unfortunately, with "mvim -v", ALT plus arrow windows still does not work. I have not found any way to enable it :-(

I have this setup in my Ubuntu .vimrc. I don't see any swap files in my project files.

• Place your cursor at the end of the text.
• Press SHIFT and ->. The cursor will move to the next line.
• Press CTRL-F and type , in "Replace with:" and press ENTER.

You will need to put a quote at the beginning of your first text and the end of your last.

Just to note,

MixEdit is not completely free.

"This software is currently not licensed to any user and is running in evaluation mode. MIXEDIT may be downloaded and evaluated for free, however a license must be purchased for continued use."

Upon installation and use, a popup redirects to webpage - similar to SublimeText's unlicensed software pop-up message.

You should try TextPad, it can read a file of that size.

It's free to evaluate (you can evaluate indefinitely)

In addition to the points from prior answers, it's worth clarifying the differences between these two products from the perspective of choices made in their development.

Sublime is binary compiled for the platform. Its core is written in C/C++ and a number of its features are implemented in Python, which is also the language used for extending it. Atom is written in Node.js/Coffeescript and runs under webkit, with Coffeescript being the extension language. Though similar in UI and UX, Sublime performs significantly better than Atom especially in "heavy lifting" like working with large files, complex SnR or plugins that do heavy processing on files/buffers. Though I expect improvements in Atom as it matures, design & platform choices limit performance.

The "closed" part of Sublime includes the API and UI. Apart from skins/themes and colourisers, the API currently makes it difficult to modify other aspects of the UI. For example, Sublime plugins can't interact with the sidebar, control or draw on the editing area (except in some limited ways eg. in the gutter) or manipulate the statusbar beyond basic text. Atom's "closed" part is unknown at the moment, but I get the sense it's smaller. Atom has a richer API (though poorly documented at present) with the design goal of allowing greater control of its UI. Being closely coupled with webkit offers numerous capabilities for UI feature enhancements not presently possible with Sublime. However, Sublime's extensions perform closer to native, so those that perform compute-intensive, highly repetitive or complex text manipulations in large buffers are feasible in Sublime.

Since more of Atom will be open, Github open-sourced Atom on May 6th. As a result it's likely that support and pace of development will be rapid. By contrast, Sublime's development has slowed significantly of late - but it's not dead. In particular there are a number of bugs, many quite trivial, that haven't been fixed by the developer. None are showstopping imo, but if you want something in rapid development with regular bugfixing and enhancements, Sublime will frustrate. That said, installable Atom packages for Windows and Linux are yet to be released and activity on the codebase seems to have cooled in the weeks before and since the announcement, according to Github's stats.

In terms of IDE functions, from a webdev perspective Atom will allow extensions to the point of approaching products like Webstorm, though none have appeared yet. It remains to be seen how Atom will perform with such "heavy" extensions, since the editor natively feels sluggish. Due to restrictions in the API and lack of underlying webkit, Sublime won't allow this level of UI customisation although the developer may extend the API to support such features in future. Again, Sublime's underlying performance allows for things that involve computational grunt; ST3's symbol indexing being an example that performs well even with big projects. And though Atom's UI is certainly modelled upon Sublime, some refinements are noticeably missing, such as Sublime's learning panels and tab-complete popups which weight the defaults in accordance with those you most use.

I see these products as complementary. The fact that they share similar visuals and keystrokes just adds to the fact. There will be situations where the use of either has advantages. Presently, Sublime is a mature product with feature parity across all three platforms, and a rich set of plugins. Atom is the new kid whose features will rapidly grow; it doesn't feel production ready just yet and there are concerns in the area of performance.

[Update/Edit: May 18, 2015]

A note about improvements to these two editors since the time of writing the above.

In addition to bugfixes and improvements to its core, Atom has experienced a rapid growth in third-party extensions, with autocomplete-plus becoming part of the standard Atom distribution. Extension quality varies widely and a particular irritation is the frequency by which unstable third party packages can crash the editor. Within the last year, Atom has moved to using React by way of shifting reflow/repaint activity to the GPU for performance reasons, significantly improving the responsiveness of the UI for typical editing actions (scrolling, cursor movement etc.). While this has markedly improved the feel of the editor, it still feels cumbersome for CPU intensive tasks as described above, and is still slow in startup. Apart from performance improvements, Atom feels significantly more stable across the board.

Development of Sublime has picked up again since Jan 2015, with bugfixes, some minor new features (tooltip API, build system improvements) and a major development in the form of a new yaml-based .sublime-syntax definition (to eventually replace the old xml .tmLanguage). Together with a custom regex engine which replaces Onigurama, the new system offers more potential for precise regex matching, is significantly faster (up to 4x) and can perform multiple matches in parallel. Apart from colouring syntax, Sublime uses these components for symbol indexing (goto definition etc.) and other language-aware features. In addition to further speeding up Sublime, particularly for large files, this feature should open up the potential for performant language-specific features such as code-refactoring etc.. Further 'big developments' are promised, though the author remains, as ever, tight lipped about them.

Kinesics Text Editor.

It's super fast and handles large text files, though minimal in features. There's a GUI version and console version (k.exe) included. Should work the same on linux.

Example: In my test it took 7 seconds to open a 500mb disk image.

It's really tough to handle a 4G file as such. I used to handle larger text files, but I never used to load them in to my editor. I mostly used UltraEdit in my previous company, now I use Notepad++, but I would get just those parts which i needed to edit. (Most of the cases, the files never needed an edit).

Why do u want to load such a big file in to an editor? When I handled files of these size, I used GNU Core Utils. The most common operations i performed on those files were head ( to get the top 250k lines etc ), tail, split, sort, shuf, uniq etc. It's really powerful.

There's a lot of things you can do with GNU Core Utils. I would definitely recommend those, instead of a new editor.

Double check your text with the Hex Editor Plug-in. In your case there may have been some control characters which have crept into your text. Usually you'll look at the white-space, and it will say 32 32 32 32, or for Unicode 32 00 32 00 32 00 32 00. You may find the problem this way, providing there isn't masses of code.

Download the Hex Plugin from here; http://sourceforge.net/projects/npp-plugins/files/Hex%20Editor/

You can run specific lines of script by highlighting them and clicking shift + ctrl + b

You can also use command line by going to the root folder and writing: $ node nameOfFile.js

Do it the vi way.

To delete 5 lines press: 5dd ( 5 delete )

To select ( actually copy them to the clipboard ) you type: 10yy

It is a bit hard to grasp, but very handy to learn when using those remote terminals

Be aware of the learning curves for some editors:

_{(source: calver at unix.rulez.org)}

You need the textFX plugin. Then, just follow these instructions:

Paste the text into Notepad++ (CTRL+V). ...
Mark all the text (CTRL+A). ...
Click TextFX ? Click TextFX Tools ? Click Sort lines case insensitive (at column)
Duplicates and blank lines have been removed and the data has been sorted alphabetically.

Personally, I would use sort -i -u source >dest instead of notepad++

You're in replace mode. Press the Insert key on your keyboard to switch back to insert mode. Many applications that handle text have this in common.

Free read-only viewers:

• Large Text File Viewer (Windows) – Fully customizable theming (colors, fonts, word wrap, tab size). Supports horizontal and vertical split view. Also support file following and regex search. Very fast, simple, and has small executable size.
• klogg (Windows, macOS, Linux) – A maintained fork of glogg, its main feature is regular expression search. It can also watch files, allows the user to mark lines, and has serious optimizations built in. But from a UI standpoint, it's ugly and clunky.
• LogExpert (Windows) – "A GUI replacement for tail." It's really a log file analyzer, not a large file viewer, and in one test it required 10 seconds and 700 MB of RAM to load a 250 MB file. But its killer features are the columnizer (parse logs that are in CSV, JSONL, etc. and display in a spreadsheet format) and the highlighter (show lines with certain words in certain colors). Also supports file following, tabs, multifiles, bookmarks, search, plugins, and external tools.
• Lister (Windows) – Very small and minimalist. It's one executable, barely 500 KB, but it still supports searching (with regexes), printing, a hex editor mode, and settings.
• loxx (Windows) – Supports file following, highlighting, line numbers, huge files, regex, multiple files and views, and much more. The free version can not: process regex, filter files, synchronize timestamps, and save changed files.

Free editors:

• Your regular editor or IDE. Modern editors can handle surprisingly large files. In particular, Vim (Windows, macOS, Linux), Emacs (Windows, macOS, Linux), Notepad++ (Windows), Sublime Text (Windows, macOS, Linux), and VS Code (Windows, macOS, Linux) support large (~4 GB) files, assuming you have the RAM.
• Large File Editor (Windows) – Opens and edits TB+ files, supports Unicode, uses little memory, has XML-specific features, and includes a binary mode.
• GigaEdit (Windows) – Supports searching, character statistics, and font customization. But it's buggy – with large files, it only allows overwriting characters, not inserting them; it doesn't respect LF as a line terminator, only CRLF; and it's slow.

Builtin programs (no installation required):

• less (macOS, Linux) – The traditional Unix command-line pager tool. Lets you view text files of practically any size. Can be installed on Windows, too.
• Notepad (Windows) – Decent with large files, especially with word wrap turned off.
• MORE (Windows) – This refers to the Windows MORE, not the Unix more. A console program that allows you to view a file, one screen at a time.

Web viewers:

• readfileonline.com – Another HTML5 large file viewer. Supports search.

Paid editors:

• 010 Editor (Windows, macOS, Linux) – Opens giant (as large as 50 GB) files.
• SlickEdit (Windows, macOS, Linux) – Opens large files.
• UltraEdit (Windows, macOS, Linux) – Opens files of more than 6 GB, but the configuration must be changed for this to be practical: Menu » Advanced » Configuration » File Handling » Temporary Files » Open file without temp file...
• EmEditor (Windows) – Handles very large text files nicely (officially up to 248 GB, but as much as 900 GB according to one report).
• BssEditor (Windows) – Handles large files and very long lines. Don’t require an installation. Free for non commercial use.

Ctrl-v ................ start visual block selection

You can turn on syntax highlighting based on the contents of the file.

For example, my Makefiles regardless of their extension the first line as follows:

#-*-Makefile-*- vim:syntax=make

This is typical practice for other editors such as vim.

However, for this to work you need to modify the Makefile.tmLanguage file.

1. Find the file (for Sublime Text 3 in Ubuntu) at:

   /opt/sublime_text/Packages/Makefile.sublime-package
   

Note, that is really a zip file. Copy it, rename with .zip at the end, and extract the Makefile.tmLanguage file from it.

2. Edit the new Makefile.tmLanguage by adding the "firstLineMatch" key and string after the "fileTypes" section. In the example below, the last two lines are new (should be added by you). The <string> section holds the regular expression, that will enable syntax highlighting for the files that match the first line. This expression recognizes two patterns: "-*-Makefile-*-" and "vim:syntax=make".

   ...
   <key>fileTypes</key>
   <array>
       <string>GNUmakefile</string>
       <string>makefile</string>
       <string>Makefile</string>
       <string>OCamlMakefile</string>
       <string>make</string>
   </array>
   
   <key>firstLineMatch</key>
   <string>^#\s*-\*-Makefile-\*-|^#.*\s*vim:syntax=make</string>
   

3. Place the modified Makefile.tmLanguage in the User settings directory:

   ~/.config/sublime-text-3/Packages/User/Makefile.tmLanguage
   

All the files matching the first line rule should turn the syntax highlighting on when opened.

in Notepad++v6.1.8 (Unicode) it works after removing the QuickText plugin.

• Press Alt + Shift + A
• Observe that the screen zooms out
• Make selection using the mouse
• Press Alt + Shift + A to go back to the old mode.

Try Notepad++. It shows all characters. In addition, you could use the utility dos2unix to convert a file to all /n, or "conv" (same link) to convert either way.

typing "code" in dos command prompt worked for me

git config core.editor "\"C:\Program Files (x86)\Notepad++\notepad++.exe\""

Here's the workflow I use all the time, using the keyboard only

1. Ctrl/Cmd + A Select All
2. Ctrl/Cmd + Shift + L Split into Lines
3. ' Surround every line with quotes

Note that this doesn't work if there are blank lines in the selection.

For Sublime Text 3:

defaults write com.apple.LaunchServices LSHandlers -array-add '{LSHandlerContentType=public.plain-text;LSHandlerRoleAll=com.sublimetext.3;}'

See Set TextMate as the default text editor on Mac OS X for details.

Add the following line in your Dockerfile then rebuild the docker image.

RUN apt-get update && apt-get install -y vim

You can view break lines using gedit editor.

First, if you don't have installed:

sudo apt-get install gedit

Now, install gedit plugins:

sudo apt-get install gedit-plugins

and select Draw Spaces plugin, enter on Preferences, and chose Draw new lines

Using VSCode you can install Line endings extension.

Sublime Text 3 has a plugin called RawLineEdit that will display line endings and allow the insertion of arbitrary line-ending type

shift + ctrl + p and start type the name of the plugin, and toggle to show line ending.

Just access the element and append it to the value.

<input
     type="button" 
     onclick="document.getElementById('myTextArea').value += '•'" 
     value="Add •">

See a live demo.

For the sake of keeping things simple, I haven't written unobtrusive JS. For a production system you should.

Also it needs to be a UTF8 character.

Browsers generally submit forms using the encoding they received the page in. Serve your page as UTF-8 if you want UTF-8 data submitted back.

Try this way. It got worked for me

1. Open Notepad++ then copy your content
2. Press ctrl + h
3. Find what is should be ,(comma) or any character that you want to replace
4. Replace with should be \n
5. Select Search Mode -> Extended (\n, \r, \t, \0)
6. Then Click on Replace All

It's probably easiest to create your query object directly as:

  Test.find({
      $and: [
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ]
  }, function (err, results) {
      ...
  }

But you can also use the Query#and helper that's available in recent 3.x Mongoose releases:

  Test.find()
      .and([
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ])
      .exec(function (err, results) {
          ...
      });

You can use a stubbing library like sinon to mock your service. You can then return $q.when() as your promise. If your scope object's value comes from the promise result, you will need to call scope.$root.$digest().

var scope, controller, datacontextMock, customer;
  beforeEach(function () {
        module('app');
        inject(function ($rootScope, $controller,common, datacontext) {
            scope = $rootScope.$new();
            var $q = common.$q;
            datacontextMock = sinon.stub(datacontext);
            customer = {id:1};
           datacontextMock.customer.returns($q.when(customer));

            controller = $controller('Index', { $scope: scope });

        })
    });


    it('customer id to be 1.', function () {


            scope.$root.$digest();
            expect(controller.customer.id).toBe(1);


    });

In case none of the above works for you:

I've done quite a few Postgres installations, but was flummoxed today on a RedHat 6.5 system (installing Postgres 9.3). My typical hba.conf configuration that Aron shows above didn't work. It turned out that my system was using IPV6, and ignoring the IPV4 configuration. Adding the line:

host    all             all             ::1/128                 password

allowed me to login successfully.

Here is the best, simple, short and clean way to "rename" the text of an input with file type and without JQuery, with pure HTML and javascript:

<input id='browse' type='file' style='width:0px'>
<button id='browser' onclick='browse.click()'>
    *The text you want*
</button>

Of all of the answers here, I think they either don't work, or they're a bit of a hack (casting back to NSString). It's very likely that the correct answer to this has changed with the different beta releases.

Here is what I use:

let string: String = "hello Swift"
if string.rangeOfString("Swift") != nil
{
    println("exists")
}

The "!= nil" became required with Beta 5.

If each part have the same lines number, for example 22, here my solution:
split --numeric-suffixes=2 --additional-suffix=.txt -l 22 file.txt file
and you obtain file2.txt with the first 22 lines, file3.txt the 22 next line…

Thank @hamruta-takawale, @dror-s and @stackoverflowuser2010

solution is easy:

replace

 mask = (50  < df['heart rate'] < 101 &
            140 < df['systolic blood pressure'] < 160 &
            90  < df['dyastolic blood pressure'] < 100 &
            35  < df['temperature'] < 39 &
            11  < df['respiratory rate'] < 19 &
            95  < df['pulse oximetry'] < 100
            , "excellent", "critical")

by

mask = ((50  < df['heart rate'] < 101) &
        (140 < df['systolic blood pressure'] < 160) &
        (90  < df['dyastolic blood pressure'] < 100) &
        (35  < df['temperature'] < 39) &
        (11  < df['respiratory rate'] < 19) &
        (95  < df['pulse oximetry'] < 100)
        , "excellent", "critical")

If you want your container ports to bind on your ipv4 address, just :

• find the settings file
  • /etc/sysconfig/docker-network on RedHat alike
  • /etc/default/docker-network on Debian ans alike
• edit the network settings
  • add DOCKER_NETWORK_OPTIONS=-ip=xx.xx.xx.xx
  • xx.xx.xx.xx being your real ipv4 (and not 0.0.0.0)
• restart docker deamon

works for me on docker 1.9.1

Let me suggest you an easier approach,

Instead of divind into GIT's deep consepts and bothering with the editor's crab, you could do the following;

Lets suppose you created a branch named bug1 from master. Made 2 commits to bug1. You only modified 2 files with these changes.

Copy these two files into a text editor. Checkout master. Paste the files. Commit.

That simple.

Use

<table style="table-layout:fixed;">

It will force table to set to 100% width.Then use this code

$('#dataTable').dataTable( {
        bAutoWidth: false, 
        aoColumns : [
          { sWidth: '45%' },
          { sWidth: '45%' },
          { sWidth: '10%' },
              ]
      });

(table id is dataTable and having 3 column) to specify length to each cell

Your error appears when you have modified a file and the branch that you are switching to has changes for this file too (from latest merge point).

Your options, as I see it, are - commit, and then amend this commit with extra changes (you can modify commits in git, as long as they're not pushed); or - use stash:

git stash save your-file-name
git checkout master
# do whatever you had to do with master
git checkout staging
git stash pop

git stash save will create stash that contains your changes, but it isn't associated with any commit or even branch. git stash pop will apply latest stash entry to your current branch, restoring saved changes and removing it from stash.

Another thing to check before you start playing with Xcode preferences is:

Select your target and go to Build Settings > Packaging > Wrapper Extension

The value there should be: app

If not double click it and type "app" without the qoutes.

Personally, I wouldn't use the LIKE string comparison on the ID field or any other numeric field. It doesn't make sense for a search for ID# "216" to return 16216, 21651, 3216087, 5321668..., and so on and so forth; likewise with salary.

Also, if you want to use prepared statements to prevent SQL injections, you would use a query string like:

SELECT * FROM job WHERE `position` LIKE CONCAT('%', ? ,'%') OR ...

If you have a very complex class with a lot of options of which only some combinations are valid, consider using a Builder. Works very well both codewise but also logically.

The Builder is a nested class with methods only designed to set fields, and then the ComplexClass constructor only takes such a Builder as an argument.

Edit: The ComplexClass constructor can ensure that the state in the Builder is valid. This is very hard to do if you just use setters on ComplexClass.

For those encountering this same error when connecting to a local site with a self-signed certificate, the following blog post helped me out.

http://brainof-dave.blogspot.com.au/2008/08/remote-certificate-is-invalid-according.html

public static double reverse(int num)

        counter++;
        num1 = num1/10;
    }
    while(counter >= 0)
    {
        int lastdigit = num%10;
        ret += Math.pow(10, counter-1) * lastdigit;
        num = num/10;
        counter--;  
    }
    return ret;
}

Yes, the performance difference is significant. See the KB article "How to improve string concatenation performance in Visual C#".

I have always tried to code for clarity first, and then optimize for performance later. That's much easier than doing it the other way around! However, having seen the enormous performance difference in my applications between the two, I now think about it a little more carefully.

Luckily, it's relatively straightforward to run performance analysis on your code to see where you're spending the time, and then to modify it to use StringBuilder where needed.

You can use http://pingdom.com/ to check your app; if done every minute or so, heroku won't idle your app and won't need to spin-up.

SELECT *
FROM A.tableA JOIN B.tableB 

or

SELECT *
  FROM A.tableA JOIN B.tableB
  ON A.tableA.id = B.tableB.a_id;

You can try out wsdl validator http://docs.wso2.org/wiki/display/ESB451/WSDL+Validator

Generally speaking, these days with any modern compiler worrying about inlining anything is pretty much a waste of time. The compiler should actually optimize all of these considerations for you through its own analysis of the code and your specification of the optimization flags passed to the compiler. If you care about speed, tell the compiler to optimize for speed. If you care about space, tell the compiler to optimize for space. As another answer alluded to, a decent compiler will even inline automatically if it really makes sense.

Also, as others have stated, using inline does not guarantee inline of anything. If you want to guarantee it, you will have to define a macro instead of an inline function to do it.

When to inline and/or define a macro to force inclusion? - Only when you have a demonstrated and necessary proven increase in speed for a critical section of code that is known to have an affect on the overall performance of the application.

Solution for WebKit browsers

From the MDN docs for the :-webkit-autofill CSS pseudo-class:

The :-webkit-autofill CSS pseudo-class matches when an element has its value autofilled by the browser

We can define a void transition css rule on the desired <input> element once it is :-webkit-autofilled. JS will then be able to hook onto the animationstart event.

Credits to the Klarna UI team. See their nice implementation here:

• CSS rules
• JS hook

Try this:

mail_accounts[0].encode("ascii")

You can also achieve this using a CSS Grids framework, such as YUI Grids or Blue Print CSS. They solve alot of the cross browser issues and make more sophisticated column layouts possible for use mere mortals.

str.split (" ") 
res27: Array[java.lang.String] = Array(a, +, b, -, c, *, d, /, e, <, f, >, g, >=, h, <=, i, ==, j)

To make sure that your font is cross-browser compatible, make sure that you use this syntax:

@font-face {
    font-family: 'Comfortaa Regular';
    src: url('Comfortaa.eot');
    src: local('Comfortaa Regular'), 
         local('Comfortaa'), 
         url('Comfortaa.ttf') format('truetype'),
         url('Comfortaa.svg#font') format('svg'); 
}

Taken from here.

let's do try and checkout For Swift 3...

UIView.transition(with: mysuperview, duration: 0.75, options:UIViewAnimationOptions.transitionFlipFromRight , animations: {
    myview.removeFromSuperview()
}, completion: nil)

You should define a key name while storing data to local storage which should be a string and value should be a string

 localStorage.setItem('dataSource', this.dataSource.length);

and to print, you should use getItem

console.log(localStorage.getItem('dataSource'));

setInterval(moveItem, 2000);

is the way to execute the function moveItem every 2 seconds. The main problem in your code is that you're calling setInterval inside of, rather than outside of, the callback. If I understand what you're trying to do, you can use this:

function moveItem() {
    jQuery('.stripTransmitter ul li a').trigger('click');
}

setInterval(moveItem, 2000);

N.B.:Don't pass strings to setTimeout or setInterval - best practice is to pass an anonymous function or a function identifier (as I did above). Also, be careful to not mix single and double quotes. Pick one and stick with it.

The simple example presented on Wikipedia worked for me. (you can read the complete description at http://en.wikipedia.org/wiki/Circular_dependency#Example_of_circular_dependencies_in_C.2B.2B )

File '''a.h''':

#ifndef A_H
#define A_H

File '''b.h''':

#ifndef B_H
#define B_H

class A;    //forward declaration

class B {
public:
    A* a;
};
#endif //B_H

File '''main.cpp''':

#include "a.h"
#include "b.h"

int main() {
    A a;
    B b;
    a.b = &b;
    b.a = &a;
}

You can get it like this also.

filepath = os.path.abspath(f.name)

use "\p{Pd}" without quotes to match any type of hyphen. The '-' character is just one type of hyphen which also happens to be a special character in Regex.

I wrote a module win-node-env with which you can run your command just like you would in *nix.

NODE_ENV=production node myapp/app.js

It works by creating a NODE_ENV.cmd that sets the NODE_ENV environment variable and spawns a child process with the rest of the command and its args.

Just install it (globally), and run your npm script commands, it should automatically make them work.

npm install -g win-node-env

Yes this is possible Since the question is update, this solution can only gives you the embed url not the HLS url, check @JAL answer. with the ressource search.list and the parameters:

* part: id
* channelId: UCURGpU4lj3dat246rysrWsw
* eventType: live
* type: video

Request :

GET https://www.googleapis.com/youtube/v3/search?part=snippet&channelId=UCURGpU4lj3dat246rysrWsw&eventType=live&type=video&key={YOUR_API_KEY}

Result:

 "items": [
  {
   "kind": "youtube#searchResult",
   "etag": "\"DsOZ7qVJA4mxdTxZeNzis6uE6ck/enc3-yCp8APGcoiU_KH-mSKr4Yo\"",
   "id": {
    "kind": "youtube#video",
    "videoId": "WVZpCdHq3Qg"
   }
  },

Then get the videoID value WVZpCdHq3Qg for example and add the value to this url:

https://www.youtube.com/embed/ + videoID
https://www.youtube.com/watch?v= + videoID

I had same problem to find a way to check whether ASP.NET 4.5 is on the Server. Because v4.5 is in place replace to v4.0, if you look at c:\windows\Microsoft.NET\Framework, you will not see v4.5 folder. Actually there is a simple way to see the version installed in the machine. Under Windows Server 2008 or Windows 7, just go to control panel -> Programs and Features, you will find "Microsoft .NET Framework 4.5" if it is installed.

System images are pre-installed Android operating systems, and are only used by emulators. If you use your real Android device for debugging, you no longer need them, so you can remove them all.

The cleanest way to remove them is using SDK Manager. Open up SDK Manager and uncheck those system images and then apply.

Also feel free to remove other components (e.g. old SDK levels) that are of no use.

In the first case you are creating the object on the heap using new. In the second case you are creating the object on the stack, so it will be disposed of when going out of scope. In C++ you'll need to delete objects on the heapexplicitly using delete when you don't Need them anymore.

To call a static method from a class, do

Singleton* singleton = Singleton::get_sample();

in your main-function or wherever.

For the extension method fans:

public static bool RegexStartsWith(this string str, params string[] patterns)
{
    return patterns.Any(pattern => 
       Regex.Match(str, "^("+pattern+")").Success);
}

Usage

var answer = str.RegexStartsWith("mailto","ftp","joe");
//or
var answer2 = str.RegexStartsWith("mailto|ftp|joe");
//or
bool startsWithWhiteSpace = "  does this start with space or tab?".RegexStartsWith(@"\s");

Use the method .rdd like this:

rdd = df.rdd

As others stated, it's likely failing because the requested key doesn't exist in the array. I have a helper function here that takes the array, the suspected key, as well as a default return in the event the key does not exist.

    protected function _getArrayValue($array, $key, $default = null)
    {
        if (isset($array[$key])) return $array[$key];
        return $default;
    }

hope it helps.

This issue appears when you have a running console at the time you try to run other (or the same) program.

I had this problem during executing a program on Sublime Text while I had another one running on DevC++ already.

Yes it's possible, just add inline styles for the element which you adding after or before, Example

 <style>
     .horizontalProgress:after { width: 45%; }
 </style><!-- Change Value from Here -->

 <div class="horizontalProgress"></div>

If I remember correctly, you'll need to set the netbeans_jdkhome property in your netbeans config file. Should be in your etc/netbeans.conf file.

My answer is basically the same as the others but I think there are two other important things to do:

1. Declare a virtual destructor in your interface or make a protected non-virtual one to avoid undefined behaviours if someone tries to delete an object of type IDemo.

2. Use virtual inheritance to avoid problems whith multiple inheritance. (There is more often multiple inheritance when we use interfaces.)

And like other answers:

• Make a class with pure virtual methods.

• Use the interface by creating another class that overrides those virtual methods.

  class IDemo
  {
      public:
          virtual void OverrideMe() = 0;
          virtual ~IDemo() {}
  }
  

  Or

  class IDemo
  {
      public:
          virtual void OverrideMe() = 0;
      protected:
          ~IDemo() {}
  }
  

  And

  class Child : virtual public IDemo
  {
      public:
          virtual void OverrideMe()
          {
              //do stuff
          }
  }
  

You can perform different approaches to work around this. The best approach is, if your both buttons are suppose to do the same job, you can define a third function to do the job. for example :

private void SubGraphButton_Click(object sender, RoutedEventArgs args)
{
    myJob()  
}

private void ChildNode_Click(object sender, RoutedEventArgs args)
{
    myJob()
}

private void myJob()
{
    // Your code here
}

but if you are still persisting on doing it in your way, the best action is :

private void SubGraphButton_Click(object sender, RoutedEventArgs args)
{
}

private void ChildNode_Click(object sender, RoutedEventArgs args)
{
   SubGraphButton_Click.PerformClick();
}

Thanks for the help. I've managed to get it working now so thought I would post so that the others can use to help them.

Server:

public class Server {
    public static void main(String[] args) throws IOException {
        ServerSocket serverSocket = null;

        try {
            serverSocket = new ServerSocket(4444);
        } catch (IOException ex) {
            System.out.println("Can't setup server on this port number. ");
        }

        Socket socket = null;
        InputStream in = null;
        OutputStream out = null;
        
        try {
            socket = serverSocket.accept();
        } catch (IOException ex) {
            System.out.println("Can't accept client connection. ");
        }
        
        try {
            in = socket.getInputStream();
        } catch (IOException ex) {
            System.out.println("Can't get socket input stream. ");
        }

        try {
            out = new FileOutputStream("M:\\test2.xml");
        } catch (FileNotFoundException ex) {
            System.out.println("File not found. ");
        }

        byte[] bytes = new byte[16*1024];

        int count;
        while ((count = in.read(bytes)) > 0) {
            out.write(bytes, 0, count);
        }

        out.close();
        in.close();
        socket.close();
        serverSocket.close();
    }
}

and the Client:

public class Client {
    public static void main(String[] args) throws IOException {
        Socket socket = null;
        String host = "127.0.0.1";

        socket = new Socket(host, 4444);
        
        File file = new File("M:\\test.xml");
        // Get the size of the file
        long length = file.length();
        byte[] bytes = new byte[16 * 1024];
        InputStream in = new FileInputStream(file);
        OutputStream out = socket.getOutputStream();
        
        int count;
        while ((count = in.read(bytes)) > 0) {
            out.write(bytes, 0, count);
        }

        out.close();
        in.close();
        socket.close();
    }
}

You can do direct SQL to have a single query for both tables. I'll provide a sanitized query example to hopefully keep people from putting variables directly into the string itself (SQL injection danger), even though this example didn't specify the need for it:

@results = []
ActiveRecord::Base.connection.select_all(
  ActiveRecord::Base.send(:sanitize_sql_array, 
   ["... your SQL query goes here and ?, ?, ? are replaced...;", a, b, c])
).each do |record|
  # instead of an array of hashes, you could put in a custom object with attributes
  @results << {col_a_name: record["col_a_name"], col_b_name: record["col_b_name"], ...}
end

Edit: as Huy said, a simple way is ActiveRecord::Base.connection.execute("..."). Another way is ActiveRecord::Base.connection.exec_query('...').rows. And you can use native prepared statements, e.g. if using postgres, prepared statement can be done with raw_connection, prepare, and exec_prepared as described in https://stackoverflow.com/a/13806512/178651

You can also put raw SQL fragments into ActiveRecord relational queries: http://guides.rubyonrails.org/active_record_querying.html and in associations, scopes, etc. You could probably construct the same SQL with ActiveRecord relational queries and can do cool things with ARel as Ernie mentions in http://erniemiller.org/2010/03/28/advanced-activerecord-3-queries-with-arel/. And, of course there are other ORMs, gems, etc.

If this is going to be used a lot and adding indices won't cause other performance/resource issues, consider adding an index in the DB for payment_details.created_at and for payment_errors.created_at.

If lots of records and not all records need to show up at once, consider using pagination:

• https://www.ruby-toolbox.com/categories/pagination
• https://github.com/mislav/will_paginate

If you need to paginate, consider creating a view in the DB first called payment_records which combines the payment_details and payment_errors tables, then have a model for the view (which will be read-only). Some DBs support materialized views, which might be a good idea for performance.

Also consider hardware or VM specs on Rails server and DB server, config, disk space, network speed/latency/etc., proximity, etc. And consider putting DB on different server/VM than the Rails app if you haven't, etc.

newVariable = originalVariable.valueOf();

for objects you can use, b = Object.assign({},a);

An alternative would be add the public half of the user's key to the authorized-keys file on the target system. On the system you are initiating the transfer from, you can run an ssh-agent daemon and add the private half of the key to the agent. The batch job can then be configured to use the agent to get the private key, rather than prompting for the key's password.

This should be do-able on either a UNIX/Linux system or on Windows platform using pageant and pscp.

In my case I used below configuration at VM options in IntelliJ , it was not picking the local configurations but after a restart of IntelliJ it picked configuration details from IntelliJ and service started running.

Update using the wonderful requests library. Note we are using the HEAD request, which should happen more quickly then a full GET or POST request.

import requests
try:
    r = requests.head("https://stackoverflow.com")
    print(r.status_code)
    # prints the int of the status code. Find more at httpstatusrappers.com :)
except requests.ConnectionError:
    print("failed to connect")

You are using a forward declaration for the type MainWindowClass. That's fine, but it also means that you can only declare a pointer or reference to that type. Otherwise the compiler has no idea how to allocate the parent object as it doesn't know the size of the forward declared type (or if it actually has a parameterless constructor, etc.)

So, you either want:

// forward declaration, details unknown
class A;

class B {
  A *a;  // pointer to A, ok
};

Or, if you can't use a pointer or reference....

// declaration of A
#include "A.h"

class B {
  A a;  // ok, declaration of A is known
};

At some point, the compiler needs to know the details of A.

If you are only storing a pointer to A then it doesn't need those details when you declare B. It needs them at some point (whenever you actually dereference the pointer to A), which will likely be in the implementation file, where you will need to include the header which contains the declaration of the class A.

// B.h
// header file

// forward declaration, details unknown
class A;

class B {
public: 
    void foo();
private:
  A *a;  // pointer to A, ok
};

// B.cpp
// implementation file

#include "B.h"
#include "A.h"  // declaration of A

B::foo() {
    // here we need to know the declaration of A
    a->whatever();
}

Is your website also on the oxfordlearnersdictionaries.com domain? or your trying to make a call to a domain and the same origin policy is blocking you?

Unless you have permission to set header via CORS on the oxfordlearnersdictionaries.com domain you may want to look for another approach.

My OS architecture is 64-bit so downloaded Eclipse Oxygen 64-bit version and got this error. Tried various solutions posted here but didn't help. Then downloaded Eclipse Oxygen 32-bit version and it works well.

C is the bare-bones, simple, clean language that makes you do everything yourself. It doesn't hold your hand, it doesn't stop you from shooting yourself in the foot. But it has everything you need to do what you want.

C++ is C with classes added, and then a whole bunch of other things, and then some more stuff. It doesn't hold your hand, but it'll let you hold your own hand, with add-on GC, or RAII and smart-pointers. If there's something you want to accomplish, chances are there's a way to abuse the template system to give you a relatively easy syntax for it. (moreso with C++0x). This complexity also gives you the power to accidentally create a dozen instances of yourself and shoot them all in the foot.

C# is Microsoft's stab at improving on C++ and Java. Tons of syntactical features, but no where near the complexity of C++. It runs in a full managed environment, so memory management is done for you. It does let you "get dirty" and use unsafe code if you need to, but it's not the default, and you have to do some work to shoot yourself.

addEventListener is the proper DOM method to use for attaching event handlers.

Internet Explorer (up to version 8) used an alternate attachEvent method.

Internet Explorer 9 supports the proper addEventListener method.

The following should be an attempt to write a cross-browser addEvent function.

function addEvent(evnt, elem, func) {
   if (elem.addEventListener)  // W3C DOM
      elem.addEventListener(evnt,func,false);
   else if (elem.attachEvent) { // IE DOM
      elem.attachEvent("on"+evnt, func);
   }
   else { // No much to do
      elem["on"+evnt] = func;
   }
}

var str = "123, 124, 234,252";
var arr = str.split(",");
for(var i=0;i<arr.length;i++) {
    arr[i] = ++arr[i];
}

The error occurs when the DNS resolution fails. Check if you can wget (or curl) the api url from the command line. Changing the DNS server and testing it might help.

I've used PDFBox with good success. Here's a sample of what the code looks like (back from version 0.7.2), that likely came from one of the provided examples:

// load the document
System.out.println("Reading document: " + filename);
PDDocument doc = null;                                                                                                                                                                                                          
doc = PDDocument.load(filename);

// look at all the document information
PDDocumentInformation info = doc.getDocumentInformation();
COSDictionary dict = info.getDictionary();
List l = dict.keyList();
for (Object o : l) {
    //System.out.println(o.toString() + " " + dict.getString(o));
    System.out.println(o.toString());
}

// look at the document catalog
PDDocumentCatalog cat = doc.getDocumentCatalog();
System.out.println("Catalog:" + cat);

List<PDPage> lp = cat.getAllPages();
System.out.println("# Pages: " + lp.size());
PDPage page = lp.get(4);
System.out.println("Page: " + page);
System.out.println("\tCropBox: " + page.getCropBox());
System.out.println("\tMediaBox: " + page.getMediaBox());
System.out.println("\tResources: " + page.getResources());

no control over the dialog box, if you had control over the dialog box you could write obtrusive javascript code. (Its is not a good idea to use alert for anything except debugging)

$('#dropdownid').empty();

That will remove all <option> elements underneath the dropdown element.

If you want to unselect selected items, go with the code from Russ.

To make a text default in a select box use the $form->select() method. Here is how you do it.

$options = array('m'=>'Male','f'=>'Female','n'=>'neutral');

$form->select('Model.name',$options,'f');

The above code will select Female in the list box by default.

Use XmlDocument.Load() method to load XML from your file. Then use XmlDocument.InnerXml property to get XML string.

XmlDocument doc = new XmlDocument();
doc.Load("path to your file");
string xmlcontents = doc.InnerXml;

@tux answer is great, just wanted to add that you can use go get to update a specific package:

go get -u full_package_name

Delegates Overview

Delegates have the following properties:

• Delegates are similar to C++ function pointers, but are type safe.
• Delegates allow methods to be passed as parameters.
• Delegates can be used to define callback methods.
• Delegates can be chained together; for example, multiple methods can be called on a single event.
• Methods don't need to match the delegate signature exactly. For more information, see Covariance and Contra variance.
• C# version 2.0 introduces the concept of Anonymous Methods, which permit code blocks to be passed as parameters in place of a separately defined method.

If you use this:

body {
    overflow: overlay;
}

The scrollbar will then also take transparent backgrounds across the page. This will also put the scrollbar inside the page instead of removing some of the width to put in the scrollbar.

Here is a demo code. I wasn't able to put it inside any of the codepen or jsfiddle, apperantly it took me a while until I figured out, but they don't show the transparency, and I don't know why.

But putting this in a HTML file should go fine.

Was able to put it on fiddle: https://jsfiddle.net/3awLgj5v/

_x000D_
</body>_x000D_
</html>

Best way to test it is to create a local html file, I guess.

You can also apply that on other elements, such as any scrolling box. While using inspector mode, it could be that you have to put the overflow to hidden and then back to anything else. It probably needed to refresh. After that it should be possible working on scrollbar without having to refresh it again. Just note that was for the inspector mode.

string[] lines = input.Split(new[] { '\r', '\n' }, StringSplitOptions.RemoveEmptyEntries);

As has been said, using unset is different with arrays as well

$ foo=(4 5 6)

$ foo[2]=

$ echo ${#foo[*]}
3

$ unset foo[2]

$ echo ${#foo[*]}
2

You can also use @Captor annotated ArgumentCaptor. For example:

@Mock
List<String> mockedList;

@Captor
ArgumentCaptor<String> argCaptor;

@BeforeTest
public void init() {
    //Initialize objects annotated with @Mock, @Captor and @Spy.
    MockitoAnnotations.initMocks(this);
}

@Test
public void shouldCallAddMethodTwice() {
    mockedList.add("one");
    mockedList.add("two");
    Mockito.verify(mockedList, times(2)).add(argCaptor.capture());

    assertEquals("one", argCaptor.getAllValues().get(0));
    assertEquals("two", argCaptor.getAllValues().get(1));
}

We can generate tuples from a list comprehension. The following one adds two numbers sequentially into a tuple and gives a list from numbers 0-9.

>>> print k
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99]
>>> r= [tuple(k[i:i+2]) for i in xrange(10) if not i%2]
>>> print r
[(0, 1), (2, 3), (4, 5), (6, 7), (8, 9)]

If you have a newer distro with a newer systemd (systemd version 236 or newer), you can set the values of StandardOutput or StandardError to file:YOUR_ABSPATH_FILENAME.

Long story:

In newer versions of systemd there is a relatively new option (the github request is from 2016 ish and the enhancement is merged/closed 2017 ish) where you can set the values of StandardOutput or StandardError to file:YOUR_ABSPATH_FILENAME. The file:path option is documented in the most recent systemd.exec man page.

This new feature is relatively new and so is not available for older distros like centos-7 (or any centos before that).

A solution is to use the include statement with remote_user var (describe there : http://docs.ansible.com/playbooks_roles.html) but it has to be done at playbook instead of task level.

CREATE FUNCTION FN_RemoveNonNumeric (@Input NVARCHAR(512))
RETURNS NVARCHAR(512)
AS
BEGIN
DECLARE @Trimmed NVARCHAR(512)

SELECT @Trimmed = @Input

WHILE PATINDEX('%[^0-9]%', @Trimmed) > 0
    SELECT @Trimmed = REPLACE(@Trimmed, SUBSTRING(@Trimmed, PATINDEX('%[^0-9]%', @Trimmed), 1), '')

RETURN @Trimmed
END

GO

SELECT dbo.FN_RemoveNonNumeric('ABCDE# 123')

I like @WilliamLeung's pure JavaScript solution, but sometimes you need to make changes in existing array to keep a reference to object.

function listToTree(data, options) {
  options = options || {};
  var ID_KEY = options.idKey || 'id';
  var PARENT_KEY = options.parentKey || 'parent';
  var CHILDREN_KEY = options.childrenKey || 'children';

  var item, id, parentId;
  var map = {};
    for(var i = 0; i < data.length; i++ ) { // make cache
    if(data[i][ID_KEY]){
      map[data[i][ID_KEY]] = data[i];
      data[i][CHILDREN_KEY] = [];
    }
  }
  for (var i = 0; i < data.length; i++) {
    if(data[i][PARENT_KEY]) { // is a child
      if(map[data[i][PARENT_KEY]]) // for dirty data
      {
        map[data[i][PARENT_KEY]][CHILDREN_KEY].push(data[i]); // add child to parent
        data.splice( i, 1 ); // remove from root
        i--; // iterator correction
      } else {
        data[i][PARENT_KEY] = 0; // clean dirty data
      }
    }
  };
  return data;
}

Exapmle: https://jsfiddle.net/kqw1qsf0/17/

How about this?

# Removes all objects except the specified & the function itself.

rme <- function(except=NULL){
  except = ifelse(is.character(except), except, deparse(substitute(except)))
  rm(list=setdiff(ls(envir=.GlobalEnv), c(except,"rme")), envir=.GlobalEnv)
}

Unless you have GNU awk 4.1.0 or later...

You won't have such an option as sed's -i option so instead do:

$ awk '{print $0}' file > tmp && mv tmp file

Note: the -i is not magic, it is also creating a temporary file sed just handles it for you.

As of GNU awk 4.1.0...

GNU awk added this functionality in version 4.1.0 (released 10/05/2013). It is not as straight forwards as just giving the -i option as described in the released notes:

The new -i option (from xgawk) is used for loading awk library files. This differs from -f in that the first non-option argument is treated as a script.

You need to use the bundled inplace.awk include file to invoke the extension properly like so:

$ cat file
123 abc
456 def
789 hij

$ gawk -i inplace '{print $1}' file

$ cat file
123
456
789

The variable INPLACE_SUFFIX can be used to specify the extension for a backup file:

$ gawk -i inplace -v INPLACE_SUFFIX=.bak '{print $1}' file

$ cat file
123
456
789

$ cat file.bak
123 abc
456 def
789 hij

I am happy this feature has been added but to me, the implementation isn't very awkish as the power comes from the conciseness of the language and -i inplace is 8 characters too long i.m.o.

Here is a link to the manual for the official word.

setBackground() is the right method to use. Did you repaint after you changed it? If you change it before you make the panel (or its containing frame) visible it should work

I have created a working CodePen example to demonstrate how you might accomplish your goals.

I added ng-click to the <form> and removed the logic from your button:

<form name="addRelation" data-ng-click="save(model)">
...
<input class="btn" type="submit" value="SAVE" />

Here's the updated template:

<section ng-app="app" ng-controller="MainCtrl">
  <form class="well" name="addRelation" data-ng-click="save(model)">
    <label>First Name</label>
    <input type="text" placeholder="First Name" data-ng-model="model.firstName" id="FirstName" name="FirstName" required/><br/>
    <span class="text-error" data-ng-show="addRelation.submitted && addRelation.FirstName.$invalid">First Name is required</span><br/>
    <label>Last Name</label>
    <input type="text" placeholder="Last Name" data-ng-model="model.lastName" id="LastName" name="LastName" required/><br/>
    <span class="text-error" data-ng-show="addRelation.submitted && addRelation.LastName.$invalid">Last Name is required</span><br/>
    <label>Email</label>
    <input type="email" placeholder="Email" data-ng-model="model.email" id="Email" name="Email" required/><br/>
    <span class="text-error" data-ng-show="addRelation.submitted && addRelation.Email.$error.required">Email address is required</span>
    <span class="text-error" data-ng-show="addRelation.submitted && addRelation.Email.$error.email">Email address is not valid</span><br/>
    <input class="btn" type="submit" value="SAVE" />  
  </form>
</section>

and controller code:

app.controller('MainCtrl', function($scope) {  
  $scope.save = function(model) {
    $scope.addRelation.submitted = true;

    if($scope.addRelation.$valid) {
      // submit to db
      console.log(model); 
    } else {
      console.log('Errors in form data');
    }
  };
});

I hope this helps.

In case you have a .properties file or a .ini file

Actually in case if you have any file that has key value pairs like this:

someKey=someValue
someOtherKey=someOtherValue

You can import that into webpack by a npm module called properties-reader

I found this really helpful since I'm integrating react with Java Spring framework where there is already an application.properties file. This helps me to keep all config together in one place.

1. Import that from dependencies section in package.json

"properties-reader": "0.0.16"

2. Import this module into webpack.config.js on top

const PropertiesReader = require('properties-reader');

3. Read the properties file

const appProperties = PropertiesReader('Path/to/your/properties.file')._properties;

4. Import this constant as config

externals: { 'Config': JSON.stringify(appProperties) }

5. Use it as the same way as mentioned in the accepted answer

var Config = require('Config') fetchData(Config.serverUrl + '/Enterprises/...')

I had the same error here MacOSX 10.11 - it seems ruby checks to see if any directory (including the parents) in the path are world writable. In my case there wasn't a /usr/local/bin present as nothing had created it.

Run this command in your terminal.Try this sudo chmod 775 /usr/local After this if you have any password on your mac , then you have to enter the password . Now this issue will be fix.

An answer that is not limited to the OP's case

The title of the question leads people here, so I decided to answer that question for everyone else since the OP's described case was so limited.

TL;DR

I finally settled on writing a function.

1. If you want 0 in case of non-int:

int(){ printf '%d' ${1:-} 2>/dev/null || :; }

2. If you want [empty_string] in case of non-int:

int(){ expr 0 + ${1:-} 2>/dev/null||:; }

3. If you want find the first int or [empty_string]:

int(){ expr ${1:-} : '[^0-9]*\([0-9]*\)' 2>/dev/null||:; }

4. If you want find the first int or 0:

# This is a combination of numbers 1 and 2
int(){ expr ${1:-} : '[^0-9]*\([0-9]*\)' 2>/dev/null||:; }

If you want to get a non-zero status code on non-int, remove the ||: (aka or true) but leave the ;

Tests

# Wrapped in parens to call a subprocess and not `set` options in the main bash process
# In other words, you can literally copy-paste this code block into your shell to test
( set -eu;
    tests=( 4 "5" "6foo" "bar7" "foo8.9bar" "baz" " " "" )
    test(){ echo; type int; for test in "${tests[@]}"; do echo "got '$(int $test)' from '$test'"; done; echo "got '$(int)' with no argument"; }

    int(){ printf '%d' ${1:-} 2>/dev/null||:; };
    test

    int(){ expr 0 + ${1:-} 2>/dev/null||:; }
    test

    int(){ expr ${1:-} : '[^0-9]*\([0-9]*\)' 2>/dev/null||:; }
    test

    int(){ printf '%d' $(expr ${1:-} : '[^0-9]*\([0-9]*\)' 2>/dev/null)||:; }
    test

    # unexpected inconsistent results from `bc`
    int(){ bc<<<"${1:-}" 2>/dev/null||:; }
    test
)

Hope this will assist anyone having the same error while importing CSV data into related tables. In my case the parent table was OK, but I got the error while importing data to the child table containing the foreign key. After temporarily removing the foregn key constraint on the child table, I managed to import the data and was suprised to find some of the values in the FK column having values of 0 (obviously this had been causing the error since the parent table did not have such values in its PK column). The cause was that, the data in my CSV column preceeding the FK column contained commas (which I was using as a field delimeter). Changing the delimeter for my CSV file solved the problem.

Readonly will not "grayout" the textbox and will still submit the value on a postback.

You can use this command:

I ran into this issue today. Here is my hacky solution.

I needed a fixed position element to transition up by 100 pixels as it loaded.

var delay = (ms) => new Promise(res => setTimeout(res, ms));
async function animateView(startPosition,elm){
  for(var i=0; i<101; i++){
    elm.style.top = `${(startPosition-i)}px`;
    await delay(1);
  }
}

In Swift 4, add @objc:

In the viewDidLoad:

let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.dismissKeyboard))
view.addGestureRecognizer(tap)

Function:

@objc func dismissKeyboard() {
  view.endEditing(true)
}

I created it a long time ago, related question

String.Format = function (b) {
    var a = arguments;
    return b.replace(/(\{\{\d\}\}|\{\d\})/g, function (b) {
        if (b.substring(0, 2) == "{{") return b;
        var c = parseInt(b.match(/\d/)[0]);
        return a[c + 1]
    })
};

Before you proceed to conda update --all command, first update conda with conda update conda command if you haven't update it for a long time. It happent to me (Python 2.7.13 on Anaconda 64 bits).

It's the first result on Google: http://docs.python.org/library/stdtypes.html#string-formatting

See also the new format() function: http://docs.python.org/library/stdtypes.html#str.format

I haven't timed it but I bet h5 is faster than pickle; the filesize with compression is almost certainly smaller.

import deepdish as dd
dd.io.save(filename, {'dict1': dict1, 'dict2': dict2}, compression=('blosc', 9))

I found another, rather quick and dirty, solution. If you use the low level approach to implement the WebSocket and you Implement the onOpen method yourself you receive an object implementing the WebSocket.Connection interface. This object has a setMaxIdleTime method which you can adjust.

Press Ctrl+C

When you start the server it mentions this in the startup text.

For me it started working after selecting "Remove additional files at destination" in File publish options under settings on the publish dialog.

OIDs being phased out

The core team responsible for Postgres is gradually phasing out OIDs.

Postgres 12 removes special behavior of OID columns

The use of OID as an optional system column on your tables is now removed from Postgres 12. You can no longer use:

• CREATE TABLE … WITH OIDS command
• default_with_oids (boolean) compatibility setting

The data type OID remains in Postgres 12. You can explicitly create a column of the type OID.

After migrating to Postgres 12, any optionally-defined system column oid will no longer be invisible by default. Performing a SELECT * will now include this column. Note that this extra “surprise” column may break naïvely written SQL code.

short answer, specific to OAuth2,

• HS256 user client secret to generate the token signature and same secret is required to validate the token in back-end. So you should have a copy of that secret in your back-end server to verify the signature.
• RS256 use public key encryption to sign the token.Signature(hash) will create using private key and it can verify using public key. So, no need of private key or client secret to store in back-end server, but back-end server will fetch the public key from openid configuration url in your tenant (https://[tenant]/.well-known/openid-configuration) to verify the token. KID parameter inside the access_toekn will use to detect the correct key(public) from openid-configuration.

Pure Javascript, without regular expression:

var result = replaceSpacesText.split(" ").join("");

I ran into this problem today. After spending most of the day trying to fix it, the only thing that ended up working was to create a new workspace and import my project into it. I hope this helps someone avoid all the trouble that I went through.

You should use the ISO-8601 format for string representations of dates - anything else is dependent on the SQL Server language and dateformat settings.

The ISO-8601 format for a DATETIME when using only the date is: YYYYMMDD (no dashes or antyhing!)

For a DATETIME with the time portion, it's YYYY-MM-DDTHH:MM:SS (with dashes, and a T in the middle to separate date and time portions).

If you want to convert a string to a DATE for SQL Server 2008 or newer, you can use YYYY-MM-DD (with the dashes) to achieve the same result. And don't ask me why this is so inconsistent and confusing - it just is, and you'll have to work with that for now.

So in your case, you should try:

declare @a datetime
declare @b datetime 

set @a = '2012-04-06T12:23:45'   -- 6th of April, 2012
set @b = '2012-08-06T21:10:12'   -- 6th of August, 2012

exec LogProcedure 'AccountLog', N'test', @a, @b

Furthermore - your stored proc has problem, since you're concatenating together datetime and string into a string, but you're not converting the datetime to string first, and also, you're forgetting the close quotes in your statement after both dates.

So change this line here to this:

IF @DateFirst <> '' and @DateLast <> ''
   SET @FinalSQL  = @FinalSQL + '  OR CONVERT(Date, DateLog) >= ''' + 
                    CONVERT(VARCHAR(50), @DateFirst, 126) +   -- convert @DateFirst to string for concatenation!
                    ''' AND CONVERT(Date, DateLog) <=''' +  -- you need closing quotes after @DateFirst!
                    CONVERT(VARCHAR(50), @DateLast, 126) + ''''      -- convert @DateLast to string and also: closing tags after that missing!

With these settings, and once you've fixed your stored procedure which contains problems right now, it will work.

set global sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

try this:

return $this->db->query("
     SELECT * FROM myTable 
     WHERE trans_id IN ( SELECT trans_id FROM myTable WHERE code='B') 
     AND code!='B'
     ")->result_array();

Swift 5

@imanuo answers is already great, but if you are working with an application full of number, you can consider an extension like this:

extension String {

    init(withInt int: Int, leadingZeros: Int = 2) {
        self.init(format: "%0\(leadingZeros)d", int)
    }

    func leadingZeros(_ zeros: Int) -> String {
        if let int = Int(self) {
            return String(withInt: int, leadingZeros: zeros)
        }
        print("Warning: \(self) is not an Int")
        return ""
    }
    
}

In this way you can call wherever:

String(withInt: 3) 
// prints 03

String(withInt: 23, leadingZeros: 4) 
// prints 0023

"42".leadingZeros(2)
// prints 42

"54".leadingZeros(3)
// prints 054

If you want to compare to a string literal you need to put it in (single) quotes:

<xsl:if test="Count != 'N/A'">

There is no OOTB feature at this moment which allows this. One way to achieve that could be to write a custom InputFormat and/or SerDe that will do this for you. You might this JIRA useful : https://issues.apache.org/jira/browse/HIVE-3751. (not related directly to your problem though).

Here's a clear picture:

Assuming we have branch-A and branch-B

We want to merge branch-B into branch-A

on branch-B -> A: switch to branch-A

on branch-A: git merge branch-B

As @Quartz mentioned, you can do something like

stage('Tests') {
    parallel(
        'Unit Tests': {
            container('node') {
                sh("npm test --cat=unit")
            }
        },
        'API Tests': {
            container('node') {
                sh("npm test --cat=acceptance")
            }
        }
    )
}

Not only to close the JFrame but also to trigger WindowListener events, try this:

myFrame.dispatchEvent(new WindowEvent(myFrame, WindowEvent.WINDOW_CLOSING));

You can't pull in blocks from an included file into a child template to override the parent template's blocks. However, you can specify a parent in a variable and have the base template specified in the context.

From the documentation:

{% extends variable %} uses the value of variable. If the variable evaluates to a string, Django will use that string as the name of the parent template. If the variable evaluates to a Template object, Django will use that object as the parent template.

Instead of separate "page1.html" and "page2.html", put {% extends base_template %} at the top of "commondata.html". And then in your view, define base_template to be either "base1.html" or "base2.html".

I think you want to cast your dt to a date and fix the format of your date literal:

SELECT *
FROM table
WHERE dt::date = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

Or the standard version:

SELECT *
FROM table
WHERE CAST(dt AS DATE) = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

The extract function doesn't understand "date" and it returns a number.

Morgan :- Morgan is a middleware which will help us to identify the clients who are accessing our application. Basically a logger.

To Use Morgan, We need to follow below steps :-

1. Install the morgan using below command:

npm install --save morgan

This will add morgan to json.package file

2. Include the morgan in your project

var morgan = require('morgan');

3> // create a write stream (in append mode)

var accessLogStream = fs.createWriteStream(
      path.join(__dirname, 'access.log'), {flags: 'a'}
 );
// setup the logger 
app.use(morgan('combined', {stream: accessLogStream}));

Note: Make sure you do not plumb above blindly make sure you have every conditions where you need .

Above will automatically create a access.log file to your root once user will access your app.

The file needs to add Component from core hence add the following import to the top

import { Component } from '@angular/core';

Here is a simpler solution. Override the onTouch() for the ScrollView OnTouchListener and return false if you want to bypass the scroll by touch. The programmatic scrolling still works and no need to extend the ScrollView class.

mScroller.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
  return isScrollable;
}
});

pprint.pprint() is a good tool for this job:

>>> import pprint
>>> cars = {'A':{'speed':70,
...         'color':2},
...         'B':{'speed':60,
...         'color':3}}
>>> pprint.pprint(cars, width=1)
{'A': {'color': 2,
       'speed': 70},
 'B': {'color': 3,

I usually prefer to work with deltas in translate animation, since it avoids a lot of confusion.

Try this out, see if it works for you:

TranslateAnimation anim = new TranslateAnimation(0, amountToMoveRight, 0, amountToMoveDown);
anim.setDuration(1000);

anim.setAnimationListener(new TranslateAnimation.AnimationListener() {

    @Override
    public void onAnimationStart(Animation animation) { }

    @Override
    public void onAnimationRepeat(Animation animation) { }

    @Override
    public void onAnimationEnd(Animation animation) 
    {
        FrameLayout.LayoutParams params = (FrameLayout.LayoutParams)view.getLayoutParams();
        params.topMargin += amountToMoveDown;
        params.leftMargin += amountToMoveRight;
        view.setLayoutParams(params);
    }
});

view.startAnimation(anim);

Make sure to make amountToMoveRight / amountToMoveDown final

Hope this helps :)

The highest-ranked answer by Mudassar Bashir using the "title" attribute seems the easiest way to do this, but it gives you less control over how the comment/tooltip is displayed.

I found that The answer by Christophe for a custom tooltip class seems to give much more control over the behavior of the comment/tooltip. Since the provided demo does not include a table, as per the question, here is a demo that includes a table.

Note that the "position" style for the parent element of the span (a in this case), must be set to "relative" so that the comment does not push the table contents around when it is displayed. It took me a little while to figure that out.

I had the same issue - it sorted itself out in ~3 hours after I uploaded the app to the Play console. According to Google:

Warning: It may take up to 2-3 hours after uploading the APK for Google Play to recognize your updated APK version. If you try to test your application before your uploaded APK is recognized by Google Play, your application will receive a ‘purchase cancelled’ response with an error message “This version of the application is not enabled for In-app Billing.

While the message is not the same, I suspect the root cause to be the same.

Parent table data missing causes the problem. In your problem non availability of data in "dbo.Sup_Item_Cat" causes the problem

This is a generic, HTML source ordered solution where:

• The first column in source order is fluid
• The second column in source order is fixed
  • This column can be floated left or right using CSS

Alternate solution is to use display: table-cell; which results in equal height columns.

From MSDN

// Create a request using a URL that can receive a post. 
WebRequest request = WebRequest.Create ("http://contoso.com/PostAccepter.aspx ");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = "This is a test that posts this string to a Web server.";
byte[] byteArray = Encoding.UTF8.GetBytes (postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream ();
// Write the data to the request stream.
dataStream.Write (byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close ();
// Get the response.
WebResponse response = request.GetResponse ();
// Display the status.
Console.WriteLine (((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Clean up the streams.
reader.Close ();
dataStream.Close ();
response.Close ();

Take into account that the information must be sent in the format key1=value1&key2=value2

I had the same issue as above and I am using PostgreSQL 10.5. I tried everything as above but nothing seems to be working.

Then I closed the pgadmin and opened a session for the PSQL terminal. Logged into the PSQL and connected to the database and schema respectively :

\c <DATABASE_NAME>;
set search_path to <SCHEMA_NAME>;

Then, restarted the pgadmin console and then I was able to work without issue in the query-tool of the pagadmin.

use spawn

import os
os.spawnlp(os.P_WAIT, 'cp', 'cp', 'index.html', '/dev/null')

New CKeditor doesn't have file manager included (CKFinder is payable). You can integrate free filemanager that is good looking and easy to implement in CKeditor.

http://labs.corefive.com/2009/10/30/an-open-file-manager-for-ckeditor-3-0/

You dowload it, copy it to your project. All instructions are there but you basically just put path to added filemanager index.html page in your code.

CKEDITOR.replace( 'meeting_notes',
{
startupFocus : true,
toolbar :
[
['ajaxsave'],
['Bold', 'Italic', 'Underline', '-', 'NumberedList', 'BulletedList', '-', 'Link', 'Unlink' ],
['Cut','Copy','Paste','PasteText'],
['Undo','Redo','-','RemoveFormat'],
['TextColor','BGColor'],
['Maximize', 'Image']
],
filebrowserUploadUrl : '/filemanager/index.html' // you must write path to filemanager where you have copied it.
});    

Most languages are supported (php, asp, MVC && aspx - ashx,...)).

While I was able to solve this problem in one computer following the other users solutions, the command netsh didn't solve the issue in one of my machines and even though the current user had administrator rights I was still getting the "HTTP could not register URL.... Your process does not have access rights to this namespace". So I'm sharing my solution in case you still don't get it to work with the other solutions too.

After also trying to give write permissions to the user in the physical directory of my website and getting no success, I finally decided trying to change IIS settings.

As the images below show, I configured the Physical Path Credentials of my website to connect as an specifc user, which was an admin account with DOMAIN\username and password, and this was enough to make the error disapear.

GlobalStrings.AddRange(localStrings);

Note: You cannot declare the list object using the interface (IList).
Documentation: List<T>.AddRange(IEnumerable<T>).

just use mCheckedPosition save status

            holder.checkBox.setChecked(position == mCheckedPostion);
            holder.checkBox.setOnClickListener(v -> {
                if (position == mCheckedPostion) {
                    holder.checkBox.setChecked(false);
                    mCheckedPostion = -1;
                } else {
                    mCheckedPostion = position;
                    notifyDataSetChanged();
                }
            });
        }

This will solve your problem

In more complicated build scenarios, it is common to break compilation into stages, with compilation and assembly happening first (output to object files), and linking object files into a final executable or library afterward--this prevents having to recompile all object files when their source files haven't changed. That's why including the linking flag -lm isn't working when you put it in CFLAGS (CFLAGS is used in the compilation stage).

The convention for libraries to be linked is to place them in either LOADLIBES or LDLIBS (GNU make includes both, but your mileage may vary):

LDLIBS=-lm

This should allow you to continue using the built-in rules rather than having to write your own linking rule. For other makes, there should be a flag to output built-in rules (for GNU make, this is -p). If your version of make does not have a built-in rule for linking (or if it does not have a placeholder for -l directives), you'll need to write your own:

client.o: client.c
    $(CC) $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c -o $@ $<

client: client.o
    $(CC) $(LDFLAGS) $(TARGET_ARCH) $^ $(LOADLIBES) $(LDLIBS) -o $@

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

You can do this by checking if the area formed by connecting the desired point to the vertices of your polygon matches the area of the polygon itself.

Or you could check if the sum of the inner angles from your point to each pair of two consecutive polygon vertices to your check point sums to 360, but I have the feeling that the first option is quicker because it doesn't involve divisions nor calculations of inverse of trigonometric functions.

I don't know what happens if your polygon has a hole inside it but it seems to me that the main idea can be adapted to this situation

You can as well post the question in a math community. I bet they have one million ways of doing that

Float won't convert into NVARCHAR directly, first we need to convert float into money datatype and then convert into NVARCHAR, see the examples below.

Example1

SELECT CAST(CAST(1234567890.1234  AS FLOAT) AS NVARCHAR(100))

output

1.23457e+009

Example2

SELECT CAST(CAST(CAST(1234567890.1234  AS FLOAT) AS MONEY) AS NVARCHAR(100))

output

1234567890.12

In Example2 value is converted into float to NVARCHAR

   <p id="text" onclick="func()">
    Click on text to change
</p>
<script>
function func()
{
    document.getElementById("text").style.color="red";
    document.getElementById("text").style.font="calibri";
}
</script>

Please ensure that your mongo DB is set Automatic and running at Control Panel/Administrative Tools/Services like below. That way you wont have to start mongod.exe manually each time.

Try this: Open given fiddle in CHROME

function sum() {
      var txtFirstNumberValue = document.getElementById('txt1').value;
      var txtSecondNumberValue = document.getElementById('txt2').value;
      var result = parseInt(txtFirstNumberValue) + parseInt(txtSecondNumberValue);
      if (!isNaN(result)) {
         document.getElementById('txt3').value = result;
      }
}

HTML

<input type="text" id="txt1"  onkeyup="sum();" />
<input type="text" id="txt2"  onkeyup="sum();" />
<input type="text" id="txt3" />

As for me, this approach is prettier:

String.prototype.embraceWith = function(tag) {
    return "<" + tag + ">" + this + "</" + tag + ">";
};

var results = [
  {type:"Fiat", model:500, color:"white"}, 
  {type:"Mercedes", model: "Benz", color:"black"},
  {type:"BMV", model: "X6", color:"black"}
];

var tableHeader = ("Type".embraceWith("th") + "Model".embraceWith("th") + "Color".embraceWith("th")).embraceWith("tr");
var tableBody = results.map(function(item) {
    return (item.type.embraceWith("td") + item.model.toString().embraceWith("td") + item.color.embraceWith("td")).embraceWith("tr")
}).join("");

var table = (tableHeader + tableBody).embraceWith("table");

$("#result-holder").append(table);

You might want to try the full login command:

mysql -h host -u root -p 

where host would be 127.0.0.1.

Do this just to make sure cooperation exists.

Using mysql -u root -p allows me to do a a lot of database searching, but refuses any database creation due to a path setting.

To alter the password expiry policy for a certain user profile in Oracle first check which profile the user is using:

select profile from DBA_USERS where username = '<username>';

Then you can change the limit to never expire using:

alter profile <profile_name> limit password_life_time UNLIMITED;

If you want to previously check the limit you may use:

select resource_name,limit from dba_profiles where profile='<profile_name>';

You can use this, but it only supports Firefox and Chrome.

$(element).bind('DOMSubtreeModified', function () {_x000D_
  var $this = this;_x000D_
  var updateHeight = function () {_x000D_
    var Height = $($this).height();_x000D_
    console.log(Height);_x000D_
  };_x000D_
  setTimeout(updateHeight, 2000);_x000D_
});

Stole a lot of this from other answers, but this is working in FF3 for me. It has upper-roman, uniform indenting, a close bracket.

@Martijn your order of function calls is slightly off. Try this instead:

x=-3:0.1:3;
y = x.^3;
plot(x,y), hold on
plot([-3 3], [0 0], 'k:')
hold off

To configure your project go through this video: https://www.youtube.com/watch?v=Zm2pKTW5z98 (Send Email from MySQL on Linux) It will work for any mysql version (5.5, 5.6, 5.7)

I will resolve if any error appear in above code, Just Inform in comment

The above answers are good and you can do it in a simple way also.

You can use the recursive method calls.

func vibrateTheDeviceContinuously() throws {
        
        // Added concurrent queue for next & Vibrate device
        DispatchQueue.global(qos: .utility).async {
            
            //Vibrate the device
            AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)

            self.incrementalCount += 1
            usleep(800000) // if you don't want, remove this line.

            do {
                if let isKeepBuzzing = self.iShouldKeepBuzzing , isKeepBuzzing == true {
                    try self.vibrateTheDeviceContinuously()
                }
                 else {
                    return 
                 }
                
            } catch  {
                //Exception handle
               print("exception")
            }
            
        }
    }

To stop the device vibration use the following line.

self.iShouldKeepBuzzing = false

I had the same issue. The target frameworks were fine for me. Still it was not working. I installed VS2010 sp1, and did a "Rebuild" on the PrjTest. Then it started working for me.

Just for the quirks of it, you can convert your string via babel-standalone

var str = "{ hello: 'world', places: ['Africa', 'America', 'Asia', 'Australia'] }";_x000D_
_x000D_
function toJSON() {_x000D_
  return {_x000D_
    visitor: {_x000D_
      Identifier(path) {_x000D_
        path.node.name = '"' + path.node.name + '"'_x000D_
      },_x000D_
      StringLiteral(path) {_x000D_
        delete path.node.extra_x000D_
      }_x000D_
    }_x000D_
  }_x000D_
}_x000D_
Babel.registerPlugin('toJSON', toJSON);_x000D_
var parsed = Babel.transform('(' + str + ')', {_x000D_
  plugins: ['toJSON']_x000D_
});_x000D_
var json = parsed.code.slice(1, -2)_x000D_
console.log(JSON.parse(json))

<script src="https://unpkg.com/@babel/standalone/babel.min.js"></script>

As it has been explained here, beside of multiple extensions that perform ad or script blocking you may aware that this may happen by file names as below:

Particularly in the AdBlock Plus the character string "-300x600" is causing the Failed to Load Resource ERR_BLOCKED_BY_CLIENT problem.

As shown in the picture, some of the images were blocked because of the '-300x600' pattern in their name, that particular text pattern matches an expression list pattern in the AdBlock Plus.

It's not a direct answer to the question, however I would suggest in most cases to simply set multiple classes to each element:

<div class="myclass one"></div>
<div class="myclass two></div>
<div class="myclass three"></div>

In this way you can set rules for all myclass elements and then more specific rules for one, two and three.

.myclass { color: #f00; }

.two { font-weight: bold; }

etc.

I recently came across Python 3 interpreter at CompileOnline.

Upload buttons are a pain to style because it styles the input and not the button.

but you can use this trick:

http://www.quirksmode.org/dom/inputfile.html

Summary:

1. Take a normal <input type="file"> and put it in an element with position: relative.

2. To this same parent element, add a normal <input> and an image, which have the correct styles. Position these elements absolutely, so that they occupy the same place as the <input type="file">.

3. Set the z-index of the <input type="file"> to 2 so that it lies on top of the styled input/image.

4. Finally, set the opacity of the <input type="file"> to 0. The <input type="file"> now becomes effectively invisible, and the styles input/image shines through, but you can still click on the "Browse" button. If the button is positioned on top of the image, the user appears to click on the image and gets the normal file selection window. (Note that you can't use visibility: hidden, because a truly invisible element is unclickable, too, and we need the to remain clickable)

Try this instead:

$journalName = str_replace(' ', '_', $journalName);

to remove white space

My problem was I had czech characters (c,ú,u,á,ó) in the project folder path.

Try this. It will work for sure.

var userInput = $('#txt_name').attr('value')

You should check out the moment.js api, it is very easy to use and has lots of built in features.

I think for your problem, you could use something like this:

var unixTimestamp = moment('2012.08.10', 'YYYY.MM.DD').unix();

Well if you want fully transparent than you can use

border: 5px solid transparent;

If you mean opaque/transparent, than you can use

border: 5px solid rgba(255, 255, 255, .5);

Here, a means alpha, which you can scale, 0-1.

Also some might suggest you to use opacity which does the same job as well, the only difference is it will result in child elements getting opaque too, yes, there are some work arounds but rgba seems better than using opacity.

For older browsers, always declare the background color using #(hex) just as a fall back, so that if old browsers doesn't recognize the rgba, they will apply the hex color to your element.

Demo

Demo 2 (With a background image for nested div)

Demo 3 (With an img tag instead of a background-image)

body {
    background: url(http://www.desktopas.com/files/2013/06/Images-1920x1200.jpg);   
}

div.wrap {
    border: 5px solid #fff; /* Fall back, not used in fiddle */
    border: 5px solid rgba(255, 255, 255, .5);
    height: 400px;
    width: 400px;
    margin: 50px;
    border-radius: 50%;
}

div.inner {
    background: #fff; /* Fall back, not used in fiddle */
    background: rgba(255, 255, 255, .5);
    height: 380px;
    width: 380px;
    border-radius: 50%; 
    margin: auto; /* Horizontal Center */
    margin-top: 10px; /* Vertical Center ... Yea I know, that's 
                         manually calculated*/
}

Note (For Demo 3): Image will be scaled according to the height and width provided so make sure it doesn't break the scaling ratio.

In views with {{}} and/or ng-model, Angular is setting up $watch()es for you behind the scenes.

By default $watch compares by reference. If you set the third parameter to $watch to true, Angular will instead "shallow" watch the object for changes. For arrays this means comparing the array items, for object maps this means watching the properties. So this should do what you want:

$scope.$watch('myModel', function() { ... }, true);

Update: Angular v1.2 added a new method for this, `$watchCollection():

$scope.$watchCollection('myModel', function() { ... });

Note that the word "shallow" is used to describe the comparison rather than "deep" because references are not followed -- e.g., if the watched object contains a property value that is a reference to another object, that reference is not followed to compare the other object.

This should suffice your purpose. It compares two collections and checks if one collection has the values matching those in the other collection

fea_Features.Where(s => selectedFeatures.Contains(s.feaId))

Use inspect.cleandoc like so:

def method():
    string = inspect.cleandoc("""
        line one
        line two
        line three""")

Relative indentation will be maintained as expected. As commented below, if you want to keep preceding empty lines, use textwrap.dedent. However that also keeps the first line break.

Note: It's good practice to indent logical blocks of code under its related context to clarify the structure. E.g. the multi-line string belonging to the variable string.

You need to call repaint() and revalidate(). The former tells Swing that an area of the window is dirty (which is necessary to erase the image of the old children removed by removeAll()); the latter tells the layout manager to recalculate the layout (which is necessary when adding components). This should cause children of the panel to repaint, but may not cause the panel itself to do so (see this for the list of repaint triggers).

On a more general note: rather than reusing the original panel, I'd recommend building a new panel and swapping them at the parent.

Android now supports adding a Space view between views. It's available from 4.0 ICS onwards.

The toggle tells Bootstrap what to do and the target tells Bootstrap which element is going to open. So whenever a link like that is clicked, a modal with an id of “basicModal” will appear.

The report might want to access a DataSource or DataView where the AD user (or AD group) has insuficcient access rights.

Make sure you check out the following URLs:

• http://REPORTSERVERNAME/Reports/Pages/Folder.aspx?ItemPath=%2fDataSources
• http://REPORTSERVERNAME/Reports/Pages/Folder.aspx?ItemPath=%2fDataSets

Then choose Folder Settings

(or the appropriate individual DataSource or DataSet) and select Security. The user group needs to have the Browser permission.

r is a numpy (rec)array. So r["dt"] >= startdate is also a (boolean) array. For numpy arrays the & operation returns the elementwise-and of the two boolean arrays.

The NumPy developers felt there was no one commonly understood way to evaluate an array in boolean context: it could mean True if any element is True, or it could mean True if all elements are True, or True if the array has non-zero length, just to name three possibilities.

Since different users might have different needs and different assumptions, the NumPy developers refused to guess and instead decided to raise a ValueError whenever one tries to evaluate an array in boolean context. Applying and to two numpy arrays causes the two arrays to be evaluated in boolean context (by calling __bool__ in Python3 or __nonzero__ in Python2).

Your original code

mask = ((r["dt"] >= startdate) & (r["dt"] <= enddate))
selected = r[mask]

looks correct. However, if you do want and, then instead of a and b use (a-b).any() or (a-b).all().

if(!(child is IContainer))

is the only operator to go (there's no IsNot operator).

You can build an extension method that does it:

public static bool IsA<T>(this object obj) {
    return obj is T;
}

and then use it to:

if (!child.IsA<IContainer>())

And you could follow on your theme:

public static bool IsNotAFreaking<T>(this object obj) {
    return !(obj is T);
}

if (child.IsNotAFreaking<IContainer>()) { // ...

Update (considering the OP's code snippet):

Since you're actually casting the value afterward, you could just use as instead:

public void Update(DocumentPart part) {
    part.Update();
    IContainer containerPart = part as IContainer;
    if(containerPart == null) return;
    foreach(DocumentPart child in containerPart.Children) { // omit the cast.
       //...etc...

It happens because of not very straight forward Servlet specification. If you are working with a native HttpServletRequest implementation you cannot get both the URL encode body and the parameters. Spring does some workarounds, which make it even more strange and nontransparent.

In such cases Spring (version 3.2.4) re-renders a body for you using data from the getParameterMap() method. It mixes GET and POST parameters and breaks the parameter order. The class, which is responsible for the chaos is ServletServerHttpRequest. Unfortunately it cannot be replaced, but the class StringHttpMessageConverter can be.

The clean solution is unfortunately not simple:

1. Replacing StringHttpMessageConverter. Copy/Overwrite the original class adjusting method readInternal().
2. Wrapping HttpServletRequest overwriting getInputStream(), getReader() and getParameter*() methods.

In the method StringHttpMessageConverter#readInternal following code must be used:

    if (inputMessage instanceof ServletServerHttpRequest) {
        ServletServerHttpRequest oo = (ServletServerHttpRequest)inputMessage;
        input = oo.getServletRequest().getInputStream();
    } else {
        input = inputMessage.getBody();
    }

Then the converter must be registered in the context.

<mvc:annotation-driven>
    <mvc:message-converters register-defaults="true/false">
        <bean class="my-new-converter-class"/>
   </mvc:message-converters>
</mvc:annotation-driven>

The step two is described here: Http Servlet request lose params from POST body after read it once

Yay recursion!

def trunc(s,l):
    if l > 0:
        return s[:l] + trunc(s, l - len(s))
    return ''

Won't scale forever, but it's fine for smaller strings. And it's pretty.

I admit I just read the Little Schemer and I like recursion right now.

You can now do this in most "modern" browsers!

Here is the original article I read (posted July 10, 2010): HTML5: Changing the browser-URL without refreshing page.

For a more in-depth look into pushState/replaceState/popstate (aka the HTML5 History API) see the MDN docs.

TL;DR, you can do this:

window.history.pushState("object or string", "Title", "/new-url");

See my answer to Modify the URL without reloading the page for a basic how-to.

And there is:

function character_count(string, char, ptr = 0, count = 0) {
    while (ptr = string.indexOf(char, ptr) + 1) {count ++}
    return count
}

Works with integers too!

The answers given here already may work in limited situations, but are certainly not the best way to go about it. Don't reinvent the wheel. The File System Object in the Microsoft Scripting Runtime library already has a method to do exactly this. It's called GetBaseName. It handles periods in the file name as is.

You can define a Error.prototype.toJSON to retrieve a plain Object representing the Error:

if (!('toJSON' in Error.prototype))
Object.defineProperty(Error.prototype, 'toJSON', {
    value: function () {
        var alt = {};

        Object.getOwnPropertyNames(this).forEach(function (key) {
            alt[key] = this[key];
        }, this);

        return alt;
    },
    configurable: true,
    writable: true
});

var error = new Error('testing');
error.detail = 'foo bar';

console.log(JSON.stringify(error));
// {"message":"testing","detail":"foo bar"}

Using Object.defineProperty() adds toJSON without it being an enumerable property itself.

Regarding modifying Error.prototype, while toJSON() may not be defined for Errors specifically, the method is still standardized for objects in general (ref: step 3). So, the risk of collisions or conflicts is minimal.

Though, to still avoid it completely, JSON.stringify()'s replacer parameter can be used instead:

function replaceErrors(key, value) {
    if (value instanceof Error) {
        var error = {};

        Object.getOwnPropertyNames(value).forEach(function (key) {
            error[key] = value[key];
        });

        return error;
    }

    return value;
}

var error = new Error('testing');
error.detail = 'foo bar';

console.log(JSON.stringify(error, replaceErrors));

The verification of the certificate identity is performed against what the client requests.

When your client uses https://xxx.xxx.xxx.xxx/something (where xxx.xxx.xxx.xxx is an IP address), the certificate identity is checked against this IP address (in theory, only using an IP SAN extension).

If your certificate has no IP SAN, but DNS SANs (or if no DNS SAN, a Common Name in the Subject DN), you can get this to work by making your client use a URL with that host name instead (or a host name for which the cert would be valid, if there are multiple possible values). For example, if you cert has a name for www.example.com, use https://www.example.com/something.

Of course, you'll need that host name to resolve to that IP address.

In addition, if there are any DNS SANs, the CN in the Subject DN will be ignored, so use a name that matches one of the DNS SANs in this case.

In Java you would do something similar to:

Transport transport = session.getTransport("smtps");
transport.connect (smtp_host, smtp_port, smtp_username, smtp_password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();    

Note 'smtpS' protocol. Also socketFactory properties is no longer necessary in modern JVMs but you might need to set 'mail.smtps.auth' and 'mail.smtps.starttls.enable' to 'true' for Gmail. 'mail.smtps.debug' could be helpful too.

You can use any commonly available hash algorithm (eg. SHA-1), which will give you a slightly longer result than what you need. Simply truncate the result to the desired length, which may be good enough.

For example, in Python:

>>> import hashlib
>>> hash = hashlib.sha1("my message".encode("UTF-8")).hexdigest()
>>> hash
'104ab42f1193c336aa2cf08a2c946d5c6fd0fcdb'
>>> hash[:10]
'104ab42f11'

The scaling on your example figure is a bit strange but you can force it by plotting the index of each x-value and then setting the ticks to the data points:

import matplotlib.pyplot as plt
x = [0.00001,0.001,0.01,0.1,0.5,1,5]
# create an index for each tick position
xi = list(range(len(x)))
y = [0.945,0.885,0.893,0.9,0.996,1.25,1.19]
plt.ylim(0.8,1.4)
# plot the index for the x-values
plt.plot(xi, y, marker='o', linestyle='--', color='r', label='Square') 
plt.xlabel('x')
plt.ylabel('y') 
plt.xticks(xi, x)
plt.title('compare')
plt.legend() 
plt.show()

I use this method, that uses trim() to avoid blank spaces :

EditText myEditText = (EditText) findViewById(R.id.editUsername);
if ("".equals(myEditText.getText().toString().trim()) {
    Toast.makeText(this, "You did not enter a value!", Toast.LENGTH_LONG).show();
    return;
}

an example if you have several EditText´s

if (("".equals(edtUser.getText().toString().trim()) || "".equals(edtPassword.getText().toString().trim()))){
        Toast.makeText(this, "a value is missing!", Toast.LENGTH_LONG).show();
        return;

Chebyshev polynomials, as mentioned in another answer, are the polynomials where the largest difference between the function and the polynomial is as small as possible. That is an excellent start.

In some cases, the maximum error is not what you are interested in, but the maximum relative error. For example for the sine function, the error near x = 0 should be much smaller than for larger values; you want a small relative error. So you would calculate the Chebyshev polynomial for sin x / x, and multiply that polynomial by x.

Next you have to figure out how to evaluate the polynomial. You want to evaluate it in such a way that the intermediate values are small and therefore rounding errors are small. Otherwise the rounding errors might become a lot larger than errors in the polynomial. And with functions like the sine function, if you are careless then it may be possible that the result that you calculate for sin x is greater than the result for sin y even when x < y. So careful choice of the calculation order and calculation of upper bounds for the rounding error are needed.

For example, sin x = x - x^3/6 + x^5 / 120 - x^7 / 5040... If you calculate naively sin x = x * (1 - x^2/6 + x^4/120 - x^6/5040...), then that function in parentheses is decreasing, and it will happen that if y is the next larger number to x, then sometimes sin y will be smaller than sin x. Instead, calculate sin x = x - x^3 * (1/6 - x^2 / 120 + x^4/5040...) where this cannot happen.

When calculating Chebyshev polynomials, you usually need to round the coefficients to double precision, for example. But while a Chebyshev polynomial is optimal, the Chebyshev polynomial with coefficients rounded to double precision is not the optimal polynomial with double precision coefficients!

For example for sin (x), where you need coefficients for x, x^3, x^5, x^7 etc. you do the following: Calculate the best approximation of sin x with a polynomial (ax + bx^3 + cx^5 + dx^7) with higher than double precision, then round a to double precision, giving A. The difference between a and A would be quite large. Now calculate the best approximation of (sin x - Ax) with a polynomial (b x^3 + cx^5 + dx^7). You get different coefficients, because they adapt to the difference between a and A. Round b to double precision B. Then approximate (sin x - Ax - Bx^3) with a polynomial cx^5 + dx^7 and so on. You will get a polynomial that is almost as good as the original Chebyshev polynomial, but much better than Chebyshev rounded to double precision.

Next you should take into account the rounding errors in the choice of polynomial. You found a polynomial with minimum error in the polynomial ignoring rounding error, but you want to optimise polynomial plus rounding error. Once you have the Chebyshev polynomial, you can calculate bounds for the rounding error. Say f (x) is your function, P (x) is the polynomial, and E (x) is the rounding error. You don't want to optimise | f (x) - P (x) |, you want to optimise | f (x) - P (x) +/- E (x) |. You will get a slightly different polynomial that tries to keep the polynomial errors down where the rounding error is large, and relaxes the polynomial errors a bit where the rounding error is small.

All this will get you easily rounding errors of at most 0.55 times the last bit, where +,-,*,/ have rounding errors of at most 0.50 times the last bit.

Let's say for instance you want to get a list of all your customers:

var customers = context.Customers.ToList();

And let's assume that each Customer object has a reference to its set of Orders, and that each Order has references to LineItems which may also reference a Product.

As you can see, selecting a top-level object with many related entities could result in a query that needs to pull in data from many sources. As a performance measure, Include() allows you to indicate which related entities should be read from the database as part of the same query.

Using the same example, this might bring in all of the related order headers, but none of the other records:

var customersWithOrderDetail = context.Customers.Include("Orders").ToList();

As a final point since you asked for SQL, the first statement without Include() could generate a simple statement:

SELECT * FROM Customers;

The final statement which calls Include("Orders") may look like this:

SELECT *
FROM Customers JOIN Orders ON Customers.Id = Orders.CustomerId;

I'm using Conda on Windows and this answer did not work for me. But I can suggest another solution:

• rename enviroment folder (old_name to new_name)

• open shell and activate env with custom folder:

  conda.bat activate "C:\Users\USER_NAME\Miniconda3\envs\new_name"

• now you can use this enviroment, but it's not on the enviroment list. Update\install\remove any package to fix it. For example, update numpy:

  conda update numpy

• after applying any action to package, the environment will show in env list. To check this, type:

  conda env list

Put this code in a Module in VBA (Developer Tab -> Visual Basic)

Dim TimerActive As Boolean
Sub StartTimer()
    Start_Timer
End Sub
Private Sub Start_Timer()
    TimerActive = True
    Application.OnTime Now() + TimeValue("00:01:00"), "Timer"
End Sub
Private Sub Stop_Timer()
    TimerActive = False
End Sub
Private Sub Timer()
    If TimerActive Then
        ActiveSheet.Cells(1, 1).Value = Time
        Application.OnTime Now() + TimeValue("00:01:00"), "Timer"
    End If
End Sub

You can invoke the "StartTimer" function when the workbook opens and have it repeat every minute by adding the below code to your workbooks Visual Basic "This.Workbook" class in the Visual Basic editor.

Private Sub Workbook_Open()
    Module1.StartTimer
End Sub

Now, every time 1 minute passes the Timer procedure will be invoked, and set cell A1 equal to the current time.

Answers above elucidated many things, but I think it is useful to make a conceptual distinction.

What if you take a perfectly on-focus picture of a blurred image?

The blurring detection problem is only well posed when you have a reference. If you need to design, e.g., an auto-focus system, you compare a sequence of images taken with different degrees of blurring, or smoothing, and you try to find the point of minimum blurring within this set. I other words you need to cross reference the various images using one of the techniques illustrated above (basically--with various possible levels of refinement in the approach--looking for the one image with the highest high-frequency content).
