I Had similar issue. Every project has his own gradle folder, check if in your project root there's another gradle folder:

/my_projects_root_folder/project/gradle
/my_projects_root_folder/gradle

If so, in every folder you'll find /gradle/wrapper/gradle-wrapper.properties.

Check if in /my_projects_root_folder/gradle/gradle-wrapper.properties gradle version at least match /my_projects_root_folder/ project/ gradle/ gradle-wrapper.properties gradle version

Or just delete/rename your /my_projects_root_folder/gradle and restart android studio and let Gradle sync work and download required gradle.

This is actually pretty easy to fix and doesn't take any coding:

1.Click on the Plots tab above the console. 2.Then at the top right corner of the plots screen click on the options button. 3.Lastly uncheck the "Mute inline plotting" button

Now re-run your script and your graphs should show up in the console.

Cheers.

And if you prefer hosted solution, you should check out Open Hub (formerly Ohloh.net). It is nice, but don't expect large statistics.

Have you tried adding lines below to your web.xml?

<context-param>
   <param-name>com.sun.faces.enableRestoreView11Compatibility</param-name>
   <param-value>true</param-value>
</context-param>

I found this to be very effective when I encountered this issue.

Although I'm sure this won't be accepted as the answer to this very old question, I came here looking for a way to do this and this is how I solved the problem.

I created a demonstration here at codepen.io.

The Html:

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.13.0/moment.min.js" type="text/javascript"></script>
<script src="https://cdn.rawgit.com/mckamey/countdownjs/master/countdown.min.js" type="text/javascript"></script>
<script src="https://code.jquery.com/jquery-3.0.0.min.js" type="text/javascript"></script>
<div>
  The time is now: <span class="now"></span>, a timer will go off <span class="duration"></span> at <span class="then"></span>
</div>
<div class="difference">The timer is set to go off <span></span></div>
<div class="countdown"></div>

The Javascript:

var now = moment(); // new Date().getTime();
var then = moment().add(60, 'seconds'); // new Date(now + 60 * 1000);

$(".now").text(moment(now).format('h:mm:ss a'));
$(".then").text(moment(then).format('h:mm:ss a'));
$(".duration").text(moment(now).to(then));
(function timerLoop() {
  $(".difference > span").text(moment().to(then));
  $(".countdown").text(countdown(then).toString());
  requestAnimationFrame(timerLoop);
})();

Output:

The time is now: 5:29:35 pm, a timer will go off in a minute at 5:30:35 pm
The timer is set to go off in a minute
1 minute

Note: 2nd line above updates as per momentjs and 3rd line above updates as per countdownjs and all of this is animated at about ~60FPS because of requestAnimationFrame()

Code Snippet:

Alternatively you can just look at this code snippet:

var now = moment(); // new Date().getTime();_x000D_
var then = moment().add(60, 'seconds'); // new Date(now + 60 * 1000);_x000D_

Requirements:

• CountdownJS: http://countdownjs.org/ (And Rawgit to be able to use countdownjs)
• MomentJS: http://momentjs.com/
• requestAnimationFrame() - use this for animation rather than setInterval().

Optional Requirements:

• jQuery: https://jquery.com/

Additionally here is some light reading about the requestAnimationFrame() pattern:

• http://www.paulirish.com/2011/requestanimationframe-for-smart-animating/
• https://css-tricks.com/using-requestanimationframe/

I found the requestAnimationFrame() pattern to be much a more elegant solution than the setInterval() pattern.

Michael's suggestion of running your own nbviewer instance is a good one I used in the past with an Enterprise Github server.

Another lightweight alternative is to have a cell at the end of your notebook that does a shell call to nbconvert so that it's automatically refreshed after running the whole thing:

!ipython nbconvert <notebook name>.ipynb --to html

EDIT: With Jupyter/IPython's Big Split, you'll probably want to change this to !jupyter nbconvert <notebook name>.ipynb --to html now.

First, it usually does not matter that much in practice. Most hash functions are "good enough".

But if you really care, you should know that it is a research subject by itself. There are thousand of papers about that. You can still get a PhD today by studying & designing hashing algorithms.

Your second hash function might be slightly better, because it probably should separate the string "ab" from the string "ba". On the other hand, it is probably less quick than the first hash function. It may, or may not, be relevant for your application.

I'll guess that hash functions used for genome strings are quite different than those used to hash family names in telephone databases. Perhaps even some string hash functions are better suited for German, than for English or French words.

Many software libraries give you good enough hash functions, e.g. Qt has qhash, and C++11 has std::hash in <functional>, Glib has several hash functions in C, and POCO has some hash function.

I quite often have hashing functions involving primes (see Bézout's identity) and xor, like e.g.

#define A 54059 /* a prime */
#define B 76963 /* another prime */
#define C 86969 /* yet another prime */
#define FIRSTH 37 /* also prime */
unsigned hash_str(const char* s)
{
   unsigned h = FIRSTH;
   while (*s) {
     h = (h * A) ^ (s[0] * B);
     s++;
   }
   return h; // or return h % C;
}

But I don't claim to be an hash expert. Of course, the values of A, B, C, FIRSTH should preferably be primes, but you could have chosen other prime numbers.

Look at some MD5 implementation to get a feeling of what hash functions can be.

Most good books on algorithmics have at least a whole chapter dedicated to hashing. Start with wikipages on hash function & hash table.

Just to add my answer, it seems that the transitions need to be based on initial values and final values within the css properties to be able to manage the animation.

Those reworked css classes should provide the expected result :

.box{_x000D_
    position: relative;  _x000D_
    top:0px;_x000D_
    left:0px;_x000D_
    width:0px;_x000D_
}_x000D_
_x000D_
.box:hover .hidden{_x000D_
    opacity: 1;_x000D_
     width: 500px;_x000D_
}_x000D_
_x000D_
.box .hidden{    _x000D_
   background: yellow;_x000D_
    height: 300px;    _x000D_
    position: absolute; _x000D_
    top: 0px;_x000D_
    left: 0px;    _x000D_
    width: 0px;_x000D_
    opacity: 0;    _x000D_
    transition: all 1s ease;_x000D_
}

<div class="box">_x000D_
_x000D_
    <a href="#">_x000D_
        <img src="http://farm9.staticflickr.com/8207/8275533487_5ebe5826ee.jpg"></a>_x000D_
        <div class="hidden"></div>_x000D_
_x000D_
</div>

http://jsfiddle.net/u2FKM/2199/

All the three syntax work very well.

Another way is to first write

path = r'C:\user\...................' (whatever is the path for you)

and then passing it to os.chdir(path)

I would like to point out over here that Overloading in PHP has a completely different meaning as compared to other programming languages. A lot of people have said that overloading isnt supported in PHP and by the conventional definition of overloading, yes that functionality isnt explicitly available.

However, the correct definition of overloading in PHP is completely different.

In PHP overloading refers to dynamically creating properties and methods using magic methods like __set() and __get(). These overloading methods are invoked when interacting with methods or properties that are not accessible or not declared.

Here is a link from the PHP manual : http://www.php.net/manual/en/language.oop5.overloading.php

The cleanest solution I've found is as follows:

This example is to perform two very different actions; the basic premise is to use the value to pass data to the action.

In your view:

@using (Html.BeginForm("DliAction", "Dli", FormMethod.Post, new { id = "mainForm" }))
{
    if (isOnDli)
    {
        <button name="removeDli" value="@result.WeNo">Remove From DLI</button>
    }
    else
    {
        <button name="performDli" value="@result.WeNo">Perform DLI</button>
    }
}

Then in your action:

    public ActionResult DliAction(string removeDli, string performDli)
    {
        if (string.IsNullOrEmpty(performDli))
        {
            ...
        }
        else if (string.IsNullOrEmpty(removeDli))
        {
            ...
        }

        return View();
    }

This code should be easy to alter in order to achieve variations along the theme, e.g. change the button's name to be the same, then you only need one parameter on the action etc, as can be seen below:

In your view:

@using (Html.BeginForm("DliAction", "Dli", FormMethod.Post, new { id = "mainForm" }))
{

        <button name="weNo" value="@result.WeNo">Process This WeNo</button>

        <button name="weNo" value="@result.WeNo">Process A Different WeNo This Item</button>
}

Then in your action:

    public ActionResult DliAction(string weNo)
    {
        // Process the weNo...

        return View();
    }

If you want to change the url in address bar:

const search = new URLSearchParams(location.search);
search.set('rows', 10);
location.search = search.toString();

Note, changing location.search reloads the page.

jsonData = """{"from": {"id": "8", "name": "Mary Pinter"}, "message": "How ARE you?", "comments": {"count": 0}, "updated_time": "2012-05-01", "created_time": "2012-05-01", "to": {"data": [{"id": "1543", "name": "Honey Pinter"}, {"name": "Joe Schmoe"}]}, "type": "status", "id": "id_7"}"""

def getTargetIds(jsonData):
    data = json.loads(jsonData)
    for dest in data['to']['data']:
        print("to_id:", dest.get('id', 'null'))

Try it:

>>> getTargetIds(jsonData)
to_id: 1543
to_id: null

Or, if you just want to skip over values missing ids instead of printing 'null':

def getTargetIds(jsonData):
    data = json.loads(jsonData)
    for dest in data['to']['data']:
        if 'id' in to_id:
            print("to_id:", dest['id'])

So:

>>> getTargetIds(jsonData)
to_id: 1543

Of course in real life, you probably don't want to print each id, but to store them and do something with them, but that's another issue.

I think you can use date() function to achive this

$date = '19:24:15 06/13/2013'; 
echo date('h:i:s a m/d/Y', strtotime($date));

This will output

07:24:15 pm 06/13/2013

Live Sample

h is used for 12 digit time
i stands for minutes
s seconds
a will return am or pm (use in uppercase for AM PM)
m is used for months with digits
d is used for days in digit
Y uppercase is used for 4 digit year (use it lowercase for two digit)

Updated

This is with DateTime

$date = new DateTime('19:24:15 06/13/2013');
echo $date->format('h:i:s a m/d/Y') ;

Live Sample

CSS Cursor:Pointer; is a great solution. FastClick https://github.com/ftlabs/fastclick is another solution which doesn't require you to change css if you didn't want Cursor:Pointer; on an element for some reason. I use fastclick now anyway to eliminate the 300ms delay on iOS devices.

For some components, it is easier to use inline styles. Also, I find it easier and more concise (as I'm using Javascript and not CSS) to animate component styles.

For stand-alone components, I use the 'Spread Operator' or the '...'. For me, it's clear, beautiful, and works in a tight space. Here is a little loading animation I made to show it's benefits:

<div style={{...this.styles.container, ...this.state.opacity}}>
    <div style={{...this.state.colors[0], ...this.styles.block}}/>
    <div style={{...this.state.colors[1], ...this.styles.block}}/>
    <div style={{...this.state.colors[2], ...this.styles.block}}/>
    <div style={{...this.state.colors[7], ...this.styles.block}}/>
    <div style={{...this.styles.block}}/>
    <div style={{...this.state.colors[3], ...this.styles.block}}/>
    <div style={{...this.state.colors[6], ...this.styles.block}}/>
    <div style={{...this.state.colors[5], ...this.styles.block}}/>
    <div style={{...this.state.colors[4], ...this.styles.block}}/>
  </div>

    this.styles = {
  container: {
    'display': 'flex',
    'flexDirection': 'row',
    'justifyContent': 'center',
    'alignItems': 'center',
    'flexWrap': 'wrap',
    'width': 21,
    'height': 21,
    'borderRadius': '50%'
  },
  block: {
    'width': 7,
    'height': 7,
    'borderRadius': '50%',
  }
}
this.state = {
  colors: [
    { backgroundColor: 'red'},
    { backgroundColor: 'blue'},
    { backgroundColor: 'yellow'},
    { backgroundColor: 'green'},
    { backgroundColor: 'white'},
    { backgroundColor: 'white'},
    { backgroundColor: 'white'},
    { backgroundColor: 'white'},
    { backgroundColor: 'white'},
  ],
  opacity: {
    'opacity': 0
  }
}

EDIT NOVEMBER 2019

Working in the industry (A Fortune 500 company), I am NOT allowed to make any inline styling. In our team, we've decided that inline style are unreadable and not maintainable. And, after having seen first hand how inline styles make supporting an application completely intolerable, I'd have to agree. I completely discourage inline styles.

I found another solution here, since I ran into both post...

This is from the Myles answer:

<ListBox.ItemContainerStyle> 
    <Style TargetType="ListBoxItem"> 
        <Setter Property="HorizontalContentAlignment" Value="Stretch"></Setter> 
    </Style> 
</ListBox.ItemContainerStyle> 

This worked for me.

Try collect function in array like:

$comments_collection = collect($post->comments()->get()->toArray());

this methods can help you

toArray() with collect()

It seems strange, but nonetheless HTML5 supports drawing lines, circles, rectangles and many other basic shapes, it does not have anything suitable for drawing the basic point. The only way to do so is to simulate a point with whatever you have.

So basically there are 3 possible solutions:

• draw point as a line
• draw point as a polygon
• draw point as a circle

Each of them has their drawbacks.

Line

function point(x, y, canvas){
  canvas.beginPath();
  canvas.moveTo(x, y);
  canvas.lineTo(x+1, y+1);
  canvas.stroke();
}

Keep in mind that we are drawing to South-East direction, and if this is the edge, there can be a problem. But you can also draw in any other direction.

Rectangle

function point(x, y, canvas){
  canvas.strokeRect(x,y,1,1);
}

or in a faster way using fillRect because render engine will just fill one pixel.

function point(x, y, canvas){
  canvas.fillRect(x,y,1,1);
}

Circle

One of the problems with circles is that it is harder for an engine to render them

function point(x, y, canvas){
  canvas.beginPath();
  canvas.arc(x, y, 1, 0, 2 * Math.PI, true);
  canvas.stroke();
}

the same idea as with rectangle you can achieve with fill.

function point(x, y, canvas){
  canvas.beginPath();
  canvas.arc(x, y, 1, 0, 2 * Math.PI, true);
  canvas.fill();
}

Problems with all these solutions:

• it is hard to keep track of all the points you are going to draw.
• when you zoom in, it looks ugly

If you are wondering, what is the best way to draw a point, I would go with filled rectangle. You can see my jsperf here with comparison tests

you can round your double and cast ist:

(int)Math.Round(myDouble);

def capitalizeWords(s):
  return re.sub(r'\w+', lambda m:m.group(0).capitalize(), s)

re.sub can take a function for the "replacement" (rather than just a string, which is the usage most people seem to be familiar with). This repl function will be called with an re.Match object for each match of the pattern, and the result (which should be a string) will be used as a replacement for that match.

A longer version of the same thing:

WORD_RE = re.compile(r'\w+')

def capitalizeMatch(m):
  return m.group(0).capitalize()

def capitalizeWords(s):
  return WORD_RE.sub(capitalizeMatch, s)

This pre-compiles the pattern (generally considered good form) and uses a named function instead of a lambda.

How about writing your own concat method?

public static Stream<T> concat(Stream<? extends T> a, 
                               Stream<? extends T> b, 
                               Stream<? extends T> args)
{
    Stream<T> concatenated = Stream.concat(a, b);
    for (Stream<T> stream : args)
    {
        concatenated = Stream.concat(concatenated, stream);
    }
    return concatenated;
}

This at least makes your first example a lot more readable.

Just to expand on casperOne's answer.

The JSON spec does not account for Date values. MS had to make a call, and the path they chose was to exploit a little trick in the javascript representation of strings: the string literal "/" is the same as "\/", and a string literal will never get serialized to "\/" (even "\/" must be mapped to "\\/").

See http://msdn.microsoft.com/en-us/library/bb299886.aspx#intro_to_json_topic2 for a better explanation (scroll down to "From JavaScript Literals to JSON")

One of the sore points of JSON is the lack of a date/time literal. Many people are surprised and disappointed to learn this when they first encounter JSON. The simple explanation (consoling or not) for the absence of a date/time literal is that JavaScript never had one either: The support for date and time values in JavaScript is entirely provided through the Date object. Most applications using JSON as a data format, therefore, generally tend to use either a string or a number to express date and time values. If a string is used, you can generally expect it to be in the ISO 8601 format. If a number is used, instead, then the value is usually taken to mean the number of milliseconds in Universal Coordinated Time (UTC) since epoch, where epoch is defined as midnight January 1, 1970 (UTC). Again, this is a mere convention and not part of the JSON standard. If you are exchanging data with another application, you will need to check its documentation to see how it encodes date and time values within a JSON literal. For example, Microsoft's ASP.NET AJAX uses neither of the described conventions. Rather, it encodes .NET DateTime values as a JSON string, where the content of the string is /Date(ticks)/ and where ticks represents milliseconds since epoch (UTC). So November 29, 1989, 4:55:30 AM, in UTC is encoded as "\/Date(628318530718)\/".

A solution would be to just parse it out:

value = new Date(parseInt(value.replace("/Date(", "").replace(")/",""), 10));

However I've heard that there is a setting somewhere to get the serializer to output DateTime objects with the new Date(xxx) syntax. I'll try to dig that out.

The second parameter of JSON.parse() accepts a reviver function where prescribes how the value originally produced by, before being returned.

Here is an example for date:

var parsed = JSON.parse(data, function(key, value) {
  if (typeof value === 'string') {
    var d = /\/Date\((\d*)\)\//.exec(value);
    return (d) ? new Date(+d[1]) : value;
  }
  return value;
});

See the docs of JSON.parse()

:.,$d

This will delete all content from current line to end of the file. This is very useful when you're dealing with test vector generation or stripping.

To detect WIFI connection state, I have used CONNECTIVITY_ACTION from ConnectivityManager class so:

    IntentFilter filter=new IntentFilter();
    filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
    registerReceiver(receiver, filter);

and from your BroadCastReceiver:

    if (ConnectivityManager.CONNECTIVITY_ACTION.equals(action)) {
        int networkType = intent.getIntExtra(
                android.net.ConnectivityManager.EXTRA_NETWORK_TYPE, -1);
        if (ConnectivityManager.TYPE_WIFI == networkType) {
            NetworkInfo networkInfo = (NetworkInfo) intent
                    .getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO);
            if (networkInfo != null) {
                if (networkInfo.isConnected()) {

                    // TODO: wifi is connected
                } else {
                    // TODO: wifi is not connected
                }
            }
        }

    }

ps:works fine for me:)

This package seems to be a good solution for the underlying issue of having non-unique IDs in your DOM across multiple components:

vue-uniq-ids

It is a trend to use components. Components are cool, they are small, obvious, easy to use and modular. Untill it comes to the id property.

Some HTML tag attributes requires using an id property, like label[for], input[form] and many of aria-* attributes. And the problem with the id is that it is not modular. If several id properties on the page will has the same value they can affect each other.

VueUniqIds helps you to get rid of this problem. It provides the set of id-related directives which value is automatically modified by adding unique string while keeping the attrbitue easy to read.

1. go to regedit ( go to search and type regedit)
2. expand "HKEY_CURRENT_USER" node
3. under HKEY_CURRENT_USER node expand "software" node
4. under software node expand "microsoft" node
5. under microsoft node click on "Command Processor"
6. path looks like this : "HKEY_CURRENT_USER\Software\Microsoft\Command Processor"

it looks something like this :

7. if you do not see "Autorun" String Value
8. Right Click - New - Expandable String Value, and rename it to Autorun
9. double click on "Autorun" 10.enter this value path format:
10. "CD/d C:\yourfoldername\yoursubfoldername"

This is my final code .... (based on previous fixes, thank you big time for headstart, saved a lot of time experimenting). What bugged me was scrolling up, as well as scrolling down ... :)

it always makes me wonder how jquery can be elegant!!!

$(document).ready(function(){

    //run once
    var el=$('#scrolldiv');
    var originalelpos=el.offset().top; // take it where it originally is on the page

    //run on scroll
     $(window).scroll(function(){
        var el = $('#scrolldiv'); // important! (local)
        var elpos = el.offset().top; // take current situation
        var windowpos = $(window).scrollTop();
        var finaldestination = windowpos+originalelpos;
        el.stop().animate({'top':finaldestination},500);
     });

});

A solution using recursion:

def brute(string, length, charset):
    if len(string) == length:
        return
    for char in charset:
        temp = string + char
        print(temp)
        brute(temp, length, charset)

Usage:

brute("", 4, "rce")

We can use four methods for this conversion

1. parseInt with radix 10
2. Number Constructor
3. Unary Plus Operator
4. Using mathematical functions (subtraction)

const numString = "065";_x000D_
_x000D_
//parseInt with radix=10_x000D_
let number = parseInt(numString, 10);_x000D_
console.log(number);_x000D_
_x000D_
// Number constructor_x000D_
number = Number(numString);_x000D_
console.log(number);_x000D_
_x000D_
// unary plus operator_x000D_
number = +numString;_x000D_
console.log(number);_x000D_
_x000D_
// conversion using mathematical function (subtraction)_x000D_
number = numString - 0;_x000D_
console.log(number);

Update(based on comments): Why doesn't this work on "large numbers"?

For the primitive type Number, the safest max value is 2^53-1(Number.MAX_SAFE_INTEGER).

console.log(Number.MAX_SAFE_INTEGER);

Now, lets consider the number string '099999999999999999999' and try to convert it using the above methods

const numString = '099999999999999999999';_x000D_
_x000D_
let parsedNumber = parseInt(numString, 10);_x000D_
console.log(`parseInt(radix=10) result: ${parsedNumber}`);_x000D_
_x000D_
parsedNumber = Number(numString);_x000D_
console.log(`Number conversion result: ${parsedNumber}`);_x000D_
_x000D_
parsedNumber = +numString;_x000D_
console.log(`Appending Unary plus operator result: ${parsedNumber}`);_x000D_
_x000D_
parsedNumber = numString - 0;_x000D_
console.log(`Subtracting zero conversion result: ${parsedNumber}`);

All results will be incorrect.

That's because, when converted, the numString value is greater than Number.MAX_SAFE_INTEGER. i.e.,

99999999999999999999 > 9007199254740991

This means all operation performed with the assumption that the stringcan be converted to number type fails.

For numbers greater than 2⁵³, primitive BigInt has been added recently. Check browser compatibility of BigInthere.

The conversion code will be like this.

const numString = '099999999999999999999';
const number = BigInt(numString);

P.S: Why radix is important for parseInt?

If radix is undefined or 0 (or absent), JavaScript assumes the following:

• If the input string begins with "0x" or "0X", radix is 16 (hexadecimal) and the remainder of the string is parsed
• If the input string begins with "0", radix is eight (octal) or 10 (decimal)
• If the input string begins with any other value, the radix is 10 (decimal)

Exactly which radix is chosen is implementation-dependent. ECMAScript 5 specifies that 10 (decimal) is used, but not all browsers support this yet.

For this reason, always specify a radix when using parseInt

Below answer worked for angular 4/5.

In app.component.css

.image{
     height:40em; background-size:cover; width:auto;
     background-image:url('copied image address');
     background-position:50% 50%;
   }

Also in app.component.html simply add as below

<div class="image">
Your content
</div>

This way I was able to set background image in Angular 4/5.

When using angular-cli, this is what works for me:

can you Try this and tell me what happens ?? :

JAVA :

ImageView imgFavorite = (ImageView) findViewById(R.id.favorite_icon);
imgFavorite.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Toast.makeText(YourActivityName.this,
                "The favorite list would appear on clicking this icon",
                Toast.LENGTH_LONG).show();
    }
});

or you should add this :

imgFavorite.setClickable(true); 

KOTLIN :

imgFavorite.setOnClickListener { view ->
    Toast.makeText(this@YourActivityName, R.string.toast_favorite_list_would_appear, Toast.LENGTH_LONG).show()
}
// either you make your imageView clickable programmatically
imgFavorite.clickable = true

// or via xml on your layout file
<ImageView .... android:clickable="true" />

Here is example of getting substring from 14 character to end of string. You can modify it to fit your needs

string text = "Retrieves a substring from this instance. The substring starts at a specified character position.";
//get substring where 14 is start index
string substring = text.Substring(14);

If you are using Angular CLI: 7.3.3 What I did is, On my assets folder I put my fake json data then on my services I just did this.

const API_URL = './assets/data/db.json';

getAllPassengers(): Observable<PassengersInt[]> {
    return this.http.get<PassengersInt[]>(API_URL);
  }

Bootstrap has a way of using media queries to define the different task for different sites. It uses four breakpoints.

we have extra small screen sizes which are less than 576 pixels that small in which I mean it's size from 576 to 768 pixels.

medium screen sizes take up screen size from 768 pixels up to 992 pixels large screen size from 992 pixels up to 1200 pixels.

E.g Small Text

This means that at the small screen between 576px and 768px, center the text For medium screen, change "sm" to "md" and same goes to large "lg"

As the documentation states, 'replace' determines whether the current element is replaced by the directive. The other option is whether it is just added to as a child basically. If you look at the source of your plnkr, notice that for the second directive where replace is false that the div tag is still there. For the first directive it is not.

First result:

<span myd1="">directive template1</span>

Second result:

<div myd2=""><span>directive template2</span></div>

Follow these steps to run your application on the device connected. 1. Change directories to the root of your Android project and execute: ant debug 2. Make sure the Android SDK platform-tools/ directory is included in your PATH environment variable, then execute: adb install bin/<*your app name*>-debug.apk On your device, locate <*your app name*> and open it.

Refer Running App

You can also use this lightweight npm package called absorb

It is 27 lines of code, 1kb and uses recursion to perform deep object merges.

var absorb = require('absorb');
var obj1, obj2;

obj1 = { foo: 123, bar: 456 };
obj2 = { bar: 123, key: 'value' }

absorb(obj1, obj2);

console.log(obj1); // Output: { foo: 123, bar: 123, key: 'value' }

You can also use it to make a clone or only transfer values if they don't exist in the source object, how to do this is detailed in the link provided.

It's a little difficult to tell what you're trying to achieve, but assuming you're trying to get a Base64 string that when decoded is abcdef==, the following should work:

byte[] bytes = Encoding.UTF8.GetBytes("abcdef==");
string base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);

This will output: YWJjZGVmPT0= which is abcdef== encoded in Base64.

Edit:

To decode a Base64 string, simply use Convert.FromBase64String(). E.g.

string base64 = "YWJjZGVmPT0=";
byte[] bytes = Convert.FromBase64String(base64);

At this point, bytes will be a byte[] (not a string). If we know that the byte array represents a string in UTF8, then it can be converted back to the string form using:

string str = Encoding.UTF8.GetString(bytes);
Console.WriteLine(str);

This will output the original input string, abcdef== in this case.

I had to use strcpy_s and it worked.

#include "stdafx.h"
#include<iostream>
#include<string>

using namespace std;

struct student
{
    char name[30];
    int age;
};

int main()
{

    struct student s1;
    char myname[30] = "John";
    strcpy_s (s1.name, strlen(myname) + 1 ,myname );
    s1.age = 21;

    cout << " Name: " << s1.name << " age: " << s1.age << endl;
    return 0;
}

If you are using a modern browser there's a simple solution.

First, attach a template variable to the input.

<input type="date" #date />

Then pass the variable into your receiving method.

<button (click)="submit(date)"></button>

In your controller just accept the parameter as type HTMLInputElement and use the method valueAsDate on the HTMLInputElement.

submit(date: HTMLInputElement){
    console.log(date.valueAsDate);
}

You can then manipulate the date anyway you would a normal date.

You can also set the value of your <input [value]= "..."> as you would normally.

Personally, as someone trying to stay true to the unidirectional data flow, i try to stay away from two way data binding in my components.

To expand a bit on Hossein Narimani Rad's answer, you can rename both a table and columns using System.ComponentModel.DataAnnotations.Schema.TableAttribute and System.ComponentModel.DataAnnotations.Schema.ColumnAttribute respectively.

This has a couple benefits:

1. Not only will this create the the name migrations automatically, but
2. it will also deliciously delete any foreign keys and recreate them against the new table and column names, giving the foreign keys and constaints proper names.
3. All this without losing any table data

For example, adding [Table("Staffs")]:

[Table("Staffs")]
public class AccountUser
{
    public long Id { get; set; }

    public long AccountId { get; set; }

    public string ApplicationUserId { get; set; }

    public virtual Account Account { get; set; }

    public virtual ApplicationUser User { get; set; }
}

Will generate the migration:

    protected override void Up(MigrationBuilder migrationBuilder)
    {
        migrationBuilder.DropForeignKey(
            name: "FK_AccountUsers_Accounts_AccountId",

        migrationBuilder.RenameIndex(
            name: "IX_Staffs_AccountId",

On Windows, open the Command Prompt program. You can do this by going to the Start menu

  keytool -exportcert -list -v -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

On Mac/Linux, open the Terminal and paste

   keytool -exportcert -list -v -alias androiddebugkey -keystore ~/.android/debug.keystore

I tried neemzy's approach, but it didn't work for me using 1.2.0-rc.3. The script tag would be inserted into the DOM, but the javascript path would not be loaded. I suspect it was because the javascript i was trying to load was from a different domain/protocol. So I took a different approach, and this is what I came up with, using google maps as an example: (Gist)

angular.module('testApp', []).
    directive('lazyLoad', ['$window', '$q', function ($window, $q) {
        function load_script() {
            var s = document.createElement('script'); // use global document since Angular's $document is weak
            s.src = 'https://maps.googleapis.com/maps/api/js?sensor=false&callback=initialize';
            document.body.appendChild(s);
        }
        function lazyLoadApi(key) {
            var deferred = $q.defer();
            $window.initialize = function () {
                deferred.resolve();
            };
            // thanks to Emil Stenström: http://friendlybit.com/js/lazy-loading-asyncronous-javascript/
            if ($window.attachEvent) {  
                $window.attachEvent('onload', load_script); 
            } else {
                $window.addEventListener('load', load_script, false);
            }
            return deferred.promise;
        }
        return {
            restrict: 'E',
            link: function (scope, element, attrs) { // function content is optional
            // in this example, it shows how and when the promises are resolved
                if ($window.google && $window.google.maps) {
                    console.log('gmaps already loaded');
                } else {
                    lazyLoadApi().then(function () {
                        console.log('promise resolved');
                        if ($window.google && $window.google.maps) {
                            console.log('gmaps loaded');
                        } else {
                            console.log('gmaps not loaded');
                        }
                    }, function () {
                        console.log('promise rejected');
                    });
                }
            }
        };
    }]);

I hope it's helpful for someone.

Assuming you want to change the colour of the currently selected link/tab... you're best bet is to apply a class (say active) to the currently selected link/tab and then style this differently.

Example style could be:

li.active, a.active {
  background-color: #f90;
}

I would like to add a design pattern that has been applied in Android Framework. This is Half Sync Half Async pattern used in the Asynctask implementation. See my discussion at

https://docs.google.com/document/d/1_zihWXAwgTAdJc013-bOLUHPMrjeUBZnDuPkzMxEEj0/edit?usp=sharing

but on the other hand it creates a completely useless list of integers just to loop over them. Isn't it a waste of memory, especially as far as big numbers of iterations are concerned?

That is what xrange(n) is for. It avoids creating a list of numbers, and instead just provides an iterator object.

In Python 3, xrange() was renamed to range() - if you want a list, you have to specifically request it via list(range(n)).

I build this solution, reformulate does not take care if variable names have white spaces.

add_backticks = function(x) {
    paste0("`", x, "`")
}

x_lm_formula = function(x) {
    paste(add_backticks(x), collapse = " + ")
}

build_lm_formula = function(x, y){
    if (length(y)>1){
        stop("y needs to be just one variable")
    }
    as.formula(        
        paste0("`",y,"`", " ~ ", x_lm_formula(x))
    )
}

# Example
df <- data.frame(
    y = c(1,4,6), 
    x1 = c(4,-1,3), 
    x2 = c(3,9,8), 
    x3 = c(4,-4,-2)
    )

# Model Specification
columns = colnames(df)
y_cols = columns[1]
x_cols = columns[2:length(columns)]
formula = build_lm_formula(x_cols, y_cols)
formula
# output
# "`y` ~ `x1` + `x2` + `x3`"

# Run Model
lm(formula = formula, data = df)
# output
Call:
    lm(formula = formula, data = df)

Coefficients:
    (Intercept)           x1           x2           x3  
        -5.6316       0.7895       1.1579           NA

If you simply call interrupt(), the thread will not automatically be closed. Instead, the Thread might even continue living, if isInterrupted() is implemented accordingly. The only way to guaranteedly close a thread, as asked for by OP, is

Thread.currentThread().stop();

Method is deprecated, however.

Calling return only returns from the current method. This only terminates the thread if you're at its top level.

Nevertheless, you should work with interrupt() and build your code around it.

I'll try and break it down (example from documention)

/* 
 *   The cellForRowAtIndexPath takes for argument the tableView (so if the same object
 *   is delegate for several tableViews it can identify which one is asking for a cell),
 *   and an indexPath which determines which row and section the cell is returned for. 
 */ 
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    /*
     *   This is an important bit, it asks the table view if it has any available cells
     *   already created which it is not using (if they are offScreen), so that it can
     *   reuse them (saving the time of alloc/init/load from xib a new cell ).
     *   The identifier is there to differentiate between different types of cells
     *   (you can display different types of cells in the same table view)
     */

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MyIdentifier"];

    /*
     *   If the cell is nil it means no cell was available for reuse and that we should
     *   create a new one.
     */
    if (cell == nil) {

        /* 
         *   Actually create a new cell (with an identifier so that it can be dequeued). 
         */

        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"MyIdentifier"] autorelease];

        cell.selectionStyle = UITableViewCellSelectionStyleNone;

    }

    /*
     *   Now that we have a cell we can configure it to display the data corresponding to
     *   this row/section
     */

    NSDictionary *item = (NSDictionary *)[self.content objectAtIndex:indexPath.row];
    cell.textLabel.text = [item objectForKey:@"mainTitleKey"];
    cell.detailTextLabel.text = [item objectForKey:@"secondaryTitleKey"];
    NSString *path = [[NSBundle mainBundle] pathForResource:[item objectForKey:@"imageKey"] ofType:@"png"];
    UIImage *theImage = [UIImage imageWithContentsOfFile:path];
    cell.imageView.image = theImage;

    /* Now that the cell is configured we return it to the table view so that it can display it */

    return cell;

}

This is a DataSource method so it will be called on whichever object has declared itself as the DataSource of the UITableView. It is called when the table view actually needs to display the cell onscreen, based on the number of rows and sections (which you specify in other DataSource methods).

Recently we had a similar problem and had to solve it in a different way. We had to merge two branches up to two commits, which were not the heads of either branches:

branch A: A1 -> A2 -> A3 -> A4
branch B: B1 -> B2 -> B3 -> B4
branch C: C1 -> A2 -> B3 -> C2

For example, we had to merge branch A up to A2 and branch B up to B3. But branch C had cherry-picks from A and B. When using the SHA of A2 and B3 it looked like there was confusion because of the local branch C which had the same SHA.

To avoid any kind of ambiguity we removed branch C locally, and then created a branch AA starting from commit A2:

git co A
git co SHA-of-A2
git co -b AA

Then we created a branch BB from commit B3:

git co B
git co SHA-of-B3
git co -b BB

At that point we merged the two branches AA and BB. By removing branch C and then referencing the branches instead of the commits it worked.

It's not clear to me how much of this was superstition or what actually made it work, but this "long approach" may be helpful.

Here is a basic explanation for TortoiseGit users:

git reset --soft and --mixed leave your files untouched.

git reset --hard actually change your files to match the commit you reset to.

In TortoiseGit, The concept of the index is very hidden by the GUI. When you modify a file, you don't have to run git add to add the change to the staging area/index. When simply dealing with modifications to existing files that are not changing file names, git reset --soft and --mixed are the same! You will only notice a difference if you added new files or renamed files. In this case, if you run git reset --mixed, you will have to re-add your file(s) from the Not Versioned Files list.

RETURNING

Since PostgreSQL 8.2, that's possible with a single round-trip to the database:

INSERT INTO tbl(filename)
VALUES ('my_filename')
RETURNING tbl_id;

tbl_id would typically be a serial or IDENTITY (Postgres 10 or later) column. More in the manual.

Explicitly fetch value

If filename needs to include tbl_id (redundantly), you can still use a single query.

Use lastval() or the more specific currval():

INSERT INTO tbl (filename)
VALUES ('my_filename' || currval('tbl_tbl_id_seq')   -- or lastval()
RETURNING tbl_id;

See:

• Reference value of serial column in another column during same INSERT

If multiple sequences may be advanced in the process (even by way of triggers or other side effects) the sure way is to use currval('tbl_tbl_id_seq').

Name of sequence

The string literal 'tbl_tbl_id_seq' in my example is supposed to be the actual name of the sequence and is cast to regclass, which raises an exception if no sequence of that name can be found in the current search_path.

tbl_tbl_id_seq is the automatically generated default for a table tbl with a serial column tbl_id. But there are no guarantees. A column default can fetch values from any sequence if so defined. And if the default name is taken when creating the table, Postgres picks the next free name according to a simple algorithm.

If you don't know the name of the sequence for a serial column, use the dedicated function pg_get_serial_sequence(). Can be done on the fly:

INSERT INTO tbl (filename)
VALUES ('my_filename' || currval(pg_get_serial_sequence('tbl', 'tbl_id'))
RETURNING tbl_id;

This is the workflow that I use at my job with the team. The scenario is as you described. First, when I'm done working on test I rebase with master to pull in whatever has been added to master during the time I've been working on the test branch.

git pull -r upstream master

This will pull the changes to master since you forked the test branch and apply them, and then apply the changes you've made to test "on top of" the current state of master. There may be conflicts here, if the other people have made changes to the same files that you've edited in test. If there are, you will have to fix them manually, and commit. Once you've done that, you'll be good to switch to the master branch and merge test in with no problems.

I still had a dark grey line after attempting the other answers. I had to add the following two lines to make everything "invisible" in terms of row lines between cells.

self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
self.tableView.separatorColor = [UIColor clearColor];

A very easy and logical way to Unique a multi dimension array is as follows,

If you have array like this:

Array
(
    [Key1] => Array
        (
            [0] => Value1
            [1] => Value2
            [2] => Value1
            [3] => Value3
            [4] => Value1
        )
    [Key2] => Array
        (
            [0] => Value1
            [1] => Value2
            [2] => Value1
            [3] => Value3
            [4] => Value4
        )
)

use foreach to solve this:

foreach($array as $k=>$v){
    $unique=array_unique($v);
    $array[$k]=$unique;
}

it will give you following result:

Array
(
    [Key1] => Array
        (
            [0] => Value1
            [1] => Value2
            [3] => Value3
        )
    [Key2] => Array
        (
            [0] => Value1
            [1] => Value2
            [3] => Value3
            [4] => Value4
        )
)

and if you want to rearrange the order of the keys,

foreach($array as $k=>$v){
    $unique= array_values(array_unique($v));
    $array[$k]=$unique;
}

This operation will give you arranged key values like this:

Array
(
    [Key1] => Array
        (
            [0] => Value1
            [1] => Value2
            [2] => Value3
        )
    [Key2] => Array
        (
            [0] => Value1
            [1] => Value2
            [2] => Value3
            [3] => Value4
        )
)

I hope this will clear everything.

In a single line it would be:

(new Form2()).Show();

Hope it helps.

[^,]*$

might do. (Matches everything after the last comma).

Explanation: [^,] matches every character except for ,. The * denotes that the regexp matches any number of repetition of [^,]. The $ sign matches the end of the line.

SQL Server doesn't allow you to reference the alias in the GROUP BY clause because of the logical order of processing. The GROUP BY clause is processed before the SELECT clause, so the alias is not known when the GROUP BY clause is evaluated. This also explains why you can use the alias in the ORDER BY clause.

Here is one source for information on the SQL Server logical processing phases.

If you are going to use it with Retrofit library, I suggest you to use Square's gson library as:

implementation 'com.squareup.retrofit2:converter-gson:2.4.0'

For information this comes under Item 48 - Avoid float and double when exact values are required, of Effective Java 2nd edition by Joshua Bloch. This book is jam packed with good stuff and definitely worth a look.

You need to specify the domain:

 $('.button1').click(function() {
   window.location = 'www.example.com/index.php?id=' + this.id;
 });

In my case, I was using an invalid string prefix.

Wrong:

path = f"D:\Folder\file.txt"

Right:

path = r"D:\Folder\file.txt"

Finding the linked examples somewhat confusing, I worked out some code that demonstrates a working array insert into a test table (jkl_test). Here's the table:

create table jkl_test (id number(9));

Here is .Net code for a simple Console application that connects to Oracle using ODP.Net and inserts an array of 5 integers:

using Oracle.DataAccess.Client;

namespace OracleArrayInsertExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // Open a connection using ODP.Net
            var connection = new OracleConnection("Data Source=YourDatabase; Password=YourPassword; User Id=YourUser");
            connection.Open();

            // Create an insert command
            var command = connection.CreateCommand();
            command.CommandText = "insert into jkl_test values (:ids)";

            // Set up the parameter and provide values
            var param = new OracleParameter("ids", OracleDbType.Int32);
            param.Value = new int[] { 22, 55, 7, 33, 11 };

            // This is critical to the process; in order for the command to 
            // recognize and bind arrays, an array bind count must be specified.
            // Set it to the length of the array.
            command.ArrayBindCount = 5;
            command.Parameters.Add(param);
            command.ExecuteNonQuery();
        }
    }
}

@ModelAttribute refers to a property of the Model object (the M in MVC ;) so let's say we have a form with a form backing object that is called "Person" Then you can have Spring MVC supply this object to a Controller method by using the @ModelAttribute annotation:

public String processForm(@ModelAttribute("person") Person person){
    person.getStuff();
}

On the other hand the annotation is used to define objects which should be part of a Model. So if you want to have a Person object referenced in the Model you can use the following method:

@ModelAttribute("person")
public Person getPerson(){
    return new Person();
}

This annotated method will allow access to the Person object in your View, since it gets automatically added to the Models by Spring.

See "Using @ModelAttribute".

I started down this path because ESXi's wget is not compiled with SSL and I wanted to download an OVA from a vendor's website directly onto the ESXi host which is on the other side of the world.

I had to disable the firewall(lazy)/enable https out by editing the rules(proper)

created the python script:

import ssl
import shutil
import tempfile
import urllib.request
context = ssl._create_unverified_context()

dlurl='https://somesite/path/whatever'
with urllib.request.urlopen(durl, context=context) as response:
    with open("file.ova", 'wb') as tmp_file:
        shutil.copyfileobj(response, tmp_file)

ESXi libraries are kind of paired down but the open source weasel installer seemed to use urllib for https... so it inspired me to go down this path

Both your examples are equivalent. However, the first one is less obvious and more "hacky", while the second one clearly states your intention.

int (*pointer)[280];
pointer = tab1;

pointer points to an 1D array of 280 integers. In your assignment, you actually assign the first row of tab1. This works since you can implicitly cast arrays to pointers (to the first element).

When you are using pointer[5][12], C treats pointer as an array of arrays (pointer[5] is of type int[280]), so there is another implicit cast here (at least semantically).

In your second example, you explicitly create a pointer to a 2D array:

int (*pointer)[100][280];
pointer = &tab1;

The semantics are clearer here: *pointer is a 2D array, so you need to access it using (*pointer)[i][j].

Both solutions use the same amount of memory (1 pointer) and will most likely run equally fast. Under the hood, both pointers will even point to the same memory location (the first element of the tab1 array), and it is possible that your compiler will even generate the same code.

The first solution is "more advanced" since one needs quite a deep understanding on how arrays and pointers work in C to understand what is going on. The second one is more explicit.

Your setMaxResults($limit) needs to be set on the object.

e.g.

$query_ids = $this->getEntityManager()
  ->createQuery(
    "SELECT e_.id
    FROM MuzichCoreBundle:Element e_
    WHERE [...]
    GROUP BY e_.id")
;
$query_ids->setMaxResults($limit);

You need to order them.

SELECT * FROM messages GROUP BY from_id ORDER BY timestamp DESC LIMIT 1

For anyone using knockout.js, I wanted some knockout.js observable properties that would tell me when the breakpoints are hit. I opted to use Modernizr's support for css-style media queries so the numbers matched the bootstrap definitions, and to get modernizr's compatibility benefits. My knockout view model is as follows:

var viewModel = function() {
    // depends on jquery, Modernizr
    var self = this;
    self.widthXsOrLess = ko.observable();
    self.widthSmOrLess = ko.observable();
    self.widthMdOrLess = ko.observable();
    var setWindowSizeVars = function() {
        self.widthXsOrLess(!Modernizr.mq('(min-width: 768px)'));
        self.widthSmOrLess(!Modernizr.mq('(min-width: 992px)'));
        self.widthMdOrLess(!Modernizr.mq('(min-width: 1200px)'));
    };
    $(window).resize(setWindowSizeVars);
    setWindowSizeVars();
};

All objects in Java are references and you can use them like pointers.

abstract class Animal
{...
}

class Lion extends Animal
{...
}

class Tiger extends Animal
{   
public Tiger() {...}
public void growl(){...}
}

Tiger first = null;
Tiger second = new Tiger();
Tiger third;

Dereferencing a null:

first.growl();  // ERROR, first is null.    
third.growl(); // ERROR, third has not been initialized.

Aliasing Problem:

third = new Tiger();
first = third;

Losing Cells:

second = third; // Possible ERROR. The old value of second is lost.    

You can make this safe by first assuring that there is no further need of the old value of second or assigning another pointer the value of second.

first = second;
second = third; //OK

Note that giving second a value in other ways (NULL, new...) is just as much a potential error and may result in losing the object that it points to.

The Java system will throw an exception (OutOfMemoryError) when you call new and the allocator cannot allocate the requested cell. This is very rare and usually results from run-away recursion.

Note that, from a language point of view, abandoning objects to the garbage collector are not errors at all. It is just something that the programmer needs to be aware of. The same variable can point to different objects at different times and old values will be reclaimed when no pointer references them. But if the logic of the program requires maintaining at least one reference to the object, It will cause an error.

Novices often make the following error.

Tiger tony = new Tiger();
tony = third; // Error, the new object allocated above is reclaimed. 

What you probably meant to say was:

Tiger tony = null;
tony = third; // OK.

Improper Casting:

Lion leo = new Lion();
Tiger tony = (Tiger)leo; // Always illegal and caught by compiler. 

Animal whatever = new Lion(); // Legal.
Tiger tony = (Tiger)whatever; // Illegal, just as in previous example.
Lion leo = (Lion)whatever; // Legal, object whatever really is a Lion.

Pointers in C:

void main() {   
    int*    x;  // Allocate the pointers x and y
    int*    y;  // (but not the pointees)

    x = malloc(sizeof(int));    // Allocate an int pointee,
                                // and set x to point to it

    *x = 42;    // Dereference x to store 42 in its pointee

    *y = 13;    // CRASH -- y does not have a pointee yet

    y = x;      // Pointer assignment sets y to point to x's pointee

    *y = 13;    // Dereference y to store 13 in its (shared) pointee
}

Pointers in Java:

class IntObj {
    public int value;
}

public class Binky() {
    public static void main(String[] args) {
        IntObj  x;  // Allocate the pointers x and y
        IntObj  y;  // (but not the IntObj pointees)

        x = new IntObj();   // Allocate an IntObj pointee
                            // and set x to point to it

        x.value = 42;   // Dereference x to store 42 in its pointee

        y.value = 13;   // CRASH -- y does not have a pointee yet

        y = x;  // Pointer assignment sets y to point to x's pointee

        y.value = 13;   // Deference y to store 13 in its (shared) pointee
    }
} 

UPDATE: as suggested in the comments one must note that C has pointer arithmetic. However, we do not have that in Java.

Synchronous one-liner:

require('child_process').execSync("echo 'hi'", function puts(error, stdout, stderr) { console.log(stdout) });

base64.b16encode and base64.b16decode convert bytes to and from hex and work across all Python versions. The codecs approach also works, but is less straightforward in Python 3.

== operator compares the reference of an object in Java. You can use string's equals method .

String s = "Test";
if(s.equals("Test"))
{
    System.out.println("Equal");
}

This method will create the folder if it does not exist and do nothing if it exists:

Directory.CreateDirectory(path);

myLabel.setHorizontalAlignment(SwingConstants.CENTER);
myLabel.setVerticalAlignment(SwingConstants.CENTER);

If you cannot reconstruct the label for some reason, this is how you edit these properties of a pre-existent JLabel.

Yes, package-lock.json is intended to be checked into source control. If you're using npm 5+, you may see this notice on the command line: created a lockfile as package-lock.json. You should commit this file. According to npm help package-lock.json:

package-lock.json is automatically generated for any operations where npm modifies either the node_modules tree, or package.json. It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.

This file is intended to be committed into source repositories, and serves various purposes:

• Describe a single representation of a dependency tree such that teammates, deployments, and continuous integration are guaranteed to install exactly the same dependencies.

• Provide a facility for users to "time-travel" to previous states of node_modules without having to commit the directory itself.

• To facilitate greater visibility of tree changes through readable source control diffs.

• And optimize the installation process by allowing npm to skip repeated metadata resolutions for previously-installed packages.

One key detail about package-lock.json is that it cannot be published, and it will be ignored if found in any place other than the toplevel package. It shares a format with npm-shrinkwrap.json, which is essentially the same file, but allows publication. This is not recommended unless deploying a CLI tool or otherwise using the publication process for producing production packages.

If both package-lock.json and npm-shrinkwrap.json are present in the root of a package, package-lock.json will be completely ignored.

Well if you are doing this in Asp.Net or have access to HttpContext.Current.Request I'd say these are easier and more general ways of getting them:

var scheme = Request.Url.Scheme; // will get http, https, etc.
var host = Request.Url.Host; // will get www.mywebsite.com
var port = Request.Url.Port; // will get the port
var path = Request.Url.AbsolutePath; // should get the /pages/page1.aspx part, can't remember if it only get pages/page1.aspx

I hope this helps. :)

Drivers

chrome = 57.0.2987.133
chromedriver = 2.27.440174

Code:

from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_argument("--window-size=1920,1080")
driver = Chrome(chrome_options=chrome_options)

Note the plural in this method:

document.getElementsByName()

That returns an array of elements, so use [0] to get the first occurence, e.g.

document.getElementsByName()[0]

Since I want my project to compile to a stand-alone EXE file, I linked the UnitTest project to the function.obj file generated from function.cpp and it works.

Right click on the 'UnitTest1' project ? Configuration Properties ? Linker ? Input ? Additional Dependencies ? add "..\MyProjectTest\Debug\function.obj".

If you throw the exception, the method execution will stop and the exception is thrown to the caller method. throw always interrupt the execution flow of the current method. a try/catch block is something you could write when you call a method that may throw an exception, but throwing an exception just means that method execution is terminated due to an abnormal condition, and the exception notifies the caller method of that condition.

Find this tutorial about exception and how they work - http://docs.oracle.com/javase/tutorial/essential/exceptions/

My experience in Visual Studio 2010 is that there are two changes needed so as to not need DLL's. From the project property page (right click on the project name in the Solution Explorer window):

1. Under Configuration Properties --> General, change the "Use of MFC" field to "Use MFC in a Static Library".

2. Under Configuration Properties --> C/C++ --> Code Generation, change the "Runtime Library" field to "Multi-Threaded (/MT)"

Not sure why both were needed. I used this to remove a dependency on glut32.dll.

Added later: When making these changes to the configurations, you should make them to "All Configurations" --- you can select this at the top of the Properties window. If you make the change to just the Debug configuration, it won't apply to the Release configuration, and vice-versa.

You need to wrap your input with component, and add containerElement property with value 'label' ...

<RaisedButton
   containerElement='label' // <-- Just add me!
   label='My Label'>
   <input type="file" />
</RaisedButton>

You can read more about it in this GitHub issue.

EDIT: Update 2019.

Check at the bottom answer from @galki

TLDR;

<input
  accept="image/*"
  className={classes.input}
  style={{ display: 'none' }}
  id="raised-button-file"
  multiple
  type="file"
/>
<label htmlFor="raised-button-file">
  <Button variant="raised" component="span" className={classes.button}>
    Upload
  </Button>
</label> 

you should not use a.x for accumulator , Instead you can do like this `arr = [{x:1},{x:2},{x:4}]

arr.reduce(function(a,b){a + b.x},0)`

The issue is that you are trying to have multiple statements in an if without using {}. What you currently have is interpreted like:

if( choice==5 )
{
    System.out.println( ... );
}
break;
else
{
    //...
}

You really want:

if( choice==5 )
{
    System.out.println( ... );
    break;
}
else
{
    //...
}

Also, as Farce has stated, it would be better to use else if for all the conditions instead of if because if choice==1, it will still go through and check if choice==5, which would fail, and it will still go into your else block.

if( choice==1 )
    //...
else if( choice==2 )
    //...
else if( choice==3 )
    //...
else if( choice==4 )
    //...
else if( choice==5 )
{
    //...
}
else
    //...

A more elegant solution would be using a switch statement. However, break only breaks from the most inner "block" unless you use labels. So you want to label your loop and break from that if the case is 5:

LOOP:
for(;;)
{
    System.out.println("---> Your choice: ");
    choice = input.nextInt();
    switch( choice )
    {
        case 1:
            playGame();
            break;
        case 2:
            loadGame();
            break;
        case 2:
            options();
            break;
        case 4:
            credits();
            break;
        case 5:
            System.out.println("End of Game\n Thank you for playing with us!");
            break LOOP;
        default:
            System.out.println( ... );
    }
}

Instead of labeling the loop, you could also use a flag to tell the loop to stop.

bool finished = false;
while( !finished )
{
    switch( choice )
    {
        // ...
        case 5:
            System.out.println( ... )
            finished = true;
            break;
        // ...
    }
}

Using Chart.JS version 2.1.3, answers older than this one aren't valid anymore. Using getSegmentsAtEvent(event) method will output on console this message:

getSegmentsAtEvent is not a function

So i think it must be removed. I didn't read any changelog to be honest. To resolve that, just use getElementsAtEvent(event) method, as it can be found on the Docs.

Below it can be found the script to obtain effectively clicked slice label and value. Note that also retrieving label and value is slightly different.

var ctx = document.getElementById("chart-area").getContext("2d");
var chart = new Chart(ctx, config);

document.getElementById("chart-area").onclick = function(evt)
{   
    var activePoints = chart.getElementsAtEvent(evt);

    if(activePoints.length > 0)
    {
      //get the internal index of slice in pie chart
      var clickedElementindex = activePoints[0]["_index"];

      //get specific label by index 
      var label = chart.data.labels[clickedElementindex];

      //get value by index      
      var value = chart.data.datasets[0].data[clickedElementindex];

      /* other stuff that requires slice's label and value */
   }
}

Hope it helps.

With the new syntax of RxJS 5.5+, this becomes as the following:

// RxJS 6
import { EMPTY, empty, of } from "rxjs";

// rxjs 5.5+ (<6)
import { empty } from "rxjs/observable/empty";
import { of } from "rxjs/observable/of";

empty(); // deprecated use EMPTY
EMPTY;
of({});

Just one thing to keep in mind, EMPTY completes the observable, so it won't trigger next in your stream, but only completes. So if you have, for instance, tap, they might not get trigger as you wish (see an example below).

Whereas of({}) creates an Observable and emits next with a value of {} and then it completes the Observable.

E.g.:

EMPTY.pipe(
    tap(() => console.warn("i will not reach here, as i am complete"))
).subscribe();

of({}).pipe(
    tap(() => console.warn("i will reach here and complete"))
).subscribe();

Download file

For downloading you can use multiple ways as been explained above, moreover I will also provide my strategy for this scenario.

1. npm install --save react-download-link
2. import DownloadLink from "react-download-link";
3. React download link for client side cache data

   <DownloadLink 
       label="Download" 
       filename="fileName.txt"
       exportFile={() => "Client side cache data here…"}
   />
   

4. Download link for client side cache data with Promises

   <DownloadLink
       label="Download with Promise"
       filename="fileName.txt"
       exportFile={() => Promise.resolve("cached data here …")}
   />
   

5. Download link for data from URL with Promises Function to Fetch data from URL

    getDataFromURL = (url) => new Promise((resolve, reject) => {
       setTimeout(() => {

Happy coding! ;)

I know this question has been asked years ago but still wanted to share how I usually compile multiple c++ files.

1. Let's say you have 5 cpp files, all you have to do is use the * instead of typing each cpp files name E.g g++ -c *.cpp -o myprogram.
2. This will generate "myprogram"
3. run the program ./myprogram

that's all!!

The reason I'm using * is that what if you have 30 cpp files would you type all of them? or just use the * sign and save time :)

p.s Use this method only if you don't care about makefile.

move

struct body bodies[n];

to after

struct body
{
    double p[3];//position
    double v[3];//velocity
    double a[3];//acceleration
    double radius;
    double mass;
};

Rest all looks fine.

I'll let you in on a secret: the best way to use timeit is on the command line.

On the command line, timeit does proper statistical analysis: it tells you how long the shortest run took. This is good because all error in timing is positive. So the shortest time has the least error in it. There's no way to get negative error because a computer can't ever compute faster than it can compute!

So, the command-line interface:

%~> python -m timeit "1 + 2"
10000000 loops, best of 3: 0.0468 usec per loop

That's quite simple, eh?

You can set stuff up:

%~> python -m timeit -s "x = range(10000)" "sum(x)"
1000 loops, best of 3: 543 usec per loop

which is useful, too!

If you want multiple lines, you can either use the shell's automatic continuation or use separate arguments:

%~> python -m timeit -s "x = range(10000)" -s "y = range(100)" "sum(x)" "min(y)"
1000 loops, best of 3: 554 usec per loop

That gives a setup of

x = range(1000)
y = range(100)

and times

sum(x)
min(y)

If you want to have longer scripts you might be tempted to move to timeit inside a Python script. I suggest avoiding that because the analysis and timing is simply better on the command line. Instead, I tend to make shell scripts:

 SETUP="

 ... # lots of stuff

 "

 echo Minmod arr1
 python -m timeit -s "$SETUP" "Minmod(arr1)"

 echo pure_minmod arr1
 python -m timeit -s "$SETUP" "pure_minmod(arr1)"

 echo better_minmod arr1
 python -m timeit -s "$SETUP" "better_minmod(arr1)"

 ... etc

This can take a bit longer due to the multiple initialisations, but normally that's not a big deal.

But what if you want to use timeit inside your module?

Well, the simple way is to do:

def function(...):
    ...

timeit.Timer(function).timeit(number=NUMBER)

and that gives you cumulative (not minimum!) time to run that number of times.

To get a good analysis, use .repeat and take the minimum:

min(timeit.Timer(function).repeat(repeat=REPEATS, number=NUMBER))

You should normally combine this with functools.partial instead of lambda: ... to lower overhead. Thus you could have something like:

from functools import partial

def to_time(items):
    ...

test_items = [1, 2, 3] * 100
times = timeit.Timer(partial(to_time, test_items)).repeat(3, 1000)

# Divide by the number of repeats
time_taken = min(times) / 1000

You can also do:

timeit.timeit("...", setup="from __main__ import ...", number=NUMBER)

which would give you something closer to the interface from the command-line, but in a much less cool manner. The "from __main__ import ..." lets you use code from your main module inside the artificial environment created by timeit.

It's worth noting that this is a convenience wrapper for Timer(...).timeit(...) and so isn't particularly good at timing. I personally far prefer using Timer(...).repeat(...) as I've shown above.

Warnings

There are a few caveats with timeit that hold everywhere.

• Overhead is not accounted for. Say you want to time x += 1, to find out how long addition takes:

  >>> python -m timeit -s "x = 0" "x += 1"
  10000000 loops, best of 3: 0.0476 usec per loop
  

  Well, it's not 0.0476 µs. You only know that it's less than that. All error is positive.

  So try and find pure overhead:

  >>> python -m timeit -s "x = 0" ""      
  100000000 loops, best of 3: 0.014 usec per loop
  

  That's a good 30% overhead just from timing! This can massively skew relative timings. But you only really cared about the adding timings; the look-up timings for x also need to be included in overhead:

  >>> python -m timeit -s "x = 0" "x"
  100000000 loops, best of 3: 0.0166 usec per loop
  

  The difference isn't much larger, but it's there.

• Mutating methods are dangerous.

  >>> python -m timeit -s "x = [0]*100000" "while x: x.pop()"
  10000000 loops, best of 3: 0.0436 usec per loop
  

  But that's completely wrong! x is the empty list after the first iteration. You'll need to reinitialize:

  >>> python -m timeit "x = [0]*100000" "while x: x.pop()"
  100 loops, best of 3: 9.79 msec per loop
  

  But then you have lots of overhead. Account for that separately.

  >>> python -m timeit "x = [0]*100000"                   
  1000 loops, best of 3: 261 usec per loop
  

  Note that subtracting the overhead is reasonable here only because the overhead is a small-ish fraction of the time.

  For your example, it's worth noting that both Insertion Sort and Tim Sort have completely unusual timing behaviours for already-sorted lists. This means you will require a random.shuffle between sorts if you want to avoid wrecking your timings.

Default values are only used if the arguments are not specified. In your case you did specify the arguments - both were supplied, with a value of NULL. (Yes, in this case NULL is considered a real value :-). Try:

EXEC TEST()

Share and enjoy.

Addendum: The default values for procedure parameters are certainly buried in a system table somewhere (see the SYS.ALL_ARGUMENTS view), but getting the default value out of the view involves extracting text from a LONG field, and is probably going to prove to be more painful than it's worth. The easy way is to add some code to the procedure:

CREATE OR REPLACE PROCEDURE TEST(X IN VARCHAR2 DEFAULT 'P',
                                 Y IN NUMBER DEFAULT 1)
AS
  varX VARCHAR2(32767) := NVL(X, 'P');
  varY NUMBER          := NVL(Y, 1);
BEGIN
  DBMS_OUTPUT.PUT_LINE('X=' || varX || ' -- ' || 'Y=' || varY);
END TEST;

@LiviuT's answer is awesome, but seems to leave lots of folks wondering how to re-access the handler's tear-down function from another $scope or function, if you want to destroy it from a place other than where it was created. @?????? ?????????'s answer works just great, but isn't very idiomatic. (And relies on what's supposed to be a private implementation detail, which could change any time.) And from there, it just gets more complicated...

I think the easy answer here is to simply carry a reference to the tear-down function (offCallMeFn in his example) in the handler itself, and then call it based on some condition; perhaps an arg that you include on the event you $broadcast or $emit. Handlers can thus tear down themselves, whenever you want, wherever you want, carrying around the seeds of their own destruction. Like so:

// Creation of our handler:
var tearDownFunc = $rootScope.$on('demo-event', function(event, booleanParam) {
    var selfDestruct = tearDownFunc;
    if (booleanParam === false) {
        console.log('This is the routine handler here. I can do your normal handling-type stuff.')
    }
    if (booleanParam === true) {
        console.log("5... 4... 3... 2... 1...")
        selfDestruct();
    }
});

// These two functions are purely for demonstration
window.trigger = function(booleanArg) {
    $scope.$emit('demo-event', booleanArg);
}
window.check = function() {
    // shows us where Angular is stashing our handlers, while they exist
    console.log($rootScope.$$listeners['demo-event'])
};

// Interactive Demo:

>> trigger(false);
// "This is the routine handler here. I can do your normal handling-type stuff."

>> check();
// [function] (So, there's a handler registered at this point.)  

>> trigger(true);
// "5... 4... 3... 2... 1..."

>> check();
// [null] (No more handler.)

>> trigger(false);
// undefined (He's dead, Jim.)

Two thoughts:

1. This is a great formula for a run-once handler. Just drop the conditionals and run selfDestruct as soon as it has completed its suicide mission.
2. I wonder about whether the originating scope will ever be properly destroyed and garbage-collected, given that you're carrying references to closured variables. You'd have to use a million of these to even have it be a memory problem, but I'm curious. If anybody has any insight, please share.

Here is a fast and simple solution.

Pick two random numbers in the range (0, 1), namely a and b. If b < a, swap them. Your point is (b*R*cos(2*pi*a/b), b*R*sin(2*pi*a/b)).

You can think about this solution as follows. If you took the circle, cut it, then straightened it out, you'd get a right-angled triangle. Scale that triangle down, and you'd have a triangle from (0, 0) to (1, 0) to (1, 1) and back again to (0, 0). All of these transformations change the density uniformly. What you've done is uniformly picked a random point in the triangle and reversed the process to get a point in the circle.

If you can add another wrapping div "block3" you could do something like this.

 <html>
      <head>
      <style type="text/css">
      .block1 {color:red;width:120px;border:1px solid green; height: 100px;}
      .block3 {float:left; width:10px;}
      .block2 {color:blue;width:70px;border:2px solid black;position:relative;float:right;}
      </style>
      </head>

    <body>
    <div class='block1'>

        <div class='block3'>
            <p>text1</p>
            <p>text2</p>
        </div>

        <div class='block2'>block2</DIV>

    </div>

    </body>

This is because the Python exec are not in the search path of your operating system. In windows, start CMD. Type in

setx PATH PythonPath

where PythonPath is usually C:\Python27 or C:\Python33 or C:\Users\<Your User Name>\AppData\Local\Programs\Python\Python37 depending on your Python version. After restarting the CMD, you should get see outcomes when typing

If you're using dom4j, you can just do:

Document document = DocumentHelper.parseText(text);

(dom4j now found here: https://github.com/dom4j/dom4j)

Sure. You could use CSS3 text-shadow :

text-shadow: 0 0 2px #fff;

However it wont show in all browsers right away. Using a script library like Modernizr will help getting it right in most browsers though.

Use Django Serializer with python format,

from django.core import serializers

qs = SomeModel.objects.all()
serialized_obj = serializers.serialize('python', qs)

What's difference between json and python format?

The json format will return the result as str whereas python will return the result in either list or OrderedDict

No. We cannot alter the constraint, only thing we can do is drop and recreate it

ALTER TABLE [TABLENAME] DROP CONSTRAINT [CONSTRAINTNAME]

Foreign Key Constraint

Alter Table Table1 Add Constraint [CONSTRAINTNAME] Foreign Key (Column) References Table2 (Column) On Update Cascade On Delete Cascade

Primary Key constraint

Alter Table Table add constraint [Primary Key] Primary key(Column1,Column2,.....)

Here is a pure JavaScript solution (without jQuery)

var _Utils = function ()
{
    this.findChildById = function (element, childID, isSearchInnerDescendant) // isSearchInnerDescendant <= true for search in inner childern 
    {
        var retElement = null;
        var lstChildren = isSearchInnerDescendant ? Utils.getAllDescendant(element) : element.childNodes;

        for (var i = 0; i < lstChildren.length; i++)
        {
            if (lstChildren[i].id == childID)
            {
                retElement = lstChildren[i];
                break;
            }
        }

        return retElement;
    }

    this.getAllDescendant = function (element, lstChildrenNodes)
    {
        lstChildrenNodes = lstChildrenNodes ? lstChildrenNodes : [];

        var lstChildren = element.childNodes;

        for (var i = 0; i < lstChildren.length; i++) 
        {
            if (lstChildren[i].nodeType == 1) // 1 is 'ELEMENT_NODE'
            {
                lstChildrenNodes.push(lstChildren[i]);
                lstChildrenNodes = Utils.getAllDescendant(lstChildren[i], lstChildrenNodes);
            }
        }

        return lstChildrenNodes;
    }        
}
var Utils = new _Utils;

Example of use:

var myDiv = document.createElement("div");
myDiv.innerHTML = "<table id='tableToolbar'>" +
                        "<tr>" +
                            "<td>" +
                                "<div id='divIdToSearch'>" +
                                "</div>" +
                            "</td>" +
                        "</tr>" +
                    "</table>";

var divToSearch = Utils.findChildById(myDiv, "divIdToSearch", true);

Yes. The only way would be to drop the constraint with an Alter table then recreate it.

ALTER TABLE <Table_Name>
DROP CONSTRAINT <constraint_name>

ALTER TABLE <Table_Name>
ADD CONSTRAINT <constraint_name> PRIMARY KEY (<Column1>,<Column2>)

I have a BindingList<> object bind as a data source to dataGridView.

BindingList x1;
x1 = new BindingList<sourceObject>();
BindingSource bsx1 = new BindingSource();
bsx1.DataSource = x1;
dataGridView1.DataSource = bsx1;

When I clicked the column header, no sorting takes place. I used the SortableBindingList answer provided by Tom Bushell. Having included two source files into my project

1. SortableBindingList.cs
2. PropertyComparer.cs

Then this change is made to my code:

Be.Timvw.Framework.ComponentModel.SortableBindingList x1;                       // 1
x1 = new Be.Timvw.Framework.ComponentModel.SortableBindingList<sourceObject>(); // 2
BindingSource bsx1 = new BindingSource();
bsx1.DataSource = x1;
dataGridView1.DataSource = bsx1;

After these changes I performed a build on my program. I am now able to sort by clicking the column headers. Only two lines need changing, they are highlighted in the code snippet above by trailing comments.

Actually you're close to your goal, you just need to use nodes() method to split your rows and then get values:

select
    s.SqmId,
    m.c.value('@id', 'varchar(max)') as id,
    m.c.value('@type', 'varchar(max)') as type,
    m.c.value('@unit', 'varchar(max)') as unit,
    m.c.value('@sum', 'varchar(max)') as [sum],
    m.c.value('@count', 'varchar(max)') as [count],
    m.c.value('@minValue', 'varchar(max)') as minValue,
    m.c.value('@maxValue', 'varchar(max)') as maxValue,
    m.c.value('.', 'nvarchar(max)') as Value,
    m.c.value('(text())[1]', 'nvarchar(max)') as Value2
from sqm as s
    outer apply s.data.nodes('Sqm/Metrics/Metric') as m(c)

A 2019 answer if you're using .NET Core - use the Nuget ToDataTable library. Advantages:

• Better performance than reflection or using DataTableProxy
• Also creates SqlParameters for use with SQL Server Table-Valued Parameters

Disclaimer - I'm the author of ToDataTable

Performance - I span up some Benchmark .Net tests and included them in the ToDataTable repo. The results were as follows:

Method overriding is when a child class redefines the same method as a parent class, with the same parameters. For example, the standard Java class java.util.LinkedHashSet extends java.util.HashSet. The method add() is overridden in LinkedHashSet. If you have a variable that is of type HashSet, and you call its add() method, it will call the appropriate implementation of add(), based on whether it is a HashSet or a LinkedHashSet. This is called polymorphism.

Method overloading is defining several methods in the same class, that accept different numbers and types of parameters. In this case, the actual method called is decided at compile-time, based on the number and types of arguments. For instance, the method System.out.println() is overloaded, so that you can pass ints as well as Strings, and it will call a different version of the method.

Both of your examples should behave pretty much the same.

A value returned inside a then() handler becomes the resolution value of the promise returned from that then(). If the value returned inside the .then is a promise, the promise returned by then() will "adopt the state" of that promise and resolve/reject just as the returned promise does.

In your first example, you return "bbb" in the first then() handler, so "bbb" is passed into the next then() handler.

In your second example, you return a promise that is immediately resolved with the value "bbb", so "bbb" is passed into the next then() handler. (The Promise.resolve() here is extraneous).

The outcome is the same.

If you can show us an example that actually exhibits different behavior, we can tell you why that is happening.

The above is correct but for a more general answer it is not enough. I needed to nest ng-repeat, but stay on the same html level, meaning write the elements in the same parent. The tags array contain tag(s) that also have a tags array. It is actually a tree.

[{ name:'name1', tags: [
  { name: 'name1_1', tags: []},
  { name: 'name1_2', tags: []}
  ]},
 { name:'name2', tags: [
  { name: 'name2_1', tags: []},
  { name: 'name2_2', tags: []}
  ]}
]

So here is what I eventually did.

<div ng-repeat-start="tag1 in tags" ng-if="false"></div>
    {{tag1}},
  <div ng-repeat-start="tag2 in tag1.tags" ng-if="false"></div>
    {{tag2}},
  <div ng-repeat-end ng-if="false"></div>
<div ng-repeat-end ng-if="false"></div>

Note the ng-if="false" that hides the start and end divs.

It should print

name1,name1_1,name1_2,name2,name2_1,name2_2,

The problem was the box "open new connection" that was checked. So I couldn't use my temporary table.

You could use this function which is doing the same as the eval() function, but in a simple manner, using a function.

def numeric(equation):
    if '+' in equation:
        y = equation.split('+')
        x = int(y[0])+int(y[1])
    elif '-' in equation:
        y = equation.split('-')
        x = int(y[0])-int(y[1])
    return x

Aggregation of all postgres sessions per their status (how many are idle, how many doing something...)

select state, count(*) from pg_stat_activity  where pid <> pg_backend_pid() group by 1 order by 1;

What you want is...

new File(uri.getPath());

... and not...

new File(uri.toString());

Note: uri.toString() returns a String in the format: "file:///mnt/sdcard/myPicture.jpg", whereas uri.getPath() returns a String in the format: "/mnt/sdcard/myPicture.jpg".

Based on the error you showed ('footballforum' is missing required Java project: 'ApiDemos'), I would check your build path. Right-click the footballforum project and choose Build Path > Configure Build Path. Make sure ApiDemos is on the projects tab of the build path options.

If I understand you correctly, you need to use -SearchBase:

Get-ADUser -SearchBase "OU=Accounts,OU=RootOU,DC=ChildDomain,DC=RootDomain,DC=com" -Filter *

Note that Get-ADUser defaults to using

 -SearchScope Subtree

so you don't need to specify it. It's this that gives you all sub-OUs (and sub-sub-OUs, etc.).

If you have DotPeek from JetBrains, you can see it in Assembly Explorer.

The easiest way is this.

The solution discussed here worked well for me. This solution uses built-in cuda functions and is very simple to implement.

The relevant code is copied below:

#include <stdio.h>
#include <stdlib.h>

__global__ void foo(int *ptr)
{
  *ptr = 7;
}

int main(void)
{
  foo<<<1,1>>>(0);

  // make the host block until the device is finished with foo
  cudaDeviceSynchronize();

  // check for error
  cudaError_t error = cudaGetLastError();
  if(error != cudaSuccess)
  {
    // print the CUDA error message and exit
    printf("CUDA error: %s\n", cudaGetErrorString(error));
    exit(-1);
  }

  return 0;
}

                        {

As string data types have variable length, it is by default stored as object type. I faced this problem after treating missing values too. Converting all those columns to type 'category' before label encoding worked in my case.

df[cat]=df[cat].astype('category')

And then check df.dtypes and perform label encoding.

It is important to note the following difference between the two techniques:

$Str="This is the<BR />source string<BR />ALL RIGHT"
$Str.Split("<BR />")
This
is
the
(multiple blank lines)
source
string
(multiple blank lines)
ALL
IGHT
$Str -Split("<BR />")
This is the
source string
ALL RIGHT 

From this you can see that the string.split() method:

• performs a case sensitive split (note that "ALL RIGHT" his split on the "R" but "broken" is not split on the "r")
• treats the string as a list of possible characters to split on

While the -split operator:

• performs a case-insensitive comparison
• only splits on the whole string

We have two array a and b. the code what did here is array a value is pushed into array b.

let a = [2, 4, 6, 8, 9, 15]

function transform(a) {
    let b = ['4', '16', '64']
    a.forEach(function(e) {
        b.push(e.toString());
    });
    return b;
}

transform(a)

[ '4', '16', '64', '2', '4', '6', '8', '9', '15' ]

None of the above solutions worked for me on localhost. I even allowed access from less secure apps, allowed access through display unlock captcha and set the verify peer and verify peer name to false for SSL.

Eventually, I used the open source SMTP testing solution of MailHog. The steps are as follows:

1. Download the latest version of MailHog for your OS
2. Specify the following settings in your .env file

MAIL_DRIVER=smtp

MAIL_HOST=127.0.0.1

MAIL_PORT=1025

MAIL_USERNAME=testuser

MAIL_PASSWORD=testpwd

MAIL_ENCRYPTION=null

[email protected]

3. Run the downloaded file of MailHog
4. Send Email
5. Check sent email by going to localhost:8025

import random
q=2
o=1
list  =[r'a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','s','0','1','2','3','4','5','6','7','8','9','0']
while(q>o):
    print("")

    for i in range(1,128):
        x=random.choice(list)
        print(x,end="")

Here length of string can be changed in for loop i.e for i in range(1,length) It is simple algorithm which is easy to understand. it uses list so you can discard characters that you do not need.

try:
   a = b[n]
except IndexError:
   a = default

Edit: I removed the check for TypeError - probably better to let the caller handle this.

I tried this, but it is not possible to remove "Watch on YouTube" icon. Following solution of mine does not remove the icon itself but "blocks" the mouse hover so that watch on YouTube is not click-able. I added a div over icon, so no mouseover will be affected for that logo.

 <div class="holder">
     <div class="frame" id="player" style="height 350"></div>
     <div class="bar" id="bottom-layer">.</div>
 </div>

Where frame is my embedded player. include following to your css file

.holder{
position:relative;
width:640px;
height:350px;
}

.frame{
width: 100%;
height:100%;
}

.bar{
position:absolute;
bottom:0;
right:0;
width:100%;
height:40px;
}

This is not full solution but helps you if you are bothered with users' getting full youtube url.

Simplest way IMO is to include an ID and runat server tag on all your elements.

<div id="MYDIV" runat="server" />

Since it sounds like these are dynamically inserted controls, you might appreciate FindControl().

Also is possible to assign different action implementing onCancelListener:

alertDialog.setOnCancelListener(new DialogInterface.OnCancelListener(){                   
    @Override
    public void onCancel(DialogInterface dialogInterface) {
        //Your custom logic
    } 
});

I know that this already has plenty of answers and is a rather old question. But I just came up with this neat one-liner:

JSON.parse(JSON.stringify(raw, ['key', 'value', 'item1', 'item3']))

That returns another object with just the whitelisted attributes. Note that the key and value is included in the list.

I faced the same issue, I tried the below solution and it worked for me In Android SDK Manager Window, click on Tools->Options-> under "Others", check "Force https://... sources to be fetched using http://..."

You should be able to do something like this:

byte[] bitmap = GetYourImage();

using(Image image = Image.FromStream(new MemoryStream(bitmap)))
{
    image.Save("output.jpg", ImageFormat.Jpeg);  // Or Png
}

Look here for more info.

Hopefully this helps.

pyinstaller yourfile.py -F --onefile

This creates a standalone EXE file on Windows.

Important note 1: The EXE file will be generated in a folder named 'dist'.

Important note 2: Do not forget --onefile flag

You can install PyInstaller using pip install PyInstaller

NOTE: In rare cases there are hidden dependencies...so if you run the EXE file and get missing library error (win32timezone in the example below) then use something like this:

pyinstaller --hiddenimport win32timezone -F "Backup Program.py"

If you don't want to edit PATH variable, go to the platform-tools directory where the SDK is installed, and the command is there.

You can use it like this:

1. Go to the directory where you placed the SDK:

   cd /Users/mansour/Library/Developer/Android/sdk/platform-tools

2. Type the adb command with ./ to use it from the current directory.

   ./adb tcpip 5555

   ./adb devices

   ./adb connect 192.168.XXX.XXX

It is also possible, but you have to mention the same field names in select.

SELECT t1.name, t2.name FROM t1
LEFT JOIN t2 ON t1.id = t2.id
UNION
SELECT t1.name, t2.name FROM t2
LEFT JOIN t1 ON t1.id = t2.id

Below function will strip the empty spces and return the strings without quotes. If there are no quotes then it will return same string(stripped)

def removeQuote(str):
str = str.strip()
if re.search("^[\'\"].*[\'\"]$",str):
    str = str[1:-1]
    print("Removed Quotes",str)
else:
    print("Same String",str)
return str

You can use the following below with document.title = 'Home Page'

import React from 'react'
import { Component } from 'react-dom'


class App extends Component{
  componentDidMount(){
    document.title = "Home Page"
  }

  render(){
    return(
      <p> Title is now equal to Home Page </p>
    )
  }
}

ReactDOM.render(
  <App />,
  document.getElementById('root')
);

or You can use this npm package npm i react-document-title

import React from 'react'
import { Component } from 'react-dom'
import DocumentTitle from 'react-document-title';


class App extends Component{


  render(){
    return(
      <DocumentTitle title='Home'>
        <h1>Home, sweet home.</h1>
      </DocumentTitle>
    )
  }
}

ReactDOM.render(
  <App />,
  document.getElementById('root')
);

Happy Coding!!!

Intellij IDEA 15: File->Project Structure...->Project Settings->Libraries

Check out the Node js modules wiki page. They have listed all the templating engines supporting node.js.

The problem is an issue of semantic meaning (as BoltClock mentions) and visual rendering.

Originally HTML used <b> and <i> for these purposes, entirely stylistic commands, laid down in the semantic environment of the document markup. CSS is an attempt to separate out as far as possible the stylistic elements of the medium. Thus style information such as bold and italics should go in CSS.

<strong> and <em> were introduced to fill the semantic need for text to be marked as more important or stressed. They have default stylistic interpretations akin to bold and italic, but they are not bound to that fate.

do not forget to insert (or unCommanet) this line at the beginning of your pod file:

platform :iOS, '9.0'

that saves my day

I call dispose anytime an object implements IDisposeable. It's there for a reason.

DataSets can be huge memory hogs. The sooner they can be marked for clean up, the better.

update

It's been 5 years since I answered this question. I still agree with my answer. If there is a dispose method, it should be called when you are done with the object. The IDispose interface was implemented for a reason.

Dan, it's just you're accessing the protected field instead of properties.

See for example this line in your Main(...):

myClub.distance = Console.ReadLine();

myClub.distance is the protected field, while you wanted to set the property mydistance.

I'm just giving you some hint, I'm not going to correct your code, since this is homework! ;)

You will get the un passed argument value as undefined. But in your case you have to pass at least null value in the first argument.

Or you have to change the method definition like

my_function = function(options, content) { action }

*sigh*

No, typechecking arguments in python is not necessary. It is never necessary.

If your code accepts either a string or a dict object, your design is broken.

That comes from the fact that if you don't know already the type of an object in your own program, then you're doing something wrong already.

Typechecking hurts code reuse and reduces performance. Having a function that performs different things depending on the type of the object passed is bug-prone and has a behavior harder to understand and maintain.

You have the following saner options:

1) Make a function unique_values that converts dicts in unique lists of values:

def unique_values(some_dict):
    return list(set(some_dict.values()))

Make your function assume the argument passed is always a list. That way, if you need to pass a string to the function, you just do:

myfunction([some_string])

If you need to pass it a dict, you do:

myfunction(unique_values(some_dict))

That's your best option, it is clean, easy to understand and maintain. Anyone reading the code immediatelly understands what is happening, and you don't have to typecheck.

2) Make two functions, one that accepts lists of strings and one that accepts dicts. You can make one call the other internally, in the most convenient way (myfunction_dict can create a list of strings and call myfunction_list).

In any case, don't typecheck. It is completely unnecessary and has only downsides. Refactor your code instead in a way you don't need to typecheck. You only get benefits in doing so, both in short and long run.

To slow down your game, use pygame.clock.tick(10)

Quickest way I can come up with is:

var sunday = DateTime.Today.AddDays(-(int)DateTime.Today.DayOfWeek);

If you would like any other day of the week to be your start date all you need to do is add the DayOfWeek value to the end

var monday = DateTime.Today.AddDays(-(int)DateTime.Today.DayOfWeek + (int)DayOfWeek.Monday);

var tuesday = DateTime.Today.AddDays(-(int)DateTime.Today.DayOfWeek + (int)DayOfWeek.Tuesday); 

I ended up coding a custom solution (Firefox extension) that does this. I think by the time I developed it, the commandline mentioned in enreas wasn't there.

The Firefox extension is CmdShots. It's a good option if you need finer degree of control over the process of taking the screenshot (or you want to do some HTML/JS modifications and image processing).

You can use it and abuse it. I decided to keep it unlicensed, so you are free to play with it as you want.

Well it depends on what you have in your table.

its one of the following If you have only one table

var count = $('#gvPerformanceResult tr').length;

If you are concerned about sub tables but this wont work with tbody and thead (if you use them)

var count = $('#gvPerformanceResult>tr').length;

Where by this will work (but is quite frankly overkill.)

var count = $('#gvPerformanceResult>tbody>tr').length;

Tried most of the things here to no avail, but finally found a fix for my machine, so thought I'd share it:

Following previous advice in another question, I had used netsh to add :: to iplisten. It turns out undoing that was my solution, by simply replacing add in their advice:

netsh http delete iplisten ipaddress=::

You can also do this manually by deleting HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters\ListenOnlyList from the registry and restarting the service/your PC.

High-Level Design (HLD) involves decomposing a system into modules, and representing the interfaces & invocation relationships among modules. An HLD is referred to as software architecture.

LLD, also known as a detailed design, is used to design internals of the individual modules identified during HLD i.e. data structures and algorithms of the modules are designed and documented.

Now, HLD and LLD are actually used in traditional Approach (Function-Oriented Software Design) whereas, in OOAD, the system is seen as a set of objects interacting with each other.

As per the above definitions, a high-level design document will usually include a high-level architecture diagram depicting the components, interfaces, and networks that need to be further specified or developed. The document may also depict or otherwise refer to work flows and/or data flows between component systems.

Class diagrams with all the methods and relations between classes come under LLD. Program specs are covered under LLD. LLD describes each and every module in an elaborate manner so that the programmer can directly code the program based on it. There will be at least 1 document for each module. The LLD will contain - a detailed functional logic of the module in pseudo code - database tables with all elements including their type and size - all interface details with complete API references(both requests and responses) - all dependency issues - error message listings - complete inputs and outputs for a module.

The first answer is too complex, historic, and uninformative for my tastes.

It's actually rather simple. Docker provides for a functionality called multi-stage builds the basic idea here is to,

• Free you from having to manually remove what you don't want, by forcing you to whitelist what you do want,
• Free resources that would otherwise be taken up because of Docker's implementation.

Let's start with the first. Very often with something like Debian you'll see.

RUN apt-get update \ 
  && apt-get dist-upgrade \
  && apt-get install <whatever> \
  && apt-get clean

We can explain all of this in terms of the above. The above command is chained together so it represents a single change with no intermediate Images required. If it was written like this,

RUN apt-get update ;
RUN apt-get dist-upgrade;
RUN apt-get install <whatever>;
RUN apt-get clean;

It would result in 3 more temporary intermediate Images. Having it reduced to one image, there is one remaining problem: apt-get clean doesn't clean up artifacts used in the install. If a Debian maintainer includes in his install a script that modifies the system that modification will also be present in the final solution (see something like pepperflashplugin-nonfree for an example of that).

By using a multi-stage build you get all the benefits of a single changed action, but it will require you to manually whitelist and copy over files that were introduced in the temporary image using the COPY --from syntax documented here. Moreover, it's a great solution where there is no alternative (like an apt-get clean), and you would otherwise have lots of un-needed files in your final image.

See also

• Multi-stage builds
• COPY syntax

You can try this:

var names = ["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"];
var uniqueNames = [];
$.each(names, function(i, el){
if($.inArray(el, uniqueNames) === -1) uniqueNames.push(el);
});

Easiest way to find duplicate values in a JavaScript array

There is another way to accomplish that (described in more details in Stephen Walther's Pager example

Essentially, you create a link in the view:

Html.ActionLink("Next page", "Index", routeData)

In routeData you can specify name/value pairs (e.g., routeData["page"] = 5), and in the controller Index function corresponding parameters receive the value. That is,

public ViewResult Index(int? page)

will have page passed as 5. I have to admit, it's quite unusual that string ("page") automagically becomes a variable - but that's how MVC works in other languages as well...

For people coming from Google, this question is not about data attributes - OP added a non-standard attribute to their HTML object, and wondered how to set it.

However, you should not add custom attributes to your properties - you should use data attributes - e.g. OP should have used data-icon, data-url, data-target, etc.

In any event, it turns out that the way you set these attributes via JavaScript is the same for both cases. Use:

ele.setAttribute(attributeName, value);

to change the given attribute attributeName to value for the DOM element ele.

For example:

document.getElementById("someElement").setAttribute("data-id", 2);

Note that you can also use .dataset to set the values of data attributes, but as @racemic points out, it is 62% slower (at least in Chrome on macOS at the time of writing). So I would recommend using the setAttribute method instead.

I wrote this npm package stringinject https://www.npmjs.com/package/stringinject which allows you to do the following

var string = stringInject("this is a {0} string for {1}", ["test", "stringInject"]);

which will replace the {0} and {1} with the array items and return the following string

"this is a test string for stringInject"

or you could replace placeholders with object keys and values like so:

var str = stringInject("My username is {username} on {platform}", { username: "tjcafferkey", platform: "GitHub" });

"My username is tjcafferkey on Github" 

Everything you need here can be found in this quickstart guide. A straightforward solution would be [A-Za-z][A-Za-z]\d\d\d\d\d\d or [A-Za-z]{2}\d{6}.

If you want to accept only capital letters then replace [A-Za-z] with [A-Z].

Use include_once instead.
This error means that you have already included this file.

include_once(LIB.'/class.php');

You have said you can only load scripts from your own site (self). You have then tried to load a script from another site (www.google.com) and, because you've restricted this, you can't. That's the whole point of Content Security Policy (CSP).

You can change your first line to:

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval' http://www.google.com">

Or, alternatively, it may be worth removing that line completely until you find out more about CSP. Your current CSP is pretty lax anyway (allowing unsafe-inline, unsafe-eval and a default-src of *), so it is probably not adding too much value, to be honest.

I have 4 ships to set on one single map, so I use the Google Developers example and then twisted it

https://developers.google.com/maps/documentation/javascript/examples/icon-complex

In the function bellow I set 3 more color options:

function setMarkers(map, locations) {
...
var image = {
    url: 'img/bullet_amarelo.png',
    // This marker is 20 pixels wide by 32 pixels tall.
    size: new google.maps.Size(40, 40),
    // The origin for this image is 0,0.
    origin: new google.maps.Point(0,0),
    // The anchor for this image is the base of the flagpole at 0,32.
    anchor: new google.maps.Point(0, 40)
  };
  var image1 = {
            url: 'img/bullet_azul.png',
            // This marker is 20 pixels wide by 32 pixels tall.
            size: new google.maps.Size(40, 40),
            // The origin for this image is 0,0.
            origin: new google.maps.Point(0,0),
            // The anchor for this image is the base of the flagpole at 0,32.
            anchor: new google.maps.Point(0, 40)
          };
  var image2 = {
          url: 'img/bullet_vermelho.png',
          // This marker is 20 pixels wide by 32 pixels tall.
          size: new google.maps.Size(40, 40),
          // The origin for this image is 0,0.
          origin: new google.maps.Point(0,0),
          // The anchor for this image is the base of the flagpole at 0,32.
          anchor: new google.maps.Point(0, 40)
        };
  var image3 = {
          url: 'img/bullet_verde.png',
          // This marker is 20 pixels wide by 32 pixels tall.
          size: new google.maps.Size(40, 40),
          // The origin for this image is 0,0.
          origin: new google.maps.Point(0,0),
          // The anchor for this image is the base of the flagpole at 0,32.
          anchor: new google.maps.Point(0, 40)
        };
...
}

And in the FOR bellow I set one color for each ship:

for (var i = 0; i < locations.length; i++) {
...
    if (i==0) var imageV=image;
    if (i==1) var imageV=image1;
    if (i==2) var imageV=image2;
    if (i==3) var imageV=image3;
...
# remember to change icon: image to icon: imageV
}

The final result:

Wow, only 17 answers. The zen of python says "There should be one-- and preferably only one --obvious way to do it."

So here is an 18th way to do it: The tabulate package supports a bunch of data types that it can display as tables, here is a simple example adapted from their docs:

from tabulate import tabulate

table = [["Sun",696000,1989100000],
         ["Earth",6371,5973.6],
         ["Moon",1737,73.5],
         ["Mars",3390,641.85]]

print(tabulate(table, headers=["Planet","R (km)", "mass (x 10^29 kg)"]))

which outputs

Planet      R (km)    mass (x 10^29 kg)
--------  --------  -------------------
Sun         696000           1.9891e+09
Earth         6371        5973.6
Moon          1737          73.5
Mars          3390         641.85

You only need a single line of code to set the border around every cell in the range:

Range("A1:F20").Borders.LineStyle = xlContinuous

It's also easy to apply multiple effects to the border around each cell.

For example:

Sub RedOutlineCells()
    Dim rng As Range

    Set rng = Range("A1:F20")

    With rng.Borders
        .LineStyle = xlContinuous
        .Color = vbRed
        .Weight = xlThin
    End With
End Sub

No, <!-- ... --> is the only comment syntax in HTML.

If you are looking for the last row of a column, use:

Sub SelectFirstColumn()
   SelectEntireColumn (1)
End Sub

Sub SelectSecondColumn()
    SelectEntireColumn (2)
End Sub

Sub SelectEntireColumn(columnNumber)
    Dim LastRow
    Sheets("sheet1").Select
    LastRow = ActiveSheet.Columns(columnNumber).SpecialCells(xlLastCell).Row

    ActiveSheet.Range(Cells(1, columnNumber), Cells(LastRow, columnNumber)).Select
End Sub

Other commands you will need to get familiar with are copy and paste commands:

Sub CopyOneToTwo()
    SelectEntireColumn (1)
    Selection.Copy

    Sheets("sheet1").Select
    ActiveSheet.Range("B1").PasteSpecial Paste:=xlPasteValues
End Sub

Finally, you can reference worksheets in other workbooks by using the following syntax:

Dim book2
Set book2 = Workbooks.Open("C:\book2.xls")
book2.Worksheets("sheet1")

var scrollBottom = $(window).scrollTop() + $(window).height();

You can only use await in an async method, and Main cannot be async.

You'll have to use your own async-compatible context, call Wait on the returned Task in the Main method, or just ignore the returned Task and just block on the call to Read. Note that Wait will wrap any exceptions in an AggregateException.

If you want a good intro, see my async/await intro post.

In IE8 using .Net, setting the iframe.src for the first time is ok, but setting the iframe.src for the second time is not raising the page_load of the iframed page. To solve it i used iframe.contentDocument.location.href = "NewUrl.htm".

Discover it when used jQuery thickBox and tried to reopen same page in the thickbox iframe. Then it just showed the earlier page that was opened.

Give your parent div position: relative, then give your child div position: absolute, this will absolute position the div inside of its parent, then you can give the child bottom: 0px;

Since version 2.1 of the Maven Dependency Plugin, there is a dependency:get goal for this purpose. To make sure you are using the right version of the plugin, you'll need to use the "fully qualified name":

mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get \
    -DrepoUrl=http://download.java.net/maven/2/ \
    -Dartifact=robo-guice:robo-guice:0.4-SNAPSHOT

I am writing the swift version of the accepted answer here, incase if someone finds it usefull, the code is written swift 2,

You can download the required files from SampleCode

Add Reachability.h and Reachability.m file to your project,

Now one will need to create Bridging-Header.h file if none exists for your project,

Inside your Bridging-Header.h file add this line :

#import "Reachability.h"

Now in order to check for Internet Connection

static func isInternetAvailable() -> Bool {
    let networkReachability : Reachability = Reachability.reachabilityForInternetConnection()
    let networkStatus : NetworkStatus = networkReachability.currentReachabilityStatus()

    if networkStatus == NotReachable {
        print("No Internet")
        return false
    } else {
        print("Internet Available")
        return true
    }

}

Whether or not YouTube videos play in HTML5 format depends on the setting at https://www.youtube.com/html5, per browser. Chrome prefers HTML5 playback automatically, but even the latest Firefox and Internet Explorer still use Flash if it is installed on the machine.

The parameter html5=1 does not do anything (anymore) now. (Note it is not even listed at https://developers.google.com/youtube/player_parameters.)

In my particular project I couldn't get it to work, and used declare var $;. Not a clean/recommended solution, it doesnt recognise the JQuery variables, but I had no errors after using that (and had to for my automatic builds to succeed).

In my case, the reason the buttons got pushed up was because the view above them was a ScrollView, and it got collapsed with the buttons pushed up above the keyboard no matter what value of android:windowSoftInputMode I was setting.

I was able to avoid my bottom row of buttons getting pushed up by the soft keyboard by setting

android:isScrollContainer="false" 

on the ScrollView that sits above the buttons.

off of @IRadha's answer in vector drawable setting android:height="_dp" and setting the scale type to android:scaleType="center" sets the drawable to whatever size was set

Not really a reliable method, better of using JodaTime

  Calendar thatDay = Calendar.getInstance();
  thatDay.set(Calendar.DAY_OF_MONTH,25);
  thatDay.set(Calendar.MONTH,7); // 0-11 so 1 less
  thatDay.set(Calendar.YEAR, 1985);

  Calendar today = Calendar.getInstance();

  long diff = today.getTimeInMillis() - thatDay.getTimeInMillis(); //result in millis

Here's an approximation...

long days = diff / (24 * 60 * 60 * 1000);

To Parse the date from a string, you could use

  String strThatDay = "1985/08/25";
  SimpleDateFormat formatter = new SimpleDateFormat("yyyy/MM/dd");
  Date d = null;
  try {
   d = formatter.parse(strThatDay);//catch exception
  } catch (ParseException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } 


  Calendar thatDay = Calendar.getInstance();
  thatDay.setTime(d); //rest is the same....

Although, since you're sure of the date format... You Could also do Integer.parseInt() on it's Substrings to obtain their numeric values.

The default location for logon scripts is the netlogon share of a domain controller. On the server this is located:

%SystemRoot%'SYSVOL'sysvol''scripts

It can presumably be changes from this default but I've never met anyone that had a reason to.

To get list of domain controllers programatically see this article: http://www.microsoft.com/technet/scriptcenter/resources/qanda/dec04/hey1216.mspx

Simple Explanation, if you have mongo query Response something like below - and you want only highest value from Array-> "Date"

{
  "_id": "57ee5a708e117c754915a2a2",
  "TotalWishs": 3,
  "Events": [
    "57f805c866bf62f12edb8024"
  ],
  "wish": [
    "Cosmic Eldorado  Mountain Bikes, 26-inch (Grey/White)",
    "Asics Men's Gel-Nimbus 18 Black, Snow and Fiery Red Running Shoes - 10 UK/India (45 EU) (11 US)",
    "Suunto Digital Black Dial Unisex Watch - SS018734000"
  ],
  "Date": [
    "2017-02-13T00:00:00.000Z",
    "2017-03-05T00:00:00.000Z"
  ],
  "UserDetails": [
    {
      "createdAt": "2016-09-30T12:28:32.773Z",
      "jeenesFriends": [
        "57edf8a96ad8f6ff453a384a",
        "57ee516c8e117c754915a26b",
        "58a1644b6c91d2af783770b0",
        "57ef4631b97d81824cf54795"
      ],
      "userImage": "user_profile/Male.png",
      "email": "[email protected]",
      "fullName": "Roopak Kapoor"
    }
  ],

},

***Then you have add

Latest_Wish_CreatedDate: { $max: "$Date"},

somthing like below-

{ 
                $project : { _id: 1,
                             TotalWishs : 1 ,
                              wish:1 ,
                               Events:1, 
                               Wish_CreatedDate:1,
                               Latest_Wish_CreatedDate: { $max: "$Date"},
                            } 
            } 

And Final Query Response will be below

{
  "_id": "57ee5a708e117c754915a2a2",
  "TotalWishs": 3,
  "Events": [
    "57f805c866bf62f12edb8024"
  ],
  "wish": [
    "Cosmic Eldorado  Mountain Bikes, 26-inch (Grey/White)",
    "Asics Men's Gel-Nimbus 18 Black, Snow and Fiery Red Running Shoes - 10 UK/India (45 EU) (11 US)",
    "Suunto Digital Black Dial Unisex Watch - SS018734000"
  ],
  "Wish_CreatedDate": [
    "2017-03-05T00:00:00.000Z",
    "2017-02-13T00:00:00.000Z"
  ],
  "UserDetails": [
    {
      "createdAt": "2016-09-30T12:28:32.773Z",
      "jeenesFriends": [
        "57edf8a96ad8f6ff453a384a",
        "57ee516c8e117c754915a26b",
        "58a1644b6c91d2af783770b0",
        "57ef4631b97d81824cf54795"
      ],
      "userImage": "user_profile/Male.png",
      "email": "[email protected]",
      "fullName": "Roopak Kapoor"
    }
  ],
  "Latest_Wish_CreatedDate": "2017-03-05T00:00:00.000Z"
},

if (foo) is clear enough. Use it.

To add to answer given by Anil, In symfony3, you can use $this->getUser() to determine if the user is logged in, a simple condition like if(!$this->getUser()) {} will do.

If you look at the source code which is available in base controller, it does the exact same thing defined by Anil.

When the work I'm doing doesn't warrant using a library, I use these two functions:

function addClass( classname, element ) {
    var cn = element.className;
    //test for existance
    if( cn.indexOf( classname ) != -1 ) {
        return;
    }
    //add a space if the element already has class
    if( cn != '' ) {
        classname = ' '+classname;
    }
    element.className = cn+classname;
}

function removeClass( classname, element ) {
    var cn = element.className;
    var rxp = new RegExp( "\\s?\\b"+classname+"\\b", "g" );
    cn = cn.replace( rxp, '' );
    element.className = cn;
}

This uses git's internal difftool. Maybe a little work to do but straight forward.

#First checkout the branch you want to merge into
git checkout <branch_to_merge_into>
    
#Then checkout the file from the branch you want to merge from
git checkout <branch_to_merge_from> -- <file> 
    
#Then you have to unstage that file to be able to use difftool
git reset HEAD <file> 

#Now use difftool to chose which lines to keep. Click on the mergebutton in difftool
git difftool

#Save the file in difftool and you should be done.

You may use a controller in directive:

angular.module('app', [])
  .directive('appClick', function(){
     return {
       restrict: 'A',
       scope: true,
       template: '<button ng-click="click()">Click me</button> Clicked {{clicked}} times',
       controller: function($scope, $element){
         $scope.clicked = 0;
         $scope.click = function(){
           $scope.clicked++
         }
       }
     }
   });

Demo on plunkr

More about directives in Angular guide. And very helpfull for me was videos from official Angular blog post About those directives.

I disagree that .form-group should be within .col-*-n elements. In my experience, all the appropriate padding happens automatically when you use .form-group like .row within a form.

<div class="form-group">
    <div class="col-sm-12">
        <label for="user_login">Username</label>
        <input class="form-control" id="user_login" name="user[login]" required="true" size="30" type="text" />
    </div>
</div>

Check out this demo.

Altering the demo slightly by adding .form-horizontal to the form tag changes some of that padding.

<form action="#" method="post" class="form-horizontal">

Check out this demo.

When in doubt, inspect in Chrome or use Firebug in Firefox to figure out things like padding and margins. Using .row within the form fails in edsioufi's fiddle because .row uses negative left and right margins thereby drawing the horizontal bounds of the divs classed .row beyond the bounds of the containing fieldsets.
