Something like this should work (it did for me). The reason for wanting to use -Filter instead of -Include is that include takes a huge performance hit compared to -Filter.

Below just loops each file type and multiple servers/workstations specified in separate files.

##  
##  This script will pull from a list of workstations in a text file and search for the specified string


## Change the file path below to where your list of target workstations reside
## Change the file path below to where your list of filetypes reside

$filetypes = gc 'pathToListOffiletypes.txt'
$servers = gc 'pathToListOfWorkstations.txt'

##Set the scope of the variable so it has visibility
set-variable -Name searchString -Scope 0
$searchString = 'whatYouAreSearchingFor'

foreach ($server in $servers)
    {

    foreach ($filetype in $filetypes)
    {

    ## below creates the search path.  This could be further improved to exclude the windows directory
    $serverString = "\\"+$server+"\c$\Program Files"


    ## Display the server being queried
    write-host “Server:” $server "searching for " $filetype in $serverString

    Get-ChildItem -Path $serverString -Recurse -Filter $filetype |
    #-Include "*.xml","*.ps1","*.cnf","*.odf","*.conf","*.bat","*.cfg","*.ini","*.config","*.info","*.nfo","*.txt" |
    Select-String -pattern $searchstring | group path | select name | out-file f:\DataCentre\String_Results.txt

    $os = gwmi win32_operatingsystem -computer $server
    $sp = $os | % {$_.servicepackmajorversion}
    $a = $os | % {$_.caption}

    ##  Below will list again the server name as well as its OS and SP
    ##  Because the script may not be monitored, this helps confirm the machine has been successfully scanned
        write-host $server “has completed its " $filetype "scan:” “|” “OS:” $a “SP:” “|” $sp


    }

}
#end script

With New-Item you can add the Force parameter

New-Item -Force -ItemType directory -Path foo

Or the ErrorAction parameter

New-Item -ErrorAction Ignore -ItemType directory -Path foo

I had this same problem too, and it was tricky. For me, it was because I'm using Ext.Js javascript library. If you are doing a response.redirect in server-side code that you accessed in an Ajax call, there are problems. Ext.js has a workaround with their Ext.Redirect method.

This will also work:

<Hyperlink Command="{Binding RelativeSource={RelativeSource AncestorType=ItemsControl},
                             Path=DataContext.AllowItemCommand}" />

ListView will inherit its DataContext from Window, so it's available at this point, too.
And since ListView, just like similar controls (e. g. Gridview, ListBox, etc.), is a subclass of ItemsControl, the Binding for such controls will work perfectly.

If use webstorm, press Ctrl+Alt+S and bring up the settings window. Languages&Frameworks>TypeScript, enable "use tsconfig.json" option.

API stands for Application Programming Interface, i.e. API is the way for an application to interact with certain system/application/library/etc.

For example, there are API's for OS (WinAPI), API's for other applications (like databases) and for specific libraries (for example, image processing), etc.

APIs are usually developed in a form consumable by a client application. For C/C++ applications, it a set header files and dynamic/static libraries. For Java - set of jars. And so on.

If you need your script to be portable and you would rather not have any 3rd party dependencies, this is how you send POST request purely in Python 3.

from urllib.parse import urlencode
from urllib.request import Request, urlopen

url = 'https://httpbin.org/post' # Set destination URL here
post_fields = {'foo': 'bar'}     # Set POST fields here

request = Request(url, urlencode(post_fields).encode())
json = urlopen(request).read().decode()
print(json)

Sample output:

{
  "args": {}, 
  "data": "", 
  "files": {}, 
  "form": {
    "foo": "bar"
  }, 
  "headers": {
    "Accept-Encoding": "identity", 
    "Content-Length": "7", 
    "Content-Type": "application/x-www-form-urlencoded", 
    "Host": "httpbin.org", 
    "User-Agent": "Python-urllib/3.3"
  }, 
  "json": null, 
  "origin": "127.0.0.1", 
  "url": "https://httpbin.org/post"
}

In case anybody else falls onto this page, you can also solve this by using the Ip address in the URL request instead of the domain:

NSURL *myURL = [NSURL URLWithString:@"http://10.0.0.2/mypage.php"];

Then you specify the Host manually:

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:myURL];
[request setAllHTTPHeaderFields:[NSDictionary dictionaryWithObjectAndKeys:@"myserver",@"Host"]];

As far as the server is concerned, it will behave the exact same way as if you had used http://myserver/mypage.php, except that the iPhone will not have to do a DNS lookup.

100% Public API.

This query should work for you:

SELECT *
FROM table
WHERE MONTH(columnName) = MONTH(CURRENT_DATE())
AND YEAR(columnName) = YEAR(CURRENT_DATE())

Try this

function disable(i){
    $("#rbutton_"+i).attr("disabled",true);
}

The necessary method is Mockito#verify:

public static <T> T verify(T mock,
                           VerificationMode mode)

mock is your mocked object and mode is the VerificationMode that describes how the mock should be verified. Possible modes are:

verify(mock, times(5)).someMethod("was called five times");
verify(mock, never()).someMethod("was never called");
verify(mock, atLeastOnce()).someMethod("was called at least once");
verify(mock, atLeast(2)).someMethod("was called at least twice");
verify(mock, atMost(3)).someMethod("was called at most 3 times");
verify(mock, atLeast(0)).someMethod("was called any number of times"); // useful with captors
verify(mock, only()).someMethod("no other method has been called on the mock");

You'll need these static imports from the Mockito class in order to use the verify method and these verification modes:

import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.atLeastOnce;
import static org.mockito.Mockito.atMost;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.only;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;

So in your case the correct syntax will be:

Mockito.verify(mock, times(4)).send()

This verifies that the method send was called 4 times on the mocked object. It will fail if it was called less or more than 4 times.

If you just want to check, if the method has been called once, then you don't need to pass a VerificationMode. A simple

verify(mock).someMethod("was called once");

would be enough. It internally uses verify(mock, times(1)).someMethod("was called once");.

It is possible to have multiple verification calls on the same mock to achieve a "between" verification. Mockito doesn't support something like this verify(mock, between(4,6)).someMethod("was called between 4 and 6 times");, but we can write

verify(mock, atLeast(4)).someMethod("was called at least four times ...");
verify(mock, atMost(6)).someMethod("... and not more than six times");

instead, to get the same behaviour. The bounds are included, so the test case is green when the method was called 4, 5 or 6 times.

I ran into this problem a few times. Many of the solutions will run the rm command for each individual file that needs to be deleted. This is very inefficient:

find . -name "*.pdf" -print0 | xargs -0 rm -rf

I ended up writing a python script to delete the files based on the first 4 characters in the file-name:

import os
filedir = '/tmp/' #The directory you wish to run rm on 
filelist = (os.listdir(filedir)) #gets listing of all files in the specified dir
newlist = [] #Makes a blank list named newlist
for i in filelist: 
    if str((i)[:4]) not in newlist: #This makes sure that the elements are unique for newlist
        newlist.append((i)[:4]) #This takes only the first 4 charcters of the folder/filename and appends it to newlist
for i in newlist:
    if 'tmp' in i:  #If statment to look for tmp in the filename/dirname
        print ('Running command rm -rf '+str(filedir)+str(i)+'* : File Count: '+str(len(os.listdir(filedir)))) #Prints the command to be run and a total file count
        os.system('rm -rf '+str(filedir)+str(i)+'*') #Actual shell command
print ('DONE')

This worked very well for me. I was able to clear out over 2 million temp files in a folder in about 15 minutes. I commented the tar out of the little bit of code so anyone with minimal to no python knowledge can manipulate this code.

Since this is a POD (essentially a C struct) there is little harm in initialising it the C way:

Snapshot s;
memset(&s, 0, sizeof (s));

or similarly

Snapshot *sp = new Snapshot;
memset(sp, 0, sizeof (*sp));

I wouldn't go so far as to use calloc() in a C++ program though.

When writing queries with our server LIKE or INSTR (or CHARINDEX in T-SQL) takes too long, so we use LEFT like in the following structure:

select *
from little
left join big
on left( big.key, len(little.key) ) = little.key

I understand that might only work with varying endings to the query, unlike other suggestions with '%' + b + '%', but is enough and much faster if you only need b+'%'.

Another way to optimize it for speed (but not memory) is to create a column in "little" that is "len(little.key)" as "lenkey" and user that instead in the query above.

Assuming the ID is unique:

var result = xmldoc.Element("Customers")
                   .Elements("Customer")
                   .Single(x => (int?)x.Attribute("ID") == 2);

You could also use First, FirstOrDefault, SingleOrDefault or Where, instead of Single for different circumstances.

In addition to @StephaneDelcroix's answer, before using:

git clone [email protected]/my-project.git .

make sure that your current dir is empty by using

ls -a

You can include your header function wherever you like, as long as NO html and/or text has been printed to standard out.

For more information and usage: http://php.net/manual/en/function.header.php

I see in your code that you echo() out some text in case of error or success. Don't do that: you can't. You can only redirect OR show the text. If you show the text you'll then fail to redirect.

In addition to the other answers, you can use this less-known method to grab elements of a certain parent like so,

$('child', 'parent');

In your case, that would be

if ($(event.target, 'div#hello')[0]) console.log(`${event.target.tagName} is an offspring of div#hello`);

Note the use of commas between the child and parent and their separate quotation marks. If they were surrounded by the same quotes

$('child, parent');

you'd have an object containing both objects, regardless of whether they exist in their document trees.

You can write your query like this.

var query = from t1 in myTABLE1List // List<TABLE_1>
            join t2 in myTABLE1List
               on t1.ColumnA equals t2.ColumnA
               and t1.ColumnB equals t2.ColumnA

If you want to compare your column with multiple columns.

You can use getComputedStyle().

var element = document.getElementById('image_1'),
    style = window.getComputedStyle(element),
    top = style.getPropertyValue('top');

jsFiddle.

Cut has a --complement flag that makes it easy (and fast) to delete columns. The resulting syntax is analogous with what you want to do -- making the solution easier to read/understand. Complement also works for the case where you would like to delete non-contiguous columns.

$ foo='1 2 3 %s 5 6 7'
$ echo "$foo" | cut --complement -d' ' -f1-3
%s 5 6 7
$

Just adding another idea you could use a child selector to get immediate children

document.querySelectorAll(".parent > .child1");

should return all the immediate children with class .child1

I found this useful command:

npm rebuild node-sass

From the rebuild documentation:

This is useful when you install a new version of node (or switch node versions), and must recompile all your C++ addons with the new node.js binary.

We have found that adding the Apptentive cocoa pod to an existing Xcode project may potentially not include some of our required frameworks.

Check your linker flags:

Target > Build Settings > Other Linker Flags 

You should see -lApptentiveConnect listed as a linker flag:

... -ObjC -lApptentiveConnect ... 

You should also see our required Frameworks listed:

• Accelerate
• CoreData
• CoreText
• CoreGraphics
• CoreTelephony
• Foundation
• QuartzCore
• StoreKit
• SystemConfiguration

• UIKit

  -ObjC -lApptentiveConnect -framework Accelerate -framework CoreData -framework CoreGraphics -framework CoreText -framework Foundation -framework QuartzCore -framework SystemConfiguration -framework UIKit -framework CoreTelephony -framework StoreKit  

Use below code to convert String Date to Epoc Timestamp. Note : - Your input Date format should match with SimpleDateFormat.

String inputDateInString= "8/15/2017 12:00:00 AM";
SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyy hh:mm:ss");

Date parsedDate = dateFormat.parse("inputDateInString");

Timestamp timestamp = new java.sql.Timestamp(parsedDate.getTime());

System.out.println("Timestamp "+ timestamp.getTime());

Just set this extra line in catalina.bat file

LINE NO AROUND: 143

set "CATALINA_OPTS=-Xms512m -Xmx512m"

And restart Tomcat service

It means it matches to every p element which is immediately adjacent

I will leave this here as a possible fix, worked for me at least and might help others. Pretty sure this would be a linux only fix.

I decided to not go with the pip install and go with the github version (option one on the installation guide).

Instead of placing the copied docker-compose directory into /usr/local/bin/docker-compose from the curl/github command, I went with /usr/bin/docker-compose which is the location of Docker itself and will force the program to run in root. So it works in root and sudo but now won't work without sudo so the opposite effect which is what you want to run it as a user anyways.

I met the same problem and for finding all validation errors and displaying them, I wrote next method:

getFormValidationErrors() {
  Object.keys(this.productForm.controls).forEach(key => {

  const controlErrors: ValidationErrors = this.productForm.get(key).errors;
  if (controlErrors != null) {
        Object.keys(controlErrors).forEach(keyError => {
          console.log('Key control: ' + key + ', keyError: ' + keyError + ', err value: ', controlErrors[keyError]);
        });
      }
    });
  }

Form name productForm should be changed to yours.

It works in next way: we get all our controls from form in format {[p: string]: AbstractControl} and iterate by each error key, for get details of error. It skips null error values.

It also can be changed for displaying validation errors on the template view, just replace console.log(..) to what you need.

Put your JTable inside a JScrollPane. Try this:

add(new JScrollPane(scrTbl));

Use ViewChild with #localvariable as shown here,

<textarea  #someVar  id="tasknote"
                  name="tasknote"
                  [(ngModel)]="taskNote"
                  placeholder="{{ notePlaceholder }}"
                  style="background-color: pink"
                  (blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }} 

</textarea>

In component,

OLDEST Way

import {ElementRef} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

ngAfterViewInit()
{
   this.el.nativeElement.focus();
}

OLD Way

import {ElementRef} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

constructor(private rd: Renderer) {}
ngAfterViewInit() {
    this.rd.invokeElementMethod(this.el.nativeElement,'focus');
}

NEW Way

Please note from Angular v4.0.0-rc.3 (2017-03-10) few things have been changed. Since Angular team will deprecate invokeElementMethod, above code no longer can be used.

BREAKING CHANGES

since 4.0 rc.1:

rename RendererV2 to Renderer2
rename RendererTypeV2 to RendererType2
rename RendererFactoryV2 to RendererFactory2

import {ElementRef,Renderer2} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

constructor(private rd: Renderer2) {}

ngAfterViewInit() {
      console.log(this.rd); 
      this.el.nativeElement.focus();      //<<<=====same as oldest way
}

console.log(this.rd) will give you following methods and you can see now invokeElementMethod is not there. Attaching img as yet it is not documented.

NOTE: You can use following methods of Rendere2 with/without ViewChild variable to do so many things.

 <?php if (date("H") < "12" && date("H")>"6") { ?>
   src="<?php bloginfo('template_url'); ?>/images/img/morning.gif" 
 <?php } elseif (date("H") > "12" && date("H")<"17") { ?>
 src="<?php bloginfo('template_url'); ?>/images/img/noon.gif" 
  <?php } elseif (date("H") > "17" && date("H")<"21") { ?>
   src="<?php bloginfo('template_url'); ?>/images/img/evening.gif" 
  <?php } elseif (date("H") > "21" && date("H")<"24") { ?>
  src="<?php bloginfo('template_url'); ?>/images/img/night.gif" 
  <?php }else { ?>
  src="<?php bloginfo('template_url'); ?>/images/img/mid_night.gif" 
  <?php } ?>

You've accidentally set "Pause on Exceptions" to all/uncaught exceptions.

Go to the "Sources" tab. At the bottom toolbar, toggle the button that looks like the pause symbol surrounded by a circle (4th button from the left) until the color of the circle turns black to turn it off.

this is actually pretty easily done. You're almost there, doing what you've done with background-position: right center;. What is actually needed in this case is something very much like that. Let's convert these to percentages. We know that center=50%, so that's easy enough. Now, in order to get the padding you wanted, you need to position the background like so: background-position: 99% 50%.

The second, and more effective way of going about this, is to use the same background-position idea, and just use background-position: 400px (width of parent) 50%;. Of course, this method requires a static width, but will give you the same thing every time.

Method 1 (99% 50%)
Method 2 (400px 50%)

Centering the child elements in a div. It works for all screen sizes

#parent {
    padding: 5% 0;
}

#child {
    padding: 10% 0;
}

<div id="parent">
    <div id="child">Content here</div>
</div>

If you want to run a script to a database:

mysql -u user -p data_base_name_here < db.sql

Use the Chr or ChrW function, Chr(charNumber).

if you are using boolean variable to bind the radio button. please refer below sample code

<div ng-repeat="book in books"> 
<input type="radio" ng-checked="book.selected"  
ng-click="function($event)">                        
</div>

This worked for me on win replace REL_PATH_TO_FILE with the relative path to the file to remove Removing sensitive data from a repository The docs say full path - but that errored for me -so I tried rel path and it worked.

<from the repo dir>git filter-branch --force --index-filter "git rm --cached --ignore-unmatch REL_PATH_TO_FILE" --prune-empty --tag-name-filter cat -- --all

The right is php_memcache.dll. In my case i was using lib compiled with vc9 instead of vc6 compiler. In apatche error logs i got something like:

PHP Startup: sqlanywhere: Unable to initialize module Module compiled with build ID=API20090626, TS,VC9 PHP compiled with build ID=API20090626, TS,VC6 These options need to match

Check if you have same log and try downloading different dll that are compiled with different compiler.

Operators first() and take(1) aren't the same.

The first() operator takes an optional predicate function and emits an error notification when no value matched when the source completed.

For example this will emit an error:

import { EMPTY, range } from 'rxjs';
import { first, take } from 'rxjs/operators';

EMPTY.pipe(
  first(),
).subscribe(console.log, err => console.log('Error', err));

... as well as this:

range(1, 5).pipe(
  first(val => val > 6),
).subscribe(console.log, err => console.log('Error', err));

While this will match the first value emitted:

range(1, 5).pipe(
  first(),
).subscribe(console.log, err => console.log('Error', err));

On the other hand take(1) just takes the first value and completes. No further logic is involved.

range(1, 5).pipe(
  take(1),
).subscribe(console.log, err => console.log('Error', err));

Then with empty source Observable it won't emit any error:

EMPTY.pipe(
  take(1),
).subscribe(console.log, err => console.log('Error', err));

Jan 2019: Updated for RxJS 6

You can also use reduce method:

>>> myList = [3, 5, 4, 9]
>>> myTotal = reduce(lambda x,y: x+y, myList)
>>> myTotal
21

Furthermore, you can modify the lambda function to do other operations on your list.

Try this:

foreach($samplearr as $key => $item){
  print "<tr><td>" 
      . $key 
      . "</td><td>"  
      . $item['value1'] 
      . "</td><td>" 
      . $item['value2'] 
      . "</td></tr>";
}

If left an expressions tab in my IDE open which was making a hibernate get call on the object causing this exception. I was trying to delete this same object. Also I had a breakpoint on the delete call which seems to be necessary to get this error to happen. Simply making another expressions tab to be the front tab or changing the setting so that the ide does not stop on breakpoints solved this problem.

Path.GetTempFileName() will create a uniquly named empty file and return the path to it.

If you want to control the path but get a random file name you can use GetRandomFileName to just return a file name string and use it with Create

For example:

string fileName=Path.GetRandomFileName();
File.Create("custom\\path\\" + fileName);

<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>

<h:outputText value="Table Size = #{fn:length(SystemBean.list)}"/>

On screen it displays the Table size

Example: Table Size = 5

Use a query terminator string and set this in the options of your SQL client application. I use ; as the query terminator.

Your SQL would look like this;

UPDATE table SET ID = 111111259 WHERE ID = 2555;
UPDATE table SET ID = 111111261 WHERE ID = 2724;
UPDATE table SET ID = 111111263 WHERE ID = 2021;
UPDATE table SET ID = 111111264 WHERE ID = 2017;

This will allow you to do a Ctrl + A and run all the lines at once.

The string terminator tells the SQL client that the update statement is finished and to go to the next line and process the next statement.

Hope that helps

I am sorry everyone that this is the solution the true one where you dont have to actually set the padding.

http://jsfiddle.net/techsin/TyXRY/1/

What i have done...

• Applied two gradients on background with both having one start and end color. Instead of using solid color. Reason being that you can't have two solid colors for one background.
• Then applied different background-clip property to each.
• thus making one color extend to content box and other to border, revealing the padding.

Clever if i say so to myself.

div {
    padding: 35px;
    background-image:
      linear-gradient(to bottom,
        rgba(240, 255, 40, 1) 0%,
        rgba(240, 255, 40, 1) 100%),
      linear-gradient(to bottom,
        rgba(240, 40, 40, 1) 0%,
        rgba(240, 40, 40, 1) 100%);
    background-clip: content-box, padding-box;
}

The best way to do that programmatically is using the next method:

public static DigitsKeyListener getInstance (boolean sign, boolean decimal) 

Returns a DigitsKeyListener that accepts the digits 0 through 9, plus the minus sign (only at the beginning) and/or decimal point (only one per field) if specified.

This solve the problem about the many '.' in EditText

editText.setKeyListener(DigitsKeyListener.getInstance(true,true)); // decimals and positive/negative numbers. 

editText.setKeyListener(DigitsKeyListener.getInstance(false,true)); // positive decimals numbers. 

editText.setKeyListener(DigitsKeyListener.getInstance(false,false)); // positive integer numbers.

editText.setKeyListener(DigitsKeyListener.getInstance(true,false)); // positive/negative integer numbers.

I have been successfull at impersonating users in another domain, but only with a trust set up between the 2 domains.

var token = IntPtr.Zero;
var result = LogonUser(userID, domain, password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref token);
if (result)
{
    return WindowsIdentity.Impersonate(token);
}

My main problem is that I really don't know how to implement multiprocessing.queue correctly, you cannot really instantiate the object for each process since they will be separate queues, how do you make sure that all processes relate to a shared queue (or in this case, queues)

This is a simple example of a reader and writer sharing a single queue... The writer sends a bunch of integers to the reader; when the writer runs out of numbers, it sends 'DONE', which lets the reader know to break out of the read loop.

from multiprocessing import Process, Queue
import time
import sys

def reader_proc(queue):
    ## Read from the queue; this will be spawned as a separate Process
    while True:
        msg = queue.get()         # Read from the queue and do nothing
        if (msg == 'DONE'):
            break

def writer(count, queue):
    ## Write to the queue
    for ii in range(0, count):
        queue.put(ii)             # Write 'count' numbers into the queue
    queue.put('DONE')

if __name__=='__main__':
    pqueue = Queue() # writer() writes to pqueue from _this_ process
    for count in [10**4, 10**5, 10**6]:             
        ### reader_proc() reads from pqueue as a separate process
        reader_p = Process(target=reader_proc, args=((pqueue),))
        reader_p.daemon = True
        reader_p.start()        # Launch reader_proc() as a separate python process

        _start = time.time()
        writer(count, pqueue)    # Send a lot of stuff to reader()
        reader_p.join()         # Wait for the reader to finish
        print("Sending {0} numbers to Queue() took {1} seconds".format(count, 
            (time.time() - _start)))

An enumeration is something of an inverse-array. What I believe you want is this:

const char * Week[] = { "", "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };  // The blank string at the beginning is so that Sunday is 1 instead of 0.
cout << "Today is " << Week[2] << ", enjoy!";  // Or whatever you'de like to do with it.

In Fujimoto Youichi's example test01 is a container, whereas test02 is an image.

Before doing docker run you can remove the original container and then assign the container the same name again:

$ docker stop container01
$ docker commit container01 image01
$ docker rm container01
$ docker run -d -P --name container01 image01

(Using -P to expose ports to random ports rather than manually assigning).

You can't mix tab and spaces for identation. Best practice is to convert all tabs to spaces.

How to fix this? Well just delete all the spaces/tabs before each line and convert them uniformly either to tabs OR spaces, but don't mix. Best solution: enable in your Editor the option to convert automagically any tabs to spaces.

Also be aware that your actual problem may lie in the lines before this block, and python throws the error here, because of a leading invalid indentation which doesn't match the following identations!

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

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

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

Here is a guide to JSZIP to create ZIP files by JavaScript. To download files you need to have filesaver.js, You can include those libraries by:

<script src="https://cdnjs.cloudflare.com/ajax/libs/jszip/3.1.4/jszip.min.js"  type="text/javascript"></script>
<script type="text/javascript" src="https://fastcdn.org/FileSaver.js/1.1.20151003/FileSaver.js" ></script>

Now copy this code and this code will download a zip file with a file hello.txt having content Hello World. If everything thing works fine, this will download a file.

<script type="text/javascript">
    var zip = new JSZip();
    zip.file("Hello.txt", "Hello World\n");
    zip.generateAsync({type:"blob"})
    .then(function(content) {
        // see FileSaver.js
        saveAs(content, "file.zip");
    });
</script>

Now let's get in to deeper. Create an instance of JSZip.

var zip = new JSZip();

Add a file with a Hello World text:

zip.file("hello.txt", "Hello World\n");

Download the filie with name archive.zip

zip.generateAsync({type:"blob"}).then(function(zip) {
    saveAs(zip, "archive.zip");
});

The Unix Date command will display in epoch time

the command is

Since MySQL (8.0.16) and MariaDB (10.2.1) both implemented the CHECK constraint, I would now use

bool_val TINYINT CHECK(bool_val IN(0,1))

You will only be able to store 0, 1 or NULL, as well as values which can be converted to 0 or 1 without errors like '1', 0x00, b'1' or TRUE/FALSE.

If you don't want to permit NULLs, add the NOT NULL option

bool_val TINYINT NOT NULL CHECK(bool_val IN(0,1))

Note that there is virtually no difference if you use TINYINT, TINYINT(1) or TINYINT(123).

If you want your schema to be upwards compatible, you can also use BOOL or BOOLEAN

bool_val BOOL CHECK(bool_val IN(TRUE,FALSE))

AD registers Service Location (SRV) resource records in its DNS server which you can query to get the port and the hostname of the responsible LDAP server in your domain.

Just try this on the command-line:

C:\> nslookup 
> set types=all
> _ldap._tcp.<<your.AD.domain>>
_ldap._tcp.<<your.AD.domain>>  SRV service location:
      priority       = 0
      weight         = 100
      port           = 389
      svr hostname   = <<ldap.hostname>>.<<your.AD.domain>>

(provided that your nameserver is the AD nameserver which should be the case for the AD to function properly)

Please see Active Directory SRV Records and Windows 2000 DNS white paper for more information.

From Google OAuth2.0 for Client documentation,

• expires_in -- The number of seconds left before the token becomes invalid.

A better approach is:

int x = rand.nextInt(max - min + 1) + min;

Your formula generates numbers between min and min + max.

Random random = new Random(1234567);
int min = 5;
int max = 20;
while (true) {
    int x = (int)(Math.random() * max) + min;
    System.out.println(x);
    if (x < min || x >= max) { break; }
}       

Result:

10
16

21 // Oops!!

Tables are odd elements. Unlike divs they have special rules. Add cellspacing and cellpadding attributes, set to 0, and it should fix the problem.

<table id="page" width="100%" border="0" cellspacing="0" cellpadding="0">

Since FFT is symmetric over it's centre, half the values are just enough.

import numpy as np
import matplotlib.pyplot as plt

fs = 30.0
t = np.arange(0,10,1/fs)
x = np.cos(2*np.pi*10*t)

xF = np.fft.fft(x)
N = len(xF)
xF = xF[0:N/2]
fr = np.linspace(0,fs/2,N/2)

plt.ion()
plt.plot(fr,abs(xF)**2)

It's difficult to think of a specific occasion when you'd need this type of flexible structure, perhaps in a message protocol where you would be sending different sizes of messages, but even then there are probably better and more programmer friendly alternatives.

Unions are a bit like variant types in other languages - they can only hold one thing at a time, but that thing could be an int, a float etc. depending on how you declare it.

For example:

typedef union MyUnion MYUNION;
union MyUnion
{
   int MyInt;
   float MyFloat;
};

MyUnion will only contain an int OR a float, depending on which you most recently set. So doing this:

MYUNION u;
u.MyInt = 10;

u now holds an int equal to 10;

u.MyFloat = 1.0;

u now holds a float equal to 1.0. It no longer holds an int. Obviously now if you try and do printf("MyInt=%d", u.MyInt); then you're probably going to get an error, though I'm unsure of the specific behaviour.

The size of the union is dictated by the size of its largest field, in this case the float.

In bash, contrary to [, [[ prevents word splitting of variable values.

Most updated solution

If you are using Javascript, the best solution that I came up with is using match instead of exec method. Then, iterate matches and remove the delimiters with the result of the first group using $1

const text = "This is a test string [more or less], [more] and [less]";
const regex = /\[(.*?)\]/gi;
const resultMatchGroup = text.match(regex); // [ '[more or less]', '[more]', '[less]' ]
const desiredRes = resultMatchGroup.map(match => match.replace(regex, "$1"))
console.log("desiredRes", desiredRes); // [ 'more or less', 'more', 'less' ]

As you can see, this is useful for multiple delimiters in the text as well

Your answer is right in the docs:

Body padding required

The fixed navbar will overlay your other content, unless you add padding to the top of the <body>. Try out your own values or use our snippet below. Tip: By default, the navbar is 50px high.

body { padding-top: 70px; }

Make sure to include this after the core Bootstrap CSS.

and in the Bootstrap 4 docs...

Fixed navbars use position: fixed, meaning they’re pulled from the normal flow of the DOM and may require custom CSS (e.g., padding-top on the ) to prevent overlap with other elements.

1) Others (especially dirkgently) have noted that buffer needs to be allocated some memory space. For smallish values of N (say, N <= 4096), you can also allocate it on the stack:

#define BUFFER_SIZE 4096
char buffer[BUFFER_SIZE]

This saves you the worry of ensuring that you delete[] the buffer should an exception be thrown.

But remember that stacks are finite in size (so are heaps, but stacks are finiter), so you don't want to put too much there.

2) On a -1 return code, you should not simply return immediately (throwing an exception immediately is even more sketchy.) There are certain normal conditions that you need to handle, if your code is to be anything more than a short homework assignment. For example, EAGAIN may be returned in errno if no data is currently available on a non-blocking socket. Have a look at the man page for read(2).

I had that problem too.

Try using Server.Transfer instead of Response.Redirect

Worked for me.

Can't add a comment to the solution but that didn't work for me. The solution that worked for me was to use:

var des = (MyClass)Newtonsoft.Json.JsonConvert.DeserializeObject(response, typeof(MyClass)); 
return des.data.Count.ToString();

Fwiw, I had this problem when running check_nrpe on a system that had the zenoss monitoring system installed. To add to the confusion, it worked fine as root user but not as zenoss user.

I found out that the zenoss user had an LD_LIBRARY_PATH that caused it to use zenoss libraries, which issue these warnings. Ie:

root@monitoring:$ echo $LD_LIBRARY_PATH

su - zenoss
zenoss@monitoring:/root$ echo $LD_LIBRARY_PATH
/usr/local/zenoss/python/lib:/usr/local/zenoss/mysql/lib:/usr/local/zenoss/zenoss/lib:/usr/local/zenoss/common/lib::
zenoss@monitoring:/root$ /usr/lib/nagios/plugins/check_nrpe -H 192.168.61.61 -p 6969 -c check_mq
/usr/lib/nagios/plugins/check_nrpe: /usr/local/zenoss/common/lib/libcrypto.so.0.9.8: no version information available (required by /usr/lib/libssl.so.0.9.8)
(...)
zenoss@monitoring:/root$ LD_LIBRARY_PATH= /usr/lib/nagios/plugins/check_nrpe -H 192.168.61.61 -p 6969 -c check_mq
(...)

So anyway, what I'm trying to say: check your variables like LD_LIBRARY_PATH, LD_PRELOAD etc as well.

This code works great nice

use this class for root view:

public class KeyboardConstraintLayout extends ConstraintLayout {

private KeyboardListener keyboardListener;
private EditText targetEditText;
private int minKeyboardHeight;
private boolean isShow;

public KeyboardConstraintLayout(Context context) {
    super(context);
    minKeyboardHeight = getResources().getDimensionPixelSize(R.dimen.keyboard_min_height); //128dp
}

public KeyboardConstraintLayout(Context context, AttributeSet attrs) {
    super(context, attrs);
    minKeyboardHeight = getResources().getDimensionPixelSize(R.dimen.keyboard_min_height); // 128dp
}

public KeyboardConstraintLayout(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
    minKeyboardHeight = getResources().getDimensionPixelSize(R.dimen.keyboard_min_height); // 128dp
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    if (!isInEditMode()) {
        Activity activity = (Activity) getContext();
        @SuppressLint("DrawAllocation")
        Rect rect = new Rect();
        getWindowVisibleDisplayFrame(rect);

        int statusBarHeight = rect.top;
        int keyboardHeight = activity.getWindowManager().getDefaultDisplay().getHeight() - (rect.bottom - rect.top) - statusBarHeight;

        if (keyboardListener != null && targetEditText != null && targetEditText.isFocused()) {
            if (keyboardHeight > minKeyboardHeight) {
                if (!isShow) {
                    isShow = true;
                    keyboardListener.onKeyboardVisibility(true);
                }
            }else {
                if (isShow) {
                    isShow = false;
                    keyboardListener.onKeyboardVisibility(false);
                }
            }
        }
    }
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

public boolean isShowKeyboard() {
    return isShow;
}

public void setKeyboardListener(EditText targetEditText, KeyboardListener keyboardListener) {
    this.targetEditText = targetEditText;
    this.keyboardListener = keyboardListener;
}

public interface KeyboardListener {
    void onKeyboardVisibility (boolean isVisible);
}

}

and set keyboard listener in activity or fragment:

        rootLayout.setKeyboardListener(targetEditText, new KeyboardConstraintLayout.KeyboardListener() {
        @Override
        public void onKeyboardVisibility(boolean isVisible) {

        }
    });

I dont think adding dual functions inside the toggle function works for a registered click event (Unless I'm missing something)

For example:

$('.btnName').click(function() {
 top.$('#panel').toggle(function() {
   $(this).animate({ 
     // style change
   }, 500);
   },
   function() {
   $(this).animate({ 
     // style change back
   }, 500);
 });

window.location.reload(true) seems to have been deprecated by the HTML5 standard. One way to do this without using query strings is to use the Clear-Site-Data header, which seems to being standardized.

I wanted a way to do this without using an extra module. First turn list to string, then append to an array:

dataset_list = ''.join(input_list)
dataset_array = []
for item in dataset_list.split(';'): # comma, or other
    dataset_array.append(item)

#define ID_LEN 5
char **orderedIds;
int i;
int variableNumberOfElements = 5; /* Hard coded here */

orderedIds = (char **)malloc(variableNumberOfElements * (ID_LEN + 1) * sizeof(char));

..

Other answers posted here for this question did not work for me using the latest Visual Studio 2017 Enterprise edition (as of 2018-09-18).

Instead, I used this method:

1. Close all but one instance of Visual Studio.
2. In the running instance, access the menu Tools->Extensions and Updates.
3. In that dialog, choose Online->Visual Studio Marketplace->Tools->Setup & Deployment.
4. From the list that appears, select Microsoft Visual Studio 2017 Installer Projects.

Once installed, close and restart Visual Studio. Go to File->New Project and search for the word Installer. You'll know you have the correct templates installed if you see a list that looks something like this:

What you need to do is to call pthread_mutex_lock to secure a mutex, like this:

pthread_mutex_lock(&mutex);

Once you do this, any other calls to pthread_mutex_lock(mutex) will not return until you call pthread_mutex_unlock in this thread. So if you try to call pthread_create, you will be able to create a new thread, and that thread will be able to (incorrectly) use the shared resource. You should call pthread_mutex_lock from within your fooAPI function, and that will cause the function to wait until the shared resource is available.

So you would have something like this:

#include <pthread.h>
#include <stdio.h>

int sharedResource = 0;
pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER;

void* fooAPI(void* param)
{
    pthread_mutex_lock(&mutex);
    printf("Changing the shared resource now.\n");
    sharedResource = 42;
    pthread_mutex_unlock(&mutex);
    return 0;
}

int main()
{
    pthread_t thread;

    // Really not locking for any reason other than to make the point.
    pthread_mutex_lock(&mutex);
    pthread_create(&thread, NULL, fooAPI, NULL);
    sleep(1);
    pthread_mutex_unlock(&mutex);

    // Now we need to lock to use the shared resource.
    pthread_mutex_lock(&mutex);
    printf("%d\n", sharedResource);
    pthread_mutex_unlock(&mutex);
}

Edit: Using resources across processes follows this same basic approach, but you need to map the memory into your other process. Here's an example using shmem:

#include <stdio.h>
#include <unistd.h>
#include <sys/file.h>
#include <sys/mman.h>
#include <sys/wait.h>

struct shared {
    pthread_mutex_t mutex;
    int sharedResource;
};

int main()
{
    int fd = shm_open("/foo", O_CREAT | O_TRUNC | O_RDWR, 0600);
    ftruncate(fd, sizeof(struct shared));

    struct shared *p = (struct shared*)mmap(0, sizeof(struct shared),
        PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0);

    p->sharedResource = 0;

    // Make sure it can be shared across processes
    pthread_mutexattr_t shared;
    pthread_mutexattr_init(&shared);
    pthread_mutexattr_setpshared(&shared, PTHREAD_PROCESS_SHARED);

    pthread_mutex_init(&(p->mutex), &shared);

    int i;
    for (i = 0; i < 100; i++) {
        pthread_mutex_lock(&(p->mutex));
        printf("%d\n", p->sharedResource);
        pthread_mutex_unlock(&(p->mutex));
        sleep(1);
    }

    munmap(p, sizeof(struct shared*));
    shm_unlink("/foo");
}

Writing the program to make changes to p->sharedResource is left as an exercise for the reader. :-)

Forgot to note, by the way, that the mutex has to have the PTHREAD_PROCESS_SHARED attribute set, so that pthreads will work across processes.

This is because pushd is a builtin function in bash. So it is not related to the PATH variable and also it is not supported by /bin/sh (which is used by default by make. You can change that by setting SHELL (although it will not work directly (test1)).

You can instead run all the commands through bash -c "...". That will make the commands, including pushd/popd, run in a bash environment (test2).

SHELL = /bin/bash

test1:
        @echo before
        @pwd
        @pushd /tmp
        @echo in /tmp
        @pwd
        @popd
        @echo after
        @pwd

test2:
        @/bin/bash -c "echo before;\
        pwd; \
        pushd /tmp; \
        echo in /tmp; \
        pwd; \
        popd; \
        echo after; \
        pwd;"

When running make test1 and make test2 it gives the following:

prompt>make test1
before
/download/2011/03_mar
make: pushd: Command not found
make: *** [test1] Error 127
prompt>make test2
before
/download/2011/03_mar
/tmp /download/2011/03_mar
in /tmp
/tmp
/download/2011/03_mar
after
/download/2011/03_mar
prompt>

For test1, even though bash is used as a shell, each command/line in the rule is run by itself, so the pushd command is run in a different shell than the popd.

You can try using your function and using a timeout waiting until the jQuery object is loaded

Code:

document.onload=function(){
    var fileref=document.createElement('script');
    fileref.setAttribute("type","text/javascript");
    fileref.setAttribute("src", 'http://code.jquery.com/jquery-1.7.2.min.js');
    document.getElementsByTagName("head")[0].appendChild(fileref);
    waitForjQuery();
}

function waitForjQuery() {
    if (typeof jQuery != 'undefined') {
        // do some stuff
    } else {
        window.setTimeout(function () { waitForjQuery(); }, 100);
    }
}

I recommend

$('#myTable > tbody:first').append('<tr>...</tr><tr>...</tr>'); 

as opposed to

$('#myTable > tbody:last').append('<tr>...</tr><tr>...</tr>'); 

The first and last keywords work on the first or last tag to be started, not closed. Therefore, this plays nicer with nested tables, if you don't want the nested table to be changed, but instead add to the overall table. At least, this is what I found.

<table id=myTable>
  <tbody id=first>
    <tr><td>
      <table id=myNestedTable>
        <tbody id=last>
        </tbody>
      </table>
    </td></tr>
  </tbody>
</table>

To change the stacking order for series in charts under Excel for Mac 2011:

1. select the chart,
2. select the series (easiest under Ribbon>Chart Layout>Current Selection),
3. click Chart Layout>Format Selection or Menu>Format>Data Series …,
4. on popup menu Format Data Series click Order, then click individual series and click Move Up or Move Down buttons to adjust the stacking order on the Axis for the subject series. This changes the order for the plot and for the legend, but may not change the order number in the Series formula.

I had a three series plot on the secondary axis, and the series I wanted on top was stuck on the bottom in defiance of the Move Up and Move Down buttons. It happened to be formatted as markers only. I inserted a line, and presto(!), I could change its order in the plot. Later I could remove the line and sometimes it could still be ordered, but sometimes not.

Binding RelativeSource={
    RelativeSource Mode=FindAncestor, AncestorType={x:Type ItemType}
}
...

The default attribute of RelativeSource is the Mode property. A complete set of valid values is given here (from MSDN):

• PreviousData Allows you to bind the previous data item (not that control that contains the data item) in the list of data items being displayed.

• TemplatedParent Refers to the element to which the template (in which the data-bound element exists) is applied. This is similar to setting a TemplateBindingExtension and is only applicable if the Binding is within a template.

• Self Refers to the element on which you are setting the binding and allows you to bind one property of that element to another property on the same element.

• FindAncestor Refers to the ancestor in the parent chain of the data-bound element. You can use this to bind to an ancestor of a specific type or its subclasses. This is the mode you use if you want to specify AncestorType and/or AncestorLevel.

I am not sure since I am not an Oracle user, but I assume that the difference lies when you use multi-byte character sets such as Unicode (UTF-16/32). In this case, 11 Bytes could account for less than 11 characters.

Also those field types might be treated differently in regard to accented characters or case, for example 'binaryField(ete) = "été"' will not match while 'charField(ete) = "été"' might (again not sure about Oracle).

CSS3 has a pseudo-class called :not()

input:not([type='checkbox']) {    
    visibility: hidden;
}

<p>If <code>:not()</code> is supported, you'll only see the checkbox.</p>
                                      
<ul>
  <li>text: (<input type="text">)</li>  
  <li>password (<input type="password">)</li>       
  <li>checkbox (<input type="checkbox">)</li> 
 </ul>

Multiple selectors

As Vincent mentioned, it's possible to string multiple :not()s together:

input:not([type='checkbox']):not([type='submit'])

CSS4, which is supported in many of the latest browser releases, allows multiple selectors in a :not()

input:not([type='checkbox'],[type='submit'])

Legacy support

All modern browsers support the CSS3 syntax. At the time this question was asked, we needed a fall-back for IE7 and IE8. One option was to use a polyfill like IE9.js. Another was to exploit the cascade in CSS:

input {
   // styles for most inputs
}   

input[type=checkbox] {
  // revert back to the original style
} 

input.checkbox {
  // for completeness, this would have worked even in IE3!
} 

If you use dplyr package you can do:

library(dplyr)
filter(df, aged <= laclen)

File -> Export -> Web -> WAR file

OR in Kepler follow as shown below :

Its seems that server is not running properly so ensure that with terminal by

telnet ip port

example

telnet localhost 8069

It will return connected to localhost so it indicates that there is no problem with the connection Else it will return Connection refused it indicates that there is problem with the connection

try:

SELECT CAST( CAST([field] AS VARBINARY) AS varchar) 

You can read that here

If you use

{{<br />}}

it'll be escaped. If you want raw html, you gotta use

{{{<br />}}}

EDIT (Feb 5 2017): As @hitautodestruct points out, in vue 2 you should use v-html instead of triple curly braces.

body
{
    position: fixed;  /*fixes the image in background*/
    top: 0; /*fixes the image at top*/
    left: 0; /*fixes the image at left*/
    min-width: 100%; /*fixes the image width to 100% of screen*/
    min-height: 100%; /*fixes the image height to 100% of screen*/
}

Once I faced with the issue when I did not know which the element currently stored in my variable (svg or html) but I needed to get it width and height. I created this function and want to share it:

function computeDimensions(selection) {
  var dimensions = null;
  var node = selection.node();

  if (node instanceof SVGGraphicsElement) { // check if node is svg element
    dimensions = node.getBBox();
  } else { // else is html element
    dimensions = node.getBoundingClientRect();
  }
  console.log(dimensions);
  return dimensions;
}

Little demo in the hidden snippet below. We handle click on the blue div and on the red svg circle with the same function.

var svg = d3.select('svg')
  .attr('width', 50)
  .attr('height', 50);

function computeDimensions(selection) {
    var dimensions = null;
  var node = selection.node();

  if (node instanceof SVGElement) {
    dimensions = node.getBBox();
  } else {
    dimensions = node.getBoundingClientRect();
  }
  console.clear();
  console.log(dimensions);
  return dimensions;
}

var circle = svg
    .append("circle")
    .attr("r", 20)
    .attr("cx", 30)
    .attr("cy", 30)
    .attr("fill", "red")
    .on("click", function() { computeDimensions(circle); });
    
var div = d3.selectAll("div").on("click", function() { computeDimensions(div) });

* {
  margin: 0;
  padding: 0;
  border: 0;
}

body {
  background: #ffd;
}

.div {
  display: inline-block;
  background-color: blue;
  margin-right: 30px;
  width: 30px;
  height: 30px;
}

<h3>
  Click on blue div block or svg circle

Just use the following command

git show a2c25061

or (the exact equivalent):

git log -p -1 a2c25061

Adding the correct doctype declaration and avoiding the XML prolog should be enough to avoid quirks mode.

Google have made this easier in SDK 21. Now we have attributes for specifying the thumb tint colors:

Complete guide

-----------------With angular-cli--------------------------

1. Update CLI globally and locally

1. Using NPM ( make sure that you have node version 8+ )

   npm uninstall -g @angular/cli npm cache clean npm install -g @angular/cli@latest npm i @angular/cli --save

2. Using Yarn

   yarn remove @angular/cli yarn global add @angular/cli yarn add @angular/cli

2.Update dependencies

ng update @angular/cli
ng update @angular/core
ng update @angular/material
ng update rxjs

Angular 6 now depends on TypeScript 2.7 and RxJS 6

Normally that would mean that you have to update your code everywhere RxJS imports and operators are used, but thankfully there’s a package that takes care of most of the heavy lifting:

npm i -g rxjs-tslint 

//or using yarn

yarn global add rxjs-tslint

Then you can run rxjs-5-to-6-migrate

rxjs-5-to-6-migrate -p src/tsconfig.app.json

finally remove rxjs-compat

npm uninstall rxjs-compat

// or using Yarn

yarn remove rxjs-compat

Refer to this link https://alligator.io/angular/angular-6/

-------------------Without angular-cli-------------------------

So you have to manually update your package.json file.

Then run

 npm update
 npm install --save rxjs-compat
 npm i -g rxjs-tslint
 rxjs-5-to-6-migrate -p src/tsconfig.app.json

Create Learning Table:

CREATE TABLE "public"."learning" (
    "api_id" int4 DEFAULT nextval('share_api_api_id_seq'::regclass) NOT NULL,
    "title" varchar(255) COLLATE "default"
);

Insert Data Learning Table:

INSERT INTO "public"."learning" VALUES ('1', 'Google AI-01');
INSERT INTO "public"."learning" VALUES ('2', 'Google AI-02');
INSERT INTO "public"."learning" VALUES ('3', 'Google AI-01');

Step: 01

CREATE OR REPLACE FUNCTION get_all (pattern VARCHAR) RETURNS TABLE (
        learn_id INT,
        learn_title VARCHAR
) AS $$
BEGIN
    RETURN QUERY SELECT
        api_id,
        title
    FROM
        learning
    WHERE
        title = pattern ;
END ; $$ LANGUAGE 'plpgsql';

Step: 02

SELECT * FROM get_all('Google AI-01');

Step: 03

DROP FUNCTION get_all();

Found a nice solution in another Stackoverflow post (using only standard libraries + dealing with jpg as well): JohnTESlade answer

And another solution (the quick way) for those who can afford running 'file' command within python, run:

import os
info = os.popen("file foo.jpg").read()
print info

Output:

foo.jpg: JPEG image data...density 28x28, segment length 16, baseline, precision 8, 352x198, frames 3

All you gotta do now is to format the output to capture the dimensions. 352x198 in my case.

Simple. Just instantiate your entity, set it to an object and pass it to your view in your controller.

Entity

VehicleInfoEntities db = new VehicleInfoEntities();

Stored Procedure

dbo.prcGetMakes()

or

you can add any parameters in your stored procedure inside the brackets ()

dbo.prcGetMakes("BMW")

Controller

public class HomeController : Controller
{
    VehicleInfoEntities db = new VehicleInfoEntities();

    public ActionResult Index()
    {
        var makes = db.prcGetMakes(null);

        return View(makes);
    }
}

We can close every window using Application.Exit(); Using this method we can close hidden windows also.

private void btnExitProgram_Click(object sender, EventArgs e) { Application.Exit(); }

For me, I was setting up a database with pgAdmin and it seems setting the owner during database creation was not enough. I had to navigate down to the 'public' schema and set the owner there as well (was originally 'postgres').

Since Spring 4.1 you could set up property values just in code by using org.springframework.test.context.TestPropertySource annotation on Unit Tests class level. You could use this approach even for injecting properties into dependent bean instances

For example

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = FooTest.Config.class)
@TestPropertySource(properties = {
    "some.bar.value=testValue",
})
public class FooTest {

  @Value("${some.bar.value}")
  String bar;

  @Test
  public void testValueSetup() {
    assertEquals("testValue", bar);
  }


  @Configuration
  static class Config {

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertiesResolver() {
        return new PropertySourcesPlaceholderConfigurer();
    }

  }

}

Note: It's necessary to have instance of org.springframework.context.support.PropertySourcesPlaceholderConfigurer in Spring context

Edit 24-08-2017: If you are using SpringBoot 1.4.0 and later you could initialize tests with @SpringBootTest and @SpringBootConfiguration annotations. More info here

In case of SpringBoot we have following code

@SpringBootTest
@SpringBootConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@TestPropertySource(properties = {
    "some.bar.value=testValue",
})
public class FooTest {

  @Value("${some.bar.value}")
  String bar;

  @Test
  public void testValueSetup() {
    assertEquals("testValue", bar);
  }

}

I've always used this syntax, which yields more predictable results than using !=.

<xsl:when test="not($AccountNumber = '12345') and not($Balance = '0')" />

Take a look at the open source WordPress application. They have a very re-usable window they have created for displaying an "activity in progress" type display over top of whatever view your application is currently displaying.

http://iphone.trac.wordpress.org/browser/trunk

The files you want are:

• WPActivityIndicator.xib
• RoundedRectBlack.png
• WPActivityIndicator.h
• WPActivityIndicator.m

Then to show it use something like:

[[WPActivityIndicator sharedActivityIndicator] show];

And hide with:

[[WPActivityIndicator sharedActivityIndicator] hide];

it works for me with a jar target:

<jar jarfile="${server.jar}" basedir="${classes.dir}" excludes="**/client/">
  <manifest>
    <attribute name="Main-Class" value="${mainServer.class}" />
  </manifest>
</jar>

this code include all files in "classes.dir" but exclude the directory "client" from the jar.

If it is one (single) branch that you need to check, for example if you want that branch 'B' is fully merged into branch 'A', you can simply do the following:

$ git checkout A
$ git branch -d B

git branch -d <branchname> has the safety that "The branch must be fully merged in HEAD."

Caution: this actually deletes the branch B if it is merged into A.

$ git rev-parse HEAD
273cf91b4057366a560b9ddcee8fe58d4c21e6cb

Update:

Alternatively (if you have tags):

(Good for naming a version, not very good for passing back to git.)

$ git describe
v0.1.49-localhost-ag-1-g273cf91

Or (as Mark suggested, listing here for completeness):

$ git show --oneline -s
c0235b7 Autorotate uploaded images based on EXIF orientation

Actually, the Sysinternals junction command only works with directories (don't ask me why), so it can't hardlink files. I would go with cmd /c mklink for soft links (I can't figure why it's not supported directly by PowerShell), or fsutil for hardlinks.

If you need it to work on Windows XP, I do not know of anything other than Sysinternals junction, so you might be limited to directories.

If you look at the examples on the api page there is this: Example: Creates a different alias instead of jQuery to use in the rest of the script.

var j = jQuery.noConflict();
// Do something with jQuery
j("div p").hide();
// Do something with another library's $()
$("content").style.display = 'none';

Put the var j = jQuery.noConflict() after you bring in jquery and then bring in the conflicting scripts. You can then use the j in place of $ for all your jquery needs and use the $ for the other script.

I think here is a simple and yet faster way, I tested it on the live server in comparison with a few above answer and it was faster.

 SELECT * FROM `table_name` WHERE id >= (SELECT FLOOR( MAX(id) * RAND()) FROM `table_name` ) ORDER BY id LIMIT 30; 

//Took 0.0014secs against a table of 130 rows

SELECT * FROM `table_name` WHERE 1 ORDER BY RAND() LIMIT 30

//Took 0.0042secs against a table of 130 rows

 SELECT name
FROM random AS r1 JOIN
   (SELECT CEIL(RAND() *
                 (SELECT MAX(id)
                    FROM random)) AS id)
    AS r2
WHERE r1.id >= r2.id
ORDER BY r1.id ASC
LIMIT 30

//Took 0.0040secs against a table of 130 rows

First change the array to a string by using implode() function. E.g $number=array(1,2,3,4,5,...); $stringofnumber=implode("|",$number); then pass the string to a session. e.g $_SESSION['string']=$stringofnumber; so when you go to the page where you want to use the array, just explode your string. e.g $number=explode("|", $_SESSION['string']); finally number is your array but remember to start array on the of each page.

It's better to avoid any kind of loops, just remove all elements directly like this:

$("#mytable > tbody").html("");

API = Dictionary of available words and their meanings (and the required grammar to combine them)

SDK = A Word processing system… for 2 year old babies… that writes right from ideas

Although you COULD go to school and become a master in your language after a few years, using the SDK will help you write whole meaningful sentences in no time (Forgiving the fact that, in this example, as a baby you haven't even gotten to learn any other language for at least to learn to use the SDK.)

As others have said, CGFloat is a float on 32-bit systems and a double on 64-bit systems. However, the decision to do that was inherited from OS X, where it was made based on the performance characteristics of early PowerPC CPUs. In other words, you should not think that float is for 32-bit CPUs and double is for 64-bit CPUs. (I believe, Apple's ARM processors were able to process doubles long before they went 64-bit.) The main performance hit of using doubles is that they use twice the memory and therefore might be slower if you are doing a lot of floating point operations.

You can do This : $("#td_id").removeClass('Old_class'); $("#td_id").addClass('New_class'); Or You can do This

$("#td_id").removeClass('Old_class').addClass('New_class');

\begin{tikzpicture}

    \tikzstyle{every node}=[font=\small]

\end{tikzpicture}

will give you font size control on every node.

For me this query work fine in Mysql it will return third max salary from table

SELECT salary FROM users ORDER BY salary DESC LIMIT 1 OFFSET 2;

or

SELECT salary FROM users ORDER BY salary DESC LIMIT 2,1;

const img = '../../img/splash/splash_bg.png';
<ImageBackground  source={{ uri: img }} style={styles.backgroundImage} >
    </ImageBackground>

This worked for me. Reference to RN docs can be found here.I wrote mine by reading this- https://facebook.github.io/react-native/docs/images.html#background-image-via-nesting

You are missing that rsync can also compare files by checksum.

--size-only means that rsync will skip files that match in size, even if the timestamps differ. This means it will synchronise fewer files than the default behaviour. It will miss any file with changes that don't affect the overall file size. If you have something that changes the dates on files without changing the files, and you don't want rsync to spend lots of time checksumming those files to discover they haven't changed, this is the option to use.

--ignore-times means that rsync will checksum every file, even if the timestamps and file sizes match. This means it will synchronise more files than the default behaviour. It will include changes to files even where the file size is the same and the modification date/time has been reset to the original value. Checksumming every file means it has to be entirely read from disk, which may be slow. Some build pipelines will reset timestamps to a specific date (like 1970-01-01) to ensure that the final build file is reproducible bit for bit, e.g. when packed into a tar file that saves the timestamps.

Both the verifyNoMoreInteractions() and verifyZeroInteractions() method internally have the same implementation as:

public static transient void verifyNoMoreInteractions(Object mocks[])
{
    MOCKITO_CORE.verifyNoMoreInteractions(mocks);
}

public static transient void verifyZeroInteractions(Object mocks[])
{
    MOCKITO_CORE.verifyNoMoreInteractions(mocks);
}

so we can use any one of them on mock object or array of mock objects to check that no methods have been called using mock objects.

This is one way to do it:

string = "this is a string"
ssplit = string.split()
for word in ssplit:
    print (word)

Output:

this
is
a
string

Here is the code that worked for me!

Assuming that you have a valid session going,

//Get the current users id
$uid = $facebook->getUser();

//create the url
$profile_pic =  "http://graph.facebook.com/".$uid."/picture";

//echo the image out
echo "<img src=\"" . $profile_pic . "\" />";

Thanx goes to Raine, you da man!

I had this issue with a WinForms Project using VS 2015. My solution was:

1. right click the Project
2. select properties
3. check "Prefer 32-bit"
4. Platform target: Any CPU

You could try..

comm -13 <(sort file1) <(sort file2) > file3

or

grep -Fxvf file1 file2 > file3

or

diff file1 file2 | grep "<" | sed 's/^<//g'  > file3

or

join -v 2 <(sort file1) <(sort file2) > file3

I did use following solution to this:

findAllByStartDateLessThanEqualAndEndDateGreaterThanEqual(OffsetDateTime endDate, OffsetDateTime startDate);

It's just what it says:

inputFile = open((x), encoding = "utf8", "r")

You have specified encoding as a keyword argument, but "r" as a positional argument. You can't have positional arguments after keyword arguments. Perhaps you wanted to do:

inputFile = open((x), "r", encoding = "utf8")

There is a third recovery mode not mentioned above. The recovery mode ultimately determines how large the LDF files become and how ofter they are written to. In cases where you are going to be doing any type of bulk inserts, you should set the DB to be in "BULK/LOGGED". This makes bulk inserts move speedily along and can be changed on the fly.

To do so,

USE master ;
ALTER DATABASE model SET RECOVERY BULK_LOGGED ;

To change it back:

USE master ;
ALTER DATABASE model SET RECOVERY FULL ;

In the spirit of adding to the conversation about why someone would not want an LDF, I add this: We do multi-dimensional modelling. Essentially we use the DB as a large store of variables that are processed in bulk using external programs. We do not EVER require rollbacks. If we could get a performance boost by turning of ALL logging, we'd take it in a heart beat.

Set followings on your my.cnf file and restart mysql server.

I wrote a helper for my razor project using some of the hints from other answers.

The ParseQueryString business is necessary because we are not allowed to tamper with the QueryString object of the current request.

@helper GetQueryStringWithValue(string key, string value) {
    var queryString = System.Web.HttpUtility.ParseQueryString(HttpContext.Current.Request.QueryString.ToString());
    queryString[key] = value;
    @Html.Raw(queryString.ToString())
}

I use it like this:

location.search = '[email protected]("var-name", "var-value")';

If you want it to take more than one value, just change the parameters to a Dictionary and add the pairs to the query string.

In the UK, there are a few government standards which deal successfully with the bulk of the UK population -- the Passport Office, the Driver & Vehicle Licensing Agency, the Deed Poll office, and the NHS. They use different standards, obviously.

Changing your name by Deed Poll allows 300 characters;

There is no legal limit on the length of your name, but we impose a limit of 300 characters (including spaces) for your full name.

The NHS uses 70 characters for patient names

PATIENT NAME
Format/length: max an70

The Passport Office allows 30+30 first/last and Driving Licenses (DVLA) is 30 total.

Note that other organisations will have their own restrictions about what they will show on the documents they produce — for HM Passport Office the limit is 30 characters each for your forename and your surname, and for the DVLA the limit is 30 characters in total for your full name.

create a package protected (assumes test class in same package) method in the sub class that calls the super class method and then call that method in your overridden sub class method. you can then set expectations on this method in your test through the use of the spy pattern. not pretty but certainly better than having to deal with all the expectation setting for the super method in your test

These three commands have entirely different purposes. They are not even remotely similar.

git revert

This command creates a new commit that undoes the changes from a previous commit. This command adds new history to the project (it doesn't modify existing history).

git checkout

This command checks-out content from the repository and puts it in your work tree. It can also have other effects, depending on how the command was invoked. For instance, it can also change which branch you are currently working on. This command doesn't make any changes to the history.

git reset

This command is a little more complicated. It actually does a couple of different things depending on how it is invoked. It modifies the index (the so-called "staging area"). Or it changes which commit a branch head is currently pointing at. This command may alter existing history (by changing the commit that a branch references).

Using these commands

If a commit has been made somewhere in the project's history, and you later decide that the commit is wrong and should not have been done, then git revert is the tool for the job. It will undo the changes introduced by the bad commit, recording the "undo" in the history.

If you have modified a file in your working tree, but haven't committed the change, then you can use git checkout to checkout a fresh-from-repository copy of the file.

If you have made a commit, but haven't shared it with anyone else and you decide you don't want it, then you can use git reset to rewrite the history so that it looks as though you never made that commit.

These are just some of the possible usage scenarios. There are other commands that can be useful in some situations, and the above three commands have other uses as well.

This will depend on the logging configuration. The default value will depend on the framework being used. The idea is that later on by changing a configuration setting from INFO to DEBUG you will see a ton of more (or less if the other way around) lines printed without recompiling the whole application.

If you think which one to use then it boils down to thinking what you want to see on which level. For other levels for example in Log4J look at the API, http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Level.html

It appears that this is a FAQ, and the resolution offered is:

Simple search (Ctrl+H) without regexp

You can turn on View/Show End of Line or view/Show All, and select the now visible newline characters. Then when you start the command some characters matching the newline character will be pasted into the search field. Matches will be replaced by the replace string, unlike in regex mode.

Note 1: If you select them with the mouse, start just before them and drag to the start of the next line. Dragging to the end of the line won't work.

Note 2: You can't copy and paste them into the field yourself.

Advanced search (Ctrl+R) without regexp

Ctrl+M will insert something that matches newlines. They will be replaced by the replace string.

Your solution is correct, but your outer loop is still longer than needed. You don't need to compare the last element with anything else because it's been already compared with all the others in the previous iterations. Your inner loop still prevents that, but since we're talking about collision detection you can save the unnecessary check.

Using the same language you used to illustrate your algorithm, you'd come with something like this:

for (int i = 0, i < mylist.size() - 1; ++i)
    for (int j = i + 1, j < mylist.size(); --j)
        compare(mylist[i], mylist[j])

This post is intended to rescue the people who are suffering from *not being able to properly setup Apache2 for Perl on Ubuntu. (The system configurations specific to your Linux machine will be mentioned within square brackets, like [this]).

Possible outcome of an improperly setup Apache 2:

1. Browser trying to download the .pl file instead of executing and giving out the result.
2. Forbidden.
3. Internal server error.

If one follows the steps described below with a reasonable intelligence, he/she can get through the errors mentioned above.

<Files ~ "\.(pl|cgi)$">
SetHandler perl-script
PerlResponseHandler ModPerl::PerlRun

Step 7:

Now add, your Perl script as test.pl in the place where you mentioned before in step 3 as [path-where-you-want-your-.pl-and-.cgi-files].

Give permissions to the .pl file using chmod and then, type the webaddress/cgi-bin/test.pl in the address bar of the browser, there you go, you got it.

It is not possible with the default Link List web part, but there are resources describing how to extend Sharepoint server-side to add this functionality.

Share Point Links Open in New Window
Changing Link Lists in Sharepoint 2007

In python, you can put ‘j’ or ‘J’ after a number to make it imaginary, so you can write complex literals easily:

>>> 1j
1j
>>> 1J
1j
>>> 1j * 1j
(-1+0j)

The ‘j’ suffix comes from electrical engineering, where the variable ‘i’ is usually used for current. (Reasoning found here.)

The type of a complex number is complex, and you can use the type as a constructor if you prefer:

>>> complex(2,3)
(2+3j)

A complex number has some built-in accessors:

>>> z = 2+3j
>>> z.real
2.0
>>> z.imag
3.0
>>> z.conjugate()
(2-3j)

Several built-in functions support complex numbers:

>>> abs(3 + 4j)
5.0
>>> pow(3 + 4j, 2)
(-7+24j)

The standard module cmath has more functions that handle complex numbers:

>>> import cmath
>>> cmath.sin(2 + 3j)
(9.15449914691143-4.168906959966565j)

The best way to get a browser's default styling on something is to not style the element at all in the first place.

$(document).ready(function() {
 $('#chkdwn2').click(function() {
   if ($('#chkdwn2').prop('checked')) {
      $('#dropdown').prop('disabled', true);
   } else {
      $('#dropdown').prop('disabled', false);  
   }
 });
});

making use of .prop in the if statement.

RABL is probably the nicest solution to this that I've seen if you're looking for a cleaner alternative to ERb syntax. json_builder and argonaut, which are other solutions, both seem somewhat outdated and won't work with Rails 3.1 without some patching.

RABL is available via a gem or check out the GitHub repository; good examples too

https://github.com/nesquena/rabl

Join commands with "&&".

os.system('echo a > outputa.txt && echo b > outputb.txt')

The answer is not simple:

It depends on the target machines (mobile vs desktop), it depends on the nature of your data, the browser, the OS, the hardware it runs on... you will need to benchmark if you really want to know.

It is mostly a memory vs computation problem ... as with most performance issues the difference can become significant with repeated elements (n) like lists, especially when nested (n x n, or worse) and also what kind of computations you run inside these elements:

• ng-show: If those optional elements are often present (dense), like say 90% of the time, it may be faster to have them ready and only show/hide them, especially if their content is cheap (just plain text, nothing to compute or load). This consumes memory as it fills the DOM with hidden elements, but just show/hide something which already exists is likely to be a cheap operation for the browser.

• ng-if: If on the contrary elements are likely not to be shown (sparse) just build them and destroy them in real time, especially if their content is expensive to get (computations/sorted/filtered, images, generated images). This is ideal for rare or 'on-demand' elements, it saves memory in terms of not filling the DOM but can cost a lot of computation (creating/destroying elements) and bandwidth (getting remote content). It also depends on how much you compute in the view (filtering/sorting) vs what you already have in the model (pre-sorted/pre-filtered data).

You can use Github Contents API to get an archive link and tar to retrieve a specified folder.

Command line:

curl https://codeload.github.com/[owner]/[repo]/tar.gz/master | \ tar -xz --strip=2 [repo]-master/[folder_path]

For example,
if you want to download examples/with-apollo/ folder from zeit/next.js, you can type this:

curl https://codeload.github.com/zeit/next.js/tar.gz/master | \
  tar -xz --strip=2 next.js-master/examples/with-apollo

Set the image's width to 100%, and the image's height will adjust itself:

<img style="width:100%;" id="image" src="...">

If you have a custom CSS, then:

HTML:

<img id="image" src="...">

CSS:

#image
{
    width: 100%;
}

Also, you could do File -> View Source next time, or maybe Google.

Font awesome use SVG icons. So, you can resize it for your requirment.

just use CSS class for that,

    .large-icon{
       font-size:10em;
       //or
      font-size:200%;
      //or
      font-size:50px;
    }

: has special meaning: it is The time separator. (Custom Date and Time Format Strings).

Use \ to escape it:

DateTime.ToString(@"MM/dd/yyyy HH\:mm\:ss.fff")

Or use CultureInfo.InvariantCulture:

DateTime.ToString("MM/dd/yyyy HH:mm:ss.fff", CultureInfo.InvariantCulture)

I would suggest going with the second one, because / has special meaning as well (it is The date separator.), so you can have problems with that too.

The standard way to import AAR file in an application is given in https://developer.android.com/studio/projects/android-library.html#AddDependency

Click File > New > New Module. Click Import .JAR/.AAR Package then click Next. Enter the location of the compiled AAR or JAR file then click Finish.

Please refer the link above for next steps.

<%= Html.Partial("PartialName", Model) %>

The proposed solutions did not help me with ".child {width: 100%;}", since I had more complicated markup. However, I found a solution - remove "align-items: center;", and it works for this case too.

.parent {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  width: 400px;_x000D_
  border: 1px solid red;_x000D_
  /*align-items: center;*/_x000D_
}_x000D_
.child {_x000D_
  border: 1px solid blue;_x000D_
}

<div class="parent">_x000D_
  <div class="child">_x000D_
    Lorem Ipsum is simply dummy text of the printing and typesetting industry_x000D_
  </div>_x000D_
  <div class="child">_x000D_
    Lorem Ipsum is simply dummy text of the printing and typesetting industry_x000D_
  </div>_x000D_
</div>

this issue occur for me after downgrade Java JDK, after upgrade JDK my problem resolved.

You should also try checking the error messages in curl_error(). You might need to do this once after each curl_* function.

http://www.php.net/curl_error

The use of http.createClient is now deprecated. You can pass Headers in options collection as below.

var options = { 
    hostname: 'example.com',
    path: '/somePath.php',
    method: 'GET',
    headers: {'Cookie': 'myCookie=myvalue'}
};
var results = ''; 
var req = http.request(options, function(res) {
    res.on('data', function (chunk) {
        results = results + chunk;
        //TODO
    }); 
    res.on('end', function () {
        //TODO
    }); 
});

req.on('error', function(e) {
        //TODO
});

req.end();

The pointer-events could be useful for this problem as you would be able to put a div over the arrow button, but still be able to click the arrow button.

The pointer-events css makes it possible to click through a div.

This approach will not work for IE versions older than IE11, however. You could something working in IE8 and IE9 if the element you put on top of the arrow button is an SVG element, but it will be more complicated to style the button the way you want proceeding like this.

Here a Js fiddle example: http://jsfiddle.net/e7qnqzx6/2/

I created .pfx file from .key and .pem files.

Like this openssl pkcs12 -inkey rootCA.key -in rootCA.pem -export -out rootCA.pfx

That's not the direct answer but still maybe it helps out someone else.

What about trying with VLOOKUP? The syntax is:

=VLOOKUP(cell you want to copy, range you want to copy, 1, FALSE).

It should do the trick.

Probably invalid syntax in your onChange event, I avoid using like this (within the html) as I think it is messy and it is hard enough keeping JavaScript tidy at the best of times.

I would rather register the event on the document ready event in javascript. You will also definitely want to use keyup event too if you want the validation as the user is typing:

$(document).ready(function () {
   $("#txtConfirmPassword").keyup(checkPasswordMatch);
});

Here is a working example

Personally I would prefer to do the check when either password field changes, that way if they re-type the original password then you still get the same validation check:

$(document).ready(function () {
   $("#txtNewPassword, #txtConfirmPassword").keyup(checkPasswordMatch);
});

Here is a working example

If you want to fully automate the process (i.e. you want to increment the version number without having to know what the current version number is), you can do this:

mvn build-helper:parse-version versions:set -DnewVersion=\${parsedVersion.majorVersion}.\${parsedVersion.minorVersion}.\${parsedVersion.nextIncrementalVersion} versions:commit

Pythonic + Pandorable: df[df['col'].astype(bool)]

Empty strings are falsy, which means you can filter on bool values like this:

df = pd.DataFrame({
    'A': range(5),
    'B': ['foo', '', 'bar', '', 'xyz']
})
df
   A    B
0  0  foo
1  1     
2  2  bar
3  3     
4  4  xyz

df['B'].astype(bool)                                                                                                                      
0     True
1    False
2     True
3    False
4     True
Name: B, dtype: bool

df[df['B'].astype(bool)]                                                                                                                  
   A    B
0  0  foo
2  2  bar
4  4  xyz

If your goal is to remove not only empty strings, but also strings only containing whitespace, use str.strip beforehand:

df[df['B'].str.strip().astype(bool)]
   A    B
0  0  foo
2  2  bar
4  4  xyz

Faster than you Think

.astype is a vectorised operation, this is faster than every option presented thus far. At least, from my tests. YMMV.

Here is a timing comparison, I've thrown in some other methods I could think of.

Benchmarking code, for reference:

import pandas as pd
import perfplot

df1 = pd.DataFrame({
    'A': range(5),
    'B': ['foo', '', 'bar', '', 'xyz']
})

perfplot.show(
    setup=lambda n: pd.concat([df1] * n, ignore_index=True),
    kernels=[
        lambda df: df[df['B'].astype(bool)],
        lambda df: df[df['B'] != ''],
        lambda df: df[df['B'].replace('', np.nan).notna()],  # optimized 1-col
        lambda df: df.replace({'B': {'': np.nan}}).dropna(subset=['B']),  
    ],
    labels=['astype', "!= ''", "replace + notna", "replace + dropna", ],
    n_range=[2**k for k in range(1, 15)],
    xlabel='N',
    logx=True,
    logy=True,
    equality_check=pd.DataFrame.equals)

For me this happened because i merged a branch dev into master using web interface and then tried to sync/pull using VSCode which was open on dev branch.(its weird that i could not change to master without getting this error.)

git pull
Your configuration specifies to merge with the ref 'refs/heads/dev'
from the remote, but no such ref was fetched.'

It makes sense that is not finding it refs/heads/dev - for me it was easier to just delete the local folder and clone again.

Taking as a given you have a "large" number of data.frames with similar names (here d# where # is some positive integer), the following is a slight improvement of @mark-miller's method. It is more terse and returns a named list of data.frames, where each name in the list is the name of the corresponding original data.frame.

The key is using mget together with ls. If the data frames d1 and d2 provided in the question were the only objects with names d# in the environment, then

my.list <- mget(ls(pattern="^d[0-9]+"))

which would return

my.list
$d1
  y1 y2
1  1  4
2  2  5
3  3  6

$d2
  y1 y2
1  3  6
2  2  5
3  1  4

This method takes advantage of the pattern argument in ls, which allows us to use regular expressions to do a finer parsing of the names of objects in the environment. An alternative to the regex "^d[0-9]+$" is "^d\\d+$".

As @gregor points out, it is a better overall to set up your data construction process so that the data.frames are put into named lists at the start.

data

d1 <- data.frame(y1 = c(1,2,3),y2 = c(4,5,6))
d2 <- data.frame(y1 = c(3,2,1),y2 = c(6,5,4))

I followed the solution by poke with a minor adjustment in the end. My steps follow
- git fetch --prune;
- git branch -a printing the following
    master
    branch
    remotes/origin/HEAD -> origin/master
    remotes/origin/master
    remotes/origin/branch (remote branch to remove)
- git push origin --delete branch.
Here, the branch to remove is not named as remotes/origin/branch but simply branch. And the branch is removed.

If you are doing local testing or calling the file from something like file:// then you need to disable browser security.

On MAC: open -a Google\ Chrome --args --disable-web-security

Use the For-Each loop which came with Java 1.5, and it work on Types which are iterable.

ArrayList<String> data = new ArrayList<String>();
data.add("Vivek");
data.add("Vadodara");
data.add("Engineer");
data.add("Feelance");

for (String s : data){

 System.out.prinln("Data of "+data.indexOf(s)+" "+s);

 }

The only way that worked for me is creating a Boolean variable that I set to true when I add the event. Then I ask: If the variable is false, I add the event.

bool alreadyAdded = false;

This variable can be global.

if(!alreadyAdded)
{
    myClass.MyEvent += MyHandler;
    alreadyAdded = true;
}

If you have the char array null terminated, you can assign the char array to the string:

char[] chArray = "some characters";
String String(chArray);

As for your loop code, it looks right, but I will try on my controller to see if I get the same problem.

Another way if you want to delete the file from your local folder using rm command and then push the changes to the remote server.

rm file1.txt

git commit -a -m "Deleting files"

git push origin master

[DisplayName("Start Date")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:yyyy-MM-dd}")]
public DateTime StartDate { get; set; }

Then:

<%=Html.EditorFor(m => m.StartDate) %>

JSON.parse() function will do.

or

Using Jquery,

var obj = jQuery.parseJSON( '{ "name": "Vinod" }' );
alert( obj.name === "Vinod" );

I've updated Eric D's answer for Swift 5:

 func convertStringToDictionary(text: String) -> [String:AnyObject]? {
    if let data = text.data(using: .utf8) {
        do {
            let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String:AnyObject]
            return json
        } catch {
            print("Something went wrong")
        }
    }
    return nil
}

The version suggested by kennebec will fail when changing to or from DST, since it is the hour number that is set.

this.setUTCHours(this.getUTCHours()+h);

will add h hours to this independent of time system peculiarities. Jason Harwig's method works as well.

The simplest approach would be to use any of these class utilities that Bootstrap provides:

<div class="position-fixed">...</div>
<div class="position-sticky">...</div>
<div class="fixed-top">...</div>
<div class="fixed-bottom">...</div>
<div class="sticky-top">...</div>

Although you cannot use different sized slides in one PowerPoint file, for the actual presentation you can link several different files together to create a presentation that has different slide sizes.

The process to do so is as follows:

1. Create the two Powerpoints (with your desired slide dimensions)
   • They need to be properly filled in to have linkable objects and selectable slides
2. Select an object in the main PowerPoint to act as the hyperlink
3. Go to "Insert -> Links -> Action"
4. Select either the "Mouse Click" or the "Mouse Over" tab
5. Select "Hyperlink to:" and in the drop down menu choose "other PowerPoint Presentation"
6. Select the slide that you want to link to.
   • Any slide that isn't empty should appear in the "Hyperlink to Slide" dialog box
7. Repeat the Process in the second Presentation to link back to your main presentation

Okay so little bit of digging and I found these gems from Bill Philips article on RecycleView

RecyclerView can do more than ListView, but the RecyclerView class itself has fewer responsibilities than ListView. Out of the box, RecyclerView does not:

• Position items on the screen
• Animate views
• Handle any touch events apart from scrolling

All of this stuff was baked in to ListView, but RecyclerView uses collaborator classes to do these jobs instead.

The ViewHolders you create are beefier, too. They subclass RecyclerView.ViewHolder, which has a bunch of methods RecyclerView uses. ViewHolders know which position they are currently bound to, as well as which item ids (if you have those). In the process, ViewHolder has been knighted. It used to be ListView’s job to hold on to the whole item view, and ViewHolder only held on to little pieces of it.

Now, ViewHolder holds on to all of it in the ViewHolder.itemView field, which is assigned in ViewHolder’s constructor for you.

A other users suggested,

.empty()

is good enought, because it removes all descendant nodes (both tag-nodes and text-nodes) AND all kind of data stored inside those nodes. See the JQuery's API empty documentation.

If you wish to keep data, like event handlers for example, you should use

.detach()

as described on the JQuery's API detach documentation.

The method .remove() could be usefull for similar purposes.

using str.replace(regex, $1);:

var str   = 'asd-0.testing';
var regex = /(asd-)\d(\.\w+)/;

if (str.match(regex)) {
    str = str.replace(regex, "$1" + "1" + "$2");
}

Edit: adaptation regarding the comment

As others have noted the call to .remove() is asynchronous. We should all be aware nothing happens 'instantly', even if it is at the speed of light.

What you mean by 'instantly' is that the next line of code should be able to execute after the call to .remove(). With asynchronous operations the next line may be when the data has been removed, it may not - it is totally down to chance and the amount of time that has elapsed.

.remove() takes one parameter a callback function to help deal with this situation to perform operations after we know that the operation has been completed (with or without an error). .push() takes two params, a value and a callback just like .remove().

Here is your example code with modifications:

ref = new Firebase("myfirebase.com")

ref.push({key:val}, function(error){
  //do stuff after push completed
});

// deletes all data pushed so far
ref.remove(function(error){
  //do stuff after removal
});

You need to ensure that any code that modifies the HTTP headers is executed before the headers are sent. This includes statements like session_start(). The headers will be sent automatically when any HTML is output.

Your problem here is that you're sending the HTML ouput at the top of your page before you've executed any PHP at all.

Move the session_start() to the top of your document :

<?php    session_start(); ?> <html> <head> <title>PHP SDK</title> </head> <body> <?php require_once 'src/facebook.php';    // more PHP code here. 

Swift 3.0/4.0

If you have created your own custom cell you can change the selection color on awakeFromNib() for all of the cells:

 override func awakeFromNib() {
    super.awakeFromNib()

    let colorView = UIView()
    colorView.backgroundColor = UIColor.orange.withAlphaComponent(0.4)

    self.selectedBackgroundView = colorView


}

When you use count = count + 3 or count = count + 9 instead of count = count + 1, the value of count will never be 100, and hence it enters an infinite loop.

You could use the following code for your condition to work

while count < 100:

Now the loop will terminate when count >= 100.

You can write this in a more compact way:

var now = new Date();
now.setTime(now.getTime() + 1 * 3600 * 1000);
document.cookie = "name=value; expires=" + now.toUTCString() + "; path=/";

And for someone like me, who wasted an hour trying to figure out why the cookie with expiration is not set up (but without expiration can be set up) in Chrome, here is in answer:

For some strange reason Chrome team decided to ignore cookies from local pages. So if you do this on localhost, you will not be able to see your cookie in Chrome. So either upload it on the server or use another browser.

For me it worked a simple sudo pip -I install <package>.

As man pip states, -I ignores installed packages, forcing reinstall instead.

The difference is that raw_input() does not exist in Python 3.x, while input() does. Actually, the old raw_input() has been renamed to input(), and the old input() is gone, but can easily be simulated by using eval(input()). (Remember that eval() is evil. Try to use safer ways of parsing your input if possible.)

In large this question has been answered but in small parts by everyone. I dealt with this just a minute ago.

I wanted to have a button tray at the bottom of a panel where the panel has 30px all around. The button tray had to be flush bottom and sides.

.panel
{
  padding: 30px;
}

.panel > .actions
{
  margin: -30px;
  margin-top: 30px;
  padding: 30px;
  width: auto;
}

I did a demo here with more flesh to drive the idea. However the key elements above are offset any parent padding with matching negative margins on the child. Then most critical if you want to run the child full-width then set width to auto. (as mentioned in a comment above by schlingel).

The following ex commands will (re-)split any number of windows:

• To split vertically (e.g. make vertical dividers between windows), type :vertical ball
• To split horizontally, type :ball

If there are hidden buffers, issuing these commands will also make the hidden buffers visible.

1. Go to SVN repo directory into the subfolder "hooks", e.g. "D:\SVN\hooks\"
2. create the empty file "pre-revprop-change.bat" there
3. in the file write "exit 0" (without "") and save it
4. enjoy :)

(This solution surely has drawbacks, as nothing is checked/prohibited. But for my case - a local repo that only I am using - it seems to work.)

Installed it using pip on Ubuntu 15.10 using a normal user, it was put in ~/.local/bin/virtualenvwrapper.sh which I found by running:

$ find / -name virtualenvwrapper.sh 2>/dev/null

If the NFS server disappeared and you can't get it back online, one trick that I use is to add an alias to the interface with the IP of the NFS server (in this example, 192.0.2.55).

Linux

The command for that is something roughly like:

ifconfig eth0:fakenfs 192.0.2.55 netmask 255.255.255.255

Where 192.0.2.55 is the IP of the NFS server that went away. You should then be able to ping the address, and you should also be able to unmount the filesystem (use unmount -f). You should then destroy the aliased interface so you no longer route traffic to the old NFS server to yourself with:

ifconfig eth0:fakenfs down

FreeBSD and similar operating systems

The command would be something like:

ifconfig em0 alias 192.0.2.55 netmask 255.255.255.255

And then to remove it:

ifconfig em0 delete 192.0.2.55

man ifconfig(8) for more!

you should use the below update query

UPDATE dbo.xxx SET Value=REPLACE(Value,'123\','') WHERE Id IN(1, 2, 3, 4)

UPDATE dbo.xxx SET Value=REPLACE(Value,'123\','') WHERE Id <= 4

Either of the above queries should work.

POJO stands for Plain Old Java Object, and would be used to describe the same things as a "Normal Class" whereas a JavaBean follows a set of rules. Most commonly Beans use getters and setters to protect their member variables, which are typically set to private and have a no-argument public constructor. Wikipedia has a pretty good rundown of JavaBeans: http://en.wikipedia.org/wiki/JavaBeans

POJO is usually used to describe a class that doesn't need to be a subclass of anything, or implement specific interfaces, or follow a specific pattern.

Well you can convert one byte (unsigned char) at a time into a array like so

char buffer [17];
buffer[16] = 0;
for(j = 0; j < 8; j++)
    sprintf(&buffer[2*j], "%02X", data[j]);

Using display:inline-block

#element1 {display:inline-block;margin-right:10px;} 
#element2 {display:inline-block;} 

Example

You can run advanced queries via AWS Config (and from the CLI for Config), that will list all resources. If you define an aggregator that covers all reasons (and perhaps multiple accounts), you can get a very comprehensive view . . . As simple as "SELECT *"

Something like this:

var div = document.getElementById("result");_x000D_
_x000D_
var str = "{'a':1}";_x000D_
  str = str.replace(/\'/g, '"');_x000D_
  var parsed = JSON.parse(str);_x000D_
  console.log(parsed);_x000D_
  div.innerText = parsed.a;

<div id="result"></div>

For Windows line endings:

(Turn on regex - Alt+R)

Find: \\r\\n

Replace: \r\n

Using ruby:

ruby -ne 'puts "#{$.}: #{$_}" if $. >= 32613500 && $. <= 32614500' < GND.rdf > GND.extract.rdf

Let's answer your questions one by one.

1. Yes, you make a new object whenever this statement is executed, however, it goes "out of scope" when you exit the method and it is eligible for garbage collection.
2. Well this would be the same as #1, except that you've used a string type. A string type is immutable and you get a new object every time you make an assignment.
3. Yes the garbage collector collects the out of scope objects, unless you assign the object to a variable with a large scope such as class variable.
4. Yes.
5. The using statement only applies to objects that implement the IDisposable interface. If that is the case, by all means using is best for objects within a method's scope. Don't put Foo o at a larger scope unless you have a good reason to do so. It is best to limit the scope of any variable to the smallest scope that makes sense.

For rerender you can use in parent component

<template>
  <div v-if="renderComponent">content</div>
</template>
<script>
export default {
   data() {
      return {
        renderComponent: true,
      };
    },
    methods: {
      forceRerender() {
        // Remove my-component from the DOM
        this.renderComponent = false;

        this.$nextTick(() => {
          // Add the component back in
          this.renderComponent = true;
        });
      }
    }
}
</script>
