sort dictionary 'in_dict' by value in decreasing order

sorted_dict = {r: in_dict[r] for r in sorted(in_dict, key=in_dict.get, reverse=True)}

example above

sorted_d = {r: d[r] for r in sorted(d, key=d.get('key3'), reverse=True)}

The csv.writer writerow method takes an iterable as an argument. Your result set has to be a list (rows) of lists (columns).

csvwriter.writerow(row)

Write the row parameter to the writer’s file object, formatted according to the current dialect.

Do either:

import csv
RESULTS = [
    ['apple','cherry','orange','pineapple','strawberry']
]
with open('output.csv','wb') as result_file:
    wr = csv.writer(result_file, dialect='excel')
    wr.writerows(RESULTS)

or:

import csv
RESULT = ['apple','cherry','orange','pineapple','strawberry']
with open('output.csv','wb') as result_file:
    wr = csv.writer(result_file, dialect='excel')
    wr.writerow(RESULT)

The shortest solution I know:

using(var memoryStream = new MemoryStream())
{
  sourceStream.CopyTo(memoryStream);
  return memoryStream.ToArray();
}

I posted a fix for this here

You can use this function to modify JSON.stringify to encode arrays, just post it near the beginning of your script (check the link above for more detail):

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

Depends on where you want to use the email. If it's on the client side, without sending it to a PHP script, JQuery (or javascript) can do the trick.

I've created a fiddle to explain the same - http://jsfiddle.net/qHcpR/

It has an alert which goes off on load and when you click the textbox itself.

theller's solution for wget is really useful, however, i found it does not print out the progress throughout the downloading process. It's perfect if you add one line after the print statement in reporthook.

import sys, urllib

def reporthook(a, b, c):
    print "% 3.1f%% of %d bytes\r" % (min(100, float(a * b) / c * 100), c),
    sys.stdout.flush()
for url in sys.argv[1:]:
    i = url.rfind("/")
    file = url[i+1:]
    print url, "->", file
    urllib.urlretrieve(url, file, reporthook)
print

Change the order you're including your scripts (jQuery first):

<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script type="text/javascript" src="./javascript.js"></script>
<script
    src="http://maps.googleapis.com/maps/api/js?key=YOUR_APIKEY&sensor=false">
</script>

The comparison needs to be evaluated fully inside EL ${ ... }, not outside.

<c:if test="${values.type eq 'object'}">

As to the docs, those ${} things are not JSTL, but EL (Expression Language) which is a whole subject at its own. JSTL (as every other JSP taglib) is just utilizing it. You can find some more EL examples here.

<c:if test="#{bean.booleanValue}" />
<c:if test="#{bean.intValue gt 10}" />
<c:if test="#{bean.objectValue eq null}" />
<c:if test="#{bean.stringValue ne 'someValue'}" />
<c:if test="#{not empty bean.collectionValue}" />
<c:if test="#{not bean.booleanValue and bean.intValue ne 0}" />
<c:if test="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

See also:

• Our EL wiki page

By the way, unrelated to the concrete problem, if I guess your intent right, you could also just call Object#getClass() and then Class#getSimpleName() instead of adding a custom getter.

<c:forEach items="${list}" var="value">
    <c:if test="${value['class'].simpleName eq 'Object'}">
        <!-- code here -->
    </c:if>
</c:forEeach>

Just set preventDefault and return false

   $('#your-identifier').click(function(e) {
        e.preventDefault();
        return false;
    });

This will be disabled link but still, you will see a clickable icon(hand) icon. You can remove that too with below

$('#your-identifier').css('cursor', 'auto');

For completeness, write_csv() from the readr package is faster and never writes row names

# install.packages('readr', dependencies = TRUE)
library(readr)
write_csv(t, "t.csv")

If you need to write big data out, use fwrite() from the data.table package. It's much faster than both write.csv and write_csv

# install.packages('data.table')
library(data.table)
fwrite(t, "t.csv")

Below is a benchmark that Edouard published on his site

microbenchmark(write.csv(data, "baseR_file.csv", row.names = F),
               write_csv(data, "readr_file.csv"),

               times = 10, unit = "s")

Alternatively you could update brew by installing it again. (Think I did this as El Capitan changed something)

Note: this is a heavy handed approach that will remove all applications installed via brew!

Try to install brew a fresh and it will tell how to uninstall.

At original time of writing to uninstall:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

Edit: As of 2020 to uninstall:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

I ran into this issue with Python 3.6 and Python 3.7. The top answer (running pip install --upgrade pip enum34) did not solve the problem.

I don't know why, but the reason why this error happen is because enum.py was missing from .venv/myvenv/lib/python3.7/.

But the file was in /usr/lib/python3.7/.

Following this answer, I just created the symbolic link by myself :

ln -s /usr/lib/python3.7/enum.py .venv/myvenv/lib/python3.7/enum.py

This gets asked a lot. Basically, no there isn't, not for .NET 4.0. You have to do it manually at the start of each new thread (or ThreadPool function). You could perhaps store the culture name (or just the culture object) in a static field to save having to hit the DB, but that's about it.

Update for 2017

My original answer was written in 2009. While it still works, I'd like to update it for 2017. Browsers can still behave differently. I trust the jQuery team to do a great job at maintaining cross-browser consistency. However, it's not necessary to include the entire library. In the jQuery source, the relevant portion is found on line 37 of dimensions.js. Here it is extracted and modified to work standalone:

function getWidth() {_x000D_
  return Math.max(_x000D_
    document.body.scrollWidth,_x000D_
    document.documentElement.scrollWidth,_x000D_
    document.body.offsetWidth,_x000D_
    document.documentElement.offsetWidth,_x000D_
    document.documentElement.clientWidth_x000D_
  );_x000D_
}_x000D_
_x000D_
function getHeight() {_x000D_
  return Math.max(_x000D_
    document.body.scrollHeight,_x000D_
    document.documentElement.scrollHeight,_x000D_
    document.body.offsetHeight,_x000D_
    document.documentElement.offsetHeight,_x000D_
    document.documentElement.clientHeight_x000D_
  );_x000D_
}_x000D_
_x000D_
console.log('Width:  ' +  getWidth() );_x000D_
console.log('Height: ' + getHeight() );

Original Answer

Since all browsers behave differently, you'll need to test for values first, and then use the correct one. Here's a function that does this for you:

function getWidth() {
  if (self.innerWidth) {
    return self.innerWidth;
  }

  if (document.documentElement && document.documentElement.clientWidth) {
    return document.documentElement.clientWidth;
  }

  if (document.body) {
    return document.body.clientWidth;
  }
}

and similarly for height:

function getHeight() {
  if (self.innerHeight) {
    return self.innerHeight;
  }

  if (document.documentElement && document.documentElement.clientHeight) {
    return document.documentElement.clientHeight;
  }

  if (document.body) {
    return document.body.clientHeight;
  }
}

Call both of these in your scripts using getWidth() or getHeight(). If none of the browser's native properties are defined, it will return undefined.

This gives error:

int len;
scanf("%d",&len);
char str[len]="";

This also gives error:

int len=5;
char str[len]="";

But this works fine:

int len=5;
char str[len]; //so the problem lies with assignment not declaration

You need to put value in the following way:

str[0]='a';
str[1]='b'; //like that; and not like str="ab";

In postgresql all foreign keys must reference a unique key in the parent table, so in your bar table you must have a unique (name) index.

See also http://www.postgresql.org/docs/9.1/static/ddl-constraints.html#DDL-CONSTRAINTS-FK and specifically:

Finally, we should mention that a foreign key must reference columns that either are a primary key or form a unique constraint.

Emphasis mine.

Are you using Windows? Just set the environment variable http_proxy...

set http_proxy=http://your-proxy-address.com:port

... and bower will pick this up. Rather than dealing with a unique config file in your project folder - right? (side-note: when-the-F! will windows allow us to create a .file using explorer? c'mon windows!)

You are probably having a problem with the sort of CSV file that you have.

Open the CSV file with a text editor, check that all the separations are done with the comma, and not semicolon and try the script again. It should work fine.

Have a look at sys.path:

>>> import sys
>>> print(sys.path)

When starting all over is not an option...

I deleted the log file in the .svn directory (I also deleted the offending file in .svn/props-base), did a cleanup, and resumed my update.

Here is an Alternative that worked for me:

yourFrame.setIconImage(Toolkit.getDefaultToolkit().getImage(getClass().getResource(Filepath)));

It's very similar to the accepted Answer.

exec 'print "hello";' * 2

should work, but I'm kind of ashamed that I thought of it.

Update: Just thought of another one:

for _ in " "*10: print "hello"

You can also do it without modulus. Just reset your counter when it matches.

if($counter == 2) { // matches every 3 iterations
   echo 'image-file';
   $counter = 0; 
}

You can use DAYS.between from java.time.temporal.ChronoUnit

e.g.

import java.time.temporal.ChronoUnit;

public long getDaysCountBetweenDates(LocalDate dateBefore, LocalDate dateAfter) {
    return DAYS.between(dateBefore, dateAfter);
}

Okay so there might be various reasons behind Sql Server Management Studio's(SSMS) above behaviour:

1.It seems that if our SSMS hasn't been opened for quite some while, the OS puts it to sleep.The solution is to manually activate our SQL server as shown below:

• Go to Computer Management-->Services and Applications-->Services. As you see that the status of this service is currently blank which means that it has stopped.
• Double click the SQL Server option and a wizard box will popup as shown below.Set the startup type to "Automatic" and click on the start button which will start our SQL service.
• Now check the status of your SQL Server. It will display as "Running".
• Also you need to check that other associated services which are also required by our SQL Server to fully function are also up and running such as SQL Server Browser,SQL Server Agent,etc.

2.The second reason could be due to incorrect credentials entered.So enter in the correct credentials.

3.If you happen to forget your credentials then follow the below steps:

• First what you could do is sign in using "Windows Authentication" instead of "SQL Server Authentication".This will work only if you are logged in as administrator.
• Second case what if you forget your local server name? No issues simply use "." instead of your server name and it should work.

NOTE: This will only work for local server and not for remote server.To connect to a remote server you need to have an I.P. address of your remote server.

It's a simplifications but very easy... You need to add the the focusable flag to the checkbox, as written before. You need also to add the clickable flag, as shown here:

android:focusable="false"
android:clickable="false"

Than you control the checkbox state from within the ListView (ListFragment in my case) onListItemClick event.

This the sample onListItemClick method:

public void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
//Get related checkbox and change flag status..
CheckBox cb = (CheckBox)v.findViewById(R.id.rowDone);
cb.setChecked(!cb.isChecked());
Toast.makeText(getActivity(), "Click item", Toast.LENGTH_SHORT).show();
}

If you want a generic error you can setup all $.ajax() (which $.get() uses underneath) requests jQuery makes to display an error using $.ajaxSetup(), for example:

$.ajaxSetup({
  error: function(xhr, status, error) {
    alert("An AJAX error occured: " + status + "\nError: " + error);
  }
});

Just run this once before making any AJAX calls (no changes to your current code, just stick this before somewhere). This sets the error option to default to the handler/function above, if you made a full $.ajax() call and specified the error handler then what you had would override the above.

align-self-start, align-self-center... in flexbox

.centercol h1{
    background: #F2EFE9;
    border-left: 3px solid #C6C1B8;
    color: #006BB6;
    display: block;
    align-self: center;
    font-weight: normal;
    font-size: 18px;
    padding: 3px 3px 3px 6px;
}

You can use CTE to get the distinct values of the second table, and then join that with the first table. You also need to get the distinct values based on LastName column. You do this with a Row_Number() partitioned by the LastName, and sorted by the FirstName.

Here's the code

;WITH SecondTableWithDistinctLastName AS
(
        SELECT  *
        FROM    (
                    SELECT  *,
                            ROW_NUMBER() OVER (PARTITION BY LastName ORDER BY FirstName) AS [Rank]
                    FROM    AddTbl
                )   
        AS      tableWithRank
        WHERE   tableWithRank.[Rank] = 1
) 
SELECT          a.FirstName, a.LastName, S.District
FROM            SecondTableWithDistinctLastName AS S
INNER JOIN      AddTbl AS a
    ON          a.LastName = S.LastName
ORDER   BY      a.FirstName

CLR, BCL and C#/VB.Net, ADO.NET, WinForms and/or ASP.NET. Most of the places that require additional .Net technologies, like WPF or WCF will call it out explicitly.

I would recommend reviewing this page on How to Write Go Code

It documents both how to structure your project in a go build friendly way, and also how to write tests. Tests do not need to be a cmd using the main package. They can simply be TestX named functions as part of each package, and then go test will discover them.

The structure suggested in that link in your question is a bit outdated, now with the release of Go 1. You no longer would need to place a pkg directory under src. The only 3 spec-related directories are the 3 in the root of your GOPATH: bin, pkg, src . Underneath src, you can simply place your project mypack, and underneath that is all of your .go files including the mypack_test.go

go build will then build into the root level pkg and bin.

So your GOPATH might look like this:

~/projects/
    bin/
    pkg/
    src/
      mypack/
        foo.go
        bar.go
        mypack_test.go

export GOPATH=$HOME/projects

$ go build mypack
$ go test mypack

Update: as of >= Go 1.11, the Module system is now a standard part of the tooling and the GOPATH concept is close to becoming obsolete.

<EditText
    android:id="@+id/search"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="@string/search_hint"
    android:inputType="text"
    android:imeOptions="actionSend" />

You can then listen for presses on the action button by defining a TextView.OnEditorActionListener for the EditText element. In your listener, respond to the appropriate IME action ID defined in the EditorInfo class, such as IME_ACTION_SEND. For example:

EditText editText = (EditText) findViewById(R.id.search);
editText.setOnEditorActionListener(new OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        boolean handled = false;
        if (actionId == EditorInfo.IME_ACTION_SEND) {
            sendMessage();
            handled = true;
        }
        return handled;
    }
});

A method has already been devised, however this way you don't need a temp file.

for /f "delims=" %%i in ('command') do set output=%%i

However, I'm sure this has its own exceptions and limitations.

The short answer is NO, PDO prepares will not defend you from all possible SQL-Injection attacks. For certain obscure edge-cases.

I'm adapting this answer to talk about PDO...

The long answer isn't so easy. It's based off an attack demonstrated here.

The Attack

So, let's start off by showing the attack...

$pdo->query('SET NAMES gbk');
$var = "\xbf\x27 OR 1=1 /*";
$query = 'SELECT * FROM test WHERE name = ? LIMIT 1';
$stmt = $pdo->prepare($query);
$stmt->execute(array($var));

In certain circumstances, that will return more than 1 row. Let's dissect what's going on here:

1. Selecting a Character Set

   $pdo->query('SET NAMES gbk');
   

   For this attack to work, we need the encoding that the server's expecting on the connection both to encode ' as in ASCII i.e. 0x27 and to have some character whose final byte is an ASCII \ i.e. 0x5c. As it turns out, there are 5 such encodings supported in MySQL 5.6 by default: big5, cp932, gb2312, gbk and sjis. We'll select gbk here.

   Now, it's very important to note the use of SET NAMES here. This sets the character set ON THE SERVER. There is another way of doing it, but we'll get there soon enough.

2. The Payload

   The payload we're going to use for this injection starts with the byte sequence 0xbf27. In gbk, that's an invalid multibyte character; in latin1, it's the string ¿'. Note that in latin1 and gbk, 0x27 on its own is a literal ' character.

   We have chosen this payload because, if we called addslashes() on it, we'd insert an ASCII \ i.e. 0x5c, before the ' character. So we'd wind up with 0xbf5c27, which in gbk is a two character sequence: 0xbf5c followed by 0x27. Or in other words, a valid character followed by an unescaped '. But we're not using addslashes(). So on to the next step...

3. $stmt->execute()

   The important thing to realize here is that PDO by default does NOT do true prepared statements. It emulates them (for MySQL). Therefore, PDO internally builds the query string, calling mysql_real_escape_string() (the MySQL C API function) on each bound string value.

   The C API call to mysql_real_escape_string() differs from addslashes() in that it knows the connection character set. So it can perform the escaping properly for the character set that the server is expecting. However, up to this point, the client thinks that we're still using latin1 for the connection, because we never told it otherwise. We did tell the server we're using gbk, but the client still thinks it's latin1.

   Therefore the call to mysql_real_escape_string() inserts the backslash, and we have a free hanging ' character in our "escaped" content! In fact, if we were to look at $var in the gbk character set, we'd see:

   ?' OR 1=1 /*

   Which is exactly what the attack requires.

4. The Query

   This part is just a formality, but here's the rendered query:

   SELECT * FROM test WHERE name = '?' OR 1=1 /*' LIMIT 1
   

Congratulations, you just successfully attacked a program using PDO Prepared Statements...

The Simple Fix

Now, it's worth noting that you can prevent this by disabling emulated prepared statements:

$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

This will usually result in a true prepared statement (i.e. the data being sent over in a separate packet from the query). However, be aware that PDO will silently fallback to emulating statements that MySQL can't prepare natively: those that it can are listed in the manual, but beware to select the appropriate server version).

The Correct Fix

The problem here is that we didn't call the C API's mysql_set_charset() instead of SET NAMES. If we did, we'd be fine provided we are using a MySQL release since 2006.

If you're using an earlier MySQL release, then a bug in mysql_real_escape_string() meant that invalid multibyte characters such as those in our payload were treated as single bytes for escaping purposes even if the client had been correctly informed of the connection encoding and so this attack would still succeed. The bug was fixed in MySQL 4.1.20, 5.0.22 and 5.1.11.

But the worst part is that PDO didn't expose the C API for mysql_set_charset() until 5.3.6, so in prior versions it cannot prevent this attack for every possible command! It's now exposed as a DSN parameter, which should be used instead of SET NAMES...

The Saving Grace

As we said at the outset, for this attack to work the database connection must be encoded using a vulnerable character set. utf8mb4 is not vulnerable and yet can support every Unicode character: so you could elect to use that instead—but it has only been available since MySQL 5.5.3. An alternative is utf8, which is also not vulnerable and can support the whole of the Unicode Basic Multilingual Plane.

Alternatively, you can enable the NO_BACKSLASH_ESCAPES SQL mode, which (amongst other things) alters the operation of mysql_real_escape_string(). With this mode enabled, 0x27 will be replaced with 0x2727 rather than 0x5c27 and thus the escaping process cannot create valid characters in any of the vulnerable encodings where they did not exist previously (i.e. 0xbf27 is still 0xbf27 etc.)—so the server will still reject the string as invalid. However, see @eggyal's answer for a different vulnerability that can arise from using this SQL mode (albeit not with PDO).

Safe Examples

The following examples are safe:

mysql_query('SET NAMES utf8');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

Because the server's expecting utf8...

mysql_set_charset('gbk');
$var = mysql_real_escape_string("\xbf\x27 OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

Because we've properly set the character set so the client and the server match.

$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$pdo->query('SET NAMES gbk');
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Because we've turned off emulated prepared statements.

$pdo = new PDO('mysql:host=localhost;dbname=testdb;charset=gbk', $user, $password);
$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(array("\xbf\x27 OR 1=1 /*"));

Because we've set the character set properly.

$mysqli->query('SET NAMES gbk');
$stmt = $mysqli->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$param = "\xbf\x27 OR 1=1 /*";
$stmt->bind_param('s', $param);
$stmt->execute();

Because MySQLi does true prepared statements all the time.

Wrapping Up

If you:

• Use Modern Versions of MySQL (late 5.1, all 5.5, 5.6, etc) AND PDO's DSN charset parameter (in PHP = 5.3.6)

OR

• Don't use a vulnerable character set for connection encoding (you only use utf8 / latin1 / ascii / etc)

OR

• Enable NO_BACKSLASH_ESCAPES SQL mode

You're 100% safe.

Otherwise, you're vulnerable even though you're using PDO Prepared Statements...

Addendum

I've been slowly working on a patch to change the default to not emulate prepares for a future version of PHP. The problem that I'm running into is that a LOT of tests break when I do that. One problem is that emulated prepares will only throw syntax errors on execute, but true prepares will throw errors on prepare. So that can cause issues (and is part of the reason tests are borking).

There are 2 solutions to paginate efficiently on a DB2 table :

1 - the technique using the function row_number() and the clause OVER which has been presented on another post ("SELECT row_number() OVER ( ORDER BY ... )"). On some big tables, I noticed sometimes a degradation of performances.

2 - the technique using a scrollable cursor. The implementation depends of the language used. That technique seems more robust on big tables.

I presented the 2 techniques implemented in PHP during a seminar next year. The slide is available on this link : http://gregphplab.com/serendipity/uploads/slides/DB2_PHP_Best_practices.pdf

This is a simple PHP script to return male female and user id as json value will be any random value as you call the script json.php .

Hope this help thanks

It took me a while to develop something that took the accepted answer and turned it into a robust function.

I am not sure about others, but I work in an environment with machines on both PowerShell version 2 and 3, so I needed to handle both. The following function offers a graceful fallback:

Function Get-PSScriptRoot
{
    $ScriptRoot = ""

    Try
    {
        $ScriptRoot = Get-Variable -Name PSScriptRoot -ValueOnly -ErrorAction Stop
    }
    Catch
    {
        $ScriptRoot = Split-Path $script:MyInvocation.MyCommand.Path
    }

    Write-Output $ScriptRoot
}

It also means that the function refers to the Script scope rather than the parent's scope as outlined by Michael Sorens in one of his blog posts.

If you are using MySQL or MariaDB, the easiest and performant way dump CSV for single table is -

SELECT customer_id, firstname, surname INTO OUTFILE '/exportdata/customers.txt'
  FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
  LINES TERMINATED BY '\n'
  FROM customers;

Now you can use other techniques to repeat this command for multiple tables. See more details here:

You may want to disable browser caching for all pages rendered by controllers (i.e. HTML pages), but keep caching in place for resources such as scripts, style sheets, and images. If you're using MVC4+ bundling and minification, you'll want to keep the default cache durations for scripts and stylesheets (very long durations, since the cache gets invalidated based on a change to a unique URL, not based on time).

In MVC4+, to disable browser caching across all controllers, but retain it for anything not served by a controller, add this to FilterConfig.RegisterGlobalFilters:

filters.Add(new DisableCache());

Define DisableCache as follows:

class DisableCache : ActionFilterAttribute
{
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
    }
}

Change your second table code like below.

<table style="border: 1px solid red;width:300px;display:block;">
<thead>
    <tr>
        <td width=150>Name</td>
        <td width=150>phone</td>
    </tr>
</thead>
<tbody style='height:50px;overflow:auto;display:block;width:317px;'>
    <tr>
        <td width=150>AAAA</td>
        <td width=150>323232</td>
    </tr>
    <tr>
        <td>BBBBB</td>
        <td>323232</td>
    </tr>
    <tr>
        <td>CCCCC</td>
        <td>3435656</td>
    </tr>
</tbody>
</table>

JSFIDDLE DEMO

The problem mainly occurs after updating OS X to El Capitan (OS X 10.11) or macOS Sierra (macOS 10.12).

This is because of file permission issues with El Capitan’s or later macOS's new SIP process. Try changing the permissions for the /usr/local directory:

$ sudo chown -R $(whoami):admin /usr/local  

If it still doesn't work, use these steps inside a terminal session and everything will be fine:

cd /usr/local/Library/Homebrew  
git reset --hard  
git clean -df
brew update

This may be because homebrew is not updated.

firstDigit = number/((int)(pow(10,(int)log(number))));

This should get your first digit using math instead of strings.

In your example log(543) = 2.73 which casted to an int is 2. pow(10, 2) = 100 543/100 = 5.43 but since it's an int it gets truncated to 5

I took another try at it, using the DataContractJsonSerializer class. This solves it:

The code looks like this:

using System.Runtime.Serialization;

[DataContract]
public class DataObject
{
    [DataMember(Name = "user_id")]
    public int UserId { get; set; }

    [DataMember(Name = "detail_level")]
    public string DetailLevel { get; set; }
}

And the test is:

using System.Runtime.Serialization.Json;

[TestMethod]
public void DataObjectSimpleParseTest()
{
        DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(DataObject));

        MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(JsonData));
        DataObject dataObject = serializer.ReadObject(ms) as DataObject;

        Assert.IsNotNull(dataObject);
        Assert.AreEqual("low", dataObject.DetailLevel);
        Assert.AreEqual(1234, dataObject.UserId);
}

The only drawback is that I had to change DetailLevel from an enum to a string - if you keep the enum type in place, the DataContractJsonSerializer expects to read a numeric value and fails. See DataContractJsonSerializer and Enums for further details.

In my opinion this is quite poor, especially as JavaScriptSerializer handles it correctly. This is the exception that you get trying to parse a string into an enum:

System.Runtime.Serialization.SerializationException: There was an error deserializing the object of type DataObject. The value 'low' cannot be parsed as the type 'Int64'. --->
System.Xml.XmlException: The value 'low' cannot be parsed as the type 'Int64'. --->  
System.FormatException: Input string was not in a correct format

And marking up the enum like this does not change this behaviour:

[DataContract]
public enum DetailLevel
{
    [EnumMember(Value = "low")]
    Low,
   ...
 }

This also seems to work in Silverlight.

The basic idea of static import is that whenever you are using a static class,a static variable or an enum,you can import them and save yourself from some typing.

I will elaborate my point with example.

import java.lang.Math;

class WithoutStaticImports {

 public static void main(String [] args) {
  System.out.println("round " + Math.round(1032.897));
  System.out.println("min " + Math.min(60,102));
 }
}

Same code, with static imports:

import static java.lang.System.out;
import static java.lang.Math.*;

class WithStaticImports {
  public static void main(String [] args) {
    out.println("round " + round(1032.897));
    out.println("min " + min(60,102));
  }
}

Note: static import can make your code confusing to read.

In my experience the pythonw.exe is faster at least with using pygame.

Oh, I hate % design for this too....

You may convert dividend to unsigned in a way like:

unsigned int offset = (-INT_MIN) - (-INT_MIN)%divider

result = (offset + dividend) % divider

where offset is closest to (-INT_MIN) multiple of module, so adding and subtracting it will not change modulo. Note that it have unsigned type and result will be integer. Unfortunately it cannot correctly convert values INT_MIN...(-offset-1) as they cause arifmetic overflow. But this method have advandage of only single additional arithmetic per operation (and no conditionals) when working with constant divider, so it is usable in DSP-like applications.

There's special case, where divider is 2^N (integer power of two), for which modulo can be calculated using simple arithmetic and bitwise logic as

dividend&(divider-1)

for example

x mod 2 = x & 1
x mod 4 = x & 3
x mod 8 = x & 7
x mod 16 = x & 15

More common and less tricky way is to get modulo using this function (works only with positive divider):

int mod(int x, int y) {
    int r = x%y;
    return r<0?r+y:r;
}

This just correct result if it is negative.

Also you may trick:

(p%q + q)%q

It is very short but use two %-s which are commonly slow.

obj={};

$.each(obj, function (key, value) {
    console.log(key+ ' : ' + value); //push the object value
});

for (var i in obj) {
    nameList += "" + obj[i] + "";//display the object value
}

$("id/class").html($(nameList).length);//display the length of object.

Don't forget that if you are concerned about reading in a file that might have huge lines that could swamp your RAM during runtime, you can always read the file piece-meal. See "Why slurping a file is bad".

File.open('file_path', 'rb') do |io|
  while chunk = io.read(16 * 1024) do
    something_with_the chunk
    # like stream it across a network
    # or write it to another file:
    # other_io.write chunk
  end
end

The portable way to do this is:

sed -e 's/[ \t][ \t]*/\
/g'

That's an actual newline between the backslash and the slash-g. Many sed implementations don't know about \n, so you need a literal newline. The backslash before the newline prevents sed from getting upset about the newline. (in sed scripts the commands are normally terminated by newlines)

With GNU sed you can use \n in the substitution, and \s in the regex:

sed -e 's/\s\s*/\n/g'

GNU sed also supports "extended" regular expressions (that's egrep style, not perl-style) if you give it the -r flag, so then you can use +:

sed -r -e 's/\s+/\n/g'

If this is for Linux only, you can probably go with the GNU command, but if you want this to work on systems with a non-GNU sed (eg: BSD, Mac OS-X), you might want to go with the more portable option.

I've searched the minimal solution possible to do PHP + WebSockets during hours, until I found this article:

Super simple PHP WebSocket example

It doesn't require any third-party library.

Here is how to do it: create a index.html containing this:

<html>
<body>
    <div id="root"></div>
    <script>
        var host = 'ws://<<<IP_OF_YOUR_SERVER>>>:12345/websockets.php';
        var socket = new WebSocket(host);
        socket.onmessage = function(e) {
            document.getElementById('root').innerHTML = e.data;
        };
    </script>
</body>
</html>

and open it in the browser, just after you have launched php websockets.php in the command-line (yes, it will be an event loop, constantly running PHP script), with this websockets.php file.

This works:

$output = $array1 + $array2;

I had similar problem. I r?n npm cache clear, closed android SDK manager(which was open before) and re-ran npm install -g cordova and that was enough to solve the problem.

Almost the same as Audrius cooked up some months ago, but you might find it a bit more readable with the defaults in the function head - the way you are used to with python:

@app.route('/<user_id>')
@app.route('/<user_id>/<username>')
def show(user_id, username='Anonymous'):
    return user_id + ':' + username

I was in exactly the same situation recently, mate, and I can tell you what I did.

It seems that you actually haven't executed your query. Try following:

return jsonify(json_list = qryresult.all())

[Edit]: Problem with jsonify is, that usually the objects cannot be jsonified automatically. Even Python's datetime fails ;)

What I have done in the past, is adding an extra property (like serialize) to classes that need to be serialized.

def dump_datetime(value):
    """Deserialize datetime object into string form for JSON processing."""
    if value is None:
        return None
    return [value.strftime("%Y-%m-%d"), value.strftime("%H:%M:%S")]

class Foo(db.Model):
    # ... SQLAlchemy defs here..
    def __init__(self, ...):
       # self.foo = ...
       pass

    @property
    def serialize(self):
       """Return object data in easily serializable format"""
       return {
           'id'         : self.id,
           'modified_at': dump_datetime(self.modified_at),
           # This is an example how to deal with Many2Many relations
           'many2many'  : self.serialize_many2many
       }
    @property
    def serialize_many2many(self):
       """
       Return object's relations in easily serializable format.
       NB! Calls many2many's serialize property.
       """
       return [ item.serialize for item in self.many2many]

And now for views I can just do:

return jsonify(json_list=[i.serialize for i in qryresult.all()])

Hope this helps ;)

[Edit 2019]: In case you have more complex objects or circular references, use a library like marshmallow).

well the only thing that will work is

python -m pip install pip==

you can and should run it under IDE terminal (mine was pycharm)

Normally svn add * works. But if you get message like svn: warning: W150002: due to mix off versioned and non-versioned files in working copy. Use this command:

svn add <path to directory> --force

or

svn add * --force

var myString = "Hello, how are you?";
myString.slice(0,8);

What about using a foreach loop, maybe you could work with that?

  int i = 0;
  foreach (var o in values)
  {
    print(names[i], o);
    i++;
  }

something like that perhaps?

Since many browsers block popups by default and popups are really ugly, I recommend using lightbox or thickbox.

They are prettier and are not popups. They are extra HTML markups that are appended to your document's body with the appropriate CSS content.

http://jquery.com/demo/thickbox/

Try this : (http://jsfiddle.net/TpqVx/)

.left-div {
    float: left;
    width: 100px;
    /*height: 20px;*/
    margin-right: 8px;
    background-color: linen;
}
.right-div {

    margin-left: 108px;
    background-color: lime;
}??

<div class="left-div">
    &nbsp;
</div>
<div class="right-div">
    My requirements are <b>[A]</b> Content in the two divs should line up at the top, <b>[B]</b> Long text in right-div should not wrap underneath left-div, and <b>[C]</b> I do not want to specify a width of right-div. I don't want to set the width of right-div because this markup needs to work within different widths.
</div>
<div style='clear:both;'>&nbsp;</div>

Hints :

• Just use float:left in your left-most div only.
• No real reason to use height, but anyway...
• Good practice to use <div 'clear:both'>&nbsp;</div> after your last div.

This did the trick for me: I was able to find which macro called a particular query. Incidentally, the reason someone who does know how to code in VBA would want to write something like this is when they've inherited something macro-ish written by someone who doesn't know how to code in VBA.

Here is what I use:

var f = parseFloat(value);
return (Math.floor(f * t)) / t;

You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:

• full path from file input using jquery
• How to get the file path from HTML input form in Firefox 3

In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file" field, ostensibly for backward compatibility reasons.

• http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-March/018981.html
• The Mystery of c:\fakepath Unveiled

So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.

Generally it means:

127 - command not found

but it can also mean that the command is found,
but a library that is required by the command is NOT found.

You can use getChanges() on Eloquent model even after persisting.

The query either returned no rows or is erroneus, thus FALSE is returned. Change it to

if (!$dbc || mysqli_num_rows($dbc) == 0)

mysqli_num_rows:

Return Values

Returns TRUE on success or FALSE on failure. For SELECT, SHOW, DESCRIBE or EXPLAIN mysqli_query() will return a result object.

Also you can make your domain object Director final. It is not perfect solution but it prevent creating proxy-subclass of you domain class.

I've just started using Typescript and I've been trying to solve a similar problem like this; how to tell the Typescript that I'm passing a callback without an interface.

After browsing a few answers on Stack Overflow and GitHub issues, I finally found a solution that may help anyone with the same problem.

A function's type can be defined with (arg0: type0) => returnType and we can use this type definition in another function's parameter list.

function runCallback(callback: (sum: number) => void, a: number, b: number): void {
    callback(a + b);
}

// Another way of writing the function would be:
// let logSum: (sum: number) => void = function(sum: number): void {
//     console.log(sum);
// };
function logSum(sum: number): void {
    console.log(`The sum is ${sum}.`);
}

runCallback(logSum, 2, 2);

Both FetchType.LAZY and FetchType.EAGER are used to define the default fetch plan.

Unfortunately, you can only override the default fetch plan for LAZY fetching. EAGER fetching is less flexible and can lead to many performance issues.

My advice is to restrain the urge of making your associations EAGER because fetching is a query-time responsibility. So all your queries should use the fetch directive to only retrieve what's necessary for the current business case.

Before and BeforeClass in JUnit

The function @Before annotation will be executed before each of test function in the class having @Test annotation but the function with @BeforeClass will be execute only one time before all the test functions in the class.

Similarly function with @After annotation will be executed after each of test function in the class having @Test annotation but the function with @AfterClass will be execute only one time after all the test functions in the class.

SampleClass

public class SampleClass {
    public String initializeData(){
        return "Initialize";
    }

    public String processDate(){
        return "Process";
    }
 }

SampleTest

public class SampleTest {

    private SampleClass sampleClass;

    @BeforeClass
    public static void beforeClassFunction(){
        System.out.println("Before Class");
    }

    @Before
    public void beforeFunction(){
        sampleClass=new SampleClass();
        System.out.println("Before Function");
    }

    @After
    public void afterFunction(){
        System.out.println("After Function");
    }

    @AfterClass
    public static void afterClassFunction(){
        System.out.println("After Class");
    }

    @Test
    public void initializeTest(){
        Assert.assertEquals("Initailization check", "Initialize", sampleClass.initializeData() );
    }

    @Test
    public void processTest(){
        Assert.assertEquals("Process check", "Process", sampleClass.processDate() );
    }

}

Output

Use Pre-request script tab to write javascript to get and save the date into a variable:

const dateNow= new Date();
pm.environment.set('currentDate', dateNow.toISOString());

and then use it in the request body as follows:

"currentDate": "{{currentDate}}"

A .NET Core version for replacing a defined set of string chars to a specific char. It leverages the recently introduced Span type and string.Create method.

The idea is to prepare a replacement array, so no actual comparison operations would be required for the each string char. Thus, the replacement process reminds the way a state machine works. In order to avoid initialization of all items of the replacement array, let's store oldChar ^ newChar (XOR'ed) values there, what gives the following benefits:

• If a char is not changing: ch ^ ch = 0 - no need to initialize non-changing items
• The final char can be found by XOR'ing: ch ^ repl[ch]:
  • ch ^ 0 = ch - not changed chars case
  • ch ^ (ch ^ newChar) = newChar - replaced char

So the only requirement would be to ensure that the replacement array is zero-ed when initialized. We'll be using ArrayPool<char> to avoid allocations each time the ReplaceAll method is called. And, in order to ensure that the arrays are zero-ed without expensive call to Array.Clear method, we'll be maintaining a pool dedicated for the ReplaceAll method. We'll be clearing the replacement array (exact items only) before returning it to the pool.

public static class StringExtensions
{
    private static readonly ArrayPool<char> _replacementPool = ArrayPool<char>.Create();

    public static string ReplaceAll(this string str, char newChar, params char[] oldChars)
    {
        // If nothing to do, return the original string.
        if (string.IsNullOrEmpty(str) ||
            oldChars is null ||
            oldChars.Length == 0)
        {
            return str;
        }

        // If only one character needs to be replaced,
        // use the more efficient `string.Replace`.
        if (oldChars.Length == 1)
        {
            return str.Replace(oldChars[0], newChar);
        }

        // Get a replacement array from the pool.
        var replacements = _replacementPool.Rent(char.MaxValue + 1);

        try
        {
            // Intialize the replacement array in the way that
            // all elements represent `oldChar ^ newChar`.
            foreach (var oldCh in oldChars)
            {
                replacements[oldCh] = (char)(newChar ^ oldCh);
            }

            // Create a string with replaced characters.
            return string.Create(str.Length, (str, replacements), (dst, args) =>
            {
                var repl = args.replacements;

                foreach (var ch in args.str)
                {
                    dst[0] = (char)(repl[ch] ^ ch);
                    dst = dst.Slice(1);
                }
            });
        }
        finally
        {
            // Clear the replacement array.
            foreach (var oldCh in oldChars)
            {
                replacements[oldCh] = char.MinValue;
            }

            // Return the replacement array back to the pool.
            _replacementPool.Return(replacements);
        }
    }
}

For MySQL Workbench 6.1: in the home window click on the server instance(connection)/ or create a new one. In the thus opened 'connection' tab click on 'server' -> 'data import'. The rest of the steps remain as in Vishy's answer.

Answer isE given that the rest are plainly wrong, but ..

Long Answer - It isn't that simple; it depends ...

Simple fact is, the garbage collector may never decide to garbage collection every single object that is a viable candidate for collection, not unless memory pressure is extremely high. And then there is the fact that Java is just as susceptible to memory leaks as any other language, they are just harder to cause, and thus harder to find when you do cause them!

The following article has many good details on how memory management works and doesn't work and what gets take up by what. How generational Garbage Collectors work and Thanks for the Memory ( Understanding How the JVM uses Native Memory on Windows and Linux )

If you read the links, I think you will get the idea that memory management in Java isn't as simple as a multiple choice question.

You just need to escape the period:

a <- c("NM_020506.1","NM_020519.1","NM_001030297.2","NM_010281.2","NM_011419.3", "NM_053155.2")

gsub("\\..*","",a)
[1] "NM_020506"    "NM_020519"    "NM_001030297" "NM_010281"    "NM_011419"    "NM_053155" 

I had this issue with Jenkins. The cause: I had renamed a module module to Module. I found out that git had gotten confused somehow and kept both module and Module directories, with the contents spread between both folders. The build.gradle was kept in module but the module's name was Module so it was unable to find the default configuration.

I fixed it by backing up the contents of Module, manually deleting module folder from the repo and restoring + pushing the lost files.

You need to specify the path where your chromedriver is located.

1. Download chromedriver for your desired platform from here.

2. Place chromedriver on your system path, or where your code is.

3. If not using a system path, link your chromedriver.exe (For non-Windows users, it's just called chromedriver):

   browser = webdriver.Chrome(executable_path=r"C:\path\to\chromedriver.exe")
   

   (Set executable_path to the location where your chromedriver is located.)

   If you've placed chromedriver on your System Path, you can shortcut by just doing the following:

   browser = webdriver.Chrome()

4. If you're running on a Unix-based operating system, you may need to update the permissions of chromedriver after downloading it in order to make it executable:

   chmod +x chromedriver

5. That's all. If you're still experiencing issues, more info can be found on this other StackOverflow article: Can't use chrome driver for Selenium

The main reason is that classic C casts make no distinction between what we call static_cast<>(), reinterpret_cast<>(), const_cast<>(), and dynamic_cast<>(). These four things are completely different.

A static_cast<>() is usually safe. There is a valid conversion in the language, or an appropriate constructor that makes it possible. The only time it's a bit risky is when you cast down to an inherited class; you must make sure that the object is actually the descendant that you claim it is, by means external to the language (like a flag in the object). A dynamic_cast<>() is safe as long as the result is checked (pointer) or a possible exception is taken into account (reference).

A reinterpret_cast<>() (or a const_cast<>()) on the other hand is always dangerous. You tell the compiler: "trust me: I know this doesn't look like a foo (this looks as if it isn't mutable), but it is".

The first problem is that it's almost impossible to tell which one will occur in a C-style cast without looking at large and disperse pieces of code and knowing all the rules.

Let's assume these:

class CDerivedClass : public CMyBase {...};
class CMyOtherStuff {...} ;

CMyBase  *pSomething; // filled somewhere

Now, these two are compiled the same way:

CDerivedClass *pMyObject;
pMyObject = static_cast<CDerivedClass*>(pSomething); // Safe; as long as we checked

pMyObject = (CDerivedClass*)(pSomething); // Same as static_cast<>
                                     // Safe; as long as we checked
                                     // but harder to read

However, let's see this almost identical code:

CMyOtherStuff *pOther;
pOther = static_cast<CMyOtherStuff*>(pSomething); // Compiler error: Can't convert

pOther = (CMyOtherStuff*)(pSomething);            // No compiler error.
                                                  // Same as reinterpret_cast<>
                                                  // and it's wrong!!!

As you can see, there is no easy way to distinguish between the two situations without knowing a lot about all the classes involved.

The second problem is that the C-style casts are too hard to locate. In complex expressions it can be very hard to see C-style casts. It is virtually impossible to write an automated tool that needs to locate C-style casts (for example a search tool) without a full blown C++ compiler front-end. On the other hand, it's easy to search for "static_cast<" or "reinterpret_cast<".

pOther = reinterpret_cast<CMyOtherStuff*>(pSomething);
      // No compiler error.
      // but the presence of a reinterpret_cast<> is 
      // like a Siren with Red Flashing Lights in your code.
      // The mere typing of it should cause you to feel VERY uncomfortable.

That means that, not only are C-style casts more dangerous, but it's a lot harder to find them all to make sure that they are correct.

You repository is bare, i.e. it does not have a working tree attached to it. You can clone it locally to create a working tree for it, or you could use one of several other options to tell Git where the working tree is, e.g. the --work-tree option for single commands, or the GIT_WORK_TREE environment variable. There is also the core.worktree configuration option but it will not work in a bare repository (check the man page for what it does).

# git --work-tree=/path/to/work/tree checkout master
# GIT_WORK_TREE=/path/to/work/tree git status

Its very simple. Just give the below command for listing all keyspaces.

Cqlsh> Describe keyspaces;

When do you choose functional programming over object oriented?

When you anticipate a different kind of software evolution:

• Object-oriented languages are good when you have a fixed set of operations on things, and as your code evolves, you primarily add new things. This can be accomplished by adding new classes which implement existing methods, and the existing classes are left alone.

• Functional languages are good when you have a fixed set of things, and as your code evolves, you primarily add new operations on existing things. This can be accomplished by adding new functions which compute with existing data types, and the existing functions are left alone.

When evolution goes the wrong way, you have problems:

• Adding a new operation to an object-oriented program may require editing many class definitions to add a new method.

• Adding a new kind of thing to a functional program may require editing many function definitions to add a new case.

This problem has been well known for many years; in 1998, Phil Wadler dubbed it the "expression problem". Although some researchers think that the expression problem can be addressed with such language features as mixins, a widely accepted solution has yet to hit the mainstream.

What are the typical problem definitions where functional programming is a better choice?

Functional languages excel at manipulating symbolic data in tree form. A favorite example is compilers, where source and intermediate languages change seldom (mostly the same things), but compiler writers are always adding new translations and code improvements or optimizations (new operations on things). Compilation and translation more generally are "killer apps" for functional languages.

Below is a suggested approach to Question #1 which I use if I wish to use the ForEach-Object cmdlet. It does not directly answer the question because it does not EXIT the pipeline. However, it may achieve the desired effect in Q#1. The only drawback an amateur like myself can see is when processing large pipeline iterations.

    $zStop = $false
    (97..122) | Where-Object {$zStop -eq $false} | ForEach-Object {
    $zNumeric = $_
    $zAlpha = [char]$zNumeric
    Write-Host -ForegroundColor Yellow ("{0,4} = {1}" -f ($zNumeric, $zAlpha))
    if ($zAlpha -eq "m") {$zStop = $true}
    }
    Write-Host -ForegroundColor Green "My PSVersion = 5.1.18362.145"

I hope this is of use. Happy New Year to all.

Here are some vendors you might me looking for

::-webkit-input-placeholder {color: tomato}
::-moz-placeholder          {color: tomato;} /* Firefox 19+ */
:-moz-placeholder           {color: tomato;} /* Firefox 18- */
:-ms-input-placeholder      {color: tomato;}

You can also style different states, such as focus

:focus::-webkit-input-placeholder {color: transparent}
:focus::-moz-placeholder          {color: transparent}
:focus:-moz-placeholder           {color: transparent}
:focus:-ms-input-placeholder      {color: transparent}

You can also do certain transitions on it, like

::-VENDOR-input-placeholder       {text-indent: 0px;   transition: text-indent 0.3s ease;}
:focus::-VENDOR-input-placeholder  {text-indent: 500px; transition: text-indent 0.3s ease;}

In general, an alternative to case when ... is coalesce(nullif(x,bad_value),y) (that cannot be used in OP's case). For example,

select coalesce(nullif(y,''),x), coalesce(nullif(x,''),y), *
from (     (select 'abc' as x, '' as y)
 union all (select 'def' as x, 'ghi' as y)
 union all (select '' as x, 'jkl' as y)
 union all (select null as x, 'mno' as y)
 union all (select 'pqr' as x, null as y)
) q

gives:

 coalesce | coalesce |  x  |  y  
----------+----------+-----+-----
 abc      | abc      | abc | 
 ghi      | def      | def | ghi
 jkl      | jkl      |     | jkl
 mno      | mno      |     | mno
 pqr      | pqr      | pqr | 
(5 rows)

One other thing. You may need to specify the -L option as well - eg

-Wl,-rpath,/path/to/foo -L/path/to/foo -lbaz

or you may end up with an error like

ld: cannot find -lbaz

With iOS7 you can simply change tintColor of the textField

You can do

$('.myCheckbox').attr('checked',true) //Standards compliant

or

$("form #mycheckbox").attr('checked', true)

If you have custom code in the onclick event for the checkbox that you want to fire, use this one instead:

$("#mycheckbox").click();

You can uncheck by removing the attribute entirely:

$('.myCheckbox').removeAttr('checked')

You can check all checkboxes like this:

$(".myCheckbox").each(function(){
    $("#mycheckbox").click()
});

The newer android phones in the market like HTC one, Xperia Z etc have resolutions in the >480dpi range, putting them in the new xxhdpi class as well. The new assets might be useful for them too.

From your comment to gnibbler answer, i'd say you want a list of pairs of key-value sorted by value:

sorted(data.items(), key=lambda x:x[1])

The head command can get the first n lines. Variations are:

head -7 file
head -n 7 file
head -7l file

which will get the first 7 lines of the file called "file". The command to use depends on your version of head. Linux will work with the first one.

To append lines to the end of the same file, use:

echo 'first line to add' >>file
echo 'second line to add' >>file
echo 'third line to add' >>file

or:

echo 'first line to add
second line to add
third line to add' >>file

to do it in one hit.

So, tying these two ideas together, if you wanted to get the first 10 lines of the input.txt file to output.txt and append a line with five "=" characters, you could use something like:

( head -10 input.txt ; echo '=====' ) > output.txt

In this case, we do both operations in a sub-shell so as to consolidate the output streams into one, which is then used to create or overwrite the output file.

Add border-collapse:collapse to the table.

Example:

table.myTable{
  border-collapse:collapse;
}

table.myTable tr{
  border:1px solid red;
}

This worked for me.

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

Php Version: 5.6

Symfony version: 2.3

Guzzle: 5.0

I had an experience recently about sending json with Guzzle. I use Symfony 2.3 so my guzzle version can be a little older.

I will also show how to use debug mode and you can see the request before sending it,

When i made the request as shown below got the successfull response;

use GuzzleHttp\Client;

$headers = [
        'Authorization' => 'Bearer ' . $token,        
        'Accept'        => 'application/json',
        "Content-Type"  => "application/json"
    ];        

    $body = json_encode($requestBody);

    $client = new Client();    

    $client->setDefaultOption('headers', $headers);
    $client->setDefaultOption('verify', false);
    $client->setDefaultOption('debug', true);

    $response = $client->post($endPoint, array('body'=> $body));

    dump($response->getBody()->getContents());

I know it's a bit late to answer this question, and maybe you already found the solution, but I'm posting the solution I found (after I googled a lot) so it may help a little:

1. Put log4j.properties under WEB-INF\classes of the project as mentioned previously in this thread.
2. Put log4j-xx.jar under WEB-INF\lib
3. Test if log4j was loaded: add -Dlog4j.debug @ the end of your java options of tomcat

Hope this will help.

In the most shared hosts you can't set it.

On a VPS or dedicated server, you can set it, but everything has its price.

On shared hosts, in general you receive a Linux account, something such as /home/(your username)/, and the equivalent of /var/www/html turns to /home/(your username)/public_html/ (or something similar, such as /home/(your username)/www)

If you're accessing your account via FTP, you automatically has accessing the your */home/(your username)/ folder, just find the www or public_html and put your site in it.

If you're using absolute path in the code, bad news, you need to refactor it to use relative paths in the code, at least in a shared host.

In Python 3.4 pathlib was introduced:

>>> from pathlib import Path
>>> p = Path('/etc/usr/lib')
>>> p
PosixPath('/etc/usr/lib')
>>> p.parent
PosixPath('/etc/usr')

It also comes with many other helpful features e.g. for joining paths using slashes or easily walking the directory tree.

For more information refer to the docs or this blog post, which covers the differences between os.path and pathlib.

I am suggesting a much simpler utility I just wrote. It's currently called par, but will be renamed soon to either parl or pll, haven't decided yet.

https://github.com/k-bx/par

API is as simple as:

par "script1.sh" "script2.sh" "script3.sh"

Prefixing commands can be done via:

par "PARPREFIX=[script1] script1.sh" "script2.sh" "script3.sh"

A control or window object in Windows Forms is just a wrapper around a Win32 window identified by a handle (sometimes called HWND). Most things you do with the control will eventually result in a Win32 API call that uses this handle. The handle is owned by the thread that created it (typically the main thread), and shouldn't be manipulated by another thread. If for some reason you need to do something with the control from another thread, you can use Invoke to ask the main thread to do it on your behalf.

For instance, if you want to change the text of a label from a worker thread, you can do something like this:

theLabel.Invoke(new Action(() => theLabel.Text = "hello world from worker thread!"));

To my experience on most SQL Servers there is no backup of the transaction log. Full backups or differential backups are common practice, but transaction log backups are really seldom. So the transaction log file grows forever (until the disk is full). In this case the recovery model should be set to "simple". Don't forget to modify the system databases "model" and "tempdb", too.

A backup of the database "tempdb" makes no sense, so the recovery model of this db should always be "simple".

SSL first connects to the host, so the host name and port number are transferred as clear text. When the host responds and the challenge succeeds, the client will encrypt the HTTP request with the actual URL (i.e. anything after the third slash) and and send it to the server.

There are several ways to break this security.

It is possible to configure a proxy to act as a "man in the middle". Basically, the browser sends the request to connect to the real server to the proxy. If the proxy is configured this way, it will connect via SSL to the real server but the browser will still talk to the proxy. So if an attacker can gain access of the proxy, he can see all the data that flows through it in clear text.

Your requests will also be visible in the browser history. Users might be tempted to bookmark the site. Some users have bookmark sync tools installed, so the password could end up on deli.ci.us or some other place.

Lastly, someone might have hacked your computer and installed a keyboard logger or a screen scraper (and a lot of Trojan Horse type viruses do). Since the password is visible directly on the screen (as opposed to "*" in a password dialog), this is another security hole.

Conclusion: When it comes to security, always rely on the beaten path. There is just too much that you don't know, won't think of and which will break your neck.

Use animation-delay:

div {
    width: 100px;
    height: 100px;
    background: red;
    opacity: 0;

    animation: fadeIn 3s;
    animation-delay: 5s;
    animation-fill-mode: forwards;
}

@keyframes fadeIn {
    from { opacity: 0; }
    to { opacity: 1; }
}

Fiddle

The following will just print out the content of the file:

cat $Path/FileName.txt

while read line;
do
echo $line     
done

Please check the following file

%SystemRoot%\system32\drivers\etc\host

The line which bind the host name with ip is probably missing a line which bind them togather

127.0.0.1  localhost

If the given line is missing. Add the line in the file

Could you also check your MySQL database's user table and tell us the host column value for the user which you are using. You should have user privilege for both the host "127.0.0.1" and "localhost" and use % as it is a wild char for generic host name.

Why not write it in Haxe (http://haxe.org/) and convert it to whatever you want it to be?

You have to add the reference to System.configuration in your solution. Also, include using System.Configuration;. Once you do that, you'll have access to all the configuration settings.

Using React Native 0.41 (in March 2017), targeting iOS, I just found it as easy as:

<Image source={require('./myimage.png')} />

The image file must exist in the same folder as the .js file requiring it.

I didn't have to change anything in the XCode project. It just worked. Maybe things have changed a lot in 2 years!

Note that if the filename has anything other than lower-case letters, or the path is anything more than "./", then for me, it started failing. Not sure what the restrictions are, but start simple and work forward.

Hope this helps someone, as many other answers here seem overly complex and full of (naughty) off-site links.

UPDATE: BTW - The official documentation for this is here: https://facebook.github.io/react-native/docs/images.html

In this way, you can initialize the int array in koltin.

 val values: IntArray = intArrayOf(1, 2, 3, 4, 5,6,7)

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

The shortcut is: CTRL+shift+- ("shift+-" results in "_") After typing the shortcut, nano will let you to enter the line you wanna jump to, type in the line number, then press ENTR.

I wanted to comment out a lot of lines in some config file on a server that only had vi (no nano), so visual method was cumbersome as well Here's how i did that.

1. Open file vi file
2. Display line numbers :set number! or :set number
3. Then use the line numbers to replace start-of-line with "#", how?

:35,77s/^/#/

Note: the numbers are inclusive, lines from 35 to 77, both included will be modified.

To uncomment/undo that, simply use :35,77s/^#//

If you want to add a text word as a comment after every line of code, you can also use:

:35,77s/$/#test/ (for languages like Python)

:35,77s/;$/;\/\/test/ (for languages like Java)

Here is a very good discussion about using regular expressions to validate email addresses; "Comparing E-mail Address Validating Regular Expressions"

Here is the current top expression, that is JavaScript compatible, for reference purposes:

/^[-a-z0-9~!$%^&*_=+}{\'?]+(\.[-a-z0-9~!$%^&*_=+}{\'?]+)*@([a-z0-9_][-a-z0-9_]*(\.[-a-z0-9_]+)*\.(aero|arpa|biz|com|coop|edu|gov|info|int|mil|museum|name|net|org|pro|travel|mobi|[a-z][a-z])|([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}))(:[0-9]{1,5})?$/i

You can use this.props.children to render whatever children the component contains:

const Wrap = ({ children }) => <div>{children}</div>

export default () => <Wrap><h1>Hello word</h1></Wrap>

In case above-accepted answer did not work, try below solution. You can use it for port 8080 or for any other ports.

sudo lsof -i tcp:3000 

Replace 3000 with whichever port you want. Run below command to kill that process.

sudo kill -9 PID

PID is process ID you want to kill.

Below is the output of commands on mac Terminal.

Plugin that scrolls (with animation) only when required

I've written a jQuery plugin that does exactly what it says on the tin (and also exactly what you require). The good thing is that it will only scroll container when element is actually off. Otherwise no scrolling will be performed.

It works as easy as this:

$("table tr:last").scrollintoview();

It automatically finds closest scrollable ancestor that has excess content and is showing scrollbars. So if there's another ancestor with overflow:auto but is not scrollable will be skipped. This way you don't need to provide scrollable element because sometimes you don't even know which one is scrollable (I'm using this plugin in my Sharepoint site where content/master is developer independent so it's beyond my control - HTML may change when site is operational so can scrollable containers).

Change table's default charset:

ALTER TABLE etape_prospection
  CHARACTER SET utf8,
  COLLATE utf8_general_ci;

To change string column charset exceute this query:

ALTER TABLE etape_prospection
  CHANGE COLUMN etape_prosp_comment etape_prosp_comment TEXT CHARACTER SET utf8 COLLATE utf8_general_ci;

Example:

<songs>
<song dateplayed="2011-07-24 19:40:26">
    <title>I left my heart on Europa</title>
    <artist>Ship of Nomads</artist>
</song>
<song dateplayed="2011-07-24 19:27:42">
    <title>Oh Ganymede</title>
    <artist>Beefachanga</artist>
</song>
<song dateplayed="2011-07-24 19:23:50">
    <title>Kallichore</title>
    <artist>Jewitt K. Sheppard</artist>
</song>

then:

<?php
$mysongs = simplexml_load_file('songs.xml');
echo $mysongs->song[0]->artist;
?>

Output on your browser: Ship of Nomads

An even better solution consists of using button tags to submit the form:

<form>
    ...
    <button type="submit" name="action" value="update">Update</button>
    <button type="submit" name="action" value="delete">Delete</button>
</form>

The HTML inside the button (e.g. ..>Update<.. is what is seen by the user; because there is HTML provided, the value is not user-visible; it is only sent to server. This way there is no inconvenience with internationalization and multiple display languages (in the former solution, the label of the button is also the value sent to the server).

 <android.support.design.widget.NavigationView
        android:id="@+id/navigation_view"
        android:background="#000"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:layout_gravity="start"
        app:headerLayout="@layout/header"
        app:itemTextColor="your color"
        app:menu="@menu/drawer" />

Using VS Professional 2019, I was trying to run a downloaded solution from a Udemy class on selenium automation testing, and most of the projects had errors in the project references sections. I tried cleaning, rebuilding, closing VS. Then, in VS, when I right clicked on the solution in Solution Explorer and chose Manage Nuget Packages for Solution, there were 2 available updates: for MSTest.TestAdapter and MSTest.TestFramework, and when I installed those, the error messages on the references for all the projects went away, for the references to those, as well as for the references to System and System.Core.

Replace whatever is in the address bar with this:

javascript:document.getElementById('serverTime').innerHTML='[text here]';

Example.

I think this is the most widely supported version (requiring only POSIX defined tr and od behavior):

cat "$file" | od -v -t x1 -A n | tr -d ' \n'

This uses od to print each byte as hex without address without skipping repeated bytes and tr to delete all spaces and linefeeds in the output. Note that not even the trailing linefeed is emitted here. (The cat is intentional to allow multicore processing where cat can wait for filesystem while od is still processing previously read part. Single core users may want replace that with < "$file" od ... to save starting one additional process.)

There are two approaches that I know of. The first is to tell the browser not to cache the page. Setting the Response to no cache takes care of that, however as you suspect the browser will often ignore this directive. The other approach is to set the date time of your response to a point in the future. I believe all browsers will correct this to the current time when they add the page to the cache, but it will show the page as newer when the comparison is made. I believe there may be some cases where a comparison is not made. I am not sure of the details and they change with each new browser release. Final note I have had better luck with pages that "refresh" themselves (another response directive). The refresh seems less likely to come from the cache.

Hope that helps.

There are specific libraries (like this one here) but maybe something very simple would do:

import time
import sys

toolbar_width = 40

# setup toolbar
sys.stdout.write("[%s]" % (" " * toolbar_width))
sys.stdout.flush()
sys.stdout.write("\b" * (toolbar_width+1)) # return to start of line, after '['

for i in xrange(toolbar_width):
    time.sleep(0.1) # do real work here
    # update the bar
    sys.stdout.write("-")
    sys.stdout.flush()

sys.stdout.write("]\n") # this ends the progress bar

Note: progressbar2 is a fork of progressbar which hasn't been maintained in years.

One possible workaround is inject the child controller in the parent controller using a init function.

Possible implementation:

<div ng-controller="ParentController as parentCtrl">
   ...

    <div ng-controller="ChildController as childCtrl" 
         ng-init="ChildCtrl.init()">
       ...
    </div>
</div>

Where in ChildController you have :

app.controller('ChildController',
    ['$scope', '$rootScope', function ($scope, $rootScope) {
    this.init = function() {
         $scope.parentCtrl.childCtrl = $scope.childCtrl;
         $scope.childCtrl.test = 'aaaa';
    };

}])

So now in the ParentController you can use :

app.controller('ParentController',
    ['$scope', '$rootScope', 'service', function ($scope, $rootScope, service) {

    this.save = function() {
        service.save({
            a:  $scope.parentCtrl.ChildCtrl.test
        });
     };

}])

Important:
To work properly you have to use the directive ng-controller and rename each controller using as like i did in the html eg.

Tips:
Use the chrome plugin ng-inspector during the process. It's going to help you to understand the tree.

While it's true that id(object) gets the object's address in the default CPython implementation, this is generally useless... you can't do anything with the address from pure Python code.

The only time you would actually be able to use the address is from a C extension library... in which case it is trivial to get the object's address since Python objects are always passed around as C pointers.

You can use fit-content value for width.

#wrap {
  width: -moz-fit-content;
  width: -webkit-fit-content;
  width: fit-content;
  margin: auto;   
}

Note: It works only in latest browsers.

@vignesh the single quotes are only needed if you are using js variables

<iframe src = "https://maps.google.com/maps?q=10.305385,77.923029&hl=es;z=14&amp;output=embed"></iframe>

You can just use the Select() extension method:

IEnumerable<int> integers = new List<int>() { 1, 2, 3, 4, 5 };
IEnumerable<string> strings = integers.Select(i => i.ToString());

Or in LINQ syntax:

IEnumerable<int> integers = new List<int>() { 1, 2, 3, 4, 5 };

var strings = from i in integers
              select i.ToString();

Edit the document or wiki page, and use the - [ ] and - [x] syntax to update your task list. Furthermore you can refer to this link.

Omitting the html, head, and body tags is certainly allowed by the HTML specs. The underlying reason is that browsers have always sought to be consistent with existing web pages, and the very early versions of HTML didn't define those elements. When HTML 2.0 first did, it was done in a way that the tags would be inferred when missing.

I often find it convenient to omit the tags when prototyping and especially when writing test cases as it helps keep the mark-up focused on the test in question. The inference process should create the elements in exactly the manner that you see in Firebug, and browsers are pretty consistent in doing that.

But...

IE has at least one known bug in this area. Even IE9 exhibits this. Suppose the markup is this:

<!DOCTYPE html>
<title>Test case</title>
<form action='#'>
   <input name="var1">
</form>

You should (and do in other browsers) get a DOM that looks like this:

HTML
    HEAD
        TITLE
    BODY
        FORM action="#"
            INPUT name="var1"

But in IE you get this:

HTML
    HEAD
       TITLE
       FORM action="#"
           BODY
               INPUT name="var1"
    BODY

See it for yourself.

This bug seems limited to the form start tag preceding any text content and any body start tag.

According to this posting by the lead Jenkins developer, Kohsuke Kawaguchi, in 2009, there is no group support for the built-in Jenkins user database. Group support is only usable when integrating Jenkins with LDAP or Active Directory. This appears to be the same in 2012.

However, as Vadim wrote in his answer, you don't need group support for the built-in Jenkins user database, thanks to the Role strategy plug-in.

The difference is that raw_input() does not exist in Python 3.x, while input() does. Actually, the old raw_input() has been renamed to input(), and the old input() is gone, but can easily be simulated by using eval(input()). (Remember that eval() is evil. Try to use safer ways of parsing your input if possible.)

Keep the breaks - you're less likely to run into trouble if/when you edit the code later if the breaks are already in place.

Having said that, it's considered by many (including me) to be bad practice to return from the middle of a function. Ideally a function should have one entry point and one exit point.

Obviously, there are a lot of solutions to this. Here is another one though:

wc -l somefile | tr -d "[:alpha:][:blank:][:punct:]"

This only outputs the number of lines, but the trailing newline character (\n) is present, if you don't want that either, replace [:blank:] with [:space:].

You can convert class component to hooks,but Material v4 has a withStyles HOC. https://material-ui.com/styles/basics/#higher-order-component-api Using this HOC you can keep your code unchanged.

If you are using an <a> element, just use this:

<a href="javascript:myJSFunc();" />myLink</a>

Personally I'd attach an event handler with JavaScript later on instead (using attachEvent or addEventListener or maybe <put your favorite JavaScript framework here > also).

TypeError: Cannot read property 'then' of undefined when calling a Django service using AngularJS.

If you are calling a Python service, the code will look like below:

this.updateTalentSupplier=function(supplierObj){
  var promise = $http({
    method: 'POST',
      url: bbConfig.BWS+'updateTalentSupplier/',
      data:supplierObj,
      withCredentials: false,
      contentType:'application/json',
      dataType:'json'
    });
    return promise; //Promise is returned 
}

We are using MongoDB as the database(I know it doesn't matter. But if someone is searching with MongoDB + Python (Django) + AngularJS the result should come.

if ($done)
{
    header("Location: /url/to/the/other/page");
    exit;
}

You can try a blank phrase:

document.add(new Phrase("\n"));

here's another method to center everything within anything.

Working Fiddle

HTML: (simple as ever)

<div class="Container">
    <div class="Content"> /*this can be an img, span, or everything else*/
        I'm the Content
    </div>
</div>

CSS:

.Container
{
    text-align: center;
}

    .Container:before
    {
        content: '';
        height: 100%;
        display: inline-block;
        vertical-align: middle;
    }

.Content
{
    display: inline-block;
    vertical-align: middle;
}

Benefits

The Container and Content height are unknown.

Centering without specific negative margin, without setting the line-height (so it works well with multiple line of text) and without a script, also Works great with CSS transitions.

alias jsonp='pbpaste | python -m json.tool'

This will pretty print JSON that's on the clipboard in OSX. Just Copy it then call the alias from a Bash prompt.

Whenever compiler found special character .. it gives these king of compile error .... what error i found is as following

error: stray '\302' in program and error: stray '\240' in program

....

Some piece of code i copied from chatting messanger. In messanger it was special character only.. after copiying into vim editor it changed to correct character only. But compiler was giving above error .. then .. that stamenet i wrote mannualy after .. it got resolve.. :)

You can use InitialCatalog Property or builder["Database"] works as well. I tested it with different case and it still works.

Another way to remove all transitions is with the unset keyword:

a.tags {
    transition: unset;
}

In the case of transition, unset is equivalent to initial, since transition is not an inherited property:

a.tags {
    transition: initial;
}

A reader who knows about unset and initial can tell that these solutions are correct immediately, without having to think about the specific syntax of transition.

You can delete any component by removing all its lines from app.module.ts . Its working fine for me.

I haven't used Angular, but reading the link above, it seems that you're trying to code for something that you don't need to handle. You make changes to state in your React component hierarchy (via this.setState()) and React will cause your component to be re-rendered (effectively 'listening' for changes). If you want to 'listen' from another component in your hierarchy then you have two options:

1. Pass handlers down (via props) from a common parent and have them update the parent's state, causing the hierarchy below the parent to be re-rendered.
2. Alternatively, to avoid an explosion of handlers cascading down the hierarchy, you should look at the flux pattern, which moves your state into data stores and allows components to watch them for changes. The Fluxxor plugin is very useful for managing this.

both of them works <%= f.submit class: "btn btn-primary" %> and <%= f.submit "Name of Button", class: "btn btn-primary "%>

You need to specify an access modifier for your variable. In this case you want it public.

public class Variables
{
    public static string name = "";
}

After this you can use the variable like this.

Variables.name

MSBuild (Visual Studio project/solution *.vcproj/*.sln):

Add to Additional options in Project Settings: /std:c++latest to enable latest features - currently C++17 as of VS2017, VS2015 Update 3.

https://blogs.msdn.microsoft.com/vcblog/2016/06/07/standards-version-switches-in-the-compiler/

/permissive- will disable non-standard C++ extensions and will enable standard conformance in VS2017.

https://blogs.msdn.microsoft.com/vcblog/2016/11/16/permissive-switch/

EDIT (Oct 2018): The latest VS2017 features are documented here:

https://docs.microsoft.com/en-gb/cpp/build/reference/std-specify-language-standard-version

VS2017 supports: /std:[c++14|c++17|c++latest] now. These flags can be set via the project's property pages:

To set this compiler option in the Visual Studio development environment

1. Open the project's Property Pages dialog box. For details, see Working with Project Properties.
2. Select Configuration Properties, C/C++, Language.
3. In C++ Language Standard, choose the language standard to support from the dropdown control, then choose OK or Apply to save your changes.

CMake:

Visual Studio 2017 (15.7+) supports CMake projects. CMake makes it possible to enable modern C++ features in various ways. The most basic option is to enable a modern C++ standard by setting a target's property in CMakeLists.txt:

add_library (${PROJECT_NAME})
set_property (TARGET ${PROJECT_NAME}
  PROPERTY
    # Enable C++17 standard compliance
    CXX_STANDARD 17
)

In the case of an interface library:

add_library (${PROJECT_NAME} INTERFACE)
target_compile_features (${PROJECT_NAME}
  INTERFACE
    # Enable C++17 standard compliance
    cxx_std_17
)

I think there could be a more consolidated effort in an answer to better explain the relationship between Python's datetime module, numpy's datetime64/timedelta64 and pandas' Timestamp/Timedelta objects.

The datetime standard library of Python

The datetime standard library has four main objects

• time - only time, measured in hours, minutes, seconds and microseconds
• date - only year, month and day
• datetime - All components of time and date
• timedelta - An amount of time with maximum unit of days

Create these four objects

>>> import datetime
>>> datetime.time(hour=4, minute=3, second=10, microsecond=7199)
datetime.time(4, 3, 10, 7199)

>>> datetime.date(year=2017, month=10, day=24)
datetime.date(2017, 10, 24)

>>> datetime.datetime(year=2017, month=10, day=24, hour=4, minute=3, second=10, microsecond=7199)
datetime.datetime(2017, 10, 24, 4, 3, 10, 7199)

>>> datetime.timedelta(days=3, minutes = 55)
datetime.timedelta(3, 3300)

>>> # add timedelta to datetime
>>> datetime.timedelta(days=3, minutes = 55) + \
    datetime.datetime(year=2017, month=10, day=24, hour=4, minute=3, second=10, microsecond=7199)
datetime.datetime(2017, 10, 27, 4, 58, 10, 7199)

NumPy's datetime64 and timedelta64 objects

NumPy has no separate date and time objects, just a single datetime64 object to represent a single moment in time. The datetime module's datetime object has microsecond precision (one-millionth of a second). NumPy's datetime64 object allows you to set its precision from hours all the way to attoseconds (10 ^ -18). It's constructor is more flexible and can take a variety of inputs.

Construct NumPy's datetime64 and timedelta64 objects

Pass an integer with a string for the units. See all units here. It gets converted to that many units after the UNIX epoch: Jan 1, 1970

>>> np.datetime64(5, 'ns') 
numpy.datetime64('1970-01-01T00:00:00.000000005')

>>> np.datetime64(1508887504, 's')
numpy.datetime64('2017-10-24T23:25:04')

You can also use strings as long as they are in ISO 8601 format.

>>> np.datetime64('2017-10-24')
numpy.datetime64('2017-10-24')

Timedeltas have a single unit

>>> np.timedelta64(5, 'D') # 5 days
>>> np.timedelta64(10, 'h') 10 hours

Can also create them by subtracting two datetime64 objects

>>> np.datetime64('2017-10-24T05:30:45.67') - np.datetime64('2017-10-22T12:35:40.123')
numpy.timedelta64(147305547,'ms')

Pandas Timestamp and Timedelta build much more functionality on top of NumPy

A pandas Timestamp is a moment in time very similar to a datetime but with much more functionality. You can construct them with either pd.Timestamp or pd.to_datetime.

>>> pd.Timestamp(1239.1238934) #defautls to nanoseconds
Timestamp('1970-01-01 00:00:00.000001239')

>>> pd.Timestamp(1239.1238934, unit='D') # change units
Timestamp('1973-05-24 02:58:24.355200')

>>> pd.Timestamp('2017-10-24 05') # partial strings work
Timestamp('2017-10-24 05:00:00')

pd.to_datetime works very similarly (with a few more options) and can convert a list of strings into Timestamps.

>>> pd.to_datetime('2017-10-24 05')
Timestamp('2017-10-24 05:00:00')

>>> pd.to_datetime(['2017-1-1', '2017-1-2'])
DatetimeIndex(['2017-01-01', '2017-01-02'], dtype='datetime64[ns]', freq=None)

Converting Python datetime to datetime64 and Timestamp

>>> dt = datetime.datetime(year=2017, month=10, day=24, hour=4, 
                   minute=3, second=10, microsecond=7199)
>>> np.datetime64(dt)
numpy.datetime64('2017-10-24T04:03:10.007199')

>>> pd.Timestamp(dt) # or pd.to_datetime(dt)
Timestamp('2017-10-24 04:03:10.007199')

Converting numpy datetime64 to datetime and Timestamp

>>> dt64 = np.datetime64('2017-10-24 05:34:20.123456')
>>> unix_epoch = np.datetime64(0, 's')
>>> one_second = np.timedelta64(1, 's')
>>> seconds_since_epoch = (dt64 - unix_epoch) / one_second
>>> seconds_since_epoch
1508823260.123456

>>> datetime.datetime.utcfromtimestamp(seconds_since_epoch)
>>> datetime.datetime(2017, 10, 24, 5, 34, 20, 123456)

Convert to Timestamp

>>> pd.Timestamp(dt64)
Timestamp('2017-10-24 05:34:20.123456')

Convert from Timestamp to datetime and datetime64

This is quite easy as pandas timestamps are very powerful

>>> ts = pd.Timestamp('2017-10-24 04:24:33.654321')

>>> ts.to_pydatetime()   # Python's datetime
datetime.datetime(2017, 10, 24, 4, 24, 33, 654321)

>>> ts.to_datetime64()
numpy.datetime64('2017-10-24T04:24:33.654321000')

var arr = Array.prototype.slice.call( htmlCollection )

will have the same effect using "native" code.

Edit

Since this gets a lot of views, note (per @oriol's comment) that the following more concise expression is effectively equivalent:

var arr = [].slice.call(htmlCollection);

But note per @JussiR's comment, that unlike the "verbose" form, it does create an empty, unused, and indeed unusable array instance in the process. What compilers do about this is outside the programmer's ken.

Edit

Since ECMAScript 2015 (ES 6) there is also Array.from:

var arr = Array.from(htmlCollection);

Edit

ECMAScript 2015 also provides the spread operator, which is functionally equivalent to Array.from (although note that Array.from supports a mapping function as the second argument).

var arr = [...htmlCollection];

I've confirmed that both of the above work on NodeList.

A performance comparison for the mentioned methods: http://jsben.ch/h2IFA

Bash does not support multidimensional arrays.

You can simulate it though by using indirect expansion:

#!/bin/bash
declare -a a0=(1 2 3 4)
declare -a a1=(5 6 7 8)
var="a1[1]"
echo ${!var}  # outputs 6

Assignments are also possible with this method:

let $var=55
echo ${a1[1]}  # outputs 55

Edit 1: To read such an array from a file, with each row on a line, and values delimited by space, use this:

idx=0
while read -a a$idx; do
    let idx++;
done </tmp/some_file

Edit 2: To declare and initialize a0..a3[0..4] to 0, you could run:

for i in {0..3}; do
    eval "declare -a a$i=( $(for j in {0..4}; do echo 0; done) )"
done

I face this error on testing WebAPI in Postman tool.

After building the code, If we remove any line (For Example: In my case when I remove one Commented line this error was occur...) in debugging mode then the "Non-static method requires a target" error will occur.

Again, I tried to send the same request. This time code working properly. And I get the response properly in Postman.

I hope it will use to someone...

SOLUTION: (Notice: this solution is for datatables version 1.10.4 (at the moment) not legacy version).

CLARIFICATION Per the API documentation (1.10.15), the API can be accessed three ways:

1. The modern definition of DataTables (upper camel case):

   var datatable = $( selector ).DataTable();

2. The legacy definition of DataTables (lower camel case):

   var datatable = $( selector ).dataTable().api();

3. Using the new syntax.

   var datatable = new $.fn.dataTable.Api( selector );

Then load the data like so:

$.get('myUrl', function(newDataArray) {
    datatable.clear();
    datatable.rows.add(newDataArray);
    datatable.draw();
});

Use draw(false) to stay on the same page after the data update.

API references:

https://datatables.net/reference/api/clear()

https://datatables.net/reference/api/rows.add()

https://datatables.net/reference/api/draw()

For those who might have the same problem as me, I got this error when the DB I was using was actually master, and not the DB I should have been using.

Just put use [DBName] on the top of your script, or manually change the DB in use in the SQL Server Management Studio GUI.

coalesce is supported in both Oracle and SQL Server and serves essentially the same function as nvl and isnull. (There are some important differences, coalesce can take an arbitrary number of arguments, and returns the first non-null one. The return type for isnull matches the type of the first argument, that is not true for coalesce, at least on SQL Server.)

If you should get the following by trying decode():

AttributeError: 'str' object has no attribute 'decode'

You can also specify the encoding type straight in a cast:

>>> my_byte_str
b'Hello World'

>>> str(my_byte_str, 'utf-8')
'Hello World'

The trick is to create subclasses of ViewHolder and then cast them.

public class GroupViewHolder extends RecyclerView.ViewHolder {
    TextView mTitle;
    TextView mContent;
    public GroupViewHolder(View itemView) {
        super (itemView);
        // init views...
    }
}

public class ImageViewHolder extends RecyclerView.ViewHolder {
    ImageView mImage;
    public ImageViewHolder(View itemView) {
        super (itemView);
        // init views...
    }
}

private static final int TYPE_IMAGE = 1;
private static final int TYPE_GROUP = 2;  

And then, at runtime do something like this:

@Override
public int getItemViewType(int position) {
    // here your custom logic to choose the view type
    return position == 0 ? TYPE_IMAGE : TYPE_GROUP;
}

@Override
public void onBindViewHolder (ViewHolder viewHolder, int i) {

    switch (viewHolder.getItemViewType()) {

        case TYPE_IMAGE:
            ImageViewHolder imageViewHolder = (ImageViewHolder) viewHolder;
            imageViewHolder.mImage.setImageResource(...);
            break;

        case TYPE_GROUP:
            GroupViewHolder groupViewHolder = (GroupViewHolder) viewHolder;
            groupViewHolder.mContent.setText(...)
            groupViewHolder.mTitle.setText(...);
            break;
    }
}

Hope it helps.

Don't use srand inside the loop, use it only once, e.g. at the start of main(). And srand() is exactly how you reset this.

check the below code.

Reading from a file in the filesystem.

FileInputStream fis = null;
    try {

        fis = context.openFileInput(fileName);
        InputStreamReader isr = new InputStreamReader(fis);
        // READ STRING OF UNKNOWN LENGTH
        StringBuilder sb = new StringBuilder();
        char[] inputBuffer = new char[2048];
        int l;
        // FILL BUFFER WITH DATA
        while ((l = isr.read(inputBuffer)) != -1) {
            sb.append(inputBuffer, 0, l);
        }
        // CONVERT BYTES TO STRING
        String readString = sb.toString();
        fis.close();

    catch (Exception e) {

    } finally {
        if (fis != null) {
            fis = null;
        }
    }

below code is to write the file in to internal filesystem.

FileOutputStream fos = null;
    try {

        fos = context.openFileOutput(fileName, Context.MODE_PRIVATE);
        fos.write(stringdatatobestoredinfile.getBytes());
        fos.flush();
        fos.close();

    } catch (Exception e) {

    } finally {
        if (fos != null) {
            fos = null;
        }
    }

I think this will help you.

Here is what I do:

I press command (on Mac, probably control on PC) and then hover over the method or class. When you do this a popup window will appear with the choices "Open Declaration", "Open Implementation", "Open Return Type". You can then click on what you want and Eclipse brings you right there. I believe this works for version 3.6 and up.

It is just as quick as IntelliJ I think.

OFFICE 2013 INSTRUCTIONS:

(For Windows 7 (x64) | MS Office 32-Bit)

Option 1 | Check if ability already exists | 2 minutes

1. Open VB Editor
2. Tools -> Additional Controls
3. Select "Microsoft Monthview Control 6.0 (SP6)" (if applicable)
4. Use 'DatePicker' control for VBA Userform

Option 2 | The "Monthview" Control doesn't currently exist | 5 minutes

1. Close Excel
2. Download MSCOMCT2.cab (it's a cabinet file which extracts into two useful files)
3. Extract Both Files | the .inf file and the .ocx file
4. Install | right-click the .inf file | hit "Install"
5. Move .ocx file | Move from "C:\Windows\system32" to "C:\Windows\sysWOW64"
6. Run CMD | Start Menu -> Search -> "CMD.exe" | right-click the icon | Select "Run as administrator"
7. Register Active-X File | Type "regsvr32 c:\windows\sysWOW64\MSCOMCT2.ocx"
8. Open Excel | Open VB Editor
9. Activate Control | Tools->References | Select "Microsoft Windows Common Controls 2-6.0 (SP6)"
10. Userform Controls | Select any userform in VB project | Tools->Additional Controls
11. Select "Microsoft Monthview Control 6.0 (SP6)"
12. Use 'DatePicker' control for VBA UserForm

Okay, either of these two steps should work for you if you have Office 2013 (32-Bit) on Windows 7 (x64). Some of the steps may be different if you have a different combo of Windows 7 & Office 2013.

The "Monthview" control will be your fully fleshed out 'DatePicker'. It comes equipped with its own properties and image. It works very well. Good luck.

You could use flatMap. It can filter and map in one.

$scope.appIds = $scope.applicationsHere.flatMap(obj => obj.selected ? obj.id : [])

Here's how to pick a random sample out of each group:

SELECT GROUPING_COLUMN, 
       MIN (COLUMN_NAME) KEEP (DENSE_RANK FIRST ORDER BY DBMS_RANDOM.VALUE) 
         AS RANDOM_SAMPLE
FROM TABLE_NAME
GROUP BY GROUPING_COLUMN
ORDER BY GROUPING_COLUMN;

I'm not sure how efficient it is, but if you have a lot of categories and sub-categories, this seems to do the job nicely.

public static LocalTime time() {
    LocalTime ldt = java.time.LocalTime.now();

    ldt = ldt.truncatedTo(ChronoUnit.MINUTES);
    System.out.println(ldt);
    return ldt;
}

This works for me

First, you need to understand the difference between window and document. The window object is a top level client side object. There is nothing above the window object. JavaScript is an object orientated language. You start with an object and apply methods to its properties or the properties of its object groups. For example, the document object is an object of the window object. To change the document's background color, you'd set the document's bgcolor property.

window.document.bgcolor = "red" 

To answer your question, There is no difference in the end result between window and document scrollTop. Both will give the same output.

Check working example at http://jsfiddle.net/7VRvj/6/

In general use document mainly to register events and use window to do things like scroll, scrollTop, and resize.

Why is 21 the default port for FTP? Or 80 the default for HTTP? It is a convention.

Check your content-type in the header. I was having issue with this sending raw JSON and my content-type as application/json in the POSTMAN header.

my php was seeing jack all in the request post. It wasn't until i change the content-type to application/x-www-form-urlencoded with the JSON in the RAW textarea and its type as JSON, did my PHP app start to see the post data. not what i expected when deal with raw json but its now working for what i need.

Old question, but I have an answer.

First, peruse the elements of the list like so:

for x in range(len(yourlist)):
    print '%s: %s' % (x, yourlist[x])

Then, call this function with a list of the indexes of elements you want to pop. It's robust enough that the order of the list doesn't matter.

def multipop(yourlist, itemstopop):
    result = []
    itemstopop.sort()
    itemstopop = itemstopop[::-1]
    for x in itemstopop:
        result.append(yourlist.pop(x))
    return result

As a bonus, result should only contain elements you wanted to remove.

In [73]: mylist = ['a','b','c','d','charles']

In [76]: for x in range(len(mylist)):

      mylist[x])

....:

0: a

1: b

2: c

3: d

4: charles

...

In [77]: multipop(mylist, [0, 2, 4])

Out[77]: ['charles', 'c', 'a']

...

In [78]: mylist

Out[78]: ['b', 'd']

You can truncate the date part:

select * from table1 where trunc(field1) = to_date('2012-01-01', 'YYYY-MM-DD')

The trouble with this approach is that any index on field1 wouldn't be used due to the function call.

Alternatively (and more index friendly)

select * from table1 
 where field1 >= to_timestamp('2012-01-01', 'YYYY-MM-DD') 
   and field1 < to_timestamp('2012-01-02', 'YYYY-MM-DD')

To me it sounds like the simplest way to expose your git repository on the server (which seems to be a Windows machine) would be to share it as a network resource.

Right click the folder "MY_GIT_REPOSITORY" and select "Sharing". This will give you the ability to share your git repository as a network resource on your local network. Make sure you give the correct users the ability to write to that share (will be needed when you and your co-workers push to the repository).

The URL for the remote that you want to configure would probably end up looking something like file://\\\\189.14.666.666\MY_GIT_REPOSITORY

If you wish to use any other protocol (e.g. HTTP, SSH) you'll have to install additional server software that includes servers for these protocols. In lieu of these the file sharing method is probably the easiest in your case right now.

def splitter(A):
    B = A[0:len(A)//2]
    C = A[len(A)//2:]

 return (B,C)

I tested, and the double slash is required to force int division in python 3. My original post was correct, although wysiwyg broke in Opera, for some reason.

You need to use padding on the list item layout so space is added on the edges of the item (just increasing the font size won't do that).

<?xml version="1.0" encoding="utf-8"?>
<TextView android:id="@+id/text1"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:padding="8dp" />

J2V8 is best solution of your problem. It's run Nodejs application on jvm(java and android).

J2V8 is Java Bindings for V8, But Node.js integration is available in J2V8 (version 4.4.0)

Github : https://github.com/eclipsesource/J2V8

Example : http://eclipsesource.com/blogs/2016/07/20/running-node-js-on-the-jvm/

java.util.Date represents a specific instant in time with millisecond precision. It represents both date and time information without timezone. The java.util.Date class implements Serializable, Cloneable and Comparable interface. It is inherited by java.sql.Date, java.sql.Time and java.sql.Timestamp interfaces.

java.sql.Date extends java.util.Date class which represents date without time information and it should be used only when dealing with databases. To conform with the definition of SQL DATE, the millisecond values wrapped by a java.sql.Date instance must be 'normalized' by setting the hours, minutes, seconds, and milliseconds to zero in the particular time zone with which the instance is associated.

It inherits all public methods of java.util.Date such as getHours(), getMinutes(), getSeconds(), setHours(), setMinutes(), setSeconds(). As java.sql.Date does not store the time information, it override all the time operations from java.util.Dateand all of these methods throw java.lang.IllegalArgumentException if invoked as evident from their implementation details.

You might also be interested in https://github.com/phadej/igbinary - which provides a different serialization 'engine' for PHP.

My random/arbitrary 'performance' figures, using PHP 5.3.5 on a 64bit platform show :

JSON :

• JSON encoded in 2.180496931076 seconds
• JSON decoded in 9.8368630409241 seconds
• serialized "String" size : 13993

Native PHP :

• PHP serialized in 2.9125759601593 seconds
• PHP unserialized in 6.4348418712616 seconds
• serialized "String" size : 20769

Igbinary :

• WIN igbinary serialized in 1.6099879741669 seconds
• WIN igbinrary unserialized in 4.7737920284271 seconds
• WIN serialized "String" Size : 4467

So, it's quicker to igbinary_serialize() and igbinary_unserialize() and uses less disk space.

I used the fillArray(0, 3) code as above, but made the array keys longer strings.

igbinary can store the same data types as PHP's native serialize can (So no problem with objects etc) and you can tell PHP5.3 to use it for session handling if you so wish.

For me, I wanted a string representation unless it was null, in which case I wanted it to remain null.

The problem with var_export is it converts null to a string "NULL" and it also converts an empty string to "''", which is undesirable. There was no easy solution that I could find.

This was the code I finally used:

if (is_bool($val)) $val ? $val = "true" : $val = "false";
else if ($val !== null) $val = (string)$val;

Short and simple and easy to throw in a function too if you prefer.

Not all collections have indexes. For instance, I can use a Dictionary with foreach (and iterate through all the keys and values), but I can't write get at individual elements using dictionary[0], dictionary[1] etc.

If I did want to iterate through a dictionary and keep track of an index, I'd have to use a separate variable that I incremented myself.
