use Contains of jquery Contains like this

if ($('.type:contains("> <")').length > 0)
{
 //do stuffs to change 
}

Here is the simplest example that has the key lines of code:

import numpy as np 
import matplotlib.pyplot as plt

H = np.array([[1, 2, 3, 4],
          [5, 6, 7, 8],
          [9, 10, 11, 12],
          [13, 14, 15, 16]])

plt.imshow(H, interpolation='none')
plt.show()

I found this official tool from facebook developer page, this page will you following information related to access token - App ID, Type, App-Scoped,User last installed this app via, Issued, Expires, Data Access Expires, Valid, Origin, Scopes. Just need access token.

https://developers.facebook.com/tools/debug/accesstoken/

As per @Nitsew's answer, Create your personal access token and use your token as your username and enter with blank password.

Later you won't need any credentials to access all your private repo(s).

Selenium 4 is already included this feature now, you can directly 
open new Tab or new Window with any URL. 

WebDriverManager.chromedriver().setup();

driver = new ChromeDriver(options);

driver.get("www.Url1.com");     
//  below code will open Tab for you as well as switch the control to new Tab
driver.switchTo().newWindow(WindowType.TAB);

// below code will navigate you to your desirable Url 
driver.get("www.Url2.com");

Serialisation in java is not meant as long term persistence or transport format - it is too fragile for this. With the slightest difference in class bytecode and JVM, your data is not readable anymore. Use XML or JSON data-binding for your task (XStream is fast and easy to use, and there are a ton of alternatives)

I think you misunderstand Unicode and its relationship to Perl. No matter which way you store data, Unicode, ISO-8859-1, or many other things, your program has to know how to interpret the bytes it gets as input (decoding) and how to represent the information it wants to output (encoding). Get that interpretation wrong and you garble the data. There isn't some magic default setup inside your program that's going to tell the stuff outside your program how to act.

You think it's hard, most likely, because you are used to everything being ASCII. Everything you should have been thinking about was simply ignored by the programming language and all of the things it had to interact with. If everything used nothing but UTF-8 and you had no choice, then UTF-8 would be just as easy. But not everything does use UTF-8. For instance, you don't want your input handle to think that it's getting UTF-8 octets unless it actually is, and you don't want your output handles to be UTF-8 if the thing reading from them can't handle UTF-8. Perl has no way to know those things. That's why you are the programmer.

I don't think Unicode in Perl 5 is too complicated. I think it's scary and people avoid it. There's a difference. To that end, I've put Unicode in Learning Perl, 6th Edition, and there's a lot of Unicode stuff in Effective Perl Programming. You have to spend the time to learn and understand Unicode and how it works. You're not going to be able to use it effectively otherwise.

You can actually index directly into the Attributes collection (if you are using C# not VB):

foreach (XmlNode xNode in nodeListName)
{
  XmlNode parent = xNode.ParentNode;
  if (parent.Attributes != null
     && parent.Attributes["split"] != null)
  {
     parentSplit = parent.Attributes["split"].Value;
  }
}

Postgresql does not have an equivalent of Oracle's ROWNUM. In many cases you can achieve the same result by using LIMIT and OFFSET in your query.

Just some other formatting options:

printf("name: %s\targs: %s\tvalue %d\tarraysize %d\n", 
        a,        b,        c,        d);

printf("name: %s\targs: %s\tvalue %d\tarraysize %d\n", 
              a,        b,        c,            d);

printf("name: %s\t"      "args: %s\t"      "value %d\t"      "arraysize %d\n", 
        very_long_name_a, very_long_name_b, very_long_name_c, very_long_name_d);

You can add variations on the theme. The idea is that the printf() conversion speficiers and the respective variables are all lined up "nicely" (for some values of "nicely").

Many solutions have been given, and the internals are briefly touched by @Sriram and @ptomli as well. I just want to add a few references to the source code to help understand what is happening under the hood.

By default (i.e. no extra annotations used at all except @XmlRootElement on the root class), JABX tries to marshal things exposed via two ways:

1. public fields
2. getter methods that are named following the convention and have a corresponding setter method.

Notice that if a field is (or method returns) null, it will not be written into the output.

Now if @XmlElement is used, non-public things (could be fields or getter methods) can be marshalled as well.

But the two ways, i.e. fields and getter-methods, must not conflict with each other. Otherwise you get the exception.

The git command that would be the closest from what you are looking for would by git archive.
See backing up project which uses git: it will include in an archive all files (including submodules if you are using the git-archive-all script)

You can then use that archive anywhere, giving you back only files, no .git directory.

git archive --remote=<repository URL> | tar -t

If you need folders and files just from the first level:

git archive --remote=<repository URL> | tar -t --exclude="*/*"

To list only first-level folders of a remote repo:

git archive --remote=<repository URL> | tar -t --exclude="*/*" | grep "/"

Note: that does not work for GitHub (not supported)

So you would need to clone (shallow to quicken the clone step), and then archive locally:

git clone --depth=1 [email protected]:xxx/yyy.git
cd yyy
git archive --format=tar aTag -o aTag.tar

Another option would be to do a shallow clone (as mentioned below), but locating the .git folder elsewhere.

git --git-dir=/path/to/another/folder.git clone --depth=1 /url/to/repo

The repo folder would include only the file, without .git.

Note: git --git-dir is an option of the command git, not git clone.

Update with Git 2.14.X/2.15 (Q4 2017): it will make sure to avoid adding empty folders.

"git archive", especially when used with pathspec, stored an empty directory in its output, even though Git itself never does so.
This has been fixed.

See commit 4318094 (12 Sep 2017) by René Scharfe (``).

archive: don't add empty directories to archives

While git doesn't track empty directories, git archive can be tricked into putting some into archives.
While that is supported by the object database, it can't be represented in the index and thus it's unlikely to occur in the wild.

As empty directories are not supported by git, they should also not be written into archives.
If an empty directory is really needed then it can be tracked and archived by placing an empty .gitignore file in it.

The scope <scope>provided</scope> gives you an opportunity to tell that the jar would be available at runtime, so do not bundle it. It does not mean that you do not need it at compile time, hence maven would try to download that.

Now I think, the below maven artifact do not exist at all. I tries searching google, but not able to find. Hence you are getting this issue.

Change groupId to <groupId>net.sourceforge.ant4x</groupId> to get the latest jar.

<dependency>
  <groupId>net.sourceforge.ant4x</groupId>
  <artifactId>ant4x</artifactId>
  <version>${net.sourceforge.ant4x-version}</version>
  <scope>provided</scope>
</dependency>

Another solution for this problem is:

1. Run your own maven repo.
2. download the jar
3. Install the jar into the repository.
4. Add a code in your pom.xml something like:

Where http://localhost/repo is your local repo URL:

<repositories>
    <repository>
        <id>wmc-central</id>
        <url>http://localhost/repo</url>
    </repository>
    <-- Other repository config ... -->
</repositories>

Here is a good explanation of your problem with the solution.

1. Download winutils.exe from http://public-repo-1.hortonworks.com/hdp-win-alpha/winutils.exe.

2. SetUp your HADOOP_HOME environment variable on the OS level or programmatically:

   System.setProperty("hadoop.home.dir", "full path to the folder with winutils");

3. Enjoy

You can use HTML5 Websockets to introduce your own push messages. From Wikipedia:

"For the client side, WebSocket was to be implemented in Firefox 4, Google Chrome 4, Opera 11, and Safari 5, as well as the mobile version of Safari in iOS 4.2. Also the BlackBerry Browser in OS7 supports WebSockets."

To do this, you need your own provider server to push the messages to the clients.
If you want to use APN (Apple Push Notification) or C2DM (Cloud to Device Message), you must have a native application which must be downloaded through the online store.

To answer the exact question:

import "github.com/golang/protobuf/ptypes"

Timestamp, _ = ptypes.TimestampProto(time.Now())

You better use array_shift(). That will return the first element of the array, remove it from the array and re-index the array. All in one efficient method.

If you are running Tomcat from Eclipse, it doesn't use the configuration from your actual Tomcat installation. It uses the Tomcat configuration that it created and stored under "Servers" project. If you view your Eclipse workspace, you should see a project called "Servers". Expand that "Servers" project and you will come across server.xml. Open this file and scroll all the way to the bottom, and you should see something like this:-

<Context docBase="abc" path="/abc" reloadable="true" source="org.eclipse.jst.jee.server:abc"/>

Here, you can just change your project context path to something else.

Hope this helps.

You can install the Active Directory snap-in with Powershell on Windows Server 2012 using the following command:

Install-windowsfeature -name AD-Domain-Services –IncludeManagementTools

This helped me when I had problems with the Features screen due to AppFabric and Windows Update errors.

(A==B).all()

test if all values of array (A==B) are True.

Note: maybe you also want to test A and B shape, such as A.shape == B.shape

Special cases and alternatives (from dbaupp's answer and yoavram's comment)

It should be noted that:

• this solution can have a strange behavior in a particular case: if either A or B is empty and the other one contains a single element, then it return True. For some reason, the comparison A==B returns an empty array, for which the all operator returns True.
• Another risk is if A and B don't have the same shape and aren't broadcastable, then this approach will raise an error.

In conclusion, if you have a doubt about A and B shape or simply want to be safe: use one of the specialized functions:

np.array_equal(A,B)  # test if same shape, same elements values
np.array_equiv(A,B)  # test if broadcastable shape, same elements values
np.allclose(A,B,...) # test if same shape, elements have close enough values

You can do it

forfiles /M myfile.txt /C "cmd /c echo @fdate @ftime"

"use strict";

Basically it enables the strict mode.

Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.

As per your comments you are telling some differences will be there. But it's your assumption. The Node.js code is nothing but your JavaScript code. All Node.js code are interpreted by the V8 JavaScript engine. The V8 JavaScript Engine is an open source JavaScript engine developed by Google for Chrome web browser.

So, there will be no major difference how "use strict"; is interpreted by the Chrome browser and Node.js.

Please read what is strict mode in JavaScript.

For more information:

1. Strict mode
2. ECMAScript 5 Strict mode support in browsers
3. Strict mode is coming to town
4. Compatibility table for strict mode
5. Stack Overflow questions: what does 'use strict' do in JavaScript & what is the reasoning behind it

ECMAScript 6 Code & strict mode. Following is brief from the specification:

10.2.1 Strict Mode Code

An ECMAScript Script syntactic unit may be processed using either unrestricted or strict mode syntax and semantics. Code is interpreted as strict mode code in the following situations:

• Global code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive (see 14.1.1).
• Module code is always strict mode code.
• All parts of a ClassDeclaration or a ClassExpression are strict mode code.
• Eval code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive or if the call to eval is a direct eval (see 12.3.4.1) that is contained in strict mode code.
• Function code is strict mode code if the associated FunctionDeclaration, FunctionExpression, GeneratorDeclaration, GeneratorExpression, MethodDefinition, or ArrowFunction is contained in strict mode code or if the code that produces the value of the function’s [[ECMAScriptCode]] internal slot begins with a Directive Prologue that contains a Use Strict Directive.
• Function code that is supplied as the arguments to the built-in Function and Generator constructors is strict mode code if the last argument is a String that when processed is a FunctionBody that begins with a Directive Prologue that contains a Use Strict Directive.

Additionally if you are lost on what features are supported by your current version of Node.js, this node.green can help you (leverages from the same data as kangax).

As Toan suggests, a simple hack would be to just select the rows first, and then select the columns over that.

>>> a[[0,1,3], :]            # Returns the rows you want
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [12, 13, 14, 15]])
>>> a[[0,1,3], :][:, [0,2]]  # Selects the columns you want as well
array([[ 0,  2],
       [ 4,  6],
       [12, 14]])

[Edit] The built-in method: np.ix_

I recently discovered that numpy gives you an in-built one-liner to doing exactly what @Jaime suggested, but without having to use broadcasting syntax (which suffers from lack of readability). From the docs:

Using ix_ one can quickly construct index arrays that will index the cross product. a[np.ix_([1,3],[2,5])] returns the array [[a[1,2] a[1,5]], [a[3,2] a[3,5]]].

So you use it like this:

>>> a = np.arange(20).reshape((5,4))
>>> a[np.ix_([0,1,3], [0,2])]
array([[ 0,  2],
       [ 4,  6],
       [12, 14]])

And the way it works is that it takes care of aligning arrays the way Jaime suggested, so that broadcasting happens properly:

>>> np.ix_([0,1,3], [0,2])
(array([[0],
        [1],
        [3]]), array([[0, 2]]))

Also, as MikeC says in a comment, np.ix_ has the advantage of returning a view, which my first (pre-edit) answer did not. This means you can now assign to the indexed array:

>>> a[np.ix_([0,1,3], [0,2])] = -1
>>> a    
array([[-1,  1, -1,  3],
       [-1,  5, -1,  7],
       [ 8,  9, 10, 11],
       [-1, 13, -1, 15],
       [16, 17, 18, 19]])

You can also add this to your form:

<form ... target="_blank">

Either u dont have permission to that schema/table OR table does exist. Mostly this issue occurred if you are using other schema tables in your stored procedures. Eg. If you are running Stored Procedure from user/schema ABC and in the same PL/SQL there are tables which is from user/schema XYZ. In this case ABC should have GRANT i.e. privileges of XYZ tables

Grant All On To ABC;

Select * From Dba_Tab_Privs Where Owner = 'XYZ'and Table_Name = <Table_Name>;

ASP.NET Web API is a framework that makes it easy to build HTTP services that reach a broad range of clients, including browsers and mobile devices. ASP.NET Web API is an ideal platform for building RESTful applications on the .NET Framework.

REST

RESTs sweet spot is when you are exposing a public API over the internet to handle CRUD operations on data. REST is focused on accessing named resources through a single consistent interface.

SOAP

SOAP brings it’s own protocol and focuses on exposing pieces of application logic (not data) as services. SOAP exposes operations. SOAP is focused on accessing named operations, each implement some business logic through different interfaces.

Though SOAP is commonly referred to as “web services” this is a misnomer. SOAP has very little if anything to do with the Web. REST provides true “Web services” based on URIs and HTTP.

Reference: http://spf13.com/post/soap-vs-rest

And finally: What they could be referring to is REST vs. RPC See this: http://encosia.com/rest-vs-rpc-in-asp-net-web-api-who-cares-it-does-both/

None of answered method solve the problem which log4j.properties file is not found for non-maven jsf web project in NetBeans. So the answer is:

1. Create a folder named resources in project root folder (outermost folder).
2. Right click project in projects explorer in left menu, select properties.
3. Open Sources in Categories, add that folder in Source Package Folders.
4. Open Run in Categories and add this to VM options: Dlog4j.configuration=resources/log4j.properties
5. Click Ok, build and deploy project as you like, that's it.

I wrote special pattern in log4j file to check whether log4j is used my file:

# Root Logger Option
log4j.rootLogger=INFO, console

# Redirect Log Messages To Console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.Target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.ConversionPattern=%-5p | %d{yyyy-MM-dd HH:mm:ss} | [%t] %C{2} xxxx (%F:%L) - %m%n

I checked it because if you use BasicConfigurator.configure(); in your code in log4j use predefined pattern.

The other answers are correct (with a caveat*). I add this answer simply to show an example usage:

- (void)getYourAffairsInOrder
{
    NSDate* methodStart = [NSDate date];  // Capture start time.

    // … Do some work …

    NSLog(@"DEBUG Method %s ran. Elapsed: %f seconds.", __func__, -([methodStart timeIntervalSinceNow]));  // Calculate and report elapsed time.
}

On the debugger console, you see something like this:

DEBUG Method '-[XMAppDelegate getYourAffairsInOrder]' ran. Elapsed: 0.033827 seconds.

*Caveat: As others mentioned, use NSDate to calculate elapsed time only for casual purposes. One such purpose might be common testing, crude profiling, where you just want a rough idea of how long a method is taking.

The risk is that the device's clock's current time setting could change at any moment because of network clock syncing. So NSDate time could jump forward or backward at any moment.

After searching a lot and trying to install and reinstall Python, i found the solution was very simple

use the following for windows

python -m pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.0-py3-none-any.whl

change to following on mac

python3 -m pip install --upgrade https://storage.googleapis.com/tensorflow/mac/cpu/tensorflow-0.12.0-py3-none-any.whl

for Anaconda use corresponding conda

Late to the game, but here's a really handy function that is super simple to use, allows you to pass as many arguments as you like, of any type, and will display the object contents in the browser console window as though you called console.log from JavaScript - but from PHP

Note, you can use tags as well by passing 'TAG-YourTag' and it will be applied until another tag is read, for example, 'TAG-YourNextTag'

/*
*   Brief:          Print to console.log() from PHP
*   Description:    Print as many strings,arrays, objects, and other data types to console.log from PHP.
*                   To use, just call consoleLog($data1, $data2, ... $dataN) and each dataI will be sent to console.log - note that
*                   you can pass as many data as you want an this will still work.
*
*                   This is very powerful as it shows the entire contents of objects and arrays that can be read inside of the browser console log.
*                   
*                   A tag can be set by passing a string that has the prefix TAG- as one of the arguments. Everytime a string with the TAG- prefix is
*                   detected, the tag is updated. This allows you to pass a tag that is applied to all data until it reaches another tag, which can then
*                   be applied to all data after it.
*
*                   Example:
*                   consoleLog('TAG-FirstTag',$data,$data2,'TAG-SecTag,$data3); 
*                   Result:
*                       FirstTag '...data...'
*                       FirstTag '...data2...'
*                       SecTag   '...data3...' 
*/
function consoleLog(){
    if(func_num_args() == 0){
        return;
    }

    $tag = '';
    for ($i = 0; $i < func_num_args(); $i++) {
        $arg = func_get_arg($i);
        if(!empty($arg)){       
            if(is_string($arg)&& strtolower(substr($arg,0,4)) === 'tag-'){
                $tag = substr($arg,4);
            }else{      
                $arg = json_encode($arg, JSON_HEX_TAG | JSON_HEX_AMP );
                echo "<script>console.log('".$tag." ".$arg."');</script>";
            }       
        }
    }
}

NOTE: func_num_args() and func_num_args() are php functions for reading a dynamic number of input args, and allow this function to have infinitely many console.log requests from one function call

Slight correction to dabest1's answer above. Specify the timezone as UTC, not GMT:

$ date -d '1970-01-01 1416275583 sec GMT'
Tue Nov 18 00:53:03 GMT 2014
$ date -d '1970-01-01 1416275583 sec UTC'
Tue Nov 18 01:53:03 GMT 2014

The second one is correct. I think the reason is that in the UK, daylight saving was in force continually from 1968 to 1971.

It means "not equal to" (as in, the values in cells E37-N37 are not equal to "", or in other words, they are not empty.)

I have been toying with this idea too, but I was trying to achieve a slightly different behavior. My idea was to make a list which inherits itself, thus creating a data structure that by nature allows you to embed lists within lists within lists within lists...infinitely!

Implementation

//InfiniteList<T> is a list of itself...
public class InfiniteList<T> : List<InfiniteList<T>>
{
    //This is necessary to allow your lists to store values (of type T).
    public T Value { set; get; }
}

T is a generic type parameter. It is there to ensure type safety in your class. When you create an instance of InfiniteList, you replace T with the type you want your list to be populated with, or in this instance, the type of the Value property.

Example

//The InfiniteList.Value property will be of type string
InfiniteList<string> list = new InfiniteList<string>();

A "working" example of this, where T is in itself, a List of type string!

//Create an instance of InfiniteList where T is List<string>
InfiniteList<List<string>> list = new InfiniteList<List<string>>();

//Add a new instance of InfiniteList<List<string>> to "list" instance.
list.Add(new InfiniteList<List<string>>());

//access the first element of "list". Access the Value property, and add a new string to it.
list[0].Value.Add("Hello World");

I'd suggest doing something similar to:

function show_sub(cat) {
    if (!cat) {
        return false;
    }
    else if (document.getElementById(cat)) {
        var parent = document.getElementById(cat),
            sub = parent.getElementsByClassName('sub');
        if (sub[0].style.display == 'inline'){
            sub[0].style.display = 'none';
        }
        else {
            sub[0].style.display = 'inline';
        }
    }
}

document.getElementById('cat').onclick = function(){
    show_sub(this.id);
};????

JS Fiddle demo.

Though the above relies on the use of a class rather than a name attribute equal to sub.

As to why your original version "didn't work" (not, I must add, a particularly useful description of the problem), all I can suggest is that, in Chromium, the JavaScript console reported that:

Uncaught TypeError: Object # has no method 'getElementsByName'.

One approach to working around the older-IE family's limitations is to use a custom function to emulate getElementsByClassName(), albeit crudely:

function eBCN(elem,classN){
    if (!elem || !classN){
        return false;
    }
    else {
        var children = elem.childNodes;
        for (var i=0,len=children.length;i<len;i++){
            if (children[i].nodeType == 1
                &&
                children[i].className == classN){
                    var sub = children[i];
            }
        }
        return sub;
    }
}

function show_sub(cat) {
    if (!cat) {
        return false;
    }
    else if (document.getElementById(cat)) {
        var parent = document.getElementById(cat),
            sub = eBCN(parent,'sub');
        if (sub.style.display == 'inline'){
            sub.style.display = 'none';

I think you have putted e.preventDefault(); before ajax call that's why its prevent calling of that function and your Ajax call will not call.

So try to remove that e.prevent Default() before Ajax call and add it to the after Ajax call.

public function index() {

    $user = $this->session->userdata("username");
    $file_path = "./images/" . $user . '/';

    if (isset($_FILES['multipleUpload'])) {

        if (!is_dir('images/' . $user)) {
            mkdir('./images/' . $user, 0777, TRUE);
        }

        $files = $_FILES;
        $cpt = count($_FILES ['multipleUpload'] ['name']);

        for ($i = 0; $i < $cpt; $i ++) {

            $name = time().$files ['multipleUpload'] ['name'] [$i];
            $_FILES ['multipleUpload'] ['name'] = $name;
            $_FILES ['multipleUpload'] ['type'] = $files ['multipleUpload'] ['type'] [$i];
            $_FILES ['multipleUpload'] ['tmp_name'] = $files ['multipleUpload'] ['tmp_name'] [$i];
            $_FILES ['multipleUpload'] ['error'] = $files ['multipleUpload'] ['error'] [$i];
            $_FILES ['multipleUpload'] ['size'] = $files ['multipleUpload'] ['size'] [$i];

            $this->upload->initialize($this->set_upload_options($file_path));
            if(!($this->upload->do_upload('multipleUpload')) || $files ['multipleUpload'] ['error'] [$i] !=0)
            {
                print_r($this->upload->display_errors());
            }
            else
            {
                $this->load->model('uploadModel','um');
                $this->um->insertRecord($user,$name);
            }
        }
    } else {
        $this->load->view('uploadForm');
    }
}

public function set_upload_options($file_path) {
    // upload an image options
    $config = array();
    $config ['upload_path'] = $file_path;

    return $config;
}

Short answer: final helps a tiny bit but... use defensive programming on the client side instead.

Indeed, the problem with final is that it only enforces the reference is unchanged, gleefully allowing the referenced object members to be mutated, unbeknownst to the caller. Hence the best practice in this regard is defensive programming on the caller side, creating deeply immutable instances or deep copies of objects that are in danger of being mugged by unscrupulous APIs.

Try using this instead:

var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();

It's bit hard to navigate Google's api but here is the relevant documentation.

One thing I had trouble finding was how to go in the other direction. From coordinates to an address. Here is the code I neded upp using. Please not that I also use jquery.

$.each(results[0].address_components, function(){
    $("#CreateDialog").find('input[name="'+ this.types+'"]').attr('value', this.long_name);
});

What I'm doing is to loop through all the returned address_components and test if their types match any input element names I have in a form. And if they do I set the value of the element to the address_components value.
If you're only interrested in the whole formated address then you can follow Google's example

Can you show code which you use for setting date object? Anyway< you can use this code for intialisation of date:

new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").parse("2011-01-01 00:00:00")

In your case it should suffice to just add another hidden field to your form dynamically.

var input = $("<input>").attr("type", "hidden").val("Bla");
$('#form').append($(input));

It turns out that a FTP download call using winscp as last thing to do in the batch caused the problem. After inserting the echo command it works fine. Guess the problems source could be the winscp.exe which do not correctly report the end of the current task to the OS.

del "C:\_ftpcrawler\Account Export.csv" /S /Q

"C:\Program Files (x86)\WinSCP\WinSCP.exe" /console /script="C:\_isource\scripte\data.txt"

Windows dll error 126 can have many root causes. The most useful methods I have found to debug this are:

1. Use dependency walker to look for any obvious problems (which you have already done)
2. Use the sysinternals utility Process Monitor http://technet.microsoft.com/en-us/sysinternals/bb896645 from Microsoft to trace all file access while your dll is trying to load. With this utility, you will see everything that that dll is trying to pull in and usually the problem can be determined from there.

Syntax: (Triple dot ... ) --> Means we can add zero or more objects pass in an arguments or pass an array of type object.

public static void main(String[] args){}
public static void main(String... args){}

Definition: 1) The Object ... argument is just a reference to an array of Objects.

2) ('String []' or String ... ) It can able to handle any number of string objects. Internally it uses an array of reference type object.

i.e. Suppose we pass an Object array to the ... argument - will the resultant argument value be a two-dimensional array - because an Object[] is itself an Object:

3) If you want to call the method with a single argument and it happens to be an array, you have to explicitly wrap it in

another. method(new Object[]{array}); 
OR 
method((Object)array), which will auto-wrap.

Application: It majorly used when the number of arguments is dynamic(number of arguments know at runtime) and in overriding. General rule - In the method we can pass any types and any number of arguments. We can not add object(...) arguments before any specific arguments. i.e.

void m1(String ..., String s) this is a wrong approach give syntax error.
void m1(String s, String ...); This is a right approach. Must always give last order prefernces.   

If you are sending anything other than simple strings I would recommend using a POST with an appropriate request body, or passing the entire list as an appropriately encoded JSON string. However, with simple strings you just need to append each value to the request URL appropriately and Jersey will deserialize it for you. So given the following example endpoint:

@Path("/service/echo") public class MyServiceImpl {
    public MyServiceImpl() {
        super();
    }

    @GET
    @Path("/withlist")
    @Produces(MediaType.TEXT_PLAIN)
    public Response echoInputList(@QueryParam("list") final List<String> inputList) {
        return Response.ok(inputList).build();
    }
}

Your client would send a request corresponding to:

GET http://example.com/services/echo?list=Hello&list=Stay&list=Goodbye

Which would result in inputList being deserialized to contain the values 'Hello', 'Stay' and 'Goodbye'

CABForum Baseline Requirements

I see no one has mentioned the section in the Baseline Requirements yet. I feel they are important.

Q: SSL - How do Common Names (CN) and Subject Alternative Names (SAN) work together?
A: Not at all. If there are SANs, then CN can be ignored. -- At least if the software that does the checking adheres very strictly to the CABForum's Baseline Requirements.

(So this means I can't answer the "Edit" to your question. Only the original question.)

CABForum Baseline Requirements, v. 1.2.5 (as of 2 April 2015), page 9-10:

9.2.2 Subject Distinguished Name Fields
a. Subject Common Name Field
Certificate Field: subject:commonName (OID 2.5.4.3)
Required/Optional: Deprecated (Discouraged, but not prohibited)
Contents: If present, this field MUST contain a single IP address or Fully-Qualified Domain Name that is one of the values contained in the Certificate’s subjectAltName extension (see Section 9.2.1).

EDIT: Links from @Bruno's comment

RFC 2818: HTTP Over TLS, 2000, Section 3.1: Server Identity:

If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.

RFC 6125: Representation and Verification of Domain-Based Application Service Identity within Internet Public Key Infrastructure Using X.509 (PKIX) Certificates in the Context of Transport Layer Security (TLS), 2011, Section 6.4.4: Checking of Common Names:

[...] if and only if the presented identifiers do not include a DNS-ID, SRV-ID, URI-ID, or any application-specific identifier types supported by the client, then the client MAY as a last resort check for a string whose form matches that of a fully qualified DNS domain name in a Common Name field of the subject field (i.e., a CN-ID).

Each answer is missing some points, so here is my solution:

$("#input").on("input", function(e) {_x000D_
  var input = $(this);_x000D_
  var val = input.val();_x000D_
_x000D_
  if (input.data("lastval") != val) {_x000D_
    input.data("lastval", val);_x000D_
_x000D_
    //your change action goes here _x000D_
    console.log(val);_x000D_
  }_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="text" id="input">_x000D_
<p>Try to drag the letters and copy paste</p>

The Input Event fires on Keyboard input, Mouse Drag, Autofill and Copy-Paste tested on Chrome and Firefox. Checking for previous value makes it detect real changes, which means not firing when pasting the same thing or typing the same character or etc.

Working example: http://jsfiddle.net/g6pcp/473/

update:

And if you like to run your change function only when user finishes typing and prevent firing the change action several times, you could try this:

var timerid;_x000D_
$("#input").on("input", function(e) {_x000D_
  var value = $(this).val();_x000D_
  if ($(this).data("lastval") != value) {_x000D_
_x000D_
    $(this).data("lastval", value);_x000D_
    clearTimeout(timerid);_x000D_
_x000D_
    timerid = setTimeout(function() {_x000D_
      //your change action goes here _x000D_
      console.log(value);_x000D_
    }, 500);_x000D_
  };_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input type="text" id="input">

If user starts typing (e.g. "foobar") this code prevents your change action to run for every letter user types and and only runs when user stops typing, This is good specially for when you send the input to the server (e.g. search inputs), that way server does only one search for foobar and not six searches for f and then fo and then foo and foob and so on.

To expand upon nosklo's explanation:

a = {}
b = ['some', 'list']
a[b] = 'some' # this won't work
a[tuple(b)] = 'some' # this will, same as a['some', 'list']

Fastest approach is the traditional for loop. Here is a more comprehensive performance comparison.

The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.

If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.

A possible solution from git config:

git config --global mergetool.keepBackup false

After performing a merge, the original file with conflict markers can be saved as a file with a .orig extension.
If this variable is set to false then this file is not preserved.
Defaults to true (i.e. keep the backup files).

The alternative being not adding or ignoring those files, as suggested in this gitguru article,

git mergetool saves the merge-conflict version of the file with a “.orig” suffix.
Make sure to delete it before adding and committing the merge or add *.orig to your .gitignore.

Berik suggests in the comments to use:

find . -name \*.orig 
find . -name \*.orig -delete

Charles Bailey advises in his answer to be aware of internal diff tool settings which could also generate those backup files, no matter what git settings are.

• kdiff3 has its own settings (see "Directory merge" in its manual).
• other tools like WinMerge can have their own backup file extension (WinMerge: .bak, as mentioned in its manual).

So you need to reset those settings as well.

scipy.stats has methods trim1() and trimboth() to cut the outliers out in a single row, according to the ranking and an introduced percentage of removed values.

Modify to suit your specifics, or make more generic as needed:

Private Sub CopyItOver()
  Set NewBook = Workbooks.Add
  Workbooks("Whatever.xlsx").Worksheets("output").Range("A1:K10").Copy
  NewBook.Worksheets("Sheet1").Range("A1").PasteSpecial (xlPasteValues)
  NewBook.SaveAs FileName:=NewBook.Worksheets("Sheet1").Range("E3").Value
End Sub

I'd recommend the Range object's AutoFill method for this:

rngSource.AutoFill Destination:=rngDest

Specify the Source range that contains the values or formulas you want to fill down, and the Destination range as the whole range that you want the cells filled to. The Destination range must include the Source range. You can fill across as well as down.

It works exactly the same way as it would if you manually "dragged" the cells at the corner with the mouse; absolute and relative formulas work as expected.

Here's an example:

'Set some example values'
Range("A1").Value = "1"
Range("B1").Formula = "=NOW()"
Range("C1").Formula = "=B1+A1"

'AutoFill the values / formulas to row 20'
Range("A1:C1").AutoFill Destination:=Range("A1:C20")

Hope this helps.

The cleanest way I found to do this is create a child of 'ThemeOverlay.AppCompat.Dark.ActionBar'. In the example, I set the Toolbar's background color to RED and text's color to BLUE.

<style name="MyToolbar" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:background">#FF0000</item>
    <item name="android:textColorPrimary">#0000FF</item>
</style>

You can then apply your theme to the toolbar:

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    app:theme="@style/MyToolbar"
    android:minHeight="?attr/actionBarSize"/>

If you're using node later than 7.6 and you don't like the callback style, you can also use node-util's promisify function with async / await to get shell commands which read cleanly. Here's an example of the accepted answer, using this technique:

const { promisify } = require('util');
const exec = promisify(require('child_process').exec)

module.exports.getGitUser = async function getGitUser () {
  const name = await exec('git config --global user.name')
  const email = await exec('git config --global user.email')
  return { name, email }
};

This also has the added benefit of returning a rejected promise on failed commands, which can be handled with try / catch inside the async code.

In Python:

# as Peter van der Wal's answer
re.split(r'\r\n|\r|\n', text, flags=re.M) 

or more rigorous:

# https://docs.python.org/3/library/stdtypes.html#str.splitlines
str.splitlines()

Yaml and Json are the simplest and most commonly used file formats to store settings/config. PyYaml can be used to parse yaml. Json is already part of python from 2.5. Yaml is a superset of Json. Json will solve most uses cases except multi line strings where escaping is required. Yaml takes care of these cases too.

>>> import json
>>> config = {'handler' : 'adminhandler.py', 'timeoutsec' : 5 }
>>> json.dump(config, open('/tmp/config.json', 'w'))
>>> json.load(open('/tmp/config.json'))   
{u'handler': u'adminhandler.py', u'timeoutsec': 5}

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}

And here is a plunker demonstrating what it sounds like you're trying to do: https://plnkr.co/edit/OUoD5J1lfO6bIeME9N0F?p=preview

Under FF you can use the XMLSerializer object to serialize XML into a string. IE gives you an xml property of a node. So you can do the following:

function xml2string(node) {
   if (typeof(XMLSerializer) !== 'undefined') {
      var serializer = new XMLSerializer();
      return serializer.serializeToString(node);
   } else if (node.xml) {
      return node.xml;
   }
}

Got the solution and it's working fine. Set the environment variables as:

• CATALINA_HOME=C:\Program Files\Java\apache-tomcat-7.0.59\apache-tomcat-7.0.59 (path where your Apache Tomcat is)
• JAVA_HOME=C:\Program Files\Java\jdk1.8.0_25; (path where your JDK is)
• JRE_Home=C:\Program Files\Java\jre1.8.0_25; (path where your JRE is)
• CLASSPATH=%JAVA_HOME%\bin;%JRE_HOME%\bin;%CATALINA_HOME%\lib

it depends on what role this foreign key plays in your relation.

1. if this foreign key is also a key attribute in your relation, then it can't be NULL
2. if this foreign key is a normal attribute in your relation, then it can be NULL.

FORFILES /S /D -10 /C "cmd /c IF @isdir == TRUE rd /S /Q @path"

I could not get Blorgbeard's suggestion to work, but I was able to get it to work with RMDIR instead of RD:

FORFILES /p N:\test /S /D -10 /C "cmd /c IF @isdir == TRUE RMDIR /S /Q @path"

Since RMDIR won't delete folders that aren't empty so I also ended up using this code to delete the files that were over 10 days and then the folders that were over 10 days old.

FOR /d %%K in ("n:\test*") DO (

FOR /d %%J in ("%%K*") DO (

FORFILES /P %%J /S /M . /D -10 /C "cmd /c del @file"

)

)

FORFILES /p N:\test /S /D -10 /C "cmd /c IF @isdir == TRUE RMDIR /S /Q @path"

I used this code to purge out the sub folders in the folders within test (example n:\test\abc\123 would get purged when empty, but n:\test\abc would not get purged

The question is already answered, however when I first saw it I thought of NodeJS Buffer. But it is way slower than the +, so it is likely that nothing can be faster than + in string concetanation.

Tested with the following code:

function a(){
    var s = "hello";
    var p = "world";
    s = s + p;
    return s;
}

function b(){
    var s = new Buffer("hello");
    var p = new Buffer("world");
    s = Buffer.concat([s,p]);
    return s;
}

var times = 100000;

var t1 = new Date();
for( var i = 0; i < times; i++){
    a();
}

var t2 = new Date();
console.log("Normal took: " + (t2-t1) + " ms.");
for ( var i = 0; i < times; i++){
    b();
}

var t3 = new Date();

console.log("Buffer took: " + (t3-t2) + " ms.");

Output:

Normal took: 4 ms.
Buffer took: 458 ms.

One difference is that:

• :map does nvo == normal + (visual + select) + operator pending
• :map! does ic == insert + command-line mode

as stated on help map-modes tables.

So: map does not map to all modes.

To map to all modes you need both :map and :map!.

You may have as many levels of Object hierarchy as you want, as long you declare an Object as being a property of another parent Object. Pay attention to the commas on each level, that's the tricky part. Don't use commas after the last element on each level:

{el1, el2, {el31, el32, el33}, {el41, el42}}

var MainObj = {_x000D_

    prop1: "prop1Obj1",_x000D_

I had an issue implementing the accepted solution pattern where my ModelStateFilter would always return false (and subsequently a 400) for actionContext.ModelState.IsValid for certain model objects:

public class ModelStateFilter : ActionFilterAttribute
{
    public override void OnActionExecuting(HttpActionContext actionContext)
    {
        if (!actionContext.ModelState.IsValid)
        {
            actionContext.Response = new HttpResponseMessage { StatusCode = HttpStatusCode.BadRequest};
        }
    }
}

I only accept JSON, so I implemented a custom model binder class:

public class AddressModelBinder : System.Web.Http.ModelBinding.IModelBinder
{
    public bool BindModel(HttpActionContext actionContext, System.Web.Http.ModelBinding.ModelBindingContext bindingContext)
    {
        var posted = actionContext.Request.Content.ReadAsStringAsync().Result;
        AddressDTO address = JsonConvert.DeserializeObject<AddressDTO>(posted);
        if (address != null)
        {
            // moar val here

            return true;
        }
        return false;
    }
}

Which I register directly after my model via

config.BindParameter(typeof(AddressDTO), new AddressModelBinder());

Try this:

 git fetch --all
 git reset --hard origin/master

Explanation:

git fetch downloads the latest from remote without trying to merge or rebase anything.

Please let me know if you have any questions!

See, why this way that you are doing is not working. First, you are trying to get integer from a Row Type, the output of your collect is like this:

>>> mvv_list = mvv_count_df.select('mvv').collect()
>>> mvv_list[0]
Out: Row(mvv=1)

If you take something like this:

>>> firstvalue = mvv_list[0].mvv
Out: 1

You will get the mvv value. If you want all the information of the array you can take something like this:

>>> mvv_array = [int(row.mvv) for row in mvv_list.collect()]
>>> mvv_array
Out: [1,2,3,4]

But if you try the same for the other column, you get:

>>> mvv_count = [int(row.count) for row in mvv_list.collect()]
Out: TypeError: int() argument must be a string or a number, not 'builtin_function_or_method'

This happens because count is a built-in method. And the column has the same name as count. A workaround to do this is change the column name of count to _count:

>>> mvv_list = mvv_list.selectExpr("mvv as mvv", "count as _count")
>>> mvv_count = [int(row._count) for row in mvv_list.collect()]

But this workaround is not needed, as you can access the column using the dictionary syntax:

>>> mvv_array = [int(row['mvv']) for row in mvv_list.collect()]
>>> mvv_count = [int(row['count']) for row in mvv_list.collect()]

And it will finally work!

One way is to replace the double quotes in the HTML with single quotes but using double quotes has become the standard convention for attribute values in HTML.

The better option is to escape the double quotes in json and other characters that need to be escaped.

You can get some more details about escaping here: Where can I find a list of escape characters required for my JSON ajax return type?

multipart/form-data encoded requests are indeed not by default supported by the Servlet API prior to version 3.0. The Servlet API parses the parameters by default using application/x-www-form-urlencoded encoding. When using a different encoding, the request.getParameter() calls will all return null. When you're already on Servlet 3.0 (Glassfish 3, Tomcat 7, etc), then you can use HttpServletRequest#getParts() instead. Also see this blog for extended examples.

Prior to Servlet 3.0, a de facto standard to parse multipart/form-data requests would be using Apache Commons FileUpload. Just carefully read its User Guide and Frequently Asked Questions sections to learn how to use it. I've posted an answer with a code example before here (it also contains an example targeting Servlet 3.0).

For MacOS users:

Just do this and easily it will solve your problem:

brew install cocoapods

It's really hard to tell, but one of the 9001 ads on the page may be clobbering the $ object.

jQuery provides the global jQuery object (which is present on your page). You can do the following to "get" $ back:

jQuery(document).ready(function ($) {
    // Your code here
});

If you think you're having jQuery problems, please use the debug (non-production) versions of the library.

Also, it's probably not best to be editing a live site like that ...

Try to update your compiler, I'm using GCC 4.7 on Windows 7 Starter x86 with MinGW and it compiles fine with the same options both in C99 and C11.

It means that:

• public - it can be called from anywhere
• static - it doesn't have any object state, so you can call it without instantiating an object
• void - it doesn't return anything

You'd think that the lack of a return means it isn't doing much, but it might be saving things in the database, for example.

echo "{$test}y";

You can use braces to remove ambiguity when interpolating variables directly in strings.

Also, this doesn't work with single quotes. So:

echo '{$test}y';

will output

{$test}y

When you do self.button = Button(...).grid(...), what gets assigned to self.button is the result of the grid() command, not a reference to the Button object created.

You need to assign your self.button variable before packing/griding it. It should look something like this:

self.button = Button(self,text="Click Me",command=self.color_change,bg="blue")
self.button.grid(row = 2, column = 2, sticky = W)

First just to answer a comment in the accepts answer.

"What does bind do? What if I have an interface and an implementation?"

It simply reads bind( implementation ).to( contract ). You can alternative chain .in( scope ). Default scope of PerLookup. So if you want a singleton, you can

bind( implementation ).to( contract ).in( Singleton.class );

There's also a RequestScoped available

Also, instead of bind(Class).to(Class), you can also bind(Instance).to(Class), which will be automatically be a singleton.

Adding to the accepted answer

For those trying to figure out how to register your AbstractBinder implementation in your web.xml (i.e. you're not using a ResourceConfig), it seems the binder won't be discovered through package scanning, i.e.

<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
    <param-name>jersey.config.server.provider.packages</param-name>
    <param-value>
        your.packages.to.scan
    </param-value>
</init-param>

Or this either

<init-param>
    <param-name>jersey.config.server.provider.classnames</param-name>
    <param-value>
        com.foo.YourBinderImpl
    </param-value>
</init-param>

To get it to work, I had to implement a Feature:

import javax.ws.rs.core.Feature;
import javax.ws.rs.core.FeatureContext;
import javax.ws.rs.ext.Provider;

@Provider
public class Hk2Feature implements Feature {

    @Override
    public boolean configure(FeatureContext context) {
        context.register(new AppBinder());
        return true;
    }
}

The @Provider annotation should allow the Feature to be picked up by the package scanning. Or without package scanning, you can explicitly register the Feature in the web.xml

<servlet>
    <servlet-name>Jersey Web Application</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.classnames</param-name>
        <param-value>
            com.foo.Hk2Feature
        </param-value>
    </init-param>
    ...
    <load-on-startup>1</load-on-startup>
</servlet>

UPDATE

Factories

Aside from the basic binding in the accepted answer, you also have factories, where you can have more complex creation logic, and also have access to request context information. For example

public class MyServiceFactory implements Factory<MyService> {
    @Context
    private HttpHeaders headers;

    @Override
    public MyService provide() {
        return new MyService(headers.getHeaderString("X-Header"));
    }

    @Override
    public void dispose(MyService service) { /* noop */ }
}

register(new AbstractBinder() {
    @Override
    public void configure() {
        bindFactory(MyServiceFactory.class).to(MyService.class)
                .in(RequestScoped.class);
    }
});

Then you can inject MyService into your resource class.

TextView has an android:drawablePadding property which should do the trick:

android:drawablePadding

The padding between the drawables and the text.

Must be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), mm (millimeters).

This may also be a reference to a resource (in the form "@[package:]type:name") or theme attribute (in the form "?[package:][type:]name") containing a value of this type.

This corresponds to the global attribute resource symbol drawablePadding.

and without the LINQ:

string[] ss = {"1","1","1"};

var myList = new List<string>();
var duplicates = new List<string>();

foreach (var s in ss)
{
   if (!myList.Contains(s))
      myList.Add(s);
   else
      duplicates.Add(s);
}

// show list without duplicates 
foreach (var s in myList)
   Console.WriteLine(s);

// show duplicates list
foreach (var s in duplicates)
   Console.WriteLine(s);

Was just trying to work this out myself, and the solution I came up with was:

<meta name="viewport" content="initial-scale = 1.0,maximum-scale = 1.0" />

This seems to lock the device into 1.0 scale regardless of it's orientation. As a side effect, it does however completely disable user scaling (pinch zooming, etc).

1-Delete the migration file. 2-connect to your database and drop the table created by the migration. 3-recreate the file of the migration with the the right sql.

You normally use a tool like pip to install wheels. Leave it to the tool to discover and download the file if this is for a project hosted on PyPI.

For this to work, you do need to install the wheel package:

pip install wheel

You can then tell pip to install the project (and it'll download the wheel if available), or the wheel file directly:

pip install project_name  # discover, download and install
pip install wheel_file.whl  # directly install the wheel

The wheel module, once installed, also is runnable from the command line, you can use this to install already-downloaded wheels:

python -m wheel install wheel_file.whl

Also see the wheel project documentation.

I had this same issue but my fix was much more basic:

If the LogCat panel is empty in Eclipse the emulator doesn't have the focus. Go to the DDMS perspective and try clicking on the 'emulator' entry in the Devices panel (top-left screen).

If this is happening to you with Android 6 and compile target >= 23, don't forget that we are now using runtime permissions. So giving permissions in the manifest is not enough anymore.

You can also produce array by using file:

$array = file('/path/to/text.txt');

If you don't want to show controls then try this code

<audio  autoplay>
 <source src="song.ogg"  type="audio/ogg">
Your browser does not support the audio element.
</audio>

To change the font size of the <input /> tag in HTML, use this:

<input style="font-size:20px" type="text" value="" />

It will create a text input box and the text inside the text box will be 20 pixels.

To disable a single rule for the rest of the file below:

/* eslint no-undef: "off"*/
const uploadData = new FormData();

Make a service call like this:

public async void SaveActivationCode(ActivationCodes objAC)
{
    var client = new HttpClient();
    client.BaseAddress = new Uri(baseAddress);
    HttpResponseMessage response = await client.PutAsJsonAsync(serviceAddress + "/SaveActivationCode" + "?apiKey=445-65-1216", objAC);
} 

And Service method like this:

public HttpResponseMessage PutSaveActivationCode(ActivationCodes objAC)
{
}

PutAsJsonAsync takes care of Serialization and deserialization over the network

The best way to achieve this is to turn off default line separators, subclass UITableViewCell and add a custom line separator as a subview of the contentView - see below a custom cell that is used to present an object of type SNStock that has two string properties, ticker and name:

import UIKit

private let kSNStockCellCellHeight: CGFloat = 65.0
private let kSNStockCellCellLineSeparatorHorizontalPaddingRatio: CGFloat = 0.03
private let kSNStockCellCellLineSeparatorBackgroundColorAlpha: CGFloat = 0.3
private let kSNStockCellCellLineSeparatorHeight: CGFloat = 1

class SNStockCell: UITableViewCell {

  private let primaryTextColor: UIColor
  private let secondaryTextColor: UIColor

  private let customLineSeparatorView: UIView

  var showsCustomLineSeparator: Bool {
    get {
      return !customLineSeparatorView.hidden
    }
    set(showsCustomLineSeparator) {
      customLineSeparatorView.hidden = !showsCustomLineSeparator
    }
  }

  var customLineSeparatorColor: UIColor? {
   get {
     return customLineSeparatorView.backgroundColor
   }
   set(customLineSeparatorColor) {
     customLineSeparatorView.backgroundColor = customLineSeparatorColor?.colorWithAlphaComponent(kSNStockCellCellLineSeparatorBackgroundColorAlpha)
    }
  }

  required init(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
  }

  init(reuseIdentifier: String, primaryTextColor: UIColor, secondaryTextColor: UIColor) {
    self.primaryTextColor = primaryTextColor
    self.secondaryTextColor = secondaryTextColor
    self.customLineSeparatorView = UIView(frame:CGRectZero)
    super.init(style: UITableViewCellStyle.Subtitle, reuseIdentifier:reuseIdentifier)
    selectionStyle = UITableViewCellSelectionStyle.None
    backgroundColor = UIColor.clearColor()

    contentView.addSubview(customLineSeparatorView)
    customLineSeparatorView.hidden = true
  }

  override func prepareForReuse() {
    super.prepareForReuse()
    self.showsCustomLineSeparator = false
  }

  // MARK: Layout

  override func layoutSubviews() {
    super.layoutSubviews()
    layoutCustomLineSeparator()
  }

  private func layoutCustomLineSeparator() {
    let horizontalPadding: CGFloat = bounds.width * kSNStockCellCellLineSeparatorHorizontalPaddingRatio
    let lineSeparatorWidth: CGFloat = bounds.width - horizontalPadding * 2;
    customLineSeparatorView.frame = CGRectMake(horizontalPadding,
      kSNStockCellCellHeight - kSNStockCellCellLineSeparatorHeight,
      lineSeparatorWidth,
      kSNStockCellCellLineSeparatorHeight)
  }

  // MARK: Public Class API

  class func cellHeight() -> CGFloat {
    return kSNStockCellCellHeight
  }

  // MARK: Public API

  func configureWithStock(stock: SNStock) {
    textLabel!.text = stock.ticker as String
    textLabel!.textColor = primaryTextColor
    detailTextLabel!.text = stock.name as String
    detailTextLabel!.textColor = secondaryTextColor
    setNeedsLayout()
  } 
}

To disable the default line separator use, tableView.separatorStyle = UITableViewCellSeparatorStyle.None;. The consumer side is relatively simple, see example below:

private func stockCell(tableView: UITableView, indexPath:NSIndexPath) -> UITableViewCell {
  var cell : SNStockCell? = tableView.dequeueReusableCellWithIdentifier(stockCellReuseIdentifier) as? SNStockCell
  if (cell == nil) {
    cell = SNStockCell(reuseIdentifier:stockCellReuseIdentifier, primaryTextColor:primaryTextColor, secondaryTextColor:secondaryTextColor)
  }
  cell!.configureWithStock(stockAtIndexPath(indexPath))
  cell!.showsCustomLineSeparator = true
  cell!.customLineSeparatorColor = tintColor
  return cell!
}

In C++11, you can use std::any_of instead.

An example to find if there is any zero in the array:

std::array<int,3> foo = {0,1,-1};
if ( std::any_of(foo.begin(), foo.end(), [](int i){return i==0;}) )
std::cout << "zero found...";

These are the easiest solutions.

1. By Index of

   string title = "STRING";
   
   if (title.IndexOf("string", 0, StringComparison.CurrentCultureIgnoreCase) != -1)
   {
       // contains 
   }
   

2. By Changing case

   string title = "STRING";
   
   bool contains = title.ToLower().Contains("string")
   

3. By Regex

   Regex.IsMatch(title, "string", RegexOptions.IgnoreCase);
   

I have been making use of

<script type="text/javascript" src="{{ URL::asset('js/jquery.js') }}"></script> 
for javascript and 
     <link rel="stylesheet" href="{{ URL::asset('css/main.css') }}">
for css, this points to the public directory, so you need to keep your css and js files there.

Why not try this?

html:

<p>
  a b c
</p>

js:

$("p").text().trim();

After a while trying to build a function to get an integer with the last row in a single column, this worked fine:

    function lastRow() {
    var spreadsheet = SpreadsheetApp.getActiveSheet();
    spreadsheet.getRange('B1').activate();
    var columnB = spreadsheet.getSelection().getNextDataRange(SpreadsheetApp.Direction.DOWN).activate();
    var numRows = columnB.getLastRow();
    var nextRow = numRows + 1; 
    }

man test

if [ -e file ]; then
...  
fi

will work for dir\file.

In Kotlin Android EditText listener is set using,

   val searchTo : EditText = findViewById(R.id.searchTo)
   searchTo.addTextChangedListener(object : TextWatcher {
    override fun afterTextChanged(s: Editable) {

        // you can call or do what you want with your EditText here

        // yourEditText...
    }

    override fun beforeTextChanged(s: CharSequence, start: Int, count: Int, after: Int) {}
    override fun onTextChanged(s: CharSequence, start: Int, before: Int, count: Int) {}
})

In some cases, instead of relying on downward API, programmatically reading the local IP address (from network interfaces) from inside of the container also works.

For example, in golang: https://stackoverflow.com/a/31551220/6247478

Here is the most simple way.

import tkinter as tk

root = tk.Tk()

root.geometry('200x200')
root.resizable(width=0, height=0)

root.mainloop()

I don't think there is anything to specify. It's pretty straight forward.

To add an Activity using Android Studio.

This step is same as adding Fragment, Service, Widget, and etc. Screenshot provided.

[UPDATE] Android Studio 3.5. Note that I have removed the steps for the older version. I assume almost all is using version 3.x.

1. Right click either java package/java folder/module, I recommend to select a java package then right click it so that the destination of the Activity will be saved there
2. Select/Click New
3. Select Activity
4. Choose an Activity that you want to create, probably the basic one.

To add a Service, or a BroadcastReceiver, just do the same step.

Add the function:

function scrollToForm() {
  document.querySelector('#form').scrollIntoView({behavior: 'smooth'});
}

Trigger the function:

<a href="javascript: scrollToForm();">Jump to form</a>

Use DateTime.TryParseExact() if you want to match against a specific date format

 string format = "ddd dd MMM h:mm tt yyyy";
DateTime dateTime;
if (DateTime.TryParseExact(dateString, format, CultureInfo.InvariantCulture,
    DateTimeStyles.None, out dateTime))
{
    Console.WriteLine(dateTime);
}
else
{
    Console.WriteLine("Not a date");
}

Similar to this answer, though I used a temporary table instead:

CREATE TEMPORARY TABLE duplicates (
    SELECT payer_email
    FROM paypal_ipn_orders
    GROUP BY payer_email
    HAVING COUNT(id) > 1
);
SELECT id, payer_email
FROM paypal_ipn_orders AS p
INNER JOIN duplicates AS d ON d.payer_email=p.payer_email;

You can make use of java.net.URL and/or java.net.URLConnection.

URL url = new URL("https://stackoverflow.com");

try (BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"))) {
    for (String line; (line = reader.readLine()) != null;) {
        System.out.println(line);
    }
}

Also see the Oracle's simple tutorial on the subject. It's however a bit verbose. To end up with less verbose code, you may want to consider Apache HttpClient instead.

By the way: if your next question is "How to process HTML result?", then the answer is "Use a HTML parser. No, don't use regex for this.".

convert element's textContent to lowercase with JS..

el.textContent = el.textContent.toLowerCase();

then just use css..

text-transform: capitalize;

Because the accepted answer isn't on the same planet as BS3, I'll share what I'm using to achieve nearly full-width capabilities.

First off, this is cheating. It's not really fluid width - but it appears to be - depending on the size of the screen viewing the site.

The problem with BS3 and fluid width sites is that they have taken this "mobile first" approach, which requires that they define every freaking screen width up to what they consider to be desktop (1200px) I'm working on a laptop with a 1900px wide screen - so I end up with 350px on either side of the content at what BS3 thinks is a desktop sized width.

They have defined 10 screen widths (really only 5, but anyway). I don't really feel comfortable changing those, because they are common widths. So, I chose to define some extra widths for BS to choose from when deciding the width of the container class.

The way I use BS is to take all of the Bootstrap provided LESS files, omit the variables.less file to provide my own, and add one of my own to the end to override the things I want to change. Within my less file, I add the following to achieve 2 common screen width settings:

@media screen and (min-width: 1600px) {
    .container {
        max-width: (1600px - @grid-gutter-width);
    }
}
@media screen and (min-width: 1900px) {
    .container {
        max-width: (1900px - @grid-gutter-width);
    }
}

These two settings set the example for what you need to do to achieve different screen widths. Here, you get full width at 1600px, and 1900px. Any less than 1600 - BS falls back to the 1200px width, then to 768px and so forth - down to phone size.

If you have larger to support, just create more @media screen statements like these. If you're building the CSS instead, you'll want to determine what gutter width was used and subtract it from your target screen width.

Update:

Bootstrap 3.0.1 and up (so far) - it's as easy as setting @container-large-desktop to 100%

ViewParents in general can't remove views, but ViewGroups can. You need to cast your parent to a ViewGroup (if it is a ViewGroup) to accomplish what you want.

For example:

View namebar = View.findViewById(R.id.namebar);
((ViewGroup) namebar.getParent()).removeView(namebar);

Note that all Layouts are ViewGroups.

I would go for the second, the token system.

Did you know about ember-auth or ember-simple-auth? They both use the token based system, like ember-simple-auth states:

A lightweight and unobtrusive library for implementing token based authentication in Ember.js applications. http://ember-simple-auth.simplabs.com

They have session management, and are easy to plug into existing projects too.

There is also an Ember App Kit example version of ember-simple-auth: Working example of ember-app-kit using ember-simple-auth for OAuth2 authentication.

I think what the OP wanted to do was to load a style sheet asynchronously and add it. This works for me in Chrome 22, FF 16 and IE 8 for sets of CSS rules stored as text:

$.ajax({
    url: href,
    dataType: 'text',
    success: function(data) {
        $('<style type="text/css">\n' + data + '</style>').appendTo("head");                    
    }                  
});

In my case, I also sometimes want the loaded CSS to replace CSS that was previously loaded this way. To do that, I put a comment at the beginning, say "/* Flag this ID=102 */", and then I can do this:

// Remove old style
$("head").children().each(function(index, ele) {
    if (ele.innerHTML && ele.innerHTML.substring(0, 30).match(/\/\* Flag this ID=102 \*\//)) {
        $(ele).remove();
        return false;    // Stop iterating since we removed something
    }
});

As others have said, the second approach is usually preferred.

The two code snippets are not exactly equivalent however: the first one actually sets window.opener to the window object itself, whereas the second will leave it as it is, at least under Firefox.

Unlike the other answers that use a formatter, you can also just add an "0" text in front of each number inside of the loop, like this:

for myInt in 1...3 {
    println("0" + "\(myInt)")
}

But formatter is often better when you have to add suppose a designated amount of 0s for each seperate number. If you only need to add one 0, though, then it's really just your pick.

Look closely at the two dashes in

unzipRelease –Src '$ReleaseFile' -Dst '$Destination'

This first one is not a normal dash but an en-dash (– in HTML). Replace that with the dash found before Dst.

I have just experienced this issue in one of my MySQL db's and I looked at the phpMyAdmin answer here. However the best way I fixed it in phpMyAdmin was in the affected table, drop the id column and make a fresh/new id column (adding A-I -autoincrement-). This restored my table id correctly-simples! Hope that helps (no MySQL code needed-I hope to learn to use that but later!) anyone else with this problem.

This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.

In standard SQL one would write:

SELECT t0.foo, t1.bar
  FROM FIRST_TABLE t0
 RIGHT OUTER JOIN SECOND_TABLE t1;

Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :

Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]

Here's a link that offers a few choices. I was searching for a simple spec I could follow rather than having to rely on a partially defined one.

readline is specifically designed to work with terminal (that is process.stdin.isTTY === true). There are a lot of modules which provide split functionality for generic streams, like split. It makes things super-easy:

process.stdin.pipe(require('split')()).on('data', processLine)

function processLine (line) {
  console.log(line + '!')
}

You can try the following:

gitk --all

You can tell gitk what to display using anything that git rev-list understands, so if you just want a few branches, you can do:

gitk master origin/master origin/experiment

... or more exotic things like:

gitk --simplify-by-decoration --all

The solution I use is. Using firefox
1. using web developer --> Web Console
2. open the java-script file in new tab.
3. Refresh the new tab you should see your new code.
4. Refresh the original page
5. You should see your changes.

You can also put the exclamation mark inside the brackets:

if [[ ! $PATH =~ $temp ]]

but you should anchor your pattern to reduce false positives:

temp=/mnt/silo/bin
pattern="(^|:)${temp}(:|$)"
if [[ ! "${PATH}" =~ ${pattern} ]]

which looks for a match at the beginning or end with a colon before or after it (or both). I recommend using lowercase or mixed case variable names as a habit to reduce the chance of name collisions with shell variables.

Live @Sergey's solution but with integer division.

double value = 23.8764367843;
double rounded = (double) Math.round(value * 100) / 100;
System.out.println(value +" rounded is "+ rounded);

prints

23.8764367843 rounded is 23.88

EDIT: As Sergey points out, there should be no difference between multipling double*int and double*double and dividing double/int and double/double. I can't find an example where the result is different. However on x86/x64 and other systems there is a specific machine code instruction for mixed double,int values which I believe the JVM uses.

for (int j = 0; j < 11; j++) {
    long start = System.nanoTime();
    for (double i = 1; i < 1e6; i *= 1.0000001) {
        double rounded = (double) Math.round(i * 100) / 100;
    }
    long time = System.nanoTime() - start;
    System.out.printf("double,int operations %,d%n", time);
}
for (int j = 0; j < 11; j++) {
    long start = System.nanoTime();
    for (double i = 1; i < 1e6; i *= 1.0000001) {
        double rounded = (double) Math.round(i * 100.0) / 100.0;
    }
    long time = System.nanoTime() - start;
    System.out.printf("double,double operations %,d%n", time);
}

Prints

The code I use with jQuery:

$("a.btn_external").click(function() {
    url_to_open = $(this).attr("href");
    window.open(url_to_open, '_blank');
    return false;
});

This is useful to distinguish between the click events of a parent in a child. By using this method, you do not trigger the parent's click event.

—In addition to using "this" for handlebars, and the nested variable within variable block for mustache, you can also use the nested dot in a block for mustache:

    {{#variable}}<span class="text">{{.}}</span>{{/variable}}

~dp0 : d=drive, p=path, %0=full path\name of this batch-file.

cd /d %~dp0 will change the path to the same, where the batch file resides.

See for /? or call / for more details about the %~... modifiers.
See cd /? about the /d switch.

If the migration has been run (read: migrated) then you should roll back your migration to clear the history from your database table. Once you're rolled back you should be able to safely delete your migration file and then proceed with migrating again.

You can use .removeClass and .addClass. More in http://api.jquery.com.

You can use the Conditional Formatting to replace text and NOT effect any formulas. Simply go to the Rule's format where you will see Number, Font, Border and Fill.
Go to the Number tab and select CUSTOM. Then simply type where it says TYPE: what you want to say in QUOTES.

Example.. "OTHER"

you can use this two simple line code :

    display: block;
    margin:auto;

Try to call randomize() before rand() to initialize random generator.

(look at: srand() — why call it only once?)

I had the same problem recently. In my case my windows 7 machine automatically downloaded java and added C:\ProgramData\Oracle\Java\javapath to the beginning of my path environment variable, which messed up my java. Once I got rid of that from the path, it worked.

To trigger the function with click or touch, you could change this:

$(document).click( function () {

To this:

$(document).on('click touchstart', function () {

Or this:

$(document).on('click touch', function () {

The touchstart event fires as soon as an element is touched, the touch event is more like a "tap", i.e. a single contact on the surface. You should really try each of these to see what works best for you. On some devices, touch can be a little harder to trigger (which may be a good or bad thing - it prevents a drag being counted, but an accidental small drag may cause it to not be fired).

You can also add padding for a nice effect.

<img src="image.png" style="padding:1px;border:thin solid black;">

I don't think a message box is the best way to go with this as you would need the VB code running in a loop to check the cell contents, or unless you plan to run the macro manually. In this case I think it would be better to add conditional formatting to the cell to change the background to red (for example) if the value exceeds the upper limit.

$('html,body').animate({ scrollTop: 9999 }, 'slow');

As simple as this , 9999 page height ... big range so it can reach to bottom .

Blanket.js works perfect too.

npm install --save-dev blanket

in front of your test/tests.js

require('blanket')({
    pattern: function (filename) {
        return !/node_modules/.test(filename);
    }
});

run mocha -R html-cov > coverage.html

The innerHTML property is used to get or set the HTML content of an element node.

Example: http://jsfiddle.net/mQMVc/

     // get the element with the "someElement" id, and give it new content
document.getElementById('someElement').innerHTML = "<p>new content</p>";

     // retrieve the content from an element
var content = document.getElementById('someElement').innerHTML;

alert( content );

Is your server single-threaded? If so, what polling / multiplexing function are you using?

Using select() does not work beyond the hard-coded maximum file descriptor limit set at compile-time, which is hopeless (normally 256, or a few more).

poll() is better but you will end up with the scalability problem with a large number of FDs repopulating the set each time around the loop.

epoll() should work well up to some other limit which you hit.

10k connections should be easy enough to achieve. Use a recent(ish) 2.6 kernel.

How many client machines did you use? Are you sure you didn't hit a client-side limit?

If I understand the situation correctly, you are just passing json data through the http body, instead of application/x-www-form-urlencoded data.

You can fetch this data with this snippet:

$request_body = file_get_contents('php://input');

If you are passing json, then you can do:

$data = json_decode($request_body);

$data then contains the json data is php array.

php://input is a so called wrapper.

php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST requests, it is preferable to use php://input instead of $HTTP_RAW_POST_DATA as it does not depend on special php.ini directives. Moreover, for those cases where $HTTP_RAW_POST_DATA is not populated by default, it is a potentially less memory intensive alternative to activating always_populate_raw_post_data. php://input is not available with enctype="multipart/form-data".

If JSON is dynamic as below

{
 "Items": [{
        "Name": "Apple",
        "Price": 12.3
    },
    {
        "Name": "Grape",
        "Price": 3.21
    }
   ],
   "Date": "21/11/2010"
}

Then, Once you install NewtonSoft.Json from NuGet and include it in your project, you can serialize it as

string jsonString = "{\"Items\": [{\"Name\": \"Apple\",\"Price\": 12.3},{\"Name\": \"Grape\",\"Price\": 3.21}],\"Date\": \"21/11/2010\"}";

        dynamic DynamicData = JsonConvert.DeserializeObject(jsonString);

        Console.WriteLine(   DynamicData.Date); // "21/11/2010"
        Console.WriteLine(DynamicData.Items.Count); // 2
        Console.WriteLine(DynamicData.Items[0].Name); // "Apple"

Yes, you can set the line height after defining the border like this:

border-right: 1px solid;
line-height: 10px;

This can done several ways. I usually do it from my class.

From class

.image
{
    width:100%;


}

and for this your html would be:

<img class="image" src="images/image_name">

or if you want to style it using inline styling then you would just have:

<img style="width:100%; height:60px" id="image" src="images/image_name">

I however recommend doing it from your external style-sheet because as your project grows you will realize that the entire thing is easier managed with separate files for your html and your css.

Here is something I wrote for a site I made. It will auto-generate a random flat background-color for any div with the class .flat-color-gen. Jquery is only required for the purposes of adding css to the page; it's not required for the main part of this, which is the generateFlatColorWithOrder() method.

        var blue = 0;
        num = Math.round(num);
        num = num + 1;

The getcode() method (Added in python2.6) returns the HTTP status code that was sent with the response, or None if the URL is no HTTP URL.

>>> a=urllib.urlopen('http://www.google.com/asdfsf')
>>> a.getcode()
404
>>> a=urllib.urlopen('http://www.google.com/')
>>> a.getcode()
200

This is a simple benchmark:

require 'benchmark'

"test123" =~ /1/
=> 4
Benchmark.measure{ 1000000.times { "test123" =~ /1/ } }
=>   0.610000   0.000000   0.610000 (  0.578133)

"test123"[/1/]
=> "1"
Benchmark.measure{ 1000000.times { "test123"[/1/] } }
=>   0.718000   0.000000   0.718000 (  0.750010)

irb(main):019:0> "test123".match(/1/)
=> #<MatchData "1">
Benchmark.measure{ 1000000.times { "test123".match(/1/) } }
=>   1.703000   0.000000   1.703000 (  1.578146)

So =~ is faster but it depends what you want to have as a returned value. If you just want to check if the text contains a regex or not use =~

I don't think there is a way to do that out-of-the-box. A possibly cleaner solution would be:

Stream.of(objects)
    .filter(c -> c instanceof Client)
    .map(c -> (Client) c)
    .map(Client::getID)
    .forEach(System.out::println);

or, as suggested in the comments, you could use the cast method - the former may be easier to read though:

Stream.of(objects)
    .filter(Client.class::isInstance)
    .map(Client.class::cast)
    .map(Client::getID)
    .forEach(System.out::println);

The right solution is to Specialize std::less for your class/Struct.

• Basically maps in cpp are implemented as Binary Search Trees.

1. BSTs compare elements of nodes to determine the organization of the tree.
2. Nodes who's element compares less than that of the parent node are placed on the left of the parent and nodes whose elements compare greater than the parent nodes element are placed on the right. i.e.

For each node, node.left.key < node.key < node.right.key

Every node in the BST contains Elements and in case of maps its KEY and a value, And keys are supposed to be ordered. More About Map implementation : The Map data Type.

In case of cpp maps , keys are the elements of the nodes and values does not take part in the organization of the tree its just a supplementary data .

So It means keys should be compatible with std::less or operator< so that they can be organized. Please check map parameters.

Else if you are using user defined data type as keys then need to give meaning full comparison semantics for that data type.

Solution : Specialize std::less:

The third parameter in map template is optional and it is std::less which will delegate to operator< ,

So create a new std::less for your user defined data type. Now this new std::less will be picked by std::map by default.

namespace std
{
    template<> struct  less<MyClass>
    {
        bool operator() (const MyClass& lhs, const MyClass& rhs) const
        {
            return lhs.anyMemen < rhs.age;
        }
    };

}

Note: You need to create specialized std::less for every user defined data type(if you want to use that data type as key for cpp maps).

Bad Solution: Overloading operator< for your user defined data type. This solution will also work but its very bad as operator < will be overloaded universally for your data type/class. which is undesirable in client scenarios.

There are two ways to approach this problem: numerically and symbolically.

To solve it numerically, you have to first encode it as a "runnable" function - stick a value in, get a value out. For example,

def my_function(x):
    return 2*x + 6

It is quite possible to parse a string to automatically create such a function; say you parse 2x + 6 into a list, [6, 2] (where the list index corresponds to the power of x - so 6*x^0 + 2*x^1). Then:

def makePoly(arr):
    def fn(x):
        return sum(c*x**p for p,c in enumerate(arr))
    return fn

my_func = makePoly([6, 2])
my_func(3)    # returns 12

You then need another function which repeatedly plugs an x-value into your function, looks at the difference between the result and what it wants to find, and tweaks its x-value to (hopefully) minimize the difference.

def dx(fn, x, delta=0.001):
    return (fn(x+delta) - fn(x))/delta

def solve(fn, value, x=0.5, maxtries=1000, maxerr=0.00001):
    for tries in xrange(maxtries):
        err = fn(x) - value
        if abs(err) < maxerr:
            return x
        slope = dx(fn, x)
        x -= err/slope
    raise ValueError('no solution found')

There are lots of potential problems here - finding a good starting x-value, assuming that the function actually has a solution (ie there are no real-valued answers to x^2 + 2 = 0), hitting the limits of computational accuracy, etc. But in this case, the error minimization function is suitable and we get a good result:

solve(my_func, 16)    # returns (x =) 5.000000000000496

Note that this solution is not absolutely, exactly correct. If you need it to be perfect, or if you want to try solving families of equations analytically, you have to turn to a more complicated beast: a symbolic solver.

A symbolic solver, like Mathematica or Maple, is an expert system with a lot of built-in rules ("knowledge") about algebra, calculus, etc; it "knows" that the derivative of sin is cos, that the derivative of kx^p is kpx^(p-1), and so on. When you give it an equation, it tries to find a path, a set of rule-applications, from where it is (the equation) to where you want to be (the simplest possible form of the equation, which is hopefully the solution).

Your example equation is quite simple; a symbolic solution might look like:

=> LHS([6, 2]) RHS([16])

# rule: pull all coefficients into LHS
LHS, RHS = [lh-rh for lh,rh in izip_longest(LHS, RHS, 0)], [0]

=> LHS([-10,2]) RHS([0])

# rule: solve first-degree poly
if RHS==[0] and len(LHS)==2:
    LHS, RHS = [0,1], [-LHS[0]/LHS[1]]

=> LHS([0,1]) RHS([5])

and there is your solution: x = 5.

I hope this gives the flavor of the idea; the details of implementation (finding a good, complete set of rules and deciding when each rule should be applied) can easily consume many man-years of effort.

There is no standard way to do this. You need to use 3rd party tools such as ApexSQL Restore or SQL Virtual Restore. These tools don’t really read the backup file directly. They get SQL Server to “think” of backup files as if these were live databases.

$file = Get-Item -Path "c:/foo/foobar.txt"

I always use the following CSS for a container, to center its content horizontally and vertically.

display: -webkit-box;
display: -moz-box;
display: -ms-flexbox;
display: -webkit-flex;
display: flex;

-webkit-box-align: center;
-moz-box-align: center;
-ms-flex-align: center;
-webkit-align-items: center;
align-items: center;

-webkit-box-pack: center;
-moz-box-pack: center;
-ms-flex-pack: center;
-webkit-justify-content: center;
justify-content: center;

This code will work on all android versions:

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

 //Automatic popping up keyboard on start Activity

     getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

 or

 //avoid automatically appear android keyboard when activity start
     getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
 }

The ObjectDumper class has been known to do that. I've never confirmed, but I've always suspected that the immediate window uses that.

EDIT: I just realized, that the code for ObjectDumper is actually on your machine. Go to:

C:/Program Files/Microsoft Visual Studio 9.0/Samples/1033/CSharpSamples.zip

This will unzip to a folder called LinqSamples. In there, there's a project called ObjectDumper. Use that.

Take a look on life cycle of Activity

Where

***onCreate()***

Called when the activity is first created. This is where you should do all of your normal static set up: create views, bind data to lists, etc. This method also provides you with a Bundle containing the activity's previously frozen state, if there was one. Always followed by onStart().

***onStart()***

Called when the activity is becoming visible to the user. Followed by onResume() if the activity comes to the foreground, or onStop() if it becomes hidden.

And you can write your simple class to take a look when these methods call

public class TestActivity extends Activity {
    /** Called when the activity is first created. */

    private final static String TAG = "TestActivity";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Log.i(TAG, "On Create .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onDestroy()
    */
    @Override
    protected void onDestroy() { 
        super.onDestroy();
        Log.i(TAG, "On Destroy .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onPause()
    */
    @Override
    protected void onPause() { 
        super.onPause();
        Log.i(TAG, "On Pause .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onRestart()
    */
    @Override
    protected void onRestart() {
        super.onRestart();
        Log.i(TAG, "On Restart .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onResume()
    */
    @Override
    protected void onResume() {
        super.onResume();
        Log.i(TAG, "On Resume .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onStart()
    */
    @Override
    protected void onStart() {
        super.onStart();
        Log.i(TAG, "On Start .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onStop()
    */
    @Override
    protected void onStop() {
        super.onStop();
        Log.i(TAG, "On Stop .....");
    }
}

Hope this will clear your confusion.

And take a look here for details.

Lifecycle Methods in Details is a very good example and demo application, which is a very good article to understand the life cycle.

The logic is incorrect. It would always return the result of last element in the array.

remIndex = -1;

for (i = 0; i < remSize.length; i++) {      
    if (remSize[i].size == remData.size) {
        remIndex = i
        break;
    }
}

You can use this :

$this->db->select('*');
$this->db->from('mytable');
$this->db->where(name,'Joe');
$bind = array('boss', 'active');
$this->db->where_in('status', $bind);

To animate your 3D object, use the code:

<script>

$(document).ready(function(){

    var x = 100;
    var y = 0;
setInterval(function(){
    x += 1;
    y += 1;
    var element = document.getElementById('cube');
    element.style.webkitTransform = "translateZ(-100px) rotateY("+x+"deg) rotateX("+y+"deg)"; //for safari and chrome
    element.style.MozTransform = "translateZ(-100px) rotateY("+x+"deg) rotateX("+y+"deg)"; //for firefox
},50);
//for other browsers use:   "msTransform",    "OTransform",    "transform"

});

</script>

You can test if your implementation has it:

#include <math.h>
#ifdef NAN
/* NAN is supported */
#endif
#ifdef INFINITY
/* INFINITY is supported */
#endif

The existence of INFINITY is guaranteed by C99 (or the latest draft at least), and "expands to a constant expression of type float representing positive or unsigned infinity, if available; else to a positive constant of type float that overflows at translation time."

NAN may or may not be defined, and "is defined if and only if the implementation supports quiet NaNs for the float type. It expands to a constant expression of type float representing a quiet NaN."

Note that if you're comparing floating point values, and do:

a = NAN;

even then,

a == NAN;

is false. One way to check for NaN would be:

#include <math.h>
if (isnan(a)) { ... }

You can also do: a != a to test if a is NaN.

There is also isfinite(), isinf(), isnormal(), and signbit() macros in math.h in C99.

C99 also has nan functions:

#include <math.h>
double nan(const char *tagp);
float nanf(const char *tagp);
long double nanl(const char *tagp);

(Reference: n1256).

int opcion = JOptionPane.showConfirmDialog(null, "Realmente deseas salir?", "Aviso", JOptionPane.YES_NO_OPTION);

if (opcion == 0) { //The ISSUE is here
   System.out.print("si");
} else {

}

I'm not sure what the problem is; running the below works as expected:

<div id="thumb0" class="thumbs" onclick="klikaj('rad1')">knock knock</div>
?<div id="rad1" style="visibility: hidden">hello world</div>????????????????????????????????
<script>
function klikaj(i) {
    document.getElementById(i).style.visibility='visible';

If you want to extract just a simple piece of information, you can get that using git show with the --format=<string> option...and ask it not to give you the diff with --no-patch. This means you can get a printf-style output of whatever you want, which might often be a single field.

For instance, to get just the shortened hash (%h) you could say:

$ git show --format="%h" --no-patch
4b703eb

If you're looking to save that into an environment variable in bash (a likely thing for people to want to do) you can use the $() syntax:

$ GIT_COMMIT="$(git show --format="%h" --no-patch)"

$ echo $GIT_COMMIT
4b703eb

The full list of what you can do is in git show --help. But here's an abbreviated list of properties that might be useful:

• %H commit hash
• %h abbreviated commit hash
• %T tree hash
• %t abbreviated tree hash
• %P parent hashes
• %p abbreviated parent hashes
• %an author name
• %ae author email
• %at author date, UNIX timestamp
• %aI author date, strict ISO 8601 format
• %cn committer name
• %ce committer email
• %ct committer date, UNIX timestamp
• %cI committer date, strict ISO 8601 format
• %s subject
• %f sanitized subject line, suitable for a filename
• %gD reflog selector, e.g., refs/stash@{1}
• %gd shortened reflog selector, e.g., stash@{1}

I agree what apnerve says on the distinction. But in case of css it looks odd. As css also gets downloaded to client by browser. It is not like anchor tag which points to any specific resource. So using href there seems odd to me. Even if its not loaded with the page still without that page cannot look complete and so its not just relationship but like resource which in turn refers to many other resource like images.

Add a class as Public and use it very easily like convertToInt32()

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Web;

  /// <summary>
  /// Summary description for Common
  /// </summary>
  public static class Common
  {
     public static double ConvertToDouble(string Value) {
        if (Value == null) {
           return 0;
        }
        else {
           double OutVal;
           double.TryParse(Value, out OutVal);

           if (double.IsNaN(OutVal) || double.IsInfinity(OutVal)) {
              return 0;
           }
           return OutVal;
        }
     }
  }

Then Call The Function

double DirectExpense =  Common.ConvertToDouble(dr["DrAmount"].ToString());

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

For those who use Spring Boot 2.x

There is no need to do any of the above - Java 8 LocalDateTime is serialised/de-serialised out of the box. I had to do all of the above in 1.x, but with Boot 2.x, it works seamlessly.

See this reference too JSON Java 8 LocalDateTime format in Spring Boot

Found the code that I referred to in my comment above. To test it, do this:

1. In Sheet1 change the cell height and width of say A1 as shown in the snapshot below.
2. Format the cell by right clicking on it to show time format
3. Add two buttons (form controls) on the worksheet and name them as shown in the snapshot
4. Paste this code in a module
5. Right click on the Start Timer button on the sheet and click on Assign Macros. Select StartTimer macro.
6. Right click on the End Timer button on the sheet and click on Assign Macros. Select EndTimer macro.

Now click on Start Timer button and you will see the time getting updated in cell A1. To stop time updates, Click on End Timer button.

Code (TRIED AND TESTED)

Public Declare Function SetTimer Lib "user32" ( _
ByVal HWnd As Long, ByVal nIDEvent As Long, _
ByVal uElapse As Long, ByVal lpTimerFunc As Long) As Long

Public Declare Function KillTimer Lib "user32" ( _
ByVal HWnd As Long, ByVal nIDEvent As Long) As Long

Public TimerID As Long, TimerSeconds As Single, tim As Boolean
Dim Counter As Long

'~~> Start Timer
Sub StartTimer()
    '~~ Set the timer for 1 second
    TimerSeconds = 1
    TimerID = SetTimer(0&, 0&, TimerSeconds * 1000&, AddressOf TimerProc)
End Sub

'~~> End Timer
Sub EndTimer()
    On Error Resume Next
    KillTimer 0&, TimerID
End Sub

Sub TimerProc(ByVal HWnd As Long, ByVal uMsg As Long, _
ByVal nIDEvent As Long, ByVal dwTimer As Long)
    '~~> Update value in Sheet 1
    Sheet1.Range("A1").Value = Time
End Sub

SNAPSHOT

A very direct way is to just use read.table on your character vector:

> read.table(text = text, sep = ".", colClasses = "character")
   V1 V2  V3  V4
1   F US CLE V13
2   F US CA6 U13
3   F US CA6 U13
4   F US CA6 U13
5   F US CA6 U13
6   F US CA6 U13
7   F US CA6 U13
8   F US CA6 U13
9   F US  DL U13
10  F US  DL U13
11  F US  DL U13
12  F US  DL Z13
13  F US  DL Z13

colClasses needs to be specified, otherwise F gets converted to FALSE (which is something I need to fix in "splitstackshape", otherwise I would have recommended that :) )

Update (> a year later)...

Alternatively, you can use my cSplit function, like this:

cSplit(as.data.table(text), "text", ".")
#     text_1 text_2 text_3 text_4
#  1:      F     US    CLE    V13
#  2:      F     US    CA6    U13
#  3:      F     US    CA6    U13
#  4:      F     US    CA6    U13
#  5:      F     US    CA6    U13
#  6:      F     US    CA6    U13
#  7:      F     US    CA6    U13
#  8:      F     US    CA6    U13
#  9:      F     US     DL    U13
# 10:      F     US     DL    U13
# 11:      F     US     DL    U13
# 12:      F     US     DL    Z13
# 13:      F     US     DL    Z13

Or, separate from "tidyr", like this:

library(dplyr)
library(tidyr)

as.data.frame(text) %>% separate(text, into = paste("V", 1:4, sep = "_"))
#    V_1 V_2 V_3 V_4
# 1    F  US CLE V13
# 2    F  US CA6 U13
# 3    F  US CA6 U13
# 4    F  US CA6 U13
# 5    F  US CA6 U13
# 6    F  US CA6 U13
# 7    F  US CA6 U13
# 8    F  US CA6 U13
# 9    F  US  DL U13
# 10   F  US  DL U13
# 11   F  US  DL U13
# 12   F  US  DL Z13
# 13   F  US  DL Z13

If you really need to use an array instead of a list, then you can create an array whose size is calculated at run time like so...

e.g i want a two dimensional array of size n by n. n will be gotten at run time from the user

int n = 0;
bool isInteger = int.TryPase(Console.ReadLine(), out n);
var x = new int[n,n];

When passing an array as a parameter, this

void arraytest(int a[])

means exactly the same as

void arraytest(int *a)

so you are modifying the values in main.

For historical reasons, arrays are not first class citizens and cannot be passed by value.

The TimeOfDay property returns a TimeSpan value.

Try the following code:

TimeSpan time = DateTime.Now.TimeOfDay;

if (time > new TimeSpan(11, 59, 00)        //Hours, Minutes, Seconds
 && time < new TimeSpan(13, 01, 00)) {
    //match found
}

Also, new DateTime() is the same as DateTime.MinValue and will always be equal to 1/1/0001 12:00:00 AM. (Value types cannot have non-empty default values) You want to use DateTime.Now.

You can use the fuser command, like:

fuser file_name

You will receive a list of processes using the file.

You can use different flags with it, in order to receive a more detailed output.

You can find more info in the fuser's Wikipedia article, or in the man pages.

In case you're already using the transform property for positioning your element (as I currently am), you can also animate the top margin:

.ball {
  animation: bounce 1s infinite alternate;
  -webkit-animation: bounce 1s infinite alternate;
}

@keyframes bounce {
  from {
    margin-top: 0;
  }
  to {
    margin-top: -15px;
  }
}

In order to use nslookup, host or gethostbyname() then the target's name will need to be registered with DNS or statically defined in the hosts file on the machine running your program. Yes, you could connect to the target with SSH or some other application and query it directly, but for a generic solution you'll need some sort of DNS entry for it.

Static type systems seek to eliminate certain errors statically, inspecting the program without running it and attempting to prove soundness in certain respects. Some type systems are able to catch more errors than others. For example, C# can eliminate null pointer exceptions when used properly, whereas Java has no such power. Twelf has a type system which actually guarantees that proofs will terminate, "solving" the halting problem.

However, no type system is perfect. In order to eliminate a particular class of errors, they must also reject certain perfectly valid programs which violate the rules. This is why Twelf doesn't really solve the halting problem, it just avoids it by throwing out a large number of perfectly valid proofs which happen to terminate in odd ways. Likewise, Java's type system rejects Clojure's PersistentVector implementation due to its use of heterogeneous arrays. It works at runtime, but the type system cannot verify it.

For that reason, most type systems provide "escapes", ways to override the static checker. For most languages, these take the form of casting, though some (like C# and Haskell) have entire modes which are marked as "unsafe".

Subjectively, I like static typing. Implemented properly (hint: not Java), a static type system can be a huge help in weeding out errors before they crash the production system. Dynamically typed languages tend to require more unit testing, which is tedious at the best of times. Also, statically typed languages can have certain features which are either impossible or unsafe in dynamic type systems (implicit conversions spring to mind). It's all a question of requirements and subjective taste. I would no more build the next Eclipse in Ruby than I would attempt to write a backup script in Assembly or patch a kernel using Java.

Oh, and people who say that "x typing is 10 times more productive than y typing" are simply blowing smoke. Dynamic typing may "feel" faster in many cases, but it loses ground once you actually try to make your fancy application run. Likewise, static typing may seem like it's the perfect safety net, but one look at some of the more complicated generic type definitions in Java sends most developers scurrying for eye blinders. Even with type systems and productivity, there is no silver bullet.

Final note: don't worry about performance when comparing static with dynamic typing. Modern JITs like V8 and TraceMonkey are coming dangerously-close to static language performance. Also, the fact that Java actually compiles down to an inherently dynamic intermediate language should be a hint that for most cases, dynamic typing isn't the huge performance-killer that some people make it out to be.

Okay, this is still not the best possible solution, but a nice point to start. I wrote a little Java app that calculates the contrast ratio of two colors and only processes colors with a ratio of 5:1 or better - this ratio and the formula I use has been released by the W3C and will probably replace the current recommendation (which I consider very limited). It creates a file in the current working dir named "chosen-font-colors.html", with the background color of your choice and a line of text in every color that passed this W3C test. It expects a single argument, being the background color.

E.g. you can call it like this

java FontColorChooser 33FFB4

then just open the generated HTML file in a browser of your choice and choose a color from the list. All colors given passed the W3C test for this background color. You can change the cut off by replacing 5 with a number of your choice (lower numbers allow weaker contrasts, e.g. 3 will only make sure contrast is 3:1, 10 will make sure it is at least 10:1) and you can also cut off to avoid too high contrasts (by making sure it is smaller than a certain number), e.g. adding

|| cDiff > 18.0

to the if clause will make sure contrast won't be too extreme, as too extreme contrasts can stress your eyes. Here's the code and have fun playing around with it a bit :-)

import java.io.*;

/* For text being readable, it must have a good contrast difference. Why?
 * Your eye has receptors for brightness and receptors for each of the colors
 * red, green and blue. However, it has much more receptors for brightness
 * than for color. If you only change the color, but both colors have the
 * same contrast, your eye must distinguish fore- and background by the
 * color only and this stresses the brain a lot over the time, because it
 * can only use the very small amount of signals it gets from the color
 * receptors, since the breightness receptors won't note a difference.
 * Actually contrast is so much more important than color that you don't
 * have to change the color at all. E.g. light red on dark red reads nicely
 * even though both are the same color, red.
 */

Using wget, which is usually part of default system installation:

bash <(wget -qO- http://mywebsite.com/myscript.txt)

A few years late but this might help someone if you are using eval or backtick substitution:

postDataJson="{\"guid\":\"$guid\",\"auth_token\":\"$token\"}"

Using sed to strip quotes from beginning and end of response

$(curl --silent -H "Content-Type: application/json" https://${target_host}/runs/get-work -d ${postDataJson} | sed -e 's/^"//' -e 's/"$//')

Think of it as the natural orthogonal operation to split.

I understand why it is applicable to anything iterable and so can't easily be implemented just on list.

For readability, I'd like to see it in the language but I don't think that is actually feasible - if iterability were an interface then it could be added to the interface but it is just a convention and so there's no central way to add it to the set of things which are iterable.

The above answers will position the inner element at the top of the overflow element even if it's in view inside the overflow element. I didn't want that so I modified it to not change the scroll position if the element is in view.

jQuery.fn.scrollTo = function(elem, speed) {
    var $this = jQuery(this);
    var $this_top = $this.offset().top;
    var $this_bottom = $this_top + $this.height();
    var $elem = jQuery(elem);
    var $elem_top = $elem.offset().top;
    var $elem_bottom = $elem_top + $elem.height();

    if ($elem_top > $this_top && $elem_bottom < $this_bottom) {
        // in view so don't do anything
        return;
    }
    var new_scroll_top;
    if ($elem_top < $this_top) {
        new_scroll_top = {scrollTop: $this.scrollTop() - $this_top + $elem_top};
    } else {
        new_scroll_top = {scrollTop: $elem_bottom - $this_bottom + $this.scrollTop()};
    }
    $this.animate(new_scroll_top, speed === undefined ? 100 : speed);
    return this;
};

It turns out that you can set window.undefined to whatever you want, and so get object.x !== undefined when object.x is the real undefined. In my case I inadvertently set undefined to null.

The easiest way to see this happen is:

window.undefined = null;
alert(window.xyzw === undefined); // shows false

Of course, this is not likely to happen. In my case the bug was a little more subtle, and was equivalent to the following scenario.

var n = window.someName; // someName expected to be set but is actually undefined
window[n]=null; // I thought I was clearing the old value but was actually changing window.undefined to null
alert(window.xyzw === undefined); // shows false

A very simple way of doing this is to use reset_index() method.For a data frame df use the code below:

df.reset_index(inplace=True)

This way, the index will become a column, and by using inplace as True,this become permanent change.

The value of hjust and vjust are only defined between 0 and 1:

• 0 means left-justified
• 1 means right-justified

Source: ggplot2, Hadley Wickham, page 196

(Yes, I know that in most cases you can use it beyond this range, but don't expect it to behave in any specific way. This is outside spec.)

hjust controls horizontal justification and vjust controls vertical justification.

An example should make this clear:

td <- expand.grid(
    hjust=c(0, 0.5, 1),
    vjust=c(0, 0.5, 1),
    angle=c(0, 45, 90),
    text="text"
)

ggplot(td, aes(x=hjust, y=vjust)) + 
    geom_point() +
    geom_text(aes(label=text, angle=angle, hjust=hjust, vjust=vjust)) + 
    facet_grid(~angle) +
    scale_x_continuous(breaks=c(0, 0.5, 1), expand=c(0, 0.2)) +
    scale_y_continuous(breaks=c(0, 0.5, 1), expand=c(0, 0.2))

To understand what happens when you change the hjust in axis text, you need to understand that the horizontal alignment for axis text is defined in relation not to the x-axis, but to the entire plot (where this includes the y-axis text). (This is, in my view, unfortunate. It would be much more useful to have the alignment relative to the axis.)

DF <- data.frame(x=LETTERS[1:3],y=1:3)
p <- ggplot(DF, aes(x,y)) + geom_point() + 
    ylab("Very long label for y") +
    theme(axis.title.y=element_text(angle=0))


p1 <- p + theme(axis.title.x=element_text(hjust=0)) + xlab("X-axis at hjust=0")
p2 <- p + theme(axis.title.x=element_text(hjust=0.5)) + xlab("X-axis at hjust=0.5")
p3 <- p + theme(axis.title.x=element_text(hjust=1)) + xlab("X-axis at hjust=1")

library(ggExtra)
align.plots(p1, p2, p3)

To explore what happens with vjust aligment of axis labels:

DF <- data.frame(x=c("a\na","b","cdefghijk","l"),y=1:4)
p <- ggplot(DF, aes(x,y)) + geom_point()

p1 <- p + theme(axis.text.x=element_text(vjust=0, colour="red")) + 
        xlab("X-axis labels aligned with vjust=0")
p2 <- p + theme(axis.text.x=element_text(vjust=0.5, colour="red")) + 
        xlab("X-axis labels aligned with vjust=0.5")
p3 <- p + theme(axis.text.x=element_text(vjust=1, colour="red")) + 
        xlab("X-axis labels aligned with vjust=1")


library(ggExtra)
align.plots(p1, p2, p3)

I got a version based on what I saw previously. It helped me a lot to create export files as CSV or TXT. I'm storing a table into a ## Temp Table:

    IF OBJECT_ID('tempdb..##TmpExportFile') IS NOT NULL
DROP TABLE ##TmpExportFile;


DECLARE @columnHeader VARCHAR(8000)
DECLARE @raw_sql nvarchar(3000)

SELECT
              * INTO ##TmpExportFile
              ------ FROM THE TABLE RESULTS YOU WANT TO GET
              ------ COULD BE A TABLE OR A TEMP TABLE BASED ON INNER JOINS
              ------ ,ETC.

FROM TableName -- optional WHERE ....


DECLARE @table_name  VARCHAR(50) = '##TmpExportFile'
SELECT
              @columnHeader = COALESCE(@columnHeader + ',', '') + '''[' + c.name + ']''' + ' as ' + '' + c.name + ''
FROM tempdb.sys.columns c
INNER JOIN tempdb.sys.tables t
              ON c.object_id = t.object_id
WHERE t.NAME = @table_name

print @columnheader

                DECLARE @ColumnList VARCHAR(max)
SELECT
              @ColumnList = COALESCE(@ColumnList + ',', '') + 'CAST([' + c.name + '] AS CHAR(' + LTRIM(STR(max_length)) + '))'
FROM tempdb.sys.columns c
INNER JOIN tempdb.sys.tables t
              ON c.object_id = t.object_id
WHERE t.name = @table_name
print @ColumnList

I found a way to style all previous siblings (opposite of ~) that may work depending on what you need.

Let's say you have a list of links and when hovering on one, all the previous ones should turn red. You can do it like this:

/* default link color is blue */_x000D_
.parent a {_x000D_
  color: blue;_x000D_
}_x000D_
_x000D_
/* prev siblings should be red */_x000D_
.parent:hover a {_x000D_
  color: red;_x000D_
}_x000D_
.parent a:hover,_x000D_
.parent a:hover ~ a {_x000D_
  color: blue;_x000D_
}

<div class="parent">_x000D_
  <a href="#">link</a>_x000D_
  <a href="#">link</a>_x000D_
  <a href="#">link</a>_x000D_
  <a href="#">link</a>_x000D_
  <a href="#">link</a>_x000D_
</div>

I got the same problem until i read that the real problem is about FOCUS the your JFrame has already added Listeners but tour frame is never on Focus because you got a lot of components inside your JFrame that also are focusable so try:

JFrame.setFocusable(true);

Good Luck
