This addresses the different question, how to get images in gist (as opposed to github) markdown in the first place ?

1. Make a gist, say Mygist.md (and optionally more files)
2. Go to the "Write Comment" box at the end
3. Click "Attach files ... by selecting them"; select your local image file
4. GitHub echos a long long string where it put the image, e.g. 
5. Cut-paste that by hand into your Mygist.md.

But: GitHub people may change this behavior tomorrow, without documenting it.

Some color-syntaxing enrichment can be applied with the following blockcode syntax

```json
Here goes your json object definition
```

Note: This won't prettify the json representation. To do so, one can previously rely on an external service such as jsbeautifier.org and paste the prettified result in the wiki.

As an alternate to adding a comma for each item you could just using String.Join:

var strgroupids = String.Join(",",  groupIds);

This will add the seperator ("," in this instance) between each element in the array.

I was looking into this but wanted to have a different transition rate for in and out.

This is what I ended up doing:

//css
.addedClass {
    background: #5eb4fc;
}

// js
function setParentTransition(id, prop, delay, style, callback) {
    $(id).css({'-webkit-transition' : prop + ' ' + delay + ' ' + style});
    $(id).css({'-moz-transition' : prop + ' ' + delay + ' ' + style});
    $(id).css({'-o-transition' : prop + ' ' + delay + ' ' + style});
    $(id).css({'transition' : prop + ' ' + delay + ' ' + style});
    callback();
}
setParentTransition(id, 'background', '0s', 'ease', function() {
    $('#elementID').addClass('addedClass');
});

setTimeout(function() {
    setParentTransition(id, 'background', '2s', 'ease', function() {
        $('#elementID').removeClass('addedClass');
    });
});

This instantly turns the background color to #5eb4fc and then slowly fades back to normal over 2 seconds.

Here's a fiddle

[[UIDevice currentDevice] systemVersion]

These are the necersary imports:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

And this is a method that will allow you to read from a File by passing it the filename as a parameter like this: readFile("yourFile.txt");

String readFile(String fileName) throws IOException {
    BufferedReader br = new BufferedReader(new FileReader(fileName));
    try {
        StringBuilder sb = new StringBuilder();
        String line = br.readLine();

        while (line != null) {
            sb.append(line);
            sb.append("\n");
            line = br.readLine();
        }
        return sb.toString();
    } finally {
        br.close();
    }
}

If you're using Node.js:

> var ObjectId = require('mongodb').ObjectId; 
> var id = req.params.gonderi_id;       
> var o_id = new ObjectId(id);
> db.test.find({_id:o_id})

Edit: corrected to new ObjectId(id), not new ObjectID(id)

If you run jupyter in the background like me:

jupyter notebook &> /dev/null &

Then to exit jupyter completely, instead of Ctl-C, make an alias command:

echo 'alias quitjupyter="kill $(pgrep jupyter)"' >> ~/.bashrc

Restart your terminal. Kill all jupyter instances:

quitjupyter

Note: use double quotes inside of single quotes as shown above. The other way around will evaluate the expression before writing it to your .bashrc (you want to write the command itself not 'kill 1430' or whatever process number may be associated with a current jupyter instance). Of course you can use any alias you wish. I actually use 'qjup':

echo 'alias qjup="kill $(pgrep jupyter)"' >> ~/.bashrc

Restart your terminal. Kill all jupyter instances:

qjup

Please put this code in head section

<link href='http://fonts.googleapis.com/css?family=Lato:400,700' rel='stylesheet' type='text/css'>

and use font-family: 'Lato', sans-serif; in your css. For example:

h1 {
    font-family: 'Lato', sans-serif;
    font-weight: 400;
}

Or you can use manually also

Generate .ttf font from fontSquiral

and can try this option

    @font-face {
        font-family: "Lato";
        src: url('698242188-Lato-Bla.eot');
        src: url('698242188-Lato-Bla.eot?#iefix') format('embedded-opentype'),
        url('698242188-Lato-Bla.svg#Lato Black') format('svg'),
        url('698242188-Lato-Bla.woff') format('woff'),
        url('698242188-Lato-Bla.ttf') format('truetype');
        font-weight: normal;
        font-style: normal;
}

Called like this

body {
  font-family: 'Lato', sans-serif;
}

In my case the debugged code in JBoss was older than the code in the Eclipse project. Rebuilding the .war solved the problem.

Although ObjectMapper is thread safe, I would strongly discourage from declaring it as a static variable, especially in multithreaded application. Not even because it is a bad practice, but because you are running a heavy risk of deadlocking. I am telling it from my own experience. I created an application with 4 identical threads that were getting and processing JSON data from web services. My application was frequently stalling on the following command, according to the thread dump:

Map aPage = mapper.readValue(reader, Map.class);

Beside that, performance was not good. When I replaced static variable with the instance based variable, stalling disappeared and performance quadrupled. I.e. 2.4 millions JSON documents were processed in 40min.56sec., instead of 2.5 hours previously.

C++0x has given us a further, excellent solution:

std::vector<int> keys;

std::transform(
    m_Inputs.begin(),
    m_Inputs.end(),
    std::back_inserter(keys),
    [](const std::map<int,int>::value_type &pair){return pair.first;});

It worked for me for most of the viewcontrollers.

self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false

It wasn't not working for some viewcontrollers like UIPageViewController. On UIPageViewController's pagecontentviewcontroller below code worked for me.

override func viewDidLoad() {
   self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
   self.navigationController?.interactivePopGestureRecognizer?.delegate = self
}
override func viewWillDisappear(_ animated: Bool) {
   self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
   self.navigationController?.interactivePopGestureRecognizer?.delegate = nil
}

On UIGestureRecognizerDelegate,

func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
   if gestureRecognizer == self.navigationController?.interactivePopGestureRecognizer {
      return false
}
      return true
}

Here's my solution:

public static class EnumerationExtensions
{
    public static IEnumerable<T> TakeLast<T>(this IEnumerable<T> input, int count)
    {
        if (count <= 0)
            yield break;

        var inputList = input as IList<T>;

        if (inputList != null)
        {
            int last = inputList.Count;
            int first = last - count;

            if (first < 0)
                first = 0;

            for (int i = first; i < last; i++)
                yield return inputList[i];
        }
        else
        {
            // Use a ring buffer. We have to enumerate the input, and we don't know in advance how many elements it will contain.
            T[] buffer = new T[count];

            int index = 0;

            count = 0;

            foreach (T item in input)
            {
                buffer[index] = item;

                index = (index + 1) % buffer.Length;
                count++;
            }

            // The index variable now points at the next buffer entry that would be filled. If the buffer isn't completely
            // full, then there are 'count' elements preceding index. If the buffer *is* full, then index is pointing at
            // the oldest entry, which is the first one to return.
            //
            // If the buffer isn't full, which means that the enumeration has fewer than 'count' elements, we'll fix up
            // 'index' to point at the first entry to return. That's easy to do; if the buffer isn't full, then the oldest
            // entry is the first one. :-)
            //
            // We'll also set 'count' to the number of elements to be returned. It only needs adjustment if we've wrapped
            // past the end of the buffer and have enumerated more than the original count value.

            if (count < buffer.Length)
                index = 0;
            else
                count = buffer.Length;

            // Return the values in the correct order.
            while (count > 0)
            {
                yield return buffer[index];

                index = (index + 1) % buffer.Length;
                count--;
            }
        }
    }

    public static IEnumerable<T> SkipLast<T>(this IEnumerable<T> input, int count)
    {
        if (count <= 0)
            return input;
        else
            return input.SkipLastIter(count);
    }

    private static IEnumerable<T> SkipLastIter<T>(this IEnumerable<T> input, int count)
    {
        var inputList = input as IList<T>;

        if (inputList != null)
        {
            int first = 0;
            int last = inputList.Count - count;

            if (last < 0)
                last = 0;

            for (int i = first; i < last; i++)
                yield return inputList[i];
        }
        else
        {
            // Aim to leave 'count' items in the queue. If the input has fewer than 'count'
            // items, then the queue won't ever fill and we return nothing.

            Queue<T> elements = new Queue<T>();

            foreach (T item in input)
            {
                elements.Enqueue(item);

                if (elements.Count > count)
                    yield return elements.Dequeue();
            }
        }
    }
}

The code is a bit chunky, but as a drop-in reusable component, it should perform as well as it can in most scenarios, and it'll keep the code that's using it nice and concise. :-)

My TakeLast for non-IList`1 is based on the same ring buffer algorithm as that in the answers by @Mark Byers and @MackieChan further up. It's interesting how similar they are -- I wrote mine completely independently. Guess there's really just one way to do a ring buffer properly. :-)

Looking at @kbrimington's answer, an additional check could be added to this for IQuerable<T> to fall back to the approach that works well with Entity Framework -- assuming that what I have at this point does not.

I finally figured out a how to use Maven. From within Eclipse, create a new Maven project.

Download Maven, extract the archive, add the /bin folder to path.

Validate install from command-line by running mvn -v (will print version and java install path)

Change to the project root folder (where pom.xml is located) and run:

mvn dependency:copy-dependencies

All jar-files are downloaded to /target/dependency.

To set another output directory:

mvn dependency:copy-dependencies -DoutputDirectory="c:\temp"

Now it's possible to re-use this Maven-project for all dependency downloads by altering the pom.xml

Add jars to java project by build path -> configure build path -> libraries -> add JARs..

Two ways come to mind:

• Using a command-line tool like the popular ffmpeg, however you will almost always need an own server (or a very nice server administrator / hosting company) to get that

• Using the "screenshoot" plugin for the LongTail Video player that allows the creation of manual screenshots that are then sent to a server-side script.

Try this

frame$twohouses <- ifelse(frame$data>1, 2, 1)
 frame
   data twohouses
1     0         1
2     1         1

Conversion from signed to unsigned does not necessarily just copy or reinterpret the representation of the signed value. Quoting the C standard (C99 6.3.1.3):

When a value with integer type is converted to another integer type other than _Bool, if the value can be represented by the new type, it is unchanged.

Otherwise, if the new type is unsigned, the value is converted by repeatedly adding or subtracting one more than the maximum value that can be represented in the new type until the value is in the range of the new type.

Otherwise, the new type is signed and the value cannot be represented in it; either the result is implementation-defined or an implementation-defined signal is raised.

For the two's complement representation that's nearly universal these days, the rules do correspond to reinterpreting the bits. But for other representations (sign-and-magnitude or ones' complement), the C implementation must still arrange for the same result, which means that the conversion can't just copy the bits. For example, (unsigned)-1 == UINT_MAX, regardless of the representation.

In general, conversions in C are defined to operate on values, not on representations.

To answer the original question:

unsigned int u = 1234;
int i = -5678;

unsigned int result = u + i;

The value of i is converted to unsigned int, yielding UINT_MAX + 1 - 5678. This value is then added to the unsigned value 1234, yielding UINT_MAX + 1 - 4444.

(Unlike unsigned overflow, signed overflow invokes undefined behavior. Wraparound is common, but is not guaranteed by the C standard -- and compiler optimizations can wreak havoc on code that makes unwarranted assumptions.)

With the perspective of the OS X v10.7 and iOS 5 launches, probably the first thing to recommend now is NSJSONSerialization, Apple's supplied JSON parser. Use third-party options only as a fallback if you find that class unavailable at runtime.

So, for example:

NSData *returnedData = ...JSON data, probably from a web request...

// probably check here that returnedData isn't nil; attempting
// NSJSONSerialization with nil data raises an exception, and who
// knows how your third-party library intends to react?

if(NSClassFromString(@"NSJSONSerialization"))
{
    NSError *error = nil;
    id object = [NSJSONSerialization
                      JSONObjectWithData:returnedData
                      options:0
                      error:&error];

    if(error) { /* JSON was malformed, act appropriately here */ }

    // the originating poster wants to deal with dictionaries;
    // assuming you do too then something like this is the first
    // validation step:
    if([object isKindOfClass:[NSDictionary class]])
    {
        NSDictionary *results = object;
        /* proceed with results as you like; the assignment to
        an explicit NSDictionary * is artificial step to get 
        compile-time checking from here on down (and better autocompletion
        when editing). You could have just made object an NSDictionary *
        in the first place but stylistically you might prefer to keep
        the question of type open until it's confirmed */
    }
    else
    {
        /* there's no guarantee that the outermost object in a JSON
        packet will be a dictionary; if we get here then it wasn't,
        so 'object' shouldn't be treated as an NSDictionary; probably
        you need to report a suitable error condition */
    }
}
else
{
    // the user is using iOS 4; we'll need to use a third-party solution.
    // If you don't intend to support iOS 4 then get rid of this entire
    // conditional and just jump straight to
    // NSError *error = nil;
    // [NSJSONSerialization JSONObjectWithData:...
}

We can use RegularExpressionValidator to validate email address format. You need to specify the regular expression in ValidationExpression property of RegularExpressionValidator. So it will look like

 <asp:RegularExpressionValidator ID="validateEmail"    
  runat="server" ErrorMessage="Invalid email."
  ControlToValidate="txtEmail" 
  ValidationExpression="^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$" />

Also in event handler of button or link you need to check !Page.IsValid. Check sample code here : sample code

Also if you don't want to use RegularExpressionValidator you can write simple validate method and in that method usinf RegEx class of System.Text.RegularExpressions namespace.

From what I've found online, this is a bug introduced in JDK 1.7.0_45. It appears to also be present in JDK 1.7.0_60. A bug report on Oracle's website states that, while there was a fix, it was removed before the JDK was released. I do not know why the fix was removed, but it confirms what we've already suspected -- the JDK is still broken.

The bug report claims that the error is benign and should not cause any run-time problems, though one of the comments disagrees with that. In my own experience, I have been able to work without any problems using JDK 1.7.0_60 despite seeing the message.

If this issue is causing serious problems, here are a few things I would suggest:

• Revert back to JDK 1.7.0_25 until a fix is added to the JDK.

• Keep an eye on the bug report so that you are aware of any work being done on this issue. Maybe even add your own comment so Oracle is aware of the severity of the issue.

• Try the JDK early releases as they come out. One of them might fix your problem.

Instructions for installing the JDK on Mac OS X are available at JDK 7 Installation for Mac OS X. It also contains instructions for removing the JDK.

olliej's rounding method is wrong for negative numbers

• 2.4 rounded is 2 (olliej's method gets this right)
• -2.4 rounded is -2 (olliej's method returns -1)

Here's an alternative

  int myInt = (int)(myDouble + (myDouble>0 ? 0.5 : -0.5))

You could of course use a rounding function from math.h

You'll need to keep the current value of the input in state (or pass changes in its value up to a parent via a callback function, or sideways, or <your app's state management solution here> such that it eventually gets passed back into your component as a prop) so you can derive the disabled prop for the button.

Example using state:

<meta charset="UTF-8">_x000D_
<script src="https://fb.me/react-0.13.3.js"></script>_x000D_
<script src="https://fb.me/JSXTransformer-0.13.3.js"></script>_x000D_
<div id="app"></div>_x000D_
<script type="text/jsx;harmony=true">void function() { "use strict";_x000D_
_x000D_
var App = React.createClass({_x000D_
  getInitialState() {_x000D_
    return {email: ''}_x000D_
  },_x000D_
  handleChange(e) {_x000D_
    this.setState({email: e.target.value})_x000D_
  },_x000D_
  render() {_x000D_
    return <div>_x000D_
      <input name="email" value={this.state.email} onChange={this.handleChange}/>_x000D_
      <button type="button" disabled={!this.state.email}>Button</button>_x000D_
    </div>_x000D_
  }_x000D_
})_x000D_
_x000D_
React.render(<App/>, document.getElementById('app'))_x000D_
_x000D_
}()</script>

There are two ways

Using split

Then just parse that string

var domain;
//find & remove protocol (http, ftp, etc.) and get domain
if (url.indexOf('://') > -1) {
    domain = url.split('/')[2];
} if (url.indexOf('//') === 0) {
    domain = url.split('/')[2];
} else {
    domain = url.split('/')[0];
}

//find & remove port number
domain = domain.split(':')[0];

To play an Audio file in the Windows form using C# let's check simple example as follows :

1.Go Visual Studio(VS-2008/2010/2012) --> File Menu --> click New Project.

2.In the New Project --> click Windows Forms Application --> Give Name and then click OK.

A new "Windows Forms" project will opens.

3.Drag-and-Drop a Button control from the Toolbox to the Windows Form.

4.Double-click the button to create automatically the default Click event handler, and add the following code.

This code displays the File Open dialog box and passes the results to a method named "playSound" that you will create in the next step.

 OpenFileDialog dialog = new OpenFileDialog();
 dialog.Filter = "Audio Files (.wav)|*.wav";


if(dialog.ShowDialog() == DialogResult.OK)
{
  string path = dialog.FileName;
  playSound(path);
}

5.Add the following method code under the button1_Click event hander.

 private void playSound(string path)
 {
   System.Media.SoundPlayer player = new System.Media.SoundPlayer();
   player.SoundLocation = path;
   player.Load();
   player.Play();
 }

6.Now let's run the application just by Pressing the F5 to run the code.

7.Click the button and select an audio file. After the file loads, the sound will play.

I hope this is useful example to beginners...

Instead of using RequestContextHolder directly, you can also use ServletUriComponentsBuilder and its static methods:

• ServletUriComponentsBuilder.fromCurrentContextPath()
• ServletUriComponentsBuilder.fromCurrentServletMapping()
• ServletUriComponentsBuilder.fromCurrentRequestUri()
• ServletUriComponentsBuilder.fromCurrentRequest()

They use RequestContextHolder under the hood, but provide additional flexibility to build new URLs using the capabilities of UriComponentsBuilder.

Example:

ServletUriComponentsBuilder builder = ServletUriComponentsBuilder.fromCurrentRequestUri();
builder.scheme("https");
builder.replaceQueryParam("someBoolean", false);
URI newUri = builder.build().toUri();

viewNoteDateMonth.text  = [[displayDate objectAtIndex:2] uppercaseString];

Documentation: http://developer.apple.com/library/ios/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html#//apple_ref/occ/instm/NSString/uppercaseString

You can also use lowercaseString and capitalizedString

str.replace(/[[\]]/g,'')

you can use pixels or percent.

There are three ways of accessing the attributes of a DOM Element in JavaScript. All three work reliably in modern browsers as long as you understand how to utilize them.

1. element.attributes

Elements have a property attributes that returns a live NamedNodeMap of Attr objects. The indexes of this collection may be different among browsers. So, the order is not guaranteed. NamedNodeMap has methods for adding and removing attributes (getNamedItem and setNamedItem, respectively).

Notice that though XML is explicitly case sensitive, the DOM spec calls for string names to be normalized, so names passed to getNamedItem are effectively case insensitive.

Example Usage:

var div = document.getElementsByTagName('div')[0];_x000D_
_x000D_
//you can look up specific attributes_x000D_
var classAttr = div.attributes.getNamedItem('CLASS');_x000D_
document.write('attributes.getNamedItem() Name: ' + classAttr.name + ' Value: ' + classAttr.value + '<br>');_x000D_
_x000D_
//you can enumerate all defined attributes_x000D_
for(var i = 0; i < div.attributes.length; i++) {_x000D_
  var attr = div.attributes[i];_x000D_
  document.write('attributes[] Name: ' + attr.name + ' Value: ' + attr.value + '<br>');_x000D_
}_x000D_
_x000D_
//create custom attribute_x000D_
var customAttr = document.createAttribute('customTest');_x000D_
customAttr.value = '567';_x000D_
div.attributes.setNamedItem(customAttr);_x000D_
_x000D_
//retreive custom attribute_x000D_
customAttr = div.attributes.getNamedItem('customTest');_x000D_
document.write('attributes.getNamedItem() Name: ' + customAttr.name + ' Value: ' + customAttr.value + '<br>');

<div class="class1" id="main" data-test="stuff" nonStandard="1234"></div>

2. element.getAttribute & element.setAttribute

These methods exist directly on the Element without needing to access attributes and its methods but perform the same functions.

Again, notice that string name are case insensitive.

Example Usage:

var div = document.getElementsByTagName('div')[0];_x000D_
_x000D_
//get specific attributes_x000D_
document.write('Name: class Value: ' + div.getAttribute('class') + '<br>');_x000D_
document.write('Name: ID Value: ' + div.getAttribute('ID') + '<br>');_x000D_
document.write('Name: DATA-TEST Value: ' + div.getAttribute('DATA-TEST') + '<br>');_x000D_
document.write('Name: nonStandard Value: ' + div.getAttribute('nonStandard') + '<br>');_x000D_
_x000D_
_x000D_
//create custom attribute_x000D_
div.setAttribute('customTest', '567');_x000D_
_x000D_
//retreive custom attribute_x000D_
document.write('Name: customTest Value: ' + div.getAttribute('customTest') + '<br>');

<div class="class1" id="main" data-test="stuff" nonStandard="1234"></div>

3. Properties on the DOM object, such as element.id

Many attributes can be accessed using convenient properties on the DOM object. Which attributes exist depends on the DOM node's type, not which attributes are defined in the HTML. The properties are defined somewhere in the prototype chain of DOM object in question. The specific properties defined will depend on the type of Element you are accessing. For example, className and id are defined on Element and exist on all DOM nodes that are elements (ie. not text or comment nodes). But value is more narrow. It's defined on HTMLInputElement and may not exist on other elements.

Notice that JavaScript properties are case sensitive. Although most properties will use lowercase, some are camelCase. So always check the spec to be sure.

This "chart" captures a portion of the prototype chain for these DOM objects. It's not even close to complete, but it captures the overall structure.

                      ____________Node___________
                      |               |         |
                   Element           Text   Comment
                   |     |
           HTMLElement   SVGElement
           |         |
HTMLInputElement   HTMLSpanElement

Example Usage:

var div = document.getElementsByTagName('div')[0];_x000D_
_x000D_
//get specific attributes_x000D_
document.write('Name: class Value: ' + div.className + '<br>');_x000D_
document.write('Name: id Value: ' + div.id + '<br>');_x000D_
document.write('Name: ID Value: ' + div.ID + '<br>'); //undefined_x000D_
document.write('Name: data-test Value: ' + div.dataset.test + '<br>'); //.dataset is a special case_x000D_
document.write('Name: nonStandard Value: ' + div.nonStandard + '<br>'); //undefined

<div class="class1" id="main" data-test="stuff" nonStandard="1234"></div>

Caveat: This is an explanation of how the HTML spec defines and modern browsers handle attributes. I did not attempt to deal with limitations of ancient, broken browsers. If you need to support old browsers, in addition to this information, you will need to know what is broken in the those browsers.

I believe .clone() is what you're looking for, so long as the class supports it.

Be sure that you do not have a session timeout that is very short, and also make sure that if you are using cookie based sessions that you are accepting the session.

The FireFox webDeveloperToolbar is helpful at times like this as you can see the cookies set for your application.

You can install the package gcolor2 for this:

sudo apt-get install gcolor2

On the realisation that you're unfamiliar with colspan, I presumed you're also unfamiliar with rowspan, so I thought I'd throw that in for free.

One important point to note, when using rowspan: the following tr elements must contain fewer td elements, because of the cells using rowspan in the previous row (or previous rows).

table {_x000D_
  border: 1px solid #000;_x000D_
  border-collapse: collapse;_x000D_
}_x000D_
_x000D_
th,_x000D_
td {_x000D_
  border: 1px solid #000;_x000D_
}

<table>_x000D_
  <thead>_x000D_
    <tr>_x000D_
      <th colspan="2">Column one and two</th>_x000D_
      <th>Column three</th>_x000D_

  </thead>_x000D_
  <tbody>_x000D_
    <tr>_x000D_
      <td rowspan="2" colspan="2">A large cell</td>_x000D_

    <tr>_x000D_
      <!-- note that this row only has _one_ td, since the preceding row_x000D_
                     takes up some of this row -->_x000D_
      <td>Another small cell</td>_x000D_

In order to define a thread formally, we must first understand the boundaries of where a thread operates.

A computer program becomes a process when it is loaded from some store into the computer's memory and begins execution. A process can be executed by a processor or a set of processors. A process description in memory contains vital information such as the program counter which keeps track of the current position in the program (i.e. which instruction is currently being executed), registers, variable stores, file handles, signals, and so forth.

A thread is a sequence of such instructions within a program that can be executed independently of other code. The figure shows the concept:

Threads are within the same process address space, thus, much of the information present in the memory description of the process can be shared across threads.

Some information cannot be replicated, such as the stack (stack pointer to a different memory area per thread), registers and thread-specific data. This information suffices to allow threads to be scheduled independently of the program's main thread and possibly one or more other threads within the program.

Explicit operating system support is required to run multithreaded programs. Fortunately, most modern operating systems support threads such as Linux (via NPTL), BSD variants, Mac OS X, Windows, Solaris, AIX, HP-UX, etc. Operating systems may use different mechanisms to implement multithreading support.

Here, you can find more information about the topic. That was also my information-source.

Let me just add a sentence coming from Introduction to Embedded System by Edward Lee and Seshia:

Threads are imperative programs that run concurrently and share a memory space. They can access each others’ variables. Many practitioners in the field use the term “threads” more narrowly to refer to particular ways of constructing programs that share memory, [others] to broadly refer to any mechanism where imperative programs run concurrently and share memory. In this broad sense, threads exist in the form of interrupts on almost all microprocessors, even without any operating system at all (bare iron).

If you use bootstrap, you might use this -

 <img src="{{URL::asset('/image/propic.png')}}" alt="profile Pic" height="200" width="200">

note: inside public folder create a new folder named image then put your images there. Using URL::asset() you can directly access to the public folder.

Error is coming in your code from this statement as you said

Intent intent = new Intent(context, SendMessage.class);

This is due to you are providing context of OnItemClickListener anonymous class into the Intent constructor but according to constructor of Intent

android.content.Intent.Intent(Context packageContext, Class<?> cls)

You have to provide context of you activity in which you are using intent that is the MainActivity class context. so your statement which is giving error will be converted to

Intent intent = new Intent(MainActivity.this, SendMessage.class);

Also for sending your message from this MainActivity to SendMessage class please see below code

lv.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                ListEntry entry= (ListEntry) parent.getAdapter().getItem(position);
                Intent intent = new Intent(MainActivity.this, SendMessage.class);
                intent.putExtra(EXTRA_MESSAGE, entry.getMessage());
                startActivity(intent);
            }
        });

Please let me know if this helps you

EDIT:- If you are finding some issue to get the value of list do one thing declear your array list

ArrayList<ListEntry> members = new ArrayList<ListEntry>();

globally i.e. before oncreate and change your listener as below

 lv.setOnItemClickListener(new OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position,
                        long id) {
                    Intent intent = new Intent(MainActivity.this, SendMessage.class);
                    intent.putExtra(EXTRA_MESSAGE, members.get(position));
                    startActivity(intent);
                }
            });

So your whole code will look as

public class MainActivity extends Activity {
    public final static String EXTRA_MESSAGE = "com.example.ListViewTest.MESSAGE";
ArrayList<ListEntry> members = new ArrayList<ListEntry>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        members.add(new ListEntry("BBB","AAA",R.drawable.tab1_hdpi));
        members.add(new ListEntry("ccc","ddd",R.drawable.tab2_hdpi));
        members.add(new ListEntry("assa","cxv",R.drawable.tab3_hdpi));
        members.add(new ListEntry("BcxsadvBB","AcxdxvAA"));
        members.add(new ListEntry("BcxvadsBB","AcxzvAA"));
        members.add(new ListEntry("BcxvBB","AcxvAA"));
        members.add(new ListEntry("BvBB","AcxsvAA"));
        members.add(new ListEntry("BcxvBB","AcxsvzAA"));
        members.add(new ListEntry("Bcxadv","AcsxvAA"));
        members.add(new ListEntry("BcxcxB","AcxsvAA"));
        ListView lv = (ListView)findViewById(R.id.listView1);
        Log.i("testTag","before start adapter");
        StringArrayAdapter ad = new StringArrayAdapter (members,this);
        Log.i("testTag","after start adapter");
        Log.i("testTag","set adapter");
        lv.setAdapter(ad);
        lv.setOnItemClickListener(new OnItemClickListener() {
                    @Override
                    public void onItemClick(AdapterView<?> parent, View view, int position,
                            long id) {
                        Intent intent = new Intent(MainActivity.this, SendMessage.class);
                        intent.putExtra(EXTRA_MESSAGE, members.get(position).getMessage());
                        startActivity(intent);
                    }
                });
    }

Where getMessage() will be a getter method specified in your ListEntry class which you are using to get message which was previously set.

You can also try this approach..

public static <E> E[] pickRandom_(int n,E ...item) {
        List<E> copy = Arrays.asList(item);
        Collections.shuffle(copy);
        if (copy.size() > n) {
            return (E[]) copy.subList(0, n).toArray();
        } else {
            return (E[]) copy.toArray();
        }

    }

Keep in mind that the copy constructor limits the class type to that of the copy constructor. Consider the example:

// Need to clone person, which is type Person
Person clone = new Person(person);

This doesn't work if person could be a subclass of Person (or if Person is an interface). This is the whole point of clone, is that it can can clone the proper type dynamically at runtime (assuming clone is properly implemented).

Person clone = (Person)person.clone();

or

Person clone = (Person)SomeCloneUtil.clone(person); // See Bozho's answer

Now person can be any type of Person assuming that clone is properly implemented.

You must place the label after a caption in order to for label to store the table's number, not the chapter's number.

\begin{table}
\begin{tabular}{| p{5cm} | p{5cm} | p{5cm} |}
  -- cut --
\end{tabular}
\caption{My table}
\label{table:kysymys}
\end{table}

Table \ref{table:kysymys} on page \pageref{table:kysymys} refers to the ...

In the "root" __init__.py you can also do a

import sys
sys.path.insert(1, '.')

which should make both modules importable.

ActionBar ab = getSupportActionBar();
ab.setDisplayShowHomeEnabled(true);
      ab.setDisplayShowCustomEnabled(true);
      setDisplayShowTitleEnabled(true);
      View customView =     getLayoutInflater().inflate(R.layout.activity_main,null); //here activity_main.xml is the GUI design file.
ab.setCustomView(customView);
Toolbar parent =(Toolbar) customView.getParent(); //use V7 Toolbar import
parent.setContentInsetsAbsolute(0, 0);
setPadding(5,0,0,0);

ab.setIcon(R.mipmap.ic_launcher);

I've been looking for better way of doing it recently. Associative array sounded like overkill for me. Look what I found:

4. Close Notepad++ and reopen it. If you have downloaded an incompatible dll, then it will complain, else it will open successfully. If it complains about incompatibility, go back to STEP 1 and download the correct bit version as per your OS. Check Plugins in Notepad++.

5. Paste a sample unformatted but valid JSON data in Notepad++.

6. Select all text in Notepad++ (CTRL+A) and format using Plugins -> JSTool -> JSFormat.

NOTE: On side note, if you do not want to install any plugins like this, I would recommend using the following 2 best online formatters.

I am assuming this is a custom font. For any custom font this is what you do.

1. First download and add your font files to your project in Xcode (The files should appear as well in “Target -> Build Phases -> Copy Bundle Resources”).

2. In your Info.plist file add the key “Fonts provided by application” with type “Array”.

3. For each font you want to add to your project, create an item for the array you have created with the full name of the file including its extension (e.g. HelveticaNeue-UltraLight.ttf). Save your “Info.plist” file.

label.font = UIFont (name: "HelveticaNeue-UltraLight", size: 30)

If you just want to change alignment of text just make a classes

.left {
text-align: left;
}

and span that class through the text

<span class='left'>aligned left</span>

Here is one quick solution with the use of Guava:

import com.google.common.base.Charsets;
import com.google.common.io.Resources;

public String readResource(final String fileName, Charset charset) throws IOException {
        return Resources.toString(Resources.getResource(fileName), charset);
}

Usage:

String fixture = this.readResource("filename.txt", Charsets.UTF_8)

Using the Kotlin Gradle DSL, this solved the issue for me. I added this to the build.gradle.kts. This is in addition to the answer by Joel

man 1 nm

https://web.archive.org/web/20160316222941/https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/nm.1.html

For example:

nm -gU /usr/local/Cellar/cairo/1.12.16/lib/cairo/libcairo-trace.0.dylib

Wouldn't it be better to "wrap" the String in order to memorize the hashCode. In the normal String class hashCode() is O(N) the first time and then it is O(1) since it is kept for future use.

public class HashWrap {
    private final String value;
    private final int hash;

    public String get() {
        return value;
    }

    public HashWrap(String value) {
        this.value = value;
        String lc = value.toLowerCase();
        this.hash = lc.hashCode();
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o instanceof HashWrap) {
            HashWrap that = (HashWrap) o;
            return value.equalsIgnoreCase(that.value);
        } else {
            return false;
        }
    }

    @Override
    public int hashCode() {
        return this.hash;
    }

    //might want to implement compare too if you want to use with SortedMaps/Sets.
}

This would allow you to use any implementation of Hashtable in java and to have O(1) hasCode().

If you are using microsoft query, you can add "?" to your query...

select name from user where id= ?

that will popup a small window asking for the cell/data/etc when you go back to excel.

In the popup window, you can also select "always use this cell as a parameter" eliminating the need to define that cell every time you refresh your data. This is the easiest option.

I made use of sendkeys in shell scripting using a vbsscript file. Below is the code in vbs file,

Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.SendKeys "C:\Demo.txt"
WshShell.SendKeys "{ENTER}"

Below is the selenium code line to run this vbs file,

driver.findElement(By.id("uploadname1")).click();
Thread.sleep(1000);
Runtime.getRuntime().exec( "wscript C:/script.vbs" );

This line:

layout = (LinearLayout) findViewById(R.id.statsviewlayout);

Looks for the "statsviewlayout" id in your current 'contentview'. Now you've set that here:

setContentView(new GraphTemperature(getApplicationContext()));

And i'm guessing that new "graphTemperature" does not set anything with that id.

It's a common mistake to think you can just find any view with findViewById. You can only find a view that is in the XML (or appointed by code and given an id).

The nullpointer will be thrown because the layout you're looking for isn't found, so

layout.addView(buyButton);

Throws that exception.

addition: Now if you want to get that view from an XML, you should use an inflater:

layout = (LinearLayout) View.inflate(this, R.layout.yourXMLYouWantToLoad, null);

assuming that you have your linearlayout in a file called "yourXMLYouWantToLoad.xml"

You can use the lsof command. Let port number like here is 8090

lsof -i:8090

This command returns a list of open processes on this port.

Something like…

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
ssh 75782 eoin 5u IPv6 0x01c1c234 0t0 TCP localhost:8090 (LISTEN)

To free the port, kill the process using it(the process id is 75782)…

kill -9 75782

This one worked for me. here is the link from the original post: link

You probably want os.makedirs as it will create intermediate directories as well, if needed.

import os

#dir is not keyword
def makemydir(whatever):
  try:
    os.makedirs(whatever)
  except OSError:
    pass
  # let exception propagate if we just can't
  # cd into the specified directory
  os.chdir(whatever)

I have use mkcert to create infinites *.dev.net subdomains & localhost with valid HTTPS/SSL certs (Windows 10 XAMPP & Linux Debian 10 Apache2)

I create the certs on Windows with mkcert v1.4.0 (execute CMD as Administrator):

mkcert -install
mkcert localhost "*.dev.net"

This create in Windows 10 this files (I will install it first in Windows 10 XAMPP)

localhost+1.pem
localhost+1-key.pem

Overwrite the XAMPP default certs:

copy "localhost+1.pem" C:\xampp\apache\conf\ssl.crt\server.crt
copy "localhost+1-key.pem"  C:\xampp\apache\conf\ssl.key\server.key

Now, in Apache2 for Debian 10, activate SSL & vhost_alias

a2enmod vhosts_alias
a2enmod ssl
a2ensite default-ssl
systemctl restart apache2

For vhost_alias add this Apache2 config:

nano /etc/apache2/sites-available/999-vhosts_alias.conf

With this content:

<VirtualHost *:80>
   UseCanonicalName Off
   ServerAlias *.dev.net
   VirtualDocumentRoot "/var/www/html/%0/"
</VirtualHost>

Add the site:

a2ensite 999-vhosts_alias

Copy the certs to /root/mkcert by SSH and let overwrite the Debian ones:

systemctl stop apache2

mv /etc/ssl/certs/ssl-cert-snakeoil.pem /etc/ssl/certs/ssl-cert-snakeoil.pem.bak
mv /etc/ssl/private/ssl-cert-snakeoil.key /etc/ssl/private/ssl-cert-snakeoil.key.bak

cp "localhost+1.pem" /etc/ssl/certs/ssl-cert-snakeoil.pem
cp "localhost+1-key.pem" /etc/ssl/private/ssl-cert-snakeoil.key

chown root:ssl-cert /etc/ssl/private/ssl-cert-snakeoil.key
chmod 640 /etc/ssl/private/ssl-cert-snakeoil.key

systemctl start apache2

Edit the SSL config

nano /etc/apache2/sites-enabled/default-ssl.conf

At the start edit the file with this content:

<IfModule mod_ssl.c>
    <VirtualHost *:443>

            UseCanonicalName Off
            ServerAlias *.dev.net
            ServerAdmin webmaster@localhost

            # DocumentRoot /var/www/html/
            VirtualDocumentRoot /var/www/html/%0/

...

Last restart:

systemctl restart apache2

NOTE: don´t forget to create the folders for your subdomains in /var/www/html/

/var/www/html/subdomain1.dev.net
/var/www/html/subdomain2.dev.net
/var/www/html/subdomain3.dev.net

For what it worth, if anyone has this problem only in VSCode, just restart VSCode and it should fix it. Sometimes, Intellisense seems to mess up with imports or types.

Perform a hard reboot of your phone. The easiest way to do this is to remove the phone's battery. Wait for at least 30 seconds, then replace the battery. The phone will reboot, and upon completing its restart will have an empty DNS cache.

EDIT : this answer used to claim that it isn't possible to center an absolutely positioned element with margin: auto;, but this simply isn't true. Because this is the most up-voted and accepted answer, I guessed I'd just change it to be correct.

When you apply the following CSS to an element

position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
margin: auto;

And then give the element a fixed width and height, such as 200px or 40%, the element will center itself.

Here's a Fiddle that demonstrates the effect.

Set the following two environment variables:

NVIDIA_VISIBLE_DEVICES=$gpu_id
CUDA_VISIBLE_DEVICES=0

where gpu_id is the ID of your selected GPU, as seen in the host system's nvidia-smi (a 0-based integer) that will be made available to the guest system (e.g. to the Docker container environment).

You can verify that a different card is selected for each value of gpu_id by inspecting Bus-Id parameter in nvidia-smi run in a terminal in the guest system).

More info

This method based on NVIDIA_VISIBLE_DEVICES exposes only a single card to the system (with local ID zero), hence we also hard-code the other variable, CUDA_VISIBLE_DEVICES to 0 (mainly to prevent it from defaulting to an empty string that would indicate no GPU).

Note that the environmental variable should be set before the guest system is started (so no chances of doing it in your Jupyter Notebook's terminal), for instance using docker run -e NVIDIA_VISIBLE_DEVICES=0 or env in Kubernetes or Openshift.

If you want GPU load-balancing, make gpu_id random at each guest system start.

If setting this with python, make sure you are using strings for all environment variables, including numerical ones.

You can verify that a different card is selected for each value of gpu_id by inspecting nvidia-smi's Bus-Id parameter (in a terminal run in the guest system).

The accepted solution based on CUDA_VISIBLE_DEVICES alone does not hide other cards (different from the pinned one), and thus causes access errors if you try to use them in your GPU-enabled python packages. With this solution, other cards are not visible to the guest system, but other users still can access them and share their computing power on an equal basis, just like with CPU's (verified).

This is also preferable to solutions using Kubernetes / Openshift controlers (resources.limits.nvidia.com/gpu), that would impose a lock on the allocated card, removing it from the pool of available resources (so the number of containers with GPU access could not exceed the number of physical cards).

This has been tested under CUDA 8.0, 9.0 and 10.1 in docker containers running Ubuntu 18.04 orchestrated by Openshift 3.11.

This uses os.listdir and works for any directory:

import os
directory = 'mydirpath'

number_of_files = len([item for item in os.listdir(directory) if os.path.isfile(os.path.join(directory, item))])

this can be simplified with a generator and made a little bit faster with:

import os
isfile = os.path.isfile
join = os.path.join

directory = 'mydirpath'
number_of_files = sum(1 for item in os.listdir(directory) if isfile(join(directory, item)))

We can assign a variable for curl using single quote ' and wrap some other variables in double-single-double quote "'" for substitution inside curl-variable. Then easily we can use that curl-variable which here is MERGE.

Example:

# other variables ... 
REF_NAME="new-branch";

# variable for curl using single quote => ' not double "
MERGE='{
    "repository": "tmp",
    "command": "git",
    "args": [
        "pull",
        "origin",
        "'"$REF_NAME"'"
    ],
    "options": {
        "cwd": "/home/git/tmp"
    }
}';

notice this line:

    "'"$REF_NAME"'"

and then calling curl as usual:

curl -s -X POST localhost:1365/M -H 'Content-Type: application/json' --data "$MERGE" 

You can run IIS on any port you like, as long as it does not conflict with other applications. I am using 88, 8888 and other easy to remember ports.

You can find the common used port here: PORT NUMBERS, and it is safer to choose an unassigned TCP port.

Quote:

The Dynamic and/or Private Ports are those from 49152 through 65535

If IIS is working and you have troubles with an ASP.NET applications, those links might be helpful:

• How to: Configure ASP.NET Applications for an ASP.NET Version
• ASP.NET and IIS Configuration

If you are still having troubles, it would be helpful to provide more information about your environment, the steps taken so far to solve the problem, and retagging the question (append asp.net for example)

I'm amazed by everyone else's MUCH more complicated answers.

XML

You can very simply define the alpha in the color definition of the button (or any other view) in your xml:

android:color="#66FF0000"    // Partially transparent red

In the above example, the color would be a partially transparent red.

When defining the color of a view, the format can be either #RRGGBB or #AARRGGBB, where AA is the hex alpha value. FF would be fully opaque and 00 would be full transparent.

Dynamically

If you need to dynamically alter the opacity in your code, use

myButton.getBackground().setAlpha(128);  // 50% transparent

Where the INT ranges from 0 (fully transparent) to 255 (fully opaque).

    EDIT: See the other answers for better solutions

The original newbie approaches that I offered were (opt1):

$qb->where("e.fecha > '" . $monday->format('Y-m-d') . "'");
$qb->andWhere("e.fecha < '" . $sunday->format('Y-m-d') . "'");

And (opt2):

$qb->add('where', "e.fecha between '2012-01-01' and '2012-10-10'");

That was quick and easy and got the original poster going immediately.

Hence the accepted answer.

As per comments, it is the wrong answer, but it's an easy mistake to make, so I'm leaving it here as a "what not to do!"

It's true that Messagebox.show("dd"); is not a part of using System.Web;,

I felt the same situation for most of time. If you want to do this then do the following steps.

• Right click on project in solution explorer

• go for add reference, then choose .NET tab

• And select, System.windows.forms (press 's' to find quickly)

u can get the namespace, now u can use Messagebox.show("dd");

But I recommend to go with javascript alert for this.

Check for table compatibility. For example, if one table is MyISAM and the other one is InnoDB, you may have this issue.

If you want to avoid using DNS:

List<IPAddress> ipList = new List<IPAddress>();
foreach (var netInterface in NetworkInterface.GetAllNetworkInterfaces())
{
    foreach (var address in netInterface.GetIPProperties().UnicastAddresses)
    {
        if (address.Address.AddressFamily == AddressFamily.InterNetwork)
        {
            Console.WriteLine("found IP " + address.Address.ToString());
            ipList.Add(address.Address);
        }
    }
}

std::less<> when using custom classes with operator<

If you are dealing with a set of your custom class that has operator< defined, then you can just use std::less<>.

As mentioned at http://en.cppreference.com/w/cpp/container/set/find C++14 has added two new find APIs:

template< class K > iterator find( const K& x );
template< class K > const_iterator find( const K& x ) const;

which allow you to do:

main.cpp

#include <cassert>
#include <set>

class Point {
    public:
        // Note that there is _no_ conversion constructor,
        // everything is done at the template level without
        // intermediate object creation.
        //Point(int x) : x(x) {}
        Point(int x, int y) : x(x), y(y) {}
        int x;
        int y;
};
bool operator<(const Point& c, int x) { return c.x < x; }
bool operator<(int x, const Point& c) { return x < c.x; }
bool operator<(const Point& c, const Point& d) {
    return c.x < d;
}

int main() {
    std::set<Point, std::less<>> s;
    s.insert(Point(1, -1));
    s.insert(Point(2, -2));
    s.insert(Point(0,  0));
    s.insert(Point(3, -3));
    assert(s.find(0)->y ==  0);
    assert(s.find(1)->y == -1);
    assert(s.find(2)->y == -2);
    assert(s.find(3)->y == -3);
    // Ignore 1234, find 1.
    assert(s.find(Point(1, 1234))->y == -1);
}

Compile and run:

g++ -std=c++14 -Wall -Wextra -pedantic -o main.out main.cpp
./main.out

More info about std::less<> can be found at: What are transparent comparators?

Tested on Ubuntu 16.10, g++ 6.2.0.

float

Or if you want to go old-school:

real

You can also use float(53), but it means the same thing as float.

("real" is equivalent to float(24), not float/float(53).)

The decimal(x,y) SQL Server type is for when you want exact decimal numbers rather than floating point (which can be approximations). This is in contrast to the C# "decimal" data type, which is more like a 128-bit floating point number.

MSSQL's float type is equivalent to the 64-bit double type in .NET. (My original answer from 2011 said there could be a slight difference in mantissa, but I've tested this in 2020 and they appear to be 100% compatible in their binary representation of both very small and very large numbers -- see https://dotnetfiddle.net/wLX5Ox for my test).

To make things more confusing, a "float" in C# is only 32-bit, so it would be more equivalent in SQL to the real/float(24) type in MSSQL than float/float(53).

In your specific use case... All you need is 5 places after the decimal point to represent latitude and longitude within about one-meter precision, and you only need up to three digits before the decimal point for the degrees. Float(24) or decimal(8,5) will best fit your needs in MSSQL, and using float in C# is good enough, you don't need double. In fact, your users will probably thank you for rounding to 5 decimal places rather than having a bunch of insignificant digits coming along for the ride.

Based on Amith Koujalgi's answer, here's a simple module you can use for logging -

transcript.py:

"""
Transcript - direct print output to a file, in addition to terminal.

Usage:
    import transcript
    transcript.start('logfile.log')
    print("inside file")
    transcript.stop()
    print("outside file")
"""

import sys

class Transcript(object):

    def __init__(self, filename):
        self.terminal = sys.stdout
        self.logfile = open(filename, "a")

    def write(self, message):
        self.terminal.write(message)
        self.logfile.write(message)

    def flush(self):
        # this flush method is needed for python 3 compatibility.
        # this handles the flush command by doing nothing.
        # you might want to specify some extra behavior here.
        pass

def start(filename):
    """Start transcript, appending print output to given filename"""
    sys.stdout = Transcript(filename)

def stop():
    """Stop transcript and return print functionality to normal"""
    sys.stdout.logfile.close()
    sys.stdout = sys.stdout.terminal

There's no need to manually set the colors. Instead, specify a grayscale colormap...

import numpy as np
import matplotlib.pyplot as plt

# Generate data...
x = np.random.random(10)
y = np.random.random(10)

# Plot...
plt.scatter(x, y, c=y, s=500)
plt.gray()

plt.show()

Or, if you'd prefer a wider range of colormaps, you can also specify the cmap kwarg to scatter. To use the reversed version of any of these, just specify the "_r" version of any of them. E.g. gray_r instead of gray. There are several different grayscale colormaps pre-made (e.g. gray, gist_yarg, binary, etc).

import matplotlib.pyplot as plt
import numpy as np

# Generate data...
x = np.random.random(10)
y = np.random.random(10)

plt.scatter(x, y, c=y, s=500, cmap='gray')
plt.show()

Python lists were not made to operate on the beginning of the list and are very ineffective at this operation.

While you can write

mylist = [1, 2 ,3 ,4]
mylist.pop(0)

It's very inefficient.

If you only want to delete items from your list, you can do this with del:

del mylist[:n]

Which is also really fast:

In [34]: %%timeit
help=range(10000)
while help:
    del help[:1000]
   ....:
10000 loops, best of 3: 161 µs per loop

If you need to obtain elements from the beginning of the list, you should use collections.deque by Raymond Hettinger and its popleft() method.

from collections import deque

deque(['f', 'g', 'h', 'i', 'j'])

>>> d.pop()                          # return and remove the rightmost item
'j'
>>> d.popleft()                      # return and remove the leftmost item
'f'

A comparison:

list + pop(0)

In [30]: %%timeit
   ....: help=range(10000)
   ....: while help:
   ....:     help.pop(0)
   ....:
100 loops, best of 3: 17.9 ms per loop

deque + popleft()

In [33]: %%timeit
help=deque(range(10000))
while help:
    help.popleft()
   ....:
1000 loops, best of 3: 812 µs per loop

Use matplotlib's calls that won't block:

Using draw():

from matplotlib.pyplot import plot, draw, show
plot([1,2,3])
draw()
print('continue computation')

# at the end call show to ensure window won't close.
show()

Using interactive mode:

from matplotlib.pyplot import plot, ion, show
ion() # enables interactive mode
plot([1,2,3]) # result shows immediatelly (implicit draw())

print('continue computation')

# at the end call show to ensure window won't close.
show()

I can reproduce your problem if there are no files in the directory that were modified in the last hour. In that case, find . -mmin -60 returns nothing. The command find . -mmin -60 |xargs ls -l, however, returns every file in the directory which is consistent with what happens when ls -l is run without an argument.

To make sure that ls -l is only run when a file is found, try:

find . -mmin -60 -type f -exec ls -l {} +

Now, imagine you want to find a particular Chapter that contains a word "Alchemist". Without an index page, you have no other option than scanning through the entire book/Chapters. i.e: 1000 pages.

This analogy is known as "Full Table Scan" in database world.

But with an index page, you know where to go! And more, to lookup any particular Chapter that matters, you just need to look over the index page, again and again, every time. After finding the matching index you can efficiently jump to that chapter by skipping the rest.

But then, in addition to actual 1000 pages, you will need another ~10 pages to show the indices, so totally 1010 pages.

Thus, the index is a separate section that stores values of indexed column + pointer to the indexed row in a sorted order for efficient look-ups.

Things are simple in schools, isn't it? :P

Well, if it comes from user input then absolutely yes, for obvious reasons. Think if this very website didn't do it: the title of this question would show up as do i really need to encode ‘&’ as ‘&’?

If it's just something like echo '<title>Dolce & Gabbana</title>'; then strictly speaking you don't have to. It would be better, but if you don't no user will notice the difference.

If you're using react-native then please try the below commands first before running your project:

1. npm install --save-dev jetifier
2. npx jetify

Now run your project again. Hope this will work.

You can use : Query grouping allows you to create groups of WHERE clauses by enclosing them in parentheses. This will allow you to create queries with complex WHERE clauses. Nested groups are supported. Example:

$this->db->select('*')->from('my_table')
        ->group_start()
                ->where('a', 'a')
                ->or_group_start()
                        ->where('b', 'b')
                        ->where('c', 'c')
                ->group_end()
        ->group_end()
        ->where('d', 'd')
->get();

If you want to permanently undo it and you have cloned some repository

The commit id can be seen by

git log 

Then you can do -

git reset --hard <commit_id>

git push origin <branch_name> -f

The best thing to do is to install the Tampermonkey extension.

This will allow you to easily install Greasemonkey scripts, and to easily manage them. Also it makes it easier to install userscripts directly from sites like OpenUserJS, MonkeyGuts, etc.

Finally, it unlocks most all of the GM functionality that you don't get by installing a GM script directly with Chrome. That is, more of what GM on Firefox can do, is available with Tampermonkey.

But, if you really want to install a GM script directly, it's easy a right pain on Chrome these days...

Chrome After about August, 2014:

You can still drag a file to the extensions page and it will work... Until you restart Chrome. Then it will be permanently disabled. See Continuing to "protect" Chrome users from malicious extensions for more information. Again, Tampermonkey is the smart way to go. (Or switch browsers altogether to Opera or Firefox.)

Chrome 21+ :

Chrome is changing the way extensions are installed. Userscripts are pared-down extensions on Chrome but. Starting in Chrome 21, link-click behavior is disabled for userscripts. To install a user script, drag the **.user.js* file into the Extensions page (chrome://extensions in the address input).

Older Chrome versions:

Merely drag your **.user.js* files into any Chrome window. Or click on any Greasemonkey script-link.

You'll get an installation warning:

Click Continue.

You'll get a confirmation dialog:

Click Add.

Notes:

1. Scripts installed this way have limitations compared to a Greasemonkey (Firefox) script or a Tampermonkey script. See Cross-browser user-scripting, Chrome section.

Controlling the Script and name:

By default, Chrome installs scripts in the Extensions folder¹, full of cryptic names and version numbers. And, if you try to manually add a script under this folder tree, it will be wiped the next time Chrome restarts.

To control the directories and filenames to something more meaningful, you can:

1. Create a directory that's convenient to you, and not where Chrome normally looks for extensions. For example, Create: C:\MyChromeScripts\.

2. For each script create its own subdirectory. For example, HelloWorld.

3. In that subdirectory, create or copy the script file. For example, Save this question's code as: HelloWorld.user.js.

4. You must also create a manifest file in that subdirectory, it must be named: manifest.json.

   For our example, it should contain:

   {
       "manifest_version": 2,
       "content_scripts": [ {
           "exclude_globs":    [  ],
           "include_globs":    [ "*" ],
           "js":               [ "HelloWorld.user.js" ],
           "matches":          [   "https://stackoverflow.com/*",
                                   "https://stackoverflow.com/*"
                               ],
           "run_at": "document_end"
       } ],
       "converted_from_user_script": true,
       "description":  "My first sensibly named script!",
       "name":         "Hello World",
       "version":      "1"
   }
   

   The manifest.json file is automatically generated from the meta-block by Chrome, when an user script is installed. The values of @include and @exclude meta-rules are stored in include_globs and exclude_globs, @match (recommended) is stored in the matches list. "converted_from_user_script": true is required if you want to use any of the supported GM_* methods.

5. Now, in Chrome's Extension manager (URL = chrome://extensions/), Expand "Developer mode".

6. Click the Load unpacked extension... button.

7. For the folder, paste in the folder for your script, In this example it is: C:\MyChromeScripts\HelloWorld.

8. Your script is now installed, and operational!

9. If you make any changes to the script source, hit the Reload link for them to take effect:

   

¹ The folder defaults to:

Windows XP:
  Chrome  : %AppData%\..\Local Settings\Application Data\Google\Chrome\User Data\Default\Extensions\
  Chromium: %AppData%\..\Local Settings\Application Data\Chromium\User Data\Default\Extensions\

Windows Vista/7/8:
  Chrome  : %LocalAppData%\Google\Chrome\User Data\Default\Extensions\
  Chromium: %LocalAppData%\Chromium\User Data\Default\Extensions\

Linux:
  Chrome  : ~/.config/google-chrome/Default/Extensions/
  Chromium: ~/.config/chromium/Default/Extensions/

Mac OS X:
  Chrome  : ~/Library/Application Support/Google/Chrome/Default/Extensions/
  Chromium: ~/Library/Application Support/Chromium/Default/Extensions/

Although you can change it by running Chrome with the --user-data-dir= option.

The java compiler tries to interpret 600851475143 as a constant value of type int by default. This causes an error since 600851475143 can not be represented with an int.

To tell the compiler that you want the number interpretet as a long you have to add either l or L after it. Your number should then look like this 600851475143L.

Since some Fonts make it hard to distinguish "1" and lower case "l" from each other you should always use the upper case "L".

Here's my solution for Bootstrap 4:

<button id="search" class="btn btn-primary" 
data-loading-text="<i class='fa fa-spinner fa-spin fa-fw' aria-hidden='true'></i>Searching">
  Search
</button>

var setLoading = function () {
  var search = $('#search');
  if (!search.data('normal-text')) {
    search.data('normal-text', search.html());
  }
  search.html(search.data('loading-text'));
};

var clearLoading = function () {
  var search = $('#search');
  search.html(search.data('normal-text'));
};

setInterval(() => {
  setLoading();
  setTimeout(() => {
    clearLoading();
  }, 1000);
}, 2000);

If you want a flat list of all paths under a given dir (like find . in the shell):

   files = [ 
       os.path.join(parent, name)
       for (parent, subdirs, files) in os.walk(YOUR_DIRECTORY)
       for name in files + subdirs
   ]

To only include full paths to files under the base dir, leave out + subdirs.

Use the entity code   instead.

  is a HTML "character entity reference". There is no named entity for non-breaking space in XML, so you use the code  .

Wikipedia includes a list of XML and HTML entities, and you can see that there are only 5 "predefined entities" in XML, but HTML has over 200. I'll also point over to Creating a space (&nbsp;) in XSL which has excellent answers.

pip install --user mysqlclient 

above works for me like charm for me.I go the error from sqlalchemy actually. Environment information :

Python : 3.6, Ubuntu : 16.04,conda 4.6.8

neater:

function BlockID() {
  return {
    "s":"Images/Block_01.png",
    "g":"Images/Block_02.png",
    "C":"Images/Block_03.png",
    "d":"Images/Block_04.png"
   }
}

or just

var images = {
  "s":"Images/Block_01.png",
  "g":"Images/Block_02.png",
  "C":"Images/Block_03.png",
  "d":"Images/Block_04.png"
}

To check whether a process/command returned 0 or not, use the operators && == 0 or not == 0 ||:

Just add operator to your script:

execute_command && (

       echo\Return 0, with no execution error
) || (
        echo\Return non 0, something went wrong
     )

command && echo\Return 0 || echo\Return non 0

• For details on Operators' behavior see: Conditional Execution || && ...

You can collect or set the content of a selected tag.

As a Pseudo idea, its similar to having many boxes within a room and imply the idea 'everything within that box'

As a side note, remember that all this output is generated in the server side.

Using DBMS_OUTPUT, the text is generated in the server while it executes your query and stored in a buffer. It is then redirected to your client app when the server finishes the query data retrieval. That is, you only get this info when the query ends.

With UTL_FILE all the information logged will be stored in a file in the server. When the execution finishes you will have to navigate to this file to get the information.

Hope this helps.

Just like the others said before the way to do this is to press ctrl+w and then o. This will "maximize" the current window, while closing the others. If you'd like to be able to "unmaximize" it, there's a plugin called ZoomWin for that. Otherwise you'd have to recreate the window setup from scratch.

mv file.txt file.tmp && sed 's/foo/bar/g' < file.tmp > file.txt

Should preserve all hardlinks, since output is directed back to overwrite the contents of the original file, and avoids any need for a special version of sed.

$date = "'".date('Y-m-d H:i:s', strtotime(str_replace('-', '/', $_POST['date'])))."'";

How about something like:

\documentclass{article}

\usepackage{amssymb,amsmath}

\begin{document}

\begin{equation}\label{A_Label}
  \begin{split}
    w^T x_i + b \geqslant 1-\xi_i \text{ if } y_i &= 1, \\
    w^T x_i + b \leqslant -1+\xi_i \text{ if } y_i &= -1
  \end{split}
\end{equation}

\end{document}

which produces:

Use positioning. The following worked for me...

With zoom to the center of the image (image fills the div):

div{
    display:block;
    overflow:hidden;
    width: 70px; 
    height: 70px;  
    position: relative;
}
div img{
    min-width: 70px; 
    min-height: 70px;
    max-width: 250%; 
    max-height: 250%;    
    top: -50%;
    left: -50%;
    bottom: -50%;
    right: -50%;
    position: absolute;
}

Without zoom to the center of the image (image does not fill the div):

   div{
        display:block;
        overflow:hidden;
        width: 100px; 
        height: 100px;  
        position: relative;
    }
    div img{
        width: 70px; 
        height: 70px; 
        top: 50%;
        left: 50%;
        bottom: 50%;
        right: 50%;
        position: absolute;
    }

In the root web.config for your project, under the system.web node:

<system.web>
    <httpRuntime maxUrlLength="10999" maxQueryStringLength="2097151" />
...

In addition, I had to add this under the system.webServer node or I got a security error for my long query strings:

<system.webServer>
    <security>
      <requestFiltering>
        <requestLimits maxUrl="10999" maxQueryString="2097151" />
      </requestFiltering>
    </security>
...

This happens because you have added your worker directory as a volume to your docker-compose.yml, as the volume is not mounted during the build.

When docker builds the image, the node_modules directory is created within the worker directory, and all the dependencies are installed there. Then on runtime the worker directory from outside docker is mounted into the docker instance (which does not have the installed node_modules), hiding the node_modules you just installed. You can verify this by removing the mounted volume from your docker-compose.yml.

A workaround is to use a data volume to store all the node_modules, as data volumes copy in the data from the built docker image before the worker directory is mounted. This can be done in the docker-compose.yml like this:

redis:
    image: redis
worker:
    build: ./worker
    command: npm start
    ports:
        - "9730:9730"
    volumes:
        - ./worker/:/worker/
        - /worker/node_modules
    links:
        - redis

I'm not entirely certain whether this imposes any issues for the portability of the image, but as it seems you are primarily using docker to provide a runtime environment, this should not be an issue.

If you want to read more about volumes, there is a nice user guide available here: https://docs.docker.com/userguide/dockervolumes/

EDIT: Docker has since changed it's syntax to require a leading ./ for mounting in files relative to the docker-compose.yml file.

[disclaimer: I'm one of the contributors]

We built a very simple free/opensource component that adds SAML support for ASP.NET apps https://github.com/jitbit/AspNetSaml

Basically it's just one short C# file you can throw into your project (or install via Nuget) and use it with your app

You could try:

Serial.write(13);

Which will provide a carriage return, returning to the start of the line every iteration - which should do what you're chasing? (Especially if everything is fixed width).

For optimal Insertion performance disable the index if that's an option for you. Other than that, better hardware (disk, memory) is also helpful

I just spent some time figure it out. Thoma's answer is not complete. Say your program is test.py, you want to use gpu0 to run this program, and keep other gpus free.

You should write CUDA_VISIBLE_DEVICES=0 python test.py

Notice it's DEVICES not DEVICE

A note about reliability:

Since the newline character is as valid as any in a file name, any solution that relies on lines like the head/tail based ones are flawed.

With GNU ls, another option is to use the --quoting-style=shell-always option and a bash array:

eval "files=($(ls -t --quoting-style=shell-always))"
((${#files[@]} > 0)) && printf '%s\n' "${files[0]}"

(add the -A option to ls if you also want to consider hidden files).

If you want to limit to regular files (disregard directories, fifos, devices, symlinks, sockets...), you'd need to resort to GNU find.

With bash 4.4 or newer (for readarray -d) and GNU coreutils 8.25 or newer (for cut -z):

readarray -t -d '' files < <(
  LC_ALL=C find . -maxdepth 1 -type f ! -name '.*' -printf '%T@/%f\0' |
  sort -rzn | cut -zd/ -f2)

((${#files[@]} > 0)) && printf '%s\n' "${files[0]}"

Or recursively:

readarray -t -d '' files < <(
  LC_ALL=C find . -name . -o -name '.*' -prune -o -type f -printf '%T@%p\0' |
  sort -rzn | cut -zd/ -f2-)

Best here would be to use zsh and its glob qualifiers instead of bash to avoid all this hassle:

Newest regular file in the current directory:

printf '%s\n' *(.om[1])

Including hidden ones:

printf '%s\n' *(D.om[1])

Second newest:

printf '%s\n' *(.om[2])

Check file age after symlink resolution:

printf '%s\n' *(-.om[1])

Recursively:

printf '%s\n' **/*(.om[1])

Also, with the completion system (compinit and co) enabled, Ctrl+Xm becomes a completer that expands to the newest file.

So:

vi Ctrl+Xm

Would make you edit the newest file (you also get a chance to see which it before you press Return).

vi Alt+2Ctrl+Xm

For the second-newest file.

vi *.cCtrl+Xm

for the newest c file.

vi *(.)Ctrl+Xm

for the newest regular file (not directory, nor fifo/device...), and so on.

Assuming your ints are 0, 375, 668,5 and 6:

{
    "Id": "610",
    "Name": "15",
    "Description": "1.99",
    "ItemModList": [
                       0,
                       375,
                       668,
                       5,
                       6
                   ]
}

I suggest that you change "Id": "610" to "Id": 610 since it is a integer/long and not a string. You can read more about the JSON format and examples here http://json.org/

Since git 1.8.5 (Q4 2013):

"git fetch" (hence "git pull" as well) learned to check "fetch.prune" and "remote.*.prune" configuration variables and to behave as if the "--prune" command line option was given.

That means that, if you set remote.origin.prune to true:

git config remote.origin.prune true

Any git fetch or git pull will automatically prune.

Note: Git 2.12 (Q1 2017) will fix a bug related to this configuration, which would make git remote rename misbehave.
See "How do I rename a git remote?".

See more at commit 737c5a9:

Without "git fetch --prune", remote-tracking branches for a branch the other side already has removed will stay forever.
Some people want to always run "git fetch --prune".

To accommodate users who want to either prune always or when fetching from a particular remote, add two new configuration variables "fetch.prune" and "remote.<name>.prune":

• "fetch.prune" allows to enable prune for all fetch operations.
• "remote.<name>.prune" allows to change the behaviour per remote.

The latter will naturally override the former, and the --[no-]prune option from the command line will override the configured default.

Since --prune is a potentially destructive operation (Git doesn't keep reflogs for deleted references yet), we don't want to prune without users consent, so this configuration will not be on by default.

Google Map API request and parse DirectionsResponse with C#, change the json in your url to xml and use the following code to turn the result into a usable C# Generic List Object.

                Lng = r.Elements("lng").Select(s => s.Value).FirstOrDefault()
            }).FirstOrDefault(),
        }).FirstOrDefault()
    }).FirstOrDefault()
}).FirstOrDefault();

I hope this will help someone.

You can try converting your image from tiff to PNG, here is how to do it:

import com.sun.media.jai.codec.ImageCodec;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageEncoder;
import com.sun.media.jai.codec.PNGEncodeParam;
import com.sun.media.jai.codec.TIFFDecodeParam;
import java.awt.image.RenderedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import javaxt.io.Image;

public class ImgConvTiffToPng {

    public static byte[] convert(byte[] tiff) throws Exception {

        byte[] out = new byte[0];
        InputStream inputStream = new ByteArrayInputStream(tiff);

        TIFFDecodeParam param = null;

        ImageDecoder dec = ImageCodec.createImageDecoder("tiff", inputStream, param);
        RenderedImage op = dec.decodeAsRenderedImage(0);

        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

        PNGEncodeParam jpgparam = null;
        ImageEncoder en = ImageCodec.createImageEncoder("png", outputStream, jpgparam);
        en.encode(op);
        outputStream = (ByteArrayOutputStream) en.getOutputStream();
        out = outputStream.toByteArray();
        outputStream.flush();
        outputStream.close();

        return out;

    }

Try add this to your css

#tfl {
display: none !important;
}

Sort by picture and then by activity:

SELECT some_cols
FROM `prefix_users`
WHERE (some conditions)
ORDER BY pic_set, last_activity DESC;

Just call fig.tight_layout() as you normally would. (pyplot is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)

There shouldn't be a difference between the QtAgg backend and the default backend (or if there is, it's a bug).

E.g.

import matplotlib.pyplot as plt

#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so 
#--    we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

plt.show()

Before Tight Layout

After Tight Layout

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

fig.tight_layout()

plt.show()

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

run

sudo find / -name my.cnf

Usually the first result is the correct one. Should be in

/usr/local/etc/

The YouTube URL in src must have and use the embed endpoint instead of watch, so for instance let’s say you want to embed this YouTube video: https://www.youtube.com/watch?v=P6N9782MzFQ (browser's URL).

You should use the embed endpoint, so the URL now should be something like https://www.youtube.com/embed/P6N9782MzFQ. Use this value as the URL in the src attribute inside the iframe tag in your HTML code, for example:

<iframe width="853" height="480" src="https://www.youtube.com/embed/P6N9782MzFQ" frameborder="0" allowfullscreen ng-show="showvideo"></iframe>

So just replace https://www.youtube.com/watch?v= with https://www.youtube.com/embed/ and of course check for your video's ID. In this sample, my video ID is P6N9782MzFQ.

The file needs be writable by the camera, as Praveen pointed out.

In my usage I wanted to store the file in internal storage. I did this with:

Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (i.resolveActivity(getPackageManager()!=null)){
    try{
        cacheFile = createTempFile("img",".jpg",getCacheDir());
        cacheFile.setWritavle(true,false);
    }catch(IOException e){}
    if(cacheFile != null){
        i.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(cacheFile));
        startActivityForResult(i,REQUEST_IMAGE_CAPTURE);
    }
}

Here cacheFile is a global file used to refer to the file which is written. Then in the result method the returned intent is null. Then the method for processing the intent looks like:

protected void onActivityResult(int requestCode,int resultCode,Intent data){
    if(requestCode != RESULT_OK){
        return;
    }
    if(requestCode == REQUEST_IMAGE_CAPTURE){
        try{
            File output = getImageFile();
            if(output != null && cacheFile != null){
                copyFile(cacheFile,output);

                //Process image file stored at output

                cacheFile.delete();
                cacheFile=null;
            }
        }catch(IOException e){}
    }
}

Here getImageFile() is a utility method to name and create the file in which the image should be stored, and copyFile() is a method to copy a file.

For MySQL > 5.1.11 or MariaDB

1. SET GLOBAL log_output = 'TABLE';
2. SET GLOBAL general_log = 'ON';
3. Take a look at the table mysql.general_log

If you want to output to a log file:

1. SET GLOBAL log_output = "FILE";
2. SET GLOBAL general_log_file = "/path/to/your/logfile.log"
3. SET GLOBAL general_log = 'ON';

As mentioned by jeffmjack in comments, these settings will be forgetting before next session unless you edit the configuration files (e.g. edit /etc/mysql/my.cnf, then restart to apply changes).

Now, if you'd like you can tail -f /var/log/mysql/mysql.log

As the other answers said, the function you need is cv2.rectangle(), but keep in mind that the coordinates for the bounding box vertices need to be integers if they are in a tuple, and they need to be in the order of (left, top) and (right, bottom). Or, equivalently, (xmin, ymin) and (xmax, ymax).

Additionally, for our Android friends (API Level 8):

import android.util.Base64

...

Base64.encodeToString(bytes, Base64.DEFAULT);

For Any String try this:

string s = Console.ReadLine();
foreach( char c in s)
{
    Console.WriteLine(System.Convert.ToInt32(c));
}
Console.ReadKey();

You should put your processing into the class constructor or an OnInit hook method.

Better way is to use containsKey method of HashMap. Tomorrow somebody will add null to the Map. You should differentiate between key presence and key has null value.

API Key is your developer key. Hit https://www.googleapis.com/webfonts/v1/webfonts?key= in your browser by enabling web fonts api and you will see result.

You could add justify-content: space-between to the parent element. In doing so, the children flexbox items will be aligned to opposite sides with space between them.

Updated Example

#container {
    width: 500px;
    border: solid 1px #000;
    display: flex;
    justify-content: space-between;
}

#container {_x000D_
    width: 500px;_x000D_
    border: solid 1px #000;_x000D_
    display: flex;_x000D_
    justify-content: space-between;_x000D_
}_x000D_
_x000D_
#a {_x000D_
    width: 20%;_x000D_
    border: solid 1px #000;_x000D_
}_x000D_
_x000D_
#b {_x000D_
    width: 20%;_x000D_
    border: solid 1px #000;_x000D_
    height: 200px;_x000D_
}

<div id="container">_x000D_
    <div id="a">_x000D_
        a_x000D_
    </div>_x000D_
    <div id="b">_x000D_
        b_x000D_
    </div>_x000D_
</div>

You could also add margin-left: auto to the second element in order to align it to the right.

Updated Example

#b {
    width: 20%;
    border: solid 1px #000;
    height: 200px;
    margin-left: auto;
}

#container {_x000D_
    width: 500px;_x000D_
    border: solid 1px #000;_x000D_
    display: flex;_x000D_
}_x000D_
_x000D_
#a {_x000D_
    width: 20%;_x000D_
    border: solid 1px #000;_x000D_
    margin-right: auto;_x000D_
}_x000D_
_x000D_
#b {_x000D_
    width: 20%;_x000D_
    border: solid 1px #000;_x000D_
    height: 200px;_x000D_
    margin-left: auto;_x000D_
}

<div id="container">_x000D_
    <div id="a">_x000D_
        a_x000D_
    </div>_x000D_
    <div id="b">_x000D_
        b_x000D_
    </div>_x000D_
</div>

Interfaces can not contain any implementation (including default values). You need to switch to abstract class.

Make sure the main in public static void main(String[] args) is lower case. For me it didn't work when I had it with capital letter.

It seems if your key is saved in a variable. data.key = value won't work.

You should use data[key] = value

Example:

data = {key1:'v1', key2:'v2'};

var mykey = 'key1'; 
data.mykey = 'newv1';
data[mykey] = 'newV2';

console.log(data);

Result:

{
  "key1": "newV2",
  "key2": "v2",
  "mykey": "newv1"
}

Better use PHP_EOL ("End Of Line") instead. It's cross-platform.

E.g.:

$unit1 = 'paragrahp1';
$unit2 = 'paragrahp2';
echo '<p>' . $unit1 . '</p>' . PHP_EOL;
echo '<p>' . $unit2 . '</p>';

If you have an array you can simply use a for loop. (I'm sorry, but I'm not going to type out the code for a for loop for you.)

Use the String.split()

var array = string.split(',');

As previously mentioned above in the comments - and tested out myself:

This error is rather ambiguous. Therefore, you should check the error.log located at \xampp\apache\logs

When I had this issue, it was because Skype was already listening on port 80 & 445. I was able to get around this by exiting Skype, starting the Apache service, and then restarting Skype. You can check the current port listeners by opening a command prompt and typing Netstat -a

It is also recommended to have User Account Control OFF as it may block some features built into xxamp.

Prior to this though, I had an issue after I modified my Apache httpd.conf file. Reverting those changes (or reinstalling in the user's case) will resolve that issue.

Here's a demo: http://www.w3.org/Style/Examples/007/center-example

A method (JSFiddle example)

CSS:

html, body {
    margin: 0;
    padding: 0;
    width: 100%;
    height: 100%;
    display: table
}
#content {
    display: table-cell;
    text-align: center;
    vertical-align: middle;
}

HTML:

<div id="content">
    Content goes here
</div>

Another method (JSFiddle example)

CSS

body, html, #wrapper {
    width: 100%;
    height: 100%
}
#wrapper {
    display: table
}
#main {
    display: table-cell;
    vertical-align: middle;
    text-align:center
}

HTML

<div id="wrapper">
<div id="main">
    Content goes here
</div>
</div>

create a file named logging.properties in WEB-INF/classes with following content:

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

To be quite honest, regular expressions are not the best idea for this type of parsing. The regular expression you posted will probably work great for simple cases, but if things get more complex you are going to have huge problems (same reason why you cant reliably parse HTML with regular expressions). I know you probably don't want to hear this, I know I didn't when I asked the same type of questions, but string parsing became WAY more reliable for me after I stopped trying to use regular expressions for everything.

jTopas is an AWESOME tokenizer that makes it quite easy to write parsers by hand (I STRONGLY suggest jtopas over the standard java scanner/etc.. libraries). If you want to see jtopas in action, here are some parsers I wrote using jTopas to parse this type of file

If you are parsing XML files, you should be using an xml parser library. Dont do it youself unless you are just doing it for fun, there are plently of proven options out there

Store your zipcodes as CHAR(5) instead of a numeric type, or have your application pad it with zeroes when you load it from the DB. A way to do it with PHP using sprintf():

echo sprintf("%05d", 205); // prints 00205
echo sprintf("%05d", 1492); // prints 01492

Or you could have MySQL pad it for you with LPAD():

SELECT LPAD(zip, 5, '0') as zipcode FROM table;

Here's a way to update and pad all rows:

ALTER TABLE `table` CHANGE `zip` `zip` CHAR(5); #changes type
UPDATE table SET `zip`=LPAD(`zip`, 5, '0'); #pads everything

For new docker versions we need to use data-root as graph is deprecated in v17.05.0: official deprecated docs

Edit /etc/docker/daemon.json (if it doesn’t exist, create it) and include:

{
  "data-root": "/new/path/to/docker-data"
}

Then restart Docker with:

sudo systemctl daemon-reload
sudo systemctl restart docker

• A more detailed step-by-step explanation (including moving data) using Docker Storage with data-root can be found in: Blog post
• In case of Windows a similar post Windows specific

I had a simular need. Here is what I did:

  <script type="text/javascript" language="javascript">
    function convertEnterToTab() {
      if(event.keyCode==13) {
        event.keyCode = 9;
      }
    }
    document.onkeydown = convertEnterToTab;    
  </script>  

I would override your Tuple with a proper GetHashCode, and just use it as the key.

As long as you overload the proper methods, you should see decent performance.

SELECT CONVERT(VARCHAR(10), GETDATE(), 105) + ' ' + CONVERT(VARCHAR(10), GETDATE(), 108)

The ? is to allow Parameterized Query. These parameterized query is to allow type-specific value when replacing the ? with their respective value.

That's all to it.

Here's a reason of why it's better to use Parameterized Query. Basically, it's easier to read and debug.

One thing that should be considered is licensing.

Notepad++ is free (as in speech and as in beer) for perpetual use, released under the GPL license, whereas Sublime Text 2 requires a license.

To quote the Sublime Text 2 website:

..a license must be purchased for continued use. There is currently no enforced time limit for the evaluation.

The same is now true of Sublime Text 3, and a paid upgrade will be needed for future versions.

Upgrade Policy A license is valid for Sublime Text 3, and includes all point updates, as well as access to prior versions (e.g., Sublime Text 2). Future major versions, such as Sublime Text 4, will be a paid upgrade.

This licensing requirement is still correct as of Dec 2019.

Just tested and this works:

public class Coordinates {
    byte red;

    @JsonProperty("r")
    public byte getR() {
      return red;
    }

    @JsonProperty("red")
    public void setRed(byte red) {
      this.red = red;
    }
}

The idea is that method names should be different, so jackson parses it as different fields, not as one field.

Here is test code:

Coordinates c = new Coordinates();
c.setRed((byte) 5);

ObjectMapper mapper = new ObjectMapper();
System.out.println("Serialization: " + mapper.writeValueAsString(c));

Coordinates r = mapper.readValue("{\"red\":25}",Coordinates.class);
System.out.println("Deserialization: " + r.getR());

Result:

Serialization: {"r":5}
Deserialization: 25

HTML CODE

<div id="borderLoader"  data-height="230px" data-color="lightgrey" data- 
width="230px" data-image="https://fiverr- res.cloudinary.com/t_profile_thumb,q_auto,f_auto/attachments/profile/photo/a54f24b2ab6f377ea269863cbf556c12-619447411516923848661/913d6cc9-3d3c-4884-ac6e-4c2d58ee4d6a.jpg">

</div>

JS CODE

var dataValue, dataSet,key;
dataValue = document.getElementById('borderLoader');
//data set contains all the dataset that you are to style the shape;
dataSet ={ 
   "height":dataValue.dataset.height,
   "width":dataValue.dataset.width,
   "color":dataValue.dataset.color,
   "imageBg":dataValue.dataset.image
};

dataValue.style.height = dataSet.height;
dataValue.style.width = dataSet.width;
dataValue.style.background = "#f3f3f3 url("+dataSet.imageBg+") no-repeat 
center";

There is absolutely no way to achieve what you want through CSS alone while supporting pre-flexbox user agents (mostly old IE) -- unless:

1. You know the exact rendered height of each element (if so, you can absolutely position the content). If you're dealing with dynamically generated content, you're out of luck.
2. You know the exact number of these elements there will be. Again, if you need to do this for several chunks of content that are generated dynamically, you're out of luck, especially if there are more than three or so.

If the above are true then you can do what you want by absolutely positioning the elements --

#wrapper { position: relative; }
#firstDiv { position: absolute; height: 100px; top: 110px; }
#secondDiv { position: absolute; height: 100px; top: 0; }

Again, if you don't know the height want for at least #firstDiv, there's no way you can do what you want via CSS alone. If any of this content is dynamic, you will have to use javascript.

I agree with several of the points I've read in this post and I've incorporated them into my solution to solve the exact same issue as the original posting.

That said, the comments I appreciated are:

• "unless you are using .NET 1.0 or 1.1, use List<T> instead of ArrayList. "

• "Also, add the item(s) to be deleted to a new list. Then go through and delete those items." .. in my case I just created a new List and the populated it with the valid data values.

e.g.

private List<string> managedLocationIDList = new List<string>();
string managedLocationIDs = ";1321;1235;;" // user input, should be semicolon seperated list of values

managedLocationIDList.AddRange(managedLocationIDs.Split(new char[] { ';' }));
List<string> checkLocationIDs = new List<string>();

// Remove any duplicate ID's and cleanup the string holding the list if ID's
Functions helper = new Functions();
checkLocationIDs = helper.ParseList(managedLocationIDList);

...
public List<string> ParseList(List<string> checkList)
{
    List<string> verifiedList = new List<string>();

    foreach (string listItem in checkList)
    if (!verifiedList.Contains(listItem.Trim()) && listItem != string.Empty)
        verifiedList.Add(listItem.Trim());

    verifiedList.Sort();
    return verifiedList;
}        

Return types using arrow notation is the same as previous answers:

const sum = (a: number, b: number) : number => a + b;

Something like this will work:

>>> import os
>>> path = '/usr/share/cups/charmaps'
>>> text_files = [f for f in os.listdir(path) if f.endswith('.txt')]
>>> text_files
['euc-cn.txt', 'euc-jp.txt', 'euc-kr.txt', 'euc-tw.txt', ... 'windows-950.txt']

you can generate curl error after its execution

$url = 'http://example.com';

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
if(curl_errno($ch)){
    echo 'Request Error:' . curl_error($ch);
}

and here are curl error code

Run the command on cmd as Administrator otherwise you will get this error :-

You should add reference to PresentationCore.dll.

Each thread in a Java application has its own stack. The stack is used to hold return addresses, function/method call arguments, etc. So if a thread tends to process large structures via recursive algorithms, it may need a large stack for all those return addresses and such. With the Sun JVM, you can set that size via that parameter.

The datetime class has a method strftime. The Python docs documents the different formats it accepts:

• Python 2: strftime() Behavior
• Python 3: strftime() Behavior

For this specific example, it would look something like:

my_datetime.strftime("%B %d, %Y")

Examples

take

Example 1.

take only takes as much as it can get

take(10, range( {from: 100, step: 5, to: 120} ) )

returns

[100, 105, 110, 115, 120]

Example 2.

to not neccesary

take(10, range( {from: 100, step: 5} ) )

returns

[100, 105, 110, 115, 120, 125, 130, 135, 140, 145]

takeAll

Example 3.

from not neccesary

takeAll( range( {to: 5} ) )

returns

[0, 1, 2, 3, 4, 5]

Example 4.

takeAll( range( {to: 500, step: 100} ) )

returns

[0, 100, 200, 300, 400, 500]

Example 5.

takeAll( range( {from: 'z', to: 'a'} ) )

returns

["z", "y", "x", "w", "v", "u", "t", "s", "r", "q", "p", "o", "n", "m", "l", "k", "j", "i", "h", "g", "f", "e", "d", "c", "b", "a"]

I also wondered what had happened to the text editor in console mode in windows. I remembered the famous mc from Linux. Of course, it's available for Windows!

GNU Midnight Commander is a visual file manager, licensed under GNU General Public License and therefore qualifies as Free Software. It's a feature rich full-screen text mode application that allows you to copy, move and delete files and whole directory trees, search for files and run commands in the subshell. Internal viewer and editor are included.

Midnight Commander is based on versatile text interfaces, such as Ncurses or S-Lang, which allows it to work on a regular console, inside an X Window terminal, over SSH connections and all kinds of remote shells.

As mentioned somewhere there are also FAR Manager

push does not return the array, but the length of it (docs), so what you are doing is replacing the array with its length, losing the only reference to it that you had. Try this:

import {ADD_ITEM} from '../Actions/UserActions'
const initialUserState = {

    arr:[]
}

export default function userState(state = initialUserState, action){
     console.log(arr);
     switch (action.type){
        case ADD_ITEM :
          return { 
             ...state,
             arr:[...state.arr, action.newItem]
        }

        default:return state
     }
}

Remember that you must first load jquery script and then the script js

<script type="text/javascript" src="http://code.jquery.com/jquery-2.2.4.min.js"></script>
<script type="text/javascript" src="example.js"></script>

Html is read sequentially!

I had the same problem and was able to run a schema-less query using an existing Mongoose connection with the code below. I've added a simple constraint 'a=b' to show where you would add such a constraint:

var action = function (err, collection) {
    // Locate all the entries using find
    collection.find({'a':'b'}).toArray(function(err, results) {
        /* whatever you want to do with the results in node such as the following
             res.render('home', {
                 'title': 'MyTitle',
                 'data': results
             });
        */
    });
};

mongoose.connection.db.collection('question', action);

If you are looking for a programmatical modal creation, you might love this:

http://nakupanda.github.io/bootstrap3-dialog/

Even though Bootstrap's modal provides a javascript way for modal creation, you still need to write modal's html markups first.

I think we can write like this : $this->db->where('accommodation >=', minvalue); $this->db->where('accommodation <=', maxvalue);

//without dollar($) sign It's work for me :)

This is what I'm using:

private static final String HEX = "0123456789ABCDEF";

public static String encodeURIComponent(String str) {
    if (str == null) return null;

    byte[] bytes = str.getBytes(StandardCharsets.UTF_8);
    StringBuilder builder = new StringBuilder(bytes.length);

    for (byte c : bytes) {
        if (c >= 'a' ? c <= 'z' || c == '~' :
            c >= 'A' ? c <= 'Z' || c == '_' :
            c >= '0' ? c <= '9' :  c == '-' || c == '.')
            builder.append((char)c);
        else
            builder.append('%')
                   .append(HEX.charAt(c >> 4 & 0xf))
                   .append(HEX.charAt(c & 0xf));
    }

    return builder.toString();
}

It goes beyond Javascript's by percent-encoding every character that is not an unreserved character according to RFC 3986.

This is the oposite conversion:

public static String decodeURIComponent(String str) {
    if (str == null) return null;

    int length = str.length();
    byte[] bytes = new byte[length / 3];
    StringBuilder builder = new StringBuilder(length);

    for (int i = 0; i < length; ) {
        char c = str.charAt(i);
        if (c != '%') {
            builder.append(c);
            i += 1;
        } else {
            int j = 0;
            do {
                char h = str.charAt(i + 1);
                char l = str.charAt(i + 2);
                i += 3;

                h -= '0';
                if (h >= 10) {
                    h |= ' ';
                    h -= 'a' - '0';
                    if (h >= 6) throw new IllegalArgumentException();
                    h += 10;
                }

                l -= '0';
                if (l >= 10) {
                    l |= ' ';
                    l -= 'a' - '0';
                    if (l >= 6) throw new IllegalArgumentException();
                    l += 10;
                }

                bytes[j++] = (byte)(h << 4 | l);
                if (i >= length) break;
                c = str.charAt(i);
            } while (c == '%');
            builder.append(new String(bytes, 0, j, UTF_8));
        }
    }

    return builder.toString();
}

How do I change Android Studio editor's background color?

Changing Editor's Background

Open Preference > Editor (In IDE Settings Section) > Colors & Fonts > Darcula or Any item available there

IDE will display a dialog like this, Press 'No'

Darcula color scheme has been set for editors. Would you like to set Darcula as default Look and Feel?

Changing IDE's Theme

Open Preference > Appearance (In IDE Settings Section) > Theme > Darcula or Any item available there

Press OK. Android Studio will ask you to restart the IDE.

The dir wrapper can wrap, any other step, and it all works inside a steps block, for example:

steps {
    sh "pwd"
    dir('your-sub-directory') {
      sh "pwd"
    }
    sh "pwd"
} 

Like others suggested you are better off using collection. If you however for some reason must stick to array then Apache Commons ArrayUtils may help:

int[] series = {4,2};
series = ArrayUtils.add(series, 3); // series is now {4,2,3}
series = ArrayUtils.add(series, 4); // series is now {4,2,3,4};

Note that the add method creates a new array, copies the given array and appends the new element at the end, which may have impact on performance.

Just add this attribute to your toolbar

app:title=" "

Use Math.Max:

int x = 3, y = 4, z = 5;
Console.WriteLine(Math.Max(Math.Max(x, y), z));

in my case, i was sure that the action is correct, but i was passing wrong URL, i passed the website link without the http:// in it's beginning, so it caused the same issue, here is my manifest (part of it)

<activity
        android:name=".MyBrowser"
        android:label="MyBrowser Activity" >
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <action android:name="com.dsociety.activities.MyBrowser" />

            <category android:name="android.intent.category.DEFAULT" />

            <data android:scheme="http" />
        </intent-filter>
    </activity>

when i code the following, the same Exception is thrown at run time :

Intent intent = new Intent();
intent.setAction("com.dsociety.activities.MyBrowser");
intent.setData(Uri.parse("www.google.com"));    // should be http://www.google.com
startActivity(intent);

If you are using SQL Server 2008+, consider the TIME datatype. SQLTeam article with more usage examples.

When working with async functions or observables provided by 3rd party libraries, for example Cloud firestore, I've found functions the waitFor method shown below (TypeScript, but you get the idea...) to be helpful when you need to wait on some process to complete, but you don't want to have to embed callbacks within callbacks within callbacks nor risk an infinite loop.

This method is sort of similar to a while (!condition) sleep loop, but yields asynchronously and performs a test on the completion condition at regular intervals till true or timeout.

export const sleep = (ms: number) => {
    return new Promise(resolve => setTimeout(resolve, ms))
}
/**
 * Wait until the condition tested in a function returns true, or until 
 * a timeout is exceeded.
 * @param interval The frenequency with which the boolean function contained in condition is called.
 * @param timeout  The maximum time to allow for booleanFunction to return true
 * @param booleanFunction:  A completion function to evaluate after each interval. waitFor will return true as soon as the completion function returns true.   
 */
export const waitFor = async function (interval: number, timeout: number,
    booleanFunction: Function): Promise<boolean> {
    let elapsed = 1;
    if (booleanFunction()) return true;
    while (elapsed < timeout) {
        elapsed += interval;
        await sleep(interval);
        if (booleanFunction()) {
            return true;
        }
    }
    return false;
}

The say you have a long running process on your backend you want to complete before some other task is undertaken. For example if you have a function that totals a list of accounts, but you want to refresh the accounts from the backend before you calculate, you can do something like this:

async recalcAccountTotals() : number {
     this.accountService.refresh();   //start the async process.
     if (this.accounts.dirty) {
           let updateResult = await waitFor(100,2000,()=> {return !(this.accounts.dirty)})
     }
 if(!updateResult) { 
      console.error("Account refresh timed out, recalc aborted");
      return NaN;
    }
 return ... //calculate the account total. 
}

!=

For example,

if ("apple" != "orange")
  // true, the string "apple" is not equal to the string "orange"

Means not. See also the logical operators list. Also, when you see triple characters, it's a type sensitive comparison. (e.g. if (1 === '1') [not equal])

path = "C:\\Users\\Programming\\Downloads"
# Replace \\ with a \ along with any random key multiple times
path.replace('\\', '\pppyyyttthhhooonnn')
# Now replace pppyyyttthhhooonnn with a blank string
path.replace("pppyyyttthhhooonnn", "")

print(path)

#Output... C:\Users\Programming\Downloads

I might be wrong on this but I think you need to implement your own com.android.volley.toolbox.HttpStack for this because the default ones (HurlStack if version > Gingerbread or HttpClientStack) don't deal with multipart/form-data.

Edit:

And indeed I was wrong. I was able to do it using MultipartEntity in Request like this:

public class MultipartRequest extends Request<String> {

    private MultipartEntity entity = new MultipartEntity();

    private static final String FILE_PART_NAME = "file";
    private static final String STRING_PART_NAME = "text";

    private final Response.Listener<String> mListener;
    private final File mFilePart;
    private final String mStringPart;

    public MultipartRequest(String url, Response.ErrorListener errorListener, Response.Listener<String> listener, File file, String stringPart)
    {
        super(Method.POST, url, errorListener);

        mListener = listener;
        mFilePart = file;
        mStringPart = stringPart;
        buildMultipartEntity();
    }

    private void buildMultipartEntity()
    {
        entity.addPart(FILE_PART_NAME, new FileBody(mFilePart));
        try
        {
            entity.addPart(STRING_PART_NAME, new StringBody(mStringPart));
        }
        catch (UnsupportedEncodingException e)
        {
            VolleyLog.e("UnsupportedEncodingException");
        }
    }

    @Override
    public String getBodyContentType()
    {
        return entity.getContentType().getValue();
    }

    @Override
    public byte[] getBody() throws AuthFailureError
    {
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        try
        {
            entity.writeTo(bos);
        }
        catch (IOException e)
        {
            VolleyLog.e("IOException writing to ByteArrayOutputStream");
        }
        return bos.toByteArray();
    }

    @Override
    protected Response<String> parseNetworkResponse(NetworkResponse response)
    {
        return Response.success("Uploaded", getCacheEntry());
    }

    @Override
    protected void deliverResponse(String response)
    {
        mListener.onResponse(response);
    }
}

It's pretty raw but I tried it with an image and a simple string and it works. The response is a placeholder, doesn't make much sense to return a Response String in this case. I had problems using apache httpmime to use MultipartEntity so I used this https://code.google.com/p/httpclientandroidlib/ don't know if there's a better way. Hope it helps.

Edit

You can use httpmime without using httpclientandroidlib, the only dependency is httpcore.

^{Note: Though my original answer attracted several upvotes, I decided that I could do much better. You can find my original (simplistic and misguided) answer in the edit history.}

If Microsoft had the intent of providing a means of outputting a blank line from cmd.exe, Microsoft surely would have documented such a simple operation. It is this omission that motivated me to ask this question.

So, because a means for outputting a blank line from cmd.exe is not documented, arguably one should consider any suggestion for how to accomplish this to be a hack. That means that there is no known method for outputting a blank line from cmd.exe that is guaranteed to work (or work efficiently) in all situations.

With that in mind, here is a discussion of methods that have been recommended for outputting a blank line from cmd.exe. All recommendations are based on variations of the echo command.

echo.

While this will work in many if not most situations, it should be avoided because it is slower than its alternatives and actually can fail (see here, here, and here). Specifically, cmd.exe first searches for a file named echo and tries to start it. If a file named echo happens to exist in the current working directory, echo. will fail with:

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

echo:
echo\

At the end of this answer, the author argues that these commands can be slow, for instance if they are executed from a network drive location. A specific reason for the potential slowness is not given. But one can infer that it may have something to do with accessing the file system. (Perhaps because : and \ have special meaning in a Windows file system path?)

However, some may consider these to be safe options since : and \ cannot appear in a file name. For that or another reason, echo: is recommended by SS64.com here.

echo(
echo+
echo,
echo/
echo;
echo=
echo[
echo]

This lengthy discussion includes what I believe to be all of these. Several of these options are recommended in this SO answer as well. Within the cited discussion, this post ends with what appears to be a recommendation for echo( and echo:.

My question at the top of this page does not specify a version of Windows. My experimentation on Windows 10 indicates that all of these produce a blank line, regardless of whether files named echo, echo+, echo,, ..., echo] exist in the current working directory. (Note that my question predates the release of Windows 10. So I concede the possibility that older versions of Windows may behave differently.)

In this answer, @jeb asserts that echo( always works. To me, @jeb's answer implies that other options are less reliable but does not provide any detail as to why that might be. Note that @jeb contributed much valuable content to other references I have cited in this answer.

Conclusion: Do not use echo.. Of the many other options I encountered in the sources I have cited, the support for these two appears most authoritative:

echo(
echo:

But I have not found any strong evidence that the use of either of these will always be trouble-free.

Example Usage:

@echo off
echo Here is the first line.
echo(
echo There is a blank line above this line.

Expected output:

Here is the first line.

There is a blank line above this line.

I found out another solution for this case without using Reactivex neither services. I actually love the rxjx API however I think it goes best when resolving an async and/or complex function. Using It in that way, Its pretty exceeded to me.

What I think you are looking for is for a broadcast. Just that. And I found out this solution:

<app>
  <app-nav (selectedTab)="onSelectedTab($event)"></app-nav>
       // This component bellow wants to know when a tab is selected
       // broadcast here is a property of app component
  <app-interested [broadcast]="broadcast"></app-interested>
</app>

 @Component class App {
   broadcast: EventEmitter<tab>;

   constructor() {
     this.broadcast = new EventEmitter<tab>();
   }

   onSelectedTab(tab) {
     this.broadcast.emit(tab)
   }    
 }

 @Component class AppInterestedComponent implements OnInit {
   broadcast: EventEmitter<Tab>();

   doSomethingWhenTab(tab){ 
      ...
    }     

   ngOnInit() {
     this.broadcast.subscribe((tab) => this.doSomethingWhenTab(tab))
   }
 }

After adding php directory in User Settings,

{
    "php.validate.executablePath": "C:/phpdirectory/php7.1.8/php.exe",
    "php.executablePath": "C:/phpdirectory/php7.1.8/php.exe"
}

If you still have this error, please verify you have installed :

• 64-bit or 32-bit version of php (x64 or x86), depending on your OS;

• some librairies like Visual C++ Redistributable for Visual Studio 2015 : http://www.microsoft.com/en-us/download/details.aspx?id=48145;

To test if you PHP exe is ok, open cmd.exe :

c:/prog/php-7.1.8-Win32-VC14-x64/php.exe --version

If PHP fails, a message will be prompted with the error (missing dll for example).

Warning: this is a convenience method to convert a JSON string to a dictionary if, for some reason, you have to work from a JSON string. But if you have the JSON data available, you should instead work with the data, without using a string at all.

Swift 3

func convertToDictionary(text: String) -> [String: Any]? {
    if let data = text.data(using: .utf8) {
        do {
            return try JSONSerialization.jsonObject(with: data, options: []) as? [String: Any]
        } catch {
            print(error.localizedDescription)
        }
    }
    return nil
}

let str = "{\"name\":\"James\"}"

let dict = convertToDictionary(text: str)

Swift 2

func convertStringToDictionary(text: String) -> [String:AnyObject]? {
    if let data = text.dataUsingEncoding(NSUTF8StringEncoding) {
        do {
            return try NSJSONSerialization.JSONObjectWithData(data, options: []) as? [String:AnyObject]
        } catch let error as NSError {
            print(error)
        }
    }
    return nil
}

let str = "{\"name\":\"James\"}"

let result = convertStringToDictionary(str)

Original Swift 1 answer:

func convertStringToDictionary(text: String) -> [String:String]? {
    if let data = text.dataUsingEncoding(NSUTF8StringEncoding) {
        var error: NSError?
        let json = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.allZeros, error: &error) as? [String:String]
        if error != nil {
            println(error)
        }
        return json
    }
    return nil
}

let str = "{\"name\":\"James\"}"

let result = convertStringToDictionary(str) // ["name": "James"]

if let name = result?["name"] { // The `?` is here because our `convertStringToDictionary` function returns an Optional
    println(name) // "James"
}

In your version, you didn't pass the proper parameters to NSJSONSerialization and forgot to cast the result. Also, it's better to check for the possible error. Last note: this works only if your value is a String. If it could be another type, it would be better to declare the dictionary conversion like this:

let json = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.allZeros, error: &error) as? [String:AnyObject]

and of course you would also need to change the return type of the function:

func convertStringToDictionary(text: String) -> [String:AnyObject]? { ... }

To create a "drop down menu" you can use OptionMenu in tkinter

Example of a basic OptionMenu:

from Tkinter import *

master = Tk()

variable = StringVar(master)
variable.set("one") # default value

w = OptionMenu(master, variable, "one", "two", "three")
w.pack()

mainloop()

More information (including the script above) can be found here.

Creating an OptionMenu of the months from a list would be as simple as:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

mainloop()

In order to retrieve the value the user has selected you can simply use a .get() on the variable that we assigned to the widget, in the below case this is variable:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

def ok():
    print ("value is:" + variable.get())

button = Button(master, text="OK", command=ok)
button.pack()

mainloop()

I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.

A couple things

(a) you cant have both background-color and background, background will always win. in the example below, i combined them through shorthand, but this will produce the color only as a fallback method when the image does not show.

(b) no-scroll does not work, i don't believe it is a valid property of a background-image. try something like fixed:

.button:after {
    content: "";
    width: 30px;
    height: 30px;
    background:red url("http://www.gentleface.com/i/free_toolbar_icons_16x16_black.png") no-repeat -30px -50px fixed;
    top: 10px;
    right: 5px;
    position: absolute;
    display: inline-block;
}

I updated your jsFiddle to this and it showed the image.

What about just using virtual desktops? You can spread your windows around among multiple workspaces. Something like Virtual Dimension should give you most of that functionality. I use virtual desktops all the time on Linux, and it's the next best thing to multiple monitors.

We use GIT as CVS and gradle as build tool.

Symptom

In my case one specific project with > 20'000 files froze using hierarchical view when navigating a directory with a lot of files.

Fix

1. Create new Eclipse workspace
2. Freshly clone the project into the Eclipse workspace
3. Import project into Eclipse (in our case using Gradle import)

Use the strpos function: http://php.net/manual/en/function.strpos.php

$haystack = "foo bar baz";
$needle   = "bar";

if( strpos( $haystack, $needle ) !== false) {
    echo "\"bar\" exists in the haystack variable";
}

In your case:

if( strpos( $a, 'some text' ) !== false ) echo 'text';

Note that my use of the !== operator (instead of != false or == true or even just if( strpos( ... ) ) {) is because of the "truthy"/"falsy" nature of PHP's handling of the return value of strpos.

As of PHP 8.0.0 you can now use str_contains

<?php
    if (str_contains('abc', '')) {
        echo "Checking the existence of the empty string will always 
        return true";
    }

I don't know if maybe it's a difference in Excel version but this question is 6 years old and the accepted answer didn't help me so this is what I figured out:

Under Conditional Formatting > Manage Rules:

1. Make a new rule with "Use a formula to determine which cells to format"
2. Make your rule, but put a dollar sign only in front of the letter: $A2<$B2
3. Under "Applies to", Manually select the second column (It would not work for me if I changed the value in the box, it just kept snapping back to what was already there), so it looks like $B$2:$B$100 (assuming you have 100 rows)

This worked for me in Excel 2016.

In a previous project I found that changing from *-imports to specific imports reduced compilation time by half (from about 10 minutes to about 5 minutes). The *-import makes the compiler search each of the packages listed for a class matching the one you used. While this time can be small, it adds up for large projects.

A side affect of the *-import was that developers would copy and paste common import lines rather than think about what they needed.
