var x = 10; 
  var y = 11; 
  var Queue = new Array();
  Queue.unshift(x);
  Queue.unshift(y);

  console.log(Queue)
  // Output [11, 10]

  Queue.pop()
  console.log(Queue)
  // Output [11]

\n

That means a new line is printed.

As a side note there is no need to write that extra line . There is an built in inbuilt function there.

 println()  //prints the content in new line

If you build the array in a loop, here is a simple way:

arr=()
for x in $(some_cmd); do
   arr+=($x,)
done
arr[-1]=${arr[-1]%,}
echo ${arr[*]}

This question is almost a year old but I have found that if you make a custom comparator for objects you can use Collections.max for an array list of objects.

import java.util.Comparator;

public class compPopulation implements Comparator<Country> {
    public int compare(Country a, Country b) {
        if (a.getPopulation() > b.getPopulation())
            return -1; // highest value first
        if (a.getPopulation() == b.Population())
            return 0;
        return 1;
    }
}
ArrayList<Country> X = new ArrayList<Country>();
// create some country objects and put in the list
Country ZZ = Collections.max(X, new compPopulation());

Use the Len function

length = Len(myString)

Try C# string interpolation introduced in C# 6:

var id = 100;
var hexid = $"0x{id:X}";

hexid value:

"0x64"

seeing as autocomplete=off is deprecated, I suggest a more recent solution.

Set your password field to a normal text field, and mask your input with "discs" using CSS. the code should look like this:

<input type="text" class="myPassword" /> 

input .myPassword{
    text-security:disc;
    -webkit-text-security:disc;
    -mox-text-security:disc;
}

Please note that this may not work propely on firefox browsers, and an additional walkaround is needed. Read more about it here :https://stackoverflow.com/a/49304708/5477548.

The solution was taken from this link, but to comply with SO "no-hotlinks" i summarized it here.

You are right, the function you're looking for is array_multisort().

Here's an example taken straight from the manual and adapted to your case:

$price = array();
foreach ($inventory as $key => $row)
{
    $price[$key] = $row['price'];
}
array_multisort($price, SORT_DESC, $inventory);

As of PHP 5.5.0 you can use array_column() instead of that foreach:

$price = array_column($inventory, 'price');

array_multisort($price, SORT_DESC, $inventory);

If I've understood your question correctly, then you are looking for the mouseup event, rather than the click event:

$("#message_link").mouseup(function() {
    //Do stuff here
});

The mouseup event fires when the mouse button is released, and does not take into account whether the mouse button was pressed on that element, whereas click takes into account both mousedown and mouseup.

However, click should work fine, because it won't actually fire until the mouse button is released.

try the + symbol: It is Adjacent sibling combinator. It combines two sequences of simple selectors having the same parent and the second one must come IMMEDIATELY after the first.

As such:

input[type="radio"]:checked+label{ font-weight: bold; } 
 //a label that immediately follows an input of type radio that is checked 

works very nicely for the following markup:

<input id="rad1" type="radio" name="rad"/><label for="rad1">Radio 1</label>
<input id="rad2" type="radio" name="rad"/><label for="rad2">Radio 2</label>

... and it will work for any structure, with or without divs etc as long as the label follows the radio input.

Example:

input[type="radio"]:checked+label { font-weight: bold; }

<input id="rad1" type="radio" name="rad"/><label for="rad1">Radio 1</label>_x000D_
<input id="rad2" type="radio" name="rad"/><label for="rad2">Radio 2</label>

SQLite supports a limited subset of ALTER TABLE. The ALTER TABLE command in SQLite allows the user to rename a table or to add a new column to an existing table. It is not possible to rename a column, remove a column, or add or remove constraints from a table. But you can alter table column datatype or other property by the following steps.

1. BEGIN TRANSACTION;
2. CREATE TEMPORARY TABLE t1_backup(a,b);
3. INSERT INTO t1_backup SELECT a,b FROM t1;
4. DROP TABLE t1;
5. CREATE TABLE t1(a,b);
6. INSERT INTO t1 SELECT a,b FROM t1_backup;
7. DROP TABLE t1_backup;
8. COMMIT

Just for completeness and historic interest, in the 64bit world there were different platform conventions on the sizes of long and long long types, named LLP64 and LP64, mainly between Unix-type systems and Windows. An old standard named ILP64 also made int = 64-bit wide.

Microsoft maintained LLP64 where longlong = 64 bit wide, but long remained at 32, for easier porting.

Type           ILP64   LP64   LLP64
char              8      8       8
short            16     16      16
int              64     32      32
long             64     64      32
long long        64     64      64
pointer          64     64      64

Old Answer it is kind of confusing. It gives you the LOCATIONS (all of them) of where your statment is true.

so:

>>> a = np.arange(100)
>>> np.where(a > 30)
(array([31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47,
       48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64,
       65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81,
       82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98,
       99]),)
>>> np.where(a == 90)
(array([90]),)

a = a*40
>>> np.where(a > 1000)
(array([26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42,
       43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59,
       60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76,
       77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93,
       94, 95, 96, 97, 98, 99]),)
>>> a[25]
1000
>>> a[26]
1040

I use it as an alternative to list.index(), but it has many other uses as well. I have never used it with 2D arrays.

New Answer It seems that the person was asking something more fundamental.

The question was how could YOU implement something that allows a function (such as where) to know what was requested.

First note that calling any of the comparison operators do an interesting thing.

a > 1000
array([False, False, False, False, False, False, False, False, False,
       False, False, False, False, False, False, False, False, False,
       False, False, False, False, False, False, False, False,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True,  True,  True,  True,  True,  True,  True,  True,  True,
        True`,  True,  True,  True,  True,  True,  True,  True,  True,  True], dtype=bool)`

This is done by overloading the "__gt__" method. For instance:

>>> class demo(object):
    def __gt__(self, item):
        print item


>>> a = demo()
>>> a > 4
4

As you can see, "a > 4" was valid code.

You can get a full list and documentation of all overloaded functions here: http://docs.python.org/reference/datamodel.html

Something that is incredible is how simple it is to do this. ALL operations in python are done in such a way. Saying a > b is equivalent to a.gt(b)!

Well, I don't have a function in python but I have a function in C which you can easily convert to python, in the below c function extended euclidian algorithm is used to calculate inverse mod.

int imod(int a,int n){
int c,i=1;
while(1){
    c = n * i + 1;
    if(c%a==0){
        c = c/a;
        break;
    }
    i++;
}
return c;}

Python Function

def imod(a,n):
  i=1
  while True:
    c = n * i + 1;
    if(c%a==0):
      c = c/a
      break;
    i = i+1

  return c

Reference to the above C function is taken from the following link C program to find Modular Multiplicative Inverse of two Relatively Prime Numbers

# This code works fine in QtSpim simulator

.data
    buffer: .space 20
    str1:  .asciiz "Enter string"

    la $a0, str1    # Load and print string asking for string
    li $v0, 4

    li $v0, 8       # take in input

    la $a0, buffer  # load byte space into address
    li $a1, 20      # allot the byte space for string

    move $t0, $a0   # save string to t0
    syscall

    la $a0, str2    # load and print "you wrote" string
    li $v0, 4

    la $a0, buffer  # reload byte space to primary address
    move $a0, $t0   # primary address = t0 address (load pointer)

As specified in oracle official tutorial , it states that:

If a client can reasonably be expected to recover from an exception, make it a checked exception. If a client cannot do anything to recover from the exception, make it an unchecked exception.

If I have an Application interacting with database using JDBC , And I have a method that takes the argument as the int item and double price. The price for corresponding item is read from database table. I simply multiply the total number of item purchased with the price value and return the result. Although I am always sure at my end(Application end) that price field value in the table could never be negative .But what if the price value comes out negative? It shows that there is a serious issue with the database side. Perhaps wrong price entry by the operator. This is the kind of issue that the other part of application calling that method can't anticipate and can't recover from it. It is a BUG in your database. So , and IllegalArguementException() should be thrown in this case which would state that the price can't be negative.
I hope that I have expressed my point clearly..

The accepted answer helped me but I got tripped up while doing concatenation of varchars involving case statements. I know the OP's question does not involve case statements but I thought this would be helpful to post here for others like me who ended up here while struggling to build long dynamic SQL statements involving case statements.

When using case statements with string concatenation the rules mentioned in the accepted answer apply to each section of the case statement independently.

declare @l_sql varchar(max) = ''

set @l_sql = @l_sql +
case when 1=1 then
    --without this correction the result is truncated
    --CONVERT(VARCHAR(MAX), '')
 +REPLICATE('1', 8000)
 +REPLICATE('1', 8000)
end

print len(@l_sql)

In MVC 4 you can link from one view to another controller passing the Id or Primary Key via

@Html.ActionLink("Select", "Create", "StudentApplication", new { id=item.PersonId }, null) 

For completeness - adding to accepted answer above - in case you are interested in any sibling regardless of the element type you can use variation:

following-sibling::*

It should be considered an error. But C is an ancient language, so it's only a warning.
Compiling with -Werror (gcc) fixes this problem.

When C doesn't find a declaration, it assumes this implicit declaration: int f();, which means the function can receive whatever you give it, and returns an integer. If this happens to be close enough (and in case of printf, it is), then things can work. In some cases (e.g. the function actually returns a pointer, and pointers are larger than ints), it may cause real trouble.

Note that this was fixed in newer C standards (C99, C11). In these standards, this is an error. However, gcc doesn't implement these standards by default, so you still get the warning.

Please use the below command to get the IP address of the running container.

The below code working for me on array coming from ajax call .

  $form = $request->input('form');
  $rules = array(
            'facebook_account' => 'url',
            'youtube_account' => 'url',
            'twitter_account' => 'url',
            'instagram_account' => 'url',
            'snapchat_account' => 'url',
            'website' => 'url',
        );
        $validation = Validator::make($form, $rules);

        if ($validation->fails()) {
            return Response::make(['error' => $validation->errors()], 400);
        }

In SQL*Plus putting SET DEFINE ? at the top of the script will normally solve this. Might work for Oracle SQL Developer as well.

Doubles are just like floats, except for the fact that they are twice as large. This allows for a greater accuracy.

Here is one way (put this in Page_Load):

if (this.IsPostBack)
{
    Page.ClientScript.RegisterStartupScript(this.GetType(),"PostbackKey","<script type='text/javascript'>var isPostBack = true;</script>");
}

Then just check that variable in the JS.

In another way to limit a string in php and add on readmore text or like '...' using below code

if (strlen(preg_replace('#^https?://#', '', $string)) > 30) { 
    echo substr(preg_replace('#^https?://#', '', $string), 0, 35).'…'; 
}

You can give like this

public static function getAll()
{

    return $posts = $this->all()->take(2)->get();

}

And when you call statically inside your controller function also..

If antak's answer:

If you want user to change between WindowStyle.SingleBorderWindow and WindowStyle.None at runtime you can bring this at code behind:

Make application fullscreen:

RootWindow.Visibility = Visibility.Collapsed;
RootWindow.WindowStyle = WindowStyle.None;
RootWindow.ResizeMode = ResizeMode.NoResize;
RootWindow.WindowState = WindowState.Maximized;
RootWindow.Topmost = true;
RootWindow.Visibility = Visibility.Visible;

Return to single border style:

RootWindow.WindowStyle = WindowStyle.SingleBorderWindow;
RootWindow.ResizeMode = ResizeMode.CanResize;
RootWindow.Topmost = false;

Note that without RootWindow.Visibility property your window will not cover start menu, however you can skip this step if you making application fullscreen once at startup.

The rule is as following :

A B 

B as a descendant of A

A > B 

B as a child of A

So

div.dropdown *

and not

div.dropdown > *

Note that exit codes != 0 are used to report error. So, it's better to do:

retVal=$?
if [ $retVal -ne 0 ]; then
    echo "Error"
fi
exit $retVal

instead of

# will fail for error codes > 1
retVal=$?
if [ $retVal -eq 1 ]; then
    echo "Error"
fi
exit $retVal

Taking help from above answer link mentioned in the above answer sets the max value with option

yAxis: { max: 100 },

On similar line min value can be set.So if you want to set min-max value then

yAxis: {
   min: 0,     
   max: 100
},

If you are using HighRoller php library for integration if Highchart graphs then you just need to set the option

$series->yAxis->min=0;
$series->yAxis->max=100;

Use this tool (hosted here for free) to convert your curl command to equivalent Python requests code:

Example: This,

curl 'https://www.example.com/' -H 'Connection: keep-alive' -H 'Cache-Control: max-age=0' -H 'Origin: https://www.example.com' -H 'Accept-Encoding: gzip, deflate, br' -H 'Cookie: SESSID=ABCDEF' --data-binary 'Pathfinder' --compressed

Gets converted neatly to:

import requests

cookies = {
    'SESSID': 'ABCDEF',
}

headers = {
    'Connection': 'keep-alive',
    'Cache-Control': 'max-age=0',
    'Origin': 'https://www.example.com',
    'Accept-Encoding': 'gzip, deflate, br',
}

data = 'Pathfinder'

response = requests.post('https://www.example.com/', headers=headers, cookies=cookies, data=data)

Here is a (hopefully) universal patch I developed to fix this problem for BootStrap V3. No special requirements other than plugging in the script.

$(':not(.panel) > [data-toggle="collapse"][data-parent]').click(function() {
    var parent = $(this).data('parent');
    var items = $('[data-toggle="collapse"][data-parent="' + parent + '"]').not(this);
    items.each(function() {
        var target = $(this).data('target') || '#' + $(this).prop('href').split('#')[1];
        $(target).filter('.in').collapse('hide');
    });
});

EDIT: Below is a simplified answer which still meets my needs, and I'm now using a delegated click handler:

$(document.body).on('click', ':not(.panel) > [data-toggle="collapse"][data-parent]', function() {
    var parent = $(this).data('parent');
    var target = $(this).data('target') || $(this).prop('hash');
    $(parent).find('.collapse.in').not(target).collapse('hide');
});

A bit of encoding can solve this:

Client Side:

message = input("->")
clientSocket.sendto(message.encode('utf-8'), (address, port))

Server Side:

data = s.recv(1024)
modifiedMessage, serverAddress = clientSocket.recvfrom(message.decode('utf-8'))

This seems to be an issue with an old version of OpenSSL being incompatible with pip 1.3.1. If you're using a non-stock Python distribution (notably EPD 7.3), you're very likely to have a setup that isn't going to work with pip 1.3.1 without a shitload of work.

The easy workaround for now, is to install pip 1.2.1, which does not require SSL:

curl -O https://pypi.python.org/packages/source/p/pip/pip-1.2.1.tar.gz
tar xvfz pip-1.2.1.tar.gz
cd pip-1.2.1
python setup.py install

If you are using EPD, and you're not using it for a class where things might break, you may want to consider installing the new incarnation: Enthought Canopy. I know they were aware of the issues caused by the previous version of OpenSSL, and would imagine they are using a new version now that should play nicely with pip 1.3.1.

• If you are in base directory location of your tracked files then git checkout . will works otherwise it won't work

just remenber that 'on' is recomended over the 'bind' function, so always try to use a event listener like this:

$("#myTextBox").on("change paste keyup", function() {
   alert($(this).val()); 
});

How about..

var result = (from s in context.Shift join es in employeeshift on s.shiftid equals es.shiftid where es.empid == 57 select s)

Edit: This will give you shifts where there is an associated employeeshift (because of the join). For the "not exists" I'd do what @ArsenMkrt or @hyp suggest

you can achive this by calling a function also

<div [style.width.px]="getCustomeWidth()"></div>

  getCustomeWidth() {
    //do what ever you want here
    return customeWidth;
  }

Here is something that's pretty interesting. Although exit() and die() are equivalent, die() closes the connection. exit() doesn't close the connection.

die():

<?php
    header('HTTP/1.1 304 Not Modified');
    die();
?>

exit():

<?php
    header('HTTP/1.1 304 Not Modified');
    exit();
?>

Results:

exit():

Connection: Keep-Alive 
Keep-Alive: timeout=5, max=100

die():

The string representation of a float doesn't work this way. For example, repr(1.3) yields '1.3', but repr(1.33) yields '1.3300000000000001'.

A accurate string representation of a floating point number produces a variable length string.

Because numpy arrays consist of elements that are all the same size, numpy requires you to specify the length of the strings within the array when you're using string arrays.

If you use x.astype('str'), it will always convert things to an array of strings of length 1.

For example, using x = np.array(1.344566), x.astype('str') yields '1'!

You need to be more explict and use the '|Sx' dtype syntax, where x is the length of the string for each element of the array.

For example, use x.astype('|S10') to convert the array to strings of length 10.

Even better, just avoid using numpy arrays of strings altogether. It's usually a bad idea, and there's no reason I can see from your description of your problem to use them in the first place...

Here is a universal approach for registering cells in UITableView:

protocol Reusable {
    static var reuseID: String { get }
}

extension Reusable {
    static var reuseID: String {
        return String(describing: self)
    }
}

extension UITableViewCell: Reusable { }

extension UITableView {

func register<T: UITableViewCell>(cellClass: T.Type = T.self) {
    let bundle = Bundle(for: cellClass.self)
    if bundle.path(forResource: cellClass.reuseID, ofType: "nib") != nil {
        let nib = UINib(nibName: cellClass.reuseID, bundle: bundle)
        register(nib, forCellReuseIdentifier: cellClass.reuseID)
    } else {
        register(cellClass.self, forCellReuseIdentifier: cellClass.reuseID)
    }
}

Explanation:

1. Reusable protocol generates cell ID from its class name. Make sure you follow the convention: cell ID == class name == nib name.
2. UITableViewCell conforms to Reusable protocol.
3. UITableView extension abstracts away the difference in registering cells via nib or class.

Usage example:

override func viewDidLoad() {
    super.viewDidLoad()
    let tableView = UITableView()
    let cellClasses: [UITableViewCell.Type] = [PostCell.self, ProfileCell.self, CommentCell.self]
    cellClasses.forEach(tableView.register)
}

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: PostCell.self.reuseID) as? PostCell
    ...
    return cell
}

You can also write code as

for(int i=0;i<n;i++)
{
      //statements;
      i=i+2;//cause you want to increment i by 3 
}

i have used this and solved my

Changing the IDENTITY property is really a metadata only change. But to update the metadata directly requires starting the instance in single user mode and messing around with some columns in sys.syscolpars and is undocumented/unsupported and not something I would recommend or will give any additional details about.

For people coming across this answer on SQL Server 2012+ by far the easiest way of achieving this result of an auto incrementing column would be to create a SEQUENCE object and set the next value for seq as the column default.

Alternatively, or for previous versions (from 2005 onwards), the workaround posted on this connect item shows a completely supported way of doing this without any need for size of data operations using ALTER TABLE...SWITCH. Also blogged about on MSDN here. Though the code to achieve this is not very simple and there are restrictions - such as the table being changed can't be the target of a foreign key constraint.

Example code.

Set up test table with no identity column.

CREATE TABLE dbo.tblFoo 
(
bar INT PRIMARY KEY,
filler CHAR(8000),
filler2 CHAR(49)
)


INSERT INTO dbo.tblFoo (bar)
SELECT TOP (10000) ROW_NUMBER() OVER (ORDER BY (SELECT 0))
FROM master..spt_values v1, master..spt_values v2

Alter it to have an identity column (more or less instant).

BEGIN TRY;
    BEGIN TRANSACTION;

    /*Using DBCC CHECKIDENT('dbo.tblFoo') is slow so use dynamic SQL to
      set the correct seed in the table definition instead*/
    DECLARE @TableScript nvarchar(max)
    SELECT @TableScript = 
    '
    CREATE TABLE dbo.Destination(
        bar INT IDENTITY(' + 
                     CAST(ISNULL(MAX(bar),0)+1 AS VARCHAR) + ',1)  PRIMARY KEY,
        filler CHAR(8000),
        filler2 CHAR(49)
        )

        ALTER TABLE dbo.tblFoo SWITCH TO dbo.Destination;
    '       
    FROM dbo.tblFoo
    WITH (TABLOCKX,HOLDLOCK)

    EXEC(@TableScript)


    DROP TABLE dbo.tblFoo;

    EXECUTE sp_rename N'dbo.Destination', N'tblFoo', 'OBJECT';


    COMMIT TRANSACTION;
END TRY
BEGIN CATCH
    IF XACT_STATE() <> 0 ROLLBACK TRANSACTION;
    PRINT ERROR_MESSAGE();
END CATCH;

Test the result.

INSERT INTO dbo.tblFoo (filler,filler2) 
OUTPUT inserted.*
VALUES ('foo','bar')

Gives

bar         filler    filler2
----------- --------- ---------
10001       foo       bar      

Clean up

DROP TABLE dbo.tblFoo

just simple:

.navbar{
    width:65% !important;
    margin:0px auto;
    left:0;
    right:0;
    padding:0;
}

or,

.navbar.navbar-fixed-top{
    width:65% !important;
    margin:0px auto;
    left:0;
    right:0;
    padding:0;
}

Hope it works (at least, for future searchers)

Here's something I found:

:pingtheserver
ping %input% | find "Reply" > nul
if not errorlevel 1 (
    echo server is online, up and running.
) else (
    echo host has been taken down wait 3 seconds to refresh
    ping 1.1.1.1 -n 1 -w 3000 >NUL
    goto :pingtheserver
) 

Note that ping 1.1.1.1 -n -w 1000 >NUL will wait 1 second but only works when connected to a network

Airdroid , android market install the app on android then go onto the computer type in the address given, type in the password given (or scan the QR code). Go to settings and under security (if your running the new ICS or Jellybean) or go to settings->apps->managment and select unknown sources(for gingerbread) then click on (I think) speed install, or something along those lines. it will be on the top of the page slightly towards the left. drag and drop as many .apks as you want then on you android just tap the install buttons that appear. Airdroid is wonderful and does a lot more than just apks.

matplotlib 1.5+

You can use axes.set_prop_cycle (example).

matplotlib 1.0-1.4

You can use axes.set_color_cycle (example).

matplotlib 0.x

You can use Axes.set_default_color_cycle.

Permissions that Imply Feature Requirements

example, the android.hardware.bluetooth feature was added in Android 2.2 (API level 8), but the bluetooth API that it refers to was added in Android 2.0 (API level 5). Because of this, some apps were able to use the API before they had the ability to declare that they require the API via the system.

To prevent those apps from being made available unintentionally, Google Play assumes that certain hardware-related permissions indicate that the underlying hardware features are required by default. For instance, applications that use Bluetooth must request the BLUETOOTH permission in a element — for legacy apps, Google Play assumes that the permission declaration means that the underlying android.hardware.bluetooth feature is required by the application and sets up filtering based on that feature.

The table below lists permissions that imply feature requirements equivalent to those declared in elements. Note that declarations, including any declared android:required attribute, always take precedence over features implied by the permissions below.

For any of the permissions below, you can disable filtering based on the implied feature by explicitly declaring the implied feature explicitly, in a element, with an android:required="false" attribute. For example, to disable any filtering based on the CAMERA permission, you would add this declaration to the manifest file:

<uses-feature android:name="android.hardware.camera" android:required="false" />


<uses-feature android:name="android.hardware.bluetooth" android:required="false" />
<uses-feature android:name="android.hardware.location" android:required="false" />
<uses-feature android:name="android.hardware.location.gps" android:required="false" />
<uses-feature android:name="android.hardware.telephony" android:required="false" />
<uses-feature android:name="android.hardware.wifi" android:required="false" />

http://developer.android.com/guide/topics/manifest/uses-feature-element.html#permissions

You shouldn't be importing android.R. That should be automatically generated and recognized. This question contains a lot of helpful tips if you get some error referring to R after removing the import.

Some basic steps after removing the import, if those errors appear:

• Clean your build, then rebuild
• Make sure there are no errors or typos in your XML files
• Make sure your resource names consist of [a-z0-9.]. Capitals or symbols are not allowed for some reason.
• Perform a Gradle sync (via Tools > Android > Sync Project with Gradle Files)

Faster than the above solutions, including the highest rated one:

(x < 0) ? -1 : (x > 0)

Try indextank.

As the case of elastic search, it was conceived to be much easier to use than lucene/solr. It also includes very flexible scoring system that can be tweaked without reindexing.

I had the same error because I was using proxy. As the answer is given but in case you are using proxy then please set your proxy first using these commands:

git config --global http.proxy http://proxy_username:proxy_password@proxy_ip:port
git config --global https.proxy https://proxy_username:proxy_password@proxy_ip:port

import requests

url = requests.get("http://yahoo.com")
htmltext = url.text
print(htmltext)

This will work similar to urllib.urlopen.

I have been battling this for a about a week. I'm trying to learn Java on Netbeans IDE and so naturally I get the combo file straight from Oracle. Which is a package of the JDK and the Netbeans IDE together in a tar file located here.

located http://www.oracle.com/technetwork/java/javase/downloads/index.html file name JDK 8u25 with NetBeans 8.0.1

after installing them (or so I thought) I would make/compile a simple program like "hello world" and that would spit out a jar file that you would be able to run in a terminal. Keep in mind that the program ran in the Netbeans IDE.

I would end up with this error: java.lang.UnsupportedClassVersionError:

Even though I ran the file from oracle website I still had the old version of the Java runtime which was not compatible to run my jar file which was compiled with the new java runtime.

After messing with stuff that was mostly over my head from setting Paths to editing .bashrc with no remedy.

I came across a solution that was easy enough for even me. I have come across something that auto installs java and configures it on your system and it works with the latest 1.8.*

One of the steps is adding a PPA wasn't sure about this at first but seems ok as it has worked for me

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java8-installer

domenic@domenic-AO532h ~ $ java -version java version "1.8.0_25" Java(TM) SE Runtime Environment (build 1.8.0_25-b17) Java HotSpot(TM) Server VM (build 25.25-b02, mixed mode)

I think it also configures the browser java as well.

I hope this helps others.

Try this:

import matplotlib as plt

after importing the file we can use matplotlib library but remember to use it as plt

df.plt(kind='line',figsize=(10,5))

after that the plot will be done and size increased. In figsize the 10 is for breadth and 5 is for height. Also other attributes can be added to the plot too.

As an alternative representation you could use

[in] '%s' % hex(15)
[out]'0xf'

This can be done with 3 lines of CSS and is compatible back to (and including) IE9:

.element {
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

If your class performs all of its initialization in the constructor, then @PostConstruct is indeed redundant.

However, if your class has its dependencies injected using setter methods, then the class's constructor cannot fully initialize the object, and sometimes some initialization needs to be performed after all the setter methods have been called, hence the use case of @PostConstruct.

I doubt you'll get a better answer than, "Guido didn't feel the need for multi-line comments".

Guido has tweeted about this:

Python tip: You can use multi-line strings as multi-line comments. Unless used as docstrings, they generate no code! :-)

you have to use the 'prop' function :

.prop('checked', true);

Before jQuery 1.6 (see user2063626's answer):

.attr('checked','checked')

Perhaps you are looking for a context manager?

>>> class Foo(object):
...   def __init__(self):
...     self.bar = None
...   def __enter__(self):
...     if self.bar != 'open':
...       print 'opening the bar'
...       self.bar = 'open'
...   def __exit__(self, type_, value, traceback):
...     if self.bar != 'closed':
...       print 'closing the bar', type_, value, traceback
...       self.bar = 'close'
... 
>>> 
>>> with Foo() as f:
...     # oh no something crashes the program
...     sys.exit(0)
... 
opening the bar
closing the bar <type 'exceptions.SystemExit'> 0 <traceback object at 0xb7720cfc>

Simply use :

"SELECT * FROM `trees` WHERE LOWER(trees.`title`) LIKE  '%elm%'";

Or Use

"SELECT * FROM `trees` WHERE LCASE(trees.`title`) LIKE  '%elm%'";

Both functions works same

Note that typeof always returns a string, and doesn't generate an error if the variable doesn't exist at all.

function A(val){
  if(typeof(val)  === "undefined") 
    //do this
  else
   //do this
}

An easy solution working on Linux distributions similar to Ubuntu

sudo php5dismod xdebug
sudo service apache2 restart

If you're using PHP 5.3+ take a look at the $before_needle flag of strstr()

$s = 'Posted On April 6th By Some Dude';
echo strstr($s, 'By', true);

I imagine this forum posting, which I quote fully below, should answer the question.

Inside a procedure, function, or trigger definition, or in a dynamic SQL statement (embedded in a host program):

BEGIN ATOMIC
 DECLARE example VARCHAR(15) ;
 SET example = 'welcome' ;
 SELECT *
 FROM   tablename
 WHERE  column1 = example ;
END

or (in any environment):

WITH t(example) AS (VALUES('welcome'))
SELECT *
FROM   tablename, t
WHERE  column1 = example

or (although this is probably not what you want, since the variable needs to be created just once, but can be used thereafter by everybody although its content will be private on a per-user basis):

CREATE VARIABLE example VARCHAR(15) ;
SET example = 'welcome' ;
SELECT *
FROM   tablename
WHERE  column1 = example ;

I wrote git-playback for this exact purpose

pip install git-playback
git playback [filename]

This has the benefit of both displaying the results in the command line (like git log -p) while also letting you step through each commit using the arrow keys (like gitk).

The .cpp file is configured to use precompiled header, therefore it must be included first (before iostream). For Visual Studio, it's name is usually "stdafx.h".

If there are no stdafx* files in your project, you need to go to this file's options and set it as “Not using precompiled headers”.

if you put all the searched words in a temporaray table say @tmp and column col1, then you could try this:

Select * from T where C like (Select '%'+col1+'%' from @temp);

If you want to count LOC you have written, you may need to exclude some files.

For a Django project, you may want to ignore the migrations and static folders. For a JavaScript project, you may exclude all pictures or all fonts.

find . \( -path '*/migrations' -o -path '*/.git' -o -path '*/.vscode' -o -path '*/fonts' -o -path '*.png' -o -path '*.jpg' -o -path '*/.github' -o -path '*/static' \) -prune -o -type f -exec cat {} + | wc -l

Usage here is as follows:

*/folder_name
*/.file_extension

To list the files, modify the latter part of the command:

find . \( -path '*/migrations' -o -path '*/.git' -o -path '*/.vscode' -o -path '*/fonts' -o -path '*.png' -o -path '*.jpg' -o -path '*/.github' -o -path '*/static' \) -prune -o --print

SourceForge uses an <iframe> element with the src="" attribute pointing to the file to download.

<iframe width="1" height="1" frameborder="0" src="[File location]"></iframe>

(Side effect: no redirect, no JavaScript, original URL remains unchanged.)

May be it's due to the deprecation of sklearn.cross_validation. Please replace sklearn.cross_validation with sklearn.model_selection

If both "document.ready" variants are used they will both fire, in the order of appearance

$(function(){
    alert('shorthand document.ready');
});

//try changing places
$(document).ready(function(){
    alert('document.ready');
});

From your example, it seems to me you want to use a static method.

class mystuff:
  @staticmethod
  def average(a,b,c): #get the average of three numbers
    result=a+b+c
    result=result/3
    return result

print mystuff.average(9,18,27)

Please note that an heavy usage of static methods in python is usually a symptom of some bad smell - if you really need functions, then declare them directly on module level.

multipart/form-data

is used when you want to upload files to the server. Please check this article for details.

This is an improvement over @Mottie's answer because as of jQuery 1.5.2 :text selects input elements that have no specified type attribute (in which case type="text" is implied):

$('form').find(':text,textarea,select').filter(':visible:first')

(foobar == foo || foobar == bar) otherwise if you are comparing expressions based only on a single integer, enumerated value, or String object you can use switch. See The switch Statement. You can also use the method suggested by André Alçada Padez. Ultimately what you select will need to depend on the details of what you are doing.

Based on the above suggestions, the following data.table solution worked very fast for me:

library(data.table)

set.seed(45)
DT <- data.table(matrix(sample(10, 10^7, TRUE), ncol=10))

system.time(
  DT[, col_max := colnames(.SD)[max.col(.SD, ties.method = "first")]]
)
#>    user  system elapsed 
#>    0.15    0.06    0.21
DT[]
#>          V1 V2 V3 V4 V5 V6 V7 V8 V9 V10 col_max
#>       1:  7  4  1  2  3  7  6  6  6   1      V1
#>       2:  4  6  9 10  6  2  7  7  1   3      V4
#>       3:  3  4  9  8  9  9  8  8  6   7      V3
#>       4:  4  8  8  9  7  5  9  2  7   1      V4
#>       5:  4  3  9 10  2  7  9  6  6   9      V4
#>      ---                                       
#>  999996:  4  6 10  5  4  7  3  8  2   8      V3
#>  999997:  8  7  6  6  3 10  2  3 10   1      V6
#>  999998:  2  3  2  7  4  7  5  2  7   3      V4
#>  999999:  8 10  3  2  3  4  5  1  1   4      V2
#> 1000000: 10  4  2  6  6  2  8  4  7   4      V1

And also comes with the advantage that can always specify what columns .SD should consider by mentioning them in .SDcols:

DT[, MAX2 := colnames(.SD)[max.col(.SD, ties.method="first")], .SDcols = c("V9", "V10")]

In case we need the column name of the smallest value, as suggested by @lwshang, one just needs to use -.SD:

DT[, col_min := colnames(.SD)[max.col(-.SD, ties.method = "first")]]

There are extensions of Word2Vec intended to solve the problem of comparing longer pieces of text like phrases or sentences. One of them is paragraph2vec or doc2vec.

"Distributed Representations of Sentences and Documents" http://cs.stanford.edu/~quocle/paragraph_vector.pdf

http://rare-technologies.com/doc2vec-tutorial/

You should have a look at moment which is a python port of the excellent js lib momentjs.

One advantage of it is the support of ISO 8601 strings formats, as well as a generic "% format" :

import moment
time_string='2012-10-09T19:00:55Z'

m = moment.date(time_string, '%Y-%m-%dT%H:%M:%SZ')
print m.format('YYYY-M-D H:M')
print m.weekday

Result:

2012-10-09 19:10

function splitText(value, index) {
  if (value.length < index) {return value;} 
  return [value.substring(0, index)].concat(splitText(value.substring(index), index));
}
console.log(splitText('this is a testing peace of text',10));
// ["this is a ", "testing pe", "ace of tex", "t"] 

For those who want to split a text into array using the index.

I had a similar problem understanding why JpaRespository.getOne(id) does not work and throw an error.

I went and change to JpaRespository.findById(id) which requires you to return an Optional.

This is probably my first comment on StackOverflow.

I recently found a node command that allows uninstalling all the development dependencies as follows:

npm prune --production

As I mentioned, this command only uninstalls the development dependency packages. At least it helped me not to have to do it manually.

If installing on Ubuntu using apt-get, try /usr/share/nginx/www.

EDIT:

On more recent versions the path has changed to: /usr/share/nginx/html

2019 EDIT:

Might try in /var/www/html/index.nginx-debian.html too.

If you need to have jquery use !important for more than one item, this is how you would do it.

e.g. set an img tags max-width and max-height to 500px each

$('img').css('cssText', "max-width: 500px !important;' + "max-height: 500px !important;');

word-wrap: break-word; 

add this to your container that should do the trick

@Override
protected Dialog onCreateDialog(int id)
{
    switch(id)
    {
    case 0:
    {               
        return new AlertDialog.Builder(this)
        .setMessage("text here")
        .setPositiveButton("OK", new DialogInterface.OnClickListener() 
        {                   
            @Override
            public void onClick(DialogInterface arg0, int arg1) 
            {
                try
                {

                }//end try
                catch(Exception e)
                {
                    Toast.makeText(getBaseContext(),  "", Toast.LENGTH_LONG).show();
                }//end catch
            }//end onClick()
        }).create();                
    }//end case
  }//end switch
    return null;
}//end onCreateDialog

There is at least one middleware on npm for handling CORS in Express: cors. [see @mscdex answer]

This is how to set custom response headers, from the ExpressJS DOC

res.set(field, [value])

Set header field to value

res.set('Content-Type', 'text/plain');

or pass an object to set multiple fields at once.

res.set({
  'Content-Type': 'text/plain',
  'Content-Length': '123',
  'ETag': '12345'
})

Aliased as

res.header(field, [value])

When you create a StreamWriter it always create a file from scratch, you will have to create a third file and copy from target and replace what you need, and then replace the old one. But as I can see what you need is XML manipulation, you might want to use XmlDocument and modify your file using Xpath.

SQL Server Express doesn't include SQL Server Agent, so it's not possible to just create SQL Agent jobs.

What you can do is:
You can create jobs "manually" by creating batch files and SQL script files, and running them via Windows Task Scheduler.
For example, you can backup your database with two files like this:

backup.bat:

sqlcmd -i backup.sql

backup.sql:

backup database TeamCity to disk = 'c:\backups\MyBackup.bak'

Just put both files into the same folder and exeute the batch file via Windows Task Scheduler.

The first file is just a Windows batch file which calls the sqlcmd utility and passes a SQL script file.
The SQL script file contains T-SQL. In my example, it's just one line to backup a database, but you can put any T-SQL inside. For example, you could do some UPDATE queries instead.

If the jobs you want to create are for backups, index maintenance or integrity checks, you could also use the excellent Maintenance Solution by Ola Hallengren.

It consists of a bunch of stored procedures (and SQL Agent jobs for non-Express editions of SQL Server), and in the FAQ there’s a section about how to run the jobs on SQL Server Express:

How do I get started with the SQL Server Maintenance Solution on SQL Server Express?

SQL Server Express has no SQL Server Agent. Therefore, the execution of the stored procedures must be scheduled by using cmd files and Windows Scheduled Tasks. Follow these steps.

SQL Server Express has no SQL Server Agent. Therefore, the execution of the stored procedures must be scheduled by using cmd files and Windows Scheduled Tasks. Follow these steps.

1. Download MaintenanceSolution.sql.

2. Execute MaintenanceSolution.sql. This script creates the stored procedures that you need.

3. Create cmd files to execute the stored procedures; for example:
   sqlcmd -E -S .\SQLEXPRESS -d master -Q "EXECUTE dbo.DatabaseBackup @Databases = 'USER_DATABASES', @Directory = N'C:\Backup', @BackupType = 'FULL'" -b -o C:\Log\DatabaseBackup.txt

4. In Windows Scheduled Tasks, create tasks to call the cmd files.

5. Schedule the tasks.

6. Start the tasks and verify that they are completing successfully.

I couldn't find a direct GDrive/DropBox solution. I'm also surprised there's no lazy solution for a free ftp host. Windows azure offers a ftp server "FTP connector" that's fairly easy to turn on at: https://portal.azure.com

You can get a free 1 GB account by selecting "View All" machine types during your deployment.

int i;
int j;

int * const ptr1 = &i;

The compiler will stop you changing ptr1.

const int * ptr2 = &i;

The compiler will stop you changing *ptr2.

ptr1 = &j; // error
*ptr1 = 7; // ok

ptr2 = &j; // ok
*ptr2 = 7; // error

Note that you can still change *ptr2, just not by literally typing *ptr2:

i = 4;
printf("before: %d\n", *ptr2); // prints 4
i = 5;
printf("after: %d\n", *ptr2); // prints 5
*ptr2 = 6; // still an error

You can also have a pointer with both features:

const int * const ptr3 = &i;

ptr3 = &j; // error
*ptr3 = 7; // error

In Eclipse, go to windows -> preferences -> gradle->arguments. Find JVM Arguments choose from radio button "USE :" and write arguments -Xms128m -Xmx512m Then click button Apply

Here's yet another way (using a negative look-ahead):

^/(?!ignoreme|ignoreme2|ignoremeN)([a-z0-9]+)$ 

Note: There's only one capturing expression: ([a-z0-9]+).

My UTF-8 compliant version:

preg_replace('/[^\p{L}\s]/u','',$value);

You can try this:

import os

current_dir = os.path.dirname(os.path.abspath(__file__))   # Can also use os.getcwd()
print(current_dir)                                         # prints(say)- D:\abc\def\ghi\jkl\mno"
new_dir = os.chdir('..\\..\\..\\')                         
print(new_dir)                                             # prints "D:\abc\def\ghi"

curl -X PUT -d 'new_value' URL_PATH/key

where,

X - option to be used for request command

d - option to be used in order to put data on remote url

URL_PATH - remote url

new_value - value which we want to put to the server's key

Wikipedia, of all places, actually discusses this.

The idea is to make sure all package names are unique world-wide, by having authors use a variant of a DNS name they own to name the package. For example, the owners of the domain name joda.org created a number of packages whose names begin with org.joda, for example:

• org.joda.time
• org.joda.time.base
• org.joda.time.chrono
• org.joda.time.convert
• org.joda.time.field
• org.joda.time.format

For me the root of the problem was a number which I copied to use in a WHERE clause. The number had "invisible" symbol, at least for MySQL Workbench. I placed the number in the Chrome console it was clearly visible.

No.

I'm going against the crowd here, but bear with me. A single JS script is intended to be effectively single threaded, but this doesn't mean that it can't be interpreted differently.

Let's say you have the following code...

var list = [];
for (var i = 0; i < 10000; i++) {
  list[i] = i * i;
}

This is written with the expectation that by the end of the loop, the list must have 10000 entries which are the index squared, but the VM could notice that each iteration of the loop does not affect the other, and reinterpret using two threads.

First thread

for (var i = 0; i < 5000; i++) {
  list[i] = i * i;
}

Second thread

for (var i = 5000; i < 10000; i++) {
  list[i] = i * i;
}

I'm simplifying here, because JS arrays are more complicated then dumb chunks of memory, but if these two scripts are able to add entries to the array in a thread-safe way, then by the time both are done executing it'll have the same result as the single-threaded version.

While I'm not aware of any VM detecting parallelizable code like this, it seems likely that it could come into existence in the future for JIT VMs, since it could offer more speed in some situations.

Taking this concept further, it's possible that code could be annotated to let the VM know what to convert to multi-threaded code.

// like "use strict" this enables certain features on compatible VMs.
"use parallel";

var list = [];

// This string, which has no effect on incompatible VMs, enables threading on
// this loop.
"parallel for";
for (var i = 0; i < 10000; i++) {
  list[i] = i * i;
}

Since Web Workers are coming to Javascript, it's unlikely that this... uglier system will ever come into existence, but I think it's safe to say Javascript is single-threaded by tradition.

By 'return non-false', they mean to return any value which would not work out to boolean false. So you could return true, 1, 'non-false', or whatever else you can think up.

You should do it this way ideally

t = TemperatureData.objects.get(id=1)
t.value = 999
t.save(['value'])

This allow you to specify which column should be saved and rest are left as they currently are in database. (https://code.djangoproject.com/ticket/4102)!

None of these worked for me. I converted the first element to be part of a series (a single element series), and converted the second element also to be a series, and used append function.

l = ((pd.Series(<first element>)).append(pd.Series(<list of other elements>))).tolist()

I encountered this issue, but in my case the password for the 'phpmyadmin' user did not match the contents of /etc/phpmyadmin/config-db.php

Once I updated the password for the 'phpmyadmin' user the error went away.

These are the steps I took:

1. Log in to mysql as root: mysql -uroot -pYOUR_ROOT_PASS
2. Change to the 'mysql' db: use mysql;
3. Update the password for the 'phpmyadmin' user: UPDATE mysql.user SET Password=PASSWORD('YOUR_PASS_HERE') WHERE User='phpmyadmin' AND Host='localhost';
4. Flush privileges: FLUSH PRIVILEGES;

DONE!! It worked for me.

The best solution I found this to work for me guys after trying all the other solutions.... Basically i set the sScrollX to 200% then set the individual column widths to the required % that I wanted. The more columns that you have and the more space that you require then you need to raise the sScrollX %... The null means that I want those columns to retain the datatables auto width they have set in their code.

            $('#datatables').dataTable
            ({  
                "sScrollX": "200%", //This is what made my columns increase in size.
                "bScrollCollapse": true,
                "sScrollY": "320px",

                "bAutoWidth": false,
                "aoColumns": [
                    { "sWidth": "10%" }, // 1st column width 
                    { "sWidth": "null" }, // 2nd column width 
                    { "sWidth": "null" }, // 3rd column width
                    { "sWidth": "null" }, // 4th column width 
                    { "sWidth": "40%" }, // 5th column width 
                    { "sWidth": "null" }, // 6th column width
                    { "sWidth": "null" }, // 7th column width 
                    { "sWidth": "10%" }, // 8th column width 
                    { "sWidth": "10%" }, // 9th column width
                    { "sWidth": "40%" }, // 10th column width
                    { "sWidth": "null" } // 11th column width
                    ],
                "bPaginate": true,              
                "sDom": '<"H"TCfr>t<"F"ip>',

                {
                    "aButtons": [ "copy", "csv", "print", "xls", "pdf" ],
                    "sSwfPath": "copy_cvs_xls_pdf.swf"
                },
                "sPaginationType":"full_numbers",
                "aaSorting":[[0, "desc"]],
                "bJQueryUI":true    

            });

As I didn't find what I was looking for, I will share what I actually wanted to achieve when I ended in this question.

Scenario: I have 3 different API's with same possible response and therefore I would like to handle the completion and error handling of the promises in a single function. This is what I did:

1. Create a handler function:

  private handleHttpPromise = (promise: Promise<any>) => {
    promise
      .then((response: any) => {
        // do something with the response
        console.log(response);
      })
      .catch((error) => {
        // do something with the error
        console.log(error);
      });
  };

2. Send your promises to the created handler

  switch (method) {
    case 'get': {
      this.handleHttpPromise(apiService.get(url));
      break;
    }
    case 'post': {
      if (jsonData) {
        this.handleHttpPromise(apiService.post(url, jsonData));
      }
      break;
    }
    // (...)
  }

Solved 403: Forbidden when visiting localhost. Using ports 80,443,3308 (the later to handle conflict with MySQL Server installation) Windows 10, XAMPP 7.4.1, Apache 2.4.x My web files are in a separate folder.

httpd.conf - look for these lines and set it up where you have your files, mine is web folder.

DocumentRoot "C:/web"
<Directory "C:/web">

Changed these 2 lines.

<VirtualHost *:80>
 ServerAdmin [email protected]
 DocumentRoot "C:/web/project1"
 ServerName project1.localhost
 <Directory "C:/web/project1">
  Order allow,deny
  allow from all
 </Directory>
</VirtualHost>

to this

<VirtualHost *:80>
 ServerAdmin [email protected]
 DocumentRoot "C:/web/project1"
 ServerName project1.localhost
 <Directory "C:/web/project1">
  Require all granted
 </Directory>
</VirtualHost>

Add your details in your hosts file C:\Windows\System32\drivers\etc\hosts file

127.0.0.1 localhost
127.0.0.1 project1.localhost

Stop start XAMPP, and click Apache admin (or localhost) and the wonderful XAMPP dashboard now displays! And visit your project at project1.localhost

It is ||, for example:

select 'Mr ' || ename from emp;

The only "interesting" feature I can think of is that 'x' || null returns 'x', not null as you might perhaps expect.

Once you have the indexPath of your cell, you can do something like:

[self.tableView beginUpdates];
[self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPathOfYourCell, nil] withRowAnimation:UITableViewRowAnimationNone];
[self.tableView endUpdates]; 

In Xcode 4.6 and higher:

[self.tableView beginUpdates];
[self.tableView reloadRowsAtIndexPaths:@[indexPathOfYourCell] withRowAnimation:UITableViewRowAnimationNone];
[self.tableView endUpdates]; 

You can set whatever your like as animation effect, of course.

Instead of using display you could store the element 'off-screen' until you needed it, and then set its position to where you want it and transform it at the same time. This brings up a whole host of other design issues though, so your mileage may vary.

You probably wouldn't want to use display anyway, as you'd want the content to be accessible to screen readers, which for the most part try to obey rules for visibility - i.e., if it shouldn't be visible to the eye, it won't show up as content to the agent.

In new version of material 2 which its control name starts with mat prefix setErrors() doesn't work, instead Juila's answer can be changed to:

formData.form.controls['email'].markAsTouched();

I had this issue too, also running on an emulator.. The same message was showing up on Logcat, but it wasn't affecting the functionality of the app. But it was annoying, and I don't like seeing errors on the log that I don't understand.

Anyway, I got rid of the message by increasing the RAM on the emulator.

If you need to resume an scp transfer from local to remote, try with rsync:

rsync --partial --progress --rsh=ssh local_file user@host:remote_file

Short version, as pointed out by @aurelijus-rozenas:

rsync -P -e ssh local_file user@host:remote_file

In general the order of args for rsync is

rsync [options] SRC DEST

Like that:

$ command >>output 2>>error

Horizontal centering is as easy as:

text-align: center

Vertical centering when the container is a known height:

height: 100px;
line-height: 100px;
vertical-align: middle

Vertical centering when the container isn't a known height AND you can set the image in the background:

background: url(someimage) no-repeat center center;

Auth routes for Laravel 5.3 instead Auth::routes(). I hope it helps...

Route::group(['middleware' => ['web']], function() {

// Login Routes...
    Route::get('login', ['as' => 'login', 'uses' => 'Auth\LoginController@showLoginForm']);
    Route::post('login', ['as' => 'login.post', 'uses' => 'Auth\LoginController@login']);
    Route::post('logout', ['as' => 'logout', 'uses' => 'Auth\LoginController@logout']);

// Registration Routes...
    Route::get('register', ['as' => 'register', 'uses' => 'Auth\RegisterController@showRegistrationForm']);
    Route::post('register', ['as' => 'register.post', 'uses' => 'Auth\RegisterController@register']);

// Password Reset Routes...
    Route::get('password/reset', ['as' => 'password.reset', 'uses' => 'Auth\ForgotPasswordController@showLinkRequestForm']);
    Route::post('password/email', ['as' => 'password.email', 'uses' => 'Auth\ForgotPasswordController@sendResetLinkEmail']);
    Route::get('password/reset/{token}', ['as' => 'password.reset.token', 'uses' => 'Auth\ResetPasswordController@showResetForm']);
    Route::post('password/reset', ['as' => 'password.reset.post', 'uses' => 'Auth\ResetPasswordController@reset']);
});

So if you change some names of these routes, remember to also change in views the actions of the posts!

If a linked server is not allowed by your dba, you can use OPENROWSET. Books Online will provide the syntax you need.

There are two ways you can do this; with patch and with patch.object

Patch assumes that you are not directly importing the object but that it is being used by the object you are testing as in the following

#foo.py
def some_fn():
    return 'some_fn'

class Foo(object):
    def method_1(self):
        return some_fn()

#bar.py
import foo
class Bar(object):
    def method_2(self):
        tmp = foo.Foo()
        return tmp.method_1()

#test_case_1.py
import bar
from mock import patch

@patch('foo.some_fn')
def test_bar(mock_some_fn):
    mock_some_fn.return_value = 'test-val-1'
    tmp = bar.Bar()
    assert tmp.method_2() == 'test-val-1'
    mock_some_fn.return_value = 'test-val-2'
    assert tmp.method_2() == 'test-val-2'

If you are directly importing the module to be tested, you can use patch.object as follows:

#test_case_2.py
import foo
from mock import patch

@patch.object(foo, 'some_fn')
def test_foo(test_some_fn):
    test_some_fn.return_value = 'test-val-1'
    tmp = foo.Foo()
    assert tmp.method_1() == 'test-val-1'
    test_some_fn.return_value = 'test-val-2'
    assert tmp.method_1() == 'test-val-2'

In both cases some_fn will be 'un-mocked' after the test function is complete.

Edit: In order to mock multiple functions, just add more decorators to the function and add arguments to take in the extra parameters

@patch.object(foo, 'some_fn')
@patch.object(foo, 'other_fn')
def test_foo(test_other_fn, test_some_fn):
    ...

Note that the closer the decorator is to the function definition, the earlier it is in the parameter list.

For instance you can use

update tablename set datetimefield='19980223 14:23:05'
update tablename set datetimefield='02/23/1998 14:23:05'
update tablename set datetimefield='1998-12-23 14:23:05'
update tablename set datetimefield='23 February 1998 14:23:05'
update tablename set datetimefield='1998-02-23T14:23:05'

You need to be careful of day/month order since this will be language dependent when the year is not specified first. If you specify the year first then there is no problem; date order will always be year-month-day.

Page Control can be contained in Window Control but vice versa is not possible

You can use Page control within the Window control using NavigationWindow and Frame controls. Window is the root control that must be used to hold/host other controls (e.g. Button) as container. Page is a control which can be hosted in other container controls like NavigationWindow or Frame. Page control has its own goal to serve like other controls (e.g. Button). Page is to create browser like applications. So if you host Page in NavigationWindow, you will get the navigation implementation built-in. Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer).

WPF provides support for browser style navigation inside standalone application using Page class. User can create multiple pages, navigate between those pages along with data.There are multiple ways available to Navigate through one page to another page.

You can add the command in the /etc/rc.local script that is executed at the end of startup.

Write the command before exit 0. Anything written after exit 0 will never be executed.

def train_val_test_split(X, y, train_size, val_size, test_size):
    X_train_val, X_test, y_train_val, y_test = train_test_split(X, y, test_size = test_size)
    relative_train_size = train_size / (val_size + train_size)
    X_train, X_val, y_train, y_val = train_test_split(X_train_val, y_train_val,
                                                      train_size = relative_train_size, test_size = 1-relative_train_size)
    return X_train, X_val, X_test, y_train, y_val, y_test

Here we split data 2 times with sklearn's train_test_split

Try

private void cleanlistbox(object sender, EventArgs e)
{
   ListBox1.Items.Clear();
}

You could define a message to throw when a certain error occurs:

throw std::invalid_argument( "received negative value" );

or you could define it like this:

std::runtime_error greatScott("Great Scott!");          
double getEnergySync(int year) {                        
    if (year == 1955 || year == 1885) throw greatScott; 
    return 1.21e9;                                      
}                                                       

Typically, you would have a try ... catch block like this:

try {
// do something that causes an exception
}catch (std::exception& e){ std::cerr << "exception: " << e.what() << std::endl; }

When you want to show years and the remaining days:

var m = moment(d.birthday.date, "DD.MM.YYYY");
var years = moment().diff(m, 'years', false);
var days = moment().diff(m.add(years, 'years'), 'days', false);
alert(years + ' years, ' + days + ' days');

I needed to update my php from 5.3.8 to 5.3.29. (both Thread Safe) on Windows

Steps I did:

1. Back-up my initial php folder, under xampp.
2. Downloaded zip from here http://windows.php.net/download/#php-5.3-ts-VC9-x86
3. Unpack that zip into xampp folder.
4. Copied php.ini file from old php folder into new one.
5. Copied a couple of folders that I didn't have in the new php folder, from old one. For example: extras, which contained browscap.ini file (this one is needed)
6. Copied needed extensions, from old php ext folder into new php ext folder. I copied them manually, by checking list of extensions from php.ini file.
7. Copied also these files: php5apache2_2.dll, php5ts.dll

Hope that I covered everything.

Most probably these steps will not work if you change major versions of php, e.g. 5.3.x to 5.4.x, but for minor versions, it should work.

Also, a good way to see what's wrong... start command line and try to start httpd.exe, under xampp/apache/bin from there, it will list errors found.

The # tag lets you send your data to the same file. I see it as a three step process:

1. Query a DB to populate a from
2. Allow the user to change data in the form
3. Resubmit the data to the DB via the php script

With the method='#' you can do all of this in the same file.

After the submit query is executed the page will reload with the updated data from the DB.

Here are a couple possible solutions...

I have not tried all of these myself yet, but I will be trying them all soon.

Note: I do not have any personal or financial connection to any of these tools.

1) VB Script to EXE Converter (NOT Compiler): (Free)
vbs2exe.com.

The exe produced appears to be a true EXE.

From their website:

VBS to EXE is a free online converter that doesn't only convert your vbs files into exe but it also:

1- Encrypt your vbs file source code using 128 bit key.
2- Allows you to call win32 API
3- If you have troubles with windows vista especially when UAC is enabled then you may give VBS to EXE a try.
4- No need for wscript.exe to run your vbs anymore.
5- Your script is never saved to the hard disk like some others converters. it is a TRUE exe not an extractor.

This solution should work even if wscript/cscript is not installed on the computer.

Basically, this creates a true .EXE file. Inside the created .EXE is an "engine" that replaces wscript/cscript, and an encrypted copy of your VB Script code. This replacement engine executes your code IN MEMORY without calling wscript/cscript to do it.

2) Compile and Convert VBS to EXE...:
ExeScript

The current version is 3.5.

This is NOT a Free solution. They have a 15 day trial. After that, you need to buy a license for a hefty $44.96 (Home License/noncommercial), or $89.95 (Business License/commercial usage).

It seems to work in a similar way to the previous solution.

According to a forum post there:
Post: "A Exe file still need Windows Scripting Host (WSH) ??"

WSH is not required if "Compile" option was used, since ExeScript
implements it's own scripting host. ...

3) Encrypt the script with Microsoft's ".vbs to .vbe" encryption tool.

Apparently, this does not work for Windows 7/8, and it is possible there are ways to "decrypt" the .vbe file. At the time of writing this, I could not find a working link to download this. If I find one, I will add it to this answer.

To zoom on Eclipse you can use : CTRL SHIFT + OR -

Try this:

Private Sub CreateSheet()
    Dim ws As Worksheet
    Set ws = ThisWorkbook.Sheets.Add(After:= _
             ThisWorkbook.Sheets(ThisWorkbook.Sheets.Count))
    ws.Name = "Tempo"
End Sub

Or use a With clause to avoid repeatedly calling out your object

Private Sub CreateSheet()
    Dim ws As Worksheet
    With ThisWorkbook
        Set ws = .Sheets.Add(After:=.Sheets(.Sheets.Count))
        ws.Name = "Tempo"
    End With
End Sub

Above can be further simplified if you don't need to call out on the same worksheet in the rest of the code.

Sub CreateSheet()
    With ThisWorkbook
        .Sheets.Add(After:=.Sheets(.Sheets.Count)).Name = "Temp"
    End With
End Sub

DONT: This is not a solution!

My first approach was:

public int longToInt(long theLongOne) {
  return Long.valueOf(theLongOne).intValue();
}

But that merely just casts the long to an int, potentially creating new Long instances or retrieving them from the Long pool.

The drawbacks

1. Long.valueOf creates a new Long instance if the number is not within Long's pool range [-128, 127].

2. The intValue implementation does nothing more than:

   return (int)value;
   

So this can be considered even worse than just casting the long to int.

For those seeking for a solution that works within a flexible parent container with a children that is flexible in both dimensions. eg. navbar buttons.

//the parent (example of what it may be)
div {
  display:flex;
  width: 100%;
}

//The children
a {
  display: inline-block;
}

//text wrapper
span {
  display: table-caption;
}

I was using python interpolation and forgot the ending s character:

a = dict(foo='bar')
print("What comes after foo? %(foo)" % a) # Should be %(foo)s

Watch those typos.

It might be late, but for any other person who may get such an issue in future, for any connections you want to make to the server (in this case the machine that hosts the web application, regardless if it is iis or xampp) you need to allow connection or traffic through the specific port that will be used in the firewall

1. Go to Windows Firewall -> Advanced settings
2. Click Inbound Rules -> Then New Rule
3. Select Port -> Next
4. Specific local ports -> Add the Port you want to allow
5. Allow All Connections
6. Enter a name and a description for to help you remember later on

For completeness, in Numpy there are four maximum related functions. They fall into two different categories:

• np.amax/np.max, np.nanmax: for single array order statistics
• and np.maximum, np.fmax: for element-wise comparison of two arrays

I. For single array order statistics

NaNs propagator np.amax/np.max and its NaN ignorant counterpart np.nanmax.

• np.max is just an alias of np.amax, so they are considered as one function.

  >>> np.max.__name__
  'amax'
  >>> np.max is np.amax
  True
  

• np.max propagates NaNs while np.nanmax ignores NaNs.

  >>> np.max([np.nan, 3.14, -1])
  nan
  >>> np.nanmax([np.nan, 3.14, -1])
  3.14
  

II. For element-wise comparison of two arrays

NaNs propagator np.maximum and its NaNs ignorant counterpart np.fmax.

• Both functions require two arrays as the first two positional args to compare with.

  # x1 and x2 must be the same shape or can be broadcast
  np.maximum(x1, x2, /, ...);
  np.fmax(x1, x2, /, ...)
  

• np.maximum propagates NaNs while np.fmax ignores NaNs.

  >>> np.maximum([np.nan, 3.14, 0], [np.NINF, np.nan, 2.72])
  array([ nan,  nan, 2.72])
  >>> np.fmax([np.nan, 3.14, 0], [np.NINF, np.nan, 2.72])
  array([-inf, 3.14, 2.72])
  

• The element-wise functions are np.ufunc(Universal Function), which means they have some special properties that normal Numpy function don't have.

  >>> type(np.maximum)
  <class 'numpy.ufunc'>
  >>> type(np.fmax)
  <class 'numpy.ufunc'>
  >>> #---------------#
  >>> type(np.max)
  <class 'function'>
  >>> type(np.nanmax)
  <class 'function'>
  

And finally, the same rules apply to the four minimum related functions:

• np.amin/np.min, np.nanmin;
• and np.minimum, np.fmin.

In my application,above javascript function didnt work,because i had many procrosses inside one page.so following code worked for me hope it helps you guys.

  function redirection()
        {
           <?php $send=$_SERVER['HTTP_REFERER'];?> 
            var redirect_to="<?php echo $send;?>";             
            window.location = redirect_to;

        }

htmlspecialchars function is the best solution fellows. Today I was searching for how to insert strings with special characters and the google thrown so many Stackoverflow listings.None of them provided me solution. I found it in w3schools page. Yes I could solve my problem by using this function like this:

$abc = $POST['xyz'];

$abc = htmlspecialchars($abc);

You may want one of these, so to correspond to the Bootstrap layout:

<div class="col-xs-12">
    <hr >
</div>

<!-- or -->

<div class="col-xs-12">
    <hr style="border-style: dashed; border-top-width: 2px;">
</div>

<!-- or -->

<div class="col-xs-12">
    <hr class="col-xs-1" style="border-style: dashed; border-top-width: 2px;">
</div>

Without a DIV grid element included, layout may brake on different devices.

I assume the question is already answered. If above solution doesn't help in solving the issue then can use below to solve the issue.

The issue occurs if sometimes your maven user settings is not reflecting correct settings.xml file.

To update the settings file go to Windows > Preferences > Maven > User Settings and update the settings.xml to it correct location.

Once this is doen re-build the project, these should solve the issue. Thanks.

I've used various methods for scripting telnet sessions under unix, but the simplest one is probably a sequence of echo and sleep commands, with their output piped into telnet. Piping the output into another command is also a possibility.

Silly example

(echo password; echo "show ip route"; sleep 1; echo "quit" ) | telnet myrouter

This (basicallly) retrieves the routing table of a Cisco router.

For AWS if the user is ubuntu use the following to connect to remote server.

chmod 400 mykey.pem

ssh -i mykey.pem ubuntu@your-ip

From LDAP, there is not a query method to determine an empty string.

The best practice would be to scrub your data inputs to LDAP as an empty or null value in LDAP is no value at all.

To determine this you would need to query for all with a value (manager=*) and then use code to determine the ones that were a "space" or null value.

And as Terry said, storing an empty or null value in an attribute of DN syntax is wrong.

Some LDAP server implementations will not permit entering a DN where the DN entry does not exist.

Perhaps, you could, if your DN's are consistent, use something like:

(&(!(manager=cn*))(manager=*))

This should return any value of manager where there was a value for manager and it did not start with "cn".

However, some LDAP implementations will not allow sub-string searches on DN syntax attributes.

The top 2 answers (from Adam Robinson and Andrejs Cainikovs) are kinda, sorta correct, in that they do technically work, but their explanations are wrong and so could be misleading in many cases. For example, while the SQL_Latin1_General_CP1_CI_AS collation will work in many cases, it should not be assumed to be the appropriate case-insensitive collation. In fact, given that the O.P. is working in a database with a case-sensitive (or possibly binary) collation, we know that the O.P. isn't using the collation that is the default for so many installations (especially any installed on an OS using US English as the language): SQL_Latin1_General_CP1_CI_AS. Sure, the O.P. could be using SQL_Latin1_General_CP1_CS_AS, but when working with VARCHAR data, it is important to not change the code page as it could lead to data loss, and that is controlled by the locale / culture of the collation (i.e. Latin1_General vs French vs Hebrew etc). Please see point # 9 below.

The other four answers are wrong to varying degrees.

I will clarify all of the misunderstandings here so that readers can hopefully make the most appropriate / efficient choices.

1. Do not use UPPER(). That is completely unnecessary extra work. Use a COLLATE clause. A string comparison needs to be done in either case, but using UPPER() also has to check, character by character, to see if there is an upper-case mapping, and then change it. And you need to do this on both sides. Adding COLLATE simply directs the processing to generate the sort keys using a different set of rules than it was going to by default. Using COLLATE is definitely more efficient (or "performant", if you like that word :) than using UPPER(), as proven in this test script (on PasteBin).

   There is also the issue noted by @Ceisc on @Danny's answer:

   In some languages case conversions do not round-trip. i.e. LOWER(x) != LOWER(UPPER(x)).

   The Turkish upper-case "I" is the common example.

2. No, collation is not a database-wide setting, at least not in this context. There is a database-level default collation, and it is used as the default for altered and newly created columns that do not specify the COLLATE clause (which is likely where this common misconception comes from), but it does not impact queries directly unless you are comparing string literals and variables to other string literals and variables, or you are referencing database-level meta-data.

3. No, collation is not per query.

4. Collations are per predicate (i.e. something operand something) or expression, not per query. And this is true for the entire query, not just the WHERE clause. This covers JOINs, GROUP BY, ORDER BY, PARTITION BY, etc.

5. No, do not convert to VARBINARY (e.g.convert(varbinary, myField) = convert(varbinary, 'sOmeVal')) for the following reasons:

   1. that is a binary comparison, which is not case-insensitive (which is what this question is asking for)
   2. if you do want a binary comparison, use a binary collation. Use one that ends with _BIN2 if you are using SQL Server 2008 or newer, else you have no choice but to use one that ends with _BIN. If the data is NVARCHAR then it doesn't matter which locale you use as they are all the same in that case, hence Latin1_General_100_BIN2 always works. If the data is VARCHAR, you must use the same locale that the data is currently in (e.g. Latin1_General, French, Japanese_XJIS, etc) because the locale determines the code page that is used, and changing code pages can alter the data (i.e. data loss).
   3. using a variable-length datatype without specifying the size will rely on the default size, and there are two different defaults depending on the context where the datatype is being used. It is either 1 or 30 for string types. When used with CONVERT() it will use the 30 default value. The danger is, if the string can be over 30 bytes, it will get silently truncated and you will likely get incorrect results from this predicate.
   4. Even if you want a case-sensitive comparison, binary collations are not case-sensitive (another very common misconception).

6. No, LIKE is not always case-sensitive. It uses the collation of the column being referenced, or the collation of the database if a variable is compared to a string literal, or the collation specified via the optional COLLATE clause.

7. LCASE is not a SQL Server function. It appears to be either Oracle or MySQL. Or possibly Visual Basic?

8. Since the context of the question is comparing a column to a string literal, neither the collation of the instance (often referred to as "server") nor the collation of the database have any direct impact here. Collations are stored per each column, and each column can have a different collation, and those collations don't need to be the same as the database's default collation or the instance's collation. Sure, the instance collation is the default for what a newly created database will use as its default collation if the COLLATE clause wasn't specified when creating the database. And likewise, the database's default collation is what an altered or newly created column will use if the COLLATE clause wasn't specified.

9. You should use the case-insensitive collation that is otherwise the same as the collation of the column. Use the following query to find the column's collation (change the table's name and schema name):

   SELECT col.*
   FROM   sys.columns col
   WHERE  col.[object_id] = OBJECT_ID(N'dbo.TableName')
   AND    col.[collation_name] IS NOT NULL;
   

   Then just change the _CS to be _CI. So, Latin1_General_100_CS_AS would become Latin1_General_100_CI_AS.

   If the column is using a binary collation (ending in _BIN or _BIN2), then find a similar collation using the following query:

   SELECT *
   FROM   sys.fn_helpcollations() col
   WHERE  col.[name] LIKE N'{CurrentCollationMinus"_BIN"}[_]CI[_]%';
   

   For example, assuming the column is using Japanese_XJIS_100_BIN2, do this:

   SELECT *
   FROM   sys.fn_helpcollations() col
   WHERE  col.[name] LIKE N'Japanese_XJIS_100[_]CI[_]%';

Converting HTML for Plain Text emailing keeping hyperlinks (a href) intact

The above function posted by hypoxide works fine, but I was after something that would basically convert HTML created in a Web RichText editor (for example FCKEditor) and clear out all HTML but leave all the Links due the fact that I wanted both the HTML and the plain text version to aid creating the correct parts to an STMP email (both HTML and plain text).

After a long time of searching Google myself and my collegues came up with this using the regex engine in Javascript:

str='this string has <i>html</i> code i want to <b>remove</b><br>Link Number 1 -><a href="http://www.bbc.co.uk">BBC</a> Link Number 1<br><p>Now back to normal text and stuff</p>
';
str=str.replace(/<br>/gi, "\n");
str=str.replace(/<p.*>/gi, "\n");
str=str.replace(/<a.*href="(.*?)".*>(.*?)<\/a>/gi, " $2 (Link->$1) ");
str=str.replace(/<(?:.|\s)*?>/g, "");

the str variable starts out like this:

this string has <i>html</i> code i want to <b>remove</b><br>Link Number 1 -><a href="http://www.bbc.co.uk">BBC</a> Link Number 1<br><p>Now back to normal text and stuff</p>

and then after the code has run it looks like this:-

this string has html code i want to remove
Link Number 1 -> BBC (Link->http://www.bbc.co.uk)  Link Number 1


Now back to normal text and stuff

As you can see the all the HTML has been removed and the Link have been persevered with the hyperlinked text is still intact. Also I have replaced the <p> and <br> tags with \n (newline char) so that some sort of visual formatting has been retained.

To change the link format (eg. BBC (Link->http://www.bbc.co.uk) ) just edit the $2 (Link->$1), where $1 is the href URL/URI and the $2 is the hyperlinked text. With the links directly in body of the plain text most SMTP Mail Clients convert these so the user has the ability to click on them.

Hope you find this useful.

As @PavelAnossov answered, the canonical answer, use the word_tokenize function in nltk:

from nltk import word_tokenize
sent = "This is my text, this is a nice way to input text."
word_tokenize(sent)

If your sentence is truly simple enough:

Using the string.punctuation set, remove punctuation then split using the whitespace delimiter:

import string
x = "This is my text, this is a nice way to input text."
y = "".join([i for i in x if not in string.punctuation]).split(" ")
print y

// trans.php
function begin(){

mysql_connect("localhost","Dude1", "SuperSecret") or die(mysql_error());

I like best answer but if it is an empty string it returns true. So here's a fix:

function isJSON(MyTestStr){
    try {
        var MyJSON = JSON.stringify(MyTestStr);
        var json = JSON.parse(MyJSON);
        if(typeof(MyTestStr) == 'string')
            if(MyTestStr.length == 0)
                return false;
    }
    catch(e){
        return false;
    }
    return true;
}

Floats, by nature, are imprecise and always have neat rounding "issues". If precision is important then you might consider refactoring your application to use Decimal or BigDecimal.

Yes, floats are computationally faster than decimals because of the on processor support. However, do you want fast or accurate?

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.

If you have accidentally removed DLL file from php/ext folder, just add it back (get the copy from XAMPP zip archive - its downloadable).

If you have deleted the accompanying INI configuration line from php.ini file, add it back as well:

extension=php_mbstring.dll

Also, ensure to restart your webserver (Apache) using XAMPP control panel.

Additional Info on Enabling PHP Extensions

• install extension (e.g. put php_mbstring.dll into /XAMPP/php/ext directory)
• in php.ini, ensure extension directory specified (e.g. extension_dir = "ext")
• ensure correct build of DLL file (e.g. 32bit thread-safe VC9 only works with DLL files built using exact same tools and configuration: 32bit thread-safe VC9)
• ensure PHP API versions match (If not, once you restart the webserver you will receive related error.)

This will give you all the elements as a list.

    mvv_count_df.select('mvv').toPandas()['mvv']

Editing or overriding the row in Twitter bootstrap is a bad idea, because this is a core part of the page scaffolding and you will need rows without a top margin.

To solve this, instead create a new class "top-buffer" that adds the standard margin that you need.

.top-buffer { margin-top:20px; }

And then use it on the row divs where you need a top margin.

<div class="row top-buffer"> ...

datePicker's onSelect equivalent is the dateSelected event.

$(function() {
    $('.date-pick').datePicker( {
        selectWeek: true,
        inline: true,
        startDate: '01/01/2000',
        firstDay: 1,
    }).bind('dateSelected', function(e, selectedDate, $td) {
        alert(selectedDate);
    });
});

This page has a good example showing the dateSelected event and other events being bound.

You can use Pandas.

I create the DataFrame:

import pandas as pd
df = pd.DataFrame([[1, 2,5], [5,4, 5], [7,7, 8], [7,6,9]],
                  index=['Jane', 'Peter','Alex','Ann'],
                  columns=['Test_1', 'Test_2', 'Test_3'])

The DataFrame:

       Test_1  Test_2  Test_3
Jane        1       2       5
Peter       5       4       5
Alex        7       7       8
Ann         7       6       9

To select one or more columns by name:

df[['Test_1', 'Test_3']]

       Test_1  Test_3
Jane        1       5
Peter       5       5
Alex        7       8
Ann         7       9

You can also use:

df.Test_2

And you get column Test_2:

Jane     2
Peter    4
Alex     7
Ann      6

You can also select columns and rows from these rows using .loc(). This is called "slicing". Notice that I take from column Test_1 to Test_3:

df.loc[:, 'Test_1':'Test_3']

The "Slice" is:

       Test_1  Test_2  Test_3
Jane        1       2       5
Peter       5       4       5
Alex        7       7       8
Ann         7       6       9

And if you just want Peter and Ann from columns Test_1 and Test_3:

df.loc[['Peter', 'Ann'], ['Test_1', 'Test_3']]

You get:

       Test_1  Test_3
Peter       5       5
Ann         7       9

Doing unions in MongoDB in a 'SQL UNION' fashion is possible using aggregations along with lookups, in a single query. Here is an example I have tested that works with MongoDB 4.0:

// Create employees data for testing the union.
db.getCollection('employees').insert({ name: "John", type: "employee", department: "sales" });
db.getCollection('employees').insert({ name: "Martha", type: "employee", department: "accounting" });
db.getCollection('employees').insert({ name: "Amy", type: "employee", department: "warehouse" });
db.getCollection('employees').insert({ name: "Mike", type: "employee", department: "warehouse"  });

// Create freelancers data for testing the union.
db.getCollection('freelancers').insert({ name: "Stephany", type: "freelancer", department: "accounting" });
db.getCollection('freelancers').insert({ name: "Martin", type: "freelancer", department: "sales" });
db.getCollection('freelancers').insert({ name: "Doug", type: "freelancer", department: "warehouse"  });
db.getCollection('freelancers').insert({ name: "Brenda", type: "freelancer", department: "sales"  });

// Here we do a union of the employees and freelancers using a single aggregation query.
db.getCollection('freelancers').aggregate( // 1. Use any collection containing at least one document.
  [
    { $limit: 1 }, // 2. Keep only one document of the collection.
    { $project: { _id: '$$REMOVE' } }, // 3. Remove everything from the document.

    // 4. Lookup collections to union together.
    { $lookup: { from: 'employees', pipeline: [{ $match: { department: 'sales' } }], as: 'employees' } },
    { $lookup: { from: 'freelancers', pipeline: [{ $match: { department: 'sales' } }], as: 'freelancers' } },

    // 5. Union the collections together with a projection.
    { $project: { union: { $concatArrays: ["$employees", "$freelancers"] } } },

    // 6. Unwind and replace root so you end up with a result set.
    { $unwind: '$union' },
    { $replaceRoot: { newRoot: '$union' } }
  ]);

Here is the explanation of how it works:

1. Instantiate an aggregate out of any collection of your database that has at least one document in it. If you can't guarantee any collection of your database will not be empty, you can workaround this issue by creating in your database some sort of 'dummy' collection containing a single empty document in it that will be there specifically for doing union queries.

2. Make the first stage of your pipeline to be { $limit: 1 }. This will strip all the documents of the collection except the first one.

3. Strip all the fields of the remaining document by using a $project stage:

   { $project: { _id: '$$REMOVE' } }
   

4. Your aggregate now contains a single, empty document. It's time to add lookups for each collection you want to union together. You may use the pipeline field to do some specific filtering, or leave localField and foreignField as null to match the whole collection.

   { $lookup: { from: 'collectionToUnion1', pipeline: [...], as: 'Collection1' } },
   { $lookup: { from: 'collectionToUnion2', pipeline: [...], as: 'Collection2' } },
   { $lookup: { from: 'collectionToUnion3', pipeline: [...], as: 'Collection3' } }
   

5. You now have an aggregate containing a single document that contains 3 arrays like this:

   {
       Collection1: [...],
       Collection2: [...],
       Collection3: [...]
   }
   

   You can then merge them together into a single array using a $project stage along with the $concatArrays aggregation operator:

   {
     "$project" :
     {
       "Union" : { $concatArrays: ["$Collection1", "$Collection2", "$Collection3"] }
     }
   }
   

6. You now have an aggregate containing a single document, into which is located an array that contains your union of collections. What remains to be done is to add an $unwind and a $replaceRoot stage to split your array into separate documents:

   { $unwind: "$Union" },
   { $replaceRoot: { newRoot: "$Union" } }
   

7. Voilà. You now have a result set containing the collections you wanted to union together. You can then add more stages to filter it further, sort it, apply skip() and limit(). Pretty much anything you want.

Yes you need javascript. The simplest way is to just put this at the bottom of your HTML page:

<script type="text/javascript">
alert("Hello world");
</script>

There are more preferred methods, like using jQuery's ready function, but this method will work.

Here is a solution to get the country based on an international phone number without using the Google library.

Let me explain first why it is so difficult to figure out the country. The country code of few countries is 1 digit, 2, 3 or 4 digits. That would be simple enough. But the country code 1 is not just used for US, but also for Canada and some smaller places:

1339 USA
1340 Virgin Islands (Caribbean Islands)
1341 USA
1342 not used
1343 Canada

Digits 2..4 decide, if it is US or Canada or ... There is no easy way to figure out the country, like the first xxx are Canada, the rest US.

For my code, I defined a class which holds information for ever digit:

public class DigitInfo {
  public char Digit;
  public Country? Country;
  public DigitInfo?[]? Digits;
}

A first array holds the DigitInfos for the first digit in the number. The second digit is used as an index into DigitInfo.Digits. One travels down that Digits chain, until Digits is empty. If Country is defined (i.e. not null) that value gets returned, otherwise any Country defined earlier gets returned:

country code 1: byPhone[1].Country is US  
country code 1236: byPhone[1].Digits[2].Digits[3].Digits[6].Country is Canada  
country code 1235: byPhone[1].Digits[2].Digits[3].Digits[5].Country is null. Since   
                   byPhone[1].Country is US, also 1235 is US, because no other   
                   country was found in the later digits

Here is the method which returns the country based on the phone number:

/// <summary>
/// Returns the Country based on an international dialing code.
/// </summary>
public static Country? GetCountry(ReadOnlySpan<char> phoneNumber) {
  if (phoneNumber.Length==0) return null;

  var isFirstDigit = true;
  DigitInfo? digitInfo = null;
  Country? country = null;
  foreach (var digitChar in phoneNumber) {
    var digitIndex = digitChar - '0';
    if (isFirstDigit) {
      isFirstDigit = false;
      digitInfo = ByPhone[digitIndex];
    } else {
      if (digitInfo!.Digits is null) return country;

      digitInfo = digitInfo.Digits[digitIndex];
    }
    if (digitInfo is null) return country;

    country = digitInfo.Country??country;
  }
  return country;
}

The rest of the code (digitInfos for every country of the world, test code, ...) is too big to be posted here, but it can be found on Github: https://github.com/PeterHuberSg/WpfWindowsLib/blob/master/WpfWindowsLib/CountryCode.cs

The code is part of a WPF TextBox and the library contains also other controls for email addresses, etc. A more detailed description is on CodeProject: International Phone Number Validation Explained in Detail

            ->where(function($query) use ($name) {
                $query->where('name', 'like', '%' . $name . '%')
                ->orWhere('company_name', 'like', '%' . $name . '%');
            })
            ->Where('status', '=', 1)
            ->limit(20)
            ->get();

This is due because of the items id being the same. On change fires only if a different item id is detected on select.

So you have 2 options: First is to make sure that each items have a unique id when retrieving datas from ajax.

Second is to trigger a rand number at formatSelection for the selected item.

function getRandomInt(min, max) {
    return Math.floor(Math.random() * (max - min + 1)) + min;
}

.

formatSelection: function(item) {item.id =getRandomInt(1,200)}

If using win7 64 bit OS:

After installing the latest JDK make sure you copy the jre folder from the install location {C:\Program Files\Java\jdk1.7.0_40} directly to your eclipse folder as even pathing it apparently does nothing on win7.

edit:

Actual jdk version number on folder name will vary as newer versions are released

You can easily use Node.JS in your web app only for real-time communication. Node.JS is really powerful when it's about WebSockets. Therefore "PHP Notifications via Node.js" would be a great concept.

See this example: Creating a Real-Time Chat App with PHP and Node.js

That's the same behavior I've seen: iframe's load() will fire first on an empty iframe, then the second time when your page is loaded.

Edit: Hmm, interesting. You could increment a counter in your event handler, and a) ignore the first load event, or b) ignore any duplicate load event.

You can not get hive version from command line.

You can checkout hadoop version as mentioned by Dave.

Also if you are using cloudera distribution, then look directly at the libs:

ls /usr/lib/hive/lib/ and check for hive library

hive-hwi-0.7.1-cdh3u3.jar

You can also check the compatible versions here:

http://www.cloudera.com/content/cloudera/en/documentation/cdh5/v5-1-x/CDH-Version-and-Packaging-Information/CDH-Version-and-Packaging-Information.html

NP stands for Non-deterministic Polynomial time.

This means that the problem can be solved in Polynomial time using a Non-deterministic Turing machine (like a regular Turing machine but also including a non-deterministic "choice" function). Basically, a solution has to be testable in poly time. If that's the case, and a known NP problem can be solved using the given problem with modified input (an NP problem can be reduced to the given problem) then the problem is NP complete.

The main thing to take away from an NP-complete problem is that it cannot be solved in polynomial time in any known way. NP-Hard/NP-Complete is a way of showing that certain classes of problems are not solvable in realistic time.

Edit: As others have noted, there are often approximate solutions for NP-Complete problems. In this case, the approximate solution usually gives an approximation bound using special notation which tells us how close the approximation is.

Your code won't work because you haven't assigned anything to n before you first use it. Try this:

def oracle():
    n = None
    while n != 'Correct':
        # etc...

A more readable approach is to move the test until later and use a break:

def oracle():
    guess = 50

    while True:
        print 'Current number = {0}'.format(guess)
        n = raw_input("lower, higher or stop?: ")
        if n == 'stop':
            break
        # etc...

Also input in Python 2.x reads a line of input and then evaluates it. You want to use raw_input.

Note: In Python 3.x, raw_input has been renamed to input and the old input method no longer exists.

Had the same problem, but solved it in a different way. It might not be the best solution, but its a solution.

in app.config:

<add key="errorMailFirst" value="[email protected]"/>
<add key="errorMailSeond" value="[email protected]"/>

Then in my configuration wrapper class, I add a method to search keys.

        public List<string> SearchKeys(string searchTerm)
        {
            var keys = ConfigurationManager.AppSettings.Keys;
            return keys.Cast<object>()
                       .Where(key => key.ToString().ToLower()
                       .Contains(searchTerm.ToLower()))
                       .Select(key => ConfigurationManager.AppSettings.Get(key.ToString())).ToList();
        }

For anyone reading this, i agree that creating your own custom configuration section is cleaner, and more secure, but for small projects, where you need something quick, this might solve it.

Best solution is to use this jquery plugin:

https://github.com/jmosbech/StickyTableHeaders

This plugin worked great for us and we tried a lot other solutions. We tested it in IE, Chrome and Firefox

While this question is quite old I just want to add another possibility of doing a merge while keeping keys.

Besides adding key/values to existing arrays using the + sign you could do an array_replace.

$a = array('foo' => 'bar', 'some' => 'string');
$b = array(42 => 'answer to the life and everything', 1337 => 'leet');

$merged = array_replace($a, $b);

The result will be:

Array
(
  [foo] => bar
  [some] => string
  [42] => answer to the life and everything
  [1337] => leet
)

Same keys will be overwritten by the latter array.
There is also an array_replace_recursive, which do this for subarrays, too.

Live example on 3v4l.org

Here you go. I have used this code with UIView, though. You should be able to make those adjustments for scrollview.

    func addKeyboardNotifications() {
        NotificationCenter.default.addObserver(self,
                                               selector: #selector(keyboardWillShow(notification:)),
                                               name: NSNotification.Name.UIKeyboardWillShow, object: nil)
        NotificationCenter.default.addObserver(self,
                                               selector: #selector(keyboardWillHide(notification:)),
                                               name: NSNotification.Name.UIKeyboardWillHide, object: nil)
    }

    func keyboardWillShow(notification: NSNotification) {

        if let keyboardSize = (notification.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
            let duration = notification.userInfo![UIKeyboardAnimationDurationUserInfoKey] as! Double
// if using constraints            
// bottomViewBottomSpaceConstraint.constant = keyboardSize.height
self.view.frame.origin.y -= keyboardSize.height
            UIView.animate(withDuration: duration) {
                self.view.layoutIfNeeded()
            }
        }
    }
    func keyboardWillHide(notification: NSNotification) {

        let duration = notification.userInfo![UIKeyboardAnimationDurationUserInfoKey] as! Double
//if using constraint
//        bottomViewBottomSpaceConstraint.constant = 0
self.view.frame.origin.y = 0
        UIView.animate(withDuration: duration) {
            self.view.layoutIfNeeded()
        }
    }

Don't forget to remove notifications at right place.

func removeKeyboardNotifications() {
    NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillShow, object: nil)
    NotificationCenter.default.removeObserver(self, name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

The const means that the method promises not to alter any members of the class. You'd be able to execute the object's members that are so marked, even if the object itself were marked const:

const foobar fb;
fb.foo();

would be legal.

See How many and which are the uses of “const” in C++? for more information.

datetime.datetime.fromtimestamp will do, if you know the time zone, you could produce the same output as with time.gmtime

>>> datetime.datetime.fromtimestamp(1284286794)
datetime.datetime(2010, 9, 12, 11, 19, 54)

or

>>> datetime.datetime.utcfromtimestamp(1284286794)
datetime.datetime(2010, 9, 12, 10, 19, 54)

I had a similar issue where one of the arrays was modified. I was using it for $httpBackend, and the returned object from that was actually a $promise object containing the array (not an Array object).

You can create a jasmine matcher to match the array by creating a toBeArray function:

beforeEach(function() {
  'use strict';
  this.addMatchers({
    toBeArray: function(array) {
      this.message = function() {
        return "Expected " + angular.mock.dump(this.actual) + " to be array " + angular.mock.dump(array) + ".";
      };
      var arraysAreSame = function(x, y) {
         var arraysAreSame = true;
         for(var i; i < x.length; i++)
            if(x[i] !== y[i])
               arraysAreSame = false;
         return arraysAreSame;
      };
      return arraysAreSame(this.actual, array);
    }
  });
});

And then just use it in your tests like the other jasmine matchers:

it('should compare arrays properly', function() {
  var array1, array2;
  /* . . . */
  expect(array1[0]).toBe(array2[0]);
  expect(array1).toBeArray(array2);
});

my question: while WHAT is True?

While True is True.

The while loop will run as long as the conditional expression evaluates to True.

Since True always evaluates to True, the loop will run indefinitely, until something within the loop returns or breaks.

On my AIX system, I tried

nohup -p  processid>

This worked well. It continued to run my process even after closing terminal windows. We have ksh as default shell so the bg and disown commands didn't work.

... What about using Apache's FileFilters from: org.apache.commons.io?

just like:

 import org.apache.commons.io.filefilter.FileFileFilter;
 import org.apache.commons.io.filefilter.WildcardFileFilter;

 ...

 File dir = new File(".");

 String[] filters = { "*.txt"};
 IOFileFilter wildCardFilter = new WildcardFileFilter(filters, IOCase.INSENSITIVE);

 String[] files = dir.list( wildCardFilter );
 for ( int i = 0; i < files.length; i++ ) {
     System.out.println(files[i]);
 }

You can use this :

$this->db->select('*');
$this->db->from('mytable');
$this->db->where(name,'Joe');
$bind = array('boss', 'active');
$this->db->where_in('status', $bind);

You can use nested.

There are tow function one is openTab() and another is closeMobileMenue(), Firstly we call openTab() and call another function inside closeMobileMenue().

function openTab() {
    window.open('https://play.google.com/store/apps/details?id=com.drishya');
    closeMobileMenue()   //After open new tab, Nav Menue will close.  
}

onClick={openTab}

Standard PHP objects

The best way to provide PHP variables to JavaScript is json_encode. When using Blade you can do it like following:

<script>
    var bool = {!! json_encode($bool) !!};
    var int = {!! json_encode($int) !!};
    /* ... */
    var array = {!! json_encode($array_without_keys) !!};
    var object = {!! json_encode($array_with_keys) !!};
    var object = {!! json_encode($stdClass) !!};
</script>

• Displaying unescaped data - Laravel docs
• json_encode - PHP docs

There is also a Blade directive for decoding to JSON. I'm not sure since which version of Laravel but in 5.5 it is available. Use it like following:

<script>
    var array = @json($array);
</script>

• Blade Templates - Laravel 5.5 docs

Jsonable's

When using Laravel objects e.g. Collection or Model you should use the ->toJson() method. All those classes that implements the \Illuminate\Contracts\Support\Jsonable interface supports this method call. The call returns automatically JSON.

<script>
    var collection = {!! $collection->toJson() !!};
    var model = {!! $model->toJson() !!};
</script>

When using Model class you can define the $hidden property inside the class and those will be filtered in JSON. The $hidden property, as its name describs, hides sensitive content. So this mechanism is the best for me. Do it like following:

class User extends Model
{
    /* ... */

    protected $hidden = [
        'password', 'ip_address' /* , ... */
    ];

    /* ... */
}

And somewhere in your view

<script>
    var user = {!! $user->toJson() !!};
</script>

• Serializing to JSON - Laravel docs

This is an alternate solution/fix... In FF3, You can retrieve file's full path in a textbox instead of file browse box. And that too... By drag/dropping the file!

You can drag drop your file into a text box in your html page. and it will display the file's complete path. This data can transferred to your server easily or manipulate them.

All you have to do is to use the extension DragDropUpload

http://www.teslacore.it/wiki/index.php?title=DragDropUpload

This extension will helps you in drag dropping files into your File Browse (Input file) box. But still you wont able to get the file full path, If you try to retrieve.

So, I tweaked this extension a little. In the way I can drag drop a file on to any "Text Input" box and get the file full path. And thus I can able to get the file full path in FF3 Firefox 3.

For me the answer was to cd into the root directory of the app before running heroku create or git push heroku master

Yes, you can use Yarn or NPM to edit your package.json.

yarn upgrade [package | package@tag | package@version | @scope/]... [--ignore-engines] [--pattern]

Something like:

yarn upgrade react@^16.0.0

Then I'd see what warns or errors out and then run yarn upgrade [package]. No need to edit the file manually. Can do everything from the CLI.

Or just run yarn upgrade to update all packages to latest, probably a bad idea for a large project. APIs may change, things may break.

Alternatively, with NPM run npm outdated to see what packages will be affected. Then

npm update

https://yarnpkg.com/lang/en/docs/cli/upgrade/

The package manager (“installer”) has a design problem: it can’t distinguish between a bunch of possible errors and regularly comes up with the “insufficient storage” excuse.

The first steps are done: identify it’s an install problem (1.) and not related to storage shortage (2.)

3. It happens on the console (pm install file.apk), with Google Play, other markets and manual GUI-install (for example, “clicking” on a downloaded APK file); it is not a download issue, ...
4. Packages end up entirely on the /data partition -or- mostly on the SD card (and a little on /data). – Both places show enough space as indicated by the original poster (33 MB and >900 MB respectively) for the <20 MB package. –And– the /data partition has more than 10% free (33 MB is more than 10% of 200 MB).

Surprisingly most answers don’t take this into account...

In reality, the /data partition needs a cleanup from residues from previous installs.

• Identify the common name of the problematic package (for example, com.abc.def)
• Uninstall the package (for example, pm uninstall com.abc.def)
• Check what’s left of it in data (for example, find /data -name 'com.abc.def*')
• Delete that stuff

The installer chokes on those, returning with the wrong reason. – The interesting part is: if the package gets installed on the SD card (forced or by other means) some (all?) leftovers on /data don’t hurt... which leads to the false belief that it is indeed a space problem (more space on the SD card...)!

The Stack Overflow question where I got half of this from is Solution to INSTALL_FAILED_INSUFFICIENT_STORAGE error on Android.

You can directly set the content type like below:

res.writeHead(200, {'Content-Type': 'text/plain'});

For reference go through the nodejs Docs link.

If the list you use for the spinner is an object then you can find its position like this

private int selectSpinnerValue( List<Object> ListSpinner,String myString) 
{
    int index = 0;
    for(int i = 0; i < ListSpinner.size(); i++){
      if(ListSpinner.get(i).getValueEquals().equals(myString)){
          index=i;
          break;
      }
    }
    return index;
}

using:

 int index=selectSpinnerValue(ListOfSpinner,StringEquals);
    spinner.setSelection(index,true);

// Two-dimensional GetLength example.
int[,] two = new int[5, 10];
Console.WriteLine(two.GetLength(0)); // Writes 5
Console.WriteLine(two.GetLength(1)); // Writes 10

You can override the constructor. Something like:

private class MyAsyncTask extends AsyncTask<Void, Void, Void> {

    public MyAsyncTask(boolean showLoading) {
        super();
        // do stuff
    }

    // doInBackground() et al.
}

Then, when calling the task, do something like:

new MyAsyncTask(true).execute(maybe_other_params);

Edit: this is more useful than creating member variables because it simplifies the task invocation. Compare the code above with:

MyAsyncTask task = new MyAsyncTask();
task.showLoading = false;
task.execute();

I have the answer to this problem from the BlackBerry SDK side of things: For some reason, no matter how many times I changed the options in the compiler, the actual underlying settings file did not change.

Have a look in the .settings folder of your project for a file called org.eclipse.jdt.core.prefs.

In there you can modify the settings manually:

org.eclipse.jdt.core.compiler.debug.lineNumber=generate

edit: Further to this, I have noticed that sometimes I can ignore the alert Eclipse gives, and it will still stop at the required place... curioser and curioser... I put this into the bucket of things we learn to deal with when working as dev.
