Use svcutil.exe with the /sc switch to generate the WCF contracts. This will create a code file that you can add to your project. It will contain all interfaces and data types you need to create your service. Change the output location using the /o switch, or you can find the file in the folder where you ran svcutil.exe. The default language is C# but I think (I've never tried it) you should be able to change this using /l:vb.

svcutil /sc "WSDL file path"

If your WSDL has any supporting XSD files pass those in as arguments after the WSDL.

svcutil /sc "WSDL file path" "XSD 1 file path" "XSD 2 file path" ... "XSD n file path"

Then create a new class that is your service and implement the contract interface you just created.

If you are using Laravel Framework then you can simply use this:

$allKeyList = Redis::KEYS("*");

print_r($allKeyList);

In Core PHP:

$redis = new Redis();

$redis->connect('hostname', 6379);

$allKeyList = $redis->keys('*');

print_r($allKeyList);

You need to set a name on the <select> tag like so:

<select name="select_catalog" id="select_catalog">

You can get it in php with this:

$_POST['select_catalog'];

I recently wrote on this topic, though this post it old, I thought it will be helpful to someone who wants to know how to implement BaseAdapter.notifyDataSetChanged() step by step and in a correct way.

Please follow How to correctly implement BaseAdapter.notifyDataSetChanged() in Android or the newer blog BaseAdapter.notifyDataSetChanged().

\n in c3 working correctly

using System; namespace testing2

public class Test { 
    public static void Main(string[] args) {
        Console.WriteLine("Enter your name");
        String s = Console.ReadLine();
        Console.WriteLine("Your name is " + s + "\n" + "Thank You");
    }
}

I could be wrong, but I believe since you are inheriting from foo, you have to call a base constructor. Since you explicitly defined the foo constructor to require (int, int) now you need to pass that up the chain.

public bar(int a, int b) : base(a, b)
{
     c = a * b;
}

This will initialize foo's variables first and then you can use them in bar. Also, to avoid confusion I would recommend not naming parameters the exact same as the instance variables. Try p_a or something instead, so you won't accidentally be handling the wrong variable.

With RxJS 5.5+, the catch operator is now deprecated. You should now use the catchError operator in conjunction with pipe.

RxJS v5.5.2 is the default dependency version for Angular 5.

For each RxJS Operator you import, including catchError you should now import from 'rxjs/operators' and use the pipe operator.

Example of catching error for an Http request Observable

import { Observable } from 'rxjs';
import { catchError } from 'rxjs/operators';
...

export class ExampleClass {
  constructor(private http: HttpClient) {
    this.http.request(method, url, options).pipe(
      catchError((err: HttpErrorResponse) => {
        ...
      }
    )
  }
  ...
}

Notice here that catch is replaced with catchError and the pipe operator is used to compose the operators in similar manner to what you're used to with dot-chaining.

See the rxjs documentation on pipable (previously known as lettable) operators for more info.

It's pretty easy with sympy.

import sympy

comb = sympy.binomial(n, r)

On Linux the code

setLocationRelativeTo(null)

Put my window to random location each time I launched it, in a multi display environment. And the code

setLocation((Toolkit.getDefaultToolkit().getScreenSize().width  - getSize().width) / 2, (Toolkit.getDefaultToolkit().getScreenSize().height - getSize().height) / 2);

"cut" the window in half with placing it to the exact center, which is between my two displays. I used the following method to center it:

private void setWindowPosition(JFrame window, int screen)
{        
    GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice[] allDevices = env.getScreenDevices();
    int topLeftX, topLeftY, screenX, screenY, windowPosX, windowPosY;

    if (screen < allDevices.length && screen > -1)
    {
        topLeftX = allDevices[screen].getDefaultConfiguration().getBounds().x;
        topLeftY = allDevices[screen].getDefaultConfiguration().getBounds().y;

        screenX  = allDevices[screen].getDefaultConfiguration().getBounds().width;
        screenY  = allDevices[screen].getDefaultConfiguration().getBounds().height;
    }
    else
    {
        topLeftX = allDevices[0].getDefaultConfiguration().getBounds().x;
        topLeftY = allDevices[0].getDefaultConfiguration().getBounds().y;

        screenX  = allDevices[0].getDefaultConfiguration().getBounds().width;
        screenY  = allDevices[0].getDefaultConfiguration().getBounds().height;
    }

    windowPosX = ((screenX - window.getWidth())  / 2) + topLeftX;
    windowPosY = ((screenY - window.getHeight()) / 2) + topLeftY;

    window.setLocation(windowPosX, windowPosY);
}

Makes the window appear right at the center of the first display. This is probably not the easiest solution.

Works properly on Linux, Windows and Mac.

Is this any help?

The other answers are correct, but you can, of course, do something like:

>>> str1 = "mystring"
>>> list1 = list(str1)
>>> list1[5] = 'u'
>>> str1 = ''.join(list1)
>>> print(str1)
mystrung
>>> type(str1)
<type 'str'>

if you really want to.

PLOTYY allows two different y-axes. Or you might look into LayerPlot from the File Exchange. I guess I should ask if you've considered using HOLD or just rescaling the data and using regular old plot?

OLD, not what the OP was looking for: SUBPLOT allows you to break a figure window into multiple axes. Then if you want to have only one x-axis showing, or some other customization, you can manipulate each axis independently.

Make use of the log10 function to determine the number of digits and do like below:

char * toArray(int number)
{
    int n = log10(number) + 1;
    int i;
    char *numberArray = calloc(n, sizeof(char));
    for (i = n-1; i >= 0; --i, number /= 10)
    {
        numberArray[i] = (number % 10) + '0';
    }
    return numberArray;
}

Or the other option is sprintf(yourCharArray,"%ld", intNumber);

In python notebooks I often want to filter out 'dangling' numpy.ndarray's, in particular the ones that are stored in _1, _2, etc that were never really meant to stay alive.

I use this code to get a listing of all of them and their size.

Not sure if locals() or globals() is better here.

import sys
import numpy
from humanize import naturalsize

for size, name in sorted(
    (value.nbytes, name)
    for name, value in locals().items()
    if isinstance(value, numpy.ndarray)):
  print("{:>30}: {:>8}".format(name, naturalsize(size)))

You can use NullableValueTypes (like int?) for this. The code would be like this:

private void Example(int? arg1, int? arg2)
{
    if(!arg1.HasValue)
    {
        //do something
    }
    if(!arg2.HasValue)
    {
        //do something else
    }
}

Here is my solution inspired by "Event edit" screen from iOS7 Calendar app.

One of key points of this solution is that keyboard is dismissed when user scrolls table.

Implementation:

1) Add property that will store selected textfield:

@property (strong) UITextField *currentTextField;

and BOOL variable that we will use to check if we need to hide keyboard when user scrolls table.

BOOL hideKeyboardOnScroll;

2) Handle UITextField delegate callbacks:

#pragma mark - UITextFieldDelegate

- (void) textFieldDidBeginEditing: (UITextField *) textField {
    self.currentTextField = textField;
}

- (void) textFieldDidEndEditing: (UITextField *) textField {
    self.currentTextField = nil;
}

- (BOOL) textFieldShouldReturn: (UITextField *) textField {
   [textField resignFirstResponder];

    CGPoint newContentOffset = CGPointZero;
    if (tableView.contentSize.height > tableView.frame.size.height) {
        newContentOffset.y = MIN(tableView.contentOffset.y, tableView.contentSize.height - tableView.frame.size.height);
    }
    [tableView setContentOffset: newContentOffset animated: YES];

    return YES;
}

3) Handle UIScrollViewDelegate method to check that user scroll view.

#pragma mark - UIScrollViewDelegate

- (void) scrollViewDidScroll: (UIScrollView *) scrollView {
    if (hideKeyboardOnScroll == YES) {
        [self.currentTextField resignFirstResponder];
    }
}

4) Subscribe to keyboard notifications in viewcontroller's [viewWillAppear] method and unsubscribe in [viewWillDisappear] method.

- (void) viewWillAppear: (BOOL) animated {
    [super viewWillAppear: animated];

    [ [NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyboardWillShow:)
                                                  name: UIKeyboardWillShowNotification object: nil];
    [ [NSNotificationCenter defaultCenter] addObserver: self selector: @selector(keyboardWillHide:)
                                                  name: UIKeyboardWillHideNotification object: nil];
}

- (void) viewWillDisappear: (BOOL) animated {
    [super viewWillDisappear: animated];

    [ [NSNotificationCenter defaultCenter] removeObserver: self name: UIKeyboardDidShowNotification object: nil];
    [ [NSNotificationCenter defaultCenter] removeObserver: self name: UIKeyboardWillHideNotification object: nil];    
}

5) Handle keyboard notifications:

- (void) keyboardWillShow: (NSNotification *) notification {
    CGRect keyboardFrame = [ [ [notification userInfo] objectForKey: UIKeyboardFrameBeginUserInfoKey] CGRectValue];

    // Find cell with textfield.
    CGRect textFieldFrame = [tableView convertRect: self.currentTextField.frame fromView: self.currentTextField];
    NSIndexPath *indexPath = [tableView indexPathForRowAtPoint: textFieldFrame.origin];
    UITableViewCell *cell = [tableView cellForRowAtIndexPath: indexPath];
    //

    // Shrink tableView size.
    CGRect tableViewFrame = tableView.frame;
    tableView.frame = CGRectMake(tableView.frame.origin.x, tableView.frame.origin.y, tableView.frame.size.width,
                             self.view.frame.size.height - tableView.frame.origin.y - keyboardFrame.size.height);
    //

    // Check if cell is visible in shrinked table size.
    BOOL cellIsFullyVisible = YES;
    if ( cell.frame.origin.y < tableView.contentOffset.y ||
        (cell.frame.origin.y + cell.frame.size.height) > (tableView.contentOffset.y + tableView.frame.size.height) ) {
        cellIsFullyVisible = NO;
    }
    //

    // If cell is not fully visible when scroll table to show cell;
    if (cellIsFullyVisible == NO) {
        CGPoint contentOffset = CGPointMake(tableView.contentOffset.x, CGRectGetMaxY(cell.frame) - tableView.frame.size.height);
        if (cell.frame.origin.y < tableView.contentOffset.y) {
            contentOffset.y = cell.frame.origin.y;
        }
        contentOffset.y = MAX(0, contentOffset.y);

        // For some reason [setContentOffset] is called without delay then
        // this code may not work for some cells. That why we call it with brief delay.
        dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.1 * NSEC_PER_SEC));
        dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
            [UIView animateWithDuration: 0.5 animations:^{
                [tableView setContentOffset: contentOffset animated: NO];
            } completion: ^(BOOL finished) {
                hideKeyboardOnScroll = YES;
            }];
        });
    } else {
        hideKeyboardOnScroll = YES;
    }
    //

    // Finally restore original table frame.
    tableView.frame = tableViewFrame;
    //
}

- (void) keyboardWillHide: (NSNotification *) notification {
    [super keyboardWillHide: notification];

    hideKeyboardOnScroll = NO;
}

Use count(d.ertek) or count(d.id) instead of count(d). This can be happen when you have composite primary key at your entity.

1. Don't make functions that do multiple things.
2. Don't mask then shift; shift then mask.
3. Don't mutate values unnecessarily because it's slow, cache-destroying and error-prone.
4. Don't use magic numbers.

You need to add a name attribute to your dropdown list, then you need to add a required attribute, and then you can reference the error using myForm.[input name].$error.required:

HTML:

        <form name="myForm" ng-controller="Ctrl" ng-submit="save(myForm)" novalidate>
        <input type="text" name="txtServiceName" ng-model="ServiceName" required>
<span ng-show="myForm.txtServiceName.$error.required">Enter Service Name</span>
<br/>
          <select name="service_id" class="Sitedropdown" style="width: 220px;"          
                  ng-model="ServiceID" 
                  ng-options="service.ServiceID as service.ServiceName for service in services"
                  required> 
            <option value="">Select Service</option> 
          </select> 
          <span ng-show="myForm.service_id.$error.required">Select service</span>

        </form>

    Controller:

        function Ctrl($scope) {
          $scope.services = [
            {ServiceID: 1, ServiceName: 'Service1'},
            {ServiceID: 2, ServiceName: 'Service2'},
            {ServiceID: 3, ServiceName: 'Service3'}
          ];

    $scope.save = function(myForm) {
    console.log('Selected Value: '+ myForm.service_id.$modelValue);
    alert('Data Saved! without validate');
    };
        }

Here's a working plunker.

^{To complement the existing, helpful answers; tip of the hat to QZ Support for encouraging me to post a separate answer:}

Two distinct mechanisms come into play here:

• (a) whether cut itself requires the delimiter (space, in this case) passed to the -d option to be a separate argument or whether it's acceptable to append it directly to -d.

• (b) how the shell generally parses arguments before passing them to the command being invoked.

(a) is answered by a quote from the POSIX guidelines for utilities (emphasis mine)

If the SYNOPSIS of a standard utility shows an option with a mandatory option-argument [...] a conforming application shall use separate arguments for that option and its option-argument. However, a conforming implementation shall also permit applications to specify the option and option-argument in the same argument string without intervening characters.

In other words: In this case, because -d's option-argument is mandatory, you can choose whether to specify the delimiter as:

• (s) EITHER: a separate argument
• (d) OR: as a value directly attached to -d.

Once you've chosen (s) or (d), it is the shell's string-literal parsing - (b) - that matters:

• With approach (s), all of the following forms are EQUIVALENT:

  • -d ' '
  • -d " "
  • -d \<space> # <space> used to represent an actual space for technical reasons

• With approach (d), all of the following forms are EQUIVALENT:

  • -d' '
  • -d" "
  • "-d "
  • '-d '
  • d\<space>

The equivalence is explained by the shell's string-literal processing:

All solutions above result in the exact same string (in each group) by the time cut sees them:

• (s): cut sees -d, as its own argument, followed by a separate argument that contains a space char - without quotes or \ prefix!.

• (d): cut sees -d plus a space char - without quotes or \ prefix! - as part of the same argument.

The reason the forms in the respective groups are ultimately identical is twofold, based on how the shell parses string literals:

• The shell allows literal to be specified as is through a mechanism called quoting, which can take several forms:
  • single-quoted strings: the contents inside '...' is taken literally and forms a single argument
  • double-quoted strings: the contents inside "..." also forms a single argument, but is subject to interpolation (expands variable references such as $var, command substitutions ($(...) or `...`), or arithmetic expansions ($(( ... ))).
  • \-quoting of individual characters: a \ preceding a single character causes that character to be interpreted as a literal.
• Quoting is complemented by quote removal, which means that once the shell has parsed a command line, it removes the quote characters from the arguments (enclosing '...' or "..." or \ instances) - thus, the command being invoked never sees the quote characters.

You are looking for the float.h header.

I'm probably going a million miles in the wrong direct (but i'm only young :P ). but couldn't you add the graphic to a panel and then a mouselistener to the graphic object so that when the user on the graphic your action is preformed.

Good answers above- if you're looking for something reusable here is the code. Note that you might want to check the decimal places value, and this may overflow.

public static decimal TruncateToDecimalPlace(this decimal numberToTruncate, int decimalPlaces)
{
    decimal power = (decimal)(Math.Pow(10.0, (double)decimalPlaces));

    return Math.Truncate((power * numberToTruncate)) / power;
}

There are multiple ways to achieve this. Here, I have explained the two most common approaches.

1. You can use axios interceptors to intercept any requests and add authorization headers.

// Add a request interceptor
axios.interceptors.request.use(function (config) {
    const token = store.getState().session.token;
    config.headers.Authorization =  token;

    return config;
});

2. From the documentation of axios you can see there is a mechanism available which allows you to set default header which will be sent with every request you make.

axios.defaults.headers.common['Authorization'] = AUTH_TOKEN;

So in your case:

axios.defaults.headers.common['Authorization'] = store.getState().session.token;

If you want, you can create a self-executable function which will set authorization header itself when the token is present in the store.

(function() {
     String token = store.getState().session.token;
     if (token) {
         axios.defaults.headers.common['Authorization'] = token;
     } else {
         axios.defaults.headers.common['Authorization'] = null;
         /*if setting null does not remove `Authorization` header then try     
           delete axios.defaults.headers.common['Authorization'];
         */
     }
})();

Now you no longer need to attach token manually to every request. You can place the above function in the file which is guaranteed to be executed every time (e.g: File which contains the routes).

Hope it helps :)

That’s probably everyone’s first thought. But it’s a little bit more difficult. See Chris Shiflett’s article SERVER_NAME Versus HTTP_HOST.

It seems that there is no silver bullet. Only when you force Apache to use the canonical name you will always get the right server name with SERVER_NAME.

So you either go with that or you check the host name against a white list:

$allowed_hosts = array('foo.example.com', 'bar.example.com');
if (!isset($_SERVER['HTTP_HOST']) || !in_array($_SERVER['HTTP_HOST'], $allowed_hosts)) {
    header($_SERVER['SERVER_PROTOCOL'].' 400 Bad Request');
    exit;
}

Using git rebase directly will lose the first commit. Git treats it different and can't rebase it.

There is a procedure that will preserve full history: http://kerneltrap.org/mailarchive/git/2008/10/26/3815034

I will transcribe the solution here, but credits are for Björn.

Initialize git-svn:

git svn init -s --prefix=svn/ https://svn/svn/SANDBOX/warren/test2

The --prefix gives you remote tracking branches like "svn/trunk" which is nice because you don't get ambiguous names if you call your local branch just "trunk" then. And -s is a shortcut for the standard trunk/tags/branches layout.

Fetch the initial stuff from SVN:

git svn fetch

Now look up the hash of your root commit (should show a single commit):

git rev-list --parents master | grep '^.\{40\}$'

Then get the hash of the empty trunk commit:

git rev-parse svn/trunk

Create the graft:

git replace --graft <root-commit-hash> <svn-trunk-commit-hash>

Now, "gitk" should show svn/trunk as the first commit on which your master branch is based.

Make the graft permanent:

git filter-branch -- ^svn/trunk --all

Drop the graft:

git replace -d <root-commit-hash>

gitk should still show svn/trunk in the ancestry of master.

Linearize your history on top of trunk:

git svn rebase

And now "git svn dcommit -n" should tell you that it is going to commit to trunk.

git svn dcommit

I have struggled to successfully pass arguments to the newly opened window.
Here is what I came up with :

function openWindow(path, callback /* , arg1 , arg2, ... */){
    var args = Array.prototype.slice.call(arguments, 2); // retrieve the arguments
    var w = window.open(path); // open the new window
    w.addEventListener('load', afterLoadWindow.bind(w, args), false); // listen to the new window's load event
    function afterLoadWindow(/* [arg1,arg2,...], loadEvent */){
        callback.apply(this, arguments[0]); // execute the callbacks, passing the initial arguments (arguments[1] contains the load event)
    }
}

Example call:

openWindow("/contact",function(firstname, lastname){
    this.alert("Hello "+firstname+" "+lastname);
}, "John", "Doe");

You can use the sp_MSforeachtable stored procedure like so:

USE MyDatabase
EXEC sp_MSforeachtable 'TRUNCATE TABLE ?'

Be warned that this will delete (by truncation) ALL data from all user tables. And in case you can't TRUNCATE due to foreign keys etc. you can run the same as a delete:

USE MyDatabase
EXEC sp_MSforeachtable 'DELETE FROM ?'

Abridged from: XML, Escaping

There are five predefined entities:

&lt; represents "<"
&gt; represents ">"
&amp; represents "&"
&apos; represents '
&quot; represents "

"All permitted Unicode characters may be represented with a numeric character reference." For example:

中

Most of the control characters and other Unicode ranges are specifically excluded, meaning (I think) they can't occur either escaped or direct:

Valid characters in XML

First of all check is your important change saved or not by:

$ git status

than try

$ git reset --hard

it will reset your branch to default

but if you need just undo:

$ edit (1) $ git add frotz.c filfre.c $ mailx (2) $ git reset
(3) $ git pull git://info.example.com/ nitfol

1. It is a class in org.openqa.selenium.remote.DesiredCapabilities package.
2. It gives facility to set the properties of browser. Such as to set BrowserName, Platform, Version of Browser.
3. Mostly DesiredCapabilities class used when do we used Selenium Grid.
4. We have to execute mutiple TestCases on multiple Systems with different browser with Different version and Different Operating System.

Example:

WebDriver driver;
String baseUrl , nodeUrl;
baseUrl = "https://www.facebook.com";
nodeUrl = "http://192.168.10.21:5568/wd/hub";

DesiredCapabilities capability = DesiredCapabilities.firefox();
capability.setBrowserName("firefox");
capability.setPlatform(Platform.WIN8_1);

driver = new RemoteWebDriver(new URL(nodeUrl),capability);
driver.manage().window().maximize();
driver.manage().timeouts().implicitlyWait(2, TimeUnit.MINUTES);

First, you need to open HTTPS port (443). To do that, you go to https://console.aws.amazon.com/ec2/ and click on the Security Groups link on the left, then create a new security group with also HTTPS available. Then, just update the security group of a running instance or create a new instance using that group.

After these steps, your EC2 work is finished, and it's all an application problem.

Easy with perl! If you want to get line 1, 3 and 5 from a file, say /etc/passwd:

perl -e 'while(<>){if(++$l~~[1,3,5]){print}}' < /etc/passwd

This will safely remove only if token is at end of string.

StringUtils.removeEnd(string, ".xml");

Apache StringUtils functions are null-, empty-, and no match- safe

An other approach is to use a Virtual JDBC Driver that uses a three-tier architecture: your JDBC code is sent through HTTP to a remote Servlet that filters the JDBC code (configuration & security) before passing it to the MySql JDBC Driver. The result is sent you back through HTTP. There are some free software that use this technique. Just Google "Android JDBC Driver over HTTP".

Finally, I've defeated my CiSCO EAP-FAST corporate wifi network, and all our Android devices are now able to connect to it.

The walk-around I've performed in order to gain access to this kind of networks from an Android device are easiest than you can imagine.

There's a Wifi Config Editor in the Google Play Store you can use to "activate" the secondary CISCO Protocols when you are setting up a EAP wifi connection.

Its name is Wifi Config Advanced Editor.

• First, you have to setup your wireless network manually as close as you can to your "official" corporate wifi parameters.

• Save it.

• Go to the WCE and edit the parameters of the network you have created in the previous step.

• There are 3 or 4 series of settings you should activate in order to force the Android device to use them as a way to connect (the main site I think you want to visit is Enterprise Configuration, but don't forget to check all the parameters to change them if needed.
  As a suggestion, even if you have a WPA2 EAP-FAST Cipher, try LEAP in your setup. It worked for me as a charm.

• When you finished to edit the config, go to the main Android wifi controller, and force to connect to this network.

• Do not Edit the network again with the Android wifi interface.

I have tested it on Samsung Galaxy 1 and 2, Note mobile devices, and on a Lenovo Thinkpad Tablet.

Alternatively:

public static T Cast<T>(this dynamic obj) where T:class
{
   return obj as T;
}

Most probably the issue of ImagePullBackOff is due to either the image not being present or issue with the pod YAML file.

What I will do is this

kubectl get pod -n $namespace $POD_NAME --export > pod.yaml | kubectl -f apply -

I would also see the pod.yaml to see the why the earlier pod didn't work

You have to cast the selected item to your custom class (ComboboxItem) Try this:

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
ComboBox cmb = (ComboBox)sender;
            int selectedIndex = cmb.SelectedIndex;
            string selectedText = this.comboBox1.Text;
            string selectedValue = ((ComboboxItem)cmb.SelectedItem).Value.ToString();

ComboboxItem selectedCar = (ComboboxItem)cmb.SelectedItem;
MessageBox.Show(String.Format("Index: [{0}] CarName={1}; Value={2}", selectedIndex, selectedCar.Text, selecteVal));        

}

The following CSS will right-align both the arrow and the options:

select { text-align-last: right; }_x000D_
option { direction: rtl; }

<!-- example usage -->_x000D_
Choose one: <select>_x000D_
  <option>The first option</option>_x000D_
  <option>A second, fairly long option</option>_x000D_
  <option>Last</option>_x000D_
</select>

Version used to ensure that only one update in a time. JPA provider will check the version, if the expected version already increase then someone else already update the entity so an exception will be thrown.

So updating entity value would be more secure, more optimist.

If the value changes frequent, then you might consider not to use version field. For an example "an entity that has counter field, that will increased everytime a web page accessed"

Its easy, just wrap it in a relative box like so:

<div class="relative">
 <div class="absolute">LOGO</div>
</div>

The relative box has a margin: 0 Auto; and, important, a width...

If you want to set it to any color, use below code.

id statusBarWindow = [[UIApplication sharedApplication] valueForKey:@"statusBarWindow"];
id statusBar = [statusBarWindow valueForKey:@"statusBar"];

SEL setForegroundColor_sel = NSSelectorFromString(@"setForegroundColor:");
if([statusBar respondsToSelector:setForegroundColor_sel]) {
    // iOS 7+
    [statusBar performSelector:setForegroundColor_sel withObject:YourColorHere];
                                                                 ^^^^^^^^^^^^^
}

I know I am accessing private API, but I have used this in many projects and Apple have approved it.

Just while submitting the app, send this code to Apple in Comments section and inform that you are using this code to change the status bar color.

And yes, don't forget below too.

public void Method()
{
    if(something)
    {
        //some code
        if(!something2)
        {
            return;
        }
    }
    // The code i want to go if the second if is true
}

#navigation .navigationLevel2 li
{
    color: #f00;
}

If you want to edit some complex javascript I suggest you use JsFiddle. Alternatively, for smaller pieces of javascript you can just run it through your browser URL bar, here's an example:

javascript:alert("hello world");

And, as it was already suggested both Firebug and Chrome developer tools have Javascript console, in which you can type in your javascript to execute. So do Internet Explorer 8+, Opera, Safari and potentially other modern browsers.

Autoplay only works the second time through. on android 4.1+ you have to have some kind of user event to get the first play() to work. Once that has happened then autostart works.

This is so that the user is acknowledging that they are using bandwidth.

There is another question that answers this . Autostart html5 video using android 4 browser

.msi files are windows installer files without the windows installer runtime, setup.exe can be any executable programm (probably one that installs stuff on your computer)

According to Ruby Doc instance_methods

Returns an array containing the names of the public and protected instance methods in the receiver. For a module, these are the public and protected methods; for a class, they are the instance (not singleton) methods. If the optional parameter is false, the methods of any ancestors are not included. I am taking the official documentation example.

module A
  def method1()  
    puts "method1 say hi"
  end
end
class B
  include A #mixin
  def method2()  
     puts "method2 say hi"
  end
end
class C < B #inheritance
  def method3() 
     puts "method3 say hi"
  end
end

Let's see the output.

A.instance_methods(false)
  => [:method1]

A.instance_methods
  => [:method1]
B.instance_methods
 => [:method2, :method1, :nil?, :===, ...# ] # methods inherited from parent class, most important :method1 is also visible because we mix module A in class B

B.instance_methods(false)
  => [:method2]
C.instance_methods
  => [:method3, :method2, :method1, :nil?, :===, ...#] # same as above
C.instance_methods(false)
 => [:method3]

Just clean your server (in my case I was using Tomcat):

mvn clean
mvn install

In my case I declared the animation on the wrong component by mistake.

app.component.html

  <app-order-details *ngIf="orderDetails" [@fadeInOut] [orderDetails]="orderDetails">
  </app-order-details>

The animation needs to be declared on the component where the element is used in (appComponent.ts). I was declaring the animation on OrderDetailsComponent.ts instead.

Hopefully it will help someone making the same mistake

Here is the best solution for this. (ANGULAR All Version)

Addressing solution: To set a default value for @Input variable. If no value passed to that input variable then It will take the default value.

I have provided solution for this kind of similar question. You can find the full solution from here

export class CarComponent implements OnInit {
  private _defaultCar: car = {
    // default isCar is true
    isCar: true,
    // default wheels  will be 4
    wheels: 4
  };

  @Input() newCar: car = {};

  constructor() {}

  ngOnInit(): void {

   // this will concate both the objects and the object declared later (ie.. ...this.newCar )
   // will overwrite the default value. ONLY AND ONLY IF DEFAULT VALUE IS PRESENT

    this.newCar = { ...this._defaultCar, ...this.newCar };
   //  console.log(this.newCar);
  }
}

$.getJSON() is a kind of abstraction of a regular AJAX call where you would have to tell that you want a JSON encoded response.

$.ajax({
  url: url,
  dataType: 'json',
  data: data,
  success: callback
});

You can handle errors in two ways: generically (by configuring your AJAX calls before actually calling them) or specifically (with method chain).

'generic' would be something like:

$.ajaxSetup({
      "error":function() { alert("error");  }
});

And the 'specific' way:

$.getJSON("example.json", function() {
  alert("success");
})
.done(function() { alert("second success"); })
.fail(function() { alert("error"); })
.always(function() { alert("complete"); });

As a good practice you can use an Ant Script (Eclipse comes with it) to generate your JAR file. Inside this JAR you can have all dependent libs.

You can even set the MANIFEST's Class-path header to point to files in your filesystem, it's not a good practice though.

Ant build.xml script example:

All of the following examples use

var str = "Hello, playground"

startIndex and endIndex

• startIndex is the index of the first character
• endIndex is the index after the last character.

Example

// character
str[str.startIndex] // H
str[str.endIndex]   // error: after last character

// range
let range = str.startIndex..<str.endIndex
str[range]  // "Hello, playground"

With Swift 4's one-sided ranges, the range can be simplified to one of the following forms.

let range = str.startIndex...
let range = ..<str.endIndex

I will use the full form in the follow examples for the sake of clarity, but for the sake of readability, you will probably want to use the one-sided ranges in your code.

after

As in: index(after: String.Index)

• after refers to the index of the character directly after the given index.

Examples

// character
let index = str.index(after: str.startIndex)
str[index]  // "e"

// range
let range = str.index(after: str.startIndex)..<str.endIndex
str[range]  // "ello, playground"

before

As in: index(before: String.Index)

• before refers to the index of the character directly before the given index.

Examples

// character
let index = str.index(before: str.endIndex)
str[index]  // d

// range
let range = str.startIndex..<str.index(before: str.endIndex)
str[range]  // Hello, playgroun

offsetBy

As in: index(String.Index, offsetBy: String.IndexDistance)

• The offsetBy value can be positive or negative and starts from the given index. Although it is of the type String.IndexDistance, you can give it an Int.

Examples

// character
let index = str.index(str.startIndex, offsetBy: 7)
str[index]  // p

// range
let start = str.index(str.startIndex, offsetBy: 7)
let end = str.index(str.endIndex, offsetBy: -6)
let range = start..<end
str[range]  // play

limitedBy

As in: index(String.Index, offsetBy: String.IndexDistance, limitedBy: String.Index)

• The limitedBy is useful for making sure that the offset does not cause the index to go out of bounds. It is a bounding index. Since it is possible for the offset to exceed the limit, this method returns an Optional. It returns nil if the index is out of bounds.

Example

// character
if let index = str.index(str.startIndex, offsetBy: 7, limitedBy: str.endIndex) {
    str[index]  // p
}

If the offset had been 77 instead of 7, then the if statement would have been skipped.

Why is String.Index needed?

It would be much easier to use an Int index for Strings. The reason that you have to create a new String.Index for every String is that Characters in Swift are not all the same length under the hood. A single Swift Character might be composed of one, two, or even more Unicode code points. Thus each unique String must calculate the indexes of its Characters.

It is possibly to hide this complexity behind an Int index extension, but I am reluctant to do so. It is good to be reminded of what is actually happening.

use ProgressDialog.

ProgressDialog dialog=new ProgressDialog(context);
dialog.setMessage("message");
dialog.setCancelable(false);
dialog.setInverseBackgroundForced(false);
dialog.show();

hide it whenever your UI is ready with data. call :

dialog.hide();

Short answer:
_{Remove (from list results)}

results.RemoveAll(r => r.ID == 2); will remove the item with ID 2 in results (in place).

_{Filter (without removing from original list results):}

var filtered = result.Where(f => f.ID != 2); returns all items except the one with ID 2

Detailed answer:

I think .RemoveAll() is very flexible, because you can have a list of item IDs which you want to remove - please regard the following example.

If you have:

class myClass {
    public int ID; public string FirstName; public string LastName;
}

and assigned some values to results as follows:

var results = new List<myClass> {
    new myClass { ID=1, FirstName="Bill", LastName="Smith" },   // results[0]
    new myClass { ID=2, FirstName="John", LastName="Wilson" },  // results[1]
    new myClass { ID=3, FirstName="Doug", LastName="Berg" },    // results[2]
    new myClass { ID=4, FirstName="Bill", LastName="Wilson" }   // results[3]
};

Then you can define a list of IDs to remove:

var removeList = new List<int>() { 2, 3 };

And simply use this to remove them:

results.RemoveAll(r => removeList.Any(a => a==r.ID));

It will remove the items 2 and 3 and keep the items 1 and 4 - as specified by the removeList. Note that this happens in place, so there is no additional assigment required.

Of course, you can also use it on single items like:

results.RemoveAll(r => r.ID==4);

where it will remove Bill with ID 4 in our example.

A last thing to mention is that lists have an indexer, that is, they can also be accessed like a dynamic array, i.e. results[3] will give you the 4th element in the results list (because the first element has the index 0, the 2nd has index 1 etc).

So if you want to remove all entries where the first name is the same as in the 4th element of the results list, you can simply do it this way:

results.RemoveAll(r => results[3].FirstName == r.FirstName);

Note that afterwards, only John and Doug will remain in the list, Bill is removed (the first and last element in the example). Important is that the list will shrink automatically, so it has only 2 elements left - and hence the largest allowed index after executing RemoveAll in this example is 1
(which is results.Count() - 1).

Some Trivia: You can use this knowledge and create a local function

void myRemove()  { var last = results.Count() - 1; 
                   results.RemoveAll(r => results[last].FirstName == r.FirstName); }

What do you think will happen, if you call this function twice? Like

myRemove(); myRemove(); 

The first call will remove Bill at the first and last position, the second call will remove Doug and only John Wilson remains in the list.

DotNetFiddle: Run the demo

Note: Since C# Version 8, you can as well write results[^1] instead of var last = results.Count() - 1; and results[last]:

void myRemove() { results.RemoveAll(r => results[^1].FirstName == r.FirstName); }

So you would not need the local variable last anymore (see indices and ranges. For a list of all the new features in C#, look here).

Answer by Caleb Spare posted in gonuts mailing list.

[...] It's not actually needed very often and [...] using os.Stat is easy enough for the cases where it is required.

[...] For instance: if you are going to open the file, there's no reason to check whether it exists first. The file could disappear in between checking and opening, and anyway you'll need to check the os.Open error regardless. So you simply call os.IsNotExist(err) after you try to open the file, and deal with its non-existence there (if that requires special handling).

[...] You don't need to check for the paths existing at all (and you shouldn't).

• os.MkdirAll works whether or not the paths already exist. (Also you need to check the error from that call.)

• Instead of using os.Create, you should use os.OpenFile(path, os.O_RDWR|os.O_CREATE|os.O_EXCL, 0666) . That way you'll get an error if the file already exists. Also this doesn't have a race condition with something else making the file, unlike your version which checks for existence beforehand.

i also recommend thinking this thru and then choosing to store images in your file system rather than the DB .. see here: Storing Images in DB - Yea or Nay?

There is no Pair in the standard framework, but the Apache Commons Lang, which comes quite close to “standard”, has a Pair.

Use string like LocalDate.parse(((String) data.get("d_iso8601")),DateTimeFormatter.ISO_DATE)

You can be explicit about the joins:

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

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

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

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

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

If you have Cygwin installed (which I strongly recommend for a variety of reasons), you could use the 'file' utility on the DLL

file <filename>

which would give an output like this:

icuuc36.dll: MS-DOS executable PE  for MS Windows (DLL) (GUI) Intel 80386 32-bit

You can also use the $inject service to get whatever service you like. I find that useful if I don't know the service name ahead of time but know the service interface. For example a directive that will plug a table into an ngResource end point or a generic delete-record button which interacts with any api end point. You don't want to re-implement the table directive for every controller or data-source.

template.html

<div my-directive api-service='ServiceName'></div>

my-directive.directive.coffee

angular.module 'my.module'
  .factory 'myDirective', ($injector) ->
    directive = 
      restrict: 'A'
      link: (scope, element, attributes) ->
        scope.apiService = $injector.get(attributes.apiService)

now your 'anonymous' service is fully available. If it is ngResource for example you can then use the standard ngResource interface to get your data

For example:

scope.apiService.query((response) ->
  scope.data = response
, (errorResponse) ->
  console.log "ERROR fetching data for service: #{attributes.apiService}"
  console.log errorResponse.data
)

I have found this technique to be very useful when making elements that interact with API endpoints especially.

This works too and you dont have to use join or anything:

DROP VIEW IF EXISTS yourview;

CREATE VIEW yourview AS
    SELECT table1.column1, 
    table2.column2
FROM 
table1, table2 
WHERE table1.column1 = table2.column1;

I believe Twitter Bootstrap has a class called clearfix that you can use to clear the floating.

<ul class="nav nav-tabs span2 clearfix">

When we want to take Integer as inputs
For just 3 inputs as in your case:

import java.util.Scanner;
Scanner scan = new Scanner(System.in);
int a,b,c;
a = scan.nextInt();
b = scan.nextInt();
c = scan.nextInt();

For more number of inputs we can use a loop:

import java.util.Scanner;
Scanner scan = new Scanner(System.in);
int a[] = new int[n]; //where n is the number of inputs
for(int i=0;i<n;i++){
    a[i] = scan.nextInt();    
}

y <- mean(x, na.rm=TRUE)

sd(y) for standard deviation var(y) for variance.

Both derivations use n-1 in the denominator so they are based on sample data.

ERROR: Linux / Centos:

Job for jenkins.service failed because the control process exited with error code. See "systemctl status jenkins.service" and "journalctl -xe" for details.

Solution:

• Edit the Jenkins init file by doing

  sudo vi /etc/init.d/jenkins
  

• Add your own Java path, for example:

  /opt/oracle/product/java/jdk1.8.0_45/bin/java
  

• Restart the service:

  sudo service jenkins start
  sudo service jenkins status
  sudo service jenkins stop
  

Yes:

float[] values = {0.1f, 0.2f, 0.3f};

This syntax is only permissible in an initializer. You cannot use it in an assignment, where the following is the best you can do:

values = new float[3];

or

values = new float[] {0.1f, 0.2f, 0.3f};

Trying to find a reference in the language spec for this, but it's as unreadable as ever. Anyone else find one?

I also had same issue on my mac. I was running 5.3.0 version. I removed that version and installed 7.2.1 version. After this it is working in my case.

declare @MyNumber float 
set @MyNumber = 123.45 
select 'My number is ' + CAST(@MyNumber as nvarchar(max))

The probably only way which is marginally faster than

d = [[] for x in xrange(n)]

is

from itertools import repeat
d = [[] for i in repeat(None, n)]

It does not have to create a new int object in every iteration and is about 15 % faster on my machine.

Edit: Using NumPy, you can avoid the Python loop using

d = numpy.empty((n, 0)).tolist()

but this is actually 2.5 times slower than the list comprehension.

You need to install tkinter for python3.

On Fedora pip3 install tkinter --user returns Could not find a version that satisfies the requirement... so I have to command: dnf install python3-tkinter. This have solved my problem

General ternary syntax:

value_true if <test> else value_false

Another way can be:

[value_false, value_true][<test>]

e.g:

count = [0,N+1][count==N]

This evaluates both branches before choosing one. To only evaluate the chosen branch:

[lambda: value_false, lambda: value_true][<test>]()

e.g.:

count = [lambda:0, lambda:N+1][count==N]()

That header doesn't exist in standard C++. It was part of some pre-1990s compilers, but it is certainly not part of C++.

Use #include <iostream> instead. And all the library classes are in the std:: namespace, for ex­am­ple std::cout.

Also, throw away any book or notes that mention the thing you said.

Adding "/usr/bin/git" >> Path to Git executable, didn't work for me. Then I deleted the contents of $JENKINS_HOME/fingerprints and restarted Jenkins. The problem goes away.

I have been using this function for a while with no problems. You just need to provide the number columns there are in the csv file, and it will take the header names from the first row and create the table for you:

create or replace function data.load_csv_file
    (
        target_table  text, -- name of the table that will be created
        csv_file_path text,
        col_count     integer
    )

    returns void

as $$

declare
    iter      integer; -- dummy integer to iterate columns with
    col       text; -- to keep column names in each iteration
    col_first text; -- first column name, e.g., top left corner on a csv file or spreadsheet

begin
    set schema 'data';

    create table temp_table ();

    -- add just enough number of columns
    for iter in 1..col_count
    loop
        execute format ('alter table temp_table add column col_%s text;', iter);
    end loop;

    -- copy the data from csv file
    execute format ('copy temp_table from %L with delimiter '','' quote ''"'' csv ', csv_file_path);

    iter := 1;
    col_first := (select col_1
                  from temp_table
                  limit 1);

    -- update the column names based on the first row which has the column names
    for col in execute format ('select unnest(string_to_array(trim(temp_table::text, ''()''), '','')) from temp_table where col_1 = %L', col_first)
    loop
        execute format ('alter table temp_table rename column col_%s to %s', iter, col);
        iter := iter + 1;
    end loop;

    -- delete the columns row // using quote_ident or %I does not work here!?
    execute format ('delete from temp_table where %s = %L', col_first, col_first);

When we try to run python file with path from terminal.

import sys
#For file name
file_name=sys.argv[0]
#For first argument
dir= sys.argv[1]
print("File Name: {}, argument dir: {}".format(file_name, dir)

Save the file (test.py).

Runing system.

Open terminal and go the that dir where is save file. then write

python test.py "/home/saiful/Desktop/bird.jpg"

Hit enter

Output:

File Name: test, Argument dir: /home/saiful/Desktop/bird.jpg

You can always do

git clone git://repo.org/fossproject.git && rm -rf fossproject/.git

private String getApplicationName(Context context, String data, int flag) {

   final PackageManager pckManager = context.getPackageManager();
   ApplicationInfo applicationInformation;
   try {
       applicationInformation = pckManager.getApplicationInfo(data, flag);
   } catch (PackageManager.NameNotFoundException e) {
       applicationInformation = null;
   }
   final String applicationName = (String) (applicationInformation != null ? pckManager.getApplicationLabel(applicationInformation) : "(unknown)");
   return applicationName;

}

This can be done using the numeric_limits in C++:

http://www.cplusplus.com/reference/limits/numeric_limits/

These are the methods you probably want to look at:

infinity()  T   Representation of positive infinity, if available.
quiet_NaN() T   Representation of quiet (non-signaling) "Not-a-Number", if available.
signaling_NaN() T   Representation of signaling "Not-a-Number", if available.

Please use datatable if you want to get result from json object. Datatable also works in the same manner of converting the json result into table format with the facility of searchable and sortable columns automatically.

Try

curl -G ...

instead of

curl -X GET ...

Normally you don't need this option. All sorts of GET, HEAD, POST and PUT requests are rather invoked by using dedicated command line options.

This option only changes the actual word used in the HTTP request, it does not alter the way curl behaves. So for example if you want to make a proper HEAD request, using -X HEAD will not suffice. You need to use the -I, --head option.

plot(t) is in this case the same as

plot(t[[1]], t[[2]])

As the error message says, x and y differ in length and that is because you plot a list with length 4 against 1:

> length(t)
[1] 4
> length(1)
[1] 1

In your second example you plot a list with elements named x and y, both vectors of length 2, so plot plots these two vectors.

Edit:

If you want to plot lines use

plot(t, type="l")

I wrapped my line that was crashing in a try-catch block, printed out the exception, and breaked immediately after it was printed. The exception information shown had a stack trace which pointed me to the file and line of code causing the fault to occur.

System.TypeInitializationException: The type initializer for 'Blah.blah.blah' threw an exception. 
---> System.NullReferenceException: Object reference not set to an instance of an object.
   at Some.Faulty.Software..cctor() in C:\Projects\My.Faulty.File.cs:line 56
   --- End of inner exception stack trace ---
   at Blah.blah.blah(Blah.blah.blah)
   at TestApplication.Program.Main(String[] args) 
   in C:\Projects\Blah.blah.blah\Program.cs:line 29 Exception caught.

To add my 2 cents, the exception can occur even if you call your code through System.Windows.Threading.Dispatcher.CurrentDispatcher.Invoke().
The point is that you have to call Invoke() of the Dispatcher of the control that you're trying to access, which in some cases may not be the same as System.Windows.Threading.Dispatcher.CurrentDispatcher. So instead you should use YourControl.Dispatcher.Invoke() to be safe. I was banging my head for a couple of hours before I realized this.

Update

For future readers, it looks like this has changed in the newer versions of .NET (4.0 and above). Now you no longer have to worry about the correct dispatcher when updating UI-backing properties in your VM. WPF engine will marshal cross-thread calls on the correct UI thread. See more details here. Thanks to @aaronburro for the info and link. You may also want to read our conversation below in comments.

I solved this a different way, this may be easier for some.

I did it this way because I tried starting in safe mode but cannot connect with the error: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

What I did was to connect normally as root:

$ sudo mysql -u root

Then I created a new super user:

mysql> grant all privileges on *.* to 'myuser'@'%' identified by 'mypassword' with grant option;
mysql> quit

Then log in as myuser

$ mysql -u myuser -p -h localhost

Trying to change the password gave me no errors but did nothing for me so I dropped and re-created the root user

mysql> drop user 'root'@'localhost;
mysql> mysql> grant all privileges on *.* to 'root'@'localhost' identified by 'mypassword' with grant option;

The root user is now working with the new password

Swapping the values from 1st position to till the end of the list, this code loops for ( n*n-1)/2 times. Each time it pushes the greater value to the greater index starting from Zero index.

list2 = [40,-5,10,2,0,-4,-10]
for l in range(len(list2)):
    for k in range(l+1,len(list2)):
        if list2[k] < list2[l]:
            list2[k] , list2[l] = list2[l], list2[k]
print(list2)

Simple you can try this

a=list(zip(portfolio, index))

You can do that in PL/SQL Developer v10.
1. Click on Table that you want to generate script for.
2. Click Export data.
3. Check if table is selected that you want to export data for.
4. Click on SQL inserts tab.
5. Add where clause if you don't need the whole table.
6. Select file where you will find your SQL script.
7. Click export.

To detect both positive and negative peaks, PeakDetect is helpful.

from peakdetect import peakdetect

peaks = peakdetect(data, lookahead=20) 
# Lookahead is the distance to look ahead from a peak to determine if it is the actual peak. 
# Change lookahead as necessary 
higherPeaks = np.array(peaks[0])
lowerPeaks = np.array(peaks[1])
plt.plot(data)
plt.plot(higherPeaks[:,0], higherPeaks[:,1], 'ro')
plt.plot(lowerPeaks[:,0], lowerPeaks[:,1], 'ko')

A SHA1 hash is 40 chars long!

I just want to add to what's been said so far, it may save a lot of headache, you don't need to wait 24 hour to see if it works, yes the total overview take 24 hour, but in Reporting tab, there is a link on left side to Real-Time result and it will show if anyone currently visiting your site, also I didn't have to set 'cookieDomain': 'none' for it to work on localhost, my setting is on 'auto' and it works just fine (I'm using MVC 5), on top of that I've added the script at the end of head tag as google stated in this page:

Paste your snippet (unaltered, in its entirety) into every web page you want to track. Paste it immediately before the closing </head> tag.

here is more info on how to check to see if analytics works properly.

This is a guess :)

Is it because the ID is a string? What happens if you change it to int?

I mean:

 public int Id { get; set; }

It sounds as if the only problem here is that the default editor that is launched is vi or vim, with which you're not familiar. (As quick tip, to exit that editor without saving changes, hit Esc a few times and then type :, q, ! and Enter.)

There are several ways to set up your default editor, and you haven't indicated which operating system you're using, so it's difficult to recommend one in particular. I'd suggest using:

 git config --global core.editor "name-of-your-editor"

... which sets a global git preference for a particular editor. Alternatively you can set the $EDITOR environment variable.

To append to an array, just use the += operator.

$Target += $TargetObject

Also, you need to declare $Target = @() before your loop because otherwise, it will empty the array every loop.

    $('#checkbox').click(function(){
        $('#submit').attr('disabled', !$(this).attr('checked'));
    });

If you look deeper into the other uses of size you can see that you can actually get a vector of the size of each dimension. This link shows you the documentation:

www.mathworks.com/access/helpdesk/help/techdoc/ref/size.html

After getting the size vector, iterate over that vector. Something like this (pardon my syntax since I have not used Matlab since college):

d = size(m);
dims = ndims(m);
for dimNumber = 1:dims
   for i = 1:d[dimNumber]
      ...

Make this into actual Matlab-legal syntax, and I think it would do what you want.

Also, you should be able to do Linear Indexing as described here.

It should be text-align, not align

https://developer.mozilla.org/en/CSS/text-align

The "ternary expression" x ? y : z can only be used for conditional assignment. That is, you could do something like:

String mood = inProfit() ? "happy" : "sad";

because the ternary expression is returning something (of type String in this example).

It's not really meant to be used as a short, in-line if-else. In particular, you can't use it if the individual parts don't return a value, or return values of incompatible types. (So while you could do this if both method happened to return the same value, you shouldn't invoke it for the side-effect purposes only).

So the proper way to do this would just be with an if-else block:

if (jXPanel6.isVisible()) {
    jXPanel6.setVisible(true);
}
else {
    jXPanel6.setVisible(false);
}

which of course can be shortened to

jXPanel6.setVisible(jXPanel6.isVisible());

Both of those latter expressions are, for me, more readable in that they more clearly communicate what it is you're trying to do. (And by the way, did you get your conditions the wrong way round? It looks like this is a no-op anyway, rather than a toggle).

Don't mix up low character count with readability. The key point is what is most easily understood; and mildly misusing language features is a definite way to confuse readers, or at least make them do a mental double-take.

InnerText property html-encodes the content, turning <p> to <p>, etc. If you want to insert HTML tags you need to use InnerHTML.

To replace all spaces :

UPDATE `table` SET `col_name` = REPLACE(`col_name`, ' ', '')

To remove all tabs characters :

UPDATE `table` SET `col_name` = REPLACE(`col_name`, '\t', '' )

To remove all new line characters :

UPDATE `table` SET `col_name` = REPLACE(`col_name`, '\n', '')

http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_replace

To remove first and last space(s) of column :

UPDATE `table` SET `col_name` = TRIM(`col_name`)

http://dev.mysql.com/doc/refman/5.0/en/string-functions.html#function_trim

This is a lexicographical ordering. It just puts things in dictionary order.

Installing webpack with -g option installs webpack in a folder in

C:\Users\<.profileusername.>\AppData\Roaming\npm\node_modules

same with webpack-cli and webpack-dev-server

Outside the global node_modules a link is created for webpack to be run from commandline

C:\Users\<.profileusername.>\AppData\Roaming\npm

to make this work locally, I did the following

1. renamed the webpack folder in global node_modules to _old
2. installed webpack locally within project
3. edited the command link webpack.cmd and pointed the webpack.js to look into my local node_modules folder within my application

Problem with this approach is you'd have to maintain links for each project you have. Theres no other way since you are using the command line editor to run webpack command when installing with a -g option.

So if you had proj1, proj2 and proj3 all with their local node_modules and local webpack installed( not using -g when installing), then you'd have to create non-generic link names instead of just webpack.

example here would be to create webpack_proj1.cmd, webpack_proj2.cmd and webpack_proj3.cmd and in each cmd follow point 2 and 3 above

PS: dont forget to update your package.json with these changes or else you'll get errors as it won't find webpack command

1. In your for loop, you're iterating through the elements of a list a. But in the body of the loop, you're using those items to index that list, when you actually want indexes.
   Imagine if the list a would contain 5 items, a number 100 would be among them and the for loop would reach it. You will essentially attempt to retrieve the 100th element of the list a, which obviously is not there. This will give you an IndexError.

We can fix this issue by iterating over a range of indexes instead:

for i in range(len(a))

and access the a's items like that: a[i]. This won't give any errors.

2. In the loop's body, you're indexing not only a[i], but also a[i+1]. This is also a place for a potential error. If your list contains 5 items and you're iterating over it like I've shown in the point 1, you'll get an IndexError. Why? Because range(5) is essentially 0 1 2 3 4, so when the loop reaches 4, you will attempt to get the a[5] item. Since indexing in Python starts with 0 and your list contains 5 items, the last item would have an index 4, so getting the a[5] would mean getting the sixth element which does not exist.

To fix that, you should subtract 1 from len(a) in order to get a range sequence 0 1 2 3. Since you're using an index i+1, you'll still get the last element, but this way you will avoid the error.

3. There are many different ways to accomplish what you're trying to do here. Some of them are quite elegant and more "pythonic", like list comprehensions:

b = [a[i] + a[i+1] for i in range(len(a) - 1)]

This does the job in only one line.

SELECT Call.ID, Call.date, Call.phone_number 
FROM Call 
LEFT OUTER JOIN Phone_Book 
  ON (Call.phone_number=Phone_book.phone_number) 
  WHERE Phone_book.phone_number IS NULL

Should remove the subquery, allowing the query optimiser to work its magic.

Also, avoid "SELECT *" because it can break your code if someone alters the underlying tables or views (and it's inefficient).

Another alternative: you can check if an item is in a list with if item in list:, but this is order O(n). If you are dealing with big lists of items and all you need to know is whether something is a member of your list, you can convert the list to a set first and take advantage of constant time set lookup:

my_set = set(my_list)
if item in my_set:  # much faster on average than using a list
    # do something

Not going to be the correct solution in every case, but for some cases this might give you better performance.

Note that creating the set with set(my_list) is also O(n), so if you only need to do this once then it isn't any faster to do it this way. If you need to repeatedly check membership though, then this will be O(1) for every lookup after that initial set creation.

I prefer John T's solution, but if you want to go all code-golfy, your statement logically reduces to this:

//if key is down, toggle the boolean, else leave it alone.
flipVal = ((wParam==VK_F11) && !flipVal) || (!(wParam==VK_F11) && flipVal);
if(wParam==VK_F11) Break;

//if key is down, toggle the boolean, else leave it alone.
otherVal = ((wParam==VK_F12) && !otherVal) || (!(wParam==VK_F12) && otherVal);
if(wParam==VK_F12) Break;

Just additional note:

when you creating a new project from start.spring.io make sure you select your JDK version theirs by default is set to JDK 11, later it will cause the above issue.

In my case, the phone screen size is unknown, and here is what I did.

HTML

<div class="loadingImg"></div>

CSS

.loadingImg{
    position: fixed;
    top: 0px;
    left: 0px;
    z-index: 9999999;
    border: 0;
    background: url('../images/loading.gif') no-repeat center;
    background-size: 50px 50px;
    display: block;
    margin: 0 auto;
    -webkit-border-radius: 50px;
    border-radius: 50px;
}

JavaScript (before you need to show this DIV)

$(".loadingImg").css("height",$(document).height());
$(".loadingImg").css("width",$(document).width());
$(".loadingImg").show();

I just wanted to add my opinion about this.

I think we can just use like this:

var haystack = 'hello world';
var needle = 'he';

if (haystack.indexOf(needle) == 0) {
  // Code if string starts with this substring
}

Hope it helps.

Add the following on your css file

.popover{
         width:auto !important; 
         max-width:445px !important; 
         min-width:200px !important;
       }

Try Adminer. The whole application is in one PHP file, which means that the deployment is as easy as it can get. It's more powerful than phpMyAdmin; it can edit views, procedures, triggers, etc.

Adminer is also a universal tool, it can connect to MySQL, PostgreSQL, SQLite, MS SQL, Oracle, SimpleDB, Elasticsearch and MongoDB.

You should definitely give it a try.

You can install on Ubuntu with sudo apt-get install adminer or you can also download the latest version from adminer.org

I would imagine Google grabs some data server-side - remember, when a page loads into your browser that has Google Analytics code within it, your browser makes a request to Google's servers; Google can obtain data in that way as well as through the JavaScript embedded in the page.

I liked the (C#) code in the following which sets the registry settings for your app. Not sure if it will cut it after installation though if permissions are required. For me it solved an issue with WebSocket not being available inside a WebBrowser control in WPF.

Worksheets("Sheet2").Range("P2").Value = Worksheets("Sheet1").Range("L10") 

This is a CopynPaste - Method

     MsgBox "No matching date was found."
     Exit Sub

   Wend

   Exit Sub

Err_Execute:

And there might be some methods doing that in Excel.

Adding on to make it full circle, to retrieve the path of every folder, use a combination of Albert's answer as well as Gordans. That should be pretty useful.

for i in $(ls -d /pathto/parent/folder/*/); do echo ${i%%/}; done

Output:

/pathto/parent/folder/childfolder1/
/pathto/parent/folder/childfolder2/
/pathto/parent/folder/childfolder3/
/pathto/parent/folder/childfolder4/
/pathto/parent/folder/childfolder5/
/pathto/parent/folder/childfolder6/
/pathto/parent/folder/childfolder7/
/pathto/parent/folder/childfolder8/

FYI: You could get a similar behavior to what you want by creating extension methods for the interface. The extension method would be a shared, non overridable static behavior. However, unfortunately, this static method would not be part of the contract.

if you get "unexpected Character" error you should check if there is a BOM (Byte Order Marker saved into your utf-8 json. You can either remove the first character or save if without BOM.

Tracking individual changed items in a list

If you want to watch all items in a list and know which item in the list changed, you can set up custom watchers on every item separately, like so:

var vm = new Vue({
  data: {
    list: [
      {name: 'obj1 to watch'},
      {name: 'obj2 to watch'},
    ],
  },
  methods: {
    handleChange (newVal, oldVal) {
      // Handle changes here!
      // NOTE: For mutated objects, newVal and oldVal will be identical.
      console.log(newVal);
    },
  },
  created () {
    this.list.forEach((val) => {
      this.$watch(() => val, this.handleChange, {deep: true});
    });
  },
});

If your list isn't populated straight away (like in the original question), you can move the logic out of created to wherever needed, e.g. inside the .then() block.

Watching a changing list

If your list itself updates to have new or removed items, I've developed a useful pattern that "shallow" watches the list itself, and dynamically watches/unwatches items as the list changes:

// NOTE: This example uses Lodash (_.differenceBy and _.pull) to compare lists
//       and remove list items. The same result could be achieved with lots of
//       list.indexOf(...) if you need to avoid external libraries.

var vm = new Vue({
  data: {
    list: [
      {name: 'obj1 to watch'},
      {name: 'obj2 to watch'},
    ],
    watchTracker: [],
  },
  methods: {
    handleChange (newVal, oldVal) {
      // Handle changes here!
      console.log(newVal);
    },
    updateWatchers () {
      // Helper function for comparing list items to the "watchTracker".
      const getItem = (val) => val.item || val;

      // Items that aren't already watched: watch and add to watched list.
      _.differenceBy(this.list, this.watchTracker, getItem).forEach((item) => {
        const unwatch = this.$watch(() => item, this.handleChange, {deep: true});
        this.watchTracker.push({ item: item, unwatch: unwatch });
        // Uncomment below if adding a new item to the list should count as a "change".
        // this.handleChange(item);
      });

      // Items that no longer exist: unwatch and remove from the watched list.
      _.differenceBy(this.watchTracker, this.list, getItem).forEach((watchObj) => {
        watchObj.unwatch();
        _.pull(this.watchTracker, watchObj);
        // Optionally add any further cleanup in here for when items are removed.
      });
    },
  },
  watch: {
    list () {
      return this.updateWatchers();
    },
  },
  created () {
    return this.updateWatchers();
  },
});

The documentation for required() states:

To force a user to select an option from a select box, provide an empty options like <option value="">Choose...</option>

By having value="none" in your <option> tag, you are preventing the validation call from ever being made. You can also remove your custom validation rule, simplifying your code. Here's a jsFiddle showing it in action:

http://jsfiddle.net/Kn3v5/

If you can't change the value attribute to the empty string, I don't know what to tell you...I couldn't find any way to get it to validate otherwise.

Status 422 (RFC 4918, Section 11.2) comes to mind:

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

To have text-align:center work you need to add that style to the #siteInfo div or wrap the input in a paragraph and add text-align:center to the paragraph.

Try:

mmatrix = np.zeros((nrows, ncols))

Since the shape parameter has to be an int or sequence of ints

http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html

Otherwise you are passing ncols to np.zeros as the dtype.

Your [hidden] will work but you need to check the css:

<input class="txt" type="password" [(ngModel)]="input_pw" [hidden]="isHidden" />

And the css:

[hidden] {
  display: none !important;
}

That should work as you want.

In my case, I wanted to move a submodule from one directory into a subdirectory, e.g. "AFNetworking" -> "ext/AFNetworking". These are the steps I followed:

1. Edit .gitmodules changing submodule name and path to be "ext/AFNetworking"
2. Move submodule's git directory from ".git/modules/AFNetworking" to ".git/modules/ext/AFNetworking"
3. Move library from "AFNetworking" to "ext/AFNetworking"
4. Edit ".git/modules/ext/AFNetworking/config" and fix the [core] worktree line. Mine changed from ../../../AFNetworking to ../../../../ext/AFNetworking
5. Edit "ext/AFNetworking/.git" and fix gitdir. Mine changed from ../.git/modules/AFNetworking to ../../git/modules/ext/AFNetworking
6. git add .gitmodules
7. git rm --cached AFNetworking
8. git submodule add -f <url> ext/AFNetworking

Finally, I saw in the git status:

matt$ git status
# On branch ios-master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   modified:   .gitmodules
#   renamed:    AFNetworking -> ext/AFNetworking

Et voila. The above example doesn't change the directory depth, which makes a big difference to the complexity of the task, and doesn't change the name of the submodule (which may not really be necessary, but I did it to be consistent with what would happen if I added a new module at that path.)

Right click on the project, go to "Run as", select "Run configurations" and create a run configuration.

Now there is the pandas_profiling package, which is a more complete alternative to df.describe().

If your pandas dataframe is df, the below will return a complete analysis including some warnings about missing values, skewness, etc. It presents histograms and correlation plots as well.

import pandas_profiling
pandas_profiling.ProfileReport(df)

See the example notebook detailing the usage.

Anyone here looking for Knockout JS integration.

Given the following HTML (Standard Bootstrap dropdown button):

<div class="dropdown">
    <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
        Select an item               
        <span class="caret"></span>
    </button>
    <ul class="dropdown-menu" role="menu">
        <li>
            <a href="javascript:;" data-bind="click: clickTest">Click 1</a>
        </li>
        <li>
            <a href="javascript:;" data-bind="click: clickTest">Click 2</a>
        </li>
        <li>
            <a href="javascript:;" data-bind="click: clickTest">Click 3</a>
        </li>
    </ul>
</div>

Use the following JS:

var viewModel = function(){
    var self = this;

    self.clickTest = function(){
        alert("I've been clicked!");
    }  
};

For those looking to generate dropdown options based on knockout observable array, the code would look something like:

var viewModel = function(){
    var self = this;

    self.dropdownOptions = ko.observableArray([
        { id: 1, label: "Click 1" },
        { id: 2, label: "Click 2" },
        { id: 3, label: "Click 3" }
    ])

    self.clickTest = function(item){
        alert("Item with id:" + item.id + " was clicked!");

If you using gnome, and turned off the proxy at the network level, you also need to make sure you don't have proxy enabled in your terminal

? gconftool-2 -a /system/http_proxy  
 host = http://localhost/
 port = 2000
 use_http_proxy = false
 use_authentication = false
 authentication_password = 
 authentication_user = 
 ignore_hosts = [localhost,127.0.0.0/8]

You can drop it with

gconftool-2 -t string -s /system/http_proxy/host ""
gconftool-2 -u /system/http_proxy/port
gconftool-2 -u /system/http_proxy/host
unset http_proxy

Consider TCP over ATM. ATM uses 48 byte frames, but clearly TCP packets can be bigger than that. A frame is the chunk of data sent as a unit over the data link (Ethernet, ATM). A packet is the chunk of data sent as a unit over the layer above it (IP). If the data link is made specifically for IP, as Ethernet and WiFi are, these will be the same size and packets will correspond to frames.

I've checked your source code and find to change to yellow you need to adds the yellow background color to : #left-padding, #right-padding, html, #hd, #main and #yui-main.

The better answers to this only work for specific lengths of lists that are provided.

Here's a version that works for any lengths of input. It also makes the algorithm clear in terms of the mathematical concepts of combination and permutation.

from itertools import combinations, permutations
list1 = ['1', '2']
list2 = ['A', 'B', 'C']

num_elements = min(len(list1), len(list2))
list1_combs = list(combinations(list1, num_elements))
list2_perms = list(permutations(list2, num_elements))
result = [
  tuple(zip(perm, comb))
  for comb in list1_combs
  for perm in list2_perms
]

for idx, ((l11, l12), (l21, l22)) in enumerate(result):
  print(f'{idx}: {l11}{l12} {l21}{l22}')

This outputs:

0: A1 B2
1: A1 C2
2: B1 A2
3: B1 C2
4: C1 A2
5: C1 B2

It depends on how you access the data:

Go for Option 1:

• If you use most of the fields on most of your accesses.
• If there is variance on possible keys

Go for Option 2:

• If you use just single fields on most of your accesses.
• If you always know which fields are available

P.S.: As a rule of the thumb, go for the option which requires fewer queries on most of your use cases.

No. It is not possible to share the same port at a particular instant. But you can make your application such a way that it will make the port access at different instant.

Seems a timestamp issue. According to tomcat documentation, if there is a new jsp or servlet this will create a new _java file in the work folder unless the _java.class files are newer than the jsp or servlets.

The startActivityForResult pattern is much better suited for what you're trying to achieve : http://developer.android.com/reference/android/app/Activity.html#StartingActivities

Try below code

public class MainActivity extends Activity {  

    Button button1;  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
        textView1=(TextView)findViewById(R.id.textView1);  
        button1=(Button)findViewById(R.id.button1);  
        button1.setOnClickListener(new OnClickListener() {  
            @Override  
            public void onClick(View arg0) {  
                Intent intent=new Intent(MainActivity.this,SecondActivity.class);  
                startActivityForResult(intent, 2);// Activity is started with requestCode 2  
            }  
        });  
    }  
 // Call Back method  to get the Message form other Activity  
    @Override  
       protected void onActivityResult(int requestCode, int resultCode, Intent data)  
       {  
                 super.onActivityResult(requestCode, resultCode, data);  
                  // check if the request code is same as what is passed  here it is 2  
                   if(requestCode==2)  
                         {  
                          //do the things u wanted 
                         }  
     }  

} 

SecondActivity.class

public class SecondActivity extends Activity {  

    Button button1;  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_second);  

            button1=(Button)findViewById(R.id.button1);  
            button1.setOnClickListener(new OnClickListener() {  
                @Override  
                public void onClick(View arg0) {  
                    String message="hello ";  
                    Intent intent=new Intent();  
                    intent.putExtra("MESSAGE",message);  
                    setResult(2,intent);  
                    finish();//finishing activity  
                }  
            });  
    }  

}  

Let me know if it helped...

Because a reference is 'managed', but not hydrated, it can also allow you to remove an entity by ID, without needing to load it into memory first.

As you can't remove an unmanaged entity, it's just plain silly to load all fields using find(...) or createQuery(...), only to immediately delete it.

MyLargeObject myObject = em.getReference(MyLargeObject.class, objectId);
em.remove(myObject);

Here's a version that actually uses the correct formula . :)

#! /usr/bin/env python

''' Calculate binomial coefficient xCy = x! / (y! (x-y)!)
'''

from math import factorial as fac


def binomial(x, y):
    try:
        return fac(x) // fac(y) // fac(x - y)
    except ValueError:
        return 0


#Print Pascal's triangle to test binomial()
def pascal(m):
    for x in range(m + 1):
        print([binomial(x, y) for y in range(x + 1)])


def main():
    #input = raw_input
    x = int(input("Enter a value for x: "))
    y = int(input("Enter a value for y: "))
    print(binomial(x, y))


if __name__ == '__main__':
    #pascal(8)
    main()

...

Here's an alternate version of binomial() I wrote several years ago that doesn't use math.factorial(), which didn't exist in old versions of Python. However, it returns 1 if r is not in range(0, n+1).

def binomial(n, r):
    ''' Binomial coefficient, nCr, aka the "choose" function 
        n! / (r! * (n - r)!)
    '''
    p = 1    
    for i in range(1, min(r, n - r) + 1):
        p *= n
        p //= i
        n -= 1
    return p

If you have integers in your file fscanf returns 1 until integer occurs. For example:

FILE *in = fopen("./task.in", "r");
int length = 0;
int counter;
int sequence;

for ( int i = 0; i < 10; i++ ) {
    counter = fscanf(in, "%d", &sequence);
    if ( counter == 1 ) {
        length += 1;
    }
}

To find out the end of the file with symbols you can use EOF. For example:

char symbol;
FILE *in = fopen("./task.in", "r");

for ( ; fscanf(in, "%c", &symbol) != EOF; ) {
    printf("%c", symbol); 
}

This answer is similar to @PaulMcG's answer but doesn't require sorting the input.

For those into functional programming, groupBy can be written in one line (not including imports!), and unlike itertools.groupby it doesn't require the input to be sorted:

from functools import reduce # import needed for python3; builtin in python2
from collections import defaultdict

def groupBy(key, seq):
 return reduce(lambda grp, val: grp[key(val)].append(val) or grp, seq, defaultdict(list))

(The reason for ... or grp in the lambda is that for this reduce() to work, the lambda needs to return its first argument; because list.append() always returns None the or will always return grp. I.e. it's a hack to get around python's restriction that a lambda can only evaluate a single expression.)

This returns a dict whose keys are found by evaluating the given function and whose values are a list of the original items in the original order. For the OP's example, calling this as groupBy(lambda pair: pair[1], input) will return this dict:

{'KAT': [('11013331', 'KAT'), ('9843236', 'KAT')],
 'NOT': [('9085267', 'NOT'), ('11788544', 'NOT')],
 'ETH': [('5238761', 'ETH'), ('5349618', 'ETH'), ('962142', 'ETH'), ('7795297', 'ETH'), ('7341464', 'ETH'), ('5594916', 'ETH'), ('1550003', 'ETH')]}

And as per @PaulMcG's answer the OP's requested format can be found by wrapping that in a list comprehension. So this will do it:

result = {key: [pair[0] for pair in values],
          for key, values in groupBy(lambda pair: pair[1], input).items()}

PHP will work only on the .php file extension.

If you are on Apache you can also set, in your httpd.conf file, the extensions for PHP. You'll have to find the line:

AddType application/x-httpd-php .php .html
                                     ^^^^^

and add how many extensions, that should be read with the PHP interpreter, as you want.

When scrolling is enabled in DataTables using scrollX or scrollY parameters, it will split the entire table into two or three individual HTML table elements; the header, the body and, optionally, the footer. This is done in order to provide the ability to scroll the different sections of the DataTable in a cross-browser manner.

In my case I wanted to have horizontal scroll bar because content are scrolling to right. So adding "scrollX" parameter created this issue in some of the pages which are having more columns.

Below code wrap a div around the DataTable with style "overflow as auto". We need to add div when dataTable completed the execution. We can do this as below:

$('#DataTableID').DataTable({
  //"scrollX": true,            
  "initComplete": function (settings, json) {  
    $("#DataTableID").wrap("<div style='overflow:auto; width:100%;position:relative;'></div>");            
  },
});

If you are using the scrollX,scrollY, scrollXInner or sScrollXInner options - remove them. They may cause problems.

Yes, see "Loading Page Fragments" on http://api.jquery.com/load/.

In short, you add the selector after the URL. For example:

$('#result').load('ajax/test.html #container');

To obtain a stream of just the names:

$ jq '.[] | select(.location=="Stockholm") | .name' json

produces:

"Donald"
"Walt"

To obtain a stream of corresponding (key name, "name" attribute) pairs, consider:

$ jq -c 'to_entries[]
        | select (.value.location == "Stockholm")
        | [.key, .value.name]' json

Output:

["FOO","Donald"]
["BAR","Walt"]

See the example code and demo at the bottom of the jquery documentation page:

http://api.jquery.com/mouseenter/

... mouseover fires when the pointer moves into the child element as well, while mouseenter fires only when the pointer moves into the bound element.

I use this function merge

CREATE OR REPLACE FUNCTION merge_tabla(key INT, data TEXT)

    IF EXISTS(SELECT a FROM tabla WHERE a = key)
        THEN
            UPDATE tabla SET b = data WHERE a = key;
        RETURN;
    ELSE
        INSERT INTO tabla(a,b) VALUES (key, data);
        RETURN;
    END IF;
END;

I was already using Pillow and got the same error. Tried installing libjpeg or libjpeg-dev as suggested by others but was told that a (newer) version was already installed.

In the end all it took was reinstalling Pillow:

sudo pip uninstall Pillow
sudo pip install Pillow

Try this.

public static void main(String[] args) {
    EchoServer0 myServer;
    myServer = new EchoServer0();
    myServer.listen();
}

What you were trying to do was declaring a variable of type Object, not creating anything for that variable to reference, then trying to call a method that didn't exist (in the class Object) on an object that hadn't been created. It was never going to work.

Using Nuget

1. Right click Project, select Manage NuGet packages...
2. Select the Browse tab, search for Oracle and install Oracle.ManagedDataAccess

3. In code use the following command (Ctrl+. to automatically add the using directive).

4. Note the different DataSource string which in comparison to Java is different.

   // create connection
   OracleConnection con = new OracleConnection();
   
   // create connection string using builder
   OracleConnectionStringBuilder ocsb = new OracleConnectionStringBuilder();
   ocsb.Password = "autumn117";
   ocsb.UserID = "john";
   ocsb.DataSource = "database.url:port/databasename";
   
   // connect
   con.ConnectionString = ocsb.ConnectionString;
   con.Open();
   Console.WriteLine("Connection established (" + con.ServerVersion + ")");
   

This is for Ubunutu 14.04:

In file /etc/apache2/apache2.conf it should be as below without the directory name:

<Directory /home/username>
    Options Indexes FollowSymLinks
    AllowOverride All
    Require all granted
</Directory>

And in file /etc/apache2/sites-available/000-default.conf you should include the custom directory name, i.e., www:

DocumentRoot /home/username/www

If it is not as above, it will give you an error when loading the server:

Forbidden You don't have permission to access / on this server

This is a function i used in the past for substracting a date from another one related with your question, my principe was to get how many days, hours minutes and seconds has left until a product has expired :

$expirationDate = strtotime("2015-01-12 20:08:23");
$toDay = strtotime(date('Y-m-d H:i:s'));
$difference = abs($toDay - $expirationDate);
$days = floor($difference / 86400);
$hours = floor(($difference - $days * 86400) / 3600);
$minutes = floor(($difference - $days * 86400 - $hours * 3600) / 60);
$seconds = floor($difference - $days * 86400 - $hours * 3600 - $minutes * 60);

echo "{$days} days {$hours} hours {$minutes} minutes {$seconds} seconds";

You can use the following:

plt.hold(True)

i thinking about this and i choose method accesor

why?

because field and methos accesor is the same but if later i need some logic in load field, i save move all annotation placed in fields

php://input can give you the raw bytes of the data. This is useful if the POSTed data is a JSON encoded structure, which is often the case for an AJAX POST request.

Here's a function to do just that:

  /**
   * Returns the JSON encoded POST data, if any, as an object.
   * 
   * @return Object|null
   */
  private function retrieveJsonPostData()
  {
    // get the raw POST data
    $rawData = file_get_contents("php://input");

    // this returns null if not valid json
    return json_decode($rawData);
  }

The $_POST array is more useful when you're handling key-value data from a form, submitted by a traditional POST. This only works if the POSTed data is in a recognised format, usually application/x-www-form-urlencoded (see http://www.w3.org/TR/html4/interact/forms.html#h-17.13.4 for details).

As it was said already @INC is an array and you're free to add anything you want.

My CGI REST script looks like:

#!/usr/bin/perl
use strict;
use warnings;
BEGIN {
    push @INC, 'fully_qualified_path_to_module_wiht_our_REST.pm';
}
use Modules::Rest;
gone(@_);

Subroutine gone is exported by Rest.pm.

Hashicorp's https://github.com/mitchellh/mapstructure library does this out of the box:

import "github.com/mitchellh/mapstructure"

mapstructure.Decode(myData, &result)

The second result parameter has to be an address of the struct.

What you are looking for is the POSIX blank character class. In Perl it is referenced as:

[[:blank:]]

in Java (don't forget to enable UNICODE_CHARACTER_CLASS):

\p{Blank}

Compared to the similar \h, POSIX blank is supported by a few more regex engines (reference). A major benefit is that its definition is fixed in Annex C: Compatibility Properties of Unicode Regular Expressions and standard across all regex flavors that support Unicode. (In Perl, for example, \h chooses to additionally include the MONGOLIAN VOWEL SEPARATOR.) However, an argument in favor of \h is that it always detects Unicode characters (even if the engines don't agree on which), while POSIX character classes are often by default ASCII-only (as in Java).

But the problem is that even sticking to Unicode doesn't solve the issue 100%. Consider the following characters which are not considered whitespace in Unicode:

• U+180E MONGOLIAN VOWEL SEPARATOR

• U+200B ZERO WIDTH SPACE

• U+200C ZERO WIDTH NON-JOINER

• U+200D ZERO WIDTH JOINER

• U+2060 WORD JOINER

• U+FEFF ZERO WIDTH NON-BREAKING SPACE

  _{Taken from https://en.wikipedia.org/wiki/White-space_character}

The aforementioned Mongolian vowel separator isn't included for what is probably a good reason. It, along with 200C and 200D, occur within words (AFAIK), and therefore breaks the cardinal rule that all other whitespace obeys: you can tokenize with it. They're more like modifiers. However, ZERO WIDTH SPACE, WORD JOINER, and ZERO WIDTH NON-BREAKING SPACE (if it used as other than a byte-order mark) fit the whitespace rule in my book. Therefore, I include them in my horizontal whitespace character class.

In Java:

static public final String HORIZONTAL_WHITESPACE = "[\\p{Blank}\\u200B\\u2060\\uFFEF]"

You can use date filter to convert in date and display in specific format.

In .ts file (typescript):

let dateString = '1968-11-16T00:00:00' 
let newDate = new Date(dateString);

In HTML:

{{dateString |  date:'MM/dd/yyyy'}}

Below are some formats which you can implement :

Backend:

public todayDate = new Date();

HTML :

<select>
<option value=""></option>
<option value="MM/dd/yyyy">[{{todayDate | date:'MM/dd/yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy">[{{todayDate | date:'EEEE, MMMM d, yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm a'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm:ss a'}}]</option>
<option value="MM/dd/yyyy h:mm a">[{{todayDate | date:'MM/dd/yyyy h:mm a'}}]</option>
<option value="MM/dd/yyyy h:mm:ss a">[{{todayDate | date:'MM/dd/yyyy h:mm:ss a'}}]</option>
<option value="MMMM d">[{{todayDate | date:'MMMM d'}}]</option>   
<option value="yyyy-MM-ddTHH:mm:ss">[{{todayDate | date:'yyyy-MM-ddTHH:mm:ss'}}]</option>
<option value="h:mm a">[{{todayDate | date:'h:mm a'}}]</option>
<option value="h:mm:ss a">[{{todayDate | date:'h:mm:ss a'}}]</option>      
<option value="EEEE, MMMM d, yyyy hh:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy hh:mm:ss a'}}]</option>
<option value="MMMM yyyy">[{{todayDate | date:'MMMM yyyy'}}]</option> 
</select>

You can try this one it is short :)

SystemClock.sleep(7000);

It will sleep for 7 sec look at documentation

Some commentors already stated that answers to your question will not work for all distributions. Since you did not include CentOS in the question but only in the tags, I'd like to post here the topics one has to understand in order to have a control over his/her proceeding regardless of the distribution:

1. what is the init daemon (optional)
2. what is the inittab file (/etc/inittab)
3. what does the inittab file do in your distro (e.g. does it actually run all scripts in /etc/init.d ?)

For your problem, one could start the script on sysinit by adding this line in /etc/inittab and make it respawn in case it terminates:

# start and respawn after termination
ttyS0::respawn:/bin/sh /path/to/my_script.sh

The script has to be made executable in advance of course:

chmod +x /path/to/my_script.sh

Hope this helps

When doing pan_list.append(p.last) you're doing an inplace operation, that is an operation that modifies the object and returns nothing (i.e. None).

You should do something like this :

last_list=[]
if p.last_name==None or p.last_name=="": 
    pass
last_list.append(p.last)  # Here I modify the last_list, no affectation
print last_list

You can do this with the following:

int counter = 0;
String sql = "SELECT projectName,Owner " + "FROM Project WHERE Owner= ?";
PreparedStatement prep = conn.prepareStatement(sql);
prep.setString(1, "");
ResultSet rs = prep.executeQuery();
while (rs.next()) {
    counter++;
}
System.out.println(counter);

This will give you the no of rows where the column value is null or blank.

Use Activtiy Context

Replace this

  final EditText input = new EditText(this);

By

  final EditText input = new EditText(MainActivity.this);  
  LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
                        LinearLayout.LayoutParams.MATCH_PARENT,
                        LinearLayout.LayoutParams.MATCH_PARENT);
  input.setLayoutParams(lp);
  alertDialog.setView(input); // uncomment this line

There's no such thing as an empty date per se, do you mean something like:

DateTime? myDateTime = null;

It's not because you are using alert, it will happen when use document.write() too. This problem generally arises when you name your id or class of any tag as same as any variable which you are using in you javascript code. Try by changing either the javascript variable name or by changing your tag's id/class name.

My code example: bank.html

<!doctype html>
<html>
<head>
    <title>Transaction Tracker</title>
    <script src="bank.js"></script> 
</head>
    <body>
        <div><button onclick="bitch()">Press me!</button></div>
    </body>
</html>

Javascript code: bank.js

function bitch(){ amt = 0;
var a = Math.random(); ran = Math.floor(a * 100);
return ran; }

function all(){
amt = amt + bitch(); document.write(amt + "
"); } setInterval(all,2000);

you can have a look and understand the concept from my code. Here i have used a variable named 'amt' in JS. You just try to run my code. It will work fine but as you put an [id="amt"](without square brackets) (which is a variable name in JS code )for div tag in body of html you will see the same error that you are talking about. So simple solution is to change either the variable name or the id or class name.

Hopefully I'm not late for the party.

Encountered this using Eclipse Kepler and Maven 3.1.

The solution is to use a JDK and not a JRE for your Eclipse project. Make sure to try maven clean and test from eclipse just to download missing jars.

Or if you want a simple one-liner:

Person person = JAXB.unmarshal(new StringReader("<?xml ..."), Person.class);

You could also use string[] something = text.Split('@'). Make sure you use single quotes to surround the "@" to store it as a char type. This will store the characters up to and including each "@" as individual words in the array. You can then output each (element + System.Environment.NewLine) using a for loop or write it to a text file using System.IO.File.WriteAllLines([file path + name and extension], [array name]). If the specified file doesn't exist in that location it will be automatically created.

Broadcast Receivers timeout after 10 seconds. Possibly your doing an asynchronous call (wrong) from a broadcast receiver and 4.3 actually detects it.

If you are mocking the behavior (with something like doNothing()) there should really be no need to call to verify*(). That said, here's my stab at re-writing your test method:

@PrepareForTest({InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest { //Note the renaming of the test class.
   public void testProcessOrder() {
        //Variables
        InternalService is = new InternalService();
        Order order = mock(Order.class);

        //Mock Behavior
        when(order.isSuccessful()).thenReturn(true);
        mockStatic(Internalutils.class);
        doNothing().when(InternalUtils.class); //This is the preferred way
                                               //to mock static void methods.
        InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

        //Execute
        is.processOrder(order);            

        //Verify
        verifyStatic(InternalUtils.class); //Similar to how you mock static methods
                                           //this is how you verify them.
        InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
   }
}

I grouped into four sections to better highlight what is going on:

1. Variables

I choose to declare any instance variables / method arguments / mock collaborators here. If it is something used in multiple tests, consider making it an instance variable of the test class.

2. Mock Behavior

This is where you define the behavior of all of your mocks. You're setting up return values and expectations here, prior to executing the code under test. Generally speaking, if you set the mock behavior here you wouldn't need to verify the behavior later.

3. Execute

Nothing fancy here; this just kicks off the code being tested. I like to give it its own section to call attention to it.

4. Verify

This is when you call any method starting with verify or assert. After the test is over, you check that the things you wanted to have happen actually did happen. That is the biggest mistake I see with your test method; you attempted to verify the method call before it was ever given a chance to run. Second to that is you never specified which static method you wanted to verify.

Additional Notes

This is mostly personal preference on my part. There is a certain order you need to do things in but within each grouping there is a little wiggle room. This helps me quickly separate out what is happening where.

I also highly recommend going through the examples at the following sites as they are very robust and can help with the majority of the cases you'll need:

• https://github.com/powermock/powermock/wiki/Mockito (PowerMock Overview / Examples)
• http://site.mockito.org/mockito/docs/current/org/mockito/Mockito.html (Mockito Overview / Examples)

Another way to resolve this is to use the _token field in ajax data and set the value of {{csrf_token()}} in blade. Here is a working code that I just tried at my end.

$.ajax({
    type: "POST",
    url: '/your_url',
    data: { somefield: "Some field value", _token: '{{csrf_token()}}' },
    success: function (data) {
       console.log(data);
    },
    error: function (data, textStatus, errorThrown) {
        console.log(data);

    },
});

The timezone name is the only reliable way to specify the timezone.

You can find a list of timezone names here: http://en.wikipedia.org/wiki/List_of_tz_database_time_zones Note that this list contains a lot of alias names, such as US/Eastern for the timezone that is properly called America/New_York.

If you programatically want to create this list from the zoneinfo database you can compile it from the zone.tab file in the zoneinfo database. I don't think pytz has an API to get them, and I also don't think it would be very useful.

Just do one thing, We need to set the name property for the same types. for eg.

Try below:

<form>
    <div id="group1">
        <input type="radio" value="val1" name="group1">
        <input type="radio" value="val2" name="group1">
    </div>
</form>

And also we can do it in angular1,angular 2 or in jquery also.

<div *ngFor="let option of question.options; index as j">
<input type="radio" name="option{{j}}" value="option{{j}}" (click)="checkAnswer(j+1)">{{option}}
</div>  

To get the number of full months between two dates:

import datetime

def difference_in_months(start, end):
    if start.year == end.year:
        months = end.month - start.month
    else:
        months = (12 - start.month) + (end.month)

    if start.day > end.day:
        months = months - 1

    return months

The second quote is correct, the size of a word varies from computer to computer. The ARM NEON architecture is an example of an architecture with 32-bit words, where 64-bit quantities are referred to as "doublewords" and 128-bit quantities are referred to as "quadwords":

A NEON operand can be a vector or a scalar. A NEON vector can be a 64-bit doubleword vector or a 128-bit quadword vector.

Normally speaking, 16-bit words are only found on 16-bit systems, like the Amiga 500.

caution : It is not recommended to remove the default Python from Ubuntu, it may cause GDM(Graphical Display Manager, that provide graphical login capabilities) failed.

To completely uninstall Python2.x.x and everything depends on it. use this command:

sudo apt purge python2.x-minimal

As there are still a lot of packages that depend on Python2.x.x. So you should have a close look at the packages that apt wants to remove before you let it proceed.

Thanks, I hope it will be helpful for you.

That should be simple. Try this:

var idList = new int[1, 2, 3, 4, 5];
var userProfiles = _dataContext.UserProfile.Where(e => idList.Contains(e));

For Mac users make sure to sudo and when prompted first give your administrator password and that will be followed by keystore password which typically should be "changeit" unless you actually changed it.

Try This...

Go to your notification area in the taskbar.

Right click on Bluestacks Agent>Rotate Portrait Apps>Enabled.

There are several options available..

a. Automatic - Selected By Default - It will rotate the app player in portrait mode for portrait apps.

b. Disabled - It will force the portrait apps to work in landscape mode.

c. Enabled - It will force the portrait apps to work in portrait mode only.

This May help you..

I was looking for a different problem and came across this, so I will add my solution to a related problem: comparing two Maps.

    // make a copy of the data
    Map<String,String> a = new HashMap<String,String>(actual);
    Map<String,String> e = new HashMap<String,String>(expected);
    // check *every* expected value
    for(Map.Entry<String, String> val : e.entrySet()){
        // check for presence
        if(!a.containsKey(val.getKey())){
            System.out.println(String.format("Did not find expected value: %s", val.getKey()));
        }
        // check for equality
        else{
            if(0 != a.get(val.getKey()).compareTo(val.getValue())){
                System.out.println(String.format("Value does not match expected: %s", val.getValue()));
            }
            // we have found the item, so remove it 
            // from future consideration. While it 
            // doesn't affect Java Maps, other types of sets
            // may contain duplicates, this will flag those
            // duplicates. 
            a.remove(val.getKey());
        }
    }
    // check to see that we did not receive extra values
    for(Map.Entry<String,String> val : a.entrySet()){
        System.out.println(String.format("Found unexpected value: %s", val.getKey()));
    }

It works on the same principle as the other solutions but also compares not only that values are present, but that they contain the same value. Mostly I've used this in accounting software when comparing data from two sources (Employee and Manager entered values match; Customer and Corporate transactions match; ... etc)

Microsoft provided an explanation of the MVVM Pattern in the Windows environment here.

Here's a crucial section:

In the Model-View-ViewModel design pattern, an app is composed of three general components.

• Model: This represents the data model that your app consumes. For example, in a picture sharing app, this layer might represent the set of pictures available on a device and the API used to read and write to the picture library.

• View: An app typically is composed of multiple pages of UI. Each page shown to the user is a view in MVVM terminology. The view is the XAML code used to define and style what the user sees. The data from the model is displayed to the user, and it’s the job of the ViewModel to feed the UI this data based on the current state of the app. For example, in a picture sharing app, the views would be the UI that show the user the list of albums on the device, the pictures in an album, and perhaps another that shows the user a particular picture.

• ViewModel: The ViewModel ties the data model, or simply the model, to the UI, or views, of the app. It contains the logic with which to manage the data from the model and exposes the data as a set of properties to which the XAML UI, or views, can bind. For example, in a picture sharing app, the ViewModel would expose a list of albums, and for each album expose a list of pictures. The UI is agnostic of where the pictures come from and how they are retrieved. It simply knows of a set of pictures as exposed by the ViewModel and shows them to the user.

From plt.imshow() official guide, we know that aspect controls the aspect ratio of the axes. Well in my words, the aspect is exactly the ratio of x unit and y unit. Most of the time we want to keep it as 1 since we do not want to distort out figures unintentionally. However, there is indeed cases that we need to specify aspect a value other than 1. The questioner provided a good example that x and y axis may have different physical units. Let's assume that x is in km and y in m. Hence for a 10x10 data, the extent should be [0,10km,0,10m] = [0, 10000m, 0, 10m]. In such case, if we continue to use the default aspect=1, the quality of the figure is really bad. We can hence specify aspect = 1000 to optimize our figure. The following codes illustrate this method.

%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt
rng=np.random.RandomState(0)
data=rng.randn(10,10)
plt.imshow(data, origin = 'lower',  extent = [0, 10000, 0, 10], aspect = 1000)

Nevertheless, I think there is an alternative that can meet the questioner's demand. We can just set the extent as [0,10,0,10] and add additional xy axis labels to denote the units. Codes as follows.

plt.imshow(data, origin = 'lower',  extent = [0, 10, 0, 10])
plt.xlabel('km')
plt.ylabel('m')

To make a correct figure, we should always bear in mind that x_max-x_min = x_res * data.shape[1] and y_max - y_min = y_res * data.shape[0], where extent = [x_min, x_max, y_min, y_max]. By default, aspect = 1, meaning that the unit pixel is square. This default behavior also works fine for x_res and y_res that have different values. Extending the previous example, let's assume that x_res is 1.5 while y_res is 1. Hence extent should equal to [0,15,0,10]. Using the default aspect, we can have rectangular color pixels, whereas the unit pixel is still square!

plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10])
# Or we have similar x_max and y_max but different data.shape, leading to different color pixel res.
data=rng.randn(10,5)
plt.imshow(data, origin = 'lower',  extent = [0, 5, 0, 5])

The aspect of color pixel is x_res / y_res. setting its aspect to the aspect of unit pixel (i.e. aspect = x_res / y_res = ((x_max - x_min) / data.shape[1]) / ((y_max - y_min) / data.shape[0])) would always give square color pixel. We can change aspect = 1.5 so that x-axis unit is 1.5 times y-axis unit, leading to a square color pixel and square whole figure but rectangular pixel unit. Apparently, it is not normally accepted.

data=rng.randn(10,10)
plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10], aspect = 1.5)

The most undesired case is that set aspect an arbitrary value, like 1.2, which will lead to neither square unit pixels nor square color pixels.

plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10], aspect = 1.2)

Long story short, it is always enough to set the correct extent and let the matplotlib do the remaining things for us (even though x_res!=y_res)! Change aspect only when it is a must.

Correct solution is to copy or install to /usr/local/bin not /usr/bin.This is due to System Integrity Protection (SIP). SIP makes /usr/bin read-only but leaves /usr/local as read-write.

SIP should not be disabled as stated in the answer above because it adds another layer of protection against malware gaining root access. Here is a complete explanation of what SIP does and why it is useful.

As suggested in this answer one should not disable SIP (rootless mode) "It is not recommended to disable rootless mode! The best practice is to install custom stuff to "/usr/local" only."

I also got the same error but I noticed that I had typed in Foreign*k*ey and not Foreign*K*ey,(capital K) if there is a newbie out there, check out spelling and caps.

In this state:

The thread is reading and processing rows for a SELECT statement, and sending data to the client.

Because operations occurring during this this state tend to perform large amounts of disk access (reads).

That's why it takes more time to complete and so is the longest-running state over the lifetime of a given query.

I assume you mean the <select> input element?

Support for that is pretty new, but FF 3.6, Chrome and IE 8 render this all right:

<select name="select">
  <option value="1" style="background-color: blue">Test</option>
  <option value="2" style="background-color: green">Test</option>
</select>
