You should delete A yourself in the destructor of B.

span.style.fontSize = "25px";

use this

(Adding to previous answers (hope that helps someone):)

Age is simpler but in case of string and with ignoring case:

• Just to verify the presence:

@fathers.any? { |father| father[:name].casecmp("john") == 0 } should work for any case in start or anywhere in the string i.e. for "John", "john" or "JoHn" and so on.

• To find first instance/index:

@fathers.find { |father| father[:name].casecmp("john") == 0 }

• To select all such indices:

@fathers.select { |father| father[:name].casecmp("john") == 0 }

If you use Gitlab than you might need to log in and accept Gitlab new terms, before you try to pull or push.

In case you are trying to search for a docker image from a docker registry, I guess the easiest way to check if a docker image is present is by using the Docker V2 REST API Tags list service

Example:-

curl $CURLOPTS -H "Authorization: Bearer $token" "https://hub.docker.com:4443/v2/your-repo-name/tags/list"

if the above result returns 200Ok with a list of image tags, then we know that image exists

{"name":"your-repo-name","tags":["1.0.0.1533677221","1.0.0.1533740305","1.0.0.1535659921","1.0.0.1535665433","latest"]}

else if you see something like

{"errors":[{"code":"NAME_UNKNOWN","message":"repository name not known to registry","detail":{"name":"your-repo-name"}}]} 

then you know for sure that image doesn't exist.

I found this solution useful in a NodeJS app. I use it just in desperate cases because it launches a timeout in order to wait for the full page load.

The second argument is the callback function which is going to be called once the response is ready.

phantom = require('phantom');

var fullLoad = function(anUrl, callbackDone) {
    phantom.create(function (ph) {
        ph.createPage(function (page) {
            page.open(anUrl, function (status) {
                if (status !== 'success') {
                    console.error("pahtom: error opening " + anUrl, status);
                    ph.exit();
                } else {
                    // timeOut
                    global.setTimeout(function () {
                        page.evaluate(function () {
                            return document.documentElement.innerHTML;
                        }, function (result) {
                            ph.exit(); // EXTREMLY IMPORTANT
                            callbackDone(result); // callback
                        });
                    }, 5000);
                }
            });
        });
    });
}

var callback = function(htmlBody) {
    // do smth with the htmlBody
}

fullLoad('your/url/', callback);

The operators || and && are called conditional operators, while | and & are called bitwise operators. They serve different purposes.

Conditional operators works only with expressions that statically evaluate to boolean on both left- and right-hand sides.

Bitwise operators works with any numeric operands.

If you want to perform a logical comparison, you should use conditional operators, since you will add some kind of type safety to your code.

So lets say you have Activity AB that controls Frag A and Fragment B. Inside Fragment A you need an interface that Activity AB can implement. In the sample android code, they have:

private Callbacks mCallbacks = sDummyCallbacks;

/*A callback interface that all activities containing this fragment must implement. This mechanism allows activities to be notified of item selections. */

public interface Callbacks {
/*Callback for when an item has been selected. */    
      public void onItemSelected(String id);
}

/*A dummy implementation of the {@link Callbacks} interface that does nothing. Used only when this fragment is not attached to an activity. */    
private static Callbacks sDummyCallbacks = new Callbacks() {
    @Override
    public void onItemSelected(String id) {
    }
};

The Callback interface is put inside one of your Fragments (let’s say Fragment A). I think the purpose of this Callbacks interface is like a nested class inside Frag A which any Activity can implement. So if Fragment A was a TV, the CallBacks is the TV Remote (interface) that allows Fragment A to be used by Activity AB. I may be wrong about the detail because I'm a noob but I did get my program to work perfectly on all screen sizes and this is what I used.

So inside Fragment A, we have: (I took this from Android’s Sample programs)

@Override
public void onListItemClick(ListView listView, View view, int position, long id) {
super.onListItemClick(listView, view, position, id);
// Notify the active callbacks interface (the activity, if the
// fragment is attached to one) that an item has been selected.
mCallbacks.onItemSelected(DummyContent.ITEMS.get(position).id);
//mCallbacks.onItemSelected( PUT YOUR SHIT HERE. int, String, etc.);
//mCallbacks.onItemSelected (Object);
}

And inside Activity AB we override the onItemSelected method:

public class AB extends FragmentActivity implements ItemListFragment.Callbacks {
//...
@Override
//public void onItemSelected (CATCH YOUR SHIT HERE) {
//public void onItemSelected (Object obj) {
    public void onItemSelected(String id) {
    //Pass Data to Fragment B. For example:
    Bundle arguments = new Bundle();
    arguments.putString(“FragmentB_package”, id);
    FragmentB fragment = new FragmentB();
    fragment.setArguments(arguments);
    getSupportFragmentManager().beginTransaction().replace(R.id.item_detail_container, fragment).commit();
    }

So inside Activity AB, you basically throwing everything into a Bundle and passing it to B. If u are not sure how to use a Bundle, look the class up.

I am basically going by the sample code that Android provided. The one with the DummyContent stuff. When you make a new Android Application Package, it's the one titled MasterDetailFlow.

My non pythonic approach would be using & suffix. That is:

python flashpolicyd.py &

To stop the script

killall flashpolicyd.py

also piping & suffix with disown would put the process under superparent (upper):

python flashpolicyd.pi & disown

Yes, this is new in PHP 5.3. It returns either the value of the test expression if it is evaluated as TRUE, or the alternative value if it is evaluated as FALSE.

I had a very similar problem, I had an array ready to be posted. in my post function I had this:

json = JSON.stringfy(json);

the detail here is that I'm using blade inside laravel to build a three view form, so I can go back and forward, I have in between every back and forward button validations and when I go back in the form without reloading the page my json get filled by backslashes. I console.log(json) in every validation and realized that the json was treated as a string instead of an object.

In conclution i shouldn't have assinged json = JSON.stringfy(json) instead i assigned it to another variable.

var aux = JSON.stringfy(json);

This way i keep json as an object, and not a string.

How about programmatically modifying the size attribute on the input?

Semantically (imo), this solution is better than the accepted solution because it still uses input fields for user input but it does introduce a little bit of jQuery. Soundcloud does something similar to this for their tagging.

<input size="1" />

$('input').on('keydown', function(evt) {
    var $this = $(this),
        size = parseInt($this.attr('size'), 10),
        isValidKey = (evt.which >= 65 && evt.which <= 90) || // a-zA-Z
                     (evt.which >= 48 && evt.which <= 57) || // 0-9
                     evt.which === 32;

    if ( evt.which === 8 && size > 0 ) {
        // backspace
        $this.attr('size', size - 1);
    } else if ( isValidKey ) {
        // all other keystrokes
        $this.attr('size', size + 1);
    }
});

I have changed to your code with little modification will works well. Here is the code:

butangDonload.php

<?php
$file = "logo_ldg.png"; //Let say If I put the file name Bang.png
echo "<a href='download1.php?nama=".$file."'>download</a> ";
?>

download.php

<?php
$name= $_GET['nama'];

    header('Content-Description: File Transfer');
    header('Content-Type: application/force-download');
    header("Content-Disposition: attachment; filename=\"" . basename($name) . "\";");
    header('Content-Transfer-Encoding: binary');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($name));
    ob_clean();
    flush();
    readfile("your_file_path/".$name); //showing the path to the server where the file is to be download
    exit;
?>

Here you need to show the path from where the file to be download. i.e. will just give the file name but need to give the file path for reading that file. So, it should be replaced by I have tested by using your code and modifying also will works.

I want to say something about the "G" status,

G: Changes on the repo were automatically merged into the working copy

I think the above definition is not cleary, it can generate a little confusion, because all files are automatically merged in to working copy, the correct one should be:

U = item (U)pdated to repository version

G = item’s local changes mer(G)ed with repository

C = item’s local changes (C)onflicted with repository

D = item (D)eleted from working copy

A = item (A)dded to working copy

You can also try react-native-extended-stylesheet that supports percentage for single-orientation apps:

import EStyleSheet from 'react-native-extended-stylesheet';

const styles = EStyleSheet.create({
  column: {
    width: '80%',
    height: '50%',
    marginLeft: '10%'
  }
});

Signed variables, such as signed integers will allow you to represent numbers both in the positive and negative ranges.

Unsigned variables, such as unsigned integers, will only allow you to represent numbers in the positive and zero.

Unsigned and signed variables of the same type (such as int and byte) both have the same range (range of 65,536 and 256 numbers, respectively), but unsigned can represent a larger magnitude number than the corresponding signed variable.

For example, an unsigned byte can represent values from 0 to 255, while signed byte can represent -128 to 127.

Wikipedia page on Signed number representations explains the difference in the representation at the bit level, and the Integer (computer science) page provides a table of ranges for each signed/unsigned integer type.

I had a similar issue; upgrading to Apache HTTPClient 4.5.3 fixed it.

If the function you called returns null, it means your phone number is not registered in your contact list.

If instead of the phone number you just need an unique number, you may use the sim card's serial number:

    TelephonyManager telemamanger = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
    String getSimSerialNumber = telemamanger.getSimSerialNumber();  

This article describes how to render text in OpenGL using various techniques.

With only using opengl, there are several ways:

• using glBitmap
• using textures
• using display lists

You will usually want to use forward declaration in a classes header file when you want to use the other type (class) as a member of the class. You can not use the forward-declared classes methods in the header file because C++ does not know the definition of that class at that point yet. That's logic you have to move into the .cpp-files, but if you are using template-functions you should reduce them to only the part that uses the template and move that function into the header.

Very simple, you close it :)

var myWebSocket = new WebSocket("ws://example.org"); 
myWebSocket.send("Hello Web Sockets!"); 
myWebSocket.close();

Did you check also the following site And check the introduction article of Opera

visibility:hidden is the proper syntax, but another way to 'hide' the table is with display:none or dynamically with JQuery:

$('#myTable').hide()

It's a shortening for this:

notification.defaults = notification.defaults | Notification.DEFAULT_SOUND;

And | is a bit-wise OR.

For me i install java version 8 and just select the java version in "JDK location":

Please follow the below steps :

 1) Locate php.ini in your apache bin folder, I.e Apache/bin/php.ini
 2) Remove the ; from the beginning of extension=php_soap.dll
 3) Restart your Apache server (by using : 
    # /etc/init.d/apache2 restart OR 
    $ sudo /etc/init.d/apache2 restart OR 
    $ sudo service apache2 restart)
 4) Look up your phpinfo();

This answer is like rodrigob's except without the BOOST_FOREACH. You can use c++'s range based for instead.

#include <map>
#include <boost/range/adaptor/map.hpp>
#include <iostream>

template <typename K, typename V>
void printKeys(std::map<K,V> map){
     for(auto key : map | boost::adaptors::map_keys){
          std::cout << key << std::endl;
     }
}

Follow the simple steps to rename your app name and Package name in case you have not made any custom changes in android folder(ie. scenario where u just initialized the project)

1. Simply change the name in the package.json file as you need and save it.
2. Remove the folder named android
3. run the command react-native upgrade

Note:As ivoteje50 mentioned in comment,Don't remove the android folder if you have already followed the official instructions to generate a keystore, since it will remove the keystore and you cannot sign a new app again.

You should use :first-child instead of :first:

Sounds like you're wanting to iterate through them. You can do this using .each().

Example:

$('td:first-child').each(function() {
    console.log($(this).text());
});

Result:

nonono
nonono2
nonono3

Alernatively if you're not wanting to iterate:

$('td:first-child').css('background', '#000');

Necromancing:

It's relativiely simple to emulate a COUNT DISTINCT over PARTITION BY with MAX via DENSE_RANK:

;WITH baseTable AS
(
    SELECT 'RM1' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM1' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR2' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR2' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR3' AS ADR
    UNION ALL SELECT 'RM3' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM2' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM3' AS RM, 'ADR1' AS ADR
    UNION ALL SELECT 'RM3' AS RM, 'ADR2' AS ADR
)
,CTE AS
(
    SELECT RM, ADR, DENSE_RANK() OVER(PARTITION BY RM ORDER BY ADR) AS dr 
    FROM baseTable
)
SELECT
     RM
    ,ADR

    ,COUNT(CTE.ADR) OVER (PARTITION BY CTE.RM ORDER BY ADR) AS cnt1 
    ,COUNT(CTE.ADR) OVER (PARTITION BY CTE.RM) AS cnt2 
    -- Not supported
    --,COUNT(DISTINCT CTE.ADR) OVER (PARTITION BY CTE.RM ORDER BY CTE.ADR) AS cntDist
    ,MAX(CTE.dr) OVER (PARTITION BY CTE.RM ORDER BY CTE.RM) AS cntDistEmu 
FROM CTE

Note:
This assumes the fields in question are NON-nullable fields.
If there is one or more NULL-entries in the fields, you need to subtract 1.

Example:

DECLARE @Str NVARCHAR(MAX) = N'
            foo   bar
        Foo           Bar        

'

PRINT '[' + @Str + ']'

DECLARE @StrPrv NVARCHAR(MAX) = N''

WHILE ((@StrPrv <> @Str) AND (@Str IS NOT NULL)) BEGIN
    SET @StrPrv = @Str

    -- Beginning
    IF EXISTS (SELECT 1 WHERE @Str LIKE '[' + CHAR(13) + CHAR(10) + CHAR(9) + ']%')
        SET @Str = LTRIM(RIGHT(@Str, LEN(@Str) - 1))

    -- Ending
    IF EXISTS (SELECT 1 WHERE @Str LIKE '%[' + CHAR(13) + CHAR(10) + CHAR(9) + ']')
        SET @Str = RTRIM(LEFT(@Str, LEN(@Str) - 1))
END

PRINT '[' + @Str + ']'

Result

[
            foo   bar
        Foo           Bar        

]
[foo   bar
        Foo           Bar]

You can use a script called tablespaces.sh inside this helpful bundle: http://dba-tips.blogspot.com/2014/02/oracle-database-administration-scripts.html

To expand on cristobalito's answer:

I assume you're talking about on the command-line - if it's in a script, then a new-line >acts as a command delimiter.

On the command line, use a semi-colon ';'

For example:

Sign a PowerShell script on the command-line. No line breaks.

powershell -Command "&{$cert=Get-ChildItem –Path cert:\CurrentUser\my -codeSigningCert ; Set-AuthenticodeSignature -filepath Z:\test.ps1 -Cert $cert}

There is also a flag CV_VERSION which will print out the full version of opencv

//detailed code for the problem
//suppose we have a enumerable collection 'collection'
var lastIndexOfCollection=collection.Count-1 ;
var nthIndexFromLast= lastIndexOfCollection- N;

var desiredCollection=collection.GetRange(nthIndexFromLast, N);
---------------------------------------------------------------------

// use this one liner
var desiredCollection=collection.GetRange((collection.Count-(1+N)), N);

thisReader.GetString(int columnIndex)

This function extends the function from Gaten's answer a bit in order to get the element back:

$.fn.delayKeyup = function(callback, ms){
    var timer = 0;
    var el = $(this);
    $(this).keyup(function(){                   
    clearTimeout (timer);
    timer = setTimeout(function(){
        callback(el)
        }, ms);
    });
    return $(this);
};

$('#input').delayKeyup(function(el){
    //alert(el.val());
    // Here I need the input element (value for ajax call) for further process
},1000);

Backbone is...

...a very small library of components which you can use to help organise your code. It comes packaged as a single JavaScript file. Excluding comments, it has less than 1000 lines of actual JavaScript. It's sensibly written and you can read the whole thing in a couple of hours.

It's a front-end library, you include it in your web page with a script tag. It only affects the browser, and says little about your server, except that it should ideally expose a restful API.

If you have an API, Backbone has a few helpful features that will help you talk to it, but you can use Backbone to add interactivity to any static HTML page.

Backbone is for...

...adding structure to JavaScript.

Because JavaScript doesn't enforce any particular patterns, JavaScript applications can become very messy very quickly. Anyone who has built something beyond trivial in JavaScript will have likely run up against questions such as:

1. Where will I store my data?
2. Where will I put my functions?
3. How will I wire my functions together, so that they are called in a sensible way and don't turn to spaghetti?
4. How can I make this code maintainable by different developers?

Backbone seeks to answer these questions by giving you:

• Models and Collections to help you represent data and collections of data.
• Views, to help you update your DOM when your data changes.
• An event system so that components can listen to each other. This keeps your components de-coupled and prevents spaghettification.
• A minimal set of sensible conventions, so developers can work together on the same codebase.

We call this an MV* pattern. Models, Views and optional extras.

Backbone is light

Despite initial appearances, Backbone is fantastically light, it hardly does anything at all. What it does do is very helpful.

It gives you a set of little objects which you can create, and which can emit events and listen to each other. You might create a little object to represent a comment for example, and then a little commentView object to represent the display of the comment in a particular place in the browser.

You can tell the commentView to listen to the comment and redraw itself when the comment changes. Even if you have the same comment displayed in several places on your page all these views can listen to the same comment model and stay in sync.

This way of composing code helps to keep you from getting tangled even if your codebase becomes very large with many interactions.

Models

When starting out, it's common to store your data either in a global variable, or in the DOM as data attributes. Both of these have issues. Global variables can conflict with each other, and are generally bad form. Data attributes stored in the DOM can only be strings, you will have to parse them in and out again. It's difficult to store things like arrays, dates or objects, and to parse your data in a structured form.

Data attributes look like this:

<p data-username="derek" data-age="42"></p>

Backbone solves this by providing a Model object to represent your data and associated methods. Say you have a todo list, you would have a model representing each item on that list.

When your model is updated, it fires an event. You might have a view tied to that particular object. The view listens for model change events and re-renders itself.

Views

Backbone provides you with View objects that talk to the DOM. All functions that manipulate the DOM or listen for DOM events go here.

A View typically implements a render function which redraws the whole view, or possibly part of the view. There's no obligation to implement a render function, but it's a common convention.

Each view is bound to a particular part of the DOM, so you might have a searchFormView, that only listens to the search form, and a shoppingCartView, that only displays the shopping cart.

Views are typically also bound to specific Models or Collections. When the Model updates, it fires an event which the view listens to. The view might them call render to redraw itself.

Likewise, when you type into a form, your view can update a model object. Every other view listening to that model will then call its own render function.

This gives us a clean separation of concerns that keeps our code neat and tidy.

The render function

You can implement your render function in any way you see fit. You might just put some jQuery in here to update the DOM manually.

You might also compile a template and use that. A template is just a string with insertion points. You pass it to a compile function along with a JSON object and get back a compiled string which you can insert into your DOM.

Collections

You also have access to collections which store lists of models, so a todoCollection would be a list of todo models. When a collection gains or loses a model, changes its order, or a model in a collection updates, the whole collection fires an event.

A view can listen to a collection and update itself whenever the collection updates.

You could add sort and filter methods to your collection, and make it sort itself automatically for example.

And Events to Tie It All Together

As much as possible, application components are decoupled from each other. They communicate using events, so a shoppingCartView might listenTo a shoppingCart collection, and redraw itself when the cart is added to.

shoppingCartView.listenTo(shoppingCart, "add", shoppingCartView.render);

Of course, other objects might also be listening to the shoppingCart as well, and might do other things like update a total, or save the state in local storage.

• Views listen to Models and render when the model changes.
• Views listen to collections and render a list (or a grid, or a map, etc.) when an item in the collection changes.
• Models listen to Views so they can change state, perhaps when a form is edited.

Decoupling your objects like this and communicating using events means that you'll never get tangled in knots, and adding new components and behaviour is easy. Your new components just have to listen to the other objects already in the system.

Conventions

Code written for Backbone follows a loose set of conventions. DOM code belongs in a View. Collection code belongs in a Collection. Business logic goes in a model. Another developer picking up your codebase will be able to hit the ground running.

To sum up

Backbone is a lightweight library that lends structure to your code. Components are decoupled and communicate via events so you won't end up in a mess. You can extend your codebase easily, simply by creating a new object and having it listen to your existing objects appropriately. Your code will be cleaner, nicer, and more maintainable.

My little book

I liked Backbone so much that I wrote a little intro book about it. You can read it online here: http://nicholasjohnson.com/backbone-book/

I also broke the material down into a short online course, which you can find here: http://www.forwardadvance.com/course/backbone. You can complete the course in about a day.

Check the solution below for your question:

int total = (int) Math.ceil(157/32);

Here you should multiply Numerator with 1.0, then it will give your answer.

int total = (int) Math.ceil(157*1.0/32);

You could have an array that starts out with 10 elements. Read input character by character. If it goes over, realloc another 5 more. Not the best, but then you can free the other space later.

It appears that SQL Server 2008 R2 can be downloaded with or without the management tools. I honestly have NO IDEA why someone would not want the management tools. But either way, the options are here:

http://www.microsoft.com/sqlserver/en/us/editions/express.aspx

and the one for 64 bit WITH the management tools (management studio) is here:

http://www.microsoft.com/sqlserver/en/us/editions/express.aspx

From the first link I presented, the 3rd and 4th include the management studio for 32 and 64 bit respectively.

When the game starts:

long tStart = System.currentTimeMillis();

When the game ends:

long tEnd = System.currentTimeMillis();
long tDelta = tEnd - tStart;
double elapsedSeconds = tDelta / 1000.0;

The request is printed in a request.txt with details

$ch = curl_init();
$f = fopen('request.txt', 'w');
curl_setopt_array($ch, array(
CURLOPT_URL            => $url, 
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_FOLLOWLOCATION => 1,
CURLOPT_VERBOSE        => 1,
CURLOPT_STDERR         => $f,
));
$response = curl_exec($ch);
fclose($f);
curl_close($ch);

You can also use curl_getinfo() function.

Run your script with .

. myscript.sh

This will run the script in the current shell environment.

export governs which variables will be available to new processes, so if you say

FOO=1
export BAR=2
./runScript.sh

then $BAR will be available in the environment of runScript.sh, but $FOO will not.

Do you have _timestamp enabled in your doc mapping?

{
    "doctype": {
        "_timestamp": {
            "enabled": "true",
            "store": "yes"
        },
        "properties": {
            ...
        }
    }
}

You can check your mapping here:

http://localhost:9200/_all/_mapping

If so I think this might work to get most recent:

{
  "query": {
    "match_all": {}
  },
  "size": 1,
  "sort": [
    {
      "_timestamp": {
        "order": "desc"
      }
    }
  ]
}

Convert your image file to Base64 string with a tool like this and then replace the YourBase64StringHere placeholder in the below snippet with your string and put the line in your HTML head section:

<link href="data:image/x-icon;base64,YourBase64StringHere" rel="icon" type="image/x-icon" />

This will work 100% in browsers.

Just thought I would post something that I found quite useful and could be possible for someone who experiences similar needs.

The following method was a method I wrote for my JavaFX application to avoid having to cast and also avoid writing if object x instance of object b statements every time the controller was returned.

public <U> Optional<U> getController(Class<U> castKlazz){
    try {
        return Optional.of(fxmlLoader.<U>getController());
    }catch (Exception e){
        e.printStackTrace();
    }
    return Optional.empty();
}

The method declaration for obtaining the controller was

public <T> T getController()

By using type U passed into my method via the class object, it could be forwarded to the method get controller to tell it what type of object to return. An optional object is returned in case the wrong class is supplied and an exception occurs in which case an empty optional will be returned which we can check for.

This is what the final call to the method looked like (if present of the optional object returned takes a Consumer

getController(LoadController.class).ifPresent(controller->controller.onNotifyComplete());

If your button is default "button" make sure you explicity set the type attribute, otherwise the WebForm will treat it as submit by default.

if you use js do like this

<form method="POST">
   <button name="data"  type="button" id="btnData" onclick="getData()">Click</button>
</form> 

**If you use jquery use like this**


<form method="POST">
   <button name="data"  type="button" id="btnData">Click</button>
</form>




$('#btnData').click(function(e){
   e.preventDefault();
   // Code goes here
getData(); // your onclick function call here

});

If the other solutions here do not work, make sure you are not in 'offline' mode. If enabled, android will not download the required files and you will get this error.

If you're using AppCompat, declare your activity in AndroidManifest.xml as follows:

<activity
    android:name=".SomeActivity"
    ...
    android:theme="@style/Theme.AppCompat.Light.NoActionBar" />

I think the best and simplest solution is (KISS):

double i = 348842;
double i2 = i/60000;
float k = (float) Math.round(i2 * 100) / 100;

Just To mention, in CSS 3

:after

should be used like this

::after

From https://developer.mozilla.org/de/docs/Web/CSS/::after :

The ::after notation was introduced in CSS 3 in order to establish a discrimination between pseudo-classes and pseudo-elements. Browsers also accept the notation :after introduced in CSS 2.

So it should be:

li { display: inline; list-style-type: none; }
li::after { content: ", "; }
li:last-child::before { content: "and "; }
li:last-child::after { content: "."; }

You can do it in one line of code:

Log.d("intent URI", intent.toUri(0));

It outputs something like:

"#Intent;action=android.intent.action.MAIN;category=android.intent.category.LAUNCHER;launchFlags=0x10a00000;component=com.mydomain.myapp/.StartActivity;sourceBounds=12%20870%20276%201167; l.profile=0; end"

At the end of this string (the part that I bolded) you can find the list of extras (only one extra in this example).

This is according to the toUri documentation: "The URI contains the Intent's data as the base URI, with an additional fragment describing the action, categories, type, flags, package, component, and extras."

If you just want the response as text and don't want to convert it into JSON, use https://developer.mozilla.org/en-US/docs/Web/API/Body/text and then then it to get the actual result of the promise:

fetch('city-market.md')
  .then(function(response) {
    response.text().then((s) => console.log(s));
  });

or

fetch('city-market.md')
  .then(function(response) {
    return response.text();
  })
  .then(function(myText) {
    console.log(myText);
  });

Another option is to use a ToggleButton with null background and a custom button.

Bellow an example that includes a selector to the text color as well.

<ToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:button="@drawable/toggle_selector"
    android:background="@null"
    android:paddingLeft="10dp"
    android:layout_centerHorizontal="true"
    android:gravity="center"
    android:textColor="@drawable/toggle_text"
    android:textOn="My on state"
    android:textOff="My off state" />

toggle_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:state_checked="true"
        android:drawable="@drawable/state_on" />

    <item
        android:drawable="@drawable/state_off" />

</selector>

toggle_text.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:state_checked="true"
        android:color="@color/app_color" />

    <item
        android:color="@android:color/darker_gray" />

</selector>

In Javascript the idea of boolean is fairly ambiguous. Consider this:

 var bool = 0 
 if(bool){..} //evaluates to false

 if(//uninitialized var) //evaluates to false

So when you're using an if statement, (or any other control statement), one does not have to use a "boolean" type var. Therefore, in my opinion, the "=== true" part of your statement is unnecessary if you know it is a boolean, but absolutely necessary if your value is an ambiguous "truthy" var. More on booleans in javscript can be found here.

I've resorted to

df[ (df[column_name].notnull()) & (df[column_name]!=u'') ].index

lately. That gets both null and empty-string cells in one go.

You can also use chmod 777 *

This will give permissions to all files currently in the folder and files added in the future without giving permissions to the directory itself.

NOTE: This should be done in the folder where the files are located. For me it was an images that had an issue so I went to my images folder and did this.

- (void)performAndWait:(void (^)(dispatch_semaphore_t semaphore))perform;
{
  NSParameterAssert(perform);
  dispatch_semaphore_t semaphore = dispatch_semaphore_create(0);
  perform(semaphore);
  dispatch_semaphore_wait(semaphore, DISPATCH_TIME_FOREVER);
  dispatch_release(semaphore);
}

Example usage:

[self performAndWait:^(dispatch_semaphore_t semaphore) {
  [self someLongOperationWithSuccess:^{
    dispatch_semaphore_signal(semaphore);
  }];
}];

Check both my JavaScript and JQuery code :

JavaScript:

if (!document.getElementById('MyElementId')){
    alert('Does not exist!');
}

JQuery:

if (!$("#MyElementId").length){
    alert('Does not exist!');
}

As @Antonijn stated, you need to execute getTitle method, by adding parentheses:

 string t = obj.getTitle();

But I want to add, that you are doing Java programming in C#. There is concept of properties (pair of get and set methods), which should be used in such cases:

public class Pin
{
    private string _title;

    // you don't need to define empty constructor
    // public Pin() { }

    public string Title 
    {
        get { return _title; }
        set { _title = value; }
    }  
}

And even more, in this case you can ask compiler not only for get and set methods generation, but also for back storage generation, via auto-impelemented property usage:

public class Pin
{
    public string Title { get; set; }
}

And now you don't need to execute method, because properties used like fields:

foreach (Pin obj in ClassListPin.pins)
{
     string t = obj.Title;
}

On the side note, here is how the various plyr functions correspond to the base *apply functions (from the intro to plyr document from the plyr webpage http://had.co.nz/plyr/)

Base function   Input   Output   plyr function 
---------------------------------------
aggregate        d       d       ddply + colwise 
apply            a       a/l     aaply / alply 
by               d       l       dlply 
lapply           l       l       llply  
mapply           a       a/l     maply / mlply 
replicate        r       a/l     raply / rlply 
sapply           l       a       laply 

One of the goals of plyr is to provide consistent naming conventions for each of the functions, encoding the input and output data types in the function name. It also provides consistency in output, in that output from dlply() is easily passable to ldply() to produce useful output, etc.

Conceptually, learning plyr is no more difficult than understanding the base *apply functions.

plyr and reshape functions have replaced almost all of these functions in my every day use. But, also from the Intro to Plyr document:

Related functions tapply and sweep have no corresponding function in plyr, and remain useful. merge is useful for combining summaries with the original data.

My handmade solution:

In the layout:

<LinearLayout
        android:orientation="horizontal"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/dots"
        />

And in the Activity

private final static int NUM_PAGES = 5;
private ViewPager mViewPager;
private List<ImageView> dots;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // ...
    addDots();
}

public void addDots() {
    dots = new ArrayList<>();
    LinearLayout dotsLayout = (LinearLayout)findViewById(R.id.dots);

    for(int i = 0; i < NUM_PAGES; i++) {
        ImageView dot = new ImageView(this);
        dot.setImageDrawable(getResources().getDrawable(R.drawable.pager_dot_not_selected));

        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.WRAP_CONTENT,
                LinearLayout.LayoutParams.WRAP_CONTENT
        );
        dotsLayout.addView(dot, params);

        dots.add(dot);
    }

    mViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
        }

        @Override
        public void onPageSelected(int position) {
            selectDot(position);
        }

        @Override
        public void onPageScrollStateChanged(int state) {
        }
    });
}

public void selectDot(int idx) {
    Resources res = getResources();
    for(int i = 0; i < NUM_PAGES; i++) {
        int drawableId = (i==idx)?(R.drawable.pager_dot_selected):(R.drawable.pager_dot_not_selected);
        Drawable drawable = res.getDrawable(drawableId);
        dots.get(i).setImageDrawable(drawable);
    }
}

Necroing this question but there's an explanation that no-one seems to have considered.

STATISTICS - Statistics are not available or misleading

If all of the following are true:

1. The columns feedid and feedDate are likely to be highly correlated (e.g. a feed id is more specific than a feed date and the date parameter is redundant information).
2. There is no index with both columns as sequential columns.
3. There are no manually created statistics covering both these columns.

Then sql server may be incorrectly assuming that the columns are uncorrelated, leading to lower than expected cardinality estimates for applying both restrictions and a poor execution plan being selected. The fix in this case would be to create a statistics object linking the two columns, which is not an expensive operation.

The accepted answer works great if you just want to use a different context in your partial. However, it doesn't let you reference any of the parent context. To pass in multiple arguments, you need to write your own helper. Here's a working helper for Handlebars 2.0.0 (the other answer works for versions <2.0.0):

Handlebars.registerHelper('renderPartial', function(partialName, options) {
    if (!partialName) {
        console.error('No partial name given.');
        return '';
    }
    var partial = Handlebars.partials[partialName];
    if (!partial) {
        console.error('Couldnt find the compiled partial: ' + partialName);
        return '';
    }
    return new Handlebars.SafeString( partial(options.hash) );
});

Then in your template, you can do something like:

{{renderPartial 'myPartialName' foo=this bar=../bar}}

And in your partial, you'll be able to access those values as context like:

<div id={{bar.id}}>{{foo}}</div>

Use SET STATISTICS TIME ON

above your query.

Below near result tab you can see a message tab. There you can see the time.

The application has to be both compiled and linked with -g option. I.e. you need to put -g in both CPPFLAGS and LDFLAGS.

In swift 2.0

var stringMe="Something In this.World"
var needle="."
if let idx = stringMe.characters.indexOf(needle) {
    let pos=stringMe.substringFromIndex(idx)
    print("Found \(needle) at position \(pos)")
}
else {
    print("Not found")
}

Try this instead simple request code
https://www.learn2crack.com/2015/10/android-marshmallow-permissions.html

public static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;

private  boolean checkAndRequestPermissions() {
    int camera = ContextCompat.checkSelfPermission(this, android.Manifest.permission.CAMERA);
    int storage = ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
    int loc = ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION);
    int loc2 = ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION);
    List<String> listPermissionsNeeded = new ArrayList<>();

    if (camera != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(android.Manifest.permission.CAMERA);
    }
    if (storage != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(android.Manifest.permission.WRITE_EXTERNAL_STORAGE);
    }
    if (loc2 != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(android.Manifest.permission.ACCESS_FINE_LOCATION);
    }
    if (loc != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(android.Manifest.permission.ACCESS_COARSE_LOCATION);
    }
    if (!listPermissionsNeeded.isEmpty())
    {
        ActivityCompat.requestPermissions(this,listPermissionsNeeded.toArray
                (new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);
        return false;
    }
    return true;
}

Workaround for adding a device to an existing (automatically or manually created) provisioning profile (tested in Xcode 8.2.1):

1. Add the device in the developer portal.
2. Only when using a manually created profile: add the device to the profile.
3. In Xcode, go to Xcode > Preferences > "Accounts" tab > select your Apple ID (left pane) > double click on your Team Name.
4. Locate the existing provisioning profile. (automatically created profiles will begin with 'iOS Team Provisioning Profile' or 'XC iOS' or similar.
5. Right click on the profile.
6. Choose 'Move to Trash'.
7. The profile will disappear. A new profile with the same name might appear again, that is OK.

Xcode should now be aware of the newly added device.

With Android 8.0 using Custom Fonts in Application became easy with downloadable fonts. We can add fonts directly to the res/font/ folder in the project folder, and in doing so, the fonts become automatically available in Android Studio.

Now set fontFamily attribute to list of fonts or click on more and select font of your choice. This will add tools:fontFamily="@font/your_font_file" line to your TextView.

This will Automatically generate few files.

1. In values folder it will create fonts_certs.xml.

2. In Manifest it will add this lines:

  <meta-data
            android:name="preloaded_fonts"
            android:resource="@array/preloaded_fonts" /> 

3. preloaded_fonts.xml

<resources>
    <array name="preloaded_fonts" translatable="false">
        <item>@font/open_sans_regular</item>
        <item>@font/open_sans_semibold</item>
    </array>
</resources>

You have empty $entry_database variable. As you see in error: ListEmail, Title FROM WHERE ID bewteen FROM and WHERE should be name of table. Proper syntax of SELECT:

SELECT columns FROM table [optional things as WHERE/ORDER/GROUP/JOIN etc]

which in your way should become:

SELECT ID, ListStID, ListEmail, Title FROM some_table_you_got WHERE ID = '4'

The default dbpath for mongodb is /data/db.

There is no default config file, so you will either need to specify this when starting mongod with:

 mongod --config /etc/mongodb.conf

.. or use a packaged install of MongoDB (such as for Redhat or Debian/Ubuntu) which will include a config file path in the service definition.

Note: to check the dbpath and command-line options for a running mongod, connect via the mongo shell and run:

db.serverCmdLineOpts()

In particular, if a custom dbpath is set it will be the value of:

db.serverCmdLineOpts().parsed.dbpath           // MongoDB 2.4 and older
db.serverCmdLineOpts().parsed.storage.dbPath   // MongoDB 2.6+

The OS failed to install the required update Windows8.1-KB2999226-x64.msu. However I tried to find the particular update from -

C:\ProgramData\Package Cache\469A82B09E217DDCF849181A586DF1C97C0C5C85\packages\Patch\amd64\Windows8.1-KB2999226-x64.msu.

I couldn't find it there so I installed the kb2999226 update from here (Windows 10 Universal C runtime)

Then I installed the update according to my OS and after that It was working fine.

In the .NET world, I recommend the HTML Agility Pack. Not near as simple as some of the above options (like HTMLSQL), but it's very flexible. It lets you maniuplate poorly formed HTML as if it were well formed XML, so you can use XPATH or just itereate over nodes.

Owen has a good answer. If you want just the key, and you are working with an array this might also be useful.

foreach(array_keys($array) as $key) {
//  do stuff
}

The constructor is called only once, so you can safely do what you want, however the disadvantage of calling methods from within the constructor, rather than directly, is that you don't get direct feedback if the method fails. This gets more difficult the more methods you call.

One solution is to provide methods that you can call to query the 'health' of the object once it's been constructed. For example the method isConfigOK() can be used to see if the config read operation was OK.

Another solution is to throw exceptions in the constructor upon failure, but it really depends on how 'fatal' these failures are.

class A
{
    Map <String,String> config = null;
    public A()
    {
        readConfig();
    }

    protected boolean readConfig()
    {
        ...
    }

    public boolean isConfigOK()
    {
        // Check config here
        return true;
    }
};

use this method

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT)
    {
        Toast.makeText(getActivity(),"PORTRAIT",Toast.LENGTH_LONG).show();
       //add your code what you want to do when screen on PORTRAIT MODE
    }
    else if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE)
    {
        Toast.makeText(getActivity(),"LANDSCAPE",Toast.LENGTH_LONG).show();
        //add your code what you want to do when screen on LANDSCAPE MODE
   }
}

And Do not forget to Add this in your Androidmainfest.xml

android:configChanges="orientation|screenSize"

like this

<activity android:name=".MainActivity"
          android:theme="@style/Theme.AppCompat.NoActionBar"
          android:configChanges="orientation|screenSize">

    </activity>

To Save your bitmap in sdcard use the following code

Store Image

private void storeImage(Bitmap image) {
    File pictureFile = getOutputMediaFile();
    if (pictureFile == null) {
        Log.d(TAG,
                "Error creating media file, check storage permissions: ");// e.getMessage());
        return;
    } 
    try {
        FileOutputStream fos = new FileOutputStream(pictureFile);
        image.compress(Bitmap.CompressFormat.PNG, 90, fos);
        fos.close();
    } catch (FileNotFoundException e) {
        Log.d(TAG, "File not found: " + e.getMessage());
    } catch (IOException e) {
        Log.d(TAG, "Error accessing file: " + e.getMessage());
    }  
}

To Get the Path for Image Storage

/** Create a File for saving an image or video */
private  File getOutputMediaFile(){
    // To be safe, you should check that the SDCard is mounted
    // using Environment.getExternalStorageState() before doing this. 
    File mediaStorageDir = new File(Environment.getExternalStorageDirectory()
            + "/Android/data/"
            + getApplicationContext().getPackageName()
            + "/Files"); 

    // This location works best if you want the created images to be shared
    // between applications and persist after your app has been uninstalled.

    // Create the storage directory if it does not exist
    if (! mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){
            return null;
        }
    } 
    // Create a media file name
    String timeStamp = new SimpleDateFormat("ddMMyyyy_HHmm").format(new Date());
    File mediaFile;
        String mImageName="MI_"+ timeStamp +".jpg";
        mediaFile = new File(mediaStorageDir.getPath() + File.separator + mImageName);  
    return mediaFile;
} 

EDIT From Your comments i have edited the onclick view in this the button1 and button2 functions will be executed separately.

public onClick(View v){

switch(v.getId()){
case R.id.button1:
//Your button 1 function
break;
case R.id. button2:
//Your button 2 function
break;

For utl_file.open(location,filename,mode) , we need to give directory name for location but not path. For Example:DATA_FILE_DIR , this is the directory name and check out the directory path for that particular directory name.

A function is, at a basic level, a block of code that can executed, not when written, but when called. So let's say I have the following piece of code, which is a simple multiplication function:

def multiply(x,y):
    return x * y

So if I called the function with multiply(2,3), it would return the value 6. If I modified the function so it looks like this:

def multiply(x,y):
    print(x*y)
    return x*y

...then the output is as you would expect, the number 6 printed. However, the difference between these two statements is that print merely shows something on the console, but return "gives something back" to whatever called it, which is often a variable. The variable is then assigned the value of the return statement in the function that it called. Here is an example in the python shell:

>>> def multiply(x,y):
        return x*y

>>> multiply(2,3) #no variable assignment
6
>>> answer = multiply(2,3) #answer = whatever the function returns
>>> answer
6

So now the function has returned the result of calling the function to the place where it was called from, which is a variable called 'answer' in this case.

This does much more than simply printing the result, because you can then access it again. Here is an example of the function using return statements:

>>> x = int(input("Enter a number: "))
Enter a number: 5
>>> y = int(input("Enter another number: "))
Enter another number: 6
>>> answer = multiply(x,y)
>>> print("Your answer is {}".format(answer)
Your answer is 30

So it basically stores the result of calling a function in a variable.

You can Try using :- git ls-files -s

You can't, but you can use BETWEEN

SELECT job FROM mytable WHERE id BETWEEN 10 AND 15

Note that BETWEEN is inclusive, and will include items with both id 10 and 15.

If you do not want inclusion, you'll have to fall back to using the > and < operators.

SELECT job FROM mytable WHERE id > 10 AND id < 15

My personal preference is to put it in ~/opt/local/android-sdk-mac or /Developer/android-sdk-mac the latter being where Xcode and all the Apple Dev tools are held.

for those like me that had queries time out. I made the below to use limits and anything else by a specific group.

DELIMITER $$
CREATE PROCEDURE count_limit200()
BEGIN
    DECLARE a INT Default 0;
    DECLARE stop_loop INT Default 0;
    DECLARE domain_val VARCHAR(250);
    DECLARE domain_list CURSOR FOR SELECT DISTINCT domain FROM db.one;

    OPEN domain_list;

    SELECT COUNT(DISTINCT(domain)) INTO stop_loop 
    FROM db.one;
    -- BEGIN LOOP
    loop_thru_domains: LOOP
        FETCH domain_list INTO domain_val;
        SET a=a+1;

        INSERT INTO db.two(book,artist,title,title_count,last_updated) 
        SELECT * FROM 
        (
            SELECT book,artist,title,COUNT(ObjectKey) AS titleCount, NOW() 
            FROM db.one 
            WHERE book = domain_val
            GROUP BY artist,title
            ORDER BY book,titleCount DESC
            LIMIT 200
        ) a ON DUPLICATE KEY UPDATE title_count = titleCount, last_updated = NOW();

        IF a = stop_loop THEN
            LEAVE loop_thru_domain;
        END IF;
    END LOOP loop_thru_domain;
END $$

it loops through a list of domains and then inserts only a limit of 200 each

If you want to get an index about the similarity of the two pictures, I suggest you from the metrics the SSIM index. It is more consistent with the human eye. Here is an article about it: Structural Similarity Index

It is implemented in OpenCV too, and it can be accelerated with GPU: OpenCV SSIM with GPU

Using Stopwatch class we can achieve it from System.Diagnostics.

Stopwatch stopwatch  = new Stopwatch();
stopwatch.Start();
stopwatch.Stop();
Debug.WriteLine(stopwatch.ElapsedMilliseconds);

Powder's comment may go undetected like I missed it so many times,. So with the hope of making it more visible, I will re-iterate his point.

Sometimes using image = array(img).reshape(a,b,c,d) will reshape alright but from experience, my kernel crashes every time I try to use the new dimension in an operation. The safest to use is

np.expand_dims(img, axis=0)

It works perfect every time. I just can't explain why. This link has a great explanation and examples regarding its usage.

There are some problems with the Erlang implementation. As baseline for the following, my measured execution time for your unmodified Erlang program was 47.6 seconds, compared to 12.7 seconds for the C code.

The first thing you should do if you want to run computationally intensive Erlang code is to use native code. Compiling with erlc +native euler12 got the time down to 41.3 seconds. This is however a much lower speedup (just 15%) than expected from native compilation on this kind of code, and the problem is your use of -compile(export_all). This is useful for experimentation, but the fact that all functions are potentially reachable from the outside causes the native compiler to be very conservative. (The normal BEAM emulator is not that much affected.) Replacing this declaration with -export([solve/0]). gives a much better speedup: 31.5 seconds (almost 35% from the baseline).

But the code itself has a problem: for each iteration in the factorCount loop, you perform this test:

factorCount (_, Sqrt, Candidate, Count) when Candidate == Sqrt -> Count + 1;

The C code doesn't do this. In general, it can be tricky to make a fair comparison between different implementations of the same code, and in particular if the algorithm is numerical, because you need to be sure that they are actually doing the same thing. A slight rounding error in one implementation due to some typecast somewhere may cause it to do many more iterations than the other even though both eventually reach the same result.

To eliminate this possible error source (and get rid of the extra test in each iteration), I rewrote the factorCount function as follows, closely modelled on the C code:

factorCount (N) ->
    Sqrt = math:sqrt (N),
    ISqrt = trunc(Sqrt),
    if ISqrt == Sqrt -> factorCount (N, ISqrt, 1, -1);
       true          -> factorCount (N, ISqrt, 1, 0)
    end.

factorCount (_N, ISqrt, Candidate, Count) when Candidate > ISqrt -> Count;
factorCount ( N, ISqrt, Candidate, Count) ->
    case N rem Candidate of
        0 -> factorCount (N, ISqrt, Candidate + 1, Count + 2);
        _ -> factorCount (N, ISqrt, Candidate + 1, Count)
    end.

This rewrite, no export_all, and native compilation, gave me the following run time:

$ erlc +native euler12.erl
$ time erl -noshell -s euler12 solve
842161320

real    0m19.468s
user    0m19.450s
sys 0m0.010s

which is not too bad compared to the C code:

$ time ./a.out 
842161320

real    0m12.755s
user    0m12.730s
sys 0m0.020s

considering that Erlang is not at all geared towards writing numerical code, being only 50% slower than C on a program like this is pretty good.

Finally, regarding your questions:

Question 1: Do erlang, python and haskell loose speed due to using arbitrary length integers or don't they as long as the values are less than MAXINT?

Yes, somewhat. In Erlang, there is no way of saying "use 32/64-bit arithmetic with wrap-around", so unless the compiler can prove some bounds on your integers (and it usually can't), it must check all computations to see if they can fit in a single tagged word or if it has to turn them into heap-allocated bignums. Even if no bignums are ever used in practice at runtime, these checks will have to be performed. On the other hand, that means you know that the algorithm will never fail because of an unexpected integer wraparound if you suddenly give it larger inputs than before.

Question 4: Do my functional implementations permit LCO and hence avoid adding unnecessary frames onto the call stack?

Yes, your Erlang code is correct with respect to last call optimization.

boolean a = (x < z) && (x == x);

This kind will short-circuit, meaning if (x < z) evaluates to false then the latter is not evaluated, a will be false, otherwise && will also evaluate (x == x).

& is a bitwise operator, but also a boolean AND operator which does not short-circuit.

You can test them by something as follows (see how many times the method is called in each case):

public static boolean getFalse() {
    System.out.println("Method");
    return false;
}

public static void main(String[] args) {
    if(getFalse() && getFalse()) { }        
    System.out.println("=============================");        
    if(getFalse() & getFalse()) { }
}

you could get just the first row like:

with open('some.csv', newline='') as f:
  csv_reader = csv.reader(f)
  csv_headings = next(csv_reader)
  first_line = next(csv_reader)

Try this:

function btnClick() {
    var x = document.getElementById("mytable").getElementsByTagName("td");
    x[0].innerHTML = "i want to change my cell color";
    x[0].style.backgroundColor = "yellow";            
}

Set from JS, backgroundColor is the equivalent of background-color in your style-sheet.

Note also that the .cells collection belongs to a table row, not to the table itself. To get all the cells from all rows you can instead use getElementsByTagName().

Receive POST and GET request in nodejs :

1).Server

    var http = require('http');
    var server = http.createServer ( function(request,response){

    response.writeHead(200,{"Content-Type":"text\plain"});
    if(request.method == "GET")
        {
            response.end("received GET request.")
        }
    else if(request.method == "POST")
        {
            response.end("received POST request.");
        }
    else
        {
            response.end("Undefined request .");
        }
});

server.listen(8000);
console.log("Server running on port 8000");

2). Client :

var http = require('http');

var option = {
    hostname : "localhost" ,
    port : 8000 ,
    method : "POST",
    path : "/"
} 

    var request = http.request(option , function(resp){
       resp.on("data",function(chunck){
           console.log(chunck.toString());
       }) 
    })
    request.end();

You'll first get the dropdown element from the DOM, then loop through the array, and add each element as a new option in the dropdown like this:

// Get dropdown element from DOM
var dropdown = document.getElementById("selectNumber");

// Loop through the array
for (var i = 0; i < myArray.length; ++i) {
    // Append the element to the end of Array list
    dropdown[dropdown.length] = new Option(myArray[i], myArray[i]);
}?

See JSFiddle for a live demo: http://jsfiddle.net/nExgJ/

This assumes that you're not using JQuery, and you only have the basic DOM API to work with.

You can also check using a environment variable:

echo $HOSTTYPE

Result:

i386 -> 32 bits

x86_64 -> 64 bits

Extracted from: http://www.sysadmit.com/2016/02/linux-como-saber-si-es-32-o-64-bits.html

It is because display:inline-block takes into account white-space in the html. If you remove the white-space between the div's it works as expected. Live Example: http://jsfiddle.net/XCDsu/4/

<div id="col1">content</div><div id="col2">content</div>

require 'trollop'

opts = Trollop::options do
  opt :output, "Output file", :type => String
  opt :input, "Input file", :type => String
  opt :ss, "String to search", :type => String
  opt :rs, "String to replace", :type => String
end

text = File.read(opts.input)
text.gsub!(opts.ss, opts.rs)
File.open(opts.output, 'w') { |f| f.write(text) }

I got same situation in one of my Ajax calls, where JSON was throwing an error due to the newline in the Textarea field. The solution given here didn't worked for me. So i used Javascript's .escape function and it worked fine. Then to retrieve the value from JSON, I just unescaped using .unescape.

As per: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

9.2 OPTIONS

The OPTIONS method represents a request for information about the communication options available on the request/response chain identified by the Request-URI. This method allows the client to determine the options and/or requirements associated with a resource, or the capabilities of a server, without implying a resource action or initiating a resource retrieval.

Responses to this method are not cacheable.

If the OPTIONS request includes an entity-body (as indicated by the presence of Content-Length or Transfer-Encoding), then the media type MUST be indicated by a Content-Type field. Although this specification does not define any use for such a body, future extensions to HTTP might use the OPTIONS body to make more detailed queries on the server. A server that does not support such an extension MAY discard the request body.

If the Request-URI is an asterisk ("*"), the OPTIONS request is intended to apply to the server in general rather than to a specific resource. Since a server's communication options typically depend on the resource, the "*" request is only useful as a "ping" or "no-op" type of method; it does nothing beyond allowing the client to test the capabilities of the server. For example, this can be used to test a proxy for HTTP/1.1 compliance (or lack thereof).

If the Request-URI is not an asterisk, the OPTIONS request applies only to the options that are available when communicating with that resource.

A 200 response SHOULD include any header fields that indicate optional features implemented by the server and applicable to that resource (e.g., Allow), possibly including extensions not defined by this specification. The response body, if any, SHOULD also include information about the communication options. The format for such a body is not defined by this specification, but might be defined by future extensions to HTTP. Content negotiation MAY be used to select the appropriate response format. If no response body is included, the response MUST include a Content-Length field with a field-value of "0".

The Max-Forwards request-header field MAY be used to target a specific proxy in the request chain. When a proxy receives an OPTIONS request on an absoluteURI for which request forwarding is permitted, the proxy MUST check for a Max-Forwards field. If the Max-Forwards field-value is zero ("0"), the proxy MUST NOT forward the message; instead, the proxy SHOULD respond with its own communication options. If the Max-Forwards field-value is an integer greater than zero, the proxy MUST decrement the field-value when it forwards the request. If no Max-Forwards field is present in the request, then the forwarded request MUST NOT include a Max-Forwards field.

9.4 HEAD

The HEAD method is identical to GET except that the server MUST NOT return a message-body in the response. The metainformation contained in the HTTP headers in response to a HEAD request SHOULD be identical to the information sent in response to a GET request. This method can be used for obtaining metainformation about the entity implied by the request without transferring the entity-body itself. This method is often used for testing hypertext links for validity, accessibility, and recent modification.

The response to a HEAD request MAY be cacheable in the sense that the information contained in the response MAY be used to update a previously cached entity from that resource. If the new field values indicate that the cached entity differs from the current entity (as would be indicated by a change in Content-Length, Content-MD5, ETag or Last-Modified), then the cache MUST treat the cache entry as stale.

I use underscore's isNaN function because in JavaScript:

isNaN(undefined) 
-> true

At the least, be aware of that gotcha.

There are a number of reasons why the analysis portion of a compiler is normally separated into lexical analysis and parsing ( syntax analysis) phases.

1. Simplicity of design is the most important consideration. The separation of lexical and syntactic analysis often allows us to simplify at least one of these tasks. For example, a parser that had to deal with comments and white space as syntactic units would be. Considerably more complex than one that can assume comments and white space have already been removed by the lexical analyzer. If we are designing a new language, separating lexical and syntactic concerns can lead to a cleaner overall language design.
2. Compiler efficiency is improved. A separate lexical analyzer allows us to apply specialized techniques that serve only the lexical task, not the job of parsing. In addition, specialized buffering techniques for reading input characters can speed up the compiler significantly.
3. Compiler portability is enhanced. Input-device-specific peculiarities can be restricted to the lexical analyzer.

The following script is tested and gives exactly the results, that are expected

\#!/bin/bash

echo "Enter the file name"

read file

echo "enter the word to be found"

read word

do

if [ $i == $word ]

then

count=\`expr $count + 1`

fi

done

echo "The number of words are $count"

You remove the original image here:

newImg.animate(css, SPEED, function() {
    img.remove();
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And all that's left behind is newImg. Then you reset link references the image using #rocket:

$("#rocket").attr('src', ...

But your newImg doesn't have an id attribute let alone an id of rocket.

To fix this, you need to remove img and then set the id attribute of newImg to rocket:

newImg.animate(css, SPEED, function() {
    var old_id = img.attr('id');
    img.remove();
    newImg.attr('id', old_id);
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And then you'll get the shiny black rocket back again: http://jsfiddle.net/ambiguous/W2K9D/

UPDATE: A better approach (as noted by mellamokb) would be to hide the original image and then show it again when you hit the reset button. First, change the reset action to something like this:

$("#resetlink").click(function(){
    clearInterval(timerRocket);
    $("#wrapper").css('top', '250px');
    $('.throbber, .morpher').remove(); // Clear out the new stuff.
    $("#rocket").show();               // Bring the original back.
});

And in the newImg.load function, grab the images original size:

var orig = {
    width: img.width(),
    height: img.height()
};

And finally, the callback for finishing the morphing animation becomes this:

newImg.animate(css, SPEED, function() {
    img.css(orig).hide();
    (callback || function() {})();
});

New and improved: http://jsfiddle.net/ambiguous/W2K9D/1/

The leaking of $('.throbber, .morpher') outside the plugin isn't the best thing ever but it isn't a big deal as long as it is documented.

For a combobox (http://en.wikipedia.org/wiki/Combo_box) which allows free text input and has a dropdown listbox I used a AutoCompleteTextView as suggested by vbence.

I used the onClickListener to display the dropdown list box when the user selects the control.

I believe this resembles this kind of a combobox best.

private static final String[] STUFF = new String[] { "Thing 1", "Thing 2" };

public void onCreate(Bundle b) {
    final AutoCompleteTextView view = 
        (AutoCompleteTextView) findViewById(R.id.myAutoCompleteTextView);

    view.setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
                view.showDropDown();
        }
    });

    final ArrayAdapter<String> adapter = new ArrayAdapter<String>(
        this, 
        android.R.layout.simple_dropdown_item_1line,
        STUFF
    );
    view.setAdapter(adapter);
}

You cannot append to an existing xlsx file with xlsxwriter.

There is a module called openpyxl which allows you to read and write to preexisting excel file, but I am sure that the method to do so involves reading from the excel file, storing all the information somehow (database or arrays), and then rewriting when you call workbook.close() which will then write all of the information to your xlsx file.

Similarly, you can use a method of your own to "append" to xlsx documents. I recently had to append to a xlsx file because I had a lot of different tests in which I had GPS data coming in to a main worksheet, and then I had to append a new sheet each time a test started as well. The only way I could get around this without openpyxl was to read the excel file with xlrd and then run through the rows and columns...

i.e.

cells = []
for row in range(sheet.nrows):
    cells.append([])
    for col in range(sheet.ncols):
        cells[row].append(workbook.cell(row, col).value)

You don't need arrays, though. For example, this works perfectly fine:

import xlrd
import xlsxwriter

from os.path import expanduser
home = expanduser("~")

# this writes test data to an excel file
wb = xlsxwriter.Workbook("{}/Desktop/test.xlsx".format(home))
sheet1 = wb.add_worksheet()
for row in range(10):
    for col in range(20):
        sheet1.write(row, col, "test ({}, {})".format(row, col))
wb.close()

# open the file for reading
wbRD = xlrd.open_workbook("{}/Desktop/test.xlsx".format(home))
sheets = wbRD.sheets()

# open the same file for writing (just don't write yet)
wb = xlsxwriter.Workbook("{}/Desktop/test.xlsx".format(home))

# run through the sheets and store sheets in workbook
# this still doesn't write to the file yet
for sheet in sheets: # write data from old file
    newSheet = wb.add_worksheet(sheet.name)
    for row in range(sheet.nrows):
        for col in range(sheet.ncols):
            newSheet.write(row, col, sheet.cell(row, col).value)

for row in range(10, 20): # write NEW data
    for col in range(20):
        newSheet.write(row, col, "test ({}, {})".format(row, col))
wb.close() # THIS writes

However, I found that it was easier to read the data and store into a 2-dimensional array because I was manipulating the data and was receiving input over and over again and did not want to write to the excel file until it the test was over (which you could just as easily do with xlsxwriter since that is probably what they do anyway until you call .close()).

A more succinct idiom than the accepted answer above that's available in Rails (from 3.1.0 and above) is .in?:

my_string = "abcdefg"
if "cde".in? my_string
  puts "'cde' is in the String."
  puts "i.e. String includes 'cde'"
end

I also think it's more readable.

See the in? documentation for more information.

Note again that it's only available in Rails, and not pure Ruby.

Simple and even faster way to get it via ES6

let newArray = users.flatMap(i => i.ID) // -> [ 12, 13, 14, 15 ]

To make thepeer's answer work in IE 7 and forward, it needs a few tweaks.

1. IE will not honour z-index if the element is has no background-color, so the link will not overlap parts of the containig div that has content, only the blank parts. To fix this a background is added with opacity 0.

2. For some reason IE7 and various compatibility modes completely fail when using the span in a link approach. However if the link itself is given the style it works just fine.

.blockLink  
{  
    position:absolute;  
    top:0;  
    left: 0;  
    width:100%;  
    height:100%;  
    z-index: 1;  
    background-color:#ffffff;   
    -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";  
    filter: alpha(opacity=0);  
    opacity:0;  
}

<div style="position:relative">  
    <some content>  
    <a href="somepage" class="blockLink" />  
<div>

If you cannot use RowCounter for whatever reason, then a combination of these two filters should be an optimal way to get a count:

FirstKeyOnlyFilter() AND KeyOnlyFilter()

The FirstKeyOnlyFilter will result in the scanner only returning the first column qualifier it finds, as opposed to the scanner returning all of the column qualifiers in the table, which will minimize the network bandwith. What about simply picking one column qualifier to return? This would work if you could guarentee that column qualifier exists for every row, but if that is not true then you would get an inaccurate count.

The KeyOnlyFilter will result in the scanner only returning the column family, and will not return any value for the column qualifier. This further reduces the network bandwidth, which in the general case wouldn't account for much of a reduction, but there can be an edge case where the first column picked by the previous filter just happens to be an extremely large value.

I tried playing around with scan.setCaching but the results were all over the place. Perhaps it could help.

I had 16 million rows in between a start and stop that I did the following pseudo-empirical testing:

With FirstKeyOnlyFilter and KeyOnlyFilter activated:

    With caching not set (i.e., the default value), it took 188 seconds.
    With caching set to 1, it took 188 seconds
    With caching set to 10, it took 200 seconds
    With caching set to 100, it took 187 seconds
    With caching set to 1000, it took 183 seconds.
    With caching set to 10000, it took 199 seconds.
    With caching set to 100000, it took 199 seconds.

With FirstKeyOnlyFilter and KeyOnlyFilter disabled:

    With caching not set, (i.e., the default value), it took 309 seconds

I didn't bother to do proper testing on this, but it seems clear that the FirstKeyOnlyFilter and KeyOnlyFilter are good.

Moreover, the cells in this particular table are very small - so I think the filters would have been even better on a different table.

Here is a Java code sample:

import java.io.IOException;

import org.apache.hadoop.conf.Configuration;
import org.apache.hadoop.hbase.HBaseConfiguration;
import org.apache.hadoop.hbase.client.HTable;
import org.apache.hadoop.hbase.client.Result;
import org.apache.hadoop.hbase.client.ResultScanner;
import org.apache.hadoop.hbase.client.Scan;
import org.apache.hadoop.hbase.util.Bytes;

import org.apache.hadoop.hbase.filter.RowFilter;
import org.apache.hadoop.hbase.filter.KeyOnlyFilter; 
import org.apache.hadoop.hbase.filter.FirstKeyOnlyFilter; 
import org.apache.hadoop.hbase.filter.FilterList;

import org.apache.hadoop.hbase.filter.CompareFilter.CompareOp;
import org.apache.hadoop.hbase.filter.RegexStringComparator; 

public class HBaseCount {
    public static void main(String[] args) throws IOException {
        Configuration config = HBaseConfiguration.create();

        HTable table = new HTable(config, "my_table");

        Scan scan = new Scan(
            Bytes.toBytes("foo"), Bytes.toBytes("foo~")
        );

        if (args.length == 1) {
            scan.setCaching(Integer.valueOf(args[0]));
        }
        System.out.println("scan's caching is " + scan.getCaching());

        FilterList allFilters = new FilterList();
        allFilters.addFilter(new FirstKeyOnlyFilter());
        allFilters.addFilter(new KeyOnlyFilter());

        scan.setFilter(allFilters);

        ResultScanner scanner = table.getScanner(scan);

        int count = 0;

        long start = System.currentTimeMillis();

        try {
            for (Result rr = scanner.next(); rr != null; rr = scanner.next()) {
                count += 1;
                if (count % 100000 == 0) System.out.println(count);
            }
        } finally {
            scanner.close();
        }

        long end = System.currentTimeMillis();

        long elapsedTime = end - start;

        System.out.println("Elapsed time was " + (elapsedTime/1000F));

    }
}

Here is a pychbase code sample:

    from pychbase import Connection
    c = Connection()
    t = c.table('my_table')
    # Under the hood this applies the FirstKeyOnlyFilter and KeyOnlyFilter
    # similar to the happybase example below
    print t.count(row_prefix="foo")

Here is a Happybase code sample:

    from happybase import Connection
    c = Connection(...)
    t = c.table('my_table')
    count = 0
    for _ in t.scan(filter='FirstKeyOnlyFilter() AND KeyOnlyFilter()'):
        count += 1

    print count

Thanks to @Tuckr and @KennyCason for the tip.

As the other answers mentioned, dispatch_async from the main thread is fine.

However, depending on your use case, there is a side effect that you may consider a disadvantage: since the block is scheduled on a queue, it won't execute until control goes back to the run loop, which will have the effect of delaying your block's execution.

For example,

NSLog(@"before dispatch async");
dispatch_async(dispatch_get_main_queue(), ^{
    NSLog(@"inside dispatch async block main thread from main thread");
});
NSLog(@"after dispatch async");

Will print out:

before dispatch async
after dispatch async
inside dispatch async block main thread from main thread

For this reason, if you were expecting the block to execute in-between the outer NSLog's, dispatch_async would not help you.

Use this JavaScript.

$(":input").inputmask();
$("#phone").inputmask({"mask": "(999) 999-9999"});

Even though 7 years have passed I've just run into this issue as I'm running SpringBoot application that needs to start webpack-dev-server during development and needs to kill it when the backend process stops.

I try to use Runtime.getRuntime().addShutdownHook but it worked on Windows 10 but not on Windows 7.

I've change it to use a dedicated thread that waits for the process to quit or for InterruptedException which seems to work correctly on both Windows versions.

private void startWebpackDevServer() {
    String cmd = isWindows() ? "cmd /c gradlew webPackStart" : "gradlew webPackStart";
    logger.info("webpack dev-server " + cmd);

    Thread thread = new Thread(() -> {

        ProcessBuilder pb = new ProcessBuilder(cmd.split(" "));
        pb.redirectOutput(ProcessBuilder.Redirect.INHERIT);
        pb.redirectError(ProcessBuilder.Redirect.INHERIT);
        pb.directory(new File("."));

        Process process = null;
        try {
            // Start the node process
            process = pb.start();

            // Wait for the node process to quit (blocking)
            process.waitFor();

            // Ensure the node process is killed
            process.destroyForcibly();
            System.setProperty(WEBPACK_SERVER_PROPERTY, "true");
        } catch (InterruptedException | IOException e) {
            // Ensure the node process is killed.
            // InterruptedException is thrown when the main process exit.
            logger.info("killing webpack dev-server", e);
            if (process != null) {
                process.destroyForcibly();
            }
        }

    });

    thread.start();
}

$("#bchange").click(function() {
    $("body, this").css("background-color","yellow");
});

this will also work, if you like

 xcopy  C:\Test\Log "c:\Test\Backup-%date:~4,2%-%date:~7,2%-%date:~10,4%_%time:~0,2%%time:~3,2%" /s /i
 del C:\Test\Log

I was facing same issue in VS 2019. if anyone still facing same issue then please make sure you have/do following things:

1. You should have SQL Express installed on your m/c
2. Should have SSDT installed in VS (in VS 2019- make sure to check this component while installing) for previous versions - you have to add this component externally
3. Add 'User Instance = True' to your connectionstring
4. I think its optional - open VS and SQL Express in administrative mode and login as admin to SQL Express

I would use this syntax

Delete a 
from TableA a
Inner Join TableB b
on  a.BId = b.BId
WHERE [filter condition]

Why not just use that:

manage.py inspectdb

Example output:

class GuardianUserobjectpermission(models.Model):
    id = models.IntegerField(primary_key=True)  # AutoField?
    object_pk = models.CharField(max_length=255)
    content_type = models.ForeignKey(DjangoContentType, models.DO_NOTHING)
    permission = models.ForeignKey(AuthPermission, models.DO_NOTHING)
    user = models.ForeignKey(CustomUsers, models.DO_NOTHING)

    class Meta:
        managed = False
        db_table = 'guardian_userobjectpermission'
        unique_together = (('user', 'permission', 'object_pk'),)

I fixed this issue

just only type this command: jupyter notebook --no-browser

It will show you the path then copy and paste on Jupyter Notebook browser

The code will be executed in IPython Notebook Python 3

Once you have downloaded the Flutter SDK for your specific OS.

Unzip the file. Copy it to a better place. Your Flutter SDK path should be a_better_place/flutter. These would be used in tools such as VSCode or Android Studio.

For command line, you would add a_better_place/flutter/bin. Such as export PATH=a_better_place/flutter/bin:$PATH

I added TO_DATE and it resolved issue.

Before modification - due to below condition i got this error

record_update_dt>='05-May-2017'

After modification - after adding to_date, issue got resolved.

record_update_dt>=to_date('05-May-2017','DD-Mon-YYYY')

Try this:

window.open('', '_self').close();

tl;dr What to do in modern (2018) times? Assume tel: is supported, use it and forget about anything else.

The tel: URI scheme RFC5431 (as well as sms: but also feed:, maps:, youtube: and others) is handled by protocol handlers (as mailto: and http: are).

They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto: protocol handler with same meaning and behaviour of tel: but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.

What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler() and related functions) simplifying also the check for their support through isProtocolHandlerRegistered() function.

There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).

In general what I suggest is:

1. If you're running on a mobile device then you can safely assume tel: is supported (yes, it's not true for very old devices but IMO you can ignore them).
2. If JS isn't active then do nothing.
3. If you're running on desktop browsers then you can use one of the techniques in the linked post to determine if it's supported.
4. If tel: isn't supported then change links to use callto: and repeat check desctibed in 3.
5. If tel: and callto: aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href with javascript:void(0) and (if number isn't repeated in text span) putting, telephone number in title. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto: and tel:.

Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:

1. If you're running on a mobile device then assume tel: is supported.
2. If you're running on desktop then replace tel: with callto:. then drop tel: or leave it as is (assuming there are good chances Skype is installed).

This was pretty well answered over here: How to make a YouTube embedded video a full page width one?

If you add '?rel=0&autoplay=1' to the end of the url in the embed code (like this)

<iframe id="video" src="//www.youtube.com/embed/5iiPC-VGFLU?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>

of the video it should play on load. Here's a demo over at jsfiddle.

It may worth taking a look at the crtime library which implements cross-platform access to the file creation time.

from crtime import get_crtimes_in_dir

for fname, date in get_crtimes_in_dir(".", raise_on_error=True, as_epoch=False):
    print(fname, date)
    # file_a.py Mon Mar 18 20:51:18 CET 2019

If you do not want to specify a message with your stashed changes, pass the filename after a double-dash.

$ git stash -- filename.ext

If it's an untracked/new file, you will have to stage it first.

However, if you do want to specify a message, use push.

git stash push -m "describe changes to filename.ext" filename.ext

Both methods work in git versions 2.13+

If you care about performance, then the thing you want to avoid here are allocations. And if you're on .Net Core 2.1+ (or the, as yet unreleased, .Net Standard 2.1), then you can, by using the string.Create method:

public static string ReplaceAt(this string str, int index, int length, string replace)
{
    return string.Create(str.Length - length + replace.Length, (str, index, length, replace),
        (span, state) =>
        {
            state.str.AsSpan().Slice(0, state.index).CopyTo(span);
            state.replace.AsSpan().CopyTo(span.Slice(state.index));
            state.str.AsSpan().Slice(state.index + state.length).CopyTo(span.Slice(state.index + state.replace.Length));
        });
}

This approach is harder to understand than the alternatives, but it's the only one that will allocate only one object per call: the newly created string.

One thing that caused me a massive headache when using this code (might affect others and I wish that somebody had left a comment like this one here for me to read):

• My aim is to create a dynamic access dashboard, which requires that its linked tables be updated.
• I use the copy methods described above to replace the existing linked CSVs with an updated version of them.
• Running the above code manually from a module worked fine.
• Running identical code from a form linked to the CSV data had runtime error 70 (Permission denied), even tho the first step of my code was to close that form (which should have unlocked the CSV file so that it could be overwritten).
• I now believe that despite the form being closed, it keeps the outdated CSV file locked while it executes VBA associated with that form.

My solution will be to run the code (On timer event) from another hidden form that opens with the database.

I solved it in this way

A pkg-config file describes all necessary compile-time and link-time flags and dependencies needed to use a library.

pkg-config --static --libs glfw3

shows me that

-L/usr/local/lib -lglfw3 -lrt -lXrandr -lXinerama -lXi -lXcursor -lGL -lm -ldl -lXrender -ldrm -lXdamage -lX11-xcb -lxcb-glx -lxcb-dri2 -lxcb-dri3 -lxcb-present -lxcb-sync -lxshmfence -lXxf86vm -lXfixes -lXext -lX11 -lpthread -lxcb -lXau -lXdmcp  

I don't know if all these libs are actually necessary for compiling but for me it works...

Whenever one has a dictionary where the values are integers, the Counter data structure is often a better choice to represent the data than a dictionary.

If you already have a dictionary, a counter can easily be formed by:

c = Counter(d['123'])

as an example from your data.

The most_common function allows easy access to descending order of the items in the counter

The more complete writeup on the Counter data structure is at https://docs.python.org/2/library/collections.html

print(spam)

You can use good old ed to edit a file in a similar fashion to the answer that uses ex. The big difference in this case is that ed takes its commands via standard input, not as command line arguments like ex can. When using it in a script, the usual way to accomodate this is to use printf to pipe commands to it:

printf "%s\n" "g/pattern/d" w | ed -s filename

or with a heredoc:

ed -s filename <<EOF
g/pattern/d
w
EOF

The result of getElementsByClassName() is not an Array, but an array-like object. Specifically it's called an HTMLCollection, not to be confused with NodeList (which has it's own forEach() method).

One simple way with ES2015 to convert an array-like object for use with Array.prototype.forEach() that hasn't been mentioned yet is to use the spread operator or spread syntax:

const elementsArray = document.getElementsByClassName('myclass');

[...elementsArray].forEach((element, index, array) => {
    // do something
});

According to spark documentation "where() is an alias for filter()"

filter(condition) Filters rows using the given condition. where() is an alias for filter().

Parameters: condition – a Column of types.BooleanType or a string of SQL expression.

>>> df.filter(df.age > 3).collect()
[Row(age=5, name=u'Bob')]
>>> df.where(df.age == 2).collect()
[Row(age=2, name=u'Alice')]

>>> df.filter("age > 3").collect()
[Row(age=5, name=u'Bob')]
>>> df.where("age = 2").collect()
[Row(age=2, name=u'Alice')]

<ul id="unOrderedList">
<li value="2">Whatever</li>
.
.



 $('#unOrderedList li').click(function(){

  });

Your looking for the attribute "value" inside the "li" tag

Since ECMAScript6, one can use Set :

var myArray = ['A', 'B', 'C'];
var mySet = new Set(myArray);
var hasB = mySet.has('B'); // true
var hasZ = mySet.has('Z'); // false

I was looking for something along what you wanted, but wanted to put it back into a variable.

So this is what I did

variable = ['hello this is x' x ', this is now y' y ', finally this is d:' d]

basically

variable = [str1 str2 str3 str4 str5 str6]

Here is an example of how to do it with an arrow instead of a + and -. This uses jQuery to change classes on the element, and CSS to style the arrow.

$(".toggleHide").click(function() {_x000D_
  $(".elementToHide").slideToggle("fast");_x000D_
  $(this).find("i").toggleClass("down up");_x000D_
});

i {_x000D_
  border: solid black;_x000D_
  border-width: 0 5px 5px 0;_x000D_
  display: inline-block;_x000D_
  padding: 5px;_x000D_
  -webkit-transition-duration: 1s;_x000D_
  /* Safari */_x000D_
  transition-duration: 1s;_x000D_
}_x000D_
_x000D_
.up {_x000D_
  transform: rotate(-135deg);_x000D_
  -webkit-transform: rotate(-135deg);_x000D_
}_x000D_
_x000D_
.down {_x000D_
  transform: rotate(45deg);_x000D_
  -webkit-transform: rotate(45deg);_x000D_
}

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

Note that if you want to scroll an element instead of the full window, elements don't have the scrollTo and scrollBy methods. You should:

var el = document.getElementById("myel"); // Or whatever method to get the element

// To set the scroll
el.scrollTop = 0;
el.scrollLeft = 0;

// To increment the scroll
el.scrollTop += 100;
el.scrollLeft += 100;

You can also mimic the window.scrollTo and window.scrollBy functions to all the existant HTML elements in the webpage on browsers that don't support it natively:

Object.defineProperty(HTMLElement.prototype, "scrollTo", {
    value: function(x, y) {
        el.scrollTop = y;
        el.scrollLeft = x;
    },
    enumerable: false
});

Object.defineProperty(HTMLElement.prototype, "scrollBy", {
    value: function(x, y) {
        el.scrollTop += y;
        el.scrollLeft += x;
    },
    enumerable: false
});

so you can do:

var el = document.getElementById("myel"); // Or whatever method to get the element, again

// To set the scroll
el.scrollTo(0, 0);

// To increment the scroll
el.scrollBy(100, 100);

NOTE: Object.defineProperty is encouraged, as directly adding properties to the prototype is a breaking bad habit (When you see it :-).

Is there a way to get a list of all the keys in a Go language map?

ks := reflect.ValueOf(m).MapKeys()

how do I iterate over all the keys?

Use the accepted answer:

for k, _ := range m { ... }

For simple UTF-8 encoding, with slightly better compatibility than TextEncoder, Blob does the trick. Won't work in very old browsers though.

new Blob([""]).size; // -> 4  

If you're using SQL Server 2005, you could use the FOR XML PATH command.

SELECT [VehicleID]
     , [Name]
     , (STUFF((SELECT CAST(', ' + [City] AS VARCHAR(MAX)) 
         FROM [Location] 
         WHERE (VehicleID = Vehicle.VehicleID) 
         FOR XML PATH ('')), 1, 2, '')) AS Locations
FROM [Vehicle]

It's a lot easier than using a cursor, and seems to work fairly well.

If you have PowerShell 5.0 or higher (pre-installed with Windows 10 and Windows Server 2016):

powershell Expand-Archive your.zip -DestinationPath your_destination

Use cURL,

Check if you have it via phpinfo();

And for the code:

function getHtml($url, $post = null) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    if(!empty($post)) {
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    } 
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

Since localStorage is a global object, you can add a watch in the dev tools. Just enter the dev tools, goto "watch", click on "Click to add..." and type in "localStorage".

I think this is along the lines of what you're looking for. It appears that you want to see the orderid, the subtotal for each item in the order and the total amount for the order.

select o1.orderID, o1.subtotal, sum(o2.UnitPrice * o2.Quantity) as order_total from
(
    select o.orderID, o.price * o.qty as subtotal
    from product p inner join orderitem o on p.ProductID= o.productID
    where o.orderID = @OrderId
)as o1
inner join orderitem o2 on o1.OrderID = o2.OrderID
group by o1.orderID, o1.subtotal

Divide a division in two columns is very easy, just specify the width of your column better if you put this (like width:50%) and set the float:left for left column and float:right for right column.

If they all have the same extension (for example .jpg), you can use this:

for picture in  *.jpg ; do
    echo "the next file is $picture"
done

(This solution also works if the filename has spaces)

How about adding a new script tag to <head> with the script to (re)load? Something like below:

<script>
   function load_js()
   {
      var head= document.getElementsByTagName('head')[0];
      var script= document.createElement('script');
      script.src= 'source_file.js';
      head.appendChild(script);
   }
   load_js();
</script>

The main point is inserting a new script tag -- you can remove the old one without consequence. You may need to add a timestamp to the query string if you have caching issues.

I tried to make this as efficient as possible.

It uses a generator; those unfamiliar with these beasts are advised to check out their documentation and that of yield expressions.

Basically it creates a generator of values from the subsequence that can be reset by sending it a true value. If the generator is reset, it starts yielding again from the beginning of sub.

Then it just compares successive values of sequence with the generator yields, resetting the generator if they don't match.

When the generator runs out of values, i.e. reaches the end of sub without being reset, that means that we've found our match.

Since it works for any sequence, you can even use it on strings, in which case it behaves similarly to str.find, except that it returns False instead of -1.

As a further note: I think that the second value of the returned tuple should, in keeping with Python standards, normally be one higher. i.e. "string"[0:2] == "st". But the spec says otherwise, so that's how this works.

It depends on if this is meant to be a general-purpose routine or if it's implementing some specific goal; in the latter case it might be better to implement a general-purpose routine and then wrap it in a function which twiddles the return value to suit the spec.

def reiterator(sub):
    """Yield elements of a sequence, resetting if sent ``True``."""
    it = iter(sub)
    while True:
        if (yield it.next()):
            it = iter(sub)

def find_in_sequence(sub, sequence):
    """Find a subsequence in a sequence.

    False
    >>> find_in_sequence([0, 1, 2], [-1, 0, 1, 2])
    (1, 3)
    >>> find_in_sequence("subsequence",
    ...                  "This sequence contains a subsequence.")
    (25, 35)
    >>> find_in_sequence("subsequence", "This one doesn't.")
    False

    """
    start = None
    sub_items = reiterator(sub)
    sub_item = sub_items.next()
    for index, item in enumerate(sequence):
        if item == sub_item:
            if start is None: start = index
        else:
            start = None
        try:
            sub_item = sub_items.send(start is None)
        except StopIteration:
            # If the subsequence is depleted, we win!
            return (start, index)
    return False

Only a teacher would ask you to do something silly like this. You could provide an expected answer. Or a unique solution, while the rest of the class will be (yawn) the same...

from operator import lt, gt
def ultimate (l,op,c=1,u=0):
    try:
        if op(l[c],l[u]): 
            u = c
        c += 1
        return ultimate(l,op,c,u)
    except IndexError:
        return l[u]
def minimum (l):
    return ultimate(l,lt)
def maximum (l):
    return ultimate(l,gt)

The solution is simple. Use this to set yourself apart from obvious choices.

Lambda Expressions

To add on to jk.'s excellent answer, you can now pass a method more easily using Lambda Expressions (in Java 8). First, some background. A functional interface is an interface that has one and only one abstract method, although it can contain any number of default methods (new in Java 8) and static methods. A lambda expression can quickly implement the abstract method, without all the unnecessary syntax needed if you don't use a lambda expression.

Without lambda expressions:

obj.aMethod(new AFunctionalInterface() {
    @Override
    public boolean anotherMethod(int i)
    {
        return i == 982
    }
});

With lambda expressions:

obj.aMethod(i -> i == 982);

Here is an excerpt from the Java tutorial on Lambda Expressions:

Syntax of Lambda Expressions

A lambda expression consists of the following:

• A comma-separated list of formal parameters enclosed in parentheses. The CheckPerson.test method contains one parameter, p, which represents an instance of the Person class.
  
  Note: You can omit the data type of the parameters in a lambda expression. In addition, you can omit the parentheses if there is only one parameter. For example, the following lambda expression is also valid:

  p -> p.getGender() == Person.Sex.MALE 
      && p.getAge() >= 18
      && p.getAge() <= 25
  

• The arrow token, ->

• A body, which consists of a single expression or a statement block. This example uses the following expression:

  p.getGender() == Person.Sex.MALE 
      && p.getAge() >= 18
      && p.getAge() <= 25
  

  If you specify a single expression, then the Java runtime evaluates the expression and then returns its value. Alternatively, you can use a return statement:

  p -> {
      return p.getGender() == Person.Sex.MALE
          && p.getAge() >= 18
          && p.getAge() <= 25;
  }
  

  A return statement is not an expression; in a lambda expression, you must enclose statements in braces ({}). However, you do not have to enclose a void method invocation in braces. For example, the following is a valid lambda expression:

  email -> System.out.println(email)
  

Note that a lambda expression looks a lot like a method declaration; you can consider lambda expressions as anonymous methods—methods without a name.

Here is how you can "pass a method" using a lambda expression:

^{Note: this uses a new standard functional interface, java.util.function.IntConsumer.}

class A {
    public static void methodToPass(int i) { 
        // do stuff
    }
}

import java.util.function.IntConsumer;

class B {
    public void dansMethod(int i, IntConsumer aMethod) {
        /* you can now call the passed method by saying aMethod.accept(i), and it
        will be the equivalent of saying A.methodToPass(i) */
    }
}

class C {
    B b = new B();

    public C() {
        b.dansMethod(100, j -> A.methodToPass(j));   //Lambda Expression here
    }
}

The above example can be shortened even more using the :: operator.

public C() {
    b.dansMethod(100, A::methodToPass);
}

For the first one remove the spaces. Whitespace matters for the set command.

set guifont=Monaco:h20

For the second one it should be (the h specifies the height)

set guifont=Monospace:h20

My recommendation for setting the font is to do (if your version supports it)

set guifont=*

This will pop up a menu that allows you to select the font. After selecting the font, type

set guifont?

To show what the current guifont is set to. After that copy that line into your vimrc or gvimrc. If there are spaces in the font add a \ to escape the space.

set guifont=Monospace\ 20

right click on app-->select

New-->Select Folder-->then click on Assets Folder

The message is fairly self-explanatory; your working directory should not be the NumPy source directory when you invoke Python; NumPy should be installed and your working directory should be anything but the directory where it lives.

I normally use the history object for this. It also does not reload the page.

Example:

history.pushState({}, '', 
                `/pagepath/path?query=${this.myQueryParam}`);

I encountered this issue in my conda environment. The reason is that packages have been installed into two different folders, only one of which is recognised by the Python executable.

~/anaconda2/envs/[my_env]/site-packages ~/anaconda2/envs/[my_env]/lib/python2.7/site-packages

A proved solution is to add both folders to python path, using the following steps in command line (Please replace [my_env] with your own environment):

1. conda activate [my_env].
2. conda-develop ~/anaconda2/envs/[my_env]/site-packages
3. conda-develop ~/anaconda2/envs/[my_env]/lib/python2.7/site-packages (conda-develop is to add a .pth file to the folder so that the Python executable knows of this folder when searching for packages.)

To ensure this works, try to activate Python in this environment, and import the package that was not found.

I found a solution that works for me:

$.fn.setCursorPosition = function(position){
    if(this.length == 0) return this;
    return $(this).setSelection(position, position);
}

$.fn.setSelection = function(selectionStart, selectionEnd) {
    if(this.length == 0) return this;
    var input = this[0];

    if (input.createTextRange) {
        var range = input.createTextRange();
        range.collapse(true);
        range.moveEnd('character', selectionEnd);
        range.moveStart('character', selectionStart);
        range.select();
    } else if (input.setSelectionRange) {
        input.focus();
        input.setSelectionRange(selectionStart, selectionEnd);
    }

    return this;
}

$.fn.focusEnd = function(){
    this.setCursorPosition(this.val().length);
            return this;
}

Now you can move the focus to the end of any element by calling:

$(element).focusEnd();

Or you specify the position.

$(element).setCursorPosition(3); // This will focus on the third character.

Got a reply from @Vjeux over at the React team:

Normal HTML/CSS:

<div class="something"><span>Something</span></div>
<style>
    .something::after {
    content: '';
    position: absolute;
    -webkit-filter: blur(10px) saturate(2);
}
</style>

React with inline style:

render: function() {
    return (
        <div>
          <span>Something</span>
          <div style={{position: 'absolute', WebkitFilter: 'blur(10px) saturate(2)'}} />
        </div>
    );
},

The trick is that instead of using ::after in CSS in order to create a new element, you should instead create a new element via React. If you don't want to have to add this element everywhere, then make a component that does it for you.

For special attributes like -webkit-filter, the way to encode them is by removing dashes - and capitalizing the next letter. So it turns into WebkitFilter. Note that doing {'-webkit-filter': ...} should also work.

That’s right, Executors.newCachedThreadPool() isn't a great choice for server code that's servicing multiple clients and concurrent requests.

Why? There are basically two (related) problems with it:

1. It's unbounded, which means that you're opening the door for anyone to cripple your JVM by simply injecting more work into the service (DoS attack). Threads consume a non-negligible amount of memory and also increase memory consumption based on their work-in-progress, so it's quite easy to topple a server this way (unless you have other circuit-breakers in place).

2. The unbounded problem is exacerbated by the fact that the Executor is fronted by a SynchronousQueue which means there's a direct handoff between the task-giver and the thread pool. Each new task will create a new thread if all existing threads are busy. This is generally a bad strategy for server code. When the CPU gets saturated, existing tasks take longer to finish. Yet more tasks are being submitted and more threads created, so tasks take longer and longer to complete. When the CPU is saturated, more threads is definitely not what the server needs.

Here are my recommendations:

Use a fixed-size thread pool Executors.newFixedThreadPool or a ThreadPoolExecutor. with a set maximum number of threads;

For laughs I roughly just quickly worked out a set of functions to do this (is_string, is_int, is_float, is alpha string, or other) but there are more efficient (less code) ways to do this:

#!/bin/bash

function strindex() {
    x="${1%%$2*}"
    if [[ "$x" = "$1" ]] ;then
        true
    else
        if [ "${#x}" -gt 0 ] ;then
            false
        else
            true
        fi
    fi
}

function is_int() {
    if is_empty "${1}" ;then
        false
        return
    fi
    tmp=$(echo "${1}" | sed 's/[^0-9]*//g')
    if [[ $tmp == "${1}" ]] || [[ "-${tmp}" == "${1}" ]] ; then
        #echo "INT (${1}) tmp=$tmp"
        true
    else
        #echo "NOT INT (${1}) tmp=$tmp"
        false
    fi
}

function is_float() {
    if is_empty "${1}" ;then
        false
        return
    fi
    if ! strindex "${1}" "-" ; then
        false
        return
    fi
    tmp=$(echo "${1}" | sed 's/[^a-z. ]*//g')
    if [[ $tmp =~ "." ]] ; then
        #echo "FLOAT  (${1}) tmp=$tmp"
        true
    else
        #echo "NOT FLOAT  (${1}) tmp=$tmp"
        false
    fi
}

function is_strict_string() {
    if is_empty "${1}" ;then
        false
        return
    fi
    if [[ "${1}" =~ ^[A-Za-z]+$ ]]; then
        #echo "STRICT STRING (${1})"
        true
    else
        #echo "NOT STRICT STRING (${1})"
        false
    fi
}

function is_string() {
    if is_empty "${1}" || is_int "${1}" || is_float "${1}" || is_strict_string "${1}" ;then
        false
        return
    fi
    if [ ! -z "${1}" ] ;then
        true
        return
    fi
    false
}
function is_empty() {
    if [ -z "${1// }" ] ;then
        true
    else
        false
    fi
}

Run through some tests here, I defined that -44 is an int but 44- isn't etc.. :

for num in "44" "-44" "44-" "4-4" "a4" "4a" ".4" "4.4" "-4.4" "09" "hello" "h3llo!" "!!" " " "" ; do
    if is_int "$num" ;then
        echo "INT = $num"

    elif is_float "$num" ;then
        echo "FLOAT = $num"

    elif is_string "$num" ; then
        echo "STRING = $num"

    elif is_strict_string "$num" ; then
        echo "STRICT STRING = $num"
    else
        echo "OTHER = $num"
    fi
done

Output:

INT = 44
INT = -44
STRING = 44-
STRING = 4-4
STRING = a4
STRING = 4a
FLOAT = .4
FLOAT = 4.4
FLOAT = -4.4
INT = 09
STRICT STRING = hello
STRING = h3llo!
STRING = !!
OTHER =  
OTHER = 

NOTE: Leading 0's could infer something else when adding numbers such as octal so it would be better to strip them if you intend on treating '09' as an int (which I'm doing) (eg expr 09 + 0 or strip with sed)

Click the arrow in the screenshot and find the bash with already running Django server. You were getting the message because your server was already running and you tried to start the server again.

I could care less about IE6, as long as it works in IE8, Firefox 4, and Safari 5

This makes me happy.

Try this: Live Demo

display: table is surprisingly good. Once you don't care about IE7, you're free to use it. It doesn't really have any of the usual downsides of <table>.

CSS:

#container {
    background: #ccc;
    display: table
}
#left, #right {
    display: table-cell
}
#left {
    width: 150px;
    background: #f0f;
    border: 5px dotted blue;
}
#right {
    background: #aaa;
    border: 3px solid #000
}

Modify the following rc parameters by adding the commands to the script:

plt.rcParams['xtick.bottom'] = False
plt.rcParams['xtick.labelbottom'] = False

A sample matplotlibrc file is depicted in this section of the matplotlib documentation, which lists many other parameters like changing figure size, color of figure, animation settings, etc.

You can add to the system-path at runtime:

import sys
sys.path.insert(0, 'path/to/your/py_file')

import py_file

This is by far the easiest way to do it.

ln -s sourcepath linkpathname

Note:

-s makes symbolic links instead of hard links

Exiting from Java running process is very easy, basically you need to do just two simple things:

1. Call java method System.exit(...) at at application's quit point. For example, if your application is frame based, you can add listener WindowAdapter and and call System.exit(...) inside its method windowClosing(WindowEvent e).

Note: you must call System.exit(...) otherwise your program is error involved.

2. Avoiding unexpected java exceptions to make sure the exit method can be called always. If you add System.exit(...) at right point, but It does not mean that the method can be called always, because unexpected java exceptions may prevent the method from been called.

This is strongly related to your programming skills.

** Following is a simplest sample (JFrame based) which shows you how to call exit method

import java.awt.event.*;
import javax.swing.*;

public class ExitApp extends JFrame
{
   public ExitApp()
   {
      addWindowListener(new WindowAdapter()
      {
         public void windowClosing(WindowEvent e)
         {
           dispose();
           System.exit(0); //calling the method is a must
         }
      });
   }

   public static void main(String[] args)
   {
      ExitApp app=new ExitApp();
      app.setBounds(133,100,532,400);
      app.setVisible(true);
   }
}

In my case, I was uploading the wrong apk, to another app's release.

Try:

set sw=2

set ts=2

set smartindent

readelf -a xxx

There is, however, no guarantee that the output of SDTOUT and STDERR are interweaved line-by-line in timely order, using the POSIX redirect merge syntax.

If an application uses buffered output, it may happen that the text of one stream is inserted in the other at a buffer boundary, which may appear in the middle of a text line.

A dedicated console output logger (I.e. the "StdOut/StdErr Logger" by 'LoRd MuldeR') may be more reliable for such a task.

See: MuldeR's OpenSource Projects

git stash drop takes no parameter - which drops the top stash - or a stash reference which looks like: stash@{n} which n nominates which stash to drop. You can't pass a commit id to git stash drop.

git stash drop            # drop top hash, stash@{0}
git stash drop stash@{n}  # drop specific stash - see git stash list

Dropping a stash will change the stash@{n} designations of all stashes further down the stack.

I'm not sure why you think need to drop a stash because if you are using stash create a stash entry isn't created for your "stash" so there isn't anything to drop.

You can simply use shell commands. If you want to suppress echoing the output, use the "@" sign. For example:

clean:
    @if [ "test" = "test" ]; then\
        echo "Hello world";\
    fi

Note that the closing ";" and "\" are necessary.

Single Buffer

If you have a single Buffer you can use its toString method that will convert all or part of the binary contents to a string using a specific encoding. It defaults to utf8 if you don't provide a parameter, but I've explicitly set the encoding in this example.

var req = http.request(reqOptions, function(res) {
    ...

    res.on('data', function(chunk) {
        var textChunk = chunk.toString('utf8');
        // process utf8 text chunk
    });
});

Streamed Buffers

If you have streamed buffers like in the question above where the first byte of a multi-byte UTF8-character may be contained in the first Buffer (chunk) and the second byte in the second Buffer then you should use a StringDecoder. :

var StringDecoder = require('string_decoder').StringDecoder;

var req = http.request(reqOptions, function(res) {
    ...
    var decoder = new StringDecoder('utf8');

    res.on('data', function(chunk) {
        var textChunk = decoder.write(chunk);
        // process utf8 text chunk
    });
});

This way bytes of incomplete characters are buffered by the StringDecoder until all required bytes were written to the decoder.

There is a modern port for this Turbo C graphics interface, it's called WinBGIM, which emulates BGI graphics under MinGW/GCC.

I haven't it tried but it looks promising. For example initgraph creates a window, and from this point you can draw into that window using the good old functions, at the end closegraph deletes the window. It also has some more advanced extensions (eg. mouse handling and double buffering).

When I first moved from DOS programming to Windows I didn't have internet, and I begged for something simple like this. But at the end I had to learn how to create windows and how to handle events and use device contexts from the offline help of the Windows SDK.

You need only to write:

GRANT DBA TO NewDBA;

Because this already makes the user a DB Administrator

Configuration worked with Eclipse Mars 4.5 version.

1) Install Eclipse Mars 4.5 from https://eclipse.org/downloads/packages/eclipse-ide-java-ee-developers/mars2 This comes with Tern and embedded Node.js server

2) Install AngularJS Eclipse plugin from Eclipse Marketplace

3) Configure node.js server to the embedded nodejs server within Eclipse (found in the eclipse plugins folder) at Windows-> Preferences -> JavaScript -> Tern -> Server -> node.js. No extra configurations are required.

4) Test configuration in a html or javascript file. https://github.com/angelozerr/angularjs-eclipse

Very easy solution using Console of the browser. You copy this into your browser console and hit enter:

$("div.input div.prompt_container").on('click', function(e){
    $($(e.target).closest('div.input').find('div.input_area')[0]).toggle();
});

Then you toggle the code of the cell simply by clicking on the number of cell input.

Try with cURL request for cross-domain.

If you are working through third party APIs or getting data through CROSS-DOMAIN, it is always recommended to use cURL script (server side) which is more secure.

I always prefer cURL script.

Beware false negatives from the trim() function — it performs a cast-to-string before trimming, and thus will return e.g. "Array" if you pass it an empty array. That may not be an issue, depending on how you process your data, but with the code you supply, a field named question[] could be supplied in the POST data and appear to be a non-empty string. Instead, I would suggest:

$question = $_POST['question'];

if (!is_string || ($question = trim($question))) {
    // Handle error here
}

// If $question was a string, it will have been trimmed by this point

I just want to share my case:

1. if you need play-store library, don't compile all of it, just compile library that you need. example: if you only need maps library instead of compile 'com.google.android.gms:play-services:9.0.2' do this compile 'com.google.android.gms:play-services-maps:9.0.2' on your gradle
2. Dont use OpenJDK for the java, I use java 7 oracle and it works well. if yout need to change default java do this on linux terminal sudo update-alternatives --config java and pick the number

I'm using ubuntu 32bit 4GB RAM. that's all the issue I ever encounter with AS.

I'm going to guess you aren't getting errors or you would've mentioned them. If that's the case, try removing the href attribute value so the page doesn't navigate away before your code is executed. In Angular it's perfectly acceptable to leave href attributes blank.

<a href="" data-router="article" ng-click="changeListName('metro')">

Also I don't know what data-router is doing but if you still aren't getting the proper result, that could be why.

Alternative: Stream.concat()

Stream.concat(map.values().stream(), listContainer.lst.stream())
                             .collect(Collectors.toList()

Try just =COUNTIF(A2:A51,"iPad")

Use onClick with one of the following:

window.location.reload(), i.e.:

<button onClick="window.location.reload();">Refresh Page</button>

Or history.go(0), i.e.:

<button onClick="history.go(0);">Refresh Page</button>

Or window.location.href=window.location.href for 'full' reload, i.e.:

<button onClick="window.location.href=window.location.href">Refresh Page</button>

MDN page on the <button> element.

With regards to @CrazyJugglerDrummer second method it would be:

elementsToChange.style.cursor = "http://wiki-devel.sugarlabs.org/images/e/e2/Arrow.cur";

  if (System.IO.File.Exists(@"C:\Users\Public\DeleteTest\test.txt"))
    {
        // Use a try block to catch IOExceptions, to 
        // handle the case of the file already being 
        // opened by another process. 
        try
        {
            System.IO.File.Delete(@"C:\Users\Public\DeleteTest\test.txt");
        }
        catch (System.IO.IOException e)
        {
            Console.WriteLine(e.Message);
            return;
        }
    }

Any command that takes references as arguments will accept the --all option documented in the man page for git rev-list as follows:

   --all
       Pretend as if all the refs in $GIT_DIR/refs/ are listed on the
       command line as <commit>.

So for instance git log -Sstring --all will display all commits that mention string and that are accessible from a branch or from a tag (I'm assuming that your dangling commits are at least named with a tag).

Keep in mind if you are wanting to test this component you will want to inject the window. Use the @Inject() function to inject the window object by naming it using a string token like detailed in this duplicate

This is a complete procedure to transfer database and logins from an istance to a new one, scripting logins and relocating datafile and log files on the destination. Everything using metascripts.

http://zaboilab.com/sql-server-toolbox/massive-database-migration-between-sql-server-instances-the-complete-procedure

Sorry for the off-site procedure but scripts are very long. You have to:
- Script logins with original SID and HASHED password
- Create script to backup database using metascripts
- Create script to restore database passing relocate parameters using again metascripts
- Run the generated scripts on source and destination instance.
See details and download scripts following the link above.
