• It is a very easy to use method in C++11.
• We can use std::chrono::high_resolution_clock from header
• We can write a method to print the method execution time in a much readable form.

For example, to find the all the prime numbers between 1 and 100 million, it takes approximately 1 minute and 40 seconds. So the execution time get printed as:

Execution Time: 1 Minutes, 40 Seconds, 715 MicroSeconds, 715000 NanoSeconds

The code is here:

#include <iostream>
#include <chrono>

using namespace std;
using namespace std::chrono;

typedef high_resolution_clock Clock;
typedef Clock::time_point ClockTime;

void findPrime(long n, string file);
void printExecutionTime(ClockTime start_time, ClockTime end_time);

int main()
{
    long n = long(1E+8);  // N = 100 million

    ClockTime start_time = Clock::now();

    // Write all the prime numbers from 1 to N to the file "prime.txt"
    findPrime(n, "C:\\prime.txt"); 

    ClockTime end_time = Clock::now();

    printExecutionTime(start_time, end_time);
}

void printExecutionTime(ClockTime start_time, ClockTime end_time)
{
    auto execution_time_ns = duration_cast<nanoseconds>(end_time - start_time).count();
    auto execution_time_ms = duration_cast<microseconds>(end_time - start_time).count();
    auto execution_time_sec = duration_cast<seconds>(end_time - start_time).count();
    auto execution_time_min = duration_cast<minutes>(end_time - start_time).count();
    auto execution_time_hour = duration_cast<hours>(end_time - start_time).count();

    cout << "\nExecution Time: ";
    if(execution_time_hour > 0)
    cout << "" << execution_time_hour << " Hours, ";
    if(execution_time_min > 0)
    cout << "" << execution_time_min % 60 << " Minutes, ";
    if(execution_time_sec > 0)
    cout << "" << execution_time_sec % 60 << " Seconds, ";
    if(execution_time_ms > 0)
    cout << "" << execution_time_ms % long(1E+3) << " MicroSeconds, ";
    if(execution_time_ns > 0)
    cout << "" << execution_time_ns % long(1E+6) << " NanoSeconds, ";
}

Just reference the System.Web assembly and then call: HttpServerUtility.HtmlEncode

I'm sure that the above answers work perfectly. However, I had the difficulty of adding the double quotes as my bash lines where closer to 100. So, the following way helped me. (In a nutshell, no double quotes around each line of the shell)

Also, when I had "bash '''#!/bin/bash" within steps, I got the following error java.lang.NoSuchMethodError: No such DSL method '**bash**' found among steps

pipeline {
    agent none

    stages {

        stage ('Hello') {
            agent any

            steps {
                echo 'Hello, '

                sh '''#!/bin/bash

                    echo "Hello from bash"
                    echo "Who I'm $SHELL"
                '''
            }
        }
    }
}

The result of the above execution is

Here you can find info on how to upgrade to v3: http://tosbourn.com/2013/08/javascript/upgrading-from-bootstraps-typeahead-to-typeahead-js/

Here are some examples too: http://twitter.github.io/typeahead.js/examples/

if your using python 3.4.1 just write this line from tkinter import * this will put everything in the module into the default namespace of your program. in fact instead of referring to say a button like tkinter.Button you just type Button

Simply restarting Visual Studio worked for me.

There's always LINQ:

t.GetProperties().Where(
    p=>p.GetCustomAttributes(typeof(MyAttribute), true).Length != 0)

Here's how to look in the documentation.

First, you're dealing with IO, so look in the java.io package.

There are two classes that look interesting: FileFilter and FileNameFilter. When I clicked on the first, it showed me that there was a a listFiles() method in the File class. And the documentation for that method says:

Returns an array of abstract pathnames denoting the files in the directory denoted by this abstract pathname.

Scrolling up in the File JavaDoc, I see the constructors. And that's really all I need to be able to create a File instance and call listFiles() on it. Scrolling still further, I can see some information about how files are named in different operating systems.

You have to set the path. See here.

You want a multiple attribute selector

$("input[type='checkbox'][name='ProductCode']").each(function(){ ...

or

$("input:checkbox[name='ProductCode']").each(function(){ ...

It would be better to use a CSS class to identify those that you want to select however as a lot of the modern browsers implement the document.getElementsByClassName method which will be used to select elements and be much faster than selecting by the name attribute

I don't like "hacks" but in a quick pinch for a deadline I have done this

<li ng-if="edit === false && filtered.length === 0">
    <p ng-if="group.title != 'Dispatcher News'" style="padding: 5px">No links in group.</p>
</li>

Yes, I have another inner nested ng-if, I just didn't like too many conditions on one line.

To get that information in SQL Management Studio, right click on the database, then select Reports --> Standard Reports --> Disk Usage by Table.

Okay, of course the question has been answered, but no-one seems to notice the third line of your code. It continuosly bugged me.

    <?php
    mysqli_connect("localhost","root","","web_table");
    mysql_select_db("web_table") or die(mysql_error());

for some reason, you made a mysqli connection to server, but you are trying to make a mysql connection to database.To get going, rather use

       $link = mysqli_connect("localhost","root","","web_table");
       mysqli_select_db ($link , "web_table" ) or die.....

or for where i began

     <?php $connection = mysqli_connect("localhost","root","","web_table");       
      global $connection; // global connection to databases - kill it once you're done

or just query with a $connection parameter as the other argument like above. Get rid of that third line.

You could use the JavaScriptSerializer class, check this article to build an useful extension method.

Code from article:

namespace ExtensionMethods
{
    public static class JSONHelper
    {
        public static string ToJSON(this object obj)
        {
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            return serializer.Serialize(obj);
        }

        public static string ToJSON(this object obj, int recursionDepth)
        {
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            serializer.RecursionLimit = recursionDepth;
            return serializer.Serialize(obj);
        }
    }
}

Usage:

using ExtensionMethods;

...

List<Person> people = new List<Person>{
                   new Person{ID = 1, FirstName = "Scott", LastName = "Gurthie"},
                   new Person{ID = 2, FirstName = "Bill", LastName = "Gates"}
                   };


string jsonString = people.ToJSON();

You cannot add headers but, if you just need to pass values to the server at the moment of the connection, you can specify a query string part on the url:

var ws = new WebSocket("ws://example.com/service?key1=value1&key2=value2");

That URL is valid but - of course - you'll need to modify your server code to parse it.

Old Answer (July 2016):

You can't directly debug Chrome for iOS due to restrictions on the published WKWebView apps, but there are a few options already discussed in other SO threads:

1. If you can reproduce the issue in Safari as well, then use Remote Debugging with Safari Web Inspector. This would be the easiest approach.

2. WeInRe allows some simple debugging, using a simple client-server model. It's not fully featured, but it may well be enough for your problem. See instructions on set up here.

3. You could try and create a simple WKWebView browser app (some instructions here), or look for an existing one on GitHub. Since Chrome uses the same rendering engine, you could debug using that, as it will be close to what Chrome produces.

There's a "bug" opened up for WebKit: Allow Web Inspector usage for release builds of WKWebView. If and when we get an API to WKWebView, Chrome for iOS would be debuggable.

Update January 2018:

Since my answer back in 2016, some work has been done to improve things.

There is a recent project called RemoteDebug iOS WebKit Adapter, by some of the Microsoft team. It's an adapter that handles the API differences between Webkit Remote Debugging Protocol and Chrome Debugging Protocol, and this allows you to debug iOS WebViews in any app that supports the protocol - Chrome DevTools, VS Code etc.

Check out the getting started guide in the repo, which is quite detailed.

If you are interesting, you can read up on the background and architecture here.

create table employee
(
   empid int,
   empname varchar(40),
   designation varchar(30),
   hiredate datetime, 
   Bsalary int,
   depno constraint emp_m foreign key references department(depno)
)

We should have an primary key to create foreign key or relationship between two or more table .

The reason to prefer Promises over callback functions is to have multiple callbacks and to avoid the problems like Callback Hell.

Callback hell (for more details, refer http://callbackhell.com/): Asynchronous javascript, or javascript that uses callbacks, is hard to get right intuitively. A lot of code ends up looking like this:

asyncCall(function(err, data1){
    if(err) return callback(err);       
    anotherAsyncCall(function(err2, data2){
        if(err2) return calllback(err2);
        oneMoreAsyncCall(function(err3, data3){
            if(err3) return callback(err3);
            // are we done yet?
        });
    });
});

With Promises above code can be rewritten as below:

asyncCall()
.then(function(data1){
    // do something...
    return anotherAsyncCall();
})
.then(function(data2){
    // do something...  
    return oneMoreAsyncCall();    
})
.then(function(data3){
    // the third and final async response
})
.fail(function(err) {
    // handle any error resulting from any of the above calls    
})
.done();

 ssh user@machine 'bash -s' < local_script.sh

or you can just

 ssh user@machine "remote command to run" 

For simplicity, if you do not want send a message, try this

$new_string = substr( $dynamicstring, -min( strlen( $dynamicstring ), 7 ) );

There are multiple options to set variables in Hive.

If you're looking to set Hive variable from inside the Hive shell, you can set it using hivevar. You can set string or integer datatypes. There are no problems with them.

SET hivevar:which_date=20200808;
select ${which_date};

If you're planning to set variables from shell script and want to pass those variables into your Hive script (HQL) file, you can use --hivevar option while calling hive or beeline command.

# shell script will invoke script like this
beeline --hivevar tablename=testtable -f select.hql

-- select.hql file
select * from <dbname>.${tablename};

Assuming you don't count connection set-up (as you indicated in your update), it strongly depends on the cipher chosen. Network overhead (in terms of bandwidth) will be negligible. CPU overhead will be dominated by cryptography. On my mobile Core i5, I can encrypt around 250 MB per second with RC4 on a single core. (RC4 is what you should choose for maximum performance.) AES is slower, providing "only" around 50 MB/s. So, if you choose correct ciphers, you won't manage to keep a single current core busy with the crypto overhead even if you have a fully utilized 1 Gbit line. [Edit: RC4 should not be used because it is no longer secure. However, AES hardware support is now present in many CPUs, which makes AES encryption really fast on such platforms.]

Connection establishment, however, is different. Depending on the implementation (e.g. support for TLS false start), it will add round-trips, which can cause noticable delays. Additionally, expensive crypto takes place on the first connection establishment (above-mentioned CPU could only accept 14 connections per core per second if you foolishly used 4096-bit keys and 100 if you use 2048-bit keys). On subsequent connections, previous sessions are often reused, avoiding the expensive crypto.

So, to summarize:

Transfer on established connection:

• Delay: nearly none
• CPU: negligible
• Bandwidth: negligible

First connection establishment:

• Delay: additional round-trips
• Bandwidth: several kilobytes (certificates)
• CPU on client: medium
• CPU on server: high

Subsequent connection establishments:

• Delay: additional round-trip (not sure if one or multiple, may be implementation-dependant)
• Bandwidth: negligible
• CPU: nearly none

This is what I use to control headers/caching, I'm not an Apache pro, so let me know if there is room for improvement, but I know that this has been working well on all of my sites for some time now.

Mod_expires

http://httpd.apache.org/docs/2.2/mod/mod_expires.html

This module controls the setting of the Expires HTTP header and the max-age directive of the Cache-Control HTTP header in server responses. The expiration date can set to be relative to either the time the source file was last modified, or to the time of the client access.

These HTTP headers are an instruction to the client about the document's validity and persistence. If cached, the document may be fetched from the cache rather than from the source until this time has passed. After that, the cache copy is considered "expired" and invalid, and a new copy must be obtained from the source.

# BEGIN Expires
<ifModule mod_expires.c>
ExpiresActive On
ExpiresDefault "access plus 1 seconds"
ExpiresByType text/html "access plus 1 seconds"
ExpiresByType image/gif "access plus 2592000 seconds"
ExpiresByType image/jpeg "access plus 2592000 seconds"
ExpiresByType image/png "access plus 2592000 seconds"
ExpiresByType text/css "access plus 604800 seconds"
ExpiresByType text/javascript "access plus 216000 seconds"
ExpiresByType application/x-javascript "access plus 216000 seconds"
</ifModule>
# END Expires

Mod_headers

http://httpd.apache.org/docs/2.2/mod/mod_headers.html

This module provides directives to control and modify HTTP request and response headers. Headers can be merged, replaced or removed.

# BEGIN Caching
<ifModule mod_headers.c>
<filesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|swf)$">

I had this problem on jdk1.6.0_37. This is the only JDE/JRE on my system. I don't know why, but the following solved the problem:

Project -> Properties -> Java Build Path - > Libraries

Switch radio button from Execution environment to Alernate JRE. This selects the same jdk1.6.0_37, but after clean/build the compile error disappeared.

Maybe clarification in answer from ram (Mar 16 at 9:00) has to do something with that.

serialize() is the best method. @ Christopher Parker say that Nickf's anwser accomplishes more, however it does not take into account that the form may contain textarea and select menus. It is far better to use serialize() and then manipulate that as you need to. Data from serialize() can be used in either an Ajax post or get, so there is no issue there.

You can do it with javascript/jquery:

<script>
    function runScript(e) {
        if (e.keyCode == 13) {
            $("#myButton").click(); //jquery
            document.getElementById("myButton").click(); //javascript
        }
    }
</script>

<asp:textbox id="txtUsername" runat="server" onkeypress="return runScript(event)" />

<asp:LinkButton id="myButton" text="Login" runat="server" />

You are not adding the object to the session, instead you are adding it to the request.
What you need is:

HttpSession session = request.getSession();
session.setAttribute("MySessionVariable", param);

In Servlets you have 4 scopes where you can store data.

1. Application
2. Session
3. Request
4. Page

Make sure you understand these. For more look here

Why not use an cache that stores each marker object and references an ID?

var markerCache= {};
var idGen= 0;

function codeAddress(addr, contentStr){
    // create marker
    // store
    markerCache[idGen++]= marker;
}

Edit: of course this relies on a numeric index system that doesn't offer a length property like an array. You could of course prototype the Object object and create a length, etc for just such a thing. OTOH, generating a unique ID value (MD5, etc) of each address might be the way to go.

I solved this by changing the expression to:

reverse( 'django-admin', args=["%s/%s/%s/" % (app_label, model_name, object_id)] )

This requires/assumes that the root url conf has a name for the "admin" url handler, mainly that name is "django-admin",

i.e. in the root url conf:

url(r'^admin/(.*)', admin.site.root, name='django-admin'),

It seems to be working, but I'm not sure of its cleanness.

And ofcourse you can do:

# a.py
MY_CONSTANT = ...

# b.py
from a import *
print MY_CONSTANT

In Java 8 you can do this

Files.walk(Paths.get("/path/to/folder"))
     .filter(Files::isRegularFile)
     .forEach(System.out::println);

which will print all files in a folder while excluding all directories. If you need a list, the following will do:

Files.walk(Paths.get("/path/to/folder"))
     .filter(Files::isRegularFile)
     .collect(Collectors.toList())

If you want to return List<File> instead of List<Path> just map it:

List<File> filesInFolder = Files.walk(Paths.get("/path/to/folder"))
                                .filter(Files::isRegularFile)
                                .map(Path::toFile)
                                .collect(Collectors.toList());

You also need to make sure to close the stream! Otherwise you might run into an exception telling you that too many files are open. Read here for more information.

One way to do this is to insert a dummy column with the sums in order to sort:

In [10]: sum_B_over_A = df.groupby('A').sum().B

In [11]: sum_B_over_A
Out[11]: 
A
bar    0.253652
baz   -2.829711
foo    0.551376
Name: B

in [12]: df['sum_B_over_A'] = df.A.apply(sum_B_over_A.get_value)

In [13]: df
Out[13]: 
     A         B      C  sum_B_over_A
0  foo  1.624345  False      0.551376
1  bar -0.611756   True      0.253652
2  baz -0.528172  False     -2.829711
3  foo -1.072969   True      0.551376
4  bar  0.865408  False      0.253652
5  baz -2.301539   True     -2.829711

In [14]: df.sort(['sum_B_over_A', 'A', 'B'])
Out[14]: 
     A         B      C   sum_B_over_A
5  baz -2.301539   True      -2.829711
2  baz -0.528172  False      -2.829711
1  bar -0.611756   True       0.253652
4  bar  0.865408  False       0.253652
3  foo -1.072969   True       0.551376
0  foo  1.624345  False       0.551376

and maybe you would drop the dummy row:

In [15]: df.sort(['sum_B_over_A', 'A', 'B']).drop('sum_B_over_A', axis=1)
Out[15]: 
     A         B      C
5  baz -2.301539   True
2  baz -0.528172  False
1  bar -0.611756   True
4  bar  0.865408  False
3  foo -1.072969   True
0  foo  1.624345  False

foreach (DataRow dr in dataTable1.Rows) {
    if (/* some condition */)
        dataTable2.Rows.Add(dr.ItemArray);
}

The above example assumes that dataTable1 and dataTable2 have the same number, type and order of columns.

The answer from Joey was not working for me. After executing

  echo ^<?xml version="1.0" encoding="utf-8" ?^> > myfile.xml

I got this error bash: syntax error near unexpected token `>'

This solution worked for me:

 echo "<?xml version=\"1.0\" encoding=\"utf-8\">" > myfile.txt

See also http://www.robvanderwoude.com/escapechars.php

Maybe can help to check that the path to the xsd file has not 'strange' characters like 'é', or similar: I was having the same issue but when I changed to a path without the 'é' the error dissapeared.

Expanding upon the accepted answer, your machine going to sleep, etc. may delay the timer from working. You can get a true time, at the cost of a little processing. This will give a true time left.

<span id="timer"></span>

<script>
var now = new Date();
var timeup = now.setSeconds(now.getSeconds() + 30);
//var timeup = now.setHours(now.getHours() + 1);

var counter = setInterval(timer, 1000);

function timer() {
  now = new Date();
  count = Math.round((timeup - now)/1000);
  if (now > timeup) {
      window.location = "/logout"; //or somethin'
      clearInterval(counter);
      return;
  }
  var seconds = Math.floor((count%60));
  var minutes = Math.floor((count/60) % 60);
  document.getElementById("timer").innerHTML = minutes + ":" + seconds;
}
</script>

if you want to check if your passed string is in string then there is a simple method for that.

string yourStringForCheck= "abc";
string stringInWhichWeCheck= "Test abc abc";

bool isContained = stringInWhichWeCheck.ToLower().IndexOf(yourStringForCheck.ToLower()) > -1;

This boolean value will return if the string is contained or not

writelines() does not add line separators. You can alter the list of strings by using map() to add a new \n (line break) at the end of each string.

items = ['abc', '123', '!@#']
items = map(lambda x: x + '\n', items)
w.writelines(items)

In most recent version of Rails (can't tell which one exactly though), you could use the as_json method :

@post = Post.first
hash = @post.as_json
puts hash.pretty_inspect

Will output :

{ 
  :name => "test",
  :post_number => 20,
  :active => true
}

To go a bit further, you could override that method in order to customize the way your attributes appear, by doing something like this :

class Post < ActiveRecord::Base
  def as_json(*args)
    {
      :name => "My name is '#{self.name}'",
      :post_number => "Post ##{self.post_number}",
    }
  end
end

Then, with the same instance as above, will output :

{ 
  :name => "My name is 'test'",
  :post_number => "Post #20"
}

This of course means you have to explicitly specify which attributes must appear.

Hope this helps.

EDIT :

Also you can check the Hashifiable gem.

You are experiencing this issue for two reasons.

• The JPQL Query is not valid.
• You have not created an association between your entities that the underlying JPQL query can utilize.

When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)

User.java

@Entity
@Table(name="user")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="iduser")
    private Long idUser;

    @Column(name="user_name")
    private String userName;

    @OneToOne()
    @JoinColumn(name="idarea")
    private Area area;

    public Long getIdUser() {
        return idUser;
    }

    public void setIdUser(Long idUser) {
        this.idUser = idUser;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public Area getArea() {
        return area;
    }

    public void setArea(Area area) {
        this.area = area;
    }
}

Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:

@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")

While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.

Area.java

@Entity
@Table(name = "area")
public class Area {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="idarea")
    private Long idArea;

    @Column(name="area_name")
    private String areaName;

    @OneToOne(fetch=FetchType.LAZY, mappedBy="area")

    public void setAreaName(String areaName) {

I just built a sandbox environment with your code and it worked for me. Here is what I used:

<html>
  <head>
    <title>test</title>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
  </head>
  <body>
    <form id="chatTickets" method="post" action="/admin/index.cfm/">
      <input id="ticketID1" type="radio" checked="checked" value="myvalue1" name="ticketID"/>
      <input id="ticketID2" type="radio" checked="checked" value="myvalue2" name="ticketID"/>
    </form>
    <a href="#" title="Load ActiveChat" id="loadActive">Load Active</a>

    <script>
      jQuery("#loadActive").click(function() {
        //I have other code in here that runs before this function call
        writeData();
      });
      function writeData() {
        jQuery("input[name='ticketID']").each(function(i) {
            jQuery(this).attr('disabled', 'disabled');
        });
      }
    </script>
  </body>
</html>

I tested in FF3.5, moving to IE8 now. And it works fine in IE8 too. What browser are you using?

If you are loading the XML file from a remote location, I would check to see if the file is actually being downloaded correctly using a sniffer like Fiddler.

I wrote a quick console app to run your code and parse the file and it works fine for me.

Public - means that the class (program) is available for use by any other class.

Static - creates a class. Can also be applied to variables and methods,making them class methods/variables instead of just local to a particular instance of the class.

Void - this means that no product is returned when the class completes processing. Compare this with helper classes that provide a return value to the main class,these operate like functions; these do not have void in the declaration.

Consider also just doing mkdir -p data/images in your Makefile, if the directory needs to be there during build.

If that's not good enough, just create an empty file in data/images and ignore data.

touch data/images/.gitignore
git add data/images/.gitignore
git commit -m "Add empty .gitignore to keep data/images around"
echo data >> .gitignore
git add .gitignore
git commit -m "Add data to .gitignore"

It's a hex number and is 16 decimal.

From the PHP manual:

The size of an integer is platform-dependent, although a maximum value of about two billion is the usual value (that's 32 bits signed). PHP does not support unsigned integers. Integer size can be determined using the constant PHP_INT_SIZE, and maximum value using the constant PHP_INT_MAX since PHP 4.4.0 and PHP 5.0.5.

64-bit platforms usually have a maximum value of about 9E18, except on Windows prior to PHP 7, where it was always 32 bit.

Here is a solution with shell parameter expansion that replaces multiple contiguous occurrences with a single _:

$ var=AxxBCyyyDEFzzLMN
$ echo "${var//+([xyz])/_}"
A_BC_DEF_LMN

Notice that the +(pattern) pattern requires extended pattern matching, turned on with

shopt -s extglob

Alternatively, with the -s ("squeeze") option of tr:

$ tr -s xyz _ <<< "$var"
A_BC_DEF_LMN

Have you tried this?:

    $string = '';
    while($row = mysql_fetch_array($result))
    {
    //this will combine all the results into one string
    $string .= '<img src="'.$row['name'].'" />
                <div>'.$row['name'].'</div>
                <div>'.$row['title'].'</div>
                <div>'.$row['description'].'</div>
                <div>'.$row['link'].'</div><br />';

    //or this will add the individual result in an array
 /*
     $yourHtml[] = $row;
*/
    }

then you echo the $tring to the place you want it to be

<div id="place_here">
   <?php echo $string; ?>
   <?php 
     //or
    /*
      echo '<img src="'.$yourHtml[0]['name'].'" />;//change the index, or you just foreach loop it
    */
    ?>
</div>

did you try 'localhost/phpmyadmin' ? (notice the lowercase)

PHPMyAdmin tends to have inconsistent directory names across its versions/distributions.

Edit: Confirm the URL by checking the name of the root folder!

If the config was the primary issue (and it may still be nthary) you would get a php error, not a http "Object not found" error,

As for the config error, here are some steps to correct it:

1. Once you have confirmed which case your PHPMyAdmin is in, confirm that your config.inc.php is located in its root directory.

2. If it is, rename it to something else as a backup. Then copy the config.sample.inc.php (in the same directory) and rename it to config.inc.php

3. Check if it works.

4. If its does, then open up both the new config.inc.php (that works) and the backup you took earlier of your old one. Compare them and copy/replace the important parts that you want to carry over, the file (in its default state) isn't that long and it should be relatively easy to do so.

N.B. If the reason that you want your old config is because of security setup that you once had, I would definitely suggest still using the security wizard built into XAMPP so that you can be assured that you have the right configuration for the right version. There is no guarantee that different XAMPP/PHPMyAdmin versions implement security/anything in the same way.

XAMPP Security Wizard

Under the Links Tab ==> Edit the URL Item ==> Under the URL (Type the Web address)- format the value as follows:

Example: if the URL = http://www.abc.com ==> then suffix the value with ==>

• #openinnewwindow/,'" target="http://www.abc.com'

SO, the final value should read as ==> http://www.abc.com#openinnewwindow/,'" target="http://www.abc.com'

DONE ==> this will open the URL in New Window

Simply use title in tag like

<i class="fa fa-edit" title="Edit Mode"></i>

This will show 'Edit Mode' when hover that icon.

You can get the keyboard height by subscribing to the UIKeyboardWillShowNotification notification. (Assuming you want to know what the height will be before it's shown).

Swift 4

NotificationCenter.default.addObserver(
    self,
    selector: #selector(keyboardWillShow),
    name: UIResponder.keyboardWillShowNotification,
    object: nil
)

@objc func keyboardWillShow(_ notification: Notification) {
    if let keyboardFrame: NSValue = notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue {
        let keyboardRectangle = keyboardFrame.cgRectValue
        let keyboardHeight = keyboardRectangle.height
    }
}

Swift 3

NotificationCenter.default.addObserver(
    self,
    selector: #selector(keyboardWillShow),
    name: NSNotification.Name.UIKeyboardWillShow,
    object: nil
)

@objc func keyboardWillShow(_ notification: Notification) {
    if let keyboardFrame: NSValue = notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue {
        let keyboardRectangle = keyboardFrame.cgRectValue
        let keyboardHeight = keyboardRectangle.height
    }
}

Swift 2

NSNotificationCenter.defaultCenter().addObserver(self, selector: "keyboardWillShow:", name: UIKeyboardWillShowNotification, object: nil)

func keyboardWillShow(notification: NSNotification) {
        let userInfo: NSDictionary = notification.userInfo!
        let keyboardFrame: NSValue = userInfo.valueForKey(UIKeyboardFrameEndUserInfoKey) as! NSValue
        let keyboardRectangle = keyboardFrame.CGRectValue()
        let keyboardHeight = keyboardRectangle.height
    }

Just iterate over the elements. Like this:

for (int i = numElements - 1; i >= 0; i--) 
    cout << array[i];

Note: As Maxim Egorushkin pointed out, this could overflow. See his comment below for a better solution.

I faced the same problem and solved this like i described below: As You have downloaded and installed dnspython successfully so

1. Enter into folder dnspython
2. You will find dns directory, now copy it
3. Then paste it to inside site-packages directory

That's all. Now your problem will go

If dnspython isn't installed you can install it this way :

1. go to your python installation folder site-packages directory
2. open cmd here and enter the command : pip install dnspython

Now, dnspython will be installed successfully.

Use GSON for converting POJO to JSONObject. Refer here.

For converting JSONObject to POJO, just call the setter method in the POJO and assign the values directly from the JSONObject.

From https://system.data.sqlite.org:

System.Data.SQLite is an ADO.NET adapter for SQLite.

System.Data.SQLite was started by Robert Simpson. Robert still has commit privileges on this repository but is no longer an active contributor. Development and maintenance work is now mostly performed by the SQLite Development Team. The SQLite team is committed to supporting System.Data.SQLite long-term.

"System.Data.SQLite is the original SQLite database engine and a complete ADO.NET 2.0 provider all rolled into a single mixed mode assembly. It is a complete drop-in replacement for the original sqlite3.dll (you can even rename it to sqlite3.dll). Unlike normal mixed assemblies, it has no linker dependency on the .NET runtime so it can be distributed independently of .NET."

It even supports Mono.

I've a same problem. After move machine from restore of Time Machine, on another host. There problem it's that ssh key for vagrant it's not your key, it's a key on Homestead directory.

Solution for me:

• Use vagrant / vagrant for access ti VM of Homestead
• vagrant ssh-config for see config of ssh

run on terminal

vagrant ssh-config
Host default
HostName 127.0.0.1
User vagrant
Port 2222
UserKnownHostsFile /dev/null
StrictHostKeyChecking no
PasswordAuthentication no
IdentityFile "/Users/MYUSER/.vagrant.d/insecure_private_key"
IdentitiesOnly yes
LogLevel FATAL
ForwardAgent yes

Create a new pair of SSH keys

ssh-keygen -f /Users/MYUSER/.vagrant.d/insecure_private_key

Copy content of public key

cat /Users/MYUSER/.vagrant.d/insecure_private_key.pub

On other shell in Homestead VM Machine copy into authorized_keys

vagrant@homestad:~$ echo 'CONTENT_PASTE_OF_PRIVATE_KEY' >> ~/.ssh/authorized_keys

Now can access with vagrant ssh

Use a public static class and access it from anywhere.

public static class MyGlobals {
    public const string Prefix = "ID_"; // cannot change
    public static int Total = 5; // can change because not const
}

used like so, from master page or anywhere:

string strStuff = MyGlobals.Prefix + "something";
textBox1.Text = "total of " + MyGlobals.Total.ToString();

You don't need to make an instance of the class; in fact you can't because it's static. new Just use it directly. All members inside a static class must also be static. The string Prefix isn't marked static because const is implicitly static by nature.

The static class can be anywhere in your project. It doesn't have to be part of Global.asax or any particular page because it's "global" (or at least as close as we can get to that concept in object-oriented terms.)

You can make as many static classes as you like and name them whatever you want.

Sometimes programmers like to group their constants by using nested static classes. For example,

public static class Globals {
    public static class DbProcedures {
        public const string Sp_Get_Addresses = "dbo.[Get_Addresses]";
        public const string Sp_Get_Names = "dbo.[Get_First_Names]";
    }
    public static class Commands {
        public const string Go = "go";
        public const string SubmitPage = "submit_now";
    }
}

and access them like so:

MyDbCommand proc = new MyDbCommand( Globals.DbProcedures.Sp_Get_Addresses );
proc.Execute();
//or
string strCommand = Globals.Commands.Go;

I was able to solve this entirely in IB:

1. Make constraints to align the center Y of each of your subviews to the bottom edge of the superview.
2. Set the multiplier of each of these constraints to 1/2n, 3/2n, 5/2n, …, n-1/2n where n is the number of subviews you are distributing.

So if you have three labels, set the multipliers to each of those constraints to 0.1666667, 0.5, 0.833333.

var pattern = new RegExp((0|1)[0-9]\/[0-3][0-9]\/(19|20)[0-9]{2});
if(!testdate.match(pattern))
   return false;
else return true;

If you need to increase MySQL Connections without MySQL restart do like below

mysql> show variables like 'max_connections';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 100   |
+-----------------+-------+
1 row in set (0.00 sec)

mysql> SET GLOBAL max_connections = 150;
Query OK, 0 rows affected (0.00 sec)

mysql> show variables like 'max_connections';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| max_connections | 150   |
+-----------------+-------+
1 row in set (0.00 sec)

These settings will change at MySQL Restart.

For permanent changes add below line in my.cnf and restart MySQL

max_connections = 150

I know this is an old question, but I have a solution that isn't listed here.

When you produce the csv add a space after the comma but before your value e.g. , 005,.

This worked to prevent auto date formatting in excel 2007 anyway .

Just matching local ones from an origin with square brackets included. I know it's not as comprehensive but in javascript the other ones had difficult to trace issues primarily that of not working, so this seems to get me what I needed for now. extra capitals A-F aren't needed either.

^\[([0-9a-fA-F]{1,4})(\:{1,2})([0-9a-fA-F]{1,4})(\:{1,2})([0-9a-fA-F]{1,4})(\:{1,2})([0-9a-fA-F]{1,4})(\:{1,2})([0-9a-fA-F]{1,4})\]

Jinnko's version is simplified and better I see.

if you have generic types in your class you should use TypeReference with convertValue().

final ObjectMapper mapper = new ObjectMapper();
final MyPojo<MyGenericType> pojo = mapper.convertValue(map, new TypeReference<MyPojo<MyGenericType>>() {});

Also you can use that to convert a pojo to java.util.Map back.

final ObjectMapper mapper = new ObjectMapper();
final Map<String, Object> map = mapper.convertValue(pojo, new TypeReference<Map<String, Object>>() {});

This is an ancient question, but both module private (one underscore) and class-private (two underscores) mangled variables are now covered in the standard documentation:

The Python Tutorial » Classes » Private Variables

If you are trying to view an extensionless file what worked for me was adding a MIME Type: File name extension: . MIME type: text/plain

This might have some MVC implications, especially if your Static File Handler is above the Extensionless... handlers (under IIS / Handler Mappings) but might be a work around when you only need this temporarily, like activating SSL Certs.

Although using '@' is more appropriate than using '=' for your particular scenario, sometimes I use '=' so that I don't have to remember to use attrs.$observe():

<su-label tooltip="field.su_documentation">{{field.su_name}}</su-label>

Directive:

myApp.directive('suLabel', function() {
    return {
        restrict: 'E',
        replace: true,
        transclude: true,
        scope: {
            title: '=tooltip'
        },
        template: '<label><a href="#" rel="tooltip" title="{{title}}" data-placement="right" ng-transclude></a></label>',
        link: function(scope, element, attrs) {
            if (scope.title) {
                element.addClass('tooltip-title');
            }
        },
    }
});

Fiddle.

With '=' we get two-way databinding, so care must be taken to ensure scope.title is not accidentally modified in the directive. The advantage is that during the linking phase, the local scope property (scope.title) is defined.

Decorators seem better suited to modify the functionality of an entire object (including function objects) versus the functionality of an object method which in general will depend on instance attributes. For example:

def mod_bar(cls):
    # returns modified class

    def decorate(fcn):
        # returns decorated function

        def new_fcn(self):
            print self.start_str
            print fcn(self)
            print self.end_str

        return new_fcn

    cls.bar = decorate(cls.bar)
    return cls

@mod_bar
class Test(object):
    def __init__(self):
        self.start_str = "starting dec"
        self.end_str = "ending dec" 

    def bar(self):
        return "bar"

The output is:

>>> import Test
>>> a = Test()
>>> a.bar()
starting dec
bar
ending dec

I am using ansible 2.5 (2.5.3 exactly), and it seems that the vars file is loaded before the hosts param is executed. So you can set the host in a vars.yml file and just write hosts: {{ host_var }} in your playbook

For example, in my playbook.yml:

---
- hosts: "{{ host_name }}"
  become: yes
  vars_files:
    - vars/project.yml
  tasks:
    ... 

And inside vars/project.yml:

---

# general
host_name: your-fancy-host-name

You can first insert data into blob field and then copy to text field with the folloing function

CREATE OR REPLACE FUNCTION blob2text() RETURNS void AS $$
Declare
    ref record;
    i integer;
Begin
    FOR ref IN SELECT id, blob_field FROM table LOOP

          --  find 0x00 and replace with space    
      i := position(E'\\000'::bytea in ref.blob_field);
      WHILE i > 0 LOOP
        ref.bob_field := set_byte(ref.blob_field, i-1, 20);
        i := position(E'\\000'::bytea in ref.blobl_field);
      END LOOP

    UPDATE table SET field = encode(ref.blob_field, 'escape') WHERE id = ref.id;
    END LOOP;

End; $$ LANGUAGE plpgsql; 

--

SELECT blob2text();

To get the value of the selected item of a listbox then use the following.

For Single Column ListBox: ListBox1.List(ListBox1.ListIndex)

For Multi Column ListBox: ListBox1.Column(column_number, ListBox1.ListIndex)

This avoids looping and is extremely more efficient.

As to my understanding it help your content adjust with different values of font family and font sizes.Thus making your content scalable. As to the issue of inhering font size we can always override by giving a specific font size for the element.

why not using?

location.href='http://www.example.com';

<!DOCTYPE html>_x000D_
<html>_x000D_
_x000D_
<head>_x000D_
  <script>_x000D_
    function goToURL() {_x000D_
      location.href = 'http://google.it';_x000D_
_x000D_
    }_x000D_
  </script>_x000D_
</head>_x000D_

<body>_x000D_
  <a href="javascript:void(0)" onclick="goToURL(); return false;">Go To URL</a>_x000D_

_x000D_
</html>

data="UTF-8 DATA"
udata=data.decode("utf-8")
asciidata=udata.encode("ascii","ignore")

You can just inject the DOCUMENT token into the constructor and use the same functions on it

import { Inject }  from '@angular/core';
import { DOCUMENT } from '@angular/common'; 

@Component({...})
export class AppCmp {
   constructor(@Inject(DOCUMENT) document) {
      document.getElementById('el');
   }
}

Or if the element you want to get is in that component, you can use template references.

You need to use \n inside quotes.

document.getElementById("address_box").value = (title + "\n" + address + "\n" + address2 + "\n" + address3 + "\n" + address4)

\n is called a EOL or line-break, \n is a common EOL marker and is commonly refereed to as LF or line-feed, it is a special ASCII character

this main works in both linux and windows - found it through trial and error and help from others so can't explain why it works, it just does int main(int argc, char** argv)

no tchar.h necessary

and here is the same answer in Wikipedia Main function

In the codebase I'm working with (1 million + lines of code) we had a problem with long startup times, around 60 seconds. We were getting 12000+ FactoryBeanNotInitializedException.

What I did was set a conditional breakpoint in AbstractBeanFactory#doGetBean

catch (BeansException ex) {
   // Explicitly remove instance from singleton cache: It might have been put there
   // eagerly by the creation process, to allow for circular reference resolution.
   // Also remove any beans that received a temporary reference to the bean.
   destroySingleton(beanName);
   throw ex;
}

where it does destroySingleton(beanName) I printed the exception with conditional breakpoint code:

   System.out.println(ex);
   return false;

Apparently this happens when FactoryBeans are involved in a cyclic dependency graph. We solved it by implementing ApplicationContextAware and InitializingBean and manually injecting the beans.

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.InitializingBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

public class A implements ApplicationContextAware, InitializingBean{

    private B cyclicDepenency;
    private ApplicationContext ctx;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext)
            throws BeansException {
        ctx = applicationContext;
    }
    @Override
    public void afterPropertiesSet() throws Exception {
        cyclicDepenency = ctx.getBean(B.class);
    }

    public void useCyclicDependency()
    {
        cyclicDepenency.doSomething();
    }
}

This cut down the startup time to around 15 secs.

So don't always assume that spring can be good at solving these references for you.

For this reason I'd recommend disabling cyclic dependency resolution with AbstractRefreshableApplicationContext#setAllowCircularReferences(false) to prevent many future problems.

This is my answer

#include<stdio.h>
int main()
{int mat[100][100];
int row,column,i,j;
printf("enter how many row and colmn you want:\n \n");
scanf("%d",&row);
scanf("%d",&column);
printf("enter the matrix:");

for(i=0;i<row;i++){
    for(j=0;j<column;j++){
        scanf("%d",&mat[i][j]);
    }

printf("\n");
}

for(i=0;i<row;i++){
    for(j=0;j<column;j++){
        printf("%d \t",mat[i][j]);}

printf("\n");}
}

I just choose an approximate value for the row and column. My selected row or column will not cross the value.and then I scan the matrix element then make it in matrix size.

Make sure you use port 22. Filezilla will default to port 21 for SFTP.

An "incomplete class" is one declared but not defined. E.g.

class Wielrenner;

as opposed to

class Wielrenner
{
    /* class members */
};

You need to #include "wielrenner.h" in dokter.ccp

I already said that I was new to exec() function. After doing some more digging, I came upon 2>&1 which needs to be added at the end of command in exec().

Thanks @mattosmat for pointing it out in the comments too. I did not try this at once because you said it is a Linux command, I am on Windows.

So, what I have discovered, the command is actually executing in the back-end. That is why I could not see it actually running, which I was expecting to happen.

For all of you, who had similar problem, my advise is to use that command. It will point out all the errors and also tell you info/details about execution.

exec('some_command 2>&1', $output);
print_r($output);  // to see the response to your command

Thanks for all the help guys, I appreciate it ;)

Moq (and other DynamicProxy-based mocking frameworks) are unable to mock anything that is not a virtual or abstract method.

Sealed/static classes/methods can only be faked with Profiler API based tools, like Typemock (commercial) or Microsoft Moles (free, known as Fakes in Visual Studio 2012 Ultimate /2013 /2015).

Alternatively, you could refactor your design to abstract calls to static methods, and provide this abstraction to your class via dependency injection. Then you'd not only have a better design, it will be testable with free tools, like Moq.

A common pattern to allow testability can be applied without using any tools altogether. Consider the following method:

public class MyClass
{
    public string[] GetMyData(string fileName)
    {
        string[] data = FileUtil.ReadDataFromFile(fileName);
        return data;
    }
}

Instead of trying to mock FileUtil.ReadDataFromFile, you could wrap it in a protected virtual method, like this:

public class MyClass
{
    public string[] GetMyData(string fileName)
    {
        string[] data = GetDataFromFile(fileName);
        return data;
    }

    protected virtual string[] GetDataFromFile(string fileName)
    {
        return FileUtil.ReadDataFromFile(fileName);
    }
}

Then, in your unit test, derive from MyClass and call it TestableMyClass. Then you can override the GetDataFromFile method to return your own test data.

Hope that helps.

Behavior differences

Some differences on Bash 4.3.11:

• POSIX vs Bash extension:

  • [ is POSIX
  • [[ is a Bash extension inspired from Korn shell

• regular command vs magic

  • [ is just a regular command with a weird name.

    ] is just the last argument of [.

  Ubuntu 16.04 actually has an executable for it at /usr/bin/[ provided by coreutils, but the bash built-in version takes precedence.

  Nothing is altered in the way that Bash parses the command.

  In particular, < is redirection, && and || concatenate multiple commands, ( ) generates subshells unless escaped by \, and word expansion happens as usual.

  • [[ X ]] is a single construct that makes X be parsed magically. <, &&, || and () are treated specially, and word splitting rules are different.

    There are also further differences like = and =~.

  In Bashese: [ is a built-in command, and [[ is a keyword: https://askubuntu.com/questions/445749/whats-the-difference-between-shell-builtin-and-shell-keyword

• <

  • [[ a < b ]]: lexicographical comparison
  • [ a \< b ]: Same as above. \ required or else does redirection like for any other command. Bash extension.
  • expr x"$x" \< x"$y" > /dev/null or [ "$(expr x"$x" \< x"$y")" = 1 ]: POSIX equivalents, see: How to test strings for lexicographic less than or equal in Bash?

• && and ||

  • [[ a = a && b = b ]]: true, logical and
  • [ a = a && b = b ]: syntax error, && parsed as an AND command separator cmd1 && cmd2
  • [ a = a ] && [ b = b ]: POSIX reliable equivalent
  • [ a = a -a b = b ]: almost equivalent, but deprecated by POSIX because it is insane and fails for some values of a or b like ! or ( which would be interpreted as logical operations

• (

  • [[ (a = a || a = b) && a = b ]]: false. Without ( ), would be true because [[ && ]] has greater precedence than [[ || ]]
  • [ ( a = a ) ]: syntax error, () is interpreted as a subshell
  • [ \( a = a -o a = b \) -a a = b ]: equivalent, but (), -a, and -o are deprecated by POSIX. Without \( \) would be true because -a has greater precedence than -o
  • { [ a = a ] || [ a = b ]; } && [ a = b ] non-deprecated POSIX equivalent. In this particular case however, we could have written just: [ a = a ] || [ a = b ] && [ a = b ] because the || and && shell operators have equal precedence unlike [[ || ]] and [[ && ]] and -o, -a and [

• word splitting and filename generation upon expansions (split+glob)

  • x='a b'; [[ $x = 'a b' ]]: true, quotes not needed
  • x='a b'; [ $x = 'a b' ]: syntax error, expands to [ a b = 'a b' ]
  • x='*'; [ $x = 'a b' ]: syntax error if there's more than one file in the current directory.
  • x='a b'; [ "$x" = 'a b' ]: POSIX equivalent

• =

  • [[ ab = a? ]]: true, because it does pattern matching (* ? [ are magic). Does not glob expand to files in current directory.
  • [ ab = a? ]: a? glob expands. So may be true or false depending on the files in the current directory.
  • [ ab = a\? ]: false, not glob expansion
  • = and == are the same in both [ and [[, but == is a Bash extension.
  • case ab in (a?) echo match; esac: POSIX equivalent
  • [[ ab =~ 'ab?' ]]: false, loses magic with '' in Bash 3.2 and above and provided compatibility to bash 3.1 is not enabled (like with BASH_COMPAT=3.1)
  • [[ ab? =~ 'ab?' ]]: true

• =~

  • [[ ab =~ ab? ]]: true, POSIX extended regular expression match, ? does not glob expand
  • [ a =~ a ]: syntax error. No bash equivalent.
  • printf 'ab\n' | grep -Eq 'ab?': POSIX equivalent (single line data only)
  • awk 'BEGIN{exit !(ARGV[1] ~ ARGV[2])}' ab 'ab?': POSIX equivalent.

Recommendation: always use []

There are POSIX equivalents for every [[ ]] construct I've seen.

If you use [[ ]] you:

• lose portability
• force the reader to learn the intricacies of another bash extension. [ is just a regular command with a weird name, no special semantics are involved.

DECLARE @day CHAR(2)

Oh, I just found that command on PostgreSQL forum:

SELECT * FROM pg_stat_activity;

Do you want the name of the class as a string?

instance.__class__.__name__

Very simple:

Just use the below formation###

rules_id = ["9","10"]

sql2 = "SELECT * FROM attendance_rules_staff WHERE id in"+str(tuple(rules_id))

note the str(tuple(rules_id)).

I was experiencing the same problem on OS X. I've solved it now. I post my solution here for anyone who has the similar issue.

Firstly, I set the password for root in mysql client:

shell> mysql -u root
mysql> FLUSH PRIVILEGES;
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MY_PASSWORD');

Then, I checked the version info:

shell> /usr/local/mysql/bin/mysqladmin -u root -p version
...
Server version    5.6.26
Protocol version  10
Connection        Localhost via UNIX socket
UNIX socket       /tmp/mysql.sock
Uptime:           11 min 0 sec
...

Finally, I changed the connect_type parameter from tcp to socket and added the parameter socket in config.inc.php:

$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['connect_type'] = 'socket';
$cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';

Here's the simple check, and creates the dir if doesn't exists:

## Provide the dir name(i.e sub dir) that you want to create under main dir:
output_dir <- file.path(main_dir, sub_dir)

if (!dir.exists(output_dir)){
dir.create(output_dir)
} else {
    print("Dir already exists!")
}

You can redirect output to a file and then read the file:

return = WshShell.Run("cmd /c C:\snmpset -c ... > c:\temp\output.txt", 0, true)

Set fso  = CreateObject("Scripting.FileSystemObject")
Set file = fso.OpenTextFile("c:\temp\output.txt", 1)
text = file.ReadAll
file.Close

It depends on how you set the defaults for the dropdown. Use selected value, but you have to set the selected value. For instance, I populate the datasource with the name and id field for the table/list. I set the selected value to the id field and the display to the name. When I select, I get the id field. I use this to search a relational table and find an entity/record.

this one works in ubuntu This command will cre android update project -p "project full path"

I had the same issue. And I solved it by changing the remote branch's path from https://github.com/YourName/RepoName to [email protected]:YourName/RepoName.git in the repo's settings of the client app.

Note in 2018: readAsBinaryString is outdated. For use cases where previously you'd have used it, these days you'd use readAsArrayBuffer (or in some cases, readAsDataURL) instead.

readAsBinaryString says that the data must be represented as a binary string, where:

...every byte is represented by an integer in the range [0..255].

JavaScript originally didn't have a "binary" type (until ECMAScript 5's WebGL support of Typed Array* (details below) -- it has been superseded by ECMAScript 2015's ArrayBuffer) and so they went with a String with the guarantee that no character stored in the String would be outside the range 0..255. (They could have gone with an array of Numbers instead, but they didn't; perhaps large Strings are more memory-efficient than large arrays of Numbers, since Numbers are floating-point.)

If you're reading a file that's mostly text in a western script (mostly English, for instance), then that string is going to look a lot like text. If you read a file with Unicode characters in it, you should notice a difference, since JavaScript strings are UTF-16** (details below) and so some characters will have values above 255, whereas a "binary string" according to the File API spec wouldn't have any values above 255 (you'd have two individual "characters" for the two bytes of the Unicode code point).

If you're reading a file that's not text at all (an image, perhaps), you'll probably still get a very similar result between readAsText and readAsBinaryString, but with readAsBinaryString you know that there won't be any attempt to interpret multi-byte sequences as characters. You don't know that if you use readAsText, because readAsText will use an encoding determination to try to figure out what the file's encoding is and then map it to JavaScript's UTF-16 strings.

You can see the effect if you create a file and store it in something other than ASCII or UTF-8. (In Windows you can do this via Notepad; the "Save As" as an encoding drop-down with "Unicode" on it, by which looking at the data they seem to mean UTF-16; I'm sure Mac OS and *nix editors have a similar feature.) Here's a page that dumps the result of reading a file both ways:

If I use that with a "Testing 1 2 3" file stored in UTF-16, here are the results I get:

Text (13):

54 65 73 74 69 6e 67 20 31 20 32 20 33

Binary (28):

ff fe 54 00 65 00 73 00 74 00 69 00 6e 00 67 00 20 00 31 00 20 00 32 00 20 00 33 00

As you can see, readAsText interpreted the characters and so I got 13 (the length of "Testing 1 2 3"), and readAsBinaryString didn't, and so I got 28 (the two-byte BOM plus two bytes for each character).

* XMLHttpRequest.response with responseType = "arraybuffer" is supported in HTML 5.

** "JavaScript strings are UTF-16" may seem like an odd statement; aren't they just Unicode? No, a JavaScript string is a series of UTF-16 code units; you see surrogate pairs as two individual JavaScript "characters" even though, in fact, the surrogate pair as a whole is just one character. See the link for details.

In C++ you cannot initialize any variables directly while the declaration. For this we've to use the concept of constructors.
See this example:-

#include <iostream>

using namespace std;

class A
{
    public:
  const int x;  
  
  A():x(0) //initializing the value of x to 0
  {
      //constructor
  }
};

int main()
{
    A a; //creating object
   cout << "Value of x:- " <<a.x<<endl; 
   
   return 0;
}

Hope it would help you!

As @qiao said, you can't use __dirname in the node repl. However, if you need need this value in the console, you can use path.resolve() or path.dirname(). Although, path.dirname() will just give you a "." so, probably not that helpful. Be sure to require('path').

There is one difference - you can't use String without using System; beforehand.

Just simply write BETWEEN '{$startDate}' AND '{$endDate}' in where condition as

->where("date BETWEEN '{$startDate}' AND '{$endDate}'")

For me it was a wrong maven dependency deceleration, so here is the correct way:

for sqljdbc4 use: sqljdbc4 dependency

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc4</artifactId>
    <version>4.0</version>
</dependency>

for sqljdbc42 use: sqljdbc42 dependency

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc42</artifactId>
    <version>6.0.8112</version>
</dependency>

The item from iterrows() is not a Series, but a tuple of (index, Series), so you can unpack the tuple in the for loop like so:

for (idx, row) in df.iterrows():
    print(row.loc['A'])
    print(row.A)
    print(row.index)

#0.890618586836
#0.890618586836
#Index(['A', 'B', 'C', 'D'], dtype='object')

Will this be simpler for handling the day boundary case? :)

TimeSpan start = TimeSpan.Parse("22:00");  // 10 PM
TimeSpan end = TimeSpan.Parse("02:00");    // 2 AM
TimeSpan now = DateTime.Now.TimeOfDay;

bool bMatched = now.TimeOfDay >= start.TimeOfDay &&
                now.TimeOfDay < end.TimeOfDay;
// Handle the boundary case of switching the day across mid-night
if (end < start)
    bMatched = !bMatched;

if(bMatched)
{
    // match found, current time is between start and end
}
else
{
    // otherwise ... 
}

public static String lpad(String str, int requiredLength, char padChar) {
    if (str.length() > requiredLength) {
        return str;
    } else {
        return new String(new char[requiredLength - str.length()]).replace('\0', padChar) + str;
    }
}

Just declare it outside class definition.

If your namespace's name is X, you will be able to access the enum's values by X.card_suit

If you have not defined a namespace for this enum, just call them by card_suit.Clubs etc.

This solution doesn't require an import:

tuple(map(lambda x, y: x + y, tuple1, tuple2))

Use story borad : select the label to set number of lines to zero......Or Refer this

grep

For non-greedy match in grep you could use a negated character class. In other words, try to avoid wildcards.

For example, to fetch all links to jpeg files from the page content, you'd use:

grep -o '"[^" ]\+.jpg"'

To deal with multiple line, pipe the input through xargs first. For performance, use ripgrep.

I wonder why no one is suggesting routerLink and routerLinkActive (Angular 7)

<a [routerLink]="[ '/resources' ]" routerLinkActive="currentUrl!='/resources'">

I removed the href and now using this. When using href, it was going to the base url or reloading the same route again.

Several things here.

First off, you're defining your CSS in 3 places!

In line, in the head and externally. I suggest you only choose one. I'm going to suggest externally.

I suggest you update your code in your ASP form from

<td style="background-color: #A3A3A3; color: #FFFFFF; font-family: 'Arial Black'; font-size: large; font-weight: bold;" 
        class="style6">

to this:

<td  class="style6">

And then update your css too

.style6
    {
        height: 79px; background-color: #A3A3A3; color: #FFFFFF; font-family: 'Arial Black'; font-size: large; font-weight: bold;
    }

This removes the inline.

Now, to move it from the head of the webForm.

Line numbers are OK if you can guarantee the position of what you want. Over the years, my favorite flavor of this has been something like this:

sed "/First Line of Text/,/Last Line of Text/d" filename

which deletes all lines from the first matched line to the last match, including those lines.

Use sed -n with "p" instead of "d" to print those lines instead. Way more useful for me, as I usually don't know where those lines are.

it works with postgresql

UPDATE application

    FROM
        application_history
    WHERE
        application.id = application_history.application_id
    AND application_history.application_status_id = 8
);

Use return operator:

function FUNCT {
  if [ blah is false ]; then
    return 1 # or return 0, or even you can omit the argument.
  else
    keep running the function
  fi
}

I want to add that if you are trying to do this for files/directories in a git repository to track if they have changed, then this is the best approach:

git log -1 --format=format:%H --full-diff <file_or_dir_name>

And if it's not a git-directory/repo, then answer by @ire_and_curses is probably the best bet:

tar c <dir_name> | md5sum

However, please note that tar command will change the output hash if you run it in a different OS and stuff. If you want to be immune to that, this is the best approach, even though it doesn't look very elegant on first sight:

find <dir_name> -type f -print0 | sort -z | xargs -0 md5sum | md5sum | awk '{ print $1 }'

I don't know any native cmdlet in powershell but you can use com object instead:

$WshShell = New-Object -comObject WScript.Shell
$Shortcut = $WshShell.CreateShortcut("$Home\Desktop\ColorPix.lnk")
$Shortcut.TargetPath = "C:\Program Files (x86)\ColorPix\ColorPix.exe"
$Shortcut.Save()

you can create a powershell script save as set-shortcut.ps1 in your $pwd

param ( [string]$SourceExe, [string]$DestinationPath )

$WshShell = New-Object -comObject WScript.Shell
$Shortcut = $WshShell.CreateShortcut($DestinationPath)
$Shortcut.TargetPath = $SourceExe
$Shortcut.Save()

and call it like this

Set-ShortCut "C:\Program Files (x86)\ColorPix\ColorPix.exe" "$Home\Desktop\ColorPix.lnk"

If you want to pass arguments to the target exe, it can be done by:

#Set the additional parameters for the shortcut  
$Shortcut.Arguments = "/argument=value"  

before $Shortcut.Save().

For convenience, here is a modified version of set-shortcut.ps1. It accepts arguments as its second parameter.

param ( [string]$SourceExe, [string]$ArgumentsToSourceExe, [string]$DestinationPath )
$WshShell = New-Object -comObject WScript.Shell
$Shortcut = $WshShell.CreateShortcut($DestinationPath)
$Shortcut.TargetPath = $SourceExe
$Shortcut.Arguments = $ArgumentsToSourceExe
$Shortcut.Save()

When I disabled ReSharper, Visual Studio was also giving the same error, even though the project built successfully. What I did to resolve the issue was:

1. Remove the project from the solution.
2. Right-click the solution, Add Existing Project, select the project file and add it again.

After performing these steps, the syntax errors went away in Visual Studio, and after I enabled ReSharper again, it also had no errors.

By default . (any character) does not match newline characters.

This means you can simply match zero or more of any character then append the end tag.

Find: <li><a href="#">.* Replace: $0</a>

This workaround was written in 2009 when IOS 3.0 was released. It no longer applies.

I ran into the exact same problem, in the end I had to wind up using

nameField.contentInset = UIEdgeInsetsMake(-4,-8,0,0);

where nameField is a UITextView. The font I happened to be using was Helvetica 16 point. Its only a custom solution for the particular field size I was drawing. This makes the left offset flush with the left side, and the top offset where I want it for the box its draw in.

In addition, this only seems to apply to UITextViews where you are using the default aligment, ie.

nameField.textAlignment = NSTextAlignmentLeft;

Align to the right for example and the UIEdgeInsetsMake seems to have no impact on the right edge at all.

At very least, using the .contentInset property allows you to place your fields with the "correct" positions, and accommodate the deviations without offsetting your UITextViews.

I've got this problem for long that I cant get my android emulator or device connect to the debugger while both the console and the emulator were displaying waiting for connecting to the debugger.

And configuration for debug inside eclipse also confused me so much before, but today, i got this problem solved, by the following steps:

When you want to debug a android project, for instance, mypro. you would right click on it in the "Package Explorer". Then choose "Debug as"-->"Android Application".

Then the emulator might stop at the "Waiting for connecting to debugger"(or something else similar to this).

Then you need to connect to the debugger yourself by click "DDMS" to open the DDMS perspective, and click "Devices" tab.

Then you can see a list of processes that are running on your emulator or device.

Double click on the one which you are debugging, then change to the Debug perspective, you can see the debugger is connected and you could debug your program. That's how I solved this problem.

By the way, my OS is Win7 32-bit. Eclipse's version is Helios Service Release 2. Android SDK is rev. 16 and platform-tools' 10.

Update.

I found that it is the problem of my TCP/IP configuration. The debugger can't be connected when i assign a static IP address(for access to internet).

So every time when the debugger is unable to connect, I always do the following steps:

1.close current eclipse window.

2.change the config of IP address to dynamic, it means getting a IP address by DHCP.

3.open up the eclipse again.

then the debugger is able to be connected. I thought it might be a issue of the internal mechanism of java debugger which is using socket connection.

I faced the same issue and solved it by setting the Collation to utf8_general_ci for each column.

Here is another one liner using lambdas (create column with constant value = 10)

df['newCol'] = df.apply(lambda x: 10, axis=1)

before

df
    A           B           C
1   1.764052    0.400157    0.978738
2   2.240893    1.867558    -0.977278
3   0.950088    -0.151357   -0.103219

after

df
        A           B           C           newCol
    1   1.764052    0.400157    0.978738    10
    2   2.240893    1.867558    -0.977278   10
    3   0.950088    -0.151357   -0.103219   10

Merging two linked lists (especially two doubly linked lists) is much faster than merging two arrays (assuming the merge is destructive). The former takes O(1), the latter takes O(n).

EDIT: To clarify, I meant "merging" here in the unordered sense, not as in merge sort. Perhaps "concatenating" would have been a better word.

My answer
Use nested for loops to provide break points to the for /l loop.

for %%a in (0 1 2 3 4 5 6 7 8 9) do (
   for %%b in (0 1 2 3 4 5 6 7 8 9) do (
      for /l %%c in (1,1,10) do (
         if not exist %%a%%b%%c goto :continue
      )
   )
)
:continue

Explanation The code must be tweaked significantly to properly use the nested loops. For example, what is written will have leading zeros.
"Regular" for loops can be immediately broken out of with a simple goto command, where for /l loops cannot. This code's innermost for /l loop cannot be immediately broken, but an overall break point is present after every 10 iterations (as written). The innermost loop doesn't have to be 10 iterations -- you'll just have to account for the math properly if you choose to do 100 or 1000 or 2873 for that matter (if math even matters to the loop).

History I found this question while trying to figure out why a certain script was running slowly. It turns out I used multiple loops with a traditional loop structure:

set cnt=1
:loop
if "%somecriteria%"=="finished" goto :continue
rem do some things here
set /a cnt += 1
goto :loop

:continue
echo the loop ran %cnt% times

This script file had become somewhat long and it was being run from a network drive. This type of loop file was called maybe 20 times and each time it would loop 50-100 times. The script file was taking too long to run. I had the bright idea of attempting to convert it to a for /l loop. The number of needed iterations is unknown, but less than 10000. My first attempt was this:

setlocal enabledelayedexpansion
set cnt=1
for /l %%a in (1,1,10000) do (
   if "!somecriteria!"=="finished" goto :continue
   rem do some things here
   set /a cnt += 1
)

:continue
echo the loop ran %cnt% times

With echo on, I quickly found out that the for /l loop still did ... something ... without actually doing anything. It ran much faster, but still slower than I thought it could/should. Therefore I found this question and ended up with the nested loop idea presented above.

Side note It turns out that the for /l loop can be sped up quite a bit by simply making sure it doesn't have any output. I was able to do this for a noticeable speed increase:

setlocal enabledelayedexpansion
set cnt=1
@for /l %%a in (1,1,10000) do @(
   if "!somecriteria!"=="finished" goto :continue
   rem do some things here
   set /a cnt += 1
) > nul

:continue
echo the loop ran %cnt% times

Yes, they are very different in theory, and in implementation.

Lexers are used to recognize "words" that make up language elements, because the structure of such words is generally simple. Regular expressions are extremely good at handling this simpler structure, and there are very high-performance regular-expression matching engines used to implement lexers.

Parsers are used to recognize "structure" of a language phrases. Such structure is generally far beyond what "regular expressions" can recognize, so one needs "context sensitive" parsers to extract such structure. Context-sensitive parsers are hard to build, so the engineering compromise is to use "context-free" grammars and add hacks to the parsers ("symbol tables", etc.) to handle the context-sensitive part.

Neither lexing nor parsing technology is likely to go away soon.

They may be unified by deciding to use "parsing" technology to recognize "words", as is currently explored by so-called scannerless GLR parsers. That has a runtime cost, as you are applying more general machinery to what is often a problem that doesn't need it, and usually you pay for that in overhead. Where you have lots of free cycles, that overhead may not matter. If you process a lot of text, then the overhead does matter and classical regular expression parsers will continue to be used.

There is not only 1 %SystemRoot%\System32 on Windows x64. There are 2 such directories.

The real %SystemRoot%\System32 directory is for 64-bit applications. This directory contains a 64-bit cmd.exe.

But there is also %SystemRoot%\SysWOW64 for 32-bit applications. This directory is used if a 32-bit application accesses %SystemRoot%\System32. It contains a 32-bit cmd.exe.

32-bit applications can access %SystemRoot%\System32 for 64-bit applications by using the alias %SystemRoot%\Sysnative in path.

For more details see the Microsoft documentation about File System Redirector.

So the subdirectory run was created either in %SystemRoot%\System32 for 64-bit applications and 32-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\SysWOW64 which is %SystemRoot%\System32 for 32-bit cmd.exe or the subdirectory run was created in %SystemRoot%\System32 for 32-bit applications and 64-bit cmd is run for which this directory does not exist because there is no subdirectory run in %SystemRoot%\System32 as this subdirectory exists only in %SystemRoot%\SysWOW64.

The following code could be used at top of the batch file in case of subdirectory run is in %SystemRoot%\System32 for 64-bit applications:

@echo off
set "SystemPath=%SystemRoot%\System32"
if not "%ProgramFiles(x86)%" == "" if exist %SystemRoot%\Sysnative\* set "SystemPath=%SystemRoot%\Sysnative"

Every console application in System32\run directory must be executed with %SystemPath% in the batch file, for example %SystemPath%\run\YourApp.exe.

How it works?

There is no environment variable ProgramFiles(x86) on Windows x86 and therefore there is really only one %SystemRoot%\System32 as defined at top.

But there is defined the environment variable ProgramFiles(x86) with a value on Windows x64. So it is additionally checked on Windows x64 if there are files in %SystemRoot%\Sysnative. In this case the batch file is processed currently by 32-bit cmd.exe and only in this case %SystemRoot%\Sysnative needs to be used at all. Otherwise %SystemRoot%\System32 can be used also on Windows x64 as when the batch file is processed by 64-bit cmd.exe, this is the directory containing the 64-bit console applications (and the subdirectory run).

Note: %SystemRoot%\Sysnative is not a directory! It is not possible to cd to %SystemRoot%\Sysnative or use if exist %SystemRoot%\Sysnative or if exist %SystemRoot%\Sysnative\. It is a special alias existing only for 32-bit executables and therefore it is necessary to check if one or more files exist on using this path by using if exist %SystemRoot%\Sysnative\cmd.exe or more general if exist %SystemRoot%\Sysnative\*.

Something like the standard Collection.toArray(T[]) should do what you need (note that ArrayList implements Collection):

TypeA[] array = a.toArray(new TypeA[a.size()]);

On a side note, you should consider defining a to be of type List<TypeA> rather than ArrayList<TypeA>, this avoid some implementation specific definition that may not really be applicable for your application.

Also, please see this question about the use of a.size() instead of 0 as the size of the array passed to a.toArray(TypeA[])

It's the "frame" or "range" clause of window functions, which are part of the SQL standard and implemented in many databases, including Teradata.

A simple example would be to calculate the average amount in a frame of three days. I'm using PostgreSQL syntax for the example, but it will be the same for Teradata:

WITH data (t, a) AS (
  VALUES(1, 1),
        (2, 5),
        (3, 3),
        (4, 5),
        (5, 4),
        (6, 11)
)
SELECT t, a, avg(a) OVER (ORDER BY t ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING)
FROM data
ORDER BY t

... which yields:

t  a  avg
----------
1  1  3.00
2  5  3.00
3  3  4.33
4  5  4.00
5  4  6.67
6 11  7.50

As you can see, each average is calculated "over" an ordered frame consisting of the range between the previous row (1 preceding) and the subsequent row (1 following).

When you write ROWS UNBOUNDED PRECEDING, then the frame's lower bound is simply infinite. This is useful when calculating sums (i.e. "running totals"), for instance:

WITH data (t, a) AS (
  VALUES(1, 1),
        (2, 5),
        (3, 3),
        (4, 5),
        (5, 4),
        (6, 11)
)
SELECT t, a, sum(a) OVER (ORDER BY t ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW)
FROM data
ORDER BY t

yielding...

t  a  sum
---------
1  1    1
2  5    6
3  3    9
4  5   14
5  4   18
6 11   29

Here's another very good explanations of SQL window functions.

I ran Visual Studio in Administrator mode and it worked for me :) Also, ensure that the app.config file which you are using for writing WCF configuration must be in the project where "ServiceHost" class is used, and not in actual WCF service project.

No, if you are strictly speaking about regular expressions and not including some regular expression implementations that are actually context free grammars.

There is one limitation of regular expressions which makes it impossible to write a regex that matches all and only regexes. You cannot match implementations such as braces which are paired. Regexes use many such constructs, let's take [] as an example. Whenever there is an [ there must be a matching ], which is simple enough for a regex "\[.*\]".

What makes it impossible for regexes is that they can be nested. How can you write a regex that matches nested brackets? The answer is you can't without an infinitely long regex. You can match any number of nested parenthesis through brute force but you can't ever match an arbitrarily long set of nested brackets.

This capability is often referred to as counting, because you're counting the depth of the nesting. A regex by definition does not have the capability to count.

I ended up writing "Regular Expression Limitations" about this.

It has limitation that not collapsing long inline whitespace, but it is definitely portable and respects layout like webbrowser.

static string HtmlToPlainText(string html) {
  string buf;
  string block = "address|article|aside|blockquote|canvas|dd|div|dl|dt|" +
    "fieldset|figcaption|figure|footer|form|h\\d|header|hr|li|main|nav|" +
    "noscript|ol|output|p|pre|section|table|tfoot|ul|video";

  string patNestedBlock = $"(\\s*?</?({block})[^>]*?>)+\\s*";
  buf = Regex.Replace(html, patNestedBlock, "\n", RegexOptions.IgnoreCase);

  // Replace br tag to newline.
  buf = Regex.Replace(buf, @"<(br)[^>]*>", "\n", RegexOptions.IgnoreCase);

  // (Optional) remove styles and scripts.
  buf = Regex.Replace(buf, @"<(script|style)[^>]*?>.*?</\1>", "", RegexOptions.Singleline);

  // Remove all tags.
  buf = Regex.Replace(buf, @"<[^>]*(>|$)", "", RegexOptions.Multiline);

  // Replace HTML entities.
  buf = WebUtility.HtmlDecode(buf);
  return buf;
}

Try this,

add inplace=True

import numpy as np
df.replace(np.NaN, ' ', inplace=True)

You can also set language at runtime

sqldeveloper.exe --AddVMOption=-Duser.language=en

to avoid editing sqldeveloper.conf every time you install new version.

Insert this in your Makefile

 $(MAKE) -C $(KDIR) M=$(PWD) modules_install                      

 it will install the module in the directory /lib/modules/<var>/extra/
 After make , insert module with modprobe module_name (without .ko extension)

OR

After your normal make, you copy module module_name.ko into   directory  /lib/modules/<var>/extra/

then do modprobe module_name (without .ko extension)

function relativepath($to){
    $a=explode("/",$_SERVER["PHP_SELF"] );
    $index= array_search("$to",$a);
    $str=""; 
    for ($i = 0; $i < count($a)-$index-2; $i++) {
        $str.= "../";
    }
    return $str;
    }

Here is the best solution i made about that, you just need to specify at which level you want to stop, but the problem is that you have to use this folder name one time.

You can divide column of dtype timedelta by np.timedelta64(1, 'D'), but output is not int, but float, because NaN values:

Using ES6 syntax does not work in node, unfortunately, you have to have babel apparently to make the compiler understand syntax such as export or import.

npm install babel-cli --save

Now we need to create a .babelrc file, in the babelrc file, we’ll set babel to use the es2015 preset we installed as its preset when compiling to ES5.

At the root of our app, we’ll create a .babelrc file. $ npm install babel-preset-es2015 --save

At the root of our app, we’ll create a .babelrc file.

{  "presets": ["es2015"] }

Hope it works ... :)

Yes, It is required to add libraries after the source files/objects files. This command will solve the problem:

gcc -static -L/usr/lib -I/usr/lib main.c -ltommath

A little risky, but you could run a curl POST command with the values from the form from the JMX console, its URL and http authentication (if required):

curl -s -X POST --user 'myuser:mypass'
  --data "action=invokeOp&name=App:service=ThisServiceOp&methodIndex=3&arg0=value1&arg1=value1&submit=Invoke"
  http://yourhost.domain.com/jmx-console/HtmlAdaptor

Beware: the method index may change with changes to the software. And the implementation of the web form could change.

The above is based on source of the JMX service page for the operation you want to perform:

http://yourhost.domain.com/jmx-console/HtmlAdaptor?action=inspectMBean&name=YourJMXServiceName

Source of the form:

form method="post" action="HtmlAdaptor">
   <input type="hidden" name="action" value="invokeOp">
   <input type="hidden" name="name" value="App:service=ThisServiceOp">
   <input type="hidden" name="methodIndex" value="3">

Use subprocess.Popen:

import subprocess
process = subprocess.Popen(['ls', '-a'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = process.communicate()
print(out)

Note that communicate blocks until the process terminates. You could use process.stdout.readline() if you need the output before it terminates. For more information see the documentation.

It is possible but, before git 2.9.3 (august 2016), a git push would print the full url used when pushing back to the cloned repo.
That would include your username and password!

But no more: See commit 68f3c07 (20 Jul 2016), and commit 882d49c (14 Jul 2016) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 71076e1, 08 Aug 2016)}

push: anonymize URL in status output

Commit 47abd85 (fetch: Strip usernames from url's before storing them, 2009-04-17, Git 1.6.4) taught fetch to anonymize URLs.
The primary purpose there was to avoid sticking passwords in merge-commit messages, but as a side effect, we also avoid printing them to stderr.

The push side does not have the merge-commit problem, but it probably should avoid printing them to stderr. We can reuse the same anonymizing function.

Note that for this to come up, the credentials would have to appear either on the command line or in a git config file, neither of which is particularly secure.
So people should be switching to using credential helpers instead, which makes this problem go away.

But that's no excuse not to improve the situation for people who for whatever reason end up using credentials embedded in the URL.

As others have stated, you'll need to override the editor.tokenColorCustomizations or the workbench.colorCustomizations setting in the settings.json file. Here you can choose a base theme, like Abyss, and only override the things you want to change. You can either override very few things like the function, string colors etc. very easily.

E.g. for workbench.colorCustomizations

"workbench.colorCustomizations": {
    "[Default Dark+]": {
        "editor.background": "#130e293f",
    }
}

E.g. for editor.tokenColorCustomizations:

"editor.tokenColorCustomizations": {
    "[Abyss]": {
        "functions": "#FF0000",
        "strings": "#FF0000"
    }
}
// Don't do this, looks horrible.

However, deep customisations like change the colour of the var keyword will require you to provide the override values under the textMateRules key.

E.g. below:

"editor.tokenColorCustomizations": {
    "[Abyss]": {
        "textMateRules": [
            {
                "scope": "keyword.operator",
                "settings": {
                    "foreground": "#FFFFFF"
                }
            },
            {
                "scope": "keyword.var",
                "settings": {
                    "foreground": "#2871bb",
                    "fontStyle": "bold"
                }
            }
        ]
    }
}

You can also override globally across themes:

"editor.tokenColorCustomizations": {
    "textMateRules": [
        {
            "scope": [
                //following will be in italics (=Pacifico)
                "comment",
                "entity.name.type.class", //class names
                "keyword", //import, export, return…
                //"support.class.builtin.js", //String, Number, Boolean…, this, super
                "storage.modifier", //static keyword
                "storage.type.class.js", //class keyword
                "storage.type.function.js", // function keyword
                "storage.type.js", // Variable declarations
                "keyword.control.import.js", // Imports
                "keyword.control.from.js", // From-Keyword
                //"entity.name.type.js", // new … Expression
                "keyword.control.flow.js", // await
                "keyword.control.conditional.js", // if
                "keyword.control.loop.js", // for
                "keyword.operator.new.js", // new
            ],
            "settings": {
                "fontStyle": "italic"
            }
        }
    ]
}

Instead of WorksheetFunction.Vlookup, you can use Application.Vlookup. If you set a Variant equal to this it returns Error 2042 if no match is found. You can then test the variant - cellNum in this case - with IsError:

Sub test()
Dim ws As Worksheet: Set ws = Sheets("2012")
Dim rngLook As Range: Set rngLook = ws.Range("A:M")
Dim currName As String
Dim cellNum As Variant

'within a loop
currName = "Example"
cellNum = Application.VLookup(currName, rngLook, 13, False)
If IsError(cellNum) Then
    MsgBox "no match"
Else
    MsgBox cellNum
End If
End Sub

The Application versions of the VLOOKUP and MATCH functions allow you to test for errors without raising the error. If you use the WorksheetFunction version, you need convoluted error handling that re-routes your code to an error handler, returns to the next statement to evaluate, etc. With the Application functions, you can avoid that mess.

The above could be further simplified using the IIF function. This method is not always appropriate (e.g., if you have to do more/different procedure based on the If/Then) but in the case of this where you are simply trying to determinie what prompt to display in the MsgBox, it should work:

cellNum = Application.VLookup(currName, rngLook, 13, False)
MsgBox IIF(IsError(cellNum),"no match", cellNum)

Consider those methods instead of On Error ... statements. They are both easier to read and maintain -- few things are more confusing than trying to follow a bunch of GoTo and Resume statements.

I have tested the suggested solutions, they should all work:

select * from dual where (105 = to_number('105'))

=> delivers one dummy row

select * from dual where (10 = to_number('105'))

=> empty result

select * from dual where ('105' = to_char(105))

=> delivers one dummy row

select * from dual where ('105' = to_char(10))

=> empty result

If you revise your regular expression like this:

drupal-6.14/(?=sites(?!/all|/default)).*
             ^^

...then it will match all inputs that contain drupal-6.14/ followed by sites followed by anything other than /all or /default. For example:

drupal-6.14/sites/foo
drupal-6.14/sites/bar
drupal-6.14/sitesfoo42
drupal-6.14/sitesall

Changing ?= to ?! to match your original regex simply negates those matches:

drupal-6.14/(?!sites(?!/all|/default)).*
             ^^

So, this simply means that drupal-6.14/ now cannot be followed by sites followed by anything other than /all or /default. So now, these inputs will satisfy the regex:

drupal-6.14/sites/all
drupal-6.14/sites/default
drupal-6.14/sites/all42

But, what may not be obvious from some of the other answers (and possibly your question) is that your regex will also permit other inputs where drupal-6.14/ is followed by anything other than sites as well. For example:

drupal-6.14/foo
drupal-6.14/xsites

Conclusion: So, your regex basically says to include all subdirectories of drupal-6.14 except those subdirectories of sites whose name begins with anything other than all or default.

It's possible with JavaScript.

5.In the Format Cells box, click Custom in the Category list. 6.In the Type box, at the top of the list of formats, type [h]:mm;@ and then click OK. (That’s a colon after [h], and a semicolon after mm.) YOu can then add hours. The format will be in the Type list the next time you need it.

From MS, works well.

 atan2(vector1.y - vector2.y, vector1.x - vector2.x)

is the angle between the difference vector (connecting vector2 and vector1) and the x-axis, which is problably not what you meant.

The (directed) angle from vector1 to vector2 can be computed as

angle = atan2(vector2.y, vector2.x) - atan2(vector1.y, vector1.x);

and you may want to normalize it to the range [0, 2 p):

if (angle < 0) { angle += 2 * M_PI; }

or to the range (-p, p]:

if (angle > M_PI)        { angle -= 2 * M_PI; }
else if (angle <= -M_PI) { angle += 2 * M_PI; }

You can fetch the URL in your template like this:

<p>URL of this page: {{ request.get_full_path }}</p>

or by

{{ request.path }} if you don't need the extra parameters.

Some precisions and corrections should be brought to hypete's and Igancio's answers, I'll just summarize the whole idea here, for future reference.

If you need the request variable in the template, you must add the 'django.core.context_processors.request' to the TEMPLATE_CONTEXT_PROCESSORS settings, it's not by default (Django 1.4).

You must also not forget the other context processors used by your applications. So, to add the request to the other default processors, you could add this in your settings, to avoid hard-coding the default processor list (that may very well change in later versions):

from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS as TCP

TEMPLATE_CONTEXT_PROCESSORS = TCP + (
    'django.core.context_processors.request',
)

Then, provided you send the request contents in your response, for example as this:

from django.shortcuts import render_to_response
from django.template import RequestContext

def index(request):
    return render_to_response(
        'user/profile.html',
        { 'title': 'User profile' },
        context_instance=RequestContext(request)
    )

You need to plug it into the task scheduler, such that it is launched after login of a user, using a user account that has administrative access on the system, with the highest privileges that are afforded to processes launched by that account.

This is the implementation that is used to autostart processes with administrative privileges when logging in as an ordinary user.

I've used it to launch the 'OpenVPN GUI' helper process which needs elevated privileges to work correctly, and thus would not launch properly from the registry key.

From the command line, you can create the task from an XML description of what you want to accomplish; so for example we have this, exported from my system, which would start notepad with the highest privileges when i log in:

<?xml version="1.0" encoding="UTF-16"?>

this answer should really be moved over to one of the other stackexchange sites, as it's not actually a programming question per se.

1. create textview in ur layout

2. paste this code in ur MainActivity

   TextView textview=(TextView)findViewById(R.id.textviewid);
   Spannable spannable=new SpannableString("Hello my name is sunil");
   spannable.setSpan(new ForegroundColorSpan(Color.BLUE), 0, 5, 
   Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
   textview.setText(spannable);
   //Note:- the 0,5 is the size of colour which u want to give the strring
   //0,5 means it give colour to starting from h and ending with space i.e.(hello), if you want to change size and colour u can easily
   

I had the same problem I used the solution offered above - I dropped the SYNONYM, created a VIEW with the same name as the synonym. it had a select using the dblink , and gave GRANT SELECT to the other schema It worked great.

string.Format("{0}", myObj);

string.Format will format null as an empty string and call ToString() on non-null objects. As I understand it, this is what you were looking for.

use async:false attribute along with url and data. this will help to execute ajax call immediately and u can fetch and use data from server.

function functABC(){
    $.ajax({
        url: 'myPage.php',
        data: {id: id},
        async:false
        success: function(data) {
            return data;
        }
    });
}

You can also set it in the [ServiceBehavior] tag above your class declaration that inherits the interface

[ServiceBehavior(IncludeExceptionDetailInFaults = true)]
public class MyClass:IMyService
{
...
}

Immortal Blue is correct in not disclosing the exeption details to a publicly released version, but for testing purposes this is a handy tool. Always turn back off when releasing.

If you get this error under Linux when running conda using sudo, you might be suffering from bug #7267:

When logging in as non-root user via sudo, e.g. by:

sudo -u myuser -i

conda seems to assume that it is run as root and raises an error.

The only known workaround seems to be: Add the following line to your ~/.bashrc:

unset SUDO_UID SUDO_GID SUDO_USER

...or unset the ENV variables by running the line in a different way before running conda.

If you mistakenly installed anaconda/miniconda as root/via sudo this can also lead to the same error, then you might want to do the following:

sudo chown -R username /path/to/anaconda3

Tested with conda 4.6.14.

To make changes to sudo from putty/bash:

• Type visudo and press enter.
• Navigate to the place you wish to edit using the up and down arrow keys.
• Press insert to go into editing mode.
• Make your changes - for example: user ALL=(ALL) ALL.
• Note - it matters whether you use tabs or spaces when making changes.
• Once your changes are done press esc to exit editing mode.
• Now type :wq to save and press enter.
• You should now be back at bash.
• Now you can press ctrl + D to exit the session if you wish.

After installing it http://meldmerge.org/ I had to tell git where it was:

git config --global merge.tool meld
git config --global diff.tool meld
git config --global mergetool.meld.path “C:\Program Files (x86)\Meld\meld.exe”

And that seems to work. Both merging and diffing with “git difftool” or “git mergetool”

If someone facing issue such as Meld crash after starting (problem indication with python) then you need to set up Meld/lib to your system environment variable as bellow C:\Program Files (x86)\Meld\lib

SELECT * FROM TableName WHERE CHARINDEX('''',ColumnName) > 0 

When you have column with large amount of nvarchar data and millions of records, general 'LIKE' kind of search using percentage symbol will degrade the performance of the SQL operation.

While CHARINDEX inbuilt TSQL function is much more faster and there won't be any performance loss.

Reference SO post for comparative view.

CASE is an expression - it returns a single scalar value (per row). It can't return a complex part of the parse tree of something else, like an ORDER BY clause of a SELECT statement.

It looks like you just need:

ORDER BY 
CASE WHEN TblList.PinRequestCount <> 0 THEN TblList.PinRequestCount END desc,
CASE WHEN TblList.HighCallAlertCount <> 0 THEN TblList.HighCallAlertCount END desc, 
Case WHEN TblList.HighAlertCount <> 0 THEN TblList.HighAlertCount END DESC,
CASE WHEN TblList.MediumCallAlertCount <> 0 THEN TblList.MediumCallAlertCount END DESC,
Case WHEN TblList.MediumAlertCount <> 0 THEN TblList.MediumAlertCount END DESC,
TblList.LastName ASC, TblList.FirstName ASC, TblList.MiddleName ASC

Or possibly:

ORDER BY 
CASE
   WHEN TblList.PinRequestCount <> 0 THEN TblList.PinRequestCount
   WHEN TblList.HighCallAlertCount <> 0 THEN TblList.HighCallAlertCount
   WHEN TblList.HighAlertCount <> 0 THEN TblList.HighAlertCount
   WHEN TblList.MediumCallAlertCount <> 0 THEN TblList.MediumCallAlertCount
   WHEN TblList.MediumAlertCount <> 0 THEN TblList.MediumAlertCount
END desc,
TblList.LastName ASC, TblList.FirstName ASC, TblList.MiddleName ASC

It's a little tricky to tell which of the above (or something else) is what you're looking for because you've a) not explained what actual sort order you're trying to achieve, and b) not supplied any sample data and expected results, from which we could attempt to deduce the actual sort order you're trying to achieve.

This may be the answer we're looking for:

ORDER BY 
CASE
   WHEN TblList.PinRequestCount <> 0 THEN 5
   WHEN TblList.HighCallAlertCount <> 0 THEN 4
   WHEN TblList.HighAlertCount <> 0 THEN 3
   WHEN TblList.MediumCallAlertCount <> 0 THEN 2
   WHEN TblList.MediumAlertCount <> 0 THEN 1
END desc,
CASE
   WHEN TblList.PinRequestCount <> 0 THEN TblList.PinRequestCount
   WHEN TblList.HighCallAlertCount <> 0 THEN TblList.HighCallAlertCount
   WHEN TblList.HighAlertCount <> 0 THEN TblList.HighAlertCount
   WHEN TblList.MediumCallAlertCount <> 0 THEN TblList.MediumCallAlertCount
   WHEN TblList.MediumAlertCount <> 0 THEN TblList.MediumAlertCount
END desc,
TblList.LastName ASC, TblList.FirstName ASC, TblList.MiddleName ASC

You can't hide it, but you can disable it by overriding the CreateParams property of the form.

private const int CP_NOCLOSE_BUTTON = 0x200;
protected override CreateParams CreateParams
{
    get
    {
       CreateParams myCp = base.CreateParams;
       myCp.ClassStyle = myCp.ClassStyle | CP_NOCLOSE_BUTTON ;
       return myCp;
    }
}

You can also use vector::insert.

std::vector<int> v;
int a[5] = {2, 5, 8, 11, 14};

v.insert(v.end(), a, a+5);

Edit:

Of course, in real-world programming you should use:

v.insert(v.end(), a, a+(sizeof(a)/sizeof(a[0])));  // C++03
v.insert(v.end(), std::begin(a), std::end(a));     // C++11

grep has a -P switch allowing to use perl regexp syntax the perl regex allows to look at bytes, using \x.. syntax.

so you can look for a given hex string in a file with: grep -aP "\xdf"

but the outpt won't be very useful; indeed better do a regexp on the hexdump output;

The grep -P can be useful however to just find files matrching a given binary pattern. Or to do a binary query of a pattern that actually happens in text (see for example How to regexp CJK ideographs (in utf-8) )

Edited on 2014/8/25: Here was where I forked it.

Thanks @anvarik.

Here is the JSFiddle. I forgot where I forked this. But this is a good example showing you the difference between = and @

Look at it this way - is it more efficient to throw out the kitchen garbage when the garbage can is at 10% or let it fill up before taking it out?

By not letting it fill up, you are wasting your time walking to and from the garbage bin outside. This analogous to what happens when the GC thread runs - all the managed threads are suspended while it is running. And If I am not mistaken, the GC thread can be shared among multiple AppDomains, so garbage collection affects all of them.

Of course, you might encounter a situation where you won't be adding anything to the garbage can anytime soon - say, if you're going to take a vacation. Then, it would be a good idea to throw out the trash before going out.

This MIGHT be one time that forcing a GC can help - if your program idles, the memory in use is not garbage-collected because there are no allocations.

Add a reference to the Outlook object model in the Visual Basic editor. Then you can use the code below to send an email using outlook.

Sub sendOutlookEmail()
Dim oApp As Outlook.Application
Dim oMail As MailItem
Set oApp = CreateObject("Outlook.application")

Set oMail = oApp.CreateItem(olMailItem)
oMail.Body = "Body of the email"
oMail.Subject = "Test Subject"
oMail.To = "[email protected]"
oMail.Send
Set oMail = Nothing
Set oApp = Nothing


End Sub

The order in which you use middleware in Express matters: middleware declared earlier will get called first, and if it can handle a request, any middleware declared later will not get called.

If express.static is handling the request, you need to move your middleware up:

// need cookieParser middleware before we can do anything with cookies
app.use(express.cookieParser());

// set a cookie
app.use(function (req, res, next) {
  // check if client sent cookie
  var cookie = req.cookies.cookieName;
  if (cookie === undefined) {
    // no: set a new cookie
    var randomNumber=Math.random().toString();
    randomNumber=randomNumber.substring(2,randomNumber.length);
    res.cookie('cookieName',randomNumber, { maxAge: 900000, httpOnly: true });
    console.log('cookie created successfully');
  } else {
    // yes, cookie was already present 
    console.log('cookie exists', cookie);
  } 
  next(); // <-- important!
});

// let static middleware do its job
app.use(express.static(__dirname + '/public'));

Also, middleware needs to either end a request (by sending back a response), or pass the request to the next middleware. In this case, I've done the latter by calling next() when the cookie has been set.

Update

As of now the cookie parser is a seperate npm package, so instead of using

app.use(express.cookieParser());

you need to install it separately using npm i cookie-parser and then use it as:

const cookieParser = require('cookie-parser');
app.use(cookieParser());

In my case, I was using Centos 5.5. I found that the problem was because the mysql service was stopped some how. So I started mysql service with the command:

 /etc/init.d/mysqld start

So.. silly mistake.

$("meta")

Should give you back an array of elements whose tag name is META and then you can iterate over the collection to pick out whatever attributes of the elements you are interested in.

A simple &nbsp; between input fields would do the job easily...

The HttpRequest class represents the request made to the server and has various properties associated with it, such as QueryString.

The ASP.NET run-time parses a request to the server and populates this information for you.

Read HttpRequest Properties for a list of all the potential properties that get populated on you behalf by ASP.NET.

Note: not all properties will be populated, for instance if your request has no query string, then the QueryString will be null/empty. So you should check to see if what you expect to be in the query string is actually there before using it like this:

if (!String.IsNullOrEmpty(Request.QueryString["pID"]))
{
    // Query string value is there so now use it
    int thePID = Convert.ToInt32(Request.QueryString["pID"]);
}

I use this method:

<form name='test' method=post action='sendme.php'>
    <input type=text name='test1'>
    <input type=button value='send' onClick='document.test.submit()'>
    <input type=image src='spacer.gif'>  <!-- <<<< this is the secret! -->
</form>

Basically, I just add an invisible input of type image (where "spacer.gif" is a 1x1 transparent gif).

In this way, I can submit this form either with the 'send' button or simply by pressing enter on the keyboard.

This is the trick!

Because QuerySets implement the Python __or__ operator (|), or union, it just works. As you'd expect, the | binary operator returns a QuerySet so order_by(), .distinct(), and other queryset filters can be tacked on to the end.

combined_queryset = User.objects.filter(income__gte=5000) | User.objects.filter(income__isnull=True)
ordered_queryset = combined_queryset.order_by('-income')

Update 2019-06-20: This is now fully documented in the Django 2.1 QuerySet API reference. More historic discussion can be found in DjangoProject ticket #21333.

SELECT account_id, open_emp_id
         ^^^^        ^^^^
          1           2

FROM account
GROUP BY 1;

In above query GROUP BY 1 refers to the first column in select statement which is account_id.

You also can specify in ORDER BY.

Note : The number in ORDER BY and GROUP BY always start with 1 not with 0.

DateFormatter has some factory date styles for those too lazy to tinker with formatting strings. If you don't need a custom style, here's another option:

extension Date {  
  func asString(style: DateFormatter.Style) -> String {
    let dateFormatter = DateFormatter()
    dateFormatter.dateStyle = style
    return dateFormatter.string(from: self)
  }
}

This gives you the following styles:

short, medium, long, full

Example usage:

let myDate = Date()
myDate.asString(style: .full)   // Wednesday, January 10, 2018
myDate.asString(style: .long)   // January 10, 2018
myDate.asString(style: .medium) // Jan 10, 2018
myDate.asString(style: .short)  // 1/10/18

2014 While is back

Just think logical.

Look at this

for( var index = 0 , length = array.length ; index < length ; index++ ) {

 //do stuff

}

1. Need to create at least 2 variables (index,length)
2. Need to check if the index is smaller than the length
3. Need to increase the index
4. the for loop has 3 parameters

Now tell me why this should be faster than:

var length = array.length;

while( --length ) { //or length--

 //do stuff

}

1. One variable
2. No checks
3. the index is decreased (Machines prefer that)
4. while has only one parameter

I was totally confused when Chrome 28 showed that the for loop is faster than the while. This must have ben some sort of

"Uh, everyone is using the for loop, let's focus on that when developing for chrome."

But now, in 2014 the while loop is back on chrome. it's 2 times faster , on other/older browsers it was always faster.

Lately i made some new tests. Now in real world envoirement those short codes are worth nothing and jsperf can't actually execute properly the while loop, because it needs to recreate the array.length which also takes time.

you CAN'T get the actual speed of a while loop on jsperf.

you need to create your own custom function and check that with window.performance.now()

And yeah... there is no way the while loop is simply faster.

The real problem is actually the dom manipulation / rendering time / drawing time or however you wanna call it.

For example i have a canvas scene where i need to calculate the coordinates and collisions... this is done between 10-200 MicroSeconds (not milliseconds). it actually takes various milliseconds to render everything.Same as in DOM.

BUT

There is another super performant way using the for loop in some cases... for example to copy/clone an array

for(
 var i = array.length ;
 i > 0 ;
 arrayCopy[ --i ] = array[ i ] // doing stuff
);

Notice the setup of the parameters:

1. Same as in the while loop i'm using only one variable
2. Need to check if the index is bigger than 0;
3. As you can see this approach is different vs the normal for loop everyone uses, as i do stuff inside the 3th parameter and i also decrease directly inside the array.

Said that, this confirms that machines like the --

writing that i was thinking to make it a little shorter and remove some useless stuff and wrote this one using the same style:

for(
 var i = array.length ;
 i-- ;
 arrayCopy[ i ] = array[ i ] // doing stuff
);

Even if it's shorter it looks like using i one more time slows down everything. It's 1/5 slower than the previous for loop and the while one.

Note: the ; is very important after the for looo without {}

Even if i just told you that jsperf is not the best way to test scripts .. i added this 2 loops here

http://jsperf.com/caching-array-length/40

And here is another answer about performance in javascript

Custom Event Based solution inspired from Michael Bromley

I wasn't able to make it work with $scope, so I tried with rootScope, maybe a bit more dirty... (especially if you make a refresh on the page that do not register the event)

But I really like the idea of how things are loosely coupled.

I'm using angularjs 1.6.9

index.run.js

angular
.module('myApp')
.run(runBlock);

function runBlock($rootScope, ...)
{
  $rootScope.$on('title-updated', function(event, newTitle) {
    $rootScope.pageTitle = 'MyApp | ' + newTitle;
  });
}

anyController.controller.js

angular
.module('myApp')
.controller('MainController', MainController);

function MainController($rootScope, ...)
{
  //simple way :
  $rootScope.$emit('title-updated', 'my new title');

  // with data from rest call
  TroncQueteurResource.get({id:tronc_queteur_id}).$promise.then(function(tronc_queteur){
  vm.current.tronc_queteur = tronc_queteur;

  $rootScope.$emit('title-updated', moment().format('YYYY-MM-DD') + ' - Tronc '+vm.current.tronc_queteur.id+' - ' +
                                             vm.current.tronc_queteur.point_quete.name + ' - '+
                                             vm.current.tronc_queteur.queteur.first_name +' '+vm.current.tronc_queteur.queteur.last_name
  );
 });

 ....}

index.html

<!doctype html>
<html ng-app="myApp">
  <head>
    <meta charset="utf-8">
    <title ng-bind="pageTitle">My App</title>

It's working for me :)

Handlebars partials take a second parameter which becomes the context for the partial:

{{> person this}}

In versions v2.0.0 alpha and later, you can also pass a hash of named parameters:

{{> person headline='Headline'}}

You can see the tests for these scenarios: https://github.com/wycats/handlebars.js/blob/ce74c36118ffed1779889d97e6a2a1028ae61510/spec/qunit_spec.js#L456-L462 https://github.com/wycats/handlebars.js/blob/e290ec24f131f89ddf2c6aeb707a4884d41c3c6d/spec/partials.js#L26-L32

Found this:

If items(), keys(), values(), iteritems(), iterkeys(), and itervalues() are called with no intervening modifications to the dictionary, the lists will directly correspond.

On 2.x documentation and 3.x documentation.

It is possible to send Emails without using any heavy libraries I have included my example here.

lightweight SMTP Email sender for PHP

https://github.com/jerryurenaa/EZMAIL

Tested in both environments production and development.

and most importantly emails will not go to spam unless your IP is blacklisted by the server.

cheers.

index.html

<!DOCTYPE html>
<html>
   <body>
       <form action="submit.php" method="POST">
         First name: <input type="text" name="firstname" /><br /><br />
         Last name: <input type="text" name="lastname" /><br />
         <input type="submit" value="Submit" />
      </form> 
   </body>
</html>

After that one more file which page you want to display after pressing the submit button

submit.php

<html>
  <body>

    Your First Name is -  <?php echo $_POST["firstname"]; ?><br>
    Your Last Name is -   <?php echo $_POST["lastname"]; ?>

  </body>
</html>

You could use toPrecision() and toFixed() methods of Number type. Check this link How can I format numbers as money in JavaScript?

It's good practice to use a context manager or call close() in case of exceptions during the file saving process. Could happen if your storage backend is down, etc.

Any overwrite behavior should be configured in your storage backend. For example S3Boto3Storage has a setting AWS_S3_FILE_OVERWRITE. If you're using FileSystemStorage you can write a custom mixin.

You might also want to call the model's save method instead of the FileField's save method if you want any custom side-effects to happen, like last-updated timestamps. If that's the case, you can also set the name attribute of the file to the name of the file - which is relative to MEDIA_ROOT. It defaults to the full path of the file which can cause problems if you don't set it - see File.__init__() and File.name.

Here's an example where self is the model instance where my_file is the FileField / ImageFile, calling save() on the whole model instance instead of just FileField:

import os
from django.core.files import File

with open(filepath, 'rb') as fi:
    self.my_file = File(fi, name=os.path.basename(fi.name))
    self.save()

I'm guessing you used Brew to install Node, so the guide here might be helpful http://madebyhoundstooth.com/blog/install-node-with-homebrew-on-os-x/.

You need to ensure that the npm/bin is in your path as it describes export PATH="/usr/local/share/npm/bin:$PATH". This is the location that npm will install the bin stubs for the installed packages.

The nano version will also work as described here http://architectryan.com/2012/10/02/add-to-the-path-on-mac-os-x-mountain-lion/ but a restart of Terminal may be required to have the new path picked up.

There is also proc.time()

You can use in the same way as Sys.time but it gives you a similar result to system.time.

ptm <- proc.time()
#your function here
proc.time() - ptm

the main difference between using

system.time({ #your function here })

is that the proc.time() method still does execute your function instead of just measuring the time... and by the way, I like to use system.time with {} inside so you can put a set of things...

Make Executable your jar and after that double click on it on Mac OS then it works successfully.

sudo chmod +x filename.jar

Try this, I hope this works.

You can copy an iterator to a new list like this:

Iterator<String> iter = list.iterator();
List<String> copy = new ArrayList<String>();
while (iter.hasNext())
    copy.add(iter.next());

That's assuming that the list contains strings. There really isn't a faster way to recreate a list from an iterator, you're stuck with traversing it by hand and copying each element to a new list of the appropriate type.

EDIT :

Here's a generic method for copying an iterator to a new list in a type-safe way:

public static <T> List<T> copyIterator(Iterator<T> iter) {
    List<T> copy = new ArrayList<T>();
    while (iter.hasNext())
        copy.add(iter.next());
    return copy;
}

Use it like this:

List<String> list = Arrays.asList("1", "2", "3");
Iterator<String> iter = list.iterator();
List<String> copy = copyIterator(iter);
System.out.println(copy);
> [1, 2, 3]

'RESTless' is a term not often used.

You can define 'RESTless' as any system that is not RESTful. For that it is enough to not have one characteristic that is required for a RESTful system.

Most systems are RESTless by this definition because they don't implement HATEOAS.

You can use filter .

@Override
    public void doFilter(ServletRequest arg0, ServletResponse arg1, FilterChain arg2) throws IOException, ServletException {
            HttpServletRequest test1=    (HttpServletRequest) arg0;

         test1.getRequestURL()); it gives  http://localhost:8081/applicationName/menu/index.action
         test1.getRequestURI()); it gives applicationName/menu/index.action
         String pathname = test1.getServletPath()); it gives //menu/index.action


        if(pathname.equals("//menu/index.action")){ 
            arg2.doFilter(arg0, arg1); // call to urs servlet or frameowrk managed controller method


            // in resposne 
           HttpServletResponse httpResp = (HttpServletResponse) arg1;
           RequestDispatcher rd = arg0.getRequestDispatcher("another.jsp");     
           rd.forward(arg0, arg1);





    }

donot forget to put <dispatcher>FORWARD</dispatcher> in filter mapping in web.xml

i had this problem yesterday. can you folow the local path in windows explorer?

(C:\users\..\AndroidStudioProjects\SharedPreferencesDemoProject\SharedPreferencesDemo\build\apk\) 

i had to manually create the 'apk' directory in '\build', then the problem was fixed
