Following Misko's advice, if you want async operation, then instead of $timeout() (which doesn't work)

$timeout(function () { $scope.assignmentsLoaded(data); }, 1000);

use $evalAsync() (which does work)

$scope.$evalAsync(function() { $scope.assignmentsLoaded(data); } );

Fiddle. I also added a "remove row of data" link that will modify $scope.assignments, simulating a change to the data/model -- to show that changing the data works.

The Runtime section of the Conceptual Overview page explains that evalAsync should be used when you need something to occur outside the current stack frame, but before the browser renders. (Guessing here... "current stack frame" probably includes Angular DOM updates.) Use $timeout if you need something to occur after the browser renders.

However, as you already found out, I don't think there is any need for async operation here.

I think it's best if you use methods with generic arguments, like the following :

public static void SerializeToXml<T>(T obj, string fileName)
{
    using (var fileStream = new FileStream(fileName, FileMode.Create))
    { 
        var ser = new XmlSerializer(typeof(T)); 
        ser.Serialize(fileStream, obj);
    }
}

public static T DeserializeFromXml<T>(string xml)
{
    T result;
    var ser = new XmlSerializer(typeof(T));
    using (var tr = new StringReader(xml))
    {
        result = (T)ser.Deserialize(tr);
    }
    return result;
}

Pass Data using NSNotificationCenter

You can also pass data using NotificationCentre in swift 3.0 and NSNotificationCenter in swift 2.0.

Swift 2.0 Version

Pass info using userInfo which is a optional Dictionary of type [NSObject : AnyObject]?

let imageDataDict:[String: UIImage] = ["image": image]

// Post a notification
 NSNotificationCenter.defaultCenter().postNotificationName(notificationName, object: nil, userInfo: imageDataDict)

// Register to receive notification in your class
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.showSpinningWheel(_:)), name: notificationName, object: nil)

// handle notification
func showSpinningWheel(notification: NSNotification) {
  if let image = notification.userInfo?["image"] as? UIImage {
  // do something with your image   
  }
}

Swift 3.0 Version

The userInfo now takes [AnyHashable:Any]? as an argument, which we provide as a dictionary literal in Swift

let imageDataDict:[String: UIImage] = ["image": image]

// post a notification
 NotificationCenter.default.post(name: NSNotification.Name(rawValue: "notificationName"), object: nil, userInfo: imageDataDict) 
// `default` is now a property, not a method call

// Register to receive notification in your class
NotificationCenter.default.addObserver(self, selector: #selector(self.showSpinningWheel(_:)), name: NSNotification.Name(rawValue: "notificationName"), object: nil)

// handle notification
func showSpinningWheel(_ notification: NSNotification) {

  if let image = notification.userInfo?["image"] as? UIImage {
  // do something with your image   
  }
}

Source pass data using NotificationCentre(swift 3.0) and NSNotificationCenter(swift 2.0)

You can't call "printf" with a std::string in parameter. The "%s" is designed for C-style string : char* or char []. In C++ you can do like that :

#include <iostream>
std::cout << YourString << std::endl;

If you absolutely want to use printf, you can use the "c_str()" method that give a char* representation of your string.

printf("%s\n",YourString.c_str())

Try this:

DELETE `deadline`
FROM `deadline`
INNER JOIN `job` ON `deadline`.`job_id` = `job`.`id`
WHERE `job`.`id` = 123

In Late September 2016, SciKit Learn 0.18 was released and there was a slight change to the code. With SciKit Learn 0.18 the train_test_split function is now imported from model_selection instead of cross_validation.

from sklearn.cross_validation import train_test_split

has been changed to :

from sklearn.model_selection import train_test_split

The same has also happened for GridSearchCV.

"How do I create an initial database ?"

You created a database when you installed XE. At some point the installation process prompted you to enter a password for the SYSTEM account. Use that to connect to the XE database using the SQL commandline on the application menu.

The XE documentation is online and pretty helpful. Find it here.

It's worth mentioning that 11g XE has several limitations, one of which is only one database per server. So using the pre-installed database is the sensible option.

• Deep copy: Clone this object and every reference to every other object it has
• Shallow copy: Clone this object and keep its references
• Object clone() throws CloneNotSupportedException: It is not specified whether this should return a deep or shallow copy, but at the very least: o.clone() != o

Hey I got something that seems to be doing what you want a do. It involves some dirty copying but works. You can find the working code here

So here is the main html file :

<!DOCTYPE html>
<html>
<head>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

    <script type="text/javascript">
        $(document).ready(function(){
            Iframe = $('#frame1');

            Iframe.on('load', function(){
                IframeInner = Iframe.contents().find('iframe');

                IframeInnerClone = IframeInner.clone();

                IframeInnerClone.insertAfter($('#insertIframeAfter')).css({display:'none'});

                IframeInnerClone.on('load', function(){
                    IframeContents = IframeInner.contents();

                    YourNestedEl = IframeContents.find('div');

                    $('<div>Yeepi! I can even insert stuff!</div>').insertAfter(YourNestedEl)
                });
            });
        });
    </script>
</head>
<body>
    <div id="insertIframeAfter">Hello!!!!</div>
    <iframe id="frame1" src="Test_Iframe.html">

    </iframe>
</body>
</html>

As you can see, once the first Iframe is loaded, I get the second one and clone it. I then reinsert it in the dom, so I can get access to the onload event. Once this one is loaded, I retrieve the content from non-cloned one (must have loaded as well, since they use the same src). You can then do wathever you want with the content.

Here is the Test_Iframe.html file :

<!DOCTYPE html>
<html>
<head>
</head>
<body>
    <div>Test_Iframe</div>
    <iframe src="Test_Iframe2.html">
    </iframe>
</body>
</html>

and the Test_Iframe2.html file :

<!DOCTYPE html>
<html>
<head>
</head>
<body>
    <div>I am the second nested iframe</div>
</body>
</html>

Two things which can be done more efficiently:

1. Use StringBuilder instead of StringBuffer since it's the faster and younger brother.
2. Use BufferedReader#readLine() to read it line by line instead of reading it char by char.

HttpResponse response; // some response object
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
StringBuilder builder = new StringBuilder();
for (String line = null; (line = reader.readLine()) != null;) {
    builder.append(line).append("\n");
}
JSONTokener tokener = new JSONTokener(builder.toString());
JSONArray finalResult = new JSONArray(tokener);

If the JSON is actually a single line, then you can also remove the loop and builder.

HttpResponse response; // some response object
BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
String json = reader.readLine();
JSONTokener tokener = new JSONTokener(json);
JSONArray finalResult = new JSONArray(tokener);

Apparently, all we need to do is:

1. Set all constraints to Scroll View (i.e. fix scroll view first)

2. Then set distance-from-scrollView constraint to the bottom most item to scroll view (which is the super view).

Note: Step 2 will tell storyboard where the last piece of content lies within Scroll view.

For those who are having trouble with fatal error: ESP8266WiFi.h: No such file or directory, you can install the package manually.

1. Download the Arduino ESP8266 core from here https://github.com/esp8266/Arduino
2. Go into library from the downloaded core and grab ESP8266WiFi.
3. Drag that into your local Arduino/library folder. This can be found by going into preferences and looking at your Sketchbook location

You may still need to have the http://arduino.esp8266.com/stable/package_esp8266com_index.json package installed beforehand, however.

Edit: That wasn't the full issue, you need to make sure you have the correct ESP8266 Board selected before compiling.

Hope this helps others.

Since WooCommerce 2.2 you are able to simply use the wc_get_product Method. As an argument you can pass the ID or simply leave it empty if you're already in the loop.

wc_get_product()->get_id();

OR with 2 lines

$product = wc_get_product();
$id = $product->get_id();

Calling a generic method with a type parameter known only at runtime can be greatly simplified by using a dynamic type instead of the reflection API.

To use this technique the type must be known from the actual object (not just an instance of the Type class). Otherwise, you have to create an object of that type or use the standard reflection API solution. You can create an object by using the Activator.CreateInstance method.

If you want to call a generic method, that in "normal" usage would have had its type inferred, then it simply comes to casting the object of unknown type to dynamic. Here's an example:

class Alpha { }
class Beta { }
class Service
{
    public void Process<T>(T item)
    {
        Console.WriteLine("item.GetType(): " + item.GetType()
                          + "\ttypeof(T): " + typeof(T));
    }
}

class Program
{
    static void Main(string[] args)
    {
        var a = new Alpha();
        var b = new Beta();

        var service = new Service();
        service.Process(a); // Same as "service.Process<Alpha>(a)"
        service.Process(b); // Same as "service.Process<Beta>(b)"

        var objects = new object[] { a, b };
        foreach (var o in objects)
        {
            service.Process(o); // Same as "service.Process<object>(o)"
        }
        foreach (var o in objects)
        {
            dynamic dynObj = o;
            service.Process(dynObj); // Or write "service.Process((dynamic)o)"
        }
    }
}

And here's the output of this program:

item.GetType(): Alpha    typeof(T): Alpha
item.GetType(): Beta     typeof(T): Beta
item.GetType(): Alpha    typeof(T): System.Object
item.GetType(): Beta     typeof(T): System.Object
item.GetType(): Alpha    typeof(T): Alpha
item.GetType(): Beta     typeof(T): Beta

Process is a generic instance method that writes the real type of the passed argument (by using the GetType() method) and the type of the generic parameter (by using typeof operator).

By casting the object argument to dynamic type we deferred providing the type parameter until runtime. When the Process method is called with the dynamic argument then the compiler doesn't care about the type of this argument. The compiler generates code that at runtime checks the real types of passed arguments (by using reflection) and choose the best method to call. Here there is only this one generic method, so it's invoked with a proper type parameter.

In this example, the output is the same as if you wrote:

foreach (var o in objects)
{
    MethodInfo method = typeof(Service).GetMethod("Process");
    MethodInfo generic = method.MakeGenericMethod(o.GetType());
    generic.Invoke(service, new object[] { o });
}

The version with a dynamic type is definitely shorter and easier to write. You also shouldn't worry about performance of calling this function multiple times. The next call with arguments of the same type should be faster thanks to the caching mechanism in DLR. Of course, you can write code that cache invoked delegates, but by using the dynamic type you get this behaviour for free.

If the generic method you want to call don't have an argument of a parametrized type (so its type parameter can't be inferred) then you can wrap the invocation of the generic method in a helper method like in the following example:

class Program
{
    static void Main(string[] args)
    {
        object obj = new Alpha();

        Helper((dynamic)obj);
    }

    public static void Helper<T>(T obj)
    {
        GenericMethod<T>();
    }

    public static void GenericMethod<T>()
    {
        Console.WriteLine("GenericMethod<" + typeof(T) + ">");
    }
}

Increased type safety

What is really great about using dynamic object as a replacement for using reflection API is that you only lose compile time checking of this particular type that you don't know until runtime. Other arguments and the name of the method are staticly analysed by the compiler as usual. If you remove or add more arguments, change their types or rename method name then you'll get a compile-time error. This won't happen if you provide the method name as a string in Type.GetMethod and arguments as the objects array in MethodInfo.Invoke.

Below is a simple example that illustrates how some errors can be caught at compile time (commented code) and other at runtime. It also shows how the DLR tries to resolve which method to call.

interface IItem { }
class FooItem : IItem { }
class BarItem : IItem { }
class Alpha { }

class Program
{
    static void Main(string[] args)
    {
        var objects = new object[] { new FooItem(), new BarItem(), new Alpha() };
        for (int i = 0; i < objects.Length; i++)
        {
            ProcessItem((dynamic)objects[i], "test" + i, i);

            //ProcesItm((dynamic)objects[i], "test" + i, i);
            //compiler error: The name 'ProcesItm' does not
            //exist in the current context

            //ProcessItem((dynamic)objects[i], "test" + i);
            //error: No overload for method 'ProcessItem' takes 2 arguments
        }
    }

    static string ProcessItem<T>(T item, string text, int number)
        where T : IItem
    {
        Console.WriteLine("Generic ProcessItem<{0}>, text {1}, number:{2}",
                          typeof(T), text, number);
        return "OK";
    }
    static void ProcessItem(BarItem item, string text, int number)
    {
        Console.WriteLine("ProcessItem with Bar, " + text + ", " + number);
    }
}

Here we again execute some method by casting the argument to the dynamic type. Only verification of first argument's type is postponed to runtime. You will get a compiler error if the name of the method you're calling doesn't exist or if other arguments are invalid (wrong number of arguments or wrong types).

When you pass the dynamic argument to a method then this call is lately bound. Method overload resolution happens at runtime and tries to choose the best overload. So if you invoke the ProcessItem method with an object of BarItem type then you'll actually call the non-generic method, because it is a better match for this type. However, you'll get a runtime error when you pass an argument of the Alpha type because there's no method that can handle this object (a generic method has the constraint where T : IItem and Alpha class doesn't implement this interface). But that's the whole point. The compiler doesn't have information that this call is valid. You as a programmer know this, and you should make sure that this code runs without errors.

Return type gotcha

When you're calling a non-void method with a parameter of dynamic type, its return type will probably be dynamic too. So if you'd change previous example to this code:

var result = ProcessItem((dynamic)testObjects[i], "test" + i, i);

then the type of the result object would be dynamic. This is because the compiler don't always know which method will be called. If you know the return type of the function call then you should implicitly convert it to the required type so the rest of the code is statically typed:

string result = ProcessItem((dynamic)testObjects[i], "test" + i, i);

You'll get a runtime error if the type doesn't match.

Actually, if you try to get the result value in the previous example then you'll get a runtime error in the second loop iteration. This is because you tried to save the return value of a void function.

Your function would work like this:

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS 
$$
BEGIN

RETURN QUERY EXECUTE '
WITH v_tb_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;

END     
$$ LANGUAGE plpgsql;

Call:

SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)

• You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.

• The aggregate function count() returns bigint, but you had rowcount defined as integer, so you need an explicit cast ::int to make this work

• I use dollar quoting to avoid quoting hell.

However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.

Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)

The query itself seems rather odd, btw. But that's beside the point here.

a little late here but this should help. create this class(its written in typescript but its easy to convert it to javascript)

export class debouncedMethod<T>{
  constructor(method:T, debounceTime:number){
    this._method = method;
    this._debounceTime = debounceTime;
  }
  private _method:T;
  private _timeout:number;
  private _debounceTime:number;
  public invoke:T = ((...args:any[])=>{
    this._timeout && window.clearTimeout(this._timeout);
    this._timeout = window.setTimeout(()=>{
      (this._method as any)(...args);
    },this._debounceTime);
  }) as any;
}

and to use

var foo = new debouncedMethod((name,age)=>{
 console.log(name,age);
},500);
foo.invoke("john",31);

Best practice of getting length is use length filter returns the number of items of a sequence or mapping, or the length of a string. For example: {{ notcount | length }}

But you can calculate count of elements in for loop. For example:

{% set count = 0 %}
{% for nc in notcount %}
    {% set count = count + 1 %}
{% endfor %}

{{ count }}

This solution helps if you want to calculate count of elements by condition, for example you have a property name inside object and you want to calculate count of objects with not empty names:

{% set countNotEmpty = 0 %}
{% for nc in notcount if nc.name %}
    {% set countNotEmpty = countNotEmpty + 1 %}
{% endfor %}

{{ countNotEmpty }}

You could simply use .rounded-circle bootstrap.

 <img class="rounded-circle" src="http://placekitten.com/g/200/200"/>

You can even specify the width and height of the rounded image by providing an inline style to the image, which overrides the default size.

 <img class="rounded-circle" style="height:100px; width: 100px" src="http://placekitten.com/g/200/200" />

Git reset has 5 main modes: soft, mixed, merged, hard, keep. The difference between them is to change or not change head, stage (index), working directory.

Git reset --hard will change head, index and working directory.
Git reset --soft will change head only. No change to index, working directory.

So in other words if you want to undo your commit, --soft should be good enough. But after that you still have the changes from bad commit in your index and working directory. You can modify the files, fix them, add them to index and commit again.

With the --hard, you completely get a clean slate in your project. As if there hasn't been any change from the last commit. If you are sure this is what you want then move forward. But once you do this, you'll lose your last commit completely. (Note: there are still ways to recover the lost commit).

You can use strtotime() for time calculation. Here is an example:

$checkTime = strtotime('09:00:59');
echo 'Check Time : '.date('H:i:s', $checkTime);
echo '<hr>';

$loginTime = strtotime('09:01:00');
$diff = $checkTime - $loginTime;
echo 'Login Time : '.date('H:i:s', $loginTime).'<br>';
echo ($diff < 0)? 'Late!' : 'Right time!'; echo '<br>';
echo 'Time diff in sec: '.abs($diff);

echo '<hr>';

$loginTime = strtotime('09:00:59');
$diff = $checkTime - $loginTime;
echo 'Login Time : '.date('H:i:s', $loginTime).'<br>';
echo ($diff < 0)? 'Late!' : 'Right time!';

echo '<hr>';

$loginTime = strtotime('09:00:00');
$diff = $checkTime - $loginTime;
echo 'Login Time : '.date('H:i:s', $loginTime).'<br>';
echo ($diff < 0)? 'Late!' : 'Right time!';

Check the already-asked question - how to get time difference in minutes:

If you don't want to retain the ordering of ids, then you can

ALTER SEQUENCE seq RESTART WITH 1;
UPDATE t SET idcolumn=nextval('seq');

I doubt there's an easy way to do that in the order of your choice without recreating the whole table.

And for comedic value:

label.text = [NSString stringWithFormat:@"%@", [NSNumber numberWithInt:count]];

(Though it could be useful if one day you're dealing with NSNumber's)

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

And then install wget with brew and also enable openressl for TLS support

brew install wget --with-libressl

It worked perfectly for me.

To add all file at a time, use git add -A

I used it successfully in a personal project to identify the letter from an image such as this, you can find all the source for the OCR component of my application on github, here.

I noticed that the answers here are using: device-width, device-height, min-device-width, min-device-height, max-device-width, max-device-height.

Please refrain from using them since they are deprecated. see MDN for reference. Instead use the regular min-width, max-width and so on. For extra assurance, you can set the min and max to the same px amount. For example:

iPhone X

@media only screen 
    and (width : 375px) 
    and (height : 635px)
    and (orientation : portrait)  
    and (-webkit-device-pixel-ratio : 3) { }

You may also notice that I am using 635px for height. Try it yourself the window height is actually 635px. run iOS simulator for iPhone X and in Safari Web inspector do window.innerHeight. Here are a few useful links on this subject:

The JDK 1.6 provides the java.text.Normalizer class that can be used for this task.

See an example here

I add custom commands to a environment evoked in a CMD after starting services... I haven't done it with postgres, but with Oracle:

#set up var with noop command
RUN export POST_START_CMDS=":"
RUN mkdir /scripts
ADD script.sql /scripts
CMD service oracle-xe start; $POST_START_CMDS; tail -f /var/log/dmesg

and start with

docker run -d ... -e POST_START_CMDS="su - oracle -c 'sqlplus @/scripts/script' " <image>

.

This code is from Processing.org an open source Java based IDE. You can find it Processing.org. The Arduino IDE also uses this extension, although they run on a hardware board.

EDIT - And yes it is C syntax, used mostly for art or live media presentations.

This question seems to be ambiguous.

I'll try with my interpretation of the request.

def do_something(data)
   puts "Found! #{data}"
end

a = { 'x' => 'test', 'y' => 'foo', 'z' => 'bar' }
a.each { |key,value| do_something(value) if key == 'x' }

This will loop over all the key,value pairs and do something only if the key is 'x'.

Ok, Denizens. So I have accepted the command line length limits as gospel for quite some time. So, what to do with one's assumptions? Naturally- check them.

I have a Fedora 22 machine at my disposal (meaning: Linux with bash4). I have created a directory with 500,000 inodes (files) in it each of 18 characters long. The command line length is 9,500,000 characters. Created thus:

seq 1 500000 | while read digit; do
    touch $(printf "abigfilename%06d\n" $digit);
done

And we note:

$ getconf ARG_MAX
2097152

Note however I can do this:

$ echo * > /dev/null

But this fails:

$ /bin/echo * > /dev/null
bash: /bin/echo: Argument list too long

I can run a for loop:

$ for f in *; do :; done

which is another shell builtin.

Careful reading of the documentation for ARG_MAX states, Maximum length of argument to the exec functions. This means: Without calling exec, there is no ARG_MAX limitation. So it would explain why shell builtins are not restricted by ARG_MAX.

And indeed, I can ls my directory if my argument list is 109948 files long, or about 2,089,000 characters (give or take). Once I add one more 18-character filename file, though, then I get an Argument list too long error. So ARG_MAX is working as advertised: the exec is failing with more than ARG_MAX characters on the argument list- including, it should be noted, the environment data.

select 'abcd' + ltrim(str(1)) + ltrim(str(2))

Here is an example that lists all the files on my desktop. you should change the path variable to your path.

Instead of printing the file's name with System.out.println, you should place your own code to operate on the file.

public static void main(String[] args) {
    File path = new File("c:/documents and settings/Zachary/desktop");

    File [] files = path.listFiles();
    for (int i = 0; i < files.length; i++){
        if (files[i].isFile()){ //this line weeds out other directories/folders
            System.out.println(files[i]);
        }
    }
}

Outline is good, but only when you want the border all around.

Lets say if you want to make it only on bottom or top you can use

<style>

  #border-top {
  border-top: 1px solid  #ccc;
  box-shadow: inset 0 1px 0 #fff;
}
</style>

<p id="border-top">This is my content</p>

And for bottom:

<style>

      #border-bottom {
      border-top: 1px solid  #ccc;
      box-shadow: 0 1px 0 #fff;
    }
</style>

    <p id="border-bottom">This is my content</p>

Hope that this helps.

for swift4 code, first enable editing:

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
    return true
}

then you add delete action to the edit delegate:

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let action = UITableViewRowAction(style: .destructive, title: "Delete") { (_, index) in
        // delete model object at the index
        self.models[index.row]
        // then delete the cell
        tableView.beginUpdates()
        tableView.deleteRows(at: [index], with: .automatic)
        tableView.endUpdates()

    }
    return [action]
}

A couple of gotchas that are colloraries to Andrew Shelansky's excellent answer and to disagree a little with doesn't really change the way that the compiler reads the code

Because your function prototypes are compiled as C, you can't have overloading of the same function names with different parameters - that's one of the key features of the name mangling of the compiler. It is described as a linkage issue but that is not quite true - you will get errors from both the compiler and the linker.

The compiler errors will be if you try to use C++ features of prototype declaration such as overloading.

The linker errors will occur later because your function will appear to not be found, if you do not have the extern "C" wrapper around declarations and the header is included in a mixture of C and C++ source.

One reason to discourage people from using the compile C as C++ setting is because this means their source code is no longer portable. That setting is a project setting and so if a .c file is dropped into another project, it will not be compiled as c++. I would rather people take the time to rename file suffixes to .cpp.

David had the right answer. The parenthesis () makes it so that the callable timezone.now() is called every time the model is evaluated. If you remove the () from timezone.now() (or datetime.now(), if using the naive datetime object) to make it just this:

default=timezone.now

Then it will work as you expect:
New objects will receive the current date when they are created, but the date won't be overridden every time you do manage.py makemigrations/migrate.

I just encountered this. Much thanks to David.

I had similar problem. I needed to write down csv file on driver while I was connect to cluster in client mode.

I wanted to reuse the same CSV parsing code as Apache Spark to avoid potential errors.

I checked spark-csv code and found code responsible for converting dataframe into raw csv RDD[String] in com.databricks.spark.csv.CsvSchemaRDD.

Sadly it is hardcoded with sc.textFile and the end of relevant method.

I copy-pasted that code and removed last lines with sc.textFile and returned RDD directly instead.

My code:

/*
  This is copypasta from com.databricks.spark.csv.CsvSchemaRDD
  Spark's code has perfect method converting Dataframe -> raw csv RDD[String]
  But in last lines of that method it's hardcoded against writing as text file -
  for our case we need RDD.
 */
object DataframeToRawCsvRDD {

  val defaultCsvFormat = com.databricks.spark.csv.defaultCsvFormat

  def apply(dataFrame: DataFrame, parameters: Map[String, String] = Map())
           (implicit ctx: ExecutionContext): RDD[String] = {
    val delimiter = parameters.getOrElse("delimiter", ",")
    val delimiterChar = if (delimiter.length == 1) {
      delimiter.charAt(0)
    } else {
      throw new Exception("Delimiter cannot be more than one character.")
    }

    val escape = parameters.getOrElse("escape", null)
    val escapeChar: Character = if (escape == null) {
      null
    } else if (escape.length == 1) {
      escape.charAt(0)
    } else {
      throw new Exception("Escape character cannot be more than one character.")
    }

    val quote = parameters.getOrElse("quote", "\"")
    val quoteChar: Character = if (quote == null) {
      null
    } else if (quote.length == 1) {
      quote.charAt(0)
    } else {
      throw new Exception("Quotation cannot be more than one character.")
    }

    val quoteModeString = parameters.getOrElse("quoteMode", "MINIMAL")
    val quoteMode: QuoteMode = if (quoteModeString == null) {
      null
    } else {
      QuoteMode.valueOf(quoteModeString.toUpperCase)
    }

    val nullValue = parameters.getOrElse("nullValue", "null")

    val csvFormat = defaultCsvFormat
      .withDelimiter(delimiterChar)
      .withQuote(quoteChar)
      .withEscape(escapeChar)
      .withQuoteMode(quoteMode)
      .withSkipHeaderRecord(false)
      .withNullString(nullValue)

    val generateHeader = parameters.getOrElse("header", "false").toBoolean
    val headerRdd = if (generateHeader) {
      ctx.sparkContext.parallelize(Seq(
        csvFormat.format(dataFrame.columns.map(_.asInstanceOf[AnyRef]): _*)
      ))
    } else {
      ctx.sparkContext.emptyRDD[String]
    }

    val rowsRdd = dataFrame.rdd.map(row => {
      csvFormat.format(row.toSeq.map(_.asInstanceOf[AnyRef]): _*)
    })

    headerRdd union rowsRdd
  }

}

To capture several parameters using the same name, I modified the while loop in Tomalak's method like this:

  while (match = re.exec(url)) {
    var pName = decode(match[1]);
    var pValue = decode(match[2]);
    params[pName] ? params[pName].push(pValue) : params[pName] = [pValue];
  }

input: ?firstname=george&lastname=bush&firstname=bill&lastname=clinton

returns: {firstname : ["george", "bill"], lastname : ["bush", "clinton"]}

You can be explicit about the joins:

SELECT Table1.Col1, Table1.Col2, Table1.Col3, Table2.Col4
FROM Table1 INNER JOIN
     Table2
      ON (Table1.Col1 = Table2.Col1 or Table1.Col1 is NULL and Table2.Col1 is NULL) AND
         (Table1.Col2 = Table2.Col2 or Table1.Col2 is NULL and Table2.Col2 is NULL)

In practice, I would be more likely to use coalesce() in the join condition:

SELECT Table1.Col1, Table1.Col2, Table1.Col3, Table2.Col4
FROM Table1 INNER JOIN
     Table2
     ON (coalesce(Table1.Col1, '') = coalesce(Table2.Col1, '')) AND
        (coalesce(Table1.Col2, '') = coalesce(Table2.Col2, ''))

Where '' would be a value not in either of the tables.

Just a word of caution. In most databases, using any of these constructs prevents the use of indexes.

I managed to find the solution that will allow you to do this using default confirm() with minimum of changes if you have a lot of confirm() actions through out you code. This example uses jQuery and Bootstrap but the same thing can be accomplished using other libraries as well. You can just copy paste this and it should work right away

There is a difference between signed and unsigned APK files. Most likely you had an unsigned on there previously. You just need to delete the unsigned before you install the signed version. How this can be accomplished varies on the exact version, but in general, go on the emulator to settings-> application, long click your app, and delete/remove/uninstall it.

Replace These Headers

#include <iomanip.h>
#include <iomanip>

With These.

#include <iostream>
#include <iomanip>
using namespace std;

Thats it...!!!

Add the css:

   html,body{
        height:100%;
        }
    .bg-img {
        background: url(image.jpg) no-repeat center top; 
        background-size: cover; 
        height:100%;     
    }

And html is:

<div class="bg-mg"></div>

CSS: stretching background image to 100% width and height of screen?

When you set a string variable, it doesn't save quotes of it, they are a part of its definition. so you don't need to use :1

I had a similar issue and found out that if you have a class that contains transitions, the element will blink. I tried to add ng-cloak without success, but by removing the transition the button stopped blinking.

I'm using ionic framework and the button-outline has this transition

.button-outline {
  -webkit-transition: opacity .1s;
  transition: opacity .1s;
}

Simply overwrite the class to remove the transition and the button will stop blinking.

Update

Again on ionic there is a flicker when using ng-show/ng-hide. Adding the following CSS resolves it:

.ng-hide-add,
.ng-hide-remove {
  display: none !important;
}

Source: http://forum.ionicframework.com/t/beta-14-ng-hide-show/14270/9

    this.state.user.isLoggedIn ? 
    (<Dashboard authenticate={this.authenticate} user={this.state.user} />) : 
    (<Redirect to="/login" />)
)} />

authenticate props will be passed to components e.g. signup using which user state can be changed. Complete AppRoutes-

import React from 'react';

import Home from '../pages/home';

import Dashboard from '../pages/dashboard';

import { config } from '../utils/Config';

export default class AppRoutes extends React.Component {

    constructor(props) {
        super(props);

        // initially assuming that user is logged out
        let user = {
            isLoggedIn: false
        }

        // if user is logged in, his details can be found from local storage
        try {
            let userJsonString = localStorage.getItem(config.localStorageKey);
            if (userJsonString) {
                user = JSON.parse(userJsonString);
            }
        } catch (exception) {

I am getting a very simple solution to set ActionBar Title in either fragment or any activity without any headache.

Just modify the xml where is defined Toolbar as below :

<android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@color/colorPrimaryDark"
            app:popupTheme="@style/AppTheme.PopupOverlay" >

            <TextView
                style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
                android:id="@+id/toolbar_title"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="@string/app_name"
                />
            </android.support.v7.widget.Toolbar>

    </android.support.design.widget.AppBarLayout> 

1) If you want to set the actionbar in a fragment then :

Toolbar toolbar = findViewById(R.id.toolbar);
TextView toolbarTitle = (TextView) toolbar.findViewById(R.id.toolbar_title);

For using it from anywhere, you can define a method in the activity

public void setActionBarTitle(String title) {
        toolbarTitle.setText(title);
    }

To call this method in activity, simply call it.

setActionBarTitle("Your Title")

To call this method from fragment of the activity, simply call it.

I found this article enormously helpful. Huge thanks to yonran. I wanted to pass on some additional learning I found while implementing some of the techniques he provided. In FF6 and Chrome 9, support for media queries from JS was added, which can greatly simplify the media query approach necessary for determining zoom in FF. See the docs at MDN here. For my purposes, I only needed to detect whether the browser was zoomed in or out, I had no need for the actual zoom factor. I was able to get my answer with one line of JavaScript:

var isZoomed = window.matchMedia('(max--moz-device-pixel-ratio:0.99), (min--moz-device-pixel-ratio:1.01)').matches;

Combining this with the IE8+ and Webkit solutions, which were also single lines, I was able to detect zoom on the vast majority of browsers hitting our app with only a few lines of code.

So you want the next multiple of 6, is that it?

You can divide your number by 6, then ceil it, and multiply it again:

$answer = ceil($foo / 6) * 6;

You can find it here: RTL Bootstrap v3.2.0.

Like everyone else:

for i, val in enumerate(data):
    print i, val

but also

for i, val in enumerate(data, 1):
    print i, val

In other words, you can specify as starting value for the index/count generated by enumerate() which comes in handy if you don't want your index to start with the default value of zero.

I was printing out lines in a file the other day and specified the starting value as 1 for enumerate(), which made more sense than 0 when displaying information about a specific line to the user.

Selectors work only for drawables, not styles. Reference

First, to make the button background transparent use the following attribute as this will not affect the material design animations:

style="?attr/buttonBarButtonStyle"

There are many ways to style your button. Check out this tutorial.

Second, to make the text bold on pressed, use this java code:

btn.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {

        switch (event.getAction()) {
            // When the user clicks the Button
            case MotionEvent.ACTION_DOWN:
                btn.setTypeface(Typeface.DEFAULT_BOLD);
                break;

            // When the user releases the Button
            case MotionEvent.ACTION_UP:
                btn.setTypeface(Typeface.DEFAULT);
                break;
        }
        return false;
    }
});

Several things:

Age is not an integer - it is a nullable integer type. They are not the same. See the documentation for Nullable<T> on MSDN for details.

?? is the null coalesce operator, not the ternary operator (actually called the conditional operator).

To check if a nullable type has a value use HasValue, or check directly against null:

if(Age.HasValue)
{
   // Yay, it does!
}

if(Age == null)
{
   // It is null :(
}

from the command line: for /R /D %1 in (*) do rd "%1"

in a batch file for /R /D %%1 in (*) do rd "%%1"

I don't know if it's documented as such, but it works in W2K, XP, and Win 7. And I don't know if it will always work, but it won't ever delete files by accident.

sleep doesn't work because the display can only be updated after your main thread returns to the system. NSTimer is the way to go. To do this, you need to implement methods which will be called by the timer to change the buttons. An example:

- (void)button_circleBusy:(id)sender {
    firstButton.enabled = NO;
    // 60 milliseconds is .06 seconds
    [NSTimer scheduledTimerWithTimeInterval:.06 target:self selector:@selector(goToSecondButton:) userInfo:nil repeats:NO];
}
- (void)goToSecondButton:(id)sender {
    firstButton.enabled = YES;
    secondButton.enabled = NO;
    [NSTimer scheduledTimerWithTimeInterval:.06 target:self selector:@selector(goToThirdButton:) userInfo:nil repeats:NO];
}
...

For both SQL Server and SQLite Databases, use:

_sqlServerDBsContext = new SqlServerDBsContext(new DbContextOptionsBuilder<SqlServerDBsContext>().UseSqlServer("Connection String to SQL DB").Options);

For SQLite, make sure Microsoft.EntityFrameworkCore.Sqlite is installed, then the connection string is simply "'DataSource='+ the file name".

_sqliteDBsContext = new SqliteDBsContext(new DbContextOptionsBuilder<SqliteDBsContext>().UseSqlite("Connection String to SQLite DB").Options);

use [[NSDate date] timeIntervalSince1970]

One very important use-case I just stumbled across: dict.setdefault() is great for multi-threaded code when you only want a single canonical object (as opposed to multiple objects that happen to be equal).

For example, the (Int)Flag Enum in Python 3.6.0 has a bug: if multiple threads are competing for a composite (Int)Flag member, there may end up being more than one:

from enum import IntFlag, auto
import threading

class TestFlag(IntFlag):
    one = auto()
    two = auto()
    three = auto()
    four = auto()
    five = auto()
    six = auto()
    seven = auto()
    eight = auto()

    def __eq__(self, other):
        return self is other

    def __hash__(self):
        return hash(self.value)

seen = set()

class cycle_enum(threading.Thread):
    def run(self):
        for i in range(256):
            seen.add(TestFlag(i))

threads = []
for i in range(8):
    threads.append(cycle_enum())

for t in threads:
    t.start()

for t in threads:
    t.join()

len(seen)
# 272  (should be 256)

The solution is to use setdefault() as the last step of saving the computed composite member -- if another has already been saved then it is used instead of the new one, guaranteeing unique Enum members.

There is no way to skip a check if it exists.

tar -cjf site1.tar.bz2 -C /var/www/site1 .

In the above example, tar will change to directory /var/www/site1 before doing its thing because the option -C /var/www/site1 was given.

From man tar:

OTHER OPTIONS

  -C, --directory DIR
       change to directory DIR

A prime number is any number that is only divisible by 1 and itself. All other numbers are called composite.

The simplest way, of finding a prime number, is to check if the input number is a composite number:

    function isPrime(number) {
        // Check if a number is composite
        for (let i = 2; i < number; i++) {
            if (number % i === 0) {
                return false;
            }
        }
        // Return true for prime numbers
        return true;
    }

The program has to divide the value of number by all the whole numbers from 1 and up to the its value. If this number can be divided evenly not only by one and itself it is a composite number.

The initial value of the variable i has to be 2 because both prime and composite numbers can be evenly divided by 1.

    for (let i = 2; i < number; i++)

Then i is less than number for the same reason. Both prime and composite numbers can be evenly divided by themselves. Therefore there is no reason to check it.

Then we check whether the variable can be divided evenly by using the remainder operator.

    if (number % i === 0) {
        return false;
    }

If the remainder is zero it means that number can be divided evenly, hence being a composite number and returning false.

If the entered number didn't meet the condition, it means it's a prime number and the function returns true.

This should work:

var hv = $('#h_v').val();
alert(hv);

Use the setState function. So you could do

       this.setState({this.state.foo.bar:123}) 

inside the handle event method.

Once, the state is updated, it will trigger changes, and re-render will take place.

You can use SRV records:

_service._proto.name. TTL class SRV priority weight port target.

Service: the symbolic name of the desired service.

Proto: the transport protocol of the desired service; this is usually either TCP or UDP.

Name: the domain name for which this record is valid, ending in a dot.

TTL: standard DNS time to live field.

Class: standard DNS class field (this is always IN).

Priority: the priority of the target host, lower value means more preferred.

Weight: A relative weight for records with the same priority.

Port: the TCP or UDP port on which the service is to be found.

Target: the canonical hostname of the machine providing the service, ending in a dot.

Example:

_sip._tcp.example.com. 86400 IN SRV 0 5 5060 sipserver.example.com.

So what I think you're looking for is to add something like this to your DNS hosts file:

_sip._tcp.arboristal.com. 86400 IN SRV 10 40 25565 mc.arboristal.com.
_sip._tcp.arboristal.com. 86400 IN SRV 10 30 25566 tekkit.arboristal.com.
_sip._tcp.arboristal.com. 86400 IN SRV 10 30 25567 pvp.arboristal.com.

On a side note, I highly recommend you go with a hosting company rather than hosting the servers yourself. It's just asking for trouble with your home connection (DDoS and Bandwidth/Connection Speed), but it's up to you.

Approaches 1 and 2 obviously don't work, because you get java.sql.Date objects, per JPA/Hibernate spec, and not java.util.Date. From approaches 3 and 4, I would rather choose the latter one, because it's more declarative, and will work with both field and getter annotations.

You have already laid out the solution 4 in your referenced blog post, as @tscho was kind to point out. Maybe defaultForType (see below) should give you the centralized solution you were looking for. Of course will will still need to differentiate between date (without time) and timestamp fields.

For future reference I will leave the summary of using your own Hibernate UserType here:

To make Hibernate give you java.util.Date instances, you can use the @Type and @TypeDef annotations to define a different mapping of your java.util.Date java types to and from the database.

See the examples in the core reference manual here.

1. Implement a UserType to do the actual plumbing (conversion to/from java.util.Date), named e.g. TimestampAsJavaUtilDateType

2. Add a @TypeDef annotation on one entity or in a package-info.java - both will be available globally for the session factory (see manual link above). You can use defaultForType to apply the type conversion on all mapped fields of type java.util.Date.

   @TypeDef
     name = "timestampAsJavaUtilDate",
     defaultForType = java.util.Date.class, /* applied globally */
     typeClass = TimestampAsJavaUtilDateType.class
   )
   

3. Optionally, instead of defaultForType, you can annotate your fields/getters with @Type individually:

   @Entity
   public class MyEntity {
      [...]
      @Type(type="timestampAsJavaUtilDate")
      private java.util.Date myDate;
      [...]
   }
   

P.S. To suggest a totally different approach: we usually just don't compare Date objects using equals() anyway. Instead we use a utility class with methods to compare e.g. only the calendar date of two Date instances (or another resolution such as seconds), regardless of the exact implementation type. That as worked well for us.

I'm too having problems with breakpoints in application_start with IIS a hosted app. A good workaround is using Debugger.Break(); in code instead of the VS breakpoint

{{convertToDate  | date :  dateformat}}                                             
$rootScope.dateFormat = 'MM/dd/yyyy';

The code below gives the HEX and RGB value of the range whether formatted using conditional formatting or otherwise. If the range is not formatted using Conditional Formatting and you intend to use iColor function in the Excel as UDF. It won't work. Read the below excerpt from MSDN.

Note that the DisplayFormat property does not work in user defined functions. For example, in a worksheet function that returns the interior color of a cell, if you use a line similar to:

Range.DisplayFormat.Interior.ColorIndex

then the worksheet function executes to return a #VALUE! error. If you are not finding color of the conditionally formatted range, then I encourage you to rather use

Range.Interior.ColorIndex

as then the function can also be used as UDF in Excel. Such as iColor(B1,"HEX")

Public Function iColor(rng As Range, Optional formatType As String) As Variant
'formatType: Hex for #RRGGBB, RGB for (R, G, B) and IDX for VBA Color Index
    Dim colorVal As Variant
    colorVal = rng.DisplayFormat.Interior.Color
    Select Case UCase(formatType)
        Case "HEX"
            iColor = "#" & Format(Hex(colorVal Mod 256),"00") & _
                           Format(Hex((colorVal \ 256) Mod 256),"00") & _
                           Format(Hex((colorVal \ 65536)),"00")
        Case "RGB"
            iColor = Format((colorVal Mod 256),"00") & ", " & _
                     Format(((colorVal \ 256) Mod 256),"00") & ", " & _
                     Format((colorVal \ 65536),"00")
        Case "IDX"
            iColor = rng.Interior.ColorIndex
        Case Else
            iColor = colorVal
    End Select
End Function

'Example use of the iColor function
Sub Get_Color_Format()
    Dim rng As Range

    For Each rng In Selection.Cells
        rng.Offset(0, 1).Value = iColor(rng, "HEX")
        rng.Offset(0, 2).Value = iColor(rng, "RGB")
    Next
End Sub

Importing it only for this reason might be overkill, but if you happen to be using pandas anyway, then the solution is simple and straightforward:

import pandas as pd
stuff = pd.Series(['a','b','a','c','a','d'])
less_stuff = stuff[stuff != 'a']  # define any condition here
# results ['b','c','d']

The following approach is similar to a2800276's, but with some C99 macro magic added:

// we need `size_t`
#include <stddef.h>

// argument types to accept
enum sum_arg_types { SUM_LONG, SUM_ULONG, SUM_DOUBLE };

// a structure to hold an argument
struct sum_arg
{
    enum sum_arg_types type;
    union
    {
        long as_long;
        unsigned long as_ulong;
        double as_double;
    } value;
};

// determine an array's size
#define count(ARRAY) ((sizeof (ARRAY))/(sizeof *(ARRAY)))

// this is how our function will be called
#define sum(...) _sum(count(sum_args(__VA_ARGS__)), sum_args(__VA_ARGS__))

// create an array of `struct sum_arg`
#define sum_args(...) ((struct sum_arg []){ __VA_ARGS__ })

// create initializers for the arguments
#define sum_long(VALUE) { SUM_LONG, { .as_long = (VALUE) } }
#define sum_ulong(VALUE) { SUM_ULONG, { .as_ulong = (VALUE) } }
#define sum_double(VALUE) { SUM_DOUBLE, { .as_double = (VALUE) } }

// our polymorphic function
long double _sum(size_t count, struct sum_arg * args)
{
    long double value = 0;

    for(size_t i = 0; i < count; ++i)
    {
        switch(args[i].type)
        {
            case SUM_LONG:
            value += args[i].value.as_long;
            break;

            case SUM_ULONG:
            value += args[i].value.as_ulong;
            break;

            case SUM_DOUBLE:
            value += args[i].value.as_double;
            break;
        }
    }

    return value;
}

// let's see if it works

#include <stdio.h>

int main()
{
    unsigned long foo = -1;
    long double value = sum(sum_long(42), sum_ulong(foo), sum_double(1e10));
    printf("%Le\n", value);
    return 0;
}

Recently, I used this .NET Metadata API. I have also written a blog post about it, that shows reading, updating, and removing the EXIF data from images using C#.

using (Metadata metadata = new Metadata("image.jpg"))
{
    IExif root = metadata.GetRootPackage() as IExif;
    if (root != null && root.ExifPackage != null)
    {
        Console.WriteLine(root.ExifPackage.DateTime);
     }
}

try giving border in % for exapmle 0.1% according to your need.

String str= "somestring";
String[] values = str.split("\\D+"); 

There is a way to do this, without resorting to the system call, you need to incorporate a wrapper something like this:

#include <sys/sendfile.h>
#include <fcntl.h>
#include <unistd.h>

/* 
** http://www.unixguide.net/unix/programming/2.5.shtml 
** About locking mechanism...
*/

int copy_file(const char *source, const char *dest){
   int fdSource = open(source, O_RDWR);

   /* Caf's comment about race condition... */
   if (fdSource > 0){
     if (lockf(fdSource, F_LOCK, 0) == -1) return 0; /* FAILURE */
   }else return 0; /* FAILURE */

   /* Now the fdSource is locked */

   int fdDest = open(dest, O_CREAT);
   off_t lCount;
   struct stat sourceStat;
   if (fdSource > 0 && fdDest > 0){
      if (!stat(source, &sourceStat)){
          int len = sendfile(fdDest, fdSource, &lCount, sourceStat.st_size);
          if (len > 0 && len == sourceStat.st_size){
               close(fdDest);
               close(fdSource);

               /* Sanity Check for Lock, if this is locked -1 is returned! */
               if (lockf(fdSource, F_TEST, 0) == 0){
                   if (lockf(fdSource, F_ULOCK, 0) == -1){
                      /* WHOOPS! WTF! FAILURE TO UNLOCK! */
                   }else{
                      return 1; /* Success */
                   }
               }else{
                   /* WHOOPS! WTF! TEST LOCK IS -1 WTF! */
                   return 0; /* FAILURE */
               }
          }
      }
   }
   return 0; /* Failure */
}

The above sample (error checking is omitted!) employs open, close and sendfile.

Edit: As caf has pointed out a race condition can occur between the open and stat so I thought I'd make this a bit more robust...Keep in mind that the locking mechanism varies from platform to platform...under Linux, this locking mechanism with lockf would suffice. If you want to make this portable, use the #ifdef macros to distinguish between different platforms/compilers...Thanks caf for spotting this...There is a link to a site that yielded "universal locking routines" here.

You could search for:

<li><a href="#">[^\n]+

And replace with:

$0</a>

Where $0 is the whole match. The exact semantics will depend on the language are you using though.

WARNING: You should avoid parsing HTML with regex. Here's why.

var textValue = $("input[type=text]").val()

this will get all values of all text boxes. You can use methods like children, firstchild, etc to hone in. Like by form $('form[name=form1] input[type=text]') Easier to use IDs for targeting elements but if it's purely dynamic you can get all input values then loop through then with JS.

I had this problem in a solution with a Web API project and several library projects. One of the library projects was borking on build, with errors that said the Unity attributes weren't "valid" attributes, and then one error said I needed to reference System.Runtime.

After much searching, reinstalling the 4.5.2 Developer Pack, and nothing working, I figured maybe it was just a version mismatch. So I looked at the properties of every project, and one of the very base libraries was targeting 4.5 while every other one was targeting 4.5.2. I changed that one to also target 4.5.2 and the errors went away.

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

You can use

@PostConstruct
public void init() {
   // ...
}

The PowerShell is almost exactly the same.

$webclient = new-object System.Net.WebClient
$webclient.Credentials = new-object System.Net.NetworkCredential($username, $password, $domain)
$webpage = $webclient.DownloadString($url)

Generally speaking an HTTP POST assumes the content of the body contains a series of key/value pairs that are created (most usually) by a form on the HTML side. You don't set the values using setHeader, as that won't place them in the content body.

So with your second test, the problem that you have here is that your client is not creating multiple key/value pairs, it only created one and that got mapped by default to the first argument in your method.

There are a couple of options you can use. First, you could change your method to accept only one input parameter, and then pass in a JSON string as you do in your second test. Once inside the method, you then parse the JSON string into an object that would allow access to the fields.

Another option is to define a class that represents the fields of the input types and make that the only input parameter. For example

class MyInput
{
    String str1;
    String str2;

    public MyInput() { }
      //  getters, setters
 }

@POST
@Consumes({"application/json"})
@Path("create/")
public void create(MyInput in){
System.out.println("value 1 = " + in.getStr1());
System.out.println("value 2 = " + in.getStr2());
}

Depending on the REST framework you are using it should handle the de-serialization of the JSON for you.

The last option is to construct a POST body that looks like:

str1=value1&str2=value2

then add some additional annotations to your server method:

public void create(@QueryParam("str1") String str1, 
                  @QueryParam("str2") String str2)

@QueryParam doesn't care if the field is in a form post or in the URL (like a GET query).

If you want to continue using individual arguments on the input then the key is generate the client request to provide named query parameters, either in the URL (for a GET) or in the body of the POST.

Use setInterval:

$(function(){
setInterval(oneSecondFunction, 1000);
});

function oneSecondFunction() {
// stuff you want to do every second
}

Here's an article on the difference between setTimeout and setInterval. Both will provide the functionality you need, they just require different implementations.

Push only single file

git commit -m "Message goes here" filename

Push only two files.

git commit -m "Message goes here" file1 file2

Try this:

foreach (Item item in myItemsList)
{
  if (SkipCondition) continue;
  // More stuff here
}

GitHub for Windows on Windows 7 currently installs Git in a path similar to this:

C:\Users\{username}\AppData\Local\GitHub\PortableGit_93e8418133eb85e81a81e5e19c272776524496c6\bin\git.exe

The guid after PortableGit_ may well be different on your system.

This should work:

int hh, mm, ss;
struct tm when = {0};

sscanf_s(date, "%d:%d:%d", &hh, &mm, &ss);


when.tm_hour = hh;
when.tm_min = mm;
when.tm_sec = ss;

time_t converted;
converted = mktime(&when);

Modify as needed.

As described in the IPv6 Wikipedia article,

IPv6 addresses are normally written as eight groups of four hexadecimal digits, where each group is separated by a colon (:)

A typical IPv6 address:

2001:0db8:85a3:0000:0000:8a2e:0370:7334

This is 39 characters long. IPv6 addresses are 128 bits long, so you could conceivably use a binary(16) column, but I think I'd stick with an alphanumeric representation.

The arguments can never be null. They just wont exist.

In other words, what you need to do is check the length of your arguments.

public static void main(String[] args)
{
    // Check how many arguments were passed in
    if(args.length == 0)
    {
        System.out.println("Proper Usage is: java program filename");
        System.exit(0);
    }
}

There is a way to do it slightly faster than in Yaroslav's answer by using get_operations. Here is a quick example:

import tensorflow as tf

a = tf.constant(1.3, name='const_a')
b = tf.Variable(3.1, name='variable_b')
c = tf.add(a, b, name='addition')
d = tf.multiply(c, a, name='multiply')

for op in tf.get_default_graph().get_operations():
    print(str(op.name))

I wrote a program with wpf and used Database for showing images and this is my code:

SqlConnection con = new SqlConnection(@"Data Source=HITMAN-PC\MYSQL;
                                      Initial Catalog=Payam;
                                      Integrated Security=True");

SqlDataAdapter da = new SqlDataAdapter("select * from news", con);

DataTable dt = new DataTable();
da.Fill(dt);

string adress = dt.Rows[i]["ImgLink"].ToString();
ImageSource imgsr = new BitmapImage(new Uri(adress));
PnlImg.Source = imgsr;

You can also use the pipeline stage to perform checks on a sub-docunment array

Here's the example using python (sorry I'm snake people).

db.products.aggregate([
  { '$lookup': {
      'from': 'products',
      'let': { 'pid': '$products' },
      'pipeline': [
        { '$match': { '$expr': { '$in': ['$_id', '$$pid'] } } }
        // Add additional stages here 
      ],
      'as':'productObjects'
  }
])

The catch here is to match all objects in the ObjectId array (foreign _id that is in local field/prop products).

You can also clean up or project the foreign records with additional stages, as indicated by the comment above.

A great resource to pick the correct HTTP error code for your API: http://www.codetinkerer.com/2015/12/04/choosing-an-http-status-code.html

An excerpt from the article:

Where to start:

2XX/3XX:

4XX:

5XX:

In eclipse try to go to file properties (Alt+Enter) and change the Resource → 'Text File encoding' → Other to UTF-8. Reopen the file and check there will be junk character somewhere in the string/file. Remove it. Save the file.

Change the encoding Resource → 'Text File encoding' back to Default.

Compile and deploy the code.

This approach takes care of spaces within the values, but requires a loop:

#!/bin/bash

FOO=( a b c )
BAR=""

for index in ${!FOO[*]}
do
    BAR="$BAR,${FOO[$index]}"
done
echo ${BAR:1}

private List<object> ConvertArrayToList(object[] array)
{
  List<object> list = new List<object>();

  foreach(object obj in array)
    list.add(obj);

  return list;
}

Yes, you're right. With the css() method you can retrieve the desired css value stored in the DOM. You can read more about this at: http://api.jquery.com/css/

But if you want to get its position you can check offset() and position() methods to get it's position.

this is a mysql function example. I hope it helps. (I have not tested it yet, but should work)

DROP FUNCTION IF EXISTS F_TEST //
CREATE FUNCTION F_TEST(PID INT) RETURNS VARCHAR
BEGIN
/*DECLARE VALUES YOU MAY NEED, EXAMPLE:
  DECLARE NOM_VAR1 DATATYPE [DEFAULT] VALUE;
  */
  DECLARE NAME_FOUND VARCHAR DEFAULT "";

    SELECT EMPLOYEE_NAME INTO NAME_FOUND FROM TABLE_NAME WHERE ID = PID;
  RETURN NAME_FOUND;
END;//

You just have to change the structure of the if...else..endif somewhat:

if exists(select * from Table where FieldValue='') then begin
  select TableID from Table where FieldValue=''
end else begin
  insert into Table (FieldValue) values ('')
  select TableID from Table where TableID = scope_identity()
end

You could also do:

if not exists(select * from Table where FieldValue='') then begin
  insert into Table (FieldValue) values ('')
end
select TableID from Table where FieldValue=''

Or:

if exists(select * from Table where FieldValue='') then begin
  select TableID from Table where FieldValue=''
end else begin
  insert into Table (FieldValue) values ('')
  select scope_identity() as TableID
end

For anyone else finding this - its worth noting that you can set the key value in the input name. Thanks to the answer in POSTing Form Fields with same Name Attribute you also can interplay strings or integers without quoting.

The answers assume that you don't mind the key value coming back for PHP however you can set name=[yourval] (string or int) which then allows you to refer to an existing record.

As suggested you need to use ng-options and unfortunately I believe you need to reference the array element for a default (unless the array is an array of strings).

http://jsfiddle.net/FxM3B/3/

The JavaScript:

function AppCtrl($scope) {


    $scope.operators = [
        {value: 'eq', displayName: 'equals'},
        {value: 'neq', displayName: 'not equal'}
     ]

    $scope.filterCondition={
        operator: $scope.operators[0]
    }
}

The HTML:

<body ng-app ng-controller="AppCtrl">
<div>Operator is: {{filterCondition.operator.value}}</div>
<select ng-model="filterCondition.operator" ng-options="operator.displayName for operator in operators">
</select>
</body>

Offering another potential solution to this error.

If you have a frontend application that makes API calls to the backend, make sure you reference the domain name that the certificate has been issued to.

e.g.

https://example.com/api/etc

and not

https://123.4.5.6/api/etc

In my case, I was making API calls to a secure server with a certificate, but using the IP instead of the domain name. This threw a Failed to load resource: net::ERR_INSECURE_RESPONSE.

I had the same problem but it had nothing to do with annotations. The problem happened while indexing beans in my container (Jboss EAP 6.3). One of my beans could not be indexed because it used Java 8 features an I got this sneaky little warning while deploying:

WARN [org.jboss.as.server.deployment] ... Could not index class ... java.lang.IllegalStateException: Unknown tag! pos=20 poolCount = 133

Then at the injection point I got the error:

Unsatisfied dependencies for type ... with qualifiers @Default

The solution is to update the Java annotations index. download new version of jandex (jandex-1.2.3.Final or newer) then put it into

JBOSS_HOME\modules\system\layers\base\org\jboss\jandex\main and then update reference to the new file in module.xml

NOTE: EAP 6.4.x already have this fixed

Private functions cannot access the public variables using module pattern

If you need access to the internal states of a function, you're possibly better off using a class. You can make a class instance behave like a function by making it a callable, which is done by defining __call__:

class StatefulFunction( object ):
    def __init__( self ):
        self.public_value = 'foo'

    def __call__( self ):
        return self.public_value


>> f = StatefulFunction()
>> f()
`foo`
>> f.public_value = 'bar'
>> f()
`bar`

Here is my solution:

dependencies: Gmaps.js, jQuery

var Maps = function($) {
   var lost_addresses = [],
       geocode_count  = 0;

   var addMarker = function() { console.log('Marker Added!') };

   return {
     getGecodeFor: function(addresses) {
        var latlng;
        lost_addresses = [];
        for(i=0;i<addresses.length;i++) {
          GMaps.geocode({
            address: addresses[i],
            callback: function(response, status) {
              if(status == google.maps.GeocoderStatus.OK) {
                addMarker();
              } else if(status == google.maps.GeocoderStatus.OVER_QUERY_LIMIT) {
                lost_addresses.push(addresses[i]);
              }

               geocode_count++;
               // notify listeners when the geocode is done
               if(geocode_count == addresses.length) {
                 $.event.trigger({ type: 'done:geocoder' });
               }
            }
          });
        }
     },
     processLostAddresses: function() {
       if(lost_addresses.length > 0) {
         this.getGeocodeFor(lost_addresses);
       }
     }
   };
}(jQuery);

Maps.getGeocodeFor(address);

// listen to done:geocode event and process the lost addresses after 1.5s
$(document).on('done:geocode', function() {
  setTimeout(function() {
    Maps.processLostAddresses();
  }, 1500);
});

Still broken? Try uninstalling @types/moment.

So, I removed @types/moment package from the package.json file and it worked using:

import * as moment from 'moment'

Newer versions of moment don't require the @types/moment package as types are already included.

The # means that it matches the id of an element. The . signifies the class name:

<div id="myRedText">This will be red.</div>
<div class="blueText">this will be blue.</div>


#myRedText {
    color: red;
}
.blueText {
    color: blue;
}

Note that in a HTML document, the id attribute must be unique, so if you have more than one element needing a specific style, you should use a class name.

Sometimes it is helpful to avoid creating a compile-time dependency between two view controllers. Here's how you can do it without caring about the type of the destination view controller:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.destinationViewController respondsToSelector:@selector(setMyData:)]) {
        [segue.destinationViewController performSelector:@selector(setMyData:) 
                                              withObject:myData];
    } 
}

So as long as your destination view controller declares a public property, e.g.:

@property (nonatomic, strong) MyData *myData;

you can set this property in the previous view controller as I described above.

1. My experimenting indicates that the runas command must include the admin user's domain (at least it does in my organization's environmental setup):

   runas /user:AdminDomain\AdminUserName ExampleScript.bat
   

   If you don’t already know the admin user's domain, run an instance of Command Prompt as the admin user, and enter the following command:

   echo %userdomain%
   

2. The answers provided by both Kerrek SB and Ed Greaves will execute the target file under the admin user but, if the file is a Command script (.bat file) or VB script (.vbs file) which attempts to operate on the normal-login user’s environment (such as changing registry entries), you may not get the desired results because the environment under which the script actually runs will be that of the admin user, not the normal-login user! For example, if the file is a script that operates on the registry’s HKEY_CURRENT_USER hive, the affected “current-user” will be the admin user, not the normal-login user.

More examples:

int i = (int)19.5f; // (precision is lost)
id someObject = [NSMutableArray new]; // you don't need to cast id explicitly

If you're not able to use NewChart.js you just need to change the way to set the color using array instead. Find the helper iteration inside Chart.js:

Replace this line:

fillColor : dataset.fillColor,

For this one:

fillColor : dataset.fillColor[index],

The resulting code:

//Iterate through each of the datasets, and build this into a property of the chart
  helpers.each(data.datasets,function(dataset,datasetIndex){

    var datasetObject = {
      label : dataset.label || null,
      fillColor : dataset.fillColor,
      strokeColor : dataset.strokeColor,
      bars : []
    };

    this.datasets.push(datasetObject);

    helpers.each(dataset.data,function(dataPoint,index){
      //Add a new point for each piece of data, passing any required data to draw.
      datasetObject.bars.push(new this.BarClass({
        value : dataPoint,
        label : data.labels[index],
        datasetLabel: dataset.label,
        strokeColor : dataset.strokeColor,
        //Replace this -> fillColor : dataset.fillColor,
        // Whith the following:
        fillColor : dataset.fillColor[index],
        highlightFill : dataset.highlightFill || dataset.fillColor,
        highlightStroke : dataset.highlightStroke || dataset.strokeColor
      }));
    },this);

  },this);

And in your js:

datasets: [
                {
                  label: "My First dataset",
                  fillColor: ["rgba(205,64,64,0.5)", "rgba(220,220,220,0.5)", "rgba(24,178,235,0.5)", "rgba(220,220,220,0.5)"],
                  strokeColor: "rgba(220,220,220,0.8)",
                  highlightFill: "rgba(220,220,220,0.75)",
                  highlightStroke: "rgba(220,220,220,1)",
                  data: [2000, 1500, 1750, 50]
                }
              ]

Are you sure that this is a bottleneck? Have you done any performance analysis?

Try using the NetBeans profiler (its free and built into NB 6.1) to look at hotspots.

Finally, a JVM upgrade (say from 1.5->1.6) is often a cheap performance booster. Even an upgrade in build number can provide good performance boosts. If you are running on Windows and this is a server class application, use -server on the command line to use the Server Hotspot JVM. On Linux and Solaris machines this is autodetected.

I personally prefer this pattern which is slightly clearer and simpler, at the expense of an extra variable:

for (auto it = m.cbegin(), next_it = it; it != m.cend(); it = next_it)
{
  ++next_it;
  if (must_delete)
  {
    m.erase(it);
  }
}

Advantages of this approach:

• the for loop incrementor makes sense as an incrementor;
• the erase operation is a simple erase, rather than being mixed in with increment logic;
• after the first line of the loop body, the meaning of it and next_it remain fixed throughout the iteration, allowing you to easily add additional statements referring to them without headscratching over whether they will work as intended (except of course that you cannot use it after erasing it).

$filename = "jquery.js.php";
$ext = pathinfo($filename, PATHINFO_EXTENSION);//will output: php
$file_basename = pathinfo($filename, PATHINFO_FILENAME);//will output: jquery.js

Your error looks like you are duplicating an already existing Primary Key in your DB. You should modify your sql code to implement its own primary key by using something like the IDENTITY keyword.

import java.util.Scanner;

public class LargestSmallestNum {

    public void findLargestSmallestNo() {

        int smallest = Integer.MAX_VALUE;
        int large = 0;
        int num;

        System.out.println("enter the number");

        Scanner input = new Scanner(System.in);

        int n = input.nextInt();

        for (int i = 0; i < n; i++) {

            num = input.nextInt();

            if (num > large)
                large = num;

            if (num < smallest)
                smallest = num;

            System.out.println("the largest is:" + large);
            System.out.println("Smallest no is : "  + smallest);
        }
    }

    public static void main(String...strings){
        LargestSmallestNum largestSmallestNum = new LargestSmallestNum();
        largestSmallestNum.findLargestSmalestNo();
    }
}

Whenever you are trying to compare the strings, compare them with respect to each character. For this you can use built in string function called strcmp(input1,input2); and you should use the header file called #include<string.h>

Try this code:

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

int main() 
{ 
    char s[]="STACKOVERFLOW";
    char s1[200];
    printf("Enter the string to be checked\n");//enter the input string
    scanf("%s",s1);
    if(strcmp(s,s1)==0)//compare both the strings  
    {
        printf("Both the Strings match\n"); 
    } 
    else
    {
        printf("Entered String does not match\n");  
    } 
    system("pause");  
} 

Try this

ImageView img
    Bitmap bmp;
    int width=100;
    int height=100;
    img=(ImageView)findViewById(R.id.imgView);
    bmp=BitmapFactory.decodeResource(getResources(),R.drawable.image);//image is your image                                                            
    bmp=Bitmap.createScaledBitmap(bmp, width,height, true);
    img.setImageBitmap(bmp);

Or If you want to load complete image size in memory then you can use

<ImageView
    android:id="@+id/img"
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:src="@drawable/image" 
    android:scaleType="fitXY"/>

Currently, media organisation is possible.

The "problem" with the media library in wordpress is always interesting. Check the following plugin to solve this: WordPress Real Media Library. WP RML creates a virtual folder structure based on an own taxonomy.

It allows you to organize your wordpress media library in a nice way with folders. It is easy to use, just drag&drop your files and move it to a specific folder. Filter when inserting media or create a gallery from a folder.

Turn your WordPress media library to the next level with folders / categories. Get organized with thousands of images.

RML (Real Media Library) is one of the most wanted media wordpress plugins. It is easy to use and it allows you to organize your thousands of images in folders. It is similar to wordpress categories like in the posts.

Use your mouse (or touch) to drag and drop your files. Create, rename, delete or reorder your folders If you want to select a image from the “Select a image”-dialog (e. g. featured image) you can filter when inserting media. Just install this plugin and it works fine with all your image and media files. It also supports multisite.

If you buy, you get: Forever FREE updates and high quality and fast support.

From the product description i can quote. If you want to try the plugin, there is also a demo on the plugin page.

Update #1 (2017-01-27): Manage your uploads physically

A long time ago I started to open this thread and now there is a usable extension plugin for Real Media Library which allows you to physically manage your uploads folder.

Check out this plugin: https://wordpress.org/plugins/physical-custom-upload-folder/

Do you know the wp-content/uploads folder? There, the files are stored in year/month based folders. This can be a very complicated and mass process, especially when you are working with a FTP client like FileZilla.

Moving already uploaded files: This plugin does not allow to move the files physically when you move a file in the Real Media Library because WordPress uses the URL's in different places. It is very hard to maintain such a process. So this only works for new uploads.

Physical organisation on server?

(Please read on if you are developer) I as developer thought about a solution about this. Does it make sense to organize the uploads on server, too? Yes, i think. Many people ask to organize it physically. I think also that the process of moving files on server and updating the image references is very hard to develop. There are many plugins out now, which are saving the URLs in their own-created database-tables.

Please check this thread where i explained the problem: https://wordpress.stackexchange.com/questions/226675/physical-organization-of-wordpress-media-library-real-media-library-plugin

If you want an alert to appear after a certain about time, you can use this code:

setTimeout(function() { alert("my message"); }, time);

If you want an alert to appear and disappear after a specified interval has passed, then you're out of luck. When an alert has fired, the browser stops processing the javascript code until the user clicks "ok". This happens again when a confirm or prompt is shown.

If you want the appear/disappear behavior, then I would recommend using something like jQueryUI's dialog widget. Here's a quick example on how you might use it to achieve that behavior.

var dialog = $(foo).dialog('open');
setTimeout(function() { dialog.dialog('close'); }, time);

Short answer: use an unassigned user port

Over achiever's answer - Select and deploy a resource discovery solution. Have the server select a private port dynamically. Have the clients use resource discovery.

The risk that that a server will fail because the port it wants to listen on is not available is real; at least it's happened to me. Another service or a client might get there first.

You can almost totally reduce the risk from a client by avoiding the private ports, which are dynamically handed out to clients.

The risk that from another service is minimal if you use a user port. An unassigned port's risk is only that another service happens to be configured (or dyamically) uses that port. But at least that's probably under your control.

The huge doc with all the port assignments, including User Ports, is here: http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.txt look for the token Unassigned.

I know this is an old question but on Windows, this filters the git output to the files and changed line numbers:

(git diff -p --stat) | findstr "@@ --git"

diff --git a/dir1/dir2/file.cpp b/dir1/dir2/file.cpp
@@ -47,6 +47,7 @@ <some function name>
@@ -97,7 +98,7 @@ <another functon name>

To extract the files and the changed lines from that is a bit more work:

for /f "tokens=3,4* delims=-+ " %f in ('^(git diff -p --stat .^) ^| findstr ^"@@ --git^"') do @echo %f

a/dir1/dir2/file.cpp
47,7
98,7

If you only need the bool result, just use the return value and ignore the out parameter.

bool successfullyParsed = int.TryParse(str, out ignoreMe);
if (successfullyParsed){
    // ...
}

Edit: Meanwhile you can also have a look at the original source code:

System.Int32.TryParse

If i want to know how something is actually implemented, i'm using ILSpy to decompile the .NET-code.

This is the result:

// int
/// <summary>Converts the string representation of a number to its 32-bit signed integer equivalent. A return value indicates whether the operation succeeded.</summary>
/// <returns>true if s was converted successfully; otherwise, false.</returns>
/// <param name="s">A string containing a number to convert. </param>
/// <param name="result">When this method returns, contains the 32-bit signed integer value equivalent to the number contained in s, if the conversion succeeded, or zero if the conversion failed. The conversion fails if the s parameter is null, is not of the correct format, or represents a number less than <see cref="F:System.Int32.MinValue"></see> or greater than <see cref="F:System.Int32.MaxValue"></see>. This parameter is passed uninitialized. </param>
/// <filterpriority>1</filterpriority>
public static bool TryParse(string s, out int result)
{
    return Number.TryParseInt32(s, NumberStyles.Integer, NumberFormatInfo.CurrentInfo, out result);
}


// System.Number
internal unsafe static bool TryParseInt32(string s, NumberStyles style, NumberFormatInfo info, out int result)
{
    byte* stackBuffer = stackalloc byte[1 * 114 / 1];
    Number.NumberBuffer numberBuffer = new Number.NumberBuffer(stackBuffer);
    result = 0;
    if (!Number.TryStringToNumber(s, style, ref numberBuffer, info, false))
    {
        return false;
    }
    if ((style & NumberStyles.AllowHexSpecifier) != NumberStyles.None)
    {
        if (!Number.HexNumberToInt32(ref numberBuffer, ref result))
        {
            return false;
        }
    }
    else
    {
        if (!Number.NumberToInt32(ref numberBuffer, ref result))
        {
            return false;
        }
    }
    return true;
}

And no, i cannot see any Try-Catchs on the road:

I you have the char '9', it will store its ASCII code, so to get the int value, you have 2 ways

char x = '9';
int y = Character.getNumericValue(x);   //use a existing function
System.out.println(y + " " + (y + 1));  // 9  10

or

char x = '9';
int y = x - '0';                        // substract '0' code to get the difference
System.out.println(y + " " + (y + 1));  // 9  10

And it fact, this works also :

char x = 9;
System.out.println(">" + x + "<");     //>  < prints a horizontal tab
int y = (int) x;
System.out.println(y + " " + (y + 1)); //9 10

You store the 9 code, which corresponds to a horizontal tab (you can see when print as String, bu you can also use it as int as you see above

If you're using the memory you've allocated, then you're not doing anything wrong. It becomes a problem when you write functions (other than main) that allocate memory without freeing it, and without making it available to the rest of your program. Then your program continues running with that memory allocated to it, but no way of using it. Your program and other running programs are deprived of that memory.

Edit: It's not 100% accurate to say that other running programs are deprived of that memory. The operating system can always let them use it at the expense of swapping your program out to virtual memory (</handwaving>). The point is, though, that if your program frees memory that it isn't using then a virtual memory swap is less likely to be necessary.

I had the same problem on Windows 7 64-bit Pro. I adjusted network adapters binding using Control panel but nothing changed. Also metrics where showing that Win should use Ethernet adapter as primary, but it didn't.

Then a tried to uninstall Ethernet adapter driver and then install it again (without restart) and then I checked metrics for sure.

After this, Windows started prioritize Ethernet adapter.

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

you just need to use word boundary (\b) instead of ^ and $:

For me, I configured the build path to add JUnit 5 Library and also by adding the dependency

     <dependency> 
        <groupId>org.junit.platform</groupId> 
        <artifactId>junit-platform-launcher</artifactId> 
        <version>1.1.0</version> 
        <scope>test</scope> 
     </dependency>

seperately.

Here is a complete example

#include <thread>
#include <iostream>

class Wrapper {
   public:
      void member1() {
          std::cout << "i am member1" << std::endl;
      }
      void member2(const char *arg1, unsigned arg2) {
          std::cout << "i am member2 and my first arg is (" << arg1 << ") and second arg is (" << arg2 << ")" << std::endl;
      }
      std::thread member1Thread() {
          return std::thread([=] { member1(); });
      }
      std::thread member2Thread(const char *arg1, unsigned arg2) {
          return std::thread([=] { member2(arg1, arg2); });
      }
};
int main(int argc, char **argv) {
   Wrapper *w = new Wrapper();
   std::thread tw1 = w->member1Thread();
   std::thread tw2 = w->member2Thread("hello", 100);
   tw1.join();
   tw2.join();
   return 0;
}

Compiling with g++ produces the following result

g++ -Wall -std=c++11 hello.cc -o hello -pthread

i am member1
i am member2 and my first arg is (hello) and second arg is (100)

You can also just Marshal.Copy the bitmap data. No intermediary memorystream etc. and a fast memory copy. This should work on both 24-bit and 32-bit bitmaps.

public static byte[] BitmapToByteArray(Bitmap bitmap)
{

    BitmapData bmpdata = null;

    try
    {
        bmpdata = bitmap.LockBits(new Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadOnly, bitmap.PixelFormat);
        int numbytes = bmpdata.Stride * bitmap.Height;
        byte[] bytedata = new byte[numbytes];
        IntPtr ptr = bmpdata.Scan0;

        Marshal.Copy(ptr, bytedata, 0, numbytes);

        return bytedata;
    }
    finally
    {
        if (bmpdata != null)
            bitmap.UnlockBits(bmpdata);
    }

}

.

2. Choose "Additional options..." to bring up the archival menu. notes
3. Select "Set the channel message retention policy".
4. Set "Retain all messages for a specific number of days".
5. All messages older than this time are deleted permanently!

I usually set this option to "1 day" to leave the channel with some context, then I go back into the above settings, and set it's retention policy back to "default" to go continue storing them from now-on.

Notes:
Luke points out: If the option is hidden: you have to go to global workspace Admin settings, Message Retention & Deletion, and check "Let workspace members override these settings"

Code snippet above provides incorrect byte order in string, so I fixed it a bit.

char const hex[16] = { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A',   'B','C','D','E','F'};

std::string byte_2_str(char* bytes, int size) {
  std::string str;
  for (int i = 0; i < size; ++i) {
    const char ch = bytes[i];
    str.append(&hex[(ch  & 0xF0) >> 4], 1);
    str.append(&hex[ch & 0xF], 1);
  }
  return str;
}

It's currently working, I've just changed the operator > in order to work in the snippet, take a look:

window.onload = function() {_x000D_
_x000D_
  if (window.location.href.indexOf("test") <= -1) {_x000D_
    var search_span = document.getElementsByClassName("securitySearchQuery");_x000D_
    search_span[0].style.color = "blue";_x000D_
    search_span[0].style.fontWeight = "bold";_x000D_
    search_span[0].style.fontSize = "40px";_x000D_
_x000D_
  }_x000D_
_x000D_
}

Create a HttpRequestMessage, set the Method to GET, set your headers and then use SendAsync instead of GetAsync.

var client = new HttpClient();
var request = new HttpRequestMessage() {
    RequestUri = new Uri("http://www.someURI.com"),
    Method = HttpMethod.Get,
};
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("text/plain"));
var task = client.SendAsync(request)
    .ContinueWith((taskwithmsg) =>
    {
        var response = taskwithmsg.Result;

        var jsonTask = response.Content.ReadAsAsync<JsonObject>();
        jsonTask.Wait();
        var jsonObject = jsonTask.Result;
    });
task.Wait();

I use this script in my extension "Grab Any Media" and work fine ( like youtube case )

        ,observer = new MutationObserver(function(mutations) {

            mutations.forEach(function(mutation) {

                if (oldHref != document.location.href) {

                    oldHref = document.location.href;

                    /* Changed ! your code here */

                }

            });

        });

    var config = {
        childList: true,
        subtree: true
    };

    observer.observe(bodyList, config);

};

exit(X), where X is a number (according to the doc) should work. But it is not recommended by Apple and won't be accepted by the AppStore. Why? Because of these guidelines (one of my app got rejected):

We found that your app includes a UI control for quitting the app. This is not in compliance with the iOS Human Interface Guidelines, as required by the App Store Review Guidelines.

Please refer to the attached screenshot/s for reference.

The iOS Human Interface Guidelines specify,

"Always Be Prepared to Stop iOS applications stop when people press the Home button to open a different application or use a device feature, such as the phone. In particular, people don’t tap an application close button or select Quit from a menu. To provide a good stopping experience, an iOS application should:

Save user data as soon as possible and as often as reasonable because an exit or terminate notification can arrive at any time.

Save the current state when stopping, at the finest level of detail possible so that people don’t lose their context when they start the application again. For example, if your app displays scrolling data, save the current scroll position."

> It would be appropriate to remove any mechanisms for quitting your app.

Plus, if you try to hide that function, it would be understood by the user as a crash.

As Shafik already wrote you need to use the right format because scanf gets you a char. Don't hesitate to look here if u aren't sure about the usage: http://www.cplusplus.com/reference/cstdio/printf/

Hint: It's faster/nicer to write x=x+1; the shorter way: x++;

Sorry for answering what's answered just wanted to give him the link - the site was really useful to me all the time dealing with C.

if (listView1.Items.Count > 0)
{
    listView1.Items[0].Selected = true;
    listView1.Select();
}

list items do not appear selected unless the control has the focus (or you set the HideSelection property to false)

The selected answer is almost perfect, but depending on the space, items width can be not equal. (In my case it was critical). So i've ended up with this code which increases space a little bit, so items are all the same width.

   class GridSpacingItemDecoration(private val columnCount: Int, @Px preferredSpace: Int, private val includeEdge: Boolean): RecyclerView.ItemDecoration() {

    /**
     * In this algorithm space should divide by 3 without remnant or width of items can have a difference
     * and we want them to be exactly the same
     */
    private val space = if (preferredSpace % 3 == 0) preferredSpace else (preferredSpace + (3 - preferredSpace % 3))

    override fun getItemOffsets(outRect: Rect, view: View, parent: RecyclerView, state: RecyclerView.State?) {
        val position = parent.getChildAdapterPosition(view)

        if (includeEdge) {

            when {
                position % columnCount == 0 -> {
                    outRect.left = space
                    outRect.right = space / 3
                }
                position % columnCount == columnCount - 1 -> {
                    outRect.right = space
                    outRect.left = space / 3
                }
                else -> {
                    outRect.left = space * 2 / 3
                    outRect.right = space * 2 / 3
                }
            }

            if (position < columnCount) {
                outRect.top = space
            }

            outRect.bottom = space

        } else {

            when {
                position % columnCount == 0 -> outRect.right = space * 2 / 3
                position % columnCount == columnCount - 1 -> outRect.left = space * 2 / 3
                else -> {
                    outRect.left = space / 3
                    outRect.right = space / 3
                }
            }

            if (position >= columnCount) {
                outRect.top = space
            }
        }
    }

}

if you have a MSSQL compatible SQL dump you can convert it to MySQL queries one by one using this online tool

http://burrist.com/mstomy.php

Hope it saved your time

Try to test and initialize your arrays before you use them :

if( !isset($catagory[$i]) ) $catagory[$i] = '' ;
if( !isset($task[$i]) ) $task[$i] = '' ;
if( !isset($fullText[$i]) ) $fullText[$i] = '' ;
if( !isset($dueDate[$i]) ) $dueDate[$i] = '' ;
if( !isset($empId[$i]) ) $empId[$i] = '' ;

If $catagory[$i] doesn't exist, you create (Uninitialized) one ... that's all ; => PHP try to read on your table in the address $i, but at this address, there's nothing, this address doesn't exist => PHP return you a notice, and it put nothing to you string. So you code is not very clean, it takes you some resources that down you server's performance (just a very little).

Take care about your MySQL tables default values

if( !isset($dueDate[$i]) ) $dueDate[$i] = '0000-00-00 00:00:00' ;

or

if( !isset($dueDate[$i]) ) $dueDate[$i] = 'NULL' ;

You forgot the return types in your member function definitions:

int ttTree::ttTreeInsert(int value) { ... }
^^^               

and so on.

div.test td, div.test caption, div.test th 

works for me.

The child selector > does not work in IE6.

Iterables are nicer:

const matches = (text, pattern) => ({
  [Symbol.iterator]: function * () {
    const clone = new RegExp(pattern.source, pattern.flags);
    let match = null;
    do {
      match = clone.exec(text);
      if (match) {
        yield match;
      }
    } while (match);
  }
});

Usage in a loop:

for (const match of matches('abcdefabcdef', /ab/g)) {
  console.log(match);
}

Or if you want an array:

[ ...matches('abcdefabcdef', /ab/g) ]

Doxygen creates inheritance diagrams but I dont think it will create an entire class hierachy. It does allow you to use the GraphViz tool. If you use the Doxygen GUI frontend tool you will find the relevant options in Step2: -> Wizard tab -> Diagrams. The DOT relation options are under the Expert Tab.

sleep is a good way to avoid overload on the cpu

not sure if it's really clever, but I usually use

while(not sleep(5)):
    #code to execute

sleep method always returns None.

In addition to Richard Simões answer you can also use the Page Visibility API.

if (!document.hidden) {
    // do what you need
}

This specification defines a means for site developers to programmatically determine the current visibility state of the page in order to develop power and CPU efficient web applications.

Look into composite formatting:

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

You could also write (although it's not really recommended):

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

And, with the release of C# 6.0, you have string interpolation expressions:

Console.WriteLine($"{mon}.{da}.{yer}");  // note the $ prefix.

Found the solution:

It should be:

"{'Id1':'2','Id2':'2'}"

and not

"{'Id1':'2'},{'Id2':'2'}"

I have also faced this problem and the solution is:

1. open Solution Explore
2. double click on Program.cs file

I added this code again and my program ran accurately:

Application.Run(new PayrollSystem()); 
//File name this code removed by me accidentally.

Why does response.json return a promise?

Because you receive the response as soon as all headers have arrived. Calling .json() gets you another promise for the body of the http response that is yet to be loaded. See also Why is the response object from JavaScript fetch API a promise?.

Why do I get the value if I return the promise from the then handler?

Because that's how promises work. The ability to return promises from the callback and get them adopted is their most relevant feature, it makes them chainable without nesting.

You can use

fetch(url).then(response => 
    response.json().then(data => ({
        data: data,
        status: response.status
    })
).then(res => {
    console.log(res.status, res.data.title)
}));

or any other of the approaches to access previous promise results in a .then() chain to get the response status after having awaited the json body.

Please do NOT try to set $DISPLAY manually when connecting over SSH.
If you connect via SSH -X and $DISPLAY stays empty, this usually means that no encrypted channel could be established.

Most likely you are missing the package xauth or xorg-x11-xauth. Try to install it on the remote machine using:

sudo apt-get install xauth

or

sudo apt-get install xorg-x11-xauth

After that end and restart your SSH connection. Don't forget to use SSH -X so that X Window output is forwarded to your local machine.

Now try echo $DISPLAYagain to see if $DISPLAY has been set automatically by the SSH demon. It should show you a line with an IP address and a port.

try this

<div ng-app="myApp" ng-controller="customersCtrl"> 
  <div ng-include="'myTable.htm'"></div>
</div>

<script>
var app = angular.module('myApp', []);
app.controller('customersCtrl', function($scope, $http) {
    $http.get("customers.php").then(function (response) {
        $scope.names = response.data.records;
    });
});
</script>

I made a benchmark to test the performance of each solution that don't use external libraries.

The reduce() option, posted by @Nina Scholz seems to be the optimal one.

An other regex-based solution:

>>> strs = "foo\tbar\t\tspam"

>>> r = re.compile(r'([^\t]*)\t*')
>>> r.findall(strs)[:-1]
['foo', 'bar', 'spam']

Years ago, I implemented the following hashtable, which has had some features that have been missing to the Map class. However, that's no longer the case. Now it's possible to iterate over the entries of a Map, get an array of its keys or values or both (these operations are implemented copying to a newly allocated array, though — that's a waste of memory and its time complexity will always be as bad as O(n)), remove specific items given their key, and clear the whole map. Therefore, my hashtable implementation is only useful for compatibility purposes, though in this case it would be more appropriate to write a proper polyfill. I'd suggest to anyone who would use my hashtable implementation to change it so to make it become a polyfill for the Map class.

function Hashtable() {
    this._map = new Map();
    this._indexes = new Map();
    this._keys = [];
    this._values = [];
    this.put = function(key, value) {
        var newKey = !this.containsKey(key);
        this._map.set(key, value);
        if (newKey) {
            this._indexes.set(key, this.length);
            this._keys.push(key);
            this._values.push(value);
        }
    };
    this.remove = function(key) {
        if (!this.containsKey(key))
            return;
        this._map.delete(key);
        var index = this._indexes.get(key);
        this._indexes.delete(key);
        this._keys.splice(index, 1);
        this._values.splice(index, 1);
    };
    this.indexOfKey = function(key) {
        return this._indexes.get(key);
    };
    this.indexOfValue = function(value) {
        return this._values.indexOf(value) != -1;
    };
    this.get = function(key) {
        return this._map.get(key);
    };
    this.entryAt = function(index) {
        var item = {};
        Object.defineProperty(item, "key", {
            value: this.keys[index],
            writable: false
        });
        Object.defineProperty(item, "value", {
            value: this.values[index],
            writable: false
        });
        return item;
    };
    this.clear = function() {
        var length = this.length;
        for (var i = 0; i < length; i++) {
            var key = this.keys[i];
            this._map.delete(key);
            this._indexes.delete(key);
        }
        this._keys.splice(0, length);
    };
    this.containsKey = function(key) {
        return this._map.has(key);
    };
    this.containsValue = function(value) {
        return this._values.indexOf(value) != -1;
    };
    this.forEach = function(iterator) {
        for (var i = 0; i < this.length; i++)
            iterator(this.keys[i], this.values[i], i);
    };
    Object.defineProperty(this, "length", {
        get: function() {
            return this._keys.length;
        }
    });
    Object.defineProperty(this, "keys", {
        get: function() {
            return this._keys;
        }
    });
    Object.defineProperty(this, "values", {
        get: function() {
            return this._values;
        }
    });
    Object.defineProperty(this, "entries", {
        get: function() {
            var entries = new Array(this.length);
            for (var i = 0; i < entries.length; i++)
                entries[i] = this.entryAt(i);
            return entries;
        }
    });
}

The error regarding the file extension has been handled, you either use BMP (without the dot) or pass the output name with the extension already. Now to handle the error you need to properly modify your data in the frequency domain to be saved as an integer image, PIL is telling you that it doesn't accept float data to save as BMP.

Here is a suggestion (with other minor modifications, like using fftshift and numpy.array instead of numpy.asarray) for doing the conversion for proper visualization:

import sys
import numpy
from PIL import Image

img = Image.open(sys.argv[1]).convert('L')

im = numpy.array(img)
fft_mag = numpy.abs(numpy.fft.fftshift(numpy.fft.fft2(im)))

visual = numpy.log(fft_mag)
visual = (visual - visual.min()) / (visual.max() - visual.min())

result = Image.fromarray((visual * 255).astype(numpy.uint8))
result.save('out.bmp')

You can see your current session settings by querying nls_session_parameters:

select value
from nls_session_parameters
where parameter = 'NLS_NUMERIC_CHARACTERS';

VALUE                                  
----------------------------------------
.,                                       

That may differ from the database defaults, which you can see in nls_database_parameters.

In this session your query errors:

select to_number('100,12') from dual;

Error report -
SQL Error: ORA-01722: invalid number
01722. 00000 -  "invalid number"

I could alter my session, either directly with alter session or by ensuring my client is configured in a way that leads to the setting the string needs (it may be inherited from a operating system or Java locale, for example):

alter session set NLS_NUMERIC_CHARACTERS = ',.';
select to_number('100,12') from dual;

TO_NUMBER('100,12')
-------------------
             100,12 

In SQL Developer you can set your preferred value in Tool->Preferences->Database->NLS.

But I can also override that session setting as part of the query, with the optional third nlsparam parameter to to_number(); though that makes the optional second fmt parameter necessary as well, so you'd need to be able pick a suitable format:

alter session set NLS_NUMERIC_CHARACTERS = '.,';
select to_number('100,12', '99999D99', 'NLS_NUMERIC_CHARACTERS='',.''')
from dual;

TO_NUMBER('100,12','99999D99','NLS_NUMERIC_CHARACTERS='',.''')
--------------------------------------------------------------
                                                        100.12 

By default the result is still displayed with my session settings, so the decimal separator is still a period.

For IE 7 & 8 (and other browsers without CSS3 support not including IE6) you can use the following to get the 2nd and 3rd children:

2nd Child:

td:first-child + td

3rd Child:

td:first-child + td + td

Then simply add another + td for each additional child you wish to select.

If you want to support IE6 that can be done too! You simply need to use a little javascript (jQuery in this example):

$(function() {
    $('td:first-child').addClass("firstChild");
    $(".table-class tr").each(function() {
        $(this).find('td:eq(1)').addClass("secondChild");
        $(this).find('td:eq(2)').addClass("thirdChild");
    });
});

Then in your css you simply use those class selectors to make whatever changes you like:

table td.firstChild { /*stuff here*/ }
table td.secondChild { /*stuff to apply to second td in each row*/ }

for me this how I solve it:

• go to the build path of the current project

under Libraries

• select the "JRE System Library [jdk1.8xxx]"
• click edit
• and select either "Workspace default JRE(jdk1.8xx)" OR Alternate JRE
• Click finish
• Click OK

Note: make sure that in Eclipse / Preferences (NOT the project) / Java / Installed JRE ,that the jdk points to the JDK folder not the JRE C:\Program Files\Java\jdk1.8.0_74

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

To do so,

USE master ;
ALTER DATABASE model SET RECOVERY BULK_LOGGED ;

To change it back:

USE master ;
ALTER DATABASE model SET RECOVERY FULL ;

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

• First you need to create HubNode(Server) and start the HubNode(Server) from command Line/prompt using Java: -jar selenium-server-standalone-2.44.0.jar -role hub
• Then bind the node/Client to this Hub using Hub machines IPAddress or Name with any port number >1024. For Node Machine for example: Java -jar selenium-server-standalone-2.44.0.jar -role webdriver -hub http://HubmachineIPAddress:4444/grid/register -port 5566

One more thing is that whenever we use Internet Explore or Google Chrome we need to set: System.setProperty("webdriver.ie.driver",path);

Here's a way to get the list of people a user is following with just a browser and some copy-paste (A pure javascript solution based on Deep Seeker's answer):

1. Get the user's id (In a browser, navigate to https://www.instagram.com/user_name/?__a=1 and look for response -> graphql -> user -> id [from Deep Seeker's answer])

2. Open another browser window

3. Open the browser console and paste this in it

   _x000D_

   _x000D_

   options = {
       userId: your_user_id,
       list: 1 //1 for following, 2 for followers
   }

   _x000D_

   _x000D_
   _x000D_

4. change to your user id and hit enter

5. paste this in the console and hit enter

   _x000D_

   _x000D_

   `https://www.instagram.com/graphql/query/?query_hash=c76146de99bb02f6415203be841dd25a&variables=` + encodeURIComponent(JSON.stringify({
           "id": options.userId,
           "include_reel": true,
           "fetch_mutual": true,
           "first": 50
       }))

   _x000D_

   _x000D_
   _x000D_

6. Navigate to the outputted link

(This sets up the headers for the http request. If you try to run the script on a page where this isn't open, it won't work.)

7. In the console for the page you just opened, paste this and hit enter
   _x000D_

   _x000D_

   let config = {
     followers: {
       hash: 'c76146de99bb02f6415203be841dd25a',
       path: 'edge_followed_by'
     },
     following: {
       hash: 'd04b0a864b4b54837c0d870b0e77e076',
       path: 'edge_follow'
     }
   };
   
   var allUsers = [];
   
   function getUsernames(data) {
       var userBatch = data.map(element => element.node.username);
       allUsers.push(...userBatch);
   }
   
   async function makeNextRequest(nextCurser, listConfig) {
       var params = {
           "id": options.userId,
           "include_reel": true,
           "fetch_mutual": true,
           "first": 50
       };
       if (nextCurser) {
           params.after = nextCurser;
       }
       var requestUrl = `https://www.instagram.com/graphql/query/?query_hash=` + listConfig.hash + `&variables=` + encodeURIComponent(JSON.stringify(params));
   
       var xhr = new XMLHttpRequest();
       xhr.onload = function(e) {
           var res = JSON.parse(xhr.response);
   
           var userData = res.data.user[listConfig.path].edges;
           getUsernames(userData);
   
           var curser = "";
           try {
               curser = res.data.user[listConfig.path].page_info.end_cursor;
           } catch {
   
           }
           var users = [];
           if (curser) {
               makeNextRequest(curser, listConfig);
           } else {
               var printString =""
               allUsers.forEach(item => printString = printString + item + "\n");
               console.log(printString);
           }
       }
   
       xhr.open("GET", requestUrl);
       xhr.send();
   }
   
   if (options.list === 1) {
   
       console.log('following');
       makeNextRequest("", config.following);
   } else if (options.list === 2) {
   
       console.log('followers');
       makeNextRequest("", config.followers);
   }

After a few seconds it should output the list of users your user is following.

To push up through a given commit, you can write:

git push <remotename> <commit SHA>:<remotebranchname>

provided <remotebranchname> already exists on the remote. (If it doesn't, you can use git push <remotename> <commit SHA>:refs/heads/<remotebranchname> to autocreate it.)

If you want to push a commit without pushing previous commits, you should first use git rebase -i to re-order the commits.

If all of the above doesn't work for you:

window.location.reload();

This for some reason refreshed my iframe instead of the whole script. Maybe because it is placed in the frame itself, while all those getElemntById solutions work when you try to refresh a frame from another frame?

Or I don't understand this fully and talk gibberish, anyways this worked for me like a charm :)

Use $event.stopPropagation():

<div ng-controller="OverlayCtrl" class="overlay" ng-click="hideOverlay()">
    <img src="http://some_src" ng-click="nextImage(); $event.stopPropagation()" />
</div>

From a maintainability standpoint, it's much simpler to manage one item in one file, than it is to manage multiple items in possibly multiple files.

Separating your styling will help make your life much easier, especially when job duties are distributed amongst different individuals. Reusability and portability will save you plenty of time down the road.

When using an inline style, that will override any external properties that are set.

I tried the first solution and it works but the end user can easily identify that the div's are refreshing as it is fadeIn(), without fade in i tried .toggle().toggle() and it works perfect. you can try like this

$("#panel").toggle().toggle();

it works perfectly for me as i'm developing a messenger and need to minimize and maximize the chat box's and this does it best rather than the above code.

I believe this snippet will also be helpful in a situation where the dates comparison spans more than two entries.

static final int COMPARE_EARLIEST = 0;

static final int COMPARE_MOST_RECENT = 1;


public LocalDate getTargetDate(List<LocalDate> datesList, int comparatorType) { 
   LocalDate refDate = null;
   switch(comparatorType)
   {
       case COMPARE_EARLIEST:         
       //returns the most earliest of the date entries
          refDate = (LocalDate) datesList.stream().min(Comparator.comparing(item -> 
                      item.toDateTimeAtCurrentTime())).get();
          break;

       case COMPARE_MOST_RECENT:
          //returns the most recent of the date entries 
          refDate = (LocalDate) datesList.stream().max(Comparator.comparing(item -> 
                    item.toDateTimeAtCurrentTime())).get();
          break;
   }

   return refDate;
}

my problem was to copy the whole source files contains .idea directory and my webstorm terminal commands were run on the original directory of the source
I delete the .idea directory and it worked fine

assuming you have a SQL table called mydata - you can load data from a csv file as follows:

COPY MYDATA FROM '<PATH>/MYDATA.CSV' CSV HEADER;
