This might not be the exact thing you are looking for, but you can create a very similar effect by using rgba in combination with linear-gradient:

  background: linear-gradient(rgba(0,0,0,.5) 0%, rgba(0,0,0,0) 30%);

This creates a linear-gradient from black with 50% opacity (rgba(0,0,0,.5)) to transparent (rgba(0,0,0,0)) which starts being competently transparent 30% from the top. You can play with those values to create your desired effect. You can have it on a different side by adding a deg-value (linear-gradient(90deg, rgba(0,0,0,.5) 0%, rgba(0,0,0,0) 30%)) or switching the colors around. If you want really complex shadows like different angles on different sides you could even start layering linear-gradient.

Here is a snippet to see it in action:

.box {_x000D_
  background: linear-gradient(rgba(0,0,0,.5) 0%, rgba(0,0,0,0) 30%);_x000D_
}_x000D_
_x000D_
.text {_x000D_
  padding: 20px;_x000D_
}

<div class="box">_x000D_
  <div class="text">_x000D_
    Lorem ipsum ...._x000D_
  </div>_x000D_
</div>

TestCocoon is also pretty nice. It is in active development and has a user community:

• Open source (GPL 3)
• Supports C/C++/C# cross platform (Linux, Windows, and Mac)
• CoverageScanner - Instrumentation during the Generation
• CoverageBrowser - View, Analysis and Management of Code Coverage Result

However, TestCocoon is no longer developed and its creators are now producing a commercial software for C/C++.

I interpreted the question as using cast on a subquery. Yes, you can do that:

select cast((<subquery>) as <newtype>)

If you do so, then you need to be sure that the returns one row and one value. And, since it returns one value, you could put the cast in the subquery instead:

select (select cast(<val> as <newtype>) . . .)

You can look at outline with offset but this needs some padding to exists on your div. Or you can absolutely position a border div inside, something like

<div id='parentDiv' style='position:relative'>
  <div id='parentDivsContent'></div>
  <div id='fakeBordersDiv' 
       style='position: absolute;width: 100%;
              height: 100%;
              z-index: 2;
              border: 2px solid;
              border-radius: 2px;'/>
</div>

You might need to fiddle with margins on the fake borders div to fit it as you like.

Code on Github

sample : you can use :

           string login = "";
           string domain = "";
           string password = "";

           using (UserImpersonation user = new UserImpersonation(login, domain, password))
           {
               if (user.ImpersonateValidUser())
               {
                   File.WriteAllText("test.txt", "your text");
                   Console.WriteLine("File writed");
               }
               else
               {
                   Console.WriteLine("User not connected");
               }
           }

It is possible in Python 3 since v3.1 and Python 2.7. The new with syntax supports multiple context managers:

with A() as a, B() as b, C() as c:
    doSomething(a,b,c)

Unlike the contextlib.nested, this guarantees that a and b will have their __exit__()'s called even if C() or it's __enter__() method raises an exception.

You can also use earlier variables in later definitions (h/t Ahmad below):

with A() as a, B(a) as b, C(a, b) as c:
    doSomething(a, c)

Try to slightly modify your code:

Sub forEachWs()
    Dim ws As Worksheet
    For Each ws In ActiveWorkbook.Worksheets
        Call resizingColumns(ws)
    Next
End Sub

Sub resizingColumns(ws As Worksheet)
    With ws
        .Range("A:A").ColumnWidth = 20.14
        .Range("B:B").ColumnWidth = 9.71
        .Range("C:C").ColumnWidth = 35.86
        .Range("D:D").ColumnWidth = 30.57
        .Range("E:E").ColumnWidth = 23.57
        .Range("F:F").ColumnWidth = 21.43
        .Range("G:G").ColumnWidth = 18.43
        .Range("H:H").ColumnWidth = 23.86
        .Range("i:I").ColumnWidth = 27.43
        .Range("J:J").ColumnWidth = 36.71
        .Range("K:K").ColumnWidth = 30.29
        .Range("L:L").ColumnWidth = 31.14
        .Range("M:M").ColumnWidth = 31
        .Range("N:N").ColumnWidth = 41.14
        .Range("O:O").ColumnWidth = 33.86
    End With
End Sub

Note, resizingColumns routine takes parametr - worksheet to which Ranges belongs.

Basically, when you're using Range("O:O") - code operats with range from ActiveSheet, that's why you should use With ws statement and then .Range("O:O").

And there is no need to use global variables (unless you are using them somewhere else)

An example of Python's way of doing "ternary" expressions:

i = 5 if a > 7 else 0

translates into

if a > 7:
   i = 5
else:
   i = 0

This actually comes in handy when using list comprehensions, or sometimes in return statements, otherwise I'm not sure it helps that much in creating readable code.

The readability issue was discussed at length in this recent SO question better way than using if-else statement in python.

It also contains various other clever (and somewhat obfuscated) ways to accomplish the same task. It's worth a read just based on those posts.

In cases like that there is a quick and dirty solution using arrays with one element:

public void swap(int[] a, int[] b) {
  int temp = a[0];
  a[0] = b[0];
  b[0] = temp;
}

Of course your code has to work with these arrays too, which is inconvenient. The array trick is more useful if you want to modify a local final variable from an inner class:

public void test() {
  final int[] a = int[]{ 42 };  
  new Thread(new Runnable(){ public void run(){ a[0] += 10; }}).start();
  while(a[0] == 42) {
    System.out.println("waiting...");   
  }
  System.out.println(a[0]);   
} 

User.hasMany(Post, {foreignKey: 'user_id'})
Post.belongsTo(User, {foreignKey: 'user_id'})

Post.find({ where: { ...}, include: [User]})

Which will give you

SELECT
  `posts`.*,
  `users`.`username` AS `users.username`, `users`.`email` AS `users.email`,
  `users`.`password` AS `users.password`, `users`.`sex` AS `users.sex`,
  `users`.`day_birth` AS `users.day_birth`,
  `users`.`month_birth` AS `users.month_birth`,
  `users`.`year_birth` AS `users.year_birth`, `users`.`id` AS `users.id`,
  `users`.`createdAt` AS `users.createdAt`,
  `users`.`updatedAt` AS `users.updatedAt`
FROM `posts`
  LEFT OUTER JOIN `users` AS `users` ON `users`.`id` = `posts`.`user_id`;

The query above might look a bit complicated compared to what you posted, but what it does is basically just aliasing all columns of the users table to make sure they are placed into the correct model when returned and not mixed up with the posts model

Other than that you'll notice that it does a JOIN instead of selecting from two tables, but the result should be the same

I guess you have overridden the builtin function/variable or something else "module" by setting the global variable "module". just print the module see whats in it.

Make sure you have all the required software to run node-gyp:

• https://github.com/TooTallNate/node-gyp

You can configure version of Visual Studio used by node-gyp via an environment variable so you can avoid having to set the --msvs_version=2012 property every time you do an npm install.

Examples:

• set GYP_MSVS_VERSION=2012 for Visual Studio 2012
• set GYP_MSVS_VERSION=2013e (the 'e' stands for FREE 'express edition')

For the full list see - https://github.com/joyent/node/blob/v0.10.29/tools/gyp/pylib/gyp/MSVSVersion.py#L209-294

This is still painful for Windows users of NodeJS as it assumes you have a copy of Visual Studio installed and many end users will never have this. So I'm lobbying Joyent to the encourage them to include web sockets as part of CORE node and also to possible ship a GNU gcc compiler as part of NodeJS install so we can permanently fix this problem.

ok, so if you are using bootstrap-rtl.css, what you can do is go to the following class .modal-backdrop and remove the z-index attribute. after that all should be fine

Yes, the syntax is accurate and it should be fine.

Here is the SQL Fiddle Demo I created for your particular case

create table sample2
(
    id int primary key,
    created_date date,
    data varchar(10)
  )

insert into sample2 values (1,'2012-01-01','testing');

And here is how to select the data

SELECT Created_Date
FROM sample2
WHERE Created_Date >= DATEADD(day,-11117, GETDATE())

If You want to parse PDF using Python please have a look at PDFMINER. This is the best library to parse PDF files till date.

One of the problem with this code is here :

name += contactName[];

This instruction won't insert anything in the array. Instead it will concatenate the current value of the variable name with the string representation of the contactName array.

Instead use this:

contactName[index] = name;

this instruction will store the variable name in the contactName array at the index index.

The second problem you have is that you don't have the variable index.

What you can do is a loop with 12 iterations to fill all your arrays. (and index will be your iteration variable)

JavaScript

$.listen('click', '#captcha', function() {
    $('#captcha-block').html('<div id="loading" style="width: 70px; height: 40px; display: inline-block;" />');
    $.get("/captcha/new", null, function(data) {
        $('#captcha-block').html(data);
    }); 
    return false;
});

It seems like a Android Runtime bug. There seems to be finalizer that runs in its separate thread and calls finalize() method on objects if they are not in the current frame of the stacktrace. For example following code(created to verify this issue) ended with the crash.

Let's have some cursor that do something in finalize method(e.g. SqlCipher ones, do close() which locks to the database that is currently in use)

private static class MyCur extends MatrixCursor {


    public MyCur(String[] columnNames) {
        super(columnNames);
    }

    @Override
    protected void finalize() {
        super.finalize();

        try {
            for (int i = 0; i < 1000; i++)
                Thread.sleep(30);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

And we do some long running stuff having opened cursor:

for (int i = 0; i < 7; i++) {
        new Thread(new Runnable() {
            @Override
            public void run() {
                MyCur cur = null;
                try {
                    cur = new MyCur(new String[]{});
                    longRun();
                } finally {
                    cur.close();
                }
            }

            private void longRun() {
                try {
                    for (int i = 0; i < 1000; i++)
                        Thread.sleep(30);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }).start();
    }

This causes following error:

Resume: Close cursors ASAP. At least on Samsung S8 with Android 7 where the issue have been seen.

Copying and pasting from the MS-DOS tree command might also work for you. Examples:

¦   +---Drop
...

Syntax ^[source]

tree [drive:][path] [/F] [/A]

drive:\path — Drive and directory containing disk for display of directory structure, without listing files.

/F — Include all files living in every directory.

/A — Replace graphic characters used for linking lines with ext characters , instead of graphic characters. /a is used with code pages that do not support graphic characters and to send output to printers that do not properly interpret graphic characters.

MVC's anti-forgery support writes a unique value to an HTTP-only cookie and then the same value is written to the form. When the page is submitted, an error is raised if the cookie value doesn't match the form value.

It's important to note that the feature prevents cross site request forgeries. That is, a form from another site that posts to your site in an attempt to submit hidden content using an authenticated user's credentials. The attack involves tricking the logged in user into submitting a form, or by simply programmatically triggering a form when the page loads.

The feature doesn't prevent any other type of data forgery or tampering based attacks.

To use it, decorate the action method or controller with the ValidateAntiForgeryToken attribute and place a call to @Html.AntiForgeryToken() in the forms posting to the method.

We don't know what server.properties file is that, we neither know what SimocoPoolSize means (do you?)

Let's guess you are using some custom pool of database connections. Then, I guess the problem is that your pool is configured to open 100 or 120 connections, but you Postgresql server is configured to accept MaxConnections=90 . These seem conflictive settings. Try increasing MaxConnections=120.

But you should first understand your db layer infrastructure, know what pool are you using, if you really need so many open connections in the pool. And, specially, if you are gracefully returning the opened connections to the pool

This worked for me.

// strip tags to avoid breaking any html
$string = strip_tags($string);
if (strlen($string) > 500) {

    // truncate string
    $stringCut = substr($string, 0, 500);
    $endPoint = strrpos($stringCut, ' ');

    //if the string doesn't contain any space then it will cut without word basis.
    $string = $endPoint? substr($stringCut, 0, $endPoint) : substr($stringCut, 0);
    $string .= '... <a href="/this/story">Read More</a>';
}
echo $string;

Thanks @webbiedave

There is a simple why that I prefered to the bundle due to the no duplicate data in memory. It consists of a init public method for the fragment

private ArrayList<Music> listMusics = new ArrayList<Music>();
private ListView listMusic;


public static ListMusicFragment createInstance(List<Music> music) {
    ListMusicFragment fragment = new ListMusicFragment();
    fragment.init(music);
    return fragment;
}

public void init(List<Music> music){
    this.listMusic = music;
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
    Bundle savedInstanceState)
{

    View view = inflater.inflate(R.layout.musiclistview, container, false);
    listMusic = (ListView) view.findViewById(R.id.musicListView);
    listMusic.setAdapter(new MusicBaseAdapter(getActivity(), listMusics));

    return view;
}
}

In two words, you create an instance of the fragment an by the init method (u can call it as u want) you pass the reference of your list without create a copy by serialization to the instance of the fragment. This is very usefull because if you change something in the list u will get it in the other parts of the app and ofcourse, you use less memory.

You can do it very easily with a Cloud Management software -like enStratus, RightScale or Scalr (disclaimer: I work there). With the cloned farm you can:

1. Create a snapshot or a pre-made image to launch another day
2. Duplicate your configuration to test it before production

       NSInteger SelectedRow;
                   SelectedRow = [yourPickerView selectedRowInComponent:0];
                   selectedPickerString = [YourPickerArray objectAtIndex:SelectedRow];
                   self.YourTextField.text= selectedPickerString;

    // if  you want to move pickerview to selected row then 
 for (int i = 0; I<YourPickerArray.count; i++) {
  if ([[YourPickerArray objectAtIndex:i] isEqualToString:self.YourTextField.text]) { 
[yourPickerView selectRow:i inComponent:0 animated:NO];
 }
}

Use the --force (-f) flag on your mysql import. Rather than stopping on the offending statement, MySQL will continue and just log the errors to the console.

For example:

mysql -u userName -p -f -D dbName < script.sql

It sounds like Apache is warning you that you have multiple <VirtualHost> sections with the same IP address and port... as far as getting it to work without warnings, I think you would need to use something like Server Name Indication (SNI), a way of identifying the hostname requested as part of the SSL handshake. Basically it lets you do name-based virtual hosting over SSL, but I'm not sure how well it's supported by browsers. Other than something like SNI, you're basically limited to one SSL-enabled domain name for each IP address you expose to the public internet.

Of course, if you are able to access the websites properly, you'll probably be fine ignoring the warnings. These particular ones aren't very serious - they're mainly an indication of what to look at if you are experiencing problems

The methods in the other answers will not work properly when the yticks are large. The ylabel will either overlap with ticks, be clipped on the left or completely invisible/outside of the figure.

I've modified Hagne's answer so it works with more than 1 column of subplots, for both xlabel and ylabel, and it shifts the plot to keep the ylabel visible in the figure.

def set_shared_ylabel(a, xlabel, ylabel, labelpad = 0.01, figleftpad=0.05):
    """Set a y label shared by multiple axes
    Parameters
    ----------
    a: list of axes
    ylabel: string
    labelpad: float
        Sets the padding between ticklabels and axis label"""

    f = a[0,0].get_figure()
    f.canvas.draw() #sets f.canvas.renderer needed below

    # get the center position for all plots
    top = a[0,0].get_position().y1
    bottom = a[-1,-1].get_position().y0

    # get the coordinates of the left side of the tick labels
    x0 = 1
    x1 = 1
    for at_row in a:
        at = at_row[0]
        at.set_ylabel('') # just to make sure we don't and up with multiple labels
        bboxes, _ = at.yaxis.get_ticklabel_extents(f.canvas.renderer)
        bboxes = bboxes.inverse_transformed(f.transFigure)
        xt = bboxes.x0
        if xt < x0:
            x0 = xt
            x1 = bboxes.x1
    tick_label_left = x0

    # shrink plot on left to prevent ylabel clipping
    # (x1 - tick_label_left) is the x coordinate of right end of tick label,
    # basically how much padding is needed to fit tick labels in the figure
    # figleftpad is additional padding to fit the ylabel
    plt.subplots_adjust(left=(x1 - tick_label_left) + figleftpad)

    # set position of label, 
    # note that (figleftpad-labelpad) refers to the middle of the ylabel
    a[-1,-1].set_ylabel(ylabel)
    a[-1,-1].yaxis.set_label_coords(figleftpad-labelpad,(bottom + top)/2, transform=f.transFigure)

    # set xlabel
    y0 = 1
    for at in axes[-1]:
        at.set_xlabel('')  # just to make sure we don't and up with multiple labels
        bboxes, _ = at.xaxis.get_ticklabel_extents(fig.canvas.renderer)
        bboxes = bboxes.inverse_transformed(fig.transFigure)
        yt = bboxes.y0
        if yt < y0:
            y0 = yt
    tick_label_bottom = y0

    axes[-1, -1].set_xlabel(xlabel)
    axes[-1, -1].xaxis.set_label_coords((left + right) / 2, tick_label_bottom - labelpad, transform=fig.transFigure)

It works for the following example, while Hagne's answer won't draw ylabel (since it's outside of the canvas) and KYC's ylabel overlaps with the tick labels:

import matplotlib.pyplot as plt
import itertools

fig, axes = plt.subplots(3, 4, sharey='row', sharex=True, squeeze=False)
fig.subplots_adjust(hspace=.5)
for i, a in enumerate(itertools.chain(*axes)):
    a.plot([0,4**i], [0,4**i])
    a.set_title(i)
set_shared_ylabel(axes, 'common X', 'common Y')
plt.show()

Alternatively, if you are fine with colorless axis, I've modified Julian Chen's solution so ylabel won't overlap with tick labels.

Basically, we just have to set ylims of the colorless so it matches the largest ylims of the subplots so the colorless tick labels sets the correct location for the ylabel.

Again, we have to shrink the plot to prevent clipping. Here I've hard coded the amount to shrink, but you can play around to find a number that works for you or calculate it like in the method above.

import matplotlib.pyplot as plt
import itertools

fig, axes = plt.subplots(3, 4, sharey='row', sharex=True, squeeze=False)
fig.subplots_adjust(hspace=.5)
miny = maxy = 0
for i, a in enumerate(itertools.chain(*axes)):
    a.plot([0,4**i], [0,4**i])
    a.set_title(i)
    miny = min(miny, a.get_ylim()[0])
    maxy = max(maxy, a.get_ylim()[1])

# add a big axes, hide frame
# set ylim to match the largest range of any subplot
ax_invis = fig.add_subplot(111, frameon=False)
ax_invis.set_ylim([miny, maxy])

# hide tick and tick label of the big axis
plt.tick_params(labelcolor='none', top=False, bottom=False, left=False, right=False)
plt.xlabel("common X")
plt.ylabel("common Y")

# shrink plot to prevent clipping
plt.subplots_adjust(left=0.15)
plt.show()

ord() will not work because your end string is two characters long.

Returns the ASCII value of the first character of string.

Watch it break.

From my testing, you need to check that the end string doesn't get "stepped over". The perl-style character incrementation is a cool method, but it is a single-stepping method. For this reason, an inner loop helps it along when necessary. This is actually not a bother, in fact, it is useful because we need to check if the loop(s) should be broken on each single step.

Code: (Demo)

function excelCols($letter,$end,$step=1){  // function doesn't check that $end is "later" than $letter
    if($step==0)return [];  // prevent infinite loop
    do{
        $letters[]=$letter;  // store letter
        for($x=0; $x<$step; ++$x){  // increment in accordance with $step declaration
            if($letter===$end)break(2);  // break if end is "stepped on"
            ++$letter;
        }
    }while(true);
    return $letters;    
}
echo implode(' ',excelCols('A','JJ',4));
echo "\n --- \n";
echo implode(' ',excelCols('A','BB',3));
echo "\n --- \n";
echo implode(' ',excelCols('A','ZZ',1));
echo "\n --- \n";
echo implode(' ',excelCols('A','ZZ',3));

Here is an array-functions approach:

Code: (Demo)

$start='C';
$end='DD';
$step=4;

// generate and store more than we need (this is an obvious method disadvantage)
$result=$array=range('A','Z',1);  // store A - Z as $array and $result
foreach($array as $a){
    foreach($array as $b){
        $result[]="$a$b";  // store double letter combinations
        if(in_array($end,$result)){break(2);}  // stop asap
    }
}
//echo implode(' ',$result),"\n\n";

// slice away from the front of the array
$result=array_slice($result,array_search($start,$result));  // reindex keys
//echo implode(' ',$result),"\n\n";

 // punch out elements that are not "stepped on"
$result=array_filter($result,function($k)use($step){return $k%$step==0;},ARRAY_FILTER_USE_KEY); // use modulo

// result is ready
echo implode(' ',$result);

I use varargs frequently for constructors that can take some sort of filter object. For example, a large part of our system based on Hadoop is based on a Mapper that handles serialization and deserialization of items to JSON, and applies a number of processors that each take an item of content and either modify and return it, or return null to reject.

How about something like this...

Dim rs As RecordSet
Set rs = Currentdb.OpenRecordSet("SELECT PictureLocation, ID FROM MyAccessTable;")

Do While Not rs.EOF
   Debug.Print rs("PictureLocation") & " - " & rs("ID")
   rs.MoveNext
Loop

app.use
is created by express(nodejs middleware framework )
app.use is use to execute any specific query at intilization process
server.js(node)
var app = require('express');
app.use(bodyparser.json())
so the basically app.use function called every time when server up

For the lazy and the learning, to put it into your theme, Rfvgyhn's full code

<?php $category = get_the_category();
$firstCategory = $category[0]->cat_name; echo $firstCategory;?>

You can use jQuery grep and push if no results: http://api.jquery.com/jQuery.grep/

It's basically the same solution as in the "extending the prototype" solution, but without extending (or polluting) the prototype.

MSDN Documentation Here

To add a bit of context to M.Ali's Answer you can convert a string to a uniqueidentifier using the following code

   SELECT CONVERT(uniqueidentifier,'DF215E10-8BD4-4401-B2DC-99BB03135F2E')

If that doesn't work check to make sure you have entered a valid GUID

In SQL SERVER, this is the answer

Declare @t table(TITLE VARCHAR(100), DESCRIPTION VARCHAR(100))

INSERT INTO @t SELECT 'test1', 'value blah blah value' 
INSERT INTO @t SELECT 'test2','value test' 
INSERT INTO @t SELECT 'test3','test test test' 
INSERT INTO @t SELECT 'test4','valuevaluevaluevaluevalue' 


SELECT TITLE,DESCRIPTION,Count = (LEN(DESCRIPTION) - LEN(REPLACE(DESCRIPTION, 'value', '')))/LEN('value') 

FROM @t

Result

TITLE   DESCRIPTION               Count
test1   value blah blah value        2
test2   value test                   1
test3   test test test               0
test4   valuevaluevaluevaluevalue    5

I don't have MySQL install, but goggled to find the Equivalent of LEN is LENGTH while REPLACE is same.

So the equivalent query in MySql should be

SELECT TITLE,DESCRIPTION, (LENGTH(DESCRIPTION) - LENGTH(REPLACE(DESCRIPTION, 'value', '')))/LENGTH('value') AS Count
FROM <yourTable>

Please let me know if it worked for you in MySql also.

std::atomic exists because many ISAs have direct hardware support for it

What the C++ standard says about std::atomic has been analyzed in other answers.

So now let's see what std::atomic compiles to to get a different kind of insight.

The main takeaway from this experiment is that modern CPUs have direct support for atomic integer operations, for example the LOCK prefix in x86, and std::atomic basically exists as a portable interface to those intructions: What does the "lock" instruction mean in x86 assembly? In aarch64, LDADD would be used.

This support allows for faster alternatives to more general methods such as std::mutex, which can make more complex multi-instruction sections atomic, at the cost of being slower than std::atomic because std::mutex it makes futex system calls in Linux, which is way slower than the userland instructions emitted by std::atomic, see also: Does std::mutex create a fence?

Let's consider the following multi-threaded program which increments a global variable across multiple threads, with different synchronization mechanisms depending on which preprocessor define is used.

main.cpp

#include <atomic>
#include <iostream>
#include <thread>
#include <vector>

size_t niters;

#if STD_ATOMIC
std::atomic_ulong global(0);
#else
uint64_t global = 0;
#endif

void threadMain() {
    for (size_t i = 0; i < niters; ++i) {
#if LOCK
        __asm__ __volatile__ (
            "lock incq %0;"
            : "+m" (global),
              "+g" (i) // to prevent loop unrolling
            :
            :
        );
#else
        __asm__ __volatile__ (
            ""
            : "+g" (i) // to prevent he loop from being optimized to a single add
            : "g" (global)
            :
        );
        global++;
#endif
    }
}

int main(int argc, char **argv) {
    size_t nthreads;
    if (argc > 1) {
        nthreads = std::stoull(argv[1], NULL, 0);
    } else {
        nthreads = 2;
    }
    if (argc > 2) {
        niters = std::stoull(argv[2], NULL, 0);
    } else {
        niters = 10;
    }
    std::vector<std::thread> threads(nthreads);
    for (size_t i = 0; i < nthreads; ++i)
        threads[i] = std::thread(threadMain);
    for (size_t i = 0; i < nthreads; ++i)
        threads[i].join();
    uint64_t expect = nthreads * niters;
    std::cout << "expect " << expect << std::endl;
    std::cout << "global " << global << std::endl;
}

• the non-atomic version saves the global to a register, and increments the register.

  Therefore, at the end, very likely four writes happen back to global with the same "wrong" value of 100000.

• std::atomic compiles to lock addq. The LOCK prefix makes the following inc fetch, modify and update memory atomically.

• our explicit inline assembly LOCK prefix compiles to almost the same thing as std::atomic, except that our inc is used instead of add. Not sure why GCC chose add, considering that our INC generated a decoding 1 byte smaller.

I face the same problem. After reading numerous posts, I would like to introduce the following solution I finally chose over many other methods (e.g. use urllib, httpimport, clone from GitHub, package the modules for installation, etc). The solution utilizes Google Drive API (official doc) for proper authorization.

Advantages:

1. Easy and safe (no need for code to handle file operation exceptions and/or additional authorization)
2. Module files safeguarded by Google account credentials (no one else can view/take/edit them)
3. You control what to upload/access (you can change/revoke access anytime on a file-by-file basis)
4. Everything in one place (no need to rely upon or manage another file hosting service)
5. Freedom to rename/relocate module files (not path-based and won't break your/other's notebook code)

Steps:

1. Save your .py module file to Google Drive - you should have that since you're already using Colab
2. Right click on it, "Get shareable link", copy the part after "id=" - the file id assigned by Google Drive
3. Add and run the following code snippets to your Colab notebook:

!pip install pydrive                             # Package to use Google Drive API - not installed in Colab VM by default
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive

from google.colab import auth                    # Other necessary packages
from oauth2client.client import GoogleCredentials

auth.authenticate_user()                         # Follow prompt in the authorization process
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()

drive = GoogleDrive(gauth)
your_module = drive.CreateFile({"id": "your_module_file_id"})   # "your_module_file_id" is the part after "id=" in the shareable link
your_module.GetContentFile("your_module_file_name.py")          # Save the .py module file to Colab VM
import your_module_file_name                                    # Ready to import. Don't include".py" part, of course :)

Side note

Last but not least, I should credit the original contributor of this approach. That post might have some typo in the code as it triggered an error when I tried it. After more reading and troubleshooting my code snippets above worked (as of today on Colab VM OS: Linux 4.14.79).

"svn co --username=yourUserName --password=yourpassword http://path-to-your-svn"

Worked for me when on another user account. You will be prompted to enter username/password again though. You need to login like the above once and you are all set for the subsequent times(Unless you restart your machine).

After you edit /etc/php5/apache2/php.ini be sure to restart apache.

You can do so by running:

sudo service apache2 restart

Also in Spring boot 1.4, you can add following lines to your application.properties to set the file size limit:

spring.http.multipart.max-file-size=128KB
spring.http.multipart.max-request-size=128KB

for spring boot 2.x and above its

spring.servlet.multipart.max-file-size=10MB
spring.servlet.multipart.max-request-size=10MB

Worked for me. Source: https://spring.io/guides/gs/uploading-files/

UPDATE:

Somebody asked the differences between the two properties.

Below are the formal definitions:

MaxFileSize: The maximum size allowed for uploaded files, in bytes. If the size of any uploaded file is greater than this size, the web container will throw an exception (IllegalStateException). The default size is unlimited.

MaxRequestSize: The maximum size allowed for a multipart/form-data request, in bytes. The web container will throw an exception if the overall size of all uploaded files exceeds this threshold. The default size is unlimited.

To explain each:

MaxFileSize: The limit for a single file to upload. This is applied for the single file limit only.

MaxRequestSize: The limit for the total size of all files in a single upload request. This checks the total limit. Let's say you have two files a.txt and b.txt for a single upload request. a.txt is 5kb and b.txt is 7kb so the MaxRequestSize should be above 12kb.

To run a URL simply use command below easy yess CPanel 100%

/usr/bin/php -q /home/CpanelUsername/public_html/RootFolder/cronjob/fetch.php

I hope this help.

One way is that In case of Session Expire, in every action you have to check its session and if it is null then redirect to Login page.

But this is very hectic method To over come this you need to create your own ActionFilterAttribute which will do this, you just need to add this attribute in every action method.

Here is the Class which overrides ActionFilterAttribute.

public class SessionExpireFilterAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            HttpContext ctx = HttpContext.Current;

            // check if session is supported
            CurrentCustomer objCurrentCustomer = new CurrentCustomer();
            objCurrentCustomer = ((CurrentCustomer)SessionStore.GetSessionValue(SessionStore.Customer));
            if (objCurrentCustomer == null)
            {
                // check if a new session id was generated
                filterContext.Result = new RedirectResult("~/Users/Login");
                return;
            }

            base.OnActionExecuting(filterContext);
        }
    }

Then in action just add this attribute like so:

[SessionExpire]
public ActionResult Index()
{
     return Index();
}

This will do you work.

The easiest is

as @greggo pointed out

string="mystring";
string[:-1]

{
    dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
}
dataGridView1.Columns[dataGridView1.Columns.Count - 1].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
    int colw = dataGridView1.Columns[i].Width;
    dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
    dataGridView1.Columns[i].Width = colw;
}

Prerequisites: You already have the service and published WSDL file, and you want to call your web service from C# client application.

There are 2 main way of doing this:

A) ASP.NET services, which is old way of doing SOA
B) WCF, as John suggested, which is the latest framework from MS and provides many protocols, including open and MS proprietary ones.

Adding a service reference step by step

The simplest way is to generate proxy classes in C# application (this process is called adding service reference).

1. Open your project (or create a new one) in visual studio
2. Right click on the project (on the project and not the solution) in Solution Explorer and click Add Service Reference

3. A dialog should appear shown in screenshot below. Enter the url of your wsdl file and hit Ok. Note that if you'll receive error message after hitting ok, try removing ?wsdl part from url.

   

   I'm using http://www.dneonline.com/calculator.asmx?WSDL as an example

4. Expand Service References in Solution Explorer and double click CalculatorServiceReference (or whatever you named the named the service in the previous step).

   You should see generated proxy class name and namespace.

   In my case, the namespace is SoapClient.CalculatorServiceReference, the name of proxy class is CalculatorSoapClient. As I said above, class names may vary in your case.

   

5. Go to your C# source code and add the following

   using WindowsFormsApplication1.ServiceReference1
   

6. Now you can call the service this way.

   Service1Client service = new Service1Client();
   int year = service.getCurrentYear();
   

Hope this helps. If you encounter any problems, let us know.

The first option should sufice: http://jsfiddle.net/sFCg3/

jQuery('#autoship_option').val('');

But you have to make sure you are runing this on an event like click of a button or ready or document, like on the jsfiddle.

Also make sure that theres always a value attribute on the option tags. If not, some browsers always return empty on val().

Edit:
Now that you have clarifyed the use of the Chosen plugin, you have to call

$("#autoship_option").trigger("liszt:updated");

after changing the value for it to update the intereface.

ALTER TABLE {TABLE NAME}
ALTER COLUMN {COLUMN NAME} SET DEFAULT '{DEFAULT VALUES}'

example :

ALTER TABLE RESULT
ALTER COLUMN STATUS SET DEFAULT 'FAIL'

You got this Error because you tried to convert column DataType from String to int which is

leagal if and only if

you dont have row in that table with string content inside that column

so just make sure your previously inserted Rows is compatible with the new changes

A control that is missing from the original set of WPF controls, but much used, is the NumericUpDown control. It is a neat way to get users to select a number from a fixed range, in a small area. A slider could be used, but for compact forms with little horizontal real-estate, the NumericUpDown is essential.

Solution A (via WindowsFormsHost)

You can use the Windows Forms NumericUpDown control in WPF by hosting it in a WindowsFormsHost. Pay attention that you have to include a reference to System.Windows.Forms.dll assembly.

<Window x:Class="WpfApplication61.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms" 
        Title="MainWindow" Height="350" Width="525">
    <StackPanel>    
        <WindowsFormsHost>
            <wf:NumericUpDown/>
        </WindowsFormsHost>
...

Solution B (custom)

There are several commercial and codeplex versions around, but both involve installing 3rd party dlls and overheads to your project. Far simpler to build your own, and a aimple way to do that is with the ScrollBar.

A vertical ScrollBar with no Thumb (just the repeater buttons) is in fact just what we want. It inherits rom RangeBase, so it has all the properties we need, like Min, Max, and SmallChange (set to 1, to restrict it to Integer values)

So we change the ScrollBar ControlTemplate. First we remove the Thumb and Horizontal trigger actions. Then we group the remains into a grid and add a TextBlock for the number:

<Grid Margin="2">
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition />
    </Grid.ColumnDefinitions>
    <TextBlock VerticalAlignment="Center" FontSize="20" MinWidth="25" Text="{Binding Value, RelativeSource={RelativeSource TemplatedParent}}"/>
    <Grid Grid.Column="1" x:Name="GridRoot" Width="{DynamicResource {x:Static SystemParameters.VerticalScrollBarWidthKey}}" Background="{TemplateBinding Background}">
        <Grid.RowDefinitions>
            <RowDefinition MaxHeight="18"/>
            <RowDefinition Height="0.00001*"/>
            <RowDefinition MaxHeight="18"/>
        </Grid.RowDefinitions>
        <RepeatButton x:Name="DecreaseRepeat" Command="ScrollBar.LineDownCommand" Focusable="False">
            <Grid>
                <Path x:Name="DecreaseArrow" Stroke="{TemplateBinding Foreground}" StrokeThickness="1" Data="M 0 4 L 8 4 L 4 0 Z"/>
            </Grid>
        </RepeatButton>
        <RepeatButton Grid.Row="2" x:Name="IncreaseRepeat" Command="ScrollBar.LineUpCommand" Focusable="False">
            <Grid>
                <Path x:Name="IncreaseArrow" Stroke="{TemplateBinding Foreground}" StrokeThickness="1" Data="M 0 0 L 4 4 L 8 0 Z"/>
            </Grid>
        </RepeatButton>
    </Grid>
</Grid>

This is the problem

double a[] = null;

Since a is null, NullPointerException will arise every time you use it until you initialize it. So this:

a[i] = var;

will fail.

A possible solution would be initialize it when declaring it:

double a[] = new double[PUT_A_LENGTH_HERE]; //seems like this constant should be 7

IMO more important than solving this exception, is the fact that you should learn to read the stacktrace and understand what it says, so you could detect the problems and solve it.

java.lang.NullPointerException

This exception means there's a variable with null value being used. How to solve? Just make sure the variable is not null before being used.

at twoten.TwoTenB.(TwoTenB.java:29)

This line has two parts:

• First, shows the class and method where the error was thrown. In this case, it was at <init> method in class TwoTenB declared in package twoten. When you encounter an error message with SomeClassName.<init>, means the error was thrown while creating a new instance of the class e.g. executing the constructor (in this case that seems to be the problem).
• Secondly, shows the file and line number location where the error is thrown, which is between parenthesis. This way is easier to spot where the error arose. So you have to look into file TwoTenB.java, line number 29. This seems to be a[i] = var;.

From this line, other lines will be similar to tell you where the error arose. So when reading this:

at javapractice.JavaPractice.main(JavaPractice.java:32)

It means that you were trying to instantiate a TwoTenB object reference inside the main method of your class JavaPractice declared in javapractice package.

If it has something to do control updates on cached pages here I have a nice method how to do this.

• add some javascript to the page that always get the versionnumber of the page as a string (ajax) at loading. for example: www.yoursite.com/page/about?getVer=1&__[date]
• Compare it to the stored versionnumber (stored in cookie or localStorage) if user has visited the page once, otherwise store it directly.
• If version is not the same as local version, refresh the page using window.location.reload(true)
• You will see any changes made on the page.

This method requires at least one request even when no request is needed because it already exists in the local browser cache. But the overhead is less comparing to using no cache at all (to be sure the page will show the right updated content). This requires just a few bytes for each page request instead of all content for each page.

IMPORTANT: The version info request must be implemented on your server otherwise it will return the whole page.

Example of version string returned by www.yoursite.com/page/about?getVer=1&__[date]: skg2pl-v8kqb

To give you an example in code, here is a part of my library (I don't think you can use it but maybe it gives you some idea how to do it):

o.gCheckDocVersion = function() // Because of the hard caching method, check document for changes with ajax 
{
  var sUrl = o.getQuerylessUrl(window.location.href),
      sDocVer = o.gGetData( sUrl, false );

  o.ajaxRequest({ url:sUrl+'?getVer=1&'+o.uniqueId(), cache:0, dataType:'text' }, 
                function(sVer)
                {
                   if( typeof sVer == 'string' && sVer.length )
                   {
                     var bReload = (( typeof sDocVer == 'string' ) && sDocVer != sVer );
                     if( bReload || !sDocVer )
                      { 
                        o.gSetData( sUrl, sVer ); 
                        sDocVer = o.gGetData( sUrl, false );
                        if( bReload && ( typeof sDocVer != 'string' || sDocVer != sVer ))
                         { bReload = false; }
                      }
                     if( bReload )
                      {  // Hard refresh page contents
                        window.location.reload(true); }
                   }
                }, false, false );
};

If you are using version independent resources like javascript or css files, add versionnumbers (implemented with a url rewrite and not with a query because they mostly won't be cached). For example: www.yoursite.com/ver-01/about.js

For me, this method is working great, maybe it can help you too.

many ways to change date format

I updated Mr. ganaraj answer to show stop and resume functionality and added angular js filter to format countdown timer

it is here on jsFiddle

controller code

'use strict';
var myApp = angular.module('myApp', []);
myApp.controller('AlbumCtrl', function($scope,$timeout) {
    $scope.counter = 0;
    $scope.stopped = false;
    $scope.buttonText='Stop';
    $scope.onTimeout = function(){
        $scope.counter++;
        mytimeout = $timeout($scope.onTimeout,1000);
    }
    var mytimeout = $timeout($scope.onTimeout,1000);
    $scope.takeAction = function(){
        if(!$scope.stopped){
            $timeout.cancel(mytimeout);
            $scope.buttonText='Resume';
        }
        else
        {
            mytimeout = $timeout($scope.onTimeout,1000);
            $scope.buttonText='Stop';
        }
            $scope.stopped=!$scope.stopped;
    }   
});

filter-code adapted from RobG from stackoverflow

myApp.filter('formatTimer', function() {
  return function(input)
    {
        function z(n) {return (n<10? '0' : '') + n;}
        var seconds = input % 60;
        var minutes = Math.floor(input / 60);
        var hours = Math.floor(minutes / 60);
        return (z(hours) +':'+z(minutes)+':'+z(seconds));
    };
});

execute this

EXEC sp_MSforeachtable 'PRINT ''ALTER TABLE ? NOCHECK CONSTRAINT ALL'''
EXEC sp_MSforeachtable 'print ''DELETE FROM ?'''
EXEC sp_MSforeachtable 'print ''ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all'''

After copy the printed result and paste it on Query field and Execute it. It will truncate all tables.

}

Final answer was a combination of two of the above (I've upvoted both to show my appreciation!):

select case 
   when exists (
      SELECT 1 
      FROM Sys.columns c 
      WHERE c.[object_id] = OBJECT_ID('dbo.Tags') 
         AND c.name = 'ModifiedByUserId'
   ) 
   then 1 
   else 0 
end

Based on the correct answer, but taking into account ASCII control characters as well, the solution that worked for me is this:

SELECT * FROM `table` WHERE NOT `field` REGEXP  "[\\x00-\\xFF]|^$";

It does the same thing: searches for violations of the ASCII range in a column, but lets you search for control characters too, since it uses hexadecimal notation for code points. Since there is no comparison or conversion (unlike @Ollie's answer), this should be significantly faster, too. (Especially if MySQL does early-termination on the regex query, which it definitely should.)

It also avoids returning fields that are zero-length. If you want a slightly-longer version that might perform better, you can use this instead:

SELECT * FROM `table` WHERE `field` <> "" AND NOT `field` REGEXP  "[\\x00-\\xFF]";

It does a separate check for length to avoid zero-length results, without considering them for a regex pass. Depending on the number of zero-length entries you have, this could be significantly faster.

Note that if your default character set is something bizarre where 0x00-0xFF don't map to the same values as ASCII (is there such a character set in existence anywhere?), this would return a false positive. Otherwise, enjoy!

Similar to @joran's answer. Reshape the df so that the prices for each product are in different columns:

xx <- reshape(df, idvar=c("skew","version","color"),
              v.names="price", timevar="product", direction="wide")

xx will have columns price.p1, ... price.p4, so:

ggp <- ggplot(xx,aes(x=price.p1, y=price.p3, color=factor(skew))) +
       geom_point(shape=19, size=5)
ggp + facet_grid(color~version)

gives the result from your image.

codaddict has provided the right answer. As for what you've tried, I'll explain why they don't make the cut:

• [0-9]{1,45} is almost there, however it matches a 1-to-45-digit string even if it occurs within another longer string containing other characters. Hence you need ^ and $ to restrict it to an exact match.

• ^[0-9]{45}*$ matches an exactly-45-digit string, repeated 0 or any number of times (*). That means the length of the string can only be 0 or a multiple of 45 (90, 135, 180...).

In my case the solution was:

Permissions on the config file should be 600. chmod 600 config

As mentioned in the comments above by generalopinion

No need to touch the config file contents.

At its simplest:

#include <iostream>
using namespace std;

class A {
   public:
     A( int x ) : n( x ){}
     void print() { cout << n << endl; }
   private:
     int n;
};

void func( A p ) {
   p.print();
}

int main () {
   A a;
   func ( a );
}

Of course, you should probably be using references to pass the object, but I suspect you haven't got to them yet.

perhaps I'm a dodo!

show databases; worked for me.

The simplest way to get an input box is with the Read-Host cmdlet and -AsSecureString parameter.

$us = Read-Host 'Enter Your User Name:' -AsSecureString
$pw = Read-Host 'Enter Your Password:' -AsSecureString

This is especially useful if you are gathering login info like my example above. If you prefer to keep the variables obfuscated as SecureString objects you can convert the variables on the fly like this:

[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))
[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pw))

If the info does not need to be secure at all you can convert it to plain text:

$user = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))

Read-Host and -AsSecureString appear to have been included in all PowerShell versions (1-6) but I do not have PowerShell 1 or 2 to ensure the commands work identically. https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/read-host?view=powershell-3.0

LDF holds the transaction log. If you set your backups correctly - it will be small. It it grows - you have a very common problem of setting database recovery mode to FULL and then forgetting to backup the transaction log (LDF file). Let me explain how to fix it.

1. If your business can afford to lose a little data between backups, just set the database recovery mode to SIMPLE, then forget about LDF - it will be small. This is the recommended solution for most of the cases.
2. If you have to be able to restore to the exact point in time - use FULL recovery mode. In this case you have to take regular Transaction Log backups. The simplest way to do it is to use a tool like SqlBackupAndFTP (disclosure - I am a developer). The log file will be truncated at this time and would not grow beyond certain limits.

Some would suggest to use SHRINKFILE to trim you log. Note that this is OK only as an exception. If you do it regularly, it defeats the purpose of FULL recovery model: first you go into trouble of saving every single change in the log, then you just dump it. Set recovery mode to SIMPLE instead.

I had the exact same problem while trying to setup a Gitlab pipeline executed by a Docker runner installed on a Raspberry Pi 4

Using nload to follow bandwidth usage within Docker runner container while pipeline was cloning the repo i saw the network usage dropped down to a few bytes per seconds..

After a some deeper investigations i figured out that the Raspberry temperature was too high and the network card start to dysfunction above 50° Celsius.

Adding a fan to my Raspberry solved the issue.

The problem with using <Redirect from="/" to="searchDashboard" /> is if you have a different URL, say /indexDashboard and the user hits refresh or gets a URL sent to them, the user will be redirected to /searchDashboard anyway.

If you wan't users to be able to refresh the site or send URLs use this:

<Route exact path="/" render={() => (
    <Redirect to="/searchDashboard"/>
)}/>

Use this if searchDashboard is behind login:

<Route exact path="/" render={() => (
  loggedIn ? (
    <Redirect to="/searchDashboard"/>
  ) : (
    <Redirect to="/login"/>
  )
)}/>

You sure can. Create an HTML page with the form in it that will contain the necessary components from the login.aspx page (i.e. username, etc), and make sure they have the same IDs. For you action, make sure it's a post.

You might have to do some code on the login.aspx page in the Page_Load function to read the form (in the Request.Form object) and call the appropriate functions to log the user in, but other than that, you should have access to the form, and can do what you want with it.

Here's how to make and print a 2D Multi-Dimensional Array using the ArrayList Object.

import java.util.ArrayList;

public class TwoD_ArrayListExample {
    static public ArrayList<ArrayList<String>> gameBoard = new ArrayList<ArrayList<String>>();

    public static void main(String[] args) {
        insertObjects();
        printTable(gameBoard);
    }

    public static void insertObjects() {
        for (int rowNum = 0; rowNum != 8; rowNum++) {
            ArrayList<String> oneRow = new ArrayList<String>();
            gameBoard.add(rowNum, oneRow);

            for (int columnNum = 0; columnNum != 8; columnNum++) {
                String description= "Description of Objects: row= "+ rowNum + ", column= "+ columnNum;
                    oneRow.add(columnNum, description);
            }
        }
    }

    // The printTable method prints the table to the console
    private static void printTable(ArrayList<ArrayList<String>> table) {
        for (int row = 0; row != 8; row++) {
            for (int col = 0; col != 8; col++) {
                System.out.println("Printing:               row= "+ row+ ", column= "+ col);
                System.out.println(table.get(row).get(col).toString());
            }
        }
        System.out.println("\n");
    }
}

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

Below Python packages are to be downloaded and installed to their default locations.

1.1. Python-2.7.x.

1.2. Numpy.

1.3. Matplotlib (Matplotlib is optional, but recommended since we use it a lot in our tutorials).

Install all packages into their default locations. Python will be installed to C:/Python27/.

After installation, open Python IDLE. Enter import numpy and make sure Numpy is working fine.

Download latest OpenCV release from sourceforge site and double-click to extract it.

Goto opencv/build/python/2.7 folder.

Copy cv2.pyd to C:/Python27/lib/site-packeges.

Open Python IDLE and type following codes in Python terminal.

import cv2 print cv2.version If the results are printed out without any errors, congratulations !!! You have installed OpenCV-Python successfully.

HMSET is deprecated. You can now use HSET with a dictionary as follows:

import redis
r = redis.Redis('localhost')

key = "hashexample" 
queue_entry = { 
    "version":"1.2.3", 
    "tag":"main", 
    "status":"CREATED",  
    "timeout":"30"
    }
r.hset(key,None,None,queue_entry)

Try this query

DECLARE @PrintVarchar nvarchar(max) = (Select Sum(Amount) From Expense)
PRINT 'Varchar format =' + @PrintVarchar

DECLARE @PrintInt int = (Select Sum(Amount) From Expense)
PRINT @PrintInt

Disclaimer: I haven't tried this solution, so it might not work ;-)

You should be looking at pg_enum. If you only want to change the label of an existing ENUM, a simple UPDATE will do it.

To add a new ENUM values:

• First insert the new value into pg_enum. If the new value has to be the last, you're done.
• If not (you need to a new ENUM value in between existing ones), you'll have to update each distinct value in your table, going from the uppermost to the lowest...
• Then you'll just have to rename them in pg_enum in the opposite order.

Illustration
You have the following set of labels:

ENUM ('enum1', 'enum2', 'enum3')

and you want to obtain:

ENUM ('enum1', 'enum1b', 'enum2', 'enum3')

then:

INSERT INTO pg_enum (OID, 'newenum3');
UPDATE TABLE SET enumvalue TO 'newenum3' WHERE enumvalue='enum3';
UPDATE TABLE SET enumvalue TO 'enum3' WHERE enumvalue='enum2';

then:

UPDATE TABLE pg_enum SET name='enum1b' WHERE name='enum2' AND enumtypid=OID;

And so on...

You need pow(); function from math.h header.
syntax

#include <math.h>
double pow(double x, double y);
float powf(float x, float y);
long double powl(long double x, long double y);

Here x is base and y is exponent. result is x^y.

usage

pow(2,4);  

result is 2^4 = 16. //this is math notation only   
// In c ^ is a bitwise operator

And make sure you include math.h to avoid warning ("incompatible implicit declaration of built in function 'pow' ").

Link math library by using -lm while compiling. This is dependent on Your environment.
For example if you use Windows it's not required to do so, but it is in UNIX based systems.

1. the condition num2 < num1 should be num2 <= num1 if num2 has to be greater than num1
2. not knowing what the kb object is, I'd read a String and then trying Integer.parseInt() and if you don't catch an exception then it's a number, if you do, read a new one, maybe by setting num2 to Integer.MIN_VALUE and using the same type of logic in your example.

You can use form-inline class for each form-group :)

<form>                      
    <div class="form-group form-inline">                            
        <label for="exampleInputEmail1">Email address</label>
            <input type="email" class="form-control" id="exampleInputEmail1" placeholder="Email">
    </div>
</form>

That is not what the error message says. It says that you cannot use the = operator. Try for instance LIKE 'foo'.

On PostgreSQL (and many other RDBMS), you can do it with regular ALTER TABLE statement:

=> SELECT * FROM Test1;
 id | foo | bar 
----+-----+-----
  2 |   1 |   2

=> ALTER TABLE Test1 RENAME COLUMN foo TO baz;
ALTER TABLE

=> SELECT * FROM Test1;
 id | baz | bar 
----+-----+-----
  2 |   1 |   2

These are the correct version that you can add in your build.gradle according to the API needs.

At some point, I suppose you will add your programatically created LinearLayout to some root layout that you defined in .xml. This is just a suggestion of mine and probably one of many solutions, but it works: Simply set an ID for the programatically created layout, and add it to the root layout that you defined in .xml, and then use the set ID to add the Fragment.

It could look like this:

LinearLayout rowLayout = new LinearLayout();
rowLayout.setId(whateveryouwantasid);
// add rowLayout to the root layout somewhere here

FragmentManager fragMan = getFragmentManager();
FragmentTransaction fragTransaction = fragMan.beginTransaction();   

Fragment myFrag = new ImageFragment();
fragTransaction.add(rowLayout.getId(), myFrag , "fragment" + fragCount);
fragTransaction.commit();

Simply choose whatever Integer value you want for the ID:

rowLayout.setId(12345);

If you are using the above line of code not just once, it would probably be smart to figure out a way to create unique-IDs, in order to avoid duplicates.

UPDATE:

Here is the full code of how it should be done: (this code is tested and works) I am adding two Fragments to a LinearLayout with horizontal orientation, resulting in the Fragments being aligned next to each other. Please also be aware, that I used a fixed height and width of 200dp, so that one Fragment does not use the full screen as it would with "match_parent".

MainActivity.java:

public class MainActivity extends Activity {

    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);     

        LinearLayout fragContainer = (LinearLayout) findViewById(R.id.llFragmentContainer);

        LinearLayout ll = new LinearLayout(this);
        ll.setOrientation(LinearLayout.HORIZONTAL);

        ll.setId(12345);

        getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 1"), "someTag1").commit();
        getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 2"), "someTag2").commit();

        fragContainer.addView(ll);
    }
}

TestFragment.java:

public class TestFragment extends Fragment {

    public static TestFragment newInstance(String text) {

        TestFragment f = new TestFragment();

        Bundle b = new Bundle();
        b.putString("text", text);
        f.setArguments(b);
        return f;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View v =  inflater.inflate(R.layout.fragment, container, false);

        ((TextView) v.findViewById(R.id.tvFragText)).setText(getArguments().getString("text"));     
        return v;
    }
}

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rlMain"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="5dp"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <LinearLayout
        android:id="@+id/llFragmentContainer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignLeft="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="19dp"
        android:orientation="vertical" >
    </LinearLayout>
</RelativeLayout>

fragment.xml:

  <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="200dp"
    android:layout_height="200dp" >

    <TextView
        android:id="@+id/tvFragText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="" />

</RelativeLayout>

And this is the result of the above code: (the two Fragments are aligned next to each other)

Specifically, to install the pdf.js plugin for firefox, you do not use the app store. Instead, go to addons.mozilla.org from inside mozilla and install it from there. Also, to see if it's installed properly, go to the menu Tools:Add-ons (not the "about:plugins" url as you might think from the desktop version).

(New account, otherwise I'd put this as a comment on the answer above)

My Mac decided to restart itself randomly; causing a whole slew of errors. One of which, was mysql refusing to start up properly. I went through many SO questions/answers as well as other sites.

Ultimately what ended up resolving MY issue was this:

1) Creating the file (/usr/local/mysql/data/.local.pid

2) chmod 777 on that file

3) executing mysql.server start (mine was located in/usr/local/bin/mysql.server)

The email in the profile can be obtained using extended permission but I Guess it's not possible to get the email used to login fb. In my app i wanted to display mulitple fb accounts of a user in a list, i wanted to show the login emails of fb accounts as a unique identifier of the respective accounts but i couldn't get it off from fb, all i got was the primary email in the user profile but in my case my login email and my primary email are different.

IF EXISTS() is semantically incorrect. EXISTS condition can be used only inside a SQL statement. So you might rewrite your pl/sql block as follows:

declare
  l_exst number(1);
begin
  select case 
           when exists(select ce.s_regno 
                         from courseoffering co
                         join co_enrolment ce
                           on ce.co_id = co.co_id
                        where ce.s_regno=403 
                          and ce.coe_completionstatus = 'C' 
                          and ce.c_id = 803
                          and rownum = 1
                        )
           then 1
           else 0
         end  into l_exst
  from dual;

  if l_exst = 1 
  then
    DBMS_OUTPUT.put_line('YES YOU CAN');
  else
    DBMS_OUTPUT.put_line('YOU CANNOT'); 
  end if;
end;

Or you can simply use count function do determine the number of rows returned by the query, and rownum=1 predicate - you only need to know if a record exists:

declare
  l_exst number;
begin
   select count(*) 
     into l_exst
     from courseoffering co
          join co_enrolment ce
            on ce.co_id = co.co_id
    where ce.s_regno=403 
      and ce.coe_completionstatus = 'C' 
      and ce.c_id = 803
      and rownum = 1;

  if l_exst = 0
  then
    DBMS_OUTPUT.put_line('YOU CANNOT');
  else
    DBMS_OUTPUT.put_line('YES YOU CAN');
  end if;
end;

This is even easier :

$('html').click(function(e) {
    $('.popup-marker').popover('hide');
});

$('.popup-marker').popover({
    html: true,
    trigger: 'manual'
}).click(function(e) {
    $(this).popover('toggle');
    e.stopPropagation();
});

I completly disagree with this one, but I was forced to follow it:

"All HTML LINKS will ALWAYS be underlined."

A while back I explained why I disagree on my blog.

Note: Even Stackoverflow ONLY underlines links when you move the mouse over them.

This is my 2nd iteration of the code. Because MemoryCache is thread safe you don't need to lock on the initial read, you can just read and if the cache returns null then do the lock check to see if you need to create the string. It greatly simplifies the code.

const string CacheKey = "CacheKey";
static readonly object cacheLock = new object();
private static string GetCachedData()

EDIT: The below code is unnecessary but I wanted to leave it to show the original method. It may be useful to future visitors who are using a different collection that has thread safe reads but non-thread safe writes (almost all of classes under the System.Collections namespace is like that).

Here is how I would do it using ReaderWriterLockSlim to protect access. You need to do a kind of "Double Checked Locking" to see if anyone else created the cached item while we where waiting to to take the lock.

const string CacheKey = "CacheKey";
static readonly ReaderWriterLockSlim cacheLock = new ReaderWriterLockSlim();
static string GetCachedData()
{
    //First we do a read lock to see if it already exists, this allows multiple readers at the same time.
    cacheLock.EnterReadLock();
    try
    {
        //Returns null if the string does not exist, prevents a race condition where the cache invalidates between the contains check and the retreival.
        var cachedString = MemoryCache.Default.Get(CacheKey, null) as string;

        if (cachedString != null)
        {
            return cachedString;
        }
    }
    finally
    {
        cacheLock.ExitReadLock();
    }

    //Only one UpgradeableReadLock can exist at one time, but it can co-exist with many ReadLocks
    cacheLock.EnterUpgradeableReadLock();
    try
    {
        //We need to check again to see if the string was created while we where waiting to enter the EnterUpgradeableReadLock
        var cachedString = MemoryCache.Default.Get(CacheKey, null) as string;

        if (cachedString != null)
        {
            return cachedString;
        }

        //The entry still does not exist so we need to create it and enter the write lock
        var expensiveString = SomeHeavyAndExpensiveCalculation();
        cacheLock.EnterWriteLock(); //This will block till all the Readers flush.
        try
        {
            CacheItemPolicy cip = new CacheItemPolicy()
            {
                AbsoluteExpiration = new DateTimeOffset(DateTime.Now.AddMinutes(20))
            };
            MemoryCache.Default.Set(CacheKey, expensiveString, cip);
            return expensiveString;
        }
        finally 
        {
            cacheLock.ExitWriteLock();
        }
    }
    finally
    {
        cacheLock.ExitUpgradeableReadLock();
    }
}

    line-height: 30px;
    margin: 0 auto;
    position: relative;
    text-align: center;
    text-transform: uppercase;
    top: -80px;
    left:-30px;
    display:none;
    padding:0 20px;

}
span:after{

You can add the method below to your class for providing a default implementation of RestTemplate:

@Bean
public RestTemplate restTemplate() {
    return new RestTemplate();
}

Put [] around any field names that had spaces (as Dreden says) and save your query, close it and reopen it.

Using Access 2016, I still had the error message on new queries after I added [] around any field names... until the Query was saved.

Once the Query is saved (and visible in the Objects' List), closed and reopened, the error message disappears. This seems to be a bug from Access.

Typescript recognizes the Date interface out of the box - just like you would with a number, string, or custom type. So Just use:

myDate : Date;

select * from tableName where columnName is null

You can also try:

INSERT IGNORE
  INTO table_1 
SELECT *
  FROM table_2
     ;

which allows those rows in table_1 to supersede those in table_2 that have a matching primary key, while still inserting rows with new primary keys.

Alternatively,

REPLACE
   INTO table_1
 SELECT *
   FROM table_2
      ;

will update those rows already in table_1 with the corresponding row from table_2, while inserting rows with new primary keys.

I know this is old but this answer came up in search results. For the next guy - the proposed and accepted answer works, however the code initially submitted in the question is lower-level than it needs to be. Nobody got time for that.

//one-line post request/response...
response, err := http.PostForm(APIURL, url.Values{
    "ln": {c.ln},
    "ip": {c.ip},
    "ua": {c.ua}})

//okay, moving on...
if err != nil {
  //handle postform error
}

defer response.Body.Close()
body, err := ioutil.ReadAll(response.Body)

if err != nil {
  //handle read response error
}

fmt.Printf("%s\n", string(body))

Just adding another thing that worked for me :

react-native link

Evidently my ReactNative files were no longer there. I could figure that out by clicking on

Build Phases -> Link Binary with Libraries ->

Then right clicking a file I knew was responsible for React, and clicking Show In Finder .

But nothing opened. So assuming the library went missing, I just ran the above command which relinked everything again.

Also if you havn't, try :

rm -rf node_modules/ && npm install

using json.loads will turn your data into a python dictionary.

Dictionaries values are accessed using ['key']

resp_str = {
  "name" : "ns1:timeSeriesResponseType",
  "declaredType" : "org.cuahsi.waterml.TimeSeriesResponseType",
  "scope" : "javax.xml.bind.JAXBElement$GlobalScope",
  "value" : {
    "queryInfo" : {
      "creationTime" : 1349724919000,
      "queryURL" : "http://waterservices.usgs.gov/nwis/iv/",
      "criteria" : {
        "locationParam" : "[ALL:103232434]",
        "variableParam" : "[00060, 00065]"
      },
      "note" : [ {
        "value" : "[ALL:103232434]",
        "title" : "filter:sites"
      }, {
        "value" : "[mode=LATEST, modifiedSince=null]",
        "title" : "filter:timeRange"
      }, {
        "value" : "sdas01",
        "title" : "server"
      } ]
    }
  },
  "nil" : false,
  "globalScope" : true,
  "typeSubstituted" : false
}

would translate into a python diction

resp_dict = json.loads(resp_str)

resp_dict['name'] # "ns1:timeSeriesResponseType"

resp_dict['value']['queryInfo']['creationTime'] # 1349724919000

var someParam = xxxxxxx;

commentbtn.click(function(){

    alert(someParam );
});

If you're wanting this as a script, the following Bash script should do what you want (plus tell you when the file already exists):

#!/bin/bash
if [ -e $1 ]; then
  echo "File $1 already exists!"
else
  echo >> $1
fi

If you don't want the "already exists" message, you can use:

#!/bin/bash
if [ ! -e $1 ]; then
  echo >> $1
fi

Edit about using:

Save whichever version with a name you like, let's say "create_file" (quotes mine, you don't want them in the file name). Then, to make the file executatble, at a command prompt do:

chmod u+x create_file

Put the file in a directory in your path, then use it with:

create_file NAME_OF_NEW_FILE

The $1 is a special shell variable which takes the first argument on the command line after the program name; i.e. $1 will pick up NAME_OF_NEW_FILE in the above usage example.

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)

The difference between pointers and references is quite simple: a pointer can be null, a reference can not.

Examine your API, if it makes sense for null to be able to be returned, possibly to indicate an error, use a pointer, otherwise use a reference. If you do use a pointer, you should add checks to see if it's null (and such checks may slow down your code).

Here it looks like references are more appropriate.

Try this:

yAxis: {min: 0, max: 100}

See this jsfiddle example

This is one of the ways:

String toDate = "05/11/2010";

if (new SimpleDateFormat("MM/dd/yyyy").parse(toDate).getTime() / (1000 * 60 * 60 * 24) >= System.currentTimeMillis() / (1000 * 60 * 60 * 24)) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

A bit more easy interpretable:

String toDateAsString = "05/11/2010";
Date toDate = new SimpleDateFormat("MM/dd/yyyy").parse(toDateAsString);
long toDateAsTimestamp = toDate.getTime();
long currentTimestamp = System.currentTimeMillis();
long getRidOfTime = 1000 * 60 * 60 * 24;
long toDateAsTimestampWithoutTime = toDateAsTimestamp / getRidOfTime;
long currentTimestampWithoutTime = currentTimestamp / getRidOfTime;

if (toDateAsTimestampWithoutTime >= currentTimestampWithoutTime) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

Oh, as a bonus, the JodaTime's variant:

String toDateAsString = "05/11/2010";
DateTime toDate = DateTimeFormat.forPattern("MM/dd/yyyy").parseDateTime(toDateAsString);
DateTime now = new DateTime();

if (!toDate.toLocalDate().isBefore(now.toLocalDate())) {
    System.out.println("Display report.");
} else {
    System.out.println("Don't display report.");
}

git pull and git rebase are not interchangeable, but they are closely connected.

git pull fetches the latest changes of the current branch from a remote and applies those changes to your local copy of the branch. Generally this is done by merging, i.e. the local changes are merged into the remote changes. So git pull is similar to git fetch & git merge.

Rebasing is an alternative to merging. Instead of creating a new commit that combines the two branches, it moves the commits of one of the branches on top of the other.

You can pull using rebase instead of merge (git pull --rebase). The local changes you made will be rebased on top of the remote changes, instead of being merged with the remote changes.

Atlassian has some excellent documentation on merging vs. rebasing.

To display a phone number with (###) ###-#### format, you can create a new HtmlHelper.

Usage

@Html.DisplayForPhone(item.Phone)

HtmlHelper Extension

public static class HtmlHelperExtensions
{
    public static HtmlString DisplayForPhone(this HtmlHelper helper, string phone)
    {
        if (phone == null)
        {
            return new HtmlString(string.Empty);
        }
        string formatted = phone;
        if (phone.Length == 10)
        {
            formatted = $"({phone.Substring(0,3)}) {phone.Substring(3,3)}-{phone.Substring(6,4)}";
        }
        else if (phone.Length == 7)
        {
            formatted = $"{phone.Substring(0,3)}-{phone.Substring(3,4)}";
        }
        string s = $"<a href='tel:{phone}'>{formatted}</a>";
        return new HtmlString(s);
    }
}

Performance wise there is no difference. The only purpose of having const_iterator over iterator is to manage the accessesibility of the container on which the respective iterator runs. You can understand it more clearly with an example:

std::vector<int> integers{ 3, 4, 56, 6, 778 };

If we were to read & write the members of a container we will use iterator:

for( std::vector<int>::iterator it = integers.begin() ; it != integers.end() ; ++it )
       {*it = 4;  std::cout << *it << std::endl; }

If we were to only read the members of the container integers you might wanna use const_iterator which doesn't allow to write or modify members of container.

for( std::vector<int>::const_iterator it = integers.begin() ; it != integers.end() ; ++it )
       { cout << *it << endl; }

NOTE: if you try to modify the content using *it in second case you will get an error because its read-only.

use in ashx file

public string getIP(HttpContext c)
{
    string ips = c.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
    if (!string.IsNullOrEmpty(ips))
    {
        return ips.Split(',')[0];
    }
    return c.Request.ServerVariables["REMOTE_ADDR"];
}

Use IF().

It is a short-circuiting ternary operator.

Dim Result = IF(expression,<true return>,<false return>)

SEE ALSO:

• IIF becomes If, and a true ternary operator

• Is there a conditional ternary operator in VB.NET?

• Orcas introduces the IF operator - a new and improved IIF

You can use the TelephonyManager to do this:

TelephonyManager t = (TelephonyManager)getSystemService(TELEPHONY_SERVICE); 
String number = t.getLine1Number();

Have you used

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

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

The Function type is declared as

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

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

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

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

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

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

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

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

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

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

Or I could simply do

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

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

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

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

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

myForEach(theList, Test::displayInt);

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

theList.forEach(Test::displayInt);

About Functions as First Class Citizens

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

As has been pointed out, the objects are created base-down upon construction. When the base object is being constructed, the derived object does not exist yet, so a virtual function override cannot work.

However, this can be solved with polymorphic getters that use static polymorphism instead of virtual functions if your getters return constants, or otherwise can be expressed in a static member function, This example uses CRTP (https://en.wikipedia.org/wiki/Curiously_recurring_template_pattern).

template<typename DerivedClass>
class Base
{
public:
    inline Base() :
    foo(DerivedClass::getFoo())
    {}

    inline int fooSq() {
        return foo * foo;
    }

    const int foo;
};

class A : public Base<A>
{
public:
    inline static int getFoo() { return 1; }
};

class B : public Base<B>
{
public:
    inline static int getFoo() { return 2; }
};

class C : public Base<C>
{
public:
    inline static int getFoo() { return 3; }
};

int main()
{
    A a;
    B b;
    C c;

    std::cout << a.fooSq() << ", " << b.fooSq() << ", " << c.fooSq() << std::endl;

    return 0;
}

With the use of static polymorphism, the base class knows which class' getter to call as the information is provided at compile-time.

Starting from C# 2.0, you can use the nullable generic type Nullable, and in C# there is a shorthand notation the type followed by ?

e.g.

private void Example(int? arg1, int? arg2)
{
    if(arg1 == null)
    {
        //do something
    }
    if(arg2 == null)
    {
        //do something else
    }
}

What you are looking for is a query with WITH clause, if your dbms supports it. Then

WITH NewScores AS (
    SELECT * 
    FROM Score  
    WHERE InsertedDate >= DATEADD(mm, -3, GETDATE())
)
SELECT 
<and the rest of your query>
;

Note that there is no ; in the first half. HTH.

all u need to do that is set tJAVA_HOME and JDK_HOME environment variables paths for this go my computer properties set path with name JAVA_HOME and JDK_HOME C:\Program Files\Java\jdk1.8.0_25

None of these answers seemed simple enough - the crux of the problem is not having to rebuild:

makefile

OBJDIR=out
VPATH=$(OBJDIR)

# make will look in VPATH to see if the target needs to be rebuilt
test: moo
    touch $(OBJDIR)/$@

example use

touch moo
# creates out/test
make test
# doesn't update out/test
make test
# will now update test
touch moo
make test

You could have a pseudo dynamic array where the size is set by the user at runtime, but then is fixed after that.

int size;
cin >> size;
int dynamicArray[size];

I would use python-dpkt. Here is the documentation: http://www.commercialventvac.com/dpkt.html

This is all I know how to do though sorry.

#!/usr/local/bin/python2.7

counter=0
ipcounter=0
tcpcounter=0
udpcounter=0

filename='sampledata.pcap'

for ts, pkt in dpkt.pcap.Reader(open(filename,'r')):

    counter+=1
    eth=dpkt.ethernet.Ethernet(pkt) 
    if eth.type!=dpkt.ethernet.ETH_TYPE_IP:
       continue

    ip=eth.data
    ipcounter+=1

    if ip.p==dpkt.ip.IP_PROTO_TCP: 
       tcpcounter+=1

    if ip.p==dpkt.ip.IP_PROTO_UDP:
       udpcounter+=1

print "Total number of packets in the pcap file: ", counter
print "Total number of ip packets: ", ipcounter
print "Total number of tcp packets: ", tcpcounter
print "Total number of udp packets: ", udpcounter

You can add this to your JavaScript file to allow your arrays to be "cleared":

Array.prototype.clear = function() {
    this.splice(0, this.length);
};

Then you can use it like this:

var list = [1, 2, 3];
list.clear();

Or if you want to be sure you don't destroy something:

if (!Array.prototype.clear) {
    Array.prototype.clear = function() {
       this.splice(0, this.length);
    };
}

Lots of people think you shouldn't modify native objects (like Array), and I'm inclined to agree. Please use caution in deciding how to handle this.

I'm pretty sure all of the examples above only reload the iframe with its original src, not its current URL.

$('#frameId').attr('src', function () { return $(this).contents().get(0).location.href });

That should reload using the current url.

The immutable way to replace the element in the list using ES6 spread operators and .slice method.

const arr = ['fir', 'next', 'third'], item = 'next'

const nextArr = [
  ...arr.slice(0, arr.indexOf(item)), 
  'second',
  ...arr.slice(arr.indexOf(item) + 1)
]

Verify that works

console.log(arr)     // [ 'fir', 'next', 'third' ]
console.log(nextArr) // ['fir', 'second', 'third']

In response to the OP, there are two problems with your code: you need to set jsonp='callback', and adding in a callback function in a variable like you did does not seem to work.

Update: when I wrote this the Twitter API was just open, but they changed it and it now requires authentication. I changed the second example to a working (2014Q1) example, but now using github.

This does not work any more - as an exercise, see if you can replace it with the Github API:

$('document').ready(function() {
    var pm_url = 'http://twitter.com/status';
    pm_url += '/user_timeline/stephenfry.json';
    pm_url += '?count=10&callback=photos';
    $.ajax({
        url: pm_url,
        dataType: 'jsonp',
        jsonpCallback: 'photos',
        jsonp: 'callback',
    });
});
function photos (data) {
    alert(data);
    console.log(data);
};

although alert()ing an array like that does not really work well... The "Net" tab in Firebug will show you the JSON properly. Another handy trick is doing

alert(JSON.stringify(data));

You can also use the jQuery.getJSON method. Here's a complete html example that gets a list of "gists" from github. This way it creates a randomly named callback function for you, that's the final "callback=?" in the url.

<!DOCTYPE html>
<html lang="en">
    <head>
        <title>JQuery (cross-domain) JSONP Twitter example</title>
        <script type="text/javascript"src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
        <script>
            $(document).ready(function(){
                $.getJSON('https://api.github.com/gists?callback=?', function(response){
                    $.each(response.data, function(i, gist){
                        $('#gists').append('<li>' + gist.user.login + " (<a href='" + gist.html_url + "'>" + 
                            (gist.description == "" ? "undescribed" : gist.description) + '</a>)</li>');
                    });
                });
            });
        </script>
    </head>
    <body>
        <ul id="gists"></ul>
    </body>
</html>

These are the default settings I have for /etc/network/interfaces (including WiFi settings) for my Raspberry Pi 1:

auto lo

iface lo inet loopback
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp

If you really need True or False, just use bool

>>> bool(re.search("hi", "abcdefghijkl"))
True
>>> bool(re.search("hi", "abcdefgijkl"))
False

As other answers have pointed out, if you are just using it as a condition for an if or while, you can use it directly without wrapping in bool()

Pointers generally have a fixed size, for ex. on a 32-bit executable they're usually 32-bit. There are some exceptions, like on old 16-bit windows when you had to distinguish between 32-bit pointers and 16-bit... It's usually pretty safe to assume they're going to be uniform within a given executable on modern desktop OS's.

Edit: Even so, I would strongly caution against making this assumption in your code. If you're going to write something that absolutely has to have a pointers of a certain size, you'd better check it!

Function pointers are a different story -- see Jens' answer for more info.

swift 5 version:

By using default inbuilt color:

1. button.setTitleColor(UIColor.green, for: .normal)

OR

You can use your custom color by using RGB method:

2. button.setTitleColor(UIColor(displayP3Red: 0.0/255.0, green: 180.0/255.0, blue: 2.0/255.0, alpha: 1.0), for: .normal)

You can use the MSXML Base64 encoding functionality as described at www.nonhostile.com/howto-encode-decode-base64-vb6.asp:

Function EncodeBase64(text As String) As String
  Dim arrData() As Byte
  arrData = StrConv(text, vbFromUnicode)      

  Dim objXML As MSXML2.DOMDocument
  Dim objNode As MSXML2.IXMLDOMElement

  Set objXML = New MSXML2.DOMDocument 
  Set objNode = objXML.createElement("b64")

  objNode.dataType = "bin.base64"
  objNode.nodeTypedValue = arrData
  EncodeBase64 = objNode.Text 

  Set objNode = Nothing
  Set objXML = Nothing
End Function

Well, you can't quite do it that way. PAGE.SIGN_CREATE will never return 1; it will return PAGE.SIGN_CREATE. That's the point of enumerated types.

However, if you're willing to add a few keystrokes, you can add fields to your enums, like this:

    public enum PAGE{
        SIGN_CREATE(0),
        SIGN_CREATE_BONUS(1),
        HOME_SCREEN(2),
        REGISTER_SCREEN(3);

        private final int value;

        PAGE(final int newValue) {
            value = newValue;
        }

        public int getValue() { return value; }
    }

And then you call PAGE.SIGN_CREATE.getValue() to get 0.

from jquery api

Added to jQuery in version 1.4, the .delay() method allows us to delay the execution of functions that follow it in the queue. It can be used with the standard effects queue or with a custom queue. Only subsequent events in a queue are delayed; for example this will not delay the no-arguments forms of .show() or .hide() which do not use the effects queue.

m2e is only included in the Java developer version of Eclipse, as you can see on this page ("Maven" topic): http://www.eclipse.org/downloads/compare.php

However, an easy way to get m2e is through the Eclipse Marketplace:

Go to Help -> Eclipse Marketplace and look for m2e. Click "Maven Integration for Eclipse", then on Install (or drag and drop the install link to your running Eclipse workspace if you opened the marketplace in a browser), et voila!

Direct browser access: http://marketplace.eclipse.org/content/maven-integration-eclipse

You can use this api https://code.google.com/p/google-gson/
It's simple and very useful,

Here's how to use the https://code.google.com/p/google-gson/ Api to resolve your problem

public class Test {
  public static void main(String... strings) throws FileNotFoundException  {
    Reader reader = new FileReader(new File("<fullPath>/json.js"));
    JsonElement elem = new JsonParser().parse(reader);
    Gson gson  = new GsonBuilder().create();
   TestObject o = gson.fromJson(elem, TestObject.class);
   System.out.println(o);
  }


}

class TestObject{
  public String fName;
  public String lName;
  public String toString() {
    return fName +" "+lName;
  }
}

json.js file content :

{"fName":"Mohamed",
"lName":"Ali"
}

Option 3 is your best bet, but not all DB engines have a "bit" type. If you don't have a bit, then TinyINT would be your best bet.

Simple program to understand difference between continue and break

When continue is used

    public static void main(String[] args) {
    System.out.println("HelloWorld");
    for (int i = 0; i < 5; i++){
        System.out.println("Start For loop i = " + i);
        if(i==2){
            System.out.println("Inside if Statement for i = "+i);
           continue;
        }
        System.out.println("End For loop i = " + i);
    }
    System.out.println("Completely out of For loop");
}


OutPut:
HelloWorld
Start For loop i = 0
End For loop i = 0
Start For loop i = 1
End For loop i = 1
Start For loop i = 2
Inside if Statement for i = 2
Start For loop i = 3
End For loop i = 3
Start For loop i = 4
End For loop i = 4
Completely out of For loop

When break is used

public static void main(String[] args) {
    System.out.println("HelloWorld");
    for (int i = 0; i < 5; i++){
        System.out.println("Start For loop i = " + i);
        if(i==2){
            System.out.println("Inside if Statement for i = "+i);
           break;
        }
        System.out.println("End For loop i = " + i);
    }
    System.out.println("Completely out of For loop");
}

Output:
HelloWorld
Start For loop i = 0
End For loop i = 0
Start For loop i = 1
End For loop i = 1
Start For loop i = 2
Inside if Statement for i = 2
Completely out of For loop

The suggestion from @Dawood is good if that works for you.

If you need more fine-tuning than that, one option is to use padding on the text elements, here's an example: http://jsfiddle.net/panchroma/FtBwe/

CSS

p, h2 {
    padding-left:10px;
}

Okay this will work 100% for sure.

First you will need to setup listener if keyboard is show or hide. If keyboard is showing then probably user is typing, otherwise done typing.

final View activityRootView = findViewById(android.R.id.content);
        activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {

                    Rect r = new Rect();
                    //r will be populated with the coordinates of your view that area still visible.
                    activityRootView.getWindowVisibleDisplayFrame(r);

                    int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
                    if (heightDiff > 100) { // if more than 100 pixels, its probably a keyboard...

                        isTyping = true;
                    } else {
//to make sure this will call only once when keyboard is hide.
                        if(isTyping){
                            isTyping = false;
                        }
                    }
            }
        });

Be sure to fully qualify your sheets with which workbook they are referencing!

 mainWB.Sheets.Add(After:=mainWB.Sheets(mainWB.Sheets.Count)).Name = new_sheet_name

To display each content, I use:

mylist = ['foo', 'bar']
indexval = 0
for i in range(len(mylist)):     
    print(mylist[indexval])
    indexval += 1

Example of using in a function:

def showAll(listname, startat):
   indexval = startat
   try:
      for i in range(len(mylist)):
         print(mylist[indexval])
         indexval = indexval + 1
   except IndexError:
      print('That index value you gave is out of range.')

Hope I helped.

If you're using Angular/jQuery then this might help...

<img ng-src="{{item.url}}" altSrc="{{item.alt_url}}" onerror="this.src = $(this).attr('altSrc')">

Explanation

Assuming that item has a property url that might be null, when it is then the image will show up as broken. That triggers execution of onerror attribute expression, as described above. You need to override the src attribute as described above, but you will need jQuery to access your altSrc. Couldn't get it to work with vanilla JavaScript.

Might seem a little hacky but saved the day on my project.

For those of you landing here but searching how to break out of a loop that contains an include statement use return instead of break or continue.

<?php

for ($i=0; $i < 100; $i++) { 
    if (i%2 == 0) {
        include(do_this_for_even.php);
    }
    else {
        include(do_this_for_odd.php);
    }
}

?>

If you want to break when being inside do_this_for_even.php you need to use return. Using break or continue will return this error: Cannot break/continue 1 level. I found more details here

Chain arbitrary commands using & like this:

command1 & command2 & command3 & ...

Thus, in your particular case, put this line in a batch file on your desktop:

START cmd.exe /k "cd C:\activiti-5.9\setup & ant demo.start"

You can also use && to chain commands, albeit this will perform error checking and the execution chain will break if one of the commands fails. The behaviour is detailed here.

Edit: Intrigued by @James K's comment "You CAN chain the commands, but they will have no effect", I tested some more and to my surprise discovered, that the program I was starting in my original test - firefox.exe - while not existing in a directory in the PATH environment variable, is actually executable anywhere on my system (which really made me wonder - see bottom of answer for explanation). So in fact executing...

START cmd.exe /k "cd C:\progra~1\mozill~1 && firefox"

...didn't prove the solution was working. So I chose another program (nLite) after making sure that it was not executable anywhere on my system:

START cmd.exe /k "cd C:\progra~1\nlite && nlite"

And that works just as my original answer already suggested. A Windows version is not given in the question, but I'm using Windows XP, btw.

If anybody is interested why firefox.exe, while not being in PATH, is executable anywhere on my system - and very probably on yours as well - this is due to a registry key where applications can be registered to be available everywhere. See this SU answer for details.

Simple programmatic solution for exporting a notebook to HTML without the code cells (output only): add this code in a code cell of the notebook my_notebook.ipynb you want to export:

import codecs
import nbformat
import time
from IPython.display import Javascript
from nbconvert import HTMLExporter

def save_notebook():
    display(
        Javascript("IPython.notebook.save_notebook()"),
        include=['application/javascript']
    )    

def html_export_output_only(read_file, output_file):
    exporter = HTMLExporter()
    exporter.exclude_input = True
    output_notebook = nbformat.read(read_file, as_version=nbformat.NO_CONVERT)
    output, resources = exporter.from_notebook_node(output_notebook)
    codecs.open(output_file, 'w', encoding='utf-8').write(output)


# save notebook to html
save_notebook()
time.sleep(1)
output_file = 'my_notebook_export.html'
html_export_output_only("my_notebook.ipynb", output_file)

You can use <br/><br/> or    or \ \.

declare @iMonth int
declare @sYear varchar(4)
declare @sMonth varchar(2)
set @iMonth = 0
while @iMonth > -12
begin
    set @sYear = year(DATEADD(month,@iMonth,GETDATE()))
    set @sMonth = right('0'+cast(month(DATEADD(month,@iMonth,GETDATE())) as varchar(2)),2)
    select @sYear + @sMonth
    set @iMonth = @iMonth - 1
end

PHP's config can be set in multiple places:

1. master system php.ini (usually in /etc somewhere)
2. somewhere in Apache's configuration (httpd.conf or a per-site .conf file, via php_value)
3. CLI & CGI can have a different php.ini (use the command php -i | grep memory_limit to check the CLI conf)
4. local .htaccess files (also php_value)
5. in-script (via ini_set())

In PHPinfo's output, the "Master" value is the compiled-in default value, and the "Local" value is what's actually in effect. It can be either unchanged from the default, or overridden in any of the above locations.

Also note that PHP generally has different .ini files for command-line and webserver-based operation. Checking phpinfo() from the command line will report different values than if you'd run it in a web-based script.

Just in case you use store a variable using the generic type you can easily solve this problem adding a getClassType method as follows:

public class Constant<T> {
  private T value;

  @SuppressWarnings("unchecked")
  public Class<T> getClassType () {
    return ((Class<T>) value.getClass());
  }
}

I use the provided class object later to check if it is an instance of a given class, as follows:

Constant<?> constant = ...;
if (constant.getClassType().equals(Integer.class)) {
    Constant<Integer> integerConstant = (Constant<Integer>)constant;
    Integer value = integerConstant.getValue();
    // ...
}

Android Studio:

• "File" > "Settings" and type "MissingTranslation" into the search box

Eclipse:

• Windows/Linux: In "Window" > "Preferences" > "Android" > "Lint Error Checking"
• Mac: "Eclipse" > "Preferences" > "Android" > "Lint Error Checking"

Find the MissingTranslation line, and set it to Warning as seen below:

You need to specify both source and destination, and if you want to copy directories you should look at the -r option.

So to recursively copy /home/user/whatever from remote server to your current directory:

scp -pr user@remoteserver:whatever .

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

Although standard action results FileContentResult or FileStreamResult may be used for downloading files, for reusability, creating a custom action result might be the best solution.

As an example let's create a custom action result for exporting data to Excel files on the fly for download.

ExcelResult class inherits abstract ActionResult class and overrides the ExecuteResult method.

We are using FastMember package for creating DataTable from IEnumerable object and ClosedXML package for creating Excel file from the DataTable.

public class ExcelResult<T> : ActionResult
{
    private DataTable dataTable;
    private string fileName;

    public ExcelResult(IEnumerable<T> data, string filename, string[] columns)
    {
        this.dataTable = new DataTable();
        using (var reader = ObjectReader.Create(data, columns))
        {
            dataTable.Load(reader);
        }
        this.fileName = filename;
    }

    public override void ExecuteResult(ControllerContext context)
    {
        if (context != null)
        {
            var response = context.HttpContext.Response;
            response.Clear();
            response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
            response.AddHeader("content-disposition", string.Format(@"attachment;filename=""{0}""", fileName));
            using (XLWorkbook wb = new XLWorkbook())
            {
                wb.Worksheets.Add(dataTable, "Sheet1");
                using (MemoryStream stream = new MemoryStream())
                {
                    wb.SaveAs(stream);
                    response.BinaryWrite(stream.ToArray());
                }
            }
        }
    }
}

In the Controller use the custom ExcelResult action result as follows

[HttpGet]
public async Task<ExcelResult<MyViewModel>> ExportToExcel()
{
    var model = new Models.MyDataModel();
    var items = await model.GetItems();
    string[] columns = new string[] { "Column1", "Column2", "Column3" };
    string filename = "mydata.xlsx";

The best thing to do is to use the algorithm remove_if and isspace:

remove_if(str.begin(), str.end(), isspace);

Now the algorithm itself can't change the container(only modify the values), so it actually shuffles the values around and returns a pointer to where the end now should be. So we have to call string::erase to actually modify the length of the container:

str.erase(remove_if(str.begin(), str.end(), isspace), str.end());

We should also note that remove_if will make at most one copy of the data. Here is a sample implementation:

template<typename T, typename P>
T remove_if(T beg, T end, P pred)
{
    T dest = beg;
    for (T itr = beg;itr != end; ++itr)
        if (!pred(*itr))
            *(dest++) = *itr;
    return dest;
}

Set backButtonTitle as a space on the previous screen.

// If navigation is from A -> B, set in A's `viewDidLoad`.
navigationItem.backButtonTitle = " "

You should include the repository where you want to deploy in the distribution management section of the pom.xml.

Example:

<project xmlns="http://maven.apache.org/POM/4.0.0"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
                      http://maven.apache.org/xsd/maven-4.0.0.xsd">
...   
<distributionManagement>
    <repository>
      <uniqueVersion>false</uniqueVersion>
      <id>corp1</id>
      <name>Corporate Repository</name>
      <url>scp://repo/maven2</url>
      <layout>default</layout>
    </repository>
    ...

it should be as simple as

I such cases I usually end up with a list of predicates and actions. Something along these lines:

class Mine {
    static List<Func<object, bool>> predicates;
    static List<Action<object>> actions;

    static Mine() {
        AddAction<A>(o => o.Hop());
        AddAction<B>(o => o.Skip());
    }

    static void AddAction<T>(Action<T> action) {
        predicates.Add(o => o is T);
        actions.Add(o => action((T)o);
    }

    static void RunAction(object o) {
        for (int i=0; o < predicates.Count; i++) {
            if (predicates[i](o)) {
                actions[i](o);
                break;
            }
        }
    }

    void Foo(object o) {
        RunAction(o);
    }
}

Are you using HTML5? If so, check whether you have any <input type="hidden"> in your form with the property required. Remove that required property. Internet Explorer won't take this property, so it works but Chrome will.

So far, nobody has answered the actual question.

Someone can figure what is happening ?

The problem here is that while the value of your $JAVA_HOME is correct, you defined it in the wrong place.

• When you open a terminal and launch a Bash session, it will read the ~/.bash_profile file. Thus, when you enter echo $JAVA_HOME, it will return the value that has been set there.
• When you launch IntelliJ directly, it will not read ~/.bash_profile … why should it? So to IntelliJ, this variable is not set.

There are two possible solutions to this:

• Launch IntelliJ from a Bash session: open a terminal and run "/Applications/IntelliJ IDEA.app/Contents/MacOS/idea". The idea process will inherit any environment variables of Bash that have been exported. (Since you did export JAVA_HOME=…, it works!), or, the sophisticated way:

• Set global environment variables that apply to all programs, not only Bash sessions. This is more complicated than you might think, and is explained here and here, for example. What you should do is run

  /bin/launchctl setenv JAVA_HOME $(/usr/libexec/java_home)
  

  However, this gets reset after a reboot. To make sure this gets run on every boot, execute

  cat << EOF > ~/Library/LaunchAgents/setenv.JAVA_HOME.plist
  <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
      "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
      <key>Label</key>
      <string>setenv.JAVA_HOME</string>
      <key>ProgramArguments</key>
      <array>
        <string>/bin/launchctl</string>
        <string>setenv</string>
        <string>JAVA_HOME</string>
        <string>$(/usr/libexec/java_home)</string>
      </array>
      <key>RunAtLoad</key>
      <true/>
      <key>ServiceIPC</key>
      <false/>
    </dict>
  </plist>
  EOF
  

  Note that this also affects the Terminal process, so there is no need to put anything in your ~/.bash_profile.

I just removed custom php ini, which I don't use at all. The problem gone, site is working fine.

string foo = yourDateTime.ToUniversalTime()
                         .ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fff'Z'");

You can use this extension as an alternative if you're dealing with RGB value.

extension UIColor {
    static func rgb(red: CGFloat, green: CGFloat, blue: CGFloat) -> UIColor {
        return UIColor(red: red/255, green: green/255, blue: blue/255, alpha: 1)
      }
    }

You can get Current timestamp in Android by trying below code

time.setText(String.valueOf(System.currentTimeMillis()));

and timeStamp to time format

SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
String dateString = formatter.format(new Date(Long.parseLong(time.getText().toString())));
time.setText(dateString);

Add the following to your ~/.gitconfig file

[alias]
  cat = "!git show \"$1:$2\" #"

And then try this

git cat BRANCHNAME FILEPATH

Personally I prefer separate parameters without a colon. Why? This choice mirrors the parameters of the checkout command, which I tend to use rather frequently and I find it thus much easier to remember than the bizarro colon-separated parameter of the show command.

From FormData documention:

XMLHttpRequest Level 2 adds support for the new FormData interface. FormData objects provide a way to easily construct a set of key/value pairs representing form fields and their values, which can then be easily sent using the XMLHttpRequest send() method.

With an XMLHttpRequest you can set the custom headers and then do the POST.

I hope the below example will provide more clarity.

package main

type EmployeeManager struct{
    category            string
    city                string
    calculateSalary     func() int64
}


func NewEmployeeManager() (*EmployeeManager,error){

    return &EmployeeManager{
        category : "MANAGEMENT",
        city : "NY",
        calculateSalary: func() int64 {
            var calculatedSalary int64
            // some formula
            return calculatedSalary
        },
    },nil
}

func (self *EmployeeManager) emWithSalaryCalculation(){
    self.calculateSalary = func() int64 {
        var calculatedSalary int64
        // some new formula
        return calculatedSalary
    }
}

func updateEmployeeInfo(em EmployeeManager){
    // Some code
}

func processEmployee(){
    updateEmployeeInfo(struct {
        category        string
        city            string
        calculateSalary func() int64
    }{category: "", city: "", calculateSalary: func() int64 {
        var calculatedSalary int64
        // some new formula
        return calculatedSalary
    }})
}

In my case I only wanted the image to behave responsively at mobile scale so I created a css style .myimgrsfix that only kicks in at mobile scale

.myimgrsfix {
    @media(max-width:767px){
        width:100%;
    }
}

and applied that to the image <img class='img-responsive myimgrsfix' src='whatever.gif'>

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

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

In this variable myVarDate contains the output of command.

I've always used it on the command line and not as a library, but HTMLDOC gives me excellent results, and it handles at least some CSS (I couldn't easily see how much).

Here's a sample command line

htmldoc --webpage -t pdf --size letter --fontsize 10pt index.html > index.pdf

You need to install the provisioning profile (drag and drop it into iTunes). Then drag and drop the .ipa. Ensure you device is set to sync apps, and try again.

You can use following script to get the path without trailing "\"

for %%i in ("%~dp0.") do SET "mypath=%%~fi"

To get both functions working for a clickable image that will respond to both short and long clicks, I tried the following that seems to work perfectly:

    image = (ImageView) findViewById(R.id.imageViewCompass);
    image.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            shortclick();
        }
     });

    image.setOnLongClickListener(new View.OnLongClickListener() {
    public boolean onLongClick(View v) {
        longclick();
        return true;
    }
});

//Then the functions that are called:

 public void shortclick()
{
 Toast.makeText(this, "Why did you do that? That hurts!!!", Toast.LENGTH_LONG).show();

}

 public void longclick()
{
 Toast.makeText(this, "Why did you do that? That REALLY hurts!!!", Toast.LENGTH_LONG).show();

}

It seems that the easy way of declaring the item in XML as clickable and then defining a function to call on the click only applies to short clicks - you must have a listener to differentiate between short and long clicks.

This is a problem with your remote. When you do git push origin master, origin is the remote and master is the branch you're pushing.

When you do this:

git remote

I bet the list does not include origin. To re-add the origin remote:

git remote add origin [email protected]:your_github_username/your_github_app.git

Or, if it exists but is formatted incorrectly:

git remote rm origin
git remote add origin [email protected]:your_github_username/your_github_app.git

I have a large app that was having problems uploading to the AppStore using the archive method you will find in XCode 4. The activity indicator kept spinning for hours whether I was trying to validate or distribute, so I created a support ticket to Apple. During that process, I found out you could right click on the .app in your Products folder inside the Project Navigator of XCode, and compress the app to submit using the Application Loader 2.5.1. (aka the old method). Only the Debug - iphoneos folder is accessible this way (for now) and once Apple responded, this is what they had to say:

I'm glad to hear that Application Loader has provided you a viable workaround. Discussing this situation internally, we're not sure that submitting the Debug build will pose too much of a problem (so long as it was signed with the App Store distribution profile, as you mentioned it was). The app will likely be slower as the debug switches are turned on and optimizations are turned off for the Debug configuration, though it will still run. App Review will ultimately determine whether or not that's ok, as I'm not sure that's something they check for. You could try reaching out directly to App Review to confirm this, if you wish. However, since App Loader is working for you, I do recommend rebuilding the app with your Release configuration and resubmitting to play it safe. To find your Release build in Xcode 4.x, control-click on the Application Archive on the Archives tab in the organizer, and choose "Show in Finder." Then, control-click on the .xcarchive file in Finder and choose "Show Package Contents." The release built .app file should be located within the /Products/Applications folder.

This was very helpful information for developers who are having problems with the archive method, and my app is now uploading successfully without any concern that it won't run to the best of it's ability.

used !important in CSS property

<div style="color: red;">
    Hello World, How Can I Change The Color To Blue?
</div>

div {
        color: blue !important;
    }

for just background color

Tabbarcontroller.tabBar.barTintColor=[UIColor redcolour];

or this in App Delegate

[[UITabBar appearance] setBackgroundColor:[UIColor blackColor]];

for changing color of unselect icons of tabbar

For iOS 10:

// this code need to be placed on home page of tabbar    
for(UITabBarItem *item in self.tabBarController.tabBar.items) {
    item.image = [item.image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
}

Above iOS 10:

// this need to be in appdelegate didFinishLaunchingWithOptions
[[UITabBar appearance] setUnselectedItemTintColor:[UIColor blackColor]];

    checker = True

[Edit]

For more information: http://docs.python.org/library/functions.html#bool

Your code works too, since 1 is converted to True when necessary. Actually Python didn't have a boolean type for a long time (as in old C), and some programmers still use integers instead of booleans.

I think there's a more elegant way to solve the problem: send the stdout/stderr to syslog with an identifier and instruct your syslog manager to split its output by program name.

Use the following properties in your systemd service unit file:

StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=<your program identifier> # without any quote

Then, assuming your distribution is using rsyslog to manage syslogs, create a file in /etc/rsyslog.d/<new_file>.conf with the following content:

if $programname == '<your program identifier>' then /path/to/log/file.log
& stop

Now make the log file writable by syslog:

# ls -alth /var/log/syslog 
-rw-r----- 1 syslog adm 439K Mar  5 19:35 /var/log/syslog
# chown syslog:adm /path/to/log/file.log

Restart rsyslog (sudo systemctl restart rsyslog) and enjoy! Your program stdout/stderr will still be available through journalctl (sudo journalctl -u <your program identifier>) but they will also be available in your file of choice.

Lists are allowed. A list is a set of numbers (or ranges) separated by commas. Examples: "1,2,5,9", "0-4,8-12".

So in this case it would be:

Variable number of arguments

It is possible to pass a variable number of arguments to a method. However, there are some restrictions:

• The variable number of parameters must all be the same type
• They are treated as an array within the method
• They must be the last parameter of the method

To understand these restrictions, consider the method, in the following code snippet, used to return the largest integer in a list of integers:

private static int largest(int... numbers) {
     int currentLargest = numbers[0];
     for (int number : numbers) {
        if (number > currentLargest) {
            currentLargest = number;
        }
     }
     return currentLargest;
}

Use the >> operator to append text to a file.

They are the same.

Both mean that when coming in to the load balancer, the request will be directed to the server that served the first request (and has the session).

A function returns one value, but it can "output" any number of values. A sample code:

Function Test (ByVal Input1 As Integer, ByVal Input2 As Integer, _
ByRef Output1 As Integer, ByRef Output2 As Integer) As Integer

  Output1 = Input1 + Input2
  Output2 = Input1 - Input2
  Test = Output1 + Output2

End Function

Sub Test2()

  Dim Ret As Integer, Input1 As Integer, Input2 As Integer, _
  Output1 As integer, Output2 As Integer
  Input1 = 1
  Input2 = 2
  Ret = Test(Input1, Input2, Output1, Output2)
  Sheet1.Range("A1") = Ret     ' 2
  Sheet1.Range("A2") = Output1 ' 3
  Sheet1.Range("A3") = Output2 '-1

End Sub

Test it by:

[2] pwd

The <p> tag is a paragraph, and as such, it is a block element (as is, for instance, h1 and div), whereas span is an inline element (as, for instance, b and a)

Block elements by default create some whitespace above and below themselves, and nothing can be aligned next to them, unless you set a float attribute to them.

Inline elements deal with spans of text inside a paragraph. They typically have no margins, and as such, you cannot, for instance, set a width to it.

You can reset your branch to the state it was in just before the merge if you find the commit it was on then.

One way is to use git reflog, it will list all the HEADs you've had. I find that git reflog --relative-date is very useful as it shows how long ago each change happened.

Once you find that commit just do a git reset --hard <commit id> and your branch will be as it was before.

If you have SourceTree, you can look up the <commit id> there if git reflog is too overwhelming.

Try this one, this function allows alphanumeric and spaces:

function alpha(e) {
    var k;
    document.all ? k = e.keyCode : k = e.which;
    return ((k > 64 && k < 91) || (k > 96 && k < 123) || k == 8 || k == 32 || (k >= 48 && k <= 57));
}

in your html:

<input type="text" name="name"  onkeypress="return alpha(event)"/>

In addition to @chanafdo answer, you can use route name

when working with laravel blade

<a href="{{route('login')}}">login here</a> with parameter in route name

when go to url like URI: profile/{id} <a href="{{route('profile', ['id' => 1])}}">login here</a>

without blade

<a href="<?php echo route('login')?>">login here</a>

with parameter in route name

when go to url like URI: profile/{id} <a href="<?php echo route('profile', ['id' => 1])?>">login here</a>

As of laravel 5.2 you can use @php @endphp to create as <?php ?> in laravel blade. Using blade your personal opinion but I suggest to use it. Learn it. It has many wonderful features as template inheritance, Components & Slots,subviews etc...
