If you click Manage Hudson / Reload Configuration From Disk, Hudson will reload all the build history data.

If the data on disk is messed up, you'll need to go to your %HUDSON_HOME%\jobs\<projectname> directory and restore the build directories as they're supposed to be. Then reload config data.

If you're simply asking how to remove all build history, you can just delete the builds one by one via the UI if there are just a few, or go to the %HUDSON_HOME%\jobs\<projectname> directory and delete all the subdirectories there -- they correspond to the builds. Afterwards restart the service for the changes to take effect.

You set the finalName property in the plugin configuration section:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.3.2</version>
    <configuration>
        <finalName>myJar</finalName>                   
    </configuration>
</plugin>       

As indicated in the official documentation.

Update:

For Maven >= 3

Based on Matthew's comment you can now do it like this:

 <packaging>jar</packaging>
 <build>
   <finalName>WhatEverYouLikey</finalName>
 </build>

See bug report/documentation.

I'd like to counter a few of the complaints made in this forum:

Maven is all-or-nothing. Or at least as far as I could tell from the documentation. You can't easily use maven as a drop-in replacement for ant, and gradually adopt more advanced features.

This isn't true. Maven's big win is using it to manage your dependencies in a rational way and if you want to do that in maven and do everything else in ant, you can. Here's how:

<?xml version="1.0" encoding="UTF-8"?>
<project name="foo" basedir="." xmlns:maven="antlib:org.apache.maven.artifact.ant" >
  <maven:dependencies verbose="true" pathId="maven.classpath">
    <maven:pom id="maven.pom" file="pom.xml" />
  </maven:dependencies>
</project>

You now have a classpath object named 'maven.classpath' which contains all the maven dependencies defined in the pom file. All you need is to put the maven ant tasks jar in your ant's lib directory.

Maven makes your build process dependent on your network connection.

The default dependency and plugin fetching process depends on a network connection, yes, but only for the initial build (or if you change the dependencies or plugins in use). After that all the jars are locally cached. And if you want to force no-network connection, you can tell maven to use offline mode.

It imposes rigid structure on you from the start.

Its not clear if this is referring to the file format or the 'convention versus configuration' issue. For the latter, there are a lot of invisible defaults like the expected location of java source files and resources, or the compatibility of the source. But this isn't rigidity, its putting in sensible defaults for you so you don't have to define them explicitly. All the settings can be overridden pretty easily (though for a beginner it can be hard to find in the documentation how to change certain things).

If you're talking about the file format, well that's covered in the response to the next part...

It's XML-based so it's as hard to read as ANT was.

First off, I don't see how you can complain that some aspect of something 'Isn't better than ant' as a justification for it having a bad rep. Second, while it still XML, the format of the XML is much more defined. Further, because its so defined, its a lot easier to make a sensible thick client editor for a POM. I've seen pages long ant build scripts that jump all over the place. Any ant build script editor isn't going to make that any more palatable, just another long list of interconnected tasks presented in a slightly different way.

Having said that there are a few complaints that I've seen here that have or had some vailidity, the biggest being

• Documentation is poor/missing
• Reproducible builds
• Eclipse integration is bad
• Bugs

To which my response is twofold. First, Maven is a much younger tool than Ant or Make, so you have to expect that its going to take time to get to the maturity level of those applications. Second is, well if you don't like it, fix it. Its an open source project and using it and then complaining about something that anyone can have a hand in solving seems fairly asinine to me. Don't like the documentation? Contribute to it to make it clearer, more complete or more accessible to a beginner.

Reproducible builds problem breaks down into two issues, version ranges and automatic maven plugin updates. For the plugin upates, well unless you're making sure when you rebuild a project a year later that you're using the exact same JDK and exact same Ant version, well this is just the same problem with a different name. For version ranges, I recommend working on a plugin that will produce a temporary pom with locked versions for all direct and transitive dependencies and make it part of the maven release lifecycle. That way your release build poms are always exact descriptions of all the dependencies.

The Android Studio build system is based on Gradle, and the Android Gradle plugin adds several features that are specific to building Android apps. Although the Android plugin is typically updated in lock-step with Android Studio, the plugin (and the rest of the Gradle system) can run independent of Android Studio and be updated separately.

For more details you can refer:

The best source is probably Apple's official documentation. The specific variable you are looking for is CONFIGURATION.

Use the maven-shade-plugin to package all dependencies into one uber-jar. It can also be used to build an executable jar by specifying the main class. After trying to use maven-assembly and maven-jar , I found that this plugin best suited my needs.

I found this plugin particularly useful as it merges content of specific files instead of overwriting them. This is needed when there are resource files that are have the same name across the jars and the plugin tries to package all the resource files

See example below

      <plugins>
    <!-- This plugin provides the capability to package the artifact in an uber-jar, including its dependencies and to shade - i.e. rename - the packages of some of the dependencies. -->

Short Answer

Use <foreach> with a nested <FileSet>

Foreach requires ant-contrib.

Updated Example for recent ant-contrib:

<target name="foo">
  <foreach target="bar" param="theFile">
    <fileset dir="${server.src}" casesensitive="yes">
      <include name="**/*.java"/>
      <exclude name="**/*Test*"/>
    </fileset>
  </foreach>
</target>

<target name="bar">
  <echo message="${theFile}"/>
</target>

This will antcall the target "bar" with the ${theFile} resulting in the current file.

<relativePath>

If you build under a child project, then <relativePath> can help you resolve the parent pom.

install parent pom

But if you build the child project out of its folder, <relativePath> doesn't work. You can install the parent pom into your local repository first, then build the child project.

I had a similar issue, and I could use customized Boost libraries by adding the below lines to my CMakeLists.txt file:

set(Boost_NO_SYSTEM_PATHS TRUE)
if (Boost_NO_SYSTEM_PATHS)
  set(BOOST_ROOT "${CMAKE_CURRENT_SOURCE_DIR}/../../3p/boost")
  set(BOOST_INCLUDE_DIRS "${BOOST_ROOT}/include")
  set(BOOST_LIBRARY_DIRS "${BOOST_ROOT}/lib")
endif (Boost_NO_SYSTEM_PATHS)
find_package(Boost REQUIRED regex date_time system filesystem thread graph program_options)
include_directories(${BOOST_INCLUDE_DIRS})

Check Using Filename filters like DB_*/**/*.sql

Here is a variation to perform an action if one or more files exist corresponding to a wildcard filter. That is, you don't know the exact name of the file.

Here, we are looking for "*.sql" files in any sub-directories called "DB_*", recursively. You can adjust the filter to your needs.

NB: Apache Ant 1.7 and higher!

Here is the target to set a property if matching files exist:

<target name="check_for_sql_files">
    <condition property="sql_to_deploy">
        <resourcecount when="greater" count="0">
            <fileset dir="." includes="DB_*/**/*.sql"/>
        </resourcecount>
    </condition>
</target>

Here is a "conditional" target that only runs if files exist:

<target name="do_stuff" depends="check_for_sql_files" if="sql_to_deploy">
    <!-- Do stuff here -->
</target>

In simple terms, a stack trace is a list of the method calls that the application was in the middle of when an Exception was thrown.

Simple Example

With the example given in the question, we can determine exactly where the exception was thrown in the application. Let's have a look at the stack trace:

Exception in thread "main" java.lang.NullPointerException
        at com.example.myproject.Book.getTitle(Book.java:16)
        at com.example.myproject.Author.getBookTitles(Author.java:25)
        at com.example.myproject.Bootstrap.main(Bootstrap.java:14)

This is a very simple stack trace. If we start at the beginning of the list of "at ...", we can tell where our error happened. What we're looking for is the topmost method call that is part of our application. In this case, it's:

at com.example.myproject.Book.getTitle(Book.java:16)

To debug this, we can open up Book.java and look at line 16, which is:

15   public String getTitle() {
16      System.out.println(title.toString());
17      return title;
18   }

This would indicate that something (probably title) is null in the above code.

Example with a chain of exceptions

Sometimes applications will catch an Exception and re-throw it as the cause of another Exception. This typically looks like:

34   public void getBookIds(int id) {
35      try {
36         book.getId(id);    // this method it throws a NullPointerException on line 22
37      } catch (NullPointerException e) {
38         throw new IllegalStateException("A book has a null property", e)
39      }
40   }

This might give you a stack trace that looks like:

Exception in thread "main" java.lang.IllegalStateException: A book has a null property
        at com.example.myproject.Author.getBookIds(Author.java:38)
        at com.example.myproject.Bootstrap.main(Bootstrap.java:14)
Caused by: java.lang.NullPointerException
        at com.example.myproject.Book.getId(Book.java:22)
        at com.example.myproject.Author.getBookIds(Author.java:36)
        ... 1 more

What's different about this one is the "Caused by". Sometimes exceptions will have multiple "Caused by" sections. For these, you typically want to find the "root cause", which will be one of the lowest "Caused by" sections in the stack trace. In our case, it's:

Caused by: java.lang.NullPointerException <-- root cause
        at com.example.myproject.Book.getId(Book.java:22) <-- important line

Again, with this exception we'd want to look at line 22 of Book.java to see what might cause the NullPointerException here.

More daunting example with library code

Usually stack traces are much more complex than the two examples above. Here's an example (it's a long one, but demonstrates several levels of chained exceptions):

In this example, there's a lot more. What we're mostly concerned about is looking for methods that are from our code, which would be anything in the com.example.myproject package. From the second example (above), we'd first want to look down for the root cause, which is:

Caused by: java.sql.SQLException

However, all the method calls under that are library code. So we'll move up to the "Caused by" above it, and look for the first method call originating from our code, which is:

at com.example.myproject.MyEntityService.save(MyEntityService.java:59)

Like in previous examples, we should look at MyEntityService.java on line 59, because that's where this error originated (this one's a bit obvious what went wrong, since the SQLException states the error, but the debugging procedure is what we're after).

I would typically do something like this (onblur), but it could be attached to any of the events:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>

<script type="text/javascript">
function CheckNo(sender){
    if(!isNaN(sender.value)){
        if(sender.value > 100 )
            sender.value = 100;
        if(sender.value < 0 )
            sender.value = 0;
    }else{
          sender.value = 0;
    }
}

</script>
</head>

<body>
<input type="text" onblur="CheckNo(this)" />
</body>
</html>

You could also use a dummy form arround it like:

<mat-card-footer>
<form (submit)="search(ref, id, forename, surname, postcode)" action="#">
  <button mat-raised-button type="submit" class="successButton" id="invSearch" title="Click to perform search." >Search</button>
</form>
</mat-card-footer>

the search function has to return false to make sure that the action doesn't get executed.
Just make sure the form is focused (should be when you have the input in the form) when you press enter.

Try disabling and enabling the textbox.

To complement the other answers: if you want to reset all background properties to their initial value (which includes background-color: transparent and background-image: none) without explicitly specifying any value such as transparent or none, you can do so by writing:

background: initial;

Use this query to create the new table with the values from existing table

CREATE TABLE New_Table_name AS SELECT * FROM Existing_table_Name; 

Now you can get all the values from existing table into newly created table.

a lot of people say to use int(x), and this works ok for most cases, but there is a little problem. If OP's result is:

x = 1.9999999999999999

it will round to

x = 2

after the 16th 9 it will round. This is not a big deal if you are sure you will never come across such thing. But it's something to keep in mind.

The manual is clear enough. Please specify what part you get stuck with after you work through it, I'd suggest:

https://developer.android.com/studio/publish/app-signing.html

Okay, a small overview without reference or eclipse around, so leave some space for errors, but it works like this

• Open your project in eclipse
• Press right-mouse - > tools (android tools?) - > export signed application (apk?)
• Go through the wizard:
• Make a new key-store. remember that password
• Sign your app
• Save it etc.

Also, from the link:

Compile and sign with Eclipse ADT

If you are using Eclipse with the ADT plugin, you can use the Export Wizard to export a signed .apk (and even create a new keystore, if necessary). The Export Wizard performs all the interaction with the Keytool and Jarsigner for you, which allows you to sign the package using a GUI instead of performing the manual procedures to compile, sign, and align, as discussed above. Once the wizard has compiled and signed your package, it will also perform package alignment with zip align. Because the Export Wizard uses both Keytool and Jarsigner, you should ensure that they are accessible on your computer, as described above in the Basic Setup for Signing.

To create a signed and aligned .apk in Eclipse:

1. Select the project in the Package Explorer and select File > Export.

2. Open the Android folder, select Export Android Application, and click Next.

   The Export Android Application wizard now starts, which will guide you through the process of signing your application, including steps for selecting the private key with which to sign the .apk (or creating a new keystore and private key).

3. Complete the Export Wizard and your application will be compiled, signed, aligned, and ready for distribution.

For Windows

Instead of

mongodb://localhost:27017/yourDatabase

Write

mongodb://yourComputerName:27017/yourDatabase

Example:

mongodb://Gabriel-Laptop:27017/shop

To find your computer/laptop name write in the search bar View your PC name and the name near Device name is the name you are looking for.

Note: I read somewhere that using localhost keyword in Windows OS for MongoDB is not recommended (most probably here).

just change state config to disable and choose what you want, background Image for disabled state

Some more info for you. AT commands you can send only if you are rooted. Than you can kill system process and send commands but you will need a reboot to allow your phone to receive and send calls =)))

I'm very hapy =) Now my Shake2MuteCall will get an update !

In order to block anything but numbers from being input into a text field but still allowing for other buttons to work (such as delete, shift, tab, etc.) look at a reference of the Javascript key codes; anything from 65 on up (to 222) can be blocked.

Using Jquery and Javascript, that would look like:

$('#textFieldId').keydown(function(event) {
    if ( event.keyCode > 64 ) {
        event.preventDefault();
    }
});

The key codes will be the same in Javascript whether or not Jquery is used.

As the Tutorial on Android background processing with Handlers, AsyncTask and Loaders on the Vogella site puts it:

The Handler class can be used to register to a thread and provides a simple channel to send data to this thread.

The AsyncTask class encapsulates the creation of a background process and the synchronization with the main thread. It also supports reporting progress of the running tasks.

And a Thread is basically the core element of multithreading which a developer can use with the following disadvantage:

If you use Java threads you have to handle the following requirements in your own code:

• Synchronization with the main thread if you post back results to the user interface
• No default for canceling the thread
• No default thread pooling
• No default for handling configuration changes in Android

And regarding the AsyncTask, as the Android Developer's Reference puts it:

AsyncTask enables proper and easy use of the UI thread. This class allows to perform background operations and publish results on the UI thread without having to manipulate threads and/or handlers.

AsyncTask is designed to be a helper class around Thread and Handler and does not constitute a generic threading framework. AsyncTasks should ideally be used for short operations (a few seconds at the most.) If you need to keep threads running for long periods of time, it is highly recommended you use the various APIs provided by the java.util.concurrent package such as Executor, ThreadPoolExecutor and FutureTask.

Update May 2015: I found an excellent series of lectures covering this topic.

This is the Google Search: Douglas Schmidt lecture android concurrency and synchronisation

This is the video of the first lecture on YouTube

All this is part of the CS 282 (2013): Systems Programming for Android from the Vanderbilt University. Here's the YouTube Playlist

Douglas Schmidt seems to be an excellent lecturer

Important: If you are at a point where you are considering to use AsyncTask to solve your threading issues, you should first check out ReactiveX/RxAndroid for a possibly more appropriate programming pattern. A very good resource for getting an overview is Learning RxJava 2 for Android by example.

To allow the app using formatted strings from resources you should correct your xml. So, for example

<string name="app_name">Your App name, ver.%d</string>

should be replaced with

<string name="app_name">Your App name, ver.%1$d</string>

You can see this for details.

It depends on what type of PHP variable you want to use in Javascript. For example, entire PHP objects with class methods cannot be used in Javascript. You can, however, use the built-in PHP JSON (JavaScript Object Notation) functions to convert simple PHP variables into JSON representations. For more information, please read the following links:

• PHP JSON Manual
• PHP json_encode function
• PHP json_decode function

You can generate the JSON representation of your PHP variable and then print it into your Javascript code when the page loads. For example:

<script type="text/javascript">
  var foo = <?php echo json_encode($bar); ?>;
</script>

for a = 1 to 100 step 1

Command line in Windows . Please use %%a if running in Batch file.

    for /L %a in (1,1,100) Do echo %a 

"input" worked for me.

var searchBar  = document.getElementById("searchBar");
searchBar.addEventListener("input", PredictSearch, false);

Use Object.keys to get an array of the properties on an object. Example:

var example = {
    foo1: { /* stuff1 */},
    foo2: { /* stuff2 */},
    foo3: { /* stuff3 */}
};

var keys = Object.keys(example); // => ["foo1", "foo2", "foo3"] (Note: the order here is not reliable)

Documentation and cross-browser shim provided here. An example of its use can be found in another one of my answers here.

Edit: for clarity, I just want to echo what was correctly stated in other answers: the key order in javascript objects is undefined.

If you have just one Read-Request

Combine the answer of @redsio with a temp-table (600K is not that much):

DROP TEMPORARY TABLE IF EXISTS tmp_randorder;
CREATE TABLE tmp_randorder (id int(11) not null auto_increment primary key, data_id int(11));
INSERT INTO tmp_randorder (data_id) select id from datatable;

And then take a version of @redsios Answer:

SELECT dt.*
FROM
       (SELECT (RAND() *
                     (SELECT MAX(id)
                        FROM tmp_randorder)) AS id)
        AS rnd
 INNER JOIN tmp_randorder rndo on rndo.id between rnd.id - 10 and rnd.id + 10
 INNER JOIN datatable AS dt on dt.id = rndo.data_id
 ORDER BY abs(rndo.id - rnd.id)
 LIMIT 1;

If the table is big, you can sieve on the first part:

INSERT INTO tmp_randorder (data_id) select id from datatable where rand() < 0.01;

If you have many read-requests

1. Version: You could keep the table tmp_randorder persistent, call it datatable_idlist. Recreate that table in certain intervals (day, hour), since it also will get holes. If your table gets really big, you could also refill holes

   select l.data_id as whole from datatable_idlist l left join datatable dt on dt.id = l.data_id where dt.id is null;

2. Version: Give your Dataset a random_sortorder column either directly in datatable or in a persistent extra table datatable_sortorder. Index that column. Generate a Random-Value in your Application (I'll call it $rand).

   select l.*
   from datatable l 
   order by abs(random_sortorder - $rand) desc 
   limit 1;
   

This solution discriminates the 'edge rows' with the highest and the lowest random_sortorder, so rearrange them in intervals (once a day).

Using query comprehension syntax you could achieve the orderby as follows:

var uniqueColors = (from dbo in database.MainTable
                    where dbo.Property
                    orderby dbo.Color.Name ascending
                    select dbo.Color.Name).Distinct();

Easiest fix ever:

for ( Window w : Window.getWindows() ) {
    GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().setFullScreenWindow( w );
}

Add to top of the code,

#!/usr/bin/python

Then, run the following command on the terminal,

chmod +x yourScriptFile

Tried invalidating cache, reimporting the project, switching to built-in Maven, removing the .m2 folder and its parts, - nothing worked. After I had completely broken Maven (while it had built the project successfully before, now it couldn't anymore), I had to reinstall it from scratch. It helped!

try this:

SELECT 
    t.*
    FROM TestData t
        INNER JOIN (SELECT
                        MIN(ID) as MinID
                        FROM TestData
                        WHERE SKU LIKE 'FOO-%'
                   ) dt ON t.ID=dt.MinID

EDIT
once the OP corrected his samle output (previously had only ONE result row, now has all shown), this is the correct query:

declare @TestData table (ID int, sku char(6), product varchar(15))
insert into @TestData values (1 ,  'FOO-23'      ,'Orange')
insert into @TestData values (2 ,  'BAR-23'      ,'Orange')
insert into @TestData values (3 ,  'FOO-24'      ,'Apple')
insert into @TestData values (4 ,  'FOO-25'      ,'Orange')

--basically the same as @Aaron Alton's answer:
SELECT
    dt.ID, dt.SKU, dt.Product
    FROM (SELECT
              ID, SKU, Product, ROW_NUMBER() OVER (PARTITION BY PRODUCT ORDER BY ID) AS RowID
              FROM @TestData
              WHERE  SKU LIKE 'FOO-%'
         ) AS dt
    WHERE dt.RowID=1
    ORDER BY dt.ID

I have ubuntu 14 and the other answers where no working for me

Interestingly enough, settting setAccessible(true), which skips the security checks, has a 20% reduction in cost.

Without setAccessible(true)

new A(), 70 ns
A.class.newInstance(), 214 ns
new A(), 84 ns
A.class.newInstance(), 229 ns

With setAccessible(true)

new A(), 69 ns
A.class.newInstance(), 159 ns
new A(), 85 ns
A.class.newInstance(), 171 ns

You can do it with the Object "ThreadGroup" and its parameter activeCount:

The normal way to plot plots with points in different colors in matplotlib is to pass a list of colors as a parameter.

E.g.:

import matplotlib.pyplot
matplotlib.pyplot.scatter([1,2,3],[4,5,6],color=['red','green','blue'])

When you have a list of lists and you want them colored per list. I think the most elegant way is that suggesyted by @DSM, just do a loop making multiple calls to scatter.

But if for some reason you wanted to do it with just one call, you can make a big list of colors, with a list comprehension and a bit of flooring division:

import matplotlib
import numpy as np

X = [1,2,3,4]
Ys = np.array([[4,8,12,16],
      [1,4,9,16],
      [17, 10, 13, 18],
      [9, 10, 18, 11],
      [4, 15, 17, 6],
      [7, 10, 8, 7],
      [9, 0, 10, 11],
      [14, 1, 15, 5],
      [8, 15, 9, 14],
       [20, 7, 1, 5]])
nCols = len(X)  
nRows = Ys.shape[0]

colors = matplotlib.cm.rainbow(np.linspace(0, 1, len(Ys)))

cs = [colors[i//len(X)] for i in range(len(Ys)*len(X))] #could be done with numpy's repmat
Xs=X*nRows #use list multiplication for repetition
matplotlib.pyplot.scatter(Xs,Ys.flatten(),color=cs)

cs = [array([ 0.5,  0. ,  1. ,  1. ]),
 array([ 0.5,  0. ,  1. ,  1. ]),
 array([ 0.5,  0. ,  1. ,  1. ]),
 array([ 0.5,  0. ,  1. ,  1. ]),
 array([ 0.28039216,  0.33815827,  0.98516223,  1.        ]),
 array([ 0.28039216,  0.33815827,  0.98516223,  1.        ]),
 array([ 0.28039216,  0.33815827,  0.98516223,  1.        ]),
 array([ 0.28039216,  0.33815827,  0.98516223,  1.        ]),
 ...
 array([  1.00000000e+00,   1.22464680e-16,   6.12323400e-17,
          1.00000000e+00]),
 array([  1.00000000e+00,   1.22464680e-16,   6.12323400e-17,
          1.00000000e+00]),
 array([  1.00000000e+00,   1.22464680e-16,   6.12323400e-17,
          1.00000000e+00]),
 array([  1.00000000e+00,   1.22464680e-16,   6.12323400e-17,
          1.00000000e+00])]

As per the DOM structure you can use below code:

var x = document.getElementById('mySelect');
     var txt = "";
     var val = "";
     for (var i = 0; i < x.length; i++) {
         txt +=x[i].text + ",";
         val +=x[i].value + ",";
      }

That version number (51.0) indicates that you are trying to run classes compiled for Java 7. You will need to recompile them for Java 6.

Note, however, that some features may no longer be compatible with Java 6, which is very old, and no longer (publicly) supported by Oracle.

To get value, use:

$.each($('input'),function(i,val){
    if($(this).attr("type")=="hidden"){
        var valueOfHidFiled=$(this).val();
        alert(valueOfHidFiled);
    }
});

or:

var valueOfHidFiled=$('input[type=hidden]').val();
alert(valueOfHidFiled);

To set value, use:

$('input[type=hidden]').attr('value',newValue);

Span does not have 'change' event by default. But you can add this event manually.

Listen to the change event of span.

$("#span1").on('change',function(){
     //Do calculation and change value of other span2,span3 here
     $("#span2").text('calculated value');
});

And wherever you change the text in span1. Trigger the change event manually.

$("#span1").text('test').trigger('change'); 

Here is exp.

$date_search_strtotime = strtotime(date("Y-m-d"));
echo 'Now strtotime date : '.$date_search_strtotime;
echo '<br>';
echo 'Now date from strtotime : '.date('Y-m-d',$date_search_strtotime);

The m000493 method seems to perform some kind of XOR encryption. This means that the same method can be used for both encrypting and decrypting the text. All you have to do is reverse m0001cd:

string p0 = Encoding.UTF8.GetString(Convert.FromBase64String("OBFZDT..."));

string result = m000493(p0, "_p0lizei.");
//    result == "gaia^unplugged^Ta..."

with return m0001cd(builder3.ToString()); changed to return builder3.ToString();.

I'm using Borland code here is the code ti_hund gives me some times a negativnumber but timing is fairly good.

#include <dos.h>

void main() 
{
struct  time t;
int Hour,Min,Sec,Hun;
gettime(&t);
Hour=t.ti_hour;
Min=t.ti_min;
Sec=t.ti_sec;
Hun=t.ti_hund;
printf("Start time is: %2d:%02d:%02d.%02d\n",
   t.ti_hour, t.ti_min, t.ti_sec, t.ti_hund);
....
your code to time
...

// read the time here remove Hours and min if the time is in sec

gettime(&t);
printf("\nTid Hour:%d Min:%d Sec:%d  Hundreds:%d\n",t.ti_hour-Hour,
                             t.ti_min-Min,t.ti_sec-Sec,t.ti_hund-Hun);
printf("\n\nAlt Ferdig Press a Key\n\n");
getch();
} // end main

A couple of methods that, if the char does not exists, return the original string.

This one cuts the string after the first occurrence of the pivot:

public static string truncateStringAfterChar(string input, char pivot){         
    int index = input.IndexOf(pivot);   
    if(index >= 0) {
        return input.Substring(index + 1);          
    }           
    return input;       
}

This one instead cuts the string after the last occurrence of the pivot:

public static string truncateStringAfterLastChar(string input, char pivot){         
    return input.Split(pivot).Last();   
}

When i started to learn Swift it was very difficult to realize why optional.

Lets think in this way. Let consider a class Person which has two property name and company.

class Person: NSObject {
    
    var name : String //Person must have a value so its no marked as optional
    var companyName : String? ///Company is optional as a person can be unemployed that is nil value is possible
    
    init(name:String,company:String?) {
        
        self.name = name
        self.companyName = company
        
    }
}

Now lets create few objects of Person

var tom:Person = Person.init(name: "Tom", company: "Apple")//posible
var bob:Person = Person.init(name: "Bob", company:nil) // also Possible because company is marked as optional so we can give Nil

But we can not pass Nil to name

var personWithNoName:Person = Person.init(name: nil, company: nil)

Now Lets talk about why we use optional?. Lets consider a situation where we want to add Inc after company name like apple will be apple Inc. We need to append Inc after company name and print.

print(tom.companyName+" Inc") ///Error saying optional is not unwrapped.
print(tom.companyName!+" Inc") ///Error Gone..we have forcefully unwrap it which is wrong approach..Will look in Next line
print(bob.companyName!+" Inc") ///Crash!!!because bob has no company and nil can be unwrapped.

Now lets study why optional takes into place.

if let companyString:String = bob.companyName{///Compiler safely unwrap company if not nil.If nil,no unwrap.
    
    print(companyString+" Inc") //Will never executed and no crash!!!
}

Lets replace bob with tom

if let companyString:String = tom.companyName{///Compiler safely unwrap company if not nil.If nil,no unwrap.
    
    print(companyString+" Inc") //Will executed and no crash!!!
}

And Congratulation! we have properly deal with optional?

So the realization points are

1. We will mark a variable as optional if its possible to be nil
2. If we want to use this variable somewhere in code compiler will remind you that we need to check if we have proper deal with that variable if it contain nil.

Thank you...Happy Coding

It declares a type based on what is assigned to it in the initialisation.

A simple example is that the code:

var i = 53;

Will examine the type of 53, and essentially rewrite this as:

int i = 53;

Note that while we can have:

long i = 53;

This won't happen with var. Though it can with:

var i = 53l; // i is now a long

Similarly:

var i = null; // not allowed as type can't be inferred.
var j = (string) null; // allowed as the expression (string) null has both type and value.

This can be a minor convenience with complicated types. It is more important with anonymous types:

var i = from x in SomeSource where x.Name.Length > 3 select new {x.ID, x.Name};
foreach(var j in i)
  Console.WriteLine(j.ID.ToString() + ":" + j.Name);

Here there is no other way of defining i and j than using var as there is no name for the types that they hold.

My explanation is in the code. :)

DECLARE @TestConvert VARCHAR(MAX) = '123456789.1234567'
BEGIN TRY
    SELECT CAST(@TestConvert AS DECIMAL(10, 4))
END TRY
BEGIN CATCH
    SELECT 'The reason you get the message "' + ERROR_MESSAGE() + '" is because DECIMAL(10, 4) only allows for 4 numbers after the decimal.'
END CATCH

-- Here's one way to truncate the string to a castable value.
SELECT CAST(LEFT(@TestConvert, (CHARINDEX('.', @TestConvert, 1) + 4)) AS DECIMAL(14, 4))

-- If you noticed, I changed it to DECIMAL(14, 4) instead of DECIMAL(10, 4) That's because this number has 14 digits, as proven below.
-- Read this for a better explanation as to what precision, scale and length mean: http://msdn.microsoft.com/en-us/library/ms190476(v=sql.105).aspx
SELECT LEN(LEFT(@TestConvert, (CHARINDEX('.', @TestConvert, 1) + 4)))

You could use the round function. If you use no second parameter (# of significant digits) then I think you will get the behavior you want.

IDLE output.

>>> round(2.99999999999)
3
>>> round(2.6)
3
>>> round(2.5)
3
>>> round(2.4)

The sequel gem adds an update_or_create method which seems to do what you're looking for.

For example if you are in the parent directory of you destination folders you can do:

for i in $(ls); do cp sourcefile $i; done

Generate an array of random floats or ints of the same length. Sort that array, and do corresponding swaps on your target array.

This yields a truly independent sort.

for springboot 2.1.7 working with url seems not to work. change with jdbcUrl instead.

In properties:

security:
      datasource:
        jdbcUrl: jdbc:mysql://ip:3306/security
        username: user
        password: pass

In java:

@ConfigurationProperties(prefix = "security.datasource")
@Bean("dataSource")
@Primary
public DataSource dataSource(){

    return DataSourceBuilder
            .create()
            .build();
}

I use this to get the Parent, similarly for child

$( this ).children( 'li.target' ).css("border", "3px double red");

Good Luck

I do it like this <center></center>

<div class="form-actions">
            <center>
                    <button type="submit" class="submit btn btn-primary ">
                        Sign In <i class="icon-angle-right"></i>
                    </button>
            </center>
</div>

Perhaps you could try ([^ ]+) .*, which should give you everything to the first blank in your first group.

For a one-page web application where I add scrollable sections dynamically, I trigger OSX's scrollbars by programmatically scrolling one pixel down and back up:

// Plain JS:
var el = document.getElementById('scrollable-section');
el.scrollTop = 1;
el.scrollTop = 0;

// jQuery:
$('#scrollable-section').scrollTop(1).scrollTop(0);

This triggers the visual cue fading in and out.

In ActiveForm just use:

<?=
    $form->field($model, 'state_id')
         ->dropDownList(['prompt' => '---- Select State ----'])
         ->label('State')
?>

Let me start out by saying that I don't recommend using the method I'm about to suggest. It's much better to use event driven development and bind events only to the elements you're interested in knowing whether or not the mouse is over with mouseover, mouseout, mouseenter, mouseleave, etc.

If you absolutely must have the ability to know which element the mouse is over, you'd need to write a function that binds the mouseover event to everything in the DOM, and then store whatever the current element is in some variable.

You could so something like this:

window.which_element_is_the_mouse_on = (function() {

    var currentElement;

    $("body *").on('mouseover', function(e) {
        if(e.target === e.currentTarget) {
            currentElement = this;
        }
    });

    return function() {
        console.log(currentElement);
    }
}());

Basically, I've created an immediate function which sets the event on all elements and stores the current element within the closure to minimize your footprint.

Here's a working demo that calls window.which_element_is_the_mouse_on every second and logs what element the mouse is currently over to the console.

                <rule name="Imported Rule 2" stopProcessing="true">
                    <match url="^(.*)$" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />
                        <add input="{R:1}" pattern="^(index\.php|images|robots\.txt|css)" ignoreCase="false" negate="true" />
                    </conditions>
                    <action type="Rewrite" url="index.php/{R:1}" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

and if you use .htaccess use this one :

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

Although you can resolve the problem by setting the listener to textview, it's recommended not to. You should use flat button as it is a subclass of Button and it provides many attributes which TextView doesn't.

To use flat button, add style="?android:attr/borderlessButtonStyle" attribute -

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="DONE"
    style="?android:attr/borderlessButtonStyle"/>

String str = "1234.56";
float num = 0.0f;

int digits = str.length()- str.indexOf('.') - 1;

float factor = 1f;

for(int i=0;i<digits;i++) factor /= 10;

for(int i=str.length()-1;i>=0;i--){

    if(str.charAt(i) == '.'){
        factor = 1;
        System.out.println("Reset, value="+num);
        continue;
    }

    num += (str.charAt(i) - '0') * factor;
    factor *= 10;
}

System.out.println(num);

The connector section has the parameter

maxPostSize

The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).

Another Limit is:

maxHttpHeaderSize The maximum size of the request and response HTTP header, specified in bytes. If not specified, this attribute is set to 4096 (4 KB).

You find them in

$TOMCAT_HOME/conf/server.xml

You can use parseInt() function to get the integer part than use that to extract the decimal part

var myNumber = 3.2;
var integerPart = parseInt(myNumber);
var decimalPart = myNumber - integerPart;

Or you could use regex like:

splitFloat = function(n){
   const regex = /(\d*)[.,]{1}(\d*)/;
   var m;

   if ((m = regex.exec(n.toString())) !== null) {
       return {
          integer:parseInt(m[1]),
          decimal:parseFloat(`0.${m[2]}`)
       }
   }
}

Here's a method I wrote to check if an URL exists or not. I had a requirement to add a request header. It's Groovy but should be fairly simple to adapt to Java. Essentially I'm using the org.springframework.web.client.RestTemplate#execute(java.lang.String, org.springframework.http.HttpMethod, org.springframework.web.client.RequestCallback, org.springframework.web.client.ResponseExtractor<T>, java.lang.Object...) API method. I guess the solution you arrive at depends at least in part on the HTTP method you want to execute. The key take away from example below is that I'm passing a Groovy closure (The third parameter to method restTemplate.execute(), which is more or less, loosely speaking a Lambda in Java world) that is executed by the Spring API as a callback to be able to manipulate the request object before Spring executes the command,

boolean isUrlExists(String url) {
    try {
      return (restTemplate.execute(url, HttpMethod.HEAD,
              { ClientHttpRequest request -> request.headers.add('header-name', 'header-value') },
              { ClientHttpResponse response -> response.headers }) as HttpHeaders)?.get('some-response-header-name')?.contains('some-response-header-value')
    } catch (Exception e) {
      log.warn("Problem checking if $url exists", e)
    }
    false
  }

I timed the

from numpy import genfromtxt
genfromtxt(fname = dest_file, dtype = (<whatever options>))

versus

import csv
import numpy as np
with open(dest_file,'r') as dest_f:
    data_iter = csv.reader(dest_f,
                           delimiter = delimiter,
                           quotechar = '"')
    data = [data for data in data_iter]
data_array = np.asarray(data, dtype = <whatever options>)

on 4.6 million rows with about 70 columns and found that the NumPy path took 2 min 16 secs and the csv-list comprehension method took 13 seconds.

I would recommend the csv-list comprehension method as it is most likely relies on pre-compiled libraries and not the interpreter as much as NumPy. I suspect the pandas method would have similar interpreter overhead.

You can use my StretchableImageView preserving the aspect ratio (by width or by height) depending on width and height of drawable:

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ImageView;

public class StretchableImageView extends ImageView{

    public StretchableImageView(Context context) {
        super(context);
    }

    public StretchableImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

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

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        if(getDrawable()!=null){
            if(getDrawable().getIntrinsicWidth()>=getDrawable().getIntrinsicHeight()){
                int width = MeasureSpec.getSize(widthMeasureSpec);
                int height = width * getDrawable().getIntrinsicHeight()
                            / getDrawable().getIntrinsicWidth();
                setMeasuredDimension(width, height);
            }else{
                int height = MeasureSpec.getSize(heightMeasureSpec);
                int width = height * getDrawable().getIntrinsicWidth()
                            / getDrawable().getIntrinsicHeight();
                setMeasuredDimension(width, height);
            }
        }
    }
}

I am using Windows 7, and I got the same problem as yours while using Composer via cmd.

The problem is solved when I use

php C:\ProgramData\ComposerSetup\bin\composer.phar create-project slim/slim-skeleton

instead of

php composer.phar create-project slim/slim-skeleton

Hope this is useful for people who got the same problem.

You can run the pipenv command with the --rm option as in:

pipenv --rm

This will remove the virtualenv created for you under ~/.virtualenvs

See https://pipenv.kennethreitz.org/en/latest/cli/#cmdoption-pipenv-rm

For powershell in Windows, you can add relative path + filename to --output flag:

curl -L  http://github.com/GorvGoyl/Notion-Boost-browser-extension/archive/master.zip --output build_firefox/master-repo.zip

here build_firefox is relative folder.

I had the same problem. Even JPG files did not work. Put all your image files into mipmap and work. They work perfectly.

Yes, the short-circuit evaluation for boolean expressions is the default behaviour in all the C-like family.

An interesting fact is that Java also uses the & and | as logic operands (they are overloaded, with int types they are the expected bitwise operations) to evaluate all the terms in the expression, which is also useful when you need the side-effects.

I'm not entirely sure of the general purpose of the function, but you could always do this:

function getMachine(color, qty) {
    var retval;
    $("#getMachine li").each(function() {
        var thisArray = $(this).text().split("~");
        if(thisArray[0] == color&& qty>= parseInt(thisArray[1]) && qty<= parseInt(thisArray[2])) {
            retval = thisArray[3];
            return false;
        }
    });
    return retval;
}

var retval = getMachine(color, qty);

There is another interesting issue with IE and Edge. Cookies that have names with more than 1 period seem to be silently dropped. So This works:

cookie_name_a=valuea

while this will get dropped

cookie.name.a=valuea

I use this handy function:

By downloading it with a 4094 byte step it will not full your memory

function download($file_source, $file_target) {
    $rh = fopen($file_source, 'rb');
    $wh = fopen($file_target, 'w+b');
    if (!$rh || !$wh) {
        return false;
    }

    while (!feof($rh)) {
        if (fwrite($wh, fread($rh, 4096)) === FALSE) {
            return false;
        }
        echo ' ';
        flush();
    }

    fclose($rh);
    fclose($wh);

    return true;
}

Usage:

     $result = download('http://url','path/local/file');

You can then check if everything is ok with:

     if (!$result)
         throw new Exception('Download error...');

Karan Bhandari's answer is good, but the AccountController added in a project is very likely a Mvc.Controller. To convert his answer for use in an ApiController change HttpContext.Current.GetOwinContext() to Request.GetOwinContext() and make sure you have added the following 2 using statements:

using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.Owin;

Yes. So the only way is at transaction time, e.g. using add, replace, or as part of the layout.

I determined this through an examination of the compatibility sources as I briefly looked for similar at some point in the past.

On my machine this only works in bin/idea.vmoptions, adding the setting in ~/Library/Preferences/IntelliJIdea12/idea.vmoptions causes the IDEA to hang during startup.

There is an other way to load jQuery dynamically (source). You could also use

document.write('<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"><\/script>');

It's considered bad practice to use document.write, but for sake of completion it's good to mention it.

See Why is document.write considered a "bad practice"? for the reasons. The pro is that document.write does block your page from loading other assests, so there is no need to create a callback function.

Use text-align:justify on the container, this way it will work no matter how many elements you have in your list (you don't have to work out % widths for each list item

    #nav {_x000D_
        text-align: justify;_x000D_
        min-width: 500px;_x000D_
    }_x000D_
    #nav:after {_x000D_
        content: '';_x000D_
        display: inline-block;_x000D_
        width: 100%;_x000D_
    }_x000D_
    #nav li {_x000D_
        display: inline-block;_x000D_
    }

<ul id="nav">_x000D_
    <li><a href="#">HOME</a></li>_x000D_
    <li><a href="#">ABOUT</a></li>_x000D_
    <li><a href="#">BASIC SERVICES</a></li>_x000D_
    <li><a href="#">OUR STAFF</a></li>_x000D_

</ul>

FIDDLE

With:

FILES = $(shell ls)

indented underneath all like that, it's a build command. So this expands $(shell ls), then tries to run the command FILES ....

If FILES is supposed to be a make variable, these variables need to be assigned outside the recipe portion, e.g.:

FILES = $(shell ls)
all:
        echo $(FILES)

Of course, that means that FILES will be set to "output from ls" before running any of the commands that create the .tgz files. (Though as Kaz notes the variable is re-expanded each time, so eventually it will include the .tgz files; some make variants have FILES := ... to avoid this, for efficiency and/or correctness.¹)

If FILES is supposed to be a shell variable, you can set it but you need to do it in shell-ese, with no spaces, and quoted:

all:
        FILES="$(shell ls)"

However, each line is run by a separate shell, so this variable will not survive to the next line, so you must then use it immediately:

        FILES="$(shell ls)"; echo $$FILES

This is all a bit silly since the shell will expand * (and other shell glob expressions) for you in the first place, so you can just:

        echo *

as your shell command.

Finally, as a general rule (not really applicable to this example): as esperanto notes in comments, using the output from ls is not completely reliable (some details depend on file names and sometimes even the version of ls; some versions of ls attempt to sanitize output in some cases). Thus, as l0b0 and idelic note, if you're using GNU make you can use $(wildcard) and $(subst ...) to accomplish everything inside make itself (avoiding any "weird characters in file name" issues). (In sh scripts, including the recipe portion of makefiles, another method is to use find ... -print0 | xargs -0 to avoid tripping over blanks, newlines, control characters, and so on.)

¹The GNU Make documentation notes further that POSIX make added ::= assignment in 2012. I have not found a quick reference link to a POSIX document for this, nor do I know off-hand which make variants support ::= assignment, although GNU make does today, with the same meaning as :=, i.e., do the assignment right now with expansion.

Note that VAR := $(shell command args...) can also be spelled VAR != command args... in several make variants, including all modern GNU and BSD variants as far as I know. These other variants do not have $(shell) so using VAR != command args... is superior in both being shorter and working in more variants.

An other way which makes then your jsfiddle less buggy (needed double click on open).

This doesn't use any delegated event to body level

Set tabindex="-1" to DIV .popup ( and for style CSS outline:0 )

DEMO

$(".link").click(function(e){
    e.preventDefault();
    $(".popup").fadeIn(300,function(){$(this).focus();});
});

$('.close').click(function() {
   $(".popup").fadeOut(300);
});
$(".popup").on('blur',function(){
    $(this).fadeOut(300);
});

You can just run "Java VisualVM" which is located at jdk/bin/jvisualvm.exe

This will open a GUI, use the "File" menu -> "Load..." then choose your *.hprof file

That's it, you're done!

In the spirit of a DVCS (as in "Distributed"), you don't cancel something you have published:
Pull requests are essentially patches you have send (normally by email, here by GitHub webapp), and you wouldn't cancel an email either ;)

But since the GitHub Pull Request system also includes a discussion section, that would be there that you could voice your concern to the recipient of those changes, asking him/her to disregards 29 of your 30 commits.

Finally, remember:

• a/ you have a preview section when making a pull request, allowing you to see the number of commits about to be included in it, and to review their diff.
• b/ it is preferable to rebase the work you want to publish as pull request on top of the remote branch which will receive said work. Then you can make a pull request which could be safely applied in a fast forward manner by the recipient.

That being said, since January 2011 ("Refreshed Pull Request Discussions"), and mentioned in the answer above, you can close a pull request in the comments.
Look for that "Comment and Close" button at the bottom of the discussion page:

If you are trying to keep a list of lists (similar to python's list.append()) then this might work:

a <- list(1,2,3)
b <- list(4,5,6)
c <- append(list(a), list(b))

> c

The SSL errors are often thrown by network management software such as Cyberroam.

To answer your question,

you will have to enter badidea into Chrome every time you visit a website.

You might at times have to enter it more than once, as the site may try to pull in various resources before load, hence causing multiple SSL errors

To iterate through all the inputs in a form you can do this:

$("form#formID :input").each(function(){
 var input = $(this); // This is the jquery object of the input, do what you will
});

This uses the jquery :input selector to get ALL types of inputs, if you just want text you can do :

$("form#formID input[type=text]")//...

etc.

Comparable is for providing a default ordering on data objects, for example if the data objects have a natural order.

A Comparator represents the ordering itself for a specific use.

I just clicked on the debug icon and it started working.

If you don't know the main activity, then the package name can be used to launch the application.

Intent launchIntent = getPackageManager().getLaunchIntentForPackage("com.package.address");
if (launchIntent != null) { 
    startActivity(launchIntent);//null pointer check in case package name was not found
}

Problem:

Try running below(without solution) from Internet Explorer and see the result.

console.log("abcde".includes("cd"));

Solution:

Now run below solution and check the result

if (!String.prototype.includes) {//To check browser supports or not_x000D_
  String.prototype.includes = function (str) {//If not supported, then define the method_x000D_
    return this.indexOf(str) !== -1;_x000D_
  }_x000D_
}_x000D_
console.log("abcde".includes("cd"));

jquery provides one more function: eq

Select first tr

$(".bootgrid-table tr").eq(0).addClass("black");

Select second tr

$(".bootgrid-table tr").eq(1).addClass("black");

I wanted to bind a particular data to dropdown and it should be distinct. I did the following:

List<ClassDetails> classDetails;
List<string> classDetailsData = classDetails.Select(dt => dt.Data).Distinct.ToList();
ddlData.DataSource = classDetailsData;
ddlData.Databind();

See if it helps

"List" is an object getting from backend and using iterator to display in table

"minAmount" , "MaxAmount" is an object variable "mrr" is an just temporary var to get value and iterate mrr to get data.

Many of answers use deprecated code, or code available on higer API versions. Now I use something like this

ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        if(connectivityManager != null) {
            for (Network net : connectivityManager.getAllNetworks()) {
                NetworkCapabilities nc = connectivityManager.getNetworkCapabilities(net);
                if (nc != null && nc.hasTransport(NetworkCapabilities.TRANSPORT_WIFI)
                        && nc.hasCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET))
                    return true;
            }
        }
        return false;

It affects at least NetBeans versions 7.4 through 8.0.2. It was first reported from version 8.0 and fixed in NetBeans 8.1. It would have had the problem for any tomcat version (confirmed for versions 7.0.56 through 8.0.28).

Specifics are described as Netbeans bug #248182.

This problem is also related to postings mentioning the following error output:

'127.0.0.1*' is not recognized as an internal or external command, operable program or batch file.

For a tomcat installed from the zip file, I fixed it by changing the catalina.bat file in the tomcat bin directory.

Find the bellow configuration in your catalina.bat file.

:noJuliConfig
set "JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG%"

:noJuliManager
set "JAVA_OPTS=%JAVA_OPTS% %LOGGING_MANAGER%"

And change it as in below by removing the double quotes:

:noJuliConfig
set JAVA_OPTS=%JAVA_OPTS% %LOGGING_CONFIG%

:noJuliManager
set JAVA_OPTS=%JAVA_OPTS% %LOGGING_MANAGER%

Now save your changes, and start your tomcat from within NetBeans.

This will download a yaml file that will map all timezones to an array of their zipcodes:

curl https://gist.githubusercontent.com/anonymous/01bf19b21da3424f6418/raw/0d69a384f55c6f68244ddaa07e0c2272b44cb1de/timezones_to_zipcodes.yml > timezones_to_zipcodes.yml

e.g.

"Eastern Time (US & Canada)" => ["00100", "00101", "00102", "00103", "00104", ...]
"Central Time (US & Canada)" => ["35000", "35001", "35002", "35003", "35004", ...]
etc...

If you prefer the shortened timezones, you can run this one:

curl https://gist.githubusercontent.com/anonymous/4e04970131ca82945080/raw/e85876daf39a823e54d17a79258b170d0a33dac0/timezones_to_zipcodes_short.yml > timezones_to_zipcodes.yml

e.g.

"EDT" => ["00100", "00101", "00102", "00103", "00104", ...]
"CDT" => ["35000", "35001", "35002", "35003", "35004", ...]
etc...

You can use following java code to get new inserted id.

ps = con.prepareStatement(query, Statement.RETURN_GENERATED_KEYS);
ps.setInt(1, quizid);
ps.setInt(2, userid);
ps.executeUpdate();

ResultSet rs = ps.getGeneratedKeys();
if (rs.next()) {
    lastInsertId = rs.getInt(1);
}

If the user exists you can get the user in user_object else user_object will be None.

try:
    user_object = User.objects.get(email = cleaned_info['username'])
except User.DoesNotExist:
    user_object = None
if user_object:
    # user exist
    pass
else:
    # user does not exist
    pass

IMHO the method UserForm_Initialize should remain private bacause it is event handler for Initialize event of the UserForm.

This event handler is called when new instance of the UserForm is created. In this even handler u can initialize the private members of UserForm1 class.

Example:

Standard module code:

Option Explicit

Public Sub Main()
  Dim myUserForm As UserForm1

  Set myUserForm = New UserForm1
  myUserForm.Show

End Sub

User form code:

Option Explicit

Private m_initializationDate As Date

Private Sub UserForm_Initialize()
  m_initializationDate = VBA.DateTime.Date
  MsgBox "Hi from UserForm_Initialize event handler.", vbInformation
End Sub

FirebaseInstanceId class and it's method getInstanceId are also deprecated. So you have to use FirebaseMessaging class and it's getToken method instead.

FirebaseMessaging.getInstance().getToken().addOnSuccessListener(token -> {
        if (!TextUtils.isEmpty(token)) {
            Log.d(TAG, "retrieve token successful : " + token);
        } else{
            Log.w(TAG, "token should not be null...");
        }
    }).addOnFailureListener(e -> {
        //handle e
    }).addOnCanceledListener(() -> {
        //handle cancel
    }).addOnCompleteListener(task -> Log.v(TAG, "This is the token : " + task.getResult()));

The method getToken() is deprecated. You can use getInstanceId() instead.

FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(instanceIdResult -> {
        if (instanceIdResult != null) {
            String token = instanceIdResult.getToken();
            if (!TextUtils.isEmpty(token)) {
                Log.d(TAG, "retrieve token successful : " + token);
            }
        } else{
            Log.w(TAG, "instanceIdResult should not be null..");
        }
    }).addOnFailureListener(e -> {
        //do something with e
    }).addOnCanceledListener(() -> {
        //request has canceled
    }).addOnCompleteListener(task -> Log.v(TAG, "task result : " + task.getResult().getToken()));

Another reason this can happen:

The component you are using formControl in is not declared in a module that imports the ReactiveFormsModule.

So check the module that declares the component that throws this error.

When writing queries, this difference should be kept in mind :

DECLARE @A INT = 2

SELECT  @A = TBL.A
FROM    ( SELECT 1 A ) TBL
WHERE   1 = 2

SELECT  @A
/* @A is 2*/

---------------------------------------------------------------

DECLARE @A INT = 2

SET @A = ( 
            SELECT  TBL.A
            FROM    ( SELECT 1 A) TBL
            WHERE   1 = 2
         )

SELECT  @A
/* @A is null*/

Try to update the below two parameters as they must be having default values.

innodb_lock_wait_timeout = 50

innodb_rollback_on_timeout = ON

For checking parameter value you can use the below SQL.

SHOW GLOBAL VARIABLES LIKE 'innodb_rollback_on_timeout';

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

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

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

Inside a serializable transaction with lock hints:

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

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

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

    ELSE 

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

  COMMIT

Here is how to make a 2 dimensional list

        // Generating lists in a loop.
        List<List<string>> biglist = new List<List<string>>();

        for(int i = 1; i <= 10; i++)
        {
            List<string> list1 = new List<string>();
            biglist.Add(list1);
        }

        // Populating the lists
        for (int i = 0; i < 10; i++)
        {
            for(int j = 0; j < 10; j++)
            {
                biglist[i].Add((i).ToString() + " " + j.ToString());
            }
        }

        textbox1.Text = biglist[5][9] + "\n";

Be aware of the danger of accessing a location that is not populated.

Add a key, value pair to dictionary

aDict = {}
aDict[key] = value

What do you mean by dynamic addition.

This works:

private static void showKeyboard(Activity activity) {
    View view = activity.getCurrentFocus();
    InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}

And you call this method like this:

showKeyboard(NameOfActivity.this);

Bootstrap 4

<div class="col-md-9 col-xs-12 text-md-left text-center">md left, xs center</div>
<div class="col-md-9 col-xs-12 text-md-right text-center">md right, xs center</div>

Please find below a way that works on all browsers. Basically I put the input on top the image. I make it huge using font-size so the user is always clicking the upload button.

.myFile {_x000D_
  position: relative;_x000D_
  overflow: hidden;_x000D_
  float: left;_x000D_
  clear: left;_x000D_
}_x000D_
.myFile input[type="file"] {_x000D_
  display: block;_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  right: 0;_x000D_
  opacity: 0;_x000D_
  font-size: 100px;_x000D_
  filter: alpha(opacity=0);_x000D_
  cursor: pointer;_x000D_
}

<label class="myFile">_x000D_

A good idea is to set all of the "" (blank cells) to NA before any further analysis.

If you are reading your input from a file, it is a good choice to cast all "" to NAs:

foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited

If you have already your table loaded, you can act as follows:

foo[foo==""] <- NA

Then to keep only rows with no NA you may just use na.omit():

foo <- na.omit(foo)

Or to keep columns with no NA:

foo <- foo[, colSums(is.na(foo)) == 0] 

This is my first crack at a query, based on Andomar's suggestions. This query is intended to provide a list of permissions that a user has either applied directly to the user account, or through roles that the user has.

Security Audit Report
1) List all access provisioned to a sql user or windows user/group directly 
2) List all access provisioned to a sql user or windows user/group through a database or application role
3) List all access provisioned to the public role

Columns Returned:
UserName        : SQL or Windows/Active Directory user account.  This could also be an Active Directory group.
UserType        : Value will be either 'SQL User' or 'Windows User'.  This reflects the type of user defined for the 
                  SQL Server user account.
DatabaseUserName: Name of the associated user as defined in the database user account.  The database user may not be the
                  same as the server user.
Role            : The role name.  This will be null if the associated permissions to the object are defined at directly
                  on the user account, otherwise this will be the name of the role that the user is a member of.
PermissionType  : Type of permissions the user/role has on an object. Examples could include CONNECT, EXECUTE, SELECT
                  DELETE, INSERT, ALTER, CONTROL, TAKE OWNERSHIP, VIEW DEFINITION, etc.
                  This value may not be populated for all roles.  Some built in roles have implicit permission
                  definitions.
PermissionState : Reflects the state of the permission type, examples could include GRANT, DENY, etc.
                  This value may not be populated for all roles.  Some built in roles have implicit permission
                  definitions.
ObjectType      : Type of object the user/role is assigned permissions on.  Examples could include USER_TABLE, 
                  SQL_SCALAR_FUNCTION, SQL_INLINE_TABLE_VALUED_FUNCTION, SQL_STORED_PROCEDURE, VIEW, etc.   
                  This value may not be populated for all roles.  Some built in roles have implicit permission
                  definitions.          
ObjectName      : Name of the object that the user/role is assigned permissions on.  
                  This value may not be populated for all roles.  Some built in roles have implicit permission
                  definitions.
ColumnName      : Name of the column of the object that the user/role is assigned permissions on. This value
                  is only populated if the object is a table, view or a table value function.

Things have changed in HTML5:

ASPX:

<asp:TextBox ID="txtBox" runat="server" maxlength="2000" TextMode="MultiLine"></asp:TextBox>

C#:

if (!IsPostBack)
{
    txtBox.Attributes.Add("maxlength", txtBox.MaxLength.ToString());
}

Rendered HTML:

<textarea name="ctl00$DemoContentPlaceHolder$txtBox" id="txtBox" maxlength="2000"></textarea>

The metadata for Attributes:

Summary: Gets the collection of arbitrary attributes (for rendering only) that do not correspond to properties on the control.

Returns: A System.Web.UI.AttributeCollection of name and value pairs.

To find a very long list of words in big files, it can be more efficient to use egrep:

remove the last \n of A
$ tr '\n' '|' < A > A_regex
$ egrep -f A_regex B

Looks like you're missing the SEPARATOR keyword in the GROUP_CONCAT function.

GROUP_CONCAT(artists.artistname SEPARATOR '----')

The way you've written it, you're concatenating artists.artistname with the '----' string using the default comma separator.

Here's a way you can do it asynchronously and manage things like you would normally. Everything is still shared. You get a reference to the object that you want updated. Whenever you update that in your service, it gets updated globally without having to watch or return a promise. This is really nice because you can update the underlying object from within the service without ever having to rebind. Using Angular the way it's meant to be used. I think it's probably a bad idea to make $http.get/post synchronous. You'll get a noticeable delay in the script.

app.factory('AssessmentSettingsService', ['$http', function($http) {
    //assessment is what I want to keep updating
    var settings = { assessment: null };

    return {
        getSettings: function () {
             //return settings so I can keep updating assessment and the
             //reference to settings will stay in tact
             return settings;
        },
        updateAssessment: function () {
            $http.get('/assessment/api/get/' + scan.assessmentId).success(function(response) {
                //I don't have to return a thing.  I just set the object.
                settings.assessment = response;
            });
        }
    };
}]);

    ...
        controller: ['$scope', '$http', 'AssessmentSettingsService', function ($scope, as) {
            $scope.settings = as.getSettings();
            //Look.  I can even update after I've already grabbed the object
            as.updateAssessment();

And somewhere in a view:

<h1>{{settings.assessment.title}}</h1>

In contrast to SGB's answer, I prefer doing the regexp defining the actual format of my data and negating that. This allows me to define values like $DDD,DDD,DDD.DD In the OPs simple scenario, it would look like

SELECT * 
FROM table_with_column_to_search 
WHERE NOT REGEXP_LIKE(varchar_col_with_non_numerics, '^[0-9]+$');

which finds all non-positive integers. If you wau accept negatiuve integers also, it's an easy change, just add an optional leading minus.

SELECT * 
FROM table_with_column_to_search 
WHERE NOT REGEXP_LIKE(varchar_col_with_non_numerics, '^-?[0-9]+$');

accepting floating points...

SELECT * 
FROM table_with_column_to_search 
WHERE NOT REGEXP_LIKE(varchar_col_with_non_numerics, '^-?[0-9]+(\.[0-9]+)?$');

Same goes further with any format. Basically, you will generally already have the formats to validate input data, so when you will desire to find data that does not match that format ... it's simpler to negate that format than come up with another one; which in case of SGB's approach would be a bit tricky to do if you want more than just positive integers.

You can use the xmp element, see What was the <XMP> tag used for?. It has been in HTML since the beginning and is supported by all browsers. Specifications frown upon it, but HTML5 CR still describes it and requires browsers to support it (though it also tells authors not to use it, but it cannot really prevent you).

Everything inside xmp is taken as such, no markup (tags or character references) is recognized there, except, for apparent reason, the end tag of the element itself, </xmp>.

Otherwise xmp is rendered like pre.

When using “real XHTML”, i.e. XHTML served with an XML media type (which is rare), the special parsing rules do not apply, so xmp is treated like pre. But in “real XHTML”, you can use a CDATA section, which implies similar parsing rules. It has no special formatting, so you would probably want to wrap it inside a pre element:

<pre><![CDATA[
This is a demo, tags like <p> will
appear literally.
]]></pre>

I don’t see how you could combine xmp and CDATA section to achieve so-called polyglot markup

In my case, there is a single table which happens to be a device list from a router. If you wish to read the table using TR/TH/TD (row, header, data) instead of a matrix as mentioned above, you can do something like the following:

    List<TableRow> deviceTable = (from table in document.DocumentNode.SelectNodes(XPathQueries.SELECT_TABLE)
                                       from row in table?.SelectNodes(HtmlBody.TR)
                                       let rows = row.SelectSingleNode(HtmlBody.TR)
                                       where row.FirstChild.OriginalName != null && row.FirstChild.OriginalName.Equals(HtmlBody.T_HEADER)
                                       select new TableRow
                                       {
                                           Header = row.SelectSingleNode(HtmlBody.T_HEADER)?.InnerText,
                                           Data = row.SelectSingleNode(HtmlBody.T_DATA)?.InnerText}).ToList();
                                       }  

TableRow is just a simple object with Header and Data as properties. The approach takes care of null-ness and this case:

<tr>_x000D_
    <td width="28%">&nbsp;</td>_x000D_
</tr>

which is row without a header. The HtmlBody object with the constants hanging off of it are probably readily deduced but I apologize for it even still. I came from the world where if you have " in your code, it should either be constant or localizable.

Here is the reason. Starting from Jersey 2.26, Jersey removed HK2 as a hard dependency. It created an SPI as a facade for the dependency injection provider, in the form of the InjectionManager and InjectionManagerFactory. So for Jersey to run, we need to have an implementation of the InjectionManagerFactory. There are two implementations of this, which are for HK2 and CDI. The HK2 dependency is the jersey-hk2 others are talking about.

<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-hk2</artifactId>
    <version>2.26</version>
</dependency>

The CDI dependency is

<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-cdi2-se</artifactId>
    <version>2.26</version>
</dependency>

This (jersey-cdi2-se) should only be used for SE environments and not EE environments.

Jersey made this change to allow others to provide their own dependency injection framework. They don't have any plans to implement any other InjectionManagers, though others have made attempts at implementing one for Guice.

I dont know about XamGrid but that's what i'll do with a standard wpf DataGrid:

<DataGrid>
    <DataGrid.Columns>
        <DataGridTemplateColumn>
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
            <DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellEditingTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

Since the TextBlock and the TextBox specified in the cell templates will be part of the visual tree, you can walk up and find whatever control you need.

I have to add to Collin Andersons answer that this method also takes into account if you have two interfaces and they're both showing as up.

ip route get 1 | awk '{print $NF;exit}'

I have been working on an application with Raspberry Pi's and needed the IP address that was actually being used not just whether it was up or not. Most of the other answers will return both IP address which isn't necessarily helpful - for my scenario anyway.

make sure that you are using the same namespace as your pages

I have just faced with similar issue building LLVM 3.7 version. first check whether you have installed the required library on your system:

$locate libstdc++.so.6.*

Then add the found location to your $LD_LIBRARY_PATH environment variable.

Considering the previous answers, it is necessary to be careful with globalized characters.

UrlEncode result to download: "Esdrújula+prenda+ñame+-+güena.jpg" [OK]

Then, you need almost always to use the UrlEncode over the file name. Moreover, if you set the content-disposition header as direct string, then you need to ensure surround with quotes to avoid browser compatibility issues.

Response.AddHeader("Content-Disposition", $"attachment; filename=\"{HttpUtility.UrlEncode(YourFilename)}\"");

or with class aid:

var cd = new ContentDisposition("attachment") { FileName = HttpUtility.UrlEncode(resultFileName) };
Response.AddHeader("Content-Disposition", cd.ToString());

The System.Net.Mime.ContentDisposition class takes care of quotes.

Solution

You can now use base64 files to produce sounds when imported as data URI. The solution is almost the same as the previous ones, except you do not need to import an external audio file.

function beep() {
    var snd = new Audio("data:audio/wav;base64,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");

If the HTTP Connection doesn't timeout, You can implement the timeout checker in the background thread itself (AsyncTask, Service, etc), the following class is an example for Customize AsyncTask which timeout after certain period

public abstract class AsyncTaskWithTimer<Params, Progress, Result> extends
    AsyncTask<Params, Progress, Result> {

private static final int HTTP_REQUEST_TIMEOUT = 30000;

@Override
protected Result doInBackground(Params... params) {
    createTimeoutListener();
    return doInBackgroundImpl(params);
}

private void createTimeoutListener() {
    Thread timeout = new Thread() {
        public void run() {
            Looper.prepare();

            final Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {

                    if (AsyncTaskWithTimer.this != null
                            && AsyncTaskWithTimer.this.getStatus() != Status.FINISHED)
                        AsyncTaskWithTimer.this.cancel(true);
                    handler.removeCallbacks(this);
                    Looper.myLooper().quit();
                }
            }, HTTP_REQUEST_TIMEOUT);

            Looper.loop();
        }
    };
    timeout.start();
}

abstract protected Result doInBackgroundImpl(Params... params);
}

A Sample for this

public class AsyncTaskWithTimerSample extends AsyncTaskWithTimer<Void, Void, Void> {

    @Override
    protected void onCancelled(Void void) {
        Log.d(TAG, "Async Task onCancelled With Result");
        super.onCancelled(result);
    }

    @Override
    protected void onCancelled() {
        Log.d(TAG, "Async Task onCancelled");
        super.onCancelled();
    }

    @Override
    protected Void doInBackgroundImpl(Void... params) {
        // Do background work
        return null;
    };
 }

Check your migration file, maybe you are using Schema::table, like this:

Schema::table('table_name', function ($table)  {
    // ...
});

If you want to create a new table you must use Schema::create:

Schema::create('table_name', function ($table)  {
    // ...
});

If you want to print the array like you print a 2D list in Python:

#include <stdio.h>

int main()
{
  int i, j;
  int my_array[3][3] = {{10, 23, 42}, {1, 654, 0}, {40652, 22, 0}};
  for(i = 0; i < 3; i++)
  {
      if (i == 0) {
          printf("[");
      }
      printf("[");
      for(j = 0; j < 3; j++)
      {
         printf("%d", my_array[i][j]);
         if (j < 2) {
             printf(", ");
         }
      }
    printf("]");
    if (i == 2) {
        printf("]");
    }

    if (i < 2) {
        printf(", ");
    }
  }
  return 0;
}

Output will be:

[[10, 23, 42], [1, 654, 0], [40652, 22, 0]]

As stated in one of the comments (burried) above, this can be fixed by not placing the button tag inside the form tag. When the button is outside the form, the page does not refresh itself.

my addition to all the answers

function deepCopy(arr) {
  if (typeof arr !== 'object') return arr
  if (Array.isArray(arr)) return [...arr].map(deepCopy)
  for (const prop in arr) 
    copy[prop] = deepCopy(arr[prop])
  return copy
}

If you lost a keystore file, don't create/update the new one with another set of value. First do the thorough search. Because it will overwrite the old one, so it will not match to your previous apk.

If you use eclipse most probably it will store in default path. For MAC (eclipse) it will be in your elispse installation path something like:

/Applications/eclipse/Eclipse.app/Contents/MacOS/

then your keystore file without any extension. You need root privilege to access this path (file).

The documentation on CREATE EVENT is quite good, but it takes a while to get it right.

You have two problems, first, making the event recur, second, making it run at 13:00 daily.

This example creates a recurring event.

CREATE EVENT e_hourly
    ON SCHEDULE
      EVERY 1 HOUR
    COMMENT 'Clears out sessions table each hour.'
    DO
      DELETE FROM site_activity.sessions;

When in the command-line MySQL client, you can:

SHOW EVENTS;

This lists each event with its metadata, like if it should run once only, or be recurring.

The second problem: pointing the recurring event to a specific schedule item.

By trying out different kinds of expression, we can come up with something like:

CREATE EVENT IF NOT EXISTS `session_cleaner_event`
ON SCHEDULE
  EVERY 13 DAY_HOUR
  COMMENT 'Clean up sessions at 13:00 daily!'
  DO
    DELETE FROM site_activity.sessions;

If the port says Already used, then you are probably using the wrong port.

Switch it to the port where you connected your Arduino and then try to re-upload, you will definitely see it work.

The solution with the anonymous type should work fine. LINQ can only represent equijoins (with join clauses, anyway), and indeed that's what you've said you want to express anyway based on your original query.

If you don't like the version with the anonymous type for some specific reason, you should explain that reason.

If you want to do something other than what you originally asked for, please give an example of what you really want to do.

EDIT: Responding to the edit in the question: yes, to do a "date range" join, you need to use a where clause instead. They're semantically equivalent really, so it's just a matter of the optimisations available. Equijoins provide simple optimisation (in LINQ to Objects, which includes LINQ to DataSets) by creating a lookup based on the inner sequence - think of it as a hashtable from key to a sequence of entries matching that key.

Doing that with date ranges is somewhat harder. However, depending on exactly what you mean by a "date range join" you may be able to do something similar - if you're planning on creating "bands" of dates (e.g. one per year) such that two entries which occur in the same year (but not on the same date) should match, then you can do it just by using that band as the key. If it's more complicated, e.g. one side of the join provides a range, and the other side of the join provides a single date, matching if it falls within that range, that would be better handled with a where clause (after a second from clause) IMO. You could do some particularly funky magic by ordering one side or the other to find matches more efficiently, but that would be a lot of work - I'd only do that kind of thing after checking whether performance is an issue.

This is almost like the other answer but you don't need a scatter plot at all, you can simply specify a scatter-plot-like format (fmt-parameter) for errorbar:

import matplotlib.pyplot as plt
x = [1, 2, 3, 4]
y = [1, 4, 9, 16]
e = [0.5, 1., 1.5, 2.]
plt.errorbar(x, y, yerr=e, fmt='o')
plt.show()

Result:

A list of the avaiable fmt parameters can be found for example in the plot documentation:

character   description
'-'     solid line style
'--'    dashed line style
'-.'    dash-dot line style
':'     dotted line style
'.'     point marker
','     pixel marker
'o'     circle marker
'v'     triangle_down marker
'^'     triangle_up marker
'<'     triangle_left marker
'>'     triangle_right marker
'1'     tri_down marker
'2'     tri_up marker
'3'     tri_left marker
'4'     tri_right marker
's'     square marker
'p'     pentagon marker
'*'     star marker
'h'     hexagon1 marker
'H'     hexagon2 marker
'+'     plus marker
'x'     x marker
'D'     diamond marker
'd'     thin_diamond marker
'|'     vline marker
'_'     hline marker

The answer by Chinmay Kanchi is excellent but I wanted an example of a function which passes and returns a variables/arrays to a C++ code. I though I'd include it here in case it is useful to others.

Passing and returning an integer

The C++ code for a function which takes an integer and adds one to the returned value,

extern "C" int add_one(int i)
{
    return i+1;
}

Saved as file test.cpp, note the required extern "C" (this can be removed for C code). This is compiled using g++, with arguments similar to Chinmay Kanchi answer,

g++ -shared -o testlib.so -fPIC test.cpp

The Python code uses load_library from the numpy.ctypeslib assuming the path to the shared library in the same directory as the Python script,

import numpy.ctypeslib as ctl
import ctypes

libname = 'testlib.so'
libdir = './'
lib=ctl.load_library(libname, libdir)

py_add_one = lib.add_one
py_add_one.argtypes = [ctypes.c_int]
value = 5
results = py_add_one(value)
print(results)

This prints 6 as expected.

Passing and printing an array

You can also pass arrays as follows, for a C code to print the element of an array,

extern "C" void print_array(double* array, int N)
{
    for (int i=0; i<N; i++) 
        cout << i << " " << array[i] << endl;
}

which is compiled as before and the imported in the same way. The extra Python code to use this function would then be,

import numpy as np

py_print_array = lib.print_array
py_print_array.argtypes = [ctl.ndpointer(np.float64, 
                                         flags='aligned, c_contiguous'), 
                           ctypes.c_int]
A = np.array([1.4,2.6,3.0], dtype=np.float64)
py_print_array(A, 3)

where we specify the array, the first argument to print_array, as a pointer to a Numpy array of aligned, c_contiguous 64 bit floats and the second argument as an integer which tells the C code the number of elements in the Numpy array. This then printed by the C code as follows,

1.4
2.6
3.0

You want a form that self submits? Then you just leave the "action" parameter blank.

like:

<form method="post" action="" />

If you want to process the form with this page, then make sure that you have some mechanism in the form or session data to test whether it was properly submitted and to ensure you're not trying to process the empty form.

You might want another mechanism to decide if the form was filled out and submitted but is invalid. I usually use a hidden input field that matches a session variable to decide whether the user has clicked submit or just loaded the page for the first time. By giving a unique value each time and setting the session data to the same value, you can also avoid duplicate submissions if the user clicks submit twice.

This code also works:

this.formGroup.controls.nameOfcontrol.value

must please see guys that the error is in the cv2.imread() .Give the right path of the image. and firstly, see if your system loads the image or not. this can be checked first by simple load of image using cv2.imread(). after that ,see this code for the face detection

import numpy as np
import cv2

cascPath = "/Users/mayurgupta/opt/anaconda3/lib/python3.7/site-   packages/cv2/data/haarcascade_frontalface_default.xml"

eyePath = "/Users/mayurgupta/opt/anaconda3/lib/python3.7/site-packages/cv2/data/haarcascade_eye.xml"

smilePath = "/Users/mayurgupta/opt/anaconda3/lib/python3.7/site-packages/cv2/data/haarcascade_smile.xml"

face_cascade = cv2.CascadeClassifier(cascPath)
eye_cascade = cv2.CascadeClassifier(eyePath)
smile_cascade = cv2.CascadeClassifier(smilePath)

img = cv2.imread('WhatsApp Image 2020-04-04 at 8.43.18 PM.jpeg')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

faces = face_cascade.detectMultiScale(gray, 1.3, 5)
for (x,y,w,h) in faces:
    img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
    roi_gray = gray[y:y+h, x:x+w]
    roi_color = img[y:y+h, x:x+w]
    eyes = eye_cascade.detectMultiScale(roi_gray)
    for (ex,ey,ew,eh) in eyes:
        cv2.rectangle(roi_color,(ex,ey),(ex+ew,ey+eh),(0,255,0),2)

cv2.imshow('img',img)
cv2.waitKey(0)
cv2.destroyAllWindows()

Here, cascPath ,eyePath ,smilePath should have the right actual path that's picked up from lib/python3.7/site-packages/cv2/data here this path should be to picked up the haarcascade files

As several others have said, you want to use Convert.ChangeType:

propertyInfo.SetValue(ship,
    Convert.ChangeType(value, propertyInfo.PropertyType),
    null);

In fact, I recommend you look at the entire Convert Class.

This class, and many other useful classes are part of the System Namespace. I find it useful to scan that namespace every year or so to see what features I've missed. Give it a try!

The simplest is to do a PivotChart. Select your array of dates (with a header) and create a new Pivot Chart (Insert / PivotChart / Ok) Then on the field list window, drag and drop the date column in the Axis list first and then in the value list first.

Step 1:

Step 2:

You have to use HorizontalContentAlignment="Center" and! Width="Auto".

Git automatically colors most of its output if you ask it to. You can get very specific about what you want colored and how; but to turn on all the default terminal coloring, set color.ui to true:

git config --global color.ui true

Perform the operation inside the scope itself.

<script>
angular.controller('MyCtrl', function($scope, $window) {
$scope.num1= 0;
$scope.num2= 1;


  $scope.total = $scope.num1 + $scope.num2;

 });

Use javascript array push() method, it adds the given object in the end of the array. JS Arrays are pretty flexible,you can push as many objects as you wish in an array without specifying its length beforehand. Also,different types of objects can be pushed to the same Array.

In my understanding you want to match a non-blank and non-empty string, so the top answer is doing the opposite. I suggest:

(.|\s)*\S(.|\s)*

- this matches any string containing at least one non-whitespace character (the \S in the middle). It can be preceded and followed by anything, any char or whitespace sequence (including new lines) - (.|\s)*.

You can try it with explanation on https://regex101.com/.

If whichView is an object of the GuideView Enum, following works well. Please note that there is no qualifier for the constant after case.

switch (whichView) {
    case SEVEN_DAY:
        ...
        break;
    case NOW_SHOWING:
        ...
        break;
}

According to Rails guide, this one liner should be used because it would load from the schema.rb instead of reloading the migration files one by one:

rake db:reset

If you declare a class in module file instead of the simple object

File: UserModule.js

//User Module    
class User {
  constructor(){
    //enter code here
  }
  create(params){
    //enter code here
  }
}
class UserInfo {
  constructor(){
    //enter code here
  }
  getUser(userId){
    //enter code here
    return user;
  }
}

// export multi
module.exports = [User, UserInfo];

Main File: index.js

// import module like
const { User, UserInfo } = require("./path/to/UserModule");
User.create(params);
UserInfo.getUser(userId);

Try this (LINQ method syntax):

string[] columnNames = dt.Columns.Cast<DataColumn>()
                                 .Select(x => x.ColumnName)
                                 .ToArray();  

or in LINQ Query syntax:

string[] columnNames = (from dc in dt.Columns.Cast<DataColumn>()
                        select dc.ColumnName).ToArray();

Cast is required, because Columns is of type DataColumnCollection which is a IEnumerable, not IEnumerable<DataColumn>. The other parts should be obvious.

Based on my experience, solution which is fine(the best) when keys are not important:

$cart = [];
$cart[] = 13;
$cart[] = "foo";
$cart[] = obj;

You have to wait until the browser knows the duration of the video before you can seek to a particular time. So, I think you want to wait for the 'loadedmetadata' event something like this:

document.getElementById('vid1').addEventListener('loadedmetadata', function() {
  this.currentTime = 50;
}, false);

It also worth noting that Concat works in constant time and in constant memory. For example, the following code

        long boundary = 60000000;
        for (long i = 0; i < boundary; i++)
        {
            list1.Add(i);
            list2.Add(i);
        }
        var listConcat = list1.Concat(list2);
        var list = listConcat.ToList();
        list1.AddRange(list2);

gives the following timing/memory metrics:

After lists filled mem used: 1048730 KB
concat two enumerables: 00:00:00.0023309 mem used: 1048730 KB
convert concat to list: 00:00:03.7430633 mem used: 2097307 KB
list1.AddRange(list2) : 00:00:00.8439870 mem used: 2621595 KB

Unfortunately, there is no simple way in SQL Server 2005. Lukasz' answer is correct for SQL Server 2008 though and the feature is long overdue

Any solution would involve temp tables, or passing in xml/CSV and parsing in the UDF. Example: change to xml, parse in udf

DECLARE @psuedotable xml

SELECT
    @psuedotable = ...
FROM
    ...
FOR XML ...

SELECT ... dbo.MyUDF (@psuedotable)

What do you want to do in the bigger picture though? There may be another way to do this...

Edit: Why not pass in the query as a string and use a stored proc with output parameter

Note: this is an untested bit of code, and you'd need to think about SQL injection etc. However, it also satisfies your "one column" requirement and should help you along

CREATE PROC dbo.ToCSV (
    @MyQuery varchar(2000),
    @CSVOut varchar(max)
)
AS
SET NOCOUNT ON

CREATE TABLE #foo (bar varchar(max))

INSERT #foo
EXEC (@MyQuery)

SELECT
    @CSVOut = SUBSTRING(buzz, 2, 2000000000)
FROM
    (
    SELECT 
        bar -- maybe CAST(bar AS varchar(max))??
    FROM 
        #foo
    FOR XML PATH (',')
    ) fizz(buzz)
GO

I've used CSS Grid to fix that. CSS Grid will make all the elements in the same row, all the same height.

I haven't looked into making all the elements in all the rows the same height though.

Anyway, here's how it can be done:

HTML:

<div class="grid-container">

  <div class="card">...</div>
  <div class="card">...</div>
</div>

CSS:

.grid-container {
  display: grid;  
  grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
}

dbSolo, it is paid but this feature might be the one you are looking for http://www.dbsolo.com/help/compare.html

It works with Oracle, Microsoft SQL Server, Sybase, DB2, Solid, PostgreSQL, H2 and MySQL

Imagine you are developing a web-application and you decide to decouple the functionality from the presentation of the application, because it affords greater freedom.

You create an API and let others implement their own front-ends over it as well. What you just did here is implement an SOA methodology, i.e. using web-services.

Web services make functional building-blocks accessible over standard Internet protocols independent of platforms and programming languages.

So, you design an interchange mechanism between the back-end (web-service) that does the processing and generation of something useful, and the front-end (which consumes the data), which could be anything. (A web, mobile, or desktop application, or another web-service). The only limitation here is that the front-end and back-end must "speak" the same "language".

That's where SOAP and REST come in. They are standard ways you'd pick communicate with the web-service.

SOAP:

SOAP internally uses XML to send data back and forth. SOAP messages have rigid structure and the response XML then needs to be parsed. WSDL is a specification of what requests can be made, with which parameters, and what they will return. It is a complete specification of your API.

REST:

REST is a design concept.

The World Wide Web represents the largest implementation of a system conforming to the REST architectural style.

It isn't as rigid as SOAP. RESTful web-services use standard URIs and methods to make calls to the webservice. When you request a URI, it returns the representation of an object, that you can then perform operations upon (e.g. GET, PUT, POST, DELETE). You are not limited to picking XML to represent data, you could pick anything really (JSON included)

Flickr's REST API goes further and lets you return images as well.

JSON and XML, are functionally equivalent, and common choices. There are also RPC-based frameworks like GRPC based on Protobufs, and Apache Thrift that can be used for communication between the API producers and consumers. The most common format used by web APIs is JSON because of it is easy to use and parse in every language.

I've written a library to handle this for me. It's called DataTableProxy and is available as a NuGet package. Code and documentation is on Github

When you read the string from the GUI control, it is already a "raw" string. If you print out the string you might see the backslashes doubled up, but that's an artifact of how Python displays strings; internally there's still only a single backslash.

>>> a='\nu + \lambda + \theta'
>>> a
'\nu + \\lambda + \theta'
>>> len(a)
20
>>> b=r'\nu + \lambda + \theta'
>>> b
'\\nu + \\lambda + \\theta'
>>> len(b)
22
>>> b[0]
'\\'
>>> print b
\nu + \lambda + \theta

I encountered with this error and just decrease gradle version and android plugin version to 5.1.1 and 3.4.2.

Just remove/comment the following line from your httpd.conf file (etc/httpd/conf)

Require all granted

This is needed till Apache Version 2.2 and is not required from thereon.

Don't define variables in headers. Put declarations in header and definitions in one of the .c files.

In config.h

extern const char *names[];

In some .c file:

const char *names[] =
    {
        "brian", "stefan", "steve"
    };

If you put a definition of a global variable in a header file, then this definition will go to every .c file that includes this header, and you will get multiple definition error because a varible may be declared multiple times but can be defined only once.

They are often used interchangeably in text, but in most standards the distinction is that an argument is an expression passed to a function, where a parameter is a reference declared in a function declaration.

Your ComboBox is trying to bind to bind to GridItem[x].CompanyItems, which doesn't exist.

Your RelativeBinding is close, however it needs to bind to DataContext.CompanyItems because Window.CompanyItems does not exist

PHP uses weak typing (which it calls 'type juggling'), which is a bad idea (though that's a conversation for another time). When you try to use a variable in a context that requires a boolean, it will convert whatever your variable is into a boolean, according to some mostly arbitrary rules available here: http://www.php.net/manual/en/language.types.boolean.php#language.types.boolean.casting

Another one with an SVG as inline overlay-image (note: if you use # inside the svg-code you have to urlencode that!):

background: url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1 1"><path fill="rgba(255, 255, 255, 0.4)" d="M0 0h1v1H0z"/></svg>')
                no-repeat center center/cover, 
            url('overlayed-image.jpg') no-repeat center center/cover;

I Did that and it works for redirecting to other view I think If you add the #sectionLink after It will work

<a class="btn yellow" href="/users/Create/@Model.Id" target="_blank">
                                        Add As User
                                    </a>

This is most likely not an answer to the issue itself but this question pops up as first result when searching for Sql declare scalar variable hence i share a possible solution to this error.

In my case this error was caused by the use of ; after a SQL statement. Just remove it and the error will be gone.

I guess the cause is the same as @IronSean already posted in an comment above:

it's worth noting that using GO (or in this case ;) causes a new branch where declared variables aren't visible past the statement.

For example:

DECLARE @id int
SET @id = 78

SELECT * FROM MyTable WHERE Id = @var; <-- remove this character to avoid the error message
SELECT * FROM AnotherTable WHERE MyTableId = @var

This code simply worked for me

System.setProperty("webdriver.firefox.bin", "C:\\Program Files\\Mozilla Firefox 54\\firefox.exe");
String Firefoxdriverpath = "C:\\Users\\Hp\\Downloads\\geckodriver-v0.18.0-win64\\geckodriver.exe";
System.setProperty("webdriver.gecko.driver", Firefoxdriverpath);
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
driver = new FirefoxDriver(capabilities);

It's possible, but it requires using dynamic SQL.
I recommend reading The curse and blessings of dynamic SQL before continuing...

DECLARE @theDate varchar(60)
SET @theDate = '''2010-01-01'' AND ''2010-08-31 23:59:59'''

DECLARE @SQL VARCHAR(MAX)  
SET @SQL = 'SELECT AdministratorCode, 
                   SUM(Total) as theTotal, 
                   SUM(WOD.Quantity) as theQty, 
                   AVG(Total) as avgTotal, 
                  (SELECT SUM(tblWOD.Amount)
                     FROM tblWOD
                     JOIN tblWO on tblWOD.OrderID = tblWO.ID
                    WHERE tblWO.Approved = ''1''
                      AND tblWO.AdministratorCode = tblWO.AdministratorCode
                      AND tblWO.OrderDate BETWEEN '+ @theDate +')'

EXEC(@SQL)

Dynamic SQL is just a SQL statement, composed as a string before being executed. So the usual string concatenation occurs. Dynamic SQL is required whenever you want to do something in SQL syntax that isn't allowed, like:

• a single parameter to represent comma separated list of values for an IN clause
• a variable to represent both value and SQL syntax (IE: the example you provided)

EXEC sp_executesql allows you to use bind/preparedstatement parameters so you don't have to concern yourself with escaping single quotes/etc for SQL injection attacks.

If you don't have an existing local branch, it is truly as simple as:

git fetch
git checkout <remote-branch-name>

For instance if you fetch and there is a new remote tracking branch called origin/feature/Main_Page, just do this:

git checkout feature/Main_Page

This creates a local branch with the same name as the remote branch, tracking that remote branch. If you have multiple remotes with the same branch name, you can use the less ambiguous:

git checkout -t <remote>/<remote-branch-name>

If you already made the local branch and don't want to delete it, see How do you make an existing Git branch track a remote branch?.

Actually, just before FF3 was out, I did some experiments, and FF2 sends only the filename, like did Opera 9.0. Only IE sends the full path. The behavior makes sense, because the server doesn't have to know where the user stores the file on his computer, it is irrelevant to the upload process. Unless you are writing an intranet application and get the file by direct network access!

What have changed (and that's the real point of the bug item you point to) is that FF3 no longer let access to the file path from JavaScript. And won't let type/paste a path there, which is more annoying for me: I have a shell extension which copies the path of a file from Windows Explorer to the clipboard and I used it a lot in such form. I solved the issue by using the DragDropUpload extension. But this becomes off-topic, I fear.

I wonder what your Web forms are doing to stop working with this new behavior.

[EDIT] After reading the page linked by Mike, I see indeed intranet uses of the path (identify a user for example) and local uses (show preview of an image, local management of files). User Jam-es seems to provide a workaround with nsIDOMFile (not tried yet).

A variable is just a label pointing to an object. The object is immutable, but you can make the label point to a completely different object if you want to.

I switched to a different USB port and it suddenly got recognized...

Another choice besides JObject is System.Json.JsonValue for Weak-Typed JSON object.

It also has a JsonValue blob = JsonValue.Parse(json); you can use. The blob will most likely be of type JsonObject which is derived from JsonValue, but could be JsonArray. Check the blob.JsonType if you need to know.

And to answer you question, YES, you may replace json with the name of your actual variable that holds the JSON string. ;-D

There is a System.Json.dll you should add to your project References.

You should use the grep -q flag for quiet output. See the man pages below:

man grep output :

 General Output Control

  -q, --quiet, --silent
              Quiet;  do  not write anything to standard output.  Exit immediately with zero status
              if any match is  found,  even  if  an  error  was  detected.   Also  see  the  -s  or
              --no-messages option.  (-q is specified by POSIX.)

This KornShell (ksh) script demos the grep quiet output and is a solution to your question.

I had the same issue and while user1732055's answer fixes the border, it removes the dropdown arrows. I solved this by removing the border from the select element and creating a wrapper span which has a border.

html:

<span class="select-wrapper">
    <select class="form-control no-radius">
        <option value="1">1</option>
        <option value="2">2</option>
        <option value="3">3</option>
    </select>
</span>

css:

select.no-radius{
    border:none;
}    
.select-wrapper{
    border: 1px solid black;
    border-radius: 0px;
}

Sometimes, when I know that I am working with numbers, I use this logic (if result is not greater than zero):

if (!$result['column']>0){

}

I have same problem while importing database from linux to Windows. It lowercases Database name aswell as Tables' name. Use following steps for same problem:

1. Open c:\xampp\mysql\bin\my.ini in editor.
2. look for

# The MySQL server

[mysqld]

3 . Find

lower_case_table_names

and change value to 2

if not avail copy this at the end of this [mysqld] portion.

lower_case_table_names = 2

This will surely work.

For the error 5, i did the opposite to the solution above. "The first Error 5: Access Denied error was resolved by giving permissions to the output directory to the NETWORK SERVICE account."

I changed mine to local account, instead of network service account, and because i was logged in as administrator it worked

It shouldn't be your call to decide whether the link should open in a new tab or a new window, since ultimately this choice should be done by the settings of the user's browser. Some people like tabs; some like new windows.

Using _blank will tell the browser to use a new tab/window, depending on the user's browser configuration and how they click on the link (e.g. middle click, Ctrl+click, or normal click).

function checkChange($this){
    var value = $this.val();      
    var sv=$this.data("stored");            
        if(value!=sv)
            $this.trigger("simpleChange");    
}

$(document).ready(function(){
    $(this).data("stored",$(this).val());   
        $("input").bind("keyup",function(e){  
        checkChange($(this));
    });        
    $("input").bind("simpleChange",function(e){
        alert("the value is chaneged");
    });        
});

I found out that re-installing Xampp as an administrator and running it as an Administrator worked.

You alread removed the active class from all the tabs but then you add the active class, again, to all the tabs. You should only add the active class to the currently selected tab like so http://jsfiddle.net/QFnRa/

$(".tab").removeClass("active");
$(this).addClass("active");  

Take a look at the Cursor.Position Property. It should get you started.

private void MoveCursor()
{
   // Set the Current cursor, move the cursor's Position,
   // and set its clipping rectangle to the form. 

   this.Cursor = new Cursor(Cursor.Current.Handle);
   Cursor.Position = new Point(Cursor.Position.X - 50, Cursor.Position.Y - 50);
   Cursor.Clip = new Rectangle(this.Location, this.Size);
}

1. You missed the order, first goes:

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/1.0.18/vue.min.js"></script>

and then:

    var demo = new Vue({
        el: '#demo',
        data: {
            message: 'Hello Vue.js!'

To solve this problem I had to install the package with the missing system image using SDK Manager.exe (in "C:\Program Files (x86)\Android\android-sdk"). I had noticed that the system image I needed ("android-23") was missing in "C:\Program Files (x86)\Android\android-sdk\system-images".

After running SDK Manager.exe and installing the appropriate packages I could run the emulator in Android Studio.

Here's the solution that worked for me:

Regardless to Your example

select length('Burger') from dual;

I hope this will help :)

It works, but I wouldn't do it if I were you. You don't seem to be deleting that heap data when you're done, which means that you've created a memory leak. The C++ compiler takes care of ensuring that exception data is kept alive even as the stack is popped, so don't feel that you need to use the heap.

Incidentally, throwing a std::string isn't the best approach to begin with. You'll have a lot more flexibility down the road if you use a simple wrapper object. It may just encapsulate a string for now, but maybe in future you will want to include other information, like some data which caused the exception or maybe a line number (very common, that). You don't want to change all of your exception handling in every spot in your code-base, so take the high road now and don't throw raw objects.

You can use ymd from lubridate

lubridate::ymd(v)
#[1] "2008-11-01"

Or anytime::anydate

anytime::anydate(v)
#[1] "2008-11-01"

You could try to use the following function

def tableIt(data):
    for lin in data:
        print("+---"*len(lin)+"+")
        for inlin in lin:
            print("|",str(inlin),"", end="")
        print("|")
    print("+---"*len(lin)+"+")

data = [[1,2,3,2,3],[1,2,3,2,3],[1,2,3,2,3],[1,2,3,2,3]]

tableIt(data)
