Programs & Examples On #Django reversion

I ended in this stackoverflow question after looking for help to solve my problem but found no solution to it :(

So I had to improvise... after some time I managed to reach the regex I needed:

As you can see, I needed up to one folder ahead of "grp-bps" folder, without including last dash. And it was required to have at least one folder after "grp-bps" folder.

Edit

Text version for copy-paste (change 'grp-bps' for your text):

.*\/grp-bps\/[^\/]+

You want to have a look at FileField and FieldFile in the Django docs, and especially FieldFile.save().

Basically, a field declared as a FileField, when accessed, gives you an instance of class FieldFile, which gives you several methods to interact with the underlying file. So, what you need to do is:

self.license_file.save(new_name, new_contents)

where new_name is the filename you wish assigned and new_contents is the content of the file. Note that new_contents must be an instance of either django.core.files.File or django.core.files.base.ContentFile (see given links to manual for the details).

The two choices boil down to:

from django.core.files.base import ContentFile, File

# Using File
with open('/path/to/file') as f:
    self.license_file.save(new_name, File(f))

# Using ContentFile
self.license_file.save(new_name, ContentFile('A string with the file content'))

The other answers here are very much correct, and valuable. But sometimes you just want simple: to get a plain old parsed value at directive instantiation, without needing updates, and without messing with isolate scope. For instance, it can be handy to provide a declarative payload into your directive as an array or hash-object in the form:

my-directive-name="['string1', 'string2']"

In that case, you can cut to the chase and just use a nice basic angular.$eval(attr.attrName).

element.val("value = "+angular.$eval(attr.value));

Working Fiddle.

Here is a crude timing test to compare the two:

import java.util.Date;

public class EnumCompareSpeedTest {

    static enum TestEnum {ONE, TWO, THREE }

    public static void main(String [] args) {

        Date before = new Date();
        int c = 0;

        for(int y=0;y<5;++y) {
            for(int x=0;x<Integer.MAX_VALUE;++x) {
                if(TestEnum.ONE.equals(TestEnum.TWO)) {++c;}
                if(TestEnum.ONE == TestEnum.TWO){++c;}              
            }
        }

        System.out.println(new Date().getTime() - before.getTime());
    }   

}

Comment out the IFs one at a time. Here are the two compares from above in disassembled byte-code:

 21  getstatic EnumCompareSpeedTest$TestEnum.ONE : EnumCompareSpeedTest.TestEnum [19]
 24  getstatic EnumCompareSpeedTest$TestEnum.TWO : EnumCompareSpeedTest.TestEnum [25]
 27  invokevirtual EnumCompareSpeedTest$TestEnum.equals(java.lang.Object) : boolean [28]
 30  ifeq 36

 36  getstatic EnumCompareSpeedTest$TestEnum.ONE : EnumCompareSpeedTest.TestEnum [19]
 39  getstatic EnumCompareSpeedTest$TestEnum.TWO : EnumCompareSpeedTest.TestEnum [25]
 42  if_acmpne 48

The first (equals) performs a virtual call and tests the return boolean from the stack. The second (==) compares the object addresses directly from the stack. In the first case there is more activity.

I ran this test several times with both IFs one at a time. The "==" is ever so slightly faster.

You can add your own custom error handler, which can provide extra debug information. Furthermore, you can set it up to send you the information via email.

function ERR_HANDLER($errno, $errstr, $errfile, $errline){
    $msg = "<b>Something bad happened.</b> [$errno] $errstr <br><br>
    <b>File:</b> $errfile <br>
    <b>Line:</b> $errline <br>
    <pre>".json_encode(debug_backtrace(), JSON_PRETTY_PRINT)."</pre> <br>";

    echo $msg;

    return false;
}

function EXC_HANDLER($exception){
    ERR_HANDLER(0, $exception->getMessage(), $exception->getFile(), $exception->getLine());
}

function shutDownFunction() {
    $error = error_get_last();
    if ($error["type"] == 1) {
        ERR_HANDLER($error["type"], $error["message"], $error["file"], $error["line"]);
    }
}

set_error_handler ("ERR_HANDLER", E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED);
register_shutdown_function("shutdownFunction");
set_exception_handler("EXC_HANDLER");

The solution was to call...

$scope.$apply();

...in my jQuery event callback.

In new version of Laravel you can use "Service Injection".

https://laravel.com/docs/5.8/blade#service-injection

/resources/views/main.blade.php

@inject('project', 'App\Project')

<h1>{{ $project->get_title() }}</h1>

Also you can add #include<vector> in the header. When two of the above solutions don't work.

Short Answer: No. Until recently(about 1 month ago), you could do that but with the latest updates, it is not possible. (see Update to Android SDK Tools 23.0.5 and avd doesn't start).

I was doing something similar: Doing development in a virtual machine and hence couldn't use the Hardware acceleration features as they are available only in the host machine. I was using Intel x86 images with Use Host GPU option; as they were much faster than the ARM version even without hardware acceleration. But then, after this update, my emulator AVDs which were working earlier are no longer starting with the same exact error message. Also, both genymotion and Xamarin Android emulators can't be used as they also need hardware acceleration(they are actually VMs which use Hardware acceleration for speed, and hence can't be run inside another VM).

I have found this solution but haven't tried it yet. The basic idea is that to still develop inside a VM; but for testing connect to an Emulator running on the host machine(and this Emulator VM can now use the hardware acceleration feature).

to add to John's answer:

what you want to pass to the shuffle function is a deck of cards from the class deckOfCards that you've declared in main; however, the deck of cards or vector<Card> deck that you've declared in your class is private, so not accessible from outside the class. this means you'd want a getter function, something like this:

class deckOfCards
{
    private:
        vector<Card> deck;

    public:
        deckOfCards();
        static int count;
        static int next;
        void shuffle(vector<Card>& deck);
        Card dealCard();
        bool moreCards();
        vector<Card>& getDeck() {   //GETTER
            return deck;
        }
};

this will in turn allow you to call your shuffle function from main like this:

deckOfCards cardDeck; // create DeckOfCards object
cardDeck.shuffle(cardDeck.getDeck()); // shuffle the cards in the deck

however, you have more problems, specifically when calling cout. first, you're calling the dealCard function wrongly; as dealCard is a memeber function of a class, you should be calling it like this cardDeck.dealCard(); instead of this dealCard(cardDeck);.

now, we come to your second problem - print to standard output. you're trying to print your deal card, which is an object of type Card by using the following instruction:

cout << cardDeck.dealCard();// deal the cards in the deck

yet, the cout doesn't know how to print it, as it's not a standard type. this means you should overload your << operator to print whatever you want it to print when calling with a Card type.

The correct syntax is

set def off;
insert into tablename values( 'J&J');

Another solution is to use the config file without any settings. The first time you might have to include your mysql root login/password so it can install all its stuff but then remove it.

$cfg['Servers'][$i]['auth_type'] = 'cookie';

$cfg['Servers'][$i]['host'] = 'localhost';

$cfg['Servers'][$i]['connect_type'] = 'tcp';

$cfg['Servers'][$i]['compress'] = false;

$cfg['Servers'][$i]['extension'] = 'mysql';

Leaving it like that without any apache/lighhtpd aliases will just present to you a log in screen.

You can log in with root but it is advised to create other users and only allow root for local access. Also remember to use string passwords, even if short but with a capital, and number of special character. for example !34sy2rmbr! aka "easy 2 remember"

-EDIT: A good password now a days is actually something like words that make no grammatical sense but you can remember because they funny. Or use keepass to generate strong randoms an have easy access to them

Here's a useful little function, which makes using/creating iOS folders a little easier.

You pass it the name of a subfolder, it'll return the full path back to you, and make sure the directory exists.

(Personally, I stick this static function in my AppDelete class, but perhaps this isn't the smartest place to put it.)

Here's how you would call it, to get the "full path" of a MySavedImages subdirectory:

NSString* fullPath = [AppDelegate getFullPath:@"MySavedImages"];

And here's the full function:

+(NSString*)getFullPath:(NSString*)folderName
{
    //  Check whether a subdirectory exists in our sandboxed Documents directory.
    //  Returns the full path of the directory.
    //
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    if (paths.count < 1)
        return nil;

    NSString *rootFolder = [paths firstObject];
    NSString* fullFolderPath = [rootFolder stringByAppendingPathComponent:folderName];

    BOOL isDirectory;
    NSFileManager* manager = [NSFileManager defaultManager];

    if (![manager fileExistsAtPath:fullFolderPath isDirectory:&isDirectory] || !isDirectory) {
        NSError *error = nil;
        NSDictionary *attr = [NSDictionary dictionaryWithObject:NSFileProtectionComplete
                                                         forKey:NSFileProtectionKey];
        [manager createDirectoryAtPath:fullFolderPath
           withIntermediateDirectories:YES
                            attributes:attr
                                 error:&error];
        if (error) {
            NSLog(@"Error creating directory path: %@", [error localizedDescription]);
            return nil;
        }
    }
    return fullFolderPath;
}

Using this little function, it's easy to create a directory in your app's Documents directory (if it doesn't already exist), and to write a file into it.

Here's how I would create the directory, and write the contents of one of my image files into it:

//  Let's create a "MySavedImages" subdirectory (if it doesn't already exist)
NSString* fullPath = [AppDelegate getFullPath:@"MySavedImages"];

//  As an example, let's load the data in one of my images files
NSString* imageFilename = @"icnCross.png";

UIImage* image = [UIImage imageNamed:imageFilename];
NSData *imageData = UIImagePNGRepresentation(image);

//  Obtain the full path+filename where we can write this .png to, in our new MySavedImages directory
NSString* imageFilePathname = [fullPath stringByAppendingPathComponent:imageFilename];

//  Write the data
[imageData writeToFile:imageFilePathname atomically:YES];

Hope this helps !

skip = OFFSET
$products = $art->products->skip(0)->take(10)->get(); //get first 10 rows
$products = $art->products->skip(10)->take(10)->get(); //get next 10 rows

From laravel doc 5.2 https://laravel.com/docs/5.2/queries#ordering-grouping-limit-and-offset

skip / take

To limit the number of results returned from the query, or to skip a given number of results in the query (OFFSET), you may use the skip and take methods:

$users = DB::table('users')->skip(10)->take(5)->get();

In laravel 5.3 you can write (https://laravel.com/docs/5.3/queries#ordering-grouping-limit-and-offset)

$products = $art->products->offset(0)->limit(10)->get(); 

The problem sometimes occurs when there are errors in the project.

For instance, if your project is configured with a target of 3.2 but the 3.2 libraries are not available, you will not be able to change the version to 4.0!

The usual (perhaps brutal) solution I use is to create a new project with the correct target and copy src, res and manifest into the new project.

Update:

This seems to work:

1. Change the selected through the build properties as normal
2. Manually edit project.properties AND default.properties to make sure they both reflect the desired target.
3. Close the project and re-open it

I always run Android Tools | Fix Project Properties after making any changes to the build target.

Very simple way

On parent DIV:

height: 100%;

This work for me every time

If you really need to do this, use reverse proxy.

For example, with nginx as reverse proxy

server {
  listen       api.mydomain.com:80;
  server_name  api.mydomain.com;
  location / {
    proxy_pass http://127.0.0.1:8000;
  }
}

You can see a complete example using java 8, recursion and streams -> Dijkstra algorithm with java

import random
random.shuffle(array)

<?php if(!class_exists('PDO2')) {
    class PDO2 {
        private static $_instance;
        public static function getInstance() {
            if (!isset(self::$_instance)) {
                try {
                    self::$_instance = new PDO(
                        'mysql:host=***;dbname=***',
                        '***',
                        '***',
                        array(
                            PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8mb4 COLLATE utf8mb4_general_ci",
                            PDO::ATTR_ERRMODE            => PDO::ERRMODE_EXCEPTION
                        )
                    );
                } catch (PDOException $e) {
                    throw new PDOException($e->getMessage(), (int) $e->getCode());
                }
            }
            return self::$_instance;
        }
        public static function closeInstance() {
            return self::$_instance = null;
        }
    }
}
$req = PDO2::getInstance()->prepare('SELECT * FROM table');
$req->execute();
$count = $req->rowCount();
$results = $req->fetchAll(PDO::FETCH_ASSOC);
$req->closeCursor();
// Do other requests maybe
// And close connection
PDO2::closeInstance();
// print output

Full example, with custom class PDO2.

Your also have to register the receiver in onCreate(), like this:

IntentFilter filter = new IntentFilter();
filter.addAction("csinald.meg");
registerReceiver(receiver, filter);

You could just try the scandir(Path) function. it is fast and easy to implement

Syntax:

$files = scandir("somePath");

This Function returns a list of file into an Array.

to view the result, you can try

var_dump($files);

Or

foreach($files as $file)
{ 
echo $file."< br>";
} 

Because the Method2 is static, all you have to do is call like this:

public class AllMethods
{
    public static void Method2()
    {
        // code here
    }
}

class Caller
{
    public static void Main(string[] args)
    {
        AllMethods.Method2();
    }
}

If they are in different namespaces you will also need to add the namespace of AllMethods to caller.cs in a using statement.

If you wanted to call an instance method (non-static), you'd need an instance of the class to call the method on. For example:

public class MyClass
{
    public void InstanceMethod() 
    { 
        // ...
    }
}

public static void Main(string[] args)
{
    var instance = new MyClass();
    instance.InstanceMethod();
}

Update

As of C# 6, you can now also achieve this with using static directive to call static methods somewhat more gracefully, for example:

// AllMethods.cs
namespace Some.Namespace
{
    public class AllMethods
    {
        public static void Method2()
        {
            // code here
        }
    }
}

// Caller.cs
using static Some.Namespace.AllMethods;

namespace Other.Namespace
{
    class Caller
    {
        public static void Main(string[] args)
        {
            Method2(); // No need to mention AllMethods here
        }
    }
}

I've generally used xml drawables to create shadow/elevation on a pre-lollipop widget. Here, for example, is an xml drawable that can be used on pre-lollipop devices to simulate the floating action button's elevation.

In place of ?attr/colorPrimary you can choose any color. Here's a screenshot of the result:

The -Contains operator doesn't do substring comparisons and the match must be on a complete string and is used to search collections.

From the documentation you linked to:

-Contains Description: Containment operator. Tells whether a collection of reference values includes a single test value.

In the example you provided you're working with a collection containing just one string item.

If you read the documentation you linked to you'll see an example that demonstrates this behaviour:

Examples:

PS C:\> "abc", "def" -Contains "def"
True

PS C:\> "Windows", "PowerShell" -Contains "Shell"
False  #Not an exact match

I think what you want is the -Match operator:

"12-18" -Match "-"

Which returns True.

Important: As pointed out in the comments and in the linked documentation, it should be noted that the -Match operator uses regular expressions to perform text matching.

Simplest of all would be.

• Create xml layout file for dialog . Add whatever view you want like EditText , ListView , Spinner etc.

  Inflate this view and set this to AlertDialog

Lets start with Layout file first.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical">


    <EditText
        android:id="@+id/etComments"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="top"
        android:hint="Enter comments(Optional)"
        android:inputType="textMultiLine"
        android:lines="8"
        android:maxLines="3"
        android:minLines="6"
        android:scrollbars="vertical" />

</LinearLayout>

final View view = layoutInflater.inflate(R.layout.xml_file_created_above, null);
AlertDialog alertDialog = new AlertDialog.Builder(ct).create();
alertDialog.setTitle("Your Title Here");
alertDialog.setIcon("Icon id here");
alertDialog.setCancelable(false);
Constant.alertDialog.setMessage("Your Message Here");


final EditText etComments = (EditText) view.findViewById(R.id.etComments);

alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK", new OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {

    }
});


alertDialog.setButton(AlertDialog.BUTTON_NEGATIVE, "Cancel", new OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
        alertDialog.dismiss()
    }
});


alertDialog.setView(view);
alertDialog.show();

public enum Direction {
    NORTH, EAST, SOUTH, WEST;

    public Direction getOppositeDirection(){
        return Direction.values()[(this.ordinal() + 2) % 4];
    }
}

Enums have a static values method that returns an array containing all of the values of the enum in the order they are declared. source

since NORTH gets 1, EAST gets 2, SOUTH gets 3, WEST gets 4; you can create a simple equation to get the opposite one:

(value + 2) % 4

I know this is an old question, but the following should work if you don't need the month name at the DB level:

  SELECT EXTRACT(YEAR_MONTH FROM summaryDateTime) summary_year_month 
    FROM trading_summary  
GROUP BY summary_year_month;

See EXTRACT function docs

You will probably find this to be better performing.. and if you are building a JSON object in the application layer, you can do the formatting/ordering as you run through the results.

N.B. I wasn't aware you could add DESC to a GROUP BY clause in MySQL, perhaps you are missing an ORDER BY clause:

  SELECT EXTRACT(YEAR_MONTH FROM summaryDateTime) summary_year_month 
    FROM trading_summary  
GROUP BY summary_year_month
ORDER BY summary_year_month DESC;

Noticing that user 42-'s perfect approach {
* "do while" = "repeat until not"
* The code equivalence:

do while (condition) # in other language
..statements..
endo

repeat{ # in R
  ..statements..
  if(! condition){ break } # Negation is crucial here!
}

} did not receive enough attention from the others, I'll emphasize and bring forward his approach via a concrete example. If one does not negate the condition in do-while (via ! or by taking negation), then distorted situations (1. value persistence 2. infinite loop) exist depending on the course of the code.

In Gauss:

proc(0)=printvalues(y);
DO WHILE y < 5;    
y+1;
 y=y+1;
ENDO;
ENDP;
printvalues(0); @ run selected code via F4 to get the following @
       1.0000000 
       2.0000000 
       3.0000000 
       4.0000000 
       5.0000000 

In R:

printvalues <- function(y) {
repeat {
 y=y+1;
print(y)
if (! (y < 5) ) {break}   # Negation is crucial here!
}
}
printvalues(0)
# [1] 1
# [1] 2
# [1] 3
# [1] 4
# [1] 5

I still insist that without the negation of the condition in do-while, Salcedo's answer is wrong. One can check this via removing negation symbol in the above code.

You can use the with template tag.

{% with name="World" %}     
<html>
<div>Hello {{name}}!</div>
</html>
{% endwith %}

str = str.replace(',', '.')

should do the trick.

Something like this might be the easiest way.

then() function is related to "Javascript promises" that are used in some libraries or frameworks like jQuery or AngularJS.

A promise is a pattern for handling asynchronous operations. The promise allows you to call a method called "then" that lets you specify the function(s) to use as the callbacks.

For more information see: http://wildermuth.com/2013/8/3/JavaScript_Promises

And for Angular promises: http://liamkaufman.com/blog/2013/09/09/using-angularjs-promises/

If you want only corner should curve not whole end, then use below code.

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

    <corners android:radius="10dp" />

    <padding
        android:bottom="3dp"
        android:left="0dp"
        android:right="0dp"
        android:top="3dp" />

    <gradient
        android:angle="90"
        android:endColor="@color/White"
        android:startColor="@color/White" />

    <stroke
        android:width="1dp"
        android:color="@color/Gray" />

</shape>

It will only curve the four angle of EditText.

var http = require('http');
var url  = require('url');
var fs   = require('fs');

var neededstats = [];

http.createServer(function(req, res) {
    if (req.url == '/index.html' || req.url == '/') {
        fs.readFile('./index.html', function(err, data) {
            res.end(data);
        });
    } else {
        var p = __dirname + '/' + req.params.filepath;
        fs.stat(p, function(err, stats) {
            if (err) {
                throw err;
            }
            neededstats.push(stats.mtime);
            neededstats.push(stats.size);
            res.send(neededstats);
        });
    }
}).listen(8080, '0.0.0.0');
console.log('Server running.');

I have not tested your code but other things works

If you want to get the path info from request url

 var url_parts = url.parse(req.url);
 console.log(url_parts);
 console.log(url_parts.pathname);

1.If you are getting the URL parameters still not able to read the file just correct your file path in my example. If you place index.html in same directory as server code it would work...

2.if you have big folder structure that you want to host using node then I would advise you to use some framework like expressjs

If you want raw solution to file path

var http = require("http");
var url = require("url");

function start() {
function onRequest(request, response) {
    var pathname = url.parse(request.url).pathname;
    console.log("Request for " + pathname + " received.");
    response.writeHead(200, {"Content-Type": "text/plain"});
    response.write("Hello World");
    response.end();
}

http.createServer(onRequest).listen(8888);
console.log("Server has started.");
}

exports.start = start;

There is an old plugin called HEX Editor here.

According to this question on Super User it does not work on newer versions of Notepad++ and might have some stability issues, but it still could be useful depending on your needs.

For me, the main difference is that a script is interpreted, while a program is executed (i.e. the source is first compiled, and the result of that compilation is expected).

Wikipedia seems to agree with me on this :

Script :

"Scripts" are distinct from the core code of the application, which is usually written in a different language, and are often created or at least modified by the end-user.
Scripts are often interpreted from source code or bytecode, whereas the applications they control are traditionally compiled to native machine code.

Program :

The program has an executable form that the computer can use directly to execute the instructions.
The same program in its human-readable source code form, from which executable programs are derived (e.g., compiled)

My situation was that I have a bare repo that the team pushes to, and a clone of that sitting right next to it. This set of lines in a Makefile work correctly for me:

git reset --hard
git remote update --prune
git pull --rebase --all
git cherry-pick -n remotes/origin/$(BRANCH)

By keeping the master of the bare repo up to date, we are able to cherry-pick a proposed change published to the bare repo. We also have a (more complicated) way to cherry-pick multiple braches for consolidated review and testing.

If "knows nothing" means "can't be used as a remote", then this doesn't help, but this SO question came up as I was googling around to come up with this workflow so I thought I'd contribute back.

If you restructured your date format into YYYY/MM/DD then you can use this simple string ordering to achieve the formating you need.

Alternatively, using the SUBSTR(store_name,start,length) command you should be able to restructure the sorting term into the above format

perhaps using the following

SELECT     *
FROM         vw_view
ORDER BY SUBSTR(EventDate,6,4) + SUBSTR(EventDate, 0, 5) DESC

TCP establishes a connection before the actual data transmission takes place, UDP does not. In this way, UDP can provide faster delivery. Applications like DNS, time server access, therefore, use UDP.

Unlike UDP, TCP uses congestion control. It responses to the network load. Unlike UDP, it slows down when network congestion is imminent. So, applications like multimedia preferring constant throughput might go for UDP.

Besides, UDP is unreliable, it doesn't react on packet losses. So loss sensitive applications like multimedia transmission prefer UDP. However, TCP is a reliable protocol, so, applications that require reliability such as web transfer, email, file download prefer TCP.

Besides, in today's internet UDP is not as welcoming as TCP due to middle boxes. Some applications like skype fall down to TCP when UDP connection is assumed to be blocked.

You could use the JS confirm function.

<form onSubmit="if(!confirm('Is the form filled out correctly?')){return false;}">
  <input type="submit" />

In short, yes. I assume you're looking to parse English: for that you can use the Link Parser from Carnegie Mellon.

It is important to remember that there are many theories of syntax, that can give completely different-looking phrase structure trees; further, the trees are different for each language, and tools may not exist for those languages.

As a note for the future: if you need a sentence parsed out and tag it as linguistics (and syntax or whatnot, if that's available), someone can probably parse it out for you and guide you through it.

In my view page:

<p:dataTable  ...>
<p:column>
<p:commandLink actionListener="#{inquirySOController.viewDetail}" 
               process="@this" update=":mainform:dialog_content"
           oncomplete="dlg2.show()">
    <h:graphicImage library="images" name="view.png"/>
    <f:param name="trxNo" value="#{item.map['trxNo']}"/>
</p:commandLink>
</p:column>
</p:dataTable>

backing bean

 public void viewDetail(ActionEvent e) {

    String trxNo = getFacesContext().getRequestParameterMap().get("trxNo");

    for (DTO item : list) {
        if (item.get("trxNo").toString().equals(trxNo)) {
            System.out.println(trxNo);
            setSelectedItem(item);
            break;
        }
    }
}

Exact same thing, just omit the -c option. Apache's docs on it here.

htpasswd /etc/apache2/.htpasswd newuser

Also, htpasswd typically isn't run as root. It's typically owned by either the web server, or the owner of the files being served. If you're using root to edit it instead of logging in as one of those users, that's acceptable (I suppose), but you'll want to be careful to make sure you don't accidentally create a file as root (and thus have root own it and no one else be able to edit it).

When you create an object of a class using new keyword in some other class, you are actually doing tight coupling (bad practice) instead you should use loose coupling which is a good practice

---A.java---

package interface_package.loose_coupling;

public class A {

void display(InterfaceClass obji)
{
    obji.display();
    System.out.println(obji.getVar());
}
}

---B.java---

package interface_package.loose_coupling;

public class B implements InterfaceClass{

private String var="variable Interface";

public String getVar() {
    return var;
}

public void setVar(String var) {
    this.var = var;
}

@Override
public void display() {
    // TODO Auto-generated method stub
    System.out.println("Display Method Called");
}
}

---InterfaceClass---

package interface_package.loose_coupling;

public interface InterfaceClass {

void display();
String getVar();
}

---MainClass---

package interface_package.loose_coupling;

public class MainClass {

public static void main(String[] args) {
    // TODO Auto-generated method stub

    A obja=new A();
    B objb=new B();
    obja.display(objb);     //Calling display of A class with object of B class 

}
}

Explanation:

In above example, we have two classes A and B

Class B implements Interface i.e. InterfaceClass.

InterfaceClass defines a Contract for B class as InterfaceClass have abstract methods of B class that can be access by any other class for example A.

In Class A we have display method which can except object of class which implements InterfaceClass (in our case it is B class). And on that object method of class A is calling display() and getVar() of class B

In MainClass we have created object of Class A and B. And calling display method of A by passing object of B class i.e. objb. Display method of A will be called with object of B class.

Now talking about loose coupling. Suppose in future you have to change the name of Class B to ABC then you do not have to change its name in display method of class B, just make the object of new (ABC class) and pass it to the display method in MailClass. You do not have to change anything in Class A

According to MSDN the method Guid.ToString(string format) returns a string representation of the value of this Guid instance, according to the provided format specifier.

Examples:

• guidVal.ToString() or guidVal.ToString("D") returns 32 hex digits separated by hyphens: 00000000-0000-0000-0000-000000000000
• guidVal.ToString("N") returns 32 hex digits:00000000000000000000000000000000
• guidVal.ToString("B") returns 32 hex digits separated by hyphens, enclosed in braces:{00000000-0000-0000-0000-000000000000}
• guidVal.ToString("P") returns 32 hex digits separated by hyphens, enclosed in parentheses: (00000000-0000-0000-0000-000000000000)

Whether you're running within the context of ASP.NET or not, you should be able to use HostingEnvironment.ApplicationPhysicalPath

proxy = urllib2.ProxyHandler({'http': '127.0.0.1'})
opener = urllib2.build_opener(proxy)
urllib2.install_opener(opener)
urllib2.urlopen('http://www.google.com')

First of all we will get source and destination points between which we have to draw route. Then we will pass these attribute to below function.

 public String makeURL (double sourcelat, double sourcelog, double destlat, double destlog ){
        StringBuilder urlString = new StringBuilder();
        urlString.append("http://maps.googleapis.com/maps/api/directions/json");
        urlString.append("?origin=");// from
        urlString.append(Double.toString(sourcelat));
        urlString.append(",");
        urlString.append(Double.toString( sourcelog));
        urlString.append("&destination=");// to
        urlString.append(Double.toString( destlat));
        urlString.append(",");
        urlString.append(Double.toString( destlog));
        urlString.append("&sensor=false&mode=driving&alternatives=true");
        urlString.append("&key=YOUR_API_KEY");
        return urlString.toString();
 }

This function will make the url that we will send to get Direction API response. Then we will parse that response . The parser class is

public class JSONParser {

    static InputStream is = null;
    static JSONObject jObj = null;
    static String json = "";
    // constructor
    public JSONParser() {
    }
    public String getJSONFromUrl(String url) {

        // Making HTTP request
        try {
            // defaultHttpClient
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);

            HttpResponse httpResponse = httpClient.execute(httpPost);
            HttpEntity httpEntity = httpResponse.getEntity();
            is = httpEntity.getContent();           

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }

            json = sb.toString();
            is.close();
        } catch (Exception e) {
            Log.e("Buffer Error", "Error converting result " + e.toString());
        }
        return json;

    }
}

This parser will return us string. We will call it like that.

JSONParser jParser = new JSONParser();
String json = jParser.getJSONFromUrl(url);

Now we will send this string to our drawpath function. The drawpath function is

public void drawPath(String  result) {

    try {
            //Tranform the string into a json object
           final JSONObject json = new JSONObject(result);
           JSONArray routeArray = json.getJSONArray("routes");
           JSONObject routes = routeArray.getJSONObject(0);
           JSONObject overviewPolylines = routes.getJSONObject("overview_polyline");
           String encodedString = overviewPolylines.getString("points");
           List<LatLng> list = decodePoly(encodedString);
           Polyline line = mMap.addPolyline(new PolylineOptions()
                                    .addAll(list)
                                    .width(12)
                                    .color(Color.parseColor("#05b1fb"))//Google maps blue color
                                    .geodesic(true)
                    );
           /*
           for(int z = 0; z<list.size()-1;z++){
                LatLng src= list.get(z);
                LatLng dest= list.get(z+1);
                Polyline line = mMap.addPolyline(new PolylineOptions()
                .add(new LatLng(src.latitude, src.longitude), new LatLng(dest.latitude,   dest.longitude))
                .width(2)
                .color(Color.BLUE).geodesic(true));
            }
           */
    } 
    catch (JSONException e) {

    }
} 

Above code will draw the path on mMap. The code of decodePoly is

private List<LatLng> decodePoly(String encoded) {

    List<LatLng> poly = new ArrayList<LatLng>();
    int index = 0, len = encoded.length();
    int lat = 0, lng = 0;

    while (index < len) {
        int b, shift = 0, result = 0;
        do {
            b = encoded.charAt(index++) - 63;
            result |= (b & 0x1f) << shift;
            shift += 5;
        } while (b >= 0x20);
        int dlat = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
        lat += dlat;

        shift = 0;
        result = 0;
        do {
            b = encoded.charAt(index++) - 63;
            result |= (b & 0x1f) << shift;
            shift += 5;
        } while (b >= 0x20);
        int dlng = ((result & 1) != 0 ? ~(result >> 1) : (result >> 1));
        lng += dlng;

        LatLng p = new LatLng( (((double) lat / 1E5)),
                 (((double) lng / 1E5) ));
        poly.add(p);
    }

    return poly;
}

As direction call may take time so we will do all this in Asynchronous task. My Asynchronous task was

private class connectAsyncTask extends AsyncTask<Void, Void, String>{
    private ProgressDialog progressDialog;
    String url;
    connectAsyncTask(String urlPass){
        url = urlPass;
    }
    @Override
    protected void onPreExecute() {
        // TODO Auto-generated method stub
        super.onPreExecute();
        progressDialog = new ProgressDialog(MainActivity.this);
        progressDialog.setMessage("Fetching route, Please wait...");
        progressDialog.setIndeterminate(true);
        progressDialog.show();
    }
    @Override
    protected String doInBackground(Void... params) {
        JSONParser jParser = new JSONParser();
        String json = jParser.getJSONFromUrl(url);
        return json;
    }
    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);   
        progressDialog.hide();        
        if(result!=null){
            drawPath(result);
        }
    }
}

I hope it will help.

That is an object, not an array. So you would do:

var json = { cool: 34.33, alsocool: 45454 };
json.supercool = 3.14159;
console.dir(json);

See Rodolfo Neuber's reply for the best answer

(My original answer):

Derive from a control class and you can override the ProcessCmdKey method. Microsoft chose to omit these keys from KeyDown events because they affect multiple controls and move the focus, but this makes it very difficult to make an app react to these keys in any other way.

Look into git-reflog. It will list all the states it remembers (default is 30 days), and you can simply checkout the one you want. For example:

$ git init > /dev/null
$ touch a
$ git add .
$ git commit -m"Add file a" > /dev/null
$ echo 'foo' >> a
$ git commit -a -m"Append foo to a" > /dev/null
$ for i in b c d e; do echo $i >>a; git commit -a -m"Append $i to a" ;done > /dev/null
$ git reset --hard HEAD^^ > /dev/null
$ cat a
foo
b
c

For your input data:

let widthRange = new Array()
widthRange[46] = { min:0,  max:52 }
widthRange[61] = { min:52, max:70 }
widthRange[62] = { min:52, max:70 }
widthRange[63] = { min:52, max:70 }
widthRange[66] = { min:52, max:70 }
widthRange[90] = { min:70, max:94 }

Declarative approach:

const relevantKeys = [46,66,90]
const relevantValues = Object.keys(widthRange)
    .filter(index => relevantKeys.includes(parseInt(index)))
    .map(relevantIndex => widthRange[relevantIndex])

Object.keys to get the keys, using parseInt to cast them as numbers. filter to get only ones you want. map to build an array from the original object of just the indices you're after, since Object.keys loses the object values.

Debug:

console.log(widthRange)
console.log(relevantKeys)
console.log(relevantValues)

Maybe someone else has this problem at one point. If you use the UglifyJsPlugin in webpack 2 you need to explicitly specify the sourceMap flag. For example:

new webpack.optimize.UglifyJsPlugin({ sourceMap: true })

I always used the above solution without searching more after this. ;-)

However, today I came across something and thought of sharing it. :)

This feature is indeed available from API 1 and is called as ColorStateList, where we can supply a color to various states of Widgets (as we already know).

It is also very well documented, here.

Modify the show search method like this

showSearch(){
  this.show = !this.show;  
  setTimeout(()=>{ // this will make the execution after the above boolean has changed
    this.searchElement.nativeElement.focus();
  },0);  
}

In case you want to utilize .then() which has a subtle difference in comparison with .done() :

return $.post(url, payload)
.then(
    function (result, textStatus, jqXHR) {
        return result;
    },
    function (jqXHR, textStatus, errorThrown) {
        return console.error(errorThrown);
    });

With Underscore

Underscore provides a function _.mapObject to map the values and preserve the keys.

_.mapObject({ one: 1, two: 2, three: 3 }, function (v) { return v * 3; });

// => { one: 3, two: 6, three: 9 }

DEMO

With Lodash

Lodash provides a function _.mapValues to map the values and preserve the keys.

_.mapValues({ one: 1, two: 2, three: 3 }, function (v) { return v * 3; });

// => { one: 3, two: 6, three: 9 }

DEMO

To read the content of .hdf5 file as an array, you can do something as follow

> import numpy as np 
> myarray = np.fromfile('file.hdf5', dtype=float)
> print(myarray)

Something like this will do it. The for loop may need to be modified depending on which filenames you wish to capture.

for fspec1 in DET01-ABC-5_50-*.dat ; do
    fspec2=$(echo ${fspec1} | sed 's/-ABC-/-XYZ-/')
    mv ${fspec1} ${fspec2}
done

You should always test these scripts on copies of your data, by the way, and in totally different directories.

This worked for me. It's similar to previous answers but the path to the packages is different.

1. sudo easy_install -m
2. sudo rm -rf /Library/Python/2.7/site-packages/.egg

Plaform: MacOS High Sierra version 10.13.3

This is not an error, it is a warning from your Microsoft compiler.

Select your project and click "Properties" in the context menu.

In the dialog, chose Configuration Properties -> C/C++ -> Preprocessor

In the field PreprocessorDefinitions add ;_CRT_SECURE_NO_WARNINGS to turn those warnings off.

This should cover it:

 var event;
 event = document.createEvent('MouseEvents');
 event.initMouseEvent('mousedown', true, true, window);
 countries.dispatchEvent(event); //we use countries as it's referred to by ID - but this could be any JS element var

This could be bound for example to a keypress event, so when the element has focus the user can type and it will expand automatically...

--Context--

  modal.find("select").not("[readonly]").on("keypress", function(e) {

     if (e.keyCode == 13) {
         e.preventDefault();
         return false;
     }
     var event;
     event = document.createEvent('MouseEvents');
     event.initMouseEvent('mousedown', true, true, window);
     this.dispatchEvent(event);
 });

FrameLayout is not the better way to do this:

Use RelativeLayout instead. You can position the elements anywhere you like. The element that comes after, has the higher z-index than the previous one (i.e. it comes over the previous one).

Example:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent" android:layout_height="match_parent">
    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/colorPrimary"
        app:srcCompat="@drawable/ic_information"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="This is a text."
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        android:layout_margin="8dp"
        android:padding="5dp"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:background="#A000"
        android:textColor="@android:color/white"/>
</RelativeLayout>

OR

rm -rf `find /path/to/base/dir/* -type d -mtime +10`

Updated, faster version of it:

find /path/to/base/dir/* -mtime +10 -print0 | xargs -0 rm -f

You can use the following to convert string to int:

• CInt(String) for ints
• CDec(String) for decimals

For details refer to Type Conversion Functions (Visual Basic).

For some people this makes more sense if they see it in a couple different languages so I wrote an example in Java, and PHP on my page where I explain some of these modifiers. You might be thinking about this incorrectly.

You should look at my examples if it doesn't make sense below. Go here http://www.siteconsortium.com/h/D0000D.php

The bottom line though is that it is pretty much exactly what it says it is. It's a static member variable that is private. For example if you wanted to create a Singleton object why would you want to make the SingletonExample.instance variable public. If you did a person who was using the class could easily overwrite the value.

That's all it is.

    public class SingletonExample {
      private static SingletonExample instance = null;
      private static int value = 0;
      private SingletonExample() {
        ++this.value;
      }
      public static SingletonExample getInstance() {
        if(instance!=null)
        return instance;
        synchronized(SingletonExample.class) {
        instance = new SingletonExample();
        return instance;
        }
      }
      public void printValue() {
        System.out.print( this.value );
      }

      public static void main(String [] args) {
        SingletonExample instance = getInstance();
        instance.printValue();
        instance = getInstance();
        instance.printValue();
         }
    }

Yes, you can.

From cplusplus.com:

Because these functions are operator overloading functions, the usual way in which they are called is:

   strm >> variable;

Where strm is the identifier of a istream object and variable is an object of any type supported as right parameter. It is also possible to call a succession of extraction operations as:

   strm >> variable1 >> variable2 >> variable3; //...

which is the same as performing successive extractions from the same object strm.

Just replace strm with cin.

Xcode is free and good, which is lucky because it's pretty much the only option on the Mac.

Very simple:

Use COUNT_BIG(*) AS NumStreams

public DateTime DateCreated
{
   get
   {
      return (this.dateCreated == default(DateTime))
         ? this.dateCreated = DateTime.Now
         : this.dateCreated;
   }

   set { this.dateCreated = value; }
}
private DateTime dateCreated = default(DateTime);

You can trigger Jenkins builds remotely and to pass parameters by using the following query.

JENKINS_URL/job/job-name/buildWithParameters?token=TOKEN_NAME&param_name1=value&param_name1=value

JENKINS_URL (can be) = https://<your domain name or server address>

TOKE_NAME can be created using configure tab

use $gte and $lte to find between date data's in mongodb

var tomorrowDate = moment(new Date()).add(1, 'days').format("YYYY-MM-DD");
db.collection.find({"plannedDeliveryDate":{ $gte: new Date(tomorrowDate +"T00:00:00.000Z"),$lte: new Date(tomorrowDate + "T23:59:59.999Z")}})

Once you are quite good in Java SE (lets say you are able to pass SCJP), I'd suggest you get junior Java programmer job and improve yourself on real world problems

Since i stumbled on the post via google:

Try using npm ci it will be much than an npm install.

From the manual:

In short, the main differences between using npm install and npm ci are:

• The project must have an existing package-lock.json or npm-shrinkwrap.json.
• If dependencies in the package lock do not match those in package.json, npm ci will exit with an error, instead of updating the package lock.
• npm ci can only install entire projects at a time: individual dependencies cannot be added with this command.
• If a node_modules is already present, it will be automatically removed before npm ci begins its install.
• It will never write to package.json or any of the package-locks: installs are essentially frozen.

if you have scenario in which you have to remove more then one values from the foreach array in this case you have to pass value by reference in for each: I try to explain this scenario:

foreach ($manSkuQty as $man_sku => &$man_qty) {

               foreach ($manufacturerSkus as $key1 => $val1) {

  // some processing here and unset first loops entries                     
 //  here dont include again for next iterations
                           if(some condition)
                            unset($manSkuQty[$key1]);

                        }
               }
}

in second loop you want to unset first loops entries dont come again in the iteration for performance purpose or else then unset from memory as well because in memory they present and will come in iterations.

It can work well as you guess

python testMyCase.py MyCase.testItIsHot

And there is another way to just test testItIsHot:

    suite = unittest.TestSuite()
    suite.addTest(MyCase("testItIsHot"))
    runner = unittest.TextTestRunner()
    runner.run(suite)

Well, a for or while loop differs from a do while loop. A do while executes the statements atleast once, even if the condition turns out to be false.

The for loop you specified is absolutely correct.

Although i will do all the loops for you once again.

int sum = 0;
// for loop

for (int i = 1; i<= 100; i++){
    sum = sum + i;
}
System.out.println(sum);

// while loop

sum = 0;
int j = 1;

while(j<=100){
    sum = sum + j;
    j++;
}

System.out.println(sum);

// do while loop

sum = 0;
j = 1;

do{
    sum = sum + j;
    j++;
}
while(j<=100);

System.out.println(sum);

In the last case condition j <= 100 is because, even if the condition of do while turns false, it will still execute once but that doesn't matter in this case as the condition turns true, so it continues to loop just like any other loop statement.

we can upload image file by curl request by converting it base64 string.So in post we will send file string and then covert this in an image.

function covertImageInBase64()
{
    var imageFile = document.getElementById("imageFile").files;
    if (imageFile.length > 0)
    {
        var imageFileUpload = imageFile[0];
        var readFile = new FileReader();
        readFile.onload = function(fileLoadedEvent) 
        {
            var base64image = document.getElementById("image");
            base64image.value = fileLoadedEvent.target.result;
        };
        readFile.readAsDataURL(imageFileUpload);
    }
}

then send it in curl request

if(isset($_POST['image'])){
    $curlUrl='localhost/curlfile.php';  
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_URL, $curlUrl);
    curl_setopt($ch,CURLOPT_POST, 1);
    curl_setopt($ch,CURLOPT_POSTFIELDS, 'image='.$_POST['image']);
    $result = curl_exec($ch);
    curl_close($ch);
}

see here http://technoblogs.co.in/blog/How-to-upload-an-image-by-using-php-curl-request/118

$('#_SelectID').change(function () {
        var SelectedText = $('option:selected',this).text();
        var SelectedValue = $('option:selected',this).val();
});

You code should look like this:

public int getElement(int[] arrayOfInts, int index) {
    return arrayOfInts[index];
}

Main points here are method return type, it should match with array elements type and if you are working from main() - this method must be static also.

Simplest solution:

Convert array to list and you can get position of an element.

List<String> abcd  = Arrays.asList(yourArray);
int i = abcd.indexOf("abcd");

Other solution, you can iterator array:

int position = 0;
for (String obj : yourArray) {
    if (obj.equals("abcd") {
    return position;
    }
    position += 1;
} 

//OR
for (int i = 0; i < yourArray.length; i++) {
    if (obj.equals("abcd") {
       return i;
    }
}

You should be looking for the second tr that has the td that equals ' Color Digest ', then you need to look at either the following sibling of the first td in the tr, or the second td.

Try the following:

//tr[td='Color Digest'][2]/td/following-sibling::td[1]

or

//tr[td='Color Digest'][2]/td[2]

IntelliJ IDEA seems to have reorganized the configurations panel. Now one should go to Editor -> Color Scheme and click on the gears icon to import the theme they want from external .jar files.

You have several options if you use BufferedReader. This buffered reader is faster than Reader so you can wrap it.

BufferedReader reader = new BufferedReader(new FileReader(path));
reader.read(char[] buffer);

this reads line into char array. You have similar options. Look at documentation.

    Array.prototype.remove = function(start, end) {
        var n = this.slice((end || start) + 1 || this.length);
        return this.length = start < 0 ? this.length + start : start,
        this.push.apply(this, n)
    }

start and end can be negative. In that case they count from the end of the array.

If only start is specified, only one element is removed.

The function returns the new array length.

z = [0,1,2,3,4,5,6,7,8,9];

newlength = z.remove(2,6);

(8) [0, 1, 7, 8, 9]

z=[0,1,2,3,4,5,6,7,8,9];

newlength = z.remove(-4,-2);

(7) [0, 1, 2, 3, 4, 5, 9]

z=[0,1,2,3,4,5,6,7,8,9];

newlength = z.remove(3,-2);

(4) [0, 1, 2, 9]

Try:

Iterator<Map.Entry<String,String>> iter = testMap.entrySet().iterator();
while (iter.hasNext()) {
    Map.Entry<String,String> entry = iter.next();
    if("Sample".equalsIgnoreCase(entry.getValue())){
        iter.remove();
    }
}

With Java 1.8 and onwards you can do the above in just one line:

testMap.entrySet().removeIf(entry -> "Sample".equalsIgnoreCase(entry.getValue()));

Using foreach loop without key

foreach($array as $item) {
    echo $item['filename'];
    echo $item['filepath'];

    // to know what's in $item
    echo '<pre>'; var_dump($item);
}

Using foreach loop with key

foreach($array as $i => $item) {
    echo $item[$i]['filename'];
    echo $item[$i]['filepath'];

    // $array[$i] is same as $item
}

Using for loop

for ($i = 0; $i < count($array); $i++) {
    echo $array[$i]['filename'];
    echo $array[$i]['filepath'];
}

var_dump is a really useful function to get a snapshot of an array or object.

var iDiv = document.createElement('div');

iDiv.id = 'block';
iDiv.className = 'block';
document.getElementsByTagName('body')[0].appendChild(iDiv);

var div2 = document.createElement('div');

div2.className = 'block-2';
iDiv.appendChild(div2);

Try this. Oracle has this feature to distinguish the millennium years..

As you mentioned, if your column is a varchar, then the below query will yield you 1989..

select to_date(column_name,'dd/mm/rr') from table1;

When the format rr is used in year, the following would be done by oracle.

if rr->00 to 49 ---> result will be 2000 - 2049, if rr->50 to 99 ---> result will be 1950 - 1999

TO collect all item of an array and return a json object

collectData: function (arrayElements) {

        var main = [];

        for (var i = 0; i < arrayElements.length; i++) {
            var data = {};
            this.e = arrayElements[i];            
            data.text = arrayElements[i].text;
            data.val = arrayElements[i].value;
            main[i] = data;
        }
        return main;
    },

TO parse the same data we go through like this

dummyParse: function (json) {       
        var o = JSON.parse(json); //conerted the string into JSON object        
        $.each(o, function () {
            inner = this;
            $.each(inner, function (index) {
                alert(this.text)
            });
        });

}

Firstly, add path of visual studio common tools (c:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools) into the system path. To learn how to add a path into system path, please check this website: http://www.computerhope.com/issues/ch000549.htm. You just need to this once.

After that, whenever you need, open a command line and execute vsvars32.bat to add all required visual studio tools' paths into the system path.

Then, you can call nmake -f makefile.mak

PS: Path of visual studio common tools might be different in your system. Please change it accordingly.

u = urllib2.urlopen('http://myserver/inout-tracker', data)
h.request('POST', '/inout-tracker/index.php', data, headers)

Using the path /inout-tracker without a trailing / doesn't fetch index.php. Instead the server will issue a 302 redirect to the version with the trailing /.

Doing a 302 will typically cause clients to convert a POST to a GET request.

At runtime, you know what style you want your button to have. So beforehand, in xml in the layout folder, you can have all ready to go buttons with the styles you need. So in the layout folder, you might have a file named: button_style_1.xml. The contents of that file might look like:

<?xml version="1.0" encoding="utf-8"?>
<Button
    android:id="@+id/styleOneButton"
    style="@style/FirstStyle" />

If you are working with fragments, then in onCreateView you inflate that button, like:

Button firstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);

where container is the ViewGroup container associated with the onCreateView method you override when creating your fragment.

Need two more such buttons? You create them like this:

Button secondFirstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);
Button thirdFirstStyleBtn = (Button) inflater.inflate(R.layout.button_style_1, container, false);

You can customize those buttons:

secondFirstStyleBtn.setText("My Second");
thirdFirstStyleBtn.setText("My Third");

Then you add your customized, stylized buttons to the layout container you also inflated in the onCreateView method:

_stylizedButtonsContainer = (LinearLayout) rootView.findViewById(R.id.stylizedButtonsContainer);

_stylizedButtonsContainer.addView(firstStyleBtn);
_stylizedButtonsContainer.addView(secondFirstStyleBtn);
_stylizedButtonsContainer.addView(thirdFirstStyleBtn);

And that's how you can dynamically work with stylized buttons.

The following should suffice:

[^ ]

If you want to expand that to anything but white-space (line breaks, tabs, spaces, hard spaces):

[^\s]

or

\S  # Note this is a CAPITAL 'S'!

I think the best option is:

1. Create a model class as config schema

2. Register in DI: services.Configure(Configuration.GetSection("democonfig"));

3. Get the values as model object from DI in your controller:

   private readonly your_model myConfig;
   public DemoController(IOptions<your_model> configOps)
   {
       this.myConfig = configOps.Value;
   }
   

quite simple:

ul.yourlist li { float:left; }

or

ul.yourlist li { display:inline; }

includes

Object.keys(x).includes('y');

The Array.prototype.includes() method determines whether an array includes a certain value among its entries, returning true or false as appropriate.

and

Object.keys() returns an array of strings that represent all the enumerable properties of the given object.

.hasOwnProperty() and the ES6+ .? -optional-chaining like: if (x?.y) are very good 2020+ options as well.

You should map your virtual network drive in Windows.

1. Open command prompt in Windows (VirtualBox)
2. Execute: net use x: \\vboxsvr\<your_shared_folder_name>
3. You should see new drive X: in My Computer

In your case execute net use x: \\vboxsvr\win7

This modification of a_horse_with_no_name's answer will give you the blocking queries in addition to just the blocked sessions:

SELECT
    activity.pid,
    activity.usename,
    activity.query,
    blocking.pid AS blocking_id,
    blocking.query AS blocking_query
FROM pg_stat_activity AS activity
JOIN pg_stat_activity AS blocking ON blocking.pid = ANY(pg_blocking_pids(activity.pid));

You can use any of the following methods for setting the Drawable on TextView:

1- setCompoundDrawablesWithIntrinsicBounds(int, int, int, int)

2- setCompoundDrawables(Left_Drawable, Top_Drawable, Right_Drawable, Bottom_Drawable)

And to get drawable from resources you can use:

getResources().getDrawable(R.drawable.your_drawable_id);

This is actually very simple. It is much easier to find unique values, if the values are sorted first:

function sort_unique(arr) {
  if (arr.length === 0) return arr;
  arr = arr.sort(function (a, b) { return a*1 - b*1; });
  var ret = [arr[0]];
  for (var i = 1; i < arr.length; i++) { //Start loop at 1: arr[0] can never be a duplicate
    if (arr[i-1] !== arr[i]) {
      ret.push(arr[i]);
    }
  }
  return ret;
}
console.log(sort_unique(['237','124','255','124','366','255']));
//["124", "237", "255", "366"]

In my search for hotel APIs I have found only one API giving unrestricted open access to their hotel database and allowing you to book their hotels:

Expedia's EAN http://developer.ean.com/

You need to sign for their affiliate program, which is very easy. You get immediate access to their hotel databases plus you can make availability/booking requests with several response options, including JSON, which is more convenient and lightweight than the (unfortunately) more widespread XML.

As you immediately access their API, you can start developing and testing, but still need their approval to launch the site, basically to make sure it provides the needed quality and security, which is reasonable.

They also offer "deep linking", i.e. you may customize your requests by adding parameters. Then if it sufficient for your purpose (for mine it is not), you don't even need to store their content on your server.

I have also signed for HotelsCombined program: (link removed as this site doesn't seem to let me put more links)

However, they do not immediately allow you to use their API even for testing. From their answer:

"Apologies for the inconvenience caused, but it’s simply a business decision to limit access to our rich hotel content. Please kindly check back within the next 2-3 months, where we will be able to judge your traffic, and in turn judge your status on standard data feeds."

I have also signed for Booking.com affiliate program: (link removed as this site doesn't seem to let me put more links)

Unfortunately, again, they limit access, from their answer: "Please do note that, since there's a high amount of time and cost involved in the XML integration, we are only able to offer the XML integration to a small amount of partners with a high potential."

I did not explore Tripadvisor as they seem only to offer top 10 hotels and only as widgets, but most importantly for me, they wouldn't allow booking through them.

I've checked the hotelbase.org mentioned above, they have very extensive list but not as rich as by Expedia, also they don't seem to have images and don't allow booking either.

Try to change where Member class

public function users() {
    return $this->hasOne('User');
} 

return $this->belongsTo('User');

If you use an absolute path such as ("/index.jsp"), there is no difference.

If you use relative path, you must use HttpServletRequest.getRequestDispatcher(). ServletContext.getRequestDispatcher() doesn't allow it.

For example, if you receive your request on http://example.com/myapp/subdir,

    RequestDispatcher dispatcher = 
        request.getRequestDispatcher("index.jsp");
    dispatcher.forward( request, response ); 

Will forward the request to the page http://example.com/myapp/subdir/index.jsp.

In any case, you can't forward request to a resource outside of the context.

When creating constants in a jar file, it is often helpful to let users extend enum values. We used enums for PropertyFile keys and got stuck because nobody could add any new ones! Below would have worked much better.

Given:

public interface Color {
  String fetchName();
}

and:

public class MarkTest {

  public static void main(String[] args) {
    MarkTest.showColor(Colors.BLUE);
    MarkTest.showColor(MyColors.BROWN);
  }

  private static void showColor(Color c) {
    System.out.println(c.fetchName());
  }
}

one could have one enum in the jar:

public enum Colors implements Color {
  BLUE, RED, GREEN;
  @Override
  public String fetchName() {
    return this.name();
  }
}

and a user could extend it to add his own colors:

public enum MyColors implements Color {
  BROWN, GREEN, YELLOW;
  @Override
  public String fetchName() {
    return this.name();
  }
}

Create and edit the jupyter notebook config file with the following steps:

• Launch Anaconda Prompt
• Type jupyter notebook --generate-config
• Type notepad path_to_file/jupyter_notebook_config.py to open it (change path_to_file)
• Modify #c.NotebookApp.browser = '' to c.NotebookApp.browser = 'C:/Program Files (x86)/Google/Chrome/Application/chrome.exe %s'
• Save the file and close it

Jupyter notebook will now use Chrome.

There are several ways. One way is to use save() to save the exact object. e.g. for data frame foo:

save(foo,file="data.Rda")

Then load it with:

load("data.Rda")

You could also use write.table() or something like that to save the table in plain text, or dput() to obtain R code to reproduce the table.

I prefer the following one-liner approach using str.rsplit():

my_filename.rsplit('.', 1)[0] + '.jpg'

Example:

>>> my_filename = '/home/user/somefile.txt'
>>> my_filename.rsplit('.', 1)
>>> ['/home/user/somefile', 'txt']

I found that I can run this command:

notepad $((Split-Path $profile -Parent) + "\profile.ps1")

and it opens my default powershell profile (at least when using Terminal for Windows). I found that here.

Then add an alias. For example, here is my alias of jn for jupyter notebook (I hate typing out the cumbersome jupyter notebook every time):

Set-Alias -Name jn -Value C:\Users\words\Anaconda3\Scripts\jupyter-notebook.exe

The accepted answer let keyExists = dict[key] != nil will not work if the Dictionary contains the key but has a value of nil.

If you want to be sure the Dictionary does not contain the key at all use this (tested in Swift 4).

if dict.keys.contains(key) {
  // contains key
} else { 
  // does not contain key
}

const tifOptions = [];

for (const [key, value] of Object.entries(tifs)) {
    tifOptions.push(<option value={key} key={key}>{value}</option>);
}

return (
   <select id="tif" name="tif" onChange={this.handleChange}>  
      { tifOptions }          
   </select>
)

You can use jQuery's .eq() method to get the element with a certain index.

$('ul li').eq(index).css({'background-color':'#343434'});

First zip or gzip the folders:
Use the following command:

zip -r NameYouWantForZipFile.zip foldertozip/

or

tar -pvczf BackUpDirectory.tar.gz /path/to/directory

for gzip compression use SCP:

scp [email protected]:~/serverpath/public_html ~/Desktop

I had similar issue recently. Regional settings were properly setup both in app and database server. However, execution of SQL resulted in

"The conversion of a varchar data type to a datetime data type resulted in an out-of-range value".

The problem was the default language of the db user.

To check or change it in SSMS go to Security -> Logins and right-click the username of the user that runs the queries. Select properties -> general and make sure the default language at the bottom of the dialog is what you expect.

Repeat this for all users that run queries.

The ConcurrentHashMap is very similar to the HashMap class, except that ConcurrentHashMap offers internally maintained concurrency. It means you do not need to have synchronized blocks when accessing ConcurrentHashMap in multithreaded application.

To get all key-value pairs in ConcurrentHashMap, below code which is similar to your code works perfectly:

//Initialize ConcurrentHashMap instance
ConcurrentHashMap<String, Integer> m = new ConcurrentHashMap<String, Integer>();

//Print all values stored in ConcurrentHashMap instance
for each (Entry<String, Integer> e : m.entrySet()) {
  System.out.println(e.getKey()+"="+e.getValue());
}

Above code is reasonably valid in multi-threaded environment in your application. The reason, I am saying 'reasonably valid' is that, above code yet provides thread safety, still it can decrease the performance of application.

Hope this helps you.

If you have access to our webroot, create a file asdf.php with

<?php phpinfo(); ?>

in it and point your webbrowser to it. You should see all info in the first section.

• Configuration File (php.ini) Path
• Loaded Configuration File
• Scan this dir for additional .ini files
• Additional .ini files parsed

This works for any php application and is therefore the universal way to find our php.ini

With this function you can filter a multidimensional array

function filter_array_keys($array,$filter_keys=array()){

    $l=array(&$array);
    $c=1;
    //This first loop will loop until the count var is stable//
    for($r=0;$r<$c;$r++){
        //This loop will loop thru the child element list//
        $keys = array_keys($l[$r]);

        for($z=0;$z<count($l[$r]);$z++){
            $object = &$l[$r][$keys[$z]];

            if(is_array($object)){
                $i=0;
                $keys_on_array=array_keys($object);
                $object=array_filter($object,function($el) use(&$i,$keys_on_array,$filter_keys){
                    $key = $keys_on_array[$i];
                    $i++;

                    if(in_array($key,$filter_keys) || is_int($key))return false;                
                    return true;                        
                });
            }

            if(is_array($l[$r][$keys[$z]])){
                $l[] = &$l[$r][$keys[$z]];
                $c++;
            }//IF           
        }//FOR
    }//FOR  

    return $l[0];

}

I followed below link to fix this problem. Make sure to enable following Module.

Google changed their policies last month regarding auto-play inside Chrome. Please see this announcement.

They do, however, allow auto-play if you are embedding a video and it is muted. You can add the muted property and it should allow the video to start playing.

<video autoplay controls muted>
  <source src="movie.mp4" type="video/mp4">
  <source src="movie.ogg" type="video/ogg">
  Your browser does not support the video tag.
</video>

A really simple way to achieve this would be:

//instance variable
List<View>itemViewList = new ArrayList<>();

//OnCreateViewHolderMethod
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {    
    final View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_row, parent, false);
    final MyViewHolder myViewHolder = new MyViewHolder(itemView);

    itemViewList.add(itemView); //to add all the 'list row item' views

    //Set on click listener for each item view
    itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            for(View tempItemView : itemViewList) {
                /** navigate through all the itemViews and change color
                of selected view to colorSelected and rest of the views to colorDefault **/
                if(itemViewList.get(myViewHolder.getAdapterPosition()) == tempItemView) {
                    tempItemView.setBackgroundResource(R.color.colorSelected);
                }
                else{
                    tempItemView.setBackgroundResource(R.color.colorDefault);
                }
            }
        }
    });
    return myViewHolder;
}

UPDATE

The method above may ruin some default attributes of the itemView, in my case, i was using CardView, and the corner radius of the card was getting removed on click.

Better solution:

//instance variable
List<CardView>cardViewList = new ArrayList<>();

public class MyViewHolder extends RecyclerView.ViewHolder {
        CardView cardView; //THIS IS MY ROOT VIEW
        ...

        public MyViewHolder(View view) {
            super(view);
            cardView = view.findViewById(R.id.row_item_card);
            ...
        }
}

@Override
    public void onBindViewHolder(final MyViewHolder holder, int position) {
        final OurLocationObject locationObject = locationsList.get(position);
        ...

        cardViewList.add(holder.cardView); //add all the cards to this list

        holder.cardView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //All card color is set to colorDefault
                for(CardView cardView : cardViewList){
                cardView.setCardBackgroundColor(context.getResources().getColor(R.color.colorDefault));
                }
                //The selected card is set to colorSelected
                holder.cardView.setCardBackgroundColor(context.getResources().getColor(R.color.colorSelected));
            }
        });
}

UPDATE 2 - IMPORTANT

onBindViewHolder method is called multiple times, and also every time the user scrolls the view out of sight and back in sight! This will cause the same view to be added to the list multiple times which may cause problems and minor delay in code executions!

To fix this, change

cardViewList.add(holder.cardView);

to

if (!cardViewList.contains(holder.cardView)) {
    cardViewList.add(holder.cardView);
}

You can use

if errorlevel 1 echo Unsuccessful

in some cases. This depends on the last command returning a proper exit code. You won't be able to tell that there is anything wrong if your program returns normally even if there was an abnormal condition.

Caution with programs like Robocopy, which require a more nuanced approach, as the error level returned from that is a bitmask which contains more than just a boolean information and the actual success code is, AFAIK, 3.

Call this function onclick of button

/*pass whatever you want instead of id */
function doConfirm(id) {
    var ok = confirm("Are you sure to Delete?");
    if (ok) {
        if (window.XMLHttpRequest) {
            // code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp = new XMLHttpRequest();
        } else {
            // code for IE6, IE5
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        }

        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                window.location = "create_dealer.php";
            }
        }

        xmlhttp.open("GET", "delete_dealer.php?id=" + id);
        // file name where delete code is written
        xmlhttp.send();
    }
}

import { FormsModule } from '@angular/forms'; //<<<< import it here

BrowserModule, FormsModule //<<<< and here

So simply looks for app.module.ts or another module file and make sure you have FormsModule imported in...

A common way to achieve what you desire is to use the ADB pull command.

Another way I prefer in most cases is to copy the database by code to SD card:

try {
    File sd = Environment.getExternalStorageDirectory();

    if (sd.canWrite()) {
        String currentDBPath = "/data/data/" + getPackageName() + "/databases/yourdatabasename";
        String backupDBPath = "backupname.db";
        File currentDB = new File(currentDBPath);
        File backupDB = new File(sd, backupDBPath);

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

}

Don't forget to set the permission to write on SD in your manifest, like below.

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

kubectl exec -it POD_NAME -c CONTAINER_NAME bash - then kill 1

Assuming the container is run as root which is not recommended.

In my case when I changed the application config, I had to reboot the container which was used in a sidecar pattern, I would kill the PID for the spring boot application which is owned by the docker user.

If you want to do it by ClassName you could do:

<script type="text/javascript">
function hideTd(className){
    var elements;

    if (document.getElementsByClassName)
    {
        elements = document.getElementsByClassName(className);
    }
    else
    {
        var elArray = [];
        var tmp = document.getElementsByTagName(elements);  
        var regex = new RegExp("(^|\\s)" + className+ "(\\s|$)");
        for ( var i = 0; i < tmp.length; i++ ) {

            if ( regex.test(tmp[i].className) ) {
                elArray.push(tmp[i]);
            }
        }

        elements = elArray;
    }

    for(var i = 0, i < elements.length; i++) {
       if( elements[i].textContent == ''){
          elements[i].style.display = 'none';
       } 
    }

  }
</script>

I found 100% working Concept for me:

# Options is required by Many Hosting
Options +MultiViews

RewriteEngine on

# For .php & .html URL's:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ $1.php [NC,L]
RewriteRule ^([^\.]+)$ $1.html [NC,L]

Use this code in Root of your website .htaccess file like :

offline - wamp\www\YourWebDir

online - public_html/

If it doesn't work correct, then change the settings of your Wamp Server: 1) Left click WAMP icon 2) Apache 3) Apache Modules 4) Left click rewrite_module

I would try the usual remedial things: - Run Rob Bovey's VBA Code Cleaner on your VBA Code - remove all addins on the users PC, particularly COM and .NET addins - Delete all the users .EXD files (MSoft Update incompatibilities) - Run Excel Detect & Repair on the users system - check the size of the user's .xlb file (should be 20-30K) - Reboot then delete all the users Temp files

i was facing this problem and i checked all the answers and nothing worked for me, but then i reset mail.php and didn't touch it and set the mail server from .env file and it worked perfectly, hope this will save the time for someone :).

As already discussed, the best way to dump the array into a CSV file is by using .savetxt(...)method. However, there are certain things we should know to do it properly.

For example, if you have a numpy array with dtype = np.int32 as

   narr = np.array([[1,2],
                 [3,4],
                 [5,6]], dtype=np.int32)

and want to save using savetxt as

np.savetxt('values.csv', narr, delimiter=",")

It will store the data in floating point exponential format as

1.000000000000000000e+00,2.000000000000000000e+00
3.000000000000000000e+00,4.000000000000000000e+00
5.000000000000000000e+00,6.000000000000000000e+00

You will have to change the formatting by using a parameter called fmt as

np.savetxt('values.csv', narr, fmt="%d", delimiter=",")

to store data in its original format

Saving Data in Compressed gz format

Also, savetxt can be used for storing data in .gz compressed format which might be useful while transferring data over network.

We just need to change the extension of the file as .gz and numpy will take care of everything automatically

np.savetxt('values.gz', narr, fmt="%d", delimiter=",")

Hope it helps

you can use download attribute to force download a file:

<a href="https://test.com/aaa.exe" download>click here to download</a>

Your problem is that you have declare twice the exec-maven-plugin :

1. On Windows: Add the path to the library to the PATH environment variable.
2. On Linux: Add the path to the library to the LD_LIBRARY_PATH environment variable.
3. On Mac: Add the path to the library to the DYLD_LIBRARY_PATH environment variable.

java.library.path is initilized with the values of the variables above on its corresponding platform.

This should work on any IDE.

You can test if the value is what you expect by calling java -XshowSettings:properties

use Illuminate\Support\Facades\Hash;
if(Hash::check($plain-text,$hashed-text))
    {
       return true;
    }
    else

All aforementioned suggestions use %s placeholder for subject. I'll recommend to use %B because %s formatting preserves new lines and multiple lines commit message appears squashed.

git log --pretty=format:"%h%x09%an%x09%ai%x09%B"

For whatever it's worth now: here is yet another solution:

• create two divs within a display: inline-block
• in the first div, put a table with only the header (header table tabhead)
• in the 2nd div, put a table with header and data (data table / full table tabfull)
• use JavaScript, use setTimeout(() => {/*...*/}) to execute code after render / after filling the table with results from fetch
• measure the width of each th in the data table (using clientWidth)
• apply the same width to the counterpart in the header table
• set visibility of the header of the data table to hidden and set the margin top to -1 * height of data table thead pixels

With a few tweaks, this is the method to use (for brevity / simplicity, I used d3js, the same operations can be done using plain DOM):

setTimeout(() => { // pass one cycle
  d3.select('#tabfull')
    .style('margin-top', (-1 * d3.select('#tabscroll').select('thead').node().getBoundingClientRect().height) + 'px')
    .select('thead')
      .style('visibility', 'hidden');
  let widths=[]; // really rely on COMPUTED values
  d3.select('#tabfull').select('thead').selectAll('th')
    .each((n, i, nd) => widths.push(nd[i].clientWidth));
  d3.select('#tabhead').select('thead').selectAll('th')
    .each((n, i, nd) => d3.select(nd[i])

Waiting on render cycle has the advantage of using the browser layout engine thoughout the process - for any type of header; it's not bound to special condition or cell content lengths being somehow similar. It also adjusts correctly for visible scrollbars (like on Windows)

ModeleREP#getTimeSeries() have to be with @Transient annotation. That would help.

Using Lodash

const values = [5, 5, 5, 2, 2, 2, 2, 2, 9, 4];
const frequency = _.map(_.groupBy(values), val => ({ value: val[0], frequency: val.length }));
console.log(frequency);

Calling EntityManager#flush does have side-effects. It is conveniently used for entity types with generated ID values (sequence values): such an ID is available only upon synchronization with underlying persistence layer. If this ID is required before the current transaction ends (for logging purposes for instance), flushing the session is required.

I figured out the demo and implemented it the following way:

$.datepicker.setDefaults(
  $.extend(
    {'dateFormat':'dd-mm-yy'},
    $.datepicker.regional['nl']
  )
);

I needed to set the default for the dateformat too ...

Adding the @ElementCollection to the List field solved this issue:

@Column
@ElementCollection(targetClass=Integer.class)
private List<Integer> countries;

Psuedo-code:

1. Split the strings by the path seperator ("/")
2. Find the greatest common path by iterating thru the result of the split string (so you'd end up with "/var/data" or "/a" in your two examples)
3. return "." + whicheverPathIsLonger.substring(commonPath.length);

You can use the position:fixed;, but without set left and top. Then you will push it to the right using margin-left, to position it in the right position you wish.

Check a demo here: http://jsbin.com/icili5

One reason it is not preferable to write the string like 'string +"Value"+ string' is because of Localization. In cases where localization is occurring we want the localized string to be correctly formatted, which could be very different from the language being coded in.

For example we need to show the following error in different languages:

MessageBox.Show(String.Format(ErrorManager.GetError("PIDV001").Description, proposalvalue.ProposalSource)

where

'ErrorCollector.GetError("ERR001").ErrorDescription' returns a string like "Your ID {0} is not valid". This message must be localized in many languages. In that case we can't use + in C#. We need to follow string.format.

What Anthony says is absolutely correct, but I'd like to add that your experience will likely show a lot better performance and efficiency (due not to fpm-vs-fcgi but more to the implementation of your httpd).

For example, I had a quad-core machine running lighttpd + fcgi humming along nicely. I upgraded to a 16-core machine to cope with growth, and two things exploded: RAM usage, and segfaults. I found myself restarting lighttpd every 30 minutes to keep the website up.

I switched to php-fpm and nginx, and RAM usage dropped from >20GB to 2GB. Segfaults disappeared as well. After doing some research, I learned that lighttpd and fcgi don't get along well on multi-core machines under load, and also have memory leak issues in certain instances.

Is this due to php-fpm being better than fcgi? Not entirely, but how you hook into php-fpm seems to be a whole heckuva lot more efficient than how you serve via fcgi.

If you are using bash you can try alias:

into the .bashrc file add this line:

alias p='cd /home/serdar/my_new_folder/path/'

when you write "p" on the command line, it will change the directory.

You can use a Union.

This will return the results of the queries in separate rows.

First you must make sure that both queries return identical columns.

Then you can do :

SELECT tableA.Id, tableA.Name, [tableB].Username AS Owner, [tableB].ImageUrl, [tableB].CompanyImageUrl, COUNT(tableD.UserId) AS Number
FROM tableD 
RIGHT OUTER JOIN [tableB] 
INNER JOIN tableA ON [tableB].Id = tableA.Owner ON tableD.tableAId = tableA.Id 
GROUP BY tableA.Name, [tableB].Username, [tableB].ImageUrl, [tableB].CompanyImageUrl

UNION

SELECT tableA.Id, tableA.Name,  '' AS Owner, '' AS ImageUrl, '' AS CompanyImageUrl, COUNT([tableC].Id) AS Number
FROM 
[tableC] 
RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id GROUP BY tableA.Id, tableA.Name

As has been mentioned, both queries return quite different data. You would probably only want to do this if both queries return data that could be considered similar.

SO

You can use a Join

If there is some data that is shared between the two queries. This will put the results of both queries into a single row joined by the id, which is probably more what you want to be doing here...

You could do :

SELECT tableA.Id, tableA.Name, [tableB].Username AS Owner, [tableB].ImageUrl, [tableB].CompanyImageUrl, COUNT(tableD.UserId) AS NumberOfUsers, query2.NumberOfPlans
FROM tableD 
RIGHT OUTER JOIN [tableB] 
INNER JOIN tableA ON [tableB].Id = tableA.Owner ON tableD.tableAId = tableA.Id 


INNER JOIN 
  (SELECT tableA.Id, COUNT([tableC].Id) AS NumberOfPlans 
   FROM [tableC] 
   RIGHT OUTER JOIN tableA ON [tableC].tableAId = tableA.Id 
   GROUP BY tableA.Id, tableA.Name) AS query2 
ON query2.Id = tableA.Id

GROUP BY tableA.Name, [tableB].Username, [tableB].ImageUrl, [tableB].CompanyImageUrl

Just added to the answer from Kunal Mathur and an answer to @mockash, since I cannot comment due to lack of reputation.

Before you type: pip install package_name, you need to change the directory to the folder where pip.exe is. for example:

Open Visual C++ 2015 x86 x64 Cross Build Tools Command Prompt--> change directory cd C:\Users\Test\AppData\Local\Programs\Python\Python36-32\Scripts-->Type: pip install package_name

But the weird thing is I can only successfully install via 'Visual C++ 2015 x64 x86' not 'x86 x64'

Are methods using FOR XML PATH like below really that slow? Itzik Ben-Gan writes that this method has good performance in his T-SQL Querying book (Mr. Ben-Gan is a trustworthy source, in my view).

create table #t (id int, name varchar(20))

insert into #t
values (1, 'Matt'), (1, 'Rocks'), (2, 'Stylus')

select  id
        ,Names = stuff((select ', ' + name as [text()]
        from #t xt
        where xt.id = t.id
        for xml path('')), 1, 2, '')
from #t t
group by id

To update a table in your .dbml-diagram with, for example, added columns, do this:

1. Update your SQL Server Explorer window.
2. Drag the "new" version of your table into the .dbml-diagram (report1 in the picture below).

3. Mark the added columns in the new version of the table, press Ctrl+C to copy the added columns.

4. Click the "old" version of your table and press Ctrl+V to paste the added columns into the already present version of the table.

base is the number that you want to power up, n is the power, we return 1 if n is 0, and we return the base if the n is 1, if the conditions are not met, we use the formula base*(powerN(base,n-1)) eg: 2 raised to to using this formula is : 2(base)*2(powerN(base,n-1)).

public int power(int base, int n){
   return n == 0 ? 1 : (n == 1 ? base : base*(power(base,n-1)));
}

The fastest way, to get a hash string for password store purposes, is a following code:

    internal static string GetStringSha256Hash(string text)
    {
        if (String.IsNullOrEmpty(text))
            return String.Empty;

        using (var sha = new System.Security.Cryptography.SHA256Managed())
        {
            byte[] textData = System.Text.Encoding.UTF8.GetBytes(text);
            byte[] hash = sha.ComputeHash(textData);
            return BitConverter.ToString(hash).Replace("-", String.Empty);
        }
    }

Remarks:

• if the method is invoked often, the creation of sha variable should be refactored into a class field;
• output is presented as encoded hex string;

There might be a chance that you have install node.js while your visual studio code was open. Once node.js is install successfully, Simply close the VS Code and Start it again. It will work. Thank you

Yes, it is used all the time for testing. It is very likely that the testing framework uses .equals() for comparisons such as these.

Below is a link explaining the "string equality mistake". Essentially, strings in Java are objects, and when you compare object equality, typically they are compared based on memory address, and not by content. Because of this, two strings won't occupy the same address, even if their content is identical, so they won't match correctly, even though they look the same when printed.

http://blog.enrii.com/2006/03/15/java-string-equality-common-mistake/

It is possibly to use the flag -o,--offline "Work offline" to prevent that.

Like this:

maven compile -o

You're looking for the /Y switch.

All of the above answers were perfectly clear and complete, but just for the record I'd like to confirm that the meaning of * and ** in python has absolutely no similarity with the meaning of similar-looking operators in C.

They are called the argument-unpacking and keyword-argument-unpacking operators.

I use static final to declare constants and go with the ALL_CAPS naming notation. I have seen quite a few real life instances where all constants are bunched together into an interface. A few posts have rightly called that a bad practice, primarily because that's not what an interface is for. An interface should enforce a contract and should not be a place to put unrelated constants in. Putting it together into a class that cannot be instantiated (through a private constructor) too is fine if the constant semantics don't belong to a specific class(es). I always put a constant in the class that it's most related to, because that makes sense and is also easily maintainable.

Enums are a good choice to represent a range of values, but if you are storing standalone constants with an emphasis on the absolute value (eg. TIMEOUT = 100 ms) you can just go for the static final approach.

if you need to select multiple columns from dataframe use 2 pairs of square brackets eg.

df[["product_id","customer_id","store_id"]]

ps x | grep SCREEN

screen -A -m -d php make_something.php

If for whatever reason you cannot have the files hosted from a webserver and still need some sort of way of loading partials, you can resort to using the ngTemplate directive.

This way, you can include your markup inside script tags in your index.html file and not have to include the markup as part of the actual directive.

Add this to your index.html

<script type='text/ng-template' id='tpl-productColour'>
 <div class="list-group-item">
    <h3>Hello <em class="pull-right">Brother</em></h3>
</div>
</script>

Then, in your directive:

app.directive('productColor', function() {
      return {
          restrict: 'E', //Element Directive
          //template: 'tpl-productColour'
          templateUrl: 'tpl-productColour'
      };
   }
  );

Once you're logged into phpmyadmin look on the top navigation for "Settings" and click that then:

"Features" >

Unfortunately changing it through the UI means that the changes don't persist between logins.

I was getting this error on amazon.ca, meetup.com, and the Symantec homepage.

I went to the update page in the Chrome browser (it was at 53.*) and checked for an upgrade, and it showed there was no updates available. After asking around my office, it turns out the latest version was 55 but I was stuck on 53 for some reason.

After upgrading (had to manually download from the Chrome website) the issues were gone!

According to http://khason.net/blog/how-to-use-systemdrawingbitmap-hbitmap-in-wpf/

   [DllImport("gdi32")]
   static extern int DeleteObject(IntPtr o);

   public static BitmapSource loadBitmap(System.Drawing.Bitmap source)
   {
       IntPtr ip = source.GetHbitmap();
       BitmapSource bs = null;
       try
       {
           bs = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(ip, 
              IntPtr.Zero, Int32Rect.Empty, 
              System.Windows.Media.Imaging.BitmapSizeOptions.FromEmptyOptions());
       }
       finally
       {
           DeleteObject(ip);
       }

       return bs;
   }

It gets System.Drawing.Bitmap (from WindowsBased) and converts it into BitmapSource, which can be actually used as image source for your Image control in WPF.

image1.Source = YourUtilClass.loadBitmap(SomeBitmap);

Actually, we're now in globalized world of 21st century and people no longer communicate using ASCII only so when anwering question about "is it letters only" you need to take into account letters from non-ASCII alphabets as well. Python has a pretty cool unicodedata library which among other things allows categorization of Unicode characters:

unicodedata.category('?')
'Lo'

unicodedata.category('A')
'Lu'

unicodedata.category('1')
'Nd'

unicodedata.category('a')
'Ll'

The categories and their abbreviations are defined in the Unicode standard. From here you can quite easily you can come up with a function like this:

def only_letters(s):
    for c in s:
        cat = unicodedata.category(c)
        if cat not in ('Ll','Lu','Lo'):
            return False
    return True

And then:

only_letters('Bzdrezylo')
True

only_letters('He7lo')
False

As you can see the whitelisted categories can be quite easily controlled by the tuple inside the function. See this article for a more detailed discussion.

All of the current answers on this thread must have been a bit dated. As of pandas version 0.24.0, the .to_flat_index() does what you need.

From panda's own documentation:

MultiIndex.to_flat_index()

Convert a MultiIndex to an Index of Tuples containing the level values.

A simple example from its documentation:

import pandas as pd
print(pd.__version__) # '0.23.4'
index = pd.MultiIndex.from_product(
        [['foo', 'bar'], ['baz', 'qux']],
        names=['a', 'b'])

print(index)
# MultiIndex(levels=[['bar', 'foo'], ['baz', 'qux']],
#           codes=[[1, 1, 0, 0], [0, 1, 0, 1]],
#           names=['a', 'b'])

Applying to_flat_index():

index.to_flat_index()
# Index([('foo', 'baz'), ('foo', 'qux'), ('bar', 'baz'), ('bar', 'qux')], dtype='object')

Using it to replace existing pandas column

An example of how you'd use it on dat, which is a DataFrame with a MultiIndex column:

dat = df.loc[:,['name','workshop_period','class_size']].groupby(['name','workshop_period']).describe()
print(dat.columns)
# MultiIndex(levels=[['class_size'], ['count', 'mean', 'std', 'min', '25%', '50%', '75%', 'max']],
#            codes=[[0, 0, 0, 0, 0, 0, 0, 0], [0, 1, 2, 3, 4, 5, 6, 7]])

dat.columns = dat.columns.to_flat_index()
print(dat.columns)
# Index([('class_size', 'count'),  ('class_size', 'mean'),
#     ('class_size', 'std'),   ('class_size', 'min'),
#     ('class_size', '25%'),   ('class_size', '50%'),
#     ('class_size', '75%'),   ('class_size', 'max')],
#  dtype='object')

You can create the Python dictionary and serialize it to JSON in one line and it's not even ugly.

my_json_string = json.dumps({'key1': val1, 'key2': val2})

Apart from using custom images for bullets, you can also style the ul or li elements one way and then style the contents differently, as seen here.

The benefit is the lack of images for one thing, and also the added control. The disadvantage is that it tends to involve non-semantic markup, except in this case where the anchors are required already.

String s = new String("FFFF") creates 2 objects: "FFFF" string and String object, which point to "FFFF" string, so it is like pointer to pointer (reference to reference, I am not keen with terminology).

It is said you should never use new String("FFFF")

In MySQL, use the JSON type.

Contra the answers above, the SQL standard has included array types for almost twenty years; they are useful, even if MySQL has not implemented them.

In your example, however, you'll likely want to create three tables: person and fruit, then person_fruit to join them.

DROP TABLE IF EXISTS person_fruit;
DROP TABLE IF EXISTS person;
DROP TABLE IF EXISTS fruit;

CREATE TABLE person (
  person_id   INT           NOT NULL AUTO_INCREMENT,
  person_name VARCHAR(1000) NOT NULL,
  PRIMARY KEY (person_id)
);

CREATE TABLE fruit (
  fruit_id    INT           NOT NULL AUTO_INCREMENT,
  fruit_name  VARCHAR(1000) NOT NULL,
  fruit_color VARCHAR(1000) NOT NULL,
  fruit_price INT           NOT NULL,
  PRIMARY KEY (fruit_id)
);

CREATE TABLE person_fruit (
  pf_id     INT NOT NULL AUTO_INCREMENT,
  pf_person INT NOT NULL,
  pf_fruit  INT NOT NULL,
  PRIMARY KEY (pf_id),
  FOREIGN KEY (pf_person) REFERENCES person (person_id),
  FOREIGN KEY (pf_fruit) REFERENCES fruit (fruit_id)
);

INSERT INTO person (person_name)
VALUES
  ('John'),
  ('Mary'),
  ('John'); -- again

INSERT INTO fruit (fruit_name, fruit_color, fruit_price)
VALUES
  ('apple', 'red', 1),
  ('orange', 'orange', 2),
  ('pineapple', 'yellow', 3);

INSERT INTO person_fruit (pf_person, pf_fruit)
VALUES
  (1, 1),
  (1, 2),
  (2, 2),
  (2, 3),
  (3, 1),
  (3, 2),
  (3, 3);

If you wish to associate the person with an array of fruits, you can do so with a view:

DROP VIEW IF EXISTS person_fruit_summary;
CREATE VIEW person_fruit_summary AS
  SELECT
    person_id                                                                                              AS pfs_person_id,
    max(person_name)                                                                                       AS pfs_person_name,
    cast(concat('[', group_concat(json_quote(fruit_name) ORDER BY fruit_name SEPARATOR ','), ']') as json) AS pfs_fruit_name_array
  FROM
    person
    INNER JOIN person_fruit
      ON person.person_id = person_fruit.pf_person
    INNER JOIN fruit
      ON person_fruit.pf_fruit = fruit.fruit_id
  GROUP BY
    person_id;

The view shows the following data:

+---------------+-----------------+----------------------------------+
| pfs_person_id | pfs_person_name | pfs_fruit_name_array             |
+---------------+-----------------+----------------------------------+
|             1 | John            | ["apple", "orange"]              |
|             2 | Mary            | ["orange", "pineapple"]          |
|             3 | John            | ["apple", "orange", "pineapple"] |
+---------------+-----------------+----------------------------------+

In 5.7.22, you'll want to use JSON_ARRAYAGG, rather than hack the array together from a string.

In this case a loop will also do the job (and is usually sufficiently fast).

a <- array(0, dim=dim(X))
for (i in 1:ncol(X)) {a[,i] <- X[,i]}

In my and other many vim users, the best option is to,

• Open the file using,

:e file_name.extension

And then just Ctrl + 6 to change to the last buffer. Or, you can always press

:ls to list the buffer and then change the buffer using b followed by the buffer number.

• We make a vertical or horizontal split using

:vsp for vertical split

:sp for horizantal split

And then <C-W><C-H/K/L/j> to change the working split.

You can ofcourse edit any file in any number of splits.

You can use Dialog to create this easily

create a Dialog instance using the context

Dialog dialog = new Dialog(contex);

You can design your layout as you like.

You can add this layout to your dialog by dialog.setContentView(R.layout.popupview);//popup view is the layout you created

then you can access its content (textviews, etc.) by using findViewById method

TextView txt = (TextView)dialog.findViewById(R.id.textbox);

you can add any text here. the text can be stored in the String.xml file in res\values.

txt.setText(getString(R.string.message));

then finally show the pop up menu

dialog.show();

What's the difference between Perl's backticks (`), system, and exec?

exec -> exec "command"; ,
system -> system("command"); and 
backticks -> print `command`;

exec

exec executes a command and never resumes the Perl script. It's to a script like a return statement is to a function.

If the command is not found, exec returns false. It never returns true, because if the command is found, it never returns at all. There is also no point in returning STDOUT, STDERR or exit status of the command. You can find documentation about it in perlfunc, because it is a function.

E.g.:

#!/usr/bin/perl
print "Need to start exec command";
my $data2 = exec('ls');
print "Now END exec command";
print "Hello $data2\n\n";

In above code, there are three print statements, but due to exec leaving the script, only the first print statement is executed. Also, the exec command output is not being assigned to any variable.

Here, only you're only getting the output of the first print statement and of executing the ls command on standard out.

system

system executes a command and your Perl script is resumed after the command has finished. The return value is the exit status of the command. You can find documentation about it in perlfunc.

E.g.:

#!/usr/bin/perl
print "Need to start system command";
my $data2 = system('ls');
print "Now END system command";
print "Hello $data2\n\n";

In above code, there are three print statements. As the script is resumed after the system command, all three print statements are executed.

Also, the result of running system is assigned to data2, but the assigned value is 0 (the exit code from ls).

Here, you're getting the output of the first print statement, then that of the ls command, followed by the outputs of the final two print statements on standard out.

backticks (`)

Like system, enclosing a command in backticks executes that command and your Perl script is resumed after the command has finished. In contrast to system, the return value is STDOUT of the command. qx// is equivalent to backticks. You can find documentation about it in perlop, because unlike system and exec, it is an operator.

E.g.:

#!/usr/bin/perl
print "Need to start backticks command";
my $data2 = `ls`;
print "Now END system command";
print "Hello $data2\n\n";

In above code, there are three print statements and all three are being executed. The output of ls is not going to standard out directly, but assigned to the variable data2 and then printed by the final print statement.

In a REST API, you shouldn't be overly concerned by predictable URI's. The very suggestion of URI predictability alludes to a misunderstanding of RESTful architecture. It assumes that a client should be constructing URIs themselves, which they really shouldn't have to.

However, I assume that you are not creating a true REST API, but a 'REST inspired' API (such as the Google Drive one). In these cases the rule of thumb is 'path params = resource identification' and 'query params = resource sorting'. So, the question becomes, can you uniquely identify your resource WITHOUT status / region? If yes, then perhaps its a query param. If no, then its a path param.

HTH.

There is one more way to run grunt on windows, without adding anything globally. This is a case when you don't have to do anything with %PATH%

if you have grunt and grunt-cli installed (without -g switch). Either by:

npm install grunt-cli
npm install [email protected]

Or by having that in your packages.json file like:

"devDependencies": {
    "grunt-cli": "^1.2.0",
    "grunt": "^0.4.5",

You can call grunt from your local installation by:

node node_modules\grunt-cli\bin\grunt --version

This is a solution for those who for some reasons don't want to or can't play with PATH, or have something else messing it all the time, for instance on a build agent.

Edit: Added versions as the grunt-cli works with grunt > 0.3

#input_box {
    margin: 0 auto;
    text-align: left;
}
#div {
    text-align: center;
}

<div id="div">
    <label for="input_box">Input: </label><input type="text" id="input_box" name="input_box" />
</div>

or you could do it using padding, but this is not that great of an idea.

Serialization:

// Convert an object to JSON string format
string jsonData = JsonConvert.SerializeObject(obj);

Response.Write(jsonData);

Deserialization::

To deserialize a dynamic object

  string json = @"{
      'Name': 'name',
      'Description': 'des'
    }";

var res = JsonConvert.DeserializeObject< dynamic>(json);

Response.Write(res.Name);

This is very similar to another stackoverflow article, Bind a function to Twitter Bootstrap Modal Close. Assuming you are using some version of Bootstap v3 or v4, you can do something like the following:

$("#myModal").on("hidden.bs.modal", function () {
    // put your default event here
});

Adding the following method to your repository should allow you to call $repo->getCourseCount() from your Controller.

/**
 * @return array
 */
public function getCourseCount()
{
    $qb = $this->getEntityManager()->createQueryBuilder();

    $qb
        ->select('count(course.id)')
        ->from('CRMPicco\Component\Course\Model\Course', 'course')
    ;

    $query = $qb->getQuery();

    return $query->getSingleScalarResult();
}
