The latest dwr (http://directwebremoting.org/dwr/index.html) has ajax file uploads, complete with examples and nice stuff for users (like progress indicators and such).

It looks pretty nifty and dwr is fairly easy to use in general so this will be pretty good as well.

Android Studio 1.0.1 doesn't make it any clearer, but it does make it somehow easier. Here's what worked for me:

1) Using explorer, create an 'external_libs' folder (any other name is fine) inside the Project/app/src folder, where 'Project' is the name of your project

2) Copy your jar file into this 'external_libs' folder

3) In Android Studio, go to File -> Project Structure -> Dependencies -> Add -> File Dependency and navigate to your jar file, which should be under 'src/external_libs'

3) Select your jar file and click 'Ok'

Now, check your build.gradle (Module.app) script, where you'll see the jar already added under 'dependencies'

Easiest way for me to fix this issue:

1. close IDE.
2. delete "gradle" folder
3. re-open project.

You can use the createRef to change the state of the child component from the parent component. Here are all the steps.

1. Create a method to change the state in the child component.

   2 - Create a reference for the child component in parent component using React.createRef().

   3 - Attach reference with the child component using ref={}.

   4 - Call the child component method using this.yor-reference.current.method.

Parent component

class ParentComponent extends Component {
constructor()
{
this.changeChild=React.createRef()
}
  render() {
    return (
      <div>
        <button onClick={this.changeChild.current.toggleMenu()}>
          Toggle Menu from Parent
        </button>
        <ChildComponent ref={this.changeChild} />
      </div>
    );
  }
}

Child Component

class ChildComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      open: false;
    }
  }

  toggleMenu=() => {
    this.setState({
      open: !this.state.open
    });
  }

  render() {
    return (
      <Drawer open={this.state.open}/>
    );
  }
}

$statement = $this->sql->getSqlStringForSqlObject( HERE GOES Zend\Db\Sql\SelectSQL object );

echo "SQL statement: $statement";

Example:

$select = $this->sql->select();
...
$select->from(array( 'u' => 'users' ));
$select->join(...
$select->group('u.id');
...
$statement = $this->sql->getSqlStringForSqlObject($select);
echo $statement;

In terms of source control, you're "downstream" when you copy (clone, checkout, etc) from a repository. Information flowed "downstream" to you.

When you make changes, you usually want to send them back "upstream" so they make it into that repository so that everyone pulling from the same source is working with all the same changes. This is mostly a social issue of how everyone can coordinate their work rather than a technical requirement of source control. You want to get your changes into the main project so you're not tracking divergent lines of development.

Sometimes you'll read about package or release managers (the people, not the tool) talking about submitting changes to "upstream". That usually means they had to adjust the original sources so they could create a package for their system. They don't want to keep making those changes, so if they send them "upstream" to the original source, they shouldn't have to deal with the same issue in the next release.

Inspired in this answer I came up with a bit more object-oriented solution.

This is only valid if you're intending to read characters

You can override BufferedReader and implement something like this:

public class SafeBufferedReader extends BufferedReader{

    private long millisTimeout;

    ( . . . )

    @Override
    public int read(char[] cbuf, int off, int len) throws IOException {
        try {
            waitReady();
        } catch(IllegalThreadStateException e) {
            return 0;
        }
        return super.read(cbuf, off, len);
    }

    protected void waitReady() throws IllegalThreadStateException, IOException {
        if(ready()) return;
        long timeout = System.currentTimeMillis() + millisTimeout;
        while(System.currentTimeMillis() < timeout) {
            if(ready()) return;
            try {
                Thread.sleep(100);
            } catch (InterruptedException e) {
                break; // Should restore flag
            }
        }
        if(ready()) return; // Just in case.
        throw new IllegalThreadStateException("Read timed out");
    }
}

Here's an almost complete example.

I'm returning 0 on some methods, you should change it to -2 to meet your needs, but I think that 0 is more suitable with BufferedReader contract. Nothing wrong happened, it just read 0 chars. readLine method is a horrible performance killer. You should create a entirely new BufferedReader if you actually want to use readLine. Right now, it is not thread safe. If someone invokes an operation while readLines is waiting for a line, it will produce unexpected results

I don't like returning -2 where I am. I'd throw an exception because some people may just be checking if int < 0 to consider EOS. Anyway, those methods claim that "can't block", you should check if that statement is actually true and just don't override'em.

If you don't need ticks and such (e.g. for plotting qualitative illustrations) you could also use this quick workaround:

Make the axis invisible (e.g. with plt.gca().axison = False) and then draw them manually with plt.arrow.

All you have to do is read the code on getbootstrap.com:

Use character classes: [ \t]

I found out this very simple method while experimenting: set the scrollTo to the height of the div.

var myDiv = document.getElementById("myDiv");
window.scrollTo(0, myDiv.innerHeight);

If you are using .NET 3.5+ you could use LINQ (Language INtegrated Query).

test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();

There is actually a (subtle) difference between the two. Imagine you have the following code in File1.cs:

// File1.cs
using System;
namespace Outer.Inner
{
    class Foo
    {
        static void Bar()
        {
            double d = Math.PI;
        }
    }
}

Now imagine that someone adds another file (File2.cs) to the project that looks like this:

// File2.cs
namespace Outer
{
    class Math
    {
    }
}

The compiler searches Outer before looking at those using directives outside the namespace, so it finds Outer.Math instead of System.Math. Unfortunately (or perhaps fortunately?), Outer.Math has no PI member, so File1 is now broken.

This changes if you put the using inside your namespace declaration, as follows:

// File1b.cs
namespace Outer.Inner
{
    using System;
    class Foo
    {
        static void Bar()
        {
            double d = Math.PI;
        }
    }
}

Now the compiler searches System before searching Outer, finds System.Math, and all is well.

Some would argue that Math might be a bad name for a user-defined class, since there's already one in System; the point here is just that there is a difference, and it affects the maintainability of your code.

It's also interesting to note what happens if Foo is in namespace Outer, rather than Outer.Inner. In that case, adding Outer.Math in File2 breaks File1 regardless of where the using goes. This implies that the compiler searches the innermost enclosing namespace before it looks at any using directive.

In my case this (a with caret) occurred in code I generated from visual studio using my own tool for generating code. It was easy to solve:

Select single spaces ( ) in the document. You should be able to see lots of single spaces that are looking different from the other single spaces, they are not selected. Select these other single spaces - they are the ones responsible for the unwanted characters in the browser. Go to Find and Replace with single space ( ). Done.

PS: It's easier to see all similar characters when you place the cursor on one or if you select it in VS2017+; I hope other IDEs may have similar features

Maybe someone likes this way of writing if-then-else better than using guards

depends on Less 1.7.0

https://github.com/pixelass/more-or-less/blob/master/less/fn/_if.less

Usage:

.if(isnumber(2), {
    .-then(){
        log {
            isnumber: true;
        }
    }
    .-else(){
        log {
            isnumber: false;
        }
    }
});

.if(lightness(#fff) gt (20% * 2), {
    .-then(){
        log {
            is-light: true;
        }
    }
});

using on example from above

.if(@debug, {
    .-then(){
        header {
            background-color: yellow;
            #title {

Can you try this, you can use content: counter(page);

     @page {
       @bottom-left {
            content: counter(page) "/" counter(pages);

     }

Assuming the image data is already in the format you want, you don't need image ImageIO at all - you just need to write the data to the file:

// Note preferred way of declaring an array variable
byte[] data = Base64.decodeBase64(crntImage);
try (OutputStream stream = new FileOutputStream("c:/decode/abc.bmp")) {
    stream.write(data);
}

(I'm assuming you're using Java 7 here - if not, you'll need to write a manual try/finally statement to close the stream.)

If the image data isn't in the format you want, you'll need to give more details.

As @Quartz mentioned, you can do something like

stage('Tests') {
    parallel(
        'Unit Tests': {
            container('node') {
                sh("npm test --cat=unit")
            }
        },
        'API Tests': {
            container('node') {
                sh("npm test --cat=acceptance")
            }
        }
    )
}

For XCode 9.3 indexing issue - Uninstall the XCode and instal again from zero. Works for me.

Try this:

function someFunction(username, password) {
      return new Promise((resolve, reject) => {
        // Do something with the params username and password...
        if ( /* everything turned out fine */ ) {
          resolve("Stuff worked!");
        } else {
          reject(Error("It didn't work!"));
        }
      });
    }
    
    someFunction(username, password)
      .then((result) => {
        // Do something...
      })
      .catch((err) => {
        // Handle the error...
      });

In SQL Management Studio, right-click on a database and select "Properties" from the context menu. Look at the "Size" figure.

Use Application.GetSaveAsFilename() in the same way that you used Application.GetOpenFilename()

Use the code below

DateTime.Now.ToString("h:mm:ss tt")

You can't write to the HKCR (or HKLM) hives in Vista and newer versions of Windows unless you have administrative privileges. Therefore, you'll either need to be logged in as an Administrator before you run your utility, give it a manifest that says it requires Administrator level (which will prompt the user for Admin login info), or quit changing things in places that non-Administrators shouldn't be playing. :-)

Instead of mocking concrete class you should mock that class interface. Extract interface from XmlCupboardAccess class

public interface IXmlCupboardAccess
{
    bool IsDataEntityInXmlCupboard(string dataId, out string nameInCupboard, out string refTypeInCupboard, string nameTemplate = null);
}

And instead of

private Mock<XmlCupboardAccess> _xmlCupboardAccess = new Mock<XmlCupboardAccess>();

change to

private Mock<IXmlCupboardAccess> _xmlCupboardAccess = new Mock<IXmlCupboardAccess>();

Shift + Alt + r (Right click file -> Refactor -> Rename) when cursor is on class name. The file and constructors will be also changed.

Update version

Objective-C

Create:

NSDictionary *dictionary = @{@"myKey1": @7, @"myKey2": @5}; 

Change:

NSMutableDictionary *mutableDictionary = [dictionary mutableCopy];     //Make the dictionary mutable to change/add
mutableDictionary[@"myKey3"] = @3;

The short-hand syntax is called Objective-C Literals.

Swift

Create:

var dictionary = ["myKey1": 7, "myKey2": 5]

Change:

dictionary["myKey3"] = 3

Another somewhat obscure use of __slots__ is to add attributes to an object proxy from the ProxyTypes package, formerly part of the PEAK project. Its ObjectWrapper allows you to proxy another object, but intercept all interactions with the proxied object. It is not very commonly used (and no Python 3 support), but we have used it to implement a thread-safe blocking wrapper around an async implementation based on tornado that bounces all access to the proxied object through the ioloop, using thread-safe concurrent.Future objects to synchronise and return results.

By default any attribute access to the proxy object will give you the result from the proxied object. If you need to add an attribute on the proxy object, __slots__ can be used.

from peak.util.proxies import ObjectWrapper

class Original(object):
    def __init__(self):
        self.name = 'The Original'

class ProxyOriginal(ObjectWrapper):

    __slots__ = ['proxy_name']

    def __init__(self, subject, proxy_name):
        # proxy_info attributed added directly to the
        # Original instance, not the ProxyOriginal instance
        self.proxy_info = 'You are proxied by {}'.format(proxy_name)

        # proxy_name added to ProxyOriginal instance, since it is
        # defined in __slots__
        self.proxy_name = proxy_name

        super(ProxyOriginal, self).__init__(subject)

if __name__ == "__main__":
    original = Original()
    proxy = ProxyOriginal(original, 'Proxy Overlord')

    # Both statements print "The Original"
    print "original.name: ", original.name
    print "proxy.name: ", proxy.name

    # Both statements below print 
    # "You are proxied by Proxy Overlord", since the ProxyOriginal
    # __init__ sets it to the original object 
    print "original.proxy_info: ", original.proxy_info
    print "proxy.proxy_info: ", proxy.proxy_info

    # prints "Proxy Overlord"
    print "proxy.proxy_name: ", proxy.proxy_name
    # Raises AttributeError since proxy_name is only set on 
    # the proxy object
    print "original.proxy_name: ", proxy.proxy_name

My Expected code :

$('#my-select').val('').change();

working perfectly thank to @PanPipes for the usefull one.

Just to provide some insight:

require 'fruity'
require 'set'

array = [1,2,2,1,4,4,5,6,7,8,5,6] * 1_000

def mithun_sasidharan(ary)
  ary.uniq
end

def jaredsmith(ary)
  ary & ary
end

def lri(ary)
  counts = Hash.new(0)
  ary.each { |v| counts[v] += 1 }
  counts.select { |v, count| count == 1 }.keys 
end

def finks(ary)
  ary.to_set
end

def santosh_mohanty(ary)
    result = ary.reject.with_index do |ele,index|
      res = (ary[index+1] ^ ele)
      res == 0
    end
end

SHORT_ARRAY = [1,1,2,2,3,1]
mithun_sasidharan(SHORT_ARRAY) # => [1, 2, 3]
jaredsmith(SHORT_ARRAY) # => [1, 2, 3]
lri(SHORT_ARRAY) # => [3]
finks(SHORT_ARRAY) # => #<Set: {1, 2, 3}>
santosh_mohanty(SHORT_ARRAY) # => [1, 2, 3, 1]

puts 'Ruby v%s' % RUBY_VERSION

compare do

  _jaredsmith { jaredsmith(array) }
  _lri { lri(array) }
  _finks { finks(array) }

In Java 8, you can now pass a method more easily using Lambda Expressions and Method References. First, some background: a functional interface is an interface that has one and only one abstract method, although it can contain any number of default methods (new in Java 8) and static methods. A lambda expression can quickly implement the abstract method, without all the unnecessary syntax needed if you don't use a lambda expression.

Without lambda expressions:

obj.aMethod(new AFunctionalInterface() {
    @Override
    public boolean anotherMethod(int i)
    {
        return i == 982
    }
});

With lambda expressions:

obj.aMethod(i -> i == 982);

Here is an excerpt from the Java tutorial on Lambda Expressions:

Syntax of Lambda Expressions

A lambda expression consists of the following:

• A comma-separated list of formal parameters enclosed in parentheses. The CheckPerson.test method contains one parameter, p, which represents an instance of the Person class.
  
  Note: You can omit the data type of the parameters in a lambda expression. In addition, you can omit the parentheses if there is only one parameter. For example, the following lambda expression is also valid:

  p -> p.getGender() == Person.Sex.MALE 
      && p.getAge() >= 18
      && p.getAge() <= 25
  

• The arrow token, ->

• A body, which consists of a single expression or a statement block. This example uses the following expression:

  p.getGender() == Person.Sex.MALE 
      && p.getAge() >= 18
      && p.getAge() <= 25
  

  If you specify a single expression, then the Java runtime evaluates the expression and then returns its value. Alternatively, you can use a return statement:

  p -> {
      return p.getGender() == Person.Sex.MALE
          && p.getAge() >= 18
          && p.getAge() <= 25;
  }
  

  A return statement is not an expression; in a lambda expression, you must enclose statements in braces ({}). However, you do not have to enclose a void method invocation in braces. For example, the following is a valid lambda expression:

  email -> System.out.println(email)
  

Note that a lambda expression looks a lot like a method declaration; you can consider lambda expressions as anonymous methods—methods without a name.

Here is how you can "pass a method" using a lambda expression:

interface I {
    public void myMethod(Component component);
}

class A {
    public void changeColor(Component component) {
        // code here
    }

    public void changeSize(Component component) {
        // code here
    }
}

class B {
    public void setAllComponents(Component[] myComponentArray, I myMethodsInterface) {
        for(Component leaf : myComponentArray) {
            if(leaf instanceof Container) { // recursive call if Container
                Container node = (Container)leaf;
                setAllComponents(node.getComponents(), myMethodInterface);
            } // end if node
            myMethodsInterface.myMethod(leaf);
        } // end looping through components
    }
}

class C {
    A a = new A();
    B b = new B();

    public C() {
        b.setAllComponents(this.getComponents(), component -> a.changeColor(component));
        b.setAllComponents(this.getComponents(), component -> a.changeSize(component));
    }
}

Class C can be shortened even a bit further by the use of method references like so:

class C {
    A a = new A();
    B b = new B();

    public C() {
        b.setAllComponents(this.getComponents(), a::changeColor);
        b.setAllComponents(this.getComponents(), a::changeSize);
    }
}

If using a StackTraceElement, use:

String fullClassName = stackTraceElement.getClassName();
String simpleClassName = fullClassName.substring(fullClassName.lastIndexOf('.') + 1);

System.out.println(simpleClassName);

As you can see, it has more capabilities such as the ability to set background color temporarily, indefinitely, and other features. I also believe it is a bit more beginner friendly and easier to remember all of the functions.

#include <iostream>
#include "COLORS.h"

int main() {
  std::cout << SetBackBLU << SetForeRED << endl;
  std::cout << "I am red text on a blue background! :) " << endl;
  return 0;
}

Simply include the header file in your project and you're ready to rock and roll with the colored terminal output.

Easiest and simplest way:

var days = ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"];
var dayName = days[new Date().getDay()];

Nothing compares to extjs in terms of community size and presence on StackOverflow. Despite previous controversy, Ext JS now has a GPLv3 open source license. Its learning curve is long, but it can be quite rewarding once learned. Ext JS lacks a Material Design theme, and the team has repeatedly refused to release the source code on GitHub. For mobile, one must use the separate Sencha Touch library.

Have in mind also that,

large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don’t want to be locked into.

-- Announcement of YUI development being ceased

That said, below are a number of Ext JS alternatives currently available.

Leading client widget libraries

1. Blueprint is a React-based UI toolkit developed by big data analytics company Palantir in TypeScript, and "optimized for building complex data-dense interfaces for desktop applications". Actively developed on GitHub as of May 2019, with comprehensive documentation. Components range from simple (chips, toast, icons) to complex (tree, data table, tag input with autocomplete, date range picker. No accordion or resizer.

   Blueprint targets modern browsers (Chrome, Firefox, Safari, IE 11, and Microsoft Edge) and is licensed under a modified Apache license.

   Sandbox / demo • GitHub • Docs

2. Webix - an advanced, easy to learn, mobile-friendly, responsive and rich free&open source JavaScript UI components library. Webix spun off from DHTMLX Touch (a project with 8 years of development behind it - see below) and went on to become a standalone UI components framework. The GPL3 edition allows commercial use and lets non-GPL applications using Webix keep their license, e.g. MIT, via a license exemption for FLOSS. Webix has 55 UI widgets, including trees, grids, treegrids and charts. Funding comes from a commercial edition with some advanced widgets (Pivot, Scheduler, Kanban, org chart etc.). Webix has an extensive list of free and commercial widgets, and integrates with most popular frameworks (React, Vue, Meteor, etc) and UI components.

   

   Skins look modern, and include a Material Design theme. The Touch theme also looks quite Material Design-ish. See also the Skin Builder.

   Minimal GitHub presence, but includes the library code, and the documentation (which still needs major improvements). Webix suffers from a having a small team and a lack of marketing. However, they have been responsive to user feedback, both on GitHub and on their forum.

   The library was lean (128Kb gzip+minified for all 55 widgets as of ~2015), faster than ExtJS, dojo and others, and the design is pleasant-looking. The current version of Webix (v6, as of Nov 2018) got heavier (400 - 676kB minified but NOT gzipped).

   The demos on Webix.com look and function great. The developer, XB Software, uses Webix in solutions they build for paying customers, so there's likely a good, funded future ahead of it.

   Webix aims for backwards compatibility down to IE8, and as a result carries some technical debt.

3. react-md - MIT-licensed Material Design UI components library for React. Responsive, accessible. Implements components from simple (buttons, cards) to complex (sortable tables, autocomplete, tags input, calendars). One lead author, ~1900 GitHub stars.

4. kendo - jQuery-based UI toolkit with 40+ basic open-source widgets, plus commercial professional widgets (grids, trees, charts etc.). Responsive&mobile support. Works with Bootstrap and AngularJS. Modern, with Material Design themes. The documentation is available on GitHub, which has enabled numerous contributions from users (4500+ commits, 500+ PRs as of Jan 2015).

   

   Well-supported commercially, claiming millions of developers, and part of a large family of developer tools. Telerik has received many accolades, is a multi-national company (Bulgaria, US), was acquired by Progress Software, and is a thought leader.

   A Kendo UI Professional developer license costs $700 and posting access to most forums is conditioned upon having a license or being in the trial period.

5. OpenUI5 - jQuery-based UI framework with 180 widgets, Apache 2.0-licensed and fully-open sourced and funded by German software giant SAP SE.

   

   The community is much larger than that of Webix, SAP is hiring developers to grow OpenUI5, and they presented OpenUI5 at OSCON 2014.

   The desktop themes are rather lackluster, but the Fiori design for web and mobile looks clean and neat.

   Wikipedia • GitHub • Mobile-first controls demos • Desktop controls demos • SO

6. DHTMLX - JavaScript library for building rich Web and Mobile apps. Looks most like ExtJS - check the demos. Has been developed since 2005 but still looks modern. All components except TreeGrid are available under GPLv2 but advanced features for many components are only available in the commercial PRO edition - see for example the tree. Claims to be used by many Fortune 500 companies.

   

   Minimal presence on GitHub (the main library code is missing) and StackOverflow but active forum. The documentation is not available on GitHub, which makes it difficult to improve by the community.

7. Polymer, a Web Components polyfill, plus Polymer Paper, Google's implementation of the Material design. Aimed at web and mobile apps. Doesn't have advanced widgets like trees or even grids but the controls it provides are mobile-first and responsive. Used by many big players, e.g. IBM or USA Today.

   

8. Ant Design claims it is "a design language for background applications", influenced by "nature" and helping designers "create low-entropy atmosphere for developer team". That's probably a poor translation from Chinese for "UI components for enterprise web applications". It's a React UI library written in TypeScript, with many components, from simple (buttons, cards) to advanced (autocomplete, calendar, tag input, table).

   The project was born in China, is popular with Chinese companies, and parts of the documentation are available only in Chinese. Quite popular on GitHub, yet it makes the mistake of splitting the community into Chinese and English chat rooms. The design looks Material-ish, but fonts are small and the information looks lost in a see of whitespace.

9. PrimeUI - collection of 45+ rich widgets based on jQuery UI. Apache 2.0 license. Small GitHub community. 35 premium themes available.

10. qooxdoo - "a universal JavaScript framework with a coherent set of individual components", developed and funded by German hosting provider 1&1 (see the contributors, one of the world's largest hosting companies. GPL/EPL (a business-friendly license).

    Mobile themes look modern but desktop themes look old (gradients).

11. jQuery UI - easy to pick up; looks a bit dated; lacks advanced widgets. Of course, you can combine it with independent widgets for particular needs, e.g. trees or other UI components, but the same can be said for any other framework.

12. angular + Angular UI. While Angular is backed by Google, it's being radically revamped in the upcoming 2.0 version, and "users will need to get to grips with a new kind of architecture. It's also been confirmed that there will be no migration path from Angular 1.X to 2.0". Moreover, the consensus seems to be that Angular 2 won't really be ready for use until a year or two from now. Angular UI has relatively few widgets (no trees, for example).

13. DojoToolkit and their powerful Dijit set of widgets. Completely open-sourced and actively developed on GitHub, but development is now (Nov 2018) focused on the new dojo.io framework, which has very few basic widgets. BSD/AFL license. Development started in 2004 and the Dojo Foundation is being sponsored by IBM, Google, and others - see Wikipedia. 7500 questions here on SO.

    

    Themes look desktop-oriented and dated - see the theme tester in dijit. The official theme previewer is broken and only shows "Claro". A Bootstrap theme exists, which looks a lot like Bootstrap, but doesn't use Bootstrap classes. In Jan 2015, I started a thread on building a Material Design theme for Dojo, which got quite popular within the first hours. However, there are questions regarding building that theme for the current Dojo 1.10 vs. the next Dojo 2.0. The response to that thread shows an active and wide community, covering many time zones.

    Unfortunately, Dojo has fallen out of popularity and fewer companies appear to use it, despite having (had?) a strong foothold in the enterprise world. In 2009-2012, its learning curve was steep and the documentation needed improvements; while the documentation has substantially improved, it's unclear how easy it is to pick up Dojo nowadays.

    With a Material Design theme, Dojo (2.0?) might be the killer UI components framework.

I would recommend a combination of PatIndex and Left. Carefully constructed, you can write a query that always works, no matter what your data looks like.

Ex:

Declare @Temp Table(Data VarChar(20))

Insert Into @Temp Values('BTA200')
Insert Into @Temp Values('BTA50')
Insert Into @Temp Values('BTA030')
Insert Into @Temp Values('BTA')
Insert Into @Temp Values('123')
Insert Into @Temp Values('X999')

Select Data, Left(Data, PatIndex('%[0-9]%', Data + '1') - 1)
From   @Temp

PatIndex will look for the first character that falls in the range of 0-9, and return it's character position, which you can use with the LEFT function to extract the correct data. Note that PatIndex is actually using Data + '1'. This protects us from data where there are no numbers found. If there are no numbers, PatIndex would return 0. In this case, the LEFT function would error because we are using Left(Data, PatIndex - 1). When PatIndex returns 0, we would end up with Left(Data, -1) which returns an error.

There are still ways this can fail. For a full explanation, I encourage you to read:

Extracting numbers with SQL Server

That article shows how to get numbers out of a string. In your case, you want to get alpha characters instead. However, the process is similar enough that you can probably learn something useful out of it.

You can use WhenAll which will return an awaitable Task or WaitAll which has no return type and will block further code execution simular to Thread.Sleep until all tasks are completed, canceled or faulted.

Example

var tasks = new Task[] {
    TaskOperationOne(),
    TaskOperationTwo()
};

Task.WaitAll(tasks);
// or
await Task.WhenAll(tasks);

If you want to run the tasks in a praticular order you can get inspiration form this anwser.

I have read the many comments on this page that complain that using a dom parser is unnecessary overhead. Well, it may be more expensive than a mere regex call, but the OP has stated that there is no control over the order of the attributes in the img tags. This fact leads to unnecessary regex pattern convolution. Beyond that, using a dom parser provides the additional benefits of readability, maintainability, and dom-awareness (regex is not dom-aware).

I love regex and I answer lots of regex questions, but when dealing with valid HTML there is seldom a good reason to regex over a parser.

In the demonstration below, see how easy and clean DOMDocument handles img tag attributes in any order with a mixture of quoting (and no quoting at all). Also notice that tags without a targeted attribute are not disruptive at all -- an empty string is provided as a value.

Code: (Demo)

$test = <<<HTML
<img src="/image/fluffybunny.jpg" title="Harvey the bunny" alt="a cute little fluffy bunny" />
<img src='/image/pricklycactus.jpg' title='Roger the cactus' alt='a big green prickly cactus' />
<p>This is irrelevant text.</p>
<img alt="an annoying white cockatoo" title="Polly the cockatoo" src="/image/noisycockatoo.jpg">
<img title=something src=somethingelse>
HTML;

libxml_use_internal_errors(true);  // silences/forgives complaints from the parser (remove to see what is generated)
$dom = new DOMDocument();
$dom->loadHTML($test);
foreach ($dom->getElementsByTagName('img') as $i => $img) {
    echo "IMG#{$i}:\n";
    echo "\tsrc = " , $img->getAttribute('src') , "\n";
    echo "\ttitle = " , $img->getAttribute('title') , "\n";
    echo "\talt = " , $img->getAttribute('alt') , "\n";
    echo "---\n";
}

Output:

IMG#0:
    src = /image/fluffybunny.jpg
    title = Harvey the bunny
    alt = a cute little fluffy bunny
---
IMG#1:
    src = /image/pricklycactus.jpg
    title = Roger the cactus
    alt = a big green prickly cactus
---
IMG#2:
    src = /image/noisycockatoo.jpg
    title = Polly the cockatoo
    alt = an annoying white cockatoo
---
IMG#3:
    src = somethingelse
    title = something
    alt = 
---

Using this technique in professional code will leave you with a clean script, fewer hiccups to contend with, and fewer colleagues that wish you worked somewhere else.

Think about it this way. If you have a rectangle where one axis is radius and one is angle, and you take the points inside this rectangle that are near radius 0. These will all fall very close to the origin (that is close together on the circle.) However, the points near radius R, these will all fall near the edge of the circle (that is, far apart from each other.)

This might give you some idea of why you are getting this behavior.

The factor that's derived on that link tells you how much corresponding area in the rectangle needs to be adjusted to not depend on the radius once it's mapped to the circle.

Edit: So what he writes in the link you share is, "That’s easy enough to do by calculating the inverse of the cumulative distribution, and we get for r:".

The basic premise is here that you can create a variable with a desired distribution from a uniform by mapping the uniform by the inverse function of the cumulative distribution function of the desired probability density function. Why? Just take it for granted for now, but this is a fact.

Here's my somehwat intuitive explanation of the math. The density function f(r) with respect to r has to be proportional to r itself. Understanding this fact is part of any basic calculus books. See sections on polar area elements. Some other posters have mentioned this.

So we'll call it f(r) = C*r;

This turns out to be most of the work. Now, since f(r) should be a probability density, you can easily see that by integrating f(r) over the interval (0,R) you get that C = 2/R^2 (this is an exercise for the reader.)

Thus, f(r) = 2*r/R^2

OK, so that's how you get the formula in the link.

Then, the final part is going from the uniform random variable u in (0,1) you must map by the inverse function of the cumulative distribution function from this desired density f(r). To understand why this is the case you need to find an advanced probability text like Papoulis probably (or derive it yourself.)

Integrating f(r) you get F(r) = r^2/R^2

To find the inverse function of this you set u = r^2/R^2 and then solve for r, which gives you r = R * sqrt(u)

This totally makes sense intuitively too, u = 0 should map to r = 0. Also, u = 1 shoudl map to r = R. Also, it goes by the square root function, which makes sense and matches the link.

This is probably the most correct, direct replacement: insertAdjacentHTML.

In Ruby Sinatra

response['Access-Control-Allow-Origin'] = '*' 

for everyone or

response['Access-Control-Allow-Origin'] = 'http://yourdomain.name' 

As others suggested, the problem is when windows.h is included before WinSock2.h. Because windows.h includes winsock.h. You can not use both WinSock2.h and winsock.h.

Solutions:

• Include WinSock2.h before windows.h. In the case of precompiled headers, you should solve it there. In the case of simple project, it is easy. However in big projects (especially when writing portable code, without precompiled headers) it can be very hard, because when your header with WinSock2.h is included, windows.h can be already included from some other header/implementation file.

• Define WIN32_LEAN_AND_MEAN before windows.h or project wide. But it will exclude many other stuff you may need and you should include it by your own.

• Define _WINSOCKAPI_ before windows.h or project wide. But when you include WinSock2.h you get macro redefinition warning.

• Use windows.h instead of WinSock2.h when winsock.h is enough for your project (in most cases it is). This will probably result in longer compilation time but solves any errors/warnings.

what @eldarerathis said is correct in all aspects, the wake lock is the right way of keeping the device from going to sleep.

I don't know waht you app needs to do but it is really important that you think on how architect your app so that you don't force the phone to stay awake for more that you need, or the battery life will suffer enormously.

I would point you to this really good example on how to use AlarmManager to fire events and wake up the phone and (your app) to perform what you need to do and then go to sleep again: Alarm Manager (source: commonsware.com)

Uninstalling(version: 2.19.2) and installing(version: 2.21.0) git client fixed the issue for me.

If you have this array:

String [][] example = {{{"Please!", "Thanks"}, {"Hello!", "Hey", "Hi!"}},
                       {{"Why?", "Where?", "When?", "Who?"}, {"Yes!"}}};

You can do this:

example.length;

= 2

example[0].length;

= 2

example[1].length;

= 2

example[0][1].length;

= 3

example[1][0].length;

= 4

In Ubuntu for install imap use

sudo apt-get install php-imap

Ubuntu 14.04 and above use

sudo apt-get install php5-imap

And imap by default not enabled by PHP so use this command to enable imap extension

sudo php5enmod imap

Then restart your Apache

sudo service apache2 restart

I am assuming you have a remote with all relevant changes already pushed to it. I did not care about local changes and simply wanted to avoid deleting and recloning a large repository. If you do have important local changes you might want to be more careful.

I had the same problem after my laptop crashed. Probably because it was a large repository I had quite a few corrupt object files, which only appeared one at a time when calling git fsck --full, so I wrote a small shell one-liner to automatically delete one of them:

$ sudo rm `git fsck --full 2>&1 | grep -oE -m 1 ".git/objects/[0-9a-f]{2}/[0-9a-f]*"`

• 2>&1 redirects the error message to stdout to be able to grep it
• grep options used:
  • -o only returns the part of a line that actually matches
  • -E enables advanced regexes
  • -m 1 make sure only the first match is returned
  • [0-9a-f]{2} matches any of the characters between 0 and 9 and a and f if two of them occur together
  • [0-9a-f]* matches any number of the characters between 0 and 9 and a and f occuring together

It still only deletes one file at a time, so you might want to call it in a loop like:

$ while true; do sudo rm `git fsck --full 2>&1 | grep -oE -m 1 ".git/objects/[0-9a-f]{2}/[0-9a-f]*"`; done

The problem with this is, that it does not output anything useful anymore so you do not know when it is finished (it should just not do anything useful after some time)

To "fix" this I then just added a call of git fsck --full after each round like so: $ while true; do sudo rm `git fsck --full 2>&1 | grep -oE -m 1 ".git/objects/[0-9a-f]{2}/[0-9a-f]*"`; git fsck --full; done

It now is approximately half as fast, but it does output it's "state".

After this I played around some with the suggestions in this thread and finally got to a point where I could git stash and git stash drop a lot of the broken stuff.

first problem solved

Afterwards I still had the following problem: unable to resolve reference 'refs/remotes/origin/$branch': reference broken which could be solved by $ rm \repo.git\refs\remotes\origin\$branch

$ git fetch

I then did a $ git gc --prune=now

$ git remote prune origin

for good measure and

git reflog expire --stale-fix --all

to get rid of error: HEAD: invalid reflog entry $blubb when running git fsck --full.

As mentioned earlier, the __del__ functionality is somewhat unreliable. In cases where it might seem useful, consider using the __enter__ and __exit__ methods instead. This will give a behaviour similar to the with open() as f: pass syntax used for accessing files. __enter__ is automatically called when entering the scope of with, while __exit__ is automatically called when exiting it. See this question for more details.

Any JS code which executes and deals with DOM elements should execute after the DOM elements have been created. JS code is interpreted from top to down as layed out in the HTML. So, if there is a tag before the DOM elements, the JS code within script tag will execute as the browser parses the HTML page.

So, in your case, you can put your DOM interacting code inside a function so that only function is defined but not executed.

Then you can add an event listener for document load to execute the function.

That will give you something like:

<script>
  function init() {
    var myButton = document.getElementById("myButton");
    var myTextfield = document.getElementById("myTextfield");
    myButton.onclick = function() {
      var userName = myTextfield.value;
      greetUser(userName);
    }
  }

  function greetUser(userName) {
    var greeting = "Hello " + userName + "!";
    document.getElementsByTagName ("h2")[0].innerHTML = greeting;
  }

  document.addEventListener('readystatechange', function() {
    if (document.readyState === "complete") {
      init();
    }
  });

</script>
<h2>Hello World!</h2>
<p id="myParagraph">This is an example website</p>

<form>
  <input type="text" id="myTextfield" placeholder="Type your name" />
  <input type="button" id="myButton" value="Go" />
</form>

Fiddle at - http://jsfiddle.net/poonia/qQMEg/4/

if [ -z "$(ls -lA)" ]; then
  echo "no files found"
else
  echo "There are files"
fi

This will run the command and check whether the returned output (string) has a zero length. You might want to check the 'test' manual pages for other flags.

Use the "" around the argument that is being checked, otherwise empty results will result in a syntax error as there is no second argument (to check) given!

Note: that ls -la always returns . and .. so using that will not work, see ls manual pages. Furthermore, while this might seem convenient and easy, I suppose it will break easily. Writing a small script/application that returns 0 or 1 depending on the result is much more reliable!

Set CSS display property to none.

document.getElementById("test").style.display = "none";

Also, you do not need javascript: for the onclick attribute.

<input type="image" src="../images/btnFind.png" id="find" name="find" 
    onclick="hide();" />

Finally, make sure you do not have multiple elements with the same ID.

If your form goes nowhere, Phil suggested that you should prevent submission of the form. Simply return false in the onsubmit handler.

<form method="post" id="test" onsubmit="return false;">

If you want the form to post, but hide the div on subsequent page load, you will have to use server-side code to hide the element:

<script type="text/javascript">
function hide() {
    document.getElementById("test").style.display = "none";
}
window.onload = function() {
    // if form was submitted, PHP will print the below,

}
</script>

The main issue with your example that you can't implicitly convert Task<T> return types to the base T type. You need to use the Task.Result property. Note that Task.Result will block async code, and should be used carefully.

Try this instead:

public List<int> TestGetMethod()  
{  
    return GetIdList().Result;  
}

Vector was part of 1.0 -- the original implementation had two drawbacks:

1. Naming: vectors are really just lists which can be accessed as arrays, so it should have been called ArrayList (which is the Java 1.2 Collections replacement for Vector).

2. Concurrency: All of the get(), set() methods are synchronized, so you can't have fine grained control over synchronization.

There is not much difference between ArrayList and Vector, but you should use ArrayList.

From the API doc.

As of the Java 2 platform v1.2, this class was retrofitted to implement the List interface, making it a member of the Java Collections Framework. Unlike the new collection implementations, Vector is synchronized.

If you feel like having a simple gui to fix this (as I do), then I can recommend the mongodb pref-pane. Description: https://www.mongodb.com/blog/post/macosx-preferences-pane-for-mongodb

Make sure you've placed the connection string in the startup project's ROOT web.config.

I know I'm kinda stating the obvious here, but it happened to me too - though I already HAD the connection string in my MVC project's Web.Config (the .edmx file was placed at a different, class library project) and I couldn't figure out why I keep getting an exception... Long story short, I copied the connection string to the Views\Web.Config by mistake, in a strange combination of tiredness and not-scrolling-to-the-bottom-of-the-solution-explorer scenario. Yeah, these things happen to veteran developers as well :)

I will correct usage for that method that @BullyWillPlaza suggested. Reason is that when I try to add add textArea to only contextMenu it's not visible, and if i add it to both to contextMenu and some panel it ecounters: Different parent double association if i try to switch to Design editor.

TexetObjcet.addMouseListener(new MouseAdapter() {
        @Override
        public void mouseClicked(MouseEvent e) {
            if (SwingUtilities.isRightMouseButton(e)){
                contextmenu.add(TexetObjcet);
                contextmenu.show(TexetObjcet, 0, 0);
            }
        }
    }); 

Make mouse listener like this for text object you need to have popup on. What this will do is when you right click on your text object it will then add that popup and display it. This way you don't encounter that error. Solution that @BullyWillPlaza made is very good, rich and fast to implement in your program so you should try it our see how you like it.

In addition to move_to_element() and scrollIntoView() I wanted to pose the following code which attempts to center the element in the view:

desired_y = (element.size['height'] / 2) + element.location['y']
window_h = driver.execute_script('return window.innerHeight')
window_y = driver.execute_script('return window.pageYOffset')
current_y = (window_h / 2) + window_y
scroll_y_by = desired_y - current_y

driver.execute_script("window.scrollBy(0, arguments[0]);", scroll_y_by)

First you need to get the current date

var currentDate = new Date();

Then you need to place it in the arguments of datepicker like given below

$("#datepicker").datepicker("setDate", currentDate);

Check the following jsfiddle.

You can use extend method in list operations as well.

>>> list1 = []
>>> list1.extend('somestring')
>>> list1
['s', 'o', 'm', 'e', 's', 't', 'r', 'i', 'n', 'g']

Bash does not support multidimensional arrays.

You can simulate it though by using indirect expansion:

#!/bin/bash
declare -a a0=(1 2 3 4)
declare -a a1=(5 6 7 8)
var="a1[1]"
echo ${!var}  # outputs 6

Assignments are also possible with this method:

let $var=55
echo ${a1[1]}  # outputs 55

Edit 1: To read such an array from a file, with each row on a line, and values delimited by space, use this:

idx=0
while read -a a$idx; do
    let idx++;
done </tmp/some_file

Edit 2: To declare and initialize a0..a3[0..4] to 0, you could run:

for i in {0..3}; do
    eval "declare -a a$i=( $(for j in {0..4}; do echo 0; done) )"
done

I had the exact same problem — fix was babel-preset-react-native-stage-0, instead of babel-preset-react-native.

You may try this:

public static void main(String[] args) {
    BigDecimal a = new BigDecimal("10.12345");
    System.out.println(toPrecision(a, 2));
}

private static BigDecimal toPrecision(BigDecimal dec, int precision) {
    String plain = dec.movePointRight(precision).toPlainString();
    return new BigDecimal(plain.substring(0, plain.indexOf("."))).movePointLeft(precision);
}

OUTPUT:

10.12

Actions

ADD_PRODUCT : (context,product) => {
  return Axios.post(uri, product).then((response) => {
    if (response.status === 'success') {  
      context.commit('SET_PRODUCT',response.data.data)
    }
    return response.data
  });
});

Component

this.$store.dispatch('ADD_PRODUCT',data).then((res) => {
  if (res.status === 'success') {
    // write your success actions here....
  } else {
     // write your error actions here...
  }
})

$('#Crd').val() will give you the selected value of the drop down element. Use this to get the selected options text.

$('#Crd option:selected').text();

CotEditor is a Cocoa-based open source text editor. It is popular in Japan.

Take note that if you have multiple versions of Python installed on your computer, you may have a few versions of pip associated with each.

Depending on your associations, you might need to be very cautious of what pip command you use:

pip3 list 

Worked for me, where I'm running Python3.4. Simply using pip list returned the error The program 'pip' is currently not installed. You can install it by typing: sudo apt-get install python-pip.

As the "GNU C Library Reference Manual" says

off_t
    This is a signed integer type used to represent file sizes. 
    In the GNU C Library, this type is no narrower than int.
    If the source is compiled with _FILE_OFFSET_BITS == 64 this 
    type is transparently replaced by off64_t.

and

off64_t
    This type is used similar to off_t. The difference is that 
    even on 32 bit machines, where the off_t type would have 32 bits,
    off64_t has 64 bits and so is able to address files up to 2^63 bytes
    in length. When compiling with _FILE_OFFSET_BITS == 64 this type 
    is available under the name off_t.

Thus if you want reliable way of representing file size between client and server, you can:

1. Use off64_t type and stat64() function accordingly (as it fills structure stat64, which contains off64_t type itself). Type off64_t guaranties the same size on 32 and 64 bit machines.
2. As was mentioned before compile your code with -D_FILE_OFFSET_BITS == 64 and use usual off_t and stat().
3. Convert off_t to type int64_t with fixed size (C99 standard). Note: (my book 'C in a Nutshell' says that it is C99 standard, but optional in implementation). The newest C11 standard says:

7.20.1.1 Exact-width integer types

    1 The typedef name intN_t designates a signed integer type with width N ,
    no padding bits, and a two’s complement representation. Thus, int8_t 
    denotes such a signed integer type with a width of exactly 8 bits.
    without mentioning.

And about implementation:

7.20 Integer types <stdint.h>

    ... An implementation shall provide those types described as ‘‘required’’,
    but need not provide any of the others (described as ‘‘optional’’).
    ...
    The following types are required:
    int_least8_t  uint_least8_t
    int_least16_t uint_least16_t
    int_least32_t uint_least32_t
    int_least64_t uint_least64_t
    All other types of this form are optional.

Thus, in general, C standard can't guarantee types with fixed sizes. But most compilers (including gcc) support this feature.

I searched quickly for you, and it brought me here. I quote:

You will get this message if you're trying to add a constraint with a name that's already used somewhere else

To check constraints use the following SQL query:

SELECT
    constraint_name,
    table_name
FROM
    information_schema.table_constraints
WHERE
    constraint_type = 'FOREIGN KEY'
AND table_schema = DATABASE()
ORDER BY
    constraint_name;

Look for more information there, or try to see where the error occurs. Looks like a problem with a foreign key to me.

Use an XDocument to create the DOM, then write it out using an XmlWriter. This will give you a wonderfully concise and readable notation as well as nicely formatted output.

Take this sample program:

using System.Xml;
using System.Xml.Linq;

class Program {
    static void Main() {
        var xDocument = new XDocument(
            new XDocumentType("html", null, null, null),
            new XElement("html",
                new XElement("head"),
                new XElement("body",
                    new XElement("p",
                        "This paragraph contains ", new XElement("b", "bold"), " text."
                    ),
                    new XElement("p",
                        "This paragraph has just plain text."
                    )
                )
            )
        );

        var settings = new XmlWriterSettings {
            OmitXmlDeclaration = true, Indent = true, IndentChars = "\t"
        };
        using (var writer = XmlWriter.Create(@"C:\Users\wolf\Desktop\test.html", settings)) {
            xDocument.WriteTo(writer);
        }
    }
}

This generates the following output:

<!DOCTYPE html >
<html>
    <head />
    <body>
        <p>This paragraph contains <b>bold</b> text.</p>
        <p>This paragraph has just plain text.</p>
    </body>
</html>

So I liked a lot of the answers above, but I was looking for something that was a little more random in nature. I also wanted a way to explicitly call out excluded characters. Below is my solution using a view that calls the CRYPT_GEN_RANDOM to get a cryptographic random number. In my example, I only chose a random number that was 8 bytes. Please note, you can increase this size and also utilize the seed parameter of the function if you want. Here is the link to the documentation: https://docs.microsoft.com/en-us/sql/t-sql/functions/crypt-gen-random-transact-sql

CREATE VIEW [dbo].[VW_CRYPT_GEN_RANDOM_8]
AS
SELECT CRYPT_GEN_RANDOM(8) as [value];

The reason for creating the view is because CRYPT_GEN_RANDOM cannot be called directly from a function.

From there, I created a scalar function that accepts a length and a string parameter that can contain a comma delimited string of excluded characters.

CREATE FUNCTION [dbo].[fn_GenerateRandomString]
( 
    @length INT,
    @excludedCharacters VARCHAR(200) --Comma delimited string of excluded characters
)
RETURNS VARCHAR(Max)
BEGIN
    DECLARE @returnValue VARCHAR(Max) = ''
        , @asciiValue INT
        , @currentCharacter CHAR;

    --Optional concept, you can add default excluded characters
    SET @excludedCharacters = CONCAT(@excludedCharacters,',^,*,(,),-,_,=,+,[,{,],},\,|,;,:,'',",<,.,>,/,`,~');

    --Table of excluded characters
    DECLARE @excludedCharactersTable table([asciiValue] INT);

    --Insert comma
    INSERT INTO @excludedCharactersTable SELECT 44;

    --Stores the ascii value of the excluded characters in the table
    INSERT INTO @excludedCharactersTable
    SELECT ASCII(TRIM(value))
    FROM STRING_SPLIT(@excludedCharacters, ',')
    WHERE LEN(TRIM(value)) = 1;

    --Keep looping until the return string is filled
    WHILE(LEN(@returnValue) < @length)
    BEGIN
        --Get a truly random integer values from 33-126
        SET @asciiValue = (SELECT TOP 1 (ABS(CONVERT(INT, [value])) % 94) + 33 FROM [dbo].[VW_CRYPT_GEN_RANDOM_8]);

        --If the random integer value is not in the excluded characters table then append to the return string
        IF(NOT EXISTS(SELECT * 
                        FROM @excludedCharactersTable 
                        WHERE [asciiValue] = @asciiValue))
        BEGIN
            SET @returnValue = @returnValue + CHAR(@asciiValue);
        END
    END

    RETURN(@returnValue);
END

Below is an example of the how to call the function.

SELECT [dbo].[fn_GenerateRandomString](8,'!,@,#,$,%,&,?');

The title of the question asks about precision. BigDecimal distinguishes between scale and precision. Scale is the number of decimal places. You can think of precision as the number of significant figures, also known as significant digits.

Some examples in Clojure.

(.scale     0.00123M) ; 5
(.precision 0.00123M) ; 3

(In Clojure, The M designates a BigDecimal literal. You can translate the Clojure to Java if you like, but I find it to be more compact than Java!)

You can easily increase the scale:

(.setScale 0.00123M 7) ; 0.0012300M

But you can't decrease the scale in the exact same way:

(.setScale 0.00123M 3) ; ArithmeticException Rounding necessary

You'll need to pass a rounding mode too:

(.setScale 0.00123M 3 BigDecimal/ROUND_HALF_EVEN) ;
; Note: BigDecimal would prefer that you use the MathContext rounding
; constants, but I don't have them at my fingertips right now.

So, it is easy to change the scale. But what about precision? This is not as easy as you might hope!

It is easy to decrease the precision:

(.round 3.14159M (java.math.MathContext. 3)) ; 3.14M

But it is not obvious how to increase the precision:

(.round 3.14159M (java.math.MathContext. 7)) ; 3.14159M (unexpected)

For the skeptical, this is not just a matter of trailing zeros not being displayed:

(.precision (.round 3.14159M (java.math.MathContext. 7))) ; 6 
; (same as above, still unexpected)

FWIW, Clojure is careful with trailing zeros and will show them:

4.0000M ; 4.0000M
(.precision 4.0000M) ; 5

Back on track... You can try using a BigDecimal constructor, but it does not set the precision any higher than the number of digits you specify:

(BigDecimal. "3" (java.math.MathContext. 5)) ; 3M
(BigDecimal. "3.1" (java.math.MathContext. 5)) ; 3.1M

So, there is no quick way to change the precision. I've spent time fighting this while writing up this question and with a project I'm working on. I consider this, at best, A CRAZYTOWN API, and at worst a bug. People. Seriously?

So, best I can tell, if you want to change precision, you'll need to do these steps:

1. Lookup the current precision.
2. Lookup the current scale.
3. Calculate the scale change.
4. Set the new scale

These steps, as Clojure code:

(def x 0.000691M) ; the input number
(def p' 1) ; desired precision
(def s' (+ (.scale x) p' (- (.precision x)))) ; desired new scale
(.setScale x s' BigDecimal/ROUND_HALF_EVEN)
; 0.0007M

I know, this is a lot of steps just to change the precision!

Why doesn't BigDecimal already provide this? Did I overlook something?

Have a look at the below code snippet.

@RequestMapping(value="/Add/{type}")
public ModelAndView addForm(@PathVariable String type ){
    ModelAndView modelAndView = new ModelAndView();
    modelAndView.setViewName("addContent");
    modelAndView.addObject("typelist",contentPropertyDAO.getType() );
    modelAndView.addObject("property",contentPropertyDAO.get(type,0) );
    return modelAndView;
}

Hope it helps in constructing your code.

wouldn't

margin-left:auto;
margin-right:auto;

added to the .image_block a img do the trick?
Note that that won't work in IE6 (maybe 7 not sure)
there you will have to do on .image_block the container Div

text-align:center;

position:relative; could be a problem too.

button2.Enabled == true ;

should be

button2.Enabled = true ;

In case you have key value pairs in your input array, I used:

.filter(
          this.multi_items[0] != null && store.state.isSearchBox === false
            ? item =>
                _.map(this.multi_items, "value").includes(item["wijknaam"])
            : item => item["wijknaam"].includes("")
        );

where the input array is multi_items as: [{"text": "bla1", "value": "green"}, {"text": etc. etc.}]

_.map is a lodash function.

Did you write return true somewhere? You should have written it, otherwise function returns nothing and program may think that it's false, too.

function isValid(str) {
    var iChars = "~`!#$%^&*+=-[]\\\';,/{}|\":<>?";

    for (var i = 0; i < str.length; i++) {
       if (iChars.indexOf(str.charAt(i)) != -1) {
           alert ("File name has special characters ~`!#$%^&*+=-[]\\\';,/{}|\":<>? \nThese are not allowed\n");
           return false;
       }
    }
    return true;
}

I tried this in my chrome console and it worked well.

There are two different ways of importing components in react and the recommended way is component way

1. Library way(not recommended)
2. Component way(recommended)

PFB detail explanation

Library way of importing

import { Button } from 'react-bootstrap';
import { FlatButton } from 'material-ui';

This is nice and handy but it does not only bundles Button and FlatButton (and their dependencies) but the whole libraries.

Component way of importing

One way to alleviate it is to try to only import or require what is needed, lets say the component way. Using the same example:

import Button from 'react-bootstrap/lib/Button';
import FlatButton from 'material-ui/lib/flat-button';

This will only bundle Button, FlatButton and their respective dependencies. But not the whole library. So I would try to get rid of all your library imports and use the component way instead.

If you are not using lot of components then it should reduce considerably the size of your bundled file.

There is two way you can define cell. If your table cell is inside on your ViewControllern then get the cell this way:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCell", for: indexPath) as! TableViewCell
        // write your code here 
        return cell
}

But if you define cell outside of your ViewController then call the sell this way:

 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = Bundle.main.loadNibNamed("TableViewCell", owner: self, options: nil)?.first as! TableViewCell
        // write your code here
        return cell
    }

And as everyone said don't forget to set your cell identifier:

Why not just simplify it to if($_GET['id']). It will return true or false depending on status of the parameter's existence.

I encountered this error when inheriting from an abstract class and not implementing all of the pure virtual methods in my subclass.

The accepted answer is wrong. GET requests can indeed contain a body. This is the solution implemented by WordPress, as an example:

curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, 'GET' );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $body );

EDIT: To clarify, the initial curl_setopt is necessary in this instance, because libcurl will default the HTTP method to POST when using CURLOPT_POSTFIELDS (see documentation).

This is one way I know of. With git, there always seems to be more than one way to do it.

git log -p commit1 commit2

You can try the same with replacewith()

$('.click').click(function() {
    // get the contents of the link that was clicked
    var linkText = $(this).text();

    // replace the contents of the div with the link text
    $('#content-container').replaceWith(linkText);

    // cancel the default action of the link by returning false
    return false;
});

The .replaceWith() method removes content from the DOM and inserts new content in its place with a single call.

The two methods are 100% equivalent.

I’m not sure why Microsoft felt the need to include this extra Clear method but since it’s there, I recommend using it, as it clearly expresses its purpose.

Here is the tutorial to install GBD.

Usually GNU Debugger might not be in your computer, so you would install it first. The installation steps are basic "configure", "make", and "make install".

Once installed, try which gdb in terminal, to find the executable path of GDB.

Force closing a file after using numpy.load:

A niche usage perhaps but I found it useful when using numpy.load to read a file. Every once in a while I would update the file and need to copy a file with the same name to the directory.

I used del to release the file and allow me to copy in the new file.

Note I want to avoid the with context manager as I was playing around with plots on the command line and didn't want to be pressing tab a lot!

See this question.

I was struggling for a while with this as my work computer (with Windows 10) created the default user library on a network drive, which would slow down R and RStudio to an unusable state.

In case this helps someone, this is the easiest way I found, without requiring admin rights:

• make sure the directory you want to install your packages into exists. If you want to respect the convention, use: C:\Users\username\R\win-library\rversion (for example, something like: C:\Users\janebloggs\R\win-library\3.6)
• create a .Renviron file in your home directory (which might be on the network drive?), and in it, write one single line that defines the R_LIBS_USER variable to be your custom path:

R_LIBS_USER=C:\Users\janebloggs\R\win-library\3.6

(feel free to add comments too, with lines starting with #)

If a .Renviron file exists, R will read it at startup and use the variables as they are defined in there, before running the code in the .Rprofile. You can read about it in help(Startup).

Now it should be persistent between sessions!

Your for loop is wrong. Try :

for(int a = 0, b = 1; a<cards.length()-1; b=a+1, a++){

Also, System instead of system and == instead of ===.

But I'm not sure what you're trying to do.

I'm not sure there's a way to hide that information. No matter what you do to obfuscate or hide whatever you're doing in JavaScript, it still comes down to the fact that your browser needs to load it in order to use it. Modern browsers have web debugging/analysis tools out of the box that make extracting and viewing scripts trivial (just hit F12 in Chrome, for example).

If you're worried about exposing some kind of trade secret or algorithm, then your only recourse is to encapsulate that logic in a web service call and have your page invoke that functionality via AJAX.

If all the previous answers didn't give any solution, you should check your user privileges.

If you could login as root to mysql then you should add this:

CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY  '***';
GRANT ALL PRIVILEGES ON * . * TO  'root'@'192.168.1.100' IDENTIFIED BY  '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100. It should work.

Question has a good pagerank on google, so for anyone who's looking for answer to this question this might be helpful.

There is an extension in google chrome marketspace to do exactly that: https://chrome.google.com/webstore/detail/hccmhjmmfdfncbfpogafcbpaebclgjcp

Another solution

Here is a new solution based on Bennett McElwee answer in the same question as mentioned below.

Tested with IE 9 & 10, Opera 12.01, Google Chrome 22 and Firefox 15.0.
jsFiddle example

1.) Add this CSS to your site:

@media screen {
  #printSection {
      display: none;
  }
}

@media print {
  body * {
    visibility:hidden;
  }
  #printSection, #printSection * {
    visibility:visible;
  }
  #printSection {
    position:absolute;
    left:0;
    top:0;
  }
}

2.) Add my JavaScript function

function printElement(elem, append, delimiter) {
    var domClone = elem.cloneNode(true);

    var $printSection = document.getElementById("printSection");

    if (!$printSection) {
        $printSection = document.createElement("div");
        $printSection.id = "printSection";
        document.body.appendChild($printSection);
    }

    if (append !== true) {
        $printSection.innerHTML = "";
    }

    else if (append === true) {
        if (typeof (delimiter) === "string") {
            $printSection.innerHTML += delimiter;
        }
        else if (typeof (delimiter) === "object") {
            $printSection.appendChild(delimiter);
        }
    }

    $printSection.appendChild(domClone);
}?

You're ready to print any element on your site!
Just call printElement() with your element(s) and execute window.print() when you're finished.

Note: If you want to modify the content before it is printed (and only in the print version), checkout this example (provided by waspina in the comments): http://jsfiddle.net/95ezN/121/

One could also use CSS in order to show the additional content in the print version (and only there).

Former solution

I think, you have to hide all other parts of the site via CSS.

It would be the best, to move all non-printable content into a separate DIV:

<body>
  <div class="non-printable">
    <!-- ... -->
  </div>

  <div class="printable">
    <!-- Modal dialog comes here -->
  </div>
</body>

And then in your CSS:

.printable { display: none; }

@media print
{
    .non-printable { display: none; }

There is one problem in using JavaScript: the user cannot see a preview - at least in Internet Explorer!

et.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {

            et.setHint(temp +" Characters");
        }
    });

Try sprintf() for javascript.

Or

// First, checks if it isn't implemented yet.
if (!String.prototype.format) {
  String.prototype.format = function() {
    var args = arguments;
    return this.replace(/{(\d+)}/g, function(match, number) { 
      return typeof args[number] != 'undefined'
        ? args[number]
        : match
      ;
    });
  };
}

"{0} is dead, but {1} is alive! {0} {2}".format("ASP", "ASP.NET")

Both answers pulled from JavaScript equivalent to printf/string.format

First, your jQuery will not work at all unless you enclose all your trs and tds in a table:

<table>
    <tr>...</tr>
    ...
</table>

Second, your code gets the id of the first tr of the page, since you select all the trs of the page and get the id of the first one (.attr() returns the attribute of the first element in the set of elements it is used on)

Your current code:

  $('input[type=button]' ).click(function() {
   bid = (this.id) ; // button ID 
   trid = $('tr').attr('id'); // ID of the the first TR on the page
                              // $('tr') selects all trs in the DOM
  });

trid is always TEST1 (jsFiddle)

Instead of selecting all trs on the page with $('tr'), you want to select the first ancestor of the clicked upon input that is a tr. Use .closest() for this in the form $(this).closest('tr').

You can reference the clicked on element as this, make a jQuery object out of it with the form $(this), so you have access to all the jQuery methods on it.

What your code should look like:

  // On DOM ready...
$(function() {

      $('input[type=button]' ).click(function() {

          var bid, trid; // Declare variables. If you don't use var 
                         // you will bind bid and trid 
                         // to the window, since you make them global variables.

          bid = (this.id) ; // button ID 

          trid = $(this).closest('tr').attr('id'); // table row ID 
      });
});

If re-starting Eclipse does not correct the problem, make sure that the image name begins with an alpha character (non-numeric).

The numbers generated by

=NORMINV(RAND(),10,7)

are uniformally distributed. If you want the numbers to be normally distributed, you will have to write a function I guess.

In case you need to find documents which contain NULL elements inside an array of sub-documents, I've found this query which works pretty well:

db.collection.find({"keyWithArray":{$elemMatch:{"$in":[null], "$exists":true}}})

This query is taken from this post: MongoDb query array with null values

It was a great find and it works much better than my own initial and wrong version (which turned out to work fine only for arrays with one element):

.find({
    'MyArrayOfSubDocuments': { $not: { $size: 0 } },
    'MyArrayOfSubDocuments._id': { $exists: false }
})

If you are using Android Studio 3.0, add the Google maven repository as shown below:

allprojects {
  repositories {
    jcenter()
    google()
 }
}

There's a lot of misunderstanding being displayed here. Unicode isn't an encoding, but the Unicode standard is devoted primarily to encoding anyway.

ISO 10646 is the international character set you (probably) care about. It defines a mapping between a set of named characters (e.g., "Latin Capital Letter A" or "Greek small letter alpha") and a set of code points (a number assigned to each -- for example, 61 hexadecimal and 3B1 hexadecimal for those two respectively; for Unicode code points, the standard notation would be U+0061 and U+03B1).

At one time, Unicode defined its own character set, more or less as a competitor to ISO 10646. That was a 16-bit character set, but it was not UTF-16; it was known as UCS-2. It included a rather controversial technique to try to keep the number of necessary characters to a minimum (Han Unification -- basically treating Chinese, Japanese and Korean characters that were quite a bit alike as being the same character).

Since then, the Unicode consortium has tacitly admitted that that wasn't going to work, and now concentrate primarily on ways to encode the ISO 10646 character set. The primary methods are UTF-8, UTF-16 and UCS-4 (aka UTF-32). Those (except for UTF-8) also have LE (little endian) and BE (big-endian) variants.

By itself, "Unicode" could refer to almost any of the above (though we can probably eliminate the others that it shows explicitly, such as UTF-8). Unqualified use of "Unicode" probably happens the most often on Windows, where it will almost certainly refer to UTF-16. Early versions of Windows NT adopted Unicode when UCS-2 was current. After UCS-2 was declared obsolete (around Win2k, if memory serves), they switched to UTF-16, which is the most similar to UCS-2 (in fact, it's identical for characters in the "basic multilingual plane", which covers a lot, including all the characters for most Western European languages).

There are much nicer ways to do it.

1. Install Nuget.Build package in you project that you want to pack. May need to close and re-open solution after install.

2. Install nuget via chocolatey - much nicer. Install chocolatey: https://chocolatey.org/, then run

   cinst Nuget.CommandLine

in your command prompt. This will install nuget and setup environment paths, so nuget is always available.

Simply write

style="border:medium double;"

for the html tag

Actually the XSD is XML itself. Its purpose is to validate the structure of another XML document. The XSD is not mandatory for any XML, but it assures that the XML could be used for some particular purposes. The XML is only containing data in suitable format and structure.

This approach always works for me:

String newLine = System.getProperty("line.separator");
String textInNewLine = "this is my first line " + newLine + "this is my second 
line ";

The following XSL code will produce a newline (line feed) character:

<xsl:text>&#xa;</xsl:text>

For a carriage return, use:

<xsl:text>&#xd;</xsl:text>

You could use list.indexOf(Object) bug in all honesty what you're describing sounds like you'd be better off using a Map.

Try this:

Map<String, Object> mapOfObjects = new HashMap<String, Object>();
mapOfObjects.put("objectName", object);

Then later when you want to retrieve the object, use

mapOfObjects.get("objectName");

Assuming you do know the object's name as you stated, this will be both cleaner and will have faster performance besides, particularly if the map contains large numbers of objects.

If you need the objects in the Map to stay in order, you can use

Map<String, Object> mapOfObjects = new LinkedHashMap<String, Object>();

instead

This uses twitter bootstrap 3.x with one css class to get labels to sit on top of the inputs. Here's a fiddle link, make sure to expand results panel wide enough to see effect.

HTML:

  <div class="row myform">
     <div class="col-md-12">
        <form name="myform" role="form" novalidate>
           <div class="form-group">
              <label class="control-label" for="fullName">Address Line</label>
              <input required type="text" name="addr" id="addr" class="form-control" placeholder="Address"/>
           </div>

           <div class="form-inline">
              <div class="form-group">
                 <label>State</label>
                 <input required type="text" name="state" id="state" class="form-control" placeholder="State"/>
              </div>

              <div class="form-group">
                 <label>ZIP</label>
                 <input required type="text" name="zip" id="zip" class="form-control" placeholder="Zip"/>
              </div>
           </div>

           <div class="form-group">
              <label class="control-label" for="country">Country</label>
              <input required type="text" name="country" id="country" class="form-control" placeholder="country"/>
           </div>
        </form>
     </div>
  </div>

CSS:

.myform input.form-control {
   display: block;  /* allows labels to sit on input when inline */
   margin-bottom: 15px; /* gives padding to bottom of inline inputs */
}

If you want a complete backup, you will need to perform a few steps:

1. Commit the container to an image
2. Save the image
3. Backup the container's volume by creating a tar file of the volume's mount point in the container.
4. Repeat steps 1-3 for the database container as well.

Note that doing just a Docker commit of the container to an image does NOT include volumes attached to the container (ref: Docker commit documentation).

"The commit operation will not include any data contained in volumes mounted inside the container."

I found it easier to just take over the template from Bootstrap-ui. I have left the commented HTML still in-place to show what I changed.

Overwrite their default template:

<script type="text/ng-template" id="myDlgTemplateWrapper.html">
    <div tabindex="-1" role="dialog" class="modal fade" ng-class="{in: animate}" 
         ng-style="{'z-index': 1050 + index*10, display: 'block'}" ng-click="close($event)"> 
        <!-- <div class="modal-dialog"
            ng-class="{'modal-sm': size == 'sm', 'modal-lg': size == 'lg'}"
            >
            <div class="modal-content"  modal-transclude></div>
        </div>--> 

        <div modal-transclude>
            <!-- Your content goes here -->
        </div>
    </div>
</script>

Modify your dialog template (note the wrapper DIVs containing "modal-dialog" class and "modal-content" class):

<script type="text/ng-template" id="myModalContent.html">
    <div class="modal-dialog {{extraDlgClass}}"
         style="width: {{width}}; max-width: {{maxWidth}}; min-width: {{minWidth}}; ">
        <div class="modal-content">
            <div class="modal-header bg-primary">
                <h3>I am a more flexible modal!</h3>
            </div>
            <div class="modal-body"
                 style="min-height: {{minHeight}}; height: {{height}}; max-height {{maxHeight}}; ">
                <p>Make me any size you want</p>
            </div>
            <div class="modal-footer">
                <button class="btn btn-primary" ng-click="ok()">OK</button>
                <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
            </div>
        </div>
    </div>
</script>

And then call the modal with whatever CSS class or style parameters you wish to change (assuming you have already defined "app" somewhere else):

<script type="text/javascript">
    app.controller("myTest", ["$scope", "$modal", function ($scope, $modal)
    {
        //  Adjust these with your parameters as needed

        $scope.extraDlgClass = undefined;

        $scope.width = "70%";
        $scope.height = "200px";
        $scope.maxWidth = undefined;
        $scope.maxHeight = undefined;
        $scope.minWidth = undefined;
        $scope.minHeight = undefined;

        $scope.open = function ()
        {
            $scope.modalInstance = $modal.open(
            {
                backdrop: 'static',
                keyboard: false,
                modalFade: true,

                templateUrl: "myModalContent.html",
                windowTemplateUrl: "myDlgTemplateWrapper.html",
                scope: $scope,
                //size: size,   - overwritten by the extraDlgClass below (use 'modal-lg' or 'modal-sm' if desired)

                extraDlgClass: $scope.extraDlgClass,

                width: $scope.width,
                height: $scope.height,
                maxWidth: $scope.maxWidth,
                maxHeight: $scope.maxHeight,
                minWidth: $scope.minWidth,
                minHeight: $scope.minHeight
            });

            $scope.modalInstance.result.then(function ()
            {
                console.log('Modal closed at: ' + new Date());
            },
            function ()
            {
                console.log('Modal dismissed at: ' + new Date());
            });
        };

        $scope.ok = function ($event)
        {
            if ($event)
                $event.preventDefault();
            $scope.modalInstance.close("OK");
        };

        $scope.cancel = function ($event)
        {
            if ($event)
                $event.preventDefault();
            $scope.modalInstance.dismiss('cancel');
        };

        $scope.openFlexModal = function ()
        {
            $scope.open();
        }

    }]);
</script>

Add an "open" button and fire away.

    <button ng-controller="myTest" class="btn btn-default" type="button" ng-click="openFlexModal();">Open Flex Modal!</button>

Now you can add whatever extra class you want, or simply change width/height sizes as necessary.

I further enclosed it within a wrapper directive, which is should be trivial from this point forward.

Cheers.

I had the same issue: if I doubleclick on a jar executable file, and my Java application does not start.

So tried to change manually also registry key, but it didn't help me. Tried to reinstall JDK newer/older without any result. (I have several versions of Java)

And I've solved it only using jarfix program. Jarfix automatically fixed .jar association problem on Windows system. (check regedit: PC\HKEY_CLASSES_ROOT\jarfile\shell\open\command)

What says Johann Nepomuk Löfflmann:

The root cause for the problem above is, that a program has stolen the .jar association. If you have installed the Java Runtime Environment the first time, the file type called "jar" is assigned to javaw.exe correctly. "jar" is an abbreviation for "java archive" and javaw.exe is the correct program to execute a .jar. However, on Windows any program can steal a file type at any time even if it is already associated with a program. Many zip/unzip programs prefer to do this, because a jar is stored in the .zip format. If you doubleclick on a .jar, your pack program opens the file, rather than javaw runs the program, because your pack program ignores the meta information which are also stored in a .jar. In the Oracle bug database there is the low-priority report 4912211 "add mechanism to restore hijacked .jar and .jnlp file extensions", but it has been closed as "Closed, Will Not Fix".

You may also miss the file connection with .jar if you are using a free OpenJDK without an installer.

Notice: my OS is Windows 10, but logic is the same for 7, 8 and so on.

CONCAT, as stated, is not supported prior to SQL Server 2012. However you can concatenate simply using the + operator as suggested. But beware, this operator will throw an error if the first operand is a number since it thinks will be adding and not concatenating. To resolve this issue just add '' in front. For example

someNumber + 'someString' + .... + lastVariableToConcatenate

will raise an error BUT '' + someNumber + 'someString' + ...... will work just fine.

Also, if there are two numbers to be concatenated make sure you add a '' between them, like so

.... + someNumber + '' + someOtherNumber + .....

I'm not content with HTML/CSS-only solutions, so I've decided to create a custom select using JavaScript.

This is something I've written in the past 30 mins, thus it can be further improved.

All you have to do is create a simple list with few data attributes. The code automatically turns the list into a selectable dropdown. It also adds a hidden input to hold the selected value, so it can be used in a form.

Input:

<ul class="select" data-placeholder="Role" data-name="role">
  <li data-value="admin">Administrator</li>
  <li data-value="mod">Moderator</li>
  <li data-value="user">User</li>
</ul>

Output:

<div class="ul-select-container">
    <input type="hidden" name="role" class="hidden">
    <div class="selected placeholder">
        <span class="text">Role</span>
        <span class="icon">?</span>
    </div>
    <ul class="select" data-placeholder="Role" data-name="role">
        <li class="placeholder">Role</li>
        <li data-value="admin">Administrator</li>
        <li data-value="mod">Moderator</li>
        <li data-value="user">User</li>
    </ul>
</div>

The text of the item that's supposed to be a placeholder is grayed out. The placeholder is selectable, in case the user wants to revert his/her choice. Also using CSS, all the drawbacks of select can be overcome (e.g., inability of the styling of the options).

Update: I am have rewritten this again. Instead of using a list, we can just use a select. This way it'll work even without JavaScript (in case it's disabled).

Input:

<select name="role" data-placeholder="Role" required title="Role">
    <option value="admin">Administrator</option>
    <option value="mod">Moderator</option>

Run xampp services by command line

To start apache service

sudo /Applications/XAMPP/xamppfiles/bin/apachectl start

To start mysql service

sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

Both commands are working like charm :)

If your working directory points to the trunk, then you should be able to merge your branch with:

svn merge https://HOST/repository/branches/branch_1

be sure to be to issue this command in the root directory of your trunk

If we want to add custom HTTP headers to a POST request, we must pass them through a dictionary to the headers parameter.

Here is an example with a non-empty body and headers:

import requests
import json

url = 'https://somedomain.com'
body = {'name': 'Maryja'}
headers = {'content-type': 'application/json'}

r = requests.post(url, data=json.dumps(body), headers=headers)

Syntax for replacing a specific characters:

REPLACE ( string_expression , string_pattern , string_replacement )  

For example in the string "HelloReplaceThingsGoing" Replace word is replaced by How

SELECT REPLACE('HelloReplaceThingsGoing','Replace','How');
GO

you can use the like query for comparing the respective string with table vales.

select column name from table_name where column name like 'respective comparing value';

Use this:

In [105]: a
Out[105]: 
array([[15, 30, 88, 31, 33],
       [53, 38, 54, 47, 56],
       [67,  2, 74, 10, 16],
       [86, 33, 15, 51, 32],
       [32, 47, 76, 15, 81]], dtype=int32)

In [106]: float32(a)
Out[106]: 
array([[ 15.,  30.,  88.,  31.,  33.],
       [ 53.,  38.,  54.,  47.,  56.],
       [ 67.,   2.,  74.,  10.,  16.],
       [ 86.,  33.,  15.,  51.,  32.],
       [ 32.,  47.,  76.,  15.,  81.]], dtype=float32)

I found applying the network and rebooting both the nodes did the trick for me.

kubectl apply -f [podnetwork].yaml

SELECT id, GROUP_CONCAT(name SEPARATOR ' ') FROM table GROUP BY id;

https://dev.mysql.com/doc/refman/8.0/en/aggregate-functions.html#function_group-concat

From the link above, GROUP_CONCAT: This function returns a string result with the concatenated non-NULL values from a group. It returns NULL if there are no non-NULL values.

Solution
Change the setup for your application, so you this parameter[-Djava.security.egd=file:/dev/../dev/urandom] next to the java command:

java -Djava.security.egd=file:/dev/../dev/urandom [your command]

Use FormData object.It works for any type of form

$(document).on("submit", "form", function(event)
{
    event.preventDefault();
    $.ajax({
        url: $(this).attr("action"),
        type: $(this).attr("method"),
        dataType: "JSON",
        data: new FormData(this),
        processData: false,
        contentType: false,
        success: function (data, status)
        {

        },
        error: function (xhr, desc, err)
        {
            

        }
    });        

});

To get all column name you can iterate over the data_all2.columns.

columns = data_all2.columns
for col in columns:
    print col

You will get all column names. Or you can store all column names to another list variable and then print list.

int value, *ptr;

value = 8;
ptr = &value;
// ptr points to value, which lives on a stack frame.
// you are not responsible for managing its lifetime.

ptr = new int;
delete ptr;
// yes this is the normal way to manage the lifetime of
// dynamically allocated memory, you new'ed it, you delete it.

ptr = nullptr;
delete ptr;
// this is illogical, essentially you are saying delete nothing.

You can use the MailDefinition class.

This is how you use it:

MailDefinition md = new MailDefinition();
md.From = "[email protected]";
md.IsBodyHtml = true;
md.Subject = "Test of MailDefinition";

ListDictionary replacements = new ListDictionary();
replacements.Add("{name}", "Martin");
replacements.Add("{country}", "Denmark");

string body = "<div>Hello {name} You're from {country}.</div>";

MailMessage msg = md.CreateMailMessage("[email protected]", replacements, body, new System.Web.UI.Control());

Also, I've written a blog post on how to generate HTML e-mail body in C# using templates using the MailDefinition class.

1. brew install python3

2. create alias in your shell profile

   • eg. alias pip3="python3 -m pip" in my .zshrc

? ~ pip3 --version

pip 9.0.1 from /usr/local/lib/python3.6/site-packages (python 3.6)

<description><![CDATA[first line<br/>second line<br/>]]></description>

You can use one of the following.

• $! is the PID of the last backgrounded process.
• kill -0 $PID checks whether it's still running.
• $$ is the PID of the current shell.

For windows, @shoaly parameters didn't completely work for me. I was getting this error:

NCAT DEBUG: Proxy returned status code 501.
Ncat: Proxy returned status code 501.
ssh_exchange_identification: Connection closed by remote host

I wanted to ssh to a REMOTESERVER and the SSH port had been closed in my network. I found two solutions but the second is better.

• To solve the problem using Ncat:

  1. I downloaded Tor Browser, run and wait to connect.
  2. I got Ncat from Nmap distribution and extracted ncat.exe into the current directory.

  3. SSH using Ncat as ProxyCommand in Git Bash with addition --proxy-type socks4 parameter:

     ssh -o "ProxyCommand=./ncat --proxy-type socks4 --proxy 127.0.0.1:9150 %h %p" USERNAME@REMOTESERVER
     

     Note that this implementation of Ncat does not support socks5.

• THE BETTER SOLUTION:

  1. Do the previous step 1.

  2. SSH using connect.c as ProxyCommand in Git Bash:

     ssh -o "ProxyCommand=connect -a none -S 127.0.0.1:9150 %h %p"
     

     Note that connect.c supports socks version 4/4a/5.

To use the proxy in git commands using ssh (for example while using GitHub) -- assuming you installed Git Bash in C:\Program Files\Git\ -- open ~/.ssh/config and add this entry:

host github.com
    user git
    hostname github.com
    port 22
    proxycommand "/c/Program Files/Git/mingw64/bin/connect.exe" -a none -S 127.0.0.1:9150 %h %p

if you used vue-cli and webpack when you created your project.

you can use just

npm run build command in command line, and it will create dist folder in your project. Just upload content of this folder to your ftp and done.

here is my solution. base on spring-boot.1.2.5.RELEASE.

    public DataSource firstDataSource() {
        DataSource ds =  DataSourceBuilder.create().build();
        return ds;
    }

    @Bean
    @ConfigurationProperties(prefix="second.datasource")
    public DataSource secondDataSource() {

        return ds;
    }
}

Your formula should be of the form =IF(X2 >= 85,0.559,IF(X2 >= 80,0.327,IF(X2 >=75,0.255,0))). This simulates the ELSE-IF operand Excel lacks. Your formulas were using two conditions in each, but the second parameter of the IF formula is the value to use if the condition evaluates to true. You can't chain conditions in that manner.

([io.fileinfo]"c:\temp\myfile.txt").basename

or

The installation of CuDNN is just copying some files. Hence to check if CuDNN is installed (and which version you have), you only need to check those files.

Install CuDNN

Step 1: Register an nvidia developer account and download cudnn here (about 80 MB). You might need nvcc --version to get your cuda version.

Step 2: Check where your cuda installation is. For most people, it will be /usr/local/cuda/. You can check it with which nvcc.

Step 3: Copy the files:

$ cd folder/extracted/contents
$ sudo cp include/cudnn.h /usr/local/cuda/include
$ sudo cp lib64/libcudnn* /usr/local/cuda/lib64
$ sudo chmod a+r /usr/local/cuda/lib64/libcudnn*

Check version

You might have to adjust the path. See step 2 of the installation.

$ cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2

Notes

When you get an error like

F tensorflow/stream_executor/cuda/cuda_dnn.cc:427] could not set cudnn filter descriptor: CUDNN_STATUS_BAD_PARAM

with TensorFlow, you might consider using CuDNN v4 instead of v5.

Ubuntu users who installed it via apt: https://askubuntu.com/a/767270/10425

Go to Webapp folder of you Apache tomcat you will see a folder name matching with your war file name.

Type link in your url address bar:: localhost:8080/HelloWorld/HelloWorld.html and press enter

Time to contribute now. I am sysadmin role and worked on getting two public access users to execute xp_cmdshell. I am able to execute xp_cmdshell but not the two users.

I did the following steps:

1. create new role:

   use master
   CREATE ROLE [CmdShell_Executor] AUTHORIZATION [dbo]
   GRANT EXEC ON xp_cmdshell TO [CmdShell_Executor]

2. add users in master database: Security --> Users. Membership checks only [CmdShell_Executor] that is just created

3. set up proxy account:

   EXEC sp_xp_cmdshell_proxy_account 'domain\user1','users1 Windows password'
   EXEC sp_xp_cmdshell_proxy_account 'domain\user2','users2 Windows password'

Then both users can execute the stored procedure that contains xp_cmdshell invoking a R script run. I let the users come to my PC to type in the password, execute the one line code, then delete the password.

You call nextElement() twice in your loop. This call moves the enumeration pointer forward. You should modify your code like the following:

while (e.hasMoreElements()) {
    String param = e.nextElement();
    System.out.println(param);
}

This should work:

data.groupby(lambda x: data['date'][x].year)

Method with boolean argument :

  request.getSession(true);

returns new session, if the session is not associated with the request

  request.getSession(false);

returns null, if the session is not associated with the request.

Method without boolean argument :

  request.getSession();

returns new session, if the session is not associated with the request and returns the existing session, if the session is associated with the request.It won't return null.

There is a rather clever solution:

#define MACRO(X,Y)                         \
do {                                       \
  cout << "1st arg is:" << (X) << endl;    \
  cout << "2nd arg is:" << (Y) << endl;    \
  cout << "Sum is:" << ((X)+(Y)) << endl;  \
} while (0)

Now you have a single block-level statement, which must be followed by a semicolon. This behaves as expected and desired in all three examples.

.click events only work when element gets rendered and are only attached to elements loaded when the DOM is ready.

.on events are dynamically attached to DOM elements, which is helpful when you want to attach an event to DOM elements that are rendered on ajax request or something else (after the DOM is ready).

$('#cloneDiv').click(function(){_x000D_
_x000D_
_x000D_
  // get the last DIV which ID starts with ^= "klon"_x000D_
  var $div = $('div[id^="klon"]:last');_x000D_
_x000D_
  // Read the Number from that DIV's ID (i.e: 3 from "klon3")_x000D_
  // And increment that number by 1_x000D_
  var num = parseInt( $div.prop("id").match(/\d+/g), 10 ) +1;_x000D_
_x000D_
  // Clone it and assign the new ID (i.e: from num 4 to ID "klon4")_x000D_
  var $klon = $div.clone().prop('id', 'klon'+num );_x000D_
_x000D_
  // Finally insert $klon wherever you want_x000D_
  $div.after( $klon.text('klon'+num) );_x000D_
_x000D_
});

<script src="https://code.jquery.com/jquery-3.1.0.js"></script>_x000D_
_x000D_
<button id="cloneDiv">CLICK TO CLONE</button> _x000D_
_x000D_
<div id="klon1">klon1</div>_x000D_
<div id="klon2">klon2</div>

Scrambled elements, retrieve highest ID

Say you have many elements with IDs like klon--5 but scrambled (not in order). Here we cannot go for :last or :first, therefore we need a mechanism to retrieve the highest ID:

const $all = $('[id^="klon--"]');_x000D_
const maxID = Math.max.apply(Math, $all.map((i, el) => +el.id.match(/\d+$/g)[0]).get());_x000D_
const nextId = maxID + 1;_x000D_
_x000D_
console.log(`New ID is: ${nextId}`);

<div id="klon--12">12</div>_x000D_
<div id="klon--34">34</div>_x000D_
<div id="klon--8">8</div>_x000D_
_x000D_
<script src="https://code.jquery.com/jquery-3.1.0.js"></script>

You can try this logic because it is worked for me.

frag_profile profile_fragment = new frag_profile();

boolean flag = false;
@SuppressLint("ResourceType")
public void profile_Frag(){
    if (flag == false) {
        FragmentManager manager = getFragmentManager();
        FragmentTransaction transaction = manager.beginTransaction();
        manager.getBackStackEntryCount();
        transaction.setCustomAnimations(R.anim.transition_anim0, R.anim.transition_anim1);
        transaction.replace(R.id.parentPanel, profile_fragment, "FirstFragment");
        transaction.commit();
        flag = true;
    }

}

@Override
public void onBackPressed() {
    if (flag == true) {
        FragmentManager manager = getFragmentManager();
        FragmentTransaction transaction = manager.beginTransaction();
        manager.getBackStackEntryCount();
        transaction.remove(profile_fragment);
        transaction.commit();
        flag = false;
    }
    else super.onBackPressed();
}

The documentation explains it pretty well:

An instance of HashMap has two parameters that affect its performance: initial capacity and load factor. The capacity is the number of buckets in the hash table, and the initial capacity is simply the capacity at the time the hash table is created. The load factor is a measure of how full the hash table is allowed to get before its capacity is automatically increased. When the number of entries in the hash table exceeds the product of the load factor and the current capacity, the hash table is rehashed (that is, internal data structures are rebuilt) so that the hash table has approximately twice the number of buckets.

As a general rule, the default load factor (.75) offers a good tradeoff between time and space costs. Higher values decrease the space overhead but increase the lookup cost (reflected in most of the operations of the HashMap class, including get and put). The expected number of entries in the map and its load factor should be taken into account when setting its initial capacity, so as to minimize the number of rehash operations. If the initial capacity is greater than the maximum number of entries divided by the load factor, no rehash operations will ever occur.

As with all performance optimizations, it is a good idea to avoid optimizing things prematurely (i.e. without hard data on where the bottlenecks are).

What you are trying to do is add additional information to each item in the list that you already created so

    alist[ 'from form', 'stuff 2', 'stuff 3']

    for j in range( 0,len[alist]):
        temp= []
        temp.append(alist[j]) # alist[0] is 'from form' 
        temp.append('t') # slot for first piece of data 't'
        temp.append('-') # slot for second piece of data

    blist.append(temp)      # will be alist with 2 additional fields for extra stuff assocated with each item in alist  

For the record, Dart 2.3 added the ability to use if/else statements in Collection literals. This is now done the following way:

return Column(children: <Widget>[
  Text("hello"),
  if (condition)
     Text("should not render if false"),
  Text("world")
],);

Flutter Issue #28181 - Inline conditional rendering in list

You have to use RegExp object if your pattern is string

var xxx = "victoria";
var yyy = "i";
var rgxp = new RegExp(yyy, "g");
alert(xxx.match(rgxp).length);

If pattern is not dynamic string:

var xxx = "victoria";
var yyy = /i/g;
alert(xxx.match(yyy).length);

I try to make it simple. You have two options while using Selenium 3+:

• Either upgrade your Firefox to 47.0.1 or higher and use the default geckodriver of Selenium3.

• Or disable using of geckodriver by specifying marionette to false and use the legacy Firefox driver. a simple command to run selenium is: java -Dwebdriver.firefox.marionette=false -jar selenium-server-standalone-3.0.1.jar. You can also disable using geckodriver from other commands that are mentioned in other answers.

You can do the same like this:

@Override
public FaqQuestions getFaqQuestionById(Long questionId) {
    session = sessionFactory.openSession();
    tx = session.beginTransaction();
    FaqQuestions faqQuestions = null;
    try {
        faqQuestions = (FaqQuestions) session.get(FaqQuestions.class,
                questionId);
        Hibernate.initialize(faqQuestions.getFaqAnswers());

        tx.commit();
        faqQuestions.getFaqAnswers().size();
    } finally {
        session.close();
    }
    return faqQuestions;
}

Just use faqQuestions.getFaqAnswers().size()nin your controller and you will get the size if lazily intialised list, without fetching the list itself.

If you are using cygwin for git and trying to clone a git repository from a network drive you need to add the cygdrive path.

For example if you are cloning a git repo from z:/

$ git clone /cygdrive/z/[repo].git

Here's a one-liner using Maven:

mvn dependency:get -Dartifact=mysql:mysql-connector-java:5.1.38

Then, with default settings, it's available in:

$HOME/.m2/repository/mysql/mysql-connector-java/5.1.38/mysql-connector-java-5.1.38.jar

Just replace the version number if you need a different one.

useEffect has its own state/lifecycle, it will not update until you pass a function in parameters or effect destroyed.

object and array spread or rest will not work inside useEffect.

React.useEffect(() => {
    console.log("effect");

        try {
            let result = await fetch("/query/countries");
            const res = await result.json();

above suggestions didnt work for me. but the below one does.

Want to change the text inside the anchor dynamically. The word "Search". Created an inner tag "font" with an id attribute. Managed the contents using javascript (below)

Search

script contents:

    var searchText = "Search";
    var editSearchText = "Edit Search";
    var currentSearchText = searchText;

    function doSearch() {
        if (currentSearchText == searchText) {
            $('#pSearch').panel('close');
            currentSearchText = editSearchText;
        } else if (currentSearchText == editSearchText) {
            $('#pSearch').panel('open');
            currentSearchText = searchText;
        }
        $('#searchtxt').text(currentSearchText);
    }

$product=Mage::getModel('catalog/product')->load($product_id);

above code not working for me. its throw exception;

This is working for me for get product details.

$obj = Mage::getModel('catalog/product'); $_product = $obj->load($product_id);

So use for for product type.

$productType = $_product->getTypeId();

The second way is a tad more efficient, but a much better way is to execute them in batches:

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL);
    ) {
        for (Entity entity : entities) {
            statement.setObject(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
        }

        statement.executeBatch();
    }
}

You're however dependent on the JDBC driver implementation how many batches you could execute at once. You may for example want to execute them every 1000 batches:

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL);
    ) {
        int i = 0;

        for (Entity entity : entities) {
            statement.setObject(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
            i++;

            if (i % 1000 == 0 || i == entities.size()) {
                statement.executeBatch(); // Execute every 1000 items.
            }
        }
    }
}

As to the multithreaded environments, you don't need to worry about this if you acquire and close the connection and the statement in the shortest possible scope inside the same method block according the normal JDBC idiom using try-with-resources statement as shown in above snippets.

If those batches are transactional, then you'd like to turn off autocommit of the connection and only commit the transaction when all batches are finished. Otherwise it may result in a dirty database when the first bunch of batches succeeded and the later not.

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (Connection connection = dataSource.getConnection()) {
        connection.setAutoCommit(false);

        try (PreparedStatement statement = connection.prepareStatement(SQL)) {
            // ...

            try {
                connection.commit();
            } catch (SQLException e) {
                connection.rollback();
                throw e;
            }
        }
    }
}

I just wanted to echo @Luann's comment as I use this approach always.

Just right click on the table > Script table as > Select to > New Query window.

You will see the select query. Just take out the column you want to exclude and you have your preferred select query.

I second Harmen's div suggestion. Alternatively, you can wrap the table in a form, and use javascript to capture the row focus and adjust the form action via javascript before submit.

You can use CSS3 transitions with rotate() to spin the image on hover.

Rotating image :

img {_x000D_
  border-radius: 50%;_x000D_
  -webkit-transition: -webkit-transform .8s ease-in-out;_x000D_
          transition:         transform .8s ease-in-out;_x000D_
}_x000D_
img:hover {_x000D_
  -webkit-transform: rotate(360deg);_x000D_
          transform: rotate(360deg);_x000D_
}

<img src="https://i.stack.imgur.com/BLkKe.jpg" width="100" height="100"/>

Here is a fiddle DEMO

You're setting the global git options, but the local checkout possibly has overrides set. Try setting them again with git config --local <setting> <value>. You can look at the .git/config file in your local checkout to see what local settings the checkout has defined.

=if([Logical Test 1],[Action 1],if([Logical Test 2],[Action 1],if([Logical Test 3],[Action 3],[Value if all logical tests return false])))

Replace the components in the square brackets as necessary.

Really surprised this hasn't been posted before.

strcpy(&str[idx_to_delete], &str[idx_to_delete + 1]);

Pretty efficient and simple. strcpy uses memmove on most implementations.

Martin Porter wrote Snowball (a language for stemming algorithms) and rewrote the "English Stemmer" in Snowball. There are is an English Stemmer for C and Java.

He explicitly states that the Porter Stemmer has been reimplemented only for historical reasons, so testing stemming correctness against the Porter Stemmer will get you results that you (should) already know.

From http://tartarus.org/~martin/PorterStemmer/index.html (emphasis mine)

The Porter stemmer should be regarded as ‘frozen’, that is, strictly defined, and not amenable to further modification. As a stemmer, it is slightly inferior to the Snowball English or Porter2 stemmer, which derives from it, and which is subjected to occasional improvements. For practical work, therefore, the new Snowball stemmer is recommended. The Porter stemmer is appropriate to IR research work involving stemming where the experiments need to be exactly repeatable.

Dr. Porter suggests to use the English or Porter2 stemmers instead of the Porter stemmer. The English stemmer is what's actually used in the demo site as @StompChicken has answered earlier.

If you convert table field:

1. Define the field so it contains seconds:

    CREATE TABLE IF NOT EXISTS test (
        ...
        field        INTERVAL SECOND(0)
    );
   

2. Extract the value. Remember to cast to int other wise you can get an unpleasant surprise once the intervals are big:

   EXTRACT(EPOCH FROM field)::int

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)

Here's something which might be useful. Selecting the entire column based on a row containing data, in this case i am using 5th row:

Dim lColumn As Long

lColumn = ActiveSheet.Cells(5, Columns.Count).End(xlToLeft).Column
MsgBox ("The last used column is: " & lColumn)

You could make it through iframes... I made something, but my only problem for now is syncing those divs to scroll simultaneous... its terrible way, because its like you load 2 websites, but the only way I found... you could also work with divs and overflow I guess...

I tried all the other suggestions in the answers here, none of which worked. Eventually I used Process Monitor to discover that my .exe that VS2010 was failing to build was locked by the System process (PID=4). Searching SO for situations involving this yielded this answer.

Summarised: if you have the Application Experience service disabled (as I did) then re-enable and start it. Two years of aggravation ended.

The idiom is to use the bitwise or-equal operator to set bits:

flags |= 0x04;

To clear a bit, the idiom is to use bitwise and with negation:

flags &= ~0x04;

Sometimes you have an offset that identifies your bit, and then the idiom is to use these combined with left-shift:

flags |= 1 << offset;
flags &= ~(1 << offset);

If you want to refresh the entire page, it makes no sense to use AJAX. Use normal Javascript to post the form element in that page. Make sure the form submits to the same page, or that the form submits to a page which then redirects back to that page

Javascript to be used (always in myForm.php):

function submitform()
{
  document.getElementById('myForm').submit();
}

Suppose your form is on myForm.php: Method 1:

<form action="./myForm.php" method="post" id="myForm">
    ...
</form>

Method 2:

myForm.php:

<form action="./myFormActor.php" method="post" id="myForm">
    ...
</form>

myFormActor.php:

<?php
    //all code here, no output
    header("Location: ./myForm.php");
?>

You may try the Open Source Active Python Setup which is a well done Python installer for Windows. You just have to desinstall your version and install it...

Running:

npm install

from inside your app directory (i.e. where package.json is located) will install the dependencies for your app, rather than install it as a module, as described here. These will be placed in ./node_modules relative to your package.json file (it's actually slightly more complex than this, so check the npm docs here).

You are free to move the node_modules dir to the parent dir of your app if you want, because node's 'require' mechanism understands this. However, if you want to update your app's dependencies with install/update, npm will not see the relocated 'node_modules' and will instead create a new dir, again relative to package.json.

To prevent this, just create a symlink to the relocated node_modules from your app dir:

ln -s ../node_modules node_modules

Hopes this makes it find the tables as you're reading through the thing:

        printf("%s%s\n",BLUE, dir->d_name);

        char d_path[255]; // here I am using sprintf which is safer than strcat
        sprintf(d_path, "%s/%s", path, dir->d_name);
        show_dir_content(d_path); // recall with the new path
      }
    }
    closedir(d); // finally close the directory
}

int main(int argc, char **argv)
{

  printf("%s\n", NORMAL_COLOR);

    show_dir_content(argv[1]);

  printf("%s\n", NORMAL_COLOR);
  return(0);
}

Disclaimer: I'm a developer of Cytoscape.js

Cytoscape.js is a HTML5 graph visualisation library. The API is sophisticated and follows jQuery conventions, including

• selectors for querying and filtering (cy.elements("node[weight >= 50].someClass") does much as you would expect),
• chaining (e.g. cy.nodes().unselect().trigger("mycustomevent")),
• jQuery-like functions for binding to events,
• elements as collections (like jQuery has collections of HTMLDomElements),
• extensibility (can add custom layouts, UI, core & collection functions, and so on),
• and more.

If you're thinking about building a serious webapp with graphs, you should at least consider Cytoscape.js. It's free and open-source:

http://js.cytoscape.org

you can use regex in order to catch any length of white space, and this would be like:

var text = "hoi how     are          you";
var arr = text.split(/\s+/);

console.log(arr) // will result : ["hoi", "how", "are", "you"]

console.log(arr[2]) // will result : "are" 

One benefit is elimination a lot of nested if let statements. See the WWDC "What's New in Swift" video around 15:30, the section titled "Pyramid of Doom".

It seems that CharEscapers from Google GData-java-client has what you want. It has uriPathEscaper method, uriQueryStringEscaper, and generic uriEscaper. (All return Escaper object which does actual escaping). Apache License.

My situation and solution: I had created and enabled a HyperV ethernet adapter. For some reason, my main windows machine was using the "virtual" ethernet adapter instead of the 'hardware' adapter.

I disabled the virtual ethernet and my network settings to change the network public/privacy settings were revealed.

Assuming you want all "overlapping" time periods, i.e. all that have at least one day in common.

Try to envision time periods on a straight time line and move them around before your eyes and you will see the necessary conditions.

SELECT *
FROM   tbl
WHERE  start_date <= '2012-04-12'::date
AND    end_date   >= '2012-01-01'::date;

This is sometimes faster for me than OVERLAPS - which is the other good way to do it (as @Marco already provided).

Note the subtle difference (per documentation):

OVERLAPS automatically takes the earlier value of the pair as the start. Each time period is considered to represent the half-open interval start <= time < end, unless start and end are equal in which case it represents that single time instant. This means for instance that two time periods with only an endpoint in common do not overlap.

Bold emphasis mine.

Performance

For big tables the right index can help performance (a lot).

CREATE INDEX tbl_date_inverse_idx ON tbl(start_date, end_date DESC);

Possibly with another (leading) index column if you have additional selective conditions.

Note the inverse order of the two columns. Detailed explanation:

• Optimizing queries on a range of timestamps (two columns)

Try using this this.getClass().getCanonicalName() or this.getClass().getSimpleName(). If it's an anonymous class, use this.getClass().getSuperclass().getName()

Search extension in

/etc/php5/apache2/php.ini

The below code works for all the screens :

.jumbotron {
   background: url('backgroundimage.jpg') no-repeat center center fixed;
   -webkit-background-size: cover;
   -moz-background-size: cover;
   background-size: cover;
   -o-background-size: cover;
}

The cover property will resize the background image to cover the entire container, even if it has to stretch the image or cut a little bit off one of the edges.

Here is a list of what can be pickled. In particular, functions are only picklable if they are defined at the top-level of a module.

This piece of code:

import multiprocessing as mp

class Foo():
    @staticmethod
    def work(self):
        pass

if __name__ == '__main__':   
    pool = mp.Pool()
    foo = Foo()
    pool.apply_async(foo.work)
    pool.close()
    pool.join()

yields an error almost identical to the one you posted:

Exception in thread Thread-2:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 552, in __bootstrap_inner
    self.run()
  File "/usr/lib/python2.7/threading.py", line 505, in run
    self.__target(*self.__args, **self.__kwargs)
  File "/usr/lib/python2.7/multiprocessing/pool.py", line 315, in _handle_tasks
    put(task)
PicklingError: Can't pickle <type 'function'>: attribute lookup __builtin__.function failed

The problem is that the pool methods all use a mp.SimpleQueue to pass tasks to the worker processes. Everything that goes through the mp.SimpleQueue must be pickable, and foo.work is not picklable since it is not defined at the top level of the module.

It can be fixed by defining a function at the top level, which calls foo.work():

def work(foo):
    foo.work()

pool.apply_async(work,args=(foo,))

Notice that foo is pickable, since Foo is defined at the top level and foo.__dict__ is picklable.

In my case, I was getting this error message because I was changed the service's namespace and services tag was pointed to the older namespace. I refreshed the namespace and the error disapear:

<services>
  <service name="My.Namespace.ServiceName"> <!-- Updated name -->
    <endpoint address="" 
              binding="wsHttpBinding" 
              bindingConfiguration="MyBindingConfiguratioName" 
              contract="My.Namespace.Interface" <!-- Updated contract -->
    />
  </service>
</services>

As an alternative to rendering a raster image, you can embed a SVG file:

<a><img src="http://dump.thecybershadow.net/6c736bfd11ded8cdc5e2bda009a6694a/colortext.svg"/></a>

You can then add color text to the SVG file as usual:

<?xml version="1.0" encoding="utf-8"?>
<svg version="1.1" 
     xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink"
     width="100" height="50"
>
  <text font-size="16" x="10" y="20">
    <tspan fill="red">Hello</tspan>,
    <tspan fill="green">world</tspan>!
  </text>
</svg>

Unfortunately, even though you can select and copy text when you open the .svg file, the text is not selectable when the SVG image is embedded.

Demo: https://gist.github.com/CyberShadow/95621a949b07db295000

You can set the attribute translatable="false" on the definition like this:

<string name="account_setup_imap" translatable="false">IMAP</string>

For more information: http://tools.android.com/recent/non-translatablestrings

When you read() the file, you may get a newline character '\n' in your string. Try either

if UserInput.strip() == 'List contents': 

or

if 'List contents' in UserInput: 

Also note that your second file open could also use with:

with open('/Users/.../USER_INPUT.txt', 'w+') as UserInputFile:     if UserInput.strip() == 'List contents': # or if s in f:         UserInputFile.write("ls")     else:         print "Didn't work" 

It could be easily achieved with CSS flex. Having HTML markup as follows:

<html>
    <body>
        <div class="container"></div>
        <div class="footer"></div>
    </body>
</html>

Following CSS should be used:

html {
    height: 100%;
}
body {
    min-height: 100%;
   display: flex;
   flex-direction: column;
}
body > .container {
    flex-grow: 1;
}

Here's CodePen to play with: https://codepen.io/webdevchars/pen/GPBqWZ

Your comparison function is not even wrong.

Its arguments should be the type stored in the range, i.e. std::pair<K,V>, not const void*.

It should return bool not a positive or negative value. Both (bool)1 and (bool)-1 are true so your function says every object is ordered before every other object, which is clearly impossible.

You need to model the less-than operator, not strcmp or memcmp style comparisons.

See StrictWeakOrdering which describes the properties the function must meet.
