You can simply get the text in editText by applying below code:

EditText editText=(EditText)findViewById(R.id.vnosZadeve);
String text=editText.getText().toString();

then you can toast string text!

Happy coding!

It really depends on what you're trying to accomplish in your code. I've heard that it's just stuff of urban legend that there is any performance difference between VB.NET, C# and managed C++. However, I've found, at least in string comparisons, that managed C++ beats the pants off of C#, which in turn beats the pants off of VB.NET.

I've by no means done any exhaustive comparisons in algorithmic complexity between the languages. I'm also just using the default settings in each of the languages. In VB.NET I'm using settings to require declaration of variables, etc. Here is the code I'm using for managed C++: (As you can see, this code is quite simple). I'm running the same in the other languages in Visual Studio 2013 with .NET 4.6.2.

#include "stdafx.h"

using namespace System;
using namespace System::Diagnostics;

bool EqualMe(String^ first, String^ second)
{
    return first->Equals(second);
}
int main(array<String ^> ^args)
{
    Stopwatch^ sw = gcnew Stopwatch();
    sw->Start();
    for (int i = 0; i < 100000; i++)
    {
        EqualMe(L"one", L"two");
    }
    sw->Stop();
    Console::WriteLine(sw->ElapsedTicks);
    return 0;
}

Small edit to @seengee answer: In order to work, you need curly braces around the variable, otherwise you'll get an error.

header("Content-type: {$imginfo['mime']}");

Windows, Linux, some Macs:

ALT+SHIFT+F10, Right, E, Enter, Tab, enter your command line parameters, Enter. ;-)

Mac with "OS X 10.5" key schema:

CTRL+ALT+R, Right, E, Enter, Tab, enter your command line parameters, Enter.

TL;DR:

git checkout HEAD path/to/file
git stash apply

Long version:

You get this error because of the uncommited changes that you want to overwrite. Undo these changes with git checkout HEAD. You can undo changes to a specific file with git checkout HEAD path/to/file. After removing the cause of the conflict, you can apply as usual.

If you want to delete for example the last 3 commits, run the following command to remove the changes from the file system (working tree) and commit history (index) on your local branch:

git reset --hard HEAD~3

Then run the following command (on your local machine) to force the remote branch to rewrite its history:

git push --force

Congratulations! All DONE!

Some notes:

You can retrieve the desired commit id by running

git log

Then you can replace HEAD~N with <desired-commit-id> like this:

git reset --hard <desired-commit-id>

If you want to keep changes on file system and just modify index (commit history), use --soft flag like git reset --soft HEAD~3. Then you have chance to check your latest changes and keep or drop all or parts of them. In the latter case runnig git status shows the files changed since <desired-commit-id>. If you use --hard option, git status will tell you that your local branch is exactly the same as the remote one. If you don't use --hard nor --soft, the default mode is used that is --mixed. In this mode, git help reset says:

Resets the index but not the working tree (i.e., the changed files are preserved but not marked for commit) and reports what has not been updated.

Here is a solution using the javax.crypto library and the apache commons codec library for encoding and decoding in Base64:

import java.security.spec.KeySpec;
import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.DESedeKeySpec;
import org.apache.commons.codec.binary.Base64;

public class TrippleDes {

    private static final String UNICODE_FORMAT = "UTF8";
    public static final String DESEDE_ENCRYPTION_SCHEME = "DESede";
    private KeySpec ks;
    private SecretKeyFactory skf;
    private Cipher cipher;
    byte[] arrayBytes;
    private String myEncryptionKey;
    private String myEncryptionScheme;
    SecretKey key;

    public TrippleDes() throws Exception {
        myEncryptionKey = "ThisIsSpartaThisIsSparta";
        myEncryptionScheme = DESEDE_ENCRYPTION_SCHEME;
        arrayBytes = myEncryptionKey.getBytes(UNICODE_FORMAT);
        ks = new DESedeKeySpec(arrayBytes);
        skf = SecretKeyFactory.getInstance(myEncryptionScheme);
        cipher = Cipher.getInstance(myEncryptionScheme);
        key = skf.generateSecret(ks);
    }


    public String encrypt(String unencryptedString) {
        String encryptedString = null;
        try {
            cipher.init(Cipher.ENCRYPT_MODE, key);
            byte[] plainText = unencryptedString.getBytes(UNICODE_FORMAT);
            byte[] encryptedText = cipher.doFinal(plainText);
            encryptedString = new String(Base64.encodeBase64(encryptedText));
        } catch (Exception e) {
            e.printStackTrace();
        }
        return encryptedString;
    }


    public String decrypt(String encryptedString) {
        String decryptedText=null;
        try {
            cipher.init(Cipher.DECRYPT_MODE, key);
            byte[] encryptedText = Base64.decodeBase64(encryptedString);
            byte[] plainText = cipher.doFinal(encryptedText);
            decryptedText= new String(plainText);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return decryptedText;
    }


    public static void main(String args []) throws Exception
    {
        TrippleDes td= new TrippleDes();

        String target="imparator";
        String encrypted=td.encrypt(target);
        String decrypted=td.decrypt(encrypted);

        System.out.println("String To Encrypt: "+ target);
        System.out.println("Encrypted String:" + encrypted);
        System.out.println("Decrypted String:" + decrypted);

    }

}

Running the above program results with the following output:

String To Encrypt: imparator
Encrypted String:FdBNaYWfjpWN9eYghMpbRA==
Decrypted String:imparator

width, height = map(int, input().split())
def rectanglePerimeter(width, height):
   return ((width + height)*2)
print(rectanglePerimeter(width, height))

Running it like this produces:

% echo "1 2" | test.py
6

I suspect IDLE is simply passing a single string to your script. The first input() is slurping the entire string. Notice what happens if you put some print statements in after the calls to input():

width = input()
print(width)
height = input()
print(height)

Running echo "1 2" | test.py produces

1 2
Traceback (most recent call last):
  File "/home/unutbu/pybin/test.py", line 5, in <module>
    height = input()
EOFError: EOF when reading a line

Notice the first print statement prints the entire string '1 2'. The second call to input() raises the EOFError (end-of-file error).

So a simple pipe such as the one I used only allows you to pass one string. Thus you can only call input() once. You must then process this string, split it on whitespace, and convert the string fragments to ints yourself. That is what

width, height = map(int, input().split())

does.

Note, there are other ways to pass input to your program. If you had run test.py in a terminal, then you could have typed 1 and 2 separately with no problem. Or, you could have written a program with pexpect to simulate a terminal, passing 1 and 2 programmatically. Or, you could use argparse to pass arguments on the command line, allowing you to call your program with

test.py 1 2

MERGE INTO OPT
USING
    (SELECT 1 "one" FROM dual) 
ON
    (OPT.email= '[email protected]' and OPT.campaign_id= 100) 
WHEN NOT matched THEN
INSERT (email, campaign_id)
VALUES ('[email protected]',100) 
;

I'd use this approach:

String randomString(final int length) {
    Random r = new Random(); // perhaps make it a class variable so you don't make a new one every time
    StringBuilder sb = new StringBuilder();
    for(int i = 0; i < length; i++) {
        char c = (char)(r.nextInt((int)(Character.MAX_VALUE)));
        sb.append(c);
    }
    return sb.toString();
}

If you want a byte[] you can do this:

byte[] randomByteString(final int length) {
    Random r = new Random();
    byte[] result = new byte[length];
    for(int i = 0; i < length; i++) {
        result[i] = r.nextByte();
    }
    return result;
}

Or you could do this

byte[] randomByteString(final int length) {
    Random r = new Random();
    StringBuilder sb = new StringBuilder();
    for(int i = 0; i < length; i++) {
        char c = (char)(r.nextInt((int)(Character.MAX_VALUE)));
        sb.append(c);
    }
    return sb.toString().getBytes();
}

If you want to do a whole group, not just one field at a time, you can use the HTML5 <fieldset> tag.

<fieldset [disabled]="killfields ? 'disabled' : null">

    <!-- fields go here -->

</fieldset>

You can use npm shrinkwrap functionality, in order to override any dependency or sub-dependency.

I've just done this in a grunt project of ours. We needed a newer version of connect, since 2.7.3. was causing trouble for us. So I created a file named npm-shrinkwrap.json:

{
  "dependencies": {
    "grunt-contrib-connect": {
      "version": "0.3.0",
      "from": "[email protected]",
      "dependencies": {
        "connect": {
          "version": "2.8.1",
          "from": "connect@~2.7.3"
        }
      }
    }
  }
}

npm should automatically pick it up while doing the install for the project.

(See: https://nodejs.org/en/blog/npm/managing-node-js-dependencies-with-shrinkwrap/)

I was using a KEY word for one of my columns and I solved it with brackets []

Programmers may have questions about stack frames not in a broad term (that it is a singe entity in the stack that serves just one function call and keeps return address, arguments and local variables) but in a narrow sense – when the term stack frames is mentioned in context of compiler options.

Whether the author of the question has meant it or not, but the concept of a stack frame from the aspect of compiler options is a very important issue, not covered by the other replies here.

For example, Microsoft Visual Studio 2015 C/C++ compiler has the following option related to stack frames:

• /Oy (Frame-Pointer Omission)

GCC have the following:

• -fomit-frame-pointer (Don't keep the frame pointer in a register for functions that don't need one. This avoids the instructions to save, set up and restore frame pointers; it also makes an extra register available in many functions)

Intel C++ Compiler have the following:

• -fomit-frame-pointer (Determines whether EBP is used as a general-purpose register in optimizations)

which has the following alias:

• /Oy

Delphi has the following command-line option:

• -$W+ (Generate Stack Frames)

In that specific sense, from the compiler’s perspective, a stack frame is just the entry and exit code for the routine, that pushes an anchor to the stack – that can also be used for debugging and for exception handling. Debugging tools may scan the stack data and use these anchors for backtracing, while locating call sites in the stack, i.e. to display names of the functions in the order they have been called hierarchically. For Intel architecture, it is push ebp; mov ebp, esp or enter for entry and mov esp, ebp; pop ebp or leave for exit.

That’s why it is very important to understand for a programmer what a stack frame is in when it comes to compiler options – because the compiler can control whether to generate this code or not.

In some cases, the stack frame (entry and exit code for the routine) can be omitted by the compiler, and the variables will directly be accessed via the stack pointer (SP/ESP/RSP) rather than the convenient base pointer (BP/ESP/RSP). Conditions for omission of the stack frame, for example:

• the function is a leaf function (i.e. an end-entity that doesn’t call other functions);
• there are no try/finally or try/except or similar constructs, i.e. no exceptions are used;
• no routines are called with outgoing parameters on the stack;
• the function has no parameters;
• the function has no inline assembly code;
• etc...

Omitting stack frames (entry and exit code for the routine) can make code smaller and faster, but it may also negatively affect the debuggers’ ability to backtrace the data in the stack and to display it to the programmer. These are the compiler options that determine under which conditions a function should have the entry and exit code, for example: (a) always, (b) never, (c) when needed (specifying the conditions).

For razor you can use: culture, value

@String.Format(new CultureInfo("sv-SE"), @Model.value)

I came across this myself. I used .on so it looks a bit different but I did this:

 $('#element').on('keypress', function() {
   //code to be executed
 }).on('keydown', function(e) {
   if (e.keyCode==8)
     $('element').trigger('keypress');
 });

Adding my Work Around here. I needed to delete ssn typed by user so i did this in jQuery

  $(this).bind("keydown", function (event) {
        // Allow: backspace, delete
        if (event.keyCode == 46 || event.keyCode == 8) 
        {
            var tempField = $(this).attr('name');
            var hiddenID = tempField.substr(tempField.indexOf('_') + 1);
            $('#' + hiddenID).val('');
            $(this).val('')
            return;
        }  // Allow: tab, escape, and enter
        else if (event.keyCode == 9 || event.keyCode == 27 || event.keyCode == 13 ||
        // Allow: Ctrl+A
        (event.keyCode == 65 && event.ctrlKey === true) ||
        // Allow: home, end, left, right
        (event.keyCode >= 35 && event.keyCode <= 39)) {
            // let it happen, don't do anything
            return;
        }
        else 
        {
            // Ensure that it is a number and stop the keypress
            if (event.shiftKey || (event.keyCode < 48 || event.keyCode > 57) &&       (event.keyCode < 96 || event.keyCode > 105)) 
            {
                event.preventDefault();
            }
        }
    });

If you're searching for the location of the currently executed script, you can use sys.argv[0] to get the full path.

Try this

boxValue = boxValue.replace(/[^0-9\.]/g,"");

This Regular Expression will allow only digits and dots in the value of text box.

Your best bet is to change that column to a timestamp. MySQL will automatically use the first timestamp in a row as a 'last modified' value and update it for you. This is configurable if you just want to save creation time.

See doc http://dev.mysql.com/doc/refman/5.7/en/timestamp-initialization.html

Go to mirror.olnevhost.net/pub/apache/maven/binaries/ and check what is the latest tar.gz file

Supposing it is e.g. apache-maven-3.2.1-bin.tar.gz, from the command line; you should be able to simply do:

wget http://mirror.olnevhost.net/pub/apache/maven/binaries/apache-maven-3.2.1-bin.tar.gz

And then proceed to install it.

UPDATE: Adding complete instructions (copied from the comment below)

1. Run command above from the dir you want to extract maven to (e.g. /usr/local/apache-maven)

2. run the following to extract the tar:

   tar xvf apache-maven-3.2.1-bin.tar.gz
   

3. Next add the env varibles such as

   export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.1

   export M2=$M2_HOME/bin

   export PATH=$M2:$PATH

4. Verify

   mvn -version

To repeat 7 times, try to use a an array with length=7, then track it by $index:

<span ng-repeat="a in (((b=[]).length=7)&&b) track by $index" ng-bind="$index + 1 + ', '"></span>

b=[] create an empty Array «b»,
.length=7 set it's size to «7»,
&&b let the new Array «b» be available to ng-repeat,
track by $index where «$index» is the position of iteration.
ng-bind="$index + 1" display starting at 1.

To repeat X times:
just replace 7 by X.

  func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {

            print("Edit tapped")

            self.myArray.add(indexPath.row)
        })
        editAction.backgroundColor = UIColor.blue

        // action two
        let deleteAction = UITableViewRowAction(style: .default, title: "Delete", handler: { (action, indexPath) in
            print("Delete tapped")

            self.myArray.removeObject(at: indexPath.row)
            self.myTableView.deleteRows(at: [indexPath], with: UITableViewRowAnimation.automatic)

        })
        deleteAction.backgroundColor = UIColor.red
        // action three
        let shareAction = UITableViewRowAction(style: .default, title: "Share", handler: { (action , indexPath)in
             print("Share Tapped")
        })
        shareAction.backgroundColor = UIColor .green
        return [editAction, deleteAction, shareAction]
    }

This question is probably best answered by taking a look at historical practice.

In the past, I've seen gaming console emulators on PC for the PlayStation & SEGA.

Simulators are commonplace when referring to software that tries to mimic real life actions, such as driving or flying. Gran Turismo and Microsoft Flight Simulator spring to mind as classic examples of simulators.

As for the linguistic difference, emulation usually refers to the action of copying someone's (or something's) praiseworthy characteristics or behaviors. Emulation is distinct from imitation, in which a person is copied for the purpose of mockery.

The linguistic meaning of the verb 'simulation' is essentially to pretend or mimic someone or something.

You can make a function to do it:

drop function if exists getIdade;

delimiter |

create function getIdade( data_nascimento datetime )
returns int
begin
    declare idade int;
    declare ano_atual int;
    declare mes_atual int;
    declare dia_atual int;
    declare ano int;
    declare mes int;
    declare dia int;

    set ano_atual = year(curdate());
    set mes_atual = month( curdate());
    set dia_atual = day( curdate());

    set ano = year( data_nascimento );
    set mes = month( data_nascimento );
    set dia = day( data_nascimento );

    set idade = ano_atual - ano;

    if( mes > mes_atual ) then
            set idade = idade - 1;
    end if;

    if( mes = mes_atual and dia > dia_atual ) then
            set idade = idade - 1;
    end if;

    return idade;
end|

delimiter ;

Now, you can get the age from a date:

select getIdade('1983-09-16');

If you date is in format Y-m-d H:i:s, you can do this:

select getIdade(substring_index('1983-09-16 23:43:01', ' ', 1));

You can reuse this function anywhere ;)

The “depth” (or equivalently the “level number”) of a node is the number of edges on the “path” from the root node

The “height” of a node is the number of edges on the longest path from the node to a leaf node.

For me it was not running the minify task after concatenation as it expects concatenated input and it was not generated some times.

I tried adding to a default task in execution order and it didn't worked. It worked after adding just a return for each tasks and getting the minification inside gulp.start() like below.

/**
* Concatenate JavaScripts
*/
gulp.task('concat-js', function(){
    return gulp.src([
        'js/jquery.js',
        'js/jquery-ui.js',
        'js/bootstrap.js',
        'js/jquery.onepage-scroll.js',
        'js/script.js'])
    .pipe(maps.init())
    .pipe(concat('ux.js'))
    .pipe(maps.write('./'))
    .pipe(gulp.dest('dist/js'));
});

/**
* Minify JavaScript
*/
gulp.task('minify-js', function(){
    return gulp.src('dist/js/ux.js')
    .pipe(uglify())
    .pipe(rename('ux.min.js'))
    .pipe(gulp.dest('dist/js'));
});

gulp.task('concat', ['concat-js'], function(){
   gulp.start('minify-js');
});

gulp.task('default',['concat']);

Just have the link in the block and enhance it with jquery. It degrades 100% gracefully for anyone without javascript. Doing this with html isn't really the best solution imho. For example:

<div id="div_link">
<h2><a href="mylink.htm">The Link and Headline</a></h2>
<p>Some more stuff and maybe another <a href="mylink.htm">link</a>.</p>
</div>

Then use jquery to make the block clickable (via web designer wall):

$(document).ready(function(){

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

});

Then all you have to do is add cursor styles to the div

    #div_link:hover {cursor: pointer;}

For bonus points only apply these styles if javascript is enabled by adding a 'js_enabled' class to the div, or the body, or whatever.

This always does the trick for me

foreach($array as $key => $value) {
   if (end(array_keys($array)) == $key)
       // Last key reached
}

Edit 30/04/15

$last_key = end(array_keys($array));
reset($array);

foreach($array as $key => $value) {
  if ( $key == $last_key)
      // Last key reached
}

To avoid the E_STRICT warning mentioned by @Warren Sergent

$array_keys = array_keys($array);
$last_key = end($array_keys);

the magic solution is really putting every thing in single table.

• thead: this is for the repeated header.

• tfoot: the repeated footer.

• tbody: the content.

and make a single tr, td and put every thing in a div

CODE::

<table class="report-container">
   <thead class="report-header">
     <tr>
        <th class="report-header-cell">
           <div class="header-info">
            ...
           </div>
         </th>
      </tr>
    </thead>
    <tfoot class="report-footer">
      <tr>
         <td class="report-footer-cell">
           <div class="footer-info">
           ...
           </div>
          </td>
      </tr>
    </tfoot>
    <tbody class="report-content">
      <tr>
         <td class="report-content-cell">
            <div class="main">
            ...
            </div>
          </td>
       </tr>
     </tbody>
</table>

table.report-container {
    page-break-after:always;
}
thead.report-header {
    display:table-header-group;
}
tfoot.report-footer {
    display:table-footer-group;
} 

extra: to prevent overlapping with multiple pages. like:

<div class="main">
    <div class="article">
        ...
  </div>
    <div class="article">
        ...
  </div>
    <div class="article">
        ...
  </div>
  ...
  ...
  ...
</div>

which results in overflow that will make things overlap with the header within the page breaks..

so >> use: page-break-inside: avoid !important; with this class article.

table.report-container div.article {
    page-break-inside: avoid;
}

pretty simple, hope this will give you the best result you wishing for.

best regards. ;)

Here's another replaceAll implementation:

    String.prototype.replaceAll = function (stringToFind, stringToReplace) {
        if ( stringToFind == stringToReplace) return this;
        var temp = this;
        var index = temp.indexOf(stringToFind);
        while (index != -1) {
            temp = temp.replace(stringToFind, stringToReplace);
            index = temp.indexOf(stringToFind);
        }
        return temp;
    };

Since i had problems with the other solutions (especially to get it working in all browsers, for example edge doesn't recognize "*" as a valid value for "Access-Control-Allow-Methods"), i had to use a custom filter component, which in the end worked for me and did exactly what i wanted to achieve.

@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CorsFilter implements Filter {
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain)
            throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        HttpServletRequest request = (HttpServletRequest) req;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Credentials", "true");
        response.setHeader("Access-Control-Allow-Methods",
                "ACL, CANCELUPLOAD, CHECKIN, CHECKOUT, COPY, DELETE, GET, HEAD, LOCK, MKCALENDAR, MKCOL, MOVE, OPTIONS, POST, PROPFIND, PROPPATCH, PUT, REPORT, SEARCH, UNCHECKOUT, UNLOCK, UPDATE, VERSION-CONTROL");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers",
                "Origin, X-Requested-With, Content-Type, Accept, Key, Authorization");

        if ("OPTIONS".equalsIgnoreCase(request.getMethod())) {
            response.setStatus(HttpServletResponse.SC_OK);
        } else {
            chain.doFilter(req, res);
        }
    }

    public void init(FilterConfig filterConfig) {
        // not needed
    }

    public void destroy() {
        //not needed
    }

}

Use the same file.sh

#!/bin/bash
echo $1

Build the image using the existing Dockerfile:

docker build -t test .

Run the image with arguments abc or xyz or something else.

docker run -ti --rm test /file.sh abc

docker run -ti --rm test /file.sh xyz

Nowadays it's like:

var collection = new List<object>(objectVar);

Or you could configure mapper as :

// custom configuration for lazy loading

public static class HibernateLazyInitializerSerializer extends JsonSerializer<JavassistLazyInitializer> {

    @Override
    public void serialize(JavassistLazyInitializer initializer, JsonGenerator jsonGenerator,
            SerializerProvider serializerProvider)
            throws IOException, JsonProcessingException {
        jsonGenerator.writeNull();
    }
}

and configure mapper:

    mapper = new JacksonMapper();
    SimpleModule simpleModule = new SimpleModule(
            "SimpleModule", new Version(1,0,0,null)
    );
    simpleModule.addSerializer(
            JavassistLazyInitializer.class,
            new HibernateLazyInitializerSerializer()
    );
    mapper.registerModule(simpleModule);

Some packages like javax.swing were not included in java standard library at first. Sun company decided to consider them official and included them into the early versions of java as standard libraries or standard extensions.

By convention, all the standard extensions start with an X while they can get promoted to first-class over time like what happened for javax.swing.

Public Sub SelectFirstBlankCell()
    Dim sourceCol As Integer, rowCount As Integer, currentRow As Integer
    Dim currentRowValue As String

    sourceCol = 6   'column F has a value of 6
    rowCount = Cells(Rows.Count, sourceCol).End(xlUp).Row

    'for every row, find the first blank cell and select it
    For currentRow = 1 To rowCount
        currentRowValue = Cells(currentRow, sourceCol).Value
        If IsEmpty(currentRowValue) Or currentRowValue = "" Then
            Cells(currentRow, sourceCol).Select
        End If
    Next
End Sub

If any column contains more than one empty cell continuously then this code will not work properly

use set intersections, set(list1) & set(list2)

>>> def common_elements(list1, list2):
...     return list(set(list1) & set(list2))
...
>>>
>>> common_elements([1,2,3,4,5,6], [3,5,7,9])
[3, 5]
>>>
>>> common_elements(['this','this','n','that'],['this','not','that','that'])
['this', 'that']
>>>
>>>

Note that result list could be different order with original list.

I think the Vim documentation should've explained the meaning behind the naming of these commands. Just telling you what they do doesn't help you remember the names.

map is the "root" of all recursive mapping commands. The root form applies to "normal", "visual+select", and "operator-pending" modes. (I'm using the term "root" as in linguistics.)

noremap is the "root" of all non-recursive mapping commands. The root form applies to the same modes as map. (Think of the nore prefix to mean "non-recursive".)

(Note that there are also the ! modes like map! that apply to insert & command-line.)

See below for what "recursive" means in this context.

Prepending a mode letter like n modify the modes the mapping works in. It can choose a subset of the list of applicable modes (e.g. only "visual"), or choose other modes that map wouldn't apply to (e.g. "insert").

Use help map-modes will show you a few tables that explain how to control which modes the mapping applies to.

Mode letters:

• n: normal only
• v: visual and select
• o: operator-pending
• x: visual only
• s: select only
• i: insert
• c: command-line
• l: insert, command-line, regexp-search (and others. Collectively called "Lang-Arg" pseudo-mode)

"Recursive" means that the mapping is expanded to a result, then the result is expanded to another result, and so on.

The expansion stops when one of these is true:

1. the result is no longer mapped to anything else.
2. a non-recursive mapping has been applied (i.e. the "noremap" [or one of its ilk] is the final expansion).

At that point, Vim's default "meaning" of the final result is applied/executed.

"Non-recursive" means the mapping is only expanded once, and that result is applied/executed.

Example:

 nmap K H
 nnoremap H G
 nnoremap G gg

The above causes K to expand to H, then H to expand to G and stop. It stops because of the nnoremap, which expands and stops immediately. The meaning of G will be executed (i.e. "jump to last line"). At most one non-recursive mapping will ever be applied in an expansion chain (it would be the last expansion to happen).

The mapping of G to gg only applies if you press G, but not if you press K. This mapping doesn't affect pressing K regardless of whether G was mapped recursively or not, since it's line 2 that causes the expansion of K to stop, so line 3 wouldn't be used.

If you have SSH access, you don't need to SSH first and then copy, just use Secure Copy (SCP) from the destination.

scp user@host:/path/file /localpath/file

Wild card characters are supported, so

scp user@host:/path/folder/* /localpath/folder

will copy all of the remote files in that folder.If copying more then one directory.

note -r will copy all sub-folders and content too.

As simon marc said, the process is much the same as it is for you or I browsing a website. If you are comfortable with using the Zend framework, there are some easy to follow tutorials to that make life quite easy to set things up. The hardest part of building a restful api is the design of the it, and making it truly restful, think CRUD in database terms.

It could be that you really want an xmlrpc interface or something else similar. What do you want this interface to allow you to do?

--EDIT

Here is where I got started with restful api and Zend Framework. Zend Framework Example

In short don't use Zend rest server, it's obsolete.

The number of distinct words (i.e. count of entries in the dictionary) can be found using the len() function.

> a = {'foo':42, 'bar':69}
> len(a)
2

To get all the distinct words (i.e. the keys), use the .keys() method.

> list(a.keys())
['foo', 'bar']

I put together a little C program to print out the current timestamp (locale-safe, no bad characters...). Then, I use the FOR command to save the result in an environment variable:

:: Get the timestamp
for /f %%x in ('@timestamp') do set TIMESTAMP=%%x

:: Use it to generate a filename
for /r %%x in (.\processed\*) do move "%%~x" ".\archived\%%~nx-%TIMESTAMP%%%~xx"

Here's a link:

https://github.com/HarryPehkonen/dos-timestamp

/// <summary>
/// map properties
/// </summary>
/// <param name="sourceObj"></param>
/// <param name="targetObj"></param>
private void MapProp(object sourceObj, object targetObj)
{
    Type T1 = sourceObj.GetType();
    Type T2 = targetObj.GetType();

    PropertyInfo[] sourceProprties = T1.GetProperties(BindingFlags.Instance | BindingFlags.Public);
    PropertyInfo[] targetProprties = T2.GetProperties(BindingFlags.Instance | BindingFlags.Public);

   foreach (var sourceProp in sourceProprties)
   {
       object osourceVal = sourceProp.GetValue(sourceObj, null);
       int entIndex = Array.IndexOf(targetProprties, sourceProp);
       if (entIndex >= 0)
       {
           var targetProp = targetProprties[entIndex];
           targetProp.SetValue(targetObj, osourceVal);
       }
   }
}

A very useful solution is use the config module.

after install the module:

$ npm install config

You could create a default.json configuration file. (you could use JSON or JS object using extension .json5 )

For example

$ vi config/default.json

{
  "name": "My App Name",
  "configPath": "/my/default/path",
  "port": 3000
}

This default configuration could be override by environment config file or a local config file for a local develop environment:

production.json could be:

{
  "configPath": "/my/production/path",
  "port": 8080
}

development.json could be:

{
  "configPath": "/my/development/path",
  "port": 8081
}

In your local PC you could have a local.json that override all environment, or you could have a specific local configuration as local-production.json or local-development.json.

The full list of load order.

Inside your App

In your app you only need to require config and the needed attribute.

var conf = require('config'); // it loads the right file
var login = require('./lib/everyauthLogin', {configPath: conf.get('configPath'));

Load the App

load the app using:

NODE_ENV=production node app.js

or setting the correct environment with forever or pm2

Forever:

NODE_ENV=production forever [flags] start app.js [app_flags]

PM2 (via shell):

export NODE_ENV=staging
pm2 start app.js

PM2 (via .json):

process.json

{
   "apps" : [{
    "name": "My App",
    "script": "worker.js",
    "env": {
      "NODE_ENV": "development",
    },
    "env_production" : {
       "NODE_ENV": "production"
    }
  }]
}

And then

$ pm2 start process.json --env production

This solution is very clean and it makes easy set different config files for Production/Staging/Development environment and for local setting too.

Check out yowsup
https://github.com/tgalal/yowsup

Yowsup is a python library that allows you to do all the previous in your own app. Yowsup allows you to login and use the Whatsapp service and provides you with all capabilities of an official Whatsapp client, allowing you to create a full-fledged custom Whatsapp client.

A solid example of Yowsup's usage is Wazapp. Wazapp is full featured Whatsapp client that is being used by hundreds of thousands of people around the world. Yowsup is born out of the Wazapp project. Before becoming a separate project, it was only the engine powering Wazapp. Now that it matured enough, it was separated into a separate project, allowing anyone to build their own Whatsapp client on top of it. Having such a popular client as Wazapp, built on Yowsup, helped bring the project into a much advanced, stable and mature level, and ensures its continuous development and maintaince.

Yowsup also comes with a cross platform command-line frontend called yowsup-cli. yowsup-cli allows you to jump into connecting and using Whatsapp service directly from command line.

The following code does what is required

function doTest() {
  SpreadsheetApp.getActiveSheet().getRange('F2').setValue('Hello');
}

You could do this by simply extending the boolean prototype

Boolean.prototype.intval = function(){return ~~this}

It is not too easy to understand what is going on there so an alternate version would be

Boolean.prototype.intval = function(){return (this == true)?1:0}

having done which you can do stuff like

document.write(true.intval());

When I use booleans to store conditions I often convert them to bitfields in which case I end up using an extended version of the prototype function

Boolean.prototype.intval = function(places)
{
 places = ('undefined' == typeof(places))?0:places; 
 return (~~this) << places
}

with which you can do

document.write(true.intval(2))

which produces 4 as its output.

Replace false with 0

It's been a while since this was posted but I found a more elegant solution if you are not needing to support old browsers.

You can do a check with

performance.navigation.type

Documentation including browser support is here: https://developer.mozilla.org/en-US/docs/Web/API/Performance/navigation

So to see if the page was loaded from history using back you can do

if(performance.navigation.type == 2){
   location.reload(true);
}

The 2 indicates the page was accessed by navigating into the history. Other possibilities are-

0:The page was accessed by following a link, a bookmark, a form submission, or a script, or by typing the URL in the address bar.

1:The page was accessed by clicking the Reload button or via the Location.reload() method.

255: Any other way

These are detailed here: https://developer.mozilla.org/en-US/docs/Web/API/PerformanceNavigation

Note Performance.navigation.type is now deprecated in favour of PerformanceNavigationTiming.type which returns 'navigate' / 'reload' / 'back_forward' / 'prerender': https://developer.mozilla.org/en-US/docs/Web/API/PerformanceNavigationTiming/type

I've seen many answers with many votes advocating using the ternary operator. The ternary is great if a) you do have an alternative option and b) you are returning a fairly simple value from a simple condition. But...

The original question didn't have an alternative, and the ternary operator with only a single (real) branch forces you to return a confected answer.

lemons ? "foo gave me a bar" : "who knows what you'll get back"

I think the most common variation is lemons ? 'foo...' : '', and, as you'll know from reading the myriad of articles for any language on true, false, truthy, falsey, null, nil, blank, empty (with our without ?) , you are entering a minefield (albeit a well documented minefield.)

As soon as any part of the ternary gets complicated you are better off with a more explicit form of conditional.

A long way to say that I am voting for if (lemons) "foo".

thisReader.GetString(int columnIndex)

let formFields     = form.querySelectorAll(`input:not([type='hidden']), select`)

ES6 version that has the advantage of ignoring the hidden fields if that is what you want

(This was written based on the original version of the question.)

I want to create a empty list (or whatever is the best way) can hold 10 elements.

All lists can hold as many elements as you like, subject only to the limit of available memory. The only "size" of a list that matters is the number of elements currently in it.

but when I run it, the result is []

print display s1 is not valid syntax; based on your description of what you're seeing, I assume you meant display(s1) and then print s1. For that to run, you must have previously defined a global s1 to pass into the function.

Calling display does not modify the list you pass in, as written. Your code says "s1 is a name for whatever thing was passed in to the function; ok, now the first thing we'll do is forget about that thing completely, and let s1 start referring instead to a newly created list. Now we'll modify that list". This has no effect on the value you passed in.

There is no reason to pass in a value here. (There is no real reason to create a function, either, but that's beside the point.) You want to "create" something, so that is the output of your function. No information is required to create the thing you describe, so don't pass any information in. To get information out, return it.

That would give you something like:

def display():
    s1 = list();
    for i in range(0, 9):
        s1[i] = i
    return s1

The next problem you will note is that your list will actually have only 9 elements, because the end point is skipped by the range function. (As side notes, [] works just as well as list(), the semicolon is unnecessary, s1 is a poor name for the variable, and only one parameter is needed for range if you're starting from 0.) So then you end up with

def create_list():
    result = list()
    for i in range(10):
        result[i] = i
    return result

However, this is still missing the mark; range is not some magical keyword that's part of the language the way for and def are, but instead it's a function. And guess what that function returns? That's right - a list of those integers. So the entire function collapses to

def create_list():
    return range(10)

and now you see why we don't need to write a function ourselves at all; range is already the function we're looking for. Although, again, there is no need or reason to "pre-size" the list.

Here is how I did it:

START=$(date +%s);
sleep 1; # Your stuff
END=$(date +%s);
echo $((END-START)) | awk '{print int($1/60)":"int($1%60)}'

Really simple, take the number of seconds at the start, then take the number of seconds at the end, and print the difference in minutes:seconds.

Updated:

As pointed out in the comments, setting the description to null indicates that the image is purely decorative and is understood as that by screen readers like TalkBack.

Old answer, I no longer support this answer:

For all the people looking how to avoid the warning:

I don't think android:contentDescription="@null" is the best solution.

I'm using tools:ignore="ContentDescription" that is what is meant to be.

Make sure you include xmlns:tools="http://schemas.android.com/tools" in your root layout.

Does it support

<!DOCTYPE html>

Yes it does.

Perhaps a better question is what modern web features IE8 supports. Some of the best places to answer that are caniuse.com, html5test.com, and browserscope.org.

HTML5 means a lot of different things to different people. These days, it means HTML, CSS, and JavaScript functionality. The term is becoming a bit "Web 2.0"-like.

MessageBox.Show also returns a DialogResult, which if you put some buttons on there, means you can have it returned what the user clicked. Most of the time I write something like

if (MessageBox.Show("Do you want to continue?", "Question", MessageBoxButtons.YesNo) == MessageBoxResult.Yes) {
     //some interesting behaviour here
}

which I guess is a bit unwieldy but it gets the job done.

git merge --abort

An array isn't immutable by nature; you can't make it constant.

The nearest you can get is:

var letter_goodness = [...]float32 {.0817, .0149, .0278, .0425, .1270, .0223, .0202, .0609, .0697, .0015, .0077, .0402, .0241, .0675, .0751, .0193, .0009, .0599, .0633, .0906, .0276, .0098, .0236, .0015, .0197, .0007 }

Note the [...] instead of []: it ensures you get a (fixed size) array instead of a slice. So the values aren't fixed but the size is.

You are trying to use the wrong interface type. The type Function is not appropriate in this case because it receives a parameter and has a return value. Instead you should use Consumer (formerly known as Block)

The Function type is declared as

interface Function<T,R> {
  R apply(T t);
}

However, the Consumer type is compatible with that you are looking for:

interface Consumer<T> {
   void accept(T t);
}

As such, Consumer is compatible with methods that receive a T and return nothing (void). And this is what you want.

For instance, if I wanted to display all element in a list I could simply create a consumer for that with a lambda expression:

List<String> allJedi = asList("Luke","Obiwan","Quigon");
allJedi.forEach( jedi -> System.out.println(jedi) );

You can see above that in this case, the lambda expression receives a parameter and has no return value.

Now, if I wanted to use a method reference instead of a lambda expression to create a consume of this type, then I need a method that receives a String and returns void, right?.

I could use different types of method references, but in this case let's take advantage of an object method reference by using the println method in the System.out object, like this:

Consumer<String> block = System.out::println

Or I could simply do

allJedi.forEach(System.out::println);

The println method is appropriate because it receives a value and has a return type void, just like the accept method in Consumer.

So, in your code, you need to change your method signature to somewhat like:

public static void myForEach(List<Integer> list, Consumer<Integer> myBlock) {
   list.forEach(myBlock);
}

And then you should be able to create a consumer, using a static method reference, in your case by doing:

myForEach(theList, Test::displayInt);

Ultimately, you could even get rid of your myForEach method altogether and simply do:

theList.forEach(Test::displayInt);

About Functions as First Class Citizens

All been said, the truth is that Java 8 will not have functions as first-class citizens since a structural function type will not be added to the language. Java will simply offer an alternative way to create implementations of functional interfaces out of lambda expressions and method references. Ultimately lambda expressions and method references will be bound to object references, therefore all we have is objects as first-class citizens. The important thing is the functionality is there since we can pass objects as parameters, bound them to variable references and return them as values from other methods, then they pretty much serve a similar purpose.

According to this post, you should enable it in XCode.

Variables in make can come from the environment in which make is run. Every environment variable that make sees when it starts up is transformed into a make variable with the same name and value. However, an explicit assignment in the makefile, or with a command argument, overrides the environment. (If the ‘-e’ flag is specified, then values from the environment override assignments in the makefile.

info diff then select: Output formats -> Context -> Unified format -> Detailed Unified :

Or online man diff on gnu following the same path to the same section:

File: diff.info, Node: Detailed Unified, Next: Example Unified, Up: Unified Format

Detailed Description of Unified Format ......................................

The unified output format starts with a two-line header, which looks like this:

 --- FROM-FILE FROM-FILE-MODIFICATION-TIME
 +++ TO-FILE TO-FILE-MODIFICATION-TIME

The time stamp looks like `2002-02-21 23:30:39.942229878 -0800' to indicate the date, time with fractional seconds, and time zone.

You can change the header's content with the `--label=LABEL' option; see *Note Alternate Names::.

Next come one or more hunks of differences; each hunk shows one area where the files differ. Unified format hunks look like this:

 @@ FROM-FILE-RANGE TO-FILE-RANGE @@
  LINE-FROM-EITHER-FILE
  LINE-FROM-EITHER-FILE...

The lines common to both files begin with a space character. The lines that actually differ between the two files have one of the following indicator characters in the left print column:

`+' A line was added here to the first file.

`-' A line was removed here from the first file.

The following code should display the time detla...

from datetime import datetime

tstart = datetime.now()

# code to speed test

tend = datetime.now()
print tend - tstart

When you create an initialization of the ResourceBundle, you can do this way also.

For testing and development I have created a properties file under \src with the name prp.properties.

Use this way:

ResourceBundle rb = ResourceBundle.getBundle("prp");

Naming convention and stuff:

With Kotlin it is even easier:

val file = File(uri.path)

Or if you are using Kotlin extensions for Android:

val file = uri.toFile()

A complex filter condition is better in performance perspective, but the best performance will show old fashion for loop with a standard if clause is the best option. The difference on a small array 10 elements difference might ~ 2 times, for a large array the difference is not that big.
You can take a look on my GitHub project, where I did performance tests for multiple array iteration options

For small array 10 element throughput ops/s: For medium 10,000 elements throughput ops/s: For large array 1,000,000 elements throughput ops/s:

NOTE: tests runs on

• 8 CPU
• 1 GB RAM
• OS version: 16.04.1 LTS (Xenial Xerus)
• java version: 1.8.0_121
• jvm: -XX:+UseG1GC -server -Xmx1024m -Xms1024m

UPDATE: Java 11 has some progress on the performance, but the dynamics stay the same

Benchmark mode: Throughput, ops/time

If you have the source arrays in an array itself you can use SelectMany:

var arrays = new[]{new[]{1, 2, 3}, new[]{4, 5, 6}};
var combined = arrays.SelectMany(a => a).ToArray();
foreach (var v in combined) Console.WriteLine(v);   

gives

1
2
3
4
5
6

Probably this is not the fastest method but might fit depending on usecase.

Extending User1648825's nice simple answer (I can't comment and my edit was rejected):

@Value("${spring.profiles.active}")
private String activeProfile;

This may throw an IllegalArgumentException if no profiles are set (I get a null value). This may be a Good Thing if you need it to be set; if not use the 'default' syntax for @Value, ie:

@Value("${spring.profiles.active:Unknown}")
private String activeProfile;

...activeProfile now contains 'Unknown' if spring.profiles.active could not be resolved

If you don't care about the type of the numbers you can simply use:

qs[0].values()

window.location adds an item to your history in that you can (or should be able to) click "Back" and go back to the current page.

window.location.replace replaces the current history item so you can't go back to it.

See window.location:

assign(url): Load the document at the provided URL.

replace(url):Replace the current document with the one at the provided URL. The difference from the assign() method is that after using replace() the current page will not be saved in session history, meaning the user won't be able to use the Back button to navigate to it.

Oh and generally speaking:

window.location.href = url;

is favoured over:

window.location = url;

This is a base service class (ServiceBase subclass) that can be subclassed to build a windows service that can be easily installed from the command line, without installutil.exe. This solution is derived from How to make a .NET Windows Service start right after the installation?, adding some code to get the service Type using the calling StackFrame

public abstract class InstallableServiceBase:ServiceBase

            foreach (StackFrame x in frames)
            {
                ret = x.GetMethod();

                Type t1 = ret.DeclaringType;

All you have to do is to implement two public/internal methods in your real service:

    new internal  void InstallService()
    {
        base.InstallService();
    }
    new internal void UninstallService()
    {
        base.UninstallService();
    }

and then call them when you want to install the service:

    static void Main(string[] args)
    {
        if (Environment.UserInteractive)
        {
            MyService s1 = new MyService();
            if (args.Length == 1)
            {
                switch (args[0])
                {
                    case "-install":
                        s1.InstallService();

                        break;
                    case "-uninstall":

                        s1.UninstallService();
                        break;
                    default:
                        throw new NotImplementedException();
                }
            }


        }
        else {
            ServiceBase[] ServicesToRun;
            ServicesToRun = new ServiceBase[] 
            { 
                new MyService() 
            };
            ServiceBase.Run(MyService);            
        }

    }

 updateTypeahead(this)

will not pass DOM element to the function updateTypeahead(this). Here this will refer to the scope. If you want to access the DOM element use updateTypeahead($event). In the callback function you can get the DOM element by event.target.

Please Note : ng-change function doesn't allow to pass $event as variable.

The answer to this is very needed today because not everyone wants to use cURL to consume web services. Also PHP does allow for this using the following code

function get_info()
{
    $post_data = array(
        'test' => 'foobar',
        'okay' => 'yes',
        'number' => 2
    );

    // Send a request to example.com
    $result = $this->post_request('http://www.example.com/', $post_data);

    if ($result['status'] == 'ok'){

        // Print headers
        echo $result['header'];

        echo '<hr />';

        // print the result of the whole request:
        echo $result['content'];

    }
    else {
        echo 'A error occured: ' . $result['error'];
    }

}

function post_request($url, $data, $referer='') {

    // Convert the data array into URL Parameters like a=b&foo=bar etc.
    $data = http_build_query($data);

    // parse the given URL
    $url = parse_url($url);

    if ($url['scheme'] != 'http') {
        die('Error: Only HTTP request are supported !');
    }

    // extract host and path:
    $host = $url['host'];
    $path = $url['path'];

    // open a socket connection on port 80 - timeout: 30 sec
    $fp = fsockopen($host, 80, $errno, $errstr, 30);

    if ($fp){

        // send the request headers:
        fputs($fp, "POST $path HTTP/1.1\r\n");
        fputs($fp, "Host: $host\r\n");

        if ($referer != '')
            fputs($fp, "Referer: $referer\r\n");

        fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
        fputs($fp, "Content-length: ". strlen($data) ."\r\n");
        fputs($fp, "Connection: close\r\n\r\n");
        fputs($fp, $data);

        $result = '';
        while(!feof($fp)) {
            // receive the results of the request
            $result .= fgets($fp, 128);
        }
    }
    else {
        return array(
            'status' => 'err',
            'error' => "$errstr ($errno)"
        );
    }

    // close the socket connection:
    fclose($fp);

    // split the result header from the content
    $result = explode("\r\n\r\n", $result, 2);

    $header = isset($result[0]) ? $result[0] : '';
    $content = isset($result[1]) ? $result[1] : '';

    // return as structured array:
    return array(
        'status' => 'ok',
        'header' => $header,
        'content' => $content);

The Form has two properties called MinimizeBox and MaximizeBox, set both of them to false.

To stop the form closing, handle the FormClosing event, and set e.Cancel = true; in there and after that, set WindowState = FormWindowState.Minimized;, to minimize the form.

In the Unix world, there were a few possible arrangements for the sizes of integers and pointers for 64-bit platforms. The two mostly widely used were ILP64 (actually, only a very few examples of this; Cray was one such) and LP64 (for almost everything else). The acronynms come from 'int, long, pointers are 64-bit' and 'long, pointers are 64-bit'.

Type           ILP64   LP64   LLP64
char              8      8       8
short            16     16      16
int              64     32      32
long             64     64      32
long long        64     64      64
pointer          64     64      64

The ILP64 system was abandoned in favour of LP64 (that is, almost all later entrants used LP64, based on the recommendations of the Aspen group; only systems with a long heritage of 64-bit operation use a different scheme). All modern 64-bit Unix systems use LP64. MacOS X and Linux are both modern 64-bit systems.

Microsoft uses a different scheme for transitioning to 64-bit: LLP64 ('long long, pointers are 64-bit'). This has the merit of meaning that 32-bit software can be recompiled without change. It has the demerit of being different from what everyone else does, and also requires code to be revised to exploit 64-bit capacities. There always was revision necessary; it was just a different set of revisions from the ones needed on Unix platforms.

If you design your software around platform-neutral integer type names, probably using the C99 <inttypes.h> header, which, when the types are available on the platform, provides, in signed (listed) and unsigned (not listed; prefix with 'u'):

• int8_t - 8-bit integers
• int16_t - 16-bit integers
• int32_t - 32-bit integers
• int64_t - 64-bit integers
• uintptr_t - unsigned integers big enough to hold pointers
• intmax_t - biggest size of integer on the platform (might be larger than int64_t)

You can then code your application using these types where it matters, and being very careful with system types (which might be different). There is an intptr_t type - a signed integer type for holding pointers; you should plan on not using it, or only using it as the result of a subtraction of two uintptr_t values (ptrdiff_t).

But, as the question points out (in disbelief), there are different systems for the sizes of the integer data types on 64-bit machines. Get used to it; the world isn't going to change.

Maybe a better question would be to ask why do these operators exist in C. K&R calls increment and decrement operators 'unusual' (Section 2.8page 46). The Introduction calls them 'more concise and often more efficient'. I suspect that the fact that these operations always come up in pointer manipulation also has played a part in their introduction. In Python it has been probably decided that it made no sense to try to optimise increments (in fact I just did a test in C, and it seems that the gcc-generated assembly uses addl instead of incl in both cases) and there is no pointer arithmetic; so it would have been just One More Way to Do It and we know Python loathes that.

ForEach can also be Chained, just put back to the pileline after the action. remain fluent

Employees.ForEach(e=>e.Act_A)
         .ForEach(e=>e.Act_B)
         .ForEach(e=>e.Act_C);

Orders  //just for demo
    .ForEach(o=> o.EmailBuyer() )
    .ForEach(o=> o.ProcessBilling() )
    .ForEach(o=> o.ProcessShipping());


//conditional
Employees
    .ForEach(e=> {  if(e.Salary<1000) e.Raise(0.10);})
    .ForEach(e=> {  if(e.Age   >70  ) e.Retire();});

An Eager version of implementation.

public static IEnumerable<T> ForEach<T>(this IEnumerable<T> enu, Action<T> action)
{
    foreach (T item in enu) action(item);
    return enu; // make action Chainable/Fluent
}

Edit: a Lazy version is using yield return, like this.

public static IEnumerable<T> ForEachLazy<T>(this IEnumerable<T> enu, Action<T> action)
{
    foreach (var item in enu)
    {
        action(item);
        yield return item;
    }
}

The Lazy version NEEDs to be materialized, ToList() for example, otherwise, nothing happens. see below great comments from ToolmakerSteve.

IQueryable<Product> query = Products.Where(...);
query.ForEachLazy(t => t.Price = t.Price + 1.00)
    .ToList(); //without this line, below SubmitChanges() does nothing.
SubmitChanges();

I keep both ForEach() and ForEachLazy() in my library.

def ipcheck():
# 1.Validate the ip adderess
input_ip = input('Enter the ip:')
flag = 0

pattern = "^\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}$"
match = re.match(pattern, input_ip)
if (match):
    field = input_ip.split(".")
    for i in range(0, len(field)):
        if (int(field[i]) < 256):
            flag += 1
        else:
            flag = 0
if (flag == 4):
    print("valid ip")
else:
    print('No match for ip or not a valid ip')

Use Code:

var startDate = "2019-03-12"; //Date Format YYYY-MM-DD

$('#datepicker').val(startDate).datepicker("update");

Explanation:

Datepicker(input field) Selector #datepicker.

Update input field.

Call datepicker with option update.

If you need to make a comparison between a class and a known type, for example:

class Example{};
...
Example eg = Example();

You can use this comparison line:

bool isType = string( typeid(eg).name() ).find("Example") != string::npos;

which checks the typeid name contains the string type (the typeid name has other mangled data, so its best to do a s1.find(s2) instead of ==).

For better performance you should use:

var numItems = $('div.item').length;

Since it will only look for the div elements in DOM and will be quick.

Suggestion: using size() instead of length property means one extra step in the processing since SIZE() uses length property in the function definition and returns the result.

The libraries mentioned in other answers would be fine solutions, but if you already happen to be digging through real-world html in your project, the Jsoup project has a lot more to offer than just managing "ampersand pound FFFF semicolon" things.

// textValue: <p>This is a&nbsp;sample. \"Granny\" Smith &#8211;.<\/p>\r\n
// becomes this: This is a sample. "Granny" Smith –.
// with one line of code:
// Jsoup.parse(textValue).getText(); // for older versions of Jsoup
Jsoup.parse(textValue).text();

// Another possibility may be the static unescapeEntities method:
boolean strictMode = true;
String unescapedString = org.jsoup.parser.Parser.unescapeEntities(textValue, strictMode);

And you also get the convenient API for extracting and manipulating data, using the best of DOM, CSS, and jquery-like methods. It's open source and MIT licence.

I know this is a really old question but I wanted to add a bit of explanation that I discovered the hard way (this is n00b information).

"Basic Authentication" shares the same accounts that you have on your local computer or network. If you leave the domain and realm empty, local accounts are what are actually being used. So to add a new account you follow the exact process you would for adding a normal new user account to your local computer (as answered by JoshM or shown here). If you enter a domain and realm you can create network accounts in your local active directory and these are what will be used to log the user in and out.

Because it has been around for so long, basic authentication is generally compatible with any browser/system out there but it does have to major flaws:

• user and password are sent in the clear (except over SSL)
• you need to have a user account for each user or client

For more information about basic authentication or user accounts see the following MSDN page.

strip only strips characters from the very front and back of the string.

To delete a list of characters, you could use the string's translate method:

import string
name = "Barack (of Washington)"
table = string.maketrans( '', '', )
print name.translate(table,"(){}<>")
# Barack of Washington

This should work to get a specific column out of the command output "docker images":

This is going to print the third column

For IE

If you are using IE then go to print preview ( right click on document -> print preview ), go to settings and there is option "print background color and images", select that option and try.

MySql decimal types are a little bit more complicated than just left-of and right-of the decimal point.

The first argument is precision, which is the number of total digits. The second argument is scale which is the maximum number of digits to the right of the decimal point.

Thus, (4,2) can be anything from -99.99 to 99.99.

As for why you're getting 99.99 instead of the desired 3.80, the value you're inserting must be interpreted as larger than 99.99, so the max value is used. Maybe you could post the code that you are using to insert or update the table.

Edit

Corrected a misunderstanding of the usage of scale and precision, per http://dev.mysql.com/doc/refman/5.0/en/numeric-types.html.

If you have a datetime column in excel file. Then below code will fix it. I went through a lot of answers on StackOverflow and nothing fixed it. I thought file is corrupted.

from datetime import datetime
jsts = 1468629431.0
datetime.fromtimestamp(jsts) 

The size of an array is static in C++. You cannot dynamically resize it. That's what std::vector is for:

std::vector<int> v; // size of the vector starts at 0

v.push_back(10); // v now has 1 element
v.push_back(20); // v now has 2 elements
v.push_back(30); // v now has 3 elements

v.pop_back(); // removes the 30 and resizes v to 2

v.resize(v.size() - 1); // resizes v to 1

I just solve this error by waiting element display property

waitFor() { element.displayed }

There is a conflict between Visual Studio 2015 and Visual Studio Code for the git credentials. When i changed my credentials on VS 2015 VS Code let me push with the correct git ID.

Override getResources() in Activity.

Set TextView's size in sp as usual like android:textSize="32sp"

override fun getResources(): Resources {
    return super.getResources().apply {
        configuration.fontScale = 1F
        updateConfiguration(configuration, displayMetrics)
    }
}

I'll take a stab at it:

/^[a-z](?:_?[a-z0-9]+)*$/i

Explained:

/
 ^           # match beginning of string
 [a-z]       # match a letter for the first char
 (?:         # start non-capture group
   _?          # match 0 or 1 '_'
   [a-z0-9]+   # match a letter or number, 1 or more times
 )*          # end non-capture group, match whole group 0 or more times
 $           # match end of string
/i           # case insensitive flag

The non-capture group takes care of a) not allowing two _'s (it forces at least one letter or number per group) and b) only allowing the last char to be a letter or number.

Some test strings:

"a": match
"_": fail
"zz": match
"a0": match
"A_": fail
"a0_b": match
"a__b": fail
"a_1_c": match

System.Uri.GetComponents, just specified components you want.

Uri uri = new Uri("http://www.example.com/mypage.aspx?myvalue1=hello&myvalue2=goodbye");
uri.GetComponents(UriComponents.SchemeAndServer | UriComponents.Path, UriFormat.UriEscaped);

Output:

http://www.example.com/mypage.aspx

Please try the below XAML snippet:

<Button Width="300" Height="50">
  <StackPanel Orientation="Horizontal">
    <Image Source="Pictures/img.jpg" Width="20" Height="20"/>
    <TextBlock Text="Blablabla" VerticalAlignment="Center" />
  </StackPanel>
</Button>

In XAML elements are in a tree structure. So you have to add the child control to its parent control. The below code snippet also works fine. Give a name for your XAML root grid as 'MainGrid'.

Image img = new Image();
img.Source = new BitmapImage(new Uri(@"foo.png"));

StackPanel stackPnl = new StackPanel();
stackPnl.Orientation = Orientation.Horizontal;
stackPnl.Margin = new Thickness(10);
stackPnl.Children.Add(img);

Button btn = new Button();
btn.Content = stackPnl;
MainGrid.Children.Add(btn);

the query() method can do that very intuitively. Express your condition in a string to be evaluated like the following example :

df = df.query("columnNameA <= @x or columnNameB == @y")

with x and y are declared variables which you can refer to with @

You can load the whole *.dll assembly with

$Assembly = [System.Reflection.Assembly]::LoadFrom("C:\folder\file.dll");

Who "they"? I don't think there's a visible attribute in html.

If you use the Angular CLI to create your components, let's say CarComponent, it attaches app to the selector name (i.e app-car) and this throws the above error when you reference the component in the parent view. Therefore you either have to change the selector name in the parent view to let's say <app-car></app-car> or change the selector in the CarComponent to selector: 'car'

May be this could help

    <script type="text/javascript" language="javascript">

This was close to working for me. Also had to add:

"changeOrigin": true,
"pathRewrite": {"^/proxy" : ""}

Full proxy.conf.json shown below:

{
    "/proxy/*": {
        "target": "https://url.com",
        "secure": false,
        "changeOrigin": true,
        "logLevel": "debug",
        "pathRewrite": {
            "^/proxy": ""
        }
    }
}

I am assuming that you need the JDK itself. If so you can accomplish this with:

sudo add-apt-repository ppa:sun-java-community-team/sun-java6

sudo apt-get update

sudo apt-get install sun-java6-jdk

You don't really need to go around editing sources or anything along those lines.

With numpy :

im = Image.open('image.gif')
im_matrix = np.array(im)
print(im_matrix[0][0])

Give RGB vector of the pixel in position (0,0)

First Check your version code and version name if you are updating your app. And make sure you have a previous keystore.

If you are updating app then follow step 1,3,4.

Step 1:

Goto your cordova project for generate our release build:

D:\projects\Phonegap\Example> cordova build --release android

Then, we can find our unsigned APK file in platforms/android/ant-build. In our example, the file was

if u used ant-build

yourproject/platforms/android/ant-build/Example-release-unsigned.apk

OR

if u used gradle-build

yourProject/platforms/android/build/outputs/apk/Example-release-unsigned.apk

Step 2:

Key Generation:

Syntax:

keytool -genkey -v -keystore <keystoreName>.keystore -alias <Keystore AliasName> -keyalg <Key algorithm> -keysize <Key size> -validity <Key Validity in Days>

if keytool command not recognize do this step

Check that the directory the keytool executable is in is on your path. (For example, on my Windows 7 machine, it's in C:\Program Files (x86)\Java\jre6\bin.)

Example:

keytool -genkey -v -keystore NAME-mobileapps.keystore -alias NAMEmobileapps -keyalg RSA -keysize 2048 -validity 10000


keystore password? : xxxxxxx
What is your first and last name? :  xxxxxx
What is the name of your organizational unit? :  xxxxxxxx
What is the name of your organization? :  xxxxxxxxx
What is the name of your City or Locality? :  xxxxxxx
What is the name of your State or Province? :  xxxxx
What is the two-letter country code for this unit? :  xxx

Then the Key store has been generated with name as NAME-mobileapps.keystore

Step 3:

Place the generated keystore in D:\projects\Phonegap\Example\platforms\android\ant-build

To sign the unsigned APK, run the jarsigner tool which is also included in the JDK:

Syntax:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore <keystorename <Unsigned APK file> <Keystore Alias name>

If it doesn't reconize do these steps

(1) Right click on "This PC" > right-click Properties > Advanced system settings > Environment Variables > select PATH then EDIT.

(2) Add your jdk bin folder path to environment variables, it should look like this:

"C:\Program Files\Java\jdk1.8.0_40\bin".

Example:

D:\projects\Phonegap\Example\platforms\android\ant-build> jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore NAME-mobileapps.keystore Example-release-unsigned.apk xxxxxmobileapps

Enter KeyPhrase as 'xxxxxxxx'

This signs the apk in place.

Step 4:

Finally, we need to run the zip align tool to optimize the APK:

if zipalign not recognize then

(1) goto your android sdk path and find zipalign it is usually in android-sdk\build-tools\23.0.3

(2) Copy zipalign file paste into your generate release apk folder usually in below path

yourproject/platforms/android/ant-build/Example-release-unsigned.apk

D:\projects\Phonegap\Example\platforms\android\ant-build> zipalign -v 4 Example-release-unsigned.apk Example.apk 

OR

D:\projects\Phonegap\Example\platforms\android\ant-build> C:\Phonegap\adt-bundle-windows-x86_64-20140624\sdk\build-tools\android-4.4W\zipalign -v 4 Example-release-unsigned.apk Example.apk

Now we have our final release binary called example.apk and we can release this on the Google Play Store.

@boernard 's answer solves this from the Android Studio IDE, but if you want to understand what's happening under the covers, it's a simple gradle build file update:

You can edit the build.gradle file from within the IDE (left pane: Gradle Scripts -> build.gradle (Module: app)) or use the raw path (<proj_dir>/app/build.gradle) and add/update the following dependency section:

dependencies {
    //
    // IDE setting pulls in the specific version of v4 support you have installed:
    //
    //compile 'com.android.support:support-v4:21.0.3'

    //
    // generic directive pulls in any available version of v4 support:
    //
    compile 'com.android.support:support-v4:+'
}

Using the above generic compile directive, allows you to ship your code to anyone, provided they have some level of the Android Support Libraries v4 installed.

if all your value are positive, you can do -max(-n)

try:
      doSomething()
except Exception: 
    pass
else:
      stuffDoneIf()
      TryClauseSucceeds()

FYI the else clause can go after all exceptions and will only be run if the code in the try doesn't cause an exception.

Just use ||

if (A || B) { your action here }

Note: with string and number. It's more complicated.

Check this for deep understading:

Inside Controller Action you can access HttpContext.Response. There you can set the response status as in the following listing.

[HttpPost]
public ActionResult PostViaAjax()
{
    var body = Request.BinaryRead(Request.TotalBytes);

    var result = Content(JsonError(new Dictionary<string, string>()
    {
        {"err", "Some error!"}
    }), "application/json; charset=utf-8");
    HttpContext.Response.StatusCode = (int)HttpStatusCode.BadRequest;
    return result;
}

In very simple terms, I like to think about it like this:

• real is the actual amount of time it took to run the command (as if you had timed it with a stopwatch)

• user and sys are how much 'work' the CPU had to do to execute the command. This 'work' is expressed in units of time.

Generally speaking:

• user is how much work the CPU did to run to run the command's code
• sys is how much work the CPU had to do to handle 'system overhead' type tasks (such as allocating memory, file I/O, ect.) in order to support the running command

Since these last two times are counting 'work' done, they don't include time a thread might have spent waiting (such as waiting on another process or for disk I/O to finish).

real, however, is a measure of actual runtime and not 'work', so it does include any time spent waiting.

Have you taken a look at put.py? I've used it in the past. You can also just hack up your own request with urllib.

class Pair<T1, T2> {
    private key: T1;
    private value: T2;

    constructor(key: T1, value: T2) {
        this.key = key;
        this.value = value;
    }

    getKey() {
        return this.key;
    }

    getValue() {
        return this.value;
    }
}
const myPair = new Pair<string, number>('test', 123);
console.log(myPair.getKey(), myPair.getValue());

I faced this issue because my web page was zoomed out to 90% and as I was viewing my page in responsive mode through the browser developer tools, I did not notice it right away.

You must use the following:

NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *dateComponents = [gregorian components:(NSHourCalendarUnit  | NSMinuteCalendarUnit | NSSecondCalendarUnit) fromDate:yourDateHere];
NSInteger hour = [dateComponents hour];
NSInteger minute = [dateComponents minute];
NSInteger second = [dateComponents second];
[gregorian release];

There is no difference between NSDate* now and NSDate *now, it's just a matter of preference. From the compiler perspective, nothing changes.

To get Consumer Key & Consumer Secret, you have to create an app in Twitter via

https://developer.twitter.com/en/apps

Then you'll be taken to a page containing Consumer Key & Consumer Secret.

Hopefully this information will clarify OAuth essentials for Twitter:

1. Create a Twitter account if you don't already have one
2. Visit 'https://apps.twitter.com' and follow the required prompts to create a developer project (Twitter requires you to answer some questions before they will approve your account. Approval was nearly instant in my case.)
3. Requesting the API key and secret via the Developer Portal causes Twitter to produce the following three things:

• API key (this is your 'consumer key')
• API secret key (this is your 'consumer secret')
• Bearer token

4. Next, visit the 'Authentication Tokens' area of the Developer Portal and generate an 'Access token & secret'. This will provide you with the following two items:

• Access token (this is your 'token key')
• Access token secret (this is your 'token secret')

5. The consumer key, consumer secret, token key, and token secret should be sufficient to do Twitter API calls (they were for me). Good luck!

Here it is nice and simple.

root = tkinter.Tk()
root.title('My Title')

root is the window you create and root.title() sets the title of that window.

The output of head -10 file can be piped to grep in order to accomplish this:

head -10 file | grep …

Using Perl:

perl -ne 'last if $. > 10; print if /pattern/' file

On windows use the name of the table in quotes: TABLE "user"; or SELECT * FROM "user";

Plain ansible_default_ipv4.address might not be what you think in some cases, use:

ansible_default_ipv4.address|default(ansible_all_ipv4_addresses[0])

Right now, you're creating an instance of every type defined in the assembly. You only need to create a single instance of Class1 in order to call the method:

class Program
{
    static void Main(string[] args)
    {
        var DLL = Assembly.LoadFile(@"C:\visual studio 2012\Projects\ConsoleApplication1\ConsoleApplication1\DLL.dll");

        var theType = DLL.GetType("DLL.Class1");
        var c = Activator.CreateInstance(theType);
        var method = theType.GetMethod("Output");
        method.Invoke(c, new object[]{@"Hello"});

        Console.ReadLine();
    }
}

I have used a trick to handle the apostrophe special character. When replacing ' for \' you need to place four backslashes before the apostrophe.

str.replaceAll("'","\\\\'");

If you wants display anchors in your own choice of colors than you should define the color in anchor tag property in CSS like this:-

a { text-decoration: none; color:red; }
a:visited { text-decoration: none; }
a:hover { text-decoration: none; }
a:focus { text-decoration: none; }
a:hover, a:active { text-decoration: none; }

see the demo:- http://jsfiddle.net/zSWbD/7/

The usual method I have seen is X.Y.Z, which generally corresponds to major.minor.patch:

• Major version numbers change whenever there is some significant change being introduced. For example, a large or potentially backward-incompatible change to a software package.
• Minor version numbers change when a new, minor feature is introduced or when a set of smaller features is rolled out.
• Patch numbers change when a new build of the software is released to customers. This is normally for small bug-fixes or the like.

Other variations use build numbers as an additional identifier. So you may have a large number for X.Y.Z.build if you have many revisions that are tested between releases. I use a couple of packages that are identified by year/month or year/release. Thus, a release in the month of September of 2010 might be 2010.9 or 2010.3 for the 3rd release of this year.

There are many variants to versioning. It all boils down to personal preference.

For the "1.3v1.1", that may be two different internal products, something that would be a shared library / codebase that is rev'd differently from the main product; that may indicate version 1.3 for the main product, and version 1.1 of the internal library / package.

Nope, they are not equivalent.

With myObj = 1; you are using a global variable.

The latter declaration create a variable local to the scope you are using.

Try the following code to understand the differences:

external = 5;
function firsttry() {
  var external = 6;
  alert("first Try: " + external);
}

function secondtry() {
  external = 7;
  alert("second Try: " + external);
}

alert(external); // Prints 5
firsttry(); // Prints 6
alert(external); // Prints 5
secondtry(); // Prints 7
alert(external); // Prints 7

The second function alters the value of the global variable "external", but the first function doesn't.

This should work. Your code works for me, like for Tamás and Manoj Govindan. It looks like you could try to update Matplotlib. If you can't update Matplotlib (for instance if you have insufficient administrative rights), maybe using a different backend with matplotlib.use() could help.

Found one of the reasons which causes this problem

When we try to use any

string,style,color,etc,

in manifest file that is not present in values (string.xml,style.xml,color.xml,etc,) then this type of error occurs

use "x".ord for a single character or "xyz".sum for a whole string.

if [ !-d $dirName ];then
     if ! mkdir $dirName; then  # Shorter version. Shell will complain if you put braces here though
     echo "Can't make dir: $dirName"
     fi
fi

When Object variables are initially used in a language like Java, they have absolutely no value at all - not zero, but literally no value - that is null

For instance: String s;

If you were to use s, it would actually have a value of null, because it holds absolute nothing.

An empty string, however, is a value - it is a string of no characters.

String s; //Inits to null
String a =""; //A blank string

Null is essentially 'nothing' - it's the default 'value' (to use the term loosely) that Java assigns to any Object variable that was not initialized.

Null isn't really a value - and as such, doesn't have properties. So, calling anything that is meant to return a value - such as .length(), will invariably return an error, because 'nothing' cannot have properties.

To go into more depth, by creating s1 = ""; you are initializing an object, which can have properties, and takes up relevant space in memory. By using s2; you are designating that variable name to be a String, but are not actually assigning any value at that point.

Solution for Radio Button in Swift 4.2 without using third-party libraries

Create RadioButtonController.swift file and place following code in it:

import UIKit

class RadioButtonController: NSObject {
    var buttonsArray: [UIButton]! {
        didSet {
            for b in buttonsArray {
                b.setImage(UIImage(named: "radio_off"), for: .normal)
                b.setImage(UIImage(named: "radio_on"), for: .selected)
            }
        }
    }
    var selectedButton: UIButton?
    var defaultButton: UIButton = UIButton() {
        didSet {
            buttonArrayUpdated(buttonSelected: self.defaultButton)
        }
    }

    func buttonArrayUpdated(buttonSelected: UIButton) {
        for b in buttonsArray {
            if b == buttonSelected {
                selectedButton = b
                b.isSelected = true
            } else {
                b.isSelected = false
            }
        }
    }
}

Use it as below in your view controller file:

import UIKit

class CheckoutVC: UIViewController {

    @IBOutlet weak var btnPaytm: UIButton!
    @IBOutlet weak var btnOnline: UIButton!
    @IBOutlet weak var btnCOD: UIButton!

    let radioController: RadioButtonController = RadioButtonController()

    override func viewDidLoad() {
        super.viewDidLoad()

        radioController.buttonsArray = [btnPaytm,btnCOD,btnOnline]
        radioController.defaultButton = btnPaytm
    }

    @IBAction func btnPaytmAction(_ sender: UIButton) {
        radioController.buttonArrayUpdated(buttonSelected: sender)
    }

    @IBAction func btnOnlineAction(_ sender: UIButton) {
        radioController.buttonArrayUpdated(buttonSelected: sender)
    }

    @IBAction func btnCodAction(_ sender: UIButton) {
        radioController.buttonArrayUpdated(buttonSelected: sender)
    }
}

Be sure to add radio_off and radio_on images in Assets.

As described in other answer, it's usually caused by incorrectly setting up permissions related to running Wireshark correctly.

I did some benchmarking where they do the same - sealed types.

var c1 = "";
var c2 = typeof(string);
object oc1 = c1;
object oc2 = c2;

var s1 = 0;
var s2 = '.';
object os1 = s1;
object os2 = s2;

bool b = false;

Stopwatch sw = Stopwatch.StartNew();
for (int i = 0; i < 10000000; i++)
{
    b = c1.GetType() == typeof(string); // ~60ms
    b = c1 is string; // ~60ms

    b = c2.GetType() == typeof(string); // ~60ms
    b = c2 is string; // ~50ms

    b = oc1.GetType() == typeof(string); // ~60ms
    b = oc1 is string; // ~68ms

    b = oc2.GetType() == typeof(string); // ~60ms
    b = oc2 is string; // ~64ms


    b = s1.GetType() == typeof(int); // ~130ms
    b = s1 is int; // ~50ms

    b = s2.GetType() == typeof(int); // ~140ms
    b = s2 is int; // ~50ms

    b = os1.GetType() == typeof(int); // ~60ms
    b = os1 is int; // ~74ms

    b = os2.GetType() == typeof(int); // ~60ms
    b = os2 is int; // ~68ms


    b = GetType1<string, string>(c1); // ~178ms
    b = GetType2<string, string>(c1); // ~94ms
    b = Is<string, string>(c1); // ~70ms

    b = GetType1<string, Type>(c2); // ~178ms
    b = GetType2<string, Type>(c2); // ~96ms
    b = Is<string, Type>(c2); // ~65ms

    b = GetType1<string, object>(oc1); // ~190ms
    b = Is<string, object>(oc1); // ~69ms

    b = GetType1<string, object>(oc2); // ~180ms
    b = Is<string, object>(oc2); // ~64ms


    b = GetType1<int, int>(s1); // ~230ms
    b = GetType2<int, int>(s1); // ~75ms
    b = Is<int, int>(s1); // ~136ms

    b = GetType1<int, char>(s2); // ~238ms
    b = GetType2<int, char>(s2); // ~69ms
    b = Is<int, char>(s2); // ~142ms

    b = GetType1<int, object>(os1); // ~178ms
    b = Is<int, object>(os1); // ~69ms

    b = GetType1<int, object>(os2); // ~178ms
    b = Is<int, object>(os2); // ~69ms
}

sw.Stop();
MessageBox.Show(sw.Elapsed.TotalMilliseconds.ToString());

The generic functions to test for generic types:

static bool GetType1<S, T>(T t)
{
    return t.GetType() == typeof(S);
}
static bool GetType2<S, T>(T t)
{
    return typeof(T) == typeof(S);
}
static bool Is<S, T>(T t)
{
    return t is S;
}

I tried for custom types as well and the results were consistent:

var c1 = new Class1();
var c2 = new Class2();
object oc1 = c1;
object oc2 = c2;

var s1 = new Struct1();
var s2 = new Struct2();
object os1 = s1;
object os2 = s2;

bool b = false;

Stopwatch sw = Stopwatch.StartNew();
for (int i = 0; i < 10000000; i++)
{
    b = c1.GetType() == typeof(Class1); // ~60ms
    b = c1 is Class1; // ~60ms

    b = c2.GetType() == typeof(Class1); // ~60ms
    b = c2 is Class1; // ~55ms

    b = oc1.GetType() == typeof(Class1); // ~60ms
    b = oc1 is Class1; // ~68ms

    b = oc2.GetType() == typeof(Class1); // ~60ms
    b = oc2 is Class1; // ~68ms


    b = s1.GetType() == typeof(Struct1); // ~150ms
    b = s1 is Struct1; // ~50ms

    b = s2.GetType() == typeof(Struct1); // ~150ms
    b = s2 is Struct1; // ~50ms

    b = os1.GetType() == typeof(Struct1); // ~60ms
    b = os1 is Struct1; // ~64ms

    b = os2.GetType() == typeof(Struct1); // ~60ms
    b = os2 is Struct1; // ~64ms


    b = GetType1<Class1, Class1>(c1); // ~178ms
    b = GetType2<Class1, Class1>(c1); // ~98ms
    b = Is<Class1, Class1>(c1); // ~78ms

    b = GetType1<Class1, Class2>(c2); // ~178ms
    b = GetType2<Class1, Class2>(c2); // ~96ms
    b = Is<Class1, Class2>(c2); // ~69ms

    b = GetType1<Class1, object>(oc1); // ~178ms
    b = Is<Class1, object>(oc1); // ~69ms

    b = GetType1<Class1, object>(oc2); // ~178ms
    b = Is<Class1, object>(oc2); // ~69ms


    b = GetType1<Struct1, Struct1>(s1); // ~272ms
    b = GetType2<Struct1, Struct1>(s1); // ~140ms
    b = Is<Struct1, Struct1>(s1); // ~163ms

    b = GetType1<Struct1, Struct2>(s2); // ~272ms
    b = GetType2<Struct1, Struct2>(s2); // ~140ms
    b = Is<Struct1, Struct2>(s2); // ~163ms

    b = GetType1<Struct1, object>(os1); // ~178ms
    b = Is<Struct1, object>(os1); // ~64ms

    b = GetType1<Struct1, object>(os2); // ~178ms
    b = Is<Struct1, object>(os2); // ~64ms
}

sw.Stop();
MessageBox.Show(sw.Elapsed.TotalMilliseconds.ToString());

And the types:

sealed class Class1 { }
sealed class Class2 { }
struct Struct1 { }
struct Struct2 { }

Inference:

1. Calling GetType on structs is slower. GetType is defined on object class which can't be overridden in sub types and thus structs need to be boxed to be called GetType.

2. On an object instance, GetType is faster, but very marginally.

3. On generic type, if T is class, then is is much faster. If T is struct, then is is much faster than GetType but typeof(T) is much faster than both. In cases of T being class, typeof(T) is not reliable since its different from actual underlying type t.GetType.

In short, if you have an object instance, use GetType. If you have a generic class type, use is. If you have a generic struct type, use typeof(T). If you are unsure if generic type is reference type or value type, use is. If you want to be consistent with one style always (for sealed types), use is..

There's a lot of great answers but they either use command line or some external program for profiling and/or sorting the results.

I really missed some way I could use in my IDE (eclipse-PyDev) without touching the command line or installing anything. So here it is.

Profiling without command line

def count():
    from math import sqrt
    for x in range(10**5):
        sqrt(x)

if __name__ == '__main__':
    import cProfile, pstats
    cProfile.run("count()", "{}.profile".format(__file__))
    s = pstats.Stats("{}.profile".format(__file__))
    s.strip_dirs()
    s.sort_stats("time").print_stats(10)

See docs or other answers for more info.

The exact solution is;

$("#dialogDiv").dialog({ other options...,
    open: function (type, data) {
        $(this).parent().appendTo("form");
    }
});

This worked in ubuntu 16.04 for python 2.7:

sudo pip install mysql-connector

For me i've tried all the solutions in this question didn't work , i finally made it by .

copy the pod .h .m files into my project and imported the .h into my project c header.

then i went back to storyboard the class was UICountingLabel i removed it and hit enter ( empty no class ) , then i added it again and hit enter, worked successfully .

IRB has a setting for this awful "feature", which you can customize.

Create a file called ~/.irbrc that includes the following line:

IRB.conf[:BACK_TRACE_LIMIT] = 100

This will allow you to see 100 stack frames in irb, at least. I haven't been able to find an equivalent setting for the non-interactive runtime.

Detailed information about IRB customization can be found in the Pickaxe book.

No you don't have to put credentials, You have to put headers on client side eg:

 $http({
        url: 'url of service',
        method: "POST",
        data: {test :  name },
        withCredentials: true,
        headers: {
                    'Content-Type': 'application/json; charset=utf-8'
        }
    });

And and on server side you have to put headers to this is example for nodejs:

/**
 * On all requests add headers
 */
app.all('*', function(req, res,next) {


    /**
     * Response settings
     * @type {Object}
     */
    var responseSettings = {
        "AccessControlAllowOrigin": req.headers.origin,
        "AccessControlAllowHeaders": "Content-Type,X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5,  Date, X-Api-Version, X-File-Name",
        "AccessControlAllowMethods": "POST, GET, PUT, DELETE, OPTIONS",
        "AccessControlAllowCredentials": true
    };

    /**
     * Headers
     */
    res.header("Access-Control-Allow-Credentials", responseSettings.AccessControlAllowCredentials);
    res.header("Access-Control-Allow-Origin",  responseSettings.AccessControlAllowOrigin);
    res.header("Access-Control-Allow-Headers", (req.headers['access-control-request-headers']) ? req.headers['access-control-request-headers'] : "x-requested-with");
    res.header("Access-Control-Allow-Methods", (req.headers['access-control-request-method']) ? req.headers['access-control-request-method'] : responseSettings.AccessControlAllowMethods);

    if ('OPTIONS' == req.method) {
        res.send(200);
    }
    else {
        next();
    }


});

git branch copyOfMyBranch MyBranch

This avoids the potentially time-consuming and unnecessary act of checking out a branch. Recall that a checkout modifies the "working tree", which could take a long time if it is large or contains large files (images or videos, for example).

Map<String, String> d = new HashMap<>();

void input(String u, String p, String e) {
    read();
    if (e.equals("login")) login(u, p);
    else if (e.equals("register")) register(u, p);
    write();
}

void read() {
    d = new HashMap<>();
    String s = "";
    try {
        s = new String(Files.readAllBytes(Paths.get("data.txt")));
    }catch(IOException e) {
        e.printStackTrace();
    }
    String [] pairs = s.split("\n");
    for (int i = 0; i < pairs.length; i++) {
        d.put(pairs[i].split(",")[0], pairs[i].split(",")[1]);
    }
}

void write() {
    try (FileWriter m = new FileWriter("data.txt")) {
        for (Map.Entry<String, String> entry : d.entrySet()) {
            m.write(entry.getKey() + "," + entry.getValue() + "\n");    
        }
        m.close();
    }catch (IOException e) {
        e.printStackTrace();
    }
}

boolean login(String u, String p) {
    return (d.get(u).equals(p)) ? true : false;
}

boolean register(String u, String p) {
    if (d.containsKey(u)) return false;
    d.put(u, p);
    return true;
}

Another option is to use one of my personal favorite CSS tools: box-shadow.

A box shadow is really a drop-shadow on the node. It looks like this:

-moz-box-shadow: 1px 2px 3px rgba(0,0,0,.5);
-webkit-box-shadow: 1px 2px 3px rgba(0,0,0,.5);
box-shadow: 1px 2px 3px rgba(0,0,0,.5);

The arguments are:

1px: Horizontal offset of the effect. Positive numbers shift it right, negative left.
2px: Vertical offset of the effect. Positive numbers shift it down, negative up.
3px: The blur effect.  0 means no blur.
color: The color of the shadow.

So, you could leave your current design, and add a box-shadow like:

box-shadow: 0px -2px 2px rgba(34,34,34,0.6);

This should give you a 'blurry' top-edge.

This website will help with more information: http://css-tricks.com/snippets/css/css-box-shadow/

You can't. This is an open issue in TypeScript: https://github.com/Microsoft/TypeScript/issues/19573

findIndex works for modern browsers:

var myArr = [{id:'a'},{id:'myid'},{id:'c'}];
var index = myArr.findIndex(function(o){
  return o.id === 'myid';
})
if (index !== -1) myArr.splice(index, 1);

Given a list:

var list = new List<Child>()
{
    new Child()
        {School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "John"},
    new Child()
        {School = "School2", FavoriteColor = "blue", Friend = "Bob", Name = "Pete"},
    new Child()
        {School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "Fred"},
    new Child()
        {School = "School2", FavoriteColor = "blue", Friend = "Fred", Name = "Bob"},
};

The query would look like:

var newList = list
    .GroupBy(x => new {x.School, x.Friend, x.FavoriteColor})
    .Select(y => new ConsolidatedChild()
        {
            FavoriteColor = y.Key.FavoriteColor,
            Friend = y.Key.Friend,
            School = y.Key.School,
            Children = y.ToList()
        }
    );

Test code:

foreach(var item in newList)
{
    Console.WriteLine("School: {0} FavouriteColor: {1} Friend: {2}", item.School,item.FavoriteColor,item.Friend);
    foreach(var child in item.Children)
    {
        Console.WriteLine("\t Name: {0}", child.Name);
    }
}

Result:

School: School1 FavouriteColor: blue Friend: Bob
    Name: John
    Name: Fred
School: School2 FavouriteColor: blue Friend: Bob
    Name: Pete
School: School2 FavouriteColor: blue Friend: Fred
    Name: Bob

If you just want to remove "username1" you can use a simple replace.

name.replace("username1,", "")

or you could use split like you mentioned.

var name = "username1, username2 and username3 like this post.".split(",")[1];      
$("h1").text(name);

There is also a very interesting article dedicated to this topic: Controlling startup order in Compose

In windows, run your terminal as admin (in case there are permission issues as I had). Then use a specific node version (say 7.8.0) by

nvm use 7.8.0

then update your npm to desired specific version by

npm install -g [email protected]

One reason you might want to host on an external server is to work around the browser limitations of concurent connections to particular server.

However, given that the jQuery file you are using will likely not change very often, the browser cache will kick in and make that point moot for the most part.

Second reason to host it on external server is to lower the traffic to your own server.

However, given the size of jQuery, chances are it will be a small part of your traffic. You should probably try to optimize your actual content.

Starting June 2019, with Windows 10, you won't have to change the codepage.

Through the use of the Consolas font, partial Unicode support will be provided.

As documented in Microsoft/Terminal issue 387:

There are 87,887 ideographs currently in Unicode. You need all of them too?
We need a boundary, and characters beyond that boundary should be handled by font fallback / font linking / whatever.

What Consolas should cover:

• Characters that used as symbols that used by modern OSS programs in CLI.
• These characters should follow Consolas' design and metrics, and properly aligned with existing Consolas characters.

What Consolas should NOT cover:

• Characters and punctuation of scripts that beyond Latin, Greek and Cyrillic, especially characters need complex shaping (like Arabic).
• These characters should be handled with font fallback.

Hashtables/Dictionaries are O(1) performance, meaning that performance is not a function of size. That's important to know.

EDIT: In practice, the average time complexity for Hashtable/Dictionary<> lookups is O(1).

You could also try a pre/post checkout hook might do the trick.

You can use String.Replace which basically removes all occurrences

line.Replace(@"\", ""); 

On second thought, this is probably just as fast as anything here.

def tail( f, window=20 ):
    lines= ['']*window
    count= 0
    for l in f:
        lines[count%window]= l
        count += 1
    print lines[count%window:], lines[:count%window]

It's a lot simpler. And it does seem to rip along at a good pace.

You need to have the System.Linq namespace included in your view since Select is an extension method. You have a couple of options on how to do this:

Add @using System.Linq to the top of your cshtml file.

If you find that you will be using this namespace often in many of your views, you can do this for all views by modifying the web.config inside of your Views folder (not the one at the root). You should see a pages/namespace XML element, create a new add child that adds System.Linq. Here is an example:

<configuration>
    <system.web.webPages.razor>
        <pages>
            <namespaces>
                <add namespace="System.Linq" />

There's no special case for String, because String is an ordinary referential type on JVM, in contrast with Java primitives (int, double, ...) -- storing them in a reference Array<T> requires boxing them into objects like Integer and Double. The purpose of specialized arrays like IntArray in Kotlin is to store non-boxed primitives, getting rid of boxing and unboxing overhead (the same as Java int[] instead of Integer[]).

You can use Array<String> (and Array<String?> for nullables), which is equivalent to String[] in Java:

val stringsOrNulls = arrayOfNulls<String>(10) // returns Array<String?>
val someStrings = Array<String>(5) { "it = $it" }
val otherStrings = arrayOf("a", "b", "c")

Change the .env file as follow

MAIL_DRIVER=smtp
MAIL_HOST=smtp.googlemail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=password
MAIL_ENCRYPTION=tls

And the go to the gmail security section ->Allow Less secure app access

Then run

php artisan config:clear

Refresh the site

You can edit this behavior in:

Tools->Options->Text Editor->All Languages->Tabs

Change Tab to use "Insert Spaces" instead of "Keep Tabs".

Note you can also specify this per language if you wish to have different behavior in a specific language.

This is my solution to move multiple children elements up and down inside the parent element. Works well for moving selected options in listbox (<select multiple></select>)

Move up:

$(parent).find("childrenSelector").each((idx, child) => {
    $(child).insertBefore($(child).prev().not("childrenSelector"));
});

Move down:

$($(parent).find("childrenSelector").get().reverse()).each((idx, child) => {
    $(opt).insertAfter($(child).next().not("childrenSelector"));
});

Now that I've separated the classes to .h and .cpp files do I need to use a makefile or can I still use the "g++ main.cpp" command?

Compiling several files at once is a poor choice if you are going to put that into the Makefile.

Normally in a Makefile (for GNU/Make), it should suffice to write that:

# "all" is the name of the default target, running "make" without params would use it
all: executable1

# for C++, replace CC (c compiler) with CXX (c++ compiler) which is used as default linker
CC=$(CXX)

# tell which files should be used, .cpp -> .o make would do automatically
executable1: file1.o file2.o

That way make would be properly recompiling only what needs to be recompiled. One can also add few tweaks to generate the header file dependencies - so that make would also properly rebuild what's need to be rebuilt due to the header file changes.

This feature has been added in dplyr v0.3. You can now pass a named character vector to the by argument in left_join (and other joining functions) to specify which columns to join on in each data frame. With the example given in the original question, the code would be:

left_join(test_data, kantrowitz, by = c("first_name" = "name"))

For those using the ControllerAs syntax, just declare the controller label in the $routeprovider as follows:

$routeprovider
        .when('/link', {
            templateUrl: 'templateUrl',
            controller: 'UploadsController as ctrl'
        })

or

$routeprovider
        .when('/link', {
            templateUrl: 'templateUrl',
            controller: 'UploadsController'
            controllerAs: 'ctrl'
        })

After declaring the $routeprovider, do not supply the controller as in the view. Instead use the label in the view.

Click \Build\Select Build Variant... in Android Studio. And choose release.

You can use myMap.forEach, and in each loop, using map.set to change value.

myMap = new Map([_x000D_
  ["a", 1],_x000D_
  ["b", 2],_x000D_
  ["c", 3]_x000D_
]);_x000D_
_x000D_
for (var [key, value] of myMap.entries()) {_x000D_
  console.log(key + ' = ' + value);_x000D_
}_x000D_
_x000D_
_x000D_
myMap.forEach((value, key, map) => {_x000D_
  map.set(key, value+1)_x000D_
})_x000D_
_x000D_
for (var [key, value] of myMap.entries()) {_x000D_
  console.log(key + ' = ' + value);_x000D_
}

There are several ways to do a cross join or cartesian product:

SELECT column_names FROM table1 CROSS JOIN table2;

SELECT column_names FROM table1, table2;

SELECT column_names FROM table1 JOIN table2;

Neglecting the on condition in the third case is what results in a cross join.

SqlCommand yourCommand = new SqlCommand();
yourCommand.Connection = yourSqlConn;
yourCommand.Parameters.Add("@yourParam");
yourCommand.Parameters["@yourParam"].Direction = ParameterDirection.Output;

// execute your query successfully

int yourResult = yourCommand.Parameters["@yourParam"].Value;

I crossed the same error, but it is not due to the file is locked, but the file is missing.

The reason why VS tried to copy an not existing file, is because of the Post-build event command.

After I cleared that, problem solved.

UPDATE:

As @rhughes commented:

The real issue is how to get the command here to work, rather than to remove it.

and he is absolutely right.

Dim proc As New Process()
Dim psi As New ProcessStartInfo()

psi.CreateNoWindow = True
psi.FileName = "cmd.exe"
psi.Arguments = "/C net stop YOURSERVICENAMEHERE && net start YOURSERVICENAMEHERE"
psi.LoadUserProfile = False
psi.UseShellExecute = False
psi.WindowStyle = ProcessWindowStyle.Hidden
proc.StartInfo = psi
proc.Start()

You could use np.where to find where you have NaN:

import numpy as np

a = np.array([[   0,   43,   67,    0,   38],
              [ 100,   86,   96,  100,   94],
              [  76,   79,   83,   89,   56],
              [  88,   np.nan,   67,   89,   81],
              [  94,   79,   67,   89,   69],
              [  88,   79,   58,   72,   63],
              [  76,   79,   71,   67,   56],
              [  71,   71,   np.nan,   56,  100]])

b = np.where(np.isnan(a), 0, a)

In [20]: b
Out[20]: 
array([[   0.,   43.,   67.,    0.,   38.],
       [ 100.,   86.,   96.,  100.,   94.],
       [  76.,   79.,   83.,   89.,   56.],
       [  88.,    0.,   67.,   89.,   81.],
       [  94.,   79.,   67.,   89.,   69.],
       [  88.,   79.,   58.,   72.,   63.],
       [  76.,   79.,   71.,   67.,   56.],
       [  71.,   71.,    0.,   56.,  100.]])

Use this:

SimpleDateFormat format = new SimpleDateFormat("HH:mm");

Date d1 = format.parse(strStartTime);
Date d2 = format.parse(strEndTime);

long diff = d2.getTime() - d1.getTime();
long diffSeconds,diffMinutes,diffHours;

if (diff > 0) {
diffSeconds = diff / 1000 % 60;
diffMinutes = diff / (60 * 1000) % 60;
diffHours = diff / (60 * 60 * 1000);
}
else{
long diffpos = (24*((60 * 60 * 1000))) + diff;
diffSeconds = diffpos / 1000 % 60;
diffMinutes = diffpos / (60 * 1000) % 60;
diffHours = (diffpos / (60 * 60 * 1000));
}

(Also it is important that for example if the startTime it's 23:00 and endTime 1:00 to get a duration of 2:00.)

the "else" part can get it correct

Use dbms_lob.instr and dbms_lob.substr, just like regular InStr and SubstStr functions.

And you should use neither if you have plenty of RAM. Redis and MongoDB come to the price of a general purpose tool. This introduce a lot of overhead.

There was the saying that Redis is 10 times faster than Mongo. That might not be that true anymore. MongoDB (if i remember correctly) claimed to beat memcache for storing and caching documents as long as the memory configurations are the same.

Anyhow. Redis good, MongoDB is good. If you care about substructures and need aggregation go for MongoDB. If storing keys and values is your main concern its all about Redis. (or any other key value store).

By default, Jenkins stores all of its data in this directory on the file system.

There are a few ways to change the Jenkins home directory:

• Edit the JENKINS_HOME variable in your Jenkins configuration file (e.g. /etc/sysconfig/jenkins on Red Hat Linux).
• Use your web container's admin tool to set the JENKINS_HOME environment variable.
• Set the environment variable JENKINS_HOME before launching your web container, or before launching Jenkins directly from the WAR file.
• Set the JENKINS_HOME Java system property when launching your web container, or when launching Jenkins directly from the WAR file.
• Modify web.xml in jenkins.war (or its expanded image in your web container). This is not recommended. This value cannot be changed while Jenkins is running. It is shown here to help you ensure that your configuration is taking effect.

Use 'event.currentTarget.performance.navigation.type' to determine the type of navigation. This is working in IE, FF and Chrome.

function CallbackFunction(event) {
    if(window.event) {
        if (window.event.clientX < 40 && window.event.clientY < 0) {
            alert("back button is clicked");
        }else{
            alert("refresh button is clicked");
        }
    }else{
        if (event.currentTarget.performance.navigation.type == 2) {
            alert("back button is clicked");
        }
        if (event.currentTarget.performance.navigation.type == 1) {
            alert("refresh button is clicked");
        }           
    }
}

As mentioned by nux and micheg79 a node is left behind in the DOM after the dialog closes.

This can also be cleaned up simply by adding:

$(this).dialog('destroy').remove();

to the close method of the dialog. Example adding this line to eidylon's answer:

function jqAlert(outputMsg, titleMsg, onCloseCallback) {
    if (!titleMsg)
        titleMsg = 'Alert';

    if (!outputMsg)
        outputMsg = 'No Message to Display.';

    $("<div></div>").html(outputMsg).dialog({
        title: titleMsg,
        resizable: false,
        modal: true,
        buttons: {
            "OK": function () {
                $(this).dialog("close");
            }
        },
        close: function() { onCloseCallback();
                           /* Cleanup node(s) from DOM */
                           $(this).dialog('destroy').remove();
                          }
    });
}

EDIT: I had problems getting callback function to run and found that I had to add parentheses () to onCloseCallback to actually trigger the callback. This helped me understand why: In JavaScript, does it make a difference if I call a function with parentheses?

Old question, lots of good answers, but there might still be interest in another alternative...

The numpngw module that I recently put up on github (https://github.com/WarrenWeckesser/numpngw) can write animated PNG files from numpy arrays. (Update: numpngw is now on pypi: https://pypi.python.org/pypi/numpngw.)

For example, this script:

import numpy as np
import numpngw


img0 = np.zeros((64, 64, 3), dtype=np.uint8)
img0[:32, :32, :] = 255
img1 = np.zeros((64, 64, 3), dtype=np.uint8)
img1[32:, :32, 0] = 255
img2 = np.zeros((64, 64, 3), dtype=np.uint8)
img2[32:, 32:, 1] = 255
img3 = np.zeros((64, 64, 3), dtype=np.uint8)
img3[:32, 32:, 2] = 255
seq = [img0, img1, img2, img3]
for img in seq:
    img[16:-16, 16:-16] = 127
    img[0, :] = 127
    img[-1, :] = 127
    img[:, 0] = 127
    img[:, -1] = 127

numpngw.write_apng('foo.png', seq, delay=250, use_palette=True)

creates:

You'll need a browser that supports animated PNG (either directly or with a plugin) to see the animation.

Just making code shorter you can use ES6 features. The same things can be written as

app.get("/recipes", (req, res) => {
    res.render("recipes.ejs", {
        recipes
    });
}); 

And the Templeate can be render as the same!

<%if (recipes.length > 0) { %>
// Do something with more than 1 recipe
<% } %>

The trick is to implement a stable sort. I've created a Widget class that can contain your test data:

public class Widget : IComparable
{
    int x;
    int y;
    public int X
    {
        get { return x; }
        set { x = value; }
    }

    public int Y
    {
        get { return y; }
        set { y = value; }
    }

    public Widget(int argx, int argy)
    {
        x = argx;
        y = argy;
    }

    public int CompareTo(object obj)
    {
        int result = 1;
        if (obj != null && obj is Widget)
        {
            Widget w = obj as Widget;
            result = this.X.CompareTo(w.X);
        }
        return result;
    }

    static public int Compare(Widget x, Widget y)
    {
        int result = 1;
        if (x != null && y != null)                
        {                
            result = x.CompareTo(y);
        }
        return result;
    }
}

I implemented IComparable, so it can be unstably sorted by List.Sort().

However, I also implemented the static method Compare, which can be passed as a delegate to a search method.

I borrowed this insertion sort method from C# 411:

 public static void InsertionSort<T>(IList<T> list, Comparison<T> comparison)
        {           
            int count = list.Count;
            for (int j = 1; j < count; j++)
            {
                T key = list[j];

                int i = j - 1;
                for (; i >= 0 && comparison(list[i], key) > 0; i--)
                {
                    list[i + 1] = list[i];
                }
                list[i + 1] = key;
            }
    }

You would put this in the sort helpers class that you mentioned in your question.

Now, to use it:

    static void Main(string[] args)
    {
        List<Widget> widgets = new List<Widget>();

        widgets.Add(new Widget(0, 1));
        widgets.Add(new Widget(1, 1));
        widgets.Add(new Widget(0, 2));
        widgets.Add(new Widget(1, 2));

        InsertionSort<Widget>(widgets, Widget.Compare);

        foreach (Widget w in widgets)
        {
            Console.WriteLine(w.X + ":" + w.Y);
        }
    }

And it outputs:

0:1
0:2
1:1
1:2
Press any key to continue . . .

This could probably be cleaned up with some anonymous delegates, but I'll leave that up to you.

EDIT: And NoBugz demonstrates the power of anonymous methods...so, consider mine more oldschool :P

Inspired by the ideas presented here, I have developed a readable and convenient way to handle errors in bash scripts in my bash boilerplate project.

By simply sourcing the library, you get the following out of the box (i.e. it will halt execution on any error, as if using set -e thanks to a trap on ERR and some bash-fu):

There are some extra features that help handle errors, such as try and catch, or the throw keyword, that allows you to break execution at a point to see the backtrace. Plus, if the terminal supports it, it spits out powerline emojis, colors parts of the output for great readability, and underlines the method that caused the exception in the context of the line of code.

The downside is - it's not portable - the code works in bash, probably >= 4 only (but I'd imagine it could be ported with some effort to bash 3).

The code is separated into multiple files for better handling, but I was inspired by the backtrace idea from the answer above by Luca Borrione.

To read more or take a look at the source, see GitHub:

https://github.com/niieani/bash-oo-framework#error-handling-with-exceptions-and-throw

give the LI float: left (or right)

They will all be in the same line until there will be no more room in the container (your case, a ul). (forgot): If you have a block element after the floating elements, he will also stick to them, unless you give him a clear:both, OR put an empty div before it with clear:both

If you are using the default cursor, a MySQLdb.cursors.Cursor, the entire result set will be stored on the client side (i.e. in a Python list) by the time the cursor.execute() is completed.

Therefore, even if you use

for row in cursor:

you will not be getting any reduction in memory footprint. The entire result set has already been stored in a list (See self._rows in MySQLdb/cursors.py).

However, if you use an SSCursor or SSDictCursor:

import MySQLdb
import MySQLdb.cursors as cursors

conn = MySQLdb.connect(..., cursorclass=cursors.SSCursor)

then the result set is stored in the server, mysqld. Now you can write

cursor = conn.cursor()
cursor.execute('SELECT * FROM HUGETABLE')
for row in cursor:
    print(row)

and the rows will be fetched one-by-one from the server, thus not requiring Python to build a huge list of tuples first, and thus saving on memory.

Otherwise, as others have already stated, cursor.fetchall() and list(cursor) are essentially the same.
