With a = subprocess.Popen("cdrecord --help",stdout = subprocess.PIPE) , you need to either use a list or use shell=True;

Either of these will work. The former is preferable.

a = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE)

a = subprocess.Popen('cdrecord --help', shell=True, stdout=subprocess.PIPE)

Also, instead of using Popen.stdout.read/Popen.stderr.read, you should use .communicate() (refer to the subprocess documentation for why).

proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout, stderr = proc.communicate()

See if the below helps you:

I was using the following earlier:

ClientScript.RegisterClientScriptBlock(Page.GetType(), "AlertMsg", "<script language='javascript'>alert('The Web Policy need to be accepted to submit the new assessor information.');</script>");

After implementing AJAX in this page, it stopped working. After reading your blog, I changed the above to:

ScriptManager.RegisterClientScriptBlock(imgBtnSubmit, this.GetType(), "AlertMsg", "<script language='javascript'>alert('The Web Policy need to be accepted to submit the new assessor information.');</script>", false);

This is working perfectly fine.

Clone Temporary Table Structure to New Physical Table in SQL Server

we will see how to Clone Temporary Table Structure to New Physical Table in SQL Server.This is applicable for both Azure SQL db and on-premises.

Demo SQL Script

IF OBJECT_ID('TempDB..#TempTable') IS NOT NULL
    DROP TABLE #TempTable;

SELECT 1 AS ID,'Arul' AS Names
INTO
#TempTable;

SELECT * FROM #TempTable;

METHOD 1

SELECT * INTO TempTable1 FROM #TempTable WHERE 1=0;

EXEC SP_HELP TempTable1;

METHOD 2

SELECT TOP 0 * INTO TempTable1 FROM #TempTable;

EXEC SP_HELP TempTable1;

You can also use:

Get-WmiObject -Class "Win32_computersystem" | Select *

This will show the same result as Format-List * used in the other answers here.

After so many flip-flap I realised that on xml Preview size above,on the left side of Apptheme we have Android Icon with ears click it and change to your target api in case that its not the same as it targeted on built.gradle

Th part of an URI after the # is called "fragment" and is by definition only available/processed on client side (see https://en.wikipedia.org/wiki/Fragment_identifier).

On the client side, this can be accessed using javaScript with window.location.hash.

You can use IPython.display.clear_output to clear the output of a cell.

from IPython.display import clear_output

for i in range(10):
    clear_output(wait=True)
    print("Hello World!")

At the end of this loop you will only see one Hello World!.

Without a code example it's not easy to give you working code. Probably buffering the latest n events is a good strategy. Whenever the buffer changes you can clear the cell's output and print the buffer again.

You can use the ScriptManager.RegisterStartupScript(); to call any of your javascript event/Client Event from the server. For example, to display a message using javascript's alert();, you can do this:

protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
{
Response.write("<script>alert('This is my message');</script>");
 //----or alternatively and to be more proper
 ScriptManager.RegisterStartupScript(this, this.GetType(), "callJSFunction", "alert('This is my message')", true);
}

To be exact for you, do this...

protected void ddl_SelectedIndexChanged(object sender, EventArgs e)
{
 ScriptManager.RegisterStartupScript(this, this.GetType(), "callJSFunction", "CalcTotalAmt();", true);
}

You need to write this in the command prompt:

set HTTP_PROXY=http://your_proxy:your_port

The easiest way to do this is to use jQuery : jQuery UI combobox/autocomplete

if the file is small (slurping):

puts File.read("filename.txt")

if the file is big (streaming):

File.foreach("filename.txt") { |line| puts line }

You're accessing the latitude and longitude incorrectly.

Try

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">

var geocoder = new google.maps.Geocoder();
var address = "new york";

geocoder.geocode( { 'address': address}, function(results, status) {

  if (status == google.maps.GeocoderStatus.OK) {
    var latitude = results[0].geometry.location.lat();
    var longitude = results[0].geometry.location.lng();
    alert(latitude);
  } 
}); 
</script>

I would recommend everyone look into CSS grids. It has been supported by most browsers now since about 2017. Here is a link to some documentation: https://css-tricks.com/snippets/css/complete-guide-grid/ . It is so much easier to keep your page elements where you want them, especially when it comes to responsiveness. It took me all of 20 minutes to learn how to do it, and I'm a newbie!

<div class="grid-div">
    <p class="hello">Hello</p>
    <p class="world">World</p>
</div>


//begin css//

.grid-div {
    display: grid;
    grid-template-columns: 50% 50%;
    grid-template-rows: 50% 50%;
}

.hello {
    grid-column-start: 2;
    grid-row-start: 2;
}

.world {
    grid-column-start: 1;
    grid-row-start: 2;
}

This code will split the page into 4 equal quadrants, placing the "Hello" in the bottom right, and the "World" in the bottom left without having to change their positioning or playing with margins.

This can be extrapolated into very complex grid layouts with overlapping, infinite grids of all sizes, and even grids nested inside grids, without losing control of your elements every time something changes (MS Word I'm looking at you).

Hope this helps whoever still needs it!

Considering the String class' length method returns an int, the maximum length that would be returned by the method would be Integer.MAX_VALUE, which is 2^31 - 1 (or approximately 2 billion.)

In terms of lengths and indexing of arrays, (such as char[], which is probably the way the internal data representation is implemented for Strings), Chapter 10: Arrays of The Java Language Specification, Java SE 7 Edition says the following:

The variables contained in an array have no names; instead they are referenced by array access expressions that use nonnegative integer index values. These variables are called the components of the array. If an array has n components, we say n is the length of the array; the components of the array are referenced using integer indices from 0 to n - 1, inclusive.

Furthermore, the indexing must be by int values, as mentioned in Section 10.4:

Arrays must be indexed by int values;

Therefore, it appears that the limit is indeed 2^31 - 1, as that is the maximum value for a nonnegative int value.

However, there probably are going to be other limitations, such as the maximum allocatable size for an array.

You can set TabLayout position using following functions

public void setTab(){
 tabLayout.setScrollPosition(YOUR_SCROLL_INDEX,0,true);
 tabLayout.setSelected(true);
}

First off, EC2 and Elastic Compute Cloud are the same thing.

Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.

EC2

EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances.

Elastic Beanstalk

Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.

Running Wordpress

For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.

What to pick?

In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.

Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

Show all tags on current HEAD (or commit)

git tag --points-at HEAD

Because if you want to trigger your data with deep of it,you have to pass 3th argument true of your listener.By default it's false and it meens that you function will trigger,only when your variable will change not it's field.

Also, if you want to enforce the List to be read-only (throws a UnsupportedOperationException if modified):

List<String> places = Collections.unmodifiableList(Arrays.asList("One", "Two", "Three"));

Use default method name() as given bellows

public enum Category {
        ONE("one"),
        TWO ("two"),
        THREE("three");

        private final String name;

        Category(String s) {
            name = s;
        }

    }

public class Main {
    public static void main(String[] args) throws Exception {
        System.out.println(Category.ONE.name());
    }
}

If you have no opportunity to change name="submit" you can also submit form this way:

function submitForm(form) {
    const submitFormFunction = Object.getPrototypeOf(form).submit;
    submitFormFunction.call(form);
}

I often need to run an X command on a server that is running many X servers, so the ps based answers do not work. Naturally, $DISPLAY has to be set appropriately. To check that that is valid, use xset q in some fragment like:

if ! xset q &>/dev/null; then
    echo "No X server at \$DISPLAY [$DISPLAY]" >&2
    exit 1
fi

EDIT

Some people find that xset can pause for a annoying amount of time before deciding that $DISPLAY is not pointing at a valid X server (often when tcp/ip is the transport). The fix of course is to use timeout to keep the pause amenable, 1 second say.

if ! timeout 1s xset q &>/dev/null; then
    ?

You can also use chr(176) to print the degree sign. Here is an example using python 3.6.5 interactive shell:

        $('#myModal').on('hidden.bs.modal', function () {
            $(this).removeData('modal');
        });

This one works for me.

Bitmap Resize based on Any Display size

public Bitmap bitmapResize(Bitmap imageBitmap) {

    Bitmap bitmap = imageBitmap;
    float heightbmp = bitmap.getHeight();
    float widthbmp = bitmap.getWidth();

    // Get Screen width
    DisplayMetrics displaymetrics = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
    float height = displaymetrics.heightPixels / 3;
    float width = displaymetrics.widthPixels / 3;

    int convertHeight = (int) hight, convertWidth = (int) width;

    // higher
    if (heightbmp > height) {
        convertHeight = (int) height - 20;
        bitmap = Bitmap.createScaledBitmap(bitmap, convertWidth,
                convertHighet, true);
    }

    // wider
    if (widthbmp > width) {
        convertWidth = (int) width - 20;
        bitmap = Bitmap.createScaledBitmap(bitmap, convertWidth,
                convertHeight, true);
    }

    return bitmap;
}

This is the answer

(CASE
  WHEN
    (isnumeric(ts.TimeInSeconds) = 1) 
  THEN
    CAST(ts.TimeInSeconds AS bigint)
  ELSE
    0
  END) AS seconds

In short:

• OpenJDK has multiple meanings and can refer to:
  • free and open source implementation of the Java Platform, Standard Edition (Java SE)
  • open source repository — the Java source code aka OpenJDK project
  • prebuilt OpenJDK binaries maintained by Oracle
  • prebuilt OpenJDK binaries maintained by the OpenJDK community
• AdoptOpenJDK — prebuilt OpenJDK binaries maintained by community (open source licensed)

Explanation:

Prebuilt OpenJDK (or distribution) — binaries, built from http://hg.openjdk.java.net/, provided as an archive or installer, offered for various platforms, with a possible support contract.

OpenJDK, the source repository (also called OpenJDK project) - is a Mercurial-based open source repository, hosted at http://hg.openjdk.java.net. The Java source code. The vast majority of Java features (from the VM and the core libraries to the compiler) are based solely on this source repository. Oracle have an alternate fork of this.

OpenJDK, the distribution (see the list of providers below) - is free as in beer and kind of free as in speech, but, you do not get to call Oracle if you have problems with it. There is no support contract. Furthermore, Oracle will only release updates to any OpenJDK (the distribution) version if that release is the most recent Java release, including LTS (long-term support) releases. The day Oracle releases OpenJDK (the distribution) version 12.0, even if there's a security issue with OpenJDK (the distribution) version 11.0, Oracle will not release an update for 11.0. Maintained solely by Oracle.

Some OpenJDK projects - such as OpenJDK 8 and OpenJDK 11 - are maintained by the OpenJDK community and provide releases for some OpenJDK versions for some platforms. The community members have taken responsibility for releasing fixes for security vulnerabilities in these OpenJDK versions.

AdoptOpenJDK, the distribution is very similar to Oracle's OpenJDK distribution (in that it is free, and it is a build produced by compiling the sources from the OpenJDK source repository). AdoptOpenJDK as an entity will not be backporting patches, i.e. there won't be an AdoptOpenJDK 'fork/version' that is materially different from upstream (except for some build script patches for things like Win32 support). Meaning, if members of the community (Oracle or others, but not AdoptOpenJDK as an entity) backport security fixes to updates of OpenJDK LTS versions, then AdoptOpenJDK will provide builds for those. Maintained by OpenJDK community.

OracleJDK - is yet another distribution. Starting with JDK12 there will be no free version of OracleJDK. Oracle's JDK distribution offering is intended for commercial support. You pay for this, but then you get to rely on Oracle for support. Unlike Oracle's OpenJDK offering, OracleJDK comes with longer support for LTS versions. As a developer you can get a free license for personal/development use only of this particular JDK, but that's mostly a red herring, as 'just the binary' is basically the same as the OpenJDK binary. I guess it means you can download security-patched versions of LTS JDKs from Oracle's websites as long as you promise not to use them commercially.

Note. It may be best to call the OpenJDK builds by Oracle the "Oracle OpenJDK builds".

Donald Smith, Java product manager at Oracle writes:

Ideally, we would simply refer to all Oracle JDK builds as the "Oracle JDK", either under the GPL or the commercial license, depending on your situation. However, for historical reasons, while the small remaining differences exist, we will refer to them separately as Oracle’s OpenJDK builds and the Oracle JDK.

_{Free Builds from Source - the distribution source code is publicly available and one can assemble its own build}

_{Free Binary Distributions - the distribution binaries are publicly available for download and usage}

_{Extended Updates - aka LTS (long-term support) - Public Updates beyond the 6-month release lifecycle}

_{Commercial Support - some providers offer extended updates and customer support to paying customers, e.g. Oracle JDK (support details)}

_{Permissive License - the distribution license is non-protective, e.g. Apache 2.0}

Which Java Distribution Should I Use?

In the Sun/Oracle days, it was usually Sun/Oracle producing the proprietary downstream JDK distributions based on OpenJDK sources. Recently, Oracle had decided to do their own proprietary builds only with the commercial support attached. They graciously publish the OpenJDK builds as well on their https://jdk.java.net/ site.

What is happening starting JDK 11 is the shift from single-vendor (Oracle) mindset to the mindset where you select a provider that gives you a distribution for the product, under the conditions you like: platforms they build for, frequency and promptness of releases, how support is structured, etc. If you don't trust any of existing vendors, you can even build OpenJDK yourself.

Each build of OpenJDK is usually made from the same original upstream source repository (OpenJDK “the project”). However each build is quite unique - $free or commercial, branded or unbranded, pure or bundled (e.g., BellSoft Liberica JDK offers bundled JavaFX, which was removed from Oracle builds starting JDK 11).

If no environment (e.g., Linux) and/or license requirement defines specific distribution and if you want the most standard JDK build, then probably the best option is to use OpenJDK by Oracle or AdoptOpenJDK.

echo 'Check Time : '.date('H:i:s', $checkTime);
echo '<hr>';

$loginTime = strtotime('09:01:00');
$diff = $checkTime - $loginTime;
echo 'Login Time : '.date('H:i:s', $loginTime).'<br>';
echo ($diff < 0)? 'Late!' : 'Right time!'; echo '<br>';
echo 'Time diff in sec: '.abs($diff);

echo '<hr>';

$loginTime = strtotime('09:00:59');
$diff = $checkTime - $loginTime;
echo 'Login Time : '.date('H:i:s', $loginTime).'<br>';
echo ($diff < 0)? 'Late!' : 'Right time!';

echo '<hr>';

$loginTime = strtotime('09:00:00');
$diff = $checkTime - $loginTime;
echo 'Login Time : '.date('H:i:s', $loginTime).'<br>';
echo ($diff < 0)? 'Late!' : 'Right time!';

I'm late on this, but I was having this issue and what I've learned was that it was an error on my PHP code (in my case the syntax of a select to the db). Usually this error 500 is something to do using syntax - in my experience. In other word: "peopleware" issue! :D

When a folder is created, many Linux filesystems allocate 4096 bytes to store some metadata about the directory itself. This space is increased by a multiple of 4096 bytes as the directory grows.

du command (with or without -b option) take in count this space, as you can see typing:

mkdir test && du -b test

you will have a result of 4096 bytes for an empty dir. So, if you put 2 files of 10000 bytes inside the dir, the total amount given by du -sb would be 24096 bytes.

If you read carefully the question, this is not what asked. The questioner asked:

the sum total of all the data in files and subdirectories I would get if I opened each file and counted the bytes

that in the example above should be 20000 bytes, not 24096.

So, the correct answer IMHO could be a blend of Nelson answer and hlovdal suggestion to handle filenames containing spaces:

find . -type f -print0 | xargs -0 stat --format=%s | awk '{s+=$1} END {print s}'

Following are possible ways to see the version:

Method 1: Connect to the instance of SQL Server, and then run the following query:

Select @@version

An example of the output of this query is as follows:

Microsoft SQL Server 2008 (SP1) - 10.0.2531.0 (X64)   Mar 29 2009 
10:11:52   Copyright (c) 1988-2008 Microsoft Corporation  Express 
Edition (64-bit) on Windows NT 6.1 <X64> (Build 7600: )

Method 2: Connect to the server by using Object Explorer in SQL Server Management Studio. After Object Explorer is connected, it will show the version information in parentheses, together with the user name that is used to connect to the specific instance of SQL Server.

Method 3: Look at the first few lines of the Errorlog file for that instance. By default, the error log is located at Program Files\Microsoft SQL Server\MSSQL.n\MSSQL\LOG\ERRORLOG and ERRORLOG.n files. The entries may resemble the following:

2011-03-27 22:31:33.50 Server      Microsoft SQL Server 2008 (SP1) - 10.0.2531.0 (X64)                 Mar 29 2009 10:11:52                 Copyright (c) 1988-2008 Microsoft Corporation                Express Edition (64-bit) on Windows NT 6.1 <X64> (Build 7600: )

As you can see, this entry gives all the necessary information about the product, such as version, product level, 64-bit versus 32-bit, the edition of SQL Server, and the OS version on which SQL Server is running.

Method 4: Connect to the instance of SQL Server, and then run the following query:

SELECT SERVERPROPERTY('productversion'), SERVERPROPERTY ('productlevel'), SERVERPROPERTY ('edition')

Note This query works with any instance of SQL Server 2000 or of a later version

Also see PEP 263 if you are using a non-ascii characterset

Abstract

This PEP proposes to introduce a syntax to declare the encoding of a Python source file. The encoding information is then used by the Python parser to interpret the file using the given encoding. Most notably this enhances the interpretation of Unicode literals in the source code and makes it possible to write Unicode literals using e.g. UTF-8 directly in an Unicode aware editor.

Problem

In Python 2.1, Unicode literals can only be written using the Latin-1 based encoding "unicode-escape". This makes the programming environment rather unfriendly to Python users who live and work in non-Latin-1 locales such as many of the Asian countries. Programmers can write their 8-bit strings using the favorite encoding, but are bound to the "unicode-escape" encoding for Unicode literals.

Proposed Solution

I propose to make the Python source code encoding both visible and changeable on a per-source file basis by using a special comment at the top of the file to declare the encoding.

To make Python aware of this encoding declaration a number of concept changes are necessary with respect to the handling of Python source code data.

Defining the Encoding

Python will default to ASCII as standard encoding if no other encoding hints are given.

To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as:

      # coding=<encoding name>

or (using formats recognized by popular editors)

      #!/usr/bin/python
      # -*- coding: <encoding name> -*-

or

      #!/usr/bin/python
      # vim: set fileencoding=<encoding name> :

The easiest way according to me will be using SDWebImage

Add this to your pod file

  pod 'SDWebImage', '~> 4.0'

Run pod install

Now import SDWebImage

      import SDWebImage

Now for setting image from url

    imageView.sd_setImage(with: URL(string: "http://www.domain/path/to/image.jpg"), placeholderImage: UIImage(named: "placeholder.png"))

It will show placeholder image but when image is downloaded it will show the image from url .Your app will never crash

This are the main feature of SDWebImage

Categories for UIImageView, UIButton, MKAnnotationView adding web image and cache management

An asynchronous image downloader

An asynchronous memory + disk image caching with automatic cache expiration handling

A background image decompression

A guarantee that the same URL won't be downloaded several times

A guarantee that bogus URLs won't be retried again and again

A guarantee that main thread will never be blocked Performances!

Use GCD and ARC

I have resolve the problem as below 1. Get the tag from your branch 2. Write below command

Example: git branch <Hotfix branch> <TAG>
    git branch hotfix_4.4.3 v4.4.3
    git checkout hotfix_4.4.3

or you can do with other command

git checkout -b <Hotfix branch> <TAG>
-b stands for creating new branch to local 

once you ready with your hotfix branch, It's time to move that branch to github, you can do so by writing below command

git push --set-upstream origin hotfix_4.4.3

I did it in a simple way:

    <a href="http://virtual-doctor.net" onclick="window.open('http://runningrss.com');
return true;">multiopen</a>

It'll open runningrss in a new window and virtual-doctor in same window.

Follow these steps:

1. Create a new branch:

   git branch newfeature
   

2. Checkout new branch: (this will not reset your work.)

   git checkout newfeature
   

3. Now commit your work on this new branch:

   git commit -s
   

Using above steps will keep your original branch clean and you dont have to do any 'git reset --hard'.

A parameter is the variable which is part of the method’s signature (method declaration). An argument is an expression used when calling the method.

Consider the following code:

void Foo(int i, float f)
{
    // Do things
}

void Bar()
{
    int anInt = 1;
    Foo(anInt, 2.0);
}

Here i and f are the parameters, and anInt and 2.0 are the arguments.

Using btoa with unescape and encodeURIComponent didn't work for me. Replacing all the special characters with XML/HTML entities and then converting to the base64 representation was the only way to solve this issue for me. Some code:

base64 = btoa(str.replace(/[\u00A0-\u2666]/g, function(c) {
    return '&#' + c.charCodeAt(0) + ';';
}));

The clear property indicates that the left, right or both sides of an element can not be adjacent to earlier floated elements within the same block formatting context. Cleared elements are pushed below the corresponding floated elements. Examples:

clear: none; Element remains adjacent to floated elements

In my case, the request was getting timed out. So all you need to do is to increase the time out while creating the HttpClient.

HttpClient client = new HttpClient();

client.Timeout = TimeSpan.FromMinutes(5);

You could stil use @TEMP if you quote the identifier "@TEMP":

declare @TEMP table (ID int, Name varchar(max));
insert into @temp SELECT 1 AS ID, 'a' Name;

SELECT * FROM @TEMP WHERE "@TEMP".ID  = 1 ;

The problem could be in the path of the file you want to open. Try and print the path and see if it is fine I had a similar problem

def scrap(soup,filenm):
htm=(soup.prettify().replace("https://","")).replace("http://","")
if ".php" in filenm or ".aspx" in filenm or ".jsp" in filenm:
    filenm=filenm.split("?")[0]
    filenm=("{}.html").format(filenm)
    print("Converted a  file into html that was not compatible")

if ".aspx" in htm:
    htm=htm.replace(".aspx",".aspx.html")
    print("[process]...conversion fron aspx")
if ".jsp" in htm:
    htm=htm.replace(".jsp",".jsp.html")
    print("[process]..conversion from jsp")
if ".php" in htm:
    htm=htm.replace(".php",".php.html")
    print("[process]..conversion from php")

output=open("data/"+filenm,"w",encoding="utf-8")
output.write(htm)
output.close()
print("{} bits of data written".format(len(htm)))

but after adding this code:

nofilenametxt=filenm.split('/')
nofilenametxt=nofilenametxt[len(nofilenametxt)-1]
if (len(nofilenametxt)==0):
    filenm=("{}index.html").format(filenm)

What about a private method that simply looks for the element and determines if it is present like this:

private boolean existsElement(String id) {
    try {
        driver.findElement(By.id(id));
    } catch (NoSuchElementException e) {
        return false;
    }
    return true;
}

This would be quite easy and does the job.

Edit: you could even go further and take a By elementLocator as parameter, eliminating problems if you want to find the element by something other than id.

this is my revisit to this topic, gathering all the information here, plus from other relevant stack overflow questions. It returns images from some provider, while handling out-of-memory conditions and image rotation. It supports gallery, picasa and file managers, like drop box. Usage is simple: as input, the constructor receives the content resolver and the uri. The output is the final bitmap.

/**
 * Creates resized images without exploding memory. Uses the method described in android
 * documentation concerning bitmap allocation, which is to subsample the image to a smaller size,
 * close to some expected size. This is required because the android standard library is unable to
 * create a reduced size image from an image file using memory comparable to the final size (and
 * loading a full sized multi-megapixel picture for processing may exceed application memory budget).

Object.keys(obj) : Array

retrieves all string-valued keys of all enumerable own (non-inherited) properties.

So it gives the same list of keys as you intend by testing each object key with hasOwnProperty. You don't need that extra test operation than and Object.keys( obj ).forEach(function( key ){}) is supposed to be faster. Let's prove it:

var uniqid = function(){_x000D_
   var text = "",_x000D_
     i = 0,_x000D_
     possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";_x000D_
   for( ; i < 32; i++ ) {_x000D_
     text += possible.charAt( Math.floor( Math.random() * possible.length ) );_x000D_
   }_x000D_
   return text;_x000D_
  }, _x000D_
  CYCLES = 100000,_x000D_
  obj = {}, _x000D_
  p1,_x000D_
  p2,_x000D_
  p3,_x000D_
  key;_x000D_
_x000D_
// Populate object with random properties_x000D_
Array.apply( null, Array( CYCLES ) ).forEach(function(){_x000D_
 obj[ uniqid() ] = new Date()_x000D_
});_x000D_
_x000D_
// Approach #1_x000D_
p1 = performance.now();_x000D_
Object.keys( obj ).forEach(function( key ){_x000D_
 var waste = obj[ key ];_x000D_
});_x000D_
_x000D_
p2 = performance.now();_x000D_
console.log( "Object.keys approach took " + (p2 - p1) + " milliseconds.");_x000D_
_x000D_
// Approach #2_x000D_
for( key in obj ) {_x000D_
 if ( obj.hasOwnProperty( key ) ) {_x000D_
  var waste = obj[ key ];_x000D_
 }_x000D_
}_x000D_
_x000D_
p3 = performance.now();_x000D_
console.log( "for...in/hasOwnProperty approach took " + (p3 - p2) + " milliseconds.");

In my Firefox I have following results

• Object.keys approach took 40.21101451665163 milliseconds.
• for...in/hasOwnProperty approach took 98.26163508463651 milliseconds.

PS. on Chrome the difference even bigger http://codepen.io/dsheiko/pen/JdrqXa

PS2: In ES6 (EcmaScript 2015) you can iterate iterable object nicer:

let map = new Map().set('a', 1).set('b', 2);_x000D_
for (let pair of map) {_x000D_
    console.log(pair);_x000D_
}_x000D_
_x000D_
// OR _x000D_
let map = new Map([_x000D_
    [false, 'no'],_x000D_
    [true,  'yes'],_x000D_
]);_x000D_
map.forEach((value, key) => {_x000D_
    console.log(key, value);_x000D_
});

Another post suggests the HTML agility pack:

This is an agile HTML parser that builds a read/write DOM and supports plain XPATH or XSLT (you actually don't HAVE to understand XPATH nor XSLT to use it, don't worry...). It is a .NET code library that allows you to parse "out of the web" HTML files. The parser is very tolerant with "real world" malformed HTML. The object model is very similar to what proposes System.Xml, but for HTML documents (or streams).

In your specific example they are the same, because the optimizer has figured out what you are trying to do is the same in both examples. But it is possible that in non-trivial examples the optimizer may not do this, and in that case there are reasons to prefer one to other on occasion.

NOT IN should be preferred if you are testing multiple rows in your outer select. The subquery inside the NOT IN statement can be evaluated at the beginning of the execution, and the temporary table can be checked against each value in the outer select, rather than re-running the subselect every time as would be required with the NOT EXISTS statement.

If the subquery must be correlated with the outer select, then NOT EXISTS may be preferable, since the optimizer may discover a simplification that prevents the creation of any temporary tables to perform the same function.

You might try passing actual types instead of strings.

import pandas as pd
from datetime import datetime
headers = ['col1', 'col2', 'col3', 'col4'] 
dtypes = [datetime, datetime, str, float] 
pd.read_csv(file, sep='\t', header=None, names=headers, dtype=dtypes)

But it's going to be really hard to diagnose this without any of your data to tinker with.

And really, you probably want pandas to parse the the dates into TimeStamps, so that might be:

pd.read_csv(file, sep='\t', header=None, names=headers, parse_dates=True)

add the -s (silent) option to remove the progress meter, then redirect stderr to stdout to get verbose output on the same fd as the response body

curl -vs google.com 2>&1 | less

Please use this for comparison:

string.Equals(a, b, StringComparison.CurrentCultureIgnoreCase);

If you want to iterate over all the values:

dict.values.forEach { value in
    // print(value)
}

Because computers have finite storage capacity, automatic variables will typically be held in storage elements (whether registers or RAM) that have previously been used for some other arbitrary purpose. If a such a variable is used before a value has been assigned to it, that storage may hold whatever it held previously, and so the contents of the variable will be unpredictable.

As an additional wrinkle, many compilers may keep variables in registers which are larger than the associated types. Although a compiler would be required to ensure that any value which is written to a variable and read back will be truncated and/or sign-extended to its proper size, many compilers will perform such truncation when variables are written and expect that it will have been performed before the variable is read. On such compilers, something like:

uint16_t hey(uint32_t x, uint32_t mode)
{ uint16_t q; 
  if (mode==1) q=2; 
  if (mode==3) q=4; 
  return q; }

 uint32_t wow(uint32_t mode) {
   return hey(1234567, mode);
 }

might very well result in wow() storing the values 1234567 into registers 0 and 1, respectively, and calling foo(). Since x isn't needed within "foo", and since functions are supposed to put their return value into register 0, the compiler may allocate register 0 to q. If mode is 1 or 3, register 0 will be loaded with 2 or 4, respectively, but if it is some other value, the function may return whatever was in register 0 (i.e. the value 1234567) even though that value is not within the range of uint16_t.

To avoid requiring compilers to do extra work to ensure that uninitialized variables never seem to hold values outside their domain, and avoid needing to specify indeterminate behaviors in excessive detail, the Standard says that use of uninitialized automatic variables is Undefined Behavior. In some cases, the consequences of this may be even more surprising than a value being outside the range of its type. For example, given:

void moo(int mode)
{
  if (mode < 5)
    launch_nukes();
  hey(0, mode);      
}

a compiler could infer that because invoking moo() with a mode which is greater than 3 will inevitably lead to the program invoking Undefined Behavior, the compiler may omit any code which would only be relevant if mode is 4 or greater, such as the code which would normally prevent the launch of nukes in such cases. Note that neither the Standard, nor modern compiler philosophy, would care about the fact that the return value from "hey" is ignored--the act of trying to return it gives a compiler unlimited license to generate arbitrary code.

public int getReverseNumber(int number)
{
    int reminder = 0, result = 0;
    while (number !=0)
    {
        if (number >= 10 || number <= -10)
        {
            reminder = number % 10;
            result = result + reminder;
            result = result * 10;
            number = number / 10;
        }
        else
        {
            result = result + number;
            number /= 10;
        }
    }
    return result;

}

// The above code will work for negative numbers also

It's useful in situations where you have hidden internal state such as a cache. For example:

class HashTable
{
...
public:
    string lookup(string key) const
    {
        if(key == lastKey)
            return lastValue;

        string value = lookupInternal(key);

        lastKey = key;
        lastValue = value;

        return value;
    }

private:
    mutable string lastKey, lastValue;
};

And then you can have a const HashTable object still use its lookup() method, which modifies the internal cache.

This is a general solution to your problem. But there is one very important part that the file extension should match your encoding. And of course, that content parameter of downlowadImage function should be base64 encoded string of your image.

const clearUrl = url => url.replace(/^data:image\/\w+;base64,/, '');_x000D_
_x000D_
const downloadImage = (name, content, type) => {_x000D_
  var link = document.createElement('a');_x000D_
  link.style = 'position: fixed; left -10000px;';_x000D_
  link.href = `data:application/octet-stream;base64,${encodeURIComponent(content)}`;_x000D_
  link.download = /\.\w+/.test(name) ? name : `${name}.${type}`;_x000D_
_x000D_
  document.body.appendChild(link);_x000D_
  link.click();_x000D_
  document.body.removeChild(link);_x000D_
}_x000D_
_x000D_
['png', 'jpg', 'gif'].forEach(type => {_x000D_
  var download = document.querySelector(`#${type}`);_x000D_
  download.addEventListener('click', function() {_x000D_
    var img = document.querySelector('#img');_x000D_
_x000D_
    downloadImage('myImage', clearUrl(img.src), type);_x000D_
  });_x000D_
});

This is the method which i used to convert the integer to string.Correct me if i did wrong.

/**
 * @param a
 * @return
 */
private String convertToString(int a) {

    int c;
    char m;
    StringBuilder ans = new StringBuilder();
    // convert the String to int
    while (a > 0) {
        c = a % 10;
        a = a / 10;
        m = (char) ('0' + c);
        ans.append(m);
    }
    return ans.reverse().toString();
}

i have the same problem on ubuntu 15.10. Please try download plugin locally e.g. https://github.com/lmenezes/elasticsearch-kopf/archive/master.zip and install with this command:

sudo /usr/share/elasticsearch/bin/plugin install file:/home/dev/Downloads/elasticsearch-kopf-master.zip

Path maybe different depending on your environment.

Regards.

The solution is way easier.

1. First, you have to locate(in Terminal with "sudo find / -type s") where your mysql.sock file is located. In my case it was in /opt/lampp/var/mysql/mysql.sock
2. Fire up Terminal and issue sudo Nautilus
   This starts your Files manager with super user privileges
3. From Nautilus navigate to where your mysql.sock file is located
4. Right click on the file and select Make Link
5. Rename the Link File to mysqld.sock then Right click on the file and Cut it
6. Go to /var/run and create a folder called mysqld and enter it
7. Now right click and Paste the Link File
8. Voila! You will now have a mysqld.sock file at /var/run/mysqld/mysqld.sock :)

This helped in my case:

Settings -> Apps -> Google Play Store -> Click "Enable" button.

Starting file:

     line 1
   line 2
line 3  
      line 4 

Code:

with open("filename.txt", "r") as f:
    lines = f.readlines()
    for line in lines:
        stripped = line.strip()
        print(stripped)

Output:

line 1
line 2
line 3
line 4

For me work when i change my php.ini in my host:

; Default timeout for socket based streams (seconds)
default_socket_timeout = 300

HTML

<div id="replaceMe">i need to be replaced</div>
<div id="iamReplacement">i am replacement</div>

JavaScript

jQuery('#replaceMe').replaceWith(jQuery('#iamReplacement'));

A variable that shows caps lock state:

let isCapsLockOn = false;

document.addEventListener( 'keydown', function( event ) {
  var caps = event.getModifierState && event.getModifierState( 'CapsLock' );
  if(isCapsLockOn !== caps) isCapsLockOn = caps;
});

document.addEventListener( 'keyup', function( event ) {
  var caps = event.getModifierState && event.getModifierState( 'CapsLock' );
  if(isCapsLockOn !== caps) isCapsLockOn = caps;
});

works on all browsers => canIUse

Another case where it's usually okay is in a reporting database, where data is perhaps already aged and writes just don't happen. In this case, though, the option should be set at the database or table level by the administrator by changing the default isolation level.

In the general case: you can use it when you are very sure that it's okay to read old data. The important thing to remember is that its very easy to get that wrong. For example, even if it's okay at the time you write the query, are you sure something won't change in the database in the future to make these updates more important?

I'll also 2nd the notion that it's probably not a good idea in banking app. Or inventory app. Or anywhere you're thinking about transactions.

You may want to read my prior posting on SO. (Macro'ed version with a temporary ostringstream object.)

For the record: In my own code, I favor snprintf(). With a char array on the local stack, it's not that inefficient. (Well, maybe if you exceeded the array size and looped to do it twice...)

(I've also wrapped it via vsnprintf(). But that costs me some type checking. Yelp if you want the code...)

Most cases where you would need to pass by reference are where you need to return more than one value back to the caller. A "best practice" is to use multiple return values, which is much easier to do in Python than in languages like Java.

Here's a simple example:

def RectToPolar(x, y):
    r = (x ** 2 + y ** 2) ** 0.5
    theta = math.atan2(y, x)
    return r, theta # return 2 things at once

r, theta = RectToPolar(3, 4) # assign 2 things at once

One item that seems to have been missed is star transformations. Index Intersection operators resolve the predicate by calculating the set of rows hit by each of the predicates before any I/O is done on the fact table. On a star schema you would index each individual dimension key and the query optimiser can resolve which rows to select by the index intersection computation. The indexes on individual columns give the best flexibility for this.

If you are using a mac/linux and you want to retrieve local parameters to the machine you're using, this is what you'll do:

1. In terminal run nano ~/.bash_profile
2. add a line like: export MY_VAR=var
3. save & run source ~/.bash_profile
4. in node use like: console.log(process.env.MY_VAR);

Make sure you create Resource and then create method inside it. That was the issue for me. Thanks

You can delete any component by removing all its lines from app.module.ts . Its working fine for me.

The <h:outputLink> renders a fullworthy HTML <a> element with the proper URL in the href attribute which fires a bookmarkable GET request. It cannot directly invoke a managed bean action method.

<h:outputLink value="destination.xhtml">link text</h:outputLink>

The <h:commandLink> renders a HTML <a> element with an onclick script which submits a (hidden) POST form and can invoke a managed bean action method. It's also required to be placed inside a <h:form>.

<h:form>
    <h:commandLink value="link text" action="destination" />
</h:form>

The ?faces-redirect=true parameter on the <h:commandLink>, which triggers a redirect after the POST (as per the Post-Redirect-Get pattern), only improves bookmarkability of the target page when the link is actually clicked (the URL won't be "one behind" anymore), but it doesn't change the href of the <a> element to be a fullworthy URL. It still remains #.

<h:form>
    <h:commandLink value="link text" action="destination?faces-redirect=true" />
</h:form>

Since JSF 2.0, there's also the <h:link> which can take a view ID (a navigation case outcome) instead of an URL. It will generate a HTML <a> element as well with the proper URL in href.

<h:link value="link text" outcome="destination" />

So, if it's for pure and bookmarkable page-to-page navigation like the SO username link, then use <h:outputLink> or <h:link>. That's also better for SEO since bots usually doesn't cipher POST forms nor JS code. Also, UX will be improved as the pages are now bookmarkable and the URL is not "one behind" anymore.

When necessary, you can do the preprocessing job in the constructor or @PostConstruct of a @RequestScoped or @ViewScoped @ManagedBean which is attached to the destination page in question. You can make use of @ManagedProperty or <f:viewParam> to set GET parameters as bean properties.

Here's another way to be compatible with an IHttpActionResult return type. In this case I am asking it to use the XML Serializer(optional) instead of Data Contract serializer, I'm using return ResponseMessage( so that I get a return compatible with IHttpActionResult:

return ResponseMessage(new HttpResponseMessage(HttpStatusCode.OK)
       {
           Content = new ObjectContent<SomeType>(objectToSerialize, 
              new System.Net.Http.Formatting.XmlMediaTypeFormatter { 
                  UseXmlSerializer = true 
              })
       });

You could also do something like:

String str = "a + b - c * d / e < f > g >= h <= i == j";
String[] arr = str.split("(?<=\\G(\\w+(?!\\w+)|==|<=|>=|\\+|/|\\*|-|(<|>)(?!=)))\\s*");

It handles white spaces and words of variable length and produces the array:

[a, +, b, -, c, *, d, /, e, <, f, >, g, >=, h, <=, i, ==, j]

I was getting this error because of the new Google Universal Analytics code, particularly caused by using the Remarketing lists on Analytics.

Here's how I fixed it.
1) Log into Google Analytics
2) Click "Admin" in top menu
3) In "Property" column, click "Property Settings"
4) Make sure "Enable Display Advertiser Features" is "On"
5) Click "Save" at bottom
6) Click ".js Tracking Info" in left menu
7) Click "Tracking Code"
8) Update your website's tracking code


When you run the debugger again, hopefully it will be taken care of.

This question got many answers but none cover the entire process to return clean JSON with everything required to prevent the JSON response to be malformed.

/*
 * returnJsonHttpResponse
 * @param $success: Boolean
 * @param $data: Object or Array
 */
function returnJsonHttpResponse($success, $data)
{
    // remove any string that could create an invalid JSON 
    // such as PHP Notice, Warning, logs...
    ob_clean();

    // this will clean up any previously added headers, to start clean
    header_remove(); 

    // Set the content type to JSON and charset 
    // (charset can be set to something else)
    header("Content-type: application/json; charset=utf-8");

    // Set your HTTP response code, 2xx = SUCCESS, 
    // anything else will be error, refer to HTTP documentation
    if ($success) {
        http_response_code(200);
    } else {
        http_response_code(500);
    }
    
    // encode your PHP Object or Array into a JSON string.
    // stdClass or array
    echo json_encode($data);

    // making sure nothing is added
    exit();
}

Simply put your RecyclerView inside a NestedScrollView. Works perfectly

<android.support.v4.widget.NestedScrollView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="10dp"
                android:layout_marginBottom="25dp">
                <android.support.v7.widget.RecyclerView
                    android:id="@+id/kliste"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" />
            </android.support.v4.widget.NestedScrollView>

We should also take in consideration how the compiler threats the generic classes: in "instantiates" a different type whenever we fill the generic arguments.

Thus we have ListOfAnimal, ListOfDog, ListOfCat, etc, which are distinct classes that end up being "created" by the compiler when we specify the generic arguments. And this is a flat hierarchy (actually regarding to List is not a hierarchy at all).

Another argument why covariance doesn't make sense in case of generic classes is the fact that at base all classes are the same - are List instances. Specialising a List by filling the generic argument doesn't extend the class, it just makes it work for that particular generic argument.

This works fine to me:

<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
     ControlToValidate="YourTextBoxID"
     ErrorMessage="Only numeric allowed." ForeColor="Red"
     ValidationExpression="^[0-9]*$" ValidationGroup="NumericValidate">*
</asp:RegularExpressionValidator>

I think you should add ValidationGroup="NumericValidate" to your submit button also.

We can also use regular expression (/^([\w.-]+)@([\w-]+)((.(\w){2,3})+)$/i) to validate email address format is correct or not.

var emailRegex = new RegExp(/^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$/i);
 var valid = emailRegex.test(emailAddress);
  if (!valid) {
    alert("Invalid e-mail address");
    return false;
  } else
    return true;

I've faked readonly on a radio button by disabling only the un-checked radio buttons. It keeps the user from selecting a different value, and the checked value will always post on submit.

Using jQuery to make readonly:

$(':radio:not(:checked)').attr('disabled', true);

This approach also worked for making a select list readonly, except that you'll need to disable each un-selected option.

The key error generally comes if the key doesn't match any of the dataframe column name 'exactly':

You could also try:

import csv
import pandas as pd
import re
    with open (filename, "r") as file:
        df = pd.read_csv(file, delimiter = ",")
        df.columns = ((df.columns.str).replace("^ ","")).str.replace(" $","")
        print(df.columns)

If you have android, you can install free app on phone (Wifi file Transfer) and enable ssl, port and other options for access and send data in both directions just start application and write in pc browser phone ip and port. enjoy!

Just right click on the file or on the project and click Refresh. The error will vanish. I also faced the same issue and it worked for me.

In this case you're passing props to your thunk. So you can simply call

props.history.push('/cart')

If this isn't the case you can still pass history from your component

export function addProduct(data, history) {
  return dispatch => {
    axios.post('/url', data).then((response) => {
      dispatch({ type: types.AUTH_USER })
      history.push('/cart')
    })
  }
}

You should try it like this:

var result =
        from priceLog in PriceLogList
        group priceLog by priceLog.LogDateTime.ToString("MMM yyyy") into dateGroup
        select new {
            LogDateTime = dateGroup.Key,
            AvgPrice = dateGroup.Average(priceLog => priceLog.Price)
        };

Based on Salman's answer, I've written a small function to encapsulate it:

function sortArrayByLength(arr, ascYN) {
        arr.sort(function (a, b) {           // sort array by length of text
            if (ascYN) return a.length - b.length;              // ASC -> a - b
            else return b.length - a.length;                    // DESC -> b - a
        });
    }

then just call it with

sortArrayByLength( myArray, true );

Note that unfortunately, functions can/should not be added to the Array prototype, as explained on this page.

Also, it modified the array passed as a parameter and doesn't return anything. This would force the duplication of the array and wouldn't be great for large arrays. If someone has a better idea, please do comment!

While the code to create a custom Attribute is fairly simple, it's very important that you understand what attributes are:

Attributes are metadata compiled into your program. Attributes themselves do not add any functionality to a class, property or module - just data. However, using reflection, one can leverage those attributes in order to create functionality.

So, for instance, let's look at the Validation Application Block, from Microsoft's Enterprise Library. If you look at a code example, you'll see:

    /// <summary>
    /// blah blah code.
    /// </summary>
    [DataMember]
    [StringLengthValidator(8, RangeBoundaryType.Inclusive, 8, RangeBoundaryType.Inclusive, MessageTemplate = "\"{1}\" must always have \"{4}\" characters.")]
    public string Code { get; set; }

From the snippet above, one might guess that the code will always be validated, whenever changed, accordingly to the rules of the Validator (in the example, have at least 8 characters and at most 8 characters). But the truth is that the Attribute does nothing; as mentioned previously, it only adds metadata to the property.

However, the Enterprise Library has a Validation.Validate method that will look into your object, and for each property, it'll check if the contents violate the rule informed by the attribute.

So, that's how you should think about attributes -- a way to add data to your code that might be later used by other methods/classes/etc.

What about /usr/share/dict/words on any Unix system? How many words are we talking about? Like OED-Unabridged?

I guess you're using windows 7 with the Orwell Dev CPP

This version of Dev CPP is good for windows 8 only. However on Windows 7 you need the older version of it which is devcpp-4.9.9.2_setup.exe Download it from the link and use it. (Don't forget to uninstall any other version already installed on your pc) Also note that the older version does not work with windows 8.

What you are passing to JSON.parse method must be a valid JSON after removing the wrapping quotes for string.

so something is not a valid JSON but "something" is.

A valid JSON is -

JSON = null
    /* boolean literal */
    or true or false
    /* A JavaScript Number Leading zeroes are prohibited; a decimal point must be followed by at least one digit.*/
    or JSONNumber
    /* Only a limited sets of characters may be escaped; certain control characters are prohibited; the Unicode line separator (U+2028) and paragraph separator (U+2029) characters are permitted; strings must be double-quoted.*/
    or JSONString

    /* Property names must be double-quoted strings; trailing commas are forbidden. */
    or JSONObject
    or JSONArray

Examples -

JSON.parse('{}'); // {}
JSON.parse('true'); // true
JSON.parse('"foo"'); // "foo"
JSON.parse('[1, 5, "false"]'); // [1, 5, "false"]
JSON.parse('null'); // null 
JSON.parse("'foo'"); // error since string should be wrapped by double quotes

You may want to look JSON.

$float = -abs($float);

As others have noted, you can't have immutable arrays in Java.

If you absolutely need a method that returns an array that doesn't influence the original array, then you'd need to clone the array each time:

public int[] getFooArray() {
  return fooArray == null ? null : fooArray.clone();
}

Obviously this is rather expensive (as you'll create a full copy each time you call the getter), but if you can't change the interface (to use a List for example) and can't risk the client changing your internals, then it may be necessary.

This technique is called making a defensive copy.

public ActionResult CreatePerson(int id) //controller 

window.location.href = '@Url.Action("CreatePerson", "Person")?id=' + id;

Or

var id = 'some value';
window.location.href = '@Url.Action("CreatePerson", "Person", new {id = id})';

Another easy alternative:

Since $PWD will usually contain a slash /, use | instead of / for the sed statement:

sed -e "s|xxx|$PWD|"

Change the DNS address of your network to 8.8.8.8 (Google's DNS) or another of your preference:

• Open "System Preferences"
• Click on "Network"
• Select the network which your computer is connected and click on "Advanced"
• Select "DNS", Select the "+" button, type "8.8.8.8" (Google's DNS) or if you prefer OpenDNS, "208.67.222.222"
• Select "Ok" and "Apply"

This error will be gone if you specify the remote that you want to pull like below:

git pull origin master

Note that origin is the name of the remote and master is the branch name.

1) How to check remote's name

git remote -v

2) How to see what branches available in the repository.

git branch -r

Your problem is not actually specific to ejs.

2 things to note here

1. style.css is an external css file. So you dont need style tags inside that file. It should only contain the css.

2. In your express app, you have to mention the public directory from which you are serving the static files. Like css/js/image

it can be done by

app.use(express.static(__dirname + '/public'));

assuming you put the css files in public folder from in your app root. now you have to refer to the css files in your tamplate files, like

<link href="/css/style.css" rel="stylesheet" type="text/css">

Here i assume you have put the css file in css folder inside your public folder.

So folder structure would be

.
./app.js
./public
    /css
        /style.css

You can also try this:

EditText searchTo = (EditText)findViewById(R.id.medittext);
searchTo.addTextChangedListener(new TextWatcher() {
    @Override
    public void afterTextChanged(Editable s) {
        // TODO Auto-generated method stub
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        // TODO Auto-generated method stub
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        doSomething();
    } 
});

As said by Niklas, you need recursion, i.e. you want to define a function to print your dict, and if the value is a dict, you want to call your print function using this new dict.

Something like :

def myprint(d):
    for k, v in d.items():
        if isinstance(v, dict):
            myprint(v)
        else:
            print("{0} : {1}".format(k, v))

Postgresql historically doesn't support procedural code at the command level - only within functions. However, in Postgresql 9, support has been added to execute an inline code block that effectively supports something like this, although the syntax is perhaps a bit odd, and there are many restrictions compared to what you can do with SQL Server. Notably, the inline code block can't return a result set, so can't be used for what you outline above.

In general, if you want to write some procedural code and have it return a result, you need to put it inside a function. For example:

CREATE OR REPLACE FUNCTION somefuncname() RETURNS int LANGUAGE plpgsql AS $$
DECLARE
  one int;
  two int;
BEGIN
  one := 1;
  two := 2;
  RETURN one + two;
END
$$;
SELECT somefuncname();

The PostgreSQL wire protocol doesn't, as far as I know, allow for things like a command returning multiple result sets. So you can't simply map T-SQL batches or stored procedures to PostgreSQL functions.

This is how you link a JS file in HTML

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>

<script> - tag is used to define a client-side script, such as a JavaScript.

type - specify the type of the script

src - script file name and path

docker-compose logs <name-of-service>

From the documentation:

Usage: logs [options] [SERVICE...]

Options:

--no-color Produce monochrome output.

-f, --follow Follow log output.

-t, --timestamps Show timestamps.

--tail="all" Number of lines to show from the end of the logs for each container.

See docker logs

You can start Docker compose in detached mode and attach yourself to the logs of all container later. If you're done watching logs you can detach yourself from the logs output without shutting down your services.

1. Use docker-compose up -d to start all services in detached mode (-d) (you won't see any logs in detached mode)
2. Use docker-compose logs -f -t to attach yourself to the logs of all running services, whereas -f means you follow the log output and the -t option gives you timestamps (See Docker reference)
3. Use Ctrl + z or Ctrl + c to detach yourself from the log output without shutting down your running containers

If you're interested in logs of a single container you can use the docker keyword instead:

1. Use docker logs -t -f <name-of-service>

Save the output

To save the output to a file you add the following to your logs command:

1. docker-compose logs -f -t >> myDockerCompose.log

I had the same issue and basically resolved it by pointing to a specific port number that my MySQL server was running on. Below is the command. Please edit the code to fit your case i.e your port number,your mysql server username,your password.

Use ==:

pip install django_modeltranslation==0.4.0-beta2

This post has helped me a lot, and after a few iterations, this is what we use.

The idea is to post log messages and errors to HTML, for example if you need to debug JS and don't have access to the console.

You do need to change 'console.log' with 'logThis', as it is not recommended to change native functionality.

What you'll get:

• A plain and simple 'logThis' function that will display strings and objects along with current date and time for each line
• A dedicated window on top of everything else. (show it only when needed)
• Can be used inside '.catch' to see relevant errors from promises.
• No change of default console.log behavior
• Messages will appear in the console as well.

function logThis(message) {
  // if we pass an Error object, message.stack will have all the details, otherwise give us a string
  if (typeof message === 'object') {
    message = message.stack || objToString(message);
  }

  console.log(message);

  // create the message line with current time
  var today = new Date();
  var date = today.getFullYear() + '-' + (today.getMonth() + 1) + '-' + today.getDate();
  var time = today.getHours() + ':' + today.getMinutes() + ':' + today.getSeconds();
  var dateTime = date + ' ' + time + ' ';

  //insert line
  document.getElementById('logger').insertAdjacentHTML('afterbegin', dateTime + message + '<br>');
}

function objToString(obj) {
  var str = 'Object: ';
  for (var p in obj) {
    if (obj.hasOwnProperty(p)) {
      str += p + '::' + obj[p] + ',\n';
    }
  }
  return str;
}

const object1 = {
  a: 'somestring',
  b: 42,
  c: false
};

logThis(object1)
logThis('And all the roads we have to walk are winding, And all the lights that lead us there are blinding')

I came across this error on linux environment. If not using headless then you will need

from sys import platform
    if platform != 'win32':

        display.start()

There are two ways to download a file where the HTTP request requires that a header be set.

The credit for the first goes to @guest271314, and credit for the second goes to @dandavis.

The first method is to use the HTML5 File API to create a temporary local file, and the second is to use base64 encoding in conjunction with a data URI.

The solution I used in my project uses the base64 encoding approach for small files, or when the File API is not available, otherwise using the the File API approach.

Solution:

        var id = 123;

        var req = ic.ajax.raw({
            type: 'GET',
            url: '/api/dowloads/'+id,
            beforeSend: function (request) {
                request.setRequestHeader('token', 'token for '+id);
            },
            processData: false
        });

        var maxSizeForBase64 = 1048576; //1024 * 1024

        req.then(
            function resolve(result) {
                var str = result.response;

                var anchor = $('.vcard-hyperlink');
                var windowUrl = window.URL || window.webkitURL;
                if (str.length > maxSizeForBase64 && typeof windowUrl.createObjectURL === 'function') {
                    var blob = new Blob([result.response], { type: 'text/bin' });
                    var url = windowUrl.createObjectURL(blob);
                    anchor.prop('href', url);
                    anchor.prop('download', id+'.bin');
                    anchor.get(0).click();
                    windowUrl.revokeObjectURL(url);
                }
                else {
                    //use base64 encoding when less than set limit or file API is not available
                    anchor.attr({
                        href: 'data:text/plain;base64,'+FormatUtils.utf8toBase64(result.response),
                        download: id+'.bin',
                    });
                    anchor.get(0).click();
                }

            }.bind(this),
            function reject(err) {
                console.log(err);
            }
        );

Note that I'm not using a raw XMLHttpRequest, and instead using ic-ajax, and should be quite similar to a jQuery.ajax solution.

Note also that you should substitute text/bin and .bin with whatever corresponds to the file type being downloaded.

The implementation of FormatUtils.utf8toBase64 can be found here

I was running a PowerShell script into the task scheduller but i forgot to enable the execution-policy to unrestricted, in an elevated PowerShell console:

Set-ExecutionPolicy Unrestricted

After that, the error disappeared (0x1).

None of these worked for me.

My class libraries were definitely all referencing both System.Core and Microsoft.CSharp. Web Application was 4.0 and couldn't upgrade to 4.5 due to support issues.

I was encountering the error compiling a razor template using the Razor Engine, and only encountering it intermittently, like after web application has been restarted.

The solution that worked for me was manually loading the assembly then reattempting the same operation...

        bool retry = true;
        while (retry)
        {
            try
            {
                string textTemplate = File.ReadAllText(templatePath);
                Razor.CompileWithAnonymous(textTemplate, templateFileName);
                retry = false;
            }
            catch (TemplateCompilationException ex)
            {
                LogTemplateException(templatePath, ex);
                retry = false;

                if (ex.Errors.Any(e  => e.ErrorNumber == "CS1969"))
                {
                    try
                    {
                        _logger.InfoFormat("Attempting to manually load the Microsoft.CSharp.RuntimeBinder.Binder");
                        Assembly csharp = Assembly.Load("Microsoft.CSharp, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a");
                        Type type = csharp.GetType("Microsoft.CSharp.RuntimeBinder.Binder");
                        retry = true;
                    }
                    catch(Exception exLoad)
                    {
                        _logger.Error("Failed to manually load runtime binder", exLoad);
                    }
                }

                if (!retry)
                    throw;
            }
        }

Hopefully this might help someone else out there.

In my Angular Bootstrap dropdowns I initialize the JSON Array (vm.zoneDropdown) with ng-init (you can also have ng-init inside the directive template) and I pass the Array in a custom src attribute

<custom-dropdown control-id="zone" label="Zona" model="vm.form.zone" src="vm.zoneDropdown"
                         ng-init="vm.getZoneDropdownSrc()" is-required="true" form="farmaciaForm" css-class="custom-dropdown col-md-3"></custom-dropdown>

Inside the controller:

vm.zoneDropdown = [];
vm.getZoneDropdownSrc = function () {
    vm.zoneDropdown = $customService.getZone();
}

And inside the customDropdown directive template(note that this is only one part of the bootstrap dropdown):

<ul class="uib-dropdown-menu" role="menu" aria-labelledby="btn-append-to-body">
    <li role="menuitem" ng-repeat="dropdownItem in vm.src" ng-click="vm.setValue(dropdownItem)">
        <a ng-click="vm.preventDefault($event)" href="##">{{dropdownItem.text}}</a>
    </li>
</ul>

In JS, "+" concatenation works by creating a new String object.

For example, with...

var s = "Hello";

...we have one object s.

Next:

s = s + " World";

Now, s is a new object.

2nd method: String.prototype.concat

This blog post was helpful for me. I used the "Homebrew built Vim" solution, which in my case saved the new version in /usr/local/bin. At this point, the post suggested hiding the system vim, which didn't work for me, so I used an alias instead.

$ brew install vim
$ alias vim='/path/to/new/vim
$ which vim
vim: aliased to /path/to/new/vim

The easiest way is to simply use the

stmt.setString(position, xml);

methods (for "small" strings which can be easily kept in Java memory), or

try {
  java.sql.Clob clob = 
    oracle.sql.CLOB.createTemporary(
      connection, false, oracle.sql.CLOB.DURATION_SESSION);

  clob.setString(1, xml);
  stmt.setClob(position, clob);
  stmt.execute();
}

// Important!
finally {
  clob.free();
}

If you just want let the user choose image with UIImagePickerController use this code:

import UIKit


class ViewController: UIViewController, UINavigationControllerDelegate, UIImagePickerControllerDelegate {

    @IBOutlet var imageView: UIImageView!
    @IBOutlet var chooseBuuton: UIButton!
    var imagePicker = UIImagePickerController()

    @IBAction func btnClicked() {

        if UIImagePickerController.isSourceTypeAvailable(.savedPhotosAlbum){
            print("Button capture")

            imagePicker.delegate = self
            imagePicker.sourceType = .savedPhotosAlbum
            imagePicker.allowsEditing = false

            present(imagePicker, animated: true, completion: nil)
        }
    }

    func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!){
        self.dismiss(animated: true, completion: { () -> Void in

        })

        imageView.image = image
    }
}

Also, you can use spring annotation RequestMapping above controller class for receveing application/json;utf-8 in all responses

@Controller
@RequestMapping(produces = {"application/json; charset=UTF-8","*/*;charset=UTF-8"})
public class MyController{
 ...
}

There is a shorthand that I use that is not very time efficient, but fits on a single line:

Set<String> h = new HashSet<>(Arrays.asList("a", "b"));

Again, this is not time efficient since you are constructing an array, converting to a list and using that list to create a set.

When initializing static final sets I usually write it like this:

public static final String[] SET_VALUES = new String[] { "a", "b" };
public static final Set<String> MY_SET = new HashSet<>(Arrays.asList(SET_VALUES));

Slightly less ugly and efficiency does not matter for the static initialization.

please take a look at this utils class, may be helpful:

Usage:

<?php
/* first caller */
 Who::callme();

/* list the entire list of calls */
Who::followme();

TCC and TCC/LE from JPSoft are CMD.EXE replacements that add significant functionality. Relevant to the OP's question, which is a builtin command for TCC family command processors.

the fastest way to fill an Array in v8 is:

[...Array(5)].map((_,i) => i);

result will be: [0, 1, 2, 3, 4]

The date should take the format YYYY-MM-DD. Single digit days and months should be padded with a 0. January is 01.

From the documentation:

A string representing a date.

Value: A valid full-date as defined in [RFC 3339], with the additional qualification that the year component is four or more digits representing a number greater than 0.

Your code should be altered to:

<input type="date" value="2013-01-08">

Example jsfiddle

ASCII is in range of 0 to 127, so:

str.replace(/[^\x00-\x7F]/g, "");

bootstrap.yml or bootstrap.properties

It's only used/needed if you're using Spring Cloud and your application's configuration is stored on a remote configuration server (e.g. Spring Cloud Config Server).

From the documentation:

A Spring Cloud application operates by creating a "bootstrap" context, which is a parent context for the main application. Out of the box it is responsible for loading configuration properties from the external sources, and also decrypting properties in the local external configuration files.

Note that the bootstrap.yml or bootstrap.properties can contain additional configuration (e.g. defaults) but generally you only need to put bootstrap config here.

Typically it contains two properties:

• location of the configuration server (spring.cloud.config.uri)
• name of the application (spring.application.name)

Upon startup, Spring Cloud makes an HTTP call to the config server with the name of the application and retrieves back that application's configuration.

application.yml or application.properties

Contains standard application configuration - typically default configuration since any configuration retrieved during the bootstrap process will override configuration defined here.

Not just tab icons, notification and launcher lives an app. I was confused about the sizes of the other icons used for different situations in the app.

I'm using 32px mdpi (Action Bar icons) dimensions and I cannot say if it would be correct.

1. cd ~/.m2
2. git init
3. git commit -am "some comments"
4. cd /path/to/your/project
5. mvn install
6. cd ~/.m2
7. git reset --hard

The following is an algorithm which gives correct but not totally precise since it does not take into account leap year. It also assumes 30 days in a month. A good usage for example is if someone lives in an address from 12/11/2010 to 11/10/2011, it can quickly tells that the person lives there for 10 months and 29 days. From 12/11/2010 to 11/12/2011 is 11 months and 1 day. For certain types of applications, that kind of precision is sufficient. This is for those types of applications because it aims for simplicity:

var datediff = function(start, end) {
  var diff = { years: 0, months: 0, days: 0 };
  var timeDiff = end - start;

  if (timeDiff > 0) {
    diff.years = end.getFullYear() - start.getFullYear();
    diff.months = end.getMonth() - start.getMonth();
    diff.days = end.getDate() - start.getDate();

    if (diff.months < 0) {
      diff.years--;
      diff.months += 12;
    }

    if (diff.days < 0) {
      diff.months = Math.max(0, diff.months - 1);
      diff.days += 30;
    }
  }

  return diff;
};

Unit tests

Took some tooling around but this is what I ended up with.

Generated and installed a certificate on IIS7. Exported as PFX from IIS

Convert to pkcs12

openssl pkcs12 -in certificate.pfx -out certificate.cer -nodes

NOTE: While converting PFX to PEM format, openssl will put all the Certificates and Private Key into a single file. You will need to open the file in Text editor and copy each Certificate & Private key(including the BEGIN/END statements) to its own individual text file and save them as certificate.cer, CAcert.cer, privateKey.key respectively.

-----BEGIN PRIVATE KEY-----
Saved as certificate.key
-----END PRIVATE KEY-----

-----BEGIN CERTIFICATE-----

If selection is not important, it is better to use an ItemsControl wrapped in a ScrollViewer. This combination is more light-weight than the Listbox (which actually is derived from ItemsControl already) and using it would eliminate the need to use a cheap hack to override behavior that is already absent from the ItemsControl.

In cases where the selection behavior IS actually important, then this obviously will not work. However, if you want to change the color of the Selected Item Background in such a way that it is not visible to the user, then that would only serve to confuse them. In cases where your intention is to change some other characteristic to indicate that the item is selected, then some of the other answers to this question may still be more relevant.

Here is a skeleton of how the markup should look:

    <ScrollViewer>
        <ItemsControl>
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    ...
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </ScrollViewer>

=SUMPRODUCT( (MONTH($A$2:$A$6)=1) * ($B$2:$B$6) )

Explanation:

• (MONTH($A$2:$A$6)=1) creates an array of 1 and 0, it's 1 when the month is january, thus in your example the returned array would be [1, 1, 1, 0, 0]

• SUMPRODUCT first multiplies each value of the array created in the above step with values of the array ($B$2:$B$6), then it sums them. Hence in your example it does this: (1 * 430) + (1 * 96) + (1 * 440) + (0 * 72.10) + (0 * 72.30)

This works also in OpenOffice and Google Spreadsheets

Synthesizing from the other responses: pushd is bash-specific and you are make is using another POSIX shell. There is a simple workaround to use separate shell for the part that needs different directory, so just try changing it to:

test -z gen || mkdir -p gen \
 && ( cd $(CURRENT_DIRECTORY)/genscript > /dev/null \
 && perl genmakefile.pl \
 && mv Makefile ../gen/ ) \
 && echo "" > $(CURRENT_DIRECTORY)/gen/SvcGenLog

(I substituted the long path with a variable expansion. I probably is one in the makefile and it clearly expands to the current directory).

Since you are running it from make, I would probably replace the test with a make rule, too. Just

gen/SvcGenLog :
    mkdir -p gen
    cd genscript > /dev/null \
     && perl genmakefile.pl \
     && mv Makefile ../gen/ \
    echo "" > gen/SvcGenLog

(dropped the current directory prefix; you were using relative path at some points anyway) And than just make the rule depend on gen/SvcGenLog. It would be a bit more readable and you can make it depend on the genscript/genmakefile.pl too, so the Makefile in gen will be regenerated if you modify the script. Of course if anything else affects the content of the Makefile, you can make the rule depend on that too.

Instead of explicitly defining the path to the interpreter as in /usr/bin/bash/, by using the env command, the interpreter is searched for and launched from wherever it is first found. This has both upsides and downsides

You can use:

ImageView imgView = new ImageView(this);
InputStream is = getClass().getResourceAsStream("/drawable/" + fileName);
imgView.setImageDrawable(Drawable.createFromStream(is, ""));

void atoh(char *ascii_ptr, char *hex_ptr,int len)
{
    int i;

    for(i = 0; i < (len / 2); i++)
    {

        *(hex_ptr+i)   = (*(ascii_ptr+(2*i)) <= '9') ? ((*(ascii_ptr+(2*i)) - '0') * 16 ) :  (((*(ascii_ptr+(2*i)) - 'A') + 10) << 4);
        *(hex_ptr+i)  |= (*(ascii_ptr+(2*i)+1) <= '9') ? (*(ascii_ptr+(2*i)+1) - '0') :  (*(ascii_ptr+(2*i)+1) - 'A' + 10);

    }


}

I think you want to execute the javascript serverside and not in the browser after post-back, right?

That's not possible as far as I know

If you just want to get it execute after postback, you can do something like this:

this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "xx", "<script>test("+x+","+y+");</script>");

Yes, you can use filter if you know at which position in the tuple the desired column resides. If the case is that the id is the first element of the tuple then you can filter the list like so:

filter(lambda t: t[0]==10, mylist)

This will return the list of corresponding tuples. If you want the age, just pick the element you want. Instead of filter you could also use list comprehension and pick the element in the first go. You could even unpack it right away (if there is only one result):

[age] = [t[1] for t in mylist if t[0]==10]

But I would strongly recommend to use dictionaries or named tuples for this purpose.

As of September of 2015, the most common practice is to use the following CSS:

.sr-only{
    clip: rect(1px, 1px, 1px, 1px);
    height: 1px;
    overflow: hidden;
    position: absolute !important;
    width: 1px;
}

First, we choose stable (not static) data columns to form a Primary Key, precisely because updating Keys in a Relational database (in which the references are by Key) is something we wish to avoid.

1. For this issue, it doesn't matter if the Key is a Relational Key ("made up from the data"), and thus has Relational Integrity, Power, and Speed, or if the "key" is a Record ID, with none of that Relational Integrity, Power, and Speed. The effect is the same.

2. I state this because there are many posts by the clueless ones, who suggest that this is the exact reason that Record IDs are somehow better than Relational Keys.

3. The point is, the Key or Record ID is migrated to wherever a reference is required.

Second, if you have to change the value of the Key or Record ID, well, you have to change it. Here is the OLTP Standard-compliant method. Note that the high-end vendors do not allow "cascade update".

• Write a proc. Foo_UpdateCascade_tr @ID, where Foo is the table name

• Begin a Transaction

• First INSERT-SELECT a new row in the parent table, from the old row, with the new Key or RID value

• Second, for all child tables, working top to bottom, INSERT-SELECT the new rows, from the old rows, with the new Key or RID value

• Third, DELETE the rows in the child tables that have the old Key or RID value, working bottom to top

• Last, DELETE the row in the parent table that has the old Key or RID value

• Commit the Transaction

Re the Other Answers

The other answers are incorrect.

• Disabling constraints and then enabling them, after UPDATing the required rows (parent plus all children) is not something that a person would do in an online production environment, if they wish to remain employed. That advice is good for single-user databases.

• The need to change the value of a Key or RID is not indicative of a design flaw. It is an ordinary need. That is mitigated by choosing stable (not static) Keys. It can be mitigated, but it cannot be eliminated.

• A surrogate substituting a natural Key, will not make any difference. In the example you have given, the "key" is a surrogate. And it needs to be updated.

  • Please, just surrogate, there is no such thing as a "surrogate key", because each word contradicts the other. Either it is a Key (made up from the data) xor it isn't. A surrogate is not made up from the data, it is explicitly non-data. It has none of the properties of a Key.

• There is nothing "tricky" about cascading all the required changes. Refer to the steps given above.

• There is nothing that can be prevented re the universe changing. It changes. Deal with it. And since the database is a collection of facts about the universe, when the universe changes, the database will have to change. That is life in the big city, it is not for new players.

• People getting married and hedgehogs getting buried are not a problem (despite such examples being used to suggest that it is a problem). Because we do not use Names as Keys. We use small, stable Identifiers, such as are used to Identify the data in the universe.

  • Names, descriptions, etc, exist once, in one row. Keys exist wherever they have been migrated. And if the "key" is a RID, then the RID too, exists wherever it has been migrated.

• Don't update the PK! is the second-most hilarious thing I have read in a while. Add a new column is the most.

fade the other in in the callback of fadeout, which runs when fadeout is done. Using your code:

$('#two, #three').hide();
$('.slide').click(function(){
    var $this = $(this);
    $this.fadeOut(function(){ $this.next().fadeIn(); });
});

alternatively, you can just "pause" the chain, but you need to specify for how long:

$(this).fadeOut().next().delay(500).fadeIn();

here is what i put into package.json (running angular 6):

{
  "name": "local-weather-app",
  "version": "1.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve --port 5000",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },

Then a plain npm start will pull in the contents of start. Could also add other options to contents

If searching for an element is important, I'd recommend std::set instead of std::vector. Using this:

std::find(vec.begin(), vec.end(), x) runs in O(n) time, but std::set has its own find() member (ie. myset.find(x)) which runs in O(log n) time - that's much more efficient with large numbers of elements

std::set also guarantees all the added elements are unique, which saves you from having to do anything like if not contained then push_back()....

Short answer - no.

You will only be charged for the time that your instance is up and running, in hour increments. If you are using other services in conjunction you may be charged for those but it would be separate from your server instance.

I had also same issue. I solved this problem by updating my system jdk. Previously i used jdk7.0 and now it is updated to jdk8.0. find below link to download the updated jdk with new version. it help me to solve my problem.

To remove ALL event-handlers, this is what worked for me:

To remove all event handlers mean to have the plain HTML structure without all the event handlers attached to the element and its child nodes. To do this, jQuery's clone() helped.

var original, clone;
// element with id my-div and its child nodes have some event-handlers
original = $('#my-div');
clone = original.clone();
//
original.replaceWith(clone);

With this, we'll have the clone in place of the original with no event-handlers on it.

Good Luck...

alertDialog.setPositiveButton("SAVE",
                new DialogInterface.OnClickListener() {

A function returns one value, but it can "output" any number of values. A sample code:

Function Test (ByVal Input1 As Integer, ByVal Input2 As Integer, _
ByRef Output1 As Integer, ByRef Output2 As Integer) As Integer

  Output1 = Input1 + Input2
  Output2 = Input1 - Input2
  Test = Output1 + Output2

End Function

Sub Test2()

  Dim Ret As Integer, Input1 As Integer, Input2 As Integer, _
  Output1 As integer, Output2 As Integer
  Input1 = 1
  Input2 = 2
  Ret = Test(Input1, Input2, Output1, Output2)
  Sheet1.Range("A1") = Ret     ' 2
  Sheet1.Range("A2") = Output1 ' 3
  Sheet1.Range("A3") = Output2 '-1

End Sub

This is an old question, I know but for 2019 peeps:

Like above if you just want to change the URL you can do this:

<select onChange="window.location.href=this.value">
    <option value="www.google.com">A</option>
    <option value="www.aol.com">B</option>
</select>

But if you want it to act like an a tag and so you can do "./page", "#bottom" or "?a=567" use window.location.replace()

<select onChange="window.location.redirect(this.value)">
    <option value="..">back</option>
    <option value="./list">list</option>
    <option value="#bottom">bottom</option>
</select>

Try this for stored procedures:

SELECT name, create_date, modify_date
FROM sys.objects
WHERE type = 'P'
AND name = 'myProc'

Here is very handy directive angular-datetime. You can use it like this:

<input type="text" datetime="yyyy-MM-dd HH:mm:ss" ng-model="myDate">

It also add mask to your input and perform validation.

You convert the hex string to a byte array.

public static byte[] StringToByteArray(string hex) {
return Enumerable.Range(0, hex.Length)
                 .Where(x => x % 2 == 0)
                 .Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
                 .ToArray();
}

And then use WriteAllBytes to write to the file system.

you can use below event of keypress on document load.

There's an easy way to produce this error:

    $joe = null;
    $joe->anything();

Will render the error:

Fatal error: Call to a member function anything() on a non-object in /Applications/XAMPP/xamppfiles/htdocs/casMail/dao/server.php on line 23

It would be a lot better if PHP would just say,

Fatal error: Call from Joe is not defined because (a) joe is null or (b) joe does not define anything() in on line <##>.

Usually you have build your class so that $joe is not defined in the constructor or

In XML there can be only one root element - you have two - heading and song.

If you restructure to something like:

<?xml version="1.0" encoding="UTF-8"?>
<song> 
 <heading>
 The Twelve Days of Christmas
 </heading>
 ....
</song>

The error about well-formed XML on the root level should disappear (though there may be other issues).

try this:

grep -P '^(tomcat!?)' tst1.txt

It will search for specific word in txt file. Here we are trying to search word tomcat

I think the easiest solution is to set android:animateLayoutChanges="true" to your LinearLayout and then just show/hide view by seting its visibility. Works like a charm, but you have no controll on the animation duration

$(document).ready(function() {
    // do needed things
});

This will trigger once the DOM structure is ready.

You can make cross domain requests using the XMLHttpRequest object. This is done using something called "Cross Origin Resource Sharing". See: http://en.wikipedia.org/wiki/Cross-origin_resource_sharing

Very simply put, when the request is made to the server the server can respond with a Access-Control-Allow-Origin header which will either allow or deny the request. The browser needs to check this header and if it is allowed then it will continue with the request process. If not the browser will cancel the request.

You can find some more information and a working example here: http://www.leggetter.co.uk/2010/03/12/making-cross-domain-javascript-requests-using-xmlhttprequest-or-xdomainrequest.html

JSONP is an alternative solution, but you could argue it's a bit of a hack.

I don't know what all this stuff about calling beginUpdates/endUpdates in succession is, you can just use -[UITableView reloadRowsAtIndexPaths:withAnimation:]. Here is an example project.

System.AppDomain.CurrentDomain.FriendlyName

I've faced this issue several times on MacOS. Git is case sensitive but Mac is only case preserving.

Someone commit a file: Foobar.java and after a few days decides to rename it to FooBar.java. When you pull the latest code it fails with The following untracked working tree files would be overwritten by checkout...

The only reliable way that I've seen that fixes this is:

1. git rm Foobar.java
2. Commit it with a message that you cannot miss git commit -m 'TEMP COMMIT!!'
3. Pull
4. This will pop up a conflict forcing you to merge the conflict - because your change deleted it, but the other change renamed (hence the problem) it
   1. Accept your change which is the 'deletion'
   2. git rebase --continue
5. Now drop your workaround git rebase -i HEAD~2 and drop the TEMP COMMIT!!
6. Confirm that the file is now called FooBar.java

This question is old but I wanted to add an alternative to the accepted answer which didn't exist at the time.

Image Mapster is a jQuery plugin that I wrote to solve some of the shortcomings of Map Hilight (and it was initially an extension of that plugin, though it's since been almost completely rewritten). Initially, this was just the ability to maintain selection state for areas, fix browser compatibility problems. Since its initial release a few months ago, though, I have added a lot of features including the ability to use an alternate image as the source for the highlights.

It also has the ability to identify areas as "masks," meaning you can create areas with "holes", and additionally create complex groupings of areas. For example, area A could cause another area B to be highlighted, but area B itself would not respond to mouse events.

There are a few examples on the web site that show most of the features. The github repository also has more examples and complete documentation.

All package managers have many downsides. You just have to pick which you can live with.

History

npm started out managing node.js modules (that's why packages go into node_modules by default), but it works for the front-end too when combined with Browserify or webpack.

Bower is created solely for the front-end and is optimized with that in mind.

Size of repo

npm is much, much larger than bower, including general purpose JavaScript (like country-data for country information or sorts for sorting functions that is usable on the front end or the back end).

Bower has a much smaller amount of packages.

Handling of styles etc

Bower includes styles etc.

npm is focused on JavaScript. Styles are either downloaded separately or required by something like npm-sass or sass-npm.

Dependency handling

The biggest difference is that npm does nested dependencies (but is flat by default) while Bower requires a flat dependency tree (puts the burden of dependency resolution on the user).

A nested dependency tree means that your dependencies can have their own dependencies which can have their own, and so on. This allows for two modules to require different versions of the same dependency and still work. Note since npm v3, the dependency tree will be flat by default (saving space) and only nest where needed, e.g., if two dependencies need their own version of Underscore.

Some projects use both: they use Bower for front-end packages and npm for developer tools like Yeoman, Grunt, Gulp, JSHint, CoffeeScript, etc.

I think the following is a good exhibit of Echo vs. Write-Host. Notice how test() actually returns an array of ints, not a single int as one could easily be led to believe.

function test {
    Write-Host 123
    echo 456 # AKA 'Write-Output'
    return 789
}

$x = test

Write-Host "x of type '$($x.GetType().name)' = $x"

Write-Host "`$x[0] = $($x[0])"
Write-Host "`$x[1] = $($x[1])"

Terminal output of the above:

123
x of type 'Object[]' = 456 789
$x[0] = 456
$x[1] = 789

You can use the maven help plugin to tell you the contents of your user and global settings files.

mvn help:effective-settings

try this: (create extension method)

public static List<T> ExecuteQuery<T>(this dbContext db, string query) where T : class, new()

tested in .netCore 2.2 and 3.0.

Note: this solution has the slow performance

class LinksParser(HTMLParser.HTMLParser):
  def __init__(self):
    HTMLParser.HTMLParser.__init__(self)
    self.recording = 0
    self.data = []

  def handle_starttag(self, tag, attributes):
    if tag != 'div':
      return
    if self.recording:
      self.recording += 1
      return
    for name, value in attributes:
      if name == 'id' and value == 'remository':
        break
    else:
      return
    self.recording = 1

  def handle_endtag(self, tag):
    if tag == 'div' and self.recording:
      self.recording -= 1

  def handle_data(self, data):
    if self.recording:
      self.data.append(data)

self.recording counts the number of nested div tags starting from a "triggering" one. When we're in the sub-tree rooted in a triggering tag, we accumulate the data in self.data.

The data at the end of the parse are left in self.data (a list of strings, possibly empty if no triggering tag was met). Your code from outside the class can access the list directly from the instance at the end of the parse, or you can add appropriate accessor methods for the purpose, depending on what exactly is your goal.

The class could be easily made a bit more general by using, in lieu of the constant literal strings seen in the code above, 'div', 'id', and 'remository', instance attributes self.tag, self.attname and self.attvalue, set by __init__ from arguments passed to it -- I avoided that cheap generalization step in the code above to avoid obscuring the core points (keep track of a count of nested tags and accumulate data into a list when the recording state is active).

If you are using a webkit browser you can change the color of the caret by following the next CSS snippet. I'm not sure if It's possible to change the format with CSS.

textarea {
    font-size: 24px;
    padding: 10px;
    
    color: red;
    text-shadow: 0px 0px 0px #000;
    -webkit-text-fill-color: transparent;
}

input::-webkit-input-placeholder,
textarea::-webkit-input-placeholder {
    color:
    text-shadow: none;

}

Here is an example: http://jsfiddle.net/8k1k0awb/

Simply Use:

String Uri = request.getRequestURL()+"?"+request.getQueryString();

You are creating a dictionary first, then passing that dictionary to an OrderedDict. For Python versions < 3.6 ^(*), by the time you do that, the ordering is no longer going to be correct. dict is inherently not ordered.

Pass in a sequence of tuples instead:

ship = [("NAME", "Albatross"),
        ("HP", 50),
        ("BLASTERS", 13),
        ("THRUSTERS", 18),
        ("PRICE", 250)]
ship = collections.OrderedDict(ship)

What you see when you print the OrderedDict is it's representation, and it is entirely correct. OrderedDict([('PRICE', 250), ('HP', 50), ('NAME', 'Albatross'), ('BLASTERS', 13), ('THRUSTERS', 18)]) just shows you, in a reproducable representation, what the contents are of the OrderedDict.

^(*): In the CPython 3.6 implementation, the dict type was updated to use a more memory efficient internal structure that has the happy side effect of preserving insertion order, and by extension the code shown in the question works without issues. As of Python 3.7, the Python language specification has been updated to require that all Python implementations must follow this behaviour. See this other answer of mine for details and also why you'd still may want to use an OrderedDict() for certain cases.

If you're more comfortable working inside Excel/VBA, use the open event and test the environment: either have a signal file, a registry entry or an environment variable that controls what the open event does.

You can create the file/setting outside and test inside (use GetEnviromentVariable for env-vars) and test easily. I've written VBScript but the similarities to VBA cause me more angst than ease..

As I understand the problem, you want to use a spreadsheet normally most/some of the time yet have it run in batch and do something extra/different. You can open the sheet from the excel.exe command line but you can't control what it does unless it knows where it is. Using an environment variable is relatively simple and makes testing the spreadsheet easy.

To clarify, use the function below to examine the environment. In a module declare:

Private Declare Function GetEnvVar Lib "kernel32" Alias "GetEnvironmentVariableA" _
    (ByVal lpName As String, ByVal lpBuffer As String, ByVal nSize As Long) As Long

Function GetEnvironmentVariable(var As String) As String
Dim numChars As Long

    GetEnvironmentVariable = String(255, " ")

    numChars = GetEnvVar(var, GetEnvironmentVariable, 255)

End Function

In the Workbook open event (as others):

Private Sub Workbook_Open()
    If GetEnvironmentVariable("InBatch") = "TRUE" Then
        Debug.Print "Batch"
    Else
        Debug.Print "Normal"
    End If
End Sub

Add in active code as applicable. In the batch file, use

set InBatch=TRUE

Storyboard

Create two View Controllers with a button on each. For the second view controller, set the class name to SecondViewController and the storyboard ID to secondVC.

Code

ViewController.swift

import UIKit
class ViewController: UIViewController {

    @IBAction func presentButtonTapped(_ sender: UIButton) {
        
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let myModalViewController = storyboard.instantiateViewController(withIdentifier: "secondVC")
        myModalViewController.modalPresentationStyle = UIModalPresentationStyle.fullScreen
        myModalViewController.modalTransitionStyle = UIModalTransitionStyle.coverVertical
        self.present(myModalViewController, animated: true, completion: nil)
    }
}

SecondViewController.swift

import UIKit
class SecondViewController: UIViewController {
    
    @IBAction func dismissButtonTapped(_ sender: UIButton) {
        self.dismiss(animated: true, completion: nil)
    }
}

The issue of erroneous leftover entries in the .csproj file still occurs with VS2015update3 and can also occur if you try to change the signing certificate for a different one (even if that is one generated using the 'new' option in the certificate selection dropdown). The advice in the accepted answer (mark as not signed, save, unload project, edit .csproj, remove the properties relating to the old certificates/thumbprints/keys & reload project, set certificate) is reliable.

public static string XmlSerializeToString(this object objectInstance)
{
    var serializer = new XmlSerializer(objectInstance.GetType());
    var sb = new StringBuilder();

    using (TextWriter writer = new StringWriter(sb))
    {
        serializer.Serialize(writer, objectInstance);
    }

    return sb.ToString();
}

public static T XmlDeserializeFromString<T>(this string objectData)
{
    return (T)XmlDeserializeFromString(objectData, typeof(T));
}

public static object XmlDeserializeFromString(this string objectData, Type type)
{
    var serializer = new XmlSerializer(type);
    object result;

    using (TextReader reader = new StringReader(objectData))
    {
        result = serializer.Deserialize(reader);
    }

    return result;
}

To use it:

//Make XML
var settings = new ObjectCustomerSettings();
var xmlString = settings.XmlSerializeToString();

//Make Object
var settings = xmlString.XmlDeserializeFromString<ObjectCustomerSettings>(); 

SOLVED

1. Just run CMD as an administrator.
2. Make sure your using the correct truststore password

One more option, not exactly what you asked, but can be useful:

Go to Settings -> Editor -> File and code templates -> Includes tab (on the right). There is a template header for the new files, you can use the username here:

/**
 * @author myname
 */

For system username use:

/**
 * @author ${USER}
 */

You can use the ggjoy package. Let's say that we have three different beta distributions such as:

set.seed(5)
b1<-data.frame(Variant= "Variant 1", Values = rbeta(1000, 101, 1001))
b2<-data.frame(Variant= "Variant 2", Values = rbeta(1000, 111, 1011))
b3<-data.frame(Variant= "Variant 3", Values = rbeta(1000, 11, 101))


df<-rbind(b1,b2,b3)

You can get the three different distributions as follows:

library(tidyverse)
library(ggjoy)


ggplot(df, aes(x=Values, y=Variant))+
    geom_joy(scale = 2, alpha=0.5) +
    scale_y_discrete(expand=c(0.01, 0)) +
    scale_x_continuous(expand=c(0.01, 0)) +
    theme_joy()

just how to replace strings :) as i do first arg will be filename second target string third one the string to be replaced instead of targe

public class ReplaceString{
      public static void main(String[] args)throws Exception {
        if(args.length<3)System.exit(0);
        String targetStr = args[1];
        String altStr = args[2];
        java.io.File file = new java.io.File(args[0]);
        java.util.Scanner scanner = new java.util.Scanner(file);
        StringBuilder buffer = new StringBuilder();
        while(scanner.hasNext()){
          buffer.append(scanner.nextLine().replaceAll(targetStr, altStr));
          if(scanner.hasNext())buffer.append("\n");
        }
        scanner.close();
        java.io.PrintWriter printer = new java.io.PrintWriter(file);
        printer.print(buffer);
        printer.close();
      }
    }

The it++ instruction is done at the end of the block. So if your are erasing the last element, then you try to increment the iterator that is pointing to an empty collection.

Try:

<%= link_to "Add to cart", {:controller => "car", :action => "add_to_cart", :car => car.id }%>

and then in your controller

@car = Car.find(params[:car])

which, will find in your 'cars' table (as with rails pluralization) in your DB a car with id == to car.id

hope it helps! happy coding

How about:

when(a.method(isA(A.class))).thenReturn(b);

or:

when(a.method((A)notNull())).thenReturn(b);

It Works , try out this :

InputStream in_s1 =   TopBrandData.class.getResourceAsStream("/assets/TopBrands.xml");

Nothing is impossible. Here's a solution that simply sets the value of a text input whenever the value of the <select> changes (rendering has been tested on Firefox and Google Chrome):

.select-editable {position:relative; background-color:white; border:solid grey 1px;  width:120px; height:18px;}_x000D_
.select-editable select {position:absolute; top:0px; left:0px; font-size:14px; border:none; width:120px; margin:0;}_x000D_
.select-editable input {position:absolute; top:0px; left:0px; width:100px; padding:1px; font-size:12px; border:none;}_x000D_
.select-editable select:focus, .select-editable input:focus {outline:none;}

<div class="select-editable">_x000D_
  <select onchange="this.nextElementSibling.value=this.value">_x000D_
    <option value=""></option>_x000D_
    <option value="115x175 mm">115x175 mm</option>_x000D_
    <option value="120x160 mm">120x160 mm</option>_x000D_
    <option value="120x287 mm">120x287 mm</option>_x000D_
  </select>_x000D_
  <input type="text" name="format" value=""/>_x000D_
</div>

The next example adds the user input to the empty option slot of the <select> (thanks to @TomerPeled). It also has a little bit more flexible/variable CSS:

.select-editable {position:relative; width:120px;}_x000D_
.select-editable > * {position:absolute; top:0; left:0; box-sizing:border-box; outline:none;}_x000D_
.select-editable select {width:100%;}_x000D_
.select-editable input {width:calc(100% - 20px); margin:1px; border:none; text-overflow:ellipsis;}

<div class="select-editable">_x000D_
  <select onchange="this.nextElementSibling.value=this.value">_x000D_
    <option value=""></option>_x000D_
    <option value="115x175 mm">115x175 mm</option>_x000D_
    <option value="120x160 mm">120x160 mm</option>_x000D_
    <option value="120x287 mm">120x287 mm</option>_x000D_
  </select>_x000D_
  <input type="text" oninput="this.previousElementSibling.options[0].value=this.value; this.previousElementSibling.options[0].innerHTML=this.value" onchange="this.previousElementSibling.selectedIndex=0" value="" />_x000D_
</div>

DataList

In HTML5 you can also do this with the <input> list attribute and <datalist> element:

<input list="browsers" name="browser">_x000D_
<datalist id="browsers">_x000D_
  <option value="Internet Explorer">_x000D_
  <option value="Firefox">_x000D_
  <option value="Chrome">_x000D_
  <option value="Opera">_x000D_
  <option value="Safari">_x000D_
</datalist>_x000D_
(click once to focus and edit, click again to see option dropdown)

But this acts more like an auto-complete list; once you start typing, only the options that contain the typed string are left as suggestions. Depending on what you want to use it for, this may or may not be practical.
