Another possible case (but rare) could be if you have server to server communications and have set server.maxConnections to a very low value.

In node's core lib net.js it will call clientHandle.close() which will also cause error ECONNRESET:

if (self.maxConnections && self._connections >= self.maxConnections) {
  clientHandle.close(); // causes ECONNRESET on the other end
  return;
}

You can't assign a process output directly into a var, you need to parse the output with a For /F loop:

@Echo OFF

FOR /F "Tokens=2,*" %%A IN (
    'Reg Query "HKEY_CURRENT_USER\Software\Macromedia\FlashPlayer" /v "CurrentVersion"'
) DO (
    REM Set "Version=%%B"
    Echo Version: %%B
)

Pause&Exit

PS: Change the reg key used if needed.

The web.config transforms that are part of Visual Studio 2010 use XSLT in order to "transform" the current web.config file into its .Debug or .Release version.

In your .Debug/.Release files, you need to add the following parameter in your connection string fields:

xdt:Transform="SetAttributes" xdt:Locator="Match(name)"

This will cause each connection string line to find the matching name and update the attributes accordingly.

Note: You won't have to worry about updating your providerName parameter in the transform files, since they don't change.

Here's an example from one of my apps. Here's the web.config file section:

<connectionStrings>
      <add name="EAF" connectionString="[Test Connection String]" />
</connectionString>

And here's the web.config.release section doing the proper transform:

<connectionStrings>
      <add name="EAF" connectionString="[Prod Connection String]"
           xdt:Transform="SetAttributes"
           xdt:Locator="Match(name)" />
</connectionStrings>

One added note: Transforms only occur when you publish the site, not when you simply run it with F5 or CTRL+F5. If you need to run an update against a given config locally, you will have to manually change your Web.config file for this.

For more details you can see the MSDN documentation

https://msdn.microsoft.com/en-us/library/dd465326(VS.100).aspx

To specify a variable is an array of objects:

$needles = getAllNeedles();
/* @var $needles Needle[] */
$needles[1]->...                        //codehinting works

This works in Netbeans 7.2 (I'm using it)

Works also with:

$needles = getAllNeedles();
/* @var $needles Needle[] */
foreach ($needles as $needle) {
    $needle->...                        //codehinting works
}

Therefore use of declaration inside the foreach is not necessary.

Just use square brackets instead:

print arr[1,1]

In Swift 3, there is no need for completion handler when DispatchQueue finishes one task. Furthermore you can achieve your goal in different ways

One way is this:

    var a: Int?

    let queue = DispatchQueue(label: "com.app.queue")
    queue.sync {

        for  i in 0..<10 {

            print("??" , i)
            a = i
        }
    }

    print("After Queue \(a)")

It will wait until the loop finishes but in this case your main thread will block.

You can also do the same thing like this:

    let myGroup = DispatchGroup()
    myGroup.enter()
    //// Do your task

    myGroup.leave() //// When your task completes
     myGroup.notify(queue: DispatchQueue.main) {

        ////// do your remaining work
    }

One last thing: If you want to use completionHandler when your task completes using DispatchQueue, you can use DispatchWorkItem.

Here is an example how to use DispatchWorkItem:

let workItem = DispatchWorkItem {
    // Do something
}

let queue = DispatchQueue.global()
queue.async {
    workItem.perform()
}
workItem.notify(queue: DispatchQueue.main) {
    // Here you can notify you Main thread
}

This has to be done during your exe4j configuration. In the fourth step of Exe4j wizard which is Executable Info select> Advanced options select 32-bit or 64-bit. This worked well for me. or else install both JDK tool-kits x64 and x32 in your machine.

The following works for me:

<!-- https://mvnrepository.com/artifact/org.apache.poi/poi -->

ob_start();  // turns on output buffering
$foo->bar();  // all output goes only to buffer
ob_clean();  // delete the contents of the buffer, but remains buffering active
$foo->render(); // output goes to buffer
ob_flush(); // send buffer output
$none = ob_get_contents();  // buffer content is now an empty string
ob_end_clean();  // turn off output buffering

Buffers can be nested, so while one buffer is active, another ob_start() activates a new buffer. So ob_end_flush() and ob_flush() are not really sending the buffer to the output, but to the parent buffer. And only when there is no parent buffer, contents is sent to browser or terminal.

Nicely explained here: https://phpfashion.com/everything-about-output-buffering-in-php

Here's my solution:

def un_camel(text):
    """ Converts a CamelCase name into an under_score name. 

        >>> un_camel('CamelCase')
        'camel_case'
        >>> un_camel('getHTTPResponseCode')
        'get_http_response_code'
    """
    result = []
    pos = 0
    while pos < len(text):
        if text[pos].isupper():
            if pos-1 > 0 and text[pos-1].islower() or pos-1 > 0 and \
            pos+1 < len(text) and text[pos+1].islower():
                result.append("_%s" % text[pos].lower())
            else:
                result.append(text[pos].lower())
        else:
            result.append(text[pos])
        pos += 1
    return "".join(result)

It supports those corner cases discussed in the comments. For instance, it'll convert getHTTPResponseCode to get_http_response_code like it should.

Convert the integer to string first, and then use map to apply int on it:

>>> num = 132
>>> map(int, str(num))    #note, This will return a map object in python 3.
[1, 3, 2]

or using a list comprehension:

>>> [int(x) for x in str(num)]
[1, 3, 2]

In principle, I agree with Ignacio, above, but you can also use type to check if something is a tuple or a list.

>>> a = (1,)
>>> type(a)
(type 'tuple')
>>> a = [1]
>>> type(a)
(type 'list')

It is easy. C++11 provides an easy way to sum up elements of a vector.

sum = 0; 
vector<int> vec = {1,2,3,4,5,....}
for(auto i:vec) 
   sum+=i;
cout<<" The sum is :: "<<sum<<endl; 

Note that if you're targeting node.js you can use Buffer.from(string).length:

var str = "\u2620"; // => "?"
str.length; // => 1 (character)
Buffer.from(str).length // => 3 (bytes)

You can do this way, providing Json or Any other variable:

1) For exemple, in the controller, you can use Json.NET to provide Json to the ViewBag:

ViewBag.Number = 10;
ViewBag.FooObj = JsonConvert.SerializeObject(new Foo { Text = "Im a foo." });

2) In the View, put the script like this at the bottom of the page.

<script type="text/javascript">
    var number = parseInt(@ViewBag.Number); //Accessing the number from the ViewBag
    alert("Number is: " + number);
    var model = @Html.Raw(@ViewBag.FooObj); //Accessing the Json Object from ViewBag
    alert("Text is: " + model.Text);
</script> 

Style

.not-focusable:focus {
    outline: none;
    box-shadow: none;
}

Using

<button class="btn btn-primary not-focusable">My Button</button>

$(document).ready(function() {
  $('td').on('click', function() {
    var value = $this.text();
  });
});

public void keyPressed(KeyEvent e) {
    int keyCode = e.getKeyCode();
    switch( keyCode ) { 
        case KeyEvent.VK_UP:
            // handle up 
            break;
        case KeyEvent.VK_DOWN:
            // handle down 
            break;
        case KeyEvent.VK_LEFT:
            // handle left
            break;
        case KeyEvent.VK_RIGHT :
            // handle right
            break;
     }
} 

try this. (I modified the example on the purpose of making it non trivial)

import operator
import numpy as np

n=10
a = list(range(n))
a1 = [1]*len(a)
an = np.array(a)

operator.add is almost more than two times faster

%timeit map(operator.add, a, a1)

than adding with numpy

%timeit an+1

LDAPService should contain method like LDAPService.isExists(String userName) use it to prevent NPE to be thrown. If is not - this could be a workaround, but use Logging to post some warning..

The answer by Carles is the correct answer, but few of the methods like getDrawable(), getColor() got deprecated at the time I am writing this answer. So the updated answer would be

Drawable upArrow = ContextCompat.getDrawable(context, R.drawable.abc_ic_ab_back_mtrl_am_alpha);
upArrow.setColorFilter(ContextCompat.getColor(context, R.color.white), PorterDuff.Mode.SRC_ATOP);
getSupportActionBar().setHomeAsUpIndicator(upArrow);

Following some other stackoverflow queries I found that calling ContextCompat.getDrawable() is similar to

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    return resources.getDrawable(id, context.getTheme());
} else {
    return resources.getDrawable(id);
}

And ContextCompat.getColor() is similar to

public static final int getColor(Context context, int id) {
    final int version = Build.VERSION.SDK_INT;
    if (version >= 23) {
        return ContextCompatApi23.getColor(context, id);
    } else {
        return context.getResources().getColor(id);
    }
}

Link 1: ContextCompat.getDrawable()

Link 2: ContextCompat.getColor()

I have a very quick and simple workaround here, it does work for me, and no matter the event would be triggered once or twice or more times occasionally, check it out:

private int fireCount = 0;
private void inputFileWatcher_Changed(object sender, FileSystemEventArgs e)
    {
       fireCount++;
       if (fireCount == 1)
        {
            MessageBox.Show("Fired only once!!");
            dowork();
        }
        else
        {
            fireCount = 0;
        }
    }
}

SET  @num := 0;

UPDATE your_table SET id = @num := (@num+1);

ALTER TABLE your_table AUTO_INCREMENT =1;

I think this will do it

td.description {vertical-align: top;}

where description is the class name of the td with that text in it

td.description {_x000D_
  vertical-align: top;_x000D_
}

<td class="description">Description</td>

OR inline (yuk!)

<td style="vertical-align: top;">Description</td>

You should put the button inside a div, and in the div you should be able to use the classes:
text-left, text-center and text-right.

for example:

<div class="row">
   <div class="col text-center">
      <button class="button button-small button-light">Search</button>
   </div>
</div>

And about the "textarea" position:

<div class="list">
<label class="item item-input">
    <span class="input-label">Date</span>
    <input type="text" placeholder="Text Area">
</label>

Demo using your code:
http://codepen.io/douglask/pen/zxXvYY

On Windows : !pip install opencv-python

like already said, in java-8 we have the concise solution by Collectors:

  list.stream().collect(
         groupingBy(Item::getKey)
        )

and also, you can nest multiple group passing an other groupingBy method as second parameter:

  list.stream().collect(
         groupingBy(Item::getKey, groupingBy(Item::getOtherKey))
        )

In this way, we'll have multi level map, like this: Map<key, Map<key, List<Item>>>

just go to the window bottom tray click on wamp icon ,click mysql->my.ini,then there is option ;sql-mode="" uncomment this make it like sql-mode="" and restart wamp worked for me

and has lower precedence than &&.

But for an unassuming user, problems might occur if it is used along with other operators whose precedence are in between, for example, the assignment operator:

def happy?() true; end
def know_it?() true; end

todo = happy? && know_it? ? "Clap your hands" : "Do Nothing"

todo
# => "Clap your hands"

todo = happy? and know_it? ? "Clap your hands" : "Do Nothing"

todo
# => true

Try this.

It boils down to adding android:stretchColumns="*" to your TableLayout root and setting android:layout_width="0dp" to all the children in your TableRows.

<TableLayout
    android:stretchColumns="*"   // Optionally use numbered list "0,1,2,3,..."
>
    <TableRow
        android:layout_width="0dp"
    >

You can try the following method(python3.6.2):

case one:

@app.route('/hello')
def hello():

    headers={ 'content-type':'text/plain' ,'location':'http://www.stackoverflow'}
    response = make_response('<h1>hello world</h1>',301)
    response.headers = headers
    return response

case two:

@app.route('/hello')
def hello():

    headers={ 'content-type':'text/plain' ,'location':'http://www.stackoverflow.com'}
    return '<h1>hello world</h1>',301,headers

I am using Flask .And if you want to return json,you can write this:

import json # 
@app.route('/search/<keyword>')
def search(keyword):

    result = Book.search_by_keyword(keyword)
    return json.dumps(result),200,{'content-type':'application/json'}


from flask import jsonify
@app.route('/search/<keyword>')
def search(keyword):

    result = Book.search_by_keyword(keyword)
    return jsonify(result)

JavaScript

$scope.get_pre = function(x) {
    return $sce.trustAsHtml(x);
};

HTML

<pre ng-bind-html="get_pre(html)"></pre>

I faced the same issue as the OP. It was taking my old Git credentials stored somewhere on the system and I wanted to use Git with my new credentials, so I ran the command

$ git config --system --list

It showed

credential.helper=manager

Whenever I performed git push it was taking my old username which I set long back, and I wanted to use new a GitHub account to push changes. I later found that my old GitHub account credentials was stored under Control Panel ? User Accounts ? Credential Manager ? Manage Windows Credentials.

I just removed these credentials and when I performed git push it asked me for my GitHub credentials, and it worked like a charm.

You need to set the height on the <html> and <body> elements as well; otherwise, they will only be large enough to fit the content. For example:

<!DOCTYPE html>_x000D_
<title>Example of 100% width and height</title>_x000D_
<style>_x000D_
html, body { height: 100%; margin: 0; }_x000D_
div { height: 100%; width: 100%; background: red; }_x000D_
</style>_x000D_
<div></div>

200 is just the normal HTTP header for a successful request. If that's all you need, just have the controller return new EmptyResult();

There isn't a single answer to this question as there are too many variables, but SHA2 is not yet really cracked (see: Lifetimes of cryptographic hash functions) so it is still a good algorithm to use to store passwords in. The use of salt is good because it prevents attack from dictionary attacks or rainbow tables. Importance of a salt is that it should be unique for each password. You can use a format like [128-bit salt][512-bit password hash] when storing the hashed passwords.

The only viable way to attack is to actually calculate hashes for different possibilities of password and eventually find the right one by matching the hashes.

To give an idea about how many hashes can be done in a second, I think Bitcoin is a decent example. Bitcoin uses SHA256 and to cut it short, the more hashes you generate, the more bitcoins you get (which you can trade for real money) and as such people are motivated to use GPUs for this purpose. You can see in the hardware overview that an average graphic card that costs only $150 can calculate more than 200 million hashes/s. The longer and more complex your password is, the longer time it will take. Calculating at 200M/s, to try all possibilities for an 8 character alphanumberic (capital, lower, numbers) will take around 300 hours. The real time will most likely less if the password is something eligible or a common english word.

As such with anything security you need to look at in context. What is the attacker's motivation? What is the kind of application? Having a hash with random salt for each gives pretty good protection against cases where something like thousands of passwords are compromised.

One thing you can do is also add additional brute force protection by slowing down the hashing procedure. As you only hash passwords once, and the attacker has to do it many times, this works in your favor. The typical way to do is to take a value, hash it, take the output, hash it again and so forth for a fixed amount of iterations. You can try something like 1,000 or 10,000 iterations for example. This will make it that many times times slower for the attacker to find each password.

I think you should convert to utf8

--set utf8 for connection
SET collation_connection = 'utf8_general_ci'
--change CHARACTER SET of DB to utf8
ALTER DATABASE dbName CHARACTER SET utf8 COLLATE utf8_general_ci
--change CHARACTER SET of table to utf8
ALTER TABLE tableName CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci

You can delete any QuerySet you'd like. For example, to delete all blog posts with some Post model

Post.objects.all().delete()

and to delete any Post with a future publication date

Post.objects.filter(pub_date__gt=datetime.now()).delete()

You do, however, need to come up with a way to narrow down your QuerySet. If you just want a view to delete a particular object, look into the delete generic view.

EDIT:

Sorry for the misunderstanding. I think the answer is somewhere between. To implement your own, combine ModelForms and generic views. Otherwise, look into 3rd party apps that provide similar functionality. In a related question, the recommendation was django-filter.

You could open the SLN file in any text editor (Notepad, etc.) and simply change the project path there.

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

There is a much better way to handle this issue. Rather than removing Hyper-V altogether, you just make alternate boot to temporarily disable it when you need to use VMWare. As shown here...

http://www.hanselman.com/blog/SwitchEasilyBetweenVirtualBoxAndHyperVWithABCDEditBootEntryInWindows81.aspx

C:\>bcdedit /copy {current} /d "No Hyper-V" 
The entry was successfully copied to {ff-23-113-824e-5c5144ea}. 

C:\>bcdedit /set {ff-23-113-824e-5c5144ea} hypervisorlaunchtype off 
The operation completed successfully.

note: The ID generated from the first command is what you use in the second one. Don't just run it verbatim.

When you restart, you'll then just see a menu with two options...

• Windows 10
• No Hyper-V

So using VMWare is then just a matter of rebooting and choosing the No Hyper-V option.

If you want to remove a boot entry again. You can use the /delete option for bcdedit.

First, get a list of the current boot entries...

C:\>bcdedit /v

This lists all of the entries with their ID's. Copy the relevant ID, and then remove it like so...

C:\>bcdedit /delete {ff-23-113-824e-5c5144ea}

As mentioned in the comments, you need to do this from an elevated command prompt, not powershell. In powershell the command will error.

update: It is possible to run these commands in powershell, if the curly braces are escaped with backtick (`). Like so...

C:\WINDOWS\system32> bcdedit /copy `{current`} /d "No Hyper-V"

Here's a solution that gives you a list of all executables and aliases. It's also portable to systems without xargs -d (e.g. Mac OS X), and properly handles paths with spaces in them.

#!/bin/bash
(echo -n $PATH | tr : '\0' | xargs -0 -n 1 ls; alias | sed 's/alias \([^=]*\)=.*/\1/') | sort -u | grep "$@"

Usage: myscript.sh [grep-options] pattern, e.g. to find all commands that begin with ls, case-insensitive, do:

myscript -i ^ls

if you know for sure that there are only going to be 2 places where you have a list of digits in your string and that is the only thing you are going to pull out then you should be able to simply use

\d+

You could use the xpath :

//div[@class="measure-tab" and .//span[contains(., "someText")]]

Input :

<root>
<div class="measure-tab">
  <td> someText</td>
</div>
<div class="measure-tab">
  <div>
    <div2>
       <span>someText2</span>
   </div2>
  </div>
</div>
</root>

Output :

    Element='<div class="measure-tab">
  <div>
    <div2>
      <span>someText2</span>
    </div2>
  </div>
</div>'

Try this out:

$url = 'http://techcrunch.com/startups/'; $url = str_replace(array('http://', 'https://'), '', $url); 

EDIT:

Or, a simple way to always remove the protocol:

$url = 'https://www.google.com/'; $url = preg_replace('@^.+?\:\/\/@', '', $url); 

There is an important bit that is not mentioned in the article to which you linked and that is flex-basis. By default flex-basis is auto.

From the spec:

If the specified flex-basis is auto, the used flex basis is the value of the flex item’s main size property. (This can itself be the keyword auto, which sizes the flex item based on its contents.)

Each flex item has a flex-basis which is sort of like its initial size. Then from there, any remaining free space is distributed proportionally (based on flex-grow) among the items. With auto, that basis is the contents size (or defined size with width, etc.). As a result, items with bigger text within are being given more space overall in your example.

If you want your elements to be completely even, you can set flex-basis: 0. This will set the flex basis to 0 and then any remaining space (which will be all space since all basises are 0) will be proportionally distributed based on flex-grow.

li {
    flex-grow: 1;
    flex-basis: 0;
    /* ... */
}

This diagram from the spec does a pretty good job of illustrating the point.

And here is a working example with your fiddle.

I think that the RoundingMode you are looking for is ROUND_HALF_EVEN. From the javadoc:

Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor. Behaves as for ROUND_HALF_UP if the digit to the left of the discarded fraction is odd; behaves as for ROUND_HALF_DOWN if it's even. Note that this is the rounding mode that minimizes cumulative error when applied repeatedly over a sequence of calculations.

Here is a quick test case:

BigDecimal a = new BigDecimal("10.12345");
BigDecimal b = new BigDecimal("10.12556");

a = a.setScale(2, BigDecimal.ROUND_HALF_EVEN);
b = b.setScale(2, BigDecimal.ROUND_HALF_EVEN);

System.out.println(a);
System.out.println(b);

Correctly prints:

10.12
10.13

UPDATE:

setScale(int, int) has not been recommended since Java 1.5, when enums were first introduced, and was finally deprecated in Java 9. You should now use setScale(int, RoundingMode) e.g:

setScale(2, RoundingMode.HALF_EVEN)

2. Give Full privilege to the User.

3. Connect to the Server using PHP Code (Sample Given Below)

$link = mysql_connect('your_my_sql_servername or IP Address', 'new_user_which_u_created', 'password');
if (!$link) {
    die('Could not connect: ' . mysql_error());
}

echo 'Connected successfully';

mysql_select_db('sandsbtob',$link) or die ("could not open db".mysql_error());
// we connect to localhost at port 3306

In Python 3.4 pathlib was introduced:

>>> from pathlib import Path
>>> p = Path('/etc/usr/lib')
>>> p
PosixPath('/etc/usr/lib')
>>> p.parent
PosixPath('/etc/usr')

It also comes with many other helpful features e.g. for joining paths using slashes or easily walking the directory tree.

For more information refer to the docs or this blog post, which covers the differences between os.path and pathlib.

This is not directly related to the initial issue, but probably will help somebody.

I faced same issue when was trying to send similar request using domain account. So mine issue was in not escaped character in login name.

Bad example:

'ABC\username'

Good example:

'ABC\\username'

There are differences with some exceptions, e.g. KeyboardInterrupt.

Reading PEP8:

A bare except: clause will catch SystemExit and KeyboardInterrupt exceptions, making it harder to interrupt a program with Control-C, and can disguise other problems. If you want to catch all exceptions that signal program errors, use except Exception: (bare except is equivalent to except BaseException:).

It sounds to me as if you actually mean "linux guests" and not "linux hosts".

But in any case, I suspect you did not install the VMWare Tools: doubleclick on that icon on the Desktop that can be seen on your screenshot. It will install some drivers that communicate with VMWare that, among other things, allow to adjust the screen resolution dynamically.

When the installation process is finished, you'll most likely have to reboot the VM.

Someone has published a docker container / file for this:

https://github.com/vipul-sharma20/docker-opencv3-python3

https://hub.docker.com/r/vipul20/docker-opencv3-python3/~/dockerfile/

You can pull the image directly from docker hub or follow the instructions in the Dockerfile to install.

You can use ng-repeat with option like this:

<form>
    <select ng-model="yourSelect" 
        ng-options="option as option for option in ['var1', 'var2', 'var3']"
        ng-init="yourSelect='var1'"></select>
    <input type="hidden" name="yourSelect" value="{{yourSelect}}" />
</form>

When you submit your form you can get value of input hidden.

DEMO

ng-selected ng-repeat

Another alternative is Guava which has an easy-to-use suite of Hashing utilities. For example, to hash a string using SHA256 as a hex-string you would simply do:

final String hashed = Hashing.sha256()
        .hashString("your input", StandardCharsets.UTF_8)
        .toString();

Browsers and OS's determine the style of the select boxes in most cases, and it's next to impossible to alter them with CSS alone. You'll have to look into replacement methods. The main trick is to apply appearance: none which lets you override some of the styling.

My favourite method is this one:

http://cssdeck.com/item/265/styling-select-box-with-css3

It doesn't replace the OS select menu UI element so all the problems related to doing that are non-existant (not being able to break out of the browser window with a long list being the main one).

Good luck :)

We have 2 ways by which we can rename a file on AWS S3 storage -

1 .Using the CLI tool -

aws s3 --recursive mv s3://bucket-name/dirname/oldfile s3://bucket-name/dirname/newfile

2.Using SDK

$s3->copyObject(array(
'Bucket'     => $targetBucket,
'Key'        => $targetKeyname,
'CopySource' => "{$sourceBucket}/{$sourceKeyname}",));

By default, Elasticsearch will re-assign shards to nodes dynamically. However, if you've disabled shard allocation (perhaps you did a rolling restart and forgot to re-enable it), you can re-enable shard allocation.

# v0.90.x and earlier
curl -XPUT 'localhost:9200/_settings' -d '{
    "index.routing.allocation.disable_allocation": false
}'

# v1.0+
curl -XPUT 'localhost:9200/_cluster/settings' -d '{
    "transient" : {
        "cluster.routing.allocation.enable" : "all"
    }
}'

Elasticsearch will then reassign shards as normal. This can be slow, consider raising indices.recovery.max_bytes_per_sec and cluster.routing.allocation.node_concurrent_recoveries to speed it up.

If you're still seeing issues, something else is probably wrong, so look in your Elasticsearch logs for errors. If you see EsRejectedExecutionException your thread pools may be too small.

Finally, you can explicitly reassign a shard to a node with the reroute API.

# Suppose shard 4 of index "my-index" is unassigned, so you want to
# assign it to node search03:
curl -XPOST 'localhost:9200/_cluster/reroute' -d '{
    "commands": [{
        "allocate": {
            "index": "my-index",
            "shard": 4,
            "node": "search03",
            "allow_primary": 1
        }
    }]
}'

I use a slightly modified version of kolbyjack's second approach with ~ instead of ~*.

location ~ ^/service/ {
  proxy_pass http://apache/$uri$is_args$args;
}

Adapting Ijaz Ahmad Khan's answer to only yield lines when they are completely written (lines end with a newline char) gives a pythonic solution with no external dependencies:

def follow(file) -> Iterator[str]:
    """ Yield each line from a file as they are written. """
    line = ''
    while True:
        tmp = file.readline()
        if tmp is not None:
            line += tmp
            if line.endswith("\n"):
                yield line
                line = ''
        else:
            time.sleep(0.1)


if __name__ == '__main__':
    for line in follow(open("test.txt", 'r')):
        print(line, end='')

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

Will do the job as Buttle Butkus suggested.

go to files-> preference-> settings-> and search pylint and we got some few options and uncheck the option 'whether to lint python files' from 'python Linting:Enabled'.

If you found the variant of your preference you can also wrap it into a function.

Here I'm wrapping some bashism into a div function:

One liner:

function div { local _d=${3:-2}; local _n=0000000000; _n=${_n:0:$_d}; local _r=$(($1$_n/$2)); _r=${_r:0:-$_d}.${_r: -$_d}; echo $_r;}

Or multi line:

function div {
  local _d=${3:-2}
  local _n=0000000000
  _n=${_n:0:$_d}
  local _r=$(($1$_n/$2))
  _r=${_r:0:-$_d}.${_r: -$_d}
  echo $_r
}

Now you have the function

div <dividend> <divisor> [<precision=2>]

and use it like

> div 1 2
.50

> div 273 123 5
2.21951

> x=$(div 22 7)
> echo $x
3.14

UPDATE I added a little script which provides you the basic operations with floating point numbers for bash:

Usage:

> add 1.2 3.45
4.65
> sub 1000 .007
999.993
> mul 1.1 7.07
7.7770
> div 10 3
3.
> div 10 3.000
3.333

And here the script:

#!/bin/bash
__op() {
        local z=00000000000000000000000000000000
        local a1=${1%.*}
        local x1=${1//./}
        local n1=$((${#x1}-${#a1}))
        local a2=${2%.*}
        local x2=${2//./}
        local n2=$((${#x2}-${#a2}))
        local n=$n1
        if (($n1 < $n2)); then
                local n=$n2
                x1=$x1${z:0:$(($n2-$n1))}
        fi
        if (($n1 > $n2)); then
                x2=$x2${z:0:$(($n1-$n2))}
        fi
        if [ "$3" == "/" ]; then
                x1=$x1${z:0:$n}
        fi
        local r=$(($x1"$3"$x2))
        local l=$((${#r}-$n))
        if [ "$3" == "*" ]; then
                l=$(($l-$n))
        fi
        echo ${r:0:$l}.${r:$l}
}
add() { __op $1 $2 + ;}
sub() { __op $1 $2 - ;}
mul() { __op $1 $2 "*" ;}
div() { __op $1 $2 / ;}

After several days of searching found the EAN API - http://developer.ean.com/ - it is a very big one, but it provides really good information. Free demos, XML\JSON format. Looks good.

The Static variables are come into play once the program execution starts and it remain available till the program execution ends.

The Static variables are created in the Data Segment of the Memory.

You can create a dict and pass this as the data param to the dataframe constructor:

In [235]:

df = pd.DataFrame({'Gene':s.index, 'count':s.values})
df
Out[235]:
   Gene  count
0  Ezh2      2
1  Hmgb      7
2  Irf1      1

Alternatively you can create a df from the series, you need to call reset_index as the index will be used and then rename the columns:

In [237]:

df = pd.DataFrame(s).reset_index()
df.columns = ['Gene', 'count']
df
Out[237]:
   Gene  count
0  Ezh2      2
1  Hmgb      7
2  Irf1      1

Use the isin method:

rpt[rpt['STK_ID'].isin(stk_list)]

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

What you're doing is a static include. A static include is resolved at compile time, and may thus not use a parameter value, which is only known at execution time.

What you need is a dynamic include:

<jsp:include page="..." />

Note that you should use the JSP EL rather than scriptlets. It also seems that you're implementing a central controller with index.jsp. You should use a servlet to do that instead, and dispatch to the appropriate JSP from this servlet. Or better, use an existing MVC framework like Stripes or Spring MVC.

You will have to modify the below line:

<li><a href="#" data-toggle="modal" data-target="modalRegister">Register</a></li>

modalRegister is the ID and hence requires a preceding # for ID reference in html.

So, the modified html code snippet would be as follows:

<li><a href="#" data-toggle="modal" data-target="#modalRegister">Register</a></li>

Unfortunately the performance of getScaledInstance() is very poor if not problematic.

The alternative approach is to create a new BufferedImage and and draw a scaled version of the original on the new one.

BufferedImage resized = new BufferedImage(newWidth, newHeight, original.getType());
Graphics2D g = resized.createGraphics();
g.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
    RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g.drawImage(original, 0, 0, newWidth, newHeight, 0, 0, original.getWidth(),
    original.getHeight(), null);
g.dispose();

newWidth,newHeight indicate the new BufferedImage size and have to be properly calculated. In case of factor scaling:

int newWidth = new Double(original.getWidth() * widthFactor).intValue();
int newHeight = new Double(original.getHeight() * heightFactor).intValue();

EDIT: Found the article illustrating the performance issue: The Perils of Image.getScaledInstance()

Remember to run "android update avd -n avd_name" after change in Android SDK path.

just try to use cut -c startIndx-stopIndx

As other mentioned JSX is not a standard Javascript extension. It's better to name your entry point of Application based on .js and for the rest components, you can use .jsx.

I have an important reason for why I'm using .JSX for all component's file names. Actually, In a large scale project with huge bunch of code, if we set all React's component with .jsx extension, It'll be easier while navigating to different javascript files across the project(like helpers, middleware, etc.) and you know this is a React Component and not other types of the javascript file.

In a simple manner you can use rel="preload" instead of rel="stylesheet" .

<link rel="preload" href="path/to/mystylesheet.css" as="style" onload="this.rel='stylesheet'">

It's usually just easier to skip the mouse altogether--or it would be if Sublime didn't mess up multiselect when word wrapping. Here's the official documentation on using the keyboard and mouse for multiple selection. Since it's a bit spread out, I'll summarize it:

Where shortcuts are different in Sublime Text 3, I've made a note. For v3, I always test using the latest dev build; if you're using the beta build, your experience may be different.

If you lose your selection when switching tabs or windows (particularly on Linux), try using Ctrl + U to restore it.

Mouse

Windows/Linux

Building blocks:

• Positive/negative:
  • Add to selection: Ctrl
  • Subtract from selection: Alt In early builds of v3, this didn't work for linear selection.
• Selection type:
  • Linear selection: Left Click
  • Block selection: Middle Click or Shift + Right Click On Linux, middle click pastes instead by default.

Combine as you see fit. For example:

• Add to selection: Ctrl + Left Click (and optionally drag)
• Subtract from selection: Alt + Left Click This didn't work in early builds of v3.
• Add block selection: Ctrl + Shift + Right Click (and drag)
• Subtract block selection: Alt + Shift + Right Click (and drag)

Mac OS X

Building blocks:

• Positive/negative:
  • Add to selection: ?
  • Subtract from selection: ?? (only works with block selection in v3; presumably bug)
• Selection type:
  • Linear selection: Left Click
  • Block selection: Middle Click or ? + Left Click

Combine as you see fit. For example:

• Add to selection: ? + Left Click (and optionally drag)
• Subtract from selection: ?? + Left Click (and drag--this combination doesn't work in Sublime Text 3, but supposedly it works in 2)
• Add block selection: ?? + Left Click (and drag)
• Subtract block selection: ??? + Left Click (and drag)

Keyboard

Windows

• Return to single selection mode: Esc
• Extend selection upward/downward at all carets: Ctrl + Alt + Up/Down
• Extend selection leftward/rightward at all carets: Shift + Left/Right
• Move all carets up/down/left/right, and clear selection: Up/Down/Left/Right
• Undo the last selection motion: Ctrl + U
• Add next occurrence of selected text to selection: Ctrl + D
• Add all occurrences of the selected text to the selection: Alt + F3
• Rotate between occurrences of selected text (single selection): Ctrl + F3 (reverse: Ctrl + Shift + F3)
• Turn a single linear selection into a block selection, with a caret at the end of the selected text in each line: Ctrl + Shift + L

Linux

• Return to single selection mode: Esc
• Extend selection upward/downward at all carets: Alt + Up/Down Note that you may be able to hold Ctrl as well to get the same shortcuts as Windows, but Linux tends to use Ctrl + Alt combinations for global shortcuts.
• Extend selection leftward/rightward at all carets: Shift + Left/Right
• Move all carets up/down/left/right, and clear selection: Up/Down/Left/Right
• Undo the last selection motion: Ctrl + U
• Add next occurrence of selected text to selection: Ctrl + D
• Add all occurrences of the selected text to the selection: Alt + F3
• Rotate between occurrences of selected text (single selection): Ctrl + F3 (reverse: Ctrl + Shift + F3)
• Turn a single linear selection into a block selection, with a caret at the end of the selected text in each line: Ctrl + Shift + L

Mac OS X

• Return to single selection mode: ? (that's the Mac symbol for Escape)
• Extend selection upward/downward at all carets: ^??, ^?? (See note)
• Extend selection leftward/rightward at all carets: ??/??
• Move all carets up/down/left/right and clear selection: ?, ?, ?, ?
• Undo the last selection motion: ?U
• Add next occurrence of selected text to selection: ?D
• Add all occurrences of the selected text to the selection: ^?G
• Rotate between occurrences of selected text (single selection): ??G (reverse: ???G)
• Turn a single linear selection into a block selection, with a caret at the end of the selected text in each line: ??L

Notes for Mac users

On Yosemite and El Capitan, ^?? and ^?? are system keyboard shortcuts by default. If you want them to work in Sublime Text, you will need to change them:

1. Open System Preferences.
2. Select the Shortcuts tab.
3. Select Mission Control in the left listbox.
4. Change the keyboard shortcuts for Mission Control and Application windows (or disable them). I use ^?? and ^??. They defaults are ^? and ^?; adding ^ to those shortcuts triggers the same actions, but slows the animations.

In case you're not familiar with Mac's keyboard symbols:

• ? is the escape key
• ^ is the control key
• ? is the option key
• ? is the shift key
• ? is the command key
• ? et al are the arrow keys, as depicted

Dim SourcePath As String = "c:\SomeFolder\SomeFileYouWantToCopy.txt" 'This is just an example string and could be anything, it maps to fileToCopy in your code.
Dim SaveDirectory As string = "c:\DestinationFolder"

Dim Filename As String = System.IO.Path.GetFileName(SourcePath) 'get the filename of the original file without the directory on it
Dim SavePath As String = System.IO.Path.Combine(SaveDirectory, Filename) 'combines the saveDirectory and the filename to get a fully qualified path.

If System.IO.File.Exists(SavePath) Then
   'The file exists
Else
    'the file doesn't exist
End If

If you need to convert a string to a DateTime you could try

DateTime dt = DateTime.Parse("01:00 PM"); // No error checking

or (with error checking)

DateTime dt;
bool res = DateTime.TryParse("01:00 PM", out dt);

Variable dt contains your datetime, so you can write it

dt.ToString("HH:mm");

Last one works for every DateTime var you have, so if you still have a DateTime, you can write it out in this way.

If there is a failed merge, which is the most common reason for wanting to undo a git pull, running git reset --merge does exactly what one would expect: keep the fetched files, but undo the merge that git pull attempted to merge. Then one can decide what to do without the clutter that git merge sometimes generates. And it does not need one to find the exact commit ID which --hard mentioned in every other answer requires.

I believe if you used the double data type, the re-calculation in Excel would work just fine.

mapper.enable(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT);

My code work well just as the answer above. The reason is that the json from jackson is different with the json sent from controller.

String test1= mapper.writeValueAsString(result1);

And the json is like(which can be deserialized normally):

{"code":200,"message":"god","data":[{"nics":null,"status":null,"desktopOperatorType":null,"marker":null,"user_name":null,"user_group":null,"user_email":null,"product_id":null,"image_id":null,"computer_name":"AAAA","desktop_id":null,"created":null,"ip_address":null,"security_groups":null,"root_volume":null,"data_volumes":null,"availability_zone":null,"ou_name":null,"login_status":null,"desktop_ip":null,"ad_id":null},{"nics":null,"status":null,"desktopOperatorType":null,"marker":null,"user_name":null,"user_group":null,"user_email":null,"product_id":null,"image_id":null,"computer_name":"BBBB","desktop_id":null,"created":null,"ip_address":null,"security_groups":null,"root_volume":null,"data_volumes":null,"availability_zone":null,"ou_name":null,"login_status":null,"desktop_ip":null,"ad_id":null}]}

but the json send from the another service just like:

{"code":200,"message":"????????","data":[{"nics":"","status":"","metadata":"","desktopOperatorType":"","marker":"","user_name":"csrgzbsjy","user_group":"ADMINISTRATORS","user_email":"","product_id":"","image_id":"","computer_name":"B-jiegou-all-15","desktop_id":"6360ee29-eb82-416b-aab8-18ded887e8ff","created":"2018-11-12T07:45:15.000Z","ip_address":"192.168.2.215","security_groups":"","root_volume":"","data_volumes":"","availability_zone":"","ou_name":"","login_status":"","desktop_ip":"","ad_id":""},{"nics":"","status":"","metadata":"","desktopOperatorType":"","marker":"","user_name":"glory_2147","user_group":"ADMINISTRATORS","user_email":"","product_id":"","image_id":"","computer_name":"H-pkpm-all-357","desktop_id":"709164e4-d3e6-495d-9c1e-a7b82e30bc83","created":"2018-11-09T09:54:09.000Z","ip_address":"192.168.2.235","security_groups":"","root_volume":"","data_volumes":"","availability_zone":"","ou_name":"","login_status":"","desktop_ip":"","ad_id":""}]}

You can notice the difference when dealing with the param without initiation. Be careful

I wish the error message would output the problem string. I was getting this due to a weird copy and paste problem of a "docker run" command. A space-like character was being used before the repo and image name.

I was getting this error today and couldn't work it out for a while, but I realised it was after adding some RequireAttributes to my models and that some development seed data was not populating all of the required fields.
So just a note that if you're getting this error whilst updating the database through some sort of init strategy like DropCreateDatabaseIfModelChanges then you have to make sure that your seed data fulfils and satisfies any model data validation attributes.

I know this is slightly different to the problem in the question, but it's a popular question so I thought I'd add a bit more to the answer for others having the same issue as myself.
Hope this helps others :)

Warning create_function() has been DEPRECATED as of PHP 7.2.0. Relying on this function is highly discouraged.

Builtin loops in PHP are faster then interpreted loops, so it actually makes sense to make this one a one-liner:

$result = array();
array_walk($cats, create_function('$value, $key, &$result', '$result[] = $value->id;'), $result)

I use the following function to post data using curl. $data is an array of fields to post (will be correctly encoded using http_build_query). The data is encoded using application/x-www-form-urlencoded.

function httpPost($url, $data)
{
    $curl = curl_init($url);
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    $response = curl_exec($curl);
    curl_close($curl);
    return $response;
}

@Edward mentions that http_build_query may be omitted since curl will correctly encode array passed to CURLOPT_POSTFIELDS parameter, but be advised that in this case the data will be encoded using multipart/form-data.

I use this function with APIs that expect data to be encoded using application/x-www-form-urlencoded. That's why I use http_build_query().

Based on the the source code of setTextSize:

public void setTextSize(int unit, float size) {
    Context c = getContext();
    Resources r;

    if (c == null)
        r = Resources.getSystem();
    else
        r = c.getResources();

    setRawTextSize(TypedValue.applyDimension(
        unit, size, r.getDisplayMetrics()));
}

I build this function for calulating any demension to pixels:

int getPixels(int unit, float size) {
    DisplayMetrics metrics = Resources.getSystem().getDisplayMetrics();
    return (int)TypedValue.applyDimension(unit, size, metrics);
}

Where unit is something like TypedValue.COMPLEX_UNIT_SP.

The rvest along with xml2 is another popular package for parsing html web pages.

library(rvest)
theurl <- "http://en.wikipedia.org/wiki/Brazil_national_football_team"
file<-read_html(theurl)
tables<-html_nodes(file, "table")
table1 <- html_table(tables[4], fill = TRUE)

The syntax is easier to use than the xml package and for most web pages the package provides all of the options ones needs.

If you want your program to crash and not know the reason, then go ahead and trust the programmers and c basic error handling.

I think it's best to build in some kind of error reporting, call it debug mode, turn it off when your want best performance and turn it on when you want to debug a issue. Hopefully you can hit it again.

There will be bugs, the question is how do you want to spend your days and nights looking for them.

Example:

['Thanks You',
 'Its fine no problem',
 'Are you sure']

code block:

import pandas as pd
df = pd.DataFrame(lst)

Output:

    0
0   Thanks You
1   Its fine no problem
2   Are you sure

It is not recommended to remove the column names of the panda dataframe. but if you still want your data frame without header(as per the format you posted in the question) you can do this:

df = pd.DataFrame(lst)    
df.columns = ['']

Output will be like this:

0   Thanks You
1   Its fine no problem
2   Are you sure

or

df = pd.DataFrame(lst).to_string(header=False)

But the output will be a list instead of a dataframe:

0           Thanks You
1  Its fine no problem
2         Are you sure

Hope this helps!!

I put this in my ~/.gitconfig:

[alias]
    find = log --pretty=\"format:%Cgreen%H %Cblue%s\" --name-status --grep

Then I can type "git find string" and I get a list of all the commits containing that string in the message. For example, to find all commits referencing ticket #33:

Had the same problem, while differently from other answers in my case I use ASP.NET to develop the WebAPI server.

I already had Corps allowed and it worked for GET requests. To make POST requests work I needed to add 'AllowAnyHeader()' and 'AllowAnyMethod()' options to the list of Corp options.

Here are essential parts of related functions in Start class look like:

                          {
                              builder
                                  .WithOrigins("http://localhost:4200")
                                  .AllowAnyHeader()
                                  .AllowAnyMethod()
                                  //.AllowCredentials()
                                  ;
                          });
    });

Configure method:

        app.UseCors(MyAllowSpecificOrigins);

Check which one the system is currently using:

python --version

Add the main folder location (e.g. C/ProgramFiles) and Scripts location (C/ProgramFiles/Scripts) to Environment Variables of the system. Add both 3.x version and 2.x version

Path location is ranked inside environment variable. If you want to use Python 2.x simply put path of python 2.x first, if you want for Python 3.x simply put 3.x first

This uses python 2

An alternative approach may be to embed images in the email using the cid method. (Basically including the image as an attachment, and then embedding it). In my experience, this approach seems to be well supported these days.

-----> pip install gensim config --global http.sslVerify false

Just install any package with the "config --global http.sslVerify false" statement

You can ignore SSL errors by setting pypi.org and files.pythonhosted.org as trusted hosts.

$ pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org <package_name>

Note: Sometime during April 2018, the Python Package Index was migrated from pypi.python.org to pypi.org. This means "trusted-host" commands using the old domain no longer work.

Permanent Fix

Since the release of pip 10.0, you should be able to fix this permanently just by upgrading pip itself:

$ pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org pip setuptools

Or by just reinstalling it to get the latest version:

$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

(… and then running get-pip.py with the relevant Python interpreter).

pip install <otherpackage> should just work after this. If not, then you will need to do more, as explained below.

You may want to add the trusted hosts and proxy to your config file.

pip.ini (Windows) or pip.conf (unix)

[global]
trusted-host = pypi.python.org
               pypi.org
               files.pythonhosted.org

Alternate Solutions (Less secure)

Most of the answers could pose a security issue.

Two of the workarounds that help in installing most of the python packages with ease would be:

• Using easy_install: if you are really lazy and don't want to waste much time, use easy_install <package_name>. Note that some packages won't be found or will give small errors.
• Using Wheel: download the Wheel of the python package and use the pip command pip install wheel_package_name.whl to install the package.

As mentioned by sombody above, restarting eclipse worked for me for the user defined environment variable. After I restart eclipse IDE, System.getenv() is picking up my environment variable.

I needed to measure the execution time of individual functions within a library. I didn't want to have to wrap every call of every function with a time measuring function because its ugly and deepens the call stack. I also didn't want to put timer code at the top and bottom of every function because it makes a mess when the function can exit early or throw exceptions for example. So what I ended up doing was making a timer that uses its own lifetime to measure time.

In this way I can measure the wall-time a block of code took by just instantiating one of these objects at the beginning of the code block in question (function or any scope really) and then allowing the instances destructor to measure the time elapsed since construction when the instance goes out of scope. You can find the full example here but the struct is extremely simple:

template <typename clock_t = std::chrono::steady_clock>
struct scoped_timer {
  using duration_t = typename clock_t::duration;
  const std::function<void(const duration_t&)> callback;
  const std::chrono::time_point<clock_t> start;

  scoped_timer(const std::function<void(const duration_t&)>& finished_callback) :
      callback(finished_callback), start(clock_t::now()) { }
  scoped_timer(std::function<void(const duration_t&)>&& finished_callback) :
      callback(finished_callback), start(clock_t::now()) { }
  ~scoped_timer() { callback(clock_t::now() - start); }
};

The struct will call you back on the provided functor when it goes out of scope so you can do something with the timing information (print it or store it or whatever). If you need to do something even more complex you could even use std::bind with std::placeholders to callback functions with more arguments.

Here's a quick example of using it:

void test(bool should_throw) {
  scoped_timer<> t([](const scoped_timer<>::duration_t& elapsed) {
    auto e = std::chrono::duration_cast<std::chrono::duration<double, std::milli>>(elapsed).count();
    std::cout << "took " << e << "ms" << std::endl;
  });

  std::this_thread::sleep_for(std::chrono::seconds(1));

  if (should_throw)
    throw nullptr;

  std::this_thread::sleep_for(std::chrono::seconds(1));
}

If you want to be more deliberate, you can also use new and delete to explicitly start and stop the timer without relying on scoping to do it for you.

There are several ways rsync compares files -- the authoritative source is the rsync algorithm description: https://www.andrew.cmu.edu/course/15-749/READINGS/required/cas/tridgell96.pdf. The wikipedia article on rsync is also very good.

For local files, rsync compares metadata and if it looks like it doesn't need to copy the file because size and timestamp match between source and destination it doesn't look further. If they don't match, it cp's the file. However, what if the metadata do match but files aren't actually the same? Then rsync probably didn't do what you intended.

Files that are the same size may still have changed. One simple example is a text file where you correct a typo -- like changing "teh" to "the". The file size is the same, but the corrected file will have a newer timestamp. --size-only says "don't look at the time; if size matches assume files match", which would be the wrong choice in this case.

On the other hand, suppose you accidentally did a big cp -r A B yesterday, but you forgot to preserve the time stamps, and now you want to do the operation in reverse rsync B A. All those files you cp'ed have yesterday's time stamp, even though they weren't really modified yesterday, and rsync will by default end up copying all those files, and updating the timestamp to yesterday too. --size-only may be your friend in this case (modulo the example above).

--ignore-times says to compare the files regardless of whether the files have the same modify time. Consider the typo example above, but then not only did you correct the typo but you used touch to make the corrected file have the same modify time as the original file -- let's just say you're sneaky that way. Well --ignore-times will do a diff of the files even though the size and time match.

Try the following snippet:

var mystring = 'this,is,an,example';
var splits = mystring.split(",");
alert(splits[0]); // output: this

You have to loop through the array and printf() each element:

for(int i=0;i<10;++i) {
  printf("%.2f ", foo[i]);
}

printf("\n");

# prevent mime based attacks
Header set X-Content-Type-Options "nosniff"

This header prevents "mime" based attacks. This header prevents Internet Explorer from MIME-sniffing a response away from the declared content-type as the header instructs the browser not to override the response content type. With the nosniff option, if the server says the content is text/html, the browser will render it as text/html.

Key points which explain difference and provide guidance upon working with unittest.mock

1. Use Mock if you want to replace some interface elements(passing args) of the object under test
2. Use patch if you want to replace internal call to some objects and imported modules of the object under test
3. Always provide spec from the object you are mocking
   • With patch you can always provide autospec
   • With Mock you can provide spec
   • Instead of Mock, you can use create_autospec, which intended to create Mock objects with specification.

In the question above the right answer would be to use Mock, or to be more precise create_autospec (because it will add spec to the mock methods of the class you are mocking), the defined spec on the mock will be helpful in case of an attempt to call method of the class which doesn't exists ( regardless signature), please see some

from unittest import TestCase
from unittest.mock import Mock, create_autospec, patch


class MyClass:
    
    @staticmethod
    def method(foo, bar):
        print(foo)


def something(some_class: MyClass):
    arg = 1
    # Would fail becuase of wrong parameters passed to methd.
    return some_class.method(arg)


def second(some_class: MyClass):
    arg = 1
    return some_class.unexisted_method(arg)


class TestSomethingTestCase(TestCase):
    def test_something_with_autospec(self):
        mock = create_autospec(MyClass)
        mock.method.return_value = True
        # Fails because of signature misuse.
        result = something(mock)
        self.assertTrue(result)
        self.assertTrue(mock.method.called)
    
    def test_something(self):
        mock = Mock()  # Note that Mock(spec=MyClass) will also pass, because signatures of mock don't have spec.
        mock.method.return_value = True
        
        result = something(mock)
        
        self.assertTrue(result)
        self.assertTrue(mock.method.called)
        
    def test_second_with_patch_autospec(self):
        with patch(f'{__name__}.MyClass', autospec=True) as mock:
            # Fails because of signature misuse.
            result = second(mock)
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)


class TestSecondTestCase(TestCase):
    def test_second_with_autospec(self):
        mock = Mock(spec=MyClass)
        # Fails because of signature misuse.
        result = second(mock)
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)
    
    def test_second_with_patch_autospec(self):
        with patch(f'{__name__}.MyClass', autospec=True) as mock:
            # Fails because of signature misuse.
            result = second(mock)
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)
    
    def test_second(self):
        mock = Mock()
        mock.unexisted_method.return_value = True
        
        result = second(mock)
        
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)

The test cases with defined spec used fail because methods called from something and second functions aren't complaint with MyClass, which means - they catch bugs, whereas default Mock will display.

As a side note there is one more option: use patch.object to mock just the class method which is called with.

The good use cases for patch would be the case when the class is used as inner part of function:

def something():
    arg = 1
    return MyClass.method(arg)

Then you will want to use patch as a decorator to mock the MyClass.

If you need to write semantically correct mark-up, even in HTML5, you must not use ' to escape single quotes. Although, I can imagine you actually meant apostrophe rather then single quote.

single quotes and apostrophes are not the same, semantically, although they might look the same.

Here's one apostrophe.

Use ' to insert it if you need HTML4 support. (edited)

In British English, single quotes are used like this:

"He told me to 'give it a try'", I said.

Quotes come in pairs. You can use:

<p><q>He told me to <q>give it a try</q></q>, I said.<p>

to have nested quotes in a semantically correct way, deferring the substitution of the actual characters to the rendering engine. This substitution can then be affected by CSS rules, like:

q {
  quotes: '"' '"' '<' '>';
} 

An old but seemingly still relevant article about semantically correct mark-up: The Trouble With EM ’n EN (and Other Shady Characters).

(edited) This used to be:

Use ’ to insert it if you need HTML4 support.

But, as @James_pic pointed out, that is not the straight single quote, but the "Single curved quote, right".

the time signal is not built into network antennas: you have to use the NTP protocol in order to retrieve the time on a ntp server. there are plenty of ntp clients, available as standalone executables or libraries.

the gps signal does indeed include a precise time signal, which is available with any "fix".

however, if nor the network, nor the gps are available, your only choice is to resort on the time of the phone... your best solution would be to use a system wide setting to synchronize automatically the phone time to the gps or ntp time, then always use the time of the phone.

note that the phone time, if synchronized regularly, should not differ much from the gps or ntp time. also note that forcing a user to synchronize its time may be intrusive, you 'd better ask your user if he accepts synchronizing. at last, are you sure you absolutely need a time that precise ?

    DoStuffFunction();

    if (window.addEventListener) {

    } else {
        window.attachEvent('onload', DoStuffFunction);
    }
}

For understanding templates, it's of huge advantage to get the terminology straight because the way you speak about them determines the way to think about them.

Specifically, Area is not a template class, but a class template. That is, it is a template from which classes can be generated. Area<int> is such a class (it's not an object, but of course you can create an object from that class in the same ways you can create objects from any other class). Another such class would be Area<char>. Note that those are completely different classes, which have nothing in common except for the fact that they were generated from the same class template.

Since Area is not a class, you cannot derive the class Rectangle from it. You only can derive a class from another class (or several of them). Since Area<int> is a class, you could, for example, derive Rectangle from it:

class Rectangle:
  public Area<int>
{
  // ...
};

Since Area<int> and Area<char> are different classes, you can even derive from both at the same time (however when accessing members of them, you'll have to deal with ambiguities):

class Rectangle:
  public Area<int>,
  public Area<char>
{
  // ...
};

However you have to specify which classed to derive from when you define Rectangle. This is true no matter whether those classes are generated from a template or not. Two objects of the same class simply cannot have different inheritance hierarchies.

What you can do is to make Rectangle a template as well. If you write

template<typename T> class Rectangle:
  public Area<T>
{
  // ...
};

You have a template Rectangle from which you can get a class Rectangle<int> which derives from Area<int>, and a different class Rectangle<char> which derives from Area<char>.

It may be that you want to have a single type Rectangle so that you can pass all sorts of Rectangle to the same function (which itself doesn't need to know the Area type). Since the Rectangle<T> classes generated by instantiating the template Rectangle are formally independent of each other, it doesn't work that way. However you can make use of multiple inheritance here:

class Rectangle // not inheriting from any Area type
{
  // Area independent interface
};

template<typename T> class SpecificRectangle:
  public Rectangle,
  public Area<T>
{
  // Area dependent stuff
};

void foo(Rectangle&); // A function which works with generic rectangles

int main()
{
  SpecificRectangle<int> intrect;
  foo(intrect);

  SpecificRectangle<char> charrect;
  foo(charrect);
}

If it is important that your generic Rectangle is derived from a generic Area you can do the same trick with Area too:

class Area
{
  // generic Area interface
};

class Rectangle:
  public virtual Area // virtual because of "diamond inheritance"
{
  // generic rectangle interface
};

template<typename T> class SpecificArea:
  public virtual Area
{
  // specific implementation of Area for type T
};

template<typename T> class SpecificRectangle:
  public Rectangle, // maybe this should be virtual as well, in case the hierarchy is extended later
  public SpecificArea<T> // no virtual inheritance needed here
{
  // specific implementation of Rectangle for type T
};

I have resolved it by deleting android-support-v4.jar from my Project. Because appcompat_v7 already have a copy of it.

If you have already import appcompat_v7 but still the problem doesn't solve. then try it.

You can use a function like this to do the conversion:

function toDegrees (angle) {
  return angle * (180 / Math.PI);
}

Note that functions like sin, cos, and so on do not return angles, they take angles as input. It seems to me that it would be more useful to you to have a function that converts a degree input to radians, like this:

function toRadians (angle) {
  return angle * (Math.PI / 180);
}

which you could use to do something like tan(toRadians(45)).

I guess I'm pretty late to the party..

As previously stated, calling input.nextLine() after getting your int value will solve your problem. The reason why your code didn't work was because there was nothing else to store from your input (where you inputted the int) into string1. I'll just shed a little more light to the entire topic.

Consider nextLine() as the odd one out among the nextFoo() methods in the Scanner class. Let's take a quick example.. Let's say we have two lines of code like the ones below:

int firstNumber = input.nextInt();
int secondNumber = input.nextInt();

If we input the value below (as a single line of input)

54 234

The value of our firstNumber and secondNumber variable become 54 and 234 respectively. The reason why this works this way is because a new line feed (i.e \n) IS NOT automatically generated when the nextInt() method takes in the values. It simply takes the "next int" and moves on. This is the same for the rest of the nextFoo() methods except nextLine().

nextLine() generates a new line feed immediately after taking a value; this is what @RohitJain means by saying the new line feed is "consumed".

Lastly, the next() method simply takes the nearest String without generating a new line; this makes this the preferential method for taking separate Strings within the same single line.

I hope this helps.. Merry coding!

First off I recommend you use the following constructor instead of the one you currently use:

new SerialPort("COM10", 115200, Parity.None, 8, StopBits.One);

Next, you really should remove this code:

// Wait 10 Seconds for data...
for (int i = 0; i < 1000; i++)
{
    Thread.Sleep(10);
    Console.WriteLine(sp.Read(buf,0,bufSize)); //prints data directly to the Console
}

And instead just loop until the user presses a key or something, like so:

namespace serialPortCollection
{   class Program
    {
        static void Main(string[] args)
        {
            SerialPort sp = new SerialPort("COM10", 115200);
            sp.DataReceived += port_OnReceiveDatazz; // Add DataReceived Event Handler

            sp.Open();
            sp.WriteLine("$"); //Command to start Data Stream

            Console.ReadLine();

            sp.WriteLine("!"); //Stop Data Stream Command
            sp.Close();
        }

       // My Event Handler Method
        private static void port_OnReceiveDatazz(object sender, 
                                   SerialDataReceivedEventArgs e)
        {
            SerialPort spL = (SerialPort) sender;
            byte[] buf = new byte[spL.BytesToRead];
            Console.WriteLine("DATA RECEIVED!");
            spL.Read(buf, 0, buf.Length);
            foreach (Byte b in buf)
            {
                Console.Write(b.ToString());
            }
            Console.WriteLine();
        }
    }
}

Also, note the revisions to the data received event handler, it should actually print the buffer now.

UPDATE 1

I just ran the following code successfully on my machine (using a null modem cable between COM33 and COM34)

namespace TestApp
{
    class Program
    {
        static void Main(string[] args)
        {
            Thread writeThread = new Thread(new ThreadStart(WriteThread));
            SerialPort sp = new SerialPort("COM33", 115200, Parity.None, 8, StopBits.One);
            sp.DataReceived += port_OnReceiveDatazz; // Add DataReceived Event Handler

            sp.Open();
            sp.WriteLine("$"); //Command to start Data Stream

            writeThread.Start();

            Console.ReadLine();

            sp.WriteLine("!"); //Stop Data Stream Command
            sp.Close();
        }

        private static void port_OnReceiveDatazz(object sender, 
                                   SerialDataReceivedEventArgs e)
        {
            SerialPort spL = (SerialPort) sender;
            byte[] buf = new byte[spL.BytesToRead];
            Console.WriteLine("DATA RECEIVED!");
            spL.Read(buf, 0, buf.Length);
            foreach (Byte b in buf)
            {
                Console.Write(b.ToString() + " ");
            }
            Console.WriteLine();
        }

        private static void WriteThread()
        {
            SerialPort sp2 = new SerialPort("COM34", 115200, Parity.None, 8, StopBits.One);
            sp2.Open();
            byte[] buf = new byte[100];
            for (byte i = 0; i < 100; i++)
            {
                buf[i] = i;
            }
            sp2.Write(buf, 0, buf.Length);
            sp2.Close();
        }
    }
}

UPDATE 2

Given all of the traffic on this question recently. I'm beginning to suspect that either your serial port is not configured properly, or that the device is not responding.

I highly recommend you attempt to communicate with the device using some other means (I use hyperterminal frequently). You can then play around with all of these settings (bitrate, parity, data bits, stop bits, flow control) until you find the set that works. The documentation for the device should also specify these settings. Once I figured those out, I would make sure my .NET SerialPort is configured properly to use those settings.

Some tips on configuring the serial port:

Note that when I said you should use the following constructor, I meant that use that function, not necessarily those parameters! You should fill in the parameters for your device, the settings below are common, but may be different for your device.

new SerialPort("COM10", 115200, Parity.None, 8, StopBits.One);

It is also important that you setup the .NET SerialPort to use the same flow control as your device (as other people have stated earlier). You can find more info here:

http://www.lammertbies.nl/comm/info/RS-232_flow_control.html

Here is the simplest solution to your query

$date=date_create("2013-03-15"); // or your date string
date_add($date,date_interval_create_from_date_string("40 days"));// add number of days 
echo date_format($date,"Y-m-d"); //set date format of the result

Completely reset?

1. Delete the .git directory locally.

2. Recreate the git repostory:

   $ cd (project-directory)
   $ git init
   $ (add some files)
   $ git add .
   $ git commit -m 'Initial commit'
   

3. Push to remote server, overwriting. Remember you're going to mess everyone else up doing this … you better be the only client.

   $ git remote add origin <url>
   $ git push --force --set-upstream origin master
   

You can use this syntax to add an index and control the kind of index (HASH or BTREE).

create index your_index_name on your_table_name(your_column_name) using HASH;
or
create index your_index_name on your_table_name(your_column_name) using BTREE;

You can learn about differences between BTREE and HASH indexes here: http://dev.mysql.com/doc/refman/5.5/en/index-btree-hash.html

Use this:

TextView txt = (TextView) findViewById(R.id.Textview1);
txt.setPaintFlags(txt.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

All above answers are correct, but you loose configuration settings.

But if your IDE's only themes or fonts are changed or some UI related issues and you want to restore to default theme, then just delete

${user.home}/.IntelliJIdea13/config/options/options.xml

file while IDE is not running, then after next restart IDE's theme will gets reset to default.

You can find the list of formats here (in the Double.ToString()-MSDN-Article) as comments in the example section.

The easiest way in 2018 should be TextEncoder but the returned element is not byte array, it is Uint8Array. (And not all browsers support it)

let utf8Encode = new TextEncoder();
utf8Encode.encode("eee")
> Uint8Array [ 101, 101, 101 ]

From the PHP manual:

<?php
$row = 1;
if (($handle = fopen("test.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $num = count($data);
        echo "<p> $num fields in line $row: <br /></p>\n";
        $row++;
        for ($c=0; $c < $num; $c++) {
            echo $data[$c] . "<br />\n";
        }
    }
    fclose($handle);
}
?>

This answer has been very beautifully explained in book "Microservices Interview Questions, For Java Developers (Spring Boot, Spring Cloud, Cloud Native Applications) by Munish Chandel, Version 1.30, 25.03.2018.

The following content has been taken from this book, and total credit for this answer goes to the Author of the book i.e. Munish Chandel

application.yml

application.yml/application.properties file is specific to Spring Boot applications. Unless you change the location of external properties of an application, spring boot will always load application.yml from the following location:

/src/main/resources/application.yml

You can store all the external properties for your application in this file. Common properties that are available in any Spring Boot project can be found at: https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html You can customize these properties as per your application needs. Sample file is shown below:

spring:
    application:
        name: foobar
    datasource:
        driverClassName: com.mysql.jdbc.Driver
        url: jdbc:mysql://localhost/test
server:
    port: 9000

bootstrap.yml

bootstrap.yml on the other hand is specific to spring-cloud-config and is loaded before the application.yml

bootstrap.yml is only needed if you are using Spring Cloud and your microservice configuration is stored on a remote Spring Cloud Config Server.

Important points about bootstrap.yml

1. When used with Spring Cloud Config server, you shall specify the application-name and config git location using below properties.

spring.application.name: "application-name"
spring.cloud.config.server.git.uri: "git-uri-config"

2. When used with microservices (other than cloud config server), we need to specify the application name and location of config server using below properties

spring.application.name: 
spring.cloud.config.uri: 

3. This properties file can contain other configuration relevant to Spring Cloud environment for e.g. eureka server location, encryption/decryption related properties.

Upon startup, Spring Cloud makes an HTTP(S) call to the Spring Cloud Config Server with the name of the application and retrieves back that application’s configuration.

application.yml contains the default configuration for the microservice and any configuration retrieved (from cloud config server) during the bootstrap process will override configuration defined in application.yml

For writing iterative equivalents of these recursive methods, we can first understand how the recursive methods themselves execute over the program's stack. Assuming that the nodes do not have their parent pointer, we need to manage our own "stack" for the iterative variants.

One way to start is to see the recursive method and mark the locations where a call would "resume" (fresh initial call, or after a recursive call returns). Below these are marked as "RP 0", "RP 1" etc ("Resume Point"). For the case of postorder traversal:

void post(node *x)  
{  
  /* RP 0 */  
  if(x->lc) post(x->lc);  
  /* RP 1 */  
  if(x->rc) post(x->rc);  
  /* RP 2 */  
  process(x);  
}

Its iterative variant:

void post_i(node *root)  
{  
  node *stack[1000];  
  int top;  
  node *popped;  
 
  stack[0] = root;  
  top = 0;  
  popped = NULL;  
 
#define POPPED_A_CHILD() \  
  (popped && (popped == curr->lc || popped == curr->rc))  
 
  while(top >= 0)  
  {  
    node *curr = stack[top];  
 
    if(!POPPED_A_CHILD())  
    {  
      /* type (x: 0) */  
      if(curr->rc || curr->lc)  
      {  
        if(curr->rc) stack[++top] = curr->rc;  
 
        if(curr->lc) stack[++top] = curr->lc;  
 
        popped = NULL;  
        continue;  
      }  
    }  
 
    /* type (x: 2) */  
    process(curr);  
    top--;  
    popped = curr;  
  }  
}

The code comments with (x: 0) and (x: 2) correspond to the "RP 0" and "RP 2" resume points in the recursive method.

By pushing both the lc and rc pointers together, we have removed the need of keeping the post(x) invocation at resume-point 1 while the post(x->lc) completes its execution. That is, we could directly shift the node to "RP 2", bypassing "RP 1". So, there is no node kept on stack at "RP 1" stage.

The POPPED_A_CHILD macro helps us deduce one of the two resume-points ("RP 0", or "RP 2").

You can read in detail about this approach here (section "Postorder Traversal").

We can also set this in Global.asax file for Asp.net application.

protected void Application_BeginRequest(object sender, EventArgs e)
    {

    // enable CORS
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "https://www.youtube.com");

    }

SELECT a.salesorderid, a.orderdate, s.orderdate, s.salesorderid
FROM A a
OUTER APPLY (SELECT top(1) *
             FROM B b WHERE a.salesorderid = b.salesorderid) as s
WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'

Our git repo disk is mounted on AIX box to do BUILD.

It sounds like you mounted the drive on which the git repository is stored on another server, and you are asking how to modify that. If that is the case, this is a bad idea.

The build server should have its own copy of the git repository, and it will be locally managed by git on the build server. The build server's repository will be connected to the "main" git repository with a "remote", and you can issue the command git pull to update the local repository on the build server.

If you don't want to go to the trouble of setting up SSH or a gitolite server or something similar, you can use a file path as the "remote" location. So you could continue to mount the Linux server's file system on the build server, but instead of running the build out of that mounted path, clone the repository into another folder and run it from there.

I found an even elegant and simple solution to clearing cache

WebView obj;
obj.clearCache(true);

http://developer.android.com/reference/android/webkit/WebView.html#clearCache%28boolean%29

I have been trying to figure out the way to clear the cache, but all we could do from the above mentioned methods was remove the local files, but it never clean the RAM.

The API clearCache, frees up the RAM used by the webview and hence mandates that the webpage be loaded again.

If your matplotlib version is above 1.4, it is also possible to use

IPython 3.x and above

%matplotlib notebook

import matplotlib.pyplot as plt

older versions

%matplotlib nbagg

import matplotlib.pyplot as plt

Both will activate the nbagg backend, which enables interactivity.

You only need to prefix an if statement with @ if you're not already inside a razor code block.

Edit: You have a couple of things wrong with your code right now.

You're declaring nmb, but never actually doing anything with the value. So you need figure out what that's supposed to actually be doing. In order to fix your code, you need to make a couple of tiny changes:

@if (ViewBag.Articles != null)
{
    int nmb = 0;
    foreach (var item in ViewBag.Articles)
    {
        if (nmb % 3 == 0)
        {
            @:<div class="row"> 
        }

        <a href="@Url.Action("Article", "Programming", new { id = item.id })">
            <div class="tasks">
                <div class="col-md-4">
                    <div class="task important">
                        <h4>@item.Title</h4>
                        <div class="tmeta">
                            <i class="icon-calendar"></i>
                                @item.DateAdded - Pregleda:@item.Click
                            <i class="icon-pushpin"></i> Authorrr
                        </div>
                    </div>
                </div>
            </div>
        </a>
        if (nmb % 3 == 0)
        {
            @:</div>
        }
    }
}

The important part here is the @:. It's a short-hand of <text></text>, which is used to force the razor engine to render text.

One other thing, the HTML standard specifies that a tags can only contain inline elements, and right now, you're putting a div, which is a block-level element, inside an a.

This isn't an answer. I just want to show that IF NOT EXISTS(...) INSERT method isn't safe. You have to execute first Session #1 and then Session #2. After v #2 you will see that without an UNIQUE index you could get duplicate pairs (SoftwareName,SoftwareSystemType). Delay from session #1 is used to give you enough time to execute the second script (session #2). You could reduce this delay.

Session #1 (SSMS > New Query > F5 (Execute))

This is my 2 cents for adatetime string. On MM DD YYYY systems switch the first and second %DATE:~ entries.

    REM ====================================================================================
    REM CREATE UNIQUE DATETIME STRING FOR ADDING TO FILENAME
    REM ====================================================================================
    REM Can handle dd DDxMMxYYYY and DDxMMxYYYY > CREATES YYYYMMDDHHMMSS (x= any character)
    REM ====================================================================================
    REM CHECK for SHORTDATE dd DDxMMxYYYY 
    IF "%DATE:~0,1%" GTR "3" (
        SET DATETIME=%DATE:~9,4%%DATE:~6,2%%DATE:~3,2%%TIME:~0,2%%TIME:~3,2%%TIME:~6,2%

If you installed php with homebrew, then check if your apache2.conf file is using homebrew version of php5.so file.

Configuring a button (or any widget) in Tkinter is done by calling a configure method "config"

To change the size of a button called button1 you simple call

button1.config( height = WHATEVER, width = WHATEVER2 )

If you know what size you want at initialization these options can be added to the constructor.

button1 = Button(self, text = "Send", command = self.response1, height = 100, width = 100) 

As far as I can see it you can use the following:

ls | xargs -n 1 cp -i file.dat

The -i option of cp command means that you will be asked whether to overwrite a file in the current directory with the file.dat. Though it is not a completely automatic solution it worked out for me.

You can use form binding and 3 methods in your Controller. Here's what I do

class ActivitiesController extends BaseController {
    public function getAdd() {
        return $this->form();
    }
    public function getEdit($id) {
        return $this->form($id);
    }
    protected function form($id = null) {
        $activity = ! is_null($id) ? Activity::findOrFail($id) : new Activity;

        //
        // Your logic here
        //

        $form = View::make('path.to.form')
            ->with('activity', $activity);

        return $form->render(); 
    }
}

And in my views I have

{{ Form::model($activity, array('url' => "/admin/activities/form/{$activity->id}", 'method' => 'post')) }}
{{ Form::close() }}

Email: {
                      group: '.col-sm-3',
                      enabled: false,
                      validators: {
                          //emailAddress: {
                          //    message: 'Email not Valid'
                          //},
                          regexp: {
                              regexp: '^[^@\\s]+@([^@\\s]+\\.)+[^@\\s]+$',
                              message: 'Email not Valid'
                          },
                      }
                  },

Edit: With the introduction of Hooks it is possible to implement a lifecycle kind of behavior as well as the state in the functional Components. Currently

Hooks are a new feature proposal that lets you use state and other React features without writing a class. They are released in React as a part of v16.8.0

useEffect hook can be used to replicate lifecycle behavior, and useState can be used to store state in a function component.

Basic syntax:

useEffect(callbackFunction, [dependentProps]) => cleanupFunction

You can implement your use case in hooks like

const grid = (props) => {
    console.log(props);
    let {skuRules} = props;

    useEffect(() => {
        if(!props.fetched) {
            props.fetchRules();
        }
        console.log('mount it!');
    }, []); // passing an empty array as second argument triggers the callback in useEffect only after the initial render thus replicating `componentDidMount` lifecycle behaviour

    return(
        <Content title="Promotions" breadcrumbs={breadcrumbs} fetched={skuRules.fetched}>
            <Box title="Sku Promotion">
                <ActionButtons buttons={actionButtons} />
                <SkuRuleGrid 
                    data={skuRules.payload}
                    fetch={props.fetchSkuRules}
                />
            </Box>      
        </Content>  
    )
}

useEffect can also return a function that will be run when the component is unmounted. This can be used to unsubscribe to listeners, replicating the behavior of componentWillUnmount:

Eg: componentWillUnmount

useEffect(() => {
    window.addEventListener('unhandledRejection', handler);
    return () => {
       window.removeEventListener('unhandledRejection', handler);
    }
}, [])

To make useEffect conditional on specific events, you may provide it with an array of values to check for changes:

Eg: componentDidUpdate

componentDidUpdate(prevProps, prevState) {
     const { counter } = this.props;
     if (this.props.counter !== prevState.counter) {
      // some action here
     }
}

Hooks Equivalent

useEffect(() => {
     // action here
}, [props.counter]); // checks for changes in the values in this array

If you include this array, make sure to include all values from the component scope that change over time (props, state), or you may end up referencing values from previous renders.

There are some subtleties to using useEffect; check out the API Here.

Before v16.7.0

The property of function components is that they don't have access to Reacts lifecycle functions or the this keyword. You need to extend the React.Component class if you want to use the lifecycle function.

class Grid extends React.Component  {
    constructor(props) {
       super(props)
    }

    componentDidMount () {
        if(!this.props.fetched) {
            this.props.fetchRules();
        }
        console.log('mount it!');
    }
    render() {
    return(
        <Content title="Promotions" breadcrumbs={breadcrumbs} fetched={skuRules.fetched}>
            <Box title="Sku Promotion">
                <ActionButtons buttons={actionButtons} />
                <SkuRuleGrid 
                    data={skuRules.payload}
                    fetch={props.fetchSkuRules}
                />
            </Box>      
        </Content>  
    )
  }
}

Function components are useful when you only want to render your Component without the need of extra logic.

If all you want is to not show the traceback, make your code like this:

## all your app logic here
def main():
   ## whatever your app does.


if __name__ == "__main__":
   try:
      main()
   except KeyboardInterrupt:
      # do nothing here
      pass

(Yes, I know that this doesn't directly answer the question, but it's not really clear why needing a try/except block is objectionable -- maybe this makes it less annoying to the OP)

You can also do it without modulus. Just reset your counter when it matches.

if($counter == 2) { // matches every 3 iterations
   echo 'image-file';
   $counter = 0; 
}

A Super key is a set or one of more columns to uniquely identify rows in a table.

Candidate keys are selected from the set of super keys, the only thing we take care while selecting candidate key is: It should not have any redundant attribute. That’s the reason they are also termed as minimal super key.

In Employee table there are Three Columns : Emp_Code,Emp_Number,Emp_Name

Super keys:

All of the following sets are able to uniquely identify rows of the employee table.

{Emp_Code}
{Emp_Number}
{Emp_Code, Emp_Number}
{Emp_Code, Emp_Name}
{Emp_Code, Emp_Number, Emp_Name}
{Emp_Number, Emp_Name}

Candidate Keys:

As I stated above, they are the minimal super keys with no redundant attributes.

{Emp_Code}
{Emp_Number}

Primary key:

Primary key is being selected from the sets of candidate keys by database designer. So Either {Emp_Code} or {Emp_Number} can be the primary key.

Go to SSMS >> Tools >> Options >> Environment >> AutoRecover

There are two different settings:

1) Save AutoRecover Information Every Minutes

This option will save the SQL Query file at certain interval. Set this option to minimum value possible to avoid loss. If you have set this value to 5, in the worst possible case, you can lose last 5 minutes of the work.

2) Keep AutoRecover Information for Days

This option will preserve the AutoRecovery information for specified days. Though, I suggest in case of accident open SQL Server Management Studio right away and recover your file. Do not procrastinate this important task for future dates.

I managed to fix it :D heres the code.

var divh = document.getElementById('first').offsetHeight;
$("#first").css('height', '100px');
$("div:first").click(function() {
  $("#first").animate({
    height: divh
  }, 1000);
});

copy your war file to /tmp now extract the contents:

cp warfile.war /tmp
cd /tmp
unzip warfile.war
cd WEB-INF
nano web.xml (or vim or any editor you want to use)
cd ..
zip -r -u warfile.war WEB-INF

now you have in /tmp/warfile.war your file updated.

It because every time

void pthread_exit(void *ret);

will be called from thread function so which ever you want to return simply its pointer pass with pthread_exit().

Now at

int pthread_join(pthread_t tid, void **ret);

will be always called from where thread is created so here to accept that returned pointer you need double pointer ..

i think this code will help you to understand this

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

void* thread_function(void *ignoredInThisExample)
{
    char *a = malloc(10);
    strcpy(a,"hello world");
    pthread_exit((void*)a);
}
int main()
{
    pthread_t thread_id;
    char *b;

    pthread_create (&thread_id, NULL,&thread_function, NULL);

    pthread_join(thread_id,(void**)&b); //here we are reciving one pointer 
                                        value so to use that we need double pointer 
    printf("b is %s\n",b); 
    free(b); // lets free the memory

}

I would prefer using JConsole for application monitoring, and it does have graphical view. If you’re using JDK 5.0 or above then it’s the best. Please refer to this using jconsole page for more details.

I have been primarily using it for GC tuning and finding bottlenecks.

 import base64
 from PIL import Image
 import io
 image = base64.b64decode(str('stringdata'))       
 fileName = 'test.jpeg'

 imagePath = ('D:\\base64toImage\\'+"test.jpeg")
 img = Image.open(io.BytesIO(image))
 img.save(imagePath, 'jpeg')

If you have the code to log_out(), rewrite it. Most likely, you can do:

static FILE *logfp = ...;

void log_out(const char *fmt, ...)
{
    va_list args;

    va_start(args, fmt);
    vfprintf(logfp, fmt, args);
    va_end(args);
}

If there is extra logging information needed, that can be printed before or after the message shown. This saves memory allocation and dubious buffer sizes and so on and so forth. You probably need to initialize logfp to zero (null pointer) and check whether it is null and open the log file as appropriate - but the code in the existing log_out() should be dealing with that anyway.

The advantage to this solution is that you can simply call it as if it was a variant of printf(); indeed, it is a minor variant on printf().

If you don't have the code to log_out(), consider whether you can replace it with a variant such as the one outlined above. Whether you can use the same name will depend on your application framework and the ultimate source of the current log_out() function. If it is in the same object file as another indispensable function, you would have to use a new name. If you cannot work out how to replicate it exactly, you will have to use some variant like those given in other answers that allocates an appropriate amount of memory.

void log_out_wrapper(const char *fmt, ...)
{
    va_list args;
    size_t  len;
    char   *space;

    va_start(args, fmt);
    len = vsnprintf(0, 0, fmt, args);
    va_end(args);
    if ((space = malloc(len + 1)) != 0)
    {
         va_start(args, fmt);
         vsnprintf(space, len+1, fmt, args);
         va_end(args);
         log_out(space);
         free(space);
    }
    /* else - what to do if memory allocation fails? */
}

Obviously, you now call the log_out_wrapper() instead of log_out() - but the memory allocation and so on is done once. I reserve the right to be over-allocating space by one unnecessary byte - I've not double-checked whether the length returned by vsnprintf() includes the terminating null or not.

while setting the color you can set color like this

[UIColor colorWithRed:19/255.0 green:144/255.0 blue:255/255.0 alpha:1.0]

This is an older thread, but I just searched and found it. I am new to using Web Developer Tools: primarily Firefox Developer Tools (Firefox v.51), but also Chrome DevTools (Chrome v.56)].

I wasn't able to run functions from the Developer Tools console, but I then found this

https://developer.mozilla.org/en-US/docs/Tools/Scratchpad

and I was able to add code to the Scratchpad, highlight and run a function, outputted to console per the attched screenshot.

I also added the Chrome "Scratch JS" extension: it looks like it provides the same functionality as the Scratchpad in Firefox Developer Tools (screenshot below).

I found the proper way. It's very simple. In resource describe following:

android:choiceMode="singleChoice"
android:listSelector="#666666"

(or you may specify a resource link instead of color value)

Programmatical:

listView.setSelector(Drawable selector);
listView.setSelector(int resourceId);
listView.setChoiceMode(int mode);

mode can be one of these: AbsListView.CHOICE_MODE_SINGLE, AbsListView.CHOICE_MODE_MULTIPLE, AbsListView.CHOICE_MODE_NONE (default)

(AbsListView is the abstract ancestor for the ListView class)

P.S. manipulations with onItemClick and changing view background are bankrupt, because a view itself is a temporary object. Hence you must not to track a view.

If our list is long enough, the views associated with scrolled out items will be removed from hierarchy, and will be recreated when those items will shown again (with cached display options, such as background). So, the view we have tracked is now not an actual view of the item, and changing its background does nothing to the actual item view. As a result we have multiple items selected.

sudo apt-get install docker # DO NOT do this

is a different library on ubuntu.

Use sudo apt-get install docker-ce to install the correct docker.

Just using Data Binding syntax. For example,

<Button x:Name="btn" 
         Content="Click" 
         Command="{Binding ClickCmd}" 
         CommandParameter="{Binding ElementName=btn,Path=Content}" /> 

Not only can we use Data Binding to get some data from View Models, but also pass data back to View Models. In CommandParameter, must use ElementName to declare binding source explicitly.

Don't edit the vector assets directly. If you're using a vector drawable in an ImageButton, just choose your color in android:tint.

<ImageButton
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:id="@+id/button"
        android:src="@drawable/ic_more_vert_24dp"
        android:tint="@color/primary" />

Flat and simple config without rewrite, can work in some cases:

location / {
    fastcgi_pass unix:/var/run/php5-fpm.sock;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME /home/webuser/site/index.php;
}

Generically, do/while is good for any sort of loop construct where one must execute the loop at least once. It is possible to emulate this sort of looping through either a straight while or even a for loop, but often the result is a little less elegant. I'll admit that specific applications of this pattern are fairly rare, but they do exist. One which springs to mind is a menu-based console application:

do {
    char c = read_input();

    process_input(c);
} while (c != 'Q');

You can try FakeHttpContext:

using (new FakeHttpContext())
{
   HttpContext.Current.Session["CustomerId"] = "customer1";       
}

Is very easy, this work for me:

PHP:

set_time_limit(300); // Time in seconds, max_execution_time

Here is the PHP documentation

In C++0x you will be able to initialize containers just like arrays

http://www2.research.att.com/~bs/C++0xFAQ.html#init-list

Numbers from 987-65-4320 to 987-65-4329 are reserved for use in advertisements.

This works for me, I only need first numbers in string:

TO_NUMBER(regexp_substr(h.HIST_OBSE, '\.*[[:digit:]]+\.*[[:digit:]]*'))

the field had the following string: "(43 Paginas) REGLAS DE PARTICIPACION".

result field: 43

The assumption by other answers that one needs to sort the data is not correct.

The following code does not sort the entire array, but only 200-element segments of it, and thereby runs the fastest.

Sorting only k-element sections completes the pre-processing in linear time, O(n), rather than the O(n.log(n)) time needed to sort the entire array.

#include <algorithm>
#include <ctime>
#include <iostream>

int main() {
    int data[32768]; const int l = sizeof data / sizeof data[0];

    for (unsigned c = 0; c < l; ++c)
        data[c] = std::rand() % 256;

    // sort 200-element segments, not the whole array
    for (unsigned c = 0; c + 200 <= l; c += 200)
        std::sort(&data[c], &data[c + 200]);

    clock_t start = clock();
    long long sum = 0;

    for (unsigned i = 0; i < 100000; ++i) {
        for (unsigned c = 0; c < sizeof data / sizeof(int); ++c) {
            if (data[c] >= 128)
                sum += data[c];
        }
    }

    std::cout << static_cast<double>(clock() - start) / CLOCKS_PER_SEC << std::endl;
    std::cout << "sum = " << sum << std::endl;
}

This also "proves" that it has nothing to do with any algorithmic issue such as sort order, and it is indeed branch prediction.

if (new TimeSpan(11,59,0) <= currentTime.TimeOfDay && new TimeSpan(13,01,0) >=  currentTime.TimeOfDay)
{
   //match found
}

if you really want to parse a string into a TimeSpan, then you can use:

    TimeSpan start = TimeSpan.Parse("11:59");
    TimeSpan end = TimeSpan.Parse("13:01");

It means

myclass *p = NULL;
*p = ...;  // illegal: dereferencing NULL pointer
... = *p;  // illegal: dereferencing NULL pointer
p->meth(); // illegal: equivalent to (*p).meth(), which is dereferencing NULL pointer

myclass *p = /* some legal, non-NULL pointer */;
*p = ...;  // Ok
... = *p;  // Ok
p->meth(); // Ok, if myclass::meth() exists

basically, almost anything involving (*p) or implicitly involving (*p), e.g. p->... which is a shorthand for (*p). ...; except for pointer declaration.

Action is null means that no Action in given SOAP Message (Request XML). You must set Action before SOAP call:

java.net.URL endpoint = new URL("<URL>"); //sets URL

MimeHeaders headers = message.getMimeHeaders(); // getting MIME Header

headers.addHeader("SOAPAction", "<SOAP Action>"); //add Action To Header

SOAPMessage response = soapConnection.call(<SOAPMessage>, endpoint); //then Call

soapConnection.close(); // then Close the connection

There are multiple answers based on what you are doing with the string.

1) Using the string as an id (will not be modified). Passing it in by const reference is probably the best idea here: (std::string const&)

2) Modifying the string but not wanting the caller to see that change. Passing it in by value is preferable: (std::string)

3) Modifying the string but wanting the caller to see that change. Passing it in by reference is preferable: (std::string &)

4) Sending the string into the function and the caller of the function will never use the string again. Using move semantics might be an option (std::string &&)

if you post a file from mobile device or other

    byte[] fileData = null;
    using (var binaryReader = new BinaryReader(Request.Files[0].InputStream))
    {
        fileData = binaryReader.ReadBytes(Request.Files[0].ContentLength);
    }

A flexible solution with Java 8 lambda that lets you provide a Consumer that will process the output (eg. log it) line by line. run() is a one-liner with no checked exceptions thrown. Alternatively to implementing Runnable, it can extend Thread instead as other answers suggest.

class StreamGobbler implements Runnable {
    private InputStream inputStream;
    private Consumer<String> consumeInputLine;

    public StreamGobbler(InputStream inputStream, Consumer<String> consumeInputLine) {
        this.inputStream = inputStream;
        this.consumeInputLine = consumeInputLine;
    }

    public void run() {
        new BufferedReader(new InputStreamReader(inputStream)).lines().forEach(consumeInputLine);
    }
}

You can then use it for example like this:

public void runProcessWithGobblers() throws IOException, InterruptedException {
    Process p = new ProcessBuilder("...").start();
    Logger logger = LoggerFactory.getLogger(getClass());

    StreamGobbler outputGobbler = new StreamGobbler(p.getInputStream(), System.out::println);
    StreamGobbler errorGobbler = new StreamGobbler(p.getErrorStream(), logger::error);

    new Thread(outputGobbler).start();
    new Thread(errorGobbler).start();
    p.waitFor();
}

Here the output stream is redirected to System.out and the error stream is logged on the error level by the logger.

Just to correct and slightly extend Scott Wilson answer.
You can use data.table's setnames function on data.frames too.

Do not expect speed up of the operation but you can expect the setnames to be more efficient for memory consumption as it updates column names by reference. This can be tracked with address function, see below.

library(data.table)
set.seed(123)
n = 1e8

df = data.frame(bad=sample(1:3, n, TRUE), worse=rnorm(n))
address(df)
#[1] "0x208f9f00"
colnames(df) <- c("good", "better")
address(df)
#[1] "0x208fa1d8"
rm(df)

dt = data.table(bad=sample(1:3, n, TRUE), worse=rnorm(n))
address(dt)
#[1] "0x535c830"
setnames(dt, c("good", "better"))
address(dt)
#[1] "0x535c830"
rm(dt)

So if you are hitting your memory limits you may consider to use this one instead.

Not an official answer by any means (just a guess based on using the language), but Python allows you to use lists as stacks (e.g., section 5.1.1 of the tutorial). However, a list is still first of all a list, so the operations that are common to both use list terms (i.e., append) rather than stack terms (i.e., push). Since a pop operation isn't that common in lists (though 'removeLast' could have been used), they defined a pop() but not a push().

You want the (standard) POSIXt type from base R that can be had in 'compact form' as a POSIXct (which is essentially a double representing fractional seconds since the epoch) or as long form in POSIXlt (which contains sub-elements). The cool thing is that arithmetic etc are defined on this -- see help(DateTimeClasses)

Quick example:

R> now <- Sys.time()
R> now
[1] "2009-12-25 18:39:11 CST"
R> as.numeric(now)
[1] 1.262e+09
R> now + 10  # adds 10 seconds
[1] "2009-12-25 18:39:21 CST"
R> as.POSIXlt(now)
[1] "2009-12-25 18:39:11 CST"
R> str(as.POSIXlt(now))
 POSIXlt[1:9], format: "2009-12-25 18:39:11"
R> unclass(as.POSIXlt(now))
$sec

As for reading them in, see help(strptime)

As for difference, easy too:

R> Jan1 <- strptime("2009-01-01 00:00:00", "%Y-%m-%d %H:%M:%S")
R> difftime(now, Jan1, unit="week")
Time difference of 51.25 weeks

Lastly, the zoo package is an extremely versatile and well-documented container for matrix with associated date/time indices.

It's 'Dirty' way of using memory addresses. When you return an address (pointer) you don't know whether it belongs to local scope of a function. It's just an address. Now that you invoked the 'foo' function, that address (memory location) of 'a' was already allocated there in the (safely, for now at least) addressable memory of your application (process). After the 'foo' function returned, the address of 'a' can be considered 'dirty' but it's there, not cleaned up, nor disturbed/modified by expressions in other part of program (in this specific case at least). A C/C++ compiler doesn't stop you from such 'dirty' access (might warn you though, if you care). You can safely use (update) any memory location that is in the data segment of your program instance (process) unless you protect the address by some means.

Router:-

...
.when('/enquiry/:page', {
    template: '<div ng-include src="templateUrl" onload="onLoad()"></div>',
    controller: 'enquiryCtrl'
})
...

Controller:-

...
// template onload event
$scope.onLoad = function() {
    console.log('onLoad()');
    f_tcalInit();  // or other onload stuff
}

// initialize
$scope.templateUrl = 'ci_index.php/adminctrl/enquiry/'+$routeParams.page;
...

I believe it is a weakness in angularjs that $routeParams is NOT visible inside the router. A tiny enhancement would make a world of difference during implementation.

use ClassName.this.variableName to reference the non-final variable

To start:

Pros:

• It is the unique way of implementing a variable number of nested loops (and the only elegant way of implementing a big constant number of nested loops).

Cons:

• Recursive methods will often throw a StackOverflowException when processing big sets. Recursive loops don't have this problem though.

Building on the accepted answer, this will work with ngRepeat, filterand handle expections better:

Controller:

vm.remove = function(item, array) {
  var index = array.indexOf(item);
  if(index>=0)
    array.splice(index, 1);
}

View:

ng-click="vm.remove(item,$scope.bdays)"

If there's a chance that you will reuse this code, then I would probably make the effort to go with an object-oriented perspective. Using the global namespace can be dangerous -- you run the risk of hard to find bugs due to variable names that get reused. Typically I start by using an object-oriented approach for anything more than a simple callback so that I don't have to do the re-write thing. Any time that you have a group of related functions in javascript, I think, it's a candidate for an object-oriented approach.

i think you use this method to compress the bitmap

BitmapFactory.Option imageOpts = new BitmapFactory.Options ();
imageOpts.inSampleSize = 2;   // for 1/2 the image to be loaded
Bitmap thumb = Bitmap.createScaledBitmap (BitmapFactory.decodeFile(photoPath, imageOpts), 96, 96, false);

Use this.getClass().getCanonicalName() to get the full class name.

Note that a package / class name ("a.b.C") is different from the path of the .class files (a/b/C.class), and that using the package name / class name to derive a path is typically bad practice. Sets of class files / packages can be in multiple different class paths, which can be directories or jar files.

By default, it begins by processing the first target that does not begin with a . aka the default goal; to do that, it may have to process other targets - specifically, ones the first target depends on.

The GNU Make Manual covers all this stuff, and is a surprisingly easy and informative read.

Try looking at decode string encoded in utf-8 format in android but it doesn't look like your string is encoded with anything particular. What do you think the output should be?

width: intrinsic;           /* Safari/WebKit uses a non-standard name */
width: -moz-max-content;    /* Firefox/Gecko */
width: -webkit-max-content; /* Chrome */

The biggest issue being missed by most solutions here is that an element's width is often changed by CSS based on where it is scoped in html.

If I was to determine offsetWidth of an element by appending a clone of it to body when it has styles that only apply in its current scope I would get the wrong width.

for example:

//css

.module-container .my-elem{ border: 60px solid black; }

now when I try to determine my-elem's width in context of body it will be out by 120px. You could clone the module container instead, but your JS shouldn't have to know these details.

I haven't tested it but essentially Soul_Master's solution appears to be the only one that could work properly. But unfortunately looking at the implementation it will likely be costly to use and bad for performance (as most of the solutions presented here are as well.)

If at all possible then use visibility: hidden instead. This will still render the element, allowing you to calculate width without all the fuss.

this may also work.

There is an extension called Hinterland for jupyter, which automatically displays the drop down menu when typing. There are also some other useful extensions.

In order to install extensions, you can follow the guide on this github repo. To easily activate extensions, you may want to use the extensions configurator.

Most .NET jobs I've run across also either explicitly or implicitly assume some knowledge of SQL-based RDBMSes. While it's not "part of the description", it's usually part of the job.

When using the checkbox HtmlHelper, I much prefer to work with the posted checkbox form data as an array. I don't really know why, I know the other methods work, but I think I just prefer to treat comma separated strings as an array as much as possible.

So doing a 'checked' or true test would be:

//looking for [true],[false]
bool isChecked = form.GetValues(key).Contains("true"); 

Doing a false check would be:

//looking for [false],[false] or [false]
bool isNotChecked = !form.GetValues(key).Contains("true"); 

The main difference is to use GetValues as this returns as an array.

This happens because Oracle dropped support for Windows XP (which doesn't have RegDeleteKeyExA used by the installer in its ADVAPI32.DLL by the way) as described in http://mail.openjdk.java.net/pipermail/openjfx-dev/2013-July/009005.html. Yet while the official support for XP has ended, the Java binaries are still (as of Java 8u20 EA b05 at least) XP-compatible - only the installer isn't...

Because of that, the solution is actually quite easy:

1. get 7-Zip (or any other good unpacker), unpack the distribution .exe manually, it has one .zip file inside of it (tools.zip), extract it too,

2. use unpack200 from JDK8 to unpack all .pack files to .jar files (older unpacks won't work properly); JAVA_HOME environment variable should be set to your Java unpack root, e.g. "C:\Program Files\Java\jdk8" - you can specify it implicitly by e.g.

   SET JAVA_HOME=C:\Program Files\Java\jdk8
   

   • Unpack all files with a single command (in batch file):

     FOR /R %%f IN (*.pack) DO "%JAVA_HOME%\bin\unpack200.exe" -r -v "%%f" "%%~pf%%~nf.jar"
     

   • Unpack all files with a single command (command line from JRE root):

     FOR /R %f IN (*.pack) DO "bin\unpack200.exe" -r -v "%f" "%~pf%~nf.jar"
     

   • Unpack by manually locating the files and unpacking them one-by-one:

     %JAVA_HOME%\bin\unpack200 -r packname.pack packname.jar
     

   where packname is for example rt

3. point the tool you want to use (e.g. Netbeans) to the %JAVA_HOME% and you're good to go.

Note: you probably shouldn't do this just to use Java 8 in your web browser or for any similar reason (installing JRE 8 comes to mind); security flaws in early updates of major Java version releases are (mind me) legendary, and adding to that no real support for neither XP nor Java 8 on XP only makes matters much worse. Not to mention you usually don't need Java in your browser (see e.g. http://nakedsecurity.sophos.com/2013/01/15/disable-java-browsers-homeland-security/ - the topic is already covered on many pages, just Google it if you require further info). In any case, AFAIK the only thing required to apply this procedure to JRE is to change some of the paths specified above from \bin\ to \lib\ (the file placement in installer directory tree is a bit different) - yet I strongly advise against doing it.

See also: How can I get the latest JRE / JDK as a zip file rather than EXE or MSI installer?, JRE 1.7 - java version - returns: java/lang/NoClassDefFoundError: java/lang/Object

select min(sal) from (select distinct sal from employee order by sal DESC) where rownum<=N;

I asked a similary question on this Stack Overflow post to create a class factory which created simple types. The outcome was this answer which had a working version of the class factory. Here is a snippet of the answer:

def Struct(*args, **kwargs):
    def init(self, *iargs, **ikwargs):
        for k,v in kwargs.items():
            setattr(self, k, v)
        for i in range(len(iargs)):
            setattr(self, args[i], iargs[i])
        for k,v in ikwargs.items():
            setattr(self, k, v)

    name = kwargs.pop("name", "MyStruct")
    kwargs.update(dict((k, None) for k in args))
    return type(name, (object,), {'__init__': init, '__slots__': kwargs.keys()})

>>> Person = Struct('fname', 'age')
>>> person1 = Person('Kevin', 25)
>>> person2 = Person(age=42, fname='Terry')
>>> person1.age += 10
>>> person2.age -= 10
>>> person1.fname, person1.age, person2.fname, person2.age
('Kevin', 35, 'Terry', 32)
>>>

You could use some variation of this to create default values which is your goal (there is also an answer in that question which deals with this).

Non of the answers helped me. But a trick did - I just cleared the title of the view controller that pushed (where the back button is going to) just before pushing it.

So when the previous view doesn't have a title, on iOS 7 the back button will only have an arrow, without text.

On viewWillAppear of the pushing view, I placed back the original title.

You can simply use jQuery UI Dialog

One of the possible way to get result as below , hope this will help.

declare @start int
declare @end int
SET @start = '5000';  -- 0 , 5000 ,
SET @end = '10000'; -- 5001, 10001
SELECT * FROM ( 
  SELECT TABLE_NAME,TABLE_TYPE, ROW_NUMBER() OVER (ORDER BY TABLE_NAME) as row FROM information_schema.tables
 ) a WHERE a.row > @start and a.row <= @end

There are two different ways of generating a UUID.

If you just need a unique ID, you want a version 1 or version 4.

• Version 1: This generates a unique ID based on a network card MAC address and a timer. These IDs are easy to predict (given one, I might be able to guess another one) and can be traced back to your network card. It's not recommended to create these.

• Version 4: These are generated from random (or pseudo-random) numbers. If you just need to generate a UUID, this is probably what you want.

If you need to always generate the same UUID from a given name, you want a version 3 or version 5.

• Version 3: This generates a unique ID from an MD5 hash of a namespace and name. If you need backwards compatibility (with another system that generates UUIDs from names), use this.

• Version 5: This generates a unique ID from an SHA-1 hash of a namespace and name. This is the preferred version.

Here you go:

var life={
        users:{
             guys:function(){ life.mameAndDestroy(life.users.girls); },
             girls:function(){ life.kiss(life.users.guys); }
        },
        mameAndDestroy : function(group){ 
          alert("mameAndDestroy");
          group();
        },
        kiss : function(group){
          alert("kiss");
          //could call group() here, but would result in infinite loop
        }
};

life.users.guys();
life.users.girls();

Also, make sure you don't have a comma after the "girls" definition. This will cause the script to crash in IE (any time you have a comma after the last item in an array in IE it dies).

See it run

For those actually wanting to do a JOIN you can also use:

UPDATE a
SET price = b_alias.unit_price
FROM      a AS a_alias
LEFT JOIN b AS b_alias ON a_alias.b_fk = b_alias.id
WHERE a_alias.unit_name LIKE 'some_value' 
AND a.id = a_alias.id;

You can use the a_alias in the SET section on the right of the equals sign if needed. The fields on the left of the equals sign don't require a table reference as they are deemed to be from the original "a" table.

Make sure you have python in path,if not,win key + r, type in "%appdata%"(without the qotes) open local directory, then go to Programs directory ,open python and then select your python version directory. Click on file tab and select copy path and close file explorer.

Then do win key + r again, type control and hit enter. search for environment variables. click on the result, you will get a window. In the bottom right corner click on environmental variables. In the system side find path, select it and click on edit. In the new window, click on new and paste the path in there. Click ok and then apply in the first window. Restart your PC. Then do win + r for the last time, type cmd and do ctrl + shift + enter. Grant the previliges and open file explorer, goto your script and copy its path. Go back into cmd , type in "python" and paste the path and hit enter. Done

Eclipse Runnable JAR File

Create a Java Project – RunnableJAR

• If any jar files are used then add them to project build path.
• Select the class having main() while creating Runnable Jar file.

Main Class

public class RunnableMainClass {
    public static void main(String[] args) throws InterruptedException {
        System.out.println("Name : "+args[0]);
        System.out.println(" ID  : "+args[1]);
    }
}

Run Jar file using java program (cmd) by supplying arguments and get the output and display in eclipse console.

public class RunJar { 
    static StringBuilder sb = new StringBuilder();
    public static void main(String[] args) throws IOException {
        String jarfile = "D:\\JarLocation\\myRunnable.jar";
        String name = "Yash";
        String id = "777";

        try { // jarname arguments has to be saperated by spaces
            Process process = Runtime.getRuntime().exec("cmd.exe start /C java -jar "+jarfile+" "+name+" "+id);
                    //.exec("cmd.exe /C start dir java -jar "+jarfile+" "+name+" "+id+" dir");
            BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream ()));
            String line = null;
            while ((line = br.readLine()) != null){
                sb.append(line).append("\n");
            }
            System.out.println("Console OUTPUT : \n"+sb.toString());
            process.destroy();
        }catch (Exception e){
            System.err.println(e.getMessage());
        }
   }
}

In Eclipse to find Short cuts:

The reason why @Resource(name = "{your child class name}") works but @Autowired sometimes don't work is because of the difference of their Matching sequence

Matching sequence of @Autowire
Type, Qualifier, Name

Matching sequence of @Resource
Name, Type, Qualifier

The more detail explanation can be found here:
Inject and Resource and Autowired annotations

In this case, different child class inherited from the parent class or interface confuses @Autowire, because they are from same type; As @Resource use Name as first matching priority , it works.
