Pattern class is the entry point of the regex engine.You can use it through Pattern.matches() and Pattern.comiple(). #Difference between these two. matches()- for quickly check if a text (String) matches a given regular expression comiple()- create the reference of Pattern. So can use multiple times to match the regular expression against multiple texts.

For reference:

public static void main(String[] args) {
     //single time uses
     String text="The Moon is far away from the Earth";
     String pattern = ".*is.*";
     boolean matches=Pattern.matches(pattern,text);
     System.out.println("Matches::"+matches);

    //multiple time uses
     Pattern p= Pattern.compile("ab");
     Matcher  m=p.matcher("abaaaba");
     while(m.find()) {
         System.out.println(m.start()+ " ");
     }
}

There is no defined maximum size for HTTP POST requests. If you notice such a limit then it's an arbitrary limitation of your HTTP Server/Client.

You might get a better answer if you tell how big the XML is.

It is simple, as a java, Android also supporting singleton. -

Singleton is a part of Gang of Four design pattern and it is categorized under creational design patterns.

-> Static member : This contains the instance of the singleton class.

-> Private constructor : This will prevent anybody else to instantiate the Singleton class.

-> Static public method : This provides the global point of access to the Singleton object and returns the instance to the client calling class.

1. create private instance
2. create private constructor

3. use getInstance() of Singleton class

   public class Logger{
   private static Logger   objLogger;
   private Logger(){
   
           //ToDo here
   
   }
   public static Logger getInstance()
   {
       if (objLogger == null)
      {
         objLogger = new Logger();
      }
      return objLogger;
      }
   
   }
   

while use singleton -

Logger.getInstance();

1. Open Oracle VM VirtualBox Manager
2. Select the VM used by Docker
3. Click Settings -> Network
4. Adapter 1 should (default?) be "Attached to: NAT"
5. Click Advanced -> Port Forwarding
6. Add rule: Protocol TCP, Host Port 8080, Guest Port 8080 (leave Host IP and Guest IP empty)
7. Guest is your docker container and Host is your machine

You should now be able to browse to your container via localhost:8080 and your-internal-ip:8080.

Maybe your class isn't quite complete. Personally, I use a private init() function with all of my overloaded constructors.

class Point2D {

  double X, Y;

  public Point2D(double x, double y) {
    init(x, y);
  }

  public Point2D(Point2D point) {
    if (point == null)
      throw new ArgumentNullException("point");
    init(point.X, point.Y);
  }

  void init(double x, double y) {
    // ... Contracts ...
    X = x;
    Y = y;
  }
}

Answer for Newer Versions of Windows

Today, I posted some code on another question and an explanation of how to do this with IsWow64Process2 for Windows 10 version 1511 or later and Windows Server 2016. Additionally, the code determines if the process is 32 or 64 bit and whether the process is running under the WOW64 emulator.

One of the main reasons I have posted the answer is because while there were several suggestions to use IsWow64Process2, no code that I saw showed how.

Please see the answer here: https://stackoverflow.com/a/59377888/1691559

You get this error because one of your variables is actually a factor variable . Execute

str(df) 

to check this. Then do this double variable change to keep the year numbers instead of transforming into "1,2,3,4" level numbers:

df$year <- as.numeric(as.character(df$year))

EDIT: it appears that your data.frame has a variable of class "array" which might cause the pb. Try then:

df <- data.frame(apply(df, 2, unclass))

and plot again?

They do not do the same thing. The latter printf statement interprets b as an unsigned int, which is wrong, as b is a pointer.

Pointers and unsigned ints are not always the same size, so these are not interchangeable. When they aren't the same size (an increasingly common case, as 64-bit CPUs and operating systems become more common), %x will only print half of the address. On a Mac (and probably some other systems), that will ruin the address; the output will be wrong.

Always use %p for pointers.

    for(i=1 ;i<=n;i++) {

        let str = ' '.repeat(n-i);
        let str2 = '*'.repeat(i*2-1);
    console.log(str + str2 + str);

}

I stopped writing this myself for laravel in favor of the Laracasts package that handles it all for you. It is really easy to use and keeps your code clean. There is even a laracast that covers how to use it. All you have to do:

Pull in the package through Composer.

"require": {
  "laracasts/flash": "~1.0"
}

Include the service provider within app/config/app.php.

'providers' => [
  'Laracasts\Flash\FlashServiceProvider'
];

Add a facade alias to this same file at the bottom:

'aliases' => [
  'Flash' => 'Laracasts\Flash\Flash'
];

Pull the HTML into the view:

@include('flash::message') 

There is a close button on the right of the message. This relies on jQuery so make sure that is added before your bootstrap.

optional changes:

If you aren't using bootstrap or want to skip the include of the flash message and write the code yourself:

@if (Session::has('flash_notification.message'))
  <div class="{{ Session::get('flash_notification.level') }}">
    {{ Session::get('flash_notification.message') }}
  </div>
@endif

If you would like to view the HTML pulled in by @include('flash::message'), you can find it in vendor/laracasts/flash/src/views/message.blade.php.

If you need to modify the partials do:

php artisan view:publish laracasts/flash

The two package views will now be located in the `app/views/packages/laracasts/flash/' directory.

I recently created a library for creating Gson objects fluently:

http://jglue.org/fluent-json/

It works like this:

  JsonObject jsonObject = JsonBuilderFactory.buildObject() //Create a new builder for an object
  .addNull("nullKey")                            //1. Add a null to the object

  .add("stringKey", "Hello")                     //2. Add a string to the object
  .add("stringNullKey", (String) null)           //3. Add a null string to the object

  .add("numberKey", 2)                           //4. Add a number to the object
  .add("numberNullKey", (Float) null)            //5. Add a null number to the object

  .add("booleanKey", true)                       //6. Add a boolean to the object
  .add("booleanNullKey", (Boolean) null)         //7. Add a null boolean to the object

  .add("characterKey", 'c')                      //8. Add a character to the object
  .add("characterNullKey", (Character) null)     //9. Add a null character to the object

  .addObject("objKey")                           //10. Add a nested object
    .add("nestedPropertyKey", 4)                 //11. Add a nested property to the nested object
    .end()                                       //12. End nested object and return to the parent builder

  .addArray("arrayKey")                          //13. Add an array to the object
    .addObject()                                 //14. Add a nested object to the array
      .end()                                     //15. End the nested object
    .add("arrayElement")                         //16. Add a string to the array
    .end()                                       //17. End the array

    .getJson();                                  //Get the JsonObject

String json = jsonObject.toString();

And through the magic of generics it generates compile errors if you try to add an element to an array with a property key or an element to an object without a property name:

JsonObject jsonArray = JsonBuilderFactory.buildArray().addObject().end().add("foo", "bar").getJson(); //Error: tried to add a string with property key to array.
JsonObject jsonObject = JsonBuilderFactory.buildObject().addArray().end().add("foo").getJson(); //Error: tried to add a string without property key to an object.
JsonArray jsonArray = JsonBuilderFactory.buildObject().addArray("foo").getJson(); //Error: tried to assign an object to an array.
JsonObject jsonObject = JsonBuilderFactory.buildArray().addObject().getJson(); //Error: tried to assign an object to an array.

Lastly there is mapping support in the API which allows you to map your domain objects to JSON. The goal being when Java8 is released you'll be able to do something like this:

Collection<User> users = ...;
JsonArray jsonArray = JsonBuilderFactory.buildArray(users, { u-> buildObject()
                                                                 .add("userName", u.getName())
                                                                 .add("ageInYears", u.getAge()) })
                                                                 .getJson();

How about using good(?) old goto?

:loop

echo Ooops

goto loop

See also this for a more useful example.

You need $route defined in your module and change the JS to this.

$scope.backLinkClick = function () {
  window.location.reload(); 
};

that works fine for me.

Ajax Submit form with out page refresh by using jquery ajax method first include library jquery.js and jquery-form.js then create form in html:

<form action="postpage.php" method="POST" id="postForm" >

<div id="flash_success"></div>

name:
<input type="text" name="name" />
password:
<input type="password" name="pass" />
Email:
<input type="text" name="email" />

<input type="submit" name="btn" value="Submit" />
</form>

<script>
  var options = { 
        target:        '#flash_success',  // your response show in this ID
        beforeSubmit:  callValidationFunction,
        success:       YourResponseFunction  
    };
    // bind to the form's submit event
        jQuery('#postForm').submit(function() { 
            jQuery(this).ajaxSubmit(options); 
            return false; 
        }); 


});
function callValidationFunction()
{
 //  validation code for your form HERE
}

function YourResponseFunction(responseText, statusText, xhr, $form)
{
    if(responseText=='success')
    {
        $('#flash_success').html('Your Success Message Here!!!');
        $('body,html').animate({scrollTop: 0}, 800);

    }else
    {
        $('#flash_success').html('Error Msg Here');

    }
}
</script>

Circular imports can be confusing because import does two things:

1. it executes imported module code
2. adds imported module to importing module global symbol table

The former is done only once, while the latter at each import statement. Circular import creates situation when importing module uses imported one with partially executed code. In consequence it will not see objects created after import statement. Below code sample demonstrates it.

Circular imports are not the ultimate evil to be avoided at all cost. In some frameworks like Flask they are quite natural and tweaking your code to eliminate them does not make the code better.

main.py

print 'import b'
import b
print 'a in globals() {}'.format('a' in globals())
print 'import a'
import a
print 'a in globals() {}'.format('a' in globals())
if __name__ == '__main__':
    print 'imports done'
    print 'b has y {}, a is b.a {}'.format(hasattr(b, 'y'), a is b.a)

b.by

print "b in, __name__ = {}".format(__name__)
x = 3
print 'b imports a'
import a
y = 5
print "b out"

a.py

print 'a in, __name__ = {}'.format(__name__)
print 'a imports b'
import b
print 'b has x {}'.format(hasattr(b, 'x'))
print 'b has y {}'.format(hasattr(b, 'y'))
print "a out"

python main.py output with comments

import b
b in, __name__ = b    # b code execution started
b imports a
a in, __name__ = a    # a code execution started
a imports b           # b code execution is already in progress
b has x True
b has y False         # b defines y after a import,
a out
b out
a in globals() False  # import only adds a to main global symbol table 
import a
a in globals() True
imports done
b has y True, a is b.a True # all b objects are available

All fine, but this should also work from env:

PROCESSOR_ARCHITECTURE=x86

..

PROCESSOR_ARCHITECTURE=AMD64

Too easy, maybe ;-)

I was facing the same issue because I was using Lombok @Data annotation that was creating toString and hashcode methods in class files, so I removed @Data annotation and used specific @Gettter @Setter annotation that fixed my issue.

we should use @Data only when we need all @ToString, @EqualsAndHashCode, @Getter on all fields, and @Setter on all non-final fields, and @RequiredArgsConstructor.

It is a simple 3 Step Process :
1) Go to your private repo and click on settings
2) To the left of the screen click on Manage access
3) Then Click on Invite Collaborator

In my experience, tests of the form if (ptr) or if (!ptr) are preferred. They do not depend on the definition of the symbol NULL. They do not expose the opportunity for the accidental assignment. And they are clear and succinct.

Edit: As SoapBox points out in a comment, they are compatible with C++ classes such as auto_ptr that are objects that act as pointers and which provide a conversion to bool to enable exactly this idiom. For these objects, an explicit comparison to NULL would have to invoke a conversion to pointer which may have other semantic side effects or be more expensive than the simple existence check that the bool conversion implies.

I have a preference for code that says what it means without unneeded text. if (ptr != NULL) has the same meaning as if (ptr) but at the cost of redundant specificity. The next logical thing is to write if ((ptr != NULL) == TRUE) and that way lies madness. The C language is clear that a boolean tested by if, while or the like has a specific meaning of non-zero value is true and zero is false. Redundancy does not make it clearer.

composer run post-root-package-install or sudo composer run post-root-package-install

Thoughts (based on pain in the past):

• do you have DNS and line-of-sight to the server?
• are you using the correct name from the certificate?
• is the certificate still valid?
• is a badly configured load balancer messing things up?
• does the new server machine have the clock set correctly (i.e. so that the UTC time is correct [ignore local time, it is largely irrelevent]) - this certainly matters for WCF, so may impact regular SOAP?
• is there a certificate trust chain issue? if you browse from the server to the soap service, can you get SSL?
• related to the above - has the certificate been installed to the correct location? (you may need a copy in Trusted Root Certification Authorities)
• is the server's machine-level proxy set correctly? (which different to the user's proxy); see proxycfg for XP / 2003 (not sure about Vista etc)

Why the prohibition "I don't want to use any looping"? That's the most obvious solution. When given the chance to be obvious, take it!

Note that calls like arr.Contains(...) are still going to loop, it just won't be you who has written the loop.

Have you considered an alternate representation that's more amenable to searching?

• A good Set implementation would perform well. (HashSet, TreeSet or the local equivalent).
• If you can be sure that arr is sorted, you could use binary search (which would need to recurse or loop, but not as often as a straight linear search).

Each group defined by parenthesis () is captured during processing and each captured group content is pushed into result array in same order as groups within pattern starts. See more on http://www.regular-expressions.info/brackets.html and http://www.regular-expressions.info/refcapture.html (choose right language to see supported features)

var source = "afskfsd33j"
var result = source.match(/a(.*)j/);

result: ["afskfsd33j", "fskfsd33"]

The reason why you received this exact result is following:

First value in array is the first found string which confirms the entire pattern. So it should definitely start with "a" followed by any number of any characters and ends with first "j" char after starting "a".

Second value in array is captured group defined by parenthesis. In your case group contain entire pattern match without content defined outside parenthesis, so exactly "fskfsd33".

If you want to get rid of second value in array you may define pattern like this:

/a(?:.*)j/

where "?:" means that group of chars which match the content in parenthesis will not be part of resulting array.

Other options might be in this simple case to write pattern without any group because it is not necessary to use group at all:

/a.*j/

If you want to just check whether source text matches the pattern and does not care about which text it found than you may try:

var result = /a.*j/.test(source);

The result should return then only true|false values. For more info see http://www.javascriptkit.com/javatutors/re3.shtml

Although other answers include some of the following information, this is the absolute minimum that needs to be changed on EC2 instances, specifically regarding deployment of large WAR files, and is the least likely to cause issues during future updates. I've been running into these limits about every other year due to the ever-increasing size of the Jenkins WAR file (now ~72MB).

More specifically, this answer is applicable if you encounter a variant of the following error in catalina.out:

SEVERE [https-jsse-nio-8443-exec-17] org.apache.catalina.core.ApplicationContext.log HTMLManager:
FAIL - Deploy Upload Failed, Exception:
[org.apache.tomcat.util.http.fileupload.FileUploadBase$SizeLimitExceededException:
the request was rejected because its size (75333656) exceeds the configured maximum (52428800)]

On Amazon EC2 Linux instances, the only file that needs to be modified from the default installation of Tomcat (sudo yum install tomcat8) is:

/usr/share/tomcat8/webapps/manager/WEB-INF/web.xml

By default, the maximum upload size is exactly 50MB:

<multipart-config>
  <!-- 50MB max -->
  <max-file-size>52428800</max-file-size>
  <max-request-size>52428800</max-request-size>
  <file-size-threshold>0</file-size-threshold>
</multipart-config>

There are only two values that need to be modified (max-file-size and max-request-size):

<multipart-config>
  <!-- 100MB max -->
  <max-file-size>104857600</max-file-size>
  <max-request-size>104857600</max-request-size>
  <file-size-threshold>0</file-size-threshold>
</multipart-config>

When Tomcat is upgraded on these instances, the new version of the manager web.xml will be placed in web.xml.rpmnew, so any modifications to the original file will not be overwritten during future updates.

Angular comes with a limitTo:limit filter, it support limiting first x items and last x items:

<div ng-repeat="item in items|limitTo:4">{{item}}</div>

I didn't use JSP but I had similar error when I was setting response to return JSON object by calling PrintWriter's flush() method or return statement. Previous answer i.e wrapping return-statement into a try-block worked kind of: the error disappeared because return-statement makes method to ignore all code below try-catch, specifically in my case, line redirectStrategy.sendRedirect(request, response, destination_addr_string) which seem to modify the already committed response that causes the error. The simpler solution in my case was just to remove the line and let client app to take care of the redirection.

I don't think that you should be using an array to maintain tokens. Neither you need a guid as a token.

You can easily use context.SerializeTicket().

See my below code.

public class RefreshTokenProvider : IAuthenticationTokenProvider
{
    public async Task CreateAsync(AuthenticationTokenCreateContext context)
    {
        Create(context);
    }

    public async Task ReceiveAsync(AuthenticationTokenReceiveContext context)
    {
        Receive(context);
    }

    public void Create(AuthenticationTokenCreateContext context)
    {
        object inputs;
        context.OwinContext.Environment.TryGetValue("Microsoft.Owin.Form#collection", out inputs);

        var grantType = ((FormCollection)inputs)?.GetValues("grant_type");

        var grant = grantType.FirstOrDefault();

        if (grant == null || grant.Equals("refresh_token")) return;

        context.Ticket.Properties.ExpiresUtc = DateTime.UtcNow.AddDays(Constants.RefreshTokenExpiryInDays);

        context.SetToken(context.SerializeTicket());
    }

    public void Receive(AuthenticationTokenReceiveContext context)
    {
        context.DeserializeTicket(context.Token);

        if (context.Ticket == null)
        {
            context.Response.StatusCode = 400;
            context.Response.ContentType = "application/json";
            context.Response.ReasonPhrase = "invalid token";
            return;
        }

        if (context.Ticket.Properties.ExpiresUtc <= DateTime.UtcNow)
        {
            context.Response.StatusCode = 401;
            context.Response.ContentType = "application/json";
            context.Response.ReasonPhrase = "unauthorized";
            return;
        }

        context.Ticket.Properties.ExpiresUtc = DateTime.UtcNow.AddDays(Constants.RefreshTokenExpiryInDays);
        context.SetTicket(context.Ticket);
    }
}

Instant stop = 
    myUtilDateStart.toInstant()
                   .plus( Duration.ofMinutes( x ) ) 
;

java.time

Other Answers are correct, especially the Answer by Borgwardt. But those Answers use outmoded legacy classes.

The original date-time classes bundled with Java have been supplanted with java.time classes. Perform your business logic in java.time types. Convert to the old types only where needed to work with old code not yet updated to handle java.time types.

If your Calendar is actually a GregorianCalendar you can convert to a ZonedDateTime. Find new methods added to the old classes to facilitate conversion to/from java.time types.

if( myUtilCalendar instanceof GregorianCalendar ) {
    GregorianCalendar gregCal = (GregorianCalendar) myUtilCalendar; // Downcasting from the interface to the concrete class.
    ZonedDateTime zdt = gregCal.toZonedDateTime();  // Create `ZonedDateTime` with same time zone info found in the `GregorianCalendar`
end if 

If your Calendar is not a Gregorian, call toInstant to get an Instant object. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds.

Instant instant = myCal.toInstant();

Similarly, if starting with a java.util.Date object, convert to an Instant. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = myUtilDate.toInstant();

Apply a time zone to get a ZonedDateTime.

ZoneId z = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = instant.atZone( z );

To get a java.util.Date object, go through the Instant.

java.util.Date utilDate = java.util.Date.from( zdt.toInstant() );

For more discussion of converting between the legacy date-time types and java.time, and a nifty diagram, see my Answer to another Question.

Duration

Represent the span of time as a Duration object. Your input for the duration is a number of minutes as mentioned in the Question.

Duration d = Duration.ofMinutes( yourMinutesGoHere );

You can add that to the start to determine the stop.

Instant stop = startInstant.plus( d ); 

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to java.time.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

The best way to convert it to HashMap<String, Object> is this:

HashMap<String, Object> result = new ObjectMapper().readValue(jsonString, new TypeReference<Map<String, Object>>(){}));

This works:

var img = document.createElement('img');
img.src = 'img/eqp/' + this.apparel + '/' + this.facing + '_idle.png';
document.getElementById('gamediv').appendChild(img)

Or using jQuery:

$('<img/>')
.attr('src','img/eqp/' + this.apparel + '/' + this.facing + '_idle.png')
.appendTo('#gamediv');

Please use below function if you don't want to round off.

function ConvertToDecimal(num) {
    num = num.toString(); //If it's not already a String
    num = num.slice(0, (num.indexOf(".")) + 3); //With 3 exposing the hundredths place
   alert('M : ' +  Number(num)); //If you need it back as a Number    
}

You can do it this way (synchronously, but compact):

UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:MyURL]]];

A much better approach is to use Apple's LazyTableImages to preserve interactivity.

This is a network problem. Check out your database connectivity. Either your database connection link, username and password is wrong or your database server is stopped.

As mentioned above, put gem: --no-document in your gem file. However, the system-wide gemrc will not always necessarily go into /etc/gemrc.

require 'rubygems'
Gem::ConfigFile::SYSTEM_WIDE_CONFIG_FILE

See the original post on this over here.

For me.

Edit .gitattributes file.

add

*.dll binary

Then everything goes well.

Looks like you can construct the link to the NDK that you want and download it from dl.google.com:

Linux example:
http://dl.google.com/android/ndk/android-ndk-r9b-linux-x86.tar.bz2 http://dl.google.com/android/ndk/android-ndk-r9b-linux-x86_64.tar.bz2

OS X example:
http://dl.google.com/android/ndk/android-ndk-r9b-darwin-x86.tar.bz2 http://dl.google.com/android/ndk/android-ndk-r9b-darwin-x86_64.tar.bz2

Windows example:
http://dl.google.com/android/ndk/android-ndk-r9b-windows.zip

Extensions up to r10b:
.tar.bz2 for linux / os x and .zip for windows.

Since r10c the extensions have changed to:
.bin for linux / os x and .exe for windows

Since r11:

.zip for linux and OS X as well, a new URL base, and no 32 bit versions for OS X and linux.

https://dl.google.com/android/repository/android-ndk-r11-linux-x86_64.zip

I used a list in my controller class to set data into grid view. The code works fine for me:

public ActionResult ExpExcl()
{
  List<PersonModel> person= new List<PersonModel>
   { 
    new PersonModel() {FirstName= "Jenny", LastName="Mathew", Age= 23},
    new PersonModel() {FirstName= "Paul", LastName="Meehan", Age=25}
   };
   var grid= new GridView();
   grid.DataSource= person;
   grid.DataBind();

   Response.ClearContent();
   Response.AddHeader("content-disposition","attachement; filename=data.xls");
   Response.ContentType="application/excel";
   StringWriter sw= new StringWriter();
   HtmlTextWriter htw= new HtmlTextWriter(sw); 
   grid.RenderControl(htw);
   Response.Output.Write(sw.ToString());
   Response.Flush();
   Response.End();
   return View();
 }

Alternatively You can use the brew or curl command for installing things, wherever apt-get is mentioned with a URL...

For example,

curl -O http://www.magentocommerce.com/downloads/assets/1.8.1.0/magento-1.8.1.0.tar.gz

If you use form.close() in your form and set the FormClosing Event of your form and either use form.close() in this Event ,you fall in unlimited loop and Argument out of range happened and the solution is that change the form.close() with form.dispose() in Event of FormClosing. I hope this little tip help you!!!

On the "How to do it" part:

I think the introduction to ScalaTest does good job of illustrating different styles of unit tests.

On the "When to do it" part:

Unit testing is not only for testing. By doing unit testing you also force the design of the software into something that is unit testable. Many people are of the opinion that this design is for the most part Good Design(TM) regardless of other benefits from testing.

So one reason to do unit test is to force your design into something that hopefully will be easier to maintain that what it would be had you not designed it for unit testing.

Rebase and Cherry-pick is the only way you can keep clean commit history. Avoid using merge and avoid creating merge conflict. If you are using gerrit set one project to Merge if necessary and one project to cherry-pick mode and try yourself.

a.getClass().getName()

Yes, it is possible to use @Transactional on private methods, but as others have mentioned this won't work out of the box. You need to use AspectJ. It took me some time to figure out how to get it working. I will share my results.

I chose to use compile-time weaving instead of load-time weaving because I think it's an overall better option. Also, I'm using Java 8 so you may need to adjust some parameters.

First, add the dependency for aspectjrt.

<dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjrt</artifactId>
    <version>1.8.8</version>
</dependency>

Then add the AspectJ plugin to do the actual bytecode weaving in Maven (this may not be a minimal example).

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>aspectj-maven-plugin</artifactId>
    <version>1.8</version>
    <configuration>
        <complianceLevel>1.8</complianceLevel>
        <source>1.8</source>
        <target>1.8</target>
        <aspectLibraries>
            <aspectLibrary>
                <groupId>org.springframework</groupId>
                <artifactId>spring-aspects</artifactId>
            </aspectLibrary>
        </aspectLibraries>
    </configuration>
    <executions>
        <execution>
            <goals>
                <goal>compile</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Finally add this to your config class

@EnableTransactionManagement(mode = AdviceMode.ASPECTJ)

Now you should be able to use @Transactional on private methods.

One caveat to this approach: You will need to configure your IDE to be aware of AspectJ otherwise if you run the app via Eclipse for example it may not work. Make sure you test against a direct Maven build as a sanity check.

My personal opinion is to use what makes sense in the context. Personally I almost never use for for array traversal. I use it for other types of iteration, but foreach is just too easy... The time difference is going to be minimal in most cases.

The big thing to watch for is:

for ($i = 0; $i < count($array); $i++) {

That's an expensive loop, since it calls count on every single iteration. So long as you're not doing that, I don't think it really matters...

As for the reference making a difference, PHP uses copy-on-write, so if you don't write to the array, there will be relatively little overhead while looping. However, if you start modifying the array within the array, that's where you'll start seeing differences between them (since one will need to copy the entire array, and the reference can just modify inline)...

As for the iterators, foreach is equivalent to:

$it->rewind();
while ($it->valid()) {
    $key = $it->key();     // If using the $key => $value syntax
    $value = $it->current();

    // Contents of loop in here

    $it->next();
}

As far as there being faster ways to iterate, it really depends on the problem. But I really need to ask, why? I understand wanting to make things more efficient, but I think you're wasting your time for a micro-optimization. Remember, Premature Optimization Is The Root Of All Evil...

Edit: Based upon the comment, I decided to do a quick benchmark run...

$a = array();
for ($i = 0; $i < 10000; $i++) {
    $a[] = $i;
}

$start = microtime(true);
foreach ($a as $k => $v) {
    $a[$k] = $v + 1;
}
echo "Completed in ", microtime(true) - $start, " Seconds\n";

$start = microtime(true);
foreach ($a as $k => &$v) {
    $v = $v + 1;
}
echo "Completed in ", microtime(true) - $start, " Seconds\n";

$start = microtime(true);
foreach ($a as $k => $v) {}
echo "Completed in ", microtime(true) - $start, " Seconds\n";

$start = microtime(true);
foreach ($a as $k => &$v) {}    
echo "Completed in ", microtime(true) - $start, " Seconds\n";

And the results:

Completed in 0.0073502063751221 Seconds
Completed in 0.0019769668579102 Seconds
Completed in 0.0011849403381348 Seconds
Completed in 0.00111985206604 Seconds

So if you're modifying the array in the loop, it's several times faster to use references...

And the overhead for just the reference is actually less than copying the array (this is on 5.3.2)... So it appears (on 5.3.2 at least) as if references are significantly faster...

Should be easier than that. Just use:

<Checkbox IsChecked="{Binding Path=myVar, UpdateSourceTrigger=PropertyChanged}" />

The solution that work for me is the following

_private.convertParams=function(params){
    var params= [];
    Object.keys(values).forEach(function(key) {
        params.push({"id":key,"option":"Igual","value":params[key].id})
    });
    return params;
}

This does not answer your specific question, but when I had the same problem I ended up here and I figured that more people might do the same.

The problem I had was that I had indeliberately declared my Get method as static. I missed this an entire forenoon, and it caused no warnings from attributes or similar.

Incorrect:

public class EchoController : ApiController
{
    public static string Get()
    {
        return string.Empty;
    }
}

Correct:

public class EchoController : ApiController
{
    public string Get()
    {
        return string.Empty;
    }
}

this line should work for your 3 examples:

sed -r 's#\?(page)=([^&]*)&#/\1/\2#g' a.txt

• I used -r to save some escaping .
• the line should be generic for your one, two three case. you don't have to do the sub 3 times

test with your example (a.txt):

kent$  echo "?page=one&
?page=two&
?page=three&"|sed -r 's#\?(page)=([^&]*)&#/\1/\2#g'
/page/one
/page/two
/page/three

Use the date function:

<?php
    echo date("m/d/y g:i (A)", $DB_Date_Field);
?>

In C++, there is no difference in main() and main(void).

But in C, main() will be called with any number of parameters.

Example:

main ( ){
    main(10,"abc",12.28);
    //Works fine !
    //It won't give the error. The code will compile successfully.
    //(May cause Segmentation fault when run)
}

main(void) will be called without any parameters. If we try to pass then this end up leading to a compiler error.

Example:

main (void) {
     main(10,"abc",12.13);
     //This throws "error: too many arguments to function ‘main’ "
}

Package

I used html-pdf

Easy to use and allows not only to save pdf as file, but also pipe pdf content to a WriteStream (so I could stream it directly to Google Storage to save there my reports).

Using css + images

It takes css into account. The only problem I faced - it ignored my images. The solution I found was to replace url in src attrribute value by base64, e.g.

<img src="data:image/png;base64,iVBOR...kSuQmCC">

You can do it with your code or to use one of online converters, e.g. https://www.base64-image.de/

Compile valid html code from html fragment + css

1. I had to get a fragment of my html document (I just appiled .html() method on jQuery selector).
2. Then I've read the content of the relevant css file.

Using this two values (stored in variables html and css accordingly) I've compiled a valid html code using Template string

var htmlContent = `
<!DOCTYPE html>
<html>
  <head>
    <style>
      ${css}
    </style>
  </head>
  <body id=direct-sellers-bill>
    ${html}
  </body>
</html>`

and passed it to create method of html-pdf.

Based on @ChadBefus 's answer and @shmosel comment, I'd recommend using this. (Efficient lookup, and works on pure java >= 8)

import java.util.stream.Collectors;
import java.util.function.Function;
import java.util.Map;
import java.util.Arrays;

public enum MyEnum {
    OPTION_1(-66),
    OPTION_2(32);

    private int value;
    private MyEnum(final int value) {
        this.value = value;
    }

    public int getValue() {
        return this.value;
    }

    private static Map<Integer, MyEnum> reverseLookup =
        Arrays.stream(MyEnum.values()).collect(Collectors.toMap(MyEnum::getValue, Function.identity()));

    public static MyEnum fromInt(final int id) {
        return reverseLookup.getOrDefault(id, OPTION_1);
    }
    public static void main(String[] args) {
        System.out.println(fromInt(-66).toString());
    }
}

Multi-word (and multi-line) cursors/selection in VS Code

Multi-word:

Windows / OS X:

• Ctrl+Shift+L / ?+Shift+L selects all instances of the current highlighted word
• Ctrl+D / ?+D selects the next instance... and the one after that... etc.

Multi-line:

For multi-line selection, Ctrl+Alt+Down / ?+Alt+Shift+Down will extend your selection or cursor position to the next line. Ctrl+Right / ?+Right will move to the end of each line, no matter how long. To escape the multi-line selection, hit Esc.

See the VS Code keybindings (OS sensitive)

Just add them in one line command 2>> error 1>> output

However, note that >> is for appending if the file already has data. Whereas, > will overwrite any existing data in the file.

So, command 2> error 1> output if you do not want to append.

Just for completion's sake, you can write 1> as just > since the default file descriptor is the output. so 1> and > is the same thing.

So, command 2> error 1> output becomes, command 2> error > output

This is working sample that I copied from my project.

Using alias for referencing the tables to get the columns from different tables after joining them.

Select tb1.*, tb2.col1, tb2.col2 from table1 tb1 JOIN table2 tb2 on tb1.Id = tb2.Id

There is no direct option available. You cant't do db.collection("CollectionName").count(). Below are the two ways by which you can find the count of number of documents within a collection.

1 :- Get all the documents in the collection and then get it's size.(Not the best Solution)

db.collection("CollectionName").get().subscribe(doc=>{
console.log(doc.size)
})

By using above code your document reads will be equal to the size of documents within a collection and that is the reason why one must avoid using above solution.

2:- Create a separate document with in your collection which will store the count of number of documents in the collection.(Best Solution)

db.collection("CollectionName").doc("counts")get().subscribe(doc=>{
console.log(doc.count)
})

Above we created a document with name counts to store all the count information.You can update the count document in the following way:-

• Create a firestore triggers on the document counts
• Increment the count property of counts document when a new document is created.
• Decrement the count property of counts document when a document is deleted.

w.r.t price (Document Read = 1) and fast data retrieval the above solution is good.

For MongoDB shell version 3.0.5 insert the following command in the shell:

db.adminCommand('listDatabases')

or alternatively:

db.getMongo().getDBNames()

Just add the second .absolute div before the other .second div:

<div class="absolute" style="top: 54px"></div>
<div class="absolute">
    <div id="relative"></div>
</div>

Because the two elements have an index 0.

The other day I'd been solving the similar issue and found convenient to convert hex color string to int array [alpha, r, g, b]:

 /**
 * Hex color string to int[] array converter
 *
 * @param hexARGB should be color hex string: #AARRGGBB or #RRGGBB
 * @return int[] array: [alpha, r, g, b]
 * @throws IllegalArgumentException
 */

public static int[] hexStringToARGB(String hexARGB) throws IllegalArgumentException {

    if (!hexARGB.startsWith("#") || !(hexARGB.length() == 7 || hexARGB.length() == 9)) {

        throw new IllegalArgumentException("Hex color string is incorrect!");
    }

    int[] intARGB = new int[4];

    if (hexARGB.length() == 9) {
        intARGB[0] = Integer.valueOf(hexARGB.substring(1, 3), 16); // alpha
        intARGB[1] = Integer.valueOf(hexARGB.substring(3, 5), 16); // red
        intARGB[2] = Integer.valueOf(hexARGB.substring(5, 7), 16); // green
        intARGB[3] = Integer.valueOf(hexARGB.substring(7), 16); // blue
    } else hexStringToARGB("#FF" + hexARGB.substring(1));

    return intARGB;
}

As you probably know, the maximum request length is configured in TWO places.

1. maxRequestLength - controlled at the ASP.NET app level
2. maxAllowedContentLength - under <system.webServer>, controlled at the IIS level

The first case is covered by other answers to this question.

To catch THE SECOND ONE you need to do this in global.asax:

protected void Application_EndRequest(object sender, EventArgs e)
{
    //check for the "file is too big" exception if thrown at the IIS level
    if (Response.StatusCode == 404 && Response.SubStatusCode == 13)
    {
        Response.Write("Too big a file"); //just an example
        Response.End();
    }
}

For future seekers who might have dropped simple details like me, in my case I just have forgotten to call my action function with parentheses.

actions.js:

export function addNewComponent() {
  return {
    type: ADD_NEW_COMPONENT,
  };
}

myComponent.js:

import React, { useEffect } from 'react';
import { addNewComponent } from '../../redux/actions';

  useEffect(() => {
    dispatch(refreshAllComponents); // <= Here was what I've missed.
  }, []);

I've forgotten to dispatch the action function with (). So doing this solved my issue.

  useEffect(() => {
    dispatch(refreshAllComponents());
  }, []);

Again this might have nothing to do with OP's problem, but I hope I helps people with the same problem as mine.

A static library(.a) is a library that can be linked directly into the final executable produced by the linker,it is contained in it and there is no need to have the library into the system where the executable will be deployed.

A shared library(.so) is a library that is linked but not embedded in the final executable, so will be loaded when the executable is launched and need to be present in the system where the executable is deployed.

A dynamic link library on windows(.dll) is like a shared library(.so) on linux but there are some differences between the two implementations that are related to the OS (Windows vs Linux) :

A DLL can define two kinds of functions: exported and internal. The exported functions are intended to be called by other modules, as well as from within the DLL where they are defined. Internal functions are typically intended to be called only from within the DLL where they are defined.

An SO library on Linux doesn't need special export statement to indicate exportable symbols, since all symbols are available to an interrogating process.

There is not such a proper way to download all the things all together from JSFiddle but there is a hack way to do just that. Simply add "embedded/" or "embedded/result/" at the end of your JSFiddle URL!, and then you can save the whole page as an HTML file + the external libraries (if you wants).

Me, I'd do ('%f' % x).rstrip('0').rstrip('.') -- guarantees fixed-point formatting rather than scientific notation, etc etc. Yeah, not as slick and elegant as %g, but, it works (and I don't know how to force %g to never use scientific notation;-).

tl;dr (this tl;dr is from @sp00m's answer below)

$emit dispatches an event upwards ... $broadcast dispatches an event downwards

Detailed explanation

$rootScope.$emit only lets other $rootScope listeners catch it. This is good when you don't want every $scope to get it. Mostly a high level communication. Think of it as adults talking to each other in a room so the kids can't hear them.

$rootScope.$broadcast is a method that lets pretty much everything hear it. This would be the equivalent of parents yelling that dinner is ready so everyone in the house hears it.

$scope.$emit is when you want that $scope and all its parents and $rootScope to hear the event. This is a child whining to their parents at home (but not at a grocery store where other kids can hear).

$scope.$broadcast is for the $scope itself and its children. This is a child whispering to its stuffed animals so their parents can't hear.

Try putting display: block in the <li> tags instead of the <ul>

Justin is dead on. The key point here is that HTML is just a language for describing a document. Once the browser reads it, it's gone. Open tags, close tags, and formatting are all taken care of by the parser and then go away. Any tool that shows you HTML is generating it based on the contents of the document, so it will always be valid.

I had to explain this to another web developer once, and it took a little while for him to accept it.

You can try it for yourself in any JavaScript console:

el = document.createElement('div');
el.innerHTML = "<p>Some text<P>More text";
el.innerHTML; // <p>Some text</p><p>More text</p>

The un-closed tags and uppercase tag names are gone, because that HTML was parsed and discarded after the second line.

The right way to modify the document from JavaScript is with document methods (createElement, appendChild, setAttribute, etc.) and you'll observe that there's no reference to tags or HTML syntax in any of those functions. If you're using document.write, innerHTML, or other HTML-speaking calls to modify your pages, the only way to validate it is to catch what you're putting into them and validate that HTML separately.

That said, the simplest way to get at the HTML representation of the document is this:

document.documentElement.innerHTML

Best guess is you are on windows and your line ending settings are set for windows. See this topic: How to change line-ending settings

or use:

tr '\r\n' ' '

Also, you can check the compatibility troubleshooting

• Right-click on Visual Studio > select Troubleshoot compatibility.
• Select Troubleshoot Program.
• Check The program requires additional permissions.
• Click on Test the program.
• Wait for a moment until the program launch. Click Next.
• Select Yes, save these settings for this program.
• Wait for resolving the issue.
• Make sure the final status is fixed. Click Close.

Check the detail steps, and other ways to always open VS as Admin at Visual Studio requires the application to have elevated permissions.

To create a new empty column and fill it with the same value (here 100) for every row (in Toad for Oracle):

ALTER TABLE my_table ADD new_column INT;
UPDATE my_table SET new_column = 100;

1. You can try netstat

    netstat -vanp tcp | grep 3000
   

2. For macOS El Capitan and newer (or if your netstat doesn't support -p), use lsof

    lsof -i tcp:3000 
   

3. For Centos 7 use:

    netstat -vanp --tcp | grep 3000
   

This is the easiest way:

php -f /home/your_username/public_html/script.php

And if you want to log the script output to a file, add this to the end of the command:

>> /home/your_username/logs/someFile.txt 2>&1

Another way...

1. Install the Text FX plugin if you don't have it already
2. Go to the TextFX menu option -> zap all non printable characters to #. It will replace all invalid chars with 3 # symbols
3. Go to Find/Replace and look for ###. Replace it with a space.

This is nice if you can't remember the regex or don't care to look it up. But the regex mentioned by others is a nice solution as well.

Had the same problem. I apparently wrote the Main wrong:

public static void main(String[] args){

I missed the [] and that was the whole problem.

Check and recheck the Main function!

If you want to make transformation your app setting from web config file to web.Release.config,you have to do the following steps. Let your web.config app setting file is this-

<appSettings>
     <add key ="K1" value="Debendra Dash"/>
  </appSettings>

Now here is the web.Release.config for the transformation.

<appSettings>
    <add key="K1" value="value dynamicly from Realease"
       xdt:Transform="SetAttributes"
          xdt:Locator="Match(key)"   
         />
  </appSettings>

This will transform the value of K1 to the new value in realese Mode.

a <div> is a logical division in your content, semantically this would be my first choice if I wanted to group the heading with the list:

<div class="mydiv">
    <h3>The heading</h3>
    <ul>
       <li>item</li>
       <li>item</li>
       <li>item</li>
    </ul>
</div>

then you can use the following css to style everything together as one unit

.mydiv{}
.mydiv h3{}
.mydiv ul{}
.mydiv ul li{}
etc...

I think the officially preferred way is now to use Less, and either dynamically override the bootstrap.css (using less.js), or recompile bootstrap.css (using Node or the Less compiler).

From the Bootstrap docs, here's how to override bootstrap.css styles dynamically:

Download the latest Less.js and include the path to it (and Bootstrap) in the <head>.

 <link rel="stylesheet/less" href="/path/to/bootstrap.less">
    <script src="/path/to/less.js"></script>

To recompile the .less files, just save them and reload your page. Less.js compiles them and stores them in local storage.

Or if you prefer to statically compile a new bootstrap.css with your custom styles (for production environments):

Install the LESS command line tool via Node and run the following command:

$ lessc ./less/bootstrap.less > bootstrap.css

In vue cli-3 You can define the variable in main.js like

window.basurl="http://localhost:8000/";

And you can also access this variable in any component by using the the window.basurl

Edit: After updating to appcompat-v7:22.1.1 and using AppCompatActivity instead of ActionBarActivity my styles.xml looks like:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
</style>

Note: This means I am using a Toolbar provided by the framework (NOT included in an XML file).

This worked for me:
styles.xml file:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionBar">false</item>
    <item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
</style>

Update: A quote from Gabriele Mariotti's blog.

With the new Toolbar you can apply a style and a theme. They are different! The style is local to the Toolbar view, for example the background color. The app:theme is instead global to all ui elements inflated in the Toolbar, for example the color of the title and icons.

More an extension to the question than an answer, but it may add some perspective to the great technical answers above. I'm an experienced programmer in a number of areas, but a total noob to programming for the web. Now trying to build a web-based application using Zend Framework.

Definitely will implement an application-specific basic username/password authentication interface, but recognize that for a growing number of users the thought of yet another username and password is a deterrent. While not exactly social networking, I know that a very large percentage of the application's potential users already have facebook or twitter accounts. The application doesn't really want or need to access information about the user's account from those sites, it just wants to offer the convenience of not requiring the user to set up new account credentials if they don't want to. From a functionality point of view, that would seem a poster child for OpenID. But it seems that neither facebook nor twitter are OpenID providers as such, though they do support OAuth authentication to access their user's data.

In all the articles I've read about the two and how they differ, it wan't until I saw Karl Anderson's observation above, that "OAuth can be used for authentication, which can be thought of as a no-op authorization" that I saw any explicit confirmation that OAuth was good enough for what I wanted to do.

In fact, when I went to post this "answer", not being a member at the time, I looked long and hard at the bottom of this page at the options for identifying myself. The option for using an OpenID login or obtaining one if I didn't have one, but nothing about twitter or facebook, seemed to suggest that OAuth wasn't adequate for the job. But then I opened another window and looked for the general signup process for stackoverflow - and lo and behold there's a slew of 3rd-party authentication options including facebook and twitter. In the end I decided to use my google id (which is an OpenID) for exactly the reason that I didn't want to grant stackoverflow access to my friends list and anything else facebook likes to share about its users - but at least it's a proof point that OAuth is adequate for the use I had in mind.

It would really be great if someone could either post info or pointers to info about supporting this kind of multiple 3rd-part authorization setup, and how you deal with users that revoke authorization or lose access to their 3rd party site. I also get the impression that my username here identifies a unique stackoverflow account that I could access with basic authentication if I wanted to set it up, and also access this same account through other 3rd-party authenticators (e.g. so that I would be considered logged in to stackoverflow if I was logged in to any of google, facebook, or twitter...). Since this site is doing it, somebody here probably has some pretty good insight on the subject. :-)

Sorry this was so long, and more a question than an answer - but Karl's remark made it seem like the most appropriate place to post amidst the volume of threads on OAuth and OpenID. If there's a better place for this that I didn't find, I apologize in advance, I did try.

Because you rebased feature on top of the new master, your local feature is not a fast-forward of origin/feature anymore. So, I think, it's perfectly fine in this case to override the fast-forward check by doing git push origin +feature. You can also specify this in your config

git config remote.origin.push +refs/heads/feature:refs/heads/feature

If other people work on top of origin/feature, they will be disturbed by this forced update. You can avoid that by merging in the new master into feature instead of rebasing. The result will indeed be a fast-forward.

Best practice is using @NaturalId annotation. It can be used as the business key for some cases it is too complicated, so some fields are using as the identifier in the real world. For example, I have user class with user id as primary key, and email is also unique field. So we can use email as our natural id

@Entity
@Table(name="user")
public class User {
  @Id
  @Column(name="id")
  private int id;

  @NaturalId
  @Column(name="email")
  private String email;

  @Column(name="name")
  private String name;
}

To get our record, just simply use 'session.byNaturalId()'

Session session = sessionFactory.getCurrentSession();
User user = session.byNaturalId(User.class)
                   .using("email","[email protected]")
                   .load()

Resumee of Richard Fearn's answer , to make each second line gray:

jTable.setDefaultRenderer(Object.class, new DefaultTableCellRenderer()
{
    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
    {
        final Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
        c.setBackground(row % 2 == 0 ? Color.LIGHT_GRAY : Color.WHITE);
        return c;
    }
});

If you're running a single node cluster for some reason, you might simply need to do avoid replicas, like this:

curl -XPUT -H 'Content-Type: application/json' 'localhost:9200/_settings' -d '
{
    "index" : {
        "number_of_replicas" : 0
    }
}'

Doing this you'll force to use es without replicas

To understand why it does not return the list:

sort() doesn't return any value while the sort() method just sorts the elements of a given list in a specific order - ascending or descending without returning any value.

So problem is with answer = newList.sort() where answer is none.

Instead you can just do return newList.sort().

The syntax of the sort() method is:

list.sort(key=..., reverse=...)

Alternatively, you can also use Python's in-built function sorted() for the same purpose.

sorted(list, key=..., reverse=...)

Note: The simplest difference between sort() and sorted() is: sort() doesn't return any value while, sorted() returns an iterable list.

So in your case answer = sorted(newList).

Like this, using .limit():

var q = models.Post.find({published: true}).sort('date', -1).limit(20);
q.execFind(function(err, posts) {
  // `posts` will be of length 20
});

A hex "character" (nibble) is different from a "character"

To be clear on the bits vs byte, vs characters.

• 1 byte is 8 bits (for our purposes)
• 8 bits provides 2**8 possible combinations: 256 combinations

When you look at a hex character,

• 16 combinations of [0-9] + [a-f]: the full range of 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f
• 16 is less than 256, so one one hex character does not store a byte.
• 16 is 2**4: that means one hex character can store 4 bits in a byte (half a byte).
• Therefore, two hex characters, can store 8 bits, 2**8 combinations.
• A byte represented as a hex character is [0-9a-f][0-9a-f] and that represents both halfs of a byte (we call a half-byte a nibble).

When you look at a regular single-byte character, (we're totally going to skip multi-byte and wide-characters here)

• It can store far more than 16 combinations.
• The capabilities of the character are determined by the encoding. For instance, the ISO 8859-1 that stores an entire byte, stores all this stuff
• All that stuff takes the entire 2**8 range.
• If a hex-character in an md5() could store all that, you'd see all the lowercase letters, all the uppercase letters, all the punctuation and things like ¡°ÀÐàð, whitespace like (newlines, and tabs), and control characters (which you can't even see and many of which aren't in use).

So they're clearly different and I hope that provides the best break down of the differences.

You may solve it by adding android:fillViewport="true" to your ScrollView.

<ScrollView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:background="@color/white"
      android:fillViewport="true"
      android:scrollbars="vertical">

<ListView
      android:id="@+id/statusList"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:animationCache="false"
      android:divider="@null"
      android:scrollingCache="false"
      android:smoothScrollbar="true" />

</ScrollView>

before use that property, there was only one child of my list view is visible. after using that all the rows or child of list are visible.

This is the best way (IMHO).

List<String> myArrayList = new ArrayList<String>();
//.....
String[] myArray = myArrayList.toArray(new String[myArrayList.size()]);

This code works also:

String[] myArray = myArrayList.toArray(new String[0]);

But it less effective: the string array is created twice: first time zero-length array is created, then the real-size array is created, filled and returned. So, if since you know the needed size (from list.size()) you should create array that is big enough to put all elements. In this case it is not re-allocated.

Try this:

if(Math.floor(id) == id && $.isNumeric(id)) 
  alert('yes its an int!');

$.isNumeric(id) checks whether it's numeric or not
Math.floor(id) == id will then determine if it's really in integer value and not a float. If it's a float parsing it to int will give a different result than the original value. If it's int both will be the same.

This is an old question, but is still regularly viewed/needed. I want to post to caution readers like me that whitespace as mentioned in the OP's question is not the same as Regex's definition, to include newlines, tabs, and space characters -- Git asks you to be explicit. See some options here: https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration

As stated, git diff -b or git diff --ignore-space-change will ignore spaces at line ends. If you desire that setting to be your default behavior, the following line adds that intent to your .gitconfig file, so it will always ignore the space at line ends:

git config --global core.whitespace trailing-space

In my case, I found this question because I was interested in ignoring "carriage return whitespace differences", so I needed this:

git diff --ignore-cr-at-eol or git config --global core.whitespace cr-at-eol from here.

You can also make it the default only for that repo by omitting the --global parameter, and checking in the settings file for that repo. For the CR problem I faced, it goes away after check-in if warncrlf or autocrlf = true in the [core] section of the .gitconfig file.

If you'd like something a bit more readable, you can do this:

A = np.squeeze(np.asarray(M))

Equivalently, you could also do: A = np.asarray(M).reshape(-1), but that's a bit less easy to read.

Here's an alternative solution using requests:

import requests
wjdata = requests.get('url').json()
print wjdata['data']['current_condition'][0]['temp_C']

A procedure does not have a return value, whereas a function has.

Example:

CREATE OR REPLACE PROCEDURE my_proc
   (p_name IN VARCHAR2 := 'John') as begin ... end

CREATE OR REPLACE FUNCTION my_func
   (p_name IN VARCHAR2 := 'John') return varchar2 as begin ... end

Notice how the function has a return clause between the parameter list and the "as" keyword. This means that it is expected to have the last statement inside the body of the function read something like:

return(my_varchar2_local_variable);

Where my_varchar2_local_variable is some varchar2 that should be returned by that function.

You should consider that a "true value" is everything except 0 and not only 1. So instead of 1=1 you should write 1<>0.

Because when you will use parameter (@param <> 0) you could have some conversion issue.

The most know is Access which translate True value on control as -1 instead of 1.

The comparison with an epsilon value is what most people do (even in game programming).

You should change your implementation a little though:

bool AreSame(double a, double b)
{
    return fabs(a - b) < EPSILON;
}

Edit: Christer has added a stack of great info on this topic on a recent blog post. Enjoy.

I had the exact same problem in a project. The issue is that even though the fetch size might be small enough, the JDBCTemplate reads all the result of your query and maps it out in a huge list which might blow your memory. I ended up extending NamedParameterJdbcTemplate to create a function which returns a Stream of Object. That Stream is based on the ResultSet normally returned by JDBC but will pull data from the ResultSet only as the Stream requires it. This will work if you don't keep a reference of all the Object this Stream spits. I did inspire myself a lot on the implementation of org.springframework.jdbc.core.JdbcTemplate#execute(org.springframework.jdbc.core.ConnectionCallback). The only real difference has to do with what to do with the ResultSet. I ended up writing this function to wrap up the ResultSet:

private <T> Stream<T> wrapIntoStream(ResultSet rs, RowMapper<T> mapper) {
    CustomSpliterator<T> spliterator = new CustomSpliterator<T>(rs, mapper, Long.MAX_VALUE, NON-NULL | IMMUTABLE | ORDERED);
    Stream<T> stream = StreamSupport.stream(spliterator, false);
    return stream;
}
private static class CustomSpliterator<T> extends Spliterators.AbstractSpliterator<T> {
    // won't put code for constructor or properties here
    // the idea is to pull for the ResultSet and set into the Stream
    @Override
    public boolean tryAdvance(Consumer<? super T> action) {
        try {
            // you can add some logic to close the stream/Resultset automatically
            if(rs.next()) {
                T mapped = mapper.mapRow(rs, rowNumber++);
                action.accept(mapped);
                return true;
            } else {
                return false;
            }
        } catch (SQLException) {
            // do something with this Exception
        }
    }
}

you can add some logic to make that Stream "auto closable", otherwise don't forget to close it when you are done.

Most layout managers work best with a component's preferredSize, and most GUI's are best off allowing the components they contain to set their own preferredSizes based on their content or properties. To use these layout managers to their best advantage, do call pack() on your top level containers such as your JFrames before making them visible as this will tell these managers to do their actions -- to layout their components.

Often when I've needed to play a more direct role in setting the size of one of my components, I'll override getPreferredSize and have it return a Dimension that is larger than the super.preferredSize (or if not then it returns the super's value).

For example, here's a small drag-a-rectangle app that I created for another question on this site:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class MoveRect extends JPanel {
   private static final int RECT_W = 90;
   private static final int RECT_H = 70;
   private static final int PREF_W = 600;
   private static final int PREF_H = 300;
   private static final Color DRAW_RECT_COLOR = Color.black;
   private static final Color DRAG_RECT_COLOR = new Color(180, 200, 255);
   private Rectangle rect = new Rectangle(25, 25, RECT_W, RECT_H);
   private boolean dragging = false;
   private int deltaX = 0;
   private int deltaY = 0;

   public MoveRect() {
      MyMouseAdapter myMouseAdapter = new MyMouseAdapter();
      addMouseListener(myMouseAdapter);
      addMouseMotionListener(myMouseAdapter);
   }

   @Override
   protected void paintComponent(Graphics g) {
      super.paintComponent(g);
      if (rect != null) {
         Color c = dragging ? DRAG_RECT_COLOR : DRAW_RECT_COLOR;
         g.setColor(c);
         Graphics2D g2 = (Graphics2D) g;
         g2.draw(rect);
      }
   }

   @Override
   public Dimension getPreferredSize() {
      return new Dimension(PREF_W, PREF_H);
   }

   private class MyMouseAdapter extends MouseAdapter {

      @Override
      public void mousePressed(MouseEvent e) {
         Point mousePoint = e.getPoint();
         if (rect.contains(mousePoint)) {
            dragging = true;
            deltaX = rect.x - mousePoint.x;
            deltaY = rect.y - mousePoint.y;
         }
      }

      @Override
      public void mouseReleased(MouseEvent e) {
         dragging = false;
         repaint();
      }

      @Override
      public void mouseDragged(MouseEvent e) {
         Point p2 = e.getPoint();
         if (dragging) {
            int x = p2.x + deltaX;
            int y = p2.y + deltaY;
            rect = new Rectangle(x, y, RECT_W, RECT_H);
            MoveRect.this.repaint();
         }
      }
   }

   private static void createAndShowGui() {
      MoveRect mainPanel = new MoveRect();

      JFrame frame = new JFrame("MoveRect");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.getContentPane().add(mainPanel);
      frame.pack();
      frame.setLocationByPlatform(true);
      frame.setVisible(true);
   }

   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            createAndShowGui();
         }
      });
   }
}

Note that my main class is a JPanel, and that I override JPanel's getPreferredSize:

public class MoveRect extends JPanel {
   //.... deleted constants

   private static final int PREF_W = 600;
   private static final int PREF_H = 300;

   //.... deleted fields and constants

   //... deleted methods and constructors

   @Override
   public Dimension getPreferredSize() {
      return new Dimension(PREF_W, PREF_H);
   }

Also note that when I display my GUI, I place it into a JFrame, call pack(); on the JFrame, set its position, and then call setVisible(true); on my JFrame:

   private static void createAndShowGui() {
      MoveRect mainPanel = new MoveRect();

      JFrame frame = new JFrame("MoveRect");
      frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
      frame.getContentPane().add(mainPanel);
      frame.pack();
      frame.setLocationByPlatform(true);
      frame.setVisible(true);
   }

   public static void main(String[] args) {
      SwingUtilities.invokeLater(new Runnable() {
         public void run() {
            createAndShowGui();
         }
      });
   }
}

ElektroStudios answer is a bit misleading.

"when you launch a bat file the working dir is the dir where it was launched" This is true if the user clicks on the batch file in the explorer.

However, if the script is called from another script using the CALL command, the current working directory does not change.

Thus, inside your script, it is better to use %~dp0subfolder\file1.txt

Please also note that %~dp0 will end with a backslash when the current script is not in the current working directory. Thus, if you need the directory name without a trailing backslash, you could use something like

call :GET_THIS_DIR
echo I am here: %THIS_DIR%
goto :EOF

:GET_THIS_DIR
pushd %~dp0
set THIS_DIR=%CD%
popd
goto :EOF

To everyone having problems with Newtonsoft.Json v4.5 version try using this in web.config or app.config:

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
       <dependentAssembly>
           <assemblyIdentity name="Newtonsoft.Json"
               publicKeyToken="30AD4FE6B2A6AEED" culture="neutral"/>
           <bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0"/>
       </dependentAssembly>
    </assemblyBinding>
</runtime>

IMPORTANT: Check that the configuration tag of your config file has no namespace attribute (as suggested in https://stackoverflow.com/a/12011221/150370). Otherwise, assemblyBinding tags will be ignored.

As I understand, you want the average value for each id at each pass. The solution is

SELECT id, pass, avg(value) FROM data_r1
GROUP BY id, pass;

You could close your Android Application by calling System.exit(0).

You can also use sequence unpacking with zip:

L = [(1,2),(2,3),(4,5),(3,4),(6,7),(6,7),(3,8)]

_, res = zip(*L)

print(res)

# (2, 3, 5, 4, 7, 7, 8)

This also creates a tuple _ from the discarded first elements. Extracting only the second is possible, but more verbose:

from itertools import islice

res = next(islice(zip(*L), 1, None))

instead of using this

Vue.component('tabs', {
    template: `
        <div class="tabs">
          <ul>
            <li class="is-active"><a>Pictures</a></li>
            <li><a>Music</a></li>
            <li><a>Videos</a></li>
            <li><a>Documents</a></li>
          </ul>
        </div>

        <div class="tabs-content">
          <slot></slot>
        </div>
    `,
});

you should use

Vue.component('tabs', {
    template: `
      <div>
        <div class="tabs">
          <ul>
            <li class="is-active"><a>Pictures</a></li>
            <li><a>Music</a></li>
            <li><a>Videos</a></li>
            <li><a>Documents</a></li>
          </ul>
        </div>

        <div class="tabs-content">
          <slot></slot>
        </div>
      </div>
    `,
});

Renderer has been deprecated in Angular 4.0.0-rc.1, read the update below

The angular2 way is to use listen or listenGlobal from Renderer

For example, if you want to add a click event to a Component, you have to use Renderer and ElementRef (this gives you as well the option to use ViewChild, or anything that retrieves the nativeElement)

constructor(elementRef: ElementRef, renderer: Renderer) {

    // Listen to click events in the component
    renderer.listen(elementRef.nativeElement, 'click', (event) => {
      // Do something with 'event'
    })
);

You can use listenGlobal that will give you access to document, body, etc.

renderer.listenGlobal('document', 'click', (event) => {
  // Do something with 'event'
});

Note that since beta.2 both listen and listenGlobal return a function to remove the listener (see breaking changes section from changelog for beta.2). This is to avoid memory leaks in big applications (see #6686).

So to remove the listener we added dynamically we must assign listen or listenGlobal to a variable that will hold the function returned, and then we execute it.

// listenFunc will hold the function returned by "renderer.listen"
listenFunc: Function;

// globalListenFunc will hold the function returned by "renderer.listenGlobal"
globalListenFunc: Function;

constructor(elementRef: ElementRef, renderer: Renderer) {
    
    // We cache the function "listen" returns
    this.listenFunc = renderer.listen(elementRef.nativeElement, 'click', (event) => {
        // Do something with 'event'
    });

    // We cache the function "listenGlobal" returns
    this.globalListenFunc = renderer.listenGlobal('document', 'click', (event) => {
        // Do something with 'event'
    });
}

ngOnDestroy() {
    // We execute both functions to remove the respectives listeners

    // Removes "listen" listener
    this.listenFunc();
    
    // Removs "listenGlobal" listener
    this.globalListenFunc();
}

Here's a plnkr with an example working. The example contains the usage of listen and listenGlobal.

Using RendererV2 with Angular 4.0.0-rc.1+ ^{_{(Renderer2 since 4.0.0-rc.3)}}

• 25/02/2017: Renderer has been deprecated, now we should use RendererV2 (see line below). See the commit.

• 10/03/2017: RendererV2 was renamed to Renderer2. See the breaking changes.

RendererV2 has no more listenGlobal function for global events (document, body, window). It only has a listen function which achieves both functionalities.

For reference, I'm copy & pasting the source code of the DOM Renderer implementation since it may change (yes, it's angular!).

listen(target: 'window'|'document'|'body'|any, event: string, callback: (event: any) => boolean):
      () => void {
    if (typeof target === 'string') {
      return <() => void>this.eventManager.addGlobalEventListener(
          target, event, decoratePreventDefault(callback));
    }
    return <() => void>this.eventManager.addEventListener(
               target, event, decoratePreventDefault(callback)) as() => void;
  }

As you can see, now it verifies if we're passing a string (document, body or window), in which case it will use an internal addGlobalEventListener function. In any other case, when we pass an element (nativeElement) it will use a simple addEventListener

To remove the listener it's the same as it was with Renderer in angular 2.x. listen returns a function, then call that function.

Example

// Add listeners
let global = this.renderer.listen('document', 'click', (evt) => {
  console.log('Clicking the document', evt);
})

let simple = this.renderer.listen(this.myButton.nativeElement, 'click', (evt) => {
  console.log('Clicking the button', evt);
});

// Remove listeners
global();
simple();

Finding of week number for each date of a month (considering Monday as beginning of the week)

Keep the first date of month contant $B$13

=WEEKNUM(B18,2)-WEEKNUM($B$13,2)+1

WEEKNUM(B18,2) - returns the week number of the date mentioned in cell B18

WEEKNUM($B$13,2) - returns the week number of the 1st date of month in cell B13

It can be done by jquery and css. i did it in a way that can be used in dynamic situations , you just have to change background-image in jquery and it will do every thing , also you can change the time in css.

The fiddle : https://jsfiddle.net/Naderial/zohfvqz7/

Html:

<div class="test">

CSS :

.test {
  /* as default, we set a background-image , but it is not nessesary */
  background-image: url(http://lorempixel.com/400/200);
  width: 200px;
  height: 200px;
  /* we set transition to 'all' properies - but you can use it just for background image either - by default the time is set to 1 second, you can change it yourself*/
  transition: linear all 1s;
  /* if you don't use delay , background will disapear and transition will start from a white background - you have to set the transition-delay the same as transition time OR more , so there won't be any problems */
  -webkit-transition-delay: 1s;/* Safari */
  transition-delay: 1s;
}

JS:

$('.test').click(function() {
  //you can use all properties : background-color  - background-image ...
  $(this).css({
    'background-image': 'url(http://lorempixel.com/400/200)'
  });
});

assuming certain column names...

INSERT one

newToner = Toner(toner_id = 1,
                    toner_color = 'blue',
                    toner_hex = '#0F85FF')

dbsession.add(newToner)   
dbsession.commit()

INSERT multiple

newToner1 = Toner(toner_id = 1,
                    toner_color = 'blue',
                    toner_hex = '#0F85FF')

newToner2 = Toner(toner_id = 2,
                    toner_color = 'red',
                    toner_hex = '#F01731')

dbsession.add_all([newToner1, newToner2])   
dbsession.commit()

UPDATE

q = dbsession.query(Toner)
q = q.filter(Toner.toner_id==1)
record = q.one()
record.toner_color = 'Azure Radiance'

dbsession.commit()

or using a fancy one-liner using MERGE

record = dbsession.merge(Toner( **kwargs))

All the answers above are great. Only one thing is missing, be sure to drag the grey buttons to see the table (step number 2):

You have to be specific about the columns you are selecting. If your user table had four columns id, name, username, opted_in you must select exactly those four columns from the query. The syntax looks like:

INSERT INTO user (id, name, username, opted_in)
  SELECT id, name, username, opted_in 
  FROM user LEFT JOIN user_permission AS userPerm ON user.id = userPerm.user_id

However, there does not appear to be any reason to join against user_permission here, since none of the columns from that table would be inserted into user. In fact, this INSERT seems bound to fail with primary key uniqueness violations.

MySQL does not support inserts into multiple tables at the same time. You either need to perform two INSERT statements in your code, using the last insert id from the first query, or create an AFTER INSERT trigger on the primary table.

INSERT INTO user (name, username, email, opted_in) VALUES ('a','b','c',0);
/* Gets the id of the new row and inserts into the other table */
INSERT INTO user_permission (user_id, permission_id) VALUES (LAST_INSERT_ID(), 4)

Or using a trigger:

CREATE TRIGGER creat_perms AFTER INSERT ON `user`
FOR EACH ROW
BEGIN
  INSERT INTO user_permission (user_id, permission_id) VALUES (NEW.id, 4)
END

If you're okay with using shorthands in your code (instead of writing explicit if blocks, like some coding standards recommend), you can further simplify Marius Schulz's answer with this one-liner:

in_array ($value, $array) || $array [] = $value;

Simply put, from the point of view of the user, a static method either uses no variables at all or all of the variables it uses are local to the method or they are static fields. Defining a method as static gives a slight performance benefit.

Use the string.substring(from, to) API. In your case, use string.substring(0,8).

For this example you will need to create your own type, that would be an array. Then you create a bigger array which elements are of type you have just created.

To run my example you will need to fill columns A and B in Sheet1 with some values. Then run test(). It will read first two rows and add the values to the BigArr. Then it will check how many rows of data you have and read them all, from the place it has stopped reading, i.e., 3rd row.

Make sure that you have compiled your *.cs file before browsing the ASPX page.

An alternative would be add the public half of the user's key to the authorized-keys file on the target system. On the system you are initiating the transfer from, you can run an ssh-agent daemon and add the private half of the key to the agent. The batch job can then be configured to use the agent to get the private key, rather than prompting for the key's password.

This should be do-able on either a UNIX/Linux system or on Windows platform using pageant and pscp.

How can I make xargs execute the command exactly once for each line of input given?

-L 1 is the simple solution but it does not work if any of the files contain spaces in them. This is a key function of find's -print0 argument – to separate the arguments by '\0' character instead of whitespace. Here's an example:

echo "file with space.txt" | xargs -L 1 ls
ls: file: No such file or directory
ls: with: No such file or directory
ls: space.txt: No such file or directory

A better solution is to use tr to convert newlines to null (\0) characters, and then use the xargs -0 argument. Here's an example:

echo "file with space.txt" | tr '\n' '\0' | xargs -0 ls
file with space.txt

If you then need to limit the number of calls you can use the -n 1 argument to make one call to the program for each input:

echo "file with space.txt" | tr '\n' '\0' | xargs -0 -n 1 ls

This also allows you to filter the output of find before converting the breaks into nulls.

find . -name \*.xml | grep -v /target/ | tr '\n' '\0' | xargs -0 tar -cf xml.tar

As much as I prefer this approach:-

    api.com/users?id=id1,id2,id3,id4,id5

The correct way is

    api.com/users?ids[]=id1&ids[]=id2&ids[]=id3&ids[]=id4&ids[]=id5

or

    api.com/users?ids=id1&ids=id2&ids=id3&ids=id4&ids=id5

This is how rack does it. This is how php does it. This is how node does it as well...

I have the same issue with postgres 11 on my mac. I get this error every time after restart

psql: could not connect to server: No such file or directory

Is the server running locally and accepting connections on 
Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

As a temporary fix I do

brew services stop postgresql@11
brew services start postgresql@11

In most browsers, you can use a javascript variable instead of using document.getElementById. Say your html body content is like this:

<section id="mySection"> Hello </section>

Then you can just refer to mySection as a variable in javascript:

mySection.innerText += ', world'
// same as: document.getElementById('mySection').innerText += ', world'

See this snippet:

mySection.innerText += ', world!'

<section id="mySection"> Hello </section>

SELECT o.*, GROUP_CONCAT(c.name) FROM Orders AS o , Company.c
    WHERE FIND_IN_SET(c.CompanyID , o.attachedCompanyIDs) GROUP BY o.attachedCompanyIDs

Put a global statement at the top of your function and you should be good:

def onLoadFinished(result):
    global feed
    ...

To demonstrate what I mean, look at this little test:

x = 0
def t():
    x += 1
t()

this blows up with your exact same error where as:

x = 0
def t():
    global x
    x += 1
t()

does not.

The reason for this is that, inside t, Python thinks that x is a local variable. Furthermore, unless you explicitly tell it that x is global, it will try to use a local variable named x in x += 1. But, since there is no x defined in the local scope of t, it throws an error.

I would prefer not use Count function at all:

IF [NOT] EXISTS ( SELECT 1 FROM MyTable WHERE ... )
     <do smth>

For example if you want to check if user exists before inserting it into the database the query can look like this:

IF NOT EXISTS ( SELECT 1 FROM Users WHERE FirstName = 'John' AND LastName = 'Smith' )
BEGIN
    INSERT INTO Users (FirstName, LastName) VALUES ('John', 'Smith')
END

I'm fully aware that the code in the original quesiton displays a situation of being navbar related. But as you also dive into other compontents, it maybe helpful to know that the class options for text styling may not work.

But you can still create your own helper classes to keep the "Bootstrap flow" going in your HTML. Here is one idea to help style links that are in panel-title regions.

The following code by itself will not style a warning color on your anchor link...

<div class="panel panel-default my-panel-styles"> 
...    
  <h4 class="panel-title">
    <a class="accordion-toggle btn-block text-warning" data-toggle="collapse" data-parent="#accordion" href="#collapseOne">
      My Panel title that is also a link
    </a>
  </h4>
 ...
 </div>

But you could extend the Bootstrap styling package by adding your own class with appropriate colors like this...

.my-panel-styles .text-muted {color:#777;}
.my-panel-styles .text-primary {color:#337ab7;}
.my-panel-styles .text-success {color:#d44950;}
.my-panel-styles .text-info {color:#31708f;}
.my-panel-styles .text-warning {color:#8a6d3b;}
.my-panel-styles .text-danger {color:#a94442;}

...Now you can continue building out your panel anchor links with the Bootstrap colors you want.

Not that I know of, unless you select from INFORMATION_SCHEMA, as others have mentioned.

However, the SHOW command is pretty flexible, E.g.:

SHOW tables like '%s%'

        FileInputStream fis = new FileInputStream(excel);
        XSSFWorkbook book = new XSSFWorkbook(fis);
        XSSFSheet sheet = book.getSheetAt(0);

        Iterator<Row> itr = sheet.iterator();

        // Iterating over Excel file in Java
        while (itr.hasNext()) {
            Row row = itr.next();

            Iterator<Cell> cellIterator = row.cellIterator();
            while (cellIterator.hasNext()) {

This depends on the database server, but it is often called something like CEIL or CEILING. For example, in MySQL...

mysql> select ceil(10.5);
+------------+
| ceil(10.5) |
+------------+
|         11 | 
+------------+

You can then do UPDATE PRODUCT SET price=CEIL(some_other_field);

You can't. Functions don't have names according to the standard (though mozilla has such an attribute) - they can only be assigned to variables with names.

Also your comment:

// access fully qualified name (ie "my.namespace.myFunc")

is inside the function my.namespace.myFunc.getFn

What you can do is return the constructor of an object created by new

So you could say

var obj = new my.namespace.myFunc();
console.info(obj.constructor); //my.namespace.myFunc

From site PostgreSQL, of date 02/04/2016 (https://jdbc.postgresql.org/download.html):

"This is the current version of the driver. Unless you have unusual requirements (running old applications or JVMs), this is the driver you should be using. It supports Postgresql 7.2 or newer and requires a 1.6 or newer JVM. It contains support for SSL and the javax.sql package. If you are using the 1.6 then you should use the JDBC4 version. If you are using 1.7 then you should use the JDBC41 version. If you are using 1.8 then you should use the JDBC42 versionIf you are using a java version older than 1.6 then you will need to use a JDBC3 version of the driver, which will by necessity not be current"

With your example:

<input type="checkbox" id="c2" name="c2" value="DE039230952"/>

Replace $$ with document.querySelectorAll in the examples:

$$('input') //Every input
$$('[id]') //Every element with id
$$('[id="c2"]') //Every element with id="c2"
$$('input,[id]') //Every input + every element with id
$$('input[id]') //Every input including id
$$('input[id="c2"]') //Every input including id="c2"
$$('input#c2') //Every input including id="c2" (same as above)
$$('input#c2[value="DE039230952"]') //Every input including id="c2" and value="DE039230952"
$$('input#c2[value^="DE039"]') //Every input including id="c2" and value has content starting with DE039
$$('input#c2[value$="0952"]') //Every input including id="c2" and value has content ending with 0952
$$('input#c2[value*="39230"]') //Every input including id="c2" and value has content including 39230

Use the examples directly with:

const $$ = document.querySelectorAll.bind(document);

Some additions:

$$(.) //The same as $([class])
$$(div > input) //div is parent tag to input
document.querySelector() //equals to $$()[0] or $()

For any wanderer that comes across this in the future. If your application and database are on different machines and you are getting the above error especially when using TransactionScope, enable Network DTC access. Steps to do this are:

1. Add firewall rules to allow your machines to talk to each other.
2. Ensure the distributed transaction coordinator service is running
3. Enable network dtc access. Run dcomcnfg. Go to Component sevices > My Computer > Distributed Transaction Coordinator > Local DTC. Right click properties.
4. Enable network dtc access as shown.

Important: Do not edit/change the user account and password in the DTC Logon account field, leave it as is, you will end up re-installing windows if you do.

take a look at this code

<form action="result.php" method="post">
Answer 1 <input type="radio" name="ans" value="ans1" /><br />
Answer 2 <input type="radio" name="ans" value="ans2"  /><br />
Answer 3 <input type="radio" name="ans" value="ans3"  /><br />
Answer 4 <input type="radio" name="ans" value="ans4"  /><br />
<input type="submit" value="submit" />
</form>

php

<?php 
if(isset($_POST['submit'])){
if(isset( $_POST['ans'])){  
echo "This is the value you are selected".$_POST['ans'];          
}         
}
?>

Assuming you're passing in strings rather than integers, try casting the arguments to integers:

def example(arg1, arg2, arg3):
     if int(arg1) == 1 and int(arg2) == 2 and int(arg3) == 3:
          print("Example Text")

(Edited to emphasize I'm not asking for clarification; I was trying to be diplomatic in my answer. )

In C, static means the function or variable you define can be only used in this file(i.e. the compile unit)

So, static inline means the inline function which can be used in this file only.

EDIT:

The compile unit should be The Translation Unit

Use this ..

    $str = rawurldecode($_SERVER['REQUEST_URI']);
    $arr = explode("{",$str);
    $arr1 = explode("}", $arr[1]);
    $jsS = '{'.$arr1[0].'}';
    $data = json_decode($jsS,true);

Now ..

use $data['elemname'] to access the values.

send jsonp request with JSON Object.

Request format :

$.ajax({
    method : 'POST',
    url : 'xxx.com',
    data : JSONDataObj, //Use JSON.stringfy before sending data
    dataType: 'jsonp',
    contentType: 'application/json; charset=utf-8',
    success : function(response){
      console.log(response);
    }
}) 

gmap.animateCamera(CameraUpdateFactory.newCameraPosition(new CameraPosition(new LatLng(9.491327, 76.571404), 10, 30, 0)));

Another way of doing it. This approach can be useful for changing the text to 2 different colors, just by adding 2 spans.

Label1.Text = "String with original color" + "<b><span style=""color:red;"">" + "Your String Here" + "</span></b>";

If you want unified way to handle both uncaught errors and unhandled promise rejections you may have a look on uncaught library.

EDIT

<script type="text/javascript" src=".../uncaught/lib/index.js"></script>

<script type="text/javascript">
    uncaught.start();
    uncaught.addListener(function (error) {
        console.log('Uncaught error or rejection: ', error.message);
    });
</script>

It listens window.unhandledrejection in addition to window.onerror.

If you are using the windows CMD you can use this command to create a database using sqlite3

C:\sqlite3.exe DBNAME.db ".read DBSCRIPT.sql"

If you haven't a database with that name sqlite3 will create one, and if you already have one, it will run it anyways but with the "TABLENAME already exists" error, I think you can also use this command to change an already existing database (but im not sure)

Here's a full sample of how to parse Json content. The example takes the Android versions statistics (found from Android Studio source code here, which links to here).

Copy the "distributions.json" file you get from there into res/raw, as a fallback.

build.gradle

    implementation 'com.google.code.gson:gson:2.8.6'

manifest

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

MainActivity.kt

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        if (savedInstanceState != null)
            return
        thread {
            // https://cs.android.com/android/platform/superproject/+/studio-master-dev:tools/adt/idea/android/src/com/android/tools/idea/stats/DistributionService.java
            var root: JsonArray
            Log.d("AppLog", "loading...")
            try {
                HttpURLConnection.setFollowRedirects(true)
                val statsUrl = "https://dl.google.com/android/studio/metadata/distributions.json" //just a string
                val url = URL(statsUrl)
                val request: HttpURLConnection = url.openConnection() as HttpURLConnection
                request.connectTimeout = 3000
                request.connect()
                InputStreamReader(request.content as InputStream).use {
                    root = JsonParser.parseReader(it).asJsonArray
                }
            } catch (e: Exception) {
                Log.d("AppLog", "error while loading from Internet, so using fallback")
                e.printStackTrace()
                InputStreamReader(resources.openRawResource(R.raw.distributions)).use {
                    root = JsonParser.parseReader(it).asJsonArray
                }
            }
            val decimalFormat = DecimalFormat("0.00")
            Log.d("AppLog", "result:")

            root.forEach {
                val androidVersionInfo = it.asJsonObject
                val versionNickName = androidVersionInfo.get("name").asString
                val versionName = androidVersionInfo.get("version").asString
                val versionApiLevel = androidVersionInfo.get("apiLevel").asInt
                val marketSharePercentage = androidVersionInfo.get("distributionPercentage").asFloat * 100f
                Log.d("AppLog", "\"$versionNickName\" - $versionName - API$versionApiLevel - ${decimalFormat.format(marketSharePercentage)}%")
            }
        }
    }
}

As alternative to the dependency, you can also use this instead:

InputStreamReader(request.content as InputStream).use {
    val jsonArray = JSONArray(it.readText())
}

and the fallback:

InputStreamReader(resources.openRawResource(R.raw.distributions)).use {
    val jsonArray = JSONArray(it.readText())
}

Go into Simulator-> Hardware->Keyboard and unchecking Connect Hardware Keyboard.

The same as many answers above BUT did not change for me until I quit and restart the simulator. xcode 8.2.1 and Simulator 10.0.

You can do it without setlocal, because of the setlocal command the variable won't survive an endlocal because it was created in setlocal. In this way the variable will be defined the right way.

To do that use this code:

set var1=A

set var2=B

set AB=hi

call set newvar=%%%var1%%var2%%%

echo %newvar% 

Note: You MUST use call before you set the variable or it won't work.

char **orderIds;

orderIds = malloc(variableNumberOfElements * sizeof(char*));

for(int i = 0; i < variableNumberOfElements; i++) {
  orderIds[i] = malloc((ID_LEN + 1) * sizeof(char));
  strcpy(orderIds[i], your_string[i]);
}

just an additional comment to the approved answer. You may get a crash when moving the cursor on edittext field due to parsing. I did a try catch statement, but implement your own code.

@Override public void onTextChanged(CharSequence s, int start, int before, int count) {
        if(!s.toString().equals(current)){
        amountEditText.removeTextChangedListener(this);

            String cleanString = s.toString().replaceAll("[$,.]", "");

            try{
                double parsed = Double.parseDouble(cleanString);
                String formatted = NumberFormat.getCurrencyInstance().format((parsed/100));
                current = formatted;
                amountEditText.setText(formatted);
                amountEditText.setSelection(formatted.length());
            } catch (Exception e) {

            }

            amountEditText.addTextChangedListener(this);
        }
    }

alternative solution

function scrollToBottom(element) {
  element.scroll({ top: element.scrollHeight, behavior: 'smooth' });
}

This is the problem

double a[] = null;

Since a is null, NullPointerException will arise every time you use it until you initialize it. So this:

a[i] = var;

will fail.

A possible solution would be initialize it when declaring it:

double a[] = new double[PUT_A_LENGTH_HERE]; //seems like this constant should be 7

IMO more important than solving this exception, is the fact that you should learn to read the stacktrace and understand what it says, so you could detect the problems and solve it.

java.lang.NullPointerException

This exception means there's a variable with null value being used. How to solve? Just make sure the variable is not null before being used.

at twoten.TwoTenB.(TwoTenB.java:29)

This line has two parts:

• First, shows the class and method where the error was thrown. In this case, it was at <init> method in class TwoTenB declared in package twoten. When you encounter an error message with SomeClassName.<init>, means the error was thrown while creating a new instance of the class e.g. executing the constructor (in this case that seems to be the problem).
• Secondly, shows the file and line number location where the error is thrown, which is between parenthesis. This way is easier to spot where the error arose. So you have to look into file TwoTenB.java, line number 29. This seems to be a[i] = var;.

From this line, other lines will be similar to tell you where the error arose. So when reading this:

at javapractice.JavaPractice.main(JavaPractice.java:32)

It means that you were trying to instantiate a TwoTenB object reference inside the main method of your class JavaPractice declared in javapractice package.

1. Type cmd in program start
2. Copy and Paste following on dos prompt

set PATH="%PATH%;C:\Program Files\Java\jdk1.6.0_18\bin"

By default link color is blue and the visited color is purple. Also, the text-decoration is underlined and the color is blue. If you want to keep the same color for visited, hover and focus then follow below code-

For example color is: #000

a:visited, a:hover, a:focus {
    text-decoration: none;
    color: #000;
}

If you want to use a different color for hover, visited and focus. For example Hover color: red visited color: green and focus color: yellow then follow below code

   a:hover {
        color: red;
    }
    a:visited {
        color: green;
    }
    a:focus {
        color: yellow;
    }

NB: good practice is to use color code.

Another way (assuming you are using vue-router), is to map the query param to a prop in your router. Then you can treat it like any other prop in your component code. For example, add this route;

{ 
    path: '/mypage', 
    name: 'mypage', 
    component: MyPage, 
    props: (route) => ({ foo: route.query.foo })  
}

Then in your component you can add the prop as normal;

props: {
    foo: {
        type: String,
        default: null
    }
},

Then it will be available as this.foo and you can do anything you want with it (like set a watcher, etc.)

The typical pattern in this situation is to pass the elements in a comma delimited list, and then in SQL split that out into a table you can use. Most people usually create a specified function for doing this like:

 INSERT INTO <SomeTempTable>
 SELECT item FROM dbo.SplitCommaString(@myParameter)

And then you can use it in other queries.

This is how I achieved the same in Scala. I am not sure if it is more efficient than the valid answer, but it requires less coding

val parquetFileDF = sqlContext.read.parquet("myParquetFule.parquet")

val myRow7th = parquetFileDF.rdd.take(7).last

Read the Request.Form NameValueCollection and process your logic accordingly:

NameValueCollection nvc = Request.Form;
string userName, password;
if (!string.IsNullOrEmpty(nvc["txtUserName"]))
{
  userName = nvc["txtUserName"];
}

if (!string.IsNullOrEmpty(nvc["txtPassword"]))
{
  password = nvc["txtPassword"];
}

//Process login
CheckLogin(userName, password);

... where "txtUserName" and "txtPassword" are the Names of the controls on the posting page.

git log --oneline --decorate --all --graph

A visual tree with branch names included.

Use this to add it as an alias

git config --global alias.tree "log --oneline --decorate --all --graph"

You call it with

git tree

Many ways to do this. You could use wildcards in double brackets:

str="/some/directory/file"
if [[ $str == /* ]]; then echo 1; else echo 0; fi

You can use substring expansion:

if [[ ${str:0:1} == "/" ]] ; then echo 1; else echo 0; fi

Or a regex:

if [[ $str =~ ^/ ]]; then echo 1; else echo 0; fi

netstat -ln | awk '/^(tcp|udp)/ { split($4, a, /:/); print $1, a[2]}' | sort -u

gives you the active tcp/udp ports. Then you can use the ports with fuser -n tcp or fuser -n udp, as root, and supposing that fuser is GNU fuser or has similar options.

If you need more help, let me know.

OpenCV has region of interest functions which you may find useful. If you are using the cv::Mat then you could use something like the following.

// You mention that you start with a CVMat* imagesource
CVMat * imagesource;

// Transform it into the C++ cv::Mat format
cv::Mat image(imagesource); 

// Setup a rectangle to define your region of interest
cv::Rect myROI(10, 10, 100, 100);

// Crop the full image to that image contained by the rectangle myROI
// Note that this doesn't copy the data
cv::Mat croppedImage = image(myROI);

To build a debug APK, open a command line and navigate to the root of your project directory. To initiate a debug build, invoke the assembleDebug task:

gradlew assembleDebug

This creates an APK named module_name-debug.apk in project_name/module_name/build/outputs/apk/.

1. Right Click on "My Computer" and click properties
2. Click Advanced System Settings
3. Click Environment Variables
4. In second box under "System Variables" scroll down and click on variable "Path" and click EDIT
5. Make sure the path is included in the Variable Value by appending (a semicolon if it's not there and) C:\Program Files (x86)\Git\bin; ( or whatever is the path to your ssh.exe )
6. OK > OK > OK and RESTART WINDOWS
7. You'll have to run vagrant up but after that vagrant ssh should work permanently

How about exporting the variable, but only inside the subshell?:

(export FOO=bar && somecommand someargs | somecommand2)

Keith has a point, to unconditionally execute the commands, do this:

(export FOO=bar; somecommand someargs | somecommand2)

Here is Java code for three approaches:
1. Using Map O(n), HashSet can also be used here.
2. Sort array and then use BinarySearch to look for complement O(nLog(n))
3. Traditional BruteForce two loops O(n^2)

public class PairsEqualToSum {

public static void main(String[] args) {
    int a[] = {1,10,5,8,2,12,6,4};
    findPairs1(a,10);
    findPairs2(a,10);
    findPairs3(a,10);

}


//Method1 - O(N) use a Map to insert values as keys & check for number's complement in map
    static void findPairs1(int[]a, int sum){
        Map<Integer, Integer> pairs = new HashMap<Integer, Integer>();
        for(int i=0; i<a.length; i++){
            if(pairs.containsKey(sum-a[i]))
                System.out.println("("+a[i]+","+(sum-a[i])+")");
            else
               pairs.put(a[i], 0);
        }
    }



//Method2 - O(nlog(n)) using Sort
static void findPairs2(int[]a, int sum){
        Arrays.sort(a);
        for(int i=0; i<a.length/2; i++){
            int complement = sum - a[i];
            int foundAtIndex = Arrays.binarySearch(a,complement);
            if(foundAtIndex >0 && foundAtIndex != i) //to avoid situation where binarySearch would find the original and not the complement like "5"
                System.out.println("("+a[i]+","+(sum-a[i])+")");
        }
 }

//Method 3 - Brute Force O(n^2)
static void findPairs3(int[]a, int sum){

    for(int i=0; i<a.length; i++){
        for(int j=i; j<a.length;j++){
            if(a[i]+a[j] == sum)
                System.out.println("("+a[i]+","+a[j]+")");
        }
    }
}

}

Once you have selected the highest value, which is "12" in my example, you can then declare it as integer and increment your value:

$FileList = "1", "2", "11"
$foldername = [int]$FileList[2] + 1
$foldername

The ffmpeg wiki links back to this page in reference to "How to split video efficiently". I'm not convinced this page answers that question, so I did as @AlcubierreDrive suggested…

echo "Two commands" 
time ffmpeg -v quiet -y -i input.ts -vcodec copy -acodec copy -ss 00:00:00 -t 00:30:00 -sn test1.mkv
time ffmpeg -v quiet -y -i input.ts -vcodec copy -acodec copy -ss 00:30:00 -t 01:00:00 -sn test2.mkv
echo "One command" 
time ffmpeg -v quiet -y -i input.ts -vcodec copy -acodec copy -ss 00:00:00 -t 00:30:00 \
  -sn test3.mkv -vcodec copy -acodec copy -ss 00:30:00 -t 01:00:00 -sn test4.mkv

Which outputs...

One command  HD 3m30.79 #1 wins  

SD file = 1.35GB DVB transport stream
HD file = 3.14GB DVB transport stream

Conclusion

The single command is better if you are handling HD, it agrees with the manuals comments on using -ss after the input file to do a 'slow seek'. SD files have a negligible difference.

The two command version should be quicker by adding another -ss before the input file for the a 'fast seek' followed by the more accurate slow seek.

I think you may have missed this part in the tutorial:

Instead of referencing System.Data and System.Data.SqlClient you need to grab from Nuget:

System.Data.Common and System.Data.SqlClient.

Currently this creates dependency in project.json –> aspnetcore50 section to these two libraries.

"aspnetcore50": {
       "dependencies": {
           "System.Runtime": "4.0.20-beta-22523",
           "System.Data.Common": "4.0.0.0-beta-22605",
           "System.Data.SqlClient": "4.0.0.0-beta-22605"
       }
}

Try getting System.Data.Common and System.Data.SqlClient via Nuget and see if this adds the above dependencies for you, but in a nutshell you are missing System.Runtime.

Edit: As per Mozarts answer, if you are using .NET Core 3+, reference Microsoft.Data.SqlClient instead.

You can add this declaration to silence the warnings.

declare var obj: any;

I'm not sure what was your original reason for running Travis locally, if you just wanted to play with it, then stop reading here as it's irrelevant for you.

If you already have experience with hosted Travis and you want to get the same experience in your own datacenter, read on.

Since Dec 2014 Travis CI offers an Enterprise on-premises version.

http://blog.travis-ci.com/2014-12-19-introducing-travis-ci-enterprise/

The pricing is part of the article as well:

The licensing is done per seats, where every license includes 20 users. Pricing starts at $6,000 per license, which includes 20 users and 5 concurrent builds. There's a premium option with unlimited builds for $8,500.

This HTML is fine:

<a href="#" id="contactUs">Contact Us</a>                   
<div id="dialog" title="Contact form">
  <p>appear now</p>
</div>

You need to initialize the Dialog (not sure if you are doing this):

$(function() {
  // this initializes the dialog (and uses some common options that I do)
  $("#dialog").dialog({
    autoOpen : false, modal : true, show : "blind", hide : "blind"
  });

  // next add the onclick handler
  $("#contactUs").click(function() {
    $("#dialog").dialog("open");
    return false;
  });
});

I might deal with this in the duck-typing style, like others mention. How do I know a string is really a string? well, obviously by converting it to a string!

def myfunc(word):
    word = unicode(word)
    ...

If the arg is already a string or unicode type, real_word will hold its value unmodified. If the object passed implements a __unicode__ method, that is used to get its unicode representation. If the object passed cannot be used as a string, the unicode builtin raises an exception.

this will give you result that has the minimum price on all records.

SELECT *
FROM pieces
WHERE price =  ( SELECT MIN(price) FROM pieces )

When this happens, look in the Errors window and the Output window to see if there are any error messages. If that doesn't help, try running svcutil.exe manually, and see if there are any error messages.

I know this question has a good answer with 't', but thought I would add another solution.

$first = date("Y-m-d", strtotime("first day of this month"));
$last = date("Y-m-d", strtotime("last day of this month"));

It is a little hard to follow what you are really trying to do. Your first statement looks like you may be fetching the same exact QuerySet of Answer objects twice. First via answer_set.answers.all() and then again via .filter(id__in=...). Double check in the shell and see if this will give you the list of answers you are looking for:

answers = answer_set.answers.all()

Once you have that cleaned up so it is a little easier for you (and others working on the code) to read you might want to look into .exclude() and the __in field lookup.

existing_question_answers = QuestionAnswer.objects.filter(...)

new_answers = answers.exclude(question_answer__in=existing_question_answers)

The above lookup might not sync up with your model definitions but it will probably get you close enough to finish the job yourself.

If you still need to get a list of id values then you want to play with .values_list(). In your case you will probably want to add the optional flat=True.

answers.values_list('id', flat=True)

This question is the first result for Googling "svg rounded corners path". Phrogz suggestion to use stroke has some limitations (namely, that I cannot use stroke for other purposes, and that the dimensions have to be corrected for the stroke width).

Jlange suggestion to use a curve is better, but not very concrete. I ended up using quadratic Bézier curves for drawing rounded corners. Consider this picture of a corner marked with a blue dot and two red points on adjacent edges:

The two lines could be made with the L command. To turn this sharp corner into a rounded corner, start drawing a curve from the left red point (use M x,y to move to that point). Now a quadratic Bézier curve has just a single control point which you must set on the blue point. Set the end of the curve at the right red point. As the tangent at the two red points are in the direction of the previous lines, you will see a fluent transition, "rounded corners".

Now to continue the shape after the rounded corner, a straight line in a Bézier curve can be achieved by setting the control point between on the line between the two corners.

To help me with determining the path, I wrote this Python script that accepts edges and a radius. Vector math makes this actually very easy. The resulting image from the output:

#!/usr/bin/env python
# Given some vectors and a border-radius, output a SVG path with rounded
# corners.

They are a number of things to worry about when connecting to SQL Server on another machine.

• Host/IP address of the machine
• Initial catalog (database name)
• Valid username/password

Very often SQL Server may be running as a default instance which means you can simply specify the hostname/IP address, but you may encounter a scenario where it is running as a named instance (SQL Server Express Edition for instance). In this scenario you'll have to specify the hostname/instance name.

For those who are using Gradle, as @Billda mentioned, you can get the package name via:

BuildConfig.APPLICATION_ID

This gives you the package name declared in your app gradle:

android {
    defaultConfig {
        applicationId "com.domain.www"
    }
}

If you are interested to get the package name used by your java classes (which sometimes is different than applicationId), you can use

BuildConfig.class.getPackage().toString()

If you are confused which one to use, read here:

Note: The application ID used to be directly tied to your code's package name; so some Android APIs use the term "package name" in their method names and parameter names, but this is actually your application ID. For example, the Context.getPackageName() method returns your application ID. There's no need to ever share your code's true package name outside your app code.

there are many different situations memory will leak. One i encountered, which expose a map that should not be exposed and used in other place.

}

//in all this is a dangerous api, and should not expose 
public Map<String, Service> getAllServices() {
    return services;
