The LDF is the transaction log. It keeps a record of everything done to the database for rollback purposes.

You do not want to delete, but you can shrink it with the dbcc shrinkfile command. You can also right-click on the database in SQL Server Management Studio and go to Tasks > Shrink.

No, there are definitely times where you would not want to use [unowned self]. Sometimes you want the closure to capture self in order to make sure that it is still around by the time the closure is called.

Example: Making an asynchronous network request

If you are making an asynchronous network request you do want the closure to retain self for when the request finishes. That object may have otherwise been deallocated but you still want to be able to handle the request finishing.

When to use unowned self or weak self

The only time where you really want to use [unowned self] or [weak self] is when you would create a strong reference cycle. A strong reference cycle is when there is a loop of ownership where objects end up owning each other (maybe through a third party) and therefore they will never be deallocated because they are both ensuring that each other stick around.

In the specific case of a closure, you just need to realize that any variable that is referenced inside of it, gets "owned" by the closure. As long as the closure is around, those objects are guaranteed to be around. The only way to stop that ownership, is to do the [unowned self] or [weak self]. So if a class owns a closure, and that closure captures a strong reference to that class, then you have a strong reference cycle between the closure and the class. This also includes if the class owns something that owns the closure.

Specifically in the example from the video

In the example on the slide, TempNotifier owns the closure through the onChange member variable. If they did not declare self as unowned, the closure would also own self creating a strong reference cycle.

Difference between unowned and weak

The difference between unowned and weak is that weak is declared as an Optional while unowned is not. By declaring it weak you get to handle the case that it might be nil inside the closure at some point. If you try to access an unowned variable that happens to be nil, it will crash the whole program. So only use unowned when you are positive that variable will always be around while the closure is around

Like Pekka said, it should work this way. I can't reproduce the problem with this self-contained example:

<?php
    $pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

    $pdo->exec('
        CREATE TEMPORARY TABLE soFoo (
            id int auto_increment,
            first int,
            last int,
            whenadded DATETIME,
            primary key(id)
        )
    ');
    $pdo->exec('INSERT INTO soFoo (first,last,whenadded) VALUES (0,1,Now())');
    $pdo->exec('INSERT INTO soFoo (first,last,whenadded) VALUES (0,2,Now())');
    $pdo->exec('INSERT INTO soFoo (first,last,whenadded) VALUES (0,3,Now())');

    foreach( $pdo->query('SELECT * FROM soFoo', PDO::FETCH_ASSOC) as $row ) {
        echo join(' | ', $row), "\n";
    }

Which (currently) prints

1 | 0 | 1 | 2012-03-23 16:00:18
2 | 0 | 2 | 2012-03-23 16:00:18
3 | 0 | 3 | 2012-03-23 16:00:18

And here's (almost) the same script using a TIMESTAMP field and DEFAULT CURRENT_TIMESTAMP:

<?php
    $pdo = new PDO('mysql:host=localhost;dbname=test;charset=utf8', 'localonly', 'localonly');
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    $pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

    $pdo->exec('
        CREATE TEMPORARY TABLE soFoo (
            id int auto_increment,
            first int,
            last int,
            whenadded TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
            primary key(id)
        )
    ');
    $pdo->exec('INSERT INTO soFoo (first,last) VALUES (0,1)');
    $pdo->exec('INSERT INTO soFoo (first,last) VALUES (0,2)');
    sleep(1);
    $pdo->exec('INSERT INTO soFoo (first,last) VALUES (0,3)');

    foreach( $pdo->query('SELECT * FROM soFoo', PDO::FETCH_ASSOC) as $row ) {
        echo join(' | ', $row), "\n";
    }

Conveniently, the timestamp is converted to the same datetime string representation as in the first example - at least with my PHP/PDO/mysqlnd version.

You can use # at the beginning of a line to start a comment (whitespaces before # are allowed):

# do some stuff
RUN apt-get update \
    # install some packages
    apt-get install -y cron

#'s in the middle of a string are passed to the command itself, e.g.:

RUN echo 'we are running some # of cool things'

I have tried a lot of ways to solve this. But I am failed again and again. Then I did this:

Open Git Bash > go to your directory > paste the git clone https://[email protected]/*******.git after that a command prompt will be shown to give the login credentials. Give the credentials and clone your project.

Another option is to search the XML as a string by converting it to a string and then using LIKE. However as a computed column can't be part of a WHERE clause you need to wrap it in another SELECT like this:

SELECT * FROM
    (SELECT *, CONVERT(varchar(MAX), [COLUMNA]) as [XMLDataString] FROM TABLE) x
WHERE [XMLDataString] like '%Test%'

In my case Microsoft.Common.CurrentVersion.targets was corrupted. I copied this file from other system and it worked.

From http://www.codeproject.com/KB/recipes/wildcardtoregex.aspx:

public static string WildcardToRegex(string pattern)
{
    return "^" + Regex.Escape(pattern)
                      .Replace(@"\*", ".*")
                      .Replace(@"\?", ".")
               + "$";
}

So something like foo*.xls? will get transformed to ^foo.*\.xls.$.

You've encountered a local time discontinuity:

When local standard time was about to reach Sunday, 1. January 1928, 00:00:00 clocks were turned backward 0:05:52 hours to Saturday, 31. December 1927, 23:54:08 local standard time instead

This is not particularly strange and has happened pretty much everywhere at one time or another as timezones were switched or changed due to political or administrative actions.

Use the type() builtin function:

>>> i = 123
>>> type(i)
<type 'int'>
>>> type(i) is int
True
>>> i = 123.456
>>> type(i)
<type 'float'>
>>> type(i) is float
True

To check if a variable is of a given type, use isinstance:

>>> i = 123
>>> isinstance(i, int)
True
>>> isinstance(i, (float, str, set, dict))
False

Note that Python doesn't have the same types as C/C++, which appears to be your question.

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

The relevant paragraph:

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

This makes lots of sense.

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

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

Cookies are only sent at the time of the request, and therefore cannot be retrieved as soon as it is assigned (only available after reloading).

Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.

If output exists prior to calling this function, setcookie() will fail and return FALSE. If setcookie() successfully runs, it will return TRUE. This does not indicate whether the user accepted the cookie.

Cookies will not become visible until the next loading of a page that the cookie should be visible for. To test if a cookie was successfully set, check for the cookie on a next loading page before the cookie expires. Expire time is set via the expire parameter. A nice way to debug the existence of cookies is by simply calling print_r($_COOKIE);.

Most recent answer (for Angular 8+):

this.http.post("your-url",params,{responseType:'arraybuffer' as 'json'}).subscribe(
  (res) => {
    this.showpdf(res);
  }
)};

public Content:SafeResourceUrl;
showpdf(response:ArrayBuffer) {
  var file = new Blob([response], {type: 'application/pdf'});
  var fileURL = URL.createObjectURL(file);
  this.Content = this.sanitizer.bypassSecurityTrustResourceUrl(fileURL);
}

  HTML :

  <embed [src]="Content" style="width:200px;height:200px;" type="application/pdf" />

You can do:

<form name="loginform" novalidate ng-submit="loginform.$valid && login.submit()">

No need for controller checks.

If you call only reset() function, the form controls will not set to pristine state. android.io docs have a solution for this issue.

component.ts

  active = true; 

  resetForm() {
      this.form.reset();
      this.active = false;
      setTimeout(() => this.active = true, 0);
  }

component.html

<form *ngIf="active">

((TextBox)GridView1.Rows[e.NewEditIndex].Cells[3].Controls[0]).Enabled = false;

If you are willing to part with some money, JNIWrapper is a useful library with a Winpack, you will be able to get file system events on certain files. Unfortunately windows only.

See https://www.teamdev.com/jniwrapper.

Otherwise, resorting to native code is not always a bad thing especially when the best on offer is a polling mechanism as against a native event.

I've noticed that Java file system operations can be slow on some computers and can easily affect the application's performance if not handled well.

You can use find

find . -type d > output.txt

or tree

tree -d > output.txt

tree, If not installed on your system.

If you are using ubuntu

sudo apt-get install tree

If you are using mac os.

brew install tree

Use the id of the element to do the same.

document.getElementById(id).style.visibility = 'hidden';

this works well for me

    arglen=$#
    argparam=$*
    if [ $arglen -eq '3' ];
    then
            echo Valid Number of arguments
            echo "Arguments are $*"
    else
            echo only four arguments are allowed
    fi

To complete the other answers, in lodash 4 to ignore only undefined and null (And not properties like false) you can use a predicate in _.pickBy:

_.pickBy(obj, v !== null && v !== undefined)

Example below :

const obj = { a: undefined, b: 123, c: true, d: false, e: null};_x000D_
_x000D_
const filteredObject = _.pickBy(obj, v => v !== null && v !== undefined);_x000D_
_x000D_
console.log = (obj) => document.write(JSON.stringify(filteredObject, null, 2));_x000D_
console.log(filteredObject);

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.10/lodash.js"></script>

Try this;

1. create a variable as below

   SET "SolutionDir=C:\Test projects\Automation tests\bin\Debug"**
   

2. Then replace the path with variable. Make sure to add quotes for starts and end

   vstest.console.exe "%SolutionDir%\Automation.Specs.dll"
   

Here an alternative using SUBSTRING

SELECT
            SUBSTRING([Field], LEN([Field]) - 2, 3) [Right3],
            SUBSTRING([Field], 0, LEN([Field]) - 2) [TheRest]
    FROM 
            [Fields]

I probably prefer to invoke the ToTitleCase from CultureInfo (System.Globalization) than Thread.CurrentThread (System.Threading)

string s = "THIS IS MY TEXT RIGHT NOW";
s = CultureInfo.CurrentCulture.TextInfo.ToTitleCase(s.ToLower());

but it should be the same as jspcal solution

EDIT

Actually those solutions are not the same: CurrentThread --calls--> CultureInfo!

System.Threading.Thread.CurrentThread.CurrentCulture

string s = "THIS IS MY TEXT RIGHT NOW";
s = System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo.ToTitleCase(s.ToLower());

IL_0000:  ldstr       "THIS IS MY TEXT RIGHT NOW"
IL_0005:  stloc.0     // s
IL_0006:  call        System.Threading.Thread.get_CurrentThread
IL_000B:  callvirt    System.Threading.Thread.get_CurrentCulture
IL_0010:  callvirt    System.Globalization.CultureInfo.get_TextInfo
IL_0015:  ldloc.0     // s
IL_0016:  callvirt    System.String.ToLower
IL_001B:  callvirt    System.Globalization.TextInfo.ToTitleCase
IL_0020:  stloc.0     // s

System.Globalization.CultureInfo.CurrentCulture

string s = "THIS IS MY TEXT RIGHT NOW";
s = System.Globalization.CultureInfo.CurrentCulture.TextInfo.ToTitleCase(s.ToLower());

IL_0000:  ldstr       "THIS IS MY TEXT RIGHT NOW"
IL_0005:  stloc.0     // s
IL_0006:  call        System.Globalization.CultureInfo.get_CurrentCulture
IL_000B:  callvirt    System.Globalization.CultureInfo.get_TextInfo
IL_0010:  ldloc.0     // s
IL_0011:  callvirt    System.String.ToLower
IL_0016:  callvirt    System.Globalization.TextInfo.ToTitleCase

I think returning 0 for succ/1 for fail (glenn jackman) and olibre's clear and explanatory answer says it all; just to mention a kind of "combo" approach for cases where results are not binary and you'd prefer to set a variable rather than "echoing out" a result (for instance if your function is ALSO suppose to echo something, this approach will not work). What then? (below is Bourne Shell)

# Syntax _w (wrapReturn)
# arg1 : method to wrap
# arg2 : variable to set
_w(){
eval $1
read $2 <<EOF
$?
EOF
eval $2=\$$2
}

as in (yep, the example is somewhat silly, it's just an.. example)

getDay(){
  d=`date '+%d'`
  [ $d -gt 255 ] && echo "Oh no a return value is 0-255!" && BAIL=0 # this will of course never happen, it's just to clarify the nature of returns
  return $d
}

dayzToSalary(){
  daysLeft=0
  if [ $1 -lt 26 ]; then 
      daysLeft=`expr 25 - $1`
  else
     lastDayInMonth=`date -d "`date +%Y%m01` +1 month -1 day" +%d`
     rest=`expr $lastDayInMonth - 25`
     daysLeft=`expr 25 + $rest`
  fi
  echo "Mate, it's another $daysLeft days.."
}

# main
_w getDay DAY # call getDay, save the result in the DAY variable
dayzToSalary $DAY

You could use Regex.Split:

string[] tokens = Regex.Split(input, @"\r?\n|\r");

Edit: added |\r to account for (older) Mac line terminators.

Just run composer install - it will make your vendor directory reflect dependencies in composer.lock file.

In other words - it will delete any vendor which is missing in composer.lock.

Please update the composer itself before running this.

• Write the file while editing - :w newname - to create a copy.
• Start editing the new copy - :e#.
• (Optionally) remove the old copy - :!rm oldname.

On Windows, the optional 3rd step changes a little:

• (Optionally) remove old Windows copy - :!del oldname.

Use:

num_lines = sum(1 for line in open('data.txt'))
print(num_lines)

That will work.

With javascript all arrays are flexible. You can simply do something like the following:

var myArray = [];

myArray.push(object);
myArray.push(anotherObject);
// ...

As of Swift 2.1 NSArrays have containsObjectthat can be used like so:

if myArray.containsObject(objectImCheckingFor){
    //myArray has the objectImCheckingFor
}

Opening a pdf using google docs is a bad idea in terms of user experience. It is really slow and unresponsive.

Solution after API 21

Since api 21, we have PdfRenderer which helps converting a pdf to Bitmap. I've never used it but is seems easy enough.

Solution for any api level

Other solution is to download the PDF and pass it via Intent to a dedicated PDF app which will do a banger job displaying it. Fast and nice user experience, especially if this feature is not central in your app.

Use this code to download and open the PDF

public class PdfOpenHelper {

public static void openPdfFromUrl(final String pdfUrl, final Activity activity){
    Observable.fromCallable(new Callable<File>() {
        @Override
        public File call() throws Exception {
            try{
                URL url = new URL(pdfUrl);
                URLConnection connection = url.openConnection();
                connection.connect();

                // download the file
                InputStream input = new BufferedInputStream(connection.getInputStream());
                File dir = new File(activity.getFilesDir(), "/shared_pdf");
                dir.mkdir();
                File file = new File(dir, "temp.pdf");
                OutputStream output = new FileOutputStream(file);

                byte data[] = new byte[1024];
                long total = 0;
                int count;
                while ((count = input.read(data)) != -1) {
                    total += count;
                    output.write(data, 0, count);
                }

                output.flush();
                output.close();
                input.close();
                return file;
            } catch (IOException e) {
                e.printStackTrace();
            }
            return null;
        }
    })
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Subscriber<File>() {
                @Override
                public void onCompleted() {

                }

                @Override
                public void onError(Throwable e) {

                }

                @Override
                public void onNext(File file) {
                    String authority = activity.getApplicationContext().getPackageName() + ".fileprovider";
                    Uri uriToFile = FileProvider.getUriForFile(activity, authority, file);

                    Intent shareIntent = new Intent(Intent.ACTION_VIEW);
                    shareIntent.setDataAndType(uriToFile, "application/pdf");
                    shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                    if (shareIntent.resolveActivity(activity.getPackageManager()) != null) {
                        activity.startActivity(shareIntent);
                    }
                }
            });
}

}

For the Intent to work, you need to create a FileProvider to grant permission to the receiving app to open the file.

Here is how you implement it: In your Manifest:

    <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="${applicationId}.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">

        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths" />

    </provider>

Finally create a file_paths.xml file in the resources foler

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <files-path name="shared_pdf" path="shared_pdf"/>

Hope this helps =)

Nick's answer has really helped me, but I realised it could be tweaked slightly, to avoid an extra class, ValueDescription. I remembered that there exists a KeyValuePair class already in the framework, so this can be used instead.

The code changes only slightly :

public static IEnumerable<KeyValuePair<string, string>> GetAllValuesAndDescriptions<TEnum>() where TEnum : struct, IConvertible, IComparable, IFormattable
    {
        if (!typeof(TEnum).IsEnum)
        {
            throw new ArgumentException("TEnum must be an Enumeration type");
        }

        return from e in Enum.GetValues(typeof(TEnum)).Cast<Enum>()
               select new KeyValuePair<string, string>(e.ToString(),  e.Description());
    }


public IEnumerable<KeyValuePair<string, string>> PlayerClassList
{
   get
   {
       return EnumHelper.GetAllValuesAndDescriptions<PlayerClass>();
   }
}

and finally the XAML :

<ComboBox ItemSource="{Binding Path=PlayerClassList}"
          DisplayMemberPath="Value"
          SelectedValuePath="Key"
          SelectedValue="{Binding Path=SelectedClass}" />

I hope this is helpful to others.

Get the port number using netstat:

netstat -b

And then use the Wireshark filter:

tcp.port == portnumber

You're trying to access a JSON, not JSONP.

Notice the difference between your source:

https://api.flightstats.com/flex/schedules/rest/v1/json/flight/AA/100/departing/2013/10/4?appId=19d57e69&appKey=e0ea60854c1205af43fd7b1203005d59&callback=?

And actual JSONP (a wrapping function):

http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=processJSON&tags=monkey&tagmode=any&format=json

Search for JSON + CORS/Cross-domain policy and you will find hundreds of SO threads on this very topic.

I know everybody is ethically against this, but I understand there are reasons of practical joking where this is desired. I think Chrome took a solid stance on this by enforcing a mandatory one second separation time between alert messages. This gives the visitor just enough time to close the page or refresh if they're stuck on an annoying prank site.

So to answer your question, it's all a matter of timing. If you alert more than once per second, Chrome will create that checkbox. Here's a simple example of a workaround:

var countdown = 99;
function annoy(){
    if(countdown>0){
        alert(countdown+" bottles of beer on the wall, "+countdown+" bottles of beer! Take one down, pass it around, "+(countdown-1)+" bottles of beer on the wall!");
        countdown--;

        // Time must always be 1000 milliseconds, 999 or less causes the checkbox to appear
        setTimeout(function(){
            annoy();
        }, 1000);
    }
}

// Don't alert right away or Chrome will catch you
setTimeout(function(){
    annoy();
}, 1000);

bool_series=pd.notnull(dat["x"])
dat=dat[bool_series]

From the documentation, you can apparently use either command to keep the file in the project history. Looks like you want remove, since it also deletes the file from the working directory.

From the Mercurial book at http://hgbook.red-bean.com/read/:

Removing a file does not affect its history. It is important to understand that removing a file has only two effects. It removes the current version of the file from the working directory. It stops Mercurial from tracking changes to the file, from the time of the next commit. Removing a file does not in any way alter the history of the file.

The man page hg(1) says this about forget:

Mark the specified files so they will no longer be tracked after the next commit. This only removes files from the current branch, not from the entire project history, and it does not delete them from the working directory.

And this about remove:

Schedule the indicated files for removal from the repository. This only removes files from the current branch, not from the entire project history.

Let’s assume, your old app.module.ts may look similar to this :

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';

@NgModule({
    imports: [ BrowserModule ],
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ]
})

export class AppModule { }

Now import FormsModule in your app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';

@NgModule({
    imports: [ BrowserModule, FormsModule ],
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ]
})

export class AppModule { }

Use:

grep somethingtosearch *.log

and the filenames will be printed out along with the matches.

If you're using angularJS or some variant of the Q promise library, then you have a .all() method that solves this exact problem.

var savePromises = [];
angular.forEach(models, function(model){
  savePromises.push(
    model.saveToServer()
  )
});

$q.all(savePromises).then(
  function success(results){...},
  function failed(results){...}
);

see the full API:

It`s definitely better to use COMPOSITE UNIQUE KEY, as @GranadaCoder offered, a little bit tricky example though:

ALTER IGNORE TABLE table_name ADD UNIQUES INDEX idx_name(some_id, another_id, one_more_id);

On CentOS EL 6 and perhaps on earlier versions there is one way to get into this same mess.

Install CentOS EL6 with a minimal installation. For example I used kickstart to install the following:

%packages
@core
acpid
bison
cmake
dhcp-common
flex
gcc
gcc-c++
git
libaio-devel
make
man
ncurses-devel
perl
ntp
ntpdate
pciutils
tar
tcpdump
wget
%end

You will find that one of the dependencies of the above list is mysql-libs. I found that my system has a default my.cnf in /etc and this contains:

[mysqld]
dataddir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

When you build from the Generic Linux (Architecture Independent), Compressed TAR Archive your default data directory is /usr/local/mysql/data which conflicts with the /etc/my.cnf already present which defines datadir=/var/lib/mysql. Also the pid-file defined in the same file does not have permissions for the mysql user/group to write to it in /var/run/mysqld.

A quick remedy is to mv /etc/my.cnf /etc/my.cnf.old which should get your generic source procedure working.

Of course the experience is different of you use the source RPMs.

If you need url, not route name, you do not need to use/require any other classes:

url()->current();

This will get you 90% of the way there ; )

window.$ = document.querySelectorAll.bind(document)

For Ajax, the Fetch API is now supported on the current version of every major browser. For $.ready(), DOMContentLoaded has near universal support. You Might Not Need jQuery gives equivalent native methods for other common jQuery functions.

Zepto offers similar functionality but weighs in at 10K zipped. There are custom Ajax builds for jQuery and Zepto as well as some micro frameworks, but jQuery/Zepto have solid support and 10KB is only ~1 second on a 56K modem.

It seems to work:

substring_index ( substring_index ( context,',',1 ), ',', -1) 
substring_index ( substring_index ( context,',',2 ), ',', -1)
substring_index ( substring_index ( context,',',3 ), ',', -1)
substring_index ( substring_index ( context,',',4 ), ',', -1)

it means 1st value, 2nd, 3rd, etc.

Explanation:

The inner substring_index returns the first n values that are comma separated. So if your original string is "34,7,23,89", substring_index( context,',', 3) returns "34,7,23".
The outer substring_index takes the value returned by the inner substring_index and the -1 allows you to take the last value. So you get "23" from the "34,7,23".
Instead of -1 if you specify -2, you'll get "7,23", because it took the last two values.

Example:

select * from MyTable where substring_index(substring_index(prices,',',1),',',-1)=3382;

Here, prices is the name of a column in MyTable.

Another way is to download JDK 1.7 and change the path from Android Studio in the error message..and choose Home folder who is contained in Jdk 1.7 folder

Here is a ridiculously brute force answer:

I modified the gradlew script. Here is my new exec command at the end of the file in the

exec "$JAVACMD" "${JVM_OPTS[@]}" -classpath "$CLASSPATH" org.gradle.wrapper.GradleWrapperMain "$@" **| grep -v "libpng warning:"**

You can use

find $PWD 

in bash

Adding to @Hendrik Eichler Answer, the n vh uses n% of the viewport's initial containing block.

.element{
    height: 50vh; /* Would mean 50% of Viewport height */
    width:  75vw; /* Would mean 75% of Viewport width*/
}

Also, the viewport height is for devices of any resolution, the view port height, width is one of the best ways (similar to css design using % values but basing it on the device's view port height and width)

vh
Equal to 1% of the height of the viewport's initial containing block.

vw
Equal to 1% of the width of the viewport's initial containing block.

vi
Equal to 1% of the size of the initial containing block, in the direction of the root element’s inline axis.

vb
Equal to 1% of the size of the initial containing block, in the direction of the root element’s block axis.

vmin
Equal to the smaller of vw and vh.

vmax
Equal to the larger of vw and vh.

For me, it said Module did not found and not worked. Finally, I found this solution and worked.

<img v-bind:src="require('@' + baseUrl + 'path/path' + obj.key +'.png')"/>

Needed to add '@' at the beginning of the local path.

Edit 09/2016: In Python 3 and up use urllib.request instead of urllib2

Actually the simplest way is:

import urllib2  # the lib that handles the url stuff

data = urllib2.urlopen(target_url) # it's a file like object and works just like a file
for line in data: # files are iterable
    print line

You don't even need "readlines", as Will suggested. You could even shorten it to: ^*

import urllib2

for line in urllib2.urlopen(target_url):
    print line

But remember in Python, readability matters.

However, this is the simplest way but not the safe way because most of the time with network programming, you don't know if the amount of data to expect will be respected. So you'd generally better read a fixed and reasonable amount of data, something you know to be enough for the data you expect but will prevent your script from been flooded:

import urllib2

data = urllib2.urlopen("http://www.google.com").read(20000) # read only 20 000 chars
data = data.split("\n") # then split it into lines

for line in data:
    print line

^{* Second example in Python 3:}

import urllib.request  # the lib that handles the url stuff

for line in urllib.request.urlopen(target_url):
    print(line.decode('utf-8')) #utf-8 or iso8859-1 or whatever the page encoding scheme is

Hello guys I am stucked with this. I've a Document Profile who has a reference to User,and I've tried to list the profiles where user ref is not null (because I already filtered by rol during the population), but after googleing a few hours I cannot figure out how to get this. I have this query:

const profiles = await Profile.find({ user: {$exists: true,  $ne: null }})
                            .select("-gallery")
                            .sort( {_id: -1} )
                            .skip( skip )
                            .limit(10)
                            .select(exclude)
                            .populate({
                                path: 'user',
                                match: { role: {$eq: customer}},
                                select: '-password -verified -_id -__v'
                              })

                            .exec();

And I get this result, how can I remove from the results the user:null colletions? . I meant, I dont want to get the profile when user is null (the role does not match).

            }
        }
    ],

}

Thanks in advance.

A little verbose, but self documenting...

Dim strEmpty() As String = Enumerable.Empty(Of String).ToArray

if (listView1.Items.Count > 0)
{
    listView1.Items[0].Selected = true;
    listView1.Select();
}

list items do not appear selected unless the control has the focus (or you set the HideSelection property to false)

The best choice to me was to create a directive to do the work, because $location.hash() and $anchorScroll() hijack the URL creating lots of problems to my SPA routing.

MyModule.directive('myAnchor', function() {
  return {
    restrict: 'A',
    require: '?ngModel',
    link: function(scope, elem, attrs, ngModel) {
      return elem.bind('click', function() {
        //other stuff ...
        var el;
        el = document.getElementById(attrs['myAnchor']);
        return el.scrollIntoView();
      });      
    }
  };
});

Let's say you have a path with a file in this format:

/dirA/dirB/dirC/filename.file

Now you only want the path which includes four "/". Type

$ echo "/dirA/dirB/dirC/filename.file" | cut -f1-4 -d"/"

and your output will be

/dirA/dirB/dirC

The advantage of using cut is that you can also cut out the uppest directory as well as the file (in this example), so if you type

$ echo "/dirA/dirB/dirC/filename.file" | cut -f1-3 -d"/"

your output would be

/dirA/dirB

Though you can do the same from the other side of the string, it would not make that much sense in this case as typing

$ echo "/dirA/dirB/dirC/filename.file" | cut -f2-4 -d"/"

results in

dirA/dirB/dirC

In some other cases the last case might also be helpful. Mind that there is no "/" at the beginning of the last output.

Ideally the background property would allow us to layer various backgrounds similar to the background image layering detailed at http://www.css3.info/preview/multiple-backgrounds/. Unfortunately, at least in Chrome (40.0.2214.115), adding an rgba background alongside a url() image background seems to break the property.

The solution I've found is to render the rgba layer as a 1px*1px Base64 encoded image and inline it.

.the-div:hover {
  background-image:url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR42mNgkAQAABwAGkn5GOoAAAAASUVORK5CYII=), url("the-image.png");
}

for base64 encoded 1*1 pixel images I used http://px64.net/

Here is your jsfiddle with these changes made. http://jsfiddle.net/325Ft/49/ (I also swapped the image to one that still exists on the internet)

imageView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

It depends what is a use of those tables, but you might consider putting trigger on original table on insert and update. When insert or update is done, update the second table based on only one item from the original table. It will be quicker.

I'm using xdebug for watch this values in VSCode with the respective extension and CI v2.x. I add the expresion $this->db->last_query() in the watch section, and I add xdebugSettings node like these lines for get non truncate value in the launch.json.

{
  "name": "Launch currently open script",
  "type": "php",
  "request": "launch",
  "program": "${file}",
  "cwd": "${fileDirname}",
  "port": 9000,
  "xdebugSettings": {
    "max_data": -1,
    "max_children": -1
  }
},

And run my debuger with the breakpoint and finally just select my expresion and do click right > copy value.

A tar.gz is a tar file inside a gzip file, so 1st you must unzip the gzip file with gunzip -d filename.tar.gz , and then use tar to untar it. However, since gunzip says it isn't in gzip format, you can see what format it is in with file filename.tar.gz, and use the appropriate program to open it.

or

window.location.href = '/path'; //relative to domain

I'm on a roll, just found an even simpler way to do it using the by keyword in the hist method:

I have built semi-long shell scripts (300-500 lines) and Python code which does similar functionality. When many external commands are being executed, I find the shell is easier to use. Perl is also a good option when there is lots of text manipulation.

Extending other answers:

I found @GEverding's answer most flexible. It also works with aggregation:

test_db.js

print("name,email");

db.users.aggregate([
    { $match: {} }
]).forEach(function(user) {
        print(user.name+","+user.email);
    }
});

Execute the following command to export results:

mongo test_db < ./test_db.js >> ./test_db.csv

Unfortunately, it adds additional text to the CSV file which requires processing the file before we can use it:

MongoDB shell version: 3.2.10 
connecting to: test_db

But we can make mongo shell stop spitting out those comments and only print what we have asked for by passing the --quiet flag

mongo --quiet test_db < ./test_db.js >> ./test_db.csv

You can pass the format in to the ToString method, e.g.:

myFloatVariable.ToString("n2"); // 2dp Number

myFloatVariable.ToString("c2"); // 2dp currency

This error “Sub or Function not defined”, will come every time when there is some compile error in script, so please check syntax again of your script.

I guess that is why when you used msqbox instead of msgbox it throws the error.

Only suggestion is to access your resp_dict via .get() for a more graceful approach that will degrade well if the data isn't as expected.

resp_dict = json.loads(resp_str)
resp_dict.get('name') # will return None if 'name' doesn't exist

You could also add some logic to test for the key if you want as well.

if 'name' in resp_dict:
    resp_dict['name']
else:
    # do something else here.

For Jersey 2 you'd need to modify the code:

            .sslContext(ctx)
            .build();

In addition to what @berguiga-mohamed-amine stated, I just found that a wildcard requires leaving the module argument the empty string:

compile ("com.github.jsonld-java:jsonld-java:$jsonldJavaVersion") {
    exclude group: 'org.apache.httpcomponents', module: ''
    exclude group: 'org.slf4j', module: ''
}

Remember this if all your Strings in the column do not have an underscore (...or else if null value will be the output):

SELECT COALESCE
(SUBSTR("STRING_COLUMN" , 0, INSTR("STRING_COLUMN", '_')-1), 
"STRING_COLUMN") 
AS OUTPUT FROM DUAL

Python 2: You should use map and filter instead of list comprehensions.

An objective reason why you should prefer them even though they're not "Pythonic" is this:
They require functions/lambdas as arguments, which introduce a new scope.

I've gotten bitten by this more than once:

for x, y in somePoints:
    # (several lines of code here)
    squared = [x ** 2 for x in numbers]
    # Oops, x was silently overwritten!

but if instead I had said:

for x, y in somePoints:
    # (several lines of code here)
    squared = map(lambda x: x ** 2, numbers)

then everything would've been fine.

You could say I was being silly for using the same variable name in the same scope.

I wasn't. The code was fine originally -- the two xs weren't in the same scope.
It was only after I moved the inner block to a different section of the code that the problem came up (read: problem during maintenance, not development), and I didn't expect it.

Yes, if you never make this mistake then list comprehensions are more elegant.
But from personal experience (and from seeing others make the same mistake) I've seen it happen enough times that I think it's not worth the pain you have to go through when these bugs creep into your code.

Conclusion:

Use map and filter. They prevent subtle hard-to-diagnose scope-related bugs.

Side note:

Don't forget to consider using imap and ifilter (in itertools) if they are appropriate for your situation!

http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1230935955 states:

By default, the Arduino IDE and libraries does not use the operator new and operator delete. It does support malloc() and free(). So the solution is to implement new and delete operators for yourself, to use these functions.

Code:

#include <stdlib.h> // for malloc and free
void* operator new(size_t size) { return malloc(size); } 
void operator delete(void* ptr) { free(ptr); }

This let's you create objects, e.g.

C* c; // declare variable
c = new C(); // create instance of class C
c->M(); // call method M
delete(c); // free memory

While others have correctly suggested the use of array_multisort(), for some reason no answer seems to acknowledge the existence of array_column(), which can greatly simplify the solution. So my suggestion would be:

array_multisort(array_column($inventory, 'price'), SORT_DESC, $inventory);

Perhaps this is lame but you can also just point them both at some external object:

var cities = [];

function ParentCtrl() {
    var vm = this;
    vm.cities = cities;
    vm.cities[0] = 'Oakland';
}

function ChildCtrl($scope) {
    var vm = this;
    vm.cities = cities;
}

The benefit here is that edits in ChildCtrl now propogate back to the data in the parent.

This might work for you:

cat <<! | sed '/aaa=\(bbb\|ccc\|ddd\)/!s/\(aaa=\).*/\1xxx/'
> aaa=bbb
> aaa=ccc
> aaa=ddd
> aaa=[something else]
!
aaa=bbb
aaa=ccc
aaa=ddd
aaa=xxx

One option is to put the subquery in a LEFT JOIN:

select sum ( t.graduates ) - t1.summedGraduates 
from table as t
    left join 
     ( 
        select sum ( graduates ) summedGraduates, id
        from table  
        where group_code not in ('total', 'others' )
        group by id 
    ) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates 

Perhaps a better option would be to use SUM with CASE:

select sum(case when group_code = 'total' then graduates end) -
    sum(case when group_code not in ('total','others') then graduates end)
from yourtable

Just in case you need solution for Angular 2 then its simple, use property binding like below, e.g. you want to make input read only conditionally, then add in square braces the attrbute followed by = sign and expression.

<input [readonly]="mode=='VIEW'"> 

My solution is based on @Martijn Pieters' comment:

register_namespace only influences serialisation, not search.

So the trick here is to use different dictionaries for serialization and for searching.

namespaces = {
    '': 'http://www.example.com/default-schema',
    'spec': 'http://www.example.com/specialized-schema',
}

Now, register all namespaces for parsing and writing:

for name, value in namespaces.iteritems():
    ET.register_namespace(name, value)

For searching (find(), findall(), iterfind()) we need a non-empty prefix. Pass these functions a modified dictionary (here I modify the original dictionary, but this must be made only after the namespaces are registered).

self.namespaces['default'] = self.namespaces['']

Now, the functions from the find() family can be used with the default prefix:

print root.find('default:myelem', namespaces)

but

tree.write(destination)

does not use any prefixes for elements in the default namespace.

These all are ways:

String imageUri = "drawable://" + R.drawable.image;

Other ways I tested

Uri path = Uri.parse("android.resource://com.segf4ult.test/" + R.drawable.icon);
Uri otherPath = Uri.parse("android.resource://com.segf4ult.test/drawable/icon");

String path = path.toString();
String path = otherPath .toString();

Here's a simple function that you could use. Just plug n play.

This is Insert By Index, Not By Value.

you can choose to pass the array, or use one that you already have declared.

EDIT: Shorter Version:

   function insert($array, $index, $val)
   {
       $size = count($array); //because I am going to use this more than one time
       if (!is_int($index) || $index < 0 || $index > $size)
       {
           return -1;
       }
       else
       {
           $temp   = array_slice($array, 0, $index);
           $temp[] = $val;
           return array_merge($temp, array_slice($array, $index, $size));
       }
   }

  function insert($array, $index, $val) { //function decleration
    $temp = array(); // this temp array will hold the value 
    $size = count($array); //because I am going to use this more than one time
    // Validation -- validate if index value is proper (you can omit this part)       
        if (!is_int($index) || $index < 0 || $index > $size) {
            echo "Error: Wrong index at Insert. Index: " . $index . " Current Size: " . $size;
            echo "<br/>";
            return false;
        }    
    //here is the actual insertion code
    //slice part of the array from 0 to insertion index
    $temp = array_slice($array, 0, $index);//e.g index=5, then slice will result elements [0-4]
    //add the value at the end of the temp array// at the insertion index e.g 5
    array_push($temp, $val);
    //reconnect the remaining part of the array to the current temp
    $temp = array_merge($temp, array_slice($array, $index, $size)); 
    $array = $temp;//swap// no need for this if you pass the array cuz you can simply return $temp, but, if u r using a class array for example, this is useful. 

     return $array; // you can return $temp instead if you don't use class array
}

Now you can test the code using

//1
$result = insert(array(1,2,3,4,5),0, 0);
echo "<pre>";
echo "<br/>";
print_r($result);
echo "</pre>";
//2
$result = insert(array(1,2,3,4,5),2, "a");
echo "<pre>";
print_r($result);
echo "</pre>";
//3
$result = insert(array(1,2,3,4,5) ,4, "b");
echo "<pre>";
print_r($result);
echo "</pre>";
//4
$result = insert(array(1,2,3,4,5),5, 6);
echo "<pre>";
echo "<br/>";
print_r($result);
echo "</pre>";

And the result is :

//1
Array
(
    [0] => 0
    [1] => 1
    [2] => 2
    [3] => 3
    [4] => 4
    [5] => 5
)
//2
Array
(
    [0] => 1
    [1] => 2
    [2] => a
    [3] => 3
    [4] => 4
    [5] => 5
)
//3
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => b
    [5] => 5
)

//4
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
)

Here is how I remember when to use what -

Semaphore: Use a semaphore when you (thread) want to sleep till some other thread tells you to wake up. Semaphore 'down' happens in one thread (producer) and semaphore 'up' (for same semaphore) happens in another thread (consumer) e.g.: In producer-consumer problem, producer wants to sleep till at least one buffer slot is empty - only the consumer thread can tell when a buffer slot is empty.

Mutex: Use a mutex when you (thread) want to execute code that should not be executed by any other thread at the same time. Mutex 'down' happens in one thread and mutex 'up' must happen in the same thread later on. e.g.: If you are deleting a node from a global linked list, you do not want another thread to muck around with pointers while you are deleting the node. When you acquire a mutex and are busy deleting a node, if another thread tries to acquire the same mutex, it will be put to sleep till you release the mutex.

Spinlock: Use a spinlock when you really want to use a mutex but your thread is not allowed to sleep. e.g.: An interrupt handler within OS kernel must never sleep. If it does the system will freeze / crash. If you need to insert a node to globally shared linked list from the interrupt handler, acquire a spinlock - insert node - release spinlock.

Assuming a is a string. The Slice notation in python has the syntax -

list[<start>:<stop>:<step>]

So, when you do a[::-1], it starts from the end towards the first taking each element. So it reverses a. This is applicable for lists/tuples as well.

Example -

>>> a = '1234'
>>> a[::-1]
'4321'

Then you convert it to int and then back to string (Though not sure why you do that) , that just gives you back the string.

I recommend following the instructions in the Bootstrap 4 documentation:

Copy-paste the stylesheet <link> into your <head> before all other stylesheets to load our CSS.

Add our JavaScript plugins, jQuery, and Tether near the end of your pages, right before the closing tag. Be sure to place jQuery and Tether first, as our code depends on them. While we use jQuery’s slim build in our docs, the full version is also supported.

If you're using getline() after cin >> something, you need to flush the newline character out of the buffer in between. You can do it by using cin.ignore().

It would be something like this:

string messageVar;
cout << "Type your message: ";
cin.ignore(); 
getline(cin, messageVar);

This happens because the >> operator leaves a newline \n character in the input buffer. This may become a problem when you do unformatted input, like getline(), which reads input until a newline character is found. This happening, it will stop reading immediately, because of that \n that was left hanging there in your previous operation.

You must sort your data according your needs (es. in reverse order) and use select top query

    assert.Equal(t, nil, err)
    fmt.Println(string(b))

To receive arbitrary Json in Spring-Boot, you can simply use Jackson's JsonNode. The appropriate converter is automatically configured.

    @PostMapping(value="/process")
    public void process(@RequestBody com.fasterxml.jackson.databind.JsonNode payload) {
        System.out.println(payload);
    }

If a variable is defined as public static it can be accessed via its class name from any class.

Usually functions are defined as public static which can be accessed just by calling the implementing class name.

A very good example of it is the sleep() method in Thread class

Thread.sleep(2500);

If a variable is defined as private static it can be accessed only within that class so no class name is needed or you can still use the class name (upto you). The difference between private var_name and private static var_name is that private static variables can be accessed only by static methods of the class while private variables can be accessed by any method of that class(except static methods)

A very good example of it is while defining database connections or constants which require declaring variable as private static .

Another common example is

private static int numberOfCars=10;

public static int returnNumber(){

return numberOfCars;

}

Your query should look like

UPDATE table_name

• px - one pixel, same as to what is used in CSS, JavaScript, etc.
• sp - scale-independent pixels

Normally sp is used for font sizes, while dip is used (also called dp) for others.

Here is example how to remove NULL characters using ex (in-place):

ex -s +"%s/\%x00//g" -cwq nulls.txt

and for multiple files:

ex -s +'bufdo!%s/\%x00//g' -cxa *.txt

^{For recursivity, you may use globbing option **/*.txt (if it is supported by your shell).}

You should work with padding on the inner container rather than with margin. Try this!

HTML

<div class="row info-panel">
    <div class="col-md-4" id="server_1">
       <div class="server-action-menu">
           Server 1
       </div>
   </div>
</div>

CSS

.server-action-menu {
    background-color: transparent;
    background-image: linear-gradient(to bottom, rgba(30, 87, 153, 0.2) 0%, rgba(125, 185, 232, 0) 100%);
    background-repeat: repeat;
    border-radius:10px;
    padding: 5px;
}

In addition to Richard Simões answer you can also use the Page Visibility API.

if (!document.hidden) {
    // do what you need
}

This specification defines a means for site developers to programmatically determine the current visibility state of the page in order to develop power and CPU efficient web applications.

Learn more (2019 update)

• All modern browsers are supporting document.hidden
• http://davidwalsh.name/page-visibility
• https://developers.google.com/chrome/whitepapers/pagevisibility
• Example pausing a video when window/tab is hidden
  https://web.archive.org/web/20170609212707/http://www.samdutton.com/pageVisibility/

Set CSS display property to none.

document.getElementById("test").style.display = "none";

Also, you do not need javascript: for the onclick attribute.

<input type="image" src="../images/btnFind.png" id="find" name="find" 
    onclick="hide();" />

Finally, make sure you do not have multiple elements with the same ID.

If your form goes nowhere, Phil suggested that you should prevent submission of the form. Simply return false in the onsubmit handler.

<form method="post" id="test" onsubmit="return false;">

If you want the form to post, but hide the div on subsequent page load, you will have to use server-side code to hide the element:

<script type="text/javascript">
function hide() {
    document.getElementById("test").style.display = "none";
}
window.onload = function() {
    // if form was submitted, PHP will print the below, 
    //    which runs function hide() on page load
    <?= ($_POST['ampid'] != '') ? 'hide();' : '' ?>
}
</script>

C++11 update to a very old question: Print variable type in C++.

The accepted (and good) answer is to use typeid(a).name(), where a is a variable name.

Now in C++11 we have decltype(x), which can turn an expression into a type. And decltype() comes with its own set of very interesting rules. For example decltype(a) and decltype((a)) will generally be different types (and for good and understandable reasons once those reasons are exposed).

Will our trusty typeid(a).name() help us explore this brave new world?

No.

But the tool that will is not that complicated. And it is that tool which I am using as an answer to this question. I will compare and contrast this new tool to typeid(a).name(). And this new tool is actually built on top of typeid(a).name().

The fundamental issue:

typeid(a).name()

throws away cv-qualifiers, references, and lvalue/rvalue-ness. For example:

const int ci = 0;
std::cout << typeid(ci).name() << '\n';

For me outputs:

i

and I'm guessing on MSVC outputs:

int

I.e. the const is gone. This is not a QOI (Quality Of Implementation) issue. The standard mandates this behavior.

What I'm recommending below is:

template <typename T> std::string type_name();

which would be used like this:

const int ci = 0;
std::cout << type_name<decltype(ci)>() << '\n';

and for me outputs:

int const

<disclaimer> I have not tested this on MSVC. </disclaimer> But I welcome feedback from those who do.

The C++11 Solution

I am using __cxa_demangle for non-MSVC platforms as recommend by ipapadop in his answer to demangle types. But on MSVC I'm trusting typeid to demangle names (untested). And this core is wrapped around some simple testing that detects, restores and reports cv-qualifiers and references to the input type.

#include <type_traits>
#include <typeinfo>
#ifndef _MSC_VER
#   include <cxxabi.h>
#endif
#include <memory>
#include <string>
#include <cstdlib>

template <class T>
std::string
type_name()
{
    typedef typename std::remove_reference<T>::type TR;
    std::unique_ptr<char, void(*)(void*)> own
           (
#ifndef _MSC_VER
                abi::__cxa_demangle(typeid(TR).name(), nullptr,
                                           nullptr, nullptr),
#else
                nullptr,
#endif
                std::free
           );
    std::string r = own != nullptr ? own.get() : typeid(TR).name();
    if (std::is_const<TR>::value)
        r += " const";
    if (std::is_volatile<TR>::value)
        r += " volatile";
    if (std::is_lvalue_reference<T>::value)
        r += "&";
    else if (std::is_rvalue_reference<T>::value)
        r += "&&";
    return r;
}

The Results

With this solution I can do this:

int& foo_lref();
int&& foo_rref();
int foo_value();

int
main()
{
    int i = 0;
    const int ci = 0;
    std::cout << "decltype(i) is " << type_name<decltype(i)>() << '\n';
    std::cout << "decltype((i)) is " << type_name<decltype((i))>() << '\n';
    std::cout << "decltype(ci) is " << type_name<decltype(ci)>() << '\n';
    std::cout << "decltype((ci)) is " << type_name<decltype((ci))>() << '\n';
    std::cout << "decltype(static_cast<int&>(i)) is " << type_name<decltype(static_cast<int&>(i))>() << '\n';
    std::cout << "decltype(static_cast<int&&>(i)) is " << type_name<decltype(static_cast<int&&>(i))>() << '\n';
    std::cout << "decltype(static_cast<int>(i)) is " << type_name<decltype(static_cast<int>(i))>() << '\n';
    std::cout << "decltype(foo_lref()) is " << type_name<decltype(foo_lref())>() << '\n';
    std::cout << "decltype(foo_rref()) is " << type_name<decltype(foo_rref())>() << '\n';
    std::cout << "decltype(foo_value()) is " << type_name<decltype(foo_value())>() << '\n';
}

and the output is:

decltype(i) is int
decltype((i)) is int&
decltype(ci) is int const
decltype((ci)) is int const&
decltype(static_cast<int&>(i)) is int&
decltype(static_cast<int&&>(i)) is int&&
decltype(static_cast<int>(i)) is int
decltype(foo_lref()) is int&
decltype(foo_rref()) is int&&
decltype(foo_value()) is int

Note (for example) the difference between decltype(i) and decltype((i)). The former is the type of the declaration of i. The latter is the "type" of the expression i. (expressions never have reference type, but as a convention decltype represents lvalue expressions with lvalue references).

Thus this tool is an excellent vehicle just to learn about decltype, in addition to exploring and debugging your own code.

In contrast, if I were to build this just on typeid(a).name(), without adding back lost cv-qualifiers or references, the output would be:

decltype(i) is int
decltype((i)) is int
decltype(ci) is int
decltype((ci)) is int
decltype(static_cast<int&>(i)) is int
decltype(static_cast<int&&>(i)) is int
decltype(static_cast<int>(i)) is int
decltype(foo_lref()) is int
decltype(foo_rref()) is int
decltype(foo_value()) is int

I.e. Every reference and cv-qualifier is stripped off.

C++14 Update

Just when you think you've got a solution to a problem nailed, someone always comes out of nowhere and shows you a much better way. :-)

This answer from Jamboree shows how to get the type name in C++14 at compile time. It is a brilliant solution for a couple reasons:

1. It's at compile time!
2. You get the compiler itself to do the job instead of a library (even a std::lib). This means more accurate results for the latest language features (like lambdas).

Jamboree's answer doesn't quite lay everything out for VS, and I'm tweaking his code a little bit. But since this answer gets a lot of views, take some time to go over there and upvote his answer, without which, this update would never have happened.

This code will auto-backoff on the constexpr if you're still stuck in ancient C++11. And if you're painting on the cave wall with C++98/03, the noexcept is sacrificed as well.

I've updated the constants for VS thanks to the very nice detective work by Jive Dadson in the comments below.

Update:

Be sure to check out this rewrite below which eliminates the unreadable magic numbers in my latest formulation.

The following script works for me for multiple values of $COLUMNS. I wonder if you are not setting COLUMNS prior to this call?

#!/bin/bash
COLUMNS=30
svn diff $@ --diff-cmd /usr/bin/diff -x "-y -w -p -W $COLUMNS"

Can you echo $COLUMNS inside your script to see if it set correctly?

Adding to corroded answer from the same referenced page is a PowerShell version http://blogs.msdn.com/b/oldnewthing/archive/2008/04/17/8399914.aspx#8408736

Get-ChildItem -Recurse . | where { $_.PSISContainer -and @( $_ | Get-ChildItem ).Count -eq 0 } | Remove-Item

or, more tersely,

gci -R . | where { $_.PSISContainer -and @( $_ | gci ).Count -eq 0 } | ri

Use a for loop instead of .forEach()

var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false

for(var call of myObj) {
    console.log(call)
    
    var a = call['a'], b = call['b']
     
    if(a == null || b == null) {
        result = false
        break
    }
}

You also can use ng-attr-src="{{variable}}" instead of src="{{variable}}" and the attribute will only be generated once the compiler compiled the templates. This is mentioned here in the documentation: https://docs.angularjs.org/guide/directive#-ngattr-attribute-bindings

I've written my own implementation. Not sure if it counts as a better solution:

/*
    a function for deep cloning objects that contains other nested objects and circular structures.
    objects are stored in a 3D array, according to their length (number of properties) and their depth in the original object.
                                    index (z)
                                         |
                                         |
                                         |
                                         |
                                         |
                                         |                      depth (x)
                                         |_ _ _ _ _ _ _ _ _ _ _ _
                                        /_/_/_/_/_/_/_/_/_/
                                       /_/_/_/_/_/_/_/_/_/
                                      /_/_/_/_/_/_/...../
                                     /................./
                                    /.....            /
                                   /                 /
                                  /------------------
            object length (y)    /
*/

Following is the implementation:

function deepClone(obj) {
    var depth = -1;
    var arr = [];
    return clone(obj, arr, depth);
}

/**
 *
 * @param obj source object
 * @param arr 3D array to store the references to objects
 * @param depth depth of the current object relative to the passed 'obj'
 * @returns {*}
 */
function clone(obj, arr, depth){
    if (typeof obj !== "object") {
        return obj;
    }

    var length = Object.keys(obj).length; // native method to get the number of properties in 'obj'

    var result = Object.create(Object.getPrototypeOf(obj)); // inherit the prototype of the original object
    if(result instanceof Array){
        result.length = length;
    }

    depth++; // depth is increased because we entered an object here

    arr[depth] = []; // this is the x-axis, each index here is the depth
    arr[depth][length] = []; // this is the y-axis, each index is the length of the object (aka number of props)
    // start the depth at current and go down, cyclic structures won't form on depths more than the current one
    for(var x = depth; x >= 0; x--){
        // loop only if the array at this depth and length already have elements
        if(arr[x][length]){
            for(var index = 0; index < arr[x][length].length; index++){
                if(obj === arr[x][length][index]){
                    return obj;
                }
            }
        }
    }

    arr[depth][length].push(obj); // store the object in the array at the current depth and length
    for (var prop in obj) {
        if (obj.hasOwnProperty(prop)) result[prop] = clone(obj[prop], arr, depth);
    }

    return result;
}

Note that apart from rows and columns there is a number of channels and type. When it is clear what type is, the channels can act as an extra dimension as in CV_8UC3 so you would address a matrix as

uchar a = M.at<Vec3b>(y, x)[i];

So the size in terms of elements of elementary type is M.rows * M.cols * M.cn

To find the max element one can use

Mat src;
double minVal, maxVal;
minMaxLoc(src, &minVal, &maxVal);

Try this:

$NameRegex = "chalmw-dm"  
$NameR = "$($NameRegex)*"
Get-ADComputer -Filter {name -like $NameR -and Enabled -eq $True}

There has been some considerable confusion over space reclamation in MongoDB, and some recommended practice are downright dangerous to do in certain deployment types. More details below:

TL;DR repairDatabase attempts to salvage data from a standalone MongoDB deployments that is trying to recover from a disk corruption. If it recovers space, it is purely a side effect. Recovering space should never be the primary consideration of running repairDatabase.

Recover space in a standalone node

WiredTiger: For a standalone node with WiredTiger, running compact will release space to the OS, with one caveat: The compact command on WiredTiger on MongoDB 3.0.x was affected by this bug: SERVER-21833 which was fixed in MongoDB 3.2.3. Prior to this version, compact on WiredTiger could silently fail.

MMAPv1: Due to the way MMAPv1 works, there is no safe and supported method to recover space using the MMAPv1 storage engine. compact in MMAPv1 will defragment the data files, potentially making more space available for new documents, but it will not release space back to the OS.

You may be able to run repairDatabase if you fully understand the consequences of this potentially dangerous command (see below), since repairDatabase essentially rewrites the whole database by discarding corrupt documents. As a side effect, this will create new MMAPv1 data files without any fragmentation on it and release space back to the OS.

For a less adventurous method, running mongodump and mongorestore may be possible as well in an MMAPv1 deployment, subject to the size of your deployment.

Recover space in a replica set

For replica set configurations, the best and the safest method to recover space is to perform an initial sync, for both WiredTiger and MMAPv1.

If you need to recover space from all nodes in the set, you can perform a rolling initial sync. That is, perform initial sync on each of the secondaries, before finally stepping down the primary and perform initial sync on it. Rolling initial sync method is the safest method to perform replica set maintenance, and it also involves no downtime as a bonus.

Please note that the feasibility of doing a rolling initial sync also depends on the size of your deployment. For extremely large deployments, it may not be feasible to do an initial sync, and thus your options are somewhat more limited. If WiredTiger is used, you may be able to take one secondary out of the set, start it as a standalone, run compact on it, and rejoin it to the set.

Regarding repairDatabase

Please don't run repairDatabase on replica set nodes. This is very dangerous, as mentioned in the repairDatabase page and described in more details below.

The name repairDatabase is a bit misleading, since the command doesn't attempt to repair anything. The command was intended to be used when there's disk corruption on a standalone node, which could lead to corrupt documents.

The repairDatabase command could be more accurately described as "salvage database". That is, it recreates the databases by discarding corrupt documents in an attempt to get the database into a state where you can start it and salvage intact document from it.

In MMAPv1 deployments, this rebuilding of the database files releases space to the OS as a side effect. Releasing space to the OS was never the purpose.

Consequences of repairDatabase on a replica set

In a replica set, MongoDB expects all nodes in the set to contain identical data. If you run repairDatabase on a replica set node, there is a chance that the node contains undetected corruption, and repairDatabase will dutifully remove the corrupt documents for you.

Predictably, this makes that node contains a different dataset from the rest of the set. If an update happens to hit that single document, the whole set could crash.

To make matters worse, it is entirely possible that this situation could stay dormant for a long time, only to strike suddenly with no apparent reason.

Like this.

SELECT DISTINCT COL_NAME FROM myTable WHERE COL_NAME iLIKE '%Priceorder%'

In postgresql.

Its not possible as you are expecting. But you can do something like this. Pass the your java script value to the servlet/controller, do your processing and then pass this value to the jsp page by putting it into some object's as your requirement. Then you can use this value as you want.

Find: value="([\d]+|[\d])"

Replace: \1

It will really return you

4
403
200
201
116
15

js:

a='value="4"\nvalue="403"\nvalue="200"\nvalue="201"\nvalue="116"\nvalue="15"';
a = a.replace(/value="([\d]+|[\d])"/g, '$1');
console.log(a);

Response.write() don't give formatted output. The latter one allows you to write formatted output.

Response.write - it writes the text stream Response.output.write - it writes the HTTP Output Stream.

$id = $access_data['Privilege']['id']; 

if(!in_array($id,$user_access_arr));
    $user_access_arr[] = $id;
    $this->Session->setFlash(__('Access Denied! You are not eligible to access this.'), 'flash_custom_success');
    return $this->redirect(array('controller'=>'Dashboard','action'=>'index'));

It's actually fairly easy, just enter it as a latitude,longitude pair, ie 46.38S,115.36E (which is in the middle of the ocean). You'll want to convert it to decimal though (divide the minutes portion by 60 and add it to the degrees [I've done that with your example]).

This method works for me very well.

    // Recursive method to recover files and folders and to print the information
public static void listFiles(String directoryName) {

    File file = new File(directoryName);
    File[] fileList = file.listFiles(); // List files inside the main dir
    int j;
    String extension;
    String fileName;

    if (fileList != null) {
        for (int i = 0; i < fileList.length; i++) {
            extension = "";
            if (fileList[i].isFile()) {
                fileName = fileList[i].getName();

                if (fileName.lastIndexOf(".") != -1 && fileName.lastIndexOf(".") != 0) {
                    extension = fileName.substring(fileName.lastIndexOf(".") + 1);
                    System.out.println("THE " + fileName + "  has the extension =   " + extension);
                } else {
                    extension = "Unknown";
                    System.out.println("extension2 =    " + extension);
                }

                filesCount++;
                allStats.add(new FilePropBean(filesCount, fileList[i].getName(), fileList[i].length(), extension,
                        fileList[i].getParent()));
            } else if (fileList[i].isDirectory()) {
                filesCount++;
                extension = "";
                allStats.add(new FilePropBean(filesCount, fileList[i].getName(), fileList[i].length(), extension,
                        fileList[i].getParent()));
                listFiles(String.valueOf(fileList[i]));
            }
        }
    }
}

Here is working solution:

Output:

public class XmlTest {

    private static final Logger log = LoggerFactory.getLogger(XmlTest.class);

    @Test
    public void createDefaultBook() throws JAXBException {
        JAXBContext jaxbContext = JAXBContext.newInstance(Book.class);
        Marshaller marshaller = jaxbContext.createMarshaller();

        StringWriter writer = new StringWriter();
        marshaller.marshal(new Book(), writer);

        log.debug("Book xml:\n {}", writer.toString());
    }


    @XmlAccessorType(XmlAccessType.FIELD)
    @XmlRootElement(name = "book")
    public static class Book {

        @XmlElementRef(name = "price")
        private Price price = new Price();


    }

    @XmlAccessorType(XmlAccessType.FIELD)
    @XmlRootElement(name = "price")
    public static class Price {
        @XmlAttribute(name = "drawable")
        private Boolean drawable = true; //you may want to set default value here

        @XmlValue
        private int priceValue = 1234;

        public Boolean getDrawable() {
            return drawable;
        }

            this.drawable = drawable;
        }

        public int getPriceValue() {
            return priceValue;
        }

        public void setPriceValue(int priceValue) {
            this.priceValue = priceValue;
        }
    }
}

Output:

remove href attribute:

<a id="" onclick="f1()">jhhghj</a>

if link styles are important then:

<a href="javascript:void(f1())">jhhghj</a>

I made a Method to do this

    string test = "Paul";
    test = ReplaceAtIndex(0, 'M', test);

    (...)

    static string ReplaceAtIndex(int i, char value, string word)
    {
        char[] letters = word.ToCharArray();
        letters[i] = value;
        return string.Join("", letters);
    }

To start with, from the Oracle Database Data Warehousing Guide:

Restrictions on Fast Refresh on Materialized Views with Joins Only

...

• Rowids of all the tables in the FROM list must appear in the SELECT list of the query.

This means that your statement will need to look something like this:

CREATE MATERIALIZED VIEW MV_Test
  NOLOGGING
  CACHE
  BUILD IMMEDIATE 
  REFRESH FAST ON COMMIT 
  AS
    SELECT V.*, P.*, V.ROWID as V_ROWID, P.ROWID as P_ROWID 
    FROM TPM_PROJECTVERSION V,
         TPM_PROJECT P 
    WHERE P.PROJECTID = V.PROJECTID

Another key aspect to note is that your materialized view logs must be created as with rowid.

Below is a functional test scenario:

CREATE TABLE foo(foo NUMBER, CONSTRAINT foo_pk PRIMARY KEY(foo));

CREATE MATERIALIZED VIEW LOG ON foo WITH ROWID;

CREATE TABLE bar(foo NUMBER, bar NUMBER, CONSTRAINT bar_pk PRIMARY KEY(foo, bar));

CREATE MATERIALIZED VIEW LOG ON bar WITH ROWID;

CREATE MATERIALIZED VIEW foo_bar
  NOLOGGING
  CACHE
  BUILD IMMEDIATE
  REFRESH FAST ON COMMIT  AS SELECT foo.foo, 
                                    bar.bar, 
                                    foo.ROWID AS foo_rowid, 
                                    bar.ROWID AS bar_rowid 
                               FROM foo, bar
                              WHERE foo.foo = bar.foo;

Is this a solution?

class Foo
{
public:
    size_t count;
    Foo()
    {
        static size_t count = 0;
        this->count = count += 1;
    }
};

shutil.copy and shutil.copy2 are copying files.

shutil.copytree copies a folder with all the files and all subfolders. shutil.copytree is using shutil.copy2 to copy the files.

So the analog to cp -r you are saying is the shutil.copytree because cp -r targets and copies a folder and its files/subfolders like shutil.copytree. Without the -r cp copies files like shutil.copy and shutil.copy2 do.

In .NET Core WebAPI (version 3.0 and above):

var requestUrl = $"{Request.Scheme}://{Request.Host.Value}/";


     

You can create a boolean field and check it inside run:

public class Task implements Runnable {

   private volatile boolean isRunning = true;

   public void run() {

     while (isRunning) {
         //do work
     }
   }

   public void kill() {
       isRunning = false;
   }

}

To stop it just call

task.kill();

This should work.

Even simpler:

$('#selectBox option')[3].selected = true;

Try this small solution:

$("#some_id").attr("checked") ? 1 : 0;

or

$("#some_id").attr("checked") || 0;

You can use Exif-JS , to check the "Orientation" property of the image. Then apply a css transform as needed.

EXIF.getData(imageElement, function() {
                var orientation = EXIF.getTag(this, "Orientation");

                if(orientation == 6)
                    $(imageElement).css('transform', 'rotate(90deg)')
});  

I ran into this problem today actually playing with the v22 library.

Assuming that you're using styles you can set the colorButtonNormal property and the buttons will use that color by default.

<style name="AppTheme" parent="BaseTheme">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/primaryColor</item>
    <item name="colorPrimaryDark">@color/primaryColorDark</item>
    <item name="colorAccent">@color/accentColor</item>
    <item name="colorButtonNormal">@color/primaryColor</item>
</style>

Outside of that you could still make a style for the button then use that per button if you needed an assortment of colors (haven't tested, just speculating).

Remember to add android: before the item names in your v21 style.

textField_in = new JTextField();
textField_in.addKeyListener(new KeyAdapter() {

    @Override
    public void keyPressed(KeyEvent arg0) {
        System.out.println(arg0.getExtendedKeyCode());
        if (arg0.getKeyCode()==10) {
            String name = textField_in.getText();
            textField_out.setText(name);
        }

    }

});
textField_in.setBounds(173, 40, 86, 20);
frame.getContentPane().add(textField_in);
textField_in.setColumns(10);

I was facing the same issue after upgrading my java version.I had more than one jdk installation. I have manually uninstalled the old jdk version . Then it worked for me.

The DESCRIBE command is your friend. You can describe one keyspace, list keyspaces, one table or list all tables in keyspace, the cluster and much more. You can get the full idea by typing

HELP DESCRIBE in cqlsh.

Connected to mscluster at 127.0.0.1:9042. [cqlsh 5.0.1 | Cassandra 3.8 | CQL spec 3.4.2 | Native protocol v4] Use HELP for help.

cqlsh> HELP DESCRIBE

    DESCRIBE [cqlsh only]

    (DESC may be used as a shorthand.)

      Outputs information about the connected Cassandra cluster, or about
      the data objects stored in the cluster. Use in one of the following ways:...<omitted for brevity>

• DESCRIBE <your key space name> - describes the command used to create keyspace

cqlsh> DESCRIBE testkeyspace;

CREATE KEYSPACE testkeyspace WITH replication = {'class':'SimpleStrategy', 'replication_factor': '3'} AND durable_writes = true;

• DESCRIBE keyspaces - lists all keyspaces

cqlsh> DESCRIBE KEYSPACES

I used the following command to copy my extensions from Visual Studio Code to Visual Studio Code insiders:

code --list-extensions | xargs -L 1 code-insiders --install-extension

The argument -L 1 allows us to execute the command code-insiders --install-extension once for each input line generated by code --list-extensions.

If you are using Sqlserver 2005 or above, using REVERSE function many times is detrimental to performance, below code is more efficient.

DECLARE @FilePath VARCHAR(50) = 'My\Super\Long\String\With\Long\Words'
DECLARE @FindChar VARCHAR(1) = '\'

-- Shows text before last slash
SELECT LEFT(@FilePath, LEN(@FilePath) - CHARINDEX(@FindChar,REVERSE(@FilePath))) AS Before
-- Shows text after last slash
SELECT RIGHT(@FilePath, CHARINDEX(@FindChar,REVERSE(@FilePath))-1) AS After
-- Shows the position of the last slash
SELECT LEN(@FilePath) - CHARINDEX(@FindChar,REVERSE(@FilePath)) AS LastOccuredAt

A more up to date solution, for encoding:

// This is the same for all of the below, and
// you probably won't need it except for debugging
// in most cases.
function bytesToHex(bytes) {
  return Array.from(
    bytes,
    byte => byte.toString(16).padStart(2, "0")
  ).join("");
}

// You almost certainly want UTF-8, which is
// now natively supported:
function stringToUTF8Bytes(string) {
  return new TextEncoder().encode(string);
}

// But you might want UTF-16 for some reason.
// .charCodeAt(index) will return the underlying
// UTF-16 code-units (not code-points!), so you
// just need to format them in whichever endian order you want.
function stringToUTF16Bytes(string, littleEndian) {
  const bytes = new Uint8Array(string.length * 2);
  // Using DataView is the only way to get a specific
  // endianness.
  const view = new DataView(bytes.buffer);
  for (let i = 0; i != string.length; i++) {
    view.setUint16(i, string.charCodeAt(i), littleEndian);
  }
  return bytes;
}

// And you might want UTF-32 in even weirder cases.
// Fortunately, iterating a string gives the code
// points, which are identical to the UTF-32 encoding,
// though you still have the endianess issue.
function stringToUTF32Bytes(string, littleEndian) {
  const codepoints = Array.from(string, c => c.codePointAt(0));
  const bytes = new Uint8Array(codepoints.length * 4);
  // Using DataView is the only way to get a specific
  // endianness.
  const view = new DataView(bytes.buffer);
  for (let i = 0; i != codepoints.length; i++) {
    view.setUint32(i, codepoints[i], littleEndian);
  }
  return bytes;
}

Examples:

bytesToHex(stringToUTF8Bytes("hello ?? "))
// "68656c6c6f20e6bca2e5ad9720f09f918d"
bytesToHex(stringToUTF16Bytes("hello ?? ", false))
// "00680065006c006c006f00206f225b570020d83ddc4d"
bytesToHex(stringToUTF16Bytes("hello ?? ", true))
// "680065006c006c006f002000226f575b20003dd84ddc"
bytesToHex(stringToUTF32Bytes("hello ?? ", false))
// "00000068000000650000006c0000006c0000006f0000002000006f2200005b57000000200001f44d"
bytesToHex(stringToUTF32Bytes("hello ?? ", true))
// "68000000650000006c0000006c0000006f00000020000000226f0000575b0000200000004df40100"

For decoding, it's generally a lot simpler, you just need:

function hexToBytes(hex) {
    const bytes = new Uint8Array(hex.length / 2);
    for (let i = 0; i !== bytes.length; i++) {
        bytes[i] = parseInt(hex.substr(i * 2, 2), 16);
    }
    return bytes;
}

then use the encoding parameter of TextDecoder:

// UTF-8 is default
new TextDecoder().decode(hexToBytes("68656c6c6f20e6bca2e5ad9720f09f918d"));
// but you can also use:
new TextDecoder("UTF-16LE").decode(hexToBytes("680065006c006c006f002000226f575b20003dd84ddc"))
new TextDecoder("UTF-16BE").decode(hexToBytes("00680065006c006c006f00206f225b570020d83ddc4d"));
// "hello ?? "

Here's the list of allowed encoding names: https://www.w3.org/TR/encoding/#names-and-labels

You might notice UTF-32 is not on that list, which is a pain, so:

function bytesToStringUTF32(bytes, littleEndian) {
  const view = new DataView(bytes.buffer);
  const codepoints = new Uint32Array(view.byteLength / 4);
  for (let i = 0; i !== codepoints.length; i++) {
    codepoints[i] = view.getUint32(i * 4, littleEndian);
  }
  return String.fromCodePoint(...codepoints);
}

Then:

bytesToStringUTF32(hexToBytes("00000068000000650000006c0000006c0000006f0000002000006f2200005b57000000200001f44d"), false)
bytesToStringUTF32(hexToBytes("68000000650000006c0000006c0000006f00000020000000226f0000575b0000200000004df40100"), true)
// "hello ?? "

If you want to manipulate the actual CSS class instead of modifying the DOM elements or using modifier CSS classes, see https://stackoverflow.com/a/50036923/482916.

Problem with ImageIO.read is that it is really slow. All you need to do is to read image header to get the size. ImageIO.getImageReader is perfect candidate.

Here is the Groovy example, but the same thing applies to Java

def stream = ImageIO.createImageInputStream(newByteArrayInputStream(inputStream))
def formatReader = ImageIO.getImageWritersByFormatName(format).next() 
def reader = ImageIO.getImageReader(formatReader)
reader.setInput(stream, true)

println "width:reader.getWidth(0) -> height: reader.getHeight(0)"

The performance was the same as using SimpleImageInfo java library.

https://github.com/cbeust/personal/blob/master/src/main/java/com/beust/SimpleImageInfo.java

For example,

package main

import (
    "flag"
    "fmt"
    "os"
    "strconv"
)

func main() {
    flag.Parse()
    s := flag.Arg(0)
    // string to int
    i, err := strconv.Atoi(s)
    if err != nil {
        // handle error
        fmt.Println(err)
        os.Exit(2)
    }
    fmt.Println(s, i)
}

When a thread is executing and you want to execute the main UI thread which is blocked by current thread, then use the below:

current thread:

Dispatcher.CurrentDispatcher.Invoke(MethodName,
    new object[] { parameter1, parameter2 }); // if passing 2 parameters to method.

Main UI thread:

Application.Current.Dispatcher.BeginInvoke(
    DispatcherPriority.Background, new Action(() => MethodName(parameter)));

I recommend using the awesome requests library:

import requests

url = 'http://maps.googleapis.com/maps/api/directions/json'

params = dict(
    origin='Chicago,IL',
    destination='Los+Angeles,CA',
    waypoints='Joplin,MO|Oklahoma+City,OK',
    sensor='false'
)

resp = requests.get(url=url, params=params)
data = resp.json() # Check the JSON Response Content documentation below

JSON Response Content: https://requests.readthedocs.io/en/master/user/quickstart/#json-response-content

Simple Soltion

UPDATE `table_name`
 SET `field_name` = replace(same_field_name, 'unwanted_text', 'wanted_text')

If you get the object after creation (for instance after "seasonal_decompose"), you can always access and edit the properties of the plot; for instance, changing the color of the first subplot from blue to black:

plt.axes[0].get_lines()[0].set_color('black')

You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

Each ng-repeat creates a child scope with the passed data, and also adds an additional $index variable in that scope.

So what you need to do is reach up to the parent scope, and use that $index.

See http://plnkr.co/edit/FvVhirpoOF8TYnIVygE6?p=preview

<li class="tutorial_title {{tutorial.active}}" ng-click="loadFromMenu($parent.$index)" ng-repeat="tutorial in section.tutorials">
    {{tutorial.name}}
</li>

If you are truly dynamically setting this, you should set the .Url field of instance of the proxy class you are calling.

Setting the value in the .config file from within your program:

1. Is a mess;

2. Might not be read until the next application start.

If it is only something that needs to be done once per installation, I'd agree with the other posters and use the .config file and the dynamic setting.

Say you want to fill with number 13.

int[] myarr = Enumerable.Range(0, 10).Select(n => 13).ToArray();

or

List<int> myarr = Enumerable.Range(0,10).Select(n => 13).ToList();

if you prefer a list.

The SELECT ... INTO needs to be in the select from the CTE.

;WITH Calendar
     AS (SELECT /*... Rest of CTE definition removed for clarity*/)
SELECT EventID,
       EventStartDate,
       EventEndDate,
       PlannedDate                   AS [EventDates],
       Cast(PlannedDate AS DATETIME) AS DT,
       Cast(EventStartTime AS TIME)  AS ST,
       Cast(EventEndTime AS TIME)    AS ET,
       EventTitle,
       EventType
INTO TEMPBLOCKEDDATES /* <---- INTO goes here*/        
FROM   Calendar
WHERE  ( PlannedDate >= Getdate() )
       AND ',' + EventEnumDays + ',' LIKE '%,' + Cast(Datepart(dw, PlannedDate) AS CHAR(1)) + ',%'
        OR EventEnumDays IS NULL
ORDER  BY EventID,
          PlannedDate
OPTION (maxrecursion 0) 

You need to set a height on the DIV. Otherwise it will keep expanding indefinitely.

Open up a command terminal (CTRL+ALT+T) and try running this command:

anaconda-navigator

When I installed Anaconda, and read the website docs, they said that they tend to not add a file or menu path to run the navigator because there are so many different versions of different systems, instead they give the above terminal command to start the navigator GUI and advise on setting up a shortcut to do this process manually - if that works for you it shouldn't be too much trouble to do it this way - I do it like this personally

The startup project that references the project where Entity Framework is being used needs the following two assemblies in it's bin folder:

• EntityFramework.dll
• EntityFramework.SqlServer.dll

Adding a <section> to the <configSections> of the .config file on the startup project makes the first assembly available in that bin directory. You can copy this from the .config file of your Entity Framework project:

<configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>

To make the second .dll available in the bin folder, although not practical, a manual copy from the bin folder of the Entity Framework project can be made. A better alternative is to add to the Post-Build Events of the Entity Framework project the following lines, which will automate the process:

cd $(ProjectDir)
xcopy /y bin\Debug\EntityFramework.SqlServer.dll ..\{PATH_TO_THE_PROJECT_THAT_NEEDS_THE_DLL}\bin\Debug\

In Alamofire 4 it is important to add the body data before you add the file data!

let parameters = [String: String]()
[...]
self.manager.upload(
    multipartFormData: { multipartFormData in
        for (key, value) in parameters {
            multipartFormData.append(value.data(using: .utf8)!, withName: key)
        }
        multipartFormData.append(imageData, withName: "user", fileName: "user.jpg", mimeType: "image/jpeg")
    },
    to: path,
    [...]
)

This worked for me :

ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),R.layout.simple_spinner_item,areas);
            Spinner areasSpinner = (Spinner) view.findViewById(R.id.area_spinner);
            areasSpinner.setAdapter(adapter);

and in my layout folder I created simple_spinner_item:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
// add custom fields here 
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:paddingStart="?android:attr/listPreferredItemPaddingStart"
android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:paddingLeft="?android:attr/listPreferredItemPaddingLeft"
android:paddingRight="?android:attr/listPreferredItemPaddingRight" />

function dec2bin(dec){
    return (dec >>> 0).toString(2);
}

dec2bin(1);    // 1
dec2bin(-1);   // 11111111111111111111111111111111
dec2bin(256);  // 100000000
dec2bin(-256); // 11111111111111111111111100000000

You can use Number.toString(2) function, but it has some problems when representing negative numbers. For example, (-1).toString(2) output is "-1".

To fix this issue, you can use the unsigned right shift bitwise operator (>>>) to coerce your number to an unsigned integer.

If you run (-1 >>> 0).toString(2) you will shift your number 0 bits to the right, which doesn't change the number itself but it will be represented as an unsigned integer. The code above will output "11111111111111111111111111111111" correctly.

This question has further explanation.

-3 >>> 0 (right logical shift) coerces its arguments to unsigned integers, which is why you get the 32-bit two's complement representation of -3.

If each item in the list is a string (and any strings inside those strings use " " rather than ' '), you can use regular expressions (re module)

>>> flattener = re.compile("\'.*?\'")
>>> flattener
<_sre.SRE_Pattern object at 0x10d439ca8>
>>> stred = str(in_list)
>>> outed = flattener.findall(stred)

The above code converts in_list into a string, uses the regex to find all the substrings within quotes (i.e. each item of the list) and spits them out as a list.

if x is a vector with raw scores then scale(x) is a vector with standardized scores.

Or manually: (x-mean(x))/sd(x)

LayoutInflater.from(context).inflate(R.layout.row_payment_gateway_item, null);

As mentioned in the comments height:100% relies on the height of the parent container being explicitly defined. One way to achieve what you want is to use absolute/relative positioning, and specifying the left/right/top/bottom properties to "stretch" the content out to fill the available space. I have implemented what I gather you want to achieve in jsfiddle. Try resizing the Result window and you will see the content resizes automatically.

The limitation of this approach in your case is that you have to specify an explicit margin-top on the parent container to offset its contents down to make room for the header content. You can make it dynamic if you throw in javascript though.

Use this:

([^,;]*[,;])*

This is in deed due to characters messing around with the data. Using htmlentities($yourText) worked for me (I had html code inside the xml document). See http://uk3.php.net/htmlentities.

The easiest way to do this, with excellent performance and compatibility with both old and new browsers, is to include either Lo-Dash or Underscore in your page.

Then you can use either _.size(object) or _.keys(object).length

For your obj.Data, you could test this with:

console.log( _.size(obj.Data) );

or:

console.log( _.keys(obj.Data).length );

Lo-Dash and Underscore are both excellent libraries; you would find either one very useful in your code. (They are rather similar to each other; Lo-Dash is a newer version with some advantanges.)

Alternatively, you could include this function in your code, which simply loops through the object's properties and counts them:

function ObjectLength( object ) {
    var length = 0;
    for( var key in object ) {
        if( object.hasOwnProperty(key) ) {
            ++length;
        }
    }
    return length;
};

You can test this with:

console.log( ObjectLength(obj.Data) );

That code is not as fast as it could be in modern browsers, though. For a version that's much faster in modern browsers and still works in old ones, you can use:

function ObjectLength_Modern( object ) {
    return Object.keys(object).length;
}

function ObjectLength_Legacy( object ) {
    var length = 0;
    for( var key in object ) {
        if( object.hasOwnProperty(key) ) {
            ++length;
        }
    }
    return length;
}

var ObjectLength =
    Object.keys ? ObjectLength_Modern : ObjectLength_Legacy;

and as before, test it with:

console.log( ObjectLength(obj.Data) );

This code uses Object.keys(object).length in modern browsers and falls back to counting in a loop for old browsers.

But if you're going to all this work, I would recommend using Lo-Dash or Underscore instead and get all the benefits those libraries offer.

I set up a jsPerf that compares the speed of these various approaches. Please run it in any browsers you have handy to add to the tests.

Thanks to Barmar for suggesting Object.keys for newer browsers in his answer.

Firstly, check the IP address that your application has bound to. It could only be binding to a local address, for example, which would mean that you'd never see it from a different machine regardless of firewall states.

You could try using a portscanner like nmap to see if the port is open and visible externally... it can tell you if the port is closed (there's nothing listening there), open (you should be able to see it fine) or filtered (by a firewall, for example).

According to the GF Administration Guide:

For a valid JVM installation, locations are checked in the following order: a. domain.xml (java-home inside java-config) b. asenv.conf (setting AS_JAVA="path to java home")

I had to add both these settings to make it work. Otherwise 'asadmin stop-domain domain1' wouldn't work. I guess that GF uses a. and asadmin uses b.

(On Windows: b. asenv.bat)

What's probably happening is that React thinks that only one MyInput (unemployment-duration) is added between the renders. As such, the job-title never gets replaced with the unemployment-reason, which is also why the predefined values are swapped.

When React does the diff, it will determine which components are new and which are old based on their key property. If no such key is provided in the code, it will generate its own.

The reason why the last code snippet you provide works is because React essentially needs to change the hierarchy of all elements under the parent div and I believe that would trigger a re-render of all children (which is why it works). Had you added the span to the bottom instead of the top, the hierarchy of the preceding elements wouldn't change, and those element's wouldn't re-render (and the problem would persist).

Here's what the official React documentation says:

The situation gets more complicated when the children are shuffled around (as in search results) or if new components are added onto the front of the list (as in streams). In these cases where the identity and state of each child must be maintained across render passes, you can uniquely identify each child by assigning it a key.

When React reconciles the keyed children, it will ensure that any child with key will be reordered (instead of clobbered) or destroyed (instead of reused).

You should be able to fix this by providing a unique key element yourself to either the parent div or to all MyInput elements.

For example:

render(){
    if (this.state.employed) {
        return (
            <div key="employed">
                <MyInput ref="job-title" name="job-title" />
            </div>
        );
    } else {
        return (
            <div key="notEmployed">
                <MyInput ref="unemployment-reason" name="unemployment-reason" />
                <MyInput ref="unemployment-duration" name="unemployment-duration" />
            </div>
        );
    }
}

OR

render(){
    if (this.state.employed) {
        return (
            <div>
                <MyInput key="title" ref="job-title" name="job-title" />
            </div>
        );
    } else {
        return (
            <div>
                <MyInput key="reason" ref="unemployment-reason" name="unemployment-reason" />
                <MyInput key="duration" ref="unemployment-duration" name="unemployment-duration" />
            </div>
        );
    }
}

Now, when React does the diff, it will see that the divs are different and will re-render it including all of its' children (1st example). In the 2nd example, the diff will be a success on job-title and unemployment-reason since they now have different keys.

You can of course use any keys you want, as long as they are unique.

Update August 2017

For a better insight into how keys work in React, I strongly recommend reading my answer to Understanding unique keys in React.js.

Update November 2017

This update should've been posted a while ago, but using string literals in ref is now deprecated. For example ref="job-title" should now instead be ref={(el) => this.jobTitleRef = el} (for example). See my answer to Deprecation warning using this.refs for more info.

At times, if we forget the

return self.cleaned_data 

in the clean function of django forms, we will not have any data though the form.is_valid() will return True.

You can use a simple list of names :

DF <- data.frame(
  x=1:10,
  y=10:1,
  z=rep(5,10),
  a=11:20
)
drops <- c("x","z")
DF[ , !(names(DF) %in% drops)]

Or, alternatively, you can make a list of those to keep and refer to them by name :

keeps <- c("y", "a")
DF[keeps]

EDIT : For those still not acquainted with the drop argument of the indexing function, if you want to keep one column as a data frame, you do:

keeps <- "y"
DF[ , keeps, drop = FALSE]

drop=TRUE (or not mentioning it) will drop unnecessary dimensions, and hence return a vector with the values of column y.

As you've indicated, you can't output NULL in an excel formula. I think this has to do with the fact that the formula itself causes the cell to not be able to be NULL. "" is the next best thing, but sometimes it's useful to use 0.

--EDIT--

Based on your comment, you might want to check out this link. http://peltiertech.com/WordPress/mind-the-gap-charting-empty-cells/

It goes in depth on the graphing issues and what the various values represent, and how to manipulate their output on a chart.

I'm not familiar with VSTO I'm afraid. So I won't be much help there. But if you are really placing formulas in the cell, then there really is no way. ISBLANK() only tests to see if a cell is blank or not, it doesn't have a way to make it blank. It's possible to write code in VBA (and VSTO I imagine) that would run on a worksheet_change event and update the various values instead of using formulas. But that would be cumbersome and performance would take a hit.

Another option is the sendEmail script http://caspian.dotconf.net/menu/Software/SendEmail/, it also allows you to set the message type as html and include a file as the message body. See the link for details.

I have came across with this issue. When we call the camera and release the views produced this issue. For an example call an camera and set view nil in viewDidDisappear method this error will come since there is not callback for camera event. Make sure about this case too for this error.

curl doesn't have an option to that (without also specifying the filename), but wget does. The directory can be relative or absolute. Also, the directory will automatically be created if it doesn't exist.

wget -P relative/dir "$url"

wget -P /absolute/dir "$url"

If anyone came to this question looking for ways to add multiple parameters at the same time (my case), you can use .params with a MultivalueMap instead of adding each .param :

LinkedMultiValueMap<String, String> requestParams = new LinkedMultiValueMap<>()
requestParams.add("id", "1");
requestParams.add("name", "john");
requestParams.add("age", "30");

mockMvc.perform(get("my/endpoint").params(requestParams)).andExpect(status().isOk())

1) you are calling it wrong way try:

$(input[name="searchBar"]).val('hi')

2) if it doesn't work call your .js file at the end of the page or trigger your function on document.ready event

$(document).ready(function() {
  $(input[name="searchBar"]).val('hi');
});

find location -ctime time_period

Examples of time_period:

• More than 30 days ago: -ctime +30

• Less than 30 days ago: -ctime -30

• Exactly 30 days ago: -ctime 30

I agree with the answers given here (method does not use self and therefore could be decorated with @staticmethod).

I'd like to add that you maybe want to move the method to a top-level function instead of a static method inside a class. For details see this question and the accepted answer: python - should I use static methods or top-level functions

Moving the method to a top-level function will fix the PyCharm warning, too.

This is happening because there is no package cache in the image, you need to run:

apt-get -qq update

before installing packages, and if your command is in a Dockerfile, you'll then need:

apt-get -qq -y install curl

After that install ZSH and GIT Core:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird since sh does not understand the source command. So, you do this to install zsh:

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

and then you change your shell to zsh:

chsh -s `which zsh`

and then restart:

sudo shutdown -r 0

This problem is explained in depth in this issue.

I think you should read this to learn a little about submodule. It's well-written, and it doesn't take much time to read it.

Using "List" you can prevent casting errors. It is very useful to avoid a runtime casting error.

Example:

Here (using ArrayList) you can compile this code but you will see an execution error later.

    // Create a new ArrayList


    System.Collections.ArrayList mixedList = new System.Collections.ArrayList();


    // Add some numbers to the list
    mixedList.Add(7);
    mixedList.Add(21);


    // Add some strings to the list
    mixedList.Add("Hello");
    mixedList.Add("This is going to be a problem");




    System.Collections.ArrayList intList = new System.Collections.ArrayList();
    System.Collections.ArrayList strList = new System.Collections.ArrayList();


    foreach (object obj in mixedList)
    {
        if (obj.GetType().Equals(typeof(int)))
        {
            intList.Add(obj);
        }
        else if (obj.GetType().Equals(typeof(string)))
        {
            strList.Add(obj);
        }
        else
        {
            // error.
        }
    }

Its all depend on your client data access-layer. Many ORM frameworks rely on explicitly querying the SCOPE_IDENTITY during the insert operation.

If you are in complete control over the data access layer then is arguably better to return SCOPE_IDENTITY() as an output parameter. Wrapping the return in a result set adds unnecessary meta data overhead to describe the result set, and complicates the code to process the requests result.

If you prefer a result set return, then again is arguable better to use the OUTPUT clause:

INSERT INTO  MyTable (col1, col2, col3)
OUTPUT INSERTED.id, col1, col2, col3
VALUES (@col1, @col2, @col3);

This way you can get the entire inserted row back, including default and computed columns, and you get a result set containing one row for each row inserted, this working correctly with set oriented batch inserts.

Overall, I can't see a single case when returning SCOPE_IDENTITY() as a result set would be a good practice.

To skip the first line just call:

next(inf)

Files in Python are iterators over lines.

java.io.File doesn't represent an open file, it represents a path in the filesystem. Therefore having close method on it doesn't make sense.

Actually, this class was misnamed by the library authors, it should be called something like Path.

I came across this myself. I used .on so it looks a bit different but I did this:

 $('#element').on('keypress', function() {
   //code to be executed
 }).on('keydown', function(e) {
   if (e.keyCode==8)
     $('element').trigger('keypress');
 });

Adding my Work Around here. I needed to delete ssn typed by user so i did this in jQuery

  $(this).bind("keydown", function (event) {
        // Allow: backspace, delete
        if (event.keyCode == 46 || event.keyCode == 8) 
        {
            var tempField = $(this).attr('name');
            var hiddenID = tempField.substr(tempField.indexOf('_') + 1);
            $('#' + hiddenID).val('');
            $(this).val('')
            return;
        }  // Allow: tab, escape, and enter
        else if (event.keyCode == 9 || event.keyCode == 27 || event.keyCode == 13 ||
        // Allow: Ctrl+A
        (event.keyCode == 65 && event.ctrlKey === true) ||
        // Allow: home, end, left, right
        (event.keyCode >= 35 && event.keyCode <= 39)) {
            // let it happen, don't do anything
            return;
        }
        else 
        {
            // Ensure that it is a number and stop the keypress
            if (event.shiftKey || (event.keyCode < 48 || event.keyCode > 57) &&       (event.keyCode < 96 || event.keyCode > 105)) 
            {
                event.preventDefault();
            }
        }
    });
