The python libs are obsolete with this function. I've done one that works correctly:

import os
import shutil

def copydirectorykut(src, dst):
    os.chdir(dst)
    list=os.listdir(src)
    nom= src+'.txt'
    fitx= open(nom, 'w')

    for item in list:
        fitx.write("%s\n" % item)

    fitx.close()

    f = open(nom,'r')
    for line in f.readlines():
        if "." in line:
            shutil.copy(src+'/'+line[:-1],dst+'/'+line[:-1])
        else:
            if not os.path.exists(dst+'/'+line[:-1]):
                os.makedirs(dst+'/'+line[:-1])
                copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
            copydirectorykut(src+'/'+line[:-1],dst+'/'+line[:-1])
    f.close()
    os.remove(nom)
    os.chdir('..')

Here is a version inspired by this thread that more closely mimics distutils.file_util.copy_file.

updateonly is a bool if True, will only copy files with modified dates newer than existing files in dst unless listed in forceupdate which will copy regardless.

ignore and forceupdate expect lists of filenames or folder/filenames relative to src and accept Unix-style wildcards similar to glob or fnmatch.

The function returns a list of files copied (or would be copied if dryrun if True).

import os
import shutil
import fnmatch
import stat
import itertools

def copyToDir(src, dst, updateonly=True, symlinks=True, ignore=None, forceupdate=None, dryrun=False):

    def copySymLink(srclink, destlink):
        if os.path.lexists(destlink):
            os.remove(destlink)
        os.symlink(os.readlink(srclink), destlink)
        try:
            st = os.lstat(srclink)
            mode = stat.S_IMODE(st.st_mode)
            os.lchmod(destlink, mode)
        except OSError:
            pass  # lchmod not available
    fc = []
    if not os.path.exists(dst) and not dryrun:
        os.makedirs(dst)
        shutil.copystat(src, dst)
    if ignore is not None:
        ignorepatterns = [os.path.join(src, *x.split('/')) for x in ignore]
    else:
        ignorepatterns = []
    if forceupdate is not None:
        forceupdatepatterns = [os.path.join(src, *x.split('/')) for x in forceupdate]
    else:
        forceupdatepatterns = []
    srclen = len(src)
    for root, dirs, files in os.walk(src):
        fullsrcfiles = [os.path.join(root, x) for x in files]
        t = root[srclen+1:]
        dstroot = os.path.join(dst, t)
        fulldstfiles = [os.path.join(dstroot, x) for x in files]
        excludefiles = list(itertools.chain.from_iterable([fnmatch.filter(fullsrcfiles, pattern) for pattern in ignorepatterns]))
        forceupdatefiles = list(itertools.chain.from_iterable([fnmatch.filter(fullsrcfiles, pattern) for pattern in forceupdatepatterns]))

            else:
                if not os.path.exists(directory) and dryrun is False:
                    os.makedirs(os.path.join(dst, dir))
                    shutil.copystat(src, dst)

                        go = True
                    if go is True:

                                shutil.copy2(s, d)
                else:

                    if not dryrun:
                        if os.path.islink(s) and symlinks is True:
                            copySymLink(s, d)

If the component is an EJB, then, there shouldn't be a problem injecting an EM.

But....In JBoss 5, the JAX-RS integration isn't great. If you have an EJB, you cannot use scanning and you must manually list in the context-param resteasy.jndi.resource. If you still have scanning on, Resteasy will scan for the resource class and register it as a vanilla JAX-RS service and handle the lifecycle.

This is probably the problem.

Yet another variation...

SELECT 
  Count(*) AS existFlag 
FROM 
  sys.columns 
WHERE 
  [name] = N 'ColumnName' 
  AND [object_id] = OBJECT_ID(N 'TableName')

I tested it by requesting my website (apache) with all available chars on my german keyboard as URL parameter:

http://example.com/?^1234567890ß´qwertzuiopü+asdfghjklöä#<yxcvbnm,.-°!"§$%&/()=? `QWERTZUIOPÜ*ASDFGHJKLÖÄ\'>YXCVBNM;:_²³{[]}\|µ@€~

These were not encoded:

^0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ,.-!/()=?`*;:_{}[]\|~

Not encoded after urlencode():

0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.-_

Not encoded after rawurlencode():

0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.-_~

Note: Before PHP 5.3.0 rawurlencode() encoded ~ because of RFC 1738. But this was replaced by RFC 3986 so its safe to use, now. But I do not understand why for example {} are encoded through rawurlencode() because they are not mentioned in RFC 3986.

An additional test I made was regarding auto-linking in mail texts. I tested Mozilla Thunderbird, aol.com, outlook.com, gmail.com, gmx.de and yahoo.de and they fully linked URLs containing these chars:

0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.-_~+#,%&=*;:@

Of course the ? was linked, too, but only if it was used once.

Some people would now suggest to use only the rawurlencode() chars, but did you ever hear that someone had problems to open these websites?

Asterisk
http://wayback.archive.org/web/*/http://google.com

Colon
https://en.wikipedia.org/wiki/Wikipedia:About

Plus
https://plus.google.com/+google

At sign, Colon, Comma and Exclamation mark
https://www.google.com/maps/place/USA/@36.2218457,...

Because of that these chars should be usable unencoded without problems. Of course you should not use &; because of encoding sequences like &. The same reason is valid for % as it used to encode chars in general. And = as it assigns a value to a parameter name.

Finally I would say its ok to use these unencoded:

0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ.-_~!+,*:@

But if you expect randomly generated URLs you should not use .!, because those mark the end of a sentence and some mail apps will not auto-link the last char of the url. Example:

Visit http://example.com/foo=bar! !

Renaming a worksheet manually in Excel, you hit a limit of 31 chars, so I'd suggest that that's a hard limit.

You just need to have a module that exports a history object. Then you would import that object throughout your project.

// history.js
import { createBrowserHistory } from 'history'

export default createBrowserHistory({
  /* pass a configuration object here if needed */
})

Then, instead of using one of the built-in routers, you would use the <Router> component.

// index.js
import { Router } from 'react-router-dom'
import history from './history'
import App from './App'

ReactDOM.render((
  <Router history={history}>
    <App />
  </Router>
), holder)

// some-other-file.js
import history from './history'
history.push('/go-here')

maybe that will help with windows scheduled tasks ...

var x = parseInt(455/10);

The parseInt() function parses a string and returns an integer.

The radix parameter is used to specify which numeral system to be used, for example, a radix of 16 (hexadecimal) indicates that the number in the string should be parsed from a hexadecimal number to a decimal number.

If the radix parameter is omitted, JavaScript assumes the following:

If the string begins with "0x", the radix is 16 (hexadecimal)
If the string begins with "0", the radix is 8 (octal). This feature is deprecated
If the string begins with any other value, the radix is 10 (decimal)

You can return FileResult with this methods:

1: Return FileStreamResult

    [HttpGet("get-file-stream/{id}"]
    public async Task<FileStreamResult> DownloadAsync(string id)
    {
        var fileName="myfileName.txt";
        var mimeType="application/...."; 
        var stream = await GetFileStreamById(id);

        return new FileStreamResult(stream, mimeType)
        {
            FileDownloadName = fileName
        };
    }

2: Return FileContentResult

    [HttpGet("get-file-content/{id}"]
    public async Task<FileContentResult> DownloadAsync(string id)
    {
        var fileName="myfileName.txt";
        var mimeType="application/...."; 
        var fileBytes = await GetFileBytesById(id);

        return new FileContentResult(fileBytes, mimeType)
        {
            FileDownloadName = fileName
        };
    }

I have found that using cabs(double), cabsf(float), cabsl(long double), __cabsf(float), __cabs(double), __cabsf(long double) is the solution

You could always do just:

a=[1,2,3]
b=['a','b']
c=[1,2,3,4]
d=[1,2,3]

a==b    #returns False
a==c    #returns False
a==d    #returns True

I have worked with a factory integrated with google maps autocomplete and promises made??, I hope you serve.

http://jsfiddle.net/the_pianist2/vL9nkfe3/1/

you only need to replace the autocompleteService by this request with $ http incuida being before the factory.

app.factory('Autocomplete', function($q, $http) {

and $ http request with

 var deferred = $q.defer();
 $http.get('urlExample').
success(function(data, status, headers, config) {
     deferred.resolve(data);
}).
error(function(data, status, headers, config) {
     deferred.reject(status);
});
 return deferred.promise;

<div ng-app="myApp">
  <div ng-controller="myController">
  <input type="text" ng-model="search"></input>
  <div class="bs-example">
     <table class="table" >
        <thead>
           <tr>
              <th>#</th>
              <th>Description</th>
           </tr>
        </thead>
        <tbody>
           <tr ng-repeat="direction in directions">
              <td>{{$index}}</td>
              <td>{{direction.description}}</td>
           </tr>
        </tbody>
     </table>
  </div>

'use strict';
 var app = angular.module('myApp', []);

  app.factory('Autocomplete', function($q) {
    var get = function(search) {
    var deferred = $q.defer();
    var autocompleteService = new google.maps.places.AutocompleteService();
    autocompleteService.getPlacePredictions({
        input: search,
        types: ['geocode'],
        componentRestrictions: {
            country: 'ES'
        }
    }, function(predictions, status) {
        if (status == google.maps.places.PlacesServiceStatus.OK) {
            deferred.resolve(predictions);
        } else {
            deferred.reject(status);
        }
    });
    return deferred.promise;
};

return {
    get: get
};
});

app.controller('myController', function($scope, Autocomplete) {
$scope.$watch('search', function(newValue, oldValue) {
    var promesa = Autocomplete.get(newValue);
    promesa.then(function(value) {
        $scope.directions = value;
    }, function(reason) {
        $scope.error = reason;
    });
 });

});

the question itself is to be made on:

deferred.resolve(varResult); 

when you have done well and the request:

deferred.reject(error); 

when there is an error, and then:

return deferred.promise;

Based on the answer by Learath2, here's what I did after doing git clone [...] and cd-ing into the created directory:

git branch -r | grep -v master | awk {print\$1} | sed 's/^origin\/\(.*\)$/\1 &/' | xargs -n2 git checkout -b

Worked for me but I can't know it'll work for you. Be careful.

STR_TO_DATE allows you to do this, and it has a format argument.

Based on @mat-khor's answer, I took the syswin su.exe, saved it as manufacture-syswin-su.exe, and wrote this wrapper script. It handles redirection of the command's stdout and stderr, so it can be used in a pipe, etc. Also, the script exits with the status of the given command.

Limitations:

• The syswin-su options are currently hardcoded to use the current user. Prepending env USERNAME=... to the script invocation overrides it. If other options were needed, the script would have to distinguish between syswin-su and command arguments, e.g. splitting at the first --.
• If the UAC prompt is cancelled or declined, the script hangs.

.

#!/bin/bash
set -e

# join command $@ into a single string with quoting (required for syswin-su)
cmd=$( ( set -x; set -- "$@"; ) 2>&1 | perl -nle 'print $1 if /\bset -- (.*)/' )

tmpDir=$(mktemp -t -d -- "$(basename "$0")_$(date '+%Y%m%dT%H%M%S')_XXX")
mkfifo -- "$tmpDir/out"
mkfifo -- "$tmpDir/err"

cat >> "$tmpDir/script" <<-SCRIPT
    #!/bin/env bash
    $cmd > '$tmpDir/out' 2> '$tmpDir/err'
    echo \$? > '$tmpDir/status'
SCRIPT

chmod 700 -- "$tmpDir/script"

manufacture-syswin-su -s bash -u "$USERNAME" -m -c "cygstart --showminimized bash -c '$tmpDir/script'" > /dev/null &
cat -- "$tmpDir/err" >&2 &
cat -- "$tmpDir/out"
wait $!
exit $(<"$tmpDir/status")

Here's a function that takes a path/filename as a string and returns the extension as a string. It is all standard c++, and should work cross-platform for most platforms.

Unlike several other answers here, it handles the odd cases that windows' PathFindExtension handles, based on PathFindExtensions's documentation.

wstring get_file_extension( wstring filename )
{
    size_t last_dot_offset = filename.rfind(L'.');
    // This assumes your directory separators are either \ or /
    size_t last_dirsep_offset = max( filename.rfind(L'\\'), filename.rfind(L'/') );

    // no dot = no extension
    if( last_dot_offset == wstring::npos )
        return L"";

    // directory separator after last dot = extension of directory, not file.
    // for example, given C:\temp.old\file_that_has_no_extension we should return "" not "old"
    if( (last_dirsep_offset != wstring::npos) && (last_dirsep_offset > last_dot_offset) )
        return L"";

    return filename.substr( last_dot_offset + 1 );
}

You can use a built-in for this, strsplit:

> s = "TGAS_1121"
> s1 = unlist(strsplit(s, split='_', fixed=TRUE))[2]
> s1    
 [1] "1121"

strsplit returns both pieces of the string parsed on the split parameter as a list. That's probably not what you want, so wrap the call in unlist, then index that array so that only the second of the two elements in the vector are returned.

Finally, the fixed parameter should be set to TRUE to indicate that the split parameter is not a regular expression, but a literal matching character.

Check your windows task manager and make sure you kill all chrome processes before running the command.

start xxx.py

You can use this for some other file types.

Use java.util.Timer and Timer#schedule(TimerTask,delay,period) method will help you.

public class RemindTask extends TimerTask {
    public void run() {
      System.out.println(" Hello World!");
    }
    public static void main(String[] args){
       Timer timer = new Timer();
       timer.schedule(new RemindTask(), 3000,3000);
    }
  }

They should have the same time, the update is supposed to be atomic, meaning that whatever how long it takes to perform, the action is supposed to occurs as if all was done at the same time.

If you're experiencing a different behaviour, it's time to change for another DBMS.

You Create Custom ListView Which is non Scrollable

  public class NonScrollListView extends ListView {

            public NonScrollListView(Context context) {
                super(context);
            }
            public NonScrollListView(Context context, AttributeSet attrs) {
                super(context, attrs);
            }
            public NonScrollListView(Context context, AttributeSet attrs, int defStyle) {
                super(context, attrs, defStyle);
            }
            @Override
            public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
                    int heightMeasureSpec_custom = MeasureSpec.makeMeasureSpec(
                            Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
                    super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom);
                    ViewGroup.LayoutParams params = getLayoutParams();
                    params.height = getMeasuredHeight();    
            }
        }

In Your Layout Resources File

     <?xml version="1.0" encoding="utf-8"?>
        <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"

            android:fadingEdgeLength="0dp"
            android:fillViewport="true"
            android:overScrollMode="never"
            android:scrollbars="none" >

            <RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content" >

                <!-- com.Example Changed with your Package name -->

                <com.Example.NonScrollListView
                    android:id="@+id/lv_nonscroll_list"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content" >
                </com.Example.NonScrollListView>

                <RelativeLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_below="@+id/lv_nonscroll_list" >

                    <!-- Your another layout in scroll view -->

                </RelativeLayout>
            </RelativeLayout>

        </ScrollView>

In Java File Create a object of your customListview instead of ListView like : NonScrollListView non_scroll_list = (NonScrollListView) findViewById(R.id.lv_nonscroll_list);

keyboardType: TextInputType.number would open a num pad on focus, I would clear the text field when the user enters/past anything else.

keyboardType: TextInputType.number,
onChanged: (String newVal) {
    if(!isNumber(newVal)) {
        editingController.clear();
    }
}

// Function to validate the number
bool isNumber(String value) {
    if(value == null) {
        return true;
    }
    final n = num.tryParse(value);
    return n!= null;
}

I use this place all the time, thanks.

I was searching for how to undo a pull request and got here.

I was about to just git reset --hard to "a long time ago" and do a fast forward back to where I was before doing the pull request.

Besides looking here, I also asked my co-worker what he would do, and he had a typically good answer: using the example output in the first answer above:

git reset --hard 9271e6e

As with most things in Git, if you're doing it some way that's not easy, you're probably doing it wrong.

This is a method that I use to update AppSettings, works for both web and desktop applications. If you need to edit connectionStrings you can get that value from System.Configuration.ConnectionStringSettings config = configFile.ConnectionStrings.ConnectionStrings["YourConnectionStringName"]; and then set a new value with config.ConnectionString = "your connection string";. Note that if you have any comments in the connectionStrings section in Web.Config these will be removed.

private void UpdateAppSettings(string key, string value)
{
    System.Configuration.Configuration configFile = null;
    if (System.Web.HttpContext.Current != null)
    {
        configFile =
            System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
    }
    else
    {
        configFile =
            ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
    }
    var settings = configFile.AppSettings.Settings;
    if (settings[key] == null)
    {
        settings.Add(key, value);
    }
    else
    {
        settings[key].Value = value;
    }
    configFile.Save(ConfigurationSaveMode.Modified);
    ConfigurationManager.RefreshSection(configFile.AppSettings.SectionInformation.Name);
}

You could do the opposite of what you proposed.

location (/test)/ {
   set $folder $1;
}

location (/test_/something {
   set $folder $1;
}

You can use the indexOf method like this:

var index = array.indexOf(item);
if (index !== -1) {
  array.splice(index, 1);
}

Note: You'll need to shim it for IE8 and below

var array = [1,2,3,4]
var item = 3

var index = array.indexOf(item);
array.splice(index, 1);

console.log(array)

Just use:

if file_name.endswith(tuple(extensions)):

thanks to Jim Petkus that did gave me a wonderful answer . but i was trying to solve my own script not to changing it to another plugin . My main focus was not using an independent plugin and do what i wanted just by using the jquery core !

and guess what i did find the problem .

var title = $("em").attr("title");
$("div").text(title);

this is what i add to my script and the blew codes to my html part :

<td> <em title=\"$weight\">$weight</em></td>

and found each row $weight value

thanks again to Jim Petkus

This fiddle has both each and direct json. http://jsfiddle.net/streethawk707/a9ssja22/.

Below are the two ways of iterating over array. One is with direct json passing and another is naming the json array while passing to content holder.

Eg1: The below example is directly calling json key (data) inside small_data variable.

In html use the below code:

<div id="small-content-placeholder"></div>

The below can be placed in header or body of html:

<script id="small-template" type="text/x-handlebars-template">
    <table>
        <thead>
            <th>Username</th>
            <th>email</th>
        </thead>
        <tbody>
            {{#data}}
                <tr>
                    <td>{{username}}
                    </td>
                    <td>{{email}}</td>
                </tr>
            {{/data}}
        </tbody>
    </table>
</script>

The below one is on document ready:

var small_source   = $("#small-template").html();
var small_template = Handlebars.compile(small_source);

The below is the json:

var small_data = {
            data: [
                {username: "alan1", firstName: "Alan", lastName: "Johnson", email: "[email protected]" },
                {username: "alan2", firstName: "Alan", lastName: "Johnson", email: "[email protected]" }
            ]
        };

Finally attach the json to content holder:

$("#small-content-placeholder").html(small_template(small_data));

Eg2: Iteration using each.

Consider the below json.

var big_data = [
            {
                name: "users1",
                details: [
                    {username: "alan1", firstName: "Alan", lastName: "Johnson", email: "[email protected]" },
                    {username: "allison1", firstName: "Allison", lastName: "House", email: "[email protected]" },
                    {username: "ryan1", firstName: "Ryan", lastName: "Carson", email: "[email protected]" }
                  ]
            },
            {
                name: "users2",
                details: [
                    {username: "alan2", firstName: "Alan", lastName: "Johnson", email: "[email protected]" },
                    {username: "allison2", firstName: "Allison", lastName: "House", email: "[email protected]" },
                    {username: "ryan2", firstName: "Ryan", lastName: "Carson", email: "[email protected]" }
                  ]
            }
      ];

While passing the json to content holder just name it in this way:

$("#big-content-placeholder").html(big_template({big_data:big_data}));

And the template looks like :

<script id="big-template" type="text/x-handlebars-template">
    <table>
        <thead>
            <th>Username</th>
            <th>email</th>
        </thead>
        <tbody>
            {{#each big_data}}
                <tr>
                    <td>{{name}}
                            <ul>
                                {{#details}}
                                    <li>{{username}}</li>
                                    <li>{{email}}</li>
                                {{/details}}
                            </ul>
                    </td>
                    <td>{{email}}</td>
                </tr>
            {{/each}}
        </tbody>
    </table>
</script>

You can multiply numpy arrays by scalars and it just works.

>>> import numpy as np
>>> np.array([1, 2, 3]) * 2
array([2, 4, 6])
>>> np.array([[1, 2, 3], [4, 5, 6]]) * 2
array([[ 2,  4,  6],
       [ 8, 10, 12]])

This is also a very fast and efficient operation. With your example:

>>> a_1 = np.array([1.0, 2.0, 3.0])
>>> a_2 = np.array([[1., 2.], [3., 4.]])
>>> b = 2.0
>>> a_1 * b
array([2., 4., 6.])
>>> a_2 * b
array([[2., 4.],
       [6., 8.]])

This is a way to invoke one or more JavaScript methods from the code behind. By using Script Manager we can call the methods in sequence. Consider the below code for example.

ScriptManager.RegisterStartupScript(this, typeof(Page), "UpdateMsg", 
    "$(document).ready(function(){EnableControls();
    alert('Overrides successfully Updated.');
    DisableControls();});", 
true);

In this first method EnableControls() is invoked. Next the alert will be displayed. Next the DisableControls() method will be invoked.

If you're using Bash you could also use one of the following commands:

printf '%(%Y%m%d%H%M%S)T'       # prints the current time
printf '%(%Y%m%d%H%M%S)T' -1    # same as above
printf '%(%Y%m%d%H%M%S)T' -2    # prints the time the shell was invoked

You can use the Option -v varname to store the result in $varname instead of printing it to stdout:

printf -v varname '%(%Y%m%d%H%M%S)T'

While the date command will always be executed in a subshell (i.e. in a separate process) printf is a builtin command and will therefore be faster.

You can use node.js memoryUsage

const formatMemoryUsage = (data) => `${Math.round(data / 1024 / 1024 * 100) / 100} MB`

const memoryData = process.memoryUsage()

const memoryUsage = {
                rss: `${formatMemoryUsage(memoryData.rss)} -> Resident Set Size - total memory allocated for the process execution`,
                heapTotal: `${formatMemoryUsage(memoryData.heapTotal)} -> total size of the allocated heap`,
                heapUsed: `${formatMemoryUsage(memoryData.heapUsed)} -> actual memory used during the execution`,
                external: `${formatMemoryUsage(memoryData.external)} -> V8 external memory`,
}

console.log(memoryUsage)
/*
{
    "rss": "177.54 MB -> Resident Set Size - total memory allocated for the process execution",
    "heapTotal": "102.3 MB -> total size of the allocated heap",
    "heapUsed": "94.3 MB -> actual memory used during the execution",
    "external": "3.03 MB -> V8 external memory"
}
*/

Yes, there is a module fs-extra. There is a method .emptyDir() inside this module which does the job. Here is an example:

const fsExtra = require('fs-extra')

fsExtra.emptyDirSync(fileDir)

There is also an asynchronous version of this module too. Anyone can check out the link.

The error is caused by the "smart-quotes" (or whatever they're called). The lesson here is, "don't write your code in an 'editor' that converts quotes to smart-quotes".

names(newprice)[1]<-paste(“premium”)  # error
names(newprice)[1]<-paste("premium")  # works

Also, you don't need paste("premium") (the call to paste is redundant) and it's a good idea to put spaces around <- to avoid confusion (e.g. x <- -10; if(x<-3) "hi" else "bye"; x).

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

You may also need to specify the proxy server/port, in some environments the system settings for proxy are not enough for npm to work.

    npm config set proxy "http://your-proxy.com:80"

If you have more than one image and you need something generic that doesn't depend on a naming convention.

HTML

<img data-other-src="big-zebra.jpg" src="small-cat.jpg">
<img data-other-src="huge-elephant.jpg" src="white-mouse.jpg">
<img data-other-src="friendly-bear.jpg" src="penguin.jpg">

JavaScript

$('img').bind('mouseenter mouseleave', function() {
    $(this).attr({
        src: $(this).attr('data-other-src') 
        , 'data-other-src': $(this).attr('src') 
    })
});

In Swift 5:

label.textRect(forBounds: label.bounds, limitedToNumberOfLines: 1)

btw, the value of limitedToNumberOfLines depends on your label's text lines you want.

We can compare data from two tables of DB2 tables using the below simple query,

Step 1:- Select which all columns we need to compare from table (T1) of schema(S)

     SELECT T1.col1,T1.col3,T1.col5 from S.T1

Step 2:- Use 'Minus' keyword for comparing 2 tables.

Step 3:- Select which all columns we need to compare from table (T2) of schema(S)

     SELECT T2.col1,T2.col3,T2.col5 from S.T1

END result:

     SELECT T1.col1,T1.col3,T1.col5 from S.T1
     MINUS 
     SELECT T2.col1,T2.col3,T2.col5 from S.T1;

If the query returns no rows then the data is exactly the same.

You can use querySelectorAll:

    document.querySelectorAll('span[property=name]');

it sometimes occurs when we use a custom adapter in any activity of fragment . and we return null object i.e null view so the activity gets confused which view to load , so that is why this exception occurs

shows the position where to change the view

Self validated model

Your model should implement an interface IValidatableObject. Put your validation code in Validate method:

public class MyModel : IValidatableObject
{
    public string Title { get; set; }
    public string Description { get; set; }

    public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
    {
        if (Title == null)
            yield return new ValidationResult("*", new [] { nameof(Title) });

        if (Description == null)
            yield return new ValidationResult("*", new [] { nameof(Description) });
    }
}

Please notice: this is a server-side validation. It doesn't work on client-side. You validation will be performed only after form submission.

just in case someone comes to this question, I have the easier version.

public static MediaPlayer mp;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button b = (Button) findViewById(R.id.button);
        Button b2 = (Button) findViewById(R.id.button2);


        b.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                mp = MediaPlayer.create(MainActivity.this, R.raw.game);
                mp.start();
            }
        });

        b2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mp.stop();
               // mp.start();
            }
        });
    }

I usually use something like this:

>>> s = "string. With. Punctuation?" # Sample string
>>> import string
>>> for c in string.punctuation:
...     s= s.replace(c,"")
...
>>> s
'string With Punctuation'

Use print_r:

$myText = print_r($myVar,true);

You can also use it like:

$myText = print_r($myVar,true)."foo bar";

This will set $myText to a string, like:

array (
  0 => '11',
)foo bar

Use var_export to get a little bit more info (with types of variable,...):

$myText = var_export($myVar,true);

In my case, the patch was generated perfectly fine by IDEA, however, I edited the patch and saved it which changed CRLF to LF and then the patch stopped working. Curiously, converting it back to CRLF did not work. I noticed in VI editor, that even after setting to DOS format, the '^M' were not added to the end of lines. This forced me to only make changes in VI, so that the EOLs were preserved.

This may apply to you, if you make changes in a non-Windows environment to a patch covering changes between two versions both coming from Windows environment. You want to be careful how you edit such files.

BTW ignore-whitespace did not help.

One of reasons why you will get this Notice: Array to string conversion in… is that you are combining group of arrays. Example, sorting out several first and last names.

To echo elements of array properly, you can use the function, implode(separator, array) Example:

implode(' ', $var)

result:

first name[1], last name[1]
first name[2], last name[2]

More examples from W3C.

Postgres variables are created through the \set command, for example ...

\set myvariable value

... and can then be substituted, for example, as ...

SELECT * FROM :myvariable.table1;

... or ...

SELECT * FROM table1 WHERE :myvariable IS NULL;

edit: As of psql 9.1, variables can be expanded in quotes as in:

\set myvariable value 

SELECT * FROM table1 WHERE column1 = :'myvariable';

In older versions of the psql client:

... If you want to use the variable as the value in a conditional string query, such as ...

SELECT * FROM table1 WHERE column1 = ':myvariable';

... then you need to include the quotes in the variable itself as the above will not work. Instead define your variable as such ...

\set myvariable 'value'

However, if, like me, you ran into a situation in which you wanted to make a string from an existing variable, I found the trick to be this ...

\set quoted_myvariable '\'' :myvariable '\''

Now you have both a quoted and unquoted variable of the same string! And you can do something like this ....

INSERT INTO :myvariable.table1 SELECT * FROM table2 WHERE column1 = :quoted_myvariable;

You can specify the whole day by doing a range, like so:

WHERE bk_date >= TO_DATE('2012-03-18', 'YYYY-MM-DD')
AND bk_date <  TO_DATE('2012-03-19', 'YYYY-MM-DD')

More simply you can use TRUNC:

WHERE TRUNC(bk_date) = TO_DATE('2012-03-18', 'YYYY-MM-DD')

TRUNC without parameter removes hours, minutes and seconds from a DATE.

You can use this code for connect and request using http and json

try {
         
        URL url = new URL("https://www.googleapis.com/youtube/v3/playlistItems?part=snippet"
                + "&key="+key
                + "&access_token=" + access_token);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setDoOutput(true);
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Content-Type", "application/json");
 
        String input = "{ \"snippet\": {\"playlistId\": \"WL\",\"resourceId\": {\"videoId\": \""+videoId+"\",\"kind\": \"youtube#video\"},\"position\": 0}}";
 
        OutputStream os = conn.getOutputStream();
        os.write(input.getBytes());
        os.flush();
 
        if (conn.getResponseCode() != HttpURLConnection.HTTP_CREATED) {
            throw new RuntimeException("Failed : HTTP error code : "
                + conn.getResponseCode());
        }
 
        BufferedReader br = new BufferedReader(new InputStreamReader(
                (conn.getInputStream())));
 
        String output;
        System.out.println("Output from Server .... \n");
        while ((output = br.readLine()) != null) {
            System.out.println(output);
        }
 
        conn.disconnect();
 
      } catch (MalformedURLException e) {
 
        e.printStackTrace();
 
      } catch (IOException e) {
 
        e.printStackTrace();
 
     }

JDO is dead

JDO is not dead actually so please check your facts. JDO 2.2 was released in Oct 2008 JDO 2.3 is under development.

This is developed openly, under Apache. More releases than JPA has had, and its ORM specification is still in advance of even the JPA2 proposed features

table-layout: fixed will get force the cells to fit the table (and not the other way around), e.g.:

<table style="border: 1px solid black; width: 100%; word-wrap:break-word;
              table-layout: fixed;">
  <tr>
    <td>
        aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
        bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
    </td>
  </tr>
</table>

The problem is, that openssl -verify does not do the job.

As Priyadi mentioned, openssl -verify stops at the first self signed certificate, hence you do not really verify the chain, as often the intermediate cert is self-signed.

I assume that you want to be 101% sure, that the certificate files are correct before you try to install them in the productive web service. This recipe here performs exactly this pre-flight-check.

Please note that the answer of Peter is correct, however the output of openssl -verify is no clue that everything really works afterwards. Yes, it might find some problems, but quite not all.

Here is a script which does the job to verify a certificate chain before you install it into Apache. Perhaps this can be enhanced with some of the more mystic OpenSSL magic, but I am no OpenSSL guru and following works:

There is a GitHub Gist of this which might have some updates

Prerequisites of this script:

• You have the trusted CA root data in /etc/ssl/certs as usual for example on Ubuntu
• Create a directory DIR where you store 3 files:
  • DIR/certificate.crt which contains the certificate
  • DIR/certificate.key which contains the secret key for your webservice (without passphrase)
  • DIR/certificate.bundle which contains the CA-Bundle. On how to prepare the bundle, see below.
• Now run the script: ./check DIR/certificate (this assumes that the script is named check in the current directory)
• There is a very unlikely case that the script outputs CA-Bundle is not needed. This means, that you (read: /etc/ssl/certs/) already trusts the signing certificate. But this is highly unlikely in the WWW.
• For this test port 4433 must be unused on your workstation. And better only run this in a secure environment, as it opens port 4433 shortly to the public, which might see foreign connects in a hostile environment.

How to create the certificate.bundle file?

In the WWW the trust chain usually looks like this:

• trusted certificate from /etc/ssl/certs
• unknown intermediate certificate(s), possibly cross signed by another CA
• your certificate (certificate.crt)

Now, the evaluation takes place from bottom to top, this means, first, your certificate is read, then the unknown intermediate certificate is needed, then perhaps the cross-signing-certificate and then /etc/ssl/certs is consulted to find the proper trusted certificate.

The ca-bundle must be made up in excactly the right processing order, this means, the first needed certificate (the intermediate certificate which signs your certificate) comes first in the bundle. Then the cross-signing-cert is needed.

Usually your CA (the authority who signed your certificate) will provide such a proper ca-bundle-file already. If not, you need to pick all the needed intermediate certificates and cat them together into a single file (on Unix). On Windows you can just open a text editor (like notepad.exe) and paste the certificates into the file, the first needed on top and following the others.

There is another thing. The files need to be in PEM format. Some CAs issue DER (a binary) format. PEM is easy to spot: It is ASCII readable. For mor on how to convert something into PEM, see How to convert .crt to .pem and follow the yellow brick road.

Example:

You have:

• intermediate2.crt the intermediate cert which signed your certificate.crt
• intermediate1.crt another intermediate cert, which singed intermediate2.crt
• crossigned.crt which is a cross signing certificate from another CA, which signed intermediate1.crt
• crossintermediate.crt which is another intermediate from the other CA which signed crossigned.crt (you probably will never ever see such a thing)

Then the proper cat would look like this:

cat intermediate2.crt intermediate1.crt crossigned.crt crossintermediate.crt > certificate.bundle

And how can you find out which files are needed or not and in which sequence?

Well, experiment, until the check tells you everything is OK. It is like a computer puzzle game to solve the riddle. Every. Single. Time. Even for pros. But you will get better each time you need to do this. So you are definitively not alone with all that pain. It's SSL, ya' know? SSL is probably one of the worst designs I ever saw in over 30 years of professional system administration. Ever wondered why crypto has not become mainstream in the last 30 years? That's why. 'nuff said.

The GUI way in Android Studio

• Have the Android app part of the React Native app open in Android Studio (this just means opening the android folder of your react-native project with Android Studio)
• Go to the "Build" tab at the top
• Go down to "Build Bundle(s) / APK(s)"
• Then select "Build APK(s)"
• This will walk you through a process of locating your keys to sign the APK or creating your keys if you don't have them already which is all very straightforward. If you're just practicing, you can generate these keys and save them to your desktop.
• Once that process is complete and if the build was successful, there will be a popup down below in Android Studio. Click the link within it that says "locate" (the APK)
• That will take you to the apk file, move that over to your android device. Then navigate to that file on the Android device and install it.

For Java SE 5: According to Garbage Collector Ergonomics [Oracle]:

initial heap size:

Larger of 1/64th of the machine's physical memory on the machine or some reasonable minimum. Before J2SE 5.0, the default initial heap size was a reasonable minimum, which varies by platform. You can override this default using the -Xms command-line option.

maximum heap size:

Smaller of 1/4th of the physical memory or 1GB. Before J2SE 5.0, the default maximum heap size was 64MB. You can override this default using the -Xmx command-line option.

UPDATE:

As pointed out by Tom Anderson in his comment, the above is for server-class machines. From Ergonomics in the 5.0 JavaTM Virtual Machine:

In the J2SE platform version 5.0 a class of machine referred to as a server-class machine has been defined as a machine with

• 2 or more physical processors
• 2 or more Gbytes of physical memory

with the exception of 32 bit platforms running a version of the Windows operating system. On all other platforms the default values are the same as the default values for version 1.4.2.

In the J2SE platform version 1.4.2 by default the following selections were made

• initial heap size of 4 Mbyte
• maximum heap size of 64 Mbyte

int[] a = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

man page of strcat says that arg1 and arg2 are appended to arg1.. and returns the pointer of s1. If you dont want disturb str1,str2 then you have write your own function.

char * my_strcat(const char * str1, const char * str2)
{
   char * ret = malloc(strlen(str1)+strlen(str2));

   if(ret!=NULL)
   {
     sprintf(ret, "%s%s", str1, str2);
     return ret;
   }
   return NULL;    
}

Hope this solves your purpose

You don't "remove the character 'u' from a list", you encode Unicode strings. In fact the strings you have are perfectly fine for most uses; you will just need to encode them appropriately before outputting them.

Your pip is a soft link to the same executable file path with pip3. you can use the commands below to check where your pip and pip3 real paths are:

$ ls -l `which pip`
$ ls -l `which pip3`

You may also use the commands below to know more details:

$ pip show pip
$ pip3 show pip

When we install different versions of python, we may create such soft links to

• set default pip to some version.
• make different links for different versions.

It is the same situation with python, python2, python3

file.readlines() takes in an optional size argument which approximates the number of lines read in the lines returned.

bigfile = open('bigfilename','r')
tmp_lines = bigfile.readlines(BUF_SIZE)
while tmp_lines:
    process([line for line in tmp_lines])
    tmp_lines = bigfile.readlines(BUF_SIZE)

Your submodule history is safely preserved in the submodule git anyway.

So, why not just delete the submodule and add it again?

Otherwise, did you try manually editing the HEAD or the refs/master/head within the submodule .git

The best way to accomplish that is to use POST which is a method of Hypertext Transfer Protocol https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods

index.php

<html>
<body>

<form action="site2.php" method="post">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit">
</form>

</body>
</html> 

site2.php

 <html>
 <body>

 Hello <?php echo $_POST["name"]; ?>!<br>
 Your mail is <?php echo $_POST["mail"]; ?>.

 </body>
 </html> 

output

Hello "name" !

Your email is "[email protected]" .

Wrap the description in a textarea element.

The ?type=daily argument (ending up in the $_GET array) is only valid for web-accessed pages.

You'll need to call it like php myfile.php daily and retrieve that argument from the $argv array (which would be $argv[1], since $argv[0] would be myfile.php).

If the page is used as a webpage as well, there are two options you could consider. Either accessing it with a shell script and Wget, and call that from cron:

#!/bin/sh
wget http://location.to/myfile.php?type=daily

Or check in the PHP file whether it's called from the command line or not:

if (defined('STDIN')) {
  $type = $argv[1];
} else {
  $type = $_GET['type'];
}

(Note: You'll probably need/want to check if $argv actually contains enough variables and such)

This is a very old question, but I found a really simple way to do this:

authorsList = authorsList.Except(authors).ToList();

Note that since the return variable authorsList is a List<T>, the IEnumerable<T> returned by Except() must be converted to a List<T>.

A lot of people have mention that "objects cannot be sorted", but after that they are giving you a solution which works. Paradox, isn't it?

No one mention why those solutions are working. They are, because in most of the browser's implementations values in objects are stored in the order in which they were added. That's why if you create new object from sorted list of keys it's returning an expected result.

And I think that we could add one more solution – ES5 functional way:

function sortObject(obj) {
    return Object.keys(obj).sort().reduce(function (result, key) {
        result[key] = obj[key];
        return result;
    }, {});
}

ES2015 version of above (formatted to "one-liner"):

const sortObject = o => Object.keys(o).sort().reduce((r, k) => (r[k] = o[k], r), {})

Short explanation of above examples (as asked in comments):

Object.keys is giving us a list of keys in provided object (obj or o), then we're sorting those using default sorting algorithm, next .reduce is used to convert that array back into an object, but this time with all of the keys sorted.

For the same issue on Windows7

You will see an error like this if your environment variables/ system variables are incorrectly set:

Fatal Python error: Py_Initialize: unable to load the file system codec
ImportError: No module named 'encodings'

Current thread 0x00001db4 (most recent call first):

Fixing this is really simple:

1. When you download Python3.x version, and run the .exe file, it gives you an option to customize where in your system you want to install Python. For example, I chose this location: C:\Program Files\Python36

2. Then open system properties and go to "Advanced" tab (Or you can simply do this: Go to Start > Search for "environment variables" > Click on "Edit the system environment variables".) Under the "Advanced" tab, look for "Environment Variables" and click it. Another window with name "Environment Variables" will pop up.

3. Now make sure your user variables have the correct Python path listed in "Path Variable". In my example here, you should see C:\Program Files\Python36. If you do not find it there, add it, by selecting Path Variable field and clicking Edit.

4. Last step is to double-check PYTHONHOME and PYTHONPATH fields under System Variables in the same window. You should see the same path as described above. If not add it there too.

Then click OK and go back to CMD terminal, and try checking for python. The issue should now be resolved. It worked for me.

For Android Studio add the following to your top-level build.gradle file within the allprojects block

tasks.withType(JavaCompile) {
    options.compilerArgs << "-Xlint:unchecked" << "-Xlint:deprecation" 
}

You can't. It's a browser feature there to prevent sites from showing hundreds of alerts to prevent you from leaving.

You can, however, look into modal popups like jQuery UI Dialog. These are javascript alert boxes that show a custom dialog. They don't use the default alert() function and therefore, bypass the issue you're running into completely.

I've found that an apps that has a lot of message boxes and confirms has a much better user experience if you use custom dialogs instead of the default alerts and confirms.

Here is code for getting value return from Store procedure

Stored procedure:

alter proc [dbo].[UserlogincheckMVC]    
@username nvarchar(max),    
@password nvarchar(max)
as    
begin    
    if exists(select Username from Adminlogin where Username =@username and Password=@password)    
        begin        
            return 1  
        end    
    else    
        begin     
            return 0  
        end    
end 

Code:

var parameters = new DynamicParameters();
string pass = EncrytDecry.Encrypt(objUL.Password);
conx.Open();
parameters.Add("@username", objUL.Username);
parameters.Add("@password", pass);
parameters.Add("@RESULT", dbType: DbType.Int32, direction: ParameterDirection.ReturnValue);
var RS = conx.Execute("UserlogincheckMVC", parameters, null, null, commandType: CommandType.StoredProcedure);
int result = parameters.Get<int>("@RESULT");

if you have CRUD (index) and you need set default sorting your controller for GridView, or ListView, or more... Example

public function actionIndex()
{
    $searchModel = new NewsSearch();
    $dataProvider = $searchModel->search(Yii::$app->request->queryParams);
    // set default sorting
    $dataProvider->sort->defaultOrder = ['id' => SORT_DESC];

    return $this->render('index', [
        'searchModel' => $searchModel,
        'dataProvider' => $dataProvider,
    ]);
}

you need add

$dataProvider->sort->defaultOrder = ['id' => SORT_DESC];

Here is a more literal answer (parent window as opposed to opener) to the original question that can be used within an iframe, assuming the domain name in the iframe matches that of the parent window:

window.parent.$("#serverMsg")

What about a shorter and more reliable one?

for i in **/*.pdf; do rm "$i"; done

Here is a small snippet to demonstrate the date modifications:

$date = date("Y-m-d");
//increment 2 days
$mod_date = strtotime($date."+ 2 days");
echo date("Y-m-d",$mod_date) . "\n";

//decrement 2 days
$mod_date = strtotime($date."- 2 days");
echo date("Y-m-d",$mod_date) . "\n";

//increment 1 month
$mod_date = strtotime($date."+ 1 months");
echo date("Y-m-d",$mod_date) . "\n";

//increment 1 year
$mod_date = strtotime($date."+ 1 years");
echo date("Y-m-d",$mod_date) . "\n";

This is my solution for something similar to this problem:

System.Windows.Forms.WebBrowser www;

void VerificarWebSites()
{
    www = new System.Windows.Forms.WebBrowser();
    www.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(www_DocumentCompleted_login);
    www.Navigate(new Uri("http://www.meusite.com.br"));
}

void www_DocumentCompleted_login(object sender, WebBrowserDocumentCompletedEventArgs e)
{            
    www.DocumentCompleted -= new WebBrowserDocumentCompletedEventHandler(www_DocumentCompleted_login);
    www.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(www_DocumentCompleted_logado);

    www.Document.Forms[0].All["tbx_login"].SetAttribute("value", "Gostoso");
    www.Document.Forms[0].All["tbx_senha"].SetAttribute("value", "abcdef");
    www.Document.GetElementById("btn_login").Focus();
    www.Document.GetElementById("btn_login").InvokeMember("click");
}

void www_DocumentCompleted_logado(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    System.IO.StreamWriter sw = new StreamWriter("c:\\saida_teste.txt");
    sw.Write(www.DocumentText);
    sw.Close();
    MessageBox.Show(e.Url.AbsolutePath);
}

I ran into a similar problem because my master was set to " # of executor (The maximum number of concurrent builds that Jenkins may perform on this agent).

Go to Jenkins --> Manage Jenkins --> Manage Nodes, and click on the configure button of your master node (increase the number of executor to run mutiple jobs at a time).

You should supply the SqlParameter instances in the following way:

context.Database.SqlQuery<myEntityType>(
    "mySpName @param1, @param2, @param3",
    new SqlParameter("param1", param1),
    new SqlParameter("param2", param2),
    new SqlParameter("param3", param3)
);

I want to say something about the "G" status,

G: Changes on the repo were automatically merged into the working copy

I think the above definition is not cleary, it can generate a little confusion, because all files are automatically merged in to working copy, the correct one should be:

U = item (U)pdated to repository version

G = item’s local changes mer(G)ed with repository

C = item’s local changes (C)onflicted with repository

D = item (D)eleted from working copy

A = item (A)dded to working copy

The permgen space is the area of heap that holds all the reflective data of the virtual machine itself, such as class and method objects.

I know the accepted answer is great but for anyone who is looking for a hover like feel you can use setTimeout on mouseover and save the handle in a map (of let's say list ids to setTimeout Handle). On mouseover clear the handle from setTimeout and delete it from the map

onMouseOver={() => this.onMouseOver(someId)}
onMouseOut={() => this.onMouseOut(someId)

And implement the map as follows:

onMouseOver(listId: string) {
  this.setState({
    ... // whatever
  });

  const handle = setTimeout(() => {
    scrollPreviewToComponentId(listId);
  }, 1000); // Replace 1000ms with any time you feel is good enough for your hover action
  this.hoverHandleMap[listId] = handle;
}

onMouseOut(listId: string) {
  this.setState({
    ... // whatever
  });

  const handle = this.hoverHandleMap[listId];
  clearTimeout(handle);
  delete this.hoverHandleMap[listId];
}

And the map is like so,

hoverHandleMap: { [listId: string]: NodeJS.Timeout } = {};

I prefer onMouseOver and onMouseOut because it also applies to all the children in the HTMLElement. If this is not required you may use onMouseEnter and onMouseLeave respectively.

This worked in my case: Use %USERPROFILE% instead of giving path .keystore file stored in this path automatically C:Users/user name/.android:

keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

.pyc contain the compiled bytecode of Python source files. The Python interpreter loads .pyc files before .py files, so if they're present, it can save some time by not having to re-compile the Python source code. You can get rid of them if you want, but they don't cause problems, they're not big, and they may save some time when running programs.

Answer by @Calvin Froedge is the shortest answer but have an issue also mentioned by @kizu. Due to inconsistent width of the div the div will flick on hover. To solve this issue add minus margin to the right on hover

#div { 
     overflow:hidden;
     height:whatever px; 
}
#div:hover { 
     overflow-y:scroll; 
     margin-right: -15px; // adjust according to scrollbar width  
}

"cell one","cell "" two","cell "" ,three"

Save this to csv file and see the results, so double quote is used to escape itself

Important Note

"cell one","cell "" two", "cell "" ,three"

will give you a different result because there is a space after the comma, and that will be treated as "

You can use a simple HTML element <embed src="file.txt"> it loads the external resource and displays it on the screen no js needed

See how the Code is working here:

After calling the Async task, the async task runs in the background. that is desirable. Now, this Async task has a progress dialog which is attached to the Activity, if you ask how to see the code:

pDialog = new ProgressDialog(CLASS.this);

You are passing the Class.this as context to the argument. So the Progress dialog is still attached to the activity.

Now consider the scenario: If we try to finish the activity using the finish() method, while the async task is in progress, is the point where you are trying to access the Resource attached to the activity ie the progress bar when the activity is no more there.

Hence you get:

java.lang.IllegalArgumentException: View not attached to the window manager

Solution to this:

1) Make sure that the Dialog box is dismissed or canceled before the activity finishes.

2) Finish the activity, only after the dialog box is dismissed, that is the async task is over.

Pelo Hyper-V:

    Process.GetCurrentProcess().ProcessName); 

This Solution works when nothing else works:

I spent more than a week to convert the whole project and came to a solution below:

First, de-integrate the cocopods dependency from the project and then start converting the project to the latest swift version.

Go to Project Directory in the Terminal and Type:

pod deintegrate

This will de-integrate cocopods from the project and No traces of CocoaPods will be left in the project. But at the same time, it won't delete the xcworkspace and podfiles. It's ok if they are present.

Now you have to open xcodeproj(not xcworkspace) and you will get lots of errors because you have called cocoapods dependency methods in your main projects.

So to remove those errors you have two options:

1. Comment down all the code you have used from cocoapods library.
2. Create a wrapper class which has dummy methods similar to cocopods library, and then call it.

Once all the errors get removed you can convert the code to the latest swift version.

Sometimes if you are getting weird errors then try cleaning derived data and try again.

static void Main()
    {
        string input = "OneTwoThree";

            //Get last 5 characters
        string sub = input.Substring(6);
        Console.WriteLine("Substring: {0}", sub); // Output Three. 
    }

• Substring(0, 3) - Returns substring of first 3 chars. //One

• Substring(3, 3) - Returns substring of second 3 chars. //Two

• Substring(6) - Returns substring of all chars after first 6. //Three

You can try nvtop, which is similar to the widely-used htop tool but for NVIDIA GPUs. Here is a screenshot of nvtop of it in action.

I find:

ps -ax | grep mongo

To be a lot more consistent. The value returned can be used to detect how many instances of mongod there are running

Read file contents into a variable:

for /f "delims=" %%x in (version.txt) do set Build=%%x

or

set /p Build=<version.txt

Both will act the same with only a single line in the file, for more lines the for variant will put the last line into the variable, while set /p will use the first.

Using the variable – just like any other environment variable – it is one, after all:

%Build%

So to check for existence:

if exist \\fileserver\myapp\releasedocs\%Build%.doc ...

Although it may well be that no UNC paths are allowed there. Can't test this right now but keep this in mind.

You can use:ls -lh, then you will get a list of file information

PHP

Here is the PHP's version (input values are: $latitude and $longitude):

$latitude_pattern  = '/\A[+-]?(?:90(?:\.0{1,18})?|\d(?(?<=9)|\d?)\.\d{1,18})\z/x';
$longitude_pattern = '/\A[+-]?(?:180(?:\.0{1,18})?|(?:1[0-7]\d|\d{1,2})\.\d{1,18})\z/x';
if (preg_match($latitude_pattern, $latitude) && preg_match($longitude_pattern, $longitude)) {
  // Valid coordinates.
}

when: myvar | default('', true) | trim != ''

I use | trim != '' to check if a variable has an empty value or not. I also always add the | default(..., true) check to catch when myvar is undefined too.

the code can be used to sort string in alphabetical order without using any inbuilt function of python

k = input("Enter any string again ")

li = []
x = len(k)
for i in range (0,x):
    li.append(k[i])

print("List is : ",li)


for i in range(0,x):
    for j in range(0,x):
        if li[i]<li[j]:
            temp = li[i]
            li[i]=li[j]
            li[j]=temp
j=""

for i in range(0,x):
    j = j+li[i]

print("After sorting String is : ",j)

you must use import android.support.v7.app.ActionBarDrawerToggle;

and use the constructor

public CustomActionBarDrawerToggle(Activity mActivity,DrawerLayout mDrawerLayout)
{
    super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);
}

and if the drawer toggle button becomes dark then you must use the supportActionBar provided in the support library.

You can implement supportActionbar from this link: http://developer.android.com/training/basics/actionbar/setting-up.html

function palindromCheck(str) {
    var palinArr, i,
        palindrom = [],

    palinArr = str.split(/[\s!.?,;:'"-()]/ig);

    for (i = 0; i < palinArr.length; i++) {
        if (palinArr[i].toLowerCase() === palinArr[i].split('').reverse().join('').toLowerCase() &&
            palinArr[i] !== '') {
            palindrom.push(palinArr[i]);
        }
    }
        return palindrom.join(', ');
}
console.log(palindromCheck('There is a man, his name! was Bob.')); //a, Bob

Finds and upper to lower case. Split string into array, I don't know why a few white spaces remain, but I wanted to catch and single letters.

In my case, I had copied some code from another project that was using Automapper - took me ages to work that one out. Just had to add automapper nuget package to project.

In swift 3 and above

=== (or !==)

• Checks if the values are identical (both point to the same memory address).
• Comparing reference types.
• Like == in Obj-C (pointer equality).

== (or !=)

• Checks if the values are the same.
• Comparing value types.
• Like the default isEqual: in Obj-C behavior.

Here I compare three instances (class is a reference type)

class Person {}

let person = Person()
let person2 = person
let person3 = Person()

person === person2 // true
person === person3 // false

I had 20.8 GB in the C:\Users\ggo\AppData\Local\Android\Sdk\system-images folder (6 android images: - android-10 - android-15 - android-21 - android-23 - android-25 - android-26 ).

I have compressed the C:\Users\ggo\AppData\Local\Android\Sdk\system-images folder.

Now it takes only 4.65 GB.

I did not encountered any problem up to now...

Compression seems to vary from 2/3 to 6, sometimes much more:

Actually quite easy to roll your own tester, by abusing Java's method overload ability. Though I'm still curious if there is an official method in the sdk.

Example:

class Typetester {
    void printType(byte x) {
        System.out.println(x + " is an byte");
    }
    void printType(int x) {
        System.out.println(x + " is an int");
    }
    void printType(float x) {
        System.out.println(x + " is an float");
    }
    void printType(double x) {
        System.out.println(x + " is an double");
    }
    void printType(char x) {
        System.out.println(x + " is an char");
    }
}

then:

Typetester t = new Typetester();
t.printType( yourVariable );

I was struggling with the above solutions when I wanted to automate my ordering process for n columns, whose column names could be different each time. I found a super helpful function from the psych package to do this in a straightforward manner:

dfOrder(myDf, columnIndices)

where columnIndices are indices of one or more columns, in the order in which you want to sort them. More information here:

dfOrder function from 'psych' package

To really get this clear, here's my for-beginners answer: You inputed the arguments in the wrong order.
A keyword argument has this style:

nullable=True, unique=False

A fixed parameter should be defined: True, False, etc. A non-keyword argument is different:

name="Ricardo", fruit="chontaduro" 

This syntax error asks you to first put name="Ricardo" and all of its kind (non-keyword) before those like nullable=True.

• Pro base64: the encoded representation you handle is a pretty safe string. It contains neither control chars nor quotes. The latter point helps against SQL injection attempts. I wouldn't expect any problem to just add the value to a "hand coded" SQL query string.

• Pro BLOB: the database manager software knows what type of data it has to expect. It can optimize for that. If you'd store base64 in a TEXT field it might try to build some index or other data structure for it, which would be really nice and useful for "real" text data but pointless and a waste of time and space for image data. And it is the smaller, as in number of bytes, representation.

Create an Event object and pass it to the dispatchEvent method of the element:

var element = document.getElementById('just_an_example');
var event = new Event('change');
element.dispatchEvent(event);

This will trigger event listeners regardless of whether they were registered by calling the addEventListener method or by setting the onchange property of the element.

If you want the event to bubble, you need to pass a second argument to the Event constructor:

var event = new Event('change', { bubbles: true });

Information about browser compability:

• dispatchEvent()
• Event()

In your case I would consider using Set and not List, to ensure you have unique values only. unless you need sometimes to include duplicates.

In this case, you don't need to add any wrapper functions around lists.

A slight change to Thangamani Palanisamy answer, which allows the Binary reader to be disposed and corrects the input length issue in his comments.

string result = string.Empty;

using (BinaryReader b = new BinaryReader(file.InputStream))
{
  byte[] binData = b.ReadBytes(file.ContentLength);
  result = System.Text.Encoding.UTF8.GetString(binData);
}

PrjForm was set to ".Net Framework 4 Client Profile" I changed it to ".Net Framework 4", and now I have a successful build.

This worked for me too. Thanks a lot. I was trying an RDF example for dotNet where in I downloaded kit from dotnetrdf.

NET4 Client Profile: Always target NET4 Client Profile for all your client desktop applications (including Windows Forms and WPF apps).

NET4 Full framework: Target NET4 Full only if the features or assemblies that your app need are not included in the Client Profile. This includes: If you are building Server apps, Such as:

• ASP.Net apps
• Server-side ASMX based web services

If you use legacy client scenarios, Such as: o Use System.Data.OracleClient.dll which is deprecated in NET4 and not included in the Client Profile.

• Use legacy Windows Workflow Foundation 3.0 or 3.5 (WF3.0 , WF3.5)

If you targeting developer scenarios and need tool such as MSBuild or need access to design assemblies such as System.Design.dll

You can emit custom native javascript event from a directive. Create a directive that dispatches an event from the node, using node.dispatchEvent

let handleOutsideClick;
Vue.directive('out-click', {
    bind (el, binding, vnode) {

        handleOutsideClick = (e) => {
            e.stopPropagation()
            const handler = binding.value

            if (el.contains(e.target)) {
                el.dispatchEvent(new Event('out-click')) <-- HERE
            }
        }

        document.addEventListener('click', handleOutsideClick)
        document.addEventListener('touchstart', handleOutsideClick)
    },
    unbind () {
        document.removeEventListener('click', handleOutsideClick)
        document.removeEventListener('touchstart', handleOutsideClick)
    }
})

Which can be used like this

h3( v-out-click @click="$emit('show')" @out-click="$emit('hide')" )

if you already know your folder is: E:\ftproot\sales then you do not need to use Server.MapPath, this last one is needed if you only have a relative virtual path like ~/folder/folder1 and you want to know the real path in the disk...

finish() method is used to finish the activity and remove it from back stack. You can call it in any method in activity. But make sure you close all the Database connections, all reference variables null to prevent any memory leaks.

Shallow copy with copy.copy()

#!/usr/bin/env python3

import copy

class C():
    def __init__(self):
        self.x = [1]
        self.y = [2]

# It copies.
c = C()
d = copy.copy(c)
d.x = [3]
assert c.x == [1]
assert d.x == [3]

# It's shallow.
c = C()
d = copy.copy(c)
d.x[0] = 3
assert c.x == [3]
assert d.x == [3]

Deep copy with copy.deepcopy()

#!/usr/bin/env python3
import copy
class C():
    def __init__(self):
        self.x = [1]
        self.y = [2]
c = C()
d = copy.deepcopy(c)
d.x[0] = 3
assert c.x == [1]
assert d.x == [3]

The common practice nowadays is to generate a content hash code as part of the file name to force the browser especially IE to reload the javascript files or css files.

For example,

vendor.a7561fb0e9a071baadb9.js
main.b746e3eb72875af2caa9.js

It is generally the job for the build tools such as webpack. Here is more details if anyone wants to try out if you are using webpack.

Add one line of code after setContentView() in onCreate()

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_flag);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}

For security reasons, your script cannot close a window/tab that it did not open.

The solution is to present the age prompt at an earlier point in the navigation history. Then, you can choose to allow them to enter your site or not based on their input.

Instead of closing the page that presents the prompt, you can simply say, "Sorry", or perhaps redirect the user to their homepage.

From Dockerfile reference:

• The ARG instruction defines a variable that users can pass at build-time to the builder with the docker build command using the --build-arg <varname>=<value> flag.

• The ENV instruction sets the environment variable <key> to the value <value>.
  The environment variables set using ENV will persist when a container is run from the resulting image.

So if you need build-time customization, ARG is your best choice.
If you need run-time customization (to run the same image with different settings), ENV is well-suited.

If I want to add let's say 20 (a random number) of extensions or any other feature that can be enable|disable

Given the number of combinations involved, using ENV to set those features at runtime is best here.

But you can combine both by:

• building an image with a specific ARG
• using that ARG as an ENV

That is, with a Dockerfile including:

ARG var
ENV var=${var}

You can then either build an image with a specific var value at build-time (docker build --build-arg var=xxx), or run a container with a specific runtime value (docker run -e var=yyy)

Just adding a bit of extra information here in case someone has the same issue as me.

I use namespaces in my code and I had a class with a function that throws an Exception.

However my try/catch code in another class file was completely ignored and the normal PHP error for an uncatched exception was thrown.

Turned out I forgot to add "use \Exception;" at the top, adding that solved the error.

Use NSAssert and friends. I use nil as valid object all the time ... especially sending messages to nil is perfectly valid in Obj-C. However if I really want to make sure about the state of a variable, I use NSAssert and NSParameterAssert, which helps to track down problems easily.

Use hex(id)[2:] and int(urlpart, 16). There are other options. base32 encoding your id could work as well, but I don't know that there's any library that does base32 encoding built into Python.

Apparently a base32 encoder was introduced in Python 2.4 with the base64 module. You might try using b32encode and b32decode. You should give True for both the casefold and map01 options to b32decode in case people write down your shortened URLs.

Actually, I take that back. I still think base32 encoding is a good idea, but that module is not useful for the case of URL shortening. You could look at the implementation in the module and make your own for this specific case. :-)

Anytime you have a question about a particular function in PHP, the easiest way to get quick answers is by visiting php.net, which has great documentation on all of the language's capabilities.

Looking up a function is easy, just visit http://php.net/<function name> and it will forward you to the appropriate place. For the date function, we'll visit http://php.net/date.

We immediately learn a couple things about this function by examining its signature:

string date ( string $format [, int $timestamp = time() ] )

First, it returns a string. That's what the first string in the above code means. Secondly, the first parameter is expected to be a string containing the format. There is an optional second parameter for passing in your own timestamp (to construct strings from some time other than now).

date("d-m-Y") // produces something like 03-12-2012

In this code, d represents the day of the month (with a leading 0 is necessary). m represents the month, again with a leading zero if necessary. And Y represents the full 4-digit year. All of these are documented in the aforementioned link.

To satisfy your request of getting the hours, minutes, and seconds, we need to give a quick look at the documentation to see which characters represents those particular units of time. When we do that, we find the following:

h   12-hour format of an hour with leading zeros    01 through 12
i   Minutes with leading zeros                      00 to 59
s   Seconds, with leading zeros                     00 through 59

With this in mind, we can no create a new format string:

date("d-m-Y h:i:s"); // produces something like 03-12-2012 03:29:13

Hope this is helpful, and I hope you find the documentation has benefiting to your development as I have to mine.

In the case of a printer friendly stylesheet, I use the following:

/* screen style */
.print_only { display: none; }

/* print stylesheet */
div.print_only { display: block; }
span.print_only { display: inline; }
.no_print { display: none; }

I used this when I needed to print a form containing values and the input fields were difficult to print. So I added the values wrapped in a span.print_only tag (div.print_only was used elsewhere) and then applied the .no_print class to the input fields. So on-screen you would see the input fields and when printed, only the values. If you wanted to get fancy you could use JS to update the values in the span tags when the fields were updated but that wasn't necessary in my case. Perhaps not the the most elegant solution but it worked for me!

YAML version :

overrides:
  - files: *-tests.js
    rules:
      no-param-reassign: 0

Example of specific rules for mocha tests :

You can also set a specific env for a folder, like this :

overrides:
  - files: test/*-tests.js
    env:
      mocha: true

This configuration will fix error message about describe and it not defined, only for your test folder:

/myproject/test/init-tests.js
6:1 error 'describe' is not defined no-undef
9:3 error 'it' is not defined no-undef

Just to follow up, problem solved! I mentioned mod_sec settings for my server as being the possible culprit as suggested and they were able to fix this issue. Here's what the tech agent said to tell them when you go to support:

Just let them know you need the rule 340163 whitelisted for domain.com as its hitting a mod_sec rule.

Apparently you will need to do this for each domain that is having the issue, but it works. Thanks for all the suggestions everyone!

This is a warning for usual. You can either disable it by

or simply use fopen_s like Microsoft has intended.

But be sure to use the pragma before other headers.

You need to set up SSH keys.

This GitHub page explains how to generate keys.

    valueSource.forEach { sum += $0.count }

using 100000 iterations on an vector of 10000 ints.

Edit: If changeing this numbers plausibly changes the resulting times you can have some confidence (not as good as inspecting the final assembly code) that the artificial benchmark has not been optimized away entirely. Of course it is best to messure the performance under real conditions. end Edit

for reference the used code:

#include <vector>

#define TEST_METHOD 1
const size_t TEST_ITERATIONS = 100000;
const size_t TEST_ARRAY_SIZE = 10000;

int main(int argc, char** argv) {

   std::vector<int> v(TEST_ARRAY_SIZE, 0);

   for(size_t i = 0; i < TEST_ITERATIONS; ++i) {
   #if TEST_METHOD == 1 
      memset(&v[0], 0, v.size() * sizeof v[0]);
   #elif TEST_METHOD == 2
      std::fill(v.begin(), v.end(), 0);
   #elif TEST_METHOD == 3
      for (std::vector<int>::iterator it=v.begin(), end=v.end(); it!=end; ++it) {
         *it = 0;
      }
   #elif TEST_METHOD == 4
      v.assign(v.size(),0);
   #endif
   }

   return EXIT_SUCCESS;
}

Conclusion: use std::fill (because, as others have said its most idiomatic)!

I ran across the same issue this morning. It turned out to be a simple issue. I had a query window open that was set to the single user database in the object explorer. The sp_who2 stored procedure did not show then connection. Once I closed it, I was able to set it to

There is no ENDIF in SQL.

The statement directly followig an IF is execute only when the if expression is true.

The BEGIN ... END construct is separate from the IF. It binds multiple statements together as a block that can be treated as if they were a single statement. Hence BEGIN ... END can be used directly after an IF and thus the whole block of code in the BEGIN .... END sequence will be either executed or skipped.

In your case I suspect the "(more code)" following FROM XXXXX is where your problem is.

Get the name or id of the image you would like to run, with this command:

docker images

The Docker run command is used in the following way:

docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

Below I have included the dispatch, name, publish, volume and restart options before specifying the image name or id:

docker run -d --name  container-name -p localhost:80:80 -v $HOME/myContainer/configDir:/myImage/configDir --restart=always image-name

Where:

--detach , -d        Run container in background and print container ID
--name                Assign a name to the container
--publish , -p        Publish a container’s port(s) to the host
--volume , -v        Bind mount a volume
--restart            Restart policy to apply when a container exits

For more information, please check out the official Docker run reference.

On the Zipped folder of the ADT you initially downloaded unzip and navigate to:

adt-bundle-windows-x86_64-20140702\eclipse\plugins

Copy all the executable jar files and paste them on the

C:\adt-bundle-windows-x86_64-20140702\adt-bundle-windows-x86_64-20140702\eclipse\plugins

directory (or wherever your adt is located).
Any executable jar files missing in the plugin folder will be added. You should be able to launch eclipse

This can be used. Passes all the tests.

In JavaScript:

pageX, pageY, screenX, screenY, clientX, and clientY returns a number which indicates the number of physical “CSS pixels” a point is from the reference point. The event point is where the user clicked, the reference point is a point in the upper left. These properties return the horizontal and vertical distance from that reference point.

pageX and pageY:
Relative to the top left of the fully rendered content area in the browser. This reference point is below the URL bar and back button in the upper left. This point could be anywhere in the browser window and can actually change location if there are embedded scrollable pages embedded within pages and the user moves a scrollbar.

screenX and screenY:
Relative to the top left of the physical screen/monitor, this reference point only moves if you increase or decrease the number of monitors or the monitor resolution.

clientX and clientY:
Relative to the upper left edge of the content area (the viewport) of the browser window. This point does not move even if the user moves a scrollbar from within the browser.

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

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

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

That's a great example. When &current is parsed into a text node it is converted to ¤t. When parsed into an attribute value, it is parsed as &current.

If you want &current in a text node, you should write &current in your markup.

The gory details are in the HTML5 parsing spec - Named Character Reference State

You need to use '2011-12-07' as the end point as a date without a time default to time 00:00:00.

So what you have actually written is interpreted as:

 SELECT users.* 
 FROM   users
 WHERE  created_at >= '2011-12-01 00:00:00' 
   AND  created_at <= '2011-12-06 00:00:00'

And your time stamp is: 2011-12-06 10:45:36 which is not between those points.
Change this too:

 SELECT users.* 
 FROM   users
 WHERE  created_at >= '2011-12-01'  -- Implied 00:00:00
   AND  created_at <  '2011-12-07'  -- Implied 00:00:00 and smaller than 
                                   --                  thus any time on 06

To expand on what @JoshuaMaddox said, in the MDN Learning Area, under the "Introduction to HTML" section, the Document and website structure sub-section says (bold/emphasis is by me):

Header

Usually a big strip across the top with a big heading and/or logo. This is where the main common information about a website usually stays from one webpage to another.

Navigation bar

Links to the site's main sections; usually represented by menu buttons, links, or tabs. Like the header, this content usually remains consistent from one webpage to another — having an inconsistent navigation on your website will just lead to confused, frustrated users. Many web designers consider the navigation bar to be part of the header rather than a individual component, but that's not a requirement; in fact some also argue that having the two separate is better for accessibility, as screen readers can read the two features better if they are separate.

Using an iframe to "render" a PDF will not work on all browsers; it depends on how the browser handles PDF files. Some browsers (such as Firefox and Chrome) have a built-in PDF rendered which allows them to display the PDF inline where as some older browsers (perhaps older versions of IE attempt to download the file instead).

Instead, I recommend checking out PDFObject which is a Javascript library to embed PDFs in HTML files. It handles browser compatibility pretty well and will most likely work on IE8.

In your HTML, you could set up a div to display the PDFs:

<div id="pdfRenderer"></div>

Then, you can have Javascript code to embed a PDF in that div:

var pdf = new PDFObject({
  url: "https://something.com/HTC_One_XL_User_Guide.pdf",
  id: "pdfRendered",
  pdfOpenParams: {
    view: "FitH"
  }
}).embed("pdfRenderer");

The original answer by Stoive is easily fixable by changing the last line to accommodate Blob:

function dataURItoBlob (dataURI) {
    // convert base64 to raw binary data held in a string
    // doesn't handle URLEncoded DataURIs
    var byteString;
    if (dataURI.split(',')[0].indexOf('base64') >= 0)
        byteString = atob(dataURI.split(',')[1]);
    else
        byteString = unescape(dataURI.split(',')[1]);
    // separate out the mime component
    var mimeString = dataURI.split(',')[0].split(':')[1].split(';')[0];

    // write the bytes of the string to an ArrayBuffer
    var ab = new ArrayBuffer(byteString.length);
    var ia = new Uint8Array(ab);
    for (var i = 0; i < byteString.length; i++) {
        ia[i] = byteString.charCodeAt(i);
    }

    // write the ArrayBuffer to a blob, and you're done
    return new Blob([ab],{type: mimeString});
}

There is no subquery needed with this statement, which is better written as

select u.* 
from Users u, CompanyRolesToUsers c
where u.Id = c.UserId        --join just specified here, perfectly fine
and u.lastname like '%fra%'
and c.CompanyRoleId in (2,3,4)

or

select u.* 
from Users u inner join CompanyRolesToUsers c
             on u.Id = c.UserId    --explicit "join" statement, no diff from above, just preference
where u.lastname like '%fra%'
  and c.CompanyRoleId in (2,3,4)

That being said, in LINQ it would be

from u in Users
from c in CompanyRolesToUsers 
where u.Id == c.UserId &&
      u.LastName.Contains("fra") &&
      selectedRoles.Contains(c.CompanyRoleId)
select u

or

from u in Users
join c in CompanyRolesToUsers 
       on u.Id equals c.UserId
where u.LastName.Contains("fra") &&
      selectedRoles.Contains(c.CompanyRoleId)
select u

Which again, are both respectable ways to represent this. I prefer the explicit "join" syntax in both cases myself, but there it is...

I kept losing history when using merge, so I ended up using rebase since in my case the two repositories are different enough not to end up merging at every commit:

git clone git@gitorious/projA.git projA
git clone git@gitorious/projB.git projB

cd projB
git remote add projA ../projA/
git fetch projA 
git rebase projA/master HEAD

=> resolve conflicts, then continue, as many times as needed...

git rebase --continue

Doing this leads to one project having all commits from projA followed by commits from projB

From the docs

• can I use the above method without any negative impact and without compromising a future appstore submission?

Bitcode will allow apple to optimise the app without you having to submit another build. But, you can only enable this feature if all frameworks and apps in the app bundle have this feature enabled. Having it helps, but not having it should not have any negative impact.

• What does the ENABLE_BITCODE actually do, will it be a non-optional requirement in the future?

For iOS apps, bitcode is the default, but optional. If you provide bitcode, all apps and frameworks in the app bundle need to include bitcode. For watchOS apps, bitcode is required.

• Are there any performance impacts if I enable / disable it?

The App Store and operating system optimize the installation of iOS and watchOS apps by tailoring app delivery to the capabilities of the user’s particular device, with minimal footprint. This optimization, called app thinning, lets you create apps that use the most device features, occupy minimum disk space, and accommodate future updates that can be applied by Apple. Faster downloads and more space for other apps and content provides a better user experience.

There should not be any performance impacts.

        for (var x = 0; x < length; x++) {
            var i = Math.floor(Math.random() * chars.length);
            pass += chars.charAt(i);
        }
        var pattern = false;
        var passwordpattern = new RegExp("[^a-zA-Z0-9+]+[0-9+]+[A-Z+]+[a-z+]");
        pattern = passwordpattern.test(pass);
        if (pattern == true)
            { alert(pass); }
        else
         { randomPassword(length); }
    }

try this to create the random password with atleast one special character

This should do what you want:

print tempfile.gettempdir()

For me on my Windows box, I get:

c:\temp

and on my Linux box I get:

/tmp

You need to use a regular expression, so that you can specify the global (g) flag:

var s = 'some+multi+word+string'.replace(/\+/g, ' ');

(I removed the $() around the string, as replace is not a jQuery method, so that won't work at all.)

You can get the device screen width via the screen.width property.
Sometimes it's also useful to use window.innerWidth (not typically found on mobile devices) instead of screen width when dealing with desktop browsers where the window size is often less than the device screen size.

Typically, when dealing with mobile devices AND desktop browsers I use the following:

 var width = (window.innerWidth > 0) ? window.innerWidth : screen.width;

One can also bind a function with ng-change event listener, if they need to run a bit more complex logic.

<div ng-app="myApp" ng-controller="myCtrl">      
        <input type='text' ng-model='name' ng-change='change()'>
        <br/> <span>changed {{counter}} times </span>
 </div>

...

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
      $scope.name = 'Australia';
      $scope.counter = 0;
      $scope.change = function() {
        $scope.counter++;
      };
});

Here's a way that allows for ties for the cut-off score.

author_count = Author.objects.count()
cut_off_score = Author.objects.order_by('-score').values_list('score')[min(30, author_count)]
top_authors = Author.objects.filter(score__gte=cut_off_score).order_by('last_name')

You may get more than 30 authors in top_authors this way and the min(30,author_count) is there incase you have fewer than 30 authors.

You can use parseInt(string, radix) to convert string value to integer like this code below

var votevalue = parseInt($('button').data('votevalue'));

I'm a friend of keeping the original files, so that you can still use the archived original ones and do new encodes from these fresh ones when the old transcodes are out of date. eg. migrating them from previously transocded mpeg2-hd to mpeg4-hd (and perhaps from mpeg4-hd to its successor in sometime). but all of these should be done from the original. any compression step will followed by a loss of quality. it will need some time to redo this again, but in my opinion it's worth the effort.

so, if you want to keep the originals, you can use the running time in seconds of you tapes times the maximum datarate of hdv (constants 27mbit/s I think) to get your needed storage capacity

The Internationalization API supports getting the user timezone, and is supported in all current browsers.

console.log(Intl.DateTimeFormat().resolvedOptions().timeZone)

Keep in mind that on some older browser versions that support the Internationalization API, the timeZone property is set to undefined rather than the user’s timezone string. As best as I can tell, at the time of writing (July 2017) all current browsers except for IE11 will return the user timezone as a string.

I was also seeing the same error on browser console for a project based out of require.js. As stated under MISMATCHED ANONYMOUS DEFINE() MODULES at https://requirejs.org/docs/errors.html, this error has multiple causes, the interesting one in my case being: If the problem is the use of loader plugins or anonymous modules but the RequireJS optimizer is not used for file bundling, use the RequireJS optimizer. As it turns out, Google Closure compiler was getting used to merge/minify the Javascript code during build. Solution was to remove the Google closure compiler, and instead use require.js's optimizer (r.js) to merge the js files.

The array_unique function is just one of the really useful native functions from PHP for dealing with arrays. I recently wrote a piece on them and the spread operator to modifying and manipulating PHP arrays:

https://wp-helpers.com/2021/02/27/php-arrays-functions-and-spread-operator-in-wp-context/

Assume time column is in timestamp integer msec format

1 day = 86400000 ms

Here you go:

day_divider = 86400000

df['time'] = df['time'].values.astype(dtype='datetime64[ms]') # for msec format

df['time'] = (df['time']/day_divider).values.astype(dtype='datetime64[D]') # for day format

try this declare the function outside the ready event.

    $(document).ready(function(){    
       setInterval(swapImages(),1000); 
    });


    function swapImages(){

    var active = $('.active'); 
    var next = ($('.active').next().length > 0) ? $('.active').next() :         $('#siteNewsHead img:first');
    active.removeClass('active');
    next.addClass('active');
}

I'm looking into using SSTJ for FFTs in Java. It can redirect via JNI to FFTW if the library is available or will use a pure Java implementation if not.

The reason it doesn't work in the link your provided is because you are trying to display a 300px column PLUS 52 columns the span 7 columns each. Shrink the number of columns and it works. You can't fit that many on the screen.

If you want to force the columns to fit try setting:

body {min-width:4150px;}

see my jsfiddle: http://jsfiddle.net/Mkq8L/6/ @mike I can't comment yet.

I've found that replacing the first part of the URL with IP address numbers instead of words worked for me.

For example use:

http://111.11.11.111/svn/Directory

instead of:

http://www.url.com/svn/Directory

In case of custom cell class. Just override:

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state

    if (selected) {
        [self setBackgroundColor: CELL_SELECTED_BG_COLOR];
        [self.contentView setBackgroundColor: CELL_SELECTED_BG_COLOR];
    }else{
        [self setBackgroundColor: [UIColor clearColor]];
        [self.contentView setBackgroundColor: [UIColor clearColor]];
    }
}

    $.event.special.rightclick = {
     bindType: "contextmenu",
        delegateType: "contextmenu"
      };

   $(document).on("rightclick", "div", function() {
   console.log("hello");
    return false;
    });

As well as using Package manager console to get nuget to update the project with Install-Package Microsoft.AspNet.WebApi.WebHost for missing GlobalConfiguration,

I needed Install-Package Microsoft.AspNet.WebApi.SelfHost for missing using System.Web.Http;

You can also use the following syntax for the strongly typed version:

<% using (Html.BeginForm<SomeController>(x=> x.SomeAction(), 
          FormMethod.Post, 
          new { enctype = "multipart/form-data" })) 
   { %>

I think its better to to do text-align center for div and let image take care of the height. Just specify a top and bottom padding for div to have space between image and div. Look at this example: http://jsfiddle.net/Tv9mG/

As I said in comments - you should always use parameters in your query - NEVER EVER concatenate together your SQL statements yourself.

Also: I would recommend to separate the click event handler from the actual code to insert the data.

So I would rewrite your code to be something like

In your web page's code-behind file (yourpage.aspx.cs)

private void button1_Click(object sender, EventArgs e)
{
      string connectionString = "Data Source=DELL-PC;initial catalog=AdventureWorks2008R2 ; User ID=sa;Password=sqlpass;Integrated Security=SSPI;";

      InsertData(connectionString,
                 textBox1.Text.Trim(),  -- first name
                 textBox2.Text.Trim(),  -- last name
                 textBox3.Text.Trim(),  -- user name
                 textBox4.Text.Trim(),  -- password
                 Convert.ToInt32(comboBox1.Text),  -- age
                 comboBox2.Text.Trim(), -- gender
                 textBox7.Text.Trim() );  -- contact
}

In some other code (e.g. a databaselayer.cs):

private void InsertData(string connectionString, string firstName, string lastname, string username, string password
                        int Age, string gender, string contact)
{
    // define INSERT query with parameters
    string query = "INSERT INTO dbo.regist (FirstName, Lastname, Username, Password, Age, Gender,Contact) " + 
                   "VALUES (@FirstName, @Lastname, @Username, @Password, @Age, @Gender, @Contact) ";

    // create connection and command
    using(SqlConnection cn = new SqlConnection(connectionString))
    using(SqlCommand cmd = new SqlCommand(query, cn))
    {
        // define parameters and their values
        cmd.Parameters.Add("@FirstName", SqlDbType.VarChar, 50).Value = firstName;
        cmd.Parameters.Add("@Lastname", SqlDbType.VarChar, 50).Value = lastName;
        cmd.Parameters.Add("@Username", SqlDbType.VarChar, 50).Value = userName;
        cmd.Parameters.Add("@Password", SqlDbType.VarChar, 50).Value = password;
        cmd.Parameters.Add("@Age", SqlDbType.Int).Value = age;
        cmd.Parameters.Add("@Gender", SqlDbType.VarChar, 50).Value = gender;
        cmd.Parameters.Add("@Contact", SqlDbType.VarChar, 50).Value = contact;

        // open connection, execute INSERT, close connection
        cn.Open();
        cmd.ExecuteNonQuery();
        cn.Close();
    }
}

Code like this:

• is not vulnerable to SQL injection attacks
• performs much better on SQL Server (since the query is parsed once into an execution plan, then cached and reused later on)
• separates the event handler (code-behind file) from your actual database code (putting things where they belong - helping to avoid "overweight" code-behinds with tons of spaghetti code, doing everything from handling UI events to database access - NOT a good design!)

Something like this, if want to go old-school.

<font color="blue">Sustaining : $60.00 USD - yearly</font>

Though a more modern approach would be to use a css style:

<td style="color:#0000ff">Sustaining : $60.00 USD - yearly</td>

There are of course even more general ways to do it.

First of all, there are still browsers out there that don't support those pseudo-elements (ie. :first-child, :last-child), so you have to 'deal' with this issue.

There is a good example how to make that work without using pseudo-elements:

http://www.darowski.com/tracesofinspiration/2010/01/11/this-newbies-first-impressions-of-haml-and-sass/

       -- see the divider pipe example.

I hope that was useful.

In Android Studio, Click on 'Tools' on the top tab bar of android studio

there you can clearly see which platform tool is missing , then just install that and your adb will start working properly.In Image You Can see every thing

if you dont have a database, you will have to hardcode the login details in your code, or read it from a flat file on disk.

There is no need for an UDF here. Column already provides cast method with DataType instance :

from pyspark.sql.types import DoubleType

changedTypedf = joindf.withColumn("label", joindf["show"].cast(DoubleType()))

or short string:

changedTypedf = joindf.withColumn("label", joindf["show"].cast("double"))

where canonical string names (other variations can be supported as well) correspond to simpleString value. So for atomic types:

from pyspark.sql import types 

for t in ['BinaryType', 'BooleanType', 'ByteType', 'DateType', 
          'DecimalType', 'DoubleType', 'FloatType', 'IntegerType', 
           'LongType', 'ShortType', 'StringType', 'TimestampType']:
    print(f"{t}: {getattr(types, t)().simpleString()}")

BinaryType: binary
BooleanType: boolean
ByteType: tinyint
DateType: date
DecimalType: decimal(10,0)
DoubleType: double
FloatType: float
IntegerType: int
LongType: bigint
ShortType: smallint
StringType: string
TimestampType: timestamp

and for example complex types

types.ArrayType(types.IntegerType()).simpleString()   

'array<int>'

types.MapType(types.StringType(), types.IntegerType()).simpleString()

'map<string,int>'

The erudite suggestions mentioned above will solve the problem in 99.99% of the cases. It was my luck that they did not. In my case it turned out I was including a header file from a different Windows project. Sure enough, at the very bottom of that file I found the directive:

#pragma comment(linker, "/subsystem:Windows")

Needless to say, removing this line solved my problem.

Use:

function remove-HSsoftware{
[cmdletbinding()]
param(
[parameter(Mandatory=$true,
ValuefromPipeline = $true,
HelpMessage="IdentifyingNumber can be retrieved with `"get-wmiobject -class win32_product`"")]
[ValidatePattern('{[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{12}}')]
[string[]]$ids,
[parameter(Mandatory=$false,
            ValuefromPipeline=$true,
            ValueFromPipelineByPropertyName=$true,
            HelpMessage="Computer name or IP adress to query via WMI")]
[Alias('hostname,CN,computername')]
[string[]]$computers
)
begin {}
process{
    if($computers -eq $null){
    $computers = Get-ADComputer -Filter * | Select dnshostname |%{$_.dnshostname}
    }
    foreach($computer in $computers){
        foreach($id in $ids){
            write-host "Trying to uninstall sofware with ID ", "$id", "from computer ", "$computer"
            $app = Get-WmiObject -class Win32_Product -Computername "$computer" -Filter "IdentifyingNumber = '$id'"
            $app | Remove-WmiObject

        }
    }
}
end{}}
 remove-hssoftware -ids "{8C299CF3-E529-414E-AKD8-68C23BA4CBE8}","{5A9C53A5-FF48-497D-AB86-1F6418B569B9}","{62092246-CFA2-4452-BEDB-62AC4BCE6C26}"

It's not fully tested, but it ran under PowerShell 4.

I've run the PS1 file as it is seen here. Letting it retrieve all the Systems from the AD and trying to uninstall multiple applications on all systems.

I've used the IdentifyingNumber to search for the Software cause of David Stetlers input.

Not tested:

1. Not adding ids to the call of the function in the script, instead starting the script with parameter IDs
2. Calling the script with more then 1 computer name not automatically retrieved from the function
3. Retrieving data from the pipe
4. Using IP addresses to connect to the system

What it does not:

1. It doesn't give any information if the software actually was found on any given system.
2. It does not give any information about failure or success of the deinstallation.

I wasn't able to use uninstall(). Trying that I got an error telling me that calling a method for an expression that has a value of NULL is not possible. Instead I used Remove-WmiObject, which seems to accomplish the same.

CAUTION: Without a computer name given it removes the software from ALL systems in the Active Directory.

My solution that would work on Chrome, Firefox, IE9, IE10 (Change the degrees as per your requirement):

.rotate-text {
  -webkit-transform: rotate(270deg);
  -moz-transform: rotate(270deg);
  -ms-transform: rotate(270deg);
  -o-transform: rotate(270deg);
  transform: rotate(270deg);
  filter: none; /*Mandatory for IE9 to show the vertical text correctly*/      
}

Got a bit confused from the top answers so I've wrote a small gist with examples for better understanding.

Option #1 - socket.settimeout()

Will raise an exception in case the sock.recv() waits for more than the defined timeout.

import socket

sock = socket.create_connection(('neverssl.com', 80))
timeout_seconds = 2
sock.settimeout(timeout_seconds)
sock.send(b'GET / HTTP/1.1\r\nHost: neverssl.com\r\n\r\n')
data = sock.recv(4096)
data = sock.recv(4096) # <- will raise a socket.timeout exception here

Option #2 - select.select()

Waits until data is sent until the timeout is reached. I've tweaked Daniel's answer so it will raise an exception

import select
import socket

def recv_timeout(sock, bytes_to_read, timeout_seconds):
    sock.setblocking(0)
    ready = select.select([sock], [], [], timeout_seconds)
    if ready[0]:
        return sock.recv(bytes_to_read)

    raise socket.timeout()

sock = socket.create_connection(('neverssl.com', 80))
timeout_seconds = 2
sock.send(b'GET / HTTP/1.1\r\nHost: neverssl.com\r\n\r\n')
data = recv_timeout(sock, 4096, timeout_seconds)
data = recv_timeout(sock, 4096, timeout_seconds) # <- will raise a socket.timeout exception here

Seems easiest to just add a

GET
/api/members/count

and return the total count of members

I know it's late in the day but might help someone else!

body,html {
  height: 100%;
}

.contentarea {

 /* 
  * replace 160px with the sum of height of all other divs 
  * inc padding, margins etc 
  */
  min-height: calc(100% - 160px); 
}

You can simply disable the textarea property like this:

textarea {
    resize: none;
}

To disable vertical or horizontal resizing, use

resize: vertical;

or

resize: horizontal;

To set automatic dimension for row height & estimated row height, ensure following steps to make, auto dimension effective for cell/row height layout.

• Assign and implement tableview dataSource and delegate
• Assign UITableViewAutomaticDimension to rowHeight & estimatedRowHeight
• Implement delegate/dataSource methods (i.e. heightForRowAt and return a value UITableViewAutomaticDimension to it)

-

Objective C:

// in ViewController.h
#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UITableViewDelegate, UITableViewDataSource>

  @property IBOutlet UITableView * table;

@end

// in ViewController.m

- (void)viewDidLoad {
    [super viewDidLoad];
    self.table.dataSource = self;
    self.table.delegate = self;

    self.table.rowHeight = UITableViewAutomaticDimension;
    self.table.estimatedRowHeight = UITableViewAutomaticDimension;
}

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {

    return UITableViewAutomaticDimension;
}

Swift:

@IBOutlet weak var table: UITableView!

override func viewDidLoad() {
    super.viewDidLoad()

    // Don't forget to set dataSource and delegate for table
    table.dataSource = self
    table.delegate = self

    // Set automatic dimensions for row height
    table.rowHeight = UITableViewAutomaticDimension
    table.estimatedRowHeight = UITableViewAutomaticDimension
}



// UITableViewAutomaticDimension calculates height of label contents/text
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableViewAutomaticDimension
}

For label instance in UITableviewCell

• Set number of lines = 0 (& line break mode = truncate tail)
• Set all constraints (top, bottom, right left) with respect to its superview/ cell container.
• Optional: Set minimum height for label, if you want minimum vertical area covered by label, even if there is no data.

Note: If you've more than one labels (UIElements) with dynamic length, which should be adjusted according to its content size: Adjust 'Content Hugging and Compression Resistance Priority` for labels which you want to expand/compress with higher priority.

Here in this example I set low hugging and high compression resistance priority, that leads to set more priority/importance for contents of second (yellow) label.

As ping works, but telnetto port 80 does not, the HTTP port 80 is closed on your machine. I assume that your browser's HTTP connection goes through a proxy (as browsing works, how else would you read stackoverflow?). You need to add some code to your python program, that handles the proxy, like described here:

Using an HTTP PROXY - Python

In Java, char is technically a "16-bit integer", so you can simply cast it to int and you'll get it's code. From Oracle:

The char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65,535 inclusive).

So you can simply cast it to int.

char registered = '®';
System.out.println(String.format("This is an int-code: %d", (int) registered));
System.out.println(String.format("And this is an hexa code: %x", (int) registered));

Try the Following Code Please. just only update two values.
1.your_database_name 2.table_name

    $host="localhost";
    $username="root";
    $password="";
    $dbname="your_database_name";
    $con = new mysqli($host, $username, $password,$dbname); 

        $sql_data="select * from table_name";
        $result_data=$con->query($sql_data);
        $results=array();
    filename = "Webinfopen.xls"; // File Name
    // Download file
    header("Content-Disposition: attachment; filename=\"$filename\"");
    header("Content-Type: application/vnd.ms-excel");

    $flag = false;
    while ($row = mysqli_fetch_assoc($result_data)) {
        if (!$flag) {
            // display field/column names as first row
            echo implode("\t", array_keys($row)) . "\r\n";
            $flag = true;
        }
        echo implode("\t", array_values($row)) . "\r\n";
    }
    ?>

There's now a drop down (at least since VS 2017.3.5) where you can specifically select C++17. The available options are (under project > Properties > C/C++ > Language > C++ Language Standard)

• ISO C++14 Standard. msvc command line option: /std:c++14
• ISO C++17 Standard. msvc command line option: /std:c++17
• The latest draft standard. msvc command line option: /std:c++latest

(I bet, once C++20 is out and more fully supported by Visual Studio it will be /std:c++20)

Using Google Play app signing feature & Google APIs integration in your app?

1. If you are using Google Play App Signing, don't forget that release signing-certificate fingerprint needed for Google API credentials is not the regular upload signing keys (SHA-1) you obtain from your app by this method:

2. You can obtain your release SHA-1 only from App signing page of your Google Play console as shown below:-

If you use Google Play app signing, Google re-signs your app. Thats how your signing-certificate fingerprint is given by Google Play App Signing as shown below:

All logging output is handled by the handlers; just add a logging.StreamHandler() to the root logger.

Here's an example configuring a stream handler (using stdout instead of the default stderr) and adding it to the root logger:

import logging
import sys

root = logging.getLogger()
root.setLevel(logging.DEBUG)

handler = logging.StreamHandler(sys.stdout)
handler.setLevel(logging.DEBUG)
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
handler.setFormatter(formatter)
root.addHandler(handler)

For everyone who looks example that works with Swift 2.2, Abizern code with modern do try catch handle of error

func databaseURL() -> NSURL? {

    let fileManager = NSFileManager.defaultManager()

    let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)

    if let documentDirectory:NSURL = urls.first { // No use of as? NSURL because let urls returns array of NSURL
        // This is where the database should be in the documents directory
        let finalDatabaseURL = documentDirectory.URLByAppendingPathComponent("OurFile.plist")

        if finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) {
            // The file already exists, so just return the URL
            return finalDatabaseURL
        } else {
            // Copy the initial file from the application bundle to the documents directory
            if let bundleURL = NSBundle.mainBundle().URLForResource("OurFile", withExtension: "plist") {

                do {
                    try fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL)
                } catch let error as NSError  {// Handle the error
                    print("Couldn't copy file to final location! Error:\(error.localisedDescription)")
                }

            } else {
                print("Couldn't find initial database in the bundle!")
            }
        }
    } else {
        print("Couldn't get documents directory!")
    }

    return nil
}

Update I've missed that new swift 2.0 have guard(Ruby unless analog), so with guard it is much shorter and more readable

func databaseURL() -> NSURL? {

let fileManager = NSFileManager.defaultManager()
let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)

// If array of path is empty the document folder not found
guard urls.count != 0 else {
    return nil
}

let finalDatabaseURL = urls.first!.URLByAppendingPathComponent("OurFile.plist")
// Check if file reachable, and if reacheble just return path
guard finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) else {
    // Check if file is exists in bundle folder
    if let bundleURL = NSBundle.mainBundle().URLForResource("OurFile", withExtension: "plist") {
        // if exist we will copy it
        do {
            try fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL)
        } catch let error as NSError { // Handle the error
            print("File copy failed! Error:\(error.localizedDescription)")
        }
    } else {
        print("Our file not exist in bundle folder")
        return nil
    }
    return finalDatabaseURL
}
return finalDatabaseURL 
}

One of the simplest ways to do this is like this

var totalWords = "my name is rahul.";_x000D_
var firstWord = totalWords.replace(/ .*/, '');_x000D_
alert(firstWord);_x000D_
console.log(firstWord);

System.out.println("hello"+"\n"+"world");

>>> i = 5
>>> print "Hello, world the number is " + i
TypeError: must be str, not int
>>> s = str(i)
>>> print "Hello, world the number is " + s
Hello, world the number is 5

man 7 daemon describes how to create daemon in great detail. My answer is just excerpt from this manual.

There are at least two types of daemons:

1. traditional SysV daemons (old-style),
2. systemd daemons (new-style).

SysV Daemons

If you are interested in traditional SysV daemon, you should implement the following steps:

1. Close all open file descriptors except standard input, output, and error (i.e. the first three file descriptors 0, 1, 2). This ensures that no accidentally passed file descriptor stays around in the daemon process. On Linux, this is best implemented by iterating through /proc/self/fd, with a fallback of iterating from file descriptor 3 to the value returned by getrlimit() for RLIMIT_NOFILE.
2. Reset all signal handlers to their default. This is best done by iterating through the available signals up to the limit of _NSIG and resetting them to SIG_DFL.
3. Reset the signal mask using sigprocmask().
4. Sanitize the environment block, removing or resetting environment variables that might negatively impact daemon runtime.
5. Call fork(), to create a background process.
6. In the child, call setsid() to detach from any terminal and create an independent session.
7. In the child, call fork() again, to ensure that the daemon can never re-acquire a terminal again.
8. Call exit() in the first child, so that only the second child (the actual daemon process) stays around. This ensures that the daemon process is re-parented to init/PID 1, as all daemons should be.
9. In the daemon process, connect /dev/null to standard input, output, and error.
10. In the daemon process, reset the umask to 0, so that the file modes passed to open(), mkdir() and suchlike directly control the access mode of the created files and directories.
11. In the daemon process, change the current directory to the root directory (/), in order to avoid that the daemon involuntarily blocks mount points from being unmounted.
12. In the daemon process, write the daemon PID (as returned by getpid()) to a PID file, for example /run/foobar.pid (for a hypothetical daemon "foobar") to ensure that the daemon cannot be started more than once. This must be implemented in race-free fashion so that the PID file is only updated when it is verified at the same time that the PID previously stored in the PID file no longer exists or belongs to a foreign process.
13. In the daemon process, drop privileges, if possible and applicable.
14. From the daemon process, notify the original process started that initialization is complete. This can be implemented via an unnamed pipe or similar communication channel that is created before the first fork() and hence available in both the original and the daemon process.
15. Call exit() in the original process. The process that invoked the daemon must be able to rely on that this exit() happens after initialization is complete and all external communication channels are established and accessible.

Note this warning:

The BSD daemon() function should not be used, as it implements only a subset of these steps.

A daemon that needs to provide compatibility with SysV systems should implement the scheme pointed out above. However, it is recommended to make this behavior optional and configurable via a command line argument to ease debugging as well as to simplify integration into systems using systemd.

Note that daemon() is not POSIX compliant.

New-Style Daemons

For new-style daemons the following steps are recommended:

1. If SIGTERM is received, shut down the daemon and exit cleanly.
2. If SIGHUP is received, reload the configuration files, if this applies.
3. Provide a correct exit code from the main daemon process, as this is used by the init system to detect service errors and problems. It is recommended to follow the exit code scheme as defined in the LSB recommendations for SysV init scripts.
4. If possible and applicable, expose the daemon's control interface via the D-Bus IPC system and grab a bus name as last step of initialization.
5. For integration in systemd, provide a .service unit file that carries information about starting, stopping and otherwise maintaining the daemon. See systemd.service(5) for details.
6. As much as possible, rely on the init system's functionality to limit the access of the daemon to files, services and other resources, i.e. in the case of systemd, rely on systemd's resource limit control instead of implementing your own, rely on systemd's privilege dropping code instead of implementing it in the daemon, and similar. See systemd.exec(5) for the available controls.
7. If D-Bus is used, make your daemon bus-activatable by supplying a D-Bus service activation configuration file. This has multiple advantages: your daemon may be started lazily on-demand; it may be started in parallel to other daemons requiring it — which maximizes parallelization and boot-up speed; your daemon can be restarted on failure without losing any bus requests, as the bus queues requests for activatable services. See below for details.
8. If your daemon provides services to other local processes or remote clients via a socket, it should be made socket-activatable following the scheme pointed out below. Like D-Bus activation, this enables on-demand starting of services as well as it allows improved parallelization of service start-up. Also, for state-less protocols (such as syslog, DNS), a daemon implementing socket-based activation can be restarted without losing a single request. See below for details.
9. If applicable, a daemon should notify the init system about startup completion or status updates via the sd_notify(3) interface.
10. Instead of using the syslog() call to log directly to the system syslog service, a new-style daemon may choose to simply log to standard error via fprintf(), which is then forwarded to syslog by the init system. If log levels are necessary, these can be encoded by prefixing individual log lines with strings like "<4>" (for log level 4 "WARNING" in the syslog priority scheme), following a similar style as the Linux kernel's printk() level system. For details, see sd-daemon(3) and systemd.exec(5).

Since they are already inline-block child elements, you can set text-align:center on the parent without having to set a width or margin:0px auto on the child. Meaning it will work for dynamically generated content with varying widths.

.img_container, .img_container2 {
    text-align: center;
}

This will center the child within both div containers.

UPDATE:

For vertical centering, you can use the calc() function assuming the height of the icon is known.

.img_container > i, .img_container2 > i {
    position:relative;
    top: calc(50% - 10px); /* 50% - 3/4 of icon height */
}

jsFiddle demo - it works.

For what it's worth - you can also use vertical-align:middle assuming display:table-cell is set on the parent.

I'd recommend making "apple" its own class. You should avoid the starts-with/ends-with if you can because being able to select using div.apple would be a lot faster. That's the more elegant solution. Don't be afraid to split things out into separate classes if it makes the task simpler/faster.
