I'm guessing that you meant to do this:

The same solution as for Simulate CREATE DATABASE IF NOT EXISTS for PostgreSQL? should work - send a CREATE USER … to \gexec.

Workaround from within psql

SELECT 'CREATE USER my_user'
WHERE NOT EXISTS (SELECT FROM pg_catalog.pg_roles WHERE rolname = 'my_user')\gexec

Workaround from the shell

echo "SELECT 'CREATE USER my_user' WHERE NOT EXISTS (SELECT FROM pg_catalog.pg_roles WHERE rolname = 'my_user')\gexec" | psql

See accepted answer there for more details.

First off; best practice would be to get the users Desktop folder with

string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);

Then you can find all the files with something like

string[] files = Directory.GetFiles(path, "*.txt", SearchOption.AllDirectories);

Note that with the above line you will find all files with a .txt extension in the Desktop folder of the logged in user AND all subfolders.

Then you could copy or move the files by enumerating the above collection like

// For copying...
foreach (string s in files)
{
   File.Copy(s, "C:\newFolder\newFilename.txt");
}

// ... Or for moving
foreach (string s in files)
{
   File.Move(s, "C:\newFolder\newFilename.txt");
}

Please note that you will have to include the filename in your Copy() (or Move()) operation. So you would have to find a way to determine the filename of at least the extension you are dealing with and not name all the files the same like what would happen in the above example.

With that in mind you could also check out the DirectoryInfo and FileInfo classes. These work in similair ways, but you can get information about your path-/filenames, extensions, etc. more easily

Your mysql server may not be running. Below explains how to start the server. This is an excerpt from the README file that comes with the mysql download.

After the installation, you can start up MySQL by running the following commands in a terminal window. You must have administrator privileges to perform this task.

If you have installed the Startup Item, use this command:

 shell> sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
 (ENTER YOUR PASSWORD, IF NECESSARY)
 (PRESS CONTROL-D OR ENTER "EXIT" TO EXIT THE SHELL)

If you don't use the Startup Item, enter the following command sequence:

 shell> cd /usr/local/mysql
 shell> sudo ./bin/mysqld_safe
 (ENTER YOUR PASSWORD, IF NECESSARY)
 (PRESS CONTROL-Z)
 shell> bg
 (PRESS CONTROL-D OR ENTER "EXIT" TO EXIT THE SHELL)

You can't choose a source/destination server.

If the databases are on the same server you can do this:

If the columns of the table are equal (including order!) then you can do this:

INSERT INTO [destination database].[dbo].[destination table]
SELECT *
FROM [source database].[dbo].[source table]

If you want to do this once you can backup/restore the source database. If you need to do this more often I recommend you start a SSIS project where you define source database (there you can choose any connection on any server) and create a project where you move your data there. See more information here: http://msdn.microsoft.com/en-us/library/ms169917%28v=sql.105%29.aspx

Instead of instantiating the FileUpload in your code behind file, just declare it in your markup file (.aspx file):

<asp:FileUpload ID="fileUpload" runat="server" />

Then you will be able to access all of the properties of the control, such as HasFile.

Here is best solution for this issue: In View add all the ID (Keys). Consider having multiple tables named (First, Second and Third)

@Html.HiddenFor(model=>model.FirstID)
@Html.HiddenFor(model=>model.SecondID)
@Html.HiddenFor(model=>model.Second.SecondID)
@Html.HiddenFor(model=>model.Second.ThirdID)
@Html.HiddenFor(model=>model.Second.Third.ThirdID)

In C# code,

[HttpPost]
public ActionResult Edit(First first)
{
  if (ModelState.Isvalid)
  {
    if (first.FirstID > 0)
    {
      datacontext.Entry(first).State = EntityState.Modified;
      datacontext.Entry(first.Second).State = EntityState.Modified;
      datacontext.Entry(first.Second.Third).State = EntityState.Modified;
    }
    else
    {
      datacontext.First.Add(first);
    }
    datacontext.SaveChanges();
    Return RedirectToAction("Index");
  }

 return View(first);
}

Also, we can use it following ways

To get only first

 $cat_details = DB::table('an_category')->where('slug', 'people')->first();

To get by limit and offset

$top_articles = DB::table('an_pages')->where('status',1)->limit(30)->offset(0)->orderBy('id', 'DESC')->get();
$remaining_articles = DB::table('an_pages')->where('status',1)->limit(30)->offset(30)->orderBy('id', 'DESC')->get();

For SQL Server, you can use tool Import Data from another Database, It's easier to configuration mapping columns.

with open('writing_file.json', 'w') as w:
    with open('reading_file.json', 'r') as r:
        for line in r:
            element = json.loads(line.strip())
            if 'hours' in element:
                del element['hours']
            w.write(json.dumps(element))

this is the method i use..

In case you are looking for Android SDK Manager, you can download it here.

It is important to unzip it as C:/Program Files/Android/. Launch the SDK manager by running C:/Program Files/Android/tools/android.bat administrator.

You can create your own SCSS function for this. Adding the following to your config.rb file.

require 'sass'
require 'cgi'

module Sass::Script::Functions

  def inline_svg_image(path, fill)
    real_path = File.join(Compass.configuration.images_path, path.value)
    svg = data(real_path)
    svg.gsub! '{color}', fill.value
    encoded_svg = CGI::escape(svg).gsub('+', '%20')
    data_url = "url('data:image/svg+xml;charset=utf-8," + encoded_svg + "')"
    Sass::Script::String.new(data_url)
  end

private

  def data(real_path)
    if File.readable?(real_path)
      File.open(real_path, "rb") {|io| io.read}
    else
      raise Compass::Error, "File not found or cannot be read: #{real_path}"
    end
  end

end

Then you can use it in your CSS:

.icon {
  background-image: inline-svg-image('icons/icon.svg', '#555');
}

You will need to edit your SVG files and replace any fill attributes in the markup with fill="{color}"

The icon path is always relative to your images_dir parameter in the same config.rb file.

Similar to some of the other solutions, but this is pretty clean and keeps your SCSS files tidy!

Technical differences are a consequence of the goal of each one (OpenJDK is meant to be the reference implementation, open to the community, while Oracle is meant to be a commercial one)

They both have "almost" the same code of the classes in the Java API; but the code for the virtual machine itself is actually different, and when it comes to libraries, OpenJDK tends to use open libraries while Oracle tends to use closed ones; for instance, the font library.

As simple as:

your_map.begin()->second // value

Disclaimer: I work at BrowserStack. ^{[Confirmed]that whether am allowed to post this (Can I suggest a product of the company am working at?)}

Debug Safari on iOS (not for Chrome as of now, read ahead for more details.)

How this works?

• You need to start a session on any real device (there are emulators but you need to start a session on a real device) on BrowserStack, say iPhone 6S - Safari / Chrome(no devtools for Chrome yet, but it is on our Roadmap)
• Type in the URL
• You can trigger DevTools to inspect the webpage opened on the BrowserStacks remote device. I've shared the screens for the same below.

Using DevTools with Real Phones

Hover over the elements, edit HTML, CSS just like desktop browser devtools work.

Executing JavaScript in real phone using DevTools

Switch to Console tab, execute JavaScript code, check console.log() output and so on...

Network tab, check request headers, response and so on...

Support for DevTools on BrowserStack?

• DevTools are available on :

  • Real Devices - iOS - Safari (DevTools for iOS Chrome is on our Roadmap)
  • Real Devices - Android - Chrome (Only Chrome is available on Android devices for now)

• Client browser needs to be Chrome or Firefox. That means you need to use Chrome or Firefox browser on MacOSX or Windows to use BrowserStack Real Device DevTools.

Note: You need to buy a plan to test on all real devices, as a free user, you'll get couple of Real Android devices (includes tablets) and couple of Real iOS devices (includes tablets). Also, emphasizing on the word Real Devices because they provide emulators as well.

More details on this, please refer to DevTools section on Mobile Features page.

Try the following:

 RewriteEngine On
 RewriteCond %{HTTPS} !=on
 RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R,L]

Also, you can also redirect based on port number, for example:

 RewriteCond %{SERVER_PORT} ^80$
 RewriteRule ^.*$ https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

This will redirect all requests received on port 80 to HTTPS.

if you want to remove pagination and but want ordering of dataTable then add this script at the end of your page!

<script>_x000D_
$(document).ready(function() {        _x000D_
    $('#table_id').DataTable({_x000D_
        "paging":   false,_x000D_
       "info":     false_x000D_
    } );_x000D_
      _x000D_
  } );_x000D_
</script>

Yes the culprit is definitely word-wrapping. When I tested your two programs, NetBeans IDE 8.2 gave me the following result.

1. First Matrix: O and # = 6.03 seconds
2. Second Matrix: O and B = 50.97 seconds

Looking at your code closely you have used a line break at the end of first loop. But you didn't use any line break in second loop. So you are going to print a word with 1000 characters in the second loop. That causes a word-wrapping problem. If we use a non-word character " " after B, it takes only 5.35 seconds to compile the program. And If we use a line break in the second loop after passing 100 values or 50 values, it takes only 8.56 seconds and 7.05 seconds respectively.

Random r = new Random();
for (int i = 0; i < 1000; i++) {
    for (int j = 0; j < 1000; j++) {
        if(r.nextInt(4) == 0) {
            System.out.print("O");
        } else {
            System.out.print("B");
        }
        if(j%100==0){               //Adding a line break in second loop      
            System.out.println();
        }                    
    }
    System.out.println("");                
}

Another advice is that to change settings of NetBeans IDE. First of all, go to NetBeans Tools and click Options. After that click Editor and go to Formatting tab. Then select Anywhere in Line Wrap Option. It will take almost 6.24% less time to compile the program.

$sth = mysqli_query($conn, "SELECT ...");
$rows = array();
while($r = mysqli_fetch_assoc($sth)) {
    $rows[] = $r;
}
print json_encode($rows);

The function json_encode needs PHP >= 5.2 and the php-json package - as mentioned here

NOTE: mysql is deprecated as of PHP 5.5.0, use mysqli extension instead http://php.net/manual/en/migration55.deprecated.php.

If you're willing and able to employ a little jquery, you can simply do this:

$('.someDiv').css([".radius", ".opacity"]);

If you have a javascript that already processes the page or you can enclose it somewhere in <script> tags. If so, wrap the above in the document ready function:

$(document).ready( function() {
  $('.someDiv').css([".radius", ".opacity"]);
}

I recently came across this while updating a wordpress plugin. The them has been changed which used a lot of "!important" directives across the css. I had to use jquery to force my styles because of the genius decision to declare !important on several tags.

Try the following line:

while read line1; do read line2; echo "$line1 $line2"; done <old.txt>new_file

Put delimiter in-between

"$line1 $line2";

e.g. if the delimiter is |, then:

"$line1|$line2";

I solved this issue by granting the service-account the Service Account User role in addition to the Cloud Datastore User role in the IAM settings of GCP.

Install from linux terminal

sudo apt-get install php7.0-dev   #For `php` version 7.0

Named parameters are not supported by JPA in native queries, only for JPQL. You must use positional parameters.

Named parameters follow the rules for identifiers defined in Section 4.4.1. The use of named parameters applies to the Java Persistence query language, and is not defined for native queries. Only positional parameter binding may be portably used for native queries.

So, use this

Query q = em.createNativeQuery("SELECT count(*) FROM mytable where username = ?1");
q.setParameter(1, "test");

While JPA specification doesn't support named parameters in native queries, some JPA implementations (like Hibernate) may support it

Native SQL queries support positional as well as named parameters

However, this couples your application to specific JPA implementation, and thus makes it unportable.

To enable the Windows Authentication on IIS7 on Windows 7 machine:

• Select "Turn Windows Features on or off" from left side.

• Expand Internet Information Services >> World Wide Web Services >> Security

• Select Windows Authentication and click OK.

• Reset the IIS and Check in IIS now for windows authentication.

GZip Compression can be enabled directly through IIS.

First, open up IIS,

go to the website you are hoping to tweak and hit the Compression page. If Gzip is not installed, you will see something like the following:

“The dynamic content compression module is not installed.” We should fix this. So we go to the “Turn Windows features on or off” and select “Dynamic Content Compression” and click the OK button.

Now if we go back to IIS, we should see that the compression page has changed. At this point we need to make sure the dynamic compression checkbox is checked and we’re good to go. Compression is enabled and our dynamic content will be Gzipped.

Testing - Check if GZIP Compression is Enabled

To test whether compression is working or not, use the developer tools in Chrome or Firebug for Firefox and ensure the HTTP response header is set:

Content-Encoding: gzip

Null means nothing. Its just a literal. Null is the value of reference variable. But empty string is blank.It gives the length=0. Empty string is a blank value,means the string does not have any thing.

When I was facing this issue I used to install OpenCV in pycharm installed package panel where we can find under the settings tab. Search "OpenCV-python" and install it in the installed package panel of right interpreter.

from IPython.utils.io import Tee
from contextlib import closing

print('This is not in the output file.')        

with closing(Tee("outputfile.log", "w", channel="stdout")) as outputstream:
    print('This is written to the output file and the console.')
    # raise Exception('The file "outputfile.log" is closed anyway.')
print('This is not written to the output file.')   

# Output on console:
# This is not in the output file.
# This is written to the output file and the console.
# This is not written to the output file.

# Content of file outputfile.txt:
# This is written to the output file and the console.

The Tee class in IPython.utils.io does what you want, but it lacks the __enter__ and __exit__ methods needed to call it in the with-statement. Those are added by contextlib.closing.

This function overwrites an existing argument

function addToURL( $key, $value, $url) {
    $info = parse_url( $url );
    parse_str( $info['query'], $query );
    return $info['scheme'] . '://' . $info['host'] . $info['path'] . '?' . http_build_query( $query ? array_merge( $query, array($key => $value ) ) : array( $key => $value ) );
}

I have to add an important difference between using node's build in cluster mode VS a process manager like PM2's cluster mode.

PM2 allows zero down time reloads when you are running.

pm2 start app.js -i 2 --wait-ready

In your codes add the following

process.send('ready');

When you call pm2 reload app after code updates, PM2 will reload the first instance of the app, wait for the 'ready' call, then it move on to reloads the next instance, ensuring you always have an app active to respond to requests.

While if you use nodejs' cluster, there will be down time when you restart and waiting for server to be ready.

In Style.xml pre-define the style:

<style name="largeText">
    <item name="android:textAppearance">@android:style/TextAppearance.Large.Inverse</item>
    <item name="android:textStyle">bold</item>
</style>

in code:

text.setTextAppearance(context, R.style.largeText);

Check out the ColumnComparator. It is basically the same solution as proposed by Costi, but it also supports sorting on columns in a List and has a few more sort properties.

Unformatted and formatted:

$price = $product->getPrice();
$formatted = Mage::helper('core')->currency($price, true, false);

Or use:

Mage::helper('core')->formatPrice($price, true);

If you're using AD you can use serverless binding to locate a domain controller for the default domain, then use LDAP://rootDSE to get information about the directory server, as described in the linked article.

{
    switch( $test )
    {
        case 1:
            // do this
            break;
        case 2:
            // do this
            break;
        default:
            // do this
            break;
    }
}

In SQLite you should do this:

SELECT * 
FROM leftTable lt 
LEFT JOIN rightTable rt ON lt.id = rt.lrid 
UNION
SELECT lt.*, rl.*  -- To match column set
FROM rightTable rt 
LEFT JOIN  leftTable lt ON lt.id = rt.lrid

In my case, this error happen when i call a page by using the following code

 this.navCtrl.push("Login"); // Bug

I just removed the quotes like the following and also imported that page on the top of the file which i used call the Login page

I can't explain the difference at this time since i'm a beginner level developer

It's not because of a different code, but because of caching: RAM is slower than the CPU registers and a cache memory is inside the CPU to avoid to write the RAM every time a variable is changing. But the cache is not big as the RAM is, hence, it maps only a fraction of it.

The first code modifies distant memory addresses alternating them at each loop, thus requiring continuously to invalidate the cache.

The second code don't alternate: it just flow on adjacent addresses twice. This makes all the job to be completed in the cache, invalidating it only after the second loop starts.

If you're using gnu sed then you can use \x0A for newline:

sed 's/:/\x0A/g' ~/Desktop/myfile.txt

Piece of cake:

arr := []byte("That's all folks!!")

I take it from your question that your hover effect changes the content of your page. In that case, my advice is to:

• Add hover effects on touchstart and mouseenter.
• Remove hover effects on mouseleave, touchmove and click.

Alternatively, you can edit your page that there is no content change.

Background

In order to simulate a mouse, browsers such as Webkit mobile fire the following events if a user touches and releases a finger on touch screen (like iPad) (source: Touch And Mouse on html5rocks.com):

1. touchstart
2. touchmove
3. touchend
4. 300ms delay, where the browser makes sure this is a single tap, not a double tap
5. mouseover
6. mouseenter
   • Note: If a mouseover, mouseenter or mousemove event changes the page content, the following events are never fired.
7. mousemove
8. mousedown
9. mouseup
10. click

It does not seem possible to simply tell the webbrowser to skip the mouse events.

What's worse, if a mouseover event changes the page content, the click event is never fired, as explained on Safari Web Content Guide - Handling Events, in particular figure 6.4 in One-Finger Events. What exactly a "content change" is, will depend on browser and version. I've found that for iOS 7.0, a change in background color is not (or no longer?) a content change.

Solution Explained

To recap:

• Add hover effects on touchstart and mouseenter.
• Remove hover effects on mouseleave, touchmove and click.

Note that there is no action on touchend!

This clearly works for mouse events: mouseenter and mouseleave (slightly improved versions of mouseover and mouseout) are fired, and add and remove the hover.

If the user actually clicks a link, the hover effect is also removed. This ensure that it is removed if the user presses the back button in the web browser.

This also works for touch events: on touchstart the hover effect is added. It is '''not''' removed on touchend. It is added again on mouseenter, and since this causes no content changes (it was already added), the click event is also fired, and the link is followed without the need for the user to click again!

The 300ms delay that a browser has between a touchstart event and click is actually put in good use because the hover effect will be shown during this short time.

If the user decides to cancel the click, a move of the finger will do so just as normal. Normally, this is a problem since no mouseleave event is fired, and the hover effect remains in place. Thankfully, this can easily be fixed by removing the hover effect on touchmove.

That's it!

Note that it is possible to remove the 300ms delay, for example using the FastClick library, but this is out of scope for this question.

Alternative Solutions

I've found the following problems with the following alternatives:

• browser detection: Extremely prone to errors. Assumes that a device has either mouse or touch, while a combination of both will become more and more common when touch displays prolifirate.
• CSS media detection: The only CSS-only solution I'm aware of. Still prone to errors, and still assumes that a device has either mouse or touch, while both are possible.
• Emulate the click event in touchend: This will incorrectly follow the link, even if the user only wanted to scroll or zoom, without the intention of actually clicking the link.
• Use a variable to suppress mouse events: This set a variable in touchend that is used as a if-condition in subsequent mouse events to prevents state changes at that point in time. The variable is reset in the click event. See Walter Roman's answer on this page. This is a decent solution if you really don't want a hover effect on touch interfaces. Unfortunately, this does not work if a touchend is fired for another reason and no click event is fired (e.g. the user scrolled or zoomed), and is subsequently trying to following the link with a mouse (i.e on a device with both mouse and touch interface).

I was facing the same problem, without using scale_y_continuous nor coord_cartesian.

The conflict was coming from the x axis, where I defined limits = c(1, 30). It seems such limits do not provide enough space if you want to "dodge" your bars, so R still throws the error

Removed 8 rows containing missing values (geom_bar)

Adjusting the limits of the x axis to limits = c(0, 31) solved the problem.

In conclusion, even if you are not putting limits to your y axis, check out your x axis' behavior to ensure you have enough space

Read the FAQ! Holding C++ data in C can be risky.

In C++, a pointer to an object can be converted to void * without any casts. But it's not true the other way round. You'd need a static_cast to get the original pointer back.

All you need is -l and --block-size flags

Size of all files and directories under working directory (in MBs)

ls -l --block-size=M

Size of all files and directories under working directory (in GBs)

ls -l --block-size=G

Size of a specific file or directory

ls -l --block-size=M my_file.txt
ls -l --block-size=M my_dir/

ls --help

-l use a long listing format

--block-size=SIZE: scale sizes by SIZE before printing them; e.g., '--block-size=M' prints sizes in units of 1,048,576 bytes; see SIZE format below

SIZE is an integer and optional unit (example: 10M is 10*1024*1024). Units are K, M, G, T, P, E, Z, Y (powers of 1024) or KB, MB, ... (powers of 1000).

In IntelliJ IDEA this happened to me when I imported a project that had been working fine and running with Java 1.7. I apparently hadn't notified IntelliJ that java 1.7 had been installed on my machine, and it wasn't finding my $JAVA_HOME.

On a Mac, this is resolved by:

Right clicking on the module | Module Settings | Project

and adding the 1.7 SDK by selecting "New" in the Project SDK.

Then go to the main IntelliJ IDEA menu | Preferences | Maven | Runner

and select the correct JRE. In my case it updated correctly Use Project SDK, which was now 1.7.

As said before, switch can be used only with integer values. So, you just need to convert your "case" values to integer. You can achieve it by using constexpr from c++11, thus some calls of constexpr functions can be calculated in compile time.

something like that...

switch (str2int(s))
{
  case str2int("Value1"):
    break;
  case str2int("Value2"):
    break;
}

where str2int is like (implementation from here):

constexpr unsigned int str2int(const char* str, int h = 0)
{
    return !str[h] ? 5381 : (str2int(str, h+1) * 33) ^ str[h];
}

Another example, the next function can be calculated in compile time:

constexpr int factorial(int n)
{
    return n <= 1 ? 1 : (n * factorial(n-1));
}  

int f5{factorial(5)};
// Compiler will run factorial(5) 
// and f5 will be initialized by this value.

A different perspective to the same problem away from Javascript and using php:

<a data-toggle="modal" href="#myModal">LINK</a>

<div class="modal fade" tabindex="-1" aria-labelledby="gridSystemModalLabel" id="myModal" role="dialog" style="max-width: 90%;">
    <div class="modal-dialog" style="text-align: left;">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <h4 class="modal-title">Title</h4>
            </div>
            <div class="modal-body">
                <?php include( 'remotefile.php'); ?>
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            </div>
        </div>
    </div>
</div>

and put in the remote.php file your basic html source.

As a variant in the ComboBox SelectionChanged event handler:

private void ComboBoxName_SelectionChanged(object send ...
{
    string s = ComboBoxName.Items.GetItemAt(ComboBoxName.SelectedIndex).ToString();
}

You need to use Concat operation

Let's add pcntl_signal and pcntl_alarm to the list.

With the help of those functions you can work around any set_time_limit restriction created int the php.ini or in the script.

This script for example will run for 10 seconds despite of set_time_limit(1);

(Credit goes to Sebastian Bergmanns tweet and gist:

<?php
declare(ticks = 1);

set_time_limit(1);

function foo() {
    for (;;) {}
}

class Invoker_TimeoutException extends RuntimeException {}

class Invoker
{
    public function invoke($callable, $timeout)
    {
        pcntl_signal(SIGALRM, function() { throw new Invoker_TimeoutException; }, TRUE);
        pcntl_alarm($timeout);
        call_user_func($callable);
    }
}

try {
    $invoker = new Invoker;
    $invoker->invoke('foo', 1);
} catch (Exception $e) {
    sleep(10);
    echo "Still running despite of the timelimit";
}

Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:

<script type="text/javascript">   $(function() { //jQuery trick to say after all the HTML is parsed.     $("input[type=radio]").click(function() {       var total = 0;       $("input[type=radio]:checked").each(function() {         total += parseFloat($(this).val());       });        $("#totalSum").val(total);     });   }); </script> 

EDIT: This code works for me

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body>   <strong>Choose a base package:</strong>   <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942   <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313   <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829   <strong>Choose an add on:</strong>   <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0   <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146)   <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455)   <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764)   <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073)   <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382)   <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691)   <strong>Your total is:</strong>   <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" />   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>   <script type="text/javascript">       $("input[type=radio]").click(function() {         var total = 0;         $("input[type=radio]:checked").each(function() {           total += parseFloat($(this).val());         });          $("#totalSum").val(total);       });     </script> </body> </html>

I had a similar problem recently and found out, that client_max_body_size 0; can solve such an issue. This will set client_max_body_size to no limit. But the best practice is to improve your code, so there is no need to increase this limit.

if val is not None:
    # ...

is the Pythonic idiom for testing that a variable is not set to None. This idiom has particular uses in the case of declaring keyword functions with default parameters. is tests identity in Python. Because there is one and only one instance of None present in a running Python script/program, is is the optimal test for this. As Johnsyweb points out, this is discussed in PEP 8 under "Programming Recommendations".

As for why this is preferred to

if not (val is None):
    # ...

this is simply part of the Zen of Python: "Readability counts." Good Python is often close to good pseudocode.

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

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

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

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

Olof's answer is good, but it needs one more thing before it's perfect. In the comments below his answer, dacwe (correctly) points out that his implementation violates the Compare/Equals contract for Sets. If you try to call contains or remove on an entry that's clearly in the set, the set won't recognize it because of the code that allows entries with equal values to be placed in the set. So, in order to fix this, we need to test for equality between the keys:

static <K,V extends Comparable<? super V>> SortedSet<Map.Entry<K,V>> entriesSortedByValues(Map<K,V> map) {
    SortedSet<Map.Entry<K,V>> sortedEntries = new TreeSet<Map.Entry<K,V>>(
        new Comparator<Map.Entry<K,V>>() {
            @Override public int compare(Map.Entry<K,V> e1, Map.Entry<K,V> e2) {
                int res = e1.getValue().compareTo(e2.getValue());
                if (e1.getKey().equals(e2.getKey())) {
                    return res; // Code will now handle equality properly
                } else {
                    return res != 0 ? res : 1; // While still adding all entries
                }
            }
        }
    );
    sortedEntries.addAll(map.entrySet());
    return sortedEntries;
}

"Note that the ordering maintained by a sorted set (whether or not an explicit comparator is provided) must be consistent with equals if the sorted set is to correctly implement the Set interface... the Set interface is defined in terms of the equals operation, but a sorted set performs all element comparisons using its compareTo (or compare) method, so two elements that are deemed equal by this method are, from the standpoint of the sorted set, equal." (http://docs.oracle.com/javase/6/docs/api/java/util/SortedSet.html)

Since we originally overlooked equality in order to force the set to add equal valued entries, now we have to test for equality in the keys in order for the set to actually return the entry you're looking for. This is kinda messy and definitely not how sets were intended to be used - but it works.

typeof is an operator to obtain a type known at compile-time (or at least a generic type parameter). The operand of typeof is always the name of a type or type parameter - never an expression with a value (e.g. a variable). See the C# language specification for more details.

GetType() is a method you call on individual objects, to get the execution-time type of the object.

Note that unless you only want exactly instances of TextBox (rather than instances of subclasses) you'd usually use:

if (myControl is TextBox)
{
    // Whatever
}

Or

TextBox tb = myControl as TextBox;
if (tb != null)
{
    // Use tb
}

In the launcher script you can force it, it permits to keep the same script and same launcher for both architecture

:: For 32 bits architecture, this line is sufficent (32bits is the only cscript available)
set CSCRIPT="cscript.exe"
:: Detect windows 64bits and use the expected cscript (SysWOW64 contains 32bits executable)
if exist "C:\Windows\SysWOW64\cscript.exe" set CSCRIPT="C:\Windows\SysWOW64\cscript.exe"

You can test it out in this jsbin: http://jsbin.com/uxecel/4/edit

While you can store files in this fashion, it has significant tradeoffs:

• Most DBs are not optimized for giant quantities of binary data, and query performance often degrades dramatically as the table bloats, even with indexes. (SQL Server 2008, with the FILESTREAM column type, is the exception to the rule.)
• DB backup/replication becomes extremely slow.
• It's a lot easier to handle a corrupted drive with 2 million images -- just replace the disk on the RAID -- than a DB table that becomes corrupted.
• If you accidentally delete a dozen images on a filesystem, your operations guys can replace them pretty easily from a backup, and since the table index is tiny by comparison, it can be restored quickly. If you accidentally delete a dozen images in a giant database table, you have a long and painful wait to restore the DB from backup, paralyzing your entire system in the meantime.

These are just some of the drawbacks I can come up with off the top of my head. For tiny projects it may be worth storing files in this fashion, but if you're designing enterprise-grade software I would strongly recommend against it.

ADT v15 for Eclipse let you specify an application name (which is actually the package value in your androidmanifest.xml).

I love being able to filter by app, but the new logcat has a bug with the autoscroll. When you scroll up a little to look at previous logs, it automatically scrolls back to the bottom in a couple seconds. It seems scrolling 1/2 way up the log does keep it from jumping back to the bottom, but that's often useless.

EDIT: I tried specifying an app filter from the command-line -- but no luck. If someone figures this out OR how to stop the autoscroll, please let me know.

I recommend using ECMAScript 6 spread operator, which will Bind trailing parameters to an array. With this solution you don't need to touch the arguments object and your code will be simplified. The downside of this solution is that it does not work across most browsers, so instead you will have to use a JS compiler such as Babel. Under the hood Babel transforms arguments into a Array with a for loop.

function sortArgs(...args) {
  return args.sort();
}

If you can not use a ECMAScript 6, I recommend looking at some of the other answers such as @Jonathan Fingland

function sortArgs() {
    var args = Array.prototype.slice.call(arguments);
    return args.sort();
}

Useful for the case where you want to make sure 2 numbers are the same 'up to precision', no need to specify the tolerance:

• Find minimum precision of the 2 numbers

• Round both of them to minimum precision and compare

def isclose(a,b):                                       
    astr=str(a)                                         
    aprec=len(astr.split('.')[1]) if '.' in astr else 0 
    bstr=str(b)                                         
    bprec=len(bstr.split('.')[1]) if '.' in bstr else 0 
    prec=min(aprec,bprec)                                      
    return round(a,prec)==round(b,prec)                               

As written, only works for numbers without the 'e' in their string representation ( meaning 0.9999999999995e-4 < number <= 0.9999999999995e11 )

Example:

>>> isclose(10.0,10.049)
True
>>> isclose(10.0,10.05)
False

You can check Observable represented by Rxjs, lets you return more than one value.

Yes you only need $() when you're using jQuery. If you want jQuery's help to do DOM things just keep this in mind.

$(this)[0] === this

Basically every time you get a set of elements back jQuery turns it into a jQuery object. If you know you only have one result, it's going to be in the first element.

$("#myDiv")[0] === document.getElementById("myDiv");

And so on...

You can use this function to disable the form:

function disableForm(formID){
  $('#' + formID).children(':input').attr('disabled', 'disabled');
}

See the working demo here

Note that it uses jQuery.

I got this error in an Ubuntu Docker container. I believe the cause was that the container was missing CA certs. To fix it, I had to run:

To upload image with form fields

let requestoptions = new RequestOptions({

    });



let formData: FormData = new FormData();
if (picture != null || picture != undefined) {
  formData.append('files', picture, picture.name);
}
 formData.append("article",JSON.stringify(article));

return this.http.post("url",formData,requestoptions)
  .map((response: Response) => response.json() as ArticleModel);

    Article article = null;
    try

        if (httpRequest.Files.Count == 1)
        {
            postedFile = httpRequest.Files[0];
            var filePath = HttpContext.Current.Server.MapPath("~/" + postedFile.FileName);
            postedFile.SaveAs(filePath);
        }
        var json = httpRequest.Form["article"];
         article = JsonConvert.DeserializeObject <Article>(json);

        if (!ModelState.IsValid)
        {
            return BadRequest(ModelState);
        }

        article.CreatedDate = DateTime.Now;
        article.CreatedBy = "Abbas";

        db.articles.Add(article);
        await db.SaveChangesAsync();
    }

In SQLServer Management Studio:

Tools -> Options -> Designers -> Table and Database Designers

Unselect Prevent saving changes that require table re-creation.

Now you can reorder the table.

I forgot to mention. This should also accept whitespace.

You could use:

/^[-@.\/#&+\w\s]*$/

Note how this makes use of the character classes \w and \s.

EDIT:- Added \ to escape /

Why don't you try to grep the return of your command ? Something like :

adb devices -l | grep 123abc12

It should return only the line you want to.

Please note that this answer was written for Mac OS El Capitan. For newer versions, beware that it may no longer apply. In particular, the legacy option is quite possibly deprecated.

There are two solutions to the problem, and they are both mentioned in other answers to this question and to How to get gdb to work using macports under OSX 10.11 El Capitan?, but to clear up some confusion here is my summary (as an answer since it got a bit long for a comment):

Which alternative is more secure I guess boils down to the choice between 1) trusting self-signed certificates and 2) giving users more privileges.

Alternative 1: signing the binary

If the signature alternative is used, disabling SIP to add the -p option to taskgated is not required.

However, note that with this alternative, debugging is only allowed for users in the _developer group.

Using codesign to sign using a cert named gdb-cert:

codesign -s gdb-cert /opt/local/bin/ggdb

(using the MacPorts standard path, adopt as necessary)

For detailed code-signing recipes (incl cert creation), see : https://gcc.gnu.org/onlinedocs/gcc-4.8.1/gnat_ugn_unw/Codesigning-the-Debugger.html or https://sourceware.org/gdb/wiki/BuildingOnDarwin

Note that you need to restart the keychain application and the taskgated service during and after the process (the easiest way is to reboot).

Alternative 2: use the legacy option for taskgated

As per the answer by @user14241, disabling SIP and adding the -p option to taskgated is an option. Note that if using this option, signing the binary is not needed, and it also bypasses the dialog for authenticating as a member of the Developer Tools group (_developer).

After adding the -p option (allow groups procmod and procview) to taskgated you also need to add the users that should be allowed to use gdb to the procmod group.

The recipe is:

1. restart in recovery mode, open a terminal and run csrutil disable

2. restart machine and edit /System/Library/LaunchDaemons/com.apple.taskgated.plist, adding the -p opion:

   <array>
       <string>/usr/libexec/taskgated</string>
       <string>-sp</string>
   </array>
   

3. restart in recovery mode to reenable SIP (csrutil enable)

4. restart machine and add user USERNAME to the group procmod:

   sudo dseditgroup -o edit -a USERNAME -t user procmod

   An alternative that does not involve adding users to groups is to make the executable setgid procmod, as that also makes procmod the effective group id of any user executing the setgid binary (suggested in https://apple.stackexchange.com/a/112132)

   sudo chgrp procmod /path/to/gdb
   sudo chmod g+s /path/to/gdb

Just open MySQL Workbench and choose [Instance] Startup/Shutdown and click on start server. It worked for me

This (mysql_connect, mysql_...) extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should be used.
(ref: http://php.net/manual/en/function.mysql-connect.php)

• Object Oriented:

  $mysqli = new mysqli("host", "user", "password");
  $mysqli->select_db("db");
  

• Procedural:

  $link = mysqli_connect("host","user","password") or die(mysqli_error($link)); 
  mysqli_select_db($link, "db");
  

If you want 8 bit representation of characters that used in many encoding, this may help you.

You must change variable targetEncoding to whatever encoding you want.

Encoding targetEncoding = Encoding.GetEncoding(874); // Your target encoding
Encoding utf8 = Encoding.UTF8;

var stringBytes = utf8.GetBytes(Name);
var stringTargetBytes = Encoding.Convert(utf8, targetEncoding, stringBytes);
var ascii8BitRepresentAsCsString = Encoding.GetEncoding("Latin1").GetString(stringTargetBytes);

I found another answer which may be correct as accepted answer.

for root, dirs, files in os.walk(input_path):    
for name in files:
    if os.path.splitext(name)[1] == '.TXT' or os.path.splitext(name)[1] == '.txt':
        datafiles.append(os.path.join(root,name)) 


print len(files) 

The same for me. My problem appeared because i forgot that my base model class already has property with the name which was defined in the view.

public class CTX : DbContext {  // context with domain models
    public DbSet<Products> Products { get; set; }  // "Products" is the source property
    public CTX() : base("Entities") {}
}

public class BaseModel : CTX { ... }
public class ProductModel : BaseModel { ... }
public class OrderIndexModel : OrderModel  { ... }

... and controller processing model :

[HttpPost]
[ValidateInput(false)]
public ActionResult Index(OrderIndexModel order) { ... }

Nothing special, right? But then i define the view ...

<div class="dataItem">
    <%=Html.Label("Products")%>
    <%=Html.Hidden("Products", Model.index)%>   // I FORGOT THAT I ALREADY HAVE PROPERTY CALLED "Products"
    <%=Html.DropDownList("ProductList", Model.products)%>
    <%=Html.ActionLink("Delete", "D")%>
</div>

... which causes "Parameterless constructor" error on POST request.

Hope that helps.

MiniDLNA uses inotify, which is a functionality within the Linux kernel, used to discover changes in specific files and directories on the file system. To get it to work, you need inotify support enabled in your kernel.

The notify_interval (notice the lack of a leading 'i'), as far as I can tell, is only used if you have inotify disabled. To use the notify_interval (ie. get the server to 'poll' the file system for changes instead of automatically being notified of them), you have to disable the inotify functionality.

This is how it looks in my /etc/minidlna.conf:

# set this to no to disable inotify monitoring to automatically discover new files
# note: the default is yes
inotify=yes

Make sure that inotify is enabled in your kernel.

If it's not enabled, and you don't want to enable it, a forced rescan is the way to force MiniDLNA to re-scan the drive.

Here is another version for Wordpress, original one did not work as intended.

# BEGIN WordPress
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteRule ^index\.php$ - [END]
    RewriteCond $1 ^(index\.php)?$ [OR]
    RewriteCond $1 \.(gif|jpg|png|ico|css|js)$ [NC,OR]
    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^(.*)$ - [END]
    RewriteRule ^ /index.php [L]
</IfModule>
# END WordPress

Reference from this Github repository, modified a bit. After excessive testing this rule does not solve all problems. We have a Wordpress webshop, which has 40 plugins and somewhere is there a rewrite clash. I sincerely hope next version of Wordpress has no URL rewrites.

RewriteRule ^index\.php$ - [L]

The ^ signifies start of the string, \ escapes . or it would mean any character, and $ signifies end of the string.

^index\.php$ if http(s)://hostname/index.php - do nothing [END] flag can be used to terminate not only the current round of rewrite processing but prevent any subsequent rewrite processing.

RewriteCond $1 ^(index\.php)?$ [OR]

In RewriteCond using $1 as a test string references to captured contents of everything from the start to the end of the url http(s)://hostname/bla/bla.php. If used in substitution or condition it references to captured backreference. RewriteRule (bla)/(ble\.php)$ - for http(s)://hostname/bla/ble.php captures bla into $1 and ble.php into $2. Multiple capture groups can be accessed via $3..N.

( ) groups several characters into single unit, ? forces the match optional. [OR] flag allows you to combine rewrite conditions with a logical OR relationship as opposed to the default AND.

In short, if bla/bla.php contains index.php OR next condition

RewriteCond $1 \.(gif|jpg|png|ico|css|js)$ [NC,OR]

( ) groups several characters into single unit, | separates characters to subgroups and conditions them if any one of. [NC] flag causes the RewriteRule to be matched in case-insensitive manner.

In short, if bla/bla.php ends with any of the filetypes OR next condition

RewriteCond %{REQUEST_FILENAME} -f [OR]

Server-Variables are variables of the form %{ NAME_OF_VARIABLE } where NAME_OF_VARIABLE can be a string taken from the following list:

%{REQUEST_FILENAME} is full local filesystem path to the file or script matching the request, if this has already been determined by the server at the time REQUEST_FILENAME is referenced. Otherwise, such as when used in virtual host context, the same value as REQUEST_URI. Depending on the value of AcceptPathInfo, the server may have only used some leading components of the REQUEST_URI to map the request to a file.

-f check for regular file. Treats the test string as pathname and tests whether or not it exists.

In short, if bla/bla.php is a file OR next condition

RewriteCond %{REQUEST_FILENAME} -d

-d check for directory. Treats the test string as a pathname and tests whether or not it exists.

In short, if bla/bla.php is a directory

RewriteRule ^(.*)$ - [END] not as in Github [S=1]

This statement is only executed when one of the condition returned true.

. match any character * zero or more times.

The [S] flag is used to skip rules that you don't want to run. The syntax of the skip flag is [S=N], where N signifies the number of rules to skip (provided the RewriteRule matches). This can be thought of as a goto statement in your rewrite ruleset. In the following example, we only want to run the RewriteRule if the requested URI doesn't correspond with an actual file.

In short, do nothing

RewriteRule ^ /index.php [L]

The [L] flag causes mod_rewrite to stop processing the rule set. In most contexts, this means that if the rule matches, no further rules will be processed. This corresponds to the last command in Perl, or the break command in C. Use this flag to indicate that the current rule should be applied immediately without considering further rules.

In short, rewrite every path as http(s)://hostname/index.php

I fetched this little doc together from apaches.org documentation. Links below.

• Apache mod_rewrite Introduction
• Apache Module mod_rewrite
• Apache mod_rewrite RewriteRule Flags

INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas.

Example:

INSERT INTO tbl_name
    (a,b,c)
VALUES
    (1,2,3),
    (4,5,6),
    (7,8,9);

Source

"docker build -f Dockerfile -t SpringBoot-Docker ." As in the above commend, we are creating an image file for docker container. commend says create image use file(-f refer to docker file) and -t for the target of the image file we are going to push to docker. the "." represents the current directory

solution for the above problem: provide target image name in lowercase

For those using yarn.

I tried using npm shrinkwrap until I discovered the yarn cli ignored my npm-shrinkwrap.json file.

Yarn has https://yarnpkg.com/lang/en/docs/selective-version-resolutions/ for this. Neat.

Notwithstanding the other answers recommending List<T>, you'll want to use arrays when handling:

• image bitmap data
• other low-level data-structures (i.e. network protocols)

MochiKit has a testing framework called SimpleTest that seems to have caught on. Here's a blog post from the original author.

There are three options.

• You can use a native managed SFTP service recently added by Amazon (which is easier to set up).
• Or you can mount the bucket to a file system on a Linux server and access the files using the SFTP as any other files on the server (which gives you greater control).
• Or you can just use a (GUI) client that natively supports S3 protocol (what is free).

Managed SFTP Service

• In your Amazon AWS Console, go to AWS Transfer for SFTP and create a new server.

• In SFTP server page, add a new SFTP user (or users).

  • Permissions of users are governed by an associated AWS role in IAM service (for a quick start, you can use AmazonS3FullAccess policy).

  • The role must have a trust relationship to transfer.amazonaws.com.

For details, see my guide Setting up an SFTP access to Amazon S3.

Mounting Bucket to Linux Server

Just mount the bucket using s3fs file system (or similar) to a Linux server (e.g. Amazon EC2) and use the server's built-in SFTP server to access the bucket.

• Install the s3fs
• Add your security credentials in a form access-key-id:secret-access-key to /etc/passwd-s3fs

• Add a bucket mounting entry to fstab:

  <bucket> /mnt/<bucket> fuse.s3fs rw,nosuid,nodev,allow_other 0 0
  

For details, see my guide Setting up an SFTP access to Amazon S3.

Use S3 Client

Or use any free "FTP/SFTP client", that's also an "S3 client", and you do not have setup anything on server-side. For example, my WinSCP or Cyberduck.

WinSCP has even scripting and .NET/PowerShell interface, if you need to automate the transfers.

This question seems to have been put to rest, but in my quest for a solution that I could more easily understand (and written in Swift), I arrived at this (also posted to: How to crop the UIImage?)

I wanted to be able to crop from a region based on an aspect ratio, and scale to a size based on a outer bounding extent. Here is my variation:

import AVFoundation
import ImageIO

class Image {

    class func crop(image:UIImage, crop source:CGRect, aspect:CGSize, outputExtent:CGSize) -> UIImage {

        let sourceRect = AVMakeRectWithAspectRatioInsideRect(aspect, source)
        let targetRect = AVMakeRectWithAspectRatioInsideRect(aspect, CGRect(origin: CGPointZero, size: outputExtent))

        let opaque = true, deviceScale:CGFloat = 0.0 // use scale of device's main screen
        UIGraphicsBeginImageContextWithOptions(targetRect.size, opaque, deviceScale)

        let scale = max(
            targetRect.size.width / sourceRect.size.width,
            targetRect.size.height / sourceRect.size.height)

        let drawRect = CGRect(origin: -sourceRect.origin * scale, size: image.size * scale)
        image.drawInRect(drawRect)

        let scaledImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        return scaledImage
    }
}

There are a couple things that I found confusing, the separate concerns of cropping and resizing. Cropping is handled with the origin of the rect that you pass to drawInRect, and scaling is handled by the size portion. In my case, I needed to relate the size of the cropping rect on the source, to my output rect of the same aspect ratio. The scale factor is then output / input, and this needs to be applied to the drawRect (passed to drawInRect).

One caveat is that this approach effectively assumes that the image you are drawing is larger than the image context. I have not tested this, but I think you can use this code to handle cropping / zooming, but explicitly defining the scale parameter to be the aforementioned scale parameter. By default, UIKit applies a multiplier based on the screen resolution.

Finally, it should be noted that this UIKit approach is higher level than CoreGraphics / Quartz and Core Image approaches, and seems to handle image orientation issues. It is also worth mentioning that it is pretty fast, second to ImageIO, according to this post here: http://nshipster.com/image-resizing/

You can't call alpha's alphaMethod1() by using beta's object But you have two solutions:

solution 1: call alpha's alphaMethod1() from beta's alphaMethod1()

class Beta extends Alpha
{
  public void alphaMethod1()
  {
    super.alphaMethod1();
  }
}

or from any other method of Beta like:

class Beta extends Alpha
{
  public void foo()
  {
     super.alphaMethod1();
  }
}

class Test extends Beta 
{
   public static void main(String[] args)
   {
      Beta beta = new Beta();
      beta.foo();
   }
}

solution 2: create alpha's object and call alpha's alphaMethod1()

class Test extends Beta
{
   public static void main(String[] args)
   {
      Alpha alpha = new Alpha();
      alpha.alphaMethod1();
   }
}

While File.ReadAllLines() is one of the simplest ways to read a file, it is also one of the slowest.

If you're just wanting to read lines in a file without doing much, according to these benchmarks, the fastest way to read a file is the age old method of:

using (StreamReader sr = File.OpenText(fileName))
{
        string s = String.Empty;
        while ((s = sr.ReadLine()) != null)
        {
               //do minimal amount of work here
        }
}

However, if you have to do a lot with each line, then this article concludes that the best way is the following (and it's faster to pre-allocate a string[] if you know how many lines you're going to read) :

AllLines = new string[MAX]; //only allocate memory here

using (StreamReader sr = File.OpenText(fileName))
{
        int x = 0;
        while (!sr.EndOfStream)
        {
               AllLines[x] = sr.ReadLine();
               x += 1;
        }
} //Finished. Close the file

//Now parallel process each line in the file
Parallel.For(0, AllLines.Length, x =>
{
    DoYourStuff(AllLines[x]); //do your work here
});

Try Wireshark:

Wireshark is the world's foremost network protocol analyzer, and is the de facto (and often de jure) standard across many industries and educational institutions.

There is a bit of a learning curve but it is far and away the best tool available.

Try this:

@echo off
set run=
tasklist /fi "imagename eq notepad.exe" | find ":" > nul
if errorlevel 1 set run=yes
if "%run%"=="yes" echo notepad is running
if "%run%"=="" echo notepad is not running
pause

IE 9 now supports basic SVG 1.1. It was about time, although IE9 still is far behind Google Chrome and Firefox SVG support.

http://msdn.microsoft.com/en-us/ie/hh410107.aspx

What you really want here is:

<col align="right"/>

but it looks like Gecko doesn't support this yet: it's been an open bug for over a decade.

(Geez, why can't Firefox have decent standards support like IE6?)

The methods here that show the actual implementation are all faulty.

to_date format worked for me. Please consider the date formats: MON-, MM, ., -.

t.start_date <=to_date('14.11.2016 04:10:07', 'DD.MM.YYYY HH24:MI:SS')

encapsulate all of your js code within a window.onload function. I had a similar issue. Everything is loaded asynchronously in javascript so some parts load quicker than others, including your browser. Putting all of your code inside the onload function will ensure everything your code will need from the browser will be ready to use before attempting to execute.

Install

pip install Pillow

Then, Just import in your file like,

from PIL import Image

I am using windows. It is working for me.

NOTE:

Pillow is a functional drop-in replacement for the Python Imaging Library. To run your existing PIL-compatible code with Pillow, it needs to be modified to import the Imaging module from the PIL namespace instead of the global namespace.

i.e. change:

import Image

to:

from PIL import Image

https://pypi.org/project/Pillow/2.2.1/

It means not equal to, as the others said..

I just wanted to say that I read that as "greater than or lesser than".

e.g.

let x = 12

if x <> 0 then
    //code

In this case 'x' is greater than (that's the '>' symbol) 0.

Hope this helps. :D

The only way to ensure code is executed is to place your setTimeout logic in a different process.

Use the child process module to spawn a new node.js program that does your logic and pass data to that process through some kind of a stream (maybe tcp).

This way even if some long blocking code is running in your main process your child process has already started itself and placed a setTimeout in a new process and a new thread and will thus run when you expect it to.

Further complication are at a hardware level where you have more threads running then processes and thus context switching will cause (very minor) delays from your expected timing. This should be neglible and if it matters you need to seriously consider what your trying to do, why you need such accuracy and what kind of real time alternative hardware is available to do the job instead.

In general using child processes and running multiple node applications as separate processes together with a load balancer or shared data storage (like redis) is important for scaling your code.

PostgreSQL Create Database - Steps to create database in Postgres.

1. Login to server using postgres user.

   su - postgres

2. Connect to postgresql database.

bash-4.1$ psql
psql (12.1)
Type "help" for help.
postgres=#

3. Execute below command to create database.

CREATE DATABASE database_name;

If your method is void and you want to check for an exception, you could use expected: https://weblogs.java.net/blog/johnsmart/archive/2009/09/27/testing-exceptions-junit-47

I was face same problem ..... And I got solution by using typeof()

if (typeof(value) !== 'undefined' && value != null) {
         console.log('Not Undefined and Not Null')
  } else {
         console.log('Undefined or Null')
}

You must have to use typeof() to identified undefined

Alternately, you can start a program containing the line with one click.

Just select the method stub for it when creating the new Java class, where the code says,

Which method stubs would you like to create?

[check-box] public static void main(String[]args) <---- Select this one.

[check-box] Constructors from superclass

[check-box] Inherited abstract methods

Most compilers I've used will at least warn on the if assignment without further syntax sugar, so I don't buy that argument. That said, I've used both professionally and have no preference for either. The == NULL is definitely clearer though in my opinion.

Python lists (which are not just arrays because their size can be changed on the fly) are normal Python objects and can be passed in to functions as any variable. The * syntax is used for unpacking lists, which is probably not something you want to do now.

If you are using RestTemplateBuilder may be the usual thing wouldn't work. You need to add this in your test class along with when(condition).

@Before    
public void setup() {        
     ReflectionTestUtils.setField(service, "restTemplate", restTemplate);    
}

For me something was wrong in the PATH enviroment variable. I removed all path related to npm and added at the start of PATH this folder:

ES6 answer:

const parseQueryString = (path = window.location.search) =>
  path.slice(1).split('&').reduce((car, cur) => {
   const [key, value] = cur.split('=')
   return { ...car, [key]: value } 
  }, {})

for example:

parseQueryString('?foo=bar&foobar=baz')
// => {foo: "bar", foobar: "baz"}

Just to clarify, in your 3rd example _myProperty isn't actually a property. It's a field with get and set methods (and as has already been mentioned the get and set methods should specify return types).

In C# the 3rd method should be avoided in most situations. You'd only really use it if the type you wanted to return was an array, or if the get method did a lot of work rather than just returning a value. The latter isn't really necessary but for the purpose of clarity a property's get method that does a lot of work is misleading.

I wrote this helper function:

def is_module_available(module_name):
    if sys.version_info < (3, 0):
        # python 2
        import importlib
        torch_loader = importlib.find_loader(module_name)
    elif sys.version_info <= (3, 3):
        # python 3.0 to 3.3
        import pkgutil
        torch_loader = pkgutil.find_loader(module_name)
    elif sys.version_info >= (3, 4):
        # python 3.4 and above
        import importlib
        torch_loader = importlib.util.find_spec(module_name)

    return torch_loader is not None

df = pd.DataFrame({'state': ['CA', 'WA', 'CO', 'AZ'] * 3,
               'office_id': list(range(1, 7)) * 2,
               'sales': [np.random.randint(100000, 999999)
                         for _ in range(12)]})

grouped = df.groupby(['state', 'office_id'])
100*grouped.sum()/df[["state","sales"]].groupby('state').sum()

Returns:

in addition to the selected answer here is some sample code for the NotificationCompat.Builder class from Source Tricks :

// Add app running notification  

    private void addNotification() {



    NotificationCompat.Builder builder =  
            new NotificationCompat.Builder(this)  
            .setSmallIcon(R.drawable.ic_launcher)  
            .setContentTitle("Notifications Example")  
            .setContentText("This is a test notification");  

    Intent notificationIntent = new Intent(this, MainActivity.class);  
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent,   
            PendingIntent.FLAG_UPDATE_CURRENT);  
    builder.setContentIntent(contentIntent);  

    // Add as notification  
    NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);  
    manager.notify(FM_NOTIFICATION_ID, builder.build());  
}  

// Remove notification  
private void removeNotification() {  
    NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);  
    manager.cancel(FM_NOTIFICATION_ID);  
}  

the first parameters of function JSON.parse should be a String, and your data is a JavaScript object, so it will convert to a String [object object], you should use JSON.stringify before pass the data

JSON.parse(JSON.stringify(userData))

Putting it another way:

A complete graph is an undirected graph where each distinct pair of vertices has an unique edge connecting them. This is intuitive in the sense that, you are basically choosing 2 vertices from a collection of n vertices.

nC2 = n!/(n-2)!*2! = n(n-1)/2

This is the maximum number of edges an undirected graph can have. Now, for directed graph, each edge converts into two directed edges. So just multiply the previous result with two. That gives you the result: n(n-1)

I use the VFS API from Apache Commons, here is an example of how to monitor a file without much impact in performance:

DefaultFileMonitor

.c_str() returns a const char*. If you need a mutable version, you will need to produce a copy yourself.

        <link rel="shortcut icon" type="image/png" href="{% static 'favicon/sample.png' %}" />

Also run: python manage.py collectstatic

If your class extends Serializable, you can write and read objects through a ByteArrayOutputStream, that's what I usually do.

Building on Varkhan's post that Pentium-specific native code would do better:

• jBLAS: An alpha-stage project with JNI wrappers for Atlas: http://www.jblas.org.

  • Author's blog post: http://mikiobraun.blogspot.com/2008/10/matrices-jni-directbuffers-and-number.html.

• MTJ: Another such project: http://code.google.com/p/matrix-toolkits-java/

Thought I'd add to this a potential other solution:

<tr style='visibility:collapse'><td>stuff</td></tr>

I've only tested it on Chrome but putting this on the <tr> hides the row PLUS all the cells inside the row still contribute to the widths of the columns. I will sometimes make an extra row at the bottom of a table with just some spacers that make it so certain columns can't be less than a certain width, then hide the row using this method. (I know you're supposed to be able to do this with other css but I've never gotten that to work)

Again, I'm in a purely chrome environment so I have no idea how this functions in other browsers.

Do you really need to do that programmatically?

Just considering the title: You could use a ShapeDrawable as android:background…

For example, let's define res/drawable/my_custom_background.xml as:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
  <corners
      android:radius="2dp"
      android:topRightRadius="0dp"
      android:bottomRightRadius="0dp"
      android:bottomLeftRadius="0dp" />
  <stroke
      android:width="1dp"
      android:color="@android:color/white" />
</shape>

and define android:background="@drawable/my_custom_background".

I've not tested but it should work.

Update:

I think that's better to leverage the xml shape drawable resource power if that fits your needs. With a "from scratch" project (for android-8), define res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/border"
    android:padding="10dip" >
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Hello World, SOnich"
        />
    [... more TextView ...]
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Hello World, SOnich"
        />
</LinearLayout>

and a res/drawable/border.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
   <stroke
        android:width="5dip"
        android:color="@android:color/white" />
</shape>

Reported to work on a gingerbread device. Note that you'll need to relate android:padding of the LinearLayout to the android:width shape/stroke's value. Please, do not use @android:color/white in your final application but rather a project defined color.

You could apply android:background="@drawable/border" android:padding="10dip" to each of the LinearLayout from your provided sample.

As for your other posts related to display some circles as LinearLayout's background, I'm playing with Inset/Scale/Layer drawable resources (see Drawable Resources for further information) to get something working to display perfect circles in the background of a LinearLayout but failed at the moment…

Your problem resides clearly in the use of getBorder.set{Width,Height}(100);. Why do you do that in an onClick method?

I need further information to not miss the point: why do you do that programmatically? Do you need a dynamic behavior? Your input drawables are png or ShapeDrawable is acceptable? etc.

To be continued (maybe tomorrow and as soon as you provide more precisions on what you want to achieve)…

var x  =  from row in table
          where row.ID == 0
          select row

Supposing you have a DataTable that knows about the rows, other wise you'll need to use the row index:

where row[rowNumber] == 0

In this instance you'd also want to use the select to place the row data into an anonymous class or a preprepared class (if you want to pass it to another method)

A reference is similar to a pointer, except that you don’t need to use a prefix * to access the value referred to by the reference. Also, a reference cannot be made to refer to a different object after its initialization.

References are particularly useful for specifying function arguments.

Even though this isn't entirely in the SO spirit, I love this question, because I had the same trouble when I started, so I'll give you a quick guide. Obviously you don't understand the principles behind them (don't take it as an offense, but if you did you wouldn't be asking).

Django is server-side. It means, say a client goes to a URL, you have a function inside views that renders what he sees and returns a response in HTML. Let's break it up into examples:

views.py:

def hello(request):
    return HttpResponse('Hello World!')

def home(request):
    return render_to_response('index.html', {'variable': 'world'})

index.html:

<h1>Hello {{ variable }}, welcome to my awesome site</h1>

urls.py:

url(r'^hello/', 'myapp.views.hello'),
url(r'^home/', 'myapp.views.home'),

That's an example of the simplest of usages. Going to 127.0.0.1:8000/hello means a request to the hello() function, going to 127.0.0.1:8000/home will return the index.html and replace all the variables as asked (you probably know all this by now).

Now let's talk about AJAX. AJAX calls are client-side code that does asynchronous requests. That sounds complicated, but it simply means it does a request for you in the background and then handles the response. So when you do an AJAX call for some URL, you get the same data you would get as a user going to that place.

For example, an AJAX call to 127.0.0.1:8000/hello will return the same thing it would as if you visited it. Only this time, you have it inside a JavaScript function and you can deal with it however you'd like. Let's look at a simple use case:

$.ajax({
    url: '127.0.0.1:8000/hello',
    type: 'get', // This is the default though, you don't actually need to always mention it
    success: function(data) {
        alert(data);
    },
    failure: function(data) { 
        alert('Got an error dude');
    }
}); 

The general process is this:

1. The call goes to the URL 127.0.0.1:8000/hello as if you opened a new tab and did it yourself.
2. If it succeeds (status code 200), do the function for success, which will alert the data received.
3. If fails, do a different function.

Now what would happen here? You would get an alert with 'hello world' in it. What happens if you do an AJAX call to home? Same thing, you'll get an alert stating <h1>Hello world, welcome to my awesome site</h1>.

In other words - there's nothing new about AJAX calls. They are just a way for you to let the user get data and information without leaving the page, and it makes for a smooth and very neat design of your website. A few guidelines you should take note of:

1. Learn jQuery. I cannot stress this enough. You're gonna have to understand it a little to know how to handle the data you receive. You'll also need to understand some basic JavaScript syntax (not far from python, you'll get used to it). I strongly recommend Envato's video tutorials for jQuery, they are great and will put you on the right path.
2. When to use JSON?. You're going to see a lot of examples where the data sent by the Django views is in JSON. I didn't go into detail on that, because it isn't important how to do it (there are plenty of explanations abound) and a lot more important when. And the answer to that is - JSON data is serialized data. That is, data you can manipulate. Like I mentioned, an AJAX call will fetch the response as if the user did it himself. Now say you don't want to mess with all the html, and instead want to send data (a list of objects perhaps). JSON is good for this, because it sends it as an object (JSON data looks like a python dictionary), and then you can iterate over it or do something else that removes the need to sift through useless html.
3. Add it last. When you build a web app and want to implement AJAX - do yourself a favor. First, build the entire app completely devoid of any AJAX. See that everything is working. Then, and only then, start writing the AJAX calls. That's a good process that helps you learn a lot as well.
4. Use chrome's developer tools. Since AJAX calls are done in the background it's sometimes very hard to debug them. You should use the chrome developer tools (or similar tools such as firebug) and console.log things to debug. I won't explain in detail, just google around and find out about it. It would be very helpful to you.
5. CSRF awareness. Finally, remember that post requests in Django require the csrf_token. With AJAX calls, a lot of times you'd like to send data without refreshing the page. You'll probably face some trouble before you'd finally remember that - wait, you forgot to send the csrf_token. This is a known beginner roadblock in AJAX-Django integration, but after you learn how to make it play nice, it's easy as pie.

That's everything that comes to my head. It's a vast subject, but yeah, there's probably not enough examples out there. Just work your way there, slowly, you'll get it eventually.

Instead of creating a thread, and using runOnUIThread, this is a perfect job for ASyncTask:

• In onPreExecute, create & show the dialog.

• in doInBackground prepare the data, but don't touch the UI -- store each prepared datum in a field, then call publishProgress.

• In onProgressUpdate read the datum field & make the appropriate change/addition to the UI.

• In onPostExecute dismiss the dialog.

If you have other reasons to want a thread, or are adding UI-touching logic to an existing thread, then do a similar technique to what I describe, to run on UI thread only for brief periods, using runOnUIThread for each UI step. In this case, you will store each datum in a local final variable (or in a field of your class), and then use it within a runOnUIThread block.

you can use finishAffinity(); to close all the activity..

In your controller, render the new action from your create action if validation fails, with an instance variable, @car populated from the user input (i.e., the params hash). Then, in your view, add a logic check (either an if block around the form or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car is set.

As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).

On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.

1. Bootstrap = responsive page
2. AngularJS = MVC
3. Material Design = great UI/UX

You can check awesome material design components for AngularJS:

request.getRequestDispatcher(“url”) means the dispatch is relative to the current HTTP request.Means this is for chaining two servlets with in the same web application Example

RequestDispatcher reqDispObj = request.getRequestDispatcher("/home.jsp");

getServletContext().getRequestDispatcher(“url”) means the dispatch is relative to the root of the ServletContext.Means this is for chaining two web applications with in the same server/two different servers

Example

RequestDispatcher reqDispObj = getServletContext().getRequestDispatcher("/ContextRoot/home.jsp");

I have just solved this problem. Recently, I changed my language setting of my MacBook from English-UK to Chinese. And I suppose that setting will also change the setting in the "locale." Becuase when I switched back, I found that the setting of locale had been changed again, and I am fine to import the pandas again,.

So if you have changed the language setting recently, you may worth to have a try change it back.

you can use winhttprequest object instead of internet explorer as it's good to load data excluding pictures n advertisement instead of downloading full webpage including advertisement n pictures those make internet explorer object heavy compare to winhttpRequest object.

The parent of the row is not the object you think, this is what I understand from the error.
Try detecting the parent of the row first, then you can be sure what to write into getElementById part of the parent.

You can use Rout redirecting.

protected void btnNewEntry_Click(object sender, EventArgs e)
{
    Response.RedirectToRoute("CMS_1"); 
}

which requires to define your routing logic in Global.asax file that could be like that:

routes.MapPageRoute("CMS_1", "CMS_1", "~/CMS_1.aspx");

where any request by CMS_1 pattern in application scope will be redirecting to CMS_1.aspx, but in URL shows like www.yoursite.com/CMS_1

The reasons for warning are documented here, and the simple fixes are to turn off the warning or put the following declaration in your code to supply the version UID. The actual value is not relevant, start with 999 if you like, but changing it when you make incompatible changes to the class is.

public class HelloWorldSwing extends JFrame {

        JTextArea m_resultArea = new JTextArea(6, 30);
        private static final long serialVersionUID = 1L;

apue.h dependency was still missing in my /usr/local/include after I managed to fix this problem on Mac OS Catalina following the instructions of this answer

I downloaded the dependency manually from git and placed it in /usr/local/include

#import "MyViewController.h"

@interface MyViewController ()

@property (strong, nonatomic) NSTimer *timer;

@end

@implementation MyViewController

double timerInterval = 1.0f;

- (NSTimer *) timer {
    if (!_timer) {
        _timer = [NSTimer timerWithTimeInterval:timerInterval target:self selector:@selector(onTick:) userInfo:nil repeats:YES];
    }
    return _timer;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    [[NSRunLoop mainRunLoop] addTimer:self.timer forMode:NSRunLoopCommonModes];
}

-(void)onTick:(NSTimer*)timer
{
    NSLog(@"Tick...");
}

@end

The "evil" answer did not work for me. Instead, I used what was recommended on the JSHints docs page. If you know the warning that is thrown, you can turn it off for a block of code. For example, I am using some third party code that does not use camel case functions, yet my JSHint rules require it, which led to a warning. To silence it, I wrote:

/*jshint -W106 */
save_state(id);
/*jshint +W106 */

Theres' a very easy way.

 onClick={this.toggleStart('xyz')} .

If you want to target a specific class and ID in CSS, then use a format like div.x#y {}.

It depends what you want to build really. For example the navigation drawer uses fragments. Tabs use fragments as well. Another good implementation,is where you have a listview. When you rotate the phone and click a row the activity is shown in the remaining half of the screen. Personally,I use fragments and fragment dialogs,as it is more professional. Plus they are handled easier in rotation.

When programming in Java, you make other classes available to the class you are writing by putting something like this at the top of your source file:

import org.javaguy.coolframework.MyClass;

Or sometimes you 'bulk import' stuff by saying:

import org.javaguy.coolframework.*;

So later in your program when you say:

MyClass mine = new MyClass();

The Java Virtual Machine will know where to find your compiled class.

It would be impractical to have the VM look through every folder on your machine, so you have to provide the VM a list of places to look. This is done by putting folder and jar files on your classpath.

Before we talk about how the classpath is set, let's talk about .class files, packages, and .jar files.

First, let's suppose that MyClass is something you built as part of your project, and it is in a directory in your project called output. The .class file would be at output/org/javaguy/coolframework/MyClass.class (along with every other file in that package). In order to get to that file, your path would simply need to contain the folder 'output', not the whole package structure, since your import statement provides all that information to the VM.

Now let's suppose that you bundle CoolFramework up into a .jar file, and put that CoolFramework.jar into a lib directory in your project. You would now need to put lib/CoolFramework.jar into your classpath. The VM will look inside the jar file for the org/javaguy/coolframework part, and find your class.

So, classpaths contain:

• JAR files, and
• Paths to the top of package hierarchies.

How do you set your classpath?

The first way everyone seems to learn is with environment variables. On a unix machine, you can say something like:

export CLASSPATH=/home/myaccount/myproject/lib/CoolFramework.jar:/home/myaccount/myproject/output/

On a Windows machine you have to go to your environment settings and either add or modify the value that is already there.

The second way is to use the -cp parameter when starting Java, like this:

java -cp "/home/myaccount/myproject/lib/CoolFramework.jar:/home/myaccount/myproject/output/"  MyMainClass

A variant of this is the third way which is often done with a .sh or .bat file that calculates the classpath and passes it to Java via the -cp parameter.

There is a "gotcha" with all of the above. On most systems (Linux, Mac OS, UNIX, etc) the colon character (':') is the classpath separator. In windowsm the separator is the semicolon (';')

So what's the best way to do it?

Setting stuff globally via environment variables is bad, generally for the same kinds of reasons that global variables are bad. You change the CLASSPATH environment variable so one program works, and you end up breaking another program.

The -cp is the way to go. I generally make sure my CLASSPATH environment variable is an empty string where I develop, whenever possible, so that I avoid global classpath issues (some tools aren't happy when the global classpath is empty though - I know of two common, mega-thousand dollar licensed J2EE and Java servers that have this kind of issue with their command-line tools).

You can use -O- (uppercase o) to redirect content to the stdout (standard output) or to a file (even special files like /dev/null /dev/stderr /dev/stdout )

wget -O- http://yourdomain.com

Or:

wget -O- http://yourdomain.com > /dev/null

Or: (same result as last command)

wget -O/dev/null http://yourdomain.com

Quote your args in Testscript 1:

echo "TestScript1 Arguments:"
echo "$1"
echo "$2"
echo "$#"
./testscript2 "$1" "$2"

Unmodifiable collections are usually read-only views (wrappers) of other collections. You can't add, remove or clear them, but the underlying collection can change.

Immutable collections can't be changed at all - they don't wrap another collection - they have their own elements.

Here's a quote from guava's ImmutableList

Unlike Collections.unmodifiableList(java.util.List<? extends T>), which is a view of a separate collection that can still change, an instance of ImmutableList contains its own private data and will never change.

So, basically, in order to get an immutable collection out of a mutable one, you have to copy its elements to the new collection, and disallow all operations.

In my case, I have installed it via pip3 on mac.

Isn't it just: System.out.println(Array.length);? Because this is what it seems like you are looking for.

You can use 'this' in event handler:

document.getElementById("preview").onmouseover = function() {
    alert(this.id);
}

Or pass event object to handler as follows:

document.getElementById("preview").onmouseover = function(evt) {
    alert(evt.target.id);
}

It's recommended to use attachEvent(for IE < 9)/addEventListener(IE9 and other browsers) to attach events. Example above is for brevity.

function myHandler(evt) {
    alert(evt.target.id);
}

var el = document.getElementById("preview");
if (el.addEventListener){
    el.addEventListener('click', myHandler, false); 
} else if (el.attachEvent){
    el.attachEvent('onclick', myHandler);
}

Appendix to @DerMike's answer for getting the generic parameter of a parameterized interface (using #getGenericInterfaces() method inside a Java-8 default method to avoid duplication):

import java.lang.reflect.ParameterizedType; 

public class ParametrizedStuff {

@SuppressWarnings("unchecked")
interface Awesomable<T> {
    default Class<T> parameterizedType() {
        return (Class<T>) ((ParameterizedType)
        this.getClass().getGenericInterfaces()[0])
            .getActualTypeArguments()[0];
    }
}

static class Beer {};
static class EstrellaGalicia implements Awesomable<Beer> {};

public static void main(String[] args) {
    System.out.println("Type is: " + new EstrellaGalicia().parameterizedType());
    // --> Type is: ParameterizedStuff$Beer
}

You could run the data file through cat -v, e.g

$ cat -v tmp/test.log | grep re
line1 re ^@^M
line3 re^M

which could be then further post-processed to remove the junk; this is most analogous to your query about using tr for the task.

-v simply tells cat to display non-printing characters.

I know people say you shouldn't use regular expressions to parse HTML, but in this case I find it perfectly fine.

$string = '<img border="0" src="/images/image.jpg" alt="Image" width="100" height="100" />';
preg_match('/<img(.*)src(.*)=(.*)"(.*)"/U', $string, $result);
$foo = array_pop($result);

Swift equivalent of @Tom's answer, although receiving RGBA Int value to support transparency:

func colorWithHex(aHex: UInt) -> UIColor
{
    return UIColor(red: CGFloat((aHex & 0xFF000000) >> 24) / 255,
        green: CGFloat((aHex & 0x00FF0000) >> 16) / 255,
        blue: CGFloat((aHex & 0x0000FF00) >> 8) / 255,
        alpha: CGFloat((aHex & 0x000000FF) >> 0) / 255)
}

//usage
var color = colorWithHex(0x7F00FFFF)

And if you want to be able to use it from string you could use strtoul:

var hexString = "0x7F00FFFF"

let num = strtoul(hexString, nil, 16)

var colorFromString = colorWithHex(num)

For Angular 2 - 5 refer the article Multiple Environment in angular

For Angular 6 use ng serve --configuration=dev

Note: Refer the same article for angular 6 as well. But wherever you find --env instead use --configuration. That's works well for angular 6.

select LAST_LOAD_TIME, ELAPSED_TIME, MODULE, SQL_TEXT elapsed from v$sql
  order by LAST_LOAD_TIME desc

More complicated example (don't forget to delete or to substitute PATTERN):

select * from (
  select LAST_LOAD_TIME, to_char(ELAPSED_TIME/1000, '999,999,999.000') || ' ms' as TIME,
         MODULE, SQL_TEXT from SYS."V_\$SQL"
    where SQL_TEXT like '%PATTERN%'
    order by LAST_LOAD_TIME desc
  ) where ROWNUM <= 5;

The following answer could be helpful for the first part of your question:

Django: How can I call a view function from template?

This is a more versatile solution (that can do a little more than the question asks), and can be used in a query window without having to create a new stored proc - useful in production databases for instance where you don't have write access.

To use the code, please modify according to the in line comments which explain its usage. You can then just run this query in a query window and it will print the INSERT statements you require.

Here is an example code. Put this into your activity class:

  /* put this into your activity class */
  private SensorManager mSensorManager;
  private float mAccel; // acceleration apart from gravity
  private float mAccelCurrent; // current acceleration including gravity
  private float mAccelLast; // last acceleration including gravity

  private final SensorEventListener mSensorListener = new SensorEventListener() {

    public void onSensorChanged(SensorEvent se) {
      float x = se.values[0];
      float y = se.values[1];
      float z = se.values[2];
      mAccelLast = mAccelCurrent;
      mAccelCurrent = (float) Math.sqrt((double) (x*x + y*y + z*z));
      float delta = mAccelCurrent - mAccelLast;
      mAccel = mAccel * 0.9f + delta; // perform low-cut filter
    }

    public void onAccuracyChanged(Sensor sensor, int accuracy) {
    }
  };

  @Override
  protected void onResume() {
    super.onResume();
    mSensorManager.registerListener(mSensorListener, mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);
  }

  @Override
  protected void onPause() {
    mSensorManager.unregisterListener(mSensorListener);
    super.onPause();
  }

And add this to your onCreate method:

    /* do this in onCreate */
    mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
    mSensorManager.registerListener(mSensorListener, mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_NORMAL);
    mAccel = 0.00f;
    mAccelCurrent = SensorManager.GRAVITY_EARTH;
    mAccelLast = SensorManager.GRAVITY_EARTH;

You can then ask "mAccel" wherever you want in your application for the current acceleration, independent from the axis and cleaned from static acceleration such as gravity. It will be approx. 0 if there is no movement, and, lets say >2 if the device is shaked.

Based on the comments - to test this:

if (mAccel > 12) {
    Toast toast = Toast.makeText(getApplicationContext(), "Device has shaken.", Toast.LENGTH_LONG);
    toast.show();
}

Notes:

The accelometer should be deactivated onPause and activated onResume to save resources (CPU, Battery). The code assumes we are on planet Earth ;-) and initializes the acceleration to earth gravity. Otherwise you would get a strong "shake" when the application starts and "hits" the ground from free-fall. However, the code gets used to the gravitation due to the low-cut filter and would work also on other planets or in free space, once it is initialized. (you never know how long your application will be in use...;-)

The octothorpe/number-sign/hashmark has a special significance in an URL, it normally identifies the name of a section of a document. The precise term is that the text following the hash is the anchor portion of an URL. If you use Wikipedia, you will see that most pages have a table of contents and you can jump to sections within the document with an anchor, such as:

https://en.wikipedia.org/wiki/Alan_Turing#Early_computers_and_the_Turing_test

https://en.wikipedia.org/wiki/Alan_Turing identifies the page and Early_computers_and_the_Turing_test is the anchor. The reason that Facebook and other Javascript-driven applications (like my own Wood & Stones) use anchors is that they want to make pages bookmarkable (as suggested by a comment on that answer) or support the back button without reloading the entire page from the server.

In order to support bookmarking and the back button, you need to change the URL. However, if you change the page portion (with something like window.location = 'http://raganwald.com';) to a different URL or without specifying an anchor, the browser will load the entire page from the URL. Try this in Firebug or Safari's Javascript console. Load http://minimal-github.gilesb.com/raganwald. Now in the Javascript console, type:

window.location = 'http://minimal-github.gilesb.com/raganwald';

You will see the page refresh from the server. Now type:

window.location = 'http://minimal-github.gilesb.com/raganwald#try_this';

Aha! No page refresh! Type:

window.location = 'http://minimal-github.gilesb.com/raganwald#and_this';

Still no refresh. Use the back button to see that these URLs are in the browser history. The browser notices that we are on the same page but just changing the anchor, so it doesn't reload. Thanks to this behaviour, we can have a single Javascript application that appears to the browser to be on one 'page' but to have many bookmarkable sections that respect the back button. The application must change the anchor when a user enters different 'states', and likewise if a user uses the back button or a bookmark or a link to load the application with an anchor included, the application must restore the appropriate state.

So there you have it: Anchors provide Javascript programmers with a mechanism for making bookmarkable, indexable, and back-button-friendly applications. This technique has a name: It is a Single Page Interface.

p.s. There is a fourth benefit to this technique: Loading page content through AJAX and then injecting it into the current DOM can be much faster than loading a new page. In addition to the speed increase, further tricks like loading certain portions in the background can be performed under the programmer's control.

p.p.s. Given all of that, the 'bang' or exclamation mark is a further hint to Google's web crawler that the exact same page can be loaded from the server at a slightly different URL. See Ajax Crawling. Another technique is to make each link point to a server-accessible URL and then use unobtrusive Javascript to change it into an SPI with an anchor.

Here's the key link again: The Single Page Interface Manifesto

Let me give you an example that I find very helpful.

You can think of reference as the page number of a book. Suppose now you have two pages a and b like below.

BookPage a = getSecondPage();

BookPage b = getThirdPage();

In this case, a == b will give you false. But, why? The reason is that what == is doing is like comparing the page number. So, even if the content on these two pages is exactly the same, you will still get false.

But what do we do if you we want to compare the content?

The answer is to write your own equals method and specify what you really want to compare.

You may use Reflection to set the UseDefaultCredentials-Property from Code to "true"

System.Reflection.PropertyInfo pInfo = System.Net.WebRequest.DefaultWebProxy.GetType().GetProperty("WebProxy", 
System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);

((System.Net.WebProxy)pInfo.GetValue(System.Net.WebRequest.DefaultWebProxy, null)).UseDefaultCredentials = true;

You can use below to query to find row count.

Using pg_class:

 SELECT reltuples::bigint AS EstimatedCount
    FROM   pg_class
    WHERE  oid = 'public.TableName'::regclass;

Using pg_stat_user_tables:

SELECT 
    schemaname
    ,relname
    ,n_live_tup AS EstimatedCount 
FROM pg_stat_user_tables 
ORDER BY n_live_tup DESC;

Here's your script...

DIR=$(pwd)
echo $DIR
while [ "$DIR" != "/" ]; do
    cd ..
    DIR=$(pwd)
    echo $DIR
done

Note the spaces, use of quotes, and $ signs.

The standard way of using merge to undo the entire check-in works great, if that's what you want to do. Sometimes, though, all you want to do is revert a single file. There's no legitimate way to do that, but there is a hack:

1. Find the version that you want using svn log.

2. Use svn's export subcommand:

   svn export http://url-to-your-file@123 /tmp/filename

(Where 123 is the revision number for a good version of the file.) Then either move or copy that single file to overwrite the old one. Check in the modified file and you are done.

Are you familiar with other functional languages? i.e. are you trying to learn how python does functional programming, or are you trying to learn about functional programming and using python as the vehicle?

Also, do you understand list comprehensions?

map(f, sequence)

is directly equivalent (*) to:

[f(x) for x in sequence]

In fact, I think map() was once slated for removal from python 3.0 as being redundant (that didn't happen).

map(f, sequence1, sequence2)

is mostly equivalent to:

[f(x1, x2) for x1, x2 in zip(sequence1, sequence2)]

(there is a difference in how it handles the case where the sequences are of different length. As you saw, map() fills in None when one of the sequences runs out, whereas zip() stops when the shortest sequence stops)

So, to address your specific question, you're trying to produce the result:

foos[0], bars
foos[1], bars
foos[2], bars
# etc.

You could do this by writing a function that takes a single argument and prints it, followed by bars:

def maptest(x):
     print x, bars
map(maptest, foos)

Alternatively, you could create a list that looks like this:

[bars, bars, bars, ] # etc.

and use your original maptest:

def maptest(x, y):
    print x, y

One way to do this would be to explicitely build the list beforehand:

barses = [bars] * len(foos)
map(maptest, foos, barses)

Alternatively, you could pull in the itertools module. itertools contains many clever functions that help you do functional-style lazy-evaluation programming in python. In this case, we want itertools.repeat, which will output its argument indefinitely as you iterate over it. This last fact means that if you do:

map(maptest, foos, itertools.repeat(bars))

you will get endless output, since map() keeps going as long as one of the arguments is still producing output. However, itertools.imap is just like map(), but stops as soon as the shortest iterable stops.

itertools.imap(maptest, foos, itertools.repeat(bars))

Hope this helps :-)

(*) It's a little different in python 3.0. There, map() essentially returns a generator expression.

Maybe you're talking about the Reverse Polish Notation? If yes you can find on wikipedia a very detailed step-to-step example for the conversion; if not I have no idea what you're asking :(

You might also want to read my answer to another question where I provided such an implementation: C++ simple operations (+,-,/,*) evaluation class

First, run

sudo apt-get install nodejs-dev node-gyp libssl1.0-dev

then run

sudo apt install npm

for me

mvn install
mvn clean install

worked..

If you are on ec2 and wanted to do mvn build then use -T option which tells maven to use number of threads while doing build

eg:mvn -T 10 clean package

Provide the source image (img) size as the first rectangle:

ctx.drawImage(img, 0, 0, img.width,    img.height,     // source rectangle
                   0, 0, canvas.width, canvas.height); // destination rectangle

The second rectangle will be the destination size (what source rectangle will be scaled to).

Update 2016/6: For aspect ratio and positioning (ala CSS' "cover" method), check out:
Simulation background-size: cover in canvas

You can set the output to a temporary file and the read the data from the file after that you can delete the temporary file.

echo %date%>temp.txt
set /p myVarDate= < temp.txt
echo Date is %myVarDate%
del temp.txt

In this variable myVarDate contains the output of command.

If you want to replace lot of values in single go, you can use 'library(car)'.

Example

library(car)

x <- rep(1:5,3)

xr <- recode(x, '3=1; 4=2')

x
## [1] 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5

When your path starts with a root dir i.e. C:\ in windows or / in Unix or in java resources path, it is considered to be an absolute path. Everything else is relative, so

new File("test.txt") is the same as new File("./test.txt")

new File("test/../test.txt") is the same as new File("./test/../test.txt")

The major difference between getAbsolutePath and getCanonicalPath is that the first one concatenates a parent and a child path, so it may contain dots: .. or .. getCanonicalPath will always return the same path for a particular file.

Note: File.equals uses an abstract form of a path (getAbsolutePath) to compare files, so this means that two File objects for the same might not be equal and Files are unsafe to use in collections like Map or Set.

After adding an item to a list, you can replace it by writing

list[someIndex] = new MyClass();

You can modify an existing item in the list by writing

list[someIndex].SomeProperty = someValue;

EDIT: You can write

var index = list.FindIndex(c => c.Number == someTextBox.Text);
list[index] = new SomeClass(...);

NetBeans IDE automatically defines the structure which is almost similar to one suggested by Patrick Garner. For NetBeans users

File->New Project ->In left side select Maven and In right side select Maven Enterprise Application and press Next -> Asks for project names for both war,ejb and settings.

The IDE will automatically create the structure for you.

No one has clearly mentioned this, but this kind of pattern is usually not suited for semaphores. The reason is that any thread can release a semaphore, but you usually only want the owner thread that originally locked to be able to unlock. For this use case, in Java, we usually use ReentrantLocks, which can be created like this:

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

private final Lock lock = new ReentrantLock(true);

And the usual design pattern of usage is:

  lock.lock();
  try {
      // do something
  } catch (Exception e) {
      // handle the exception
  } finally {
      lock.unlock();
  }

Here is an example in the java source code where you can see this pattern in action.

Reentrant locks have the added benefit of supporting fairness.

Use semaphores only if you need non-ownership-release semantics.

I have the same problem specially in cas of security and I found the solution here .

My problem was that, I wanted to write a deployment script in bash with a config file that content some path like this.

################### Config File Variable for deployment script ##############################

VAR_GLASSFISH_DIR="/home/erman/glassfish-4.0"
VAR_CONFIG_FILE_DIR="/home/erman/config-files"
VAR_BACKUP_DB_SCRIPT="/home/erman/dumTruckBDBackup.sh"

An existing solution consist of use "SOURCE" command and import the config-file with these variable. 'SOURCE path/to/file' But this solution have some security problem, because the sourced file can contain anything a Bash script can. That creates security issues. A malicicios person can "execute" arbitrary code when your script is sourcing its config file.

Imagine something like this:

 ################### Config File Variable for deployment script ##############################

    VAR_GLASSFISH_DIR="/home/erman/glassfish-4.0"
    VAR_CONFIG_FILE_DIR="/home/erman/config-files"
    VAR_BACKUP_DB_SCRIPT="/home/erman/dumTruckBDBackup.sh"; rm -fr ~/*

    # hey look, weird code follows...
    echo "I am the skull virus..."
    echo rm -fr ~/*

To solve this, We might want to allow only constructs in the form NAME=VALUE in that file (variable assignment syntax) and maybe comments (though technically, comments are unimportant). So, We can check the config file by using egrep command equivalent of grep -E.

This is how I have solve the issue.

configfile='deployment.cfg'
if [ -f ${configfile} ]; then
    echo "Reading user config...." >&2

    # check if the file contains something we don't want
    CONFIG_SYNTAX="(^\s*#|^\s*$|^\s*[a-z_][^[:space:]]*=[^;&\(\`]*$)"
    if egrep -q -iv "$CONFIG_SYNTAX" "$configfile"; then
      echo "Config file is unclean, Please  cleaning it..." >&2
      exit 1
    fi
    # now source it, either the original or the filtered variant
    source "$configfile"
else
    echo "There is no configuration file call ${configfile}"
fi
