel shader you just output something like:

return HeatMapColor(myValue, 0.00, 50.00);

And can get an idea of how it varies across your pixels:

Of course you can use any set of colors you like.

ADB Build-Tools Will Not be downloaded automatically, by command android update sdk --no-ui

So for installing Buil-Tool type (in console):

android list sdk --all

Remember the number that is listed before the item and execute the following:

android update sdk -u --all --filter <number>

commands should be typed in /YourFolder/android-sdk-linux/tools

Also for remote folder (server opened by ssh for example) type:

**./android** list sdk --all
**./android** update sdk -u --all --filter <number>

For simple list of ADB packages type in terminal:

android list sdk

for install all packages:

android update sdk --no-ui

Or with filters (comma is separator):

android update sdk --no-ui --filter 3,5,8,14

May be I am oversimplifying?

Just add the following code:

Open sFileName For Input as iFileNum
Line Input #iFileNum, dummy1
Line Input #iFileNum, dummy2
........

Sundar

If you want to execute any procedure then firstly you have to set serveroutput on in the sqldeveloper work environment like.

->  SET SERVEROUTPUT ON;
-> BEGIN
dbms_output.put_line ('Hello World..');
dbms_output.put_line('Its displaying the values only for the Testing purpose');
END;

This is an intuitive solution using the viewport command that just sets the minimum height to the viewport height minus the footer height.

html,body{
height: 100%
}
#nonFooter{
min-height: calc(100vh - 30px)
}

#footer {
height:30px;
margin: 0;
clear: both;
width:100%;
}

The big thing is either the alias or the other password is wrong. Kindly check your passwords and your issue is solved. Incase you have forgotten password, you can recover it from the androidStuido3.0/System/Log ... Search for the keyword password and their you are saved

For example, like this:

const querystring = require('querystring');
const https = require('https');

var postData = querystring.stringify({
    'msg' : 'Hello World!'
});

var options = {
  hostname: 'posttestserver.com',
  port: 443,
  path: '/post.php',
  method: 'POST',
  headers: {
       'Content-Type': 'application/x-www-form-urlencoded',
       'Content-Length': postData.length
     }
};

var req = https.request(options, (res) => {
  console.log('statusCode:', res.statusCode);
  console.log('headers:', res.headers);

  res.on('data', (d) => {
    process.stdout.write(d);
  });
});

req.on('error', (e) => {
  console.error(e);
});

req.write(postData);
req.end();

If you are trying to delete a column which is a FOREIGN KEY, you must find the correct name which is not the column name. Eg: If I am trying to delete the server field in the Alarms table which is a foreign key to the servers table.

1. SHOW CREATE TABLE alarm; Look for the CONSTRAINT `server_id_refs_id_34554433` FORIEGN KEY (`server_id`) REFERENCES `server` (`id`) line.
2. ALTER TABLE `alarm` DROP FOREIGN KEY `server_id_refs_id_34554433`;
3. ALTER TABLE `alarm` DROP `server_id`

This will delete the foreign key server from the Alarms table.

Here's a ruby version of this:

def youtube_id(url)
   # Handles various YouTube URLs (youtube.com, youtube-nocookie.com, youtu.be), as well as embed links and urls with various parameters
   regex = /(?:youtube(?:-nocookie)?\.com\/(?:[^\/\n\s]+\/\S+\/|(?:v|vi|e(?:mbed)?)\/|\S*?[?&]v=|\S*?[?&]vi=)|youtu\.be\/)([a-zA-Z0-9_-]{11})/
   match = regex.match(url)
   if match && !match[1].nil?
      match[1]
   else
      nil
   end
end

To test the method:

example_urls = [

This answers what the OP should have asked, i.e. traverse a list comparing consecutive elements (excellent SilentGhost answer), yet generalized for any group (n-gram): 2, 3, ... n:

zip(*(l[start:] for start in range(0, n)))

Examples:

l = range(0, 4)  # [0, 1, 2, 3]

list(zip(*(l[start:] for start in range(0, 2)))) # == [(0, 1), (1, 2), (2, 3)]
list(zip(*(l[start:] for start in range(0, 3)))) # == [(0, 1, 2), (1, 2, 3)]
list(zip(*(l[start:] for start in range(0, 4)))) # == [(0, 1, 2, 3)]
list(zip(*(l[start:] for start in range(0, 5)))) # == []

Explanations:

• l[start:] generates a a list/generator starting from index start
• *list or *generator: passes all elements to the enclosing function zip as if it was written zip(elem1, elem2, ...)

Note:

AFAIK, this code is as lazy as it can be. Not tested.

From Git Bash I prefer to run the command:

git config --global credential.helper wincred

At that point running a command like git pull and entering your credentials one time should have it stored for future use. Git has a built-in credentials system that works in different OS environments. You can get more details here: 7.14 Git Tools - Credential Storage

I had the same problem. It was resolved by setting "USB computer connection" to "Camera (PTP)" instead of "Media Device (MTP)

The 64base method works for large images as well, I use that method to embed all the images into my website, and it works every time. I've done with files up to 2Mb size, jpg and png.

In the below investigation as API, I use http://example.com instead of http://myApiUrl/login from your question, because this first one working.

I assume that your page is on http://my-site.local:8088.

The reason why you see different results is that Postman:

• set header Host=example.com (your API)
• NOT set header Origin

This is similar to browsers' way of sending requests when the site and API has the same domain (browsers also set the header item Referer=http://my-site.local:8088, however I don't see it in Postman). When Origin header is not set, usually servers allow such requests by default.

This is the standard way how Postman sends requests. But a browser sends requests differently when your site and API have different domains, and then CORS occurs and the browser automatically:

• sets header Host=example.com (yours as API)
• sets header Origin=http://my-site.local:8088 (your site)

(The header Referer has the same value as Origin). And now in Chrome's Console & Networks tab you will see:

When you have Host != Origin this is CORS, and when the server detects such a request, it usually blocks it by default.

Origin=null is set when you open HTML content from a local directory, and it sends a request. The same situation is when you send a request inside an <iframe>, like in the below snippet (but here the Host header is not set at all) - in general, everywhere the HTML specification says opaque origin, you can translate that to Origin=null. More information about this you can find here.

fetch('http://example.com/api', {method: 'POST'});

Look on chrome-console > network tab

If you do not use a simple CORS request, usually the browser automatically also sends an OPTIONS request before sending the main request - more information is here. The snippet below shows it:

fetch('http://example.com/api', {_x000D_
  method: 'POST',_x000D_
  headers: { 'Content-Type': 'application/json'}_x000D_
});

Look in chrome-console -> network tab to 'api' request._x000D_
This is the OPTIONS request (the server does not allow sending a POST request)

You can change the configuration of your server to allow CORS requests.

Here is an example configuration which turns on CORS on nginx (nginx.conf file) - be very careful with setting always/"$http_origin" for nginx and "*" for Apache - this will unblock CORS from any domain.

location ~ ^/index\.php(/|$) {_x000D_
   ..._x000D_
    add_header 'Access-Control-Allow-Origin' "$http_origin" always;_x000D_
    add_header 'Access-Control-Allow-Credentials' 'true' always;_x000D_
    if ($request_method = OPTIONS) {_x000D_
        add_header 'Access-Control-Allow-Origin' "$http_origin"; # DO NOT remove THIS LINES (doubled with outside 'if' above)_x000D_
        add_header 'Access-Control-Allow-Credentials' 'true';_x000D_
        add_header 'Access-Control-Max-Age' 1728000; # cache preflight value for 20 days_x000D_
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';_x000D_
        add_header 'Access-Control-Allow-Headers' 'My-First-Header,My-Second-Header,Authorization,Content-Type,Accept,Origin';_x000D_
        add_header 'Content-Length' 0;_x000D_
        add_header 'Content-Type' 'text/plain charset=UTF-8';_x000D_
        return 204;_x000D_
    }_x000D_
}

Here is an example configuration which turns on CORS on Apache (.htaccess file)

You need to call setHasOptionsMenu(true) in onCreate().

For backwards compatibility it's better to place this call as late as possible at the end of onCreate() or even later in onActivityCreated() or something like that.

See: https://developer.android.com/reference/android/app/Fragment.html#setHasOptionsMenu(boolean)

This can happen after upgrading macOS. Try running git from a terminal and see if the error message begins with:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools) ...

If so the fix is to run

xcode-select --install

from the terminal. see this answer for more details

There exists various algorithms for the inverse cumulative normal distribution. The most popular in quantitative finance are tested on http://chasethedevil.github.io/post/monte-carlo-inverse-cumulative-normal-distribution/

In my opinion, there is not much incentive to use something else than algorithm AS241 from Wichura: it is machine precision, reliable and fast. Bottlenecks are rarely in the Gaussian random number generation.

The top answer here advocates for Box-Müller, you should be aware that it has known deficiencies. I quote https://www.sciencedirect.com/science/article/pii/S0895717710005935:

in the literature, Box–Muller is sometimes regarded as slightly inferior, mainly for two reasons. First, if one applies the Box–Muller method to numbers from a bad linear congruential generator, the transformed numbers provide an extremely poor coverage of the space. Plots of transformed numbers with spiraling tails can be found in many books, most notably in the classic book of Ripley, who was probably the first to make this observation"

You can't.

The result of the file dialog is not exposed to the browser.

Here if you mention .getPath() then that will return the path of Jar and I guess you will need its parent to refer to all other config files placed with the jar. This code works on Windows. Add the code within the main class.

File jarDir = new File(MyAppName.class.getProtectionDomain().getCodeSource().getLocation().getPath());
String jarDirpath = jarDir.getParent();

System.out.println(jarDirpath);

One of our guys does something similar with the filesystemresource. try

mvm.add("file", new FileSystemResource(pUploadDTO.getFile())); 

assuming the output of your .getFile is a java File object, that should work the same as ours, which just has a File parameter.

1. Check that you use ChromeDriver version that corresponds to your Chrome version
2. In case you are on Linux without graphical interface "headless" mode must be used

Example of WebDriverSettings.java :

...
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", chromePrefs);
options.addArguments("--no-sandbox");
options.addArguments("--headless"); //!!!should be enabled for Jenkins
options.addArguments("--disable-dev-shm-usage"); //!!!should be enabled for Jenkins
options.addArguments("--window-size=1920x1080"); //!!!should be enabled for Jenkins
driver = new ChromeDriver(options);
...

Works in windows 10, essentially identical to vanuan's answer, but cleaner (taken from somewhere, can't remember where..):

import sys
for p in sys.path:

It depends with the office you have installed, if you have x64 bit office then you must compile the application as a x64 to allow it to run, so if you want it to run on x36 then you must install office x86 to accept, i tried all the solutions above but none worked until when i realised i had office x64bit and so i built the application as x64 and worked

I have done the following on a Citrix XenDesktop VM, however you could just do this on your local PC:

Microsoft Virtual PC

If you are running Windows 7, you can download Microsoft virtual PC and create as many copies of Virtual PC as you need for testing without any licensing issues:

• http://www.microsoft.com/windows/virtual-pc/default.aspx

This requires no additional Windows licenses; you simply set up multiple machines with different browsers on them. You can run the browsers out of the window by following the tutorial available here:

• http://ieblog.members.winisp.net/images/InstallingXPMode.htm

Installing Browsers

You will need to create at least 3 virtual PC's (tip: keep the memory down to 256mb for each virtual PC to avoid wasting memory on the virtual desktops).

On the first VPC I installed this:

• http://tredosoft.com/Multiple_IE

along with Chrome 1, Safari 3.1, Opera 8.

On the second I installed Internet Explorer 7, Chrome 3, Safari 3.2.1, Opera 9.

On the third I installed Internet Explorer 8, Chrome 8. Safari 4.0.5, Opera 10.

On Windows 7 (native machine) I had Internet Explorer 9, Chrome 11, Safari 5, Opera 11 and for Firefox I install the following app natively too:

• http://utilu.com/UtiluMFC/

Personally I would not go back further than 5 years with compatibility (other than IE for government networks) unless you have a specific requirement (I split Chrome & Opera across years as I decided there were just to many releases). However, if you find that someone has a specific issue with a site using a specific version of the browser it becomes very easy to install additional virtual machines to run additional browser versions.

Obtaining Older Browsers

You can download older versions of Chrome from here:

• http://www.oldapps.com/google_chrome.php

and Opera here:

• http://www.oldapps.com/opera.php

Virtualizing The Test Platform (Optional)

I use Xen Desktop to virtualize the testing platform so that I can use it anywhere and have included my favorite development tools on there as well:

• http://deliver.citrix.com/go/citrix/XenDesktop

The express edition is available for free.

A Good Commercial Alternative

Another great product I recently came accross is Stylizer which is a CSS editor that installs multiple versions of browsers for testing purposes, however this is a commercial paid for product but is very good and worth the small fee they require to run it.

Google's Closure Templates is a natively-JavaScript templating system and a seemingly natural fit with NodeJS. Here are some instructions for integrating them.

Using the @Override annotation acts as a compile-time safeguard against a common programming mistake. It will throw a compilation error if you have the annotation on a method you're not actually overriding the superclass method.

The most common case where this is useful is when you are changing a method in the base class to have a different parameter list. A method in a subclass that used to override the superclass method will no longer do so due the changed method signature. This can sometimes cause strange and unexpected behavior, especially when dealing with complex inheritance structures. The @Override annotation safeguards against this.

A boolean is not an integer; 1 and 0 are not boolean values in Java. You'll need to convert them explicitly:

boolean multipleContacts = (1 == jsonObject.getInt("MultipleContacts"));

or serialize the ints as booleans from the start.

You will need to prevent default form behaviour on submit. After that you will need to submit form programmatically in case of Ok button is selected.

Here is how it could look like:

document.querySelector('#from1').addEventListener('submit', function(e) {
  var form = this;

  e.preventDefault(); // <--- prevent form from submitting

  swal({
      title: "Are you sure?",
      text: "You will not be able to recover this imaginary file!",
      icon: "warning",
      buttons: [
        'No, cancel it!',
        'Yes, I am sure!'
      ],
      dangerMode: true,
    }).then(function(isConfirm) {
      if (isConfirm) {
        swal({
          title: 'Shortlisted!',
          text: 'Candidates are successfully shortlisted!',
          icon: 'success'
        }).then(function() {
          form.submit(); // <--- submit form programmatically
        });
      } else {
        swal("Cancelled", "Your imaginary file is safe :)", "error");
      }
    })
});

_{UPD. Example above uses sweetalert v2.x promise API.}

This error occurs when versions of NodeJS and Node Sass are not matched.

you can resolve your issue by doing as below:

- Step 1: Remove Nodejs from your computer

- Step 2: Reinstall Nodejs version 14.15.1.

- Step 3: Uninstall Node sass by run the command npm uninstall node-sass

- Step 4: Reinstall Node sass version 4.14.1 by run the command npm install [email protected]

After all steps, you can run command ng serve -o to run your application.

Node sass version 5.0.0 is incompatible with ^4.0.0.

There are no events in JQuery to detect css changes.
Refer here: onHide() type event in jQuery
It is possible:

DOM L2 Events module defines mutation events; one of them - DOMAttrModified is the one you need. Granted, these are not widely implemented, but are supported in at least Gecko and Opera browsers.
Source: Event detect when css property changed using Jquery

Without events, you can use setInterval function, like this:

var maxTime = 5000, // 5 seconds
    startTime = Date.now();

var interval = setInterval(function () {
        if ($('#element').is(':visible')) {
            // visible, do something
            clearInterval(interval);
        } else {
            // still hidden
            if (Date.now() - startTime > maxTime) {
                // hidden even after 'maxTime'. stop checking.
                clearInterval(interval);
            }
        }
    },
    100 // 0.1 second (wait time between checks)
);

Note that using setInterval this way, for keeping a watch, may affect your page's performance.

7th July 2018:
Since this answer is getting some visibility and up-votes recently, here is additional update on detecting css changes:

Mutation Events have been now replaced by the more performance friendly Mutation Observer.

The MutationObserver interface provides the ability to watch for changes being made to the DOM tree. It is designed as a replacement for the older Mutation Events feature which was part of the DOM3 Events specification.

Refer: https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver

When you do : f.readlines() you already read all the file so f.tell() will show you that you are in the end of the file, and doing f.next() will result in a StopIteration error.

Alternative of what you want to do is:

filne = "D:/testtube/testdkanimfilternode.txt"

with open(filne, 'r+') as f:
    for line in f:
        if line.startswith("anim "):
            print f.next() 
            # Or use next(f, '') to return <empty string> instead of raising a  
            # StopIteration if the last line is also a match.
            break

I faced the same problem, I added android support design dependencies to the app level build.gradle

Add following:

implementation 'com.android.support:design:27.1.0'

in build.gradle. Now its working for me.

You have your arguments to the remote add command reversed:

git remote add <NAME> <PATH>

So:

git remote add bak /home/sas/dev/apps/smx/repo/bak/ontologybackend/.git

See git remote --help for more information.

You need to install ssh2 lib

sudo apt-get install libssh2-php && sudo /etc/init.d/apache2 restart

that should be enough to get you on the road

 DataClassesDataContext dc = new DataClassesDataContext();

 FamilyDetail fd = dc.FamilyDetails.Single(p => p.UserId == 1);

 fd.FatherName=txtFatherName.Text;
        fd.FatherMobile=txtMobile.Text;
        fd.FatherOccupation=txtFatherOccu.Text;
        fd.MotherName=txtMotherName.Text;
        fd.MotherOccupation=txtMotherOccu.Text;
        fd.Phone=txtPhoneNo.Text;
        fd.Address=txtAddress.Text;
        fd.GuardianName=txtGardianName.Text;

        dc.SubmitChanges();

Click on the drop down next to the Run button, After that choose Run Configuration, shows three option, for example i choose java application add class(Name of the class of your project) in that then Click on the ok button ...Run your application :)

This method works in Chrome and IE:

<a href="blablabla" onclick="setTimeout(function(){var ww = window.open(window.location, '_self'); ww.close(); }, 1000);">
    If you click on this the window will be closed after 1000ms

If you're using .NET 3.5 or .NET 4, it's easy to create the dictionary using LINQ:

Dictionary<string, ArrayList> result = target.GetComponents()
                                      .ToDictionary(x => x.Key, x => x.Value);

There's no such thing as an IEnumerable<T1, T2> but a KeyValuePair<TKey, TValue> is fine.

eldNew <- eld[-14,]

See ?"[" for a start ...

For ‘[’-indexing only: ‘i’, ‘j’, ‘...’ can be logical vectors, indicating elements/slices to select. Such vectors are recycled if necessary to match the corresponding extent. ‘i’, ‘j’, ‘...’ can also be negative integers, indicating elements/slices to leave out of the selection.

edit: looking around I notice How to delete the first row of a dataframe in R? , which has the answer ... seems like the title should have popped to your attention if you were looking for answers on SO?

In the previous answers Code coverage has been explained well . I am just adding some knowledge related to tools if your are working on iOS and OSX platforms, Xcode provides the facility to test and monitor code coverage.

Reference Links:

https://developer.apple.com/library/archive/documentation/DeveloperTools/Conceptual/testing_with_xcode/chapters/07-code_coverage.html

https://medium.com/zendesk-engineering/code-coverage-and-xcode-6b2fb8756a51

Both are helpful links for learning and exploring code coverage with Xcode.

To ignore any changes to all the files (of a certain type) in a directory, I had to combine some of these approaches, otherwise the files were created if they didn't previously exist.

In the below, "excludedir" is the name of the directory that I wish to not watch changes to.

First, remove any existing new files from your change tracking cache (without removing from your file system).

git status | grep "new file:" | cut  --complement -d " " -f1-4 | grep "^excludedir" | xargs git rm --cache

You can do the same with modified:. renamed: is a bit more complicated, as you'll have to look at the post -> bit for the new filename, and do the pre -> bit as described for deleted: below.

deleted: files prove a bit more complicated, as you can't seem to update-index for a file that doesn't exist on the local system

echo .deletedfiles >> .gitignore
git status | grep "deleted:" | cut  --complement -d " " -f1-4 | grep "^excludedir" > .deletedfiles
cat .deletedfiles | xargs -d '\n' touch
cat .deletedfiles | xargs -d '\n' git add -f
cat .deletedfiles | xargs -d '\n' git update-index --assume-unchanged
cat .deletedfiles | xargs -d '\n' rm

The last command in the list above will remove the files again from your file system, so feel free to omit that.

Then, block change tracking from that directory

git ls-files excludedir/ | xargs git update-index --skip-worktree
git update index --skip-worktree excludedir/

I was getting the exact same error for forgetting to remove the .class extension when running the JAVA class. So instead of this:

java myClass.class

One should do this:

java myClass

the above code for chrome is working fine. i have tried like this in mozila but its not working. i found the solution for that

For mozila

input[type=number] { 
  -moz-appearance: textfield;
  appearance: textfield;
  margin: 0; 
}

Thanks Sanjib

Below step solved my issue:

Open CMD Prompt with Admin Privileges.

Run : iisreset.

Hope this helps.

Well, if you gonna present alternate optimization, we can also go for an iterator:

 static IEnumerable<DateTime> RandomDay()
 {
    DateTime start = new DateTime(1995, 1, 1);
    Random gen = new Random();
    int range = ((TimeSpan)(DateTime.Today - start)).Days;
    while (true)
        yield return  start.AddDays(gen.Next(range));        
}

you could use it like this:

int i=0;
foreach(DateTime dt in RandomDay())
{
    Console.WriteLine(dt);
    if (++i == 10)
        break;
}

I think it should be:

dataGridView1.Columns[0].HeaderCell.Value = "my text";

There is at least one way, but it's not a very good one. You could just poll the element for changes like this:

var previous_style,
    poll = window.setInterval(function()
{
    var current_style = document.getElementById('target').style.display;
    if (previous_style != current_style) {
        alert('style changed');
        window.clearInterval(poll);
    } else {
        previous_style = current_style;
    }
}, 100);

The DOM standard also specifies mutation events, but I've never had the chance to use them, and I'm not sure how well they're supported. You'd use them like this:

target.addEventListener('DOMAttrModified', function()
{
    if (e.attrName == 'style') {
        alert('style changed');
    }
}, false);

This code is off the top of my head, so I'm not sure if it'd work.

The best and easiest solution would be to have a callback in the function displaying your target.

You need to use ContextCompat.getColor(), which is part of the Support V4 Library (so it will work for all the previous API).

ContextCompat.getColor(context, R.color.my_color)

As specified in the documentation, "Starting in M, the returned color will be styled for the specified Context's theme". SO no need to worry about it.

You can add the Support V4 library by adding the following to the dependencies array inside your app build.gradle:

compile 'com.android.support:support-v4:23.0.1'

aca definis los anchos

 float[] anchoDeColumnas= new float[] {10f, 20f, 30f, 10f};

aca se los insertas a la tabla que tiene las columnas

table.setWidths(anchoDeColumnas);

Try this in your model:

function order_summary_insert()
    $OrderLines=$this->input->post('orderlines');
    $CustomerName=$this->input->post('customer');
    $data = array(
        'OrderLines'=>$OrderLines,
        'CustomerName'=>$CustomerName
    );

    $this->db->insert('Customer_Orders',$data);
}

Try to use controller just to control the view and models always post your values in model. it makes easy to understand. Your controller will be:

function new_blank_order_summary() {
    $this->sales_model->order_summary_insert($data);
    $this->load->view('sales/new_blank_order_summary');
}

You could declare a table variable (Declaring a variable of type table):

declare @MonthsSale table(monthnr int)
insert into @MonthsSale (monthnr) values (1)
insert into @MonthsSale (monthnr) values (2)
....

You can add extra columns as you like:

declare @MonthsSale table(monthnr int, totalsales tinyint)

You can update the table variable like any other table:

update m
set m.TotalSales = sum(s.SalesValue)
from @MonthsSale m
left join Sales s on month(s.SalesDt) = m.MonthNr

Try this one on for size.

This edits the system class loader to include the given library jar. It is pretty ugly, but it works.

(this assumes that ~ does not occur in file)

^\w{14}$ in Perl and any Perl-style regex.

If you want to learn more about regular expressions - or just need a handy reference - the Wikipedia Entry on Regular Expressions is actually pretty good.

You can try lubridate package which makes life much easier

library(lubridate)

mdy_hms(mydate)

The above will change the date format to POSIXct

A sample working example:

> data <- "1/15/2006 01:15:00"
> library(lubridate)
> mydate <- mdy_hms(data)
> mydate
[1] "2006-01-15 01:15:00 UTC"
> class(mydate)
[1] "POSIXct" "POSIXt" 

For case with factor use as.character

data <- factor("1/15/2006 01:15:00")
library(lubridate)
mydate <- mdy_hms(as.character(data))

To index-based access to the pandas table, one can also consider numpy.as_array option to convert the table to Numpy array as

np_df = df.as_matrix()

and then

np_df[i] 

would work.

For me it was really silly I had created a ModelClass file without the .php extension. So calling that was giving model not found. So check the extension has .php

MySQL prior to version 8.0 doesn't support the WITH clause (CTE in SQL Server parlance; Subquery Factoring in Oracle), so you are left with using:

• TEMPORARY tables
• DERIVED tables
• inline views (effectively what the WITH clause represents - they are interchangeable)

The request for the feature dates back to 2006.

As mentioned, you provided a poor example - there's no need to perform a subselect if you aren't altering the output of the columns in any way:

  SELECT * 
    FROM ARTICLE t
    JOIN USERINFO ui ON ui.user_userid = t.article_ownerid
    JOIN CATEGORY c ON c.catid =  t.article_categoryid
   WHERE t.published_ind = 0
ORDER BY t.article_date DESC 
   LIMIT 1, 3

Here's a better example:

SELECT t.name,
       t.num
  FROM TABLE t
  JOIN (SELECT c.id
               COUNT(*) 'num'
          FROM TABLE c
         WHERE c.column = 'a'
      GROUP BY c.id) ta ON ta.id = t.id

The below code reads a file, converts it to a byte array and then makes a request to the server.

    public void PostImage()
    {
        HttpClient httpClient = new HttpClient();
        MultipartFormDataContent form = new MultipartFormDataContent();

        byte[] imagebytearraystring = ImageFileToByteArray(@"C:\Users\Downloads\icon.png");
        form.Add(new ByteArrayContent(imagebytearraystring, 0, imagebytearraystring.Count()), "profile_pic", "hello1.jpg");
        HttpResponseMessage response = httpClient.PostAsync("your url", form).Result;

        httpClient.Dispose();
        string sd = response.Content.ReadAsStringAsync().Result;
    }

    private byte[] ImageFileToByteArray(string fullFilePath)
    {
        FileStream fs = File.OpenRead(fullFilePath);
        byte[] bytes = new byte[fs.Length];
        fs.Read(bytes, 0, Convert.ToInt32(fs.Length));
        fs.Close();
        return bytes;
    }

Also note that Scala extends String with a number of methods (via implicit conversion to a WrappedString brought in by Predef) so you could also do the following:

val formattedString = "Hello %s, isn't %s cool?".format("Ivan", "Scala")

if you want to use gitk:

gitk master..branch-X

it has a nice old school GUi

You can call handleInputs() add in your submit function before ajax

function handleInputs(){
    $('input[type=checkbox]').each(function() {     
        if (!this.checked) {
            $(this).attr("value","0");
        }else{
            $(this).attr("value","1");
        }
    });
}

It is perfectly working

1)your id should have sys dba access 2)

select sum(a.value) total_cur, avg(a.value) avg_cur, max(a.value) max_cur, 
 s.username, s.machine
 from v$sesstat a, v$statname b, v$session s 
 where a.statistic# = b.statistic# and s.sid=a.sid
 and b.name = 'opened cursors current' 
 group by s.username, s.machine
 order by 1 desc;

On greedy vs non-greedy

Repetition in regex by default is greedy: they try to match as many reps as possible, and when this doesn't work and they have to backtrack, they try to match one fewer rep at a time, until a match of the whole pattern is found. As a result, when a match finally happens, a greedy repetition would match as many reps as possible.

The ? as a repetition quantifier changes this behavior into non-greedy, also called reluctant (in e.g. Java) (and sometimes "lazy"). In contrast, this repetition will first try to match as few reps as possible, and when this doesn't work and they have to backtrack, they start matching one more rept a time. As a result, when a match finally happens, a reluctant repetition would match as few reps as possible.

Example 1: From A to Z

Let's compare these two patterns: A.*Z and A.*?Z.

Given the following input:

eeeAiiZuuuuAoooZeeee

The patterns yield the following matches:

• A.*Z yields 1 match: AiiZuuuuAoooZ (see on rubular.com)
• A.*?Z yields 2 matches: AiiZ and AoooZ (see on rubular.com)

Let's first focus on what A.*Z does. When it matched the first A, the .*, being greedy, first tries to match as many . as possible.

eeeAiiZuuuuAoooZeeee
   \_______________/
    A.* matched, Z can't match

Since the Z doesn't match, the engine backtracks, and .* must then match one fewer .:

eeeAiiZuuuuAoooZeeee
   \______________/
    A.* matched, Z still can't match

This happens a few more times, until finally we come to this:

eeeAiiZuuuuAoooZeeee
   \__________/
    A.* matched, Z can now match

Now Z can match, so the overall pattern matches:

eeeAiiZuuuuAoooZeeee
   \___________/
    A.*Z matched

By contrast, the reluctant repetition in A.*?Z first matches as few . as possible, and then taking more . as necessary. This explains why it finds two matches in the input.

Here's a visual representation of what the two patterns matched:

eeeAiiZuuuuAoooZeeee
   \__/r   \___/r      r = reluctant
    \____g____/        g = greedy

Example: An alternative

In many applications, the two matches in the above input is what is desired, thus a reluctant .*? is used instead of the greedy .* to prevent overmatching. For this particular pattern, however, there is a better alternative, using negated character class.

The pattern A[^Z]*Z also finds the same two matches as the A.*?Z pattern for the above input (as seen on ideone.com). [^Z] is what is called a negated character class: it matches anything but Z.

The main difference between the two patterns is in performance: being more strict, the negated character class can only match one way for a given input. It doesn't matter if you use greedy or reluctant modifier for this pattern. In fact, in some flavors, you can do even better and use what is called possessive quantifier, which doesn't backtrack at all.

Example 2: From A to ZZ

This example should be illustrative: it shows how the greedy, reluctant, and negated character class patterns match differently given the same input.

eeAiiZooAuuZZeeeZZfff

These are the matches for the above input:

• A[^Z]*ZZ yields 1 match: AuuZZ (as seen on ideone.com)
• A.*?ZZ yields 1 match: AiiZooAuuZZ (as seen on ideone.com)
• A.*ZZ yields 1 match: AiiZooAuuZZeeeZZ (as seen on ideone.com)

Here's a visual representation of what they matched:

         ___n
        /   \              n = negated character class
eeAiiZooAuuZZeeeZZfff      r = reluctant
  \_________/r   /         g = greedy
   \____________/g

One greedy repetition can outgreed another

• Regex not being greedy enough
• Regular expression: who's greedier

I use the following steps to solve the problem:

First, Make sure

“Run this program in compatibality mode for: Windows XP (Service Pack 3)” and “Run this program as an administrator” are ENABLED.

Run in Command Prompt

C:\Users\{yourusernamehere}\Documents\Downloads\netbeans-6.5-ml-windows.exe –-javahome "C:\Program Files (x86)\Java\jdk1.6.0_18"

Clarifying it. Model:

public class ContactUsModel
{
    public string FirstName { get; set; }             
    public string LastName { get; set; }              
    public string Email { get; set; }                 
    public string Phone { get; set; }                 
    public HttpPostedFileBase attachment { get; set; }

Post Action

public virtual ActionResult ContactUs(ContactUsModel Model)
{
 if (Model.attachment.HasFile())
 {
   //save the file

   //Send it as an attachment 
    Attachment messageAttachment = new Attachment(Model.attachment.InputStream,       Model.attachment.FileName);
  }
}

Finally the Extension method for checking the hasFile

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace AtlanticCMS.Web.Common
{
     public static class ExtensionMethods 
     {
         public static bool HasFile(this HttpPostedFileBase file)
         {
             return file != null && file.ContentLength > 0;
         }        
     }
 }

There is a combination of techniques which I found useful in solving this issue:

with open(file, 'r+') as fd:
    contents = fd.readlines()
    contents.insert(index, new_string)  # new_string should end in a newline
    fd.seek(0)  # readlines consumes the iterator, so we need to start over
    fd.writelines(contents)  # No need to truncate as we are increasing filesize

In our particular application, we wanted to add it after a certain string:

with open(file, 'r+') as fd:
    contents = fd.readlines()
    if match_string in contents[-1]:  # Handle last line to prevent IndexError
        contents.append(insert_string)
    else:
        for index, line in enumerate(contents):
            if match_string in line and insert_string not in contents[index + 1]:
                contents.insert(index + 1, insert_string)
                break
    fd.seek(0)
    fd.writelines(contents)

If you want it to insert the string after every instance of the match, instead of just the first, remove the else: (and properly unindent) and the break.

Note also that the and insert_string not in contents[index + 1]: prevents it from adding more than one copy after the match_string, so it's safe to run repeatedly.

You can use TreeMap which internally implements the SortedMap below is the example

Sorting by ascending ordering :

  Map<Float, String> ascsortedMAP = new TreeMap<Float, String>();

  ascsortedMAP.put(8f, "name8");
  ascsortedMAP.put(5f, "name5");
  ascsortedMAP.put(15f, "name15");
  ascsortedMAP.put(35f, "name35");
  ascsortedMAP.put(44f, "name44");
  ascsortedMAP.put(7f, "name7");
  ascsortedMAP.put(6f, "name6");

  for (Entry<Float, String> mapData : ascsortedMAP.entrySet()) {
    System.out.println("Key : " + mapData.getKey() + "Value : " + mapData.getValue());
  }

Sorting by descending ordering :

If you always want this create the map to use descending order in general, if you only need it once create a TreeMap with descending order and put all the data from the original map in.

  // Create the map and provide the comparator as a argument
  Map<Float, String> dscsortedMAP = new TreeMap<Float, String>(new Comparator<Float>() {
    @Override
    public int compare(Float o1, Float o2) {
      return o2.compareTo(o1);
    }
  });
  dscsortedMAP.putAll(ascsortedMAP);
