I made it short way like this (Working on API pre 21 as well as post 21)

Your radio button in xml should look like this

  <RadioButton android:id="@+id/radioid"                    
                android:layout_height="wrap_content"
                android:layout_width="wrap_content"                 
                android:button="@drawable/radiodraw" />

in radiodraw.xml

  <?xml version="1.0" encoding="utf-8"?>
  <selector xmlns:android="http://schemas.android.com/apk/res/android">    
      <item android:state_checked="false" >
          <shape  android:shape="oval" >
              <stroke android:width="1dp" android:color="#000"/>
              <size android:width="30dp" android:height="30dp"/>
              <solid android:color="@android:color/transparent"/>
          </shape>
      </item>
      <item android:state_checked="true">
          <layer-list>
              <item>
                  <shape android:shape="oval">
                      <stroke android:width="1dp" android:color="#000"/>
                      <size android:width="30dp" android:height="30dp"/>
                      <solid android:color="@android:color/transparent"/>
                  </shape>
              </item>
              <item android:top="5dp" android:bottom="5dp" android:left="5dp" android:right="5dp">
                  <shape android:shape="oval">
                      <solid android:width="1dp" android:color="#000"/>
                      <size android:width="10dp" android:height="10dp"/>
                  </shape>
              </item>
          </layer-list>
      </item>
  </selector>

have to add color transparent for drawing the unchecked status ;else it draw solid black oval.

Make a list of items, based on their weights:

items = [1, 2, 3, 4, 5, 6]
probabilities= [0.1, 0.05, 0.05, 0.2, 0.4, 0.2]
# if the list of probs is normalized (sum(probs) == 1), omit this part
prob = sum(probabilities) # find sum of probs, to normalize them
c = (1.0)/prob # a multiplier to make a list of normalized probs
probabilities = map(lambda x: c*x, probabilities)
print probabilities

ml = max(probabilities, key=lambda x: len(str(x)) - str(x).find('.'))
ml = len(str(ml)) - str(ml).find('.') -1
amounts = [ int(x*(10**ml)) for x in probabilities]
itemsList = list()
for i in range(0, len(items)): # iterate through original items
  itemsList += items[i:i+1]*amounts[i]

# choose from itemsList randomly
print itemsList

An optimization may be to normalize amounts by the greatest common divisor, to make the target list smaller.

Also, this might be interesting.

Hmm, there are many solution written for php version lower than 7.1.

Here is an other simple one for those who doesn't want catch all exception and can't make common interfaces:

<?php
$ex = NULL
try {
    /* ... */
} catch (FirstException $ex) {
    // just do nothing here
} catch (SecondException $ex) {
    // just do nothing here
}
if ($ex !== NULL) {
    // handle those exceptions here!
}
?>

As indicated a standard ipv6 address is at most 45 chars, but an ipv6 address can also include an ending % followed by a "scope" or "zone" string, which has no fixed length but is generally a small positive integer or a network interface name, so in reality it can be bigger than 45 characters. Network interface names are typically "eth0", "eth1", "wlan0", so choosing 50 as the limit is likely good enough.

You can get the formdata as string:

    protected NameValueCollection GetFormData()
    {
        string root = HttpContext.Current.Server.MapPath("~/App_Data");
        var provider = new MultipartFormDataStreamProvider(root);

        Request.Content.ReadAsMultipartAsync(provider);

        return provider.FormData;
    }

    [HttpPost]
    public void test() 
    {
        var formData = GetFormData();
        var userId = formData["userId"];

        // todo json stuff
    }

https://docs.microsoft.com/en-us/aspnet/web-api/overview/advanced/sending-html-form-data-part-2

You should not throw an ArithmeticException. Since the error is in the supplied arguments, throw an IllegalArgumentException. As the documentation says:

Thrown to indicate that a method has been passed an illegal or inappropriate argument.

Which is exactly what is going on here.

if (divisor == 0) {
    throw new IllegalArgumentException("Argument 'divisor' is 0");
}

This question is tagged with PHP. But many people are using Laravel framework now. It might help somebody in future. That's why I answering for Laravel. It's more easy to encrypt and decrypt with internal functions.

$string = 'c4ca4238a0b923820dcc';
$encrypted = \Illuminate\Support\Facades\Crypt::encrypt($string);
$decrypted_string = \Illuminate\Support\Facades\Crypt::decrypt($encrypted);

var_dump($string);
var_dump($encrypted);
var_dump($decrypted_string);

Note: Be sure to set a 16, 24, or 32 character random string in the key option of the config/app.php file. Otherwise, encrypted values will not be secure.

But you should not use encrypt and decrypt for authentication. Rather you should use hash make and check.

To store password in database, make hash of password and then save.

$password = Input::get('password_from_user'); 
$hashed = Hash::make($password); // save $hashed value

To verify password, get password stored of account from database

// $user is database object
// $inputs is Input from user
if( \Illuminate\Support\Facades\Hash::check( $inputs['password'], $user['password']) == false) {
  // Password is not matching 
} else {
  // Password is matching 
}

Use aapt from the SDK like

aapt dump badging yourpkg.apk

This will print the package name together with other info.

the tools is located in
<sdk_home>/build-tools/android-<api_level>
or
<sdk_home>/platform-tools
or
<sdk_home>/platforms/android-<api_level>/tools

Updated according to geniusburger's comment. Thanks!

Perhaps am late or maybe you've already used it before but there is another one called ksoap and its pretty amazing.. It also includes timeouts and can parse any SOAP based webservice efficiently. I also made a few changes to suit my parsing.. Look it up

Your query does not work because you have no FROM clause that specifies the tables you are aliasing via A/B.

Please try using the following:

UPDATE A
    SET A.NAME = B.NAME
FROM TableNameA A, TableNameB B
WHERE A.ID = B.ID

Personally I prefer to use more explicit join syntax for clarity i.e.

UPDATE A
    SET A.NAME = B.NAME
FROM TableNameA A
    INNER JOIN TableName B ON 
        A.ID = B.ID

Here is complete console working application code. Please install RestSharp package.

using RestSharp;
using System;

namespace RESTSharpClient
{
    class Program
    {
        static void Main(string[] args)
        {
        string url = "https://abc.example.com/";
        string jsonString = "{" +
                "\"auth\": {" +
                    "\"type\" : \"basic\"," +
                    "\"password\": \"@P&p@y_10364\"," +
                    "\"username\": \"prop_apiuser\"" +
                "}," +
                "\"requestId\" : 15," +
                "\"method\": {" +
                    "\"name\": \"getProperties\"," +
                    "\"params\": {" +
                        "\"showAllStatus\" : \"0\"" +
                    "}" +
                "}" +
            "}";

        IRestClient client = new RestClient(url);
        IRestRequest request = new RestRequest("api/properties", Method.POST, DataFormat.Json);
        request.AddHeader("Content-Type", "application/json; CHARSET=UTF-8");
        request.AddJsonBody(jsonString);

        var response = client.Execute(request);
        Console.WriteLine(response.Content);
        //TODO: do what you want to do with response.
    }
  }
}

This is what worked for me

    function showErrorMessage(xhr, status, error) {
        if (xhr.responseText != "") {

            var jsonResponseText = $.parseJSON(xhr.responseText);
            var jsonResponseStatus = '';
            var message = '';
            $.each(jsonResponseText, function(name, val) {
                if (name == "ResponseStatus") {
                    jsonResponseStatus = $.parseJSON(JSON.stringify(val));
                     $.each(jsonResponseStatus, function(name2, val2) {
                         if (name2 == "Message") {
                             message = val2;
                         }
                     });
                }
            });

            alert(message);
        }
    }

There is no DATEDIFF() function in Oracle. On Oracle, it is an arithmetic issue

select DATE1-DATE2 from table 

file version < 5 : file -i -b /path/to/file
file version >=5 : file --mime-type -b /path/to/file

If you just want to extract something from existing commit and keep the original one, you can use

git reset --patch HEAD^

instead of git reset HEAD^. This command allows you to reset just chunks you need.

After you chose the chunks you want to reset, you'll have staged chunks that will reset changes in previous commit after you do

git commit --amend --no-edit

and unstaged chunks that you can add to the separate commit by

git add .
git commit -m "new commit"

Off topic fact:

In mercurial they have hg split - the second feature after hg absorb I'd like to see in git.

Generally speaking, a software product isn't your "property already", as you said in the comment. Most of the times (I won't be irresponsible to say anything in open), it's licensed to you. A license to use some thing is not the same thing as owning (property rights) that very same thing.

That's because there are authorship, copyright, intellectual property rights applicable to it. I don't know how things work in United States (or in your country), but it's generally accepted that the work of a mind, a creative work, must not be changed in its nature as such to make the expression of art to be different than that expression that the author intended. That applies for example, in some cases, to architectural work (in most countries, you can't change the appearance of a building to "desfigure" the work of art of the architect, without his prior consent). Exceptions are made, obviously, when the author expressly authorizes such changes (e.g., Creative Commons licenses, open source licenses etc.).

Anyway, that's why you see in most EULAs the typical sentence: "this software is licensed, not sold". That's the purpose and reason why.

Now that you understand the reasons why you can't wander around changing other people's art, let me be technical.

There are possible ways to decompile Java programs. You can use dex2jar, it provides a somewhat good start for you to start looking for things and changes. And perhaps rebuild the code by mounting back the pieces together. Good luck, as most people obfuscate their codes to make that harder.

However, let me say that it's still forbidden to change programs, as I said above. And it's extremely unethical. It makes me sad that people do that with no scruples (not saying it's your case, just warning you). It shouldn't need people to be at the other side to understand that. Or maybe that's just me, who lives in a country where piracy is rampant.

The tools are always out there. But the conscience, unfortunately, not always.

edit: in case it isn't clear enough already, I do NOT approve the use of these programs. I use them myself to check how hard my own applications are to be reverse engineered. But I also think that explaning is always better than denial (better be here).

Its Simple!

Take example of television - it is Encapsulation, because:

1. Television is loaded with different functionalies that i don't know because they are completely hidden.

2. Hidden things like music, video etc everything bundled in a capsule that what we call a TV

Now, Abstraction is When we know a little about something and which can help us to manipulate something for which we don't know how it works internally.

For eg: A remote-control for TV is abstraction, because

1. With remote we know that pressing the number keys will change the channels. We are not aware as to what actually happens internally. We can manipulate the hidden thing but we don't know how it is being done internally.

Programmatically, when we can acess the hidden data somehow and know something.. is Abstraction .. And when we know nothing about the internals its Encapsulation.

Without remote we can't change anything on TV we have to see what it shows coz all controls are hidden.

You can use the display property of style. Intialy set the result section style as

style = "display:none"

Then the div will not be visible and there won't be any white space.

Once the search results are being populated change the display property using the java script like

document.getElementById("someObj").style.display = "block"

Using java script you can make the div invisible

document.getElementById("someObj").style.display = "none"

Try going to "Manage Jenkins"->"Manage Users" go to the specific user, edit his/her configuration "My Views section" default view.

As already mentioned by several people, eq is the right operator here.

If you use warnings; in your script, you'll get warnings about this (and many other useful things); I'd recommend use strict; as well.

I've been able to do this using SVG filter. You can write a filter that multiplies the color of source image with the color you want to change to. In the code snippet below, flood-color is the color we want to change image color to (which is Red in this case.) feComposite tells the filter how we're processing the color. The formula for feComposite with arithmetic is (k1*i1*i2 + k2*i1 + k3*i2 + k4) where i1 and i2 are input colors for in/in2 accordingly. So specifying only k1=1 means it will do just i1*i2, which means multiplying both input colors together.

Note: This only works with HTML5 since this is using inline SVG. But I think you might be able to make this work with older browser by putting SVG in a separate file. I haven't tried that approach yet.

Here's the snippet:

Salvaging (and extending) the list from an old version of the Wikipedia page:

Documentation

• Primer
• Cheat Sheet
• Quick Reference

Implementations

Although the reference implementation of reStructuredText is written in Python, there are reStructuredText parsers in other languages too.

Python - Docutils

The main distribution of reStructuredText is the Python Docutils package. It contains several conversion tools:

• rst2html - from reStructuredText to HTML
• rst2xml - from reStructuredText to XML
• rst2latex - from reStructuredText to LaTeX
• rst2odt - from reStructuredText to ODF Text (word processor) document.
• rst2s5 - from reStructuredText to S5, a Simple Standards-based Slide Show System
• rst2man - from reStructuredText to Man page

Haskell - Pandoc

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read Markdown and (subsets of) reStructuredText, HTML, and LaTeX, and it can write Markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff man pages, and S5 HTML slide shows.

There is an Pandoc online tool (POT) to try this library. Unfortunately, compared to the reStructuredText online renderer (ROR),

• POT truncates input rather more shortly. The POT user must render input in chunks that could be rendered whole by the ROR.
• POT output lacks the helpful error messages displayed by the ROR (and generated by docutils)

Java - JRst

JRst is a Java reStructuredText parser. It can currently output HTML, XHTML, DocBook xdoc and PDF, BUT seems to have serious problems: neither PDF or (X)HTML generation works using the current full download, result pages in (X)HTML are empty and PDF generation fails on IO problems with XSL files (not bundled??). Note that the original JRst has been removed from the website; a fork is found on GitHub.

Scala - Laika

Laika is a new library for transforming markup languages to other output formats. Currently it supports input from Markdown and reStructuredText and produce HTML output. The library is written in Scala but should be also usable from Java.

Perl

• Text::Restructured - Perl implementation of reStructuredText parser
• Dotiac::DTL::Addon::markup - Filters to work with common markup languages - support reStructuredText
• Pod::POM::View::Restructured - View for Pod::POM that outputs reStructuredText

PHP

• Gregwar/RST - A mature PHP5.3 parser with tests
• php-restructuredtext - A simple, incomplete (but functional) implementation

C#/.NET

• reStructuredText for ANTLR - A C# based parser with tests (in progress). It also provides the language server behind reStructuredText extension for Visual Studio Code.

Nim/C

The Nim compiler features the commands rst2htmland rst2tex which transform reStructuredText files to HTML and TeX files. The standard library provides the following modules (used by the compiler) to handle reStructuredText files programmatically:

• rst - implements a reStructuredText parser
• rstast - implements an AST for the reStructuredText parser
• rstgen - implements a generator of HTML/Latex from reStructuredText

Other 3rd party converters

Most (but not all) of these tools are based on Docutils (see above) and provide conversion to or from formats that might not be supported by the main distribution.

From reStructuredText

• restview - This pip-installable python package requires docutils, which does the actual rendering. restview's major ease-of-use feature is that, when you save changes to your document(s), it automagically re-renders and re-displays them. restview
  1. starts a small web server
  2. calls docutils to render your document(s) to HTML
  3. calls your device's browser to display the output HTML.
• rst2pdf - from reStructuredText to PDF
• rst2odp - from reStructuredText to ODF Presentation
• rst2beamer - from reStructuredText to LaTeX beamer Presentation class
• Wikir - from reStructuredText to a Google (and possibly other) Wiki formats
• rst2qhc - Convert a collection of reStructuredText files into a Qt (toolkit) Help file and (optional) a Qt Help Project file

To reStructuredText

• xml2rst is an XSLT script to convert Docutils internal XML representation (back) to reStructuredText
• Pandoc (see above) can also convert from Markdown, HTML and LaTeX to reStructuredText
• db2rst is a simple and limited DocBook to reStructuredText translator
• pod2rst - convert .pod files to reStructuredText files

Extensions

Some projects use reStructuredText as a baseline to build on, or provide extra functionality extending the utility of the reStructuredText tools.

Sphinx

The Sphinx documentation generator translates a set of reStructuredText source files into various output formats, automatically producing cross-references, indices etc.

rest2web

rest2web is a simple tool that lets you build your website from a single template (or as many as you want), and keep the contents in reStructuredText.

Pygments

Pygments is a generic syntax highlighter for general use in all kinds of software such as forum systems, Wikis or other applications that need to prettify source code. See Using Pygments in reStructuredText documents.

Free Editors

While any plain text editor is suitable to write reStructuredText documents, some editors have better support than others.

Emacs

The Emacs support via rst-mode comes as part of the Docutils package under /docutils/tools/editors/emacs/rst.el

Vim

The vim-common package for that comes with most GNU/Linux distributions has reStructuredText syntax highlight and indentation support of reStructuredText out of the box:

• reStructuredText syntax highlighting mode for vim
• VST (Vim reStructured Text) is a plugin for Vim7 with folding for reStructuredText
• Riv.vim - fresh vim plugin for authoring rst and Sphinx doc
• Previm: Vim plugin for live previewing of reStructuredText and other mark up documents

Jed

There is a rst mode for the Jed programmers editor.

gedit

gedit, the official text editor of the GNOME desktop environment. There is a gedit reStructuredText plugin.

Geany

Geany, a small and lightweight Integrated Development Environment include support for reStructuredText from version 0.12 (October 10, 2007).

Leo

Leo, an outlining editor for programmers, supports reStructuredText via rst-plugin or via "@auto-rst" nodes (it's not well-documented, but @auto-rst nodes allow editing rst files directly, parsing the structure into the Leo outline).

It also provides a way to preview the resulting HTML, in a "viewrendered" pane.

FTE

The FTE Folding Text Editor - a free (licensed under the GNU GPL) text editor for developers. FTE has a mode for reStructuredText support. It provides color highlighting of basic RSTX elements and special menu that provide easy way to insert most popular RSTX elements to a document.

PyK

PyK is a successor of PyEdit and reStInPeace, written in Python with the help of the Qt4 toolkit.

Eclipse

The Eclipse IDE with the ReST Editor plug-in provides support for editing reStructuredText files.

NoTex

NoTex is a browser based (general purpose) text editor, with integrated project management and syntax highlighting. Plus it enables to write books, reports, articles etc. using rST and convert them to LaTex, PDF or HTML. The PDF files are of high publication quality and are produced via Sphinx with the Texlive LaTex suite.

Notepad++

Notepad++ is a general purpose text editor for Windows. It has syntax highlighting for many languages built-in and support for reStructuredText via a user defined language for reStructuredText.

Visual Studio Code

Visual Studio Code is a general purpose text editor for Windows/macOS/Linux. It has syntax highlighting for many languages built-in and supports reStructuredText via an extension from LeXtudio.

Dedicated reStructuredText Editors

• ReSTedit by Dinu Gherman and Bill Bumgarner
• Rest in Peace
• Enthought Tool Suite editor
• ReText a cross platform program that works like Marked.
• RSTPad a standalone cross-platform editor with live preview

Proprietary editors

Sublime Text

Sublime Text is a completely customizable and extensible source code editor available for Windows, OS X, and Linux. Registration is required for long-term use, but all functions are available in the unregistered version, with occasional reminders to purchase a license. Versions 2 and 3 (currently in beta) support reStructuredText syntax highlighting by default, and several plugins are available through the package manager Package Control to provide snippets and code completion, additional syntax highlighting, conversion to/from RST and other formats, and HTML preview in the browser.

BBEdit / TextWrangler

BBEdit (and its free variant TextWrangler) for Mac can syntax-highlight reStructuredText using this codeless language module.

TextMate

TextMate, a proprietary general-purpose GUI text editor for Mac OS X, has a bundle for reStructuredText.

Intype

Intype is a proprietary text editor for Windows, that support reStructuredText out of the box.

E Text Editor

E is a proprietary Text Editor licensed under the "Open Company License". It supports TextMate's bundles, so it should support reStructuredText the same way TextMate does.

PyCharm

PyCharm (and other IntelliJ platform IDEs?) has ReST/Sphinx support (syntax highlighting, autocomplete and preview).)

Wiki

here are some Wiki programs that support the reStructuredText markup as the native markup syntax, or as an add-on:

MediaWiki

MediaWiki reStructuredText extension allows for reStructuredText markup in MediaWiki surrounded by <rst> and </rst>.

MoinMoin

MoinMoin is an advanced, easy to use and extensible WikiEngine with a large community of users. Said in a few words, it is about collaboration on easily editable web pages.

There is a reStructuredText Parser for MoinMoin.

Trac

Trac is an enhanced wiki and issue tracking system for software development projects. There is a reStructuredText Support in Trac.

This Wiki

This Wiki is a Webware for Python Wiki written by Ian Bicking. This wiki uses ReStructuredText for its markup.

rstiki

rstiki is a minimalist single-file personal wiki using reStructuredText syntax (via docutils) inspired by pwyky. It does not support authorship indication, versioning, hierarchy, chrome/framing/templating or styling. It leverages docutils/reStructuredText as the wiki syntax. As such, it's under 200 lines of code, and in a single file. You put it in a directory and it runs.

ikiwiki

Ikiwiki is a wiki compiler. It converts wiki pages into HTML pages suitable for publishing on a website. Ikiwiki stores pages and history in a revision control system such as Subversion or Git. There are many other features, including support for blogging, as well as a large array of plugins. It's reStructuredText plugin, however is somewhat limited and is not recommended as its' main markup language at this time.

You can do this with a Correlated Subquery (That is a subquery wherein you reference a field in the main query). In this case:

SELECT * 
FROM yourtable t1
WHERE date = (SELECT max(date) from yourtable WHERE id = t1.id)

Here we give the yourtable table an alias of t1 and then use that alias in the subquery grabbing the max(date) from the same table yourtable for that id.

According to the Apple doc below, device token can not be decoded. So, I think the best thing to do is just leave it be.

https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/APNSOverview.html

Security Architecture

A device token is an opaque NSData instance that contains a unique identifier assigned by Apple to a specific app on a specific device. Only APNs can decode and read the contents of a device token. Each app instance receives its unique device token when it registers with APNs, and must then forward the token to its provider, as described in Configuring Remote Notification Support. The provider must include the device token in each push notification request that targets the associated device; APNs uses the device token to ensure the notification is delivered only to the unique app-device combination for which it is intended.

Git 2.22 (Q2 2019) introduces trace2 with commit ee4512e by Jeff Hostetler:

trace2: create new combined trace facility

Create a new unified tracing facility for git.
The eventual intent is to replace the current trace_printf* and trace_performance* routines with a unified set of git_trace2* routines.

In addition to the usual printf-style API, trace2 provides higer-level event verbs with fixed-fields allowing structured data to be written.
This makes post-processing and analysis easier for external tools.

Trace2 defines 3 output targets.
These are set using the environment variables "GIT_TR2", "GIT_TR2_PERF", and "GIT_TR2_EVENT".
These may be set to "1" or to an absolute pathname (just like the current GIT_TRACE).

Note: regarding environment variable name, always use GIT_TRACExxx, not GIT_TRxxx.
So actually GIT_TRACE2, GIT_TRACE2_PERF or GIT_TRACE2_EVENT.
See the Git 2.22 rename mentioned later below.

What follows is the initial work on this new tracing feature, with the old environment variable names:

• GIT_TR2 is intended to be a replacement for GIT_TRACE and logs command summary data.

• GIT_TR2_PERF is intended as a replacement for GIT_TRACE_PERFORMANCE.
  It extends the output with columns for the command process, thread, repo, absolute and relative elapsed times.
  It reports events for child process start/stop, thread start/stop, and per-thread function nesting.

• GIT_TR2_EVENT is a new structured format. It writes event data as a series of JSON records.

Calls to trace2 functions log to any of the 3 output targets enabled without the need to call different trace_printf* or trace_performance* routines.

See commit a4d3a28 (21 Mar 2019) by Josh Steadmon (steadmon).
^{(Merged by Junio C Hamano -- gitster -- in commit 1b40314, 08 May 2019)}

trace2: write to directory targets

When the value of a trace2 environment variable is an absolute path referring to an existing directory, write output to files (one per process) underneath the given directory.
Files will be named according to the final component of the trace2 SID, followed by a counter to avoid potential collisions.

This makes it more convenient to collect traces for every git invocation by unconditionally setting the relevant trace2 envvar to a constant directory name.

See also commit f672dee (29 Apr 2019), and commit 81567ca, commit 08881b9, commit bad229a, commit 26c6f25, commit bce9db6, commit 800a7f9, commit a7bc01e, commit 39f4317, commit a089724, commit 1703751 (15 Apr 2019) by Jeff Hostetler (jeffhostetler).

The new documentation now includes config settings which are only read from the system and global config files (meaning repository local and worktree config files and -c command line arguments are not respected.)

Example:

$ git config --global trace2.normalTarget ~/log.normal
$ git version
git version 2.20.1.155.g426c96fcdb

yields

$ cat ~/log.normal
12:28:42.620009 common-main.c:38                  version 2.20.1.155.g426c96fcdb

12:28:42.621101 git.c:432                         cmd_name version (version)
12:28:42.621215 git.c:662                         exit elapsed:0.001227 code:0
12:28:42.621250 trace2/tr2_tgt_normal.c:124 atexit elapsed:0.001265 code:0

And for performance measure:

$ git config --global trace2.perfTarget ~/log.perf
$ git version
git version 2.20.1.155.g426c96fcdb

yields

$ cat ~/log.perf

trace2: rename environment variables to GIT_TRACE2*

For an environment variable that is supposed to be set by users, the GIT_TR2* env vars are just too unclear, inconsistent, and ugly.

Most of the established GIT_* environment variables don't use abbreviations, and in case of the few that do (GIT_DIR, GIT_COMMON_DIR, GIT_DIFF_OPTS) it's quite obvious what the abbreviations (DIR and OPTS) stand for.
But what does TR stand for? Track, traditional, trailer, transaction, transfer, transformation, transition, translation, transplant, transport, traversal, tree, trigger, truncate, trust, or ...?!

The trace2 facility, as the '2' suffix in its name suggests, is supposed to eventually supercede Git's original trace facility.
It's reasonable to expect that the corresponding environment variables follow suit, and after the original GIT_TRACE variables they are called GIT_TRACE2; there is no such thing is 'GIT_TR'.

All trace2-specific config variables are, very sensibly, in the 'trace2' section, not in 'tr2'.

OTOH, we don't gain anything at all by omitting the last three characters of "trace" from the names of these environment variables.

So let's rename all GIT_TR2* environment variables to GIT_TRACE2*, before they make their way into a stable release.

Git 2.24 (Q3 2019) improves the Git repository initialization.

^{(Merged by Junio C Hamano -- gitster -- in commit b4a1eec, 09 Sep 2019)}

common-main: delay trace2 initialization

We initialize the trace2 system in the common main() function so that all programs (even ones that aren't builtins) will enable tracing.

But trace2 startup is relatively heavy-weight, as we have to actually read on-disk config to decide whether to trace.
This can cause unexpected interactions with other common-main initialization. For instance, we'll end up in the config code before calling initialize_the_repository(), and the usual invariant that the_repository is never NULL will not hold.

Let's push the trace2 initialization further down in common-main, to just before we execute cmd_main().

Git 2.24 (Q4 2019) makes also sure that output from trace2 subsystem is formatted more prettily now.

See commit 742ed63, commit e344305, commit c2b890a (09 Aug 2019), commit ad43e37, commit 04f10d3, commit da4589c (08 Aug 2019), and commit 371df1b (31 Jul 2019) by Jeff Hostetler (jeffhostetler).

trace2: discard new traces if target directory has too many files

^{Signed-off-by: Josh Steadmon}

trace2 can write files into a target directory.
With heavy usage, this directory can fill up with files, causing difficulty for trace-processing systems.

This patch adds a config option (trace2.maxFiles) to set a maximum number of files that trace2 will write to a target directory.

The following behavior is enabled when the maxFiles is set to a positive integer:

• When trace2 would write a file to a target directory, first check whether or not the traces should be discarded.
  Traces should be discarded if:
  • there is a sentinel file declaring that there are too many files
  • OR, the number of files exceeds trace2.maxFiles.
    In the latter case, we create a sentinel file named git-trace2-discard to speed up future checks.

The assumption is that a separate trace-processing system is dealing with the generated traces; once it processes and removes the sentinel file, it should be safe to generate new trace files again.

The default value for trace2.maxFiles is zero, which disables the file count check.

The config can also be overridden with a new environment variable: GIT_TRACE2_MAX_FILES.

And Git 2.24 (Q4 2019) teach trace2 about git push stages.

^{Signed-off-by: Heba Waly}

Move the functions documentation from Documentation/technical/api-trace2.txt to trace2.h as it's easier for the developers to find the usage information beside the code instead of looking for it in another doc file.

Only the functions documentation section is removed from Documentation/technical/api-trace2.txt as the file is full of details that seemed more appropriate to be in a separate doc file as it is, with a link to the doc file added in the trace2.h. Also the functions doc is removed to avoid having redundandt info which will be hard to keep syncronized with the documentation in the header file.

trace2: teach Git to log environment variables

^{Signed-off-by: Josh Steadmon
Acked-by: Jeff Hostetler}

Via trace2, Git can already log interesting config parameters (see the trace2_cmd_list_config() function). However, this can grant an incomplete picture because many config parameters also allow overrides via environment variables.

To allow for more complete logs, we add a new trace2_cmd_list_env_vars() function and supporting implementation, modeled after the pre-existing config param logging implementation.

With Git 2.27 (Q2 2020), teach codepaths that show progress meter to also use the start_progress() and the stop_progress() calls as a "region" to be traced.

trace2: log progress time and throughput

^{Signed-off-by: Emily Shaffer}

Rather than teaching only one operation, like 'git fetch', how to write down throughput to traces, we can learn about a wide range of user operations that may seem slow by adding tooling to the progress library itself.

Operations which display progress are likely to be slow-running and the kind of thing we want to monitor for performance anyways.

By showing object counts and data transfer size, we should be able to make some derived measurements to ensure operations are scaling the way we expect.

And:

With Git 2.27 (Q2 2020), last-minute fix for our recent change to allow use of progress API as a traceable region.

See commit 3af029c (15 May 2020) by Derrick Stolee (derrickstolee).
^{(Merged by Junio C Hamano -- gitster -- in commit 85d6e28, 20 May 2020)}

progress: call trace2_region_leave() only after calling _enter()

^{Signed-off-by: Derrick Stolee}

A user of progress API calls start_progress() conditionally and depends on the display_progress() and stop_progress() functions to become no-op when start_progress() hasn't been called.

As we added a call to trace2_region_enter() to start_progress(), the calls to other trace2 API calls from the progress API functions must make sure that these trace2 calls are skipped when start_progress() hasn't been called on the progress struct.

Specifically, do not call trace2_region_leave() from stop_progress() when we haven't called start_progress(), which would have called the matching trace2_region_enter().

That last part is more robust with Git 2.29 (Q4 2020):

See commit ac900fd (10 Aug 2020) by Martin Ågren (none).
^{(Merged by Junio C Hamano -- gitster -- in commit e6ec620, 17 Aug 2020)}

progress: don't dereference before checking for NULL

^{Signed-off-by: Martin Ågren}

In stop_progress(), we're careful to check that p_progress is non-NULL before we dereference it, but by then we have already dereferenced it when calling finish_if_sparse(*p_progress).
And, for what it's worth, we'll go on to blindly dereference it again inside stop_progress_msg().

We could return early if we get a NULL-pointer, but let's go one step further and BUG instead.
The progress API handles NULL just fine, but that's the NULL-ness of *p_progress, e.g., when running with --no-progress.
If p_progress is NULL, chances are that's a mistake.
For symmetry, let's do the same check in stop_progress_msg(), too.

With Git 2.29 (Q4 2020), there is even more trace, this time in a Git development environment.

git now includes in its man page:

GIT_TRACE_REFS

Enables trace messages for operations on the ref database. See GIT_TRACE for available trace output options.

With Git 2.30 (Q1 2021), like die() and error(), a call to warning() will also trigger a trace2 event.

fcntl() or ioctl() are used to set the properties for file streams. When you use this function to make a socket non-blocking, function like accept(), recv() and etc, which are blocking in nature will return error and errno would be set to EWOULDBLOCK. You can poll file descriptor sets to poll on sockets.

Take a look at the PDOStatement.fetchAll method. You could also use fetch in an iterator pattern.

Code sample for fetchAll, from the PHP documentation:

<?php
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();

/* Fetch all of the remaining rows in the result set */
print("Fetch all of the remaining rows in the result set:\n");
$result = $sth->fetchAll(\PDO::FETCH_ASSOC);
print_r($result);

For everyone struggling with this issue, you simply need to upgrade your openssl installation. I'm running windows 10, installed the latest anaconda 64-bit and am getting this error when I try to install/upgrade anything with 'conda' or 'pip'. If I uninstall the 64-bit anaconda and install the 32-bit, it works fine. I had a 64-bit version of openssl for windows installed, version 1.1.0 something. I uninstalled that and installed the latest I could find from here: https://slproweb.com/products/Win32OpenSSL.html -- there is a 64-bit version of 1.1.1 on there that worked. Now I can install packages via pip and conda successfully. Hope this helps.

Not sure, but what I think you're looking for is to create a java.util.Date from a String, then convert that java.util.Date to a java.sql.Date.

try this:

private static java.sql.Date getCurrentDate(String date) {

    java.util.Date today;
    java.sql.Date rv = null;
    try {

        SimpleDateFormat format = new SimpleDateFormat("dd-MM-yyyy");
        today = format.parse(date);
        rv = new java.sql.Date(today.getTime());
        System.out.println(rv.getTime());

    } catch (Exception e) {
        System.out.println("Exception: " + e.getMessage());
    } finally {
        return rv;
    }

}    

Will return a java.sql.Date object for setDate();

The function above will print out a long value:

1375934400000

Maybe the problem only in your IDE encoding settings. Try to set UTF-8 everywhere:

What you want to do is get the absolute path of the script (available via ${BASH_SOURCE[0]}) and then use this to get the parent directory and cd to it at the beginning of the script.

#!/bin/bash
parent_path=$( cd "$(dirname "${BASH_SOURCE[0]}")" ; pwd -P )

cd "$parent_path"
cat ../some.text

This will make your shell script work independent of where you invoke it from. Each time you run it, it will be as if you were running ./cat.sh inside dir.

Note that this script only works if you're invoking the script directly (i.e. not via a symlink), otherwise the finding the current location of the script gets a little more tricky)

I wrote this pattern:

Pattern SPECIAL_REGEX_CHARS = Pattern.compile("[{}()\\[\\].+*?^$\\\\|]");

And use it in this method:

String escapeSpecialRegexChars(String str) {

    return SPECIAL_REGEX_CHARS.matcher(str).replaceAll("\\\\$0");
}

Then you can use it like this, for example:

Pattern toSafePattern(String text)
{
    return Pattern.compile(".*" + escapeSpecialRegexChars(text) + ".*");
}

We needed to do that because, after escaping, we add some regex expressions. If not, you can simply use \Q and \E:

Pattern toSafePattern(String text)
{
    return Pattern.compile(".*\\Q" + text + "\\E.*")
}

Currently there is no way to apply a css to get your desired result . Why not use libraries like choosen or select2 . These allow you to style the way you want.

If you don want to use third party libraries then you can make a simple un-ordered list and play with some css.Here is thread you could follow

If there is no possibility to remove or change path to a hard disc file using Virtual Media Manager (in my case) then:

1. Open '.vbox' and '.vbox-prev' (if exist) files in any text editor.
2. Edit 'location' attribute of the element 'HardDisk' to your path, for example: "d:/VM/VirtualBox/Win10/Win10.vmdk" (screenshot).

import csv

def read_cell(x, y):
    with open('file.csv', 'r') as f:
        reader = csv.reader(f)
        y_count = 0
        for n in reader:
            if y_count == y:
                cell = n[x]
                return cell
            y_count += 1

print (read_cell(4, 8)) 

This example prints cell 4, 8 in Python 3.

As noticed in comments start with sent_tokenize(), because word_tokenize() works only on a single sentence. You can filter out punctuation with filter(). And if you have an unicode strings make sure that is a unicode object (not a 'str' encoded with some encoding like 'utf-8').

from nltk.tokenize import word_tokenize, sent_tokenize

text = '''It is a blue, small, and extraordinary ball. Like no other'''
tokens = [word for sent in sent_tokenize(text) for word in word_tokenize(sent)]
print filter(lambda word: word not in ',-', tokens)

GLM has good example of rotation : http://glm.g-truc.net/code.html

glm::mat4 Projection = glm::perspective(45.0f, 4.0f / 3.0f, 0.1f, 100.f);
glm::mat4 ViewTranslate = glm::translate(
    glm::mat4(1.0f),
    glm::vec3(0.0f, 0.0f, -Translate)
);
glm::mat4 ViewRotateX = glm::rotate(
    ViewTranslate,
    Rotate.y,
    glm::vec3(-1.0f, 0.0f, 0.0f)
);
glm::mat4 View = glm::rotate(
    ViewRotateX,
    Rotate.x,
    glm::vec3(0.0f, 1.0f, 0.0f)
);
glm::mat4 Model = glm::scale(
    glm::mat4(1.0f),
    glm::vec3(0.5f)
);
glm::mat4 MVP = Projection * View * Model;
glUniformMatrix4fv(LocationMVP, 1, GL_FALSE, glm::value_ptr(MVP));

I am answering this old question just because it still shows up in google queries and I think one optimal answer is missing. Try this code: use ::before or ::after

See Align <hr> to the left in an HTML5-compliant way

this works:

window.onscroll = function (e) {  
// called when the window is scrolled.  
} 

edit:

you said this is a function in a TimeInterval..
Try doing it like so:

userHasScrolled = false;
window.onscroll = function (e)
{
    userHasScrolled = true;
}

then inside your Interval insert this:

if(userHasScrolled)
{
//do your code here
userHasScrolled = false;
}

left: initial

This will also set left back to the browser default.

But important to know property: initial is not supported in IE.

Use the 'And' keyword for a logical and. Like this:

If Not ((filename = testFileName) And (fileName <> "")) Then

In Swift 5,

let swipeGesture = UISwipeGestureRecognizer(target: self, action: #selector(handleSwipe))
swipeGesture.direction = [.left, .right, .up, .down]
view.addGestureRecognizer(swipeGesture)

From Visual Studio 2015 and onward, you need to go to the "Exception Settings" dialog (Ctrl+Alt+E) and check off the "Common Language Runtime Exceptions" (or a specific one you want i.e. ArgumentNullException) to make it break on handled exceptions.

Step 1 Step 2

Honestly, I hate all the solutions I've seen so far, and I'll tell you why: They just don't seem to ever align it right...so here's what I usually do:

I know what pixel values each div and their respective margins hold...so I do the following.

I'll create a wrapper div that has an absolute position and a left value of 50%...so this div now starts in the middle of the screen, and then I subtract half of all the content of the div's width...and I get BEAUTIFULLY scaling content...and I think this works across all browsers, too. Try it for yourself (this example assumes all content on your site is wrapped in a div tag that uses this wrapper class and all content in it is 200px in width):

.wrapper {
    position: absolute;
    left: 50%;
    margin-left: -100px;
}

EDIT: I forgot to add...you may also want to set width: 0px; on this wrapper div for some browsers to not show the scrollbars, and then you may use absolute positioning for all inner divs.

This also works AMAZING for vertically aligning your content as well using top: 50% and margin-top. Cheers!

I've just learned of a handy packaging tool called fpm recently. Stumbling upon this question I thought I might give it a try. Turns out, after reading @OrwellHindenberg's answer, it's easy to package maven into an RPM with fpm.

yum install -y gcc make rpm-build ruby-devel rubygems
gem install fpm

create a project directory and layout the directory structure of the package

mkdir maven-build
cd maven-build
mkdir -p etc/profile.d opt

create a file that we'll install to /etc/profile.d/maven.sh, we'll store this under the newly created etc/profile.d directory as maven.sh, with the following contents

export M3_HOME=/opt/apache-maven-3.1.0
export M3=$M3_HOME/bin
export PATH=$M3:$PATH

download and unpack the latest maven in the opt directory

wget http://www.eng.lsu.edu/mirrors/apache/maven/maven-3/3.1.0/binaries/apache-maven-3.1.0-bin.tar.gz
tar -xzf apache-maven-3.1.0-bin.tar.gz -C opt

finally, build the RPM

fpm -n maven-3.1.0 -s dir -t rpm etc opt

Now you can install maven through rpm

$ rpm -Uvh maven-3.1.0-1.0-1.x86_64.rpm 
Preparing...                ########################################### [100%]
   1:maven-3.1.0            ########################################### [100%]

and viola

$ which mvn
/opt/apache-maven-3.1.0/bin/mvn

not quite yum but closer to home ;)

For CentOS/RHEL:

yum install mysql-devel -y

Three ways you can do this - from the form designer, select the form, and where you normally see the list of properties, just above it there should be a little lightning symbol - this shows you all the events of the form. Find the form load event in the list, and you should be able to pick ProgramViwer_Load from the dropdown.

A second way to do it is programmatically - somewhere (constructor maybe) you'd need to add it, something like: ProgramViwer.Load += new EventHandler(ProgramViwer_Load);

A third way using the designer (probably the quickest) - when you create a new form, double click on the middle of it on it in design mode. It'll create a Form load event for you, hook it in, and take you to the event handler code. Then you can just add your two lines and you're good to go!

Here is another way, by rotating element with the scrollbar for 180deg, wrapping it's content into another element, and rotating that wrapper for -180deg. Check the snippet below

div {_x000D_
  display: inline-block;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_

  margin: 15px;_x000D_
}_x000D_
#vertical {_x000D_
  direction: rtl;_x000D_
  overflow-y: scroll;_x000D_
  overflow-x: hidden;_x000D_
  background: gold;_x000D_
}_x000D_
#vertical p {_x000D_
  direction: ltr;_x000D_
  margin-bottom: 0;_x000D_
}_x000D_
#horizontal {_x000D_
  direction: rtl;_x000D_
  transform: rotate(180deg);_x000D_
  overflow-y: hidden;_x000D_
  overflow-x: scroll;_x000D_
  background: tomato;_x000D_
  padding-top: 30px;_x000D_
}_x000D_
#horizontal span {_x000D_
  direction: ltr;_x000D_
  display: inline-block;_x000D_
  transform: rotate(-180deg);_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

You might have to remove a stale/invalid OAuth response.

Credit: node.js google oauth2 sample stopped working invalid_grant

Note: An OAuth response will also become invalid if the password used in the initial authorization has been changed.

If in a bash environment, you can use the following to remove the stale response:

rm /Users/<username>/.credentials/<authorization.json>

Just an important note: the accepted answer above will not work correctly for keyCode >= 144, i.e. period, comma, dash, etc. For those you should use a more general algorithm:

let chrCode = keyCode - 48 * Math.floor(keyCode / 48);
let chr = String.fromCharCode((96 <= keyCode) ? chrCode: keyCode);

If you're curious as to why, this is apparently necessary because of the behavior of the built-in JS function String.fromCharCode(). For values of keyCode <= 96 it seems to map using the function:

chrCode = keyCode - 48 * Math.floor(keyCode / 48)

For values of keyCode > 96 it seems to map using the function:

chrCode = keyCode

If this seems like odd behavior then well..I agree. Sadly enough, it would be very far from the weirdest thing I've seen in the JS core.

document.onkeydown = function(e) {_x000D_
    let keyCode = e.keyCode;_x000D_
    let chrCode = keyCode - 48 * Math.floor(keyCode / 48);_x000D_
    let chr = String.fromCharCode((96 <= keyCode) ? chrCode: keyCode);_x000D_
    console.log(chr);_x000D_
};

<input type="text" placeholder="Focus and Type"/>

If you are using Mongoose,

try {
  const data = await GPSDatas.aggregate([
    {
      $match: { createdAt : { $gt: new Date() }
    },
    {
      $sort: { createdAt: 1 }
    }
  ])
  console.log(data)

} catch(error) {
    console.log(error)
}

String url = "https://www.murait.com/";
if (url.startsWith("https://") || url.startsWith("http://")) {
    Uri uri = Uri.parse(url);
    Intent intent = new Intent(Intent.ACTION_VIEW, uri);
    startActivity(intent);
}else{
    Toast.makeText(mContext, "Invalid Url", Toast.LENGTH_SHORT).show();
}

You have to check that the URL is valid or not. If URL is invalid application may crash so that you have to check URL is valid or not by this method.

A small variation but nothing new infact. It's really missing a feature...

select info->>'name' from rabbits 
where '"carrots"' = ANY (ARRAY(
    select * from json_array_elements(info->'food'))::text[]);

If you want to save the changes on the log messages, use the batch script from the answer above from @patmortech (https://stackoverflow.com/a/468475),
who copied the script from https://stackoverflow.com/a/68850,
and add these lines between if "%bIsEmpty%" == "true" goto ERROR_EMPTY and goto :eofbefore:

set outputFile=%repos%\log-change-history.txt

echo User '%user%' changes log message in rev %rev% on %date% %time%.>>%outputFile%
echo ----- Old message: ----->>%outputFile%
svnlook propget --revprop %repos% svn:log -r %rev% >>%outputFile%
echo.>>%outputFile%
echo ----- New message: ----->>%outputFile%
for /f "tokens=*" %%g in ('find /V ""') do (echo %%g >>%outputFile%)
echo ---------->>%outputFile%
echo.>>%outputFile%

It will create a text file log-change-history.txt in the repo folder on the server and append each log change notification.

In my case, we have time series from different devices but some devices could not send any value during some period. So we should create NA values for every device and time period and after that do fillna.

df = pd.DataFrame([["device1", 1, 'first val of device1'], ["device2", 2, 'first val of device2'], ["device3", 3, 'first val of device3']])
df.pivot(index=1, columns=0, values=2).fillna(method='ffill').unstack().reset_index(name='value')

Result:

        0   1   value
0   device1     1   first val of device1
1   device1     2   first val of device1
2   device1     3   first val of device1
3   device2     1   None
4   device2     2   first val of device2
5   device2     3   first val of device2
6   device3     1   None
7   device3     2   None
8   device3     3   first val of device3

Why not measure it:

class Program
{
    class NameComparer : IComparer<string>
    {
        public int Compare(string x, string y)
        {
            return string.Compare(x, y, true);
        }
    }

    class Person
    {
        public Person(string id, string name)
        {
            Id = id;
            Name = name;
        }
        public string Id { get; set; }
        public string Name { get; set; }
    }

    static void Main()
    {
        List<Person> persons = new List<Person>();
        persons.Add(new Person("P005", "Janson"));
        persons.Add(new Person("P002", "Aravind"));
        persons.Add(new Person("P007", "Kazhal"));

        Sort(persons);
        OrderBy(persons);

        const int COUNT = 1000000;
        Stopwatch watch = Stopwatch.StartNew();
        for (int i = 0; i < COUNT; i++)
        {
            Sort(persons);
        }
        watch.Stop();
        Console.WriteLine("Sort: {0}ms", watch.ElapsedMilliseconds);

        watch = Stopwatch.StartNew();
        for (int i = 0; i < COUNT; i++)
        {
            OrderBy(persons);
        }
        watch.Stop();
        Console.WriteLine("OrderBy: {0}ms", watch.ElapsedMilliseconds);
    }

    static void Sort(List<Person> list)
    {
        list.Sort((p1, p2) => string.Compare(p1.Name, p2.Name, true));
    }

    static void OrderBy(List<Person> list)
    {
        var result = list.OrderBy(n => n.Name, new NameComparer()).ToArray();
    }
}

On my computer when compiled in Release mode this program prints:

Sort: 1162ms
OrderBy: 1269ms

UPDATE:

As suggested by @Stefan here are the results of sorting a big list fewer times:

List<Person> persons = new List<Person>();
for (int i = 0; i < 100000; i++)
{
    persons.Add(new Person("P" + i.ToString(), "Janson" + i.ToString()));
}

Sort(persons);
OrderBy(persons);

const int COUNT = 30;
Stopwatch watch = Stopwatch.StartNew();
for (int i = 0; i < COUNT; i++)
{
    Sort(persons);
}
watch.Stop();
Console.WriteLine("Sort: {0}ms", watch.ElapsedMilliseconds);

watch = Stopwatch.StartNew();
for (int i = 0; i < COUNT; i++)
{
    OrderBy(persons);
}
watch.Stop();
Console.WriteLine("OrderBy: {0}ms", watch.ElapsedMilliseconds);

Prints:

Sort: 8965ms
OrderBy: 8460ms

In this scenario it looks like OrderBy performs better.

UPDATE2:

And using random names:

List<Person> persons = new List<Person>();
for (int i = 0; i < 100000; i++)
{
    persons.Add(new Person("P" + i.ToString(), RandomString(5, true)));
}

Where:

private static Random randomSeed = new Random();
public static string RandomString(int size, bool lowerCase)
{
    var sb = new StringBuilder(size);
    int start = (lowerCase) ? 97 : 65;
    for (int i = 0; i < size; i++)
    {
        sb.Append((char)(26 * randomSeed.NextDouble() + start));
    }
    return sb.ToString();
}

Yields:

Sort: 8968ms
OrderBy: 8728ms

Still OrderBy is faster

You can clear out their values by just setting value to an empty string:

var1.value = '';
var2.value = '';

There seems also to be a relation to the environment:

I had that "invalid argument supplied foreach()" error only in the dev environment, but not in prod (I am working on the server, not localhost).

Despite the error a var_dump indicated that the array was well there (in both cases app and dev).

The if (is_array($array)) around the foreach ($array as $subarray) solved the problem.

Sorry, that I cannot explain the cause, but as it took me a while to figure a solution I thought of better sharing this as an observation.

I suspect that this occurs after an attempt to undeploy your app. Do you ever kill off that thread that you've initialised during the init() process ? I would do this in the corresponding destroy() method.

Use,..

Color.parseColor("#bdbdbd");

like,

mTextView.setTextColor(Color.parseColor("#bdbdbd"));

Or if you have defined color code in resource's color.xml file than

(From API >= 23)

mTextView.setTextColor(ContextCompat.getColor(context, R.color.<name_of_color>));

(For API < 23)

mTextView.setTextColor(getResources().getColor(R.color.<name_of_color>));

For Postgresql you can use PERFORM. PERFORM is only valid within PL/PgSQL procedure language.

DO $$ BEGIN
    PERFORM "saveUser"(3, 'asd','asd','asd','asd','asd');
END $$;

The suggestion from the postgres team:

HINT: If you want to discard the results of a SELECT, use PERFORM instead.

I haven't tried it but if you put a div in your table cell set so that it will have scrollbars if needed, then you could insert in there, with a fixed height on the div and it should keep your table row to a fixed height.

For recursive components that are not registered globally, it is essential to use not 'any name', but the EXACTLY same name as your component.

Let me give an example:

<template>
    <li>{{tag.name}}
        <ul v-if="tag.sub_tags && tag.sub_tags.length">
            <app-tag v-for="subTag in tag.sub_tags" v-bind:tag="subTag" v-bind:key="subTag.name"></app-tag>
        </ul>
    </li>
</template>

<script>
    export default {
        name: "app-tag",  // using EXACTLY this name is essential

        components: {

        },

        props: ['tag'],
    }

You can use css

.ads{pointer-events:none}

or Using javascript prevent event

$("selector").click(function(event){
   event.preventDefault();
});

Based on CMS answer. I don't get the value directly, instead I take the key at its index and use this to get the value:

Object.keyAt = function(obj, index) {
    var i = 0;
    for (var key in obj) {
        if ((index || 0) === i++) return key;
    }
};


var obj = {
    foo: '1st',
    bar: '2nd',
    baz: '3rd'
};

var key = Object.keyAt(obj, 1);
var val = obj[key];

console.log(key); // => 'bar'
console.log(val); // => '2nd'

As far as I understood the problem, we can find palindromes around a center index and span our search both ways, to the right and left of the center. Given that and knowing there's no palindrome on the corners of the input, we can set the boundaries to 1 and length-1. While paying attention to the minimum and maximum boundaries of the String, we verify if the characters at the positions of the symmetrical indexes (right and left) are the same for each central position till we reach our max upper bound center.

The outer loop is O(n) (max n-2 iterations), and the inner while loop is O(n) (max around (n / 2) - 1 iterations)

Here's my Java implementation using the example provided by other users.

class LongestPalindrome {

    /**
     * @param input is a String input
     * @return The longest palindrome found in the given input.
     */
    public static String getLongestPalindrome(final String input) {
        int rightIndex = 0, leftIndex = 0;
        String currentPalindrome = "", longestPalindrome = "";
        for (int centerIndex = 1; centerIndex < input.length() - 1; centerIndex++) {
            leftIndex = centerIndex - 1;  rightIndex = centerIndex + 1;
            while (leftIndex >= 0 && rightIndex < input.length()) {
                if (input.charAt(leftIndex) != input.charAt(rightIndex)) {
                    break;
                }
                currentPalindrome = input.substring(leftIndex, rightIndex + 1);
                longestPalindrome = currentPalindrome.length() > longestPalindrome.length() ? currentPalindrome : longestPalindrome;
                leftIndex--;  rightIndex++;
            }
        }
        return longestPalindrome;
    }

    public static void main(String ... args) {
        String str = "HYTBCABADEFGHABCDEDCBAGHTFYW12345678987654321ZWETYGDE";

        System.out.println("String: " + str);
        System.out.println("Longest Palindrome: " + longestPali);

HTML

<div id="container">

        some text
    </div>
</div>

CSS

#container {
    width: 50%; /* desired width */

    padding-bottom: 100%;
}

Following line in above code is not working

DB_PASSWORD=$(eval echo ${DB_PASSWORD} | base64 --decode)

Correct line is:

DB_PASSWORD=`echo $PASSWORD|base64 -d`

And save the password in other file as PASSWORD.

Try nslookup google.com to determine if there's a DNS issue. 192.168.1.254 is your local network address and it looks like your system is using it as a DNS server. Is this your gateway/modem router as well? What happens when you try ping google.com. Can you browse to it on a Internet web browser?

The solutions above are completely changed and deprecated. If you want to use CSS modules (assuming you imported css-loaders) and I have been trying to find an answer for this for such a long time and finally did. The default webpack loader is quite different in the new version.

In your webpack, you need to find a part starting with cssRegex and replace it with this;

{
  test: cssRegex,
  exclude: cssModuleRegex,
  use: getStyleLoaders({
      importLoaders: 1,
      modules: true,
      localIdentName: '[name]__[local]__[hash:base64:5]'
  }),
}

The easiest solution is to use

Visual Studio 2012 Color Theme

Use:

ini_set('display_errors','off');

It is working fine in WordPress' config.php.

The reason is that the Scanner class is designed for reading in whitespace-separated tokens. It's a convenience class that wraps an underlying input stream. Before scanner all you could do was read in single bytes, and that's a big pain if you want to read words or lines. With Scanner you pass in System.in, and it does a number of read() operations to tokenize the input for you. Reading a single character is a more basic operation. Source

You can use (char) System.in.read();.

The trouble looks like the image isn't square and the browser adjusts as such. After rotation ensure the dimensions are retained by changing the image margin.

.imagetest img {
  transform: rotate(270deg);
  ...
  margin: 10px 0px;
}

The amount will depend on the difference in height x width of the image. You may also need to add display:inline-block; or display:block to get it to recognize the margin parameter.

Why not something like this?

It uses a combination of lists, iteration, and interpolation.

@mixin placeholder ($rules) {

  @each $rule in $rules {
    ::-webkit-input-placeholder,
    :-moz-placeholder,
    ::-moz-placeholder,
    :-ms-input-placeholder {
      #{nth($rule, 1)}: #{nth($rule, 2)};
    }  
  }
}

$rules: (('border', '1px solid red'),
         ('color', 'green'));

@include placeholder( $rules );

None of the above answers worked for me. I kept getting this error:

Copy-Item : Access is denied
+ CategoryInfo          : PermissionDenied: (\\192.168.1.100\Shared\test.txt:String) [Copy-Item], UnauthorizedAccessException>   
+ FullyQualifiedErrorId : ItemExistsUnauthorizedAccessError,Microsoft.PowerShell.Commands.CopyItemCommand

So this did it for me:

netsh advfirewall firewall set rule group="File and Printer Sharing" new enable=yes

Then from my host my machine in the Run box I just did this:

For someone not using the signing configs and trying to test out the Cordova Release command by typing all the parameters at command line, you may need to enclose your passwords with single quotes if you have special characters in your password

cordova run android --release -- --keystore=../my-release-key.keystore --storePassword='password' --alias=alias_name --password='password'

If your file idea/workspace.xml is added to .gitignore (or its parent folder) just add it manually to git version control. Also you can add it using TortoiseGit. After the next push you will see, that your problem is solved.

Are you targeting the android.R or the one in your own project?

Are you sure your own R.java file is generated? Mistakes in your xml views could cause the R.java not to be generated. Go through your view files and make sure all the xml is right!

In case you are using Visual Studio 2012, for this to work and in order to make reference to Microsoft Office Core, you have to make the reference through Visual Studio by clicking on the top menu's Project, Add Reference, Extensions button and checking office which is now (14.0).

A different take on this question, which might help someone:

I came here because I was debugging in Visual Studio on Windows, and I got confused about all this / vs \\ discussion (it really should not matter in most cases).

For me, the problem was: the "current directory" was not set to what I wanted in Visual Studio. It defaults to the directory of the executable (depending on how you set up your project).

Change it via: Right-click the solution -> Properties -> Working Directory

I only mention it because the question seems Windows-centric, which generally also means VisualStudio-centric, which tells me this hint might be relevant (:

In SQL Developer: Everything was working fine and I had all the permissions to login and there was no password change and I could click the table and see the data tab.

But when I run query (simple select statement) it was showing "ORA-01031: insufficient privileges" message.

The solution is simply disconnect the connection and reconnect. Note: only doing Reconnect did not work for me. SQL Developer Disconnect Snapshot

You can prefer quick-json parser to meet your requirement...

quick-json parser is very straight forward, flexible, very fast and customizable. Try this out

[quick-json parser] (https://code.google.com/p/quick-json/) - quick-json features -

• Compliant with JSON specification (RFC4627)

• High-Performance JSON parser

• Supports Flexible/Configurable parsing approach

• Configurable validation of key/value pairs of any JSON Heirarchy

• Easy to use # Very Less foot print

• Raises developer friendly and easy to trace exceptions

• Pluggable Custom Validation support - Keys/Values can be validated by configuring custom validators as and when encountered

• Validating and Non-Validating parser support

• Support for two types of configuration (JSON/XML) for using quick-json validating parser

• Require JDK 1.5 # No dependency on external libraries

• Support for Json Generation through object serialization

• Support for collection type selection during parsing process

For e.g.

JsonParserFactory factory=JsonParserFactory.getInstance();
JSONParser parser=factory.newJsonParser();
Map jsonMap=parser.parseJson(jsonString);

Method overriding is when a child class redefines the same method as a parent class, with the same parameters. For example, the standard Java class java.util.LinkedHashSet extends java.util.HashSet. The method add() is overridden in LinkedHashSet. If you have a variable that is of type HashSet, and you call its add() method, it will call the appropriate implementation of add(), based on whether it is a HashSet or a LinkedHashSet. This is called polymorphism.

Method overloading is defining several methods in the same class, that accept different numbers and types of parameters. In this case, the actual method called is decided at compile-time, based on the number and types of arguments. For instance, the method System.out.println() is overloaded, so that you can pass ints as well as Strings, and it will call a different version of the method.

Someone with more reputation can copy this into the main answer:

• Change Tracking. Allows you to get info on what changes happened to which rows since a specific version.
• Change Data Capture. Allows all changes to be captured and queried. (Enterprise)

Whenever you use

export someobject

and someobject is

{
 "prop1":"Property1",
 "prop2":"Property2",
}

the above you can import anywhere using import or module.js and there you can use someobject. This is not a restriction that someobject will be an object only it can be a function too, a class or an object.

When you say

new Object()

like you said

new Vue({
  el: '#app',
  data: []
)}

Here you are initiating an object of class Vue.

I hope my answer explains your query in general and more explicitly.

I wouldnt use this attribute as most browsers ignore it as CMS points out.

By all means use client side validation but only in conjunction with server side. Any client side validation can be got round.

Slightly off topic but some people check the content type to validate the uploaded file. You need to be careful about this as an attacker can easily change it and upload a php file for example. See the example at: http://www.scanit.be/uploads/php-file-upload.pdf

After hours of searching and testing finally got it just after posting the question!

You can use the "AnchorPane.topAnchor, AnchorPane.bottomAnchor, AnchorPane.leftAnchor, AnchorPane.rightAnchor" fxml commands with the value "0.0" to fit/stretch/align the child elements inside a AnchorPane. So, these commands tell to child element to follow its parent while resizing.

My updated code Main.fxml

<?xml version="1.0" encoding="UTF-8"?>

<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>

<AnchorPane fx:id="anchorPane" xmlns:fx="http://javafx.com/fxml" fx:controller="app.MainController">
    <!--<StackPane fx:id="stackPane" ></StackPane>--> <!-- replace with the following -->
    <StackPane fx:id="stackPane" AnchorPane.topAnchor="0.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" ></StackPane>
</AnchorPane>

Here is the result:

For api documentation: http://docs.oracle.com/javafx/2/api/javafx/scene/layout/AnchorPane.html

You need to call the AddAddress function once for each E-Mail address you want to send to. There are only two arguments for this function: recipient_email_address and recipient_name. The recipient name is optional and will not be used if not present.

$mailer->AddAddress('[email protected]', 'First Name');
$mailer->AddAddress('[email protected]', 'Second Name');
$mailer->AddAddress('[email protected]', 'Third Name');

You could use an array to store the recipients and then use a for loop. I hope it helps.

Unset will destroy a particular session variable whereas session_destroy() will destroy all the session data for that user.

It really depends on your application as to which one you should use. Just keep the above in mind.

unset($_SESSION['name']); // will delete just the name data

session_destroy(); // will delete ALL data associated with that user.

No need to create a GD resource, as someone else suggested.

$input = 'http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com';
$output = 'google.com.jpg';
file_put_contents($output, file_get_contents($input));

Note: this solution only works if you're setup to allow fopen access to URLs. If the solution above doesn't work, you'll have to use cURL.

There is a better solution now: Vertical align anything with just 3 lines of CSS

I got this problem after adding a new platform to my project. In my case .csproj file was under Perforce source control and was read-only. I checked it out but VS didn't catch the change until I restarted it.

Check out this link it has a example code to encrypt/decrypt data using AES256CBC using EVP API.

https://github.com/saju/misc/blob/master/misc/openssl_aes.c

Also you can check the use of AES256 CBC in a detailed open source project developed by me at https://github.com/llubu/mpro

The code is detailed enough with comments and if you still need much explanation about the API itself i suggest check out this book Network Security with OpenSSL by Viega/Messier/Chandra (google it you will easily find a pdf of this..) read chapter 6 which is specific to symmetric ciphers using EVP API.. This helped me a lot actually understanding the reasons behind using various functions and structures of EVP.

and if you want to dive deep into the Openssl crypto library, i suggest download the code from the openssl website (the version installed on your machine) and then look in the implementation of EVP and aeh api implementation.

One more suggestion from the code you posted above i see you are using the api from aes.h instead use EVP. Check out the reason for doing this here OpenSSL using EVP vs. algorithm API for symmetric crypto nicely explained by Daniel in one of the question asked by me..

Wow...there is a lot of low-level security code in this thread -- most of which did not work for me, either -- although I learned a lot in the process. One thing that I learned is that most of this code is not geared to applications seeking per user access rights -- it is for Administrators wanting to alter rights programmatically, which -- as has been pointed out -- is not a good thing. As a developer, I cannot use the "easy way out" -- by running as Administrator -- which -- I am not one on the machine that runs the code, nor are my users -- so, as clever as these solutions are -- they are not for my situation, and probably not for most rank and file developers, either.

Like most posters of this type of question -- I initially felt it was "hackey", too -- I have since decided that it is perfectly alright to try it and let the possible exception tell you exactly what the user's rights are -- because the information I got did not tell me what the rights actually were. The code below -- did.

  Private Function CheckUserAccessLevel(folder As String) As Boolean
Try
  Dim newDir As String = String.Format("{0}{1}{2}",
                                       folder,
                                       If(folder.EndsWith("\"),
                                          "",
                                          "\"),
                                       "LookWhatICanDo")
  Dim lookWhatICanDo = Directory.CreateDirectory(newDir)

  Directory.Delete(newDir)
  Return True

Catch ex As Exception
  Return False
End Try

End Function

Check out if you are install MySQL server, I've faced this issue and resolve it by this steps:

1- Windows > MySQL installer - community 2- Then click on Add > then select MySQL Server and next. .....

I hope that resolve your issue

As pointed above, BFS can only be used to find shortest path in a graph if:

1. There are no loops

2. All edges have same weight or no weight.

To find the shortest path, all you have to do is start from the source and perform a breadth first search and stop when you find your destination Node. The only additional thing you need to do is have an array previous[n] which will store the previous node for every node visited. The previous of source can be null.

To print the path, simple loop through the previous[] array from source till you reach destination and print the nodes. DFS can also be used to find the shortest path in a graph under similar conditions.

However, if the graph is more complex, containing weighted edges and loops, then we need a more sophisticated version of BFS, i.e. Dijkstra's algorithm.

If above solutions doesn't work, try to change the default por from 3306, to another one (i.e. 3307)

Here is the annotation based example:

@SpringBootApplication
@ImportResource({"classpath*:spring-config.xml"})
public class MainApplication {

    public static void main(String[] args) {
        SpringApplication.run(MainApplication.class, args);
    }
}

Just escape the "\" by using + "\\Tasks" or use a verbatim string like @"\Tasks"

TreeSize professional has what you want. but it focus on the sizes of folders and files.

Just create a data.frame with 0 length variables

eg

nodata <- data.frame(x= numeric(0), y= integer(0), z = character(0))
str(nodata)

## 'data.frame':    0 obs. of  3 variables:
##  $ x: num 
##  $ y: int 
##  $ z: Factor w/ 0 levels: 

or to create a data.frame with 5 columns named a,b,c,d,e

nodata <- as.data.frame(setNames(replicate(5,numeric(0), simplify = F), letters[1:5]))

You need to do the subselect based on a column name, not *.

For example, if you had an id field common to both tables, you could do:

SELECT * FROM Table1 WHERE id NOT IN (SELECT id FROM Table2)

Refer to the MySQL subquery syntax for more examples.

PHP

Add this in your HTML or PHP code:

<?php if (!isset($_SERVER['HTTP_USER_AGENT']) || stripos($_SERVER['HTTP_USER_AGENT'], 'Speed Insights') === false): ?>
  <script>
    (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
    (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
    m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
    })(window,document,'script','https://www.google-analytics.com/analytics.js','ga');

    ga('create', 'UA-PUT YOUR GOOGLE ANALYTICS ID HERE', 'auto');
    ga('send', 'pageview');
  </script>
<?php endif; ?>

JavaScript

This works fine with JavaScript:

  <script>
  if(navigator.userAgent.indexOf("Speed Insights") == -1) {
    (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
    (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
    m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
    })(window,document,'script','https://www.google-analytics.com/analytics.js','ga');

    ga('create', 'UA-<PUT YOUR GOOGLE ANALYTICS ID HERE>', 'auto');
    ga('send', 'pageview');
  }
  </script>

NiloVelez already said: Obviously, it won't make any real improvement, but if your only concern is getting a 100/100 score this will do it.

You can use a table

<table class="formcontrols" >   
    <tr>
        <td>
            <label for="firstName">FirstName:</label>
        </td>
        <td  style="padding-left:10px;">
            <input id="firstName" name="firstName" value="John">
        </td>
    </tr>
    <tr>
        <td>
            <label for="Test">Last name:</label>
        </td>
        <td  style="padding-left:10px;">
            <input id="lastName" name="lastName" value="Travolta">
        </td>
    </tr>
</table>

The result would be: ImageResult

JavaScript code:

• on mousedown event: set selectedIndex property value to -1

The only drawback is that when the user clicks on the dropdown list, the currently selected item does not appear selected

Use the DataFrame returned by:

yourDF.orderBy(account)

There is no explicit way to use partitionBy on a DataFrame, only on a PairRDD, but when you sort a DataFrame, it will use that in it's LogicalPlan and that will help when you need to make calculations on each Account.

I just stumbled upon the same exact issue, with a dataframe that I want to partition by account. I assume that when you say "want to have the data partitioned so that all of the transactions for an account are in the same Spark partition", you want it for scale and performance, but your code doesn't depend on it (like using mapPartitions() etc), right?

This error may be actually being show because mysql is already started. Try to see the current status by:

mysql.server status

Why cant you use the finally block?

Like

try {

} catch (Exception e) {

  // THIS WILL EXECUTE IF THERE IS AN EXCEPTION IS THROWN IN THE TRY BLOCK

} finally { 

 // THIS WILL EXECUTE IRRESPECTIVE OF WHETHER AN EXCEPTION IS THROWN WITHIN THE TRY CATCH OR NOT

}

EDIT after question amended:

You can do:

int? returnFromFunction2 = null;
    try {
        returnFromFunction2 = function2();
        return returnFromFunction2.value;
        } catch (Exception e) {

          // THIS WILL EXECUTE IF THERE IS AN EXCEPTION IS THROWN IN THE TRY BLOCK

        } finally { 

        if (returnFromFunction2.HasValue) { // do something with value }

         // THIS WILL EXECUTE IRRESPECTIVE OF WHETHER AN EXCEPTION IS THROWN WITHIN THE TRY CATCH OR NOT

        }

In my case this was happening with a Laravel queue worker. The system logs did not mention any killing so I looked further and it turned out that the worker was basically killing itself because of a job that exceeded the memory limit (which is set to 128M by default).

Running the queue worker with --timeout=600 and --memory=1024 fixed the problem for me.

You can use any one these [starting from the fastest]

$("#moo") > $("#foo #moo") > $("div#foo span#moo") > $("#foo span") > $("#foo > #moo")

Take a look

Liviu's answer was extremely helpful for me. Hope this is not bad form but i made a fiddle that may help someone else out in the future.

Two important pieces that are needed are:

    $scope.entities = [{
    "title": "foo",
    "id": 1
}, {
    "title": "bar",
    "id": 2
}, {
    "title": "baz",
    "id": 3
}];
$scope.selected = [];

One workaround to solve this issue is try to read the object back from hibernate cache/db before you make any updates and then persist.

Example:

            OrderHeader oh = orderHeaderDAO.get(orderHeaderId);
            oh.setShipFrom(facilityForOrder);
            orderHeaderDAO.persist(oh);

Note: Keep in mind that this does not fix the root cause but solves the issue.

For MySQL, you can do it like this:

CREATE TABLE New_Users   SELECT * FROM Old_Users group by ID;

Sometimes it is useful to temporarily change Git's case sensitivity.

Method #1 - Change case sensitivity for a single command:

git -c core.ignorecase=true checkout mybranch to turn off case-sensitivity for a single checkout command. Or more generally: git -c core.ignorecase= <<true or false>> <<command>>. (Credit to VonC for suggesting this in the comments.)

Method #2 - Change case sensitivity for multiple commands:

To change the setting for longer (e.g. if multiple commands need to be run before changing it back):

1. git config core.ignorecase (this returns the current setting, e.g. false).
2. git config core.ignorecase <<true or false>> - set the desired new setting.
3. ...Run multiple other commands...
4. git config core.ignorecase <<false or true>> - set config value back to its previous setting.

8 Defensive Programming

8.2 Assertions

An assertion is code that’s used during development—usually a routine or macro—that allows a program to check itself as it runs. When a assertion is true, that means everything is operating as expected. When it’s false, that means it has detected an unexpected error in the code. For example, if the system assumes that a customer-information file will never have more than 50,000 records, the program might contain an assertion that the number of records is less than or equal to 50,000. As long as the number of records is less than or equal to 50,000, the assertion will be silent. If it encounters more than 50,000 records, however, it will loudly “assert” that there is a error in the program.

Assertions are especially useful in large, complicated programs and in high-reliability programs. They enable programmers to more quickly flush out mismatched interface assumptions, errors that creep in when the code is modified, and so on.

An assertion usually takes two arguments: a boolean expression that describes the assumption that’s supposed to be true and a message to display if it isn’t.

(…)

Normally, you don’t want users to see assertion messages in production code; assertions are primarily for use during development and maintenance. Assertions are normally compiled into the code at development time and compiled out of the code for production. During development, assertions flush out contradictory assumptions, unexpected conditions, bad values passed to routines, and so on. During production, they are compiled out of the code so that the assertions don’t degrade system performance.

In Java there's sadly no way you can avoid using the parseInt function and just catching the exception. Well you could theoretically write your own parser that checks if it's a number, but then you don't need parseInt at all anymore.

The regex method is problematic because nothing stops somebody from including a number > INTEGER.MAX_VALUE which will pass the regex test but still fail.

Below solution worked for me: Navigate to Project->Clean.. Clean all the projects referenced by Tomcat server Refresh the project you're trying to run on Tomcat

Try to run the server afterwards

for those like me still stuck with SQL Server 2000, SET ROWCOUNT {number}; can be used before the UPDATE query

SET ROWCOUNT 100;
UPDATE Table SET ..;
SET ROWCOUNT 0;

will limit the update to 100 rows

It has been deprecated at least since SQL 2005, but as of SQL 2017 it still works. https://docs.microsoft.com/en-us/sql/t-sql/statements/set-rowcount-transact-sql?view=sql-server-2017

For the sake of documentation. I spent two days working out an ajax problem and this afternoon when I started testing, my PHP ajax handler wasn't getting called....

Extraordinarily frustrating.

The solution to my problem (which might help others) is the priority of the add_action.

add_action ('wp_ajax_(my handler), array('class_name', 'static_function'), 1);

recalling that the default priority = 10

I was getting a return code of zero and none of my code was being called.

...noting that this wasn't a WordPress problem, I probably misspoke on this question. My apologies.

The problem is that you have a date formatted like this:

Thu Jun 18 20:56:02 EDT 2009

But are using a SimpleDateFormat that is:

yyyy-MM-dd

The two formats don't agree. You need to construct a SimpleDateFormat that matches the layout of the string you're trying to parse into a Date. Lining things up to make it easy to see, you want a SimpleDateFormat like this:

EEE MMM dd HH:mm:ss zzz yyyy
Thu Jun 18 20:56:02 EDT 2009

Check the JavaDoc page I linked to and see how the characters are used.

data.sort(function(a,b) 
{
   return a.val - b.val;
});

setDate() has issues with month boundaries that are noted in comments above. A clean workaround is to find the date difference using epoch timestamps rather than the (surprisingly counterintuitive) methods on the Date object. I.e.

function getPreviousMonday(fromDate) {
    var dayMillisecs = 24 * 60 * 60 * 1000;

    // Get Date object truncated to date.
    var d = new Date(new Date(fromDate || Date()).toISOString().slice(0, 10));

    // If today is Sunday (day 0) subtract an extra 7 days.
    var dayDiff = d.getDay() === 0 ? 7 : 0;

    // Get date diff in millisecs to avoid setDate() bugs with month boundaries.
    var mondayMillisecs = d.getTime() - (d.getDay() + dayDiff) * dayMillisecs;

    // Return date as YYYY-MM-DD string.
    return new Date(mondayMillisecs).toISOString().slice(0, 10);
}

Maybe your application is compiled with a different JRE than Tomcat.

Check java -version on your server and then compile your code with the same version. I had the error because my Eclipse standard JRE was 1.6 and Tomcat used 1.5 - this can't work.

I'm resurrecting the dead here, but because a range can be defined as "A:A", using a for each loop ends up with a potential infinite loop. The solution, as far as I know, is to use the Do Until loop.

Do Until Selection.Value = ""
  Rem Do things here...
Loop

Here's one possible method.

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

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

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

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

You can use the following code to add column to Datatable at postion 0:

    DataColumn Col   = datatable.Columns.Add("Column Name", System.Type.GetType("System.Boolean"));
    Col.SetOrdinal(0);// to put the column in position 0;

You can use:

 Handler handler = new Handler()
 handler.postDelayed(new Runnable())

Or you can use:

 handler.removeCallbacksAndMessages(null);

Docs

public final void removeCallbacksAndMessages (Object token)

Added in API level 1 Remove any pending posts of callbacks and sent messages whose obj is token. If token is null, all callbacks and messages will be removed.

Or you could also do like the following:

Handler handler =  new Handler()
Runnable myRunnable = new Runnable() {
public void run() {
    // do something
}
};
handler.postDelayed(myRunnable,zeit_dauer2);

Then:

handler.removeCallbacks(myRunnable);

Docs

public final void removeCallbacks (Runnable r)

Added in API level 1 Remove any pending posts of Runnable r that are in the message queue.

public final void removeCallbacks (Runnable r, Object token)

Edit:

Change this:

@Override
public void onClick(View v) {
    Handler handler =  new Handler();
    Runnable myRunnable = new Runnable() {

To:

@Override
public void onClick(View v) {
    handler = new Handler();
    myRunnable = new Runnable() { /* ... */}

Because you have the below. Declared before onCreate but you re-declared and then initialized it in onClick leading to a NPE.

Handler handler; // declared before onCreate
Runnable myRunnable;

add margin:-1px; which reduces 1px to each side. or if you need only for side you can do margin-left:-1px etc.

For future visitors: In the new HttpClient (Angular 4.3+), the response object is JSON by default, so you don't need to do response.json().data anymore. Just use response directly.

Example (modified from the official documentation):

import { HttpClient } from '@angular/common/http';

@Component(...)
export class YourComponent implements OnInit {

  // Inject HttpClient into your component or service.
  constructor(private http: HttpClient) {}

  ngOnInit(): void {
    this.http.get('https://api.github.com/users')
        .subscribe(response => console.log(response));
  }
}

Don't forget to import it and include the module under imports in your project's app.module.ts:

...
import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [
    BrowserModule,
    // Include it under 'imports' in your application module after BrowserModule.
    HttpClientModule,
    ...
  ],
  ...

I used Slaks answer but that wasn't working as is, since the onbeforeunload returnValue is parsed as a string and then displayed in the confirmations box of the browser. So the value true was displayed, like "true".

Just using return worked. Here is my code

var preventUnloadPrompt;
var messageBeforeUnload = "my message here - Are you sure you want to leave this page?";
//var redirectAfterPrompt = "http://www.google.co.in";
$('a').live('click', function() { preventUnloadPrompt = true; });
$('form').live('submit', function() { preventUnloadPrompt = true; });
$(window).bind("beforeunload", function(e) { 
    var rval;
    if(preventUnloadPrompt) {
        return;
    } else {
        //location.replace(redirectAfterPrompt);
        return messageBeforeUnload;
    }
    return rval;
})

 Encoding.Convert(Encoding.Default, Encoding.UTF8, Encoding.Default.GetBytes(mystring));

Once you instantiate a class (using new), that instantiated thing becomes an object. An object is something that can adhere to encapsulation, polymorphism, abstraction principles of object oriented programming and the real thing a program interacts with to consume the instance members defined in class. Object contains instance members (non-static members).

Thus instance of a class is an object. The word ‘instance’ is used when you are referring to the origin from where it born, it's more clearer if you say ‘instance of a class’ compared to ‘object of a class’ (although the latter can be used to).

Can also read the 'Inner classes' section of this java document on nested classes - https://docs.oracle.com/javase/tutorial/java/javaOO/nested.html

Go into Window > Preferences > Java > Installed JREs > and check your installed JREs. You should have an entry with a JDK there.

https://cduu.wordpress.com/2013/03/08/maven-eclipse-compiler-error-no-compiler-is-provided-in-this-environment/

yes you can do this on windows too, here's the code below, using the conio.h library

#include <iostream> //basic input/output
#include <conio.h>  //provides non standard getch() function
using namespace std;

int main()
{  
  cout << "Password: ";  
  string pass;
  while(true)
  {
             char ch = getch();    

             if(ch=='\r'){  //when a carriage return is found [enter] key
             cout << endl << "Your password is: " << pass <<endl; 
             break;
             }

             pass+=ch;             
             cout << "*";
             }
  getch();
  return 0;
}

The code you have is a white with low opacity.

If something white with a low opacity is above something black, you end up with a lighter shade of gray. Above red? Lighter red, etc. That is how opacity works.

Here is a simple demo.

If you want it to look 'more white', make it less opaque:

background:rgba(255,255,255, 0.9);

Demo

Try this Simple Steps....

NOTE: Please check device location latitude & logitude if you are using simulator means. By defaults its none only.

Step 1: Import CoreLocation framework in .h File

#import <CoreLocation/CoreLocation.h>

Step 2: Add delegate CLLocationManagerDelegate

@interface yourViewController : UIViewController<CLLocationManagerDelegate>
{
    CLLocationManager *locationManager;
    CLLocation *currentLocation;
}

Step 3: Add this code in class file

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self CurrentLocationIdentifier]; // call this method
}

Step 4: Method to detect current location

//------------ Current Location Address-----
-(void)CurrentLocationIdentifier
{
    //---- For getting current gps location
    locationManager = [CLLocationManager new];
    locationManager.delegate = self;
    locationManager.distanceFilter = kCLDistanceFilterNone;
    locationManager.desiredAccuracy = kCLLocationAccuracyBest;
    [locationManager startUpdatingLocation];
    //------
}

Step 5: Get location using this method

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    currentLocation = [locations objectAtIndex:0];
    [locationManager stopUpdatingLocation];
    CLGeocoder *geocoder = [[CLGeocoder alloc] init] ;
    [geocoder reverseGeocodeLocation:currentLocation completionHandler:^(NSArray *placemarks, NSError *error)
     {
         if (!(error))
         {
             CLPlacemark *placemark = [placemarks objectAtIndex:0];
             NSLog(@"\nCurrent Location Detected\n");
             NSLog(@"placemark %@",placemark);
             NSString *locatedAt = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "];
             NSString *Address = [[NSString alloc]initWithString:locatedAt];
             NSString *Area = [[NSString alloc]initWithString:placemark.locality];
             NSString *Country = [[NSString alloc]initWithString:placemark.country];
             NSString *CountryArea = [NSString stringWithFormat:@"%@, %@", Area,Country];
             NSLog(@"%@",CountryArea);
         }
         else
         {
             NSLog(@"Geocode failed with error %@", error);
             NSLog(@"\nCurrent Location Not Detected\n");
             //return;
             CountryArea = NULL;
         }
         /*---- For more results 
         placemark.region);
         placemark.country);
         placemark.locality); 
         placemark.name);
         placemark.ocean);
         placemark.postalCode);
         placemark.subLocality);
         placemark.location);
          ------*/
     }];
}

If you are still seeking for the best solution in 2018, I found the way this works perfectly if you have at least one free pseudo element( ::after or ::before ).

You just have to add class to your row like this: <div class="row vertical-divider ">

And add this to your CSS:

.row.vertical-divider [class*='col-']:not(:last-child)::after {
  background: #e0e0e0;
  width: 1px;
  content: "";
  display:block;
  position: absolute;
  top:0;
  bottom: 0;
  right: 0;
  min-height: 70px;
}

Any row with this class will now have vertical divider between all of the columns it contains...

You can see how this works in this example.

In java.util.timer one can use .cancel() to stop the timer and clear all pending tasks.

Use the "containment" option:

jQuery UI API - Draggable Widget - containment

The documentation says it only accepts the values: 'parent', 'document', 'window', [x1, y1, x2, y2] but I seem to remember it will accept a selector such as '#container' too.

This little example shows how the $rootScope emit a event that will be listen by a children scope in another controller.

(function(){


angular
  .module('ExampleApp',[]);

angular
  .module('ExampleApp')
  .controller('ExampleController1', Controller1);

Controller1.$inject = ['$rootScope'];

function Controller1($rootScope) {
  var vm = this, 
      message = 'Hi my children scope boy';

  vm.sayHi = sayHi;

  function sayHi(){
    $rootScope.$broadcast('greeting', message);
  }

}

angular
  .module('ExampleApp')
  .controller('ExampleController2', Controller2);

Controller2.$inject = ['$scope'];

function Controller2($scope) {
  var vm = this;

  $scope.$on('greeting', listenGreeting)

  function listenGreeting($event, message){
    alert(['Message received',message].join(' : '));
  }

}


})();

The answer of @gayathri bottom explain technically the differences of all those methods in the scope angular concept and their implementations $scope and $rootScope.

Guys Its very interesting to know that many of us face the problem of replication of lookup value while using the Vlookup/Index with Match or Hlookup.... If we have duplicate value in a cell we all know, Vlookup will pick up against the first item would be matching in loopkup array....So here is solution for you all...

e.g.

in Column A we have field called company....

Column A                             Column B            Column C

Company_Name                         Value        
Monster                              25000                              
Naukri                               30000  
WNS                                  80000  
American Express                     40000  
Bank of America                      50000  
Alcatel Lucent                       35000  
Google                               75000  
Microsoft                            60000  
Monster                              35000  
Bank of America                      15000 

Now if you lookup the above dataset, you would see the duplicity is in Company Name at Row No# 10 & 11. So if you put the vlookup, the data will be picking up which comes first..But if you use the below formula, you can make your lookup value Unique and can pick any data easily without having any dispute or facing any problem

Put the formula in C2.........A2&"_"&COUNTIF(A2:$A$2,A2)..........Result will be Monster_1 for first line item and for row no 10 & 11.....Monster_2, Bank of America_2 respectively....Here you go now you have the unique value so now you can pick any data easily now..

if you are using matplotlib version 3.1.1 or above, you can try:

import matplotlib.pyplot as plt
from matplotlib.colors import ListedColormap

x = [1, 3, 4, 6, 7, 9]
y = [0, 0, 5, 8, 8, 8]
classes = ['A', 'B', 'C']
values = [0, 0, 1, 2, 2, 2]
colours = ListedColormap(['r','b','g'])
scatter = plt.scatter(x, y,c=values, cmap=colours)
plt.legend(handles=scatter.legend_elements()[0], labels=classes)

Basically, you get connections in the Sleep state when :

• a PHP script connects to MySQL
• some queries are executed
• then, the PHP script does some stuff that takes time
  • without disconnecting from the DB
• and, finally, the PHP script ends
  • which means it disconnects from the MySQL server

So, you generally end up with many processes in a Sleep state when you have a lot of PHP processes that stay connected, without actually doing anything on the database-side.

A basic idea, so : make sure you don't have PHP processes that run for too long -- or force them to disconnect as soon as they don't need to access the database anymore.

Another thing, that I often see when there is some load on the server :

• There are more and more requests coming to Apache
  • which means many pages to generate
• Each PHP script, in order to generate a page, connects to the DB and does some queries
• These queries take more and more time, as the load on the DB server increases
• Which means more processes keep stacking up

A solution that can help is to reduce the time your queries take -- optimizing the longest ones.

Where you want to log data use

console.log("data")

And to print this log in terminal use command for android

npx react-native log-android

and for iOS

npx react-native log-ios

If PowerShell is available, the Send-MailMessage commandlet is a single one-line command that could easily be called from a batch file to handle email notifications. Below is a sample of the line you would include in your batch file to call the PowerShell script (the %xVariable% is a variable you might want to pass from your batch file to the PowerShell script):

--[BATCH FILE]--

:: ...your code here...
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe  -windowstyle hidden -command C:\MyScripts\EmailScript.ps1 %xVariable%

Below is an example of what you might include in your PowerShell script (you must include the PARAM line as the first non-remark line in your script if you included passing the %xVariable% from your batch file:

--[POWERSHELL SCRIPT]--

Param([String]$xVariable)
# ...your code here...
$smtp = "smtp.[emaildomain].com"
$to = "[Send to email address]"
$from = "[From email address]" 
$subject = "[Subject]" 
$body = "[Text you want to include----the <br> is a line feed: <br> <br>]"    
$body += "[This could be a second line of text]" + "<br> "

$attachment="[file name if you would like to include an attachment]"
send-MailMessage -SmtpServer $smtp -To $to -From $from -Subject $subject -Body $body -BodyAsHtml -Attachment $attachment -Priority high  

As there is no implementation of a variable it can't be abstract ;)

For anyone else who gets caught, ensure setCustomAnimations is called before the call to replace/add when building the transaction.

I currently use this simple synchronous method which requires no extra files in your projects or delegates.

Import:

#import <SystemConfiguration/SCNetworkReachability.h>

Create this method:

+(bool)isNetworkAvailable
{
    SCNetworkReachabilityFlags flags;
    SCNetworkReachabilityRef address;
    address = SCNetworkReachabilityCreateWithName(NULL, "www.apple.com" );
    Boolean success = SCNetworkReachabilityGetFlags(address, &flags);
    CFRelease(address);

    bool canReach = success
                    && !(flags & kSCNetworkReachabilityFlagsConnectionRequired)
                    && (flags & kSCNetworkReachabilityFlagsReachable);

    return canReach;
}

Then, if you've put this in a MyNetworkClass:

if( [MyNetworkClass isNetworkAvailable] )
{
   // do something networky.
}

If you are testing in the simulator, turn your Mac's wifi on and off, as it appears the simulator will ignore the phone setting.

Update:

1. In the end I used a thread/asynchronous callback to avoid blocking the main thread; and regularly re-testing so I could use a cached result - although you should avoid keeping data connections open unnecessarily.

2. As @thunk described, there are better URLs to use, which Apple themselves use. http://cadinc.com/blog/why-your-apple-ios-7-device-wont-connect-to-the-wifi-network

I had to convert a string to a byte array for a serial communication project - I had to handle 8-bit characters, and I was unable to find a method using the framework converters to do so that didn't either add two-byte entries or mis-translate the bytes with the eighth bit set. So I did the following, which works:

string message = "This is a message.";
byte[] bytes = new byte[message.Length];
for (int i = 0; i < message.Length; i++)
    bytes[i] = (byte)message[i];

This simple filtering can be achieved in many ways with Python. The best approach is to use "list comprehensions" as follows:

>>> lst = ['a', 'ab', 'abc', 'bac']
>>> [k for k in lst if 'ab' in k]
['ab', 'abc']

Another way is to use the filter function. In Python 2:

>>> filter(lambda k: 'ab' in k, lst)
['ab', 'abc']

In Python 3, it returns an iterator instead of a list, but you can cast it:

>>> list(filter(lambda k: 'ab' in k, lst))
['ab', 'abc']

Though it's better practice to use a comprehension.

Since it's an array before you cast it, casting it makes no sense.

You may want a recursive cast, which would look something like this:

function arrayCastRecursive($array)
{
    if (is_array($array)) {
        foreach ($array as $key => $value) {
            if (is_array($value)) {
                $array[$key] = arrayCastRecursive($value);
            }
            if ($value instanceof stdClass) {
                $array[$key] = arrayCastRecursive((array)$value);
            }
        }
    }
    if ($array instanceof stdClass) {
        return arrayCastRecursive((array)$array);
    }
    return $array;
}

Usage:

$obj = new stdClass;
$obj->aaa = 'asdf';
$obj->bbb = 'adsf43';
$arr = array('asdf', array($obj, 3));

var_dump($arr);
$arr = arrayCastRecursive($arr);
var_dump($arr);

Result before:

array
    0 => string 'asdf' (length = 4)
  1 => 
    array
        0 =>
        object(stdClass)[1]
          public 'aaa' => string 'asdf' (length = 4)
          public 'bbb' => string 'adsf43' (length = 6)
      1 => int 3

Result after:

array
    0 => string 'asdf' (length = 4)
  1 => 
    array
        0 =>
        array
          'aaa' => string 'asdf' (length = 4)
          'bbb' => string 'adsf43' (length = 6)
      1 => int 3

Note:

Tested and working with complex arrays where a stdClass object can contain other stdClass objects.

That solution will open up a new browser window without the normal features such as address bar and similar.

To implement a modal popup, I suggest you to take a look at jQuery and SimpleModal, which is really slick.

(Here are some simple demos using SimpleModal: http://www.ericmmartin.com/projects/simplemodal-demos/)

You can't sort a std::map this way, because a the entries in the map are sorted by the key. If you want to sort by value, you need to create a new std::map with swapped key and value.

map<long, double> testMap;
map<double, long> testMap2;

// Insert values from testMap to testMap2
// The values in testMap2 are sorted by the double value

Remember that the double keys need to be unique in testMap2 or use std::multimap.

All these work:

#include <iostream>
using namespace std;

//Good, because manual memory management isn't needed and this uses
//less heap memory (or no heap memory) so this is safer if
//used in a low memory situation
void f() { throw string("foo"); }

//Valid, but avoid manual memory management if there's no reason to use it
void g() { throw new string("foo"); }

//Best.  Just a pointer to a string literal, so no allocation is needed,
//saving on cleanup, and removing a chance for an allocation to fail.
void h() { throw "foo"; }

int main() {
  try { f(); } catch (string s) { cout << s << endl; }
  try { g(); } catch (string* s) { cout << *s << endl; delete s; }
  try { h(); } catch (const char* s) { cout << s << endl; }
  return 0;
}

You should prefer h to f to g. Note that in the least preferable option you need to free the memory explicitly.

Use the below logic to calculate the n power of a.

Normally if we want to calculate n power of a. We will multiply 'a' by n number of times.Time complexity of this approach will be O(n) Split the power n by 2, calculate Exponentattion = multiply 'a' till n/2 only. Double the value. Now the Time Complexity is reduced to O(n/2).

public  int calculatePower1(int a, int b) {
    if (b == 0) {
        return 1;
    }

    int val = (b % 2 == 0) ? (b / 2) : (b - 1) / 2;

    int temp = 1;
    for (int i = 1; i <= val; i++) {
        temp *= a;
    }

    if (b % 2 == 0) {
        return temp * temp;
    } else {
        return a * temp * temp;
    }
}

Use Scanner.hasNextInt():

Returns true if the next token in this scanner's input can be interpreted as an int value in the default radix using the nextInt() method. The scanner does not advance past any input.

Here's a snippet to illustrate:

Scanner sc = new Scanner(System.in);
System.out.print("Enter number 1: ");
while (!sc.hasNextInt()) sc.next();
int num1 = sc.nextInt();
int num2;
System.out.print("Enter number 2: ");
do {

System.out.println(num1 + " " + num2);

You don't have to parseInt or worry about NumberFormatException. Note that since the hasNextXXX methods don't advance past any input, you may have to call next() if you want to skip past the "garbage", as shown above.

• How do I keep a scanner from throwing exceptions when the wrong type is entered? (java)

Load data infile query is much better option but some servers like godaddy restrict this option on shared hosting so , only two options left then one is insert record on every iteration or batch insert , but batch insert has its limitaion of characters if your query exceeds this number of characters set in mysql then your query will crash , So I suggest insert data in chunks withs batch insert , this will minimize number of connections established with database.best of luck guys

If you want to access redis from the host (127.0.0.1), you have to use the ports command.

redis:
  build:
    context: .
    dockerfile: Dockerfile-redis
    ports:
    - "6379:6379"

For Angular v4 and Above, simply use:

ng g c componentName -m ModuleName

I'm not sure how you could just check if something isn't undefined and at the same time get an error that it is undefined. What browser are you using?

You could check in the following way (extra = and making length a truthy evaluation)

if (typeof(sub.from) !== 'undefined' && sub.from.length) {

[update]

I see that you reset sub and thereby reset sub.from but fail to re check if sub.from exist:

for (var i = 0; i < sub.from.length; i++) {//<== assuming sub.from.exist
            mainid = sub.from[i]['id'];
            var sub = afcHelper_Submissions[mainid]; // <== re setting sub

My guess is that the error is not on the if statement but on the for(i... statement. In Firebug you can break automatically on an error and I guess it'll break on that line (not on the if statement).

Update

the library already have Java/Kotlin support, see github.

To simplify I did a class to be used simply, I added it on Encryption library to use it you just do as follow:

Add the gradle library:

compile 'se.simbio.encryption:library:2.0.0'

and use it:

Encryption encryption = Encryption.getDefault("Key", "Salt", new byte[16]);
String encrypted = encryption.encryptOrNull("top secret string");
String decrypted = encryption.decryptOrNull(encrypted);

if you not want add the Encryption library you can just copy the following class to your project. If you are in an android project you need to import android Base64 in this class, if you are in a pure java project you need to add this class manually you can get it here

Alternatively you could use a loop, keep the row number (counter should be the row number) and stop the loop when you find the first "ProjTemp".
Then it should look something like this:

Sub find()
    Dim i As Integer
    Dim firstTime As Integer
    Dim bNotFound As Boolean

    i = 1
    bNotFound = True

      Do While bNotFound
        If Cells(i, 2).Value = "ProjTemp" Then
            firstTime = i
            bNotFound = false
        End If
        i = i + 1
    Loop
End Sub

The field must be declared public for proper visibility from the ASPX markup. In any case, you could declare a property:

private string clients;
public string Clients { get { return clients; } }

UPDATE: It can also be declared as protected, as stated in the comments below.

Then, to call it on the ASPX side:

<%=Clients%>

Note that this won't work if you place it on a server tag attribute. For example:

<asp:Label runat="server" Text="<%=Clients%>" />

This isn't valid. This is:

<div><%=Clients%></div>

Try using

$(window).unload(function(){
  localStorage.clear();
});

Hope this works for you

malloc() and calloc() are functions from the C standard library that allow dynamic memory allocation, meaning that they both allow memory allocation during runtime.

Their prototypes are as follows:

void *malloc( size_t n);
void *calloc( size_t n, size_t t)

There are mainly two differences between the two:

• Behavior: malloc() allocates a memory block, without initializing it, and reading the contents from this block will result in garbage values. calloc(), on the other hand, allocates a memory block and initializes it to zeros, and obviously reading the content of this block will result in zeros.

• Syntax: malloc() takes 1 argument (the size to be allocated), and calloc() takes two arguments (number of blocks to be allocated and size of each block).

The return value from both is a pointer to the allocated block of memory, if successful. Otherwise, NULL will be returned indicating the memory allocation failure.

Example:

int *arr;

// allocate memory for 10 integers with garbage values
arr = (int *)malloc(10 * sizeof(int)); 

// allocate memory for 10 integers and sets all of them to 0
arr = (int *)calloc(10, sizeof(int));

The same functionality as calloc() can be achieved using malloc() and memset():

// allocate memory for 10 integers with garbage values   
arr= (int *)malloc(10 * sizeof(int));
// set all of them to 0
memset(arr, 0, 10 * sizeof(int)); 

Note that malloc() is preferably used over calloc() since it's faster. If zero-initializing the values is wanted, use calloc() instead.

Try this -

EditText myEditText =  (EditText) findViewById(R.id.vnosEmaila);

String text = myEditText.getText().toString();

From the official Python documentation:

String literals can span multiple lines. One way is using triple-quotes: """...""" or '''...'''. End of lines are automatically included in the string, but it’s possible to prevent this by adding a \ at the end of the line. The following example:

print("""\
Usage: thingy [OPTIONS]
     -h                        Display this usage message
     -H hostname               Hostname to connect to
""")

produces the following output (note that the initial newline is not included):

Using default maven (which comes with IntelliJ) also could create this problem. So configure the maven which you have installed.

This can be done from: File -> Settings -> Build, Execution, Deployment -> Maven

Update following settings according to your maven installation:

1. Maven home directory =
2. User settings file =
3. Local repository =

If you find you need to stick with finditer(), you can simply use a counter while you iterate through the iterator.

Example:

>>> from re import *
>>> pattern = compile(r'.ython')
>>> string = 'i like python jython and dython (whatever that is)'
>>> iterator = finditer(pattern, string)
>>> count = 0
>>> for match in iterator:
        count +=1
>>> count
3

If you need the features of finditer() (not matching to overlapping instances), use this method.

For Ubuntu/Debian OS,

apt-get install -y pkg-config

For Redhat/Yum OS,

yum install -y pkgconfig

For Archlinux OS,

pacman -S pkgconf

You can change the value of a bool all you want. As for an if:

if randombool == True:

works, but you can also use:

if randombool:

If you want to test whether something is false you can use:

if randombool == False

but you can also use:

if not randombool:

Use getTime() to get the numeric value of the date, and then compare using the returned values.

I have modified paercebal's method to meet my needs:

typedef std::string String;    

bool isInt(const String& s, int base){
   if(s.empty() || std::isspace(s[0])) return false ;
   char * p ;
   strtol(s.c_str(), &p, base) ;
   return (*p == 0) ;
}


bool isPositiveInt(const String& s, int base){
   if(s.empty() || std::isspace(s[0]) || s[0]=='-') return false ;
   char * p ;
   strtol(s.c_str(), &p, base) ;
   return (*p == 0) ;
}


bool isNegativeInt(const String& s, int base){
   if(s.empty() || std::isspace(s[0]) || s[0]!='-') return false ;
   char * p ;
   strtol(s.c_str(), &p, base) ;
   return (*p == 0) ;
}

Note:

1. You can check for various bases (binary, oct, hex and others)
2. Make sure you don't pass 1, negative value or value >36 as base.
3. If you pass 0 as the base, it will auto detect the base i.e for a string starting with 0x will be treated as hex and string starting with 0 will be treated as oct. The characters are case-insensitive.
4. Any white space in string will make it return false.

this will do your job

  textarea{
        resize:none;
    }

According to Html5 specs you should use -- element.options[e.selectedIndex].text

e.g. if you have select box like below :

<select id="selectbox1">
    <option value="1">First</option>
    <option value="2" selected="selected">Second</option>
    <option value="3">Third</option>
</select>
<br/>
<button onClick="GetItemValue('selectbox1');">Get Item</button>

you can get value using following script :

<script>
 function GetItemValue(q) {
   var e = document.getElementById(q);
   var selValue = e.options[e.selectedIndex].text ;
   alert("Selected Value: "+selValue);
 }
</script>

Tried and tested.

from @Przemek 's answer,

function listenClickOnly(element, callback, threshold=10) {
  let drag = 0;
  element.addEventListener('mousedown', () => drag = 0);
  element.addEventListener('mousemove', () => drag++);
  element.addEventListener('mouseup', e => {
    if (drag<threshold) callback(e);
  });
}

listenClickOnly(
  document,
  () => console.log('click'),
  10
);

You need to use:

await client.PostAsync(uri, content);

Something like that:

var comment = "hello world";
var questionId = 1;

var formContent = new FormUrlEncodedContent(new[]
{
    new KeyValuePair<string, string>("comment", comment), 
    new KeyValuePair<string, string>("questionId", questionId) 
});

var myHttpClient = new HttpClient();
var response = await myHttpClient.PostAsync(uri.ToString(), formContent);

And if you need to get the response after post, you should use:

var stringContent = await response.Content.ReadAsStringAsync();

Hope it helps ;)

The macro NDEBUG controls whether assert() statements are active or not.

In my view, that is separate from any other debugging - so I use something other than NDEBUG to control debugging information in the program. What I use varies, depending on the framework I'm working with; different systems have different enabling macros, and I use whatever is appropriate.

If there is no framework, I'd use a name without a leading underscore; those tend to be reserved to 'the implementation' and I try to avoid problems with name collisions - doubly so when the name is a macro.

I'm pretty sure GSON serializes/deserializes Maps and multiple-nested Maps (i.e. Map<String, Map<String, Object>>) just fine by default. The example provided I believe is nothing more than just a starting point if you need to do something more complex.

Check out the MapTypeAdapterFactory class in the GSON source: http://code.google.com/p/google-gson/source/browse/trunk/gson/src/main/java/com/google/gson/internal/bind/MapTypeAdapterFactory.java

So long as the types of the keys and values can be serialized into JSON strings (and you can create your own serializers/deserializers for these custom objects) you shouldn't have any issues.

Simple ruby script based on this answer: registry_cleaner.

You can run it on local machine:

./registry_cleaner.rb --host=https://registry.exmpl.com --repository=name --tags_count=4

And then on the registry machine remove blobs with /bin/registry garbage-collect /etc/docker/registry/config.yml.

Another solution I found (especially useful if you want to set a global behaviour) is to use the $.ajaxsetup() method together with the statusCode property. Like others pointed out, don't use a redirect statuscode (3xx), instead use a 4xx statuscode and handle the redirect client-side.

$.ajaxSetup({ 
  statusCode : {
    400 : function () {
      window.location = "/";
    }
  }
});

Replace 400 with the statuscode you want to handle. Like already mentioned 401 Unauthorized could be a good idea. I use the 400 since it's very unspecific and I can use the 401 for more specific cases (like wrong login credentials). So instead of redirecting directly your backend should return a 4xx error-code when the session timed out and you you handle the redirect client-side. Works perfect for me even with frameworks like backbone.js
