Very old question but it's on top of Google and I don't quite like the answers I see so here's my own.

There's much more to Couchdb than the ability to develop CouchApps. Most people use CouchDb in a classical 3-tiers web architecture.

In practice the deciding factor for most people will be the fact that MongoDb allows ad-hoc querying with a SQL like syntax while CouchDb doesn't (you've got to create map/reduce views which turns some people off even though creating these views is Rapid Application Development friendly - they have nothing to do with stored procedures).

To address points raised in the accepted answer : CouchDb has a great versionning system, but it doesn't mean that it is only suited (or more suited) for places where versionning is important. Also, couchdb is heavy-write friendly thanks to its append-only nature (writes operations return in no time while guaranteeing that no data will ever be lost).

One very important thing that is not mentioned by anyone is the fact that CouchDb relies on b-tree indexes. This means that whether you have 1 "row" or 20 billions, the querying time will always remain below 10ms. This is a game changer which makes CouchDb a low-latency and read-friendly database, and this really shouldn't be overlooked.

To be fair and exhaustive the advantage MongoDb has over CouchDb is tooling and marketing. They have first-class citizen tools for all major languages and platforms making the on-boarding easy and this added to their adhoc querying makes the transition from SQL even easier.

CouchDb doesn't have this level of tooling - even though there are many libraries available today - but CouchDb is exposed as an HTTP API and it is therefore quite easy to create a wrapper in your favorite language to talk with it. I personally like this approach as it avoids bloat and allows you to only take what you want (interface segregation principle).

So I'd say using one or the other is largely a matter of comfort and preference with their paradigms. CouchDb approach "just fits", for certain people, but if after learning about the database features (in the exhaustive official guide) you don't have your "hell yeah" moment, you should probably move on.

I'd discourage using CouchDb if you just want to use "the right tool for the right job". because you'll find out that you can't just use it that way and you'll end up being pissed and writing blog posts such as "Where are joins in CouchDb ?" and "Where is transaction management ?". Indeed Couchdb is - paradoxically - very transparent but at the same time requires a paradigm shift and a change in the way you approach problems to really shine (and really work).

But once you've done that it really pays off. I'd personally need very strong reasons or a major deal breaker on a project to choose another database, but so far I haven't met any.

I don't know anything about MongoDB, but from the CouchDB FAQ:

Is CouchDB Ready for Production?

Yes, see InTheWild for a partial list of projects using CouchDB. Another good overview is CouchDB Case Studies

Also, some links:

• Re: Current CouchDB state?
• SimpleDB, CouchDB and Other "NEW" Data Stores - Feedback

One of the best options is to go for MongoDB(NOSql dB) that supports scalability.Stores large amounts of data nothing but bigdata in the form of documents unlike rows and tables in sql.This is fasters that follows sharding of the data.Uses replicasets to ensure data guarantee that maintains multiple servers having primary db server as the base. Language independent. Flexible to use

One advantage is that you are compiling access into the application, so it cannot accidentally be changed by someone modifying the Web.config.

This may not be an advantage to you, and might be a disadvantage. But for some kinds of access, it may be preferrable.

Plus, I find that authorization information in the Web.config pollutes it, and makes it harder to find things. So in some ways its preference, in others there is no other way to do it.

just indent your code correctly:

def determine_period(universe_array):
    period=0
    tmp=universe_array
    while True:
        tmp=apply_rules(tmp)#aplly_rules is a another function
        period+=1
        if numpy.array_equal(tmp,universe_array) is True:
            return period
        if period>12:  #i wrote this line to stop it..but seems its doesnt work....help..
            return 0
        else:   
            return period

You need to understand that the break statement in your example will exit the infinite loop you've created with while True. So when the break condition is True, the program will quit the infinite loop and continue to the next indented block. Since there is no following block in your code, the function ends and don't return anything. So I've fixed your code by replacing the break statement by a return statement.

Following your idea to use an infinite loop, this is the best way to write it:

def determine_period(universe_array):
    period=0
    tmp=universe_array
    while True:
        tmp=apply_rules(tmp)#aplly_rules is a another function
        period+=1
        if numpy.array_equal(tmp,universe_array) is True:
            break
        if period>12:  #i wrote this line to stop it..but seems its doesnt work....help..
            period = 0
            break

    return period

If you want to know the day of the week for your code to do something with it, DateTime.Now.DayOfWeek will do the job.

If you want to display the day of week to the user, DateTime.Now.ToString("dddd") will give you the localized day name, according to the current culture (MSDN info on the "dddd" format string).

const oneDay = 24 * 60 * 60 * 1000; // hours*minutes*seconds*milliseconds
const firstDate = new Date(2008, 1, 12);
const secondDate = new Date(2008, 1, 22);

const diffDays = Math.round(Math.abs((firstDate - secondDate) / oneDay));

For Laravel ^5

There are many ways by which you can access one controller into another.

class Test1 extends CI_controller
{
    function testfunction(){
        return 1;
    }
}

Then create another class, and include first Class in it, and extend it with your class.

include 'Test1.php';

class Test extends Test1
{
    function myfunction(){
        $this->test();
        echo 1;
    }
}

This is actually javascript but related/relevant because .querySelectorAll targets by CSS syntax:

var i_will_target_self = document.querySelectorAll("ul.menu li a#example")

this example uses css to target links in a menu with id = "example"

that creates a variable which is a collection of the elements we want to change, but we still have actually change them by setting the new target ("_blank"):

for (var i = 0; i < 5; i++) {
i_will_target_self[i].target = "_blank";
}

That code assumes that there are 5 or less elements. That can be changed easily by changing the phrase "i < 5."

you have to add fulltext index on specific fields you want to search.

ALTER TABLE news ADD FULLTEXT(headline, story);

You can create your own custom auth schemas that use the Authorization: header - for example, this is how OAuth works.

As a general rule, if servers or proxies don't understand the values of standard headers, they will leave them alone and ignore them. It is creating your own header keys that can often produce unexpected results - many proxies will strip headers with names they don't recognise.

Having said that, it is possibly a better idea to use cookies to transmit the token, rather than the Authorization: header, for the simple reason that cookies were explicitly designed to carry custom values, whereas the specification for HTTP's built in auth methods does not really say either way - if you want to see exactly what it does say, have a look here.

The other point about this is that many HTTP client libraries have built-in support for Digest and Basic auth but may make life more difficult when trying to set a raw value in the header field, whereas they will all provide easy support for cookies and will allow more or less any value within them.

Hibernate queries are case sensitive with property names (because they end up relying on getter/setter methods on the @Entity).

Make sure you refer to the property as fileName in the Criteria query, not filename.

Specifically, Hibernate will call the getter method of the filename property when executing that Criteria query, so it will look for a method called getFilename(). But the property is called FileName and the getter getFileName().

So, change the projection like so:

criteria.setProjection(Projections.property("fileName"));

break breaks out of a loop, not an if statement, as others have pointed out. The motivation for this isn't too hard to see; think about code like

for item in some_iterable:
    ...
    if break_condition():
        break 

The break would be pretty useless if it terminated the if block rather than terminated the loop -- terminating a loop conditionally is the exact thing break is used for.

There is no show event in js - you need to bind your button either to the click event:

$('#id').on('click', function (e) {

     //your awesome code here

})

Mind that if your button is inside a form, you may prefer to bind the whole form to the submit event.

In your connection string replace server=localhost with "server = Paul-PC\\SQLEXPRESS;"

I really liked this paper for a rule of thumb on separating architecture from design:

http://www.eden-study.org/articles/2006/abstraction-classes-sw-design_ieesw.pdf

It's called the Intension/Locality hypothesis. Statements on the nature of the software that are non-local and intensional are architectural. Statements that are local and intensional are design.

Press the Windows Key and type Windows Features, select the first entry Turn Windows Features On or Off.

Make sure the box next to IIS is checked. You good to go.

You check if it's null in C# like this:

if(MyObject != null) {
  //do something
}

If you want to check against default (tough to understand the question on the info given) check:

if(MyObject != default(MyObject)) {
 //do something
}

I want to add to this thread that it may also have to do with other dependencies.

For instance, nothing I updated or set for NodeJS, MongoDB or Mongoose were the issue - however - connect-mongodb-session had been updated and starting slinging the same error. The solution, in this case, was to simply rollback the version of connect-mongodb-session from version 2.3.0 to 2.2.0.

            return True

    if eachtuple(e, 1, 7) is True:
        print tuple_list.index(e)

It should be noted that the documentation recommends using a Layout rather than Canvas.drawText directly. My full answer about using a StaticLayout is here, but I will provide a summary below.

String text = "This is some text.";

TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);

int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);

Here is a fuller example in the context of a custom view:

public class MyView extends View {

    String mText = "This is some text.";
    TextPaint mTextPaint;
    StaticLayout mStaticLayout;

    // use this constructor if creating MyView programmatically
    public MyView(Context context) {
        super(context);
        initLabelView();
    }

    // this constructor is used when created from xml
    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initLabelView();
    }

    private void initLabelView() {
        mTextPaint = new TextPaint();
        mTextPaint.setAntiAlias(true);
        mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
        mTextPaint.setColor(0xFF000000);

        // default to a single line of text
        int width = (int) mTextPaint.measureText(mText);
        mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);

        // New API alternate
        //
        // StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
        //        .setAlignment(Layout.Alignment.ALIGN_NORMAL)
        //        .setLineSpacing(1, 0) // multiplier, add
        //        .setIncludePad(false);
        // mStaticLayout = builder.build();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // Tell the parent layout how big this view would like to be
        // but still respect any requirements (measure specs) that are passed down.

        // determine the width
        int width;
        int widthMode = MeasureSpec.getMode(widthMeasureSpec);
        int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
        if (widthMode == MeasureSpec.EXACTLY) {
            width = widthRequirement;
        } else {
            width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
            if (widthMode == MeasureSpec.AT_MOST) {
                if (width > widthRequirement) {
                    width = widthRequirement;
                    // too long for a single line so relayout as multiline
                    mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
                }
            }
        }

        // determine the height
        int height;
        int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
        if (heightMode == MeasureSpec.EXACTLY) {
            height = heightRequirement;
        } else {
            height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
            if (heightMode == MeasureSpec.AT_MOST) {
                height = Math.min(height, heightRequirement);
            }
        }

        // Required call: set width and height
        setMeasuredDimension(width, height);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        // do as little as possible inside onDraw to improve performance

        // draw the text on the canvas after adjusting for padding
        canvas.save();
        canvas.translate(getPaddingLeft(), getPaddingTop());
        mStaticLayout.draw(canvas);
        canvas.restore();
    }
}

You can use here String literals

const Angle = ({show}) => {

   const angle = `fa ${show ? 'fa-angle-down' : 'fa-angle-right'}`;

   return <i className={angle} />
}

It sounds like you want a StackPanel where the final element uses up all the remaining space. But why not use a DockPanel? Decorate the other elements in the DockPanel with DockPanel.Dock="Top", and then your help control can fill the remaining space.

XAML:

<DockPanel Width="200" Height="200" Background="PowderBlue">
    <TextBlock DockPanel.Dock="Top">Something</TextBlock>
    <TextBlock DockPanel.Dock="Top">Something else</TextBlock>
    <DockPanel
        HorizontalAlignment="Stretch" 
        VerticalAlignment="Stretch" 
        Height="Auto" 
        Margin="10">

      <GroupBox 
        DockPanel.Dock="Right" 
        Header="Help" 
        Width="100" 
        Background="Beige" 
        VerticalAlignment="Stretch" 
        VerticalContentAlignment="Stretch" 
        Height="Auto">
        <TextBlock Text="This is the help that is available on the news screen." 
                   TextWrapping="Wrap" />
     </GroupBox>

      <StackPanel DockPanel.Dock="Left" Margin="10" 
           Width="Auto" HorizontalAlignment="Stretch">
          <TextBlock Text="Here is the news that should wrap around." 
                     TextWrapping="Wrap"/>
      </StackPanel>
    </DockPanel>
</DockPanel>

If you are on a platform without DockPanel available (e.g. WindowsStore), you can create the same effect with a grid. Here's the above example accomplished using grids instead:

<Grid Width="200" Height="200" Background="PowderBlue">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>
    <StackPanel Grid.Row="0">
        <TextBlock>Something</TextBlock>
        <TextBlock>Something else</TextBlock>
    </StackPanel>
    <Grid Height="Auto" Grid.Row="1" Margin="10">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="100"/>
        </Grid.ColumnDefinitions>
        <GroupBox
            Width="100"
            Height="Auto"
            Grid.Column="1"
            Background="Beige"
            Header="Help">
            <TextBlock Text="This is the help that is available on the news screen." 
              TextWrapping="Wrap"/>
        </GroupBox>
        <StackPanel Width="Auto" Margin="10" DockPanel.Dock="Left">
            <TextBlock Text="Here is the news that should wrap around." 
              TextWrapping="Wrap"/>
        </StackPanel>
    </Grid>
</Grid>

I want to add that there is another difference. It is related to what Andrew posts.

It is also related to a VERY annoying to find bug in our software. See the following simplified example (I also omitted the null check).

public const int SPECIAL_NUMBER = 213;

public bool IsSpecialNumberEntered(string numberTextBoxTextValue)
{
    return numberTextBoxTextValue.Equals(SPECIAL_NUMBER)
}

This will compile and always return false. While the following will give a compile error:

public const int SPECIAL_NUMBER = 213;

public bool IsSpecialNumberEntered(string numberTextBoxTextValue)
{
    return (numberTextBoxTextValue == SPECIAL_NUMBER);
}

We have had to solve a similar problem where someone compared enums of different type using Equals. You are going to read over this MANY times before realising it is the cause of the bug. Especially if the definition of SPECIAL_NUMBER is not near the problem area.

This is why I am really against the use of Equals in situations where is it not necessary. You lose a little bit of type-safety.

May be, it is not the very worst idea to merge (via difftool) from ... yes ... a branch!

> current_branch=$(git status | head -n1 | cut -d' ' -f3)

First off the warning is generated by the variable definition in the source file not the header file. The header can stay pristine and should, since you might be using something like doxygen to generate the API-documentation.

I will assume that you have completely different implementation in source files. In these cases you can either comment out the offending parameter or just write the parameter.

Example:

func(int a, int b)
{
    b;
    foo(a);
}

This might seem cryptic, so defined a macro like UNUSED. The way MFC did it is:

#ifdef _DEBUG
#define UNUSED(x)
#else
#define UNUSED(x) x
#endif

Like this you see the warning still in debug builds, might be helpful.

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

Further to @Penn's comment, and in case the link breaks, you can also achieve this by setting the Default property of the button to True (you can set this in the properties window, open by hitting F4)

That way whenever Return is hit, VBA knows to activate the button's click event. Similarly setting the Cancel property of a button to True would cause that button's click event to run whenever ESC key is hit (useful for gracefully exiting the Userform)

This helped me to call API that was using cookie authentication. I have passed authorization in header like this:

request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));

complete code:

// utility method to read the cookie value:
        public static string ReadCookie(string cookieName)
        {
            var cookies = HttpContext.Current.Request.Cookies;
            var cookie = cookies.Get(cookieName);
            if (cookie != null)
                return cookie.Value;
            return null;
        }

// using statements where you are creating your webclient
using System.Web.Script.Serialization;

var postRequest = new ClassRoom { name = "kushal seth" };

using (var webClient = new WebClient()) {
      JavaScriptSerializer serializer = new JavaScriptSerializer();
      byte[] requestData = Encoding.ASCII.GetBytes(serializer.Serialize(postRequest));
      HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest;
      request.Method = "POST";
      request.ContentType = "application/json";                        
      request.ContentLength = requestData.Length;
      request.ContentType = "application/json";
      request.Expect = "application/json";
      request.Headers.Set("Authorization", Utility.Helper.ReadCookie("AuthCookie"));
      request.GetRequestStream().Write(requestData, 0, requestData.Length);

      using (var response = (HttpWebResponse)request.GetResponse()) {
         var reader = new StreamReader(response.GetResponseStream());
         var objText = reader.ReadToEnd(); // objText will have the value
      }
}

I was having this same issue. I found out if you go to the Task in Task Scheduler that is running the powershell.exe script, you can click "Run whether user is logged on or not" and that will never show the powershell window when the task runs.

This is the jQuery solution that worked for me. offsetWidth etc. didn't work.

function is_overflowing(element, extra_width) {
    return element.position().left + element.width() + extra_width > element.parent().width();
}

If this doesn't work, ensure that elements' parent has the desired width (personally, I had to use parent().parent()). position is relative to the parent. I've also included extra_width because my elements ("tags") contain images which take small time to load, but during the function call they have zero width, spoiling the calculation. To get around that, I use the following calling code:

var extra_width = 0;
$(".tag:visible").each(function() {
    if (!$(this).find("img:visible").width()) {
        // tag image might not be visible at this point,
        // so we add its future width to the overflow calculation
        // the goal is to hide tags that do not fit one line
        extra_width += 28;
    }
    if (is_overflowing($(this), extra_width)) {
        $(this).hide();
    }
});

Hope this helps.

When you use Fabric for public beta releases (signed with prod config), DON'T USE Google Play App Signing. You will must after build two signed apks!

When you distribute to more play stores (samsung, amazon, xiaomi, ...) you will must again build two signed apks.

So be really carefull with Google Play App Signing.

It's not possible to revert it :/ and Google Play did not after accept apks signed with production key. After enable Google Play App Signing only upload key is accepted...

It really complicate CI distribution...

In JavaScript, arrays and collections are different, although they are somewhat similar, but here the react needs an array. You need to create an array from the collection and apply it.

let homeArray = new Array(homes.length);
let i = 0

for (var key in homes) {
    homeArray[i] =  homes[key];
    i = i + 1;
}

A simple regular expression would work

$string = preg_replace("/,$/", "", $string)

You could try this:

SELECT * INTO tbl_NewTableName 
FROM tbl_OldTableName
WHERE Condition1=@Condition1Value

Then run a simple delete:

DELETE FROM tbl_OldTableName
WHERE Condition1=@Condition1Value

Here is a function of getting from now + specified days

import datetime

def get_date(dateFormat="%d-%m-%Y", addDays=0):

    timeNow = datetime.datetime.now()
    if (addDays!=0):
        anotherTime = timeNow + datetime.timedelta(days=addDays)
    else:
        anotherTime = timeNow

    return anotherTime.strftime(dateFormat)

Usage:

addDays = 3 #days
output_format = '%d-%m-%Y'
output = get_date(output_format, addDays)
print output

Swift 5, XCode 11 storyboard way. I think this works for iOS 9 and higher. You want for example "Description" label to get the dynamic height, follow the steps:

1) Select description label -> Go to Attributes Inspector (pencil icon), set: Lines: 0 Line Break: Word Wrap

2) Select your UILabel from storyboard and go to Size Inspector (ruler icon), 3) Go down to "Content Compression Resistance Priority to 1 for all other UIView (lables, buttons, imageview, etc) components that are interacting with your label.

For example, I have UIImageView, Title Label, and Description Label vertically in my view. I set Content Compression Resistance Priority to UIImageView and title label to 1 and for description label to 750. This will make a description label to take as much as needed height.

In the case that you not only want to exclude a list of special characters, but to exclude all characters that are not letters or numbers, I would suggest that you use a char type comparison approach.

For each character in the String, I would check if the unicode character is between "A" and "Z", between "a" and "z" or between "0" and "9". This is the vba code:

Function cleanString(text As String) As String
    Dim output As String
    Dim c 'since char type does not exist in vba, we have to use variant type.
    For i = 1 To Len(text)
        c = Mid(text, i, 1) 'Select the character at the i position
        If (c >= "a" And c <= "z") Or (c >= "0" And c <= "9") Or (c >= "A" And c <= "Z") Then
            output = output & c 'add the character to your output.
        Else
            output = output & " " 'add the replacement character (space) to your output
        End If
    Next
    cleanString = output
End Function

The Wikipedia list of Unicode characers is a good quick-start if you want to customize this function a little more.

This solution has the advantage to be functionnal even if the user finds a way to introduce new special characters. It also faster than comparing two lists together.

First, the class must implements the click listenener :

implements OnItemClickListener

Then set a listener to the ListView

yourList.setOnItemclickListener(this);

And finally, create the clic method:

@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Toast.makeText(MainActivity.this, "You Clicked at ",   
 Toast.LENGTH_SHORT).show();
}

Using OVER() and LIMIT 1:

SELECT COUNT(1) OVER()
FROM posts 
   INNER JOIN votes ON votes.post_id = posts.id 
GROUP BY posts.id
LIMIT 1;

In conclusion, Here give more common way that include return value or void, and throw

import Foundation

extension NSObject {


    func synchronized<T>(lockObj: AnyObject!, closure: () throws -> T) rethrows ->  T
    {
        objc_sync_enter(lockObj)
        defer {
            objc_sync_exit(lockObj)
        }

        return try closure()
    }


}

MarginTop should be marginTop.

I find it really useful when you've got cleanup to do that has to be done even if there's an exception:

try:
    data = something_that_can_go_wrong()
except Exception as e: # yes, I know that's a bad way to do it...
    handle_exception(e)
else:
    do_stuff(data)
finally:
    clean_up()

}
</script><script type="text/javascript" src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>

This is caused by the limited support for the MP4 format within the video tag in Firefox. Support was not added until Firefox 21, and it is still limited to Windows 7 and above. The main reason for the limited support revolves around the royalty fee attached to the mp4 format.

Check out Supported media formats and Media formats supported by the audio and video elements directly from the Mozilla crew or the following blog post for more information:

For example, if you have multiple whereIn OR whereIn conditions and you want to put brackets, do it like this:

$getrecord = DiamondMaster::where('is_delete','0')->where('user_id',Auth::user()->id);
if(!empty($request->stone_id))
{
    $postdata = $request->stone_id;
    $certi_id =trim($postdata,",");
    $getrecord = $getrecord->whereIn('id',explode(",", $certi_id))
                           ->orWhereIn('Certi_NO',explode(",", $certi_id));     
}
$getrecord = $getrecord->get();

Models don't exist in isolation. The structures you'd define for a simulation of cars entering a car park, an embedded system which guides you to a free space, a car parking billing system or for the automated gates/ticket machines usual in car parks are all different.

1. Sessions are not RESTless
2. Do you mean that REST service for http-use only or I got smth wrong? Cookie-based session must be used only for own(!) http-based services! (It could be a problem to work with cookie, e.g. from Mobile/Console/Desktop/etc.)
3. if you provide RESTful service for 3d party developers, never use cookie-based session, use tokens instead to avoid the problems with security.

You can iterate through the key-value pair and write it into file

pair = {'name': name,'location': location}
with open('F:\\twitter.json', 'a') as f:
     f.writelines('{}:{}'.format(k,v) for k, v in pair.items())
     f.write('\n')

Array initializer support for type inference were changed in Visual Basic 10 vs Visual Basic 9.

In previous version of VB it was required to put empty parens to signify an array. Also, it would define the array as object array unless otherwise was stated:

' Integer array
Dim i as Integer() = {1, 2, 3, 4} 

' Object array
Dim o() = {1, 2, 3}

To avoid problems of side effects after changing env, especially using multiple nodes, it is better to set a temporary context.

One safe way to alter the environment is:

 withEnv(['MYTOOL_HOME=/usr/local/mytool']) {
    sh '$MYTOOL_HOME/bin/start'
 }

This approach does not poison the env after the command execution.

I have a ZTE Crescent phone (Orange San Francisco II).

When I connect the phone to the USB a disk shows up in OS X named 'ZTE_USB_Driver'.

Running adb devices displays no connected devices. But after I eject the 'ZTE_USB_Driver' disk from OS X, and run adb devices again the phone shows up as connected.

Just use DataRow.IsNull. It has overrides accepting a column index, a column name, or a DataColumn object as parameters.

Example using the column index:

if (table.rows[0].IsNull(0))
{
    //Whatever I want to do
}

And although the function is called IsNull it really compares with DbNull (which is exactly what you need).

What if I want to check for DbNull but I don't have a DataRow? Use Convert.IsDBNull.

simple answer:

let str = 'this is string, length is >26';_x000D_
_x000D_
console.log([...str]);

You can use "preferred_choices" and "push" the name you want to select to the top of the list. Then it will be selected by default.

'preferred_choices' => array(1), //1 is item number

entity Field Type

curlPost('google.com', [
    'username' => 'admin',
    'password' => '12345',
]);


function curlPost($url, $data) {
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $response = curl_exec($ch);
    $error = curl_error($ch);
    curl_close($ch);
    if ($error !== '') {
        throw new \Exception($error);
    }

    return $response;
}

You can use a table and apply a width attribute to the first <td>.

Code:

<table>
    <tr>
        <td width="100">Content1</td>
        <td>Content2</td>
    </tr>
    <tr>
        <td>Content3</td>
        <td>Content4</td>
    </tr>
</table>

Result

Content1       Content2
Content3       Content4

Maven always checks your local repository first, however,your dependency needs to be installed in your repo for maven to find it.

Run mvn install in your dependency module first, and then build your dependent module.

For good performance, combine answers from aznilamir and from FrustratedWithFormsDesigner

private static final String BLANKS = "                       ";
private static String getBlankLine( int length )
{
    if( length <= BLANKS.length() )
    {
        return BLANKS.substring( 0, length );
    }
    else
    {
        char[] array = new char[ length ];
        Arrays.fill( array, ' ' );
        return new String( array );
    }
}

Adjust size of BLANKS depending on your requirements. My specific BLANKS string is about 200 characters length.

This expands on a previous answer. The best solution I've found is to make an innocuous CSS attribute that only appears if a CSS3 media query is met, and then have the JS test for that attribute.

So for instance, in the CSS you'd have:

@media screen only and (orientation:landscape)
{
    //  Some innocuous rule here
    body
    {
        background-color: #fffffe;
    }
}
@media screen only and (orientation:portrait)
{
    //  Some innocuous rule here
    body
    {
        background-color: #fffeff;
    }
}

You then go to JavaScript (I'm using jQuery for funsies). Color declarations may be weird, so you may want to use something else, but this is the most foolproof method I've found for testing it. You can then just use the resize event to pick up on switching. Put it all together for:

function detectOrientation(){
    //  Referencing the CSS rules here.
    //  Change your attributes and values to match what you have set up.
    var bodyColor = $("body").css("background-color");
    if (bodyColor == "#fffffe") {
        return "landscape";
    } else
    if (bodyColor == "#fffeff") {
        return "portrait";
    }
}
$(document).ready(function(){
    var orientation = detectOrientation();
    alert("Your orientation is " + orientation + "!");
    $(document).resize(function(){
        orientation = detectOrientation();
        alert("Your orientation is " + orientation + "!");
    });
});

The best part of this is that as of my writing this answer, it doesn't appear to have any effect on desktop interfaces, since they (generally) don't (seem to) pass any argument for orientation to the page.

The URL is relative to the location of the CSS file, so this should work for you:

url('../../images/image.jpg')

The relative URL goes two folders back, and then to the images folder - it should work for both cases, as long as the structure is the same.

From https://www.w3.org/TR/CSS1/#url:

Partial URLs are interpreted relative to the source of the style sheet, not relative to the document

When creating the AlertDialog you can set a theme to use.

Example - Creating the Dialog

AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.MyAlertDialogStyle);
builder.setTitle("AppCompatDialog");
builder.setMessage("Lorem ipsum dolor...");
builder.setPositiveButton("OK", null);
builder.setNegativeButton("Cancel", null);
builder.show();

styles.xml - Custom style

<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <!-- Used for the buttons -->
    <item name="colorAccent">#FFC107</item>
    <!-- Used for the title and text -->
    <item name="android:textColorPrimary">#FFFFFF</item>
    <!-- Used for the background -->
    <item name="android:background">#4CAF50</item>
</style>

Result

Edit

In order to change the Appearance of the Title, you can do the following. First add a new style:

<style name="MyTitleTextStyle">
    <item name="android:textColor">#FFEB3B</item>
    <item name="android:textAppearance">@style/TextAppearance.AppCompat.Title</item>
</style>

afterwards simply reference this style in your MyAlertDialogStyle:

<style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    ...
    <item name="android:windowTitleStyle">@style/MyTitleTextStyle</item>
</style>

This way you can define a different textColor for the message via android:textColorPrimary and a different for the title via the style.

The PHP.net recommended way of setting the charset is now this:

mysqli_set_charset('utf8')

Try with :

echo "To: [email protected]" > /var/www/report.csv
echo "Subject: Subject" >> /var/www/report.csv
echo "MIME-Version: 1.0" >> /var/www/report.csv
echo "Content-Type: text/html; charset=\"us-ascii\"" >> /var/www/report.csv
echo "Content-Disposition: inline" >> /var/www/report.csv

echo "<html>" >> /var/www/report.csv
mysql -u ***** -p***** -H -e "select * from users LIMIT 20" dev >> /var/www/report.csv
echo "</html>" >> /var/www/report.csv

mail -s "Built notification" [email protected] < /var/www/report.csv

I'm using a slightly different approach where public struct methods implement interfaces but their logic is limited to just wrapping private (unexported) functions which take those interfaces as parameters. This gives you the granularity you would need to mock virtually any dependency and yet have a clean API to use from outside your test suite.

To understand this it is imperative to understand that you have access to the unexported methods in your test case (i.e. from within your _test.go files) so you test those instead of testing the exported ones which have no logic inside beside wrapping.

To summarize: test the unexported functions instead of testing the exported ones!

Let's make an example. Say that we have a Slack API struct which has two methods:

• the SendMessage method which sends an HTTP request to a Slack webhook
• the SendDataSynchronously method which given a slice of strings iterates over them and calls SendMessage for every iteration

So in order to test SendDataSynchronously without making an HTTP request each time we would have to mock SendMessage, right?

package main

import (
    "fmt"
)

// URI interface
type URI interface {
    GetURL() string
}

// MessageSender interface
type MessageSender interface {
    SendMessage(message string) error
}

// This one is the "object" that our users will call to use this package functionalities
type API struct {
    baseURL  string
    endpoint string
}

// Here we make API implement implicitly the URI interface
func (api *API) GetURL() string {
    return api.baseURL + api.endpoint
}

// Here we make API implement implicitly the MessageSender interface
// Again we're just WRAPPING the sendMessage function here, nothing fancy 
func (api *API) SendMessage(message string) error {
    return sendMessage(api, message)
}

// We want to test this method but it calls SendMessage which makes a real HTTP request!
// Again we're just WRAPPING the sendDataSynchronously function here, nothing fancy
func (api *API) SendDataSynchronously(data []string) error {
    return sendDataSynchronously(api, data)
}

// this would make a real HTTP request
func sendMessage(uri URI, message string) error {
    fmt.Println("This function won't get called because we will mock it")
    return nil
}

// this is the function we want to test :)
func sendDataSynchronously(sender MessageSender, data []string) error {
    for _, text := range data {
        err := sender.SendMessage(text)

        if err != nil {
            return err
        }
    }

    return nil
}

// TEST CASE BELOW

// Here's our mock which just contains some variables that will be filled for running assertions on them later on
type mockedSender struct {
    err      error
    messages []string
}

// We make our mock implement the MessageSender interface so we can test sendDataSynchronously
func (sender *mockedSender) SendMessage(message string) error {
    // let's store all received messages for later assertions
    sender.messages = append(sender.messages, message)

    return sender.err // return error for later assertions
}

func TestSendsAllMessagesSynchronously() {
    mockedMessages := make([]string, 0)
    sender := mockedSender{nil, mockedMessages}

    messagesToSend := []string{"one", "two", "three"}
    err := sendDataSynchronously(&sender, messagesToSend)

    if err == nil {
        fmt.Println("All good here we expect the error to be nil:", err)
    }

    expectedMessages := fmt.Sprintf("%v", messagesToSend)
    actualMessages := fmt.Sprintf("%v", sender.messages)

    if expectedMessages == actualMessages {
        fmt.Println("Actual messages are as expected:", actualMessages)
    }
}

func main() {
    TestSendsAllMessagesSynchronously()
}

What I like about this approach is that by looking at the unexported methods you can clearly see what the dependencies are. At the same time the API that you export is a lot cleaner and with less parameters to pass along since the true dependency here is just the parent receiver which is implementing all those interfaces itself. Yet every function is potentially depending only on one part of it (one, maybe two interfaces) which makes refactors a lot easier. It's nice to see how your code is really coupled just by looking at the functions signatures, I think it makes a powerful tool against smelling code.

To make things easy I put everything into one file to allow you to run the code in the playground here but I suggest you also check out the full example on GitHub, here is the slack.go file and here the slack_test.go.

And here the whole thing.

This code is "the least amount of code", but not the best practice:

try
{
    return ObjectA.PropertyA.PropertyB.PropertyC;
}
catch(NullReferenceException)
{
     return null;
}

I'll explain the main use cases of implicits below, but for more detail see the relevant chapter of Programming in Scala.

Implicit parameters

The final parameter list on a method can be marked implicit, which means the values will be taken from the context in which they are called. If there is no implicit value of the right type in scope, it will not compile. Since the implicit value must resolve to a single value and to avoid clashes, it's a good idea to make the type specific to its purpose, e.g. don't require your methods to find an implicit Int!

example:

  // probably in a library
class Prefixer(val prefix: String)
def addPrefix(s: String)(implicit p: Prefixer) = p.prefix + s

  // then probably in your application
implicit val myImplicitPrefixer = new Prefixer("***")
addPrefix("abc")  // returns "***abc"

Implicit conversions

When the compiler finds an expression of the wrong type for the context, it will look for an implicit Function value of a type that will allow it to typecheck. So if an A is required and it finds a B, it will look for an implicit value of type B => A in scope (it also checks some other places like in the B and A companion objects, if they exist). Since defs can be "eta-expanded" into Function objects, an implicit def xyz(arg: B): A will do as well.

So the difference between your methods is that the one marked implicit will be inserted for you by the compiler when a Double is found but an Int is required.

implicit def doubleToInt(d: Double) = d.toInt
val x: Int = 42.0

will work the same as

def doubleToInt(d: Double) = d.toInt
val x: Int = doubleToInt(42.0)

In the second we've inserted the conversion manually; in the first the compiler did the same automatically. The conversion is required because of the type annotation on the left hand side.

Regarding your first snippet from Play:

Actions are explained on this page from the Play documentation (see also API docs). You are using

apply(block: (Request[AnyContent]) ? Result): Action[AnyContent]

on the Action object (which is the companion to the trait of the same name).

So we need to supply a Function as the argument, which can be written as a literal in the form

request => ...

In a function literal, the part before the => is a value declaration, and can be marked implicit if you want, just like in any other val declaration. Here, request doesn't have to be marked implicit for this to type check, but by doing so it will be available as an implicit value for any methods that might need it within the function (and of course, it can be used explicitly as well). In this particular case, this has been done because the bindFromRequest method on the Form class requires an implicit Request argument.

First access the children with: this.props.children, each child will then have its ref as a property on it.

PATH=echo $PATH | sed 's/:/\n/g' | sort -u | sed ':a;N;$!ba;s/\n/:/g'

You can also use the special word like:

Public Sub Search()
  If "My Big String with, in the middle" Like "*,*" Then
    Debug.Print ("Found ','")
  End If
End Sub

First declare a class that will return later:

public void date()
{
    Datetime startdate;
    Datetime enddate;
    Timespan remaindate;

    startdate = DateTime.Parse(txtstartdate.Text).Date;
    enddate = DateTime.Parse(txtenddate.Text).Date;

    remaindate = enddate - startdate;

    if (remaindate != null)
    {
        lblmsg.Text = "you have left with " + remaindate.TotalDays + "days.";
    }
    else
    {
        lblmsg.Text = "correct your code again.";
    }
}

protected void btncal_Click(object sender, EventArgs e)
{
    date();
}

Use a button control to call the above class. Here is an example:

There is no easy way to animate hiding/showing views. You can try method described in following answer: How do I animate View.setVisibility(GONE)

Just paste this into your line of codes:

<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

you can use awk, for example, cut off 1st,2nd and last 3 columns

awk '{for(i=3;i<=NF-3;i++} print $i}' file

if you have a programing language such as Ruby (1.9+)

$ ruby -F"\t" -ane 'print $F[2..-3].join("\t")' file

You can use ref.

import ChildForm from './components/ChildForm'

new Vue({
  el: '#app',
  data: {
    item: {}
  },
  template: `
  <div>
     <ChildForm :item="item" ref="form" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.$refs.form.submit()
    }
  },
  components: { ChildForm },
})

If you dislike tight coupling, you can use Event Bus as shown by @Yosvel Quintero. Below is another example of using event bus by passing in the bus as props.

import ChildForm from './components/ChildForm'

new Vue({
  el: '#app',
  data: {
    item: {},
    bus: new Vue(),
  },
  template: `
  <div>
     <ChildForm :item="item" :bus="bus" ref="form" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.bus.$emit('submit')
    }
  },
  components: { ChildForm },
})

Code of component.

<template>

If you run docker run <NAME> it will spawn a new image, which most likely isn't what you want.

If you want to change a current image do the following:

docker ps -a

Take the id of your target container and go to:

cd /var/lib/docker/containers/<conainerID><and then some:)>

Stop the container:

docker stop <NAME>

Change the files

vi config.v2.json

"Config": {
    ....
    "ExposedPorts": {
        "80/tcp": {},
        "8888/tcp": {}
    },
    ....
},
"NetworkSettings": {
....
"Ports": {
     "80/tcp": [
         {
             "HostIp": "",
             "HostPort": "80"
         }
     ],

And change file

vi hostconfig.json

"PortBindings": {
     "80/tcp": [
         {
             "HostIp": "",
             "HostPort": "80"
         }
     ],
     "8888/tcp": [
         {
             "HostIp": "",
             "HostPort": "8888"
         } 
     ]
 }

Restart your docker and it should work.

You are applying the formatting to the workbook that has the code, not the added workbook. You'll want to get in the habit of fully qualifying sheet and range references. The code below does that and works for me in Excel 2010:

Set wb = Workbooks.Add
With wb.Sheets(1)
    .Range("A1") = "Acctdate"
    .Range("B1") = "Ledger"
    .Range("C1") = "CY"
    .Range("D1") = "BusinessUnit"
    .Range("E1") = "OperatingUnit"
    .Range("F1") = "LOB"
    .Range("G1") = "Account"

    .Range("A2", "A50000").Value = Me.TextBox3.Value
    .Range("A2", "A50000").NumberFormat = "yyyy-mm-dd"

John Conde does all the right procedures in his method but doesn't satisfy the final step in your question which is to format the result to your specifications.

This code (Demo) will display the raw difference, expose the trouble with trying to immediately format the raw difference, display my preparation steps, and finally present the correctly formatted result:

$datetime1 = new DateTime('2017-04-26 18:13:06');
$datetime2 = new DateTime('2011-01-17 17:13:00');  // change the millenium to see output difference
$diff = $datetime1->diff($datetime2);

// this will get you very close, but it will not pad the digits to conform with your expected format
echo "Raw Difference: ",$diff->format('%y years %m months %d days %h hours %i minutes %s seconds'),"\n";

// Notice the impact when you change $datetime2's millenium from '1' to '2'
echo "Invalid format: ",$diff->format('%Y-%m-%d %H:%i:%s'),"\n";  // only H does it right

$details=array_intersect_key((array)$diff,array_flip(['y','m','d','h','i','s']));

echo '$detail array: ';
var_export($details);
echo "\n";

array_map(function($v,$k)
    use(&$r)
    {
        $r.=($k=='y'?str_pad($v,4,"0",STR_PAD_LEFT):str_pad($v,2,"0",STR_PAD_LEFT));
        if($k=='y' || $k=='m'){$r.="-";}
        elseif($k=='d'){$r.=" ";}
        elseif($k=='h' || $k=='i'){$r.=":";}
    },$details,array_keys($details)
);
echo "Valid format: ",$r; // now all components of datetime are properly padded

Output:

Raw Difference: 6 years 3 months 9 days 1 hours 0 minutes 6 seconds
Invalid format: 06-3-9 01:0:6
$detail array: array (
  'y' => 6,
  'm' => 3,
  'd' => 9,
  'h' => 1,
  'i' => 0,
  's' => 6,
)
Valid format: 0006-03-09 01:00:06

Now to explain my datetime value preparation:

$details takes the diff object and casts it as an array. array_flip(['y','m','d','h','i','s']) creates an array of keys which will be used to remove all irrelevant keys from (array)$diff using array_intersect_key().

Then using array_map() my method iterates each value and key in $details, pads its left side to the appropriate length with 0's, and concatenates the $r (result) string with the necessary separators to conform with requested datetime format.

I found that the only option that worked for me was

font-size:0;

I was also using overflow and white-space: nowrap; float: left; seems to mess things up

I just wrote a quick plugin to run a test using your same snippet and it works fine

$.fn.test = function() {
      return this.each(function(){
        var new_id = 5;
        $(this).attr('id',   this.id + '_' + new_id);
        $(this).attr('name', this.name + '_' + new_id);
        $(this).attr('value', 'test');
      });
    };

$(document).ready(function() {
    $('#field_id').test()
});

<body>
  <div id="container">

  <input type="text" name="field_name" id="field_id" value="meh" />
  </div>
</body>

So I can only presume something else is going on in your code. Can you provide some more details?

$source = "number35"

$number=$null

$result = foreach ($_ in $source.ToCharArray()){$digit="0123456789".IndexOf($\_,0);if($digit -ne -1){$number +=$\_}}[int32]$number

Just feed it digits and it wil convert to an Int32

Using list comprehension:

>>> lst = [['a','b','c'], [1,2,3], ['x','y','z']]
>>> lst2 = [item[0] for item in lst]
>>> lst2
['a', 1, 'x']

"all" option does not work anymore, The new parameter is;

x = pd.merge(df1, df2, how="outer")

Welcome to the wonderful world of portability... or rather the lack of it. Before we start analyzing these two options in detail and take a deeper look how different operating systems handle them, it should be noted that the BSD socket implementation is the mother of all socket implementations. Basically all other systems copied the BSD socket implementation at some point in time (or at least its interfaces) and then started evolving it on their own. Of course the BSD socket implementation was evolved as well at the same time and thus systems that copied it later got features that were lacking in systems that copied it earlier. Understanding the BSD socket implementation is the key to understanding all other socket implementations, so you should read about it even if you don't care to ever write code for a BSD system.

There are a couple of basics you should know before we look at these two options. A TCP/UDP connection is identified by a tuple of five values:

{<protocol>, <src addr>, <src port>, <dest addr>, <dest port>}

Any unique combination of these values identifies a connection. As a result, no two connections can have the same five values, otherwise the system would not be able to distinguish these connections any longer.

The protocol of a socket is set when a socket is created with the socket() function. The source address and port are set with the bind() function. The destination address and port are set with the connect() function. Since UDP is a connectionless protocol, UDP sockets can be used without connecting them. Yet it is allowed to connect them and in some cases very advantageous for your code and general application design. In connectionless mode, UDP sockets that were not explicitly bound when data is sent over them for the first time are usually automatically bound by the system, as an unbound UDP socket cannot receive any (reply) data. Same is true for an unbound TCP socket, it is automatically bound before it will be connected.

If you explicitly bind a socket, it is possible to bind it to port 0, which means "any port". Since a socket cannot really be bound to all existing ports, the system will have to choose a specific port itself in that case (usually from a predefined, OS specific range of source ports). A similar wildcard exists for the source address, which can be "any address" (0.0.0.0 in case of IPv4 and :: in case of IPv6). Unlike in case of ports, a socket can really be bound to "any address" which means "all source IP addresses of all local interfaces". If the socket is connected later on, the system has to choose a specific source IP address, since a socket cannot be connected and at the same time be bound to any local IP address. Depending on the destination address and the content of the routing table, the system will pick an appropriate source address and replace the "any" binding with a binding to the chosen source IP address.

By default, no two sockets can be bound to the same combination of source address and source port. As long as the source port is different, the source address is actually irrelevant. Binding socketA to ipA:portA and socketB to ipB:portB is always possible if ipA != ipB holds true, even when portA == portB. E.g. socketA belongs to a FTP server program and is bound to 192.168.0.1:21 and socketB belongs to another FTP server program and is bound to 10.0.0.1:21, both bindings will succeed. Keep in mind, though, that a socket may be locally bound to "any address". If a socket is bound to 0.0.0.0:21, it is bound to all existing local addresses at the same time and in that case no other socket can be bound to port 21, regardless which specific IP address it tries to bind to, as 0.0.0.0 conflicts with all existing local IP addresses.

Anything said so far is pretty much equal for all major operating system. Things start to get OS specific when address reuse comes into play. We start with BSD, since as I said above, it is the mother of all socket implementations.

BSD

SO_REUSEADDR

If SO_REUSEADDR is enabled on a socket prior to binding it, the socket can be successfully bound unless there is a conflict with another socket bound to exactly the same combination of source address and port. Now you may wonder how is that any different than before? The keyword is "exactly". SO_REUSEADDR mainly changes the way how wildcard addresses ("any IP address") are treated when searching for conflicts.

Without SO_REUSEADDR, binding socketA to 0.0.0.0:21 and then binding socketB to 192.168.0.1:21 will fail (with error EADDRINUSE), since 0.0.0.0 means "any local IP address", thus all local IP addresses are considered in use by this socket and this includes 192.168.0.1, too. With SO_REUSEADDR it will succeed, since 0.0.0.0 and 192.168.0.1 are not exactly the same address, one is a wildcard for all local addresses and the other one is a very specific local address. Note that the statement above is true regardless in which order socketA and socketB are bound; without SO_REUSEADDR it will always fail, with SO_REUSEADDR it will always succeed.

To give you a better overview, let's make a table here and list all possible combinations:

SO_REUSEADDR       socketA        socketB       Result
---------------------------------------------------------------------
  ON/OFF       192.168.0.1:21   192.168.0.1:21    Error (EADDRINUSE)
  ON/OFF       192.168.0.1:21      10.0.0.1:21    OK
  ON/OFF          10.0.0.1:21   192.168.0.1:21    OK
   OFF             0.0.0.0:21   192.168.1.0:21    Error (EADDRINUSE)
   OFF         192.168.1.0:21       0.0.0.0:21    Error (EADDRINUSE)
   ON              0.0.0.0:21   192.168.1.0:21    OK
   ON          192.168.1.0:21       0.0.0.0:21    OK
  ON/OFF           0.0.0.0:21       0.0.0.0:21    Error (EADDRINUSE)

The table above assumes that socketA has already been successfully bound to the address given for socketA, then socketB is created, either gets SO_REUSEADDR set or not, and finally is bound to the address given for socketB. Result is the result of the bind operation for socketB. If the first column says ON/OFF, the value of SO_REUSEADDR is irrelevant to the result.

Okay, SO_REUSEADDR has an effect on wildcard addresses, good to know. Yet that isn't it's only effect it has. There is another well known effect which is also the reason why most people use SO_REUSEADDR in server programs in the first place. For the other important use of this option we have to take a deeper look on how the TCP protocol works.

A socket has a send buffer and if a call to the send() function succeeds, it does not mean that the requested data has actually really been sent out, it only means the data has been added to the send buffer. For UDP sockets, the data is usually sent pretty soon, if not immediately, but for TCP sockets, there can be a relatively long delay between adding data to the send buffer and having the TCP implementation really send that data. As a result, when you close a TCP socket, there may still be pending data in the send buffer, which has not been sent yet but your code considers it as sent, since the send() call succeeded. If the TCP implementation was closing the socket immediately on your request, all of this data would be lost and your code wouldn't even know about that. TCP is said to be a reliable protocol and losing data just like that is not very reliable. That's why a socket that still has data to send will go into a state called TIME_WAIT when you close it. In that state it will wait until all pending data has been successfully sent or until a timeout is hit, in which case the socket is closed forcefully.

At most, the amount of time the kernel will wait before it closes the socket, regardless if it still has data in flight or not, is called the Linger Time. The Linger Time is globally configurable on most systems and by default rather long (two minutes is a common value you will find on many systems). It is also configurable per socket using the socket option SO_LINGER which can be used to make the timeout shorter or longer, and even to disable it completely. Disabling it completely is a very bad idea, though, since closing a TCP socket gracefully is a slightly complex process and involves sending forth and back a couple of packets (as well as resending those packets in case they got lost) and this whole close process is also limited by the Linger Time. If you disable lingering, your socket may not only lose data in flight, it is also always closed forcefully instead of gracefully, which is usually not recommended. The details about how a TCP connection is closed gracefully are beyond the scope of this answer, if you want to learn more about, I recommend you have a look at this page. And even if you disabled lingering with SO_LINGER, if your process dies without explicitly closing the socket, BSD (and possibly other systems) will linger nonetheless, ignoring what you have configured. This will happen for example if your code just calls exit() (pretty common for tiny, simple server programs) or the process is killed by a signal (which includes the possibility that it simply crashes because of an illegal memory access). So there is nothing you can do to make sure a socket will never linger under all circumstances.

The question is, how does the system treat a socket in state TIME_WAIT? If SO_REUSEADDR is not set, a socket in state TIME_WAIT is considered to still be bound to the source address and port and any attempt to bind a new socket to the same address and port will fail until the socket has really been closed, which may take as long as the configured Linger Time. So don't expect that you can rebind the source address of a socket immediately after closing it. In most cases this will fail. However, if SO_REUSEADDR is set for the socket you are trying to bind, another socket bound to the same address and port in state TIME_WAIT is simply ignored, after all its already "half dead", and your socket can bind to exactly the same address without any problem. In that case it plays no role that the other socket may have exactly the same address and port. Note that binding a socket to exactly the same address and port as a dying socket in TIME_WAIT state can have unexpected, and usually undesired, side effects in case the other socket is still "at work", but that is beyond the scope of this answer and fortunately those side effects are rather rare in practice.

There is one final thing you should know about SO_REUSEADDR. Everything written above will work as long as the socket you want to bind to has address reuse enabled. It is not necessary that the other socket, the one which is already bound or is in a TIME_WAIT state, also had this flag set when it was bound. The code that decides if the bind will succeed or fail only inspects the SO_REUSEADDR flag of the socket fed into the bind() call, for all other sockets inspected, this flag is not even looked at.

SO_REUSEPORT

SO_REUSEPORT is what most people would expect SO_REUSEADDR to be. Basically, SO_REUSEPORT allows you to bind an arbitrary number of sockets to exactly the same source address and port as long as all prior bound sockets also had SO_REUSEPORT set before they were bound. If the first socket that is bound to an address and port does not have SO_REUSEPORT set, no other socket can be bound to exactly the same address and port, regardless if this other socket has SO_REUSEPORT set or not, until the first socket releases its binding again. Unlike in case of SO_REUESADDR the code handling SO_REUSEPORT will not only verify that the currently bound socket has SO_REUSEPORT set but it will also verify that the socket with a conflicting address and port had SO_REUSEPORT set when it was bound.

SO_REUSEPORT does not imply SO_REUSEADDR. This means if a socket did not have SO_REUSEPORT set when it was bound and another socket has SO_REUSEPORT set when it is bound to exactly the same address and port, the bind fails, which is expected, but it also fails if the other socket is already dying and is in TIME_WAIT state. To be able to bind a socket to the same addresses and port as another socket in TIME_WAIT state requires either SO_REUSEADDR to be set on that socket or SO_REUSEPORT must have been set on both sockets prior to binding them. Of course it is allowed to set both, SO_REUSEPORT and SO_REUSEADDR, on a socket.

There is not much more to say about SO_REUSEPORT other than that it was added later than SO_REUSEADDR, that's why you will not find it in many socket implementations of other systems, which "forked" the BSD code before this option was added, and that there was no way to bind two sockets to exactly the same socket address in BSD prior to this option.

Connect() Returning EADDRINUSE?

Most people know that bind() may fail with the error EADDRINUSE, however, when you start playing around with address reuse, you may run into the strange situation that connect() fails with that error as well. How can this be? How can a remote address, after all that's what connect adds to a socket, be already in use? Connecting multiple sockets to exactly the same remote address has never been a problem before, so what's going wrong here?

As I said on the very top of my reply, a connection is defined by a tuple of five values, remember? And I also said, that these five values must be unique otherwise the system cannot distinguish two connections any longer, right? Well, with address reuse, you can bind two sockets of the same protocol to the same source address and port. That means three of those five values are already the same for these two sockets. If you now try to connect both of these sockets also to the same destination address and port, you would create two connected sockets, whose tuples are absolutely identical. This cannot work, at least not for TCP connections (UDP connections are no real connections anyway). If data arrived for either one of the two connections, the system could not tell which connection the data belongs to. At least the destination address or destination port must be different for either connection, so that the system has no problem to identify to which connection incoming data belongs to.

So if you bind two sockets of the same protocol to the same source address and port and try to connect them both to the same destination address and port, connect() will actually fail with the error EADDRINUSE for the second socket you try to connect, which means that a socket with an identical tuple of five values is already connected.

Multicast Addresses

Most people ignore the fact that multicast addresses exist, but they do exist. While unicast addresses are used for one-to-one communication, multicast addresses are used for one-to-many communication. Most people got aware of multicast addresses when they learned about IPv6 but multicast addresses also existed in IPv4, even though this feature was never widely used on the public Internet.

The meaning of SO_REUSEADDR changes for multicast addresses as it allows multiple sockets to be bound to exactly the same combination of source multicast address and port. In other words, for multicast addresses SO_REUSEADDR behaves exactly as SO_REUSEPORT for unicast addresses. Actually, the code treats SO_REUSEADDR and SO_REUSEPORT identically for multicast addresses, that means you could say that SO_REUSEADDR implies SO_REUSEPORT for all multicast addresses and the other way round.

FreeBSD/OpenBSD/NetBSD

All these are rather late forks of the original BSD code, that's why they all three offer the same options as BSD and they also behave the same way as in BSD.

macOS (MacOS X)

At its core, macOS is simply a BSD-style UNIX named "Darwin", based on a rather late fork of the BSD code (BSD 4.3), which was then later on even re-synchronized with the (at that time current) FreeBSD 5 code base for the Mac OS 10.3 release, so that Apple could gain full POSIX compliance (macOS is POSIX certified). Despite having a microkernel at its core ("Mach"), the rest of the kernel ("XNU") is basically just a BSD kernel, and that's why macOS offers the same options as BSD and they also behave the same way as in BSD.

iOS / watchOS / tvOS

iOS is just a macOS fork with a slightly modified and trimmed kernel, somewhat stripped down user space toolset and a slightly different default framework set. watchOS and tvOS are iOS forks, that are stripped down even further (especially watchOS). To my best knowledge they all behave exactly as macOS does.

Linux

Linux < 3.9

Prior to Linux 3.9, only the option SO_REUSEADDR existed. This option behaves generally the same as in BSD with two important exceptions:

1. As long as a listening (server) TCP socket is bound to a specific port, the SO_REUSEADDR option is entirely ignored for all sockets targeting that port. Binding a second socket to the same port is only possible if it was also possible in BSD without having SO_REUSEADDR set. E.g. you cannot bind to a wildcard address and then to a more specific one or the other way round, both is possible in BSD if you set SO_REUSEADDR. What you can do is you can bind to the same port and two different non-wildcard addresses, as that's always allowed. In this aspect Linux is more restrictive than BSD.

2. The second exception is that for client sockets, this option behaves exactly like SO_REUSEPORT in BSD, as long as both had this flag set before they were bound. The reason for allowing that was simply that it is important to be able to bind multiple sockets to exactly to the same UDP socket address for various protocols and as there used to be no SO_REUSEPORT prior to 3.9, the behavior of SO_REUSEADDR was altered accordingly to fill that gap. In that aspect Linux is less restrictive than BSD.

Linux >= 3.9

Linux 3.9 added the option SO_REUSEPORT to Linux as well. This option behaves exactly like the option in BSD and allows binding to exactly the same address and port number as long as all sockets have this option set prior to binding them.

Yet, there are still two differences to SO_REUSEPORT on other systems:

1. To prevent "port hijacking", there is one special limitation: All sockets that want to share the same address and port combination must belong to processes that share the same effective user ID! So one user cannot "steal" ports of another user. This is some special magic to somewhat compensate for the missing SO_EXCLBIND/SO_EXCLUSIVEADDRUSE flags.

2. Additionally the kernel performs some "special magic" for SO_REUSEPORT sockets that isn't found in other operating systems: For UDP sockets, it tries to distribute datagrams evenly, for TCP listening sockets, it tries to distribute incoming connect requests (those accepted by calling accept()) evenly across all the sockets that share the same address and port combination. Thus an application can easily open the same port in multiple child processes and then use SO_REUSEPORT to get a very inexpensive load balancing.

Android

Even though the whole Android system is somewhat different from most Linux distributions, at its core works a slightly modified Linux kernel, thus everything that applies to Linux should apply to Android as well.

Windows

Windows only knows the SO_REUSEADDR option, there is no SO_REUSEPORT. Setting SO_REUSEADDR on a socket in Windows behaves like setting SO_REUSEPORT and SO_REUSEADDR on a socket in BSD, with one exception:

Prior to Windows 2003, a socket with SO_REUSEADDR could always been bound to exactly the same source address and port as an already bound socket, even if the other socket did not have this option set when it was bound. This behavior allowed an application "to steal" the connected port of another application. Needless to say that this has major security implications!

Microsoft realized that and added another important socket option: SO_EXCLUSIVEADDRUSE. Setting SO_EXCLUSIVEADDRUSE on a socket makes sure that if the binding succeeds, the combination of source address and port is owned exclusively by this socket and no other socket can bind to them, not even if it has SO_REUSEADDR set.

This default behavior was changed first in Windows 2003, Microsoft calls that "Enhanced Socket Security" (funny name for a behavior that is default on all other major operating systems). For more details just visit this page. There are three tables: The first one shows the classic behavior (still in use when using compatibility modes!), the second one shows the behavior of Windows 2003 and up when the bind() calls are made by the same user, and the third one when the bind() calls are made by different users.

Solaris

Solaris is the successor of SunOS. SunOS was originally based on a fork of BSD, SunOS 5 and later was based on a fork of SVR4, however SVR4 is a merge of BSD, System V, and Xenix, so up to some degree Solaris is also a BSD fork, and a rather early one. As a result Solaris only knows SO_REUSEADDR, there is no SO_REUSEPORT. The SO_REUSEADDR behaves pretty much the same as it does in BSD. As far as I know there is no way to get the same behavior as SO_REUSEPORT in Solaris, that means it is not possible to bind two sockets to exactly the same address and port.

Similar to Windows, Solaris has an option to give a socket an exclusive binding. This option is named SO_EXCLBIND. If this option is set on a socket prior to binding it, setting SO_REUSEADDR on another socket has no effect if the two sockets are tested for an address conflict. E.g. if socketA is bound to a wildcard address and socketB has SO_REUSEADDR enabled and is bound to a non-wildcard address and the same port as socketA, this bind will normally succeed, unless socketA had SO_EXCLBIND enabled, in which case it will fail regardless the SO_REUSEADDR flag of socketB.

Other Systems

In case your system is not listed above, I wrote a little test program that you can use to find out how your system handles these two options. Also if you think my results are wrong, please first run that program before posting any comments and possibly making false claims.

All that the code requires to build is a bit POSIX API (for the network parts) and a C99 compiler (actually most non-C99 compiler will work as well as long as they offer inttypes.h and stdbool.h; e.g. gcc supported both long before offering full C99 support).

All that the program needs to run is that at least one interface in your system (other than the local interface) has an IP address assigned and that a default route is set which uses that interface. The program will gather that IP address and use it as the second "specific address".

It tests all possible combinations you can think of:

• TCP and UDP protocol
• Normal sockets, listen (server) sockets, multicast sockets
• SO_REUSEADDR set on socket1, socket2, or both sockets
• SO_REUSEPORT set on socket1, socket2, or both sockets
• All address combinations you can make out of 0.0.0.0 (wildcard), 127.0.0.1 (specific address), and the second specific address found at your primary interface (for multicast it's just 224.1.2.3 in all tests)

and prints the results in a nice table. It will also work on systems that don't know SO_REUSEPORT, in which case this option is simply not tested.

What the program cannot easily test is how SO_REUSEADDR acts on sockets in TIME_WAIT state as it's very tricky to force and keep a socket in that state. Fortunately most operating systems seems to simply behave like BSD here and most of the time programmers can simply ignore the existence of that state.

Here's the code (I cannot include it here, answers have a size limit and the code would push this reply over the limit).

If you do not want to block things and also not want to use multi threading, here is the solution for you: https://msdn.microsoft.com/en-us/library/system.timers.timer(v=vs.110).aspx

The UI Thread is not blocked and the timer waits for 2 seconds before doing something.

Here is the code coming from the link above:

        // Create a timer with a two second interval.
    aTimer = new System.Timers.Timer(2000);
    // Hook up the Elapsed event for the timer. 
    aTimer.Elapsed += OnTimedEvent;
    aTimer.Enabled = true;

    Console.WriteLine("Press the Enter key to exit the program... ");
    Console.ReadLine();
    Console.WriteLine("Terminating the application...");

The accepted answer is through but there is official explanation on this:

The WebApplicationContext is an extension of the plain ApplicationContext that has some extra features necessary for web applications. It differs from a normal ApplicationContext in that it is capable of resolving themes (see Using themes), and that it knows which Servlet it is associated with (by having a link to the ServletContext). The WebApplicationContext is bound in the ServletContext, and by using static methods on the RequestContextUtils class you can always look up the WebApplicationContext if you need access to it.

Cited from Spring web framework reference

By the way servlet and root context are both webApplicationContext:

Moving the file from which you are importing to an outside directory helps.
This is extra useful when your main file makes any other files in its own directory.
Ex:
Before:
Project
|---dir1
|-------main.py
|-------module1.py
After:
Project
|---module1.py
|---dir1
|-------main.py

LINQ in .NET 4.0 has another option for you; the .Any() method;

string[] values = new[] { "1", "2", "3" };
string data = "some string 1";
bool containsAny = values.Any(data.Contains);

• Refresh your tables.
• Restart the SQL server.
• Look out for the spelling mistakes in Query.

The reason why your current approach doesn't work is because Jackson is used by default to serialize and to deserialize objects. However, it doesn't know how to serialize the JSONObject. If you want to create a dynamic JSON structure, you can use a Map, for example:

@GetMapping
public Map<String, String> sayHello() {
    HashMap<String, String> map = new HashMap<>();
    map.put("key", "value");
    map.put("foo", "bar");
    map.put("aa", "bb");
    return map;
}

This will lead to the following JSON response:

{ "key": "value", "foo": "bar", "aa": "bb" }

This is a bit limited, since it may become a bit more difficult to add child objects. Jackson has its own mechanism though, using ObjectNode and ArrayNode. To use it, you have to autowire ObjectMapper in your service/controller. Then you can use:

@GetMapping
public ObjectNode sayHello() {
    ObjectNode objectNode = mapper.createObjectNode();
    objectNode.put("key", "value");
    objectNode.put("foo", "bar");
    objectNode.put("number", 42);
    return objectNode;
}

This approach allows you to add child objects, arrays, and use all various types.

I am also faced the same issue

use this code:

// notice string() call
String resStr = response.body().string();    
JSONObject json = new JSONObject(resStr);

it definitely works

If you are using Ruby 1.9.2 or later, you can use URI.encode_www_form if you don't need arrays.

E.g. (from the Ruby docs in 1.9.3):

URI.encode_www_form([["q", "ruby"], ["lang", "en"]])
#=> "q=ruby&lang=en"
URI.encode_www_form("q" => "ruby", "lang" => "en")
#=> "q=ruby&lang=en"
URI.encode_www_form("q" => ["ruby", "perl"], "lang" => "en")
#=> "q=ruby&q=perl&lang=en"
URI.encode_www_form([["q", "ruby"], ["q", "perl"], ["lang", "en"]])
#=> "q=ruby&q=perl&lang=en"

You'll notice that array values are not set with key names containing [] like we've all become used to in query strings. The spec that encode_www_form uses is in accordance with the HTML5 definition of application/x-www-form-urlencoded data.

You can define a context for your application say ExampleContext which will hold the context of your application and then use it to instantiate an activity like this:

var intent = new Intent(Application.ApplicationContext, typeof(Activity2));
intent.AddFlags(ActivityFlags.NewTask);
Application.ApplicationContext.StartActivity(intent);

Please bear in mind that this code is written in C# as I use MonoDroid, but I believe it is very similar to Java. For how to create an ApplicationContext look at this thread

This is how I made my Application Class

    [Application]
    public class Application : Android.App.Application, IApplication
    {
        public Application(IntPtr handle, JniHandleOwnership transfer) : base(handle, transfer)
        {

        }
        public object MyObject { get; set; }
    }

As mentioned in other answers, the Panel generates a <div> in HTML, while the PlaceHolder does not. But there are a lot more reasons why you could choose either one.

Why a PlaceHolder?

Since it generates no tag of it's own you can use it safely inside other element that cannot contain a <div>, for example:

<table>
    <tr>
        <td>Row 1</td>
    </tr>
    <asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
</table>

You can also use a PlaceHolder to control the Visibility of a group of Controls without wrapping it in a <div>

<asp:PlaceHolder ID="PlaceHolder1" runat="server" Visible="false">
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    <br />
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</asp:PlaceHolder>

Why a Panel

It generates it's own <div> and can also be used to wrap a group of Contols. But a Panel has a lot more properties that can be useful to format it's content:

<asp:Panel ID="Panel1" runat="server" Font-Bold="true"
    BackColor="Green" ForeColor="Red" Width="200"
    Height="200" BorderColor="Black" BorderStyle="Dotted">
    Red text on a green background with a black dotted border.
</asp:Panel>

But the most useful feature is the DefaultButton property. When the ID matches a Button in the Panel it will trigger a Form Post with Validation when enter is pressed inside a TextBox. Now a user can submit the Form without pressing the Button.

<asp:Panel ID="Panel1" runat="server" DefaultButton="Button1">
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <br />
    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
        ErrorMessage="Input is required" ValidationGroup="myValGroup"
        Display="Dynamic" ControlToValidate="TextBox1"></asp:RequiredFieldValidator>
    <br />
    <asp:Button ID="Button1" runat="server" Text="Button" ValidationGroup="myValGroup" />
</asp:Panel>

Try the above snippet by pressing enter inside TextBox1

Use:

$a = 'How are you?';
if (mb_strpos($a, 'are')) {
    echo 'true';
}

It performs a multi-byte safe strpos() operation.

I would use the Dictionary<TKey, TValue> (so long as each key is unique).

EDIT: Sorry, realised you wanted to add it to a specific position. My bad. You could use a SortedDictionary but this still won't let you insert.

Please Note: The original poster was not specifically asking about PHP. All the php centric answers make large assumptions not relevant to the actual question.

The default error log as opposed to the scripts error logs usually has the (more) specific error. often it will be permissions denied or even an interpreter that can't be found.

This means the fault almost always lies with your script. e.g you uploaded a perl script but didnt give it execute permissions? or perhaps it was corrupted in a linux environment if you write the script in windows and then upload it to the server without the line endings being converted you will get this error.

in perl if you forget

print "content-type: text/html\r\n\r\n";

you will get this error

There are many reasons for it. so please first check your error log and then provide some more information.

The default error log is often in /var/log/httpd/error_log or /var/log/apache2/error.log.

The reason you look at the default error logs (as indicated above) is because errors don't always get posted into the custom error log as defined in the virtual host.

Assumes linux and not necessarily perl

Use array_values.

$myarray = array_values($myarray);

I know this is bad.. But I have been in hard situation where it is impossible to put this back to controller or model.

My solution is to call a function on model. It can be do inside a view. But you have to make sure the model has been loaded to your controller first.

Say your model main_model, you can call function on the model like this on your view : $this->main_model->your_function();

Hope this help. :)

I think you can do this with the hyperref package, although I've not tried it myself. From the relevant LaTeX Wikibook section:

The hyperref package introduces another useful command; \autoref{}. This command creates a reference with additional text corresponding to the targets type, all of which will be a hyperlink. For example, the command \autoref{sec:intro} would create a hyperlink to the \label{sec:intro} command, wherever it is. Assuming that this label is pointing to a section, the hyperlink would contain the text "section 3.4", or similar (capitalization rules will be followed, which makes this very convenient). You can customize the prefixed text by redefining \typeautorefname to the prefix you want, as in:

\def\subsectionautorefname{section}

Here is another solution which uses any/2

map(select(any(.Names[]; contains("data"))|not)|.Id)[]

with the sample data and the -r option it produces

cb94e7a42732b598ad18a8f27454a886c1aa8bbba6167646d8f064cd86191e2b
a4b7e6f5752d8dcb906a5901f7ab82e403b9dff4eaaeebea767a04bac4aada19

PHP7, in php.ini file, remove the ";" before extension=openssl

Those two keywords are directly attached with Inheritance it is a core concept of OOP. When we inherit some class to another class we can use extends but when we are going to inherit some interfaces to our class we can't use extends we should use implements and we can use extends keyword to inherit interface from another interface.

You can use JSON.stringify(object) with an object and I just wrote a function that'll recursively convert an array to an object, like this JSON.stringify(convArrToObj(array)), which is the following code (more detail can be found on this answer):

// Convert array to object
var convArrToObj = function(array){
    var thisEleObj = new Object();
    if(typeof array == "object"){
        for(var i in array){
            var thisEle = convArrToObj(array[i]);
            thisEleObj[i] = thisEle;
        }
    }else {
        thisEleObj = array;
    }
    return thisEleObj;
}

To make it more generic, you can override the JSON.stringify function and you won't have to worry about it again, to do this, just paste this at the top of your page:

// Modify JSON.stringify to allow recursive and single-level arrays
(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        return oldJSONStringify(convArrToObj(input));
    };
})();

And now JSON.stringify will accept arrays or objects! (link to jsFiddle with example)

Edit:

Here's another version that's a tad bit more efficient, although it may or may not be less reliable (not sure -- it depends on if JSON.stringify(array) always returns [], which I don't see much reason why it wouldn't, so this function should be better as it does a little less work when you use JSON.stringify with an object):

(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        if(oldJSONStringify(input) == '[]')
            return oldJSONStringify(convArrToObj(input));
        else
            return oldJSONStringify(input);
    };
})();

You can use a native Filter Validator

filter_var($url, FILTER_VALIDATE_URL);

Validates value as URL (according to » http://www.faqs.org/rfcs/rfc2396), optionally with required components. Beware a valid URL may not specify the HTTP protocol http:// so further validation may be required to determine the URL uses an expected protocol, e.g. ssh:// or mailto:. Note that the function will only find ASCII URLs to be valid; internationalized domain names (containing non-ASCII characters) will fail.

Example:

if (filter_var($url, FILTER_VALIDATE_URL) === FALSE) {
    die('Not a valid URL');
}

I came across this discussion only now, so I hope my comment is still useful. I am involved with MathJax and, from how I understand your situation, I think that it would be a good way to solve the problem: you leave your LaTeX code as is, and let MathJax render the mathematics upon viewing.

Is there any reason why you would prefer images?

please try to install the dependencie with pip, run this command:

sudo pip install -U setuptools

This is a bit outside the scope of your question, but to avoid any potential confusion for readers who are new to VBA: End and End Sub are not the same. They don't perform the same task.

End puts a stop to ALL code execution and you should almost always use Exit Sub (or Exit Function, respectively).

End halts ALL exectution. While this sounds tempting to do it also clears all global and static variables. (source)

See also the MSDN dox for the End Statement

When executed, the End statement resets allmodule-level variables and all static local variables in allmodules. To preserve the value of these variables, use the Stop statement instead. You can then resume execution while preserving the value of those variables.

Note The End statement stops code execution abruptly, without invoking the Unload, QueryUnload, or Terminate event, or any other Visual Basic code. Code you have placed in the Unload, QueryUnload, and Terminate events offorms andclass modules is not executed. Objects created from class modules are destroyed, files opened using the Open statement are closed, and memory used by your program is freed. Object references held by other programs are invalidated.

Nor is End Sub and Exit Sub the same. End Sub can't be called in the same way Exit Sub can be, because the compiler doesn't allow it.

This again means you have to Exit Sub, which is a perfectly legal operation:

Exit Sub
Immediately exits the Sub procedure in which it appears. Execution continues with the statement following the statement that called the Sub procedure. Exit Sub can be used only inside a Sub procedure.

Additionally, and once you get the feel for how procedures work, obviously, End Sub does not clear any global variables. But it does clear local (Dim'd) variables:

End Sub
Terminates the definition of this procedure.

Try $('#score_here').html=total;

I resolved this problem by navigating to C:\Python27\Scripts folder and then run file.py file instead of C:\Python27 folder

1 byte may hold 1 character. For Example: Refer Ascii values for each character & convert into binary. This is how it works.

value 255 is stored as (11111111) base 2. Visit this link for knowing more about binary conversion. http://acc6.its.brooklyn.cuny.edu/~gurwitz/core5/nav2tool.html

If you really want _.pluck support back, you can use a mixin:

const _ = require("lodash")

_.mixin({
    pluck: _.map
})

Because map now supports a string (the "iterator") as an argument instead of a function.

(Search for generate204)

Relevant section:

Among the different objects, a javascript function triggers a generate204 request sent to the video server that is supposed to serve the video. This starts the video prefetch, which has two main goals: first, it forces the client to perform the DNS resolution of the video server name. Second, it forces the client to open a TCP connection toward the video server. Both help to speed-up the video download phase.

In addition, the generate204 request has exactly the same format and options of the real video download request, so that the video server is eventually warned that a client will possibly download that video very soon. Note that the video server replies with a 204 No Content response, as implied by the command, and no video content is downloaded so far.

Official(?) instructions: http://peak.telecommunity.com/DevCenter/EasyInstall#uninstalling-packages

If you have replaced a package with another version, then you can just delete the package(s) you don't need by deleting the PackageName-versioninfo.egg file or directory (found in the installation directory).

If you want to delete the currently installed version of a package (or all versions of a package), you should first run:

easy_install -mxN PackageName

This will ensure that Python doesn't continue to search for a package you're planning to remove. After you've done this, you can safely delete the .egg files or directories, along with any scripts you wish to remove.

Clearing a list in place will affect all other references of the same list.

For example, this method doesn't affect other references:

>>> a = [1, 2, 3]
>>> b = a
>>> a = []
>>> print(a)
[]
>>> print(b)
[1, 2, 3]

But this one does:

>>> a = [1, 2, 3]
>>> b = a
>>> del a[:]      # equivalent to   del a[0:len(a)]
>>> print(a)
[]
>>> print(b)
[]
>>> a is b
True

You could also do:

>>> a[:] = []

When you use recv in connection with select if the socket is ready to be read from but there is no data to read that means the client has closed the connection.

Here is some code that handles this, also note the exception that is thrown when recv is called a second time in the while loop. If there is nothing left to read this exception will be thrown it doesn't mean the client has closed the connection :

def listenToSockets(self):

    while True:

        changed_sockets = self.currentSockets

        ready_to_read, ready_to_write, in_error = select.select(changed_sockets, [], [], 0.1)

        for s in ready_to_read:

            if s == self.serverSocket:
                self.acceptNewConnection(s)
            else:
                self.readDataFromSocket(s)

And the function that receives the data :

def readDataFromSocket(self, socket):

    data = ''
    buffer = ''
    try:

        while True:
            data = socket.recv(4096)

            if not data: 
                break

            buffer += data

    except error, (errorCode,message): 
        # error 10035 is no data available, it is non-fatal
        if errorCode != 10035:
            print 'socket.error - ('+str(errorCode)+') ' + message


    if data:
        print 'received '+ buffer
    else:
        print 'disconnected'

It should be like this.

In your Component

computed: {
        ...mapGetters({
                nameFromStore: 'name'
            }),
        name: {
           get(){
             return this.nameFromStore
           },
           set(newName){
             return newName
           } 
        }
    }

In your store

export const store = new Vuex.Store({
         state:{
             name : "Stackoverflow"
         },
         getters: {
                 name: (state) => {
                     return state.name;
                 }
         }
}

Let me know if this helps! JFV

If your template.html file is just HTML and not a React component, then you can't require it in the same way you would do with a JS file.

However, if you are using Browserify — there is a transform called stringify which will allow you to require non-js files as strings. Once you have added the transform, you will be able to require HTML files and they will export as though they were just strings.

Once you have required the HTML file, you'll have to inject the HTML string into your component, using the dangerouslySetInnerHTML prop.

var __html = require('./template.html');
var template = { __html: __html };

React.module.exports = React.createClass({
  render: function() {
    return(
      <div dangerouslySetInnerHTML={template} />
    );
  }
});

This goes against a lot of what React is about though. It would be more natural to create your templates as React components with JSX, rather than as regular HTML files.

The JSX syntax makes it trivially easy to express structured data, like HTML, especially when you use stateless function components.

If your template.html file looked something like this

<div class='foo'>
  <h1>Hello</h1>
  <p>Some paragraph text</p>
  <button>Click</button>
</div>

Then you could convert it instead to a JSX file that looked like this.

module.exports = function(props) {
  return (
    <div className='foo'>
      <h1>Hello</h1>
      <p>Some paragraph text</p>
      <button>Click</button>
    </div>
  );
};

Then you can require and use it without needing stringify.

var Template = require('./template');

module.exports = React.createClass({
  render: function() {
    var bar = 'baz';
    return(
      <Template foo={bar}/>
    );
  }
});

It maintains all of the structure of the original file, but leverages the flexibility of React's props model and allows for compile time syntax checking, unlike a regular HTML file.

This is a good example where you want to get count of Pincode which stored in the last of address field

SELECT DISTINCT
    RIGHT (address, 6),
    count(*) AS count
FROM
    datafile
WHERE
    address IS NOT NULL
GROUP BY
    RIGHT (address, 6)

Public Sub UpdateMyFunctions()
    Dim myRange As Range
    Dim rng As Range

    'Considering The Functions are in Range A1:B10
    Set myRange = ActiveSheet.Range("A1:B10")

    For Each rng In myRange
        rng.Formula = rng.Formula
    Next
End Sub

Each image has a resource-number, which is an integer. Pass this number to "setImageResource" and you should be ok.

Check this link for further information:

e.g.:

imageView.setImageResource(R.drawable.myimage);

Maybe someone encounters a similar warning I had with a Scala project.

Package names doesn't correspond to directories structure, this may cause problems with resolve to classes from this file Inspection for files with package statement which does not correspond to package structure.

The file was in the right location, so the helper solutions the IDE provides are not helpful The Move File says file already exists (which is true) and Rename Package would actually move it to the incorrect package.

The problem is that if you have Scala Objects, you have to make sure that the first object in the file has the same name as the filename, so the solution is to move the objects inside the file.

Since your desired output is sorted, you also need to sort it:

>>> j=[4, 5, 6, 7, 1, 3, 7, 5]
>>> sorted(x for x in j if x >= 5)
[5, 5, 6, 7, 7]

You can do this simply like this

$('#image_id').click(function() {
  $("#some_id iframe").attr('src', $("#some_id iframe", parent).attr('src') + '?autoplay=1'); 
});

where image_id is your image id you are clicking and some_id is id of div in which iframe is also you can use iframe id directly.

For a Fragment you can simply add

  getActivity().onBackPressed();

to your code

It is correct, but perhaps not useful.

As there is nothing to wait on – no calls to blocking APIs which could operate asynchronously – then you are setting up structures to track asynchronous operation (which has overhead) but then not making use of that capability.

For example, if the service layer was performing DB operations with Entity Framework which supports asynchronous calls:

public Task<BackOfficeResponse<List<Country>>> ReturnAllCountries()
{
    using (db = myDBContext.Get()) {
      var list = await db.Countries.Where(condition).ToListAsync();

       return list;
    }
}

You would allow the worker thread to do something else while the db was queried (and thus able to process another request).

Await tends to be something that needs to go all the way down: it is very hard to retro-fit into an existing system.

Add below lines in your .profile path

PATH=$PATH:$HOME/bin:$Dir_where_script_exists

export PATH

Now your script should work without ./

Console.Read() takes a character and returns the ascii value of that character.So if you want to take the symbol that was entered by the user instead of its ascii value (ex:if input is 5 then symbol = 5, ascii value is 53), you have to parse it using int.parse() but it raises a compilation error because the return value of Console.Read() is already int type. So you can get the work done by using Console.ReadLine() instead of Console.Read() as follows.

int userInput = int.parse(Console.ReadLine());

here, the output of the Console.ReadLine() would be a string containing a number such as "53".By passing it to the int.Parse() we can convert it to int type.

Tools -> options -> git and selecting 'use system git' did the magic for me.

You can use the for..in TypeScript operator to access the index when dealing with collections.

var test = [7,8,9];
for (var i in test) {
   console.log(i + ': ' + test[i]);
} 

Output:

 0: 7
 1: 8
 2: 9

You need to install C compiler, C/C++ extension, configure launch.json and tasks.json to be able to debug C code.

This article would guide you how to do it: https://medium.com/@jerrygoyal/run-debug-intellisense-c-c-in-vscode-within-5-minutes-3ed956e059d6

We can use Angular event bindings to respond to any DOM event. The syntax is simple. We surround the DOM event name in parentheses and assign a quoted template statement to it. -- reference

Since change is on the list of standard DOM events, we can use it:

(change)="saverange()"

In your particular case, since you're using NgModel, you could break up the two-way binding like this instead:

[ngModel]="range" (ngModelChange)="saverange($event)"

Then

saverange(newValue) {
  this.range = newValue;
  this.Platform.ready().then(() => {
     this.rootRef.child("users").child(this.UserID).child('range').set(this.range)
  })
} 

However, with this approach saverange() is called with every keystroke, so you're probably better off using (change).

The only way to reliably detect if a socket is still connected is to periodically try to send data. Its usually more convenient to define an application level 'ping' packet that the clients ignore, but if the protocol is already specced out without such a capability you should be able to configure tcp sockets to do this by setting the SO_KEEPALIVE socket option. I've linked to the winsock documentation, but the same functionality should be available on all BSD-like socket stacks.

In my case I often get this issue when I first complise a app in debug mode and later try to install the google signed app.

That is because both apps have the same package name but diffent signatures. Since I upgraded to Android lollypop I sometimes even get this error if I uninstall the app via the settings\Apps. If you have this problem check if the app is installed in a other User profile and uninstall it in all user accounts.

You can try the following code:

$("input[name=cols][value=" + value + "]").attr('checked', 'checked');

This will set the attribute checked for the radio columns and value as specified.

This is almost identical to how Karl Shifflet demonstrated a RelayCommand, where Execute fires a predetermined Action<T>. A top-notch solution, if you ask me.

public class RelayCommand : ICommand
{
    private readonly Predicate<object> _canExecute;
    private readonly Action<object> _execute;

    public RelayCommand(Predicate<object> canExecute, Action<object> execute)
    {
        _canExecute = canExecute;
        _execute = execute;
    }

    public event EventHandler CanExecuteChanged
    {
        add => CommandManager.RequerySuggested += value;
        remove => CommandManager.RequerySuggested -= value;
    }

    public bool CanExecute(object parameter)
    {
        return _canExecute(parameter);
    }

    public void Execute(object parameter)
    {
        _execute(parameter);
    }
}

This could then be used as...

public class MyViewModel
{
    private ICommand _doSomething;
    public ICommand DoSomethingCommand
    {
        get
        {
            if (_doSomething == null)
            {
                _doSomething = new RelayCommand(
                    p => this.CanDoSomething,
                    p => this.DoSomeImportantMethod());
            }
            return _doSomething;
        }
    }
}

I found This simpler yet powerful tutorial which uses the fileReader Object. It simply creates an img element and, using the fileReader object, assigns its source attribute as the value of the form input

function previewFile() {_x000D_
  var preview = document.querySelector('img');_x000D_
  var file    = document.querySelector('input[type=file]').files[0];_x000D_
  var reader  = new FileReader();_x000D_
_x000D_
  reader.onloadend = function () {_x000D_
    preview.src = reader.result;_x000D_
  }_x000D_
_x000D_
  if (file) {_x000D_
    reader.readAsDataURL(file);_x000D_
  } else {_x000D_
    preview.src = "";_x000D_
  }_x000D_
}

<input type="file" onchange="previewFile()"><br>_x000D_

If the first segment doesn't start with / it is a relative route. router.navigate needs a relativeTo parameter for relative navigation

Either you make the route absolute:

this.router.navigate(['/foo-content', 'bar-contents', 'baz-content', 'page'], this.params.queryParams)

or you pass relativeTo

this.router.navigate(['../foo-content', 'bar-contents', 'baz-content', 'page'], {queryParams: this.params.queryParams, relativeTo: this.currentActivatedRoute})

From what I understand they are independent of one another. By keeping the session timeout less than or equal to the authentication timeout, you can make sure any user-specific session variables are not persisted after the authentication has timed out (if that is your concern, which I think is the normal one when asking this question). Of course, you'll have to manually handle the disposal of session variables upon log-out.

Here is a decent response that may answer your question or at least point you in the right direction:

The scp operation is separate from your ssh login. You will need to issue an ssh command similar to the following one assuming jdoe is account with which you log into the remote system and that the remote system is example.com:

scp [email protected]:/somedir/table /home/me/Desktop/.

The scp command issued from the system where /home/me/Desktop resides is followed by the userid for the account on the remote server. You then add a ":" followed by the directory path and file name on the remote server, e.g., /somedir/table. Then add a space and the location to which you want to copy the file. If you want the file to have the same name on the client system, you can indicate that with a period, i.e. "." at the end of the directory path; if you want a different name you could use /home/me/Desktop/newname, instead. If you were using a nonstandard port for SSH connections, you would need to specify that port with a "-P n" (capital P), where "n" is the port number. The standard port is 22 and if you aren't specifying it for the SSH connection then you won't need that.

Nick Vogt at H3XED posted this syntax: https://www.youtube.com/v/VIDEOID?version=3&vq=hd1080

Take this link and replace the expression "VIDEOID" with the (shortened/shared) ID of the video.

Exapmple for ID: i3jNECZ3ybk looks like this: ... /v/i3jNECZ3ybk?version=3&vq=hd1080

What you get as a result is the standalone 1080p video but not in the Tube environment.

Do a quick 'record macro' to see the color number associated with the color you're looking for (yellow highlight is 65535). Then erase the code and put

Sub Name()
Selection.Interior.Color = 65535 '(your number may be different depending on the above)
End Sub

I know this might be an old question but I just found myself in a situation where I had to implement this feature in a Laravel 5.7 app. Below is what worked from me.

 $articles = Articles::where("created_at",">", Carbon::now()->subMonths(3))->get();

You will also need to use Carbon

use Carbon\Carbon;

Try this one:

#!/bin/bash
psql -U postgres -d database_name -c "SELECT c_defaults  FROM user_info WHERE c_uid = 'testuser'"

Or using su:

#!/bin/bash
su -c "psql -d database_name -c \"SELECT c_defaults  FROM user_info WHERE c_uid = 'testuser'\"" postgres

And also sudo:

#!/bin/bash
sudo -u postgres -H -- psql -d database_name -c "SELECT c_defaults  FROM user_info WHERE c_uid = 'testuser'"

Using get and set methods within a service you can passing messages between controllers very easily.

var myApp = angular.module("myApp",[]);

myApp.factory('myFactoryService',function(){


    var data="";

    return{
        setData:function(str){
            data = str;
        },

        getData:function(){
            return data;
        }
    }


})


myApp.controller('FirstController',function($scope,myFactoryService){
    myFactoryService.setData("Im am set in first controller");
});



myApp.controller('SecondController',function($scope,myFactoryService){
    $scope.rslt = myFactoryService.getData();
});

in HTML HTML you can check like this

<div ng-controller='FirstController'>  
</div>

<div ng-controller='SecondController'>
    {{rslt}}
</div>

You can also cross reference repos:

githubuser/repository#xxx

xxx being the issue number

This is my xml customTextView Object here you can use simply TextView to replace on Tag.

 <com.wedoapps.crickethisabkitab.utils.view.montserrat.CustomTextView

                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="@dimen/_10sdp"
                android:layout_marginBottom="@dimen/_10sdp"
                android:layout_marginStart="@dimen/_5sdp"
                android:layout_marginEnd="@dimen/_5sdp"
                android:text="@string/please_rate_us_5_star_on_play_store"
                android:textAllCaps="false"
                android:textColor="@color/green"
                android:textSize="@dimen/_25ssp"
                android:textStyle="bold"
                android:visibility="visible"
                android:linksClickable="true"
                android:autoLink="web|phone"/>

And here is My Java File code. i have set my html text on server just replace your text on textview object. i have put this code is marquee tag with clickable if any links on this textview to open mobile or webBrowser.

CustomTextView lblRateUsPlayStore = findViewById(R.id.lblRateUsPlayStore);
lblRateUsPlayStore.setMovementMethod(LinkMovementMethod.getInstance());
                        lblRateUsPlayStore.setText( Html.fromHtml(documentSnapshot.getString("DisplayText")));
                        TextViewCompat.setAutoSizeTextTypeUniformWithConfiguration(lblRateUsPlayStore, 12, 20, 2, 1);

                        lblRateUsPlayStore.setEllipsize(TextUtils.TruncateAt.MARQUEE);

                        // Set marquee repeat limit (unlimited)
                        lblRateUsPlayStore.setMarqueeRepeatLimit(-1);
                        lblRateUsPlayStore.setHorizontallyScrolling(true);
                        lblRateUsPlayStore.setSelected(true);
                        lblRateUsPlayStore.setLinksClickable(true);
                        lblRateUsPlayStore.setFocusableInTouchMode(true);
                        lblRateUsPlayStore.setFocusable(true);

You can use various local storage mechanisms to store this data in the browser such as Web Storage, IndexedDB, WebSQL (deprecated) and File API (deprecated and only available in Chrome) (and UserData with IE).

The simplest and most widely supported is WebStorage where you have persistent storage (localStorage) or session based (sessionStorage) which is in memory until you close the browser. Both share the same API.

You can for example (simplified) do something like this when the page is about to reload:

window.onbeforeunload = function() {
    localStorage.setItem("name", $('#inputName').val());
    localStorage.setItem("email", $('#inputEmail').val());
    localStorage.setItem("phone", $('#inputPhone').val());
    localStorage.setItem("subject", $('#inputSubject').val());
    localStorage.setItem("detail", $('#inputDetail').val());
    // ...
}

Web Storage works synchronously so this may work here. Optionally you can store the data for each blur event on the elements where the data is entered.

At page load you can check:

window.onload = function() {

    var name = localStorage.getItem("name");
    if (name !== null) $('#inputName').val("name");

    // ...
}

getItem returns null if the data does not exist.

Use sessionStorage instead of localStorage if you want to store only temporary.

Update: From now on, I use .collapse and $('.collapse').show().

For Bootstrap 4 Alpha 6

For Bootstrap 4 you have to use .hidden-xs-up.

https://v4-alpha.getbootstrap.com/layout/responsive-utilities/#available-classes

The .hidden-*-up classes hide the element when the viewport is at the given breakpoint or wider. For example, .hidden-md-up hides an element on medium, large, and extra-large viewports.

There is also hidden HTML5 attribute.

https://v4-alpha.getbootstrap.com/content/reboot/#html5-hidden-attribute

HTML5 adds a new global attribute named [hidden], which is styled as display: none by default. Borrowing an idea from PureCSS, we improve upon this default by making [hidden] { display: none !important; } to help prevent its display from getting accidentally overridden. While [hidden] isn’t natively supported by IE10, the explicit declaration in our CSS gets around that problem.

<input type="text" hidden>

There is also .invisible which does affect the layout.

https://v4-alpha.getbootstrap.com/utilities/invisible-content/

The .invisible class can be used to toggle only the visibility of an element, meaning its display is not modified and the element can still affect the flow of the document.

Documentation on d.android.com: http://developer.android.com/distribute/googleplay/promote/linking.html

you do not need a seperate batch file to exit a loop using exit /b if you are using call instead of goto like

call :loop

echo loop finished

goto :eof

:loop
FOR /L %%I IN (1,1,10) DO (
    echo %%I
    IF %%I==5 exit /b
)

in this case, the "exit /b" will exit the 'call' and continue from the line after 'call' So the output is this:

1
2
3
4
5
loop finished

The building blocks of REST are mainly the resources (and URI) and the hypermedia. In this context, GET is the way to get a representation of the resource (which can indeed be mapped to a SELECT in CRUD terms).

However, you shouldn't necessarily expect a one-to-one mapping between CRUD operations and HTTP verbs. The main difference between PUT and POST is about their idempotent property. POST is also more commonly used for partial updates, as PUT generally implies sending a full new representation of the resource.

I'd suggest reading this:

• http://roy.gbiv.com/untangled/2009/it-is-okay-to-use-post
• http://roy.gbiv.com/untangled/2008/rest-apis-must-be-hypertext-driven

The HTTP specification is also a useful reference:

The PUT method requests that the enclosed entity be stored under the supplied Request-URI.

[...]

The fundamental difference between the POST and PUT requests is reflected in the different meaning of the Request-URI. The URI in a POST request identifies the resource that will handle the enclosed entity. That resource might be a data-accepting process, a gateway to some other protocol, or a separate entity that accepts annotations. In contrast, the URI in a PUT request identifies the entity enclosed with the request -- the user agent knows what URI is intended and the server MUST NOT attempt to apply the request to some other resource. If the server desires that the request be applied to a different URI,

I drop a lot of same-sized same-dp screens, ignore height/width swap and include some sorting results.

To perform *new tile_tree_apple the constructor of tile_tree_apple should be called, but in this place compiler knows nothing about tile_tree_apple, so it can't use the constructor.

If you put

tile tile_tree::tick() {if (rand()%20==0) return *new tile_tree_apple;};

in separate cpp file which has the definition of class tile_tree_apple or includes the header file which has the definition everything will work fine.

You can get the property the same way as you set it.

foo = {
 bar: "value"
}

You set the value foo["bar"] = "baz";

To get the value foo["bar"]

will return "baz".

On CYGwin, you can install this as a typical package in the first screen. Look for

libssl-devel

Combination of keyup and change is not necessarily enough (browser's autocomplete and paste using mouse also changes the contents of a text box, but doesn't fire either of these events):

jquery change not working incase of dynamic value change

Use /config.php.

JS:

<div onclick="location.href='url'">content</div>

jQuery:

$("div").click(function(){
   window.location=$(this).find("a").attr("href"); return false;
});

Make sure to use cursor:pointer for these DIVs

From the documentation:

You cannot use ORDER BY or LIMIT in a multiple-table DELETE.

The FindBugs initial approach involves XML configuration files aka filters. This is really less convenient than the PMD solution but FindBugs works on bytecode, not on the source code, so comments are obviously not an option. Example:

<Match>
   <Class name="com.mycompany.Foo" />
   <Method name="bar" />
   <Bug pattern="DLS_DEAD_STORE_OF_CLASS_LITERAL" />
</Match>

However, to solve this issue, FindBugs later introduced another solution based on annotations (see SuppressFBWarnings) that you can use at the class or at the method level (more convenient than XML in my opinion). Example (maybe not the best one but, well, it's just an example):

@edu.umd.cs.findbugs.annotations.SuppressFBWarnings(
    value="HE_EQUALS_USE_HASHCODE", 
    justification="I know what I'm doing")

Note that since FindBugs 3.0.0 SuppressWarnings has been deprecated in favor of @SuppressFBWarnings because of the name clash with Java's SuppressWarnings.

A simple way to see the Git commit short version and the Git commit message is:

git log --oneline

Note that this is shorthand for

git log --pretty=oneline --abbrev-commit

Try this

function setAttribs(elm, ob) {
    //var r = [];
    //var i = 0;
    for (var z in ob) {
        if (ob.hasOwnProperty(z)) {
            try {
                elm[z] = ob[z];
            }
            catch (er) {
                elm.setAttribute(z, ob[z]);
            }
        }
    }
    return elm;
}

DEMO: HERE

I wanted to match a string that ends with ".*" For this I had to use the following:

"^.*\\.\\*$"

Kinda silly if you think about it :D Heres what it means. At the start of the string there can be any character zero or more times followed by a dot "." followed by a star (*) at the end of the string.

I hope this comes in handy for someone. Thanks for the backslash thing to Fabian.

From W3 web site Common HTML entities used for typography

For the sake of portability, Unicode entity references should be reserved for use in documents certain to be written in the UTF-8 or UTF-16 character sets. In all other cases, the alphanumeric references should be used.

Translation: If you are looking for widest support, go with —

1. Hard to copy and paste.

   Not true. Enable QuickEdit, either in the properties of the shortcut, or in the properties of the CMD window (right-click on the title bar), and you can mark text directly. Right-click copies marked text into the clipboard. When no text is marked, a right-click pastes text from the clipboard.

   

2. Hard to resize the window.

   True. Console2 (see below) does not have this limitation.

3. Hard to open another window (no menu options do this).

   Not true. Use start cmd or define an alias if that's too much hassle:

   doskey nw=start cmd /k $*
   

4. Seems to always start in C:\Windows\System32, which is super useless.

   Not true. Or rather, not true if you define a start directory in the properties of the shortcut

   

   or by modifying the AutoRun registry value. Shift-right-click on a folder allows you to launch a command prompt in that folder.

5. Weird scrolling. Sometimes it scrolls down really far into blank space, and you have to scroll up to where the window is actually populated

   Never happened to me.

An alternative to plain CMD is Console2, which uses CMD under the hood, but provides a lot more configuration options.

$(document).ready(function() {
    $(document).on("click", ".question", function(e) {
       var checked = $(this).find("input:checkbox").is(":checked");
       if (checked) {
           $('.answer').show(300);
       } else {
           $('.answer').hide(300);
       }
    });
});

You want reorder(). Here is an example with dummy data

set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))

require("ggplot2")

p1 <- ggplot(df, aes(x = Category, y = Count)) +
         geom_bar(stat = "identity")

p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
         geom_bar(stat = "identity")

require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))

Giving:

Use reorder(Category, Count) to have Category ordered from low-high.

$('form').submit( function(e){

     e.preventDefault();

     //later you decide you want to submit
     $(this).trigger('submit');     or     $(this).trigger('anyEvent');

You can use like that:

data is DataTable

data.DefaultView.ToTable(true, "Id", "Name", "Role", "DC1", "DC2", "DC3", "DC4", "DC5", "DC6", "DC7");  

but performance will be down. try to use below code:

data.AsEnumerable().Distinct(System.Data.DataRowComparer.Default).ToList();  

For Performance ; http://onerkaya.blogspot.com/2013/01/distinct-dataviewtotable-vs-linq.html

Try this:

//KITKAT
i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, CHOOSE_IMAGE_REQUEST);

Use the following in the onActivityResult:

Uri selectedImageURI = data.getData();
input = c.getContentResolver().openInputStream(selectedImageURI);
BitmapFactory.decodeStream(input , null, opts);

You can regroup your steps functions calls in a facade function :

sub facade()
    call step1()
    call step2()
    call step3()
    call step4()
    call step5()
end sub

Then, let your error handling be in an upper function that calls the facade :

sub main()
    On error resume next

    call facade()

    If Err.Number <> 0 Then
        ' MsgBox or whatever. You may want to display or log your error there
        msgbox Err.Description
        Err.Clear
    End If

    On Error Goto 0
end sub

Now, let's suppose step3() raises an error. Since facade() doesn't handle errors (there is no On error resume next in facade()), the error will be returned to main() and step4() and step5() won't be executed.

Your error handling is now refactored in 1 code block

If the column is a timestamp you can do the following:

        if(fromDate!=null){
            criteria.add(Restrictions.sqlRestriction("TRUNC(COLUMN) >= TO_DATE('" + dataFrom + "','dd/mm/yyyy')"));
        }
        if(toDate!=null){               
            criteria.add(Restrictions.sqlRestriction("TRUNC(COLUMN) <= TO_DATE('" + dataTo + "','dd/mm/yyyy')"));
        }

        resultDB = criteria.list();

You want to use regexp_substr() for this. This should work for your example:

select regexp_substr(val, '[^/]+/[^/]+', 1, 1) as part1,
       regexp_substr(val, '[^/]+$', 1, 1) as part2
from (select 'F/P/O' as val from dual) t

Here, by the way, is the SQL Fiddle.

Oops. I missed the part of the question where it says the last delimiter. For that, we can use regex_replace() for the first part:

select regexp_replace(val, '/[^/]+$', '', 1, 1) as part1,
       regexp_substr(val, '[^/]+$', 1, 1) as part2
from (select 'F/P/O' as val from dual) t

And here is this corresponding SQL Fiddle.

I almost always use the standard formating ShortDateString, because I want the user to be in control of the actual output of the date.

Code

   Dim d As DateTime = Now
   Debug.WriteLine(d.ToLongDateString)
   Debug.WriteLine(d.ToShortDateString)
   Debug.WriteLine(d.ToString("d"))
   Debug.WriteLine(d.ToString("yyyy-MM-dd"))

Note that these results will vary depending on the culture settings on your computer.

You are doing integer arithmetic, so there the result is correct. Try

percentage=((double)number/total)*100;

BTW the %f expects a double not a float. By pure luck that is converted here, so it works out well. But generally you'd mostly use double as floating point type in C nowadays.

Not sure if this would have a faster computational time, but another option...

$acceptedFormats = array('gif', 'png', 'jpg');

if(!in_array(pathinfo($filename, PATHINFO_EXTENSION), $acceptedFormats))) {
    echo 'error';
}

This might be because of the transitive dependencies.

Try to add/ remove the scope from the JSTL library.

This worked for me!

In android-N, this feature is included in it. check Number-blocking update for android N

Android N now supports number-blocking in the platform and provides a framework API to let service providers maintain a blocked-number list. The default SMS app, the default phone app, and provider apps can read from and write to the blocked-number list. The list is not accessible to other app.

advantage of are:

1. Numbers blocked on calls are also blocked on texts
2. Blocked numbers can persist across resets and devices through the Backup & Restore feature
3. Multiple apps can use the same blocked numbers list

For more information, see android.provider.BlockedNumberContract

Update an existing project.

To compile your app against the Android N platform, you need to use the Java 8 Developer Kit (JDK 8), and in order to use some tools with Android Studio 2.1, you need to install the Java 8 Runtime Environment (JRE 8).

Open the build.gradle file for your module and update the values as follows:

android {
  compileSdkVersion 'android-N'
  buildToolsVersion 24.0.0 rc1
  ...

  defaultConfig {
     minSdkVersion 'N'
     targetSdkVersion 'N'
     ...
  }
  ...
}

I got this problem during debug mode and the missing file was from a static library I was using. The problem was solved by using step over instead of step into during debugging

Simply said and without revealing the kitchen secrets: a set in general, is a collection that contains no duplicate elements, and whose elements are in no particular order. So, A HashSet<T> is similar to a generic List<T>, but is optimized for fast lookups (via hashtables, as the name implies) at the cost of losing order.

Answering this just in case if someone else like me stumbles upon this post among many that advise use of JavaScripts for changing iframe height to 100%.

I strongly recommend that you see and try this option specified at How do you give iframe 100% height before resorting to a JavaScript based option. The referenced solution works perfectly for me in all of the testing I have done so far. Hope this helps someone.

You can use Python 3.6's f-strings for variables inside multi-line or lengthy single-line strings. You can manually specify newline characters using \n.

Variables in a multi-line string

string1 = "go"
string2 = "now"
string3 = "great"

multiline_string = (f"I will {string1} there\n"
                    f"I will go {string2}.\n"
                    f"{string3}.")

print(multiline_string)

I will go there
I will go now
great

Variables in a lengthy single-line string

string1 = "go"
string2 = "now"
string3 = "great"

singleline_string = (f"I will {string1} there. "
                     f"I will go {string2}. "
                     f"{string3}.")

print(singleline_string)

I will go there. I will go now. great.

Alternatively, you can also create a multiline f-string with triple quotes.

multiline_string = f"""I will {string1} there.
I will go {string2}.
{string3}."""

I figured out that in my case, my database was in different subnet than the subnet from where i was trying to access the db.
