Websocket and WebRTC can be used together, Websocket as a signal channel of WebRTC, and webrtc is a video/audio/text channel, also WebRTC can be in UDP also in TURN relay, TURN relay support TCP HTTP also HTTPS. Many projects use Websocket and WebRTC together.

Just had to delete all inputs within a div & using the colon in front of the input when targeting gets most everything.

$('#divId').find(':input').val('');

Sorry, I didn't notice the PHP tag - however someone else might be interested in a VB solution:

Module Module1

    Sub Main()
        Dim d As Date = Now
        Dim nextFriday As Date = DateAdd(DateInterval.Weekday, DayOfWeek.Friday - d.DayOfWeek(), Now)
        Console.WriteLine("next friday is " & nextFriday)
        Console.ReadLine()
    End Sub

End Module

For me this was the best way:

1. Check for changes and merge conflicts git fetch
2. Create a new branch git branch my-changes and push to remote
3. Change upstream to new created branch git master -u upstream-branch remotes/origin/my-changes
4. Push your commits to the new upstream branch.
5. Switch back to previous upstream git branch master --set-upstream-to remotes/origin/master

It means you have a null reference somewhere in there. Can you debug the app and stop the debugger when it gets here and investigate? Probably img1 is null or ConfigurationManager.AppSettings.Get("Url") is returning null.

You need to "seed" the generator. Check out this short video, it will clear things up.

Method Object JComboBox.getSelectedItem() returns a value that is wrapped by Object type so you have to cast it accordingly.

Syntax:

YourType varName = (YourType)comboBox.getSelectedItem();`
String value = comboBox.getSelectedItem().toString();

The omp_get_num_threads() function returns the number of threads that are currently in the team executing the parallel region from which it is called. You are calling it outside of the parallel region, which is why it returns 1.

The problem is extra 13 byte which server.py receives at the start. To resolve that write "l = c.recv(1024)" twice before the while loop as below.

print "Receiving..."
l = c.recv(1024) #this receives 13 bytes which is corrupting the data
l = c.recv(1024) # Now actual data starts receiving
while (l):

This resolves the issue, tried with different format and sizes of files. If anyone knows what this starting 13 bytes refers to, please reply.

https://www.lvguowei.me/post/customize-android-seekbar-color/

simple :

<SeekBar
                android:id="@+id/seekBar"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:max="100"
                android:maxHeight="3dp"
                android:minHeight="3dp"
                android:progressDrawable="@drawable/seekbar_style"
                android:thumbTint="@color/positive_color"/>

then a style file:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:id="@android:id/background">
        <shape android:shape="rectangle" >
            <solid
                android:color="@color/positive_color" />
        </shape>
    </item>
    <item android:id="@android:id/progress">
        <clip>
            <shape android:shape="rectangle" >
                <solid
                    android:color="@color/positive_color" />
            </shape>
        </clip>
    </item>
</layer-list>

Basically, there are three main characters which should be always escaped in your HTML and XML files, so they don't interact with the rest of the markups, so as you probably expect, two of them gonna be the syntax wrappers, which are <>, they are listed as below:

 1)  &lt; (<)
    
 2)  &gt; (>)
    
 3)  &amp; (&)

Also we may use double-quote (") as " and the single quote (') as &apos

Avoid putting dynamic content in <script> and <style>.These rules are not for applied for them. For example, if you have to include JSON in a , replace < with \x3c, the U+2028 character with \u2028, and U+2029 with \u2029 after JSON serialisation.)

HTML Escape Characters: Complete List: http://www.theukwebdesigncompany.com/articles/entity-escape-characters.php

So you need to escape <, or & when followed by anything that could begin a character reference. Also The rule on ampersands is the only such rule for quoted attributes, as the matching quotation mark is the only thing that will terminate one. But if you don’t want to terminate the attribute value there, escape the quotation mark.

Changing to UTF-8 means re-saving your file:

Using the character encoding UTF-8 for your page means that you can avoid the need for most escapes and just work with characters. Note, however, that to change the encoding of your document, it is not enough to just change the encoding declaration at the top of the page or on the server. You need to re-save your document in that encoding. For help understanding how to do that with your application read Setting encoding in web authoring applications.

Invisible or ambiguous characters:

A particularly useful role for escapes is to represent characters that are invisible or ambiguous in presentation.

One example would be Unicode character U+200F RIGHT-TO-LEFT MARK. This character can be used to clarify directionality in bidirectional text (eg. when using the Arabic or Hebrew scripts). It has no graphic form, however, so it is difficult to see where these characters are in the text, and if they are lost or forgotten they could create unexpected results during later editing. Using ? (or its numeric character reference equivalent ?) instead makes it very easy to spot these characters.

An example of an ambiguous character is U+00A0 NO-BREAK SPACE. This type of space prevents line breaking, but it looks just like any other space when used as a character. Using   makes it quite clear where such spaces appear in the text.

You can pass thru outside the dynamic statement using User-Defined Variables

1. Create the .env file on your root folder

some sources prefere to use .env.development and .env.production but that's not obligatory.

2. The name of your VARIABLE -must- begin with REACT_APP_YOURVARIABLENAME

it seems that if your environment variable does not start like that so you will have problems

3. Include your variable

to include your environment variable just put on your code process.env.REACT_APP_VARIABLE

You don't have to install any external dependency

I'm pretty certain it is because the DbContext is not at all thread safe. So sharing the thing is never a good idea.

Referencing means taking the address of an existing variable (using &) to set a pointer variable. In order to be valid, a pointer has to be set to the address of a variable of the same type as the pointer, without the asterisk:

int  c1;
int* p1;
c1 = 5;
p1 = &c1;
//p1 references c1

Dereferencing a pointer means using the * operator (asterisk character) to retrieve the value from the memory address that is pointed by the pointer: NOTE: The value stored at the address of the pointer must be a value OF THE SAME TYPE as the type of variable the pointer "points" to, but there is no guarantee this is the case unless the pointer was set correctly. The type of variable the pointer points to is the type less the outermost asterisk.

int n1;
n1 = *p1;

Invalid dereferencing may or may not cause crashes:

• Dereferencing an uninitialized pointer can cause a crash
• Dereferencing with an invalid type cast will have the potential to cause a crash.
• Dereferencing a pointer to a variable that was dynamically allocated and was subsequently de-allocated can cause a crash
• Dereferencing a pointer to a variable that has since gone out of scope can also cause a crash.

Invalid referencing is more likely to cause compiler errors than crashes, but it's not a good idea to rely on the compiler for this.

Reflection is a key mechanism to allow an application or framework to work with code that might not have even been written yet!

Take for example your typical web.xml file. This will contain a list of servlet elements, which contain nested servlet-class elements. The servlet container will process the web.xml file, and create new a new instance of each servlet class through reflection.

Another example would be the Java API for XML Parsing (JAXP). Where an XML parser provider is 'plugged-in' via well-known system properties, which are used to construct new instances through reflection.

And finally, the most comprehensive example is Spring which uses reflection to create its beans, and for its heavy use of proxies

I think the following code clears the difference:

String A = new String("Venugopal");
String B = A;

A = A +"mitul";

System.out.println("A is " + A);
System.out.println("B is " + B);

StringBuffer SA = new StringBuffer("Venugopal");
StringBuffer SB = SA;

SA = SA.append("mitul");

System.out.println("SA is " + SA);
System.out.println("SB is " + SB);

The comm command (short for "common") may be useful comm - compare two sorted files line by line

#find lines only in file1
comm -23 file1 file2 

#find lines only in file2
comm -13 file1 file2 

#find lines common to both files
comm -12 file1 file2 

The man file is actually quite readable for this.

Based in the answer of @G M and paying attention to the @John La Rooy's warning, I was able to append a new row opening the file in 'a'mode.

Even in windows, in order to avoid the newline problem, you must declare it as newline=''.

Now you can open the file in 'a'mode (without the b).

import csv

with open(r'names.csv', 'a', newline='') as csvfile:
    fieldnames = ['This','aNew']
    writer = csv.DictWriter(csvfile, fieldnames=fieldnames)

    writer.writerow({'This':'is', 'aNew':'Row'})

I didn't try with the regular writer (without the Dict), but I think that it'll be ok too.

Alternately, it could also be done as:

<?php
    include("ckeditor/ckeditor.php");
    $CKeditor = new CKeditor();
    $CKeditor->BasePath = 'ckeditor/';
    $CKeditor->editor('editor1');
?>

Note that the last line is having 'editor1' as name, it could be changed as per your requirement.

Use:

import pymysql

Not:

import PyMySQL

That works for me.

`Display

$('#cbxShowHide').click(function(){ this.checked?$('#block').show(1000):$('#block').hide(1000); //time for show });`

open your web.xml file. (if you don't know where is it, then just google it.) it is like this:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
.
.
.
.
</web-app>

just below the <?xml version="1.0" encoding="UTF-8"?> line, add a tag <element> and close it in the very bottom with </element> tag. Done.

You can combine multiple selectors with a comma:

$('#Create .myClass,#Edit .myClass').plugin({options here});

Or if you're going to have a bunch of them, you could add a class to all your form elements and then search within that class. This doesn't get you the supposed speed savings of restricting the search, but I honestly wouldn't worry too much about that if I were you. Browsers do a lot of fancy things to optimize common operations behind your back -- the simple class selector might be faster.

Best way is to handle this in an Ant script. You can create 2 different tasks for the 2 jar files. Specify class A as the main class in the manifst file for the first jar. similarly specify class B as the main class in the manifest file for the second jar.

you can easily run the Ant tasks from Netbeans.

splice will remove array element(s) by index. Use grep, as in your example, to search and remove.

Those solutions mentioned change how your program work.

You can off course put #if DEBUG and #endif around the Console calls, but if you really want to prevent the window from closing only on your dev machine under Visual Studio or if VS isn't running only if you explicitly configure it, and you don't want the annoying 'Press any key to exit...' when running from the command line, the way to go is to use the System.Diagnostics.Debugger API's.

If you only want that to work in DEBUG, simply wrap this code in a [Conditional("DEBUG")] void BreakConditional() method.

// Test some configuration option or another
bool launch;
var env = Environment.GetEnvironmentVariable("LAUNCH_DEBUGGER_IF_NOT_ATTACHED");
if (!bool.TryParse(env, out launch))
    launch = false;

// Break either if a debugger is already attached, or if configured to launch
if (launch || Debugger.IsAttached) {
    if (Debugger.IsAttached || Debugger.Launch())
        Debugger.Break();
}

This also works to debug programs that need elevated privileges, or that need to be able to elevate themselves.

You most likely get this message when the project points to an old location of the assembly where it no longer exists. Since you were able to build it once, the assembly has already been copied into your bin\Debug / bin\Release folders so your project can still find a copy.

If you open the references node of the project in your solution explorer, there should be a yellow icon next to the reference. Remove the reference and add it again from the correct location.

If you want to know the location it was referenced from, you'd have to open the .csproj file in a text editor and look for the HintPath for that assembly - the IDE for some reason does not show this information.

This example shows how to use getopt and eval and HEREDOC and shift to handle short and long parameters with and without a required value that follows. Also the switch/case statement is concise and easy to follow.

#!/usr/bin/env bash

# usage function
function usage()
{
   cat << HEREDOC

   Usage: $progname [--num NUM] [--time TIME_STR] [--verbose] [--dry-run]

   optional arguments:
     -h, --help           show this help message and exit
     -n, --num NUM        pass in a number
     -t, --time TIME_STR  pass in a time string
     -v, --verbose        increase the verbosity of the bash script
     --dry-run            do a dry run, dont change any files

HEREDOC
}  

# initialize variables
progname=$(basename $0)
verbose=0
dryrun=0
num_str=
time_str=

# use getopt and store the output into $OPTS
# note the use of -o for the short options, --long for the long name options
# and a : for any option that takes a parameter
OPTS=$(getopt -o "hn:t:v" --long "help,num:,time:,verbose,dry-run" -n "$progname" -- "$@")
if [ $? != 0 ] ; then echo "Error in command line arguments." >&2 ; usage; exit 1 ; fi
eval set -- "$OPTS"

while true; do
  # uncomment the next line to see how shift is working
  # echo "\$1:\"$1\" \$2:\"$2\""
  case "$1" in
    -h | --help ) usage; exit; ;;
    -n | --num ) num_str="$2"; shift 2 ;;
    -t | --time ) time_str="$2"; shift 2 ;;
    --dry-run ) dryrun=1; shift ;;
    -v | --verbose ) verbose=$((verbose + 1)); shift ;;
    -- ) shift; break ;;
    * ) break ;;
  esac
done

if (( $verbose > 0 )); then

   # print out all the parameters we read in
   cat <<EOM
   num=$num_str
   time=$time_str
   verbose=$verbose
   dryrun=$dryrun
EOM
fi

# The rest of your script below

The most significant lines of the script above are these:

OPTS=$(getopt -o "hn:t:v" --long "help,num:,time:,verbose,dry-run" -n "$progname" -- "$@")
if [ $? != 0 ] ; then echo "Error in command line arguments." >&2 ; exit 1 ; fi
eval set -- "$OPTS"

while true; do
  case "$1" in
    -h | --help ) usage; exit; ;;
    -n | --num ) num_str="$2"; shift 2 ;;
    -t | --time ) time_str="$2"; shift 2 ;;
    --dry-run ) dryrun=1; shift ;;
    -v | --verbose ) verbose=$((verbose + 1)); shift ;;
    -- ) shift; break ;;
    * ) break ;;
  esac
done

Short, to the point, readable, and handles just about everything (IMHO).

Hope that helps someone.

Here's how I solved this issue:

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube://" + video_id));
startActivity(intent);

Now that I've done some more research, it looks like I only needed 'vnd.youtube:VIDEO_ID' instead of two slashes after the colon (':' vs. '://'):

http://it-ride.blogspot.com/2010/04/android-youtube-intent.html

I tried most of the suggestions here and they didn't really work very well with all of the supposed "direct" methods raising exceptions. I would assume that, with my method, if the YouTube app is NOT installed, the OS has a default fallback position of something other than crashing the app. The app is theoretically only going on devices with the YouTube app on them anyway, so this should be a non-issue.

(a–b)/c*(d + e – f / g)

Prefix notation (reverse polish has the operator last, it is unclear which one you meant, but the principle will be exactly the same):

1. (/ f g)
2. (+ d e)
3. (- (+ d e) (/ f g))
4. (- a b)
5. (/ (- a b) c)
6. (* (/ (- a b) c) (- (+ d e) (/ f g)))

I won't write your code but what you looking for is something like a jquery dialog

take a look here

jQuery modal-confirmation

$(function() {
    $( "#dialog-confirm" ).dialog({
      resizable: false,
      height:140,
      modal: true,
      buttons: {
        "Delete all items": function() {
          $( this ).dialog( "close" );
        },
        Cancel: function() {
          $( this ).dialog( "close" );
        }
      }
    });
  });

<div id="dialog-confirm" title="Empty the recycle bin?">
  <p>
    <span class="ui-icon ui-icon-alert" style="float:left; margin:0 7px 20px 0;"></span>
    These items will be permanently deleted and cannot be recovered. Are you sure?
  </p>
</div>

In your setup.py, if you have:

from distutils.core import setup

Then, change it to

from setuptools import setup

Then re-create your virtualenv and re-run the command, and it should work.

Actually i wanted to achieve exactly that in PHP but none of the answers here were very helpful so here's my – pretty straightforward – solution using MySQLi:

// Database variables

$DB_HOST = 'localhost';
$DB_USER = 'root';
$DB_PASS = '1234';

$DB_SRC = 'existing_db';
$DB_DST = 'newly_created_db';



// MYSQL Connect

$mysqli = new mysqli( $DB_HOST, $DB_USER, $DB_PASS ) or die( $mysqli->error );



// Create destination database

$mysqli->query( "CREATE DATABASE $DB_DST" ) or die( $mysqli->error );



// Iterate through tables of source database

$tables = $mysqli->query( "SHOW TABLES FROM $DB_SRC" ) or die( $mysqli->error );

while( $table = $tables->fetch_array() ): $TABLE = $table[0];


    // Copy table and contents in destination database

    $mysqli->query( "CREATE TABLE $DB_DST.$TABLE LIKE $DB_SRC.$TABLE" ) or die( $mysqli->error );
    $mysqli->query( "INSERT INTO $DB_DST.$TABLE SELECT * FROM $DB_SRC.$TABLE" ) or die( $mysqli->error );


endwhile;

To complement the list, also be aware of http://mitmproxy.org/

The best provider for http status code constants is likely to be Jetty's org.eclipse.jetty.http.HttpStatus class because:

• there is a javadoc package in maven which is important if you search for the constant and only know the number -> just open the api docs page and search for the number
• the constants contain the status code number itself.

Only thing I would improve: put the status code number in front of the text description in order to make auto-completion lookup more convient when you are starting with the code.

Your code is indeed using the normal way to create and delete a dynamic object. Yes, it's perfectly normal (and indeed guaranteed by the language standard!) that delete will call the object's destructor, just like new has to invoke the constructor.

If you weren't instantiating Object1 directly but some subclass thereof, I'd remind you that any class intended to be inherited from must have a virtual destructor (so that the correct subclass's destructor can be invoked in cases analogous to this one) -- but if your sample code is indeed representative of your actual code, this cannot be your current problem -- must be something else, maybe in the destructor code you're not showing us, or some heap-corruption in the code you're not showing within that function or the ones it calls...?

BTW, if you're always going to delete the object just before you exit the function which instantiates it, there's no point in making that object dynamic -- just declare it as a local (storage class auto, as is the default) variable of said function!

I didn't knew about Generic methods which could help avoid using Method Overloadding. Below are overloaded methods to print int and double numbers.

    private static void printNumbers(int [] intNumbers)
    { 
        foreach(int element in intNumbers)
        {
            Console.WriteLine(element);
        }

    }

    private static void printNumbers(double[] doubleNumbers)
    {
        foreach (double element in doubleNumbers)
        {
            Console.WriteLine(element);
        }
    }

Generic method which help to have one method for both of the above

    private static void printNumbers<E>(E [] Numbers)
    {
        foreach (E element in Numbers)
        {
            Console.WriteLine(element);
        }
    }

BTW: Converting is highly important if you are serialized, mainly because the de-serialization breaks the type of objects and turns into stdclass, including DateTime objects.

I updated the example of @Jadrovski, now it allows objects and arrays.

example

$stdobj=new StdClass();
$stdobj->field=20;
$obj=new SomeClass();
fixCast($obj,$stdobj);

example array

$stdobjArr=array(new StdClass(),new StdClass());
$obj=array(); 
$obj[0]=new SomeClass(); // at least the first object should indicates the right class.
fixCast($obj,$stdobj);

code: (its recursive). However, i don't know if its recursive with arrays. May be its missing an extra is_array

public static function fixCast(&$destination,$source)
{
    if (is_array($source)) {
        $getClass=get_class($destination[0]);
        $array=array();
        foreach($source as $sourceItem) {
            $obj = new $getClass();
            fixCast($obj,$sourceItem);
            $array[]=$obj;
        }
        $destination=$array;
    } else {
        $sourceReflection = new \ReflectionObject($source);
        $sourceProperties = $sourceReflection->getProperties();
        foreach ($sourceProperties as $sourceProperty) {
            $name = $sourceProperty->getName();
            if (is_object(@$destination->{$name})) {
                fixCast($destination->{$name}, $source->$name);
            } else {
                $destination->{$name} = $source->$name;
            }
        }
    }
}

To prevent inserting a record that exist already. I'd check if the ID value exists in the database. For the example of a Table created with an IDENTITY PRIMARY KEY:

CREATE TABLE [dbo].[Persons] (    
    ID INT IDENTITY(1,1) PRIMARY KEY,
    LastName VARCHAR(40) NOT NULL,
    FirstName VARCHAR(40)
);

When JANE DOE and JOE BROWN already exist in the database.

SET IDENTITY_INSERT [dbo].[Persons] OFF;
INSERT INTO [dbo].[Persons] (FirstName,LastName)
VALUES ('JANE','DOE'); 
INSERT INTO Persons (FirstName,LastName) 
VALUES ('JOE','BROWN');

DATABASE OUTPUT of TABLE [dbo].[Persons] will be:

ID    LastName   FirstName
1     DOE        Jane
2     BROWN      JOE

I'd check if i should update an existing record or insert a new one. As the following JAVA example:

int NewID = 1;
boolean IdAlreadyExist = false;
// Using SQL database connection
// STEP 1: Set property
System.setProperty("java.net.preferIPv4Stack", "true");
// STEP 2: Register JDBC driver
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
// STEP 3: Open a connection
try (Connection conn1 = DriverManager.getConnection(DB_URL, USER,pwd) {
    conn1.setAutoCommit(true);
    String Select = "select * from Persons where  ID = " + ID;
    Statement st1 = conn1.createStatement();
    ResultSet rs1 = st1.executeQuery(Select);
    // iterate through the java resultset
    while (rs1.next()) {
        int ID = rs1.getInt("ID");
        if (NewID==ID) {
            IdAlreadyExist = true;
        }

    }
    conn1.close();
} catch (SQLException e1) {
    System.out.println(e1);
}
if (IdAlreadyExist==false) {
    //Insert new record code here
} else {
    //Update existing record code here
}

If you have tried all of this and still no luck, try the detach/attach again.

In the AndroidManifest.xml, under the application tag, you can set the theme of your choice. To customize the theme, press Ctrl + Click on android:theme = "@style/AppTheme" in the Android manifest file. It will open styles.xml file where you can change the parent attribute of the style tag.

At parent= in styles.xml you can browse all available styles by using auto-complete inside the "". E.g. try parent="Theme." with your cursor right after the . and then pressing Ctrl + Space.

You can also preview themes in the preview window in Android Studio.

This is not possible, as you say, from a security stand point. The only way you could simulate it, is by creating a modeless dialog window.

There are many third-party javascript-plugins that you could use to fake this effect so you do not have to write all that code.

Git introduced a --ff-only option when merging.

From: http://git-scm.com/docs/git-merge

---

--ff-only

Refuse to merge and exit with a non-zero status unless the current HEAD is already up-to-date or the merge can be resolved as a fast-forward.

Doing this will attempt to merge and fast-forward, and if it can't it aborts and prompts you that the fast-forward could not be performed, but leaves your working branch untouched. If it can fast-forward, then it will perform the merge on your working branch. This option is also available on git pull. Thus, you could do the following:

git pull --ff-only origin branchA #See if you can pull down and merge branchA

git merge --ff-only branchA branchB #See if you can merge branchA into branchB

yum install php-mcrypt.x86_64

worked for me instead of

yum install php-mcrypt

$ echo "bar embarassment"|awk '{for(o=1;o<=NF;o++)if($o=="bar")$o="no bar"}1'
no bar embarassment

ser.read(64) should be ser.read(size=64); ser.read uses keyword arguments, not positional.

Also, you're reading from the port twice; what you probably want to do is this:

i=0
for modem in PortList:
    for port in modem:
        try:
            ser = serial.Serial(port, 9600, timeout=1)
            ser.close()
            ser.open()
            ser.write("ati")
            time.sleep(3)
            read_val = ser.read(size=64)
            print read_val
            if read_val is not '':
                print port
        except serial.SerialException:
            continue
        i+=1

DATE: It is used for values with a date part but no time part. MySQL retrieves and displays DATE values in YYYY-MM-DD format. The supported range is 1000-01-01 to 9999-12-31.

DATETIME: It is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in YYYY-MM-DD HH:MM:SS format. The supported range is 1000-01-01 00:00:00 to 9999-12-31 23:59:59.

TIMESTAMP: It is also used for values that contain both date and time parts, and includes the time zone. TIMESTAMP has a range of 1970-01-01 00:00:01 UTC to 2038-01-19 03:14:07 UTC.

TIME: Its values are in HH:MM:SS format (or HHH:MM:SS format for large hours values). TIME values may range from -838:59:59 to 838:59:59. The hours part may be so large because the TIME type can be used not only to represent a time of day (which must be less than 24 hours), but also elapsed time or a time interval between two events (which may be much greater than 24 hours, or even negative).

You can try this:

<div ng-app="app">
    <div ng-controller="AppCtrl">
        <a my-dir ng-repeat="user in users" ng-click="fxn()">{{user.name}}</a>
    </div>
</div>

<script>
var app = angular.module('app', []);

function AppCtrl($scope) {
        $scope.users = [{ name: 'John', id: 1 }, { name: 'anonymous' }];
        $scope.fxn = function () {
            alert('It works');
        };
    }

app.directive("myDir", function ($compile) {
    return {
        scope: {ngClick: '='}
    };
});
</script>

Alternative approach if .htaccess customization is not ideal option:

I've created simple redirect server for public use. Just add A or CNAME record:

CNAME   r.simpleredirect.net
A       89.221.218.22

More info: https://simpleredirect.net

the second subscript operator is invalid here. You passed a int * pointer into function, which is a 1-d array. So only one subscript operator can be used on it.

Solution : you can pass int ** pointer into funciton

Do you mean like?

It seems that the most common method of achieving this is to draw a GPolygon with enough points to simulate a circle. The example you referenced uses this method. This page has a good example - look for the function drawCircle in the source code.

If your list is very big and you are filtering repeatedly - you can sort the original list on the filter attribute, binary search to find the start and end points.

Initial time O(n*log(n)) then O(log(n)).

Standard filtering will take O(n) each time.

Just in case you want the binary representation and you're still drunk from last night's party:

private static string ByteToString(int value)
{
    StringBuilder builder = new StringBuilder(sizeof(byte) * 8);
    BitArray[] bitArrays = BitConverter.GetBytes(value).Reverse().Select(b => new BitArray(new []{b})).ToArray();
    foreach (bool bit in bitArrays.SelectMany(bitArray => bitArray.Cast<bool>().Reverse()))
    {
        builder.Append(bit ? '1' : '0');
    }
    return builder.ToString();
}

Note: Something about not handling endianness very nicely...

If you don't mind sacrificing a bit of memory for speed, you can use below to generate an array with pre-calculated string values:

static void OutputIntegerStringRepresentations()
{
    Console.WriteLine("private static string[] integerAsDecimal = new [] {");
    for (int i = int.MinValue; i < int.MaxValue; i++)
    {
        Console.WriteLine("\t\"{0}\",", i);
    }
    Console.WriteLine("\t\"{0}\"", int.MaxValue);
    Console.WriteLine("}");
}

Like all of us, you are another victim of asynchronous I/O. With asynchronous calls, if you loop around a lot of files, Node.js will start to open a file descriptor for each file to read and then will wait for action until you close it.

File descriptor remains open until resource is available on your server to read it. Even if your files are small and reading or updating is fast, it takes some time, but in the same time your loop don't stop to open new files descriptor. So if you have too many files, the limit will be soon reached and you get a beautiful EMFILE.

There is one solution, creating a queue to avoid this effect.

Thanks to people who wrote Async, there is a very useful function for that. There is a method called Async.queue, you create a new queue with a limit and then add filenames to the queue.

Note: If you have to open many files, it would be a good idea to store which files are currently open and don't reopen them infinitely.

const fs = require('fs')
const async = require("async")

var q = async.queue(function(task, callback) {
    console.log(task.filename);
    fs.readFile(task.filename,"utf-8",function (err, data_read) {
            callback(err,task.filename,data_read);
        }
    );
}, 4);

var files = [1,2,3,4,5,6,7,8,9,10]

for (var file in files) {
    q.push({filename:file+".txt"}, function (err,filename,res) {
        console.log(filename + " read");
    });
}

You can see that each file is added to the queue (console.log filename), but only when the current queue is under the limit you set previously.

async.queue get information about availability of the queue through a callback, this callback is called only when data file is read and any action you have to do is achieved. (see fileRead method)

So you cannot be overwhelmed by files descriptor.

> node ./queue.js

    1.txt

The xts package provides a last function:

library(xts)
a <- 1:100
last(a)
[1] 100

Have you tried using a icon font like http://fortawesome.github.io/Font-Awesome/

Bootstrap comes with their own library, but it doesn't have as many icons as Font Awesome.

You can use:

if (myString1.IndexOf("AbC", StringComparison.OrdinalIgnoreCase) >=0) {
    //...
}

This works with any .NET version.

This error message can be thrown in the application logs when the actual issue is that the oracle database server ran out of space.

After correcting the space issue, this particular error message disappeared.

You have too many redundant nested arrays inside your jSON data, but it is possible to retrieve the information. Though like others have said you might want to clean it up.

use each() wrap within another each() until the last array.

for result.data[0].stuff[0].onetype[0] in jQuery you could do the following:

`

$.each(data.result.data, function(index0, v) {
    $.each(v, function (index1, w) {
        $.each(w, function (index2, x) {
            alert(x.id);
        });
    });

});

`

You can use too

style="overflow-y: scroll; height:150px; width: auto;"

It's works for me

From a quick read of the previous answers, they look correct, but it doesn't look like anyone mentioned the new configuration facilities in Visual Studio 2008. It still uses app.config (copied at compile time to YourAppName.exe.config), but there is a UI widget to set properties and specify their types. Double-click Settings.settings in your project's "Properties" folder.

The best part is that accessing this property from code is typesafe - the compiler will catch obvious mistakes like mistyping the property name. For example, a property called MyConnectionString in app.config would be accessed like:

string s = Properties.Settings.Default.MyConnectionString;

In order to create an anonymous type (or any type) with a property that has a reserved keyword as its name in C#, you can prepend the property name with an at sign, @:

Html.BeginForm("Foo", "Bar", FormMethod.Post, new { @class = "myclass"})

For VB.NET this syntax would be accomplished using the dot, ., which in that language is default syntax for all anonymous types:

Html.BeginForm("Foo", "Bar", FormMethod.Post, new with { .class = "myclass" })

Try this:

foreach($array as $k => $obj) { 
    $obj->{'newKey'} = "value"; 
}

I have experienced the same issue before. In my case, I needed to install php-mbstring extension on GoDaddy VPS server. None of above solutions did work for me.

What I've found is to install PHP extensions using WHM (Web Hosting Manager) of GoDaddy. Anyone who use GoDaddy VPS server can access this page with the following address.

http://{Your_Server_IP_Address}:2087

On this page, you can easily find Easy Apache software that can help you to install/upgrade php components and extensions. You can select currently installed profile and customize and then provision the profile. Everything with Easy Apache is explanatory.

I remember that I did very similar things for HostGator server, but I don't remember how actually I did for profile update.

Edit: When you have got the server which supports Web Hosting Manager, then you can add/update/remove php extensions on WHM. On godaddy servers, it's even recommended to update PHP ini settings on WHM.

Note that this can happen even when the user has NOT bookmarked the site to their iOS home screen - for example, any time you open a page using Chrome for iOS, it does a GET "/apple-touch-icon-precomposed.png".

I've handled this and other non-HTML 404 requests in my ApplicationController as follows:

respond_to do |format|
  format.html { render :template => "error_404", :layout => "errors", :status => 404 }
  format.all { render :nothing => true, :status => 404 }
end

The format.all response takes care of images such as this PNG file (which does not exist for my site).

Once I'd discovered all the information of how my client was handling the encryption/decryption at their end it was straight forward using the AesManaged example suggested by dtb.

The finally implemented code started like this:

    try
    {
        // Create a new instance of the AesManaged class.  This generates a new key and initialization vector (IV).
        AesManaged myAes = new AesManaged();

        // Override the cipher mode, key and IV
        myAes.Mode = CipherMode.ECB;
        myAes.IV = new byte[16] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; // CRB mode uses an empty IV
        myAes.Key = CipherKey;  // Byte array representing the key
        myAes.Padding = PaddingMode.None;

        // Create a encryption object to perform the stream transform.
        ICryptoTransform encryptor = myAes.CreateEncryptor();

        // TODO: perform the encryption / decryption as required...

    }
    catch (Exception ex)
    {
        // TODO: Log the error 
        throw ex;
    }

OpenId - Used only for Authentication.

OAuth - Used for both Authentication and Authorization. Authorization depends on the access_token which comes as part of JWT token. It can have details of user permissions or any useful information.

Both can rely on 3rd party auth provider which maintains their accounts. For example OKTA identity provider, User provides the credentials on OKTA login page and on successful login the user is redirected on the consumer application with the JWT token in the header.

The approach I've found workable is git's submodule system. Using that you can submodule in a given version of the code and upgrading/downgrading is explicit and recorded - never haphazard.

The folder structure I've taken with this is:

+ myproject
++ src
+++ myproject
+++ github.com
++++ submoduled_project of some kind.

for me worked changing the filesystem from Read-Only before running vim:

bash-3.2# mount -o remount rw /

1) Go to C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A for VS2013

2) Copy the folders Include and Lib (you should check where are your folders in folder windows such as v7.1, v8, v6, etc.)

3) Paste them into C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC

I solved my problems like:

error lnk1104: cannot open file 'kernel32.lib'.
error c1083: Cannot open Windows.h

Thanks.

I had a similar problem, was trying to use the FIND_IN_SET procedure with a string variable.

SET @my_var = 'string1,string2';
SELECT * from my_table WHERE FIND_IN_SET(column_name,@my_var);

and was receiving the error

Error Code: 1267. Illegal mix of collations (utf8_unicode_ci,IMPLICIT) and (utf8_general_ci,IMPLICIT) for operation 'find_in_set'

Short answer:

No need to change any collation_YYYY variables, just add the correct collation next to your variable declaration, i.e.

SET @my_var = 'string1,string2' COLLATE utf8_unicode_ci;
SELECT * from my_table WHERE FIND_IN_SET(column_name,@my_var);

Long answer:

I first checked the collation variables:

mysql> SHOW VARIABLES LIKE 'collation%';
    +----------------------+-----------------+
    | Variable_name        | Value           |
    +----------------------+-----------------+
    | collation_connection | utf8_general_ci |
    +----------------------+-----------------+
    | collation_database   | utf8_general_ci |
    +----------------------+-----------------+
    | collation_server     | utf8_general_ci |
    +----------------------+-----------------+

Then I checked the table collation:

mysql> SHOW CREATE TABLE my_table;

CREATE TABLE `my_table` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `column_name` varchar(40) COLLATE utf8_unicode_ci DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=125 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

This means that my variable was configured with the default collation of utf8_general_ci while my table was configured as utf8_unicode_ci.

By adding the COLLATE command next to the variable declaration, the variable collation matched the collation configured for the table.

Could you run a checksum of some sort on the result and store that locally? Then when your application queries the database, you can compare its checksum and determine if you should import it?

It looks like you may be able to use the ORA_HASH function to accomplish this.

Update: Another good resource: 10g’s ORA_HASH function to determine if two Oracle tables’ data are equal

"Add a reference to MySql.Data.dll" means you need to add a library reference to the downloaded connector. The IDE will link the database connection library with your application when it compiles.

Step-by-Step Example

I downloaded the binary (no installer) zip package from the MySQL web site, extracted onto the desktop, and did the following:

1. Create a new project in Visual Studio
2. In the Solution Explorer, under the project name, locate References and right-click on it. Select "Add Reference".
3. In the "Add Reference" dialog, switch to the "Browse" tab and browse to the folder containing the downloaded connector. Navigate to the "bin" folder, and select the "MySql.Data.dll" file. Click OK.
4. At the top of your code, add using MySql.Data.MySqlClient;. If you've added the reference correctly, IntelliSense should offer to complete this for you.

Once you pass the assembly instance back to the caller domain, the caller domain will try to load it! This is why you get the exception. This happens in your last line of code:

domain.Load(AssemblyName.GetAssemblyName(path));

Thus, whatever you want to do with the assembly, should be done in a proxy class - a class which inherit MarshalByRefObject.

Take in count that the caller domain and the new created domain should both have access to the proxy class assembly. If your issue is not too complicated, consider leaving the ApplicationBase folder unchanged, so it will be same as the caller domain folder (the new domain will only load Assemblies it needs).

In simple code:

public void DoStuffInOtherDomain()
{
    const string assemblyPath = @"[AsmPath]";
    var newDomain = AppDomain.CreateDomain("newDomain");
    var asmLoaderProxy = (ProxyDomain)newDomain.CreateInstanceAndUnwrap(Assembly.GetExecutingAssembly().FullName, typeof(ProxyDomain).FullName);

    asmLoaderProxy.GetAssembly(assemblyPath);
}

class ProxyDomain : MarshalByRefObject
{
    public void GetAssembly(string AssemblyPath)
    {
        try
        {
            Assembly.LoadFrom(AssemblyPath);
            //If you want to do anything further to that assembly, you need to do it here.
        }
        catch (Exception ex)
        {
            throw new InvalidOperationException(ex.Message, ex);
        }
    }
}

If you do need to load the assemblies from a folder which is different than you current app domain folder, create the new app domain with specific dlls search path folder.

For example, the app domain creation line from the above code should be replaced with:

var dllsSearchPath = @"[dlls search path for new app domain]";
AppDomain newDomain = AppDomain.CreateDomain("newDomain", new Evidence(), dllsSearchPath, "", true);

This way, all the dlls will automaically be resolved from dllsSearchPath.

Use forward slashes to specify the UNC Path:

open('//HOST/share/path/to/file')

(if your Python client code is also running under Windows)

Spend a whole week, after all the following setting worked ! and finally saved. Removing the UrlScan from ISAPI fileters in IIS fixes the problem in our case

As an alternative, StringUtils from Apache Commons can be used.

 byte[] bytes = {(byte) 1};
 String convertedString = StringUtils.newStringUtf8(bytes);

or

 String myString = "example";
 byte[] convertedBytes = StringUtils.getBytesUtf8(myString);

If you have non-standard charset, you can use getBytesUnchecked() or newString() accordingly.

And here's a way to do it with PrototypeJS:

Event.observe(window, 'load', function(event) {
    // Do stuff
});

The ternary operator can only be the right side of an assignment and not a statement of its own.

/dev/null is a standard file that discards all you write to it, but reports that the write operation succeeded.

1 is standard output and 2 is standard error.

2>&1 redirects standard error to standard output. &1 indicates file descriptor (standard output), otherwise (if you use just 1) you will redirect standard error to a file named 1. [any command] >>/dev/null 2>&1 redirects all standard error to standard output, and writes all of that to /dev/null.

getUserVisibleHint() comes as true only when the fragment is on the view and visible

If you can't use JodaTime, you can do the following:

Calendar startCalendar = new GregorianCalendar();
startCalendar.setTime(startDate);
Calendar endCalendar = new GregorianCalendar();
endCalendar.setTime(endDate);

int diffYear = endCalendar.get(Calendar.YEAR) - startCalendar.get(Calendar.YEAR);
int diffMonth = diffYear * 12 + endCalendar.get(Calendar.MONTH) - startCalendar.get(Calendar.MONTH);

Note that if your dates are 2013-01-31 and 2013-02-01, you get a distance of 1 month this way, which may or may not be what you want.

Simply by "unpacking" the list in the print function argument and using a newline (\n) as separator.

print(*lst, sep='\n')

lst = ['foo', 'bar', 'spam', 'egg']
print(*lst, sep='\n')

foo
bar
spam
egg

Specifying the columns on your query should do the trick:

select a.col1, b.col2, a.col3, b.col4, a.category_id 
from items_a a, items_b b 
where a.category_id = b.category_id

should do the trick with regards to picking the columns you want.

To get around the fact that some data is only in items_a and some data is only in items_b, you would be able to do:

select 
  coalesce(a.col1, b.col1) as col1, 
  coalesce(a.col2, b.col2) as col2,
  coalesce(a.col3, b.col3) as col3,
  a.category_id
from items_a a, items_b b
where a.category_id = b.category_id

The coalesce function will return the first non-null value, so for each row if col1 is non null, it'll use that, otherwise it'll get the value from col2, etc.

I am on mingw bash, so I have created ~.profile file with following: alias atom='~/AppData/Local/atom/bin/atom'

You can use the apply function of the Series object:

>>> df = pd.DataFrame([['  a  ', 10], ['  c  ', 5]])
>>> df[0][0]
'  a  '
>>> df[0] = df[0].apply(lambda x: x.strip())
>>> df[0][0]
'a'

Note the usage of strip and not the regex which is much faster

Another option - use the apply function of the DataFrame object:

>>> df = pd.DataFrame([['  a  ', 10], ['  c  ', 5]])
>>> df.apply(lambda x: x.apply(lambda y: y.strip() if type(y) == type('') else y), axis=0)

   0   1
0  a  10
1  c   5

Bootstrap 4.0

Be aware of all migration changes from Bootstrap 3 to 4. On the table you now need to enable flex box by adding the class d-flex, and drop the xs to allow bootstrap to automatically detect the viewport.

<div class="container-fluid">
    <table id="productSizes" class="table">
        <thead>
            <tr class="d-flex">
                <th class="col-1">Size</th>
                <th class="col-3">Bust</th>
                <th class="col-3">Waist</th>
                <th class="col-5">Hips</th>
            </tr>
        </thead>
        <tbody>
            <tr class="d-flex">
                <td class="col-1">6</td>
                <td class="col-3">79 - 81</td>
                <td class="col-3">61 - 63</td>
                <td class="col-5">89 - 91</td>
            </tr>

Bootstrap 3.2

Table column width use the same layout as grids do; using col-[viewport]-[size]. Remember the column sizes should total 12; 1 + 3 + 3 + 5 = 12 in this example.

        <thead>
            <tr>
                <th class="col-xs-1">Size</th>
                <th class="col-xs-3">Bust</th>
                <th class="col-xs-3">Waist</th>
                <th class="col-xs-5">Hips</th>
            </tr>
        </thead>

Remember to set the <th> elements rather than the <td> elements so it sets the whole column. Here is a working BOOTPLY.

Thanks to @Dan for reminding me to always work mobile view (col-xs-*) first.

This should work, I tried it by myself and it worked for me. If you pass True instead of false, the print dialog will appear.

this.print(false);

Your regex pattern needs to be in delimiters:

$numpattern="/^([0-9]+)$/";

AFAIK the delay method only works for numeric CSS modifications.

For other purposes JavaScript comes with a setTimeout method:

window.setTimeout(function(){$("#div").removeClass("error");}, 1000);

<div>
    <h1> Ok </h1>
    <button type='button'>Button</button>
    <div style="clear:both;"></div>
</div>

css

div {
    background: purple;
}

div h1 {
    text-align: center;
}

div button {
    float: right;
    margin-right:10px;

}

i) what is the difference between these two objects

The simple answer is that [object] indicates a host object that has no internal class. A host object is an object that is not part of the ECMAScript implementation you're working with, but is provided by the host as an extension. The DOM is a common example of host objects, although in most newer implementations DOM objects inherit from the native Object and have internal class names (such as HTMLElement, Window, etc). IE's proprietary ActiveXObject is another example of a host object.

[object] is most commonly seen when alerting DOM objects in Internet Explorer 7 and lower, since they are host objects that have no internal class name.

ii) what type of Object is this

You can get the "type" (internal class) of object using Object.prototype.toString. The specification requires that it always returns a string in the format [object [[Class]]], where [[Class]] is the internal class name such as Object, Array, Date, RegExp, etc. You can apply this method to any object (including host objects), using

Object.prototype.toString.apply(obj);

Many isArray implementations use this technique to discover whether an object is actually an array (although it's not as robust in IE as it is in other browsers).

iii) what all properties does this object contains and values of each property

In ECMAScript 3, you can iterate over enumerable properties using a for...in loop. Note that most built-in properties are non-enumerable. The same is true of some host objects. In ECMAScript 5, you can get an array containing the names of all non-inherited properties using Object.getOwnPropertyNames(obj). This array will contain non-enumerable and enumerable property names.

Eureka moment!

I have had this error before.

Did you invoke the perl debugger with something like :-

perl -d yourprog.pl > log.txt

If so whats going on is perl debug tries to query and perhaps reset the terminal width. When stdout is not a terminal this fails with the IOCTL message.

The alternative would be for your debug session to hang forever because you did not see the prompt for instructions.

You are not getting value of $id=$_GET['id'];

And you are using it (before it gets initialised).

Use php's in built isset() function to check whether the variable is defied or not.

So, please update the line to:

$id = isset($_GET['id']) ? $_GET['id'] : '';

The command that worked in my case was:

xsd /c your.xsd 

Many distinctions have already been mentioned. Here is one more:

Running npm install at the top of your source directory will run various scripts: prepublish, preinstall, install, postinstall. Depending on what these scripts do, a npm install may do considerably more work than just installing dependencies.

I've just had a use case where prepublish would call make and the Makefile was designed to fetch dependencies if the package.json got updated. Calling npm install from within the Makefile would have lead to an infinite recursion, while calling npm update worked just fine, installing all dependencies so that the build could proceed even if make was called directly.

On (mostly) old processors, multiplying by 31 can be relatively cheap. On an ARM, for instance, it is only one instruction:

RSB       r1, r0, r0, ASL #5    ; r1 := - r0 + (r0<<5)

Most other processors would require a separate shift and subtract instruction. However, if your multiplier is slow this is still a win. Modern processors tend to have fast multipliers so it doesn't make much difference, so long as 32 goes on the correct side.

It's not a great hash algorithm, but it's good enough and better than the 1.0 code (and very much better than the 1.0 spec!).

Windows 8 follow these 3 steps:

1. Locate eclipse file.
2. create shortcut on desktop.
3. Double click on the eclipse shortcut to open the application.

Some answers seem just wrong,

1. you can't use dictionary how would store the pairs (a,b) and (a,c). Pairs concept should not be confused with associative look up of key and values
2. lot of the above code seems suspect

Here is my pair class

public class Pair<X, Y>
{
    private X _x;
    private Y _y;

    public Pair(X first, Y second)
    {
        _x = first;
        _y = second;
    }

    public X first { get { return _x; } }

    public Y second { get { return _y; } }

    public override bool Equals(object obj)
    {
        if (obj == null)
            return false;
        if (obj == this)
            return true;
        Pair<X, Y> other = obj as Pair<X, Y>;
        if (other == null)
            return false;

        return
            (((first == null) && (other.first == null))
                || ((first != null) && first.Equals(other.first)))
              &&
            (((second == null) && (other.second == null))
                || ((second != null) && second.Equals(other.second)));
    }

    public override int GetHashCode()
    {
        int hashcode = 0;
        if (first != null)
            hashcode += first.GetHashCode();
        if (second != null)
            hashcode += second.GetHashCode();

        return hashcode;
    }
}

Here is some test code:

[TestClass]
public class PairTest
{
    [TestMethod]
    public void pairTest()
    {
        string s = "abc";
        Pair<int, string> foo = new Pair<int, string>(10, s);
        Pair<int, string> bar = new Pair<int, string>(10, s);
        Pair<int, string> qux = new Pair<int, string>(20, s);
        Pair<int, int> aaa = new Pair<int, int>(10, 20);

        Assert.IsTrue(10 == foo.first);
        Assert.AreEqual(s, foo.second);
        Assert.AreEqual(foo, bar);
        Assert.IsTrue(foo.GetHashCode() == bar.GetHashCode());
        Assert.IsFalse(foo.Equals(qux));
        Assert.IsFalse(foo.Equals(null));
        Assert.IsFalse(foo.Equals(aaa));

        Pair<string, string> s1 = new Pair<string, string>("a", "b");
        Pair<string, string> s2 = new Pair<string, string>(null, "b");
        Pair<string, string> s3 = new Pair<string, string>("a", null);
        Pair<string, string> s4 = new Pair<string, string>(null, null);
        Assert.IsFalse(s1.Equals(s2));
        Assert.IsFalse(s1.Equals(s3));
        Assert.IsFalse(s1.Equals(s4));
        Assert.IsFalse(s2.Equals(s1));
        Assert.IsFalse(s3.Equals(s1));
        Assert.IsFalse(s2.Equals(s3));
        Assert.IsFalse(s4.Equals(s1));
        Assert.IsFalse(s1.Equals(s4));
    }
}

I have searched for a solution that will visualize process steps in my web application. I have found the following excellent write-up by Stephen A Thomas:

Tracking Progress in Pure CSS (Original Link now dead)

In his approach Thomas even gets away with just using CSS - no Javascript! In an essence the following CSS code from his article does the trick for me:

    <style>

    <!-- Progress with steps -->

    ol.progtrckr {
        margin: 0;
        padding: 0;
        list-style-type: none;
    }

    ol.progtrckr li {
        display: inline-block;
        text-align: center;
        line-height: 3em;
    }

    ol.progtrckr[data-progtrckr-steps="2"] li { width: 49%; }
    ol.progtrckr[data-progtrckr-steps="3"] li { width: 33%; }
    ol.progtrckr[data-progtrckr-steps="4"] li { width: 24%; }
    ol.progtrckr[data-progtrckr-steps="5"] li { width: 19%; }
    ol.progtrckr[data-progtrckr-steps="6"] li { width: 16%; }
    ol.progtrckr[data-progtrckr-steps="7"] li { width: 14%; }
    ol.progtrckr[data-progtrckr-steps="8"] li { width: 12%; }
    ol.progtrckr[data-progtrckr-steps="9"] li { width: 11%; }

    ol.progtrckr li.progtrckr-done {
        color: black;
        border-bottom: 4px solid yellowgreen;
    }
    ol.progtrckr li.progtrckr-todo {
        color: silver; 
        border-bottom: 4px solid silver;
    }

    ol.progtrckr li:after {
        content: "\00a0\00a0";
    }
    ol.progtrckr li:before {
        position: relative;
        bottom: -2.5em;
        float: left;
        left: 50%;
        line-height: 1em;
    }
    ol.progtrckr li.progtrckr-done:before {
        content: "\2713";
        color: white;
        background-color: yellowgreen;
        height: 1.2em;
        width: 1.2em;
        line-height: 1.2em;
        border: none;
        border-radius: 1.2em;
    }
    ol.progtrckr li.progtrckr-todo:before {
        content: "\039F";
        color: silver;
        background-color: white;
        font-size: 1.5em;
        bottom: -1.6em;
    }

</style>

As well as HTML tags from his example (I use Grails GSP pages to generate tags and 'done/todo' class dynamically):

<ol class="progtrckr" data-progtrckr-steps="5">
    <li class="progtrckr-done">Order Processing</li>
    <li class="progtrckr-done">Pre-Production</li>
    <li class="progtrckr-done">In Production</li>
    <li class="progtrckr-done">Shipped</li>
    <li class="progtrckr-todo">Delivered</li>
</ol>

Hope it helps. Works pretty well for me.

UPDATE: The following (shortened) version also works well.

    ol.progtrckr {
        display: table;
        list-style-type: none;
        margin: 0;
        padding: 0;
        table-layout: fixed;
        width: 100%;
    }
    ol.progtrckr li {
        display: table-cell;
        text-align: center;
        line-height: 3em;
    }
    ... and the rest of the CSS ...

    <ol class="progtrckr">
        ...
    </ol>

display: table; table-layout: fixed; width: 100% ensure that the list items are automatically sized equally as long as the content does not overflow. There is no need to use data-progtrckr-steps and its associated CSS.

Assuming your dataframe is mydf:

mydf$task <- factor(mydf$task, levels = c("up", "down", "left", "right", "front", "back"))

I'm surprised this wasn't mentioned yet...

here are a couple of additional variations using this['var_name']

the benefit of using this method that it can be used before a variable is defined.

if (this['elem']) {...}; // less safe than the res but works as long as you're note expecting a falsy value
if (this['elem'] !== undefined) {...}; // check if it's been declared
if (this['elem'] !== undefined && elem !== null) {...}; // check if it's not null, you can use just elem for the second part

// these will work even if you have an improper variable definition declared here
elem = null; // <-- no var here!! BAD!

I really don't understand why python still doesn't have such a function. I also don't agree to use the following

f.tell() == os.fstat(f.fileno()).st_size

The main reason is f.tell() doesn't likely to work for some special conditions.

The method works for me is like the following. If you have some pseudocode like the following

while not EOF(f):
     line = f.readline()
     " do something with line"

You can replace it with:

lines = iter(f.readlines())
while True:
     try:
        line = next(lines)
        " do something with line"
     except StopIteration:
        break

This method is simple and you don't need to change most of you code.

This code worked nicely for me, thanks.

This is what i did with it. Some methods for stepping forward or backwards and one for going directly to a particular page. Its for a 6 page document in portrait view. It will work ok if you paste it into the implementation of the RootController of the pageViewController template.

-(IBAction)pageGoto:(id)sender {

    //get page to go to
    NSUInteger pageToGoTo = 4;

    //get current index of current page
    DataViewController *theCurrentViewController = [self.pageViewController.viewControllers   objectAtIndex:0];
    NSUInteger retreivedIndex = [self.modelController indexOfViewController:theCurrentViewController];

    //get the page(s) to go to
    DataViewController *targetPageViewController = [self.modelController viewControllerAtIndex:(pageToGoTo - 1) storyboard:self.storyboard];

    DataViewController *secondPageViewController = [self.modelController viewControllerAtIndex:(pageToGoTo) storyboard:self.storyboard];

    //put it(or them if in landscape view) in an array
    NSArray *theViewControllers = nil;    
    theViewControllers = [NSArray arrayWithObjects:targetPageViewController, secondPageViewController, nil];


    //check which direction to animate page turn then turn page accordingly
    if (retreivedIndex < (pageToGoTo - 1) && retreivedIndex != (pageToGoTo - 1)){
        [self.pageViewController setViewControllers:theViewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];
    }

    if (retreivedIndex > (pageToGoTo - 1) && retreivedIndex != (pageToGoTo - 1)){
        [self.pageViewController setViewControllers:theViewControllers direction:UIPageViewControllerNavigationDirectionReverse animated:YES completion:NULL];
    }

}


-(IBAction)pageFoward:(id)sender {

    //get current index of current page
    DataViewController *theCurrentViewController = [self.pageViewController.viewControllers objectAtIndex:0];
    NSUInteger retreivedIndex = [self.modelController indexOfViewController:theCurrentViewController];

    //check that current page isn't first page
    if (retreivedIndex < 5){

        //get the page to go to
        DataViewController *targetPageViewController = [self.modelController viewControllerAtIndex:(retreivedIndex + 1) storyboard:self.storyboard];

        //put it(or them if in landscape view) in an array
        NSArray *theViewControllers = nil;    
        theViewControllers = [NSArray arrayWithObjects:targetPageViewController, nil];

        //add page view
        [self.pageViewController setViewControllers:theViewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];

    }

}


-(IBAction)pageBack:(id)sender {


    //get current index of current page
    DataViewController *theCurrentViewController = [self.pageViewController.viewControllers objectAtIndex:0];
    NSUInteger retreivedIndex = [self.modelController indexOfViewController:theCurrentViewController];

    //check that current page isn't first page
    if (retreivedIndex > 0){

    //get the page to go to
    DataViewController *targetPageViewController = [self.modelController viewControllerAtIndex:(retreivedIndex - 1) storyboard:self.storyboard];

    //put it(or them if in landscape view) in an array
    NSArray *theViewControllers = nil;    
    theViewControllers = [NSArray arrayWithObjects:targetPageViewController, nil];

    //add page view
    [self.pageViewController setViewControllers:theViewControllers direction:UIPageViewControllerNavigationDirectionReverse animated:YES completion:NULL];

    }

}

When you have an assignment operator in a statement, the LHS of the operator must be something the language calls an lvalue. If the LHS of the operator does not evaluate to an lvalue, the value from the RHS cannot be assigned to the LHS.

You cannot use:

10 = 20;

since 10 does not evaluate to an lvalue.

You can use:

int i;
i = 20;

since i does evaluate to an lvalue.

You cannot use:

int i;
i + 1 = 20;

since i + 1 does not evaluate to an lvalue.

In your case, p + 1 does not evaluate to an lavalue. Hence, you cannot use

p + 1 = p;

EDIT: The below answer no longer works see here

Google Chrome cache file format description.

Cache files list, see URLs (copy and paste to your browser address bar):

• chrome://cache/
• chrome://view-http-cache/

Cache folder in Linux: $~/.cache/google-chrome/Default/Cache

Let's determine in file GZIP encoding:

$ head f84358af102b1064_0 | hexdump -C | grep --before-context=100 --after-context=5 "1f 8b 08"

Extract Chrome cache file by one line on PHP (without header, CRC32 and ISIZE block):

$ php -r "echo gzinflate(substr(strchr(file_get_contents('f84358af102b1064_0'), \"\x1f\x8b\x08\"), 10,
-8));"

Look at ?par for the various graphics parameters.

In general cex controls size, col controls colour. If you want to control the colour of a label, the par is col.lab, the colour of the axis annotations col.axis, the colour of the main text, col.main etc. The names are quite intuitive, once you know where to begin.

For example

x <- 1:10
y <- 1:10

plot(x , y,xlab="x axis", ylab="y axis",  pch=19, col.axis = 'blue', col.lab = 'red', cex.axis = 1.5, cex.lab = 2)

If you need to change the colour / style of the surrounding box and axis lines, then look at ?axis or ?box, and you will find that you will be using the same parameter names within calls to box and axis.

You have a lot of control to make things however you wish.

eg

plot(x , y,xlab="x axis", ylab="y axis",  pch=19,  cex.lab = 2, axes = F,col.lab = 'red')
box(col = 'lightblue')
axis(1, col = 'blue', col.axis = 'purple', col.ticks = 'darkred', cex.axis = 1.5, font = 2, family = 'serif')
axis(2, col = 'maroon', col.axis = 'pink', col.ticks = 'limegreen', cex.axis = 0.9, font =3, family = 'mono')

Which is seriously ugly, but shows part of what you can control

Put double quotes around the path that has spaces like this:

REGSVR32 "E:\Documents and Settings\All Users\Application Data\xyz.dll"

This is what I normally use when I need to pad a value.

SET @PaddedValue = REPLICATE('0', @Length - LEN(@OrigValue)) + CAST(@OrigValue as VARCHAR)

This is over simplifying it, but Express.js is to Node.js what Ruby on Rails or Sinatra is to Ruby.

Express 3.x is a light-weight web application framework to help organize your web application into an MVC architecture on the server side. You can use a variety of choices for your templating language (like EJS, Jade, and Dust.js).

You can then use a database like MongoDB with Mongoose (for modeling) to provide a backend for your Node.js application. Express.js basically helps you manage everything, from routes, to handling requests and views.

Redis is a key/value store -- commonly used for sessions and caching in Node.js applications. You can do a lot more with it, but that's what I'm using it for. I use MongoDB for more complex relationships, like line-item <-> order <-> user relationships. There are modules (most notably connect-redis) that will work with Express.js. You will need to install the Redis database on your server.

Here is a link to the Express 3.x guide: https://expressjs.com/en/3x/api.html

This is validation of domain name in javascript:

<script>
function frmValidate() {
 var val=document.frmDomin.name.value;
 if (/^[a-zA-Z0-9][a-zA-Z0-9-]{1,61}[a-zA-Z0-9](?:\.[a-zA-Z]{2,})+$/.test(val)){
      alert("Valid Domain Name");
      return true;
 } else {
      alert("Enter Valid Domain Name");
      val.name.focus();
      return false;
 }
}
</script>

select C.ComputerName, S.Version, A.Name from Computer C inner join Software_Computer SC on C.Id = SC.ComputerId Inner join Software S on SC.SoftwareID = S.Id Inner join Application A on S.ApplicationId = A.Id ;

I'd suggest following a few debugging steps.

First run the query directly against the DB. Confirm it is bringing results back. Even with something as simple as this you can find you've made a mistake, or the table is empty, or somesuch oddity.

If the above is ok, then try looping and echoing out the contents of $row just directly into the HTML to see what you've getting back in the mysql_query - see if it matches what you got directly in the DB.

If your data is output onto the page, then look at what's going wrong in your HTML formatting.

However, if nothing is output from $row, then figure out why the mysql_query isn't working e.g. does the user have permission to query that DB, do you have an open DB connection, can the webserver connect to the DB etc [something on these lines can often be a gotcha]

Changing your query slightly to

$sql = mysql_query("SELECT username FROM users") or die(mysql_error());  

may help to highlight any errors: php manual

This is a security update. If an attacker can modify some file in the web server (the JS one, for example), he can make every loaded pages to download another script (for example to keylog your password or steal your SessionID and send it to his own server).

To avoid it, the browser check the Same-origin policy

Your problem is that the browser is trying to load something with your script (with an Ajax request) that is on another domain (or subdomain). To avoid it (if it is on your own website) you can:

• Copy the element on your own server (but it will be static).
• You can change your HTTP header to accept Cross-Origin content. See the Access-Control-Allow-Origin documentation for more information.

I think it is because % has often be associated with the modulus operator in many programming languages.

It is the case, e.g., in C, C++, C# and Java, and many other languages which derive their syntax from C (C itself took it from B).

It is a function expression, it stands for Immediately Invoked Function Expression (IIFE). IIFE is simply a function that is executed right after it is created. So insted of the function having to wait until it is called to be executed, IIFE is executed immediately. Let's construct the IIFE by example. Suppose we have an add function which takes two integers as args and returns the sum lets make the add function into an IIFE,

Step 1: Define the function

function add (a, b){
    return a+b;
}
add(5,5);

Step2: Call the function by wrap the entire functtion declaration into parentheses

(function add (a, b){
    return a+b;
})
//add(5,5);

Step 3: To invock the function immediatly just remove the 'add' text from the call.

(function add (a, b){
    return a+b;
})(5,5);

The main reason to use an IFFE is to preserve a private scope within your function. Inside your javascript code you want to make sure that, you are not overriding any global variable. Sometimes you may accidentaly define a variable that overrides a global variable. Let's try by example. suppose we have an html file called iffe.html and codes inside body tag are-

<body>
    <div id = 'demo'></div>
    <script>
        document.getElementById("demo").innerHTML = "Hello JavaScript!";
    </script> 
</body>

Well, above code will execute with out any question, now assume you decleard a variable named document accidentaly or intentional.

<body>
    <div id = 'demo'></div>
    <script>
        document.getElementById("demo").innerHTML = "Hello JavaScript!";
        const document = "hi there";
        console.log(document);
    </script> 
</body>

you will endup in a SyntaxError: redeclaration of non-configurable global property document.

But if your desire is to declear a variable name documet you can do it by using IFFE.

<body>
    <div id = 'demo'></div>
    <script>
        (function(){
            const document = "hi there";
            this.document.getElementById("demo").innerHTML = "Hello JavaScript!";
            console.log(document);
        })();
        document.getElementById("demo").innerHTML = "Hello JavaScript!";
    </script> 
</body>

Output:

Let's try by an another example, suppose we have an calculator object like bellow-

<body>
    <script>
        var calculator = {
            add:function(a,b){
                return a+b;
            },
            mul:function(a,b){
                return a*b;
            }
        }
        console.log(calculator.add(5,10));
    </script> 
</body>

Well it's working like a charm, what if we accidently re-assigne the value of calculator object.

<body>
    <script>
        var calculator = {
            add:function(a,b){
                return a+b;
            },
            mul:function(a,b){
                return a*b;
            }
        }
        console.log(calculator.add(5,10));
        calculator = "scientific calculator";
        console.log(calculator.mul(5,5));
    </script> 
</body>

yes you will endup with a TypeError: calculator.mul is not a function iffe.html

But with the help of IFFE we can create a private scope where we can create another variable name calculator and use it;

<body>
    <script>
        var calculator = {
            add:function(a,b){
                return a+b;
            },
            mul:function(a,b){
                return a*b;
            }
        }
        var cal = (function(){
            var calculator = {
                sub:function(a,b){
                    return a-b;
                },
                div:function(a,b){
                    return a/b;
                }
            }
            console.log(this.calculator.mul(5,10));
            console.log(calculator.sub(10,5));
            return calculator;
        })();
        console.log(calculator.add(5,10));
        console.log(cal.div(10,5));
    </script> 
</body>

Output:

Thanks Nicholas Carey. I was going to use regex first but what you wrote changed my mind. It is so much easier to maintain this way.

//You can set these from your custom service methods
int minLen = 8;
int minDigit 2;
int minSpChar 2;

Boolean ErrorFlag = false;
//Check for password length
if (model.NewPassword.Length < minLen)
{
    ErrorFlag = true;
    ModelState.AddModelError("NewPassword", "Password must be at least " + minLen + " characters long.");
}

//Check for Digits and Special Characters
int digitCount = 0;
int splCharCount = 0;
foreach (char c in model.NewPassword)
{
    if (char.IsDigit(c)) digitCount++;
    if (Regex.IsMatch(c.ToString(), @"[!#$%&'()*+,-.:;<=>?@[\\\]{}^_`|~]")) splCharCount++;
}

if (digitCount < minDigit)
{
    ErrorFlag = true;
    ModelState.AddModelError("NewPassword", "Password must have at least " + minDigit + " digit(s).");
}
if (splCharCount < minSpChar)
{
    ErrorFlag = true;
    ModelState.AddModelError("NewPassword", "Password must have at least " + minSpChar + " special character(s).");
}

if (ErrorFlag)
    return View(model);

Depending on how you style the dt and dd elements, you might encounter a problem: making them have the same height. For instance, if you want to but some visible border at the bottom of those elements, you most probably want to display the border at the same height, like in a table.

One solution for this is cheating and make each row a "dl" element. (this is equivalent to using tr in a table) We loose the original interest of definition lists, but on the counterpart this is an easy manner to get pseudo-tables that are quickly and pretty styled.

THE CSS:

dl {
 margin:0;
 padding:0;
 clear:both;
 overflow:hidden;
}
dt {
 margin:0;
 padding:0;
 float:left;
 width:28%;
 list-style-type:bullet;
}
dd {
 margin:0;
 padding:0;
 float:right;
 width:72%;
}

.huitCinqPts dl dt, .huitCinqPts dl dd {font-size:11.3px;}
.bord_inf_gc dl {padding-top:0.23em;padding-bottom:0.5em;border-bottom:1px solid #aaa;}

THE HTML:

<div class="huitCinqPts bord_inf_gc">
  <dl><dt>Term1</dt><dd>Definition1</dd></dl>
  <dl><dt>Term2</dt><dd>Definition2</dd></dl>
</div>

If you don't have DBA rights then you can use user_segments table:

select bytes/1024/1024 MB from user_segments where segment_name='Table_name'

For Registry Key you can check if it is null after getting it. It will be, if it doesn't exist.

For Registry Value you can get names of Values for the current key and check if this array contains the needed Value name.

Example:

public static bool checkMachineType()
{    
    RegistryKey winLogonKey = Registry.LocalMachine.OpenSubKey(@"System\CurrentControlSet\services\pcmcia", true);
    return (winLogonKey.GetValueNames().Contains("Start"));
}

On Windows 10 and Android Studio you can go in Android Studio to "File"->"Settings" in Settings then to "Appearance & Behavior" -> "System Settings" -> "Android SDK". In the Tab "SDK Tools" active:

• "Android SDK Build-Tools .."
• "Android Emulator"
• "Android SDK Plattform-Tools"
• "Android SDK Tools"

If all installed then you can start the Emulator in Android Studio with "Tools" -> "Android" -> "AVD Manager". If the Emulator run you can try "react-native run-android"

The guid provided is not correct format(.net Provided guid).

This now works for IE FF Chrome properly... I have not tested for other browsers though

$(document).ready(function(){
   $('#txtInput').on("cut copy paste",function(e) {
      e.preventDefault();
   });
});

Edit: As pointed out by webeno, .bind() is deprecated hence it is recommended to use .on() instead.

In above code, you don't pass the kml data to your mapView anywhere in your code, as far as I can see. To display the route, you should parse the kml data i.e. via SAX parser, then display the route markers on the map.

See the code below for an example, but it's not complete though - just for you as a reference and get some idea.

This is a simple bean I use to hold the route information I will be parsing.

package com.myapp.android.model.navigation;

import java.util.ArrayList;
import java.util.Iterator;


public class NavigationDataSet { 

private ArrayList<Placemark> placemarks = new ArrayList<Placemark>();
private Placemark currentPlacemark;
private Placemark routePlacemark;

public String toString() {
    String s= "";
    for (Iterator<Placemark> iter=placemarks.iterator();iter.hasNext();) {
        Placemark p = (Placemark)iter.next();
        s += p.getTitle() + "\n" + p.getDescription() + "\n\n";
    }
    return s;
}

public void addCurrentPlacemark() {
    placemarks.add(currentPlacemark);
}

public ArrayList<Placemark> getPlacemarks() {
    return placemarks;
}

public void setPlacemarks(ArrayList<Placemark> placemarks) {
    this.placemarks = placemarks;
}

public Placemark getCurrentPlacemark() {
    return currentPlacemark;
}

public void setCurrentPlacemark(Placemark currentPlacemark) {
    this.currentPlacemark = currentPlacemark;
}

public Placemark getRoutePlacemark() {
    return routePlacemark;
}

public void setRoutePlacemark(Placemark routePlacemark) {
    this.routePlacemark = routePlacemark;
}

}

And the SAX Handler to parse the kml:

package com.myapp.android.model.navigation;

import android.util.Log;
import com.myapp.android.myapp;
import org.xml.sax.Attributes;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;

          this.in_coordinatestag = true;                        
      }
 } 

 /** Gets be called on closing tags like:

 @Override

       if ("Route".equals(navigationDataSet.getCurrentPlacemark().getTitle())) 
               navigationDataSet.setRoutePlacemark(navigationDataSet.getCurrentPlacemark());
        else navigationDataSet.addCurrentPlacemark();

           this.in_coordinatestag = false;
       }
 } 

 /** Gets be called on the following structure:

 @Override 
public void characters(char ch[], int start, int length) { 
    if(this.in_nametag){

        navigationDataSet.getCurrentPlacemark().setTitle(new String(ch, start, length));

        //navigationDataSet.getCurrentPlacemark().setCoordinates(new String(ch, start, length));
        buffer.append(ch, start, length);
    }
} 
}

and a simple placeMark bean:

package com.myapp.android.model.navigation;

public class Placemark {

String title;
String description;
String coordinates;
String address;

public String getTitle() {
    return title;
}
public void setTitle(String title) {
    this.title = title;
}
public String getDescription() {
    return description;
}
public void setDescription(String description) {
    this.description = description;
}
public String getCoordinates() {
    return coordinates;
}
public void setCoordinates(String coordinates) {
    this.coordinates = coordinates;
}
public String getAddress() {
    return address;
}
public void setAddress(String address) {
    this.address = address;
}

}

Finally the service class in my model that calls the calculation:

This is quote from the book "Programming in Go: Creating Applications for the 21st Century":

Using a simple linear search like this is the only option for unsorted data and is fine for small slices (up to hundreds of items). But for larger slices—especially if we are performing searches repeatedly—the linear search is very inefficient, on average requiring half the items to be compared each time.

Go provides a sort.Search() method which uses the binary search algorithm: This requires the comparison of only log2(n) items (where n is the number of items) each time. To put this in perspective, a linear search of 1000000 items requires 500000 comparisons on average, with a worst case of 1000000 comparisons; a binary search needs at most 20 comparisons, even in the worst case.

files := []string{"Test.conf", "util.go", "Makefile", "misc.go", "main.go"}
target := "Makefile"
sort.Strings(files)
i := sort.Search(len(files),
    func(i int) bool { return files[i] >= target })
if i < len(files) && files[i] == target {
    fmt.Printf("found \"%s\" at files[%d]\n", files[i], i)
}

Resolved this problem using a Sequence ID defined in Oracle database.

ORACLE_DB_SEQ_ID is defined as a sequence for the table. Also look at the console to see the Hibernate SQL that is used to verify.

@Id
@Column(name = "MY_ID", unique = true, nullable = false)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator = "id_Sequence")
@SequenceGenerator(name = "id_Sequence", sequenceName = "ORACLE_DB_SEQ_ID")
Long myId;

Many times the bolded text is regarded in an information architecture way on another level and thus not have bolded and regular in one line, so you can split it to two labels/textViews, one regular and on bold italic. And use the editor to choose the font styles.

You're nearly there, just take out the EXECUTE:

DECLARE
  procId NUMBER;

BEGIN
  PKG1.INIT(1143824, 0, procId);
  DBMS_OUTPUT.PUT_LINE(procId);
END;

Excerpt from the Java API for addAll(collection c) in Interface List see here

"Appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection's iterator (optional operation)."

You you will have as much object as you have in both lists - the number of objects in your first list plus the number of objects you have in your second list - in your case 100.

If you're not using gradle (creating a project from an APK, for instance), this can be done through the Android Studio UI (as of version 3.3.2):

• Right-click the project root directory, pick Open Module Settings
• Hit the + Add Content Root button (center right)
• Add your path and hit OK

In my experience (with native code), as long as your .so's are built with debug symbols and from the same absolute paths, breakpoints added in source files will be automatically recognized.

Here is another way that you want.

$(document).ready(function(){   
    $('#checkp').toggle(
        function () { 
            $('.check').attr('Checked','Checked'); 
        },
        function () { 
            $('.check').removeAttr('Checked'); 
        }
    );
});

Time package in Golang has some methods that might be worth looking.

func (Time) Format

func (t Time) Format(layout string) string Format returns a textual representation of the time value formatted according to layout, which defines the format by showing how the reference time,

Mon Jan 2 15:04:05 -0700 MST 2006 would be displayed if it were the value; it serves as an example of the desired output. The same display rules will then be applied to the time value. Predefined layouts ANSIC, UnixDate, RFC3339 and others describe standard and convenient representations of the reference time. For more information about the formats and the definition of the reference time, see the documentation for ANSIC and the other constants defined by this package.

Source (http://golang.org/pkg/time/#Time.Format)

I also found an example of defining the layout (http://golang.org/src/pkg/time/example_test.go)

func ExampleTime_Format() {
        // layout shows by example how the reference time should be represented.
        const layout = "Jan 2, 2006 at 3:04pm (MST)"
        t := time.Date(2009, time.November, 10, 15, 0, 0, 0, time.Local)
        fmt.Println(t.Format(layout))
        fmt.Println(t.UTC().Format(layout))
        // Output:
    // Nov 10, 2009 at 3:00pm (PST)
        // Nov 10, 2009 at 11:00pm (UTC)
    }

Theres two properties on the model you need to set. The first $primaryKey to tell the model what column to expect the primary key on. The second $incrementing so it knows the primary key isn't a linear auto incrementing value.

class MyModel extends Model
{
    protected $primaryKey = 'my_column';

    public $incrementing = false;
}

For more info see the Primary Keys section in the documentation on Eloquent.

Throw it away when Bootstrap comes with a fix for this problem.

The short answer:

Use the click event, which won't fire until after the value has been updated, and fires when you want it to:

<label><input type='checkbox' onclick='handleClick(this);'>Checkbox</label>

function handleClick(cb) {
  display("Clicked, new value = " + cb.checked);
}

Live example | Source

The longer answer:

The change event handler isn't called until the checked state has been updated (live example | source), but because (as Tim Büthe points out in the comments) IE doesn't fire the change event until the checkbox loses focus, you don't get the notification proactively. Worse, with IE if you click a label for the checkbox (rather than the checkbox itself) to update it, you can get the impression that you're getting the old value (try it with IE here by clicking the label: live example | source). This is because if the checkbox has focus, clicking the label takes the focus away from it, firing the change event with the old value, and then the click happens setting the new value and setting focus back on the checkbox. Very confusing.

But you can avoid all of that unpleasantness if you use click instead.

I've used DOM0 handlers (onxyz attributes) because that's what you asked about, but for the record, I would generally recommend hooking up handlers in code (DOM2's addEventListener, or attachEvent in older versions of IE) rather than using onxyz attributes. That lets you attach multiple handlers to the same element and lets you avoid making all of your handlers global functions.

An earlier version of this answer used this code for handleClick:

function handleClick(cb) {
  setTimeout(function() {
    display("Clicked, new value = " + cb.checked);
  }, 0);
}

The goal seemed to be to allow the click to complete before looking at the value. As far as I'm aware, there's no reason to do that, and I have no idea why I did. The value is changed before the click handler is called. In fact, the spec is quite clear about that. The version without setTimeout works perfectly well in every browser I've tried (even IE6). I can only assume I was thinking about some other platform where the change isn't done until after the event. In any case, no reason to do that with HTML checkboxes.

Either structure is valid and accessible, but the for attribute should be equal to the id of the input element:

<input type="radio" ... id="r1" /><label for="r1">button text</label>

or

<label for="r1"><input type="radio" ... id="r1" />button text</label>

The for attribute is optional in the second version (label containing input), but IIRC there were some older browsers that didn't make the label text clickable unless you included it. The first version (label after input) is easier to style with CSS using the adjacent sibling selector +:

input[type="radio"]:checked+label {font-weight:bold;}

These are few things which will help you in understanding everything... using iloc

In iloc, [initial row:ending row, initial column:ending column]

case 1: if you want only last column --- df.iloc[:,-1] & df.iloc[:,-1:] this means that you want only the last column...

case 2: if you want all columns and all rows except the last column --- df.iloc[:,:-1] this means that you want all columns and all rows except the last column...

case 3: if you want only last row --- df.iloc[-1:,:] & df.iloc[-1,:] this means that you want only the last row...

case 4: if you want all columns and all rows except the last row --- df.iloc[:-1,:] this means that you want all columns and all rows except the last column...

case 5: if you want all columns and all rows except the last row and last column --- df.iloc[:-1,:-1] this means that you want all columns and all rows except the last column and last row...

Add the "collapse" class to the alert div and the alert will be "collapsed" (hidden) by default. You can still call it using "show"

<div class="alert alert-error collapse" role="alert" id="passwordsNoMatchRegister">
  <span>
  <p>Looks like the passwords you entered don't match!</p>
  </span>
</div>

In the GSM specification 3GPP TS 11.11, there are 10 bytes set aside in the MSISDN EF (6F40) for 'dialing number'. Since this is the GSM representation of a phone number, and it's usage is nibble swapped, (and there is always the possibility of parentheses) 22 characters of data should be plenty.

In my experience, there is only one instance of open/close parentheses, that is my reasoning for the above.

The default is: decimal(18,0)

When you set targetSdkVersion="xx", you are certifying that your app works properly (e.g., has been thoroughly and successfully tested) at API level xx.

A version of Android running at an API level above xx will apply compatibility code automatically to support any features you might be relying upon that were available at or prior to API level xx, but which are now obsolete at that Android version's higher level.

Conversely, if you are using any features that became obsolete at or prior to level xx, compatibility code will not be automatically applied by OS versions at higher API levels (that no longer include those features) to support those uses. In that situation, your own code must have special case clauses that test the API level and, if the OS level detected is a higher one that no longer has the given API feature, your code must use alternate features that are available at the running OS's API level.

If it fails to do this, then some interface features may simply not appear that would normally trigger events within your code, and you may be missing a critical interface feature that the user needs to trigger those events and to access their functionality (as in the example below).

As stated in other answers, you might set targetSdkVersion higher than minSdkVersion if you wanted to use some API features initially defined at higher API levels than your minSdkVersion, and had taken steps to ensure that your code could detect and handle the absence of those features at lower levels than targetSdkVersion.

In order to warn developers to specifically test for the minimum API level required to use a feature, the compiler will issue an error (not just a warning) if code contains a call to any method that was defined at a later API level than minSdkVersion, even if targetSdkVersion is greater than or equal to the API level at which that method was first made available. To remove this error, the compiler directive

@TargetApi(nn)

tells the compiler that the code within the scope of that directive (which will precede either a method or a class) has been written to test for an API level of at least nn prior to calling any method that depends upon having at least that API level. For example, the following code defines a method that can be called from code within an app that has a minSdkVersion of less than 11 and a targetSdkVersion of 11 or higher:

@TargetApi(11)
    public void refreshActionBarIfApi11OrHigher() {
      //If the API is 11 or higher, set up the actionBar and display it
      if(Build.VERSION.SDK_INT >= 11) {
        //ActionBar only exists at API level 11 or higher
        ActionBar actionBar = getActionBar();

        //This should cause onPrepareOptionsMenu() to be called.
        // In versions of the API prior to 11, this only occurred when the user pressed 
        // the dedicated menu button, but at level 11 and above, the action bar is 
        // typically displayed continuously and so you will need to call this
        // each time the options on your menu change.
        invalidateOptionsMenu();

        //Show the bar
        actionBar.show();
    }
}

You might also want to declare a higher targetSdkVersion if you had tested at that higher level and everything worked, even if you were not using any features from an API level higher than your minSdkVersion. This would be just to avoid the overhead of accessing compatibility code intended to adapt from the target level down to the min level, since you would have confirmed (through testing) that no such adaptation was required.

An example of a UI feature that depends upon the declared targetSdkVersion would be the three-vertical-dot menu button that appears on the status bar of apps having a targetSdkVersion less than 11, when those apps are running under API 11 and higher. If your app has a targetSdkVersion of 10 or below, it is assumed that your app's interface depends upon the existence of a dedicated menu button, and so the three-dot button appears to take the place of the earlier dedicated hardware and/or onscreen versions of that button (e.g., as seen in Gingerbread) when the OS has a higher API level for which a dedicated menu button on the device is no longer assumed. However, if you set your app's targetSdkVersion to 11 or higher, it is assumed that you have taken advantage of features introduced at that level that replace the dedicated menu button (e.g., the Action Bar), or that you have otherwise circumvented the need to have a system menu button; consequently, the three-vertical-dot menu "compatibility button" disappears. In that case, if the user can't find a menu button, she can't press it, and that, in turn, means that your activity's onCreateOptionsMenu(menu) override might never get invoked, which, again in turn, means that a significant part of your app's functionality could be deprived of its user interface. Unless, of course, you have implemented the Action Bar or some other alternative means for the user to access these features.

minSdkVersion, by contrast, states a requirement that a device's OS version have at least that API level in order to run your app. This affects which devices are able to see and download your app when it is on the Google Play app store (and possibly other app stores, as well). It's a way of stating that your app relies upon OS (API or other) features that were established at that level, and does not have an acceptable way to deal with the absence of those features.

An example of using minSdkVersion to ensure the presence of a feature that is not API-related would be to set minSdkVersion to 8 in order to ensure that your app will run only on a JIT-enabled version of the Dalvik interpreter (since JIT was introduced to the Android interpreter at API level 8). Since performance for a JIT-enabled interpreter can be as much as five times that of one lacking that feature, if your app makes heavy use of the processor then you might want to require API level 8 or above in order to ensure adequate performance.

I was getting this error when I was trying to ssh into an ec2 instance on the private subnet from the bastion, to fix this issue, you've to run (ssh-add -K) as follow.

    Step 1: run "chmod 400 myEC2Key.pem"
    Step 2: run "ssh-add -K ./myEC2Key.pem" on your local machine
    Step 3: ssh -i myEC2Key.pem [email protected]
    Step 4: Now try to ssh to EC2 instance that is on a private subnet without specifying the key, for example, try ssh ec2-user@ipaddress.

    Hope this will help.
Note: This solution is for Mac.

Use %in% as follows

A$C %in% B$C

Which will tell you which values of column C of A are in B.

What is returned is a logical vector. In the specific case of your example, you get:

A$C %in% B$C
# [1]  TRUE FALSE  TRUE  TRUE

Which you can use as an index to the rows of A or as an index to A$C to get the actual values:

# as a row index
A[A$C %in% B$C,  ]  # note the comma to indicate we are indexing rows

# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4  # returns all values of A$C that are in B$C

We can negate it too:

A$C[!A$C %in% B$C]
[1] 2   # returns all values of A$C that are NOT in B$C

  2 %in% B$C   # "is the value 2 in B$C ?"  
  # FALSE

  A$C[2] %in% B$C  # "is the 2nd element of A$C in B$C ?"  
  # FALSE

*data interprets arguments as tuples, instead you have to pass **data which interprets the arguments as dictionary.

data = {'school':'DAV', 'class': '7', 'name': 'abc', 'city': 'pune'}


def my_function(**data):
    schoolname  = data['school']
    cityname = data['city']
    standard = data['class']
    studentname = data['name']

You can call the function like this:

my_function(**data)

You can bind with a variable in the controller:

<input type="text" ng-model="inputText" placeholder="{{somePlaceholder}}" />

In the controller:

$scope.somePlaceholder = 'abc';

//Parent/Children[@  Attribute='value']/@Attribute

This is the case which can be used where element is having 2 attribute and we can get the one attribute with the help of another one.

You can do that by applying your rotate CSS to an inner element and then adjusting the height of the element to match its width since the element was rotated to fit it into the <td>.

Also make sure you change your id #rotate to a class since you have multiple.

  $('.rotate').css('height', $('.rotate').width());_x000D_

jsFiddle

window.addEventListener('load', function () {
    var rotates = document.getElementsByClassName('rotate');
    for (var i = 0; i < rotates.length; i++) {
        rotates[i].style.height = rotates[i].offsetWidth + 'px';
    }
});

5 years have passed and this essential requirement didn't get ignored by the Chrome devs.
While they offer no method to edit the data like in Firefox, they offer a full XHR replay.
This allows to debug ajax calls.

"Replay XHR" will repeat the entire transmission.

I have a simple bash script I created for this it just means running it on your file before use: https://github.com/antonosmond/subber

Basically just create your compose file using double curly braces to denote environment variables e.g:

app:
    build: "{{APP_PATH}}"
ports:
    - "{{APP_PORT_MAP}}"

Anything in double curly braces will be replaced with the environment variable of the same name so if I had the following environment variables set:

APP_PATH=~/my_app/build
APP_PORT_MAP=5000:5000

on running subber docker-compose.yml the resulting file would look like:

app:
    build: "~/my_app/build"
ports:
    - "5000:5000"

Little sum up for searching by row:

This can be useful if you don't know the column values ??or if columns have non-numeric values

if u want get index number as integer u can also do:

item = df[4:5].index.item()
print(item)
4

it also works in numpy / list:

numpy = df[4:7].index.to_numpy()[0]
lista = df[4:7].index.to_list()[0]

in [x] u pick number in range [4:7], for example if u want 6:

numpy = df[4:7].index.to_numpy()[2]
print(numpy)
6

for DataFrame:

df[4:7]

    A          B
4   5   0.894525
5   6   0.978174
6   7   0.859449

or:

df[(df.index>=4) & (df.index<7)]

    A          B
4   5   0.894525
5   6   0.978174
6   7   0.859449   

=== What about future proofing and code reuse? ===

If you don't write the code to free the objects, then you are limiting the code to only being safe to use when you can depend on the memory being free'd by the process being closed ... i.e. small one-time use projects or "throw-away"^[1] projects)... where you know when the process will end.

If you do write the code that free()s all your dynamically allocated memory, then you are future proofing the code and letting others use it in a larger project.

^{[1] regarding "throw-away" projects. Code used in "Throw-away" projects has a way of not being thrown away. Next thing you know ten years have passed and your "throw-away" code is still being used).}

^{I heard a story about some guy who wrote some code just for fun to make his hardware work better. He said "just a hobby, won't be big and professional". Years later lots of people are using his "hobby" code.}

I wanted to do this so wrote a simple function. It works great for me and is quite versatile (supports years to microseconds, and any granularity level, e.g. you can pick between '2 days, 4 hours, 48 minutes' and '2 days, 4 hours' and '2 days, 4.8 hours', etc.

def pretty_print_timedelta(t, max_components=None, max_decimal_places=2):

For example datetime.timedelta(days=2, seconds=17280) will be printed as '2 days, 4 hours, 48 minutes'. Setting max_components to e.g. 1 will change this to '2.2 days', where the 
number of decimal points can also be set.

time_scales = [timedelta(days=365), timedelta(days=1), timedelta(hours=1), timedelta(minutes=1), timedelta(seconds=1), timedelta(microseconds=1000), timedelta(microseconds=1)]

Another option in case you don't wanna use a plugin:

Ctrl+` or

View -> Show Console

type on the console the following command:

view.encoding()

In case you want to something more intrusive, there's a option to create an shortcut that executes the following command:

sublime.message_dialog(view.encoding())

The reason reset and revert tend to come up a lot in the same conversations is because different version control systems use them to mean different things.

In particular, people who are used to SVN or P4 who want to throw away uncommitted changes to a file will often reach for revert before being told that they actually want reset.

Similarly, the revert equivalent in other VCSes is often called rollback or something similar - but "rollback" can also mean "I want to completely discard the last few commits", which is appropriate for reset but not revert. So, there's a lot of confusion where people know what they want to do, but aren't clear on which command they should be using for it.

As for your actual questions about revert...

Okay, you're going to use git revert but how?

git revert first-bad-commit..last-bad-commit

And after running git revert do you have to do something else after? Do you have to commit the changes revert made or does revert directly commit to the repo or what??

By default, git revert prompts you for a commit message and then commits the results. This can be overridden. I quote the man page:

--edit

With this option, git revert will let you edit the commit message prior to committing the revert. This is the default if you run the command from a terminal.

--no-commit

Usually the command automatically creates some commits with commit log messages stating which commits were reverted. This flag applies the changes necessary to revert the named commits to your working tree and the index, but does not make the commits. In addition, when this option is used, your index does not have to match the HEAD commit. The revert is done against the beginning state of your index.

This is useful when reverting more than one commits' effect to your index in a row.

In particular, by default it creates a new commit for each commit you're reverting. You can use revert --no-commit to create changes reverting all of them without committing those changes as individual commits, then commit at your leisure.

You can catch form input values using FormData and send them by fetch

fetch(form.action,{method:'post', body: new FormData(form)});

function send(e,form) {_x000D_
  fetch(form.action,{method:'post', body: new FormData(form)});_x000D_
_x000D_
  console.log('We send post asynchronously (AJAX)');_x000D_
  e.preventDefault();_x000D_
}

As you are referring to a combobox, I'm assuming you don't want to use 2-way databinding (if so, look at using a BindingList)

public class Country
{
    public string Name { get; set; }
    public IList<City> Cities { get; set; }
    public Country(string _name)
    {
        Cities = new List<City>();
        Name = _name;
    }
}

List<Country> countries = new List<Country> { new Country("UK"), 
                                     new Country("Australia"), 
                                     new Country("France") };

var bindingSource1 = new BindingSource();
bindingSource1.DataSource = countries;

comboBox1.DataSource = bindingSource1.DataSource;

comboBox1.DisplayMember = "Name";
comboBox1.ValueMember = "Name";

To find the country selected in the bound combobox, you would do something like: Country country = (Country)comboBox1.SelectedItem;.

If you want the ComboBox to dynamically update you'll need to make sure that the data structure that you have set as the DataSource implements IBindingList; one such structure is BindingList<T>.

Tip: make sure that you are binding the DisplayMember to a Property on the class and not a public field. If you class uses public string Name { get; set; } it will work but if it uses public string Name; it will not be able to access the value and instead will display the object type for each line in the combo box.

Here's the link that gives me the answer:

[Install] the "fake sendmail for windows". If you are not using XAMPP you can download it here: http://glob.com.au/sendmail/sendmail.zip

[Modify] the php.ini file to use it (commented out the other lines):

[mail function]
; For Win32 only.
; SMTP = smtp.gmail.com
; smtp_port = 25

; For Win32 only.
; sendmail_from = <e-mail username>@gmail.com

; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(ignore the "Unix only" bit, since we actually are using sendmail)

You then have to configure the "sendmail.ini" file in the directory where sendmail was installed:

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=25
error_logfile=error.log
debug_logfile=debug.log
auth_username=<username>
auth_password=<password>
force_sender=<e-mail username>@gmail.com

To access a Gmail account protected by 2-factor verification, you will need to create an application-specific password. (source)

I like the definition from Brian Goetz's Java Concurrency in Practice for its comprehensiveness

"A class is thread-safe if it behaves correctly when accessed from multiple threads, regardless of the scheduling or interleaving of the execution of those threads by the runtime environment, and with no additional synchronization or other coordination on the part of the calling code."

You did everything except copying the new pixel value back to the image.

This line takes a copy of the pixel into a local variable:

Vec3b color = image.at<Vec3b>(Point(x,y));

So, after changing color as you require, just set it back like this:

image.at<Vec3b>(Point(x,y)) = color;

So, in full, something like this:

Mat image = img;
for(int y=0;y<img.rows;y++)
{
    for(int x=0;x<img.cols;x++)
    {
        // get pixel
        Vec3b & color = image.at<Vec3b>(y,x);

        // ... do something to the color ....
        color[0] = 13;
        color[1] = 13;
        color[2] = 13;

        // set pixel
        //image.at<Vec3b>(Point(x,y)) = color;
        //if you copy value
    }
}

I use the npm clone library. Apparently it also works in the browser.

https://www.npmjs.com/package/clone

let a = clone(b)

Just remove the event before adding it :

document.getElementById('link2').removeEventListener('click', linkclick, false);
document.getElementById('link2').addEventListener('click', linkclick, false);

Just initialize an array and push the element on the array. It will automatic scale the array.

var a = [ ];

a.push('Some string'); console.log(a); // ['Some string'] 
a.push('another string'); console.log(a); // ['Some string', 'another string'] 
a.push('Some string'); console.log(a); // ['Some string', 'another string', 'Some string']

The tag set depends on the corpus that was used to train the tagger. The default tagger of nltk.pos_tag() uses the Penn Treebank Tag Set.

In NLTK 2, you could check which tagger is the default tagger as follows:

import nltk
nltk.tag._POS_TAGGER
>>> 'taggers/maxent_treebank_pos_tagger/english.pickle'

That means that it's a Maximum Entropy tagger trained on the Treebank corpus.

nltk.tag._POS_TAGGER does not exist anymore in NLTK 3 but the documentation states that the off-the-shelf tagger still uses the Penn Treebank tagset.

As you can see in the documentation of JSHint you can change options per function or per file. In your case just place a comment in your file or even more local just in the function that uses eval:

/*jshint evil:true */

function helloEval(str) {
    /*jshint evil:true */
    eval(str);
}

You can use the relationLoaded method on the model object. This saved my bacon so hopefully it helps someone else. I was given this suggestion when I asked the same question on Laracasts.

In your screenshot, you didn't specify any module: try setting "libsystem_c.dylib"

I did that, and it works : breakpoint stops here (although the stacktrace often rise from some obscure system lib...)

You can't. Variables defined inside a method are local to that method.

If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).

Looks like you're using instance methods instead of static ones.

If you don't want to create an object, you should declare all your methods static, so something like

private static void methodName(Argument args...)

If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.

private static int[][] array = new int[3][5];

Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.

Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.

Here's a final (shortened) example of what your code should be like:

public class Test3 {
    //Use this array in your methods
    private static int[][] scores = new int[3][5];

    /* Rather than just "Scores" name it so people know what
     * to expect
     */
    private static void createScores() {
        //Code...
    }
    //Other methods...

    /* Since you're now using static methods, you don't 
     * have to initialise an object and call its methods.
     */
    public static void main(String[] args){
        createScores();
        MD();   //Don't know what these do
        sumD(); //so I'll leave them.
    }
}

Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.

Very simple use:

function current_url() {
    $current_url  = ( $_SERVER["HTTPS"] != 'on' ) ? 'http://'.$_SERVER["SERVER_NAME"] :  'https://'.$_SERVER["SERVER_NAME"];
    $current_url .= ( $_SERVER["SERVER_PORT"] != 80 ) ? ":".$_SERVER["SERVER_PORT"] : "";
    $current_url .= $_SERVER["REQUEST_URI"];

    return $current_url;
}

You can download in the current directory with a . :

cd # by default, goes to $HOME
scp me@host:/path/to/file .

or in you HOME directly with :

scp me@host:/path/to/file ~

My preferred way is this. It handles the escaping and parsing for you.

WebClient webClient = new WebClient();
webClient.QueryString.Add("param1", "value1");
webClient.QueryString.Add("param2", "value2");
string result = webClient.DownloadString("http://theurl.com");

I went through this when trying to get a clientcert and private key out of a keystore.

The link above posted by welsh was great, but there was an extra step on my redhat distribution. If curl is built with NSS ( run curl --version to see if you see NSS listed) then you need to import the keys into an NSS keystore. I went through a bunch of convoluted steps, so this may not be the cleanest way, but it got things working

So export the keys into .p12

keytool -importkeystore -srckeystore $jksfile -destkeystore $p12file \
        -srcstoretype JKS -deststoretype PKCS12 \
        -srcstorepass $jkspassword -deststorepass $p12password  
        -srcalias $myalias -destalias $myalias \
        -srckeypass $keypass -destkeypass $keypass -noprompt

And generate the pem file that holds only the key

 echo making ${fileroot}.key.pem
 openssl pkcs12 -in $p12 -out ${fileroot}.key.pem  \
         -passin pass:$p12password  \
         -passout pass:$p12password  -nocerts

• Make an empty keystore:

mkdir ~/nss
chmod 700 ~/nss
certutil -N -d ~/nss

• Import the keys into the keystore

pks12util -i <mykeys>.p12 -d ~/nss -W <password for cert >

Now curl should work.

curl --insecure --cert <client cert alias>:<password for cert> \
     --key ${fileroot}.key.pem  <URL>

As I mentioned, there may be other ways to do this, but at least this was repeatable for me. If curl is compiled with NSS support, I was not able to get it to pull the client cert from a file.

If anyone is looking out for using it to apply on the react then you can follow the code pattern given below. You have to add extra property which is rel.

Eclipse is a runtime environment for plugins. Virtually everything you see in Eclipse is the result of plugins installed on Eclipse, rather than Eclipse itself.

The .project file is maintained by the core Eclipse platform, and its goal is to describe the project from a generic, plugin-independent Eclipse view. What's the project's name? what other projects in the workspace does it refer to? What are the builders that are used in order to build the project? (remember, the concept of "build" doesn't pertain specifically to Java projects, but also to other types of projects)

The .classpath file is maintained by Eclipse's JDT feature (feature = set of plugins). JDT holds multiple such "meta" files in the project (see the .settings directory inside the project); the .classpath file is just one of them. Specifically, the .classpath file contains information that the JDT feature needs in order to properly compile the project: the project's source folders (that is, what to compile); the output folders (where to compile to); and classpath entries (such as other projects in the workspace, arbitrary JAR files on the file system, and so forth).

Blindly copying such files from one machine to another may be risky. For example, if arbitrary JAR files are placed on the classpath (that is, JAR files that are located outside the workspace and are referred-to by absolute path naming), the .classpath file is rendered non-portable and must be modified in order to be portable. There are certain best practices that can be followed to guarantee .classpath file portability.

Define versionName in AndroidManifest.xml

android:versionName="5.1.5"

Inside android{...} block in build.gradle of app level :

defaultConfig {
        applicationId "com.example.autoincrement"
        minSdkVersion 18
        targetSdkVersion 23
        multiDexEnabled true
        def version = getIncrementationVersionName()
        versionName version
}

Outside android{...} block in build.gradle of app level :

def getIncrementedVersionName() {
    List<String> runTasks = gradle.startParameter.getTaskNames();

    //find version name in manifest
    def manifestFile = file('src/main/AndroidManifest.xml')
    def matcher = Pattern.compile('versionName=\"(\\d+)\\.(\\d+)\\.(\\d+)\"').matcher(manifestFile.getText())
    matcher.find()

    //extract versionName parts
    def firstPart = Integer.parseInt(matcher.group(1))
    def secondPart = Integer.parseInt(matcher.group(2))
    def thirdPart = Integer.parseInt(matcher.group(3))

    //check is runTask release or not
    // if release - increment version
    for (String item : runTasks) {
        if (item.contains("assemble") && item.contains("Release")) {
            thirdPart++
            if (thirdPart == 10) {
                thirdPart = 0;
                secondPart++
                if (secondPart == 10) {
                    secondPart = 0;
                    firstPart++
                }
            }
        }
    }

    def versionName = firstPart + "." + secondPart + "." + thirdPart

    // update manifest
    def manifestContent = matcher.replaceAll('versionName=\"' + versionName + '\"')
    manifestFile.write(manifestContent)

    println "incrementVersionName = " + versionName

    return versionName
}

After create singed APK :

android:versionName="5.1.6"

Note : If your versionName different from my, you need change regex and extract parts logic.

The easiest way is to use toolbarHeight property in your AppBar

Example :

AppBar(
   title: Text('Flutter is great'),
   toolbarHeight: 100,
  ),

You can add flexibleSpace property in your appBar for more flexibility

Output:

For more controls , Use the PreferedSize widget to create your own appBar

Example :

appBar: PreferredSize(
     preferredSize: Size(100, 80), //width and height 
          // The size the AppBar would prefer if there were no other constraints.
     child: SafeArea(
       child: Container(
         height: 100,
         color: Colors.red,
         child: Center(child: Text('Fluter is great')),
       ),
     ),
),

Don't forget to use a SafeArea widget if you don't have a safeArea

Output :

Had similar error with the same result with Gradle and was able to solve it by following:

//compile 'org.slf4j:slf4j-api:1.7.1'
compile group: 'org.apache.logging.log4j', name: 'log4j-api', version: '2.1'
compile group: 'org.apache.logging.log4j', name: 'log4j-core', version: '2.1'
compile group: 'org.apache.logging.log4j', name: 'log4j-slf4j-impl', version: '2.1'

Out-commented line is the one which caused the error output. I believe you can transfer this to Maven.

Well, to answer the immediate question:

>>> s = "http://www.domain.com/?s=some&two=20"

The rfind method returns the index of right-most substring:

>>> s.rfind("&")
29

You can take all elements up to a given index with the slicing operator:

>>> "foobar"[:4]
'foob'

Putting the two together:

>>> s[:s.rfind("&")]
'http://www.domain.com/?s=some'

If you are dealing with URLs in particular, you might want to use built-in libraries that deal with URLs. If, for example, you wanted to remove two from the above query string:

First, parse the URL as a whole:

>>> import urlparse, urllib
>>> parse_result = urlparse.urlsplit("http://www.domain.com/?s=some&two=20")
>>> parse_result
SplitResult(scheme='http', netloc='www.domain.com', path='/', query='s=some&two=20', fragment='')

Take out just the query string:

>>> query_s = parse_result.query
>>> query_s
's=some&two=20'

Turn it into a dict:

>>> query_d = urlparse.parse_qs(parse_result.query)
>>> query_d
{'s': ['some'], 'two': ['20']}
>>> query_d['s']
['some']
>>> query_d['two']
['20']

Remove the 'two' key from the dict:

>>> del query_d['two']
>>> query_d
{'s': ['some']}

Put it back into a query string:

>>> new_query_s = urllib.urlencode(query_d, True)
>>> new_query_s
's=some'

And now stitch the URL back together:

>>> result = urlparse.urlunsplit((
    parse_result.scheme, parse_result.netloc,
    parse_result.path, new_query_s, parse_result.fragment))
>>> result
'http://www.domain.com/?s=some'

The benefit of this is that you have more control over the URL. Like, if you always wanted to remove the two argument, even if it was put earlier in the query string ("two=20&s=some"), this would still do the right thing. It might be overkill depending on what you want to do.

Steps to manually configure DNS:

1. You can access Network and Sharing center by right clicking on the Network icon on the taskbar.

2. Now choose adapter settings from the side menu.

3. This will give you a list of the available network adapters in the system . From them right click on the adapter you are using to connect to the internet now and choose properties option.

4. In the networking tab choose ‘Internet Protocol Version 4 (TCP/IPv4)’.

5. Now you can see the properties dialogue box showing the properties of IPV4. Here you need to change some properties.

   Select ‘use the following DNS address’ option. Now fill the following fields as given here.

   Preferred DNS server: 208.67.222.222

   Alternate DNS server : 208.67.220.220

   This is an available Open DNS address. You may also use google DNS server addresses.

   After filling these fields. Check the ‘validate settings upon exit’ option. Now click OK.

You have to add this DNS server address in the router configuration also (by referring the router manual for more information).

Refer : for above method & alternative

If none of this works, then open command prompt(Run as Administrator) and run these:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
NETSH winsock reset catalog
NETSH int ipv4 reset reset.log
NETSH int ipv6 reset reset.log
Exit

Hopefully that fixes it, if its still not fixed there is a chance that its a NIC related issue(driver update or h/w).

Also FYI, this has a thread on Microsoft community : Windows 10 - DNS Issue

The simplest solution is to select the second cell, and press =. This will begin the fomula creation process. Now either type in the 1st cell reference (eg, A1) or click on the first cell and press enter. This should make the second cell reference the value of the first cell.

Another good method for setting a DropDownList style combobox:

Combox1.SelectedIndex = Combox1.FindStringExact("test1")

It's a language abstraction - some languages have both, some one, some neither.

In the case of C++, the code is not run in either the stack or the heap. You can test what happens if you run out of heap memory by repeatingly calling new to allocate memory in a loop without calling delete to free it it. But make a system backup before doing this.

I´d like to mention, that I used spring boot version 1.4.0 and since this version you can only write:

@Component
public class MongoConnection {

@Value("${spring.data.mongodb.host}")
private String mongoHost;

@Value("${spring.data.mongodb.port}")
private int mongoPort;

@Value("${spring.data.mongodb.database}")
private String mongoDB;
}

Then inject class whenever you want.

EDIT:

From nowadays I would use @ConfigurationProperties because you are able to inject property values in your POJOs. Keep hierarchical sort above your properties. Moreover, you can put validations above POJOs attributes and so on. Take a look at the link

Updated html for the newer bootstrap

    .table-hover > tbody > tr.danger:hover > td {
     background-color: red !important;
}
.table-hover > tbody > tr.warning:hover > td {
     background-color: yellow !important;
}
.table-hover > tbody > tr.success:hover > td {
     background-color: blue !important;
}

You can use length to see if your selector matched anything.

if ($('#MyId').length) {
    // do your stuff
}

The gist

In Node.js, __dirname is always the directory in which the currently executing script resides (see this). So if you typed __dirname into /d1/d2/myscript.js, the value would be /d1/d2.

By contrast, . gives you the directory from which you ran the node command in your terminal window (i.e. your working directory) when you use libraries like path and fs. Technically, it starts out as your working directory but can be changed using process.chdir().

The exception is when you use . with require(). The path inside require is always relative to the file containing the call to require.

For example...

Let's say your directory structure is

/dir1
  /dir2
    pathtest.js

and pathtest.js contains

var path = require("path");
console.log(". = %s", path.resolve("."));
console.log("__dirname = %s", path.resolve(__dirname));

and you do

cd /dir1/dir2
node pathtest.js

you get

. = /dir1/dir2
__dirname = /dir1/dir2

Your working directory is /dir1/dir2 so that's what . resolves to. Since pathtest.js is located in /dir1/dir2 that's what __dirname resolves to as well.

However, if you run the script from /dir1

cd /dir1
node dir2/pathtest.js

you get

. = /dir1
__dirname = /dir1/dir2

In that case, your working directory was /dir1 so that's what . resolved to, but __dirname still resolves to /dir1/dir2.

Using . inside require...

If inside dir2/pathtest.js you have a require call into include a file inside dir1 you would always do

require('../thefile')

because the path inside require is always relative to the file in which you are calling it. It has nothing to do with your working directory.

Try this it is working fine for me..

EditText.setInputType(0);
EditText.setFilters(new InputFilter[] {new InputFilter()
{
@Override
public CharSequence filter(CharSequence source, int start,
                            int end, Spanned dest, int dstart, int dend) 
{
return source.length() < 1 ? dest.subSequence(dstart, dend) : "";

}
}
});

I had the same problem while creating AVD with 4.2.2 images, I resolved it by doing the following :

1. Check if there exist a "default" folder in adt-bundle-windows-x86_64-20131030\sdk\system-images\android-17.

2. If it exists then move the contents(downloaded system images) of the "default" folder to adt-bundle-windows-x86_64-20131030\sdk\system-images\android-17.

Hope this helps.
