Hello UdayaLakmal,

public class MyApplication extends Application {
    private static MyApplication instance;

    @Override
    public void onCreate() {
        super.onCreate();
        instance = this;
    }

    public static MyApplication getInstance(){
        return instance;
    }

    public void clearApplicationData() {
        File cache = getCacheDir();
        File appDir = new File(cache.getParent());
        if(appDir.exists()){
            String[] children = appDir.list();
            for(String s : children){
                if(!s.equals("lib")){
                    deleteDir(new File(appDir, s));
                    Log.i("TAG", "File /data/data/APP_PACKAGE/" + s +" DELETED");
                }
            }
        }
    }

    public static boolean deleteDir(File dir) {
        if (dir != null && dir.isDirectory()) {
            String[] children = dir.list();
            for (int i = 0; i < children.length; i++) {
                boolean success = deleteDir(new File(dir, children[i]));
                if (!success) {
                    return false;
                }
            }
        }

        return dir.delete();
    }
}

Please check this and let me know...

In my case it was a failed import to eclipse. I had to delete the project from eclipse (without deleting form the filesystem of course) and reimport it. After that the error was gone immediately.

In .Net 2.0 I`m pretty sure about this solution:

public IEnumerable<T> Distinct<T>(IEnumerable<T> source)
{
     List<T> uniques = new List<T>();
     foreach (T item in source)
     {
         if (!uniques.Contains(item)) uniques.Add(item);
     }
     return uniques;
}

You can invert the hash. clients.invert["client_id"=>"2180"] returns "orange"

Use router.go(0) if you use Typescript, and it's asking arguments for the go method.

var js = document.createElement("script");

js.type = "text/javascript";
js.src = jsFilePath;

document.body.appendChild(js);

What you have is correct, but this is more consice:

^[A-Z]{3}$

I've had luck starting chrome with the following switch:

--allow-file-access-from-files

On os x try (re-type the dashes if you copy paste):

open -a 'Google Chrome' --args -allow-file-access-from-files

On other *nix run (not tested)

 google-chrome  --allow-file-access-from-files

or on windows edit the properties of the chrome shortcut and add the switch, e.g.

 C:\ ... \Application\chrome.exe --allow-file-access-from-files

to the end of the "target" path

The defaultdict tool is a container in the collections class of Python. It's similar to the usual dictionary (dict) container, but it has one difference: The value fields' data type is specified upon initialization.

For example:

from collections import defaultdict

d = defaultdict(list)

d['python'].append("awesome")

d['something-else'].append("not relevant")

d['python'].append("language")

for i in d.items():

    print i

This prints:

('python', ['awesome', 'language'])
('something-else', ['not relevant'])

I'm really surprised this answer isn't offered here, I was in search of a solution to this question and I think this is the easiest approach, and more flexible/forgiving...

If you'd like to paste multiple lines from a website/text editor/etc., into bash, regardless of whether it's commands per line or a function or entire script... simply start with a ( and end with a ) and Enter, like in the following example:

If I had the following blob

function hello {
    echo Hello!
}
hello

You can paste and verify in a terminal using bash by:

1. Starting with (

2. Pasting your text, and pressing Enter (to make it pretty)... or not

3. Ending with a ) and pressing Enter

Example:

imac:~ home$ ( function hello {
>     echo Hello!
> }
> hello
> )
Hello!
imac:~ home$ 

The pasted text automatically gets continued with a prepending > for each line. I've tested with multiple lines with commands per line, functions and entire scripts. Hope this helps others save some time!

I found useful debugging information on an Ubuntu 16.04 server by running:

systemctl status cron.service

In my case I was kindly informed I had left a comment '#' off of a remark line:

Aug 18 19:12:01 is-feb19 cron[14307]: Error: bad minute; while reading /etc/crontab
Aug 18 19:12:01 is-feb19 cron[14307]: (*system*) ERROR (Syntax error, this crontab file will be ignored)

Underscores look ugly in package names. For what is worth, in case of names compound of three or more words I use initials (for example: com.company.app.ingresoegresofijo (ingreso/egreso fijo) -> com.company.app.iefijo) and then document the package purpose in package-info.java.

You want to use transform this will return a Series with the index aligned to the df so you can then add it as a new column:

In [74]:

df = pd.DataFrame({'Date': ['2015-05-08', '2015-05-07', '2015-05-06', '2015-05-05', '2015-05-08', '2015-05-07', '2015-05-06', '2015-05-05'], 'Sym': ['aapl', 'aapl', 'aapl', 'aapl', 'aaww', 'aaww', 'aaww', 'aaww'], 'Data2': [11, 8, 10, 15, 110, 60, 100, 40],'Data3': [5, 8, 6, 1, 50, 100, 60, 120]})
?
df['Data4'] = df['Data3'].groupby(df['Date']).transform('sum')
df
Out[74]:
   Data2  Data3        Date   Sym  Data4
0     11      5  2015-05-08  aapl     55
1      8      8  2015-05-07  aapl    108
2     10      6  2015-05-06  aapl     66
3     15      1  2015-05-05  aapl    121
4    110     50  2015-05-08  aaww     55
5     60    100  2015-05-07  aaww    108
6    100     60  2015-05-06  aaww     66
7     40    120  2015-05-05  aaww    121

Use:

#include <iostream>

...

std::cout << std::hex << a;

There are many other options to control the exact formatting of the output number, such as leading zeros and upper/lower case.

How about:

public override int GetHashCode()
{
    return string.Format("{0}_{1}_{2}", prop1, prop2, prop3).GetHashCode();
}

Assuming performance is not an issue :)

To get the currently logged in user:

System.getProperty("user.name"); //platform independent 

and the hostname of the machine:

java.net.InetAddress localMachine = java.net.InetAddress.getLocalHost();
System.out.println("Hostname of local machine: " + localMachine.getHostName());

I like prettyPhoto, IMHO it's the one that looks the best.

You can use this:

var refreshIntervalId = null;
refreshIntervalId = setInterval(checkIfVariableIsSet, 1000);

var checkIfVariableIsSet = function()
{
    if(typeof someVariable !== 'undefined'){
        $('a.play').trigger("click");
        clearInterval(refreshIntervalId);
    }
};

var uriSource = new Uri(@"/WpfApplication1;component/Images/Untitled.png", UriKind.Relative);
foo.Source = new BitmapImage(uriSource);

This will load a image called "Untitled.png" in a folder called "Images" with its "Build Action" set to "Resource" in an assembly called "WpfApplication1".

1. change
   <input type="submit" value="Submit" />
   to
   <input type="submit" value="Submit" name='submit'/>

2. change
   <form method="post" action="<?php echo $PHP_SELF;?>">
   to
   <form method="post" action="">

3. It will perform the code in if only when it is submitted.
4. It will always show the form (html code).
5. what exactly is your question?

I had the same problem in Xcode 8.1 and iOS 10.1. What worked for me was going into Simulator-> Hardware->Keyboard and unchecking Connect Hardware Keyboard.

I'm rusty with structs, so I'm probably missing a few keywords here. But why not start with a global structure with the defaults initialized, copy it to your local variable, then modify it?

An initializer like:

void init_struct( structType * s )
{
   memcopy(s,&defaultValues,sizeof(structType));
}

Then when you want to use it:

structType foo;
init_struct( &foo ); // get defaults
foo.fieldICareAbout = 1; // modify fields
update( &foo ); // pass to function

I was trying to figure out if it's possible to browse the code of an earlier commit like you can on GitHub and it brought me here. I used the information I found here, and after fiddling around with the urls, I actually found a way to browse code of old commits as well.

When you're browsing your code the URL is something like:

https://bitbucket.org/user/repo/src/

and by adding a commit hash at the end like this:

https://bitbucket.org/user/repo/src/a0328cb

You can browse the code at the point of that commit. I don't understand why there's no dropdown box for choosing a commit directly, the feature is already there. Strange.

While working with selected cells as shown by @tbur can be useful, it's also not the only option available.

You can use Range() like so:

If Worksheets("Sheet1").Range("A1").MergeCells Then
  Do something
Else
  Do something else
End If

Or:

If Worksheets("Sheet1").Range("A1:C1").MergeCells Then
  Do something
Else
  Do something else
End If

Alternately, you can use Cells():

If Worksheets("Sheet1").Cells(1, 1).MergeCells Then
  Do something
Else
  Do something else
End If

  public static String getDateTime() {
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MMMM dd, yyyy HH:mm:ss", Locale.getDefault());
        Date date = new Date();
        return simpleDateFormat.format(date);
    }

You could use .keypress().

For example, consider the HTML:

<form>
  <fieldset>
    <input id="target" type="text" value="Hello there" />
  </fieldset>
</form>
<div id="other">
  Trigger the handler
</div>

The event handler can be bound to the input field:

$("#target").keypress(function() {
  alert("Handler for .keypress() called.");
});

I totally agree with Andy; all depends on how you want it to work.

With a Spring Boot one can do the following:

application.properties

values[0]=abc
values[1]=def

Configuration class

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

import java.util.ArrayList;
import java.util.List;

@Component
@ConfigurationProperties
public class Configuration {

    List<String> values = new ArrayList<>();

    public List<String> getValues() {
        return values;
    }

}

This is needed, without this class or without the values in class it is not working.

Spring Boot Application class

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import java.util.List;

@SpringBootApplication
public class SpringBootConsoleApplication implements CommandLineRunner {

    private static Logger LOG = LoggerFactory.getLogger(SpringBootConsoleApplication.class);

    // notice #{} is used instead of ${}
    @Value("#{configuration.values}")
    List<String> values;

    public static void main(String[] args) {
        SpringApplication.run(SpringBootConsoleApplication.class, args);
    }

    @Override
    public void run(String... args) {
        LOG.info("values: {}", values);
    }

}

try like this,

ans = str.split (":");

And you can use two parts of the string like,

ans[0] and ans[1]

Children inherit opacity. It'd be weird and inconvenient if they didn't.

You can use a translucent PNG file for your background image, or use an RGBa (a for alpha) color for your background color.

Example, 50% faded black background:

<div style="background-color:rgba(0, 0, 0, 0.5);">_x000D_
   <div>_x000D_
      Text added._x000D_
   </div>_x000D_
</div>

here is a good way to explain it:

there are two forms of the URI

1 - Builder(ready to be modified, not ready to be used)

2 - Built(not ready to be modified, ready to be used )

You can create a builder by

Uri.Builder builder = new Uri.Builder();

this gonna return a Builder ready to be modified like this:-

builder.scheme("https");
builder.authority("api.github.com");
builder.appendPath("search");
builder.appendPath("repositories");
builder.appendQueryParameter(PARAMETER_QUERY,parameterValue);

but to use it you have to build it first

retrun builder.build();

or however you gonna use it. and then you have built that is already built for you, ready to use but cannot be modified.

Uri built = Uri.parse("your URI goes here");

this is ready to use but if you want to modify it you need to buildUpon()

Uri built = Uri.parse("Your URI goes here")
           .buildUpon(); //now it's ready to be modified
           .buildUpon()
           .appendQueryParameter(QUERY_PARAMATER, parameterValue) 
           //any modification you want to make goes here
           .build(); // you have to build it back cause you are storing it 
                     // as Uri not Uri.builder

now every time you want to modify it you need to buildUpon() and in the end build().

so Uri.Builder is a Builder type that store a Builder in it. Uri is a Built type that store an already built URI in it.

new Uri.Builder(); rerurns a Builder. Uri.parse("your URI goes here") returns a Built.

and with build() you can change it from Builder to Built. buildUpon() you can change it from Built to Builder. Here is what you can do

Uri.Builder builder = Uri.parse("URL").buildUpon();
// here you created a builder, made an already built URI with Uri.parse
// and then change it to builder with buildUpon();
Uri built = builder.build();
//when you want to change your URI, change Builder 
//when you want to use your URI, use Built

and also the opposite:-

Uri built = new Uri.Builder().build();
// here you created a reference to a built URI
// made a builder with new Uri.Builder() and then change it to a built with 
// built();
Uri.Builder builder = built.buildUpon();

hope my answer helped :) <3

You can know how many arguments were passed to your function and you can check if your second argument is a function or not:

function getData (id, parameters, callback) {
  if (arguments.length == 2) { // if only two arguments were supplied
    if (Object.prototype.toString.call(parameters) == "[object Function]") {
      callback = parameters; 
    }
  }
  //...
}

You can also use the arguments object in this way:

function getData (/*id, parameters, callback*/) {
  var id = arguments[0], parameters, callback;

  if (arguments.length == 2) { // only two arguments supplied
    if (Object.prototype.toString.call(arguments[1]) == "[object Function]") {
      callback = arguments[1]; // if is a function, set as 'callback'
    } else {
      parameters = arguments[1]; // if not a function, set as 'parameters'
    }
  } else if (arguments.length == 3) { // three arguments supplied
      parameters = arguments[1];
      callback = arguments[2];
  }
  //...
}

If you are interested, give a look to this article by John Resig, about a technique to simulate method overloading on JavaScript.

See Angular 2: Focus on newly added input element for how to set the focus.

For "on load" use the ngAfterViewInit() lifecycle callback.

One good solution is to run only desired services like this:

docker-compose up --build $(<services.txt)

and services.txt file look like this:

services1 services2, etc

of course if dependancy (depends_on), need to run related services together.

--build is optional, just for example.

There must be more to a Python dictionary than a table lookup on hash(). By brute experimentation I found this hash collision:

>>> hash(1.1)
2040142438
>>> hash(4504.1)
2040142438

Yet it doesn't break the dictionary:

>>> d = { 1.1: 'a', 4504.1: 'b' }
>>> d[1.1]
'a'
>>> d[4504.1]
'b'

Sanity check:

>>> for k,v in d.items(): print(hash(k))
2040142438
2040142438

Possibly there's another lookup level beyond hash() that avoids collisions between dictionary keys. Or maybe dict() uses a different hash.

(By the way, this in Python 2.7.10. Same story in Python 3.4.3 and 3.5.0 with a collision at hash(1.1) == hash(214748749.8).)

So if the issue is you just created a website and your clients or any given ISP DNS is cached and doesn't show new site yet. Yes all the other stuff applies ipconfig reset browser etc. BUT here's an Idea and something I do from time to time. You can set an alternate network ISP's DNS in the tcpip properties on the NIC properties. So if your ISP is say telstra and it hasn't propagated or updated you can specify an alternate service providers dns there. if that isp dns is updated before your native one hey presto you will see new site.But there is lots of other tricks you can do to determine propagation and get mail to work prior to the DNS updating. drop me a line if any one wants to chat.

We can add java folder from

1. Build Path -> Source.
2. click on Add Folder.
3. Select main as the container.
4. click on Create Folder.
5. Enter Folder name as java.
6. Click on Finish

It works fine.

As of October 2015, WP 4.3.1 I have found only two plugins actually affecting image locations as in “folders & subfolders”:

• Custom Upload Dir, but as the name says, just on upload. You can work from your %post_slug% or %categories%, upload your images in the context of these post/pages, and this tool will form subfolders from it. Which is great, SEO-wise.

  Or you just even ignore all that and mandate under “Build a path template” i.e. travels/france/paris-at-night to upload to that subdir of your WP-Uploads folder. (Of course you'd have to keep changing for the uploads to follow. Limiting my overall faith, that this is a stable long-term tool, despite 10.000+ active installs).

• Media File Manager allows to move already uploaded images and changes the paths in posts and pages using them accordingly. Its interface reminds of “Norton Commander 1.0” but it does the job. (Except for folder renames and deletes. So if you want to rename, better move images to a newly namend folder, then manually deleting the old.)

All of the following do NOT do the job:

• WP Media Folder is NOT changing actual direcory location, thus not actually changing paths to your images thus also not affecting image URLs. Despite its name, Folder is just their visualisation of yet-another-taxonomy. I invested $19 to learn that.

• Enhance Media Library is big, free and very popular (wordpress counts 40.000 installs) but is also not changing physical location and (thus) URLs. ? Thus the accepted answer is in my opinion wrong.

• Media File Manager advanced appears gone and is deemed dangerous!

I think you could do it using a specs file.

Under MinGW you could run
gcc -dumpspecs > specs

Where it says

*cpp:
%{posix:-D_POSIX_SOURCE} %{mthreads:-D_MT}

You change it to

*cpp:
%{posix:-D_POSIX_SOURCE} %{mthreads:-D_MT} -std=c++11

And then place it in
/mingw/lib/gcc/mingw32/<version>/specs

I'm sure you could do the same without a MinGW build. Not sure where to place the specs file though.

The folder is probably either /gcc/lib/ or /gcc/.

Use FileInfo.Exists Property:

DirectoryInfo di = new DirectoryInfo(ProcessingDirectory);
FileInfo[] TXTFiles = di.GetFiles("*.xml");
if (TXTFiles.Length == 0)
{
    log.Info("no files present")
}
foreach (var fi in TXTFiles)
    log.Info(fi.Exists);

or File.Exists Method:

string curFile = @"c:\temp\test.txt";
Console.WriteLine(File.Exists(curFile) ? "File exists." : "File does not exist.");

I think it's meant to mean nothing. The wiki says:

"Foo is commonly used with the metasyntactic variables bar and foobar."

EDIT

I want to add the reason that your IF statement seems to not work. When you do an EXISTS on an aggregate, it's always going to be true. It returns a value even if the ID doesn't exist. Sure, it's NULL, but its returning it. Instead, do this:

if exists(select 1 from table where id = 4)

and you'll get to the ELSE portion of your IF statement.

Now, here's a better, set-based solution:

update b
  set code = isnull(a.value, 123)
from #b b
left join (select id, max(value) from #a group by id) a
  on b.id = a.id
where
  b.id = yourid

This has the benefit of being able to run on the entire table rather than individual ids.

I created a small NodeJS script based on donut's answer. Store the following in a file called get-facebook-access-token.js:

const fetch = require('node-fetch');
const open = require('open');

const api_version = 'v9.0';
const app_id = '';
const app_secret = '';
const short_lived_token = '';
const page_name = '';

const getPermanentAccessToken = async () => {
  try {
    const long_lived_access_token = await getLongLivedAccessToken();
    const account_id = await getAccountId(long_lived_access_token);
    const permanent_page_access_token = await getPermanentPageAccessToken(
      long_lived_access_token,
      account_id
    );
    checkExpiration(permanent_page_access_token);
  } catch (reason) {
    console.error(reason);
  }
};

const getLongLivedAccessToken = async () => {
  const response = await fetch(
    `https://graph.facebook.com/${api_version}/oauth/access_token?grant_type=fb_exchange_token&client_id=${app_id}&client_secret=${app_secret}&fb_exchange_token=${short_lived_token}`
  );
  const body = await response.json();
  return body.access_token;
};

const getAccountId = async (long_lived_access_token) => {
  const response = await fetch(
    `https://graph.facebook.com/${api_version}/me?access_token=${long_lived_access_token}`
  );
  const body = await response.json();
  return body.id;
};

const getPermanentPageAccessToken = async (
  long_lived_access_token,
  account_id
) => {
  const response = await fetch(
    `https://graph.facebook.com/${api_version}/${account_id}/accounts?access_token=${long_lived_access_token}`
  );
  const body = await response.json();
  const page_item = body.data.find(item => item.name === page_name);  
  return page_item.access_token;
};

const checkExpiration = (access_token) => {
  open(`https://developers.facebook.com/tools/debug/accesstoken/?access_token=${access_token}&version=${api_version}`);
}

getPermanentAccessToken();

Fill in the constants and then run:

npm install node-fetch
npm install open
node get-facebook-access-token.js

After running the script a page is opened in the browser that shows the token and how long it is valid.

git rm --cached *.FileExtension

This must ignore all files from this extension

Try it ;) Just watch the content of the FrameLayout(@id/tabcontent), because I don't know how it will handle in case of scrolling... In my case it works because I used ListView as the content of my tabs. :) Hope it helps.

For people who searched for php multidimensional array get values and actually want to solve problem comes from getting one column value from a 2 dimensinal array (like me!), here's a much elegant way than using foreach, which is array_column

For example, if I only want to get hotel_name from the below array, and form to another array:

$hotels = [
    [
        'hotel_name' => 'Hotel A',
        'info' => 'Hotel A Info',
    ],
    [
        'hotel_name' => 'Hotel B',
        'info' => 'Hotel B Info',
    ]
];

I can do this using array_column:

$hotel_name = array_column($hotels, 'hotel_name');

print_r($hotel_name); // Which will give me ['Hotel A', 'Hotel B']

For the actual answer for this question, it can also be beautified by array_column and call_user_func_array('array_merge', $twoDimensionalArray);

Let's make the data in PHP:

$hotels = [
    [
        'hotel_name' => 'Hotel A',
        'info' => 'Hotel A Info',
        'rooms' => [
            [
                'room_name' => 'Luxury Room',
                'bed' => 2,
                'boards' => [
                    'board_id' => 1,
                    'price' => 200
                ]
            ],
            [
                'room_name' => 'Non Luxy Room',
                'bed' => 4,
                'boards' => [
                    'board_id' => 2,
                    'price' => 150
                ]
            ],
        ]
    ],
    [
        'hotel_name' => 'Hotel B',
        'info' => 'Hotel B Info',
        'rooms' => [
            [
                'room_name' => 'Luxury Room',
                'bed' => 2,
                'boards' => [
                    'board_id' => 3,
                    'price' => 900
                ]
            ],
            [
                'room_name' => 'Non Luxy Room',
                'bed' => 4,
                'boards' => [
                    'board_id' => 4,
                    'price' => 300
                ]
            ],
        ]
    ]
];

And here's the calculation:

$rooms = array_column($hotels, 'rooms');
$rooms = call_user_func_array('array_merge', $rooms);
$boards = array_column($rooms, 'boards');

foreach($boards as $board){
    $board_id = $board['board_id'];
    $price = $board['price'];
    echo "Board ID is: ".$board_id." and price is: ".$price . "<br/>";
}

Which will give you the following result:

Board ID is: 1 and price is: 200
Board ID is: 2 and price is: 150
Board ID is: 3 and price is: 900
Board ID is: 4 and price is: 300

I am using Angular v11 and was facing this error while trying to lazy load a component (await import('./my-component.component')) and even if import and export were correctly set.

I finally figured out that the solution was deleting the separate dedicated module's file and move the module content inside the component file itself.

rm -r my-component.module.ts

and add module inside my-component.ts (same file)

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

@NgModule({
  imports: [CommonModule],
  declarations: [MyComponent],
})
export class MyComponentModule {}

If you are using Lombok, make sure you have enabled annotation processing.

To return the whole table at once you could change the SELECT to:

SELECT  ...
BULK COLLECT INTO T
FROM    ...

This is only advisable for results that aren't excessively large, since they all have to be accumulated in memory before being returned; otherwise consider the pipelined function as suggested by Charles, or returning a REF CURSOR.

This way works fine for me:

var request = new RestSharp.RestRequest("RESOURCE", RestSharp.Method.POST) { RequestFormat = RestSharp.DataFormat.Json }
                .AddBody(BODY);

var response = Client.Execute(request);

// Handle response errors
HandleResponseErrors(response);

if (Errors.Length == 0)
{ }
else
{ }

Hope this helps! (Although it is a bit late)

Create responsive tables by wrapping any .table with .table-responsive{-sm|-md|-lg|-xl}, making the table scroll horizontally at each max-width breakpoint of up to (but not including) 576px, 768px, 992px, and 1120px, respectively.

just wrap table with .table-responsive{-sm|-md|-lg|-xl}

for example

<div class="table-responsive-md">
    <table class="table">
    </table>
</div>

bootstrap 4 tables

I know it has been a while since this was posted, but I think this will help too. I wanted to count unique values and filter the groups by number of these unique values, this is how I did it:

df.groupby('group').agg(['min','max','count','nunique']).reset_index(drop=False)

The right way for Select2 3.x is:

$('select').select2("enable", false)

This works fine.

OK, the following answer is slightly beyond-scope if you only care about Python 3, but this question is the first Google hit even if you don't specify the Python version, so here's a way that works on both Python 2 and Python 3.

I'm also interpreting the question to be about converting bytes to the str type: that is, bytes-y on Python 2, and Unicode-y on Python 3.

Given that, the best approach I know is:

import six

bytes_to_hex_str = lambda b: ' '.join('%02x' % i for i in six.iterbytes(b))

The following assertion will be true for either Python 2 or Python 3, assuming you haven't activated the unicode_literals future in Python 2:

assert bytes_to_hex_str(b'jkl') == '6a 6b 6c'

(Or you can use ''.join() to omit the space between the bytes, etc.)

I think you have red so many definitions but in the case you still have doubts or In case you are new to programming and want to go deep into this then I will suggest you to watch this video, https://youtu.be/HpJTGW9AwX0 It's just reference to get more info about polymorphism... Hope you get better understanding with this

using Eloquent

$data = array(
    array('user_id'=>'Coder 1', 'subject_id'=> 4096),
    array('user_id'=>'Coder 2', 'subject_id'=> 2048),
    //...
);

Model::insert($data);

According to the latest W3C HTML5 recommendation (which is likely to be the final HTML5 standard) published today, there is no seamless attribute in the iframe element anymore. It seems to have been removed somewhere in the standardization process.

According to caniuse.com no major browser does support this attribute (anymore), so you probably shouldn't use it.

You'll have to strncpy str1 into new_string first then.

For those about to hack:

    public static int GetNativeThreadId(Thread thread)
    {
        var f = typeof(Thread).GetField("DONT_USE_InternalThread",
            BindingFlags.GetField | BindingFlags.NonPublic | BindingFlags.Instance);

        var pInternalThread = (IntPtr)f.GetValue(thread);
        var nativeId = Marshal.ReadInt32(pInternalThread, (IntPtr.Size == 8) ? 548 : 348); // found by analyzing the memory
        return nativeId;
    }

Actually you can use a switch statement with Strings in Java...unfortunately this is a new feature of Java 7, and most people are not using Java 7 yet because it's so new.

Have a look at iconv() or mb_convert_encoding(). Just by the way: why don't utf8_encode() and utf8_decode() work for you?

utf8_decode — Converts a string with ISO-8859-1 characters encoded with UTF-8 to single-byte ISO-8859-1

utf8_encode — Encodes an ISO-8859-1 string to UTF-8

So essentially

$utf8 = 'ÄÖÜ'; // file must be UTF-8 encoded
$iso88591_1 = utf8_decode($utf8);
$iso88591_2 = iconv('UTF-8', 'ISO-8859-1', $utf8);
$iso88591_2 = mb_convert_encoding($utf8, 'ISO-8859-1', 'UTF-8');

$iso88591 = 'ÄÖÜ'; // file must be ISO-8859-1 encoded
$utf8_1 = utf8_encode($iso88591);
$utf8_2 = iconv('ISO-8859-1', 'UTF-8', $iso88591);
$utf8_2 = mb_convert_encoding($iso88591, 'UTF-8', 'ISO-8859-1');

all should do the same - with utf8_en/decode() requiring no special extension, mb_convert_encoding() requiring ext/mbstring and iconv() requiring ext/iconv.

You can also export the database and then use a program like notepad++ to replace words and then inmport aigain.

I tried many of the above suggestions, including SuperSU and couldn't get any to work but found something much simpler that worked for my purposes. In my case, I only wanted to be able to run sqlite at the command prompt. I simply spun up an emulator with an older version of Android (Lollipop) and got root access immediately.

You need to give height for the parent element too! Check out this fiddle.

CSS:

html, body {height: 100%;}

#content, .container-fluid, .span9
{
    border: 1px solid #000;
    overflow-y:auto;
    height:100%;
}?

JavaScript (using jQuery) Way:

$(document).ready(function(){
    $(window).resize(function(){
        $(".fullheight").height($(document).height());
    });
});

TextView tv = new TextView(this);
tv.setText(String.valueOf(number));

or

tv.setText(""+number);

app.use applies the specified middleware to the main app middleware stack. When attaching middleware to the main app stack, the order of attachment matters; if you attach middleware A before middleware B, middleware A will always execute first. You can specify a path for which a particular middleware is applicable. In the below example, “hello world” will always be logged before “happy holidays.”

const express = require('express')
const app = express()

app.use(function(req, res, next) {
  console.log('hello world')
  next()
})

app.use(function(req, res, next) {
  console.log('happy holidays')
  next()
})

public class GoogleSearch {

    public static void main(String[] args) {

        WebDriver driver=new FirefoxDriver();
        driver.get("http://www.google.com");
        driver.findElement(By.xpath("//input[@type='text']")).sendKeys("Cheese");   
        driver.findElement(By.xpath("//button[@name='btnG']")).click();
        driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS); 
        driver.findElement(By.xpath("(//h3[@class='r']/a)[3]")).click();
        driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS); 
    }
}

Try this:

$("#textbox").bind('paste',function() {alert("Change detected!");});

See demo on JSFiddle.

The below steps worked for me for the same issue:

Scenario:

I was trying to add 2 new fields to my existing model for Email functionality. The new fields are "IsEmailVerified" and "ActivationCode"

Steps i have followed:

1.Deleted old migration files under "Migrations" folder which are prevented me to do Update-Database 2.Reverted all my recent changes that i have did on the model

3.Run the below command:

Add-Migration -ConnectionProviderName System.Data.SqlClient -ConnectionString "Data Source=DESKTOP\SQLEXPRESS;Initial Catalog=Custom;Persist Security Info=True;User ID=sa;password=****"

4.Deleted the contents from Up() and Down() methods from migration file and left the methods empty

5.Run the below command:

Update-Database -ConnectionProviderName System.Data.SqlClient -ConnectionString "Data Source=DESKTOP\SQLEXPRESS;Initial Catalog=Custom;Persist Security Info=True;User ID=sa;password="***

6. After executes the above step, model and DB looks sync.

7. Now, i added the new properties in the model

        public bool IsEmailVerified { get; set; }
        public Guid ActivationCode { get; set; }
   

8. Run the below command:

Add-Migration -ConnectionProviderName System.Data.SqlClient -ConnectionString "Data Source=DESKTOP\SQLEXPRESS;Initial Catalog=Custom;Persist Security Info=True;User ID=sa;password="***

9. Now the migration file contains only my recent changes as below:

      public override void Up()
        {
            AddColumn("dbo.UserAccounts", "IsEmailVerified", c => c.Boolean(nullable: false));
            AddColumn("dbo.UserAccounts", "ActivationCode", c => c.Guid(nullable: false));
        }        
        public override void Down()
        {
            DropColumn("dbo.UserAccounts", "ActivationCode");
            DropColumn("dbo.UserAccounts", "IsEmailVerified");
        }
   

10. Run the below command: Update-Database -ConnectionProviderName System.Data.SqlClient -ConnectionString "Data Source=DESKTOP\SQLEXPRESS;Initial Catalog=Custom;Persist Security Info=True;User ID=sa;password="***

11.Now i successfully updated the database with additional columns.

The below is updated table after the recent changes:

Table after the update migration

You are using str methods on an open file object.

You can read the file as a list of lines by simply calling list() on the file object:

with open('goodlines.txt') as f:
    mylist = list(f)

This does include the newline characters. You can strip those in a list comprehension:

with open('goodlines.txt') as f:
    mylist = [line.rstrip('\n') for line in f]

- Abstract class is one which can't be instantiated, i.e. its object cannot be created.

- Abstract method are method's declaration without its definition.

- A Non-abstract class can only have Non-abstract methods.

- An Abstract class can have both the Non-abstract as well as Abstract methods.

- If the Class has an Abstract method then the class must also be Abstract.

- An Abstract method must be implemented by the very first Non-Abstract sub-class.

- Abstract class in Design patterns are used to encapsulate the behaviors that keeps changing.

@since Git 2.4

git push --atomic origin <branch name> <tag>

You can set a very small initial delay-time (e.g. 100) and set it to your desired delay-time within the function:

var delay = 100;_x000D_
_x000D_
function foo() {_x000D_
  console.log("Change initial delay-time to what you want.");_x000D_
  delay = 12000;_x000D_
  setTimeout(foo, delay);_x000D_
}

I had the same issue, but my code was a little bit different.

def new
 @project = Project.new
end

And my form looked like this:

<%= form_for @project do |f| %>
     and so on....
<% end %>

That was totally correct, so I didn't know how to figure it out.

Finally, just adding

url: { projects: :create }

after

<%= form-for @project ...%>

worked for me.

Using the constructor

BigInteger(String val)

Translates the decimal String representation of a BigInteger into a BigInteger.

Javadoc

Perhaps not a major language (unfortunately), but in APL, theres the ?EA operation (stand for Execute Alternate).

Usage: 'Y' ?EA 'X' where X and Y are either code snippets supplied as strings or function names.

If X runs into an error, Y (usually error-handling) will be executed instead.

you have to use this css property,

 position:relative;

use it for your #contentframe div tag

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

I'm quite ashamed that there are so many incorrect or undisclosed partial applicability.

The easiest way to do this is through Chrome or Opera (my examples will use Chrome) using the Console. Enter the following code into the console (generally in 1 line):

var l = document.getElementById('testLink');
for(var i=0; i<5; i++){
  l.click();
}

This will generate the required result

There is a good class that does what you want. It can be downloaded at: http://sourceforge.net/projects/snoopy/

I'd recommend this article on CSS Tricks by Chris Coyier entitled Better Helvetica:

http://css-tricks.com/snippets/css/better-helvetica/

He basically recommends the following declaration for covering all the bases:

body {
    font-family: "HelveticaNeue-Light", "Helvetica Neue Light", "Helvetica Neue", Helvetica, Arial, "Lucida Grande", sans-serif; 
    font-weight: 300;
}

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

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

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

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

No need to worry for incrementing/decrementing numbers using Javascript. Now HTML itself provides an easy way for it.

<input type="number" value="50">

It is that simple.The problem is that it works fine only in some browsers.Mozilla has not yet supported this feature.

This response isn't about macro war, but producing error if no matching platform is found.

#ifdef LINUX_KEY_WORD   
... // linux code goes here.  
#elif WINDOWS_KEY_WORD    
... // windows code goes here.  
#else     
#error Platform not supported
#endif

If #error is not supported, you may use static_assert (C++0x) keyword. Or you may implement custom STATIC_ASSERT, or just declare an array of size 0, or have switch that has duplicate cases. In short, produce error at compile time and not at runtime

For Tensorflow 2.0

import tensorflow as tf

tf.test.is_gpu_available(
    cuda_only=False,
    min_cuda_compute_capability=None

other option is:

tf.config.experimental.list_physical_devices('GPU')

Similar to @caveman's solution

const element = document.getElementById('theelementsid');

if (element) {
    window.scroll({
        top: element.scrollTop,
        behavior: 'smooth',

}

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

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

from multiprocessing import Process, Queue
import time
import sys

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

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

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

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

Slightly Swift Solution 
func setGlobalAppearanceCharacteristics () {
    let navigationBarAppearace = UINavigationBar.appearance()
    navigationBarAppearace.tintColor = UIColor.white
    navigationBarAppearace.barTintColor = UIColor.blue
    navigationBarAppearace.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
    navigationBarAppearace.shadowImage = UIImage()

}

this may help :

[objBtn.titleLabel setFont:[UIFont fontWithName:@“fontname” size:fontsize]];

I've played around with select items before and without overriding the functionality with JavaScript, I don't think it's possible in Chrome. Whether you use a plugin or write your own code, CSS only is a no go for Chrome/Safari and as you said, Firefox is better at dealing with it.

If you want to preserve the details come with ls like file size etc in your output then this should work.

sed "s|<OLDPATH>|<NEWPATH>|g" input_file > output_file

UPDATE your_table
SET your_field = REPLACE(your_field, 'articles/updates/', 'articles/news/')
WHERE your_field LIKE '%articles/updates/%'

Now rows that were like

will be

Try adjusting the code at "SqlDbType" to match your DB type if necessary and use this code:

comm.Parameters.Add("@person",SqlDbType.VarChar).Value=MyName;

or:

comm.Parameters.AddWithValue("@person", Myname);

That should work but remember with Command.Parameters.Add(), you can define the specific SqlDbType and with Command.Parameters.AddWithValue(), it will try get the SqlDbType based on parameter value implicitly which can break sometimes if it can not implicitly convert the datatype.

Hope this helps.

If you use jCanvas library you can use opacity property when drawing. If you need fade effect on top of that, simply redraw with different values.

I have the same problem now , I have foreign key and i need put it as nullable, to solve this problem you should put

    modelBuilder.Entity<Country>()
        .HasMany(c => c.Users)
        .WithOptional(c => c.Country)
        .HasForeignKey(c => c.CountryId)
        .WillCascadeOnDelete(false);

in DBContext class I am sorry for answer you very late :)

__getitem__ can be used to implement "lazy" dict subclasses. The aim is to avoid instantiating a dictionary at once that either already has an inordinately large number of key-value pairs in existing containers, or has an expensive hashing process between existing containers of key-value pairs, or if the dictionary represents a single group of resources that are distributed over the internet.

As a simple example, suppose you have two lists, keys and values, whereby {k:v for k,v in zip(keys, values)} is the dictionary that you need, which must be made lazy for speed or efficiency purposes:

class LazyDict(dict):
    
    def __init__(self, keys, values):
        self.keys = keys
        self.values = values
        super().__init__()
        
    def __getitem__(self, key):
        if key not in self:
            try:
                i = self.keys.index(key)
                self.__setitem__(self.keys.pop(i), self.values.pop(i))
            except ValueError, IndexError:
                raise KeyError("No such key-value pair!!")
        return super().__getitem__(key)

Usage:

>>> a = [1,2,3,4]
>>> b = [1,2,2,3]
>>> c = LazyDict(a,b)
>>> c[1]
1
>>> c[4]
3
>>> c[2]
2
>>> c[3]
2
>>> d = LazyDict(a,b)
>>> d.items()
dict_items([])

My two cents, adding trim to remove the initial whitespaces left in sAc's answer.

var str = 'Hello, World, etc';
var str_array = str.split(',');

for(var i = 0; i < str_array.length; i++) {
   // Trim the excess whitespace.
   str_array[i] = str_array[i].replace(/^\s*/, "").replace(/\s*$/, "");
   // Add additional code here, such as:
   alert(str_array[i]);
}

Edit:

After getting several upvotes on this answer, I wanted to revisit this. If you want to split on comma, and perform a trim operation, you can do it in one method call without any explicit loops due to the fact that split will also take a regular expression as an argument:

'Hello, cruel , world!'.split(/\s*,\s*/);
//-> ["Hello", "cruel", "world!"]

This solution, however, will not trim the beginning of the first item and the end of the last item which is typically not an issue.

And so to answer the question in regards to process in a loop, if your target browsers support ES5 array extras such as the map or forEach methods, then you could just simply do the following:

myStringWithCommas.split(/\s*,\s*/).forEach(function(myString) {
    console.log(myString);
});

Java caches the primitive values from -128 to 127. When we compare two Long objects java internally type cast it to primitive value and compare it. But above 127 the Long object will not get type caste. Java caches the output by .valueOf() method.

This caching works for Byte, Short, Long from -128 to 127. For Integer caching works From -128 to java.lang.Integer.IntegerCache.high or 127, whichever is bigger.(We can set top level value upto which Integer values should get cached by using java.lang.Integer.IntegerCache.high).

 For example:
    If we set java.lang.Integer.IntegerCache.high=500;
    then values from -128 to 500 will get cached and 

    Integer a=498;
    Integer b=499;
    System.out.println(a==b)

    Output will be "true".

Float and Double objects never gets cached.

Character will get cache from 0 to 127

You are comparing two objects. so == operator will check equality of object references. There are following ways to do it.

1) type cast both objects into primitive values and compare

    (long)val3 == (long)val4

2) read value of object and compare

    val3.longValue() == val4.longValue()

3) Use equals() method on object comparison.

    val3.equals(val4);  

To create a new commit that 'undoes' the changes of a past commit, use:

$ git revert <commit-hash>

It's also possible to actually remove a commit from an arbitrary point in the past by rebasing and then resetting, but you really don't want to do that if you have already pushed your commits to another repository (or someone else has pulled from you).

If your previous commit is a merge commit you can run this command

$ git revert -m 1 <commit-hash>

See schacon.github.com/git/howto/revert-a-faulty-merge.txt for proper ways to re-merge an un-merged branch

You can also use INT_MAX:

http://www.cplusplus.com/reference/climits/

it's equivalent to using numeric_limits.

Something like:

>>> l = ['element1\t0238.94', 'element2\t2.3904', 'element3\t0139847']
>>> [i.split('\t', 1)[0] for i in l]
['element1', 'element2', 'element3']

try backgroundPosition:"(-20px 0)"

Just to double check are you referencing this the background position plugin?

Example of it on jsfiddle with the background position plugin.

The script manager must be put onto the page before it is used. This would be directly on the page itself, or alternatively, if you are using them, on the Master Page.

The markup would be;

 <asp:ScriptManager ID="ScriptManager1" runat="server" LoadScriptsBeforeUI="true"
            EnablePartialRendering="true" />

Why not use margin? you can apply all kinds off margins to an element. Not just the whole margin around it.

You should use css classes since this is referencing more than one element and you can use id's for those that you want to be different specifically

i.e:

<style>
.box { height: 50px; background: #0F0; width: 100%; margin-top: 10px; }
#first { margin-top: 20px; }
#second { background: #00F; }
h1.box { background: #F00; margin-bottom: 50px;  }
</style>

<h1 class="box">Hello World</h1>
<div class="box" id="first"></div>
<div class="box" id="second"></div>?

Here is a jsfiddle example:

I simply declared as below in web.xml file and Its working for me :

 <welcome-file-list>
    <welcome-file>/WEB-INF/jsps/index.jsp</welcome-file>
</welcome-file-list>

And NO html/jsp pages present in public directory except static resources(css, js, images). Now I can access my index page with URL like : http://localhost:8080/app/ Its calling /WEB-INF/jsps/index.jsp page. When hosted live in production the final URL looks like https://eisdigital.com/

I understand this is outdated, but I couldn't get the former answers to work very satisfactorily, so I wanted to contribute my method in case any one else encounters the same error mentioned in the comments to BumbleBee's answer.

Mine is based on a simple system command. All you feed the function is the name of your script:

extractRootDir <- function(x) {
    abs <- suppressWarnings(system(paste("find ./ -name",x), wait=T, intern=T, ignore.stderr=T))[1];
    path <- paste("~",substr(abs, 3, length(strsplit(abs,"")[[1]])),sep="");
    ret <- gsub(x, "", path);
    return(ret);
}

setwd(extractRootDir("myScript.R"));

The output from the function would look like "/Users/you/Path/To/Script". Hope this helps anyone else who may have gotten stuck.

To Close a fragment while inside the same fragment

getActivity().onBackPressed();

You can use urllib2 as well:

import urllib2

req = urllib2.Request('http://www.python.org/fish.html')
try:
    resp = urllib2.urlopen(req)
except urllib2.HTTPError as e:
    if e.code == 404:
        # do something...
    else:
        # ...
except urllib2.URLError as e:
    # Not an HTTP-specific error (e.g. connection refused)
    # ...
else:
    # 200
    body = resp.read()

Note that HTTPError is a subclass of URLError which stores the HTTP status code.

If you want to use something similar to the JavaScript, you just need to convert to strings first:

Console.WriteLine(mon.ToString() + "." + da.ToString() + "." + yer.ToString());

But a (much) better way would be to use the format option:

Console.WriteLine("{0}.{1}.{2}", mon, da, yer);

Make sure that both projects are in the same .net version also check copy local property but this should be true as default

Yes, assuming the account has appropriate permissions you can use:

SELECT <...>
FROM A.table1 t1 JOIN B.table2 t2 ON t2.column2 = t1.column1;

You just need to prefix the table reference with the name of the database it resides in.

string connectString = "Data Source=(local);" + "Integrated Security=true";

SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(connectString);

Console.WriteLine("builder.InitialCatalog = " + builder.InitialCatalog);

DATEPART(HOUR, [date]) returns the hour in military time ( 00 to 23 ) If you want 1AM, 3PM etc, you need to case it out:

SELECT Run_Time_Hour =
CASE DATEPART(HOUR, R.date_schedule)
    WHEN 0 THEN  '12AM'
    WHEN 1 THEN   '1AM'
    WHEN 2 THEN   '2AM'
    WHEN 3 THEN   '3AM'
    WHEN 4 THEN   '4AM'
    WHEN 5 THEN   '5AM'
    WHEN 6 THEN   '6AM'
    WHEN 7 THEN   '7AM'
    WHEN 8 THEN   '8AM'
    WHEN 9 THEN   '9AM'
    WHEN 10 THEN '10AM'
    WHEN 11 THEN '11AM'
    WHEN 12 THEN '12PM'
    ELSE CONVERT(varchar, DATEPART(HOUR, R.date_schedule)-12) + 'PM'
END

The chosen answer (and most others) require at least two passes through the list.
Here's a one pass solution which might be a better choice for longer lists.

Edited: To address the two deficiencies pointed out by @John Machin. For (2) I attempted to optimize the tests based on guesstimated probability of occurrence of each condition and inferences allowed from predecessors. It was a little tricky figuring out the proper initialization values for max_val and max_indices which worked for all possible cases, especially if the max happened to be the first value in the list — but I believe it now does.

def maxelements(seq):
    ''' Return list of position(s) of largest element '''
    max_indices = []
    if seq:
        max_val = seq[0]
        for i,val in ((i,val) for i,val in enumerate(seq) if val >= max_val):
            if val == max_val:
                max_indices.append(i)
            else:
                max_val = val
                max_indices = [i]

    return max_indices

I had to manually edit the 2 text files (httpd.conf and httpd-ssl.conf) using the Config button for Apache to run and change in notepad from 80 > 81 and 443 > 444

Using the Xampp UI config manager doesn't save the changes into Apache.

To make the query run faster in big tables where not every line needs to be updated, you can also choose to only update rows that will be modified:

UPDATE dbo.xxx
SET Value = REPLACE(Value, '123', '')
WHERE ID <= 4
AND Value LIKE '%123%'

• Go to ~/.ssh
• Create a file named config(have no extension )

• Open config file & add below codes. (change according to your account)

  1. Account 1

     # account_1
     Host gitlab.com-account_1
     HostName gitlab.com
     User git
     PreferredAuthentications publickey
     IdentityFile ~/.ssh/id_rsa_account_1
     

  2. Account 2

     # Account2
     Host gitlab.com-Account2
     HostName gitlab.com
     User git
     PreferredAuthentications publickey
     IdentityFile ~/.ssh/id_rsa_Account2
     

  3. Account 3

     # Account_3
     Host github.com-Account3
     HostName github.com
     User git
     PreferredAuthentications publickey
     IdentityFile ~/.ssh/id_rsa_Account_3
     

• Add remote url as follows

  1. Account 1

     git remote add origin [email protected]_1:group_name/repo_name.git
     

  2. Account 2

     git remote add origin [email protected]:group_name/repo_name.git
     

  3. Account 3

     git remote add origin github.com-Account3:github_username/repo_name.git
     

Make sure that IdentityFile names are same as you created during ssh key generation.

You can plot several columns at once by supplying a list of column names to the plot's y argument.

df.plot(x="X", y=["A", "B", "C"], kind="bar")

This will produce a graph where bars are sitting next to each other.

In order to have them overlapping, you would need to call plot several times, and supplying the axes to plot to as an argument ax to the plot.

import pandas as pd
import matplotlib.pyplot as plt
import numpy as np

y = np.random.rand(10,4)
y[:,0]= np.arange(10)
df = pd.DataFrame(y, columns=["X", "A", "B", "C"])

ax = df.plot(x="X", y="A", kind="bar")
df.plot(x="X", y="B", kind="bar", ax=ax, color="C2")
df.plot(x="X", y="C", kind="bar", ax=ax, color="C3")

plt.show()

I know this is a bit late - but to be clear:

A string doesn't really have encoding... in .NET the a string is a collection of char objects. Essentially, if it is a string, it has already been decoded.

However if you are reading the contents of a file, which is made of bytes, and wish to convert that to a string, then the file's encoding must be used.

.NET includes encoding and decoding classes for: ASCII, UTF7, UTF8, UTF32 and more.

Most of these encodings contain certain byte-order marks that can be used to distinguish which encoding type was used.

The .NET class System.IO.StreamReader is able to determine the encoding used within a stream, by reading those byte-order marks;

Here is an example:

    /// <summary>
    /// return the detected encoding and the contents of the file.
    /// </summary>
    /// <param name="fileName"></param>
    /// <param name="contents"></param>
    /// <returns></returns>
    public static Encoding DetectEncoding(String fileName, out String contents)
    {
        // open the file with the stream-reader:
        using (StreamReader reader = new StreamReader(fileName, true))
        {
            // read the contents of the file into a string
            contents = reader.ReadToEnd();

            // return the encoding.
            return reader.CurrentEncoding;
        }
    }

You need to define the enum outside of the class.

public enum card_suits
{
    Clubs,
    Hearts,
    Spades,
    Diamonds
}

public class Card
{
     // ...

That being said, you may also want to consider using the standard naming guidelines for Enums, which would be CardSuit instead of card_suits, since Pascal Casing is suggested, and the enum is not marked with the FlagsAttribute, suggesting multiple values are appropriate in a single variable.

Query-strings can be ignored by search engines.

You need ReDim:

m = 5
n = 8
Dim my_array()
ReDim my_array(1 To m, 1 To n)
For i = 1 To m
  For j = 1 To n
    my_array(i, j) = i * j
  Next
Next

For i = 1 To m
  For j = 1 To n
    Cells(i, j) = my_array(i, j)
  Next
Next

As others have pointed out, your actual problem would be better solved with ranges. You could try something like this:

Dim r1 As Range
Dim r2 As Range
Dim ws1 As Worksheet
Dim ws2 As Worksheet

Set ws1 = Worksheets("Sheet1")
Set ws2 = Worksheets("Sheet2")
totalRow = ws1.Range("A1").End(xlDown).Row
totalCol = ws1.Range("A1").End(xlToRight).Column

Set r1 = ws1.Range(ws1.Cells(1, 1), ws1.Cells(totalRow, totalCol))
Set r2 = ws2.Range(ws2.Cells(1, 1), ws2.Cells(totalRow, totalCol))
r2.Value = r1.Value

I don't know any MATLAB and I've never used it, but it seems to me you are dividing. Why? Something like this will be much faster:

d = 1/norm(V)
V1 = V * d

In my case, I messed up the connectionString property in a publish profile, trying to access the wrong database (Initial Catalog). Entity Framework then complains that the entities do not match the database, and rightly so.

There are few steps to be followed (For Windows)

1. Open Git Bash and generate ssh key Paste the text below, substituting in your GitHub email address.

   ssh-keygen -t rsa -b 4096 -C "[email protected]"

   This creates a new ssh key, using the provided email as a label.

   Generating public/private rsa key pair.

   When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location.

   Enter a file in which to save the key (/c/Users/you/.ssh/id_rsa):[Press enter]

   At the prompt, type a secure passphrase. For more information, see "Working with SSH key passphrases".

   Enter passphrase (empty for no passphrase): [Type a passphrase] Enter same passphrase again: [Type passphrase again]

2. Add the key to SSH Agent

   Type the following in Git Bash (99999 is just an example) to see agent is up and running. eval $(ssh-agent -s) Agent pid 99999

   then type this.

   ssh-add ~/.ssh/id_rsa

   then Copy the SSH key to your clipboard using this command

   clip < ~/.ssh/id_rsa.pub

3. Add the SSH Key to the Git Account

   In GitHib site, click on the image on top right corner, and select settings. In the subsequent page, click SSH and GPG keys option. This will open up the SSH key page. Click on the New SSH key. In the "Title" field, add a descriptive label for the new key. Paste your key into the "Key" field.

4. Clone the Repository

   Open VS Code (or any IDE/CLI which has command prompt etc.). Go to the directory in which you want to clone, using cd commands, and type the below line. git config --global github.user yourGitUserName git config --global user.email your_email git clone [email protected]:yourGitUserName/YourRepoName.git

In order to execute multiple programs, I also needed a profiles section:

<profiles>
  <profile>
    <id>traverse</id>
    <activation>
      <property>
        <name>traverse</name>
      </property>
    </activation>
    <build>
      <plugins>
        <plugin>
          <groupId>org.codehaus.mojo</groupId>
          <artifactId>exec-maven-plugin</artifactId>
          <configuration>
            <executable>java</executable>
            <arguments>
              <argument>-classpath</argument>
              <argument>org.dhappy.test.NeoTraverse</argument>

This is then executable as:

mvn exec:exec -Ptraverse

A good practice would be based on readability, e.g.:

string str ("Test string");
for (int index = 0, auto it = str.begin(); it < str.end(); ++it)
   cout << index++ << *it;

Or:

string str ("Test string");
for (int index = 0, auto it = str.begin(); it < str.end(); ++it, ++index)
   cout << index << *it;

Or your original:

string str ("Test string");
int index = 0;
for (auto it = str.begin() ; it < str.end(); ++it, ++index)
   cout << index << *it;

Etc. Whatever is easiest and cleanest to you.

It's not clear there is any one best practice as you'll need a counter variable somewhere. The question seems to be whether where you define it and how it is incremented works well for you.

1. df.iloc[0].head(1) - First data set only from entire first row.
2. df.iloc[0] - Entire First row in column.

Be aware this is definitely one way to do it:

$ sudo apt-get install phantomjs
$ phantomjs -v
1.6.0

Sadly, it installs 1.6 and not the latest one, but this works for my purposes.

You have code that is compliled into some IL (intermediate language). When you run your program, the computer doesn't understand this code. It only understands native code. So the JIT compiler compiles your IL into native code on the fly. It does this at the method level.

The ls utility should conform to IEEE Std 1003.1-2001 (POSIX.1) which states:

22027: it shall sort directory and non-directory operands separately according to the collating sequence in the current locale.

26027: By default, the format is unspecified, but the output shall be sorted alphabetically by symbol name:

• Library or object name, if -A is specified
• Symbol name
• Symbol type
• Value of the symbol
• The size associated with the symbol, if applicable

You can give a try to Apache Commons Collections.

There is a class CollectionUtils that allows you to select or filter items by custom Predicate.

Your code would be like this:

Predicate condition = new Predicate() {
   boolean evaluate(Object sample) {
        return ((Sample)sample).value3.equals("three");
   }
};
List result = CollectionUtils.select( list, condition );

Update:

In java8, using Lambdas and StreamAPI this should be:

List<Sample> result = list.stream()
     .filter(item -> item.value3.equals("three"))
     .collect(Collectors.toList());

much nicer!

It's trying to run it as a shell script, which interprets your <?php token as bash, which is a syntax error. Just use include() or one of its friends:

For example, in a.php put:

<?php
print "one";
include 'b.php';
print "three";
?>

In b.php put:

<?php
print "two";
?>

Prints:

eric@dev ~ $ php a.php

SkipSoft.net has some great toolkits. I ran into a similar problem with my Galaxy Nexus.... Ran the corresponding toolkit, which configured my system and downloaded the correct drivers. I then went into Windows Hardware manager after connecting the phone... Windows reported the exclamation that it couldn't find the device driver, so I ran update, and gave it the drivers directory the toolkit had created... and everything started working great. Hope this helps :)

This solution works for both physical devices and iOS simulator in a way that simulator returns the same model as physical device would return for a model e.g. "iPhone10,6" for iPhone X (GSM) rather than "x86_64".

How do I tell Facebook which image to use when my page gets shared?

Facebook has a set of open-graph meta tags that it looks at to decide which image to show.

The keys one for the Facebook image are:

<meta property="og:image" content="http://ia.media-imdb.com/rock.jpg"/>
<meta property="og:image:secure_url" content="https://secure.example.com/ogp.jpg" />

and it should be present inside the <head></head> tag at the top of your page.

If these tags are not present, it will look for their older method of specifying an image: <link rel="image_src" href="/myimage.jpg"/>. If neither are present, Facebook will look at the content of your page and choose images from your page that meet its share image criteria: Image must be at least 200px by 200px, have a maximum aspect ratio of 3:1, and in PNG, JPEG or GIF format.

Can I specify multiple images to allow the user to select an image?

Yes, you just need to add multiple image meta tags in the order you want them to appear in. The user will then be presented with an image selector dialog:

I specified the appropriate image meta tags. Why isn't Facebook accepting the changes?

Once a url has been shared, Facebook's crawler, which has a user agent of facebookexternalhit/1.1 (+https://www.facebook.com/externalhit_uatext.php), will access your page and cache the meta information. To force Facebook servers to clear the cache, use the Facebook Url Debugger / Linter Tool that they launched in June 2010 to refresh the cache and troubleshoot any meta tag issues on your page.

Also, the images on the page must be publicly accessible to the Facebook crawler. You should specify absolute url's like http://example.com/yourimage.jpg instead of just /yourimage.jpg.

Can I update these meta tags with client side code like Javascript or jQuery? No. Much like search engine crawlers, the Facebook scraper does not execute scripts so whatever meta tags are present when the page is downloaded are the meta tags that are used for image selection.

Adding these tags causes my page to no longer validate. How can I fix this?

You can add the necessary Facebook namespaces to your tag and your page should then pass validation:

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:og="http://ogp.me/ns#"
      xmlns:fb="https://www.facebook.com/2008/fbml">  

Actually, I've got a bit more precise solution, which might be useful if you don't want to change/delete anything else.

Run regedit, and at the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome key you should have a PasswordManagerEnabled property, which probably is set to 0.

Simply change it to 1.

Edit: I tried it on some other computer and it didn't want to work, so I rebooted my computer, made sure Chrome is closed, then changed it in the registry, and finally it worked. So make sure Chrome is closed when you do this.

Since you say that any language is acceptable, the natural choice is PostGIS:

SELECT * FROM places
WHERE ST_DistanceSpheroid(geom, $location, $spheroid) < $max_metres;

If you want to use WGS datum, you should set $spheroid to 'SPHEROID["WGS 84",6378137,298.257223563]'

Assuming that you have indexed places by the geom column, this should be reasonably efficient.

As others have referred, names in Oracle SQL must be less or equal to 30 characters. I would add that this rule applies not only to table names but to field names as well. So there you have it.

PLEASE ENSURE TO USE THE RIGHT VERSION OF PHP. Save yourself some stress :)

If file name has no spaces:

ls -l <dir> | awk '{print $6, " ", $7, " ", $8, " ", $9 }'

This prints as the following format:

 Dec   21   20:03   a1.out
 Dec   21   20:04   a.cpp

If file names have space (you can use the following command for file names with no spaces too, just it looks complicated/ugly than the former):

 ls -l <dir> | awk '{printf ("%s %s %s ",  $6,  $7, $8); for (i=9;   i<=NF; i++){ printf ("%s ", $i)}; printf ("\n")}'

You can also set

-Djava.net.useSystemProxies=true

On Windows and Linux this will use the system settings so you don't need to repeat yourself (DRY)

Scenario: Removing NodeJS when Windows has no Program Entry for your Node installation

I ran into a problem where my version of NodeJS (0.10.26) could NOT be uninstalled nor removed, because Programs & Features in Windows 7 (aka Add/Remove Programs) had no record of my having installed NodeJS... so there was no option to remove it short of manually deleting registry keys and files.

Command to verify your NodeJS version: node --version

I attempted to install the newest recommended version of NodeJS, but it failed at the end of the installation process and rolled back. Multiple versions of NodeJS also failed, and the installer likewise rolled them back as well. I could not upgrade NodeJS from the command line as I did not have SUDO installed.

SOLUTION: After spending several hours troubleshooting the problem, including upgrading NPM, I decided to reinstall the EXACT version of NodeJS on my system, over the top of the existing installation.

That solution worked, and it reinstalled NodeJS without any errors. Better yet, it also added an official entry in Add/Remove Programs dialogue.

Now that Windows was aware of the forgotten NodeJS installation, I was able to uninstall my existing version of NodeJS completely. I then successfully installed the newest recommended release of NodeJS for the Windows platform (version 4.4.5 as of this writing) without a roll-back initiating.

It took me a while to reach sucess, so I am posting this in case it helps anyone else with a similar issue.

As the name suggests, snapshot refers to a state of project and its dependencies at that moment of time. Whenever maven finds a newer SNAPSHOT of the project, it downloads and replaces the older .jar file of the project in the local repository.

Snapshot versions are used for projects under active development. If your project depends on a software component that is under active development, you can depend on a snapshot release, and Maven will periodically attempt to download the latest snapshot from a repository when you run a build.

Very generally speaking:

An API key simply identifies you.

If there is a public/private distinction, then the public key is one that you can distribute to others, to allow them to get some subset of information about you from the api. The private key is for your use only, and provides access to all of your data.

1. Go to IE->Tools->Internet Options.
2. Go to Security tab.
3. Either Enable/Disable the protected mode for all(Internet, Local Intranet, Trusted Sites & Restricted Sites.)

if one wants to use .post() then this will set headers for all future request made with jquery

$.ajaxSetup({
    headers: {
        'Content-Type': 'application/json',
        'Accept': 'application/json'
    }
});

then make your .post() calls as normal.

You can use each for objects too and not just for arrays:

var obj = {
    foo: "bar",
    baz: "quux"
};
jQuery.each(obj, function(name, value) {
    alert(name + ": " + value);
});

This is not really a pure answer to the question, but an intelligent way to work around such problems:

instead of writing a complex file, simply delegate control to for instance a bash script like: makefile

foo : bar.cpp baz.h
    bash script.sh

and script.sh looks like:

for number in 1 2 3 4
do
    ./a.out $number
done

You're missing *s in the last two terms of your expression, so R is interpreting (e.g.) 0.207 (log(DIAM93))^2 as an attempt to call a function named 0.207 ...

For example:

> 1 + 2*(3)
[1] 7
> 1 + 2 (3)

Error: attempt to apply non-function

Your (unreproducible) expression should read:

censusdata_20$AGB93 = WD * exp(-1.239 + 1.980 * log (DIAM93) + 
                              0.207* (log(DIAM93))^2  -
                              0.0281*(log(DIAM93))^3)

Mathematica is the only computer system I know of that allows juxtaposition to be used for multiplication ...

It took me a while, but here's how I made it dynamic. It doesn't depend on a sorted table.

First I started with a column of state names (Column A) and a column of aircraft in each state (Column B). (Row 1 is a header row).

Finding the cell that contains the number of aircraft was:

=MATCH(MAX($B$2:$B$54),$B$2:$B$54,0)+MIN(ROW($B$2:$B$54))-1

I put that into a cell and then gave that cell a name, "StateRow" Then using the tips from above, I wound up with this:

=INDIRECT(ADDRESS(StateRow,1))

This returns the name of the state from the dynamic value in row "StateRow", column 1

Now, as the values in the count column change over time as more data is entered, I always know which state has the most aircraft.

Edit : Now it is documented

<ng-container> to the rescue

The Angular <ng-container> is a grouping element that doesn't interfere with styles or layout because Angular doesn't put it in the DOM.

(...)

The <ng-container> is a syntax element recognized by the Angular parser. It's not a directive, component, class, or interface. It's more like the curly braces in a JavaScript if-block:

  if (someCondition) {
      statement1; 
      statement2;
      statement3;
     }

Without those braces, JavaScript would only execute the first statement when you intend to conditionally execute all of them as a single block. The <ng-container> satisfies a similar need in Angular templates.

Original answer:

According to this pull request :

<ng-container> is a logical container that can be used to group nodes but is not rendered in the DOM tree as a node.

<ng-container> is rendered as an HTML comment.

so this angular template :

<div>
    <ng-container>foo</ng-container>
<div>

will produce this kind of output :

<div>
    <!--template bindings={}-->foo
<div>

So ng-container is useful when you want to conditionaly append a group of elements (ie using *ngIf="foo") in your application but don't want to wrap them with another element.

<div>
    <ng-container *ngIf="true">
        <h2>Title</h2>
        <div>Content</div>
    </ng-container>
</div>

will then produce :

<div>
    <h2>Title</h2>
    <div>Content</div>
</div>

Use OpenFileDialog.SafeFileName

OpenFileDialog.SafeFileName Gets the file name and extension for the file selected in the dialog box. The file name does not include the path.

1. Right-click on your project, select Maven -> Remove Maven Nature.

2. Open you terminal, go to your project folder and do mvn eclipse:clean

3. Right click on your Project and select “Configure -> Convert into Maven Project”

Now you got “Unsupported IClasspathEntry kind=4 Eclipse Scala” disappear.

The query below will result in dd/mm/yy format.

select  LEFT(convert(varchar(10), @date, 103),6) + Right(Year(@date)+ 1,2)

An alternative way to code Brettski's answer, with which I otherwise agree entirely, might be

With New FileSystemObject
    If .FileExists(yourFilePath) Then
        .DeleteFile yourFilepath
    End If
End With

Same effect but fewer (well, none at all) variable declarations.

The FileSystemObject is a really useful tool and well worth getting friendly with. Apart from anything else, for text file writing it can actually sometimes be faster than the legacy alternative, which may surprise a few people. (In my experience at least, YMMV).

If you get your string from stdin().read_line, you have to trim it first.

let my_num: i32 = my_num.trim().parse()
   .expect("please give me correct string number!");

This is because label is an inline element, and is therefore only as big as the text it contains.

The possible is to display your label as a block element like this:

#formItem label {
    display: block;
    text-align: center;
    line-height: 150%;
    font-size: .85em;
}

However, if you want to use the label on the same line with other elements, you either need to set display: inline-block; and give it an explicit width (which doesn't work on most browsers), or you need to wrap it inside a div and do the alignment in the div.

I had a similar problem, I wanted to change the format, but I also wanted the flexibility of being able to change the format in the blade template engine too.

I, therefore, set my model up as the following:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

\Carbon\Carbon::setToStringFormat('d-m-Y');

class User extends Model
{
    protected $dates = [
        'from_date',
    ];
}

The setToStringFormat will set all the dates to use this format for this model.
The advantage of this for me is that I could have the format that I wanted without the mutator, because with the mutator, the attribute is returned as a string meaning that in the blade template I would have to write something like this if I wanted to change the format in the template:

{{ date('Y', strtotime($user->from_date)) }}

Which isn't very clean.

Instead, the attribute is still returned as a Carbon instance, however it is first returned in the desired format.
That means that in the template I could write the following, cleaner, code:

{{ $user->from_date->format('Y') }}

In addition to being able to reformat the Carbon instance, I can also call various Carbon methods on the attribute in the template.

There is probably an oversight to this approach; I'm going to wager it is not a good idea to specify the string format at the top of the model in case it affects other scripts. From what I have seen so far, that has not happened. It has only changed the default Carbon for that model only.

In this instance, it might be a good set the Carbon format back to what it was originally at the bottom of the model script. This is a bodged idea, but it would work for each model to have its own format.
Contrary, if you are having the same format for each model then in your AppServiceProvider instead. That would just keep the code neater and easier to maintain.

I wanted to use Font Awesome 5+ and most answers focus on older versions

For the new Font Awesome 5+ the angular project hasn't been released yet, so if you want to make use of the examples mentioned on the font awesome website atm you need to use a work around. (especially the fas, far classes instead of the fa class)

I've just imported the cdn to Font Awesome 5 in my styles.css. Just added this in case it helps someone find the answer quicker than I did :-)

Code in Style.css

@import "https://use.fontawesome.com/releases/v5.0.7/css/all.css";

I believe the part regarding how to span rows has been answered thoroughly (i.e. by nesting rows), but I also ran into the issue of my nested rows not filling their container. While flexbox and negative margins are an option, a much easier solution is to use the predefined h-50 class on the row containing boxes 2, 3, 4, and 5.

Note: I am using Bootstrap-4, I just wanted to share because I ran into the same problem and found this to be a more elegant solution :)

Long after accept answer.

Use sprintf(), or related functions, as many others have answers suggested, but use a better format specifier.

Using "%.*e", code solves various issues:

• The maximum buffer size needed is far more reasonable, like 18 for float (see below). With "%f", sprintf(buf, "%f", FLT_MAX); could need 47+. sprintf(buf, "%f", DBL_MAX); may need 317+

• Using ".*" allows code to define the number of decimal places needed to distinguish a string version of float x and it next highest float. For deatils, see Printf width specifier to maintain precision of floating-point value

• Using "%e" allows code to distinguish small floats from each other rather than all printing "0.000000" which is the result when |x| < 0.0000005.

Example usage

#include <float.h>
#define FLT_STRING_SIZE (1+1+1+(FLT_DECIMAL_DIG-1)+1+1+ 4   +1)
                     //  - d .  dddddddd           e - dddd \0

char buf[FLT_STRING_SIZE];
sprintf(buf, "%.*e", FLT_DECIMAL_DIG-1, some_float);

Ideas:
IMO, better to use 2x buffer size for scratch pads like buf[FLT_STRING_SIZE*2].
For added robustness, use snprintf().

As a 2nd alterative consider "%.*g". It is like "%f" for values exponentially near 1.0 and like "%e" for others.

Some kotlin code:

companion object {
    fun newInstance(first: String, second: String) : SampleFragment {
        return SampleFragment().apply {
            arguments = Bundle().apply {
                putString("firstString", first)
                putString("secondString", second)
            }
        }
    }
}

And you can get arguments with this:

val first: String by lazy { arguments?.getString("firstString") ?: "default"}
val second: String by lazy { arguments?.getString("secondString") ?: "default"}

If you put in

SELECT * FROM Users WHERE RegistrationDate >= '1/20/2009' 

it will automatically convert the string '1/20/2009' into the DateTime format for a date of 1/20/2009 00:00:00. So by using >= you should get every user whose registration date is 1/20/2009 or more recent.

Edit: I put this in the comment section but I should probably link it here as well. This is an article detailing some more in depth ways of working with DateTime's in you queries: http://www.databasejournal.com/features/mssql/article.php/2209321/Working-with-SQL-Server-DateTime-Variables-Part-Three---Searching-for-Particular-Date-Values-and-Ranges.htm

I think you want preg_split:

$input = "A  B C   D";
$words = preg_split('/\s+/', $input);
var_dump($words);

You can pass function as parameter to a Go function. Here is an example of passing function as parameter to another Go function:

package main

import "fmt"

type fn func(int) 

func myfn1(i int) {
    fmt.Printf("\ni is %v", i)
}
func myfn2(i int) {
    fmt.Printf("\ni is %v", i)
}
func test(f fn, val int) {
    f(val)
}
func main() {
    test(myfn1, 123)
    test(myfn2, 321)
}

You can try this out at: https://play.golang.org/p/9mAOUWGp0k

Although SOAP and REST share similarities over the HTTP protocol, SOAP is a more rigid set of messaging patterns than REST. The rules in SOAP are relevant because we can’t achieve any degree of standardization without them. REST needs no processing as an architecture style and is inherently more versatile. In the spirit of information exchange, both SOAP and REST depend on well-established laws that everybody has decided to abide by. The choice of SOAP vs. REST is dependent on the programming language you are using the environment you are using and the specifications.

I've faced this issue and the solution was making sure that all the data from the child field are matching the parent field

for example, you want to add foreign key inside (attendance) table to the column (employeeName)

where the parent is (employees) table, (employeeName) column

all the data in attendance.employeeName must be matching employee.employeeName

If your WCF service is using .net framework 4.0 and someone has disabled TLS 1.0 on the server then you will see this exception. Due to .net 4.0 not supporting the higher versions of TLS.

is is generally preferred when comparing arbitrary objects to singletons like None because it is faster and more predictable. is always compares by object identity, whereas what == will do depends on the exact type of the operands and even on their ordering.

This recommendation is supported by PEP 8, which explicitly states that "comparisons to singletons like None should always be done with is or is not, never the equality operators."

For a string I just write "\n" to give me a new line. For example, typing console.log("First Name: Rex" + "\n" + "Last Name: Blythe"); Will type:

First Name: Rex

Last Name: Blythe

This works for me:

function isTouchDevice(){
    return true == ("ontouchstart" in window || window.DocumentTouch && document instanceof DocumentTouch);
}

Additionally for what was said, if you want integer powers of two, then 1 << x (or 1L << x) is a faster way to calculate 2^x than Math.pow(2,x) or a multiplication loop, and is guaranteed to give you an int (or long) result.

It only uses the lowest 5 (or 6) bits of x (i.e. x & 31 (or x & 63)), though, shifting between 0 and 31 (or 63) bits.

innerText is the current correct answer for this. The other answers are outdated and incorrect.

document.getElementById('ShowButton').innerText = 'Show filter';

innerHTML also works, and can be used to insert HTML.

• ws WebSocket server and client for node.js. One of the fastest libraries if not the fastest one.

• websocket-node WebSocket server and client for node.js

• websocket-driver-node WebSocket server and client protocol parser node.js - used in faye-websocket-node

• faye-websocket-node WebSocket server and client for node.js - used in faye and sockjs

• socket.io WebSocket server and client for node.js + client for browsers + (v0 has newest to oldest fallbacks, v1 of Socket.io uses engine.io) + channels - used in stack.io. Client library tries to reconnect upon disconnection.

• sockjs WebSocket server and client for node.js and others + client for browsers + newest to oldest fallbacks

• faye WebSocket server and client for node.js and others + client for browsers + fallbacks + support for other server-side languages

• deepstream.io clusterable realtime server that handles WebSockets & TCP connections and provides data-sync, pub/sub and request/response

• socketcluster WebSocket server cluster which makes use of all CPU cores on your machine. For example, if you were to use an xlarge Amazon EC2 instance with 32 cores, you would be able to handle almost 32 times the traffic on a single instance.

• primus Provides a common API for most of the libraries above for easy switching + stability improvements for all of them.

When to use:

• use the basic WebSocket servers when you want to use the native WebSocket implementations on the clientside, beware of the browser incompatabilities

• use the fallback libraries when you care about browser fallbacks

• use the full featured libraries when you care about channels

• use primus when you have no idea about what to use, are not in the mood for rewriting your application when you need to switch frameworks because of changing project requirements or need additional connection stability.

Where to test:

Firecamp is a GUI testing environment for SocketIO, WS and all major real-time technology. Debug the real-time events while you're developing it.

Different way to do multi-threading and Asynchronous in JavaScript

Before HTML5 JavaScript only allowed the execution of one thread per page.

There was some hacky way to simulate an asynchronous execution with Yield, setTimeout(), setInterval(), XMLHttpRequest or event handlers (see the end of this post for an example with yield and setTimeout()).

But with HTML5 we can now use Worker Threads to parallelize the execution of functions. Here is an example of use.

Real multi-threading

Multi-threading: JavaScript Worker Threads

HTML5 introduced Web Worker Threads (see: browsers compatibilities)
Note: IE9 and earlier versions do not support it.

These worker threads are JavaScript threads that run in background without affecting the performance of the page. For more information about Web Worker read the documentation or this tutorial.

Here is a simple example with 3 Web Worker threads that count to MAX_VALUE and show the current computed value in our page:

//As a worker normally take another JavaScript file to execute we convert the function in an URL: http://stackoverflow.com/a/16799132/2576706_x000D_
function getScriptPath(foo){ return window.URL.createObjectURL(new Blob([foo.toString().match(/^\s*function\s*\(\s*\)\s*\{(([\s\S](?!\}$))*[\s\S])/)[1]],{type:'text/javascript'})); }_x000D_
_x000D_
var MAX_VALUE = 10000;_x000D_
_x000D_
/*_x000D_
 * Here are the workers_x000D_
 */_x000D_
//Worker 1_x000D_
var worker1 = new Worker(getScriptPath(function(){_x000D_
    self.addEventListener('message', function(e) {_x000D_
        var value = 0;_x000D_
        while(value <= e.data){_x000D_
            self.postMessage(value);_x000D_
            value++;_x000D_
        }_x000D_
    }, false);_x000D_
}));_x000D_
//We add a listener to the worker to get the response and show it in the page_x000D_
worker1.addEventListener('message', function(e) {_x000D_
  document.getElementById("result1").innerHTML = e.data;_x000D_
}, false);_x000D_
_x000D_
_x000D_
//Worker 2_x000D_
var worker2 = new Worker(getScriptPath(function(){_x000D_
    self.addEventListener('message', function(e) {_x000D_
        var value = 0;_x000D_
        while(value <= e.data){_x000D_
            self.postMessage(value);_x000D_
            value++;_x000D_
        }_x000D_
    }, false);_x000D_
}));_x000D_
worker2.addEventListener('message', function(e) {_x000D_
  document.getElementById("result2").innerHTML = e.data;_x000D_
}, false);_x000D_
_x000D_
_x000D_
//Worker 3_x000D_
var worker3 = new Worker(getScriptPath(function(){_x000D_
    self.addEventListener('message', function(e) {_x000D_
        var value = 0;_x000D_
        while(value <= e.data){_x000D_
            self.postMessage(value);_x000D_
            value++;_x000D_
        }_x000D_
    }, false);_x000D_
}));_x000D_
worker3.addEventListener('message', function(e) {_x000D_
    document.getElementById("result3").innerHTML = e.data;_x000D_
}, false);_x000D_
_x000D_
_x000D_
// Start and send data to our worker._x000D_
worker1.postMessage(MAX_VALUE); _x000D_
worker2.postMessage(MAX_VALUE); _x000D_
worker3.postMessage(MAX_VALUE);

<div id="result1"></div>_x000D_
<div id="result2"></div>_x000D_
<div id="result3"></div>

We can see that the three threads are executed in concurrency and print their current value in the page. They don't freeze the page because they are executed in the background with separated threads.

Multi-threading: with multiple iframes

Another way to achieve this is to use multiple iframes, each one will execute a thread. We can give the iframe some parameters by the URL and the iframe can communicate with his parent in order to get the result and print it back (the iframe must be in the same domain).

This example doesn't work in all browsers! iframes usually run in the same thread/process as the main page (but Firefox and Chromium seem to handle it differently).

Since the code snippet does not support multiple HTML files, I will just provide the different codes here:

index.html:

//The 3 iframes containing the code (take the thread id in param)
<iframe id="threadFrame1" src="thread.html?id=1"></iframe>
<iframe id="threadFrame2" src="thread.html?id=2"></iframe>
<iframe id="threadFrame3" src="thread.html?id=3"></iframe>

//Divs that shows the result
<div id="result1"></div>
<div id="result2"></div>
<div id="result3"></div>


<script>
    //This function is called by each iframe
    function threadResult(threadId, result) {
        document.getElementById("result" + threadId).innerHTML = result;
    }
</script>

thread.html:

//Get the parameters in the URL: http://stackoverflow.com/a/1099670/2576706
function getQueryParams(paramName) {
    var qs = document.location.search.split('+').join(' ');
    var params = {}, tokens, re = /[?&]?([^=]+)=([^&]*)/g;
    while (tokens = re.exec(qs)) {
        params[decodeURIComponent(tokens[1])] = decodeURIComponent(tokens[2]);
    }
    return params[paramName];
}

//The thread code (get the id from the URL, we can pass other parameters as needed)
var MAX_VALUE = 100000;
(function thread() {
    var threadId = getQueryParams('id');
    for(var i=0; i<MAX_VALUE; i++){
        parent.threadResult(threadId, i);
    }
})();

Simulate multi-threading

Single-thread: emulate JavaScript concurrency with setTimeout()

The 'naive' way would be to execute the function setTimeout() one after the other like this:

setTimeout(function(){ /* Some tasks */ }, 0);
setTimeout(function(){ /* Some tasks */ }, 0);
[...]

But this method does not work because each task will be executed one after the other.

We can simulate asynchronous execution by calling the function recursively like this:

var MAX_VALUE = 10000;_x000D_
_x000D_
function thread1(value, maxValue){_x000D_
    var me = this;_x000D_
    document.getElementById("result1").innerHTML = value;_x000D_
    value++;_x000D_
  _x000D_
    //Continue execution_x000D_
    if(value<=maxValue)_x000D_
        setTimeout(function () { me.thread1(value, maxValue); }, 0);_x000D_
}_x000D_
_x000D_
function thread2(value, maxValue){_x000D_
    var me = this;_x000D_
    document.getElementById("result2").innerHTML = value;_x000D_
    value++;_x000D_
 _x000D_
    if(value<=maxValue)_x000D_
        setTimeout(function () { me.thread2(value, maxValue); }, 0);_x000D_
}_x000D_
_x000D_
function thread3(value, maxValue){_x000D_
    var me = this;_x000D_
    document.getElementById("result3").innerHTML = value;_x000D_
    value++;_x000D_
 _x000D_
    if(value<=maxValue)_x000D_
        setTimeout(function () { me.thread3(value, maxValue); }, 0);_x000D_
}_x000D_
_x000D_
thread1(0, MAX_VALUE);_x000D_
thread2(0, MAX_VALUE);_x000D_
thread3(0, MAX_VALUE);

<div id="result1"></div>_x000D_
<div id="result2"></div>_x000D_
<div id="result3"></div>

As you can see this second method is very slow and freezes the browser because it uses the main thread to execute the functions.

Single-thread: emulate JavaScript concurrency with yield

Yield is a new feature in ECMAScript 6, it only works on the oldest version of Firefox and Chrome (in Chrome you need to enable Experimental JavaScript appearing in chrome://flags/#enable-javascript-harmony).

The yield keyword causes generator function execution to pause and the value of the expression following the yield keyword is returned to the generator's caller. It can be thought of as a generator-based version of the return keyword.

A generator allows you to suspend execution of a function and resume it later. A generator can be used to schedule your functions with a technique called trampolining.

Here is the example:

var MAX_VALUE = 10000;_x000D_
_x000D_
Scheduler = {_x000D_
 _tasks: [],_x000D_
 add: function(func){_x000D_
  this._tasks.push(func);_x000D_
 }, _x000D_
 start: function(){_x000D_
  var tasks = this._tasks;_x000D_
  var length = tasks.length;_x000D_
  while(length>0){_x000D_
   for(var i=0; i<length; i++){_x000D_
    var res = tasks[i].next();_x000D_
    if(res.done){_x000D_
     tasks.splice(i, 1);_x000D_
     length--;_x000D_
     i--;_x000D_
    }_x000D_
   }_x000D_
  }_x000D_
 } _x000D_
}_x000D_
_x000D_
_x000D_
function* updateUI(threadID, maxValue) {_x000D_
  var value = 0;_x000D_
  while(value<=maxValue){_x000D_
 yield document.getElementById("result" + threadID).innerHTML = value;_x000D_
 value++;_x000D_
  }_x000D_
}_x000D_
_x000D_
Scheduler.add(updateUI(1, MAX_VALUE));_x000D_
Scheduler.add(updateUI(2, MAX_VALUE));_x000D_
Scheduler.add(updateUI(3, MAX_VALUE));_x000D_
_x000D_
Scheduler.start()

<div id="result1"></div>_x000D_
<div id="result2"></div>_x000D_
<div id="result3"></div>

If you recently changed the password associated with the service account:

1. Start SQL Server Configuration Manager.
2. Select SQL Server Services in the left pane.
3. Right click the service you are trying to start in the right pane and click Properties.
4. Enter the new Password and Confirm password.

I would always recommend going to the authoritative source when trying to understand the meaning and purpose of HTTP headers.

The "Host" header field in a request provides the host and port
information from the target URI, enabling the origin server to
distinguish among resources while servicing requests for multiple
host names on a single IP address.

Such kind of error normally happens when you try using functions like php_info() wrongly.

<?php 
     php_info(); // 500 error
     phpinfo(); // Works correctly
?>

A close look at your code will be better.

So the correct answer is: YES, there is a better way.

Right click on the tab and select "Duplicate", then close the original tab if you wish.

Alerting is re-enabled in the duplicate.

The duplicate tab seems to recreate the running state of the original tab so you can just continue where you were.

In MongoDB Stitch functions it can be done using BSON like below:

Use the ObjectId helper in the BSON utility package for this purpose like in the follwing example:

var id = "5bb9e9f84186b222c8901149";  
BSON.ObjectId(id);

bundle exec is a Bundler command to execute a script in the context of the current bundle (the one from your directory's Gemfile). rake db:migrate is the script where db is the namespace and migrate is the task name defined.

So bundle exec rake db:migrate executes the rake script with the command db:migrate in the context of the current bundle.

As to the "why?" I'll quote from the bundler page:

In some cases, running executables without bundle exec may work, if the executable happens to be installed in your system and does not pull in any gems that conflict with your bundle.

However, this is unreliable and is the source of considerable pain. Even if it looks like it works, it may not work in the future or on another machine.

Take an input float as left. Then take the button and float it right. You can clearfix class when you take more than one to distance.

<input style="width:65%;float:left"class="btn btn-primary" type="text" name="name"> 
<div style="width:8%;float:left">&nbsp;</div>
<button class="btn btn-default" type="button">Go!</button>
<div class="clearfix" style="margin-bottom:10px"> </div>

Update: This should probably be the accepted answer since maxElement appeared in Swift.

Use the almighty reduce:

let nums = [1, 6, 3, 9, 4, 6];
let numMax = nums.reduce(Int.min, { max($0, $1) })

Similarly:

let numMin = nums.reduce(Int.max, { min($0, $1) })

reduce takes a first value that is the initial value for an internal accumulator variable, then applies the passed function (here, it's anonymous) to the accumulator and each element of the array successively, and stores the new value in the accumulator. The last accumulator value is then returned.

Use this:

SELECT *
FROM Sales.SalesOrderHeader 
ORDER BY OrderDate
OFFSET (@Skip) ROWS FETCH NEXT (@Take) ROWS ONLY
