Make an jInternalFrame into main frame and make it invisible. Then you can use it for further events.

jInternalFrame.setSize(300,150);
jInternalFrame.setVisible(true);

I needed to template a few files with minimal tooling and for me the issue with above sed -e '/../r file.txt is that it only appends the file after it prints out the rest of the match, it doesn't replace it.

This doesn't do it (all matches are replaced and pattern matching continues from same point)

#!/bin/bash

TEMPDIR=$(mktemp -d "${TMPDIR:-/tmp/}$(basename $0).XXXXXXXXXXXX")
# remove on exit
trap "rm -rf $TEMPDIR" EXIT

DCTEMPLATE=$TEMPDIR/dctemplate.txt
DCTEMPFILE=$TEMPDIR/dctempfile.txt

# template that will replace
printf "0replacement
1${SHELL} data
2anotherlinenoEOL" > $DCTEMPLATE

# test data
echo -e "xxy \n987 \nxx xx\n yz yxxyy" > $DCTEMPFILE

# print original for debug
echo "---8<--- $DCTEMPFILE"
cat $DCTEMPFILE
echo "---8<--- $DCTEMPLATE"
cat $DCTEMPLATE
echo "---8<---"

# replace 'xx' -> contents of $DCTEMPFILE
perl -e "our \$fname = '${DCTEMPLATE}';" -pe 's/xx/`cat $fname`/eg' ${DCTEMPFILE}

Where a is the slice, and i is the index of the element you want to delete:

a = append(a[:i], a[i+1:]...)

... is syntax for variadic arguments in Go.

Basically, when defining a function it puts all the arguments that you pass into one slice of that type. By doing that, you can pass as many arguments as you want (for example, fmt.Println can take as many arguments as you want).

Now, when calling a function, ... does the opposite: it unpacks a slice and passes them as separate arguments to a variadic function.

So what this line does:

a = append(a[:0], a[1:]...)

is essentially:

a = append(a[:0], a[1], a[2])

Now, you may be wondering, why not just do

a = append(a[1:]...)

Well, the function definition of append is

func append(slice []Type, elems ...Type) []Type

So the first argument has to be a slice of the correct type, the second argument is the variadic, so we pass in an empty slice, and then unpack the rest of the slice to fill in the arguments.

Yes, you can use Yarn or NPM to edit your package.json.

yarn upgrade [package | package@tag | package@version | @scope/]... [--ignore-engines] [--pattern]

Something like:

yarn upgrade react@^16.0.0

Then I'd see what warns or errors out and then run yarn upgrade [package]. No need to edit the file manually. Can do everything from the CLI.

Or just run yarn upgrade to update all packages to latest, probably a bad idea for a large project. APIs may change, things may break.

Alternatively, with NPM run npm outdated to see what packages will be affected. Then

npm update

Props can change when a component's parent renders the component again with different properties. I think this is mostly an optimization so that no new component needs to be instantiated.

There's no way to define a playlist using just a <video> or <audio> tag, but there are ways of controlling them, so you can simulate a playlist using JavaScript. Check out sections 4.8.7, 4.8.9 (especially 4.8.9.12) of the HTML5 spec. Hopefully the majority of methods and events are implemented on modern browsers such as Chrome and Firefox (latest versions, of course).

Try using combination of map and lambda functions:

aList = map( lambda x: x, set ([1, 2, 6, 9, 0]) )

It is very convenient approach if you have a set of numbers in string and you want to convert it to list of integers:

aList = map( lambda x: int(x), set (['1', '2', '3', '7', '12']) )

I'm assuming you figured this out already but:

Technical Reference for Log Files in Configuration Manager

That's a list of client-side logs and what they do. They are located in Windows\CCM\Logs

AppEnforce.log will show you the actual command-line executed and the resulting exit code for each Deployment Type (only for the new style ConfigMgr Applications)

This is my go-to for troubleshooting apps. Haven't really found any other logs that are exceedingly useful.

Java 8 Collection has a nice method called removeIf that makes things easier and safer. From the API docs:

default boolean removeIf(Predicate<? super E> filter)
Removes all of the elements of this collection that satisfy the given predicate. 
Errors or runtime exceptions thrown during iteration or by the predicate 
are relayed to the caller.

Interesting note:

The default implementation traverses all elements of the collection using its iterator(). 
Each matching element is removed using Iterator.remove().

From: https://docs.oracle.com/javase/8/docs/api/java/util/Collection.html#removeIf-java.util.function.Predicate-

Sorry, much late to the party, but I'll add here that if you wanted to capture processes with names identical to your search string, you could do

pgrep -x PROCESS_NAME

-x          Require an exact match of the process name, or argument list if -f is given.
             The default is to match any substring.

This is extremely useful if your original process created child processes (possibly zombie when you query) which prefix the original process' name in their own name and you are trying to exclude them from your results. There are many UNIX daemons which do this. My go-to example is ninja-dev-sync.

It seems you have to use is null in the HQL, (which can lead to complex permutations if there are more than one parameters with null potential.) but here is a possible solution:

String statusTerm = status==null ? "is null" : "= :status";
String typeTerm = type==null ? "is null" : "= :type";

Query query = getSession().createQuery("from CountryDTO c where c.status " + statusTerm + "  and c.type " + typeTerm);

if(status!=null){
    query.setParameter("status", status, Hibernate.STRING)
}


if(type!=null){
    query.setParameter("type", type, Hibernate.STRING)
}

import React from 'react';              <--as normal
import PropTypes from 'prop-types';     <--add this as a second line

    App.propTypes = {
        monkey: PropTypes.string,           <--omit "React."
        cat: PropTypes.number.isRequired    <--omit "React."
    };

    Wrong:  React.PropTypes.string
    Right:  PropTypes.string

with the following examples you can use 'IF ELSE'

<p class="{{condition ? 'checkedClass' : 'uncheckedClass'}}">
<p [ngClass]="condition ? 'checkedClass' : 'uncheckedClass'">
<p [ngClass]="[condition ? 'checkedClass' : 'uncheckedClass']">

For any tag one can select all text inside that tag by this short and simple code. It will highlight the entire tag area with yellow colour and select text inside it on single click.

document.onclick = function(event) {
    var range, selection;
event.target.style.backgroundColor = 'yellow';
        selection = window.getSelection();
        range = document.createRange();
        range.selectNodeContents(event.target);
        selection.removeAllRanges();
        selection.addRange(range);
};

Basically, the term "x-bit machine" does not depend on your machine. That is why we do not need to change our processors or other hardware in order to migrate from a 32bit system to a 64bit one (or vice versa).

32bit and 64bit stands for the addressing capability of the OS running on your machine.

However, it still does not mean that a x-bit operating system is capable to address 2^x GB memory. Because the 'B' in "GB" means "byte" and not "bit". 1 byte equals 8 bits.

Actually a 32bit system can not even address 2^32/8 = 2^29 GB memory space while there should some memory be reserved to the OS.

It is something just below 3 GB.

A good reference for finding any symbol in LaTeX is http://detexify.kirelabs.org/classify.html - just draw what you want to find, and it will show you a list of potential symbols.

I want to extend MattMitchell's answer by saying you can create an extension method for this functionality:

public static IsEmptyOrWhitespace(this string value) {
    return String.IsEmptyOrWhitespace(value);
}

This makes it possible to call:

string strValue;
if (strValue.IsEmptyOrWhitespace())
     // do stuff

To me this is a lot cleaner than calling the static String function, while still being NullReference safe!

If you use Angular 6 we can put body in http.request method.

Reference from github

You can try this, for me it works.

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss'],
})
export class AppComponent {

  constructor(
    private http: HttpClient
  ) {
    http.request('delete', url, {body: body}).subscribe();
  }
}

I tried re-creating this, and .someclass.notip was being generated for me but .someclass:not(.notip) was not, for as long as I did not have the @mixin tip() defined. Once I had that, it all worked.

http://sassmeister.com/gist/9775949

$dropdown-width: 100px;
$comp-tip: true;

@mixin tip($pos:right) {

}

@mixin dropdown-pos($pos:right) {
  &:not(.notip) {
    @if $comp-tip == true{
      @if $pos == right {
        top:$dropdown-width * -0.6;
        background-color: #f00;
        @include tip($pos:$pos);
      }
    }
  }
  &.notip {
    @if $pos == right {
      top: 0;
      left:$dropdown-width * 0.8;
      background-color: #00f;
    }
  }
}

.someclass { @include dropdown-pos(); }

EDIT: http://sassmeister.com/ is a good place to debug your SASS because it gives you error messages. Undefined mixin 'tip'. it what I get when I remove @mixin tip($pos:right) { }

Try adding wmode, it seems to have two parameters.

&wmode=Opaque

&wmode=transparent

I can't find a technical reason why it works, or much more explanation but take at look at this query.

<iframe title="YouTube video player" width="480" height="390" src="http://www.youtube.com/embed/lzQgAR_J1PI?wmode=transparent" frameborder="0" wmode="Opaque">

or this

//Fix z-index youtube video embedding
$(document).ready(function (){
    $('iframe').each(function(){
        var url = $(this).attr("src");
        $(this).attr("src",url+"?wmode=transparent");
    });
});

Windows 10 build 15063 "Creators Update" natively supports SVG images (though with some gotchas) to UWP/UAP applications targeting Windows 10.

If your application is a WPF app rather than a UWP/UAP, you can still use this API (after jumping through quite a number of hoops): Windows 10 build 17763 "October 2018 Update" introduced the concept of XAML islands (as a "preview" technology but I believe allowed in the app store; in all cases, with Windows 10 build 18362 "May 2019 Update" XAML islands are no longer a preview feature and are fully supported) allowing you to use UWP APIs and controls in your WPF applications.

You need to first add the references to the WinRT APIs, and to use certain Windows 10 APIs that interact with user data or the system (e.g. loading images from disk in a Windows 10 UWP webview or using the toast notification API to show toasts), you also need to associate your WPF application with a package identity, as shown here (immensely easier in Visual Studio 2019). This shouldn't be necessary to use the Windows.UI.Xaml.Media.Imaging.SvgImageSource class, though.

Usage (if you're on UWP or you've followed the directions above and added XAML island support under WPF) is as simple as setting the Source for an <Image /> to the path to the SVG. That is equivalent to using SvgImageSource, as follows:

<Image>
    <Image.Source>
        <SvgImageSource UriSource="Assets/svg/icon.svg" />
    </Image.Source>
</Image>

However, SVG images loaded in this way (via XAML) may load jagged/aliased. One workaround is to specify a RasterizePixelHeight or RasterizePixelWidth value that is double+ your actual height/width:

<SvgImageSource RasterizePixelHeight="300" RasterizePixelWidth="300" UriSource="Assets/svg/icon.svg" /> <!-- presuming actual height or width is under 150 -->

This can be worked around dynamically by creating a new SvgImageSource in the ImageOpened event for the base image:

var svgSource = new SvgImageSource(new Uri("ms-appx://" + Icon));
PrayerIcon.ImageOpened += (s, e) =>
{
    var newSource = new SvgImageSource(svgSource.UriSource);
    newSource.RasterizePixelHeight = PrayerIcon.DesiredSize.Height * 2;
    newSource.RasterizePixelWidth = PrayerIcon.DesiredSize.Width * 2;
    PrayerIcon2.Source = newSource;
};
PrayerIcon.Source = svgSource;

The aliasing may be hard to see on non high-dpi screens, but here's an attempt to illustrate it.

This is the result of the code above: an Image that uses the initial SvgImageSource, and a second Image below it that uses the SvgImageSource created in the ImageOpened event:

This is a blown up view of the top image:

Whereas this is a blown-up view of the bottom (antialiased, correct) image:

(you'll need to open the images in a new tab and view at full size to appreciate the difference)

cp -rv `ls -A | grep -vE "dirToExclude|targetDir"` targetDir

Edit: forgot to exclude the target path as well (otherwise it would recursively copy).

In his book "CLR Via C#", Jeff Ritcher discourages using System.Timers.Timer, this timer is derived from System.ComponentModel.Component, allowing it to be used in design surface of Visual Studio. So that it would be only useful if you want a timer on a design surface.

He prefers to use System.Threading.Timer for background tasks on a thread pool thread.

Regarding Johannes Schaub's answer:

for(std::vector<T*>::iterator it = v.begin(); it != v.end(); ++it) { 
...
}

That may work with some compilers but not with gcc. The problem here is the question if std::vector::iterator is a type, a variable (member) or a function (method). We get the following error with gcc:

In member function ‘void MyClass<T>::myMethod()’:
error: expected `;' before ‘it’
error: ‘it’ was not declared in this scope
In member function ‘void MyClass<T>::sort() [with T = MyClass]’:
instantiated from ‘void MyClass<T>::run() [with T = MyClass]’
instantiated from here
dependent-name ‘std::vector<T*,std::allocator<T*> >::iterator’ is parsed as a non-type, but instantiation yields a type
note: say ‘typename std::vector<T*,std::allocator<T*> >::iterator’ if a type is meant

The solution is using the keyword 'typename' as told:

typename std::vector<T*>::iterator it = v.begin();
for( ; it != v.end(); ++it) {
...

I think I have found the cleanest way to program in JavaScript, but you'll need some imagination. I got this idea from a working technique in the book JavaScript: The Good Parts.

Instead of using the new keyword, you could create a class like this:

function Class()
{
    var obj = {}; // Could also be used for inheritance if you don't start with an empty object.

    var privateVar;
    obj.publicVar;

    obj.publicMethod = publicMethod;
    function publicMethod(){}

    function privateMethod(){}

    return obj;
}

You can instantiate the above object by saying:

var objInst = Class(); // !!! NO NEW KEYWORD

Now with this work method in mind, you could create a singleton like this:

ClassSingleton = function()
{
    var instance = null;

    function Class() // This is the class like the above one
    {
        var obj = {};
        return obj;
    }

    function getInstance()
    {
        if( !instance )
            instance = Class(); // Again no 'new' keyword;

        return instance;
    }

    return { getInstance : getInstance };
}();

Now you can get your instance by calling

var obj = ClassSingleton.getInstance();

I think this is the neatest way as the complete "Class" is not even accessible.

Without jQuery:

document.getElementById('file').onchange = function(){

  var file = this.files[0];

  var reader = new FileReader();
  reader.onload = function(progressEvent){
    // Entire file
    console.log(this.result);

    // By lines
    var lines = this.result.split('\n');
    for(var line = 0; line < lines.length; line++){
      console.log(lines[line]);
    }
  };
  reader.readAsText(file);
};

HTML:

<input type="file" name="file" id="file">

Remember to put your javascript code after the file field is rendered.

npm install --silent

Seems to suppress the funding issue.

Try

git diff k73ud^..dj374

to make sure to include all changes of k73ud in the resulting diff.

git diff compares two endpoints (instead of a commit range). Since the OP want to see the changes introduced by k73ud, he/she needs to difference between the first parent commit of k73ud: k73ud^ (or k73ud^1 or k73ud~).

That way, the diff results will include changes since k73ud parent (meaning including changes from k73ud itself), instead of changes introduced since k73ud (up to dj374).

Also you can try:

git diff oldCommit..newCommit
git diff k73ud..dj374 

and (1 space, not more):

git diff oldCommit newCommit
git diff k73ud dj374

And if you need to get only files names (e.g. to copy hotfix them manually):

git diff k73ud dj374 --name-only

And you can get changes applied to another branch:

git diff k73ud dj374 > my.patch
git apply my.patch

At this moment, PHP itself does not provide a way to get the project's root directory for sure.

But you can implement a very simple method yourself that will do exactly what you're looking for.

Solution

Create a new file in your project, let say D:/workspace/MySystem/Code/FilesManager.php (use whatever name and path suit you the best). Then, use the following code:

<?php

class FilesManager
{
  public static function rootDirectory()
  {
    // Change the second parameter to suit your needs
    return dirname(__FILE__, 2);
  }
}

Now you can do this in, let's say D:/workspace/MySystem/Code/a/b/c/Feature.php:

echo FilesManager::rootDirectory();

And the expected result should be:

"D:/workspace/MySystem"

The output will be the same no matter where your "feature" file is located in the project.

Explanation

dirname is used to return the parent directory of the first parameter. We use the magic constant __FILE__ to give it FilesManager.php's path. The second parameter tells how many times to go up in the hierarchy. In this case, we need to do it twice, but it really depends where you put your file in the hierarchy. You can omit the second parameter if you only need to got up once, meaning the file is located in the root. But then, you can return __DIR__ directly instead.

This solution is guaranteed to work, no matter where the root is located on your server. Unless you end up moving the utility class somewhere else in the hierarchy.

Additional note

I'd avoid using DOCUMENT_ROOT for the following reasons (according to this answer):

• It makes your application dependent on the server.
• The Apache setup may give an incorrect path to the root directory.

Concrete example

mosquitto.org is very active (at the time of this posting). This is a nice smoke test for a MQTT subscriber linux device:

mosquitto_sub -h test.mosquitto.org -t "#" -v

The "#" is a wildcard for topics and returns all messages (topics): the server had a lot of traffic, so it returned a 'firehose' of messages.

If your MQTT device publishes a topic of irisys/V4D-19230005/ to the test MQTT broker , then you could filter the messages:

mosquitto_sub -h test.mosquitto.org -t "irisys/V4D-19230005/#" -v

Options:

• -h the hostname (default MQTT port = 1883)
• -t precedes the topic

I personally favour this syntax, which uses the explicit IsDbNull method exposed by IDataRecord, and caches the column index to avoid a duplicate string lookup.

Expanded for readability, it goes something like:

int columnIndex = row.GetOrdinal("Foo");
string foo; // the variable we're assigning based on the column value.
if (row.IsDBNull(columnIndex)) {
  foo = String.Empty; // or whatever
} else { 
  foo = row.GetString(columnIndex);
}

Rewritten to fit on a single line for compactness in DAL code - note that in this example we're assigning int bar = -1 if row["Bar"] is null.

int i; // can be reused for every field.
string foo  = (row.IsDBNull(i  = row.GetOrdinal("Foo")) ? null : row.GetString(i));
int bar = (row.IsDbNull(i = row.GetOrdinal("Bar")) ? -1 : row.GetInt32(i));

The inline assignment can be confusing if you don't know it's there, but it keeps the entire operation on one line, which I think enhances readability when you're populating properties from multiple columns in one block of code.

This will give you the result you're giving as an example:

SELECT DISTINCT a, b
FROM pairs

Array notation and pointer arithmetic can be used interchangeably in C/C++ (this is not true for ALL the cases but by the time you get there, you will find the cases yourself). So although str is a pointer, you can use it as if it were an array like so:

char char_E = str[1];
char char_L1 = str[2];
char char_O = str[4];

...and so on. What you could also do is "add" 1 to the value of the pointer to a character str which will then point to the second character in the string. Then you can simply do:

str = str + 1; // makes it point to 'E' now
char myChar =  *str;

I hope this helps.

The syntax for crontab

* * * * * 

Minute(0-59) Hour(0-24) Day_of_month(1-31) Month(1-12) Day_of_week(0-6) Command_to_execute

Your syntax

* 22 * * * test > /dev/null

your job will Execute every minute at 22:00 hrs all week, month and year.

adding an option (0-59) at the minute place will run it once at 22:00 hrs all week, month and year.

0 22 * * * command_to_execute 

Source https://www.adminschoice.com/crontab-quick-reference

as long as you did not commit you can type

git merge --abort

just as the command line suggested.

You must build parent module before doing child module.

Also, starting with .NET Core 3.0 (and .NET Standard 2.1) (C# 8) you can use Index type to keep array's indexes from end:

var lastElementIndexInAnyArraySize = ^1;
var lastElement = array[lastElementIndexInAnyArraySize];

You can use this index to get last array value in any lenght of array. For example:

var firstArray = new[] {0, 1, 1, 2, 2};
var secondArray = new[] {3, 3, 4, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5};
var index = ^1;
var firstArrayLastValue = firstArray[index]; // 2
var secondArrayLastValue = secondArray[index]; // 5

First, get the intent which has started your activity using the getIntent() method:

Intent intent = getIntent();

If your extra data is represented as strings, then you can use intent.getStringExtra(String name) method. In your case:

String id = intent.getStringExtra("id");
String name = intent.getStringExtra("name");

SELECT
main.CustomerID,
f.Data AS FirstName,
m.Data AS MiddleName,
l.Data AS LastName,
d.Data AS Date
FROM table main
INNER JOIN table f on f.CustomerID = main.CustomerID
INNER JOIN table m on m.CustomerID = main.CustomerID
INNER JOIN table l on l.CustomerID = main.CustomerID
INNER JOIN table d on d.CustomerID = main.CustomerID
WHERE f.DBColumnName = 'FirstName' 
AND m.DBColumnName = 'MiddleName' 
AND l.DBColumnName = 'LastName' 
AND d.DBColumnName = 'Date' 

Edit: I have written this without an editor & have not run the SQL. I hope, you get the idea.

You can make an AJAX request like any other requests:

As I wrote in the edits of the op, to edit existing excel documents you must use the xlutils module (Thanks Oliver)

Here is the proper way to do it:

#xlrd, xlutils and xlwt modules need to be installed.  
#Can be done via pip install <module>
from xlrd import open_workbook
from xlutils.copy import copy

rb = open_workbook("names.xls")
wb = copy(rb)

s = wb.get_sheet(0)
s.write(0,0,'A1')
wb.save('names.xls')

This replaces the contents of the cell located at a1 in the first sheet of "names.xls" with the text "a1", and then saves the document.

I know this is not an ideal question to answer but as the OP seems to be a beginner, I'd love to share some basic knowledge with him... Hope everybody understands

OP, you can convert a string to type Boolean by using any of the methods stated below:

 string sample = "True";
 bool myBool = bool.Parse(sample);

 ///or

 bool myBool = Convert.ToBoolean(sample);

bool.Parse expects one parameter which in this case is sample, .ToBoolean also expects one parameter.

You can use TryParse which is the same as Parse but it doesn't throw any exception :)

  string sample = "false";
  Boolean myBool;

  if (Boolean.TryParse(sample , out myBool))
  {
  }

Please note that you cannot convert any type of string to type Boolean because the value of a Boolean can only be True or False

Hope you understand :)

Straight from documentation http://getbootstrap.com/css/#forms-horizontal.

Use Bootstrap's predefined grid classes to align labels and groups of form controls in a horizontal layout by adding .form-horizontal to the form (which doesn't have to be a <form>). Doing so changes .form-groups to behave as grid rows, so no need for .row.

Sample:

<form class="form-horizontal">
  <div class="form-group">
    <label for="inputEmail3" class="col-sm-2 control-label">Email</label>
    <div class="col-sm-10">
      <input type="email" class="form-control" id="inputEmail3" placeholder="Email">
    </div>
  </div>
  <div class="form-group">
    <label for="inputPassword3" class="col-sm-2 control-label">Password</label>
    <div class="col-sm-10">
      <input type="password" class="form-control" id="inputPassword3" placeholder="Password">
    </div>
  </div>
  <div class="form-group">
    <div class="col-sm-offset-2 col-sm-10">
      <div class="checkbox">
        <label>
          <input type="checkbox"> Remember me
        </label>
      </div>
    </div>
  </div>
  <div class="form-group">
    <div class="col-sm-offset-2 col-sm-10">
      <button type="submit" class="btn btn-default">Sign in</button>
    </div>
  </div>
</form>

set scrolling="no" attribute in your iframe.

I can reproduce your problem if there are no files in the directory that were modified in the last hour. In that case, find . -mmin -60 returns nothing. The command find . -mmin -60 |xargs ls -l, however, returns every file in the directory which is consistent with what happens when ls -l is run without an argument.

To make sure that ls -l is only run when a file is found, try:

find . -mmin -60 -type f -exec ls -l {} +

You can use 'onclick' attribute like this :

<a ... href="javascript: onclick();" ...>...</a>

I wanted to share a solution I came up with using jQuery that works if you have multiple YouTube videos embedded on a single page. In my case, I have defined a modal popup for each video as follows:

<div id="videoModalXX">
...
    <button onclick="stopVideo(videoID);" type="button" class="close"></button>
    ...
    <iframe width="90%" height="400" src="//www.youtube-nocookie.com/embed/video_id?rel=0&enablejsapi=1&version=3" frameborder="0" allowfullscreen></iframe>
...
</div>

In this case, videoModalXX represents a unique id for the video. Then, the following function stops the video:

function stopVideo(id)
{
    $("#videoModal" + id + " iframe")[0].contentWindow.postMessage('{"event":"command","func":"pauseVideo","args":""}', '*');
}

I like this approach because it keeps the video paused where you left off in case you want to go back and continue watching later. It works well for me because it's looking for the iframe inside of the video modal with a specific id. No special YouTube element ID is required. Hopefully, someone will find this useful as well.

You can parse the text as a string, which creates an Element, and create an ElementTree using that Element.

import xml.etree.ElementTree as ET
tree = ET.ElementTree(ET.fromstring(xmlstring))

I just came across this issue and the documentation, while complete, is not very straightforward on the difference in usage between the parse() and fromstring() methods.

To my knowledge, Ejabberd (http://www.ejabberd.im/) is the parent, this is XMPP server which provide quite good features of open source, Whatsapp uses some modified version of this, facebook messaging also uses a modified version of this. Some more chat applications likes Samsung's ChatOn, Nimbuzz messenger all use ejabberd based ones and Erlang solutions also have modified version of this ejabberd which they claim to be highly scalable and well tested with more performance improvements and renamed as MongooseIM.

Ejabberd is the server which has most of the featured implemented when compared to other. Since it is build in Erlang it is highly scalable horizontally.

No need for a custom class. This is all that is needed:

return new JsonResult { Data = Result, MaxJsonLength = Int32.MaxValue };

where Result is that data you wish to serialize.

Another choice besides JObject is System.Json.JsonValue for Weak-Typed JSON object.

It also has a JsonValue blob = JsonValue.Parse(json); you can use. The blob will most likely be of type JsonObject which is derived from JsonValue, but could be JsonArray. Check the blob.JsonType if you need to know.

And to answer you question, YES, you may replace json with the name of your actual variable that holds the JSON string. ;-D

There is a System.Json.dll you should add to your project References.

Regardless to Your example

select length('Burger') from dual;

I hope this will help :)

As of .NET 5 RC2 you can use:

• Convert.ToHexString(byte[] inArray) which returns a string and
• Convert.FromHexString(string s) which returns a byte[].

Overloads are available that take span parameters.

Assuming that the order is the same in both objects, just stringify them both and compare!

JSON.stringify(obj1) == JSON.stringify(obj2);

From the announcement Git 1.7.10 (April 2012):

• git clone learned --single-branch option to limit cloning to a single branch (surprise!); tags that do not point into the history of the branch are not fetched.

Git actually allows you to clone only one branch, for example:

git clone -b mybranch --single-branch git://sub.domain.com/repo.git

Note: Also you can add another single branch or "undo" this action.

This can happen with symlinks sometimes. If you experience this issue and you know you are in an existing directory, but your symlink may have changed, you can use this command:

cd $(pwd)

The two calls have different meanings that have nothing to do with performance; the fact that it speeds up the execution time is (or might be) just a side effect. You should understand what each of them does and not blindly include them in every program because they look like an optimization.

ios_base::sync_with_stdio(false);

This disables the synchronization between the C and C++ standard streams. By default, all standard streams are synchronized, which in practice allows you to mix C- and C++-style I/O and get sensible and expected results. If you disable the synchronization, then C++ streams are allowed to have their own independent buffers, which makes mixing C- and C++-style I/O an adventure.

Also keep in mind that synchronized C++ streams are thread-safe (output from different threads may interleave, but you get no data races).

cin.tie(NULL);

This unties cin from cout. Tied streams ensure that one stream is flushed automatically before each I/O operation on the other stream.

By default cin is tied to cout to ensure a sensible user interaction. For example:

std::cout << "Enter name:";
std::cin >> name;

If cin and cout are tied, you can expect the output to be flushed (i.e., visible on the console) before the program prompts input from the user. If you untie the streams, the program might block waiting for the user to enter their name but the "Enter name" message is not yet visible (because cout is buffered by default, output is flushed/displayed on the console only on demand or when the buffer is full).

So if you untie cin from cout, you must make sure to flush cout manually every time you want to display something before expecting input on cin.

In conclusion, know what each of them does, understand the consequences, and then decide if you really want or need the possible side effect of speed improvement.

Good old readline();.

See MDN (archive).

It's fine to manually select each number for a small set of numbers like in your example, but for larger collections you can do a regex search which will do the work for you.

Ctrl + F will open the search bar.

Regex searches are enabled by clicking the ".*" button on the far left.

Type in "\d+" to search for all occurrences of 1 or more digits. Clicking the "Find All" button will select each of these numbers separately.

Then you can use Ctrl + Shift + L to convert the selection into multiple cursors. From here you can do as you like.

I had Python 2.7 and wanted to be able to switch to Python 3 inside of Jupyter.

These steps worked for me on a Windows Anaconda Command Prompt:

conda update conda
conda create -n py33 python=3.3 anaconda
activate py33
ipython kernelspec install-self
deactivate

Now after opening ipython notebook with the usual command for Python2.7, Python3.3 is also available when creating a new notebook.

Instead of an arraylist or dictionary you can also use a dynamic. Most of the time I use EasyHttp for this, but sure there will by other projects that do the same. An example below:

var http = new HttpClient();
http.Request.Accept = HttpContentTypes.ApplicationJson;
var response = http.Get("url");
var body = response.DynamicBody;
Console.WriteLine("Name {0}", body.AppName.Description);
Console.WriteLine("Name {0}", body.AppName.Value);

On NuGet: EasyHttp

Installing MongoDB on Windows is a bit tricky compared to other Executable files... Got a good reference after long search I got Installing MongoDB in Windows

After Installing open command prompt and type "mongod", then keep the window minimized and open another command prompt window and type "mongo" and you will find the success message of connecting to the test database.

hope it helps

Update

The Unconstrained Melody library is no longer maintained; Support was dropped in favour of Enums.NET.

In Enums.NET you'd use:

string description = ((MyEnum)value).AsString(EnumFormat.Description);

Original post

I implemented this in a generic, type-safe way in Unconstrained Melody - you'd use:

string description = Enums.GetDescription((MyEnum)value);

This:

• Ensures (with generic type constraints) that the value really is an enum value
• Avoids the boxing in your current solution
• Caches all the descriptions to avoid using reflection on every call
• Has a bunch of other methods, including the ability to parse the value from the description

I realise the core answer was just the cast from an int to MyEnum, but if you're doing a lot of enum work it's worth thinking about using Unconstrained Melody :)

Try using display() function. This would automatically use Horizontal and vertical scroll bars and with this you can display different datasets easily instead of using print().

display(dataframe)

display() supports proper alignment also.

However if you want to make the dataset more beautiful you can check pd.option_context(). It has lot of options to clearly show the dataframe.

Note - I am using Jupyter Notebooks.

it saves your .bat file to "Appdata of current user" ,if it does not exist and remove the attributes and after that set the "hidden" attributes to file after writing your cmd code and run it silently and capture all output saves it to file so if u wanna save all output of cmd to file just add your like this

code > C:\Users\Lenovo\Desktop\output.txt

just replace word "code" with your .bat file code or command and after that the directory of output file I found one code recently after searching alot if u wanna run .bat file in vb or c# or simply just add this in the same manner in which i have written

Lets start with 3. That wouldnt work. public getMyProperty() has no return typ.

And number 1 and 2 are actually same things. 2 is what number 1 becomes after compilation.

So 1 and 2 are same things. with two you can have some validation or caching in your model.

other than that they become same.

I have the same error I was replacing my Set with a new one get from Jackson.

To solve this I keep the existing set, I remove from the old set the element unknown into the new list with retainAll. Then I add the new ones with addAll.

    this.oldSet.retainAll(newSet);
    this.oldSet.addAll(newSet);

No need to have the Session and manipulate it.

The Host Header tells the webserver which virtual host to use (if set up). You can even have the same virtual host using several aliases (= domains and wildcard-domains). In this case, you still have the possibility to read that header manually in your web app if you want to provide different behavior based on different domains addressed. This is possible because in your webserver you can (and if I'm not mistaken you must) set up one vhost to be the default host. This default vhost is used whenever the host header does not match any of the configured virtual hosts.

That means: You get it right, although saying "multiple hosts" may be somewhat misleading: The host (the addressed machine) is the same, what really gets resolved to the IP address are different domain names (including subdomains) that are also referred to as hostnames (but not hosts!).

Although not part of the question, a fun fact: This specification led to problems with SSL in early days because the web server has to deliver the certificate that corresponds to the domain the client has addressed. However, in order to know what certificate to use, the webserver should have known the addressed hostname in advance. But because the client sends that information only over the encrypted channel (which means: after the certificate has already been sent), the server had to assume you browsed the default host. That meant one ssl-secured domain per IP address / port-combination.

This has been overcome with Server Name Indication; however, that again breaks some privacy, as the server name is now transferred in plain text again, so every man-in-the-middle would see which hostname you are trying to connect to.

Although the webserver would know the hostname from Server Name Indication, the Host header is not obsolete, because the Server Name Indication information is only used within the TLS handshake. With an unsecured connection, there is no Server Name Indication at all, so the Host header is still valid (and necessary).

Another fun fact: Most webservers (if not all) reject your HTTP request if it does not contain exactly one Host header, even if it could be omitted because there is only the default vhost configured. That means the minimum required information in an http-(get-)request is the first line containing METHOD RESOURCE and PROTOCOL VERSION and at least the Host header, like this:

GET /someresource.html HTTP/1.1
Host: www.example.com

In the MDN Documentation on the "Host" header they actually phrase it like this:

A Host header field must be sent in all HTTP/1.1 request messages. A 400 (Bad Request) status code will be sent to any HTTP/1.1 request message that lacks a Host header field or contains more than one.

As mentioned by Darrel Miller, the complete specs can be found in RFC7230.

localStorage.username = 'blah'

If you're guaranteed to be on a modern browser. Though know your values will all be turned into strings.

Also has the handy benefit of being cached between reloads.

Use a simple Faraday cage to block or limit the external RF signal level.

You can make your own with aluminum foil. The openings should be smaller than the wavelength of your data service if that's what you want to block.

800 Mhz has a 37 cm (14") wavelength, 1900 Mhz has a 16 cm (6") wavelength.

This works better with an actual device than with the simulator since the Mac is hard to work on when inside the Faraday cage ;-)

I worked with Unity and had some problem with the BeginConnect and other async methods from socket.

There is something than I don't understand but the code samples before doesn't work for me.

So I wrote this piece of code to make it work. I test it on an adhoc network with android and pc, also in local on my computer. Hope it can help.

If you just want the first number to match you can do it like this:

[item for item in a if item[0] == 1]

If you are just searching for tuples with 1 in them:

[item for item in a if 1 in item]

you can also use

<br style="clear:both" />

@NotNull is a JSR 303 Bean Validation annotation. It has nothing to do with database constraints itself. As Hibernate is the reference implementation of JSR 303, however, it intelligently picks up on these constraints and translates them into database constraints for you, so you get two for the price of one. @Column(nullable = false) is the JPA way of declaring a column to be not-null. I.e. the former is intended for validation and the latter for indicating database schema details. You're just getting some extra (and welcome!) help from Hibernate on the validation annotations.

To access the first and last elements, try.

var nodes = div.querySelectorAll('[move_id]');
var first = nodes[0];
var last = nodes[nodes.length- 1];

For robustness, add index checks.

Yes, the order of nodes is pre-order depth-first. DOM's document order is defined as,

There is an ordering, document order, defined on all the nodes in the document corresponding to the order in which the first character of the XML representation of each node occurs in the XML representation of the document after expansion of general entities. Thus, the document element node will be the first node. Element nodes occur before their children. Thus, document order orders element nodes in order of the occurrence of their start-tag in the XML (after expansion of entities). The attribute nodes of an element occur after the element and before its children. The relative order of attribute nodes is implementation-dependent.

Of course, if you want to make sure it's in there otherwise fail then this works:

thisTag = _tags[key];

NOTE: This will fail if the key,value pair does not exists but sometimes that is exactly what you want. This way you can catch it and do something about the error. I would only do this if I am certain that the key,value pair is or should be in the dictionary and if not I want it to know about it via the throw.

Both lines have the same problem

T newT1 = "some text";
T newT2 = (string)t;

The compiler doesn't know that T is a string and so has no way of knowing how to assign that. But since you checked you can just force it with

T newT1 = "some text" as T;
T newT2 = t; 

you don't need to cast the t since it's already a string, also need to add the constraint

where T : class

DataFrame['Col_name'].replace("None", np.nan, inplace=True)

Another common error occurs when including a URL which contains an ampersand ("&"):

This is invalid:

a href="foo.cgi?chapter=1&section=2&copy=3&lang=en"

Explanation:

This example generates an error for "unknown entity section" because the "&" is assumed to begin an entity reference. Browsers often recover safely from this kind of error, but real problems do occur in some cases. In this example, many browsers correctly convert &copy=3 to ©=3, which may cause the link to fail. Since ⟨ is the HTML entity for the left-pointing angle bracket, some browsers also convert &lang=en to <=en. And one old browser even finds the entity §, converting &section=2 to §ion=2.

So the goal here is to avoid problems when you are trying to validate your website. So you should be replacing your ampersands with & when writing a URL in your markup.

Note that replacing & with &amp; is only done when writing the URL in HTML, where "&" is a special character (along with "<" and ">"). When writing the same URL in a plain text email message or in the location bar of your browser, you would use "&" and not "&". With HTML, the browser translates "&" to "&" so the Web server would only see "&" and not "&" in the query string of the request.

Hope this helps : )

Building on Terry's simple answer I made this into a basic jQuery function

$.prototype.disableTab = function() {
    this.each(function() {
        $(this).attr('tabindex', '-1');
    });
};

$('.unfocusable-element, .another-unfocusable-element').disableTab();

I had faced the same issue because of some dll files were missing from References of VS13. I went to the location http://scn.sap.com/docs/DOC-7824 and installed the newest pack. It resolved the issue.

The best solution for me was to add a key binding to run PHP code directly in the terminal

To do so you just need to download terminal-command-keys from VS code extensions marketplace:

Then got to File>Preferences>Keyboard Shortcuts and click on the following icon at the upper right corner:

It will open up the keybindings.json file

Add the following settings

[
    {
        "key": "ctrl+s",
        "command":"terminalCommandKeys.run",
        "when": "editorLangId == php",
        "args": {
            "cmd":"php ${file}",
            "newTerminal":true,
            "saveAllfiles": true,
            "showTerminal": true,
        }
    }
]

key is the shortcut to run your PHP file (I use ctrl+s) you can change it as you wish

when to run different commands for different file types (I set it for PHP files only) vscode's "when" clauses

See the full settings documentation from here

That's it, I hope it helps.

Personally, I think the concatenation is the better solution. The generic implementation would be

entity shifter is
    generic (
        REGSIZE  : integer := 8);
    port(
        clk      : in  str_logic;
        Data_in  : in  std_logic;
        Data_out : out std_logic(REGSIZE-1 downto 0);
end shifter ;

architecture bhv of shifter is
    signal shift_reg : std_logic_vector(REGSIZE-1 downto 0) := (others<='0');
begin
    process (clk) begin
        if rising_edge(clk) then
            shift_reg <= shift_reg(REGSIZE-2 downto 0) & Data_in;
        end if;
    end process;
end bhv;
Data_out <= shift_reg;

Both will implement as shift registers. If you find yourself in need of more shift registers than you are willing to spend resources on (EG dividing 1000 numbers by 4) you might consider using a BRAM to store the values and a single shift register to contain "indices" that result in the correct shift of all the numbers.

If you add the extension .SH to the environment variable PATHEXT, you will be able to run shell scripts from PowerShell by only using the script name with arguments:

PS> .\script.sh args

If you store your scripts in a directory that is included in your PATH environment variable, you can run it from anywhere, and omit the extension and path:

PS> script args

Note: sh.exe or another *nix shell must be associated with the .sh extension.

In Windows, with GetFileInformationByHandleEx, passing FileNameInfo, you can retrieve the file name.

//file1.php
<?php

class ClassA
{
   private $name = 'John';

   function getName()
   {
     return $this->name;
   }   
}
?>

//file2.php
<?php
   include ("file1.php");

   class ClassB
   {

     function __construct()
     {
     }

     function callA()
     {
       $classA = new ClassA();
       $name = $classA->getName();
       echo $name;    //Prints John
     }
   }

   $classb = new ClassB();
   $classb->callA();
?>

This is not an answer to the original question. But, as an original question is not a real-world problem it should not be a problem. I tried to explain to a friend what are promises in JavaScript and the difference between promise and callback.

Code below serves as an explanation:

//very basic callback example using setTimeout
//function a is asynchronous function
//function b used as a callback
function a (callback){
    setTimeout (function(){
       console.log ('using callback:'); 
       let mockResponseData = '{"data": "something for callback"}'; 
       if (callback){
          callback (mockResponseData);
       }
    }, 2000);

} 

function b (dataJson) {
   let dataObject = JSON.parse (dataJson);
   console.log (dataObject.data);   
}

a (b);

//rewriting above code using Promise
//function c is asynchronous function
function c () {
   return new Promise(function (resolve, reject) {
     setTimeout (function(){
       console.log ('using promise:'); 
       let mockResponseData = '{"data": "something for promise"}'; 
       resolve(mockResponseData); 
    }, 2000);      
   }); 

}

c().then (b);

JsFiddle

Assuming that your branch was created off of master, then while in the branch (that is, you have the branch checked out):

git cherry -v master

or

git log master..

If you are not in the branch, then you can add the branch name to the "git log" command, like this:

git log master..branchname

If your branch was made off of origin/master, then say origin/master instead of master.

We don't know what server.properties file is that, we neither know what SimocoPoolSize means (do you?)

Let's guess you are using some custom pool of database connections. Then, I guess the problem is that your pool is configured to open 100 or 120 connections, but you Postgresql server is configured to accept MaxConnections=90 . These seem conflictive settings. Try increasing MaxConnections=120.

But you should first understand your db layer infrastructure, know what pool are you using, if you really need so many open connections in the pool. And, specially, if you are gracefully returning the opened connections to the pool

In Android

Android has a built in class for managing URIs.

Uri uri = Uri.parse("http://base_path/some_segment/id");
String lastPathSegment = uri.getLastPathSegment()

This should work fine (using .text():

$("#toptitle").text("New word");

fixed position is a bit tricky (indeed impossible), but position: sticky is doing the trick beautifully:

<div class='container'>
  <header>This is the header</header>
  <section>
    ... long lorem ipsum
  </section>
</div>

body {
  text-align: center;  
}

.container {
  text-align: left;
  max-width: 30%;
  margin: 0 auto;
}


header {
  line-height: 2rem;
  outline: 1px solid red;
  background: #fff;
  padding: 1rem;

  position: sticky;
  top: 0;
}

You're thinking too complicated. It's actually just $('#'+openaddress).

Try this:

find . -name "*.pdf" -type f -exec cp {} ./pdfsfolder \;

Going Relative:

• You could download a self-contained directory (maybe a zipped file) and open links from an html or xml locally without need to reach the server. This increases speed performance significantly, specially if you have to deal with a slow network.

Going Absolute:

• You would have to swallow the network speed, but in terms of security you could prevent certain users to see certain files or increase network traffic if (and only if...) that is good for you.

sed -i -- "s/https/http/g" file.txt

As was in my case if your sql is generated by concatenating or uses converts then sql at execute need to be prefixed with letter N as below

e.g.

Exec N'Select bla..' 

the N defines string literal is unicode.

It is a library from SSL. You need to install openssl.

You might also meet missing readline() function in python. You have to install pyreadline Lib.

You could simply not include the line into the new file instead of doing replace.

for line in infile :
     if 'bad' not in line and 'naughty' not in line:
            newopen.write(line)

var formatter = new Intl.NumberFormat("ru", {
  style: "currency",
  currency: "GBP"
});

alert( formatter.format(1234.5) ); // 1 234,5 £

Yes: call the toPandas method on your dataframe and you'll get an actual pandas dataframe !

That error arises when you try to encode a non-unicode string: it tries to decode it, assuming it's in plain ASCII. There are two possibilities:

1. You're encoding it to a bytestring, but because you've used codecs.open, the write method expects a unicode object. So you encode it, and it tries to decode it again. Try: f.write(all_html) instead.
2. all_html is not, in fact, a unicode object. When you do .encode(...), it first tries to decode it.

Whilst, as has been pointed out, it is possible to see the current default socket buffer sizes in /proc, it is also possible to check them using sysctl (Note: Whilst the name includes ipv4 these sizes also apply to ipv6 sockets - the ipv6 tcp_v6_init_sock() code just calls the ipv4 tcp_init_sock() function):

 sysctl net.ipv4.tcp_rmem
 sysctl net.ipv4.tcp_wmem

However, the default socket buffers are just set when the sock is initialised but the kernel then dynamically sizes them (unless set using setsockopt() with SO_SNDBUF). The actual size of the buffers for currently open sockets may be inspected using the ss command (part of the iproute package), which can also provide a bunch more info on sockets like congestion control parameter etc. E.g. To list the currently open TCP (t option) sockets and associated memory (m) information:

ss -tm

Here's some example output:

State       Recv-Q Send-Q        Local Address:Port        Peer Address:Port

skmem:(r0,rb369280,t0,tb87040,f0,w0,o0,bl0,d0)

Here's a brief explanation of skmem (socket memory) - for more info you'll need to look at the kernel sources (e.g. sock.h):

r:sk_rmem_alloc
rb:sk_rcvbuf          # current receive buffer size
t:sk_wmem_alloc
tb:sk_sndbuf          # current transmit buffer size
f:sk_forward_alloc
w:sk_wmem_queued      # persistent transmit queue size
o:sk_omem_alloc
bl:sk_backlog
d:sk_drops

Since the OP has mentioned he does not have access to the base class inside of which exists a HashMap - I am afraid there are very few options available.

One (painfully slow and resource intensive) way of performing a deep copy of an object in Java is to abuse the 'Serializable' interface which many classes either intentionally - or unintentionally extend - and then utilise this to serialise your class to ByteStream. Upon de-serialisation you will have a deep copy of the object in question.

A guide for this can be found here: https://www.avajava.com/tutorials/lessons/how-do-i-perform-a-deep-clone-using-serializable.html

SELECT *

If you need add group by clause. If you search Smith you would have to sort on something else.

Here is the solution, that I adopted as a combination of some proposed solutions in some other forums.

This way you can reference both css files and other js files in one js file, thus making change next time only in a single place. Please let me know if you have any concerns on it.

I have done following:

1. I have created a js with name jQueryIncluder.js

2. declared and executed following code in this file

   function getVirtualDirectory() {
     var vDir = document.location.pathname.split('/');
     return '/' + vDir[1] + '/';
   }
   
   function include_jQueryFilesToPage() {
     var siteAddress = location.protocol + '//' + document.location.hostname + getVirtualDirectory(); 
     var jqCSSFilePath =  siteAddress + 'includes/jQueryCSS/ehrgreen-theme/jquery-ui-1.8.2.custom.css';
     var jqCoreFilePath = siteAddress + 'includes/jquery-1.4.1.min.js';
     var jqUIFilePath =   siteAddress + 'includes/jquery-ui-1.8.2.custom.min.js';
     var head  = document.getElementsByTagName('head')[0]; 
   
     // jQuery CSS jnclude
     var jqCSS = 'cssIDJQ';  // you could encode the css path itself to generate id.
     if (!document.getElementById(jqCSS)) { 
       var link  = document.createElement('link'); 
       link.id  = jqCSS; 
       link.rel  = 'stylesheet'; 
       link.type = 'text/css'; 
       link.href = jqCSSFilePath; 
       link.media = 'all'; 
       head.appendChild(link); 
     } 
   
     // Core jQuery include
     var jqc = "coreFileRefIDJQ";  
     if (!document.getElementById(jqc)) 
       document.write('<scr' + 'ipt type="text/javascript" id="' + jqc + '" src="' + jqCoreFilePath + '"></scr' + 'ipt>');
   
     // jQueryUI include
     var jqUI = "uiFileRefIDJQ";  
     if (!document.getElementById(jqUI)) 
       document.write('<scr' + 'ipt type="text/javascript" id="' + jqUI + '" src="' + jqUIFilePath + '"></scr' + 'ipt>');
   }
   
   include_jQueryFilesToPage();
   

3. I referenced the above jQueryIncluder.js file in another js or xsl file of my .Net project as following:

   <script type="text/javascript" src="~/includes/jQueryIncluder.js"></script>
   

I hope my effort is appreciated.

Thanks

The array declaration has incorrect syntax. Try the following, instead:

var numbers = [ 1, 2, 3, 4, 5]

The loop part seems right

$.each(numbers, function(val, text) {
            $('#items').append( $('<option></option>').val(val).html(text) )
            }); // there was also a ) missing here

As @Reigel did seems to add a bit more performance (it is not noticeable on such small arrays)

There is still another way to do it, which is using a particular NamingStrategy, which can be applied to a class or a property by decorating them with [JSonObject] or [JsonProperty].

There are predefined naming strategies like CamelCaseNamingStrategy, but you can implement your own ones.

The implementation of different naming strategies can be found here: https://github.com/JamesNK/Newtonsoft.Json/tree/master/Src/Newtonsoft.Json/Serialization

The answer is neither.

Docker Compose (herein referred to as compose) will use the Dockerfile if you add the build command to your project's docker-compose.yml.

Your Docker workflow should be to build a suitable Dockerfile for each image you wish to create, then use compose to assemble the images using the build command.

You can specify the path to your individual Dockerfiles using build /path/to/dockerfiles/blah where /path/to/dockerfiles/blah is where blah's Dockerfile lives.

Or you can use

<select [(ngModel)]="Answers[''+question.Name+'']" ng-options="option for option in question.Options">
        </select>

This is how I do it:

Then you should have a selector with diferent versions of the button, something like:

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

    <item android:drawable="@drawable/ic_button_red_pressed" android:state_pressed="true"/> <!-- pressed -->
    <item android:drawable="@drawable/ic_button_red_selected" android:state_focused="true"/> <!-- focused -->
    <item android:drawable="@drawable/ic_button_red_selected" android:state_selected="true"/> <!-- selected -->
    <item android:drawable="@drawable/ic_button_red_default"/> <!-- default -->

</selector>

hope this can help you..good luck

With Visual Studio Code 1.27.2:

1. When I go to File > Preference > Settings, I get the following tab

   

2. I type rulers in Search settings and I get the following list of settings

   

3. Clicking on the first Edit in settings.json, I can edit the user settings

   

4. Clicking on the pen icon that appears to the left of the setting in Default user settings I can copy it on the user settings and edit it

With Visual Studio Code 1.38.1, the screenshot shown on the third point changes to the following one.

The panel for selecting the default user setting values isn't shown anymore.

For Ubuntu users - Instead of changing the settings within the Chrome browser, which risks propagating them to other machines that do not have that issue, it is best to just edit the .desktop launcher:

Open the appropriate file for your situation.

/usr/share/applications/google-chrome.desktop
/usr/share/applications/chromium-browser.desktop

Just append the flag (-disable-gpu) to the end of the three Exec= lines in your file.

...
Exec=/usr/bin/google-chrome-stable %U -disable-gpu
...
Exec=/usr/bin/google-chrome-stable -disable-gpu
...
Exec=/usr/bin/google-chrome-stable --incognito -disable-gpu
...

use padding tags the above float tags didnt worked out, I used

padding left:5px; 



padding left :30px

Looking again at your question, I think I see what's wrong with your conf file. You set:

fullresolution=1366x768 windowresolution=1366x768

That's why you're getting the letterboxing (black on either side). You've essentially told Dosbox that your screen is the same size as your window, but your screen is actually bigger, 1600x900 (or higher) per the Googled specs for that computer. So the 'difference' shows up in black. So you either should change fullresolution to your actual screen resolution, or revert to fullresolution=original default, and only specify the window resolution.

So now I wonder if you really want fullscreen, though your question asks about only a window. For you are getting a window, but you sized it short of your screen, hence the two black stripes (letterboxing). If you really want fullscreen, then you need to specify the actual resolution of your screen. 1366x768 is not big enough.

The next issue is, what's the resolution of the program itself? It won't go past its own resolution. So if the program/game is (natively) say 1280x720 (HD), then your window resolution setting shouldn't be bigger than that (remember, it's fixed not dynamic when you use AxB as windowresolution).

Example: DOS Lotus 123 will only extend eight columns and 20 rows. The bigger the Dosbox, the bigger the text, but not more columns and rows. So setting a higher windowresolution for that, only results in bigger text, not more columns and rows. After that you'll have letterboxing.

Hope this helps you better.

Internal Methods

Bash supports arithmetic expansion with $(( expression )). For example:

$ echo $(( 5 * 5 ))
25

External Methods

A number of utilities provide arithmetic, including bc and expr.

$ echo '5 * 5' | /usr/bin/bc
25

$ /usr/bin/expr 5 \* 5

One situation I've run into was when dealing with milliseconds. FF and IE will not parse this date string correctly when trying to create a new date. "2014/11/24 17:38:20.177Z" They do not know how to handle .177Z. Chrome will work though.

"Hard Coding" means something that you want to embeded with your program or any project that can not be changed directly. For example if you are using a database server, then you must hardcode to connect your database with your project and that can not be changed by user. Because you have hard coded.

Try something like this. This should center any huge element in the middle vertically and horizontally with respect to its parent no matter both of their sizes.

.parent {
    position: relative;
    overflow: hidden;
    //optionally set height and width, it will depend on the rest of the styling used
}

.child {
    position: absolute;
    top: -9999px;
    bottom: -9999px;
    left: -9999px;
    right: -9999px;
    margin: auto;

}

This answer was given by Alex and I would like to recommend it. It worked for me and another thing it's straightforward and so simple.

setVisible(false); //you can't see me!
dispose(); //Destroy the JFrame object

just updated the springboot version to 2.1.3 and it worked of me

Why don't you run TOP and use the options to sort by other metrics, other than PID? Like, highest used PID from the CPU/MEM?

top -o cpu <---sorts all processes by CPU Usage

It can be very useful a few times, but in general, no fall-through is the desired behavior. Fall-through should be allowed, but not implicit.

An example, to update old versions of some data:

switch (version) {
    case 1:
        // Update some stuff
    case 2:
        // Update more stuff
    case 3:
        // Update even more stuff
    case 4:
        // And so on
}

Here is the solution for Ubuntu users

First we have to stop postgresql

sudo /etc/init.d/postgresql stop

Create a new file called /etc/apt/sources.list.d/pgdg.list and add below line

deb http://apt.postgresql.org/pub/repos/apt/ utopic-pgdg main

Follow below commands

wget -q -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get install postgresql-9.4
sudo pg_dropcluster --stop 9.4 main 
sudo /etc/init.d/postgresql start

Now we have everything, just need to upgrade it as below

sudo pg_upgradecluster 9.3 main
sudo pg_dropcluster 9.3 main

That's it. Mostly upgraded cluster will run on port number 5433. Check it with below command

sudo pg_lsclusters

You can use jQuery to do a POST for all your buttons. Just give them the same CssClass name.

Use "return false;" at the end of your onclick javascript event if you want to do a server side RedirectToAction after the post otherwise just return the view.

Razor Code

@using (Html.BeginForm())
{
    @Html.HiddenFor(model => model.ID) 
    @Html.ActionLink("Save", "SaveAction", "MainController", null, new { @class = "saveButton", onclick = "return false;" })
}

JQuery Code

$(document).ready(function () {
        $('.saveButton').click(function () {
            $(this).closest('form')[0].submit();
        });
    });

C#

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult SaveAction(SaveViewModel model)
{
    // Save code here...

    return RedirectToAction("Index");
    //return View(model);
}

If I am not mistaken, it will be onunload event.

I did this successfully, using the following steps.

Step 1: Create a folder in desktop, I give name it to "CrashReport" and put three files ("MYApp.app", "MyApp.app.dSYM", "MYApp_2013-07-18.crash") in it.

Step 2: Open Finder and go to Applications, where you will find the Xcode application, right click on this and Click "Show Package Contents", after this follow this simple path. "Contents->Developer->Platforms->iPhoneOS.platform->Developer->Library->PrivateFrameworks->DTDeviceKit.framework->Versions->A->Resources"

OR

"Contents->Developer->Platforms->iPhoneOS.platform->Developer->Library->PrivateFrameworks->DTDeviceKitBase.framework->Versions->A->Resources"

OR

For Xcode 6 and above the path is Applications/Xcode.app/Contents/SharedFrameworks/DTDeviceKitBase.framework/Versions/A/Resources

Where you find "symbolicatecrash" file, copy this and paste it to "CrashReport" folder.

Step 3: launch the terminal, run these 3 Command

1. cd /Users/mac38/Desktop/CrashReport and press Enter button

2. export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer" and press Enter

3. ./symbolicatecrash -A -v MYApp_2013-07-18.crash MyApp.app.dSYM and press Enter Now its Done.. (NOTE: versions around 6.4 or later do not have the -A option -- just leave it out).

One thing, regardless of how you initialize the field, use of the final qualifier, if possible, will ensure the visibility of the field's value in a multi-threaded environment.

Determine if a cell is within a range using VBA in Microsoft Excel:

From the linked site (maintaining credit to original submitter):

VBA macro tip contributed by Erlandsen Data Consulting offering Microsoft Excel Application development, template customization, support and training solutions

Function InRange(Range1 As Range, Range2 As Range) As Boolean
    ' returns True if Range1 is within Range2
    InRange = Not (Application.Intersect(Range1, Range2) Is Nothing)
End Function


Sub TestInRange()
    If InRange(ActiveCell, Range("A1:D100")) Then
        ' code to handle that the active cell is within the right range
        MsgBox "Active Cell In Range!"
    Else
        ' code to handle that the active cell is not within the right range
        MsgBox "Active Cell NOT In Range!"
    End If
End Sub

It exists a property called XmlElementAttribute.IsNullable

If the IsNullable property is set to true, the xsi:nil attribute is generated for class members that have been set to a null reference.

The following example shows a field with the XmlElementAttribute applied to it, and the IsNullable property set to false.

public class MyClass
{
   [XmlElement(IsNullable = false)]
   public string Group;
}

You can have a look to other XmlElementAttribute for changing names in serialization etc.

In easy words.

Images -

The file system and configuration(read-only) application which is used to create containers. More detail.

Containers -

The major difference between a container and an image is the top writable layer. Containers are running instances of Docker images with top writable layer. Containers run the actual applications. A container includes an application and all of its dependencies. When the container is deleted, the writable layer is also deleted. The underlying image remains unchanged. More detail.

Other important terms to notice:

Docker daemon -

The background service running on the host that manages the building, running and distributing Docker containers.

Docker client -

The command line tool that allows the user to interact with the Docker daemon.

Docker Store -

Store is, among other things, a registry of Docker images. You can think of the registry as a directory of all available Docker images.

A picture from this blog post is worth a thousand words.

(For deeper understanding please read this.)

Summary:

• Pull image from Docker hub or build from a Dockerfile => Gives a Docker image (not editable).
• Run the image (docker run image_name:tag_name) => Gives a running Image i.e. container (editable)

I had a similar issue. pytest did not recognize a module installed in the environment I was working in.

I resolved it by also installing pytest into the same environment.

If a case-insensitive comparison is acceptable, just use =:

=IF(A1="ENG",1,0)

Try this :

   for match in re.finditer(r"\[P[^\]]*\](.*?)\[/P\]", subject):
        # match start: match.start()
        # match end (exclusive): match.end()
        # matched text: match.group()

Sometimes the simple method is the best. Just pad your strings with spaces. If it is only a few textboxes etc this is by far the simplest method.

You can also simply insert blank columns/rows with a fixed size. Extremely simple and you can easily change it.

A normal variable is set by simply assigning it a value; note that no whitespace is allowed around the =:

HOME=c

An environment variable is a regular variable that has been marked for export to the environment.

export HOME
HOME=c

You can combine the assignment with the export statement.

export HOME=c

You also could just throw new HttpMessageNotReadableException("error description") to benefit from Spring's default error handling.

However, just as is the case with those default errors, no response body will be set.

I find these useful when rejecting requests that could reasonably only have been handcrafted, potentially indicating a malevolent intent, since they obscure the fact that the request was rejected based on a deeper, custom validation and its criteria.

Hth, dtk

The accepted answer has some holes in it. The beauty of the SparseArray is that it allows gaps in the indeces. So, we could have two maps like so, in a SparseArray...

(0,true)
(250,true)

Notice the size here would be 2. If we iterate over size, we will only get values for the values mapped to index 0 and index 1. So the mapping with a key of 250 is not accessed.

for(int i = 0; i < sparseArray.size(); i++) {
   int key = sparseArray.keyAt(i);
   // get the object by the key.
   Object obj = sparseArray.get(key);
}

The best way to do this is to iterate over the size of your data set, then check those indeces with a get() on the array. Here is an example with an adapter where I am allowing batch delete of items.

for (int index = 0; index < mAdapter.getItemCount(); index++) {
     if (toDelete.get(index) == true) {
        long idOfItemToDelete = (allItems.get(index).getId());
        mDbManager.markItemForDeletion(idOfItemToDelete);
        }
    }

I think ideally the SparseArray family would have a getKeys() method, but alas it does not.

The trick is to input the right redirect url at the point of creating the ID. I found that updating the redirect url once the ID has been created via an 'Edit' just doesn't get the job done. What also worked for me is duplicating the entire 'vendor' folder and copying it to the same location where the 'oauth' file is (just until you successfully generate the token and then you can delete the duplicate 'vendor' folder). This is because trying to point to the vendor folder via '../vendor/autoload' didn't work for me.

So, delete your existing troublesome Client OAuth ID and try this approach, it will work.

While the previous answers do scale the image and take care of the aspect ratio, the resampling itself should be done so that there is no aliasing. Taking care of scale is a matter of fixing arguments correctly. There are many comments about the quality of the output images from standard scaling call. to maintain quality of the image one should use the standard call:

Bitmap resizedBitmap = Bitmap.createScaledBitmap(originalBitmap, newWidth, newHeight, true);

with the last argument set to true because it will do the bilinear filtering for resampling to prevent aliasing. Read more about aliasing here: https://en.wikipedia.org/wiki/Aliasing

From android documentation:

https://developer.android.com/reference/android/graphics/Bitmap#createScaledBitmap(android.graphics.Bitmap,%20int,%20int,%20boolean)

public static Bitmap createScaledBitmap (Bitmap src, 
                int dstWidth, 
                int dstHeight, 
                boolean filter)

filter : boolean, Whether or not bilinear filtering should be used when scaling the bitmap. If this is true then bilinear filtering will be used when scaling which has better image quality at the cost of worse performance. If this is false then nearest-neighbor scaling is used instead which will have worse image quality but is faster. Recommended default is to set filter to 'true' as the cost of bilinear filtering is typically minimal and the improved image quality is significant.

    if (divEl.is(':visible')) {
        console.log("it's visible now!");
    }
});
ro.observe(divEl[0]);

Note that it's crossbrowser and performant (no polling).

I recently had to change the ownership of all objects in a database. Although tables, views, triggers and sequences were somewhat easily changed the above approach failed for functions as the signature is part of the function name. Granted, I have a MySQL background and am not that familiar with Postgres.

However, pg_dump allows you to dump just the schema and this contains the ALTER xxx OWNER TO yyy; statements you need. Here is my bit of shell magic on the topic

pg_dump -s YOUR_DB | grep -i 'owner to' | sed -e 's/OWNER TO .*;/OWNER TO NEW_OWNER;/i' | psqL YOUR_DB

yu have to install the correct version for your computer 32 or 63 bits thats all

When using Minikube, you can get the IP and port through which you can access the service by running:

minikube service [service name]

E.g.:

minikube service kubia-http

Handling multiple extensions

In the case where you have multiple extensions this one-liner using pathlib and str.replace works a treat:

Remove/strip extensions

>>> from pathlib import Path
>>> p = Path("/path/to/myfile.tar.gz")
>>> extensions = "".join(p.suffixes)

# any python version
>>> str(p).replace(extensions, "")
'/path/to/myfile'

# python>=3.9
>>> str(p).removesuffix(extensions)
'/path/to/myfile'

Replace extensions

>>> p = Path("/path/to/myfile.tar.gz")
>>> extensions = "".join(p.suffixes)
>>> new_ext = ".jpg"
>>> str(p).replace(extensions, new_ext)
'/path/to/myfile.jpg'

If you also want a pathlib object output then you can obviously wrap the line in Path()

>>> Path(str(p).replace("".join(p.suffixes), ""))
PosixPath('/path/to/myfile')

Wrapping it all up in a function

from pathlib import Path
from typing import Union

PathLike = Union[str, Path]


def replace_ext(path: PathLike, new_ext: str = "") -> Path:
    extensions = "".join(Path(path).suffixes)
    return Path(str(p).replace(extensions, new_ext))


p = Path("/path/to/myfile.tar.gz")
new_ext = ".jpg"

assert replace_ext(p, new_ext) == Path('/path/to/myfile.jpg')
assert replace_ext(str(p), new_ext) == Path('/path/to/myfile.jpg')
assert replace_ext(p) == Path('/path/to/myfile')
    

You're declaring everything in the parent page. So the references to window and document are to the parent page's. If you want to do stuff to the iframe's, use iframe || iframe.contentWindow to access its window, and iframe.contentDocument || iframe.contentWindow.document to access its document.

There's a word for what's happening, possibly "lexical scope": What is lexical scope?

The only context of a scope is this. And in your example, the owner of the method is doc, which is the iframe's document. Other than that, anything that's accessed in this function that uses known objects are the parent's (if not declared in the function). It would be a different story if the function were declared in a different place, but it's declared in the parent page.

This is how I would write it:

(function () {
  var dom, win, doc, where, iframe;

  iframe = document.createElement('iframe');
  iframe.src = "javascript:false";

  where = document.getElementsByTagName('script')[0];
  where.parentNode.insertBefore(iframe, where);

  win = iframe.contentWindow || iframe;
  doc = iframe.contentDocument || iframe.contentWindow.document;

  doc.open();
  doc._l = (function (w, d) {
    return function () {
      w.vanishing_global = new Date().getTime();

      var js = d.createElement("script");
      js.src = 'test-vanishing-global.js?' + w.vanishing_global;

      w.name = "foobar";
      d.foobar = "foobar:" + Math.random();
      d.foobar = "barfoo:" + Math.random();
      d.body.appendChild(js);
    };
  })(win, doc);
  doc.write('<body onload="document._l();"></body>');
  doc.close();
})();

The aliasing of win and doc as w and d aren't necessary, it just might make it less confusing because of the misunderstanding of scopes. This way, they are parameters and you have to reference them to access the iframe's stuff. If you want to access the parent's, you still use window and document.

I'm not sure what the implications are of adding methods to a document (doc in this case), but it might make more sense to set the _l method on win. That way, things can be run without a prefix...such as <body onload="_l();"></body>

Just use the "test" binary directly to do this. You also should use the noop command ":" if you don't want to specify an "else" condition, so docker does not stop with a non zero return value error.

RUN test -z "$YOURVAR" || echo "var is set" && echo "var is not set"
RUN test -z "$YOURVAR" && echo "var is not set" || :
RUN test -z "$YOURVAR" || echo "var is set" && :

For Microsoft Visual Studio Community 2017 use Ctrl+Alt+A

Alternatively from command panel view -> Other Windows -> Command Window

The C standard (actually C99, I'm not up to date) says:

Alphabetic escape sequences representing nongraphic characters in the execution character set are intended to produce actions on display devices as follows:

\b (backspace) Moves the active position to the previous position on the current line. [...]

\t (horizontal tab) Moves the active position to the next horizontal tabulation position on the current line. [...]

Both just move the active position, neither are supposed to write any character on or over another character. To overwrite with a space you could try: puts("foo\b \tbar"); but note that on some display devices - say a daisy wheel printer - the o will show the transparent space.

You dont actually need the @Query annotation at all.

You can just use the following

    @Repository("registerUserRepository")
    public interface RegisterUserRepository extends JpaRepository<Registration,Long>{
    
    List<Registration> findByPlaceIgnoreCaseContaining(String place);

    }

Using the PHPExcel library to read an Excel file and transfer the data into a database

//  Include PHPExcel_IOFactory
include 'PHPExcel/IOFactory.php';

$inputFileName = './sampleData/example1.xls';

//  Read your Excel workbook
try {
    $inputFileType = PHPExcel_IOFactory::identify($inputFileName);
    $objReader = PHPExcel_IOFactory::createReader($inputFileType);
    $objPHPExcel = $objReader->load($inputFileName);
} catch(Exception $e) {
    die('Error loading file "'.pathinfo($inputFileName,PATHINFO_BASENAME).'": '.$e->getMessage());
}

//  Get worksheet dimensions
$sheet = $objPHPExcel->getSheet(0); 
$highestRow = $sheet->getHighestRow(); 
$highestColumn = $sheet->getHighestColumn();

//  Loop through each row of the worksheet in turn
for ($row = 1; $row <= $highestRow; $row++){ 
    //  Read a row of data into an array
    $rowData = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row,
                                    NULL,
                                    TRUE,
                                    FALSE);
    //  Insert row data array into your database of choice here
}

Anything more becomes very dependent on your database, and how you want the data structured in it

In general, you want to go from XML to regular objects of your language (since there are usually reasonable tools to do this, and it's the harder conversion). And then from Plain Old Object produce JSON -- there are tools for this, too, and it's a quite simple serialization (since JSON is "Object Notation", natural fit for serializing objects). I assume Python has its set of tools.

For me it was much more simple but it took me a while to figure it out. We basically had in our .jslib

some_array.forEach(item => {
    do_stuff(item);
});

Turns out Unity (emscripten?) just doesn't like that syntax. We replaced it with a good old for-loop and it stoped complaining right away. I really hate it that it doesn't show the line it is complaining about, but anyway, fool me twice shame on me.

You can also set your div with the following:

#something {width: 400px; margin: auto;}

With that setting, the div will have a set width, and the margin and either side will automatically set depending on the with of the browser.

--- Create new config in signingConfigs

unsigned {
        //do not sign
    }

--- Create build type in buildTypes

unsigned {
        versionNameSuffix '-unsigned'
    }

--- Go to build variants and chose unsigned standard. Build project.

--- Go to "outputs/apk" and find "XXX-unsigned.apk". To check if it is unsigned try to install it to device - you'll fail.

you can use this code .may be solve the problem

Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://192.168.43.1:6789/mobile_base/test.apk"));
startActivity(intent);

You can use git for exactly this purpose. Basically, you create a git repository in folder A (the repo is in A/.git), then copy A/.git to B/.git, then change to B folder and compare simply by running git diff. And the --exclude functionality can be achieved with .gitignore.

So, sticking to your example (but using bash shell on Linux):

# Create a Git repo in current_vss
pushd current_vss
printf ".svn\n*.vspscc\n*.scc" >> .gitignore
git init && git add . && git commit -m 'initial'
popd

# Copy the repo to current_svn and compare
cp -r current_vss/.git* current_svn/
pushd current_svn
git diff

Others have noted that you can use the built-in File.ReadAllBytes. The built-in method is fine, but it's worth noting that the code you post above is fragile for two reasons:

1. Stream is IDisposable - you should place the FileStream fs = new FileStream(filename, FileMode.Open,FileAccess.Read) initialization in a using clause to ensure the file is closed. Failure to do this may mean that the stream remains open if a failure occurs, which will mean the file remains locked - and that can cause other problems later on.
2. fs.Read may read fewer bytes than you request. In general, the .Read method of a Stream instance will read at least one byte, but not necessarily all bytes you ask for. You'll need to write a loop that retries reading until all bytes are read. This page explains this in more detail.

You should include <string.h> (or its C++ equivalent, <cstring>).

If you don't want to make any change to you code just to make your IDE happy. I have solved it by adding all components to the Spring facet.

1. Create a group with name "Service, Processors and Routers" or any name you like;
2. Remove and recreate "Spring Application Context" use the group you created previously as a parent.

I would not advise a regex answer from Bart, I find parsing solution better in this particular case (as Fabian proposed). I've tried regex solution and own parsing implementation I have found that:

1. Parsing is much faster than splitting with regex with backreferences - ~20 times faster for short strings, ~40 times faster for long strings.
2. Regex fails to find empty string after last comma. That was not in original question though, it was mine requirement.

My solution and test below.

String tested = "foo,bar,c;qual=\"baz,blurb\",d;junk=\"quux,syzygy\",";
long start = System.nanoTime();
String[] tokens = tested.split(",(?=([^\"]*\"[^\"]*\")*[^\"]*$)");
long timeWithSplitting = System.nanoTime() - start;

start = System.nanoTime(); 
List<String> tokensList = new ArrayList<String>();
boolean inQuotes = false;
StringBuilder b = new StringBuilder();
for (char c : tested.toCharArray()) {
    switch (c) {
    case ',':
        if (inQuotes) {
            b.append(c);
        } else {
            tokensList.add(b.toString());
            b = new StringBuilder();
        }
        break;
    case '\"':
        inQuotes = !inQuotes;
    default:
        b.append(c);
    break;
    }
}
tokensList.add(b.toString());
long timeWithParsing = System.nanoTime() - start;

System.out.println(Arrays.toString(tokens));
System.out.println(tokensList.toString());
System.out.printf("Time with splitting:\t%10d\n",timeWithSplitting);
System.out.printf("Time with parsing:\t%10d\n",timeWithParsing);

Of course you are free to change switch to else-ifs in this snippet if you feel uncomfortable with its ugliness. Note then lack of break after switch with separator. StringBuilder was chosen instead to StringBuffer by design to increase speed, where thread safety is irrelevant.

Here's a sample class:

public class Increment
{
    public static void main(String [] args)
    {
        for (int i = 0; i < args.length; ++i)
        {
            System.out.println(args[i]);
        }
    }
}

If I disassemble this class using javap.exe I get this:

Compiled from "Increment.java"
public class Increment extends java.lang.Object{
public Increment();
  Code:
   0:   aload_0
   1:   invokespecial   #1; //Method java/lang/Object."<init>":()V
   4:   return

public static void main(java.lang.String[]);
  Code:
   0:   iconst_0
   1:   istore_1
   2:   iload_1
   3:   aload_0
   4:   arraylength
   5:   if_icmpge       23
   8:   getstatic       #2; //Field java/lang/System.out:Ljava/io/PrintStream;
   11:  aload_0
   12:  iload_1
   13:  aaload
   14:  invokevirtual   #3; //Method java/io/PrintStream.println:(Ljava/lang/String;)V
   17:  iinc    1, 1
   20:  goto    2
   23:  return

}

If I change the loop so it uses i++ and disassemble again I get this:

Compiled from "Increment.java"
public class Increment extends java.lang.Object{
public Increment();
  Code:
   0:   aload_0
   1:   invokespecial   #1; //Method java/lang/Object."<init>":()V
   4:   return

public static void main(java.lang.String[]);
  Code:
   0:   iconst_0
   1:   istore_1
   2:   iload_1
   3:   aload_0
   4:   arraylength
   5:   if_icmpge       23
   8:   getstatic       #2; //Field java/lang/System.out:Ljava/io/PrintStream;
   11:  aload_0
   12:  iload_1
   13:  aaload
   14:  invokevirtual   #3; //Method java/io/PrintStream.println:(Ljava/lang/String;)V
   17:  iinc    1, 1
   20:  goto    2
   23:  return

}

When I compare the two, TextPad tells me that the two are identical.

What this says is that from the point of view of the generated byte code there's no difference in a loop. In other contexts there is a difference between ++i and i++, but not for loops.

@Coincoin

The real power of the foreach extension method involves reusability of the Action<> without adding unnecessary methods to your code. Say that you have 10 lists and you want to perform the same logic on them, and a corresponding function doesn't fit into your class and is not reused. Instead of having ten for loops, or a generic function that is obviously a helper that doesn't belong, you can keep all of your logic in one place (the Action<>. So, dozens of lines get replaced with

Action<blah,blah> f = { foo };

List1.ForEach(p => f(p))
List2.ForEach(p => f(p))

etc...

The logic is in one place and you haven't polluted your class.

You seem to want to use a CURSOR. Though most of the times it's best to use a set based solution, there are some times where a CURSOR is the best solution. Without knowing more about your real problem, we can't help you more than that:

DECLARE @PractitionerId int

DECLARE MY_CURSOR CURSOR 
  LOCAL STATIC READ_ONLY FORWARD_ONLY
FOR 
SELECT DISTINCT PractitionerId 
FROM Practitioner

OPEN MY_CURSOR
FETCH NEXT FROM MY_CURSOR INTO @PractitionerId
WHILE @@FETCH_STATUS = 0
BEGIN 
    --Do something with Id here
    PRINT @PractitionerId
    FETCH NEXT FROM MY_CURSOR INTO @PractitionerId
END
CLOSE MY_CURSOR
DEALLOCATE MY_CURSOR

Just adding a point to previous answers that in MySQL we can either use

table_factor syntax 

OR

joined_table syntax

mysql documentation

Table_factor example

SELECT prd.name, b.name 
FROM products prd, buyers b

Joined Table example

SELECT prd.name, b.name 
FROM products prd
 left join buyers b on b.bid = prd.bid;

FYI: Please ignore the fact the the left join on the joined table example doesnot make much sense (in reality we would use some sort of join table to link buyer to the product table instead of saving buyerID in product table).

Probably the most definitive is Figure B.1(d) of the ggplot2 book, the appendices of which are available at http://ggplot2.org/book/appendices.pdf.

However, it is not quite that simple. hjust and vjust as described there are how it works in geom_text and theme_text (sometimes). One way to think of it is to think of a box around the text, and where the reference point is in relation to that box, in units relative to the size of the box (and thus different for texts of different size). An hjust of 0.5 and a vjust of 0.5 center the box on the reference point. Reducing hjust moves the box right by an amount of the box width times 0.5-hjust. Thus when hjust=0, the left edge of the box is at the reference point. Increasing hjust moves the box left by an amount of the box width times hjust-0.5. When hjust=1, the box is moved half a box width left from centered, which puts the right edge on the reference point. If hjust=2, the right edge of the box is a box width left of the reference point (center is 2-0.5=1.5 box widths left of the reference point. For vertical, less is up and more is down. This is effectively what that Figure B.1(d) says, but it extrapolates beyond [0,1].

But, sometimes this doesn't work. For example

DF <- data.frame(x=c("a","b","cdefghijk","l"),y=1:4)
p <- ggplot(DF, aes(x,y)) + geom_point()

p + opts(axis.text.x=theme_text(vjust=0))
p + opts(axis.text.x=theme_text(vjust=1))
p + opts(axis.text.x=theme_text(vjust=2))

The three latter plots are identical. I don't know why that is. Also, if text is rotated, then it is more complicated. Consider

p + opts(axis.text.x=theme_text(hjust=0, angle=90))
p + opts(axis.text.x=theme_text(hjust=0.5 angle=90))
p + opts(axis.text.x=theme_text(hjust=1, angle=90))
p + opts(axis.text.x=theme_text(hjust=2, angle=90))

The first has the labels left justified (against the bottom), the second has them centered in some box so their centers line up, and the third has them right justified (so their right sides line up next to the axis). The last one, well, I can't explain in a coherent way. It has something to do with the size of the text, the size of the widest text, and I'm not sure what else.

If your function have two vector variables and must compute itself on each value of them (as mentioned by @Ari B. Friedman) you can use mapply as follows:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
mapply(mult_one,vars1,vars2)

which gives you:

> mapply(mult_one,vars1,vars2)
[1] 10 40 90

That should be what --link is for, at least for the hostname part.
With docker 1.10, and PR 19242, that would be:

docker network create --net-alias=[]: Add network-scoped alias for the container

(see last section below)

That is what Updating the /etc/hosts file details

In addition to the environment variables, Docker adds a host entry for the source container to the /etc/hosts file.

For instance, launch an LDAP server:

docker run -t  --name openldap -d -p 389:389 larrycai/openldap

And define an image to test that LDAP server:

FROM ubuntu
RUN apt-get -y install ldap-utils
RUN touch /root/.bash_aliases
RUN echo "alias lds='ldapsearch -H ldap://internalopenldap -LL -b
ou=Users,dc=openstack,dc=org -D cn=admin,dc=openstack,dc=org -w
password'" > /root/.bash_aliases
ENTRYPOINT bash

You can expose the 'openldap' container as 'internalopenldap' within the test image with --link:

 docker run -it --rm --name ldp --link openldap:internalopenldap ldaptest

Then, if you type 'lds', that alias will work:

ldapsearch -H ldap://internalopenldap ...

That would return people. Meaning internalopenldap is correctly reached from the ldaptest image.

Of course, docker 1.7 will add libnetwork, which provides a native Go implementation for connecting containers. See the blog post.
It introduced a more complete architecture, with the Container Network Model (CNM)

That will Update the Docker CLI with new “network” commands, and document how the “-net” flag is used to assign containers to networks.

docker 1.10 has a new section Network-scoped alias, now officially documented in network connect:

While links provide private name resolution that is localized within a container, the network-scoped alias provides a way for a container to be discovered by an alternate name by any other container within the scope of a particular network.
Unlike the link alias, which is defined by the consumer of a service, the network-scoped alias is defined by the container that is offering the service to the network.

Continuing with the above example, create another container in isolated_nw with a network alias.

$ docker run --net=isolated_nw -itd --name=container6 -alias app busybox
8ebe6767c1e0361f27433090060b33200aac054a68476c3be87ef4005eb1df17

--alias=[]         

Add network-scoped alias for the container

You can use --link option to link another container with a preferred alias

You can pause, restart, and stop containers that are connected to a network. Paused containers remain connected and can be revealed by a network inspect. When the container is stopped, it does not appear on the network until you restart it.

If specified, the container's IP address(es) is reapplied when a stopped container is restarted. If the IP address is no longer available, the container fails to start.

One way to guarantee that the IP address is available is to specify an --ip-range when creating the network, and choose the static IP address(es) from outside that range. This ensures that the IP address is not given to another container while this container is not on the network.

$ docker network create --subnet 172.20.0.0/16 --ip-range 172.20.240.0/20 multi-host-network

$ docker network connect --ip 172.20.128.2 multi-host-network container2
$ docker network connect --link container1:c1 multi-host-network container2

If you just have a static svg string you want to include, you can use dangerouslySetInnerHTML:

render: function() {
    return <span dangerouslySetInnerHTML={{__html: "<svg>...</svg>"}} />;
}

and React will include the markup directly without processing it at all.

Create a copy constructor:

class DummyBean {
  private String dummy;

  public DummyBean(DummyBean another) {
    this.dummy = another.dummy; // you can access  
  }
}

Every object has also a clone method which can be used to copy the object, but don't use it. It's way too easy to create a class and do improper clone method. If you are going to do that, read at least what Joshua Bloch has to say about it in Effective Java.

Update: Apparently possible by passing a flag to mysql_connect(). See Executing multiple SQL queries in one statement with PHP Nevertheless, any current reader should avoid using the mysql_-class of functions and prefer PDO.

You can't do that using the regular mysql-api in PHP. Just execute two queries. The second one will be so fast that it won't matter. This is a typical example of micro optimization. Don't worry about it.

For the record, it can be done using mysqli and the mysqli_multi_query-function.

Make sure that project name doesn't contain special character.

JSON.parse() is for "parsing" something that was received as JSON.
JSON.stringify() is to create a JSON string out of an object/array.

If you aren’t using Auto Layout, have you tried setting the child view’s autoresize mask? Try this:

myChildeView.autoresizingMask = (UIViewAutoresizingFlexibleWidth |
                                 UIViewAutoresizingFlexibleHeight);

Also, you may need to call

myParentView.autoresizesSubviews = YES;

to get the parent view to resize its subviews automatically when its frame changes.

If you’re still seeing the child view drawing outside of the parent view’s frame, there’s a good chance that the parent view is not clipping its contents. To fix that, call

myParentView.clipsToBounds = YES;

In javascript:

document.getElementById("myDIV").style.display = "none";

and in jquery:

$("#myDIV").css({display: "none"});
$("#myDIV").css({display: "block"});

and you can use:

$('#myDIV').hide();
$('#myDIV').show();

You should use the preprocessor macro __LINE__ and __FILE__. They are predefined macros and part of the C/C++ standard. During preprocessing, they are replaced respectively by a constant string holding an integer representing the current line number and by the current file name.

Others preprocessor variables :

• __func__ : function name (this is part of C99, not all C++ compilers support it)
• __DATE__ : a string of form "Mmm dd yyyy"
• __TIME__ : a string of form "hh:mm:ss"

Your code will be :

if(!Logical)
  printf("Not logical value at line number %d in file %s\n", __LINE__, __FILE__);

If you're using a linux server for your application then it is necessary to use lowercase file name and class name to avoid this issue.

Ex.

Filename: csvsample.php

class csvsample {

}

Just do this
