Here's my current solution to run any code remotely on a given machine or list of machines asynchronously with logging, too!

@echo off
:: by Ralph Buchfelder, thanks to Mark Russinovich and Rob van der Woude for their work!
:: requires PsExec.exe to be in the same directory (download from http://technet.microsoft.com/de-de/sysinternals/bb897553.aspx)
:: troubleshoot remote commands with PsExec arguments -i or -s if neccessary (see http://forum.sysinternals.com/pstools_forum8.html)
:: will run *in parallel* on a list of remote pcs (if given); to run serially please remove 'START "" CMD.EXE /C' from the psexec call

Accepted answer doesn't work for me, but this does. Ensure script in the location (c:\temp_ below on each remote server. servers.txt contains a list of IP addresses (one per line).

psexec @servers.txt -u <username> cmd /c "powershell -noninteractive -file C:\temp\script.ps1"

Under Java 8 use the predefined DateTimeFormatter.ISO_DATE_TIME

 DateTimeFormatter formatter = DateTimeFormatter.ISO_DATE_TIME;
 ZonedDateTime result = ZonedDateTime.parse("2010-04-05T17:16:00Z", formatter);

I guess its the easiest way

Actually, it's quite easy: instead of the number of bins you can give a list with the bin boundaries. They can be unequally distributed, too:

plt.hist(data, bins=[0, 10, 20, 30, 40, 50, 100])

If you just want them equally distributed, you can simply use range:

plt.hist(data, bins=range(min(data), max(data) + binwidth, binwidth))

Added to original answer

The above line works for data filled with integers only. As macrocosme points out, for floats you can use:

import numpy as np
plt.hist(data, bins=np.arange(min(data), max(data) + binwidth, binwidth))

You can pass multiple parameters as "?param1=value1&param2=value2"

But it's not secure. It's vulnerable to Cross Site Scripting (XSS) Attack.

Your parameter can be simply replaced with a script.

Have a look at this article and article

You can make it secure by using API of StringEscapeUtils

static String   escapeHtml(String str) 
          Escapes the characters in a String using HTML entities.

Even using https url for security without above precautions is not a good practice.

Have a look at related SE question:

Is URLEncoder.encode(string, "UTF-8") a poor validation?

2020 solution:

I wrote a PHP function which uses the Vimeo Oembed API.

/**
 * Get Vimeo.com video thumbnail URL
 *
 * Set the referer parameter if your video is domain restricted.
 * 
 * @param  int    $videoid   Video id
 * @param  URL    $referer   Your website domain
 * @return bool/string       Thumbnail URL or false if can't access the video
 */
function get_vimeo_thumbnail_url( $videoid, $referer=null ){

    // if referer set, create context
    $ctx = null;
    if( isset($referer) ){
        $ctxa = array(
            'http' => array(
                'header' => array("Referer: $referer\r\n"),
                'request_fulluri' => true,
            ),
        );
        $ctx = stream_context_create($ctxa);
    }

    $resp = @file_get_contents("https://vimeo.com/api/oembed.json?url=https://vimeo.com/$videoid", False, $ctx);
    $resp = json_decode($resp, true);

return $resp["thumbnail_url"]??false;
}

Usage:

echo get_vimeo_thumbnail_url("1084537");

$( ".datepicker_recurring_start" ).each(function(){
    $(this).datepicker({
        dateFormat:"dd/mm/yy",
        yearRange: '2000:2012',
        changeYear: true,
        changeMonth: true
    });
});

I created a Bash script that basically automates the manual installation described in the linked similar question. It requires the tar.gz file as well as its SHA256 sum value. You can find out more info and download the script from my GitHub project page. It is provided under MIT license.

Update : STYLE GUIDE is now on Angular docs.

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

If you are looking for an opinionated style guide for syntax, conventions, and structuring AngularJS applications, then step right in. The styles contained here are based on my experience with AngularJS, presentations, training courses and working in teams.

The purpose of this style guide is to provide guidance on building AngularJS applications by showing the conventions I use and, more importantly, why I choose them.

- John Papa

Here is the Awesome Link (Latest and Up-to-date) : AngularJS Style Guide

I believe the point here is that even if a collection is Unmodifiable, that does not ensure that it cannot change. Take for example a collection that evicts elements if they are too old. Unmodifiable just means that the object holding the reference cannot change it, not that it cannot change. A true example of this is Collections.unmodifiableList method. It returns an unmodifiable view of a List. The the List reference that was passed into this method is still modifiable and so the list can be modified by any holder of the reference that was passed. This can result in ConcurrentModificationExceptions and other bad things.

Immutable, mean that in no way can the collection be changed.

Second question: An Immutable collection does not mean that the objects contained in the collection will not change, just that collection will not change in the number and composition of objects that it holds. In other words, the collection's list of references will not change. That does not mean that the internals of the object being referenced cannot change.

null is not zero. It is not a value, per se: it is a value outside the domain of the variable indicating missing or unknown data.

There is only one way to represent null in JSON. Per the specs (RFC 4627 and json.org):

2.1.  Values

A JSON value MUST be an object, array, number, or string, or one of
the following three literal names:

  false null true

I strongly suspect the problem is to do with namespaces. Try getting rid of the namespace and you'll be fine - but obviously that won't help in your real case, where I'd assume the document is fixed.

I can't remember offhand how to specify a namespace in an XPath expression, but I'm sure that's the problem.

EDIT: Okay, I've remembered how to do it now. It's not terribly pleasant though - you need to create an XmlNamespaceManager for it. Here's some sample code that works with your sample document:

using System;
using System.Xml;

public class Test
{
    static void Main()
    {
        XmlDocument doc = new XmlDocument();
        XmlNamespaceManager namespaces = new XmlNamespaceManager(doc.NameTable);
        namespaces.AddNamespace("ns", "urn:hl7-org:v3");
        doc.Load("test.xml");
        XmlNode idNode = doc.SelectSingleNode("/My_RootNode/ns:id", namespaces);
        string msgID = idNode.Attributes["extension"].Value;
        Console.WriteLine(msgID);
    }
}

I've been searching high and low for an end-to-end example of a complete maven-based ear-packaged application and finally stumbled upon this. The instructions say to select option 2 when running through the CLI but for your purposes, use option 1.

Simply add the eventhandler to the button when creating it.

 button.Click += new EventHandler(this.button_Click);

void button_Click(object sender, System.EventArgs e)
{
//your stuff...
}

Use the System.Runtime.InteropServices.Marshal class:

String SecureStringToString(SecureString value) {
  IntPtr valuePtr = IntPtr.Zero;
  try {
    valuePtr = Marshal.SecureStringToGlobalAllocUnicode(value);
    return Marshal.PtrToStringUni(valuePtr);
  } finally {
    Marshal.ZeroFreeGlobalAllocUnicode(valuePtr);
  }
}

If you want to avoid creating a managed string object, you can access the raw data using Marshal.ReadInt16(IntPtr, Int32):

void HandleSecureString(SecureString value) {
  IntPtr valuePtr = IntPtr.Zero;
  try {
    valuePtr = Marshal.SecureStringToGlobalAllocUnicode(value);
    for (int i=0; i < value.Length; i++) {
      short unicodeChar = Marshal.ReadInt16(valuePtr, i*2);
      // handle unicodeChar
    }
  } finally {
    Marshal.ZeroFreeGlobalAllocUnicode(valuePtr);
  }
}

In my case, I had to initiate a clean project from SVN

$ Project> git svn init protocol://path/to/repo -s
$ Project> git svn fetch

add all your project sources...

$ Project> git add .
$ Project> git commit -m "Importing project sources"
$ Project> git svn dcommit

Run the cmd as run as administrator this worked for me

This code reads the file line by line.

public static void readFileByLine(String fileName) {
  try {
   File file = new File(fileName);
   Scanner scanner = new Scanner(file);
   while (scanner.hasNext()) {
    System.out.println(scanner.next());
   }
   scanner.close();
  } catch (FileNotFoundException e) {
   e.printStackTrace();
  } 
 }

You can also set a delimiter as a line separator and then perform the same.

 scanner.useDelimiter(System.getProperty("line.separator"));

You have to check whether there is a next token available and then read the next token. You will also need to doublecheck the input given to the Scanner. i.e. dico.txt. By default, Scanner breaks its input based on whitespace. Please ensure that the input has the delimiters in right place

UPDATED ANSWER for your comment:

I just tried to create an input file with the content as below

a
à
abaissa
abaissable
abaissables
abaissai
abaissaient
abaissais
abaissait

tried to read it with the below code.it just worked fine.

 File file = new File("/home/keerthivasan/Desktop/input.txt");
     Scanner scr = null;
         try {
            scr = new Scanner(file);
            while(scr.hasNext()){
                System.out.println("line : "+scr.next());
            }
        } catch (FileNotFoundException ex) {
            Logger.getLogger(ScannerTest.class.getName()).log(Level.SEVERE, null, ex);
        }

Output:

line : a
line : à
line : abaissa
line : abaissable
line : abaissables
line : abaissai
line : abaissaient
line : abaissais
line : abaissait

so, I am sure that this should work. Since you work in Windows ennvironment, The End of Line (EOL) sequence (0x0D 0x0A, \r\n) is actually two ASCII characters, a combination of the CR and LF characters. if you set your Scanner instance to use delimiter as follows, it will pick up probably

 scr = new Scanner(file);
 scr.useDelimiter("\r\n");

and then do your looping to read lines. Hope this helps!

This simple example works for me...

HTML

<input type="text" id="datepicker">

JavaScript

var $datepicker = $('#datepicker');
$datepicker.datepicker();
$datepicker.datepicker('setDate', new Date());

I was able to create this by simply looking @ the manual and reading the explanation of setDate:

.datepicker( "setDate" , date )
Sets the current date for the datepicker. The new date may be a Date object or a string in the current date format (e.g. '01/26/2009'), a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null to clear the selected date.

Excellent answer from Chepner. It is working for me in bash Shell.

 # To update/replace the new line string value with the exiting line of the file
 MyFile=/tmp/ps_checkdb.flag

 `sed -i "${index}s/.*/${newLine}/" $MyFile`

here
index - Line no
newLine - new line string which we want to replace.


Similarly below code is used to read a particular line in the file. This won't affect the actual file.

LineString=`sed "$index!d" $MyFile` 

here
!d - will delete the lines other than line no $index So we will get the output as line string of no $index in the file.

Translated from here:

Dimension getScaledDimension(Dimension imageSize, Dimension boundary) {

    double widthRatio = boundary.getWidth() / imageSize.getWidth();
    double heightRatio = boundary.getHeight() / imageSize.getHeight();
    double ratio = Math.min(widthRatio, heightRatio);

    return new Dimension((int) (imageSize.width  * ratio),
                         (int) (imageSize.height * ratio));
}

You can also use imgscalr to resize images while maintaining aspect ratio:

BufferedImage resizeMe = ImageIO.read(new File("orig.jpg"));
Dimension newMaxSize = new Dimension(255, 255);
BufferedImage resizedImg = Scalr.resize(resizeMe, Method.QUALITY,
                                        newMaxSize.width, newMaxSize.height);

There are several ways to convert SVG to PNG using the Canvg library.

In my case, I needed to get the PNG blob from inline SVG.

The library documentation provides an example (see OffscreenCanvas example).

But this method does not work at the moment in Firefox. Yes, you can enable the gfx.offscreencanvas.enabled option in the settings. But will every user on the site do this? :)

However, there is another way that will work in Firefox too.

const el = document.getElementById("some-svg"); //this is our inline SVG

var canvas = document.createElement('canvas'); //create a canvas for the SVG render
canvas.width = el.clientWidth; //set canvas sizes
canvas.height = el.clientHeight;

const svg = new XMLSerializer().serializeToString(el); //convert SVG to string

//render SVG inside canvas
const ctx = canvas.getContext('2d');
const v = await Canvg.fromString(ctx, svg);
await v.render();

let canvasBlob = await new Promise(resolve => canvas.toBlob(resolve));

For the last line thanks to this answer

You need to remove the / before the [. Predicates (the parts in [ ]) shouldn't have slashes immediately before them. Also, to select the Employee element itself, you should leave off the /text() at the end or otherwise you'd just be selecting the whitespace text values immediately under the Employee element.

//Employee[@id='4']

Edit: As Jens points out in the comments, // can be very slow because it searches the entire document for matching nodes. If the structure of the documents you're working with is going to be consistent, you are probably best off using a full path, for example:

/Employees/Employee[@id='4']

you have to move the adb command to /bin/ folder

in my case:

sudo su
mv /root/Android/Sdk/platform-tools/adb /bin/

JSFiddle Demonstration

This is what I use with JQuery:

$('.button').on('click', function () { 
    var obj = document.createElement("audio");
        obj.src = "linktoyourfile.wav"; 
        obj.play(); 
});

Assuming you have a "sampleDS" datasource definition inside your tomcat configuration, you can add following lines to your applicationContext.xml to access the datasource using JNDI.

<jee:jndi-lookup expected-type="javax.sql.DataSource" id="springBeanIdForSampleDS" jndi-name="sampleDS"/>

You have to define the namespace and schema location for jee prefix using:

xmlns:jee="http://www.springframework.org/schema/jee"
xsi:schemaLocation="http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd"

Recognizing only numbers is actually answered on the tesseract FAQ page. See that page for more info, but if you have the version 3 package, the config files are already set up. You just specify on the commandline:

tesseract image.tif outputbase nobatch digits

As for the threshold value, I'm not sure which you mean. If your input is an unusual font, perhaps you might retrain with a sample of your input. An alternative is to change tesseract's pruning threshold. Both options are also mentioned in the FAQ.

For those want to use pragma table_info()'s result as part of a larger SQL.

select count(*) from
pragma_table_info('<table_name>')
where name='<column_name>';

The key part is to use pragma_table_info('<table_name>') instead of pragma table_info('<table_name>').

This answer is inspired by @Robert Hawkey 's reply. The reason I post it as a new answer is I don't have enough reputation to post it as comment.

DEFAULT is the value that will be inserted in the absence of an explicit value in an insert / update statement. Lets assume, your DDL did not have the NOT NULL constraint:

ALTER TABLE tbl ADD COLUMN col VARCHAR(20) DEFAULT 'MyDefault'

Then you could issue these statements

-- 1. This will insert 'MyDefault' into tbl.col
INSERT INTO tbl (A, B) VALUES (NULL, NULL);

-- 2. This will insert 'MyDefault' into tbl.col
INSERT INTO tbl (A, B, col) VALUES (NULL, NULL, DEFAULT);

-- 3. This will insert 'MyDefault' into tbl.col
INSERT INTO tbl (A, B, col) DEFAULT VALUES;

-- 4. This will insert NULL into tbl.col
INSERT INTO tbl (A, B, col) VALUES (NULL, NULL, NULL);

Alternatively, you can also use DEFAULT in UPDATE statements, according to the SQL-1992 standard:

-- 5. This will update 'MyDefault' into tbl.col
UPDATE tbl SET col = DEFAULT;

-- 6. This will update NULL into tbl.col
UPDATE tbl SET col = NULL;

Note, not all databases support all of these SQL standard syntaxes. Adding the NOT NULL constraint will cause an error with statements 4, 6, while 1-3, 5 are still valid statements. So to answer your question: No, they're not redundant.

First of all you have to fetch the remote repository:

git fetch remoteName

Than you can create the new branch and set it up to track the remote branch you want:

git checkout -b newLocalBranch remoteName/remoteBranch

You can also use "git branch --track" instead of "git checkout -b" as max specified.

git branch --track newLocalBranch remoteName/remoteBranch

You've forgot to define an onclick attribute to do something when the button is clicked, so nothing happening is the correct execution, see below;

<input type="button" id="moreFields" onclick="moreFields()" value="Give me more fields!"  />
                                     ----------------------

You can use Regular Expressions

if(System.Text.RegularExpressions.IsMatch("a|b|c"))

Here are some high level thoughts and info that might help, aside from the other answers.

Pollyfills are like a compatability patch for specific browsers. Shims are changes to specific arguments. Fallbacks can be used if say a @mediaquery is not compatible with a browser.

It kind of depends on the requirements of what your app/website needs to be compatible with.

You cna check this site out for compatability of specific libraries with specific browsers. https://caniuse.com/

You can use a different overload of Replace() that takes string.

val = val.Replace("-", string.Empty)

1st way is to use props

<Row id = "someRandomID">

Wherein, in the Definition, you may just go

const Row = props  => {
 div id = {props.id}
}

The same could be done with class, replacing id with className in the above example.

You might as well use react-html-id, that is an npm package. This is an npm package that allows you to use unique html IDs for components without any dependencies on other libraries.

Ref: react-html-id

Peace.

This is another method . Passing array as a pointer to the function
void generateArray(int *array,  int size) {
    srand(time(0));
    for (int j=0;j<size;j++)
        array[j]=(0+rand()%9);
}

int main(){
    const int size=5;
    int a[size];
    generateArray(a, size);
    return 0;
}

Just for the record solution that works across most database engines though might not be the most efficient:

Select Top (ReturnCount) *
From (
    Select Top (SkipCount + ReturnCount) *
    From SourceTable
    Order By ReverseSortCondition
) ReverseSorted
Order By SortCondition

Pelase note: the last page would still contain ReturnCount rows no matter what SkipCount is. But that might be a good thing in many cases.

$id = mysql_result(mysql_query("SELECT id FROM games LIMIT 1"),0);

just combine the value and the stud_name e.g. 1_sre and split the value when get it into php. Javascript seems like hammer to crack a nut. N.B. this method assumes you can edit the the html. Here is what the html might look like:

<form name='add'>
Age: <select name='age'>
     <option value='1_sre'>23</option>
     <option value='2_sam>24</option>
     <option value='5_john>25</option>
     </select>
<input type='submit' name='submit'/>
</form>

When one uses flow_from_directory the problem is how to interpret the probability outputs. As in, how to map the probability outputs and the class labels as how flow_from_directory creates one-hot vectors is not known in prior.

We can get a dictionary that maps the class labels to the index of the prediction vector that we get as the output when we use

generator= train_datagen.flow_from_directory("train", batch_size=batch_size)
label_map = (generator.class_indices)

The label_map variable is a dictionary like this

{'class_14': 5, 'class_10': 1, 'class_11': 2, 'class_12': 3, 'class_13': 4, 'class_2': 6, 'class_3': 7, 'class_1': 0, 'class_6': 10, 'class_7': 11, 'class_4': 8, 'class_5': 9, 'class_8': 12, 'class_9': 13}

Then from this the relation can be derived between the probability scores and class names.

Basically, you can create this dictionary by this code.

from glob import glob
class_names = glob("*") # Reads all the folders in which images are present
class_names = sorted(class_names) # Sorting them
name_id_map = dict(zip(class_names, range(len(class_names))))

The variable name_id_map in the above code also contains the same dictionary as the one obtained from class_indices function of flow_from_directory.

Hope this helps!

By Default angular return responseType as Json, but we can configure below types according to your requirement.

responseType: 'arraybuffer'|'blob'|'json'|'text'

Ex:

this.http.post(
    'http://localhost:8080/order/addtocart', 
    { dealerId: 13, createdBy: "-1", productId, quantity }, 
    { headers, responseType: 'text'});

I don't think var per say is a terrible language feature, as I use it daily with code like what Jeff Yates described. Actually, almost everytime I use var is because generics can make for some extremely wordy code. I live verbose code but generics take it a step too far.

That said, I (obviously... ) think var is ripe for abuse. If code gets to 20+ lines in a method with vars littered through out, you will quickly make maintenance a nightmare. Additionally, var in a tutorial is incredibly counter intuitive and generally is a giant no-no in my books.

On the flipside, var is an "easy" feature that new programmers are going to latch onto and love. Then, within a few minutes/hours/days hit a massive roadblock when they start hitting the limits. "Why can't I return var from functions?" That kind of question. Also, adding a pseudo dynamic type to a strongly typed language is something that can easily trip up a new developer. In the long run, I think the var keyword will actually make c# harder to learn for new programmers.

That said, as an experienced programmer I do use var, mostly when dealing with generics ( and obviously anonymous types ). I do hold by my quote, I do believe var will be one of the worst abused c# features.

Recommended: don't translate in the controller, translate in your view

I'd recommend to keep your controller free from translation logic and translate your strings directly inside your view like this:

<h1>{{ 'TITLE.HELLO_WORLD' | translate }}</h1>

Using the provided service

Angular Translate provides the $translate service which you can use in your Controllers.

An example usage of the $translate service can be:

.controller('TranslateMe', ['$scope', '$translate', function ($scope, $translate) {
    $translate('PAGE.TITLE')
        .then(function (translatedValue) {
            $scope.pageTitle = translatedValue;
        });
});

The translate service also has a method for directly translating strings without the need to handle a promise, using $translate.instant():

.controller('TranslateMe', ['$scope', '$translate', function ($scope, $translate) {
    $scope.pageTitle = $translate.instant('TITLE.DASHBOARD'); // Assuming TITLE.DASHBOARD is defined
});

The downside with using $translate.instant() could be that the language file isn't loaded yet if you are loading it async.

Using the provided filter

This is my preferred way since I don't have to handle promises this way. The output of the filter can be directly set to a scope variable.

.controller('TranslateMe', ['$scope', '$filter', function ($scope, $filter) {
    var $translate = $filter('translate');

    $scope.pageTitle = $translate('TITLE.DASHBOARD'); // Assuming TITLE.DASHBOARD is defined
});

Using the provided directive

Since @PascalPrecht is the creator of this awesome library, I'd recommend going with his advise (see his answer below) and use the provided directive which seems to handle translations very intelligent.

The directive takes care of asynchronous execution and is also clever enough to unwatch translation ids on the scope if the translation has no dynamic values.

Yes, in order for the z-index to work, you'll need to give the element a position: absolute or a position: relative property.

But... pay attention to parents!

You have to go up the nodes of the elements to check if at the level of the common parent the first descendants have a defined z-index.

All other descendants can never be in the foreground if at the base there is a lower definite z-index.

In this snippet example, div1-2-1 has a z-index of 1000 but is nevertheless under the div1-1-1 which has a z-index of 3.

This is because div1-1 has a z-index greater than div1-2.

.div {
  
}

#div1 {
  z-index: 1;
  position: absolute;
  width: 500px;
  height: 300px;
  border: 1px solid black;
}

#div1-1 {
  z-index: 2;
  position: absolute;
  left: 230px;
  width: 200px;
  height: 200px;
  top: 31px;
  background-color: indianred;
}

#div1-1-1 {
  z-index: 3;
  position: absolute;
  top: 50px;
  width: 100px;
  height: 100px;
  background-color: burlywood;
}

#div1-2 {
  z-index: 1;
  position: absolute;
  width: 200px;
  height: 200px;
  left: 80px;
  top: 5px;
  background-color: red;
}

#div1-2-1 {
  z-index: 1000;
  position: absolute;
  left: 70px;
  width: 120px;
  height: 100px;
  top: 10px;
  color: red;
  background-color: lightyellow;
}

.blink {
  animation: blinker 1s linear infinite;
}

@keyframes blinker {
  50% {
    opacity: 0;
  }
}

.rotate {
  writing-mode: vertical-rl;
  padding-left: 50px;
  font-weight: bold;
  font-size: 20px;
}

<div class="div" id="div1">div1</br>z-index: 1
  <div class="div" id="div1-1">div1-1</br>z-index: 2
    <div class="div" id="div1-1-1">div1-1-1</br>z-index: 3</div>
  </div>
  
  <div class="div" id="div1-2">div1-2</br>z-index: 1</br><span class='rotate blink'><=</span>
    <div class="div" id="div1-2-1"><span class='blink'>z-index: 1000!!</span></br>div1-2-1</br><span class='blink'> because =></br>(same</br>   parent)</span></div>
  </div>

You might like the function GetInfoFromClosedFile()

Edit: Since the above link does not seem to work anymore, I am adding alternate link 1 and alternate link 2 + code:

Private Function GetInfoFromClosedFile(ByVal wbPath As String, _
    wbName As String, wsName As String, cellRef As String) As Variant
Dim arg As String
    GetInfoFromClosedFile = ""
    If Right(wbPath, 1) <> "" Then wbPath = wbPath & ""
    If Dir(wbPath & "" & wbName) = "" Then Exit Function
    arg = "'" & wbPath & "[" & wbName & "]" & _
        wsName & "'!" & Range(cellRef).Address(True, True, xlR1C1)
    On Error Resume Next
    GetInfoFromClosedFile = ExecuteExcel4Macro(arg)
End Function

ActionLink will never fire post. It always trigger GET request.

The only thing that worked for me is this:

In project.properties, I changed:

cordova.system.library.1=com.android.support:support-v4:+ to cordova.system.library.1=com.android.support:support-v4:20.+

Somewhere around r59 this gets easier (rotate around x):

bb.GraphicsEngine.prototype.calcRotation = function ( obj, rotationX)
{
    var euler = new THREE.Euler( rotationX, 0, 0, 'XYZ' );
    obj.position.applyEuler(euler);
}

The problem I was having is that drop box was putting its overlays in at a higher priority than SVN

They both put spaces on the beginning of the entries to push them to the top of the list in

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ Explorer\ShellIconOverlayIdentifiers\

The following article explains this more fully and shows how to fix it.

https://www.garethjmsaunders.co.uk/2015/03/22/managing-overlay-icons-for-dropbox-and-tortoisesvn-and-tortoisegit/

However as dropbox gets updated relativity frequently on my machine, and I rarely update Tortoise SVN I would suggest just appending spaces to the tortoise entries to push them up the list, otherwise you'll have to do all this again when a dropbox software update is installed.

I don't think you can at present: see this article on the Postgresql wiki.

The three workarounds from this article are:

1. Recreate the table
2. Add columns and move data
3. Hide the differences with a view.

CSS transformations create a new stacking context and containing block, as described in the spec. In plain English, this means that fixed position elements with a transformation applied to them will act more like absolutely positioned elements, and z-index values are likely to get screwed with.

If you take a look at this demo, you'll see what I mean. The second div has a transformation applied to it, meaning that it creates a new stacking context, and the pseudo elements are stacked on top rather than below.

So basically, don't do that. Apply a 3D transformation only when you need the optimization. -webkit-font-smoothing: antialiased; is another way to tap into 3D acceleration without creating these problems, but it only works in Safari.

The question is about matplotlib, but for the sake of any R users that end up here given the language-agnostic title:

If you're using an R kernel, just use:

options(repr.plot.width=4, repr.plot.height=3)

String ss = "Pawan kavita kiyansh Patidar Patidar";
    StringBuilder ress = new StringBuilder();
    
    Map<Character, Integer> fre = ss.chars().boxed()
            .collect(Collectors.toMap(k->Character.valueOf((char) k.intValue()),k->1,Integer::sum));
    
      //fre.forEach((k, v) -> System.out.println((k + ":" + v)));
    
    fre.entrySet().forEach(e ->{
            //System.out.println(e.getKey() + ":" + e.getValue());
            //ress.append(String.valueOf(e.getKey())+e.getValue());
        }); 

    fre.forEach((k,v)->{
        //System.out.println("Item : " + k + " Count : " + v);
        ress.append(String.valueOf(k)+String.valueOf(v));
    });
    
    System.out.println(ress.toString());

The most efficient and safest way to determine if a row exists is by using a FOR-LOOP... You won't even have a difficult time if you are looking to insert a row or do something based on the row NOT being there but, this will certainly help you if you need to determine if a row exists. See example code below for the ins and outs...

If you are only interested in knowing that 1 record exists in your potential multiple return set, than you can exit your loop after it hits it for the first time.

The loop will not be entered into at all if no record exists. You will not get any complaints from Oracle or such if the row does not exist but you are bound to find out if it does regardless. Its what I use 90% of the time (of course dependent on my needs)...

EXAMPLE:

DECLARE

v_exist varchar2(20);

BEGIN
   FOR rec IN
   (SELECT LOT, COMPONENT 
   FROM TABLE
   WHERE REF_DES = (SELECT REF_DES FROM TABLE2 WHERE ORDER = '1234') 
   AND ORDER = '1234')
  LOOP

      v_exist := "IT_EXISTS"

   INSERT INTO EAT_SOME_SOUP_TABLE (LOT, COMPONENT) 
   VALUES (rec.LOT, rec.COMPONENT);**

   --Since I don't want to do this for more than one iteration (just in case there may have been more than one record returned, I will EXIT;

   EXIT;
   END LOOP;



IF v_exist  IS NULL

    THEN

            --do this

END IF;

END;

--This is outside the loop right here The IF-CHECK just above will run regardless, but then you will know if your variable is null or not right!?. If there was NO records returned, it will skip the loop and just go here to the code you would have next... If (in our case above), 4 records were returned, I would exit after the first iteration due to my EXIT;... If that wasn't there, the 4 records would iterate through and do an insert on all of them. Or at least try too.

By the way, I'm not saying this is the only way you should consider doing this... You can

SELECT COUNT(*) INTO v_counter WHERE ******* etc...

Then check it like

if v_counter > 0
      THEN
         --code goes here
   END IF;

There are more ways... Just determine it when your need arises. Keep performance in mind, and safety.

Resetting Staged Changes and Commits

The git reset command lets you change the HEAD- the latest commit your working tree points to - of your repository. It modifies either the staging area or the staging area and working tree.

Git's ability to craft commits exactly like you want means that you sometimes need to undo changes to the changes you staged with git add. You can do that by calling git reset HEAD <file to change>.

You have two options to get rid of changes completely. git checkout HEAD <file(s) or path(s)> is a quick way to undo changes to your staging area and working tree. Be careful with this command, however, because it removes all changes to your working tree.

Git doesn't know about those changes since they've never been committed. There's no way to get those changes back once you run this command.

Another command at your disposal is git reset --hard. It is equally destructive to your working tree - any uncommitted changes or staged changes are lost after running it. Running git reset -hard HEAD does the same thing as git checkout HEAD. It just doesn't require a file or path to work.

You can use --soft with git reset. It resets the repository to the commit you specify and stages all of those changes. Any changes you have already staged are not affected, nor are the changes in your working tree.

Finally, you can use --mixed to reset the working tree without staging any changes. This also unstages any changes that are staged.

Reverting Commits

Sometimes we make mistakes. A commit that wasn't supposed to be shared gets pushed to a public repository, a commit has a bug that can't be fixed and needs to be undone, or maybe you just don't need that code any longer.

These cases all call for git revert. The git revert command does just what you might expect. It reverts a single commit by applying a reverse commit to the history.

Sometimes you need to revert several commits to completely undo a change. You can use -no-commit, or you can use -n to tell Git to perform the revert, but stop short of committing the change.

This lets you combine all the revert commits into one commit, which is useful if you need to revert a feature that spans several commits. Make sure that you revert commits in reverse order-the newest commit first.

Otherwise, you might confuse Git by trying to revert code that doesn't exist yet.

A handle is a unique identifier for an object managed by Windows. It's like a pointer, but not a pointer in the sence that it's not an address that could be dereferenced by user code to gain access to some data. Instead a handle is to be passed to a set of functions that can perform actions on the object the handle identifies.

Even though this an older question I stumbled here looking for a solution to a similar issue. After trying some of the solutions here I ended up going a different direction and thought I would add my solution for anyone else who ends up here.

In express 4.x you can get an instance of the router object and import another file that contains more routes. You can even do this recursively so your routes import other routes allowing you to create easy to maintain url paths. For example if I have a separate route file for my '/tests' endpoint already and want to add a new set of routes for '/tests/automated' I may want to break these '/automated' routes out into a another file to keep my '/test' file small and easy to manage. It also lets you logically group routes together by URL path which can be really convenient.

Contents of ./app.js:

var express = require('express'),
    app = express();

var testRoutes = require('./routes/tests');

// Import my test routes into the path '/test'
app.use('/tests', testRoutes);

Contents of ./routes/tests.js

var express = require('express'),
    router = express.Router();

var automatedRoutes = require('./testRoutes/automated');

router
  // Add a binding to handle '/tests'
  .get('/', function(){
    // render the /tests view
  })

  // Import my automated routes into the path '/tests/automated'
  // This works because we're already within the '/tests' route so we're simply appending more routes to the '/tests' endpoint
  .use('/automated', automatedRoutes);
 
module.exports = router;

Contents of ./routes/testRoutes/automated.js:

var express = require('express'),
    router = express.Router();

router
   // Add a binding for '/tests/automated/'
  .get('/', function(){
    // render the /tests/automated view
  })

module.exports = router;

Try this

div:nth-child(4n+4)

Did you change any thing on the virtual-host before it stop working ?

Add this line to xampp/apache/conf/extra/httpd-vhosts.conf

<VirtualHost localhost:80>
    DocumentRoot "C:/xampp/htdocs"
    ServerAdmin localhost
    <Directory "C:/xampp/htdocs">
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

Opaque responses can't be accessed by JavaScript, but you can still cache them with the Cache API and respond with them in the fetch event handler in a service worker. So they're useful for making your app offline, also for resources that you can't control (e.g. resources on a CDN that doesn't set the CORS headers).

Declare where display: flex; was given Element.
align-items: center;

@Tim's answer only does half the work -- that gets it into a datetime.datetime object.

To get it into the string format you require, you use datetime.strftime:

print(datetime.strftime('%b %d,%Y'))

Try casting to List in the extension method before running the loop. That way you can take advantage of the performance of List.AddRange.

public static void AddRange<T>(this ICollection<T> destination,
                               IEnumerable<T> source)
{
    List<T> list = destination as List<T>;

    if (list != null)
    {
        list.AddRange(source);
    }
    else
    {
        foreach (T item in source)
        {
            destination.Add(item);
        }
    }
}

This is the cleanest and most elegant/simple way to get a solution here.

Brilliant blog post and no messy overkill in writing custom extension/helper methods like a mad professor.

Sth, i sink that's pretty ;)

def pretty(d, indent=0):
    for key, value in d.iteritems():
        if isinstance(value, dict):
            print '\t' * indent + (("%30s: {\n") % str(key).upper())
            pretty(value, indent+1)
            print '\t' * indent + ' ' * 32 + ('} # end of %s #\n' % str(key).upper())
        elif isinstance(value, list):
            for val in value:
                print '\t' * indent + (("%30s: [\n") % str(key).upper())
                pretty(val, indent+1)
                print '\t' * indent + ' ' * 32 + ('] # end of %s #\n' % str(key).upper())
        else:
            print '\t' * indent + (("%30s: %s") % (str(key).upper(),str(value)))

I was playing with this and came up with an alternative.

$ VAR=/home/me/mydir/file.c

$ DIR=`echo $VAR |xargs dirname`

$ echo $DIR
/home/me/mydir

The part I liked is it was easy to extend backup the tree:

$ DIR=`echo $VAR |xargs dirname |xargs dirname |xargs dirname`

$ echo $DIR
/home

Get Shared Preferences Color Code in String then Convert to integer and add layout-background color:

    sharedPreferences = getSharedPreferences(mypref, Context.MODE_PRIVATE);
    String sw=sharedPreferences.getString(name, "");
    relativeLayout.setBackgroundColor(Color.parseColor(sw));

Using the request module solved the issue.

// Include the request library for Node.js   
var request = require('request');
//  Basic Authentication credentials   
var username = "vinod"; 
var password = "12345";
var authenticationHeader = "Basic " + new Buffer(username + ":" + password).toString("base64");
request(   
{
url : "https://133-70-97-54-43.sample.com/feedSample/Query_Status_View/Query_Status/Output1?STATUS=Joined%20school",
headers : { "Authorization" : authenticationHeader }  
},
 function (error, response, body) {
 console.log(body); }  );         

I think you can use MDC to change logging level programmatically. The code below is an example to change logging level on current thread. This approach does not create dependency to logback implementation (SLF4J API contains MDC).

<configuration>
  <turboFilter class="ch.qos.logback.classic.turbo.DynamicThresholdFilter">
    <Key>LOG_LEVEL</Key>
    <DefaultThreshold>DEBUG</DefaultThreshold>
    <MDCValueLevelPair>
      <value>TRACE</value>
      <level>TRACE</level>
    </MDCValueLevelPair>
    <MDCValueLevelPair>
      <value>DEBUG</value>
      <level>DEBUG</level>
    </MDCValueLevelPair>
    <MDCValueLevelPair>
      <value>INFO</value>
      <level>INFO</level>

Swift initializer extension on NSAttributedString

My inclination was to add this as an extension to NSAttributedString rather than String. I tried it as a static extension and an initializer. I prefer the initializer which is what I've included below.

Swift 4

internal convenience init?(html: String) {
    guard let data = html.data(using: String.Encoding.utf16, allowLossyConversion: false) else {
        return nil
    }

    guard let attributedString = try?  NSAttributedString(data: data, options: [.documentType: NSAttributedString.DocumentType.html, .characterEncoding: String.Encoding.utf8.rawValue], documentAttributes: nil) else {
        return nil
    }

    self.init(attributedString: attributedString)
}

Swift 3

extension NSAttributedString {

internal convenience init?(html: String) {
    guard let data = html.data(using: String.Encoding.utf16, allowLossyConversion: false) else {
        return nil
    }

    guard let attributedString = try? NSMutableAttributedString(data: data, options: [NSAttributedString.DocumentReadingOptionKey.documentType: NSAttributedString.DocumentType.html], documentAttributes: nil) else {
        return nil
    }

    self.init(attributedString: attributedString)
}
}

Example

let html = "<b>Hello World!</b>"
let attributedString = NSAttributedString(html: html)

The other reason can be a firewall. We had same issue even with

jupyter notebook --ip xx.xx.xx.xxx --port xxxx.

Then it turns out to be a firewall on our new centOS7.

I wrote a function to do this because I like my code to tell me if something is wrong. This function will explicitly tell you which column names don't match and if you have a type mismatch. Then it will do its best to combine the data.frames anyway. The limitation is that you can only combine two data.frames at a time.

### combines data frames (like rbind) but by matching column names
# columns without matches in the other data frame are still combined
# but with NA in the rows corresponding to the data frame without
# the variable
# A warning is issued if there is a type mismatch between columns of
# the same name and an attempt is made to combine the columns
combineByName <- function(A,B) {
    a.names <- names(A)
    b.names <- names(B)
    all.names <- union(a.names,b.names)

javapackager

The Java Packager tool compiles, packages, and prepares Java and JavaFX applications for distribution. The javapackager command is the command-line version.

– Oracle's documentation

The javapackager utility ships with the JDK. It can generate .exe files with the -native exe flag, among many other things.

WinRun4J

WinRun4j is a java launcher for windows. It is an alternative to javaw.exe and provides the following benefits:

• Uses an INI file for specifying classpath, main class, vm args, program args.
• Custom executable name that appears in task manager.
• Additional JVM args for more flexible memory use.
• Built-in icon replacer for custom icon.
• [more bullet points follow]

– WinRun4J's webpage

WinRun4J is an open source utility. It has many features.

packr

Packages your JAR, assets and a JVM for distribution on Windows, Linux and Mac OS X, adding a native executable file to make it appear like a native app. Packr is most suitable for GUI applications.

– packr README

packr is another open source tool.

JSmooth

JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself.

– JSmooth's website

JSmooth is open source and has features, but it is very old. The last release was in 2007.

JexePack

JexePack is a command line tool (great for automated scripting) that allows you to package your Java application (class files), optionally along with its resources (like GIF/JPG/TXT/etc), into a single compressed 32-bit Windows EXE, which runs using Sun's Java Runtime Environment. Both console and windowed applications are supported.

– JexePack's website

JexePack is trialware. Payment is required for production use, and exe files created with this tool will display "reminders" without payment. Also, the last release was in 2013.

InstallAnywhere

InstallAnywhere makes it easy for developers to create professional installation software for any platform. With InstallAnywhere, you’ll adapt to industry changes quickly, get to market faster and deliver an engaging customer experience. And know the vulnerability of your project’s OSS components before you ship.

– InstallAnywhere's website

InstallAnywhere is a commercial/enterprise package that generates installers for Java-based programs. It's probably capable of creating .exe files.

Executable JAR files

As an alternative to .exe files, you can create a JAR file that automatically runs when double-clicked, by adding an entry point to the JAR manifest.

For more information

An excellent source of information on this topic is Excelsior's article "Convert Java to EXE – Why, When, When Not and How".

See also the companion article "Best JAR to EXE Conversion Tools, Free and Commercial".

docker ps -a to get container ids then docker exec -it psql -U -W

I'm not sure what problem you are solving, but when I have two side by side containers that need to be the same height, I run a little javascript on page load that finds the maximum height of the two and explicitly sets the other to the same height. It seems to me that height: 100% might just mean "make it the size needed to fully contain the content" when what you really want is "make both the size of the largest content."

Note: you'll need to resize them again if anything happens on the page to change their height -- like a validation summary being made visible or a collapsible menu opening.

Adding processData: false to the $.ajax options will fix this issue.

In general, in C++ functions have to be declared before you call them. So sometime before the definition of getSkewNormal(), the compiler needs to see the declaration:

double integrate (double start, double stop, int numSteps, Evaluatable evalObj);

Mostly what people do is put all the declarations (only) in the header file, and put the actual code -- the definitions of the functions and methods -- into a separate source (*.cc or *.cpp) file. This neatly solves the problem of needing all the functions to be declared.

in the example below I exclude

spring-boot-starter-tomcat

compile("org.springframework.boot:spring-boot-starter-web") {
     //by both name and group
     exclude group: 'org.springframework.boot', module: 'spring-boot-starter-tomcat' 
}

It is not possible. §2.3 says that "." is an unreserved character and that "URIs that differ in the replacement of an unreserved character with its corresponding percent-encoded US-ASCII octet are equivalent". Therefore, /%2E%2E/ is the same as /../, and that will get normalized away.

(This is a combination of an answer by bobince and a comment by slowpoison.)

You probably want to create a type by using the Folding Pattern:

    // Here is the constructor section.
    var myType = function () {
        var N = {}, // Enclosed (private) members are here.
            X = this; // Exposed (public) members are here.

        (function ENCLOSED_FIELDS() {
            N.toggle = false;
            N.text = '';
        }());

        (function EXPOSED_FIELDS() {
            X.count = 0;
            X.numbers = [1, 2, 3];
        }());

        // The properties below have access to the enclosed fields.
        // Careful with functions exposed within the closure of the
        // constructor, each new instance will have it's own copy.
        (function EXPOSED_PROPERTIES_WITHIN_CONSTRUCTOR() {
            Object.defineProperty(X, 'toggle', {
                get: function () {
                    var before = N.toggle;
                    N.toggle = !N.toggle;
                    return before;
                }
            });

            Object.defineProperty(X, 'text', {
                get: function () {
                    return N.text;
                },
                set: function (value) {
                    N.text = value;
                }
            });
        }());
    };

    // Here is the prototype section.
    (function PROTOTYPE() {
        var P = myType.prototype;

        (function EXPOSED_PROPERTIES_WITHIN_PROTOTYPE() {
            Object.defineProperty(P, 'numberLength', {
                get: function () {
                    return this.numbers.length;
                }
            });
        }());

        (function EXPOSED_METHODS() {
            P.incrementNumbersByCount = function () {
                var i;
                for (i = 0; i < this.numbers.length; i++) {
                    this.numbers[i] += this.count;
                }
            };
            P.tweak = function () {
                if (this.toggle) {
                    this.count++;
                }
                this.text = 'tweaked';
            };
        }());
    }());

That code will give you a type called myType. It will have internal private fields called toggle and text. It will also have these exposed members: the fields count and numbers; the properties toggle, text and numberLength; the methods incrementNumbersByCount and tweak.

The Folding Pattern is fully detailed here: Javascript Folding Pattern

From Effective Go:

Constants in Go are just that—constant. They are created at compile time, even when defined as locals in functions, and can only be numbers, characters (runes), strings or booleans. Because of the compile-time restriction, the expressions that define them must be constant expressions, evaluatable by the compiler. For instance, 1<<3 is a constant expression, while math.Sin(math.Pi/4) is not because the function call to math.Sin needs to happen at run time.

Slices and arrays are always evaluated during runtime:

var TestSlice = []float32 {.03, .02}
var TestArray = [2]float32 {.03, .02}
var TestArray2 = [...]float32 {.03, .02}

[...] tells the compiler to figure out the length of the array itself. Slices wrap arrays and are easier to work with in most cases. Instead of using constants, just make the variables unaccessible to other packages by using a lower case first letter:

var ThisIsPublic = [2]float32 {.03, .02}
var thisIsPrivate = [2]float32 {.03, .02}

thisIsPrivate is available only in the package it is defined. If you need read access from outside, you can write a simple getter function (see Getters in golang).

In the spirit of a DVCS (as in "Distributed"), you don't cancel something you have published:
Pull requests are essentially patches you have send (normally by email, here by GitHub webapp), and you wouldn't cancel an email either ;)

But since the GitHub Pull Request system also includes a discussion section, that would be there that you could voice your concern to the recipient of those changes, asking him/her to disregards 29 of your 30 commits.

Finally, remember:

• a/ you have a preview section when making a pull request, allowing you to see the number of commits about to be included in it, and to review their diff.
• b/ it is preferable to rebase the work you want to publish as pull request on top of the remote branch which will receive said work. Then you can make a pull request which could be safely applied in a fast forward manner by the recipient.

That being said, since January 2011 ("Refreshed Pull Request Discussions"), and mentioned in the answer above, you can close a pull request in the comments.
Look for that "Comment and Close" button at the bottom of the discussion page:

There are listed the packages you need. So, with:

# dpkg -l | grep libcv2
# dpkg -l | grep libhighgui2

and more listed in the url you can find which packages are installed.

With

# dpkg -L libcv2

you can check where are installed

This operative is used for all debian packages.

Firstly, in general:

If these .h files are indeed typical C-style header files (as opposed to being something completely different that just happens to be named with .h extension), then no, there's no reason to "compile" these header files independently. Header files are intended to be included into implementation files, not fed to the compiler as independent translation units.

Since a typical header file usually contains only declarations that can be safely repeated in each translation unit, it is perfectly expected that "compiling" a header file will have no harmful consequences. But at the same time it will not achieve anything useful.

Basically, compiling hello.h as a standalone translation unit equivalent to creating a degenerate dummy.c file consisting only of #include "hello.h" directive, and feeding that dummy.c file to the compiler. It will compile, but it will serve no meaningful purpose.

Secondly, specifically for GCC:

Many compilers will treat files differently depending on the file name extension. GCC has special treatment for files with .h extension when they are supplied to the compiler as command-line arguments. Instead of treating it as a regular translation unit, GCC creates a precompiled header file for that .h file.

You can read about it here: http://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html

So, this is the reason you might see .h files being fed directly to GCC.

Use parentheses to group the individual branches:

IF EXIST D:\RPS_BACKUP\backups_to_zip\ (goto zipexist) else goto zipexistcontinue

In your case the parser won't ever see the else belonging to the if because goto will happily accept everything up to the end of the command. You can see a similar issue when using echo instead of goto.

Also using parentheses will allow you to use the statements directly without having to jump around (although I wasn't able to rewrite your code to actually use structured programming techniques; maybe it's too early or it doesn't lend itself well to block structures as the code is right now).

FirefoxProfile profile = new FirefoxProfile();
String PROXY = "xx.xx.xx.xx:xx";
OpenQA.Selenium.Proxy proxy = new OpenQA.Selenium.Proxy();
proxy.HttpProxy=PROXY;
proxy.FtpProxy=PROXY;
proxy.SslProxy=PROXY;
profile.SetProxyPreferences(proxy);
FirefoxDriver driver = new FirefoxDriver(profile);

It is for C#

The in operator only works on objects. You are using it on a string. Make sure your value is an object before you using $.each. In this specific case, you have to parse the JSON:

$.each(JSON.parse(myData), ...);

Try this:

setAttribute("hidden", true);

Posting another axios example of an axios.post request that uses additional configuration options and custom headers.

};_x000D_
_x000D_

  }_x000D_
};_x000D_
_x000D_
axios.post('http://<host>:<port>/<path>', postData, axiosConfig)_x000D_

})_x000D_
.catch((err) => {_x000D_
  console.log("AXIOS ERROR: ", err);_x000D_
})

Examples

Given the string foobarbarfoo:

bar(?=bar)     finds the 1st bar ("bar" which has "bar" after it)
bar(?!bar)     finds the 2nd bar ("bar" which does not have "bar" after it)
(?<=foo)bar    finds the 1st bar ("bar" which has "foo" before it)
(?<!foo)bar    finds the 2nd bar ("bar" which does not have "foo" before it)

You can also combine them:

(?<=foo)bar(?=bar)    finds the 1st bar ("bar" with "foo" before it and "bar" after it)

Definitions

Look ahead positive (?=)

Find expression A where expression B follows:

A(?=B)

Look ahead negative (?!)

Find expression A where expression B does not follow:

A(?!B)

Look behind positive (?<=)

Find expression A where expression B precedes:

(?<=B)A

Look behind negative (?<!)

Find expression A where expression B does not precede:

(?<!B)A

Atomic groups (?>)

An atomic group exits a group and throws away alternative patterns after the first matched pattern inside the group (backtracking is disabled).

• (?>foo|foot)s applied to foots will match its 1st alternative foo, then fail as s does not immediately follow, and stop as backtracking is disabled

A non-atomic group will allow backtracking; if subsequent matching ahead fails, it will backtrack and use alternative patterns until a match for the entire expression is found or all possibilities are exhausted.

• (foo|foot)s applied to foots will:

  1. match its 1st alternative foo, then fail as s does not immediately follow in foots, and backtrack to its 2nd alternative;
  2. match its 2nd alternative foot, then succeed as s immediately follows in foots, and stop.

Events are pretty easy in C#, but the MSDN docs in my opinion make them pretty confusing. Normally, most documentation you see discusses making a class inherit from the EventArgs base class and there's a reason for that. However, it's not the simplest way to make events, and for someone wanting something quick and easy, and in a time crunch, using the Action type is your ticket.

Creating Events & Subscribing To Them

1. Create your event on your class right after your class declaration.

public event Action<string,string,string,string>MyEvent;

2. Create your event handler class method in your class.

private void MyEventHandler(string s1,string s2,string s3,string s4)
{
  Console.WriteLine("{0} {1} {2} {3}",s1,s2,s3,s4);
}

3. Now when your class is invoked, tell it to connect the event to your new event handler. The reason the += operator is used is because you are appending your particular event handler to the event. You can actually do this with multiple separate event handlers, and when an event is raised, each event handler will operate in the sequence in which you added them.

class Example
{
  public Example() // I'm a C# style class constructor
  {
    MyEvent += new Action<string,string,string,string>(MyEventHandler);
  }
}

4. Now, when you're ready, trigger (aka raise) the event somewhere in your class code like so:

MyEvent("wow","this","is","cool");

The end result when you run this is that the console will emit "wow this is cool". And if you changed "cool" with a date or a sequence, and ran this event trigger multiple times, you'd see the result come out in a FIFO sequence like events should normally operate.

In this example, I passed 4 strings. But you could change those to any kind of acceptable type, or used more or less types, or even remove the <...> out and pass nothing to your event handler.

And, again, if you had multiple custom event handlers, and subscribed them all to your event with the += operator, then your event trigger would have called them all in sequence.

Identifying Event Callers

But what if you want to identify the caller to this event in your event handler? This is useful if you want an event handler that reacts with conditions based on who's raised/triggered the event. There are a few ways to do this. Below are examples that are shown in order by how fast they operate:

Option 1. (Fastest) If you already know it, then pass the name as a literal string to the event handler when you trigger it.

Option 2. (Somewhat Fast) Add this into your class and call it from the calling method, and then pass that string to the event handler when you trigger it:

private static string GetCaller([System.Runtime.CompilerServices.CallerMemberName] string s = null) => s;

Option 3. (Least Fast But Still Fast) In your event handler when you trigger it, get the calling method name string with this:

string callingMethod = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod().ReflectedType.Name.Split('<', '>')[1];

Unsubscribing From Events

You may have a scenario where your custom event has multiple event handlers, but you want to remove one special one out of the list of event handlers. To do so, use the -= operator like so:

MyEvent -= MyEventHandler;

A word of minor caution with this, however. If you do this and that event no longer has any event handlers, and you trigger that event again, it will throw an exception. (Exceptions, of course, you can trap with try/catch blocks.)

Clearing All Events

Okay, let's say you're through with events and you don't want to process any more. Just set it to null like so:

MyEvent = null;

The same caution for Unsubscribing events is here, as well. If your custom event handler no longer has any events, and you trigger it again, your program will throw an exception.

As of the time of this writing, Swift natively supports comparing Dates with all comparison operators (i.e. <, <=, ==, >=, and >). You can also compare optional Dates but are limited to <, ==, and >. If you need to compare two optional dates using <= or >=, i.e.

let date1: Date? = ...
let date2: Date? = ...
if date1 >= date2 { ... }

You can overload the <= and >=operators to support optionals:

func <= <T: Comparable>(lhs: T?, rhs: T?) -> Bool {
    return lhs == rhs || lhs < rhs
}

func >= <T: Comparable>(lhs: T?, rhs: T?) -> Bool {
    return lhs == rhs || lhs > rhs
}

Here's a solution for more extreme cases:

if [ `command | head -c1 | wc -c` -gt 0 ]; then ...; fi

This will work

• for all Bourne shells;
• if the command output is all zeroes;
• efficiently regardless of output size;

however,

• the command or its subprocesses will be killed once anything is output.

np.isnan can be applied to NumPy arrays of native dtype (such as np.float64):

In [99]: np.isnan(np.array([np.nan, 0], dtype=np.float64))
Out[99]: array([ True, False], dtype=bool)

but raises TypeError when applied to object arrays:

In [96]: np.isnan(np.array([np.nan, 0], dtype=object))
TypeError: ufunc 'isnan' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

Since you have Pandas, you could use pd.isnull instead -- it can accept NumPy arrays of object or native dtypes:

In [97]: pd.isnull(np.array([np.nan, 0], dtype=float))
Out[97]: array([ True, False], dtype=bool)

In [98]: pd.isnull(np.array([np.nan, 0], dtype=object))
Out[98]: array([ True, False], dtype=bool)

Note that None is also considered a null value in object arrays.

Assuming doc is your instance of org.w3c.dom.Document:

TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
StringWriter writer = new StringWriter();
transformer.transform(new DOMSource(doc), new StreamResult(writer));
String output = writer.getBuffer().toString().replaceAll("\n|\r", "");

Swift 5:

navigationController?.viewControllers.removeAll(where: { (vc) -> Bool in
    if vc.isKind(of: MyViewController.self) || vc.isKind(of: MyViewController2.self) {
        return false
    } else {
        return true
    }
})

Perhaps you try this solution:

#define QUANTIDISCHI 6
#define QUDI(x) #x
#define QUdi(x) QUDI(x)
. . . 
. . .
unsigned char TheNumber[] = "QUANTIDISCHI = " QUdi(QUANTIDISCHI) "\n";

You should call srand() before calling rand to initialize the random number generator.

Either call it with a specific seed, and you will always get the same pseudo-random sequence

#include <stdlib.h>

int main ()
{
  srand ( 123 );
  int random_number = rand();
  return 0;
}

or call it with a changing sources, ie the time function

#include <stdlib.h>
#include <time.h>

int main ()
{
  srand ( time(NULL) );
  int random_number = rand();
  return 0;
}

In response to Moon's Comment rand() generates a random number with an equal probability between 0 and RAND_MAX (a macro pre-defined in stdlib.h)

You can then map this value to a smaller range, e.g.

int random_value = rand(); //between 0 and RAND_MAX

//you can mod the result
int N = 33;
int rand_capped = random_value % N;  //between 0 and 32
int S = 50;
int rand_range = rand_capped + S; //between 50 and 82

//you can convert it to a float
float unit_random = random_value / (float) RAND_MAX; //between 0 and 1 (floating point)

This might be sufficient for most uses, but its worth pointing out that in the first case using the mod operator introduces a slight bias if N does not divide evenly into RAND_MAX+1.

Random number generators are interesting and complex, it is widely said that the rand() generator in the C standard library is not a great quality random number generator, read (http://en.wikipedia.org/wiki/Random_number_generation for a definition of quality).

http://en.wikipedia.org/wiki/Mersenne_twister (source http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html ) is a popular high quality random number generator.

Also, I am not aware of arc4rand() or random() so I cannot comment.

This isn't a direct answer but may provide a more efficient alternative for your consideration. Which is that Google Sheets has several built in Regex Functions these can be very convenient and help circumvent some of the technical procedures in Excel. Obviously there are some advantages to using Excel on your PC but for the large majority of users Google Sheets will offer an identical experience and may offer some benefits in portability and sharing of documents.

They offer

REGEXEXTRACT: Extracts matching substrings according to a regular expression.

REGEXREPLACE: Replaces part of a text string with a different text string using regular expressions.

SUBSTITUTE: Replaces existing text with new text in a string.

REPLACE: Replaces part of a text string with a different text string.

You can type these directly into a cell like so and will produce whatever you'd like

=REGEXMATCH(A2, "[0-9]+")

They also work quite well in combinations with other functions such as IF statements like so:

Hopefully this provides a simple workaround for users who feel taunted by the VBS component of Excel.

basically hidden fields will be more useful and advantages to use with multi step form. we can use hidden fields to pass one step information to next step using hidden and keep it forwarding till the end step.

1. CSRF tokens.

Cross-site request forgery is a very common website vulnerability. Requiring a secret, user-specific token in all form submissions will prevent CSRF attacks since attack sites cannot guess what the proper token is and any form submissions they perform on the behalf of the user will always fail.

2. Save state in multi-page forms.

If you need to store what step in a multi-page form the user is currently on, use hidden input fields. The user doesn't need to see this information, so hide it in a hidden input field.

General rule: Use the field to store anything that the user doesn't need to see, but that you want to send to the server on form submission.

I had the similar issue and the above examples doesn't help me to read properties. I have posted the complete class which will help you to read properties values from application.properties file in SpringBoot application in the below link.

Spring Boot - Environment @Autowired throws NullPointerException

Hide scroll bar for Mozilla.

  overflow: -moz-hidden-unscrollable;

i think this add new property in desired type without having to set a primitive value, like when property defined in class definition

var x = new ExpandoObject();
x.NewProp = default(string)

Use and empty() whit negation (for test if not empty)

if(!empty($_GET['id'])) {
    // if get id is not empty
}

== checks to see if they are actually the same object in memory (which confusingly sometimes is true, since they may both be from the pool), where as equals() is overridden by java.lang.String to check each character to ensure true equality. So therefore, equals() is what you want.

You are not selecting multiple indexes with PriceList[0][1][2][3][4][5][6] , instead each [] is going into a sub index.

Try this

PizzaChange=float(input("What would you like the new price for all standard pizzas to be? "))      
PriceList[0:7]=[PizzaChange]*7  
PriceList[7:11]=[PizzaChange+3]*4

You can probably encode the tar file in Base64. Base 64 will give you a pure ASCII representation of the file that you can store in a plain text file. Then you can retrieve the tar file by decoding the text back.

You do something like:

require 'base64'

file_contents = Base64.encode64(tar_file_data)

Have look at the Base64 Rubydocs to get a better idea.

Have a go with this, as this is how I would do it :)

There is a handy bash utility - dos2unix - which is a DOS/MAC to UNIX text file format converter, that if not already installed on your distro, should be able to be easily installed via a package manager. dos2unix man page

Be aware that this property isn't as useful as many people think it is. Just because your app is running on a Windows machine, for example, doesn't mean the file it's reading will be using Windows-style line separators. Many web pages contain a mixture of "\n" and "\r\n", having been cobbled together from disparate sources. When you're reading text as a series of logical lines, you should always look for all three of the major line-separator styles: Windows ("\r\n"), Unix/Linux/OSX ("\n") and pre-OSX Mac ("\r").

When you're writing text, you should be more concerned with how the file will be used than what platform you're running on. For example, if you expect people to read the file in Windows Notepad, you should use "\r\n" because it only recognizes the one kind of separator.

Here is another simple method using del in one liner:

for key in e_keys: del your_dict[key]

e_keys is the list of the keys to be excluded. It will update your dict rather than giving you a new one.

If you want a new output dict, then make a copy of the dict before deleting:

new_dict = your_dict.copy()           #Making copy of dict

for key in e_keys: del new_dict[key]

Transaction Isolation and Transaction Propagation although related but are clearly two very different concepts. In both cases defaults are customized at client boundary component either by using Declarative transaction management or Programmatic transaction management. Details of each isolation levels and propagation attributes can be found in reference links below.

Transaction Isolation

For given two or more running transactions/connections to a database, how and when are changes made by queries in one transaction impact/visible to the queries in a different transaction. It also related to what kind of database record locking will be used to isolate changes in this transaction from other transactions and vice versa. This is typically implemented by database/resource that is participating in transaction.

.

Transaction Propagation

In an enterprise application for any given request/processing there are many components that are involved to get the job done. Some of this components mark the boundaries (start/end) of a transaction that will be used in respective component and it's sub components. For this transactional boundary of components, Transaction Propogation specifies if respective component will or will not participate in transaction and what happens if calling component already has or does not have a transaction already created/started. This is same as Java EE Transaction Attributes. This is typically implemented by the client transaction/connection manager.

Reference:

• Spring Transaction Management

• Wiki Transaction Isolation (database systems)

• Oracle on Transaction Isolation Levels

• Java EE Transaction Attributes (propagation)

• Spring Framework Transaction propagation

Flask-Restful 0.3.6 the Request Parsing recommend marshmallow

marshmallow is an ORM/ODM/framework-agnostic library for converting complex datatypes, such as objects, to and from native Python datatypes.

A simple marshmallow example is showing below.

from marshmallow import Schema, fields

class UserSchema(Schema):
    name = fields.Str()
    email = fields.Email()
    created_at = fields.DateTime()

from marshmallow import pprint

user = User(name="Monty", email="[email protected]")
schema = UserSchema()
result = schema.dump(user)
pprint(result)
# {"name": "Monty",
#  "email": "[email protected]",
#  "created_at": "2014-08-17T14:54:16.049594+00:00"}

The core features contain

Declaring Schemas
Serializing Objects (“Dumping”)
Deserializing Objects (“Loading”)
Handling Collections of Objects
Validation
Specifying Attribute Names
Specifying Serialization/Deserialization Keys
Refactoring: Implicit Field Creation
Ordering Output
“Read-only” and “Write-only” Fields
Specify Default Serialization/Deserialization Values
Nesting Schemas
Custom Fields

Try this:

Get-ChildItem C:\windows\System32 -Include *.txt -Recurse | select -ExpandProperty FullName

If someone was looking for a way to remove all instances of repeated values, see "How can I efficiently extract repeated elements in a Ruby array?".

a = [1, 2, 2, 3]
counts = Hash.new(0)
a.each { |v| counts[v] += 1 }
p counts.select { |v, count| count == 1 }.keys # [1, 3]

Here is a list of this you should look into when dealing with PHPMailer:

1. Enable openSSL by un-commenting extension=php_openssl.dll in your PHP.ini
2. Use $mail->SMTPSecure = 'tls'; and $mail->Port = 587;
3. Enable debugging for if you are going wrong somewhere else like incorrect username and password etc.

Anyone can define "token_type" as an OAuth 2.0 extension, but currently "bearer" token type is the most common one.

https://tools.ietf.org/html/rfc6750

Basically that's what Facebook is using. Their implementation is a bit behind from the latest spec though.

If you want to be more secure than Facebook (or as secure as OAuth 1.0 which has "signature"), you can use "mac" token type.

However, it will be hard way since the mac spec is still changing rapidly.

https://tools.ietf.org/html/draft-ietf-oauth-v2-http-mac-05

This little example shows how the $rootScope emit a event that will be listen by a children scope in another controller.

(function(){


angular
  .module('ExampleApp',[]);

angular
  .module('ExampleApp')
  .controller('ExampleController1', Controller1);

Controller1.$inject = ['$rootScope'];

function Controller1($rootScope) {
  var vm = this, 
      message = 'Hi my children scope boy';

  vm.sayHi = sayHi;

  function sayHi(){
    $rootScope.$broadcast('greeting', message);
  }

}

angular
  .module('ExampleApp')
  .controller('ExampleController2', Controller2);

Controller2.$inject = ['$scope'];

function Controller2($scope) {
  var vm = this;

  $scope.$on('greeting', listenGreeting)

  function listenGreeting($event, message){
    alert(['Message received',message].join(' : '));
  }

}


})();

The answer of @gayathri bottom explain technically the differences of all those methods in the scope angular concept and their implementations $scope and $rootScope.

Update or Delete with sql transaction

 private void SQLTransaction() {
   try {
     string sConnectionString = "My Connection String";
     string query = "UPDATE [dbo].[MyTable] SET ColumnName = '{0}' WHERE ID = {1}";

     SqlConnection connection = new SqlConnection(sConnectionString);
     SqlCommand command = connection.CreateCommand();
     connection.Open();
     SqlTransaction transaction = connection.BeginTransaction("");
     command.Transaction = transaction;
     try {
       foreach(DataRow row in dt_MyData.Rows) {
         command.CommandText = string.Format(query, row["ColumnName"].ToString(), row["ID"].ToString());
         command.ExecuteNonQuery();
       }
       transaction.Commit();
     } catch (Exception ex) {
       transaction.Rollback();
       MessageBox.Show(ex.Message, "Error");
     }
   } catch (Exception ex) {
     MessageBox.Show("Problem connect to database.", "Error");
   }
 }

Using this code you can take input till pressing enter of your keyboard.

char ch[100];
int i;
for (i = 0; ch[i] != '\n'; i++)
{
    scanf("%c ", &ch[i]);
}

This is due to Morphia jar not being part of your output war/jar. Eclipse or local build includes them as part of classpath, but remote builds or auto/scheduled build don't consider them part of classpath.

You can include dependent jars using plugin.

Add below snippet into your pom's plugins section

    <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <version>3.0.0</version>
        <configuration>
            <descriptorRefs>
                <descriptorRef>jar-with-dependencies</descriptorRef>
            </descriptorRefs>
        </configuration>
    </plugin>

Yes, it's the right way. You can use images in the Resource file using a path:

<StackPanel Orientation="Horizontal">
    <CheckBox  Content="{Binding Nname}" IsChecked="{Binding IsChecked}"/>
    <Image Source="E:\SWorking\SharePointSecurityApps\SharePointSecurityApps\SharePointSecurityApps.WPF\Images\sitepermission.png"/>
    <TextBlock Text="{Binding Path=Title}"></TextBlock>
</StackPanel>

Using executeUpdate() on the Query API is faster because it bypasses the persistent context .However , by-passing persistent context would cause the state of instance in the memory and the actual values of that record in the DB are not synchronized.

Consider the following example :

 Employee employee= (Employee)entityManager.find(Employee.class , 1);
 entityManager
     .createQuery("update Employee set name = \'xxxx\' where id=1")
     .executeUpdate();

After flushing, the name in the DB is updated to the new value but the employee instance in the memory still keeps the original value .You have to call entityManager.refresh(employee) to reload the updated name from the DB to the employee instance.It sounds strange if your codes still have to manipulate the employee instance after flushing but you forget to refresh() the employee instance as the employee instance still contains the original values.

Normally , executeUpdate() is used in the bulk update process as it is faster due to bypassing the persistent context

The right way to update an entity is that you just set the properties you want to updated through the setters and let the JPA to generate the update SQL for you during flushing instead of writing it manually.

   Employee employee= (Employee)entityManager.find(Employee.class ,1);
   employee.setName("Updated Name");

Try this:

alerts.splice(0,0,{"app":"goodbyeworld","message":"cya"});

Works pretty well, it'll add it to the start of the array.

ANSI compliant, without cursor

PRINT ('1.a. Delete stored procedures ' + CONVERT( VARCHAR(19), GETDATE(), 121));
GO
DECLARE @procedure NVARCHAR(max)
DECLARE @n CHAR(1)
SET @n = CHAR(10)
SELECT @procedure = isnull( @procedure + @n, '' ) +
'DROP PROCEDURE [' + schema_name(schema_id) + '].[' + name + ']'
FROM sys.procedures

EXEC sp_executesql @procedure
PRINT ('1.b. Stored procedures deleted ' + CONVERT( VARCHAR(19), GETDATE(), 121));
GO

This worked for me:

$('#fileInput').val('');

If you need to access "the first property of an object", it might mean that there is something wrong with your logic. The order of an object's properties should not matter.

(Strictly speaking not an answer to the question, but in my experience likely to be useful when looking for class variables)

A class method can often play many of the roles a class variable would in other languages (e.g. changed configuration during tests):

@interface MyCls: NSObject
+ (NSString*)theNameThing;
- (void)doTheThing;
@end
@implementation
+ (NSString*)theNameThing { return @"Something general"; }
- (void)doTheThing {
  [SomeResource changeSomething:[self.class theNameThing]];
}
@end

@interface MySpecialCase: MyCls
@end
@implementation
+ (NSString*)theNameThing { return @"Something specific"; }
@end

Now, an object of class MyCls calls Resource:changeSomething: with the string @"Something general" upon a call to doTheThing:, but an object derived from MySpecialCase with the string @"Something specific".

You can get the First and Last Date in the current month by following the code:

var dateNow = new Date();
var firstDate = new Date(dateNow.getFullYear(), dateNow.getMonth(), 1);
var lastDate = new Date(dateNow.getFullYear(), dateNow.getMonth() + 1, 0);

or if you want to format the date in your custom format then you can use moment js

var dateNow= new Date();
var firstDate=moment(new Date(dateNow.getFullYear(),dateNow.getMonth(), 1)).format("DD-MM-YYYY");
var currentDate = moment(new Date()).format("DD-MM-YYYY"); //to get the current date var lastDate = moment(new Date(dateNow.getFullYear(), dateNow.getMonth() + 1, 0)).format("DD-MM-YYYY"); //month last date

If you're using Tortoise SVN, you should be able to revert changes from just that revision into your working copy (effectively performing a reverse-merge), then do another commit to re-add the file. Steps to follow are:

1. Browse to folder in working copy where you deleted the file.
2. Go to repo-browser.
3. Browse to revision where you deleted the file.
4. In the change list, find the file you deleted.
5. Right click on the file and go to "Revert changes from this revision".
6. This will restore the file to your working copy, keeping history.
7. Commit the file to add it back into your repository.

Quote from the book: Introduction to Information Retrieval

Cache

We want to keep as much data as possible in memory, especially those data that we need to access frequently. We call the technique of keeping frequently used disk data in main memory caching.

Buffer

Operating systems generally read and write entire blocks. Thus, reading a single byte from disk can take as much time as reading the entire block. Block sizes of 8, 16, 32, and 64 kilobytes (KB) are common. We call the part of main memory where a block being read or written is stored a buffer.

I found the best solution if you have nested numpy arrays in a dictionary:

import json
import numpy as np

class NumpyEncoder(json.JSONEncoder):
    """ Special json encoder for numpy types """
    def default(self, obj):
        if isinstance(obj, np.integer):
            return int(obj)
        elif isinstance(obj, np.floating):
            return float(obj)
        elif isinstance(obj, np.ndarray):
            return obj.tolist()
        return json.JSONEncoder.default(self, obj)

dumped = json.dumps(data, cls=NumpyEncoder)

with open(path, 'w') as f:
    json.dump(dumped, f)

Thanks to this guy.

The align-items, or respectively align-content attribute controls this behaviour.

align-items defines the items' positioning perpendicularly to flex-direction.

The default flex-direction is row, therfore vertical placement can be controlled with align-items.

There is also the align-self attribute to control the alignment on a per item basis.

#a {_x000D_
  display:flex;_x000D_
_x000D_
  align-items:flex-start;_x000D_
  align-content:flex-start;_x000D_

  }_x000D_

  align-self:stretch;_x000D_
 }

<div id="a">_x000D_

css-tricks has an excellent article on the topic. I recommend reading it a couple of times.

From JSP

<form method="post" id="myForm" action="someURL">
    <input name="csrfToken" value="5965f0d244b7d32b334eff840...etc" type="hidden">    
</form>

This is the simplest way that worked for me after struggling for 3hrs, just get the token from input hidden field like this and while doing the AJAX request to just need to pass this token in header as follows:-

From Jquery

var token =  $('input[name="csrfToken"]').attr('value'); 

From plain Javascript

var token = document.getElementsByName("csrfToken").value;

Final AJAX Request

$.ajax({
      url: route.url,
      data : JSON.stringify(data),
      method : 'POST',
      headers: {
                    'X-CSRF-Token': token 
               },
      success: function (data) { ...      },
      error: function (data) { ...  }

});

Now you don't need to disable crsf security in web config, and also this will not give you 405( Method Not Allowed) error on console.

Hope this will help people..!!

Not 100%; however, it sounds like the heap is an object or set of allocated space (on RAM) that is built into the functionality of the code either Java itself or more likely functionality from ehcache itself, and the off-heap Ram is there own system as well; however, it sounds like this is one magnitude slower as it is not as organized, meaning it may not use a heap (meaning one long set of space of ram), and instead uses different address spaces likely making it slightly less efficient.

Then of course the next tier lower is hard-drive space itself.

I don't use ehcache, so you may not want to trust me, but that what is what I gathered from their documentation.

First, check if you have internet permission in Manifest file.

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

You can then add following code in onCreate() or initialize() method-

final WebView webview = (WebView) rootView.findViewById(R.id.webview);
        webview.setWebViewClient(new MyWebViewClient());
        webview.getSettings().setBuiltInZoomControls(false);
        webview.getSettings().setSupportZoom(false);
        webview.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        webview.getSettings().setAllowFileAccess(true);
        webview.getSettings().setDomStorageEnabled(true);
        webview.loadUrl(URL);

And write a class to handle callbacks of webview -

public class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
                           //your handling...
                return super.shouldOverrideUrlLoading(view, url);
        }
    }

in same class, you can also use other important callbacks such as -

- onPageStarted()
- onPageFinished()
- onReceivedSslError()

Also, you can add "SwipeRefreshLayout" to enable swipe refresh and refresh the webview.

<android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/swipeRefreshLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <WebView
            android:id="@+id/webview"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </android.support.v4.widget.SwipeRefreshLayout>

And refresh the webview when user swipes screen:

SwipeRefreshLayout mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeRefreshLayout);
            mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
                @Override
                public void onRefresh() {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mSwipeRefreshLayout.setRefreshing(false);
                            webview.reload();
                        }
                    }, 3000);
                }
            });

When I did this for a navigation database built from ARINC424 I did a fair amount of testing and looking back at the code, I used a DECIMAL(18,12) (Actually a NUMERIC(18,12) because it was firebird).

Floats and doubles aren't as precise and may result in rounding errors which may be a very bad thing. I can't remember if I found any real data that had problems - but I'm fairly certain that the inability to store accurately in a float or a double could cause problems

The point is that when using degrees or radians we know the range of the values - and the fractional part needs the most digits.

The MySQL Spatial Extensions are a good alternative because they follow The OpenGIS Geometry Model. I didn't use them because I needed to keep my database portable.

For those who are using Font Awesome version 4.7,

css_selector::before{
content:"\f006";
font-family:"fontawesome";
font-weight:900;
}

The solution is already answered here above (long ago).

But the implicit question "why does it work in FF and IE but not in Chrome and Safari" is found in the error text "Not allowed to load local resource": Chrome and Safari seem to use a more strict implementation of sandboxing (for security reasons) than the other two (at this time 2011).

This applies for local access. In a (normal) server environment (apache ...) the file would simply not have been found.

To consider the timezone also, this one-liner should be good without any library:

new Date().toLocaleString("en-IN", {timeZone: "Asia/Kolkata"}).split(',')[0]

If you have a base or header template that's included everywhere why not include the favicon there with basic HTML?

<link rel="shortcut icon" type="image/png" href="{% static 'favicon.ico' %}"/>

If listOfIds is a list, this will work, but, List.Contains() is a linear search, so this isn't terribly efficient.

You're better off storing the ids you want to look up into a container that is suited for searching, like Set.

List<int> listOfIds = new List(GetListOfIds());
lists.Where(r=>listOfIds.Contains(r.Id));

Here's my console wrapper class. It gives me scope output as well to make life easier. Note the use of localConsole.debug.call() so that localConsole.debug runs in the scope of the calling class, providing access to its toString method.

localConsole = {

    info: function(caller, msg, args) {
        if ( window.console && window.console.info ) {
            var params = [(this.className) ? this.className : this.toString() + '.' + caller + '(), ' + msg];
            if (args) {
                params = params.concat(args);
            }
            console.info.apply(console, params);
        }
    },

    debug: function(caller, msg, args) {
        if ( window.console && window.console.debug ) {
            var params = [(this.className) ? this.className : this.toString() + '.' + caller + '(), ' + msg];
            if (args) {
                params = params.concat(args);
            }
            console.debug.apply(console, params);
        }
    }
};

someClass = {

    toString: function(){
        return 'In scope of someClass';
    },

    someFunc: function() {

        myObj = {
            dr: 'zeus',
            cat: 'hat'
        };

        localConsole.debug.call(this, 'someFunc', 'myObj: ', myObj);
    }
};

someClass.someFunc();

This gives output like so in Firebug:

In scope of someClass.someFunc(), myObj: Object { dr="zeus", more...}

Or Chrome:

In scope of someClass.someFunc(), obj:
Object
cat: "hat"
dr: "zeus"
__proto__: Object

They both track your changes to the collection, just call the SaveChanges() method that should update the DB.

I know this is a rather old question as of now, but I had found the proper solution was that I was not declaring the assembly attribute.

My code is:

using AutoMapper;
...

namespace [...].Controllers
{
    public class HousingTenureTypesController : LookupController<HousingTenureType, LookupTypeModel>
    {
        Mapper.CreateMap<HousingTenureType, LookupTypeModel>().ReverseMap();
    }
    ...
}

This was fixed by adding the following line before my namespace declaration:

[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(HousingTenureTypesController), "AutoMapperStart")]

The full code is:

using AutoMapper;
...

[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(HousingTenureTypesController), "AutoMapperStart")]

namespace [...].Controllers
{
    public class HousingTenureTypesController : LookupController<HousingTenureType, LookupTypeModel>
    {
        Mapper.CreateMap<HousingTenureType, LookupTypeModel>().ReverseMap();
    }
    ...
}

I faced the same problem and now found a way to solve it. First you have to delete the database of the user that you wish to drop. Then the user can be easily deleted.

I created an user named "msf" and struggled a while to delete the user and recreate it. I followed the below steps and Got succeeded.

1) Drop the database

dropdb msf

2) drop the user

dropuser msf

Now I got the user successfully dropped.

I have the same problem that you describe although I'm building up my LatLngBounds as proposed by above. The problem is that things are async and calling map.fitBounds() at the wrong time may leave you with a result like in the Q. The best way I found is to place the call in an idle handler like this:

google.maps.event.addListenerOnce(map, 'idle', function() {
    map.fitBounds(markerBounds);
});

If you want to scroll down to the div (id="div1"). Then you can use this code.

 $('html, body').animate({
     scrollTop: $("#div1").offset().top
 }, 1500);

A one-liner that gives both the offset and the time zone is to simply call toTimeString() on a new Date object. From MDN:

The toTimeString() method returns the time portion of a Date object in human readable form in American English.

The catch is that the timezone is not in the standard IANA format; it's somewhat more user-friendly, than the "continent/city" IANA format. Try it out:

console.log(new Date().toTimeString().slice(9));
console.log(Intl.DateTimeFormat().resolvedOptions().timeZone);
console.log(new Date().getTimezoneOffset() / -60);

In California right now, toTimeString() returns Pacific Daylight Time while the Intl API returns America/Los_Angeles. In Colombia, you'd get Colombia Standard Time, vs. America/Bogota.

Note that many other answers to this question attempt to obtain the same information by calling Date.toString(). That approach is not that reliable, as MDN explains:

Date instances refer to a specific point in time. Calling toString() will return the date formatted in a human readable form in American English. [...] Sometimes it is desirable to obtain a string of the time portion; such a thing can be accomplished with the toTimeString() method.

The toTimeString() method is especially useful because compliant engines implementing ECMA-262 may differ in the string obtained from toString() for Date objects, as the format is implementation-dependent; simple string slicing approaches may not produce consistent results across multiple engines.

The font tag has been deprecated for some time now.

That being said, the reason why both of your tables display with the same font size is that the 'size' attribute only accepts values ranging from 1 - 7. The smallest size is 1. The largest size is 7. The default size is 3. Any values larger than 7 will just display the same as if you had used 7, because 7 is the maximum value allowed.

And as @Alex H said, you should be using CSS for this.

I think using okhttp is the easiest solution. Here you can see an example for POST method, sending a json, and with auth.

val url = "https://example.com/endpoint"

val client = OkHttpClient()

val JSON = MediaType.get("application/json; charset=utf-8")
val body = RequestBody.create(JSON, "{\"data\":\"$data\"}")
val request = Request.Builder()
        .addHeader("Authorization", "Bearer $token")
        .url(url)
        .post(body)
        .build()

val  response = client . newCall (request).execute()

println(response.request())
println(response.body()!!.string())

Remember to add this dependency to your project https://mvnrepository.com/artifact/com.squareup.okhttp3/okhttp

UPDATE: July 7th, 2019 I'm gonna give two examples using latest Kotlin (1.3.41), OkHttp (4.0.0) and Jackson (2.9.9).

Why is everyone complicating this?

The only problem is Math.atan2( x , y)

The corret answer is Math.atan2( y, x)

All they did was mix the variable order for Atan2 causing it to reverse the degree of rotation.

All you had to do was look up the syntax https://www.google.com/amp/s/www.geeksforgeeks.org/java-lang-math-atan2-java/amp/

DOMDocument is a great choice. It's a module specifically designed for creating and manipulating XML documents. You can create a document from scratch, or open existing documents (or strings) and navigate and modify their structures.

$xml = new DOMDocument();
$xml_album = $xml->createElement("Album");
$xml_track = $xml->createElement("Track");
$xml_album->appendChild( $xml_track );
$xml->appendChild( $xml_album );

$xml->save("/tmp/test.xml");

To re-open and write:

$xml = new DOMDocument();
$xml->load('/tmp/test.xml');
$nodes = $xml->getElementsByTagName('Album') ;
if ($nodes->length > 0) {
   //insert some stuff using appendChild()
}

//re-save
$xml->save("/tmp/test.xml");

The default sqlite library that comes with iOS is not compiled using the SQLITE_THREADSAFE macro on. This could be a reason why your code crashes.

The following simply returns 4 as an answer. When you replace the add expressions for strings it returns the first string.

Function StartingMain {
  $a = 1 + 3
  $b = 2 + 5
  $c = 3 + 7
  Return $a
}

Function StartingEnd($b) {
  Write-Host $b
}

StartingEnd(StartingMain)

This can also be done for an array. The example below will return "Text 2"

Function StartingMain {
  $a = ,@("Text 1","Text 2","Text 3")
  Return $a
}

Function StartingEnd($b) {
  Write-Host $b[1]
}

StartingEnd(StartingMain)

Note that you have to call the function below the function itself. Otherwise, the first time it runs it will return an error that it doesn't know what "StartingMain" is.

Here is an SQL request to do that:

Much longer solution, but accounts for the following scenarios:

1. Is the image smaller than the bounding box?
2. Is the Image and the Bounding Box square?
3. Is the Image square and the bounding box isn't
4. Is the image wider and taller than the bounding box
5. Is the image wider than the bounding box

6. Is the image taller than the bounding box

   private Image ResizePhoto(FileInfo sourceImage, int desiredWidth, int desiredHeight)

       var oH = (decimal)original.Height;
       var dW = (decimal)desiredWidth;
       var dH = (decimal)desiredHeight;
   
       //check if image already fits
       if (oW < dW && oH < dH)
           return original; //image fits in bounding box, keep size (center with css) If we made it bigger it would stretch the image resulting in loss of quality.
   
       //check for double squares
       if (oW == oH && dW == dH)
       {
           //image and bounding box are square, no need to calculate aspects, just downsize it with the bounding box

           var nH = oH * r; //will downscale the original image by an aspect ratio to fit in the bounding box at the maximum size within aspect ratio.
           var nW = oW * r;

       else
       {
           if (oW > dW) //image is wider than bounding box
           {
               var r = dW / oW; //one dimension (width) so calculate the aspect ratio between the bounding box width and original image width

You can use select into inside of a PLSQL block such as below.

Declare
  l_variable assignment%rowtype
begin
  select *
  into l_variable
  from assignment;
exception
  when no_data_found then
    dbms_output.put_line('No record avialable')
  when too_many_rows then
   dbms_output.put_line('Too many rows')
end;

This code will only work when there is exactly 1 row in assignment. Usually you will use this kind of code to select a specific row identified by a key number.

Declare
  l_variable assignment%rowtype
begin
  select *
  into l_variable
  from assignment
  where ID=<my id number>;
exception
  when no_data_found then
    dbms_output.put_line('No record avialable')
  when too_many_rows then
   dbms_output.put_line('Too many rows')
end;

To create a Twitter share link with a photo, you first need to tweet out the photo from your Twitter account. Once you've tweeted it out, you need to grab the pic.twitter.com link and place that inside your twitter share url.

note: You won't be able to see the pic.twitter.com url so what I do is use a separate account and hit the retweet button. A modal will pop up with the link inside.

You Twitter share link will look something like this:

<a href="https://twitter.com/home?status=This%20photo%20is%20awesome!%20Check%20it%20out:%20pic.twitter.com/9Ee63f7aVp">Share on Twitter</a>

function myFunction(arg) {
    alert(arg.var1 + ' ' + arg.var2 + ' ' + arg.var3);
}

myFunction ({ var1: "Option 1", var2: "Option 2", var3: "Option 3" });

ES6 is quite powerful in iterating through objects (strings, Array, Map, Set). Let's use a Spread Operator to solve this.

entry = prompt("Enter your name");
var count = [...entry];
console.log(count);

You can make virtualenvwrapper use a custom Python binary instead of the one virtualenvwrapper is run with. To do that you need to use VIRTUALENV_PYTHON variable which is utilized by virtualenv:

$ export VIRTUALENV_PYTHON=/usr/bin/python3
$ mkvirtualenv -a myproject myenv
Running virtualenv with interpreter /usr/bin/python3
New python executable in myenv/bin/python3
Also creating executable in myenv/bin/python
(myenv)$ python

[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.

Instead of imageElement.src = myImage; you should use window.location = myImage;

And even after that the browser will display the image itself. You can right click and use "Save Link" for downloading the image.

In Eclipse if you turn on the option "Escape text when pasting into a string literal" (in Preferences > Java > Editor > Typing) and paste a multi-lined string whithin quotes, it will automatically add " and \n" + for all your lines.

String str = "paste your text here";

They are identical. JPG is simply a holdover from the days of DOS when file extensions were required to be 3 characters long. You can find out more information about the JPEG standard here. A question very similar to this one was asked over at SuperUser, where the accepted answer should give you some more detailed information.

When installing laravel on Ubuntu 18.04, be default PHP 7.3.0RC3 install selected, but laravel and symfony will not install properly complaining about missin php-xml and php-zip, even though they are installed. You need to switch to php 7.1, using the instructions above or,

 sudo update-alternatives --set php /usr/bin/php7.1

now, running laravel new blog, will proceed correctly

Try:

$a1=@(1,2,3,4,5)
$b1=@(1,2,3,4,5,6)
(Compare-Object $a1 $b1).InputObject

Or, you can use:

(Compare-Object $b1 $a1).InputObject

The order doesn't matter.

You can make a text align to the right inside of any element, including labels.

Html:

<label>Text</label>

Css:

label {display:block; width:x; height:y; text-align:right;}

This way, you give a width and height to your label and make any text inside of it align to the right.

To improve answers by @Tommy and @Dima, use the following category to render UIView into UIImage with transparent background and without loss of quality. Working on iOS7. (Or just reuse that method in implementation, replacing self reference with your image)

UIView+RenderViewToImage.h

#import <UIKit/UIKit.h>

@interface UIView (RenderToImage)

- (UIImage *)imageByRenderingView;

@end

UIView+RenderViewToImage.m

#import "UIView+RenderViewToImage.h"

@implementation UIView (RenderViewToImage)

- (UIImage *)imageByRenderingView
{
    UIGraphicsBeginImageContextWithOptions(self.bounds.size, NO, 0.0);
    [self drawViewHierarchyInRect:self.bounds afterScreenUpdates:YES];
    UIImage * snapshotImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return snapshotImage;
}

@end

old thread, but here's an updated possibility for ie8 and ff3.5 users:

function isHTMLElement(o) {
    return (o.constructor.toString().search(/\object HTML.+Element/) > -1);
}

I use it like this:

import jQuery from 'jQuery'

ready: function() {
    var self = this;
    jQuery(window).resize(function () {
      self.$refs.thisherechart.drawChart();
    })
  },

There is no default database for user. There is default database for current session.

You can get it using DATABASE() function -

SELECT DATABASE();

And you can set it using USE statement -

USE database1;

You should set it manually - USE db_name, or in the connection string.

You can't sort a Dictionary<TKey, TValue> - it's inherently unordered. (Or rather, the order in which entries are retrieved is implementation-specific. You shouldn't rely on it working the same way between versions, as ordering isn't part of its designed functionality.)

You can use SortedList<TKey, TValue> or SortedDictionary<TKey, TValue>, both of which sort by the key (in a configurable way, if you pass an IEqualityComparer<T> into the constructor) - might those be of use to you?

Pay little attention to the word "list" in the name SortedList - it's still a dictionary in that it maps keys to values. It's implemented using a list internally, effectively - so instead of looking up by hash code, it does a binary search. SortedDictionary is similarly based on binary searches, but via a tree instead of a list.

A last resort is sudo cp /usr/lib/python3/dist-packages/apt_pkg.cpython-35m-x86_64-linux-gnu.so /usr/lib/python3/dist-packages/apt_pkg.cpython-36m-x86_64-linux-gnu.so if the ln command is too much for you or somehow magically doesn't work.

cp above can also be mv if you are only dedicated to using one Python version.

 std::string some_str = SOME_VAL;
 if ( some_str.size() > 0 && some_str[some_str.length()-1] == '\n' ) 
  some_str.resize( some_str.length()-1 );

or (removes several newlines at the end)

some_str.resize( some_str.find_last_not_of(L"\n")+1 );

Breakpoints and especially conditional breakpoints are your friends.

Also you can write small assert like function which will check values and throw exceptions if needed in debug version of site (some variable is set to true or url has some parameter)

this could work for you.

using System.Linq;

DirectoryInfo info = new DirectoryInfo("PATH_TO_DIRECTORY_HERE");
FileInfo[] files = info.GetFiles().OrderBy(p => p.CreationTime).ToArray();
foreach (FileInfo file in files)
{
    // DO Something...
}

You have to use v-html directive for displaying html content inside a vue component

<div v-html="html content data property"></div>

@ModelAttribute is a Spring mapping of request parameters to a particular object type. so your parameters might look like userClient.username and userClient.firstName, etc. as MockMvc imitates a request from a browser, you'll need to pass in the parameters that Spring would use from a form to actually build the UserClient object.

(i think of ModelAttribute is kind of helper to construct an object from a bunch of fields that are going to come in from a form, but you may want to do some reading to get a better definition)

If you don't care about the ordering of the keys, you could do the following:

$array = YOUR_ARRAY
$unique = array();
foreach ($array as $a) {
    $unique[$a] = $a;
}

1. What exactly doesn't work?
2. Why are you using a 2d array?

3. If you must use a 2d array:

   int numOfPairs = 10;  String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){     for(int j = 0; j < array[i].length; j++){         array[i] = new String[2];         array[i][0] = "original word";         array[i][1] = "rearranged word";     }    } 

Does this give you a hint?

In most project types, your async "up" and "down" will end at an async void event handler or returning a Task to your framework.

However, Console apps do not support this.

You can either just do a Wait on the returned task:

static void Main()
{
  MainAsync().Wait();
  // or, if you want to avoid exceptions being wrapped into AggregateException:
  //  MainAsync().GetAwaiter().GetResult();
}

static async Task MainAsync()
{
  ...
}

or you can use your own context like the one I wrote:

static void Main()
{
  AsyncContext.Run(() => MainAsync());
}

static async Task MainAsync()
{
  ...
}

More information for async Console apps is on my blog.
