JSON strings must use double quotes. The JSON python library enforces this so you are unable to load your string. Your data needs to look like this:

{"http://example.org/about": {"http://purl.org/dc/terms/title": [{"type": "literal", "value": "Anna's Homepage"}]}}

If that's not something you can do, you could use ast.literal_eval() instead of json.loads()

There are several libraries available solving this problem, but the simplest is probably to use Boost Tokenizer:

#include <iostream>
#include <string>
#include <boost/tokenizer.hpp>
#include <boost/foreach.hpp>

typedef boost::tokenizer<boost::char_separator<char> > tokenizer;

std::string str("denmark;sweden;india;us");
boost::char_separator<char> sep(";");
tokenizer tokens(str, sep);

BOOST_FOREACH(std::string const& token, tokens)
{
    std::cout << "<" << *tok_iter << "> " << "\n";
}

Because its primary use is displaying numbers? If you want to round numbers, use Math.round() with apropriate factors.

$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);

This would work

setInterval(function(){$("#myButtonId").click();}, 1000);

What is the type of c.PhysicalAddresses? If it's Dictionary<TKey,TValue>, then you can use the ContainsKey method.

If you are using Python 3, you can use urllib.parse

url = """example.com?title=%D0%BF%D1%80%D0%B0%D0%B2%D0%BE%D0%B2%D0%B0%D1%8F+%D0%B7%D0%B0%D1%89%D0%B8%D1%82%D0%B0"""

import urllib.parse
urllib.parse.unquote(url)

gives:

'example.com?title=????????+??????'

git revert makes a new commit

git revert simply creates a new commit that is the opposite of an existing commit.

It leaves the files in the same state as if the commit that has been reverted never existed. For example, consider the following simple example:

$ cd /tmp/example
$ git init
Initialized empty Git repository in /tmp/example/.git/
$ echo "Initial text" > README.md
$ git add README.md
$ git commit -m "initial commit"
[master (root-commit) 3f7522e] initial commit
 1 file changed, 1 insertion(+)
 create mode 100644 README.md
$ echo "bad update" > README.md 
$ git commit -am "bad update"
[master a1b9870] bad update
 1 file changed, 1 insertion(+), 1 deletion(-)

In this example the commit history has two commits and the last one is a mistake. Using git revert:

$ git revert HEAD
[master 1db4eeb] Revert "bad update"
 1 file changed, 1 insertion(+), 1 deletion(-)

There will be 3 commits in the log:

$ git log --oneline
1db4eeb Revert "bad update"
a1b9870 bad update
3f7522e initial commit

So there is a consistent history of what has happened, yet the files are as if the bad update never occured:

cat README.md 
Initial text

It doesn't matter where in the history the commit to be reverted is (in the above example, the last commit is reverted - any commit can be reverted).

Closing questions

do you have to do something else after?

A git revert is just another commit, so e.g. push to the remote so that other users can pull/fetch/merge the changes and you're done.

Do you have to commit the changes revert made or does revert directly commit to the repo?

git revert is a commit - there are no extra steps assuming reverting a single commit is what you wanted to do.

Obviously you'll need to push again and probably announce to the team.

Indeed - if the remote is in an unstable state - communicating to the rest of the team that they need to pull to get the fix (the reverting commit) would be the right thing to do :).

Try using exit(0); instead. The exit function expects an integer parameter. And don't forget to #include <stdlib.h>.

try this:

SELECT ReportId, Email = 
    STUFF((SELECT ', ' + Email
           FROM your_table b 
           WHERE b.ReportId = a.ReportId 
          FOR XML PATH('')), 1, 2, '')
FROM your_table a
GROUP BY ReportId

i wrote a helper method to help me go through all my selected elements and remove the active class.

    function removeClassFromElem(classSelect, classToRemove){
      $(classSelect).each(function(){
        var currElem=$(this);
        if(currElem.hasClass(classToRemove)){
          currElem.removeClass(classToRemove);
        }
      });
    }

    //usage
    removeClassFromElem('.someclass', 'active');

no one says that you also have to have mod_headers enabled, so if still not working, try this:

(following tips works on Ubuntu, don't know about other distributions)

you can check list of loaded modules with

apache2ctl -M

to enable mod_headers you can use

a2enmod headers

of course after any changes in Apache you have to restart it:

/etc/init.d/apache2 restart

Then you can use

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>

And if mod_headers is not active, this line will do nothing at all. You can try skip if clause and just add Header set Access-Control-Allow-Origin "*" in your config, then it should throw error during start if mod_headers is not active.

The very simplest way would be to run Eclipse CDT on the Linux Box and use either X11-Forwarding or remote desktop software such as VNC.

This, of course, is only possible when you Eclipse is present on the Linux box and your network connection to the box is sufficiently fast.

The advantage is that, due to everything being local, you won't have synchronization issues, and you don't get any awkward cross-platform issues.

If you have no eclipse on the box, you could thinking of sharing your linux working directory via SMB (or SSHFS) and access it from your windows machine, but that would require quite some setup.

Both would be better than having two copies, especially when it's cross-platform.

Paths under linux are separated by colons (:), not semi-colons (;), as theatrus correctly used it in his example. I believe Java respects this convention.

Edit

Alternatively to what andy suggested, you may use the following form (which sets CLASSPATH for the duration of the command):

CLASSPATH=".:../somejar.jar:../mysql-connector-java-5.1.6-bin.jar" java -Xmx500m ...

whichever is more convenient to you.

I've used the following JavaScript library with great success:

https://github.com/balupton/jquery-history

It supports the HTML5 history API as well as a fallback method (using #) for older browsers.

This library is essentially a polyfill around `history.pushState'.

you can do this with css3, this blurs the whole element

div (or whatever element) {
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
  filter: blur(5px);
}

To accessing member functions or variables from one scope to another scope (In your case one method to another method we need to refer method or variable with class object. and you can do it by referring with self keyword which refer as class object.

class YourClass():

    def your_function(self, *args):

        self.callable_function(param) # if you need to pass any parameter

    def callable_function(self, *params): 
        print('Your param:', param)

You can use javac *.java command to compile all you java sources. Also you should learn a little about classpath because it seems that you should set appropriate classpath for succesful compilation (because your IDE use some libraries for building WebService clients). Also I can recommend you to check wich command your IDE use to build your project.

Quoting the iPhone OS Technology Overview:

iPhone OS provides support for full-screen video playback through the Media Player framework (MediaPlayer.framework). This framework supports the playback of movie files with the .mov, .mp4, .m4v, and .3gp filename extensions and using the following compression standards:

• H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H.264 Baseline Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
• H.264 video, up to 768 Kbps, 320 by 240 pixels, 30 frames per second, Baseline Profile up to Level 1.3 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
• MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
• Numerous audio formats, including the ones listed in “Audio Technologies”

For information about the classes of the Media Player framework, see Media Player Framework Reference.

Use:

$postvalue = array("a", "b", "c");
foreach($postvalue as $value)
{
    echo '<input type="hidden" name="result[]" value="'. $value. '">';
}

And you will get $_POST['result'] as an array.

print_r($_POST['result']);

Try using a div instead of the span or using the CSS display: block; or display: inline-block;—span is by default an inline element which cannot take width and height properties.

A hidden attribute is a boolean attribute (True/False). When this attribute is used on an element, it removes all relevance to that element. When a user views the html page, elements with the hidden attribute should not be visible.

Example:

    <p hidden>You can't see this</p>

Aria-hidden attributes indicate that the element and ALL of its descendants are still visible in the browser, but will be invisible to accessibility tools, such as screen readers.

Example:

    <p aria-hidden="true">You can't see this</p>

Take a look at this. It should answer all your questions.

Note: ARIA stands for Accessible Rich Internet Applications

you are confusing the concept of appending and prepending. the following code is prepending:

sys.path.insert(1,'/thePathToYourFolder/')

it places the new information at the beginning (well, second, to be precise) of the search sequence that your interpreter will go through. sys.path.append() puts things at the very end of the search sequence.

it is advisable that you use something like virtualenv instead of manually coding your package directories into the PYTHONPATH everytime. for setting up various ecosystems that separate your site-packages and possible versions of python, read these two blogs:

1. python ecosystems introduction

2. bootstrapping python virtual environments

if you do decide to move down the path to environment isolation you would certainly benefit by looking into virtualenvwrapper: http://www.doughellmann.com/docs/virtualenvwrapper/

My 5 cents (because it appears more straightforward/simpler and sufficient for short lists):

public static T Median<T>(this IEnumerable<T> items)
{
    var i = (int)Math.Ceiling((double)(items.Count() - 1) / 2);
    if (i >= 0)
    {
        var values = items.ToList();
        values.Sort();
        return values[i];
    }

    return default(T);
}

P.S. using "higher median" as described by ShitalShah.

First of all, input element shouldn't have a closing tag (from http://www.w3.org/TR/html401/interact/forms.html#edef-INPUT : End tag: forbidden ).

Second thing, you need the after(), not append() function.

I have not tried, but if you know Perl you can use the Parse-Stata-DtaReader module to convert the file for you.

The module has a command-line tool dta2csv, which can "convert Stata 8 and Stata 10 .dta files to csv"

Hopefully a simple explanation : -

onStart() -> called when the activity becomes visible, but might not be in the foreground (e.g. an AlertFragment is on top or any other possible use case).

onResume() -> called when the activity is in the foreground, or the user can interact with the Activity.

Try this

$("#mydiv div.myclass")

No, Static member function can't be virtual .since virtual concept is resolved at run time with the help of vptr, and vptr is non static member of a class.due to that static member function can't acess vptr so static member can't be virtual.

I have found it satisfactory to use ls and cd within ipython notebook to find the file. Then type cat your_file_name into the cell, and you'll get back the contents of the file, which you can then paste into the cell as code.

something like:

DELIMITER //

CREATE PROCEDURE alluser()
BEGIN
   SELECT *
   FROM users;
END //

DELIMITER ;

than:

SHOW CREATE PROCEDURE alluser

gives result:

'alluser', 'STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER', 'CREATE DEFINER=`root`@`localhost` PROCEDURE `alluser`()
BEGIN
   SELECT *
   FROM users;
END'

Here is a generic and relatively fast solution that outputs integers from 1 to @n. It works with any positive integer of @n (very large numbers will cause arithmetic overflow) without needing to add or remove table joins. It doesn't require the use of system tables nor do you to change max recursions.

declare @n int = 10000 

;with d as (select * from (values (0),(1),(2),(3),(4),(5),(6),(7),(8),(9)) x (d)),
n as ( 
    select d x from d where d > 0 and d <= @n
    union all
    select x * 10 + d from n, d where x * 10 + d <= @n
)
select x from n 

You can add an order by clause to sort the numbers.

This is my 2 cents for adatetime string. On MM DD YYYY systems switch the first and second %DATE:~ entries.

    REM ====================================================================================
    REM CHECK for SHORTDATE dd DDxMMxYYYY 
    IF "%DATE:~0,1%" GTR "3" (
        SET DATETIME=%DATE:~9,4%%DATE:~6,2%%DATE:~3,2%%TIME:~0,2%%TIME:~3,2%%TIME:~6,2%
    ) ELSE (
    REM ASSUMES SHORTDATE DDxMMxYYYY
        SET DATETIME=%DATE:~6,4%%DATE:~3,2%%DATE:~0,2%%TIME:~0,2%%TIME:~3,2%%TIME:~6,2%
        )
    REM CORRECT FOR HOURS BELOW 10

    ECHO %DATETIME%

Assuming you are using MagicalRecord and have a default persistence store:

I don't like all the solutions that assume certain files to exist and/or demand entering the entities names or classes. This is a Swift(2), safe way to delete all the data from all the entities. After deleting it will recreate a fresh stack too (I am actually not sure as to how neccessery this part is).

It's godo for "logout" style situations when you want to delete everything but have a working store and moc to get new data in (once the user logs in...)

extension NSManagedObject {

    class func dropAllData() {

        MagicalRecord.saveWithBlock({ context in

            for name in NSManagedObjectModel.MR_defaultManagedObjectModel().entitiesByName.keys {
                do { try self.deleteAll(name, context: context) }
                catch { print("?? ?? Error when deleting \(name): \(error)") }
            }

            }) { done, err in
                MagicalRecord.cleanUp()
                MagicalRecord.setupCoreDataStackWithStoreNamed("myStoreName")
        }
    }

    private class func deleteAll(name: String, context ctx: NSManagedObjectContext) throws {
        let all = NSFetchRequest(entityName: name)
        all.includesPropertyValues = false

        let allObjs = try ctx.executeFetchRequest(all)
        for obj in allObjs {
            obj.MR_deleteEntityInContext(ctx)
        }

    }
}

impossible with javascript. Just as another alternative to suggestions from other answers: consider using jGrowl: http://archive.plugins.jquery.com/project/jGrowl

        if(keyCode == KeyEvent.VK_F5)
            message = "Pressed: " + KeyEvent.getKeyText(keyCode);

You can set the Property FormBorderStyle to none in the designer, or in code:

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

To replace more than one number:

vec <- 1:10
replace(vec, vec== c(2,6), c(0,9)) #2 and 6 will be replaced by 0 and 9.

Edit:

for a continous series, you can do this vec <- c(1:10); replace(vec, vec %in% c(2,6), c(0,9)) but for vec <- c(1:10,2,2,2); replace(vec, vec %in% c(2,6), 0) we can replace multiple values with one value.

Here are 3 ways.

//array of Characters
let charArr1 = [Character](myString)

//array of String.element
let charArr2 = Array(myString)

for char in myString {
  //char is of type Character
}

In some cases, what people really want is a way to convert a string into an array of little strings with 1 character length each. Here is a super efficient way to do that:

//array of String
var strArr = myString.map { String($0)}

Swift 3

Here are 3 ways.

let charArr1 = [Character](myString.characters)
let charArr2 = Array(myString.characters)
for char in myString.characters {
  //char is of type Character
}

In some cases, what people really want is a way to convert a string into an array of little strings with 1 character length each. Here is a super efficient way to do that:

var strArr = myString.characters.map { String($0)}

Or you can add an extension to String.

extension String {
   func letterize() -> [Character] {
     return Array(self.characters)
  }
}

Then you can call it like this:

let charArr = "Cat".letterize()

You can also use number formatter JS available at

https://code.google.com/p/javascript-number-formatter/

  format("#,###.", 8211)

If the use case is storing data in a collection then ECMAScript 6 provides the Map type.

It's only heavier to initialize.

Here is an example:

const map = new Map();
map.set(1, "One");
map.set(2, "Two");
map.set(3, "Three");

console.log("=== With Map ===");

for (const [key, value] of map) {
    console.log(`${key}: ${value} (${typeof(key)})`);
}

console.log("=== With Object ===");

const fakeMap = {
    1: "One",
    2: "Two",
    3: "Three"
};

for (const key in fakeMap) {
    console.log(`${key}: ${fakeMap[key]} (${typeof(key)})`);
}

Result:

=== With Map ===
1: One (number)
2: Two (number)
3: Three (number)
=== With Object ===
1: One (string)
2: Two (string)
3: Three (string)

I know it's a bit late and maybe you already, indirectly, said it, but again, Kafka is not a queue at all, it's a log (as someone said above, poll based).

To make it simple, the most obvious use case when you should prefer RabbitMQ (or any queue techno) over Kafka is the following one :

You have multiple consumers consuming from a queue and whenever there is a new message in the queue and an available consumer, you want this message to be processed. If you look closely at how Kafka works, you'll notice it does not know how to do that, because of partition scaling, you'll have a consumer dedicated to a partition and you'll get into starvation issue. Issue that is easily avoided by using simple queue techno. You can think of using a thread that will dispatch the different messages from same partition, but again, Kafka does not have any selective acknowledgment mechanisms.

The most you could do is doing as those guys and try to transform Kafka as a queue : https://github.com/softwaremill/kmq

Here is the step by step guide:

1. Install the GitLens extension: GitLens

2. The GitLens icon will show up in nav bar. Click on it.

   

3. Click on compare

   

4. Select branches to compare

   

5. Now you can see the difference. You can select any file for which you want to see the diff for.

   

Following should work. I have verified. May be your problem is somewhere else.

Receiver:

public class MyReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        if (Intent.ACTION_BOOT_COMPLETED.equals(arg1.getAction())) {
            Log.d("TAG", "MyReceiver");
            Intent serviceIntent = new Intent(context, Test1Service.class);
            context.startService(serviceIntent);
        }
    }
}

Service:

public class Test1Service extends Service {
    /** Called when the activity is first created. */
    @Override
    public void onCreate() {
        super.onCreate();
        Log.d("TAG", "Service created.");
    }
    
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d("TAG", "Service started.");
        return super.onStartCommand(intent, flags, startId);
    }
    
    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        Log.d("TAG", "Service started.");
    }
    @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }
}

Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

In pandas 0.20.2 you can do:

from pandas.api.types import is_string_dtype
from pandas.api.types import is_numeric_dtype

is_string_dtype(df['A'])
>>>> True

is_numeric_dtype(df['B'])
>>>> True

So your code becomes:

for y in agg.columns:
    if (is_string_dtype(agg[y])):
        treat_str(agg[y])
    elif (is_numeric_dtype(agg[y])):
        treat_numeric(agg[y])

THE EASIEST SOLUTION

It will add an extra in your options but your problem will be solved.

<?php 
    if ($editing == Yes) {
        echo "<option value=\".$MyValue.\" SELECTED>".$MyValue."</option>";
    }
?>

Here is a solution without relying on any server-side control, just like OP has described in the question.

Client side HTML code:

<form action="upload.aspx" method="post" enctype="multipart/form-data">
    <input type="file" name="UploadedFile" />
</form>

Page_Load method of upload.aspx :

if(Request.Files["UploadedFile"] != null)
{
    HttpPostedFile MyFile = Request.Files["UploadedFile"];
    //Setting location to upload files
    string TargetLocation = Server.MapPath("~/Files/");
    try
    {
        if (MyFile.ContentLength > 0)
        {
            //Determining file name. You can format it as you wish.
            string FileName = MyFile.FileName;
            //Determining file size.
            int FileSize = MyFile.ContentLength;
            //Creating a byte array corresponding to file size.
            byte[] FileByteArray = new byte[FileSize];
            //Posted file is being pushed into byte array.
            MyFile.InputStream.Read(FileByteArray, 0, FileSize);
            //Uploading properly formatted file to server.
            MyFile.SaveAs(TargetLocation + FileName);
        }
    }
    catch(Exception BlueScreen)
    {
        //Handle errors
    }
}

try this one:

x = document.getElementById("td35");
if (x.childElementCount > 0) {
    x = document.getElementById("LastRow");
    x.style.display = "block";
}
else {
    x = document.getElementById("LastRow");
    x.style.display = "none";
}

The problem is not that you can't forward-declare a template class. Yes, you do need to know all of the template parameters and their defaults to be able to forward-declare it correctly:

namespace std {
  template<class T, class Allocator = std::allocator<T>>
  class list;
}

But to make even such a forward declaration in namespace std is explicitly prohibited by the standard: the only thing you're allowed to put in std is a template specialisation, commonly std::less on a user-defined type. Someone else can cite the relevant text if necessary.

Just #include <list> and don't worry about it.

Oh, incidentally, any name containing double-underscores is reserved for use by the implementation, so you should use something like TEST_H instead of __TEST__. It's not going to generate a warning or an error, but if your program has a clash with an implementation-defined identifier, then it's not guaranteed to compile or run correctly: it's ill-formed. Also prohibited are names beginning with an underscore followed by a capital letter, among others. In general, don't start things with underscores unless you know what magic you're dealing with.

I resolved this issue by using ojdbc8.jar. Oracle 12c is compatible with ojdbc8.jar

I would use the Windows Scheduler to schedule a restart of your service. The problem is that you can't restart yourself, but you can stop yourself. (You've essentially sawed off the branch that you're sitting on... if you get my analogy) You need a separate process to do it for you. The Windows Scheduler is an appropriate one. Schedule a one-time task to restart your service (even from within the service itself) to execute immediately.

Otherwise, you'll have to create a "shepherding" process that does it for you.

date must be insert with two apostrophes' As example if the date is 2018/10/20. It can insert from these query

Query -

insert into run(id,name,dob)values(&id,'&name','2018-10-20')

If it's a UI based application , then " I also need to know what I need to add to my code so that my program waits about 700 milliseconds for a keyinput before moving on to another method" you can use GlassPane or Timer class to fulfill the requirement.

For key Event:

public void keyPressed(KeyEvent e) {

    int key = e.getKeyCode();

    if (key == KeyEvent.VK_LEFT) {
        dx = -1;
    }

    if (key == KeyEvent.VK_RIGHT) {
        dx = 1;
    }

    if (key == KeyEvent.VK_UP) {
        dy = -1;
    }

    if (key == KeyEvent.VK_DOWN) {
        dy = 1;
    }
}

In case you are willing to use Curl for the calls with JSON 2 and Spring 3.2.0 in hand checkout the FAQ here. As AnnotationMethodHandlerAdapter is deprecated and replaced by RequestMappingHandlerAdapter.

There isn't really a formal manual, because there's no single style or standard.

So long as you understand the rules of identifier naming you can use whatever you like.

In practice, I find it easier to use lower_case_underscore_separated_identifiers because it isn't necessary to "Double Quote" them everywhere to preserve case, spaces, etc.

If you wanted to name your tables and functions "@MyA??! ""betty"" Shard$42" you'd be free to do that, though it'd be pain to type everywhere.

The main things to understand are:

• Unless double-quoted, identifiers are case-folded to lower-case, so MyTable, MYTABLE and mytable are all the same thing, but "MYTABLE" and "MyTable" are different;

• Unless double-quoted:

  SQL identifiers and key words must begin with a letter (a-z, but also letters with diacritical marks and non-Latin letters) or an underscore (_). Subsequent characters in an identifier or key word can be letters, underscores, digits (0-9), or dollar signs ($).

• You must double-quote keywords if you wish to use them as identifiers.

In practice I strongly recommend that you do not use keywords as identifiers. At least avoid reserved words. Just because you can name a table "with" doesn't mean you should.

Delete all related pod files:

• xx.xcworkspace
• Podfile
• Podfile.lock

and in the Project Navigator:

Click on the project name (blue icon) --> Targets (*) --> Build Phases --> Remove "[CP] Check Pods manifests.lock" (click on the "x")

(*) Click on the project name, you might have to click on "Show project and target list" to see the side bar first.

You can get the functionality you want by sourcing the script instead of running it. eg:

$cat script
cmd1
cmd2
$ . script
$ at this point cmd1 and cmd2 have been run inside this shell

Objective-C

Based on Tai Le answer up there which implements the feature inside an IB Designable, here's the Objective-C version.

Put this in YourLabel.h

@interface YourLabel : UILabel

@property IBInspectable CGFloat topInset;
@property IBInspectable CGFloat bottomInset;
@property IBInspectable CGFloat leftInset;
@property IBInspectable CGFloat rightInset;

@end

And this would go in YourLabel.m

IB_DESIGNABLE

@implementation YourLabel

#pragma mark - Super

- (instancetype)initWithCoder:(NSCoder *)aDecoder {
    self = [super initWithCoder:aDecoder];
    if (self) {
        self.topInset = 0;
        self.bottomInset = 0;
        self.leftInset = 0;
        self.rightInset = 0;
    }
    return self;
}

- (void)drawTextInRect:(CGRect)rect {
    UIEdgeInsets insets = UIEdgeInsetsMake(self.topInset, self.leftInset, self.bottomInset, self.rightInset);
    [super drawTextInRect:UIEdgeInsetsInsetRect(rect, insets)];
}

- (CGSize)intrinsicContentSize {

    CGSize size = [super intrinsicContentSize];
    return CGSizeMake(size.width + self.leftInset + self.rightInset,
                      size.height + self.topInset + self.bottomInset);
}

@end

You can then modify YourLabel insets directly in Interface Builder after specifying the class inside the XIB or storyboard, the default value of the insets being zero.

Try this.

function getElementsByIdStartsWith(container, selectorTag, prefix) {
    var items = [];
    var myPosts = document.getElementById(container).getElementsByTagName(selectorTag);
    for (var i = 0; i < myPosts.length; i++) {
        //omitting undefined null check for brevity
        if (myPosts[i].id.lastIndexOf(prefix, 0) === 0) {
            items.push(myPosts[i]);
        }
    }
    return items;
}

Sample HTML Markup.

<div id="posts">
    <div id="post-1">post 1</div>
    <div id="post-12">post 12</div>
    <div id="post-123">post 123</div>
    <div id="pst-123">post 123</div>
</div>

Call it like

var postedOnes = getElementsByIdStartsWith("posts", "div", "post-");

You can use the errorPlacement option to override the error message display with little css. Because css on its own will not be enough to produce the effect you need.

$(document).ready(function(){
    $("#myForm").validate({
        rules: {
            "elem.1": {
                required: true,
                digits: true
            },
            "elem.2": {
                required: true
            }
        },
        errorElement: "div",
        wrapper: "div",  // a wrapper around the error message
        errorPlacement: function(error, element) {
            offset = element.offset();
            error.insertBefore(element)
            error.addClass('message');  // add a class to the wrapper
            error.css('position', 'absolute');
            error.css('left', offset.left + element.outerWidth());
            error.css('top', offset.top);
        }

    });
});

You can play with the left and top css attributes to show the error message on top, left, right or bottom of the element. For example to show the error on the top:

    errorPlacement: function(error, element) {
        element.before(error);
        offset = element.offset();
        error.css('left', offset.left);
        error.css('top', offset.top - element.outerHeight());
    }

And so on. You can refer to jQuery documentation about css for more options.

Here is the css I used. The result looks exactly like the one you want. With as little CSS as possible:

div.message{
    background: transparent url(msg_arrow.gif) no-repeat scroll left center;
    padding-left: 7px;
}

div.error{
    background-color:#F3E6E6;
    border-color: #924949;
    border-style: solid solid solid none;
    border-width: 2px;
    padding: 5px;
}

And here is the background image you need:

_{(source: scriptiny.com)}

If you want the error message to be displayed after a group of options or fields. Then group all those elements inside one container a 'div' or a 'fieldset'. Add a special class to all of them 'group' for example. And add the following to the begining of the errorPlacement function:

errorPlacement: function(error, element) {
    if (element.hasClass('group')){
        element = element.parent();
    }
    ...// continue as previously explained

If you only want to handle specific cases you can use attr instead:

if (element.attr('type') == 'radio'){
    element = element.parent();
}

That should be enough for the error message to be displayed next to the parent element.

You may need to change the width of the parent element to be less than 100%.

I've tried your code and it is working perfectly fine for me. Here is a preview:

I just made a very small adjustment to the message padding to make it fit in the line:

div.error {
    padding: 2px 5px;
}

You can change those numbers to increase/decrease the padding on top/bottom or left/right. You can also add a height and width to the error message. If you are still having issues, try to replace the span with a div

<div class="group">
<input type="radio" class="checkbox" value="P" id="radio_P" name="radio_group_name"/>
<label for="radio_P">P</label>
<input type="radio" class="checkbox" value="S" id="radio_S" name="radio_group_name"/>
<label for="radio_S">S</label>
</div>

And then give the container a width (this is very important)

div.group {
    width: 50px; /* or any other value */
}

About the blank page. As I said I tried your code and it is working for me. It might be something else in your code that is causing the issue.

just add reference to System.Windows.Forms.dll

If you want to select the same item in a listbox using a listview, you can use:

Private Sub ListView1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListView1.SelectedIndexChanged
    For aa As Integer = 0 To ListView1.SelectedItems.Count - 1
        ListBox1.SelectedIndex = ListView1.SelectedIndices(aa)
    Next
End Sub

You can use a dictionary too.

def install():
    print "In install"

methods = {'install': install}

method_name = 'install' # set by the command line options
if method_name in methods:
    methods[method_name]() # + argument list of course
else:
    raise Exception("Method %s not implemented" % method_name)

Simple, ORDER BY orders the data and GROUP BY groups, or combines the data.

ORDER BY orders the result set as per the mentioned field, by default in ascending order.

Suppose you are firing a query as ORDER BY (student_roll_number), it will show you result in ascending order of student's roll numbers. Here, student_roll_number entry might occur more than once.

In GROUP BY case, we use this with aggregate functions, and it groups the data as per the aggregate function, and we get the result. Here, if our query has SUM (marks) along with GROUP BY (student_first_name) it will show the sum of marks of students belonging to each group (where all members of a group will have the same first name).

Well you can remove the third calendar instance.

GregorianCalendar c1 = new GregorianCalendar();
GregorianCalendar c2 = new GregorianCalendar();
c1.set(2000, 1, 1);
c2.set(2010,1, 1);
c2.add(GregorianCalendar.MILLISECOND, -1 * c1.getTimeInMillis());

It's easier to use the timestamp for this things since Tweepy gets both

import datetime
print(datetime.datetime.fromtimestamp(int(t1)).strftime('%H:%M'))

Use ripgrep, aka rg: https://github.com/BurntSushi/ripgrep

rg --passthru...

Color is the default:

  rg -t tf -e  'key.*tfstate' -e dynamodb_table
       --passthru
       Print both matching and non-matching lines.

       Another way to achieve a similar effect is by modifying your pattern to
       match the empty string. 
       For example, if you are searching using rg foo then using 
       rg "^|foo" instead will emit every line in every file searched, but only
       occurrences of foo will be highlighted. 
       This flag enables the same behavior without needing to modify the pattern.

Sacrilege, granted, but grep has gotten complacent.

brew/apt/rpm/whatever install ripgrep

You'll never go back.

I noticed the issue the moment I updated Chrome on os x to the latest stable release (9.0.597.94) so this is a Chrome bug and hopefully will be fixed.

I'm tempted not to even attempt to work around this and just wait for the fix. It'll just mean more work taking it out.

Create a Directive with the show and size attributes ( you can add more also )

    app.directive('loader',function(){
    return {
    restrict:'EA',
    scope:{
        show : '@',
      size : '@'
    },
    template : '<div class="loader-container"><div class="loader" ng-if="show" ng-class="size"></div></div>'
  }
})

and in html use as

 <loader show="{{loader1}}" size="sm"></loader>

In the show variable pass true when any promise is running and make that false when request is completed. Active demo - Angular Loader directive example demo in JsFiddle

An alternative to System.Diagnostics.StackTrace is to use System.Environment.StackTrace which returns a string-representation of the stacktrace.

Another useful option is to use the $CALLER and $CALLSTACK debugging variables in Visual Studio since this can be enabled run-time without rebuilding the application.

Yes using Option Explicit is a good habit. Using .Select however is not :) it reduces the speed of the code. Also fully justify sheet names else the code will always run for the Activesheet which might not be what you actually wanted.

Is this what you are trying?

Option Explicit

Sub Sample()
    Dim lastRow As Long, i As Long
    Dim CopyRange As Range

    '~~> Change Sheet1 to relevant sheet name
    With Sheets("Sheet1")
        lastRow = .Range("A" & .Rows.Count).End(xlUp).Row

        For i = 2 To lastRow
            If Len(Trim(.Range("A" & i).Value)) <> 0 Then
                If CopyRange Is Nothing Then
                    Set CopyRange = .Rows(i)
                Else
                    Set CopyRange = Union(CopyRange, .Rows(i))
                End If
            Else
                Exit For
            End If
        Next

        If Not CopyRange Is Nothing Then
            '~~> Change Sheet2 to relevant sheet name
            CopyRange.Copy Sheets("Sheet2").Rows(1)
        End If
    End With
End Sub

NOTE

If if you have data from Row 2 till Row 10 and row 11 is blank and then you have data again from Row 12 then the above code will only copy data from Row 2 till Row 10

If you want to copy all rows which have data then use this code.

Option Explicit

Sub Sample()
    Dim lastRow As Long, i As Long
    Dim CopyRange As Range

    '~~> Change Sheet1 to relevant sheet name
    With Sheets("Sheet1")
        lastRow = .Range("A" & .Rows.Count).End(xlUp).Row

        For i = 2 To lastRow
            If Len(Trim(.Range("A" & i).Value)) <> 0 Then
                If CopyRange Is Nothing Then
                    Set CopyRange = .Rows(i)
                Else
                    Set CopyRange = Union(CopyRange, .Rows(i))
                End If
            End If
        Next

        If Not CopyRange Is Nothing Then
            '~~> Change Sheet2 to relevant sheet name
            CopyRange.Copy Sheets("Sheet2").Rows(1)
        End If
    End With
End Sub

Hope this is what you wanted?

Note that the if $myVar; then ... ;fi construct has a security problem you might want to avoid with

case $myvar in
  (true)    echo "is true";;
  (false)   echo "is false";;
  (rm -rf*) echo "I just dodged a bullet";;
esac

You might also want to rethink why if [ "$myvar" = "true" ] appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case solution is also handled without forks.

1. Find out where Git thinks 'origin/master' is using git-remote

git remote show origin

..which will return something like..

* remote origin
  URL: [email protected]:~/something.git
  Remote branch merged with 'git pull' while on branch master
    master
  Tracked remote branch
    master

A remote is basically a link to a remote repository. When you do..

git remote add unfuddle [email protected]/myrepo.git
git push unfuddle

..git will push changes to that address you added. It's like a bookmark, for remote repositories.

When you run git status, it checks if the remote is missing commits (compared to your local repository), and if so, by how many commits. If you push all your changes to "origin", both will be in sync, so you wont get that message.

2. If it's somewhere else, how do I turn my laptop into the 'origin/master'?

There is no point in doing this. Say "origin" is renamed to "laptop" - you never want to do git push laptop from your laptop.

If you want to remove the origin remote, you do..

git remote rm origin

This wont delete anything (in terms of file-content/revisions-history). This will stop the "your branch is ahead by.." message, as it will no longer compare your repository with the remote (because it's gone!)

One thing to remember is that there is nothing special about origin, it's just a default name git uses.

Git does use origin by default when you do things like git push or git pull. So, if you have a remote you use a lot (Unfuddle, in your case), I would recommend adding unfuddle as "origin":

git remote rm origin
git remote add origin [email protected]:subdomain/abbreviation.git

or do the above in one command using set-url:

git remote set-url origin [email protected]:subdomain/abbreviation.git

Then you can simply do git push or git pull to update, instead of git push unfuddle master

Just starting a new cmd-level from the command line gives you directly the version!

Don't live fanatically with the conventions that SUN have med up, do whats feel right to you and your team.

For example this is how eclipse do it, breaking the convention. Try adding implements Serializable and eclipse will ask to generate this line for you.

Update: There were special cases that was excluded didn't know that. I however withholds to do what you and your team seems fit.

Once you have your image, you can use

$ docker tag <image> <newName>/<repoName>:<tagName>

1. Build and tag the image with creack/node:latest

   $ ID=$(docker build -q -t creack/node .)
   

2. Add a new tag

   $ docker tag $ID creack/node:0.10.24
   

3. You can use this and skip the -t part from build

   $ docker tag $ID creack/node:latest
   

Actually, QuickSort is O(n²). Its average case running time is O(nlog(n)), but its worst-case is O(n²), which occurs when you run it on a list that contains few unique items. Randomization takes O(n). Of course, this doesn't change its worst case, it just prevents a malicious user from making your sort take a long time.

QuickSort is more popular because it:

1. Is in-place (MergeSort requires extra memory linear to number of elements to be sorted).
2. Has a small hidden constant.

Such difference between the output of du -sh and df -h may happen if some large file has been deleted, but is still opened by some process. Check with the command lsof | grep deleted to see which processes have opened descriptors to deleted files. You can restart the process and the space will be freed.

And why not just count them ?

import sys
a = sys.argv
if len(a) = 1 :  
    # No arguments were given, the program name count as one
elif len(a) = 4 :
    # Three arguments were given
else :
    # another amount of arguments was given

According to that line, type window.atob('dGhpc2lzdW5zYWZl') to your browser console and it will give you the actual passphrase.

This time the passphrase is thisisunsafe.

In Bootstrap 3.2.0 the "on" event has to be on the document and you have to empty the modal :

$(document).on("hidden.bs.modal", function (e) {
    $(e.target).removeData("bs.modal").find(".modal-content").empty();
});

In Bootstrap 3.1.0 the "on" event can be on the body :

$('body').on('hidden.bs.modal', '.modal', function () {
    $(this).removeData('bs.modal');
});

You can always create an ArrayList of Objects. But it will not be very useful to you. Suppose you have created the Arraylist like this:

List<Object> myList = new ArrayList<Object>();

and add objects to this list like this:

myList.add(new Integer("5"));

myList.add("object");

myList.add(new Object());

You won't face any problem while adding and retrieving the object but it won't be very useful. You have to remember at what location each type of object is it in order to use it. In this case after retrieving, all you can do is calling the methods of Object on them.

Wow, there are a lot of great answers to this question.

I didn't see one that takes a reduce approach so I'll add it in:

var searchForValue = 'pig';

var valueIsInArray = ['horse', 'cat', 'dog'].reduce(function(previous, current){
    return previous || searchForValue === current ? true : false;
}, false);

console.log('The value "' + searchForValue + '" is in the array: ' + valueIsInArray);

Here's a fiddle of it in action.

I found the most easiest way to find sum of all the elements of a vector

#include <iostream>
#include<vector>
using namespace std;

int main()
{
    vector<int>v(10,1);
    int sum=0;
    for(int i=0;i<v.size();i++)
    {
        sum+=v[i];
    }
    cout<<sum<<endl;

}

In this program, I have a vector of size 10 and are initialized by 1. I have calculated the sum by a simple loop like in array.

Prequisite

Having all the related projects in the same root directory.

Steps

1) First you create a new Empty project

2) Then you select the root directory of all you projects.

This will create a empty project, with a .idea directory that will simply remember the module organisation we are about to do in the next step

3) Then, in the next window, you import the different projects as modules

4) In the next window, to import each project, simply double click on the build.gradle, or pom.xml

The project will be imported as a new module.

5) Done, you now have all your projects as modules, opened on the same IntelliJ project

Apologies in advance for readability of the backticks ("`"), but these work in shells other than bash and are thus more pasteable. If you use a shell which accepts it, the $(command ...) format is much more readable (and thus debuggable) than `command ...` so feel free to modify for your sanity.

I have a simple function in my bashrc that will use awk to calculate a number of simple math items

calc(){
  awk 'BEGIN{print '"$@"' }'
}

This will do +,-,*,/,^,%,sqrt,sin,cos, parenthesis ....(and more depending on your version of awk) ... you could even get fancy with printf and format floating point output, but this is all I normally need

for this particular question, I would simply do this for each line:

calc `echo "$@"|tr " " "+"`

so the code block to sum each line would look something like this:

while read LINE || [ "$LINE" ]; do
  calc `echo "$LINE"|tr " " "+"` #you may want to filter out some lines with a case statement here
done

That's if you wanted to only sum them line by line. However for a total of every number in the datafile

VARS=`<datafile`
calc `echo ${VARS// /+}`

btw if I need to do something quick on the desktop, I use this:

xcalc() { 
  A=`calc "$@"`
  A=`Xdialog --stdout --inputbox "Simple calculator" 0 0 $A`
  [ $A ] && xcalc $A
}

There are so many solutions here, and most of them still using manual ways by downloading the package manually.

The easiest solution is actually from Navarasu.

Here is the example; and it fixes the problem quickly.

1. Download and install the package with pip

   python -m pip install webdriver-manager

Example

wolf@linux:~$ python -m pip install webdriver-manager
Collecting webdriver-manager
  Using cached https://files.pythonhosted.org/packages/9c/6c/b52517f34e907fef503cebe26c93ecdc590d0190b267d38a251a348431e8/webdriver_manager-3.2.1-py2.py3-none-any.whl

wolf@linux:~$

2. Execute it in the Python shell

from selenium import webdriver
from webdriver_manager.firefox import GeckoDriverManager

driver = webdriver.Firefox(executable_path=GeckoDriverManager().install())

Example

wolf@linux:~$ python
Python 3.7.5 (default, Nov  7 2019, 10:50:52)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
>>> from selenium import webdriver
>>> from webdriver_manager.firefox import GeckoDriverManager
>>>
>>> driver = webdriver.Firefox(executable_path=GeckoDriverManager().install())
[WDM] - There is no [linux64] geckodriver for browser  in cache
[WDM] - Getting latest mozilla release info for v0.26.0
[WDM] - Trying to download new driver from https://github.com/mozilla/geckodriver/releases/download/v0.26.0/geckodriver-v0.26.0-linux64.tar.gz
[WDM] - Driver has been saved in cache [/home/wolf/.wdm/drivers/geckodriver/linux64/v0.26.0]
>>>

3. Web browser, which is Firefox in this case will be open.

4. Problem solved. That's it!!!

5. Additional note: If you look at the log above, geckodriver was downloaded automatically from https://github.com/mozilla/geckodriver/releases/download/v0.26.0/geckodriver-v0.26.0-linux64.tar.gz and saved to local directory which is at /home/wolf/.wdm/drivers/geckodriver/linux64/v0.26.0

6. You can also copy this binary and put it in any of your executable directory which can be get from echo $PATH command.

E.g.,

cp /home/$(whoami)/.wdm/drivers/geckodriver/linux64/v0.26.0/geckodriver /home/$(whoami)/.local/bin/

Then, let's try the sample code in https://pypi.org/project/selenium/

from selenium import webdriver

browser = webdriver.Firefox()
browser.get('http://seleniumhq.org/')

7. That's it.

import json
weather = urllib2.urlopen('url')
wjson = weather.read()
wjdata = json.loads(wjson)
print wjdata['data']['current_condition'][0]['temp_C']

What you get from the url is a json string. And your can't parse it with index directly. You should convert it to a dict by json.loads and then you can parse it with index.

Instead of using .read() to intermediately save it to memory and then read it to json, allow json to load it directly from the file:

wjdata = json.load(urllib2.urlopen('url'))

For anyone else who is seeking how to get a value from a Process using Queue:

import multiprocessing

ret = {'foo': False}

def worker(queue):
    ret = queue.get()
    ret['foo'] = True
    queue.put(ret)

if __name__ == '__main__':
    queue = multiprocessing.Queue()
    queue.put(ret)
    p = multiprocessing.Process(target=worker, args=(queue,))
    p.start()
    p.join()
    print(queue.get())  # Prints {"foo": True}

Note that in Windows or Jupyter Notebook, with multithreading you have to save this as a file and execute the file. If you do it in a command prompt you will see an error like this:

 AttributeError: Can't get attribute 'worker' on <module '__main__' (built-in)>

I had the same problem... I had to run it as a user.

        newbox.Text = newbox.Name   'Connect it to a handler, save a reference to the array & add it to the form control.
        AddHandler newbox.TextChanged, AddressOf TextBox_TextChanged
        boxes(i) = newbox
        Me.Controls.Add(newbox)
        Next
    End Sub

    Private Sub TextBox_TextChanged(sender As System.Object, e As System.EventArgs)
        'When you modify the contents of any textbox, the name of that textbox
        'and its current contents will be displayed in the title bar

        Dim box As TextBox = DirectCast(sender, TextBox)
        Me.Text = box.Name & ": " & box.Text
    End Sub
End Class

Use pyplot.text() (import matplotlib.pyplot as plt)

import matplotlib.pyplot as plt

x=[1,2,3]
y=[9,8,7]

plt.plot(x,y)
for a,b in zip(x, y): 
    plt.text(a, b, str(b))
plt.show()

My solution mayble not good

        String url = "https://www.youtube.com/watch?param=test&v=XcHJMiSy_1c&lis=test";
        int start = url.indexOf("v=")+2;
        // int start = url.indexOf("list=")+5; **5 is length of ("list=")**
        int end = url.indexOf("&", start);

        end = (end == -1 ? url.length() : end); 

        System.out.println(url.substring(start, end));
        // result: XcHJMiSy_1c

work fine with:

• https://www.youtube.com/watch?param=test&v=XcHJMiSy_1c&lis=test
• https://www.youtube.com/watch?v=XcHJMiSy_1c

Lombok does not support that also indicated by making any @Value annotated class final (as you know by using @NonFinal).

The only workaround I found is to declare all members final yourself and use the @Data annotation instead. Those subclasses need to be annotated by @EqualsAndHashCode and need an explicit all args constructor as Lombok doesn't know how to create one using the all args one of the super class:

@Data
public class A {
    private final int x;
    private final int y;
}

@Data
@EqualsAndHashCode(callSuper = true)
public class B extends A {
    private final int z;

    public B(int x, int y, int z) {
        super(x, y);
        this.z = z;
    }
}

Especially the constructors of the subclasses make the solution a little untidy for superclasses with many members, sorry.

You can use IF EXIST to check for a file:

IF EXIST "filename" (
  REM Do one thing
) ELSE (
  REM Do another thing
)

If you do not need an "else", you can do something like this:

set __myVariable=
IF EXIST "C:\folder with space\myfile.txt" set __myVariable=C:\folder with space\myfile.txt
IF EXIST "C:\some other folder with space\myfile.txt" set __myVariable=C:\some other folder with space\myfile.txt
set __myVariable=

Here's a working example of searching for a file or a folder:

REM setup

echo "some text" > filename
mkdir "foldername"

REM finds file    

IF EXIST "filename" (
  ECHO file filename exists
) ELSE (
  ECHO file filename does not exist
)

REM does not find file

IF EXIST "filename2.txt" (
  ECHO file filename2.txt exists
) ELSE (
  ECHO file filename2.txt does not exist
)

REM folders must have a trailing backslash    

REM finds folder

IF EXIST "foldername\" (
  ECHO folder foldername exists
) ELSE (
  ECHO folder foldername does not exist
)

REM does not find folder

IF EXIST "filename\" (
  ECHO folder filename exists
) ELSE (
  ECHO folder filename does not exist
)

XSD : XML Schema Definition.

XML : eXtensible Markup Language.

WSDL : Web Service Definition Language.

I am not going to answer in technical terms. I am aiming this explanation at beginners.

It is not easy to communicate between two different applications that are developed using two different technologies. For example, a company in Chicago might develop a web application using Java and another company in New York might develop an application in C# and when these two companies decided to share information then XML comes into picture. It helps to store and transport data between two different applications that are developed using different technologies. Note: It is not limited to a programming language, please do research on the information transportation between two different apps.

XSD is a schema definition. By that what I mean is, it is telling users to develop their XML in such a schema. Please see below images, and please watch closely with "load-on-startup" element and its type which is integer. In the XSD image you can see it is meant to be integer value for the "load-on-startup" and hence when user created his/her XML they passed an int value to that particular element. As a reminder, XSD is a schema and style whereas XML is a form to communicate with another application or system. One has to see XSD and create XML in such a way or else it won't communicate with another application or system which has been developed with a different technology. A company in Chicago provides a XSD template for a company in Texas to write or generate their XML in the given XSD format. If the company in Texas failed to adhere with those rules or schema mentioned in XSD then it is impossible to expect correct information from the company in Chicago. There is so much to do after the above said story, which an amateur or newbie have to know while coding for some thing like I said above. If you really want to know what happens later then it is better to sit with senior software engineers who actually developed web services. Next comes WSDL, please follow the images and try to figure out where the WSDL will fit in.

***************========Below is partial XML image ==========***************

I had to create a sample WSDL for a web service called Book. Note, it is an XSD but you have to call it WSDL (Web Service Definition Language) because it is very specific for Web Services. The above WSDL (or in other words XSD) is created for a class called Book.java and it has created a SOAP service. How the SOAP web service created it is a different topic. One has to write a Java class and before executing it create as a web service the user has to make sure Axis2 API is installed and Tomcat to host web service is in place.

As a servicer (the one who allows others (clients) to access information or data from their systems ) actually gives the client (the one who needs to use servicer information or data) complete access to data through a Web Service, because no company on the earth willing to expose their Database for outsiders. Like my company, decided to give some information about products via Web Services, hence we had to create XSD template and pass-on to few of our clients who wants to work with us. They have to write some code to make complete use of the given XSD and make Web Service calls to fetch data from servicer and convert data returned into their suitable requirement and then display or publish data or information about the product on their website. A simple example would be FLIGHT Ticket booking. An airline will let third parties to use flight data on their site for ticket sales. But again there is much more to it, it is just not letting third party flight ticket agent to sell tickets, there will be synchronize and security in place. If there is no sync then there is 100 % chances more than 1 customer might buy same flight ticket from various sources.

I am hoping experts will contribute to my answer. It is really hard for newbie or novice to understand XML, XSD and then to work on Web Services.

This example shows how to go directly to the Windows API and not link in the C Standard Library.

clazz.isAssignableFrom(Foo.class) will be true whenever the class represented by the clazz object is a superclass or superinterface of Foo.

clazz.isInstance(obj) will be true whenever the object obj is an instance of the class clazz.

That is:

clazz.isAssignableFrom(obj.getClass()) == clazz.isInstance(obj)

is always true so long as clazz and obj are nonnull.

This works perfectly for me : in git extensions :

right click on the selected commit :

reset current branch to here :

hard reset ;

It's surprising nobody else is able to give this simple answer.

The following function will parse the search string with a regular expression, cache the result and return the value of the requested variable:

window.getSearch = function(variable) {
  var parsedSearch;
  parsedSearch = window.parsedSearch || (function() {
    var match, re, ret;
    re = /\??(.*?)=([^\&]*)&?/gi;
    ret = {};
    while (match = re.exec(document.location.search)) {
      ret[match[1]] = match[2];
    }
    return window.parsedSearch = ret;
  })();
  return parsedSearch[variable];
};

You can either call it once without any parameters and work with the window.parsedSearch object, or call getSearch subsequently. I haven't fully tested this, the regular expression might still need some tweaking...

If you had caught the error, you would have seen this:

jsonString, err := json.Marshal(datas)
fmt.Println(err)

// [] json: unsupported type: map[int]main.Foo

The thing is you cannot use integers as keys in JSON; it is forbidden. Instead, you can convert these values to strings beforehand, for instance using strconv.Itoa.

You can create files in browser using Blob and URL.createObjectURL. All recent browsers support this.

You can not directly save the file you create, since that would cause massive security problems, but you can provide it as a download link for the user. You can suggest a file name via the download attribute of the link, in browsers that support the download attribute. As with any other download, the user downloading the file will have the final say on the file name though.

var textFile = null,
  makeTextFile = function (text) {
    var data = new Blob([text], {type: 'text/plain'});

    // If we are replacing a previously generated file we need to
    // manually revoke the object URL to avoid memory leaks.
    if (textFile !== null) {
      window.URL.revokeObjectURL(textFile);
    }

    textFile = window.URL.createObjectURL(data);

    // returns a URL you can use as a href
    return textFile;
  };

Here's an example that uses this technique to save arbitrary text from a textarea.

If you want to immediately initiate the download instead of requiring the user to click on a link, you can use mouse events to simulate a mouse click on the link as Lifecube's answer did. I've created an updated example that uses this technique.

  var create = document.getElementById('create'),
    textbox = document.getElementById('textbox');

  create.addEventListener('click', function () {
    var link = document.createElement('a');
    link.setAttribute('download', 'info.txt');

As you say, you don't need to request the file twice. Pass it from your controller to your directive. Assuming you use the directive inside the scope of the controller:

.controller('MyController', ['$scope', '$http', function($scope, $http) {
  $http.get('locations/locations.json').success(function(data) {
      $scope.locations = data;
  });
}

Then in your HTML (where you call upon the directive).
Note: locations is a reference to your controllers $scope.locations.

<div my-directive location-data="locations"></div>

And finally in your directive

...
scope: {
  locationData: '=locationData'
},
controller: ['$scope', function($scope){
  // And here you can access your data
  $scope.locationData
}]
...

This is just an outline to point you in the right direction, so it's incomplete and not tested.

The accepted answer didn't seem to solve the problem for me, but this did

Ensure your backgroundImage declarations are wrapped in url( and quotes so the style works correctly, no matter the file name.

ES2015 Style:

<div :style="{ backgroundImage: `url('${image}')` }"></div>

Or without ES2015:

<div :style="{ backgroundImage: 'url(\'' + image + '\')' }"></div>

I would like to note that previous answers made many assumptions about the user's knowledge. This answer attempts to answer the question at a more tutorial level.

For every invocation of Python, sys.argv is automatically a list of strings representing the arguments (as separated by spaces) on the command-line. The name comes from the C programming convention in which argv and argc represent the command line arguments.

You'll want to learn more about lists and strings as you're familiarizing yourself with Python, but in the meantime, here are a few things to know.

You can simply create a script that prints the arguments as they're represented. It also prints the number of arguments, using the len function on the list.

from __future__ import print_function
import sys
print(sys.argv, len(sys.argv))

The script requires Python 2.6 or later. If you call this script print_args.py, you can invoke it with different arguments to see what happens.

> python print_args.py
['print_args.py'] 1

> python print_args.py foo and bar
['print_args.py', 'foo', 'and', 'bar'] 4

> python print_args.py "foo and bar"
['print_args.py', 'foo and bar'] 2

> python print_args.py "foo and bar" and baz
['print_args.py', 'foo and bar', 'and', 'baz'] 4

As you can see, the command-line arguments include the script name but not the interpreter name. In this sense, Python treats the script as the executable. If you need to know the name of the executable (python in this case), you can use sys.executable.

You can see from the examples that it is possible to receive arguments that do contain spaces if the user invoked the script with arguments encapsulated in quotes, so what you get is the list of arguments as supplied by the user.

Now in your Python code, you can use this list of strings as input to your program. Since lists are indexed by zero-based integers, you can get the individual items using the list[0] syntax. For example, to get the script name:

script_name = sys.argv[0] # this will always work.

Although interesting, you rarely need to know your script name. To get the first argument after the script for a filename, you could do the following:

filename = sys.argv[1]

This is a very common usage, but note that it will fail with an IndexError if no argument was supplied.

Also, Python lets you reference a slice of a list, so to get another list of just the user-supplied arguments (but without the script name), you can do

user_args = sys.argv[1:] # get everything after the script name

Additionally, Python allows you to assign a sequence of items (including lists) to variable names. So if you expect the user to always supply two arguments, you can assign those arguments (as strings) to two variables:

user_args = sys.argv[1:]
fun, games = user_args # len(user_args) had better be 2

So, to answer your specific question, sys.argv[1] represents the first command-line argument (as a string) supplied to the script in question. It will not prompt for input, but it will fail with an IndexError if no arguments are supplied on the command-line following the script name.

My Kotlin solution is to use a static Application context:

class App : Application() {
    companion object {
        lateinit var instance: App private set
    }

    override fun onCreate() {
        super.onCreate()
        instance = this
    }
}

And the Strings class, that I use everywhere:

object Strings {
    fun get(@StringRes stringRes: Int, vararg formatArgs: Any = emptyArray()): String {
        return App.instance.getString(stringRes, *formatArgs)
    }
}

So you can have a clean way of getting resource strings

Strings.get(R.string.some_string)
Strings.get(R.string.some_string_with_arguments, "Some argument")

Please don't delete this answer, let me keep one.

I believe you want UPSERT.

"INSERT OR REPLACE" without the additional trickery in that answer will reset any fields you don't specify to NULL or other default value. (This behavior of INSERT OR REPLACE is unlike UPDATE; it's exactly like INSERT, because it actually is INSERT; however if what you wanted is UPDATE-if-exists you probably want the UPDATE semantics and will be unpleasantly surprised by the actual result.)

The trickery from the suggested UPSERT implementation is basically to use INSERT OR REPLACE, but specify all fields, using embedded SELECT clauses to retrieve the current value for fields you don't want to change.

This is identical to accepted answer (Khoth), but with the unnecessary size and i variables removed.

    int random = new Random().nextInt(myhashSet.size());
    for(Object obj : myhashSet) {
        if (random-- == 0) {
            return obj;
        }
    }

Though doing away with the two aforementioned variables, the above solution still remains random because we are relying upon random (starting at a randomly selected index) to decrement itself toward 0 over each iteration.

You can Try this

function theTest(val) {
  var answer = "";
  switch( val ) {
    case (1 || 2 || 3):
      answer = "Low";
      break;
    case (4 || 5 || 6):
      answer = "Mid";
      break;
    case (7 || 8 || 9):
      answer = "High";
      break;
    default:
      answer = "Massive or Tiny?";
  }
  return answer;
}

theTest(9);

All depends on your visualization of the array. Rows and Columns are properties of visualization (probably in your imagination) of the array, not the array itself.

It's exactly the same as asking is number "5" red or green?

I could draw it red, I could draw it greed right? Color is not an integral property of a number. In the same way representing 2D array as a grid of rows and columns is not necessary for existence of this array.

2D array has just first dimention and second dimention, everything related to visualizing those is purely your flavour.

When I have char array char[80][25], I may like to print it on console rotated so that I have 25 rows of 80 characters that fits the screen without scroll.

I'll try to provide viable example when representing 2D array as rows and columns doesn't make sense at all: Let's say I need an array of 1 000 000 000 integers. My machine has 8GB of RAM, so I have enough memory for this, but if you try executing var a = new int[1000000000], you'll most likely get OutOfMemory exception. That's because of memory fragmentation - there is no consecutive block of memory of this size. Instead you you can create 2D array 10 000 x 100 000 with your values. Logically it is 1D array, so you'd like to draw and imagine it as a single sequence of values, but due to technical implementation it is 2D.

can't you just subset the columns in either df first?

[i for i in df.columns if i not in df2.columns]

dfNew = merge(df **[i for i in df.columns if i not in df2.columns]**, df2, left_index=True, right_index=True, how='outer')

It can also be done with an IsoDateTimeConverter instance, without changing global formatting settings:

string json = JsonConvert.SerializeObject(yourObject,

First, we need to filter the XML so as to parse that change objects become array

//catch xml
$xmlElement = file_get_contents ('php://input');
//change become array
$Data = (array)simplexml_load_string($xmlElement);
//and see
print_r($Data);

You may try to_char(now()::date, 'yyyy')
If text, you've to cast your text to date to_char('2018-01-01'::date, 'yyyy')

@RobinL as mentioned in previous comments, you can use chart.series[n].setData(). First you need to make sure you’ve assigned a chart instance to the chart variable, that way it adopts all the properties and methods you need to access and manipulate the chart.

I’ve also used the second parameter of setData() and had it false, to prevent automatic rendering of the chart. This was because I have multiple data series, so I’ll rather update each of them, with render=false, and then running chart.redraw(). This multiplied performance (I’m having 10,000-100,000 data points and refreshing the data set every 50 milliseconds).

Following onto Mike Chirico's answer... if you want to append a list after the dataframe is already populated...

How about a dict comprehension:

filtered_dict = {k:v for k,v in d.iteritems() if filter_string in k}

One you see it, it should be self-explanatory, as it reads like English pretty well.

This syntax requires Python 2.7 or greater.

In Python 3, there is only dict.items(), not iteritems() so you would use:

filtered_dict = {k:v for (k,v) in d.items() if filter_string in k}

Look at my code, but be aware. I use async/await, because latest Chrome beta can read any es6 code, which gets by TypeScript with compilation. So, you must replace asyns/await by .then().

Input change handler:

/**

public psdTemplateSelectionHandler (fileInput: any){
    let FileList: FileList = fileInput.target.files;

    for (let i = 0, length = FileList.length; i < length; i++) {
        this.psdTemplates.push(FileList.item(i));
    }

    this.progressBarVisibility = true;
}

Submit handler:

public async psdTemplateUploadHandler (): Promise<any> {
    let result: any;

    if (!this.psdTemplates.length) {
        return;
    }

    this.isSubmitted = true;

    this.fileUploadService.getObserver()
        .subscribe(progress => {
            this.uploadProgress = progress;
        });

    try {
        result = await this.fileUploadService.upload(this.uploadRoute, this.psdTemplates);
    } catch (error) {
        document.write(error)
    }

    if (!result['images']) {
        return;
    }

    this.saveUploadedTemplatesData(result['images']);
    this.redirectService.redirect(this.redirectRoute);
}

FileUploadService. That service also stored uploading progress in progress$ property, and in other places, you can subscribe on it and get new value every 500ms.

The problem is not one of technical ability to send through gmail. That works for most situations. If you can't get a machine to send, it is usually due to the machine not having been authenticated with a human at the controls at least once.

The problem that most users face is that Google decides to change the outbound limits all the time. You should always add defensive code to your solution. If you start seeing errors, step off your send speed and just stop sending for a while. If you keep trying to send Google will sometimes add extra time to your delay period before you can send again.

What I have done in my current system is to send with a 1.5 second delay between each message. Then if I get any errors, stop for 5 minutes and then start again. This usually works and will allow you to send up to the limits of the account (last I checked it was 2,000 for premier customer logins per day).

If it is exactly null (as opposed to not set):

db.states.find({"cities.name": null})

(but as javierfp points out, it also matches documents that have no cities array at all, I'm assuming that they do).

If it's the case that the property is not set:

db.states.find({"cities.name": {"$exists": false}})

I've tested the above with a collection created with these two inserts:

db.states.insert({"cities": [{name: "New York"}, {name: null}]})
db.states.insert({"cities": [{name: "Austin"}, {color: "blue"}]})

The first query finds the first state, the second query finds the second. If you want to find them both with one query you can make an $or query:

db.states.find({"$or": [
  {"cities.name": null}, 
  {"cities.name": {"$exists": false}}
]})

tl;dr: JavaScript doesn't support associative arrays, therefore neither does JSON.

After all, it's JSON, not JSAAN. :)

So PHP has to convert your array into an object in order to encode into JSON.

Put your parameters in a hash table and pass them like this:

$postParams = @{username='me';moredata='qwerty'}
Invoke-WebRequest -Uri http://example.com/foobar -Method POST -Body $postParams

Download the .exe file from https://cygwin.com/install.html for cygwin (a large collection of GNU and Open Source tools which provide functionality similar to a Linux distribution on Windows).

Run the .exe file.

While installing you will get in a step to select packages. In the select package window --> change the view to "Not installed" and search for curl. click on the necessary packages to install by clicking on the "new" column for the package --> you can see the version number and then click next. ( see the image attached below)

After finishing the installation click on the cygwin to open the curl console on windows and work on curl commands.

After combining many answers and suggestion here, this is my final answer, which works well with flex, which allows us to make columns with equal height, it also checks the last index, and you don't need to repeat the inner HTML. It doesn't use clearfix:

<div ng-repeat="prod in productsFiltered=(products | filter:myInputFilter)" ng-if="$index % 3 == 0" class="row row-eq-height">
    <div ng-repeat="i in [0, 1, 2]" ng-init="product = productsFiltered[$parent.$parent.$index + i]"  ng-if="$parent.$index + i < productsFiltered.length" class="col-xs-4">
        <div class="col-xs-12">{{ product.name }}</div>
    </div>
</div>

It will output something like this:

<div class="row row-eq-height">
    <div class="col-xs-4">
        <div class="col-xs-12">
            Product Name
        </div>
    </div>
    <div class="col-xs-4">
        <div class="col-xs-12">
            Product Name
        </div>
    </div>
    <div class="col-xs-4">
        <div class="col-xs-12">
            Product Name
        </div>
    </div>
</div>
<div class="row row-eq-height">
    <div class="col-xs-4">
        <div class="col-xs-12">
            Product Name
        </div>
    </div>
    <div class="col-xs-4">
        <div class="col-xs-12">
            Product Name
        </div>
    </div>
    <div class="col-xs-4">
        <div class="col-xs-12">
            Product Name
        </div>
    </div>
</div>

Using the syntax text_element.selectionStart we can get the starting position of the selection of a text in terms of the index of the first character of the selected text in the text_element.value and in case we want to get the same of the last character in the selection we have to use text_element.selectionEnd.

Use it as follows:

<input type=text id=t1 value=abcd>
<button onclick="alert(document.getElementById('t1').selectionStart)">check position</button>

The problem is that you're trying to print an unicode character to a possibly non-unicode terminal. You need to encode it with the 'replace option before printing it, e.g. print ch.encode(sys.stdout.encoding, 'replace').

The problem is that your imgs will always bump down to the next line because of the containing div.

In order to get around this, you need to place the imgs in their own div with a width wide enough to hold all of them. Then you can use your styles as is.

So, when I set the imgs to 120px each and place them inside a

div#insideDiv{
    width:800px;
}

it all works.

Adjust width as necessary.

See http://jsfiddle.net/jasongennaro/8YfRe/

This is how I do it.

#To update your local.
git fetch --all

this will fetch everything from the remote, so when you check difference, it will compare the difference with the remote branch.

#to list all branches
git branch -a

the above command will display all the branches.

#to go to the branch you want to check difference
git checkout <branch_name>
#to check on which branch you are in, use
git branch
    (or)
git status

Now, you can check difference as follows.

git diff origin/<branch_name>

this will compare your local branch with the remote branch

With the --squash flag it looks like two parallel branches with no relation:

Sorting commits related to date looks like:

Personally, i don't like --squash option, try this trick, maybe it fits your needs, i use it for small projects:

1. git init
2. git checkout -b dev
3. Several commits in dev
4. After you did some great commits in dev(but not merged to master yet), if you do not want all commits copied to master branch, then make intentionally change something in master and (add some empty lines in README file and commit in master),
5. git merge dev It results merge conflict(empty lines in README), resolve it, commit with new message you want, and you are DONE. Here is the visual representation of it.

null commit for intentionally merge conflict, name it anything you prefer

The cmdlets in PowerShell are very nice and work reliably. Their object-orientedness appeals to me a lot since I'm a Java/C# developer, but it's not at all a complete set. Since it's object oriented, it's missed out on a lot of the text stream maturity of the POSIX tool set (awk and sed to name a few).

The best answer I've found to the dilemma of loving OO techniques and loving the maturity in the POSIX tools is to use both! One great aspect of PowerShell is that it does an excellent job piping objects to standard streams. PowerShell by default uses an object pipeline to transport its objects around. These aren't the standard streams (standard out, standard error, and standard in). When PowerShell needs to pass output to a standard process that doesn't have an object pipeline, it first converts the objects to a text stream. Since it does this so well, PowerShell makes an excellent place to host POSIX tools!

The best POSIX tool set is GnuWin32. It does take more than 5 seconds to install, but it's worth the trouble, and as far as I can tell, it doesn't modify your system (registry, c:\windows\* folders, etc.) except copying files to the directories you specify. This is extra nice because if you put the tools in a shared directory, many people can access them concurrently.

GnuWin32 Installation Instructions

Download and execute the exe (it's from the SourceForge site) pointing it to a suitable directory (I'll be using C:\bin). It will create a GetGnuWin32 directory there in which you will run download.bat, then install.bat (without parameters), after which, there will be a C:\bin\GetGnuWin32\gnuwin32\bin directory that is the most useful folder that has ever existed on a Windows machine. Add that directory to your path, and you're ready to go.

In order to get the popup exactly centered, it's a simple matter of applying a negative top margin of half the div height, and a negative left margin of half the div width. For this example, like so:

.div {
    position: fixed;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    width: 50%;
}

TASKLIST does not set errorlevel.

echo off
tasklist /fi "imagename eq notepad.exe" |find ":" > nul
if errorlevel 1 taskkill /f /im "notepad.exe"
exit

should do the job, since ":" should appear in TASKLIST output only if the task is NOT found, hence FIND will set the errorlevel to 0 for not found and 1 for found

Nevertheless,

taskkill /f /im "notepad.exe"

will kill a notepad task if it exists - it can do nothing if no notepad task exists, so you don't really need to test - unless there's something else you want to do...like perhaps

echo off
tasklist /fi "imagename eq notepad.exe" |find ":" > nul
if errorlevel 1 taskkill /f /im "notepad.exe"&exit

which would appear to do as you ask - kill the notepad process if it exists, then exit - otherwise continue with the batch

The same thing happened to me with the '–' character (long minus sign).
I used this simple replace so resolve it:

htmlText = htmlText.Replace('–', '-');

            MethodResult = Architecture;

        }
        catch //(Exception ex)
        {
            //ex.HandleException();
        }
        return MethodResult;
    }

Use it like so:

string Architecture = "This is a " + GetBit() + "bit machine";

I didn't see how to add parameters to the method call, it took me a while to find it, so I add it here. How to pass parameters in (to the javascript function), use "arguments[0]" as the parameter place and then set the parameter as input parameter in the executeScript function.

    driver.executeScript("function(arguments[0]);","parameter to send in");

maybe you need this.

>>> x = np.array([11,22])
>>> y = np.array([18,7,6])
>>> z = np.array([1,3,5])
>>> np.concatenate((x,y,z))
array([11, 22, 18,  7,  6,  1,  3,  5])

Dirk's answer here is everything you need. Here's a minimal reproducible example.

I made two files: exmpl.bat and exmpl.R.

• exmpl.bat:

  set R_Script="C:\Program Files\R-3.0.2\bin\RScript.exe"
  %R_Script% exmpl.R 2010-01-28 example 100 > exmpl.batch 2>&1
  

  Alternatively, using Rterm.exe:

  set R_TERM="C:\Program Files\R-3.0.2\bin\i386\Rterm.exe"
  %R_TERM% --no-restore --no-save --args 2010-01-28 example 100 < exmpl.R > exmpl.batch 2>&1
  

• exmpl.R:

  options(echo=TRUE) # if you want see commands in output file
  args <- commandArgs(trailingOnly = TRUE)
  print(args)
  # trailingOnly=TRUE means that only your arguments are returned, check:
  # print(commandArgs(trailingOnly=FALSE))
  
  start_date <- as.Date(args[1])
  name <- args[2]
  n <- as.integer(args[3])
  rm(args)
  
  # Some computations:
  x <- rnorm(n)
  png(paste(name,".png",sep=""))
  plot(start_date+(1L:n), x)
  dev.off()
  
  summary(x)
  

Save both files in the same directory and start exmpl.bat. In the result you'll get:

• example.png with some plot
• exmpl.batch with all that was done

You could also add an environment variable %R_Script%:

"C:\Program Files\R-3.0.2\bin\RScript.exe"

and use it in your batch scripts as %R_Script% <filename.r> <arguments>

Differences between RScript and Rterm:

• Rscript has simpler syntax
• Rscript automatically chooses architecture on x64 (see R Installation and Administration, 2.6 Sub-architectures for details)
• Rscript needs options(echo=TRUE) in the .R file if you want to write the commands to the output file

You can convert a string to a DATE using the TO_DATE function, then reformat the date as another string using TO_CHAR, i.e.:

SELECT TO_CHAR(
         TO_DATE('15/August/2009,4:30 PM'
                ,'DD/Month/YYYY,HH:MI AM')
       ,'DD-MM-YYYY')
FROM DUAL;

15-08-2009

For example, if your table name is MYTABLE and the varchar2 column is MYDATESTRING:

SELECT TO_CHAR(
         TO_DATE(MYDATESTRING
                ,'DD/Month/YYYY,HH:MI AM')
       ,'DD-MM-YYYY')
FROM MYTABLE;

Another reply to your questions (assuming you are on master and already did "git fetch origin" to make you repo aware about remote changes):

1) Commits on remote branch since when local branch was created:

git diff HEAD...origin/master

2) I assume by "working copy" you mean your local branch with some local commits that are not yet on remote. To see the differences of what you have on your local branch but that does not exist on remote branch run:

git diff origin/master...HEAD

3) See the answer by dbyrne.

It defines an XML Namespace.

In your example, the Namespace Prefix is "android" and the Namespace URI is "http://schemas.android.com/apk/res/android"

In the document, you see elements like: <android:foo />

Think of the namespace prefix as a variable with a short name alias for the full namespace URI. It is the equivalent of writing <http://schemas.android.com/apk/res/android:foo /> with regards to what it "means" when an XML parser reads the document.

NOTE: You cannot actually use the full namespace URI in place of the namespace prefix in an XML instance document.

Check out this tutorial on namespaces: http://www.sitepoint.com/xml-namespaces-explained/

If you are using Twig templates for Symfony, you can use the classic {{object.date_attribute.format('d/m/Y')}} to obtain the desired formatted date.

The best way to get rid of dead container processes is to restart your docker service. I was unable to remove a container as it was stuck in restarting status, I just restarted the docker service and it worked for me.

using row major example:

A(i,j) = a[i + j*ld]; // where ld is the leading dimension
                      // (commonly same as array dimension in i)

// matrix like notation using preprocessor hack, allows to hide indexing
#define A(i,j) A[(i) + (j)*ld]

double *A = ...;
size_t ld = ...;
A(i,j) = ...;
... = A(j,i);

I'd recommend serialization,

public class Person
{
      public  string FirstName;
      public  string MI;
      public  string LastName;
}

static void Serialize()
{
      clsPerson p = new Person();
      p.FirstName = "Jeff";
      p.MI = "A";
      p.LastName = "Price";
      System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(p.GetType());
      x.Serialize(System.Console.Out, p);
      System.Console.WriteLine();
      System.Console.WriteLine(" --- Press any key to continue --- ");
      System.Console.ReadKey();
}

You can further control serialization with attributes.
But if it is simple, you could use XmlDocument:

using System;
using System.Xml;

public class GenerateXml {
    private static void Main() {
        XmlDocument doc = new XmlDocument();
        XmlNode docNode = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
        doc.AppendChild(docNode);

        XmlNode productsNode = doc.CreateElement("products");
        doc.AppendChild(productsNode);

        XmlNode productNode = doc.CreateElement("product");
        XmlAttribute productAttribute = doc.CreateAttribute("id");
        productAttribute.Value = "01";
        productNode.Attributes.Append(productAttribute);
        productsNode.AppendChild(productNode);

        XmlNode nameNode = doc.CreateElement("Name");
        nameNode.AppendChild(doc.CreateTextNode("Java"));
        productNode.AppendChild(nameNode);
        XmlNode priceNode = doc.CreateElement("Price");
        priceNode.AppendChild(doc.CreateTextNode("Free"));
        productNode.AppendChild(priceNode);

        // Create and add another product node.
        productNode = doc.CreateElement("product");
        productAttribute = doc.CreateAttribute("id");
        productAttribute.Value = "02";
        productNode.Attributes.Append(productAttribute);
        productsNode.AppendChild(productNode);
        nameNode = doc.CreateElement("Name");
        nameNode.AppendChild(doc.CreateTextNode("C#"));
        productNode.AppendChild(nameNode);
        priceNode = doc.CreateElement("Price");
        priceNode.AppendChild(doc.CreateTextNode("Free"));
        productNode.AppendChild(priceNode);

        doc.Save(Console.Out);
    }
}

And if it needs to be fast, use XmlWriter:

public static void WriteXML()
{
    // Create an XmlWriterSettings object with the correct options.
    System.Xml.XmlWriterSettings settings = new System.Xml.XmlWriterSettings();
    settings.Indent = true;
    settings.IndentChars = "    "; //  "\t";
    settings.OmitXmlDeclaration = false;
    settings.Encoding = System.Text.Encoding.UTF8;

    using (System.Xml.XmlWriter writer = System.Xml.XmlWriter.Create("data.xml", settings))
    {

        writer.WriteStartDocument();
        writer.WriteStartElement("books");

        for (int i = 0; i < 100; ++i)
        {
            writer.WriteStartElement("book");
            writer.WriteElementString("item", "Book "+ (i+1).ToString());
            writer.WriteEndElement();
        }

        writer.WriteEndElement();

        writer.Flush();
        writer.Close();
    } // End Using writer 

}

And btw, the fastest way to read XML is XmlReader:

public static void ReadXML()
{
    using (System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create("http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml"))
    {
        while (xmlReader.Read())
        {
            if ((xmlReader.NodeType == System.Xml.XmlNodeType.Element) && (xmlReader.Name == "Cube"))
            {
                if (xmlReader.HasAttributes)
                    System.Console.WriteLine(xmlReader.GetAttribute("currency") + ": " + xmlReader.GetAttribute("rate"));
            }

        } // Whend 

    } // End Using xmlReader

    System.Console.ReadKey();
}

And the most convenient way to read XML is to just deserialize the XML into a class.
This also works for creating the serialization classes, btw.
You can generate the class from XML with Xml2CSharp:

Remove some of your textarea class like

<textarea name="Address" rows="3" class="input-text full-width" placeholder="Your Address" ></textarea>

To

<textarea name="Address" rows="3" class="full-width" placeholder="Your Address" ></textarea>

It's dependent on your template (Purchased Template). The developer has included some JavaScript to get the value from correct object on UI, but class like input-text just finds only $('input[type=text]'), that's why.

• process.cwd() returns directory where command has been executed (not directory of the node package) if it's has not been changed by 'process.chdir' inside of application.
• __filename returns absolute path to file where it is placed.
• __dirname returns absolute path to directory of __filename.

If you need to load files from your module directory you need to use relative paths.

require('../lib/test');

instead of

var lib  = path.join(path.dirname(fs.realpathSync(__filename)), '../lib');

require(lib + '/test');

It's always relative to file where it called from and don't depend on current work dir.

Try this

> dt.columns.Add("ColumnName", typeof(Give the type you want));
> dt.Rows[give the row no like  or  or any no]["Column name in which you want to add data"] = Value;

I ran into the same error.

NAME         READY   STATUS             RESTARTS   AGE
pod/webapp   0/1     CrashLoopBackOff   5          47h

My problem was that I was trying to run two different pods with the same metadata name.

kind: Pod metadata: name: webapp labels: ...

To find all the names of your pods run: kubectl get pods

NAME         READY   STATUS    RESTARTS   AGE
webapp       1/1     Running   15         47h

then I changed the conflicting pod name and everything worked just fine.

NAME                 READY   STATUS    RESTARTS   AGE
webapp               1/1     Running   17         2d
webapp-release-0-5   1/1     Running   0          13m

Regarding apply vs map:

pool.apply(f, args): f is only executed in ONE of the workers of the pool. So ONE of the processes in the pool will run f(args).

pool.map(f, iterable): This method chops the iterable into a number of chunks which it submits to the process pool as separate tasks. So you take advantage of all the processes in the pool.

To take input " long int " and output " long int " in C is :

long int n;
scanf("%ld", &n);
printf("%ld", n);

To take input " long long int " and output " long long int " in C is :

long long int n;
scanf("%lld", &n);
printf("%lld", n);

Hope you've cleared..

As it's not specified if you mean the system's current date or the date held in a variable, I'll answer for latter with an example.

<?php
$dateAsString = "Wed, 11 Apr 2018 19:00:00 -0500";

// This converts it to a unix timestamp so that the date() function can work with it.
$dateAsUnixTimestamp = strtotime($dateAsString);

// Output it month is various formats according to http://php.net/date

echo date('M',$dateAsUnixTimestamp);
// Will output Apr

echo date('n',$dateAsUnixTimestamp);
// Will output 4

echo date('m',$dateAsUnixTimestamp);
// Will output 04
?>

- Each time you append or do any modification with it, it creates a new String object.

- So use append() method of StringBuilder(If thread safety is not important), else use StringBuffer(If thread safety is important.), that will be efficient way to do it.

There is nothing like session container , so you can set it as null

but rather you can set individual session element as null or ""

like Session["userid"] = null;

L = ['L','O','L']
makeitastring = ''.join(map(str, L))

All you need to do is edit the iframe code that facebook gives you and change the width to 47 (you need to change it in 2 places). Seems to work perfectly for me so far.

No one seems to have mentioned about the negative infinity explicitly, so I think I should add it.

For negative infinity:

-math.inf

For positive infinity (just for the sake of completeness):

math.inf

str="abcdef"

str.index('c') #=> 2 #String matching approach
str=~/c/ #=> 2 #Regexp approach 
$~ #=> #<MatchData "c">

Hope it helps. :)

• Failed validation: 403 Forbidden ("The server understood the request, but is refusing to fulfill it"). Contrary to popular opinion, RFC2616 doesn't say "403 is only intended for failed authentication", but "403: I know what you want, but I won't do that". That condition may or may not be due to authentication.
• Trying to add a duplicate: 409 Conflict ("The request could not be completed due to a conflict with the current state of the resource.")

You should definitely give a more detailed explanation in the response headers and/or body (e.g. with a custom header - X-Status-Reason: Validation failed).

Try this- Close the project then open it. It links with svn automatically,if project was checked out from valid svn path.

I'm hardly a caching expert, but Mark Nottingham is. Here are his caching docs. He also has excellent links in the References section.

Based on my reading of those docs, it looks like max-age=0 could allow the cache to send a cached response to requests that came in at the "same time" where "same time" means close enough together they look simultaneous to the cache, but no-cache would not.

Nice answer you can find in book Learning Cocoa with Objective-C (ISBN: 978-1-491-90139-7)

Modules are a new means of including and linking files and libraries into your projects. To understand how modules work and what benefits they have, it is important to look back into the history of Objective-C and the #import statement Whenever you want to include a file for use, you will generally have some code that looks like this:

#import "someFile.h"

Or in the case of frameworks:

#import <SomeLibrary/SomeFile.h>

Because Objective-C is a superset of the C programming language, the #import state- ment is a minor refinement upon C’s #include statement. The #include statement is very simple; it copies everything it finds in the included file into your code during compilation. This can sometimes cause significant problems. For example, imagine you have two header files: SomeFileA.h and SomeFileB.h; SomeFileA.h includes SomeFileB.h, and SomeFileB.h includes SomeFileA.h. This creates a loop, and can confuse the coimpiler. To deal with this, C programmers have to write guards against this type of event from occurring.

When using #import, you don’t need to worry about this issue or write header guards to avoid it. However, #import is still just a glorified copy-and-paste action, causing slow compilation time among a host of other smaller but still very dangerous issues (such as an included file overriding something you have declared elsewhere in your own code.)

Modules are an attempt to get around this. They are no longer a copy-and-paste into source code, but a serialised representation of the included files that can be imported into your source code only when and where they’re needed. By using modules, code will generally compile faster, and be safer than using either #include or #import.

Returning to the previous example of importing a framework:

#import <SomeLibrary/SomeFile.h>

To import this library as a module, the code would be changed to:

@import SomeLibrary;

This has the added bonus of Xcode linking the SomeLibrary framework into the project automatically. Modules also allow you to only include the components you really need into your project. For example, if you want to use the AwesomeObject component in the AwesomeLibrary framework, normally you would have to import everything just to use the one piece. However, using modules, you can just import the specific object you want to use:

@import AwesomeLibrary.AwesomeObject;

For all new projects made in Xcode 5, modules are enabled by default. If you want to use modules in older projects (and you really should) they will have to be enabled in the project’s build settings. Once you do that, you can use both #import and @import statements in your code together without any concern.

In ur script page...

    $('.a-middle').css('margin-top', function () {
        return ($(window).height() - $(this).height()) / 2
    });

Use a-middle class in the Div...

   <div class="a-middle">

There's a threshold because the meaning of the digit has gone from integer to non-integer. To represent 61, you have 6*10^1 + 1*10^0; 10^1 and 10^0 are both integers. 6.1 is 6*10^0 + 1*10^-1, but 10^-1 is 1/10, which is definitely not an integer. That's how you end up in Inexactville.

I just spent the better part of 3 days wrestling with this. I'm working on an application that loads other applications into itself while maintaining a fixed header and a fixed footer. Here's what I've come up with. (I also used EasyXDM, with success, but pulled it out later to use this solution.)

Make sure to run this code AFTER the <iframe> exists in the DOM. Put it into the page that pulls in the iframe (the parent).

// get the iframe
var theFrame = $("#myIframe");
// set its height to the height of the window minus the combined height of fixed header and footer
theFrame.height(Number($(window).height()) - 80);

function resizeIframe() {
    theFrame.height(Number($(window).height()) - 80);
}

// setup a resize method to fire off resizeIframe.
// use timeout to filter out unnecessary firing.
var TO = false;
$(window).resize(function() {
    if (TO !== false) clearTimeout(TO);
    TO = setTimeout(resizeIframe, 500); //500 is time in miliseconds
});

This would require a sort (O(n log n)) but is very simple and flexible. Another advantage is being able to use it with LINQ to SQL:

var maxObject = list.OrderByDescending(item => item.Height).First();

Note that this has the advantage of enumerating the list sequence just once. While it might not matter if list is a List<T> that doesn't change in the meantime, it could matter for arbitrary IEnumerable<T> objects. Nothing guarantees that the sequence doesn't change in different enumerations so methods that are doing it multiple times can be dangerous (and inefficient, depending on the nature of the sequence). However, it's still a less than ideal solution for large sequences. I suggest writing your own MaxObject extension manually if you have a large set of items to be able to do it in one pass without sorting and other stuff whatsoever (O(n)):

static class EnumerableExtensions {
    public static T MaxObject<T,U>(this IEnumerable<T> source, Func<T,U> selector)
      where U : IComparable<U> {
       if (source == null) throw new ArgumentNullException("source");
       bool first = true;
       T maxObj = default(T);
       U maxKey = default(U);
       foreach (var item in source) {
           if (first) {
                maxObj = item;
                maxKey = selector(maxObj);
                first = false;
           } else {
                U currentKey = selector(item);
                if (currentKey.CompareTo(maxKey) > 0) {
                    maxKey = currentKey;
                    maxObj = item;
                }
           }
       }
       if (first) throw new InvalidOperationException("Sequence is empty.");
       return maxObj;
    }
}

and use it with:

var maxObject = list.MaxObject(item => item.Height);
