None of the above worked on Sublime Text 3 on Windows 10, Ctrl + Shift + ' with the Emmet Sublime Text 3 plugin works great and was the only working solution for me. Ctrl + Shift + T re-opens the last closed item and to my knowledge of Sublime, has done so since early builds of ST3 or late builds of ST2.

ssh -t 'command; bash -l'

will execute the command and then start up a login shell when it completes. For example:

ssh -t [email protected] 'cd /some/path; bash -l'

I'm running JMeter 2.8 (Windows 7) and received a message similar to that in the original post:

C:\>jmeter
Error: Unable to access jarfile C:\local\software\jMeter\apache-jmeter-2.8\binApacheJMeter.jar
errorlevel=1
Press any key to continue . . .

I'd created a Windows environment variable JMETER_BIN and set it to the JMeter path which I could see contained ApacheJMeter.jar (so it wasn't a question that the jar was missing).

I should have noticed at the time this portion of the error: "binApacheJMeter.jar"

When I went to the jmeter.bat file to troubleshoot, I noticed this line:

%JM_START% %JM_LAUNCH% %ARGS% %JVM_ARGS% -jar "%JMETER_BIN%ApacheJMeter.jar" %JMETER_CMD_LINE_ARGS%

and that caused me to revisit the "binApacheJMeter.jar" portion of the error.

What was happening was that the batch file was requiring a trailing slash on the end of the path in the JMETER_BIN environment variable to correctly specify the location of the .jar.

Once I corrected my environment variable, adding the trailing slash, all was wonderful.

YMMV, but this worked for me.

I use struct only when I need to hold some data without any member functions associated to it (to operate on the member data) and to access the data variables directly.

Eg: Reading/Writing data from files and socket streams etc. Passing function arguments in a structure where the function arguments are too many and function syntax looks too lengthy.

Technically there is no big difference between class and struture except default accessibility. More over it depends on programming style how you use it.

How do I change Android Studio editor's background color?

Changing Editor's Background

Open Preference > Editor (In IDE Settings Section) > Colors & Fonts > Darcula or Any item available there

IDE will display a dialog like this, Press 'No'

Darcula color scheme has been set for editors. Would you like to set Darcula as default Look and Feel?

Changing IDE's Theme

Open Preference > Appearance (In IDE Settings Section) > Theme > Darcula or Any item available there

Press OK. Android Studio will ask you to restart the IDE.

You could use GCJ to compile your Java program into native code.
At some time they even compiled Eclipse into a native version.

Surprised a multiline re.sub has not been suggested (Oh, because you've already split your string... But why?):

>>> import re
>>> a = "Foo\n \nBar\nBaz\n\n   Garply\n  \n"
>>> print a
Foo

Bar
Baz

        Garply


>>> print(re.sub(r'\n\s*\n','\n',a,re.MULTILINE))
Foo
Bar
Baz

Because of the way jQuery selectors are evaluated right-to-left, the quite readable li:not(:first) is slowed down by that evaluation.

An equally fast and easy to read solution is using the function version .not(":first"):

e.g.

$("li").not(":first").hide();

JSPerf: http://jsperf.com/fastest-way-to-select-all-expect-the-first-one/6

This is only few percentage points slower than slice(1), but is very readable as "I want all except the first one".

Only add this css to remove spinner on input of number

/* For Firefox */

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



/* Webkit browsers like Safari and Chrome */

input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
    -webkit-appearance: none;
    margin: 0;
}

That's something controlled by your terminal, not by printf.

printf simply sends a \t to the output stream (which can be a tty, a file etc), it doesn't send a number of spaces.

Take a look this: checklist-model.

It works with JavaScript arrays, and objects and it can use static HTML checkboxes, without ng-repeat

<label><input type="checkbox" checklist-model="roles" value="admin"> Administrator</label>
<label><input type="checkbox" checklist-model="roles" value="customer"> Customer</label>
<label><input type="checkbox" checklist-model="roles" value="guest"> Guest</label>
<label><input type="checkbox" checklist-model="roles" value="user"> User</label>

And the JavaScript side:

var app = angular.module("app", ["checklist-model"]);
app.controller('Ctrl4a', function($scope) {
    $scope.roles = [];
});

Use a list comprehension like this:

main_list = [item for item in list_2 if item not in list_1]

Output:

>>> list_1 = ["a", "b", "c", "d", "e"]
>>> list_2 = ["a", "f", "c", "m"] 
>>> 
>>> main_list = [item for item in list_2 if item not in list_1]
>>> main_list
['f', 'm']

Edit:

Like mentioned in the comments below, with large lists, the above is not the ideal solution. When that's the case, a better option would be converting list_1 to a set first:

set_1 = set(list_1)  # this reduces the lookup time from O(n) to O(1)
main_list = [item for item in list_2 if item not in set_1]

<button id="fwdbtn" style="color:red">Submit</button> 

Typically, no.

Streaming is seldom used over HTTP itself, and HTTP is seldom run over UDP. See, however, RTP.

For something as your example (in the comment), you're not showing a protocol for the resource. If that protocol were to be HTTP, then I wouldn't call the access "streaming"; even if it in some sense of the word is since it's sending a (possibly large) resource serially over a network. Typically, the resource will be saved to local disk before being played back, so the network transfer is not what's usually meant by "streaming".

As commenters have pointed out, though, it's certainly possible to really stream over HTTP, and that's done by some.

You can loop the array with a for loop and the object properties with for-in loops.

for (var i=0; i<result.length; i++)
    for (var name in result[i]) {
        console.log("Item name: "+name);
        console.log("Source: "+result[i][name].sourceUuid);
        console.log("Target: "+result[i][name].targetUuid);
    }

Using jQuery:

$('#play-pause').click(function(){
  if ( $('#video-over').css('visibility') == 'hidden' )
    $('#video-over').css('visibility','visible');
  else
    $('#video-over').css('visibility','hidden');
});

$query = "SELECT * FROM tableName";
$query_run = mysql_query($query);

$qty= 0;
while ($num = mysql_fetch_assoc ($query_run)) {
    $qty += $num['ColumnName'];
}
echo $qty;

Your database driver is missing. To solve the probelm

First install the driver

For ubuntu: For mysql database.

sudo apt-get install php5.6-mysql/php7.2-mysql

You also can search for other database systems.

You also can search for the driver:

sudo apt-cache search drivername

Then Run the cmd php artisan migrate

To configure IIS to run 32-bit applications you must follow these steps:

Open IIS
Go to current server – > Application Pools
Select the application pool your 32-bit application will run under
Click Advanced setting or Application Pool Default
Set Enable 32-bit Applications to True

If this option is not available to you, follow these next steps:

Go to %windir%\system32\inetsrv\
Execute the appcmd.exe tool:

To load your data in WebView. Call loadData() method of WebView

webView.loadData(yourData, "text/html; charset=utf-8", "UTF-8");

You can check this example

http://developer.android.com/reference/android/webkit/WebView.html

kill -9 $(ps -ef | grep 8084 | awk 'NR==2{print $2}')

NR is for the number of records in the input file. awk can find or replaces text

You can use find_all in the following way to find every a element that has an href attribute, and print each one:

from BeautifulSoup import BeautifulSoup

html = '''<a href="some_url">next</a>
<span class="class"><a href="another_url">later</a></span>'''

soup = BeautifulSoup(html)

for a in soup.find_all('a', href=True):
    print "Found the URL:", a['href']

The output would be:

Found the URL: some_url
Found the URL: another_url

Note that if you're using an older version of BeautifulSoup (before version 4) the name of this method is findAll. In version 4, BeautifulSoup's method names were changed to be PEP 8 compliant, so you should use find_all instead.

If you want all tags with an href, you can omit the name parameter:

href_tags = soup.find_all(href=True)

In my case this was actually a symptom of the server, hosted on AWS, lacking an IP for the external network. It would attempt to download namespaces from springframework.org and fail to make a connection.

If no other process is using the port 8080, Eventhough eclipse shows the port 8080 is used while starting the server in eclipse, first you have to stop the server by hitting the stop button in "Configure Tomcat"(which you can find in your start menu under tomcat folder), then try to start the server in eclipse then it will be started.

If any other process is using the port 8080 and as well as you no need to disturb it. then you can change the port.

The typical way to check for existence in many STL containers such as std::map, std::set, ... is:

const bool is_in = container.find(element) != container.end();

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

Easiest way is to use System.Linq as previously described

using System.Linq;

public int GetHighestValue(List<MyTypes> list)
{
    return list.Count > 0 ? list.Max(t => t.Age) : 0; //could also return -1
}

This is also possible with a Dictionary

using System.Linq;

public int GetHighestValue(Dictionary<MyTypes, OtherType> obj)
{
    return obj.Count > 0 ? obj.Max(t => t.Key.Age) : 0; //could also return -1
}

String array = array of characters ?

Or do you have a string with multiple words each of which should be an array element ?

String[] array = yourString.split(wordSeparator);

Yet Another Option:

>>> [re.split(r'(\d+)', s) for s in ('foofo21', 'bar432', 'foobar12345')]
[['foofo', '21', ''], ['bar', '432', ''], ['foobar', '12345', '']]

Below Kotlin code can help to you

Create Marker

        for (i in arrayList.indices) {
            val marker = googleMap!!.addMarker(
                MarkerOptions().position(
                    LatLng(
                        arrayList[i].location_latitude!!.toDoubleOrNull()!!,
                        arrayList[i].location_latitude!!.toDoubleOrNull()!!
                    )
                ).title(arrayList[i].business_name)
                    .icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_marker))
            )
            marker.tag = i
        }

Marker Click

        googleMap!!.setOnMarkerClickListener { marker ->
            Log.d(TAG, "Clicked on  ${marker.tag}")
            true
        }

I have used NuSOAP in the past. I liked it because it is just a set of PHP files that you can include. There is nothing to install on the web server and no config options to change. It has WSDL support as well which is a bonus.

I think something like this would work, upgrading the @Marc code:

//view-all parameter does NOT exist  
$params = $_GET;  
if(!isset($_GET['view-all'])){  
  //Adding view-all parameter  
  $params['view-all'] = 'Yes';  
}  
else{  
  //view-all parameter does exist!  
  $params['view-all'] = ($params['view-all'] == 'Yes' ? 'No' : 'Yes');  
}
$new_url = $_SERVER['PHP_SELF'].'?'.http_build_query($params);

Or spin Linux instance for SFTP Gateway in your AWS infrastructure that saves uploaded files to your Amazon S3 bucket.

Just use the plain ol' class selector.

$('#my_id .my_class')

It doesn't matter if the element also has other classes. It has the .my_class class, and it's somewhere inside #my_id, so it will match that selector.

Regarding performance

According to the jQuery selector performance documentation, it's faster to use the two selectors separately, like this:

$('#my_id').find('.my_class')

Here's the relevant part of the documentation:

ID-Based Selectors

// Fast:
$( "#container div.robotarm" );

// Super-fast:
$( "#container" ).find( "div.robotarm" );

The .find() approach is faster because the first selection is handled without going through the Sizzle selector engine – ID-only selections are handled using document.getElementById(), which is extremely fast because it is native to the browser.

Selecting by ID or by class alone (among other things) invokes browser-supplied functions like document.getElementById() which are quite rapid, whereas using a descendent selector invokes the Sizzle engine as mentioned which, although fast, is slower than the suggested alternative.

To delete content without a folder you can use the following:

Remove-Item "foldertodelete\*" -Force -Recurse

For those who have trouble with the accepted solution, there is another way to exclude resource from shaded jar with DontIncludeResourceTransformer:

https://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html#DontIncludeResourceTransformer

          <transformers>
            <transformer implementation="org.apache.maven.plugins.shade.resource.DontIncludeResourceTransformer">
                <resource>BC1024KE.DSA</resource>
            </transformer>
          </transformers>

From Shade 3.0, this transformer accepts a list of resources. Before that you just need to use multiple transformer each with one resource.

 Bitmap yourBitmap;
 Bitmap resized = Bitmap.createScaledBitmap(yourBitmap, newWidth, newHeight, true);

or:

 resized = Bitmap.createScaledBitmap(yourBitmap,(int)(yourBitmap.getWidth()*0.8), (int)(yourBitmap.getHeight()*0.8), true);

Here is the python Version for finding center point. The lat1 and lon1 are latitude and longitude lists. it will retuen the latitude and longitude of center point.

def GetCenterFromDegrees(lat1,lon1):    
    if (len(lat1) <= 0):
    return false;

num_coords = len(lat1)

X = 0.0
Y = 0.0
Z = 0.0

for i in range (len(lat1)):
    lat = lat1[i] * np.pi / 180
    lon = lon1[i] * np.pi / 180

    a = np.cos(lat) * np.cos(lon)
    b = np.cos(lat) * np.sin(lon)
    c = np.sin(lat);

    X += a
    Y += b
    Z += c


X /= num_coords
Y /= num_coords
Z /= num_coords

lon = np.arctan2(Y, X)
hyp = np.sqrt(X * X + Y * Y)
lat = np.arctan2(Z, hyp)

newX = (lat * 180 / np.pi)
newY = (lon * 180 / np.pi)
return newX, newY

Only associative arrays are structs in PHP.

And you can't make them strict on their own.

But you can sort of fake structure strictness with classes and interfaces, but beware that unlike structures, class instances are not passed in arguments, their identifiers are!

You can define a struct through an interface (or at least close to it)

Structs enforce a certain structure on an object.

PHP (<= 7.3) does not have native structs, but you can get around it with interfaces and type hinting:

interface FooStruct 
{
    public function name() : string;
}
interface BarStruct 
{
    public function id() : int;
}
interface MyStruct 
{
   public function foo() : FooStruct;
   public function bar() : BarStruct;
}

Any class implementing MyStruct will be a MyStruct.

The way it's build up is not up to the struct, it just ensures that the data returned is correct.

What about setting data?

Setting struct data is problematic as we end up with getters and setters and it's something that is close to an anemic object or a DTO and is considered an anti-pattern by some people

Wrong example:

interface FooStruct 
{
    public function getName() : string;
    public function setName(string $value) : FooStruct;
}
interface BarStruct 
{
    public function getId() : int;
    public function setId(int $value) : BarStruct;
}
interface MyStruct 
{
   public function getFoo() : FooStruct;
   public function setFoo(FooStruct $value) : MyStruct;
   public function getBar() : BarStruct;
   public function setBar(BarStruct $value) : MyStruct;
}

Then we end up with class implementations that might be mutable, and a struct must not mutate, this is to make it a "data type", just like int, string. Yet there's no way to restrict that with interfaces in PHP, meaning people will be able to implement your struct interface in a class that is not a struct. Make sure to keep the instance immutable

Also a struct may then be instantiated without the correct data and trigger errors when trying to access the data.

An easy and reliable way to set data in a PHP struct class is through its constructor

interface FooStruct 
{
    public function name() : string;
}
interface BarStruct 
{
    public function id() : int;
}
interface MyStruct 
{
   public function foo() : FooStruct;
   public function bar() : BarStruct;
}

class Foo implements FooStruct 
{
   protected $name;
   public function __construct(string $name)
   {
       $this->name = $name;
   }
   public function name() : string
   {
       return $this->name;
   }
}

class Bar implements BarStruct 
{
   protected $id;
   public function __construct(string $id)
   {
       $this->id = $id;
   }
   public function id() : int
   {
       return $this->id;
   }
}

class My implements MyStruct 
{
   protected $foo, $bar;
   public function __construct(FooStruct $foo, BarStruct $bar)
   {
       $this->foo = $foo;
       $this->bar = $bar;
   }
   public function foo() : FooStruct
   {
       return $this->foo;
   }
   public function bar() : BarStruct
   {
       return $this->bar;
   }
}

Type hinting using interfaces: (if your IDE supports it)

If you don't mind not having the strict type checking, then another way would be using interfaces or classes with comments for the IDE.

/**
 * Interface My
 * @property Foo $foo
 * @property Bar $bar
 */
interface My 
{

}

/**
 * Interface Foo
 * @property string|integer $id
 * @property string $name
 */
interface Foo 
{

}

/**
 * Interface Bar
 * @property integer $id
 */
interface Bar
{

}

The reason to use interfaces instead of classes is for the same reason why interfaces exist in the first place, because then many classes with many implementations can have this same structure and each method/function that uses it will support every class with this interface.

This depends on your IDE, so you might need to use classes instead or just live without it.

Note: Remember that you have to validate/sanitize the data in the instance elsewhere in the code to match the comment.

Method 1:\

Method 2: (if method 1 not work then)

simple open command prompt with "run as administrator"

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.

Unfortunately no. The problem here is that the iteration happens inside functions, so they aren't like normal loops. The only way you can "break" out of a function is by returning or by throwing an exception. So yes, using a boolean flag seems to be the only reasonable way to "break" out of the outer "loop".

Try starting MySQL and Apache in Xampp. Verify Port Number assigned to Apache (By default it should be 80). Now load localhost/phpmyadmin. It solved my problem.

Android uses a Java that branches off of Java 6.

As of Android SDK version 19, you can use Java 7 features by doing this. No full support for Java 8 (yet).

If you want to ignore seconds for example you can use

func isDate(Date, equalTo: Date, toUnitGranularity: NSCalendar.Unit) -> Bool

Example compare if it's the same day:

Calendar.current.isDate(date1, equalTo: date2, toGranularity: .day)

My solution, (using jquery):

<iframe id="Iframe1" class="tabFrame" width="100%" height="100%" scrolling="no" src="http://samedomain" frameborder="0" >
</iframe>  
<script type="text/javascript">
    $(function () {

        $('.tabFrame').load(function () {
            var iframeContentWindow = this.contentWindow;
            var height = iframeContentWindow.$(document).height();
            this.style.height = height + 'px';
        });
    });
</script>

Suppose you have multiple project in the solution. Select the project that you want to view in browser and select 'Set as StartUp Project'. In your multiple project soln which was the main, the visual studio was unable to identify. this was the main problem.

Be aware that the path under src/main/resources must match the package path of your .class files wishing to access the resource. See my answer here.

jQuery('.validatedForm').validate({
        rules : {
            password : {
                minlength : 5
            },
            password_confirm : {
                minlength : 5,
                equalTo : '[name="password"]'
            }
        }

In general, you will not use id="password" like this. So, you can use [name="password"] instead of "#password"

Use

 sudo lsof -i:5000

This will give you a list of processes using the port if any. Once the list of processes is given, use the id on the PID column to terminate the process use

 kill 379 #use the provided PID

Maybe I'm being dumb, but isn't table the obvious solution here?

<div class="parent">
    <div class="fixed">
    <div class="stretchToFit">
</div>

.parent{ display: table; width 100%; }
.fixed { display: table-cell; width: 150px; }
.stretchToFit{ display: table-cell; vertical-align: top}

Another way that I've figured out in chrome is even simpler, but man is it a hack!

.fixed{ 
   float: left
}
.stretchToFit{
   display: table-cell;
   width: 1%;
}

This alone should fill the rest of the line horizontally, as table-cells do. However, you get some strange issues with it going over 100% of its parent, setting the width to a percent value fixes it though.

You can also set a Constraint on a Table with the KEY fields and set On Conflict "Ignore"

When an applicable constraint violation occurs, the IGNORE resolution algorithm skips the one row that contains the constraint violation and continues processing subsequent rows of the SQL statement as if nothing went wrong. Other rows before and after the row that contained the constraint violation are inserted or updated normally. No error is returned when the IGNORE conflict resolution algorithm is used.

SQLite Documentation

There is no way to create a file without opening it There is os.mknod("newfile.txt") (but it requires root privileges on OSX). The system call to create a file is actually open() with the O_CREAT flag. So no matter how, you'll always open the file.

So the easiest way to simply create a file without truncating it in case it exists is this:

open(x, 'a').close()

Actually you could omit the .close() since the refcounting GC of CPython will close it immediately after the open() statement finished - but it's cleaner to do it explicitely and relying on CPython-specific behaviour is not good either.

In case you want touch's behaviour (i.e. update the mtime in case the file exists):

import os
def touch(path):
    with open(path, 'a'):
        os.utime(path, None)

You could extend this to also create any directories in the path that do not exist:

basedir = os.path.dirname(path)
if not os.path.exists(basedir):
    os.makedirs(basedir)

I have used the steps in this question and it worked for me.

My issue was that G suite didn't consider my password as strong and after changing it it worked perfectly.

To update just one gem (and it's dependencies), do:

But to update just the gem alone (without updating it's dependencies), do

    bundle update --source gem-name

I don't think there is a way to ignore adding DEFINERs to the dump. But there are ways to remove them after the dump file is created.

1. Open the dump file in a text editor and replace all occurrences of DEFINER=root@localhost with an empty string ""

2. Edit the dump (or pipe the output) using perl:

   perl -p -i.bak -e "s/DEFINER=\`\w.*\`@\`\d[0-3].*[0-3]\`//g" mydatabase.sql
   

3. Pipe the output through sed:

   mysqldump ... | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > triggers_backup.sql
   

You can effectively remove scientific notation in printing with this code:

options(scipen=999)

I've written an Angular directive that does slideToggle() without jQuery.

https://github.com/EricWVGG/AngularSlideables

Go to database, next to title there are 2 options:

Cloud Firestore, Realtime database

Select Realtime database and go to rules

Change rules to true.

$('form').submit(function() {

var el = $(this);

$('<button type="reset" style="display:none; "></button>')
    .appendTo(el)
    .click()
    .remove()
;

return false;

});

On a rooted device, you might use:

String pkg = context.getPackageName();
String shellCmd = "rm -r /data/app/" + pkg + "*.apk\n"
                + "rm -r /data/data/" + pkg + "\n"
                // TODO remove data on the sd card
                + "sync\n"
                + "reboot\n";
Util.sudo(shellCmd);

Util.sudo() is defined here.

For Python 3.8 the correct answer should be:

import more_itertools

d = {'a': 3, 'b': 2, 'c': 3, 'd': 4, 'e': 5}

first_n = more_itertools.take(3, d.items())
print(len(first_n))
print(first_n)

Whose output is:

3
[('a', 3), ('b', 2), ('c', 3)]

After pip install more-itertools of course.

That particular package does not include assemblies for dotnet core, at least not at present. You may be able to build it for core yourself with a few tweaks to the project file, but I can't say for sure without diving into the source myself.

if you want to flip image you can use it.

.image{
    width: 100%;
    -webkit-animation:spin 3s linear infinite;
    -moz-animation:spin 3s linear infinite;
    animation:spin 3s linear infinite;
}

You instruction require call to get, because is it bring the records and orderBy the catalog

$results = Project::orderBy('name')
           ->get();

Example:

$results = Result::where ('id', '>=', '20')
->orderBy('id', 'desc')
->get();

In the example the data is filtered by "where" and bring records greater than 20 and orderBy catalog by order from high to low.

Here is how to get the value of all checked checkboxes as an array:

var values = (function() {
                var a = [];
                $(".checkboxes:checked").each(function() {
                    a.push(this.value);
                });
                return a;
            })()

Use set if you don't care about items order or repetition. Use list comprehensions if you do:

>>> def diff(first, second):
        second = set(second)
        return [item for item in first if item not in second]

>>> diff(A, B)
[1, 3, 4]
>>> diff(B, A)
[5]
>>> 

even shorter if you can lose the yearStart value:

var yearStart = 2000;
var yearEnd = 2040;

var arr = [];

while(yearStart < yearEnd+1){
  arr.push(yearStart++);
}

UPDATE: If you can use the ES6 syntax you can do it the way proposed here:

let yearStart = 2000;
let yearEnd = 2040;
let years = Array(yearEnd-yearStart+1)
    .fill()
    .map(() => yearStart++);

localStorage.clear()

That'll clear the stored data. Then refresh and things should start to work.

Parent-Child communication in VueJS

Given a root Vue instance is accessible by all descendants via this.$root, a parent component can access child components via the this.$children array, and a child component can access it's parent via this.$parent, your first instinct might be to access these components directly.

The VueJS documentation warns against this specifically for two very good reasons:

• It tightly couples the parent to the child (and vice versa)
• You can't rely on the parent's state, given that it can be modified by a child component.

The solution is to use Vue's custom event interface

The event interface implemented by Vue allows you to communicate up and down the component tree. Leveraging the custom event interface gives you access to four methods:

1. $on() - allows you to declare a listener on your Vue instance with which to listen to events
2. $emit() - allows you to trigger events on the same instance (self)

Example using $on() and $emit():

const events = new Vue({}),_x000D_
    parentComponent = new Vue({_x000D_
      el: '#parent',_x000D_
      ready() {_x000D_
        events.$on('eventGreet', () => {_x000D_
          this.parentMsg = `I heard the greeting event from Child component ${++this.counter} times..`;_x000D_
        });_x000D_
      },_x000D_
      data: {_x000D_
        parentMsg: 'I am listening for an event..',_x000D_
        counter: 0_x000D_
      }_x000D_
    }),_x000D_
    childComponent = new Vue({_x000D_
      el: '#child',_x000D_
      methods: {_x000D_
      greet: function () {_x000D_
        events.$emit('eventGreet');_x000D_
        this.childMsg = `I am firing greeting event ${++this.counter} times..`;_x000D_
      }_x000D_
    },_x000D_
    data: {_x000D_
      childMsg: 'I am getting ready to fire an event.',_x000D_
      counter: 0_x000D_
    }_x000D_
  });

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.28/vue.min.js"></script>_x000D_
_x000D_
<div id="parent">_x000D_
  <h2>Parent Component</h2>_x000D_
  <p>{{parentMsg}}</p>_x000D_
</div>_x000D_
_x000D_
<div id="child">_x000D_
  <h2>Child Component</h2>_x000D_
  <p>{{childMsg}}</p>_x000D_
  <button v-on:click="greet">Greet</button>_x000D_
</div>

Answer taken from the original post: Communicating between components in VueJS

As Kintaro already says, person is a method (because of def) and always returns a new Person instance. As you found out it would work if you change the method to a var or val:

val person = new Person("Kumar",12)

Another possibility would be:

def person = new Person("Kumar",12)
val p = person
p.age=20
println(p.age)

However, person.age=20 in your code is allowed, as you get back a Person instance from the person method, and on this instance you are allowed to change the value of a var. The problem is, that after that line you have no more reference to that instance (as every call to person will produce a new instance).

This is nothing special, you would have exactly the same behavior in Java:

class Person{ 
   public int age; 
   private String name;
   public Person(String name; int age) {
      this.name = name;  
      this.age = age;
   }
   public String name(){ return name; }
}

public Person person() { 
  return new Person("Kumar", 12); 
}

person().age = 20;
System.out.println(person().age); //--> 12

geonames.org has an api and a data dump of worldwide geographical places.

Curl is a non-java program and must be provided outside your Java program.

You can easily get much of the functionality using Jakarta Commons Net, unless there is some specific functionality like "resume transfer" you need (which is tedious to code on your own)

print(data)
print(arrData.size)
print(arrData.shape)

Output

[[1, 2, 3, 4], [5, 6, 7, 8]]

freopen solves the easy part. Keeping old stdin around is not hard if you haven't read anything and if you're willing to use POSIX system calls like dup or dup2. If you're started to read from it, all bets are off.

Maybe you can tell us the context in which this problem occurs?

I'd encourage you to stick to situations where you're willing to abandon old stdin and stdout and can therefore use freopen.

Any uncomitted transaction will leave the server locked and other queries won't execute on the server. You either need to rollback the transaction or commit it. Closing out of SSMS will also terminate the transaction which will allow other queries to execute.

To read a whole line from a file into a string, use std::getline like so:

 std::ifstream file("my_file");
 std::string temp;
 std::getline(file, temp);

You can do this in a loop to until the end of the file like so:

 std::ifstream file("my_file");
 std::string temp;
 while(std::getline(file, temp)) {
      //Do with temp
 }

This actually sums it up pretty nicely.

API Levels generally mean that as a programmer, you can communicate with the devices' built in functions and functionality. As the API level increases, functionality adds up (although some of it can get deprecated).

Choosing an API level for an application development should take at least two thing into account:

1. Current distribution - How many devices can actually support my application, if it was developed for API level 9, it cannot run on API level 8 and below, then "only" around 60% of devices can run it (true to the date this post was made).
2. Choosing a lower API level may support more devices but gain less functionality for your app. you may also work harder to achieve features you could've easily gained if you chose higher API level.

Android API levels can be divided to five main groups (not scientific, but what the heck):

1. Android 1.5 - 2.3 (Cupcake to Gingerbread) - (API levels 3-10) - Android made specifically for smartphones.
2. Android 3.0 - 3.2 (Honeycomb) (API levels 11-13) - Android made for tablets.
3. Android 4.0 - 4.4 (KitKat) - (API levels 14-19) - A big merge with tons of additional functionality, totally revamped Android version, for both phone and tablets.
4. Android 5.0 - 5.1 (Lollipop) - (API levels 21-22) - Material Design introduced.
5. Android 6.0 - 6.… (Marshmallow) - (API levels 23-…) - Runtime Permissions,Apache HTTP Client Removed

I ran into the same issue, but I think it was due to spring caching some gems and configurations. I fixed it by running gem pristine --all.

This restores installed gems to pristine condition from files located in the gem cache.

or you can just try for your gem like

gem pristine your_gem_name

In addition to previous post you can have

<h:form rendered="#{!bean.boolvalue}" />
<h:form rendered="#{bean.textvalue == 'value'}" />

In python add the following lines to get a time stamp:

 If strMyString.Tostring.Contains("Something") or strMyString.Tostring.Contains("Something2") Then


     End if

If the caption box is gray then you can try wrapping the image and the caption in a div with the same background color of gray---so a "div" tag before the "tr" tag...This will mask the gap because instead of being white, it will be gray and look like part of the gray caption.

You can see the move operation on push_back and not on emplace_back.

The default port for SQL Server Database Engine is 1433.

And as a best practice it should always be changed after the installation. 1433 is widely known which makes it vulnerable to attacks.

I tried all the possible commands listed above and none of them worked for me, Check if Package.json contain "@angular-devkit/build-angular" if not just install it using(in my case version 0.803.19 worked)

npm i @angular-devkit/[email protected]

Or checkout at npm website repositories for version selection

You can do it using only grep by:

1. reading the file line by line
2. matching a pattern in each line and highlighting pattern by grep
3. if there is no match, echo the line as is

which gives you the following:

while read line ; do (echo $line | grep PATTERN) || echo $line  ; done < inputfile

You use new to perform dynamic allocation. It returns a pointer that points to the dynamically allocated object.

You have no reason to use new, since A is an automatic variable. You can simply initialise A using its constructor:

vector<vector<int> > A(dimension, vector<int>(dimension));

I don't know MSSQL but would it not be:

Have you enabled 'unknown sources' from security and restrictions settings?

from django.http import QueryDict

def search(request):

Use this way, django offical document recommended __contains__ method. See https://docs.djangoproject.com/en/1.9/ref/request-response/

This solution is based on @SkyLeach answer but with the support of dropping tables with foreign keys.

echo "SET FOREIGN_KEY_CHECKS = 0;" > ./drop_all_tables.sql
mysqldump --add-drop-table --no-data -u user -p dbname | grep 'DROP TABLE' >> ./drop_all_tables.sql
echo "SET FOREIGN_KEY_CHECKS = 1;" >> ./drop_all_tables.sql
mysql -u user -p dbname < ./drop_all_tables.sql

The OP did not exclude the starting variable, so for completeness here is how to handle the generic case of processing a supposed dictionary that may include items as dictionaries.

Also following the pure Python(3.8) recommended way to test for dictionary in the above comments.

from collections.abc import Mapping

dict = {'abc': 'abc', 'def': {'ghi': 'ghi', 'jkl': 'jkl'}}

def parse_dict(in_dict): 
    if isinstance(in_dict, Mapping):
        for k_outer, v_outer in in_dict.items():
            if isinstance(v_outer, Mapping):
                for k_inner, v_inner in v_outer.items():
                    print(k_inner, v_inner)
            else:
                print(k_outer, v_outer)

parse_dict(dict)

You can also do this with ant contrib's if task.

<if>
    <equals arg1="${condition}" arg2="true"/>
    <then>
        <copy file="${some.dir}/file" todir="${another.dir}"/>
    </then>
    <elseif>
        <equals arg1="${condition}" arg2="false"/>
        <then>
            <copy file="${some.dir}/differentFile" todir="${another.dir}"/>
        </then>
    </elseif>
    <else>
        <echo message="Condition was neither true nor false"/>
    </else>
</if>

It depends a bit on what you want:

A) If you want to specify which libraries to link to, you can use find_library to find libs and then use link_directories and target_link_libraries to.

Of course, it is often worth the effort to write a good find_package script, which nicely adds "imported" libraries with add_library( YourLib IMPORTED ) with correct locations, and platform/build specific pre- and suffixes. You can then simply refer to 'YourLib' and use target_link_libraries.

B) If you wish to specify particular linker-flags, e.g. '-mthreads' or '-Wl,--export-all-symbols' with MinGW-GCC, you can use CMAKE_EXE_LINKER_FLAGS. There are also two similar but undocumented flags for modules, shared or static libraries:

CMAKE_MODULE_LINKER_FLAGS
CMAKE_SHARED_LINKER_FLAGS
CMAKE_STATIC_LINKER_FLAGS

do it with the following code:

DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();

    try {
        DocumentBuilder builder = builderFactory.newDocumentBuilder();
        Document doc = builder.parse("/home/codefelix/IdeaProjects/Gradle/src/main/resources/static/Employees.xml");
        NodeList namelist = (NodeList) doc.getElementById("1");

        for (int i = 0; i < namelist.getLength(); i++) {
            Node p = namelist.item(i);

            if (p.getNodeType() == Node.ELEMENT_NODE) {
                Element person = (Element) p;
                NodeList id = (NodeList) person.getElementsByTagName("Employee");
                NodeList nodeList = person.getChildNodes();
                List<EmployeeDto> employeeDtoList=new ArrayList();

                for (int j = 0; j < nodeList.getLength(); j++) {
                    Node n = nodeList.item(j);

                    if (n.getNodeType() == Node.ELEMENT_NODE) {
                        Element naame = (Element) n;
                        System.out.println("Employee" + id + ":" + naame.getTagName() + "=" +naame.getTextContent());
                    }
                }
            }
        }
    } catch (ParserConfigurationException e) {
        e.printStackTrace();
    } catch (SAXException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

}

There is not a way to directly get the version out, but there are two work-arounds that could be done.

1. The version could be stored in a resource string, and placed into the manifest by:

   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.somepackage"
        android:versionName="@string/version" android:versionCode="20">
   

2. One could create a custom view, and place it into the XML. The view would use this to assign the name:

   context.getPackageManager().getPackageInfo(context.getPackageName(), 0).versionName;
   

Either of these solutions would allow for placing the version name in XML. Unfortunately there isn't a nice simple solution, like android.R.string.version or something like that.

Yes you can (provided you have at least the professional version of visual studio), although it requires a little setting up once you've done this it's not much different from debugging code. MSDN has a basic walkthrough.

I wonder why String.prototype.concat is not getting any love. In my tests (assuming you already have an array of strings), it outperforms all other methods.

perf.link test

Test code:

const numStrings = 100;
const strings = [...new Array(numStrings)].map(() => Math.random().toString(36).substring(6));

const concatReduce = (strs) => strs.reduce((a, b) => a + b);

const concatLoop = (strs) => {
  let result = ''
  for (let i = 0; i < strings.length; i++) {
    result += strings[i];
  }
  return result;
}

// Case 1: 52,570 ops/s
concatLoop(strings);

// Case 2: 96,450 ops/s
concatReduce(strings)

// Case 3: 138,020 ops/s
strings.join('')

// Case 4: 169,520 ops/s
''.concat(...strings)

you could use it like this :

  $('#formId').submit();

OR

document.formName.submit();

Check as @joyfun did for the correct version of jackson but also check our headers ... Accept / may not be transmitted by the client ... use firebug or equivalent to check what your get request is actually sending. I think the headers attribute of the annotation /may/ be checking literals although I'm not 100% sure.

For what it's worth, I had a similar issue ng-cloak not working. It may be worth checking your app/site with cache enabled to reuse source files to see if that helps.

With my run-in with flickering, I was testing with DevTools open and cache disabled. Leaving the panel closed with caching enabled fixed my issue.

Because git has the cool ability to push/pull different branches to different "upstream" repositories. You could even use separate repositories for pushing and pulling - on the same branch. This can create a distributed, multi-level flow, I can see this being useful on project such as the Linux kernel. Git was originally built to be used on that project.

As a consequence, it does not make assumption about which repo your branch should be tracking.

On the other hand, most people do not use git in this way, so it might make a good case for a default option.

Git is generally pretty low-level and it can be frustrating. Yet there are GUIs and it should be easy to write helper scripts if you still want to use it from the shell.

This works:

@media not all and (min-resolution:.001dpcm) { 
  @media {
    /* your code for Safari Desktop & Mobile */
    body {

      color: blue;
    }
    /* end */
  }
}

The answer of Shyam was right. I already faced with this issue before. It's not a problem, it's a SPRING feature. "Transaction rolled back because it has been marked as rollback-only" is acceptable.

Conclusion

• USE REQUIRES_NEW if you want to commit what did you do before exception (Local commit)
• USE REQUIRED if you want to commit only when all processes are done (Global commit) And you just need to ignore "Transaction rolled back because it has been marked as rollback-only" exception. But you need to try-catch out side the caller processNextRegistrationMessage() to have a meaning log.

Let's me explain more detail:

Question: How many Transaction we have? Answer: Only one

Because you config the PROPAGATION is PROPAGATION_REQUIRED so that the @Transaction persist() is using the same transaction with the caller-processNextRegistrationMessage(). Actually, when we get an exception, the Spring will set rollBackOnly for the TransactionManager so the Spring will rollback just only one Transaction.

Question: But we have a try-catch outside (), why does it happen this exception? Answer Because of unique Transaction

1. When persist() method has an exception

2. Go to the catch outside

   Spring will set the rollBackOnly to true -> it determine we must 
   rollback the caller (processNextRegistrationMessage) also.
   

3. The persist() will rollback itself first.

4. Throw an UnexpectedRollbackException to inform that, we need to rollback the caller also.
5. The try-catch in run() will catch UnexpectedRollbackException and print the stack trace

Question: Why we change PROPAGATION to REQUIRES_NEW, it works?

Answer: Because now the processNextRegistrationMessage() and persist() are in the different transaction so that they only rollback their transaction.

.gitkeep isn’t documented, because it’s not a feature of Git.

Git cannot add a completely empty directory. People who want to track empty directories in Git have created the convention of putting files called .gitkeep in these directories. The file could be called anything; Git assigns no special significance to this name.

There is a competing convention of adding a .gitignore file to the empty directories to get them tracked, but some people see this as confusing since the goal is to keep the empty directories, not ignore them; .gitignore is also used to list files that should be ignored by Git when looking for untracked files.

I noticed huge memory leak & performance difference between insertAfter & after or insertBefore & before .. If you have tons of DOM elements, or you need to use after() or before() inside a MouseMove event, the browser memory will probably increase and next operations will run really slow.

The solution I've just experienced is to use inserBefore instead before() and insertAfter instead after().

I am late for this but i want put some more solution relevant to this.

Thanks for the idea of breaking down a formula Werner!

Using Alt+Enter allows one to put each bit of a complex substitute formula on separate lines: they become easier to follow and automatically line themselves up when Enter is pressed.

Just make sure you have enough end statements to match the number of substitute( lines either side of the cell reference.

As in this example:

=
substitute(
substitute(
substitute(
substitute(
B11
,"(","")
,")","")
,"[","")
,"]","")

becomes:

=
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(B12,"(",""),")",""),"[",""),"]","")

which works fine as is, but one can always delete the extra paragraphs manually:

=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(B12,"(",""),")",""),"[",""),"]","")

Name > substitute()

Just change + to -:

str = str.replace(/[^a-z0-9-]/g, "");

You can read it as:

1. [^ ]: match NOT from the set
2. [^a-z0-9-]: match if not a-z, 0-9 or -
3. / /g: do global match

You could go into the designer of the web form and change the "webcontrols" to be "public" instead of "protected" but I'm not sure how safe that is. I prefer to make hidden inputs and have some jQuery set the values into those hidden inputs, then create public properties in the web form's class (code behind), and access the values that way.

We had a similar issue. Uploaded builds were queueing up and it simply said "Processing" with the popup help, “After builds are uploaded they will go through a processing state before they can be used.” Days passed.

Selecting "Internal Testers," making a change, and saving seemed to immediately clear the queue: The latest build was now active and available for testing. I've done this twice with two different apps now.

Update: At this point, all bets are off. It seems "processing" happens when Apple quietly upgrades iTunes Connect and there's nothing you can do about it.

On September 23, 2015 iTunes Connect didn't accept any uploads for nearly 24 hours. The "Internal Testers" trick didn't work. Eventually bumping the version number (to avoid "duplicate binary" error) and re-submitting worked.

The next day, Surprise! iTunes Connect was completely changed. I guess we were all looking at a dead site while they brought up the new version in the background :(

In our case we can still see dozens of "failed" uploads still sitting in the "processing" state. Oh well.

Some people report using Application Loader works better than Xcode for submitting builds to iTunes Connect. You can find it inside Xcode now, under the Xcode menu "Open Developer Tool" item.

Sometimes this works. Sometimes it doesn't. Your milage may vary ¯\_(?)_/¯

I have a Fascinate as well, and had to change the phone's USB communication mode from MODEM to PDA. Use:

• enter **USBUI (**87284)

to change both USB and UART to PDA mode. I also had to disconnect and reconnect the USB cable. Once Windows re-recognized the device again, "adb devices" started returning my device.

BTW if you use CDMA workshop or the equivalent, you will need to switch the setting back to MODEM.

You can suppress the new line by using the set /p command. The set /p command does not recognize a space, for that you can use a dot and a backspace character to make it recognize it. You can also use a variable as a memory and store what you want to print in it, so that you can print the variable instead of the sentence. For example:

@echo off
setlocal enabledelayedexpansion
for /f %%a in ('"prompt $H & for %%b in (1) do rem"') do (set "bs=%%a")
cls
set "var=Hello World! :)"
set "x=0"

:loop
set "display=!var:~%x%,1!"
<nul set /p "print=.%bs%%display%"
ping -n 1 localhost >nul
set /a "x=%x% + 1"
if "!var:~%x%,1!" == "" goto end
goto loop

:end
echo.
pause
exit

In this way you can print anything without a new line. I have made the program to print the characters one by one, but you can use words too instead of characters by changing the loop.

In the above example I used "enabledelayedexpansion" so the set /p command does not recognize "!" character and prints a dot instead of that. I hope that you don't have the use of the exclamation mark "!" ;)

Change detection

Only @Component can be a node in the change detection tree. This means that you cannot set ChangeDetectionStrategy.OnPush in a @Directive. Despite this fact, a Directive can have @Input and @Output properties and you can inject and manipulate host component's ChangeDetectorRef from it. So use Components when you need a granular control over your change detection tree.

If you are on python 3.3 or above then it already has a built-in function for computing log2(x)

import math
'finds log base2 of x'
answer = math.log2(x)

If you are on older version of python then you can do like this

import math
'finds log base2 of x'
answer = math.log(x)/math.log(2)

One other way, using the splat operator:

*a, last = [1, 3, 4, 5]

STDOUT:
a: [1, 3, 4]
last: 5

Having a "table" in memory that needs lookups, sorting, and arbitrary aggregation really does call out for SQL. You said you tried SQLite, but did you realize that SQLite can use an in-memory-only database?

connection = sqlite3.connect(':memory:')

Then you can create/drop/query/update tables in memory with all the functionality of SQLite and no files left over when you're done. And as of Python 2.5, sqlite3 is in the standard library, so it's not really "overkill" IMO.

Here is a sample of how one might create and populate the database:

import csv
import sqlite3

db = sqlite3.connect(':memory:')

def init_db(cur):
    cur.execute('''CREATE TABLE foo (
        Row INTEGER,
        Name TEXT,
        Year INTEGER,
        Priority INTEGER)''')

def populate_db(cur, csv_fp):
    rdr = csv.reader(csv_fp)
    cur.executemany('''
        INSERT INTO foo (Row, Name, Year, Priority)
        VALUES (?,?,?,?)''', rdr)

cur = db.cursor()
init_db(cur)
populate_db(cur, open('my_csv_input_file.csv'))
db.commit()

If you'd really prefer not to use SQL, you should probably use a list of dictionaries:

lod = [ ] # "list of dicts"

def populate_lod(lod, csv_fp):
    rdr = csv.DictReader(csv_fp, ['Row', 'Name', 'Year', 'Priority'])
    lod.extend(rdr)

def query_lod(lod, filter=None, sort_keys=None):
    if filter is not None:
        lod = (r for r in lod if filter(r))
    if sort_keys is not None:
        lod = sorted(lod, key=lambda r:[r[k] for k in sort_keys])
    else:
        lod = list(lod)
    return lod

def lookup_lod(lod, **kw):
    for row in lod:
        for k,v in kw.iteritems():
            if row[k] != str(v): break
        else:
            return row
    return None

Testing then yields:

>>> lod = []
>>> populate_lod(lod, csv_fp)
>>> 
>>> pprint(lookup_lod(lod, Row=1))
{'Name': 'Cat', 'Priority': '1', 'Row': '1', 'Year': '1998'}
>>> pprint(lookup_lod(lod, Name='Aardvark'))
{'Name': 'Aardvark', 'Priority': '1', 'Row': '4', 'Year': '2000'}
>>> pprint(query_lod(lod, sort_keys=('Priority', 'Year')))
[{'Name': 'Cat', 'Priority': '1', 'Row': '1', 'Year': '1998'},
 {'Name': 'Dog', 'Priority': '1', 'Row': '3', 'Year': '1999'},
 {'Name': 'Aardvark', 'Priority': '1', 'Row': '4', 'Year': '2000'},
 {'Name': 'Wallaby', 'Priority': '1', 'Row': '5', 'Year': '2000'},
 {'Name': 'Fish', 'Priority': '2', 'Row': '2', 'Year': '1998'},
 {'Name': 'Zebra', 'Priority': '3', 'Row': '6', 'Year': '2001'}]
>>> pprint(query_lod(lod, sort_keys=('Year', 'Priority')))
[{'Name': 'Cat', 'Priority': '1', 'Row': '1', 'Year': '1998'},
 {'Name': 'Fish', 'Priority': '2', 'Row': '2', 'Year': '1998'},
 {'Name': 'Dog', 'Priority': '1', 'Row': '3', 'Year': '1999'},
 {'Name': 'Aardvark', 'Priority': '1', 'Row': '4', 'Year': '2000'},
 {'Name': 'Wallaby', 'Priority': '1', 'Row': '5', 'Year': '2000'},
 {'Name': 'Zebra', 'Priority': '3', 'Row': '6', 'Year': '2001'}]
>>> print len(query_lod(lod, lambda r:1997 <= int(r['Year']) <= 2002))
6
>>> print len(query_lod(lod, lambda r:int(r['Year'])==1998 and int(r['Priority']) > 2))
0

Personally I like the SQLite version better since it preserves your types better (without extra conversion code in Python) and easily grows to accommodate future requirements. But then again, I'm quite comfortable with SQL, so YMMV.

Actually, the jQuery documentation has a more simple approach than the chained examples shown above (although they'll work just fine):

$("#myElement").unbind('mouseenter mouseleave');

As of jQuery 1.7, you are also able use $.on() and $.off() for event binding, so to unbind the hover event, you would use the simpler and tidier:

$('#myElement').off('hover');

The pseudo-event-name "hover" is used as a shorthand for "mouseenter mouseleave" but was handled differently in earlier jQuery versions; requiring you to expressly remove each of the literal event names. Using $.off() now allows you to drop both mouse events using the same shorthand.

Edit 2016:

Still a popular question so it's worth drawing attention to @Dennis98's point in the comments below that in jQuery 1.9+, the "hover" event was deprecated in favour of the standard "mouseenter mouseleave" calls. So your event binding declaration should now look like this:

$('#myElement').off('mouseenter mouseleave');

You can use ngHide (or ngShow) directive. It doesn't create child scope as ngIf does.

<div ng-hide="testa">

2. Opened the Python 3.6.5 and typed in nltk.download().The download graphic window opened and all the packages got installed.

Here's the most concise way I've found (using capybara 3.3.0 and chromium driver):

all('#id-of-select option')[1].select_option

will select the 2nd option. Increment the index as needed.

I fix it by brew install libpng

You can setup SSH key authorization like described here - https://confluence.atlassian.com/bitbucket/add-an-ssh-key-to-an-account-302811853.html.

You shouldn't design your application based on specific lifetimes of access tokens. Just assume they are (very) short lived.

However, after a successful completion of the OAuth2 installed application flow, you will get back a refresh token. This refresh token never expires, and you can use it to exchange it for an access token as needed. Save the refresh tokens, and use them to get access tokens on-demand (which should then immediately be used to get access to user data).

EDIT: My comments above notwithstanding, there are two easy ways to get the access token expiration time:

1. It is a parameter in the response (expires_in)when you exchange your refresh token (using /o/oauth2/token endpoint). More details.

2. There is also an API that returns the remaining lifetime of the access_token:

   https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={accessToken}

   This will return a json array that will contain an expires_in parameter, which is the number of seconds left in the lifetime of the token.

You can use pointer-events: none; in your CSS

div {
  pointer-events: none;
}

This function check the special chars on key press and eliminates the value if it is not a number

function mobilevalid(id) {

    var feild = document.getElementById(id);

    if (isNaN(feild.value) == false) {
        if (feild.value.length == 1) {
            if (feild.value < 7) {
                feild.value = "";
            }
        } else if (feild.value.length > 10) {
            feild.value = feild.value.substr(0, feild.value.length - 1);
        }
        if (feild.value.charAt(0) < 7) {
            feild.value = "";
        }
    } else {
        feild.value = "";
    }

}

One more possibility --

Make sure you're trying to open the same IP address as where you're listening. My server app was listening to the host machine's IP address using IPv6, but the client was attempting to connect on the host machine's IPv4 address.

Position the element as relative and then use z-index, it worked for me :)

Insert a new verse after the given verse in your stanza:

I also put an answer there, but the article @Colonel Panic's update refers to suggests forcing TLS 1.2. In the future, when TLS 1.2 is compromised or just superceded, having your code stuck to TLS 1.2 will be considered a deficiency. Negotiation to TLS1.2 is enabled in .Net 4.6 by default. If you have the option to upgrade your source to .Net 4.6, I would highly recommend that change over forcing TLS 1.2.

If you do force TLS 1.2, strongly consider leaving some type of breadcrumb that will remove that force if you do upgrade to the 4.6 or higher framework.

A link with 1 function defined

<a href="#" onclick="someFunc()">Click me To fire some functions</a>

Firing multiple functions from someFunc()

function someFunc() {
    showAlert();
    validate();
    anotherFunction();
    YetAnotherFunction();
}

It appears to be working fine for mm/dd/yyyy format dates, example:

http://jsfiddle.net/niklasvh/xfrLm/

The only problem I had with your code was the fact that:

var ExpiryDate = document.getElementById(' ExpiryDate').value;

Had a space inside the brackets, before the element ID. Changed it to:

var ExpiryDate = document.getElementById('ExpiryDate').value;

Without any further details regarding the type of data that isn't working, there isn't much else to give input on.

Update

As the Answer below is now somewhat outdated, I'd just draw attention to the readxl package. If the Excel sheet is well formatted/lain out then I would now use readxl to read from the workbook. If sheets are poorly formatted/lain out then I would still export to CSV and then handle the problems in R either via read.csv() or plain old readLines().

Original

My preferred way is to save individual Excel sheets in comma separated value (CSV) files. On Windows, these files are associated with Excel so you don't loose the double-click-open-in-Excel "feature".

CSV files can be read into R using read.csv(), or, if you are in a location or using a computer set up with some European settings (where , is used as the decimal place), using read.csv2().

These functions have sensible defaults that makes reading appropriately formatted files simple. Just keep any labels for samples or variables in the first row or column.

Added benefits of storing files in CSV are that as the files are plain text they can be passed around very easily and you can be confident they will open anywhere; one doesn't need Excel to look at or edit the data.

You should try delimit it can open up to 2 billion rows and 2 million columns very quickly has a free 15 day trial too. Does the job for me!

Use below code to get all attributes with details

    global $wpdb;

    $attribute_taxonomies = $wpdb->get_results( "SELECT * FROM " . $wpdb->prefix . "woocommerce_attribute_taxonomies WHERE attribute_name != '' ORDER BY attribute_name ASC;" );
    set_transient( 'wc_attribute_taxonomies', $attribute_taxonomies );

    $attribute_taxonomies = array_filter( $attribute_taxonomies  ) ;

    prin_r($attribute_taxonomies);

you have following errors which in turn is causing you that exception, let me explain it

this is your existing code:

if(!scan.hasNextInt()) {
        System.out.println("Invalid input!");
        System.out.print("Enter an integer: ");
        usrInput= sc.nextInt();
    }

in the above code if(!scan.hasNextInt()) will become true only when user input contains both characters as well as integers like your input adfd 123.

but you are trying to read only integers inside the if condition using usrInput= sc.nextInt();. Which is incorrect,that's what is throwing Exception in thread "main" java.util.InputMismatchException.

so correct code should be

 if(!scan.hasNextInt()) {
            System.out.println("Invalid input!");
            System.out.print("Enter an integer: ");
            sc.next(); 
            continue;
        }

in the above code sc.next() will help to read new input from user and continue will help in executing same if condition(i.e if(!scan.hasNextInt())) again.

Please use code in my first answer to build your complete logic.let me know if you need any explanation on it.

If you're just using formOptions to pick a single value and then close, Mitch's suggestion is a good way to go. My example here would be used if you needed the child to communicate back to the parent while remaining open.

In your parent form, add a public method that the child form will call, such as

public void NotifyMe(string s)
{
    // Do whatever you need to do with the string
}

Next, when you need to launch the child window from the parent, use this code:

using (FormOptions formOptions = new FormOptions())
{
    // passing this in ShowDialog will set the .Owner 
    // property of the child form
    formOptions.ShowDialog(this);
}

In the child form, use this code to pass a value back to the parent:

ParentForm parent = (ParentForm)this.Owner;
parent.NotifyMe("whatever");

The code in this example would be better used for something like a toolbox window which is intended to float above the main form. In this case, you would open the child form (with .TopMost = true) using .Show() instead of .ShowDialog().

A design like this means that the child form is tightly coupled to the parent form (since the child has to cast its owner as a ParentForm in order to call its NotifyMe method). However, this is not automatically a bad thing.

Its just that you need multiple When for a single case to behave it like if.. Elseif else..

   Case when 1=1       //if
   Then
    When 1=1              //else if
     Then.... 
    When .....              //else if
    Then 
    Else                      //else
   ....... 
     End

Note and update:

Since Git1.7.4 (January 2011), you have git merge --abort, synonymous to "git reset --merge" when a merge is in progress.

But if you want to complete the merge, while somehow nothing remains to be added, then a crude rm -rf .git/MERGE* can be enough for Git to forget about the current merge.

For Ubntu Users

 1. Install compilers
    #sudo apt-get install make
    #sudo apt-get install gcc

    2. Install openssl and development libraries
    #sudo apt-get install openssl
    #sudo apt-get install libssl-dev
    3. Install the APR package (Downloaded from http://apr.apache.org/)

    #tar -xzf apr-1.4.6.tar.gz
    #cd apr-1.4.6/
    #sudo ./configure
    #sudo make
    #sudo make install

    You should see the compiled file as
    /usr/local/apr/lib/libapr-1.a

    4. Download, compile and install Tomcat Native sourse package
    tomcat-native-1.1.27-src.tar.gz

    Extract the archive into some folder

    #tar -xzf tomcat-native-1.1.27-src.tar.gz
    #cd tomcat-native-1.1.27-src/jni/native
    #JAVA_HOME=/usr/lib/jvm/jdk1.7.0_21/
    #sudo ./configure --with-apr=/usr/local/apr --with-java-home=$JAVA_HOME
    #sudo make
    #sudo make install

    Now I have compiled Tomcat Native library in /usr/local/apr/libtcnative-1.so.0.1.27 and symbolic link file /usr/local/apr/@libtcnative-1.so pointed to the library

    5. Create or edit the $CATALINA_HOME/bin/setenv.sh file with following lines :
    export LD_LIBRARY_PATH='$LD_LIBRARY_PATH:/usr/local/apr/lib'

    6. Restart tomcat and see the desired result:

parseInt is misfeatured like scanf:

parseInt("12 monkeys", 10) is a number with value '12'
+"12 monkeys"              is a number with value 'NaN'
Number("12 monkeys")       is a number with value 'NaN'

I was facing this issue while deploying my ear to my local weblogic instance. Clearing the local repository and building the ear again resolved the issue for me.

If you cannot use spark-csv, you can do the following:

df.rdd.map(lambda x: ",".join(map(str, x))).coalesce(1).saveAsTextFile("file.csv")

If you need to handle strings with linebreaks or comma that will not work. Use this:

import csv
import cStringIO

def row2csv(row):
    buffer = cStringIO.StringIO()
    writer = csv.writer(buffer)
    writer.writerow([str(s).encode("utf-8") for s in row])
    buffer.seek(0)
    return buffer.read().strip()

df.rdd.map(row2csv).coalesce(1).saveAsTextFile("file.csv")

MERGE doesn't need "multiple tables", but it does need a query as the source. Something like this should work:

MERGE INTO mytable d
USING (SELECT 1 id, 'x' name from dual) s
ON (d.id = s.id)
WHEN MATCHED THEN UPDATE SET d.name = s.name
WHEN NOT MATCHED THEN INSERT (id, name) VALUES (s.id, s.name);

Alternatively you can do this in PL/SQL:

BEGIN
  INSERT INTO mytable (id, name) VALUES (1, 'x');
EXCEPTION
  WHEN DUP_VAL_ON_INDEX THEN
    UPDATE mytable
    SET    name = 'x'
    WHERE id = 1;
END;

Yes, underscores may be used anywhere in an identifier. I believe the rules are: any of a-z, A-Z, _ in the first character and those +0-9 for the following characters.

Underscore prefixes are common in C code -- a single underscore means "private", and double underscores are usually reserved for use by the compiler.

Though it may be unrelated to your question, take a look at GetGUIThreadInfo Function.

Off hand, setting the http.agent system property to "" might do the trick (I don't have the code in front of me).

You might get away with:

 System.setProperty("http.agent", "");

but that might require a race between you and initialisation of the URL protocol handler, if it caches the value at startup (actually, I don't think it does).

The property can also be set through JNLP files (available to applets from 6u10) and on the command line:

-Dhttp.agent=

Or for wrapper commands:

-J-Dhttp.agent=

None of the 'overflow' solutions worked for me. I'm coding a parallax effect with JavaScript using jQuery. In Chrome and Safari on OSX the elastic/rubber-band effect was messing up my scroll numbers, since it actually scrolls past the document's height and updates the window variables with out-of-boundary numbers. What I had to do was check if the scrolled amount was larger than the actual document's height, like so:

$(window).scroll(
    function() {
        if ($(window).scrollTop() + $(window).height() > $(document).height()) return;
        updateScroll(); // my own function to do my parallaxing stuff
    }
);

Read this section of Laravel doc : http://laravel.com/docs/eloquent#mass-assignment

Laravel provides by default a protection against mass assignment security issues. That's why you have to manually define which fields could be "mass assigned" :

class User extends Model
{
    protected $fillable = ['username', 'email', 'password'];
}

Warning : be careful when you allow the mass assignment of critical fields like password or role. It could lead to a security issue because users could be able to update this fields values when you don't want to.

There are many different things you can do when dealing with responsive tables.

I personally like this approach by Chris Coyier:

• http://css-tricks.com/responsive-data-tables/

You can find many other alternatives here:

• http://css-tricks.com/responsive-data-table-roundup/
• http://bradfrost.github.io/this-is-responsive/patterns.html#tables

If you can leverage Bootstrap and get something quickly, you can simply use the class names ".hidden-phone" and ".hidden-tablet" to hide some rows but this approach might to be the best in many cases. More info (see "Responsive utility classes"):

• http://twitter.github.io/bootstrap/scaffolding.html#responsive

Try this instead:

print_r($sth->errorInfo());

Add this before your prepare:

$this->pdo->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING );

This will change the PDO error reporting type and cause it to emit a warning whenever there is a PDO error. It should help you track it down, although your errorInfo should have bet set.

Additionally, if you're building a ReSTful API, browser leakage and http referer issues are mostly mitigated as the client may not be a browser and you may not have people clicking links.

If this is the case I'd recommend oAuth2 login to obtain a bearer token. In which case the only sensitive data would be the initial credentials...which should probably be in a post request anyway

Use the atexit module of Python's standard library to register "termination" functions that get called (on the main thread) on any reasonably "clean" termination of the main thread, including an uncaught exception such as KeyboardInterrupt. Such termination functions may (though inevitably in the main thread!) call any stop function you require; together with the possibility of setting a thread as daemon, that gives you the tools to properly design the system functionality you need.

If you have not committed any changes all you have to do is stash those changes and you will be back to the last working commit.

git stash
git stash clear
git clean 

Because growthRates is a sequence (you're even iterating it!) and you multiply it by (1 + 0.01), which is obviously a float (1.01). I guess you mean for growthRate in growthRates: ... * growthrate?

Use the following code:

if(processing == success) {
  header("Location:filename");
  exit();
}

And you are good to go.

You should use this:

<Link to={this.props.myroute} onClick={hello}>Here</Link>

Or (if method hello lays at this class):

<Link to={this.props.myroute} onClick={this.hello}>Here</Link>

Update: For ES6 and latest if you want to bind some param with click method, you can use this:

    const someValue = 'some';  
....  
    <Link to={this.props.myroute} onClick={() => hello(someValue)}>Here</Link>

I just wanted to add this version because this is such a useful thread and I think this is a very simple implementation. I have used this multiple times in various types if multithreaded application:

 Task.Factory.StartNew(() =>
      {
        DoLongRunningWork();
        Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
              { txt.Text = "Complete"; }));
      });

The certificate verification process will always verify the DNS name of the certificate presented by the server, with the hostname of the server in the URL used by the client.

The following code

HttpPost post = new HttpPost("https://74.125.236.52/accounts/ClientLogin");

will result in the certificate verification process verifying whether the common name of the certificate issued by the server, i.e. www.google.com matches the hostname i.e. 74.125.236.52. Obviously, this is bound to result in failure (you could have verified this by browsing to the URL https://74.125.236.52/accounts/ClientLogin with a browser, and seen the resulting error yourself).

Supposedly, for the sake of security, you are hesitant to write your own TrustManager (and you musn't unless you understand how to write a secure one), you ought to look at establishing DNS records in your datacenter to ensure that all lookups to www.google.com will resolve to 74.125.236.52; this ought to be done either in your local DNS servers or in the hosts file of your OS; you might need to add entries to other domains as well. Needless to say, you will need to ensure that this is consistent with the records returned by your ISP.

If you don't want the image to affect the layout at all (and float on top of other content) you can apply the following CSS to the image:

position:absolute;
right:0;
top:0;

If you want it to float at the right of a particular parent section, you can add position: relative to that section.

$(':focus')[0] will give you the actual element.

$(':focus') will give you an array of elements, usually only one element is focused at a time so this is only better if you somehow have multiple elements focused.

There are many ways to achieve this, like flatten-and-filter or simply enumerate, but I think using Boolean/mask array is the easiest one (and iirc a much faster one):

>>> y = np.array([[123,24123,32432], [234,24,23]])
array([[  123, 24123, 32432],
       [  234,    24,    23]])
>>> b = y > 200
>>> b
array([[False,  True,  True],
       [ True, False, False]], dtype=bool)
>>> y[b]
array([24123, 32432,   234])
>>> len(y[b])
3
>>>> y[b].sum()
56789

Update:

As nneonneo has answered, if all you want is the number of elements that passes threshold, you can simply do:

>>>> (y>200).sum()
3

which is a simpler solution.

Speed comparison with filter:

### use boolean/mask array ###

b = y > 200

%timeit y[b]
100000 loops, best of 3: 3.31 us per loop

%timeit y[y>200]
100000 loops, best of 3: 7.57 us per loop

### use filter ###

x = y.ravel()
%timeit filter(lambda x:x>200, x)
100000 loops, best of 3: 9.33 us per loop

%timeit np.array(filter(lambda x:x>200, x))
10000 loops, best of 3: 21.7 us per loop

%timeit filter(lambda x:x>200, y.ravel())
100000 loops, best of 3: 11.2 us per loop

%timeit np.array(filter(lambda x:x>200, y.ravel()))
10000 loops, best of 3: 22.9 us per loop

*** use numpy.where ***

nb = np.where(y>200)
%timeit y[nb]
100000 loops, best of 3: 2.42 us per loop

%timeit y[np.where(y>200)]
100000 loops, best of 3: 10.3 us per loop

Your Last Edittext .setOnEditorActionListener call this method automatic hit api

I was Call in LoginActivity in et_password

 et_Pass.setOnEditorActionListener(new TextView.OnEditorActionListener() {
            public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                if ((event != null && (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) || (actionId == EditorInfo.IME_ACTION_DONE)) {

                    Log.i(TAG,"Enter pressed");
                    Log.i(Check Internet," and Connect To Server");

                }
                return false;
            }
        });
