I've created a gist testing some different ways of resolving promises, with results. It may be helpful to see the options that work.

From The Swift Programming Language:

The Sort Function Swift’s standard library provides a function called sort, which sorts an array of values of a known type, based on the output of a sorting closure that you provide. Once it completes the sorting process, the sort function returns a new array of the same type and size as the old one, with its elements in the correct sorted order.

The sort function has two declarations.

The default declaration which allows you to specify a comparison closure:

func sort<T>(array: T[], pred: (T, T) -> Bool) -> T[]

And a second declaration that only take a single parameter (the array) and is "hardcoded to use the less-than comparator."

func sort<T : Comparable>(array: T[]) -> T[]

Example:
sort( _arrayToSort_ ) { $0 > $1 }

I tested a modified version of your code in a playground with the closure added on so I could monitor the function a little more closely, and I found that with n set to 1000, the closure was being called about 11,000 times.

let n = 1000
let x = Int[](count: n, repeatedValue: 0)
for i in 0..n {
    x[i] = random()
}
let y = sort(x) { $0 > $1 }

It is not an efficient function, an I would recommend using a better sorting function implementation.

EDIT:

I took a look at the Quicksort wikipedia page and wrote a Swift implementation for it. Here is the full program I used (in a playground)

import Foundation

func quickSort(inout array: Int[], begin: Int, end: Int) {
    if (begin < end) {
        let p = partition(&array, begin, end)
        quickSort(&array, begin, p - 1)
        quickSort(&array, p + 1, end)
    }
}

func partition(inout array: Int[], left: Int, right: Int) -> Int {
    let numElements = right - left + 1
    let pivotIndex = left + numElements / 2
    let pivotValue = array[pivotIndex]
    swap(&array[pivotIndex], &array[right])
    var storeIndex = left
    for i in left..right {
        let a = 1 // <- Used to see how many comparisons are made
        if array[i] <= pivotValue {
            swap(&array[i], &array[storeIndex])
            storeIndex++
        }
    }
    swap(&array[storeIndex], &array[right]) // Move pivot to its final place
    return storeIndex
}

let n = 1000
var x = Int[](count: n, repeatedValue: 0)
for i in 0..n {
    x[i] = Int(arc4random())
}

quickSort(&x, 0, x.count - 1) // <- Does the sorting

for i in 0..n {
    x[i] // <- Used by the playground to display the results
}

Using this with n=1000, I found that

1. quickSort() got called about 650 times,
2. about 6000 swaps were made,
3. and there are about 10,000 comparisons

It seems that the built-in sort method is (or is close to) quick sort, and is really slow...

Have you tried using rclone.org?

With rclone you could do something like

rclone copy "${source}/${subfolder}/" "${target}/${subfolder}/" --progress --multi-thread-streams=N

where --multi-thread-streams=N represents the number of threads you wish to spawn.

Suspended. The session is waiting for an event, such as I/O, to complete.

In my case, the database was related to an old Sharepoint install. Stopping and disabling related services in the server manager "unhung" the take offline action, which had been running for 40 minutes, and it completed immediately.

You may wish to check if any services are currently utilizing the database.

You can write bash in your package.json:

# package.json
{
  "name": ...,
  "version": ...,
  "scripts": {
    "build": "NODE_ENV=production npm run webpack && cp -v <this> <that> && echo ok",
    ...
  }
}

Just use good old HTML:

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

Wrap it as the subject of a link, if you so desire:

<a href="http://somewhere.com"><input type="button" value="Submit" /></a>

Or if you decide you want javascript to provide some other functionality:

<input type="button" value="Cancel" onclick="javascript: someFunctionThatCouldIncludeRedirect();"/>

In bootstrap 4 it is much easier to have a border on the fieldset that blends with the legend. You don't need custom css to achieve it, it can be done like this:

<fieldset class="border p-2">
   <legend  class="w-auto">Your Legend</legend>
</fieldset>

which looks like this:

None of the answers here worked for me out of the box, here is what worked for me:

Create pipes/keys.ts with contents:

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({name: 'keys'})
export class KeysPipe implements PipeTransform
{
    transform(value:any, args:string[]): any {
        let keys:any[] = [];
        for (let key in value) {
            keys.push({key: key, value: value[key]});
        }
        return keys;
    }
}

Add to app.module.ts (Your main module):

import { KeysPipe } from './pipes/keys';

and then add to your module declarations array something like this:

@NgModule({
    declarations: [
        KeysPipe
    ]
})
export class AppModule {}

Then in your view template you can use something like this:

<option *ngFor="let entry of (myData | keys)" value="{{ entry.key }}">{{ entry.value }}</option>

Here is a good reference I found if you want to read more.

They're just trawling lists of web sites, and recording the resulting IP addresses in a database.

All you're seeing is the reverse mapping of that list. It's not guaranteed to be a full list (indeed more often than not it won't be) because it's impossible to learn every possible web site address.

Bower has finally been deprecated. End of story.

Older answer

From Mattias Petter Johansson, JavaScript developer at Spotify:

In almost all cases, it's more appropriate to use Browserify and npm over Bower. It is simply a better packaging solution for front-end apps than Bower is. At Spotify, we use npm to package entire web modules (html, css, js) and it works very well.

Bower brands itself as the package manager for the web. It would be awesome if this was true - a package manager that made my life better as a front-end developer would be awesome. The problem is that Bower offers no specialized tooling for the purpose. It offers NO tooling that I know of that npm doesn't, and especially none that is specifically useful for front-end developers. There is simply no benefit for a front-end developer to use Bower over npm.

We should stop using bower and consolidate around npm. Thankfully, that is what is happening:

With browserify or webpack, it becomes super-easy to concatenate all your modules into big minified files, which is awesome for performance, especially for mobile devices. Not so with Bower, which will require significantly more labor to get the same effect.

npm also offers you the ability to use multiple versions of modules simultaneously. If you have not done much application development, this might initially strike you as a bad thing, but once you've gone through a few bouts of Dependency hell you will realize that having the ability to have multiple versions of one module is a pretty darn great feature. Note that npm includes a very handy dedupe tool that automatically makes sure that you only use two versions of a module if you actually have to - if two modules both can use the same version of one module, they will. But if they can't, you have a very handy out.

(Note that Webpack and rollup are widely regarded to be better than Browserify as of Aug 2016.)

There is a simple solution, which is the HTML5 input event. It's supported in current versions of all major browsers for <input type="text"> elements and there's a simple workaround for IE < 9. See the following answers for more details:

• jQuery keyboard events
• Catch only keypresses that change input?

Example (except IE < 9: see links above for workaround):

$("#your_id").on("input", function() {
    alert("Change to " + this.value);
});

How will the browser know when to run the code inside script tag? So, to make the code run after the window is loaded completely,

window.onload = doStuff;

function doStuff() {
    var e = document.getElementById("db_info");
    e.innerHTML='Found you';
}

The other alternative is to keep your <script...</script> just before the closing </body> tag.

Inspired by Robert K's solution, strips html tags and prevents executing scripts and eventhandlers like: <img src=fake onerror="prompt(1)"> Tested on latest Chrome, FF, IE (should work from IE9, but haven't tested).

var decodeEntities = (function () {
        //create a new html document (doesn't execute script tags in child elements)
        var doc = document.implementation.createHTMLDocument("");
        var element = doc.createElement('div');

        function getText(str) {
            element.innerHTML = str;
            str = element.textContent;
            element.textContent = '';
            return str;
        }

        function decodeHTMLEntities(str) {
            if (str && typeof str === 'string') {
                var x = getText(str);
                while (str !== x) {
                    str = x;
                    x = getText(x);
                }
                return x;
            }
        }
        return decodeHTMLEntities;
    })();

Simply call:

decodeEntities('<img src=fake onerror="prompt(1)">');
decodeEntities("<script>alert('aaa!')</script>");

I've noticed that if you set the theme in the AndroidManifest, it seems to get rid of that short time where you can see the action bar. So, try adding this to your manifest:

<android:theme="@android:style/Theme.NoTitleBar">

Just add it to your application tag to apply it app-wide.

Try this:

if (!emailRegistration.matches("[a-zA-Z0-9._-]+@[a-z]+\.[a-z]+")) {
 editTextEmail.setError("Invalid Email Address");
}

Using https://github.com/FluentDateTime/FluentDateTime

DateTime dateTime = DateTime.Now;
DateTime combined = dateTime + 36.Hours();
Console.WriteLine(combined);

If you're using Rails 3.2 or Rails 4 you should use request.original_url to get the current URL.

Documentation for the method is at http://api.rubyonrails.org/classes/ActionDispatch/Request.html#method-i-original_url but if you're curious the implementation is:

def original_url
  base_url + original_fullpath
end

how does rails know that user_id is a foreign key referencing user?

Rails itself does not know that user_id is a foreign key referencing user. In the first command rails generate model Micropost user_id:integer it only adds a column user_id however rails does not know the use of the col. You need to manually put the line in the Micropost model

class Micropost < ActiveRecord::Base
  belongs_to :user
end

class User < ActiveRecord::Base
  has_many :microposts
end

the keywords belongs_to and has_many determine the relationship between these models and declare user_id as a foreign key to User model.

The later command rails generate model Micropost user:references adds the line belongs_to :user in the Micropost model and hereby declares as a foreign key.

FYI
Declaring the foreign keys using the former method only lets the Rails know about the relationship the models/tables have. The database is unknown about the relationship. Therefore when you generate the EER Diagrams using software like MySql Workbench you find that there is no relationship threads drawn between the models. Like in the following pic

However, if you use the later method you find that you migration file looks like:

def change
    create_table :microposts do |t|
      t.references :user, index: true

      t.timestamps null: false
    end
    add_foreign_key :microposts, :users

Now the foreign key is set at the database level. and you can generate proper EER diagrams.

Hope this will help someone... Here's a little PHP script I wrote in case you need to copy some columns but not others, and/or the columns are not in the same order on both tables. As long as the columns are named the same, this will work. So if table A has [userid, handle, something] and tableB has [userID, handle, timestamp], then you'd "SELECT userID, handle, NOW() as timestamp FROM tableA", then get the result of that, and pass the result as the first parameter to this function ($z). $toTable is a string name for the table you're copying to, and $link_identifier is the db you're copying to. This is relatively fast for small sets of data. Not suggested that you try to move more than a few thousand rows at a time this way in a production setting. I use this primarily to back up data collected during a session when a user logs out, and then immediately clear the data from the live db to keep it slim.

 function mysql_multirow_copy($z,$toTable,$link_identifier) {
            $fields = "";
            for ($i=0;$i<mysql_num_fields($z);$i++) {
                if ($i>0) {
                    $fields .= ",";
                }
                $fields .= mysql_field_name($z,$i);
            }
            $q = "INSERT INTO $toTable ($fields) VALUES";
            $c = 0;
            mysql_data_seek($z,0); //critical reset in case $z has been parsed beforehand. !
            while ($a = mysql_fetch_assoc($z)) {
                foreach ($a as $key=>$as) {
                    $a[$key] = addslashes($as);
                    next ($a);
                }
                if ($c>0) {
                    $q .= ",";
                }
                $q .= "('".implode(array_values($a),"','")."')";
                $c++;
            }
            $q .= ";";
            $z = mysql_query($q,$link_identifier);
            return ($q);
        }

To expand on what has been provided for automatically exporting data as csv to a network share via SQL Server Agent.

(1) Enable the xp_cmdshell procedure:

-- To allow advanced options to be changed.
EXEC sp_configure 'show advanced options', 1
RECONFIGURE
GO

-- Enable the xp_cmdshell procedure
EXEC sp_configure 'xp_cmdshell', 1
RECONFIGURE
GO

(2) Create a login 'Domain\TestUser' (windows user) for the non-sysadmin user that has public access to the master database. Done through user mapping

(3) Give log on as batch job: Navigate to Local Security Policy -> Local Policies -> User Rights Assignment. Add user to "Log on as a batch job"

(4) Give read/write permissions to network folder for domain\user

(5) Grant EXEC permission on the xp_cmdshell stored procedure:

GRANT EXECUTE ON xp_cmdshell TO [Domain\TestUser]

(6) Create a proxy account that xp_cmdshell will be run under using sp_xp_cmdshell_proxy_account

EXEC sp_xp_cmdshell_proxy_account 'Domain\TestUser', 'password_for_domain_user'

(7) If the sp_xp_cmdshell_proxy_account command doesn't work, manually create it

create credential ##xp_cmdshell_proxy_account## with identity = 'Domain\DomainUser', secret = 'password'

(8) Enable SQL Server Agent. Open SQL Server Configuration Manager, navigate to SQL Server Services, enable SQL Server Agent.

(9) Create automated job. Open SSMS, select SQL Server Agent, then right-click jobs and click "New Job".

(10) Select "Owner" as your created user. Select "Steps", make "type" = T-SQL. Fill out command field similar to below. Set delimiter as ','

EXEC master..xp_cmdshell 'SQLCMD -q "select * from master" -o file.csv -s "," 

(11) Fill out schedules accordingly.

You may use fnDrawCallback or fnInfoCallback to detect changes, when next is clicked both of them are fired.

But beware, page changes are not the only source that can fire those callbacks.

Here is the simple logic to find Biggest/Largest Number

Input : 11, 33, 1111, 4, 0 Output : 1111

namespace PurushLogics
{
    class Purush_BiggestNumber
    {
        static void Main()
        {
            int count = 0;
            Console.WriteLine("Enter Total Number of Integers\n");
            count = int.Parse(Console.ReadLine());

            int[] numbers = new int[count];

            Console.WriteLine("Enter the numbers"); // Input 44, 55, 111, 2 Output = "111"
            for (int temp = 0; temp < count; temp++)
            {
                numbers[temp] = int.Parse(Console.ReadLine());
            }

            int largest = numbers[0];
            for (int big = 1; big < numbers.Length; big++)
            {
                if (largest < numbers[big])
                {
                    largest = numbers[big];
                }
            }
            Console.WriteLine(largest);
            Console.ReadKey();
        }
    }
}

Answer 1 - "response" gave a nice answer/link for it. To put it in short, "auto" is the default, so it is like removing any changes in the width of an element

Answer 2 - use width: 100% instead. It will fill the 100% of the parent container, in this case, the "form".

For Jackson versions < 2.0 use this annotation on the class being serialized:

@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)

Standard C doesn't define binary constants. There's a GNU (I believe) extension though (among popular compilers, clang adapts it as well): the 0b prefix:

int foo = 0b1010;

If you want to stick with standard C, then there's an option: you can combine a macro and a function to create an almost readable "binary constant" feature:

#define B(x) S_to_binary_(#x)

static inline unsigned long long S_to_binary_(const char *s)
{
        unsigned long long i = 0;
        while (*s) {
                i <<= 1;
                i += *s++ - '0';
        }
        return i;
}

And then you can use it like this:

int foo = B(1010);

If you turn on heavy compiler optimizations, the compiler will most likely eliminate the function call completely (constant folding) or will at least inline it, so this won't even be a performance issue.

Proof:

The following code:

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


#define B(x) S_to_binary_(#x)

static inline unsigned long long S_to_binary_(const char *s)
{
    unsigned long long i = 0;
    while (*s) {
        i <<= 1;
        i += *s++ - '0';
    }
    return i;
}

int main()
{
    int foo = B(001100101);

    printf("%d\n", foo);

    return 0;
}

has been compiled using clang -o baz.S baz.c -Wall -O3 -S, and it produced the following assembly:

    .section    __TEXT,__text,regular,pure_instructions
    .globl  _main
    .align  4, 0x90

So clang completely eliminated the call to the function, and replaced its return value with 101. Neat, huh?

In Java, Dates are internally represented in UTC milliseconds since the epoch (so timezones are not taken into account, that's why you get the same results, as getTime() gives you the mentioned milliseconds).
In your solution:

Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
long gmtTime = cSchedStartCal.getTime().getTime();

long timezoneAlteredTime = gmtTime + TimeZone.getTimeZone("Asia/Calcutta").getRawOffset();
Calendar cSchedStartCal1 = Calendar.getInstance(TimeZone.getTimeZone("Asia/Calcutta"));
cSchedStartCal1.setTimeInMillis(timezoneAlteredTime);

you just add the offset from GMT to the specified timezone ("Asia/Calcutta" in your example) in milliseconds, so this should work fine.

Another possible solution would be to utilise the static fields of the Calendar class:

//instantiates a calendar using the current time in the specified timezone
Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
//change the timezone
cSchedStartCal.setTimeZone(TimeZone.getTimeZone("Asia/Calcutta"));
//get the current hour of the day in the new timezone
cSchedStartCal.get(Calendar.HOUR_OF_DAY);

Refer to stackoverflow.com/questions/7695859/ for a more in-depth explanation.

Remove the visible="false" attribute and add a CSS class that is not visible by default. Then you should be able to reference the dropdown by the correct id, for example:

$("#ctl00_cphTest_test1").show();

Above ID you should serach for in the source of the rendered page in your browser.

There is also change that Eclipse Project is somehow corrupted. Usually case like this Eclipse is added some duplicated .jars in your project and those .jars are usually same as Maven Dependency .jars.

If your project look like below example there is huge change that Maven Dependencies are duplicated and should be removed manually.

e.g. (Project Explorer View)
src/main/java
src/test/java
spring-boot-vaadin.jar
spring-aop.jar
Maven Dependencies
  spring-boot-vaadin.jar
  spring-aop.jar
etc...

...and this is cure :-)

Just remove all REPO_M2/... paths and update project.

On a side note. If you are using @media queries (such as @media screen (max-width:500px)) pay particular attention to applying @media query AFTER you are done with normal styles. Because @media query will be crossed out (even though it is more specific) if followed by css that manipulates the same elements. Example:

@media (max-width:750px){
#buy-box {width: 300px;}
}

#buy-box{
width:500px;
}

** width will be 500px and 300px will be crossed out in Developer Tools. **

#buy-box{
width:500px;
}

@media (max-width:750px){
#buy-box {width: 300px;}
}

** width will be 300px and 500px will be crossed out **

Based upon your comments - your path statement has been changed/is incorrect or the path variable is being incorrectly used for another purpose.

Check if you have any elevation on one of the Views in XML. If so, add elevation to the other item or remove the elevation to solve the issue. From there, it's the order of the views that dictates what comes above the other.

In Spark < 1.6 If you create a HiveContext, not the plain old SqlContext you can use the HiveQL DISTRIBUTE BY colX... (ensures each of N reducers gets non-overlapping ranges of x) & CLUSTER BY colX... (shortcut for Distribute By and Sort By) for example;

df.registerTempTable("partitionMe")
hiveCtx.sql("select * from partitionMe DISTRIBUTE BY accountId SORT BY accountId, date")

Not sure how this fits in with Spark DF api. These keywords aren't supported in the normal SqlContext (note you dont need to have a hive meta store to use the HiveContext)

EDIT: Spark 1.6+ now has this in the native DataFrame API

Synchronized on the method declaration is syntactical sugar for this:

 public void addA() {
     synchronized (this) {
          a++;
     }
  }

On a static method it is syntactical sugar for this:

 ClassA {
     public static void addA() {
          synchronized(ClassA.class) {
              a++;
          }
 }

I think if the Java designers knew then what is understood now about synchronization, they would not have added the syntactical sugar, as it more often than not leads to bad implementations of concurrency.

Data structure alignment is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding. When a modern computer reads from or writes to a memory address, it will do this in word sized chunks (e.g. 4 byte chunks on a 32-bit system) or larger. Data alignment means putting the data at a memory address equal to some multiple of the word size, which increases the system’s performance due to the way the CPU handles memory. To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

1. In order to align the data in memory, one or more empty bytes (addresses) are inserted (or left empty) between memory addresses which are allocated for other structure members while memory allocation. This concept is called structure padding.
2. Architecture of a computer processor is such a way that it can read 1 word (4 byte in 32 bit processor) from memory at a time.
3. To make use of this advantage of processor, data are always aligned as 4 bytes package which leads to insert empty addresses between other member’s address.
4. Because of this structure padding concept in C, size of the structure is always not same as what we think.

Use Python 2.7, is has more 3rd party libs at the moment. (Edit: see below).

I recommend you using the stdlib module urllib2, it will allow you to comfortably get web resources. Example:

import urllib2

response = urllib2.urlopen("http://google.de")
page_source = response.read()

For parsing the code, have a look at BeautifulSoup.

BTW: what exactly do you want to do:

Just for background, I need to download a page and replace any img with ones I have

Edit: It's 2014 now, most of the important libraries have been ported, and you should definitely use Python 3 if you can. python-requests is a very nice high-level library which is easier to use than urllib2.

What solved the issue on my case was go to:

cd C:\Program Files\Python37\Scripts

And run below command:

easy_install.exe pip

The requirements of the original question clearly couldn't benefit from string interpolation, as it seems like it's a runtime processing of arbitrary replacement keys.

However, if you just had to do string interpolation, you can use:

const str = `My name is ${replacements.name} and my age is ${replacements.age}.`

Note the backticks delimiting the string, they are required.

For an answer suiting the particular OP's requirement, you could use String.prototype.replace() for the replacements.

The following code will handle all matches and not touch ones without a replacement (so long as your replacement values are all strings, if not, see below).

var replacements = {"%NAME%":"Mike","%AGE%":"26","%EVENT%":"20"},
    str = 'My Name is %NAME% and my age is %AGE%.';

str = str.replace(/%\w+%/g, function(all) {
   return replacements[all] || all;
});

jsFiddle.

If some of your replacements are not strings, be sure they exists in the object first. If you have a format like the example, i.e. wrapped in percentage signs, you can use the in operator to achieve this.

jsFiddle.

However, if your format doesn't have a special format, i.e. any string, and your replacements object doesn't have a null prototype, use Object.prototype.hasOwnProperty(), unless you can guarantee that none of your potential replaced substrings will clash with property names on the prototype.

jsFiddle.

Otherwise, if your replacement string was 'hasOwnProperty', you would get a resultant messed up string.

jsFiddle.

As a side note, you should be called replacements an Object, not an Array.

I had a situation of git status showing changes, but git diff printing nothing, although there were changes in several lines. However:

$ git diff data.txt > myfile
$ cat myfile
<prints diff>

Git 2.20.1 on raspbian. Other commands like git checkout, git pull are printing to stdout without problems.

EDIT:

As others have indicated, the suggestion of using strings may lead to issues.

You should be using iostream without the .h.

Early implementations used the .h variants but the standard mandates the more modern style.

Run this:

init = tf.global_variables_initializer()
sess.run(init)

Or (depending on the version of TF that you have):

init = tf.initialize_all_variables()
sess.run(init)

Had the same problem. The solution is to add a \ at the end of %ANT_HOME%\bin so it became %ANT_HOME%\bin\

Worked for me. (Should be system var)

def stringToNumbers(ord(message)):
    return stringToNumbers
    stringToNumbers.append = (ord[0])
    stringToNumbers = ("morocco")

I found the solution to this. There is a temporary tablespace called TEMP which is used internally by database for operations like distinct, joins,etc. Since my query(which has 4 joins) fetches almost 50 million records the TEMP tablespace does not have that much space to occupy all data. Hence the query fails even though my tablespace has free space.So, after increasing the size of TEMP tablespace the issue was resolved. Hope this helps someone with the same issue. Thanks :)

Note that you can use the Polynomial class directly to do the fitting and return a Polynomial instance.

from numpy.polynomial import Polynomial

p = Polynomial.fit(x, y, 4)
plt.plot(*p.linspace())

p uses scaled and shifted x values for numerical stability. If you need the usual form of the coefficients, you will need to follow with

pnormal = p.convert(domain=(-1, 1))

1. open the folder where your python is installed
2. open scripts folder
3. type cmd in the address bar. It opens a command prompt window in that location
4. type pip install pygame and press enter
5. it should download and install pygame module
6. now run your code. It works fine :-)

You should use npm run-script build or npm build <project_folder>. More info here: https://docs.npmjs.com/cli/build.

Had the same issue, but my code must work on both PHP 5 & PHP 7..

Here is my piece of code, which solved this.. Input a date in dmY format with one of delimiters "/ . -"

<?php
function DateToEN($date){
  if ($date!=""){
    list($d, $m, $y) = function_exists("split") ?  split("[/.-]", $date) : preg_split("/[\/\.\-]+/", $date);
    return $y."-".$m."-".$d;
  }else{
    return false;
  }
}
?>

Suppose you have data in A1:A10 and B1:B10 and you want to highlight which values in A1:A10 do not appear in B1:B10.

Try as follows:

1. Format > Conditional Formating...
2. Select 'Formula Is' from drop down menu

3. Enter the following formula:

   =ISERROR(MATCH(A1,$B$1:$B$10,0))

4. Now select the format you want to highlight the values in col A that do not appear in col B

This will highlight any value in Col A that does not appear in Col B.

return StatusCode((int)HttpStatusCode.InternalServerError, e);

Should be used in non-ASP.NET contexts (see other answers for ASP.NET Core).

HttpStatusCode is an enumeration in System.Net.

The reason why Pycharm make it as a warning because Python will pass self as the first argument when calling a none static method (not add @staticmethod). Pycharm knows it.

Example:

class T:
    def test():
        print "i am a normal method!"

t = T()
t.test()
output:
Traceback (most recent call last):
  File "F:/Workspace/test_script/test.py", line 28, in <module>
    T().test()
TypeError: test() takes no arguments (1 given)

I'm from Java, in Java "self" is called "this", you don't need write self(or this) as argument in class method. You can just call self as you need inside the method. But Python "has to" pass self as a method argument.

By understanding this you don't need any Workaround as @BobStein answer.

You should be able to declare a cursor to be a bind variable (called parameters in other DBMS')

like Vincent wrote, you can do something like this:

begin
  open :yourCursor
    for 'SELECT "'|| :someField ||'" from yourTable where x = :y'
      using :someFilterValue;
end;

You'd have to bind 3 vars to that script. An input string for "someField", a value for "someFilterValue" and an cursor for "yourCursor" which has to be declared as output var.

Unfortunately, I have no idea how you'd do that from C++. (One could say fortunately for me, though. ;-) )

Depending on which access library you use, it might be a royal pain or straight forward.

Set sound to notification channel

        Uri alarmUri = Uri.fromFile(new File(<path>));

        AudioAttributes attributes = new AudioAttributes.Builder()
                .setUsage(AudioAttributes.USAGE_ALARM)
                .build();

        channel.setSound(alarmUri, attributes);

I modifie this list and add a List to the samples try this

Pseudocode

Sample {
   List<String> values;
   List<String> getList() {
   return values}
}



for(Sample s : list) {
   if(s.getString.getList.contains("three") {
      return s;
   }
}

Another solution could be to use Number object parser like this:

let result = Number(new Date("2012-02-10T13:19:11+0000"));_x000D_
let resultWithGetTime = (new Date("2012-02-10T13:19:11+0000")).getTime();_x000D_
console.log(result);_x000D_
console.log(resultWithGetTime);

This converts to milliseconds just like getTime() on Date object

I see this has been answered, but it seems like you could avoid all of this 'remapping' of the enter key by simply hooking your validation into the AcceptButton on a form. ie. you have 3 textboxes (txtA,txtB,txtC) and an 'OK' button set to be AcceptButton (and TabOrder set properly). So, if in txtA and you hit enter, if the data is invalid, your focus will stay in txtA, but if it is valid, assuming the other txts need input, validation will just put you into the next txt that needs valid input thus simulating TAB behaviour... once all txts have valid input, pressing enter will fire a succsessful validation and close form (or whatever...) Make sense?

In windows, if you need the a ${PWD} env variable in your docker-compose.yml you can creat a .env file in the same directory as your docker-compose.yml file then insert manualy the location of your folder.

CMD (pwd_var.bat) :

echo PWD=%cd% >> .env

Powershell (pwd_var.ps1) :

$PSDefaultParameterValues['Out-File:Encoding'] = 'utf8'; echo "PWD=$(get-location).path" >> .env

There is more good features hear for docker-compose .env variables: https://docs.docker.com/compose/reference/envvars/ especially for the COMPOSE_CONVERT_WINDOWS_PATHS env variable that allow docker compose to accept windows path with baskslash "\".

When you want to share a file on windows, the file must exist before sharing it with the container.

this will unhide all files and folders on your computer

attrib -r -s -h /S /D

It can also be used as below:

from datetime import datetime
start_date = datetime(2016,3,1)
end_date = datetime(2016,3,10)

Maybe you'd like to check if the previous point of history is within your app. For example, if you enter directly to your app and do location.back() (by pressing a <- back button in a toolbar for example), you'd be back to your browser's main page, instead of going somewhere else within your app.

This is how I check for this:

import { Component } from '@angular/core';
import { ActivatedRoute, Router } from '@angular/router';
import { Location } from '@angular/common';

@Component({
  selector: 'app-foo',
  template: ''
})
export class FooComponent {

  private readonly canGoBack: boolean;

  constructor(
    private readonly route: ActivatedRoute,
    private readonly router: Router,
    private readonly location: Location
  ) {
    // This is where the check is done. Make sure to do this
    // here in the constructor, otherwise `getCurrentNavigation()`
    // will return null. 
    this.canGoBack = !!(this.router.getCurrentNavigation()?.previousNavigation);
  }

  goBack(): void {
    if (this.canGoBack) {
      // We can safely go back to the previous location as
      // we know it's within our app.
      this.location.back();
    } else {
      // There's no previous navigation.
      // Here we decide where to go. For example, let's say the
      // upper level is the index page, so we go up one level.
      this.router.navigate(['..'], {relativeTo: this.route});
    }
  }

}

We check if the navigation that loaded the current route has a previous sibling. This has to be done in the constructor, while the navigation process is still active.

This doesn't come without caveats though:

• canGoBack will be false even if the previous location is actually within our app but the page was refreshed.
• The user might want to "go back" to the previous page (where the goBack() ocurred) by clicking the browser's back button, but since the app went back on history instead of pushing a new location, the user will be going back even further and might get confused.

This is the natural javascript option

var myArray = ['1','2',3,4]_x000D_
_x000D_
myArray.forEach(function(value){_x000D_
  console.log(value);_x000D_
});

However it won't work if you're using await inside the forEach loop because forEach is not asynchronous. you'll be forced to use the second answer or some other equivalent:

let myArray = ["a","b","c","d"];_x000D_
for (let item of myArray) {_x000D_
  console.log(item);_x000D_
}

Or you could create an asyncForEach explained here:

https://codeburst.io/javascript-async-await-with-foreach-b6ba62bbf404

Likely, your problem is that you parsed it okay, and now you're trying to print the contents of the XML and you can't because theres some foreign Unicode characters. Try to encode your unicode string as ascii first:

unicodeData.encode('ascii', 'ignore')

the 'ignore' part will tell it to just skip those characters. From the python docs:

>>> # Python 2: u = unichr(40960) + u'abcd' + unichr(1972)
>>> u = chr(40960) + u'abcd' + chr(1972)
>>> u.encode('utf-8')
'\xea\x80\x80abcd\xde\xb4'
>>> u.encode('ascii')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
UnicodeEncodeError: 'ascii' codec can't encode character '\ua000' in position 0: ordinal not in range(128)
>>> u.encode('ascii', 'ignore')
'abcd'
>>> u.encode('ascii', 'replace')
'?abcd?'
>>> u.encode('ascii', 'xmlcharrefreplace')
'&#40960;abcd&#1972;'

You might want to read this article: http://www.joelonsoftware.com/articles/Unicode.html, which I found very useful as a basic tutorial on what's going on. After the read, you'll stop feeling like you're just guessing what commands to use (or at least that happened to me).

If I had to guess, I'd say you installed the PPA 7.1.8 as CLI only (php7-cli). You're getting your version info from that, but your libapache2-mod-php package is still 14.04 main which is 5.6. Check your phpinfo in your browser to confirm the version. You might also consider migrating to Ubuntu 16.04 to get PHP 7.0 in main.

Command to put list of all files and folders into a text file is as below:

Eg: dir /b /s | sort > ListOfFilesFolders.txt

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

You cannot.

JavaScript cannot access files on the local computer for security reasons, even to check their size.

The only thing you can do is use JavaScript to submit the form with the file field to a server-side script, which can then measure its size and return it.

According to http://tools.android.com/tech-docs/new-build-system/migrating-from-eclipse-projects, You have a couple of choices
- simply importing
- pre-exporting first from Eclipse.

Pre-exporting from eclipse may be the better choice if your project contains a lot of relationships that are Eclipse-specific. A.S. cannot 'translate' everything Eclipse can produce. If you want to continue using Eclipse as well as A.S. on this project code, this is the better choice. If you choose this method, please read the above link, there are some important pre-requisites.

Simply importing into AS will let AS 'translate' and rearrange the project, and is the recommended method, especially if you have no intention of returning to Eclipse. In this case, you let the A.S. wizard do everything and you dont need to manually generate gradle files.

This post is old enough that this answer will probably be little use to the OP, but I spent forever trying to answer this same question, so I thought I would update it with my findings.

This answer assumes that you already have a working SQL query in place in your Excel document. There are plenty of tutorials to show you how to accomplish this on the web, and plenty that explain how to add a parameterized query to one, except that none seem to work for an existing, OLE DB query.

So, if you, like me, got handed a legacy Excel document with a working query, but the user wants to be able to filter the results based on one of the database fields, and if you, like me, are neither an Excel nor a SQL guru, this might be able to help you out.

Most web responses to this question seem to say that you should add a “?” in your query to get Excel to prompt you for a custom parameter, or place the prompt or the cell reference in [brackets] where the parameter should be. This may work for an ODBC query, but it does not seem to work for an OLE DB, returning “No value given for one or more required parameters” in the former instance, and “Invalid column name ‘xxxx’” or “Unknown object ‘xxxx’” in the latter two. Similarly, using the mythical “Parameters…” or “Edit Query…” buttons is also not an option as they seem to be permanently greyed out in this instance. (For reference, I am using Excel 2010, but with an Excel 97-2003 Workbook (*.xls))

What we can do, however, is add a parameter cell and a button with a simple routine to programmatically update our query text.

First, add a row above your external data table (or wherever) where you can put a parameter prompt next to an empty cell and a button (Developer->Insert->Button (Form Control) – You may need to enable the Developer tab, but you can find out how to do that elsewhere), like so:

Next, select a cell in the External Data (blue) area, then open Data->Refresh All (dropdown)->Connection Properties… to look at your query. The code in the next section assumes that you already have a parameter in your query (Connection Properties->Definition->Command Text) in the form “WHERE (DB_TABLE_NAME.Field_Name = ‘Default Query Parameter')” (including the parentheses). Clearly “DB_TABLE_NAME.Field_Name” and “Default Query Parameter” will need to be different in your code, based on the database table name, database value field (column) name, and some default value to search for when the document is opened (if you have auto-refresh set). Make note of the “DB_TABLE_NAME.Field_Name” value as you will need it in the next section, along with the “Connection name” of your query, which can be found at the top of the dialog.

Close the Connection Properties, and hit Alt+F11 to open the VBA editor. If you are not on it already, right click on the name of the sheet containing your button in the “Project” window, and select “View Code”. Paste the following code into the code window (copying is recommended, as the single/double quotes are dicey and necessary).

Sub RefreshQuery()
 Dim queryPreText As String
 Dim queryPostText As String
 Dim valueToFilter As String
 Dim paramPosition As Integer
 valueToFilter = "DB_TABLE_NAME.Field_Name ="

 With ActiveWorkbook.Connections("Connection name").OLEDBConnection
     queryPreText = .CommandText
     paramPosition = InStr(queryPreText, valueToFilter) + Len(valueToFilter) - 1
     queryPreText = Left(queryPreText, paramPosition)
     queryPostText = .CommandText
     queryPostText = Right(queryPostText, Len(queryPostText) - paramPosition)
     queryPostText = Right(queryPostText, Len(queryPostText) - InStr(queryPostText, ")") + 1)
     .CommandText = queryPreText & " '" & Range("Cell reference").Value & "'" & queryPostText
 End With
 ActiveWorkbook.Connections("Connection name").Refresh
End Sub

Replace “DB_TABLE_NAME.Field_Name” and "Connection name" (in two locations) with your values (the double quotes and the space and equals sign need to be included).

Replace "Cell reference" with the cell where your parameter will go (the empty cell from the beginning) - mine was the second cell in the first row, so I put “B1” (again, the double quotes are necessary).

Save and close the VBA editor.

Enter your parameter in the appropriate cell.

Right click your button to assign the RefreshQuery sub as the macro, then click your button. The query should update and display the right data!

Notes: Using the entire filter parameter name ("DB_TABLE_NAME.Field_Name =") is only necessary if you have joins or other occurrences of equals signs in your query, otherwise just an equals sign would be sufficient, and the Len() calculation would be superfluous. If your parameter is contained in a field that is also being used to join tables, you will need to change the "paramPosition = InStr(queryPreText, valueToFilter) + Len(valueToFilter) - 1" line in the code to "paramPosition = InStr(Right(.CommandText, Len(.CommandText) - InStrRev(.CommandText, "WHERE")), valueToFilter) + Len(valueToFilter) - 1 + InStr(.CommandText, "WHERE")" so that it only looks for the valueToFilter after the "WHERE".

This answer was created with the aid of datapig’s “BaconBits” where I found the base code for the query update.

You can use the slice method:

a = "foobar"
a.slice! "foo"
=> "foo"
a
=> "bar"

there is a non '!' version as well. More info can be seen in the documentation about other versions as well: http://www.ruby-doc.org/core/classes/String.html#method-i-slice-21

You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document

You can do this really easily with the jQuery-Columns Plugin for example to split a ul with a class of .mylist you would do

$('.mylist').cols(2);

Here's a live example on jsfiddle

I like this better than with CSS because with the CSS solution not everything aligns vertically to the top.

Add comma separated folder paths sonar.exclusions=**/abc/**,**/def/**

This worked in an angular project

You can try this:

<style name="MyCustomTabLayout" parent="Widget.Design.TabLayout">
    <item name="tabBackground">@drawable/background</item>
</style>

In your background xml file:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_selected="true" android:drawable="@color/white" />
    <item android:drawable="@color/black" />
</selector>

You can apply a style to your activity by doing:

super.setTheme( R.style.MyAppTheme );

or Android default:

super.setTheme( android.R.style.Theme );

in your activity, before setContentView().

Spark2 is based on Spark which is now no longer maintained. Cluster is its successor, and it has some cool features, like spawning one worker process per CPU core and respawning dead workers.

The exit() and quit() built in functions do just what you want. No import of sys needed.

Alternatively, you can raise SystemExit, but you need to be careful not to catch it anywhere (which shouldn't happen as long as you specify the type of exception in all your try.. blocks).

Calling destructor via a pointer to a base class

struct Base {
  virtual void f() {}
  virtual ~Base() {}
};

struct Derived : Base {
  void f() override {}
  ~Derived() override {}
};

Base* base = new Derived;
base->f(); // calls Derived::f
base->~Base(); // calls Derived::~Derived

Virtual destructor call is no different from any other virtual function call.

For base->f(), the call will be dispatched to Derived::f(), and it's the same for base->~Base() - its overriding function - the Derived::~Derived() will be called.

Same happens when destructor is being called indirectly, e.g. delete base;. The delete statement will call base->~Base() which will be dispatched to Derived::~Derived().

Abstract class with non-virtual destructor

If you are not going to delete object through a pointer to its base class - then there is no need to have a virtual destructor. Just make it protected so that it won't be called accidentally:

// library.hpp

struct Base {
  virtual void f() = 0;

protected:
  ~Base() = default;
};

void CallsF(Base& base);
// CallsF is not going to own "base" (i.e. call "delete &base;").
// It will only call Base::f() so it doesn't need to access Base::~Base.

//-------------------
// application.cpp

struct Derived : Base {
  void f() override { ... }
};

int main() {
  Derived derived;
  CallsF(derived);
  // No need for virtual destructor here as well.
}

$( this ).find( 'li.target' ).css("border", "3px double red");

or

$( this ).children( 'li.target' ).css("border", "3px double red");

Use children for immediate descendants, or find for deeper elements.

A MySQL answer adapted slightly from the MSDN example for MySqlDataReader.GetValues:

//assumes you've already created a connection, opened it, 
//and executed a query to a reader

while(reader.Read())
{
    Object[] values = new Object[reader.FieldCount];
    int fieldCount = reader.GetValues(values);

    Console.WriteLine("\nreader.GetValues retrieved {0} columns.",   fieldCount);
    for (int i = 0; i < fieldCount; i++)
        Console.WriteLine(values[i]);
}

Using MySqlDataReader.FieldCount will allow you to retrieve the number of columns in the row you've queried.

An Essay way :

public class CharToInt{  
public static void main(String[] poo){  
String ss="toyota";
for(int i=0;i<ss.length();i++)
  {
     char c = ss.charAt(i); 
    // int a=c;  
     System.out.println(c); } } 
}

android:ellipsize added in API Level 1. An ellipsis is three periods in a row. (...) .

In your Xml

 <TextView
       ....
       android:text="Hi I am Amiyo, you can see how to ellipse works."
       android:ellipsize = "end"  
   />

At this point, the ellipsis will not display yet as a TextView is set to automatically expand on default when new text is entered. You will need to limit the TextView in some way. Do do this, you can use either add to your TextView a scrollHorizontally, minLines, or maxLines to have the ellipsis display.

To make the ellipse:

    at the end: this is how it would.   
    use: android:ellipsize = "end"

And

 in the middle:
 use: android:ellipsize = "middle"

And

 at the start:
 use: android:ellipsize = "start"

And

 to have no ellipse
 use: android:ellipsize = "none"

Note Please :

Do not use android:singeLine = "true", it is deprecated.
android:maxLines = "1" will not display the three dots (...)
android:lines = "1" will not display the three dots (...)

For more details you can visit here

driver.findElement(By.id("invoice_supplier_id")).setAttribute("value", "your value");

To give you a better understanding of why this happens, I'd like to expand upon @r-samuel-klatchko's answer a bit.

When you call malloc, what is really happening is a bit more complicated than just giving you a chunk of memory to play with. Under the hood, malloc also keeps some housekeeping information about the memory it has given you (most importantly, its size), so that when you call free, it knows things like how much memory to free. This information is commonly kept right before the memory location returned to you by malloc. More exhaustive information can be found on the internet™, but the (very) basic idea is something like this:

+------+-------------------------------------------------+
+ size |                  malloc'd memory                +
+------+-------------------------------------------------+
       ^-- location in pointer returned by malloc

Building on this (and simplifying things greatly), when you call malloc, it needs to get a pointer to the next part of memory that is available. One very simple way of doing this is to look at the previous bit of memory it gave away, and move size bytes further down (or up) in memory. With this implementation, you end up with your memory looking something like this after allocating p1, p2 and p3:

+------+----------------+------+--------------------+------+----------+
+ size |                | size |                    | size |          +
+------+----------------+------+--------------------+------+----------+
       ^- p1                   ^- p2                       ^- p3

So, what is causing your error?

Well, imagine that your code erroneously writes past the amount of memory you've allocated (either because you allocated less than you needed as was your problem or because you're using the wrong boundary conditions somewhere in your code). Say your code writes so much data to p2 that it starts overwriting what is in p3's size field. When you now next call malloc, it will look at the last memory location it returned, look at its size field, move to p3 + size and then start allocating memory from there. Since your code has overwritten size, however, this memory location is no longer after the previously allocated memory.

Needless to say, this can wreck havoc! The implementors of malloc have therefore put in a number of "assertions", or checks, that try to do a bunch of sanity checking to catch this (and other issues) if they are about to happen. In your particular case, these assertions are violated, and thus malloc aborts, telling you that your code was about to do something it really shouldn't be doing.

As previously stated, this is a gross oversimplification, but it is sufficient to illustrate the point. The glibc implementation of malloc is more than 5k lines, and there have been substantial amounts of research into how to build good dynamic memory allocation mechanisms, so covering it all in a SO answer is not possible. Hopefully this has given you a bit of a view of what is really causing the problem though!

All the answers I tested here (about half) think 2000-02-29 to 2001-02-28 is zero years, when it most likely should be 1 since 2000-02-29 to 2001-03-01 is 1 year and 1 day. Here is a getYearDiff function that fixes that. It only works where d0 < d1:

function getYearDiff(d0, d1) {

    d1 = d1 || new Date();

    var m = d0.getMonth();
    var years = d1.getFullYear() - d0.getFullYear();

    d0.setFullYear(d0.getFullYear() + years);

    if (d0.getMonth() != m) d0.setDate(0);

    return d0 > d1? --years : years;
}

I set permissions to:

    # Set all files and directories user and group to wp-user
    chown wp-user:wp-user -R *

    # Set uploads folder user and group to www-data
    chown www-data:www-data -R wp-content/uploads/

    # Set all directories permissions to 755
    find . -type d -exec chmod 755 {} \;

    # Set all files permissions to 644
    find . -type f -exec chmod 644 {} \;

In my case I created a specific user for WordPress which is different from the apache default user that prevent access from the web to those files owned by that user.

Then it gives permission to apache user to handle the upload folder and finally set secure enough file and folder permissions.

EDITED

If you're using W3C Total Cache you should do the next also:

rm -rf wp-content/cache/config
rm -rf wp-content/cache/object
rm -rf wp-content/cache/db
rm -rf wp-content/cache/minify
rm -rf wp-content/cache/page_enhanced

Then it'll work!

EDITED

After a while developing WordPress sites I'd recommend different file permissions per environment:

In production, I wouldn't give access to users to modify the filesystem, I'll only allow them to upload resources and give access to some plugins specific folders to do backups, etc. But managing projects under Git and using deploy keys on the server, it isn't good update plugins on staging nor production. I leave here the production file setup:

# Set uploads folder user and group to www-data
chown www-data:www-data -R wp-content/uploads/

www-data:www-data = apache or nginx user and group

Staging will share the same production permissions as it should be a clone of it.

Finally, development environment will have access to update plugins, translations, everything...

# Set uploads folder user and group to www-data
chown www-data:www-data -R wp-content/

# Set uploads folder user and group to www-data
chown your-user:root-group -R wp-content/themes

# Set uploads folder user and group to www-data
chown your-user:root-group -R wp-content/plugins/your-plugin

www-data:www-data = apache or nginx user and group your-user:root-group = your current user and the root group

These permissions will give you access to develop under themes and your-plugin folder without asking permission. The rest of the content will be owned by the Apache or Nginx user to allow WP to manage the filesystem.

Before creating a git repo first run these commands:

# Set all directories permissions to 755
find . -type d -exec chmod 755 {} \;

# Set all files permissions to 644
find . -type f -exec chmod 644 {} \;

I tried mipadi's answer and comments on playground. And thought of sharing it. Here you go. I think mipadi's answer should be mark as accepted.

class A{
    class func classFunction(){
    }
    static func staticFunction(){
    }
    class func classFunctionToBeMakeFinalInImmediateSubclass(){
    }
}

class B: A {
    override class func classFunction(){

    }

    //Compile Error. Class method overrides a 'final' class method
    override static func staticFunction(){

    }

    //Lets avoid the function called 'classFunctionToBeMakeFinalInImmediateSubclass' being overriden by subclasses

    /* First way of doing it
    override static func classFunctionToBeMakeFinalInImmediateSubclass(){
    }
    */

    // Second way of doing the same
    override final class func classFunctionToBeMakeFinalInImmediateSubclass(){
    }

    //To use static or final class is choice of style.
    //As mipadi suggests I would use. static at super class. and final class to cut off further overrides by a subclass
}

class C: B{
    //Compile Error. Class method overrides a 'final' class method
    override static func classFunctionToBeMakeFinalInImmediateSubclass(){

    }
}

Here are 3 examples:

$(document).on('click', 'ul li a', function (e) {_x000D_
    e.preventDefault();_x000D_
_x000D_
    var example1 = $(this).parents('ul:first').attr('id');_x000D_
    $('#results').append('<p>Result from example 1: <strong>' + example1 + '</strong></p>');_x000D_
_x000D_
    var example2 = $(this).parents('ul:eq(0)').attr('id');_x000D_
    $('#results').append('<p>Result from example 2: <strong>' + example2 + '</strong></p>');_x000D_
  _x000D_
    var example3 = $(this).closest('ul').attr('id');_x000D_
    $('#results').append('<p>Result from example 3: <strong>' + example3 + '</strong></p>');_x000D_
  _x000D_
  _x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_

</ul>_x000D_
_x000D_
<div id="results">_x000D_
  <h1>Results:</h1>_x000D_
</div>

Let me know whether it was helpful.

After doing some search i got solution from android developer guide

PendingIntent contentIntent ;
Intent intent = new Intent(this,TestActivity.class);
intent.putExtra("extra","Test");
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);

stackBuilder.addParentStack(ArticleDetailedActivity.class);

contentIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);

To Get Intent extra value in Test Activity class you need to write following code :

 Intent intent = getIntent();
 String extra = intent.getStringExtra("extra") ;

For that particular case you can use:

.detail_container > ul + h1{ 
    color: blue; 
}

But if you need that same selector on many cases, you should have a class for those, like BoltClock said.

A variation of the function provided by Paolo Bergantino that works directly on String:

String.prototype.addSlashes = function() 
{ 
   //no need to do (str+'') anymore because 'this' can only be a string
   return this.replace(/[\\"']/g, '\\$&').replace(/\u0000/g, '\\0');
} 

By adding the code above in your library you will be able to do:

var test = "hello single ' double \" and slash \\ yippie";
alert(test.addSlashes());

EDIT:

Following suggestions in the comments, whoever is concerned about conflicts amongst JavaScript libraries can add the following code:

if(!String.prototype.addSlashes)
{
   String.prototype.addSlashes = function()... 
}
else
   alert("Warning: String.addSlashes has already been declared elsewhere.");

Here lies your problem:

private void fillTextView (int id, String text) {
    TextView tv = (TextView) findViewById(id);
    tv.setText(text); // tv is null
}

--> (TextView) findViewById(id); // returns null But from your code, I can't find why this method returns null. Try to track down, what id you give as a parameter and if this view with the specified id exists.

The error message is very clear and even tells you at what method. From the documentation:

public final View findViewById (int id)
    Look for a child view with the given id. If this view has the given id, return this view.
    Parameters
        id  The id to search for.
    Returns
        The view that has the given id in the hierarchy or null

http://developer.android.com/reference/android/view/View.html#findViewById%28int%29

In other words: You have no view with the id you give as a parameter.

I got this when pulling into an Rstudio project. I realised I forgot to do:

sudo rstudio

on program startup. In fact as there's another bug I've got, I need to actually do:

sudo rstudio --no-sandbox

Just by using select select you can select particular columns, give them readable names and cast them. For example like this:

spark.read.csv(path).select(
          '_c0.alias("stn").cast(StringType),
          '_c1.alias("wban").cast(StringType),
          '_c2.alias("lat").cast(DoubleType),
          '_c3.alias("lon").cast(DoubleType)
        )
          .where('_c2.isNotNull && '_c3.isNotNull && '_c2 =!= 0.0 && '_c3 =!= 0.0)

I had the same problem when I upgraded jquery UI to 1.8.1 without upgrading the corresponding theme. Only is needed to upgrade the theme too and "auto" works again.

template<typename T>
string str(T begin, T end)
{
    stringstream ss;
    bool first = true;
    for (; begin != end; begin++)
    {
        if (!first)
            ss << ", ";
        ss << *begin;
        first = false;
    }
    return ss.str();
}

This is the str function that can make integers turn into a string and not into a char for what the integer represents. Also works for doubles.

I would suggest you to write extension, something like below.

public static class WriteToConsoleExtension
{
   // Extension to all types
   public static void WriteToConsole(this object instance, 
                                     string format, 
                                     params object[] data)
   {
       Console.WriteLine(format, data);
   }
}

class Program
{
    static void Main(string[] args)
    {
        Program p = new Program();
        // Usage of extension
        p.WriteToConsole("Test {0}, {1}", DateTime.Now, 1);
    }
}

Hope this helps (and not too late :) )

Try this:

date("H:i:s",-57600 + 685);

No need to create a GD resource, as someone else suggested.

$input = 'http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com';
$output = 'google.com.jpg';
file_put_contents($output, file_get_contents($input));

Note: this solution only works if you're setup to allow fopen access to URLs. If the solution above doesn't work, you'll have to use cURL.

Use Map to remove the duplicates. (For new readers)

var standardsList = [
    {"Grade": "Math K", "Domain": "Counting & Cardinality"},
    {"Grade": "Math K", "Domain": "Counting & Cardinality"},
    {"Grade": "Math K", "Domain": "Counting & Cardinality"},
    {"Grade": "Math K", "Domain": "Counting & Cardinality"},
    {"Grade": "Math K", "Domain": "Geometry"},
    {"Grade": "Math 1", "Domain": "Counting & Cardinality"},
    {"Grade": "Math 1", "Domain": "Counting & Cardinality"},
    {"Grade": "Math 1", "Domain": "Orders of Operation"},
    {"Grade": "Math 2", "Domain": "Geometry"},
    {"Grade": "Math 2", "Domain": "Geometry"}
];

var grades = new Map();
standardsList.forEach( function( item ) {
    grades.set(JSON.stringify(item), item);
});

console.log( [...grades.values()]);

/*

  { Grade: 'Math K', Domain: 'Counting & Cardinality' },
  { Grade: 'Math K', Domain: 'Geometry' },
  { Grade: 'Math 1', Domain: 'Counting & Cardinality' },

  { Grade: 'Math 2', Domain: 'Geometry' }
]
*/

Then just Select:

var list = source.Select(s=>new { ID = s.ID, Name = s.Name }).ToList();

(edit) Actually - the names could be inferred in this case, so you could use:

var list = source.Select(s=>new { s.ID, s.Name }).ToList();

which saves a few electrons...

The M2_HOME environment variable for the global one. See Settings Reference:

The settings element in the settings.xml file contains elements used to define values which configure Maven execution in various ways, like the pom.xml, but should not be bundled to any specific project, or distributed to an audience. These include values such as the local repository location, alternate remote repository servers, and authentication information. There are two locations where a settings.xml file may live:

• The Maven install: $M2_HOME/conf/settings.xml
• A user's install: ${user.home}/.m2/settings.xml

No, you don't have to include all of POI's dependencies. Maven's transitive dependency mechanism will take care of that. As noted you just have to express a dependency on the appropriate POI artifact. For example:

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>3.8-beta4</version>
</dependency>

Edit(UPDATE): I don't know about previous versions but to resolve imports to XSSFWorkbook and other classes in org.apache.poi package you need to add dependency for poi-ooxml too. The dependencies will be:

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>4.1.2</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>4.1.2</version>
</dependency>

Maybe not the fastest, but certainly pretty readable:

function findLongestWord(array) {
  var longestWord = "";

  array.forEach(function(word) {
    if(word.length > longestWord.length) {
      longestWord = word;
    }
  });

  return longestWord;
}

var word = findLongestWord(["The","quick","brown", "fox", "jumped", "over", "the", "lazy", "dog"]);
console.log(word); // result is "jumped"

The array function forEach has been supported since IE9+.

I think it works the other way

<#if object.attribute??>
   Do whatever you want....
</#if>

If object.attribute is NOT NULL, then the content will be printed.

For properties for which css transition will affect, can use transitionend event, example for z-index:

$(".observed-element").on("webkitTransitionEnd transitionend", function(e) {_x000D_
  console.log("end", e);_x000D_
  alert("z-index changed");_x000D_
});_x000D_
_x000D_
$(".changeButton").on("click", function() {_x000D_
  console.log("click");_x000D_
  document.querySelector(".observed-element").style.zIndex = (Math.random() * 1000) | 0;_x000D_
});

.observed-element {_x000D_
  transition: z-index 1ms;_x000D_
  -webkit-transition: z-index 1ms;_x000D_
}_x000D_

sizeof(buffer) is the size of a pointer on your last line NOT the actual size of the buffer. You need to use "length" that you already established instead

netstat -ano|grep 443|grep LISTEN

will tell you whether a process is listening on port 443 (you might have to replace LISTEN with a string in your language, though, depending on your system settings).

I think a better way is to create some predicate methods. This will also save your "Single Point of Control".

class Object
 def is_string?
   false
 end
end

class String
 def is_string?
   true
 end
end

print "test".is_string? #=> true
print 1.is_string?      #=> false

The more duck typing way ;)

String.split(String regex) is convenient but if you don't need the regular expression handling then go with the substring(..) example, java.util.StringTokenizer or use Apache commons lang 1. The performance difference when not using regular expressions can be a gain of 1 to 2 orders of magnitude in speed.

You have to run a web server (e.g. Apache) and browse to your localhost, mostly likely on port 80.

What you really ought to do is install an all-in-one package like XAMPP, it bundles Apache, MySQL PHP, and Perl (if you were so inclined) as well as a few other tools that work with Apache and MySQL - plus it's cross platform (that's what the 'X' in 'XAMPP' stands for).

Once you install XAMPP (and there is an installer, so it shouldn't be hard) open up the control panel for XAMPP and then click the "Start" button next to Apache - note that on applications that require a database, you'll also need to start MySQL (and you'll be able to interface with it through phpMyAdmin). Once you've started Apache, you can browse to http://localhost.

Again, regardless of whether or not you choose XAMPP (which I would recommend), you should just have to start Apache.

It worked for me when I called CancelCallBacks(this) inside the post delayed runnable by handing it via a boolean

Runnable runnable = new Runnable(){
    @Override
    public void run() {
        Log.e("HANDLER", "run: Outside Runnable");
        if (IsRecording) {
            Log.e("HANDLER", "run: Runnable");
            handler.postDelayed(this, 2000);
        }else{
            handler.removeCallbacks(this);
        }
    }
};

Everyone else has already answered it, but I think I still have something else to add.

Reasons to have that if statement calling main() (in no particular order):

• Other languages (like C and Java) have a main() function that is called when the program is executed. Using this if, we can make Python behave like them, which feels more familiar for many people.

• Code will be cleaner, easier to read, and better organized. (yeah, I know this is subjective)

• It will be possible to import that python code as a module without nasty side-effects.

• This means it will be possible to run tests against that code.

• This means we can import that code into an interactive python shell and test/debug/run it.

• Variables inside def main are local, while those outside it are global. This may introduce a few bugs and unexpected behaviors.

But, you are not required to write a main() function and call it inside an if statement.

I myself usually start writing small throwaway scripts without any kind of function. If the script grows big enough, or if I feel putting all that code inside a function will benefit me, then I refactor the code and do it. This also happens when I write bash scripts.

Even if you put code inside the main function, you are not required to write it exactly like that. A neat variation could be:

import sys

def main(argv):
    # My code here
    pass

if __name__ == "__main__":
    main(sys.argv)

This means you can call main() from other scripts (or interactive shell) passing custom parameters. This might be useful in unit tests, or when batch-processing. But remember that the code above will require parsing of argv, thus maybe it would be better to use a different call that pass parameters already parsed.

In an object-oriented application I've written, the code looked like this:

class MyApplication(something):
    # My code here

if __name__ == "__main__":
    app = MyApplication()
    app.run()

So, feel free to write the code that better suits you. :)

To add tab names while exporting to excel, I used the following method:

• On the report design window, select the tablix object.
• Open properties window of the tablix object.
• Add the required tab name to the PageName property.
• Run the report
• Export the report to Excel.
• Now the worksheet name is the same as the PageName property of the tablix object.

You could try Ladon. It serves up multiple web server protocols at once so you can offer more flexibility at the client side.

http://pypi.python.org/pypi/ladon

  with cttmp
  as
  (
  select Col_Name, count(*) as ctn from tab_name group by Col_Name having count(Col_Name)>1
  )
  select sum(ctn) from c

Try adding this:

$.ajax({
    url: "ajax.aspx",
    type:'get',
    data: {ajaxid:4, UserID: UserID , EmailAddress: encodeURIComponent(EmailAddress)},
    dataType: 'json',
    success: function(response) {
      //Do Something
    },
    error: function(xhr) {
    //Do Something to handle error
    }
});

Depends on what datatype is expected, you can assign html, json, script, xml

Another way on the command line if you are using ant is to use the android.bat script (Windows) or android script (Mac). It's in $SDK_DIR/tools.

If you say,

android.bat update project --path .  --target "android-8"

it will regenerate your build.xml, AndroidManifest.xml, etc.

titleForHeaderInSection is a delegate method of UITableView so to apply header text of section write as follows,

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{
              return @"Hello World";
}

Java uses double quotes for "String" and single quotes for 'C'haracters.

We can't say that it is possible of not their is some other way exist to perform update operation in user-defined Function. Directly DML is not possible in UDF it is for sure.

Below Query is working perfectly:

create table testTbl
(
id int identity(1,1) Not null,
name nvarchar(100)
)
GO

insert into testTbl values('ajay'),('amit'),('akhil')
Go

create function tblValued()
returns Table
as
return (select * from testTbl where id = 1)
Go

update tblValued() set name ='ajay sharma' where id = 1
Go

select * from testTbl 
Go

According to w3schools: http://www.w3schools.com/cssref/css3_pr_transform.asp

The transform property is supported in Internet Explorer 10, Firefox, and Opera. Internet Explorer 9 supports an alternative, the -ms-transform property (2D transforms only). Safari and Chrome support an alternative, the -webkit-transform property (3D and 2D transforms). Opera supports 2D transforms only.

This is a 2D transform, so it should work, with the vendor prefixes, on Chrome, Firefox, Opera, Safari, and IE9+.

Other answers used :before to stop it from flipping the inner content. I used this on my footer (to vertically-mirror the image from my header):

HTML:

<footer>
<p><a href="page">Footer Link</a></p>
<p>&copy; 2014 Company</p>
</footer>

CSS:

footer {
background:url(/img/headerbg.png) repeat-x 0 0;

/* flip background vertically */
-webkit-transform:scaleY(-1);
-moz-transform:scaleY(-1);
-ms-transform:scaleY(-1);
-o-transform:scaleY(-1);
transform:scaleY(-1);
}

/* undo the vertical flip for all child elements */
footer * {
-webkit-transform:scaleY(-1);
-moz-transform:scaleY(-1);
-ms-transform:scaleY(-1);
-o-transform:scaleY(-1);
transform:scaleY(-1);
}

So you end up flipping the element and then re-flipping all its children. Works with nested elements, too.

Tkinter should come with the latest Python, I don't think it comes with Python2. I had the same problem but once. I upgraded to Python 3.8 Tkinter was installed.

What you can do is @Autowired a setter method and have it set a new static field.

public class Boo {
    @Autowired
    Foo foo;

    static Foo staticFoo;   

    @Autowired
    public void setStaticFoo(Foo foo) {
        Boo.staticFoo = foo;
    }

    public static void randomMethod() {
         staticFoo.doStuff();
    }
}

When the bean gets processed, Spring will inject a Foo implementation instance into the instance field foo. It will then also inject the same Foo instance into the setStaticFoo() argument list, which will be used to set the static field.

This is a terrible workaround and will fail if you try to use randomMethod() before Spring has processed an instance of Boo.

when you want to access images which are in public/images folder and if you want to access it without using laravel functions, use as follows:

<img src={{url('/images/photo.type')}} width="" height="" alt=""/>

This works fine.

I had this problem when I added the group of the login user to another user.

Let's say there is an SSH-login user called userA and a non-SSH-login user userB. userA has the group userA as well. I modified userB to have the group userA as well. The lead to the the described behaviour, so that userA was not able to login without a prompt.

After I removed the group userA from userB, the login without a prompt worked again.

Another python example (based on THE answer):

def isrotation(s1,s2):
     return len(s1)==len(s2) and s1 in 2*s2

Simple like this:

import math
def my_cdf(x):
    return 0.5*(1+math.erf(x/math.sqrt(2)))

From this brilliant blog post... https://blog.josephscott.org/2011/10/14/timing-details-with-curl/

cURL supports formatted output for the details of the request (see the cURL manpage for details, under -w, –write-out <format>). For our purposes we’ll focus just on the timing details that are provided. Times below are in seconds.

1. Create a new file, curl-format.txt, and paste in:

        time_namelookup:  %{time_namelookup}s\n
           time_connect:  %{time_connect}s\n
        time_appconnect:  %{time_appconnect}s\n
       time_pretransfer:  %{time_pretransfer}s\n
          time_redirect:  %{time_redirect}s\n
     time_starttransfer:  %{time_starttransfer}s\n
                        ----------\n
             time_total:  %{time_total}s\n
   

2. Make a request:

    curl -w "@curl-format.txt" -o /dev/null -s "http://wordpress.com/"
   

Or on Windows, it's...

    curl -w "@curl-format.txt" -o NUL -s "http://wordpress.com/"

What this does:

-w "@curl-format.txt" tells cURL to use our format file
-o /dev/null redirects the output of the request to /dev/null
-s tells cURL not to show a progress meter
"http://wordpress.com/" is the URL we are requesting. Use quotes particularly if your URL has "&" query string parameters

And here is what you get back:

   time_namelookup:  0.001s
      time_connect:  0.037s
   time_appconnect:  0.000s
  time_pretransfer:  0.037s
     time_redirect:  0.000s
time_starttransfer:  0.092s
                   ----------
        time_total:  0.164s

Make a Linux/Mac shortcut (alias)

alias curltime="curl -w \"@$HOME/.curl-format.txt\" -o /dev/null -s "

Then you can simply call...

curltime wordpress.org

Thanks to commenter Pete Doyle!

Make a Linux/Mac stand-alone script

This script does not require a separate .txt file to contain the formatting.

Create a new file, curltime, somewhere in your executable path, and paste in:

#!/bin/bash

curl -w @- -o /dev/null -s "$@" <<'EOF'
    time_namelookup:  %{time_namelookup}\n
       time_connect:  %{time_connect}\n
    time_appconnect:  %{time_appconnect}\n
   time_pretransfer:  %{time_pretransfer}\n
      time_redirect:  %{time_redirect}\n
 time_starttransfer:  %{time_starttransfer}\n
                    ----------\n
         time_total:  %{time_total}\n
EOF

Call the same way as the alias:

curltime wordpress.org

Make a Windows shortcut (aka BAT file)

Put this command in CURLTIME.BAT (in the same folder as curl.exe)

curl -w "@%~dp0curl-format.txt" -o NUL -s %*

Then you can simply call...

curltime wordpress.org

I use JAD Decompiler.

There is an Eclipse plugin for it, jadeclipse. It is pretty nice.

The functions in stdlib.h and stdio.h have implementations in libc.so (or libc.a for static linking), which is linked into your executable by default (as if -lc were specified). GCC can be instructed to avoid this automatic link with the -nostdlib or -nodefaultlibs options.

The math functions in math.h have implementations in libm.so (or libm.a for static linking), and libm is not linked in by default. There are historical reasons for this libm/libc split, none of them very convincing.

Interestingly, the C++ runtime libstdc++ requires libm, so if you compile a C++ program with GCC (g++), you will automatically get libm linked in.

Definitely the second one. In the first one, you use a constant empty List<?> and then convert it to a File[], which requires to create an empty File[0] array. And that is what you do in the second one in one single step.

I use [^\t\r\n\x20-\x7E]+ and that seems to be working fine.

Old GCC Extension: Operators <?, >?, <?=, >?=

In a very old version of GCC there were the operators <?, >? (see here, here it was in C++ but I think it also applied as a C extension back then) I have also seen the operators <?=, >?= corresponding to the assignment statements.

The operands were evaluated once and even allowed for a very short assignment statement. Its very short compared to common min/max assignments. There is nothing that can top this.

Those were a shorthand for the following:

min(a, b)   ===   a < b ? a : b   ===   a <? b;
max(a, b)   ===   a > b ? a : b   ===   a >? b;
a = min(a, b);   ===   if(b < a) a = b;   ===   a <?= b;
a = max(a, b);   ===   if(b > a) a = b;   ===   a >?= b;

Finding the minimum is very concise:

int find_min(const int* ints, int num_ints)
{
    assert(num_ints > 0);
    int min = ints[0];
    for(int i = 1; i < num_ints; ++i)
        min <?= ints[i];
    return min;
}

I hope this might be some day brought back to GCC, because I think these operators are genious.

Not so hard:

#include <thread>

void Test::runMultiThread()
{
    std::thread t1(&Test::calculate, this,  0, 10);
    std::thread t2(&Test::calculate, this, 11, 20);
    t1.join();
    t2.join();
}

If the result of the computation is still needed, use a future instead:

#include <future>

void Test::runMultiThread()
{
     auto f1 = std::async(&Test::calculate, this,  0, 10);
     auto f2 = std::async(&Test::calculate, this, 11, 20);

     auto res1 = f1.get();
     auto res2 = f2.get();
}

Have a look at my related answer at

Designing a Test class for a custom Barrier

It's biased towards Java but has a reasonable summary of the options.

In summary though (IMO) its not the use of some fancy framework that will ensure correctness but how you go about designing you multithreaded code. Splitting the concerns (concurrency and functionality) goes a huge way towards raising confidence. Growing Object Orientated Software Guided By Tests explains some options better than I can.

Static analysis and formal methods (see, Concurrency: State Models and Java Programs) is an option but I've found them to be of limited use in commercial development.

Don't forget that any load/soak style tests are rarely guaranteed to highlight problems.

Good luck!

Link function only gets called once, so it would not directly do what you are expecting. You need to use angular $watch to watch a model variable.

This watch needs to be setup in the link function.

If you use isolated scope for directive then the scope would be

scope :{typeId:'@' }

In your link function then you add a watch like

link: function(scope, element, attrs) {
    scope.$watch("typeId",function(newValue,oldValue) {
        //This gets called when data changes.
    });
 }

If you are not using isolated scope use watch on some_prop

Just one line will be OK.

cat "`dirname $0`"/../some.txt

The difference is in the line below to "because in that way there is no overhead of calling a function."

array_push() will raise a warning if the first argument is not an array. This differs from the $var[] behaviour where a new array is created.

This is a quick hacky way: ls -lart | grep -v ^total.

Basically, remove any lines that start with "total", which in ls output should only be the first line.

A more general way (for anything):

ls -lart | sed "1 d"

sed "1 d" means only print everything but first line.

?? The accepted solution is flawed.

Here are two scenarios where the keyup event will not get fired:

1. The user drags text into the textarea.
2. The user copy-paste text in the textarea with a right click (contextual menu).

Use the HTML5 input event instead for a more robust solution:

<textarea maxlength='140'></textarea>

JavaScript (demo):

const textarea = document.querySelector("textarea");

textarea.addEventListener("input", event => {
    const target = event.currentTarget;
    const maxLength = target.getAttribute("maxlength");
    const currentLength = target.value.length;

    if (currentLength >= maxLength) {
        return console.log("You have reached the maximum number of characters.");
    }

    console.log(`${maxLength - currentLength} chars left`);
});

And if you absolutely want to use jQuery:

$('textarea').on("input", function(){
    var maxlength = $(this).attr("maxlength");
    var currentLength = $(this).val().length;

    if( currentLength >= maxlength ){
        console.log("You have reached the maximum number of characters.");
    }else{
        console.log(maxlength - currentLength + " chars left");
    }
});

git stash drop takes no parameter - which drops the top stash - or a stash reference which looks like: stash@{n} which n nominates which stash to drop. You can't pass a commit id to git stash drop.

git stash drop            # drop top hash, stash@{0}
git stash drop stash@{n}  # drop specific stash - see git stash list

Dropping a stash will change the stash@{n} designations of all stashes further down the stack.

I'm not sure why you think need to drop a stash because if you are using stash create a stash entry isn't created for your "stash" so there isn't anything to drop.

Here are some vendors you might me looking for

::-webkit-input-placeholder {color: tomato}
::-moz-placeholder          {color: tomato;} /* Firefox 19+ */
:-moz-placeholder           {color: tomato;} /* Firefox 18- */
:-ms-input-placeholder      {color: tomato;}

You can also style different states, such as focus

:focus::-webkit-input-placeholder {color: transparent}
:focus::-moz-placeholder          {color: transparent}
:focus:-moz-placeholder           {color: transparent}
:focus:-ms-input-placeholder      {color: transparent}

You can also do certain transitions on it, like

::-VENDOR-input-placeholder       {text-indent: 0px;   transition: text-indent 0.3s ease;}
:focus::-VENDOR-input-placeholder  {text-indent: 500px; transition: text-indent 0.3s ease;}

I have used

str.replace("'", "");

to replace the single quote in my string. Its working fine for me.

DNS resolving is usually done at the system level and not at the application level, so you can't normally have one program use one dns and another program use a different dns. I'm not aware of any firefox extensions that allow you to use a different dns.

To formalize some of the approaches laid out above:

Create a function that operates on the rows of your dataframe like so:

def f(row):
    if row['A'] == row['B']:
        val = 0
    elif row['A'] > row['B']:
        val = 1
    else:
        val = -1
    return val

Then apply it to your dataframe passing in the axis=1 option:

In [1]: df['C'] = df.apply(f, axis=1)

In [2]: df
Out[2]:
   A  B  C
a  2  2  0
b  3  1  1
c  1  3 -1

Of course, this is not vectorized so performance may not be as good when scaled to a large number of records. Still, I think it is much more readable. Especially coming from a SAS background.

Edit

Here is the vectorized version

df['C'] = np.where(
    df['A'] == df['B'], 0, np.where(
    df['A'] >  df['B'], 1, -1)) 

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

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

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

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

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

Another, more functional, way:

my_map = { 'a': 1, 'b':2 }
dict(map(reversed, my_map.items()))

To get rid of the outline when clicking, add outline:none

jsFiddle example

button {
    background-color: Transparent;
    background-repeat:no-repeat;
    border: none;
    cursor:pointer;
    overflow: hidden;
    outline:none;
}

button {_x000D_
    background-color: Transparent;_x000D_
    background-repeat:no-repeat;_x000D_
    border: none;_x000D_
    cursor:pointer;_x000D_
    overflow: hidden;_x000D_
    outline:none;_x000D_
}

<button>button</button>

Without any JS library or jQuery. To open a nice popup window if possible. Fails safely to normal link open.

<a href="https://acme.com/" onclick="onclick="openNewWindow(event, this.href);">...</a>

And the helper function:

function openNewWindow(event, location) {
  if (event.preventDefault && event.stopImmediatePropagation) { 
    event.preventDefault(); 
    event.stopImmediatePropagation(); 
  } else {
    event.returnValue = false; 
  }
  window.open(location, 'targetWindow', 'toolbar=no,location=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=800,height=450');
}

If you don't want to show controls then try this code

<audio  autoplay>
 <source src="song.ogg"  type="audio/ogg">
Your browser does not support the audio element.
</audio>

Solution posted by Denys S. in the question post:

I quite messed it up with c to c++ conversion (basically env variable stuff), but I got it working with the following code for C++:

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

jstring Java_the_package_MainActivity_getJniString( JNIEnv* env, jobject obj){

    jstring jstr = (*env)->NewStringUTF(env, "This comes from jni.");
    jclass clazz = (*env)->FindClass(env, "com/inceptix/android/t3d/MainActivity");
    jmethodID messageMe = (*env)->GetMethodID(env, clazz, "messageMe", "(Ljava/lang/String;)Ljava/lang/String;");
    jobject result = (*env)->CallObjectMethod(env, obj, messageMe, jstr);

    const char* str = (*env)->GetStringUTFChars(env,(jstring) result, NULL); // should be released but what a heck, it's a tutorial :)
    printf("%s\n", str);

    return (*env)->NewStringUTF(env, str);
}

And next code for java methods:

    public class MainActivity extends Activity {
    private static String LIB_NAME = "thelib";

    static {
        System.loadLibrary(LIB_NAME);
    }

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView tv = (TextView) findViewById(R.id.textview);
        tv.setText(this.getJniString());
    }

    // please, let me live even though I used this dark programming technique
    public String messageMe(String text) {
        System.out.println(text);
        return text;
    }

    public native String getJniString();
}

you try if You are in Master branch git commit -m "Commit message" -- filename.ext

An easy foolproof way to UNDO local file changes since the last commit is to place them in a new branch:

git branch changes
git checkout changes
git add .
git commit

This leaves the changes in the new branch. Return to the original branch to find it back to the last commit:

git checkout master

The new branch is a good place to practice different ways to revert changes without risk of messing up the original branch.

An Easy Approach...

system("Color F0");

Letter Represents Background Color while the number represents the text color.

0 = Black

1 = Blue

2 = Green

3 = Aqua

4 = Red

5 = Purple

6 = Yellow

7 = White

8 = Gray

9 = Light Blue

A = Light Green

B = Light Aqua

C = Light Red

D = Light Purple

E = Light Yellow

F = Bright White

Use below code to print the error code :

echo mysqli_errno($this->db_link);

Error code will give you better idea about the error.

I don't think your question is very clear, this code assumes that if you're going to include the -domain parameter, it's always 'named' (i.e. dostuff computername arg2 -domain domain); this also makes the computername parameter mandatory.

Function DoStuff(){
    param(
        [Parameter(Mandatory=$true)][string]$computername,
        [Parameter(Mandatory=$false)][string]$arg2,
        [Parameter(Mandatory=$false)][string]$domain
    )
    if(!($domain)){
        $domain = 'domain1'
    }
    write-host $domain
    if($arg2){
        write-host "arg2 present... executing script block"
    }
    else{
        write-host "arg2 missing... exiting or whatever"
    }
}

You can try all you want to remove a package (and all the dependencies it brought in alongside) using unloadNamespace() but the memory footprint will still persist. And no, detach("package:,packageName", unload=TRUE, force = TRUE) will not work either.

From a fresh new console or Session > Restart R check memory with the pryr package:

If you have 300 columns as you mentioned in another comment, and you want to compare on all columns (assuming the columns are all the same name), you can use a NATURAL LEFT JOIN to implicitly join on all matching column names between the two tables so that you don't have to tediously type out all join conditions manually:

SELECT            a.*
FROM              tbl_1 a
NATURAL LEFT JOIN tbl_2 b
WHERE             b.FirstName IS NULL

Simple Kotlin Extension Solutions

Set all/any side independently:

fun View.setMargin(left: Int? = null, top: Int? = null, right: Int? = null, bottom: Int? = null) {
    val params = (layoutParams as? MarginLayoutParams)
    params?.setMargins(
            left ?: params.leftMargin,
            top ?: params.topMargin,
            right ?: params.rightMargin,
            bottom ?: params.bottomMargin)
    layoutParams = params
}

myView.setMargin(10, 5, 10, 5)
// or just any subset
myView.setMargin(right = 10, bottom = 5)

Directly refer to a resource values:

fun View.setMarginRes(@DimenRes left: Int? = null, @DimenRes top: Int? = null, @DimenRes right: Int? = null, @DimenRes bottom: Int? = null) {
    setMargin(
            if (left == null) null else resources.getDimensionPixelSize(left),
            if (top == null) null else resources.getDimensionPixelSize(top),
            if (right == null) null else resources.getDimensionPixelSize(right),
            if (bottom == null) null else resources.getDimensionPixelSize(bottom),
    )
}

myView.setMarginRes(top = R.dimen.my_margin_res)

To directly set all sides equally as a property:

var View.margin: Int
    get() = throw UnsupportedOperationException("No getter for property")
    set(@Px margin) = setMargin(margin, margin, margin, margin)
   
myView.margin = 10 // px

// or as res
var View.marginRes: Int
    get() = throw UnsupportedOperationException("No getter for property")
    set(@DimenRes marginRes) {
        margin = resources.getDimensionPixelSize(marginRes)
    }

myView.marginRes = R.dimen.my_margin_res

To directly set a specific side, you can create a property extension like this:

var View.leftMargin
    get() = marginLeft
    set(@Px leftMargin) = setMargin(left = leftMargin)

var View.leftMarginRes: Int
    get() = throw UnsupportedOperationException("No getter for property")
    set(@DimenRes leftMarginRes) {
        leftMargin = resources.getDimensionPixelSize(leftMarginRes)
    }

This allows you to make horizontal or vertical variants as well:

var View.horizontalMargin
    get() = throw UnsupportedOperationException("No getter for property")
    set(@Px horizontalMargin) = setMargin(left = horizontalMargin, right = horizontalMargin)

var View.horizontalMarginRes: Int
    get() = throw UnsupportedOperationException("No getter for property")
    set(@DimenRes horizontalMarginRes) {
        horizontalMargin = resources.getDimensionPixelSize(horizontalMarginRes)
    }

NOTE: If margin is failing to set, you may too soon before render, meaning params == null. Try wrapping the modification with myView.post{ margin = 10 }

I've had the same problem. The solution was to remove proxy from Chrome settings. Also you could have an extension that use proxy. Try to disable it.

You need to escape the backslash \:

println yourString.replace("\\", "/")

In info.plist

View controller-based status bar appearance NO
Status bar is initially hidden YES

In view controller.m

- (BOOL) prefersStatusBarHidden
{
    return YES;
}

To center a div, set it's width to some value and add margin: auto.

#partners .wrap {
    width: 655px;
    margin: auto;
}

EDIT, you want to center the div contents, not the div itself. You need to change display property of h2, ul and li to inline, and remove the float: left.

#partners li, ul, h2 {
    display: inline;
    float: none;
}

Then, they will be layed out like normal text elements, and aligned according to text-align property of their container, which is what you want.

If you do an "Add" it will add it to the bottom of the list. You need to do an "Insert" if you want the item added to the top of the list.

Here are TypeScript equivalents of some common .NET delegates:

interface Action<T>
{
    (item: T): void;
}

interface Func<T,TResult>
{
    (item: T): TResult;
}

Output when sorted

The definition of asarray is:

def asarray(a, dtype=None, order=None):
    return array(a, dtype, copy=False, order=order)

So it is like array, except it has fewer options, and copy=False. array has copy=True by default.

The main difference is that array (by default) will make a copy of the object, while asarray will not unless necessary.

It is easier with Kotlin using for-in loop:

for (childView in ll.children) {
     //childView is a child of ll         
}

Here ll is id of LinearLayout defined in layout XML.

One wrinkle I ran into (that isn't covered in other answers):

Suppose you have these namespaces:

• Something.Other
• Parent.Something.Other

When you use using Something.Other outside of a namespace Parent, it refers to the first one (Something.Other).

However if you use it inside of that namespace declaration, it refers to the second one (Parent.Something.Other)!

There is a simple solution: add the "global::" prefix: docs

namespace Parent
{
   using global::Something.Other;
   // etc
}

Using advanced wheres:

CabRes::where('m__Id', 46)
      ->where('t_Id', 2)
      ->where(function($q) {
          $q->where('Cab', 2)
            ->orWhere('Cab', 4);
      })
      ->get();

Or, even better, using whereIn():

CabRes::where('m__Id', 46)
      ->where('t_Id', 2)
      ->whereIn('Cab', $cabIds)
      ->get();

If you're googling this, and don't want the event listener to be an attribute, use:

document.getElementById('my-select').addEventListener('change', function() {_x000D_
  console.log('You selected: ', this.value);_x000D_
});

<select id="my-select">_x000D_
  <option value="1">One</option>_x000D_
  <option value="2">Two</option>_x000D_
  <option value="3">Three</option>_x000D_
</select>

In Python 3.6, set() now should keep the order, but there is another solution for Python 2 and 3:

>>> x = [1, 2, 20, 6, 210]
>>> sorted(set(x), key=x.index)
[1, 2, 20, 6, 210]

In java8+ this can be written in single line as follows:

collectionObjec.sort(comparator_lamda) or comparator.comparing(CollectionType::getterOfProperty)

code:

ListOfActiveAlarmObj.sort((a,b->a.getTimeStarted().compareTo(b.getTimeStarted())))
 

or

ListOfActiveAlarmObj.sort(Comparator.comparing(ActiveAlarm::getTimeStarted))

This has been covered here before.

The concept of first does not apply to object properties, and the order of a for...in loop is not guaranteed by the specs, however in practice it is reliably FIFO except critically for chrome (bug report). Make your decisions accordingly.

For Each row As DataRow In dtDataTable.Rows
    strDetail = row.Item("Detail")
Next row

There's also a shorthand:

For Each row As DataRow In dtDataTable.Rows
    strDetail = row("Detail")
Next row

Note that Microsoft's style guidelines for .Net now specifically recommend against using hungarian type prefixes for variables. Instead of "strDetail", for example, you should just use "Detail".

Take a look at this project it outputs some interesting stats about keyspaces based on regexs and prefixes. It uses the DEBUG OBJECT command and scans the db, identifying groups of keys and estimating the percentage of space they're taking up.

https://github.com/snmaynard/redis-audit

Output looks like this:

Summary  

---------------------------------------------------+--------------+-------------------+---------------------------------------------------  
Key                                                | Memory Usage | Expiry Proportion | Last Access Time                                    
---------------------------------------------------+--------------+-------------------+---------------------------------------------------  
notification_3109439                               | 88.14%       | 0.0%              | 2 minutes                               
user_profile_3897016                               | 11.86%       | 99.98%            | 20 seconds  
---------------------------------------------------+--------------+-------------------+---------------------------------------------------  

Or this this one: https://github.com/sripathikrishnan/redis-rdb-tools which does a full analysis on the entire keyspace by analyzing a dump.rdb file offline. This one works well also. It can give you the avg/min/max size for the entries in your db, and will even do it based on a prefix.

Just place "javascript:void(0)", in place of "#" in href tag

<a href="javascript:void(0);" onclick="callmymethod(24)">Call</a>

I had a similar requirement, but I wanted the n'th item in a particular group. This is how I solved it.

groups = data.groupby(['group_key'])
selection = groups['index_col'].apply(lambda x: x % 3 == 0)
subset = data[selection]

I think it has to do with your second element in storbinary. You are trying to open file, but it is already a pointer to the file you opened in line file = open(local_path,'rb'). So, try to use ftp.storbinary("STOR " + i, file).

This might not interest you but just to add (0:, I like VS2008 IDE for html editing - and it doubles the fun if you have internet explorer developer toolbar (like that of firebug).

In the spirit of functional programming, let's make our components a bit easier to work with by using abstractions.

// converts components into mappable functions
var mappable = function(component){
  return function(x, i){
    return component({key: i}, x);
  }
}

// maps on 2-dimensional arrays
var map2d = function(m1, m2, xss){
  return xss.map(function(xs, i, arr){
    return m1(xs.map(m2), i, arr);
  });
}

var td = mappable(React.DOM.td);
var tr = mappable(React.DOM.tr);
var th = mappable(React.DOM.th);

Now we can define our render like this:

render: function(){
  return (
    <table>
      <thead>{this.props.titles.map(th)}</thead>
      <tbody>{map2d(tr, td, this.props.rows)}</tbody>
    </table>
  );
}

jsbin

An alternative to our map2d would be a curried map function, but people tend to shy away from currying.

1D array of primitives does copy elements when it is cloned. This tempts us to clone 2D array(Array of Arrays).

Remember that 2D array clone doesn't work due to shallow copy implementation of clone().

public static void main(String[] args) {
    int row1[] = {0,1,2,3};
    int row2[] =  row1.clone();
    row2[0] = 10;
    System.out.println(row1[0] == row2[0]); // prints false

    int table1[][]={{0,1,2,3},{11,12,13,14}};
    int table2[][] = table1.clone();
    table2[0][0] = 100;
    System.out.println(table1[0][0] == table2[0][0]); //prints true
}

So I finally got it(http://jsfiddle.net/ncapito/eYtU5/):

.centerWrapper:before {
    content:'';
    height: 100%;
    display: inline-block;
    vertical-align: middle;
}

.center {
    display:inline-block;
    vertical-align: middle;
}

<div class='row'>
    <div class='login-icon'>
        <div class='centerWrapper'>
            <div class='center'> <i class='icon-user'></i></div>
       </div>
    </div>
    <input type="text" placeholder="Email" />
 </div>

Its a function that calls itself. Its useful for walking certain data structures that repeat themselves, such as trees. An HTML DOM is a classic example.

An example of a tree structure in javascript and a recursive function to 'walk' the tree.

    1
   / \
  2   3
     / \
    4   5

--

var tree = {
  id: 1,
  left: {
    id: 2,
    left: null,
    right: null
  },
  right: {
    id: 3,
    left: {
      id: 4,
      left: null,
      right: null
    },
    right: {
      id: 5,
      left: null,
      right: null
    }
  }
};

To walk the tree, we call the same function repeatedly, passing the child nodes of the current node to the same function. We then call the function again, first on the left node, and then on the right.

In this example, we'll get the maximum depth of the tree

var depth = 0;

function walkTree(node, i) {

  //Increment our depth counter and check
  i++;
  if (i > depth) depth = i;

  //call this function again for each of the branch nodes (recursion!)
  if (node.left != null) walkTree(node.left, i);
  if (node.right != null) walkTree(node.right, i);

  //Decrement our depth counter before going back up the call stack
  i--;
}

Finally we call the function

alert('Tree depth:' + walkTree(tree, 0));

A great way of understanding recursion is to step through the code at runtime.

simply type .\sqlexpress as the Server Name

I too needed a rounded ImageView, I used the below code, you can modify it accordingly:

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Bitmap.Config;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

public class RoundedImageView extends ImageView {

    public RoundedImageView(Context context) {
        super(context);
    }

    public RoundedImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public RoundedImageView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onDraw(Canvas canvas) {

        Drawable drawable = getDrawable();

        if (drawable == null) {
            return;
        }

        if (getWidth() == 0 || getHeight() == 0) {
            return;
        }
        Bitmap b = ((BitmapDrawable) drawable).getBitmap();
        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth();
        @SuppressWarnings("unused")
        int h = getHeight();

        Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
        canvas.drawBitmap(roundBitmap, 0, 0, null);

    }

    public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
        Bitmap sbmp;

        if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
            float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
            float factor = smallest / radius;
            sbmp = Bitmap.createScaledBitmap(bmp,
                    (int) (bmp.getWidth() / factor),
                    (int) (bmp.getHeight() / factor), false);
        } else {
            sbmp = bmp;
        }

        Bitmap output = Bitmap.createBitmap(radius, radius, Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final String color = "#BAB399";
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, radius, radius);

        paint.setAntiAlias(true);
        paint.setFilterBitmap(true);
        paint.setDither(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(Color.parseColor(color));
        canvas.drawCircle(radius / 2 + 0.7f, radius / 2 + 0.7f,
                radius / 2 + 0.1f, paint);
        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(sbmp, rect, rect, paint);

        return output;
    }

}

I can't answer the why part.

But if you want something dynamic then why don't you consider Collection ArrayList.

ArrrayList can be of any Object type.

And if as an compulsion you want it as an array you can use the toArray() method on it.

For example:

            ArrayList<String> al = new ArrayList<String>();
            al.add("one");
            al.add("two");
            String[] strArray = (String[]) al.toArray(new String[0]);

I hope this might help you.

I'd start by not calling it list, since that's the name of the constructor for Python's built in list type.

But once you've renamed it to cities or something, you'd do:

print(cities[0][0], cities[1][0])
print(cities[0][1], cities[1][1])

Ok i found a solution:

HTML:

<div class="styled-select">
    <select class="select-css">
        <option disabled selected></option>
        <option>Apples</option>
        <option>Bananas</option>
        <option>Grapes</option>
        <option>Oranges</option>
    </select>
    <span>How many kg's per week do you expect to be ordering</span>
</div>

CSS:

.styled-select select.select-css {
appearance: none;
   height: 80px;
   pointer-events:all;
   position:absolute;
   top:0;
   left:0;
}
.styled-select {
    position:relative;
    appearance: none;
    overflow: hidden;
    pointer-events:none;
   }

jQuery:

$(".select-css").on("change", function(){
    $(this).next('span').css('display', 'none');
});

#include<stdio.h>
#include<conio.h>
#include<math.h>

 else

j=0;
  while(j==0)
  {
   if(n%i==0)
   {j=1;
   n=n/i;
   }
   i=i+2;
  }
 i-=2;
 }
 }
return i;
 }

 void main()

  clock_t start = clock();
  long int n,sp;
  clrscr();
  printf("enter value of n");
  scanf("%ld",&n);
  sp=factor(n);
  printf("largest prime factor is %ld",sp);

  printf("Time elapsed: %f\n", ((double)clock() - start) / CLOCKS_PER_SEC);
  getch();
 }
