When I ran taskkill to stop the javaw.exe process it would say it had terminated but remained running. The jqs process (java qucikstart) needs to be stopped also. Running this batch file took care of the issue.

taskkill /f /im jqs.exe
taskkill /f /im javaw.exe
taskkill /f /im java.exe

I have been investigating these ideas and here is my five cents worth. It avoids calling BoundaryNorm as well as specifying norm as an argument to scatter and colorbar. However I have found no way of eliminating the rather long-winded call to matplotlib.colors.LinearSegmentedColormap.from_list.

Some background is that matplotlib provides so-called qualitative colormaps, intended to use with discrete data. Set1, e.g., has 9 easily distinguishable colors, and tab20 could be used for 20 colors. With these maps it could be natural to use their first n colors to color scatter plots with n categories, as the following example does. The example also produces a colorbar with n discrete colors approprately labelled.

import matplotlib, numpy as np, matplotlib.pyplot as plt
n = 5
from_list = matplotlib.colors.LinearSegmentedColormap.from_list
cm = from_list(None, plt.cm.Set1(range(0,n)), n)
x = np.arange(99)
y = x % 11
z = x % n
plt.scatter(x, y, c=z, cmap=cm)
plt.clim(-0.5, n-0.5)
cb = plt.colorbar(ticks=range(0,n), label='Group')
cb.ax.tick_params(length=0)

which produces the image below. The n in the call to Set1 specifies the first n colors of that colormap, and the last n in the call to from_list specifies to construct a map with n colors (the default being 256). In order to set cm as the default colormap with plt.set_cmap, I found it to be necessary to give it a name and register it, viz:

cm = from_list('Set15', plt.cm.Set1(range(0,n)), n)
plt.cm.register_cmap(None, cm)
plt.set_cmap(cm)
...
plt.scatter(x, y, c=z)

The problem is that data:image/png;base64, is included in the encoded contents. This will result in invalid image data when the base64 function decodes it. Remove that data in the function before decoding the string, like so.

function base64_to_jpeg($base64_string, $output_file) {
    // open the output file for writing
    $ifp = fopen( $output_file, 'wb' ); 

    // split the string on commas
    // $data[ 0 ] == "data:image/png;base64"
    // $data[ 1 ] == <actual base64 string>
    $data = explode( ',', $base64_string );

    // we could add validation here with ensuring count( $data ) > 1
    fwrite( $ifp, base64_decode( $data[ 1 ] ) );

    // clean up the file resource
    fclose( $ifp ); 

    return $output_file; 
}

In a shameless attempt to steal some votes, SecurityProtocol is an Enum with the [Flags] attribute. So you can do this:

[Net.ServicePointManager]::SecurityProtocol = 
  [Net.SecurityProtocolType]::Tls12 -bor `
  [Net.SecurityProtocolType]::Tls11 -bor `
  [Net.SecurityProtocolType]::Tls

Or since this is PowerShell, you can let it parse a string for you:

[Net.ServicePointManager]::SecurityProtocol = "tls12, tls11, tls"

Then you don't technically need to know the TLS version.

I copied and pasted this from a script I created after reading this answer because I didn't want to cycle through all the available protocols to find one that worked. Of course, you could do that if you wanted to.

Final note - I have the original (minus SO edits) statement in my PowerShell profile so it's in every session I start now. It's not totally foolproof since there are still some sites that just fail but I surely see the message in question much less frequently.

One more important difference: typedefs cannot be forward declared. So for the typedef option you must #include the file containing the typedef, meaning everything that #includes your .h also includes that file whether it directly needs it or not, and so on. It can definitely impact your build times on larger projects.

Without the typedef, in some cases you can just add a forward declaration of struct Foo; at the top of your .h file, and only #include the struct definition in your .cpp file.

Here's a snippet that will walk the file tree for you:

indir = '/home/des/test'
for root, dirs, filenames in os.walk(indir):
    for f in filenames:
        print(f)
        log = open(indir + f, 'r')

how about complex types? when array contains objects... or any else

My variant:

Object.prototype.copy = function(){
    var v_newObj = {};
    for(v_i in this)
        v_newObj[v_i] = (typeof this[v_i]).contains(/^(array|object)$/) ? this[v_i].copy() : this[v_i];
    return v_newObj;
}

Array.prototype.copy = function(){
    var v_newArr = [];
    this.each(function(v_i){
        v_newArr.push((typeof v_i).contains(/^(array|object)$/) ? v_i.copy() : v_i);
    });
    return v_newArr;
}

It's not final version, just an idea.

PS: method each and contains are prototypes also.

You can easily import your model and run this:

from models import User

# User is the name of table that has a column name
users = User.query.all()

for user in users:
    print user.name

Rand() does generate a uniform distribution of random numbers between 0 and 1, but the norminv (or norm.inv) function is taking the uniform distributed Rand() as an input to generate the normally distributed sample set.

You need to modify AndroidManifest.xml as Intrications (previously Ashton) mentioned and make sure the activity handles the onConfigurationChanged event as you want it handled. This is how it should look:

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

You can use the cherry-pick to get the particular bug fix commit(s)

$ git checkout branch
$ git cherry-pick bugfix

The Uniform Resource Identifier is a unique pointer to the resource. A poorly form URI doesn't point to the resource and therefore performing a GET on it will not return a resource. 404 means The server has not found anything matching the Request-URI. If you put in the wrong URI or bad URI that is your problem and the reason you didn't get to a resource whether a HTML page or IMG.

If you are interested in portability between different SQL servers you should use ANSI SQL queries. String escaping in ANSI SQL is done by using double quotes ("). Unfortunately, this escaping method is not portable to MySQL, unless it is set in ANSI compatibility mode.

Personally, I always start my MySQL server with the --sql-mode='ANSI' argument since this allows for both methods for escaping. If you are writing queries that are going to be executed in a MySQL server that was not setup / is controlled by you, here is what you can do:

• Write all you SQL queries in ANSI SQL

• Enclose them in the following MySQL specific queries:

  SET @OLD_SQL_MODE=@@SQL_MODE;
  SET SESSION SQL_MODE='ANSI';
  -- ANSI SQL queries
  SET SESSION SQL_MODE=@OLD_SQL_MODE;
  

This way the only MySQL specific queries are at the beginning and the end of your .sql script. If you what to ship them for a different server just remove these 3 queries and you're all set. Even more conveniently you could create a script named: script_mysql.sql that would contain the above mode setting queries, source a script_ansi.sql script and reset the mode.

In config.inc.php in the top-level directory, set

$cfg['DefaultLang'] = 'en-utf-8'; // Language if no other language is recognized
// or
$cfg['Lang'] = 'en-utf-8'; // Force this language for all users

If Lang isn't set, you should be able to select the language in the initial welcome screen, and the language your browser prefers should be preselected there.

The Python approach to "main" is almost unique to the language(*).

The semantics are a bit subtle. The __name__ identifier is bound to the name of any module as it's being imported. However, when a file is being executed then __name__ is set to "__main__" (the literal string: __main__).

This is almost always used to separate the portion of code which should be executed from the portions of code which define functionality. So Python code often contains a line like:

#!/usr/bin/env python
from __future__ import print_function
import this, that, other, stuff
class SomeObject(object):
    pass

def some_function(*args,**kwargs):
    pass

if __name__ == '__main__':
    print("This only executes when %s is executed rather than imported" % __file__)

Using this convention one can have a file define classes and functions for use in other programs, and also include code to evaluate only when the file is called as a standalone script.

It's important to understand that all of the code above the if __name__ line is being executed, evaluated, in both cases. It's evaluated by the interpreter when the file is imported or when it's executed. If you put a print statement before the if __name__ line then it will print output every time any other code attempts to import that as a module. (Of course, this would be anti-social. Don't do that).

I, personally, like these semantics. It encourages programmers to separate functionality (definitions) from function (execution) and encourages re-use.

Ideally almost every Python module can do something useful if called from the command line. In many cases this is used for managing unit tests. If a particular file defines functionality which is only useful in the context of other components of a system then one can still use __name__ == "__main__" to isolate a block of code which calls a suite of unit tests that apply to this module.

(If you're not going to have any such functionality nor unit tests than it's best to ensure that the file mode is NOT executable).

Summary: if __name__ == '__main__': has two primary use cases:

• Allow a module to provide functionality for import into other code while also providing useful semantics as a standalone script (a command line wrapper around the functionality)
• Allow a module to define a suite of unit tests which are stored with (in the same file as) the code to be tested and which can be executed independently of the rest of the codebase.

It's fairly common to def main(*args) and have if __name__ == '__main__': simply call main(*sys.argv[1:]) if you want to define main in a manner that's similar to some other programming languages. If your .py file is primarily intended to be used as a module in other code then you might def test_module() and calling test_module() in your if __name__ == '__main__:' suite.

• (Ruby also implements a similar feature if __file__ == $0).

I have the same problem but in reverse, and the following solution. I want to put html from a div in a textarea (so I can edit some reactions on my website; I want to have the textarea in the same location.)

To put the content of this div in a textarea I use:

var content = $('#msg500').text();_x000D_
$('#msg500').wrapInner('<textarea>' + content + '</textarea>');

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div id="msg500">here some <strong>html</strong> <i>tags</i>.</div>

You actually had it correct in your third attempt.

 <select ng-model="myselect" ng-options="o as o for o in options"></select>

See a working example here: http://plnkr.co/edit/xEERH2zDQ5mPXt9qCl6k?p=preview

The trick is that AngularJS writes the keys as numbers from 0 to n anyway, and translates back when updating the model.

As a result, the HTML will look incorrect but the model will still be set properly when choosing a value. (i.e. AngularJS will translate '0' back to 'var1')

The solution by Epokk also works, however if you're loading data asynchronously you might find it doesn't always update correctly. Using ngOptions will correctly refresh when the scope changes.

As rebenvp said I used:

g++ *.cpp -o output

And then do this for output:

./output

But a better solution is to use make file. Read here to know more about make files.

Also make sure that you have added the required .h files in the .cpp files.

Main culprit for this error is logic which determines encoding when converting Stream or byte[] array to .NET string.

Using StreamReader created with 2nd constructor parameter detectEncodingFromByteOrderMarks set to true, will determine proper encoding and create string which does not break XmlDocument.LoadXml method.

public string GetXmlString(string url)
{
    using var stream = GetResponseStream(url);
    using var reader = new StreamReader(stream, true);
    return reader.ReadToEnd(); // no exception on `LoadXml`
}

Common mistake would be to just blindly use UTF8 encoding on the stream or byte[]. Code bellow would produce string that looks valid when inspected in Visual Studio debugger, or copy-pasted somewhere, but it will produce the exception when used with Load or LoadXml if file is encoded differently then UTF8 without BOM.

public string GetXmlString(string url)
{
    byte[] bytes = GetResponseByteArray(url);
    return System.Text.Encoding.UTF8.GetString(bytes); // potentially exception on `LoadXml`
}

So, in the case of your third party library, they probably use 2nd approach to decode XML stream to string, thus the exception.

Try os.path.splitext it should do what you want.

import os
print os.path.splitext('/home/user/somefile.txt')[0]+'.jpg'

I searched for hours, and I tried almost everything suggested.
This worked for almost every entity :

$input = "ažškunrukiš ? àéò ??? ©€ ?? ? ?? ? R?";


echo htmlentities($input, ENT_HTML5  , 'UTF-8');

result :

āžšķūņrūķīš ○ àéò ∀∂∋ ©€ ♣♦ ↠ ↔↛ ↙ ℜ℞rx;

\p{L} matches a single code point in the category "letter".
\p{N} matches any kind of numeric character in any script.

Source: regular-expressions.info

If you're going to work with regular expressions a lot, I'd suggest bookmarking that site, it's very useful.

Use the splice method.

ArrayName.splice(indexValueOfArray,1);

This removes 1 item from the array starting at indexValueOfArray.

Never use escape(). It's nothing to do with HTML-encoding. It's more like URL-encoding, but it's not even properly that. It's a bizarre non-standard encoding available only in JavaScript.

If you want an HTML encoder, you'll have to write it yourself as JavaScript doesn't give you one. For example:

function encodeHTML(s) {
    return s.replace(/&/g, '&amp;').replace(/</g, '&lt;').replace(/"/g, '&quot;');
}

However whilst this is enough to put your user_id in places like the input value, it's not enough for id because IDs can only use a limited selection of characters. (And % isn't among them, so escape() or even encodeURIComponent() is no good.)

You could invent your own encoding scheme to put any characters in an ID, for example:

function encodeID(s) {
    if (s==='') return '_';
    return s.replace(/[^a-zA-Z0-9.-]/g, function(match) {
        return '_'+match[0].charCodeAt(0).toString(16)+'_';
    });
}

But you've still got a problem if the same user_id occurs twice. And to be honest, the whole thing with throwing around HTML strings is usually a bad idea. Use DOM methods instead, and retain JavaScript references to each element, so you don't have to keep calling getElementById, or worrying about how arbitrary strings are inserted into IDs.

eg.:

function addChut(user_id) {
    var log= document.createElement('div');
    log.className= 'log';
    var textarea= document.createElement('textarea');
    var input= document.createElement('input');
    input.value= user_id;
    input.readonly= True;
    var button= document.createElement('input');
    button.type= 'button';
    button.value= 'Message';

    var chut= document.createElement('div');
    chut.className= 'chut';
    chut.appendChild(log);
    chut.appendChild(textarea);
    chut.appendChild(input);
    chut.appendChild(button);
    document.getElementById('chuts').appendChild(chut);

    button.onclick= function() {
        alert('Send '+textarea.value+' to '+user_id);
    };

    return chut;
}

You could also use a convenience function or JS framework to cut down on the lengthiness of the create-set-appends calls there.

ETA:

I'm using jQuery at the moment as a framework

OK, then consider the jQuery 1.4 creation shortcuts, eg.:

var log= $('<div>', {className: 'log'});
var input= $('<input>', {readOnly: true, val: user_id});
...

The problem I have right now is that I use JSONP to add elements and events to a page, and so I can not know whether the elements already exist or not before showing a message.

You can keep a lookup of user_id to element nodes (or wrapper objects) in JavaScript, to save putting that information in the DOM itself, where the characters that can go in an id are restricted.

var chut_lookup= {};
...

function getChut(user_id) {
    var key= '_map_'+user_id;
    if (key in chut_lookup)
        return chut_lookup[key];
    return chut_lookup[key]= addChut(user_id);
}

(The _map_ prefix is because JavaScript objects don't quite work as a mapping of arbitrary strings. The empty string and, in IE, some Object member names, confuse it.)

A StreamReader is for text, not plain bytes. Don't use a StreamReader, and instead read directly from the underlying stream.

The user agent string is a text that the browsers themselves send to the webserver to identify themselves, so that websites can send different content based on the browser or based on browser compatibility.

Mozilla is a browser rendering engine (the one at the core of Firefox) and the fact that Chrome and IE contain the string Mozilla/4 or /5 identifies them as being compatible with that rendering engine.

Your sample code seems to be OK. Thus, the root problem needs to be dug up somehow. Let's eliminate chance for typos in the script. First off, make sure you put Set-Strictmode -Version 2.0 in the beginning of your script. This will help you to catch misspelled variable names. Like so,

# Test.ps1
set-strictmode -version 2.0 # Comment this line and no error will be reported.
$foo = "bar"
set-content -path ./test.txt -value $fo # Error! Should be "$foo"

PS C:\temp> .\test.ps1
The variable '$fo' cannot be retrieved because it has not been set.
At C:\temp\test.ps1:3 char:40
+ set-content -path ./test.txt -value $fo <<<<
    + CategoryInfo          : InvalidOperation: (fo:Token) [], RuntimeException
    + FullyQualifiedErrorId : VariableIsUndefined

The next part about question marks sounds like you have a problem with Unicode. What's the output when you type the file with Powershell like so,

$file = "\\server\share\file.txt"
cat $file

$(document).ready(function() {
  //...
//clear on focus
$('.input').focus(function() {
    $('.input').val("");
});
   //clear when submitted
$('.button').click(function() {
    $('.input').val("");
});

});

The trick is to acquire all the necessary iframe events from an external script. For instance, you have a script which creates the iFrame using document.createElement; in this same script you temporarily have access to the contents of the iFrame.

var dFrame = document.createElement("iframe");
dFrame.src = "http://www.example.com";
// Acquire onload and resize the iframe
dFrame.onload = function()
{
    // Setting the content window's resize function tells us when we've changed the height of the internal document
    // It also only needs to do what onload does, so just have it call onload
    dFrame.contentWindow.onresize = function() { dFrame.onload() };
    dFrame.style.height = dFrame.contentWindow.document.body.scrollHeight + "px";
}
window.onresize = function() {
    dFrame.onload();
}

This works because dFrame stays in scope in those functions, giving you access to the external iFrame element from within the scope of the frame, allowing you to see the actual document height and expand it as necessary. This example will work in firefox but nowhere else; I could give you the workarounds, but you can figure out the rest ;)

Cell spacing and margin is the space between cells.

Cell padding is space inside cells, between the cell border (even if invisible) and the cell content, such as text.

The only way I was able to get autoplay to work was to use the iframe player api.

<div id="ytplayer"></div>
<script>
// Load the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// Replace the 'ytplayer' element with an <iframe> and
// YouTube player after the API code downloads.
var player;
function onYouTubePlayerAPIReady() {
    player = new YT.Player('ytplayer', {
        height: '480',
        width: '853',
        videoId: 'JW5meKfy3fY',
        playerVars: {
            'autoplay': 1,
            'showinfo': 0,
            'controls': 0
        }
    });
}
</script>

Since you have dynamic values, you need to use an IF or CASE for the columns to be updated. It gets kinda ugly, but it should work.

Using your example, you could do it like:

UPDATE table SET Col1 = CASE id 
                          WHEN 1 THEN 1 
                          WHEN 2 THEN 2 
                          WHEN 4 THEN 10 
                          ELSE Col1 
                        END, 
                 Col2 = CASE id 
                          WHEN 3 THEN 3 
                          WHEN 4 THEN 12 
                          ELSE Col2 
                        END
             WHERE id IN (1, 2, 3, 4);

For osX Mavericks Users you can install the ipa-file with the Apple Configurator. (Instead of the iPhone configuration utility, which crashes on OSX 10.9)

So to make your expression work, changing && for -a will do the trick.

It is correct like this:

 if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
 then  ....

or like

 if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
 then  ....

or even

 if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
 then  ....

You can find further details in this question bash : Multiple Unary operators in if statement and some references given there like What is the difference between test, [ and [[ ?.

You can do this with this library. https://github.com/itmor/events-js

const events = new Events();

events.add({  
  blockIsHidden: () =>  {
    if ($('div').css('display') === 'none') return true;
  }
});

function printText () {
  console.log('The block has become hidden!');
}

events.on('blockIsHidden', printText);

Be aware when using fileInputStream.available() the returned integer does not have to represent the actual file size, but rather the guessed amount of bytes the system should be able to read from the stream without blocking IO. A safe and simple way could look like this

public String readStringFromInputStream(FileInputStream fileInputStream) {
    StringBuffer stringBuffer = new StringBuffer();
    try {
        byte[] buffer;
        while (fileInputStream.available() > 0) {
            buffer = new byte[fileInputStream.available()];
            fileInputStream.read(buffer);
            stringBuffer.append(new String(buffer, "ISO-8859-1"));
        }
    } catch (FileNotFoundException e) {
    } catch (IOException e) { }
    return stringBuffer.toString();
}

It should be considered that this approach is not suitable for multi-byte character encodings like UTF-8.

I'm late to the party, but after facing this issue today, I found this answer to be very good:

String asciiName = Normalizer.normalize(unicodeName, Normalizer.Form.NFD)
    .replaceAll("[^\\p{ASCII}]", "");

A good solution here for VSCode users, if a string breaking down into multiple lines causes the problem (I faced this when I had to test a long JWT token, and somehow using template literals didn't do the trick.)

UPDATE (2019-04-22) - It sounds like you want to use uncompyle6 nowadays rather than the answers I had mentioned originally.

This sounds like it works: http://code.google.com/p/unpyc/

Issue 8 says it supports 2.7: http://code.google.com/p/unpyc/updates/list

UPDATE (2013-09-03) - As noted in the comments and in other answers, you should look at https://github.com/wibiti/uncompyle2 or https://github.com/gstarnberger/uncompyle instead of unpyc.

var user = [
  { id: 1, name: 'Siddhu' },
  { id: 2, name: 'Siddhartha' },
  { id: 3, name: 'Tiwary' }
];

var recToRemove={ id: 1, name: 'Siddhu' };

user.splice(user.indexOf(recToRemove),1)

This is because, by default, Jaxb when serializes a pojo, looks for the annotations over the public members(getters or setters) of the properties. But, you are providing annotations on fields. so, either change and set the annotations on setters or getters of properties, or sets the XmlAccessortype to field.

Option 1::

@XmlRootElement(name = "fields")
@XmlAccessorType(XmlAccessType.FIELD)
public class Fields {

        @XmlElement(name = "field")
        List<Field> fields = new ArrayList<Field>();
        //getter, setter
}

@XmlAccessorType(XmlAccessType.FIELD)
public class Field {

       @XmlAttribute(name = "mappedField")
       String mappedField;
       //getter,setter
}

Option 2::

@XmlRootElement(name = "fields")
public class Fields {

        List<Field> fields = new ArrayList<Field>();

        @XmlElement(name = "field")
        public List<Field> getFields() {

        }

        //setter
}

@XmlAccessorType(XmlAccessType.FIELD)
public class Field {

       String mappedField;

       @XmlAttribute(name = "mappedField")
       public String getMappedField() {

       }

        //setter
}

If you call this as a standalone function like so:

Foo();

Executing this function will add two properties to the window object (A and B). It adds it to the window because window is the object that called the function when you execute it like that, and this in a function is the object that called the function. In Javascript at least.

Now, call it like this with new:

var bar = new Foo();

What happens when you add new to a function call is that a new object is created (just var bar = new Object()) and that the this within the function points to the new Object you just created, instead of to the object that called the function. So bar is now an object with the properties A and B. Any function can be a constructor, it just doesn't always make sense.

In IntelliJ IDEA 14, it has moved to: File -> Settings -> Editor -> General -> "Show quick doc on mouse move"

>>> the_list =[ ['a','b'], ['a','c'], ['b''d'] ]
>>> any('c' == x[1] for x in the_list)
True

After observing number of viewers to this question I decided to conclude an answer from Vikramaditya and Sandeep.

To build the production code the first thing you have to create is production configuration with optimization packages like,

  new webpack.optimize.CommonsChunkPlugin('common.js'),
  new webpack.optimize.DedupePlugin(),
  new webpack.optimize.UglifyJsPlugin(),
  new webpack.optimize.AggressiveMergingPlugin()

Then in the package.json file you can configure the build procedure with this production configuration

"scripts": {
    "build": "NODE_ENV=production webpack --config ./webpack.production.config.js"
},

now you have to run the following command to initiate the build

npm run build

As per my production build configuration webpack will build the source to ./dist directory.

Now your UI code will be available in ./dist/ directory. Configure your server to serve these files as static assets. Done!

Dim ipAddress As IPAddress
Dim ipHostInfo As IPHostEntry = Dns.Resolve(Dns.GetHostName())
ipAddress = ipHostInfo.AddressList(0)

enumerate is what you are looking for.

You might also be interested in unpacking:

# The pattern
x, y, z = [1, 2, 3]

# also works in loops:
l = [(28, 'M'), (4, 'a'), (1990, 'r')]
for x, y in l:
    print(x)  # prints the numbers 28, 4, 1990

# and also
for index, (x, y) in enumerate(l):
    print(x)  # prints the numbers 28, 4, 1990

Also, there is itertools.count() so you could do something like

import itertools

for index, el in zip(itertools.count(), [28, 4, 1990]):
    print(el)  # prints the numbers 28, 4, 1990

Make use of find's options

There is actually no exec of /bin/ls needed;

Find has an option that does just that:

find . -maxdepth 2 -type d -ls

To see only the one level of subdirectories you are interested in, add -mindepth to the same level as -maxdepth:

find . -mindepth 2 -maxdepth 2 -type d -ls

Use output formatting

When the details that get shown should be different, -printf can show any detail about a file in custom format; To show the symbolic permissions and the owner name of the file, use -printf with %M and %u in the format.

I noticed later you want the full ownership information, which includes the group. Use %g in the format for the symbolic name, or %G for the group id (like also %U for numeric user id)

find . -mindepth 2 -maxdepth 2 -type d -printf '%M %u %g %p\n'

This should give you just the details you need, for just the right files.

I will give an example that shows actually different values for user and group:

$ sudo find /tmp -mindepth 2 -maxdepth 2 -type d -printf '%M %u %g %p\n'
drwx------ www-data  www-data /tmp/user/33
drwx------ octopussy root     /tmp/user/126
drwx------ root      root     /tmp/user/0
drwx------ siegel    root     /tmp/user/1000
drwxrwxrwt root      root     /tmp/systemd-[...].service-HRUQmm/tmp

Notes on performance

Although the execution time is mostly irrelevant for this kind of command, increase in performance is large enough here to make it worth pointing it out:

Not only do we save creating a new process for each name - a huge task - the information does not even need to be read, as find already knows it.

To had to distinct by two fields (derivative_id & vehicle_type) and to sort by cheapest car. Had to nest aggs.

GET /cars/_search

      "terms": { 
        "field": "derivative_id"
      },
      "aggs": {
        "vehicle_type": {
          "terms": {

          },
          "aggs": {
            "cheapest_vehicle": {

The following awk command prints the last N fields of each line and at the end of the line prints a new line character:

awk '{for( i=6; i<=NF; i++ ){printf( "%s ", $i )}; printf( "\n"); }'

Find below an example that lists the content of the /usr/bin directory and then holds the last 3 lines and then prints the last 4 columns of each line using awk:

No you need to select it with correct name. If you gave the table you select from an alias you can use that though.

For posterity, I didn't see okhttp mentioned. Related post.

Basically you build up the body using a MultipartBody.Builder, and then post this in a request.

Example in kotlin:

    val body = MultipartBody.Builder()
            .setType(MultipartBody.FORM)
            .addFormDataPart(
                "file", 
                file.getName(),
                RequestBody.create(MediaType.parse("image/png"), file)
            )
            .addFormDataPart("timestamp", Date().time.toString())
            .build()

    val request = Request.Builder()
            .url(url)
            .post(body)
            .build()

    httpClient.newCall(request).enqueue(object : okhttp3.Callback {
        override fun onFailure(call: Call?, e: IOException?) {
            ...
        }

        override fun onResponse(call: Call?, response: Response?) {
            ...
        }
    })

In xml, you can use ?attr/actionBarSize, but if you need access to that value in Java you need to use below code:

public int getActionBarHeight() {
        int actionBarHeight = 0;
        TypedValue tv = new TypedValue();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
            if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv,
                    true))
                actionBarHeight = TypedValue.complexToDimensionPixelSize(
                        tv.data, getResources().getDisplayMetrics());
        } else {
            actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,
                    getResources().getDisplayMetrics());
        }
        return actionBarHeight;
    }

Give a try to Mongo-hacker(node module), it alway prints pretty. https://github.com/TylerBrock/mongo-hacker

More it enhances mongo shell (supports only ver>2.4, current ver is 3.0), like

• Colorization
• Additional shell commands (count documents/count docs/etc)
• API Additions (db.collection.find({ ... }).last(), db.collection.find({ ... }).reverse(), etc)
• Aggregation Framework

I am using for while in production env, no problems yet.

You could stil use @TEMP if you quote the identifier "@TEMP":

declare @TEMP table (ID int, Name varchar(max));
insert into @temp SELECT 1 AS ID, 'a' Name;

SELECT * FROM @TEMP WHERE "@TEMP".ID  = 1 ;

Using Java 8 try with resources:

    StringBuilder stringBuilder = new StringBuilder();
    try(BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(request.getInputStream()))) {
        char[] charBuffer = new char[1024];
        int bytesRead;
        while ((bytesRead = bufferedReader.read(charBuffer)) > 0) {
            stringBuilder.append(charBuffer, 0, bytesRead);
        }
    }

For any sub domain request, use this:

RewriteEngine on 
RewriteCond %{HTTP_HOST} !^www\.band\.s\.co 
RewriteCond %{HTTP_HOST} ^(.*)\.band\.s\.co 
RewriteCond %{REQUEST_URI} !^/([a-zA-Z0-9-z\-]+) 
RewriteRule ^(.*)$ /%1/$1 [L] 

Just make some folder same as sub domain name you need. Folder must be exist like this: domain.com/sub for sub.domain.com.

import datetime
mydate = datetime.datetime.now()
mydate.strftime("%B")

Returns: December

Some more info on the Python doc website

[EDIT : great comment from @GiriB] You can also use %b which returns the short notation for month name.

mydate.strftime("%b")

For the example above, it would return Dec.

You close the second Scanner which closes the underlying InputStream, therefore the first Scanner can no longer read from the same InputStream and a NoSuchElementException results.

The solution: For console apps, use a single Scanner to read from System.in.

Aside: As stated already, be aware that Scanner#nextInt does not consume newline characters. Ensure that these are consumed before attempting to call nextLine again by using Scanner#newLine().

See: Do not create multiple buffered wrappers on a single InputStream

It defines an XML Namespace.

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

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

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

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

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

there might be a problem at your web hosting company from where you are testing the secure communication for gateway, that they might not allow you to do that.

also there might be a username, password that must be provided before connecting to remote host.

or your IP might need to be in the list of approved IP for the remote server for communication to initiate.

I found this code where date is compared in a format to compare with date field in database...may be this might be helpful to you...

When you convert the string to date using simpledateformat, it is hard to compare with the Date field in mysql databases.

So convert the java string date in the format using select STR_to_DATE('yourdate','%m/%d/%Y') --> in this format, then you will get the exact date format of mysql date field.

http://javainfinite.com/java/java-convert-string-to-date-and-compare/

Given that the remote repository has been cached via git fetch it should be possible to compare against these commits. Try the following:

$ git fetch origin
$ git diff origin/master

Just add android:gravity="right" this line parent layout this will work.

I'm not fine with solutions that iterates over a collection and inside the loop manipulating the content of even that collection. This can result in unexpected behaviour.

See also here: https://stackoverflow.com/a/2304578/655224 and in a comment the given link http://php.net/manual/en/control-structures.foreach.php#88578

So, when using foreach if seems to be OK but IMHO the much more readable and simple solution is to filter your collection to a new one.

/**
 * Filter all `selected` items
 *
 * @link https://laravel.com/docs/7.x/collections#method-filter
 */
$selected = $collection->filter(function($value, $key) {
    return $value->selected;
})->toArray();

The reason your URL is being rewritten to file///K:/AmberCRO%20SOP/2011-07-05/SOP-SOP-3.0.pdf is because you specified http://file://

The http:// at the beginning is the protocol being used, and your browser is stripping out the second colon (:) because it is invalid.

Note

If you link to something like

<a href="file:///K:/yourfile.pdf">yourfile.pdf</a>

The above represents a link to a file called k:/yourfile.pdf on the k: drive on the machine on which you are viewing the URL.

You can do this, for example the below creates a link to C:\temp\test.pdf

<a href="file:///C:/Temp/test.pdf">test.pdf</a>

By specifying file:// you are indicating that this is a local resource. This resource is NOT on the internet.

Most people do not have a K:/ drive.

But, if this is what you are trying to achieve, that's fine, but this is not how a "typical" link on a web page works, and you shouldn't being doing this unless everyone who is going to access your link has access to the (same?) K:/drive (this might be the case with a shared network drive).

You could try

<a href="file:///K:/AmberCRO-SOP/2011-07-05/SOP-SOP-3.0.pdf">test.pdf</a>
<a href="AmberCRO-SOP/2011-07-05/SOP-SOP-3.0.pdf">test.pdf</a>
<a href="2011-07-05/SOP-SOP-3.0.pdf">test.pdf</a>

Note that http://file:///K:/AmberCRO%20SOP/2011-07-05/SOP-SOP-3.0.pdf is a malformed

Adding params keyword itself shows that you can pass multiple number of parameters while calling that method which is not possible without using it. To be more specific:

static public int addTwoEach(params int[] args)
{
    int sum = 0;

    foreach (var item in args)
    {
        sum += item + 2;
    }

    return sum;
}

When you will call above method you can call it by any of the following ways:

1. addTwoEach()
2. addTwoEach(1)
3. addTwoEach(new int[]{ 1, 2, 3, 4 })

But when you will remove params keyword only third way of the above given ways will work fine. For 1st and 2nd case you will get an error.

I think you can use smtpjs.com

To add to @japher's post. If you are not particularly tied to JSON, Protocol Buffers is worth checking out.

Based on the answer by mouad, here's a more pythonic way to select the variables based on a prefix:

# All the vars that I want to get start with fruit_
fruit_apple = 1
fruit_carrot = 'f'
rotten = 666

prefix = 'fruit_'
sourcedict = locals()
fruitdict = { v[len(prefix):] : sourcedict[v]
              for v in sourcedict
              if v.startswith(prefix) }
# fruitdict = {'carrot': 'f', 'apple': 1}

You can even put that in a function with prefix and sourcedict as arguments.

Security Warning: md5(uniqid(rand(), TRUE)) is not a secure way to generate random numbers. See this answer for more information and a solution that leverages a cryptographically secure random number generator.

Looks like you need an else with your if.

if (!isset($_SESSION['token'])) {
    $token = md5(uniqid(rand(), TRUE));
    $_SESSION['token'] = $token;
    $_SESSION['token_time'] = time();
}
else
{
    $token = $_SESSION['token'];
}

You need to move the unique_ptr:

vec.push_back(std::move(ptr2x));

unique_ptr guarantees that a single unique_ptr container has ownership of the held pointer. This means that you can't make copies of a unique_ptr (because then two unique_ptrs would have ownership), so you can only move it.

Note, however, that your current use of unique_ptr is incorrect. You cannot use it to manage a pointer to a local variable. The lifetime of a local variable is managed automatically: local variables are destroyed when the block ends (e.g., when the function returns, in this case). You need to dynamically allocate the object:

std::unique_ptr<int> ptr(new int(1));

In C++14 we have an even better way to do so:

make_unique<int>(5);

Firebase listeners fire for both the initial data and any changes.

If you're looking to synchronize the data in a collection, use ChildEventListener. If you're looking to synchronize a single object, use ValueEventListener. Note that in both cases you're not "getting" the data. You're synchronizing it, which means that the callback may be invoked multiple times: for the initial data and whenever the data gets updated.

This is covered in Firebase's quickstart guide for Android. The relevant code and quote:

FirebaseRef.child("message").addValueEventListener(new ValueEventListener() {
  @Override
  public void onDataChange(DataSnapshot snapshot) {
    System.out.println(snapshot.getValue());  //prints "Do you have data? You'll love Firebase."
  }
  @Override
  public void onCancelled(DatabaseError databaseError) {        
  }
});

In the example above, the value event will fire once for the initial state of the data, and then again every time the value of that data changes.

Please spend a few moments to go through that quick start. It shouldn't take more than 15 minutes and it will save you from a lot of head scratching and questions. The Firebase Android Guide is probably a good next destination, for this question specifically: https://firebase.google.com/docs/database/android/read-and-write

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.

SHA1 is a one way hash. So you can not really revert it.

That's why applications use it to store the hash of the password and not the password itself.

Like every hash function SHA-1 maps a large input set (the keys) to a smaller target set (the hash values). Thus collisions can occur. This means that two values of the input set map to the same hash value.

Obviously the collision probability increases when the target set is getting smaller. But vice versa this also means that the collision probability decreases when the target set is getting larger and SHA-1's target set is 160 bit.

Jeff Preshing, wrote a very good blog about Hash Collision Probabilities that can help you to decide which hash algorithm to use. Thanks Jeff.

In his blog he shows a table that tells us the probability of collisions for a given input set.

As you can see the probability of a 32-bit hash is 1 in 2 if you have 77163 input values.

A simple java program will show us what his table shows:

public class Main {

    public static void main(String[] args) {
        char[] inputValue = new char[10];

        Map<Integer, String> hashValues = new HashMap<Integer, String>();

        int collisionCount = 0;

        for (int i = 0; i < 77163; i++) {
            String asString = nextValue(inputValue);
            int hashCode = asString.hashCode();
            String collisionString = hashValues.put(hashCode, asString);
            if (collisionString != null) {
                collisionCount++;
                System.out.println("Collision: " + asString + " <-> " + collisionString);
            }
        }

        System.out.println("Collision count: " + collisionCount);
    }

    private static String nextValue(char[] inputValue) {
        nextValue(inputValue, 0);

        int endIndex = 0;
        for (int i = 0; i < inputValue.length; i++) {
            if (inputValue[i] == 0) {
                endIndex = i;
                break;
            }
        }

        return new String(inputValue, 0, endIndex);
    }

    private static void nextValue(char[] inputValue, int index) {
        boolean increaseNextIndex = inputValue[index] == 'z';

        if (inputValue[index] == 0 || increaseNextIndex) {
            inputValue[index] = 'A';
        } else {
            inputValue[index] += 1;
        }

        if (increaseNextIndex) {
            nextValue(inputValue, index + 1);
        }

    }

}

My output end with:

Collision: RvV <-> SWV
Collision: SvV <-> TWV
Collision: TvV <-> UWV
Collision: UvV <-> VWV
Collision: VvV <-> WWV
Collision: WvV <-> XWV
Collision count: 35135

It produced 35135 collsions and that's the nearly the half of 77163. And if I ran the program with 30084 input values the collision count is 13606. This is not exactly 1 in 10, but it is only a probability and the example program is not perfect, because it only uses the ascii chars between A and z.

Let's take the last reported collision and check

System.out.println("VvV".hashCode());
System.out.println("WWV".hashCode());

My output is

86390
86390

Conclusion:

If you have a SHA-1 value and you want to get the input value back you can try a brute force attack. This means that you have to generate all possible input values, hash them and compare them with the SHA-1 you have. But that will consume a lot of time and computing power. Some people created so called rainbow tables for some input sets. But these do only exist for some small input sets.

And remember that many input values map to a single target hash value. So even if you would know all mappings (which is impossible, because the input set is unbounded) you still can't say which input value it was.

Strictly speaking, there's no difference, since you cannot do either :)

Function overriding could have been done with a PHP extension like APD, but it's deprecated and afaik last version was unusable.

Function overloading in PHP cannot be done due to dynamic typing, ie, in PHP you don't "define" variables to be a particular type. Example:

$a=1;
$a='1';
$a=true;
$a=doSomething();

Each variable is of a different type, yet you can know the type before execution (see the 4th one). As a comparison, other languages use:

int a=1;
String s="1";
bool a=true;
something a=doSomething();

In the last example, you must forcefully set the variable's type (as an example, I used data type "something").

Another "issue" why function overloading is not possible in PHP: PHP has a function called func_get_args(), which returns an array of current arguments, now consider the following code:

function hello($a){
  print_r(func_get_args());
}

function hello($a,$a){
  print_r(func_get_args());
}

hello('a');
hello('a','b');

Considering both functions accept any amount of arguments, which one should the compiler choose?

Finally, I'd like to point out why the above replies are partially wrong; function overloading/overriding is NOT equal to method overloading/overriding.

Where a method is like a function but specific to a class, in which case, PHP does allow overriding in classes, but again no overloading, due to language semantics.

To conclude, languages like Javascript allow overriding (but again, no overloading), however they may also show the difference between overriding a user function and a method:

/// Function Overriding ///

function a(){
   alert('a');
}
a=function(){
   alert('b');
}

a(); // shows popup with 'b'


/// Method Overriding ///

var a={
  "a":function(){
    alert('a');
  }
}
a.a=function(){
   alert('b');
}

a.a(); // shows popup with 'b'

Under a modern POSIX system (i.e. Linux), you can use the sigprocmask() function.

#include <signal.h>

void block_signal(int signal_to_block /* i.e. SIGPIPE */ )
{
    sigset_t set;
    sigset_t old_state;

    // get the current state
    //
    sigprocmask(SIG_BLOCK, NULL, &old_state);

    // add signal_to_block to that existing state
    //
    set = old_state;
    sigaddset(&set, signal_to_block);

    // block that signal also
    //
    sigprocmask(SIG_BLOCK, &set, NULL);

    // ... deal with old_state if required ...
}

If you want to restore the previous state later, make sure to save the old_state somewhere safe. If you call that function multiple times, you need to either use a stack or only save the first or last old_state... or maybe have a function which removes a specific blocked signal.

For more info read the man page.

You have a few different options:

• you can use a SPA router like SammyJS, or Angularjs and ui-router, so your pages are stateful.
• use sessionStorage to store your state.
• store the values on the URL hash.

UPDATED It works fine in my case:

from selenium import webdriver

options = webdriver.ChromeOptions()
options.headless = True
driver = webdriver.Chrome(CHROMEDRIVER_PATH, options=options)

Just changed in 2020. Works fine for me.

in PowerShell enter this:

[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27", "User")

Close PowerShell and then start it again to make sure Python now runs. If it doesn’t, restart may be required.

Try this following program for 2d array in java:

public class ArrayTwo2 {
    public static void main(String[] args) throws  IOException,NumberFormatException{
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        int[][] a;
        int sum=0;
        a=new int[3][2];
        System.out.println("Enter array with 5 elements");
        for(int i=0;i<a.length;i++)
        {
            for(int j=0;j<a[0].length;j++)
            {
            a[i][j]=Integer.parseInt(br.readLine());
            }
        }
        for(int i=0;i<a.length;i++)
        {
            for(int j=0;j<a[0].length;j++)
            {
            System.out.print(a[i][j]+"  ");
            sum=sum+a[i][j];
            }
        System.out.println();   
        //System.out.println("Array Sum: "+sum);
        sum=0;
        }
    }
}

Since we're all guessing, I might as well give mine: I've always thought it stood for Python. That may sound pretty stupid -- what, P for Python?! -- but in my defense, I vaguely remembered this thread [emphasis mine]:

Subject: Claiming (?P...) regex syntax extensions

From: Guido van Rossum ([email protected])

Date: Dec 10, 1997 3:36:19 pm

I have an unusual request for the Perl developers (those that develop the Perl language). I hope this (perl5-porters) is the right list. I am cc'ing the Python string-sig because it is the origin of most of the work I'm discussing here.

You are probably aware of Python. I am Python's creator; I am planning to release a next "major" version, Python 1.5, by the end of this year. I hope that Python and Perl can co-exist in years to come; cross-pollination can be good for both languages. (I believe Larry had a good look at Python when he added objects to Perl 5; O'Reilly publishes books about both languages.)

As you may know, Python 1.5 adds a new regular expression module that more closely matches Perl's syntax. We've tried to be as close to the Perl syntax as possible within Python's syntax. However, the regex syntax has some Python-specific extensions, which all begin with (?P . Currently there are two of them:

(?P<foo>...) Similar to regular grouping parentheses, but the text
matched by the group is accessible after the match has been performed, via the symbolic group name "foo".

(?P=foo) Matches the same string as that matched by the group named "foo". Equivalent to \1, \2, etc. except that the group is referred
to by name, not number.

I hope that this Python-specific extension won't conflict with any future Perl extensions to the Perl regex syntax. If you have plans to use (?P, please let us know as soon as possible so we can resolve the conflict. Otherwise, it would be nice if the (?P syntax could be permanently reserved for Python-specific syntax extensions. (Is there some kind of registry of extensions?)

to which Larry Wall replied:

[...] There's no registry as of now--yours is the first request from outside perl5-porters, so it's a pretty low-bandwidth activity. (Sorry it was even lower last week--I was off in New York at Internet World.)

Anyway, as far as I'm concerned, you may certainly have 'P' with my blessing. (Obviously Perl doesn't need the 'P' at this point. :-) [...]

So I don't know what the original choice of P was motivated by -- pattern? placeholder? penguins? -- but you can understand why I've always associated it with Python. Which considering that (1) I don't like regular expressions and avoid them wherever possible, and (2) this thread happened fifteen years ago, is kind of odd.

$ ionic -v

I would choose this simple solution.

Summarizing it:

• Client "I want to login"
• Server generates a random number #S and sends it to the Client
• Client
  • reads username and password typed by the user
  • calculates the hash of the password, getting h(pw) (which is what is stored in the DB)
  • generates another random number #C
  • concatenates h(pw) + #S + #C and calculates its hash, call it h(all)
  • sends to the server username, #C and h(all)
• Server
  • retrieves h(pw)' for the specified username, from the DB
  • now it has all the elements to calculate h(all'), like Client did
  • if h(all) = h(all') then h(pw) = h(pw)', almost certainly

No one can repeat the request to log in as the specified user. #S adds a variable component to the hash, each time (it's fundamental). #C adds additional noise in it.

Use GNU Parallel:

(echo command1; echo command2) | parallel

The answer from ast1 is very simple and useful. It works for me, thank you so much. I just want to poin it out here, so people who need this answer can find it easily. So, here is my code from registering local and remote (push) notification.

    //1. In Appdelegate: didFinishLaunchingWithOptions add these line of codes
    let mynotif = UNUserNotificationCenter.current()
    mynotif.requestAuthorization(options: [.alert, .sound, .badge]) {(granted, error) in }//register and ask user's permission for local notification

    //2. Add these functions at the bottom of your AppDelegate before the last "}"
    func application(_ application: UIApplication, didRegister notificationSettings: UNNotificationSettings) {
        application.registerForRemoteNotifications()//register for push notif after users granted their permission for showing notification
}
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let tokenString = deviceToken.reduce("", {$0 + String(format: "%02X", $1)})
    print("Device Token: \(tokenString)")//print device token in debugger console
}
    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    print("Failed to register: \(error)")//print error in debugger console
}

Update for Docker: use the install-plugins.sh script. It takes a list of plugin names minus the '-plugin' extension. See the description here.

install-plugins.sh replaces the deprecated plugins.sh which now warns :

WARN: plugins.sh is deprecated, please switch to install-plugins.sh

To use a plugins.txt as per plugins.sh see this issue and this workaround:

RUN /usr/local/bin/install-plugins.sh $(cat /usr/share/jenkins/plugins.txt | tr '\n' ' ')

You were almost done without any changes besides how you spyOn. When you use the spy, you have two options: spyOn the App.prototype, or component component.instance().

const spy = jest.spyOn(Class.prototype, "method")

The order of attaching the spy on the class prototype and rendering (shallow rendering) your instance is important.

const spy = jest.spyOn(App.prototype, "myClickFn");
const instance = shallow(<App />);

The App.prototype bit on the first line there are what you needed to make things work. A JavaScript class doesn't have any of its methods until you instantiate it with new MyClass(), or you dip into the MyClass.prototype. For your particular question, you just needed to spy on the App.prototype method myClickFn.

jest.spyOn(component.instance(), "method")

const component = shallow(<App />);
const spy = jest.spyOn(component.instance(), "myClickFn");

This method requires a shallow/render/mount instance of a React.Component to be available. Essentially spyOn is just looking for something to hijack and shove into a jest.fn(). It could be:

A plain object:

const obj = {a: x => (true)};
const spy = jest.spyOn(obj, "a");

A class:

class Foo {
    bar() {}
}

const nope = jest.spyOn(Foo, "bar");
// THROWS ERROR. Foo has no "bar" method.
// Only an instance of Foo has "bar".
const fooSpy = jest.spyOn(Foo.prototype, "bar");
// Any call to "bar" will trigger this spy; prototype or instance

const fooInstance = new Foo();
const fooInstanceSpy = jest.spyOn(fooInstance, "bar");
// Any call fooInstance makes to "bar" will trigger this spy.

Or a React.Component instance:

const component = shallow(<App />);
/*
component.instance()
-> {myClickFn: f(), render: f(), ...etc}
*/
const spy = jest.spyOn(component.instance(), "myClickFn");

Or a React.Component.prototype:

/*
App.prototype
-> {myClickFn: f(), render: f(), ...etc}
*/
const spy = jest.spyOn(App.prototype, "myClickFn");
// Any call to "myClickFn" from any instance of App will trigger this spy.

I've used and seen both methods. When I have a beforeEach() or beforeAll() block, I might go with the first approach. If I just need a quick spy, I'll use the second. Just mind the order of attaching the spy.

EDIT: If you want to check the side effects of your myClickFn you can just invoke it in a separate test.

const app = shallow(<App />);
app.instance().myClickFn()
/*
Now assert your function does what it is supposed to do...
eg.
expect(app.state("foo")).toEqual("bar");
*/

EDIT: Here is an example of using a functional component. Keep in mind that any methods scoped within your functional component are not available for spying. You would be spying on function props passed into your functional component and testing the invocation of those. This example explores the use of jest.fn() as opposed to jest.spyOn, both of which share the mock function API. While it does not answer the original question, it still provides insight on other techniques that could suit cases indirectly related to the question.

function Component({ myClickFn, items }) {
   const handleClick = (id) => {
       return () => myClickFn(id);
   };
   return (<>
       {items.map(({id, name}) => (
           <div key={id} onClick={handleClick(id)}>{name}</div>
       ))}
   </>);
}

const props = { myClickFn: jest.fn(), items: [/*...{id, name}*/] };
const component = render(<Component {...props} />);
// Do stuff to fire a click event
expect(props.myClickFn).toHaveBeenCalledWith(/*whatever*/);

Mine was a name spacing issue. I had two files with the same name. Just renamed them and it resolved.

Always gotta check the 'stupid me' box first before looking elsewhere. : )

I created a simple extension for this (Swift 3)

extension String {
    func substring(location: Int, length: Int) -> String? {
        guard characters.count >= location + length else { return nil }
        let start = index(startIndex, offsetBy: location)
        let end = index(startIndex, offsetBy: location + length)
        return substring(with: start..<end)
    }
}

Create proxy.conf.json and paste this configuration

{  
"/api/*":
    {    
        "target": "http://localhost:7070/your api project name/",
        "secure": false,
        "pathRewrite": {"^/api" : ""}
    }
}

Replace:

let url = 'api/'+ your path;

Run from CLI:

ng serve  --host port.number —-proxy-config proxy.conf.json

Adding the following lines to a new script will clear all variables each time you rerun the script:

from IPython import get_ipython
get_ipython().magic('reset -sf')

I'm absolutely new to JS and ES, but what seems to work for me is just this:

JSON.stringify(req.body)

Let me know if there's anything wrong with it!

After many days trying, I found this solution that worked for me:

touch-action: none;
-ms-touch-action: none;

Place this at the top of your script. It will cause the script to prompt the user for a password. The resulting password can then be used elsewhere in your script via $pw.

   Param(
     [Parameter(Mandatory=$true, Position=0, HelpMessage="Password?")]
     [SecureString]$password
   )

   $pw = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($password))

If you want to debug and see the value of the password you just read, use:

   write-host $pw

Updated:

I made a library based on my gist code that generates those casting for you by using @CallbackFragment and @Callback.

https://github.com/zeroarst/callbackfragment.

And the example give you the example that send a callback from a fragment to another fragment.

Old answer:

I made a BaseCallbackFragment and annotation @FragmentCallback. It currently extends Fragment, you can change it to DialogFragment and will work. It checks the implementations with the following order: getTargetFragment() > getParentFragment() > context (activity).

Then you just need to extend it and declare your interfaces in your fragment and give it the annotation, and the base fragment will do the rest. The annotation also has a parameter mandatory for you to determine whether you want to force the fragment to implement the callback.

public class EchoFragment extends BaseCallbackFragment {

    private FragmentInteractionListener mListener;

    @FragmentCallback
    public interface FragmentInteractionListener {
        void onEcho(EchoFragment fragment, String echo);
    }
}

You can use launchd for that purpose. Launchd can be configured to automatically launch a program when a file path is modified.

For example the following launchd config plist will launch the program /usr/bin/logger when the desktop folder of my user account is modified:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Label</key>
    <string>logger</string>
    <key>ProgramArguments</key>
    <array>
        <string>/usr/bin/logger</string>
        <string>path modified</string>
    </array>
    <key>WatchPaths</key>
    <array>
        <string>/Users/sakra/Desktop/</string>
    </array>
</dict>
</plist>

To activate the config plist save it to the LaunchAgents folder in your Library folder as "logger.plist".

From the shell you can then use the command launchctl to activate the logger.plist by running:

$ launchctl load ~/Library/LaunchAgents/logger.plist

The desktop folder is now being monitored. Every time it is changed you should see an output in the system.log (use Console.app). To deactivate the logger.plist, run:

$ launchctl unload ~/Library/LaunchAgents/logger.plist

The configuration file above uses the WatchPaths option. Alternatively you can also use the QueueDirectories option. See the launchd man page for more information.

public static boolean isPalindrome(String str)
{
    int len = str.length();
    int i, j;
    j = len - 1;

    {
      if (str.charAt(i) != str.charAt(j))
      return false;
      j--;
    }
    return true;
}

When you do self.button = Button(...).grid(...), what gets assigned to self.button is the result of the grid() command, not a reference to the Button object created.

You need to assign your self.button variable before packing/griding it. It should look something like this:

self.button = Button(self,text="Click Me",command=self.color_change,bg="blue")
self.button.grid(row = 2, column = 2, sticky = W)

The CSS solution for Angular Bootstrap is

::ng-deep .tooltip-inner {
  white-space: pre-wrap;
}

No need to use a parent element or class selector if you don't need to restrict it's use. Copy/Pasta, and this rule will apply to all sub-components

You can give like this

public static function getAll()
{

    return $posts = $this->all()->take(2)->get();

}

And when you call statically inside your controller function also..

It's good practise to extend from a baseController and implement some base functions implement a function to check if the user instance is null like this if the user form the Userinterface then there is no user logged in

/**

*/
class BaseController extends AbstractController
{

    /**
     * @return User

     */
    protected function getUser(): ?User
    {
        return parent::getUser();
    }

    /**
     * @return bool
     */
    protected function isUserLoggedIn(): bool
    {
        return $this->getUser() instanceof User;
    }
}

You already has this (that's what you entered) parse will parse a date into a giving format and print the full date object (toString).

Using management studio the procedure can be done as follows

1. right click on the Databases container within object explorer
2. from context menu select Restore database
3. Specify To Database as either a new or existing database
4. Specify Source for restore as from device
5. Select Backup media as File
6. Click the Add button and browse to the location of the BAK file

refer

You'll need to specify the WITH REPLACE option to overwrite the existing adventure_second database with a backup taken from a different database.

Click option menu and tick Overwrite the existing database(With replace)

Have you tried git push? gitref.org has a nice section dealing with remote repositories.

You can also get help from the command line using the --help option. For example:

% git push --help

NAME
       git-push - Update remote refs along with associated objects

SYNOPSIS
       git push [--all | --mirror | --tags] [-n | --dry-run] [--receive-pack=<git-receive-pack>]
                  [--repo=<repository>] [-f | --force] [-v | --verbose] [-u | --set-upstream]
                  [<repository> [<refspec>...]]

In windows all you have to do is to go to windows search Allow an app through Windows Firewall.click on Allow another app select Apache and mark public and private both . Open cmd by pressing windows button+r write cmd than in cmd write ipconfig find out your ip . than open up your browser write down your ip http://172.16..x and you will be on the xampp startup page.if you want to access your local site simply put / infront of your ip e.g http://192.168.1.x/yousite. Now you are able to access your website in private network computers .

i hope this will resolve your problem

You can also use meta-annotations to externalize the configuration. For example:

@RunWith(SpringJUnit4ClassRunner.class)
@DefaultTestAnnotations
public class ExampleApplicationTests { 
   ...
}

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
@SpringApplicationConfiguration(classes = ExampleApplication.class)
@TestPropertySource(locations="classpath:test.properties")
public @interface DefaultTestAnnotations { }

Do I need Class elements in persistence.xml?

No, you don't necessarily. Here is how you do it in Eclipse (Kepler tested):

Right click on the project, click Properties, select JPA, in the Persistence class management tick Discover annotated classes automatically.

If you are running the .java file in Eclipse you need to add the resource path in the build path . after that you will not see this error

Why don't you create a function or class for this navigation and put there active page as a parameter? This way you'd call it as, for example:

$navigation = new Navigation( 1 );

or

$navigation = navigation( 1 );

check for null or undefined in all cases a_string

if (a_string && typeof a_string === 'string') {
    // this is a string and it is not null or undefined.
}

Just Press Alt + Command + Enter to open the Assistant editor. Assistant Editor will open up the Timeline view. Timeline by default shows your console output.

Additionally You can add any line to Timeline view by pressing the small circle next to the eye icon in the results area. This will enable history for this expression. So you can see the output of the variable over last 30 secs (you can change this as well) of execution.

I would do something like the following:

INSERT INTO cache VALUES (key, generation)
ON DUPLICATE KEY UPDATE (key = key, generation = generation + 1);

Setting the generation value to 0 in code or in the sql but the using the ON DUP... to increment the value. I think that's the syntax anyway.

If you got "Error is not recoverable: exiting now" You might have specified incorrect path references.

[me@host ~]$ tar -xvf nameOfMyTar.tar -C /someSubDirectory/
tar: /someSubDirectory: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
[me@host ~]$

Make sure you provide correct relative or absolute directory references e.g.:

[me@host ~]$ tar -xvf ./nameOfMyTar.tar -C ./someSubDirectory/
./foo/
./bar/
[me@host ~]$

I am the creator of PowerMock so obviously I must recommend that! :-)

PowerMock extends both EasyMock and Mockito with the ability to mock static methods, final and even private methods. The EasyMock support is complete, but the Mockito plugin needs some more work. We are planning to add JMock support as well.

PowerMock is not intended to replace other frameworks, rather it can be used in the tricky situations when other frameworks does't allow mocking. PowerMock also contains other useful features such as suppressing static initializers and constructors.

You can use getRawValue()

this.formGroup.getRawValue().attribute

require() is a way to import some module on the run time and it equally qualifies for static analysis like import if used with string literal paths. This is required by bundler to pick dependencies for the bundle.

const defaultOne = require('path/to/component').default;
const NamedOne = require('path/to/component').theName;

For dynamic module resolution with complete static analysis support, first index modules in an indexer(index.js) and import indexer in host module.

// index.js
export { default as ModuleOne } from 'path/to/module/one';
export { default as ModuleTwo } from 'path/to/module/two';
export { SomeNamedModule } from 'path/to/named/module';

// host.js
import * as indexer from 'index';
const moduleName = 'ModuleOne';
const Module = require(indexer[moduleName]);

Selection is its own object within VBA. It functions much like a Range object.

Selection and Range do not share all the same properties and methods, though, so for ease of use it might make sense just to create a range and set it equal to the Selection, then you can deal with it programmatically like any other range.

Dim myRange as Range
Set myRange = Selection

Both the regex and included files are good methods, and I frequently use those. But another alternative is to use a "named location", which is a useful approach in many situations — especially more complicated ones. The official "If is Evil" page shows essentially the following as a good way to do things:

error_page 418 = @common_location;
location /first/location/ {
    return 418;
}
location /second/location/ {
    return 418;
}
location @common_location {
    # The common configuration...
}

There are advantages and disadvantages to these various approaches. One big advantage to a regex is that you can capture parts of the match and use them to modify the response. Of course, you can usually achieve similar results with the other approaches by either setting a variable in the original block or using map. The downside of the regex approach is that it can get unwieldy if you want to match a variety of locations, plus the low precedence of a regex might just not fit with how you want to match locations — not to mention that there are apparently performance impacts from regexes in some cases.

The main advantage of including files (as far as I can tell) is that it is a little more flexible about exactly what you can include — it doesn't have to be a full location block, for example. But it's also just subjectively a bit clunkier than named locations.

Also note that there is a related solution that you may be able to use in similar situations: nested locations. The idea is that you would start with a very general location, apply some configuration common to several of the possible matches, and then have separate nested locations for the different types of paths that you want to match. For example, it might be useful to do something like this:

location /specialpages/ {
    # some config
    location /specialpages/static/ {
        try_files $uri $uri/ =404;
    }
    location /specialpages/dynamic/ {
        proxy_pass http://127.0.0.1;
    }
}

Map does not supports duplicate keys. you can use collection as value against same key.

Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value.

Documentation

you can use any kind of List or Set implementation according to your requirement.

If your values might be also duplicate you can go with ArrayList or LinkedList, in case values are unique you can use HashSet or TreeSet etc.

Also In google guava collection library Multimap is available, it is a collection that maps keys to values, similar to Map, but in which each key may be associated with multiple values. You can visualize the contents of a multimap either as a map from keys to nonempty collections of values:

a ? 1, 2
b ? 3  

Example -

ListMultimap<String, String> multimap = ArrayListMultimap.create();
multimap.put("a", "1");
multimap.put("a", "2");
multimap.put("c", "3");

String str_date = "11-June-07";
DateFormat formatter;
Date date;
formatter = new SimpleDateFormat("dd-MMM-yy");
date = formatter.parse(str_date);

is null is the syntax I use for such things, when COALESCE is of no help.

Try:

if (@zipCode is null)
  begin
    ([Portal].[dbo].[Address].Position.Filter(@radiusBuff) = 1)   
  end
else 
  begin
    ([Portal].[dbo].[Address].PostalCode=@zipCode )
  end  

SELECT TRUNC(SYSDATE,'D') "1ST_DAY", TRUNC(SYSDATE,'D') + 6 LAST_DAY FROM DUAL

I like ranges for this:

def first_half(list)
  list[0...(list.length / 2)]
end

def last_half(list)
  list[(list.length / 2)..list.length]
end

However, be very careful about whether the endpoint is included in your range. This becomes critical on an odd-length list where you need to choose where you're going to break the middle. Otherwise you'll end up double-counting the middle element.

The above example will consistently put the middle element in the last half.

It is probably not the best thing to do. You need to at least check out your PHP error log for things going wrong ;)

$ git clone --no-hardlinks /path/to/repo

The above command uses POSIX path notation for the directory with your git repository. For Windows it is (directory C:/path/to/repo contains .git directory):

C:\some\dir\> git clone --local file:///C:/path/to/repo my_project

The repository will be clone to C:\some\dir\my_project. If you omit file:/// part then --local option is implied.

In order to create an anonymous type (or any type) with a property that has a reserved keyword as its name in C#, you can prepend the property name with an at sign, @:

Html.BeginForm("Foo", "Bar", FormMethod.Post, new { @class = "myclass"})

For VB.NET this syntax would be accomplished using the dot, ., which in that language is default syntax for all anonymous types:

Html.BeginForm("Foo", "Bar", FormMethod.Post, new with { .class = "myclass" })

It's treating the string application as your URL.
This means your shell isn't parsing the command correctly.
My guess is that you copied the string from somewhere, and that when you pasted it, you got some characters that looked like regular quotes, but weren't.
Try retyping the command; you'll only get valid characters from your keyboard. I bet you'll get a much different result from what looks like the same query. As this is probably a shell problem and not a 'curl' problem (you didn't build cURL yourself from source, did you?), it might be good to mention whether you're on Linux/Windows/etc.

I demonstrate how to receive a string, for example "-484876800000" and tryparse the string to make sure it can be assigned to a long. I calculate the Date from universaltime and return a string. When you convert a string to a number, you must decide the numeric type and precision and test if the string data can be parse, otherwise, it will throw and error.

        if ($result -eq 1)
        {
            $val=$returnedLong/1000.0
            $retVal=$epoch.AddSeconds($val).ToString("yyyy-MM-dd")
        }
    }
    else
    {
        $retVal=$null
    }
    return($retVal)
 }

Note: This is Flask specific!

I know this post is quite old, but there are better methods of doing this in the newer versions of Flask using context processors.

Variables can easily be created:

@app.context_processor
def example():
    return dict(myexample='This is an example')

The above can be used in a Jinja2 template with Flask like so:

{{ myexample }}

(Which outputs This is an example)

As well as full fledged functions:

@app.context_processor
def utility_processor():
    def format_price(amount, currency=u'€'):
        return u'{0:.2f}{1}'.format(amount, currency)
    return dict(format_price=format_price)

The above when used like so:

{{ format_price(0.33) }}

(Which outputs the input price with the currency symbol)

Alternatively, you can use jinja filters, baked into Flask. E.g. using decorators:

@app.template_filter('reverse')
def reverse_filter(s):
    return s[::-1]

Or, without decorators, and manually registering the function:

def reverse_filter(s):
    return s[::-1]
app.jinja_env.filters['reverse'] = reverse_filter

Filters applied with the above two methods can be used like this:

{% for x in mylist | reverse %}
{% endfor %}

There are several ways you can do that:

1. Go into node_modules/@angular/core/package.json and check version field.

2. If you need to use it in your code, you can import it from the @angular/core:

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

3. Inspect the rendered DOM - Angular adds the version to the main component element:

   <my-app ng-version="4.1.3">

Within your click handler, the mistake is the .validate() method; it only initializes the plugin, it does not validate the form.

To eliminate the need to have a submit button within the form, use .valid() to trigger a validation check...

$('#btn').on('click', function() {
    $("#form1").valid();
});

jsFiddle Demo

.validate() - to initialize the plugin (with options) once on DOM ready.

.valid() - to check validation state (boolean value) or to trigger a validation test on the form at any time.

Otherwise, if you had a type="submit" button within the form container, you would not need a special click handler and the .valid() method, as the plugin would capture that automatically.

Demo without click handler

EDIT:

You also have two issues within your HTML...

<input id="field1" type="text" class="required">

• You don't need class="required" when declaring rules within .validate(). It's redundant and superfluous.

• The name attribute is missing. Rules are declared within .validate() by their name. The plugin depends upon unique name attributes to keep track of the inputs.

Should be...

<input name="field1" id="field1" type="text" />

string [] temp = new string[] {"1","2","3"};
List<string> temp2 = temp.ToList();

TextAppearance.Holo.Widget.ActionBar.Title appears to have been added in API Level 13. Make sure your build target is set to 13, not just 11.

This is the role of the subset() function:

> dat <- data.frame(A=c(1,2),B=c(3,4),C=c(5,6),D=c(7,7),E=c(8,8),F=c(9,9)) 
> subset(dat, select=c("A", "B"))
  A B

try use base64 image string.

NSData* data = UIImageJPEGRepresentation(image, 1.0f);

NSString *strEncoded = [data base64Encoding];   

<img src='data:image/png;base64,%@ '/>,strEncoded

SUM is an aggregate function. It will calculate the total for each group. + is used for calculating two or more columns in a row.

Consider this example,

ID  VALUE1  VALUE2
===================
1   1       2
1   2       2
2   3       4
2   4       5

SELECT  ID, SUM(VALUE1), SUM(VALUE2)
FROM    tableName
GROUP   BY ID

will result

ID, SUM(VALUE1), SUM(VALUE2)
1   3           4
2   7           9

SELECT  ID, VALUE1 + VALUE2
FROM    TableName

will result

ID, VALUE1 + VALUE2
1   3
1   4
2   7
2   9

SELECT  ID, SUM(VALUE1 + VALUE2)
FROM    tableName
GROUP   BY ID

will result

ID, SUM(VALUE1 + VALUE2)
1   7
2   16

I cannot solve it with source ./myscript.sh. It says the source not found error.
Failed also when using . ./myscript.sh. It gives can't open myscript.sh.

So my option is put it in a text file to be called in the next script.

#!/bin/sh
echo "Perform Operation in su mode"
echo "ARCH=arm" >> environment.txt
echo "Export ARCH=arm Executed"
export PATH="/home/linux/Practise/linux-devkit/bin/:$PATH"
echo "Export path done"
export "CROSS_COMPILE='/home/linux/Practise/linux-devkit/bin/arm-arago-linux-gnueabi-' ## What's next to -?" >> environment.txt
echo "Export CROSS_COMPILE done"
# continue your compilation commands here
...

Tnen call it whenever is needed:

while read -r line; do
    line=$(sed -e 's/[[:space:]]*$//' <<<${line})
    var=`echo $line | cut -d '=' -f1`; test=$(echo $var)
    if [ -z "$(test)" ];then eval export "$line";fi
done <environment.txt

I have used this:

mongorestore -d databasename -c file.bson fullpath/file.bson

1.copy the file path and file name from properties (try to put all bson files in different folder), 2.use this again and again with changing file name only.

I think the best and cleanest solution you can imagine is this:

@Component( {
  selector: 'app-my-component',
  template: `<p>{{ myData?.anyfield }}</p>`,
  styles: [ '' ]
} )
export class MyComponent implements OnInit {
  private myData;

  constructor( private myService: MyService ) { }

  ngOnInit( ) {
    /* 
      async .. await 
      clears the ExpressionChangedAfterItHasBeenCheckedError exception.
    */
    this.myService.myObservable.subscribe(
      async (data) => { this.myData = await data }
    );
  }
}

Tested with Angular 5.2.9

Yes, should try reinstall mysql, but use the --reinstall flag to force a package reconfiguration. So the operating system service configuration is not skipped:

sudo apt --reinstall install mysql-server

<br>between <li></li> line entries seems to work perfectly well in all web browsers that I've tried, but it fails to pass the on-line W3C CSS3 checker. It gives me precisely the line spacing I am after. As far as I am concerned, since it undoubtedly works, I am persisting in using it, whatever W3C says, until someone can come up with a good legal alternative.

In kotlin

print()

The print statement prints everything inside it onto the screen. The print statements internally call System.out.print.

println()

The println statement appends a newline at the end of the output.

With numeric values you can avoid a temporary variable by using bitwise xor

list[x] = list[x] ^ list[y];
list[y] = list[y] ^ list[x];
list[x] = list[x] ^ list[y];

or an arithmetic sum (noting that this only works if x + y is less than the maximum value for the data type)

list[x] = list[x] + list[y];
list[y] = list[x] - list[y];
list[x] = list[x] - list[y];

In the latest Mac OS You can use shift + home or shift + end

You need to specify the encoding of the InputStreamReader using the Charset parameter.

Charset inputCharset = Charset.forName("ISO-8859-1");
InputStreamReader isr = new InputStreamReader(fis, inputCharset));

This is work for me. i hope to help you.

This worked for me:

SELECT *
FROM your_table
WHERE id IN (
    SELECT MAX(id)
    FROM your_table
    GROUP BY name
);

I had the same problem, and in my case, the solution was updating the usb-serial driver using windows update on windows 10 device's manager. There was no need to download a especific driver, I just let windows update find a suitable driver.

Step 1 :

Add this in htaccess file

<IfModule mod_rewrite.c> 
RewriteEngine On 
#RewriteBase / 

RewriteCond %{REQUEST_FILENAME} !-f 
RewriteRule ^ index.php [QSA,L] 
</IfModule>

Step 2 :

Remove index.php in codeigniter config

$config['base_url'] = ''; 
$config['index_page'] = '';

Step 3 :

Allow overriding htaccess in Apache Configuration (Command)

sudo nano /etc/apache2/apache2.conf and edit the file & change to

AllowOverride All

for www folder

Step 4 :

Enabled apache mod rewrite (Command)

sudo a2enmod rewrite

Step 5 :

Restart Apache (Command)

sudo /etc/init.d/apache2 restart

For users of modern DataTables (1.10 and above), all the answers and examples on this page are for the old api, not the new. I had a very hard time finding a newer example but finally did find this DT forum post (TL;DR for most folks) which led me to this concise example.

The example code worked for me after I finally noticed the $() selector syntax immediately surrounding the html string. You have to add a node not a string.

That example really is worth looking at but, in the spirit of SO, if you just want to see a snippet of code that works:

var table = $('#example').DataTable();
  table.rows.add( $(
          '<tr>'+
          '  <td>Tiger Nixon</td>'+
          '  <td>System Architect</td>'+
          '  <td>Edinburgh</td>'+
          '  <td>61</td>'+
          '  <td>2011/04/25</td>'+
          '  <td>$3,120</td>'+
          '</tr>'
  ) ).draw();

The careful reader might note that, since we are adding only one row of data, that table.row.add(...) should work as well and did for me.

It's not supported correctly yet.

Chrome 31 (and possibly an earlier version) supports some parts of the attribute, but it is not fully supported.

This is kind of a hack, but does seem to work. Below are the steps and an example of modifying a table type. One note is the sp_refreshsqlmodule will fail if the change you made to the table type is a breaking change to that object, typically a procedure.

1. Use sp_rename to rename the table type, I typically just add z to the beginning of the name.
2. Create a new table type with the original name and any modification you need to make to the table type.
3. Step through each dependency and run sp_refreshsqlmodule on it.
4. Drop the renamed table type.

EXEC sys.sp_rename 'dbo.MyTableType', 'zMyTableType';
GO
CREATE TYPE dbo.MyTableType AS TABLE(
    Id INT NOT NULL,
    Name VARCHAR(255) NOT NULL
);
GO
DECLARE @Name NVARCHAR(776);

DECLARE REF_CURSOR CURSOR FOR
SELECT referencing_schema_name + '.' + referencing_entity_name
FROM sys.dm_sql_referencing_entities('dbo.MyTableType', 'TYPE');

OPEN REF_CURSOR;

FETCH NEXT FROM REF_CURSOR INTO @Name;
WHILE (@@FETCH_STATUS = 0)
BEGIN
    EXEC sys.sp_refreshsqlmodule @name = @Name;
    FETCH NEXT FROM REF_CURSOR INTO @Name;
END;

CLOSE REF_CURSOR;
DEALLOCATE REF_CURSOR;
GO
DROP TYPE dbo.zMyTableType;
GO

WARNING:

This can be destructive to your database, so you'll want to test this on a development environment first.

Answer is you just drag and drop folder over the project and click copy.

I have created usable extension for UIView to take screenshot in Swift:

extension UIView{

var screenshot: UIImage{

    UIGraphicsBeginImageContext(self.bounds.size);
    let context = UIGraphicsGetCurrentContext();
    self.layer.renderInContext(context)
    let screenShot = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return screenShot
}
}

To use it just type:

let screenshot = view.screenshot

Seem like the input type number does not support size attribute or it's not compatible along browsers, you can set it through CSS instead:

input[type=number]{
    width: 80px;
} 

Updated Fiddle

3 steps:

1. Check the sorce code (HTML) of YouTube, you'll get the link like this (http%253A%252F%252Fo-o.preferred.telemar-cnf1.v18.lscache6.c.youtube.com%252Fvideoplayback ...);

2. Decode the url (remove the codes %2B,%25 etc), create a decoder with the codes: http://www.w3schools.com/tags/ref_urlencode.asp and use the function Uri.decode(url) to replace invalid escaped octets;

3. Use the code to download stream:

   URL u = null;
   InputStream is = null;  
   
   try {
       u = new URL(url);
       is = u.openStream(); 
       HttpURLConnection huc = (HttpURLConnection)u.openConnection(); //to know the size of video
       int size = huc.getContentLength();                 
   
       if(huc != null) {
           String fileName = "FILE.mp4";
           String storagePath = Environment.getExternalStorageDirectory().toString();
           File f = new File(storagePath,fileName);
   
           FileOutputStream fos = new FileOutputStream(f);
           byte[] buffer = new byte[1024];
           int len1 = 0;
           if(is != null) {
               while ((len1 = is.read(buffer)) > 0) {
                   fos.write(buffer,0, len1);  
               }
           }
           if(fos != null) {
               fos.close();
           }
       }                       
   } catch (MalformedURLException mue) {
       mue.printStackTrace();
   } catch (IOException ioe) {
       ioe.printStackTrace();
   } finally {
       try {               
           if(is != null) {
               is.close();
           }
       } catch (IOException ioe) {
           // just going to ignore this one
       }
   }
   

That's all, most of stuff you'll find on the web!!!

Editor warning: This solution is computationally inefficient and may bring down your connection for a large table.

NB - You need to do this first on a test copy of your table!

When I did it, I found that unless I also included AND n1.id <> n2.id, it deleted every row in the table.

1. If you want to keep the row with the lowest id value:

   DELETE n1 FROM names n1, names n2 WHERE n1.id > n2.id AND n1.name = n2.name
   

2. If you want to keep the row with the highest id value:

   DELETE n1 FROM names n1, names n2 WHERE n1.id < n2.id AND n1.name = n2.name
   

I used this method in MySQL 5.1

Not sure about other versions.

Update: Since people Googling for removing duplicates end up here
Although the OP's question is about DELETE, please be advised that using INSERT and DISTINCT is much faster. For a database with 8 million rows, the below query took 13 minutes, while using DELETE, it took more than 2 hours and yet didn't complete.

INSERT INTO tempTableName(cellId,attributeId,entityRowId,value)
    SELECT DISTINCT cellId,attributeId,entityRowId,value
    FROM tableName;

I ran into this error when running Jest tests. One of the components was being mocked in the setup file, so when I attempted to use the actual component in a test, I was getting very unexpected results.

jest.mock("components/MyComponent", () => ({ children }) => children);

Removing this mock (which wasn't actually needed) fixed my issue immediately.

Perhaps this will save you a few hours of research when you know you're returning from your component correctly.

When in the onclick attribute you do not need to specify that it is Javascript.

<button type="button" 
        onclick="window.open('', '_self', ''); window.close();">Discard</button>

This should do it. In order to close it your page needs to be opened by the script, hence the window.open. Here is an article explaining this in detail:

Click Here

If all else fails, you should also add a message asking the user to manually close the window, as there is no cross-browser solution for this, especially with older browsers such as IE 8.

Capture the onContextMenu event, and return false in the event handler.

You can also capture the click event and check which mouse button fired the event with event.button, in some browsers anyway.

thanks for the help, I've solved my problem :) Here is the code if anyone else needs it :D

import java.util.*;

public class HelloWorld {


public static void main(String[] Args) {

Map<Integer,List<Integer>> map = new HashMap<Integer,List<Integer>>();
List<Integer> list = new ArrayList<Integer>();
list.add(1);
list.add(9);
list.add(11);
map.put(1,list);        

    int First = list.get(1);
    int Second = list.get(2);

    if (First < Second) {

        System.out.println("One or more of your items have been restocked. The current stock is: " + First);

        Random rn = new Random();
int answer = rn.nextInt(99) + 1;

System.out.println("You are buying " + answer + " New stock");

First = First + answer;
list.set(1, First);
System.out.println("There are now " + First + " in stock");
}     
}  
}

when you are using 32bits node on 64bits windows(like node-webkit or atom-shell developers), process.platform will echo win32

use

    function isOSWin64() {
      return process.arch === 'x64' || process.env.hasOwnProperty('PROCESSOR_ARCHITEW6432');
    }

(check here for details)

To send running process to nohup (http://en.wikipedia.org/wiki/Nohup)

nohup -p pid , it did not worked for me

Then I tried the following commands and it worked very fine

1. Run some SOMECOMMAND, say /usr/bin/python /vol/scripts/python_scripts/retention_all_properties.py 1.

2. Ctrl+Z to stop (pause) the program and get back to the shell.

3. bg to run it in the background.

4. disown -h so that the process isn't killed when the terminal closes.

5. Type exit to get out of the shell because now you're good to go as the operation will run in the background in its own process, so it's not tied to a shell.

This process is the equivalent of running nohup SOMECOMMAND.

You can do that I believe. It needs root permission. If you want to know where your apk files are stored, open a emulator and then go to

DDMS>File Explorer-> you can see a directory by name "data" -> Click on it and you will see a "app" folder.

Your apks are stored there. In fact just copying a apk directly to the folder works for me with emulators.

It is possible and sometimes necessary to create the click event along with the element. This is for example when selector based binding is not an option. The key part is to avoid the problem that Tobias was talking about by using .replaceWith() on a single element. Note that this is just a proof of concept.

<script>
    // This simulates the object to handle
    var staticObj = [
        { ID: '1', Name: 'Foo' },
        { ID: '2', Name: 'Foo' },
        { ID: '3', Name: 'Foo' }
    ];
    staticObj[1].children = [
        { ID: 'a', Name: 'Bar' },
        { ID: 'b', Name: 'Bar' },
        { ID: 'c', Name: 'Bar' }
    ];
    staticObj[1].children[1].children = [
        { ID: 'x', Name: 'Baz' },
        { ID: 'y', Name: 'Baz' }
    ];

    // This is the object-to-html-element function handler with recursion
    var handleItem = function( item ) {
        var ul, li = $("<li>" + item.ID + " " + item.Name + "</li>");

        if(typeof item.children !== 'undefined') {
            ul = $("<ul />");
            for (var i = 0; i < item.children.length; i++) {
                ul.append(handleItem(item.children[i]));
            }
            li.append(ul);
        }

        // This click handler actually does work
        li.click(function(e) {
            alert(item.Name);
            e.stopPropagation();
        });
        return li;
    };

    // Wait for the dom instead of an ajax call or whatever
    $(function() {
        var ul = $("<ul />");

        for (var i = 0; i < staticObj.length; i++) {
            ul.append(handleItem(staticObj[i]));
        }

        // Here; this works.
        $('#something').replaceWith(ul);
    });

This helped me to handle Thread was being aborted exception,

try
{
   //Write HTTP output
    HttpContext.Current.Response.Write(Data);
}  
catch (Exception exc) {}
finally {
   try 
    {
      //stop processing the script and return the current result
      HttpContext.Current.Response.End();
     } 
   catch (Exception ex) {} 
   finally {
        //Sends the response buffer
        HttpContext.Current.Response.Flush();
        // Prevents any other content from being sent to the browser
        HttpContext.Current.Response.SuppressContent = true;
        //Directs the thread to finish, bypassing additional processing
        HttpContext.Current.ApplicationInstance.CompleteRequest();
        //Suspends the current thread
        Thread.Sleep(1);
     }
   }

if you use the following the following code instead of HttpContext.Current.Response.End() , you will get Server cannot append header after HTTP headers have been sent exception.

            HttpContext.Current.Response.Flush();
            HttpContext.Current.Response.SuppressContent = True;
            HttpContext.Current.ApplicationInstance.CompleteRequest();

Hope it helps

One solution is to use a background image centered within an element sized to the cropped dimensions.

Basic example

.center-cropped {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  background-position: center center;_x000D_
  background-repeat: no-repeat;_x000D_
}

<div class="center-cropped" _x000D_
     style="background-image: url('http://placehold.it/200x200');">_x000D_
</div>

Example with img tag

This version retains the img tag so that we do not lose the ability to drag or right-click to save the image. Credit to Parker Bennett for the opacity trick.

.center-cropped {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  background-position: center center;_x000D_
  background-repeat: no-repeat;_x000D_
  overflow: hidden;_x000D_
}_x000D_
_x000D_
/* Set the image to fill its parent and make transparent */_x000D_
.center-cropped img {_x000D_
  min-height: 100%;_x000D_
  min-width: 100%;_x000D_
  /* IE 8 */_x000D_
  -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";_x000D_
  /* IE 5-7 */_x000D_
  filter: alpha(opacity=0);_x000D_
  /* modern browsers */_x000D_
  opacity: 0;_x000D_
}

<div class="center-cropped" _x000D_
     style="background-image: url('http://placehold.it/200x200');">_x000D_
  <img src="http://placehold.it/200x200" />_x000D_
</div>

object-fit/-position

See supported browsers.

The CSS3 Images specification defines the object-fit and object-position properties which together allow for greater control over the scale and position of the image content of an img element. With these, it will be possible to achieve the desired effect:

.center-cropped {_x000D_
  object-fit: none; /* Do not scale the image */_x000D_
  object-position: center; /* Center the image within the element */_x000D_
  height: 100px;_x000D_
  width: 100px;_x000D_
}

<img class="center-cropped" src="http://placehold.it/200x200" />

Just run graphics.off() before plotting your data. This instruction solved my error. So, it's harmless to try it before taking a more complex solution.

This worked for me:

File >> Project Structure >> Modules >> Dependency >> + (on left-side of window)

clicking the "+" sign will let you designate the directory where you have unpacked JavaFX's "lib" folder.

Scope is Compile (which is the default.) You can then edit this to call it JavaFX by double-clicking on the line.

then in:

Run >> Edit Configurations

Add this line to VM Options:

--module-path /path/to/JavaFX/lib --add-modules=javafx.controls

(oh and don't forget to set the SDK)

you can use more elements "end" in print:

for iValue in arr:
   print(iValue, end = ", ");

None of these answers worked for me, when all I had was a list of directories. Then I stumbled upon the solution! You have to add -r to --files-from because -a will not be recursive in this scenario (who knew?!).

rsync -aruRP --files-from=directory.list . ../new/location

public string GetName<TSource, TField>(Expression<Func<TSource, TField>> Field)
{
    return (Field.Body as MemberExpression ?? ((UnaryExpression)Field.Body).Operand as MemberExpression).Member.Name;
}

This handles member and unary expressions. The difference being that you will get a UnaryExpression if your expression represents a value type whereas you will get a MemberExpression if your expression represents a reference type. Everything can be cast to an object, but value types must be boxed. This is why the UnaryExpression exists. Reference.

For the sakes of readability (@Jowen), here's an expanded equivalent:

public string GetName<TSource, TField>(Expression<Func<TSource, TField>> Field)
{
    if (object.Equals(Field, null))
    {
        throw new NullReferenceException("Field is required");
    }

    MemberExpression expr = null;

    if (Field.Body is MemberExpression)
    {
        expr = (MemberExpression)Field.Body;
    }
    else if (Field.Body is UnaryExpression)
    {
        expr = (MemberExpression)((UnaryExpression)Field.Body).Operand;
    }
    else
    {
        const string Format = "Expression '{0}' not supported.";
        string message = string.Format(Format, Field);

        throw new ArgumentException(message, "Field");
    }

    return expr.Member.Name;
}

You can use this code for remove subtring and also replace , and also remove extra white space . code :

#include<bits/stdc++.h>
using namespace std ;
void removeSpaces(string &str)
{
   
    int n = str.length();

    int i = 0, j = -1;

    bool spaceFound = false;

    while (++j <= n && str[j] == ' ');

    while (j <= n)
    {
        if (str[j] != ' ')
        {
          
            if ((str[j] == '.' || str[j] == ',' ||
                 str[j] == '?') && i - 1 >= 0 &&
                 str[i - 1] == ' ')
                str[i - 1] = str[j++];

            else
                
                str[i++] = str[j++];

            
            spaceFound = false;
        }
        else if (str[j++] == ' ')
        {
            
            if (!spaceFound)
            {
                str[i++] = ' ';
                spaceFound = true;
            }
        }
    }

    if (i <= 1)
        str.erase(str.begin() + i, str.end());
    else
        str.erase(str.begin() + i - 1, str.end());
}
int main()
{
    string s;
    cin>>s;
    for(int i=s.find("WUB");i>=0;i=s.find("WUB"))
    {
        s.replace(i,3," ");
    }
    removeSpaces(s);
    cout<<s<<endl;

    return 0;
}

on Windows I have python 3.7 installed and I still couldn't activate virtualenv from Gitbash with ./Scripts/activate although it worked from Powershell after running Set-ExecutionPolicy Unrestricted in Powershell and changing the setting to "Yes To All".

I don't like Powershell and I like to use Gitbash, so to activate virtualenv in Gitbash first navigate to your project folder, use ls to list the contents of the folder and be sure you see "Scripts". Change directory to "Scripts" using cd Scripts, once you're in the "Scripts" path use . activate to activate virtualenv. Don't forget the space after the dot.

If you have a valid dtd file for the xml then you can easily transform json to xml and xml to json using the eclipselink jar binary.

Refer this: http://www.cubicrace.com/2015/06/How-to-convert-XML-to-JSON-format.html

The article also has a sample project (including the supporting third party jars) as a zip file which can be downloaded for reference purpose.

You may consider FluentFTP, previously known as System.Net.FtpClient.

It is released under The MIT License and available on NuGet (FluentFTP).

Bit late to the party here, but another way to do it would be to use a Deferred object. You essentially have the same amount of boilerplate, but it's handy if you want to pass them around and possibly resolve outside of their definition.

Naive Implementation:

class Deferred {
  constructor() {
    this.promise = new Promise((resolve, reject)=> {
      this.reject = reject
      this.resolve = resolve
    })
  }
}

function asyncAction() {
  var dfd = new Deferred()

  setTimeout(()=> {
    dfd.resolve(42)
  }, 500)

  return dfd.promise
}

asyncAction().then(result => {
  console.log(result) // 42
})

ES5 Version:

function Deferred() {
  var self = this;
  this.promise = new Promise(function(resolve, reject) {
    self.reject = reject
    self.resolve = resolve
  })
}

function asyncAction() {
  var dfd = new Deferred()

  setTimeout(function() {
    dfd.resolve(42)
  }, 500)

  return dfd.promise
}

asyncAction().then(function(result) {
  console.log(result) // 42
})

This is a solution that has worked well for me.

source /root/miniconda3/etc/profile.d/conda.sh && \
conda activate <your_env> && \
python <your_application> &

I am using miniconda with Conda version 4.7.12 on a Ubuntu 18.04.3 LTS.

I am able to place the above inside a script and run it via crontab as well without any trouble.

Just go to php.ini then find short_open_tag= Off set to short_open_tag= On

Why not just:

IF object_id('YourFunctionName', 'FN') IS NOT NULL
BEGIN
    DROP FUNCTION [dbo].[YourFunctionName]
END
GO

The second argument of object_id is optional, but can help to identify the correct object. There are numerous possible values for this type argument, particularly:

• FN : Scalar function
• IF : Inline table-valued function
• TF : Table-valued-function
• FS : Assembly (CLR) scalar-function
• FT : Assembly (CLR) table-valued function

This worked for me.

Code from the above answer by Dutchie432

.FixedHeightContainer {
    float:right;
    height: 250px;
    width:250px; 
    padding:3px; 
    background:#f00;
}

.Content {
    height:224px;
    overflow:auto;
    background:#fff;
}

Expanding on Adis H's example to include the null case (got bit on this one)

 Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
            if (config.AppSettings.Settings["HostName"] != null)
                config.AppSettings.Settings["HostName"].Value = hostName;
            else                
                config.AppSettings.Settings.Add("HostName", hostName);                
            config.Save(ConfigurationSaveMode.Modified);
            ConfigurationManager.RefreshSection("appSettings");

My guess is that $_.Name does not exist.

If I were you, I'd bring the script into the ISE and run it line for line till you get there then take a look at the value of $_
