Programs & Examples On #Resource leak

I am assuming you are using java 7, thus you get a compiler warning, when you don't close the resource you should close your scanner usually in a finally block.

Scanner scanner = null;
try {
    scanner = new Scanner(System.in);
    //rest of the code
}
finally {
    if(scanner!=null)
        scanner.close();
}

Or even better: use the new Try with resource statement:

try(Scanner scanner = new Scanner(System.in)){
    //rest of your code
}

Just / refers to the root of your website from the public html folder. DOCUMENT_ROOT refers to the local path to the folder on the server that contains your website.

For example, I have EasyPHP setup on a machine...

$_SERVER["DOCUMENT_ROOT"] gives me file:///C:/Program%20Files%20(x86)/EasyPHP-5.3.9/www but any file I link to with just / will be relative to my www folder.

If you want to give the absolute path to a file on your server (from the server's root) you can use DOCUMENT_ROOT. if you want to give the absolute path to a file from your website's root, use just /.

I can't see why you would care. Other than the "don't use ports below 1024" privilege rule, you should be able to use any port because your clients should be configurable to talk to any IP address and port!

If they're not, then they haven't been done very well. Go back and do them properly :-)

In other words, run the server at IP address X and port Y then configure clients with that information. Then, if you find you must run a different server on X that conflicts with your Y, just re-configure your server and clients to use a new port. This is true whether your clients are code, or people typing URLs into a browser.

I, like you, wouldn't try to get numbers assigned by IANA since that's supposed to be for services so common that many, many environments will use them (think SSH or FTP or TELNET).

Your network is your network and, if you want your servers on port 1234 (or even the TELNET or FTP ports for that matter), that's your business. Case in point, in our mainframe development area, port 23 is used for the 3270 terminal server which is a vastly different beast to telnet. If you want to telnet to the UNIX side of the mainframe, you use port 1023. That's sometimes annoying if you use telnet clients without specifying port 1023 since it hooks you up to a server that knows nothing of the telnet protocol - we have to break out of the telnet client and do it properly:

telnet big_honking_mainframe_box.com 1023

If you really can't make the client side configurable, pick one in the second range, like 48042, and just use it, declaring that any other software on those boxes (including any added in the future) has to keep out of your way.

There are already so many good answers on this thread! I am going to post this to help anybody trying to do this automatically! To automatically remove unused imports for the whole project this article was really helpful to me.

In the article the author explains it like this:

Make a stand alone tslint file that has the following in it:

{
  "extends": ["tslint-etc"],
  "rules": {
    "no-unused-declaration": true
  }
}

Then run the following command to fix the imports:

 tslint --config tslint-imports.json --fix --project .

Consider fixing any other errors it throws. (I did)

Then check the project works by building it:

ng build

or

ng build name_of_project --configuration=production 

End: If it builds correctly, you have successfully removed imports automatically!

NOTE: This only removes unnecessary imports. It does not provide the other features that VS Code does when using one of the commands previously mentioned.

You are setting the extra with an array. You are then trying to get a single int.

Your code should be:

int[] arrayB = extras.getIntArray("numbers");

I wrote shell script below (named start.sh). Because my package.json has prestart option. So I want to run npm start.

#!/bin/bash
cd /path/to/project
npm start

Then, start start.sh by pm2.

pm2 start start.sh --name appNameYouLike

$str = trim(preg_replace('/\s+/',' ', $str));

The above line of code will remove extra spaces, as well as leading and trailing spaces.

Firstly, it's necessary to know what is a jar file.

From Oracle,

JAR (Java Archive) is a platform-independent file format that aggregates many files into one. Multiple Java applets and their requisite components (.class files, images and sounds) can be bundled in a JAR file and subsequently downloaded to a browser in a single HTTP transaction, greatly improving the download speed. The JAR format also supports compression, which reduces the file size, further improving the download time.

As you can see,

1. It has nothing to do with a Eclipse project. An Eclipse project can be a Java project, C++ project and so on. It's just a self contain project that can be recognized and operated as an unit by Eclipse.
2. The .class files are generally the main part of a jar file. It's impossible to view the source code(.java file) unless you decompile the executable file(.class file) by some tools. Take Eclipse for example, you can choose the plugin Eclipse Class Decompiler as the tool.

Although micahtan's answer is good, it won't work in a static method. If you want to retrieve the name of the current type, this one should work everywhere:

string className = MethodBase.GetCurrentMethod().DeclaringType.Name;

This should make your TextView bold, underlined and italic at the same time.

strings.xml

<resources>
    <string name="register"><u><b><i>Copyright</i></b></u></string>
</resources>

To set this String to your TextView, do this in your main.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/textview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:text="@string/register" />

or In JAVA,

TextView textView = new TextView(this);
textView.setText(R.string.register);

Sometimes the above approach will not be helpful when you might have to use Dynamic Text. So in that case SpannableString comes into action.

String tempString="Copyright";
TextView text=(TextView)findViewById(R.id.text);
SpannableString spanString = new SpannableString(tempString);
spanString.setSpan(new UnderlineSpan(), 0, spanString.length(), 0);
spanString.setSpan(new StyleSpan(Typeface.BOLD), 0, spanString.length(), 0);
spanString.setSpan(new StyleSpan(Typeface.ITALIC), 0, spanString.length(), 0);
text.setText(spanString);

OUTPUT

Like @Maximiliangerhardt said, MiniJson do not have the capability to deserialize properly. I used JsonFx and works like a charm. Works with the []

player[] p = JsonReader.Deserialize<player[]>(serviceData);
Debug.Log(p[0].playerId +" "+ p[0].playerLoc+"--"+ p[1].playerId + " " + p[1].playerLoc+"--"+ p[2].playerId + " " + p[2].playerLoc);

Utilities.sleep(milliseconds) creates a 'pause' in program execution, meaning it does nothing during the number of milliseconds you ask. It surely slows down your whole process and you shouldn't use it between function calls. There are a few exceptions though, at least that one that I know : in SpreadsheetApp when you want to remove a number of sheets you can add a few hundreds of millisecs between each deletion to allow for normal script execution (but this is a workaround for a known issue with this specific method). I did have to use it also when creating many sheets in a spreadsheet to avoid the Browser needing to be 'refreshed' after execution.

Here is an example :

function delsheets(){
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var numbofsheet=ss.getNumSheets();// check how many sheets in the spreadsheet
  for (pa=numbofsheet-1;pa>0;--pa){ 
    ss.setActiveSheet(ss.getSheets()[pa]);
    var newSheet = ss.deleteActiveSheet(); // delete sheets begining with the last one
    Utilities.sleep(200);// pause in the loop for 200 milliseconds
  }
  ss.setActiveSheet(ss.getSheets()[0]);// return to first sheet as active sheet (useful in 'list' function)
}

You can use CURL for this purpose see the example code:

$url = "your url";    
$content = json_encode("your data to be sent");

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER,
        array("Content-type: application/json"));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $content);

$json_response = curl_exec($curl);

$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

if ( $status != 201 ) {
    die("Error: call to URL $url failed with status $status, response $json_response, curl_error " . curl_error($curl) . ", curl_errno " . curl_errno($curl));
}


curl_close($curl);

$response = json_decode($json_response, true);

Take a look at boost::assign.

If you are using NodeJS, you can use the build-in util function:

import * as util from "util";
util.format('My string: %s', 'foo');

Document can be found here: https://nodejs.org/api/util.html#util_util_format_format_args

I'm also a newbie to CUDA/Visual studio and encountered the same problem with a couple of the samples. If you run DEBUG-> Start Debugging, then repeatedly step over (F10) you'll see the output window appear and get populated. Normal execution returns nomal completion status 0x0 (as you observed) and the output window is closed.

The point of an interface is to specify the public API. An interface has no state. Any variables that you create are really constants (so be careful about making mutable objects in interfaces).

Basically an interface says here are all of the methods that a class that implements it must support. It probably would have been better if the creators of Java had not allowed constants in interfaces, but too late to get rid of that now (and there are some cases where constants are sensible in interfaces).

Because you are just specifying what methods have to be implemented there is no idea of state (no instance variables). If you want to require that every class has a certain variable you need to use an abstract class.

Finally, you should, generally speaking, not use public variables, so the idea of putting variables into an interface is a bad idea to begin with.

Short answer - you can't do what you want because it is "wrong" in Java.

Edit:

class Tile 
    implements Rectangle 
{
    private int height;
    private int width;

     @Override
    public int getHeight() {
        return height;
    }

    @Override
    public int getWidth() {
        return width;
    }

    @Override
    public void setHeight(int h) {
        height = h;
    }

    @Override
    public void setWidth(int w) { 
        width = w;  
    }
}

an alternative version would be:

abstract class AbstractRectangle 
    implements Rectangle 
{
    private int height;
    private int width;

     @Override
    public int getHeight() {
        return height;
    }

    @Override
    public int getWidth() {
        return width;
    }

    @Override
    public void setHeight(int h) {
        height = h;
    }

    @Override
    public void setWidth(int w) { 
        width = w;  
    }
}

class Tile 
    extends AbstractRectangle 
{
}

This is my solution for this:

https://gist.github.com/BryanMoslo/808f7acb1dafcd049a1aebbeef8c2755

The element recibes a "tooltip-title" attribute with the tooltip text and it is displayed with CSS on hover, I prefer this solution because I don't have to include the tooltip text as a HTML element!

#HTML
<button class="tooltip" tooltip-title="Save">Hover over me</button>

#CSS

body{
    padding: 50px;
}
.tooltip {
    position: relative;
}

.tooltip:before {
    content: attr(tooltip-title);
    min-width: 54px;
    background-color: #999999;
    color: #fff;
    font-size: 12px;
    border-radius: 4px;
    padding: 9px 0;
    position: absolute;
    top: -42px;
    left: 50%;
    margin-left: -27px;
    visibility: hidden;
    opacity: 0;
    transition: opacity 0.3s;
}

.tooltip:after {
    content: "";
    position: absolute;
    top: -9px;
    left: 50%;
    margin-left: -5px;
    border-width: 5px;
    border-style: solid;
    border-color: #999999 transparent transparent;
    visibility: hidden;
    opacity: 0;
    transition: opacity 0.3s;
}

.tooltip:hover:before,
.tooltip:hover:after{
    visibility: visible;
    opacity: 1;
}

You are probably manually calling setVisible(true) on the menu. That can cause some nasty buggy behavior in the menu.

The show(Component, int x, int x) method handles all of the things you need to happen, (Highlighting things on mouseover and closing the popup when necessary) where using setVisible(true) just shows the menu without adding any additional behavior.

To make a right click popup menu simply create a JPopupMenu.

class PopUpDemo extends JPopupMenu {
    JMenuItem anItem;
    public PopUpDemo() {
        anItem = new JMenuItem("Click Me!");
        add(anItem);
    }
}

Then, all you need to do is add a custom MouseListener to the components you would like the menu to popup for.

class PopClickListener extends MouseAdapter {
    public void mousePressed(MouseEvent e) {
        if (e.isPopupTrigger())
            doPop(e);
    }

    public void mouseReleased(MouseEvent e) {
        if (e.isPopupTrigger())
            doPop(e);
    }

    private void doPop(MouseEvent e) {
        PopUpDemo menu = new PopUpDemo();
        menu.show(e.getComponent(), e.getX(), e.getY());
    }
}

// Then on your component(s)
component.addMouseListener(new PopClickListener());

Of course, the tutorials have a slightly more in-depth explanation.

Note: If you notice that the popup menu is appearing way off from where the user clicked, try using the e.getXOnScreen() and e.getYOnScreen() methods for the x and y coordinates.

If you have a background-image, you can do this : Set a rgba() gradient on the background-image.

.img_container {_x000D_
  float: left;_x000D_
  width: 300px;_x000D_
  height: 300px;_x000D_
  display: flex;_x000D_
  justify-content: center;_x000D_
  align-items: center;_x000D_
  border : 1px solid #fff;_x000D_
}_x000D_
_x000D_
.image_original {_x000D_
  background: url(https://i.ibb.co/GkDXWYW/demo-img.jpg);_x000D_
}_x000D_
_x000D_
.image_brighness {_x000D_
  background: linear-gradient(0deg, rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), /* the gradient on top, adjust color and opacity to your taste */_x000D_
  url(https://i.ibb.co/GkDXWYW/demo-img.jpg);_x000D_
}_x000D_
_x000D_
.img_container p {_x000D_
  color: #fff;_x000D_
  font-size: 28px;_x000D_
}

<div class="img_container image_original">_x000D_
  <p>normal</p>_x000D_
</div>_x000D_
<div class="img_container image_brighness ">_x000D_
  <p>less brightness</p>_x000D_
</div>

To know what to clear for sure - add the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Fusion\EnableLog (DWord set to 1).

Then you will see output like below. This tells you where asp.net is attempting to load your DLLs. Clear this directory.

LOG: This bind starts in default load context.
LOG: Using application configuration file: c:\app\AtlasAdvisor\web\web.config
LOG: Using host configuration file: C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet.config

You need URL Rewrite module, preferably v2 (I have no v1 installed, so cannot guarantee that it will work there, but it should).

Here is an example of such web.config -- it will force HTTPS for ALL resources (using 301 Permanent Redirect):

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <clear />
                <rule name="Redirect to https" stopProcessing="true">
                    <match url=".*" />
                    <conditions>
                        <add input="{HTTPS}" pattern="off" ignoreCase="true" />
                    </conditions>
                    <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" redirectType="Permanent" appendQueryString="false" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

P.S. This particular solution has nothing to do with ASP.NET/PHP or any other technology as it's done using URL rewriting module only -- it is processed at one of the initial/lower levels -- before request gets to the point where your code gets executed.

its very easy. Use the bellow code, Its works for me. Here I have used fontawesome icon but you can use anything as image or any other Icon's code.

    $(document).ready(function(){
        $('.slider').slick({
            autoplay:true,
            arrows: true,
            prevArrow:"<button type='button' class='slick-prev pull-left'><i class='fa fa-angle-left' aria-hidden='true'></i></button>",
            nextArrow:"<button type='button' class='slick-next pull-right'><i class='fa fa-angle-right' aria-hidden='true'></i></button>"
        });
    });

My solution in Python with sqlite3:

import sqlite3
import re

def match(expr, item):
    return re.match(expr, item) is not None

conn = sqlite3.connect(':memory:')
conn.create_function("MATCHES", 2, match)
cursor = conn.cursor()
cursor.execute("SELECT MATCHES('^b', 'busy');")
print cursor.fetchone()[0]

cursor.close()
conn.close()

If regex matches, the output would be 1, otherwise 0.

To turn off foreign key constraint globally, do the following:

SET GLOBAL FOREIGN_KEY_CHECKS=0;

and remember to set it back when you are done

SET GLOBAL FOREIGN_KEY_CHECKS=1;

WARNING: You should only do this when you are doing single user mode maintenance. As it might resulted in data inconsistency. For example, it will be very helpful when you are uploading large amount of data using a mysqldump output.

You should adhere your application to the XDG Base Directory Specification. Most answers here are either obsolete or wrong.

Your application should store and load data and configuration files to/from the directories pointed by the following environment variables:

• $XDG_DATA_HOME (default: "$HOME/.local/share"): user-specific data files.
• $XDG_CONFIG_HOME (default: "$HOME/.config"): user-specific configuration files.
• $XDG_DATA_DIRS (default: "/usr/local/share/:/usr/share/"): precedence-ordered set of system data directories.
• $XDG_CONFIG_DIRS (default: "/etc/xdg"): precedence-ordered set of system configuration directories.
• $XDG_CACHE_HOME (default: "$HOME/.cache"): user-specific non-essential data files.

You should first determine if the file in question is:

1. A configuration file ($XDG_CONFIG_HOME:$XDG_CONFIG_DIRS);
2. A data file ($XDG_DATA_HOME:$XDG_DATA_DIRS); or
3. A non-essential (cache) file ($XDG_CACHE_HOME).

It is recommended that your application put its files in a subdirectory of the above directories. Usually, something like $XDG_DATA_DIRS/<application>/filename or $XDG_DATA_DIRS/<vendor>/<application>/filename.

When loading, you first try to load the file from the user-specific directories ($XDG_*_HOME) and, if failed, from system directories ($XDG_*_DIRS). When saving, save to user-specific directories only (since the user probably won't have write access to system directories).

For other, more user-oriented directories, refer to the XDG User Directories Specification. It defines directories for the Desktop, downloads, documents, videos, etc.

Tried other variants, this can be proper

    Logger logger = Logger.getLogger(MyClass.class.getName());        
    Level level = Level.ALL;
    for(Handler h : java.util.logging.Logger.getLogger("").getHandlers())    
        h.setLevel(level);
    logger.setLevel(level);
// this must be shown
    logger.fine("fine");
    logger.info("info");

You can do that: Postman -> Import -> Link -> {root_url}/v2/api-docs

I was getting a very similar situation where the HttpWebRequest wasn't picking up the correct proxy details by default and setting the UseDefaultCredentials didn't work either. Forcing the settings in code however worked a treat:

IWebProxy proxy = myWebRequest.Proxy;
if (proxy != null) {
    string proxyuri = proxy.GetProxy(myWebRequest.RequestUri).ToString();
    myWebRequest.UseDefaultCredentials = true;
    myWebRequest.Proxy = new WebProxy(proxyuri, false);
    myWebRequest.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
}

and because this uses the default credentials it should not ask the user for their details.

The --cached didn't work for me, ... where, inspired by git log

git diff origin/<branch>..<branch> did.

if you want to check the text of selected option regardless if its the 1st child.

var a = $("#select_id option:selected").text();
alert(a); //check if the value is correct.
if(a == "value") {-- execute code --}

basicly

package main

import (
    "fmt"
    "os"
)

func fileExists(path string) bool {
    _, err := os.Stat(path)
    return !os.IsNotExist(err)
}

func main() {

    var file string = "foo.txt"
    exist := fileExists(file)
    
    if exist {
        fmt.Println("file exist")
    } else {

        fmt.Println("file not exists")
    }

}

run example

other way

with os.Open

package main

import (
    "fmt"
    "os"
)

func fileExists(path string) bool {
    _, err := os.Open(path) // For read access.
    return err == nil

}

func main() {

    fmt.Println(fileExists("d4d.txt"))

}

run it

For renaming recursively I use the following commands:

find -iname \*.* | rename -v "s/ /-/g"

It works!!! Use the following code:

<style>
div.select-container{
   border: 1px black;width:200px;
}
</style>


<div id="status" class="select-container">
    <select name="status">
        <option value="" >Please Select...</option>
        <option value="option1">Option 1</option>
        <option value="option2">Option 2</option>
    </select>
</div>

You could use

kubectl describe pod `hostname` | grep IP | sed -E 's/IP:[[:space:]]+//'

which is based on what @mibbit suggested.

This takes the following facts into account:

• hostname is set to POD's name but this might change in the future
• kubectl was manually placed in the container (possibly when the image was built)
• Kubernetes provides a service account credential to the container implicitly as described in Accessing the Cluster / Accessing the API from a Pod, i.e. /var/run/secrets/kubernetes.io/serviceaccount in the container

I think the answer in the link below is better

How to change the track color of a SwitchCompat

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
   ...
   <!-- Active thumb color & Active track color(30% transparency) -->
   <item name="colorControlActivated">@color/theme</item>
   <!-- Inactive thumb color -->
   <item name="colorSwitchThumbNormal">@color/grey300</item>
   <!-- Inactive track color(30% transparency) -->
   <item name="android:colorForeground">@color/grey600</item>
   ...
</style>

If anyone was wondering , how you could do this for your entire application without having to make all your activities extend a common base class in Kotlin , see the example below :

class InteractiveStoryApplication: Application() {
override fun onCreate() {
    super.onCreate()
    registerActivityLifecycleCallbacks(object: ActivityLifecycleCallbacks {
        override fun onActivityCreated(activity: Activity?, savedInstanceState: Bundle?) {
            activity?.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
        }

        override fun onActivityPaused(activity: Activity?) {
        }

        override fun onActivityResumed(activity: Activity?) {
        }

        override fun onActivityDestroyed(activity: Activity?) {
        }

        override fun onActivitySaveInstanceState(activity: Activity?, outState: Bundle?) {
        }

        override fun onActivityStarted(activity: Activity?) {
        }

        override fun onActivityStopped(activity: Activity?) {
        }
    })
}
}

and then you have to add your common base class in AndroidManifest like so:

<application android:allowBackup="true"
android:name=".InteractiveStoryApplication"

To convert a string having the form a="[[1, 3], [2, -6]]" I wrote yet not optimized code:

matrixAr = []
mystring = "[[1, 3], [2, -4], [19, -15]]"
b=mystring.replace("[[","").replace("]]","") # to remove head [[ and tail ]]
for line in b.split('], ['):
    row =list(map(int,line.split(','))) #map = to convert the number from string (some has also space ) to integer
    matrixAr.append(row)
print matrixAr

TOP and square brackets are specific to Transact-SQL. In ANSI SQL one uses LIMIT and backticks (`).

select * from `Table_Name` LIMIT 5;

You can use name property to get the function name, unless you're using an anonymous function

For example:

var Person = function Person () {
  this.someMethod = function () {};
};

Person.prototype.getSomeMethodName = function () {
  return this.someMethod.name;
};

var p = new Person();
// will return "", because someMethod is assigned with anonymous function
console.log(p.getSomeMethodName());

now let's try with named function

var Person = function Person () {
  this.someMethod = function someMethod() {};
};

now you can use

// will return "someMethod"
p.getSomeMethodName()

I would one-up'd mightymada's answer if I had the reputation - I just implemented an asp.net HTML to PDF solution using Pechkin. results are wonderful.

There is a nuget package for Pechkin, but as the above poster mentions in his blog (http://codeutil.wordpress.com/2013/09/16/convert-html-to-pdf/ - I hope she doesn't mind me reposting it), there's a memory leak that's been fixed in this branch:

https://github.com/tuespetre/Pechkin

The above blog has specific instructions for how to include this package (it's a 32 bit dll and requires .net4). here is my code. The incoming HTML is actually assembled via HTML Agility pack (I'm automating invoice generations):

public static byte[] PechkinPdf(string html)
{
  //Transform the HTML into PDF
  var pechkin = Factory.Create(new GlobalConfig());
  var pdf = pechkin.Convert(new ObjectConfig()
                          .SetLoadImages(true).SetZoomFactor(1.5)
                          .SetPrintBackground(true)
                          .SetScreenMediaType(true)
                          .SetCreateExternalLinks(true), html);

  //Return the PDF file
  return pdf;
}

again, thank you mightymada - your answer is fantastic.

Aggregate means collection of something.
root is like top node of tree, from where we can access everything like <html> node in web page document.
Blog Analogy, A user can have many posts and each post can have many comments. so if we fetch any user then it can act as root to access all the related posts and further comments of those posts. These are all together said to be collection or Aggregated

Updated Answer

^{* Updated answer which support the v2.1.1** bootstrap version stylesheet.}

^{**But be careful because this solution has been removed from v3}

Just wanted to point out that this solution is not needed anymore as the latest bootstrap now supports multi-level dropdowns by default. You can still use it if you're on older versions but for those who updated to the latest (v2.1.1 at the time of writing) it is not needed anymore. Here is a fiddle with the updated default multi-level dropdown straight from the documentation:

http://jsfiddle.net/2Smgv/2858/

Original Answer

There have been some issues raised on submenu support over at github and they are usually closed by the bootstrap developers, such as this one, so i think it is left to the developers using the bootstrap to work something out. Here is a demo i put together showing you how you can hack together a working sub-menu.

Relevant code

CSS

.dropdown-menu .sub-menu {
    left: 100%;
    position: absolute;
    top: 0;
    visibility: hidden;
    margin-top: -1px;
}

.dropdown-menu li:hover .sub-menu {
    visibility: visible;
    display: block;
}

.navbar .sub-menu:before {
    border-bottom: 7px solid transparent;
    border-left: none;
    border-right: 7px solid rgba(0, 0, 0, 0.2);
    border-top: 7px solid transparent;
    left: -7px;
    top: 10px;
}
.navbar .sub-menu:after {
    border-top: 6px solid transparent;
    border-left: none;
    border-right: 6px solid #fff;
    border-bottom: 6px solid transparent;
    left: 10px;
    top: 11px;
    left: -6px;
}

Created my own .sub-menu class to apply to the 2-level drop down menus, this way we can position them next to our menu items. Also modified the arrow to display it on the left of the submenu group.

Demo

That's the way I'd prefer to see if I was maintaining your code. If you manage to find a faster solution, it's going to be very esoteric, and you should really bury it inside of a method that describes what it does.

(does it still work without the ToArray)?

You can try this code into your activity

    private void startWebView(WebView webView,String url) {
 webView.setWebViewClient(new WebViewClient() {
            ProgressDialog progressDialog;

            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return false;
            }

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);
            }

            public void onLoadResource (WebView view, String url) {

                    if (progressDialog == null) {
                        progressDialog = new ProgressDialog(SponceredDetailsActivity.this);
                        progressDialog.setMessage("Loading...");
                        progressDialog.show();
                    }

            }
            public void onPageFinished(WebView view, String url) {
                try{
                    if (progressDialog.isShowing()) {
                        progressDialog.dismiss();
                        progressDialog = null;
                    }

                }catch(Exception exception){
                    exception.printStackTrace();
                }
            }

        });

        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl(url);
    }

Call this method using this way:

startWebView(web_view,"Your Url");

Sometimes if URL is dead it will redirected and it will come to onLoadResource() before onPageFinished method. For this reason progress bar will not dismis. To solve this issue see my this Answer.

Thanks :)

End of the user session means when the browser is shut down.

Read this: http://en.wikipedia.org/wiki/HTTP_cookie#Expires_and_Max-Age

The problem is that these two queries are each returning more than one row:

select isbn from dbo.lending where (act between @fdate and @tdate) and (stat ='close')
select isbn from dbo.lending where lended_date between @fdate and @tdate

You have two choices, depending on your desired outcome. You can either replace the above queries with something that's guaranteed to return a single row (for example, by using SELECT TOP 1), OR you can switch your = to IN and return multiple rows, like this:

select * from dbo.books where isbn IN (select isbn from dbo.lending where (act between @fdate and @tdate) and (stat ='close'))

Make sure you are using this org.json: https://mvnrepository.com/artifact/org.json/json

if you are using Java 8 then you can use

import org.json.JSONArray;
import org.json.JSONObject;

JSONArray array = ...;

array.forEach(item -> {
    JSONObject obj = (JSONObject) item;
    parse(obj);
});

Just added a simple test to prove that it works:

Add the following dependency into your pom.xml file (To prove that it works, I have used the old jar which was there when I have posted this answer)

<dependency>
    <groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20160810</version>
</dependency>

And the simple test code snippet will be:

import org.json.JSONArray;
import org.json.JSONObject;

public class Test {
    public static void main(String args[]) {
        JSONArray array = new JSONArray();

        JSONObject object = new JSONObject();
        object.put("key1", "value1");

        array.put(object);

        array.forEach(item -> {
            System.out.println(item.toString());
        });
    }
}

output:

{"key1":"value1"}

In my opinion you should not load and use plugins you don't have to. This particular jQuery plugin doesn't give you anything since directly using the JavaScript sessionStorage object is exactly the same level of complexity. Nor, does the plugin provide some easier way to interact with other jQuery functionality. In addition the practice of using a plugin discourages a deep understanding of how something works. sessionStorage should be used only if its understood. If its understood, then using the jQuery plugin is actually MORE effort.

Consider using sessionStorage directly: https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Storage#sessionStorage

The two includes you mention in your comment are essential. 'does not name a type' just means there is no definition for that identifier visible to the compiler. If there are errors in the LCD library you mention, then those need to be addressed - omitting the #include will definitely not fix it!

Two notes from experience which might be helpful:

1. You need to add all #include's to the main sketch - irrespective of whether they are included via another #include.

2. If you add files to the library folder, the Arduino IDE must be restarted before those new files will be visible.

Bash allows you to place strings adjacently, and they'll just end up being glued together.

So this:

$ echo "Hello"', world!'

produces

Hello, world!

The trick is to alternate between single and double-quoted strings as required. Unfortunately, it quickly gets very messy. For example:

$ echo "I like to use" '"double quotes"' "sometimes"

produces

I like to use "double quotes" sometimes

In your example, I would do it something like this:

$ dbtable=example
$ dbload='load data local infile "'"'gfpoint.csv'"'" into '"table $dbtable FIELDS TERMINATED BY ',' ENCLOSED BY '"'"'"' LINES "'TERMINATED BY "'"'\n'"'" IGNORE 1 LINES'
$ echo $dbload

which produces the following output:

load data local infile "'gfpoint.csv'" into table example FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY "'\n'" IGNORE 1 LINES

It's difficult to see what's going on here, but I can annotate it using Unicode quotes. The following won't work in bash – it's just for illustration:

dbload=‘load data local infile "’“'gfpoint.csv'”‘" into’“table $dbtable FIELDS TERMINATED BY ',' ENCLOSED BY '”‘"’“' LINES”‘TERMINATED BY "’“'\n'”‘" IGNORE 1 LINES’

The quotes like “ ‘ ’ ” in the above will be interpreted by bash. The quotes like " ' will end up in the resulting variable.

If I give the same treatment to the earlier example, it looks like this:

$ echo“I like to use”‘"double quotes"’“sometimes”

Use one way flow syntax property binding:

<div [innerHTML]="comment"></div>

From angular docs: "Angular recognizes the value as unsafe and automatically sanitizes it, which removes the <script> tag but keeps safe content such as the <b> element."

This command is working fine for me ubuntu 16.04 LTS:

npm install --save-dev @angular/cli@latest

Use the synaptic packet manager in order to install yacc / lex. If you are feeling more comfortable doing this on the console just do:

sudo apt-get install bison flex

There are some very nice articles on the net on how to get started with those tools. I found the article from CodeProject to be quite good and helpful (see here). But you should just try and search for "introduction to lex", there are plenty of good articles showing up.

Use it like this, should work:

 <a routerLink="/Service/Sign_in"><button class="btn btn-success pull-right" > Add Customer</button></a>

You can also use router.navigateByUrl('..') like this:

<button type="button" class="btn btn-primary-outline pull-right" (click)="btnClick();"><i class="fa fa-plus"></i> Add</button>    

import { Router } from '@angular/router';

btnClick= function () {
        this.router.navigateByUrl('/user');
};

Update 1

You have to inject Router in the constructor like this:

constructor(private router: Router) { }

only then you are able to use this.router. Remember also to import RouterModule in your module.

Update 2

Now, After Angular v4 you can directly add routerLink attribute on the button (As mentioned by @mark in comment section) like below (No "'/url?" since Angular 6, when a Route in RouterModule exists) -

 <button [routerLink]="'url'"> Button Label</button>

Thanks, @guffa. The ability to do it in one line, or even within a longer statement in .NET is very handy. This VB.NET example counts the number of LineFeed characters:

Dim j As Integer = MyString.Count(Function(c As Char) c = vbLf)

j returns the number of LineFeeds in MyString.

When talking about "bad input", you should consider where the input is coming from.

Is the input entered by a user or another external system you don't control, you should expect the input to be invalid, and always validate it. It's perfectly ok to throw a checked exception in this case. Your application should 'recover' from this exception by providing an error message to the user.

If the input originates from your own system, e.g. your database, or some other parts of your application, you should be able to rely on it to be valid (it should have been validated before it got there). In this case it's perfectly ok to throw an unchecked exception like an IllegalArgumentException, which should not be caught (in general you should never catch unchecked exceptions). It is a programmer's error that the invalid value got there in the first place ;) You need to fix it.

I guess the answer you need is referenced here Python sets are not json serializable

Not all datatypes can be json serialized . I guess pickle module will serve your purpose.

Do you know the length of your prefix and suffix? In your case:

result=$(echo $string | cut -c5- | rev | cut -c3- | rev)

Or more general:

result=$(echo $string | cut -c$((${#prefix}+1))- | rev | cut -c$((${#suffix}+1))- | rev)

But the solution from Adrian Frühwirth is way cool! I didn't know about that!

Note :- Certainly in python-3x you need to use Range function It works to generate numbers on demand, standard method to use Range function to make a list of consecutive numbers is

x=list(range(10))
#"list"_will_make_all_numbers_generated_by_range_in_a_list
#number_in_range_(10)_is_an_option_you_can_change_as_you_want
print (x)
#Output_is_ [0,1,2,3,4,5,6,7,8,9]

Also if you want to make an function to generate a list of consecutive numbers by using Range function watch this code !

def  consecutive_numbers(n) :
    list=[i for i in range(n)]
    return (list)
print(consecutive_numbers(10))

Good Luck!

Actually there is another solution, but it's a workaround, that should not be done in a properly managed project. However I met a situation, where it was not possible to go down the better road :)

You can update the schame_version table, and actually change the checksum to the new one. This will cause the migration to go through, but can have other side effects.

When deploying to different environments (test, uat, prod, etc) then it might happen, that you have to update the same checksum on more environments. And when it comes to gitflow, and release branches, you can easily mix up the whole.

You can use

go build *.go 
go run *.go

both will work also you may use

go build .
go run .

There is something called 'locked reference' in excel which you can use for this, and you use $ symbols to lock a range. For your example, you would use:

=IF(B4<>"",B4/B$1,"")

This locks the 1 in B1 so that when you copy it to rows below, 1 will remain the same.

If you use $B$1, the range will not change when you copy it down a row or across a column.

In C++, you define your strings as

std::string MyString;

instead of

char MyString[20];.

While writing C++ code, you encounter some C functions which require C string as parameter.
Like below:

void IAmACFunction(int abc, float bcd, const char * cstring);

Now there is a problem. You are working with C++ and you are using std::string string variables. But this C function is asking for a C string. How do you convert your std::string to a standard C string?

Like this:

std::string MyString;
// ...
MyString = "Hello world!";
// ...
IAmACFunction(5, 2.45f, MyString.c_str());

This is what c_str() is for.

Note that, for std::wstring strings, c_str() returns a const w_char *.

You can use SQL Bulk Insert Statement

BULK INSERT TableName
FROM 'filePath'
WITH
(
  FIELDTERMINATOR = '','',
  ROWTERMINATOR = ''\n'',
  ROWS_PER_BATCH = 10000, 
  FIRSTROW = 2,
  TABLOCK
)

This answer applies when a string is manually entered, not when it's read from somewhere.

A traditional variable-width CSV is unreadable for storing data as a string variable. Especially for use inside a .py file, consider fixed-width pipe-separated data instead. Various IDEs and editors may have a plugin to format pipe-separated text into a neat table.

Using read_csv

Store the following in a utility module, e.g. util/pandas.py. An example is included in the function's docstring.

import io
import re

import pandas as pd


def read_psv(str_input: str, **kwargs) -> pd.DataFrame:
    """Read a Pandas object from a pipe-separated table contained within a string.

    Input example:
        | int_score | ext_score | eligible |
        |           | 701       | True     |
        | 221.3     | 0         | False    |
        |           | 576       | True     |
        | 300       | 600       | True     |

    The leading and trailing pipes are optional, but if one is present,
    so must be the other.

    `kwargs` are passed to `read_csv`. They must not include `sep`.

    In PyCharm, the "Pipe Table Formatter" plugin has a "Format" feature that can 
    be used to neatly format a table.

    Ref: https://stackoverflow.com/a/46471952/
    """

    substitutions = [
        ('^ *', ''),  # Remove leading spaces
        (' *$', ''),  # Remove trailing spaces
        (r' *\| *', '|'),  # Remove spaces between columns
    ]
    if all(line.lstrip().startswith('|') and line.rstrip().endswith('|') for line in str_input.strip().split('\n')):
        substitutions.extend([
            (r'^\|', ''),  # Remove redundant leading delimiter
            (r'\|$', ''),  # Remove redundant trailing delimiter
        ])
    for pattern, replacement in substitutions:
        str_input = re.sub(pattern, replacement, str_input, flags=re.MULTILINE)
    return pd.read_csv(io.StringIO(str_input), sep='|', **kwargs)

Non-working alternatives

The code below doesn't work properly because it adds an empty column on both the left and right sides.

df = pd.read_csv(io.StringIO(df_str), sep=r'\s*\|\s*', engine='python')

As for read_fwf, it doesn't actually use so many of the optional kwargs that read_csv accepts and uses. As such, it shouldn't be used at all for pipe-separated data.

As you've discovered, you can't do that. You can do:

libtest_LIBS = 

...

if HAVE_CLIENT
libtest_LIBS += libclient.la
endif

if HAVE_SERVER
libtest_LIBS += libserver.la
endif

Just use like this

 $("#sample_id").css("width", "");
 $("#sample_id").css("height", "");

Here is a bash script for newer Maven copy and paste it...

I found a very simple way that solved this problem for me and can be used or adapted:

td[row].innerHTML = price.toPrecision(price.toFixed(decimals).length

json.loads will load a json string into a python dict, json.dumps will dump a python dict to a json string, for example:

>>> json_string = '{"favorited": false, "contributors": null}'
'{"favorited": false, "contributors": null}'
>>> value = json.loads(json_string)
{u'favorited': False, u'contributors': None}
>>> json_dump = json.dumps(value)
'{"favorited": false, "contributors": null}'

So that line is incorrect since you are trying to load a python dict, and json.loads is expecting a valid json string which should have <type 'str'>.

So if you are trying to load the json, you should change what you are loading to look like the json_string above, or you should be dumping it. This is just my best guess from the given information. What is it that you are trying to accomplish?

Also you don't need to specify the u before your strings, as @Cld mentioned in the comments.

Flexible Box Layout Module - 8.1. Aligning with auto margins

Auto margins on flex items have an effect very similar to auto margins in block flow:

• During calculations of flex bases and flexible lengths, auto margins are treated as 0.

• Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Therefore you could use margin-top: auto to distribute the space between the other elements and the last element.

This will position the last element at the bottom.

p:last-of-type {
  margin-top: auto;
}

.container {
  display: flex;
  flex-direction: column;
  border: 1px solid #000;
  min-height: 200px;
  width: 100px;
}
p {
  height: 30px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-top: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
</div>

Likewise, you can also use margin-left: auto or margin-right: auto for the same alignment horizontally.

p:last-of-type {
  margin-left: auto;
}

.container {
  display: flex;
  width: 100%;
  border: 1px solid #000;
}
p {
  height: 50px;
  width: 50px;
  background-color: blue;
  margin: 5px;
}
p:last-of-type {
  margin-left: auto;
}

<div class="container">
  <p></p>
  <p></p>
  <p></p>
  <p></p>
</div>

I had an idea about using a RAM drive. It turned out that for my projects it doesn't make that much of a difference after all. But then they are pretty small still. Try it! I'd be interested in hearing how much it helped.

Aside from pandas, Apache pyarrow also provides way to transform parquet to dataframe

The code is simple, just type:

import pyarrow.parquet as pq

df = pq.read_table(source=your_file_path).to_pandas()

We use Slick Grid in Stack Exchange Data Explorer (example containing 2000 rows).

I found it outperforms jqGrid and flexigrid. It has a very complete feature set and I could not recommend it enough.

Samples of its usage are here.

You can see source samples on how it is integrated to an ASP.NET MVC app here: https://code.google.com/p/stack-exchange-data-explorer/

In Bash, using it's network wrapper through /dev/{udp,tcp}/host/port:

if : >/dev/tcp/8.8.8.8/53; then
  echo 'Internet available.'
else
  echo 'Offline.'
fi

(: is the Bash no-op, because you just want to test the connection, but not processing.)

Well, as others have stated, ambiguity in type is the issue. So the answer is no, C# doesn't let that happen because it's a strongly typed language, and it deals only with compile time known types. The compiler could have been designed to infer it as of type object, but the designers chose to avoid the extra complexity (in C# null has no type).

One alternative is

var foo = new { }; //anonymous type

Again note that you're initializing to a compile time known type, and at the end its not null, but anonymous object. It's only a few lines shorter than new object(). You can only reassign the anonymous type to foo in this one case, which may or may not be desirable.

Initializing to null with type not being known is out of question.

Unless you're using dynamic.

dynamic foo = null;
//or
var foo = (dynamic)null; //overkill

Of course it is pretty useless, unless you want to reassign values to foo variable. You lose intellisense support as well in Visual Studio.

Lastly, as others have answered, you can have a specific type declared by casting;

var foo = (T)null;

So your options are:

//initializes to non-null; I like it; cant be reassigned a value of any type
var foo = new { }; 

//initializes to non-null; can be reassigned a value of any type
var foo = new object();

//initializes to null; dangerous and finds least use; can be reassigned a value of any type
dynamic foo = null;
var foo = (dynamic)null;

//initializes to null; more conventional; can be reassigned a value of any type
object foo = null;

//initializes to null; cannot be reassigned a value of any type
var foo = (T)null;

This doesn't say how to "fix" the problem - that's already been done in other answers; it exists to draw out the details and applicable documentation references.

When using String.replaceAll or any of the applicable Matcher replacers, pay attention to the replacement string and how it is handled:

Note that backslashes (\) and dollar signs ($) in the replacement string may cause the results to be different than if it were being treated as a literal replacement string. Dollar signs may be treated as references to captured subsequences as described above, and backslashes are used to escape literal characters in the replacement string.

As pointed out by isnot2bad in a comment, Matcher.quoteReplacement may be useful here:

Returns a literal replacement String for the specified String. .. The String produced will match the sequence of characters in s treated as a literal sequence. Slashes (\) and dollar signs ($) will be given no special meaning.

This also includes the last date

$begin = new DateTime( "2015-07-03" );
$end   = new DateTime( "2015-07-09" );

for($i = $begin; $i <= $end; $i->modify('+1 day')){
    echo $i->format("Y-m-d");
}

If you dont need the last date just remove = from the condition.

lepe - That works great for me thanks! I put your code in a plugin file, then used it in conjunction with an each statement so you can have multiple pre tags and multiple "Select all" links on one page and it picks out the correct pre to highlight:

<script type="text/javascript" src="../js/jquery.selecttext.js"></script>
<script type="text/javascript">
  $(document).ready(function() { 
        $(".selectText").each(function(indx) {
                $(this).click(function() {                 
                    $('pre').eq(indx).selText().addClass("selected");
                        return false;               
                    });
        });
  });

You can't run this particular piece of code in the interactive interpreter. You'll need to save it into a file first so that you can pass the argument to it like this

$ python hello.py user338690

All tags must have enclosing tags. In my case, the hr and input elements weren't closed properly.

Parent Error was: JSX element 'div' has no corresponding closing tag, due to code below:

<hr class="my-4">
<input
  type="password"
  id="inputPassword"
  class="form-control"
  placeholder="Password"
  required
 >

Fix:

<hr class="my-4"/>
<input
 type="password"
 id="inputPassword"
 class="form-control"
 placeholder="Password"
 required
/>

The parent elements will show errors due to child element errors. Therefore, start investigating from most inner elements up to the parent ones.

Javascript doesn't have threads, but we do have workers.

Workers may be a good choice if you don't need shared objects.

Most browser implementations will actually spread workers across all cores allowing you to utilize all cores. You can see a demo of this here.

I have developed a library called task.js that makes this very easy to do.

task.js Simplified interface for getting CPU intensive code to run on all cores (node.js, and web)

A example would be

function blocking (exampleArgument) {
    // block thread
}

// turn blocking pure function into a worker task
const blockingAsync = task.wrap(blocking);

// run task on a autoscaling worker pool
blockingAsync('exampleArgumentValue').then(result => {
    // do something with result
});

This worked to move my local repo (including history) to my remote github.com repo. After creating the new empty repo at GitHub.com I use the URL in step three below and it works great.

git clone --mirror <url_of_old_repo>
cd <name_of_old_repo>
git remote add new-origin <url_of_new_repo>
git push new-origin --mirror

Html.Label - Just creates a label tag with whatever the string passed into the constructor is

Html.LabelFor - Creates a label for that specific property. This is strongly typed. By default, this will just do the name of the property (in the below example, it'll output MyProperty if that Display attribute wasn't there). Another benefit of this is you can set the display property in your model and that's what will be put here:

public class MyModel
{
    [Display(Name="My property title")
    public class MyProperty{get;set;}
}

In your view:

Html.LabelFor(x => x.MyProperty) //Outputs My property title

In the above, LabelFor will display <label for="MyProperty">My property title</label>. This works nicely so you can define in one place what the label for that property will be and have it show everywhere.

The "delete module-info.java at your Project Explorer tab" answer is the easiest and most straightforward answer, but

for those who would want a little more understanding or control of what's happening, the following alternate methods may be desirable;

• make an ever so slightly more realistic application; com.YourCompany.etc or just com.HelloWorld (Project name: com.HelloWorld and class name: HelloWorld)

or

• when creating the java project; when in the Create Java Project dialog, don't choose Finish but Next, and deselect Create module-info.java file

If you know what parameter you want to pass, take a Action<T> for the type. Example:

void LoopMethod (Action<int> code, int count) {
     for (int i = 0; i < count; i++) {
         code(i);
     }
}

If you want the parameter to be passed to your method, make the method generic:

void LoopMethod<T> (Action<T> code, int count, T paramater) {
     for (int i = 0; i < count; i++) {
         code(paramater);
     }
}

And the caller code:

Action<string> s = Console.WriteLine;
LoopMethod(s, 10, "Hello World");

Update. Your code should look like:

private void Include(IList<string> includes, Action<string> action)
{
    if (includes != null)
    {
         foreach (var include in includes)
             action(include);
    }
}

public void test()
{
    Action<string> dg = (s) => {
        _context.Cars.Include(s);
    };
    this.Include(includes, dg);
}

If you are using graph for navigation between fragments you can do this: From fragment A:

    Bundle bundle = new Bundle();
    bundle.putSerializable(KEY, yourObject);
    Navigation.findNavController(view).navigate(R.id.fragment, bundle);

To fragment B:

    Bundle bundle = getArguments();
    object = (Object) bundle.getSerializable(KEY);

Of course your object must implement Serializable

I want to add something on @Michael Laffargue's post:

jqXHR.done() is faster!

jqXHR.success() have some load time in callback and sometimes can overkill script. I find that on hard way before.

UPDATE:

Using jqXHR.done(), jqXHR.fail() and jqXHR.always() you can better manipulate with ajax request. Generaly you can define ajax in some variable or object and use that variable or object in any part of your code and get data faster. Good example:

/* Initialize some your AJAX function */
function call_ajax(attr){
    var settings=$.extend({
        call            : 'users',
        option          : 'list'
    }, attr );

    return $.ajax({
        type: "POST",
        url: "//exapmple.com//ajax.php",
        data: settings,
        cache : false
    });
}

/* .... Somewhere in your code ..... */

call_ajax({
    /* ... */
    id : 10,
    option : 'edit_user'
    change : {
          name : 'John Doe'
    }
    /* ... */
}).done(function(data){

    /* DO SOMETHING AWESOME */

});

This might help

Log.i(LOG_TAG, "shutting down executor...");
executor.shutdown();
while (true) {
                try {
                    Log.i(LOG_TAG, "Waiting for executor to terminate...");
                    if (executor.isTerminated())
                        break;
                    if (executor.awaitTermination(5000, TimeUnit.MILLISECONDS)) {
                        break;
                    }
                } catch (InterruptedException ignored) {}
            }

Updating a pull request in GitHub is as easy as committing the wanted changes into existing branch (that was used with pull request), but often it is also wanted to squash the changes into single commit:

git checkout yourbranch
git rebase -i origin/master

# Edit command names accordingly
  pick   1fc6c95 My pull request
  squash 6b2481b Hack hack - will be discarded
  squash dd1475d Also discarded

git push -f origin yourbranch

...and now the pull request contains only one commit.

if you want to add a global property, you can use:

    var styleEl = document.createElement('style'), styleSheet;
            document.head.appendChild(styleEl);
            styleSheet = styleEl.sheet;
            styleSheet.insertRule(".modal { position:absolute; bottom:auto; }", 0);

Add a GitHub repository as remote origin (replace [] with your URL):

git remote add origin [[email protected]:...]

Switch to your master branch and copy it to develop branch:

git checkout master
git checkout -b develop

Push your develop branch to the GitHub develop branch (-f means force):

git push -f origin develop:develop

Use JMockit framework. It worked for me. You don't have to write statements for mocking DBConenction.getConnection() method. Just the below code is enough.

@Mock below is mockit.Mock package

Connection jdbcConnection = Mockito.mock(Connection.class);

MockUp<DBConnection> mockUp = new MockUp<DBConnection>() {

            DBConnection singleton = new DBConnection();

            @Mock
            public DBConnection getInstance() { 
                return singleton;
            }

            @Mock
            public Connection getConnection() {
                return jdbcConnection;
            }
         };

List <String> list = new ArrayList();  
           list.add("behold"); 
           list.add("bend"); 
           list.add("bet"); 
           list.add("bear"); 
           list.add("beat"); 
           list.add("become"); 
           list.add("begin");

           List <String> listClone = new ArrayList<String>(); 
           Pattern pattern = Pattern.compile("bea",Pattern.CASE_INSENSITIVE); //incase u r not concerned about upper/lower case
           for (String string : list) {
               if(pattern.matcher(string).find()) {
                   listClone.add(string);
                   continue;
               }
           }
        System.out.println(listClone);

With Dispatcher you will need to include

using System.Windows.Threading;

Also note that if you right-click DispatcherTimer and click Resolve it should add the appropriate references.

You could just use the bound ng-model (answers[item.questID]) value itself in your ng-change method to detect if it has been checked or not.

Example:-

<input type="checkbox" ng-model="answers[item.questID]" 
     ng-change="stateChanged(item.questID)" /> <!-- Pass the specific id -->

and

$scope.stateChanged = function (qId) {
   if($scope.answers[qId]){ //If it is checked
       alert('test');
   }
}

_{I have been doing some extensive research into this and other REST paging related questions lately and thought it constructive to add some of my findings here. I'm expanding the question a bit to include thoughts on paging as well as the count as they are intimitely related.}

Headers

The paging metadata is included in the response in the form of response headers. The big benefit of this approach is that the response payload itself is just the actual data requestor was asking for. Making processing the response easier for clients that are not interested in the paging information.

There are a bunch of (standard and custom) headers used in the wild to return paging related information, including the total count.

X-Total-Count

X-Total-Count: 234

This is used in some APIs I found in the wild. There are also NPM packages for adding support for this header to e.g. Loopback. Some articles recommend setting this header as well.

It is often used in combination with the Link header, which is a pretty good solution for paging, but lacks the total count information.

Link

Link: </TheBook/chapter2>;
      rel="previous"; title*=UTF-8'de'letztes%20Kapitel,
      </TheBook/chapter4>;
      rel="next"; title*=UTF-8'de'n%c3%a4chstes%20Kapitel

I feel, from reading a lot on this subject, that the general consensus is to use the Link header to provide paging links to clients using rel=next, rel=previous etc. The problem with this is that it lacks the information of how many total records there are, which is why many APIs combine this with the X-Total-Count header.

Alternatively, some APIs and e.g. the JsonApi standard, use the Link format, but add the information in a response envelope instead of to a header. This simplifies access to the metadata (and creates a place to add the total count information) at the expense of increasing complexity of accessing the actual data itself (by adding an envelope).

Content-Range

Content-Range: items 0-49/234

Promoted by a blog article named Range header, I choose you (for pagination)!. The author makes a strong case for using the Range and Content-Range headers for pagination. When we carefully read the RFC on these headers, we find that extending their meaning beyond ranges of bytes was actually anticipated by the RFC and is explicitly permitted. When used in the context of items instead of bytes, the Range header actually gives us a way to both request a certain range of items and indicate what range of the total result the response items relate to. This header also gives a great way to show the total count. And it is a true standard that mostly maps one-to-one to paging. It is also used in the wild.

Envelope

Many APIs, including the one from our favorite Q&A website use an envelope, a wrapper around the data that is used to add meta information about the data. Also, OData and JsonApi standards both use a response envelope.

The big downside to this (imho) is that processing the response data becomes more complex as the actual data has to be found somewhere in the envelope. Also there are many different formats for that envelope and you have to use the right one. It is telling that the response envelopes from OData and JsonApi are wildly different, with OData mixing in metadata at multiple points in the response.

Separate endpoint

I think this has been covered enough in the other answers. I did not investigate this much because I agree with the comments that this is confusing as you now have multiple types of endpoints. I think it's nicest if every endpoint represents a (collection of) resource(s).

Further thoughts

We don't only have to communicate the paging meta information related to the response, but also allow the client to request specific pages/ranges. It is interesting to also look at this aspect to end up with a coherent solution. Here too we can use headers (the Range header seems very suitable), or other mechanisms such as query parameters. Some people advocate treating pages of results as separate resources, which may make sense in some use cases (e.g. /books/231/pages/52. I ended up selecting a wild range of frequently used request parameters such as pagesize, page[size] and limit etc in addition to supporting the Range header (and as request parameter as well).

There are a couple of things that need to be adjusted in your layout:

1. You are nesting col elements within form-group elements. This should be the other way around (the form-group should be within the col-sm-xx element).

2. You should always use a row div for each new "row" in your design. In your case, you would need at least 5 rows (Username, Password and co, Title/First/Last name, email, Language). Otherwise, your problematic .col-sm-12 is still on the same row with the above 3 .col-sm-4 resulting in a total of columns greater than 12, and causing the overlap problem.

Here is a fixed demo.

And an excerpt of what the problematic section HTML should become:

<fieldset>
    <legend>Personal Information</legend>
    <div class='row'>
        <div class='col-sm-4'>    
            <div class='form-group'>
                <label for="user_title">Title</label>
                <input class="form-control" id="user_title" name="user[title]" size="30" type="text" />
            </div>
        </div>
        <div class='col-sm-4'>
            <div class='form-group'>
                <label for="user_firstname">First name</label>
                <input class="form-control" id="user_firstname" name="user[firstname]" required="true" size="30" type="text" />
            </div>
        </div>
        <div class='col-sm-4'>
            <div class='form-group'>
                <label for="user_lastname">Last name</label>
                <input class="form-control" id="user_lastname" name="user[lastname]" required="true" size="30" type="text" />
            </div>
        </div>
    </div>
    <div class='row'>
        <div class='col-sm-12'>
            <div class='form-group'>

                <label for="user_email">Email</label>
                <input class="form-control required email" id="user_email" name="user[email]" required="true" size="30" type="text" />
            </div>
        </div>
    </div>
</fieldset>

Using this and your solution, you can handle all browsers except Firefox, which at this point I think still requires a javascript solution.

I gave up and inserted a simple jQuery code as below. This will add a tr after every tr, if you have so many trs like me. Demo: https://jsfiddle.net/acf9sph6/

<table>
  <tbody>
     <tr class="my-tr">
        <td>one line</td>
     </tr>
     <tr class="my-tr">
        <td>one line</td>
     </tr>
     <tr class="my-tr">
        <td>one line</td>
     </tr>
  </tbody>
</table>
<script>
$(function () {
       $("tr.my-tr").after('<tr class="tr-spacer"/>');
});
</script>
<style>
.tr-spacer
{
    height: 20px;
}
</style>

Additional comment. Yes this works:

    sed 's/\"//g' infile.txt  > outfile.txt

(however with batch gnu sed, will just print to screen)

In batch scripting (GNU SED), this was needed:

    sed 's/\x22//g' infile.txt  > outfile.txt

I think the problem is that you load isfar data.frame but you overwrite it by value returned by load.

Try either:

load("C:/Users/isfar.RData") 
head(isfar)

Or more general way

load("C:/Users/isfar.RData", ex <- new.env())
ls.str(ex) 

An auto-updated column is automatically updated to the current timestamp when the value of any other column in the row is changed from its current value. An auto-updated column remains unchanged if all other columns are set to their current values.

To explain it let's imagine you have only one row:

-------------------------------
| price | updated_at          |
-------------------------------
|  2    | 2018-02-26 16:16:17 |
-------------------------------

Now, if you run the following update column:

 update my_table
 set price = 2

it will not change the value of updated_at, since price value wasn't actually changed (it was already 2).

But if you have another row with price value other than 2, then the updated_at value of that row (with price <> 3) will be updated to CURRENT_TIMESTAMP.

The answer of Mark Byers is the optimal in this situation. Though in more complex situations you can take the select query that returns rowids and calculated values and attach it to the update query like this:

with t as (
  -- Any generic query which returns rowid and corresponding calculated values
  select t1.id as rowid, f(t2, t2) as calculatedvalue
  from table1 as t1
  join table2 as t2 on t2.referenceid = t1.id
)
update table1
set value = t.calculatedvalue
from t
where id = t.rowid

This approach lets you develop and test your select query and in two steps convert it to the update query.

So in your case the result query will be:

Note that column aliases are mandatory otherwise PostgreSQL will complain about the ambiguity of the column names.

Maybe you coul'd use UTF8 bold chars.

It works on Chromium 80.0, I don't know on other browsers...

I don't know that regex would handle something like that very well. Try something like this

line = line.Trim();
if(line.StartsWith("for") && line.EndsWith(";")){
    //your code here
}

JavaScript, as defined in your question, can't directly work with MySql. This is because it isn't running on the same computer.

JavaScript runs on the client side (in the browser), and databases usually exist on the server side. You'll probably need to use an intermediate server-side language (like PHP, Java, .Net, or a server-side JavaScript stack like Node.js) to do the query.

Here's a tutorial on how to write some code that would bind PHP, JavaScript, and MySql together, with code running both in the browser, and on a server:

http://www.w3schools.com/php/php_ajax_database.asp

And here's the code from that page. It doesn't exactly match your scenario (it does a query, and doesn't store data in the DB), but it might help you start to understand the types of interactions you'll need in order to make this work.

In particular, pay attention to these bits of code from that article.

Bits of Javascript:

xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();

Bits of PHP code:

mysql_select_db("ajax_demo", $con);
$result = mysql_query($sql);
// ...
$row = mysql_fetch_array($result)
mysql_close($con);

Also, after you get a handle on how this sort of code works, I suggest you use the jQuery JavaScript library to do your AJAX calls. It is much cleaner and easier to deal with than the built-in AJAX support, and you won't have to write browser-specific code, as jQuery has cross-browser support built in. Here's the page for the jQuery AJAX API documentation.

The code from the article

HTML/Javascript code:

<html>
<head>
<script type="text/javascript">
function showUser(str)
{
if (str=="")
  {
  document.getElementById("txtHint").innerHTML="";
  return;
  } 
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}
</script>

mysql_close($con);

swift 4.0

let stringNumber = "123"
let number = Int(stringNumber) //here number is of type "Int?"


//using Forced Unwrapping

if number != nil {         
 //string is converted to Int
}

you could also use Optional Binding other than forced binding.

eg:

  if let number = Int(stringNumber) { 
   // number is of type Int 
  }

You didn't publish your code, and I suspect you do something wrong. it is possible to change the size by assigning width and height attributes using numbers:

canvasNode.width  = 200; // in pixels
canvasNode.height = 100; // in pixels

At least it works for me. Make sure you don't assign strings (e.g., "2cm", "3in", or "2.5px"), and don't mess with styles.

Actually this is a publicly available knowledge — you can read all about it in the HTML canvas spec — it is very small and unusually informative. This is the whole DOM interface:

interface HTMLCanvasElement : HTMLElement {
           attribute unsigned long width;
           attribute unsigned long height;

  DOMString toDataURL();
  DOMString toDataURL(in DOMString type, [Variadic] in any args);

  DOMObject getContext(in DOMString contextId);
};

As you can see it defines 2 attributes width and height, and both of them are unsigned long.

I've managed to find a CSS workaround to preventing bouncing of the viewport. The key was to wrap the content in 3 divs with -webkit-touch-overflow:scroll applied to them. The final div should have a min-height of 101%. In addition, you should explicitly set fixed widths/heights on the body tag representing the size of your device. I've added a red background on the body to demonstrate that it is the content that is now bouncing and not the mobile safari viewport.

Source code below and here is a plunker (this has been tested on iOS7 GM too). http://embed.plnkr.co/NCOFoY/preview

If you intend to run this as a full-screen app on iPhone 5, modify the height to 1136px (when apple-mobile-web-app-status-bar-style is set to 'black-translucent' or 1096px when set to 'black'). 920x is the height of the viewport once the chrome of mobile safari has been taken into account).

I had challenge with users innocently entering € and some using double quotes to define their content. I tweaked a couple of answers from this page and others to finally define my small little work-around

$products = array($ofDirtyArray);
if($products !=null) {
    header("Content-type: application/json");
    header('Content-Type: charset=utf-8');
    array_walk_recursive($products, function(&$val) {
        $val = html_entity_decode(htmlentities($val, ENT_QUOTES, "UTF-8"));
    });
    echo json_encode($products,  JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES | JSON_NUMERIC_CHECK);
}

I hope it helps someone/someone improves it.

My personal opinion is that it is a waste of time. I believe that the visual clutter and added verbosity is not worth it.

I have never been in a situation where I have reassigned (remember, this does not make objects immutable, all it means is that you can't reassign another reference to a variable) a variable in error.

But, of course, it's all personal preference ;-)

Or you could configure mapper as :

// custom configuration for lazy loading

public static class HibernateLazyInitializerSerializer extends JsonSerializer<JavassistLazyInitializer> {

    @Override
    public void serialize(JavassistLazyInitializer initializer, JsonGenerator jsonGenerator,
            SerializerProvider serializerProvider)
            throws IOException, JsonProcessingException {
        jsonGenerator.writeNull();
    }
}

and configure mapper:

    mapper = new JacksonMapper();
    SimpleModule simpleModule = new SimpleModule(
            "SimpleModule", new Version(1,0,0,null)
    );
    simpleModule.addSerializer(
            JavassistLazyInitializer.class,
            new HibernateLazyInitializerSerializer()
    );
    mapper.registerModule(simpleModule);

As the other answers note, you can add a background-color to a <span> around your text to get this to work.

In the case where you have line-height though, you will see gaps. To fix this you can add a box-shadow with a little bit of grow to your span. You will also want box-decoration-break: clone; for FireFox to render it properly.

EDIT: If you're getting issues in IE11 with the box-shadow, try adding an outline: 1px solid [color]; as well for IE only.

Here's what it looks like in action:

.container {_x000D_
  margin: 0 auto;_x000D_
  width: 400px;_x000D_
  padding: 10px;_x000D_
  border: 1px solid black;_x000D_
}_x000D_
_x000D_
h2 {_x000D_
  margin: 0;_x000D_
  padding: 0;_x000D_
  font-family: Verdana, sans-serif;_x000D_
  text-transform: uppercase;_x000D_
  line-height: 1.5;_x000D_
  text-align: center;_x000D_
  font-size: 40px;_x000D_
}_x000D_
_x000D_
h2 > span {_x000D_
  background-color: #D32;_x000D_
  color: #FFF;_x000D_
  box-shadow: -10px 0px 0 7px #D32,_x000D_
    10px 0px 0 7px #D32,_x000D_
    0 0 0 7px #D32;_x000D_
  box-decoration-break: clone;_x000D_
}

<div class="container">_x000D_
    <h2><span>A HEADLINE WITH BACKGROUND-COLOR PLUS BOX-SHADOW :3</span></h2>_x000D_
</div>

Just for an addition reference to the above answers. I can not use dpkg -L to find the correct path for cuda. See the results I got from dpkg -L

$ dpkg -L cuda
/.
/usr
/usr/share
/usr/share/doc
/usr/share/doc/cuda
/usr/share/doc/cuda/copyright
/usr/share/doc/cuda/changelog.Debian.gz

the correct path is /usr/local/cuda

$ ll /usr/local | grep cuda

lrwxrwxrwx  1 root root    8 Oct 20 18:45 cuda -> cuda-9.0/

drwxr-xr-x 15 root root 4096 Oct 20 18:44 cuda-9.0/

Btw, I did install cuda by the command of

dpkg -i xx_cuda_xxx.deb

I think that they should perform generally the same, but there are some differences. START is generally used to start applications or to start the default application for a given file type. That way if you START http://mywebsite.com it doesn't do START iexplore.exe http://mywebsite.com.

START myworddoc.docx would start Microsoft Word and open myworddoc.docx.CALL myworddoc.docx does the same thing... however START provides more options for the window state and things of that nature. It also allows process priority and affinity to be set.

In short, given the additional options provided by start, it should be your tool of choice.

START ["title"] [/D path] [/I] [/MIN] [/MAX] [/SEPARATE | /SHARED]
  [/LOW | /NORMAL | /HIGH | /REALTIME | /ABOVENORMAL | /BELOWNORMAL]
  [/NODE <NUMA node>] [/AFFINITY <hex affinity mask>] [/WAIT] [/B]
  [command/program] [parameters]

"title"     Title to display in window title bar.
path        Starting directory.
B           Start application without creating a new window. The
            application has ^C handling ignored. Unless the application
            enables ^C processing, ^Break is the only way to interrupt
            the application.
I           The new environment will be the original environment passed
            to the cmd.exe and not the current environment.
MIN         Start window minimized.
MAX         Start window maximized.
SEPARATE    Start 16-bit Windows program in separate memory space.
SHARED      Start 16-bit Windows program in shared memory space.
LOW         Start application in the IDLE priority class.
NORMAL      Start application in the NORMAL priority class.
HIGH        Start application in the HIGH priority class.
REALTIME    Start application in the REALTIME priority class.
ABOVENORMAL Start application in the ABOVENORMAL priority class.
BELOWNORMAL Start application in the BELOWNORMAL priority class.
NODE        Specifies the preferred Non-Uniform Memory Architecture (NUMA)
            node as a decimal integer.
AFFINITY    Specifies the processor affinity mask as a hexadecimal number.
            The process is restricted to running on these processors.

            The affinity mask is interpreted differently when /AFFINITY and
            /NODE are combined.  Specify the affinity mask as if the NUMA
            node's processor mask is right shifted to begin at bit zero.
            The process is restricted to running on those processors in
            common between the specified affinity mask and the NUMA node.
            If no processors are in common, the process is restricted to
            running on the specified NUMA node.
WAIT        Start application and wait for it to terminate.

Use BindingFlags.NonPublic and BindingFlags.Instance flags

Using BalusC's suggestion of implementing Collection i can now hide my primefaces p:dataTable using not empty operator on my dataModel that extends javax.faces.model.ListDataModel

Code sample:

import java.io.Serializable;
import java.util.Collection;
import java.util.List;
import javax.faces.model.ListDataModel;
import org.primefaces.model.SelectableDataModel;

public class EntityDataModel extends ListDataModel<Entity> implements
        Collection<Entity>, SelectableDataModel<Entity>, Serializable {

    public EntityDataModel(List<Entity> data) { super(data); }

    @Override
    public Entity getRowData(String rowKey) {
        // In a real app, a more efficient way like a query by rowKey should be
        // implemented to deal with huge data
        List<Entity> entitys = (List<Entity>) getWrappedData();
        for (Entity entity : entitys) {
            if (Integer.toString(entity.getId()).equals(rowKey)) return entity;
        }
        return null;
    }

    @Override
    public Object getRowKey(Entity entity) {
        return entity.getId();
    }

    @Override
    public boolean isEmpty() {
        List<Entity> entity = (List<Entity>) getWrappedData();
        return (entity == null) || entity.isEmpty();
    }
    // ... other not implemented methods of Collection...

If you are using Eclipse you can move files to and from the SD Card through the Android Perspective (it is called DDMS in Eclipse). Just select the Emulator in the left part of the screen and then choose the File Explorer tab. Above the list with your files should be two symbols, one with an arrow pointing at a phone, clicking this will allow you to choose a file to move to phone memory.

make sure your ftp transfers are in binary mode.

I don't think you can. I always go with height and width.

textarea{
width:400px;
height:100px;
}

the nice thing about doing it the CSS way is that you can completely style it up. Now you can add things like:

textarea{
width:400px;
height:100px;
border:1px solid #000000;
background-color:#CCCCCC;
}

A callback lets you pass executable code as an argument to other code. In C and C++ this is implemented as a function pointer. In .NET you would use a delegate to manage function pointers.

A few uses include error signaling and controlling whether a function acts or not.

Later versions of Safari allow you to Disable Cross-Origin Restrictions. Just enable the developer menu from Preferences >> Advanced, and select "Disable Cross-Origin Restrictions" from the develop menu.

If you want local only, then you only need to enable the developer menu, and select "Disable local file restrictions" from the develop menu.

Before assigning a new column, if you have indexed data, you need to sort the index. At least in my case I had to:

data.set_index(['index_column'], inplace=True)
"if index is unsorted, assignment of a new column will fail"        
data.sort_index(inplace = True)
data.loc['index_value1', 'column_y'] = np.random.randn(data.loc['index_value1', 'column_x'].shape[0])

Use subshell:

echo "$(echo -n 'hello'; cat filename)" > filename

Unfortunately, command substitution will remove newlines at the end of file. So as to keep them one can use:

echo -n "hello" | cat - filename > /tmp/filename.tmp
mv /tmp/filename.tmp filename

Neither grouping nor command substitution is needed.

This method uses the 'C' memset function, and is very fast (avoids a char-by-char loop).

const uint size = 65546;
char* msg = new char[size];
memset(reinterpret_cast<void*>(msg), 0, size);

Copy your XML schema here & get the JSON schema code to the online tools which are available to generate JSON schema from XML schema.

To put it all together, this is what it should look like:

In the controller:

List<Fund> fundList = db.Funds.ToList();
ViewBag.Funds = fundList;

Then in the view:

@foreach (var item in ViewBag.Funds)
{
    <span> @item.FundName </span>
}

I meet the same problem today with OkHttp client to GET a https based url. It was caused by Https protocol version and Cipher method mismatch between server side and client side.

openssl>s_client -connect your_website.com:443 -showcerts

You will get many detail info, the key info is listed as follows:

SSL-Session:
    Protocol  : TLSv1
    Cipher    : RC4-SHA

@Test()
public void testHttpsByOkHttp() {
    ConnectionSpec spec = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
            .tlsVersions(TlsVersion.TLS_1_0) //protocol version
            .cipherSuites(
                    CipherSuite.TLS_RSA_WITH_RC4_128_SHA, //cipher method
                    CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,
                    CipherSuite.TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,
                    CipherSuite.TLS_DHE_RSA_WITH_AES_128_GCM_SHA256)
            .build();

    OkHttpClient client = new OkHttpClient();
    client.setConnectionSpecs(Collections.singletonList(spec));
    Request request = new Request.Builder().url("https://your_website.com/").build();
    try {
        Response response = client.newCall(request).execute();
        if(response.isSuccessful()){
            logger.debug("result= {}", response.body().string());
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}

This will get what we want.

Also, if you need to format telephone number on output only, you can use a custom filter like this one:

angular.module('ng').filter('tel', function () {
    return function (tel) {
        if (!tel) { return ''; }

        var value = tel.toString().trim().replace(/^\+/, '');

        if (value.match(/[^0-9]/)) {
            return tel;
        }

        var country, city, number;

        switch (value.length) {
            case 10: // +1PPP####### -> C (PPP) ###-####
                country = 1;
                city = value.slice(0, 3);
                number = value.slice(3);
                break;

            case 11: // +CPPP####### -> CCC (PP) ###-####
                country = value[0];
                city = value.slice(1, 4);
                number = value.slice(4);
                break;

            case 12: // +CCCPP####### -> CCC (PP) ###-####
                country = value.slice(0, 3);
                city = value.slice(3, 5);
                number = value.slice(5);
                break;

            default:
                return tel;
        }

        if (country == 1) {
            country = "";
        }

        number = number.slice(0, 3) + '-' + number.slice(3);

        return (country + " (" + city + ") " + number).trim();
    };
});

Then you can use this filter in your template:

{{ phoneNumber | tel }}
<span ng-bind="phoneNumber | tel"></span>

You can use the following stored procedure to fetch , values.

IF  EXISTS (SELECT * FROM sys.objects 
WHERE object_id = OBJECT_ID(N'[dbo].[sp_parsedata]') AND type in (N'P', N'PC'))
    DROP PROCEDURE [dbo].[sp_parsedata]
GO
create procedure sp_parsedata
(@cid integer,@st varchar(1000))
as
  declare @coid integer
  declare @c integer
  declare @c1 integer
  select @c1=len(@st) - len(replace(@st, ',', ''))
  set @c=0
  delete from table1 where complainid=@cid;
  while (@c<=@c1)
    begin
      if (@c<@c1) 
        begin
          select @coid=cast(replace(left(@st,CHARINDEX(',',@st,1)),',','') as integer)
          select @st=SUBSTRING(@st,CHARINDEX(',',@st,1)+1,LEN(@st))
        end
      else
        begin
          select @coid=cast(@st as integer)
        end
      insert into table1(complainid,courtid) values(@cid,@coid)
      set @c=@c+1
    end

This can be done using driver.execute_script():-

driver.execute_script("document.getElementById('myelementid').scrollIntoView();")

It sounds like you are on the right track with your directory structure. When you compile the dependent code, specify the -classpath argument of javac. Use the parent directory of the com directory, where com, in turn, contains company/thing/YourClass.class

So, when you do this:

javac -classpath <parent> client.java

The <parent> should be referring to the parent of com. If you are in com, it would be ../.

To see the window height while (or after) it is resized, try it:

$(window).resize(function() {

In case someone wants to make use of sorting at a critical part of their programs here's a performance comparison for the different proposals:

import numpy as np
table = np.random.rand(5000, 10)

%timeit table.view('f8,f8,f8,f8,f8,f8,f8,f8,f8,f8').sort(order=['f9'], axis=0)
1000 loops, best of 3: 1.88 ms per loop

%timeit table[table[:,9].argsort()]
10000 loops, best of 3: 180 µs per loop

import pandas as pd
df = pd.DataFrame(table)
%timeit df.sort_values(9, ascending=True)
1000 loops, best of 3: 400 µs per loop

So, it looks like indexing with argsort is the quickest method so far...

A process is a collection of code, memory, data and other resources. A thread is a sequence of code that is executed within the scope of the process. You can (usually) have multiple threads executing concurrently within the same process.

To my mind the case for a PT (as @Nathan Fisher) is a 'no brainer', but I would add a column to facilitate ordering by rank (up or down):

OPS is entered as VALUES (Sum of) twice so I have renamed the column labels to make clearer which is which. The PT is in a different sheet from the data but could be in the same sheet.

Rank is set with a right click on a data point selected in that column and Show Values As... and Rank Largest to Smallest (there are other options) with the Base field as Player and the filter is a Value Filters, Top 10... one:

Once in a PT the power of that feature can very easily be applied to view the data in many other ways, with no change of formula (there isn't one!).

In the case of a tie for the last position included in the filter both results are included (Top 5 would show six or more results). A tie for top rank between just two players would show as 1 1 3 4 5 for Top 5.

You could use TimeZoneInfo class

The TimeZone class recognizes local time zone, and can convert times between Coordinated Universal Time (UTC) and local time. A TimeZoneInfo object can represent any time zone, and methods of the TimeZoneInfo class can be used to convert the time in one time zone to the corresponding time in any other time zone. The members of the TimeZoneInfo class support the following operations:

1. Retrieving a time zone that is already defined by the operating system.

2. Enumerating the time zones that are available on a system.

3. Converting times between different time zones.

4. Creating a new time zone that is not already defined by the operating system.

   Serializing a time zone for later retrieval.

All answers here are still using the FormData API. It is like a "multipart/form-data" upload without a form. You can also upload the file directly as content inside the body of the POST request using xmlHttpRequest like this:

var xmlHttpRequest = new XMLHttpRequest();

var file = ...file handle...
var fileName = ...file name...
var target = ...target...
var mimeType = ...mime type...

xmlHttpRequest.open('POST', target, true);
xmlHttpRequest.setRequestHeader('Content-Type', mimeType);
xmlHttpRequest.setRequestHeader('Content-Disposition', 'attachment; filename="' + fileName + '"');
xmlHttpRequest.send(file);

Content-Type and Content-Disposition headers are used for explaining what we are sending (mime-type and file name).

I posted similar answer also here.

The link_tag() helper is clearly the way to do this. Put your css where it usually belongs, in site_root/css/ and then use the helper:

From The CodeIgniter docs...

echo link_tag('css/mystyles.css');

Output

<link href="http://example.com/css/mystyles.css" rel="stylesheet" type="text/css" />

This worked for me:

export function modalSave(name,id){
  console.log('modalChanges action ' + name+id);  

  return {
    type: 'EDIT',
    payload: new Promise((resolve, reject) => {
      const value = {
        Name: name,
        ID: id,
      } 

      axios({
        method: 'put',
        url: 'http://localhost:53203/api/values',
        data: value,
        config: { headers: {'Content-Type': 'multipart/form-data' }}
      })
       .then(function (response) {
         if (response.status === 200) {
           console.log("Update Success");
           resolve();
         }
       })
       .catch(function (response) {
         console.log(response);
         resolve();
       });
    })
  };
}

JSON (= JavaScript Object Notation), is a lightweight and fast mechanism to convert Javascript objects into a string and vice versa.

Since Javascripts objects consists of key/value pairs its very easy to use and access JSON that way.

So if we have an object:

var myObj = {
    foo:   'bar',
    base:  'ball',
    deep:  {
       java:  'script'
    }
};

We can convert that into a string by calling window.JSON.stringify(myObj); with the result of "{"foo":"bar","base":"ball","deep":{"java":"script"}}".

The other way around, we would call window.JSON.parse("a json string like the above");.

JSON.parse() returns a javascript object/array on success.

alert(myObj.deep.java);  // 'script'

window.JSON is not natively available in all browser. Some "older" browser need a little javascript plugin which offers the above mentioned functionality. Check http://www.json.org for further information.

There are some nice regexes for replacing HTML with BBCode here. For all you nay-sayers, note that he's not trying to fully parse HTML, just to sanitize it. He can probably afford to kill off tags that his simple "parser" can't understand.

Ok, Denizens. So I have accepted the command line length limits as gospel for quite some time. So, what to do with one's assumptions? Naturally- check them.

I have a Fedora 22 machine at my disposal (meaning: Linux with bash4). I have created a directory with 500,000 inodes (files) in it each of 18 characters long. The command line length is 9,500,000 characters. Created thus:

seq 1 500000 | while read digit; do
    touch $(printf "abigfilename%06d\n" $digit);
done

And we note:

$ getconf ARG_MAX
2097152

Note however I can do this:

$ echo * > /dev/null

But this fails:

$ /bin/echo * > /dev/null
bash: /bin/echo: Argument list too long

I can run a for loop:

$ for f in *; do :; done

which is another shell builtin.

Careful reading of the documentation for ARG_MAX states, Maximum length of argument to the exec functions. This means: Without calling exec, there is no ARG_MAX limitation. So it would explain why shell builtins are not restricted by ARG_MAX.

And indeed, I can ls my directory if my argument list is 109948 files long, or about 2,089,000 characters (give or take). Once I add one more 18-character filename file, though, then I get an Argument list too long error. So ARG_MAX is working as advertised: the exec is failing with more than ARG_MAX characters on the argument list- including, it should be noted, the environment data.

Go with the following if you really want to use a loop. Nobody has actually answered how to feed data in a loop:

def plot(data):
    fig = plt.figure(figsize=(100, 100))
    for idx, k in enumerate(data.keys(), 1):
        x, y = data[k].keys(), data[k].values
        plt.subplot(63, 10, idx)
        plt.bar(x, y)  
    plt.show()

I think you set the marquee width related to 5 images total width. It works fine

ex: <marquee style="width:700px"></marquee>

My reason for researching this question was from the perspective, is in what way are they compatible. Latin1 charset (iso-8859) is 100% compatible to be stored in a utf8 datastore. All ascii & extended-ascii chars will be stored as single-byte.

Going the other way, from utf8 to Latin1 charset may or may not work. If there are any 2-byte chars (chars beyond extended-ascii 255) they will not store in a Latin1 datastore.

The browser's plugin controls those settings, so you can't force it. However, you can do a simple <a href="whatver.pdf"> instead of <a href="whatever.pdf" target="_blank">.

A correct way to do basic auth in Python3 urllib.request with certificate validation follows.

Note that certifi is not mandatory. You can use your OS bundle (likely *nix only) or distribute Mozilla's CA Bundle yourself. Or if the hosts you communicate with are just a few, concatenate CA file yourself from the hosts' CAs, which can reduce the risk of MitM attack caused by another corrupt CA.

#!/usr/bin/env python3


import urllib.request
import ssl

import certifi


context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
context.verify_mode = ssl.CERT_REQUIRED
context.load_verify_locations(certifi.where())
httpsHandler = urllib.request.HTTPSHandler(context = context)

manager = urllib.request.HTTPPasswordMgrWithDefaultRealm()
manager.add_password(None, 'https://domain.com/', 'username', 'password')
authHandler = urllib.request.HTTPBasicAuthHandler(manager)

opener = urllib.request.build_opener(httpsHandler, authHandler)

# Used globally for all urllib.request requests.
# If it doesn't fit your design, use opener directly.
urllib.request.install_opener(opener)

response = urllib.request.urlopen('https://domain.com/some/path')
print(response.read())

The onBlur event is fired when you have moved away from an object without necessarily having changed its value.

The onChange event is only called when you have changed the value of the field and it loses focus.

You might want to take a look at quirksmode's intro to events. This is a great place to get info on what's going on in your browser when you interact with it. His book is good too.

Had the same problem in Eclipse. For some reason I didn't have the servlet.jar file in my build path. What I wound up doing was copying a "lib" folder from another project of mine to the project I was working on, then manually going into that folder and adding the servlet.jar file to the build path (option shows up when you right-click on the file in the project explorer).

Paste it: chrome://settings/content

Go to "Javascript" section and disable it.

Changing this line:

var doc = new jsPDF('L', 'px', [w, h]);
var doc = new jsPDF('L', 'pt', [w, h]);

To fix the dimensions.

Your command is completely incorrect. The output format is not rawvideo and you don't need the bitstream filter h264_mp4toannexb which is used when you want to convert the h264 contained in an mp4 to the Annex B format used by MPEG-TS for example. What you want to use instead is the aac_adtstoasc for the AAC streams.

ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

Your comparison function is not even wrong.

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

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

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

See StrictWeakOrdering which describes the properties the function must meet.

Could you use FILE* instead, and the measure the performance you've gained? A couple of options is to use fwrite/write instead of fstream:

#include <stdio.h>

int main ()
{
  FILE * pFile;
  char buffer[] = { 'x' , 'y' , 'z' };
  pFile = fopen ( "myfile.bin" , "w+b" );
  fwrite (buffer , 1 , sizeof(buffer) , pFile );
  fclose (pFile);
  return 0;
}

If you decide to use write, try something similar:

#include <unistd.h>
#include <fcntl.h>

int main(void)
{
    int filedesc = open("testfile.txt", O_WRONLY | O_APPEND);

    if (filedesc < 0) {
        return -1;
    }

    if (write(filedesc, "This will be output to testfile.txt\n", 36) != 36) {
        write(2, "There was an error writing to testfile.txt\n", 43);
        return -1;
    }

    return 0;
}

I would also advice you to look into memory map. That may be your answer. Once I had to process a 20GB file in other to store it in the database, and the file as not even opening. So the solution as to utilize moemory map. I did that in Python though.

=OFFSET(NameList!$A$2:$A$200,MATCH(INDIRECT("FillData!"&ADDRESS(ROW(),COLUMN(),4))&"*",NameList!$A$2:$A$200,0)-1,0,COUNTIF($A$2:$A$200,INDIRECT("FillData!"&ADDRESS(ROW(),COLUMN(),4))&"*"),1)

1. Create sheet name as Namelist. In column A fill list of data.

2. Create another sheet name as FillData for making data validation list as you want.

3. Type first alphabet and select, drop down menu will appear depend on you type.

Although it's too late , But here is my experience .

Whenever you get your maven project from a source controller or just copying your project from one machine to another , you need to update the dependencies .

For this Right-click on Project on project explorer -> Maven -> Update Project.

Please consider checking the "Force update of snapshot/releases" checkbox.

If you have not your dependencies in m2/repository then you need internet connection to get from the remote maven repository.

In case you have get from the source controller and you have not any unit test , It's probably your test folder does not include in the source controller in the first place , so you don't have those in the new repository.so you need to create those folders manually.

I have had both these cases .

You could give Benchmark.js a try. It supports many platforms among them also node.js.

Once again the problem with unit-testing comes from manually creating objects using new operator. Consider passing already created Second instead:

class First {

  private Second second;

  public First(int num, Second second) {
    this.second = second;
    this.num = num;
  }

  // some other methods...
}

I know this might mean major rewrite of your API, but there is no other way. Also this class doesn't have any sense:

Mockito.when(new Second(any(String.class).thenReturn(null)));

First of all Mockito can only mock methods, not constructors. Secondly, even if you could mock constructor, you are mocking constructor of just created object and never really doing anything with that object.

In case of MySQL or SQLite the correct keyword is IFNULL (not ISNULL).

 SELECT iar.Description, 
      IFNULL(iai.Quantity,0) as Quantity, 
      IFNULL(iai.Quantity * rpl.RegularPrice,0) as 'Retail', 
      iar.Compliance 
    FROM InventoryAdjustmentReason iar
    LEFT OUTER JOIN InventoryAdjustmentItem iai  on (iar.Id = iai.InventoryAdjustmentReasonId)
    LEFT OUTER JOIN Item i on (i.Id = iai.ItemId)
    LEFT OUTER JOIN ReportPriceLookup rpl on (rpl.SkuNumber = i.SkuNo)
WHERE iar.StoreUse = 'yes'

Take a table with class name column-bordered-table then add this below css.This will work with bootstrap table too

.column-bordered-table thead td {
    border-left: 1px solid #c3c3c3;
    border-right: 1px solid #c3c3c3;
}

.column-bordered-table td {
    border-left: 1px solid #c3c3c3;
    border-right: 1px solid #c3c3c3;
}

.column-bordered-table tfoot tr {
    border-top: 1px solid #c3c3c3;
    border-bottom: 1px solid #c3c3c3;
}

see the output below

Ran into the same thing trying to install brew's python3 under Mac OS! The issue here is that in Mac OS, homebrew puts the "real" python a whole layer deeper than you think. You would think from the homebrew output that

$ echo $PYTHONHOME
/usr/local/Cellar/python3/3.6.2/
$ echo $PYTHONPATH
/usr/local/Cellar/python3/3.6.2/bin

would be correct, but invoking $PYTHONPATH/python3 immediately crashes with the abort 6 "can't find encodings." This is because although that $PYTHONHOME looks like a complete installation, having a bin, lib etc, it is NOT the actual Python, which is in a Mac OS "Framework". Do this:

PYTHONHOME=/usr/local/Cellar/python3/3.x.y/Frameworks/Python.framework/Versions/3.x
PYTHONPATH=$PYTHONHOME/bin

(substituting version numbers as appropriate) and it will work fine.

Apparently some POST requests looks like a "GET" to the server (like Heroku...)

So I use this strategy and it works for me:

@RequestMapping(value = "/salvar", method = { RequestMethod.GET, RequestMethod.POST })

i found another solution:

1. start session in TEAM
2. go to SOURCE CONTROL and select WORKSPACE (mark in red)
3. then Add new Workspace... why?
4. because you dont work in the same workspace whey you change your account in TFS (i dont know why)
5. and ready to MAP your project again.

Its 100% guaranteed to work.

From any Context use:

getApplicationInfo().loadLabel(getPackageManager()).toString();

Given: [x1,x2] [y1,y2] then x1 <= y2 || x2 >= y1 would work always. as

      x1 ... x2
y1 .... y2

if x1 > y2 then they do not overlap or

x1 ... x2
    y1 ... y2

if x2 < y1 they do not overlap.

If it contains less than 3 slashes thus you've it got and if not then we can find the occurrence between it:

import re

link = http://forum.unisoftdev.com/something

slash_count = len(re.findall("/", link))
print slash_count # output: 3

if slash_count > 2:
   regex = r'\:\/\/(.*?)\/'
   pattern  = re.compile(regex)
   path = re.findall(pattern, url)

   print path

Here is best solution for this issue: In View add all the ID (Keys). Consider having multiple tables named (First, Second and Third)

@Html.HiddenFor(model=>model.FirstID)
@Html.HiddenFor(model=>model.SecondID)
@Html.HiddenFor(model=>model.Second.SecondID)
@Html.HiddenFor(model=>model.Second.ThirdID)
@Html.HiddenFor(model=>model.Second.Third.ThirdID)

In C# code,

[HttpPost]
public ActionResult Edit(First first)
{
  if (ModelState.Isvalid)
  {
    if (first.FirstID > 0)
    {
      datacontext.Entry(first).State = EntityState.Modified;
      datacontext.Entry(first.Second).State = EntityState.Modified;
      datacontext.Entry(first.Second.Third).State = EntityState.Modified;
    }
    else
    {
      datacontext.First.Add(first);
    }
    datacontext.SaveChanges();
    Return RedirectToAction("Index");
  }

 return View(first);
}

You can either directly pass line terminator e.g. \n, if you know the line terminator in Windows, Mac or UNIX. Alternatively you can use following code to replace line breaks in either of three major operating system.

str = str.replaceAll("\\r\\n|\\r|\\n", " ");

Above code line will replace line breaks with space in Mac, Windows and Linux. Also you can use line-separator. It will work for all OS. Below is the code snippet for line-separator.

String lineSeparator=System.lineSeparator();
String newString=yourString.replace(lineSeparator, "");

I found that I had to place a special z-index designation on div in a ie7 specific styelsheet:

div { z-index:10; }

For the z-index of unrelated divs, such as a nav, to show above the slider. I could not simply add a z-index to the slider div itself.

I know its been a while since the original post but I like using CTE's and this worked for me:

WITH cte_table_a
AS
(
    SELECT [id] [id]
    , MAX([value]) [value]
    FROM table_a
    GROUP BY [id]
)
UPDATE table_b
SET table_b.code = CASE WHEN cte_table_a.[value] IS NOT NULL THEN cte_table_a.[value] ELSE 124 END
FROM table_b
LEFT OUTER JOIN  cte_table_a
ON table_b.id = cte_table_a.id

As others have mentioned, the load data local infile works just fine. I tried the php script that Hawkee posted, but didnt work for me. Rather than debug it, here's what i did:

1) copy/paste the header row of the CSV file into a txt file and edit with emacs. add a comma and CR between each field to get each on on it's own line.
2) Save that file as FieldList.txt
3) edit the file to include defns for each field (most were varchar, but quite a few were int(x). Add create table tablename ( to the beginning of the file and ) to the end of the file. Save it as CreateTable.sql
4) start mysql client with input from the Createtable.sql file to create the table
5) start mysql client, copy/paste in most of the 'LOAD DATA INFILE' command subsituting my table name and csv file name. Paste in the FieldList.txt file. Be sure to include the 'IGNORE 1 LINES' before pasting in the field list

Sounds like a lot of work, but easy with emacs.....

I had a "Install build tools and sync" link in the lower right hand corner of my screen. I clicked on that and it fixed the issue.

empty is an operator:

The empty operator is a prefix operation that can be used to determine whether a value is null or empty.

<c:if test="${empty myObject.featuresList}">

Here's a variation that ignores and preserves case:

jQuery.fn.highlight = function (str, className) {
    var regex = new RegExp("\\b"+str+"\\b", "gi");

    return this.each(function () {
        this.innerHTML = this.innerHTML.replace(regex, function(matched) {return "<span class=\"" + className + "\">" + matched + "</span>";});
    });
};

You should use the TryParse method for the int

string text1 = "x";
    int num1;
    bool res = int.TryParse(text1, out num1);
    if (res == false)
    {
        // String is not a number.
    }
