For me this popped up when I accidentally called "super.init()" inside a completionHandler of a method that was called from the class init method.

init() {        
        someFunction(argument, completionHandler: { (data) -> () in
            super.init()
...
}

instead of

init() {    
        super.init()
        someFunction(argument, completionHandler: { (data) -> () in
        ...
}

Take a look at this MSDN reference. In the notes it states that the numbers are rounded to the number of decimal places requested.

If instead you use "{0:R}" it will produce what's referred to as a "round-trip" value, take a look at this MSDN reference for more info, here's my code and the output:

double d = 10 * 0.69;
Console.WriteLine("  {0:R}", d);
Console.WriteLine("+ {0:F20}", 6.9 - d);
Console.WriteLine("= {0:F20}", 6.9);

output

  6.8999999999999995
+ 0.00000000000000088818
= 6.90000000000000000000

Works great for me, and you can chose how much you want to go back in the functions:

function getCaller(functionBack= 0) {
    const back = functionBack * 2;
    const stack = new Error().stack.split('at ');
    const stackIndex = stack[3 + back].includes('C:') ? (3 + back) : (4 + back);
    const isAsync = stack[stackIndex].includes('async');
    let result;
    if (isAsync)
      result = stack[stackIndex].split(' ')[1].split(' ')[0];
    else
      result = stack[stackIndex].split(' ')[0];
    return result;
}

Upgrade your SqlServer management studio from 2008 to 2012

Or Download the service packs of SqlServer Management Studio and update probably resolve you solution

I was designing a html email and had a similar problem. But having every cell with the fixed width is not what I want. I'd like to have the equal spacing between the contents of the columns, like the following

|---something---|---a very long thing---|---short---|

After a lot of trial and error, I came up with the following

<style>
    .content {padding: 0 20px;}
</style>

table width="400"
    tr
        td
            a.content something
        td 
            a.content a very long thing
        td 
            a.content short

Issues of concern:

1. Outlook 2007/2010/2013 don't support padding. Having the width of the table set will allow the widths of the columns to automatically set. This way, though the contents will not have equal spacing. They at least have some spacing between them.

2. Automatic width setting for table columns will not give equal spacing between the contents The padding added for the contents will force the equal spacing.

Just as maasg says you can create a new DataFrame from the result of a map applied to the old DataFrame. An example for a given DataFrame df with two rows:

val newDf = sqlContext.createDataFrame(df.map(row => 
  Row(row.getInt(0) + SOMETHING, applySomeDef(row.getAs[Double]("y")), df.schema)

Note that if the types of the columns change, you need to give it a correct schema instead of df.schema. Check out the api of org.apache.spark.sql.Row for available methods: https://spark.apache.org/docs/latest/api/java/org/apache/spark/sql/Row.html

[Update] Or using UDFs in Scala:

import org.apache.spark.sql.functions._

val toLong = udf[Long, String] (_.toLong)

val modifiedDf = df.withColumn("modifiedColumnName", toLong(df("columnName"))).drop("columnName")

and if the column name needs to stay the same you can rename it back:

modifiedDf.withColumnRenamed("modifiedColumnName", "columnName")

Track the remote branch

You can specify the default remote repository for pushing and pulling using git-branch’s track option. You’d normally do this by specifying the --track option when creating your local master branch, but as it already exists we’ll just update the config manually like so:

Edit your .git/config

[branch "master"]
  remote = origin
  merge = refs/heads/master

Now you can simply git push and git pull.

You can find all of those operators in the Python language reference, though you'll have to scroll around a bit to find them all. As other answers have said:

• The ** operator does exponentiation. a ** b is a raised to the b power. The same ** symbol is also used in function argument and calling notations, with a different meaning (passing and receiving arbitrary keyword arguments).
• The ^ operator does a binary xor. a ^ b will return a value with only the bits set in a or in b but not both. This one is simple!
• The % operator is mostly to find the modulus of two integers. a % b returns the remainder after dividing a by b. Unlike the modulus operators in some other programming languages (such as C), in Python a modulus it will have the same sign as b, rather than the same sign as a. The same operator is also used for the "old" style of string formatting, so a % b can return a string if a is a format string and b is a value (or tuple of values) which can be inserted into a.
• The // operator does Python's version of integer division. Python's integer division is not exactly the same as the integer division offered by some other languages (like C), since it rounds towards negative infinity, rather than towards zero. Together with the modulus operator, you can say that a == (a // b)*b + (a % b). In Python 2, floor division is the default behavior when you divide two integers (using the normal division operator /). Since this can be unexpected (especially when you're not picky about what types of numbers you get as arguments to a function), Python 3 has changed to make "true" (floating point) division the norm for division that would be rounded off otherwise, and it will do "floor" division only when explicitly requested. (You can also get the new behavior in Python 2 by putting from __future__ import division at the top of your files. I strongly recommend it!)

This worked for me.

header = ['row1', 'row2', 'row3']
some_list = [1, 2, 3]
with open('test.csv', 'wt', newline ='') as file:
    writer = csv.writer(file, delimiter=',')
    writer.writerow(i for i in header)
    for j in some_list:
        writer.writerow(j)

You might also consider removing the need for duplicated parameter names in your Sql by changing your Sql to

table.Variable2 LIKE '%' || :VarB || '%'

and then getting your client to provide '%' for any value of VarB instead of null. In some ways I think this is more natural.

You could also change the Sql to

table.Variable2 LIKE '%' || IfNull(:VarB, '%') || '%'

The Get-ChildItem cmdlet has an -Exclude parameter that is tempting to use but it doesn't work for filtering out entire directories from what I can tell. Try something like this:

function GetFiles($path = $pwd, [string[]]$exclude) 
{ 
    foreach ($item in Get-ChildItem $path)
    {
        if ($exclude | Where {$item -like $_}) { continue }

        if (Test-Path $item.FullName -PathType Container) 
        {
            $item 
            GetFiles $item.FullName $exclude
        } 
        else 
        { 
            $item 
        }
    } 
}

This looks like a Bootstrap issue...

Currently, here's a workaround : add .col-xs-12 to your responsive image.

Do you want to find elements that contain "match", or that equal "match"?

This will find elements that have text nodes that equal 'match' (matches none of the elements because of leading and trailing whitespace in random2):

//*[text()='match']

This will find all elements that have text nodes that equal "match", after removing leading and trailing whitespace(matches random2):

//*[normalize-space(text())='match']

This will find all elements that contain 'match' in the text node value (matches random2 and random3):

//*[contains(text(),'match')]

This XPATH 2.0 solution uses the matches() function and a regex pattern that looks for text nodes that contain 'match' and begin at the start of the string(i.e. ^) or a word boundary (i.e. \W) and terminated by the end of the string (i.e. $) or a word boundary. The third parameter i evaluates the regex pattern case-insensitive. (matches random2)

//*[matches(text(),'(^|\W)match($|\W)','i')]

Multiprogramming-More than on job in main memory.

Muntitasking - More than one program run simultaneously. that is more than one program in CPU.

import sys

def write():
    print('Creating new text file') 

    name = raw_input('Enter name of text file: ')+'.txt'  # Name of text file coerced with +.txt

    try:
        file = open(name,'a')   # Trying to create a new file or open one
        file.close()

    except:
        print('Something went wrong! Can\'t tell what?')
        sys.exit(0) # quit Python

write()

this will work promise :)

Finally found out what to do. Added the -std=c++0x compiler argument under Project Properties -> C/C++ Build -> Settings -> GCC C++ Compiler -> Miscellaneous. It works now!

But how to add this flag by default for all C++ projects? Anybody?

To compare strings with wildcards use

if [[ "$stringA" == *$stringB* ]]; then
  # Do something here
else
  # Do Something here
fi

You can use COALESCE in conjunction with NULLIF for a short, efficient solution:

COALESCE( NULLIF(yourField,'') , '0' )

The NULLIF function will return null if yourField is equal to the second value ('' in the example), making the COALESCE function fully working on all cases:

                 QUERY                     |                RESULT 
---------------------------------------------------------------------------------
SELECT COALESCE(NULLIF(null  ,''),'0')     |                 '0'
SELECT COALESCE(NULLIF(''    ,''),'0')     |                 '0'
SELECT COALESCE(NULLIF('foo' ,''),'0')     |                 'foo'

This is the code with two bug fixes. The first bug fix was mentioned by Royi Namir in the comment on the accepted answer to this question. The bug is described on StackOverflow at Bug in Trigger Code. The second one was found by @Fandango68 and fixes columns with multiples words for their names.

To export to different sheets and use custom names, as of SQL Server 2008 R2 this can be done using a combination of grouping, page breaks and the PageName property of the group.

Alternatively, if it's just the single sheet that you'd like to give a specific name, try the InitialPageName property on the report.

For a more detailed explanation, have a look here: http://blog.hoegaerden.be/2011/03/23/where-the-sheets-have-a-name-ssrs-excel-export/

You can call the stat() function and use the S_ISREG() macro on the st_mode field of the stat structure in order to determine if your path points to a regular file:

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>

int is_regular_file(const char *path)
{
    struct stat path_stat;
    stat(path, &path_stat);
    return S_ISREG(path_stat.st_mode);
}

Note that there are other file types besides regular and directory, like devices, pipes, symbolic links, sockets, etc. You might want to take those into account.

select cast (as time(0))

would be a good clause. For example:

(select cast(start_date as time(0))) AS 'START TIME'

Shiva's answer doesn't apply anymore. The API call "/users/{user-id}/follows" is not supported by Instagram for some time (it was disabled in 2016).

For a while you were able to get only your own followers/followings with "/users/self/follows" endpoint, but Instagram disabled that feature in April 2018 (with the Cambridge Analytica issue). You can read about it here.

As far as I know (at this moment) there isn't a service available (official or unofficial) where you can get the followers/followings of a user (even your own).

If any of other solution doesn't fix it, try to override the styles to hide the sort togglers:

.sorting_asc:after, .sorting_desc:after {
  content: "";
}

Using url-loader, described here (SurviveJS - Loading Images), you can then use in your code :

import LogoImg from 'YOUR_PATH/logo.png';

and

<img src={LogoImg}/>

Edit: a precision, images are inlined in the js archive with this technique. It can be worthy for small images, but use the technique wisely.

Just try to without changing anything npm install [email protected] X.X.X is your current version

    namespace DateTimeExample
    {
        using System;

        public static class DateTimeExtension
        {
            public static DateTime GetMonday(this DateTime time)
            {
                if (time.DayOfWeek != DayOfWeek.Monday)
                    return GetMonday(time.AddDays(-1)); //Recursive call

                return time;
            }
        }

        internal class Program
        {
            private static void Main()
            {
                Console.WriteLine(DateTime.Now.GetMonday());
                Console.ReadLine();
            }
        }
    } 

You can use javascript's indexOf function.

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";
if(str1.indexOf(str2) != -1){
   alert(str2 + " found");
}

Try this:

$("div[class]").filter(function() {
    var classNames = this.className.split(/\s+/);
    for (var i=0; i<classNames.length; ++i) {
        if (classNames[i].substr(0, 6) === "apple-") {
            return true;
        }
    }
    return false;
})

It represents the speed of an algorithm in the long run.

To take a literal analogy, you don't care how fast a runner can sprint a 100m dash, or even a 5k run. You care more about marathoners, and preferably ultra marathoners (beyond which the analogy to running breaks down and you have to revert to the metaphorical meaning of "the long run").

You can safely stop reading here.

I'm adding this answer because I'm surprised how mathematical and technical the rest of the answers are. The notion of the "long run" in first sentence is related to the arbitrarily time-consuming computational tasks. Unlike running, which is limited by human capacity, computational tasks can take even more than millions of years for certain algorithms to complete.

What about all those mathematical logarithms and polynomials? It turns out that algorithms are intrinsically related to these mathematical terms. If you are measuring the heights of all the kids on the block, it will take you as much time as there are kids. This is intrinsically related to the notion of n^1 or just n where n is nothing more than the number of kids on the block. In the ultra-marathon case, you are measuring the heights of all the kids in your city, but you then have to ignore travel times and assume they are all available to you in a line (otherwise we jump ahead of the current explanation).

Suppose then you are trying to arrange the list that you made of of kids heights in order of shortest height to longest height. If it is just the kids in your neighborhood you might just eyeball it and come up with the ordered list. This is the "sprint" analogy, and we truly don't care about sprints in computer science because why use a computer when you can eyeball something?

But if you were arranging the list of the heights of all kids in your city, or better yet, your country, then you will find that how you do it is intrinsically tied to the mathematical log and n^2. Going through your list to find the shortest kid, writing his name in a separate notebook, and crossing it out from the original notebook is intrinsically tied to the mathematical n^2. If you think of arranging half your notebook, then the other half, and then combining the results, you will arrive at a method that is intrinsically tied to the logarithm.

Finally, suppose you first had to go to the store to buy a measuring tape. This is an example of an effort that is of consequence in short sprints, such as measuring the kids on the block, but when you are measuring all the kids in the city you can safely ignore this cost. This is the intrinsic connection to the mathematical dropping of say lower order polynomial terms.

I hope I have explained that the big-O notation is merely about the long run, that the mathematics is inherently connected to ways of computation, and that the dropping of mathematical terms and other simplifications are connected to the long run in a rather common sense way.

Once you realize this, you'll find the big-O is really super-easy because all the hard high school math just drops out easily. The only difficult part is analyzing an algorithm to identify the mathematical terms, but with some practice you can start dropping terms during the analysis itself and safely ignore chunks of the algorithm to focus only on the part that is relevant to the big-O. I. e. you should be able to eyeball most situations.

Happy big-O-ing, it was my favorite thing about Computer Science -- finding that something was way easier than I thought, and then being able to show off at Google interviews when the uninitiated would be intimidated, lol.

char_seen = []
for char in string:
    if char not in char_seen:
        char_seen.append(char)
print(''.join(char_seen))

This will preserve the order in which alphabets are coming,

output will be

abcd

The first solution is also from http://sed.sourceforge.net/sed1line.txt

$ echo -e '1\n2\n2\n3\n3\n3\n4\n4\n4\n4\n5' |sed -nr '$!N;/^(.*)\n\1$/!P;D'
1
2

5

the core idea is:

print ONLY once of each duplicate consecutive lines at its LAST appearance and use D command to implement LOOP.

Explains:

1. $!N;: if current line is NOT the last line, use N command to read the next line into pattern space.
2. /^(.*)\n\1$/!P: if the contents of current pattern space is two duplicate string separated by \n, which means the next line is the same with current line, we can NOT print it according to our core idea; otherwise, which means current line is the LAST appearance of all of its duplicate consecutive lines, we can now use P command to print the chars in current pattern space util \n (\n also printed).
3. D: we use D command to delete the chars in current pattern space util \n (\n also deleted), then the content of pattern space is the next line.
4. and D command will force sed to jump to its FIRST command $!N, but NOT read the next line from file or standard input stream.

The second solution is easy to understood (from myself):

$ echo -e '1\n2\n2\n3\n3\n3\n4\n4\n4\n4\n5' |sed -nr 'p;:loop;$!N;s/^(.*)\n\1$/\1/;tloop;D'

the core idea is:

print ONLY once of each duplicate consecutive lines at its FIRST appearance and use : command & t command to implement LOOP.

Explains:

1. read a new line from input stream or file and print it once.
2. use :loop command set a label named loop.
3. use N to read next line into the pattern space.
4. use s/^(.*)\n\1$/\1/ to delete current line if the next line is same with current line, we use s command to do the delete action.
5. if the s command is executed successfully, then use tloop command force sed to jump to the label named loop, which will do the same loop to the next lines util there are no duplicate consecutive lines of the line which is latest printed; otherwise, use D command to delete the line which is the same with thelatest-printed line, and force sed to jump to first command, which is the p command, the content of current pattern space is the next new line.

The error TypeError: 'numpy.ndarray' object is not callable means that you tried to call a numpy array as a function.

Use

Z=XY[0]+XY[1]

Instead of

Z=XY(i,0)+XY(i,1)

You can use date to get time and date of a day:

[pengyu@GLaDOS ~]$date
Tue Aug 27 15:01:27 CST 2013

Also hwclock would do:

[pengyu@GLaDOS ~]$hwclock
Tue 27 Aug 2013 03:01:29 PM CST  -0.516080 seconds

For customized output, you can either redirect the output of date to something like awk, or write your own program to do that.

Remember to put your own executable scripts/binary into your PATH (e.g. /usr/bin) to make it invokable anywhere.

Open tmux configuration file with the following command:

vim ~/.tmux.conf

In the configuration file add the following line:

set -g history-limit 5000

Log out and log in again, start a new tmux windows and your limit is 5000 now.

First I recommand you can try use print and observe the action:

for i in range(0, 5, 1):
    print i

the result:

0
1
2
3
4

You can understand the function principle. In fact, range scan range is from 0 to 5-1. It equals 0 <= i < 5

When you really understand for-loop in python, I think its time we get back to business. Let's focus your problem.

You want to use a DECREMENT for-loop in python. I suggest a for-loop tutorial for example.

for i in range(5, 0, -1):
    print i

the result:

5
4
3
2
1

Thus it can be seen, it equals 5 >= i > 0

You want to implement your java code in python:

for (int index = last-1; index >= posn; index--)

It should code this:

for i in range(last-1, posn-1, -1)

I created a script to ignore differences in line endings:

It will display the files which are not added to the commit list and were modified (after ignoring differences in line endings). You can add the argument "add" to add those files to your commit.

#!/usr/bin/perl

# Usage: ./gitdiff.pl [add]
#    add : add modified files to git

use warnings;
use strict;

my ($auto_add) = @ARGV;
if(!defined $auto_add) {
    $auto_add = "";
}

my @mods = `git status --porcelain 2>/dev/null | grep '^ M ' | cut -c4-`;
chomp(@mods);
for my $mod (@mods) {
    my $diff = `git diff -b $mod 2>/dev/null`;
    if($diff) {
        print $mod."\n";
        if($auto_add eq "add") {
            `git add $mod 2>/dev/null`;
        }
    }
}

• fix by evandro777 : When the file has space in filename or directory

I'm sorry, I don't know why you get the error message. However, I'm using Java 7 and Windows 10 and the solution for me was to temporarily use Java 8 by changing the JAVA_HOME environment variable. Then I could run mvn install and fetch from Maven Central Repository.

Another similar option that I think Nick briefly alluded to in the comments is to create multiple wrapper jars. I haven't tried it, but I think they could be completely empty other than the manifest file, which should specify the main class to load as well as the inclusion of the MyJar.jar to the classpath.

MyJar1.jar\META-INF\MANIFEST.MF

Manifest-Version: 1.0
Main-Class: com.mycomp.myproj.dir1.MainClass1
Class-Path: MyJar.jar

MyJar2.jar\META-INF\MANIFEST.MF

Manifest-Version: 1.0
Main-Class: com.mycomp.myproj.dir2.MainClass2
Class-Path: MyJar.jar

etc. Then just run it with java -jar MyJar2.jar

another simple approach with modern built-in stuff like PercentRelativeLayout is now available for new users who hit this problem. thanks to android team for release this item.

<android.support.percent.PercentRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
app:layout_widthPercent="50%">

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop" />

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="#55000000"
        android:paddingBottom="15dp"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:paddingTop="15dp"
        android:textColor="@android:color/white" />

</FrameLayout>

and for better performance you can use some stuff like picasso image loader which help you to fill whole width of every image parents. for example in your adapter you should use this:

int width= context.getResources().getDisplayMetrics().widthPixels;
    com.squareup.picasso.Picasso
            .with(context)
            .load("some url")
            .centerCrop().resize(width/2,width/2)
            .error(R.drawable.placeholder)
            .placeholder(R.drawable.placeholder)
            .into(item.drawableId);

now you dont need CustomImageView Class anymore.

P.S i recommend to use ImageView in place of Type Int in class Item.

hope this help..

Code:

function isInArray(value, array) {
  return array.indexOf(value) > -1;
}

Execution:

isInArray(1, [1,2,3]); // true

Update (2017):

In modern browsers which follow the ECMAScript 2016 (ES7) standard, you can use the function Array.prototype.includes, which makes it way more easier to check if an item is present in an array:

const array = [1, 2, 3];_x000D_
const value = 1;_x000D_
const isInArray = array.includes(value);_x000D_
console.log(isInArray); // true

String to Time (using an arbitrary time):

String myTime = "10:00:00"; 
Time startingTime = new Time (myTime);

String to Time (using currentTime):

String currentTime = getCurrentTime(); 
Time startingTime = new Time (currentTime);

Time to String:

private String getCurrentTime() {    
    SimpleDateFormat dateFormat = new SimpleDateFormat("kkmmss");
    String currentTime = dateFormat.format(System.currentTimeMillis());
    return currentTime;
}

You can use toArray() of eloquent as below.

The toArray method converts the collection into a plain PHP array. If the collection's values are Eloquent models, the models will also be converted to arrays

$comments_collection = $post->comments()->get()->toArray()

From Laravel Docs:

toArray also converts all of the collection's nested objects that are an instance of Arrayable to an array. If you want to get the raw underlying array, use the all method instead.

Quoting the iPhone OS Technology Overview:

iPhone OS provides support for full-screen video playback through the Media Player framework (MediaPlayer.framework). This framework supports the playback of movie files with the .mov, .mp4, .m4v, and .3gp filename extensions and using the following compression standards:

• H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H.264 Baseline Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
• H.264 video, up to 768 Kbps, 320 by 240 pixels, 30 frames per second, Baseline Profile up to Level 1.3 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
• MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
• Numerous audio formats, including the ones listed in “Audio Technologies”

For information about the classes of the Media Player framework, see Media Player Framework Reference.

UPDATE only changes the values you specify:

UPDATE table SET cell='new_value' WHERE whatever='somevalue'

"Not ASCII (neither's ?/?)" needs qualification.

While these characters are not defined in the American Standard Code for Information Interchange as glyphs, their codes WERE commonly used to give a graphical presentation for ASCII codes 24 and 25 (hex 18 and 19, CANcel and EM:End of Medium). Code page 437 (called Extended ASCII by IBM, includes the numeric codes 128 to 255) defined the use of these glyphs as ASCII codes and the ubiquity of these conventions permeated the industry as seen by their deployment as standards by leading companies such as HP, particularly for printers, and IBM, particularly for microcomputers starting with the original PC.

Just as the use of the ASCII codes for CAN and EM was relatively obsolete at the time, justifying their use as glyphs, so has the passage of time made the use of the codes as glyphs obsolete by the current use of UNICODE conventions.

It should be emphasized that the extensions to ASCII made by IBM in Extended ASCII, included not only a larger numeric set for numeric codes 128 to 255, but also extended the use of some numeric control codes, in the ASCII range 0 to 32, from just media transmission control protocols to include glyphs. It is often assumed, incorrectly, that the first 0 to 128 were not "extended" and that IBM was using the glyphs of conventional ASCII for this range. This error is also perpetrated in one of the previous references. This error became so pervasive that it colloquially redefined ASCII subliminally.

In order for the client to be able to read cookies from cross-origin requests, you need to have:

1. All responses from the server need to have the following in their header:

   Access-Control-Allow-Credentials: true

2. The client needs to send all requests with withCredentials: true option

In my implementation with Angular 7 and Spring Boot, I achieved that with the following:

Server-side:

@CrossOrigin(origins = "http://my-cross-origin-url.com", allowCredentials = "true")
@Controller
@RequestMapping(path = "/something")
public class SomethingController {
  ...
}

The origins = "http://my-cross-origin-url.com" part will add Access-Control-Allow-Origin: http://my-cross-origin-url.com to every server's response header

The allowCredentials = "true" part will add Access-Control-Allow-Credentials: true to every server's response header, which is what we need in order for the client to read the cookies

Client-side:

import { HttpInterceptor, HttpXsrfTokenExtractor, HttpRequest, HttpHandler, HttpEvent } from "@angular/common/http";
import { Injectable } from "@angular/core";
import { Observable } from 'rxjs';

@Injectable()
export class CustomHttpInterceptor implements HttpInterceptor {

    constructor(private tokenExtractor: HttpXsrfTokenExtractor) {
    }

    intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        // send request with credential options in order to be able to read cross-origin cookies
        req = req.clone({ withCredentials: true });

        // return XSRF-TOKEN in each request's header (anti-CSRF security)
        const headerName = 'X-XSRF-TOKEN';
        let token = this.tokenExtractor.getToken() as string;
        if (token !== null && !req.headers.has(headerName)) {
            req = req.clone({ headers: req.headers.set(headerName, token) });
        }
        return next.handle(req);
    }
}

With this class you actually inject additional stuff to all your request.

The first part req = req.clone({ withCredentials: true });, is what you need in order to send each request with withCredentials: true option. This practically means that an OPTION request will be send first, so that you get your cookies and the authorization token among them, before sending the actual POST/PUT/DELETE requests, which need this token attached to them (in the header), in order for the server to verify and execute the request.

The second part is the one that specifically handles an anti-CSRF token for all requests. Reads it from the cookie when needed and writes it in the header of every request.

The desired result is something like this:

The method is implicitly defined (i.e. generated by the compiler).

From the JLS:

In addition, if E is the name of an enum type, then that type has the following implicitly declared static methods:

/**
* Returns an array containing the constants of this enum 
* type, in the order they're declared.  This method may be
* used to iterate over the constants as follows:
*
*    for(E c : E.values())
*        System.out.println(c);
*
* @return an array containing the constants of this enum 
* type, in the order they're declared
*/
public static E[] values();

/**
* Returns the enum constant of this type with the specified
* name.
* The string must match exactly an identifier used to declare
* an enum constant in this type.  (Extraneous whitespace 
* characters are not permitted.)
* 
* @return the enum constant with the specified name
* @throws IllegalArgumentException if this enum type has no
* constant with the specified name
*/
public static E valueOf(String name);

Going back to basics why not keep it simple and store the Session value in a hidden html value to pass to your API?

Controller

public ActionResult Index()
        {

            Session["Blah"] = 609;

            YourObject yourObject = new YourObject();
            yourObject.SessionValue = int.Parse(Session["Blah"].ToString());

            return View(yourObject);
        }

cshtml

@model YourObject

@{
    var sessionValue = Model.SessionValue;
}

<input type="hidden" value="@sessionValue" id="hBlah" />

Javascript

$(document).ready(function () {

    var sessionValue = $('#hBlah').val();

    alert(sessionValue);

    /* Now call your API with the session variable */}

}

Add style="width:100%; height:100%;" to the div see what that does

not to the #map_canvas but the main div

example

<body>
    <div style="height:100%; width:100%;">
         <div id="map-canvas"></div>
    </div>
</body> 

There are some other answers on here the explain why this is necessary

I am using the following environment

? python --version; ipython --version; jupyter --version
Python 3.5.2+
5.3.0
5.0.0

and the following aliases work well for me

alias pyspark="PYSPARK_PYTHON=/usr/local/bin/python3 PYSPARK_DRIVER_PYTHON=ipython ~/spark-2.1.1-bin-hadoop2.7/bin/pyspark --packages graphframes:graphframes:0.5.0-spark2.1-s_2.11"    
alias pysparknotebook="PYSPARK_PYTHON=/usr/bin/python3 PYSPARK_DRIVER_PYTHON=jupyter PYSPARK_DRIVER_PYTHON_OPTS='notebook' ~/spark-2.1.1-bin-hadoop2.7/bin/pyspark --packages graphframes:graphframes:0.5.0-spark2.1-s_2.11"

In the notebook, I set up the environment as follows

from pyspark.context import SparkContext
sc = SparkContext.getOrCreate()

The whole point of a class is that you create an instance, and that instance encapsulates a set of data. So it's wrong to say that your variables are global within the scope of the class: say rather that an instance holds attributes, and that instance can refer to its own attributes in any of its code (via self.whatever). Similarly, any other code given an instance can use that instance to access the instance's attributes - ie instance.whatever.

https://github.com/pypa/pip/raw/master/contrib/get-pip.py is probably the right way now.

As of the 3.2 SDK you can access the view property of MPMoviePlayerController, modify its frame and add it to your view hierarchy.

MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:url]];
player.view.frame = CGRectMake(184, 200, 400, 300);
[self.view addSubview:player.view];
[player play];

There's an example here: http://www.devx.com/wireless/Article/44642/1954

Please read the $.ajax documentation, this is a covered topic.

$.ajax({
    url: "test.html",
    error: function(){
        // will fire when timeout is reached
    },
    success: function(){
        //do something
    },
    timeout: 3000 // sets timeout to 3 seconds
});

You can get see what type of error was thrown by accessing the textStatus parameter of the error: function(jqXHR, textStatus, errorThrown) option. The options are "timeout", "error", "abort", and "parsererror".

A different approach, just for kicks:

Console.WriteLine(string.Join("\t", list));

I use this mnemonic:

• Single quotes are for strings (one thing)
• Double quotes are for tables names and column names (two things)

This is not 100% correct according to the specs, but this mnemonic helps me (human being).

You could use pandas.to_datetime() as recommended in the documentation for pandas.read_csv():

If a column or index contains an unparseable date, the entire column or index will be returned unaltered as an object data type. For non-standard datetime parsing, use pd.to_datetime after pd.read_csv.

Demo:

>>> D = {'date': '2013-6-4'}
>>> df = pd.DataFrame(D, index=[0])
>>> df
       date
0  2013-6-4
>>> df.dtypes
date    object
dtype: object
>>> df['date'] = pd.to_datetime(df.date, format='%Y-%m-%d')
>>> df
        date
0 2013-06-04
>>> df.dtypes
date    datetime64[ns]
dtype: object

Here is another solution using only matplotlib.pyplot and numpy packages. It works only for Gaussian fitting. It is based on maximum likelihood estimation and have already been mentioned in this topic. Here is the corresponding code :

# Python version : 2.7.9
from __future__ import division
import numpy as np
from matplotlib import pyplot as plt

# For the explanation, I simulate the data :
N=1000
data = np.random.randn(N)
# But in reality, you would read data from file, for example with :
#data = np.loadtxt("data.txt")

# Empirical average and variance are computed
avg = np.mean(data)
var = np.var(data)
# From that, we know the shape of the fitted Gaussian.
pdf_x = np.linspace(np.min(data),np.max(data),100)
pdf_y = 1.0/np.sqrt(2*np.pi*var)*np.exp(-0.5*(pdf_x-avg)**2/var)

# Then we plot :
plt.figure()
plt.hist(data,30,normed=True)
plt.plot(pdf_x,pdf_y,'k--')
plt.legend(("Fit","Data"),"best")
plt.show()

and here is the output.

I don't know if this applies in this case, but sometimes the file got deleted for unknown reasons, copying it again into the respective folder should resolve the problem.

You can also control optimisations internally with #pragma GCC push_options

#pragma GCC push_options
/* #pragma GCC optimize ("unroll-loops") */     

.... code here .....

#pragma GCC pop_options

Solution for my specific case:

Maybe it has happened because you have installed your apk first by the Google Play (my apk was running OK until I found an error) and then trying to reinstall it from your Android Studio (in order to figure it out), I have a solution:

Go to your phone/tablet. Settings -> Backup & Reset -> Disable Automatic Restore

I hope it works :)

Using obtrusive JavaScript (i.e. inline code) as in your example, you can attach the click event handler to the div element with the onclick attribute like so:

 <div id="some-id" class="some-class" onclick="slideonlyone('sms_box');">
     ...
 </div>

However, the best practice is unobtrusive JavaScript which you can easily achieve by using jQuery's on() method or its shorthand click(). For example:

 $(document).ready( function() {
     $('.some-class').on('click', slideonlyone('sms_box'));
     // OR //
     $('.some-class').click(slideonlyone('sms_box'));
 });

Inside your handler function (e.g. slideonlyone() in this case) you can reference the element that triggered the event (e.g. the div in this case) with the $(this) object. For example, if you need its ID, you can access it with $(this).attr('id').

EDIT

After reading your comment to @fmsf below, I see you also need to dynamically reference the target element to be toggled. As @fmsf suggests, you can add this information to the div with a data-attribute like so:

<div id="some-id" class="some-class" data-target="sms_box">
    ...
</div>

To access the element's data-attribute you can use the attr() method as in @fmsf's example, but the best practice is to use jQuery's data() method like so:

 function slideonlyone() {
     var trigger_id = $(this).attr('id'); // This would be 'some-id' in our example
     var target_id  = $(this).data('target'); // This would be 'sms_box'
     ...
 }

Note how data-target is accessed with data('target'), without the data- prefix. Using data-attributes you can attach all sorts of information to an element and jQuery would automatically add them to the element's data object.

For a project of mine, I needed to create intervals for time-series modeling, and to make the procedure more efficient I created tsmoothie: A python library for time-series smoothing and outlier detection in a vectorized way.

It provides different smoothing algorithms together with the possibility to computes intervals.

Here I use a ConvolutionSmoother but you can also test it others.

import numpy as np
import matplotlib.pyplot as plt
from tsmoothie.smoother import *

x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.2

# operate smoothing
smoother = ConvolutionSmoother(window_len=5, window_type='ones')
smoother.smooth(y)

# generate intervals
low, up = smoother.get_intervals('sigma_interval', n_sigma=2)

# plot the smoothed timeseries with intervals

plt.plot(smoother.data[0], '.k')
plt.fill_between(range(len(smoother.data[0])), low[0], up[0], alpha=0.3)

I point out also that tsmoothie can carry out the smoothing of multiple timeseries in a vectorized way

You can change the default namespace:
-> Project -> XXX Properties...
On Application tab: Default namespace

Other than that:
Ctrl-H
Find: WindowsFormsApplication16
Replace: MyName

If you use a static key, encrypt and decrypt always give the same result;

public static final String CRYPTOR_KEY = "your static key here";
byte[] keyByte = Base64.getDecoder().decode(CRYPTOR_KEY);
key = new SecretKeySpec(keyByte, "AES");

By specifying the column as VARCHAR(500) you've set an explicit 500 character limit. You might not have done this yourself explicitly, but Django has done it for you somewhere. Telling you where is hard when you haven't shown your model, the full error text, or the query that produced the error.

If you don't want one, use an unqualified VARCHAR, or use the TEXT type.

varchar and text are limited in length only by the system limits on column size - about 1GB - and by your memory. However, adding a length-qualifier to varchar sets a smaller limit manually. All of the following are largely equivalent:

column_name VARCHAR(500)

column_name VARCHAR CHECK (length(column_name) <= 500) 

column_name TEXT CHECK (length(column_name) <= 500) 

The only differences are in how database metadata is reported and which SQLSTATE is raised when the constraint is violated.

The length constraint is not generally obeyed in prepared statement parameters, function calls, etc, as shown:

regress=> \x
Expanded display is on.
regress=> PREPARE t2(varchar(500)) AS SELECT $1;
PREPARE
regress=> EXECUTE t2( repeat('x',601) );
-[ RECORD 1 ]-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
?column? | xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

and in explicit casts it result in truncation:

regress=> SELECT repeat('x',501)::varchar(1);
-[ RECORD 1 ]
repeat | x

so I think you are using a VARCHAR(500) column, and you're looking at the wrong table or wrong instance of the database.

Use something like PreRender, it makes static pages of your site so search engines can index it.

Here you can find out for what platforms it is available: https://prerender.io/documentation/install-middleware#asp-net

Use a JSON parser, like JSON.NET

string json = "{ \"Atlantic/Canary\": \"GMT Standard Time\", \"Europe/Lisbon\": \"GMT Standard Time\", \"Antarctica/Mawson\": \"West Asia Standard Time\", \"Etc/GMT+3\": \"SA Eastern Standard Time\", \"Etc/GMT+2\": \"UTC-02\", \"Etc/GMT+1\": \"Cape Verde Standard Time\", \"Etc/GMT+7\": \"US Mountain Standard Time\", \"Etc/GMT+6\": \"Central America Standard Time\", \"Etc/GMT+5\": \"SA Pacific Standard Time\", \"Etc/GMT+4\": \"SA Western Standard Time\", \"Pacific/Wallis\": \"UTC+12\", \"Europe/Skopje\": \"Central European Standard Time\", \"America/Coral_Harbour\": \"SA Pacific Standard Time\", \"Asia/Dhaka\": \"Bangladesh Standard Time\", \"America/St_Lucia\": \"SA Western Standard Time\", \"Asia/Kashgar\": \"China Standard Time\", \"America/Phoenix\": \"US Mountain Standard Time\", \"Asia/Kuwait\": \"Arab Standard Time\" }";
var data = (JObject)JsonConvert.DeserializeObject(json);
string timeZone = data["Atlantic/Canary"].Value<string>();

An array is a variable, so in that case mapfile will work

mapfile y <<'z'
abc'asdf"
$(dont-execute-this)
foo"bar"''
z

Then you can print like this

printf %s "${y[@]}"

All the highlighted solutions are using recursion (which is performance costly). Here is cleaner way without recursion:

public T GetControlByType<T>(Control root, Func<T, bool> predicate = null) where T : Control 
{
    if (root == null) {
        throw new ArgumentNullException("root");
    }

    var stack = new Stack<Control>(new Control[] { root });

    while (stack.Count > 0) {
        var control = stack.Pop();
        T match = control as T;

        if (match != null && (predicate == null || predicate(match))) {
            return match;
        }

        foreach (Control childControl in control.Controls) {
           stack.Push(childControl);
        }
    }

    return default(T);
}

You can also use a classic for loop:

import pandas as pd
df = pd.read_csv('your_file.csv')

count = 0
for i in df['a_column']:
    count = count + 1

print(count)

Since API 26, you can generate your HASH KEYS using the following code in KOTLIN without any need of Facebook SDK.

fun generateSSHKey(context: Context){
    try {
        val info = context.packageManager.getPackageInfo(context.packageName, PackageManager.GET_SIGNATURES)
        for (signature in info.signatures) {
            val md = MessageDigest.getInstance("SHA")
            md.update(signature.toByteArray())
            val hashKey = String(Base64.getEncoder().encode(md.digest()))
            Log.i("AppLog", "key:$hashKey=")
        }
    } catch (e: Exception) {
        Log.e("AppLog", "error:", e)
    }

}

Start by registering your custom browser/uploader when you instantiate CKEditor.

<script type="text/javascript">
CKEDITOR.replace('content', {

Ck-editor documentation is not clear after doing alot of R&D for custom file upload finally i have found this solution. It work for me and i hope it will helpful to others as well.

You can import a csv file to this website(https://www.tablesgenerator.com/latex_tables) and click copy to clipboard.

As you've tagged this jQuery ...

First, put IDs on your input buttons and remove the inline handlers:

<input type="number" id="input" />
<input type="button" id="stop" value="stop"/>
<input type="button" id="start" value="start"/>

Then keep all of your state and functions encapsulated in a closure:

EDIT updated for a cleaner implementation, that also addresses @Esailija's concerns about use of setInterval().

$(function() {
    var timer = null;
    var input = document.getElementById('input');

    function tick() {
        ++input.value;
        start();        // restart the timer
    };

    function start() {  // use a one-off timer
        timer = setTimeout(tick, 1000);
    };

    function stop() {
        clearTimeout(timer);
    };

    $('#start').bind("click", start); // use .on in jQuery 1.7+
    $('#stop').bind("click", stop);

    start();  // if you want it to auto-start
});

This ensures that none of your variables leak into global scope, and can't be modified from outside.

(Updated) working demo at http://jsfiddle.net/alnitak/Q6RhG/

It's pretty simple

#Opening file
f= open('sample.txt')
#reading everything in file
r=f.read()
#reading at particular index
r=f.read(1)
#print
print(r)

If you really want to type ToString inside your query, you could write an expression tree visitor that rewrites the call to ToString with a call to the appropriate StringConvert function:

using System.Linq;
using System.Data.Entity.SqlServer;
using System.Linq.Expressions;
using static System.Linq.Expressions.Expression;
using System;

namespace ToStringRewriting {
    class ToStringRewriter : ExpressionVisitor {
        static MethodInfo stringConvertMethodInfo = typeof(SqlFunctions).GetMethods()
                 .Single(x => x.Name == "StringConvert" && x.GetParameters()[0].ParameterType == typeof(decimal?));

        protected override Expression VisitMethodCall(MethodCallExpression node) {
            var method = node.Method;
            if (method.Name=="ToString") {
                if (node.Object.GetType() == typeof(string)) { return node.Object; }
                node = Call(stringConvertMethodInfo, Convert(node.Object, typeof(decimal?));
            }
            return base.VisitMethodCall(node);
        }
    }
    class Person {
        string Name { get; set; }
        long SocialSecurityNumber { get; set; }
    }
    class Program {
        void Main() {
            Expression<Func<Person, Boolean>> expr = x => x.ToString().Length > 1;
            var rewriter = new ToStringRewriter();
            var finalExpression = rewriter.Visit(expr);
            var dcx = new MyDataContext();
            var query = dcx.Persons.Where(finalExpression);

        }
    }
}

You may do....in easy way...within one line Logic

#include <stdio.h>

int main()
{
    int a, b;
    printf("Enter A :");
    scanf("%d",&a);
    printf("Enter B :");
    scanf("%d",&b);
    int a = 1,b = 2;
    a=a^b^(b=a);
    printf("\nValue of A=%d B=%d ",a,b);

    return 1;
}

or

#include <stdio.h>

int main()
{
    int a, b;
    printf("Enter A :");
    scanf("%d",&a);
    printf("Enter B :");
    scanf("%d",&b);
    int a = 1,b = 2;
    a=a+b-(b=a);
    printf("\nValue of A=%d B=%d ",a,b);

    return 1;
}

Here is a demo code where there is pagination + Filtering with AngularJS :

https://codepen.io/lamjaguar/pen/yOrVym

JS :

var app=angular.module('myApp', []);

// alternate - https://github.com/michaelbromley/angularUtils/tree/master/src/directives/pagination
// alternate - http://fdietz.github.io/recipes-with-angular-js/common-user-interface-patterns/paginating-through-client-side-data.html

app.controller('MyCtrl', ['$scope', '$filter', function ($scope, $filter) {
    $scope.currentPage = 0;
    $scope.pageSize = 10;
    $scope.data = [];
    $scope.q = '';

    $scope.getData = function () {
      // needed for the pagination calc
      // https://docs.angularjs.org/api/ng/filter/filter
      return $filter('filter')($scope.data, $scope.q)
     /* 
       // manual filter
       // if u used this, remove the filter from html, remove above line and replace data with getData()

        var arr = [];
        if($scope.q == '') {
            arr = $scope.data;
        } else {
            for(var ea in $scope.data) {
                if($scope.data[ea].indexOf($scope.q) > -1) {
                    arr.push( $scope.data[ea] );
                }
            }
        }
        return arr;
       */
    }

    $scope.numberOfPages=function(){
        return Math.ceil($scope.getData().length/$scope.pageSize);                
    }

    for (var i=0; i<65; i++) {
        $scope.data.push("Item "+i);
    }
  // A watch to bring us back to the 
  // first pagination after each 
  // filtering
$scope.$watch('q', function(newValue,oldValue){             if(oldValue!=newValue){
      $scope.currentPage = 0;
  }
},true);
}]);

//We already have a limitTo filter built-in to angular,
//let's make a startFrom filter
app.filter('startFrom', function() {
    return function(input, start) {
        start = +start; //parse to int
        return input.slice(start);
    }
});

HTML :

<div ng-app="myApp" ng-controller="MyCtrl">
  <input ng-model="q" id="search" class="form-control" placeholder="Filter text">
  <select ng-model="pageSize" id="pageSize" class="form-control">
        <option value="5">5</option>
        <option value="10">10</option>
        <option value="15">15</option>
        <option value="20">20</option>
     </select>
  <ul>
    <li ng-repeat="item in data | filter:q | startFrom:currentPage*pageSize | limitTo:pageSize">
      {{item}}
    </li>
  </ul>
  <button ng-disabled="currentPage == 0" ng-click="currentPage=currentPage-1">
        Previous
    </button> {{currentPage+1}}/{{numberOfPages()}}
  <button ng-disabled="currentPage >= getData().length/pageSize - 1" ng-click="currentPage=currentPage+1">
        Next
    </button>
</div>

Python doesn't subscribe to the idea that exceptions should only be used for exceptional cases, in fact the idiom is 'ask for forgiveness, not permission'. This means that using exceptions as a routine part of your flow control is perfectly acceptable, and in fact, encouraged.

This is generally a good thing, as working this way helps avoid some issues (as an obvious example, race conditions are often avoided), and it tends to make code a little more readable.

Imagine you have a situation where you take some user input which needs to be processed, but have a default which is already processed. The try: ... except: ... else: ... structure makes for very readable code:

try:
   raw_value = int(input())
except ValueError:
   value = some_processed_value
else: # no error occured
   value = process_value(raw_value)

Compare to how it might work in other languages:

raw_value = input()
if valid_number(raw_value):
    value = process_value(int(raw_value))
else:
    value = some_processed_value

Note the advantages. There is no need to check the value is valid and parse it separately, they are done once. The code also follows a more logical progression, the main code path is first, followed by 'if it doesn't work, do this'.

The example is naturally a little contrived, but it shows there are cases for this structure.

The simplest way to do this is with a list comprehension:

[s + mystring for s in mylist]

Notice that I avoided using builtin names like list because that shadows or hides the builtin names, which is very much not good.

Also, if you do not actually need a list, but just need an iterator, a generator expression can be more efficient (although it does not likely matter on short lists):

(s + mystring for s in mylist)

These are very powerful, flexible, and concise. Every good python programmer should learn to wield them.

The posts here help me a lot on my way to find a solution for the Uncaught TypeError: Cannot read property 'value' of undefined issue.

There are already here many answers which are correct, but what we don't have here is the combination for 2 answers that i think resolve this issue completely.

function myFunction(field, data){
  if (typeof document.getElementsByName("+field+")[0] != 'undefined'){
  document.getElementsByName("+field+")[0].value=data;
 }
}

The difference is that you make a check(if a property is defined or not) and if the check is true then you can try to assign it a value.

Difference is static variables are those variables: which allows a value to be retained from one call of the function to another. But in case of local variables the scope is till the block/ function lifetime.

For Example:

#include <stdio.h>

void func() {
    static int x = 0; // x is initialized only once across three calls of func()
    printf("%d\n", x); // outputs the value of x
    x = x + 1;
}

int main(int argc, char * const argv[]) {
    func(); // prints 0
    func(); // prints 1
    func(); // prints 2
    return 0;
}

Inline elements can't be transformed, and pseudo elements are inline by default, so you must apply display: block or display: inline-block to transform them:

#whatever:after {
  content: "\24B6";
  display: inline-block;
  transform: rotate(30deg);
}

<div id="whatever">Some text </div>

If you use Visual Studio 2013 and you like use MVC 3, you get this error because Visual Studio 2013 does not support MVC 3 natively (even of you change ./Views/web.config), only MVC 4: https://msdn.microsoft.com/en-us/library/hh266747.aspx

As Chris suggests, you can do it like this:

public string GetXMLAsString(XmlDocument myxml)
{
    return myxml.OuterXml;
}

Or like this:

public string GetXMLAsString(XmlDocument myxml)
    {

        StringWriter sw = new StringWriter();
        XmlTextWriter tx = new XmlTextWriter(sw);
        myxml.WriteTo(tx);

        string str = sw.ToString();// 
        return str;
    }

and if you really want to create a new XmlDocument then do this

XmlDocument newxmlDoc= myxml

There is a case for either solution, depending on what you want to do conditional on the existence of the environment variable.

Case 1

When you want to take different actions purely based on the existence of the environment variable, without caring for its value, the first solution is the best practice. It succinctly describes what you test for: is 'FOO' in the list of environment variables.

if 'KITTEN_ALLERGY' in os.environ:
    buy_puppy()
else:
    buy_kitten()

Case 2

When you want to set a default value if the value is not defined in the environment variables the second solution is actually useful, though not in the form you wrote it:

server = os.getenv('MY_CAT_STREAMS', 'youtube.com')

or perhaps

server = os.environ.get('MY_CAT_STREAMS', 'youtube.com')

Note that if you have several options for your application you might want to look into ChainMap, which allows to merge multiple dicts based on keys. There is an example of this in the ChainMap documentation:

[...]
combined = ChainMap(command_line_args, os.environ, defaults)

It's either through system property

-Dorg.slf4j.simpleLogger.defaultLogLevel=debug

or simplelogger.properties file on the classpath

see http://www.slf4j.org/api/org/slf4j/impl/SimpleLogger.html for details

You can use some methods of the DateTime class, which might be handy; namely, DateTime::createFromFormat() in conjunction with DateTime::getLastErrors().

$test_date = '03/22/2010';

$date = DateTime::createFromFormat('m/d/Y', $test_date);
$date_errors = DateTime::getLastErrors();
if ($date_errors['warning_count'] + $date_errors['error_count'] > 0) {
    $errors[] = 'Some useful error message goes here.';
}

This even allows us to see what actually caused the date parsing warnings/errors (look at the warnings and errors arrays in $date_errors).

sysv-rc-conf is an alternate option for Ubuntu.

sudo apt-get install sysv-rc-conf

sysv-rc-conf --list xxxx

In kotlin

print()

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

println()

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

To find the keycode for any key, use this simple function:

document.onkeydown = function(evt) {
    console.log(evt.keyCode);
}

This question is very old, but I found myself studying for a Microsoft Certification, and in the study book it was suggested to use:

oldElement.replaceNode(newElement)

I looked it up and it seems to only be supported in IE. Doh..

I thought I'd just add it here as a funny side note ;)

I met such problem. Visual Studio 2008 clearly said: problem was caused by libtiff.dll. It cannot be loaded for some reasom, caused by its manifest (as a matter of fact, this dll has no manifest at all). I fixed it, when I had removed libtiff.dll from my project (but simultaneously I lost ability to open compressed TIFFs!). I recompiled aforementioned dll, but problem still remains. Interesting, that at my own machine I have no such error. Three others comps refused to load my prog. Attention!!! Here http://www.error-repair-tools.com/ppc/error.php?t=0xc0150002 one wise boy wrote, that this error was caused by problem with registry and offers repair tool. I have a solid guess, that this "repair tool" will install some malicious soft at your comp.

Try this:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

Importing the namespace is somewhat cleaner. Imagine you have two different modules you import, both of them with the same method/class. Some bad stuff might happen. I'd dare say it is usually good practice to use:

import module

over

from module import function/class

I like to see a green tick in the top right corner in PyCharm. I append the variable names with an underscore just to clear this warning so I can focus on the important warnings.

data = [4, 5, 6]

def print_data(data_):
    print(data_)

print_data(data)

Use git add -A, this will include the deleted files.

Note: use git rm for certain files.

you can intersect types:

type TypeA = {
    nameA: string;
};
type TypeB = {
    nameB: string;
};
export type TypeC = TypeA & TypeB;

somewhere in you code you can now do:

const some: TypeC = {
    nameB: 'B',
    nameA: 'A',
};

I think you are confused about how the compiler puts things together. When you use -c flag, i.e. no linking is done, the input is C++ code, and the output is object code. The .o files thus don't mix with -c, and compiler warns you about that. Symbols from object file are not moved to other object files like that.

All object files should be on the final linker invocation, which is not the case here, so linker (called via g++ front-end) complains about missing symbols.

Here's a small example (calling g++ explicitly for clarity):

PROG ?= myprog
OBJS = worker.o main.o

all: $(PROG)

.cpp.o:
        g++ -Wall -pedantic -ggdb -O2 -c -o $@ $<

$(PROG): $(OBJS)
        g++ -Wall -pedantic -ggdb -O2 -o $@ $(OBJS)

There's also makedepend utility that comes with X11 - helps a lot with source code dependencies. You might also want to look at the -M gcc option for building make rules.

You're looking to create a custom A record.

I'm pretty sure that you can use wildcards when specifying A records which would let you do something like this:

*.mywebsite.com       IN  A       127.0.0.1

127.0.0.1 would be the IP address of your webserver. The method of actually adding the record will depend on your host.

Doing it like http://mywebsite.com/user would be a lot easier to set up if it's an option.

Then you could just add a .htaccess file that looks like this:

Options +FollowSymLinks

RewriteEngine On
RewriteRule ^([aA-zZ])$  dostuff.php?username=$1

In the above, usernames are limited to the characters a-z

The rewrite rule for grabbing the subdomain would look like this:

RewriteCond %{HTTP_HOST} ^(^.*)\.mywebsite.com
RewriteRule (.*)  dostuff.php?username=%1

However, you don't really need any rewrite rules. The HTTP_HOST header is available in PHP as well, so you can get it already, like

$username = strtok($_SERVER['HTTP_HOST'], ".");

If you (already) using a lodash library, there is a function called truncate which can be used for trimming the string.

Based on the example on the docs page

_.truncate('hi-diddly-ho there, neighborino', {
  'length': 24,
  'separator': ' '
});
// => 'hi-diddly-ho there,...'

Note the "" at the beginning and at the end!

Run a program and pass a Long Filename

cmd /c write.exe "c:\sample documents\sample.txt"

Spaces in Program Path

cmd /c ""c:\Program Files\Microsoft Office\Office\Winword.exe""

Spaces in Program Path + parameters

cmd /c ""c:\Program Files\demo.cmd"" Parameter1 Param2

Spaces in Program Path + parameters with spaces

cmd /k ""c:\batch files\demo.cmd" "Parameter 1 with space" "Parameter2 with space""

Launch Demo1 and then Launch Demo2

cmd /c ""c:\Program Files\demo1.cmd" & "c:\Program Files\demo2.cmd""

Add Content-length header describing size of zip file in bytes.

header("Content-type: application/zip"); 
header("Content-Disposition: attachment; filename=$archive_file_name");
header("Content-length: " . filesize($archive_file_name));
header("Pragma: no-cache"); 
header("Expires: 0"); 
readfile("$archive_file_name");

Also make sure that there is absolutely no white space before <? and after ?>. I see a space here:

?

 <?php
$file_names = array('iMUST Operating Manual V1.3a.pdf','iMUST Product Information Sheet.pdf');

Try this:

export PATH=/home/your_username/anaconda3/bin:$PATH
in ~/.bashrc

Then source ~/.bashrc This works for me for the same problem.

Swift

You should always use the system defaults and not hard coding the font name because the default font could be changed by Apple at any time.

There are a couple of system default fonts(normal, bold, italic) with different sizes(label, button, others):

let font = UIFont.systemFont(ofSize: UIFont.systemFontSize)
let font2 = UIFont.boldSystemFont(ofSize: UIFont.systemFontSize)
let font3 = UIFont.italicSystemFont(ofSize: UIFont.systemFontSize)

beaware that the default font size depends on the target view (label, button, others)

Examples:

let labelFont = UIFont.systemFont(ofSize: UIFont.labelFontSize)
let buttonFont = UIFont.systemFont(ofSize: UIFont.buttonFontSize)
let textFieldFont = UIFont.systemFont(ofSize: UIFont.systemFontSize)

Store it in the database in a field with a data type of uniqueidentifier.

The simplest solution I have found is to change the background color programmatically. This does not require dealing with any 9-patch images:

((EditText) findViewById(R.id.id_nick_name)).getBackground()
    .setColorFilter(Color.<your-desi??red-color>, PorterDuff.Mode.MULTIPLY);

If you want to do this without VBA, you can use a combination of IF, ISERROR, and MATCH.

So if all values are in column A, enter this formula in column B:

=IF(ISERROR(MATCH(12345,A:A,0)),"Not Found","Value found on row " & MATCH(12345,A:A,0))

This will look for the value "12345" (which can also be a cell reference). If the value isn't found, MATCH returns "#N/A" and ISERROR tries to catch that.

If you want to use VBA, the quickest way is to use a FOR loop:

Sub FindMatchingValue()
    Dim i as Integer, intValueToFind as integer
    intValueToFind = 12345
    For i = 1 to 500    ' Revise the 500 to include all of your values
        If Cells(i,1).Value = intValueToFind then 
            MsgBox("Found value on row " & i)
            Exit Sub
        End If
    Next i

    ' This MsgBox will only show if the loop completes with no success
    MsgBox("Value not found in the range!")  
End Sub

You can use Worksheet Functions in VBA, but they're picky and sometimes throw nonsensical errors. The FOR loop is pretty foolproof.

And in Bash

 line1=`tail -3 /opt/Scripts/wowzaDataSync.log | grep "AmazonHttpClient" | head -1`
 vpid=`ps -ef|  grep wowzaDataSync | grep -v grep  | awk '{print $2}'`
 echo "-------->"${line1}
    if [ -z $line1 ] && [ ! -z $vpid ]
    then
            echo `date --date "NOW" +%Y-%m-%d` `date --date "NOW" +%H:%M:%S` :: 
            "Process Is Working Fine"
    else
            echo `date --date "NOW" +%Y-%m-%d` `date --date "NOW" +%H:%M:%S` :: 
            "Prcess Hanging Due To Exception With PID :"${pid}
   fi

OR in Bash

line1=`tail -3 /opt/Scripts/wowzaDataSync.log | grep "AmazonHttpClient" | head -1`
vpid=`ps -ef|  grep wowzaDataSync | grep -v grep  | awk '{print $2}'`
echo "-------->"${line1}
   if [ -z $line1 ] || [ ! -z $vpid ]
    then
            echo `date --date "NOW" +%Y-%m-%d` `date --date "NOW" +%H:%M:%S` :: 
            "Process Is Working Fine"
    else
            echo `date --date "NOW" +%Y-%m-%d` `date --date "NOW" +%H:%M:%S` ::

You might also want to define the imeOptions within the EditText. This way, the keyboard will go away once you press on Done:

<EditText
    android:id="@+id/editText1"
    android:inputType="text"
    android:imeOptions="actionDone"/>

Handling the errors

You are binding properties to nothing. :required in

<select class="form-control" v-model="selected" :required @change="changeLocation">

and :selected in

<option :selected>Choose Province</option>

If you set the code like so, your errors should be gone:

<template>
  <select class="form-control" v-model="selected" :required @change="changeLocation">
    <option>Choose Province</option>
    <option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>
 </select>
</template>

Getting the select tags to have a default value

1. you would now need to have a data property called selected so that v-model works. So,

   {
     data () {
       return {
         selected: "Choose Province"
       }
     }
   }
   

2. If that seems like too much work, you can also do it like:

   <template>
     <select class="form-control" :required="true" @change="changeLocation">
      <option :selected="true">Choose Province</option>
      <option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>
     </select>
   </template>
   

When to use which method?

1. You can use the v-model approach if your default value depends on some data property.

2. You can go for the second method if your default selected value happens to be the first option.

3. You can also handle it programmatically by doing so:

   <select class="form-control" :required="true">
     <option 
      v-for="option in options" 
      v-bind:value="option.id"
      :selected="option == '<the default value you want>'"
     >{{ option }}</option>
   </select>
   

An answer that shouldn't be overlooked, because it's simple and presents advantages, is sampling of real life photos and paintings. sample as many random pixels as you want random colors on thumbnails of modern art pics, cezanne, van gogh, monnet, photos... the advantage is that you can get colors by theme and that they are organic colors. just put 20 - 30 pics in a folder and random sample a random pic every time.

Conversion to HSV values is a widespread code algorithm for psychologically based palette. hsv is easier to randomize.

var a = 10;

myFunction(a);

function myFunction(a){
   window['a'] = 20; // or window.a
}

alert("Value of 'a' outside the function " + a); //outputs 20

With window['variableName'] or window.variableName you can modify the value of a global variable inside a function.

Yes, you can use File.renameTo(). But remember to have the correct path while renaming it to a new file.

import java.util.Arrays;
import java.util.List;

public class FileRenameUtility {
public static void main(String[] a) {
    System.out.println("FileRenameUtility");
    FileRenameUtility renameUtility = new FileRenameUtility();
    renameUtility.fileRename("c:/Temp");
}

private void fileRename(String folder){
    File file = new File(folder);
    System.out.println("Reading this "+file.toString());
    if(file.isDirectory()){
        File[] files = file.listFiles();
        List<File> filelist = Arrays.asList(files);
        filelist.forEach(f->{
           if(!f.isDirectory() && f.getName().startsWith("Old")){
               System.out.println(f.getAbsolutePath());
               String newName = f.getAbsolutePath().replace("Old","New");
               boolean isRenamed = f.renameTo(new File(newName));
               if(isRenamed)
                   System.out.println(String.format("Renamed this file %s to  %s",f.getName(),newName));
               else
                   System.out.println(String.format("%s file is not renamed to %s",f.getName(),newName));
           }
        });

    }
}

}

HttpClient.get() applies res.json() automatically and returns Observable<HttpResponse<string>>. You no longer need to call this function yourself.

Try writing a Unit Test before writing the method it is going to test.

That will definitely force you to think a little differently about how things are being done. You'll have no idea how the method is going to work, just what it is supposed to do.

You should always be testing the results of the method, not how the method gets those results.

A 2 column layout is a little bit tough to get working in CSS (at least until CSS3 is practical.)

Floating left and right will work to a point, but it won't allow you to extend the background. To make backgrounds stay solid, you'll have to implement a technique known as "faux columns," which basically means your columns themselves won't have a background image. Your 2 columns will be contained inside of a parent tag. This parent tag is given a background image that contains the 2 column colors you want. Make this background only as big as you need it to (if it is a solid color, only make it 1 pixel high) and have it repeat-y. AListApart has a great walkthrough on what is needed to make it work.

http://www.alistapart.com/articles/fauxcolumns/

It's not possible with CSS3. There is a proposed CSS4 selector, $, to do just that, which could look like this (Selecting the li element):

ul $li ul.sub { ... }

See the list of CSS4 Selectors here.

As an alternative, with jQuery, a one-liner you could make use of would be this:

$('ul li:has(ul.sub)').addClass('has_sub');

You could then go ahead and style the li.has_sub in your CSS.

I am using Android Studio 3.3.

Go to View -> Tools Window -> Device File Explorer. Or you can find it on the Bottom Right corner of the Android Studio.

If the Emulator is running, the Device File Explorer will display the File structure on Emulator Storage.

Here you can right click on a Folder and select "Upload" to place the file

I think you should use something like this and it is called Upcasting:

public int multiplyBy2(int x) throws ArithmeticException {
    long result = 2 * (long) x;    
    if (result > Integer.MAX_VALUE || result < Integer.MIN_VALUE){
        throw new ArithmeticException("Integer overflow");
    }
    return (int) result;
}

It is quite reliable source.

Martin's solution above works great, but does not handle .o files that reside in subdirectories. Godric points out that the -MT flag takes care of that problem, but it simultaneously prevents the .o file from being written correctly. The following will take care of both of those problems:

DEPS := $(OBJS:.o=.d)

-include $(DEPS)

%.o: %.c
    $(CC) $(CFLAGS) -MM -MT $@ -MF $(patsubst %.o,%.d,$@) $<
    $(CC) $(CFLAGS) -o $@ $<

101 is a style argument.

T-SQL Cast / Convert date to string

If you take a look at @types/node-fetch you will see the body definition

export class Body {
    bodyUsed: boolean;
    body: NodeJS.ReadableStream;
    json(): Promise<any>;
    json<T>(): Promise<T>;
    text(): Promise<string>;
    buffer(): Promise<Buffer>;
}

That means that you could use generics in order to achieve what you want. I didn't test this code, but it would looks something like this:

import { Actor } from './models/actor';

fetch(`http://swapi.co/api/people/1/`)
      .then(res => res.json<Actor>())
      .then(res => {
          let b:Actor = res;
      });

Open https://www.google-analytics.com/analytics.js file in a new tab, copy all the code.

Now create a folder in your web directory, rename it to google-analytics.

Create a text file in the same folder and paste all the code you copied above.

Rename the file ga-local.js

Now change the URL to call your locally hosted Analytics Script file in your Google Analytics Code. It will look something like this i.e. https://domain.xyz/google-analytics/ga.js

Finally, place your NEW google analytics code into the footer of your webpage.

You are good to go. Now check your website of Google PageSpeed Insights. It will not show the warning for Leverage Browser Caching Google Analytics. And the only problem with this solution is, to regularly update the Analytics Script manually.

Since the jar file 'executes' then it contains compiled java files known as .class files. You cannot import it to eclipse and modify the code. You should ask the supplier of the "demo" for the "source code". (or check the page you got the demo from for the source code)

Unless, you want to decompile the .class files and import to Eclipse. That may not be the case for starters.

use a cursor

ADDENDUM: [MS SQL cursor example]

declare @field1 int
declare @field2 int
declare cur CURSOR LOCAL for
    select field1, field2 from sometable where someotherfield is null

open cur

fetch next from cur into @field1, @field2

while @@FETCH_STATUS = 0 BEGIN

    --execute your sproc on each row
    exec uspYourSproc @field1, @field2

    fetch next from cur into @field1, @field2
END

close cur
deallocate cur

in MS SQL, here's an example article

note that cursors are slower than set-based operations, but faster than manual while-loops; more details in this SO question

ADDENDUM 2: if you will be processing more than just a few records, pull them into a temp table first and run the cursor over the temp table; this will prevent SQL from escalating into table-locks and speed up operation

ADDENDUM 3: and of course, if you can inline whatever your stored procedure is doing to each user ID and run the whole thing as a single SQL update statement, that would be optimal

You need to copy the string into another, not read-only memory buffer and modify it there. Use strncpy() for copying the string, strlen() for detecting string length, malloc() and free() for dynamically allocating a buffer for the new string.

For example (C++ like pseudocode):

int stringLength = strlen( sourceString );
char* newBuffer = malloc( stringLength + 1 );

// you should check if newBuffer is 0 here to test for memory allocaton failure - omitted

strncpy( newBuffer, sourceString, stringLength );
newBuffer[stringLength] = 0;

// you can now modify the contents of newBuffer freely

The combination of Sids and Koreys answers worked for me.

Extending the Navigation Controller:

extension UINavigationController {
    public override func shouldAutorotate() -> Bool {
        return visibleViewController.shouldAutorotate()
    }
}

Then disabling rotation on the single View

class ViewController: UIViewController {
    override func shouldAutorotate() -> Bool {
        return false
    }
}

And rotating to the appropriate orientation before the segue

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if (segue.identifier == "SomeSegue")
    {
        let value = UIInterfaceOrientation.Portrait.rawValue;
        UIDevice.currentDevice().setValue(value, forKey: "orientation")
    }
}

• Go to ezwinports, https://sourceforge.net/projects/ezwinports/files/

• Download make-4.2.1-without-guile-w32-bin.zip (get the version without guile)

• Extract zip
• Copy the contents to C:\ProgramFiles\Git\mingw64\ merging the folders, but do NOT overwrite/replace any exisiting files.

If you disable asynchronous retrieval, your script will block until the request has been fulfilled. It's useful for performing some sequence of requests in a known order, though I find async callbacks to be cleaner.

in your PyCharm project:

• press Ctrl+Alt+s to open the settings
• on the left column, select Project Interpreter
• on the top right there is a list of python binaries found on your system, pick the right one
• eventually click the + button to install additional python modules
• validate

Here are the steps:

• Install the subclipse plugin (provides svn connectivity in eclipse) and connect to the repository. Instructions here: http://subclipse.tigris.org/install.html
• Go to File->New->Other->Under the SVN category, select Checkout Projects from SVN.
• Select your project's root folder and select checkout as a project in the workspace.

It seems you are checking the .project file into the source repository. I would suggest not checking in the .project file so users can have their own version of the file. Also, if you use the subclipse plugin it allows you to check out and configure a source folder as a java project. This process creates the correct .project for you(with the java nature),

By default
<Prefix> & for killing a window
<Prefix> x for killing a pane
And you can add config info

vi ~/.tmux.conf
bind-key X kill-session

then
<Prefix> X for killing a session

You can have both TortoiseSVN and the Apache Subversion command line tools installed. I usually install the Apache SVN tools from the VisualSVN download site: https://www.visualsvn.com/downloads/

Once installed, place the Subversion\bin in your set PATH. Then you will be able to use TortoiseSVN when you want to use the GUI, and you have the proper SVN command line tools to use from the command line.

Regarding to the originally error message

cannot be resolved to absolute file path because it does not reside in the file system

The following code could be helpful, to find the solution for the path problem:

Paths.get("message.txt").toAbsolutePath().toString();

With this you can determine, where the application expects the missing file. You can execute this in the main method of your application.

I had a very similar problem and want to share my solution

Given this table (all MySQL 5.6):

There are at least five different ways to rename specific columns in pandas, and I have listed them below along with links to the original answers. I also timed these methods and found them to perform about the same (though YMMV depending on your data set and scenario). The test case below is to rename columns A M N Z to A2 M2 N2 Z2 in a dataframe with columns A to Z containing a million rows.

# Import required modules
import numpy as np
import pandas as pd
import timeit

# Create sample data
df = pd.DataFrame(np.random.randint(0,9999,size=(1000000, 26)), columns=list('ABCDEFGHIJKLMNOPQRSTUVWXYZ'))

# Standard way - https://stackoverflow.com/a/19758398/452587
def method_1():
    df_renamed = df.rename(columns={'A': 'A2', 'M': 'M2', 'N': 'N2', 'Z': 'Z2'})

# Lambda function - https://stackoverflow.com/a/16770353/452587
def method_2():
    df_renamed = df.rename(columns=lambda x: x + '2' if x in ['A', 'M', 'N', 'Z'] else x)

# Mapping function - https://stackoverflow.com/a/19758398/452587
def rename_some(x):
    if x=='A' or x=='M' or x=='N' or x=='Z':
        return x + '2'
    return x
def method_3():
    df_renamed = df.rename(columns=rename_some)

# Dictionary comprehension - https://stackoverflow.com/a/58143182/452587
def method_4():
    df_renamed = df.rename(columns={col: col + '2' for col in df.columns[
        np.asarray([i for i, col in enumerate(df.columns) if 'A' in col or 'M' in col or 'N' in col or 'Z' in col])
    ]})

# Dictionary comprehension - https://stackoverflow.com/a/38101084/452587
def method_5():
    df_renamed = df.rename(columns=dict(zip(df[['A', 'M', 'N', 'Z']], ['A2', 'M2', 'N2', 'Z2'])))

print('Method 1:', timeit.timeit(method_1, number=10))
print('Method 2:', timeit.timeit(method_2, number=10))
print('Method 3:', timeit.timeit(method_3, number=10))
print('Method 4:', timeit.timeit(method_4, number=10))
print('Method 5:', timeit.timeit(method_5, number=10))

Output:

Method 1: 3.650640267
Method 2: 3.163998427
Method 3: 2.998530871
Method 4: 2.9918436889999995
Method 5: 3.2436501520000007

Use the method that is most intuitive to you and easiest for you to implement in your application.

As you have define the id in int type at the database creation, you have to use the same data type in the model class too. And as you have defined the id to auto increment in the database, you have to mention it in the model class by passing value 'GenerationType.AUTO' into the attribute 'strategy' within the annotation @GeneratedValue. Then the code becomes as below.

@Entity
public class Operator{

  @Id
  @GeneratedValue(strategy = GenerationType.AUTO)
  private int id;

  private String username;

  private String password;

  private Integer active;

  //Getters and setters...
}

Possibly:

std::cin.ignore(INT_MAX);

This would read in and ignore everything until EOF. (you can also supply a second argument which is the character to read until (ex: '\n' to ignore a single line).

Also: You probably want to do a: std::cin.clear(); before this too to reset the stream state.

You can index and use a negative sign to drop the 3rd column:

data[,-3]

Or you can list only the first 2 columns:

data[,c("c1", "c2")]
data[,1:2]

Don't forget the comma and referencing data frames works like this: data[row,column]

I used this for Post my object data as Form Data.

const encodeData = require('querystring');

const object = {type: 'Authorization', username: 'test', password: '123456'};

console.log(object);
console.log(encodeData.stringify(object));

1. First, you need to call the owl.autoplay.js.

2. this code works for me : owl.trigger('play.owl.autoplay',[1000]);

create table Customer(
       CustId int primary key,
       CustName varchar(20),
       DOB date);

insert into Customer values(1,'kingle', TO_DATE('1994-12-16 12:00:00', 'yyyy-MM-dd hh:mi:ss'));

Another option, again assuming that "edit" means you want to modify in place:

void topntail(char *str) {
    size_t len = strlen(str);
    assert(len >= 2); // or whatever you want to do with short strings
    memmove(str, str+1, len-2);
    str[len-2] = 0;
}

This modifies the string in place, without generating a new address as pmg's solution does. Not that there's anything wrong with pmg's answer, but in some cases it's not what you want.

You don't need ANY of these other fancy answers. Below is a simplistic example that doesn't have all the Margin, Height, Width properties set in the XAML, but should be enough to show how to get this done at a basic level.

XAML
Build a Window page like you would normally and add your fields to it, say a Label and TextBox control inside a StackPanel:

<StackPanel Orientation="Horizontal">
    <Label Name="lblUser" Content="User Name:" />
    <TextBox Name="txtUser" />
</StackPanel>

Then create a standard Button for Submission ("OK" or "Submit") and a "Cancel" button if you like:

<StackPanel Orientation="Horizontal">
    <Button Name="btnSubmit" Click="btnSubmit_Click" Content="Submit" />
    <Button Name="btnCancel" Click="btnCancel_Click" Content="Cancel" />
</StackPanel>

Code-Behind
You'll add the Click event handler functions in the code-behind, but when you go there, first, declare a public variable where you will store your textbox value:

public static string strUserName = String.Empty;

Then, for the event handler functions (right-click the Click function on the button XAML, select "Go To Definition", it will create it for you), you need a check to see if your box is empty. You store it in your variable if it is not, and close your window:

private void btnSubmit_Click(object sender, RoutedEventArgs e)
{        
    if (!String.IsNullOrEmpty(txtUser.Text))
    {
        strUserName = txtUser.Text;
        this.Close();
    }
    else
        MessageBox.Show("Must provide a user name in the textbox.");
}

Calling It From Another Page
You're thinking, if I close my window with that this.Close() up there, my value is gone, right? NO!! I found this out from another site: http://www.dreamincode.net/forums/topic/359208-wpf-how-to-make-simple-popup-window-for-input/

They had a similar example to this (I cleaned it up a bit) of how to open your Window from another and retrieve the values:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void btnOpenPopup_Click(object sender, RoutedEventArgs e)
    {
        MyPopupWindow popup = new MyPopupWindow();  // this is the class of your other page

        //ShowDialog means you can't focus the parent window, only the popup
        popup.ShowDialog(); //execution will block here in this method until the popup closes

        string result = popup.strUserName;
        UserNameTextBlock.Text = result;  // should show what was input on the other page
    }
}

Cancel Button
You're thinking, well what about that Cancel button, though? So we just add another public variable back in our pop-up window code-behind:

public static bool cancelled = false;

And let's include our btnCancel_Click event handler, and make one change to btnSubmit_Click:

private void btnCancel_Click(object sender, RoutedEventArgs e)
{        
    cancelled = true;
    strUserName = String.Empty;
    this.Close();
}

private void btnSubmit_Click(object sender, RoutedEventArgs e)
{        
    if (!String.IsNullOrEmpty(txtUser.Text))
    {
        strUserName = txtUser.Text;
        cancelled = false;  // <-- I add this in here, just in case
        this.Close();
    }
    else
        MessageBox.Show("Must provide a user name in the textbox.");
}

And then we just read that variable in our MainWindow btnOpenPopup_Click event:

private void btnOpenPopup_Click(object sender, RoutedEventArgs e)
{
    MyPopupWindow popup = new MyPopupWindow();  // this is the class of your other page
    //ShowDialog means you can't focus the parent window, only the popup
    popup.ShowDialog(); //execution will block here in this method until the popup closes

    // **Here we find out if we cancelled or not**
    if (popup.cancelled == true)
        return;
    else
    {
        string result = popup.strUserName;
        UserNameTextBlock.Text = result;  // should show what was input on the other page
    }
}

Long response, but I wanted to show how easy this is using public static variables. No DialogResult, no returning values, nothing. Just open the window, store your values with the button events in the pop-up window, then retrieve them afterwards in the main window function.

This is a very old question, but my answer may help someone.

• In the encrypt method, don't forget to encode your string to Base64
• In the decrypt method, don't forget to decode your string to Base64

Below is the working code

    import java.util.Arrays;
    import java.util.Base64;

    import javax.crypto.Cipher;
    import javax.crypto.SecretKey;
    import javax.crypto.spec.SecretKeySpec;

    public class EncryptionDecryptionUtil {

    public static String encrypt(final String secret, final String data) {


        byte[] decodedKey = Base64.getDecoder().decode(secret);

        try {
            Cipher cipher = Cipher.getInstance("AES");
            // rebuild key using SecretKeySpec
            SecretKey originalKey = new SecretKeySpec(Arrays.copyOf(decodedKey, 16), "AES");
            cipher.init(Cipher.ENCRYPT_MODE, originalKey);
            byte[] cipherText = cipher.doFinal(data.getBytes("UTF-8"));
            return Base64.getEncoder().encodeToString(cipherText);
        } catch (Exception e) {
            throw new RuntimeException(
                    "Error occured while encrypting data", e);
        }

    }

    public static String decrypt(final String secret,
            final String encryptedString) {


        byte[] decodedKey = Base64.getDecoder().decode(secret);

        try {
            Cipher cipher = Cipher.getInstance("AES");
            // rebuild key using SecretKeySpec
            SecretKey originalKey = new SecretKeySpec(Arrays.copyOf(decodedKey, 16), "AES");
            cipher.init(Cipher.DECRYPT_MODE, originalKey);
            byte[] cipherText = cipher.doFinal(Base64.getDecoder().decode(encryptedString));
            return new String(cipherText);
        } catch (Exception e) {
            throw new RuntimeException(
                    "Error occured while decrypting data", e);
        }
    }


    public static void main(String[] args) {

        String data = "This is not easy as you think";
        String key = "---------------------------------";
        String encrypted = encrypt(key, data);
        System.out.println(encrypted);
        System.out.println(decrypt(key, encrypted));
      }
  }

For Generating Key you can use below class

    import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.util.Base64;

import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;

public class SecretKeyGenerator {

    public static void main(String[] args) throws NoSuchAlgorithmException {

        KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");

        SecureRandom secureRandom = new SecureRandom();
        int keyBitSize = 256;
        keyGenerator.init(keyBitSize, secureRandom);

        SecretKey secretKey = keyGenerator.generateKey();

 System.out.println(Base64.getEncoder().encodeToString(secretKey.getEncoded()));
    }

}

Hello was looking for the same, and it could be also

unlist(lapply(mtcars,class))

What the provided links to comparisons/animations do not consider is when the amount of data exceed available memory --- at which point the number of passes over the data, i.e. I/O-costs, dominate the runtime. If you need to do that, read up on "external sorting" which usually cover variants of merge- and heap sorts.

http://corte.si/posts/code/visualisingsorting/index.html and http://corte.si/posts/code/timsort/index.html also have some cool images comparing various sorting algorithms.

I know it's quite late but in case someone needs a simple solution, the cool thing is you can also add the where clause with it:

public static void DeleteWhere<T>(this DbContext db, Expression<Func<T, bool>> filter) where T : class
{
    string selectSql = db.Set<T>().Where(filter).ToString();
    string fromWhere = selectSql.Substring(selectSql.IndexOf("FROM"));
    string deleteSql = "DELETE [Extent1] " + fromWhere;
    db.Database.ExecuteSqlCommand(deleteSql);
}

Note: just tested with MSSQL2008.

Update:

The solution above won't work when EF generates sql statement with parameters, so here's the update for EF5:

public static void DeleteWhere<T>(this DbContext db, Expression<Func<T, bool>> filter) where T : class
{
    var query = db.Set<T>().Where(filter);

    string selectSql = query.ToString();
    string deleteSql = "DELETE [Extent1] " + selectSql.Substring(selectSql.IndexOf("FROM"));

    var internalQuery = query.GetType().GetFields(BindingFlags.NonPublic | BindingFlags.Instance).Where(field => field.Name == "_internalQuery").Select(field => field.GetValue(query)).First();
    var objectQuery = internalQuery.GetType().GetFields(BindingFlags.NonPublic | BindingFlags.Instance).Where(field => field.Name == "_objectQuery").Select(field => field.GetValue(internalQuery)).First() as ObjectQuery;
    var parameters = objectQuery.Parameters.Select(p => new SqlParameter(p.Name, p.Value)).ToArray();

    db.Database.ExecuteSqlCommand(deleteSql, parameters);
}

It requires a little bit of reflection but works well.

Use CRTL+BREAK to suspend execution at any point. You will be put into break mode and can press F5 to continue the execution or F8 to execute the code step-by-step in the visual debugger.

Of course this only works when there is no message box open, so if your VBA code constantly opens message boxes for some reason it will become a little tricky to press the keys at the right moment.

You can even edit most of the code while it is running.

Use Debug.Print to print out messages to the Immediate Window in the VBA editor, that's way more convenient than MsgBox.

Use breakpoints or the Stop keyword to automatically halt execution in interesting areas.

You can use Debug.Assert to halt execution conditionally.

public function getSalary()
    {
        $this->db->select('tbl_salary.*,tbl_employee.empFirstName');
        $this->db->from('tbl_salary');
        $this->db->join('tbl_employee','tbl_employee.empID = strong texttbl_salary.salEmpID');
        $this->db->where('tbl_salary.status',0);
        $query = $this->db->get();
        return $query->result();
    }

Here's a working solution (2019): put this code inside your login logic;

 GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject json, GraphResponse response) {
                    // Application code
                    if (response.getError() != null) {
                        System.out.println("ERROR");
                    } else {
                        System.out.println("Success");
                        String jsonresult = String.valueOf(json);
                        System.out.println("JSON Result" + jsonresult);

                        String fbUserId = json.optString("id");
                        String fbUserFirstName = json.optString("name");
                        String fbUserEmail = json.optString("email");
                        //String fbUserProfilePics = "http://graph.facebook.com/" + fbUserId + "/picture?type=large";
                        Log.d("SignUpActivity", "Email: " + fbUserEmail + "\nName: " + fbUserFirstName + "\nID: " + fbUserId);
                    }
                    Log.d("SignUpActivity", response.toString());
                }
            });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender, birthday");
            request.setParameters(parameters);
            request.executeAsync();
        }

        @Override
        public void onCancel() {
            setResult(RESULT_CANCELED);
            Toast.makeText(SignUpActivity.this, "Login Attempt Cancelled", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onError(FacebookException error) {
            Toast.makeText(SignUpActivity.this, "An Error Occurred", Toast.LENGTH_LONG).show();
            error.printStackTrace();
        }
    });

Combining Günter Zöchbauer's answer with good-old vanilla-JS, here is a directive with two lines of logic that supports (123) 456-7890 format.

Reactive Forms: Plunk

import { Directive, Output, EventEmitter } from "@angular/core";
import { NgControl } from "@angular/forms";

@Directive({
  selector: '[formControlName][phone]',
  host: {
    '(ngModelChange)': 'onInputChange($event)'
  }
})
export class PhoneMaskDirective {

  @Output() rawChange:EventEmitter<string> = new EventEmitter<string>();

  constructor(public model: NgControl) {}

  onInputChange(value) {
        var x = value.replace(/\D/g, '').match(/(\d{0,3})(\d{0,3})(\d{0,4})/);
        var y = !x[2] ? x[1] : '(' + x[1] + ') ' + x[2] + (x[3] ? '-' + x[3] : '');

        this.model.valueAccessor.writeValue(y);
        this.rawChange.emit(rawValue); 
  }
}

Template-driven Forms: Plunk

import { Directive } from "@angular/core";
import { NgControl } from "@angular/forms";

@Directive({
  selector: '[ngModel][phone]',
  host: {
    '(ngModelChange)': 'onInputChange($event)'
  }
})
export class PhoneMaskDirective {

  constructor(public model: NgControl) {}

  onInputChange(value) {
        var x = value.replace(/\D/g, '').match(/(\d{0,3})(\d{0,3})(\d{0,4})/);
        value = !x[2] ? x[1] : '(' + x[1] + ') ' + x[2] + (x[3] ? '-' + x[3] : '');

        this.model.valueAccessor.writeValue(value);       
  }
}

There's an easy way to do that. Very easy. Since I noticed that

$scope.yourModel = [];

removes all $scope.yourModel array list you can do like this

function deleteAnObjectByKey(objects, key) {
    var clonedObjects = Object.assign({}, objects);

     for (var x in clonedObjects)
        if (clonedObjects.hasOwnProperty(x))
             if (clonedObjects[x].id == key)
                 delete clonedObjects[x];

    $scope.yourModel = clonedObjects;
}

The $scope.yourModel will be updated with the clonedObjects.

Hope that helps.

Either you need to use a method which uses a predicate indicating whether to keep going (so it has the break instead) or you need to throw an exception - which is a very ugly approach, of course.

So you could write a forEachConditional method like this:

public static <T> void forEachConditional(Iterable<T> source,
                                          Predicate<T> action) {
    for (T item : source) {
        if (!action.test(item)) {
            break;
        }
    }
}

Rather than Predicate<T>, you might want to define your own functional interface with the same general method (something taking a T and returning a bool) but with names that indicate the expectation more clearly - Predicate<T> isn't ideal here.

Your input fragment

public class SecondFragment extends Fragment  {


    EditText etext;
    Button btn;
    String etex;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.secondfragment, container, false);
        etext = (EditText) v.findViewById(R.id.editText4);
        btn = (Button) v.findViewById(R.id.button);
        btn.setOnClickListener(mClickListener);
        return v;
    }

    View.OnClickListener mClickListener = new View.OnClickListener() {
        @Override
        public void onClick(View v) {


            etex = etext.getText().toString();
            FragmentTransaction transection = getFragmentManager().beginTransaction();
            Viewfragment mfragment = new Viewfragment();
            //using Bundle to send data
            Bundle bundle = new Bundle();
            bundle.putString("textbox", etex);
            mfragment.setArguments(bundle); //data being send to SecondFragment
            transection.replace(R.id.frame, mfragment);
            transection.isAddToBackStackAllowed();
            transection.addToBackStack(null);
            transection.commit();

        }
    };



}

your view fragment

public class Viewfragment extends Fragment {

    TextView txtv;
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.viewfrag,container,false);
        txtv = (TextView)  v.findViewById(R.id.textView4);
        Bundle bundle=getArguments();
        txtv.setText(String.valueOf(bundle.getString("textbox")));
        return v;
    }


}

you can use the following command line:

java -jar -Dspring.profiles.active=[yourProfileName] target/[yourJar].jar

Open config file to edit :

git config --global --edit

Press Insert and remove the setting

and finally type :wq and Enter to save.

There seems to be a really easy solution when dealing with data type issues.

Basically, at the end of Excel connection string, add ;IMEX=1;"

Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\\YOURSERVER\shared\Client Projects\FOLDER\Data\FILE.xls;Extended Properties="EXCEL 8.0;HDR=YES;IMEX=1";

This will resolve data type issues such as columns where values are mixed with text and numbers.

To get to connection property, right click on Excel connection manager below control flow and hit properties. It'll be to the right under solution explorer. Hope that helps.

As of C# 9(.net 5 or .net core 3.1), you may want to use records as it does Value Based Equality.

A[A==NDV]=numpy.nan

A==NDV will produce a boolean array that can be used as an index for A

you can use ajax calls to call different methods without a postback

$.ajax({
    type: "POST",
     url: "@(Url.Action("Action", "Controller"))",
     data: {id: 'id', id1: 'id1' },
     contentType: "application/json; charset=utf-8",
     cache: false,
     async: true,
     success: function (result) {
        //do something
     }
});

Sometimes using row.getLastCellNum() gives you a higher value than what is actually filled in the file.
I used the method below to get the last column index that contains an actual value.

private int getLastFilledCellPosition(Row row) {
        int columnIndex = -1;

        for (int i = row.getLastCellNum() - 1; i >= 0; i--) {
            Cell cell = row.getCell(i);

            if (cell == null || CellType.BLANK.equals(cell.getCellType()) || StringUtils.isBlank(cell.getStringCellValue())) {
                continue;
            } else {
                columnIndex = cell.getColumnIndex();
                break;
            }
        }

        return columnIndex;
    }

var tilllastbackslashregex = new RegExp(/^.*\//);
baseUrl = tilllastbackslashregex.exec(window.location.href);

window.location.href gives the current url address from browser address bar

it can be any thing like https://stackoverflow.com/abc/xyz or https://www.google.com/search?q=abc tilllastbackslashregex.exec() run regex and retun the matched string till last backslash ie https://stackoverflow.com/abc/ or https://www.google.com/ respectively

This command will create two files in /path/to/directory table_name.sql and table_name.txt.

The SQL file will contain the table creation schema and the txt file will contain the records of the mytable table with fields delimited by a comma.

mysqldump -u username -p -t  -T/path/to/directory dbname table_name --fields-terminated-by=','

You are right, there is no datatype in SQL-Server which can hold a list of integers. But what you can do is store a list of integers as a string.

DECLARE @listOfIDs varchar(8000);
SET @listOfIDs = '1,2,3,4';

You can then split the string into separate integer values and put them into a table. Your procedure might already do this.

You can also use a dynamic query to achieve the same outcome:

DECLARE @SQL nvarchar(8000);

SET @SQL = 'SELECT * FROM TabA WHERE TabA.ID IN (' + @listOfIDs + ')';
EXECUTE (@SQL);

Add the line to the .bashrc file in the home directory (create the file if it doesn't exist):

cd ~
touch .bashrc
echo "cd ~/Desktop/repos/" >> .bashrc

Integer is an wrapper class/Object and int is primitive type. This difference plays huge role when you want to store int values in a collection, because they accept only objects as values (until jdk1.4). JDK5 onwards because of autoboxing it is whole different story.

Perhaps use tikz.

Like in other answers, start your span attributes with this:

display:inline-block;  

Now you can use padding more than width:

padding-left:6%;
padding-right:6%;

When you use padding, your color expands to both side (right and left), not just right (like in widht).

It works.

In my PHP I use this check

<?php
if (preg_match(
'/^(?:[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+@(?:(?:(?:[a-zA-Z0-9_](?:[a-zA-Z0-9_\-](?!\.)){0,61}[a-zA-Z0-9_-]?\.)+[a-zA-Z0-9_](?:[a-zA-Z0-9_\-](?!$)){0,61}[a-zA-Z0-9_]?)|(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\]))$/',
"tim'[email protected]"        
)){
    echo "legit email";
} else {
    echo "NOT legit email";
}
?>

try it yourself http://phpfiddle.org/main/code/9av6-d10r

I would do it like this:

Worksheets("EmployeeCosts").Range("B" & var1a).Formula = _
Replace("=SUM(H5:H{SOME_VAR})","{SOME_VAR}",var1a)

In case you have some more complex formula it will be handy

Just put yourRelativeLayout inside ScrollView

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/ScrollView01"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
  ------- here RelativeLayout ------
</ScrollView>

this turns the recursion in to a loop:

def checkNextID(ID):
    global numOfRuns, curRes, lastResult
    while ID < lastResult:
        try:
            numOfRuns += 1
            if numOfRuns % 10 == 0:
                time.sleep(3) # sleep every 10 iterations
            if isValid(ID + 8):
                parseHTML(curRes)
                ID = ID + 8
            elif isValid(ID + 18):
                parseHTML(curRes)
                ID = ID + 18
            elif isValid(ID + 7):
                parseHTML(curRes)
                ID = ID + 7
            elif isValid(ID + 17):
                parseHTML(curRes)
                ID = ID + 17
            elif isValid(ID+6):
                parseHTML(curRes)
                ID = ID + 6
            elif isValid(ID + 16):
                parseHTML(curRes)
                ID = ID + 16
            else:
                ID = ID + 1
        except Exception, e:
            print "somethin went wrong: " + str(e)

I got this error but as undefined due to the way I included js files

Initailly i had

<script src="~/vue/blade-account-update-credit-card-vue.js" asp-append-version="true"></script>
<script src="~/lib/vue/vue_v2.5.16.js"></script>

in the end of my .cshtml page GOT Error Vue not Defined but later I changed it to

<script src="~/lib/vue/vue_v2.5.16.js"></script> 
<script src="~/vue/blade-account-update-credit-card-vue.js" asp-append-version="true"></script>

and magically it worked. So i assume that vue js needs to be loaded on top of the .vue

$('input[type="text"]').get().some(item => item.value !== '');

You can also try copying the file to the SD Card folder, which is a public folder, then you can copy the file to your PC where you can use sqlite to access it.

Here is some code you can use to copy the file from data/data to a public storage folder:

private void copyFile(final Context context) {
    try {
        File sd = Environment.getExternalStorageDirectory();
        File data = Environment.getDataDirectory();

        if (sd.canWrite()) {
            String currentDBPath =
                    context.getDatabasePath(DATABASE_NAME).getAbsolutePath();

            String backupDBPath = "data.db";

            File currentDB = new File(currentDBPath);
            File backupDB = new File(sd, backupDBPath);

            if (currentDB.exists()) {
                FileChannel src = new FileInputStream(currentDB).getChannel();
                FileChannel dst = new FileOutputStream(backupDB).getChannel();
                dst.transferFrom(src, 0, src.size());
                src.close();
                dst.close();
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_INTERNAL_STORAGE" />

def gcdRecur(a, b):
    '''
    a, b: positive integers

    returns: a positive integer, the greatest common divisor of a & b.
    '''
    # Base case is when b = 0
    if b == 0:
        return a

    # Recursive case

If your Destination server is on another cloud or data-center then need to add host-entry of MSDTC service(Destination Server) in your source server.

Try this one if problem doesn't resolved, After enable the MSDTC settings.

You could used simple strtok() function (*)From here. Note that tokens are created on delimiters

#include <stdio.h>
#include <string.h>

int main ()
{
  char str[] ="- This is a string";
  char * pch;
  printf ("Splitting string \"%s\" into tokens:\n",str);
  pch = strtok (str," ,.-");
  while (pch != NULL)
  {
    printf ("%s\n",pch);
    pch = strtok (NULL, " ,.-");
  }
  return 0;
}

You do not have to maintain two different accounts for personal and work. In fact, Github Recommends you maintain a single account and helps you merge both.

PowerShell has aliases for several common commands like echo. Type the following in PowerShell:

Get-Alias echo

to get a response:

CommandType     Name                                               Version    Source
-----------     ----                                               -------    ------
Alias           echo -> Write-Output

Even Get-Alias has an alias gal -> Get-Alias. You could write gal echo to get the alias for echo.

gal echo

Other aliases are listed here: https://docs.microsoft.com/en-us/powershell/scripting/learn/using-familiar-command-names?view=powershell-6

cat dir mount rm cd echo move rmdir chdir erase popd sleep clear h ps sort cls history pushd tee copy kill pwd type del lp r write diff ls ren

Laravel 5.2+ solution.

Model::getQuery()->delete();

Just grab underlying builder with table name and do whatever. Couldn't be any tidier than that.

Laravel 5.6 solution

\App\Model::query()->delete();

My answer is tested on Windows 7 with installation of NetBeans IDE 6.9.1 which has bundled Tomcat version 6.0.26. The instruction may work with other tomcat versions according to my opinion.

If you are starting the Apache Tomcat server from the Servers panel in NetBeans IDE then you shall know that the Catalina base and config files used by NetBeans IDE to start the Tomcat server are kept at a different location.

Steps to know the catalina base directory for your installation:

1. Right click on the Apache Tomcat node in Servers panel and choose properties option in the context menu. This will open a dialog box named Servers.
2. Check the directory name of the field Catalina Base, this is that directory where the current conf/tomcat-users.xml is located and which you want to open and read.
   (In my case it is C:\Users\Tushar Joshi\.netbeans\6.9\apache-tomcat-6.0.26_base )
3. Open this directory in My Computer and go to the conf directory where you will find the actual tomcat-users.xml file used by NetBeans IDE. NetBeans IDE comes configured with one default password with username="ide" and some random password, you may change this username and password if you want or use it for your login also
4. This dialog box also have username and password field which are populated with these default username and password and NetBeans IDE also offers you to open the manager application by right clicking on the manager node under the Apache Tomcat node in Servers panel
5. The only problem with the NetBeans IDE is it tries to open the URL http://localhost:8084/manager/ which shall be http://localhost:8084/manager/html now

The previous explanations are all overly detailed and complicated IMO. Put simply, OAuth 2 delegates security to the HTTPS protocol. OAuth 1 did not require this and consequentially had alternative methods to deal with various attacks. These methods required the application to engage in certain security protocols which are complicated and can be difficult to implement. Therefore, it is simpler to just rely on the HTTPS for security so that application developers dont need to worry about it.

As to your other questions, the answer depends. Some services dont want to require the use of HTTPS, were developed before OAuth 2, or have some other requirement which may prevent them from using OAuth 2. Furthermore, there has been a lot of debate about the OAuth 2 protocol itself. As you can see, Facebook, Google, and a few others each have slightly varying versions of the protocols implemented. So some people stick with OAuth 1 because it is more uniform across the different platforms. Recently, the OAuth 2 protocol has been finalized but we have yet to see how its adoption will take.
