Here is what I use:

import Foundation
import CoreLocation
import UIKit

class BackgroundLocationManager :NSObject, CLLocationManagerDelegate {

    static let instance = BackgroundLocationManager()
    static let BACKGROUND_TIMER = 150.0 // restart location manager every 150 seconds
    static let UPDATE_SERVER_INTERVAL = 60 * 60 // 1 hour - once every 1 hour send location to server

    let locationManager = CLLocationManager()
    var timer:NSTimer?
    var currentBgTaskId : UIBackgroundTaskIdentifier?
    var lastLocationDate : NSDate = NSDate()

    private override init(){
        super.init()
        locationManager.delegate = self
        locationManager.desiredAccuracy = kCLLocationAccuracyKilometer
        locationManager.activityType = .Other;
        locationManager.distanceFilter = kCLDistanceFilterNone;
        if #available(iOS 9, *){
            locationManager.allowsBackgroundLocationUpdates = true
        }

        NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.applicationEnterBackground), name: UIApplicationDidEnterBackgroundNotification, object: nil)
    }

    func applicationEnterBackground(){
        FileLogger.log("applicationEnterBackground")
        start()
    }

    func start(){
        if(CLLocationManager.authorizationStatus() == CLAuthorizationStatus.AuthorizedAlways){
            if #available(iOS 9, *){
                locationManager.requestLocation()
            } else {
                locationManager.startUpdatingLocation()
            }
        } else {
                locationManager.requestAlwaysAuthorization()
        }
    }
    func restart (){
        timer?.invalidate()
        timer = nil
        start()
    }

    func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
        switch status {
        case CLAuthorizationStatus.Restricted:
            //log("Restricted Access to location")
        case CLAuthorizationStatus.Denied:
            //log("User denied access to location")
        case CLAuthorizationStatus.NotDetermined:
            //log("Status not determined")
        default:
            //log("startUpdatintLocation")
            if #available(iOS 9, *){
                locationManager.requestLocation()
            } else {
                locationManager.startUpdatingLocation()
            }
        }
    }
    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

        if(timer==nil){
            // The locations array is sorted in chronologically ascending order, so the
            // last element is the most recent
            guard let location = locations.last else {return}

            beginNewBackgroundTask()
            locationManager.stopUpdatingLocation()
            let now = NSDate()
            if(isItTime(now)){
                //TODO: Every n minutes do whatever you want with the new location. Like for example sendLocationToServer(location, now:now)
            }
        }
    }

    func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
        CrashReporter.recordError(error)

        beginNewBackgroundTask()
        locationManager.stopUpdatingLocation()
    }

    func isItTime(now:NSDate) -> Bool {
        let timePast = now.timeIntervalSinceDate(lastLocationDate)
        let intervalExceeded = Int(timePast) > BackgroundLocationManager.UPDATE_SERVER_INTERVAL
        return intervalExceeded;
    }

    func sendLocationToServer(location:CLLocation, now:NSDate){
        //TODO
    }

    func beginNewBackgroundTask(){
        var previousTaskId = currentBgTaskId;
        currentBgTaskId = UIApplication.sharedApplication().beginBackgroundTaskWithExpirationHandler({
            FileLogger.log("task expired: ")
        })
        if let taskId = previousTaskId{
            UIApplication.sharedApplication().endBackgroundTask(taskId)
            previousTaskId = UIBackgroundTaskInvalid
        }

        timer = NSTimer.scheduledTimerWithTimeInterval(BackgroundLocationManager.BACKGROUND_TIMER, target: self, selector: #selector(self.restart),userInfo: nil, repeats: false)
    }
}

I start the tracking in AppDelegate like that:

BackgroundLocationManager.instance.start()

On a Windows box, I wanted to avoid reboot and these did not work: * /android/adt-bundle-windows/sdk/platform-tools/adb kill-server * /android/adt-bundle-windows/sdk/platform-tools/adb start-server

So what did work to get adb running again without this error was

1. wait for the TIME WAIT to complete, which took multiple minutes. You can view the state of the ports and watch when to restart the debugger with this command: "PortQryV2/PortQry.exe -local" This tools is downloaded here: http://support.microsoft.com/?id=832919

2. force closing ports with "netsh int tcp reset"

In version 3, they changed "export" to "unload". It still functions more or less the same.

I used to write my own error logging until I discovered ELMAH. I've never been able to get the emailing part down quite as perfectly as ELMAH does.

startActivity(new Intent(context, ListofProducts.class)
    .setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
    .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
    .setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK));

Different version similar to the one offered by Maxim Shoustin

I liked the answer but the part that bothered me was the use of <script id="..."> as a container for the modal's template.

I wanted to place the modal's template in a hidden <div> and bind the inner html with a scope variable called modal_html_template mainly because i think it more correct (and more comfortable to process in WebStorm/PyCharm) to place the template's html inside a <div> instead of <script id="...">

this variable will be used when calling $modal({... 'template': $scope.modal_html_template, ...})

in order to bind the inner html, i created inner-html-bind which is a simple directive

check out the example plunker

<div ng-controller="ModalDemoCtrl">

    <div inner-html-bind inner-html="modal_html_template" class="hidden">
        <div class="modal-header">
            <h3>I'm a modal!</h3>
        </div>
        <div class="modal-body">
            <ul>
                <li ng-repeat="item in items">
                    <a ng-click="selected.item = item">{{ item }}</a>
                </li>
            </ul>
            Selected: <b>{{ selected.item }}</b>
        </div>
        <div class="modal-footer">
            <button class="btn btn-primary" ng-click="ok()">OK</button>
            <button class="btn btn-warning" ng-click="cancel()">Cancel</button>
        </div>
    </div>

    <button class="btn" ng-click="open()">Open me!</button>
    <div ng-show="selected">Selection from a modal: {{ selected }}</div>
</div>

inner-html-bind directive:

app.directive('innerHtmlBind', function() {
  return {
    restrict: 'A',
    scope: {
      inner_html: '=innerHtml'
    },
    link: function(scope, element, attrs) {
      scope.inner_html = element.html();
    }
  }
});

I always have to look this one up time and time again, so here is my answer.

Asserting multiple method calls on different objects of the same class

Suppose we have a heavy duty class (which we want to mock):

In [1]: class HeavyDuty(object):
   ...:     def __init__(self):
   ...:         import time
   ...:         time.sleep(2)  # <- Spends a lot of time here
   ...:     
   ...:     def do_work(self, arg1, arg2):
   ...:         print("Called with %r and %r" % (arg1, arg2))
   ...:  

here is some code that uses two instances of the HeavyDuty class:

In [2]: def heavy_work():
   ...:     hd1 = HeavyDuty()
   ...:     hd1.do_work(13, 17)
   ...:     hd2 = HeavyDuty()
   ...:     hd2.do_work(23, 29)
   ...:    

Now, here is a test case for the heavy_work function:

In [3]: from unittest.mock import patch, call
   ...: def test_heavy_work():
   ...:     expected_calls = [call.do_work(13, 17),call.do_work(23, 29)]
   ...:     
   ...:     with patch('__main__.HeavyDuty') as MockHeavyDuty:
   ...:         heavy_work()
   ...:         MockHeavyDuty.return_value.assert_has_calls(expected_calls)
   ...:  

We are mocking the HeavyDuty class with MockHeavyDuty. To assert method calls coming from every HeavyDuty instance we have to refer to MockHeavyDuty.return_value.assert_has_calls, instead of MockHeavyDuty.assert_has_calls. In addition, in the list of expected_calls we have to specify which method name we are interested in asserting calls for. So our list is made of calls to call.do_work, as opposed to simply call.

Exercising the test case shows us it is successful:

In [4]: print(test_heavy_work())
None

If we modify the heavy_work function, the test fails and produces a helpful error message:

In [5]: def heavy_work():
   ...:     hd1 = HeavyDuty()
   ...:     hd1.do_work(113, 117)  # <- call args are different
   ...:     hd2 = HeavyDuty()
   ...:     hd2.do_work(123, 129)  # <- call args are different
   ...:     

In [6]: print(test_heavy_work())
---------------------------------------------------------------------------
(traceback omitted for clarity)

AssertionError: Calls not found.
Expected: [call.do_work(13, 17), call.do_work(23, 29)]
Actual: [call.do_work(113, 117), call.do_work(123, 129)]

Asserting multiple calls to a function

To contrast with the above, here is an example that shows how to mock multiple calls to a function:

In [7]: def work_function(arg1, arg2):
   ...:     print("Called with args %r and %r" % (arg1, arg2))

In [8]: from unittest.mock import patch, call
   ...: def test_work_function():
   ...:     expected_calls = [call(13, 17), call(23, 29)]    
   ...:     with patch('__main__.work_function') as mock_work_function:
   ...:         work_function(13, 17)
   ...:         work_function(23, 29)
   ...:         mock_work_function.assert_has_calls(expected_calls)
   ...:    

In [9]: print(test_work_function())
None

There are two main differences. The first one is that when mocking a function we setup our expected calls using call, instead of using call.some_method. The second one is that we call assert_has_calls on mock_work_function, instead of on mock_work_function.return_value.

You can copy the files into an appropriately named subdirectory directory of the data folder as long as it is the EXACT same version of mySQL and you have retained all of the associated files in that directory. If you don't have all the files, I'm pretty sure you're going to have issues.

my answer is transposed of 3x3 matrix

 #include<iostream.h>

#include<math.h>


main()
{
int a[3][3];
int b[3];
cout<<"You must give us an array 3x3 and then we will give you Transposed it "<<endl;
for(int i=0;i<3;i++)
{
    for(int j=0;j<3;j++)
{
cout<<"Enter a["<<i<<"]["<<j<<"]: ";

cin>>a[i][j];

}

}
cout<<"Matrix you entered is :"<<endl;

 for (int e = 0 ; e < 3 ; e++ )

{
    for ( int f = 0 ; f < 3 ; f++ )

        cout << a[e][f] << "\t";


    cout << endl;

    }

 cout<<"\nTransposed of matrix you entered is :"<<endl;
 for (int c = 0 ; c < 3 ; c++ )
{
    for ( int d = 0 ; d < 3 ; d++ )
        cout << a[d][c] << "\t";

    cout << endl;
    }

return 0;
}

I had the same problem but finally I found the way.

Here is the walk through:

1- Install VLC on your computer (SERVER) and go to Media->Streaming (Ctrl+S)

2- Select a file to stream or if you want to stream your webcam or... click on "Capture Device" tab and do the configuration and finally click on "Stream" button.

3- Here you should do the streaming server configuration, just go to "Option" tab and paste the following command:

:sout=#transcode{vcodec=mp4v,vb=400,fps=10,width=176,height=144,acodec=mp4a,ab=32,channels=1,samplerate=22050}:rtp{sdp=rtsp://YOURCOMPUTER_SERVER_IP_ADDR:5544/}

NOTE: Replace YOURCOMPUTER_SERVER_IP_ADDR with your computer IP address or any server which is running VLC...

NOTE: You can see, the video codec is MP4V which is supported by android.

4- go to eclipse and create a new project for media playbak. create a VideoView object and in the OnCreate() function write some code like this:

mVideoView = (VideoView) findViewById(R.id.surface_view);

mVideoView.setVideoPath("rtsp://YOURCOMPUTER_SERVER_IP_ADDR:5544/");
mVideoView.setMediaController(new MediaController(this));

5- run the apk on the device (not simulator, i did not check it) and wait for the playback to be started. please consider the buffering process will take about 10 seconds...

Question: Anybody know how to reduce buffering time and play video almost live ?

Hash code is used for hash-based collections like Dictionary, Hashtable, HashSet etc. The purpose of this code is to very quickly pre-sort specific object by putting it into specific group (bucket). This pre-sorting helps tremendously in finding this object when you need to retrieve it back from hash-collection because code has to search for your object in just one bucket instead of in all objects it contains. The better distribution of hash codes (better uniqueness) the faster retrieval. In ideal situation where each object has a unique hash code, finding it is an O(1) operation. In most cases it approaches O(1).

Why not try this?

html:

<p>
  a b c
</p>

js:

$("p").text().trim();

I use cookie to define if i want desktop or responsive version. In the footer of the page you can find two spans and in general.js is the script to handle the clicks.

        <div class="col-xs-6" style="text-align:center;"><span class="make_desktop">Desktop</span></div>
        <div class="col-xs-6" style="text-align:center;"><span class="make_responsive">Mobile</span></div>

function setMobDeskCookie(c_name, value, exdays) {
    var exdate = new Date();
    exdate.setDate(exdate.getDate() + exdays);
    var c_value = escape(value) + ((exdays === null) ? "" : "; expires=" + exdate.toUTCString());
    document.cookie = c_name + "=" + c_value + "; path=/";
    window.location.reload();
}

$(function() {
    $(".make_desktop").click(function() {
        setMobDeskCookie('deskmob', 1, 3650);
    });
    $(".make_responsive").click(function() {
        setMobDeskCookie('deskmob', 0, 3650);
    });
});`enter code here`

i ended up splitting all my custom css into two files i don't use bootstrap navigation but my own so that is majority of my custom styles, so it will not resolve your entire problem but it works for me

and i also created non-responsive.css that forces the grid to maintain the large screen version

in case u select mobile i would load / echo

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">  
<!-- Bootstrap core CSS and JS -->
        <script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
        <link href="/themes/responsive_lime/bootstrap-3_1_1/css/bootstrap.css" rel="stylesheet">
        <script src="/themes/responsive_lime/bootstrap-3_1_1/js/bootstrap.min.js"></script>

and load these stylesheets
<link rel="stylesheet" type="text/css" media="screen,print" href="/themes/responsive_lime/css/style.css?modified=14-06-2014-12-27-40" />
<link rel="stylesheet" type="text/css" media="screen,print" href="/themes/responsive_lime/css/style-responsive.css?modified=1402758346" />

in case you select desktop i would load /echo

<meta name="viewport" content="width=1024">    


        <!-- Bootstrap core CSS and JS -->
        <script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
        <link href="/themes/responsive_lime/bootstrap-3_1_1/css/bootstrap.css" rel="stylesheet">
        <script src="/themes/responsive_lime/bootstrap-3_1_1/js/bootstrap.min.js"></script>

        <!-- Main CSS -->
        <link rel="stylesheet" type="text/css" media="screen,print" href="/themes/responsive_lime/css/style.css?modified=14-06-2014-12-27-40" />
<link rel="stylesheet" type="text/css" media="screen,print" href="/themes/responsive_lime/css/non-responsive.css?modified=1402758635" />

the non-responsive.css is the one that has overrides for bootstrap my concern is layout so there is not much in there, given that i handle the navigation in my own way so css for it and the other bits is in my other css files

please note that my setup does behave as desktop even on desktop browsers unlike some other solutions i have seen that will only ignore the viewport that seems to have wotked only on mobile devices for me

Everyone is correct. However, if you're also busy testing your code your own application might still "own" the socket if it starts and stops relatively quickly. Try SO_REUSEADDR as a socket option:

What exactly does SO_REUSEADDR do?

This socket option tells the kernel that even if this port is busy (in the TIME_WAIT state), go ahead and reuse it anyway. If it is busy, but with another state, you will still get an address already in use error. It is useful if your server has been shut down, and then restarted right away while sockets are still active on its port. You should be aware that if any unexpected data comes in, it may confuse your server, but while this is possible, it is not likely.

It has been pointed out that "A socket is a 5 tuple (proto, local addr, local port, remote addr, remote port). SO_REUSEADDR just says that you can reuse local addresses. The 5 tuple still must be unique!" by Michael Hunter ([email protected]). This is true, and this is why it is very unlikely that unexpected data will ever be seen by your server. The danger is that such a 5 tuple is still floating around on the net, and while it is bouncing around, a new connection from the same client, on the same system, happens to get the same remote port. This is explained by Richard Stevens in ``2.7 Please explain the TIME_WAIT state.''.

Execute this at the terminal to see conflicting configurations listening to the same port:

grep -R default_server /etc/nginx

i had the same issue and niether of the above resoved it. It turns out there was an old sql task that was disabled on the bottom right corner of my ssis that i really had to look for to find. Once i deleted this all was well

The hold on feature is switched on by default in matplotlib.pyplot. So each time you evoke plt.plot() before plt.show() a drawing is added to the plot. Launching plt.plot() after the function plt.show() leads to redrawing the whole picture.

Here's the Scalatest page on using the runner and the extended discussion on the -t and -z options.

This post shows what commands work for a test file that uses FunSpec.

Here's the test file:

package com.github.mrpowers.scalatest.example

import org.scalatest.FunSpec

class CardiBSpec extends FunSpec {

  describe("realName") {

    it("returns her birth name") {
      assert(CardiB.realName() === "Belcalis Almanzar")
    }

  }

  describe("iLike") {

    it("works with a single argument") {
      assert(CardiB.iLike("dollars") === "I like dollars")
    }

    it("works with multiple arguments") {
      assert(CardiB.iLike("dollars", "diamonds") === "I like dollars, diamonds")
    }

    it("throws an error if an integer argument is supplied") {
      assertThrows[java.lang.IllegalArgumentException]{
        CardiB.iLike()
      }
    }

    it("does not compile with integer arguments") {
      assertDoesNotCompile("""CardiB.iLike(1, 2, 3)""")
    }

  }

}

This command runs the four tests in the iLike describe block (from the SBT command line):

testOnly *CardiBSpec -- -z iLike

You can also use quotation marks, so this will also work:

testOnly *CardiBSpec -- -z "iLike"

This will run a single test:

testOnly *CardiBSpec -- -z "works with multiple arguments"

This will run the two tests that start with "works with":

testOnly *CardiBSpec -- -z "works with"

I can't get the -t option to run any tests in the CardiBSpec file. This command doesn't run any tests:

testOnly *CardiBSpec -- -t "works with multiple arguments"

Looks like the -t option works when tests aren't nested in describe blocks. Let's take a look at another test file:

class CalculatorSpec extends FunSpec {
  it("adds two numbers") {
    assert(Calculator.addNumbers(3, 4) === 7)
  }
}

-t can be used to run the single test:

testOnly *CalculatorSpec -- -t "adds two numbers"

-z can also be used to run the single test:

testOnly *CalculatorSpec -- -z "adds two numbers"

See this repo if you'd like to run these examples. You can find more info on running tests here.

Your Activity is extending ActionBarActivity which requires the AppCompat.theme to be applied. Change from ActionBarActivity to Activity or FragmentActivity, it will solve the problem.

If you use no Action bar then :

android:theme="@android:style/Theme.Light.NoTitleBar.Fullscreen" 

Yes, add the System.Security assembly, import the System.Security.Cryptography namespace. Here's a simple example of a symmetric (DES) algorithm encryption:

DESCryptoServiceProvider des = new DESCryptoServiceProvider();
des.GenerateKey();
byte[] key = des.Key; // save this!

ICryptoTransform encryptor = des.CreateEncryptor();
// encrypt
byte[] enc = encryptor.TransformFinalBlock(new byte[] { 1, 2, 3, 4 }, 0, 4);

ICryptoTransform decryptor = des.CreateDecryptor();

// decrypt
byte[] originalAgain = decryptor.TransformFinalBlock(enc, 0, enc.Length);
Debug.Assert(originalAgain[0] == 1);

For benchmarking, like in your example, I use the pear Benchmark package. You set markers for measuring. The class also provides a few presentation helpers, or you can process the data as you see fit.

I actually have it wrapped in another class with a __destruct method. When a script exits, the output is logged via log4php to syslog, so I have a lot of performance data to work from.

To anyone who doesn't want to use DATE_SUB, use CURRENT_DATE:

SELECT CURRENT_DATE - INTERVAL 30 DAY

You can't. Variables defined inside a method are local to that method.

If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).

Looks like you're using instance methods instead of static ones.

If you don't want to create an object, you should declare all your methods static, so something like

private static void methodName(Argument args...)

If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.

private static int[][] array = new int[3][5];

Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.

Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.

Here's a final (shortened) example of what your code should be like:

public class Test3 {
    //Use this array in your methods
    private static int[][] scores = new int[3][5];

    /* Rather than just "Scores" name it so people know what
     * to expect
     */
    private static void createScores() {
        //Code...
    }
    //Other methods...

    /* Since you're now using static methods, you don't 
     * have to initialise an object and call its methods.
     */
    public static void main(String[] args){
        createScores();
        MD();   //Don't know what these do
        sumD(); //so I'll leave them.
    }
}

Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.

I was facing the same problem and non of the above solutions helped me. In my Web Api 2 project, I had actually updated my database and had placed a unique constraint on an SQL table column. That was actually causing the problem. Simply Checking the the duplicate column values before inserting helped me fix the problem!

gem install shutup

then go in the current folder of your rails project and run

shutup # this will kill the Rails process currently running

You can use the command 'shutup' every time you want

DICLAIMER: I am the creator of this gem

NOTE: if you are using rvm install the gem globally

rvm @global do gem install shutup

System.Threading.Thread.Sleep(50);

Remember though, that doing this in the main GUI thread will block your GUI from updating (it will feel "sluggish")

Just remove the ; to make it work for VB.net as well.

There is no definitive answer to this because "software architecture" and "software design" have quite a number of definitions and there isn't a canonical definition for either.

A good way of thinking of it is Len Bass, Paul Clements and Rick Kazman's statement that "all architecture is design but not all design is architecture" [Software Architecture in Practice]. I'm not sure I quite agree with that (because architecture can include other activities) but it captures the essence that architecture is a design activity that deals with the critical subset of design.

My slightly flippant definition (found on the SEI definitions page) is that it's the set of decisions which, if made wrongly, cause your project to get cancelled.

A useful attempt at separating architecture, design and implementation as concepts was done by Amnon Eden and Rick Kazman some years ago in a research paper entitled "Architecture, Design, Implementation" which can be found here: http://www.sei.cmu.edu/library/assets/ICSE03-1.pdf. Their language is quite abstract but simplistically they say that architecture is design that can be used in many contexts and is meant to be applied across the system, design is (err) design that can be used in many contexts but is applied in a specific part of the system, and implementation is design specific to a context and applied in that context.

So an architectural decision could be a decision to integrate the system via messaging rather than RPC (so it's a general principle that could be applied in many places and is intended to apply to the whole system), a design decision might be to use a master/slave thread structure in the input request handling module of the system (a general principle that could be used anywhere but in this case is just used in one module) and finally, an implementation decision might be to move responsibilities for security from the Request Router to the Request Handler in the Request Manager module (a decision relevant only to that context, used in that context).

I hope this helps!

Because the compiled JavaScript has all the type information erased, you can't use T to new up an object.

You can do this in a non-generic way by passing the type into the constructor.

class TestOne {
    hi() {
        alert('Hi');
    }
}

class TestTwo {
    constructor(private testType) {

    }
    getNew() {
        return new this.testType();
    }
}

var test = new TestTwo(TestOne);

var example = test.getNew();
example.hi();

You could extend this example using generics to tighten up the types:

class TestBase {
    hi() {
        alert('Hi from base');
    }
}

class TestSub extends TestBase {
    hi() {
        alert('Hi from sub');
    }
}

class TestTwo<T extends TestBase> {
    constructor(private testType: new () => T) {
    }

    getNew() : T {
        return new this.testType();
    }
}

//var test = new TestTwo<TestBase>(TestBase);
var test = new TestTwo<TestSub>(TestSub);

var example = test.getNew();
example.hi();

As it seems impossible to filter the XPath message data (it isn't in the XML to filter), you can also use powershell to search:

Get-WinEvent -LogName System | Where-Object {$_.Message -like "*recycle*"}

From this, I can see that the event Id for recycling seems to be 5074, so you can filter on this as well. I hope this helps someone as this information seemed to take a lot longer than expected to work out.

This along with @BlackHawkDesign comment should help you find what you need.

I had the same issue. Maybe interesting to mention is that you have to configure in which cases the app pool recycle event is logged. By default it's in a couple of cases, not all of them. You can do that in IIS > app pools > select the app pool > advanced settings > expand generate recycle event log entry – BlackHawkDesign Jan 14 '15 at 10:00

There is a new index method called difference. It returns the original columns, with the columns passed as argument removed.

Here, the result is used to remove columns B and D from df:

df2 = df[df.columns.difference(['B', 'D'])]

Note that it's a set-based method, so duplicate column names will cause issues, and the column order may be changed.

Advantage over drop: you don't create a copy of the entire dataframe when you only need the list of columns. For instance, in order to drop duplicates on a subset of columns:

# may create a copy of the dataframe
subset = df.drop(['B', 'D'], axis=1).columns

# does not create a copy the dataframe
subset = df.columns.difference(['B', 'D'])

df = df.drop_duplicates(subset=subset)

If you are uploading your files through GIT from your local machine then you can use the same command you are using in your local machine while you are connected to your live server using BASH or something like.You can use this as like you use locally.

php artisan cache:clear

php artisan route:cache

It should work.

Expanding on zoul's answer:

If you want to setup Vim to use specific settings when editing a particular filetype, you'll want to use autocommands:

autocmd Filetype css setlocal tabstop=4

This will make it so that tabs are displayed as 4 spaces. Setting expandtab will cause Vim to actually insert spaces (the number of them being controlled by tabstop) when you press tab; you might want to use softtabstop to make backspace work properly (that is, reduce indentation when that's what would happen should tabs be used, rather than always delete one char at a time).

To make a fully educated decision as to how to set things up, you'll need to read Vim docs on tabstop, shiftwidth, softtabstop and expandtab. The most interesting bit is found under expandtab (:help 'expandtab):

There are four main ways to use tabs in Vim:

1. Always keep 'tabstop' at 8, set 'softtabstop' and 'shiftwidth' to 4 (or 3 or whatever you prefer) and use 'noexpandtab'. Then Vim will use a mix of tabs and spaces, but typing and will behave like a tab appears every 4 (or 3) characters.

2. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use 'expandtab'. This way you will always insert spaces. The formatting will never be messed up when 'tabstop' is changed.

3. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use a |modeline| to set these values when editing the file again. Only works when using Vim to edit the file.

4. Always set 'tabstop' and 'shiftwidth' to the same value, and 'noexpandtab'. This should then work (for initial indents only) for any tabstop setting that people use. It might be nice to have tabs after the first non-blank inserted as spaces if you do this though. Otherwise aligned comments will be wrong when 'tabstop' is changed.

Regarding David Elizondo's answer, this can give false positives. It also does not give zeroes where the values don't match.

Code

DECLARE @t1 TABLE (
    ColID   int     IDENTITY,
    Col2    int
)

DECLARE @t2 TABLE (
    ColID   int     IDENTITY,
    Col2    int
)

INSERT INTO @t1 (Col2) VALUES (123)
INSERT INTO @t1 (Col2) VALUES (234)
INSERT INTO @t1 (Col2) VALUES (456)
INSERT INTO @t1 (Col2) VALUES (1)

INSERT INTO @t2 (Col2) VALUES (123)
INSERT INTO @t2 (Col2) VALUES (345)
INSERT INTO @t2 (Col2) VALUES (456)
INSERT INTO @t2 (Col2) VALUES (2)

SELECT
    t1.Col2 AS t1Col2,
    t2.Col2 AS t2Col2,
    ISNULL(NULLIF(t1.Col2, t2.Col2), 1) AS MyDesiredResult
FROM @t1 AS t1
JOIN @t2 AS t2 ON t1.ColID = t2.ColID

Results

     t1Col2      t2Col2 MyDesiredResult
----------- ----------- ---------------
        123         123               1
        234         345             234 <- Not a zero

Make sure your java\bin directory is in your path statement before the windows\system32 directory. The SDK Manager uses java and it was finding the one in the system32 folder.

In a CMD window, you can run 'where java'. Don't forget to restart your CMD after changing the path variable for checking.

I had this identical problem, I was using django-rest-knox for authentication tokens. It turns out that nothing was wrong with my fetch method which looked like this:

...
    let headers = {"Content-Type": "application/json"};
    if (token) {
      headers["Authorization"] = `Token ${token}`;
    }
    return fetch("/api/instruments/", {headers,})
      .then(res => {
...

I was running apache.

What solved this problem for me was changing WSGIPassAuthorization to 'On' in wsgi.conf.

I had a Django app deployed on AWS EC2, and I used Elastic Beanstalk to manage my application, so in the django.config, I did this:

container_commands:
  01wsgipass:
    command: 'echo "WSGIPassAuthorization On" >> ../wsgi.conf'

Simple is better, one variable, one function :)

const counts = arr.reduce((acc, value) => ({
   ...acc,
   [value]: (acc[value] || 0) + 1
}), {});

Yes, you can download the IP address ranges by country from https://lite.ip2location.com/ip-address-ranges-by-country

You can see that each country has multiple ranges and changes frequently.

To print the combined string using

Println("\(string1)\(string2)")

or String3 stores the output of combination of 2 strings

let strin3 = "\(string1)\(string2)"

from operator import itemgetter
from itertools import groupby

lki = [["A",0], ["B",1], ["C",0], ["D",2], ["E",2]]
lki.sort(key=itemgetter(1))

glo = [[x for x,y in g]
       for k,g in  groupby(lki,key=itemgetter(1))]

print glo

.

EDIT

Another solution that needs no import , is more readable, keeps the orders, and is 22 % shorter than the preceding one:

oldlist = [["A",0], ["B",1], ["C",0], ["D",2], ["E",2]]

newlist, dicpos = [],{}
for val,k in oldlist:
    if k in dicpos:
        newlist[dicpos[k]].extend(val)
    else:
        newlist.append([val])
        dicpos[k] = len(dicpos)

print newlist

There many cases where script Manager may give problem like that. you Try This First add Script Manager in appropriate Placeholder or any place Holder which appears before the content in which Ajax Control is used.

1. We need to add ScriptManager while using any AJAX Control not only update Panel. <asp:ScriptManager ID="ScriptManger1" runat="Server" />

2. If you are using Latest Ajax Control Toolkit (I am not sure about version 4.0 or 4.5) you need to use that Particular ToolkitScriptManager and not ScriptManager from default Ajax Extensions.

3. You can use only one ScriptManager or ToolKitScriptManager on page, If you have added it on Master Page you no need to add it again on Web Page.

4. The problem mentioned here may because of ContentPlaceHolder Please Check how many content place holders you have on your master page. Lets take an example if you have 2 content Placeholders "Head" and "ContentPlaceHolder1" on Master Page and ContentPlaceHolder1 is your Content Page.please check below code I added here my ScriptManager on Second Placeholder just below there is update panel.

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <asp:ContentPlaceHolder id="head" runat="server">
    </asp:ContentPlaceHolder>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ContentPlaceHolder id="MainContent" runat="server">
        <asp:ScriptManager ID="ScriptManger1" runat="Server" />
          <asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
    </ContentTemplate>
</asp:UpdatePanel>
        </asp:ContentPlaceHolder>
    </div>
    </form>
</body>
</html> 

Most of us make mistake while designing web form when we choose masterpage by default on web page there are equal number of placeholders as of MasterPage.

<%@ Page Title="" Language="C#" MasterPageFile="~/Master Pages/Home.master" AutoEventWireup="true" CodeFile="frmCompanyLogin.aspx.cs" Inherits="Authentication_frmCompanyLogin" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">
</asp:Content>

We no need to remove any PlaceHolder it is guiding structure but you must have to add the web form Contents in Same PlaceHolder where you added your ScriptManager(on Master Page) or add Script Manager in appropriate Placeholder or any place Holder which appears before the content in which Ajax Control is used.

Pandas Sorting 101

sort has been replaced in v0.20 by DataFrame.sort_values and DataFrame.sort_index. Aside from this, we also have argsort.

Here are some common use cases in sorting, and how to solve them using the sorting functions in the current API. First, the setup.

# Setup
np.random.seed(0)
df = pd.DataFrame({'A': list('accab'), 'B': np.random.choice(10, 5)})    
df                                                                                                                                        
   A  B
0  a  7
1  c  9
2  c  3
3  a  5
4  b  2

Sort by Single Column

For example, to sort df by column "A", use sort_values with a single column name:

df.sort_values(by='A')

   A  B
0  a  7
3  a  5
4  b  2
1  c  9
2  c  3

If you need a fresh RangeIndex, use DataFrame.reset_index.

Sort by Multiple Columns

For example, to sort by both col "A" and "B" in df, you can pass a list to sort_values:

df.sort_values(by=['A', 'B'])

   A  B
3  a  5
0  a  7
4  b  2
2  c  3
1  c  9

Sort By DataFrame Index

df2 = df.sample(frac=1)
df2

   A  B
1  c  9
0  a  7
2  c  3
3  a  5
4  b  2

You can do this using sort_index:

df2.sort_index()

   A  B
0  a  7
1  c  9
2  c  3
3  a  5
4  b  2

df.equals(df2)                                                                                                                            
# False
df.equals(df2.sort_index())                                                                                                               
# True

Here are some comparable methods with their performance:

%timeit df2.sort_index()                                                                                                                  
%timeit df2.iloc[df2.index.argsort()]                                                                                                     
%timeit df2.reindex(np.sort(df2.index))                                                                                                   

605 µs ± 13.6 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
610 µs ± 24.2 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
581 µs ± 7.63 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

Sort by List of Indices

For example,

idx = df2.index.argsort()
idx
# array([0, 7, 2, 3, 9, 4, 5, 6, 8, 1])

This "sorting" problem is actually a simple indexing problem. Just passing integer labels to iloc will do.

df.iloc[idx]

   A  B
1  c  9
0  a  7
2  c  3
3  a  5
4  b  2

EncryptionThe Purpose of encryption is to transform data in order to keep it secret E.g (Sending someone a secret text that they only should able to read,sending passwords through Internet).

Instead of focusing the usability the goal is to ensure the data send can be sent secretly and it can only seen by the user whom you sent.

It Encrypts the data into another format of transforming it into unique pattern it can be encrypt with the secret key and those users who having the secret key can able to see the message by reversible the process. E.g(AES,BLOWFISH,RSA)

The encryption may simply look like this FhQp6U4N28GITVGjdt37hZN

Hashing In technically we can say it as takes a arbitary input and produced a fixed length string.

Most important thing in these is you can't go from the output to the input.It produces the strong output that the given information has not been modified. The process is to take a input and hash it and then send with the sender's private key once the receiver received they can validate it with sender's public key.

If the hash is wrong and did't match with hash we can't see any of the information. E.g(MD5,SHA.....)

I assume you know how to get the DOM object for the <a> element (use document.getElementById or some other method).

To add any attribute, just use the setAttribute method on the DOM object:

a = document.getElementById(...);
a.setAttribute("href", "somelink url");

This is a problem where functional techniques shine. For example, the following F# solution is both clearer and less bug prone than the best imperative Java solution (and I work daily with both Java and F#).

[1;1;2;3;3;3] 
|> Seq.countBy id 
|> Seq.choose (fun (key,count) -> if count > 1 then Some(key) else None)

Of course, this question is about Java. So my suggestion is to adopt a library which brings functional features to Java. For example, it could be solved using my own library as follows (and there are several others out there worth looking at too):

Seq.of(1,1,2,3,3,3)
.groupBy(new Func1<Integer,Integer>() {
    public Integer call(Integer key) {
        return key;
    }
}).filter(new Predicate<Grouping<Integer,Integer>>() {
   public Boolean call(Grouping<Integer, Integer> grouping) {
        return grouping.getGrouping().count() > 1;
   }
}).map(new Func1<Grouping<Integer,Integer>,Integer>() {
    public Integer call(Grouping<Integer, Integer> grouping) {
        return grouping.getKey();
    }
});

Reproducible code is key to get help. However, there are many users that might be skeptical of pasting even a chunk of their data. For instance, they could be working with sensitive data or on an original data collected to use in a research paper. For any reason, I thought it would be nice to have a handy function for "deforming" my data before pasting it publicly. The anonymize function from the package SciencesPo is very silly, but for me it works nicely with dput function.

install.packages("SciencesPo")

dt <- data.frame(
    Z = sample(LETTERS,10),
    X = sample(1:10),
    Y = sample(c("yes", "no"), 10, replace = TRUE)
)

> dt
   Z  X   Y
1  D  8  no
2  T  1 yes
3  J  7  no
4  K  6  no
5  U  2  no
6  A 10 yes
7  Y  5  no
8  M  9 yes
9  X  4 yes
10 Z  3  no

Then I anonymize it:

> anonymize(dt)
     Z    X  Y
1   b2  2.5 c1
2   b6 -4.5 c2
3   b3  1.5 c1
4   b4  0.5 c1
5   b7 -3.5 c1
6   b1  4.5 c2
7   b9 -0.5 c1
8   b5  3.5 c2
9   b8 -1.5 c2
10 b10 -2.5 c1

One may also want to sample few variables instead of the whole data before apply anonymization and dput command.

    # sample two variables without replacement
> anonymize(sample.df(dt,5,vars=c("Y","X")))
   Y    X
1 a1 -0.4
2 a1  0.6
3 a2 -2.4
4 a1 -1.4
5 a2  3.6

This error was caused for me because of the path where my project was located. There was a blank space in one folder, for example,

Folder\Another Folder\MyAndroidProjects\...

Changing it to Folder\AnotherFolder\MyAndroidProjects\... and resynchronising Gradle resolved this for me.

use this when you want to convert list of struct type into string

struct MyStruct {
  var name : String
  var content : String
}

let myStructList = [MyStruct(name: "name1" , content: "content1") , MyStruct(name: "name2" , content: "content2")]

and covert your array like this way

let myString = myStructList.map({$0.name}).joined(separator: ",")

will produce ===> "name1,name2"

deleted the c#... here is the vb.net

<%=Html.ActionLink("Home", "Index", "Home", New With {.class = "tab"}, Nothing)%>

That's because itoa isn't a standard function. Try snprintf instead.

char str[LEN];
snprintf(str, LEN, "%d", 42);

It's likely that the download was corrupted if you are getting an error with the disk image. Go back to the downloads page at https://developers.google.com/appengine/downloads and look at the SHA1 checksum. Then, go to your Terminal app on your mac and run the following:

openssl sha1 [put the full path to the file here without brackets] 

For example:

openssl sha1 /Users/me/Desktop/myFile.dmg 

If you get a different value than the one on the Downloads page, you know your file is not properly downloaded and you should try again.

Creating a virtual environment for Jupyter Notebooks

A minimal Python install is

sudo apt install python3.7 python3.7-venv python3.7-minimal python3.7-distutils python3.7-dev python3.7-gdbm python3-gdbm-dbg python3-pip

Then you can create and use the environment

/usr/bin/python3.7 -m venv test
cd test
source test/bin/activate
pip install jupyter matplotlib seaborn numpy pandas scipy
# install other packages you need with pip/apt
jupyter notebook
deactivate

You can make a kernel for Jupyter with

ipython3 kernel install --user --name=test

you can use the following SQL statement to check the given column on table was indexed or not

select  a.table_schema, a.table_name, a.column_name, index_name
from    information_schema.columns a
join    information_schema.tables  b on a.table_schema  = b.table_schema and
                                    a.table_name = b.table_name and 
                                    b.table_type = 'BASE TABLE'
left join (
 select     concat(x.name, '/', y.name) full_path_schema, y.name index_name
 FROM   information_schema.INNODB_SYS_TABLES  as x
 JOIN   information_schema.INNODB_SYS_INDEXES as y on x.TABLE_ID = y.TABLE_ID
 WHERE  x.name = 'your_schema'
 and    y.name = 'your_column') d on concat(a.table_schema, '/', a.table_name, '/', a.column_name) = d.full_path_schema
where   a.table_schema = 'your_schema'
and     a.column_name  = 'your_column'
order by a.table_schema, a.table_name;

since the joins are against INNODB_SYS_*, so the match indexes only came from INNODB tables only

I had a similar issue that cropped up when using tight_layout for a very large grid of plots (more than 200 subplots) and rendering in a jupyter notebook. I made a quick solution that always places your suptitle at a certain distance above your top subplot:

import matplotlib.pyplot as plt

n_rows = 50
n_col = 4
fig, axs = plt.subplots(n_rows, n_cols)

#make plots ...

# define y position of suptitle to be ~20% of a row above the top row
y_title_pos = axs[0][0].get_position().get_points()[1][1]+(1/n_rows)*0.2
fig.suptitle('My Sup Title', y=y_title_pos)

For variably-sized subplots, you can still use this method to get the top of the topmost subplot, then manually define an additional amount to add to the suptitle.

From the api docs http://api.rubyonrails.org/classes/ActiveRecord/Callbacks.html Use the before_validation method in your model, it gives you the options of creating specific initialisation for create and update calls e.g. in this example (again code taken from the api docs example) the number field is initialised for a credit card. You can easily adapt this to set whatever values you want

class CreditCard < ActiveRecord::Base
  # Strip everything but digits, so the user can specify "555 234 34" or
  # "5552-3434" or both will mean "55523434"
  before_validation(:on => :create) do
    self.number = number.gsub(%r[^0-9]/, "") if attribute_present?("number")
  end
end

class Subscription < ActiveRecord::Base
  before_create :record_signup

  private
    def record_signup
      self.signed_up_on = Date.today
    end
end

class Firm < ActiveRecord::Base
  # Destroys the associated clients and people when the firm is destroyed
  before_destroy { |record| Person.destroy_all "firm_id = #{record.id}"   }
  before_destroy { |record| Client.destroy_all "client_of = #{record.id}" }
end

Surprised that his has not been suggested here

I use the GetSchemaTable method, which is exposed via the IDataReader interface.

This is actually the conventional use of the break statement. If the break statement wasn't nested in an if block the for loop could only ever execute one time.

MSDN lists this as their example for the break statement.

numpy provides a simple function to do the exact same thing: supposing you have a masked array 'a', calling numpy.ma.compress_rows(a) will delete the rows containing a masked value. I guess this is much faster this way...

You can get the path via fp.name. Example:

>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'

You might need os.path.basename if you want only the file name:

>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'

please don't try with the old cv module, use cv2:

import cv2

cv2.rectangle(img, (x1, y1), (x2, y2), (255,0,0), 2)


x1,y1 ------
|          |
|          |
|          |
--------x2,y2

[edit] to append the follow-up questions below:

cv2.imwrite("my.png",img)

cv2.imshow("lalala", img)
k = cv2.waitKey(0) # 0==wait forever

Here is the simplest example that has the key lines of code:

import numpy as np 
import matplotlib.pyplot as plt

H = np.array([[1, 2, 3, 4],
          [5, 6, 7, 8],
          [9, 10, 11, 12],
          [13, 14, 15, 16]])

plt.imshow(H, interpolation='none')
plt.show()

Just use resize: none

textarea {
   resize: none;
}

You can also decide to resize your textareas only horizontal or vertical, this way:

textarea { resize: vertical; }

textarea { resize: horizontal; }

Finally, resize: both enables the resize grabber.

I also had this issue with Visual Studio 2015, tried everything I could read about but in the end all that was left was a clean install. I used Microsofts tool VisualStudioUninstaller to get rid of every component.

https://github.com/Microsoft/VisualStudioUninstaller

Usage:

1. Extract TotalUninstaller.zip
2. Open an administrator command prompt.
3. Execute Setup.ForcedUninstall.exe
4. Type 'Y' to uninstall.

After reinstall everything worked normally again. I did not experience lag in every project but one was causing enough pain so I really had no choice.

Read about another command that you can also try but I know VisualStudioUninstaller works, at least it did for me.

D:\vs_ultimate.exe /uninstall /force

Where D: is the location of your installation media (mounted iso, etc).

As of 2014, here is a statement from a Microsoft representative (the Scripting Guy):

As much as we might hate to admit it, there are still no Windows PowerShell cmdlets from Microsoft that permit creating local user accounts or local user groups. We finally have a Desired State Configuration (DSC ) provider that can do this—but to date, no cmdlets.

This is what I use to display images from blob:

echo '<img src="data:image/jpeg;base64,'.base64_encode($image->load()) .'" />';

Try this

AppDomain.CurrentDomain.SetupInformation.ConfigurationFile

You can convert string to an integer value with the help of parse method.

Eg:

int val = Int32.parse(stringToBeParsed);
int x = Int32.parse(1234);

Did you use the webpack... if yes please install

angular2-template-loader

and put it

test: /\.ts$/,
   loaders: ['awesome-typescript-loader', 'angular2-template-loader']

In case you're wondering WHY they put a hidden field in with the same name as the checkbox the reason is as follows :

Comment from the sourcecode MVCBetaSource\MVC\src\MvcFutures\Mvc\ButtonsAndLinkExtensions.cs

Render an additional <input type="hidden".../> for checkboxes. This addresses scenarios where unchecked checkboxes are not sent in the request. Sending a hidden input makes it possible to know that the checkbox was present on the page when the request was submitted.

I guess behind the scenes they need to know this for binding to parameters on the controller action methods. You could then have a tri-state boolean I suppose (bound to a nullable bool parameter). I've not tried it but I'm hoping thats what they did.

Recursive function to reverse a string in place (no extra buffer, malloc).

Short, sexy code. Bad, bad stack usage.

#include <stdio.h>

/* Store the each value and move to next char going down
 * the stack. Assign value to start ptr and increment 
 * when coming back up the stack (return).
 * Neat code, horrible stack usage.
 *
 * val - value of current pointer.
 * s - start pointer
 * n - next char pointer in string.
 */
char *reverse_r(char val, char *s, char *n)
{
    if (*n)
        s = reverse_r(*n, s, n+1);
   *s = val;
   return s+1;
}

/*
 * expect the string to be passed as argv[1]
 */
int main(int argc, char *argv[])
{
    char *aString;

    if (argc < 2)
    {
        printf("Usage: RSIP <string>\n");
        return 0;
    }

    aString = argv[1];
    printf("String to reverse: %s\n", aString );

    reverse_r(*aString, aString, aString+1); 
    printf("Reversed String:   %s\n", aString );

    return 0;
}

You can access you website using your IP address and your cPanel username with ~ symbols. For Example: http://serverip/~cpusername like as https://xxx.xxx.xx.xx/~mohidul

This is my personal solution, based on the information here (this thread):

var Divs = new Array();    
var Elemns = document.getElementsByClassName("divisao");
    try {
        Divs = Elemns.prototype.slice.call(Elemns);
    } catch(e) {
        Divs = $A(Elemns);
    }

Where $A was described by Gareth Davis in his post:

function $A(iterable) {
  if (!iterable) return [];
  if ('toArray' in Object(iterable)) return iterable.toArray();
  var length = iterable.length || 0, results = new Array(length);
  while (length--) results[length] = iterable[length];
  return results;
}

If browser supports the best way, ok, otherwise will use the cross browser.

In 2019 it's easier to style your seekbar to your preferred color by changing your ProgressBar to this

<SeekBar
            android:id="@+id/seekBar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:progressTint="#36970f"
            android:thumbTint="#36970f"
            />

Styling your seekbar color programmatically try the following code

        seekBar.getProgressDrawable().setColorFilter(Color.RED, PorterDuff.Mode.SRC_IN);
        seekBar.getThumb().setColorFilter(Color.RED, PorterDuff.Mode.SRC_IN);

x86 is rather broad range of devices.

For totally generic x86 target, an assembly block with "rep movsd" could blast out zeros to memory 32-bits at time. Try to make sure the bulk of this work is DWORD aligned.

For chips with mmx, an assembly loop with movq could hit 64bits at a time.

You might be able to get a C/C++ compiler to use a 64-bit write with a pointer to a long long or _m64. Target must be 8 byte aligned for the best performance.

for chips with sse, movaps is fast, but only if the address is 16 byte aligned, so use a movsb until aligned, and then complete your clear with a loop of movaps

Win32 has "ZeroMemory()", but I forget if thats a macro to memset, or an actual 'good' implementation.

Why not use the Bootstrap predefined class input-block-level that does the job?

<a href="#" class="btn input-block-level">Full-Width Button</a> <!-- BS2 -->
<a href="#" class="btn form-control">Full-Width Button</a> <!-- BS3 -->

<!-- And let's join both for BS# :) -->
<a href="#" class="btn input-block-level form-control">Full-Width Button</a>

%3A and %2F are URL encoded characters. Use this java code to convert them back into : and /

String decoded = java.net.URLDecoder.decode(url, "UTF-8");

You can use the IF statement in a new cell to replace text, such as:

=IF(A4="C", "Other", A4)

This will check and see if cell value A4 is "C", and if it is, it replaces it with the text "Other"; otherwise, it uses the contents of cell A4.

EDIT

Assuming that the Employee_Count values are in B1-B10, you can use this:

=IF(B1=LARGE($B$1:$B$10, 10), "Other", B1)

This function doesn't even require the data to be sorted; the LARGE function will find the 10th largest number in the series, and then the rest of the formula will compare against that.

I think the selected answer is not correct, as the original question is "how to add a new validator after create the formControl".

As far as I know, that's not possible. The only thing you can do, is create the array of validators dynamicaly.

But what we miss is to have a function addValidator() to not override the validators already added to the formControl. If anybody has an answer for that requirement, would be nice to be posted here.

DECLARE @SQL varchar(max)=''

-- MyTable has fields fld1 & fld2

Select @SQL = @SQL + 'exec myproc ' + convert(varchar(10),fld1) + ',' 
                   + convert(varchar(10),fld2) + ';'
From MyTable

EXEC (@SQL)

Ok, so I would never put such code into production, but it does satisfy your requirements.

A more direct way would be:

myvar=$(mysql mydatabase -u $user -p$password -se "SELECT a, b, c FROM table_a")

Just use the length filter on the whole array. It works on more than just strings:

{{ notcount|length }}

You probably want git checkout master, or git checkout [branchname].

git revert makes a new commit

git revert simply creates a new commit that is the opposite of an existing commit.

It leaves the files in the same state as if the commit that has been reverted never existed. For example, consider the following simple example:

$ cd /tmp/example
$ git init
Initialized empty Git repository in /tmp/example/.git/
$ echo "Initial text" > README.md
$ git add README.md
$ git commit -m "initial commit"
[master (root-commit) 3f7522e] initial commit
 1 file changed, 1 insertion(+)
 create mode 100644 README.md
$ echo "bad update" > README.md 
$ git commit -am "bad update"
[master a1b9870] bad update
 1 file changed, 1 insertion(+), 1 deletion(-)

In this example the commit history has two commits and the last one is a mistake. Using git revert:

$ git revert HEAD
[master 1db4eeb] Revert "bad update"
 1 file changed, 1 insertion(+), 1 deletion(-)

There will be 3 commits in the log:

$ git log --oneline
1db4eeb Revert "bad update"
a1b9870 bad update
3f7522e initial commit

So there is a consistent history of what has happened, yet the files are as if the bad update never occured:

cat README.md 
Initial text

It doesn't matter where in the history the commit to be reverted is (in the above example, the last commit is reverted - any commit can be reverted).

Closing questions

do you have to do something else after?

A git revert is just another commit, so e.g. push to the remote so that other users can pull/fetch/merge the changes and you're done.

Do you have to commit the changes revert made or does revert directly commit to the repo?

git revert is a commit - there are no extra steps assuming reverting a single commit is what you wanted to do.

Obviously you'll need to push again and probably announce to the team.

Indeed - if the remote is in an unstable state - communicating to the rest of the team that they need to pull to get the fix (the reverting commit) would be the right thing to do :).

use sequenty.

sudo npm install sequenty

or

https://github.com/AndyShin/sequenty

very simple.

var sequenty = require('sequenty'); 

function f1(cb) // cb: callback by sequenty
{
  console.log("I'm f1");
  cb(); // please call this after finshed
}

function f2(cb)
{
  console.log("I'm f2");
  cb();
}

sequenty.run([f1, f2]);

also you can use a loop like this:

var f = [];
var queries = [ "select .. blah blah", "update blah blah", ...];

for (var i = 0; i < queries.length; i++)
{
  f[i] = function(cb, funcIndex) // sequenty gives you cb and funcIndex
  {
    db.query(queries[funcIndex], function(err, info)
    {
       cb(); // must be called
    });
  }
}

sequenty.run(f); // fire!

you have have strange characters in your heading # % -- or ,

This worked for me:

SELECT EXTRACT(YEAR FROM ASOFDATE) FROM PSASOFDATE;

So, because everyone is posting their solution and none was good for me, here is mine (tested on Chrome & Firefox).

table { height: 1px; } /* Will be ignored, don't worry. */
tr { height: 100%; }
td { height: 100%; }
td > div { height: 100%; }

Fiddle: https://jsfiddle.net/nh6g5fzv/

--

Edit: one thing you might want to note, if you want to apply a padding to the div in the td, you must add box-sizing: border-box; because of height: 100%.

Junit is included by default with Eclipse (at least the Java EE version I'm sure). You may just need to add the view to your perspective.

Yow can use querySelectorAll to select all the classes and loop through them to assign the eventListener. The if condition checks if it contains the class name.

const arrClass = document.querySelectorAll(".className");
for (let i of arrClass) {
  i.addEventListener("click", (e) => {
    if (e.target.classList.contains("className")) {
        console.log("Perfrom Action")
    }
  })
}

LIMIT limit OFFSET offset will work.

But you need a stable ORDER BY clause, or the values may be ordered differently for the next call (after any write on the table for instance).

SELECT *
FROM   msgtable
WHERE  cdate = '2012-07-18'
ORDER  BY msgtable_id  -- or whatever is stable 
LIMIT  10
OFFSET 50;  -- to skip to page 6

Use standard-conforming date style (ISO 8601 in my example), which works irregardless of your locale settings.

Paging will still shift if involved rows are inserted or deleted or changed in relevant columns. It has to.

To avoid that shift or for better performance with big tables use smarter paging strategies:

• Optimize query with OFFSET on large table

The next steps after resolving the conflicts manually are:-

1. git add .
2. git status (this will show you which commands are necessary to continue automatic merge procedure)
3. [command git suggests, e.g. git merge --continue, git cherry-pick --continue, git rebase --continue]

For me, the error message said I had too many simulator files open to build Swift. When I quit the simulator and built again, everything worked.

Arrays' constructors are different. Here are some ways to make an empty string array:

var arr = new string[0];
var arr = new string[]{};
var arr = Enumerable.Empty<string>().ToArray()

(sorry, on mobile)

This is what I tried for a right outer join [as per my requirement]:

m1 <- merge(x=companies, y=rounds2, by.x=companies$permalink, 
            by.y=rounds2$company_permalink, all.y=TRUE)
# Error in fix.by(by.x, x) : 'by' must specify uniquely valid columns
m1 <- merge(x=companies, y=rounds2, by.x=c("permalink"), 
            by.y=c("company_permalink"), all.y=TRUE)

This worked.

Here you can find the direct download link for Curl.exe

I was looking for the download process of Curl and every where they said copy curl.exe file in System32 but they haven't provided the direct link but after digging little more I Got it. so here it is enjoy, find curl.exe easily in bin folder just

unzip it and then go to bin folder there you get exe file

link to download curl generic

I did everything provided in the previous answers to this question, but still had the issue. I did have the update installed, but I ran the installer again, reapplying the update while SQL 2012 Installer was open on the screen where I could run the check again. After it finished, I ran the check again and it passed.

This will print all the subdirectories of the current directory:

print [name for name in os.listdir(".") if os.path.isdir(name)]

I'm not sure what you're doing with split("-"), but perhaps this code will help you find a solution?

If you want the full pathnames of the directories, use abspath:

print [os.path.abspath(name) for name in os.listdir(".") if os.path.isdir(name)]

Note that these pieces of code will only get the immediate subdirectories. If you want sub-sub-directories and so on, you should use walk as others have suggested.

SELECT
main.CustomerID,
f.Data AS FirstName,
m.Data AS MiddleName,
l.Data AS LastName,
d.Data AS Date
FROM table main
INNER JOIN table f on f.CustomerID = main.CustomerID
INNER JOIN table m on m.CustomerID = main.CustomerID
INNER JOIN table l on l.CustomerID = main.CustomerID
INNER JOIN table d on d.CustomerID = main.CustomerID
WHERE f.DBColumnName = 'FirstName' 
AND m.DBColumnName = 'MiddleName' 
AND l.DBColumnName = 'LastName' 
AND d.DBColumnName = 'Date' 

Edit: I have written this without an editor & have not run the SQL. I hope, you get the idea.

As pointed out in comments and other answers, the ISO C++ standard library did not add round() until ISO C++11, when this function was pulled in by reference to the ISO C99 standard math library.

For positive operands in [½, ub] round(x) == floor (x + 0.5), where ub is 2²³ for float when mapped to IEEE-754 (2008) binary32, and 2⁵² for double when it is mapped to IEEE-754 (2008) binary64. The numbers 23 and 52 correspond to the number of stored mantissa bits in these two floating-point formats. For positive operands in [+0, ½) round(x) == 0, and for positive operands in (ub, +8] round(x) == x. As the function is symmetric about the x-axis, negative arguments x can be handled according to round(-x) == -round(x).

This leads to the compact code below. It compiles into a reasonable number of machine instructions across various platforms. I observed the most compact code on GPUs, where my_roundf() requires about a dozen instructions. Depending on processor architecture and toolchain, this floating-point based approach could be either faster or slower than the integer-based implementation from newlib referenced in a different answer.

I tested my_roundf() exhaustively against the newlib roundf() implementation using Intel compiler version 13, with both /fp:strict and /fp:fast. I also checked that the newlib version matches the roundf() in the mathimf library of the Intel compiler. Exhaustive testing is not possible for double-precision round(), however the code is structurally identical to the single-precision implementation.

The original question addresses a specific narrow use case. For those who need more generic answers here are some examples:

Creating a new column using data from other columns

Given the dataframe below:

import pandas as pd
import numpy as np

df = pd.DataFrame([['dog', 'hound', 5],
                   ['cat', 'ragdoll', 1]],
                  columns=['animal', 'type', 'age'])

In[1]:
Out[1]:
  animal     type  age
----------------------
0    dog    hound    5
1    cat  ragdoll    1

Below we are adding a new description column as a concatenation of other columns by using the + operation which is overridden for series. Fancy string formatting, f-strings etc won't work here since the + applies to scalars and not 'primitive' values:

df['description'] = 'A ' + df.age.astype(str) + ' years old ' \
                    + df.type + ' ' + df.animal

In [2]: df
Out[2]:
  animal     type  age                description
-------------------------------------------------
0    dog    hound    5    A 5 years old hound dog
1    cat  ragdoll    1  A 1 years old ragdoll cat

We get 1 years for the cat (instead of 1 year) which we will be fixing below using conditionals.

Modifying an existing column with conditionals

Here we are replacing the original animal column with values from other columns, and using np.where to set a conditional substring based on the value of age:

# append 's' to 'age' if it's greater than 1
df.animal = df.animal + ", " + df.type + ", " + \
    df.age.astype(str) + " year" + np.where(df.age > 1, 's', '')

In [3]: df
Out[3]:
                 animal     type  age
-------------------------------------
0   dog, hound, 5 years    hound    5
1  cat, ragdoll, 1 year  ragdoll    1

Modifying multiple columns with conditionals

A more flexible approach is to call .apply() on an entire dataframe rather than on a single column:

def transform_row(r):
    r.animal = 'wild ' + r.type
    r.type = r.animal + ' creature'
    r.age = "{} year{}".format(r.age, r.age > 1 and 's' or '')
    return r

df.apply(transform_row, axis=1)

In[4]:
Out[4]:
         animal            type      age
----------------------------------------
0    wild hound    dog creature  5 years
1  wild ragdoll    cat creature   1 year

In the code above the transform_row(r) function takes a Series object representing a given row (indicated by axis=1, the default value of axis=0 will provide a Series object for each column). This simplifies processing since we can access the actual 'primitive' values in the row using the column names and have visibility of other cells in the given row/column.

You need the Character Entity References

< = &lt;

> = >

to_char(timestamp, 'YYYY-MM')

You say that the order is not "right", but I cannot see why it is wrong (at least until year 10000 comes around).

In your specific example you don't need to escape the equals - you only need to escape it if it's part of the key. The properties file format will treat all characters after the first unescaped equals as part of the value.

Just like it sounds like: if the path exists, but is a file and not a directory, isdir will return False. Meanwhile, exists will return True in both cases.

it is varchar right? So it then doesn't matter if you use 50 or 25, better be safe and use 50, that said I believe the longest I have seen is about 19 or so. Last names are longer

0 will get printed.

As in C++ true refers to 1 and false refers to 0.

In case, you want to print false instead of 0,then you have to sets the boolalpha format flag for the str stream.

When the boolalpha format flag is set, bool values are inserted/extracted by their textual representation: either true or false, instead of integral values.

#include <iostream>
int main()
{
  std::cout << std::boolalpha << false << std::endl;
}

output:

false

When using angularjs with express

On my example I was using angularjs with express doing the routing so using $routeParams would mess up with my routing. I used the following code to get what I was expecting:

const getParameters = (temp, path) => {
  const parameters = {};
  const tempParts = temp.split('/');
  const pathParts = path.split('/');
  for (let i = 0; i < tempParts.length; i++) {
    const element = tempParts[i];
    if(element.startsWith(':')) {
      const key = element.substring(1,element.length);
      parameters[key] = pathParts[i];
    }
  }
  return parameters;
};

This receives a URL template and the path of the given location. The I just call it with:

const params = getParameters('/:table/:id/visit/:place_id/on/:interval/something', $location.path()); 

Putting it all together my controller is:

.controller('TestController', ['$scope', function($scope, $window) {
  const getParameters = (temp, path) => {
    const parameters = {};
    const tempParts = temp.split('/');
    const pathParts = path.split('/');
    for (let i = 0; i < tempParts.length; i++) {
      const element = tempParts[i];
      if(element.startsWith(':')) {
        const key = element.substring(1,element.length);
        parameters[key] = pathParts[i];
      }
    }
    return parameters;
  };

const params = getParameters('/:table/:id/visit/:place_id/on/:interval/something', $window.location.pathname);
}]);

The result will be:

{ table: "users", id: "1", place_id: "43", interval: "week" }

Hope this helps someone out there!

In addition to the accepted answer I would like to give an answer that shows how to iterate directly over the Newtonsoft collections. It uses less code and I'm guessing its more efficient as it doesn't involve converting the collections.

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
//Parse the data
JObject my_obj = JsonConvert.DeserializeObject<JObject>(your_json);

foreach (KeyValuePair<string, JToken> sub_obj in (JObject)my_obj["ADDRESS_MAP"])
{
    Console.WriteLine(sub_obj.Key);
}

I started doing this myself because JsonConvert automatically deserializes nested objects as JToken (which are JObject, JValue, or JArray underneath I think).

I think the parsing works according to the following principles:

• Every object is abstracted as a JToken

• Cast to JObject where you expect a Dictionary

• Cast to JValue if the JToken represents a terminal node and is a value

• Cast to JArray if its an array

• JValue.Value gives you the .NET type you need

In ef core, you can change the migration that was created after add migration. And then do update-database. A sample has given below:

protected override void Up(MigrationBuilder migrationBuilder)
{
    migrationBuilder.RenameColumn(name: "Type", table: "Users", newName: "Discriminator", schema: "dbo");
}

protected override void Down(MigrationBuilder migrationBuilder)
{            
    migrationBuilder.RenameColumn(name: "Discriminator", table: "Users", newName: "Type", schema: "dbo");
}

Here example on plain JS:

document.querySelector('#myDiv').addEventListener('keyup', function (e) {_x000D_
  console.log(e.key)_x000D_
})

#myDiv {_x000D_
  outline: none;_x000D_
}

<div _x000D_
  id="myDiv"_x000D_
  tabindex="0"_x000D_
>_x000D_
  Press me and start typing_x000D_
</div>

In C99(ISO/IEC 9899:TC3) which seems absent from this discussion thus far the following steteents are made regarding order of evaluaiton.

[...]the order of evaluation of subexpressions and the order in which side effects take place are both unspecified. (Section 6.5 pp 67)

The order of evaluation of the operands is unspecified. If an attempt is made to modify the result of an assignment operator or to access it after the next sequence point, the behavior[sic] is undefined.(Section 6.5.16 pp 91)

I had this same problem and this link provided the solution for me:

http://www.holovaty.com/writing/cors-ie-cloudfront/

The short version of it is:

1. Edit S3 CORS config (my code sample didn't display properly)
   Note: This is already done in the original question
   Note: the code provided is not very secure, more info in the linked page.
2. Go to the "Behaviors" tab of your distribution and click to edit
3. Change "Forward Headers" from “None (Improves Caching)” to “Whitelist.”
4. Add “Origin” to the "Whitelist Headers" list
5. Save the changes

Your cloudfront distribution will update, which takes about 10 minutes. After that, all should be well, you can verify by checking that the CORS related error messages are gone from the browser.

You could use the INDIRECT function. This takes a string and converts it into a range

More info here

=INDIRECT("K"&A2)

But it's preferable to use INDEX as it is less volatile.

=INDEX(K:K,A2)

This returns a value or the reference to a value from within a table or range

More info here

Put either function into cell B2 and fill down.

I'd do it like this:

[id^="product"] {
  ...
}

Ideally, use a class. This is what classes are for:

<div id="product176" class="product"></div>
<div id="product177" class="product"></div>
<div id="product178" class="product"></div>

And now the selector becomes:

.product {
  ...
}

In my case, I was able to use a simple insert statement to bulk insert many rows into TABLE_A using just one column from TABLE_B and getting the other data elsewhere (sequence and a hardcoded value) :

INSERT INTO table_a (
    id,
    column_a,
    column_b
)
    SELECT
        table_a_seq.NEXTVAL,
        b.name,
        123
    FROM
        table_b b;

Result:

ID: NAME: CODE:
1, JOHN, 123
2, SAM, 123
3, JESS, 123

etc

This is the good way using formats:

const now = moment()
now.format("hh:mm:ss K") // 1:00:00 PM
now.format("HH:mm:ss") // 13:00:00

Red more about moment sring format

A switch works by comparing what is in switch() to every case.

switch (cnt) {
    case 1: ....
    case 2: ....
    case 3: ....
}

works like:

if (cnt == 1) ...
if (cnt == 2) ...
if (cnt == 3) ...

Therefore, you can't have any logic in the case statements.

switch (cnt) {
    case (cnt >= 10 && cnt <= 20): ...
}

works like

if (cnt == (cnt >= 10 && cnt <= 20)) ...

and that's just nonsense. :)

Use if () { } else if () { } else { } instead.

 grep -E -o "([0-9]{1,3}[\.]){3}[0-9]{1,3}"

The NSDictionary and NSMutableDictionary docs are probably your best bet. They even have some great examples on how to do various things, like...

...create an NSDictionary

NSArray *keys = [NSArray arrayWithObjects:@"key1", @"key2", nil];
NSArray *objects = [NSArray arrayWithObjects:@"value1", @"value2", nil];
NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:objects 
                                                       forKeys:keys];

...iterate over it

for (id key in dictionary) {
    NSLog(@"key: %@, value: %@", key, [dictionary objectForKey:key]);
}

...make it mutable

NSMutableDictionary *mutableDict = [dictionary mutableCopy];

Note: historic version before 2010: [[dictionary mutableCopy] autorelease]

...and alter it

[mutableDict setObject:@"value3" forKey:@"key3"];

...then store it to a file

[mutableDict writeToFile:@"path/to/file" atomically:YES];

...and read it back again

NSMutableDictionary *anotherDict = [NSMutableDictionary dictionaryWithContentsOfFile:@"path/to/file"];

...read a value

NSString *x = [anotherDict objectForKey:@"key1"];

...check if a key exists

if ( [anotherDict objectForKey:@"key999"] == nil ) NSLog(@"that key is not there");

...use scary futuristic syntax

From 2014 you can actually just type dict[@"key"] rather than [dict objectForKey:@"key"]

When passing parameters through the URL you're able to retrieve the values as GET parameters.

Use this:

$variable = $_GET['param_name'];

//Or as you have it
$ppc = $_GET['ppc'];

It is safer to check for the variable first though:

if (isset($_GET['ppc'])) {
  $ppc = $_GET['ppc'];
} else {
  //Handle the case where there is no parameter
}

Here's a bit of reading on GET/POST params you should look at: http://php.net/manual/en/reserved.variables.get.php

EDIT: I see this answer still gets a lot of traffic years after making it. Please read comments attached to this answer, especially input from @emc who details a WordPress function which accomplishes this goal securely.

See this Link

HTML

<div id="products"></div>

JS

var someone = {
"name":"Mahmoude Elghandour",
"price":"174 SR",
"desc":"WE Will BE WITH YOU"
 };
 var name = $("<div/>",{"text":someone.name,"class":"name"
});

var price = $("<div/>",{"text":someone.price,"class":"price"});
var desc = $("<div />", {   
"text": someone.desc,
"class": "desc"
});
$("#products").fadeIn(1500);
$("#products").append(name).append(price).append(desc);

You can also use unshift() to prepend to a list

Use Arrays.asList() to wrap the array in a List<String>, which does have a contains() method:

Arrays.asList(dan).contains(say.getText())

main()
{
  int i = 247593;
  char str[10];

  sprintf(str, "%d", i);
// Now str contains the integer as characters
}

Hope it will be helpful to you.

There can be multiple root causes for this exception. For me, my mockMvc wasn't getting auto-configured. I solved this exception by using @WebMvcTest(MyController.class) at the class level. This annotation will disable full auto-configuration and instead apply only configuration relevant to MVC tests.

An alternative to this is, If you are looking to load your full application configuration and use MockMVC, you should consider @SpringBootTest combined with @AutoConfigureMockMvc rather than @WebMvcTest

A branch is just a reference to a commit. Until you commit anything to the repository, you don't have any branches. You can see this in a non-bare repository as well.

$ mkdir repo
$ cd repo
$ git init

$ git branch
$ touch foo
$ git add foo
$ git commit -m "new file"
1 file changed, 0 insertions(+), 0 deletions(-)

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

I'm unsure of the context on why this was needed, so this may not return enough information for you but this is what I was able to do:

if(typeof(ModelName).GetProperty("Name of Property") != null)
{
//whatevver you were wanting to do.
}

In my case I'm running through properties from a form submission and also have default values to use if the entry is left blank - so I needed to know if the there was a value to use - I prefixed all my default values in the model with Default so all I needed to do is check if there was a property that started with that.

Extending adam-rosenfield's solution, i think the following will work for multithreaded single producer - single consumer scenario.

int cb_push_back(circular_buffer *cb, const void *item)
{
  void *new_head = (char *)cb->head + cb->sz;
  if (new_head == cb>buffer_end) {
      new_head = cb->buffer;
  }
  if (new_head == cb->tail) {
    return 1;
  }
  memcpy(cb->head, item, cb->sz);
  cb->head = new_head;
  return 0;
}

int cb_pop_front(circular_buffer *cb, void *item)
{
  void *new_tail = cb->tail + cb->sz;
  if (cb->head == cb->tail) {
    return 1;
  }
  memcpy(item, cb->tail, cb->sz);
  if (new_tail == cb->buffer_end) {
    new_tail = cb->buffer;
  }
  cb->tail = new_tail;
  return 0;
}

InputStream raw = context.getAssets().open("filename.ext");

Reader is = new BufferedReader(new InputStreamReader(raw, "UTF8"));

An another possible case is make sure that you have installed WCF Activation feature. Go to Server Manager > Features > Add Features

Here's an answer that works with codepoints outside of the Basic Multilingual Plane (Java 8+).

Using streams:

public String method(String str) {
    return str.codePoints()
            .limit(str.codePoints().count() - 1)
            .mapToObj(i->new String(Character.toChars(i)))
            .collect(Collectors.joining());
}

More efficient maybe:

public String method(String str) {
    return str.isEmpty()? "": str.substring(0, str.length() - Character.charCount(str.codePointBefore(str.length())));
}

I know this question is too old, but still, I think this approach would be cleaner:

cat = $.URLDecode(cat);
$('#cbCategory option:contains("' + cat + '")').prop('selected', true);

In this case you wont need to go over the entire options with each(). Although by that time prop() didn't exist so for older versions of jQuery use attr().

UPDATE

You have to be certain when using contains because you can find multiple options, in case of the string inside cat matches a substring of a different option than the one you intend to match.

Then you should use:

cat = $.URLDecode(cat);
$('#cbCategory option')
    .filter(function(index) { return $(this).text() === cat; })
    .prop('selected', true);

Use Escape sequence.

\"Hello\"

This will print "Hello".

Try something like

SELECT 'rupesh''s' + 'malviya'

To rollback the last migration you can do:

rake db:rollback

If you want to rollback a specific migration with a version you should do:

rake db:migrate:down VERSION=YOUR_MIGRATION_VERSION

If the migration file you want to rollback was called db/migrate/20141201122027_create_some_table.rb, then the VERSION for that migration is 20141201122027, which is the timestamp of when that migration was created, and the command to roll back that migration would be:

rake db:migrate:down VERSION=20141201122027

To only modify the title's font (and not the font of the axis) I used this:

import matplotlib.pyplot as plt
fig = plt.Figure()
ax = fig.add_subplot(111)
ax.set_title('My Title', fontdict={'fontsize': 8, 'fontweight': 'medium'})

The fontdict accepts all kwargs from matplotlib.text.Text.

To delete all directories with the name foo, run:

find -type d -name foo -a -prune -exec rm -rf {} \;

The other answers are missing an important thing: the -prune option. Without -prune, GNU find will delete the directory with the matching name and then try to recurse into it to find more directories that match. The -prune option tells it to not recurse into a directory that matched the conditions.

Just another variation:

    <body>
    <button name="redirect" onClick="redirect()">

    <script type="text/javascript">
    function redirect()
    {
    var url = "http://www.(url).com";
    window.location(url);
    }
    </script>

You need to construct a date string. You're using / or - operators which do MATH/numeric operations on the numeric return values of DATEPART. Then DATENAME is taking that numeric value and interpreting it as a date.

You need to convert it to a string. For example:

SELECT (
  DATENAME(dw, 
  CAST(DATEPART(m, GETDATE()) AS VARCHAR) 
  + '/' 
  + CAST(DATEPART(d, myDateCol1) AS VARCHAR) 
  + '/' 
  + CAST(DATEPART(yy, getdate()) AS VARCHAR))
  )

df = df.sort_index()

Note:

• sort has been deprecated, replaced by sort_index for this scenario
• preferable not to use inplace as it is usually harder to read and prevents chaining. See explanation in answer here: Pandas: peculiar performance drop for inplace rename after dropna

Execute the code below to update n number of rows, where Parent ID is the id you want to get the data from and Child ids are the ids u need to be updated so it's just u need to add the parent id and child ids to update all the rows u need using a small script.

    UPDATE [Table]
 SET couloumn1= (select couloumn1 FROM Table WHERE IDCouloumn = [PArent ID]),
     couloumn2= (select couloumn2 FROM Table WHERE IDCouloumn = [PArent ID]),
     couloumn3= (select couloumn3 FROM Table WHERE IDCouloumn = [PArent ID]),
     couloumn4= (select couloumn4 FROM Table WHERE IDCouloumn = [PArent ID]),
 WHERE IDCouloumn IN ([List of child Ids])

It is a generic type parameter, see Generics documentation.

T is not a reserved keyword. T, or any given name, means a type parameter. Check the following method (just as a simple example).

T GetDefault<T>()
{
    return default(T);
}

Note that the return type is T. With this method you can get the default value of any type by calling the method as:

GetDefault<int>(); // 0
GetDefault<string>(); // null
GetDefault<DateTime>(); // 01/01/0001 00:00:00
GetDefault<TimeSpan>(); // 00:00:00

.NET uses generics in collections, ... example:

List<int> integerList = new List<int>();

This way you will have a list that only accepts integers, because the class is instancited with the type T, in this case int, and the method that add elements is written as:

public class List<T> : ...
{
    public void Add(T item);
}

Some more information about generics.

You can limit the scope of the type T.

The following example only allows you to invoke the method with types that are classes:

void Foo<T>(T item) where T: class
{
}

The following example only allows you to invoke the method with types that are Circle or inherit from it.

void Foo<T>(T item) where T: Circle
{
}

And there is new() that says you can create an instance of T if it has a parameterless constructor. In the following example T will be treated as Circle, you get intellisense...

void Foo<T>(T item) where T: Circle, new()
{
    T newCircle = new T();
}

As T is a type parameter, you can get the object Type from it. With the Type you can use reflection...

void Foo<T>(T item) where T: class
{
    Type type = typeof(T);
}

As a more complex example, check the signature of ToDictionary or any other Linq method.

public static Dictionary<TKey, TSource> ToDictionary<TSource, TKey>(this IEnumerable<TSource> source, Func<TSource, TKey> keySelector);

There isn't a T, however there is TKey and TSource. It is recommended that you always name type parameters with the prefix T as shown above.

You could name TSomethingFoo if you want to.

Try:

count(a/b[.='tsr']/preceding-sibling::*)+1.

Using this, you can grab any item that has a specific value or label that you are looking for. This can be used to determine if an element has a label, style, value, etc. A common way to do this is to loop through the items in the drop down until you find the one that you want and select it. In C#

int items = driver.FindElement(By.XPath("//path_to_drop_Down")).Count(); 
for(int i = 1; i <= items; i++)
{
    string value = driver.FindElement(By.XPath("//path_to_drop_Down/option["+i+"]")).GetAttribute("Value1");
    if(value.Conatains("Label_I_am_Looking_for"))
    {
        driver.FindElement(By.XPath("//path_to_drop_Down/option["+i+"]")).Click(); 
        //Clicked on the index of the that has your label / value
    }
}

You are using

$ curl -s -XPOST localhost:9200/_bulk --data-binary @requests

If 'requests' is a json file then you have to change this to

$ curl -s -XPOST localhost:9200/_bulk --data-binary @requests.json

Now before this, if your json file is not indexed, you have to insert an index line before each line inside the json file. You can do this with JQ. Refer below link: http://kevinmarsh.com/2014/10/23/using-jq-to-import-json-into-elasticsearch.html

Go to elasticsearch tutorials (example the shakespeare tutorial) and download the json file sample used and have a look at it. In front of each json object (each individual line) there is an index line. This is what you are looking for after using the jq command. This format is mandatory to use the bulk API, plain json files wont work.

You can use strptime in the datetime package of Python:

>>> import datetime
>>> datetime.datetime.strptime('24052010', "%d%m%Y").date()
datetime.date(2010, 5, 24)

Here is an example:

List<String> names;
names.add("toto");
names.add("Lala");
names.add("papa");
int index = names.indexOf("papa"); // index = 2

It sounds like you might want just a bar graph:

• http://matplotlib.sourceforge.net/examples/pylab_examples/barchart_demo.html

Alternatively, you can use subplots.

Examples to clarify the important issue in accepted answer's comments

I didn't understand it until I played around with it myself, so I figured there would be others who were confused as well. Say you are working on the user whose id == 6 and whose no_of_logins == 30 when you start.

# 1 (bad)
user.no_of_logins += 1
# result: UPDATE user SET no_of_logins = 31 WHERE user.id = 6

# 2 (bad)
user.no_of_logins = user.no_of_logins + 1
# result: UPDATE user SET no_of_logins = 31 WHERE user.id = 6

# 3 (bad)
setattr(user, 'no_of_logins', user.no_of_logins + 1)
# result: UPDATE user SET no_of_logins = 31 WHERE user.id = 6

# 4 (ok)
user.no_of_logins = User.no_of_logins + 1
# result: UPDATE user SET no_of_logins = no_of_logins + 1 WHERE user.id = 6

# 5 (ok)
setattr(user, 'no_of_logins', User.no_of_logins + 1)
# result: UPDATE user SET no_of_logins = no_of_logins + 1 WHERE user.id = 6

The point

By referencing the class instead of the instance, you can get SQLAlchemy to be smarter about incrementing, getting it to happen on the database side instead of the Python side. Doing it within the database is better since it's less vulnerable to data corruption (e.g. two clients attempt to increment at the same time with a net result of only one increment instead of two). I assume it's possible to do the incrementing in Python if you set locks or bump up the isolation level, but why bother if you don't have to?

A caveat

If you are going to increment twice via code that produces SQL like SET no_of_logins = no_of_logins + 1, then you will need to commit or at least flush in between increments, or else you will only get one increment in total:

# 6 (bad)
user.no_of_logins = User.no_of_logins + 1
user.no_of_logins = User.no_of_logins + 1
session.commit()
# result: UPDATE user SET no_of_logins = no_of_logins + 1 WHERE user.id = 6

# 7 (ok)
user.no_of_logins = User.no_of_logins + 1
session.flush()
# result: UPDATE user SET no_of_logins = no_of_logins + 1 WHERE user.id = 6
user.no_of_logins = User.no_of_logins + 1
session.commit()
# result: UPDATE user SET no_of_logins = no_of_logins + 1 WHERE user.id = 6

In case someone want's to do this with a cronjob, please keep in mind that this:

find .session/ -atime +7  -exec rm {} \;

is really slow, when having a lot of files.

Consider using this instead:

find .session/ -atime +7 | xargs -r rm

In Case you have spaces in you file names use this:

find .session/ -atime +7 -print0 | xargs -0 -r rm

xargs will fill up the commandline with files to be deleted, then run the rm command a lot lesser than -exec rm {} \;, which will call the rm command for each file.

Just my two cents

git reset --hard
git clean -fd

This worked for me - clean showed all the files it deleted too. If it tells you you'll lose changes, you need to stash.

To fix the overlap, you only need modify the .navbar-toggle in your own css styles

df.columnname[1].split('.', 1)

This will split data with the first occurrence of '.' in the string or data frame column value.

Load testing your API by using just ab is not enough. However, I think it's a great tool to give you a basic idea how your site is performant.

If you want to use the ab command in to test multiple API endpoints, with different data, all at the same time in background, you need to use "nohup" command. It runs any command even when you close the terminal.

I wrote a simple script that automates the whole process, feel free to use it: http://blog.ikvasnica.com/entry/load-test-multiple-api-endpoints-concurrently-use-this-simple-shell-script

There are multiple solutions provided for this one. I checked the first one and after that wrote my own. Posting it here if it helps anyone:

Mode <- function(x){
  y <- data.frame(table(x))
  y[y$Freq == max(y$Freq),1]
}

Lets test it with a few example. I am taking the iris data set. Lets test with numeric data

> Mode(iris$Sepal.Length)
[1] 5

which you can verify is correct.

Now the only non numeric field in the iris dataset(Species) does not have a mode. Let's test with our own example

> test <- c("red","red","green","blue","red")
> Mode(test)
[1] red

EDIT

As mentioned in the comments, user might want to preserve the input type. In which case the mode function can be modified to:

Mode <- function(x){
  y <- data.frame(table(x))
  z <- y[y$Freq == max(y$Freq),1]
  as(as.character(z),class(x))
}

The last line of the function simply coerces the final mode value to the type of the original input.

Java does both compilation and interpretation,

In Java, programs are not compiled into executable files; they are compiled into bytecode (as discussed earlier), which the JVM (Java Virtual Machine) then interprets / executes at runtime. Java source code is compiled into bytecode when we use the javac compiler. The bytecode gets saved on the disk with the file extension .class.

When the program is to be run, the bytecode is converted the bytecode may be converted, using the just-in-time (JIT) compiler. The result is machine code which is then fed to the memory and is executed.

Javac is the Java Compiler which Compiles Java code into Bytecode. JVM is Java Virtual Machine which Runs/ Interprets/ translates Bytecode into Native Machine Code. In Java though it is considered as an interpreted language, It may use JIT (Just-in-Time) compilation when the bytecode is in the JVM. The JIT compiler reads the bytecodes in many sections (or in full, rarely) and compiles them dynamically into machine code so the program can run faster, and then cached and reused later without needing to be recompiled. So JIT compilation combines the speed of compiled code with the flexibility of interpretation.

An interpreted language is a type of programming language for which most of its implementations execute instructions directly and freely, without previously compiling a program into machine-language instructions. The interpreter executes the program directly, translating each statement into a sequence of one or more subroutines already compiled into machine code.

A compiled language is a programming language whose implementations are typically compilers (translators that generate machine code from source code), and not interpreters (step-by-step executors of source code, where no pre-runtime translation takes place)

In modern programming language implementations like in Java, it is increasingly popular for a platform to provide both options.

None of the above helped me, but futzing with the user seemed like it had promise. For my config using 'ubuntu' was right.....

ssh -i [full path to keypair file] ubuntu@[EC2 instance hostname or IP address]

Here's your example in the "one" line.

this.$OuterDiv = $('<div></div>')
    .hide()
    .append($('<table></table>')
        .attr({ cellSpacing : 0 })
        .addClass("text")
    )
;

Update: I thought I'd update this post since it still gets quite a bit of traffic. In the comments below there's some discussion about $("<div>") vs $("<div></div>") vs $(document.createElement('div')) as a way of creating new elements, and which is "best".

I put together a small benchmark, and here are roughly the results of repeating the above options 100,000 times:

jQuery 1.4, 1.5, 1.6

               Chrome 11  Firefox 4   IE9
<div>            440ms      640ms    460ms
<div></div>      420ms      650ms    480ms
createElement    100ms      180ms    300ms

jQuery 1.3

                Chrome 11
<div>             770ms
<div></div>      3800ms
createElement     100ms

jQuery 1.2

                Chrome 11
<div>            3500ms
<div></div>      3500ms
createElement     100ms

I think it's no big surprise, but document.createElement is the fastest method. Of course, before you go off and start refactoring your entire codebase, remember that the differences we're talking about here (in all but the archaic versions of jQuery) equate to about an extra 3 milliseconds per thousand elements.

Update 2

Updated for jQuery 1.7.2 and put the benchmark on JSBen.ch which is probably a bit more scientific than my primitive benchmarks, plus it can be crowdsourced now!

This answer will be for swift dictionary w/ String keys. Like this one below.

let dict: [String: Int] = ["hey": 1, "yo": 2, "sup": 3, "hello": 4, "whassup": 5]

Here's the extension I'll use.

extension Dictionary {
  func allKeys() -> [String] {
    guard self.keys.first is String else {
      debugPrint("This function will not return other hashable types. (Only strings)")
      return []
    }
    return self.flatMap { (anEntry) -> String? in
                          guard let temp = anEntry.key as? String else { return nil }
                          return temp }
  }
}

And I'll get all the keys later using this.

let componentsArray = dict.allKeys()

Morgan should not be used to log in the way you're describing. Morgan was built to do logging in the way that servers like Apache and Nginx log to the error_log or access_log. For reference, this is how you use morgan:

var express     = require('express'),
    app         = express(),
    morgan      = require('morgan'); // Require morgan before use

// You can set morgan to log differently depending on your environment
if (app.get('env') == 'production') {
  app.use(morgan('common', { skip: function(req, res) { return res.statusCode < 400 }, stream: __dirname + '/../morgan.log' }));
} else {
  app.use(morgan('dev'));
}

Note the production line where you see morgan called with an options hash {skip: ..., stream: __dirname + '/../morgan.log'}

The stream property of that object determines where the logger outputs. By default it's STDOUT (your console, just like you want) but it'll only log request data. It isn't going to do what console.log() does.

If you want to inspect things on the fly use the built in util library:

var util = require('util');
console.log(util.inspect(anyObject)); // Will give you more details than console.log

So the answer to your question is that you're asking the wrong question. But if you still want to use Morgan for logging requests, there you go.

If you are using RxJS 6.0.0:

import { from } from 'rxjs';
const observable = from(promise);

You can easily switch back to bash by using command "bye"

In mysql extended version, <> gives out error. You are using mysql_query Eventually, you have to use extended version of my mysql. Old will be replaced in future browser. Rather use something like

$con = mysqli_connect("host", "username", "password", "databaseName");

mysqli_query($con, "select orderid != 650");

Starting from Java 7 (or Android API Level 21 = 5.0+) you could directly use ThreadLocalRandom.current().nextLong(n) (for 0 = x < n) and ThreadLocalRandom.current().nextLong(m, n) (for m = x < n). See @Alex's answer for detail.

If you are stuck with Java 6 (or Android 4.x) you need to use an external library (e.g. org.apache.commons.math3.random.RandomDataGenerator.getRandomGenerator().nextLong(0, n-1), see @mawaldne's answer), or implement your own nextLong(n).

According to https://docs.oracle.com/javase/1.5.0/docs/api/java/util/Random.html nextInt is implemented as

 public int nextInt(int n) {
     if (n<=0)
                throw new IllegalArgumentException("n must be positive");

     if ((n & -n) == n)  // i.e., n is a power of 2
         return (int)((n * (long)next(31)) >> 31);

     int bits, val;
     do {
         bits = next(31);
         val = bits % n;
     } while(bits - val + (n-1) < 0);
     return val;
 }

So we may modify this to perform nextLong:

long nextLong(Random rng, long n) {
   // error checking and 2^x checking removed for simplicity.
   long bits, val;
   do {
      bits = (rng.nextLong() << 1) >>> 1;
      val = bits % n;
   } while (bits-val+(n-1) < 0L);
   return val;
}

You may have several php.ini files, one for CLI and one for apache. Run php --ini to see where the CLI ini location is.

Another way using regular expressions

int length = text.replaceAll("[^ ]", "").length();

What you could do is use the 'style' attribute to add the background image to the element, that way you will still be calling the image in the HTML but you will still be able to use the background-size: cover css behaviour:

HTML:

    <div class="image-div" style="background-image:url(yourimage.jpg)">
    </div>

CSS:

    .image-div{
    background-size: cover;
    }

This is how I add the background-size: cover behaviour to elements that I need to dynamically load into HTML. You can then use awesome css classes like background-position: center. boom

Try git config core.fileMode false

From the git config man page:

core.fileMode

If false, the executable bit differences between the index and the working copy are ignored; useful on broken filesystems like FAT. See git-update-index(1).

The default is true, except git-clone(1) or git-init(1) will probe and set core.fileMode false if appropriate when the repository is created.

var dt = new Date();

dt.getFullYear() + "/" + (dt.getMonth() + 1) + "/" + dt.getDate();

Since month index are 0 based you have to increment it by 1.

Edit

For a complete list of date object functions see

Date

getMonth()

Returns the month (0-11) in the specified date according to local time.

getUTCMonth()

Returns the month (0-11) in the specified date according to universal time.

Creating firewall rules

Please review the firewall rule components [1] if you are unfamiliar with firewall rules in GCP. Firewall rules are defined at the network level, and only apply to the network where they are created; however, the name you choose for each of them must be unique to the project.

For Cloud Console:

1. Go to the Firewall rules page in the Google Cloud Platform Console.
2. Click Create firewall rule.
3. Enter a Name for the firewall rule. This name must be unique for the project.
4. Specify the Network where the firewall rule will be implemented.
5. Specify the Priority of the rule. The lower the number, the higher the priority.
6. For the Direction of traffic, choose ingress or egress.
7. For the Action on match, choose allow or deny.

8. Specify the Targets of the rule.

   • If you want the rule to apply to all instances in the network, choose All instances in the network.
   • If you want the rule to apply to select instances by network (target) tags, choose Specified target tags, then type the tags to which the rule should apply into the Target tags field.
   • If you want the rule to apply to select instances by associated service account, choose Specified service account, indicate whether the service account is in the current project or another one under Service account scope, and choose or type the service account name in the Target service account field.

9. For an ingress rule, specify the Source filter:

   • Choose IP ranges and type the CIDR blocks into the Source IP ranges field to define the source for incoming traffic by IP address ranges. Use 0.0.0.0/0 for a source from any network.
   • Choose Subnets then mark the ones you need from the Subnets pop-up button to define the source for incoming traffic by subnet name.
   • To limit source by network tag, choose Source tags, then type the network tags in to the Source tags field. For the limit on the number of source tags, see VPC Quotas and Limits. Filtering by source tag is only available if the target is not specified by service account. For more information, see filtering by service account vs.network tag.
   • To limit source by service account, choose Service account, indicate whether the service account is in the current project or another one under Service account scope, and choose or type the service account name in the Source service account field. Filtering by source service account is only available if the target is not specified by network tag. For more information, see filtering by service account vs. network tag.
   • Specify a Second source filter if desired. Secondary source filters cannot use the same filter criteria as the primary one.

10. For an egress rule, specify the Destination filter:

    • Choose IP ranges and type the CIDR blocks into the Destination IP ranges field to define the destination for outgoing traffic by IP address ranges. Use 0.0.0.0/0 to mean everywhere.
    • Choose Subnets then mark the ones you need from the Subnets pop-up button to define the destination for outgoing traffic by subnet name.

11. Define the Protocols and ports to which the rule will apply:

    • Select Allow all or Deny all, depending on the action, to have the rule apply to all protocols and ports.

    • Define specific protocols and ports:

      • Select tcp to include the TCP protocol and ports. Enter all or a comma delimited list of ports, such as 20-22, 80, 8080.
      • Select udp to include the UDP protocol and ports. Enter all or a comma delimited list of ports, such as 67-69, 123.
      • Select Other protocols to include protocols such as icmp or sctp.

12. (Optional) You can create the firewall rule but not enforce it by setting its enforcement state to disabled. Click Disable rule, then select Disabled.

13. (Optional) You can enable firewall rules logging:

    • Click Logs > On.
    • Click Turn on.

14. Click Create.

I wanted a way to do this without using an extra module. First turn list to string, then append to an array:

dataset_list = ''.join(input_list)
dataset_array = []
for item in dataset_list.split(';'): # comma, or other
    dataset_array.append(item)

Clearly, there is no perfect answer. However, if you want to allow the user to

1. select certain cells
2. allow them to change those cells, and
3. trap each click,even repeated clicks on the same cell,

then the easiest way seems to be to move the focus off the selected cell, so that clicking it will trigger a Select event.

One option is to move the focus as I suggested above, but this prevents cell editing. Another option is to extend the selection by one cell (left/right/up/down),because this permits editing of the original cell, but will trigger a Select event if that cell is clicked again on its own.

If you only wanted to trap selection of a single column of cells, you could insert a hidden column to the right, extend the selection to include the hidden cell to the right when the user clicked,and this gives you an editable cell which can be trapped every time it is clicked. The code is as follows

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
  'prevent Select event triggering again when we extend the selection below
  Application.EnableEvents = False
  Target.Resize(1, 2).Select
  Application.EnableEvents = True
End Sub

Newer versions: (from 8.4 - mentioned in release notes)

TABLE mytablename;

Longer but works on all versions:

SELECT * FROM mytablename;

You may wish to use \x first if it's a wide table, for readability.

For long data:

SELECT * FROM mytable LIMIT 10;

or similar.

For wide data (big rows), in the psql command line client, it's useful to use \x to show the rows in key/value form instead of tabulated, e.g.

 \x
SELECT * FROM mytable LIMIT 10;

Note that in all cases the semicolon at the end is important.

Many people will suggest you use MERGE, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, and it introduces other dangers:

• Use Caution with SQL Server's MERGE Statement

Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):

BEGIN TRANSACTION;

UPDATE dbo.table WITH (UPDLOCK, SERIALIZABLE) 
  SET ... WHERE PK = @PK;

IF @@ROWCOUNT = 0
BEGIN
  INSERT dbo.table(PK, ...) SELECT @PK, ...;
END

COMMIT TRANSACTION;

• Please stop using this UPSERT anti-pattern

A lot of folks will suggest this way:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;

BEGIN TRANSACTION;

IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
  UPDATE ...
END
ELSE
BEGIN
  INSERT ...
END
COMMIT TRANSACTION;

But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)

Others will suggest this way:

BEGIN TRY
  INSERT ...
END TRY
BEGIN CATCH
  IF ERROR_NUMBER() = 2627
    UPDATE ...
END CATCH

However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:

• Checking for potential constraint violations before entering TRY/CATCH
• Performance impact of different error handling techniques

Since ID is auto increment, you can also specify ID=NULL as,

LOAD XML LOCAL INFILE '/pathtofile/file.xml' INTO TABLE my_tablename SET ID=NULL;

Declare a Flask endpoint to accept POST input type and then do necessary steps. Use jQuery to post the data.

from flask import request

@app.route('/parse_data', methods=['GET', 'POST'])
def parse_data(data):
    if request.method == "POST":
         #perform action here

var value = $('.textbox').val();
$.ajax({
  type: 'POST',
  url: "{{ url_for('parse_data') }}",
  data: JSON.stringify(value),
  contentType: 'application/json',
  success: function(data){
    // do something with the received data
  }
});

The simplest possible solution I found was:

In your markup:

<a [href]="location.path()">Reload</a>

and in your component typescript file:

constructor(
        private location: Location
  ) { }

This limitation (of Windows) should be publicly announced! The issue for me is the combination of the following: Windows 10 + AMD CPU (with AMD-V/SMV) +/- Hyper Visor

I have no issues running: Intel (with VT-x) + Linux or AMD (with AMD-V) + Linux

Link to Android studio issue here:

Xamarin/Visual Studio seems to have a workaround, but I haven't tested it yet:

If you need to use Hyper-V for other emulators then I'd recommend using the Microsoft Android Emulator instead, which uses Hyper-V and can also be used with Xamarin Studio/Visual Studio. You can download it for free from here.

I will update this after I confirm it works. Wish I would have known this before purchasing a new machine.

UPDATE!! It does not work "Requires Intel ..." error message is shown

Final note:

*Must be revision F3 or grater or must be F2 with BIOS support. Presence or absence of SVM Disable or other virtualization options in the bios does not ensure presence of BIOS support. You should contact the OEM to ensure support of Hyper-V.

*Some AMD BIOS's have options to enable/disable SVM (virtualization assistance)

*Some BIOS's list this as SVM Disable and it's a double negative, i.e. you want to disable SVM disable to enable SVM.

*Some BIOS's list this as Secure Virtualization, thus enabling Secure Virtualization will enable SVM

*Must have No-Execute enabled in the BIOS, sometime this is referred to as NX or Execute Disable

*If you want to find CPU's that are F3 see AMD's guide http://products.amd.com/en-us/DesktopCPUFilter.aspx or http://products.amd.com/en-us/OpteronCPUFilter.aspx?f1=Second-Generation+AMD+Opteron%e2%84%a2

You can use the semver package to determine if a version satisfies a semantic version requirement. This is not the same as comparing two actual versions, but is a type of comparison.

For example, version 3.6.0+1234 should be the same as 3.6.0.

import semver
semver.match('3.6.0+1234', '==3.6.0')
# True

from packaging import version
version.parse('3.6.0+1234') == version.parse('3.6.0')
# False

from distutils.version import LooseVersion
LooseVersion('3.6.0+1234') == LooseVersion('3.6.0')
# False

Instead of using relative paths, you could also use the predefined macros of VS to achieve this.

$(ProjectDir) points to the directory of your .vcproj file, $(SolutionDir) is the directory of the .sln file.

You get a list of available macros when opening a project, go to
Properties → Configuration Properties → C/C++ → General
and hit the three dots:

In the upcoming dialog, hit Macros to see the macros that are predefined by the Studio (consult MSDN for their meaning):

You can use the Macros by typing $(MACRO_NAME) (note the $ and the round brackets).

try this:

git submodule sync
git submodule update

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;
        }
