I mostly build large scale, high availability type systems, so my answer is biased towards looking at it from a production support standpoint; that said, we assign roughly as follows:

• error: the system is in distress, customers are probably being affected (or will soon be) and the fix probably requires human intervention. The "2AM rule" applies here- if you're on call, do you want to be woken up at 2AM if this condition happens? If yes, then log it as "error".

• warn: an unexpected technical or business event happened, customers may be affected, but probably no immediate human intervention is required. On call people won't be called immediately, but support personnel will want to review these issues asap to understand what the impact is. Basically any issue that needs to be tracked but may not require immediate intervention.

• info: things we want to see at high volume in case we need to forensically analyze an issue. System lifecycle events (system start, stop) go here. "Session" lifecycle events (login, logout, etc.) go here. Significant boundary events should be considered as well (e.g. database calls, remote API calls). Typical business exceptions can go here (e.g. login failed due to bad credentials). Any other event you think you'll need to see in production at high volume goes here.

• debug: just about everything that doesn't make the "info" cut... any message that is helpful in tracking the flow through the system and isolating issues, especially during the development and QA phases. We use "debug" level logs for entry/exit of most non-trivial methods and marking interesting events and decision points inside methods.

• trace: we don't use this often, but this would be for extremely detailed and potentially high volume logs that you don't typically want enabled even during normal development. Examples include dumping a full object hierarchy, logging some state during every iteration of a large loop, etc.

As or more important than choosing the right log levels is ensuring that the logs are meaningful and have the needed context. For example, you'll almost always want to include the thread ID in the logs so you can follow a single thread if needed. You may also want to employ a mechanism to associate business info (e.g. user ID) to the thread so it gets logged as well. In your log message, you'll want to include enough info to ensure the message can be actionable. A log like " FileNotFound exception caught" is not very helpful. A better message is "FileNotFound exception caught while attempting to open config file: /usr/local/app/somefile.txt. userId=12344."

There are also a number of good logging guides out there... for example, here's an edited snippet from JCL (Jakarta Commons Logging):

• error - Other runtime errors or unexpected conditions. Expect these to be immediately visible on a status console.
• warn - Use of deprecated APIs, poor use of API, 'almost' errors, other runtime situations that are undesirable or unexpected, but not necessarily "wrong". Expect these to be immediately visible on a status console.
• info - Interesting runtime events (startup/shutdown). Expect these to be immediately visible on a console, so be conservative and keep to a minimum.
• debug - detailed information on the flow through the system. Expect these to be written to logs only.
• trace - more detailed information. Expect these to be written to logs only.

Update: For an all configuration based approach using Groovy see Dean Hiller's answer.

You can do some interesting things with Logback filters. The below configuration will only print warn and error messages to stderr, and everything else to stdout.

logback.xml

<appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
  <target>System.out</target>
  <filter class="com.foo.StdOutFilter" />
   ...
</appender>

<appender name="stderr" class="ch.qos.logback.core.ConsoleAppender">
  <target>System.err</target>
  <filter class="com.foo.ErrOutFilter" />
   ...
</appender>

<logger name="mylogger" level="debug">
    <appender-ref ref="stdout" />
    <appender-ref ref="stderr" />
</logger>

com.foo.StdOutFilter

public class StdOutFilter extends ch.qos.logback.core.filter.AbstractMatcherFilter
{

    @Override
    public FilterReply decide(Object event)
    {
        if (!isStarted())
        {
            return FilterReply.NEUTRAL;
        }

        LoggingEvent loggingEvent = (LoggingEvent) event;

        List<Level> eventsToKeep = Arrays.asList(Level.TRACE, Level.DEBUG, Level.INFO);
        if (eventsToKeep.contains(loggingEvent.getLevel()))
        {
            return FilterReply.NEUTRAL;
        }
        else
        {
            return FilterReply.DENY;
        }
    }

}

com.foo.ErrOutFilter

public class ErrOutFilter extends ch.qos.logback.core.filter.AbstractMatcherFilter
{

    @Override
    public FilterReply decide(Object event)
    {
        if (!isStarted())
        {
            return FilterReply.NEUTRAL;
        }

        LoggingEvent loggingEvent = (LoggingEvent) event;

        List<Level> eventsToKeep = Arrays.asList(Level.WARN, Level.ERROR);
        if (eventsToKeep.contains(loggingEvent.getLevel()))
        {
            return FilterReply.NEUTRAL;
        }
        else
        {
            return FilterReply.DENY;
        }
    }

}

Not exactly answering your question, but if you could move away from your self-made wrapper then there is Simple Logging Facade for Java (SLF4J) which Hibernate has now switched to (instead of commons logging).

SLF4J suffers from none of the class loader problems or memory leaks observed with Jakarta Commons Logging (JCL).

SLF4J supports JDK logging, log4j and logback. So then it should be fairly easy to switch from log4j to logback when the time is right.

Edit: Aplogies that I hadn't made myself clear. I was suggesting using SLF4J to isolate yourself from having to make a hard choice between log4j or logback.

You are mixing the 1.5.6 version of the jcl bridge with the 1.6.0 version of the slf4j-api; this won't work because of a few changes in 1.6.0. Use the same versions for both, i.e. 1.6.1 (the latest). I use the jcl-over-slf4j bridge all the time and it works fine.

I assume you are using logback (from the configuration file).

From logback manual, I see

Logger rootLogger = LoggerFactory.getLogger(org.slf4j.Logger.ROOT_LOGGER_NAME);

Perhaps this can help you change the value?

I can also confirm this error.

Workaround: is to use external maven inside m2eclipse, instead of it's embedded maven.

That is done in three steps:

1 Install maven on local machine (the test-machine was Ubuntu 10.10)

mvn --version

Apache Maven 2.2.1 (rdebian-4) Java version: 1.6.0_20 Java home: /usr/lib/jvm/java-6-openjdk/jre Default locale: de_DE, platform encoding: UTF-8 OS name: "linux" version: "2.6.35-32-generic" arch: "amd64" Family: "unix"

2 Run maven externally link how to run maven from console

> cd path-to-pom.xml
> mvn test

3 inside m2eclipse: switch from embedded maven to local maven

• find out where local maven home installation dir is (mvn --version, or google for your MAVEN_HOME, for me this helped me that is /usr/share/maven2 )
• in eclipse Menu->Window->Preferences->Maven->Installation-> enter that string. Then you should have switched to your new external maven.
• then run your Project as e.g. "maven test".

The error-message should be gone.

I had same problem and finally found my mistake :) I used this command for compiling and it worked correctly:

javac -cp "/home/omidmohebbi/AAAATest/jars/core-1.7.jar:/home/omidmohebbi/AAAATest/jars/javase-1.7.jar:/home/omidmohebbi/AAAATest/jars/qrgen-1.2.jar" qrcode.java

But this command did not work for me (I could not find or load the main class, qrcode):

java -cp "/home/omidmohebbi/AAAATest/jars/core-1.7.jar:/home/omidmohebbi/AAAATest/jars/javase-1.7.jar:/home/omidmohebbi/AAAATest/jars/qrgen-1.2.jar" qrcode

Finally I just added the ':' character at end of the classpath and the problem was solved:

java -cp "/home/omidmohebbi/AAAATest/jars/core-1.7.jar:/home/omidmohebbi/AAAATest/jars/javase-1.7.jar:/home/omidmohebbi/AAAATest/jars/qrgen-1.2.jar:" qrcode

Very simple:

function myfunction($products, $field, $value)
{
   foreach($products as $key => $product)
   {
      if ( $product[$field] === $value )
         return $key;
   }
   return false;
}

I think you need the SCHEDULER_ADMIN role to see the dba_scheduler tables (however this may grant you too may rights)

see: http://download.oracle.com/docs/cd/B28359_01/server.111/b28310/schedadmin001.htm

You can use WooCommerce AJAX Product Filter. You can also watch how the plugin is used for product filtering.

Here is a screenshot:

Here's a detailed explanation about the calculation of MaxClients and MaxRequestsPerChild

http://web.archive.org/web/20160415001028/http://www.genericarticles.com/mediawiki/index.php?title=How_to_optimize_apache_web_server_for_maximum_concurrent_connections_or_increase_max_clients_in_apache

ServerLimit 16
StartServers 2
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25

First of all, whenever an apache is started, it will start 2 child processes which is determined by StartServers parameter. Then each process will start 25 threads determined by ThreadsPerChild parameter so this means 2 process can service only 50 concurrent connections/clients i.e. 25x2=50. Now if more concurrent users comes, then another child process will start, that can service another 25 users. But how many child processes can be started is controlled by ServerLimit parameter, this means that in the configuration above, I can have 16 child processes in total, with each child process can handle 25 thread, in total handling 16x25=400 concurrent users. But if number defined in MaxClients is less which is 200 here, then this means that after 8 child processes, no extra process will start since we have defined an upper cap of MaxClients. This also means that if I set MaxClients to 1000, after 16 child processes and 400 connections, no extra process will start and we cannot service more than 400 concurrent clients even if we have increase the MaxClient parameter. In this case, we need to also increase ServerLimit to 1000/25 i.e. MaxClients/ThreadsPerChild=40 So this is the optmized configuration to server 1000 clients

<IfModule mpm_worker_module>
    ServerLimit          40
    StartServers          2
    MaxClients          1000
    MinSpareThreads      25
    MaxSpareThreads      75 
    ThreadsPerChild      25
    MaxRequestsPerChild   0
</IfModule>

If the lines in the file end with \r\n\000 then what works is to delete the \n\000 then replace the \r with \n.

tr -d '\n\000' <infile | tr '\r' '\n' >outfile

Open chrome, go to chrome://settings/languages

On the left, you should see a list of languages. Use mouse to drag the language you want to the top, that will change the order for the values in Accept-language of requests.

If you still don't see the language you prefer, it may be cookies. Go to cookies and clean it up you should be good.

If expecting JSON back, the simplest way to get it:

$data = json_decode($response->getBody()); // returns an object

// OR

$data = json_decode($response->getBody(), true); // returns an array

json_decode() will automatically cast the body to string, so there is no need to call getContents().

Spaces in the Commend Prompt (in a VBA Shell command code line)

I had a very similar problem which ended up being a space in the command prompt when automating via VBA to get the contents from the command window into a text file. This Thread was one of many I caught along the way that didn’t quite get me the solution.

So this may help others with a similar problem: Since the syntax with quotes is always difficult to get right , I think showing some specific examples is always useful. The additional problem you get using the command prompt in VBA via the Shell thing, is that the code line often won’t error when something goes wrong: in fact a blink of the black commend window misleads into thinking something was done.

As example… say I have a Folder, with a text file in it like at

C:\Alans Folder\test1.txt ( https://imgur.com/FELSdB6 )

The space there in the folder name gives the problem.

Something like this would work, assuming the Folder, AlansFolder, exists

Sub ShellBlackCommandPromptWindowAutomatingCopyingWindowContent()
 Shell "cmd.exe /c ""ipconfig /all > C:\AlansFolder\test1.txt"""
End Sub

This won’t work. (It won’t error).

Sub ShellBlackCommandPromptWindowAutomatingCopyingWindowContent()
 Shell "cmd.exe /c ""ipconfig /all > C:\Alans Folder\test1.txt"""
End Sub

Including quote pairs around the path will make it work

Sub ShellBlackCommandPromptWindowAutomatingCopyingWindowContent()
 Shell "cmd.exe /c ""ipconfig /all > ""C:\Alans Folder\test1.txt"""""
End Sub

( By the way, if the text file does not exist, then it will be made).

With the benefit of hindsight, we can see that my solution does tie up approximately with some already given..

Converting that code line to a manual given command we would have

ipconfig /all > "C:\Alans Folder\test1.txt"

That seems to work

This works also

ipconfig /all > C:\AlansFolder\test1.txt

This doesn’t

ipconfig /all > C:\Alans Folder\test1.txt

This final form also works and ties up with the solution from sacra ….” You have to add quotation marks around each path and also enclose the whole command in quotation marks “ …..

cmd.exe /c "ipconfig /all > "C:\Alans Folder\test1.txt""

Just to quote Boot Docs:

You can set spring.data.mongodb.uri property to change the url, or alternatively specify a host/port. For example, you might declare the following in your application.properties:

spring.data.mongodb.host=mongoserver
spring.data.mongodb.port=27017

All available options for spring.data.mongodb prefix are fields of MongoProperties:

private String host;

private int port = DBPort.PORT;

private String uri = "mongodb://localhost/test";

private String database;

private String gridFsDatabase;

private String username;

private char[] password;

I got the same error message when using sklearn with pandas. My solution is to reset the index of my dataframe df before running any sklearn code:

df = df.reset_index()

I encountered this issue many times when I removed some entries in my df, such as

df = df[df.label=='desired_one']

Besides the mentioned fact that JSX tags are not standard javascript, the reason I use .jsx extension is because with it Emmet still works in the editor - you know, that useful plugin that expands html code, for example ul>li into

<ul>
  <li></li>
</ul>

yes you can by using static class. like this:

static class Global
{
    private static string _globalVar = "";

    public static string GlobalVar
    {
        get { return _globalVar; }
        set { _globalVar = value; }
    }
}

and for using any where you can write:

GlobalClass.GlobalVar = "any string value"

Command where or frame can be used. where command will give more info with the function name

I use getActionCommand() to hear buttons. I apply the setActionCommand() to each button so that I can hear whenever an event is execute with event.getActionCommand("The setActionCommand() value of the button").

I use getSource() for JRadioButtons for example. I write methods that returns each JRadioButton so in my Listener Class I can specify an action each time a new JRadioButton is pressed. So for example:

public class SeleccionListener implements ActionListener, FocusListener {}

So with this I can hear button events and radioButtons events. The following are examples of how I listen each one:

public void actionPerformed(ActionEvent event) {
    if (event.getActionCommand().equals(GUISeleccion.BOTON_ACEPTAR)) {
        System.out.println("Aceptar pressed");
    }

In this case GUISeleccion.BOTON_ACEPTAR is a "public static final String" which is used in JButtonAceptar.setActionCommand(BOTON_ACEPTAR).

public void focusGained(FocusEvent focusEvent) {
    if (focusEvent.getSource().equals(guiSeleccion.getJrbDat())){
        System.out.println("Data radio button");
    }

In this one, I get the source of any JRadioButton that is focused when the user hits it. guiSeleccion.getJrbDat() returns the reference to the JRadioButton that is in the class GUISeleccion (this is a Frame)

Dead simple. No plugins needed.

var $container = $('div'),
    $scrollTo = $('#row_8');

$container.scrollTop(
    $scrollTo.offset().top - $container.offset().top + $container.scrollTop()
);

// Or you can animate the scrolling:
$container.animate({
    scrollTop: $scrollTo.offset().top - $container.offset().top + $container.scrollTop()
});?

Here is a working example.

Documentation for scrollTop.

type

%matplotlib qt

when you want graphs in a separate window and

%matplotlib inline

when you want an inline plot

can anyone explain why

because your regular expression does match the input. It's just that the input also includes the extra characters. You included '^' to signify the beginning of line, but (as Andy said) you should include '$' to signify the end of line.

If you start your regex with '^' and end it with '$', then it will only match lines that only match your regex.

By starting your regex with '^' and not ending it with '$', you match lines that start with a sequence matching your regex, but lines can have anything else trailing the matching sequence.

After reading through the posts, I find some very relevant comments. In short, the confusion between the URL and URI definitions is based in part on which definition depends on which and also informal use of the word URI in software development.

By definition URL is a subset of URI [RFC2396]. URI contain URN and URL. Both URI and URL each have their own specific syntax that confers upon them the status of being either URI or URL. URN are for uniquely identifying a resource while URL are for locating a resource. Note that a resource can have more than one URL but only a single URN.[RFC2611]

As web developers and programmers we will almost always be concerned with URL and therefore URI. Now a URL is specifically defined to have all the parts scheme:scheme-specific-part, like for example https://stackoverflow.com/questions. This is a URL and it is also a URI. Now consider a relative link embedded in the page such as ../index.html. This is no longer a URL by definition. It is still what is referred to as a "URI-reference" [RFC2396].

I believe that when the word URI is used to refer to relative paths, "URI-reference" is actually what is being thought of. So informally, software systems use URI to refer to relative pathing and URL for the absolute address. So in this sense, a relative path is no longer a URL but still URI.

Here is where the repair button is:

If you want your script to return values, just do return [1,2,3] from a function wrapping your code but then you'd have to import your script from another script to even have any use for that information:

Return values (from a wrapping-function)

(again, this would have to be run by a separate Python script and be imported in order to even do any good):

import ...
def main():
    # calculate stuff
    return [1,2,3]

Exit codes as indicators

(This is generally just good for when you want to indicate to a governor what went wrong or simply the number of bugs/rows counted or w/e. Normally 0 is a good exit and >=1 is a bad exit but you could inter-prate them in any way you want to get data out of it)

import sys
# calculate and stuff
sys.exit(100)

And exit with a specific exit code depending on what you want that to tell your governor. I used exit codes when running script by a scheduling and monitoring environment to indicate what has happened.

(os._exit(100) also works, and is a bit more forceful)

Stdout as your relay

If not you'd have to use stdout to communicate with the outside world (like you've described). But that's generally a bad idea unless it's a parser executing your script and can catch whatever it is you're reporting to.

import sys
# calculate stuff
sys.stdout.write('Bugs: 5|Other: 10\n')
sys.stdout.flush()
sys.exit(0)

Are you running your script in a controlled scheduling environment then exit codes are the best way to go.

Files as conveyors

There's also the option to simply write information to a file, and store the result there.

# calculate
with open('finish.txt', 'wb') as fh:
    fh.write(str(5)+'\n')

And pick up the value/result from there. You could even do it in a CSV format for others to read simplistically.

Sockets as conveyors

If none of the above work, you can also use network sockets locally *(unix sockets is a great way on nix systems). These are a bit more intricate and deserve their own post/answer. But editing to add it here as it's a good option to communicate between processes. Especially if they should run multiple tasks and return values.

You and String.format() will be new best friends!

https://docs.oracle.com/javase/1.5.0/docs/api/java/util/Formatter.html#syntax

 String.format("%.2f", (double)value);

In case you are using application.yml add the Following lines to it

server:
     port: 9000

and of course 0 for random port.

Of course:

curl http://example.com:11740
curl https://example.com:11740

Port 80 and 443 are just default port numbers.

A simpler version of one of the above answers. Column A is the key.
Yes, it needs a helper column.  That's column K.
1) Set first cell in table to TRUE (K8)
2) On second row at K9, and to end of table (K99), paste: =IF(A8=A9,K8,NOT(K8))
This gives a pattern of TRUE...TRUE, FALSE...FALSE,...
3) Select key column A1:A99, or whole table A1:K99
4) Set Home/Conditional/New Rule/Formula  =K8
5) Format as you wish for the TRUE cells
6) Select the range from (3) and Right-click Format White (or whatever
background color you want) for the FALSE cells

Note that this solution (and the others) have a major flaw, in that this
highlighting doesn't work properly when you have filters active in your
table.  I want that fix :)

If your shell supports it, would something like this work ?

javac com/**/*.java 

If your shell does not support **, then maybe

javac com/*/*/*.java

works (for all packages with 3 components - adapt for more or less).

So none of the above stuff worked for me. Except this: edit httpd.conf,

find the line

Listen 80 

and change to

listen 0.0.0.0:80 

if you are running windows 8, its got something to do with using ipv6 instead of ipv4

try

<a href="#" _x000D_
   onclick="location='http://example.com/submit.php?url='+escape(location)"_x000D_
   >click here</a>

I came here because I had funny-char-syndrome on my requests output. I thought response.text would give me a properly decoded string, but in the output I found funny double-chars where German umlauts should have been.

Turns out response.encoding was empty somehow and so response did not know how to properly decode the content and just treated it as ASCII (I guess).

My solution was to get the raw bytes with 'response.content' and manually apply decode('utf_8') to it. The result was schöne Umlaute.

According to the documentation, the different algorithms used by SecureRandom are, in order of preference:

• On most *NIX systems
  1. NativePRNG
  2. SHA1PRNG
  3. NativePRNGBlocking
  4. NativePRNGNonBlocking
• On Windows systems
  1. SHA1PRNG
  2. Windows-PRNG

Since you asked about Linux, I'm ignoring the Windows implementation, and also SunPKCS11 which is only really available on Solaris, unless you installed it yourself — and then you wouldn't be asking this question.

According to those same documentation, what these algorithms use are

SHA1PRNG
Initial seeding is currently done via a combination of system attributes and the java.security entropy gathering device.

NativePRNG
nextBytes() uses /dev/urandom
generateSeed() uses /dev/random

NativePRNGBlocking
nextBytes() and generateSeed() use /dev/random

NativePRNGNonBlocking
nextBytes() and generateSeed() use /dev/urandom

That means if you use SecureRandom random = new SecureRandom(), it goes down that list until it finds one that works, which will typically be NativePRNG. And that means that it seeds itself from /dev/random (or uses that if you explicitly generate a seed), then uses /dev/urandom for getting the next bytes, ints, double, booleans, what-have-yous.

Since /dev/random is blocking (it blocks until it has enough entropy in the entropy pool), that may impede performance.

One solution to that is using something like haveged to generate enough entropy, another solution is using /dev/urandom instead. While you could set that for the entire jvm, a better solution is doing it for this specific instance of SecureRandom, by using SecureRandom random = SecureRandom.getInstance("NativePRNGNonBlocking"). Note that that method can throw a NoSuchAlgorithmException if NativePRNGNonBlocking is unavailable, so be prepared to fallback to the default.

SecureRandom random;
try {
    random = SecureRandom.getInstance("NativePRNGNonBlocking");
} catch (NoSuchAlgorithmException nsae) {
    random = new SecureRandom();
}

Also note that on other *nix systems, /dev/urandom may behave differently.

Is /dev/urandom random enough?

Conventional wisdom has it that only /dev/random is random enough. However, some voices differ. In "The Right Way to Use SecureRandom" and "Myths about /dev/urandom", it is argued that /dev/urandom/ is just as good.

The users over on the Information Security stack agree with that. Basically, if you have to ask, /dev/urandom is fine for your purpose.

An adventage of use ExpectedException Rule (version 4.7) is that you can test exception message and not only the expected exception.

And using Matchers, you can test the part of message you are interested:

exception.expectMessage(containsString("income: -1000.0"));

if you are developing in android studio and refactored the package name then you should change the package name in android manifest and app gradle file.

 applicationId "change here your package name"

and in manifest file

 package="change here your package name"

And the Postgres equivalent (second line is mandatory only if you want "id" to be a key):

ALTER TABLE tableName ADD id SERIAL;
ALTER TABLE tableName ADD PRIMARY KEY (id);

Or you can just run the following command and you will see all databases of the Redis instance without firing up redis-cli:

$ redis-cli INFO | grep ^db
db0:keys=1500,expires=2
db1:keys=200000,expires=1
db2:keys=350003,expires=1

Besides using one of the default formats you can specify any size you want in the unit you specify.

For example:

// Document of 210mm wide and 297mm high
new jsPDF('p', 'mm', [297, 210]);
// Document of 297mm wide and 210mm high
new jsPDF('l', 'mm', [297, 210]);
// Document of 5 inch width and 3 inch high
new jsPDF('l', 'in', [3, 5]);

The 3rd parameter of the constructor can take an array of the dimensions. However they do not correspond to width and height, instead they are long side and short side (or flipped around).

Your 1st parameter (landscape or portrait) determines what becomes the width and the height.

In the sourcecode on GitHub you can see the supported units (relative proportions to pt), and you can also see the default page formats (with their sizes in pt).

I just found a solution to the problem here:

http://willcodeforcoffee.com/2007/01/31/cakephp-error-500-too-many-redirects/

The .htaccess file in webroot should look like:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

instead of this:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /projectname
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

1. You could call std::terminate() from any thread and the thread you're referring to will forcefully end.

2. You could arrange for ~thread() to be executed on the object of the target thread, without a intervening join() nor detach() on that object. This will have the same effect as option 1.

3. You could design an exception which has a destructor which throws an exception. And then arrange for the target thread to throw this exception when it is to be forcefully terminated. The tricky part on this one is getting the target thread to throw this exception.

Options 1 and 2 don't leak intra-process resources, but they terminate every thread.

Option 3 will probably leak resources, but is partially cooperative in that the target thread has to agree to throw the exception.

There is no portable way in C++11 (that I'm aware of) to non-cooperatively kill a single thread in a multi-thread program (i.e. without killing all threads). There was no motivation to design such a feature.

A std::thread may have this member function:

native_handle_type native_handle();

You might be able to use this to call an OS-dependent function to do what you want. For example on Apple's OS's, this function exists and native_handle_type is a pthread_t. If you are successful, you are likely to leak resources.

// get image from upload-image page 
public function postUplodeImage(Request $request)

    $this->validate($request, [
  // check validtion for image or file
        'uplode_image_file' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:2048',
    ]);
// rename image name or file name 

    $getimageName = time().'.'.$request->uplode_image_file->getClientOriginalExtension();
    $request->uplode_image_file->move(public_path('images'), $getimageName);
    return back()
        ->with('success','images Has been You uploaded successfully.')
        ->with('image',$getimageName);
}

The BFG is specifically designed for removing unwanted data like big files or passwords from Git repos, so it has a simple flag that will remove any large historical (not-in-your-current-commit) files: '--strip-blobs-bigger-than'

$ java -jar bfg.jar --strip-blobs-bigger-than 100M

If you'd like to specify files by name, you can do that too:

$ java -jar bfg.jar --delete-files *.mp4

The BFG is 10-1000x faster than git filter-branch, and generally much easier to use - check the full usage instructions and examples for more details.

If your MySQL server process is listening on 127.0.0.1 or ::1 only then you will not be able to connect remotely. If you have a bind-address setting in /etc/my.cnf this might be the source of the problem.

You will also have to add privileges for a non-localhost user as well.

http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.remoteendpoint.aspx

You can then call the IPEndPoint..::.Address method to retrieve the remote IPAddress, and the IPEndPoint..::.Port method to retrieve the remote port number.

More from the link (fixed up alot heh):

Socket s;

IPEndPoint remoteIpEndPoint = s.RemoteEndPoint as IPEndPoint;
IPEndPoint localIpEndPoint = s.LocalEndPoint as IPEndPoint;

if (remoteIpEndPoint != null)
{
    // Using the RemoteEndPoint property.
    Console.WriteLine("I am connected to " + remoteIpEndPoint.Address + "on port number " + remoteIpEndPoint.Port);
}

if (localIpEndPoint != null)
{
    // Using the LocalEndPoint property.
    Console.WriteLine("My local IpAddress is :" + localIpEndPoint.Address + "I am connected on port number " + localIpEndPoint.Port);
}

I created a function that tests a users input for Youtube, Soundcloud or Vimeo embed ID's, to be able to create a more continous design with embedded media. This function detects and returns an object withtwo properties: "type" and "id". Type can be either "youtube", "vimeo" or "soundcloud" and the "id" property is the unique media id.

On the site I use a textarea dump, where the user can paste in any type of link or embed code, including the iFrame-embedding of both vimeo and youtube.

function testUrlForMedia(pastedData) {
var success = false;
var media   = {};
if (pastedData.match('http://(www.)?youtube|youtu\.be')) {
    if (pastedData.match('embed')) { youtube_id = pastedData.split(/embed\//)[1].split('"')[0]; }
    else { youtube_id = pastedData.split(/v\/|v=|youtu\.be\//)[1].split(/[?&]/)[0]; }
    media.type  = "youtube";
    media.id    = youtube_id;
    success = true;
}
else if (pastedData.match('http://(player.)?vimeo\.com')) {
    vimeo_id = pastedData.split(/video\/|http:\/\/vimeo\.com\//)[1].split(/[?&]/)[0];
    media.type  = "vimeo";
    media.id    = vimeo_id;
    success = true;
}
else if (pastedData.match('http://player\.soundcloud\.com')) {
    soundcloud_url = unescape(pastedData.split(/value="/)[1].split(/["]/)[0]);
    soundcloud_id = soundcloud_url.split(/tracks\//)[1].split(/[&"]/)[0];
    media.type  = "soundcloud";
    media.id    = soundcloud_id;
    success = true;
}
if (success) { return media; }
else { alert("No valid media id detected"); }
return false;
}

      System.out.println(getReverser(input, input.length()-1));
   }
}

Try this in your alice repository (before pushing):

git config push.default tracking

Or, configure it as the default for your user with git config --global ….

git push does default to the origin repository (which is normally the repository from which you cloned the current repository), but it does not default to pushing the current branch—it defaults to pushing only branches that exist in both the source repository and the destination repository.

The push.default configuration variable (see git-config(1)) controls what git push will push when it is not given any “refspec” arguments (i.e. something after a repository name). The default value gives the behavior described above.

Here are possible values for push.default:

• nothing
  This forces you to supply a “refspec”.

• matching (the default)
  This pushes all branches that exist in both the source repository and the destination repository.
  This is completely independent of the branch that is currently checked out.

• upstream or tracking
  (Both values mean the same thing. The later was deprecated to avoid confusion with “remote-tracking” branches. The former was introduced in 1.7.4.2, so you will have to use the latter if you are using Git 1.7.3.1.)
  These push the current branch to the branch specified by its “upstream” configuration.

• current
  This pushes the current branch to the branch of the same name at the destination repository.

  These last two end up being the same for common cases (e.g. working on local master which uses origin/master as its upstream), but they are different when the local branch has a different name from its “upstream” branch:

  git checkout master
  # hack, commit, hack, commit
  
  # bug report comes in, we want a fix on master without the above commits
  
  git checkout -b quickfix origin/master  # "upstream" is master on origin
  # fix, commit
  git push
  

  With push.default equal to upstream (or tracking), the push would go to origin’s master branch. When it is equal to current, the push would go to origin’s quickfix branch.

The matching setting will update bare’s master in your scenario once it has been established. To establish it, you could use git push origin master once.

However, the upstream setting (or maybe current) seems like it might be a better match for what you expect to happen, so you might want to try it:

# try it once (in Git 1.7.2 and later)
git -c push.default=upstream push

# configure it for only this repository
git config push.default upstream

# configure it for all repositories that do not override it themselves
git config --global push.default upstream

(Again, if you are still using a Git before 1.7.4.2, you will need to use tracking instead of upstream).

If your markup is bound to a controller, directive or anything else with a $scope:

console.log($scope.movie);

There are many possibilities to solve this task.

1. RUN the batch file with full path

The easiest solution is running the batch file with full path.

"F:\- Big Packets -\kitterengine\Common\Template.bat"

Once end of batch file Template.bat is reached, there is no return to previous script in case of the command line above is within a *.bat or *.cmd file.

The current directory for the batch file Template.bat is the current directory of the current process. In case of Template.bat requires that the directory of this batch file is the current directory, the batch file Template.bat should contain after @echo off as second line the following command line:

cd /D "%~dp0"

Run in a command prompt window cd /? for getting displayed the help of this command explaining parameter /D ... change to specified directory also on a different drive.

Run in a command prompt window call /? for getting displayed the help of this command used also in 2., 4. and 5. solution and explaining also %~dp0 ... drive and path of argument 0 which is the name of the batch file.

2. CALL the batch file with full path

Another solution is calling the batch file with full path.

call "F:\- Big Packets -\kitterengine\Common\Template.bat"

The difference to first solution is that after end of batch file Template.bat is reached the batch processing continues in batch script containing this command line.

For the current directory read above.

3. Change directory and RUN batch file with one command line

There are 3 operators for running multiple commands on one command line: &, && and ||.
For details see answer on Single line with multiple commands using Windows batch file

I suggest for this task the && operator.

cd /D "F:\- Big Packets -\kitterengine\Common" && Template.bat

As on first solution there is no return to current script if this is a *.bat or *.cmd file and changing the directory and continuation of batch processing on Template.bat is successful.

4. Change directory and CALL batch file with one command line

This command line changes the directory and on success calls the batch file.

cd /D "F:\- Big Packets -\kitterengine\Common" && call Template.bat

The difference to third solution is the return to current batch script on exiting processing of Template.bat.

5. Change directory and CALL batch file with keeping current environment with one command line

The four solutions above change the current directory and it is unknown what Template.bat does regarding

1. current directory
2. environment variables
3. command extensions state
4. delayed expansion state

In case of it is important to keep the environment of current *.bat or *.cmd script unmodified by whatever Template.bat changes on environment for itself, it is advisable to use setlocal and endlocal.

Run in a command prompt window setlocal /? and endlocal /? for getting displayed the help of these two commands. And read answer on change directory command cd ..not working in batch file after npm install explaining more detailed what these two commands do.

setlocal & cd /D "F:\- Big Packets -\kitterengine\Common" & call Template.bat & endlocal

Now there is only & instead of && used as it is important here that after setlocal is executed the command endlocal is finally also executed.

ONE MORE NOTE

If batch file Template.bat contains the command exit without parameter /B and this command is really executed, the command process is always exited independent on calling hierarchy. So make sure Template.bat contains exit /B or goto :EOF instead of just exit if there is exit used at all in this batch file.

Background

Absolute: The browser will always interpret / as the root of the hostname. For example, if my site was http://google.com/ and I specified /css/images.css then it would search for that at http://google.com/css/images.css. If your project root was actually at /myproject/ it would not find the css file. Therefore, you need to determine where your project folder root is relative to the hostname, and specify that in your href notation.

Relative: If you want to reference something you know is in the same path on the url - that is, if it is in the same folder, for example http://mysite.com/myUrlPath/index.html and http://mysite.com/myUrlPath/css/style.css, and you know that it will always be this way, you can go against convention and specify a relative path by not putting a leading / in front of your path, for example, css/style.css.

Filesystem Notations: Additionally, you can use standard filesystem notations like ... If you do http://google.com/images/../images/../images/myImage.png it would be the same as http://google.com/images/myImage.png. If you want to reference something that is one directory up from your file, use ../myFile.css.

Your Specific Case

In your case, you have two options:

• <link rel="stylesheet" type="text/css" href="/ServletApp/css/styles.css"/>
• <link rel="stylesheet" type="text/css" href="css/styles.css"/>

The first will be more concrete and compatible if you move things around, however if you are planning to keep the file in the same location, and you are planning to remove the /ServletApp/ part of the URL, then the second solution is better.

It also might be that you haven't declared you Dependency Injected service, as a provider in the component that you injected it to. That was my case :)

You can use a utility function I've created for the purpose of running code in the page context and getting back the returned value.

This is done by serializing a function to a string and injecting it to the web page.

The utility is available here on GitHub.

Usage examples -

// Some code that exists only in the page context -
window.someProperty = 'property';
function someFunction(name = 'test') {
    return new Promise(res => setTimeout(()=>res('resolved ' + name), 1200));
}
/////////////////

// Content script examples -

await runInPageContext(() => someProperty); // returns 'property'

await runInPageContext(() => someFunction()); // returns 'resolved test'

await runInPageContext(async (name) => someFunction(name), 'with name' ); // 'resolved with name'

await runInPageContext(async (...args) => someFunction(...args), 'with spread operator and rest parameters' ); // returns 'resolved with spread operator and rest parameters'

await runInPageContext({
    func: (name) => someFunction(name),
    args: ['with params object'],
    doc: document,
    timeout: 10000
} ); // returns 'resolved with params object'

I run into this when click on a html , it is fixed by adding type = "button" attribute.

These are the main factors involved:

1. member variable (default OK)
2. static variable (default OK)
3. final member variable (not initialized, must set on constructor)
4. final static variable (not initialized, must set on a static block {})
5. local variable (not initialized)

Note 1: you must initialize final member variables on every implemented constructor!

Note 2: you must initialize final member variables inside the block of the constructor itself, not calling another method that initializes them. For instance, this is not valid:

private final int memberVar;

public Foo() {
    // Invalid initialization of a final member
    init();
}

private void init() {
    memberVar = 10;
}

Note 3: arrays are Objects in Java, even if they store primitives.

Note 4: when you initialize an array, all of its items are set to default, independently of being a member or a local array.

I am attaching a code example, presenting the aforementioned cases:

public class Foo {
    // Static and member variables are initialized to default values

    // Primitives
    private int a; // Default 0
    private static int b; // Default 0

    // Objects
    private Object c; // Default NULL
    private static Object d; // Default NULL

    // Arrays (note: they are objects too, even if they store primitives)
    private int[] e; // Default NULL
    private static int[] f; // Default NULL

    // What if declared as final?

    // Primitives
    private final int g; // Not initialized. MUST set in the constructor
    private final static int h; // Not initialized. MUST set in a static {}

    // Objects
    private final Object i; // Not initialized. MUST set in constructor
    private final static Object j; // Not initialized. MUST set in a static {}

    // Arrays
    private final int[] k; // Not initialized. MUST set in constructor
    private final static int[] l; // Not initialized. MUST set in a static {}

    // Initialize final statics
    static {
        h = 5;
        j = new Object();
        l = new int[5]; // Elements of l are initialized to 0
    }

    // Initialize final member variables
    public Foo() {
        g = 10;
        i = new Object();
        k = new int[10]; // Elements of k are initialized to 0
    }

    // A second example constructor
    // You have to initialize final member variables to every constructor!
    public Foo(boolean aBoolean) {
        g = 15;
        i = new Object();
        k = new int[15]; // Elements of k are initialized to 0
    }

    public static void main(String[] args) {
        // Local variables are not initialized
        int m; // Not initialized
        Object n; // Not initialized
        int[] o; // Not initialized

        // We must initialize them before use
        m = 20;
        n = new Object();
        o = new int[20]; // Elements of o are initialized to 0
    }
}

I found a good Blog post about the behaviour of Hibernate in this kind of object mappings: http://blog.eyallupu.com/2010/06/hibernate-exception-simultaneously.html

The choice command is not available everywhere. With newer Windows versions, the set command has the /p option you can get user input

SET /P variable=[promptString]

see set /? for more info

I also recommend using Joda as mentioned before.

Solving your problem using standard Java Date objects only can be done as follows:

    // **** YOUR CODE **** BEGIN ****
    long ts = System.currentTimeMillis();
    Date localTime = new Date(ts);
    String format = "yyyy/MM/dd HH:mm:ss";
    SimpleDateFormat sdf = new SimpleDateFormat(format);

    // Convert Local Time to UTC (Works Fine)
    sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
    Date gmtTime = new Date(sdf.format(localTime));
    System.out.println("Local:" + localTime.toString() + "," + localTime.getTime() + " --> UTC time:"
            + gmtTime.toString() + "," + gmtTime.getTime());

    // **** YOUR CODE **** END ****

    // Convert UTC to Local Time
    Date fromGmt = new Date(gmtTime.getTime() + TimeZone.getDefault().getOffset(localTime.getTime()));
    System.out.println("UTC time:" + gmtTime.toString() + "," + gmtTime.getTime() + " --> Local:"
            + fromGmt.toString() + "-" + fromGmt.getTime());

Output:

Local:Tue Oct 15 12:19:40 CEST 2013,1381832380522 --> UTC time:Tue Oct 15 10:19:40 CEST 2013,1381825180000
UTC time:Tue Oct 15 10:19:40 CEST 2013,1381825180000 --> Local:Tue Oct 15 12:19:40 CEST 2013-1381832380000

Two options:

for (let item in MotifIntervention) {
    if (isNaN(Number(item))) {
        console.log(item);
    }
}

Or

Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));

(code in playground)

Edit

String enums look different than regular ones, for example:

enum MyEnum {
    A = "a",
    B = "b",
    C = "c"
}

Compiles into:

var MyEnum;
(function (MyEnum) {
    MyEnum["A"] = "a";
    MyEnum["B"] = "b";
    MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));

Which just gives you this object:

{
    A: "a",
    B: "b",
    C: "c"
}

You can get all the keys (["A", "B", "C"]) like this:

Object.keys(MyEnum);

And the values (["a", "b", "c"]):

Object.keys(MyEnum).map(key => MyEnum[key])

Or using Object.values():

Object.values(MyEnum)

The reason MyModel::all()->delete() doesn't work is because all() actually fires off the query and returns a collection of Eloquent objects.

You can make use of the truncate method, this works for Laravel 4 and 5:

MyModel::truncate();

That drops all rows from the table without logging individual row deletions.

You can also do it by checking if View's indexOfView method if indexOfView method returns -1 then we can use.

ViewGroup's detachViewFromParent(v); followed by ViewGroup's removeDetachedView(v, true/false);

You can use meta characters like * (http://api.jquery.com/category/selectors/). So I think you just can use $('#player_*').

In your case you could also try the "Attribute starts with" selector: http://api.jquery.com/attribute-starts-with-selector/: $('div[id^="player_"]')

You need httpclient.jar and httpcore.jar. You can download them from here.

http://archive.apache.org/dist/httpcomponents/httpclient/binary/

According to Swift 4 Documentation, String values can be added together (or concatenated) with the addition operator (+) to create a new String value:

let string1 = "hello"
let string2 = " there"
var welcome = string1 + string2
// welcome now equals "hello there"

You can also append a String value to an existing String variable with the addition assignment operator (+=):

var instruction = "look over"
instruction += string2
// instruction now equals "look over there"

You can append a Character value to a String variable with the String type’s append() method:

let exclamationMark: Character = "!"
welcome.append(exclamationMark)
// welcome now equals "hello there!"

Found FTav's answer the most useful as it is very customizable, but his xml2js function has some flaws. For instance, if children elements has equal tagnames they all will be stored in a single object, this means that the order of elements will not be preserved. In some cases we really want to preserve order, so we better store every element's data in a separate object:

function xml2js($xmlnode) {
    $jsnode = array();
    $nodename = $xmlnode->getName();
    $current_object = array();

    if (count($xmlnode->attributes()) > 0) {
        foreach($xmlnode->attributes() as $key => $value) {
            $current_object[$key] = (string)$value;
        }
    }

    $textcontent = trim((string)$xmlnode);
    if (strlen($textcontent) > 0) {
        $current_object["content"] = $textcontent;
    }

    if (count($xmlnode->children()) > 0) {
        $current_object['children'] = array();
        foreach ($xmlnode->children() as $childxmlnode) {
            $childname = $childxmlnode->getName();
            array_push($current_object['children'], xml2js($childxmlnode, true));
        }
    }

    $jsnode[ $nodename ] = $current_object;
    return $jsnode;
}

Here is how it works. Initial xml structure:

<some-tag some-attribute="value of some attribute">
  <another-tag>With text</another-tag>
  <surprise></surprise>
  <another-tag>The last one</another-tag>
</some-tag>

Result JSON:

{
    "some-tag": {
        "some-attribute": "value of some attribute",
        "children": [
            {
                "another-tag": {
                    "content": "With text"
                }
            },
            {

            },
            {

                    "content": "The last one"
                }
            }
        ]
    }
}

One difference is that interfaces create a new name that is used everywhere. Type aliases don’t create a new name — for instance, error messages won’t use the alias name.

powershell -Command "Remove-Item -LiteralPath 'folder' -Force -Recurse"

Note that in more cases del and rmdir wil leave you with leftover files, where Powershell manages to delete the files.

#include<iostream>
#include<ctime>

int main()
{
    std::time_t t = std::time(0);  // t is an integer type
    std::cout << t << " seconds since 01-Jan-1970\n";
    return 0;
}

Do I really have to first convert it into an array of arrays of key-value pairs?

No, an iterator of key-value pair arrays is enough. You can use the following to avoid creating the intermediate array:

function* entries(obj) {
    for (let key in obj)
        yield [key, obj[key]];
}

const map = new Map(entries({foo: 'bar'}));
map.get('foo'); // 'bar'

Assuming your example text is representative of all the text, one line would consume about 75 bytes on my machine:

In [3]: sys.getsizeof('usedfor zipper fasten_coat')
Out[3]: 75

Doing some rough math:

75 bytes * 8,000,000 lines / 1024 / 1024 = ~572 MB

So roughly 572 meg to store the strings alone for one of these files. Once you start adding in additional, similarly structured and sized files, you'll quickly approach your virtual address space limits, as mentioned in @ShadowRanger's answer.

If upgrading your python isn't feasible for you, or if it only kicks the can down the road (you have finite physical memory after all), you really have two options: write your results to temporary files in-between loading in and reading the input files, or write your results to a database. Since you need to further post-process the strings after aggregating them, writing to a database would be the superior approach.

After doing that don't forget to change your href in, <a href="{the chosen redirected name}"> home</a>

Example:

.htaccess file

RewriteEngine On

RewriteRule ^about/$ /about.php

PHP file:

<a href="about/"> about</a>

In version 0.24.+ pandas has gained the ability to hold integer dtypes with missing values.

Nullable Integer Data Type.

Pandas can represent integer data with possibly missing values using arrays.IntegerArray. This is an extension types implemented within pandas. It is not the default dtype for integers, and will not be inferred; you must explicitly pass the dtype into array() or Series:

arr = pd.array([1, 2, np.nan], dtype=pd.Int64Dtype())
pd.Series(arr)

0      1
1      2
2    NaN
dtype: Int64

For convert column to nullable integers use:

df['myCol'] = df['myCol'].astype('Int64')

CSS 3 introduces the background-size property, but support is not universal.

Having the browser resize the image is inefficient though, the large image still has to be downloaded. You should resize it server side (caching the result) and use that instead. It will use less bandwidth and work in more browsers.

As is, you must delete the row out of the advertisers table before you can delete the row in the jobs table that it references. This:

ALTER TABLE `advertisers`
  ADD CONSTRAINT `advertisers_ibfk_1` FOREIGN KEY (`advertiser_id`) 
      REFERENCES `jobs` (`advertiser_id`);

...is actually the opposite to what it should be. As it is, it means that you'd have to have a record in the jobs table before the advertisers. So you need to use:

ALTER TABLE `jobs`
  ADD CONSTRAINT `advertisers_ibfk_1` FOREIGN KEY (`advertiser_id`) 
      REFERENCES `advertisers` (`advertiser_id`);

Once you correct the foreign key relationship, your delete statement will work.

I was thinking about the horrible times I've spent in Numerical Analysis course.

And then I remember, there was this function circling around the 'net from the Quake Source code:

float Q_rsqrt( float number )
{
  long i;
  float x2, y;
  const float threehalfs = 1.5F;

  x2 = number * 0.5F;
  y  = number;
  i  = * ( long * ) &y;  // evil floating point bit level hacking
  i  = 0x5f3759df - ( i >> 1 ); // wtf?
  y  = * ( float * ) &i;
  y  = y * ( threehalfs - ( x2 * y * y ) ); // 1st iteration
  // y  = y * ( threehalfs - ( x2 * y * y ) ); // 2nd iteration, this can be removed

  #ifndef Q3_VM
  #ifdef __linux__
    assert( !isnan(y) ); // bk010122 - FPE?
  #endif
  #endif
  return y;
}

Which basically calculates a square root, using Newton's approximation function (cant remember the exact name).

It should be usable and might even be faster, it's from one of the phenomenal id software's game!

It's written in C++ but it should not be too hard to reuse the same technique in Java once you get the idea:

I originally found it at: http://www.codemaestro.com/reviews/9

Newton's method explained at wikipedia: http://en.wikipedia.org/wiki/Newton%27s_method

You can follow the link for more explanation of how it works, but if you don't care much, then this is roughly what I remember from reading the blog and from taking the Numerical Analysis course:

• the * (long*) &y is basically a fast convert-to-long function so integer operations can be applied on the raw bytes.
• the 0x5f3759df - (i >> 1); line is a pre-calculated seed value for the approximation function.
• the * (float*) &i converts the value back to floating point.
• the y = y * ( threehalfs - ( x2 * y * y ) ) line bascially iterates the value over the function again.

The approximation function gives more precise values the more you iterate the function over the result. In Quake's case, one iteration is "good enough", but if it wasn't for you... then you could add as much iteration as you need.

This should be faster because it reduces the number of division operations done in naive square rooting down to a simple divide by 2 (actually a * 0.5F multiply operation) and replace it with a few fixed number of multiplication operations instead.

The previous version, xlrd 1.2.0, may appear to work, but it could also expose you to potential security vulnerabilities. With that warning out of the way, if you still want to give it a go, type the following command:

pip install xlrd==1.2.0

$('#test').prop('checked', true);

Note only in jQuery 1.6+

Try looking into the following CSS:

word-wrap:break-word;

Web browsers should not break-up "words" by default so what you are experiencing is normal behaviour of a browser. However you can override this with the word-wrap CSS directive.

You would need to set a width on the overall table then a width on the columns. "width:100%;" should also be OK depending on your requirements.

Using word-wrap may not be what you want however it is useful for showing all of the data without deforming the layout.

Maybe the answer is this:

on the API >= 23 devices, if you install app (the app is not system app), you should check the storage permission in "Setting - applications", there is permission list for every app, you should check it on! try

The Github application for Windows shows all remote branches of a repository. If you have deleted the branch locally with $ git branch -d [branch_name], the remote branch still exists in your Github repository and will appear regardless in the Windows Github application.

If you want to delete the branch completely (remotely as well), use the above command in combination with $ git push origin :[name_of_your_new_branch]. Warning: this command erases all existing branches and may cause loss of code. Be careful, I do not think this is what you are trying to do.

However every time you delete the local branch changes, the remote branch will still appear in the application. If you do not want to keep making changes, just ignore it and do not click, otherwise you may clone the repository. If you had any more questions, please let me know.

You are trying to read the set value before Angular is done assigning.

Demo:

var testController = function ($scope, $timeout) {
    console.log('test');
    $timeout(function(){
        console.log($scope.testInput);
    },1000);
}

Ideally you should use $watch as suggested by @Beterraba to get rid of the timer:

var testController = function ($scope) {
    console.log('test');
    $scope.$watch("testInput", function(){
        console.log($scope.testInput);
    });
}

Your nav div is actually centered correctly. But the ul inside is not. Give the ul a specific width and center that as well.

Select last_name, round (sysdate-hire_date)/7,0) as tuner 
  from employees
  Where department_id = 90 
  order by last_name;

Don't you need something to compare and then retrieve the milliseconds?

For instance:

let enteredDate = $("#txt-date").val(); // get the date entered in the input
let expires = moment.utc(enteredDate); // convert it into UTC

With that you have the expiring date in UTC. Now you can get the "right-now" date in UTC and compare:

var rightNowUTC = moment.utc(); // get this moment in UTC based on browser
let duration = moment.duration(rightNowUTC.diff(expires)); // get the diff
let remainingTimeInMls = duration.asMilliseconds();

I can attest to the fact that -webkit-transform: translate3d(0, 0, 0); will mess with the new position: -webkit-sticky; property. With a left drawer navigation pattern that I was working on, the hardware acceleration I wanted with the transform property was messing with the fixed positioning of my top nav bar. I turned off the transform and the positioning worked fine.

Luckily, I seem to have had hardware acceleration on already, because I had -webkit-font-smoothing: antialiased on the html element. I was testing this behavior in iOS7 and Android.

For some Distributions, Cauchy I think, I have found that trapz will overestimate the area, and so the pdf will change depending on the number of bins you select. In which case I do

[N,h]=hist(q_f./theta,30000); % there Is a large range but most of the bins will be empty
plot(h,N/(sum(N)*mean(diff(h))),'+r')

Convert with JavaScript using .toLowerCase() and capitalize would do the rest.

In python3.6 I tried python3 -m venv myenv, as per the documentation, but it was taking so long. So the very simple and quick command is python -m venv yourenv It worked for me on python3.6.

System32 is where Windows historically placed all 32bit DLLs, and System was for the 16bit DLLs. When microsoft created the 64 bit OS, everyone I know of expected the files to reside under System64, but Microsoft decided it made more sense to put 64bit files under System32. The only reasoning I have been able to find, is that they wanted everything that was 32bit to work in a 64bit Windows w/o having to change anything in the programs -- just recompile, and it's done. The way they solved this, so that 32bit applications could still run, was to create a 32bit windows subsystem called Windows32 On Windows64. As such, the acronym SysWOW64 was created for the System directory of the 32bit subsystem. The Sys is short for System, and WOW64 is short for Windows32OnWindows64.
Since windows 16 is already segregated from Windows 32, there was no need for a Windows 16 On Windows 64 equivalence. Within the 32bit subsystem, when a program goes to use files from the system32 directory, they actually get the files from the SysWOW64 directory. But the process is flawed.

It's a horrible design. And in my experience, I had to do a lot more changes for writing 64bit applications, that simply changing the System32 directory to read System64 would have been a very small change, and one that pre-compiler directives are intended to handle.

This works:

function getBreakText($t) {
    return strtr($t, array('\\r\\n' => '<br>', '\\r' => '<br>', '\\n' => '<br>'));
}

I done it right now and asked myself, is it correct? Because I've never found a cleanest solution before than mine:

You just need to split the string versions ("1.0.0") like this example:

userVersion.split("\\.")

Then you will have: {"1", "0", "0"}

Now, using the method that I done:

isUpdateAvailable(userVersion.split("\\."), latestVersionSplit.split("\\."));

Method:

/**
 * Compare two versions
 *
 * @param userVersionSplit   - User string array with major, minor and patch version from user (exemple: {"5", "2", "70"})
 * @param latestVersionSplit - Latest string array with major, minor and patch version from api (example: {"5", "2", "71"})
 * @return true if user version is smaller than latest version
 */
public static boolean isUpdateAvailable(String[] userVersionSplit, String[] latestVersionSplit) {

    int majorUserVersion = Integer.parseInt(userVersionSplit[0]);
    int minorUserVersion = Integer.parseInt(userVersionSplit[1]);
    int patchUserVersion = Integer.parseInt(userVersionSplit[2]);

    int majorLatestVersion = Integer.parseInt(latestVersionSplit[0]);
    int minorLatestVersion = Integer.parseInt(latestVersionSplit[1]);
    int patchLatestVersion = Integer.parseInt(latestVersionSplit[2]);

    if (majorUserVersion <= majorLatestVersion) {
        if (majorUserVersion < majorLatestVersion) {
            return true;
        } else {
            if (minorUserVersion <= minorLatestVersion) {
                if (minorUserVersion < minorLatestVersion) {
                    return true;
                } else {
                    return patchUserVersion < patchLatestVersion;
                }
            }
        }
    }

    return false;
}

Waiting for any feedback :)

Except first answer form Bathsheba, except MSDN information for:

.Value
.Value2
.Text

you could analyse these tables for better understanding of differences between analysed properties.

"Connection reset by peer" is the TCP/IP equivalent of slamming the phone back on the hook. It's more polite than merely not replying, leaving one hanging. But it's not the FIN-ACK expected of the truly polite TCP/IP converseur. (From other SO answer)

So you can't do anything about it, it is the issue of the server.

But you could use try .. except block to handle that exception:

from socket import error as SocketError
import errno

try:
    response = urllib2.urlopen(request).read()
except SocketError as e:
    if e.errno != errno.ECONNRESET:
        raise # Not error we are looking for
    pass # Handle error here.

Easiest way to export Excel to Html table

$file_name ="file_name.xls";
$excel_file="Your Html Table Code";
header("Content-type: application/vnd.ms-excel");
header("Content-Disposition: attachment; filename=$file_name");
echo $excel_file;

Although overloading paradigm is not fully supported by PHP the same (or very similar) effect can be achieved with default parameter(s) (as somebody mentioned before).

If you define your function like this:

function f($p=0)
{
  if($p)
  {
    //implement functionality #1 here
  }
  else
  {
    //implement functionality #2 here
  }
}

When you call this function like:

f();

you'll get one functionality (#1), but if you call it with parameter like:

f(1);

you'll get another functionality (#2). That's the effect of overloading - different functionality depending on function's input parameter(s).

I know, somebody will ask now what functionality one will get if he/she calls this function as f(0).

Paul's solution above did what I was hoping it would.

$ git diff HEAD^1

Also, it's useful to add aliases like hobs mentioned, if you put the following in the [alias] section of your ~/.gitconfig file then you can use short-hand to view diff between head and previous.

[alias]
    diff-last = diff HEAD^1

Then running $ git diff-last will get you your result. Note that this will also include any changes you've not yet committed as well as the diff between commits. If you want to ignore changes you've not yet committed, then you can use diff to compare the HEAD with it's parent directly:

$ git diff HEAD^1 HEAD

One lesson from my experience:

offset floor(random() * N) limit 1 is not faster than order by random() limit 1.

I thought the offset approach would be faster because it should save the time of sorting in Postgres. Turns out it wasn't.

I tried to update the user, and it worked. See the command below.

USE ComparisonData// databaseName
EXEC  sp_change_users_login @Action='update_one', @UserNamePattern='ftool',@LoginName='ftool';

Just replace user('ftool') accordingly.

This one does well its scrolling job. It's very easy to understand, just really few lines of code, well written and totally readable.

Be sure to have both objects created in controller: @post and @comment for the post, eg:

@post = Post.find params[:post_id]
@comment = Comment.new(:post=>@post)

Then in view:

<%= form_for([@post, @comment]) do |f| %>

Be sure to explicitly define the array in the form_for, not just comma separated like you have above.

You'd have to use WebSockets (or some similar protocol module e.g. as supported by the Flash plugin) because a normal browser application simply can't open a pure TCP socket.

The Socket.IO module available for node.js can help a lot, but note that it is not a pure WebSocket module in its own right.

It's actually a more generic communications module that can run on top of various other network protocols, including WebSockets, and Flash sockets.

Hence if you want to use Socket.IO on the server end you must also use their client code and objects. You can't easily make raw WebSocket connections to a socket.io server as you'd have to emulate their message protocol.

I think that the best solution for drawing text in OpenGL is texture fonts, I work with them for a long time. They are flexible, fast and nice looking (with some rear exceptions). I use special program for converting font files (.ttf for example) to texture, which is saved to file of some internal "font" format (I've developed format and program based on http://content.gpwiki.org/index.php/OpenGL:Tutorials:Font_System though my version went rather far from the original supporting Unicode and so on). When starting the main app, fonts are loaded from this "internal" format. Look link above for more information.

With such approach the main app doesn't use any special libraries like FreeType, which is undesirable for me also. Text is being drawn using standard OpenGL functions.

Try this- Close the project then open it. It links with svn automatically,if project was checked out from valid svn path.

Use this:

plt.figure(figsize=(width,height))

The width and height are in inches.
If not provided, defaults to rcParams["figure.figsize"] = [6.4, 4.8]. See more here.

1. Create an XML file that represents the button states

Create an xml into drawable called 'button.xml' to name the button states:

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_enabled="false"
        android:drawable="@drawable/button_disabled" />
    <item
        android:state_pressed="true"
        android:state_enabled="true"
        android:drawable="@drawable/button_pressed" />
    <item
        android:state_focused="true"
        android:state_enabled="true"
        android:drawable="@drawable/button_focused" />
    <item
        android:state_enabled="true"
        android:drawable="@drawable/button_enabled" />
</selector>

2. Create an XML file that represents each button state

Create one xml file for each of the four button states. All of them should be under drawables folder. Let's follow the names set in the button.xml file.

button_enabled.xml:

<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <gradient
        android:startColor="#00CCFF"
        android:centerColor="#0000CC"
        android:endColor="#00CCFF"
        android:angle="90"/>
    <padding android:left="7dp"
        android:top="7dp"
        android:right="7dp"
        android:bottom="7dp" />
    <stroke
        android:width="2dip"
        android:color="#FFFFFF" />
    <corners android:radius= "8dp" />
</shape>

button_focused.xml:

<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <gradient
        android:startColor="#F7D358"
        android:centerColor="#DF7401"
        android:endColor="#F7D358"
        android:angle="90"/>
    <padding android:left="7dp"
        android:top="7dp"
        android:right="7dp"
        android:bottom="7dp" />
    <stroke
        android:width="2dip"
        android:color="#FFFFFF" />
    <corners android:radius= "8dp" />
</shape>

button_pressed.xml:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <gradient
        android:startColor="#0000CC"
        android:centerColor="#00CCFF"
        android:endColor="#0000CC"
        android:angle="90"/>
    <padding android:left="7dp"
        android:top="7dp"
        android:right="7dp"
        android:bottom="7dp" />
    <stroke
        android:width="2dip"
        android:color="#FFFFFF" />
    <corners android:radius= "8dp" />
</shape>

button_disabled.xml:

<?xml version="1.0" encoding="utf-8"?>

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <gradient
        android:startColor="#F2F2F2"
        android:centerColor="#A4A4A4"
        android:endColor="#F2F2F2"
        android:angle="90"/>
    <padding android:left="7dp"
        android:top="7dp"
        android:right="7dp"
        android:bottom="7dp" />
    <stroke
        android:width="2dip"
        android:color="#FFFFFF" />
    <corners android:radius= "8dp" />
</shape>

3. Create an XML file that represents the button style

Once you have created the files mentioned above, it's time to create your application button style. Now, you need to create a new XML file, called styles.xml (if you don't have it yet) where you can include more custom styles, into de values directory.

This file will contain the new button style of your application. You need to set your new button style features in it. Note that one of those features, the background of your new style, should be set with a reference to the button (button.xml) drawable that was created in the first step. To refer to the new button style we use the name attribute.

The example below show the content of the styles.xml file:

<resources>
    <style name="button" parent="@android:style/Widget.Button">
        <item name="android:gravity">center_vertical|center_horizontal</item>
        <item name="android:textColor">#FFFFFFFF</item>
        <item name="android:shadowColor">#FF000000</item>
        <item name="android:shadowDx">0</item>
        <item name="android:shadowDy">-1</item>
        <item name="android:shadowRadius">0.2</item>
        <item name="android:textSize">16dip</item>
        <item name="android:textStyle">bold</item>
        <item name="android:background">@drawable/button</item>
        <item name="android:focusable">true</item>
        <item name="android:clickable">true</item>
    </style>
</resources>

4. Create an XML with your own custom application theme

Finally, you need to override the default Android button style. For that, you need to create a new XML file, called themes.xml (if you don't have it yet), into the values directory and override the default Android button style.

The example below show the content of the themes.xml:

<resources>
    <style name="YourApplicationTheme" parent="android:style/Theme.NoTitleBar">
        <item name="android:buttonStyle">@style/button</item>
    </style>
</resources>

Hope you guys can have the same luck as I had with this, when I was looking for custom buttons. Enjoy.

Just for completeness:

I really like the --format option, but at first I wasn't aware of it so I used a simple Python one-liner to get the same result:

docker inspect <CONTAINER> |python -c 'import json,sys;obj=json.load(sys.stdin);print obj[0]["NetworkSettings"]["IPAddress"]'

With native JavaScript:

newelement = element.cloneNode(bool)

where the Boolean indicates whether to clone child nodes or not.

I found the information in this conversation so helpful that I just wanted to add how I figured it out by using the timestamp from my MySQL database and a little PHP

The output was: 2017-03-03T08:22:36+01:00

I hope this will solve the issue.

There is a plugin for jQuery called inview which adds a new "inview" event.

Here is some code for a jQuery plugin that doesn't use events:

$.extend($.expr[':'],{
    inView: function(a) {
        var st = (document.documentElement.scrollTop || document.body.scrollTop),
            ot = $(a).offset().top,
            wh = (window.innerHeight && window.innerHeight < $(window).height()) ? window.innerHeight : $(window).height();
        return ot > st && ($(a).height() + ot) < (st + wh);
    }
});

(function( $ ) {
    $.fn.inView = function() {
        var st = (document.documentElement.scrollTop || document.body.scrollTop),
        ot = $(this).offset().top,
        wh = (window.innerHeight && window.innerHeight < $(window).height()) ? window.innerHeight : $(window).height();

        return ot > st && ($(this).height() + ot) < (st + wh);
    };
})( jQuery );

I found this in a comment here ( http://remysharp.com/2009/01/26/element-in-view-event-plugin/ ) by a bloke called James

Use the display property in CSS:

<body> 
    <div id="invisible" style="display:none;">Invisible DIV</div>  
    <div>Another DIV 
        <button onclick="document.getElementById('invisible').style.display='block'">
            Button
        </button>  
    </div>  
</body>

When the the display of the first div is set back to block it will appear and shift the second div down.

Solved using JavaScript + jQuery! I just need similar solution to my project but current solution with HTML and CSS is not ok for me because there is issue with column height + I need more then one column to be fixed. So I create simple javascript solution using jQuery

You can try it here https://jsfiddle.net/kindrosker/ffwqvntj/

All you need is setup home many columsn will be fixed in data-count-fixed-columns parameter

<table class="table" data-count-fixed-columns="2" cellpadding="0" cellspacing="0">

and run js function

app_handle_listing_horisontal_scroll($('#table-listing'))

Try to put all your <script ...></script> tags before the </body> tag. Perhaps the js is trying to access an object of the DOM before it's built up.

If the above does not work then try the following. It solved the problem for me even when the owner was well defined for the database.

SQL Server 2008 replication failing with: process could not execute 'sp_replcmds'

const obj = {
   ...(condition) && {someprop: propvalue},
   ...otherprops
}

Live Demo:

const obj = {_x000D_
  ...(true) && {someprop: 42},_x000D_
  ...(false) && {nonprop: "foo"},_x000D_
  ...({}) && {tricky: "hello"},_x000D_
}_x000D_
_x000D_
console.log(obj);

This will do what you want:

INSERT INTO table2 (st_id,uid,changed,status,assign_status)
SELECT st_id,from_uid,now(),'Pending','Assigned'
FROM table1

If you want to include all rows from table1. Otherwise you can add a WHERE statement to the end if you want to add only a subset of table1.

I hope this helps.

This was previously asked on R-Help, so that's worth reviewing.

One suggestion there was to use readChar() and then do string manipulation on the result with strsplit() and substr(). You can see the logic involved in readChar is much less than read.table.

I don't know if memory is an issue here, but you might also want to take a look at the HadoopStreaming package. This uses Hadoop, which is a MapReduce framework designed for dealing with large data sets. For this, you would use the hsTableReader function. This is an example (but it has a learning curve to learn Hadoop):

str <- "key1\t3.9\nkey1\t8.9\nkey1\t1.2\nkey1\t3.9\nkey1\t8.9\nkey1\t1.2\nkey2\t9.9\nkey2\"
cat(str)
cols = list(key='',val=0)
con <- textConnection(str, open = "r")
hsTableReader(con,cols,chunkSize=6,FUN=print,ignoreKey=TRUE)
close(con)

The basic idea here is to break the data import into chunks. You could even go so far as to use one of the parallel frameworks (e.g. snow) and run the data import in parallel by segmenting the file, but most likely for large data sets that won't help since you will run into memory constraints, which is why map-reduce is a better approach.

Create a TXT file on your desktop named "xls2csv.vbs" and paste the code:

Dim vExcel
Dim vCSV
Set vExcel = CreateObject("Excel.Application")
Set vCSV = vExcel.Workbooks.Open(Wscript.Arguments.Item(0))
vCSV.SaveAs WScript.Arguments.Item(0) & ".csv", 6
vCSV.Close False
vExcel.Quit

Drag a XLS file to it (like "test.xls"). It will create a converted CSV file named "test.xls.csv". Then, rename it to "test.csv". Done.

You get this error if you have service A that depends on a static property / method of service B and the service B itself depends on service A trough dependency injection. So it's a kind of a circular dependency, although it isn't since the property / method is static. Probably a bug that occurs in combination with AOT.

My particular issue was caused because I was working with directories that involved symbolic links (shortcuts). Consequently, trying java -jar ../../myJar.jar didn't work because I wasn't where I thought I was.

Disregarding relative file paths fixed it right up.

You can do it using the module pattern. Just like:

var foo = function() {
  var that = {};

  that.a = 7;
  that.b = 6;

  that.c = function() {
    return that.a + that.b;
  }

  return that;
};
var fooObject = foo();
fooObject.c(); //13

With this pattern you can instantiate several foo objects according to your need.

One can avoid the AttributeError brought about by set_axis_labels() method by using the matplotlib.pyplot.xlabel and matplotlib.pyplot.ylabel.

matplotlib.pyplot.xlabel sets the x-axis label while the matplotlib.pyplot.ylabel sets the y-axis label of the current axis.

Solution code:

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

fake = pd.DataFrame({'cat': ['red', 'green', 'blue'], 'val': [1, 2, 3]})
fig = sns.barplot(x = 'val', y = 'cat', data = fake, color = 'black')
plt.xlabel("Colors")
plt.ylabel("Values")
plt.title("Colors vs Values") # You can comment this line out if you don't need title
plt.show(fig)

Output figure:

I did the following

1. Delete my db.sqlite3 database
2. python manage.py makemigrations
3. python manage.py migrate

It renewed the database and fixed the issues without affecting my project. Please note you might need to do python manage.py createsuperuser because it will affect all your objects being created.

There isn't really a way to edit files in-place. What you usually do when you can get away with it (i.e. if the files are not too big) is, you read the file into memory (File.read), perform your substitutions on the read string (String#gsub) and then write the changed string back to the file (File.open, File#write).

If the files are big enough for that to be unfeasible, what you need to do, is read the file in chunks (if the pattern you want to replace won't span multiple lines then one chunk usually means one line - you can use File.foreach to read a file line by line), and for each chunk perform the substitution on it and append it to a temporary file. When you're done iterating over the source file, you close it and use FileUtils.mv to overwrite it with the temporary file.

use float:left on the div and the link, or use a span.

Call onBackPressed after overriding it in your activity.

Since I only use admin interface in my app, I put this in the admin.py :

admin.site.site_header = 'My administration'

If you created imageview using xml file then follow the steps.

Solution 1:

Step 1: Create an XML file

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:background="#cc8181"
  >

  <ImageView
      android:id="@+id/image"
      android:layout_width="50dip"
      android:layout_height="fill_parent" 
      android:src="@drawable/icon"
      android:layout_marginLeft="3dip"
      android:scaleType="center"/>

</LinearLayout>

Step 2: create an Activity

ImageView img= (ImageView) findViewById(R.id.image);
img.setImageResource(R.drawable.my_image);

Solution 2:

If you created imageview from Java Class

ImageView img = new ImageView(this);
img.setImageResource(R.drawable.my_image);

May be you want this (oop in javascript)

function box(color)
{
    this.color=color;
}

var box1=new box('red');    
var box2=new box('white');

upstream in the github example is just the name they've chosen to refer to that repository. You may choose any that you like when using git remote add. Depending on what you select for this name, your git pull usage will change. For example, if you use:

git remote add upstream git://github.com/somename/original-project.git

then you would use this to pull changes:

git pull upstream master

But, if you choose origin for the name of the remote repo, your commands would be:

To name the remote repo in your local config: git remote add origin git://github.com/somename/original-project.git

And to pull: git pull origin master

As EJP said, it's a message shown because of a call to a non-https protocol. If you are sure it is HTTPS, check your bypass proxy settings, and in case add your webservice host url to the bypass proxy list

select * from person where DATE(dob) between '2011-01-01' and '2011-01-31'

Surprisingly such conversions are solutions to many problems in MySQL.

Using UITextViewDelegate is the easiest way:

func textViewDidChange(_ textView: UITextView) {
    textView.sizeToFit()
    textviewHeight.constant = textView.contentSize.height
}

Check your selector in your filename.component.ts

Using the tag in various html files I would say

<my-first-component></my-first-component>

Should be

<app-my-first-component></app-my-first-component>

Example

@Component({
  selector: 'app-my-first-component',
  templateUrl: './my-first-component.component.html',
  styleUrls: ['./my-first-component.component.scss']
})

.....

$("#testID #testID2").removeClass("test2").addClass("test3");

Because you have assigned an id to img too, you can simply do this too:

$("#testID2").removeClass("test2").addClass("test3");

And finally, you can do this too:

$("#testID img").removeClass("test2").addClass("test3");

While specifying spellcheck="false" in the < tag > will certainly disable that feature, it's handy to be able to toggle that functionality on and off as needed after the page has loaded. So here's a non-jQuery way to set the spellcheck attribute programmatically:

:

<textarea id="my-ta" spellcheck="whatever">abcd dcba</textarea>

:

function setSpellCheck( mode ) {
    var myTextArea = document.getElementById( "my-ta" )
        , myTextAreaValue = myTextArea.value
    ;
    myTextArea.value = '';
    myTextArea.setAttribute( "spellcheck", String( mode ) );
    myTextArea.value = myTextAreaValue;
    myTextArea.focus();
}

:

setSpellCheck( true );
setSpellCheck( 'false' );

The function argument may be either boolean or string.

No need to loop through the textarea contents, we just cut 'n paste what's there, and then set focus.

Tested in blink engines (Chrome(ium), Edge, etc.)

I believe the best way to do this is to use the LocalTimezone class defined in the datetime.tzinfo documentation (goto http://docs.python.org/library/datetime.html#tzinfo-objects and scroll down to the "Example tzinfo classes" section):

Assuming Local is an instance of LocalTimezone

t = datetime.datetime(2009, 7, 10, 18, 44, 59, 193982, tzinfo=utc)
local_t = t.astimezone(Local)

then str(local_t) gives:

'2009-07-11 04:44:59.193982+10:00'

which is what you want.

(Note: this may look weird to you because I'm in New South Wales, Australia which is 10 or 11 hours ahead of UTC)

1. 'sender' is called object which has some action perform on some control

2. 'event' its having some information about control which has some behavoiur and identity perform by some user.when action will generate by occuring for event add it keep within array is called event agrs

(from a in db.Assignments
     join b in db.Deliveryboys on a.AssignTo equals b.EmployeeId  

     //from d in eGroup.DefaultIfEmpty()
     join  c in  db.Deliveryboys on a.DeliverTo equals c.EmployeeId into eGroup2
     from e in eGroup2.DefaultIfEmpty()
     where (a.Collected == false)
     select new
     {
         OrderId = a.OrderId,
         DeliveryBoyID = a.AssignTo,
         AssignedBoyName = b.Name,
         Assigndate = a.Assigndate,
         Collected = a.Collected,
         CollectedDate = a.CollectedDate,
         CollectionBagNo = a.CollectionBagNo,
         DeliverTo = e == null ? "Null" : e.Name,
         DeliverDate = a.DeliverDate,
         DeliverBagNo = a.DeliverBagNo,
         Delivered = a.Delivered

     });

Try this in your code:

Calendar cal = Calendar.getInstance();              
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra("beginTime", cal.getTimeInMillis());
intent.putExtra("allDay", true);
intent.putExtra("rrule", "FREQ=YEARLY");
intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
intent.putExtra("title", "A Test Event from android app");
startActivity(intent);

The answer your question: the correct way to refer to a different sheet is by appropriately qualifying each Range you use. Please read this explanation and its conclusion, which I guess will give essential information.

The error you are getting is likely due to the sought-for value Sheet2!D2 not being found in the searched range Sheet1!A1:A65536. This may stem from two cases:

1. The value is actually not present (pointed out by chris nielsen).

2. You are searching the wrong Range. If the ActiveSheet is Sheet1, then using Range("D2") without qualifying it will be searching for Sheet1!D2, and it will throw the same error even if the sought-for value is present in the correct Range. Code accounting for this (and items below) follows:

   Sub srch()
       Dim ws1 As Worksheet, ws2 As Worksheet
       Dim srchres As Variant
   
       Set ws1 = Worksheets("Sheet1")
       Set ws2 = Worksheets("Sheet2")
   
       On Error Resume Next
       srchres = Application.WorksheetFunction.VLookup(ws2.Range("D2"), ws1.Range("A1:C65536"), 1, False)
       On Error GoTo 0
       If (IsEmpty(srchres)) Then
         ws2.Range("E2").Formula = CVErr(xlErrNA) ' Use whatever you want
       Else
         ws2.Range("E2").Value = srchres
       End If
   End Sub
   

I will point out a few additional notable points:

1. Catching the error as done by chris nielsen is a good practice, probably mandatory if using Application.WorksheetFunction.VLookup (although it will not suitably handle case 2 above).

2. This catching is actually performed by the function VLOOKUP as entered in a cell (and, if the sought-for value is not found, the result of the error is presented as #N/A in the result). That is why the first soluton by L42 does not need any extra error handling (it is taken care by =VLOOKUP...).

3. Using =VLOOKUP... is fundamentally different from Application.WorksheetFunction.VLookup: the first leaves a formula, whose result may change if the cells referenced change; the second writes a fixed value.

4. Both solutions by L42 qualify Ranges suitably.

5. You are searching the first column of the range, and returning the value in that same column. Other functions are available for that (although yours works fine).

For MAC:

1. Install Homebrew
2. brew install postgres
3. initdb /usr/local/var/postgres
4. /usr/local/Cellar/postgresql/<version>/bin/createuser -s postgres or /usr/local/opt/postgres/bin/createuser -s postgres which will just use the latest version.
5. start postgres server manually: pg_ctl -D /usr/local/var/postgres start

To start server at startup

• mkdir -p ~/Library/LaunchAgents
• ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
• launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

Now, it is set up, login using psql -U postgres -h localhost or use PgAdmin for GUI.

By default user postgres will not have any login password.

By default maven does not include any files from "src/main/java".

You have two possible way to that.

1. put all your resource files (different than java files) to "src/main/resources" - this is highly recommended

2. Add to your pom (resource plugin):

?

 <resources>
       <resource>
           <directory>src/main/resources</directory>
        </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
  </resources>

Systemd which now runs in the majority of distros

Step 1:

Find your user defined services mine was at /usr/lib/systemd/system/

Step 2:

Create a text file with your favorite text editor name it whatever_you_want.service

Step 3:

Put following Template to the file whatever_you_want.service

[Unit]
Description=webserver Daemon

[Service]
ExecStart=/usr/bin/java -jar /web/server.jar
User=user

[Install]
WantedBy=multi-user.target

Step 4:

Run your service
as super user

$ systemctl start whatever_you_want.service # starts the service
$ systemctl enable whatever_you_want.service # auto starts the service
$ systemctl disable whatever_you_want.service # stops autostart
$ systemctl stop whatever_you_want.service # stops the service
$ systemctl restart whatever_you_want.service # restarts the service

It might be caused by hibernate-enhance-maven-plugin. When I enabled enableLazyInitialization property this exception started on happening on my lazy collection. I'm using hibernate 5.2.17.Final.

Note this two hibernate issues:

• https://hibernate.atlassian.net/browse/HHH-10708
• https://hibernate.atlassian.net/browse/HHH-11459

In the very most simple case of no collisions

• with rebase: rebases your local commits ontop of remote HEAD and does not create a merge/merge commit
• without/normal: merges and creates a merge commit

See also:

man git-pull

More precisely, git pull runs git fetch with the given parameters and calls git merge to merge the retrieved branch heads into the current branch. With --rebase, it runs git rebase instead of git merge.

You should be able to access the local database by using the name localhost. There is also a way to determine the hostname of the computer you're running on, but it doesn't sound like you need that. As for the username, you can either (1) give permissions to the account that PHP runs under to access the database without a password, or (2) store the username and password that you need to connect with (hard-coded or stored in a config file), and pass those as arguments to mysql_connect. See http://php.net/manual/en/function.mysql-connect.php.

PHP File

<?php
$target_path  = "./Upload/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']).    " has been uploaded";
} else {
    echo "There was an error uploading the file, please try again!";
}

?>

You can also do it from command line much easily.

1. Open command line from the folder/package.

2. From command line run:

   javadoc YourClassName.java

3. To batch generate docs for multiple Class:

   javadoc *.java

For lists, use contains:

[1,2,3].contains(1) == true

Thank you guys for this thread! It helped me when I wanted to figure out an exe's file version. However, I needed to figure out the last bit myself of what is called Extended Properties.

If you open properties of an exe (or dll) file in Windows Explorer, you get a Version tab, and a view of Extended Properties of that file. I wanted to access one of those values.

The solution to this is the property indexer FolderItem.ExtendedProperty and if you drop all spaces in the property's name, you'll get the value. E.g. File Version goes FileVersion, and there you have it.

Hope this helps anyone else, just thought I'd add this info to this thread. Cheers!

use sys module

import sys
sys.exit()

1. Create a UNIQUE constraint on your subs_email column, if one does not already exist:

   ALTER TABLE subs ADD UNIQUE (subs_email)
   

2. Use INSERT ... ON DUPLICATE KEY UPDATE:

   INSERT INTO subs
     (subs_name, subs_email, subs_birthday)
   VALUES
     (?, ?, ?)
   ON DUPLICATE KEY UPDATE
     subs_name     = VALUES(subs_name),
     subs_birthday = VALUES(subs_birthday)
   

You can use the VALUES(col_name) function in the UPDATE clause to refer to column values from the INSERT portion of the INSERT ... ON DUPLICATE KEY UPDATE - dev.mysql.com

3. Note that I have used parameter placeholders in the place of string literals, as one really should be using parameterised statements to defend against SQL injection attacks.

This error occures when you try to refer to a null object instance. I can`t tell you what causes this error by your given information, but you can debug it easily in your IDE. I strongly recommend you that use exception handling to avoid unexpected program behavior.

System.IO.File.Create(@"C:\Temp.txt");

As others have pointed out, you should dispose of this object or wrap it in an empty using statement.

using (System.IO.File.Create(@"C:\Temp.txt"));

Start Powershell as administrator and run:

net start [MySQL-service-name]

Find the service name:

run 'services.msc', look for MySQL and click on properties

Please enable the following items in Windows 2012 R2

You can also do this in addition

import re
string='24234ww'
val = re.search('[a-zA-Z]+',string) 
val[0].isalpha() # returns True if the variable is an alphabet
print(val[0]) # this will print the first instance of the matching value

Also note that if variable val returns None. That means the search did not find a match

in visual studio 2012 in the web.config change the targetFramework=4.5 to targetFramework=4.0

Another solution is to use an SVG text node which is supported by most browsers.

<svg width="50" height="300">
    <text x="28" y="150" transform="rotate(-90, 28, 150)" style="text-anchor:middle; font-size:14px">This text is vertical</text>
</svg>

Demo: https://jsfiddle.net/bkymb5kr/

I use this or similar code to inject PHP messages into a fixed DIV positioned in front of other elements (z-index: 9999) just for convenience at the development stage.

Each PHP message passes into my 'custom_message()' function and is further conveyed into the innard of preformatted DIV created by echoed JS.

There can be as many as it gets, all put inside that fixed DIV, one under the other.

<style>
    #php_messages {
        position: fixed;
        left: 0;
        top: 0;
        z-index: 9999;
    }
    .php_message {
        background-color: #333;
        border: red solid 1px;
        color: white;
        font-family: "Courier New", Courier, monospace;
        margin: 1em;
        padding: 1em;
    }
</style>

<div id="php_messages"></div>

<?php
    function custom_message($output) {
        echo
            '
                <script>
                    var
                        el = document.createElement("DIV");
                    el.classList.add("php_message");
                    el.innerHTML = \''.$output.'\';
                    document.getElementById("php_messages").appendChild(el);
                </script>
            ';
    }
?>

This is similar to https://superuser.com/questions/477628/export-all-regular-expression-matches-in-textpad-or-notepad-as-a-list.

I hope you are trying to extract :
"Performance"
"Maintenance"
"System Stability"

Here is the way - Step 1/3: Open Search->Find->Replace Tab , select Regular Expression Radio button. Enter in Find what : (\"[a-zA-Z0-9\s]+\") and in Replace with : \n\1 and click Replace All buttton.

Step 2/3: After first step your keywords will be in next lines.(as shown in next image). Now go to Mark tab and enter the same regex expression in Find what: Field. Put check mark on Bookmark Line. Then Click Mark All.

Step 3/3 : Goto Search -> Bookmarks -> Remove unmarked lines.

So you have the final result as below

For me, you can't. But if that suits your needs, you could have speed and formatting by copying the whole range at once, instead of looping:

range("B2:B5002").Copy Destination:=Sheets("Output").Cells(startrow, 2)

And, by the way, you can build a custom range string, like Range("B2:B4, B6, B11:B18")

edit: if your source is "sparse", can't you just format the destination at once when the copy is finished ?

class vs static

class is used inside Reference Type(class):

• computed property
• method
• can be overridden by subclass

static is used inside Reference Type and Value Type(class, enum):

• computed property and stored property
• method
• cannot be changed by subclass

[Reference vs Value Type]

I love Richard Nienaber's answer, but as Chuu pointed out, it really doesn't tell how to accomplish what Richard is refering to as a solution. Therefore I have chosen to provide you with the way I ended up doing this, ending with the result Richard is talking about.

The solution

In this case I'm creating a greeting widget that needs to know which options it has to greet in. This may be an over-engineered solution to OPs question as I am also creating an container for possible future widgets.

First I set up my collection to handle the different greetings

public class GreetingWidgetCollection : System.Configuration.ConfigurationElementCollection
{
    public List<IGreeting> All { get { return this.Cast<IGreeting>().ToList(); } }

    public GreetingElement this[int index]
    {
        get
        {
            return base.BaseGet(index) as GreetingElement;
        }
        set
        {
            if (base.BaseGet(index) != null)
            {
                base.BaseRemoveAt(index);
            }
            this.BaseAdd(index, value);
        }
    }

    protected override ConfigurationElement CreateNewElement()
    {
        return new GreetingElement();
    }

    protected override object GetElementKey(ConfigurationElement element)
    {
        return ((GreetingElement)element).Greeting;
    }
}

Then we create the acutal greeting element and it's interface

(You can omit the interface, that's just the way I'm always doing it.)

public interface IGreeting
{
    string Greeting { get; set; }
}

public class GreetingElement : System.Configuration.ConfigurationElement, IGreeting
{
    [ConfigurationProperty("greeting", IsRequired = true)]
    public string Greeting
    {
        get { return (string)this["greeting"]; }
        set { this["greeting"] = value; }
    }
}

The greetingWidget property so our config understands the collection

We define our collection GreetingWidgetCollection as the ConfigurationProperty greetingWidget so that we can use "greetingWidget" as our container in the resulting XML.

public class Widgets : System.Configuration.ConfigurationSection
{
    public static Widgets Widget => ConfigurationManager.GetSection("widgets") as Widgets;

    [ConfigurationProperty("greetingWidget", IsRequired = true)]
    public GreetingWidgetCollection GreetingWidget
    {
        get { return (GreetingWidgetCollection) this["greetingWidget"]; }
        set { this["greetingWidget"] = value; }
    }
}

The resulting XML

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
   <widgets>
       <greetingWidget>
           <add greeting="Hej" />
           <add greeting="Goddag" />
           <add greeting="Hello" />
           ...
           <add greeting="Konnichiwa" />
           <add greeting="Namaskaar" />
       </greetingWidget>
    </widgets>
</configuration>

And you would call it like this

List<GreetingElement> greetings = Widgets.GreetingWidget.All;

Ran into a similar issue while restoring the database using SQL server management studio and it got stuck into restoring mode. After several hours of issue tracking, the following query worked for me. The following query restores the database from an existing backup to a previous state. I believe, the catch is the to have the .mdf and .log file in the same directory.

RESTORE DATABASE aqua_lc_availability
FROM DISK = 'path to .bak file'
WITH RECOVERY

I simplification for Science_Fiction's answer I think is to use the exclusive or function so you can just have:

if(checkbox1.checked ^ checkbox2.checked)
{
//do stuff
}

That is assuming you want to do the same thing for both situations.

string strData = "This is much easier"
int intDelimiterIndx = strData.IndexOf("is");
int intDelimiterLength = "is".Length;
str1 = strData.Substring(0, intDelimiterIndx);
str2 = strData.Substring(intDelimiterIndx + intDelimiterLength, strData.Length - (intDelimiterIndx + intDelimiterLength));

Microsoft Windows: Windows kernel forbids the use of characters in range 1-31 (i.e., 0x01-0x1F) and characters " * : < > ? \ |. Although NTFS allows each path component (directory or filename) to be 255 characters long and paths up to about 32767 characters long, the Windows kernel only supports paths up to 259 characters long. Additionally, Windows forbids the use of the MS-DOS device names AUX, CLOCK$, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, CON, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9, NUL and PRN, as well as these names with any extension (for example, AUX.txt), except when using Long UNC paths (ex. \.\C:\nul.txt or \?\D:\aux\con). (In fact, CLOCK$ may be used if an extension is provided.) These restrictions only apply to Windows - Linux, for example, allows use of " * : < > ? \ | even in NTFS.

Okay, redis is pretty user friendly but there are some gotchas.

Here are just some easy commands for working with redis on Ubuntu:

install:

sudo apt-get install redis-server

start with conf:

sudo redis-server <path to conf>
sudo redis-server config/redis.conf

stop with conf:

redis-ctl shutdown

(not sure how this shuts down the pid specified in the conf. Redis must save the path to the pid somewhere on boot)

log:

tail -f /var/log/redis/redis-server.log

Also, various example confs floating around online and on this site were beyond useless. The best, sure fire way to get a compatible conf is to copy-paste the one your installation is already using. You should be able to find it here:

/etc/redis/redis.conf

Then paste it at <path to conf>, tweak as needed and you're good to go.

This probably is not a good answer, but i just want to share my experience with this issue.

My app is globally use utc date with the format 'YYYY-MM-DD', while the datepicker plugin i use only accept js date, it's hard for me to consider both utc and js. So when i want to pass a 'YYYY-MM-DD' formatted date to my datepicker, i first convert it to 'MM/DD/YYYY' format using moment.js or whatever you like, and the date shows on datepicker is now correct. For your example

var d = new Date('2011-09-24'); // d will be 'Fri Sep 23 2011 20:00:00 GMT-0400 (EDT)' for my lacale
var d1 = new Date('09/24/2011'); // d1 will be 'Sat Sep 24 2011 00:00:00 GMT-0400 (EDT)' for my lacale

Apparently d1 is what i want. Hope this would be helpful for some people.

We need to specify the INITIAL_CONTEXT_FACTORY, PROVIDER_URL, USERNAME, PASSWORD etc. of JNDI to create an InitialContext.

In a standalone application, you can specify that as below

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, 
    "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://ldap.wiz.com:389");
env.put(Context.SECURITY_PRINCIPAL, "joeuser");
env.put(Context.SECURITY_CREDENTIALS, "joepassword");

Context ctx = new InitialContext(env);

But if you are running your code in a Java EE container, these values will be fetched by the container and used to create an InitialContext as below

System.getProperty(Context.PROVIDER_URL);

and

these values will be set while starting the container as JVM arguments. So if you are running the code in a container, the following will work

InitialContext ctx = new InitialContext();

From the jQuery documentation - http://api.jquery.com/jQuery.ajax/

contentType When sending data to the server, use this content type.

dataType 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

"text": A plain text string.

So you want contentType to be application/json and dataType to be text:

$.ajax({
    type : "POST",
    url : /v1/user,
    dataType : "text",
    contentType: "application/json",
    data : dataAttribute,
    success : function() {

    },
    error : function(error) {

    }
});

@DanielChapman gives a good explanation of serialVersionUID, but no solution. the solution is this: run the serialver program on all your old classes. put these serialVersionUID values in your current versions of the classes. as long as the current classes are serial compatible with the old versions, you should be fine. (note for future code: you should always have a serialVersionUID on all Serializable classes)

if the new versions are not serial compatible, then you need to do some magic with a custom readObject implementation (you would only need a custom writeObject if you were trying to write new class data which would be compatible with old code). generally speaking adding or removing class fields does not make a class serial incompatible. changing the type of existing fields usually will.

Of course, even if the new class is serial compatible, you may still want a custom readObject implementation. you may want this if you want to fill in any new fields which are missing from data saved from old versions of the class (e.g. you have a new List field which you want to initialize to an empty list when loading old class data).

If you want to do it using XAML set the property isReadOnly to true.

Check this: USING FOR LOOP

for a in range(5):
    x='A'
    val=chr(ord(x) + a)
    print(val)

This error can happen when, in IIS Manager, the ASP.NET MVC site is pointed to the wrong directory.

In my case, I inadvertently had the site pointed to the solution directory instead of the child project directory. That is, I had the site's Physical path set to

C:\dev\MySolution

instead of

C:\dev\MySolution\MyProject.

Specific steps to fix this:

1. Open IIS Manager (Start > Run > inetmgr);
2. In IIS Manager, in the left pane, expand Sites;
3. Under Sites, left-click the ASP.NET MVC website;
4. In the right pane, click Basic Settings...;
5. In the Edit Site dialog, change the Physical path to the project directory.
6. Click OK.

There's no way around it except to store it. Memory paging should reduce potential issues there.

I would suggest instead of using a global variable called 'xml', do something more like this:

var dataStore = (function(){
    var xml;

    $.ajax({
      type: "GET",
      url: "test.xml",
      dataType: "xml",
      success : function(data) {
                    xml = data;
                }
    });

    return {getXml : function()
    {
        if (xml) return xml;
        // else show some error that it isn't loaded yet;
    }};
})();

then access it with:

$(dataStore.getXml()).find('something').attr('somethingElse');

It's also worth noting that ActiveX controls only work in Windows, whereas Form Controls will work on both Windows and MacOS versions of Excel.

First make sure that you've installed the plugin, but it's likely that the workspace directory isn't properly set. Just check Pylint and edit the underlying settings.json file.

{
    "python.pythonPath": "/usr/local/bin/python3",
    "git.ignoreLimitWarning": true
}

The direct use of EDATE(Start_date, months) do the job of ADDDate. Example:

Consider A1 = 20/08/2012 and A2 = 3

=edate(A1; A2)

Would calculate 20/11/2012

PS: dd/mm/yyyy format in my example

Compile parses the regular expression and builds an in-memory representation. The overhead to compile is significant compared to a match. If you're using a pattern repeatedly it will gain some performance to cache the compiled pattern.

Please check it this:

This is working in chrome and all browser.

It would seem overkill but Spring Forms handles this elegantly. That is of course if you are already using Spring MVC and you want to take advantage of the Spring Forms feature.

// jsp form
    <form:select path="friendlyNumber" items="${friendlyNumberItems}" />

    // the command class
    public class NumberCmd {
      private String[] friendlyNumber;
    }

    // in your Spring MVC controller submit method
    @RequestMapping(method=RequestMethod.POST)
    public String manageOrders(@ModelAttribute("nbrCmd") NumberCmd nbrCmd){

       String[] selectedNumbers = nbrCmd.getFriendlyNumber();

    }

PAGEIOLATCH_SH wait type usually comes up as the result of fragmented or unoptimized index.

Often reasons for excessive PAGEIOLATCH_SH wait type are:

• I/O subsystem has a problem or is misconfigured
• Overloaded I/O subsystem by other processes that are producing the high I/O activity
• Bad index management
• Logical or physical drive misconception
• Network issues/latency
• Memory pressure
• Synchronous Mirroring and AlwaysOn AG

In order to try and resolve having high PAGEIOLATCH_SH wait type, you can check:

• SQL Server, queries and indexes, as very often this could be found as a root cause of the excessive PAGEIOLATCH_SH wait types
• For memory pressure before jumping into any I/O subsystem troubleshooting

Always keep in mind that in case of high safety Mirroring or synchronous-commit availability in AlwaysOn AG, increased/excessive PAGEIOLATCH_SH can be expected.

You can find more details about this topic in the article Handling excessive SQL Server PAGEIOLATCH_SH wait types

Just use the JSON.stringify method and pass it through as the "data" parameter for the $.ajax function, like follows:

$.ajax({
    type: "POST",
    url: "index.php",
    dataType: "json",
    data: JSON.stringify({ paramName: info }),
    success: function(msg){
        $('.answer').html(msg);
    }
});

You just need to make sure you include the JSON2.js file in your page...

I'm using MVC3/EntityFramework as back-end, the front-end consumes all of my project controllers via jquery, posting directly (using $.post) doesnt requires the data encription, when you pass params directly other than URL hardcoded. I already tested several chars i even sent an URL(this one http://www.ihackforfun.eu/index.php?title=update-on-url-crazy&more=1&c=1&tb=1&pb=1) as a parameter and had no issue at all even though encodeURIComponent works great when you pass all data in within the URL (hardcoded)

Hardcoded URL i.e.>

 var encodedName = encodeURIComponent(name);
 var url = "ControllerName/ActionName/" + encodedName + "/" + keyword + "/" + description + "/" + linkUrl + "/" + includeMetrics + "/" + typeTask + "/" + project + "/" + userCreated + "/" + userModified + "/" + status + "/" + parent;; // + name + "/" + keyword + "/" + description + "/" + linkUrl + "/" + includeMetrics + "/" + typeTask + "/" + project + "/" + userCreated + "/" + userModified + "/" + status + "/" + parent;

Otherwise dont use encodeURIComponent and instead try passing params in within the ajax post method

 var url = "ControllerName/ActionName/";   
 $.post(url,
        { name: nameVal, fkKeyword: keyword, description: descriptionVal, linkUrl: linkUrlVal, includeMetrics: includeMetricsVal, FKTypeTask: typeTask, FKProject: project, FKUserCreated: userCreated, FKUserModified: userModified, FKStatus: status, FKParent: parent },
 function (data) {.......});

Although this question was more specifically about IP addresses in Subject Alt. Names, the commands are similar (using DNS entries for a host name and IP entries for IP addresses).

To quote myself:

If you're using keytool, as of Java 7, keytool has an option to include a Subject Alternative Name (see the table in the documentation for -ext): you could use -ext san=dns:www.example.com or -ext san=ip:10.0.0.1

Note that you only need Java 7's keytool to use this command. Once you've prepared your keystore, it should work with previous versions of Java.

(The rest of this answer also mentions how to do this with OpenSSL, but it doesn't seem to be what you're using.)
