shuffle(names) is an in-place operation. Drop the assignment.

This function returns None and that's why you have the error:

I started using the 'prefix-free' Script available at http://leaverou.github.io/prefixfree so I don't have to take care about the vendor prefixes. It neatly takes care of setting the correct vendor prefix behind the scenes for you. Plus a jQuery Plugin is available as well so one can still use jQuery's .css() method without code changes, so the suggested line in combination with prefix-free would be all you need:

$('.user-text').css('transform', 'scale(' + ui.value + ')');

If you are not tweaking the curl command too much you can also go and call the curl command directly

import shlex
cmd = '''curl -X POST -d  '{"nw_src": "10.0.0.1/32", "nw_dst": "10.0.0.2/32", "nw_proto": "ICMP", "actions": "ALLOW", "priority": "10"}' http://localhost:8080/firewall/rules/0000000000000001'''
args = shlex.split(cmd)
process = subprocess.Popen(args, shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = process.communicate()

I got a similar prompt. It was because I had specified the x-axis in terms of some percentage (for example: 10%A, 20%B,....). So an alternate approach could be that you multiply these values and write them in the simplest form.

Here's my example crontab I always use as a template:

    # Use the hash sign to prefix a comment
    # +---------------- minute (0 - 59)
    # |  +------------- hour (0 - 23)
    # |  |  +---------- day of month (1 - 31)
    # |  |  |  +------- month (1 - 12)
    # |  |  |  |  +---- day of week (0 - 7) (Sunday=0 or 7)
    # |  |  |  |  |
    # *  *  *  *  *  command to be executed
    #--------------------------------------------------------------------------

To run my cron job every Monday, Wednesady and Friday at 7:00PM, the result will be:

      0 19 * * 1,3,5 nohup /home/lathonez/script.sh > /tmp/script.log 2>&1

Javadoc to the rescue :

A Scanner breaks its input into tokens using a delimiter pattern, which by default matches whitespace

nextLine is probably the method you should use.

easy just use this command where you .git folder placed

git config --get remote.origin.url

if you are connected to network

git remote show origin

it will show you the URL that a local Git repository was originally cloned from.

hope this help

The answer is NO.

The reason is provided in the flexbox specification:

6. Flex Lines

In a multi-line flex container, the cross size of each line is the minimum size necessary to contain the flex items on the line.

In other words, when there are multiple lines in a row-based flex container, the height of each line (the "cross size") is the minimum height necessary to contain the flex items on the line.

Equal height rows, however, are possible in CSS Grid Layout:

• Equal height rows in CSS Grid Layout

Otherwise, consider a JavaScript alternative.

It is also possible to use enumeration.

typedef enum {
    typeNo1 = 1,
    typeNo2,
    typeNo3,
    typeNo4,
    NumOfTypes = typeNo4
}  TypeOfSomething;

We need a trick here...

Normal select-dropdown things won't accept styles. BUT. If there's a "size" parameter in the tag, almost any CSS will apply. With this in mind, I've created a fiddle that's practically equivalent to a normal select tag, plus the value can be edited manually like a ComboBox in visual languages (unless you put readonly in the input tag).

A simplified example:

<style>

    /* only these 2 lines are truly required */
    .stylish span {position:relative;}
    .stylish select {position:absolute;left:0px;display:none}

    /* now you can style the hell out of them */
    .stylish input    { ... }
    .stylish select   { ... }
    .stylish option   { ... }
    .stylish optgroup { ... }

</style>
...
<div class="stylish">
    <label> Choose your superhero: </label>
    <span>
        <input onclick="$(this).closest('div').find('select').slideToggle(110)">
        <br>
        <select size=15 onclick="$(this).hide().closest('div').find('input').val($(this).find('option:selected').text());">

            <optgroup label="Fantasy"></optgroup>
            <option value="gandalf">Gandalf</option>
            <option value="harry">Harry Potter</option>
            <option value="jon">Jon Snow</option>

            <optgroup label="Comics"></optgroup>
            <option value="tony">Tony Stark</option>
            <option value="steve">Steven Rogers</option>
            <option value="natasha">Natasha Romanova</option>

        </select>
    </span>
    <!--

        For the sake of simplicity, I used jQuery here.
        Today it's easy to do the same without it, now
        that we have querySelector(), closest(), etc.

    -->
</div>

A live example:

https://jsfiddle.net/7ac9us70/1052/

Note 1: Sorry for the gradients & all fancy stuff, no they're not necessary, yes I'm showing off, I know, hashtag onlyhuman, hashtag notproud.

Note 2: Those <optgroup> tags don't encapsulate the options belonging under them as they normally should; this is intentional. It's better for the styling (the well-mannered way would be a lot less stylable), and yes this is painless and works in every browser.

If you are going to do it in pure CSS (using scss) but you have different elements/classes inside the same parent class you can use this version!!

  &:first-of-type:nth-last-of-type(1) {
    max-width: 100%;
  }

  @for $i from 2 through 10 {
    &:first-of-type:nth-last-of-type(#{$i}),
    &:first-of-type:nth-last-of-type(#{$i}) ~ & {
      max-width: (100% / #{$i});
    }
  }

Here is a video from Google Developers showing how to list all videos in a channel in v3 of the YouTube API.

There are two steps:

1. Query Channels to get the "uploads" Id. eg https://www.googleapis.com/youtube/v3/channels?id={channel Id}&key={API key}&part=contentDetails

2. Use this "uploads" Id to query PlaylistItems to get the list of videos. eg https://www.googleapis.com/youtube/v3/playlistItems?playlistId={"uploads" Id}&key={API key}&part=snippet&maxResults=50

You have to change server cert from cert.pem to fullchain.pem
I had the same issue with Perl HTTPS Daemon:
I have changed:
SSL_cert_file => '/etc/letsencrypt/live/mydomain/cert.pem'
to:
SSL_cert_file => '/etc/letsencrypt/live/mydomain/fullchain.pem'

NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];  

or use

NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM 
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);

did you tried converting the first char of the string to lowercase on if(fruits[i].charAt(0) == currChar) and char currChar = fruits[0].charAt(0) statements?

Socket.io 1.7.3(+) :

function getConnectedList ()
{
    let list = []
    
    for ( let client in io.sockets.connected )
    {
        list.push(client)
    }
    
    return list
}

console.log( getConnectedList() )

// returns [ 'yIfhb2tw7mxgrnF6AAAA', 'qABFaNDSYknCysbgAAAB' ]

1. Create .env.development, .env.production files if not exists and add there your API endpoint, for example: VUE_APP_API_ENDPOINT ='http://localtest.me:8000'
2. In main.js file, add this line after imports: axios.defaults.baseURL = process.env.VUE_APP_API_ENDPOINT

And that's it. Axios default base Url is replaced with build mode specific API endpoint. If you need specific baseURL for specific request, do it like this:

this.$axios({ url: 'items', baseURL: 'http://new-url.com' })

If you want to use loops you can also do:

$array = array('lastname', 'email', 'phone');
foreach($array as &$value){
   $value = "'$value'";
}
$comma_separated = implode(",", $array);

No, you cannot do that. I invite you to read a POST definition.

Here is my best shot at it. I added another Div and made it red and changed you parent's height to 200px just to test it. The idea is the the child now becomes the grandchild and the parent becomes the grandparent. So the parent respects its parent. Hope you get my idea.

<html>
  <body>
    <div style="background-color: blue; padding: 10px; position: relative; height: 200px;">
     <div style="background-color: red;  position: relative; height: 100%;">    
        <div style="background-color: gray; position: absolute; left: 0px; right: 0px;bottom: 0px;">css sux</div>
     </div>
    </div>
  </body>
</html>

Edit:

I think what you are trying to do can't be done. Absolute position means that you are going to give it co-ordinates it must honor. What if the parent has a padding of 5px. And you absolutely position the child at top: -5px; left: -5px. How is it suppose to honor the parent and you at the same time??

My solution

If you want it to honor the parent, don't absolutely position it then.

The get method of the HashMap is returning an Object, but the variable current is expected to take a ArrayList:

ArrayList current = new ArrayList();
// ...
current = dictMap.get(dictCode);

For the above code to work, the Object must be cast to an ArrayList:

ArrayList current = new ArrayList();
// ...
current = (ArrayList)dictMap.get(dictCode);

However, probably the better way would be to use generic collection objects in the first place:

HashMap<String, ArrayList<Object>> dictMap =
    new HashMap<String, ArrayList<Object>>();

// Populate the HashMap.

ArrayList<Object> current = new ArrayList<Object>();      
if(dictMap.containsKey(dictCode)) {
    current = dictMap.get(dictCode);   
}

The above code is assuming that the ArrayList has a list of Objects, and that should be changed as necessary.

For more information on generics, The Java Tutorials has a lesson on generics.

It simply calls the default constructor of the superclass.

My simple way:

function Timer (callback, delay) {
  let callbackStartTime
  let remaining = 0

  this.timerId = null
  this.paused = false

  this.pause = () => {
    this.clear()
    remaining -= Date.now() - callbackStartTime
    this.paused = true
  }
  this.resume = () => {
    window.setTimeout(this.setTimeout.bind(this), remaining)
    this.paused = false
  }
  this.setTimeout = () => {
    this.clear()
    this.timerId = window.setInterval(() => {
      callbackStartTime = Date.now()
      callback()
    }, delay)
  }
  this.clear = () => {
    window.clearInterval(this.timerId)
  }

  this.setTimeout()
}

How to use:

let seconds = 0_x000D_
const timer = new Timer(() => {_x000D_
  seconds++_x000D_
  _x000D_
  console.log('seconds', seconds)_x000D_

The code is written quickly and did not refactored, raise the rating of my answer if you want me to improve the code and give ES2015 version (classes).

Cracked it. Just @Damnum steps and then follow the path to run xcode. Bad way but running like a charm.

Double click to /Applications/Xcode102.app/Contents/MacOS/Xcode

For me, the issue was that there was a proxy set in /etc/ssh/ssh_config and it was down, solved the issue by whitelisting the remote git IP and removing the proxy line.

Hope this helps someone.

There are few modes to open file (read, write etc..)

If you want to read from file you should type file = open("File.txt","r"), if write than file = open("File.txt","w"). You need to give the right permission regarding your usage.

more modes:

• r. Opens a file for reading only.
• rb. Opens a file for reading only in binary format.
• r+ Opens a file for both reading and writing.
• rb+ Opens a file for both reading and writing in binary format.
• w. Opens a file for writing only.
• you can find more modes in here

I got Jupyter notebook running in Windows 10. I found the easiest way to accomplish this task without relying upon a distro like Anaconda was to use Cygwin.

In Cygwin install python2, python2-devel, python2-numpy, python2-pip, tcl, tcl-devel, (I have included a image below of all packages I installed) and any other python packages you want that are available. This is by far the easiest option.

Then run this command to just install jupyter notebook:

python -m pip install jupyter

Below is the actual commands I ran to add more libraries just in case others need this list too:

python -m pip install scipy

python -m pip install scikit-learn

python -m pip install sklearn

python -m pip install pandas

python -m pip install matplotlib

python -m pip install jupyter

If any of the above commands fail do not worry the solution is pretty simple most of the time. What you do is look at the build failure for whatever missing package / library.

Say it is showing a missing pyzmq then close Cygwin, re-open the installer, get to the package list screen, show "full" for all, then search for the name like zmq and install those libraries and re-try the above commands.

Using this approach it was fairly simple to eventually work through all the missing dependencies successfully.

Cygwin package list

Once everything is installed then run in Cygwin goto the folder you want to be the "root" for the notebook ui tree and type:

jupyter notebook

This will start up the notebook and show some output like below:

$ jupyter notebook
[I 19:05:30.459 NotebookApp] Serving notebooks from local directory: 
[I 19:05:30.459 NotebookApp] 0 active kernels
[I 19:05:30.459 NotebookApp] The Jupyter Notebook is running at: 
[I 19:05:30.459 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

Copy/paste this URL into your browser when you connect for the first time, to login with a token:

http://localhost:8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

First step is to find out which ruby is being called:

$ which ruby

Your system says:

/usr/bin/ruby

This is NOT the shim used by rbenv, which (on MacOS) should look like:

/Users/<username>/.rbenv/shims/ruby

The shim is actually a script that acts like a redirect to the version of ruby you set.

I recommend that for trouble shooting you unset the project specific "local" version, and the shell specific "shell" version and just test using the "global" version setting which is determined in a plain text file in ~/.rbenv/version which will just be the version number "1.9.3" in your case.

$ rbenv global 1.9.3
$ rbenv local --unset
$ rbenv shell --unset

You can do ls -laG in the root of your project folder (not the home folder) to make sure there is no longer a ".ruby-version" file there.

You can use rbenv versions to identify which version rbenv is set to use (and the location and name of the file that is setting that):

$ rbenv versions

NONE OF THAT MATTERS until you set the path correctly.

Use this to make sure your *MacOS will obey you:

$ rbenv init -

Followed by:

$ which ruby

To make sure it looks like:

/Users/<username>/.rbenv/shims/ruby

Then run this to add the line to your profile so it runs each time you open a new terminal window:

$ echo 'eval "$(rbenv init -)"' >> ~/.bash_profile

There are other ways to modify the path, feel free to substitute any of them instead of running the rbenv init.

NOTE: reinstall Rails with:

$ gem install rails

If you were trying to run Ruby on Rails, then you need to have this all working first, then install the rails gem again. A previous install of Rails will use a hard coded path to the wrong ruby and several other things will be in the wrong place, so just install the gem again.

P. S. If your MacOS won't obey you (*mentioned above) then you may have to find another way to modify your path, but that's unlikely to be a problem because "Macs just work" ;)

It is not possible to save file locally without involving the local client (browser machine) as I could be a great threat to client machine. You can use link to download that file. If you want to store something like Json data on local machine you can use LocalStorage provided by the browsers, Web Storage

In Scala, building up on YourBestBet's solution but simplified:

def prettyDuration(seconds: Long): List[String] = seconds match {
  case t if t < 60      => List(s"${t} seconds")
  case t if t < 3600    => s"${t / 60} minutes" :: prettyDuration(t % 60)
  case t if t < 3600*24 => s"${t / 3600} hours" :: prettyDuration(t % 3600)
  case t                => s"${t / (3600*24)} days" :: prettyDuration(t % (3600*24))
}

val dur = prettyDuration(12345).mkString(", ") // => 3 hours, 25 minutes, 45 seconds

I'm not sure how FWIX.com is doing it specifically, but I'd wager they are using Custom Overlays.

In my case after trying everything for three days, solved by just starting Visual Studio by "Run as Administrator."

Solution: Step1: Have to remove “lock” file which present under “.svn” hidden file. Step2: In case if there is no “lock” file then you would see “we.db” you have to open this database and need to delete content alone from the following tables – lock – wc_lock Step3: Clean your project Step4: Try to commit now. Step5: Done.

A simple solution for me was to go to Properties -> Java Build Path -> Order and Export, then check the Apache Tomcat library. This is assumes you've already set Tomcat as your deployment target and are still getting the error.

I would use the cat() command as in this example:

> cat("Hello",file="outfile.txt",sep="\n")
> cat("World",file="outfile.txt",append=TRUE)

You can then view the results from with R with

> file.show("outfile.txt")
hello
world

firstarray and secondarray are converted to a pointer to int, when passed to printarray().

printarray(int arg[], ...) is equivalent to printarray(int *arg, ...)

However, this is not specific to C++. C has the same rules for passing array names to a function.

In addition to the answers above, for those who want to process CSV and then export to csv, parquet or SQL, d6tstack is another good option. You can load multiple files and it deals with data schema changes (added/removed columns). Chunked out of core support is already built in.

def apply(dfg):
    # do stuff
    return dfg

c = d6tstack.combine_csv.CombinerCSV([bigfile.csv], apply_after_read=apply, sep=',', chunksize=1e6)

# or
c = d6tstack.combine_csv.CombinerCSV(glob.glob('*.csv'), apply_after_read=apply, chunksize=1e6)

# output to various formats, automatically chunked to reduce memory consumption
c.to_csv_combine(filename='out.csv')
c.to_parquet_combine(filename='out.pq')
c.to_psql_combine('postgresql+psycopg2://usr:pwd@localhost/db', 'tablename') # fast for postgres
c.to_mysql_combine('mysql+mysqlconnector://usr:pwd@localhost/db', 'tablename') # fast for mysql
c.to_sql_combine('postgresql+psycopg2://usr:pwd@localhost/db', 'tablename') # slow but flexible

This works.

<html>
<head>
<script type = "text/javascript">
function write_below(form)
{
var input = document.forms.write.input_to_write.value;
document.getElementById('write_here').innerHTML="Your input was:"+input;
return false;
}
</script>
</head>

<!--Insert more code here-->
<body>
<form name='write' onsubmit='return write_below(this);'>
<input type = "text" name='input_to_write'>
<input type = "button" value = "submit" />
</form>
<div id='write_here'></div></body>
</html>

Returning false from the function never posts it to other page,but does edit the html content.

Make sure you're doing this for a good reason, a simple function like the following would allow static typing and allows your IDE to do things like "Find References" and Refactor -> Rename.

public Task <T> factory (String name)
{
  Task <T> result;

  if (name.CompareTo ("A") == 0)
  {
    result = new TaskA ();
  }
  else if (name.CompareTo ("B") == 0)
  {
    result = new TaskB ();
  }

  return result;
}

ptomato's code can also be written in a cleaner manner like:

ifeq ($(TARGET_CPU),x86)
  TARGET_CPU_IS_X86 := 1
else ifeq ($(TARGET_CPU),x86_64)
  TARGET_CPU_IS_X86 := 1
else
  TARGET_CPU_IS_X86 := 0
endif

This doesn't answer OP's question but as it's the top result on google, I'm adding it here in case it's useful to anyone else.

Therefore the best thing I would do is also to comment out the PHP...

https://thomashunter.name/blog/simple-php-namespace-friendly-autoloader-class/

You’ll want to put your class files into a folder named Classes, which is in the same directory as the entry point into your PHP application. If classes use namespaces, the namespaces will be converted into the directory structure.

Unlike a lot of other auto-loaders, underscores will not be converted into directory structures (it’s tricky to do PHP < 5.3 pseudo namespaces along with PHP >= 5.3 real namespaces).

<?php
class Autoloader {
    static public function loader($className) {
        $filename = "Classes/" . str_replace("\\", '/', $className) . ".php";
        if (file_exists($filename)) {
            include($filename);
            if (class_exists($className)) {
                return TRUE;
            }
        }
        return FALSE;
    }
}
spl_autoload_register('Autoloader::loader');

You’ll want to place the following code into your main PHP script (entry point):

require_once("Classes/Autoloader.php");

Here’s an example directory layout:

index.php
Classes/
  Autoloader.php
  ClassA.php - class ClassA {}
  ClassB.php - class ClassB {}
  Business/
    ClassC.php - namespace Business; classC {}
    Deeper/
      ClassD.php - namespace Business\Deeper; classD {}

My experience in Visual Studio 2010 is that there are two changes needed so as to not need DLL's. From the project property page (right click on the project name in the Solution Explorer window):

1. Under Configuration Properties --> General, change the "Use of MFC" field to "Use MFC in a Static Library".

2. Under Configuration Properties --> C/C++ --> Code Generation, change the "Runtime Library" field to "Multi-Threaded (/MT)"

Not sure why both were needed. I used this to remove a dependency on glut32.dll.

Added later: When making these changes to the configurations, you should make them to "All Configurations" --- you can select this at the top of the Properties window. If you make the change to just the Debug configuration, it won't apply to the Release configuration, and vice-versa.

Run like:

  $ mvn help:describe -DartifactId=maven-war-plugin -DgroupId=org.apache.maven.plugins

for plug-in that have no version. You get output:

Name: Maven WAR Plugin
Description: Builds a Web Application Archive (WAR) file from the project
  output and its dependencies.
Group Id: org.apache.maven.plugins
Artifact Id: maven-war-plugin
Version: 2.2
Goal Prefix: war

Use version that shown in output.

UPDATE If you want to select among list of versions, use http://search.maven.org/ or http://mvnrepository.com/ Note that your favorite Java IDE must have Maven package search dialog. Just check docs.

SUPER UPDATE I also use:

$ mvn dependency:tree
$ mvn dependency:list
$ mvn dependency:resolve
$ mvn dependency:resolve-plugins  # <-- THIS

Recently I discover how to get latest version for plug-in (or library) so no longer needs for googling or visiting Maven Central:

$ mvn versions:display-dependency-updates
$ mvn versions:display-plugin-updates     # <-- THIS

In the case of local variables, I tend to avoid this. It causes visual clutter, and is generally unnecessary - a function should be short enough or focus on a single impact to let you quickly see that you are modify something that shouldn't be.

In the case of magic numbers, I would put them as a constant private field anyway rather than in the code.

I only use final in situations where it is necessary (e.g., passing values to anonymous classes).

I know this was posted about a year ago, but this is for users for future reference.

I came across similar issue. In my case (i will try to be brief, please do let me know if you would like more detail), i was trying to check if a string was empty or not (string is the subject of an email). It always returned the same error message no matter what i did. I knew i was doing it right but it still kept throwing the same error message. Then it dawned in me that, i was checking if the subject (string) of an email (instance/object), what if the email(instance) was already a null at the first place. How could i check for a subject of an email, if the email is already a null..i checked if the the email was empty, it worked fine.

while checking for the subject(string) i used IsNullorWhiteSpace(), IsNullOrEmpty() methods.

if (email == null)
{     
     break;    
}
else
{    
     // your code here    
}

Given

    volumes:
      - /dir/on/host:/var/www/html

if /dir/on/host doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html. Whatever content you had before in /var/www/html inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.

Shefali's solution for UIImageView works great, but it needs a little modification:

- (void)pinch:(UIPinchGestureRecognizer *)gesture {
    if (gesture.state == UIGestureRecognizerStateEnded
        || gesture.state == UIGestureRecognizerStateChanged) {
        NSLog(@"gesture.scale = %f", gesture.scale);

        CGFloat currentScale = self.frame.size.width / self.bounds.size.width;
        CGFloat newScale = currentScale * gesture.scale;

        if (newScale < MINIMUM_SCALE) {
            newScale = MINIMUM_SCALE;
        }
        if (newScale > MAXIMUM_SCALE) {
            newScale = MAXIMUM_SCALE;
        }

        CGAffineTransform transform = CGAffineTransformMakeScale(newScale, newScale);
        self.transform = transform;
        gesture.scale = 1;
    }
}

(Shefali's solution had the downside that it did not scale continuously while pinching. Furthermore, when starting a new pinch, the current image scale was reset.)

Provided you are running IPython, the %matplotlib inline will make your plot outputs appear and be stored within the notebook.

According to documentation

To set this up, before any plotting or import of matplotlib is performed you must execute the %matplotlib magic command. This performs the necessary behind-the-scenes setup for IPython to work correctly hand in hand with matplotlib; it does not, however, actually execute any Python import commands, that is, no names are added to the namespace.

A particularly interesting backend, provided by IPython, is the inline backend. This is available only for the Jupyter Notebook and the Jupyter QtConsole. It can be invoked as follows:

%matplotlib inline

With this backend, the output of plotting commands is displayed inline within frontends like the Jupyter notebook, directly below the code cell that produced it. The resulting plots will then also be stored in the notebook document.

Use .val() instead of .innerHTML for getting value of selected option

Use .text() for getting text of selected option

Thanks for correcting :)

I had exactly this issue in a recent project which really is a pain in the rear. I finally found it's because the Python we used in Docker has encoding "ansi_x3.4-1968" instead of "utf-8". So if anyone out there using Docker and got this error, following these steps may thoroughly solve your problem.

1. create a file and name it default_locale in the same directory of your Dockerfile, put this line in it,

   environment=LANG="es_ES.utf8", LC_ALL="es_ES.UTF-8", LC_LANG="es_ES.UTF-8"

2. add these to your Dockerfile,

   RUN apt-get clean && apt-get update && apt-get install -y locales

   RUN locale-gen en_CA.UTF-8

   COPY ./default_locale /etc/default/locale

   RUN chmod 0755 /etc/default/locale

   ENV LC_ALL=en_CA.UTF-8

   ENV LANG=en_CA.UTF-8

   ENV LANGUAGE=en_CA.UTF-8

This thoroughly solved my issue when I built and run my Docker again, hopefully this solve your issue also.

Create build.gradle file in facebook sdk project:

apply plugin: 'android-library'

dependencies {
    compile 'com.android.support:support-v4:18.0.+'
}

android {
    compileSdkVersion 8
    buildToolsVersion "19.0.0"

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

Then add include ':libs:facebook' equals <project_directory>/libs/facebook (path to library) in settings.gradle.

This is answering a slightly different question, but since I got stuck on this myself, I hope it might be useful for someone else.

If you want to use allow_redirects=False and get directly to the first redirect object, rather than following a chain of them, and you just want to get the redirect location directly out of the 302 response object, then r.url won't work. Instead, it's the "Location" header:

r = requests.get('http://github.com/', allow_redirects=False)
r.status_code  # 302
r.url  # http://github.com, not https.
r.headers['Location']  # https://github.com/ -- the redirect destination

import os

path, dirs, files = next(os.walk("/usr/lib"))

used !important in CSS property

<div style="color: red;">
    Hello World, How Can I Change The Color To Blue?
</div>

div {
        color: blue !important;
    }

Are you trying to submit a form?

Listen to the submit event instead.

This will handle click and enter.

If you must use enter key...

document.querySelector('#txtSearch').addEventListener('keypress', function (e) {
    if (e.key === 'Enter') {
      // code for enter
    }
});

I know that the question is old, But I would like to share this

I Used this method to import more than 100K records (~5MB) in 0.046sec

Here's how you do it:

LOAD DATA LOCAL INFILE  
'c:/temp/some-file.csv'
INTO TABLE your_awesome_table  
FIELDS TERMINATED BY ',' 
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
(field_1,field_2 , field_3);

It is very important to include the last line , if you have more than one field i.e normally it skips the last field (MySQL 5.6.17)

LINES TERMINATED BY '\n'
(field_1,field_2 , field_3);

Then, assuming you have the first row as the title for your fields, you might want to include this line also

IGNORE 1 ROWS

This is what it looks like if your file has a header row.

LOAD DATA LOCAL INFILE  
'c:/temp/some-file.csv'
INTO TABLE your_awesome_table  
FIELDS TERMINATED BY ',' 
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
IGNORE 1 ROWS
(field_1,field_2 , field_3);

If you're on Linux, or have cygwin available on Windows, you can run the input XML through a simple sed script that will replace <Active>True</Active> with <Active>true</Active>, like so:

cat <your XML file> | sed 'sX<Active>True</Active>X<Active>true</Active>X' | xmllint --schema -

If you're not, you can still use a non-validating xslt pocessor (xalan, saxon etc.) to run a simple xslt transformation on the input, and only then pipe it to xmllint.

What the xsl should contain something like below, for the example you listed above (the xslt processor should be 2.0 capable):

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
    <xsl:output method="xml" indent="yes"/>
    <xsl:template match="/">
    <xsl:for-each select="XML">
        <xsl:for-each select="Active">
            <xsl:value-of select=" replace(current(), 'True','true')"/>
        </xsl:for-each>
    </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

FOR A NICER LOOK&FEEL

You should use jQuery keypress() event in combination with String.fromCharCode(e.which) to get the pressed character. Hence you can calculate what your width will be. Why? Because it will look a lot more sexy :)

Here is a jsfiddle that results in a nice behaviour compared to solutions using the keyup event : http://jsfiddle.net/G4FKW/3/

Below is a vanilla JS which listens to the input event of an <input> element and sets a span sibling to have the same text value in order to measure it.

document.querySelector('input').addEventListener('input', onInput)_x000D_
_x000D_
function onInput(){_x000D_
    var spanElm = this.nextElementSibling;_x000D_
    spanElm.textContent = this.value; // the hidden span takes the value of the input; _x000D_
    this.style.width = spanElm.offsetWidth + 'px'; // apply width of the span to the input_x000D_
};

/* it's important the input and its span have same styling */_x000D_
input, .measure {_x000D_
    padding: 5px;_x000D_
    font-size: 2.3rem;_x000D_
    font-family: Sans-serif;_x000D_
    white-space: pre; /* white-spaces will work effectively */_x000D_
}_x000D_
_x000D_
.measure{  _x000D_
  position: absolute;_x000D_
  left: -9999px;_x000D_

I wrote a module called Ng-Idle that may be useful to you in this situation. Here is the page which contains instructions and a demo.

Basically, it has a service that starts a timer for your idle duration that can be disrupted by user activity (events, such as clicking, scrolling, typing). You can also manually interrupt the timeout by calling a method on the service. If the timeout is not disrupted, then it counts down a warning where you could alert the user they are going to be logged out. If they do not respond after the warning countdown reaches 0, an event is broadcasted that your application can respond to. In your case, it could issue a request to kill their session and redirect to a login page.

Additionally, it has a keep-alive service that can ping some URL at an interval. This can be used by your app to keep a user's session alive while they are active. The idle service by default integrates with the keep-alive service, suspending the pinging if they become idle, and resuming it when they return.

All the info you need to get started is on the site with more details in the wiki. However, here's a snippet of config showing how to sign them out when they time out.

angular.module('demo', ['ngIdle'])
// omitted for brevity
.config(function(IdleProvider, KeepaliveProvider) {
  IdleProvider.idle(10*60); // 10 minutes idle
  IdleProvider.timeout(30); // after 30 seconds idle, time the user out
  KeepaliveProvider.interval(5*60); // 5 minute keep-alive ping
})
.run(function($rootScope) {
    $rootScope.$on('IdleTimeout', function() {
        // end their session and redirect to login
    });
});

Here Swift updated:

let userID = "BOB"  

Declare userDefaults:

let defaults = UserDefaults.standard
defaults.setValue(userID, forKey: "userID")

And get it:

let userID = defaults.object(forKey: "userID")

This untested, but I think you may be able to try something like this:

 $('#listItem').not('span').text();

You're attempting to free something that isn't a pointer to a "freeable" memory address. Just because something is an address doesn't mean that you need to or should free it.

There are two main types of memory you seem to be confusing - stack memory and heap memory.

• Stack memory lives in the live span of the function. It's temporary space for things that shouldn't grow too big. When you call the function main, it sets aside some memory for your variables you've declared (p,token, and so on).

• Heap memory lives from when you malloc it to when you free it. You can use much more heap memory than you can stack memory. You also need to keep track of it - it's not easy like stack memory!

You have a few errors:

• You're trying to free memory that's not heap memory. Don't do that.

• You're trying to free the inside of a block of memory. When you have in fact allocated a block of memory, you can only free it from the pointer returned by malloc. That is to say, only from the beginning of the block. You can't free a portion of the block from the inside.

For your bit of code here, you probably want to find a way to copy relevant portion of memory to somewhere else...say another block of memory you've set aside. Or you can modify the original string if you want (hint: char value 0 is the null terminator and tells functions like printf to stop reading the string).

EDIT: The malloc function does allocate heap memory*.

"9.9.1 The malloc and free Functions

The C standard library provides an explicit allocator known as the malloc package. Programs allocate blocks from the heap by calling the malloc function."

~Computer Systems : A Programmer's Perspective, 2nd Edition, Bryant & O'Hallaron, 2011

EDIT 2: * The C standard does not, in fact, specify anything about the heap or the stack. However, for anyone learning on a relevant desktop/laptop machine, the distinction is probably unnecessary and confusing if anything, especially if you're learning about how your program is stored and executed. When you find yourself working on something like an AVR microcontroller as H2CO3 has, it is definitely worthwhile to note all the differences, which from my own experience with embedded systems, extend well past memory allocation.

For scoping purpose, I use:

custom_object = None

By using this class you can apply "dashed and underline" effect to multiple lines text. to use DashPathEffect you have to turn off hardwareAccelerated of your TextView(though DashPathEffect method has a problem with long text). you can find my sample project here: https://github.com/jintoga/Dashed-Underlined-TextView/blob/master/Untitled.png.

public class DashedUnderlineSpan implements LineBackgroundSpan, LineHeightSpan {

    private Paint paint;
    private TextView textView;
    private float offsetY;
    private float spacingExtra;

    public DashedUnderlineSpan(TextView textView, int color, float thickness, float dashPath,
                               float offsetY, float spacingExtra) {
        this.paint = new Paint();
        this.paint.setColor(color);
        this.paint.setStyle(Paint.Style.STROKE);
        this.paint.setPathEffect(new DashPathEffect(new float[] { dashPath, dashPath }, 0));
        this.paint.setStrokeWidth(thickness);
        this.textView = textView;
        this.offsetY = offsetY;
        this.spacingExtra = spacingExtra;
    }

    @Override
    public void chooseHeight(CharSequence text, int start, int end, int spanstartv, int v,
                             Paint.FontMetricsInt fm) {
        fm.ascent -= spacingExtra;
        fm.top -= spacingExtra;
        fm.descent += spacingExtra;
        fm.bottom += spacingExtra;
    }

    @Override
    public void drawBackground(Canvas canvas, Paint p, int left, int right, int top, int baseline,
                               int bottom, CharSequence text, int start, int end, int lnum) {
        int lineNum = textView.getLineCount();
        for (int i = 0; i < lineNum; i++) {
            Layout layout = textView.getLayout();
            canvas.drawLine(layout.getLineLeft(i), layout.getLineBottom(i) - spacingExtra + offsetY,
                    layout.getLineRight(i), layout.getLineBottom(i) - spacingExtra + offsetY,
                    this.paint);
        }
    }
}

Result:

I had the same error and just wanted to share my solution. In turned out that the minified version of popper had the code in the same line as the comment and so the entire code was commented out. I just pressed enter after the actual comment so the code was on a new line and then it worked fine.

This solution demonstrates how to transform data with Spark native functions which are better than UDFs. It also demonstrates how dropDuplicates which is more suitable than distinct for certain queries.

Suppose you have this DataFrame:

+-------+-------------+
|country|    continent|
+-------+-------------+
|  china|         asia|
| brazil|south america|
| france|       europe|
|  china|         asia|
+-------+-------------+

Here's how to take all the distinct countries and run a transformation:

df
  .select("country")
  .distinct
  .withColumn("country", concat(col("country"), lit(" is fun!")))
  .show()

+--------------+
|       country|
+--------------+
|brazil is fun!|
|france is fun!|
| china is fun!|
+--------------+

You can use dropDuplicates instead of distinct if you don't want to lose the continent information:

df
  .dropDuplicates("country")
  .withColumn("description", concat(col("country"), lit(" is a country in "), col("continent")))
  .show(false)

+-------+-------------+------------------------------------+
|country|continent    |description                         |
+-------+-------------+------------------------------------+
|brazil |south america|brazil is a country in south america|
|france |europe       |france is a country in europe       |
|china  |asia         |china is a country in asia          |
+-------+-------------+------------------------------------+

See here for more information about filtering DataFrames and here for more information on dropping duplicates.

Ultimately, you'll want to wrap your transformation logic in custom transformations that can be chained with the Dataset#transform method.

if you running docker under docker-machine?

execute to get ip:

docker-machine ip <machine>

returns the ip for the machine and try connect mysql:

mysql -h<docker-machine-ip>

This is the implemented code needed:

in Swift 3.0:

var dataString = String(data: fooData, encoding: String.Encoding.utf8)

or just

var dataString = String(data: fooData, encoding: .utf8)

Older swift version:

in Swift 2.0:

import Foundation

var dataString = String(data: fooData, encoding: NSUTF8StringEncoding)

in Swift 1.0:

var dataString = NSString(data: fooData, encoding:NSUTF8StringEncoding)

This solution will not only display all relations but also the constraint name, which is required in some cases (e.g. drop constraint):

SELECT
    CONCAT(table_name, '.', column_name) AS 'foreign key',
    CONCAT(referenced_table_name, '.', referenced_column_name) AS 'references',
    constraint_name AS 'constraint name'
FROM
    information_schema.key_column_usage
WHERE
    referenced_table_name IS NOT NULL;

If you want to check tables in a specific database, add the following:

AND table_schema = 'database_name';

As the error idnicates - "This happens when the section is locked at a parent level". To unlock the section you can use appcmd.exe and execute the following command:

%windir%\system32\inetsrv\appcmd.exe unlock config -section:system.webServer/handlers -commitpath:apphost

For more information on about section locking and what a parent configuration context is refer to IIS documentation.

I am using a .Net Core 2.1 Web Application and could not get a single answer here to work. I either got a blank parameter (if the method was called at all) or a 500 server error. I started playing with every possible combination of answers and finally got a working result.

In my case the solution was as follows:

Script - stringify the original array (without using a named property)

    $.ajax({
        type: 'POST',
        contentType: 'application/json; charset=utf-8',
        url: mycontrolleraction,
        data: JSON.stringify(things)
    });

And in the controller method, use [FromBody]

    [HttpPost]
    public IActionResult NewBranch([FromBody]IEnumerable<Thing> things)
    {
        return Ok();
    }

Failures include:

• Naming the content

  data: { content: nodes }, // Server error 500

• Not having the contentType = Server error 500

Notes

• dataType is not needed, despite what some answers say, as that is used for the response decoding (so not relevant to the request examples here).
• List<Thing> also works in the controller method

Another way to escape quotes (though probably not preferable), which I've found used in certain places is to use multiple double-quotes. For the purpose of making other people's code legible, I'll explain.

Here's a set of basic rules:

1. When not wrapped in double-quoted groups, spaces separate parameters:
   program param1 param2 param 3 will pass four parameters to program.exe:
        param1, param2, param, and 3.
2. A double-quoted group ignores spaces as value separators when passing parameters to programs:
   program one two "three and more" will pass three parameters to program.exe:
        one, two, and three and more.
Now to explain some of the confusion:
3. Double-quoted groups that appear directly adjacent to text not wrapped with double-quotes join into one parameter:
   hello"to the entire"world acts as one parameter: helloto the entireworld.
Note: The previous rule does NOT imply that two double-quoted groups can appear directly adjacent to one another.
4. Any double-quote directly following a closing quote is treated as (or as part of) plain unwrapped text that is adjacent to the double-quoted group, but only one double-quote:
   "Tim says, ""Hi!""" will act as one parameter: Tim says, "Hi!"

Thus there are three different types of double-quotes: quotes that open, quotes that close, and quotes that act as plain-text.
Here's the breakdown of that last confusing line:

"   open double-quote group
T   inside ""s
i   inside ""s
m   inside ""s
    inside ""s - space doesn't separate
s   inside ""s
a   inside ""s
y   inside ""s
s   inside ""s
,   inside ""s
    inside ""s - space doesn't separate
"   close double-quoted group
"   quote directly follows closer - acts as plain unwrapped text: "
H   outside ""s - gets joined to previous adjacent group
i   outside ""s - ...
!   outside ""s - ...
"   open double-quote group
"   close double-quote group
"   quote directly follows closer - acts as plain unwrapped text: "

Thus, the text effectively joins four groups of characters (one with nothing, however):
Tim says,  is the first, wrapped to escape the spaces
"Hi! is the second, not wrapped (there are no spaces)
 is the third, a double-quote group wrapping nothing
" is the fourth, the unwrapped close quote.

As you can see, the double-quote group wrapping nothing is still necessary since, without it, the following double-quote would open up a double-quoted group instead of acting as plain-text.

From this, it should be recognizable that therefore, inside and outside quotes, three double-quotes act as a plain-text unescaped double-quote:

"Tim said to him, """What's been happening lately?""""

will print Tim said to him, "What's been happening lately?" as expected. Therefore, three quotes can always be reliably used as an escape.
However, in understanding it, you may note that the four quotes at the end can be reduced to a mere two since it technically is adding another unnecessary empty double-quoted group.

Here are a few examples to close it off:

program a b                       REM sends (a) and (b)
program """a"""                   REM sends ("a")
program """a b"""                 REM sends ("a) and (b")
program """"Hello,""" Mike said." REM sends ("Hello," Mike said.)
program ""a""b""c""d""            REM sends (abcd) since the "" groups wrap nothing
program "hello to """quotes""     REM sends (hello to "quotes")
program """"hello world""         REM sends ("hello world")
program """hello" world""         REM sends ("hello world")
program """hello "world""         REM sends ("hello) and (world")
program "hello ""world"""         REM sends (hello "world")
program "hello """world""         REM sends (hello "world")

Final note: I did not read any of this from any tutorial - I came up with all of it by experimenting. Therefore, my explanation may not be true internally. Nonetheless all the examples above evaluate as given, thus validating (but not proving) my theory.

I tested this on Windows 7, 64bit using only *.exe calls with parameter passing (not *.bat, but I would suppose it works the same).

I too faced this error while importing an 8GB sql database file. Checked my mysql installation drive. There was no space left in the drive. So got some space by removing unwanted items and re-ran my database import command. This time it was successful.

Another idea could be creating a dark blurred pseudo element eventually with transparency to imitate shadow. Make it with slightly less height and more width i.g.

Since every control element gets referenced with its name on the form element (see forms specs), controls with name "submit" will override the build-in submit function.

Which leads to the error mentioned in comments above:

Uncaught TypeError: Property 'submit' of object #<HTMLFormElement> is not a function

As in the accepted answer above the simplest solution would be to change the name of that control element.

However another solution could be to use dispatchEvent method on form element:

$("#form_id")[0].dispatchEvent(new Event('submit')); 

the mysqli_queryexcepts 2 parameters , first variable is mysqli_connectequivalent variable , second one is the query you have provided

$name1 = mysqli_connect(localhost,tdoylex1_dork,dorkk,tdoylex1_dork);

$name2 = mysqli_query($name1,"SELECT name FROM users ORDER BY RAND() LIMIT 1");

Vanilla js with support for Shift + Enter and ability to choose which HTML tags are focusable. Should work IE9+.

  onKeyUp(e) {
    switch (e.keyCode) {
      case 13: //Enter
        var focusableElements = document.querySelectorAll('input, button')
        var index = Array.prototype.indexOf.call(focusableElements, document.activeElement)
        if(e.shiftKey)
          focus(focusableElements, index - 1)
        else
          focus(focusableElements, index + 1)

        e.preventDefault()
        break;
    }
    function focus(elements, index) {
      if(elements[index])
        elements[index].focus()
    }
  }

On Ubuntu systems, use the following locations:

1. System-wide persistent variables in the format of JAVA_PATH=/usr/local/java store in

   /etc/environment
   

2. System-wide persistent variables that reference variables such as
   export PATH="$JAVA_PATH:$PATH" store in

   /etc/.bashrc
   

3. User specific persistent variables in the format of PATH DEFAULT=/usr/bin:usr/local/bin store in

   ~/.pam_environment

I just want to add a small detail concerning lastInsertId();

When entering more than one row at the time, it does not return the last Id, but the first Id of the collection of last inserts.

Consider the following example

$sql = 'INSERT INTO my_table (varNumb,userid) VALUES
     (1, :userid),
     (2, :userid)';
$sql->addNewNames = $db->prepare($sql);
addNewNames->execute(array(':userid' => $userid));

echo $db->lastInsertId();

What happens here is that I push in my_table two new rows. The id of the table is auto-increment. Here, for the same user, I add two rows with a different varNumb.

The echoed value at the end will be equal to the id of the row where varNumb=1, which means not the id of the last row, but the id of the first row that was added in the last request.

Have you actually downloaded and installed one of the milestone builds from https://jdk7.dev.java.net/ ?

You can have a play with the features, though it's not stable so you shouldn't be releasing software against them.

Use this:

find . -type f -print0 | tar -czvf backup.tar.gz --null -T -

It will:

• deal with files with spaces, newlines, leading dashes, and other funniness
• handle an unlimited number of files
• won't repeatedly overwrite your backup.tar.gz like using tar -c with xargs will do when you have a large number of files

Also see:

• GNU tar manual
• How can I build a tar from stdin?, search for null

I just wanted to be able to run:

$ rake some:task arg1 arg2

Simple, right? (Nope!)

Rake interprets arg1 and arg2 as tasks, and tries to run them. So we just abort before it does.

namespace :some do
  task task: :environment do
    arg1, arg2 = ARGV

    # your task...

    exit
  end
end

Take that, brackets!

Disclaimer: I wanted to be able to do this in a pretty small pet project. Not intended for "real world" usage since you lose the ability to chain rake tasks (i.e. rake task1 task2 task3). IMO not worth it. Just use the ugly rake task[arg1,arg2].

Although the accepted answer is still correct about needing to match directories with package names, you really need to migrate to using Go modules instead of using GOPATH. New users who encounter this problem may be confused about the mentions of using GOPATH (as was I), which are now outdated. So, I will try to clear up this issue and provide guidance associated with preventing this issue when using Go modules.

If you're already familiar with Go modules and are experiencing this issue, skip down to my more specific sections below that cover some of the Go conventions that are easy to overlook or forget.

This guide teaches about Go modules: https://golang.org/doc/code.html

Project organization with Go modules

Once you migrate to Go modules, as mentioned in that article, organize the project code as described:

A repository contains one or more modules. A module is a collection of related Go packages that are released together. A Go repository typically contains only one module, located at the root of the repository. A file named go.mod there declares the module path: the import path prefix for all packages within the module. The module contains the packages in the directory containing its go.mod file as well as subdirectories of that directory, up to the next subdirectory containing another go.mod file (if any).

Each module's path not only serves as an import path prefix for its packages, but also indicates where the go command should look to download it. For example, in order to download the module golang.org/x/tools, the go command would consult the repository indicated by https://golang.org/x/tools (described more here).

An import path is a string used to import a package. A package's import path is its module path joined with its subdirectory within the module. For example, the module github.com/google/go-cmp contains a package in the directory cmp/. That package's import path is github.com/google/go-cmp/cmp. Packages in the standard library do not have a module path prefix.

You can initialize your module like this:

$ go mod init github.com/mitchell/foo-app

Your code doesn't need to be located on github.com for it to build. However, it's a best practice to structure your modules as if they will eventually be published.

Understanding what happens when trying to get a package

There's a great article here that talks about what happens when you try to get a package or module: https://medium.com/rungo/anatomy-of-modules-in-go-c8274d215c16 It discusses where the package is stored and will help you understand why you might be getting this error if you're already using Go modules.

Ensure the imported function has been exported

Note that if you're having trouble accessing a function from another file, you need to ensure that you've exported your function. As described in the first link I provided, a function must begin with an upper-case letter to be exported and made available for importing into other packages.

Names of directories

Another critical detail (as was mentioned in the accepted answer) is that names of directories are what define the names of your packages. (Your package names need to match their directory names.) You can see examples of this here: https://medium.com/rungo/everything-you-need-to-know-about-packages-in-go-b8bac62b74cc With that said, the file containing your main method (i.e., the entry point of your application) is sort of exempt from this requirement.

As an example, I had problems with my imports when using a structure like this:

/my-app
+-- go.mod
+-- /src
   +-- main.go
   +-- /utils
      +-- utils.go

I was unable to import the code in utils into my main package.

However, once I put main.go into its own subdirectory, as shown below, my imports worked just fine:

/my-app
+-- go.mod
+-- /src
   +-- /app
   |  +-- main.go
   +-- /utils
      +-- utils.go

In that example, my go.mod file looks like this:

module git.mydomain.com/path/to/repo/my-app

go 1.14

When I saved main.go after adding a reference to utils.MyFunction(), my IDE automatically pulled in the reference to my package like this:

import "git.mydomain.com/path/to/repo/my-app/src/my-app"

(I'm using VS Code with the Golang extension.)

Notice that the import path included the subdirectory to the package.

Dealing with a private repo

If the code is part of a private repo, you need to run a git command to enable access. Otherwise, you can encounter other errors This article mentions how to do that for private Github, BitBucket, and GitLab repos: https://medium.com/cloud-native-the-gathering/go-modules-with-private-git-repositories-dfe795068db4 This issue is also discussed here: What's the proper way to "go get" a private repository?

As they say, the devil is in the details...

The biggest difference between the two methods of collection enumeration is that foreach carries state, whereas ForEach(x => { }) does not.

But lets dig a little deeper, because there are some things you should be aware of that can influence your decision, and there are some caveats you should be aware of when coding for either case.

Lets use List<T> in our little experiment to observe behavior. For this experiment, I am using .NET 4.7.2:

var names = new List<string>
{
    "Henry",
    "Shirley",
    "Ann",
    "Peter",
    "Nancy"
};

Lets iterate over this with foreach first:

foreach (var name in names)
{
    Console.WriteLine(name);
}

We could expand this into:

using (var enumerator = names.GetEnumerator())
{

}

With the enumerator in hand, looking under the covers we get:

public List<T>.Enumerator GetEnumerator()
{
  return new List<T>.Enumerator(this);
}
    internal Enumerator(List<T> list)
{
  this.list = list;
  this.index = 0;
  this.version = list._version;
  this.current = default (T);
}

public bool MoveNext()
{
  List<T> list = this.list;
  if (this.version != list._version || (uint) this.index >= (uint) list._size)
    return this.MoveNextRare();
  this.current = list._items[this.index];
  ++this.index;
  return true;
}

object IEnumerator.Current
{
  {
    if (this.index == 0 || this.index == this.list._size + 1)
      ThrowHelper.ThrowInvalidOperationException(ExceptionResource.InvalidOperation_EnumOpCantHappen);
    return (object) this.Current;
  }
}

Two things become immediate evident:

1. We are returned a stateful object with intimate knowledge of the underlying collection.
2. The copy of the collection is a shallow copy.

This is of course in no way thread safe. As was pointed out above, changing the collection while iterating is just bad mojo.

But what about the problem of the collection becoming invalid during iteration by means outside of us mucking with the collection during iteration? Best practices suggests versioning the collection during operations and iteration, and checking versions to detect when the underlying collection changes.

Here's where things get really murky. According to the Microsoft documentation:

If changes are made to the collection, such as adding, modifying, or deleting elements, the behavior of the enumerator is undefined.

Well, what does that mean? By way of example, just because List<T> implements exception handling does not mean that all collections that implement IList<T> will do the same. That seems to be a clear violation of the Liskov Substitution Principle:

Objects of a superclass shall be replaceable with objects of its subclasses without breaking the application.

Another problem is that the enumerator must implement IDisposable -- that means another source of potential memory leaks, not only if the caller gets it wrong, but if the author does not implement the Dispose pattern correctly.

Lastly, we have a lifetime issue... what happens if the iterator is valid, but the underlying collection is gone? We now a snapshot of what was... when you separate the lifetime of a collection and its iterators, you are asking for trouble.

Lets now examine ForEach(x => { }):

names.ForEach(name =>
{

});

This expands to:

public void ForEach(Action<T> action)
{
  if (action == null)
    ThrowHelper.ThrowArgumentNullException(ExceptionArgument.match);
  int version = this._version;
  for (int index = 0; index < this._size && (version == this._version || !BinaryCompatibility.TargetsAtLeast_Desktop_V4_5); ++index)
    action(this._items[index]);
  if (version == this._version || !BinaryCompatibility.TargetsAtLeast_Desktop_V4_5)
    return;
  ThrowHelper.ThrowInvalidOperationException(ExceptionResource.InvalidOperation_EnumFailedVersion);
}

Of important note is the following:

for (int index = 0; index < this._size && ... ; ++index) action(this._items[index]);

This code does not allocate any enumerators (nothing to Dispose), and does not pause while iterating.

Note that this also performs a shallow copy of the underlying collection, but the collection is now a snapshot in time. If the author does not correctly implement a check for the collection changing or going 'stale', the snapshot is still valid.

This doesn't in any way protect you from the problem of the lifetime issues... if the underlying collection disappears, you now have a shallow copy that points to what was... but at least you don't have a Dispose problem to deal with on orphaned iterators...

Yes, I said iterators... sometimes its advantageous to have state. Suppose you want to maintain something akin to a database cursor... maybe multiple foreach style Iterator<T>'s is the way to go. I personally dislike this style of design as there are too many lifetime issues, and you rely on the good graces of the authors of the collections you are relying on (unless you literally write everything yourself from scratch).

There is always a third option...

for (var i = 0; i < names.Count; i++)
{
    Console.WriteLine(names[i]);
}

It ain't sexy, but its got teeth (apologies to Tom Cruise and the movie The Firm)

Its your choice, but now you know and it can be an informed one.

Your output is correct. Denote the white characters of " Hello" and " This" at the beginning.

Another issue is with your methodology. Use the Arrays.sort() method:

String[] strings = { " Hello ", " This ", "Is ", "Sorting ", "Example" };
Arrays.sort(strings);

Output:

 Hello
 This
Example
Is
Sorting

Here the third element of the array "is" should be "Is", otherwise it will come in last after sorting. Because the sort method internally uses the ASCII value to sort elements.

When you create a cookie via PHP die Default Value is 0, from the manual:

If set to 0, or omitted, the cookie will expire at the end of the session (when the browser closes)

Otherwise you can set the cookies lifetime in seconds as the third parameter:

http://www.php.net/manual/en/function.setcookie.php

But if you mean to get the remaining lifetime of an already existing cookie, i fear that, is not possible (at least not in a direct way).

There are several snippets here. However, this one is compact, efficient, and C++11 friendly:

static std::string base64_encode(const std::string &in) {

    std::string out;

    int val = 0, valb = -6;
    for (uchar c : in) {
        val = (val << 8) + c;
        valb += 8;
        while (valb >= 0) {
            out.push_back("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"[(val>>valb)&0x3F]);
            valb -= 6;
        }
    }
    if (valb>-6) out.push_back("ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"[((val<<8)>>(valb+8))&0x3F]);
    while (out.size()%4) out.push_back('=');
    return out;
}

static std::string base64_decode(const std::string &in) {

    std::string out;

    std::vector<int> T(256,-1);
    for (int i=0; i<64; i++) T["ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"[i]] = i;

    int val=0, valb=-8;
    for (uchar c : in) {
        if (T[c] == -1) break;
        val = (val << 6) + T[c];
        valb += 6;
        if (valb >= 0) {
            out.push_back(char((val>>valb)&0xFF));
            valb -= 8;
        }
    }
    return out;
}

If you invoke addRecipient multiple times it will add the given recipient to the list of recipients of the given time (TO, CC, BCC)

For example:

message.addRecipient(Message.RecipientType.CC, InternetAddress.parse("[email protected]"));
message.addRecipient(Message.RecipientType.CC, InternetAddress.parse("[email protected]"));
message.addRecipient(Message.RecipientType.CC, InternetAddress.parse("[email protected]"));

Will add the 3 addresses to CC

If you wish to add all addresses at once you should use setRecipients or addRecipients and provide it with an array of addresses

Address[] cc = new Address[] {InternetAddress.parse("[email protected]"),
                               InternetAddress.parse("[email protected]"), 
                               InternetAddress.parse("[email protected]")};
message.addRecipients(Message.RecipientType.CC, cc);

You can also use InternetAddress.parse to parse a list of addresses

message.addRecipients(Message.RecipientType.CC, 
                      InternetAddress.parse("[email protected],[email protected],[email protected]"));

I implemented the following and it works well. Basically, I set the body dimensions according to the size of the iFrame content. It does mean that our non-iFrame menu can be scrolled off the screen, but otherwise, this makes our sites functional with iPad and iPhone. "workbox" is the ID of our iFrame.

// Configure for scrolling peculiarities of iPad and iPhone

if (navigator.userAgent.indexOf('iPhone') != -1 || navigator.userAgent.indexOf('iPad') != -1)
{
    document.body.style.width = "100%";
    document.body.style.height = "100%";
    $("#workbox").load(function (){ // Wait until iFrame content is loaded before checking dimensions of the content
        iframeWidth = $("#workbox").contents().width();
        if (iframeWidth > 400)
           document.body.style.width = (iframeWidth + 182) + 'px';

        iframeHeight = $("#workbox").contents().height();
        if (iframeHeight>200)
            document.body.style.height = iframeHeight + 'px';
     });
}

You can use the slurp module to fetch a file from the remote host: (Thanks to @mlissner for suggesting it)

vars:
  amazon_linux_ami: "ami-fb8e9292"
  user_data_file: "base-ami-userdata.sh"
tasks:
- name: Load data
  slurp:
    src: "{{ user_data_file }}"
  register: slurped_user_data
- name: Decode data and store as fact # You can skip this if you want to use the right hand side directly...
  set_fact:
    user_data: "{{ slurped_user_data.content | b64decode }}"

Combining @Joachim's with the above, you could use

next(iter(my_list[index:index+1]), default)

Examples:

next(iter(range(10)[8:9]), 11)
8
>>> next(iter(range(10)[12:13]), 11)
11

Or, maybe more clear, but without the len

my_list[index] if my_list[index:index + 1] else default

Using the div trick with tab_index="0" or tabIndex="-1" works, but any time the user is focusing a view that's not an element, you get an ugly focus-outline on the entire website. This can be fixed by setting the CSS for the div to use outline: none in the focus.

Here's the implementation with styled components:

import styled from "styled-components"

const KeyReceiver = styled.div`
  &:focus {
    outline: none;
  }
`

and in the App class:

  render() {
    return (      
      <KeyReceiver onKeyDown={this.handleKeyPress} tabIndex={-1}>
          Display stuff...
      </KeyReceiver>
    )

Sounds like you need to add the formatting to the WHERE:

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
FROM users 
WHERE DATE_FORMAT(users.signup_date, '%Y-%m-%d') = CURDATE()

See SQL Fiddle with Demo

I had two charts.

<div id="barChart"></div>
<div id="bubbleChart"></div>

This removed all charts.

d3.select("svg").remove(); 

This worked for removing the existing bar chart, but then I couldn't re-add the bar chart after

d3.select("#barChart").remove();

Tried this. It not only let me remove the existing bar chart, but also let me re-add a new bar chart.

d3.select("#barChart").select("svg").remove();

var svg = d3.select('#barChart')
       .append('svg')
       .attr('width', width + margins.left + margins.right)
       .attr('height', height + margins.top + margins.bottom)
       .append('g')
       .attr('transform', 'translate(' + margins.left + ',' + margins.top + ')');

Not sure if this is the correct way to remove, and re-add a chart in d3. It worked in Chrome, but have not tested in IE.

You could use ReverseListIterator from Apache Commons-Collections:

https://commons.apache.org/proper/commons-collections/apidocs/org/apache/commons/collections4/iterators/ReverseListIterator.html

If you use jQuery, u can do it like this:

<form action="example" method="post" id="loginform">
  ...
  <input id="btnin" type="button" value="login"/>
  <input id="btnreg" type="button" value="regist"/>
</form>

And js will be:

$("#btnin").click(function(){
   $("#loginform").attr("action", "user_login");
   $("#loginform").submit();
}
$("#btnreg").click(function(){
   $("#loginform").attr("action", "user_regist");
   $("#loginform").submit();
}

Give this CSS class to the targeted <div>:

.centered {_x000D_
  width: 150px;_x000D_
  height: 150px;_x000D_
  display: flex;_x000D_
  align-items: center;_x000D_
  justify-content: center;_x000D_
  text-align: center;_x000D_
  background: red; /* Not necessary just to see the result clearly */_x000D_
}

<div class="centered">This text is centered horizontally and vertically</div>

OK, I know at first might be a bit confusing, but display is talking about the parent element, so means when we say: display: flex;, it's about the element and when we say display:inline-flex;, is also making the element itself inline...

It's like make a div inline or block, run the snippet below and you can see how display flex breaks down to next line:

.inline-flex {_x000D_
  display: inline-flex;_x000D_
}_x000D_
_x000D_
.flex {_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
p {_x000D_
  color: red;_x000D_
}

<body>_x000D_
  <p>Display Inline Flex</p>_x000D_
  <div class="inline-flex">_x000D_

A simple and up to date solution is to use the React React useRef hook that stores a reference to the component/element, combined with a useEffect hook, which fires at component renders.

import React, {useState, useEffect, useRef} from 'react';

export default App = () => {
  const [width, setWidth] = useState(0);
  const elementRef = useRef(null);

  useEffect(() => {
    setWidth(elementRef.current.getBoundingClientRect().width);
  }, []); //empty dependency array so it only runs once at render

  return (
    <div ref={elementRef}>
      {width}
    </div>
  )
}

"Is it possible to run this service always as when the application pause and anything else?"

Yes.

1. In the service onStartCommand method return START_STICKY.

   public int onStartCommand(Intent intent, int flags, int startId) {
           return START_STICKY;
   }
   

2. Start the service in the background using startService(MyService) so that it always stays active regardless of the number of bound clients.

   Intent intent = new Intent(this, PowerMeterService.class);
   startService(intent);
   

3. Create the binder.

   public class MyBinder extends Binder {
           public MyService getService() {
                   return MyService.this;
           }
   }
   

4. Define a service connection.

   private ServiceConnection m_serviceConnection = new ServiceConnection() {
           public void onServiceConnected(ComponentName className, IBinder service) {
                   m_service = ((MyService.MyBinder)service).getService();
           }
   
           public void onServiceDisconnected(ComponentName className) {
                   m_service = null;
           }
   };
   

5. Bind to the service using bindService.

           Intent intent = new Intent(this, MyService.class);
           bindService(intent, m_serviceConnection, BIND_AUTO_CREATE);
   

6. For your service you may want a notification to launch the appropriate activity once it has been closed.

   private void addNotification() {
           // create the notification
           Notification.Builder m_notificationBuilder = new Notification.Builder(this)
                   .setContentTitle(getText(R.string.service_name))
                   .setContentText(getResources().getText(R.string.service_status_monitor))
                   .setSmallIcon(R.drawable.notification_small_icon);
   
           // create the pending intent and add to the notification
           Intent intent = new Intent(this, MyService.class);
           PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
           m_notificationBuilder.setContentIntent(pendingIntent);
   
           // send the notification
           m_notificationManager.notify(NOTIFICATION_ID, m_notificationBuilder.build());
   }
   

7. You need to modify the manifest to launch the activity in single top mode.

             android:launchMode="singleTop"
   

8. Note that if the system needs the resources and your service is not very active it may be killed. If this is unacceptable bring the service to the foreground using startForeground.

           startForeground(NOTIFICATION_ID, m_notificationBuilder.build());
   

You can generate a series of date between two dates using the pandas library simply and trustfully

import pandas as pd

print pd.date_range(start='1/1/2010', end='1/08/2018', freq='M')

You can change the frequency of generating dates by setting freq as D, M, Q, Y (daily, monthly, quarterly, yearly )

I had to add:

secureTextEntry={true}

Along with

password={true}

I've been experiencing this annoying problem with PG for years. I created this gist to help.

The following command always work for me.

# Substitute Postgres.app/Contents/Versions/9.5 with appropriate version number
sudo ARCHFLAGS="-arch x86_64" gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.5/bin/pg_config

Can try this too!
Create a dictionary of replacement values.

import pandas as pd
data = pd.DataFrame([[1,0],[0,1],[1,0],[0,1]], columns=["sex", "split"])

replace_dict= {0:'Female',1:'Male'}
print(replace_dict)

Use the map function for replacing values

data['sex']=data['sex'].map(replace_dict)

Output after replacing

From here - Remember:

<input v-model="something">

is essentially the same as:

<input
   v-bind:value="something"
   v-on:input="something = $event.target.value"
>

or (shorthand syntax):

<input
   :value="something"
   @input="something = $event.target.value"
>

So v-model is a two-way binding for form inputs. It combines v-bind, which brings a js value into the markup, and v-on:input to update the js value.

Use v-model when you can. Use v-bind/v-on when you must :-) I hope your answer was accepted.

v-model works with all the basic HTML input types (text, textarea, number, radio, checkbox, select). You can use v-model with input type=date if your model stores dates as ISO strings (yyyy-mm-dd). If you want to use date objects in your model (a good idea as soon as you're going to manipulate or format them), do this.

v-model has some extra smarts that it's good to be aware of. If you're using an IME ( lots of mobile keyboards, or Chinese/Japanese/Korean ), v-model will not update until a word is complete (a space is entered or the user leaves the field). v-input will fire much more frequently.

v-model also has modifiers .lazy, .trim, .number, covered in the doc.

FOR XML PATH might not work on Microsoft Azure Synapse Serve. A possible alternative, following @Taryn dynamic generated cols approach, same results is obtained by using STRING_AGG.

DECLARE @cols AS NVARCHAR(MAX), @query AS NVARCHAR(MAX)

SELECT @cols = STRING_AGG(QUOTENAME(c.phaseid),', ')
/*OPTIONAL: within group (order by cast(t1.[FLOW_SP_SLPM] as INT) asc)*/
FROM (SELECT phaseid FROM temp
GROUP BY phaseid) c

set @query = 'SELECT elementid,' + @cols + ' from 
             (
                select elementid,
                phaseid,
                effort
                from temp
            ) x
            PIVOT 
            (
                max(effort)
                for phaseid in (' + @cols + ')
            ) p '

execute(@query)

I also had this problem. it was weird that it worked on my lollipop emulator, but not on my actual kitkat device.

Android Studio will now force you to write the permission upper case, and that's the problem.

Add

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

Above the application tab and it will work.

One small addition to the answer by vasekt:

The provided solution with the SocketFactoryRegistry works when using PoolingHttpClientConnectionManager.

However, connections via plain http don't work any longer then. You have to add a PlainConnectionSocketFactory for the http protocol additionally to make them work again:

Registry<ConnectionSocketFactory> socketFactoryRegistry = 
  RegistryBuilder.<ConnectionSocketFactory> create()
  .register("https", sslsf)
  .register("http", new PlainConnectionSocketFactory()).build();

You can set proxies using environment variables.

import os
os.environ['http_proxy'] = '127.0.0.1'
os.environ['https_proxy'] = '127.0.0.1'

urllib2 will add proxy handlers automatically this way. You need to set proxies for different protocols separately otherwise they will fail (in terms of not going through proxy), see below.

For example:

proxy = urllib2.ProxyHandler({'http': '127.0.0.1'})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
urllib2.urlopen('http://www.google.com')
# next line will fail (will not go through the proxy) (https)
urllib2.urlopen('https://www.google.com')

Instead

proxy = urllib2.ProxyHandler({
    'http': '127.0.0.1',
    'https': '127.0.0.1'
})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
# this way both http and https requests go through the proxy
urllib2.urlopen('http://www.google.com')
urllib2.urlopen('https://www.google.com')

You should be able to just look at .Keys:

    Dictionary<string, int> data = new Dictionary<string, int>();
    data.Add("abc", 123);
    data.Add("def", 456);
    foreach (string key in data.Keys)
    {
        Console.WriteLine(key);
    }

This is what I ended up doing:

var ItemSchema = new Schema({
    name    : { type: String, required: true, trim: true }
  , created_at    : { type: Date }
  , updated_at    : { type: Date }
});


ItemSchema.pre('save', function(next){
  now = new Date();
  this.updated_at = now;
  if ( !this.created_at ) {
    this.created_at = now;
  }
  next();
});

Eclipse uses the default Java on the system to run itself. This can also be changed in the eclipse.ini file in your eclipse install folder.

To find out the version of java that your eclipse project is using, see Project->properties->build path->Libraries tab and see the JRE system library thats being used. You can also check it out at Window->Preferences->Java->Installed JREs. This is a list of all JREs that eclipse knows about

To find out using code, use the System.getProperty(...) method. See http://java.sun.com/j2se/1.5.0/docs/api/java/lang/System.html#getProperties() for supported properties.

Go to the DBMS Output window (View->DBMS Output).

I know you've found another solution, but for those like me who find this question, looking for the same thing, it can be achieved with requests as follows:

Firstly, as Marcus did, check the source of the login form to get three pieces of information - the url that the form posts to, and the name attributes of the username and password fields. In his example, they are inUserName and inUserPass.

Once you've got that, you can use a requests.Session() instance to make a post request to the login url with your login details as a payload. Making requests from a session instance is essentially the same as using requests normally, it simply adds persistence, allowing you to store and use cookies etc.

Assuming your login attempt was successful, you can simply use the session instance to make further requests to the site. The cookie that identifies you will be used to authorise the requests.

Example

import requests

# Fill in your details here to be posted to the login form.
payload = {
    'inUserName': 'username',
    'inUserPass': 'password'
}

# Use 'with' to ensure the session context is closed after use.
with requests.Session() as s:
    p = s.post('LOGIN_URL', data=payload)
    # print the html returned or something more intelligent to see if it's a successful login page.
    print p.text

    # An authorised request.
    r = s.get('A protected web page url')
    print r.text
        # etc...

Answer for Python beginners

In simpler words:

1. The key= parameter of sort requires a key function (to be applied to be objects to be sorted) rather than a single key value and
2. that is just what operator.itemgetter(1) will give you: A function that grabs the first item from a list-like object.

(More precisely those are callables, not functions, but that is a difference that can often be ignored.)

A mutable dictionary can be changed, i.e. you can add and remove objects. An immutable is fixed once it is created.

create and add:

NSMutableDictionary *dict = [[NSMutableDictionary alloc]initWithCapacity:10];
[dict setObject:[NSNumber numberWithInt:42] forKey:@"A cool number"];

and retrieve:

int myNumber = [[dict objectForKey:@"A cool number"] intValue];

Pip 10.0.* doesn't support main.

You have to downgrade to pip 9.0.3.

I'm not really sure of the syntax {el => this.inputEntry = el}, but when clearing an input field you assign a ref like you mentioned.

<input type="text" ref="someName" />

Then in the onClick function after you've finished using the input value, just use...

this.refs.someName.value = '';

Edit

Actually the {el => this.inputEntry = el} is the same as this I believe. Maybe someone can correct me. The value for el must be getting passed in from somewhere, to act as the reference.

function (el) {
    this.inputEntry = el;
}

restart: on-failure did the trick for me..see below

Add the Access-Control-Allow-Origin header from the server

Access-Control-Allow-Origin: https://www.mysite.com

http://en.wikipedia.org/wiki/Cross-Origin_Resource_Sharing

Change the type to submit and give it a name (and remove the useless onclick and flat out the 90's style uppercased tags/attributes).

<input type="submit" name="foo" value="A" />
<input type="submit" name="foo" value="B" />
...

The value will be available by $_POST['foo'] (if the parent <form> has a method="post").

var first_number = parseInt(document.getElementById("Text1").value);
var second_number = parseInt(document.getElementById("Text2").value);

// This is because your method .getElementById has the letter 's': .getElement**s**ById

Now with HikcariCp as default connection pooling with new version of spring boot.It can be directly done as shown below.

@Configuration
public class PurchaseOrderDbConfig {
    
    @Bean
    @ConfigurationProperties(prefix = "com.sysco.purchaseorder.datasoure")
    public DataSource dataSource() {
        return DataSourceBuilder.create().build();
    }

}

application.yml

com:
  sysco:
    purchaseorder:
      datasoure:
        driverClassName: com.mysql.jdbc.Driver
        jdbcUrl: jdbc:mysql://localhost:3306/purchaseorder
        username: root
        password: root123
        idleTimeout: 600000

If you will print the value of idle timeout value

ApplicationContext context=SpringApplication.run(ApiBluePrint.class, args);
   HikariDataSource dataSource=(HikariDataSource) context.getBean(DataSource.class);
   System.out.println(dataSource.getIdleTimeout());

you will get value as 600000 where as default value is 300000 if you dont define any custom value

Documentation of Math.round says:

Returns the result of rounding the argument to an integer. The result is equivalent to (int) Math.floor(f+0.5).

No need to cast to int. Maybe it was changed from the past.

Check out my highly simplified Echo example: It is designed to use basic HTTP communication, but it can easily be modified to use named pipes by editing the app.config files for the client and server. Make the following changes:

Edit the server's app.config file, removing or commenting out the http baseAddress entry and adding a new baseAddress entry for the named pipe (called net.pipe). Also, if you don't intend on using HTTP for a communication protocol, make sure the serviceMetadata and serviceDebug is either commented out or deleted:

<configuration>
    <system.serviceModel>
        <services>
            <service name="com.aschneider.examples.wcf.services.EchoService">
                <host>
                    <baseAddresses>
                        <add baseAddress="net.pipe://localhost/EchoService"/>
                    </baseAddresses>
                </host>
            </service>
        </services>
        <behaviors>
            <serviceBehaviors></serviceBehaviors>
        </behaviors>
    </system.serviceModel>
</configuration>

Edit the client's app.config file so that the basicHttpBinding is either commented out or deleted and a netNamedPipeBinding entry is added. You will also need to change the endpoint entry to use the pipe:

<configuration>
    <system.serviceModel>
        <bindings>
            <netNamedPipeBinding>
                <binding name="NetNamedPipeBinding_IEchoService"/>
            </netNamedPipeBinding>
        </bindings>
        <client>
            <endpoint address              = "net.pipe://localhost/EchoService"
                      binding              = "netNamedPipeBinding"
                      bindingConfiguration = "NetNamedPipeBinding_IEchoService"
                      contract             = "EchoServiceReference.IEchoService"
                      name                 = "NetNamedPipeBinding_IEchoService"/>
        </client>
    </system.serviceModel>
</configuration>

The above example will only run with named pipes, but nothing is stopping you from using multiple protocols to run your service. AFAIK, you should be able to have a server run a service using both named pipes and HTTP (as well as other protocols).

Also, the binding in the client's app.config file is highly simplified. There are many different parameters you can adjust, aside from just specifying the baseAddress...

The option that I tend to use, mostly because it's simple and I don't have to think, is using Write-Output as below. Write-Output will put an EOL marker in the string for you and you can simply output the finished string.

Write-Output $stringThatNeedsEOLMarker | Out-File -FilePath PathToFile -Append

Alternatively, you could also just build the entire string using Write-Output and then push the finished string into Out-File.

you can use the weight value specified in the Google Fonts.

body{
 font-family: 'Heebo', sans-serif;
 font-weight: 100;
}

Instead of the * selector you can use the :not(selector) with the > selector and set something that definitely wont be a child.

Edit: I thought it would be faster but it turns out I was wrong. Disregard.

Example:

.container > :not(marquee){
        color:red;
    }


<div class="container">
    <p></p>
    <span></span>
<div>

change

});


$(document).ready(function () {
    $('.smallTabsHeader a').pluginbutton();
});

to

})(jQuery); //<-- ADD THIS


$(document).ready(function () {
    $('.smallTabsHeader a').pluginbutton();
});

This is needed because, you need to call the anonymous function that you created with

(function($){

and notice that it expects an argument that it will use internally as $, so you need to pass a reference to the jQuery object.

Additionally, you will need to change all the this. to $(this)., except the first one, in which you do return this.each

In the first one (where you do not need the $()) it is because in the plugin body, this holds a reference to the jQuery object matching your selector, but anywhere deeper than that, this refers to the specific DOM element, so you need to wrap it in $().

This has changed for Visual Studio 2012 (I know the original question says VS2010, but the title will still hit on searches).

When you create a VS2012 MVC project, the system.web.mvc is placed in the packages folder which is peer to the solution. This will be referenced in the web project by default and you can find the exact path there).

If you want to reference this in a secondary project (say a supporting .dll with filters or other attributes), then you can reference it from there.

Here is the code snippet which will work for sure. You can visit below link for working jsFiddle and explainantion in detail. How to locate multiple addresses on google maps with perfect zoom

var infowindow = new google.maps.InfoWindow();  
google.maps.event.addListener(marker, 'mouseover', (function(marker) {  
           return function() {  
               var content = address;  
               infowindow.setContent(content);  
               infowindow.open(map, marker);  
           }  
         })(marker));  

I came across this question and thought I would clarify that the lists() method of a eloquent builder object was depreciated in Laravel 5.2 and replaced with pluck().

// <= Laravel 5.1
Word_relation::where('word_one', $word_id)->lists('word_one')->toArray();
// >= Laravel 5.2
Word_relation::where('word_one', $word_id)->pluck('word_one')->toArray();

These methods can also be called on a Collection for example

// <= Laravel 5.1
  $collection = Word_relation::where('word_one', $word_id)->get();
  $array = $collection->lists('word_one');

// >= Laravel 5.2
  $collection = Word_relation::where('word_one', $word_id)->get();
  $array = $collection->pluck('word_one');

You can iterate over the index values if your dataframe has already been created.

df = df.groupby('l_customer_id_i').agg(lambda x: ','.join(x))
for name in df.index:
    print name
    print df.loc[name]

Just for completeness: you may also use array_walk:

array_walk($yourArray, function(&$value)
{
  $value = strtolower($value);
});

From PHP docs:

If callback needs to be working with the actual values of the array, specify the first parameter of callback as a reference. Then, any changes made to those elements will be made in the original array itself.

Or directly via foreach loop using references:

foreach($yourArray as &$value)
  $value = strtolower($value);

Note that these two methods change the array "in place", whereas array_map creates and returns a copy of the array, which may not be desirable in case of very large arrays.

windows:

@echo off
for /r %%d in (*.wav) do (
    ffmpeg -i "%%~nd%%~xd" -codec:a libmp3lame -c:v copy -qscale:a 2 "%

%~nd.2.mp3"
)

this is variable bitrate of quality 2, you can set it to 0 if you want but unless you have a really good speaker system it's worthless imo

Adding processData: false to the $.ajax options will fix this issue.

It's impossible to draw a line on screen that's thinner than one pixel. Try using a more subtle color for the border instead.

Question might be a little dated, but you could simply use AbstractMap.SimpleEntry<> as follows:

private Map<String, AttributeType> mapConfig(
    Map<String, String> input, String prefix) {
       int subLength = prefix.length();
       return input.entrySet()
          .stream()
          .map(e -> new AbstractMap.SimpleEntry<>(
               e.getKey().substring(subLength),
               AttributeType.GetByName(e.getValue()))
          .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));

any other Pair-like value object would work too (ie. ApacheCommons Pair tuple).

I believe some of the respondents of this question have missed the broader implication of the fold function as an abstract tool. Yes, sum can do the same thing for a list of integers, but this is a trivial case. fold is more generic. It is useful when you have a sequence of data structures of varying shape and want to cleanly express an aggregation. So instead of having to build up a for loop with an aggregate variable and manually recompute it each time, a fold function (or the Python version, which reduce appears to correspond to) allows the programmer to express the intent of the aggregation much more plainly by simply providing two things:

• A default starting or "seed" value for the aggregation.
• A function that takes the current value of the aggregation (starting with the "seed") and the next element in the list, and returns the next aggregation value.

Intent chooser = new Intent(Intent.ACTION_GET_CONTENT);
Uri uri = Uri.parse(Environment.getDownloadCacheDirectory().getPath().toString());
chooser.addCategory(Intent.CATEGORY_OPENABLE);
chooser.setDataAndType(uri, "*/*");
// startActivity(chooser);
try {
startActivityForResult(chooser, SELECT_FILE);
}
catch (android.content.ActivityNotFoundException ex)
{
Toast.makeText(this, "Please install a File Manager.",
Toast.LENGTH_SHORT).show();
}

In code above, if setDataAndType is "*/*" a builtin file browser is opened to pick any file, if I set "text/plain" Dropbox is opened. I have Dropbox, Google Drive installed. If I uninstall Dropbox only "*/*" works to open file browser. This is Android 4.4.2. I can download contents from Dropbox and for Google Drive, by getContentResolver().openInputStream(data.getData()).

Use this:

    public void ShowAllPostBackData()
    {
        if (IsPostBack)
        {
            string[] keys = Request.Form.AllKeys;
            Literal ctlAllPostbackData = new Literal();
            ctlAllPostbackData.Text = "<div class='well well-lg' style='border:1px solid black;z-index:99999;position:absolute;'><h3>All postback data:</h3><br />";
            for (int i = 0; i < keys.Length; i++)
            {
                ctlAllPostbackData.Text += "<b>" + keys[i] + "</b>: " + Request[keys[i]] + "<br />";
            }
            ctlAllPostbackData.Text += "</div>";
            this.Controls.Add(ctlAllPostbackData);
        }
    }

Unfortunately, this is one of the many misnomers in the framework, or at best a violation of SRP.

To use the DateTimePicker for times, set the Format property to either Time or Custom (Use Custom if you want to control the format of the time using the CustomFormat property). Then set the ShowUpDown property to true.

Although a user may set the date and time together manually, they cannot use the GUI to set both.

If your compiler is GCC you can also use following syntax:

int array[256] = {[0 ... 255] = 0};

Please look at http://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Designated-Inits.html#Designated-Inits, and note that this is a compiler-specific feature.

Although ANSI C does not have this mechanism, it is possible to use itoa() as a shortcut:

  char buffer [33];
  itoa (i,buffer,2);
  printf ("binary: %s\n",buffer);

Here's the origin:

itoa in cplusplus reference

It is non-standard C, but K&R mentioned the implementation in the C book, so it should be quite common. It should be in stdlib.h.

httpbin.org uses this method:

return jsonify(origin=request.headers.get('X-Forwarded-For', request.remote_addr))

Final(?) edit

Answer, wrapped up in a function, with annotated interactive session:

>>> import re
>>> def special_match(strg, search=re.compile(r'[^a-z0-9.]').search):
...     return not bool(search(strg))
...
>>> special_match("")
True
>>> special_match("az09.")
True
>>> special_match("az09.\n")
False
# The above test case is to catch out any attempt to use re.match()
# with a `$` instead of `\Z` -- see point (6) below.
>>> special_match("az09.#")
False
>>> special_match("az09.X")
False
>>>

Note: There is a comparison with using re.match() further down in this answer. Further timings show that match() would win with much longer strings; match() seems to have a much larger overhead than search() when the final answer is True; this is puzzling (perhaps it's the cost of returning a MatchObject instead of None) and may warrant further rummaging.

==== Earlier text ====

The [previously] accepted answer could use a few improvements:

(1) Presentation gives the appearance of being the result of an interactive Python session:

reg=re.compile('^[a-z0-9\.]+$')
>>>reg.match('jsdlfjdsf12324..3432jsdflsdf')
True

but match() doesn't return True

(2) For use with match(), the ^ at the start of the pattern is redundant, and appears to be slightly slower than the same pattern without the ^

(3) Should foster the use of raw string automatically unthinkingly for any re pattern

(4) The backslash in front of the dot/period is redundant

(5) Slower than the OP's code!

I think you have to go for

$arrayname[indexname] = $value;

[^] ( within [ ] ) is negation in regular expression whereas ^ is "begining of string"

[^a-z] matches any single character that is not from "a" to "z"

^[a-z] means string starts with from "a" to "z"

I solved this Issue by enabling virtualization technology from system Settings.

Just followed these steps

• Restart my Computer
• Continuously press Esc and then F10 to enter BIOS setup
• configuration
• Check Virtualization technology

Your system settings may be changed According to your Computer. You can google (how to enable virtualizatino for YOUR_PC_NAME).

I hope it helps.

If you just want to display storage (disk) path use this:

Storage::disk('local')->url('screenshots/1.jpg'); // storage/screenshots/1.jpg
Storage::disk('local')->url(''): // storage

Also, if you are interested, I created a package (https://github.com/fsasvari/laravel-uploadify) just for Laravel so you can use all those fields on Eloquent model fields:

$car = Car::first();

$car->upload_cover_image->url();
$car->upload_cover_image->name();
$car->upload_cover_image->basename();
$car->upload_cover_image->extension();
$car->upload_cover_image->filesize();

CREATE OR REPLACE PROCEDURE insert_into (
   p_errcode        OUT   NUMBER,
   p_errmesg        OUT   VARCHAR2,
   p_rowsaffected   OUT   INTEGER
)
AS
   v_param0   VARCHAR2 (30) := '0.25,2.25,33.689, abc, 99';
   v_param1   VARCHAR2 (30) := '2.65,66.32, abc-def, 21.5';
BEGIN
   FOR i IN (SELECT COLUMN_VALUE
               FROM TABLE (SPLIT (v_param0, ',')))
   LOOP
      INSERT INTO tempo
                  (col1
                  )
           VALUES (i.COLUMN_VALUE
                  );
   END LOOP;

   FOR i IN (SELECT COLUMN_VALUE
               FROM TABLE (SPLIT (v_param1, ',')))
   LOOP
      INSERT INTO tempo
                  (col2
                  )
           VALUES (i.COLUMN_VALUE
                  );
   END LOOP;

Just wanted to put an update. page-break-after is a legacy property now.

Official page states

This property has been replaced by the break-after property.

Why don't you just do this

<a href="yoururl.html"><div>...</div></a>

That should work fine and will prompt the "clickable item" cursor change, which the aforementioned solution will not do.

Are you sure you want to do this? In essence, you're duplicating the data that is in the three original columns. From that point on, you'll need to make sure that the data in the combined field matches the data in the first three columns. This is more overhead for your application, and other processes that update the system will need to understand the relationship.

If you need the data, why not select in when you need it? The SQL for selecting what would be in that field would be:

SELECT CONCAT(zipcode, ' - ', city, ', ', state) FROM Table;

This way, if the data in the fields changes, you don't have to update your combined field.

foreach (DataRow row in dt.Rows)
{
    foreach (DataColumn column in dt.Columns)
    {
        ColumnName = column.ColumnName;
        ColumnData = row[column].ToString();
    }
}

It can also happen when drawing a new (other) table. I solved this by first removing the previous table:

$("#prod_tabel_ph").remove();

You might want to use the detach program. You use it like nohup but it doesn't produce an output log unless you tell it to. Here is the man page:

NAME
       detach - run a command after detaching from the terminal

SYNOPSIS
       detach [options] [--] command [args]

       Forks  a  new process, detaches is from the terminal, and executes com-
       mand with the specified arguments.

OPTIONS
       detach recognizes a couple of options, which are discussed below.   The
       special  option -- is used to signal that the rest of the arguments are
       the command and args to be passed to it.

       -e file
              Connect file to the standard error of the command.

       -f     Run in the foreground (do not fork).

       -i file
              Connect file to the standard input of the command.

       -o file
              Connect file to the standard output of the command.

       -p file
              Write the pid of the detached process to file.

EXAMPLE
       detach xterm

       Start an xterm that will not be closed when the current shell exits.

AUTHOR
       detach was written by Robbert Haarman.  See  http://inglorion.net/  for
       contact information.

Note I have no affiliation with the author of the program. I'm only a satisfied user of the program.

If you are using c# 3.0 (or above) you can use extenders

Try using null for the background ...

An inner class, by definition, cannot be static, so I am going to recast your question as "What is the difference between static and non-static nested classes?"

A non-static nested class has full access to the members of the class within which it is nested. A static nested class does not have a reference to a nesting instance, so a static nested class cannot invoke non-static methods or access non-static fields of an instance of the class within which it is nested.

You can not sort TreeMap on values.

A Red-Black tree based NavigableMap implementation. The map is sorted according to the natural ordering of its keys, or by a Comparator provided at map creation time, depending on which constructor is used You will need to provide comparator for Comparator<? super K> so your comparator should compare on keys.

To provide sort on values you will need SortedSet. Use

SortedSet<Map.Entry<String, Double>> sortedset = new TreeSet<Map.Entry<String, Double>>(
            new Comparator<Map.Entry<String, Double>>() {
                @Override
                public int compare(Map.Entry<String, Double> e1,
                        Map.Entry<String, Double> e2) {
                    return e1.getValue().compareTo(e2.getValue());
                }
            });

  sortedset.addAll(myMap.entrySet());

To give you an example

    SortedMap<String, Double> myMap = new TreeMap<String, Double>();
    myMap.put("a", 10.0);
    myMap.put("b", 9.0);
    myMap.put("c", 11.0);
    myMap.put("d", 2.0);
    sortedset.addAll(myMap.entrySet());
    System.out.println(sortedset);

Output:

  [d=2.0, b=9.0, a=10.0, c=11.0]

I would suggest the following code, you can use this <script language="JavaScript" src="http://j.maxmind.com/app/geoip.js"></script> to get the latitude and longitude of a location, although it may not be so accurate however it worked for me;

Eran Hammer-Lahav has done an excellent job in explaining the majority of the differences in his article Introducing OAuth 2.0. To summarize, here are the key differences:

More OAuth Flows to allow better support for non-browser based applications. This is a main criticism against OAuth from client applications that were not browser based. For example, in OAuth 1.0, desktop applications or mobile phone applications had to direct the user to open their browser to the desired service, authenticate with the service, and copy the token from the service back to the application. The main criticism here is against the user experience. With OAuth 2.0, there are now new ways for an application to get authorization for a user.

OAuth 2.0 no longer requires client applications to have cryptography. This hearkens back to the old Twitter Auth API, which didn't require the application to HMAC hash tokens and request strings. With OAuth 2.0, the application can make a request using only the issued token over HTTPS.

OAuth 2.0 signatures are much less complicated. No more special parsing, sorting, or encoding.

OAuth 2.0 Access tokens are "short-lived". Typically, OAuth 1.0 Access tokens could be stored for a year or more (Twitter never let them expire). OAuth 2.0 has the notion of refresh tokens. While I'm not entirely sure what these are, my guess is that your access tokens can be short lived (i.e. session based) while your refresh tokens can be "life time". You'd use a refresh token to acquire a new access token rather than have the user re-authorize your application.

Finally, OAuth 2.0 is meant to have a clean separation of roles between the server responsible for handling OAuth requests and the server handling user authorization. More information about that is detailed in the aforementioned article.

Friend. Use this way, There will be no "Undefined variable message" and it will work fine.

<?php
    if(isset($_POST['SubmitButton'])){
        $price = $_POST["price"];
        $qty = $_POST["qty"];
        $message = $price*$qty;
    }

        ?>

An easy and safe method:

editText.clearFocus();
editText.setFocusable(false);

Tiff images can be displayed directly onto IE and safari only.. no support of tiff images on chrome and firefox. you can encode the image and then display it on browser by decoding the encoded image to some other format. Hope this works for you

If you deal with .xlsm file instead of .xls you can use the old method. I was trying to modify vbaProject.bin in .xlsm several times using DBP->DBx method by it didn't work, also changing value of DBP didn't. So I was very suprised that following worked :
1. Save .xlsm as .xls.
2. Use DBP->DBx method on .xls.
3. Unfortunately some erros may occur when using modified .xls file, I had to save .xls as .xlsx and add modules, then save as .xlsm.

That task should be done by the next layer up in your software stack. SQL is a data repository, not a presentation system

You can do it with

CONVERT(VARCHAR(10), fmdate(), 101)

But you shouldn't

I had the same problem, and found a nice solution here: http://blog.e-shell.org/134

This is caused by a mismatch in your database encodings, surely because the database from where you got the SQL dump was encoded as SQL_ASCII while the new one is encoded as UTF8. .. Recode is a small tool from the GNU project that let you change on-the-fly the encoding of a given file.

So I just recoded the dumpfile before playing it back:

postgres> gunzip -c /var/backups/pgall_b1.zip | recode iso-8859-1..u8 | psql test

In Debian or Ubuntu systems, recode can be installed via package.

This query seems to do the trick:

SELECT 
    sys.objects.name AS table_name, 
    sys.columns.name AS column_name
FROM sys.columns JOIN sys.objects 
    ON sys.columns.object_id=sys.objects.object_id
WHERE 
    sys.columns.is_identity=1
    AND
    sys.objects.type in (N'U')

One-liner alternative to the built-in zfill.

This function takes x and converts it to a string, and adds zeros in the beginning only and only if the length is too short:

def zfill_alternative(x,len=4): return ( (('0'*len)+str(x))[-l:] if len(str(x))<len else str(x) )

To sum it up - build-in: zfill is good enough, but if someone is curious on how to implement this by hand, here is one more example.

Sometimes I think we can overcomplicate the solution just to avoid repeating one line of code. This is the reason I landed on this question in the first place.

After thinking about it for a bit I came to the conclusion that the simplest solution is to repeat the ReadLine before and inside the loop.

using (var stringReader = new StringReader(input))
{
    var line = await stringReader.ReadLineAsync();

    while (line != null)
    {
        // do something
        line = await stringReader.ReadLineAsync();
    }
}

I realize this might be considered to not follow the DRY principle, but I think it's worth considering given the simplicity.

Use the implode() function:

$array = array('lastname', 'email', 'phone');
$comma_separated = implode(",", $array);
echo $comma_separated; // lastname,email,phone

Add below to your app.config.

 <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
      <parameters>
        <parameter value="v11.0" />
      </parameters>
    </defaultConnectionFactory>
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>

How about this solution?

It doesn't use the Thread class, but it IS concurrent, and in a way it does exactly what you request

ExecutorService pool = Executors.newFixedThreadPool(2); // creates a pool of threads for the Future to draw from

Future<Integer> value = pool.submit(new Callable<Integer>() {
    @Override
    public Integer call() {return 2;}
});

Now all you do is say value.get() whenever you need to grab your returned value, the thread is started the very second you give value a value so you don't ever have to say threadName.start() on it.

What a Future is, is a promise to the program, you promise the program that you'll get it the value it needs sometime in the near future

If you call .get() on it before it's done, the thread that's calling it will simply just wait until it's done

As of Xcode 8.3, we can use XCTWaiter http://masilotti.com/xctest-waiting/

func waitForElementToAppear(_ element: XCUIElement) -> Bool {
    let predicate = NSPredicate(format: "exists == true")
    let expectation = expectation(for: predicate, evaluatedWith: element, 
                                  handler: nil)

    let result = XCTWaiter().wait(for: [expectation], timeout: 5)
    return result == .completed
}

Another trick is to write a wait function, credit goes to John Sundell for showing it to me

extension XCTestCase {

  func wait(for duration: TimeInterval) {
    let waitExpectation = expectation(description: "Waiting")

    let when = DispatchTime.now() + duration
    DispatchQueue.main.asyncAfter(deadline: when) {
      waitExpectation.fulfill()
    }

    // We use a buffer here to avoid flakiness with Timer on CI
    waitForExpectations(timeout: duration + 0.5)
  }
}

and use it like

func testOpenLink() {
  let delegate = UIApplication.shared.delegate as! AppDelegate
  let route = RouteMock()
  UIApplication.shared.open(linkUrl, options: [:], completionHandler: nil)

  wait(for: 1)

  XCTAssertNotNil(route.location)
}

You just have to read the laravel installation page:

1. Install Composer if not already installed
2. Open a command line and do:

composer global require "laravel/installer"

Inside your htdocs or www directory, use either:

laravel new appName

(this can lead to an error on windows computers while using latest Laravel (1.3.2)) or:

composer create-project --prefer-dist laravel/laravel appName

(this works also on windows) to create a project called "appName".

To use "php artisan xyz" you have to be inside your project root! as artisan is a file php is going to use... Simple as that ;)

I had this issue myself, and I wanted to both be able to set the width, and have it update on rotate and allow the user to scale and zoom the page (the current answer provides the first but prevents the later as a side-effect).. so I came up with a fix that keeps the view width correct for the orientation, but still allows for zooming, though it is not super straight forward.

First, add the following Javascript to the webpage you are displaying:

 <script type='text/javascript'>
 function setViewPortWidth(width) {
  var metatags = document.getElementsByTagName('meta');
  for(cnt = 0; cnt < metatags.length; cnt++) { 
   var element = metatags[cnt];
   if(element.getAttribute('name') == 'viewport') {

    element.setAttribute('content','width = '+width+'; maximum-scale = 5; user-scalable = yes');
    document.body.style['max-width'] = width+'px';
   }
  }
 }
 </script>

Then in your - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation method, add:

float availableWidth = [EmailVC webViewWidth];
NSString *stringJS;

stringJS = [NSString stringWithFormat:@"document.body.offsetWidth"];
float documentWidth = [[_webView stringByEvaluatingJavaScriptFromString:stringJS] floatValue];

if(documentWidth > availableWidth) return; // Don't perform if the document width is larger then available (allow auto-scale)

// Function setViewPortWidth defined in EmailBodyProtocolHandler prepend
stringJS = [NSString stringWithFormat:@"setViewPortWidth(%f);",availableWidth];
[_webView stringByEvaluatingJavaScriptFromString:stringJS];

Additional Tweaking can be done by modifying more of the viewportal content settings:

http://www.htmlgoodies.com/beyond/webmaster/toolbox/article.php/3889591/Detect-and-Set-the-iPhone--iPads-Viewport-Orientation-Using-JavaScript-CSS-and-Meta-Tags.htm

Also, I understand you can put a JS listener for onresize or something like to trigger the rescaling, but this worked for me as I'm doing it from Cocoa Touch UI frameworks.

Hope this helps someone :)

In my version of mail ( Debian linux 4.0 ) the following options work for controlling the source / reply addresses

• the -a switch, for additional headers to apply, supplying a From: header on the command line that will be appended to the outgoing mail header
• the $REPLYTO environment variable specifies a Reply-To: header

so the following sequence

export [email protected]
mail -aFrom:[email protected] -s 'Testing'

The result, in my mail clients, is a mail from [email protected], which any replies to will default to [email protected]

NB: Mac OS users: you don't have -a , but you do have $REPLYTO

NB(2): CentOS users, many commenters have added that you need to use -r not -a

NB(3): This answer is at least ten years old(1), please bear that in mind when you're coming in from Google.

According to the documentation:

$validator = Validator::make($request->all(), [
    'file' => 'max:500000',
]);

The value is in kilobytes. I.e. max:10240 = max 10 MB.

Facebook uses what's called the Open Graph Protocol to decide what things to display when you share a link. The OGP looks at your page and tries to decide what content to show. We can lend a hand and actually tell Facebook what to take from our page.

The way we do that is with og:meta tags.

The tags look something like this -

  <meta property="og:title" content="Stuffed Cookies" />
  <meta property="og:image" content="http://fbwerks.com:8000/zhen/cookie.jpg" />
  <meta property="og:description" content="The Turducken of Cookies" />
  <meta property="og:url" content="http://fbwerks.com:8000/zhen/cookie.html">

You'll need to place these or similar meta tags in the <head> of your HTML file. Don't forget to substitute the values for your own!

For more information you can read all about how Facebook uses these meta tags in their documentation. Here is one of the tutorials from there - https://developers.facebook.com/docs/opengraph/tutorial/

Facebook gives us a great little tool to help us when dealing with these meta tags - you can use the Debugger to see how Facebook sees your URL, and it'll even tell you if there are problems with it.

One thing to note here is that every time you make a change to the meta tags, you'll need to feed the URL through the Debugger again so that Facebook will clear all the data that is cached on their servers about your URL.

Here's an example on how to achieve this:

    <Grid DockPanel.Dock="Right"
      HorizontalAlignment="Right">

        <StackPanel Orientation="Horizontal"
                HorizontalAlignment="Right"
                VerticalAlignment="Center">

            <Button x:Name="MinimizeButton"
                KeyboardNavigation.IsTabStop="False"
                Click="MinimizeWindow"
                Style="{StaticResource MinimizeButton}" 
                Template="{StaticResource MinimizeButtonControlTemplate}" />

            <Button x:Name="MaximizeButton"
                KeyboardNavigation.IsTabStop="False"
                Click="MaximizeClick"
                Style="{DynamicResource MaximizeButton}" 
                Template="{DynamicResource MaximizeButtonControlTemplate}" />

            <Button x:Name="CloseButton"
                KeyboardNavigation.IsTabStop="False"
                Command="{Binding ApplicationCommands.Close}"
                Style="{DynamicResource CloseButton}" 
                Template="{DynamicResource CloseButtonControlTemplate}"/>

        </StackPanel>
    </Grid>
</DockPanel>

Handle Click Events in the code-behind.

For MouseDown -

App.Current.MainWindow.DragMove();

For Minimize Button -

App.Current.MainWindow.WindowState = WindowState.Minimized;

For DoubleClick and MaximizeClick

if (App.Current.MainWindow.WindowState == WindowState.Maximized)
{
    App.Current.MainWindow.WindowState = WindowState.Normal;
}
else if (App.Current.MainWindow.WindowState == WindowState.Normal)
{
    App.Current.MainWindow.WindowState = WindowState.Maximized;
}

I was looking for a similar solution, but the ones mentioned here would not work. My data had all variations of whitespace (space, newline, tab) chars and commas.

To make the column data tsv safe, I replaced all \t chars in the column data with a space, and executed python code on the commandline to generate a csv file, as shown below:

hive -e 'tab_replaced_hql_query' |  python -c 'exec("import sys;import csv;reader = csv.reader(sys.stdin, dialect=csv.excel_tab);writer = csv.writer(sys.stdout, dialect=csv.excel)\nfor row in reader: writer.writerow(row)")'

This created a perfectly valid csv. Hope this helps those who come looking for this solution.

And if you do this often, you might want to save the generated list r

r=map(lambda x: x/10.0,range(0,10))
for i in r:
    print i

Use %p, for "pointer", and don't use anything else*. You aren't guaranteed by the standard that you are allowed to treat a pointer like any particular type of integer, so you'd actually get undefined behaviour with the integral formats. (For instance, %u expects an unsigned int, but what if void* has a different size or alignment requirement than unsigned int?)

*) [See Jonathan's fine answer!] Alternatively to %p, you can use pointer-specific macros from <inttypes.h>, added in C99.

All object pointers are implicitly convertible to void* in C, but in order to pass the pointer as a variadic argument, you have to cast it explicitly (since arbitrary object pointers are only convertible, but not identical to void pointers):

printf("x lives at %p.\n", (void*)&x);
