There's a lot of great - complex - answers here. In my particular case i found a clean and simple fix for the logout. I have yet to test in Edge. On my page that I have logged in to, I have placed a logout link similar to this:

<a href="https://MyDomainHere.net/logout.html">logout</a>

And in the head of that logout.html page (which is also protected by the .htaccess) I have a page refresh similar to this:

<meta http-equiv="Refresh" content="0; url=https://logout:[email protected]/" />

Where you would leave the words "logout" in place to clear the username and password cached for the site.

I will admit that if multiple pages needed to be able to be directly logged in to from the beginning, each of those points of entry would need their own corresponding logout.html page. Otherwise you could centralize the logout by introducing an additional gatekeeper step into the process before the actual login prompt, requiring entry of a phrase to reach a destination of login.

I had a the same issue and after reading the above answers all I had to do was go to Build Settings > Code Signing > Provisioning Profile > None and was able to ran the app on my devices again. Hope this helps someone else out

If you need to call different functions for different ng-repeats on the same controller you can try something like this:

The directive:

var module = angular.module('testApp', [])
    .directive('onFinishRender', function ($timeout) {
    return {
        restrict: 'A',
        link: function (scope, element, attr) {
            if (scope.$last === true) {
            $timeout(function () {
                scope.$emit(attr.broadcasteventname ? attr.broadcasteventname : 'ngRepeatFinished');
            });
            }
        }
    }
});

In your controller, catch events with $on:

$scope.$on('ngRepeatBroadcast1', function(ngRepeatFinishedEvent) {
// Do something
});

$scope.$on('ngRepeatBroadcast2', function(ngRepeatFinishedEvent) {
// Do something
});

In your template with multiple ng-repeat

<div ng-repeat="item in collection1" on-finish-render broadcasteventname="ngRepeatBroadcast1">
    <div>{{item.name}}}<div>
</div>

<div ng-repeat="item in collection2" on-finish-render broadcasteventname="ngRepeatBroadcast2">
    <div>{{item.name}}}<div>
</div>

No value was specified for the AUTO_INCREMENT column, so MySQL assigned sequence numbers automatically. You can also explicitly assign NULL or 0 to the column to generate sequence numbers.

You can use the Dictionary data type in python. It's very very similar to the hash—and it also supports nesting, similar to the to nested hash.

Example:

dict = {'Name': 'Zara', 'Age': 7, 'Class': 'First'}
dict['Age'] = 8; # update existing entry
dict['School'] = "DPS School" # Add new entry

print ("dict['Age']: ", dict['Age'])
print ("dict['School']: ", dict['School'])

For more information, please reference this tutorial on the dictionary data type.

The usual WPF timer is the DispatcherTimer, which is not a control but used in code. It basically works the same way like the WinForms timer:

System.Windows.Threading.DispatcherTimer dispatcherTimer = new System.Windows.Threading.DispatcherTimer();
dispatcherTimer.Tick += dispatcherTimer_Tick;
dispatcherTimer.Interval = new TimeSpan(0,0,1);
dispatcherTimer.Start();


private void dispatcherTimer_Tick(object sender, EventArgs e)
{
  // code goes here
}

More on the DispatcherTimer can be found here

Result.data.Count will give you what you are looking for

 apigClient.getitemPost({}, body, {})

    .then(function(result){

        var dataoutput = result.data.Items[0];

        console.log(result.data.Count);
  }).catch( function(result){

});

Here is my contribution to the debate ... This returns a single array with the data separated and the headers listed. This works on the basis that CURL will return a headers chunk [ blank line ] data

curl_setopt($ch, CURLOPT_HEADER, 1); // we need this to get headers back
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, true);

// $output contains the output string
$output = curl_exec($ch);

$lines = explode("\n",$output);

$out = array();
$headers = true;

foreach ($lines as $l){
    $l = trim($l);

    if ($headers && !empty($l)){
        if (strpos($l,'HTTP') !== false){
            $p = explode(' ',$l);
            $out['Headers']['Status'] = trim($p[1]);
        } else {
            $p = explode(':',$l);
            $out['Headers'][$p[0]] = trim($p[1]);
        }
    } elseif (!empty($l)) {
        $out['Data'] = $l;
    }

    if (empty($l)){
        $headers = false;
    }
}

The difference is the value returned to the environment is 0 in the former case and 1 in the latter case:

$ ./prog_with_exit_0
$ echo $?
0
$

and

$ ./prog_with_exit_1
$ echo $?
1
$

Also note that the macros value EXIT_SUCCESS and EXIT_FAILURE used as an argument to exit function are implementation defined but are usually set to respectively 0 and a non-zero number. (POSIX requires EXIT_SUCCESS to be 0). So usually exit(0) means a success and exit(1) a failure.

An exit function call with an argument in main function is equivalent to the statement return with the same argument.

In case of WSS 3.0 recently I experienced same issue. It was because of column that was accessed from code was not present in the wss list.

While the answer of loeschg is absolutely correct I just wanna elaborate on it and give a solution for all IDE's (Eclipse, IntellJ and Android Studio) even if the errors differentiate slightly.

Prerequirements

Make sure that you've downloaded the latest extras as well as the Android 5.0 SDK via the SDK-Manager.

Android Studio

Open the build.gradle file of your app-module and change your compileSdkVersion to 21. It's basically not necessary to change the targetSdkVersion SDK-Version to 21 but it's recommended since you should always target the latest android Build-Version.
In the end you gradle-file will look like this:

android {
    compileSdkVersion 21
    // ...

    defaultConfig {
        // ...
        targetSdkVersion 21
    }
}

Be sure to sync your project afterwards.

Eclipse

When using the v7-appcompat in Eclipse you have to use it as a library project. It isn't enough to just copy the *.jar to your /libs folder. Please read this (click) step-by-step tutorial on developer.android.com in order to know how to import the project properly.

As soon as the project is imported, you'll realize that some folders in the /resfolder are red-underlined because of errors such as the following:

error: Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material'.
error: Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.*'
error: Error: No resource found that matches the given name: attr 'android:actionModeShareDrawable'.

Solution

The only thing you have to do is to open the project.properties file of the android-support-v7-appcompat and change the target from target=android-19 to target=android-21.
Afterwards just do a Project --> Clean... so that the changes take effect.

IntelliJ IDEA (not using Gradle)

Similiar to Eclipse it's not enough to use only the android-support-v7-appcompat.jar; you have to import the appcompat as a module. Read more about it on this StackO-Post (click).
(Note: If you're only using the .jar you'll get NoClassDefFoundErrors on Runtime)

When you're trying to build the project you'll face issues in the res/values-v** folders. Your message window will say something like the following:

Error:android-apt-compiler: [appcompat]  resource found that matches the given name: attr 'android:colorPrimary'.
Error:(75, -1) android-apt-compiler: [appcompat] C:\[Your Path]\sdk\extras\android\support\v7\appcompat\res\values-v21\styles_base.xml:75: error: Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.ActionButton'.
// and so on

Solution

Right click on appcompat module --> Open Module Settings (F4) --> [Dependency Tab] Select Android API 21 Platform from the dropdown --> Apply

Then just rebuild the project (Build --> Rebuild Project) and you're good to go.

Because your question is phrased regarding your error message and not whatever your function is trying to accomplish, I will address the error.

- is the 'binary operator' your error is referencing, and either CurrentDay or MA (or both) are non-numeric.

A binary operation is a calculation that takes two values (operands) and produces another value (see wikipedia for more). + is one such operator: "1 + 1" takes two operands (1 and 1) and produces another value (2). Note that the produced value isn't necessarily different from the operands (e.g., 1 + 0 = 1).

R only knows how to apply + (and other binary operators, such as -) to numeric arguments:

> 1 + 1
[1] 2
> 1 + 'one'
Error in 1 + "one" : non-numeric argument to binary operator

When you see that error message, it means that you are (or the function you're calling is) trying to perform a binary operation with something that isn't a number.

EDIT:

Your error lies in the use of [ instead of [[. Because Day is a list, subsetting with [ will return a list, not a numeric vector. [[, however, returns an object of the class of the item contained in the list:

> Day <- Transaction(1, 2)["b"]
> class(Day)
[1] "list"
> Day + 1
Error in Day + 1 : non-numeric argument to binary operator

> Day2 <- Transaction(1, 2)[["b"]]
> class(Day2)
[1] "numeric"
> Day2 + 1
[1] 3

Transaction, as you've defined it, returns a list of two vectors. Above, Day is a list contain one vector. Day2, however, is simply a vector.

Because it's been a several years since this question was first asked, the other answers are outdated or incomplete.

Here's the code for a modern implementation using jQuery:

$( 'div#1' ).on( 'click', function( event ) {
    if ( event.ctrlKey ) {
        //is ctrl + click
    } else {
        //normal click
    }
} );

As for detecting right-clicks, this was correctly provided by another user but I'll list it here just to have everything in one place.

$( 'div#1' ).on( 'contextmenu', function( event ) {
    // right-click handler
} ) ;

Chrome doesn't render the fonts like Firefox or any other browser does. This is generally a problem in Chrome running on Windows only. If you want to make the fonts smooth, use the -webkit-font-smoothing property on yer h4 tags like this.

h4 {
    -webkit-font-smoothing: antialiased;
}

You can also use subpixel-antialiased, this will give you different type of smoothing (making the text a little blurry/shadowed). However, you will need a nightly version to see the effects. You can learn more about font smoothing here.

If you have a branch different than master, one easy way is to check out that branch, then check out master. Voila, you are back at the tip of master. There's probably smarter ways...

Variables:

static variables exist for the "lifetime" of the translation unit that it's defined in, and:

• If it's in a namespace scope (i.e. outside of functions and classes), then it can't be accessed from any other translation unit. This is known as "internal linkage" or "static storage duration". (Don't do this in headers except for constexpr. Anything else, and you end up with a separate variable in each translation unit, which is crazy confusing)
• If it's a variable in a function, it can't be accessed from outside of the function, just like any other local variable. (this is the local they mentioned)
• class members have no restricted scope due to static, but can be addressed from the class as well as an instance (like std::string::npos). [Note: you can declare static members in a class, but they should usually still be defined in a translation unit (cpp file), and as such, there's only one per class]

locations as code:

static std::string namespaceScope = "Hello";
void foo() {
    static std::string functionScope= "World";
}
struct A {
   static std::string classScope = "!";
};

Before any function in a translation unit is executed (possibly after main began execution), the variables with static storage duration (namespace scope) in that translation unit will be "constant initialized" (to constexpr where possible, or zero otherwise), and then non-locals are "dynamically initialized" properly in the order they are defined in the translation unit (for things like std::string="HI"; that aren't constexpr). Finally, function-local statics will be initialized the first time execution "reaches" the line where they are declared. All static variables all destroyed in the reverse order of initialization.

The easiest way to get all this right is to make all static variables that are not constexpr initialized into function static locals, which makes sure all of your statics/globals are initialized properly when you try to use them no matter what, thus preventing the static initialization order fiasco.

T& get_global() {
    static T global = initial_value();
    return global;
}

Be careful, because when the spec says namespace-scope variables have "static storage duration" by default, they mean the "lifetime of the translation unit" bit, but that does not mean it can't be accessed outside of the file.

Functions

Significantly more straightforward, static is often used as a class member function, and only very rarely used for a free-standing function.

A static member function differs from a regular member function in that it can be called without an instance of a class, and since it has no instance, it cannot access non-static members of the class. Static variables are useful when you want to have a function for a class that definitely absolutely does not refer to any instance members, or for managing static member variables.

struct A {
    A() {++A_count;}
    A(const A&) {++A_count;}
    A(A&&) {++A_count;}
    ~A() {--A_count;}

    static int get_count() {return A_count;}
private:
    static int A_count;
}

int main() {
    A var;

    int c0 = var.get_count(); //some compilers give a warning, but it's ok.
    int c1 = A::get_count(); //normal way
}

A static free-function means that the function will not be referred to by any other translation unit, and thus the linker can ignore it entirely. This has a small number of purposes:

• Can be used in a cpp file to guarantee that the function is never used from any other file.
• Can be put in a header and every file will have it's own copy of the function. Not useful, since inline does pretty much the same thing.
• Speeds up link time by reducing work
• Can put a function with the same name in each translation unit, and they can all do different things. For instance, you could put a static void log(const char*) {} in each cpp file, and they could each all log in a different way.

function count_x($connect) {  
 $query = "  SELECT * FROM tbl WHERE id = '0' ";  
 $statement = $connect->prepare($query);  $statement->execute();  
 $total_rows = $statement->rowCount();  
 return $total_rows; 
}

If you only need to share data between views/scopes/controllers, the easiest way is to store it in $rootScope. However, if you need a shared function, it is better to define a service to do that.

One more alternative options

var map = new google.maps.Map(document.getElementById('map_canvas'), {
    zoom: 1,
    center: new google.maps.LatLng(35.137879, -82.836914),
    mapTypeId: google.maps.MapTypeId.ROADMAP
});

var myMarker = new google.maps.Marker({
    position: new google.maps.LatLng(47.651968, 9.478485),
    draggable: true
});

google.maps.event.addListener(myMarker, 'dragend', function (evt) {
    document.getElementById('current').innerHTML = '<p>Marker dropped: Current Lat: ' + evt.latLng.lat().toFixed(3) + ' Current Lng: ' + evt.latLng.lng().toFixed(3) + '</p>';
});

google.maps.event.addListener(myMarker, 'dragstart', function (evt) {
    document.getElementById('current').innerHTML = '<p>Currently dragging marker...</p>';
});

map.setCenter(myMarker.position);
myMarker.setMap(map);

and html file

<body>
    <section>
        <div id='map_canvas'></div>
        <div id="current">Nothing yet...</div>
    </section>

I got stuck on the same error, the problem was coming from a syntax error in a MySql statement in my code, in particular my $_session variable was missing a "'. It took hours to figure it out because on the error log the statement was misleading. Hope it helps somebody.

If you have Excel 2010 you can copy your data into another column, than select it and choose Data -> Remove Duplicates. You can then write =COUNTIF($A$1:$A$100,B1) next to it and copy the formula down. This assumes you have your values in range A1:A100 and the de-duplicated values are in column B.

Try this in Java 8:

Optional first = query.getResultList().stream().findFirst();

By the way, in Notepad++ there's built-in plugin that can handle this: TextFX -> TextFX Edit -> Delete Blank Lines (first press CTRL+A to select all).

Try calling label.Invalidate()

You need to call tf.global_variables_initializer() on you session, like

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

Full example is available in this great tutorial https://www.tensorflow.org/get_started/mnist/mechanics

If you just want to know the number, rather than get it in a query then you can use:

SHOW CREATE TABLE tablename;

You should see the auto_increment at the bottom

You need to use a raw string, double your slashes or use forward slashes instead:

r'C:\Users\expoperialed\Desktop\Python'
'C:\\Users\\expoperialed\\Desktop\\Python'
'C:/Users/expoperialed/Desktop/Python'

In regular python strings, the \U character combination signals a extended Unicode codepoint escape.

You can hit any number of other issues, for any of the recognised escape sequences, such as \a or \t or \x, etc.

You can use quotemeta (\Q \E) if your Perl is version 5.16 or later, but if below you can simply avoid using a regular expression at all.

For example, by using the index command:

if (index($text_to_search, $search_string) > -1) {
    print "wee";
}

Cast(20.5500 as Decimal(6,2))

should do it.

Here is my solution:

dependencies: Gmaps.js, jQuery

var Maps = function($) {
   var lost_addresses = [],
       geocode_count  = 0;

   var addMarker = function() { console.log('Marker Added!') };

   return {
     getGecodeFor: function(addresses) {
        var latlng;
        lost_addresses = [];
        for(i=0;i<addresses.length;i++) {
          GMaps.geocode({
            address: addresses[i],
            callback: function(response, status) {
              if(status == google.maps.GeocoderStatus.OK) {
                addMarker();
              } else if(status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
                lost_addresses.push(addresses[i]);
              }

               geocode_count++;
               // notify listeners when the geocode is done
               if(geocode_count == addresses.length) {
                 $.event.trigger({ type: 'done:geocoder' });
               }
            }
          });
        }
     },
     processLostAddresses: function() {
       if(lost_addresses.length > 0) {
         this.getGeocodeFor(lost_addresses);
       }
     }
   };
}(jQuery);

Maps.getGeocodeFor(address);

// listen to done:geocode event and process the lost addresses after 1.5s
$(document).on('done:geocode', function() {
  setTimeout(function() {
    Maps.processLostAddresses();
  }, 1500);
});

String timeFrSSHStr = timeFrSSH.toString();

Extending your code (assuming that the XML you want to send is in xmlString) :

String xmlString = "</xml>";
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpRequest = new HttpPost(this.url);
httpRequest.setHeader("Content-Type", "application/xml");
StringEntity xmlEntity = new StringEntity(xmlString);
httpRequest.setEntity(xmlEntity );
HttpResponse httpresponse = httpclient.execute(httppost);

This post might be old but i am just posting it incase it helps some other person, I would not advise to Create a .htaccess file in your web root and change the index. I feel it is better to follow the steps

1. Go to the conf folder of your apache folder mine is

   C:\Apache24\conf

2. Open the file named

   httpd.conf

3. Go to the section

   <IfModule dir_module>
      DirectoryIndex index.html 
   
    </IfModule>
   

4. Add index.php to it as shown below

    <IfModule dir_module>
     DirectoryIndex index.html index.php
   
   </IfModule>
   

This way, it still picks index.html and index.php as the default index but giving priority to index.html because index.html came before *index.php. By this I mean in you have both index.html and index.php in the same directory, the index.html will be used as the default index except you write **index.php* before index.hml

I hope it helps someone... Happy Coding

To show only running containers use the given command:

docker ps

To show all containers use the given command:

docker ps -a

To show the latest created container (includes all states) use the given command:

docker ps -l

To show n last created containers (includes all states) use the given command:

docker ps -n=-1

To display total file sizes use the given command:

docker ps -s

The content presented above is from docker.com.

In the new version of Docker, commands are updated, and some management commands are added:

docker container ls

It is used to list all the running containers.

docker container ls -a

And then, if you want to clean them all,

docker rm $(docker ps -aq)

It is used to list all the containers created irrespective of its state.

And to stop all the Docker containers (force)

docker rm -f $(docker ps -a -q)  

Here the container is the management command.

if you run in Jenkins, you can use GIT_BRANCH variable as appears here: https://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin

The git plugin sets several environment variables you can use in your scripts:

GIT_COMMIT - SHA of the current

GIT_BRANCH - Name of the branch currently being used, e.g. "master" or "origin/foo"

GIT_PREVIOUS_COMMIT - SHA of the previous built commit from the same branch (the current SHA on first build in branch)

GIT_URL - Repository remote URL

GIT_URL_N - Repository remote URLs when there are more than 1 remotes, e.g. GIT_URL_1, GIT_URL_2

GIT_AUTHOR_EMAIL - Committer/Author Email

GIT_COMMITTER_EMAIL - Committer/Author Email

When you specify the last Directory on the path remove the last .

for example "\server\directory with space\directory with space".

that should do it.

This is a problem with space consumption or choosing the wrong camera. My suggestion in to restart kernel and clear output and run it again. It works then.

I think you can try this gcc -I/usr/include/mysql *.c -L/usr/lib/mysql -lmysqlclient -o *

The nearest equivalents would be icode and bcode as used by scalac, view Miguel Garcia's site on the Scalac optimiser for more information, here: http://magarciaepfl.github.io/scala/

You might also consider Java bytecode itself to be your intermediate representation, given that bytecode is the ultimate output of scalac.

Or perhaps the true intermediate is something that the JIT produces before it finally outputs native instructions?

Ultimately though... There's no single place that you can point at an claim "there's the intermediate!". Scalac works in phases that successively change the abstract syntax tree, every single phase produces a new intermediate. The whole thing is like an onion, and it's very hard to try and pick out one layer as somehow being more significant than any other.

I'm adding this answer because after arriving here (with the same question), none of the answers really describe all the required steps needed to go from nothing to a fully usable remote (bare) repo.

Note: this example uses local paths for the location of the bare repo, but other git protocols (like SSH indicated by the OP) should work just fine.

I've tried to add some notes along the way for those less familiar with git.

1. Initialise the bare repo...

> git init --bare /path/to/bare/repo.git
Initialised empty Git repository in /path/to/bare/repo.git/

This creates a folder (repo.git) and populates it with git files representing a git repo. As it stands, this repo is useless - it has no commits and more importantly, no branches. Although you can clone this repo, you cannot pull from it.

Next, we need to create a working folder. There are a couple of ways of doing this, depending upon whether you have existing files.

2a. Create a new working folder (no existing files) by cloning the empty repo

git clone /path/to/bare/repo.git /path/to/work
Cloning into '/path/to/work'...
warning: You appear to have cloned an empty repository.
done.

This command will only work if /path/to/work does not exist or is an empty folder. Take note of the warning - at this stage, you still don't have anything useful. If you cd /path/to/work and run git status, you'll get something like:

On branch master

Initial commit

nothing to commit (create/copy files and use "git add" to track)

but this is a lie. You are not really on branch master (because git branch returns nothing) and so far, there are no commits.

Next, copy/move/create some files in the working folder, add them to git and create the first commit.

> cd /path/to/work
> echo 123 > afile.txt
> git add .
> git config --local user.name adelphus
> git config --local user.email [email protected]
> git commit -m "added afile"
[master (root-commit) 614ab02] added afile
 1 file changed, 1 insertion(+)
 create mode 100644 afile.txt

The git config commands are only needed if you haven't already told git who you are. Note that if you now run git branch, you'll now see the master branch listed. Now run git status:

On branch master
Your branch is based on 'origin/master', but the upstream is gone.
  (use "git branch --unset-upstream" to fixup)

nothing to commit, working directory clean

This is also misleading - upstream has not "gone", it just hasn't been created yet and git branch --unset-upstream will not help. But that's OK, now that we have our first commit, we can push and master will be created on the bare repo.

> git push origin master
Counting objects: 3, done.
Writing objects: 100% (3/3), 207 bytes | 0 bytes/s, done.
Total 3 (delta 0), reused 0 (delta 0)
To /path/to/bare/repo.git
 * [new branch]      master -> master

At this point, we have a fully functional bare repo which can be cloned elsewhere on a master branch as well as a local working copy which can pull and push.

> git pull
Already up-to-date.
> git push origin master
Everything up-to-date

2b. Create a working folder from existing files If you already have a folder with files in it (so you cannot clone into it), you can initialise a new git repo, add a first commit and then link it to the bare repo afterwards.

> cd /path/to/work_with_stuff
> git init 
Initialised empty Git repository in /path/to/work_with_stuff
> git add .
# add git config stuff if needed
> git commit -m "added stuff"

[master (root-commit) 614ab02] added stuff
 20 files changed, 1431 insertions(+)
 create mode 100644 stuff.txt
...

At this point we have our first commit and a local master branch which we need to turn into a remote-tracked upstream branch.

> git remote add origin /path/to/bare/repo.git
> git push -u origin master
Counting objects: 31, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (31/31), done.
Writing objects: 100% (31/31), 43.23 KiB | 0 bytes/s, done.
Total 31 (delta 11), reused 0 (delta 0)
To /path/to/bare/repo.git
 * [new branch]      master -> master
Branch master set up to track remote branch master from origin.

Note the -u flag on git push to set the (new) tracked upstream branch. Just as before, we now have a fully functional bare repo which can be cloned elsewhere on a master branch as well as a local working copy which can pull and push.

All this may seem obvious to some, but git confuses me at the best of times (it's error and status messages really need some rework) - hopefully, this will help others.

Open the sql file and comment out the line that tries to create the existing database.

Strange it doesn't change, as inline styles are most specific, if style sheet has !important declared, it wont over ride, try this and see

Use Apache Commons Lang:

String a= "\\*\\";
str = StringUtils.replace(xpath, ".", a);

or with standalone JDK:

String a = "\\*\\"; // or: String a = "/*/";
String replacement = Matcher.quoteReplacement(a);
String searchString = Pattern.quote(".");
String str = xpath.replaceAll(searchString, replacement);

Your syntax error is caused by a missing "table" in the query

ALTER TABLE mytable MODIFY mycolumn varchar(255) null;

New answer:

In HTML5 you can add the multiple attribute to select more than 1 file.

<input type="file" name="filefield" multiple="multiple">

Old answer:

You can only select 1 file per <input type="file" />. If you want to send multiple files you will have to use multiple input tags or use Flash or Silverlight.

It means that trackDAO should not be serialized.

LDAP is a standard, AD is Microsoft's (proprietary) implementation (and more). Wikipedia has a good article that delves into the specifics. I found this document with a very detailed evaluation of AD from an LDAP perspective.

The String[] args parameter is an array of Strings passed as parameters when you are running your application through command line in the OS.

So, imagine you have compiled and packaged a myApp.jar Java application. You can run your app by double clicking it in the OS, of course, but you could also run it using command line way, like (in Linux, for example):

user@computer:~$ java -jar myApp.jar

When you call your application passing some parameters, like:

user@computer:~$ java -jar myApp.jar update notify

The java -jar command will pass your Strings update and notify to your public static void main() method.

You can then do something like:

System.out.println(args[0]); //Which will print 'update'
System.out.println(args[1]); //Which will print 'notify'

Alternatively you can use Minio Client aka mc. Its Open Source and compatible with AWS S3. It is available for Linux, Windows, Mac, FreeBSD.

All you have do do is to run mc ls command for listing the contents.

Using Spring context 5.0 I have successfully achieved loading correct property file based on system environment via the following annotation

@PropertySources({
    @PropertySource("classpath:application.properties"),
    @PropertySource("classpath:application-${MYENV:test}.properties")})

Here MYENV value is read from system environment and if system environment is not present then default test environment property file will be loaded, if I give a wrong MYENV value - it will fail to start the application.

Note: for each profile, you want to maintain - you will need to make an application-[profile].property file and although I used Spring context 5.0 & not Spring boot - I believe this will also work on Spring 4.1

You could simply look in the Active Record Rake tasks as that is where I believe they live as in this file. https://github.com/rails/rails/blob/fe1f4b2ad56f010a4e9b93d547d63a15953d9dc2/activerecord/lib/active_record/tasks/database_tasks.rb

What they do is your question right?

That depends on where they come from and this is just and example to show that they vary depending upon the task. Here we have a different file full of tasks.

https://github.com/rails/rails/blob/fe1f4b2ad56f010a4e9b93d547d63a15953d9dc2/activerecord/Rakefile

which has these tasks.

namespace :db do
  task create: ["db:mysql:build", "db:postgresql:build"]
  task drop: ["db:mysql:drop", "db:postgresql:drop"]
end

This may not answer your question but could give you some insight into go ahead and look the source over especially the rake files and tasks. As they do a pretty good job of helping you use rails they don't always document the code that well. We could all help there if we know what it is supposed to do.

Use .children instead:

from bs4 import NavigableString, Comment
print ''.join(unicode(child) for child in hit.children 
    if isinstance(child, NavigableString) and not isinstance(child, Comment))

Yes, this is a bit of a dance.

Output:

>>> for hit in soup.findAll(attrs={'class' : 'MYCLASS'}):
...     print ''.join(unicode(child) for child in hit.children 
...         if isinstance(child, NavigableString) and not isinstance(child, Comment))
... 




      THIS IS MY TEXT

From the Microsoft documentation: Command prompt (Cmd. exe) command-line string limitation

On computers running Microsoft Windows XP or later, the maximum length of the string that you can use at the command prompt is 8191 characters.

This is helpful for testing purposes.

Seq.empty[String].toDF()

The difference is in the subsystem that each executable targets.

• java.exe targets the CONSOLE subsystem.
• javaw.exe targets the WINDOWS subsystem.

To pull data for the last 3 days, not the current date :

date(timestamp) >= curdate() - 3
AND date(timestamp) < curdate()

Example:

SELECT *

FROM user_login
WHERE age > 18
AND date(timestamp) >= curdate() - 3
AND date(timestamp) < curdate()

LIMIT 10

Personally, I like setting the options directly with an assignment statement as it is easy to find via tab completion thanks to iPython. I find it hard to remember what the exact option names are, so this method works for me.

For instance, all I have to remember is that it begins with pd.options

pd.options.<TAB>

Most of the options are available under display

pd.options.display.<TAB>

From here, I usually output what the current value is like this:

pd.options.display.max_rows
60

I then set it to what I want it to be:

pd.options.display.max_rows = 100

Also, you should be aware of the context manager for options, which temporarily sets the options inside of a block of code. Pass in the option name as a string followed by the value you want it to be. You may pass in any number of options in the same line:

with pd.option_context('display.max_rows', 100, 'display.max_columns', 10):
    some pandas stuff

You can also reset an option back to its default value like this:

pd.reset_option('display.max_rows')

And reset all of them back:

pd.reset_option('all')

It is still perfectly good to set options via pd.set_option. I just find using the attributes directly is easier and there is less need for get_option and set_option.

Original: @Rob, TFS has something called "Shelving" that addresses your concern about commiting work-in-progress without it affecting the official build. I realize you see central version control as a hindrance, but with respect to TFS, checking your code into the shelf can be viewed as a strength b/c then the central server has a copy of your work-in-progress in the rare event your local machine crashes or is lost/stolen or you need to switch gears quickly. My point is that TFS should be given proper praise in this area. Also, branching and merging in TFS2010 has been improved from prior versions, and it isn't clear what version you are referring to when you say "... from experience that branching and merging in TFS is not good." Disclaimer: I'm a moderate user of TFS2010.

Edit Dec-5-2011: To the OP, one thing that bothers me about TFS is that it insists on setting all your local files to "read-only" when you're not working on them. If you want to make a change, the flow is that you must "check-out" the file, which just clears the readonly attribute on the file so that TFS knows to keep an eye on it. That's an inconvenient workflow. The way I would prefer it to work is that is just automatically detects if I've made a change and doesn't worry/bother with the file attributes at all. That way, I can modify the file either in Visual Studio, or Notepad, or with whatever tool I please. The version control system should be as transparent as possible in this regard. There is a Windows Explorer Extension (TFS PowerTools) that allows you to work with your files in Windows Explorer, but that doesn't simplify the workflow very much.

You could print out the tensor value in session as follow:

import tensorflow as tf

a = tf.constant([1, 1.5, 2.5], dtype=tf.float32)
b = tf.constant([1, -2, 3], dtype=tf.float32)
c = a * b

with tf.Session() as sess:
    result = c.eval()
   
print(result)

<input type="text" placeholder="specify">

This adds "specify" as tool-tip text inside the input box.

java: Java application executor which is associated with a console to display output/errors

javaw: (Java windowed) application executor not associated with console. So no display of output/errors. It can be used to silently push the output/errors to text files. It is mostly used to launch GUI-based applications.

javaws: (Java web start) to download and run the distributed web applications. Again, no console is associated.

All are part of JRE and use the same JVM.

Regular Expressions are compiled before being used when using the second version. If you are going to executing it many times it is definatly better to compile it first. If not compiling every time you match for one off's is fine.

I used an inner enum in an interface describing a strategy to keep instance control (each strategy is a Singleton) from there.

public interface VectorizeStrategy {

    /**
     * Keep instance control from here.
     * 
     * Concrete classes constructors should be package private.
     */
    enum ConcreteStrategy implements VectorizeStrategy {
        DEFAULT (new VectorizeImpl());

        private final VectorizeStrategy INSTANCE;

        ConcreteStrategy(VectorizeStrategy concreteStrategy) {
            INSTANCE = concreteStrategy;
        }

        @Override
        public VectorImageGridIntersections processImage(MarvinImage img) {
            return INSTANCE.processImage(img);
        }
    }

    /**
     * Should perform edge Detection in order to have lines, that can be vectorized.
     * 
     * @param img An Image suitable for edge detection.
     * 
     * @return the VectorImageGridIntersections representing img's vectors 
     * intersections with the grids.
     */
    VectorImageGridIntersections processImage(MarvinImage img);
}

The fact that the enum implements the strategy is convenient to allow the enum class to act as proxy for its enclosed Instance. which also implements the interface.

it's a sort of strategyEnumProxy :P the clent code looks like this:

VectorizeStrategy.ConcreteStrategy.DEFAULT.processImage(img);

If it didn't implement the interface it'd had been:

VectorizeStrategy.ConcreteStrategy.DEFAULT.getInstance().processImage(img);

Below python program should work to access hive tables from python:

else:
   print "error"

According to this post, it's much better now:

fixed positioning alone should have fixed that problem but another good workaround to avoid this issue is to place your modal divs or elements at the bottom of the page not within your sites layout. Most modal plugins give their modal positioning absolute to allow the user keep main page scrolling.

<html>
        <body>
        <!-- Put all your page layouts and elements


        <!-- Let the last element be the modal elemment  -->
        <div id="myModals">
        ...
        </div>

        </body>

I had a similar issue with overflowing images in a flex wrapper.

Adding either flex-basis: 100%; or flex: 1; to the overflowing child fixed worked for me.

Select into for large datasets may be good only for a single user using one single connection to the database doing a bulk operation task. I do not recommend to use

SELECT * INTO table

as this creates one big transaction and creates schema lock to create the object, preventing other users to create object or access system objects until the SELECT INTO operation completes.

As proof of concept open 2 sessions, in first session try to use

select into temp table from a huge table 

and in the second section try to

create a temp table 

and check the locks, blocking and the duration of second session to create a temp table object. My recommendation it is always a good practice to create and Insert statement and if needed for minimal logging use trace flag 610.

Smoke testing

Smoke testing came from the hardware environment where testing should be done to check whether the development of a new piece of hardware causes no fire and smoke for the first time.

In the software environment, smoke testing is done to verify whether we can consider for further testing the functionality which is newly built.

Sanity testing

A subset of regression test cases are executed after receiving a functionality or code with small or minor changes in the functionality or code, to check whether it resolved the issues or software bugs and no other software bug is introduced by the new changes.

Difference between smoke testing and sanity testing

Smoke testing

• Smoke testing is used to test all areas of the application without going into too deep.

• A smoke test always use an automated test or a written set of tests. It is always scripted.

• Smoke testing is designed to include every part of the application in a not thorough or detailed way.

• Smoke testing always ensures whether the most crucial functions of a program are working, but not bothering with finer details.

Sanity testing

• Sanity testing is a narrow test that focuses on one or a few areas of functionality, but not thoroughly or in-depth.

• A sanity test is usually unscripted.

• Sanity testing is used to ensure that after a minor change a small part of the application is still working.

• Sanity testing is a cursory testing, which is performed to prove that the application is functioning according to the specifications. This level of testing is a subset of regression testing.

Hope these points help you to understand the difference between smoke testing and sanity testing.

If you're like me running in a restricted environment without administrative privileges, that means your only way to get node up and running is to grab the executable (node.exe) without using the installer. You also cannot change the path variable which makes it that much more challenging.

Here's what I did (for Windows)

1. Throw node.exe into its own folder (Downloaded the node.exe stand-alone )
2. Grab an NPM release zip off of github: https://github.com/npm/npm/releases
3. Create a folder named: node_modules in the node.exe folder
4. Extract the NPM zip into the node_modules folder
5. Make sure the top most folder is named npm (remove any of the versioning on the npm folder name ie: npm-2.12.1 --> npm)
6. Copy npm.cmd out of the npm/bin folder into the top most folder with node.exe
7. Open a command prompt to the node.exe directory (shift right-click "Open command window here")
8. Now you will be able to run your npm installers via: npm install -g express

Running the installers through npm will now auto install packages where they need to be located (node_modules and the root)

Don't forget you will not be able to set the path variable if you do not have proper permissions. So your best route is to open a command prompt in the node.exe directory (shift right-click "Open command window here")

You can use the "ORDER BY DESC" option, then put it back in the original order:

(SELECT * FROM tablename ORDER BY id DESC LIMIT 10) ORDER BY id;

JSfiddle

function deleteEmpty(obj){
        for(var k in obj)
         if(k == "children"){
             if(obj[k]){
                     deleteEmpty(obj[k]);
             }else{
                   delete obj.children;
              } 
         }
    }

for(var i=0; i< a.children.length; i++){
 deleteEmpty(a.children[i])
}

If you only want to return a blank when B2 is blank you can use an additional IF function for that scenario specifically, i.e.

=IF(B2="","",VLOOKUP(B2,Index!A1:B12,2,FALSE))

or to return a blank with any error from the VLOOKUP (e.g. including if B2 is populated but that value isn't found by the VLOOKUP) you can use IFERROR function if you have Excel 2007 or later, i.e.

=IFERROR(VLOOKUP(B2,Index!A1:B12,2,FALSE),"")

in earlier versions you need to repeat the VLOOKUP, e.g.

=IF(ISNA(VLOOKUP(B2,Index!A1:B12,2,FALSE)),"",VLOOKUP(B2,Index!A1:B12,2,FALSE))

Prompted by this question, may I present another alternative which might be a bit nicer to use and will look the same for both methods and functions:

@static_var2('seed',0)
def funccounter(statics, add=1):
    statics.seed += add
    return statics.seed

print funccounter()       #1
print funccounter(add=2)  #3
print funccounter()       #4

class ACircle(object):
    @static_var2('seed',0)
    def counter(statics, self, add=1):
        statics.seed += add
        return statics.seed

c = ACircle()
print c.counter()      #1
print c.counter(add=2) #3
print c.counter()      #4
d = ACircle()
print d.counter()      #5
print d.counter(add=2) #7
print d.counter()      #8    

If you like the usage, here's the implementation:

class StaticMan(object):
    def __init__(self):
        self.__dict__['_d'] = {}

    def __getattr__(self, name):
        return self.__dict__['_d'][name]
    def __getitem__(self, name):
        return self.__dict__['_d'][name]
    def __setattr__(self, name, val):
        self.__dict__['_d'][name] = val
    def __setitem__(self, name, val):
        self.__dict__['_d'][name] = val

def static_var2(name, val):
    def decorator(original):
        if not hasattr(original, ':staticman'):    
            def wrapped(*args, **kwargs):
                return original(getattr(wrapped, ':staticman'), *args, **kwargs)
            setattr(wrapped, ':staticman', StaticMan())
            f = wrapped
        else:
            f = original #already wrapped

        getattr(f, ':staticman')[name] = val
        return f
    return decorator

3. Add a new .aspx page to the project and register the Report Viewer control assembly for use within the page.

   <%@ Register assembly="Microsoft.ReportViewer.WebForms, Version=15.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" namespace="Microsoft.Reporting.WebForms" tagprefix="rsweb" %>
   

4. Add a ScriptManagerControl to the page.

5. Add the Report Viewer control to the page. The snippet below can be updated to reference a report hosted on a remote report server.

    <rsweb:ReportViewer ID="ReportViewer1" runat="server" ProcessingMode="Remote">
    <ServerReport ReportPath="" ReportServerUrl="" /></rsweb:ReportViewer>
   

The final page should look like the following.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="Sample" %>

<%@ Register assembly="Microsoft.ReportViewer.WebForms, Version=15.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" namespace="Microsoft.Reporting.WebForms" tagprefix="rsweb" %>

This works for me to find queries on any database in the instance. I'm sysadmin on the instance (check your privileges):

SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC

This is the same answer that Aaron Bertrand provided but it wasn't placed in an answer.

The rest of answers are pretty good, but just wanted to add some extra information in case someone comes here looking for a solution to replace/update a multiline echo.

So I would like to share an example with you all. The following script was tried on a CentOS system and uses "timedatectl" command which basically prints some detailed time information of your system.

I decided to use that command as its output contains multiple lines and works perfectly for the example below:

#!/bin/bash
while true; do
  COMMAND=$(timedatectl) #Save command result in a var.
  echo "$COMMAND" #Print command result, including new lines.

  sleep 3 #Keep above's output on screen during 3 seconds before clearing it

  #Following code clears previously printed lines
  LINES=$(echo "$COMMAND" | wc -l) #Calculate number of lines for the output previously printed
  for (( i=1; i <= $(($LINES)); i++ ));do #For each line printed as a result of "timedatectl"
    tput cuu1 #Move cursor up by one line
    tput el #Clear the line
  done

done

The above will print the result of "timedatectl" forever and will replace the previous echo with updated results.

I have to mention that this code is only an example, but maybe not the best solution for you depending on your needs. A similar command that would do almost the same (at least visually) is "watch -n 3 timedatectl".

But that's a different story. :)

Hope that helps!

I created this test case: http://jsfiddle.net/ccQnK/1/ , I used the Javascript replace function with regular expressions to get the results that you want.

$(document).ready(function() {
    var myContent = '<div id="test">Hello <span>world!</span></div>';
    alert(myContent.replace(/(<([^>]+)>)/ig,""));
});

Solved in may of 2018 with the new Android Studio 3.1. Delete the .gradle, .idea and build directories inside your app folder. Then try to run it again and you won't see the error.

I managed to remove the errors by disabling the validations:

{
    "javascript.validate.enable": false,
    "html.validate.styles": false,
    "html.validate.scripts": false,
    "css.validate": false,
    "scss.validate": false
}

Obs: My project is a PWA using StyledComponents, React, Flow, Eslint and Prettier.

Here's how i am calling my modal

<a data-toggle="modal" data-id="190" data-target="#modal-popup">Open</a>

Here's how i am obtaining value in the modal

$('#modal-popup').on('show.bs.modal', function(e) {
    console.log($(e.relatedTarget).data('id')); // 190 will be printed
});

if you want to use "System.Data.Objects.EntityFunctions"

use "System.Data.Entity.DbFunctions" in EF 6.1+

A solution without the Desktop environment is BrowserLauncher2. This solution is more general as on Linux, Desktop is not always available.

The lenghty answer is posted at https://stackoverflow.com/a/21676290/873282

There must be a user in the AllowUsers section, in the config file /etc/ssh/ssh_config, in the remote machine. You might have to restart sshd after editing the config file.

And then you can copy for example the file "test.txt" from a remote host to the local host

scp [email protected]:test.txt /local/dir

@cool_cs you can user ~ symbol ~/Users/djorge/Desktop if it's your home dir.

In UNIX, absolute paths must start with '/'.

I tried out most options mentioned previously but found this small and intuitive package to be the best: pympler

It's quite straight forward to trace objects that were not garbage-collected, check this small example:

install package via pip install pympler

from pympler.tracker import SummaryTracker
tracker = SummaryTracker()

# ... some code you want to investigate ...

tracker.print_diff()

The output shows you all the objects that have been added, plus the memory they consumed.

Sample output:

                                 types |   # objects |   total size
====================================== | =========== | ============
                                  list |        1095 |    160.78 KB
                                   str |        1093 |     66.33 KB
                                   int |         120 |      2.81 KB
                                  dict |           3 |       840 B
      frame (codename: create_summary) |           1 |       560 B
          frame (codename: print_diff) |           1 |       480 B

This package provides a number of more features. Check pympler's documentation, in particular the section Identifying memory leaks.

"Fork" in this context means "Make a copy of their code so that I can add my own modifications". There's not much else to say. Every clone is essentially a fork, and it's up to the original to decide whether to pull the changes from the fork.

If you want to print/write double value at console then use System.out.printf() or System.out.format() methods.

System.out.printf("\n$%10.2f",shippingCost);
System.out.printf("%n$%.2f",shippingCost);

Set to today:

$('#date_pretty').datepicker('setDate', '+0');

Set to yesterday:

$('#date_pretty').datepicker('setDate', '-1');

And so on with any number of days before or after today's date.

How to show uncommitted changes in Git

The command you are looking for is git diff.

git diff - Show changes between commits, commit and working tree, etc

Here are some of the options it expose which you can use

git diff (no parameters)
Print out differences between your working directory and the index.

git diff --cached:
Print out differences between the index and HEAD (current commit).

git diff HEAD:
Print out differences between your working directory and the HEAD.

git diff --name-only
Show only names of changed files.

git diff --name-status
Show only names and status of changed files.

git diff --color-words
Word by word diff instead of line by line.

Here is a sample of the output for git diff --color-words:

len(repr(float(x)/3))

However I must say that this isn't as reliable as you think.

Floats are entered/displayed as decimal numbers, but your computer (in fact, your standard C library) stores them as binary. You get some side effects from this transition:

>>> print len(repr(0.1))
19
>>> print repr(0.1)
0.10000000000000001

The explanation on why this happens is in this chapter of the python tutorial.

A solution would be to use a type that specifically tracks decimal numbers, like python's decimal.Decimal:

>>> print len(str(decimal.Decimal('0.1')))
3

Maybe I didn't understand your problem right, because of the simplicity of your example. To my understanding, you have a series of instructions stored in character vectors, and those instructions are very close to being properly formatted, except that you'd like to cast the right member to numeric.

If my understanding is right, I would like to propose a slightly different approach, that does not rely on splitting your original string, but directly evaluates your instruction (with a little improvement).

original_string <- "variable_name=\"10\"" # Your original instruction, but with an actual numeric on the right, stored as character.
library(magrittr) # Or library(tidyverse), but it seems a bit overkilled if the point is just to import pipe-stream operator
eval(parse(text=paste(eval(original_string), "%>% as.numeric")))
print(variable_name)
#[1] 10

Basically, what we are doing is that we 'improve' your instruction variable_name="10" so that it becomes variable_name="10" %>% as.numeric, which is an equivalent of variable_name=as.numeric("10") with magrittr pipe-stream syntax. Then we evaluate this expression within current environment.

Hope that helps someone who'd wander around here 8 years later ;-)

LGrind does this. It's a mature LaTeX package that's been around since adam was a cowboy and has support for many programming languages.

The minimum required:

import java.util.Properties;

import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class MessageSender {

    public static void sendHardCoded() throws AddressException, MessagingException {
        String to = "[email protected]";
        final String from = "[email protected]";

        Properties properties = new Properties();
        properties.put("mail.smtp.starttls.enable", "true");
        properties.put("mail.smtp.auth", "true");
        properties.put("mail.smtp.host", "smtp.gmail.com");
        properties.put("mail.smtp.port", "587");

        Session session = Session.getInstance(properties,
                new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(from, "BeNice");
                    }
                });

        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
        message.setSubject("Hello");
        message.setText("What's up?");

        Transport.send(message);
    }

}

Just use DROP TABLE IF EXISTS:

DROP TABLE IF EXISTS `foo`;
CREATE TABLE `foo` ( ... );

Try searching the MySQL documentation first if you have any other problems.

ul { 
    display: block;

    margin-top: 1em;

    margin-left: 0;
    margin-right: 0;
    padding-left: 40px;
}

I agree with most people that using ordinal is probably a bad idea. I usually solve this problem by giving the enum a private constructor that can take for example a DB value then create a static fromDbValue function similar to the one in Jan's answer.

public enum ReportTypeEnum {
    R1(1),
    R2(2),
    R3(3),
    R4(4),
    R5(5),
    R6(6),
    R7(7),
    R8(8);

    private static Logger log = LoggerFactory.getLogger(ReportEnumType.class);  
    private static Map<Integer, ReportTypeEnum> lookup;
    private Integer dbValue;

    private ReportTypeEnum(Integer dbValue) {
        this.dbValue = dbValue;
    }


    static {
        try {
            ReportTypeEnum[] vals = ReportTypeEnum.values();
            lookup = new HashMap<Integer, ReportTypeEnum>(vals.length);

            for (ReportTypeEnum  rpt: vals)
                lookup.put(rpt.getDbValue(), rpt);
         }
         catch (Exception e) {
             // Careful, if any exception is thrown out of a static block, the class
             // won't be initialized
             log.error("Unexpected exception initializing " + ReportTypeEnum.class, e);
         }
    }

    public static ReportTypeEnum fromDbValue(Integer dbValue) {
        return lookup.get(dbValue);
    }

    public Integer getDbValue() {
        return this.dbValue;
    }

}

Now you can change the order without changing the lookup and vice versa.

You should use datetime.datetime.strptime:

import datetime

dt = datetime.datetime.strptime(string_date, fmt)

fmt will need to be the appropriate format for your string. You'll find the reference on how to build your format here.

An easy way to have access to the token, is to put the token in the LocalStorage or the AsyncStorage with React Native.

Below an example with a React Native project

authReducer.js

import { AsyncStorage } from 'react-native';
...
const auth = (state = initialState, action) => {
  switch (action.type) {
    case SUCCESS_LOGIN:
      AsyncStorage.setItem('token', action.payload.token);
      return {
        ...state,
        ...action.payload,
      };
    case REQUEST_LOGOUT:
      AsyncStorage.removeItem('token');
      return {};
    default:
      return state;
  }
};
...

and api.js

import axios from 'axios';
import { AsyncStorage } from 'react-native';

const defaultHeaders = {
  'Content-Type': 'application/json',
};

const config = {
  ...
};

const request = axios.create(config);

const protectedRequest = options => {
  return AsyncStorage.getItem('token').then(token => {
    if (token) {
      return request({
        headers: {
          ...defaultHeaders,
          Authorization: `Bearer ${token}`,
        },
        ...options,
      });
    }
    return new Error('NO_TOKEN_SET');
  });
};

export { request, protectedRequest };

For web you can use Window.localStorage instead of AsyncStorage

ConcurrentLinkedQueue means no locks are taken (i.e. no synchronized(this) or Lock.lock calls). It will use a CAS - Compare and Swap operation during modifications to see if the head/tail node is still the same as when it started. If so, the operation succeeds. If the head/tail node is different, it will spin around and try again.

LinkedBlockingQueue will take a lock before any modification. So your offer calls would block until they get the lock. You can use the offer overload that takes a TimeUnit to say you are only willing to wait X amount of time before abandoning the add (usually good for message type queues where the message is stale after X number of milliseconds).

Fairness means that the Lock implementation will keep the threads ordered. Meaning if Thread A enters and then Thread B enters, Thread A will get the lock first. With no fairness, it is undefined really what happens. It will most likely be the next thread that gets scheduled.

As for which one to use, it depends. I tend to use ConcurrentLinkedQueue because the time it takes my producers to get work to put onto the queue is diverse. I don't have a lot of producers producing at the exact same moment. But the consumer side is more complicated because poll won't go into a nice sleep state. You have to handle that yourself.

The value of a field can not be null, it's always a string value.

The code will check if the string value is the string "NULL". You want to check if it's an empty string instead:

if ($('#person_data[document_type]').val() != ''){}

or:

if ($('#person_data[document_type]').val().length != 0){}

If you want to check if the element exist at all, you should do that before calling val:

var $d = $('#person_data[document_type]');
if ($d.length != 0) {
  if ($d.val().length != 0 ) {...}
}

How about this? (jsFiddle link)

The given answer will throw an error if used in Microsoft Excel 14.0 Object Library. Object does not contain a definition for get_range. Instead use

int countRows = xlWorkSheetData.UsedRange.Rows.Count;
int countColumns = xlWorkSheetData.UsedRange.Columns.Count;
object[,] data = xlWorkSheetData.Range[xlWorkSheetData.Cells[1, 1], xlWorkSheetData.Cells[countRows, countColumns]].Cells.Value2;

 public interface IService { 

  String BASE_URL = "https://api.demo.com/";

  @GET("Login") //i.e https://api.demo.com/Search? 
  Call<Products> getUserDetails(@Query("email") String emailID, @Query("password") String password)

} 

It will be called this way. Considering you did the rest of the code already.

Call<Results> call = service.getUserDetails("[email protected]", "Password@123");

For example when a query is returned, it will look like this.

https://api.demo.com/[email protected]&password=Password@123

In Kotlin will be :

activity?.applicationContext?.let {
         it//<- you context
        }

You will be much happier using a dictionary instead:

my_data = {}
foo = "hello"
my_data[foo] = "goodbye"
assert my_data["hello"] == "goodbye"

You can use the -quit option of find:

find <dir> -maxdepth 1 -type d -name '*foo*' -print -quit

Firstly your approach is inefficient because the appending to the list on a row by basis will be slow as it has to periodically grow the list when there is insufficient space for the new entry, list comprehensions are better in this respect as the size is determined up front and allocated once.

However, I think fundamentally your approach is a little wasteful as you have a dataframe already so why create a new one for each of these users?

I would sort the dataframe by column 'name', set the index to be this and if required not drop the column.

Then generate a list of all the unique entries and then you can perform a lookup using these entries and crucially if you only querying the data, use the selection criteria to return a view on the dataframe without incurring a costly data copy.

Use pandas.DataFrame.sort_values and pandas.DataFrame.set_index:

# sort the dataframe
df.sort_values(by='name', axis=1, inplace=True)

# set the index to be this and don't drop
df.set_index(keys=['name'], drop=False,inplace=True)

# get a list of names
names=df['name'].unique().tolist()

# now we can perform a lookup on a 'view' of the dataframe
joe = df.loc[df.name=='joe']

# now you can query all 'joes'

find supports -delete operation, so:

find /base/dir/* -ctime +10 -delete;

I think there's a catch that the files need to be 10+ days older too. Haven't tried, someone may confirm in comments.

The most voted solution here is missing -maxdepth 0 so it will call rm -rf for every subdirectory, after deleting it. That doesn't make sense, so I suggest:

find /base/dir/* -maxdepth 0  -type d -ctime +10 -exec rm -rf {} \;

The -delete solution above doesn't use -maxdepth 0 because find would complain the dir is not empty. Instead, it implies -depth and deletes from the bottom up.

Just add margin: 0 auto; to the inside div.

You need to make both your method - printMenu() and getUserChoice() static, as you are directly invoking them from your static main method, without creating an instance of the class, those methods are defined in. And you cannot invoke a non-static method without any reference to an instance of the class they are defined in.

Alternatively you can change the method invocation part to:

BookStoreApp2 bookStoreApp = new BookStoreApp2();
bookStoreApp.printMenu();
bookStoreApp.getUserChoice();

You might find it useful to extend the Storage object with these handy methods:

Storage.prototype.setObject = function(key, value) {
    this.setItem(key, JSON.stringify(value));
}

Storage.prototype.getObject = function(key) {
    return JSON.parse(this.getItem(key));
}

This way you get the functionality that you really wanted even though underneath the API only supports strings.

Here is how I approached it. My div height is 650px. I decided that if the scroll height is within 150px of the bottom then auto scroll it. Else, leave it for the user.

if (container_block.scrollHeight - container_block.scrollTop < 800) {
                    container_block.scrollTo(0, container_block.scrollHeight);
}

From this: (source)

function bytesToSize(bytes) {
   var sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB'];
   if (bytes == 0) return '0 Byte';
   var i = parseInt(Math.floor(Math.log(bytes) / Math.log(1024)));
   return Math.round(bytes / Math.pow(1024, i), 2) + ' ' + sizes[i];
}

Note : This is original code, Please use fixed version below. Aliceljm does not active her copied code anymore

Now, Fixed version unminified, and ES6'ed: (by community)

function formatBytes(bytes, decimals = 2) {
    if (bytes === 0) return '0 Bytes';

    const k = 1024;
    const dm = decimals < 0 ? 0 : decimals;
    const sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'];

    const i = Math.floor(Math.log(bytes) / Math.log(k));

    return parseFloat((bytes / Math.pow(k, i)).toFixed(dm)) + ' ' + sizes[i];
}

Now, Fixed version : (by Stackoverflow's community, + Minified by JSCompress)

function formatBytes(a,b=2){if(0===a)return"0 Bytes";const c=0>b?0:b,d=Math.floor(Math.log(a)/Math.log(1024));return parseFloat((a/Math.pow(1024,d)).toFixed(c))+" "+["Bytes","KB","MB","GB","TB","PB","EB","ZB","YB"][d]}

Usage :

// formatBytes(bytes,decimals)

formatBytes(1024);       // 1 KB
formatBytes('1024');     // 1 KB
formatBytes(1234);       // 1.21 KB

In my case updating GIT helps - I had version 2.23 and with installing version 2.26.2.windows.1 problem disapears.

So if you are sure your SSH key is valid then (see @VonC answer):

1. update GIT
2. update composer
3. run composer clearcache

And it should be ok.

1) You cannot overload the method (Why doesn't ruby support method overloading?) so why not write a new method altogether?

2) I solved a similar problem using the splat operator * for an array of zero or more length. Then, if I want to pass a parameter(s) I can, it is interpreted as an array, but if I want to call the method without any parameter then I don't have to pass anything. See Ruby Programming Language pages 186/187

Creates the directory named by this abstract pathname, including any necessary but nonexistent parent directories. Note that if this operation fails it may have succeeded in creating some of the necessary parent directories.

javadocs for mkdir():

Creates the directory named by this abstract pathname.

Example:

File  f = new File("non_existing_dir/someDir");
System.out.println(f.mkdir());
System.out.println(f.mkdirs());

will yield false for the first [and no dir will be created], and true for the second, and you will have created non_existing_dir/someDir

@ts-expect-error

TS 3.9 introduces a new magic comment. @ts-expect-error will:

• have same functionality as @ts-ignore
• trigger an error, if actually no compiler error has been suppressed (= indicates useless flag)

if (false) {
  // @ts-expect-error: Let's ignore a single compiler error like this unreachable code 
  console.log("hello"); // compiles
}

// If @ts-expect-error didn't suppress anything at all, we now get a nice warning 
let flag = true;
// ...
if (flag) {
  // @ts-expect-error
  // ^~~~~~~~~~~~~~~^ error: "Unused '@ts-expect-error' directive.(2578)"
  console.log("hello"); 
}

Alternatives

@ts-ignore and @ts-expect-error can be used for all sorts of compiler errors. For type issues (like in OP), I recommend one of the following alternatives due to narrower error suppression scope:

? Use any type

// type assertion for single expression
delete ($ as any).summernote.options.keyMap.pc.TAB;

// new variable assignment for multiple usages
const $$: any = $
delete $$.summernote.options.keyMap.pc.TAB;
delete $$.summernote.options.keyMap.mac.TAB;

? Augment JQueryStatic interface

// ./global.d.ts
interface JQueryStatic {
  summernote: any;
}

// ./main.ts
delete $.summernote.options.keyMap.pc.TAB; // works

In other cases, shorthand module declarations or module augmentations for modules with no/extendable types are handy utilities. A viable strategy is also to keep not migrated code in .js and use --allowJs with checkJs: false.

If you want to use 32-bit references, your heap is limited to 32 GB.

However, if you are willing to use 64-bit references, the size is likely to be limited by your OS, just as it is with 32-bit JVM. e.g. on Windows 32-bit this is 1.2 to 1.5 GB.

Note: you will want your JVM heap to fit into main memory, ideally inside one NUMA region. That's about 1 TB on the bigger machines. If your JVM spans NUMA regions the memory access and the GC in particular will take much longer. If your JVM heap start swapping it might take hours to GC, or even make your machine unusable as it thrashes the swap drive.

Note: You can access large direct memory and memory mapped sizes even if you use 32-bit references in your heap. i.e. use well above 32 GB.

Compressed oops in the Hotspot JVM

Compressed oops represent managed pointers (in many but not all places in the JVM) as 32-bit values which must be scaled by a factor of 8 and added to a 64-bit base address to find the object they refer to. This allows applications to address up to four billion objects (not bytes), or a heap size of up to about 32Gb. At the same time, data structure compactness is competitive with ILP32 mode.

why dont you use export, then click 'Custom - display all possible options' radio button, then choose your database, then go to Output and choose 'View output as text' just scroll down and Go. Voila!

On Unix systems, for several projects, I added these lines into the CMakeLists.txt and it was compiling successfully because base (/usr/include) and local includes (/usr/local/include) go into separated directories:

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -I/usr/local/include -L/usr/local/lib")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/usr/local/include")
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -L/usr/local/lib")

It appends the correct directory, including paths for the C and C++ compiler flags and the correct directory path for the linker flags.

Note: C++ compiler (c++) doesn't support -L, so we have to use CMAKE_EXE_LINKER_FLAGS

1.> Change File format to .CSV (semicolon delimited)

To achieve the desired result we need to temporary change the delimiter setting in the Excel Options:

Move to File -> Options -> Advanced -> Editing Section

Uncheck the “Use system separators” setting and put a comma in the “Decimal Separator” field.

Now save the file in the .CSV format and it will be saved in the semicolon delimited format.

Actually you can capture Query strings in MVC in two ways.....

public ActionResult CrazyMVC(string knownQuerystring)
{

  // This is the known query string captured by the Controller Action Method parameter above
  string myKnownQuerystring = knownQuerystring;

  // This is what I call the mysterious "unknown" query string
  // It is not known because the Controller isn't capturing it
  string myUnknownQuerystring = Request.QueryString["unknownQuerystring"];

  return Content(myKnownQuerystring + " - " + myUnknownQuerystring);

}

This would capture both query strings...for example:

/CrazyMVC?knownQuerystring=123&unknownQuerystring=456

Output: 123 - 456

Don't ask me why they designed it that way. Would make more sense if they threw out the whole Controller action system for individual query strings and just returned a captured dynamic list of all strings/encoded file objects for the URL by url-form-encoding so you can easily access them all in one call. Maybe someone here can demonstrate that if its possible?

Makes no sense to me how Controllers capture query strings, but it does mean you have more flexibility to capture query strings than they teach you out of the box. So pick your poison....both work fine.

always use with statement like ;WITH then you'll never get this error. The WITH command required a ; between it and any previous command, by always using ;WITH you'll never have to remember to do this.

see WITH common_table_expression (Transact-SQL), from the section Guidelines for Creating and Using Common Table Expressions:

When a CTE is used in a statement that is part of a batch, the statement before it must be followed by a semicolon.

Its boils down to this: math.h is from C and was created over 10 years ago. In math.h, due to its primitive nature, the abs() function is "essentially" just for integer types and if you wanted to get the absolute value of a double, you had to use fabs(). When C++ was created it took math.h and made it cmath. cmath is essentially math.h but improved for C++. It improved things like having to distinguish between fabs() and abs, and just made abs() for both doubles and integer types. In summary either: Use math.h and use abs() for integers, fabs() for doubles or use cmath and just have abs for everything (easier and recommended)

Hope this helps anyone who is having the same problem!

If you are using Maven and packaging your Java classes as JAR, then make sure that JAR is up to date. Still assuming that JAR is in your classpath of course.

import math

dist = math.hypot(math.hypot(xa-xb, ya-yb), za-zb)

This is the steps that worked for me (For both Mac and Windows):

1. Click on "File"
2. Click on "Invalidate Caches / Restart ..."
3. Choose: "Invalidate and Restart"
4. Wait for 20 minutes

Convert both dates to timestamps then do

pseudocode:

if date_from_user > start_date && date_from_user < end_date
    return true

You could add a context menu entry through the registry:

1. Navigate in your Registry to HKEY_LOCAL_MACHINE/Software/Classes/Folder/Shell and create a key called "Command Prompt" without the quotes.

2. Set the default string to whatever text you want to appear in the right-click menu.

3. Create a new key within your newly created command prompt named "command," and set the default string to

   cmd.exe /k pushd %1
   

You may need to add %SystemRoot%\system32\ before the cmd.exe if the executable can't be found.

1. The changes should take place immediately. Right click a folder and your new menu item should appear.

As answer by Neodan mongoexport is quite useful with -q option for query. It also convert ObjectId to standard format of JSON "$oid". E.g:

mongoexport -d yourdb -c yourcol --jsonArray --pretty -q '{"field": "filter value"}' -o output.json

You can also do like this if you're only interested in extracting the "user_id":

String userId = 
given().
        contentType("application/json").
        body(requestBody).
when().
        post("/admin").
then().
        statusCode(200).
extract().
        path("user_id");

In its simplest form it looks like this:

String userId = get("/person").path("person.userId");

If you want to allow 1 and 1.2:

(?<=^| )\d+(\.\d+)?(?=$| )

If you want to allow 1, 1.2 and .1:

(?<=^| )\d+(\.\d+)?(?=$| )|(?<=^| )\.\d+(?=$| )

If you want to only allow 1.2 (only floats):

(?<=^| )\d+\.\d+(?=$| )

\d allows digits (while \D allows anything but digits).

(?<=^| ) checks that the number is preceded by either a space or the beginning of the string. (?=$| ) makes sure the string is followed by a space or the end of the string. This makes sure the number isn't part of another number or in the middle of words or anything.

Edit: added more options, improved the regexes by adding lookahead- and behinds for making sure the numbers are standalone (i.e. aren't in the middle of words or other numbers.

this is a simple implementation:

lv.setOnScrollListener(new OnScrollListener() {
        private int mLastFirstVisibleItem;

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {

        }

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem,
                int visibleItemCount, int totalItemCount) {

            if(mLastFirstVisibleItem<firstVisibleItem)
            {
                Log.i("SCROLLING DOWN","TRUE");
            }
            if(mLastFirstVisibleItem>firstVisibleItem)
            {
                Log.i("SCROLLING UP","TRUE");
            }
            mLastFirstVisibleItem=firstVisibleItem;

        }
    });

and if you need more precision, you can use this custom ListView class:

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.AbsListView;
import android.widget.ListView;

/**
 * Created by root on 26/05/15.
 */
public class ScrollInterfacedListView extends ListView {


    private OnScrollListener onScrollListener;
    private OnDetectScrollListener onDetectScrollListener;

    public ScrollInterfacedListView(Context context) {
        super(context);
        onCreate(context, null, null);
    }

    public ScrollInterfacedListView(Context context, AttributeSet attrs) {
        super(context, attrs);
        onCreate(context, attrs, null);
    }

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

    @SuppressWarnings("UnusedParameters")
    private void onCreate(Context context, AttributeSet attrs, Integer defStyle) {
        setListeners();
    }

    private void setListeners() {
        super.setOnScrollListener(new OnScrollListener() {

            private int oldTop;
            private int oldFirstVisibleItem;

            @Override
            public void onScrollStateChanged(AbsListView view, int scrollState) {
                if (onScrollListener != null) {
                    onScrollListener.onScrollStateChanged(view, scrollState);
                }
            }

            @Override
            public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                if (onScrollListener != null) {
                    onScrollListener.onScroll(view, firstVisibleItem, visibleItemCount, totalItemCount);
                }

                if (onDetectScrollListener != null) {
                    onDetectedListScroll(view, firstVisibleItem);
                }
            }

            private void onDetectedListScroll(AbsListView absListView, int firstVisibleItem) {
                View view = absListView.getChildAt(0);
                int top = (view == null) ? 0 : view.getTop();

                if (firstVisibleItem == oldFirstVisibleItem) {
                    if (top > oldTop) {
                        onDetectScrollListener.onUpScrolling();
                    } else if (top < oldTop) {
                        onDetectScrollListener.onDownScrolling();
                    }
                } else {
                    if (firstVisibleItem < oldFirstVisibleItem) {
                        onDetectScrollListener.onUpScrolling();
                    } else {
                        onDetectScrollListener.onDownScrolling();
                    }
                }

                oldTop = top;
                oldFirstVisibleItem = firstVisibleItem;
            }
        });
    }

    @Override
    public void setOnScrollListener(OnScrollListener onScrollListener) {
        this.onScrollListener = onScrollListener;
    }

    public void setOnDetectScrollListener(OnDetectScrollListener onDetectScrollListener) {
        this.onDetectScrollListener = onDetectScrollListener;
    }


    public interface OnDetectScrollListener {

        void onUpScrolling();

        void onDownScrolling();
    }

}

an example for use: (don't forget to add it as an Xml Tag in your layout.xml)

scrollInterfacedListView.setOnDetectScrollListener(new ScrollInterfacedListView.OnDetectScrollListener() {
            @Override
            public void onUpScrolling() {
               //Do your thing
            }

            @Override
            public void onDownScrolling() {

             //Do your thing
            }
        });

Here is the thing, there is no way to "temporarily" disable cross-domain XMLHttpRequest, if you can disable it temporarily then it can be disabled permanently. This is a rather common problem in the modern-day of AJAX programming and is most often solved using the technique known as cross-domain scripting.

The idea here being is that if you call out to a cross-domain script it returns JavaScript (JSON) results that are then passed on to a function on your end.

Here is some sample code to illustrate how it may look from a JavaScript code perspective:

  function request_some_data() {
    var s = "http://my.document.url.com/my_data?p1=v1&p2=v2&callback=myfunc";

      try {
        try{
          document.write("<scr"+"ipt type='text/javascript' src='"+s+"'></scr"+"ipt>");
        } 
        catch(e){
          var x = document.createElement("script");
          x.src = s;
          document.getElementsByTagName("head")[0].appendChild(x);
        }
      }
      catch (e) {
        alert(e.message);
      }
   }

You will then define a function in your code that receives the data and in the server you "handle" the callback case, here is the client-side JavaScript:

function myfunc(data) {
  alert(data);
}

And on the server side, here i'm giving a PHP example but this can be done just as easily in Java or what-ever your server-side technology is:

<?php
   if($_GET["callback"]) {
     print($_GET["callback"] . "(");
   }
   /* place your JSON object code/logic here */
   if($_GET["callback"]) {
     print(");");
   }
 ?>

Note that what you are generating on the server side winds up being some JavaScript that gets executed on the client side.

The Uri class is generally your best bet for manipulating Urls.

Bash.

The various UNIX and Linux implementations have various different source level implementations of ksh, some of which are real ksh, some of which are pdksh implementations and some of which are just symlinks to some other shell that has a "ksh" personality. This can lead to weird differences in execution behavior.

At least with bash you can be sure that it's a single code base, and all you need worry about is what (usually minimum) version of bash is installed. Having done a lot of scripting on pretty much every modern (and not-so-modern) UNIX, programming to bash is more reliably consistent in my experience.

There’s a function in Gary Bernhardt’s .vimrc that handles this.

function! RenameFile()
let old_name = expand('%')
let new_name = input('New file name: ', expand('%'), 'file')
if new_name != '' && new_name != old_name
    exec ':saveas ' . new_name
    exec ':silent !rm ' . old_name
    redraw!
endif
endfunction
map <leader>n :call RenameFile()<cr>

i created a custom collection view layout here that supports:

• paging one cell at a time
• paging 2+ cells at a time depending on swipe velocity
• horizontal or vertical directions

it's as easy as:

let layout = PagingCollectionViewLayout()

layout.itemSize = 
layout.minimumLineSpacing = 
layout.scrollDirection = 

you can just add PagingCollectionViewLayout.swift to your project

or

add pod 'PagingCollectionViewLayout' to your podfile

constexpr indicates a value that's constant and known during compilation.
const indicates a value that's only constant; it's not compulsory to know during compilation.

int sz;
constexpr auto arraySize1 = sz;    // error! sz's value unknown at compilation
std::array<int, sz> data1;         // error! same problem

constexpr auto arraySize2 = 10;    // fine, 10 is a compile-time constant
std::array<int, arraySize2> data2; // fine, arraySize2 is constexpr

Note that const doesn’t offer the same guarantee as constexpr, because const objects need not be initialized with values known during compilation.

int sz;
const auto arraySize = sz;       // fine, arraySize is const copy of sz
std::array<int, arraySize> data; // error! arraySize's value unknown at compilation

All constexpr objects are const, but not all const objects are constexpr.

If you want compilers to guarantee that a variable has a value that can be used in contexts requiring compile-time constants, the tool to reach for is constexpr, not const.

this also works:

a=pd.DataFrame({'A':a.groupby('A')['B'].max().index,'B':a.groupby('A')       ['B'].max().values})

If i understand your question right, one way to do is break down the string in chars and then check each char in that string using a loop whether it's a string or a number and then if string save it in a variable and then once the loop is finished, display that to the user

Just to add another set of answers:

• I commit whenever I finish a piece of work. Sometimes it's a tiny bugfix that just changed one line and took me 2 minutes to do; other times it's two weeks worth of sweat. Also, as a rule of thumb, you don't commit anything that breaks the build. Thus if it has taken you a long time to do something, take the latest version before committing, and see if your changes break the build. Of course, if I go a long time without committing, it makes me uneasy because I don't want to loose that work. In TFS I use this nice thing as "shelvesets" for this. In SVN you'll have to work around in another way. Perhaps create your own branch or backup these files manually to another machine.
• Branches are copies of your whole project. The best illustration for their use is perhaps the versioning of products. Imagine that you are working at a large project (say, the Linux kernel). After months of sweat you've finally arrived at version 1.0 that you release to the public. After that you start to work on version 2.0 of you product which is going to be way better. But in the mean time there are also a lot of people out there which are using version 1.0. And these people find bugs that you have to fix. Now, you can't fix the bug in the upcoming 2.0 version and ship that to the clients - it's not ready at all. Instead you have to pull out an old copy of 1.0 source, fix the bug there, and ship that to the people. This is what branches are for. When you released the 1.0 version you made a branch in SVN which made a copy of the source code at that point. This branch was named "1.0". You then continued work on the next version in your main source copy, but the 1.0 copy remained there as it was at the moment of the release. And you can continue fixing bugs there. Tags are just names attached to specific revisions for ease of use. You could say "Revision 2342 of the source code", but it's easier to refer to it as "First stable revision". :)
• I usually put everything in the source control that relates directly to the programming. For example, since I'm making webpages, I also put images and CSS files in source control, not to mention config files etc. Project documentation does not go in there, however that is actually just a matter of preference.

Unless you want to do something more complicated, feeding data from a HTML form into Flask is pretty easy.

• Create a view that accepts a POST request (my_form_post).
• Access the form elements in the dictionary request.form.

templates/my-form.html:

<form method="POST">
    <input name="text">
    <input type="submit">
</form>

from flask import Flask, request, render_template

app = Flask(__name__)

@app.route('/')
def my_form():
    return render_template('my-form.html')

@app.route('/', methods=['POST'])
def my_form_post():
    text = request.form['text']
    processed_text = text.upper()
    return processed_text

This is the Flask documentation about accessing request data.

If you need more complicated forms that need validation then you can take a look at WTForms and how to integrate them with Flask.

Note: unless you have any other restrictions, you don't really need JavaScript at all to send your data (although you can use it).

You'll need to generate the SQL content dynamically:

declare @tablename varchar(50)

set @tablename = 'test'

declare @sql varchar(500)

set @sql = 'select * from ' + @tablename

exec (@sql)

purrr::flatten_*() is also a good option. the flatten_* functions add thin sanity checks and ensure type safety.

myList <- list('A'=1, 'B'=2, 'C'=3)

purrr::flatten_dbl(myList)
## [1] 1 2 3

When you do a cmp a,b, the flags are set as if you had calculated a - b.

Then the jmp-type instructions check those flags to see if the jump should be made.

In other words, the first block of code you have (with my comments added):

cmp al,dl     ; set flags based on the comparison
jg label1     ; then jump based on the flags

would jump to label1 if and only if al was greater than dl.

You're probably better off thinking of it as al > dl but the two choices you have there are mathematically equivalent:

al > dl
al - dl > dl - dl (subtract dl from both sides)
al - dl > 0       (cancel the terms on the right hand side)

You need to be careful when using jg inasmuch as it assumes your values were signed. So, if you compare the bytes 101 (101 in two's complement) with 200 (-56 in two's complement), the former will actually be greater. If that's not what was desired, you should use the equivalent unsigned comparison.

See here for more detail on jump selection, reproduced below for completeness. First the ones where signed-ness is not appropriate:

You need to compare, not assign:

if (strcmp("hello", "hello") == 0)
                             ^

Because you want to check if the result of strcmp("hello", "hello") equals to 0.

About the error:

lvalue required as left operand of assignment

lvalue means an assignable value (variable), and in assignment the left value to the = has to be lvalue (pretty clear).

Both function results and constants are not assignable (rvalues), so they are rvalues. so the order doesn't matter and if you forget to use == you will get this error. (edit:)I consider it a good practice in comparison to put the constant in the left side, so if you write = instead of ==, you will get a compilation error. for example:

int a = 5;
if (a = 0) // Always evaluated as false, no error.
{
    //...
}

vs.

int a = 5;
if (0 = a) // Generates compilation error, you cannot assign a to 0 (rvalue)
{
    //...
}

(see first answer to this question: https://stackoverflow.com/questions/2349378/new-programming-jargon-you-coined)

<a [ngClass]="{'class1':array.status === 'active','class2':array.status === 'idle','class3':array.status === 'inactive',}">

Another method (mentioned in this SO answer) will keep the history in the terminal and give you a very deep track record of the file itself:

git log --follow -p -- file

This will show the entire history of the file (including history beyond renames and with diffs for each change).

In other words, if the file named bar was once named foo, then git log -p bar (without the --follow option) will only show the file's history up to the point where it was renamed -- it won't show the file's history when it was known as foo. Using git log --follow -p bar will show the file's entire history, including any changes to the file when it was known as foo.

SSL certificates are bound to a 'common name', which is usually a fully qualified domain name but can be a wildcard name (eg. *.domain.com) or even an IP address, but it usually isn't.

In your case, you are accessing your LDAP server by a hostname and it sounds like your two LDAP servers have different SSL certificates installed. Are you able to view (or download and view) the details of the SSL certificate? Each SSL certificate will have a unique serial numbers and fingerprint which will need to match. I assume the certificate is being rejected as these details don't match with what's in your certificate store.

Your solution will be to ensure that both LDAP servers have the same SSL certificate installed.

BTW - you can normally override DNS entries on your workstation by editing a local 'hosts' file, but I wouldn't recommend this.

you can use numpy.argsort

or you can do:

test =  [2,3,1,4,5]
idxs = list(zip(*sorted([(val, i) for i, val in enumerate(test)])))[1]

zip will rearange the list so that the first element is test and the second is the idxs.

I had solved it on iPad. Try, if it works also on OSX.

body, html { position: fixed; }

Works only if you have content smaller then screen or you are using some layout framework (Angular Material in my case).

In Angular Material it is great, that you will disable over-scroll effect of whole page, but inner sections <md-content> can be still scrollable.

Cannot be done with pure batch.Check the shortcutJS.bat - it is a jscript/bat hybrid and should be used with .bat extension:

call shortcutJS.bat -linkfile "%~n0.lnk" -target  "%~f0" -linkarguments "some arguments"

With -help you can check the other options (you can set icon , admin permissions and etc.)

There's a couple of ways you can do this. If the onchange listener is a function set via the element.onchange property and you're not bothered about the event object or bubbling/propagation, the easiest method is to just call that function:

element.onchange();

If you need it to simulate the real event in full, or if you set the event via the html attribute or addEventListener/attachEvent, you need to do a bit of feature detection to correctly fire the event:

if ("createEvent" in document) {
    var evt = document.createEvent("HTMLEvents");
    evt.initEvent("change", false, true);
    element.dispatchEvent(evt);
}
else
    element.fireEvent("onchange");

In the meantime, a time-window capability was added. See this link.

I assume you are using the caption feature of Word, that is, captions were not typed in as normal text, but were inserted using Insert > Caption (Word versions before 2007), or References > Insert Caption (in the ribbon of Word 2007 and up). If done correctly, the captions are really 'fields'. You'll know if it is a field if the caption's background turns grey when you put your cursor on them (or is permanently displayed grey).

Captions are fields - Unfortunately fields (like caption fields) are only updated on specific actions, like opening of the document, printing, switching from print view to normal view, etc. The easiest way to force updating of all (caption) fields when you want it is by doing the following:

1. Select all text in your document (easiest way is to press ctrl-a)
2. Press F9, this command tells Word to update all fields in the selection.

Captions are normal text - If the caption number is not a field, I am afraid you'll have to edit the text manually.

It should be noted that you do not have to even use the "replace" method to change the value original value. If you assign one of the hash values for a hash, you are changing the original value.

def my_foo(a_hash)
  a_hash["test"]="reference"
end;

hash = {"test"=>"value"}
my_foo(hash)
puts "Ruby is pass-by-#{hash["test"]}"

Here's my solution for inline comments in between multiple piped commands.

Example uncommented code:

    #!/bin/sh
    cat input.txt \
    | grep something \
    | sort -r

Solution for a pipe comment (using a helper function):

    #!/bin/sh
    pipe_comment() {
        cat - 
    }
    cat input.txt \
    | pipe_comment "filter down to lines that contain the word: something" \
    | grep something \
    | pipe_comment "reverse sort what is left" \
    | sort -r

Or if you prefer, here's the same solution without the helper function, but it's a little messier:

    #!/bin/sh
    cat input.txt \
    | cat - `: filter down to lines that contain the word: something` \
    | grep something \
    | cat - `: reverse sort what is left` \
    | sort -r

As a NOT TO DO - Another way would be to use:

divControl.Attributes.Add("style", "height: number");

But don't use this as its messy and the answer by AviewAnew is the correct way.

One way would be using slice, like follow:

var id="ctl03_Tabs1";
var temp=id.slice(-5);

so the value of temp would be "Tabs1".

since your form has a field called 'q', leaving it blank still sends an empty string.

try

if 'q' in request.GET and request.GET['q'] != "" :
     message
else
     error message

Try this:

void drawInitialNim(int num1, int num2, int num3){
    int board[3][50] = {0}; // This is a local variable. It is not possible to use it after returning from this function. 

    int i, j, k;

    for(i=0; i<num1; i++)
        board[0][i] = 'O';
    for(i=0; i<num2; i++)
        board[1][i] = 'O';
    for(i=0; i<num3; i++)
        board[2][i] = 'O';

    for (j=0; j<3;j++) {
        for (k=0; k<50; k++) {
            if(board[j][k] != 0)
                printf("%c", board[j][k]);
        }
        printf("\n");
    }
}

Jrad solution is good but I don't like that he doesn't use array copy. Internally System.arraycopy() does a native call so you will a get faster results.

public static int[] addPos(int[] a, int index, int num) {
    int[] result = new int[a.length];
    System.arraycopy(a, 0, result, 0, index);
    System.arraycopy(a, index, result, index + 1, a.length - index - 1);
    result[index] = num;
    return result;
}

Not a for each exactly, but you can do nested SQL

SELECT 
    distinct a.ID, 
    a.col2, 
    (SELECT 
        SUM(b.size) 
    FROM 
        tableb b 
    WHERE 
        b.id = a.col3)
FROM
    tablea a

You want matplotlib.pcolor:

import numpy as np 
from pandas import DataFrame
import matplotlib.pyplot as plt

index = ['aaa', 'bbb', 'ccc', 'ddd', 'eee']
columns = ['A', 'B', 'C', 'D']
df = DataFrame(abs(np.random.randn(5, 4)), index=index, columns=columns)

plt.pcolor(df)
plt.yticks(np.arange(0.5, len(df.index), 1), df.index)
plt.xticks(np.arange(0.5, len(df.columns), 1), df.columns)
plt.show()

This gives:

Yarn is a recent package manager that probably deserves to be mentioned.
So, here it is: https://yarnpkg.com/

As far as I know it can fetch both npm and bower dependencies and has other appreciated features.

another alternative is to use a form replacement script/library. They usually hide the original element and replace them with a div or span, which you can style in whatever way you like.

Examples are:

Your datatype for @location nchar(20) should be @location nvarchar(20), since nChar has a fixed length (filled with Spaces).
If Location is nchar too you will have to convert it:

 ... Cast(Location as nVarchar(200)) like '%'+@location+'%' ...   

To enable nullable parameters with and AND condition just use IsNull or Coalesce for comparison, which is not needed in your example using OR.

e.g. if you would like to compare for Location AND Date and Time.

@location nchar(20),
@time time,
@date date
as
select DonationsTruck.VechileId, Phone, Location, [Date], [Time]
from Vechile, DonationsTruck
where Vechile.VechileId = DonationsTruck.VechileId
and (((Location like '%'+IsNull(@location,Location)+'%')) and [Date]=IsNUll(@date,date) and [Time] = IsNull(@time,Time))

From the documentation:

contentType (default: 'application/x-www-form-urlencoded; charset=UTF-8')

Type: String

When sending data to the server, use this content type. Default is "application/x-www-form-urlencoded; charset=UTF-8", which is fine for most cases. If you explicitly pass in a content-type to $.ajax(), then it'll always be sent to the server (even if no data is sent). If no charset is specified, data will be transmitted to the server using the server's default charset; you must decode this appropriately on the server side.

and:

dataType (default: Intelligent Guess (xml, json, script, or html))

Type: String

The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response (an XML MIME type will yield XML, in 1.4 JSON will yield a JavaScript object, in 1.4 script will execute the script, and anything else will be returned as a string).

They're essentially the opposite of what you thought they were.

They are two different metrics to evaluate your model's performance usually being used in different phases.

Loss is often used in the training process to find the "best" parameter values for your model (e.g. weights in neural network). It is what you try to optimize in the training by updating weights.

Accuracy is more from an applied perspective. Once you find the optimized parameters above, you use this metrics to evaluate how accurate your model's prediction is compared to the true data.

Let us use a toy classification example. You want to predict gender from one's weight and height. You have 3 data, they are as follows:(0 stands for male, 1 stands for female)

y1 = 0, x1_w = 50kg, x2_h = 160cm;

y2 = 0, x2_w = 60kg, x2_h = 170cm;

y3 = 1, x3_w = 55kg, x3_h = 175cm;

You use a simple logistic regression model that is y = 1/(1+exp-(b1*x_w+b2*x_h))

How do you find b1 and b2? you define a loss first and use optimization method to minimize the loss in an iterative way by updating b1 and b2.

In our example, a typical loss for this binary classification problem can be: (a minus sign should be added in front of the summation sign)

We don't know what b1 and b2 should be. Let us make a random guess say b1 = 0.1 and b2 = -0.03. Then what is our loss now?

so the loss is

Then you learning algorithm (e.g. gradient descent) will find a way to update b1 and b2 to decrease the loss.

What if b1=0.1 and b2=-0.03 is the final b1 and b2 (output from gradient descent), what is the accuracy now?

Let's assume if y_hat >= 0.5, we decide our prediction is female(1). otherwise it would be 0. Therefore, our algorithm predict y1 = 1, y2 = 1 and y3 = 1. What is our accuracy? We make wrong prediction on y1 and y2 and make correct one on y3. So now our accuracy is 1/3 = 33.33%

PS: In Amir's answer, back-propagation is said to be an optimization method in NN. I think it would be treated as a way to find gradient for weights in NN. Common optimization method in NN are GradientDescent and Adam.

This solution essentially draws the image as 'aspect fit' within the given rect.

CGSize itemSize = CGSizeMake(80, 80);
UIGraphicsBeginImageContextWithOptions(itemSize, NO, UIScreen.mainScreen.scale);
UIImage *image = cell.imageView.image;

CGRect imageRect;
if(image.size.height > image.size.width) {
    CGFloat width = itemSize.height * image.size.width / image.size.height;
    imageRect = CGRectMake((itemSize.width - width) / 2, 0, width, itemSize.height);
} else {
    CGFloat height = itemSize.width * image.size.height / image.size.width;
    imageRect = CGRectMake(0, (itemSize.height - height) / 2, itemSize.width, height);
}

[cell.imageView.image drawInRect:imageRect];
cell.imageView.image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

How about a custom interval-tree structure? You'll have to tweak it a little bit to define what it means for two intervals to "overlap" in your domain.

This question might help you find an off-the-shelf interval-tree implementation in C#.

Assuming you are dealing with a JSON-string in the input, you can parse it using the json package, see the documentation.

In the specific example you posted you would need

x = json.loads("""{
 "accountWide": true,
 "criteria": [
     {
         "description": "some description",
         "id": 7553,
         "max": 1,
         "orderIndex": 0
     }
  ]
 }""")
description = x['criteria'][0]['description']
id = x['criteria'][0]['id']
max = x['criteria'][0]['max']

One addition: It should be noted that, in case "/tmp" is the directory where the session data is stored (which seems to be the default value), the sessions will not persist after reboot of that web server, as "/tmp" is often purged during reboot. The concept of a client-wise persistence stands and falls with the persistence of the storage on the server - which might fail if the "/tmp" directory is used for session data.

If you have the need to use other libraries in projects --typescript-- not just in projects - angle - you can look for tds's (TypeScript Declaration File) that are depares and that have information of methods, types, functions, etc. , which can be used by TypeScript, usually without the need for import. declare var is the last resource

npm install @types/lib-name --save-dev

I don't know if this is really any different, but rather than iterate over the query cursor, you could do something like this:

query.exec(function (err, results){
  if (err) res.writeHead(500, err.message)
  else if (!results.length) res.writeHead(404);
  else {
    res.writeHead(200, { 'Content-Type': 'application/json' });
    res.write(JSON.stringify(results.map(function (msg){ return {msgId: msg.fileName}; })));
  }
  res.end();
});

Child Component

Use this.$emit('event_name') to send an event to the parent component.

Parent Component

In order to listen to that event in the parent component, we do v-on:event_name and a method (ex. handleChange) that we want to execute on that event occurs

Done :)

items[node.ind] = items[node.ind]._replace(v=node.v)

(Note: Don't be discouraged to use this solution because of the leading underscore in the function _replace. Specifically for namedtuple some functions have leading underscore which is not for indicating they are meant to be "private")

The other big difference is Abandon does not remove items immediately, but when it does then cleanup it does a loop over session items to check for STA COM objects it needs to handle specially. And this can be a problem.

Under high load it's possible for two (or more) requests to make it to the server for the same session (that is two requests with the same session cookie). Their execution will be serialized, but since Abandon doesn't clear out the items synchronously but rather sets a flag it's possible for both requests to run, and both requests to schedule a work item to clear out session "later". Both these work items can then run at the same time, and both are checking the session objects, and both are clearing out the array of objects, and what happens when you have two things iterating over a list and changing it?? Boom! And since this happens in a queueuserworkitem callback and is NOT done in a try/catch (thanks MS), it will bring down your entire app domain. Been there.

In newer versions of Eclipse the global configuration file can be set in

Windows > Preferences > Maven > User Settings > Global Settings

Don't beat me why global settings can be configured in user settings... Probably because of the same reason why you need to press "Start" to shutdown your PC on Windows... :D
