Copy in plain notepad (git clone https://github.com/./Spoon-Knife.git) and paste it in cmd. now it will work.

Have you tried plugin called " Youtube Live Stream Auto Embed"

Its seems to be working. Check it once.

Try using some shell magic: %%sh %%sh pip install geocoder let me know if it works, thanks

Maybe you should assign the public key to the authorized_keys, the simple way to do this is using ssh-copy-id -i your-pub-key-file user@dest.

This usually happens when you use two ssh keys to access two different GitHub account.

Follow these steps to fix this it look too long but trust me it won't take more than 5 minutes:

Step-1: Create two ssh key pairs:

ssh-keygen -t rsa -C "[email protected]"

Step-2: It will create two ssh keys here:

~/.ssh/id_rsa_account1
~/.ssh/id_rsa_account2

Step-3: Now we need to add these keys:

ssh-add ~/.ssh/id_rsa_account2
ssh-add ~/.ssh/id_rsa_account1

• You can see the added keys list by using this command: ssh-add -l
• You can remove old cached keys by this command: ssh-add -D

Step-4: Modify the ssh config

cd ~/.ssh/
touch config

subl -a config or code config or nano config

Step-5: Add this to config file:

#Github account1
Host github.com-account1
    HostName github.com
    User account1
    IdentityFile ~/.ssh/id_rsa_account1

#Github account2
Host github.com-account2
    HostName github.com
    User account2
    IdentityFile ~/.ssh/id_rsa_account2

Step-6: Update your .git/config file:

Step-6.1: Navigate to account1's project and update host:

[remote "origin"]
        url = [email protected]:account1/gfs.git

If you are invited by some other user in their git Repository. Then you need to update the host like this:

[remote "origin"]
            url = [email protected]:invitedByUserName/gfs.git

Step-6.2: Navigate to account2's project and update host:

[remote "origin"]
        url = [email protected]:account2/gfs.git

Step-7: Update user name and email for each repository separately if required this is not an amendatory step:

Navigate to account1 project and run these:

git config user.name "account1"
git config user.email "[email protected]" 

Navigate to account2 project and run these:

git config user.name "account2"
git config user.email "[email protected]" 

Just restart Visual Studio and in Test Explorer do "Run All" ... All my tests are discovered then.

It was making me crazy also until I realized that the paragraph where the key must be is [mysqld] not [mysql]

So, for 10.3.22-MariaDB-1ubuntu1, my solution is, in /etc/mysql/conf.d/mysql.cnf

[mysqld]
sql_mode = "ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

https://firebase.google.com/docs/firestore/manage-data/transactions

Use transactions and keep a number in the database somewhere that you can increase by one. This way you can get a nice numeric and simple id.

I tried all solutions above (Native, changing url of VCS repository, updating Git, updating IDEA, invalidating Caches), but nothing helped me. Finally I found solution that works for me.

SOLUTION: I closed Idea and replaced content of file ~\.IntelliJIdea20xx.x\config\options\git.xml with this:

<application>
  <component name="Git.Application.Settings">
    <option name="SSH_EXECUTABLE" value="IDEA_SSH" />
  </component>
</application>

Then I started IDEA, try to checkout SSH GIT repository and it works and existing projects works as well. Interesting fact is that when I switch to NATIVE in Idea Settings, repository not working.

I had the exact same issue, after rightly have configured in Mac OSX host a SharedFolder with Auto-Mount enabled. On the Guest OS, it is also required to install VirtualBox Guest Additions. For the case of Windows, it is:

VBoxWindowsAdditions.exe

Right after this installation, i could perfectly view the shared folder content under This PC and Network ("\VBOXSVR\Installers").

I am trying to do something similar to this. As commented above, I think you would want to build a new image with a custom Dockerfile (using the image you pulled as a base image), ADD your certificate, then RUN update-ca-certificates. This way you will have a consistent state each time you start a container from this new image.

# Dockerfile
FROM some-base-image:0.1
ADD you_certificate.crt:/container/cert/path
RUN update-ca-certificates

Let's say a docker build against that Dockerfile produced IMAGE_ID. On the next docker run -d [any other options] IMAGE_ID, the container started by that command will have your certificate info. Simple and reproducible.

Working solution for Windows:

Control Panel > User Accounts > Credential Manager > Generic Credentials

The solution is to add your variable to /etc/profile. Then everything works as expected! Of course you MUST do it as a root user with sudo nano /etc/profile. If you edit it with any other way the system will complain with a damaged /etc/profile, even if you change the permissions to root.

You can link to any file or directory with the help of a simple PowerShell script.

Writing a file shortcut script

Open Windows PowerShell ISE. In the script pane write:

New-Alias ${shortcutName} ${fullFileLocation}

Then head to the command-line pane. Find your PowerShell user profile address with echo $profile. Save the script in this address.

The script in PowerShell's profile address will run each time you open powershell. The shortcut should work with every new PowerShell window.

Writing a directory shortcut script

It requires another line in our script.

function ${nameOfFunction} {set-location ${directory_location}}
New-Alias ${shortcut} ${nameOfFunction} 

The rest is exactly the same.

Enable PowerShell Scripts

By default PowerShell scripts are blocked. To enable them, open settings -> Update & Security -> For developers. Select Developer Mode (might require restart). .

Scroll down to the PowerShell section, tick the "Change execution policy ..." option, and apply.

Open Terminal and type:

pip config set global.target /Users/Bob/Library/Python/3.8/lib/python/site-packages

except instead of

/Users/Bob/Library/Python/3.8/lib/python/site-packages

you would use whatever directory you want.

1. open command line (run as admin)
   
2. go into Mysql server bin folder
   
3. run command: mysqldump -u root -p mydbscheme > mydbscheme_dump.sql
   
4. give your password here against root.

It will work perfect !!

Above solutions did not work for bitbucket. I figured this does the trick:

RUN ssh-keyscan bitbucket.org >> /root/.ssh/known_hosts \
    && eval `ssh-agent` \
    && ssh-add ~/.ssh/[key] \
    && git clone [email protected]:[team]/[repo].git

If you are using Zsh, then try to add this line in ~/.zshrc file & restart terminal.

export JAVA_HOME=$(/usr/libexec/java_home) 

I've found that there are some files that may affect the $PATH variable in macOS (works for me, 10.11 El Capitan), listed below:

1. As the top voted answer said, vi /etc/paths, which is recommended from my point of view.

2. Also don't forget the /etc/paths.d directory, which contains files may affect the $PATH variable, set the git and mono-command path in my case. You can ls -l /etc/paths.d to list items and rm /etc/paths.d/path_you_dislike to remove items.

3. If you're using a "bash" environment (the default Terminal.app, for example), you should check out ~/.bash_profile or ~/.bashrc. There may be not that file yet, but these two files have effects on the $PATH.

4. If you're using a "zsh" environment (Oh-My-Zsh, for example), you should check out ~./zshrc instead of ~/.bash* thing.

And don't forget to restart all the terminal windows, then echo $PATH. The $PATH string will be PATH_SET_IN_3&4:PATH_SET_IN_1:PATH_SET_IN_2.

Noticed that the first two ways (/etc/paths and /etc/path.d) is in / directory which will affect all the accounts in your computer while the last two ways (~/.bash* or ~/.zsh*) is in ~/ directory (aka, /Users/yourusername/) which will only affect your account settings.

      self.rx.viewDidAppearOnce
            .flatMapLatest { _ in RxKeyboard.instance.isHidden }
            .bind(onNext: { [unowned self] isHidden in
                guard !isHidden else { return }
                self.tableView.beginUpdates()
                self.tableView.contentInsetAdjustmentBehavior = .automatic
                self.tableView.endUpdates()
            })
            .disposed(by: self.disposeBag)

Try this:

View decorView = getWindow().getDecorView();
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
          | View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);

Have only tried this on Mac:

• Create a data directory in the root folder of your app
• cd into your wherever you placed your mongo directory when you installed it

• run this command:

  mongod --dbpath ~/path/to/your/app/data

You should be good to go!

Worked example for a specific case:

Let's say you have my-module that you're sharing via npm.

You install it with npm install my-module

You use it thus:

import * as lol from 'my-module';

const a = lol('abc', 'def');

The module's logic is all in index.js:

module.exports = function(firstString, secondString) {

  // your code

  return result
}

To add typings, create a file index.d.ts:

declare module 'my-module' {
  export default function anyName(arg1: string, arg2: string): MyResponse;
}

interface MyResponse {
  something: number;
  anything: number;
}

I always have to check my cheatsheet :-)

Step 1: right-click on the top of putty window and select 'Change settings'.

Step 2: type the name of the session and save.

That's it!. Enjoy!

How to make a button call PHP?

I don't care if the page reloads or displays the results immediately;

Good!

Note: If you don't want to refresh the page see "Ok... but how do I Use Ajax anyway?" below.

I just want to have a button on my website make a PHP file run.

That can be done with a form with a single button:

<form action="">
  <input type="submit" value="my button"/>
</form>

That's it.

Pretty much. Also note that there are cases where ajax is really the way to go.

That depends on what you want. In general terms you only need ajax when you want to avoid realoading the page. Still you have said that you don't care about that.

Why I cannot call PHP directly from JavaScript?

If I can write the code inside HTML just fine, why can't I just reference the file for it in there or make a simple call for it in Javascript?

Because the PHP code is not in the HTML just fine. That's an illusion created by the way most server side scripting languages works (including PHP, JSP, and ASP). That code only exists on the server, and it is no reachable form the client (the browser) without a remote call of some sort.

You can see evidence of this if you ask your browser to show the source code of the page. There you will not see the PHP code, that is because the PHP code is not send to the client, therefore it cannot be executed from the client. That's why you need to do a remote call to be able to have the client trigger the execution of PHP code.

If you don't use a form (as shown above) you can do that remote call from JavaScript with a little thing called Ajax. You may also want to consider if what you want to do in PHP can be done directly in JavaScript.

How to call another PHP file?

Use a form to do the call. You can have it to direct the user to a particlar file:

<form action="myphpfile.php">
  <input type="submit" value="click on me!">
</form>

The user will end up in the page myphpfile.php. To make it work for the current page, set action to an empty string (which is what I did in the example I gave you early).

I just want to link it to a PHP file that will create the permanent blog post on the server so that when I reload the page, the post is still there.

You want to make an operation on the server, you should make your form have the fields you need (even if type="hidden" and use POST):

<form action="" method="POST">
  <input type="text" value="default value, you can edit it" name="myfield">
  <input type="submit" value = "post">
</form>

What do I need to know about it to call a PHP file that will create a text file on a button press?

see: How to write into a file in PHP.

How do you recieve the data from the POST in the server?

I'm glad you ask... Since you are a newb begginer, I'll give you a little template you can follow:

<?php
    if ($_SERVER['REQUEST_METHOD'] === 'POST')
    {
        //Ok we got a POST, probably from a FORM, read from $_POST.
        var_dump($_PSOT); //Use this to see what info we got!
    }
    else
    {
       //You could assume you got a GET
       var_dump($_GET); //Use this to see what info we got!
    }
 ?>
 <!DOCTYPE html>
 <html lang="en">
   <head>
     <meta char-set="utf-8">
     <title>Page title</title>
   </head>
   <body>
     <form action="" method="POST">
       <input type="text" value="default value, you can edit it" name="myfield">
       <input type="submit" value = "post">
     </form>
   </body>
 </html>

Note: you can remove var_dump, it is just for debugging purposes.

How do I...

I know the next stage, you will be asking how to:

1. how to pass variables form a PHP file to another?
2. how to remember the user / make a login?
3. how to avoid that anoying message the appears when you reload the page?

There is a single answer for that: Sessions.

I'll give a more extensive template for Post-Redirect-Get

<?php
    if ($_SERVER['REQUEST_METHOD'] === 'POST')
    {
        var_dump($_PSOT);
        //Do stuff...
        //Write results to session
        session_start();
        $_SESSION['stuff'] = $something;
        //You can store stuff such as the user ID, so you can remeember him.
        //redirect:
        header('Location: ', true, 303);
        //The redirection will cause the browser to request with GET
        //The results of the operation are in the session variable
        //It has empty location because we are redirecting to the same page
        //Otherwise use `header('Location: anotherpage.php', true, 303);`
        exit();
    }
    else
    {
        //You could assume you got a GET
        var_dump($_GET); //Use this to see what info we got!
        //Get stuff from session
        session_start();
        if (array_key_exists('stuff', $_SESSION))
        {
           $something = $_SESSION['stuff'];
           //we got stuff
           //later use present the results of the operation to the user.
        }
        //clear stuff from session:
        unset($_SESSION['stuff']);
        //set headers
        header('Content-Type: text/html; charset=utf-8');
        //This header is telling the browser what are we sending.
        //And it says we are sending HTML in UTF-8 encoding
    }
 ?>
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta char-set="utf-8">
    <title>Page title</title>
  </head>
  <body>
    <?php if (isset($something)){ echo '<span>'.$something.'</span>'}?>;
    <form action="" method="POST">
      <input type="text" value="default value, you can edit it" name="myfield">
      <input type="submit" value = "post">
    </form>
  </body>
</html>

Please look at php.net for any function call you don't recognize. Also - if you don't have already - get a good tutorial on HTML5.

Also, use UTF-8 because UTF-8!

Notes:

I'm making a simple blog site for myself and I've got the code for the site and the javascript that can take the post I write in a textarea and display it immediately.

If are you using a CMS (Codepress, Joomla, Drupal... etc)? That make put some contraints on how you got to do things.

Also, if you are using a framework, you should look at their documentation or ask at their forum/mailing list/discussion page/contact or try to ask the authors.

Ok... but how do I Use Ajax anyway?

Well... Ajax is made easy by some JavaScript libraries. Since you are a begginer, I'll recomend jQuery.

So, let's send something to the server via Ajax with jQuery, I'll use $.post instead of $.ajax for this example.

<?php
    if ($_SERVER['REQUEST_METHOD'] === 'POST')
    {
        var_dump($_PSOT);
        header('Location: ', true, 303);
        exit();
    }
    else
    {
        var_dump($_GET);
        header('Content-Type: text/html; charset=utf-8');
    }
 ?>
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta char-set="utf-8">
    <title>Page title</title>
    <script>
        function ajaxmagic()
        {
            $.post(                             //call the server
                "test.php",                     //At this url
                {
                    field: "value",
                    name: "John"
                }                               //And send this data to it
            ).done(                             //And when it's done
                function(data)
                {
                    $('#fromAjax').html(data);  //Update here with the response
                }
            );
        }
    </script>
  </head>
  <body>
    <input type="button" value = "use ajax", onclick="ajaxmagic()">
    <span id="fromAjax"></span>
  </body>
</html>

The above code will send a POST request to the page test.php.

Note: You can mix sessions with ajax and stuff if you want.

How do I...

1. How do I connect to the database?
2. How do I prevent SQL injection?
3. Why shouldn't I use Mysql_* functions?

... for these or any other, please make another questions. That's too much for this one.

We are using Response.SetCookie() for update the old one cookies and Response.Cookies.Add() are use to add the new cookies. Here below code CompanyId is update in old cookie[OldCookieName].

HttpCookie cookie = Request.Cookies["OldCookieName"];//Get the existing cookie by cookie name.
cookie.Values["CompanyID"] = Convert.ToString(CompanyId);
Response.SetCookie(cookie); //SetCookie() is used for update the cookie.
Response.Cookies.Add(cookie); //The Cookie.Add() used for Add the cookie.

This is what worked for me perfectly:-

// slide the view from its current position to below itself
public void slideUp(final View view, final View llDomestic){

    ObjectAnimator animation = ObjectAnimator.ofFloat(view, "translationY",0f);
    animation.setDuration(100);
    llDomestic.setVisibility(View.GONE);
    animation.start();

}

// slide the view from below itself to the current position
public void slideDown(View view,View llDomestic){
    llDomestic.setVisibility(View.VISIBLE);
    ObjectAnimator animation = ObjectAnimator.ofFloat(view, "translationY",   0f);
    animation.setDuration(100);
    animation.start();
}

llDomestic : The view which you want to hide. view: The view which you want to move down or up.

The IP addresses have changed again.

github publishes the list of used IP addresses here so you can check the IP address in your message against github's list:

https://help.github.com/articles/about-github-s-ip-addresses/

Or more precisely:

https://api.github.com/meta

It looks like this (as I write this answer!):

verifiable_password_authentication  true
github_services_sha "4159703d573ee6f602e304ed25b5862463a2c73d"

1   "54.166.52.62"
2   "23.20.92.3"

If you are unsure whether your IP address is contained in the above list use an CIDR calculator like http://www.subnet-calculator.com/cidr.php to show the valid IP range.

E. g. for 140.82.112.0/20 the IP range is 140.82.112.0 - 140.82.127.255

In a git bash session, you can add a script to ~/.profile or ~/.bashrc (with ~ being usually set to %USERPROFILE%), in order for said session to launch automatically the ssh-agent. If the file doesn't exist, just create it.

This is what GitHub describes in "Working with SSH key passphrases".

The "Auto-launching ssh-agent on Git for Windows" section of that article has a robust script that checks if the agent is running or not. Below is just a snippet, see the GitHub article for the full solution.

# This is just a snippet. See the article above.
if ! agent_is_running; then
    agent_start
    ssh-add
elif ! agent_has_keys; then
    ssh-add
fi

Other Resources:

"Getting ssh-agent to work with git run from windows command shell" has a similar script, but I'd refer to the GitHub article above primarily, which is more robust and up to date.

Also check you remote url. use git@github... instead of https:// proptocol

see https://stackoverflow.com/a/33928364/551811

I had the same issue. And I tried to reset my keys as everyone said, but it still didn't worked. For was because I renamed the app.

So what I did was to reset my keys and also rename app from console. Check this question for more information: Heroku push app problem

Try setting a Windows System Environment variable called _JAVA_OPTIONS with the heap size you want. Java should be able to find it and act accordingly.

I had this problem today, was in a lot of time crunch, so below idea worked:

• setTimeout with 1 sec -- call a function that shows the div
• setTimeout with 10 sec -- call a function that hides the div

Fade is not there, but that bootstrap feeling will be there.

Hope that helps.

I made a PHP script to make it easier. Create an app. In the Graph API Explorer select your App and get a user token with manage_pages and publish_pages permission. Find your page's ID at the bottom of its About page. Fill in the config vars and run the script.

<?php
$args=[
    'usertoken'=>'',
    'appid'=>'',
    'appsecret'=>'',
    'pageid'=>''
];

echo generate_token($args);

function generate_token($args){
    $r=json_decode(file_get_contents("https://graph.facebook.com/v2.8/oauth/access_token?grant_type=fb_exchange_token&client_id={$args['appid']}&client_secret={$args['appsecret']}&fb_exchange_token={$args['usertoken']}")); // get long-lived token
    $longtoken=$r->access_token;
    $r=json_decode(file_get_contents("https://graph.facebook.com/v2.8/me?access_token={$longtoken}")); // get user id
    $userid=$r->id;
    $r=json_decode(file_get_contents("https://graph.facebook.com/v2.8/{$userid}/accounts?access_token={$longtoken}")); // get permanent token
    foreach($r->data as $d) if($d->id==$args['pageid']) return $d->access_token;
}

From Google documentation:

You can hide the navigation bar on Android 4.0 and higher using the SYSTEM_UI_FLAG_HIDE_NAVIGATION flag. This snippet hides both the navigation bar and the status bar:

View decorView = getWindow().getDecorView();
// Hide both the navigation bar and the status bar.
// SYSTEM_UI_FLAG_FULLSCREEN is only available on Android 4.1 and higher, but as
// a general rule, you should design your app to hide the status bar whenever you
// hide the navigation bar.
int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
              | View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);

It's funny how other answers ignore the fact that you can't write to that file...

There are a few workarounds that come to my mind which could help use an arbitrary C:\redirected\settings.xml and use the mvn command as usual happily ever after.

mvn alias

In a Unix shell (or on Cygwin) you can create

alias mvn='mvn --global-settings "C:\redirected\settings.xml"'

so when you're calling mvn blah blah from anywhere the config is "automatically" picked up.
See How to create alias in cmd? if you want this, but don't have a Unix shell.

mvn wrapper

Configure your environment so that mvn is resolved to a wrapper script when typed in the command line:

• Remove your MVN_HOME/bin or M2_HOME/bin from your PATH so mvn is not resolved any more.
• Add a folder to PATH (or use an existing one)

• In that folder create an mvn.bat file with contents:

  call C:\your\path\to\maven\bin\mvn.bat --global-settings "C:\redirected\settings.xml" %*
  

Note: if you want some projects to behave differently you can just create mvn.bat in the same folder as pom.xml so when you run plain mvn it resolves to the local one.

Use where mvn at any time to check how it is resolved, the first one will be run when you type mvn.

mvn.bat hack

If you have write access to C:\your\path\to\maven\bin\mvn.bat, edit the file and add set MAVEN_CMD_LINE_ARG to the :runm2 part:

@REM Start MAVEN2
:runm2
set MAVEN_CMD_LINE_ARGS=--global-settings "C:\redirected\settings.xml" %MAVEN_CMD_LINE_ARGS%
set CLASSWORLDS_LAUNCHER=...

mvn.sh hack

For completeness, you can change the C:\your\path\to\maven\bin\mvn shell script too by changing the exec "$JAVACMD" command's

${CLASSWORLDS_LAUNCHER} "$@"

part to

${CLASSWORLDS_LAUNCHER} --global-settings "C:\redirected\settings.xml" "$@"

Suggestion/Rant

As a person in IT it's funny that you don't have access to your own home folder, for me this constitutes as incompetence from the company you're working for: this is equivalent of hiring someone to do software development, but not providing even the possibility to use anything other than notepad.exe or Microsoft Word to edit the source files. I'd suggest to contact your help desk or administrator and request write access at least to that particular file so that you can change the path of the local repository.

Disclaimer: None of these are tested for this particular use case, but I successfully used all of them previously for various other software.

i was looking for the same. and found this solution.

Use negative regex assertion:

location ~ ^/(?!(favicon\.ico|resources|robots\.txt)) { 
.... # your stuff 
} 

Source Negated Regular Expressions in location

Explanation of Regex :

If URL does not match any of the following path

example.com/favicon.ico
example.com/resources
example.com/robots.txt

Then it will go inside that location block and will process it.

You can do that by storing cookies on client side.

Per the comments to the original post, merges / joins are well-suited for this problem. In particular, an inner join will return only values that are present in both dataframes, making thesetdiff statement unnecessary.

Using the data from Dinre's example:

In base R:

cleanedA <- merge(data_A, data_B[, "index"], by = 1, sort = FALSE)
cleanedB <- merge(data_B, data_A[, "index"], by = 1, sort = FALSE)

Using the dplyr package:

library(dplyr)
cleanedA <- inner_join(data_A, data_B %>% select(index))
cleanedB <- inner_join(data_B, data_A %>% select(index))

To keep the data as two separate tables, each containing only its own variables, this subsets the unwanted table to only its index variable before joining. Then no new variables are added to the resulting table.

To set JAVA_HOME permanently in Mac, I tried following steps.

1. Download and install Java JDK to your Mac. When you install a Java JDK version which will be installed in the following location by default in MAC.

/Library/Java/JavaVirtualMachines

2. Open the .bash_profile file (Here My Mac version is MacOS High Sierra. You may need to open .zshrc file in some different MacOS versions).

atom ~/.bash_profile

3. Add following to your bash_profile file.

Change the JDK version accordingly

export JAVA_HOME="$(/usr/libexec/java_home -v 1.8)"
export JAVA_HOME='/Library/Java/JavaVirtualMachines/jdk1.8.0_271.jdk/Contents/Home'
export PATH=$JAVA_HOME/bin:$PATH

4. Open the Terminal and execute following.

source ~/.bash_profile

Open a new terminal and check 'echo $JAVA_HOME'

Thanks.

You need to add it to your ~/.profile or ~/.bashrc file. 

export PATH="$PATH:/path/to/dir"

Depending on what you're doing, you also may want to symlink to binaries:

cd /usr/bin
sudo ln -s /path/to/binary binary-name

Note that this will not automatically update your path for the remainder of the session. To do this, you should run:

source ~/.profile 
or
source ~/.bashrc

I know this is an old thread but I think the Blaze library is worth checking out. It's built for these types of situations.

From the docs:

Blaze extends the usability of NumPy and Pandas to distributed and out-of-core computing. Blaze provides an interface similar to that of the NumPy ND-Array or Pandas DataFrame but maps these familiar interfaces onto a variety of other computational engines like Postgres or Spark.

Edit: By the way, it's supported by ContinuumIO and Travis Oliphant, author of NumPy.

Keep the previous path, don't overwrite it:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/your/custom/path/

You can add it to your ~/.bashrc:

echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/your/custom/path/' >> ~/.bashrc

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
   

For more details on #2, check this Ask Ubuntu answer. NOTE: #3 is the Ubuntu recommendation but may have security concerns in the real world.

Forever is a very good NodeJs module to do exactly that.

Install forever by typing in the command line

$ npm install forever -g

Then use the following command to run a node.js script

$ forever start /path/to/script.js

You are good to go. Additionally you can run

$ forever list

to see all the running scripts. You can terminate any specific script by typing

$ forever stop [pid]

where [pid] is the process ID of the script you will obtain from the list command. To stop all scripts, you may type

$ forever stopall

A/code.cpp

#include <B/file.hpp>

A/a/code2.cpp

#include <B/file.hpp>

Compile using:

g++ -I /your/source/root /your/source/root/A/code.cpp
g++ -I /your/source/root /your/source/root/A/a/code2.cpp

Edit:

You can use environment variables to change the path g++ looks for header files. From man page:

Some additional environments variables affect the behavior of the preprocessor.

   CPATH
   C_INCLUDE_PATH
   CPLUS_INCLUDE_PATH
   OBJC_INCLUDE_PATH

Each variable's value is a list of directories separated by a special character, much like PATH, in which to look for header files. The special character, "PATH_SEPARATOR", is target-dependent and determined at GCC build time. For Microsoft Windows-based targets it is a semicolon, and for almost all other targets it is a colon.

CPATH specifies a list of directories to be searched as if specified with -I, but after any paths given with -I options on the command line. This environment variable is used regardless of which language is being preprocessed.

The remaining environment variables apply only when preprocessing the particular language indicated. Each specifies a list of directories to be searched as if specified with -isystem, but after any paths given with -isystem options on the command line.

In all these variables, an empty element instructs the compiler to search its current working directory. Empty elements can appear at the beginning or end of a path. For instance, if the value of CPATH is ":/special/include", that has the same effect as -I. -I/special/include.

There are many ways you can change an environment variable. On bash prompt you can do this:

$ export CPATH=/your/source/root
$ g++ /your/source/root/A/code.cpp
$ g++ /your/source/root/A/a/code2.cpp

You can of course add this in your Makefile etc.

Just replace following line

exec -a "$0" "$HERE/chrome" "$@"

with

exec -a "$0" "$HERE/chrome" "$@" --user-data-dir 

all things will be right.

This way worked for me:

adding the path that you like:

export PYTHONPATH=$PYTHONPATH:/path/you/want/to/add

checking: you can run 'export' cmd and check the output or you can check it using this cmd:

python -c "import sys; print(sys.path)"

Add

export PATH=$PATH:/home/me/play

to your ~/.profile and execute

source ~/.profile 

in order to immediately reflect changes to your current terminal instance.

Both works fine. But according to the Apache docs you should avoid using mod_rewrite for simple redirections, and use Redirect instead. So according to them, you should preferably do:

<VirtualHost *:80>
    ServerName www.example.com
    Redirect / https://www.example.com/
</VirtualHost>

<VirtualHost *:443>
    ServerName www.example.com
    # ... SSL configuration goes here
</VirtualHost>

The first / after Redirect is the url, the second part is where it should be redirected.

You can also use it to redirect URLs to a subdomain: Redirect /one/ http://one.example.com/

I had the same problem. Solution: I edit the file with pspad editor, and give it a unix format (Menu - Format -> UNIX)

I believe you can set this format to your file with many other editors

if you need to increase reserved memory, there are VM parameters -Xms and -Xmx, usage e.g. -Xms512m -Xmx512m . There is also parameter -XX:MaxPermSize=256m which changes memory reserved for permanent generation

If your application runs as windows service, in Control panels -> Administration tools -> Services you can add some run parameters to your service

Try this

mainWB.Sheets.Add(After:=mainWB.Sheets(mainWB.Sheets.Count)).Name = new_sheet_name

Updates to reports

In late May 2018, you may begin to see changes in your app's metrics based on your users' deletion of data. Some metrics are calculated based on data from users who have agreed to share their data with developers in aggregate.

The metrics that we provide in the Play Console are adjusted to more closely reflect data from all of your users. However, Google will not display data that falls under certain minimum thresholds.

Delete an app or game

You can permanently remove draft apps or games from your Play Console. You can also delete:

1. Published apps or games that haven't been installed on any devices
2. Published apps or games that no users are entitled to re-install

In these cases, contact our support team to request that your app's or game's data be permanently deleted.

I had the same issue, but due to the fact that I changed the path on apache to a folder outside var/www, I started running into problems.

I fixed it by creating a symlink in var/www/html > home/dev/project which seemed to do the trick, without having to change any permissions...

1. Open web.config in the directory where the old pages reside

2. Then add code for the old location path and new destination as follows:

   <configuration>
     <location path="services.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/services" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
     <location path="products.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/products" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
   </configuration>
   

You may add as many location paths as necessary.

Something like this should work:

sh -c 'cd /tmp && exec pwd'

I found a solution to this problem that works beautifully on Windows, and wanted to share it.

Solutions that didn't work: I have 16GB of RAM and was still having horrible lag. PyCharm takes less than 1GB of RAM for me, so that wasn't the issue. Turning off inspections didn't help at all, and I didn't have any special plugins that I recall. I also tried playing around with CPU affinities for the process, which briefly worked but not really.

What worked beautifully, almost perfectly:

1. Set PyCharm's CPU priority to Above Normal
2. Set the CPU priority for Python processes to Below Normal

You can do this manually, but I recommend using a program which will preserve the setting across restarts and for multiple instances. I used Process Hacker: Right click on the process -> Priority -> Set the priority. Then right click again -> Process -> and select "Save for pycharm64.exe" and similarly for python "Save for python.exe." Finally in Process Hacker go to Options and select "Start when I log on." This will make it so that ALL Pycharm and python executables acquire these CPU priorities, even after restarting the program and/or Windows, and no matter how many python instances you launch.

Basically, much of the PyCharm's lag may be due to conflict with other programs. Think about it: Yes PyCharm requires a lot of CPU, but the PyCharm developers aren't stupid. They have probably at least ensured it can run without lag on an empty core. But now you open Chrome and 30 tabs, Fiddler, an FTP program, iTunes, Word, Slack, etc, and they all compete with PyCharm at the same CPU priority level. Whenever the sum of all programs > 100% on a core, you see lag. Switching to Above Normal priority gives PyCharm something closer to the empty core that it was probably tested on.

As for Below Normal on python.exe, basically you don't want to slow your computer down with your own development. Most python programs are essentially "batch" programs, and you probably won't notice the extra time it takes to run. I don't recommend this if you are developing a graphical interactive program.

Similar to another answer here, but change the http in the rewrite to to $scheme like so:

server {
        listen 80;
        server_name test.com;
        rewrite     ^ $scheme://www.test.com$request_uri? permanent;
}

And edit your main server block server_name variable as following:

server_name  www.test.com;

I had to do this to redirect www.test.com to test.com.

select top 0 *
into #mytemptable
from myrealtable

On the latest Google Chrome Version 79, you can use the chrome://net-internals and select on DNS from the left panel, then tap the Clear host cache button

Another interesting solution where you want to retain the ViewPager while removing the action bar is to have a style as show

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:windowActionBarOverlay">true</item>
    <item name="android:actionBarStyle">@style/NoActionBarStyle</item>
    <item name="android:windowContentOverlay">@null</item>
</style>
<style name="NoActionBarStyle" parent="android:Widget.Holo.ActionBar">
    <item name="android:backgroundSplit">@null</item>
    <item name="android:displayOptions"></item>
</style>

This is the way most of the Dialer applications in android is showing the ViewPager without the action bar.

HTTP Solution

From the documentation, "the right way is to define a separate server for example.org":

server {
    listen       80;
    server_name  example.com;
    return       301 http://www.example.com$request_uri;
}

server {
    listen       80;
    server_name  www.example.com;
    ...
}

HTTPS Solution

For those who want a solution including https://...

server {
        listen 80;
        server_name www.domain.com;
        # $scheme will get the http protocol
        # and 301 is best practice for tablet, phone, desktop and seo
        return 301 $scheme://domain.com$request_uri;
}

server {
        listen 80;
        server_name domain.com;
        # here goes the rest of your config file
        # example 
        location / {

            rewrite ^/cp/login?$ /cp/login.php last;
            # etc etc...

        }
}

Note: I have not originally included https:// in my solution since we use loadbalancers and our https:// server is a high-traffic SSL payment server: we do not mix https:// and http://.

To check the nginx version, use nginx -v.

Strip www from url with nginx redirect

server {
    server_name  www.domain.com;
    rewrite ^(.*) http://domain.com$1 permanent;
}

server {
    server_name  domain.com;
    #The rest of your configuration goes here#
}

So you need to have TWO server codes.

Add the www to the url with nginx redirect

If what you need is the opposite, to redirect from domain.com to www.domain.com, you can use this:

server {
    server_name  domain.com;
    rewrite ^(.*) http://www.domain.com$1 permanent;
}

server {
    server_name  www.domain.com;
    #The rest of your configuration goes here#
}

As you can imagine, this is just the opposite and works the same way the first example. This way, you don't get SEO marks down, as it is complete perm redirect and move. The no WWW is forced and the directory shown!

Some of my code shown below for a better view:

server {
    server_name  www.google.com;
    rewrite ^(.*) http://google.com$1 permanent;
}
server {
       listen 80;
       server_name google.com;
       index index.php index.html;
       ####
       # now pull the site from one directory #
       root /var/www/www.google.com/web;
       # done #
       location = /favicon.ico {
                log_not_found off;
                access_log off;
       }
}

Ok, so here was my process:

keytool -list -v -keystore permanent.jks - got me the alias.

keytool -export -alias alias_name -file certificate_name -keystore permanent.jks - got me the certificate to import.

Then I could import it with the keytool:

keytool -import -alias alias_name -file certificate_name -keystore keystore location

As @Christian Bongiorno says the alias can't already exist in your keystore.

Many UNIX programs respect the http_proxy environment variable, curl included. The format curl accepts is [protocol://]<host>[:port].

In your shell configuration:

export http_proxy http://proxy.server.com:3128

For proxying HTTPS requests, set https_proxy as well.

Curl also allows you to set this in your .curlrc file (_curlrc on Windows), which you might consider more permanent:

http_proxy=http://proxy.server.com:3128

Well, this question appears on top of search results, so I believe we need code example here. Here's the Python code:

import cv2

def apply_mask(frame, mask):
    """Apply binary mask to frame, return in-place masked image."""
    return cv2.bitwise_and(frame, frame, mask=mask)

Mask and frame must be the same size, so pixels remain as-is where mask is 1 and are set to zero where mask pixel is 0.

And for C++ it's a little bit different:

cv::Mat inFrame; // Original (non-empty) image
cv::Mat mask; // Original (non-empty) mask

// ...

cv::Mat outFrame;  // Result output
inFrame.copyTo(outFrame, mask);

The effect of the 301 would be that the search engines will index /option-a instead of /option-x. Which is probably a good thing since /option-x is not reachable for the search index and thus could have a positive effect on the index. Only if you use this wisely ;-)

After the redirect put exit(); to stop the rest of the script to execute

header("HTTP/1.1 301 Moved Permanently"); 
header("Location: /option-a"); 
exit();

Since you are not worried about IE, why not just use css transitions to provide the animation and jQuery to change the classes. Live example: http://jsfiddle.net/tw16/JfK6N/

#someDiv{
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

try this one:

 KeychainItemWrapper *keychainItem = [[KeychainItemWrapper alloc] initWithIdentifier:@"YourAppLogin" accessGroup:nil];
[keychainItem setObject:@"password you are saving" forKey:kSecValueData]; 
[keychainItem setObject:@"username you are saving" forKey:kSecAttrAccount];

may it will help.

5. Something else - there must be other solutions out there?

You're right, there is! And it is called JWT (JSON Web Tokens).

JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed. JWTs can be signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA.

I highly recommend looking into JWTs. They're a much simpler solution to the problem when compared against alternative solutions.

https://jwt.io/introduction/

You can use the "User-Defined Language" option available at the notepad++. You do not need to do the xml-based hacks, where the formatting would be available only in the searched window, with the formatting rules.

Sample for your reference here.

It's a language abstraction - some languages have both, some one, some neither.

In the case of C++, the code is not run in either the stack or the heap. You can test what happens if you run out of heap memory by repeatingly calling new to allocate memory in a loop without calling delete to free it it. But make a system backup before doing this.

The second top answer mentions ifeq, however, it fails to mention that these must be on the same level as the name of the target, e.g., to download a file only if it doesn't currently exist, the following code could be used:

download:
ifeq (,$(wildcard ./glob.c))
    curl … -o glob.c
endif

# THIS DOES NOT WORK!
download:
    ifeq (,$(wildcard ./glob.c))
        curl … -o glob.c
    endif

I see the status field on the jqXhr object, here is a fiddle with it working:

http://jsfiddle.net/magicaj/55HQq/3/

$.ajax({
    //...        
    success: function(data, textStatus, xhr) {
        console.log(xhr.status);
    },
    complete: function(xhr, textStatus) {
        console.log(xhr.status);
    } 
});

In addition to the above comments, I would like to add few points about Views.

1. Views can be used to hide complexity. Imagine a scenario where 5 people are working on a project but only one of them is too good with database stuff like complex joins. In such scenario, he can create Views which can be easily queried by other team members as they are querying any single table.
2. Security can be easily implemented by Views. Suppose we a Table Employee which contains sensitive columns like Salary, SSN number. These columns are not supposed to be visible to the users who are not authorized to view them. In such case, we can create a View selecting the columns in a table which doesn't require any authorization like Name, Age etc, without exposing sensitive columns (like Salary etc. we mentioned before). Now we can remove permission to directly query the table Employee and just keep the read permission on the View. In this way, we can implement security using Views.

With log4j 1.x I find the best way is to use a DOMConfigurator to submit one of a predefined set of XML log configurations (say, one for normal use and one for debugging).

Making use of these can be done with something like this:

  public static void reconfigurePredefined(String newLoggerConfigName) {
    String name = newLoggerConfigName.toLowerCase();
    if ("default".equals(name)) {
      name = "log4j.xml";
    } else {
      name = "log4j-" + name + ".xml";
    }

    if (Log4jReconfigurator.class.getResource("/" + name) != null) {
      String logConfigPath = Log4jReconfigurator.class.getResource("/" + name).getPath();
      logger.warn("Using log4j configuration: " + logConfigPath);
      try (InputStream defaultIs = Log4jReconfigurator.class.getResourceAsStream("/" + name)) {
        new DOMConfigurator().doConfigure(defaultIs, LogManager.getLoggerRepository());
      } catch (IOException e) {
        logger.error("Failed to reconfigure log4j configuration, could not find file " + logConfigPath + " on the classpath", e);
      } catch (FactoryConfigurationError e) {
        logger.error("Failed to reconfigure log4j configuration, could not load file " + logConfigPath, e);
      }
    } else {
      logger.error("Could not find log4j configuration file " + name + ".xml on classpath");
    }
  }

Just call this with the appropriate config name, and make sure that you put the templates on the classpath.

Yes, use INSERT ... ON DUPLICATE KEY UPDATE id=id (it won't trigger row update even though id is assigned to itself).

If you don't care about errors (conversion errors, foreign key errors) and autoincrement field exhaustion (it's incremented even if the row is not inserted due to duplicate key), then use INSERT IGNORE.

Notepad++ v6.6.3 with plugin "XML Tools" and shortcut Ctrl + Alt + Shift + B works fine.

Stumbled upon this question while checking for correct code for duplicate record.

Pardon my ignorance but I don't understand why everyone is ignoring the code "300" which clearly says "multiple choice" or "Ambiguous"

In my opinion this would be the perfect code for building a non standard or a particular system for your own use. I could be wrong as well!

https://tools.ietf.org/html/rfc7231#section-6.4.1

Run this in host server it's premonition issue

chmod -R 700 ~/.ssh

None of the other answers worked for me. Even after fixing my build path issues, doing a refresh, clean, rebuild, and restart (of both eclipse and the computer), I was still getting the little red exclamation point.

I fixed it by closing the project (right-click, close project) and reopening it (double-click the closed project), which seemed to force eclipse to "notice" that the build path problems had been corrected.

I had the same issue on Ubuntu 16.04: some keys were added permanently, for others I had to execute ssh-add on every session. I found out that the keys which were added permanently had both private and public key located in ~/.ssh and the keys which were forgotten on every session had only private keys in ~/.ssh dir. So solution is simple: you should copy both private and public key to ~/.ssh before executing ssh-add.

P.S.: As far as I understand from Gnome wiki my method works thanks to gnome-keyring tool which is part of the Gnome Desktop Environment. Therefore my method should probably work only if you use Gnome or Gnome-based DE.

For me it worked when I changed the .bash_profile file. Just changing .bashrc file worked only till I restarted the shell.

For python 2.7 it should look like:

export PYTHONPATH="$PYTHONPATH:/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python"

at the end of the .bash_profile file.

If you want to delete for example the last 3 commits, run the following command to remove the changes from the file system (working tree) and commit history (index) on your local branch:

git reset --hard HEAD~3

Then run the following command (on your local machine) to force the remote branch to rewrite its history:

git push --force

Congratulations! All DONE!

Some notes:

You can retrieve the desired commit id by running

git log

Then you can replace HEAD~N with <desired-commit-id> like this:

git reset --hard <desired-commit-id>

If you want to keep changes on file system and just modify index (commit history), use --soft flag like git reset --soft HEAD~3. Then you have chance to check your latest changes and keep or drop all or parts of them. In the latter case runnig git status shows the files changed since <desired-commit-id>. If you use --hard option, git status will tell you that your local branch is exactly the same as the remote one. If you don't use --hard nor --soft, the default mode is used that is --mixed. In this mode, git help reset says:

Resets the index but not the working tree (i.e., the changed files are preserved but not marked for commit) and reports what has not been updated.

There are three packagers, and two compilers:

free packager: PAR
commercial packagers: perl2exe, perlapp
compilers: B::C, B::CC

http://search.cpan.org/dist/B-C/perlcompile.pod

(Note: perlfaq3 is still wrong)

For strawberry you need perl-5.16 and B-C from git master (1.43), as B-C-1.42 does not support 5.16.

You can set the default search_path at the database level:

ALTER DATABASE <database_name> SET search_path TO schema1,schema2;

Or at the user or role level:

ALTER ROLE <role_name> SET search_path TO schema1,schema2;

Or if you have a common default schema in all your databases you could set the system-wide default in the config file with the search_path option.

When a database is created it is created by default from a hidden "template" database named template1, you could alter that database to specify a new default search path for all databases created in the future. You could also create another template database and use CREATE DATABASE <database_name> TEMPLATE <template_name> to create your databases.

For Windows Service, you need to run tomcat9w.exe (or 6w/7w/8w) depending on your version of tomcat. First, make sure tomcat is stopped. Then double click on tomcat9w.exe. Navigate to the Java tab. If you know you have 64 bit Windows with 64 bit Java and 64 bit Tomcat, then feel free to set the memory higher than 512. You'll need to do some task manager monitoring to determine how high to set it. For most apps developed in 2019... I'd recommend an initial memory pool of 1024, and the maximum memory pool of 2048. Of course if your computer has tons of RAM... feel free to go as high as you want. Also, see this answer: How to increase Maximum Memory Pool Size? Apache Tomcat 9

You can edit Rprofile in the base library (in 'C:/Program Files/R.Files/library/base/R' by default) to include code to be run on startup. Append

########        User code        ########
.libPaths('C:/my/dir')

to Rprofile using any text editor (like Notepad) to cause R to add 'C:/my/dir' to the list of libraries it knows about.

(Notepad can't save to Program Files, so save your edited Rprofile somewhere else and then copy it in using Windows Explorer.)

Memory in SunHotSpot JVM is organized into three generations: young generation, old generation and permanent generation.

• Young Generation : the newly created objects are allocated to the young gen.
• Old Generation : If the new object requests for a larger heap space, it gets allocated directly into the old gen. Also objects which have survived a few GC cycles gets promoted to the old gen i.e long lived objects house in old gen.
• Permanent Generation : The permanent generation holds objects that the JVM finds convenient to have the garbage collector manage, such as objects describing classes and methods, as well as the classes and methods themselves.

FYI: The permanent gen is not considered a part of the Java heap.

How does the three generations interact/relate to each other? Objects(except the large ones) are first allocated to the young generation. If an object remain alive after x no. of garbage collection cycles it gets promoted to the old/tenured gen. Hence we can say that the young gen contains the short lived objects while the old gen contains the objects having a long life. The permanent gen does not interact with the other two generations.

The server first tries to authenticate you by public key. That doesn't work (I guess you haven't set one up), so it then falls back to 'keyboard-interactive'. It should then ask you for a password, which presumably you're not getting right. Did you see a password prompt?

The main issue with 301 is browser will cache the redirection even if you disabled the redirection from the server level.

Its always better to use 302 if you are enabling the redirection for a short maintenance window.

Using the "Replace all" functionality, you can delete a line directly by ending your pattern with:

• If your file have linux (LF) line ending : $\n?
• If your file have windows (CRLF) line ending : $(\r\n)?

For instance, in your case :

.*#RedirectMatch Permanent.*$\n?

Just coerce the StatusCode to int.

var statusNumber;
try {
   response = (HttpWebResponse)request.GetResponse();
   // This will have statii from 200 to 30x
   statusNumber = (int)response.StatusCode;
}
catch (WebException we) {
    // Statii 400 to 50x will be here
    statusNumber = (int)we.Response.StatusCode;
}

I believe that the password expiration behavior, by default, is to never expire. However, you could set up a profile for your dev user set and set the PASSWORD_LIFE_TIME. See the orafaq for more details. You can see here for an example of one person's perspective and usage.

what platform are you running?..
if its unix, maybe adding

alias java='java -Xmx1g'  

to .bashrc (or similar) work

edit: Changing XmX to Xmx

Here is a list of sitemap generators (from which obviously you can get the list of URLs from a site): http://code.google.com/p/sitemap-generators/wiki/SitemapGenerators

Web Sitemap Generators

The following are links to tools that generate or maintain files in the XML Sitemaps format, an open standard defined on sitemaps.org and supported by the search engines such as Ask, Google, Microsoft Live Search and Yahoo!. Sitemap files generally contain a collection of URLs on a website along with some meta-data for these URLs. The following tools generally generate "web-type" XML Sitemap and URL-list files (some may also support other formats).

Please Note: Google has not tested or verified the features or security of the third party software listed on this site. Please direct any questions regarding the software to the software's author. We hope you enjoy these tools!

What browser are you testing in?

What DOCType have you set?

How exactly are you declaring your CSS?

Are you sure you haven't missed a ; before/after the overflow-y: scroll?

I've just tested the following in IE7 and Firefox and it works fine

<!-- Scroll bar present but disabled when less content -->_x000D_
<div style="width: 200px; height: 100px; overflow-y: scroll;">_x000D_
  test_x000D_
</div>_x000D_
_x000D_
<!-- Scroll bar present and enabled when more contents -->        _x000D_
<div style="width: 200px; height: 100px; overflow-y: scroll;">_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
  test<br />_x000D_
</div>

This sets the path for the current session and prompts the user to add it permanently:

function Set-Path {
    param([string]$x)
    $Env:Path+= ";" +  $x
    Write-Output $Env:Path
    $write = Read-Host 'Set PATH permanently ? (yes|no)'
    if ($write -eq "yes")
    {
        [Environment]::SetEnvironmentVariable("Path",$env:Path, [System.EnvironmentVariableTarget]::User)
        Write-Output 'PATH updated'
    }
}

You can add this function to your default profile, (Microsoft.PowerShell_profile.ps1), usually located at %USERPROFILE%\Documents\WindowsPowerShell.

I think the better solution is to place these lines in your vimrc file

set backupdir=~/vimtmp//,.
set directory=~/vimtmp//,.

The first line is for backup files, the second line for swap files. The double slash at the end ensures that there is no conflict in case of two files having the same name, see comments (at the time of this edit this option is only honored for swap files, not yet for backup files). The ,. allow vim to use the current directory if the former doesn't exist.

You have to create a directory in your home directory called vimtmp for this to work. Also, check that backups are enabled in your config (add set backup if not).

That way you get the benefit of both worlds, you don't have to see the files, but if something does get futzed you can go get your backup file from vimtmp. Don't forget to clean the directory out every now and then.

freopen("/my/newstdin", "r", stdin);
freopen("/my/newstdout", "w", stdout);
freopen("/my/newstderr", "w", stderr);

... do your stuff

freopen("/dev/stdin", "r", stdin);
...
...

This peaks the needle on my round-peg-square-hole-o-meter, what are you trying to accomplish?

Edit:

Remember that stdin, stdout and stderr are file descriptors 0, 1 and 2 for every newly created process. freopen() should keep the same fd's, just assign new streams to them.

So, a good way to ensure that this is actually doing what you want it to do would be:

printf("Stdout is descriptor %d\n", fileno(stdout));
freopen("/tmp/newstdout", "w", stdout);
printf("Stdout is now /tmp/newstdout and hopefully still fd %d\n",
   fileno(stdout));
freopen("/dev/stdout", "w", stdout);
printf("Now we put it back, hopefully its still fd %d\n",
   fileno(stdout));

I believe this is the expected behavior of freopen(), as you can see, you're still only using three file descriptors (and associated streams).

This would override any shell redirection, as there would be nothing for the shell to redirect. However, its probably going to break pipes. You might want to be sure to set up a handler for SIGPIPE, in case your program finds itself on the blocking end of a pipe (not FIFO, pipe).

So, ./your_program --stdout /tmp/stdout.txt --stderr /tmp/stderr.txt should be easily accomplished with freopen() and keeping the same actual file descriptors. What I don't understand is why you'd need to put them back once changing them? Surely, if someone passed either option, they would want it to persist until the program terminated?

Here is the answer in Swift:

let appDomain = NSBundle.mainBundle().bundleIdentifier!
NSUserDefaults.standardUserDefaults().removePersistentDomainForName(appDomain)

Another idea:

Place all your parameters in a properties file (one parameter = one property in this file), then in your main method, load this file (using Properties.load(*fileInputStream*)). So if you want to modify one argument, you will just need to edit your args.properties file, and launch your application without more steps to do...

Of course, this is only for development purposes, but can be really helpfull if you have to change your arguments often...

Not really related match to the original question, but may be someone will find it useful. PermGen is indeed an area in memory where Java used to keep its classes. So, many of us have came across OOM in PermGen, if there were, for example a lot of classes.

Since Java 8, PermGen area has been replaced by MetaSpace area, which is more efficient and is unlimited by default (or more precisely - limited by amount of native memory, depending on 32 or 64 bit jvm and OS virtual memory availability) . However it is possible to tune it in some ways, by for example specifying a max limit for the area. You can find more useful information in this blog post.

In IntelliJ 14 it has moved again somewhat down the menu.

Now we have it unter Editor -> General -> Appearance

4 years late on the topic, but this might be helpful to someone.

If you forgot to create a new branch before committing and committed all on master, no matter how many commits you did, the following approach is easier:

git stash                       # skip if all changes are committed
git branch my_feature
git reset --hard origin/master
git checkout my_feature
git stash pop                   # skip if all changes were committed

Now you have your master branch equals to origin/master and all new commits are on my_feature. Note that my_feature is a local branch, not a remote one.

The second table cannot include the table name in the ORDER BY clause.

So...

SELECT table1.field1 FROM table1 ORDER BY table1.field1
UNION
SELECT table2.field1 FROM table2 ORDER BY field1

Does not throw an exception

Put it in a TRY/CATCH.

When RAISERROR is run with a severity of 11 or higher in a TRY block, it transfers control to the associated CATCH block

Reference: MSDN.

EDIT: This works for MSSQL 2005+, but I see that you now have clarified that you are working on MSSQL 2000. I'll leave this here for reference.

In MSDN, Assembly.GetExecutingAssembly Method, is remark about method "getexecutingassembly", that for performance reasons, you should call this method only when you do not know at design time what assembly is currently executing.

The recommended way to retrieve an Assembly object that represents the current assembly is to use the Type.Assembly property of a type found in the assembly.

The following example illustrates:

using System;
using System.Reflection;

public class Example
{
    public static void Main()
    {
        Console.WriteLine("The version of the currently executing assembly is: {0}",
                          typeof(Example).Assembly.GetName().Version);
    }
}

/* This example produces output similar to the following:
   The version of the currently executing assembly is: 1.1.0.0

Of course this is very similar to the answer with helper class "public static class CoreAssembly", but, if you know at least one type of executing assembly, it isn't mandatory to create a helper class, and it saves your time.

private void Form1_Load(object sender, EventArgs e)
    {
        PictureBox pb = new PictureBox();
        pb.Location = new Point(0, 0);
        pb.Size = new Size(150, 150);
        pb.Image = Image.FromFile("E:\\Wallpaper (204).jpg");
        pb.Visible = true;
        this.Controls.Add(pb);
    }

I solved this issue by change to use latest buildToolsVersion

android {
    //...
    buildToolsVersion '26.0.2' // change from '23.0.2'
    //...
}

A minor modification to the above recursive generator solution in variadic flavor:

def product_args(*args):
    if args:
        for a in args[0]:
            for prod in product_args(*args[1:]) if args[1:] else ((),):
                yield (a,) + prod

And of course a wrapper which makes it work exactly the same as that solution:

def product2(ar_list):
    """
    >>> list(product(()))
    [()]
    >>> list(product2(()))
    []
    """
    return product_args(*ar_list)

with one trade-off: it checks if recursion should break upon each outer loop, and one gain: no yield upon empty call, e.g.product(()), which I suppose would be semantically more correct (see the doctest).

Regarding list comprehension: the mathematical definition applies to an arbitrary number of arguments, while list comprehension could only deal with a known number of them.

function App() {

  const [todos, setTodos] = useState([
    { id: 1, title: "Selectus aut autem", completed: false },
    { id: 2, title: "Luis ut nam facilis et officia qui", completed: false },
    { id: 3, title: "Fugiat veniam minus", completed: false },
    { id: 4, title: "Aet porro tempora", completed: true },
    { id: 5, title: "Laboriosam mollitia et enim quasi", completed: false }
  ]);

  const changeInput = (e) => {todos.map(items => items.id === parseInt(e.target.value) && (items.completed = e.target.checked));
 setTodos([...todos], todos);}
  return (
    <div className="container">
      {todos.map(items => {
        return (
          <div key={items.id}>
            <label>
<input type="checkbox" 
onChange={changeInput} 
value={items.id} 
checked={items.completed} />&nbsp; {items.title}</label>
          </div>
        )
      })}
    </div>
  );
}

These are utf-8 encoded characters. Use utf8_decode() to convert them to normal ISO-8859-1 characters.

If you want to avoid importing anything and avoid more complex areas of Python, you can use a simple for loop

product = 1  # Don't use 0 here, otherwise, you'll get zero 
             # because anything times zero will be zero.
list = [1, 2, 3]
for x in list:
    product *= x

Try:

<?php

if (isset($_POST['name'])) {
    $name = $_POST['name'];
}

if (isset($_POST['price'])) {
    $price = $_POST['price'];
}

if (isset($_POST['description'])) {
    $description = $_POST['description'];
}

?>

Why not just decorate link tag with the same css as a button.

<Link 
 className="btn btn-pink"
 role="button"
 to="/"
 onClick={this.handleClick()}
> 
 Button1

I write this additional answer to explain the origins of the diffusion of the spikes when using FFT and especially discuss the scipy.fftpack tutorial with which I disagree at some point.

In this example, the recording time tmax=N*T=0.75. The signal is sin(50*2*pi*x) + 0.5*sin(80*2*pi*x). The frequency signal should contain two spikes at frequencies 50 and 80 with amplitudes 1 and 0.5. However, if the analysed signal does not have a integer number of periods diffusion can appear due to the truncation of the signal:

• Pike 1: 50*tmax=37.5 => frequency 50 is not a multiple of 1/tmax => Presence of diffusion due to signal truncation at this frequency.
• Pike 2: 80*tmax=60 => frequency 80 is a multiple of 1/tmax => No diffusion due to signal truncation at this frequency.

Here is a code that analyses the same signal as in the tutorial (sin(50*2*pi*x) + 0.5*sin(80*2*pi*x)), but with the slight differences:

1. The original scipy.fftpack example.
2. The original scipy.fftpack example with an integer number of signal periods (tmax=1.0 instead of 0.75 to avoid truncation diffusion).
3. The original scipy.fftpack example with an integer number of signal periods and where the dates and frequencies are taken from the FFT theory.

The code:

import numpy as np
import matplotlib.pyplot as plt
import scipy.fftpack

# 1. Linspace
N = 600
# Sample spacing
tmax = 3/4
T = tmax / N # =1.0 / 800.0
x1 = np.linspace(0.0, N*T, N)
y1 = np.sin(50.0 * 2.0*np.pi*x1) + 0.5*np.sin(80.0 * 2.0*np.pi*x1)
yf1 = scipy.fftpack.fft(y1)
xf1 = np.linspace(0.0, 1.0/(2.0*T), N//2)

# 2. Integer number of periods
tmax = 1
T = tmax / N # Sample spacing
x2 = np.linspace(0.0, N*T, N)
y2 = np.sin(50.0 * 2.0*np.pi*x2) + 0.5*np.sin(80.0 * 2.0*np.pi*x2)
yf2 = scipy.fftpack.fft(y2)
xf2 = np.linspace(0.0, 1.0/(2.0*T), N//2)

# 3. Correct positioning of dates relatively to FFT theory ('arange' instead of 'linspace')
tmax = 1
T = tmax / N # Sample spacing
x3 = T * np.arange(N)
y3 = np.sin(50.0 * 2.0*np.pi*x3) + 0.5*np.sin(80.0 * 2.0*np.pi*x3)
yf3 = scipy.fftpack.fft(y3)
xf3 = 1/(N*T) * np.arange(N)[:N//2]

fig, ax = plt.subplots()
# Plotting only the left part of the spectrum to not show aliasing
ax.plot(xf1, 2.0/N * np.abs(yf1[:N//2]), label='fftpack tutorial')
ax.plot(xf2, 2.0/N * np.abs(yf2[:N//2]), label='Integer number of periods')
ax.plot(xf3, 2.0/N * np.abs(yf3[:N//2]), label='Correct positioning of dates')
plt.legend()
plt.grid()
plt.show()

Output:

As it can be here, even with using an integer number of periods some diffusion still remains. This behaviour is due to a bad positioning of dates and frequencies in the scipy.fftpack tutorial. Hence, in the theory of discrete Fourier transforms:

• the signal should be evaluated at dates t=0,T,...,(N-1)*T where T is the sampling period and the total duration of the signal is tmax=N*T. Note that we stop at tmax-T.
• the associated frequencies are f=0,df,...,(N-1)*df where df=1/tmax=1/(N*T) is the sampling frequency. All harmonics of the signal should be multiple of the sampling frequency to avoid diffusion.

In the example above, you can see that the use of arange instead of linspace enables to avoid additional diffusion in the frequency spectrum. Moreover, using the linspace version also leads to an offset of the spikes that are located at slightly higher frequencies than what they should be as it can be seen in the first picture where the spikes are a little bit at the right of the frequencies 50 and 80.

I'll just conclude that the example of usage should be replace by the following code (which is less misleading in my opinion):

import numpy as np
from scipy.fftpack import fft

# Number of sample points
N = 600
T = 1.0 / 800.0
x = T*np.arange(N)
y = np.sin(50.0 * 2.0*np.pi*x) + 0.5*np.sin(80.0 * 2.0*np.pi*x)
yf = fft(y)
xf = 1/(N*T)*np.arange(N//2)
import matplotlib.pyplot as plt
plt.plot(xf, 2.0/N * np.abs(yf[0:N//2]))
plt.grid()
plt.show()

Output (the second spike is not diffused anymore):

I think this answer still bring some additional explanations on how to apply correctly discrete Fourier transform. Obviously, my answer is too long and there is always additional things to say (ewerlopes talked briefly about aliasing for instance and a lot can be said about windowing), so I'll stop.

I think that it is very important to understand deeply the principles of discrete Fourier transform when applying it because we all know so much people adding factors here and there when applying it in order to obtain what they want.

Use INDIRECT()

=SUM(INDIRECT(<start cell here> & ":" & <end cell here>))

FFWD to 2019. Although this code worketh in 2011 too.

// g++ prog.cc -Wall -std=c++11
#include <iostream>
#include <vector>

 using namespace std;

 template<size_t N>
    inline 
      constexpr /* compile time */
      array<char,N> string_literal_to_array ( char const (&charrar)[N] )
 {
    return std::to_array( charrar) ;
 }

 template<size_t N>
    inline 
      /* run time */
      vector<char> string_literal_to_vector ( char const (&charrar)[N] )
 {
    return { charrar, charrar + N };
 }


int main()
{
   constexpr auto arr = string_literal_to_array("Compile Time");
   auto cv = string_literal_to_vector ("Run Time") ;
   return 42;
}

Advice: try optimizing the use of std::string. For char buffering std::array<char,N> is the fastest, std::vector<char> is faster.

Years ago I wrote a colored stream handler for my own use. Then I came across this page and found a collection of code snippets that people are copy/pasting :-(. My stream handler currently only works on UNIX (Linux, Mac OS X) but the advantage is that it's available on PyPI (and GitHub) and it's dead simple to use. It also has a Vim syntax mode :-). In the future I might extend it to work on Windows.

To install the package:

$ pip install coloredlogs

To confirm that it works:

$ coloredlogs --demo

To get started with your own code:

$ python
> import coloredlogs, logging
> coloredlogs.install()
> logging.info("It works!")
2014-07-30 21:21:26 peter-macbook root[7471] INFO It works!

The default log format shown in the above example contains the date, time, hostname, the name of the logger, the PID, the log level and the log message. This is what it looks like in practice:

NOTE: When using Git Bash w/ MinTTY

Git Bash on windows has some documented quirks: Winpty and Git Bash

Which for ANSI escape codes and for ncurses style character rewriting and animations, you need to prefix commands with winpty.

$ winpty coloredlogs --demo
$ winpty python your_colored_logs_script.py

Worked here too:

Sub test544()

  Dim chromePath As String

  chromePath = """C:\Program Files\Google\Chrome\Application\chrome.exe"""

  Shell (chromePath & " -url http:google.ca")

End Sub

This is even more frustrating because now (.net 5) MS have marked many (all) of their methods that take a string instead of a Uri as obsolete.

Anyway, probably a better way to manipulate relative Uris is to give it what it wants:

var requestUri = new Uri("x://x").MakeRelativeUri(
   new UriBuilder("x://x") { Path = path, Query = query }.Uri);

You can use the other answers to actually build the query string.

First off, your code is a bit off. aes() is an argument in ggplot(), you don't use ggplot(...) + aes(...) + layers

Second, from the help file ?geom_bar:

By default, geom_bar uses stat="count" which makes the height of the bar proportion to the number of cases in each group (or if the weight aethetic is supplied, the sum of the weights). If you want the heights of the bars to represent values in the data, use stat="identity" and map a variable to the y aesthetic.

You want the second case, where the height of the bar is equal to the conversion_rate So what you want is...

data_country <- data.frame(country = c("China", "Germany", "UK", "US"), 
            conversion_rate = c(0.001331558,0.062428188, 0.052612025, 0.037800687))
ggplot(data_country, aes(x=country,y = conversion_rate)) +geom_bar(stat = "identity")

Result:

The approach for getting a collection of distinct value from a group of keys.

You could take the given code from here and add a mapping for only the wanted keys to get an array of unique object values.

const_x000D_
    listOfTags = [{ id: 1, label: "Hello", color: "red", sorting: 0 }, { id: 2, label: "World", color: "green", sorting: 1 }, { id: 3, label: "Hello", color: "blue", sorting: 4 }, { id: 4, label: "Sunshine", color: "yellow", sorting: 5 }, { id: 5, label: "Hello", color: "red", sorting: 6 }],_x000D_
    keys = ['label', 'color'],_x000D_
    filtered = listOfTags.filter(_x000D_
        (s => o =>_x000D_
            (k => !s.has(k) && s.add(k))_x000D_
            (keys.map(k => o[k]).join('|'))_x000D_
        )(new Set)_x000D_
    )_x000D_
    result = filtered.map(o => Object.fromEntries(keys.map(k => [k, o[k]])));_x000D_
_x000D_
console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

Wrap them in another class so that you can end up with a single array or List of those objects.

public class Data {
    private String txtFileName;
    private String imgFileName;

    // Add/generate c'tor, getter/setter, equals, hashCode and other boilerplate.
}

Usage example:

List<Data> list = new ArrayList<Data>();
list.add(new Data("H1.txt", "e1.jpg"));
list.add(new Data("H2.txt", "e2.jpg"));
// ...

Collections.shuffle(list);

DataSet ds = new DataSet();

using (OleDbConnection connection = new OleDbConnection(connectionString))
using (OleDbCommand command = new OleDbCommand(query, connection))
using (OleDbDataAdapter adapter = new OleDbDataAdapter(command))
{
    adapter.Fill(ds);
}

return ds;

In a POST method, you can put an array. However, in a PUT method, you should use http_build_query to build the params like this:

curl_setopt( $ch, CURLOPT_POSTFIELDS, http_build_query( $postArr ) );

enabledBorder: OutlineInputBorder(
  borderRadius: BorderRadius.circular(10.0),
  borderSide: BorderSide(color: Colors.red)
),

Try this :

SELECT
    (
      SELECT
          `NAME`
      FROM
          locations
      WHERE
          ID = school_locations.LOCATION_ID
    ) as `NAME`
FROM
     school_locations
WHERE
     (
      SELECT
          `TYPE`
      FROM
          locations
      WHERE
          ID = school_locations.LOCATION_ID
     ) = 'coun';

I also got the same error but I noticed that I had typed in Foreign*k*ey and not Foreign*K*ey,(capital K) if there is a newbie out there, check out spelling and caps.

I loved @Slai's answer. I only had to make very minor modifications into the one-liners I was looking for. I thought I'd share what I ended up with in case it helps anyone else stumbling onto this page like I did:

DECLARE @Source VARCHAR(50) = '12345'
DECLARE @Encoded VARCHAR(500) = CONVERT(VARCHAR(500), (SELECT CONVERT(VARBINARY, @Source) FOR XML PATH(''), BINARY BASE64))
DECLARE @Decoded VARCHAR(500) = CONVERT(VARCHAR(500), CONVERT(XML, @Encoded).value('.','varbinary(max)'))
SELECT @Source AS [Source], @Encoded AS [Encoded], @Decoded AS [Decoded]

There are many ways you can take back of table.

1. BCP (BULK COPY PROGRAM)
2. Generate Table Script with data
3. Make a copy of table using SELECT INTO, example here
4. SAVE Table Data Directly in a Flat file
5. Export Data using SSIS to any destination

You can try changing it to this:

If myTableData.Rows.Count > 0 Then
  For i As Integer = 0 To myTableData.Rows.Count - 1
    ''Dim DataType() As String = myTableData.Rows(i).Item(1)
    ListBox2.Items.Add(myTableData.Rows(i)(1))
  Next
End If

Note: Your loop needs to be one less than the row count since it's a zero-based index.

Since the syntaxes are equivalent (in MySQL anyhow), I prefer the INSERT INTO table SET x=1, y=2 syntax, since it is easier to modify and easier to catch errors in the statement, especially when inserting lots of columns. If you have to insert 10 or 15 or more columns, it's really easy to mix something up using the (x, y) VALUES (1,2) syntax, in my opinion.

If portability between different SQL standards is an issue, then maybe INSERT INTO table (x, y) VALUES (1,2) would be preferred.

And if you want to insert multiple records in a single query, it doesn't seem like the INSERT INTO ... SET syntax will work, whereas the other one will. But in most practical cases, you're looping through a set of records to do inserts anyhow, though there could be some cases where maybe constructing one large query to insert a bunch of rows into a table in one query, vs. a query for each row, might have a performance improvement. Really don't know.

In most project types, your async "up" and "down" will end at an async void event handler or returning a Task to your framework.

However, Console apps do not support this.

You can either just do a Wait on the returned task:

static void Main()
{
  MainAsync().Wait();
  // or, if you want to avoid exceptions being wrapped into AggregateException:
  //  MainAsync().GetAwaiter().GetResult();
}

static async Task MainAsync()
{
  ...
}

or you can use your own context like the one I wrote:

static void Main()
{
  AsyncContext.Run(() => MainAsync());
}

static async Task MainAsync()
{
  ...
}

More information for async Console apps is on my blog.

you can save the path of the image in the database or save the image itself as a BLOB ( binary - array of bytes)..it depends on the case you got,if your application is a web application,then saving the path of the image is much better.but if you got a client based application that connects to a centralized database,then you must save it as binary.

I personally use a CLR implementation of the Jaro-Winkler algorithm which seems to work pretty well - it struggles a bit with strings longer than about 15 characters and doesn't like matching email addresses but otherwise is quite good - full implementation guide can be found here

If you are unable to use CLR functions for whatever reasons, maybe you could try running the data through an SSIS package (using the fuzzy transformation lookup) - detailed here

You can pass it as a normal prop: foo={<ComponentOne />}

For example:

const ComponentOne = () => <div>Hello world!</div>
const ComponentTwo = () => (
  <div>
    <div>Hola el mundo!</div>
    <ComponentThree foo={<ComponentOne />} />
  </div>
)
const ComponentThree = ({ foo }) => <div>{foo}</div>

Are you meaning?

data2 <- data1[good,]

With

data1[good]

you're selecting columns in a wrong way (using a logical vector of complete rows).

Consider that parameter pollutant is not used; is it a column name that you want to extract? if so it should be something like

data2 <- data1[good, pollutant]

Furthermore consider that you have to rbind the data.frames inside the for loop, otherwise you get only the last data.frame (its completed.cases)

And last but not least, i'd prefer generating filenames eg with

id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")

A little modified chunk of ?sprintf

The string fmt (in our case "%3d") contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through .... The allowed conversion specifications start with a % and end with one of the letters in the set aAdifeEgGosxX%. These letters denote the following types:

• d: integer

Eg a more general example

    sprintf("I am %10d years old", 25)
[1] "I am         25 years old"
          ^^^^^^^^^^
          |        |
          1       10

DateTime dt1=DateTime.ParseExact(date1,"dd-MM-yyyy",null);
DateTime dt2=DateTime.ParseExact(date2,"dd-MM-yyyy",null);

int cmp=dt1.CompareTo(dt2);

   if(cmp>0) {
       // date1 is greater means date1 is comes after date2
   } else if(cmp<0) {
       // date2 is greater means date1 is comes after date1
   } else {
       // date1 is same as date2
   }

For those using the serialize() function:

(function ($) {
    var serialize = $.fn.serialize;

    $.fn.serialize = function () {
        let values = serialize.call(this);
        let checkboxes = [];

        checkboxes = checkboxes.concat(
            $('input[type=checkbox]:not(:checked)', this).map(
            function () {
                return this.name + '=false';
            }).get()
        );

        if(checkboxes.length > 0)
            values = checkboxes.join('&') + '&' + values;

        return values;
    };
})(jQuery);

To get this working in Javascript, I had to do the following:

myString.split(/\s+/g)

Neither of the posted answers worked for me. Setting position: absolute for the child element did work however.

We can use following code

textBox1.DataBindings.Add("Text", model, "Name", false, DataSourceUpdateMode.OnPropertyChanged);

Where

• "Text" – the property of textbox
• model – the model object enter code here
• "Name" – the value of model which to bind the textbox.

There are two ways to tackle this based on what you want:

Solution 1: Remove purple commits, preserving history (incase you want to roll back)

git revert -m 1 <SHA of merge>

-m 1 specifies which parent line to choose

Purple commits will still be there in history but since you have reverted, you will not see code from those commits.

Solution 2: Completely remove purple commits (disruptive change if repo is shared)

git rebase -i <SHA before branching out>

and delete (remove lines) corresponding to purple commits.

This would be less tricky if commits were not made after merge. Additional commits increase the chance of conflicts during revert/rebase.

To set class on the active navigation element

import { NavLink } from 'react-router-dom';

&

<NavLink to="/Home" activeClassName="active">Home</NavLink>

You have a couple of things fighting in your strings.

• lack of correct MySQL quoting (mysql_real_escape_string())
• potential automatic 'magic quote' -- check your gpc_magic_quotes setting
• embedded string variables, which means you have to know how PHP correctly finds variables

It's also possible that the single-quoted value is not present in the parameters to the first query. Your example is a proper name, after all, and only the second query seems to be dealing with names.

In addition to using pure threads or the Celery queue (note that flask-celery is no longer required), you could also have a look at flask-apscheduler:

https://github.com/viniciuschiele/flask-apscheduler

from flask import Flask
from flask_apscheduler import APScheduler

    JOBS = [
        {
            'id': 'job1',
            'func': 'jobs:job1',
            'args': (1, 2),
            'trigger': 'interval',
            'seconds': 10
        }
    ]

    SCHEDULER_API_ENABLED = True


def job1(a, b):
    print(str(a) + ' ' + str(b))

if __name__ == '__main__':

None of these answers fit my specific situation, which was that I wanted to run one specific cron job, just once, and run it immediately.

I'm on a Ubuntu server, and I use cPanel to setup my cron jobs.

I simply wrote down my current settings, and then edited them to be one minute from now. When I fixed another bug, I just edited it again to one minute from now. And when I was all done, I just reset the settings back to how they were before.

Example: It's 4:34pm right now, so I put 35 16 * * *, for it to run at 16:35.

It worked like a charm, and the most I ever had to wait was a little less than one minute.

I thought this was a better option than some of the other answers because I didn't want to run all of my weekly crons, and I didn't want the job to run every minute. It takes me a few minutes to fix whatever the issues were before I'm ready to test it again. Hopefully this helps someone.

"N/A" is not a string it is an error, try this:

=if(ISNA(A1),C1)

you have to place this fomula in cell B1 so it will get the value of your formula

The meta cache control tag allows Web publishers to define how pages should be handled by caches. They include directives to declare what should be cacheable, what may be stored by caches, modifications of the expiration mechanism, and revalidation and reload controls.

The allowed values are:

Public - may be cached in public shared caches
Private - may only be cached in private cache
no-Cache - may not be cached
no-Store - may be cached but not archived

Please be careful about case sensitivity. Add the following meta tag in the source of your webpage. The difference in spelling at the end of the tag is either you use " /> = xml or "> = html.

    <meta http-equiv="Cache-control" content="public">
    <meta http-equiv="Cache-control" content="private">
    <meta http-equiv="Cache-control" content="no-cache">
    <meta http-equiv="Cache-control" content="no-store">

Why don't you try the fadeIn() instead of using a show() with delay(). I think what you are trying to do can be done with this. Here is the jQuery code for fadeIn and FadeOut() which also has inbuilt method for delaying the process.

$(document).ready(function(){
   $('element').click(function(){
      //effects take place in 3000ms
      $('element_to_hide').fadeOut(3000);
      $('element_to_show').fadeIn(3000);
   });
}

for inserting data into table you can write

insert into tablename values(column_name1,column_name2,column_name3);

but write the column_name in the sequence as per sequence in table ...

setState(updater, callback) for useState

Following implementation comes really close to the original setState callback from classes.

Additions made to Robin's solution:

1. Callback execution is omitted on initial render (we want to call it only on state updates)
2. Callback can be dynamic for each setState invocation, like with classes

Usage

const App = () => {
  const [state, setState] = useStateCallback(0); // same API as useState + setState with cb

  const handleClick = () => {
    setState(
      prev => prev + 1,
      // 2nd argument is callback , `s` is *updated* state
      s => console.log("I am called after setState, state:", s)
    );
  };

  return <button onClick={handleClick}>Increment</button>;
}

useStateCallback

function useStateCallback(initialState) {
  const [state, setState] = useState(initialState);
  const cbRef = useRef(null); // mutable ref to store current callback

  const setStateCallback = useCallback((state, cb) => {
    cbRef.current = cb; // store passed callback to ref
    setState(state);
  }, []);

  useEffect(() => {
    // cb.current is `null` on initial render, so we only execute cb on state *updates*
    if (cbRef.current) {
      cbRef.current(state);
      cbRef.current = null; // reset callback after execution
    }
  }, [state]);

  return [state, setStateCallback];
}

Further info: React Hooks FAQ: Is there something like instance variables?

Working example

const App = () => {
  const [state, setState] = useStateCallback(0);

  const handleClick = () =>
    setState(
      prev => prev + 1,
      // important: use `s`, not the stale/old closure value `state`
      s => console.log("I am called after setState, state:", s)
    );

  return (
    <div>
      <p>Hello Comp. State: {state} </p>
      <button onClick={handleClick}>Click me</button>
    </div>
  );
}

function useStateCallback(initialState) {
  const [state, setState] = useState(initialState);
  const cbRef = useRef(null);

  const setStateCallback = useCallback((state, cb) => {
    cbRef.current = cb; 
    setState(state);
  }, []);

  useEffect(() => {
    if (cbRef.current) {
      cbRef.current(state);
      cbRef.current = null;
    }
  }, [state]);

  return [state, setStateCallback];
}

Don't provide the handler to execute.

Get the HttpResponse object, use the handler to get the body and get the status code from it directly

try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
    final HttpGet httpGet = new HttpGet(GET_URL);

    try (CloseableHttpResponse response = httpClient.execute(httpGet)) {
        StatusLine statusLine = response.getStatusLine();
        System.out.println(statusLine.getStatusCode() + " " + statusLine.getReasonPhrase());
        String responseBody = EntityUtils.toString(response.getEntity(), StandardCharsets.UTF_8);
        System.out.println("Response body: " + responseBody);
    }
}

For quick single calls, the fluent API is useful:

Response response = Request.Get(uri)
        .connectTimeout(MILLIS_ONE_SECOND)
        .socketTimeout(MILLIS_ONE_SECOND)
        .execute();
HttpResponse httpResponse = response.returnResponse();
StatusLine statusLine = httpResponse.getStatusLine();

For older versions of java or httpcomponents, the code might look different.

SAP is just a company name and Abap or Abap/4 is a language programming. SAP company has a lot of products: ERP(material, sales, costs, financial), CRM, SRM, SCM and all of them are customizing and programmed with ABAP and Java. Basically is it.

As already hinted at, isin requires columns and indices to be the same for a match. If match should only be on row contents, one way to get the mask for filtering the rows present is to convert the rows to a (Multi)Index:

In [77]: df1 = pandas.DataFrame(data = {'col1' : [1, 2, 3, 4, 5, 3], 'col2' : [10, 11, 12, 13, 14, 10]})
In [78]: df2 = pandas.DataFrame(data = {'col1' : [1, 3, 4], 'col2' : [10, 12, 13]})
In [79]: df1.loc[~df1.set_index(list(df1.columns)).index.isin(df2.set_index(list(df2.columns)).index)]
Out[79]:
   col1  col2
1     2    11
4     5    14
5     3    10

If index should be taken into account, set_index has keyword argument append to append columns to existing index. If columns do not line up, list(df.columns) can be replaced with column specifications to align the data.

pandas.MultiIndex.from_tuples(df<N>.to_records(index = False).tolist())

could alternatively be used to create the indices, though I doubt this is more efficient.

I've been programming for 8 years professionally, and since I was 12 as a hobby.

Math is not necessary, logic is. Math is horribly helpful though, to say it's not necessary is like saying that to kill a man, a gun isn't necessary, you can use a knife. Well, it is true, but that gun makes it a lot easier.

There are a couple bare minimums, which you should already meet. You need to know basic algebraic expressions and notation, and the common computer equivalents. For example, you need to know what an exponential is (3 to the 3rd is 27), and the common computer expression is 3^3. The common notations for algebra does change between languages, but many of them use a somewhat unified methodology. Others (looking at you LISP) don't. You also need to know order of operations.

You need to understand algorithmic thought. First this, then this, produces this which is used in this calculation. Chances are you understand this or you don't, and it's a fairly hard hurdle to jump if you don't understand it; I've found that this is something you 'get', and not really something you can learn. Conversely, some people don't 'get' art. They should not become painters. Also, there have been students in CS curriculum who cannot figure out why this does not work: x = z + w; z = 3; y = 5; It's not that they don't understand addition, it's that they aren't grasping the requirement of unambiguous express. If they understand it, the computer should too, right? If you can't see what's wrong with the above three lines, then don't become a programmer.

Lastly, you need to know whatever math is under your domain of programming. Accounting software could stop at basic algebra. If you are programming physics, you'll need to know physics (loosely) and math in 3-dimensional geometry (Euclidean). If you're programming architecture software, you'll need to know trigonometry.

This goes farther then math though; whatever domain you are programming for, you need to soundly understand the basics. If you are programming language analysis software, you'll need to know probability, statistics, grammar theory (multiple languages), etc.

Often times, certain domains need, or can benefit from, knowledge you'd think is unrelated. For example, if you were programming audio software, you actually need to know trigonometry to deal with waveforms.

Magnitude changes things also. If you are sorting a financial data set of 1000 items, it's no big thing. If it was 10 million records, however, you would benefit greatly from knowing vector math actually, and having a deep understanding of sorting at the binary level (how does a system sort alphabetically? How does it know 'a' is less than 'b'?)

You are going to find that as a programmer, your general knowledge base is going to explode, because each project will necessitate more learning outside of the direct sphere of programming. If you are squeamish or lazy about self-learning, and do not like the idea of spending 10+ hours a week doing essentially 'homework', do not become a programmer.

If you like thought exercises, if you like learning, if you can think about abstract things like math without a calculator or design without a sketchpad, if you have broad tastes in life and hobbies, if you are self-critical and can throw away 'favorited' ideas, if you like perfecting things, then become a programmer. Do not base this decision on math, but rather, the ability to think logically and learn. Those are what is important; math is just the by-product.

Switch value must have an Integral type. Also, since you know that differenciating character is in position 7, you could switch on a.at(7). But you are not sure the user entered 8 characters. He may as well have done some typing mistake. So you are to surround your switch statement within a Try Catch. Something with this flavour

#include<iostream>
using namespace std;
int main() {
    string a;
    cin>>a;

    try
    {
    switch (a.at(7)) {
    case '1':
        cout<<"It pressed number 1"<<endl;
        break;
    case '2':
        cout<<"It pressed number 2"<<endl;
        break;
    case '3':
        cout<<"It pressed number 3"<<endl;
        break;
    default:
        cout<<"She put no choice"<<endl;
        break;
    }
    catch(...)
    {

    }
    }
    return 0;
}

The default clause in switch statement captures cases when users input is at least 8 characters, but not in {1,2,3}.

Alternatively, you can switch on values in an enum.

EDIT

Fetching 7th character with operator[]() does not perform bounds check, so that behavior would be undefined. we use at() from std::string, which is bounds-checked, as explained here.

This is similar to Alex's but does it in log time instead of linear, and takes a maxHeight parameter.

jQuery.fn.ellipsis = function(text, maxHeight) {
  var element = $(this);
  var characters = text.length;
  var step = text.length / 2;
  var newText = text;
  while (step > 0) {
    element.html(newText);
    if (element.outerHeight() <= maxHeight) {
      if (text.length == newText.length) {
        step = 0;
      } else {
        characters += step;
        newText = text.substring(0, characters);
      }
    } else {
      characters -= step;
      newText = newText.substring(0, characters);
    }
    step = parseInt(step / 2);
  }
  if (text.length > newText.length) {
    element.html(newText + "...");
    while (element.outerHeight() > maxHeight && newText.length >= 1) {
      newText = newText.substring(0, newText.length - 1);
      element.html(newText + "...");
    }
  }
};

Here's the function that I used:

public boolean exists(String table) {
    try {
         db.query("SELECT * FROM " + table);

         return false;
    }
}

Here is a useful article by Michael J. Swart on the matter, which covers different patterns and antipatterns for implementing UPSERT in SQL Server:
https://michaeljswart.com/2017/07/sql-server-upsert-patterns-and-antipatterns/

It addresses associated concurrency issues (primary key violations, deadlocks) - all of the answers provided here yet are considered antipatterns in the article (except for the @Bridge solution using triggers, which is not covered there).

Here is an extract from the article with the solution preferred by the author:

Inside a serializable transaction with lock hints:

CREATE PROCEDURE s_AccountDetails_Upsert ( @Email nvarchar(4000), @Etc nvarchar(max) )
AS 
  SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
  BEGIN TRAN

    IF EXISTS ( SELECT * FROM dbo.AccountDetails WITH (UPDLOCK) WHERE Email = @Email )

      UPDATE dbo.AccountDetails
         SET Etc = @Etc
       WHERE Email = @Email;

    ELSE 

      INSERT dbo.AccountDetails ( Email, Etc )
      VALUES ( @Email, @Etc );

  COMMIT

A possible solution might be to use the JSON dumps() method, so you can convert the dictionary to a string ---

import json

a={"a":10, "b":20}
b={"b":20, "a":10}
c = [json.dumps(a), json.dumps(b)]


set(c)
json.dumps(a) in c

Output -

set(['{"a": 10, "b": 20}'])
True

If week 1 always starts on the first Monday of the month try this formula for week number

=INT((6+DAY(A1+1-WEEKDAY(A1-1)))/7)

That gets the week number from the date in A1 with no intermediate calculations - if you want to use your "Monday's date" in B1 you can use this version

=INT((DAY(B1)+6)/7)

You want conda update --all.

conda search --outdated will show outdated packages, and conda update --all will update them (note that the latter will not update you from Python 2 to Python 3, but the former will show Python as being outdated if you do use Python 2).

Yes, use INSERT ... ON DUPLICATE KEY UPDATE id=id (it won't trigger row update even though id is assigned to itself).

If you don't care about errors (conversion errors, foreign key errors) and autoincrement field exhaustion (it's incremented even if the row is not inserted due to duplicate key), then use INSERT IGNORE.

Yes, I understood your problem. If is difficult to identify cell has Numeric or Data value.

If you want data in format that shows in Excel, you just need to format cell using DataFormatter class.

DataFormatter dataFormatter = new DataFormatter();
String cellStringValue = dataFormatter.formatCellValue(row.getCell(0));
System.out.println ("Is shows data as show in Excel file" + cellStringValue);  // Here it automcatically format data based on that cell format.
// No need for extra efforts 

For those who rooted the Android device with Magisk, you can install adb_root from https://github.com/evdenis/adb_root. Then adb root can run smoothly.

Have a look this:

use yii\helpers\ArrayHelper; // load classes
use app\models\Course;
    .....
$dataList=ArrayHelper::map(Course::find()->asArray()->all(), 'id', 'name');
<?=$form->field($model, 'center_id')->dropDownList($dataList, 
         ['prompt'=>'-Choose a Course-']) ?>

For me, the revelation came when I realized that they all work the same way: by running something once, storing the value they get, and then cough up that same stored value when referenced through dependency injection.

Say we have:

app.factory('a', fn);
app.service('b', fn);
app.provider('c', fn);

The difference between the three is that:

1. a's stored value comes from running fn.
2. b’s stored value comes from newing fn.
3. c’s stored value comes from first getting an instance by newing fn, and then running a $get method of the instance.

Which means there’s something like a cache object inside AngularJS, whose value of each injection is only assigned once, when they've been injected the first time, and where:

cache.a = fn()
cache.b = new fn()
cache.c = (new fn()).$get()

This is why we use this in services, and define a this.$get in providers.

Please pay attention to the comments after the 2 lines.

.box1 {
    display: block;
    padding: 10px;
    margin-bottom: 100px; /* SIMPLY SET THIS PROPERTY AS MUCH AS YOU WANT. This changes the space below box1 */

How about the Intersection Observer API? This avoids the potential sluggishness from using the scroll event.

HTML

<nav class="navbar-fixed-top">Navbar</nav>
<main>
  <div class="content">Some content</div>
</main>

CSS

.navbar-fixed-top--scrolled changes the nav bar background color. It's added to the nav bar when the content div is no longer 100% visible as we scroll down.

.navbar-fixed-top {
  position: sticky;
  top: 0;
  height: 60px;
}

.navbar-fixed-top--scrolled {
  /* change background-color to whatever you want */
  background-color: grey;
}

JS

Create the observer to determine when the content div fully intersects with the browser viewport.

The callback function is called:

• the first time the observer is initially asked to watch the target element
• when content div is no longer fully visible (due to threshold: 1)
• when content div becomes fully visible (due to threshold: 1)

isIntersecting indicates whether the content div (the target element) is fully intersecting with the observer's root (the browser viewport by default).

// callback function to be run whenever threshold is crossed in one direction or the other
const callback = (entries, observer) => {
  const entry = entries[0];
  
  // toggle class depending on if content div intersects with viewport
  const navBar = document.querySelector('.navbar-fixed-top');
  navBar.classList.toggle('navbar-fixed-top--scrolled', !entry.isIntersecting);
}

// options controls circumstances under which the observer's callback is invoked
const options = {
  // no root provided - by default browser viewport used to check target visibility
  // only detect if target element is fully visible or not
  threshold: [1]
};

const io = new IntersectionObserver(callback, options);

// observe content div 
const target = document.querySelector('.content');
io.observe(target);

IntersectionObserver options

The nav bar currently changes background color when the content div starts moving off the screen.

If we want the background to change as soon as the user scrolls, we can use the rootMargin property (top, right, bottom, left) and set the top margin to negative the height of the nav bar (60px in our case).

const options = {
  rootMargin: "-60px 0px 0px 0px",
  threshold: [1]
};

You can see all the above in action on CodePen. Kevin Powell also has a good explanation on this (Github & YouTube).

I think you are converting the data a bit more than you need to. Once you create the buffer with the proper encoding, you just need to write the buffer to the file.

var base64Data = req.rawBody.replace(/^data:image\/png;base64,/, "");

require("fs").writeFile("out.png", base64Data, 'base64', function(err) {
  console.log(err);
});

new Buffer(..., 'base64') will convert the input string to a Buffer, which is just an array of bytes, by interpreting the input as a base64 encoded string. Then you can just write that byte array to the file.

Update

As mentioned in the comments, req.rawBody is no longer a thing. If you are using express/connect then you should use the bodyParser() middleware and use req.body, and if you are doing this using standard Node then you need to aggregate the incoming data event Buffer objects and do this image data parsing in the end callback.

Please use the below code. It will help you to get the incoming number with other call details.

and in your manifest request for following permissions:

It's not suitable for every situation, because not all items can have a non-proportional maximum, but slapping a good ol' max-width on the offending element/container can put it back in line.

int is a primitive data type. Integer is a wrapper class. It can store int data as objects.

What does it mean to "unwrap the instance"? Why is it necessary?

As far as I can work out (this is very new to me, too)...

The term "wrapped" implies we should think of an Optional variable as a present, wrapped in shiny paper, which might (sadly!) be empty.

When "wrapped", the value of an Optional variable is an enum with two possible values (a little like a Boolean). This enum describes whether the variable holds a value (Some(T)), or not (None).

If there is a value, this can be obtained by "unwrapping" the variable (obtaining the T from Some(T)).

How is john!.apartment = number73 different from john.apartment = number73? (Paraphrased)

If you write the name of an Optional variable (eg text john, without the !), this refers to the "wrapped" enum (Some/None), not the value itself (T). So john isn't an instance of Person, and it doesn't have an apartment member:

john.apartment
// 'Person?' does not have a member named 'apartment'

The actual Person value can be unwrapped in various ways:

• "forced unwrapping": john! (gives the Person value if it exists, runtime error if it is nil)
• "optional binding": if let p = john { println(p) } (executes the println if the value exists)
• "optional chaining": john?.learnAboutSwift() (executes this made-up method if the value exists)

I guess you choose one of these ways to unwrap, depending upon what should happen in the nil case, and how likely that is. This language design forces the nil case to be handled explicitly, which I suppose improves safety over Obj-C (where it is easy to forget to handle the nil case).

Update:

The exclamation mark is also used in the syntax for declaring "Implicitly Unwrapped Optionals".

In the examples so far, the john variable has been declared as var john:Person?, and it is an Optional. If you want the actual value of that variable, you must unwrap it, using one of the three methods above.

If it were declared as var john:Person! instead, the variable would be an Implicitly Unwrapped Optional (see the section with this heading in Apple's book). There is no need to unwrap this kind of variable when accessing the value, and john can be used without additional syntax. But Apple's book says:

Implicitly unwrapped optionals should not be used when there is a possibility of a variable becoming nil at a later point. Always use a normal optional type if you need to check for a nil value during the lifetime of a variable.

Update 2:

The article "Interesting Swift Features" by Mike Ash gives some motivation for optional types. I think it is great, clear writing.

Update 3:

Another useful article about the implicitly unwrapped optional use for the exclamation mark: "Swift and the Last Mile" by Chris Adamson. The article explains that this is a pragmatic measure by Apple used to declare the types used by their Objective-C frameworks which might contain nil. Declaring a type as optional (using ?) or implicitly unwrapped (using !) is "a tradeoff between safety and convenience". In the examples given in the article, Apple have chosen to declare the types as implicitly unwrapped, making the calling code more convenient, but less safe.

Perhaps Apple might comb through their frameworks in the future, removing the uncertainty of implicitly unwrapped ("probably never nil") parameters and replacing them with optional ("certainly could be nil in particular [hopefully, documented!] circumstances") or standard non-optional ("is never nil") declarations, based on the exact behaviour of their Objective-C code.

I found git here

C:\Users\<User>\AppData\Local\GitHubDesktop\app-0.5.8\resources\app\git\cmd\git.exe

You have to write file name (git.exe) in the end of path otherwise it will give an error=5

Or you can check here also.

C:\Program Files\Git\bin\git.exe

an easiest way which i used and worked well

date('Y-m-d', strtotime('-1 year'));

this worked perfect.. hope this will help someone else too.. :)

Updated for Apache 2.4, for non-systemd (e.g., CentOS 6.x, Amazon Linux AMI) and for systemd (e.g., CentOS 7.x):

There are two ways of having the apache process reload the configuration, depending on what you want done with its current threads, either advise to exit when idle, or killing them directly.

Note that Apache recommends using apachectl -k as the command, and for systemd, the command is replaced by httpd -k

apachectl -k graceful or httpd -k graceful

Apache will advise its threads to exit when idle, and then apache reloads the configuration (it doesn't exit itself), this means statistics are not reset.

apachectl -k restart or httpd -k restart

This is similar to stop, in that the process kills off its threads, but then the process reloads the configuration file, rather than killing itself.

For beginners: To create your .bash_profile file in your home directory on MacOS, run:

nano ~/.bash_profile

Then you can paste in the following:

https://gist.github.com/mocon/0baf15e62163a07cb957888559d1b054

As you can see, it includes some example aliases and an environment variable at the bottom.

One you're done making your changes, follow the instructions at the bottom of the Nano editor window to WriteOut (Ctrl-O) and Exit (Ctrl-X). Then quit your Terminal and reopen it, and you will be able to use your newly defined aliases and environment variables.

You can do multicolor outputs without any external programs.

@echo off
SETLOCAL EnableDelayedExpansion
for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (

)

call :ColorText 0b "red"
echo(
call :ColorText 19 "yellow"
call :ColorText 2F "black"
call :ColorText 4e "white"

goto :eof

:ColorText
echo off
<nul set /p ".=%DEL%" > "%~2"
findstr /v /a:%1 /R "^$" "%~2" nul
del "%~2" > nul 2>&1
goto :eof

It uses the color feature of the findstr command.

Findstr can be configured to output line numbers or filenames in a defined color.
So I first create a file with the text as filename, and the content is a single <backspace> character (ASCII 8).
Then I search all non empty lines in the file and in nul, so the filename will be output in the correct color appended with a colon, but the colon is immediatly removed by the <backspace>.

EDIT: One year later ... all characters are valid

@echo off
setlocal EnableDelayedExpansion
for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (
  set "DEL=%%a"
)

rem Prepare a file "X" with only one dot
<nul > X set /p ".=."

call :color 1a "a"
call :color 1b "b"
call :color 1c "^!<>&| %%%%"*?"
exit /b

:color
set "param=^%~2" !
set "param=!param:"=\"!"
findstr /p /A:%1 "." "!param!\..\X" nul
<nul set /p ".=%DEL%%DEL%%DEL%%DEL%%DEL%%DEL%%DEL%"
exit /b

This uses the rule for valid path/filenames.
If a \..\ is in the path the prefixed elemet will be removed completly and it's not necessary that this element contains only valid filename characters.

This is a paragraph option. Go to Window>Paragraph then a small window will pop up. You will have two buttons on the bottom. One with a arrow on the left of P and one on the right. Select the right one.

To switch between different images when the ImageButton is clicked I used a boolean like this:

ImageButton imageButton;
boolean buttonOn;

imageButton.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View v) {
         if (!buttonOn) {
             buttonOn = true;
             imageButton.setBackground(getResources().getDrawable(R.drawable.button_is_on)); 
         } else {
             buttonOn = false;
             imageButton.setBackground(getResources().getDrawable(R.drawable.button_is_off));
         }
     }
});

# indicates that the following line is a preprocessor directive and should be processed by the preprocessor before compilation by the compiler.

So, #include is a preprocessor directive that tells the preprocessor to include header files in the program.

< > indicate the start and end of the file name to be included.

iostream is a header file that contains functions for input/output operations (cin and cout).

Now to sum it up C++ to English translation of the command, #include <iostream> is:

Dear preprocessor, please include all the contents of the header file iostream at the very beginning of this program before compiler starts the actual compilation of the code.

I think it's worth mentioning how the Underscore's _.each() works internally. The _.each(list, iteratee) checks if the passed list is an array object, or an object.

In the case that the list is an array, iteratee arguments will be a list element and index as in the following example:

var a = ['I', 'like', 'pancakes', 'a', 'lot', '.'];
_.each( a, function(v, k) { console.log( k + " " + v); });

0 I
1 like
2 pancakes
3 a
4 lot
5 .

On the other hand, if the list argument is an object the iteratee will take a list element and a key:

var o = {name: 'mike', lastname: 'doe', age: 21};
_.each( o, function(v, k) { console.log( k + " " + v); });

name mike
lastname doe
age 21

For reference this is the _.each() code from Underscore.js 1.8.3

_.each = _.forEach = function(obj, iteratee, context) {
   iteratee = optimizeCb(iteratee, context);
   var i, length;
   if (isArrayLike(obj)) {
      for (i = 0, length = obj.length; i < length; i++) {
         iteratee(obj[i], i, obj);
      }
   } else {
      var keys = _.keys(obj);
      for (i = 0, length = keys.length; i < length; i++) {
         iteratee(obj[keys[i]], keys[i], obj);
      }
   }
   return obj;
};

$host.version is just plain wrong/unreliable. This gives you the version of the hosting executable (powershell.exe, powergui.exe, powershell_ise.exe, powershellplus.exe etc) and not the version of the engine itself.

The engine version is contained in $psversiontable.psversion. For PowerShell 1.0, this variable does not exist, so obviously if this variable is not available it is entirely safe to assume the engine is 1.0, obviously.

Where do you want to see the output?

Messages being output via Debug.Print will be displayed in the immediate window which you can open by pressing Ctrl+G.

You can also Activate the so called Immediate Window by clicking View -> Immediate Window on the VBE toolbar

Seaborn's barplot returns an axis-object (not a figure). This means you can do the following:

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt

fake = pd.DataFrame({'cat': ['red', 'green', 'blue'], 'val': [1, 2, 3]})
ax = sns.barplot(x = 'val', y = 'cat', 
              data = fake, 
              color = 'black')
ax.set(xlabel='common xlabel', ylabel='common ylabel')
plt.show()

The most idiomatic way to do this is to use symbols. For example, instead of:

enum {
  FOO,
  BAR,
  BAZ
}

myFunc(FOO);

...you can just use symbols:

# You don't actually need to declare these, of course--this is
# just to show you what symbols look like.
:foo
:bar
:baz

my_func(:foo)

This is a bit more open-ended than enums, but it fits well with the Ruby spirit.

Symbols also perform very well. Comparing two symbols for equality, for example, is much faster than comparing two strings.

Why would you want to override variables when you could easily reassign them in the subClasses.

I follow this pattern to work around the language design. Assume a case where you have a weighty service class in your framework which needs be used in different flavours in multiple derived applications.In that case , the best way to configure the super class logic is by reassigning its 'defining' variables.

public interface ExtensibleService{
void init();
}

public class WeightyLogicService implements ExtensibleService{
    private String directoryPath="c:\hello";

    public void doLogic(){
         //never forget to call init() before invocation or build safeguards
         init();
       //some logic goes here
   }

   public void init(){}    

}

public class WeightyLogicService_myAdaptation extends WeightyLogicService {
   @Override
   public void init(){
    directoryPath="c:\my_hello";
   }

}

The default scope is package-private. All classes in the same package can access the method/field/class. Package-private is stricter than protected and public scopes, but more permissive than private scope.

strtok can be very dangerous. It is not thread safe. Its intended use is to be called over and over in a loop, passing in the output from the previous call. The strtok function has an internal variable that stores the state of the strtok call. This state is not unique to each thread - it is global. If any other code uses strtok in another thread, you get problems. Not the kind of problems you want to track down either!

I'd recommend looking for a regex implementation, or using sscanf to pull apart the string.

Try this:

char strprint[256];
char text[256];
strcpy(text, "My string to test");
while ( sscanf( text, "%s %s", strprint, text) > 0 ) {
   printf("token: %s\n", strprint);
}

Note: The 'text' string is destroyed as it's separated. This may not be the preferred behaviour =)

The + character has a special meaning in a URL => it means whitespace - . If you want to use the literal + sign, you need to URL encode it to %2b:

body=Hi+there%2bHello+there

Here's an example of how you could properly generate URLs in .NET:

var uriBuilder = new UriBuilder("https://mail.google.com/mail");

var values = HttpUtility.ParseQueryString(string.Empty);
values["view"] = "cm";
values["tf"] = "0";
values["to"] = "[email protected]";
values["su"] = "some subject";
values["body"] = "Hi there+Hello there";

uriBuilder.Query = values.ToString();

Console.WriteLine(uriBuilder.ToString());

The result

https://mail.google.com:443/mail?view=cm&tf=0&to=someemail%40somedomain.com&su=some+subject&body=Hi+there%2bHello+there

You're right that you should use the Dispatcher to update controls on the UI thread, and also right that long-running processes should not run on the UI thread. Even if you run the long-running process asynchronously on the UI thread, it can still cause performance issues.

It should be noted that Dispatcher.CurrentDispatcher will return the dispatcher for the current thread, not necessarily the UI thread. I think you can use Application.Current.Dispatcher to get a reference to the UI thread's dispatcher if that's available to you, but if not you'll have to pass the UI dispatcher in to your background thread.

Typically I use the Task Parallel Library for threading operations instead of a BackgroundWorker. I just find it easier to use.

For example,

Task.Factory.StartNew(() => 
    SomeObject.RunLongProcess(someDataObject));

where

void RunLongProcess(SomeViewModel someDataObject)
{
    for (int i = 0; i <= 1000; i++)
    {
        Thread.Sleep(10);

        // Update every 10 executions
        if (i % 10 == 0)
        {
            // Send message to UI thread
            Application.Current.Dispatcher.BeginInvoke(
                DispatcherPriority.Normal,
                (Action)(() => someDataObject.ProgressValue = (i / 1000)));
        }
    }
}

IEnumerable is read-only and List is not.

Im not a java developer but was using a java app to test a RESTful API. In order for me to fix the error I had to install the intermediate certificates in the webserver in order to make the error go away. I was using lighttpd, the original certificate was installed on an IIS server. Hope it helps. These were the certificates I had missing on the server.

• UTNAddTrustServer_CA.crt
• AddTrustExternalCARoot.crt

You can do it on main.storyboard in about 2 seconds.

5. Change "background"

Was facing the same issue however it got resolved by cleaning up the git repository (Clean untracked files using "git clean").

To determine which line something is on you have to search all the code for the code that occupies the particular line of interest and count the "\n" characters from the top to this of interest and add 1.

I am actually doing this very thing in an application I am writing. It is a best practices validator for HTML and is still heavily under development, but the error output process that you would be interested in is complete.

To find all files modified in the last 24 hours (last full day) in a particular specific directory and its sub-directories:

find /directory_path -mtime -1 -ls

Should be to your liking

The - before 1 is important - it means anything changed one day or less ago. A + before 1 would instead mean anything changed at least one day ago, while having nothing before the 1 would have meant it was changed exacted one day ago, no more, no less.

You must use a more recent version of tomcat which has support for JDK 8.

I can confirm that apache-tomcat-7.0.35 does NOT have support for JDK8, I can also confirm that apache-tomcat-7.0.50 DOES have support for JDK8.

The easiest solution is to use numpy.insert().

The Advantage of np.insert() over np.append is that you can insert the new columns into custom indices.

import numpy as np

X = np.arange(20).reshape(10,2)

X = np.insert(X, [0,2], np.random.rand(X.shape[0]*2).reshape(-1,2)*10, axis=1)

You need to control the opening of sub forms from a main form.

In my case I'm opening a Login window first before I launch my form1. I control everything from Program.cs. Set up a validation flag in Program.cs. Open Login window from Program.cs. Control then goes to login window. Then if the validation is good, set the validation flag to true from the login window. Now you can safely close the login window. Control returns to Program.cs. If the validation flag is true, open form1. If the validation flag is false, your application will close.

In Program.cs:

   static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        /// 

        //Validation flag
        public static bool ValidLogin = false;

        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);


            Application.Run(new Login());

            if (ValidLogin)
            {
                Application.Run(new Form1());
            }
        }

    }

In Login.cs:

       private void btnOK_Click(object sender, EventArgs e)
        {
            if (txtUsername.Text == "x" && txtPassword.Text == "x")
            {
                Program.ValidLogin = true;
                this.Close();
            }
            else
            {
                MessageBox.Show("Username or Password are incorrect.");
            }
        }

        private void btnExit_Click(object sender, EventArgs e)
        {
            Application.Exit();
        }

You can use sort() function. sort() exists in algorithm header file

        #include<bits/stdc++.h>
        using namespace std;


        int main()
        {
            ios::sync_with_stdio(false);
            string str = "sharlock";

            sort(str.begin(), str.end());
            cout<<str<<endl;

            return 0;
        }

Output:

achklors

Use this also

NSString *ChkStr = [MyString substringWithRange:NSMakeRange(5, 26)];

Note - Your NSMakeRange(start, end) should be NSMakeRange(start, end- start);

You can use Environment.Exit(0); and Application.Exit

Environment.Exit(0) is cleaner.

{
  public ComparableTuple(X x, Y y) {
    super(x, y);
  }

  /**
   * Implements lexicographic order
   */
  public int compareTo(ComparableTuple<X, Y> other) {
    int d = this.x.compareTo(other.x);
    if (d == 0)
      return this.y.compareTo(other.y);

1. Dowload the binaries from the web source. The Apache Commos are in: [http://commons.apache.org/components.html][1] In this case, you must select the "Logging" in the Components menu and follow the link to downloads in the Releases part. Direct URL: [http://commons.apache.org/proper/commons-logging/download_logging.cgi][2] For me, the correct download was the file: commons-logging-1.2-bin.zip from the Binaries.

2. Unzip downloaded content. Now, you can see several jar files inside the directory created from the zip file.

3. Add the library to the project. Right click in the project, select Properties and click in Libraries (in the left side). Click the button "Add Jar/Folder". Go to the previously unzipped contents and select the properly jar file. Clic in "Open" and click in"Ok". The library has been loaded!

Webstorm 11 and 2016.2.3

Enable Node.js Core library in Webstorm settings.

for /l is your friend:

for /l %x in (1, 1, 100) do echo %x

Starts at 1, steps by one, and finishes at 100.

Use two %s if it's in a batch file

for /l %%x in (1, 1, 100) do echo %%x

(which is one of the things I really really hate about windows scripting)

If you have multiple commands for each iteration of the loop, do this:

for /l %x in (1, 1, 100) do (
   echo %x
   copy %x.txt z:\whatever\etc
)

or in a batch file

for /l %%x in (1, 1, 100) do (
   echo %%x
   copy %%x.txt z:\whatever\etc
)

Key:
/l denotes that the for command will operate in a numerical fashion, rather than operating on a set of files
%x is the loops variable
(starting value, increment of value, end condition[inclusive] )

Try this: https://docs.oracle.com/javase/1.5.0/docs/api/java/lang/String.html#replace%28java.lang.CharSequence,%20java.lang.CharSequence%29

String a = "HelloBrother How are you!";
String r = a.replace("HelloBrother","Brother");

System.out.println(r);

This would print out "Brother How are you!"

Try the following query:

collection.update(
  { _id: id },
  { $pull: { 'contact.phone': { number: '+1786543589455' } } }
);

It will find document with the given _id and remove the phone +1786543589455 from its contact.phone array.

You can use $unset to unset the value in the array (set it to null), but not to remove it completely.

SSH itself provides a means of communication, it does not know anything about directories. Since you can specify which remote command to execute (this is - by default - your shell), I'd start there.

For those who are using this format all the timme like me I did an extension method. I just wanted to share because I think it can be usefull to you.

     /// <summary>
    /// Convert a date to a human readable ISO datetime format. ie. 2012-12-12 23:01:12
    /// this method must be put in a static class. This will appear as an available function
    /// on every datetime objects if your static class namespace is declared.
    /// </summary>
    public static string ToIsoReadable(this DateTime dateTime)
    {
        return dateTime.ToString("yyyy-MM-dd HH':'mm':'ss");
    }

PHP does not have permissions to write on /tmp directory. You need to use chmod command to open /tmp permissions.

Both the regex and included files are good methods, and I frequently use those. But another alternative is to use a "named location", which is a useful approach in many situations — especially more complicated ones. The official "If is Evil" page shows essentially the following as a good way to do things:

error_page 418 = @common_location;
location /first/location/ {
    return 418;
}
location /second/location/ {
    return 418;
}
location @common_location {
    # The common configuration...
}

There are advantages and disadvantages to these various approaches. One big advantage to a regex is that you can capture parts of the match and use them to modify the response. Of course, you can usually achieve similar results with the other approaches by either setting a variable in the original block or using map. The downside of the regex approach is that it can get unwieldy if you want to match a variety of locations, plus the low precedence of a regex might just not fit with how you want to match locations — not to mention that there are apparently performance impacts from regexes in some cases.

The main advantage of including files (as far as I can tell) is that it is a little more flexible about exactly what you can include — it doesn't have to be a full location block, for example. But it's also just subjectively a bit clunkier than named locations.

Also note that there is a related solution that you may be able to use in similar situations: nested locations. The idea is that you would start with a very general location, apply some configuration common to several of the possible matches, and then have separate nested locations for the different types of paths that you want to match. For example, it might be useful to do something like this:

location /specialpages/ {
    # some config
    location /specialpages/static/ {
        try_files $uri $uri/ =404;
    }
    location /specialpages/dynamic/ {
        proxy_pass http://127.0.0.1;
    }
}

This prints the key combination directly to the image:

The first window shows 'z' pressed, the second shows 'ctrl' + 'z' pressed. When a key combination is used, a question mark appear.

Don't mess up with the question mark code, which is 63.

import numpy as np
import cv2

im = np.zeros((100, 300), np.uint8)
cv2.imshow('Keypressed', im)
while True:
  key = cv2.waitKey(0)
  im_c = im.copy()
  cv2.putText(
    im_c,
    f'{chr(key)} -> {key}',
    (10, 60), 
    cv2.FONT_HERSHEY_SIMPLEX, 
    1,
    (255,255,255),
    2)
  cv2.imshow('Keypressed', im_c)
  if key == 27: break # 'ESC'

Yet another option if you have it available: c# .net. In particular, the Microsoft.SqlServer.Management.Smo namespace.

I use code similar to the following in a Script Component of one of my SSIS packages.

var tableToTransfer = "someTable";
var transferringTableSchema = "dbo";

var srvSource = new Server("sourceServer");
var dbSource = srvSource.Databases["sourceDB"];

var srvDestination = new Server("destinationServer"); 
var dbDestination = srvDestination.Databases["destinationDB"];

var xfr = 
    new Transfer(dbSource) {
        DestinationServer = srvDestination.Name,
        DestinationDatabase = dbDestination.Name,
        CopyAllObjects = false,
        DestinationLoginSecure = true,
        DropDestinationObjectsFirst = true,
        CopyData = true
    };

xfr.Options.ContinueScriptingOnError = false; 
xfr.Options.WithDependencies = false; 

xfr.ObjectList.Add(dbSource.Tables[tableToTransfer,transferringTableSchema]);
xfr.TransferData();

I think I had to explicitly search for and add the Microsoft.SqlServer.Smo library to the references. But outside of that, this has been working out for me.

Update: The namespace and libraries were more complicated than I remembered.

For libraries, add references to:

• Microsoft.SqlServer.Smo.dll
• Microsoft.SqlServer.SmoExtended.dll
• Microsoft.SqlServer.ConnectionInfo.dll
• Microsoft.SqlServer.Management.Sdk.Sfc.dll

For the Namespaces, add:

• Microsoft.SqlServer.Management.Common
• Microsoft.SqlServer.Management.Smo

Additionally, if you want to use the filter in your controller the same way you do it here:

<div ng-repeat="item in items | filter:criteriaMatch(criteria)">
  {{ item }}
</div>

You could do something like:

var filteredItems =  $scope.$eval('items | filter:filter:criteriaMatch(criteria)');

faster way (without pyspark.sql.functions)

    df.filter((df.d<5)&((df.col1 != df.col3) |
                    (df.col2 != df.col4) & 
                    (df.col1 ==df.col3)))\
    .show()

It took me a couple hours to figure this out but I finally got it to work using CNTLM and afterwards got it to work with just a pip config file. Here is how I got it work with the pip config file...

Solution:

1. In Windows navigate to your user profile directory (Ex. C:\Users\Sync) and create a folder named "pip"

2. Create a file named "pip.ini" in this directory (Ex. C:\Users\Sync\pip\pip.ini) and enter the following into it:

    [global]
    trusted-host = pypi.python.org
                   pypi.org
                   files.pythonhosted.org
    proxy = http://[domain name]%5C[username]:[password]@[proxy address]:[proxy port]

Replace [domain name], [username], [password], [proxy address] and [proxy port] with your own information.

Note, if your [domain name], [username] or [password] has special characters, you have to percent-encode | encode them.

3. At this point I was able to run "pip install" without any issues.

Hopefully this works for others too!

P.S.: This may pose a security concern because of having your password stored in plain text. If this is an issue, consider setting up CNTLM using this article (allows using hashed password instead of plain text). Afterwards set proxy = 127.0.0.1:3128in the "pip.ini" file mentioned above.

Quick fix, add this in your options:

curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false)

Now you have no idea what host you're actually connecting to, because cURL will not verify the certificate in any way. Hope you enjoy man-in-the-middle attacks!

Or just add it to your current function:

/**
 * Get a web file (HTML, XHTML, XML, image, etc.) from a URL.  Return an
 * array containing the HTTP server response header fields and content.
 */
function get_web_page( $url )
{
    $options = array(
        CURLOPT_RETURNTRANSFER => true,     // return web page
        CURLOPT_HEADER         => false,    // don't return headers
        CURLOPT_FOLLOWLOCATION => true,     // follow redirects
        CURLOPT_ENCODING       => "",       // handle all encodings
        CURLOPT_USERAGENT      => "spider", // who am i
        CURLOPT_AUTOREFERER    => true,     // set referer on redirect
        CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
        CURLOPT_TIMEOUT        => 120,      // timeout on response
        CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
        CURLOPT_SSL_VERIFYPEER => false     // Disabled SSL Cert checks
    );

    $ch      = curl_init( $url );
    curl_setopt_array( $ch, $options );
    $content = curl_exec( $ch );
    $err     = curl_errno( $ch );
    $errmsg  = curl_error( $ch );
    $header  = curl_getinfo( $ch );
    curl_close( $ch );

    $header['errno']   = $err;
    $header['errmsg']  = $errmsg;
    $header['content'] = $content;
    return $header;
}

If it says the API key is listed as a header, more than likely you need to set it in the headers option of your http request. Normally something like this :

headers: {'Authorization': '[your API key]'}

Here is an example from another Question

$http({method: 'GET', url: '[the-target-url]', headers: {
  'Authorization': '[your-api-key]'}
});

Edit : Just saw you wanted to store the response in a variable. In this case I would probably just use AJAX. Something like this :

$.ajax({ 
   type : "GET", 
   url : "[the-target-url]", 
   beforeSend: function(xhr){xhr.setRequestHeader('Authorization', '[your-api-key]');},
   success : function(result) { 
       //set your variable to the result 
   }, 
   error : function(result) { 
     //handle the error 
   } 
 }); 

I got this from this question and I'm at work so I can't test it at the moment but looks solid

Edit 2: Pretty sure you should be able to use this line :

headers: {'Authorization': '[your API key]'},

instead of the beforeSend line in the first edit. This may be simpler for you

you can access the children of a vuejs component with this.$children. if you want to use the query selector on the current component instance then this.$el.querySelector(...)

just doing a simple console.log(this) will show you all the properties of a vue component instance.

additionally if you know the element you want to access in your component, you can add the v-el:uniquename directive to it and access it via this.$els.uniquename

Firstly, the below method doesn't compile as it is missing the return type and it should be Long.MAX_VALUE in place of Long.Max_value.

public static boolean isBiggerThanMaxLong(long value) {
      return value > Long.Max_value;
}

The above method can never return true as you are comparing a long value with Long.MAX_VALUE , see the method signature you can pass only long there.Any long can be as big as the Long.MAX_VALUE, it can't be bigger than that.

You can try something like this with BigInteger class :

public static boolean isBiggerThanMaxLong(BigInteger l){
    return l.compareTo(BigInteger.valueOf(Long.MAX_VALUE))==1?true:false;
}

The below code will return true :

BigInteger big3 = BigInteger.valueOf(Long.MAX_VALUE).
                  add(BigInteger.valueOf(Long.MAX_VALUE));
System.out.println(isBiggerThanMaxLong(big3)); // prints true

If you need to print it and don't need a newline, you can use:

printf $(md5sum filename)

How about something like this...

Dim rs As RecordSet
Set rs = Currentdb.OpenRecordSet("SELECT PictureLocation, ID FROM MyAccessTable;")

Do While Not rs.EOF
   Debug.Print rs("PictureLocation") & " - " & rs("ID")
   rs.MoveNext
Loop

Here It is actually returning tuple.

If you execute this code in Python 3:

def get():
    a = 3
    b = 5
    return a,b
number = get()
print(type(number))
print(number)

Output :

<class 'tuple'>
(3, 5)

But if you change the code line return [a,b] instead of return a,b and execute :

def get():
    a = 3
    b = 5
    return [a,b]
number = get()
print(type(number))
print(number)

Output :

<class 'list'>
[3, 5]

It is only returning single object which contains multiple values.

There is another alternative to return statement for returning multiple values, use yield( to check in details see this What does the "yield" keyword do in Python?)

Sample Example :

def get():
    for i in range(5):
        yield i
number = get()
print(type(number))
print(number)
for i in number:
    print(i)

Output :

<class 'generator'>
<generator object get at 0x7fbe5a1698b8>

.bash_profile is loaded for a "login shell". I am not sure what that would be on OS X, but on Linux that is either X11 or a virtual terminal.

.bashrc is loaded every time you run Bash. That is where you should put stuff you want loaded whenever you open a new Terminal.app window.

I personally put everything in .bashrc so that I don't have to restart the application for changes to take effect.

I think a most simple solution would be as follows:

1. Make one implementation of assigning a value to some variable i.e. via function or setter.
2. Create a class variable (static working: boolean) in the class where this function exists and every time you call the function, simply make it true whichever you like. Within the function, if the value of working is true, then simply return right away without doing anything. else, perform the task you want. Make sure to change this variable to false once the task is completed i.e. at the end of the line of codes or within the subscribe method when you are done assigning values!

The Main method is the Entry point of your application. If you checkout via ildasm then

.method private hidebysig static void  Main(string[] args) cil managed
{
  .entrypoint

This is what helps in calling the method

The arguments are passed as say C:\AppName arg1 arg2 arg3

I was getting the 400 Bad Request error, even after setting:

contentType: "application/json",
dataType: "json"

The issue was with the type of a property passed in the json object, for the data property in the ajax request object.
To figure out the issue, I added an error handler and then logged the error to the console. Console log will clearly show validation errors for the properties if any.

This was my initial code:

var data = {
    "TestId": testId,
    "PlayerId": parseInt(playerId),
    "Result": result
};

var url = document.location.protocol + "//" + document.location.host + "/api/tests"
$.ajax({
    url: url,
    method: "POST",
    contentType: "application/json",
    data: JSON.stringify(data), // issue with a property type in the data object
    dataType: "json",
    error: function (e) {
        console.log(e); // logging the error object to console
    },
    success: function () {
        console.log('Success saving test result');
    }
});

Now after making the request, I checked the console tab in the browser development tool.
It looked like this:

responseJSON.errors[0] clearly shows a validation error: The JSON value could not be converted to System.String. Path: $.TestId, which means I have to convert TestId to a string in the data object, before making the request.

Changing the data object creation like below fixed the issue for me:

var data = {
        "TestId": String(testId), //converting testId to a string
        "PlayerId": parseInt(playerId),
        "Result": result
};

I assume other possible errors could also be identified by logging and inspecting the error object.

try

id == list[pos].getItemNumber()

instead of

id.equals(list[pos].getItemNumber()

byte[] conv = new byte[4];
conv[3] = (byte) input & 0xff;
input >>= 8;
conv[2] = (byte) input & 0xff;
input >>= 8;
conv[1] = (byte) input & 0xff;
input >>= 8;
conv[0] = (byte) input;

What about detached or unrelated shells and code [args] support?

While other answers talk about how to configure and use the VScode integrated WSL bash terminal support, they don't solve the problem of "detached shells": shells which were not launched from within VScode, or which somehow get "disconnected" from the VScode server instance associated with the IDE.

Such shells can give errors like:

Command is only available in WSL or inside a Visual Studio Code terminal.

or...

Unable to connect to VS Code server. Error in request

Here's a script which makes it easy to solve this problem.

I use this daily to connect shells in a tmux session with a specific VScode server instance, or to fix an integrated shell that's become detached from its hosting IDE.

#!/bin/bash
# codesrv-connect
#
#  Purpose:
#     Copies the vscode connection environment from one shell to another, so that you can use the
#     vscode integrated terminal's "code [args]" command to communicate with that instance of vscode
#     from an unrelated shell.
#
#  Usage:
#    1.  Open an integrated terminal in vscode, and run codesrv-connect
#    2.  In the target shell, cd to the same directory and run
#       ". .codesrv-connect", or follow the instruction printed by codesrv-connect.
#
#  Setup:
#    Put "codesrv-connect somewhere on your PATH (e.g. ~/bin)"
#
#  Cleanup:
#    - Delete abandoned .codesrv-connect files when their vscode sessions die.
#    - Do not add .codesrv-connect files to git repositories.
#
#  Notes:
#     The VSCODE_IPC_HOOK_CLI environment variable points to a socket which is rather volatile, while the long path for the 'code' alias is more stable: vscode doesn't change the latter even across a "code -r ." reload.  But the former is easily detached and so you need a fresh value if that happens.  This is what codesrv-connect does: it captures the value of these two and writes them to .codesrv-connect in the current dir.

    echo "ERROR: $VSCODE_IPC_HOOK_CLI not a socket. Dead session."
else
    export VSCODE_IPC_HOOK_CLI="$VSCODE_IPC_HOOK_CLI"
    alias code=$(which code)
    echo "Done: the 'code' command will talk to socket \"$VSCODE_IPC_HOOK_CLI\" now."
    echo "You can delete .codesrv-connect when the vscode server context dies, or reuse it in other shells until then."
fi

echo "# OK: run this to connect to vscode server in a destination shell:"
echo ". $PWD/.codesrv-connect"

I have used this before and I think in order to make sure credential persist and in a best secure way is

1. you can write them to the app config file using the ConfigurationManager class
2. securing the password using the SecureString class
3. then encrypting it using tools in the Cryptography namespace.

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

There is no single magic function to force a frame to a minimum or fixed size. However, you can certainly force the size of a frame by giving the frame a width and height. You then have to do potentially two more things: when you put this window in a container you need to make sure the geometry manager doesn't shrink or expand the window. Two, if the frame is a container for other widget, turn grid or pack propagation off so that the frame doesn't shrink or expand to fit its own contents.

Note, however, that this won't prevent you from resizing a window to be smaller than an internal frame. In that case the frame will just be clipped.

import Tkinter as tk

root = tk.Tk()
frame1 = tk.Frame(root, width=100, height=100, background="bisque")
frame2 = tk.Frame(root, width=50, height = 50, background="#b22222")

frame1.pack(fill=None, expand=False)
frame2.place(relx=.5, rely=.5, anchor="c")

root.mainloop()

This is a pretty hacky solution, but it's at least something(?). The idea is to use a CSS transform to rotate the contents of your page to quasi-portrait mode. Here's JavaScript (expressed in jQuery) code to get you started:

$(document).ready(function () {
  function reorient(e) {
    var portrait = (window.orientation % 180 == 0);
    $("body > div").css("-webkit-transform", !portrait ? "rotate(-90deg)" : "");
  }
  window.onorientationchange = reorient;
  window.setTimeout(reorient, 0);
});

The code expects the entire contents of your page to live inside a div just inside the body element. It rotates that div 90 degrees in landscape mode - back to portrait.

Left as an exercise to the reader: the div rotates around its centerpoint, so its position will probably need to be adjusted unless it's perfectly square.

Also, there's an unappealing visual problem. When you change orientation, Safari rotates slowly, then the top-level div snaps to 90degrees different. For even more fun, add

body > div { -webkit-transition: all 1s ease-in-out; }

to your CSS. When the device rotates, then Safari does, then the content of your page does. Beguiling!

KISS answer

Difference:

START_STICKY

the system will try to re-create your service after it is killed

START_NOT_STICKY

the system will not try to re-create your service after it is killed

Standard example:

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

You're right that the SD Card directory is /sdcard but you shouldn't be hard coding it. Instead, make a call to Environment.getExternalStorageDirectory() to get the directory:

File sdDir = Environment.getExternalStorageDirectory();

If you haven't done so already, you will need to give your app the correct permission to write to the SD Card by adding the line below to your Manifest:

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

If you are looking for a recursive version without using the json module:

def ordereddict_to_dict(value):
    for k, v in value.items():
        if isinstance(v, dict):
            value[k] = ordereddict_to_dict(v)
    return dict(value)

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
    GridViewRow row = (GridViewRow)GridView1.Rows[e.RowIndex];
    SqlCommand cmd = new SqlCommand("Delete From userTable (userName,age,birthPLace)");
    GridView1.DataBind();
}

This seems to be a little buggy in Pandas 0.23.4?

If there are np.nan values then this will throw an error as expected:

df['col'] = df['col'].astype(np.int64)

But doesn't change any values from float to int as I would expect if "ignore" is used:

df['col'] = df['col'].astype(np.int64,errors='ignore') 

It worked if I first converted np.nan:

df['col'] = df['col'].fillna(0).astype(np.int64)
df['col'] = df['col'].astype(np.int64)

Now I can't figure out how to get null values back in place of the zeroes since this will convert everything back to float again:

df['col']  = df['col'].replace(0,np.nan)

The thing about classes, and setting unencumbered global variables equal to some value within the class, is that what your global variable stores is actually the reference to the memory location the value is actually stored.

What you're seeing in your output is indicative of this.

Where you might be able to see the value and use print without issue on the initial global variables you used because of the str method and how print works, you won't be able to do this with lists, because what is stored in the elements within that list is just a reference to the memory location of the value -- read up on aliases, if you'd like to know more.

Additionally, when using lists and losing track of what is an alias and what is not, you might find you're changing the value of the original list element, if you change it in an alias list -- because again, when you set a list element equal to a list or element within a list, the new list only stores the reference to the memory location (it doesn't actually create new memory space specific to that new variable). This is where deepcopy comes in handy!

class list_benefits(object):
    def __init__(self):
        self.s1 = "More organized code"
        self.s2 = "More readable code"
        self.s3 = "Easier code reuse"

def build_sentence():
        obj=list_benefits()
        print obj.s1 + " is a benefit of functions!"
        print obj.s2 + " is a benefit of functions!"
        print obj.s3 + " is a benefit of functions!"

print build_sentence()

I know it is late answer, maybe some other folk can benefit If you still want to call by "attributes", you could use class with default constructor, and create an instance of the class as mentioned in other answers

What you are passing to GETNAME is the value of myInput, not the definition of myInput itself. The only way to do that is with a lambda expression, for example:

var nameofVar = GETNAME(() => myInput);

and indeed there are examples of that available. However! This reeks of doing something very wrong. I would propose you rethink why you need this. It is almost certainly not a good way of doing it, and forces various overheads (the capture class instance, and the expression tree). Also, it impacts the compiler: without this the compiler might actually have chosen to remove that variable completely (just using the stack without a formal local).

I want columns One and Two to shrink/grow to fit rather than being fixed.

Have you tried: flex-basis: auto

or this:

flex: 1 1 auto, which is short for:

• flex-grow: 1 (grow proportionally)
• flex-shrink: 1 (shrink proportionally)
• flex-basis: auto (initial size based on content size)

or this:

main > section:first-child {
    flex: 1 1 auto;
    overflow-y: auto;
}

main > section:nth-child(2) {
    flex: 1 1 auto;
    overflow-y: auto;
}

main > section:last-child {
    flex: 20 1 auto;
    display: flex;
    flex-direction: column;  
}

I was facing this same problem. Let me tell you how I solved it and achieved everything you all seem to be wanting.

Requirements:

1. Must have a button (or link) to a file - (or a generated memory stream)
2. Must click the button and have the file download

In my service, (I'm using Asp.net Web API), I have a controller returning an "HttpResponseMessage". I add a "StreamContent" to the response.Content field, set the headers to "application/octet-stream" and add the data as an attachment. I even give it a name "myAwesomeFile.xlsx"

response = Request.CreateResponse(HttpStatusCode.OK);
response.Content = new StreamContent(memStream);
response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment") { FileName = "myAwesomeFile.xlsx" };

Now here's the trick ;)

I am storing the base URL in a text file that I read into a variable in an Angular Value called "apiRoot". I do this by declaring it and then setting it on the "run" function of the Module, like so:

app.value('apiRoot', { url: '' });
app.run(function ($http, apiRoot) {
    $http.get('/api.txt').success(function (data) {
        apiRoot.url = data;
    });
});

That way I can set the URL in a text file on the server and not worry about "blowing it away" in an upload. (You can always change it later for security reasons - but this takes the frustration out of development ;) )

And NOW the magic:

All I'm doing is creating a link with a URL that directly hits my service endpoint and target's a "_blank".

<a ng-href="{{vm.getFileHref(FileId)}}" target="_blank" class="btn btn-default">&nbsp;Excel File</a>

the secret sauce is the function that sets the href. You ready for this?

vm.getFileHref = function (Id) {
    return apiRoot.url + "/datafiles/excel/" + Id;
}

Yep, that's it. ;)

Even in a situation where you are iterating over many records that have files to download, you simply feed the Id to the function and the function generates the url to the service endpoint that delivers the file.

Hope this helps!

Your formula is wrong. You probably meant something like:

=IF(AND(NOT(ISBLANK(Q2));NOT(ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Another equivalent:

=IF(NOT(OR(ISBLANK(Q2);ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Or even shorter:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";IF(Q2<=R2;"1";"0"))

OR EVEN SHORTER:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";--(Q2<=R2))

Without more details as to what the question is exactly asking, I am going to answer the title of the question,

Create an Array:

String[] myArray = new String[2];
int[] intArray = new int[2];

// or can be declared as follows
String[] myArray = {"this", "is", "my", "array"};
int[] intArray = {1,2,3,4};

Create an ArrayList:

ArrayList<String> myList = new ArrayList<String>();
myList.add("Hello");
myList.add("World");

ArrayList<Integer> myNum = new ArrayList<Integer>();
myNum.add(1);
myNum.add(2);

This means, create an ArrayList of String and Integer objects. You cannot use int because thats a primitive data types, see the link for a list of primitive data types.

Create a Stack:

Stack myStack = new Stack();
// add any type of elements (String, int, etc..)
myStack.push("Hello");
myStack.push(1);

Create an Queue: (using LinkedList)

Queue<String> myQueue = new LinkedList<String>();
Queue<Integer> myNumbers = new LinkedList<Integer>();
myQueue.add("Hello");
myQueue.add("World");
myNumbers.add(1);
myNumbers.add(2);

Same thing as an ArrayList, this declaration means create an Queue of String and Integer objects.

Update:

In response to your comment from the other given answer,

i am pretty confused now, why are using string. and what does <String> means

We are using String only as a pure example, but you can add any other object, but the main point is that you use an object not a primitive type. Each primitive data type has their own primitive wrapper class, see link for list of primitive data type's wrapper class.

I have posted some links to explain the difference between the two, but here are a list of primitive types

• byte
• short
• char
• int
• long
• boolean
• double
• float

Which means, you are not allowed to make an ArrayList of integer's like so:

ArrayList<int> numbers = new ArrayList<int>(); 
           ^ should be an object, int is not an object, but Integer is!
ArrayList<Integer> numbers = new ArrayList<Integer>();
            ^ perfectly valid

Also, you can use your own objects, here is my Monster object I created,

public class Monster {
   String name = null;
   String location = null;
   int age = 0;

public Monster(String name, String loc, int age) { 
   this.name = name;
   this.loc = location;
   this.age = age;
 }

public void printDetails() {
   System.out.println(name + " is from " + location +
                                     " and is " + age + " old.");
 }
} 

Here we have a Monster object, but now in our Main.java class we want to keep a record of all our Monster's that we create, so let's add them to an ArrayList

public class Main {
    ArrayList<Monster> myMonsters = new ArrayList<Monster>();

public Main() {
    Monster yetti = new Monster("Yetti", "The Mountains", 77);
    Monster lochness = new Monster("Lochness Monster", "Scotland", 20);

    myMonsters.add(yetti); // <-- added Yetti to our list
    myMonsters.add(lochness); // <--added Lochness to our list
  
    for (Monster m : myMonsters) {
        m.printDetails();
     }
   }

public static void main(String[] args) {
    new Main();
 }
}

(I helped my girlfriend's brother with a Java game, and he had to do something along those lines as well, but I hope the example was well demonstrated)

Even though there are many accepted answers, I think this way is also possible:

Create your 'servers' table as following :

CREATE TABLE `servers`
(
      id int(11) NOT NULL PRIMARY KEY auto_increment,
      server_name varchar(45) NOT NULL,
      online_status varchar(45) NOT NULL,
      _exchange varchar(45) NOT NULL, 
      disk_space varchar(45) NOT NULL,
      network_shares varchar(45) NOT NULL,
      date_time datetime NOT NULL DEFAULT CURRENT_TIMESTAMP
);

And your INSERT statement should be :

INSERT INTO servers (server_name, online_status, _exchange, disk_space, network_shares)
VALUES('m1', 'ONLINE', 'ONLINE', '100GB', 'ONLINE');

My Environment:

Core i3 Windows Laptop with 4GB RAM, and I did the above example on MySQL Workbench 6.2 (Version 6.2.5.0 Build 397 64 Bits)

The author appears to have taken a freemium approach to the font library and provides Black Tie to give different weights to the Font-Awesome library.

cfg_name_unique NOT LIKE '%categories%' 

still returns those two values, but maybe exclude them explicit:

SELECT *
    FROM developer_configurations_cms

This question has been answered but I feel I should also mention another potential cause. This is a direct result of coming across the same error message but for different reasons. If your list/s are empty the operation will not be performed. check your code for indents and typos

One of the reason I found was why it doesn't find a jar from repository might be because the .pom file for that particular jar might be missing or corrupt. Just correct it and try to load from local repository.

If you have PowerShell 5.0 or higher (pre-installed with Windows 10 and Windows Server 2016):

powershell Expand-Archive your.zip -DestinationPath your_destination

I think I got what I was looking for..

data.train <- read.table("Assign2.WineComplete.csv",sep=",",header=T)
fit <- rpart(quality ~ ., method="class",data=data.train)
plot(fit)
text(fit, use.n=TRUE)
summary(fit)

Genial arrow module exists

import arrow
utc = arrow.utcnow()
utc_yesterday = utc.shift(days=-1)
print(utc, '\n', utc_yesterday)

output:

Check this out,

body {
    background-color: black;
    background: url(img/bg.jpg) no-repeat center center fixed; 
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
}

Try with JQuery:

<script type="text/javascript">
function jquery_get_width_height()
{
    var imgWidth = $("#img").width();
    var imgHeight = $("#img").height();
    alert("JQuery -- " + "imgWidth: " + imgWidth + " - imgHeight: " + imgHeight);
}
</script>

or

<script type="text/javascript">
function javascript_get_width_height()
{
    var img = document.getElementById('img');
    alert("JavaSript -- " + "imgWidth: " + img.width + " - imgHeight: " + img.height);
}
</script>

"tty" originally meant "teletype" and "pty" means "pseudo-teletype".

In UNIX, /dev/tty* is any device that acts like a "teletype", ie, a terminal. (Called teletype because that's what we had for terminals in those benighted days.)

A pty is a pseudotty, a device entry that acts like a terminal to the process reading and writing there, but is managed by something else. They first appeared (as I recall) for X Window and screen and the like, where you needed something that acted like a terminal but could be used from another program.

This makes a nice Function....

If you are a slacker like me you might like to use the File::Slurp module. The read_dir function will reads directory contents into an array, removes the dots, and if needed prefix the files returned with the dir for absolute paths

my @paths = read_dir( '/path/to/dir', prefix => 1 ) ;

You can use:

<a href="http://www.WEBSITE_NAME.com"  target="_blank"> Website</a>

However the above make your site vulnerable to phishing attacks. You can prevent it from happening in some browsers by adding rel="noopener noreferrer" to your link. With this added, the above example becomes:

<a href="http://www.WEBSITE_NAME.com" rel="noopener noreferrer" target="_blank">Website.com</a>

CREATE UNIQUE INDEX foo ON table_name (field_name)

You have to remove duplicate values on that column before executes that sql. Any existing duplicate value on that column will lead you to mysql error 1062

This is what I ended up using a variation of, which checks for IE8 and below:

if (preg_match('/MSIE\s(?P<v>\d+)/i', @$_SERVER['HTTP_USER_AGENT'], $B) && $B['v'] <= 8) {
    // Browsers IE 8 and below
} else {
    // All other browsers
}

In addition to placeholder="your text" you could also do onclick="this.value='';

So it would look something like:

<input name="Name" value="Enter Your Name" onclick="this.value='';>

There is no need to use :checkbox, also replace #activelist with #inactivelist:

$('#inactivelist').change(function () {
    alert('changed');
 });

R has gotten to the point where the OS cannot allocate it another 75.1Mb chunk of RAM. That is the size of memory chunk required to do the next sub-operation. It is not a statement about the amount of contiguous RAM required to complete the entire process. By this point, all your available RAM is exhausted but you need more memory to continue and the OS is unable to make more RAM available to R.

Potential solutions to this are manifold. The obvious one is get hold of a 64-bit machine with more RAM. I forget the details but IIRC on 32-bit Windows, any single process can only use a limited amount of RAM (2GB?) and regardless Windows will retain a chunk of memory for itself, so the RAM available to R will be somewhat less than the 3.4Gb you have. On 64-bit Windows R will be able to use more RAM and the maximum amount of RAM you can fit/install will be increased.

If that is not possible, then consider an alternative approach; perhaps do your simulations in batches with the n per batch much smaller than N. That way you can draw a much smaller number of simulations, do whatever you wanted, collect results, then repeat this process until you have done sufficient simulations. You don't show what N is, but I suspect it is big, so try smaller N a number of times to give you N over-all.

You can add a sequence of numbers very easily with

data$ID <- seq.int(nrow(data))

If you are already using library(tidyverse), you can use

data <- tibble::rowid_to_column(data, "ID")

To make everything writable by the owner, read/execute by the group, and world executable:

chmod -R 0755

To make everything wide open:

chmod -R 0777

I am not sure about DO-WHILE IN MS SQL Server 2008 but you can change your WHILE loop logic, so as to USE like DO-WHILE loop.

Examples are taken from here: http://blog.sqlauthority.com/2007/10/24/sql-server-simple-example-of-while-loop-with-continue-and-break-keywords/

1. Example of WHILE Loop

   DECLARE @intFlag INT
   SET @intFlag = 1
   WHILE (@intFlag <=5)
   BEGIN
       PRINT @intFlag
       SET @intFlag = @intFlag + 1
   END
   GO
   

   ResultSet:

   1
   2
   3
   4
   5
   

2. Example of WHILE Loop with BREAK keyword

   DECLARE @intFlag INT
   SET @intFlag = 1
   WHILE (@intFlag <=5)
   BEGIN
       PRINT @intFlag
       SET @intFlag = @intFlag + 1
       IF @intFlag = 4
           BREAK;
   END
   GO
   

   ResultSet:

   1
   2
   3
   

3. Example of WHILE Loop with CONTINUE and BREAK keywords

   DECLARE @intFlag INT
   SET @intFlag = 1
   WHILE (@intFlag <=5)
   BEGIN
       PRINT @intFlag
       SET @intFlag = @intFlag + 1
       CONTINUE;
       IF @intFlag = 4 -- This will never executed
           BREAK;
   END
   GO
   

   ResultSet:

   1
   2
   3
   4
   5
   

But try to avoid loops at database level. Reference.

I think that you might get a little more performance if you tried this

DELETE FROM Table1
WHERE EXISTS (
  SELECT 1
  FROM Table2
  WHERE Table1.ID = Table2.ID
)

If you put the SQL strings in a properties file and then read that in you can keep the SQL strings in a plain text file.

That doesn't solve the SQL type issues, but at least it makes copying&pasting from TOAD or sqlplus much easier.
