The point for diamond operator is simply to reduce typing of code when declaring generic types. It doesn't have any effect on runtime whatsoever.

The only difference if you specify in Java 5 and 6,

List<String> list = new ArrayList();

is that you have to specify @SuppressWarnings("unchecked") to the list (otherwise you will get an unchecked cast warning). My understanding is that diamond operator is trying to make development easier. It's got nothing to do on runtime execution of generics at all.

There looks to be an issue when the time of the phone/emulator is different to the one of the server (where react-native packager is running). In my case there was a 1 minute difference between the time of the phone and the computer. After synchronizing them (didn't do anything fancy, the phone was set on manual time, and I just set it to use the network(sim) provided time), everything worked fine. This github issue helped me find the problem.

Taken from the Java EE 6 SDK Installer, shows what SDK 6 contains besides JDK:

string URI = "site.com/mail.php";
using (WebClient client = new WebClient())
{
    System.Collections.Specialized.NameValueCollection postData = 
        new System.Collections.Specialized.NameValueCollection()
       {
              { "to", emailTo },  
              { "subject", currentSubject },
              { "body", currentBody }
       };
    string pagesource = Encoding.UTF8.GetString(client.UploadValues(URI, postData));
}

In mysql server 8.0, on Windows, the location is C:\ProgramData\MySQL\MySQL Server 8.0\Data

I would like to add a minor comment on Blender solution.

You can do the following:

var link = 'http://example.com?candy_name=' + encodeURIComponent('M&M');

That outputs:

http://example.com?candy_name=M%26M

The great thing about this it does not only work for & but for any especial character.

For instance:

var link = 'http://example.com?candy_name=' + encodeURIComponent('M&M?><')

Outputs:

"http://example.com?candy_name=M%26M%3F%3E%3C"

No, but you can do this almost as easily.

Go here:

https://romannurik.github.io/AndroidAssetStudio/

Build your icons using that page, and then download the zip package. Unzip it into the right directory and it'll overwrite all the drawable-*/ic_launcher.png correctly.

foreach($test_package_data as $key=>$data ) {

   $category_detail_arr = $test_package_data[$key]['category_detail'];

   foreach( $category_detail_arr as $i=>$value ) {
     $test_package_data[$key]['category_detail'][$i]['count'] = $some_value;////<----Here
   }

}

These commands worked for me:

jupyter notebook list # shows the running notebooks and their port-numbers
                      # (for instance: 8080)
lsof -n -i4TCP:[port-number] # shows PID.
kill -9 [PID] # kill the process.

This answer was adapted from here.

Seems like this sounds more complicated than it is...

    Dim myArray As String() = TextBox1.Lines
    'First we count how many null elements there are...
    Dim Counter As Integer = 0
    For x = 0 To myArray.Count - 1
        If Len(myArray(x)) < 1 Then
            Counter += 1
        End If
    Next
    'Then we dimension an array to be the size of the last array
    'minus the amount of nulls found...
    Dim tempArr(myArray.Count - Counter) As String

    'Indexing starts at zero, so let's set the stage for that...
    Counter = -1

    For x = 0 To myArray.Count - 1
        'Set the conditions for the new array as in
        'It .contains("word"), has no value, length is less than 1, ect.
        If Len(myArray(x)) > 1 Then
            Counter += 1
            'So if a value is present, we move that value over to
            'the new array.
            tempArr(Counter) = myArray(x)
        End If
    Next

Now you can assign tempArr back to the original or what ever you need done with it as in...

TextBox1.Lines = tempArr (You now have a textbox void of blank lines)

If you really need maximum copying performance (which you might not), use neither of them.

There's a lot that can be done to optimize memory copying - even more if you're willing to use multiple threads/cores for it. See, for example:

What's missing/sub-optimal in this memcpy implementation?

both the question and some of the answers have suggested implementations or links to implementations.

That only means that an undefined column or parameter name was detected. The errror that DB2 gives should point what that may be:

DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=[THE_UNDEFINED_COLUMN_OR_PARAMETER_NAME], DRIVER=4.8.87

Double check your table definition. Maybe you just missed adding something.

I also tried google-ing this problem and saw this:

http://www.coderanch.com/t/515475/JDBC/databases/sql-insert-statement-giving-sqlcode

I know this is an old question, but this is still a problem I keep walking into, and yet there is still no clear solution to do this correctly when using async/await in an async void signature method.

However, I noticed that .Wait() is working properly inside the void method.

and since async void and void have the same signature, you might need to do the following.

void LoadBlahBlah()
{
    blah().Wait(); //this blocks
}

Confusingly enough async/await does not block on the next code.

async void LoadBlahBlah()
{
    await blah(); //this does not block
}

When you decompile your code, my guess is that async void creates an internal Task (just like async Task), but since the signature does not support to return that internal Tasks

this means that internally the async void method will still be able to "await" internally async methods. but externally unable to know when the internal Task is complete.

So my conclusion is that async void is working as intended, and if you need feedback from the internal Task, then you need to use the async Task signature instead.

hopefully my rambling makes sense to anybody also looking for answers.

Edit: I made some example code and decompiled it to see what is actually going on.

static async void Test()
{
    await Task.Delay(5000);
}

static async Task TestAsync()
{
    await Task.Delay(5000);
}

Turns into (edit: I know that the body code is not here but in the statemachines, but the statemachines was basically identical, so I didn't bother adding them)

private static void Test()
{
    <Test>d__1 stateMachine = new <Test>d__1();
    stateMachine.<>t__builder = AsyncVoidMethodBuilder.Create();
    stateMachine.<>1__state = -1;
    AsyncVoidMethodBuilder <>t__builder = stateMachine.<>t__builder;
    <>t__builder.Start(ref stateMachine);
}
private static Task TestAsync()
{
    <TestAsync>d__2 stateMachine = new <TestAsync>d__2();
    stateMachine.<>t__builder = AsyncTaskMethodBuilder.Create();
    stateMachine.<>1__state = -1;
    AsyncTaskMethodBuilder <>t__builder = stateMachine.<>t__builder;
    <>t__builder.Start(ref stateMachine);
    return stateMachine.<>t__builder.Task;
}

neither AsyncVoidMethodBuilder or AsyncTaskMethodBuilder actually have any code in the Start method that would hint of them to block, and would always run asynchronously after they are started.

meaning without the returning Task, there would be no way to check if it is complete.

as expected, it only starts the Task running async, and then it continues in the code. and the async Task, first it starts the Task, and then it returns it.

so I guess my answer would be to never use async void, if you need to know when the task is done, that is what async Task is for.

Already good answer there. Just add a benchmark result for StringBuffer and StringBuild performance difference use new instance in loop or use setLength(0) in loop.

The summary is: In a large loop

• StringBuilder is much faster than StringBuffer
• Create new StringBuilder instance in loop have no difference with setLength(0). (setLength(0) have very very very tiny advantage than create new instance.)
• StringBuffer is slower than StringBuilder by create new instance in loop
• setLength(0) of StringBuffer is extremely slower than create new instance in loop.

Very simple benchmark (I just manually changed the code and do different test ):

public class StringBuilderSpeed {
public static final char ch[] = new char[]{'a','b','c','d','e','f','g','h','i'};

public static void main(String a[]){
    int loopTime = 99999999;
    long startTime = System.currentTimeMillis();
    StringBuilder sb = new StringBuilder();
    for(int i = 0 ; i < loopTime; i++){
        for(char c : ch){
            sb.append(c);
        }
        sb.setLength(0);
    }
    long endTime = System.currentTimeMillis();
    System.out.println("Time cost: " + (endTime - startTime));
}

}

New StringBuilder instance in loop: Time cost: 3693, 3862, 3624, 3742

StringBuilder setLength: Time cost: 3465, 3421, 3557, 3408

New StringBuffer instance in loop: Time cost: 8327, 8324, 8284

StringBuffer setLength Time cost: 22878, 23017, 22894

Again StringBuilder setLength to ensure not my labtop got some issue to use such long for StringBuffer setLength :-) Time cost: 3448

A nice solution without using interop:

As always, simply enable DoubleBuffered=true on your CustomControl. Then, if you have any containers like FlowLayoutPanel or TableLayoutPanel, derive a class from each of these types and in the constructors, enable double buffering. Now, simply use your derived Containers instead of the Windows.Forms Containers.

class TableLayoutPanel : System.Windows.Forms.TableLayoutPanel
{
    public TableLayoutPanel()
    {
        DoubleBuffered = true;
    }
}

class FlowLayoutPanel : System.Windows.Forms.FlowLayoutPanel
{
    public FlowLayoutPanel()
    {
        DoubleBuffered = true;
    }
}

Some cookies, such as referrer urls, have = in them. As a result, simply splitting on = will cause irregular results, and the previous answers here will breakdown over time (or immediately depending on your depth of use).

This takes only the first instance of the equals sign. It returns an object with the cookie's key value pairs.

// Returns an object of key value pairs for this page's cookies
function getPageCookies(){

    // cookie is a string containing a semicolon-separated list, this split puts it into an array
    var cookieArr = document.cookie.split(";");

    // This object will hold all of the key value pairs
    var cookieObj = {};

    // Iterate the array of flat cookies to get their key value pair
    for(var i = 0; i < cookieArr.length; i++){

        // Remove the standardized whitespace
        var cookieSeg = cookieArr[i].trim();

        // Index of the split between key and value
        var firstEq = cookieSeg.indexOf("=");

        // Assignments
        var name = cookieSeg.substr(0,firstEq);
        var value = cookieSeg.substr(firstEq+1);
        cookieObj[name] = value;
   }
   return cookieObj;
}

As BalausC mentioned in a comment, you are probably looking for CSS (Cascading Style Sheets) not HTML attributes.

To position an element, a <table> in your case you want to use either padding or margins.

the difference between margins and paddings can be seen as the "box model":

Image from HTML Dog article on margins and padding http://www.htmldog.com/guides/cssbeginner/margins/.

I highly recommend the article above if you need to learn how to use CSS.

To move the table down and right I would use margins like so:

table{
    margin:25px 0 0 25px;
}

This is in shorthand so the margins are as follows:

margin: top right bottom left;

or alternatively you could not bother coding for it and use the 'conditional formatting' function in Excel which will set the background colour and font colour based on cell value.

There are only two variables here so set the default to yellow and then overwrite when the value is greater than or less than your threshold values.

I use __get (and public properties) as much as possible, because they make code much more readable. Compare:

this code unequivocally says what i'm doing:

echo $user->name;

this code makes me feel stupid, which i don't enjoy:

function getName() { return $this->_name; }
....

echo $user->getName();

The difference between the two is particularly obvious when you access multiple properties at once.

echo "
    Dear $user->firstName $user->lastName!
    Your purchase:
        $product->name  $product->count x $product->price
"

and

echo "
    Dear " . $user->getFirstName() . " " . $user->getLastName() . "
    Your purchase: 
        " . $product->getName() . " " . $product->getCount() . "  x " . $product->getPrice() . " ";

Whether $a->b should really do something or just return a value is the responsibility of the callee. For the caller, $user->name and $user->accountBalance should look the same, although the latter may involve complicated calculations. In my data classes i use the following small method:

 function __get($p) { 
      $m = "get_$p";
      if(method_exists($this, $m)) return $this->$m();
      user_error("undefined property $p");
 }

when someone calls $obj->xxx and the class has get_xxx defined, this method will be implicitly called. So you can define a getter if you need it, while keeping your interface uniform and transparent. As an additional bonus this provides an elegant way to memorize calculations:

  function get_accountBalance() {
      $result = <...complex stuff...>
      // since we cache the result in a public property, the getter will be called only once
      $this->accountBalance = $result;
  }

  ....


   echo $user->accountBalance; // calculate the value
   ....
   echo $user->accountBalance; // use the cached value

Bottom line: php is a dynamic scripting language, use it that way, don't pretend you're doing Java or C#.

This was a feature request that got fixed in Django 1.3.

Here's the bug: https://code.djangoproject.com/ticket/10427

Basically, if you're running something after 1.3, in Django templates you can do:

{{ form.field.value|default_if_none:"" }}

Or in Jinja2:

{{ form.field.value()|default("") }}

Note that field.value() is a method, but in Django templates ()'s are omitted, while in Jinja2 method calls are explicit.

If you want to know what version of Django you're running, it will tell you when you do the runserver command.

If you are on something prior to 1.3, you can probably use the fix posted in the above bug: https://code.djangoproject.com/ticket/10427#comment:24

    // this will give all the forms on the page.

    $('form')

   // If you know the name of form then.

    $('form[name="myFormName"]')

  //  If you don't know know the name but the position (starts with 0)

    $('form:eq(1)')  // 2nd form will be fetched.

just seperate the class name with a comma.

.a,.b{
your styles
}

This will select all rows where some_col is NULL or '' (empty string)

SELECT * FROM table WHERE some_col IS NULL OR some_col = '';

Full example with printed variables at partition step:

def partition(data, p, right):
    print("\n==> Enter partition: p={}, right={}".format(p, right))
    pivot = data[right]
    print("pivot = data[{}] = {}".format(right, pivot))

    i = p - 1  # this is a dangerous line

    for j in range(p, right):
        print("j: {}".format(j))
        if data[j] <= pivot:
            i = i + 1
            print("new i: {}".format(i))
            print("swap: {} <-> {}".format(data[i], data[j]))
            data[i], data[j] = data[j], data[i]

    print("swap2: {} <-> {}".format(data[i + 1], data[right]))
    data[i + 1], data[right] = data[right], data[i + 1]
    return i + 1


def quick_sort(data, left, right):
    if left < right:
        pivot = partition(data, left, right)
        quick_sort(data, left, pivot - 1)
        quick_sort(data, pivot + 1, right)

data = [2, 8, 7, 1, 3, 5, 6, 4]

print("Input array: {}".format(data))
quick_sort(data, 0, len(data) - 1)
print("Output array: {}".format(data))

If you are using C++ 17 you can just use the inline specifier (see https://stackoverflow.com/a/11711082/55721)

If using older versions of the C++ standard, you must add the definitions to match your declarations of X and Y

unsigned char test::X;
unsigned char test::Y;

somewhere. You might want to also initialize a static member

unsigned char test::X = 4;

and again, you do that in the definition (usually in a CXX file) not in the declaration (which is often in a .H file)

On the right side of tab "Devices logcat" there is the button "Show only Logcat from selected Process". Its not perfect, because everytime I run another process I need to push it again, but thats the only solution that works for me. So far...

Just for fun, here's a sample with a recursive function which (I hope) should be a bit simpler to understand and to use with your code:

Function Recurse(sPath As String) As String

    Dim FSO As New FileSystemObject
    Dim myFolder As Folder
    Dim mySubFolder As Folder

    Set myFolder = FSO.GetFolder(sPath)
    For Each mySubFolder In myFolder.SubFolders
        Call TestSub(mySubFolder.Path)
        Recurse = Recurse(mySubFolder.Path)
    Next

End Function

Sub TestR()

    Call Recurse("D:\Projets\")

End Sub

Sub TestSub(ByVal s As String)

    Debug.Print s

End Sub

Edit: Here's how you can implement this code in your workbook to achieve your objective.

Sub TestSub(ByVal s As String)

    Dim FSO As New FileSystemObject
    Dim myFolder As Folder
    Dim myFile As File

    Set myFolder = FSO.GetFolder(s)
    For Each myFile In myFolder.Files
        If myFile.Name = Range("E1").Value Then
            Debug.Print myFile.Name 'Or do whatever you want with the file
        End If
    Next

End Sub

Here, I just debug the name of the found file, the rest is up to you. ;)

Of course, some would say it's a bit clumsy to call twice the FileSystemObject so you could simply write your code like this (depends on wether you want to compartmentalize or not):

Function Recurse(sPath As String) As String

    Dim FSO As New FileSystemObject
    Dim myFolder As Folder
    Dim mySubFolder As Folder
    Dim myFile As File

    Set myFolder = FSO.GetFolder(sPath)

    For Each mySubFolder In myFolder.SubFolders
        For Each myFile In mySubFolder.Files
            If myFile.Name = Range("E1").Value Then
                Debug.Print myFile.Name & " in " & myFile.Path 'Or do whatever you want with the file
                Exit For
            End If
        Next
        Recurse = Recurse(mySubFolder.Path)
    Next

End Function

Sub TestR()

    Call Recurse("D:\Projets\")

End Sub

int *p=(int *)0x1234 = 10; //0x1234 is the memory address and value 10 is assigned in that address


unsigned int *ptr=(unsigned int *)0x903jf = 20;//0x903j is memory address and value 20 is assigned 

Basically in Embedded platform we are using directly addresses instead of names

Keeping it simple is the key.

Try Below.

var values = new int[5,7,3];
values = values.OrderBy(p => p).ToList();

robocopy seems to be the most versatile. See it's other options in the help

robocopy /?
robocopy SRC DST /E /MOV

Or, building on Rusian L.'s suggestion, if the item you're searching for can be in the list more than once::

[Extension()]
public void ReplaceAll<T>(List<T> input, T search, T replace)
{
    int i = 0;
    do {
        i = input.FindIndex(i, s => EqualityComparer<T>.Default.Equals(s, search));

        if (i > -1) {
            FileSystem.input(i) = replace;
            continue;
        }

        break;  
    } while (true);
}

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults 

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln).

Edit

At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*. Updated above code to reflect this.

Another Edit

Also as pointed out in the comments (by Charles Brandt), /filename must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.

Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

yetAnother Edit

As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.

According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering", in which case you have to pass sequence and runlevel configuration through command line arguments.

The equivalent argument set for the above example is

sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

Think like this:

class Animal { /* Some virtual members */ };
class Dog: public Animal {};
class Cat: public Animal {};


Dog     dog;
Cat     cat;
Animal& AnimalRef1 = dog;  // Notice no cast required. (Dogs and cats are animals).
Animal& AnimalRef2 = cat;
Animal* AnimalPtr1 = &dog;
Animal* AnimlaPtr2 = &cat;

Cat&    catRef1 = dynamic_cast<Cat&>(AnimalRef1);  // Throws an exception  AnimalRef1 is a dog
Cat*    catPtr1 = dynamic_cast<Cat*>(AnimalPtr1);  // Returns NULL         AnimalPtr1 is a dog
Cat&    catRef2 = dynamic_cast<Cat&>(AnimalRef2);  // Works
Cat*    catPtr2 = dynamic_cast<Cat*>(AnimalPtr2);  // Works

// This on the other hand makes no sense
// An animal object is not a cat. Therefore it can not be treated like a Cat.
Animal  a;
Cat&    catRef1 = dynamic_cast<Cat&>(a);    // Throws an exception  Its not a CAT
Cat*    catPtr1 = dynamic_cast<Cat*>(&a);   // Returns NULL         Its not a CAT.

Now looking back at your first statement:

Animal   animal = cat;    // This works. But it slices the cat part out and just
                          // assigns the animal part of the object.
Cat      bigCat = animal; // Makes no sense.
                          // An animal is not a cat!!!!!
Dog      bigDog = bigCat; // A cat is not a dog !!!!

You should very rarely ever need to use dynamic cast.
This is why we have virtual methods:

void makeNoise(Animal& animal)
{
     animal.DoNoiseMake();
}

Dog    dog;
Cat    cat;
Duck   duck;
Chicken chicken;

makeNoise(dog);
makeNoise(cat);
makeNoise(duck);
makeNoise(chicken);

The only reason I can think of is if you stored your object in a base class container:

std::vector<Animal*>  barnYard;
barnYard.push_back(&dog);
barnYard.push_back(&cat);
barnYard.push_back(&duck);
barnYard.push_back(&chicken);

Dog*  dog = dynamic_cast<Dog*>(barnYard[1]); // Note: NULL as this was the cat.

But if you need to cast particular objects back to Dogs then there is a fundamental problem in your design. You should be accessing properties via the virtual methods.

'async': false says it's depreciated. I did notice if I run console.log('test1'); on ajax success, then console.log('test2'); in normal js after the ajax function, test2 prints before test1 so the issue is an ajax call has a small delay, but doesn't stop the rest of the function to get results. The variable simply, was not set "yet", so you need to delay the next function.

function runPHP(){
    var input = document.getElementById("input1");
    var result = 'failed to run php';

    $.ajax({ url: '/test.php',
        type: 'POST',
        data: {action: 'test'},
        success: function(data) {
            result = data;
        }
    });

    setTimeout(function(){
        console.log(result);
    }, 1000);
}

on test.php (incase you need to test this function)

function test(){
    print 'ran php';
}

if(isset($_POST['action']) && !empty($_POST['action'])) {
    $action = htmlentities($_POST['action']);
    switch($action) {
        case 'test' : test();break;
    }
}

Microsoft Msdn article The Forgotten Controls: HTML Server Controls explains use of runat="server" with an example on text box <input type="text"> by converting it to <input type="text" id="Textbox1" runat="server">

Doing this will give you programmatic access to the HTML element on the server before the Web page is created and sent down to the client. The HTML element must contain an id attribute. This attribute serves as an identity for the element and enables you to program to elements by their specific IDs. In addition to this attribute, the HTML element must contain runat="server". This tells the processing server that the tag is processed on the server and is not to be considered a traditional HTML element.

In short, to enable programmatic access to the HTML element add runat="server" to it.

.toString() is available, or just add "" to the end of the int

var x = 3,
    toString = x.toString(),
    toConcat = x + "";

Angular is simply JavaScript at the core.

Connect to your server via SSH

then connect to your mysql console

and

USE user_base
REPAIR TABLE TABLE;

-OR-

If there are a lot of broken tables in current database:

mysqlcheck -uUSER -pPASSWORD  --repair --extended user_base

If there are a lot of broken tables in a lot of databases:

mysqlcheck -uUSER -pPASSWORD  --repair --extended -A

1) Also you can use lateinit If you sure do your initialization later on onCreate() or elsewhere.

Use this

lateinit var left: Node

Instead of this

var left: Node? = null

2) And there is other way that use !! end of variable when you use it like this

queue.add(left!!) // add !!

Have a look at the content by type web part - http://codeplex.com/eoffice - probably the most flexible viewing web part.

Trying to write a REST API from scratch is not a simple task. There are many issues to factor and you will need to write a lot of code to process requests and data coming from the caller, authentication, retrieval of data and sending back responses.

Your best bet is to use a framework that already has this functionality ready and tested for you.

Some suggestions are:

Phalcon - REST API building - Easy to use all in one framework with huge performance

Apigility - A one size fits all API handling framework by Zend Technologies

Laravel API Building Tutorial

and many more. Simple searches on Bitbucket/Github will give you a lot of resources to start with.

INSERT INTO mytable(col1,col2) 
    SELECT 'val1','val2' 
    WHERE NOT EXISTS (SELECT 1 FROM mytable WHERE col1='val1')

Meh too slow. Here's my example anyway :)
http://jsfiddle.net/cqDES/

$(function() {
    $('select').change(function() {
        var val = $(this).val();
        if (val) {
            $('div:not(#div' + val + ')').slideUp();
            $('#div' + val).slideDown();
        } else {
            $('div').slideDown();
        }
    });
});

      GridViewRow gvRow = new GridViewRow(0, 0, DataControlRowType.DataRow,DataControlRowState.Insert);
      for (int i = 0; i < e.Row.Cells.Count; i++)
      {
         TableCell tCell = new TableCell();
         tCell.Text = "&nbsp;";
         gvRow.Cells.Add(tCell);
         Table tbl = e.Row.Parent as Table;
         tbl.Rows.Add(gvRow);
      }
   }
}

 DateTime time = DateTime.Now;              // Use current time
 string format = "yyyy-MM-dd HH:mm:ss";    // modify the format depending upon input required in the column in database 
 string insert = @" insert into Table(DateTime Column) values ('" + time.ToString(format) + "')"; 

and execute the query. DateTime.Now is to insert current Datetime..

[1] TRUE

basically, look for everything at the beginning except _, and then the _2.

+1 to @Ananda_Mahto for suggesting grepl instead of grep.

You won't be able to send a message through other people mail servers. Check with your host provider how to send emails. Try to send an email from your server without PHP, you can use any email client like Outook. Just after it works, try to configure PHP.ini with your email client SMTP (sending e-mail) configuration.

Here is how to split one commit in IntelliJ IDEA, PyCharm, PhpStorm etc

1. In Version Control log window, select the commit you would like to split, right click and select the Interactively Rebase from Here

2. mark the one you want to split as edit, click Start Rebasing

3. You should see a yellow tag is placed meaning that the HEAD is set to that commit. Right click on that commit, select Undo Commit

4. Now those commits are back to staging area, you can then commit them separately. After all change has been committed, the old commit becomes inactive.

Add display: block;. That's the difference between a <div> tag and an <a> tag

.btn {
      display: block;
      height: 300px;
      width: 300px;
      border-radius: 50%;
      border: 1px solid red;
    }

SQLite doesn't define any particular extension for this, it's your own choice. Personally, I name them with the .sqlite extension, just so there isn't any ambiguity when I'm looking at my files later.

You could resolve the problem with:

for line in open(your_file_path, 'rb'):

'rb' is reading the file in binary mode. Read more here.

A shorter version of converting List to Array of specific type (for example Long):

Long[] myArray = myList.toArray(Long[]::new);

I'm pretty sure you should go with bar(); because with foo(); it creates a List (for nothing) since you create a new File[0] in the end anyway, so why not go with directly returning it!

The git solution for such scenarios is setting SKIP-WORKTREE BIT. Run only the following command:

git update-index --skip-worktree .classpath .gitignore

It is used when you want git to ignore changes of files that are already managed by git and exist on the index. This is a common use case for config files.

Running git rm --cached doesn't work for the scenario mentioned in the question. If I simplify the question, it says:

How to have .classpath and .project on the repo while each one can change it locally and git ignores this change?

As I commented under the accepted answer, the drawback of git rm --cached is that it causes a change in the index, so you need to commit the change and then push it to the remote repository. As a result, .classpath and .project won't be available on the repo while the PO wants them to be there so anyone that clones the repo for the first time, they can use it.

What is SKIP-WORKTREE BIT?

Based on git documentaion:

Skip-worktree bit can be defined in one (long) sentence: When reading an entry, if it is marked as skip-worktree, then Git pretends its working directory version is up to date and read the index version instead. Although this bit looks similar to assume-unchanged bit, its goal is different from assume-unchanged bit’s. Skip-worktree also takes precedence over assume-unchanged bit when both are set.

More details is available here.

You can also accomplish this using the sqldf package as shown below:

library(sqldf)

x <- read.table(text='Name     Month  Rate1     Rate2
Aira       1      12        23
                Aira       2      18        73
                Aira       3      19        45
                Ben        1      53        19
                Ben        2      22        87
                Ben        3      19        45
                Cat        1      22        87
                Cat        2      67        43
                Cat        3      45        32', header=TRUE)

sqldf("
select 
  Name
  ,avg(Rate1) as Rate1_float
  ,avg(Rate2) as Rate2_float
  ,avg(Rate1) as Rate1
  ,avg(Rate2) as Rate2
from x
group by 
  Name
")

#  Name Rate1_float Rate2_float Rate1 Rate2
#1 Aira    16.33333    47.00000    16    47
#2  Ben    31.33333    50.33333    31    50
#3  Cat    44.66667    54.00000    44    54

I am a recent convert to dplyr as shown in other answers, but sqldf is nice as most data analysts/data scientists/developers have at least some fluency in SQL. In this way, I think it tends to make for more universally readable code than dplyr or other solutions presented above.

UPDATE: In responding to the comment below, I attempted to update the code as shown above. However, the behavior was not as I expected. It seems that the column definition (i.e. int vs float) is only carried through when the column alias matches the original column name. When you specify a new name, the aggregate column is returned without rounding.

In my case I had to switch between two versions of icu4c since I still maintain PHP 5.6 projects (which use the old icu4c 64.2). brew install and reinstall from raw .rb links always replaces the previously installed versions for some reason.

#fetching 64.2

To adjust the length of the samples:

set key samplen X

(default is 4)

To adjust the vertical spacing of the samples:

set key spacing X

(default is 1.25)

and (for completeness), to adjust the fontsize:

set key font "<face>,<size>"

(default depends on the terminal)

And of course, all these can be combined into one line:

set key samplen 2 spacing .5 font ",8"

Note that you can also change the position of the key using set key at <position> or any one of the pre-defined positions (which I'll just defer to help key at this point)

Another solution within a query :

select 
    Id, 
    STUFF(
        (select (', "' + od.ProductName + '"')
        from OrderDetails od (nolock)
        where od.Order_Id = o.Id
        order by od.ProductName
        FOR XML PATH('')), 1, 2, ''
    ) ProductNames
from Orders o (nolock)
where o.Customer_Id = 525188
order by o.Id desc

(EDIT: thanks @user007 for the STUFF declaration)

In addition to previous answers there is one important for me note:

shelve is JetBrains products feature (such as WebStorm, PhpStorm, PyCharm, etc.). It puts shelved files into .idea/shelf directory.

stash is one of git options. It puts stashed files under the .git directory.

Check if "nowrap" solve the issue to an extent. Note: nowrap is not supported in HTML5

<table border="1" style="width: 100%; white-space: nowrap; table-layout: fixed;">
<tr>
    <td style="overflow: hidden; text-overflow: ellipsis;" nowrap >This cells has more content  </td>
    <td style="overflow: hidden; text-overflow: ellipsis;" nowrap >Less content here has more content</td>
</tr>

Is this the expected behavior?

the json_encode() only works with UTF-8 encoded data.

VB Code:

Dim ListItem1 As New ListItem()
ListItem1.Text = "put anything here"
ListItem1.Value = "0"
drpTag.DataBind()
drpTag.Items.Insert(0, ListItem1)

  ValueToCompare="0">
</asp:CompareValidator>

The docs indicate that numpy.correlate is not what you are looking for:

numpy.correlate(a, v, mode='valid', old_behavior=False)[source]
  Cross-correlation of two 1-dimensional sequences.
  This function computes the correlation as generally defined in signal processing texts:
     z[k] = sum_n a[n] * conj(v[n+k])
  with a and v sequences being zero-padded where necessary and conj being the conjugate.

Instead, as the other comments suggested, you are looking for a Pearson correlation coefficient. To do this with scipy try:

from scipy.stats.stats import pearsonr   
a = [1,4,6]
b = [1,2,3]   
print pearsonr(a,b)

This gives

(0.99339926779878274, 0.073186395040328034)

You can also use numpy.corrcoef:

import numpy
print numpy.corrcoef(a,b)

This gives:

[[ 1.          0.99339927]
 [ 0.99339927  1.        ]]

List<ProjectResources> list = new List<ProjectResources>();        
IList<ProjectResources> obj = `Your Data Will Be Here`;
list = obj.ToList<ProjectResources>();

This Would Convert IList Object to List Object.

It is all about the namespace declaration. According to http://php.net/manual/en/language.namespaces.definition.php all namespace declaration must be put on the very top of the file after the <?php opening php tag. This means that before writing any code on the file, if that file needs to be contained in a namespace then you must first declare the namespace before writing any code. Like this:

<?php
namespace App\Suport\Facades;

class AuthUser {
  // methods and more codes
}

BUT the declare keyword can be put before the namespace declaration so this is still valid:

<?php
declare(maxTries = 3);

namespace App\Suport\Facades;

class AuthUser {
  // methods and more codes
}

all other stuff must be put AFTER the namespace keyword. For more info, read the http://php.net/manual/en/language.namespaces.definition.php.

This is similar to the comment from @siwei-shen but you need the -o flag to do multiple patterns. The -o flag stands for 'or'

find . -type f -not -name '*ignore1' -o -not -name '*ignore2' | xargs rm

I thought uninstalling the app by dragging its icon to "Uninstall" would solve the problem, but it did not.

Here is what solved the problem:

1. Go to Settings
2. Choose Apps
3. Find your app (yes I was surprised to still find it here!) and press it
4. In the top-right, press the 3 dots
5. Select "Uninstall for all users"

Try again, it should work now.

Best practice: one form per product is definitely the way to go.

Benefits:

• It will save you the hassle of having to parse the data to figure out which product was clicked
• It will reduce the size of data being posted

In your specific situation

If you only ever intend to have one form element, in this case a submit button, one form for all should work just fine.

My recommendation Do one form per product, and change your markup to something like:

<form method="post" action="">
    <input type="hidden" name="product_id" value="123">
    <button type="submit" name="action" value="add_to_cart">Add to Cart</button>
</form>

This will give you a much cleaner and usable POST. No parsing. And it will allow you to add more parameters in the future (size, color, quantity, etc).

Note: There's no technical benefit to using <button> vs. <input>, but as a programmer I find it cooler to work with action=='add_to_cart' than action=='Add to Cart'. Besides, I hate mixing presentation with logic. If one day you decide that it makes more sense for the button to say "Add" or if you want to use different languages, you could do so freely without having to worry about your back-end code.

The Bundle is a container for all the information you want to save. You use the put* functions to insert data into it. Here's a short list (there are more) of put functions you can use to store data in the Bundle.

putString
putBoolean
putByte
putChar
putFloat
putLong
putShort
putParcelable (used for objects but they must implement Parcelable)

In your onCreate function, this Bundle is handed back to the program. The best way to check if the application is being reloaded, or started for the first time is:

if (savedInstanceState != null) {
    // Then the application is being reloaded
}

To get the data back out, use the get* functions just like the put* functions. The data is stored as a name-value pair. This is like a hashmap. You provide a key and the value, then when you want the value back, you give the key and the function gets the value. Here's a short example.

@Override
public void onSaveInstanceState(Bundle outState) {
   outState.putString("message", "This is my message to be reloaded");
   super.onSaveInstanceState(outState);
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (savedInstanceState != null) {
        String message = savedInstanceState.getString("message");
        Toast.makeText(this, message, Toast.LENGTH_LONG).show();
    }
}

Your saved message will be toasted to the screen. Hope this helps.

You could do it with a static import and a helper class

nb the generification of this class could probably be improved

public class Lists {

   private Lists() { } // can't be instantiated

   public static List<T> join(List<T>... lists) {
      List<T> result = new ArrayList<T>();
      for(List<T> list : lists) {
         result.addAll(list);
      }
      return results;
   }

}

Then you can do things like

import static Lists.join;
List<T> result = join(list1, list2, list3, list4);

You can call sortable on a <tbody> instead of on the individual rows.

<table>
    <tbody>
        <tr> 
            <td>1</td>
            <td>2</td>
        </tr>
        <tr>
            <td>3</td>
            <td>4</td> 
        </tr>
        <tr>
            <td>5</td>
            <td>6</td>

The XMLHttpRequest.timeout property represents a number of milliseconds a request can take before automatically being terminated. The default value is 0, which means there is no timeout. An important note the timeout shouldn't be used for synchronous XMLHttpRequests requests, used in a document environment or it will throw an InvalidAccessError exception. You may not use a timeout for synchronous requests with an owning window.

IE10 and 11 do not support synchronous requests, with support being phased out in other browsers too. This is due to detrimental effects resulting from making them.

There is the 99% solution to get bak file from remote sql server to your local pc. I described it there in my post http://www.ok.unsode.com/post/2015/06/27/remote-sql-backup-to-local-pc

In general it will look like this:

• execute sql script to generate bak files

• execute sql script to insert each bak file into temp table with varbinary field type and select this row and download data

• repeat prev. step as many time as you have bak files

• execute sql script to remove all temporary resources

that's it, you have your bak files on your local pc.

$('#cloneDiv').click(function(){


  // get the last DIV which ID starts with ^= "klon"
  var $div = $('div[id^="klon"]:last');

  // Read the Number from that DIV's ID (i.e: 3 from "klon3")
  // And increment that number by 1
  var num = parseInt( $div.prop("id").match(/\d+/g), 10 ) +1;

  // Clone it and assign the new ID (i.e: from num 4 to ID "klon4")
  var $klon = $div.clone().prop('id', 'klon'+num );

  // Finally insert $klon wherever you want
  $div.after( $klon.text('klon'+num) );

});

By default, the docker daemon will use the unix socket unix:///var/run/docker.sock (you can check this is the case for you by doing a sudo netstat -tunlp and note that there is no docker daemon process listening on any ports). It's recommended to keep this setting for security reasons but it sounds like Riak requires the daemon to be running on a TCP socket.

To start the docker daemon with a TCP socket that anybody can connect to, use the -H option:

sudo docker -H 0.0.0.0:2375 -d &

Warning: This means machines that can talk to the daemon through that TCP socket can get root access to your host machine.

Unfortunately there is not cross browser JavaScript support for trim().

If you aren't using jQuery (which has a .trim() method) you can use the following methods to add trim support to strings:

String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g,"");
}
String.prototype.ltrim = function() {
    return this.replace(/^\s+/,"");
}
String.prototype.rtrim = function() {
    return this.replace(/\s+$/,"");
}

Use functools.partial, not lambdas! And ofc Perform is a useless function, you can pass around functions directly.

for func in [Action1, partial(Action2, p), partial(Action3, p, r)]:
  func()

It can be done through "Import/Export Data..." in SQL Server Management Studio

I believe python arrays just admit values. So convert it to list:

kOUT = np.zeros(N+1)
kOUT = kOUT.tolist()

From the answer here, spark.sql.shuffle.partitions configures the number of partitions that are used when shuffling data for joins or aggregations.

spark.default.parallelism is the default number of partitions in RDDs returned by transformations like join, reduceByKey, and parallelize when not set explicitly by the user. Note that spark.default.parallelism seems to only be working for raw RDD and is ignored when working with dataframes.

If the task you are performing is not a join or aggregation and you are working with dataframes then setting these will not have any effect. You could, however, set the number of partitions yourself by calling df.repartition(numOfPartitions) (don't forget to assign it to a new val) in your code.

To change the settings in your code you can simply do:

sqlContext.setConf("spark.sql.shuffle.partitions", "300")
sqlContext.setConf("spark.default.parallelism", "300")

Alternatively, you can make the change when submitting the job to a cluster with spark-submit:

./bin/spark-submit --conf spark.sql.shuffle.partitions=300 --conf spark.default.parallelism=300

There is a trade off the C designers have made. That's to say, they made the decision to put speed above safety. C won't

• Check array index bounds
• Check for uninitialized variable values
• Check for memory leaks
• Check for null pointer dereference

When you index into an array, in Java it takes some method call in the virtual machine, bound checking and other sanity checks. That is valid and absolutely fine, because it adds safety where it's due. But in C, even pretty trivial things are not put in safety. For example, C doesn't require memcpy to check whether the regions to copy overlap. It's not designed as a language to program a big business application.

But these design decisions are not bugs in the C language. They are by design, as it allows compilers and library writers to get every bit of performance out of the computer. Here is the spirit of C how the C Rationale document explains it:

C code can be non-portable. Although it strove to give programmers the opportunity to write truly portable programs, the Committee did not want to force programmers into writing portably, to preclude the use of C as a ``high-level assembler'': the ability to write machine-specific code is one of the strengths of C.

Keep the spirit of C. The Committee kept as a major goal to preserve the traditional spirit of C. There are many facets of the spirit of C, but the essence is a community sentiment of the underlying principles upon which the C language is based. Some of the facets of the spirit of C can be summarized in phrases like

• Trust the programmer.
• Don't prevent the programmer from doing what needs to be done.
• Keep the language small and simple.
• Provide only one way to do an operation.
• Make it fast, even if it is not guaranteed to be portable.

The last proverb needs a little explanation. The potential for efficient code generation is one of the most important strengths of C. To help ensure that no code explosion occurs for what appears to be a very simple operation, many operations are defined to be how the target machine's hardware does it rather than by a general abstract rule. An example of this willingness to live with what the machine does can be seen in the rules that govern the widening of char objects for use in expressions: whether the values of char objects widen to signed or unsigned quantities typically depends on which byte operation is more efficient on the target machine.

• Binary search tree: when inorder traversal is made on binary tree, you get sorted values of inserted items
• Binary tree: no sorted order is found in any kind of traversal

Just tried this solution, we don't have to even write int.

int[][] twoDim = { { 1, 2 }, { 3, 7 }, { 8, 9 }, { 4, 2 }, { 5, 3 } };
Arrays.sort(twoDim, (a1,a2) -> a2[0] - a1[0]);

This thing will also work, it automatically detects the type of string.

I had a similar problem. I am posting my solution here because I believe it might help one of the commenters.

For me, the obstacle was that the page required a login and then gave me a new URL through javascript. Here is what I had to do:

curl -c cookiejar -g -O -J -L -F "j_username=username" -F "j_password=password" <URL>

Note that j_username and j_password is the name of the fields for my website's login form. You will have to open the source of the webpage to see what the 'name' of the username field and the 'name' of the password field is in your case. After that I go an html file with java script in which the new URL was embedded. After parsing this out just resubmit with the new URL:

curl -c cookiejar -g -O -J -L -F "j_username=username" -F "j_password=password" <NEWURL>

Comma-separated items enclosed by ( and ) are tuples, those enclosed by [ and ] are lists.

"\n" is the linefeed character. It means end the present line and go to a new line for anyone who is reading it.

This is, imo, the most elegant way to do it (with ES6). Instantiate you empty array with 7 indexes and map in one line:

Array.apply(null, Array(7)).map((i)=>
<Somecomponent/>
)

Ok...so first you need to import the image into your project.

1) Select the PictureBox in the Form Design View

2) Open PictureBox Tasks
(it's the little arrow printed to right on the edge of the PictureBox)

3) Click on "Choose image..."

4) Select the second option "Project resource file:"
(this option will create a folder called "Resources" which you can access with Properties.Resources)

5) Click on "Import..." and select your image from your computer
(now a copy of the image will be saved in "Resources" folder created at step 4)

6) Click on "OK"

Now the image is in your project and you can use it with the Properties command. Just type this code when you want to change the picture in the PictureBox:

pictureBox1.Image = Properties.Resources.MyImage;

Note:
MyImage represent the name of the image...
After typing "Properties.Resources.", all imported image files are displayed...

NoClassDefFoundError doesn't give much of a clue as to what went wrong inside the static block. It is good practice to always have a block like this inside of static { ... } initialization code:

static {
  try {

    ... your init code here

  } catch (Throwable t) {
    LOG.error("Failure during static initialization", t);
    throw t;
  }
}

Best /Fastest way to read an Excel Sheet into a DataTable?

Yet another approach is ISNULL().

UPDATE [DATABASE].[dbo].[TABLE_NAME]
SET    
    [ABC]  = ISNULL(@ABC, [ABC]),
    [ABCD] = ISNULL(@ABCD, [ABCD])

The difference between ISNULL and COALESCE is the return type. COALESCE can also take more than 2 arguments, and use the first that is not null. I.e.

select COALESCE(null, null, 1, 'two') --returns 1
select COALESCE(null, null, null, 'two') --returns 'two'

In the end you have to implement this around Enum.GetNames:

public bool TryParseEnum<T>(string str, bool caseSensitive, out T value) where T : struct {
    // Can't make this a type constraint...
    if (!typeof(T).IsEnum) {
        throw new ArgumentException("Type parameter must be an enum");
    }
    var names = Enum.GetNames(typeof(T));
    value = (Enum.GetValues(typeof(T)) as T[])[0];  // For want of a better default
    foreach (var name in names) {
        if (String.Equals(name, str, caseSensitive ? StringComparison.Ordinal : StringComparison.OrdinalIgnoreCase)) {
            value = (T)Enum.Parse(typeof(T), name);
            return true;
        }
    }
    return false;
}

Additional notes:

• Enum.TryParse is included in .NET 4. See here http://msdn.microsoft.com/library/dd991876(VS.100).aspx
• Another approach would be to directly wrap Enum.Parse catching the exception thrown when it fails. This could be faster when a match is found, but will likely to slower if not. Depending on the data you are processing this may or may not be a net improvement.

EDIT: Just seen a better implementation on this, which caches the necessary information: http://damieng.com/blog/2010/10/17/enums-better-syntax-improved-performance-and-tryparse-in-net-3-5

I was looking at this problem just now and found this solution. If your RowSource points to a range of cells, the column headings in a multi-column listbox are taken from the cells immediately above the RowSource.

Using the example pictured here, inside the listbox, the words Symbol and Name appear as title headings. When I changed the word Name in cell AB1, then opened the form in the VBE again, the column headings changed.

The example came from a workbook in VBA For Modelers by S. Christian Albright, and I was trying to figure out how he got the column headings in his listbox :)

It should be legal to put a semicolon directly before the WITH keyword.

functionName() : ReturnType { ... }

The answer is simpler than people are making it.

There's no technical advantage either way, and "x is not y" is what everybody else uses, which makes it the clear winner. It doesn't matter that it "looks more like English" or not; everyone uses it, which means every user of Python--even Chinese users, whose language Python looks nothing like--will understand it at a glance, where the slightly less common syntax will take a couple extra brain cycles to parse.

Don't be different just for the sake of being different, at least in this field.

window.onload will work like this:

function codeAddress() {_x000D_
 document.getElementById("test").innerHTML=Date();_x000D_
}_x000D_
window.onload = codeAddress;

If you have this problem in Windows 10, and you know you have premisions on folder (You could write before but it just started to print exception PermissionError recently).. You will need to install Windows updates... I hope someone will help this info.

A simple example in shell script

#!/bin/bash

current_date_time="`date +%Y%m%d%H%M%S`";
echo $current_date_time;

With out punctuation format :- +%Y%m%d%H%M%S
With punctuation :- +%Y-%m-%d %H:%M:%S

Felix Kling's way will work, (actually beat me to the punch), but I was also going to suggest to use

$('#next').die().live('click', stopMoving);

this might be a better way to do it if you run into problems and strange behaviors when the element is clicked multiple times.

If you own the class better go with Comparable. Generally Comparator is used if you dont own the class but you have to use it a TreeSet or TreeMap because Comparator can be passed as a parameter in the conctructor of TreeSet or TreeMap. You can see how to use Comparator and Comparable in http://preciselyconcise.com/java/collections/g_comparator.php

Looking for EventHandling, ActionListener?

or code?

JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
        textfield.setText("");
        //textfield.setText(null); //or use this
    }
});

How to Use Buttons

you can also do something more specific like that based on Anthony Artemiew's response:

<View style={globalStyles.searchSection}>
                    <TextInput
                        style={globalStyles.input}
                        placeholder="Rechercher"
                        onChangeText={(searchString) => 
                       {this.setState({searchString})}}
                        underlineColorAndroid="transparent"
                    />
                     <Ionicons onPress={()=>console.log('Recherche en cours...')} style={globalStyles.searchIcon} name="ios-search" size={30} color="#1764A5"/>

 </View>

Style:

 searchSection: {
        flexDirection: 'row',
        justifyContent: 'center',
        alignItems: 'center',
        backgroundColor: '#fff',
        borderRadius:50,
        marginLeft:35,
        width:340,
        height:40,
        margin:25
    },
    searchIcon: {
        padding: 10,
    },
    input: {
        flex: 1,
        paddingTop: 10,
        paddingRight: 10,
        paddingBottom: 10,
        paddingLeft: 0,
        marginLeft:10,
        borderTopLeftRadius:50,
        borderBottomLeftRadius:50,
        backgroundColor: '#fff',
        color: '#424242',
    },

This is bcrypt:

Generate a random salt. A "cost" factor has been pre-configured. Collect a password.

Derive an encryption key from the password using the salt and cost factor. Use it to encrypt a well-known string. Store the cost, salt, and cipher text. Because these three elements have a known length, it's easy to concatenate them and store them in a single field, yet be able to split them apart later.

When someone tries to authenticate, retrieve the stored cost and salt. Derive a key from the input password, cost and salt. Encrypt the same well-known string. If the generated cipher text matches the stored cipher text, the password is a match.

Bcrypt operates in a very similar manner to more traditional schemes based on algorithms like PBKDF2. The main difference is its use of a derived key to encrypt known plain text; other schemes (reasonably) assume the key derivation function is irreversible, and store the derived key directly.

Stored in the database, a bcrypt "hash" might look something like this:

$2a$10$vI8aWBnW3fID.ZQ4/zo1G.q1lRps.9cGLcZEiGDMVr5yUP1KUOYTa

This is actually three fields, delimited by "$":

• 2a identifies the bcrypt algorithm version that was used.
• 10 is the cost factor; 2¹⁰ iterations of the key derivation function are used (which is not enough, by the way. I'd recommend a cost of 12 or more.)
• vI8aWBnW3fID.ZQ4/zo1G.q1lRps.9cGLcZEiGDMVr5yUP1KUOYTa is the salt and the cipher text, concatenated and encoded in a modified Base-64. The first 22 characters decode to a 16-byte value for the salt. The remaining characters are cipher text to be compared for authentication.

This example is taken from the documentation for Coda Hale's ruby implementation.

The best way is to set up Apache and to set the access through it. Check the svn book for help. If you don't want to use Apache, you can also do minimalistic access control using svnserve.

This is by far the easiest way I have found to use javascript regex to check phone number format. this particular example checks if it is a 10 digit number.

<input name="phone" pattern="^\d{10}$" type="text" size="50">

The input field gets flagged when submit button is clicked if the pattern doesn't match the value, no other css or js required.

Use this code to pass arraylist<customobj> to anthother Activity

firstly serialize our contact bean

public class ContactBean implements Serializable {
      //do intialization here
}

Now pass your arraylist

 Intent intent = new Intent(this,name of activity.class);
 contactBean=(ConactBean)_arraylist.get(position);
 intent.putExtra("contactBeanObj",conactBean);
 _activity.startActivity(intent);

Since this is an open-ended question, I will just give you an idea of how I would go about implementing something like this myself.

<span class="inputname">
    Project Images:
    <a href="#" class="add_project_file">
        <img src="images/add_small.gif" border="0" />
    </a>
</span>

<ul class="project_images">
    <li><input name="upload_project_images[]" type="file" /></li>
</ul>

Wrapping the file inputs inside li elements allows to easily remove the parent of our 'remove' links when clicked. The jQuery to do so is close to what you have already:

// Add new input with associated 'remove' link when 'add' button is clicked.
$('.add_project_file').click(function(e) {
    e.preventDefault();

    $(".project_images").append(
        '<li>'
      + '<input name="upload_project_images[]" type="file" class="new_project_image" /> '
      + '<a href="#" class="remove_project_file" border="2"><img src="images/delete.gif" /></a>'
      + '</li>');
});

// Remove parent of 'remove' link when link is clicked.
$('.project_images').on('click', '.remove_project_file', function(e) {
    e.preventDefault();

    $(this).parent().remove();
});

If you have a pandas dataframe and want to preserve the dtypes, even the categoricals, this is a fast way to do it:

import numpy as np
import pandas as pd
df = pd.DataFrame({1: [1, 2, 3], 2: [4, 5, 6]})
number_repeats = 50
new_df = df.reindex(np.tile(df.index, number_repeats))

The rem command is indeed for comments. It doesn't inherently update anyone after running the script. Some script authors might use it that way instead of echo, though, because by default the batch interpreter will print out each command before it's processed. Since rem commands don't do anything, it's safe to print them without side effects. To avoid printing a command, prefix it with @, or, to apply that setting throughout the program, run @echo off. (It's echo off to avoid printing further commands; the @ is to avoid printing that command prior to the echo setting taking effect.)

So, in your batch file, you might use this:

@echo off
REM To skip the following Python commands, put "REM" before them:
python foo.py
python bar.py

At my work we have our restful services on a different port number and the data resides in db2 on a pair of AS400s. We typically use the $.getJSON AJAX method because it easily returns JSONP using the ?callback=? without having any issues with CORS.

data ='USER=<?echo trim($USER)?>' +
         '&QRYTYPE=' + $("input[name=QRYTYPE]:checked").val();

        //Call the REST program/method returns: JSONP 
        $.getJSON( "http://www.stackoverflow.com/rest/resttest?callback=?",data)
        .done(function( json ) {        

              //  loading...
                if ($.trim(json.ERROR) != '') {
                    $("#error-msg").text(message).show();
                }
                else{
                    $(".error").hide();
                    $("#jsonp").text(json.whatever);

                }

        })  
        .fail(function( jqXHR, textStatus, error ) {
        var err = textStatus + ", " + error;
        alert('Unable to Connect to Server.\n Try again Later.\n Request Failed: ' + err);
        });     

Try with Contains function;

Determines whether a sequence contains a specified element.

var allowedStatus = new[]{ "A", "B", "C" };
var filteredOrders = orders.Order.Where(o => allowedStatus.Contains(o.StatusCode));

If you've already committed a bunch of unwanted files, you can unstage them and tell git to mark them as deleted (without actually deleting them) with

git rm --cached -r .

--cached tells it to remove the paths from staging and the index without removing the files themselves and -r operates on directories recursively. You can then git add any files that you want to keep tracking.

You can use a Split :

$text = "test.txt ; 131 136 80 89 119 17 60 123 210 121 188 42 136 200 131 198"
$separator = ";" # you can put many separator like this "; : ,"

$parts = $text.split($separator)

echo $parts[0] # return test.txt
echo $parts[1] # return the part after the separator

This gets parent if it is a div. Then it gets class.

var div = $(this).parent("div");
var _class = div.attr("class");

Try this code:

$('.Classname').click(function(){
    $("html, body").animate({ scrollTop: 0 }, 600);
    return false;
});

I would like to share 2 tips: (tip 1) create a csv file (tip 2) Load rows from a csv file into a table.

====[ (tip 1) SQLPLUS to create a csv file form an Oracle table ]====

I use SQLPLUS with the following commands:

set markup csv on
set lines 1000
set pagesize 100000 linesize 1000
set feedback off 
set trimspool on
spool /MyFolderAndFilename.csv
Select *  from MYschema.MYTABLE  where MyWhereConditions ;
spool off
exit

====[tip 2 SQLLDR to load a csv file into a table ]====

I use SQLLDR and a csv ( comma separated ) file to add (APPEND) rows form the csv file to a table. the file has , between fields text fields have " before and after the text CRITICAL: if last column is null there is a , at the end of the line

Example of data lines in the csv file:

11,"aa",1001
22,"bb',2002
33,"cc",
44,"dd",4004
55,"ee',

This is the control file:

LOAD DATA
APPEND 
INTO TABLE MYSCHEMA.MYTABLE
fields terminated by ',' optionally enclosed by '"'
TRAILING NULLCOLS
(
CoulmnName1,
CoulmnName2,
CoulmnName3
)

This is the command to execute sqlldr in Linux. If you run in Windows use \ instead of / c:

sqlldr userid=MyOracleUser/MyOraclePassword@MyOracleServerIPaddress:port/MyOracleSIDorService  DATA=datafile.csv  CONTROL=controlfile.ctl  LOG=logfile.log  BAD=notloadedrows.bad

Good luck !

I have tried every method mentioned above and nothing worked, except installing jupyter in the new environment.

to activate the new environment conda activate new_env replace 'new_env' with your environment name.

next install jupyter 'pip install jupyter'

you can also install jupyter by going to anaconda navigator and selecting the right environment, and installing jupyter notebook from Home tab

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.

I used CountIf below, but there is lots of different ways to check existence of a value in a range.

Public Sub test()

Dim rng As Range
Dim aNumber As Long

aNumber = 666

Set rng = Sheet5.Range("B16:B615")

    If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then

        rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)

    Else
        MsgBox aNumber & " does not exist in range " & rng.Address
    End If

End Sub

ALTERNATIVE WAY

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Long

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    If Not IsError(Application.Match(aNumber, rng, 0)) Then
        rowNum = Application.Match(aNumber, rng, 0)
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

OR

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Variant

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    rowNum = Application.Match(aNumber, rng, 0)

    If Not IsError(rowNum) Then
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

You probably have as much already, but I think this is what you are trying to do:

from __future__ import with_statement
import re, os

profile = ""

os.system('wget --no-cookies --header "Cookie: soba=(SeCreTCODe)" http://stackoverflow.com/users/30/myProfile.html')
with open("myProfile.html") as f:
    for line in f:
        profile = profile + line
f.close()
p = re.compile('summarycount">(\d+)</div>') #Rep is found here
print p
m = p.search(profile)
print m
print m.group(1)
os.system("espeak \"Rep is at " + m.group(1) + " points\""
os.remove("myProfile.html")

Sometimes it happens if you either:

1. Clean solution/build or,
2. Rebuild solution/build.

If it 'suddenly' happens after such, and your code has build-time errors then try fixing those errors first.

What happens is that as your solution is built, DLL files are created and stored in the projects bin folder. If there is an error in your code during build-time, the DLL files aren't created properly which brings up an error.

A 'quick fix' would be to fix all your errors or comment them out (if they wont affect other web pages.) then rebuild project/solution

If this doesn't work then try changing: CodeBehind="blahblahblah.aspx.cs"

to: CodeFile="blahblahblah.aspx.cs"

Note: Change "blahblahblah" to the pages real name.

Using canvas we could calculate the elements width:

function getTextWidth(text, fontSize, fontName) {
  let canvas = document.createElement('canvas');
  let context = canvas.getContext('2d');
  context.font = fontSize + fontName;
  return context.measureText(text).width;
}

and use it on the chosen event:

function onChange(e) {
  let width = getTextWidth(this.value, $(this).css('font-size'), 
  $(this).css('font-family'));
  $(this.input).css('width', width);
}

Add validation groups for your validator elements. This allows you distinguish between different groups which to include in validation. Add validation group also to your submit button

This can be done for a normal subview inside a larger UIView, but it doesn't work automatically for headerViews. The height of a headerView is determined by what's returned by tableView:heightForHeaderInSection: so you have to calculate the height based on the height of the UILabel plus space for the UIButton and any padding you need. You need to do something like this:

-(CGFloat)tableView:(UITableView *)tableView 
          heightForHeaderInSection:(NSInteger)section {
    NSString *s = self.headeString[indexPath.section];
    CGSize size = [s sizeWithFont:[UIFont systemFontOfSize:17] 
                constrainedToSize:CGSizeMake(281, CGFLOAT_MAX)
                    lineBreakMode:NSLineBreakByWordWrapping];
    return size.height + 60;
}

Here headerString is whatever string you want to populate the UILabel, and the 281 number is the width of the UILabel (as setup in Interface Builder)

Found the solution as below.... posting it as it could help somebody else too :)

DateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Date date = format.parse("2014-04-24 11:15:00");

GregorianCalendar cal = new GregorianCalendar();
cal.setTime(date);

XMLGregorianCalendar xmlGregCal =  DatatypeFactory.newInstance().newXMLGregorianCalendar(cal);

System.out.println(xmlGregCal);

Output:

2014-04-24T11:15:00.000+02:00

JavaScript is a "messy" language but god help me I love it.

Alternate solution of the values check

//Duplicate Title Entry 
    $.each(ar , function (i, val) {
        if ( jQuery("input:first").val()== val) alert('VALUE FOUND'+Valuecheck);
  });

I actually found it's better for my sanity to have user preferences to be defined like so:

"translate_tabs_to_spaces": true,
"tab_size": 2,
"indent_to_bracket": true,
"detect_indentation": false

The detect_indentation: false is especially important, as it forces Sublime to honor these settings in every file, as opposed to the View -> Indentation settings.

If you want to get fancy, you can also define a keyboard shortcut to automatically re-indent your code (YMMV) by pasting the following in Sublime -> Preferences -> Key Binding - User:

[
  { "keys": ["ctrl+i"], "command": "reindent" }
]

and to visualize the whitespace:

"indent_guide_options": ["draw_active"],
"trim_trailing_white_space_on_save": true,
"ensure_newline_at_eof_on_save": true,
"draw_white_space": "all",
"rulers": [120],

Use the NotificationManager to cancel your notification. You only need to provide your notification id

mNotificationManager.cancel(YOUR_NOTIFICATION_ID);

The function has to be declared before it's getting called. This could be done in various ways:

• Write down the prototype in a header
  Use this if the function shall be callable from several source files. Just write your prototype
  int Fibonacci(int number);
  down in a .h file (e.g. myfunctions.h) and then #include "myfunctions.h" in the C code.

• Move the function before it's getting called the first time
  This means, write down the function
  int Fibonacci(int number){..}
  before your main() function

• Explicitly declare the function before it's getting called the first time
  This is the combination of the above flavors: type the prototype of the function in the C file before your main() function

As an additional note: if the function int Fibonacci(int number) shall only be used in the file where it's implemented, it shall be declared static, so that it's only visible in that translation unit.

The push div should go right after the wrap, NOT within.. just like this

<div id="wrap">
  *content goes here*
</div>

<div id="push">
</div>

<div id="footer">
  <div class="container credit">
  </div>
  <div class="container">
    <p class="muted credit">© Your Page 2013</p>
  </div>
</div>

Using null is fine for one of the branches of a ternary expression. And a ternary expression is fine as a statement in Javascript.

As a matter of style, though, if you have in mind invoking a procedure, it's clearer to write this using if..else:

if (x==2) doSomething;
else doSomethingElse

or, in your case,

if (x==2) doSomething;

First of all the itertools module is incredibly useful for all sorts of cases in which an iterator would be useful, but here is all you need to create an iterator in python:

yield

Isn't that cool? Yield can be used to replace a normal return in a function. It returns the object just the same, but instead of destroying state and exiting, it saves state for when you want to execute the next iteration. Here is an example of it in action pulled directly from the itertools function list:

def count(n=0):
    while True:
        yield n
        n += 1

As stated in the functions description (it's the count() function from the itertools module...) , it produces an iterator that returns consecutive integers starting with n.

Generator expressions are a whole other can of worms (awesome worms!). They may be used in place of a List Comprehension to save memory (list comprehensions create a list in memory that is destroyed after use if not assigned to a variable, but generator expressions can create a Generator Object... which is a fancy way of saying Iterator). Here is an example of a generator expression definition:

gen = (n for n in xrange(0,11))

This is very similar to our iterator definition above except the full range is predetermined to be between 0 and 10.

I just found xrange() (suprised I hadn't seen it before...) and added it to the above example. xrange() is an iterable version of range() which has the advantage of not prebuilding the list. It would be very useful if you had a giant corpus of data to iterate over and only had so much memory to do it in.

I asked this same question: How can I get the button that caused the submit from the form submit event?

I ended up coming up with this solution and it worked pretty well:

$(document).ready(function() {
    $("form").submit(function() { 
        var val = $("input[type=submit][clicked=true]").val();
        // DO WORK
    });
    $("form input[type=submit]").click(function() {
        $("input[type=submit]", $(this).parents("form")).removeAttr("clicked");
        $(this).attr("clicked", "true");
    });
});

In your case with multiple forms you may need to tweak this a bit but it should still apply

You can check if it can be converted to decimal. If yes, then its a number

from decimal import Decimal

def is_number(value):
    try:
        value = Decimal(value)
        return True
    except:
        return False

print is_number(None)   // False
print is_number(0)      // True
print is_number(2.3)    // True
print is_number('2.3')  // True (caveat!)

         <body>
         <marquee direction="left" behavior=scroll scrollamount="2">This is basic example of marquee</marquee>
         <marquee direction="up">The direction of text will be from bottom to top.</marquee>
         </body>

use scrollamount to control speed..

You can add an undecorated JDialog like this:

import java.awt.event.*;

import javax.swing.*;

public class TestSwing {
  public static void main(String[] args) throws Exception {
    JFrame frame = new JFrame("Parent");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(800, 600);
    frame.setVisible(true);

    final JDialog dialog = new JDialog(frame, "Child", true);    
    dialog.setSize(300, 200);
    dialog.setLocationRelativeTo(frame);
    JButton button = new JButton("Button");
    button.addActionListener(new ActionListener() {
      @Override
      public void actionPerformed(ActionEvent e) {
        dialog.dispose();
      }
    });
    dialog.add(button);
    dialog.setUndecorated(true);
    dialog.setVisible(true);
  }
}

As csgillespie said. stringsAsFactors is default on TRUE, which converts any text to a factor. So even after deleting the text, you still have a factor in your dataframe.

Now regarding the conversion, there's a more optimal way to do so. So I put it here as a reference :

> x <- factor(sample(4:8,10,replace=T))
> x
 [1] 6 4 8 6 7 6 8 5 8 4
Levels: 4 5 6 7 8
> as.numeric(levels(x))[x]
 [1] 6 4 8 6 7 6 8 5 8 4

To show it works.

The timings :

> x <- factor(sample(4:8,500000,replace=T))
> system.time(as.numeric(as.character(x)))
   user  system elapsed 
   0.11    0.00    0.11 
> system.time(as.numeric(levels(x))[x])
   user  system elapsed 
      0       0       0 

It's a big improvement, but not always a bottleneck. It gets important however if you have a big dataframe and a lot of columns to convert.

If you want the #header to be the same width as your container, with 10px of padding, you can leave out its width declaration. That will cause it to implicitly take up its entire parent's width (since a div is by default a block level element).

Then, since you haven't defined a width on it, the 10px of padding will be properly applied inside the element, rather than adding to its width:

#container {
    position: relative;
    width: 80%;
}

#header {
    position: relative;
    height: 50px;
    padding: 10px;
}

You can see it in action here.

The key when using percentage widths and pixel padding/margins is not to define them on the same element (if you want to accurately control the size). Apply the percentage width to the parent and then the pixel padding/margin to a display: block child with no width set.

Update

Another option for dealing with this is to use the box-sizing CSS rule:

#container { 
    -webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
    -moz-box-sizing: border-box;    /* Firefox, other Gecko */
    box-sizing: border-box;         /* Opera/IE 8+ */

    /* Since this element now uses border-box sizing, the 10px of horizontal
       padding will be drawn inside the 80% width */
    width: 80%;
    padding: 0 10px;
}

Here's a post talking about how box-sizing works.

change 80 to 81 and 443 to 444 by clicking config button and editing httpd.conf and httpd-ssl.congf. Now you can Access XAMPP from 127.0.0.1:81

A general purpose way is to coerce the collation to DATABASE_DEFAULT. This removes hardcoding the collation name which could change.

It's also useful for temp table and table variables, and where you may not know the server collation (eg you are a vendor placing your system on the customer's server)

select
    sone_field collate DATABASE_DEFAULT
from
    table_1
    inner join
    table_2 on table_1.field collate DATABASE_DEFAULT = table_2.field
where whatever

Short answer: it's closely related to the Content-Security-Policy: upgrade-insecure-requests response header, indicating that the browser supports it (and in fact prefers it).

It took me 30mins of Googling, but I finally found it buried in the W3 spec.

The confusion comes because the header in the spec was HTTPS: 1, and this is how Chromium implemented it, but after this broke lots of websites that were poorly coded (particularly WordPress and WooCommerce) the Chromium team apologized:

"I apologize for the breakage; I apparently underestimated the impact based on the feedback during dev and beta."
— Mike West, in Chrome Issue 501842

Their fix was to rename it to Upgrade-Insecure-Requests: 1, and the spec has since been updated to match.

Anyway, here is the explanation from the W3 spec (as it appeared at the time)...

The HTTPS HTTP request header field sends a signal to the server expressing the client’s preference for an encrypted and authenticated response, and that it can successfully handle the upgrade-insecure-requests directive in order to make that preference as seamless as possible to provide.

...

When a server encounters this preference in an HTTP request’s headers, it SHOULD redirect the user to a potentially secure representation of the resource being requested.

When a server encounters this preference in an HTTPS request’s headers, it SHOULD include a Strict-Transport-Security header in the response if the request’s host is HSTS-safe or conditionally HSTS-safe [RFC6797].

You need to initialize errorSoon, as indicated by the error message, you have only declared it.

String[] errorSoon;                   // <--declared statement
String[] errorSoon = new String[100]; // <--initialized statement

You need to initialize the array so it can allocate the correct memory storage for the String elements before you can start setting the index.

If you only declare the array (as you did) there is no memory allocated for the String elements, but only a reference handle to errorSoon, and will throw an error when you try to initialize a variable at any index.

As a side note, you could also initialize the String array inside braces, { } as so,

String[] errorSoon = {"Hello", "World"};

which is equivalent to

String[] errorSoon = new String[2];
errorSoon[0] = "Hello";
errorSoon[1] = "World";

As of JDK6U18 following are configurations for the Heap Size.

In the Client JVM, the default Java heap configuration has been modified to improve the performance of today's rich client applications. Initial and maximum heap sizes are larger and settings related to generational garbage collection are better tuned.

The default maximum heap size is half of the physical memory up to a physical memory size of 192 megabytes and otherwise one fourth of the physical memory up to a physical memory size of 1 gigabyte. For example, if your machine has 128 megabytes of physical memory, then the maximum heap size is 64 megabytes, and greater than or equal to 1 gigabyte of physical memory results in a maximum heap size of 256 megabytes. The maximum heap size is not actually used by the JVM unless your program creates enough objects to require it. A much smaller amount, termed the initial heap size, is allocated during JVM initialization. This amount is at least 8 megabytes and otherwise 1/64 of physical memory up to a physical memory size of 1 gigabyte.

Or even easier and without the need to create a filter: use PHP's mb_strimwidth to truncate a string to a certain width (length). Just make sure you use one of the get_ syntaxes. For example with the content:

<?php $content = get_the_content(); echo mb_strimwidth($content, 0, 400, '...');?>

This will cut the string at 400 characters and close it with .... Just add a "read more"-link to the end by pointing to the permalink with get_permalink().

<a href="<?php the_permalink() ?>">Read more </a>

Of course you could also build the read more in the first line. Than just replace '...' with '<a href="' . get_permalink() . '">[Read more]</a>'

EDIT:

It seems that it's no longer necessary to have write access to a public repo to use an SSH URL, rendering my original explanation invalid.

ORIGINAL:

Apparently the main reason for favoring HTTPS URLs is that SSH URL's won't work with a public repo if you don't have write access to that repo.

The use of SSH URLs is encouraged for deployment to production servers, however - presumably the context here is services like Heroku.

re 1: This looks fine so far. Remember to return the URI of the newly created user in a "Location:" header as part of the response to POST, along with a "201 Created" status code.

re 2: Activation via GET is a bad idea, and including the verb in the URI is a design smell. You might want to consider returning a form on a GET. In a Web app, this would be an HTML form with a submit button; in the API use case, you might want to return a representation that contains a URI to PUT to to activate the account. Of course you can include this URI in the response on POST to /users, too. Using PUT will ensure your request is idempotent, i.e. it can safely be sent again if the client isn't sure about success. In general, think about what resources you can turn your verbs into (sort of "nounification of verbs"). Ask yourself what method your specific action is most closely aligned with. E.g. change_password -> PUT; deactivate -> probably DELETE; add_credit -> possibly POST or PUT. Point the client to the appropriate URIs by including them in your representations.

re 3. Don't invent new status codes, unless you believe they're so generic they merit being standardized globally. Try hard to use the most appropriate status code available (read about all of them in RFC 2616). Include additional information in the response body. If you really, really are sure you want to invent a new status code, think again; if you still believe so, make sure to at least pick the right category (1xx -> OK, 2xx -> informational, 3xx -> redirection; 4xx-> client error, 5xx -> server error). Did I mention that inventing new status codes is a bad idea?

re 4. If in any way possible, use the authentication framework built into HTTP. Check out the way Google does authentication in GData. In general, don't put API keys in your URIs. Try to avoid sessions to enhance scalability and support caching - if the response to a request differs because of something that has happened before, you've usually tied yourself to a specific server process instance. It's much better to turn session state into either client state (e.g. make it part of subsequent requests) or make it explicit by turning it into (server) resource state, i.e. give it its own URI.

Could you just draw an svg path inside of a span using document.write? The span isn't required for the svg to work, it just ensures that the svg remains inline with whatever text the carat is next to. I used margin-bottom to vertically center it with the text, there might be another way to do that though. This is what I did on my blog's side nav (minus the js). If you don't have text next to it you wouldn't need the span or the margin-bottom offset.

<div id="ID"></div>

<script type="text/javascript">
var x = document.getElementById('ID');

// your "margin-bottom" is the negative of 1/2 of the font size (in this example the font size is 16px)
// change the "stroke=" to whatever color your font is too
x.innerHTML = document.write = '<span><svg style="margin-bottom: -8px; height: 30px; width: 25px;" viewBox="0,0,100,50"><path fill="transparent" stroke-width="4" stroke="black" d="M20 10 L50 40 L80 10"/></svg></span>';
</script>

A one-liner solution. Result in bytes.

$size=array_sum(array_map('filesize', glob("{$dir}/*.*")));

Added bonus: you can simply change the file mask to whatever you like, and count only certain files (eg by extension).

Kubernetes and Mesos are a match made in heaven. Kubernetes enables the Pod (group of co-located containers) abstraction, along with Pod labels for service discovery, load-balancing, and replication control. Mesos provides the fine-grained resource allocations for pods across nodes in a cluster, and can make Kubernetes play nicely with other frameworks running on the same cluster resources.

Sometimes when I wan to explore around in a particular method and summoning pdb is just too cumbersome, I would add:

import IPython; IPython.embed()

IPython.embed() starts an IPython shell which have access to the local variables from the point where you call it.

If you are looking to create "printer friendly" pages, I recommend adding "!important" to your @media print CSS. This encourages most browsers to print your background images, colors, etc.

EXAMPLES:

background:#3F6CAF url('example.png') no-repeat top left !important;
background-color: #3F6CAF !important;

You can redirect stdout to nul to hide it.

COPY %scriptDirectory%test.bat %scriptDirectory%test2.bat >nul

Just add >nul to the commands you want to hide the output from.

Here you can see all the different ways of redirecting the std streams.

if you want to present new controller.

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let viewController = storyboard.instantiateViewController(withIdentifier: "controllerIdentifier") as! YourController
self.present(viewController, animated: true, completion: nil)

and if you want to push to another controller (if it is in navigation)

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let viewController = storyboard.instantiateViewController(withIdentifier: "controllerIdentifier") as! YourController
self.navigationController?.pushViewController(viewController, animated: true)

The 487 Response indicates that the previous request was terminated by user/application action. The most common occurrence is when the CANCEL happens as explained above. But it is also not limited to CANCEL. There are other cases where such responses can be relevant. So it depends on where you are seeing this behavior and whether its a user or application action that caused it.

15.1.2 UAS Behavior==> BYE Handling in RFC 3261

The UAS MUST still respond to any pending requests received for that dialog. It is RECOMMENDED that a 487 (Request Terminated) response be generated to those pending requests.

I know it's many years later, but I had been working on a similar issue recently and I wanted to post my solution. The currently accepted answer pads out the exponent part with 0's, and mine attempts to find the exact answer, although in general it isn't perfectly accurate for very large numbers because of JS's limit in floating point precision.

This does work for Math.pow(2, 100), returning the correct value of 1267650600228229401496703205376.

A somewhat clumsy ascii-art to demonstrate the mechanism: The join() is presumably called by the main-thread. It could also be called by another thread, but would needlessly complicate the diagram.

join-calling should be placed in the track of the main-thread, but to express thread-relation and keep it as simple as possible, I choose to place it in the child-thread instead.

without join:
+---+---+------------------                     main-thread
    |   |
    |   +...........                            child-thread(short)
    +..................................         child-thread(long)

with join
+---+---+------------------***********+###      main-thread
    |   |                             |
    |   +...........join()            |         child-thread(short)
    +......................join()......         child-thread(long)

with join and daemon thread
+-+--+---+------------------***********+###     parent-thread
  |  |   |                             |
  |  |   +...........join()            |        child-thread(short)
  |  +......................join()......        child-thread(long)
  +,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,     child-thread(long + daemonized)

'-' main-thread/parent-thread/main-program execution
'.' child-thread execution
'#' optional parent-thread execution after join()-blocked parent-thread could 
    continue
'*' main-thread 'sleeping' in join-method, waiting for child-thread to finish
',' daemonized thread - 'ignores' lifetime of other threads;
    terminates when main-programs exits; is normally meant for 
    join-independent tasks

So the reason you don't see any changes is because your main-thread does nothing after your join. You could say join is (only) relevant for the execution-flow of the main-thread.

If, for example, you want to concurrently download a bunch of pages to concatenate them into a single large page, you may start concurrent downloads using threads, but need to wait until the last page/thread is finished before you start assembling a single page out of many. That's when you use join().

First of all, from __future__ import print_function needs to be the first line of code in your script (aside from some exceptions mentioned below). Second of all, as other answers have said, you have to use print as a function now. That's the whole point of from __future__ import print_function; to bring the print function from Python 3 into Python 2.6+.

from __future__ import print_function

import sys, os, time

for x in range(0,10):
    print(x, sep=' ', end='')  # No need for sep here, but okay :)
    time.sleep(1)

__future__ statements need to be near the top of the file because they change fundamental things about the language, and so the compiler needs to know about them from the beginning. From the documentation:

A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime.

The documentation also mentions that the only things that can precede a __future__ statement are the module docstring, comments, blank lines, and other future statements.

The lazy-init="default" setting on a bean only refers to what is set by the default-lazy-init attribute of the enclosing beans element. The implicit default value of default-lazy-init is false.

If there is no lazy-init attribute specified on a bean, it's always eagerly instantiated.

The answer depends a little bit on the version of conda that you have installed. For versions of conda >= 4.4, it should be enough to deactivate the conda environment after the initialization, so add

conda deactivate

right underneath

# <<< conda initialize <<<

If you know what the sections are, you can do:

select top 10 * from table where section=1
union
select top 10 * from table where section=2
union
select top 10 * from table where section=3

I've used cx-freeze with good results in Python 3.2

Or you could git checkout -b <new-branch> and git cherry-pick <commit> the before to the and git rebase to drop revert commit. send pull request like before.

As @Antonijn stated, you need to execute getTitle method, by adding parentheses:

 string t = obj.getTitle();

But I want to add, that you are doing Java programming in C#. There is concept of properties (pair of get and set methods), which should be used in such cases:

public class Pin
{
    private string _title;

    // you don't need to define empty constructor
    // public Pin() { }

    public string Title 
    {
        get { return _title; }
        set { _title = value; }
    }  
}

And even more, in this case you can ask compiler not only for get and set methods generation, but also for back storage generation, via auto-impelemented property usage:

public class Pin
{
    public string Title { get; set; }
}

And now you don't need to execute method, because properties used like fields:

foreach (Pin obj in ClassListPin.pins)
{
     string t = obj.Title;
}

What I learnt from this question and the answers. Thanks all!

Let say I have these variables and functions:

$functionName1 = "sayHello";
$functionName2 = "sayHelloTo";
$functionName3 = "saySomethingTo";

$friend = "John";
$datas = array(
    "something"=>"how are you?",
    "to"=>"Sarah"
);

function sayHello()
{
echo "Hello!";
}

function sayHelloTo($to)
{
echo "Dear $to, hello!";
}

function saySomethingTo($something, $to)
{
echo "Dear $to, $something";
}

1. To call function without arguments

   // Calling sayHello()
   call_user_func($functionName1); 
   

   Hello!

2. To call function with 1 argument

   // Calling sayHelloTo("John")
   call_user_func($functionName2, $friend);
   

   Dear John, hello!

3. To call function with 1 or more arguments This will be useful if you are dynamically calling your functions and each function have different number of arguments. This is my case that I have been looking for (and solved). call_user_func_array is the key

   // You can add your arguments
   // 1. statically by hard-code, 
   $arguments[0] = "how are you?"; // my $something
   $arguments[1] = "Sarah"; // my $to
   
   // 2. OR dynamically using foreach
   $arguments = NULL;
   foreach($datas as $data) 
   {
       $arguments[] = $data;
   }
   
   // Calling saySomethingTo("how are you?", "Sarah")
   call_user_func_array($functionName3, $arguments);
   

   Dear Sarah, how are you?

Yay bye!

Top-Level await has moved to stage 3, so the answer to your question How can I use async/await at the top level? is to just add await the call to main() :

async function main() {
    var value = await Promise.resolve('Hey there');
    console.log('inside: ' + value);
    return value;
}

var text = await main();  
console.log('outside: ' + text)

Or just:

const text = await Promise.resolve('Hey there');
console.log('outside: ' + text)

No refresh is needed if the "val"-parameter is used for setting the value, see fiddle. Use brackets for the value to enable multiple selected values.

$('.selectpicker').selectpicker('val', [1]); 

There is yet another simpler way to get table names

SHOW TABLES FROM <database_name>

df = data.frame(matrix("", ncol = 3, nrow = 10)  

There is no relationship between error and firewall.

first, run server program,
then run client program in another shell of python

and it will work

I had the same problem and after spending 2 days researching I found this solution from Ksesocss that fits for me and maybe is good for you too. It allows fixed header and dynamic width and only uses CSS. The only problem is that the source is in spanish but you can find the html and css code there.

This is the link:

I hope this helps

For readability, I restructured the query... starting with the apparent top-most level being Table1, which then ties to Table3, and then table3 ties to table2. Much easier to follow if you follow the chain of relationships.

Now, to answer your question. You are getting a large count as the result of a Cartesian product. For each record in Table1 that matches in Table3 you will have X * Y. Then, for each match between table3 and Table2 will have the same impact... Y * Z... So your result for just one possible ID in table 1 can have X * Y * Z records.

This is based on not knowing how the normalization or content is for your tables... if the key is a PRIMARY key or not..

Ex:
Table 1       
DiffKey    Other Val
1          X
1          Y
1          Z

Table 3
DiffKey   Key    Key2  Tbl3 Other
1         2      6     V
1         2      6     X
1         2      6     Y
1         2      6     Z

Table 2
Key    Key2   Other Val
2      6      a
2      6      b
2      6      c
2      6      d
2      6      e

So, Table 1 joining to Table 3 will result (in this scenario) with 12 records (each in 1 joined with each in 3). Then, all that again times each matched record in table 2 (5 records)... total of 60 ( 3 tbl1 * 4 tbl3 * 5 tbl2 )count would be returned.

So, now, take that and expand based on your 1000's of records and you see how a messed-up structure could choke a cow (so-to-speak) and kill performance.

SELECT
      COUNT(*)
   FROM
      Table1 
         INNER JOIN Table3
            ON Table1.DifferentKey = Table3.DifferentKey
            INNER JOIN Table2
               ON Table3.Key =Table2.Key
               AND Table3.Key2 = Table2.Key2 

If you need to speed up the process (for example counting 30k or more files) then I would go with something like this..

$filepath = "c:\MyFolder"
$filetype = "*.txt"
$file_count = [System.IO.Directory]::GetFiles("$filepath", "$filetype").Count

It seems that Go have special form of switch dedicate to this (it is called type switch):

func (e *Easy)SetOption(option Option, param interface{}) {

    switch v := param.(type) { 
    default:
        fmt.Printf("unexpected type %T", v)
    case uint64:
        e.code = Code(C.curl_wrapper_easy_setopt_long(e.curl, C.CURLoption(option), C.long(v)))
    case string:
        e.code = Code(C.curl_wrapper_easy_setopt_str(e.curl, C.CURLoption(option), C.CString(v)))
    } 
}

This is probably more easily done with linq.js, which is intended to be a true implementation of LINQ in JavaScript (DEMO):

var linq = Enumerable.From(data);
var result =
    linq.GroupBy(function(x){ return x.Phase; })
        .Select(function(x){
          return {
            Phase: x.Key(),
            Value: x.Sum(function(y){ return y.Value|0; })
          };
        }).ToArray();

result:

[
    { Phase: "Phase 1", Value: 50 },
    { Phase: "Phase 2", Value: 130 }
]

Or, more simply using the string-based selectors (DEMO):

linq.GroupBy("$.Phase", "",
    "k,e => { Phase:k, Value:e.Sum('$.Value|0') }").ToArray();

Use insert method from range, for example

Sub InsertColumn()
        Columns("C:C").Insert Shift:=xlToRight, CopyOrigin:=xlFormatFromLeftOrAbove
        Range("C1").Value = "Loc"
End Sub

This doesn't seem to have <a> </a> tags so selenium might not be able to detect it as a link.

You may try and use

driver.findElement(By.xpath("//*[@class='ng-binding']")).click();

if this is the only element in that page with this class .

As Martin Thoma has said, you need to normally apply thresholding. But you can do this using simple vectorization which will run much faster than the for loop that is used in that answer.

The code below converts the pixels of an image into 0 (black) and 1 (white).

from PIL import Image
import numpy as np
import matplotlib.pyplot as plt

#Pixels higher than this will be 1. Otherwise 0.
THRESHOLD_VALUE = 200

#Load image and convert to greyscale
img = Image.open("photo.png")
img = img.convert("L")

imgData = np.asarray(img)
thresholdedData = (imgData > THRESHOLD_VALUE) * 1.0

plt.imshow(thresholdedData)
plt.show()

If the transfer mode is Buffered then make sure that the values of MaxReceivedMessageSize and MaxBufferSize is same. I just resolved the faulted state issue this way after grappling with it for hours and thought i'll post it here if it helps someone.

 SampleService srv1 = new SampleService();
     req = new Request();                     
     req.companyId = "1";
     req.userName = "userName";                                     
     req.password = "pas";
     Response response =    srv1.ServiceSample(req);

When you concatenate strings, you need to allocate memory to store the result. The easiest to start with is String and &str:

fn main() {
    let mut owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    owned_string.push_str(borrowed_string);
    println!("{}", owned_string);
}

Here, we have an owned string that we can mutate. This is efficient as it potentially allows us to reuse the memory allocation. There's a similar case for String and String, as &String can be dereferenced as &str.

fn main() {
    let mut owned_string: String = "hello ".to_owned();
    let another_owned_string: String = "world".to_owned();
    
    owned_string.push_str(&another_owned_string);
    println!("{}", owned_string);
}

After this, another_owned_string is untouched (note no mut qualifier). There's another variant that consumes the String but doesn't require it to be mutable. This is an implementation of the Add trait that takes a String as the left-hand side and a &str as the right-hand side:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    let new_owned_string = owned_string + borrowed_string;
    println!("{}", new_owned_string);
}

Note that owned_string is no longer accessible after the call to +.

What if we wanted to produce a new string, leaving both untouched? The simplest way is to use format!:

fn main() {
    let borrowed_string: &str = "hello ";
    let another_borrowed_string: &str = "world";
    
    let together = format!("{}{}", borrowed_string, another_borrowed_string);

    // After https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html
    // let together = format!("{borrowed_string}{another_borrowed_string}");

    println!("{}", together);
}

Note that both input variables are immutable, so we know that they aren't touched. If we wanted to do the same thing for any combination of String, we can use the fact that String also can be formatted:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let another_owned_string: String = "world".to_owned();
    
    let together = format!("{}{}", owned_string, another_owned_string);

    // After https://rust-lang.github.io/rfcs/2795-format-args-implicit-identifiers.html
    // let together = format!("{owned_string}{another_owned_string}");
    println!("{}", together);
}

You don't have to use format! though. You can clone one string and append the other string to the new string:

fn main() {
    let owned_string: String = "hello ".to_owned();
    let borrowed_string: &str = "world";
    
    let together = owned_string.clone() + borrowed_string;
    println!("{}", together);
}

Note - all of the type specification I did is redundant - the compiler can infer all the types in play here. I added them simply to be clear to people new to Rust, as I expect this question to be popular with that group!

ForcePush,

NOTE: The newly created mapped drive will now appear for ALL users of this system but they will see it displayed as "Disconnected Network Drive (Z:)". Do not let the name fool you. It may claim to be disconnected but it will work for everyone. That's how you can tell this hack is not supported by M$...

It all depends on the share permissions. If you have Everyone in the share permissions, this mapped drive will be accessible by other users. But if you have only some particular user whose credentials you used in your batch script and this batch script was added to the Startup scripts, only System account will have access to that share not even Administrator. So if you use, for example, a scheduled ntbackuo job, System account must be used in 'Run as'. If your service's 'Log on as: Local System account' it should work.

What I did, I didn't map any drive letter in my startup script, just used net use \\\server\share ... and used UNC path in my scheduled jobs. Added a logon script (or just add a batch file to the startup folder) with the mapping to the same share with some drive letter: net use Z: \\\... with the same credentials. Now the logged user can see and access that mapped drive. There are 2 connections to the same share. In this case the user doesn't see that annoying "Disconnected network drive ...". But if you really need access to that share by the drive letter not just UNC, map that share with the different drive letters, e.g. Y for System and Z for users.

But if I am the one who designs the API and gets to choose the data types, then what are the guidelines?

For input parameters it's best to accept the most generic interface that does what you need. It is seldom just a tuple or list - more often it's sequence, sliceable or even iterable. Python's duck typing usually gets it for free, unless you explicitly check input types. Don't do that unless absolutely unavoidable.

For the data that you produce (output parameters) just return what's most convenient for you, e.g. return whatever datatype you keep or whatever your helper function returns.

One thing to keep in mind is to avoid returning a list (or any other mutable) that's part of your state, e.g.

class ThingsKeeper
    def __init__(self):
        self.__things = []

    def things(self):
        return self.__things  #outside objects can now modify your state

    def safer(self):
        return self.__things[:]  #it's copy-on-write, shouldn't hurt performance

The below css works for both Chrome and Firefox

input[type=number]::-webkit-outer-spin-button,
input[type=number]::-webkit-inner-spin-button {
    -webkit-appearance: none;
    margin: 0;
}

input[type=number] {
    -moz-appearance:textfield;
}

A method for future reference is something like this. bannedphraseform is the first form and expectedphraseform is the second. If the first one is hit, the second one is skipped (which is a reasonable assumption in this case):

if request.method == 'POST':
    bannedphraseform = BannedPhraseForm(request.POST, prefix='banned')
    if bannedphraseform.is_valid():
        bannedphraseform.save()
else:
    bannedphraseform = BannedPhraseForm(prefix='banned')

if request.method == 'POST' and not bannedphraseform.is_valid():
    expectedphraseform = ExpectedPhraseForm(request.POST, prefix='expected')
    bannedphraseform = BannedPhraseForm(prefix='banned')
    if expectedphraseform.is_valid():
        expectedphraseform.save()

else:
    expectedphraseform = ExpectedPhraseForm(prefix='expected')

Google gives very low priority to text content contained inside a table. I was giving some SEO advice to a local charity. In examining their website it was using tables to layout the site. Looking at each page, no matter what words - or combination of words - from their pages I used in the Google search box the pages would not come up in any of the top search pages. (However, by specifying the site in the search the page was returned.) One page was well copy written by normal standards to produce a good result in a search but still it didn't appear in any of the first pages of search results returned. (Note this text was within a table.) I then spotted a section of text on the pages which was in a div rather than a table. We put a few of the words from that div in the search engine. Result? It came in at No.2 in the search result.
