I like to use git diff --no-index dir1/ dir2/, because it can show the differences in color (if you have that option set in your git config) and because it shows all of the differences in a long paged output using "less".

'^(part1|part2|part1,part2)$'

does it work?

Be aware, IBOutletCollection should be @property (strong, nonatomic).

It's been a significant percentage of our business migrating people from Heroku to AWS. There are advantages to both, but it's gets messy on Heroku after a while... once you need a certain level of complexity no longer easy to maintain with Heroku's limitations.

That said, there are increasingly options to have the ease of Heroku and the flexibility of AWS by being on AWS with great frameworks/tools.

if you have only one xml in your table, you can convert it in 2 steps:

CREATE TABLE Batches( 
   BatchID int,
   RawXml xml 
)

declare @xml xml=(select top 1 RawXml from @Batches)

SELECT  --b.BatchID,
        x.XmlCol.value('(ReportHeader/OrganizationReportReferenceIdentifier)[1]','VARCHAR(100)') AS OrganizationReportReferenceIdentifier,
        x.XmlCol.value('(ReportHeader/OrganizationNumber)[1]','VARCHAR(100)') AS OrganizationNumber
FROM    @xml.nodes('/CasinoDisbursementReportXmlFile/CasinoDisbursementReport') x(XmlCol)

If anyone is having this issue outside of a merge/conflict/action, then it could be the git lock file for your project causing the issue.

git reset
     fatal: Unable to create '/PATH_TO_PROJECT/.git/index.lock': File exists.
rm -f /PATH_TO_PROJECT/.git/index.lock
git reset
git stash pop

It leaves blank pages so that a new part or chapter start on the right-hand side. You can fix this with the "openany" option for the document class. ;)

When you are creating the router, you can specify the linkExactActiveClass as a property to set the class that will be used for the active router link.

const routes = [
  { path: '/foo', component: Foo },
  { path: '/bar', component: Bar }
]

const router = new VueRouter({
  routes,
  linkActiveClass: "active", // active class for non-exact links.
  linkExactActiveClass: "active" // active class for *exact* links.
})

This is documented here.

From a Windows Server OS execute the following command for a dump of the entire Active Director:

csvde -f test.csv

This command is very broad and will give you more than necessary information. To constrain the records to only user records, you would instead want:

csvde -f test.csv -r objectClass=user 

You can further restrict the command to give you only the fields you need relevant to the search requested such as:

csvde -f test.csv -r objectClass=user -l DN, sAMAccountName, department, memberOf

If you have an Exchange server and each user associated with a live person has a mailbox (as opposed to generic accounts for kiosk / lab workstations) you can use mailNickname in place of sAMAccountName.

Since this is tagged C# 4. With the open sourece framework ImpromptuIntereface it will use the dlr to call the constructor it is significantly faster than Activator when your constructor has arguments, and negligibly slower when it doesn't. However the main advantage is that it will handle constructors with C# 4.0 optional parameters correctly, something that Activator won't do.

protected T GetObject(params object[] args)
{
    return (T)Impromptu.InvokeConstructor(typeof(T), args);
}

Create bitmap from file path:

File sd = Environment.getExternalStorageDirectory();
File image = new File(sd+filePath, imageName);
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
Bitmap bitmap = BitmapFactory.decodeFile(image.getAbsolutePath(),bmOptions);
bitmap = Bitmap.createScaledBitmap(bitmap,parent.getWidth(),parent.getHeight(),true);
imageView.setImageBitmap(bitmap);

If you want to scale the bitmap to the parent's height and width then use Bitmap.createScaledBitmap function.

I think you are giving the wrong file path. :) Hope this helps.

.NET Framework 3.5 has got ranges:

Enumerable.Range from MSDN

you can use it with "contains" and the IF statement, since like someone said the SWITCH statement uses the "==" operator.

Here an example:

int c = 2;
if(Enumerable.Range(0,10).Contains(c))
    DoThing();
else if(Enumerable.Range(11,20).Contains(c))
    DoAnotherThing();

But I think we can have more fun: since you won't need the return values and this action doesn't take parameters, you can easily use actions!

public static void MySwitchWithEnumerable(int switchcase, int startNumber, int endNumber, Action action)
{
    if(Enumerable.Range(startNumber, endNumber).Contains(switchcase))
        action();
}

The old example with this new method:

MySwitchWithEnumerable(c, 0, 10, DoThing);
MySwitchWithEnumerable(c, 10, 20, DoAnotherThing);

Since you are passing actions, not values, you should omit the parenthesis, it's very important. If you need function with arguments, just change the type of Action to Action<ParameterType>. If you need return values, use Func<ParameterType, ReturnType>.

In C# 3.0 there is no easy Partial Application to encapsulate the fact the the case parameter is the same, but you create a little helper method (a bit verbose, tho).

public static void MySwitchWithEnumerable(int startNumber, int endNumber, Action action){ 
    MySwitchWithEnumerable(3, startNumber, endNumber, action); 
}

Here an example of how new functional imported statement are IMHO more powerful and elegant than the old imperative one.

FYI for those that are trying to create a package installer for a bundle or plugin, it's easy:

pkgbuild --component "Color Lists.colorPicker" --install-location ~/Library/ColorPickers ColorLists.pkg

// Two-dimensional GetLength example.
int[,] two = new int[5, 10];
Console.WriteLine(two.GetLength(0)); // Writes 5
Console.WriteLine(two.GetLength(1)); // Writes 10

If your entity class isn't in the same package as your main class, you can use @EntityScan annotation in the main class, specifying the Entity you want to save or package too. Like your model package.

About:

spring.jpa.hibernate.ddl-auto = create

You can use the option update. It won't erase any data, and will create tables in the same way.

Use parents() instead of parent():

$("a").click(function(event) {
  event.preventDefault();
  $(this).parents('.li').remove();
});

This solution worked for me. And I found it easier. https://jameshfisher.com/2017/08/30/how-do-i-make-a-full-width-iframe/

Well, you can hide it, by removing the entire system menu:

private const int WS_SYSMENU = 0x80000;
protected override CreateParams CreateParams
{
    get
    {
        CreateParams cp = base.CreateParams;
        cp.Style &= ~WS_SYSMENU;
        return cp;
    }
}

Of course, doing so removes the minimize and maximize buttons.

If you keep the system menu but remove the close item then the close button remains but is disabled.

The final alternative is to paint the non-client area yourself. That's pretty hard to get right.

The amount of hacks you would need to go through to completely hide the fact your site is built by Meteor.js is absolutely ridiculous. You would have to strip essentially all core functionality and just serve straight up html, completely defeating the purpose of using the framework anyway.

That being said, I suggest looking at buildwith.com

You enter a url, and it reveals a ton of information about a site. If you only need to "fool" engines like this, there may be simple solutions.

A jar file is a zip archive. You can extract it using 7zip (a great simple tool to open archives). You can also change its extension to zip and use whatever to unzip the file.

Now you have your class file. There is no easy way to edit class file, because class files are binaries (you won't find source code in there. maybe some strings, but not java code). To edit your class file you can use a tool like classeditor.

You have all the strings your class is using hard-coded in the class file. So if the only thing you would like to change is some strings you can do it without using classeditor.

import pygame
pygame.init()
pygame.display.set_mode()
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit(); #sys.exit() if sys is imported
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_0:
                print("Hey, you pressed the key, '0'!")
            if event.key == pygame.K_1:
                print("Doing whatever")

In note that K_0 and K_1 aren't the only keys, to see all of them, see pygame documentation, otherwise, hit tab after typing in

pygame.

(note the . after pygame) into an idle program. Note that the K must be capital. Also note that if you don't give pygame a display size (pass no args), then it will auto-use the size of the computer screen/monitor. Happy coding!

What about SYSDATE() ?

<?php
  $db = mysql_connect('localhost','user','pass');
  mysql_select_db('test_db');

  $stmt = "INSERT INTO `test` (`first`,`last`,`whenadded`) VALUES ".
          "('{$first}','{$last}','SYSDATE())";
  $rslt = mysql_query($stmt);
?>

Look at Difference between NOW(), SYSDATE() & CURRENT_DATE() in MySQL for more info about NOW() and SYSDATE().

Regarding git fetch -p, its behavior changed in Git 1.9, and only Git 2.9.x/2.10 reflects that.

See commit 9e70233 (13 Jun 2016) by Jeff King (peff).
^{(Merged by Junio C Hamano -- gitster -- in commit 1c22105, 06 Jul 2016)}

fetch: document that pruning happens before fetching

This was changed in 10a6cc8 (fetch --prune: Run prune before fetching, 2014-01-02), but it seems that nobody in that discussion realized we were advertising the "after" explicitly.

So the documentation now states:

Before fetching, remove any remote-tracking references that no longer exist on the remote

That is because:

When we have a remote-tracking branch named "frotz/nitfol" from a previous fetch, and the upstream now has a branch named "frotz", fetch would fail to remove "frotz/nitfol" with a "git fetch --prune" from the upstream. git would inform the user to use "git remote prune" to fix the problem.

Change the way "fetch --prune" works by moving the pruning operation before the fetching operation. This way, instead of warning the user of a conflict, it automatically fixes it.

Change the variable into a property and add a breakpoint in the set method. Example:

private bool m_Var = false;
protected bool var
{
    get { 
        return m_var;
    }

    set { 
        m_var = value;
    }
}

print(inspect.stack()[0].function) seems to work too (Python 3.5).

You could also use vbCrLf which corresponds to Chr(13) & Chr(10).

press f5 for running queries instead of f9. It will give you all the results in one go...

I tried some of the suggestions here and I would like to present mine (which is a bit different) - I hope it will help someone. I wanted to show the popup on first click and hide it on second click (of course with updating the data each time). I used an extra variable visable to know whether the popover is visable or not. Here is my code: HTML:

<button type="button" id="votingTableButton" class="btn btn-info btn-xs" data-container="body" data-toggle="popover" data-placement="left" >Last Votes</button>

Javascript:

$('#votingTableButton').data("visible",false);

$('#votingTableButton').click(function() {  
if ($('#votingTableButton').data("visible")) {
    $('#votingTableButton').popover("hide");
    $('#votingTableButton').data("visible",false);          
}
else {
    $.get('votingTable.json', function(data) {
        var content = generateTableContent(data);
        $('#votingTableButton').popover('destroy');
        $('#votingTableButton').popover({title: 'Last Votes', 
                                content: content, 
                                trigger: 'manual',
                                html:true});
        $('#votingTableButton').popover("show");
        $('#votingTableButton').data("visible",true);   
    });
}   
});

Cheers!

Here is a solution to the literal question of how to print a message to the browser's error console, not the debugger console. (There might be good reasons to bypass the debugger.)

As I noted in comments about the suggestion to throw an error to get a message in the error console, one problem is that this will interrupt the thread of execution. If you don't want to interrupt the thread, you can throw the error in a separate thread, one created using setTimeout. Hence my solution (which turns out to be an elaboration of the one by Ivo Danihelka):

var startTime = (new Date()).getTime();
function logError(msg)
{
  var milliseconds = (new Date()).getTime() - startTime;
  window.setTimeout(function () {
    throw( new Error(milliseconds + ': ' + msg, "") );
  });
}
logError('testing');

I include the time in milliseconds since the start time because the timeout could skew the order in which you might expect to see the messages.

The second argument to the Error method is for the filename, which is an empty string here to prevent output of the useless filename and line number. It is possible to get the caller function but not in a simple browser independent way.

It would be nice if we could display the message with a warning or message icon instead of the error icon, but I can't find a way to do that.

Another problem with using throw is that it could be caught and thrown away by an enclosing try-catch, and putting the throw in a separate thread avoids that obstacle as well. However, there is yet another way the error could be caught, which is if the window.onerror handler is replaced with one that does something different. Can't help you there.

Insertion Sort

After i iterations the first i elements are ordered.

In each iteration the next element is bubbled through the sorted section until it reaches the right spot:

sorted  | unsorted
1 3 5 8 | 4 6 7 9 2
1 3 4 5 8 | 6 7 9 2

The 4 is bubbled into the sorted section

Pseudocode:

for i in 1 to n
    for j in i downto 2
        if array[j - 1] > array[j]
            swap(array[j - 1], array[j])
        else
            break

Bubble Sort

After i iterations the last i elements are the biggest, and ordered.

In each iteration, sift through the unsorted section to find the maximum.

unsorted  | biggest
3 1 5 4 2 | 6 7 8 9
1 3 4 2 | 5 6 7 8 9

The 5 is bubbled out of the unsorted section

Pseudocode:

for i in 1 to n
    for j in 1 to n - i
         if array[j] > array[j + 1]
             swap(array[j], array[j + 1])

Note that typical implementations terminate early if no swaps are made during one of the iterations of the outer loop (since that means the array is sorted).

Difference

In insertion sort elements are bubbled into the sorted section, while in bubble sort the maximums are bubbled out of the unsorted section.

Here is an example using a cURL call.. This is better than the file_get_contents() function. Of course, use base64_encode()

$url = "http://example.com";

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);
?>

<img src="data:image/png;base64,<?php echo base64_encode($output);?>">  

You have not used float:left command for your text.

Though this question already has sufficient answers, I thought somebody would want to know why this flag works in this peculiar manner, This is what I found in Android documentation

The currently running instance of activity B in the above example will either receive the new intent you are starting here in its onNewIntent() method, or be itself finished and restarted with the new intent.

If it has declared its launch mode to be "multiple" (the default) and you have not set FLAG_ACTIVITY_SINGLE_TOP in the same intent, then it will be finished and re-created; for all other launch modes or if FLAG_ACTIVITY_SINGLE_TOP is set then this Intent will be delivered to the current instance's onNewIntent().

So, Either,
1. Change the launchMode of the Activity A to something else from standard (ie. singleTask or something). Then your flag FLAG_ACTIVITY_CLEAR_TOP will not restart your Activity A.

or,

2. Use Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP as your flag. Then it will work the way you desire.

Just use following:

FOR JAVA USERS

In case you are using activity --> AlertDialog.Builder builder = new AlertDialog.Builder(this);

OR

AlertDialog.Builder builder = new AlertDialog.Builder(your_activity.this);

In case you are using fragment --> AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

FOR KOTLIN USERS

In case you are using activity --> val builder = AlertDialog.Builder(this)

OR

val builder = AlertDialog.Builder(this@your_activity.this)

In case you are using fragment --> val builder = AlertDialog.Builder(activity!!)

Not sure if I get you right, but the simplest way would be something like:

<c:if test="${languageBean.locale == 'en'">
  <f:selectItems value="#{customerBean.selectableCommands_limited_en}" />
</c:if>

Just a quick copy and paste from an app of mine...

Asking that question points out that you may be interested in error handling strategies. How and where to handle errors is a pervasive architectural question. There are several ways to do this.

My favorite: allow the Exceptions to ripple through - catch them at the 'main loop' or in some other function with the appropriate responsibilities. Checking for error conditions and handling them appropriately can be seen as a specialized responsibility.

Sure do have a look at Aspect Oriented Programming, too - they have neat ways to insert if( o == null ) handleNull() into your bytecode.

It turns out that you don’t have to run the command again as Administrator, and doing so won’t fix the problem.

Try:

1. npm cache clean first.

2. If that doesn’t fix things, take a look in %APPDATA%\npm-cache, or if you’re using PowerShell, $env:APPDATA\npm-cache.

After cleaning the cache, you may still be left with remnants. Manually remove everything in that directory, and try again. This has always fixed things for me.

As @Crazzymatt was mentioning, as of the npm@5 version and up, we need to use npm cache verify instead of npm cache clean. Or else you will get an error as preceding.

npm ERR! As of npm@5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use 'npm cache verify' instead.

(Source: MSDN Blog post)

Short answer: I guess these annotations are only useful for your IDE to warn you of potentially null pointer errors.

As said in the "Clean Code" book, you should check your public method's parameters and also avoid checking invariants.

Another good tip is never returning null values, but using Null Object Pattern instead.

Go to..

File > Settings > Appearance & Behavior > System Settings > HTTP Proxy Enable following option Auto-detect proxy settings

and press checkConnection button for test

Bootstrap's CSS for the .container class looks like that:

.container {
    padding-right: 15px;
    padding-left: 15px;
    margin-right: auto;
    margin-left: auto;
}
@media (min-width: 768px) {
    .container {
        width: 750px;
    }
}
@media (min-width: 992px) {
    .container {
        width: 970px;
    }
}
@media (min-width: 1200px) {
    .container {
        width: 1170px;
    }
}

So this means we can safely rely on jQuery('.container').css('width') to detect breakpoints without the drawbacks of relying on jQuery(window).width().

We can write a function like this:

function detectBreakpoint() {
    // Let's ensure we have at least 1 container in our pages.
    if (jQuery('.container').length == 0) {
        jQuery('body').append('<div class="container"></div>');
    }

    var cssWidth = jQuery('.container').css('width');

    if (cssWidth === '1170px') return 'lg';
    else if (cssWidth === '970px') return 'md';
    else if (cssWidth === '750px') return 'sm';

    return 'xs';
}

And then test it like

jQuery(document).ready(function() {
    jQuery(window).resize(function() {
        jQuery('p').html('current breakpoint is: ' + detectBreakpoint());
    });

    detectBreakpoint();
});

$image_folder = APPPATH . "../images/owner_profile/" . $_POST ['mob_no'] [0] . $na;
            if (isset ( $_FILES ['image'] ) && $_FILES ['image'] ['error'] == 0) {
                list ( $a, $b ) = explode ( '.', $_FILES ['image'] ['name'] );
                $b = end ( explode ( '.', $_FILES ['image'] ['name'] ) );
                $up = move_uploaded_file ( $_FILES ['image'] ['tmp_name'], $image_folder . "." . $b );
                $path = ($_POST ['mob_no'] [0] . $na . "." . $b);

If it returns "this.state is undefined" - bind timer function:

constructor(props){
    super(props);
    this.state = {currentCount: 10}
    this.timer = this.timer.bind(this)
}

I know it's late in the day but might help someone else!

body,html {
  height: 100%;
}

.contentarea {

 /* 
  * replace 160px with the sum of height of all other divs 
  * inc padding, margins etc 
  */
  min-height: calc(100% - 160px); 
}

Here's your bulletproof solution:

<table width="100%" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td width="33%" align="center" valign="top" style="font-family:Arial, Helvetica, sans-serif; font-size:2px; color:#ffffff;">.</td>
    <td width="35%" align="center" valign="top">
      CONTENT GOES HERE
    </td>
    <td width="33%" align="center" valign="top" style="font-family:Arial, Helvetica, sans-serif; font-size:2px; color:#ffffff;">.</td>
  </tr>
</table>

Just Try it out, Looks a bit messy, but It works Even with the new Firefox Update for Yahoo mail. (doesn't center the email because replace the main table by a div)

No, there isn't.

I'm pretty sure there is no way to intercept a click on the refresh button from JS, and even if there was, JS can be turned off.

You should probably step back from your X (preventing refreshing) and find a different solution to Y (whatever that might be).

text.Trim() is to be used

string txt = "                   i am a string                                    ";
txt = txt.Trim();

replot

This is another way to get multiple plots at once:

plot file1.data
replot file2.data

Alternative solution that won't append a spurious CR-LF:

$original_file ='C:\Users\abc\Desktop\File\abc.txt'
$text = [IO.File]::ReadAllText($original_file) -replace "`r`n", "`n"
[IO.File]::WriteAllText($original_file, $text)

If you want to run angular app ported from another machine without ng command then edit package.json as follows

"scripts": {
    "ng": "ng",
    "start": "node node_modules/.bin/ng serve",
    "build": "node node_modules/.bin/ng build",
    "test": "node node_modules/.bin/ng test",
    "lint": "node node_modules/.bin/ng lint",
    "e2e": "node node_modules/.bin/ng e2e"
  }

Finally run usual npm start command to start build server.

There is actually a truly invisible character: U+FEFF. This character is called the Byte Order Mark and is related to the Unicode 8 system. It is a really confusing concept that can be explained HERE The Byte Order Mark or BOM for short is an invisible character that doesn't take up any space. You can copy the character bellow between the > and <.

Here is the character:

> <

How to catch this character in action:

• Copy the character between the > and <,
• Write a line of text, then randomly put your caret in the line of text
• Paste the character in the line.
• Go to the beginning of the line and press and hold the right arrow key.

You will notice that when your caret gets to the place you pasted the character, it will briefly stop for around half a second. This is becuase the caret is passing over the invisible character. Even though you can't see it doesn't mean it isn't there. The caret still sees that there is a character in that area that you pasted the BOM and will pass through it. Since the BOM is invisble, the caret will look like it has paused for a brief moment. You can past the BOM multiple times in an area and redo the steps above to really show the affect. Good luck!

EDIT: Sadly, Stackoverflow doesn't like the character. Here is an example from w3.org: https://www.w3.org/International/questions/examples/phpbomtest.php

You can also use values.makeIterator() to iterate over dict values, like this:

for sb in sbItems.values.makeIterator(){
  // do something with your sb item..
  print(sb)
}

You can also do the iteration like this, in a more swifty style:

sbItems.values.makeIterator().forEach{
  // $0 is your dict value..
  print($0) 
}

sbItems is dict of type [String : NSManagedObject]

You better use Twitter Bootstrap which contains all of this nice stuff inside. Particularly here is exactly what you want.

In addition, you can use different themes built for Twitter Bootstrap from this website

Copy all order entries of home folder .iml file into your /src/main/main.iml file. This will solve the problem.

A great search engine for special characters that I recenetly found: amp-what?

You can even search by object name, like "arrow", "chess", etc...

So, your goal is to search and replace?
According to the Official Visual Studio's keyboard shotcuts pdf, you can press Ctrl + H on Windows and Linux, or ??F on Mac to enable search and replace tool:

If you mean to disable the code, you just have to put <h1> in search, and replace to ####.

But if you want to use this regex instead, you may enable it in the icon: and use the regex: <h1>(.+?)<\/h1> and replace to: #### $1.

And as @tpartee suggested, here is some more information about Visual Studio's engine if you would like to learn more:

• Find and Replace Window (documentation)
• Quick Replace, Find and Replace Window (documentation)
• What flavor of Regex does Visual Studio Code use?

How about:

find . -name '*.h' -o -name '*.cpp' -exec grep "CP_Image" {} \; -print

try
{
    $tableAresults = $dbHandler->doSomethingWithTableA();
    if(!tableAresults)
    {
        throw new Exception('Problem with tableAresults');
    }
    $tableBresults = $dbHandler->doSomethingElseWithTableB();
    if(!tableBresults) 
    {
        throw new Exception('Problem with tableBresults');
    }
} catch (Exception $e)

Change the Android version to use while rendering layouts in the IDE.

Go to your xml layout file -> Design -> change Android API version from Automatically Pick Best to a value in between your minimum and target sdk versions.

I found the easiest way was to:

1. Convert the samples column into a DataFrame
2. Joining with the original df
3. Melting

Shown here:

    df.samples.apply(lambda x: pd.Series(x)).join(df).\
melt(['subject','trial_num'],[0,1,2],var_name='sample')

        subject  trial_num sample  value
    0         1          1      0  -0.24
    1         1          2      0   0.14
    2         1          3      0  -0.67
    3         2          1      0  -1.52
    4         2          2      0  -0.00
    5         2          3      0  -1.73
    6         1          1      1  -0.70
    7         1          2      1  -0.70
    8         1          3      1  -0.29
    9         2          1      1  -0.70
    10        2          2      1  -0.72
    11        2          3      1   1.30
    12        1          1      2  -0.55
    13        1          2      2   0.10
    14        1          3      2  -0.44
    15        2          1      2   0.13
    16        2          2      2  -1.44
    17        2          3      2   0.73

It's worth noting that this may have only worked because each trial has the same number of samples (3). Something more clever may be necessary for trials of different sample sizes.

this may help for auto adjusting the image height having image 100% width

image: { width: "100%", resizeMode: "center" "contain", height: undefined, aspectRatio: 1, }

int is a primitive, null is not a value that it can take on. You could change the method return type to return java.lang.Integer and then you can return null, and existing code that returns int will get autoboxed.

Nulls are assigned only to reference types, it means the reference doesn't point to anything. Primitives are not reference types, they are values, so they are never set to null.

Using the object wrapper java.lang.Integer as the return value means you are passing back an Object and the object reference can be null.

I recommend dynamically adding the elements, and if using jQuery or other JavaScript library, it is quite simple:

• http://api.jquery.com/appendTo/
• http://api.jquery.com/prependTo/
• http://api.jquery.com/html/

also look at prepend and append. Otherwise if you have an image tag like that, and you want to make it validate, then you might consider using a dummy image, such as a 1px transparent gif or png.

Here's a solution (and it has some quirks, but let me know if you notice them and that they're a concern):

<div>
    <div style="width:200px;float:left;display:inline-block;">
        Hello world
    </div>
    <div style="margin-left:200px;">
        Hello world
    </div>
</div>

You can choose any extension in the world if you setup Apache correctly. You could use .html to do PHP if you set up in your Apache config.

In conclusion, extension has nothing to do with the app or website itself. You can use the one you want, but normaly, use .php (to not reinvent the wheel)

But in 2019, you should use routing and forgot about extension at the end.

I recommend you using Laravel.

In answer to @KingCrunch: True, Apache not use it by default but you can easily use it if you change config. But this it not recommended since everybody know that it not really an option.

I already saw .html files that executed PHP using the html extension.

Sending an html email is not much different from sending normal emails using php. What is necessary to add is the content type along the header parameter of the php mail() function. Here is an example.

<?php
    $to = "[email protected]";
    $subject = "HTML email";
    $message = "
    <html>
    <head>
    <title>HTML email</title>
    </head>
    <body>
    <p>A table as email</p>
    <table>
    <tr>
    <th>Firstname</th>
    <th>Lastname</th>
    </tr>
    <tr>
    <td>Fname</td>
    <td>Sname</td>
    </tr>
    </table>
    </body>
    </html>
    ";
    // Always set content-type when sending HTML email
    $headers = "MIME-Version: 1.0" . "\r\n";
    $headers .= "Content-type:text/html;charset=UTF-8" . "\r\b";
    $headers .= 'From: name' . "\r\n";
    mail($to,$subject,$message,$headers);
?>

You can save the variables in the network using

saver = tf.train.Saver() 
saver.save(sess, 'path of save/fileName.ckpt')

To restore the network for reuse later or in another script, use:

saver = tf.train.Saver()
saver.restore(sess, tf.train.latest_checkpoint('path of save/')
sess.run(....) 

Important points:

1. sess must be same between first and later runs (coherent structure).
2. saver.restore needs the path of the folder of the saved files, not an individual file path.

Configure static ip for your laptop and raspberry pi. On the rapberryPI configure it as following.

pi@rpi>sudo nano /etc/network/interfaces

Then configure following as required to connect to your laptop.

iface eth0 inet static

address 192.168.1.81

netmask 255.255.255.0

broadcast 192.168.1.255

Create two partial indexes:

CREATE UNIQUE INDEX favo_3col_uni_idx ON favorites (user_id, menu_id, recipe_id)
WHERE menu_id IS NOT NULL;

CREATE UNIQUE INDEX favo_2col_uni_idx ON favorites (user_id, recipe_id)
WHERE menu_id IS NULL;

This way, there can only be one combination of (user_id, recipe_id) where menu_id IS NULL, effectively implementing the desired constraint.

Possible drawbacks: you cannot have a foreign key referencing (user_id, menu_id, recipe_id), you cannot base CLUSTER on a partial index, and queries without a matching WHERE condition cannot use the partial index. (It seems unlikely you'd want a FK reference three columns wide - use the PK column instead).

If you need a complete index, you can alternatively drop the WHERE condition from favo_3col_uni_idx and your requirements are still enforced.
The index, now comprising the whole table, overlaps with the other one and gets bigger. Depending on typical queries and the percentage of NULL values, this may or may not be useful. In extreme situations it might even help to maintain all three indexes (the two partial ones and a total on top).

Aside: I advise not to use mixed case identifiers in PostgreSQL.

Try this:

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

I recommend to use both, prop and attr because I had problems with Chrome and I solved it using both functions.

if ($(':checkbox').is(':checked')){
    $(':checkbox').prop('checked', true).attr('checked', 'checked');
}
else {
    $(':checkbox').prop('checked', false).removeAttr('checked');
}

Make sure to double the entry with an additional "www"-prefix. If you don't addresses like "www.acme.com" will not work!

You can retrieve the height of the IFRAME's content by using: contentWindow.document.body.scrollHeight

After the IFRAME is loaded, you can then change the height by doing the following:

<script type="text/javascript">
  function iframeLoaded() {
      var iFrameID = document.getElementById('idIframe');
      if(iFrameID) {
            // here you can make the height, I delete it first, then I make it again
            iFrameID.height = "";
            iFrameID.height = iFrameID.contentWindow.document.body.scrollHeight + "px";
      }   
  }
</script>   

Then, on the IFRAME tag, you hook up the handler like this:

<iframe id="idIframe" onload="iframeLoaded()" ...

I had a situation a while ago where I additionally needed to call iframeLoaded from the IFRAME itself after a form-submission occurred within. You can accomplish that by doing the following within the IFRAME's content scripts:

parent.iframeLoaded();

You're nearly there!

For a bold text, you should have this: <b> bold text</b> or <strong>bold text</strong> They have the same result.

Working example - JSfiddle

There is no difference between them.

If you don't specify a value for any of the half-dozen properties that background is a shorthand for, then it is set to its default value. none and transparent are the defaults.

One explicitly sets the background-image to none and implicitly sets the background-color to transparent. The other is the other way around.

Had a similar issue. The issue started occurring suddenly - we are having load balanced database connection URL, but in jdbc connections I was pointing to a single db directly.

Changed to load balanced db url and it worked.

If you don't need to handle raster files and PDF/PS/EPS through the same tool, don't loosen ImageMagick's security.

Instead, keep your defense in depth for your web applications intact, check that your Ghostscript has been patched for all known -dSAFER vulnerabilities and then invoke it directly.

gs -dSAFER -r300 -sDEVICE=png16m -o document-%03d.png document.pdf

• -dSAFER opts you out of the legacy-compatibility "run Postscript will full permission to interact with the outside world as a turing-complete programming language" mode.
• -r300 sets the desired DPI to 300 (the default is 72)
• -sDEVICE specifies the output format (See the Devices section of the manual for other choices.)
• -o is a shorthand for -dBATCH -dNOPAUSE -sOutputFile=
• This section of the Ghostscript manual gives some example formats for for multi-file filename output but, for the actual syntax definition, it points you at the documentation for the C printf(3) function.

If you're rendering EPS files, add -dEPSCrop so it won't pad your output to page size and use -sDEVICE=pngalpha to get transparent backgrounds.

$mail = new PHPMailer;
$mail->isSMTP(); 
$mail->isHTML(true);

Insert this code after working all html tag like

<br> <p> in $mail->Body='Hello<br> how are you ?<b>';

The default display property for a table is display:table;. The only other useful value is inline-table. All other display values are invalid for table elements.

There isn't an auto option to reset it to default, although if you're working in Javascript, you can set it to an empty string, which will do the trick.

width:auto; is valid, but isn't the default. The default width for a table is 100%, whereas width:auto; will make the element only take up as much width as it needs to.

min-width:auto; isn't allowed. If you set min-width, it must have a value, but setting it to zero is probably as good as resetting it to default.

To answer the title of your question directly because this comes up in Google first:

YES, TypeScript can export a function!

Here is a direct quote from the TS Documentation:

"Any declaration (such as a variable, function, class, type alias, or interface) can be exported by adding the export keyword."

Reference Link

it's easy to use:

frame.setResizable(false);

https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html#Cluster_Application_State_API

PUT http://{rm http address:port}/ws/v1/cluster/apps/{appid}/state

{
  "state":"KILLED"
}

CSS 3 introduces rgba colour, and you can combine it with graphics for a backwards compatible solution.

Here's one possible method.

function isMouseInBox(e) {
  var textbox = document.getElementById('textbox');

  // Box position & sizes
  var boxX = textbox.offsetLeft;
  var boxY = textbox.offsetTop;
  var boxWidth = textbox.offsetWidth;
  var boxHeight = textbox.offsetHeight;

  // Mouse position comes from the 'mousemove' event
  var mouseX = e.pageX;
  var mouseY = e.pageY;
  if(mouseX>=boxX && mouseX<=boxX+boxWidth) {
    if(mouseY>=boxY && mouseY<=boxY+boxHeight){
       // Mouse is in the box
       return true;
    }
  }
}

document.addEventListener('mousemove', function(e){
    isMouseInBox(e);
})

If you're experiencing this problem, check to make sure you don't have

methods: {
...
}

or

computed: {
...
}

declared twice

@ - Instance variable of a class
@@ - Class variable, also called as static variable in some cases

A class variable is a variable that is shared amongst all instances of a class. This means that only one variable value exists for all objects instantiated from this class. If one object instance changes the value of the variable, that new value will essentially change for all other object instances.

Another way of thinking of thinking of class variables is as global variables within the context of a single class. Class variables are declared by prefixing the variable name with two @ characters (@@). Class variables must be initialized at creation time

This method gets all your object's property names in an array, so you can get the length of that array which is equal to your object's keys' length.

Object.getOwnPropertyNames({"hi":"Hi","msg":"Message"}).length; // => 2

Laravel's Autoload is a bit different:

1) It will in fact use Composer for some stuff

2) It will call Composer with the optimize flag

3) It will 'recompile' loads of files creating the huge bootstrap/compiled.php

4) And also will find all of your Workbench packages and composer dump-autoload them, one by one.

I have the same problem, I overcame it with an ugly -- but useful -- set of GOTOs.

The reason I call the "script runner" before everything is that I want to hide the complexity and ugly approach from any developer that just wants to work with the actual script. At the same time, I can make sure that the script is run in the two (extensible to three and more) databases in the exact same way.

GOTO ScriptRunner

ScriptExecutes:

--------------------ACTUAL SCRIPT--------------------
-------- Will be executed in DB1 and in DB2 ---------
--TODO: Your script right here

------------------ACTUAL SCRIPT ENDS-----------------

GOTO ScriptReturns

ScriptRunner:
    USE DB1
    GOTO ScriptExecutes

ScriptReturns:
    IF (db_name() = 'DB1')
    BEGIN
        USE DB2
        GOTO ScriptExecutes
    END

With this approach you get to keep your variables and SQL Server does not freak out if you happen to go over a DECLARE statement twice.

You can try and check for the referer, which should be the parent site if you're an iframe

you can do that like this:

var href = document.referrer;

You are using the correct API, but is the "marker" variable visible to the entire script. I don't see this marker variable declared globally.

marks = raw_input('Enter your Obtain marks:')
outof = raw_input('Enter Out of marks:')
marks = int(marks)
outof = int(outof)
per = marks*100/outof
print 'Your Percentage is:'+str(per)

Note : raw_input() function is used to take input from console and its return string formatted value. So we need to convert into integer otherwise it give error of conversion.

You can keep it disabled as desired, and then remove the disabled attribute before the form is submitted.

$('#myForm').submit(function() {
    $('checkbox').removeAttr('disabled');
});

you must have record in table or array record in database.

example:

SELECT * FROM tabel_record
WHERE table_record.fieldName IN (SELECT fieldName FROM table_reference);

If you don't have to come back on the page with keeping form's value, you can do that :

<form method="post" th:action="@{''}" th:object="${form}">
    <input class="form-control"
           type="text"
           th:field="${client.name}"/>

It's some kind of magic :

• it will set the value = client.name
• it will send back the value in the form, as 'name' field. So you would have to change your form field, 'clientName' to 'name'

If you matter keeping you form's input values, like a back on the page with an user input mistake, then you will have to do that :

<form method="post" th:action="@{''}" th:object="${form}">
    <input class="form-control"
           type="text"
           th:name="name"
           th:value="${form.name != null} ? ${form.name} : ${client.name}"/>

That means :

• The form field name is 'name'
• The value is taken from the form if it exists, else from the client bean. Which matches the first arrival on the page with initial value, then the forms input values if there is an error.

Without having to map your client bean to your form bean. And it works because once you submitted the form, the value arn't null but "" (empty)

I think the above answer posted by Jeremy Thompson is the correct one, but I don't have enough street cred to comment. Once I updated nuget and powershellget, Install-Module was available for me.

Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force 
Install-PackageProvider -Name Powershellget -Force

What is interesting is that the version numbers returned by get-packageprovider didn't change after the update.

As AlienWebGuy said, you can use background-image. I'd suggest you use background, but it will need three more properties after the URL:

background: url("http://www.gentleface.com/i/free_toolbar_icons_16x16_black.png") 0 0 no-repeat;

Explanation: the two zeros are x and y positioning for the image; if you want to adjust where the background image displays, play around with these (you can use both positive and negative values, e.g: 1px or -1px).

No-repeat says you don't want the image to repeat across the entire background. This can also be repeat-x and repeat-y.

CSRF protection

TYPES OF CSRF USAGE

IN FORM

<form>
   @csrf
</form>

or

<input type="hidden" name="token" value="{{ form_token() }}" />

META TAG

<meta name="csrf-token" content="{{ csrf_token() }}">

AJAX

$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});

SESSION

use Illuminate\Http\Request;

Route::get('/token', function (Request $request) {
    $token = $request->session()->token();

    $token = csrf_token();

    // ...
});

MIDDLEWARE

 App\Providers\RouteServiceProvider

<?php

namespace App\Http\Middleware;

use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as Middleware;

class VerifyCsrfToken extends Middleware
{
    /**
     * The URIs that should be excluded from CSRF verification.
     *
     * @var array
     */
    protected $except = [
        'stripe/*',
        'http://example.com/foo/bar',
        'http://example.com/foo/*',
    ];
}

You can check wether an arrow key is pressed by:

$(document).keydown(function(e){
    if (e.keyCode > 36 && e.keyCode < 41) { 
       alert( "arrowkey pressed" );
       return false;
    }
});

You can use tcpkill (part of the dsniff package) to kill the connection that's on the port you need:

sudo tcpkill -9 port PORT_NUMBER

from s in db.Services
join sa in db.ServiceAssignments on s.Id equals sa.ServiceId
where sa.LocationId == 1
select s

Where db is your DbContext. Generated query will look like (sample for EF6):

SELECT [Extent1].[Id] AS [Id]
       -- other fields from Services table
FROM [dbo].[Services] AS [Extent1]
INNER JOIN [dbo].[ServiceAssignments] AS [Extent2]
    ON [Extent1].[Id] = [Extent2].[ServiceId]
WHERE [Extent2].[LocationId] = 1

The only way would be to convert your text field into an nvarchar field.

Select Cast(notes as nvarchar(4000)) + 'SomeText'
From NotesTable a

Otherwise, I suggest doing the concatenation in your application.

Another alternative would be to show a Toast/Snackbar on the first back press asking to press back again to Exit, which is a lot less intrusive than showing an AlertDialog to confirm if user wants to exit the app.

You can use the DoubleBackPress Android Library to achieve this with a few lines of code. Example GIF showing similar behaviour.

To begin with, add the dependency to your application :

dependencies {
    implementation 'com.github.kaushikthedeveloper:double-back-press:0.0.1'
}

Next, in your Activity, implement the required behaviour.

// set the Toast to be shown on FirstBackPress (ToastDisplay - builtin template)
// can be replaced by custom action (new FirstBackPressAction{...})
FirstBackPressAction firstBackPressAction = new ToastDisplay().standard(this);

// set the Action on DoubleBackPress
DoubleBackPressAction doubleBackPressAction = new DoubleBackPressAction() {
    @Override
    public void actionCall() {
        // TODO : Exit the application
        finish();
        System.exit(0);
    }
};

// setup DoubleBackPress behaviour : close the current Activity
DoubleBackPress doubleBackPress = new DoubleBackPress()
        .withDoublePressDuration(3000)     // msec - wait for second back press
        .withFirstBackPressAction(firstBackPressAction)
        .withDoubleBackPressAction(doubleBackPressAction);

Finally, set this as the behaviour on back press.

@Override
public void onBackPressed() {
    doubleBackPress.onBackPressed();
}

just put this

    <init-param>
        <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
        <param-value>true</param-value>
    </init-param>

Go for whatever is most readable and easily maintainable. Just because you can write it out in a single line doesn't mean that you should. Your existing solution is close to what I would use other than I would user iteritems to skip the value lookup, and I hate nested ifs if I can avoid them:

for key, val in d.iteritems():
    if filter_string not in key:
        continue
    # do something

However if you realllly want something to let you iterate through a filtered dict then I would not do the two step process of building the filtered dict and then iterating through it, but instead use a generator, because what is more pythonic (and awesome) than a generator?

First we create our generator, and good design dictates that we make it abstract enough to be reusable:

# The implementation of my generator may look vaguely familiar, no?
def filter_dict(d, filter_string):
    for key, val in d.iteritems():
        if filter_string not in key:
            continue
        yield key, val

And then we can use the generator to solve your problem nice and cleanly with simple, understandable code:

for key, val in filter_dict(d, some_string):
    # do something

In short: generators are awesome.

sed solution:

echo "a b c" | sed 's/ \+/\n/g'

Result:

a
b
c

Simple usage of GDB, to debug coredump files:

gdb <executable_path> <coredump_file_path>

A coredump file for a "process" gets created as a "core.pid" file.

After you get inside the GDB prompt (on execution of the above command), type:

...
(gdb) where

This will get you with the information, of the stack, where you can analayze the cause of the crash/fault. Other command, for the same purposes is:

...
(gdb) bt full

This is the same as above. By convention, it lists the whole stack information (which ultimately leads to the crash location).

Starting with a set of bytes which encode a string using UTF-8, creates a string from that data, then get some bytes encoding the string in a different encoding:

    byte[] utf8bytes = { (byte)0xc3, (byte)0xa2, 0x61, 0x62, 0x63, 0x64 };
    Charset utf8charset = Charset.forName("UTF-8");
    Charset iso88591charset = Charset.forName("ISO-8859-1");

    String string = new String ( utf8bytes, utf8charset );

    System.out.println(string);

    // "When I do a getbytes(encoding) and "
    byte[] iso88591bytes = string.getBytes(iso88591charset);

    for ( byte b : iso88591bytes )
        System.out.printf("%02x ", b);

    System.out.println();

    // "then create a new string with the bytes in ISO-8859-1 encoding"
    String string2 = new String ( iso88591bytes, iso88591charset );

    // "I get a two different chars"
    System.out.println(string2);

this outputs strings and the iso88591 bytes correctly:

âabcd 
e2 61 62 63 64 
âabcd

So your byte array wasn't paired with the correct encoding:

    String failString = new String ( utf8bytes, iso88591charset );

    System.out.println(failString);

Outputs

âabcd

(either that, or you just wrote the utf8 bytes to a file and read them elsewhere as iso88591)

I just wanted to throw in this idea that uses iteration but some other code does that iteration:

#include <string.h>

bool is_number(const std::string& s)
{
    return( strspn( s.c_str(), "-.0123456789" ) == s.size() );
}

It's not robust like it should be when checking for a decimal point or minus sign since it allows there to be more than one of each and in any location. The good thing is that it's a single line of code and doesn't require a third-party library.

Take out the '.' and '-' if positive integers are all that are allowed.

In the end I had to give the Windows Everyone group read access to that folder to get it to work properly.

I think it could be used for "retroactively forking"

If you have a Git repo, and have now decided that it should have forked another repo. Retroactively you would like it to become a fork, without disrupting the team that uses the repo by needing them to target a new repo.

But I could be wrong.

Assuming you're referring to this plugin, your code should be:

// To Store
$(function() {
    $.session.set("myVar", "value");
});


// To Read
$(function() {
    alert($.session.get("myVar"));
});

Before using a plugin, remember to read its documentation in order to learn how to use it. In this case, an usage example can be found in the README.markdown file, which is displayed on the project page.

In plain-old JavaScript you can do this:

var inputs = document.getElementsByTagName('input');

for(var i = 0; i < inputs.length; i++) {
    if(inputs[i].type.toLowerCase() == 'text') {
        alert(inputs[i].value);
    }
}

In jQuery, you would just do:

// select all inputs of type 'text' on the page
$("input:text")

// hide all text inputs which are descendants of div class="foo"
$("div.foo input:text").hide();

Install-Package System.Drawing.Common

Very late to the party but hopefully this will help someone, was in the same situation for about a hour without any of the solutions mentioned above working. (On a Windows 10 machine).

In the Settings/Preferences dialog (Ctrl+Alt+S), from the side menu select Project: | Project Interpreter.

Check which packages you currently have installed (You need SQLAlchemy and Flask-SQLAlchemy). Double click on any package name, an 'Available Packages' menu will open.

Search for the missing package(s) and click install.

The preceding answers don't insist enough on the main problem: even in very simple queries like

(SELECT t2.* FROM t1, t2 WHERE t2.id = t1.id ORDER BY t1.id) 

a temporary table can be required, and if a VARCHAR field is involved, it is converted to a CHAR field in the temporary table. So if you have in your table say 500 000 lines with a VARCHAR(65000) field, this column alone will use 6.5*5*10^9 byte. Such temp tables can't be handled in memory and are written to disk. The impact can be expected to be catastrophic.

The current v2 registry now supports deleting via DELETE /v2/<name>/manifests/<reference>

See: https://github.com/docker/distribution/blob/master/docs/spec/api.md#deleting-an-image

Working usage: https://github.com/byrnedo/docker-reg-tool

Edit: The manifest <reference> above can be retrieved from requesting to

GET /v2/<name>/manifests/<tag>

and checking the Docker-Content-Digest header in the response.

Edit 2: You may have to run your registry with the following env set:

REGISTRY_STORAGE_DELETE_ENABLED="true"

Edit3: You may have to run garbage collection to free this disk space: https://docs.docker.com/registry/garbage-collection/

List.toArray() necessarily returns an array of Object. To get an array of String, you need to use the casting syntax:

String[] strarray = strlist.toArray(new String[0]);

See the javadoc for java.util.List for more.

If you removed the make all line from your "fresh" target:

fresh :
    rm -f *.o $(EXEC)
    clear

You could simply run the command make fresh all, which will execute as make fresh; make all.

Some might consider this as a second instance of make, but it's certainly not a sub-instance of make (a make inside of a make), which is what your attempt seemed to result in.

Math.round

It worth mentioning that the build time will be increased for VS 2015 users after:

Install-Package Microsoft.Net.Compilers

Those who are using VS 2015 and have to keep this package in their projects can fix increased build time.

Edit file packages\Microsoft.Net.Compilers.1.2.2\build\Microsoft.Net.Compilers.props and clean it up. The file should look like:

<Project DefaultTargets="Build" 
         xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
</Project>

Doing so forces a project to be built as it was before adding Microsoft.Net.Compilers package

@Babasaheb Gosavi Answer is perfect if you have one occurrence of the substrings (":" and ";"). but once you have multiple occurrences, it might get little bit tricky.

The best solution I have came up with to work on multiple projects is using four methods inside an object.

• First method: is to actually get a substring from between two strings (however it will find only one result).
• Second method: will remove the (would-be) most recently found result with the substrings after and before it.
• Third method: will do the above two methods recursively on a string.
• Fourth method: will apply the third method and return the result.

Code

So enough talking, let's see the code:

var getFromBetween = {
    results:[],
    string:"",
    getFromBetween:function (sub1,sub2) {
        if(this.string.indexOf(sub1) < 0 || this.string.indexOf(sub2) < 0) return false;
        var SP = this.string.indexOf(sub1)+sub1.length;
        var string1 = this.string.substr(0,SP);
        var string2 = this.string.substr(SP);
        var TP = string1.length + string2.indexOf(sub2);
        return this.string.substring(SP,TP);
    },
    removeFromBetween:function (sub1,sub2) {
        if(this.string.indexOf(sub1) < 0 || this.string.indexOf(sub2) < 0) return false;
        var removal = sub1+this.getFromBetween(sub1,sub2)+sub2;
        this.string = this.string.replace(removal,"");
    },
    getAllResults:function (sub1,sub2) {
        // first check to see if we do have both substrings
        if(this.string.indexOf(sub1) < 0 || this.string.indexOf(sub2) < 0) return;

        // find one result
        var result = this.getFromBetween(sub1,sub2);
        // push it to the results array
        this.results.push(result);
        // remove the most recently found one from the string
        this.removeFromBetween(sub1,sub2);

        // if there's more substrings
        if(this.string.indexOf(sub1) > -1 && this.string.indexOf(sub2) > -1) {
            this.getAllResults(sub1,sub2);
        }
        else return;
    },
    get:function (string,sub1,sub2) {
        this.results = [];
        this.string = string;
        this.getAllResults(sub1,sub2);
        return this.results;
    }
};

How to use?

Example:

var str = 'this is the haystack {{{0}}} {{{1}}} {{{2}}} {{{3}}} {{{4}}} some text {{{5}}} end of haystack';
var result = getFromBetween.get(str,"{{{","}}}");
console.log(result);
// returns: [0,1,2,3,4,5]

In pthread_exit, ret is an input parameter. You are simply passing the address of a variable to the function.

In pthread_join, ret is an output parameter. You get back a value from the function. Such value can, for example, be set to NULL.

Long explanation:

In pthread_join, you get back the address passed to pthread_exit by the finished thread. If you pass just a plain pointer, it is passed by value so you can't change where it is pointing to. To be able to change the value of the pointer passed to pthread_join, it must be passed as a pointer itself, that is, a pointer to a pointer.

I am a beginner so here is a beginners answer. The if in the for loop gives i which can then be used however needed such as Numbers[i] in another vector. Most is fluff for examples sake, the for/if really says it all.

int main(){
vector<string>names{"Sara", "Harold", "Frank", "Taylor", "Sasha", "Seymore"};
string req_name;
cout<<"Enter search name: "<<'\n';
cin>>req_name;
    for(int i=0; i<=names.size()-1; ++i) {
        if(names[i]==req_name){
            cout<<"The index number for "<<req_name<<" is "<<i<<'\n';
            return 0;
        }
        else if(names[i]!=req_name && i==names.size()-1) {
            cout<<"That name is not an element in this vector"<<'\n';
        } else {
            continue;
        }
    }

You can also use numpy.subtract

It has the advantage over the difference operator, -, that you do not have to transform the sequences (list or tuples) into a numpy arrays — you save the two commands:

array1 = np.array([1.1, 2.2, 3.3])
array2 = np.array([1, 2, 3])

Example: (Python 3.5)

import numpy as np
result = np.subtract([1.1, 2.2, 3.3], [1, 2, 3])
print ('the difference =', result)

which gives you

the difference = [ 0.1  0.2  0.3]

Remember, however, that if you try to subtract sequences (lists or tuples) with the - operator you will get an error. In this case, you need the above commands to transform the sequences in numpy arrays

Wrong Code:

print([1.1, 2.2, 3.3] - [1, 2, 3])

I've simplified clone45 steps:

Open the ports as he mentioned

sudo su
sudo yum install vsftpd
echo -n "Public IP of your instance: " && read publicip
echo -e "anonymous_enable=NO\npasv_enable=YES\npasv_min_port=1024\npasv_max_port=1048\npasv_address=$publicip\nchroot_local_user=YES" >> /etc/vsftpd/vsftpd.conf
sudo /etc/init.d/vsftpd restart

Running a 32-bit OS is a mistake; you should definitely upgrade at the earliest convenience.

I don't know whether Java requires its heap to be in a single contiguous chunk, but if it does, asking for 1.8G of heap on a 32-bit box sounds like a tall order. You're assuming that there is a chunk of address space, almost half of it, free at JVM startup time.

Depending on what other libraries are loaded at the time, there may not be. Libraries can allocate memory anywhere they like, so it could fragment your address space sufficiently that 1.8G is not available in one chunk.

There is only about 3G address space max available on Linux 32-bit anyway. Libraries and the JVM itself uses some to start with.

Just a few comments:

1. Don't set PYTHONPATH if all you want is to get Python on the PATH. The PYTHONPATH environment variable tells Python where to look for modules to import. Setting it to C:\Python27\ will not accomplish anything useful, although it's probably harmless.

2. Modifying environment variables (including PATH) from the "Edit System Variables" has no effect on already running processes. This means you have to re-launch cmd.exe for the changes to work. A reboot, however, is not required.

3. When modifying the PATH, also add the Scripts subdirectory. Or, to put it in other words (and using the previous example): add ;C:\Python27;C:\Python27\Scripts. This will allow you to run scripts like easy_install, pip, virtualenv or sphinx from the command line - once you install those, that is. This is about as UNIX-y as it gets for Windows. (N.B. The Scripts subdirectory is not present after a clean install of Python, but will be created when needed.)

4. Don't put any additional Lib or DLL directory on the PATH. There's no need, and it might do harm.

5. If you have installed multiple versions of Python (which isn't all that uncommon) you might be better off not putting any of them on the PATH but instead create different shortcuts to cmd.exe for the different versions which set the PATH for each version. You might also be interested in PEP-397.

From Python version 2.6 on you can use multiple arguments to set.intersection(), like

u = set.intersection(s1, s2, s3)

If the sets are in a list, this translates to:

u = set.intersection(*setlist)

where *a_list is list expansion

Note that set.intersection is not a static method, but this uses the functional notation to apply intersection of the first set with the rest of the list. So if the argument list is empty this will fail.

To change your app font follow the following steps:

1. Inside res directory create a new directory and name it font.
2. Insert your font .ttf/.otf inside the font folder, Make sure the font name is lower case letters and underscore only.
3. Inside res -> values -> styles.xml inside <resources> -> <style> add your font <item name="android:fontFamily">@font/font_name</item>.

Now all your app text should be in the font that you add.

You can try this.

1. Create a Database onto SQL Server 2008.
2. Using Import Data feature import data from SQL Server R2 (or any higher version).
3. use "RedGate SQLCompare" to synchronize script.

If you use SQL authentication, use this:

using System.Data.SqlClient;

SqlConnection conn = new SqlConnection();
conn.ConnectionString = 
     "Data Source=.\SQLExpress;" + 
     "User Instance=true;" + 
     "User Id=UserName;" + 
     "Password=Secret;" + 
     "AttachDbFilename=|DataDirectory|Database1.mdf;"
conn.Open();

If you use Windows authentication, use this:

using System.Data.SqlClient;
SqlConnection conn = new SqlConnection();
conn.ConnectionString = 
     "Data Source=.\SQLExpress;" + 
     "User Instance=true;" + 
     "Integrated Security=true;" + 
     "AttachDbFilename=|DataDirectory|Database1.mdf;"
conn.Open();

Create a new array with a thousand true values:

var items = Enumerable.Repeat<bool>(true, 1000).ToArray();  // Or ToList(), etc.

Similarly, you can generate integer sequences:

var items = Enumerable.Range(0, 1000).ToArray();  // 0..999

While personally I would be preferring !str.isBlank(), as others already suggested (or str -> !str.isBlank() as a Predicate), a more modern and efficient version of the str.trim() approach mentioned above, would be using str.strip() - considering nulls as "whitespace":

if (str != null && str.strip().length() > 0) {...}

For example as Predicate, for use with streams, e. g. in a unit test:

@Test
public void anyNonEmptyStrippedTest() {
    String[] strings = null;
    Predicate<String> isNonEmptyStripped = str -> str != null && str.strip().length() > 0;
    assertTrue(Optional.ofNullable(strings).map(arr -> Stream.of(arr).noneMatch(isNonEmptyStripped)).orElse(true));
    strings = new String[] { null, "", " ", "\\n", "\\t", "\\r" };
    assertTrue(Optional.ofNullable(strings).map(arr -> Stream.of(arr).anyMatch(isNonEmptyStripped)).orElse(true));
    strings = new String[] { null, "", " ", "\\n", "\\t", "\\r", "test" };
}

It looks you are almost there. Try:

if(error == true){

    // Your application has indicated there's an error
    window.setTimeout(function(){

        // Move to a new location or you can do something else
        window.location.href = "https://www.google.co.in";

    }, 5000);

}

mysqli_fetch_array() returns NULL if there is no row.

In procedural style:

if ( ! $row = mysqli_fetch_array( $result ) ) {
    ... no result ...
}
else {
    ... get the first result in $row ...
}

In Object oriented style:

if ( ! $row = $result->fetch_array() ) {
    ...
}
else {
    ... get the first result in $row ...
}

Edit 2018-05-28 I have changed the example to use Java 8's Time API:

LocalDate d1 = LocalDate.parse("2018-05-26", DateTimeFormatter.ISO_LOCAL_DATE);
LocalDate d2 = LocalDate.parse("2018-05-28", DateTimeFormatter.ISO_LOCAL_DATE);
Duration diff = Duration.between(d1.atStartOfDay(), d2.atStartOfDay());
long diffDays = diff.toDays();

If no table with such name exists, DROP fails with error while DROP IF EXISTS just does nothing.

This is useful if you create/modifi your database with a script; this way you do not have to ensure manually that previous versions of the table are deleted. You just do a DROP IF EXISTS and forget about it.

Of course, your current DB engine may not support this option, it is hard to tell more about the error with the information you provide.

301 is a cacheable response per HTTP RFC and browsers will cache it depending on the HTTP caching headers you have on the response. Use FireBug or Charles to examine response headers to know the exact duration the response will be cached for.

If you would like to control the caching duration, you can use the the HTTP response headers Cache-Control and Expires to do the same. Alternatively, if you don't want to cache the 301 response at all, use the following headers.

Cache-Control: no-store, no-cache, must-revalidate
Expires: Thu, 01 Jan 1970 00:00:00 GMT

You'll want to set a "list-style" via CSS, and give it a color: value. Example:

ul.colored {list-style: color: green;}

To archive the necessary result with double constructor you need to round the BigDecimal before convert it to String e.g.

new java.math.BigDecimal(10.0001).round(new java.math.MathContext(6, java.math.RoundingMode.HALF_UP)).toString()

will print the "10.0001"

References are not objects. They don't have storage of their own, they just reference existing objects. For this reason it doesn't make sense to have arrays of references.

If you want a light-weight object that references another object then you can use a pointer. You will only be able to use a struct with a reference member as objects in arrays if you provide explicit initialization for all the reference members for all struct instances. References cannot be default initalized.

Edit: As jia3ep notes, in the standard section on declarations there is an explicit prohibition on arrays of references.

set.seed is a base function that it is able to generate (every time you want) together other functions (rnorm, runif, sample) the same random value.

From Artima's Typing: Strong vs. Weak, Static vs. Dynamic article:

strong typing prevents mixing operations between mismatched types. In order to mix types, you must use an explicit conversion

weak typing means that you can mix types without an explicit conversion

In the Pascal Costanza's paper, Dynamic vs. Static Typing — A Pattern-Based Analysis (PDF), he claims that in some cases, static typing is more error-prone than dynamic typing. Some statically typed languages force you to manually emulate dynamic typing in order to do "The Right Thing". It's discussed at Lambda the Ultimate.

Those two queries are performing OUTER JOIN. See below

Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions, which do not apply to the FROM clause OUTER JOIN syntax:

• You cannot specify the (+) operator in a query block that also contains FROM clause join syntax.

• The (+) operator can appear only in the WHERE clause or, in the context of left- correlation (when specifying the TABLE clause) in the FROM clause, and can be applied only to a column of a table or view.

• If A and B are joined by multiple join conditions, then you must use the (+) operator in all of these conditions. If you do not, then Oracle Database will return only the rows resulting from a simple join, but without a warning or error to advise you that you do not have the results of an outer join.

• The (+) operator does not produce an outer join if you specify one table in the outer query and the other table in an inner query.

• You cannot use the (+) operator to outer-join a table to itself, although self joins are valid. For example, the following statement is not valid:

  -- The following statement is not valid:
  SELECT employee_id, manager_id
     FROM employees
     WHERE employees.manager_id(+) = employees.employee_id;
  

  However, the following self join is valid:

  SELECT e1.employee_id, e1.manager_id, e2.employee_id
     FROM employees e1, employees e2
     WHERE e1.manager_id(+) = e2.employee_id
     ORDER BY e1.employee_id, e1.manager_id, e2.employee_id;
  

• The (+) operator can be applied only to a column, not to an arbitrary expression. However, an arbitrary expression can contain one or more columns marked with the (+) operator.

• A WHERE condition containing the (+) operator cannot be combined with another condition using the OR logical operator.

• A WHERE condition cannot use the IN comparison condition to compare a column marked with the (+) operator with an expression.

If the WHERE clause contains a condition that compares a column from table B with a constant, then the (+) operator must be applied to the column so that Oracle returns the rows from table A for which it has generated nulls for this column. Otherwise Oracle returns only the results of a simple join.

In a query that performs outer joins of more than two pairs of tables, a single table can be the null-generated table for only one other table. For this reason, you cannot apply the (+) operator to columns of B in the join condition for A and B and the join condition for B and C. Refer to SELECT for the syntax for an outer join.

I had the same problem "PHP Fatal error: Cannot redeclare class XYZ.php".

I have two directories like controller and model and I uploaded by mistakenly XYZ.php in both directories.(so file with the same name cause the issue).

First solution:

Find in your whole project and make sure you have only one class XYZ.php.

Second solution:

Add a namespace in your class so you can use the same class name.

You can use contains (this works with an arbitrary sequence):

df.filter($"foo".contains("bar"))

like (SQL like with SQL simple regular expression whith _ matching an arbitrary character and % matching an arbitrary sequence):

df.filter($"foo".like("bar"))

or rlike (like with Java regular expressions):

df.filter($"foo".rlike("bar"))

depending on your requirements. LIKE and RLIKE should work with SQL expressions as well.

According PEP8,I prefer to execute SQL in this way:

cur = con.cursor()
# There is no need to add single-quota to the surrounding of `%s`,
# because the MySQLdb precompile the sql according to the scheme type
# of each argument in the arguments list.
sql = "SELECT * FROM records WHERE email LIKE %s;"
args = [search, ]
cur.execute(sql, args)

In this way, you will recognize that the second argument args of execute method must be a list of arguments.

May this helps you.

If you want to push or pull your files from devices monitor now android studio offers something better then android monitor. Just take a look at right side of your studio there is an option device file explorer. Open it and you are good to go. Select your device from top dropdown and rest of everything is pretty much the same as it was in android monitor. Below is the screen Shot attached to give you the exact location and idea.

Since you are using jQuery please use it's seralize function to serialize data and then pass it into the data parameter of ajax call:

info[0] = 'hi';
info[1] = 'hello';

var data_to_send = $.serialize(info);

$.ajax({
    type: "POST",
    url: "index.php",
    data: data_to_send,
    success: function(msg){
        $('.answer').html(msg);
    }
});

No. You have 2 options:

DateTime date = DateTime.MinValue;

This works when you need to do something every X amount of time (since you will always be over MinValue) but can actually cause subtle errors (such as using some operators w/o first checking if you are not MinValue) if you are not careful.

And you can use Nullable:

DateTime? date = null;

Which is nice and avoids most issues while introducing only 1 or 2.

It really depends on what you are trying to achieve.

Date has the time part, so we only need to extract it from Date

I personally prefer the default format parameter of the Date when date and time needs to be separated instead of using the extra SimpleDateFormat

Date date = new Date()
String datePart = date.format("dd/MM/yyyy")
String timePart = date.format("HH:mm:ss")

println "datePart : " + datePart + "\ttimePart : " + timePart

COUNT(expresion) returns the count of of rows where expresion is not null. So SELECT COUNT (COL_NAME) FROM TABLE WHERE COL_NAME IS NULL will return 0, because you are only counting col_name where col_name is null, and a count of nothing but nulls is zero. COUNT(*) will return the number of rows of the query:

SELECT COUNT (*) FROM TABLE WHERE COL_NAME IS NULL

The other two queries are probably not returning any rows, since they are trying to match against strings with one blank character, and your dump query indicates that the column is actually holding nulls.

If you have rows with variable strings of space characters that you want included in the count, use:

SELECT COUNT (*) FROM TABLE WHERE trim(COL_NAME) IS NULL

trim(COL_NAME) will remove beginning and ending spaces. If the string is nothing but spaces, then the string becomes '' (empty string), which is equivalent to null in Oracle.

This is a non-standard (but not so uncommon) React pattern that doesn't use JSX, instead putting everything inline. Also, it's Coffeescript.

The 'React-way' to do this would be with the component's own state:

(c = console.log.bind console)

mock_items: [
    {
        name: 'item_a'
        uid: shortid()
    }
    {
        name: 'item_b'
        uid: shortid()
    }
    {
        name: 'item_c'
        uid: shortid()
    }
]
getInitialState: ->
    lighted_item: null
render: ->
    div null,
        ul null,
            for item, idx in @mock_items
                uid = item.uid
                li
                    key: uid
                    onClick: do (idx, uid) =>
                        (e) =>
                            # justf to illustrate these are bound in closure by the do lambda,
                            c idx
                            c uid
                            @setState
                                lighted_item: uid
                    style:
                        cursor: 'pointer'
                        background: do (uid) =>
                            c @state.lighted_item
                            c 'and uid', uid
                            if @state.lighted_item is uid then 'magenta' else 'chartreuse'
                        # background: 'chartreuse'
                    item.name

This example works -- I tested it locally. You can check out this example code exactly at my github. Originally the env was only local for my own whiteboard r&d purposes but I posted it to Github for this. It may get written over at some point but you can check out the commit from Sept 8, 2016 to see this.

More generally, if you want to see how this CS/no-JSX pattern for React works, check out some recent work here. It's possible I will have time to fully implement a POC for this app idea, the stack for which includes NodeJS, Primus, Redis, & React.

The main problem with the validated answer is you'll have to parse the output to get the informations. Here is a query allowing you to get them in a more usable manner :

SELECT cols.TABLE_NAME, cols.COLUMN_NAME, cols.ORDINAL_POSITION,
cols.COLUMN_DEFAULT, cols.IS_NULLABLE, cols.DATA_TYPE,
    cols.CHARACTER_MAXIMUM_LENGTH, cols.CHARACTER_OCTET_LENGTH,
    cols.NUMERIC_PRECISION, cols.NUMERIC_SCALE,
    cols.COLUMN_TYPE, cols.COLUMN_KEY, cols.EXTRA,
    cols.COLUMN_COMMENT, refs.REFERENCED_TABLE_NAME, refs.REFERENCED_COLUMN_NAME,
    cRefs.UPDATE_RULE, cRefs.DELETE_RULE,
    links.TABLE_NAME, links.COLUMN_NAME,
    cLinks.UPDATE_RULE, cLinks.DELETE_RULE
FROM INFORMATION_SCHEMA.`COLUMNS` as cols
LEFT JOIN INFORMATION_SCHEMA.`KEY_COLUMN_USAGE` AS refs
ON refs.TABLE_SCHEMA=cols.TABLE_SCHEMA
    AND refs.REFERENCED_TABLE_SCHEMA=cols.TABLE_SCHEMA
    AND refs.TABLE_NAME=cols.TABLE_NAME
    AND refs.COLUMN_NAME=cols.COLUMN_NAME
LEFT JOIN INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS AS cRefs
ON cRefs.CONSTRAINT_SCHEMA=cols.TABLE_SCHEMA
    AND cRefs.CONSTRAINT_NAME=refs.CONSTRAINT_NAME
LEFT JOIN INFORMATION_SCHEMA.`KEY_COLUMN_USAGE` AS links
ON links.TABLE_SCHEMA=cols.TABLE_SCHEMA
    AND links.REFERENCED_TABLE_SCHEMA=cols.TABLE_SCHEMA
    AND links.REFERENCED_TABLE_NAME=cols.TABLE_NAME
    AND links.REFERENCED_COLUMN_NAME=cols.COLUMN_NAME
LEFT JOIN INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS AS cLinks
ON cLinks.CONSTRAINT_SCHEMA=cols.TABLE_SCHEMA
    AND cLinks.CONSTRAINT_NAME=links.CONSTRAINT_NAME
WHERE cols.TABLE_SCHEMA=DATABASE()
    AND cols.TABLE_NAME="table"

Shows the latest file with human readable timestamp:

find . -type f -printf '%TY-%Tm-%Td %TH:%TM: %Tz %p\n'| sort -n | tail -n1

Result looks like this:

2015-10-06 11:30: +0200 ./foo/bar.txt

To show more files, replace -n1 with a higher number

You can use Substring:

string b = a.Substring(0,3);

You could just use an even simpler typedef:

typedef char *string;

Then, your malloc would look like a usual malloc:

string s = malloc(maxStringLength);

If you are not able to access tomcat from remote, there might be reason that taken port is not open in your machine. Suppose you have taken 8081 port.

On Your windows machine:

Open Control panel-> windows Firewall-> Advance setting->Inbound Rules

Create a new rule: mention Port

Configure your port and then shutdown and start your tomcat and it will be accessible from remote as well.

That port issue majorly comes in AWS machines.

If it is still not working then please check with your administrator that selected port is open for public access or not, if not then open it.

Just to add some other things to watch out for:

• Sudo in a init.d script is no good since it needs a tty ("sudo: sorry, you must have a tty to run sudo")
• If you are daemonizing a java application, you might want to consider Java Service Wrapper (which provides a mechanism for setting the user id)
• Another alternative could be su --session-command=[cmd] [user]

Swift 3.0

if let url = URL(string: "https://www.reddit.com") {
    if #available(iOS 10.0, *) {
        UIApplication.shared.open(url, options: [:])
    } else {
        UIApplication.shared.openURL(url)
    }
}

This supports devices running older versions of iOS as well

Short Answer

Yes.

Explanation

It is a good practice since an element can be a part of different groups, and you may want specific elements to be a part of more than one group. The element can hold an infinite number of classes in HTML5, while in HTML4 you are limited by a specific length.

The following example will show you the use of multiple classes.

The first class makes the text color red.

The second class makes the background-color blue.

See how the DOM Element with multiple classes will behave, it will wear both CSS statements at the same time.

Result: multiple CSS statements in different classes will stack up.

You can read more about CSS Specificity.

CSS

.class1 {
    color:red;
}

.class2 {
    background-color:blue;
}

HTML

<div class="class1">text 1</div>
<div class="class2">text 2</div>
<div class="class1 class2">text 3</div>

Are you trying to get visitors to old.com/about.htm to go to new.com/about.htm? If so, you can do this with a mod_rewrite rule in .htaccess:

RewriteEngine on

RewriteRule ^(.*)$ http://www.thenewdomain.com/$1 [R=permanent,L]

 $curl = curl_init();
 curl_setopt_array($curl, array(
            CURLOPT_URL => "http://example.com",
            CURLOPT_RETURNTRANSFER => true,
            CURLOPT_ENCODING => "",
            CURLOPT_MAXREDIRS => 10,
            CURLOPT_TIMEOUT => 30,
            CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
            CURLOPT_CUSTOMREQUEST => "POST",
            CURLOPT_POSTFIELDS => "value1=111&value2=222",
            CURLOPT_HTTPHEADER => array(
                "cache-control: no-cache",
                "content-type: application/x-www-form-urlencoded"
            ),
        ));
 $response = curl_exec($curl);
 $err = curl_error($curl);

 curl_close($curl);

 if (!$err)
 {
      var_dump($response);
 }

None of these answers actually solve 100% of the problem. mjj1409 gets most of it, but conveniently avoids the issue of logging the response, which takes a bit more work. Paul Sabou provides a solution that seems realistic, but doesn't provide enough details to actually implement (and it didn't work at all for me). Sofiene got the logging but with a critical problem: the response is no longer readable because the input stream has already been consumed!

I recommend using a BufferingClientHttpResponseWrapper to wrap the response object to allow reading the response body multiple times:

public class LoggingRequestInterceptor implements ClientHttpRequestInterceptor {

    private static final Logger logger = LoggerFactory.getLogger(LoggingRequestInterceptor.class);

    @Override
    public ClientHttpResponse intercept(final HttpRequest request, final byte[] body,
            final ClientHttpRequestExecution execution) throws IOException {
        ClientHttpResponse response = execution.execute(request, body);

        response = log(request, body, response);

        return response;
    }

    private ClientHttpResponse log(final HttpRequest request, final byte[] body, final ClientHttpResponse response) {
        final ClientHttpResponse responseCopy = new BufferingClientHttpResponseWrapper(response);
        logger.debug("Method: ", request.getMethod().toString());
        logger.debug("URI: ", , request.getURI().toString());
        logger.debug("Request Body: " + new String(body));
        logger.debug("Response body: " + IOUtils.toString(responseCopy.getBody()));
        return responseCopy;
    }

}

This will not consume the InputStream because the response body is loaded into memory and can be read multiple times. If you do not have the BufferingClientHttpResponseWrapper on your classpath, you can find the simple implementation here:

https://github.com/spring-projects/spring-android/blob/master/spring-android-rest-template/src/main/java/org/springframework/http/client/BufferingClientHttpResponseWrapper.java

For setting up the RestTemplate:

LoggingRequestInterceptor loggingInterceptor = new LoggingRequestInterceptor();
restTemplate.getInterceptors().add(loggingInterceptor);

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo")

int average_in_int = ( (Double) Math.ceil( sum/count ) ).intValue();

Note that you can also use the C99 fixed-width types perfectly well in Objective-C:

#import <stdint.h>
...
int32_t x; // guaranteed to be 32 bits on any platform

The wikipedia page has a decent description of what's available in this header if you don't have a copy of the C standard (you should, though, since Objective-C is just a tiny extension of C). You may also find the headers limits.h and inttypes.h to be useful.

The guarantee you get is that sizeof(char) == 1. There are no other guarantees, including no guarantee that sizeof(int *) == sizeof(double *).

In practice, pointers will be size 2 on a 16-bit system (if you can find one), 4 on a 32-bit system, and 8 on a 64-bit system, but there's nothing to be gained in relying on a given size.

Python with PHP flavor:

def is_array(var):
    return isinstance(var, (list, tuple))

This problem occur due to wrong spell or undefined database name. Make sure your database name, table name and all column name is same as from phpmyadmin.

Thank You

I'd rather use static widths and if you'd like your page to resize depending on screen size, you can have a look at media queries.

Or, you can set a min-width on elements like header, navigation, content etc.

You can hide the "Watch Later" Button by using "Youtube-nocookie" (this will not hide the share Button)

Adding controls=0 will also remove the video control bar at the bottom of the screen and using modestbranding=1 will remove the youtube logo at bottom right of the screen

However using them both doesn't works as expected (it only hides the video control bar)

<iframe width="100%" height="100%" src="https://www.youtube-nocookie.com/embed/fNb-DTEb43M?controls=0" frameborder="0" allowfullscreen></iframe>

In Controller

return redirect()->route('company')->with('update', 'Content has been updated successfully!');

In view

@if (session('update'))
  <div class="alert alert-success alert-dismissable custom-success-box" style="margin: 15px;">
     <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
     <strong> {{ session('update') }} </strong>
  </div>
@endif

Clean : Shift-Command-K is what works for me.

The SpecialCells Does not actually work as it needs to be continuous. I have solved this by adding a sort funtion in order to sort the data based on the coloumns i need.

Sorry for no comments on the code as i was not planning to share it:

Sub testtt()
    arr = FilterAndGetData(Worksheets("Data").range("A:K"), Array(1, 9), Array("george", "WeeklyCash"), Array(1, 2, 3, 10, 11), 1)
    Debug.Print sms(arr)
End Sub
Function FilterAndGetData(ByVal rng As Variant, ByVal fields As Variant, ByVal criterias As Variant, ByVal colstoreturn As Variant, ByVal headers As Boolean) As Variant
Dim SUset, EAset, CMset
If Application.ScreenUpdating Then Application.ScreenUpdating = False: SUset = False Else SUset = True
If Application.EnableEvents Then Application.EnableEvents = False: EAset = False Else EAset = True
If Application.Calculation = xlCalculationAutomatic Then Application.Calculation = xlCalculationManual: CMset = False Else CMset = True
For Each col In rng.Columns: col.Hidden = False: Next col

Dim oldsheet, scol, ecol, srow, hyesno As String
Dim i, counter As Integer

oldsheet = ActiveSheet.Name


Worksheets(rng.Worksheet.Name).Activate

Worksheets(rng.Worksheet.Name).AutoFilterMode = False

scol = Chr(rng.Column + 64)
ecol = Chr(rng.Columns.Count + rng.Column + 64 - 1)
srow = rng.row

If UBound(fields) - LBound(fields) <> UBound(criterias) - LBound(criterias) Then FilterAndGetData = "Fields&Crit. counts dont match": GoTo done

dd = sortrange(rng, colstoreturn, headers)

For i = LBound(fields) To UBound(fields)
    rng.AutoFilter Field:=CStr(fields(i)), Criteria1:=CStr(criterias(i))
Next i

Dim rngg As Variant

rngg = rng.SpecialCells(xlCellTypeVisible)
Debug.Print ActiveSheet.AutoFilter.range.address
FilterAndGetData = ActiveSheet.AutoFilter.range.SpecialCells(xlCellTypeVisible).Value

For Each row In rng.Rows
    If row.EntireRow.Hidden Then Debug.Print yes
Next row


done:
    'Worksheets("Data").AutoFilterMode = False
    Worksheets(oldsheet).Activate
    If SUset Then Application.ScreenUpdating = True
    If EAset Then Application.EnableEvents = True
    If CMset Then Application.Calculation = xlCalculationAutomatic
End Function
Function sortrange(ByVal rng As Variant, ByVal colnumbers As Variant, ByVal headers As Boolean)

    Dim SUset, EAset, CMset
    If Application.ScreenUpdating Then Application.ScreenUpdating = False: SUset = False Else SUset = True
    If Application.EnableEvents Then Application.EnableEvents = False: EAset = False Else EAset = True
    If Application.Calculation = xlCalculationAutomatic Then Application.Calculation = xlCalculationManual: CMset = False Else CMset = True
    For Each col In rng.Columns: col.Hidden = False: Next col

    Dim oldsheet, scol, srow, sortcol, hyesno As String
    Dim i, counter As Integer
    oldsheet = ActiveSheet.Name
    Worksheets(rng.Worksheet.Name).Activate
    Worksheets(rng.Worksheet.Name).AutoFilterMode = False
    scol = rng.Column
    srow = rng.row

    If headers Then hyesno = xlYes Else hyesno = xlNo

    For i = LBound(colnumbers) To UBound(colnumbers)
        rng.Sort key1:=range(Chr(scol + colnumbers(i) + 63) + CStr(srow)), order1:=xlAscending, Header:=hyesno
    Next i
    sortrange = "123"
done:
    Worksheets(oldsheet).Activate
    If SUset Then Application.ScreenUpdating = True
    If EAset Then Application.EnableEvents = True
    If CMset Then Application.Calculation = xlCalculationAutomatic
End Function

You can use following code too:

 foreach (var item in listBox1.Items.Cast<string>().ToList())
 {
     string removelistitem = "OBJECT";
     if (item.Contains(removelistitem))
     {
        listBox1.Items.Remove(item);
     }
 }

I done this way:

$scope.printDiv = function (div) {
  var docHead = document.head.outerHTML;
  var printContents = document.getElementById(div).outerHTML;
  var winAttr = "location=yes, statusbar=no, menubar=no, titlebar=no, toolbar=no,dependent=no, width=865, height=600, resizable=yes, screenX=200, screenY=200, personalbar=no, scrollbars=yes";

  var newWin = window.open("", "_blank", winAttr);
  var writeDoc = newWin.document;
  writeDoc.open();
  writeDoc.write('<!doctype html><html>' + docHead + '<body onLoad="window.print()">' + printContents + '</body></html>');
  writeDoc.close();
  newWin.focus();
}

Use Elastic Load Balacing, it supports SSL termination at the Load Balancer, including offloading SSL decryption from application instances and providing centralized management of SSL certificates.

$('.class1, .class2').click(some_function);

Make sure you put a space like $('.class1,space here.class2') or else it won't work.

This is based off of Erik's answer from earlier, but I've found it easiest to read in the .csv file using pandas and then create a new instance of the class for every row in the in data frame.

This example is updated using iloc as pandas no longer uses ix in the most recent version. I don't know about Erik's situation but you need to create the list outside of the for loop otherwise it will not append to your array but simply overwrite it.

import pandas as pd
df = pd.read_csv('path_to_file', sep='delimiter')
products = []
for i in range(len(df)):
    products.append(
        Product(
        name=df.iloc[i][0]
        description=df.iloc[i][1]
        price=df.iloc[i][2]
        )
    )
Product.objects.bulk_create(products)

This is just breaking the DataFrame into an array of rows and then selecting each column out of that array off the zero index. (i.e. name is the first column, description the second, etc.)

Hope that helps.

This is a fairly comprehensive list from the Eclipse documentation. If anyone knows of another list — maybe with more details, or just the most common icons — feel free to add it.

If you're a Subversion user, the icons you're looking for may actually belong to Subclipse; see this excellent answer for more on those.

For ASP.NET MVC if you want to make an exception for leaving the page via submitting a particular form:

Set a form id:

@using (Html.BeginForm("Create", "MgtJob", FormMethod.Post, new { id = "createjob" }))
{
  // Your code
}



<script type="text/javascript">

  // Without submit form
   $(window).bind('beforeunload', function () {
        if ($('input').val() !== '') {
            return "It looks like you have input you haven't submitted."
        }
    });

    // this will call before submit; and it will unbind beforeunload
    $(function () {
        $("#createjob").submit(function (event) {
            $(window).unbind("beforeunload");
        });
    });

</script>

The problem is the length of the filenames. The first filename is only 7 chars long, so the tab occurs at char 8 (doing a tab after every 4 characters). However the next filenames are 8 chars long, so the next tab won't be until char 12. And if you had filenames longer than 11 chars, you'd run into the same problem again.

Could you not use typeof(object) to compare against

I think you hit the same issue as discussed in this post. You forgot to escape your \ character.

View-Page

<h:selectOneMenu id="selectOneCB" value="#{page.selectedName}">
     <f:selectItems value="#{page.names}"/>
</h:selectOneMenu>

Backing-Bean

   List<SelectItem> names = new ArrayList<SelectItem>();

   //-- Populate list from database

   names.add(new SelectItem(valueObject,"label"));

   //-- setter/getter accessor methods for list

To display particular selected record, it must be one of the values in the list.

df.index.name should do the trick.

Python has a dir function that let's you query object attributes. dir(df.index) was helpful here.

According to wikipedia article on status codes. Nginx has a custom error code when http traffic is sent to https port(error code 497)

And according to nginx docs on error_page, you can define a URI that will be shown for a specific error.
Thus we can create a uri that clients will be sent to when error code 497 is raised.

nginx.conf

#lets assume your IP address is 89.89.89.89 and also 
#that you want nginx to listen on port 7000 and your app is running on port 3000

server {
    listen 7000 ssl;
 
    ssl_certificate /path/to/ssl_certificate.cer;
    ssl_certificate_key /path/to/ssl_certificate_key.key;
    ssl_client_certificate /path/to/ssl_client_certificate.cer;

    error_page 497 301 =307 https://89.89.89.89:7000$request_uri;

    location / {
        proxy_pass http://89.89.89.89:3000/;

        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Protocol $scheme;
    }
}

However if a client makes a request via any other method except a GET, that request will be turned into a GET. Thus to preserve the request method that the client came in via; we use error processing redirects as shown in nginx docs on error_page

And thats why we use the 301 =307 redirect.

Using the nginx.conf file shown here, we are able to have http and https listen in on the same port

The Question already has been answered in detail. I still want to add something that seems very surprising to me:

The "gradle dependencies" task does not list any file dependencies. Even though you might think so, as they have been specified in the "dependencies" block after all..

So don't rely on the output of this to check whether your referenced local lib files are working correctly.

If anyone wants to get only the selected value on click to an option, he can do the follow:

$('.chosen-select').on('change', function(evt, params) {
    var selectedValue = params.selected;
    console.log(selectedValue);
});

Such type of encoding are usually part of numpy array. If you are using a numpy array like this :

a = np.array([1,0,3])

then there is very simple way to convert that to 1-hot encoding

out = (np.arange(4) == a[:,None]).astype(np.float32)

That's it.

Manually editing firefox's settings is the way to go, but it's inconvenient when you need to do it often.

Instead, you can install an add-on that will do it for you in one click.

I use CORS everywhere, which works great for me.

Here is a link to the installer

I figured out that the plt.pause(0.001) command is the only thing needed and nothing else.

plt.show() and plt.draw() are unnecessary and / or blocking in one way or the other. So here is a code that draws and updates a figure and keeps going. Essentially plt.pause(0.001) seems to be the closest equivalent to matlab's drawnow.

Unfortunately those plots will not be interactive (they freeze), except you insert an input() command, but then the code will stop.

The documentation of the plt.pause(interval) command states:

If there is an active figure, it will be updated and displayed before the pause...... This can be used for crude animation.

and this is pretty much exactly what we want. Try this code:

import numpy as np
from matplotlib import pyplot as plt

x = np.arange(0, 51)               # x coordinates  
         
for z in range(10, 50):

    y = np.power(x, z/10)          # y coordinates of plot for animation

    plt.cla()                      # delete previous plot
    plt.axis([-50, 50, 0, 10000])  # set axis limits, to avoid rescaling
    plt.plot(x, y)                 # generate new plot
    plt.pause(0.1)                 # pause 0.1 sec, to force a plot redraw
