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

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

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.

I'm not sure what you're trying to do, but here's something to consider: c(); won't do anything. c is an instance of the class checkbox and not a method to be called. So consider this:

public class FirstWindow extends JFrame {      public FirstWindow() {         checkbox c = new checkbox();         c.yourMethod(yourParameters); // call the method you made in checkbox     } }  public class checkbox extends JFrame {      public checkbox(yourParameters) {          // this is the constructor method used to initialize instance variables     }      public void yourMethod() // doesn't have to be void     {         // put your code here     } } 

Not the exception handling mechanism, But you can use the signal() mechanism that is provided by the C.

> man signal

     11    SIGSEGV      create core image    segmentation violation

Writing to a NULL pointer is probably going to cause a SIGSEGV signal

Try to set the element's value using the executeScript method of JavascriptExecutor:

WebDriver driver = new FirefoxDriver();
JavascriptExecutor jse = (JavascriptExecutor)driver;
jse.executeScript("document.getElementById('elementID').setAttribute('value', 'new value for element')");

I know that we are (n-1) * (n times), but why the division by 2?

It's only (n - 1) * n if you use a naive bubblesort. You can get a significant savings if you notice the following:

• After each compare-and-swap, the largest element you've encountered will be in the last spot you were at.

• After the first pass, the largest element will be in the last position; after the k^th pass, the k^th largest element will be in the k^th last position.

Thus you don't have to sort the whole thing every time: you only need to sort n - 2 elements the second time through, n - 3 elements the third time, and so on. That means that the total number of compare/swaps you have to do is (n - 1) + (n - 2) + .... This is an arithmetic series, and the equation for the total number of times is (n - 1)*n / 2.

Example: if the size of the list is N = 5, then you do 4 + 3 + 2 + 1 = 10 swaps -- and notice that 10 is the same as 4 * 5 / 2.

In addition to others' answers :

static:: will be computed using runtime information.

That means you can't use static:: in a class property because properties values :

Must be able to be evaluated at compile time and must not depend on run-time information.

class Foo {
    public $name = static::class;

}

$Foo = new Foo;
echo $Foo->name; // Fatal error

Using self::

class Foo {
    public $name = self::class;

}
$Foo = new Foo;
echo $Foo->name; // Foo

Please note that the Fatal error comment in the code i made doesn't indicate where the error happened, the error happened earlier before the object was instantiated as @Grapestain mentioned in the comments

Assuming you're interested in whether the variable has been explicitly assigned a value or not, the answer is "not really". There's absolutely no difference between a field (instance variable or class variable) which hasn't been explicitly assigned at all yet, and one which has been assigned its default value - 0, false, null etc.

Now if you know that once assigned, the value will never reassigned a value of null, you can use:

if (box != null) {
    box.removeFromCanvas();
}

(and that also avoids a possible NullPointerException) but you need to be aware that "a field with a value of null" isn't the same as "a field which hasn't been explicitly assigned a value". Null is a perfectly valid variable value (for non-primitive variables, of course). Indeed, you may even want to change the above code to:

if (box != null) {
    box.removeFromCanvas();
    // Forget about the box - we don't want to try to remove it again
    box = null;
}

The difference is also visible for local variables, which can't be read before they've been "definitely assigned" - but one of the values which they can be definitely assigned is null (for reference type variables):

// Won't compile
String x;
System.out.println(x);

// Will compile, prints null
String y = null;
System.out.println(y);

Quoting from the specification:

The getItem(key) method must return the current value associated with the given key. If the given key does not exist in the list associated with the object then this method must return null.

You should actually check against null.

if (localStorage.getItem("username") === null) {
  //...
}

Java has a LinkedList implementation, that you might wanna check out. You can download the JDK and it's sources at java.sun.com.

Why would UPDLOCK block selects? The Lock Compatibility Matrix clearly shows N for the S/U and U/S contention, as in No Conflict.

As for the HOLDLOCK hint the documentation states:

HOLDLOCK: Is equivalent to SERIALIZABLE. For more information, see SERIALIZABLE later in this topic.

...

SERIALIZABLE: ... The scan is performed with the same semantics as a transaction running at the SERIALIZABLE isolation level...

and the Transaction Isolation Level topic explains what SERIALIZABLE means:

No other transactions can modify data that has been read by the current transaction until the current transaction completes.

Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.

Therefore the behavior you see is perfectly explained by the product documentation:

• UPDLOCK does not block concurrent SELECT nor INSERT, but blocks any UPDATE or DELETE of the rows selected by T1
• HOLDLOCK means SERALIZABLE and therefore allows SELECTS, but blocks UPDATE and DELETES of the rows selected by T1, as well as any INSERT in the range selected by T1 (which is the entire table, therefore any insert).
• (UPDLOCK, HOLDLOCK): your experiment does not show what would block in addition to the case above, namely another transaction with UPDLOCK in T2:
  SELECT * FROM dbo.Test WITH (UPDLOCK) WHERE ...
• TABLOCKX no need for explanations

The real question is what are you trying to achieve? Playing with lock hints w/o an absolute complete 110% understanding of the locking semantics is begging for trouble...

After OP edit:

I would like to select rows from a table and prevent the data in that table from being modified while I am processing it.

The you should use one of the higher transaction isolation levels. REPEATABLE READ will prevent the data you read from being modified. SERIALIZABLE will prevent the data you read from being modified and new data from being inserted. Using transaction isolation levels is the right approach, as opposed to using query hints. Kendra Little has a nice poster exlaining the isolation levels.

Like the answer above but here is using bootstrap 3 names and colours:

/*css to add back colours for badges and make use of the colours*/_x000D_
.badge-default {_x000D_
  background-color: #999999;_x000D_
}_x000D_
_x000D_
.badge-primary {_x000D_
  background-color: #428bca;_x000D_
}_x000D_
_x000D_
.badge-success {_x000D_
  background-color: #5cb85c;_x000D_
}_x000D_
_x000D_
.badge-info {_x000D_
  background-color: #5bc0de;_x000D_
}_x000D_
_x000D_
.badge-warning {_x000D_
  background-color: #f0ad4e;_x000D_
}_x000D_
_x000D_
.badge-danger {_x000D_
  background-color: #d9534f;_x000D_
}

One alternative method is convert your List to array, iterate them and remove them directly from the List based on your logic.

List<String> myList = new ArrayList<String>(); // You can use either list or set

myList.add("abc");
myList.add("abcd");
myList.add("abcde");
myList.add("abcdef");
myList.add("abcdefg");

Object[] obj = myList.toArray();

for(Object o:obj)  {
    if(condition)
        myList.remove(o.toString());
}

Put a single listener on the table. When it gets a click from an input with a button that has a name of "edit" and value "edit", change its value to "modify". Get rid of the input's id (they aren't used for anything here), or make them all unique.

<script type="text/javascript">

function handleClick(evt) {
  var node = evt.target || evt.srcElement;
  if (node.name == 'edit') {
    node.value = "Modify";
  }
}

</script>

<table id="table1" border="1" onclick="handleClick(event);">
    <thead>
      <tr>
          <th>Select
    </thead>
    <tbody>
       <tr> 
           <td>
               <form name="f1" action="#" >
                <input id="edit1" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f2" action="#" >
                <input id="edit2" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f3" action="#" >
                <input id="edit3" type="submit" name="edit" value="Edit">
               </form>

   </tbody>

While it's a bit more verbose, you can accomplish what everyone else was recommending underscore/lodash for 2 years ago, by using Array.prototype.reduce.

var subset = ['color', 'height'].reduce(function(o, k) { o[k] = elmo[k]; return o; }, {});

This approach solves it from the other side: rather than take an object and pass property names to it to extract, take an array of property names and reduce them into a new object.

While it's more verbose in the simplest case, a callback here is pretty handy, since you can easily meet some common requirements, e.g. change the 'color' property to 'colour' on the new object, flatten arrays, etc. -- any of the things you need to do when receiving an object from one service/library and building a new object needed somewhere else. While underscore/lodash are excellent, well-implemented libs, this is my preferred approach for less vendor-reliance, and a simpler, more consistent approach when my subset-building logic gets more complex.

edit: es7 version of the same:

const subset = ['color', 'height'].reduce((a, e) => (a[e] = elmo[e], a), {});

edit: A nice example for currying, too! Have a 'pick' function return another function.

const pick = (...props) => o => props.reduce((a, e) => ({ ...a, [e]: o[e] }), {});

The above is pretty close to the other method, except it lets you build a 'picker' on the fly. e.g.

pick('color', 'height')(elmo);

What's especially neat about this approach, is you can easily pass in the chosen 'picks' into anything that takes a function, e.g. Array#map:

[elmo, grover, bigBird].map(pick('color', 'height'));
// [
//   { color: 'red', height: 'short' },
//   { color: 'blue', height: 'medium' },
//   { color: 'yellow', height: 'tall' },
// ]

no need for the padding or the corners.

here's a sample:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >
    <gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF"
        android:angle="270"/>
</shape>

Overload less than operator, then sort. This is an example I found off the web...

class MyData
{
public:
  int m_iData;
  string m_strSomeOtherData;
  bool operator<(const MyData &rhs) const { return m_iData < rhs.m_iData; }
};

std::sort(myvector.begin(), myvector.end());

You really should have multiple input, e.g. one for firstname, middle names, lastname and another one for age. If you want to have some fun though you could try:

>>> input_given="join smith 25"
>>> chars="".join([i for i in input_given if not i.isdigit()])
>>> age=input_given.translate(None,chars)
>>> age
'25'
>>> name=input_given.replace(age,"").strip()
>>> name
'join smith'

This would of course fail if there is multiple numbers in the input. a quick check would be:

assert(age in input_given)

and also:

assert(len(name)<len(input_given))

If you want to switch to a specific database on startup, try

/Applications/Postgres.app/Contents/Versions/9.5/bin/psql vigneshdb;

By default, Postgres runs on the port 5432. If it runs on another, make sure to pass the port in the command line.

/Applications/Postgres.app/Contents/Versions/9.5/bin/psql -p2345 vigneshdb;

By a simple alias, we can make it handy.

Create an alias in your .bashrc or .bash_profile

function psql()
{
    db=vigneshdb
    if [ "$1" != ""]; then
            db=$1
    fi
    /Applications/Postgres.app/Contents/Versions/9.5/bin/psql -p5432 $1
}

Run psql in command line, it will switch to default database; psql anotherdb, it will switch to the db with the name in argument, on startup.

In my case, I pushed several big (> 100Mb) files and then proceeded to remove them. But they were still in the history of my repo, so I had to remove them from it as well.

What did the trick was:

bfg -b 100M  # To remove all blobs from history, whose size is superior to 100Mb
git reflog expire --expire=now --all
git gc --prune=now --aggressive

Then, you need to push force on your branch:

git push origin <your_branch_name> --force

Note: bfg is a tool that can be installed on Linux and macOS using brew:

brew install bfg

You can try the following method :

 private void disableEditText(EditText editText) {
    editText.setFocusable(false);
    editText.setEnabled(false);
    editText.setCursorVisible(false);
    editText.setKeyListener(null);
    editText.setBackgroundColor(Color.TRANSPARENT); 
 }

Enabled EditText :

Disabled EditText :

It works for me and hope it helps you.

I had a similar task to do, but it contained some aspects that were not sufficiently covered by the other answers here:

• I had non-ASCII and (being a Windows user) non-UTF8-encoded characters (for the curious: German umlaute) in my commit messages and file names.

I did not try fast-export and hg-fast-export, since they require that you have Python and some Mercurial Python modules on your machine, which I didn't have.

I did try hg-init with TortoiseHG, and this answer gave me a good start. But it looked like it only converts the current branch, not all at once (*). So I read the hg-init docs and this blog post and added

[git]  
branch_bookmark_suffix=_bookmark

to my mercurial.ini, and did

hg bookmarks -r default master  
hg bookmarks -r my_branch my_branch_bookmark  
hg gexport

(Repeat the 2nd line for every branch you want to convert, and repeat it again if you should happen to do another commit before executing the 3rd line). This creates a folder git within .hg, which turns out to be a bare Git repo with all the exported branches. I could clone this repo and had a working copy as desired.

Or almost...

Running

git status

on my working copy showed all files with non-ASCII characters in their names as untracked files. So I continued researching and followed this advice:

git rm -rf --cached \*  
git add --all
git commit 

And finally the repo was ready to be pushed up to Bitbucket :-)

I also tried the Github importer as mentioned in this answer. I used Bitbucket as the source system, and Github did quite a good job, i.e. it converted all branches automatically. However, it showed '?'-characters for all non-ASCII characters in my commit messages (Web-UI and locally) and filenames (Web-UI only), and while I could fix the filenames as described above, I had no idea what to do with the commit messages, and so I'd prefer the hg-init approach. Without the encoding issue the Github importer would have been a perfect and fast solution (as long as you have a paid Github account or can tolerate that your repo is public for as long as it takes to pull it from Github to your local machine).

(*) So it looked like before I discovered that I have to bookmark all the branches I want to export. If you do and push to a bare (!) repo, like the linked answer says, you get all the branches.

The FormClosed Event is an Event that fires when the form closes. It is not used to actually close the form. You'll need to remove anything you've added there.

All you should have to do is add the following line to your button's event handler:

this.Close();

This is the better way that I use to create submit without loading in a form.

You can use some CSS to stylise the iframe the way you want.

A php result will be loaded into the iframe.

<form method="post" action="test.php" target="view">
  <input type="text" name="anyname" palceholder="Enter your name"/>
  <input type="submit" name="submit" value="submit"/>
  </form>
<iframe name="view" frameborder="0" style="width:100%">
  </iframe>

I have just started checking out Angular(so im quite sure there are other ways to get it done which are more optimum), and i came across this question while searching for examples of ng-repeat.

The requirement by the poser(with the update):

"...but my real requirement is display the items as shown below.."

looked real-world enough (and simple), so i thought ill give it a spin and attempt to get the exact desired structure.

angular.module('appTest', [])_x000D_
  .controller("repeatCtrl", function($scope) {_x000D_
    $scope.items = [{_x000D_
      Name: "Soap",_x000D_
      Price: "25",_x000D_
      Quantity: "10"_x000D_
    }, {_x000D_
      Name: "Bag",_x000D_
      Price: "100",_x000D_
      Quantity: "15"_x000D_
    }, {_x000D_
      Name: "Pen",_x000D_
      Price: "15",_x000D_
      Quantity: "13"_x000D_
    }];_x000D_
  })

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
_x000D_
<body ng-app="appTest">_x000D_
  <section ng-controller="repeatCtrl">_x000D_
    <table>_x000D_
      <thead>_x000D_
        <tr ng-repeat="item in items | limitTo:1">_x000D_
          <th ng-repeat="(key, val) in item">_x000D_
            {{key}}_x000D_
          </th>_x000D_
        </tr>_x000D_
      </thead>_x000D_
      <tbody>_x000D_
        <tr ng-repeat="item in items">_x000D_
          <td ng-repeat="(key, val) in item">_x000D_
            {{val}}_x000D_
          </td>_x000D_
        </tr>_x000D_
      </tbody>_x000D_
    </table>_x000D_
  </section>_x000D_
</body>

The limitTo:(n) filter is the key. Im still not sure if having multiple ng-repeat is an optimum way to go about it, but can't think of another alternative currently.

Each database's implementation but you can probably guess that they all solve common problems in more or less the same way. If you are using MSSQL have a look at the execution plan that is generated. You can do this by turning on the profiler and executions plans. This will give you a text version when you run the command.

I am not sure what version of MSSQL you are using but you can get a graphical one in SQL Server 2000 in the query analyzer. I am sure that this functionality is lurking some where in SQL Server Studio Manager in later versions.

Have a look at the exeuction plan. As far as possible avoid table scans unless of course your table is small in which case a table scan is faster than using an index. Read up on the different join operations that each different scenario produces.

Try with this code:

InputStream in = address.openStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder result = new StringBuilder();
String line;
while((line = reader.readLine()) != null) {
    result.append(line);
}
System.out.println(result.toString());

Eran's answer is good, but I would append to that. You need to watch any interactivity that is not inline to the object (that is, if an onclick event calls a function, it still will), but if there is some javascript or jQuery event handling attached to that ID, it will be basically abandoned:

$("#myId").on("click", function() {});

If the ID is now changed to #myID123, the function attached above will no longer function correctly from my experience.

You can pass the container by reference in order to modify it in the function. What other answers haven’t addressed is that std::vector does not have a push_front member function. You can use the insert() member function on vector for O(n) insertion:

void do_something(int el, std::vector<int> &arr){
    arr.insert(arr.begin(), el);
}

Or use std::deque instead for amortised O(1) insertion:

void do_something(int el, std::deque<int> &arr){
    arr.push_front(el);
}

First, gather optimiser stats on the table (if you haven't already):

begin
   dbms_stats.gather_table_stats('MYSCHEMA','MYTABLE');
end;
/

WARNING: As Justin says in his answer, gathering optimiser stats affects query optimisation and should not be done without due care and consideration!

Then find the number of blocks occupied by the table from the generated stats:

select blocks, empty_blocks, num_freelist_blocks
from   all_tables
where  owner = 'MYSCHEMA'
and    table_name = 'MYTABLE';

• The total number of blocks allocated to the table is blocks + empty_blocks + num_freelist_blocks.

• blocks is the number of blocks that actually contain data.

Multiply the number of blocks by the block size in use (usually 8KB) to get the space consumed - e.g. 17 blocks x 8KB = 136KB.

To do this for all tables in a schema at once:

begin
    dbms_stats.gather_schema_stats ('MYSCHEMA');
end;
/

select table_name, blocks, empty_blocks, num_freelist_blocks
from   user_tables;

Note: Changes made to the above after reading this AskTom thread

this is what I use for a cross-platform code:

#ifdef _WIN32
#include <Windows.h>
#else
#include <unistd.h>
#endif

int main()
{
  pollingDelay = 100
  //do stuff

  //sleep:
  #ifdef _WIN32
  Sleep(pollingDelay);
  #else
  usleep(pollingDelay*1000);  /* sleep for 100 milliSeconds */
  #endif

  //do stuff again
  return 0;
}

left:auto;

This will default the left back to the browser default.

So if you have your Markup/CSS as:

<div class="myClass"></div>

.myClass
{
  position:absolute;
  left:0;
}

When setting RTL, you could change to:

<div class="myClass rtl"></div>

.myClass
{
  position:absolute;
  left:0;
}
.myClass.rtl
{
  left:auto;
  right:0;
}

RoflcoptrException's answer should do the trick,but for some reason it did not work for me, So I am posting the solution which worked for me, hope it helps someone

<ListView 
android:listSelector="@android:color/transparent" 
android:cacheColorHint="@android:color/transparent"
/>

Ok, here's a basic join query that gets the correct records:

   int[] selectedRolesArr = GetSelectedRoles();
    if( selectedRolesArr != null && selectedRolesArr.Length > 0 ) 
    {

    //this join version requires the use of distinct to prevent muliple records
        //being returned for users with more than one company role.
    IQueryable retVal = (from u in context.Users
                        join c in context.CompanyRolesToUsers
                          on u.Id equals c.UserId
                        where u.LastName.Contains( "fra" ) &&
                            selectedRolesArr.Contains( c.CompanyRoleId )
                        select  u).Distinct();
}

But here's the code that most easily integrates with the algorithm that we already had in place:

int[] selectedRolesArr = GetSelectedRoles(); 
if ( useAnd ) 
       { 
          predicateAnd = predicateAnd.And( u => (from c in context.CompanyRolesToUsers 
                       where selectedRolesArr.Contains(c.CompanyRoleId) 
                       select c.UserId).Contains(u.Id)); 
        } 
        else 
        { 
           predicateOr = predicateOr.Or( u => (from c in context.CompanyRolesToUsers 
                          where selectedRolesArr.Contains(c.CompanyRoleId) 
                         select c.UserId).Contains(u.Id) ); 
        } 

which is thanks to a poster at the LINQtoSQL forum

select name, value 
from( select name, value, ROW_NUMBER() OVER(PARTITION BY name ORDER BY value desc) as rn
from out_pumptable ) as a
where rn = 1

It appears that you are using the default route which is defined as this:

routes.MapRoute(
    name: "Default",
    url: "{controller}/{action}/{id}",
    defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);

The key part of that route is the {id} piece. If you look at your action method, your parameter is k instead of id. You need to change your action method to this so that it matches the route parameter:

// change int k to int id
public ActionResult DetailsData(int id)

If you wanted to leave your parameter as k, then you would change the URL to be:

http://localhost:7317/Employee/DetailsData?k=4

You also appear to have a problem with your connection string. In your web.config, you need to change your connection string to this (provided by haim770 in another answer that he deleted):

<connectionStrings>
  <add name="EmployeeContext"
       connectionString="Server=.;Database=mytry;integrated security=True;"
       providerName="System.Data.SqlClient" />
</connectionStrings>

On Windows PC You may not need to do anything else than finding out your IPv4 Address using "ipconfig" command.

• Step 1 : Connect your phone to PC using USB cable.
• Step 2 : Use command 'ipconfig' to find out your IPv4 Address (External IP of the Router) e.g 192.168.1.5 in my case.
• Step 3: Just access "192.168.1.5:8080" from your phone browser. It works !

Other Env Details : Windows 7, Google Nexus 4 (4.2.2), Tomcat Server, Grails Application.

You should also make sure that you have the permission to access internet in AndroidManifest file :

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

Try HostingEnvironment.MapPath, which is static.

See this SO question for confirmation that HostingEnvironment.MapPath returns the same value as Server.MapPath: What is the difference between Server.MapPath and HostingEnvironment.MapPath?

This is using the :hover pseudoelement in CSS3.

HTML:

<div id="wrapper">
    <img src="http://placehold.it/300x200" class="hover" />
    <p class="text">text</p>
</div>?

CSS:

#wrapper .text {
position:relative;
bottom:30px;
left:0px;
visibility:hidden;
}

#wrapper:hover .text {
visibility:visible;
}

?Demo HERE.

This instead is a way of achieving the same result by using jquery:

HTML:

<div id="wrapper">
    <img src="http://placehold.it/300x200" class="hover" />
    <p class="text">text</p>
</div>?

CSS:

#wrapper p {
position:relative;
bottom:30px;
left:0px;
visibility:hidden;
}

jquery code:

$('.hover').mouseover(function() {
  $('.text').css("visibility","visible");
});

$('.hover').mouseout(function() {
  $('.text').css("visibility","hidden");
});

You can put the jquery code where you want, in the body of the HTML page, then you need to include the jquery library in the head like this:

<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>

You can see the demo HERE.

When you want to use it on your website, just change the <img src /> value and you can add multiple images and captions, just copy the format i used: insert image with class="hover" and p with class="text"

What I do is create a view that performs the same select as the table variable and link that view into the second view. So a view can select from another view. This achieves the same result

Please try the below query. Use sys.columns to get the details :-

SELECT c.name AS ColName, t.name AS TableName
FROM sys.columns c
    JOIN sys.tables t ON c.object_id = t.object_id
WHERE c.name LIKE '%MyCol%';

• Remove the file from the index, but keep it versioned and left with uncommitted changes in working copy:

  git reset head <file>
  

• Reset the file to the last state from HEAD, undoing changes and removing them from the index:

  git reset HEAD <file>
  git checkout <file>
  
  # If you have a `<branch>` named like `<file>`, use:
  git checkout -- <file>
  

  This is needed since git reset --hard HEAD won't work with single files.

• Remove <file> from index and versioning, keeping the un-versioned file with changes in working copy:

  git rm --cached <file>
  

• Remove <file> from working copy and versioning completely:

  git rm <file>

You can easily do this with the normal "Time" data type - just change the format!

Excels time/date format is simply 1.0 equals 1 full day (starting on 1/1/1900). So 36 hours would be 1.5. If you change the format to [h]:mm, you'll see 36:00.

Therefore, if you want to work with durations, you can simply use subtraction, e.g.

A1: Start:           36:00 (=1.5)
A2: End:             60:00 (=2.5) 
A3: Duration: =A2-A1 24:00 (=1.0)

I used CIFAR10 format instead of STL10 and code came out like

filename_queue = tf.train.string_input_producer(filenames)
read_input = read_cifar10(filename_queue)
with tf.Session() as sess:       
    tf.train.start_queue_runners(sess=sess)
    result = sess.run(read_input.uint8image)        
img = Image.fromarray(result, "RGB")    
img.save('my.jpg')

The snippet is identical with mttk and Rosa Gronchi, but Somehow I wasn't able to show the image during run-time, so I saved as the JPG file.

Another way I haven't seen listed yet is to set your sentinel value ahead of time. This method takes advantage of Python's lazy evaluation, in which you don't always have to provide an else statement. Example:

startingpoint = 'blah'
if len(sys.argv) >= 2:
  startingpoint = sys.argv[1]

Or if you're going syntax CRAZY you could use Python's ternary operator:

startingpoint = sys.argv[1] if len(sys.argv) >= 2 else 'blah'

How about using assign?

functionReturningTwoValues <- function(a, b) {
  assign(a, 1, pos=1)
  assign(b, 2, pos=1)
}

You can pass the names of the variable you want to be passed by reference.

> functionReturningTwoValues('a', 'b')
> a
[1] 1
> b
[1] 2

If you need to access the existing values, the converse of assign is get.

If the functions are re-written with completely different variables and we call id on them, it then illustrates the point well. I didn't get this at first and read jfs' post with the great explanation, so I tried to understand/convince myself:

def f(y, z):
    y = 2
    z.append(4)
    print ('In f():             ', id(y), id(z))

def main():
    n = 1
    x = [0,1,2,3]
    print ('Before in main:', n, x,id(n),id(x))
    f(n, x)
    print ('After in main:', n, x,id(n),id(x))

main()
Before in main: 1 [0, 1, 2, 3]   94635800628352 139808499830024
In f():                          94635800628384 139808499830024
After in main: 1 [0, 1, 2, 3, 4] 94635800628352 139808499830024

z and x have the same id. Just different tags for the same underlying structure as the article says.

Answer sans superfluous edge cases:

const thingsWithoutNulls = things.reduce((acc, thing) => {
  if (thing !== null) {
    acc.push(thing);
  }
  return acc;
}, [])

One can simply use

INSERT INTO MY_TABLE(MY_TIMESTAMP_FIELD)
VALUES (TIMESTAMP '2019-02-15 13:22:11.871+02:00');

This way you won't have to worry about date format string, just use default timestamp format.

Works with Oracle 11, have no idea if it does for earlier Oracle versions.

Here's a function that will use the dom instead of string concatenation.

function createTable(tableData) {
  var table = document.createElement('table');
  var tableBody = document.createElement('tbody');

  tableData.forEach(function(rowData) {
    var row = document.createElement('tr');

    rowData.forEach(function(cellData) {
      var cell = document.createElement('td');
      cell.appendChild(document.createTextNode(cellData));
      row.appendChild(cell);
    });

    tableBody.appendChild(row);
  });

  table.appendChild(tableBody);
  document.body.appendChild(table);
}

createTable([["row 1, cell 1", "row 1, cell 2"], ["row 2, cell 1", "row 2, cell 2"]]);

Partially based on Mohsen's answer (the added first condition covers the case where the child is hidden before the parent):

jQuery.fn.isChildOverflowing = function (child) {
  var p = jQuery(this).get(0);
  var el = jQuery(child).get(0);
  return (el.offsetTop < p.offsetTop || el.offsetLeft < p.offsetLeft) ||
    (el.offsetTop + el.offsetHeight > p.offsetTop + p.offsetHeight || el.offsetLeft + el.offsetWidth > p.offsetLeft + p.offsetWidth);
};

Then just do:

jQuery('#parent').isChildOverflowing('#child');

Fast and Easy

double[] anArray = new Random().doubles(10).toArray();

if qs.count()==1:
        print('cart id exists')
        if ....

else:    
        return render(request,"carts/home.html",{})

Such type of code will also return you the same error this is because of the intents as the return statement should be for else not for if statement.

above code can be changed to

if qs.count()==1:
        print('cart id exists')
        if ....

else:   

return render(request,"carts/home.html",{})

This may solve such issues

It's because there can only be one definition of A::a that all the translation units use.

If you performed static int a = 3; in a class in a header included in all a translation units then you'd get multiple definitions. Therefore, non out-of-line definition of a static is forcibly made a compiler error.

Using static inline or static const remedies this. static inline only concretises the symbol if it is used in the translation unit and ensures the linker only selects and leaves one copy if it's defined in multiple translation units due to it being in a comdat group. const at file scope makes the compiler never emit a symbol because it's always substituted immediately in the code unless extern is used, which is not permitted in a class.

One thing to note is static inline int b; is treated as a definition whereas static const int b or static const A b; are still treated as a declaration and must be defined out-of-line if you don't define it inside the class. Interestingly static constexpr A b; is treated as a definition, whereas static constexpr int b; is an error and must have an initialiser (this is because they now become definitions and like any const/constexpr definition at file scope, they require an initialiser which an int doesn't have but a class type does because it has an implicit = A() when it is a definition -- clang allows this but gcc requires you to explicitly initialise or it is an error. This is not a problem with inline instead). static const A b = A(); is not allowed and must be constexpr or inline in order to permit an initialiser for a static object with class type i.e to make a static member of class type more than a declaration. So yes in certain situations A a; is not the same as explicitly initialising A a = A(); (the former can be a declaration but if only a declaration is allowed for that type then the latter is an error. The latter can only be used on a definition. constexpr makes it a definition). If you use constexpr and specify a default constructor then the constructor will need to be constexpr

#include<iostream>

struct A
{
    int b =2;
    mutable int c = 3; //if this member is included in the class then const A will have a full .data symbol emitted for it on -O0 and so will B because it contains A.
    static const int a = 3;
};

struct B {
    A b;
    static constexpr A c; //needs to be constexpr or inline and doesn't emit a symbol for A a mutable member on any optimisation level
};

const A a;
const B b;

int main()
{
    std::cout << a.b << b.b.b;
    return 0;
}

A static member is an outright file scope declaration extern int A::a; (which can only be made in the class and out of line definitions must refer to a static member in a class and must be definitions and cannot contain extern) whereas a non-static member is part of the complete type definition of a class and have the same rules as file scope declarations without extern. They are implicitly definitions. So int i[]; int i[5]; is a redefinition whereas static int i[]; int A::i[5]; isn't but unlike 2 externs, the compiler will still detect a duplicate member if you do static int i[]; static int i[5]; in the class.

<VirtualHost *:80>

Should work. The first entry will become the default if you don't get an explicit match. So if you had app.otherexample.com point to it, it would be caught be app1.example.com.

The way to reinstall Homebrew is completely remove it and start over. The Homebrew FAQ has a link to a shell script to uninstall homebrew.

If the only thing you've installed in /usr/local is homebrew itself, you can just rm -rf /usr/local/* /usr/local/.git to clear it out. But /usr/local/ is the standard Unix directory for all extra binaries, not just Homebrew, so you may have other things installed there. In that case uninstall_homebrew.sh is a better bet. It is careful to only remove homebrew's files and leave the rest alone.

That's right. 'list index out of range' most likely means you are referring to n-th element of the list, while the length of the list is smaller than n.

The location has changed from Java 6 (provided by Apple) to Java 7 and onwards (provided by Oracle). The best generic way to find this out is to run

/usr/libexec/java_home

This is the natively supported way to find out both the path to the default Java installation as well as all alternative ones present.

If you check out its help text (java_home -h), you'll see that you can use this command to reliably start a Java program on OS X (java_home --exec ...), with the ability to explicitly specify the desired Java version and architecture, or even request the user to install it if missing.

A more pedestrian approach, but one which will help you trace specifically which Java installation the command java resolves into, goes like this:

1. run

   which java
   

2. if that gives you something like /usr/bin/java, which is a symbolic link to the real location, run

   ls -l `which java`
   

   On my system, this outputs

   /usr/bin/java -> /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/bin/java
   

   and therefrom you can read the Java home directory;

3. if usr/bin/java points to another symbolic link, recursively apply the same approach with

   ls -l <whatever the /usr/bin/java symlink points to>
   

An important variation is the setup you get if you start by installing Apple's Java and later install Oracle's. In that case Step 2 above will give you

/usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Commands/java

and that particular java binary is a stub which will resolve the actual java command to call by consulting the JAVA_HOME environment variable and, if it's not set or doesn't point to a Java home directory, will fall back to calling java_home. It is important to have this in mind when debugging your setup.

This error could be thrown in the following situation as well.

You want to checkout branch called feature from remote repository but the error is thrown because you already have branch called feature/<feature_name> in your local repository.

Simply checkout the feature branch under a different name:

git checkout -b <new_branch_name> <remote>/feature

Move:

var k = Math.pow(10, i);

above

var j = k / 10;

xCode 7.3.1 iOS 9.3.2

 _siteLabel.layer.masksToBounds = true;
  _siteLabel.layer.cornerRadius = 8;

A small modification to Ken Williams' answer, adding optional params na.rm and return_multiple.

Unlike the answers relying on names(), this answer maintains the data type of x in the returned value(s).

stat_mode <- function(x, return_multiple = TRUE, na.rm = FALSE) {
  if(na.rm){
    x <- na.omit(x)
  }
  ux <- unique(x)
  freq <- tabulate(match(x, ux))
  mode_loc <- if(return_multiple) which(freq==max(freq)) else which.max(freq)
  return(ux[mode_loc])
}

To show it works with the optional params and maintains data type:

foo <- c(2L, 2L, 3L, 4L, 4L, 5L, NA, NA)
bar <- c('mouse','mouse','dog','cat','cat','bird',NA,NA)

str(stat_mode(foo)) # int [1:3] 2 4 NA
str(stat_mode(bar)) # chr [1:3] "mouse" "cat" NA
str(stat_mode(bar, na.rm=T)) # chr [1:2] "mouse" "cat"
str(stat_mode(bar, return_mult=F, na.rm=T)) # chr "mouse"

Thanks to @Frank for simplification.

Supported in latest chrome, opera and safari, you can do this:

-webkit-clip-path: inset(0 0 0 0 round 100px);
clip-path: inset(0 0 0 0 round 100px);

You should definitely check out the tool http://bennettfeely.com/clippy/!

The previous answer is pretty good, but I also wanted to mention that there is a fixed layout equivalent for grids, you just need to write minmax(0, 1fr) instead of 1fr as your track size.

based on Sam Holder's answer, you could make an extension method for that

namespace adonet.extensions
{
  public static class AdonetExt
  {
    public static int GetInt32(this SqlDataReader reader, string columnName)
    {
      return reader.GetInt32(reader.GetOrdinal(columnName));
    }
  }
}

and use it like this

using adonet.extensions;

//...

int farmsize = reader.GetInt32("farmsize");

assuming there is no GetInt32(string) already in SqlDataReader - if there is any, just use some other method name instead

Optimized version of Jens' answere with null-safety and fallback-type.

@NonNull
static String getMimeType(@NonNull File file) {
    String type = null;
    final String url = file.toString();
    final String extension = MimeTypeMap.getFileExtensionFromUrl(url);
    if (extension != null) {
        type = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension.toLowerCase());
    }
    if (type == null) {
        type = "image/*"; // fallback type. You might set it to */*
    }
    return type;
}

Important: getFileExtensionFromUrl() only works with lowercase!

Update (19.03.2018)

Bonus: Above methods as a less verbose Kotlin extension function:

fun File.getMimeType(fallback: String = "image/*"): String {
    return MimeTypeMap.getFileExtensionFromUrl(toString())
            ?.run { MimeTypeMap.getSingleton().getMimeTypeFromExtension(toLowerCase()) }
            ?: fallback // You might set it to */*
}

        #region even and odd numbers
        for (int x = 0; x <= 50; x = x + 2)
        {

            int y = 1;
            y = y + x;
            if (y < 50)
            {
                Console.WriteLine("Odd number is #{" + x + "} : even number is #{" + y + "} order by Asc");
                Console.ReadKey();
            }
            else
            {
                Console.WriteLine("Odd number is #{" + x + "} : even number is #{0} order by Asc");
                Console.ReadKey();
            }

        }

        //order by desc

        for (int z = 50; z >= 0; z = z - 2)
        {
            int w = z;
            w = w - 1;
            if (w > 0)
            {
                Console.WriteLine("odd number is {" + z + "} : even number is {" + w + "} order by desc");
                Console.ReadKey();
            }
            else
            {
                Console.WriteLine("odd number is {" + z + "} : even number is {0} order by desc");
                Console.ReadKey();
            }
        }

What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.

I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)

With @Lob I always end up with a LONGTEXTin MySQL.

To get TEXT I declare it that way (JPA 2.0):

@Column(columnDefinition = "TEXT")
private String text

Find this better, because I can directly choose which Text-Type the column will have in database.

For columnDefinition it is also good to read this.

EDIT: Please pay attention to Adam Siemions comment and check the database engine you are using, before applying columnDefinition = "TEXT".

For whom want to install ext-dom on php 7.1 and up run this command:

sudo apt install php-xml

I think the Key and IV used for encryption using command line and decryption using your program are not same.

Please note that when you use the "-k" (different from "-K"), the input given is considered as a password from which the key is derived. Generally in this case, there is no need for the "-iv" option as both key and password will be derived from the input given with "-k" option.

It is not clear from your question, how you are ensuring that the Key and IV are same between encryption and decryption.

In my suggestion, better use "-K" and "-iv" option to explicitly specify the Key and IV during encryption and use the same for decryption. If you need to use "-k", then use the "-p" option to print the key and iv used for encryption and use the same in your decryption program.

More details can be obtained at https://www.openssl.org/docs/manmaster/apps/enc.html

Use JSON to transfer data types (arrays and objects) between client and server.

In PHP:

• json_encode
• json_decode

In JavaScript:

• JSON.stringify
• JSON.parse

PHP:

echo json_encode($id_numbers);

JavaScript:

id_numbers = JSON.parse(msg);

As Wolfgang mentioned, you can give a fourth parameter to jQuery to automatically decode JSON for you.

id_numbers = new Array();
$.ajax({
    url:"Example.php",
    type:"POST",
    success:function(msg){
        id_numbers = msg;
    },
    dataType:"json"
});

In most browsers, you can use a javascript variable instead of using document.getElementById. Say your html body content is like this:

<section id="mySection"> Hello </section>

Then you can just refer to mySection as a variable in javascript:

mySection.innerText += ', world'
// same as: document.getElementById('mySection').innerText += ', world'

See this snippet:

mySection.innerText += ', world!'

<section id="mySection"> Hello </section>

The easiest way to do it is to make the display an inline block

<div id='page' style='width: 600px'>
  <h1 style='border:2px black solid; font-size:42px; display: inline-block;'>Title</h1>
</div>

if you do this it should work

Had same issue with Firefox. I switched over to Chrome with options and all has been fine since.

ChromeOptions options = new ChromeOptions();
 options.AddArgument("no-sandbox");

 ChromeDriver driver = new ChromeDriver(ChromeDriverService.CreateDefaultService(), options, TimeSpan.FromMinutes(3));
 driver.Manage().Timeouts().PageLoad.Add(System.TimeSpan.FromSeconds(30));

On bulk inserts

Inspired by this post and by the Stack Overflow question that led me here -- Is it possible to insert multiple rows at a time in an SQLite database? -- I've posted my first Git repository:

https://github.com/rdpoor/CreateOrUpdate

which bulk loads an array of ActiveRecords into MySQL, SQLite or PostgreSQL databases. It includes an option to ignore existing records, overwrite them or raise an error. My rudimentary benchmarks show a 10x speed improvement compared to sequential writes -- YMMV.

I'm using it in production code where I frequently need to import large datasets, and I'm pretty happy with it.

if you want secure encryption:

for python 2, you should use keyczar http://www.keyczar.org/

for python 3, until keyczar is available, i have written simple-crypt http://pypi.python.org/pypi/simple-crypt

both these will use key strengthening which makes them more secure than most other answers here. and since they're so easy to use you might want to use them even when security is not critical...

Both Date and moment will parse the input string in the local time zone of the browser by default. However Date is sometimes inconsistent with this regard. If the string is specifically YYYY-MM-DD, using hyphens, or if it is YYYY-MM-DD HH:mm:ss, it will interpret it as local time. Unlike Date, moment will always be consistent about how it parses.

The correct way to parse an input moment as UTC in the format you provided would be like this:

moment.utc('07-18-2013', 'MM-DD-YYYY')

Refer to this documentation.

If you want to then format it differently for output, you would do this:

moment.utc('07-18-2013', 'MM-DD-YYYY').format('YYYY-MM-DD')

You do not need to call toString explicitly.

Note that it is very important to provide the input format. Without it, a date like 01-04-2013 might get processed as either Jan 4th or Apr 1st, depending on the culture settings of the browser.

The first arg that you give to grep needs to evaluate as true or false to indicate whether there was a match. So it should be:

# note that grep returns a list, so $matched needs to be in brackets to get the 
# actual value, otherwise $matched will just contain the number of matches
if (my ($matched) = grep $_ eq $match, @array) {
    print "found it: $matched\n";
}

If you need to match on a lot of different values, it might also be worth for you to consider putting the array data into a hash, since hashes allow you to do this efficiently without having to iterate through the list.

# convert array to a hash with the array elements as the hash keys and the values are simply 1
my %hash = map {$_ => 1} @array;

# check if the hash contains $match
if (defined $hash{$match}) {
    print "found it\n";
}

I know there are already many similar answers here, and mine is not much different, but I will post it anyway because it deals with a specific case/issue.

When dealing with the facebook Graph API in PHP you sometimes get an error, but immediately re-trying the same thing will give a positive result (for various magical Internet reasons that are beyond the scope of this question). In this case there is no need to fix any error, but to simply try again because there was some kind of "facebook error".

This code is used immediately after creating a facebook session:

//try more than once because sometimes "facebook error"
$attempt = 3;
while($attempt-- > 0)
{
    // To validate the session:
    try 
    {
        $facebook_session->validate();
        $attempt = 0;
    } 
    catch (Facebook\FacebookRequestException $ex)
    {
        // Session not valid, Graph API returned an exception with the reason.
        if($attempt <= 0){ echo $ex->getMessage(); }
    } 
    catch (\Exception $ex) 
    {
        // Graph API returned info, but it may mismatch the current app or have expired.
        if($attempt <= 0){ echo $ex->getMessage(); }
    }
}

Also, by having the for loop count down to zero ($attempt--) it makes it pretty easy to change the number of attempts in the future.

I think what you are looking for is:

list(im.getdata())

or, if the image is too big to load entirely into memory, so something like that:

for pixel in iter(im.getdata()):
    print pixel

from PIL documentation:

getdata

im.getdata() => sequence

Returns the contents of an image as a sequence object containing pixel values. The sequence object is flattened, so that values for line one follow directly after the values of line zero, and so on.

Note that the sequence object returned by this method is an internal PIL data type, which only supports certain sequence operations, including iteration and basic sequence access. To convert it to an ordinary sequence (e.g. for printing), use list(im.getdata()).

Edit: See Matt Diamond's comment below.

Got it! Try this:

map.fitBounds(bounds);
var listener = google.maps.event.addListener(map, "idle", function() { 
  if (map.getZoom() > 16) map.setZoom(16); 
  google.maps.event.removeListener(listener); 
});

Modify to your needs.

Java 8 and above

Using Java 8+ lambda expressions, if you have a class or interface with only a single abstract method (sometimes called a SAM type), for example:

public interface MyInterface {
    String doSomething(int param1, String param2);
}

then anywhere where MyInterface is used, you can substitute a lambda expression:

class MyClass {
    public MyInterface myInterface = (p1, p2) -> { return p2 + p1; };
}

For example, you can create a new thread very quickly:

new Thread(() -> someMethod()).start();

And use the method reference syntax to make it even cleaner:

new Thread(this::someMethod).start();

Without lambda expressions, these last two examples would look like:

new Thread(new Runnable() { someMethod(); }).start();

Before Java 8

A common pattern would be to 'wrap' it within an interface, like Callable, for example, then you pass in a Callable:

public T myMethod(Callable<T> func) {
    return func.call();
}

This pattern is known as the Command Pattern.

Keep in mind you would be best off creating an interface for your particular usage. If you chose to go with callable, then you'd replace T above with whatever type of return value you expect, such as String.

In response to your comment below you could say:

public int methodToPass() { 
        // do something
}

public void dansMethod(int i, Callable<Integer> myFunc) {
       // do something
}

then call it, perhaps using an anonymous inner class:

dansMethod(100, new Callable<Integer>() {
   public Integer call() {
        return methodToPass();
   }
});

Keep in mind this is not a 'trick'. It's just java's basic conceptual equivalent to function pointers.

I fixed this problem with sql command line:

connect system/<password>
alter system set processes=300 scope=spfile;
alter system set sessions=300 scope=spfile;

Restart database.

The following should work just fine:

KeychainItemWrapper *keychainItem = [[KeychainItemWrapper alloc] initWithIdentifier:@"YourAppLogin" accessGroup:nil];
[keychainItem setObject:@"password you are saving" forKey:kSecValueData]; 
[keychainItem setObject:@"username you are saving" forKey:kSecAttrAccount];

My code snippet:

environment {
    ...
    ...
    git_repo = 'my-repo'
}

stage ('Update Helm Chart') {
    steps {
        echo 'Updating values.xml file with latest Docker image tag'

        withCredentials([usernamePassword(credentialsId: '6bgg7dd45-c65f13-4275-a96ddehdv67gdr', usernameVariable: 'GIT_USER', passwordVariable: 'GIT_PASS')]) {
            sh '''
                git checkout ${git_branch}
                ...
                ...
                git remote set-url origin "http://${GIT_USER}:${GIT_PASS}@git.example.com/scm/${git_repo}.git"
                git push origin ${git_branch}
            '''
        }
    }
}

My Git user name was [email protected] so i had to first URL encode @ to %40. After URL encoding, my user name became deploy.user%40example.com.

However, i was still getting the following error:

fatal: repository 'http://****:****@git.example.com/scm/my-repo.git/' not found

After some trial and error, i found that if i don't use variable for user name and instead hard-code it, it works.

git remote set-url origin "http://deploy.user%40example.com:${GIT_PASS}@git.example.com/scm/${git_repo}.git"

For your specific question about WordPress, use the following code:

if (!is_dir(ABSPATH . 'wp-content/uploads')) wp_mkdir_p(ABSPATH . 'wp-content/uploads');

Function Reference: WordPress wp_mkdir_p. ABSPATH is the constant that returns WordPress working directory path.

The following code is for PHP in general.

if (!is_dir('path/to/directory')) mkdir('path/to/directory', 0777, true);

Function reference: PHP is_dir()

This is a block element, in order for it to be able to receive focus, you need to add tabindex attribute to it, as in

<div id="myID" tabindex="1"></div>

Tabindex will allow this element to receive focus. Use tabindex="-1" (or indeed, just get rid of the attribute alltogether) to disallow this behaviour.

And then you can simply

if ($("#myID").is(":focus")) {...}

Or use the

$(document.activeElement)

As been suggested previously.

Unless you have more style sheets than that, you've messed up your break points:

#1 (max-width: 700px)
#2 (min-width: 701px) and (max-width: 900px)
#3 (max-width: 901px)

The 3rd media query is probably meant to be min-width: 901px. Right now, it overlaps #1 and #2, and only controls the page layout by itself when the screen is exactly 901px wide.

Edit for updated question:

(max-width: 640px)
(max-width: 800px)
(max-width: 1024px)
(max-width: 1280px)

Media queries aren't like catch or if/else statements. If any of the conditions match, then it will apply all of the styles from each media query it matched. If you only specify a min-width for all of your media queries, it's possible that some or all of the media queries are matched. In your case, a device that's 640px wide matches all 4 of your media queries, so all for style sheets are loaded. What you are most likely looking for is this:

(max-width: 640px)
(min-width: 641px) and (max-width: 800px)
(min-width: 801px) and (max-width: 1024px)
(min-width: 1025px)

Now there's no overlap. The styles will only apply if the device's width falls between the widths specified.

The FETCH_HEAD is a reference to the tip of the last fetch, whether that fetch was initiated directly using the fetch command or as part of a pull. The current value of FETCH_HEAD is stored in the .git folder in a file named, you guessed it, FETCH_HEAD.

So if I issue:

git fetch https://github.com/ryanmaxwell/Fragaria

FETCH_HEAD may contain

3cfda7cfdcf9fb78b44d991f8470df56723658d3        https://github.com/ryanmaxwell/Fragaria

If I have the remote repo configured as a remote tracking branch then I can follow my fetch with a merge of the tracking branch. If I don't I can merge the tip of the last fetch directly using FETCH_HEAD.

git merge FETCH_HEAD

Late answer, but for python>=3.6 you can use dload, i.e.:

import dload
dload.save("http://www.digimouth.com/news/media/2011/09/google-logo.jpg")

if you need the image as bytes, use:

As an option, you can create abstract test class covering logic inside abstract class and extend it for each subclass test. So that in this way you can ensure this logic will be tested for each child separately.

if you in psql just type

set schema 'temp';

and after that \d shows all relations in "temp

While the selected answer is strictly correct, I believe I understand what the OP is trying to get at here as I had a similar issue.

I had a TimeSpan which I wished to display in a grid control (as just hh:mm) but the grid didn't appear to understand TimeSpan, only DateTime . The OP has a similar scenario where only the TimeSpan is the relevant part but didn't consider the necessity of adding the DateTime reference point.

So, as indicated above, I simply added DateTime.MinValue (though any date will do) which is subsequently ignored by the grid when it renders the timespan as a time portion of the resulting date.

You can't use a variable in an IN clause - you need to use dynamic SQL, or use a function (TSQL or CLR) to convert the list of values into a table.

Dynamic SQL example:

DECLARE @ExcludedList VARCHAR(MAX)
    SET @ExcludedList = 3 + ',' + 4 + ',' + '22'

DECLARE @SQL NVARCHAR(4000)
    SET @SQL = 'SELECT * FROM A WHERE Id NOT IN (@ExcludedList) '

 BEGIN

   EXEC sp_executesql @SQL '@ExcludedList VARCHAR(MAX)' @ExcludedList

 END

My understanding is that interfaces are not that necessary in dynamic languages like Python. In Java (or C++ with its abstract base class) interfaces are means for ensuring that e.g. you're passing the right parameter, able to perform set of tasks.

E.g. if you have observer and observable, observable is interested in subscribing objects that supports IObserver interface, which in turn has notify action. This is checked at compile time.

In Python, there is no such thing as compile time and method lookups are performed at runtime. Moreover, one can override lookup with __getattr__() or __getattribute__() magic methods. In other words, you can pass, as observer, any object that can return callable on accessing notify attribute.

This leads me to the conclusion, that interfaces in Python do exist - it's just their enforcement is postponed to the moment in which they are actually used

Wikipedia has a very good answer http://en.wikipedia.org/wiki/Universally_unique_identifier#Collisions

the number of random version 4 UUIDs which need to be generated in order to have a 50% probability of at least one collision is 2.71 quintillion, computed as follows:

...

This number is equivalent to generating 1 billion UUIDs per second for about 85 years, and a file containing this many UUIDs, at 16 bytes per UUID, would be about 45 exabytes, many times larger than the largest databases currently in existence, which are on the order of hundreds of petabytes.

...

Thus, for there to be a one in a billion chance of duplication, 103 trillion version 4 UUIDs must be generated.

If you want to use hex codes, you should add -e option to enable interpretation of backslash escapes by echo (but the result is the same as with echoCtrlRCtrlB). And as wallyk said, you probably want to add -n to prevent the output of a newline:

echo -en '\x12\x02' > /dev/ttyS0

Also make sure that /dev/ttyS0 is the port you want.

Note: in C# the term "function" is often replaced by the term "method". For the sake of this question there is no difference, so I'll just use the term "function".

The other answers have already given you a quick way to fix your problem (just make Add a static function), but I'd like to explain why.

C# has a fundamentally different design paradigm than C. That paradigm is called object-oriented programming (OOP). Explaining all the differences between OOP and functional programming is beyond the scope of this question, but here's the short version as it applies to you.

Writing your program in C, you would have created a function that adds two numbers, and that function would exist independently and be callable from anywhere. In C# most functions don't exist independently; instead, they exist in the context of an object. In your example code, only an instance (an object) of the class Program knows how to perform Add. Said another way, you have to create an instance of Program, and then ask Program to perform an Add for you.

The solutions that people gave you, using the static keyword, route around that design. Using the static keyword is kind of like saying, "Hey, this function I'm defining doesn't need any context/state, it can just be called." Since your Add function is very simple, this makes sense. As you start diving deeper into OOP, you're going to find that your functions get more complicated and rely on knowing their state/context.

My advice: Pick up an OOP book and get ready to switch your brain from functional programming to OOP programming. You're in for a ride.

You can use instance_of?

e.g

@some_var.instance_of?(Hash)

\d{1,3} will match numbers like 00 or 333 as well which wouldn't be a valid ID.

This is an excellent answer from smink, citing:

ValidIpAddressRegex = "^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$";

Adding Quotes

I started using this quick and dirty function in my .vimrc:

vnoremap q <esc>:call QuickWrap("'")<cr>
vnoremap Q <esc>:call QuickWrap('"')<cr>

function! QuickWrap(wrapper)
  let l:w = a:wrapper
  let l:inside_or_around = (&selection == 'exclusive') ? ('i') : ('a')
  normal `>
  execute "normal " . inside_or_around . escape(w, '\')
  normal `<
  execute "normal i" . escape(w, '\')
  normal `<
endfunction

So now, I visually select whatever I want (typically via viw - visually select inside word) in quotes and press Q for double quotes, or press q for single quotes.

Removing Quotes

vnoremap s <esc>:call StripWrap()<cr>

function! StripWrap()
  normal `>x`<x
endfunction

I use vim-textobj-quotes so that vim treats quotes as a text objects. This means I can do vaq (visually select around quotes. This finds the nearest quotes and visually selects them. (This is optional, you can just do something like f"vww). Then I press s to strip the quotes from the selection.

Changing Quotes

KISS. I remove quotes then add quotes. For example, to replace single quotes with double quotes, I would perform the steps: 1. remove single quotes: vaqs, 2. add new quotes: vwQ.

Kotlin

Based on Suragch's answer, here is an elegant way using View extension:

fun View.slideUp(duration: Int = 500) {
    visibility = View.VISIBLE
    val animate = TranslateAnimation(0f, 0f, this.height.toFloat(), 0f)
    animate.duration = duration.toLong()
    animate.fillAfter = true
    this.startAnimation(animate)
}

fun View.slideDown(duration: Int = 500) {
    visibility = View.VISIBLE
    val animate = TranslateAnimation(0f, 0f, 0f, this.height.toFloat())
    animate.duration = duration.toLong()
    animate.fillAfter = true
    this.startAnimation(animate)
}

And then wherever you want to use it, you just need myView.slideUp() or myView.slideDown()

Another way to restore the menu bar is to trigger the View: Toggle Menu Bar command in the command palette (F1).

ActiveCell.Offset(0, -1).Select
Selection.End(xlDown).Select
ActiveCell.Offset(0, 1).Select
Range(Selection, Selection.End(xlUp)).Select
Selection.FillDown

Here's an elegant solution for Angular 5.x+:

Component:

import {
  ChangeDetectionStrategy,
  ChangeDetectorRef,
  Component,
  ElementRef,
  EventEmitter,
  Input,
  OnInit,
  Output,
  Renderer2,
  ViewChild
} from '@angular/core';

@Component({
  selector: 'copy-to-clipboard',
  templateUrl: './copy-to-clipboard.component.html',
  styleUrls: ['./copy-to-clipboard.component.scss'],
  changeDetection: ChangeDetectionStrategy.OnPush
})

export class CopyToClipboardComponent implements OnInit {
  @ViewChild('input') input: ElementRef;
  @Input() size = 'md';
  @Input() theme = 'complement';
  @Input() content: string;
  @Output() copied: EventEmitter<string> = new EventEmitter<string>();
  @Output() error: EventEmitter<string> = new EventEmitter<string>();

  constructor(private renderer: Renderer2) {}

  ngOnInit() {}

  copyToClipboard() {

    const rootElement = this.renderer.selectRootElement(this.input.nativeElement);

    // iOS Safari blocks programmtic execCommand copying normally, without this hack.
    // https://stackoverflow.com/questions/34045777/copy-to-clipboard-using-javascript-in-ios
    if (navigator.userAgent.match(/ipad|ipod|iphone/i)) {

      this.renderer.setAttribute(this.input.nativeElement, 'contentEditable', 'true');

      const range = document.createRange();

      range.selectNodeContents(this.input.nativeElement);

      const sel = window.getSelection();

      sel.removeAllRanges();
      sel.addRange(range);

      rootElement.setSelectionRange(0, 999999);
    } else {
      rootElement.select();
    }

    try {
      document.execCommand('copy');
      this.copied.emit();
    } catch (err) {
      this.error.emit(err);
    }
  };
}

Template:

<button class="btn btn-{{size}} btn-{{theme}}" type="button" (click)="copyToClipboard()">
  <ng-content></ng-content>
</button>

<input #input class="hidden-input" [ngModel]="content">

Styles:

.hidden-input {
  position: fixed;
  top: 0;
  left: 0;
  width: 1px; 
  height: 1px;
  padding: 0;
  border: 0;
  box-shadow: none;
  outline: none;
  background: transparent;
}

for (int i = 0; i < a.length; i++) {
    for (int k = 0; k < a.length; k++) {
        if (a[i] != a[k]) {
            System.out.println(a[i] + " not the same with  " + a[k + 1] + "\n");
        }
    }
}

You can start from k=1 & keep "a.length-1" in outer for loop, in order to reduce two comparisions,but that doesnt make any significant difference.

I'll edit my previous answer based on further info supplied. You can clearely ping the remote computer as you can use terminal services.

I've a feeling that port 1433 is being blocked by a firewall, hence your trouble. See TCP Ports Needed for Communication to SQL Server Through a Firewall by Microsoft.

Try using this application to ping your servers ip address and port 1433.

tcping your.server.ip.address 1433

And see if you get a "Port is open" response from tcping.

Ok, next to try is to check SQL Server. RDP onto the SQL Server computer. Start SSMS. Connect to the database. In object explorer (usually docked on the left) right click on the server and click properties.

I'd prefer to normalize your table structure more, something like;

COMMENTS
-------
id (pk)
title
comment
userId


USERS
-----
id (pk)
name
email


COMMENT_VOTE
------------
commentId (pk)
userId (pk)
rating (float)

Now it's easier to maintain! And MySQL only accept one vote per user and comment.

Just run below command with admin access

npm install --global --production windows-build-tools

I am going to assume you are using the tnsnames.ora file to specify your available database services. If so connection errors usually come down to two things.

1. The application cannot find the TNS entry you specified in the connection string.

2. The TNS entry was found, but the IP or host is not correct in the tnsnames.ora file.

To expand on number 1 (which I think is your problem). When you tell Oracle to connect using something like:

sqlplus user/pass@service

The service is defined in the tnsnames.ora file. If I attempt to connect with a service that is not defined in my tnsnames.ora, I get the error you get:

[sodonnel@home ~]$ sqlplus sodonnel/sodonnel@nowhere

SQL*Plus: Release 11.2.0.1.0 Production on Mon Oct 31 21:42:15 2011

Copyright (c) 1982, 2009, Oracle.  All rights reserved.

ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified

So you need to check a few things:

1. Is there a tnsnames.ora file - I think yes because your console can connect
2. Is there an entry in the file for the service - I think also yes as the console connects
3. Can the application find the tnsnames.ora?

Your problem may well be number 3 - does the application run as a different user than when you run the console?

Oracle looks for the tnsnames.ora file in the directory defined in the TNS_ADMIN environment variable - If you are running as different users, then maybe the TNS_ADMIN environment variable is not set, and therefore it cannot find the file?

To find the number of days in a month, DateTime class provides a method "DaysInMonth(int year, int month)". This method returns the total number of days in a specified month.

public int TotalNumberOfDaysInMonth(int year, int month)
    {
        return DateTime.DaysInMonth(year, month);
    }

OR

int days = DateTime.DaysInMonth(2018,05);

Output :- 31

In tensorflow you create graphs and pass values to that graph. Graph does all the hardwork and generate the output based on the configuration that you have made in the graph. Now When you pass values to the graph then first you need to create a tensorflow session.

tf.Session()

Once session is initialized then you are supposed to use that session because all the variables and settings are now part of the session. So, there are two ways to pass external values to the graph so that graph accepts them. One is to call the .run() while you are using the session being executed.

Other way which is basically a shortcut to this is to use .eval(). I said shortcut because the full form of .eval() is

tf.get_default_session().run(values)

You can check that yourself. At the place of values.eval() run tf.get_default_session().run(values). You must get the same behavior.

what eval is doing is using the default session and then executing run().

A compiler and an interpreter do the same job: translating a programming language to another pgoramming language, usually closer to the hardware, often direct executable machine code.

Traditionally, "compiled" means that this translation happens all in one go, is done by a developer, and the resulting executable is distributed to users. Pure example: C++. Compilation usually takes pretty long and tries to do lots of expensive optmization so that the resulting executable runs faster. End users don't have the tools and knowledge to compile stuff themselves, and the executable often has to run on a variety of hardware, so you can't do many hardware-specific optimizations. During development, the separate compilation step means a longer feedback cycle.

Traditionally, "interpreted" means that the translation happens "on the fly", when the user wants to run the program. Pure example: vanilla PHP. A naive interpreter has to parse and translate every piece of code every time it runs, which makes it very slow. It can't do complex, costly optimizations because they'd take longer than the time saved in execution. But it can fully use the capabilities of the hardware it runs on. The lack of a separrate compilation step reduces feedback time during development.

But nowadays "compiled vs. interpreted" is not a black-or-white issue, there are shades in between. Naive, simple interpreters are pretty much extinct. Many languages use a two-step process where the high-level code is translated to a platform-independant bytecode (which is much faster to interpret). Then you have "just in time compilers" which compile code at most once per program run, sometimes cache results, and even intelligently decide to interpret code that's run rarely, and do powerful optimizations for code that runs a lot. During development, debuggers are capable of switching code inside a running program even for traditionally compiled languages.

If you need just to execute your VLC playback process and only give control back to your application process when it is done and nothing more complex, then i suppose you can use just:

system("The same thing you type into console");

Apache commons provides utility to convert the stack trace from throwable to string.

Usage:

ExceptionUtils.getStackTrace(e)

It allows browsers to determine if they can handle the scripting/style language before making a request for the script or stylesheet (or, in the case of embedded script/style, identify which language is being used).

This would be much more important if there had been more competition among languages in browser space, but VBScript never made it beyond IE and PerlScript never made it beyond an IE specific plugin while JSSS was pretty rubbish to begin with.

The draft of HTML5 makes the attribute optional.

I had the same issue.

First I downloaded the XML file to local desktop and I got Content is not allowed in prolog during the importing file to portal server. Even visually file was looking good to me but somehow it's was corrupted.

So I re-download the same file and tried the same and it worked.

Found this post: "Breaking changes" in angular 9. All modules must be imported separately. Also a fine module available there, thanks to @jeff-gilliland: https://stackoverflow.com/a/60111086/824622

Add this at the start of main

ApplicationContext context = new ClassPathXmlApplicationContext("path/to/applicationContext.xml");

JobLauncher launcher=(JobLauncher)context.getBean("launcher");
Job job=(Job)context.getBean("job");

//Get as many beans you want
//Now do the thing you were doing inside test method
StopWatch sw = new StopWatch();
sw.start();
launcher.run(job, jobParameters);
sw.stop();
//initialize the log same way inside main
logger.info(">>> TIME ELAPSED:" + sw.prettyPrint());

Use SQL Server Migration Assistant (SSMA)

In addition to MySQL it supports Oracle, Sybase and MS Access.

It appears to be quite smart and capable of handling even nontrivial transfers. It also got some command line interface (in addition to GUI) so theoretically it can be integrated into some batch load process.

This the current download link for MySQL version https://www.microsoft.com/en-us/download/details.aspx?id=54257

The current (June 2016) stable version 6.0.1 crashes with the current (5.3.6) MySQL ODBC driver while transferring data. Everything 64 bit. The 5.3 version with the 5.1.13 ODBC driver works fine.

As a general (see Stackblitz here: https://stackblitz.com/edit/angular-gh2rjx):

HTML

<select [(ngModel)]="selectedOption">
   <option *ngFor="let o of options">
      {{o.name}}
   </option>
</select>
<button (click)="print()">Click me</button>

<p>Selected option: {{ selectedOption }}</p>
<p>Button output: {{ printedOption }}</p>

Typescript

export class AppComponent {
  selectedOption: string;
  printedOption: string;

  options = [
    { name: "option1", value: 1 },
    { name: "option2", value: 2 }
  ]
  print() {
    this.printedOption = this.selectedOption;
  }
}

In your specific case you can use ngModel like this:

<form class="form-inline" (ngSubmit)="HelloCorp()">
     <div class="select">
         <select [(ngModel)]="corporationObj" class="form-control col-lg-8" #corporation required>
             <option *ngFor="let corporation of corporations"></option>    
         </select>
         <button type="submit" class="btn btn-primary manage">Submit</button>
     </div>
</form>

HelloCorp() {
  console.log("My input: ", corporationObj);
}

try this:

Use ´return false´ for to cut the flow of the event:

$('#login_form').submit(function() {
    var data = $("#login_form :input").serializeArray();
    alert('Handler for .submit() called.');
    return false;  // <- cancel event
});

Edit

corroborate if the form element with the 'length' of jQuery:

alert($('#login_form').length) // if is == 0, not found form
$('#login_form').submit(function() {
    var data = $("#login_form :input").serializeArray();
    alert('Handler for .submit() called.');
    return false;  // <- cancel event
});

OR:

it waits for the DOM is ready:

jQuery(function() {

    alert($('#login_form').length) // if is == 0, not found form
    $('#login_form').submit(function() {
        var data = $("#login_form :input").serializeArray();
        alert('Handler for .submit() called.');
        return false;  // <- cancel event
    });

});

Do you put your code inside the event "ready" the document or after the DOM is ready?

Try this:

nohup python -u <your file name>.py >> <your log file>.log &

You can run above command in screen and come out of screen.

Now you can tail logs of your python script by: tail -f <your log file>.log

To kill you script, you can use ps -aux and kill commands.

I came to this post because I had the same error.

In my case the database evolutions weren't been executed, so the table wasn't there at all.

My problem was that the folder structure for the evolution scripts was wrong.

from: https://www.playframework.com/documentation/2.0/Evolutions

Play tracks your database evolutions using several evolutions script. These scripts are written in plain old SQL and should be located in the conf/evolutions/{database name} directory of your application. If the evolutions apply to your default database, this path is conf/evolutions/default.

I had a folder called conf/evolutions.default created by eclipse. The issue disappeared after I corrected the folder structure to conf/evolutions/default

Although there are some good answers for this question. I would like to give another answer here with several examples of loop.

• O(n): Time Complexity of a loop is considered as O(n) if the loop variables is incremented / decremented by a constant amount. For example following functions have O(n) time complexity.

  // Here c is a positive integer constant   
  for (int i = 1; i <= n; i += c) {  
      // some O(1) expressions
  }
  
  for (int i = n; i > 0; i -= c) {
      // some O(1) expressions
  }
  

• O(n^c): Time complexity of nested loops is equal to the number of times the innermost statement is executed. For example the following sample loops have O(n^2) time complexity

  for (int i = 1; i <=n; i += c) {
     for (int j = 1; j <=n; j += c) {
        // some O(1) expressions
     }
  }
  
  for (int i = n; i > 0; i += c) {
     for (int j = i+1; j <=n; j += c) {
        // some O(1) expressions
  }
  

  For example Selection sort and Insertion Sort have O(n^2) time complexity.

• O(Logn) Time Complexity of a loop is considered as O(Logn) if the loop variables is divided / multiplied by a constant amount.

  for (int i = 1; i <=n; i *= c) {
     // some O(1) expressions
  }
  for (int i = n; i > 0; i /= c) {
     // some O(1) expressions
  }
  

  For example Binary Search has O(Logn) time complexity.

• O(LogLogn) Time Complexity of a loop is considered as O(LogLogn) if the loop variables is reduced / increased exponentially by a constant amount.

  // Here c is a constant greater than 1   
  for (int i = 2; i <=n; i = pow(i, c)) { 
     // some O(1) expressions
  }
  //Here fun is sqrt or cuberoot or any other constant root
  for (int i = n; i > 0; i = fun(i)) { 
     // some O(1) expressions
  }
  

One example of time complexity analysis

int fun(int n)
{    
    for (int i = 1; i <= n; i++)
    {
        for (int j = 1; j < n; j += i)
        {
            // Some O(1) task
        }
    }    
}

Analysis:

For i = 1, the inner loop is executed n times. For i = 2, the inner loop is executed approximately n/2 times. For i = 3, the inner loop is executed approximately n/3 times. For i = 4, the inner loop is executed approximately n/4 times. ……………………………………………………. For i = n, the inner loop is executed approximately n/n times.

So the total time complexity of the above algorithm is (n + n/2 + n/3 + … + n/n), Which becomes n * (1/1 + 1/2 + 1/3 + … + 1/n)

The important thing about series (1/1 + 1/2 + 1/3 + … + 1/n) is equal to O(Logn). So the time complexity of the above code is O(nLogn).

TRY THIS:

Cast your VARCHAR value to DATETIME and add -30 for subtraction. Also, In sql-server the format Fri, 14 Nov 2014 23:03:35 GMT was not converted to DATETIME. Try substring for it:

SELECT DATEADD(dd, -30, 
       CAST(SUBSTRING ('Fri, 14 Nov 2014 23:03:35 GMT', 6, 21) 
       AS DATETIME))

As several users have already said, you can't catch the exception. However, if you're struggling to find out where it's happening, you may want to configure visual studio to break when it's thrown.

To do that, you need to open Exception Settings from the 'Debug' menu. In older versions of Visual Studio, this is at 'Debug' - 'Exceptions'; in newer versions, it's at 'Debug' - 'Windows' - 'Exception Settings'.

Once you have the settings open, expand 'Common Language Runtime Exceptions', expand 'System', scroll down and check 'System.StackOverflowException'. Then you can look at the call stack and look for the repeating pattern of calls. That should give you an idea of where to look to fix the code that's causing the stack overflow.

Not sure I completely understand the question but:

$(":button.brown").click(function() {
  $(":button.brown.selected").removeClass("selected");
  $(this).addClass("selected");
});

seems to be along the lines of what you want.

I would certainly recommend using classes instead of directly setting CSS, which is problematic for several reasons (eg removing styles is non-trivial, removing classes is easy) but if you do want to go that way:

$("...").css("background", "brown");

But when you want to reverse that change, what do you set it to?

On laravel 5.6 it has a very simple solution:

User::where('username', $username)->first()->groupName;

It will return groupName as a string.

There are two ways to access properties of objects:

var obj = {a: 'foo', b: 'bar'};

obj.a //foo
obj['b'] //bar

Or, if you need to dynamically do it:

var key = 'b';
obj[key] //bar

If you don't already have it as an object, you'll need to convert it.

For a more complex example, let's assume you have an array of objects that represent users:

var users = [{name: 'Corbin', age: 20, favoriteFoods: ['ice cream', 'pizza']},
             {name: 'John', age: 25, favoriteFoods: ['ice cream', 'skittle']}];

To access the age property of the second user, you would use users[1].age. To access the second "favoriteFood" of the first user, you'd use users[0].favoriteFoods[2].

Another example: obj[2].key[3]["some key"]

That would access the 3rd element of an array named 2. Then, it would access 'key' in that array, go to the third element of that, and then access the property name some key.

As Amadan noted, it might be worth also discussing how to loop over different structures.

To loop over an array, you can use a simple for loop:

var arr = ['a', 'b', 'c'],
    i;
for (i = 0; i < arr.length; ++i) {
    console.log(arr[i]);
}

To loop over an object is a bit more complicated. In the case that you're absolutely positive that the object is a plain object, you can use a plain for (x in obj) { } loop, but it's a lot safer to add in a hasOwnProperty check. This is necessary in situations where you cannot verify that the object does not have inherited properties. (It also future proofs the code a bit.)

var user = {name: 'Corbin', age: 20, location: 'USA'},
    key;

for (key in user) {
    if (user.hasOwnProperty(key)) {
        console.log(key + " = " + user[key]);
    }
}    

(Note that I've assumed whatever JS implementation you're using has console.log. If not, you could use alert or some kind of DOM manipulation instead.)

Simple socket server app example

I've already posted a client example at: https://stackoverflow.com/a/35971718/895245 , so here goes a server example.

This example app runs a server that returns a ROT-1 cypher of the input.

You would then need to add an Exit button + some sleep delays, but this should get you started.

To play with it:

• install the app
• get your phone and PC on a LAN
• find your phone's IP with https://android.stackexchange.com/a/130468/126934
• run netcat $PHONE_IP 12345
• type some lines

Android sockets are the same as Java's, except we have to deal with some permission issues.

At the end, Node is about Javascript. JS has several way to accomplished something, is the same thing to get an "constructor", the important thing is to return a function.

This way actually you are creating a new function, as we created using JS on Web Browser environment for example.

Personally i prefer the prototype approach, as Sukima suggested on this post: Node.js - use of module.exports as a constructor

T-SQL doesn't support arrays that I'm aware of.

What's your table structure? You could probably design a query that does this instead:

select
month,
sum(sales)
from sales_table
group by month
order by month

If any of these characters, '>', '<', '|' or '*', are used, a single or double quotes must be used

conda install [-y] package">=version"
conda install [-y] package'>=low_version, <=high_version'
conda install [-y] "package>=low_version, <high_version"

conda install -y torchvision">=0.3.0"
conda install  openpyxl'>=2.4.10,<=2.6.0'
conda install "openpyxl>=2.4.10,<3.0.0"

where option -y, --yes Do not ask for confirmation.

Here is a summary:

Format         Sample Specification     Results
Exact          qtconsole==4.5.1         4.5.1
Fuzzy          qtconsole=4.5            4.5.0, 4.5.1, ..., etc.
>=, >, <, <=  "qtconsole>=4.5"          4.5.0 or higher
               qtconsole"<4.6"          less than 4.6.0

OR            "qtconsole=4.5.1|4.5.2"   4.5.1, 4.5.2
AND           "qtconsole>=4.3.1,<4.6"   4.3.1 or higher but less than 4.6.0

Here is creating a ComboBox adding a listener for item selection change:

JComboBox comboBox = new JComboBox();

comboBox.setBounds(84, 45, 150, 20);
contentPane.add(comboBox);

JComboBox comboBox_1 = new JComboBox();
comboBox_1.setBounds(84, 97, 150, 20);
contentPane.add(comboBox_1);
comboBox.addItemListener(new ItemListener() {
    public void itemStateChanged(ItemEvent arg0) {
        //Do Something
    }
});

When you include a string literal in a query, you can enclose the string in either single or double quotes; Access' database engine will accept either. So double quotes will avoid the problem with a string which contains a single quote.

SELECT * FROM tblStudents WHERE [name] Like "Daniel O'Neal";

If you want to keep the single quotes around your string, you can double up the single quote within it, as mentioned in other answers.

SELECT * FROM tblStudents WHERE [name] Like 'Daniel O''Neal';

Notice the square brackets surrounding name. I used the brackets to lessen the chance of confusing the database engine because name is a reserved word.

It's not clear why you're using the Like comparison in your query. Based on what you've shown, this should work instead.

SELECT * FROM tblStudents WHERE [name] = "Daniel O'Neal";

There is another trick :

/* Padding on the sides of the table */
table th:first-child, .list td:first-child { padding-left: 28px; }
table th:last-child, .list td:last-child { padding-right: 28px; }

(Just saw it at my current job)

It's better to have a proper JSON format instead of directly using the one converted from XML.

[
  {
    "number": "2013-W45",
    "days": [
      {
        "dow": "1",
        "templateDay": "Monday",
        "jobs": [
          {
            "name": "Wakeup",
            "jobs": [
              {
                "name": "prepare breakfast",

              }
            ]
          },
          {
            "name": "work 9-5",

          }
        ]
      },
      {
        "dow": "2",
        "templateDay": "Tuesday",
        "jobs": [
          {
            "name": "Wakeup",
            "jobs": [
              {
                "name": "prepare breakfast",

              }
            ]
          }
        ]
      }
    ]
  }
]

This will make things much easier and easy to loop through.

Now you can write the loop as -

<div ng-repeat="week in myData">
   <div ng-repeat="day in week.days">
      {{day.dow}} - {{day.templateDay}}
      <b>Jobs:</b><br/> 
       <ul>
         <li ng-repeat="job in day.jobs"> 
           {{job.name}} 
         </li>
       </ul>
   </div>
</div>

Update image field to add full URL, ignoring null fields:

UPDATE test SET image = CONCAT('https://my-site.com/images/',image) WHERE image IS NOT NULL;

If you don't want to make it final, you can always just make it a global variable.

The initial problem is that the the configuration specifies a property suffix=".jsp" so the ViewResolver implementing class will add .jsp to the end of the view name being returned from your method.

However since you commented out the InternalResourceViewResolver then, depending on the rest of your application configuration, there might not be any other ViewResolver registered. You might find that nothing is working now.

Since .html files are static and do not require processing by a servlet then it is more efficient, and simpler, to use an <mvc:resources/> mapping. This requires Spring 3.0.4+.

For example:

<mvc:resources mapping="/static/**" location="/static/" />

which would pass through all requests starting with /static/ to the webapp/static/ directory.

So by putting index.html in webapp/static/ and using return "static/index.html"; from your method, Spring should find the view.

As far as the http verb is concerned the WebRequest might be easier. You could go for something like:

    WebRequest r = WebRequest.Create("http://some.url");
    r.Method = "POST";
    using (var s = r.GetResponse().GetResponseStream())
    {
        using (var reader = new StreamReader(r, FileMode.Open))
        {
            var content = reader.ReadToEnd();
        }
    }

Obviously this lacks exception handling and writing the request body (for which you can use r.GetRequestStream() and write it like a regular stream, but I hope it may be of some help.

Do it like this

if (typeof $(this).attr("checked") == "undefined" )

// To check if checkbox is checked
if( $(this).attr("checked")=="checked")

The fastest way that I came up is using EnumerateFiles with SearchOption.AllDirectories. This method also allows updating the UI while going through the files and counting the size. Long path names don't cause any problems since FileInfo or DirectoryInfo are not tried to be created for the long path name. While enumerating files even though the filename is long the FileInfo returned by the EnumerateFiles don't cause problems as long as the starting directory name is not too long. There is still a problem with UnauthorizedAccess.

    private void DirectoryCountEnumTest(string sourceDirName)
    {
        // Get the subdirectories for the specified directory.
        long dataSize = 0;
        long fileCount = 0;
        string prevText = richTextBox1.Text;

        if (Directory.Exists(sourceDirName))
        {
            DirectoryInfo dir = new DirectoryInfo(sourceDirName);
            foreach (FileInfo file in dir.EnumerateFiles("*", SearchOption.AllDirectories))
            {
                fileCount++;
                try
                {
                    dataSize += file.Length;
                    richTextBox1.Text = prevText + ("\nCounting size: " + dataSize.ToString());
                }
                catch (Exception e)
                {
                    richTextBox1.AppendText("\n" + e.Message);
                }
            }
            richTextBox1.AppendText("\n files:" + fileCount.ToString());
        }
    }

The simple way to get (one) element from array by id:

The find() method returns the value of the first element in the array that satisfies the provided testing function. Otherwise undefined is returned.

function isBigEnough(element) {
    return element >= 15;
}

var integers = [12, 5, 8, 130, 160, 44];
integers.find(isBigEnough); // 130  only one element - first

you don't need to use filter() and catch first element xx.filter()[0] like in comments above

The same for objects in array

var foo = {
"results" : [{
    "id" : 1,
    "name" : "Test"
}, {
    "id" : 2,
    "name" : "Beispiel"
}, {
    "id" : 3,
    "name" : "Sample"
}
]};

var secondElement = foo.results.find(function(item){
    return item.id == 2;
});

var json = JSON.stringify(secondElement);
console.log(json);

Of course if you have multiple id then use filter() method to get all objects. Cheers

Using str(e) or repr(e) to represent the exception, you won't get the actual stack trace, so it is not helpful to find where the exception is.

After reading other answers and the logging package doc, the following two ways works great to print the actual stack trace for easier debugging:

use logger.debug() with parameter exc_info

try:
    # my code
except SomeError as e:
    logger.debug(e, exc_info=True)

use logger.exception()

or we can directly use logger.exception() to print the exception.

try:
    # my code
except SomeError as e:
    logger.exception(e)

For someone who needs an explanation and an example of how to use a regxp in Eclipse. Here is my example illustrating the problem.

I want to rename

/download.mp4^lecture_id=271

to

/271.mp4

And there can be multiple of these.

Here is how it should be done.

Then hit find/replace button

The first time you run the page, the query_age index doesn't exist because it hasn't been sent over from the form.

When you submit the form it will then exist, and it won't complain about it.

#so change
$_GET['query_age'];
#to:
(!empty($_GET['query_age']) ? $_GET['query_age'] : null);

The Go trough this link state that the first argument of Output() is the file path, second is the saving mode - you need to set it to 'F'.

 $upload_dir = public_path(); 
             $filename = $upload_dir.'/testing7.pdf'; 
              $mpdf = new \Mpdf\Mpdf();
              //$test = $mpdf->Image($pro_image, 0, 0, 50, 50);

              $html ='<h1> Project Heading </h1>';
              $mail = ' <p> Project Heading </p> ';
              
              $mpdf->autoScriptToLang = true;
              $mpdf->autoLangToFont = true;
              $mpdf->WriteHTML($mail);

              $mpdf->Output($filename,'F'); 
              $mpdf->debug = true;

Example :

 $mpdf->Output($filename,'F');

Example #2

$mpdf = new \Mpdf\Mpdf();
$mpdf->WriteHTML('Hello World');

// Saves file on the server as 'filename.pdf'
$mpdf->Output('filename.pdf', \Mpdf\Output\Destination::FILE);

I don't know if it helps, but using jQuery, to hide an email address, I did :

    $(function() {
        // planque l'adresse mail
        var mailSplitted 
            = ['mai', 'to:mye', 'mail@', 'addre', 'ss.fr'];

        var link = mailSplitted.join('');
        link = '<a href="' + link + '"</a>';
        $('mytag').wrap(link);
    });

I hope it helps.

LG Optimus Zone 2 pp415 d\n connect in mtp, but does work in internet connection mode. Lost lots of time messing with it. There's no doc for this, but I'd suggest trying all 4 of the connection options. Only 1 that works for me is Internet Connection->Ethernet, then win 8 auto-detects a driver and installs it. In MTP mode despite all drivers being registered with device manager, adb doesn't pick it up.

Can we make an Android NFC as the tag which an NFC reader will get data from?

The Nexus S supports peer-to-peer mode, which as its name implies, causes one phone to act as a tag which another phone can read. There was a really good Google I/O session on NFC this year. I would recommended watching it if you're at all interested in NFC.

This is an old issue, but I ran into it while searching. Turns out that I was missing the actual filename component in the save path for SaveAs...

string uploadPath = Server.MapPath("~/uploads");
file.SaveAs(uploadPath); // BAD
file.SaveAs(Path.Combine(uploadPath, file.FileName)); // GOOD

I suggest, never delete data. Don't say if the tables is longer than 1000 truncate the end of the table. There needs to be real business logic in your plan like how long has this user been inactive. For example, if it is longer than 1 year then put them in a different table. You would have this happen weekly or monthly in a maintenance script in the middle of a slow time.

When you run into to many rows in your table then you should start sharding the tables or partitioning and put old data in old tables by year such as users_2011_jan, users_2011_feb or use numbers for the month. Then change your programming to work with this model. Maybe make a new table with less information to summarize the data in less columns and then only refer to the bigger partitioned tables when you need more information such as when the user is viewing their profile. All of this should be considered very carefully so in the future it isn't too expensive to re-factor. You could also put only the users which comes to your site all the time in one table and the users that never come in an archived set of tables.

Answer (Basic is advance!):

Error: 10060 Adding a timeout parameter to request solved the issue for me.

Example 1

import urllib
import urllib2
g = "http://www.google.com/"
read = urllib2.urlopen(g, timeout=20)

Example 2

A similar error also occurred while I was making a GET request. Again, passing a timeout parameter solved the 10060 Error.

response = requests.get(param_url, timeout=20)

You could either access the element’s value by its name:

document.getElementsByName("textbox1"); // returns a list of elements with name="textbox1"
document.getElementsByName("textbox1")[0] // returns the first element in DOM with name="textbox1"

So:

<input name="buttonExecute" onclick="execute(document.getElementsByName('textbox1')[0].value)" type="button" value="Execute" />

Or you assign an ID to the element that then identifies it and you can access it with getElementById:

<input name="textbox1" id="textbox1" type="text" />
<input name="buttonExecute" onclick="execute(document.getElementById('textbox1').value)" type="button" value="Execute" />

By default, Log4j logs to standard output and that means you should be able to see log messages on your Eclipse's console view. To log to a file you need to use a FileAppender explicitly by defining it in a log4j.properties file in your classpath.

Create the following log4j.properties file in your classpath. This allows you to log your message to both a file as well as your console.

log4j.rootLogger=debug, stdout, file

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=example.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%p %t %c - %m%n

Note: The above creates an example.log in your current working directory (i.e. Eclipse's project directory) so that the same log4j.properties could work with different projects without overwriting each other's logs.

For me, the gem lock file was specifying an older version of cocoapods than the one I had installed. I had to re-branch and run bundle exec pod install instead of pod install

I'm currently running Android Studio on Windows 8.1 machine with 6 gigs of RAM.

I found that disabling VCS in android studio and using an external program to handle VCS helped a lot. You can disable VCS by going to File->Settings->Plugins and disable the following:

• CVS Integration
• Git Integration
• GitHub
• Google Cloud Testing
• Google Cloud Tools Core
• Google Cloud Tools for Android Studio
• hg4idea
• Subversion Integration
• Mercurial Integration
• TestNG-J

To reset the default settings I'm not sure, but if you're just trying to get a menu bar back then try right clicking on the anywhere on the toolbar area and clicking the toolbar you need.

EDIT:
Figured out how to reset the settings Click on the tools button on the top, click "Import and Export Settings" and then click "Reset All Settings". Then go through the wizard from there.

Forcing the buttons stay in the same line will make them go beyond the fixed width of the div they are in. If you are okay with that then you can make another div inside the div you already have. The new div in turn will hold the buttons and have the fixed width of however much space the two buttons need to stay in one line.

Here is an example:

<div id="parentDiv" style="width: [less-than-what-buttons-need]px;">
    <div id="holdsButtons" style="width: [>=-than-buttons-need]px;">
       <button id="button1">1</button>
       <button id="button2">2</button>
    </div>
</div>

You may want to consider overflow property for the chunk of the content outside of the parentDiv border.

Good luck!

data will return you a string representation of a list, but it is actually still a string. Just check the type of data with type(data). That means if you try using indexing on this string representation of a list as such data['fruits'][0], it will return you "[" as it is the first character of data['fruits']

You can do json.loads(data['fruits']) to convert it back to a Python list so that you can interact with regular list indexing. There are 2 other ways you can convert it back to a Python list suggested here

Step 1:

D:\projects\Phonegap\Example> cordova plugin rm org.apache.cordova.console --save

add the --save so that it removes the plugin from the config.xml file.

Step 2:

To generate a release build for Android, we first need to make a small change to the AndroidManifest.xml file found in platforms/android. Edit the file and change the line:

<application android:debuggable="true" android:hardwareAccelerated="true" android:icon="@drawable/icon" android:label="@string/app_name">

and change android:debuggable to false:

<application android:debuggable="false" android:hardwareAccelerated="true" android:icon="@drawable/icon" android:label="@string/app_name">

As of cordova 6.2.0 remove the android:debuggable tag completely. Here is the explanation from cordova:

Explanation for issues of type "HardcodedDebugMode": It's best to leave out the android:debuggable attribute from the manifest. If you do, then the tools will automatically insert android:debuggable=true when building an APK to debug on an emulator or device. And when you perform a release build, such as Exporting APK, it will automatically set it to false.

If on the other hand you specify a specific value in the manifest file, then the tools will always use it. This can lead to accidentally publishing your app with debug information.

Step 3:

Now we can tell cordova to generate our release build:

D:\projects\Phonegap\Example> cordova build --release android

Then, we can find our unsigned APK file in platforms/android/ant-build. In our example, the file was platforms/android/ant-build/Example-release-unsigned.apk

Step 4:

Note : We have our keystore keystoreNAME-mobileapps.keystore in this Git Repo, if you want to create another, please proceed with the following steps.

Key Generation:

Syntax:

keytool -genkey -v -keystore <keystoreName>.keystore -alias <Keystore AliasName> -keyalg <Key algorithm> -keysize <Key size> -validity <Key Validity in Days>

Egs:

keytool -genkey -v -keystore NAME-mobileapps.keystore -alias NAMEmobileapps -keyalg RSA -keysize 2048 -validity 10000


keystore password? : xxxxxxx
What is your first and last name? :  xxxxxx
What is the name of your organizational unit? :  xxxxxxxx
What is the name of your organization? :  xxxxxxxxx
What is the name of your City or Locality? :  xxxxxxx
What is the name of your State or Province? :  xxxxx
What is the two-letter country code for this unit? :  xxx

Then the Key store has been generated with name as NAME-mobileapps.keystore

Step 5:

Place the generated keystore in

old version cordova

D:\projects\Phonegap\Example\platforms\android\ant-build

New version cordova

D:\projects\Phonegap\Example\platforms\android\build\outputs\apk

To sign the unsigned APK, run the jarsigner tool which is also included in the JDK:

Syntax:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore <keystorename> <Unsigned APK file> <Keystore Alias name>

Egs:

D:\projects\Phonegap\Example\platforms\android\ant-build> jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore NAME-mobileapps.keystore Example-release-unsigned.apk xxxxxmobileapps

OR

D:\projects\Phonegap\Example\platforms\android\build\outputs\apk> jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore NAME-mobileapps.keystore Example-release-unsigned.apk xxxxxmobileapps

Enter KeyPhrase as 'xxxxxxxx'

This signs the apk in place.

Step 6:

Finally, we need to run the zip align tool to optimize the APK:

D:\projects\Phonegap\Example\platforms\android\ant-build> zipalign -v 4 Example-release-unsigned.apk Example.apk 

OR

D:\projects\Phonegap\Example\platforms\android\ant-build> C:\Phonegap\adt-bundle-windows-x86_64-20140624\sdk\build-tools\android-4.4W\zipalign -v 4 Example-release-unsigned.apk Example.apk

OR

D:\projects\Phonegap\Example\platforms\android\build\outputs\apk> C:\Phonegap\adt-bundle-windows-x86_64-20140624\sdk\build-tools\android-4.4W\zipalign -v 4 Example-release-unsigned.apk Example.apk

Now we have our final release binary called example.apk and we can release this on the Google Play Store.

If you already have a number of dates already highlighted and want to determine which date was last clicked then you'll need the following:

$('#startdate').data('datepicker').viewDate

viewDate returns a JavaScript date object so you'll need to handle it accordingly.

SQL Server 2000, 2005, 2008, 2012, 2014, 2016, 2017 or 2019:

SELECT * FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='BASE TABLE'

To show only tables from a particular database

SELECT TABLE_NAME 
FROM [<DATABASE_NAME>].INFORMATION_SCHEMA.TABLES 
WHERE TABLE_TYPE = 'BASE TABLE'

Or,

SELECT TABLE_NAME 
FROM INFORMATION_SCHEMA.TABLES 
WHERE TABLE_TYPE = 'BASE TABLE' 
    AND TABLE_CATALOG='dbName' --(for MySql, use: TABLE_SCHEMA='dbName' )

PS: For SQL Server 2000:

SELECT * FROM sysobjects WHERE xtype='U' 

In Java, according to the JSSE Reference Guide, there is no default for the keystore, the default for the truststore is "jssecacerts, if it exists. Otherwise, cacerts".

A few applications use ~/.keystore as a default keystore, but this is not without problems (mainly because you might not want all the application run by the user to use that trust store).

I'd suggest using application-specific values that you bundle with your application instead, it would tend to be more applicable in general.

How do Python's any and all functions work?

any and all take iterables and return True if any and all (respectively) of the elements are True.

>>> any([0, 0.0, False, (), '0']), all([1, 0.0001, True, (False,)])
(True, True)            #   ^^^-- truthy non-empty string
>>> any([0, 0.0, False, (), '']), all([1, 0.0001, True, (False,), {}])
(False, False)                                                #   ^^-- falsey

If the iterables are empty, any returns False, and all returns True.

>>> any([]), all([])
(False, True)

I was demonstrating all and any for students in class today. They were mostly confused about the return values for empty iterables. Explaining it this way caused a lot of lightbulbs to turn on.

Shortcutting behavior

They, any and all, both look for a condition that allows them to stop evaluating. The first examples I gave required them to evaluate the boolean for each element in the entire list.

(Note that list literal is not itself lazily evaluated - you could get that with an Iterator - but this is just for illustrative purposes.)

Here's a Python implementation of any and all:

def any(iterable):
    for i in iterable:
        if i:
            return True
    return False # for an empty iterable, any returns False!

def all(iterable):
    for i in iterable:
        if not i:
            return False
    return True  # for an empty iterable, all returns True!

Of course, the real implementations are written in C and are much more performant, but you could substitute the above and get the same results for the code in this (or any other) answer.

all

all checks for elements to be False (so it can return False), then it returns True if none of them were False.

>>> all([1, 2, 3, 4])                 # has to test to the end!
True
>>> all([0, 1, 2, 3, 4])              # 0 is False in a boolean context!
False  # ^--stops here!
>>> all([])
True   # gets to end, so True!

any

The way any works is that it checks for elements to be True (so it can return True), then it returnsFalseif none of them wereTrue`.

>>> any([0, 0.0, '', (), [], {}])     # has to test to the end!
False
>>> any([1, 0, 0.0, '', (), [], {}])  # 1 is True in a boolean context!
True   # ^--stops here!
>>> any([])
False   # gets to end, so False!

I think if you keep in mind the short-cutting behavior, you will intuitively understand how they work without having to reference a Truth Table.

Evidence of all and any shortcutting:

First, create a noisy_iterator:

def noisy_iterator(iterable):
    for i in iterable:
        print('yielding ' + repr(i))
        yield i

and now let's just iterate over the lists noisily, using our examples:

>>> all(noisy_iterator([1, 2, 3, 4]))
yielding 1
yielding 2
yielding 3
yielding 4
True
>>> all(noisy_iterator([0, 1, 2, 3, 4]))
yielding 0
False

We can see all stops on the first False boolean check.

And any stops on the first True boolean check:

>>> any(noisy_iterator([0, 0.0, '', (), [], {}]))
yielding 0
yielding 0.0
yielding ''
yielding ()
yielding []
yielding {}
False
>>> any(noisy_iterator([1, 0, 0.0, '', (), [], {}]))
yielding 1
True

The source

Let's look at the source to confirm the above.

Here's the source for any:

static PyObject *
builtin_any(PyObject *module, PyObject *iterable)
{
    PyObject *it, *item;
    PyObject *(*iternext)(PyObject *);
    int cmp;

    it = PyObject_GetIter(iterable);
    if (it == NULL)
        return NULL;
    iternext = *Py_TYPE(it)->tp_iternext;

    for (;;) {
        item = iternext(it);
        if (item == NULL)
            break;
        cmp = PyObject_IsTrue(item);
        Py_DECREF(item);
        if (cmp < 0) {
            Py_DECREF(it);
            return NULL;
        }
        if (cmp > 0) {
            Py_DECREF(it);
            Py_RETURN_TRUE;
        }
    }
    Py_DECREF(it);
    if (PyErr_Occurred()) {
        if (PyErr_ExceptionMatches(PyExc_StopIteration))
            PyErr_Clear();
        else
            return NULL;
    }
    Py_RETURN_FALSE;
}

And here's the source for all:

static PyObject *
builtin_all(PyObject *module, PyObject *iterable)
{
    PyObject *it, *item;
    PyObject *(*iternext)(PyObject *);
    int cmp;

    it = PyObject_GetIter(iterable);
    if (it == NULL)
        return NULL;
    iternext = *Py_TYPE(it)->tp_iternext;

    for (;;) {
        item = iternext(it);
        if (item == NULL)
            break;
        cmp = PyObject_IsTrue(item);
        Py_DECREF(item);
        if (cmp < 0) {
            Py_DECREF(it);
            return NULL;
        }
        if (cmp == 0) {
            Py_DECREF(it);
            Py_RETURN_FALSE;
        }
    }
    Py_DECREF(it);
    if (PyErr_Occurred()) {
        if (PyErr_ExceptionMatches(PyExc_StopIteration))
            PyErr_Clear();
        else
            return NULL;
    }
    Py_RETURN_TRUE;
}

You may also use PSCredential.GetNetworkCredential() :

$SecurePassword = Get-Content C:\Users\tmarsh\Documents\securePassword.txt | ConvertTo-SecureString
$UnsecurePassword = (New-Object PSCredential "user",$SecurePassword).GetNetworkCredential().Password

Delete the "target" folder under the offending module. Then Build | Rebuild Project. Also make sure your clear the web browsers cache.

You could use $.ajax to avoid the natural behaviour of <form method="POST">. You could, for example, add an event to the submission button and treat the POST request as AJAX.

As somebody figures out that the OP wants to convert custom List to org.json.JSONArray not the com.google.gson.JsonArray,the CORRECT answer should be like this:

Gson gson = new Gson();

String listString = gson.toJson(
                    targetList,
           new TypeToken<ArrayList<targetListItem>>() {}.getType());

 JSONArray jsonArray =  new JSONArray(listString);

I tried a lot of things as mentioned in the above answers. The SQLmapper was very confusing as to where to put it. Non managed POJOs only were a problem. I was trying various ways and one easy way I got it worked was as usual. I am using hibernate-jpa-2.1.

List<TestInfo> testInfoList = factory.createNativeQuery(QueryConstants.RUNNING_TEST_INFO_QUERY)
                    .getResultList();

The only thing to take care was that POJO has same member variable names as that of the query ( all in lowercase). And apparently I didn't even need to tell the target class along with query as we do with TypedQueries in JPQL.

TestInfo.class

@Setter
@Getter
@NoArgsConstructor
@ToString
public class TestInfo {

    private String emailid;
    private Long testcount;

    public TestInfo(String emailId, Long testCount) {
        super();
        this.emailid = emailId;
        this.testcount = testCount;
    }

}

This has nothing to do with structs - arrays in C are not assignable:

char a[20];
a = "foo";   // error

you need to use strcpy:

strcpy( a, "foo" );

or in your code:

strcpy( sara.first, "Sara" );

I found one way to supply credentials for a https connection on the command line. You just need to specify the complete URL to git pull and include the credentials there:

git pull https://username:[email protected]/my/repository

You do not need to have the repository cloned with the credentials before, this means your credentials don't end up in .git/config. (But make sure your shell doesn't betray you and stores the command line in a history file.)

Keep in mind that the copy constructor limits the class type to that of the copy constructor. Consider the example:

// Need to clone person, which is type Person
Person clone = new Person(person);

This doesn't work if person could be a subclass of Person (or if Person is an interface). This is the whole point of clone, is that it can can clone the proper type dynamically at runtime (assuming clone is properly implemented).

Person clone = (Person)person.clone();

or

Person clone = (Person)SomeCloneUtil.clone(person); // See Bozho's answer

Now person can be any type of Person assuming that clone is properly implemented.

I had the same problem running Ubuntu 18.04. I tried multiple solutions but my device (OnePlus 5T) was always unauthorized.

Solution

1. Configure udev rules on Ubuntu. To do this, just follow the official documentation: https://developer.android.com/studio/run/device

   The idVendor of my device (OnePlus) is not listed. To get it, just connect your device and use lsusb:

   Bus 003 Device 008: ID 2a70:4ee7

   In this example, 2a70 is the idVendor.

2. Remove existing adb keys on Ubuntu:

   rm -v ~/.android/adbkey* ~/.android/adbkey ~/.android/adbkey.pub

3. 'Revoke USB debugging authorizations' on your device configuration (developer options).

4. Finally, restart the adb server to create a new key:

   sudo adb kill-server sudo adb devices

After that, I got the authorization prompt on my device and I authorized it.

you can always make a bash alias to setup*.exe files in $home/.bashrc

cygwin 32bit

alias cyg-get="/cygdrive/c/cygwin/setup-x86.exe -q -P"

cygwin 64bit

alias cyg-get="/cygdrive/c/cygwin64/setup-x86_64.exe -q -P"

now you can install packages with

cyg-get <package>

In React, when you want to pass an interpreted expression, you have to open a pair of curly braces. Try:

render () {
  return (
    <button className={`pill ${ this.props.styleName }`}>
      {this.props.children}
    </button>
  );
}

Using the classnames npm package

import classnames from 'classnames';

render() {
  return (
    <button className={classnames('pill', this.props.styleName)}>
      {this.props.children}
    </button>
  );
}

Your first example is perfectly fine. Even the official Python documentation recommends this style known as EAFP.

Personally, I prefer to avoid nesting when it's not necessary:

def __getattribute__(self, item):
    try:
        return object.__getattribute__(item)
    except AttributeError:
        pass  # Fallback to dict
    try:
        return self.dict[item]
    except KeyError:
        raise AttributeError("The object doesn't have such attribute") from None

PS. has_key() has been deprecated for a long time in Python 2. Use item in self.dict instead.

basename($_SERVER['REQUEST_URI']) returns everything after and including the '?',

In my code sometimes I need only sections, so separate it out so I can get the value of what I need on the fly. Not sure on the performance speed compared to other methods, but it's really useful for me.

$urlprotocol = 'http'; if ($_SERVER["HTTPS"] == "on") {$urlprotocol .= "s";} $urlprotocol .= "://";
$urldomain = $_SERVER["SERVER_NAME"];
$urluri = $_SERVER['REQUEST_URI'];
$urlvars = basename($urluri);
$urlpath = str_replace($urlvars,"",$urluri);

$urlfull = $urlprotocol . $urldomain . $urlpath . $urlvars;

Another advantage of using the '[[' operator is that it works both with data.frame and data.table. So if the function has to be made running for both data.frame and data.table, and you want to extract a column from it as a vector then

data[["column_name"]] 

is best.

SELECT COUNT(*), table1.category_id, table2.category_name 
FROM table1 
INNER JOIN table2 ON table1.category_id=table2.category_id 
WHERE table1.colour <> 'red'
GROUP BY table1.category_id, table2.category_name 

Make sure Qt5Core.dll is in the same directory with your application executable.

I had a similar issue in Qt5 with a console application: if I start the application from Qt Creator, the output text is visible, if I open cmd.exe and start the same application there, no output is visible. Very strange!

I solved it by copying Qt5Core.dll to the directory with the application executable.

Here is my tiny console application:

#include <QCoreApplication>
#include <QDebug>

int main(int argc, char *argv[])
{
    int x=343;
    QString str("Hello World");
    qDebug()<< str << x<<"lalalaa";

    QTextStream out(stdout);
    out << "aldfjals alsdfajs...";
}

One way, as suggested in this post, is to mention version in pip as:

pip install -Iv MySQL_python==1.2.2

i.e. Use == and mention the version number to install only that version. -I, --ignore-installed ignores already installed packages.

I came across this question while Googling for "git remove folder from tracking". The OP's question lead me to the answer. I am summarizing it here for future generations.

Question

How do I remove a folder from my git repository without deleting it from my local machine (i.e., development environment)?

Answer

Step 1. Add the folder path to your repo's root .gitignore file.

path_to_your_folder/

Step 2. Remove the folder from your local git tracking, but keep it on your disk.

git rm -r --cached path_to_your_folder/

Step 3. Push your changes to your git repo.

The folder will be considered "deleted" from Git's point of view (i.e. they are in past history, but not in the latest commit, and people pulling from this repo will get the files removed from their trees), but stay on your working directory because you've used --cached.

But,if you want to store a bunch of them you could bit-shift them and store them all as one int, a little like unix file permissions/modes.

For mode 755 for instance, each digit refers to a different class of users: owner, group, public. Within each digit 4 is read, 2 is write, 1 is execute so 7 is all of them like binary 111. 5 is read and execute so 101. Make up your own encoding scheme.

I'm just writing something for storing TV schedule data from Schedules Direct and I have the binary or yes/no fields: stereo, hdtv, new, ei, close captioned, dolby, sap in Spanish, season premiere. So 7 bits, or an integer with a maximum of 127. One character really.

A C example from what I'm working on now. has() is a function that returns 1 if the 2nd string is in the first one. inp is the input string to this function. misc is an unsigned char initialized to 0.

if (has(inp,"sap='Spanish'") > 0)
  misc += 1;
if (has(inp,"stereo='true'") > 0)
  misc +=2;
if (has(inp,"ei='true'") > 0)
  misc +=4;
if (has(inp,"closeCaptioned='true'") > 0)
  misc += 8;
if (has(inp,"dolby=") > 0)
  misc += 16;
if (has(inp,"new='true'") > 0)
  misc += 32;
if (has(inp,"premier_finale='") > 0)
  misc += 64;
if (has(inp,"hdtv='true'") > 0)
  misc += 128;

So I'm storing 7 booleans in one integer with room for more.
