Please check if you got the x64 edition of eclipse. Someone answered this just a few hours ago.

There actually is a trick how to execute a parallel operation in a specific fork-join pool. If you execute it as a task in a fork-join pool, it stays there and does not use the common one.

final int parallelism = 4;
ForkJoinPool forkJoinPool = null;
try {
    forkJoinPool = new ForkJoinPool(parallelism);
    final List<Integer> primes = forkJoinPool.submit(() ->
        // Parallel task here, for example
        IntStream.range(1, 1_000_000).parallel()
                .filter(PrimesPrint::isPrime)
                .boxed().collect(Collectors.toList())
    ).get();
    System.out.println(primes);
} catch (InterruptedException | ExecutionException e) {
    throw new RuntimeException(e);
} finally {
    if (forkJoinPool != null) {
        forkJoinPool.shutdown();
    }
}

The trick is based on ForkJoinTask.fork which specifies: "Arranges to asynchronously execute this task in the pool the current task is running in, if applicable, or using the ForkJoinPool.commonPool() if not inForkJoinPool()"

For my answer, it is worth remembering that the TPL (Task-Parallel-Library), Task class and TaskStatus enumeration were introduced prior to the async-await keywords and the async-await keywords were not the original motivation of the TPL.

In the context of methods marked as async, the resulting Task is not a Task representing the execution of the method, but a Task for the continuation of the method.

This is only able to make use of a few possible states:

• Canceled
• Faulted
• RanToCompletion
• WaitingForActivation

I understand that Runningcould appear to have been a better default than WaitingForActivation, however this could be misleading, as the majority of the time, an async method being executed is not actually running (i.e. it may be await-ing something else). The other option may have been to add a new value to TaskStatus, however this could have been a breaking change for existing applications and libraries.

All of this is very different to when making use of Task.Run which is a part of the original TPL, this is able to make use of all the possible values of the TaskStatus enumeration.

If you wish to keep track of the status of an async method, take a look at the IProgress(T) interface, this will allow you to report the ongoing progress. This blog post, Async in 4.5: Enabling Progress and Cancellation in Async APIs will provide further information on the use of the IProgress(T) interface.

Didn't work with ODBC-Bridge for me too. I got the way around to initialize ODBC connection using ODBC driver.

 import java.sql.*;  
 public class UserLogin
 {
     public static void main(String[] args)
     {
        try
        {    
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

            // C:\\databaseFileName.accdb" - location of your database 
           String url = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=" + "C:\\emp.accdb";

            // specify url, username, pasword - make sure these are valid 
            Connection conn = DriverManager.getConnection(url, "username", "password");

            System.out.println("Connection Succesfull");
         } 
         catch (Exception e) 
         {
            System.err.println("Got an exception! ");
            System.err.println(e.getMessage());

          }
      }
  }

Data content is so variable, I think the best form is to define it as "ObjectNode" and next create his own class to parse:

Finally:

private ObjectNode data;

Whenever a TypeInitializationException is thrown, check all initialization logic of the type you are referring to for the first time in the statement where the exception is thrown - in your case: Logger.

Initialization logic includes: the type's static constructor (which - if I didn't miss it - you do not have for Logger) and field initialization.

Field initialization is pretty much "uncritical" in Logger except for the following lines:

private static string s_bstCommonAppData = Path.Combine(s_commonAppData, "XXXX");
private static string s_bstUserDataDir = Path.Combine(s_bstCommonAppData, "UserData");
private static string s_commonAppData = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);

s_commonAppData is null at the point where Path.Combine(s_commonAppData, "XXXX"); is called. As far as I'm concerned, these initializations happen in the exact order you wrote them - so put s_commonAppData up by at least two lines ;)

I ran into this problem and fixed it by closing the input and output streams before closing the socket. Now I can disconnect and connect again with no issues.

https://stackoverflow.com/a/3039807/5688612

In Kotlin:

fun disconnect() {
    bluetoothSocket.inputStream.close()
    bluetoothSocket.outputStream.close()
    bluetoothSocket.close()
}

You can use this:

curl_setopt_array($ch, $options);
$resultado = curl_exec($ch);
$info = curl_getinfo($ch);
print_r($info["url"]);

From oracle documentation page on Joins

The join method allows one thread to wait for the completion of another.

If t1 is a Thread object whose thread is currently executing,

t1.join() : causes the current thread to pause execution until t1's thread terminates.

If t2 is a Thread object whose thread is currently executing,

t2.join(); causes the current thread to pause execution until t2's thread terminates.

join API is low level API, which has been introduced in earlier versions of java. Lot of things have been changed over a period of time (especially with jdk 1.5 release) on concurrency front.

You can achieve the same with java.util.concurrent API. Some of the examples are

1. Using invokeAll on ExecutorService
2. Using CountDownLatch
3. Using ForkJoinPool or newWorkStealingPool of Executors(since java 8)

Refer to related SE questions:

wait until all threads finish their work in java

There is a general problem: it's hard to mock time. Also, it's really bad practice to place long running/waiting code in a unit test.

So, for making a scheduling API testable, I used an interface with a real and a mock implementation like this:

public interface Clock {
    
    public long getCurrentMillis();
    
    public void sleep(long millis) throws InterruptedException;
    
}

public static class SystemClock implements Clock {

    @Override
    public long getCurrentMillis() {
        return System.currentTimeMillis();
    }

    @Override
    public void sleep(long millis) throws InterruptedException {
        Thread.sleep(millis);
    }
    
}

public static class MockClock implements Clock {

    private final AtomicLong currentTime = new AtomicLong(0);
    

    public MockClock() {
        this(System.currentTimeMillis());
    }
    
    public MockClock(long currentTime) {
        this.currentTime.set(currentTime);
    }
    

    @Override
    public long getCurrentMillis() {
        return currentTime.addAndGet(5);
    }

    @Override
    public void sleep(long millis) {
        currentTime.addAndGet(millis);
    }
    
}

With this, you could imitate time in your test:

@Test
public void testExpiration() {
    MockClock clock = new MockClock();
    SomeCacheObject sco = new SomeCacheObject();
    sco.putWithExpiration("foo", 1000);
    clock.sleep(2000) // wait for 2 seconds
    assertNull(sco.getIfNotExpired("foo"));
}

An advanced multi-threading mock for Clock is much more complex, of course, but you can make it with ThreadLocal references and a good time synchronization strategy, for example.

This is copied from my answer to another very similar post, hope it can help:

1) Start with maximum number of threads a system can support:

int Num_Threads =  thread::hardware_concurrency();

2) For an efficient threadpool implementation, once threads are created according to Num_Threads, it's better not to create new ones, or destroy old ones (by joining). There will be performance penalty, might even make your application goes slower than the serial version.

Each C++11 thread should be running in their function with an infinite loop, constantly waiting for new tasks to grab and run.

Here is how to attach such function to the thread pool:

int Num_Threads = thread::hardware_concurrency();
vector<thread> Pool;
for(int ii = 0; ii < Num_Threads; ii++)
{  Pool.push_back(thread(Infinite_loop_function));}

3) The Infinite_loop_function

This is a "while(true)" loop waiting for the task queue

void The_Pool:: Infinite_loop_function()
{
    while(true)
    {
        {
            unique_lock<mutex> lock(Queue_Mutex);

            condition.wait(lock, []{return !Queue.empty() || terminate_pool});
            Job = Queue.front();
            Queue.pop();
        }
        Job(); // function<void()> type
    }
};

4) Make a function to add job to your Queue

void The_Pool:: Add_Job(function<void()> New_Job)
{
    {
        unique_lock<mutex> lock(Queue_Mutex);
        Queue.push(New_Job);
    }
    condition.notify_one();
}

5) Bind an arbitrary function to your Queue

Pool_Obj.Add_Job(std::bind(&Some_Class::Some_Method, &Some_object));

Once you integrate these ingredients, you have your own dynamic threading pool. These threads always run, waiting for job to do.

I apologize if there are some syntax errors, I typed these code and and I have a bad memory. Sorry that I cannot provide you the complete thread pool code, that would violate my job integrity.

Edit: to terminate the pool, call the shutdown() method:

XXXX::shutdown(){
{
    unique_lock<mutex> lock(threadpool_mutex);
    terminate_pool = true;} // use this flag in condition.wait

    condition.notify_all(); // wake up all threads.

    // Join all threads.
    for(std::thread &every_thread : thread_vector)
    {   every_thread.join();}

    thread_vector.clear();  
    stopped = true; // use this flag in destructor, if not set, call shutdown() 
}

If you need run thread predioticly with different codes here is example:

Listener:

public interface ESLThreadListener {

    public List onBackground();

    public void onPostExecute(List list);

}

Thread Class

public class ESLThread extends AsyncTask<Void, Void, List> {


    private ESLThreadListener mListener;

    public ESLThread() {

        if(mListener != null){

            mListener.onBackground();
        }
    }

    @Override
    protected List doInBackground(Void... params) {

        if(mListener != null){

            List list = mListener.onBackground();

            return list;
        }

        return null;
    }

    @Override
    protected void onPostExecute(List t) {
        if(mListener != null){

            if ( t != null) {
                mListener.onPostExecute(t);
            }
        }

    }


    public void setListener(ESLThreadListener mListener){

        this.mListener = mListener;
    }
}

Run different codes:

  ESLThread thread = new ESLThread();
                        thread.setListener(new ESLThreadListener() {
                            @Override
                            public List onBackground() {
                                List<EntityShoppingListItems>  data = RoomDB.getDatabase(context).sliDAO().getSL(fId);

                                return data;

                            }

                            @Override
                            public void onPostExecute(List t) {

                                List<EntityShoppingListItems> data = (List<EntityShoppingListItems>)t;
                                adapter.setList(data);
                            }
                        });

                        thread.execute();

I know it's a bit old but I ran in the same problem today. I wanted to install eclipse on my vm with xubuntu. Because I've had problems with the latest eclipse version 2019-06 I tried with Oxygen. So I went to eclipse.org and downloaded oxygen. When running oxygen, the problem with merketplace not reachable occurs. So I downloaded the eclipse installer not immediatly the oxygen. After that I can use eclipse as expectet ( all versions)

You are debugging two or more times. so the application may run more at a time. Then only this issue will occur. You should close all debugging applications using task-manager, Then debug again.

Everywhere inside the query string, the wildcard should be ? instead of '?'. That should solve the problem.

EDIT :

To add to that, you need to change date '?' to to_date(?, 'yyyy-mm-dd'). Please try that and let me know.

Do you want to keep your database on mobile? Use sqlite instead of mysql.

If the idea is to keep database on server and access from mobile. Use a webservice to fetch/ modify data.

Ctrl+C terminates the main thread, but because your threads aren't in daemon mode, they keep running, and that keeps the process alive. We can make them daemons:

f = FirstThread()
f.daemon = True
f.start()
s = SecondThread()
s.daemon = True
s.start()

But then there's another problem - once the main thread has started your threads, there's nothing else for it to do. So it exits, and the threads are destroyed instantly. So let's keep the main thread alive:

import time
while True:
    time.sleep(1)

Now it will keep print 'first' and 'second' until you hit Ctrl+C.

Edit: as commenters have pointed out, the daemon threads may not get a chance to clean up things like temporary files. If you need that, then catch the KeyboardInterrupt on the main thread and have it co-ordinate cleanup and shutdown. But in many cases, letting daemon threads die suddenly is probably good enough.

Everything that interacts with the UI must be called in the UI thread (unless it is a frozen object). To do that, you can use the dispatcher.

var disp = /* Get the UI dispatcher, each WPF object has a dispatcher which you can query*/
disp.BeginInvoke(DispatcherPriority.Normal,
        (Action)(() => /*Do your UI Stuff here*/));

I use BeginInvoke here, usually a backgroundworker doesn't need to wait that the UI updates. If you want to wait, you can use Invoke. But you should be careful not to call BeginInvoke to fast to often, this can get really nasty.

By the way, The BackgroundWorker class helps with this kind of taks. It allows Reporting changes, like a percentage and dispatches this automatically from the Background thread into the ui thread. For the most thread <> update ui tasks the BackgroundWorker is a great tool.

Jon's disassemblies show, that the difference between the two versions is that the fast version uses a pair of registers (esi,edi) to store one of the local variables where the slow version doesn't.

The JIT compiler makes different assumptions regarding register use for code that contains a try-catch block vs. code which doesn't. This causes it to make different register allocation choices. In this case, this favors the code with the try-catch block. Different code may lead to the opposite effect, so I would not count this as a general-purpose speed-up technique.

In the end, it's very hard to tell which code will end up running the fastest. Something like register allocation and the factors that influence it are such low-level implementation details that I don't see how any specific technique could reliably produce faster code.

For example, consider the following two methods. They were adapted from a real-life example:

interface IIndexed { int this[int index] { get; set; } }
struct StructArray : IIndexed { 
    public int[] Array;
    public int this[int index] {
        get { return Array[index]; }
        set { Array[index] = value; }
    }
}

static int Generic<T>(int length, T a, T b) where T : IIndexed {
    int sum = 0;
    for (int i = 0; i < length; i++)
        sum += a[i] * b[i];
    return sum;
}
static int Specialized(int length, StructArray a, StructArray b) {
    int sum = 0;
    for (int i = 0; i < length; i++)
        sum += a[i] * b[i];
    return sum;
}

One is a generic version of the other. Replacing the generic type with StructArray would make the methods identical. Because StructArray is a value type, it gets its own compiled version of the generic method. Yet the actual running time is significantly longer than the specialized method's, but only for x86. For x64, the timings are pretty much identical. In other cases, I've observed differences for x64 as well.

If you have Model or transfer object passed to GET method but still have this error, check naming of your variables. Use entity/transfer object names in camelcase. I had BusinessTripDTO object and named it 'trip' for short. It caused this error to occure, even I had all other parts in place. Renaming varaibles to businessTripDTO in Java and Thymeleaf solved this problem for me.

Many answers here describe dangerous methods where they instantiate a file input stream but do not get a reference to the input stream in order to close the stream later. This results in dangling input streams and memory leaks. The correct way of loading the properties should be similar to following:

    Properties prop = new Properties();
    try(InputStream fis = new FileInputStream("myProp.properties")) {
        prop.load(fis);
    }
    catch(Exception e) {
        System.out.println("Unable to find the specified properties file");
        e.printStackTrace();
        return;
    }

Note the instantiating of the file input stream in try-with-resources block. Since a FileInputStream is autocloseable, it will be automatically closed after the try-with-resources block is exited. If you want to use a simple try block, you must explicitly close it using fis.close(); in the finally block.

Place the image in a source folder, not a regular folder. That is: right-click on project -> New -> Source Folder. Place the image in that source folder. Then:

InputStream input = classLoader.getResourceAsStream("image.jpg");

Note that the path is omitted. That's because the image is directly in the root of the path. You can add folders under your source folder to break it down further if you like. Or you can put the image under your existing source folder (usually called src).

public static DateTime ConvertDateTime(string Date)
    {
        DateTime date=new DateTime();                        
        try
        {
            string CurrentPattern = Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern;                
            string[] Split = new string[] {"-","/",@"\","."};
            string[] Patternvalue = CurrentPattern.Split(Split,StringSplitOptions.None);
            string[] DateSplit = Date.Split(Split,StringSplitOptions.None);
            string NewDate = "";
            if (Patternvalue[0].ToLower().Contains("d") == true && Patternvalue[1].ToLower().Contains("m")==true && Patternvalue[2].ToLower().Contains("y")==true)
            {
                NewDate = DateSplit[1] + "/" + DateSplit[0] + "/" + DateSplit[2];
            }
            else if (Patternvalue[0].ToLower().Contains("m") == true && Patternvalue[1].ToLower().Contains("d")==true && Patternvalue[2].ToLower().Contains("y")==true)
            {
                NewDate = DateSplit[0] + "/" + DateSplit[1] + "/" + DateSplit[2];
            }
            else if (Patternvalue[0].ToLower().Contains("y") == true && Patternvalue[1].ToLower().Contains("m")==true && Patternvalue[2].ToLower().Contains("d")==true)
            {
                NewDate = DateSplit[2] + "/" + DateSplit[0] + "/" + DateSplit[1];
            }
            else if (Patternvalue[0].ToLower().Contains("y") == true && Patternvalue[1].ToLower().Contains("d")==true && Patternvalue[2].ToLower().Contains("m")==true)

            }
            date = DateTime.Parse(NewDate, Thread.CurrentThread.CurrentCulture);

1. Add using

using System.ComponentModel;

2. Declare Background Worker:

private readonly BackgroundWorker worker = new BackgroundWorker();

3. Subscribe to events:

worker.DoWork += worker_DoWork;
worker.RunWorkerCompleted += worker_RunWorkerCompleted;

4. Implement two methods:

private void worker_DoWork(object sender, DoWorkEventArgs e)
{
  // run all background tasks here
}

private void worker_RunWorkerCompleted(object sender, 
                                           RunWorkerCompletedEventArgs e)
{
  //update ui once worker complete his work
}

5. Run worker async whenever your need.

worker.RunWorkerAsync();

6. Track progress (optional, but often useful)

   a) subscribe to ProgressChanged event and use ReportProgress(Int32) in DoWork

   b) set worker.WorkerReportsProgress = true; (credits to @zagy)

Something like this (I'm not a VB programmer)

Public Class MyParameters
    public Name As String
    public Number As Integer
End Class



newThread as thread = new Thread( AddressOf DoWork)
Dim parameters As New MyParameters
parameters.Name = "Arne"
newThread.Start(parameters);

public shared sub DoWork(byval data as object)
{
    dim parameters = CType(data, Parameters)

}

I would say in some cases it's ok to do nothing. Probably not something you should be doing by default, but in case there should be no way for the interrupt to happen, I'm not sure what else to do (probably logging error, but that does not affect program flow).

One case would be in case you have a task (blocking) queue. In case you have a daemon Thread handling these tasks and you do not interrupt the Thread by yourself (to my knowledge the jvm does not interrupt daemon threads on jvm shutdown), I see no way for the interrupt to happen, and therefore it could be just ignored. (I do know that a daemon thread may be killed by the jvm at any time and therefore are unsuitable in some cases).

EDIT: Another case might be guarded blocks, at least based on Oracle's tutorial at: http://docs.oracle.com/javase/tutorial/essential/concurrency/guardmeth.html

I tried a lot of ways and functions that suggested above, but they didn't work in my project. Anyway I have found solution and here it is:

try {
    InputStream path = this.getClass().getClassLoader().getResourceAsStream("img/left-hand.png");
    img = ImageIO.read(path);
} catch (IOException e) {
    e.printStackTrace();
}

My answer does 100% fit to this problem, but I want to document my solution and the trap behind it, since the Exception is the same.

My port was always in use testing a Jetty in a Junit testcase. Problem was Google's code pro on Eclipse, which, I guess, was testing in the background and thus starting jetty before me all the time. Workaround: let Eclipse open *.java files always w/ the Java editor instead of Google's Junit editor. That seems to help.

First what you have to do, before changing web.xml is to make sure your ManagedBean implements Serializable:

@ManagedBean
@ViewScoped
public class Login implements Serializable {
}

Especially if you use MyFaces

First error: You're casting a ClientThread as a String for some reason.

Second error: You're not calling remove on your List.

Is is homework? If so, you might want to use the tag.

You can use this implementation that ExecutorService provides

invokeAll(Collection<? extends Callable<T>> tasks,long timeout, TimeUnit unit)
as

executor.invokeAll(Arrays.asList(task), 2 , TimeUnit.SECONDS);

However, in my case, I could not as Arrays.asList took extra 20ms.

First, this is not an error. The 3xx denotes a redirection. The real errors are 4xx (client error) and 5xx (server error).

If a client gets a 304 Not Modified, then it's the client's responsibility to display the resouce in question from its own cache. In general, the proxy shouldn't worry about this. It's just the messenger.

If you simply call interrupt(), the thread will not automatically be closed. Instead, the Thread might even continue living, if isInterrupted() is implemented accordingly. The only way to guaranteedly close a thread, as asked for by OP, is

Thread.currentThread().stop();

Method is deprecated, however.

Calling return only returns from the current method. This only terminates the thread if you're at its top level.

Nevertheless, you should work with interrupt() and build your code around it.

Each class will use its own classloader to load other classes. So if ClassA.class references ClassB.class then ClassB needs to be on the classpath of the classloader of ClassA, or its parents.

The thread context classloader is the current classloader for the current thread. An object can be created from a class in ClassLoaderC and then passed to a thread owned by ClassLoaderD. In this case the object needs to use Thread.currentThread().getContextClassLoader() directly if it wants to load resources that are not available on its own classloader.

To get the OS ID use:

AppDomain.GetCurrentThreadId()

There are subtle differences as to how the fileName you are passing is interpreted. Basically, you have 2 different methods: ClassLoader.getResourceAsStream() and Class.getResourceAsStream(). These two methods will locate the resource differently.

In Class.getResourceAsStream(path), the path is interpreted as a path local to the package of the class you are calling it from. For example calling, String.class.getResourceAsStream("myfile.txt") will look for a file in your classpath at the following location: "java/lang/myfile.txt". If your path starts with a /, then it will be considered an absolute path, and will start searching from the root of the classpath. So calling String.class.getResourceAsStream("/myfile.txt") will look at the following location in your class path ./myfile.txt.

ClassLoader.getResourceAsStream(path) will consider all paths to be absolute paths. So calling String.class.getClassLoader().getResourceAsStream("myfile.txt") and String.class.getClassLoader().getResourceAsStream("/myfile.txt") will both look for a file in your classpath at the following location: ./myfile.txt.

Everytime I mention a location in this post, it could be a location in your filesystem itself, or inside the corresponding jar file, depending on the Class and/or ClassLoader you are loading the resource from.

In your case, you are loading the class from an Application Server, so your should use Thread.currentThread().getContextClassLoader().getResourceAsStream(fileName) instead of this.getClass().getClassLoader().getResourceAsStream(fileName). this.getClass().getResourceAsStream() will also work.

Read this article for more detailed information about that particular problem.

Warning for users of Tomcat 7 and below

One of the answers to this question states that my explanation seems to be incorrect for Tomcat 7. I've tried to look around to see why that would be the case.

So I've looked at the source code of Tomcat's WebAppClassLoader for several versions of Tomcat. The implementation of findResource(String name) (which is utimately responsible for producing the URL to the requested resource) is virtually identical in Tomcat 6 and Tomcat 7, but is different in Tomcat 8.

In versions 6 and 7, the implementation does not attempt to normalize the resource name. This means that in these versions, classLoader.getResourceAsStream("/resource.txt") may not produce the same result as classLoader.getResourceAsStream("resource.txt") event though it should (since that what the Javadoc specifies). [source code]

In version 8 though, the resource name is normalized to guarantee that the absolute version of the resource name is the one that is used. Therefore, in Tomcat 8, the two calls described above should always return the same result. [source code]

As a result, you have to be extra careful when using ClassLoader.getResourceAsStream() or Class.getResourceAsStream() on Tomcat versions earlier than 8. And you must also keep in mind that class.getResourceAsStream("/resource.txt") actually calls classLoader.getResourceAsStream("resource.txt") (the leading / is stripped).

This is what I came op for a thread safe bounded blocking queue.

using System;
using System.Collections.Generic;
using System.Text;
using System.Threading;

public class BlockingBuffer<T>
{
    private Object t_lock;
    private Semaphore sema_NotEmpty;
    private Semaphore sema_NotFull;
    private T[] buf;

    private int getFromIndex;
    private int putToIndex;
    private int size;
    private int numItems;

    public BlockingBuffer(int Capacity)
    {
        if (Capacity <= 0)
            throw new ArgumentOutOfRangeException("Capacity must be larger than 0");

        t_lock = new Object();
        buf = new T[Capacity];
        sema_NotEmpty = new Semaphore(0, Capacity);
        sema_NotFull = new Semaphore(Capacity, Capacity);
        getFromIndex = 0;
        putToIndex = 0;
        size = Capacity;
        numItems = 0;
    }

    public void put(T item)
    {
        sema_NotFull.WaitOne();
        lock (t_lock)
        {
            while (numItems == size)
            {
                Monitor.Pulse(t_lock);
                Monitor.Wait(t_lock);
            }

            buf[putToIndex++] = item;

            if (putToIndex == size)
                putToIndex = 0;

            numItems++;

            Monitor.Pulse(t_lock);

        }
        sema_NotEmpty.Release();


    }

    public T take()
    {
        T item;

        sema_NotEmpty.WaitOne();
        lock (t_lock)
        {

            while (numItems == 0)
            {
                Monitor.Pulse(t_lock);
                Monitor.Wait(t_lock);
            }

            item = buf[getFromIndex++];

            if (getFromIndex == size)
                getFromIndex = 0;

            numItems--;

            Monitor.Pulse(t_lock);

        }
        sema_NotFull.Release();

        return item;
    }
}

DefaultThreadCurrentCulture and DefaultThreadCurrentUICulture are present in Framework 4.0 too, but they are Private. Using Reflection you can easily set them. This will affect all threads where CurrentCulture is not explicitly set (running threads too).

Public Sub SetDefaultThreadCurrentCulture(paCulture As CultureInfo)
    Thread.CurrentThread.CurrentCulture.GetType().GetProperty("DefaultThreadCurrentCulture").SetValue(Thread.CurrentThread.CurrentCulture, paCulture, Nothing)
    Thread.CurrentThread.CurrentCulture.GetType().GetProperty("DefaultThreadCurrentUICulture").SetValue(Thread.CurrentThread.CurrentCulture, paCulture, Nothing)
End Sub

One thing that got this working for me is to make sure that github.com is in ~jenkins/.ssh/known_hosts.

To understand queue method, you have to understand how jQuery does animation. If you write multiple animate method calls one after the other, jQuery creates an 'internal' queue and adds these method calls to it. Then it runs those animate calls one by one.

Consider following code.

function nonStopAnimation()
{
    //These multiple animate calls are queued to run one after
    //the other by jQuery.
    //This is the reason that nonStopAnimation method will return immeidately
    //after queuing these calls. 
    $('#box').animate({ left: '+=500'}, 4000);
    $('#box').animate({ top: '+=500'}, 4000);
    $('#box').animate({ left: '-=500'}, 4000);

    //By calling the same function at the end of last animation, we can
    //create non stop animation. 
    $('#box').animate({ top: '-=500'}, 4000 , nonStopAnimation);
}

The 'queue'/'dequeue' method gives you control over this 'animation queue'.

By default the animation queue is named 'fx'. I have created a sample page here which has various examples which will illustrate how the queue method could be used.

http://jsbin.com/zoluge/1/edit?html,output

Code for above sample page:

$(document).ready(function() {
    $('#nonStopAnimation').click(nonStopAnimation);

    $('#stopAnimationQueue').click(function() {
        //By default all animation for particular 'selector'
        //are queued in queue named 'fx'.
        //By clearning that queue, you can stop the animation.
        $('#box').queue('fx', []);
    });

    $('#addAnimation').click(function() {
        $('#box').queue(function() {
            $(this).animate({ height : '-=25'}, 2000);
            //De-queue our newly queued function so that queues
            //can keep running.
            $(this).dequeue();
        });
    });

    $('#stopAnimation').click(function() {
        $('#box').stop();
    });

    setInterval(function() {
        $('#currentQueueLength').html(
         'Current Animation Queue Length for #box ' + 
          $('#box').queue('fx').length
        );
    }, 2000);
});

function nonStopAnimation()
{
    //These multiple animate calls are queued to run one after
    //the other by jQuery.
    $('#box').animate({ left: '+=500'}, 4000);
    $('#box').animate({ top: '+=500'}, 4000);
    $('#box').animate({ left: '-=500'}, 4000);
    $('#box').animate({ top: '-=500'}, 4000, nonStopAnimation);
}

Now you may ask, why should I bother with this queue? Normally, you wont. But if you have a complicated animation sequence which you want to control, then queue/dequeue methods are your friend.

Also see this interesting conversation on jQuery group about creating a complicated animation sequence.

http://groups.google.com/group/jquery-en/browse_thread/thread/b398ad505a9b0512/f4f3e841eab5f5a2?lnk=gst

Demo of the animation:

Let me know if you still have questions.

I think this may answer your question.

Non-static method ..... should not be called statically

If the method is not static you need to initialize it like so:

$var = new ClassName();
$var->method();

Or, in PHP 5.4+, you can use this syntax:

(new ClassName)->method();

For Netbeans 2020 September version. JDK 11

(Suggesting this for Gradle project only)

1. create libs folder in src/main/java folder of the project

2. copy past all library jars in there

3. open build.gradle in files tab of project window in project's root

4. correct main class (mine is mainClassName = 'uz.ManipulatorIkrom')

5. and in dependencies add next string:

apply plugin: 'java' 
apply plugin: 'jacoco' 
apply plugin: 'application'
description = 'testing netbeans'
mainClassName = 'uz.ManipulatorIkrom' //4th step
repositories {
    jcenter()
}
dependencies {
    implementation fileTree(dir: 'src/main/java/libs', include: '*.jar') //5th step   
}

6. save, clean-build and then run the app

Just an upgrade from above answers

function strsearch($findme, $source){
    if(is_array($findme)){
        if(str_replace($findme, '', $source) != $source){
            return true;
        }
    }else{
        if(strpos($source,$findme)){
            return true;
        }
    }
    return false;
}

Here is an other modern approach:

const checkExtension = (id, src, callback) => {
    let e = new Image()
    e.src = 'chrome-extension://'+ id +'/'+ src
    e.onload = () => callback(1), e.onerror = () => callback(0)
}

// "src" must be included to "web_accessible_resources" in manifest.json
checkExtension('gighmmpiobklfepjocnamgkkbiglidom', 'icons/icon24.png', (ok) => {
    console.log('AdBlock: %s', ok ? 'installed' : 'not installed')
})
checkExtension('bhlhnicpbhignbdhedgjhgdocnmhomnp', 'images/checkmark-icon.png', (ok) => {
    console.log('ColorZilla: %s', ok ? 'installed' : 'not installed')
})

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

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

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

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

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

#test_case_1.py
import bar
from mock import patch

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

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

#test_case_2.py
import foo
from mock import patch

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

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

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

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

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

I have a PHP threading class that's been running flawlessly in a production environment for over two years now.

There are another scenario which was happening for my customers. This was happening normally in certain time because of shift changes and users needed to login with different user. Here is a scenario which Anti forgery system protects system by generation this error:

1- Once close/open your browser. 2- Go to your website and login with "User A" 3- Open new Tab in browser and enter the same address site. (You can see your site Home page without any authentication) 4- Logout from your site and Login with another User(User B) in second tab. 5- Now go back to the first Tab which you logged in by "User A". You can still see the page but any action in this tab will make the error. Because your cookie is already updated by "User B" and you are trying to send a request by an invalid user. (User A)

This is probably because an empty line at the end of your input file.

Try this:

for x in f:
    try:
        print int(x.strip(),16)
    except ValueError:
        print "Invalid input:", x

You can call it like that:

<!DOCTYPE html>
<html lang="en">
    <head>
        <script type="text/javascript">
            var person = { name: 'Joe Blow' };
            function myfunction() {
               document.write(person.name);
            }
        </script>
    </head>
    <body>
        <script type="text/javascript">
            myfunction();
        </script>
    </body>
</html>

The result should be page with the only content: Joe Blow

Look here: http://jsfiddle.net/HWreP/

Best regards!

function urlIsOk($url)
{
    $headers = @get_headers($url);
    $httpStatus = intval(substr($headers[0], 9, 3));
    if ($httpStatus<400)
    {
        return true;
    }
    return false;
}

You've got a few things going on there. One, why a class? Do you actually have multiple of these on the page? The CSS suggests you can't. If not you should use an ID - it's faster to select both in CSS and jQuery:

<div id=bottomMenu>You read it all.</div>

Second you've got a few crazy things going on in that CSS - in particular the z-index is supposed to just be a number, not measured in pixels. It specifies what layer this tag is on, where each higher number is closer to the user (or put another way, on top of/occluding tags with lower z-indexes).

The animation you're trying to do is basically .fadeIn(), so just set the div to display: none; initially and use .fadeIn() to animate it:

$('#bottomMenu').fadeIn(2000);

.fadeIn() works by first doing display: (whatever the proper display property is for the tag), opacity: 0, then gradually ratcheting up the opacity.

Full working example:

http://jsfiddle.net/b9chris/sMyfT/

CSS:

#bottomMenu {
    display: none;
    position: fixed;
    left: 0; bottom: 0;
    width: 100%; height: 60px;
    border-top: 1px solid #000;
    background: #fff;
    z-index: 1;
}

JS:

var $win = $(window);

function checkScroll() {
    if ($win.scrollTop() > 100) {
        $win.off('scroll', checkScroll);
        $('#bottomMenu').fadeIn(2000);
    }
}

$win.scroll(checkScroll);

It is stretching because align-self default value is stretch. Set align-self to center.

align-self: center;

See documentation here: align-self

On Windows, you can also use the Win32 File Namespace prefixed with \\?\ to refer to your local directories:

\\?\C:\my_dir

See this answer for description.

String[] elements = { "a", "a", "a", "a" };

for( int i = 0; i < elements.length - 1; i++)
{
    String element = elements[i];
    String nextElement = elements[i+1];
}

Note that in this case, elements.length is 4, so you want to iterate from [0,2] to get elements 0,1, 1,2 and 2,3.

[Ljava.lang.Object; is the name for Object[].class, the java.lang.Class representing the class of array of Object.

The naming scheme is documented in Class.getName():

If this class object represents a reference type that is not an array type then the binary name of the class is returned, as specified by the Java Language Specification (§13.1).

If this class object represents a primitive type or void, then the name returned is the Java language keyword corresponding to the primitive type or void.

If this class object represents a class of arrays, then the internal form of the name consists of the name of the element type preceded by one or more '[' characters representing the depth of the array nesting. The encoding of element type names is as follows:

Element Type        Encoding
boolean             Z
byte                B
char                C
double              D
float               F
int                 I
long                J
short               S 
class or interface  Lclassname;

Yours is the last on that list. Here are some examples:

// xxxxx varies
System.out.println(new int[0][0][7]); // [[[I@xxxxx
System.out.println(new String[4][2]); // [[Ljava.lang.String;@xxxxx
System.out.println(new boolean[256]); // [Z@xxxxx

The reason why the toString() method on arrays returns String in this format is because arrays do not @Override the method inherited from Object, which is specified as follows:

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

getClass().getName() + '@' + Integer.toHexString(hashCode())

Note: you can not rely on the toString() of any arbitrary object to follow the above specification, since they can (and usually do) @Override it to return something else. The more reliable way of inspecting the type of an arbitrary object is to invoke getClass() on it (a final method inherited from Object) and then reflecting on the returned Class object. Ideally, though, the API should've been designed such that reflection is not necessary (see Effective Java 2nd Edition, Item 53: Prefer interfaces to reflection).

On a more "useful" toString for arrays

java.util.Arrays provides toString overloads for primitive arrays and Object[]. There is also deepToString that you may want to use for nested arrays.

Here are some examples:

int[] nums = { 1, 2, 3 };

System.out.println(nums);
// [I@xxxxx

System.out.println(Arrays.toString(nums));
// [1, 2, 3]

int[][] table = {
        { 1, },
        { 2, 3, },
        { 4, 5, 6, },
};

System.out.println(Arrays.toString(table));
// [[I@xxxxx, [I@yyyyy, [I@zzzzz]

System.out.println(Arrays.deepToString(table));
// [[1], [2, 3], [4, 5, 6]]

There are also Arrays.equals and Arrays.deepEquals that perform array equality comparison by their elements, among many other array-related utility methods.

You can also use

border-left: 9vw solid #F5E5D6;
border-right: 9vw solid #F5E5D6;     

OR

border: 9vw solid #F5E5D6;

No need for pipes, xargs, exec, or anything:

find . -name .svn -delete

Edit: Just kidding, evidently -delete calls unlinkat() under the hood, so it behaves like unlink or rmdir and will refuse to operate on directories containing files.

I have figured out how this is done for Sony devices.

I've blogged about it here. I've also posted a seperate SO question about this here.

Sony devices use a class named BadgeReciever.

1. Declare the com.sonyericsson.home.permission.BROADCAST_BADGE permission in your manifest file:

2. Broadcast an Intent to the BadgeReceiver:

   Intent intent = new Intent();
   
   intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", "com.yourdomain.yourapp.MainActivity");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", "99");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", "com.yourdomain.yourapp");
   
   sendBroadcast(intent);
   

3. Done. Once this Intent is broadcast the launcher should show a badge on your application icon.

4. To remove the badge again, simply send a new broadcast, this time with SHOW_MESSAGE set to false:

   intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", false);
   

I've excluded details on how I found this to keep the answer short, but it's all available in the blog. Might be an interesting read for someone.

Pure Virtual Functions are mostly used to define:

a) abstract classes

These are base classes where you have to derive from them and then implement the pure virtual functions.

b) interfaces

These are 'empty' classes where all functions are pure virtual and hence you have to derive and then implement all of the functions.

Pure virtual functions are actually functions which have no implementation in base class and have to be implemented in derived class.

Use the string's constructor

basic_string(const charT* s,size_type n, const Allocator& a = Allocator());

EDIT:

OK, then if the C string length is not given explicitly, use the ctor:

basic_string(const charT* s, const Allocator& a = Allocator());

You can try this. Function below sets all values of object's properties to undefined. Works as well with nested objects.

var clearObjectValues = (objToClear) => {
    Object.keys(objToClear).forEach((param) => {
        if ( (objToClear[param]).toString() === "[object Object]" ) {
            clearObjectValues(objToClear[param]);
        } else {
            objToClear[param] = undefined;
        }
    })
    return objToClear;
};

Amplifying on baz's answer, if you need to enumerate the argument list with an index (such as to search for a specific word), you can do this without copying the list or mutating it.

Say you want to split an argument list at a double-dash ("--") and pass the arguments before the dashes to one command, and the arguments after the dashes to another:

 toolwrapper() {
   for i in $(seq 1 $#); do
     [[ "${!i}" == "--" ]] && break
   done || return $? # returns error status if we don't "break"

   echo "dashes at $i"
   echo "Before dashes: ${@:1:i-1}"
   echo "After dashes: ${@:i+1:$#}"
 }

Results should look like this:

 $ toolwrapper args for first tool -- and these are for the second
 dashes at 5
 Before dashes: args for first tool
 After dashes: and these are for the second

:: savevars.bat

Here's an example of a transaction that will rollback on error and return the error code.

This is assuming that autocommit is set to 0. Hope this helps.

DELETE from table_name where rowid not in (select min(rowid) FROM table_name group by column_name);

and you can also delete duplicate records in another way

DELETE from table_name a where rowid > (select min(rowid) FROM table_name b where a.column=b.column);

With VS 2017, debugging ASP.NET project with Chrome doesn't sign you in with your Google account.

I personally was searching for something to let me compute the multiline string area, so I could determine if given area is big enough to print the string - with preserving specific font.

private static Hashtable hash = new Hashtable();
private Font font;
private LineBreakMeasurer lineBreakMeasurer;
private int start, end;

public PixelLengthCheck(Font font) {
    this.font = font;
}

public boolean tryIfStringFits(String textToMeasure, Dimension areaToFit) {
    AttributedString attributedString = new AttributedString(textToMeasure, hash);
    attributedString.addAttribute(TextAttribute.FONT, font);
    AttributedCharacterIterator attributedCharacterIterator =
            attributedString.getIterator();
    start = attributedCharacterIterator.getBeginIndex();
    end = attributedCharacterIterator.getEndIndex();

    lineBreakMeasurer = new LineBreakMeasurer(attributedCharacterIterator,
            new FontRenderContext(null, false, false));

    float width = (float) areaToFit.width;
    float height = 0;
    lineBreakMeasurer.setPosition(start);

    while (lineBreakMeasurer.getPosition() < end) {
        TextLayout textLayout = lineBreakMeasurer.nextLayout(width);
        height += textLayout.getAscent();
        height += textLayout.getDescent() + textLayout.getLeading();
    }

    boolean res = height <= areaToFit.getHeight();

    return res;
}

'''

If the python version you installed is 3.6.1, you can print strings and a variable through
a single line of code.
For example the first string is "I have", the second string is "US
Dollars" and the variable, **card.price** is equal to 300, we can write
the code this way:

'''

print("I have", card.price, "US Dollars")

#The print() function outputs strings to the screen.  
#The comma lets you concatenate and print strings and variables together in a single line of code.

HTML:

<select id="autoship_option" data-placeholder="Choose Option..." 
        style="width: 175px;" class="chzn-select">
    <option value=""></option>
    <option value="active">Active Autoship</option>
</select>
<button id="rs">Click to reset</button>

JS:

$('#rs').on('click', function(){
    $('autoship_option').find('option:selected').removeAttr('selected');
});

Fiddle: http://jsfiddle.net/Z8nE8/

For example, like this:

const querystring = require('querystring');
const https = require('https');

var postData = querystring.stringify({
    'msg' : 'Hello World!'
});

var options = {
  hostname: 'posttestserver.com',
  port: 443,
  path: '/post.php',
  method: 'POST',
  headers: {
       'Content-Type': 'application/x-www-form-urlencoded',
       'Content-Length': postData.length
     }
};

var req = https.request(options, (res) => {
  console.log('statusCode:', res.statusCode);
  console.log('headers:', res.headers);

  res.on('data', (d) => {
    process.stdout.write(d);
  });
});

req.on('error', (e) => {
  console.error(e);
});

req.write(postData);
req.end();

Those settings (core.whitespace and apply.whitespace) are not there to remove trailing whitespace but to:

• core.whitespace: detect them, and raise errors
• apply.whitespace: and strip them, but only during patch, not "always automatically"

I believe the git hook pre-commit would do a better job for that (includes removing trailing whitespace)

Note that at any given time you can choose to not run the pre-commit hook:

• temporarily: git commit --no-verify .
• permanently: cd .git/hooks/ ; chmod -x pre-commit

Warning: by default, a pre-commit script (like this one), has not a "remove trailing" feature", but a "warning" feature like:

if (/\s$/) {
    bad_line("trailing whitespace", $_);
}

You could however build a better pre-commit hook, especially when you consider that:

Committing in Git with only some changes added to the staging area still results in an “atomic” revision that may never have existed as a working copy and may not work.

For instance, oldman proposes in another answer a pre-commit hook which detects and remove whitespace.
Since that hook get the file name of each file, I would recommend to be careful for certain type of files: you don't want to remove trailing whitespace in .md (markdown) files!

Try this it works

<ul class="sub-menu" type="none">
           <li class="sub-menu-list" ng-repeat="menu in list.components">
               <a class="sub-menu-link">
                   {{ menu.component }}
               </a>
           </li>
        </ul>

Use:

struct arg_struct *args = malloc(sizeof(struct arg_struct));

And pass this arguments like this:

pthread_create(&tr, NULL, print_the_arguments, (void *)args);

Don't forget free args! ;)

Sometimes it happened to me that the method described in the accepted answer didn't work, especially if the separator is a carriage return.
In those cases I solved in this way:

string='first line
second line
third line'

oldIFS="$IFS"
IFS='
'
IFS=${IFS:0:1} # this is useful to format your code with tabs
lines=( $string )
IFS="$oldIFS"

for line in "${lines[@]}"
    do
        echo "--> $line"
done

It's not a better idea to override the core.common file of codeigniter. Because that's the more tested and system files....

I make a solution for this problem. In your ckeditor_helper.php file line- 65

if($k !== end (array_keys($data['config']))) {
       $return .= ",";
}

Change this to-->

 $segment = array_keys($data['config']);
    if($k !== end($segment)) {
           $return .= ",";
    }

I think this is the best solution and then your problem notice will dissappear.

                              'GET'
                         )

[Update]

Some of these answers are old. Today I would use the requests module like the answer by robaple.

Imagine an 8 digit padding function that transforms:

• '123asd' -> '00000123asd'
• '19asd' -> '00000019asd'

We can used the padded strings to help us sort '19asd' to appear before '123asd'.

Use the regular expression /\d+/g to help find all the numbers that need to be padded:

str.replace(/\d+/g, pad)

The following demonstrates sorting using this technique:

var list = [_x000D_
    '123asd',_x000D_
    '19asd',_x000D_
    '12345asd',_x000D_
    'asd123',_x000D_
    'asd12'_x000D_
];_x000D_
_x000D_
function pad(n) { return ("00000000" + n).substr(-8); }_x000D_
function natural_expand(a) { return a.replace(/\d+/g, pad) };_x000D_
function natural_compare(a, b) {_x000D_
    return natural_expand(a).localeCompare(natural_expand(b));_x000D_
}_x000D_
_x000D_
console.log(list.map(natural_expand).sort()); // intermediate values_x000D_
console.log(list.sort(natural_compare)); // result

The intermediate results show what the natural_expand() routine does and gives you an understanding of how the subsequent natural_compare routine will work:

[
  "00000019asd",
  "00000123asd",
  "00012345asd",
  "asd00000012",
  "asd00000123"
]

Outputs:

[
  "19asd",
  "123asd",
  "12345asd",
  "asd12",
  "asd123"
]

Add a trigger in database:

DELIMITER //
CREATE TRIGGER update_user_password 
  BEFORE UPDATE ON users
  FOR EACH ROW
    BEGIN
      IF OLD.password <> NEW.password THEN
        SET NEW.password_changed_on = NOW();
      END IF;
    END //
DELIMITER ;

The password changed time will update only when password column is changed.

Here is @Vitaliy Gozhenko's answer, in Swift.
To summarize you will create a UITableViewHeaderFooterView that contains a UITableViewCell. This UITableViewCell will be "dequeuable" and you can design it in your storyboard.

1. Create a UITableViewHeaderFooterView class

   class CustomHeaderFooterView: UITableViewHeaderFooterView {
   var cell : UITableViewCell? {
       willSet {
           cell?.removeFromSuperview()
       }
       didSet {
           if let cell = cell {
               cell.frame = self.bounds
               cell.autoresizingMask = [UIViewAutoresizing.FlexibleHeight, UIViewAutoresizing.FlexibleWidth]
               self.contentView.backgroundColor = UIColor .clearColor()
               self.contentView .addSubview(cell)
           }
       }
   }
   

2. Plug your tableview with this class in your viewDidLoad function:

   self.tableView.registerClass(CustomHeaderFooterView.self, forHeaderFooterViewReuseIdentifier: "SECTION_ID")
   

3. When asking, for a section header, dequeue a CustomHeaderFooterView, and insert a cell into it

   func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
       let view = self.tableView.dequeueReusableHeaderFooterViewWithIdentifier("SECTION_ID") as! CustomHeaderFooterView
       if view.cell == nil {
           let cell = self.tableView.dequeueReusableCellWithIdentifier("Cell")
           view.cell = cell;
       }
   
       // Fill the cell with data here
   
       return view;
   }
   

The latest Java Web Start has been enhanced to allow good offline operation as well as allowing "local installation". It is worth looking into.

EDIT 2018: Java Web Start is no longer bundled with the newest JDK's. Oracle is pushing towards a "deploy your app locally with an enclosed JRE" model instead.

I realize this question is old, but it recently popped up in a search I just ran, so I thought I'd post an alternative to the above answer.

If you are looking to generate create scripts programmatically in .Net, I would highly recommend looking into Server Management Objects (SMO) or Distributed Management Objects (DMO) -- depending on which version of SQL Server you are using (the former is 2005+, the latter 2000). Using these libraries, scripting a table is as easy as:

Server server      = new Server(".");
Database northwind = server.Databases["Northwind"];
Table categories   = northwind.Tables["Categories"];

StringCollection script = categories.Script();
string[] scriptArray    = new string[script.Count];

script.CopyTo(scriptArray, 0);

Here is a blog post with more information.

Temp tables are always on disk - so as long as your CTE can be held in memory, it would most likely be faster (like a table variable, too).

But then again, if the data load of your CTE (or temp table variable) gets too big, it'll be stored on disk, too, so there's no big benefit.

In general, I prefer a CTE over a temp table since it's gone after I used it. I don't need to think about dropping it explicitly or anything.

So, no clear answer in the end, but personally, I would prefer CTE over temp tables.

Here is the example:

var charCode = "a".charCodeAt(0);_x000D_
console.log(charCode);

Or if you have longer strings:

var string = "Some string";_x000D_
_x000D_
for (var i = 0; i < string.length; i++) {_x000D_
  console.log(string.charCodeAt(i));_x000D_
}

String.charCodeAt(x) method will return ASCII character code at a given position.

I think, testing variables for values you do not expect is not a good idea in general. Because the test as your you can consider as writing a blacklist of forbidden values. But what if you forget to list all the forbidden values? Someone, even you, can crack your code with passing an unexpected value. So a more appropriate approach is something like whitelisting - testing variables only for the expected values, not unexpected. For example, if you expect the data value to be a string, instead of this:

function (data) {
  if (data != null && data !== undefined) {
    // some code here
    // but what if data === false?
    // or data === '' - empty string?
  }
}

do something like this:

function (data) {
  if (typeof data === 'string' && data.length) {
    // consume string here, it is here for sure
    // cleaner, it is obvious what type you expect
    // safer, less error prone due to implicit coercion
  } 
}

String[] array = new String[items2.size()];
items2.toArray(array);

Since the add-ons don't work anymore, the most helpful set of tools I've found is using Visual Studio/IE because you can set breakpoints in your JS and inspect your data that way. Of course Chrome and Firefox have much better dev tools in general. Also, good ol' console.log() has been super helpful!

you need the set key and value in foreach loop for that:

foreach($item AS $key -> $value) {
echo $value;
}

this should do the trick :)

Adding this in case it helps someone.

As I am working with Japanese characters, encoding has also been set appropriately. However, from time to time, I find that htmlentities and htmlspecialchars are not sufficient.

Some user inputs contain special characters that are not stripped by the above functions. In those cases I have to do this:

preg_replace('/[\x00-\x1f]/','',htmlspecialchars($string))

This will also remove certain xml-unsafe control characters like Null character or EOT. You can use this table to determine which characters you wish to omit.

You're very close. What you need to remember is when you're calling a method from another class you need to tell the compiler where to find that method.

So, instead of simply calling addWord("someWord"), you will need to initialise an instance of the WordList class (e.g. WordList list = new WordList();), and then call the method using that (i.e. list.addWord("someWord");.

However, your code at the moment will still throw an error there, because that would be trying to call a non-static method from a static one. So, you could either make addWord() static, or change the methods in the Words class so that they're not static.

My bad with the above paragraph - however you might want to reconsider ProcessInput() being a static method - does it really need to be?

sum.up is not a valid keyword argument name. Keyword arguments must be valid identifiers. You should look in the documentation of the library you are using how this argument really is called – maybe sum_up?

Make sure you are not using the same element Id / class elsewhere, for an element unrelated to the modal component.

That is.. if you are identifying your buttons which trigger the modal popups using the class name 'myModal', ensure that there are no unrelated elements having that same class name.

text='Python' searches for elements that have the exact text you provided:

import re
from BeautifulSoup import BeautifulSoup

html = """<p>exact text</p>
   <p>almost exact text</p>"""
soup = BeautifulSoup(html)
print soup(text='exact text')
print soup(text=re.compile('exact text'))

Output

[u'exact text']
[u'exact text', u'almost exact text']

"To see if the string 'Python' is located on the page http://python.org":

import urllib2
html = urllib2.urlopen('http://python.org').read()
print 'Python' in html # -> True

If you need to find a position of substring within a string you could do html.find('Python').

Since you're talking about financial figures, you DO NOT WANT to use floating-point arithmetic. You're better off using Decimal.

>>> from decimal import Decimal
>>> Decimal("33.505")
Decimal('33.505')

Text output formatting with new-style format() (defaults to half-even rounding):

>>> print("financial return of outcome 1 = {:.2f}".format(Decimal("33.505")))
financial return of outcome 1 = 33.50
>>> print("financial return of outcome 1 = {:.2f}".format(Decimal("33.515")))
financial return of outcome 1 = 33.52

See the differences in rounding due to floating-point imprecision:

>>> round(33.505, 2)
33.51
>>> round(Decimal("33.505"), 2)  # This converts back to float (wrong)
33.51
>>> Decimal(33.505)  # Don't init Decimal from floating-point
Decimal('33.50500000000000255795384873636066913604736328125')

Proper way to round financial values:

>>> Decimal("33.505").quantize(Decimal("0.01"))  # Half-even rounding by default
Decimal('33.50')

It is also common to have other types of rounding in different transactions:

>>> import decimal
>>> Decimal("33.505").quantize(Decimal("0.01"), decimal.ROUND_HALF_DOWN)
Decimal('33.50')
>>> Decimal("33.505").quantize(Decimal("0.01"), decimal.ROUND_HALF_UP)
Decimal('33.51')

Remember that if you're simulating return outcome, you possibly will have to round at each interest period, since you can't pay/receive cent fractions, nor receive interest over cent fractions. For simulations it's pretty common to just use floating-point due to inherent uncertainties, but if doing so, always remember that the error is there. As such, even fixed-interest investments might differ a bit in returns because of this.

For this issue, Use JQuery and other js same as you are using in Web Page. However, Electron has node integration so it will not find your js objects. You have to set module = undefined until your js objects are loaded properly. See below example

<!-- Insert this line above local script tags  -->
<script>if (typeof module === 'object') {window.module = module; module = 
undefined;}</script>

<!-- normal script imports etc  -->

After importing like given, you will be able to use the JQuery and other things in electron.

You can do it like this, and no need to dedicate variable:

Toolbar toolbar = findViewById(R.id.toolbar);
Menu menu = toolbar.getMenu();
MenuItem menuItem = menu.findItem(R.id.some_action);
menuItem.setTitle("New title");

Or a little simplified:

MenuItem menuItem = ((Toolbar)findViewById(R.id.toolbar)).getMenu().findItem(R.id.some_action);
menuItem.setTitle("New title");

It works only - after the menu created.

Just searched for the docs, and found this:

Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:

{# returns true #}

{{ 1 in [1, 2, 3] }}

{{ 'cd' in 'abcde' }}

A way of producing a data.frame and being able to do this in one line is to coerce all matrices/data frames passed to cbind into a data.frame while setting the column names attribute using setNames:

a = matrix(rnorm(10), ncol = 2)
b = matrix(runif(10), ncol = 2)

cbind(setNames(data.frame(a), c('n1', 'n2')), 
      setNames(data.frame(b), c('u1', 'u2')))

which produces:

          n1        n2         u1        u2
1 -0.2731750 0.5030773 0.01538194 0.3775269
2  0.5177542 0.6550924 0.04871646 0.4683186
3 -1.1419802 1.0896945 0.57212043 0.9317578
4  0.6965895 1.6973815 0.36124709 0.2882133
5  0.9062591 1.0625280 0.28034347 0.7517128

Unfortunately, there is no setColNames function analogous to setNames for data frames that returns the matrix after the column names, however, there is nothing to stop you from adapting the code of setNames to produce one:

setColNames <- function (object = nm, nm) {
    colnames(object) <- nm
    object
}

See this answer, the magrittr package contains functions for this.

The easiest way is to import the certificate into a sample firefox-profile and then copy the cert8.db to the users you want equip with the certificate.

First import the certificate by hand into the firefox profile of the sample-user. Then copy

• /home/${USER}/.mozilla/firefox/${randomalphanum}.default/cert8.db (Linux/Unix)

• %userprofile%\Application Data\Mozilla\Firefox\Profiles\%randomalphanum%.default\cert8.db (Windows)

into the users firefox-profiles. That's it. If you want to make sure, that new users get the certificate automatically, copy cert8.db to:

• /etc/firefox-3.0/profile (Linux/Unix)

• %programfiles%\firefox-installation-folder\defaults\profile (Windows)

To add on to what Noel M stated, you can look at this question, and this answer shows that the constant is reused.

String constant are always "interned" so there is not really a need for such constant.

String s=""; String t=""; boolean b=s==t; // true

Use set_index with stack for MultiIndex Series, then for DataFrame add reset_index with rename:

df1 = (df.set_index(["location", "name"])
         .stack()
         .reset_index(name='Value')
         .rename(columns={'level_2':'Date'}))
print (df1)
  location  name        Date  Value
0        A  test    Jan-2010     12
1        A  test    Feb-2010     20
2        A  test  March-2010     30
3        B   foo    Jan-2010     18
4        B   foo    Feb-2010     20
5        B   foo  March-2010     25

If you would like to use autocomplete all the time without having to worry about hitting Ctrl + Spacebar or your own keyboard shortcut, you can make the following adjustment in the Eclipse preferences to trigger autocomplete simply by typing several different characters:

1. Eclipse > Preferences > Java > Editor > Content Assist
2. Auto Activation > Auto activation triggers for Java
3. Enter all the characters you want to trigger autocomplete, such as the following:

abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ._

Now any time that you type any of these characters, Eclipse will trigger autocomplete suggestions based on the context.

While Arvin Amir's answer comes close to a full one-line solution you can drop in anywhere; he's got a slight bug in his select statement (missing the end of the line), and I wanted to handle the most common character references.

What I ended up doing was this:

SELECT replace(replace(replace(CAST(CAST(replace([columnNameHere], '&', '&') as xml).query('for $x in //. return concat((($x)//text())[1]," ")') as varchar(max)), '&', '&'), ' ', ' '), ' ', ' ')
FROM [tableName]

Without the character reference code it can be simplified to this:

SELECT CAST(CAST([columnNameHere] as xml).query('for $x in //. return concat((($x)//text())[1]," ")') as varchar(max))
FROM [tableName]

Before understanding next, you need to have a little idea of Request-Response cycle in node though not much in detail. It starts with you making an HTTP request for a particular resource and it ends when you send a response back to the user i.e. when you encounter something like res.send(‘Hello World’);

let’s have a look at a very simple example.

app.get('/hello', function (req, res, next) {
  res.send('USER')
})

Here we do not need next(), because resp.send will end the cycle and hand over the control back to the route middleware.

Now let’s take a look at another example.

app.get('/hello', function (req, res, next) {
  res.send("Hello World !!!!");
});

app.get('/hello', function (req, res, next) {
  res.send("Hello Planet !!!!");
});

Here we have 2 middleware functions for the same path. But you always gonna get the response from the first one. Because that is mounted first in the middleware stack and res.send will end the cycle.

But what if we always do not want the “Hello World !!!!” response back. For some conditions we may want the "Hello Planet !!!!" response. Let’s modify the above code and see what happens.

app.get('/hello', function (req, res, next) {
  if(some condition){
    next();
    return;
  }
  res.send("Hello World !!!!");  
});

app.get('/hello', function (req, res, next) {
  res.send("Hello Planet !!!!");
});

What’s the next doing here. And yes you might have gusses. It’s gonna skip the first middleware function if the condition is true and invoke the next middleware function and you will have the "Hello Planet !!!!" response.

So, next pass the control to the next function in the middleware stack.

What if the first middleware function does not send back any response but do execute a piece of logic and then you get the response back from second middleware function.

Something like below:-

app.get('/hello', function (req, res, next) {
  // Your piece of logic
  next();
});

app.get('/hello', function (req, res, next) {
  res.send("Hello !!!!");
});

In this case you need both the middleware functions to be invoked. So, the only way you reach the second middleware function is by calling next();

What if you do not make a call to next. Do not expect the second middleware function to get invoked automatically. After invoking the first function your request will be left hanging. The second function will never get invoked and you will not get back the response.

Your local port 443 / 8181 / 3820 is used.

If you are on linux/unix:

• use netstat -an and lsof -n to check who is using this port

If you are on windows

• use netstat -an and tcpview to check.

Those two parameters (or variants of) are sent, by convention, with all events.

• sender: The object which has raised the event
• e an instance of EventArgs including, in many cases, an object which inherits from EventArgs. Contains additional information about the event, and sometimes provides ability for code handling the event to alter the event somehow.

In the case of the events you mentioned, neither parameter is particularly useful. The is only ever one page raising the events, and the EventArgs are Empty as there is no further information about the event.

Looking at the 2 parameters separately, here are some examples where they are useful.

sender

Say you have multiple buttons on a form. These buttons could contain a Tag describing what clicking them should do. You could handle all the Click events with the same handler, and depending on the sender do something different

private void HandleButtonClick(object sender, EventArgs e)
{
    Button btn = (Button)sender;
    if(btn.Tag == "Hello")
      MessageBox.Show("Hello")
    else if(btn.Tag == "Goodbye")
       Application.Exit();
    // etc.
}

Disclaimer : That's a contrived example; don't do that!

e

Some events are cancelable. They send CancelEventArgs instead of EventArgs. This object adds a simple boolean property Cancel on the event args. Code handling this event can cancel the event:

private void HandleCancellableEvent(object sender, CancelEventArgs e)
{
    if(/* some condition*/)
    {
       // Cancel this event
       e.Cancel = true;
    }
}

There is one more hint that not in this conversation. for asp.net core 3.1 first add the key that you need to put it in the header, something like this:

Response.Headers.Add("your-key-to-use-it-axios", "your-value");

where you define the cors policy (normaly is in Startup.cs) you should add this key to WithExposedHeaders like this.

          services.AddCors(options =>
        {
        options.AddPolicy("CorsPolicy",
            builder => builder
                .AllowAnyHeader()
                .AllowAnyMethod()
                .AllowAnyOrigin()
                .WithExposedHeaders("your-key-to-use-it-axios"));
        });
    }

you can add all the keys here. now in your client side you can easily access to the your-key-to-use-it-axios by using the response result.

          localStorage.setItem("your-key", response.headers["your-key-to-use-it-axios"]);

you can after use it in all the client side by accessing to it like this:

const jwt = localStorage.getItem("your-key")

ALTER TABLE tablename

I believe that the dates have to be specified in the current culture of the application. You might want to experiment with setting CultureInvariantValues to true and see if that solves your problem. Otherwise you may need to change the DateTimeFormat for the current culture (or the culture itself) to get what you want.

Actually, there are no examples at all. Here is my working code. Recording is triggered by the user pressing a button on the navBar. The recording uses cd quality (44100 samples), stereo (2 channels) linear pcm. Beware: if you want to use a different format, especially an encoded one, make sure you fully understand how to set the AVAudioRecorder settings (read carefully the audio types documentation), otherwise you will never be able to initialize it correctly. One more thing. In the code, I am not showing how to handle metering data, but you can figure it out easily. Finally, note that the AVAudioRecorder method deleteRecording as of this writing crashes your application. This is why I am removing the recorded file through the File Manager. When recording is done, I save the recorded audio as NSData in the currently edited object using KVC.

Add this to your dialog declaration

my: "center",
at: "center",
of: window

Example :

$("#dialog").dialog({
       autoOpen: false,
        height: "auto",
        width: "auto",
        modal: true,
        position: {
            my: "center",
            at: "center",
            of: window
        }
})

With JavaScript 1.6 / ECMAScript 5 you can use the native filter method of an Array in the following way to get an array with unique values:

function onlyUnique(value, index, self) {
  return self.indexOf(value) === index;
}

// usage example:
var a = ['a', 1, 'a', 2, '1'];
var unique = a.filter(onlyUnique);

console.log(unique); // ['a', 1, 2, '1']

The native method filter will loop through the array and leave only those entries that pass the given callback function onlyUnique.

onlyUnique checks, if the given value is the first occurring. If not, it must be a duplicate and will not be copied.

This solution works without any extra library like jQuery or prototype.js.

It works for arrays with mixed value types too.

For old Browsers (<ie9), that do not support the native methods filter and indexOf you can find work arounds in the MDN documentation for filter and indexOf.

If you want to keep the last occurrence of a value, simple replace indexOf by lastIndexOf.

With ES6 it could be shorten to this:

// usage example:
var myArray = ['a', 1, 'a', 2, '1'];
var unique = myArray.filter((v, i, a) => a.indexOf(v) === i);

console.log(unique); // unique is ['a', 1, 2, '1']

Thanks to Camilo Martin for hint in comment.

ES6 has a native object Set to store unique values. To get an array with unique values you could do now this:

var myArray = ['a', 1, 'a', 2, '1'];

let unique = [...new Set(myArray)];

console.log(unique); // unique is ['a', 1, 2, '1']

The constructor of Set takes an iterable object, like Array, and the spread operator ... transform the set back into an Array. Thanks to Lukas Liese for hint in comment.

If you really need clean all of your branches, try

git branch -d $(git branch)

It will delete all your local merged branches except the one you're currently checking in.

It's a good way to make your local clean

You can use Nested MemberwiseClone to do a deep copy. Its almost the same speed as copying a value struct, and its an order of magnitude faster than (a) reflection or (b) serialization (as described in other answers on this page).

Note that if you use Nested MemberwiseClone for a deep copy, you have to manually implement a ShallowCopy for each nested level in the class, and a DeepCopy which calls all said ShallowCopy methods to create a complete clone. This is simple: only a few lines in total, see the demo code below.

Here is the output of the code showing the relative performance difference (4.77 seconds for deep nested MemberwiseCopy vs. 39.93 seconds for Serialization). Using nested MemberwiseCopy is almost as fast as copying a struct, and copying a struct is pretty darn close to the theoretical maximum speed .NET is capable of, which is probably quite close to the speed of the same thing in C or C++ (but would have to run some equivalent benchmarks to check this claim).

    Demo of shallow and deep copy, using classes and MemberwiseClone:
      Create Bob
        Bob.Age=30, Bob.Purchase.Description=Lamborghini
      Clone Bob >> BobsSon
      Adjust BobsSon details
        BobsSon.Age=2, BobsSon.Purchase.Description=Toy car
      Proof of deep copy: If BobsSon is a true clone, then adjusting BobsSon details will not affect Bob:
        Bob.Age=30, Bob.Purchase.Description=Lamborghini
      Elapsed time: 00:00:04.7795670,30000000
    Demo of shallow and deep copy, using structs and value copying:
      Create Bob
        Bob.Age=30, Bob.Purchase.Description=Lamborghini
      Clone Bob >> BobsSon
      Adjust BobsSon details:
        BobsSon.Age=2, BobsSon.Purchase.Description=Toy car
      Proof of deep copy: If BobsSon is a true clone, then adjusting BobsSon details will not affect Bob:
        Bob.Age=30, Bob.Purchase.Description=Lamborghini
      Elapsed time: 00:00:01.0875454,30000000
    Demo of deep copy, using class and serialize/deserialize:
      Elapsed time: 00:00:39.9339425,30000000

To understand how to do a deep copy using MemberwiseCopy, here is the demo project:

// Nested MemberwiseClone example. 
// Added to demo how to deep copy a reference class.
[Serializable] // Not required if using MemberwiseClone, only used for speed comparison using serialization.
public class Person
{
    public Person(int age, string description)
    {
        this.Age = age;
        this.Purchase.Description = description;
    }
    [Serializable] // Not required if using MemberwiseClone
    public class PurchaseType
    {
        public string Description;
        public PurchaseType ShallowCopy()
        {
            return (PurchaseType)this.MemberwiseClone();
        }
    }
    public PurchaseType Purchase = new PurchaseType();
    public int Age;
    // Add this if using nested MemberwiseClone.
    // This is a class, which is a reference type, so cloning is more difficult.
    public Person ShallowCopy()
    {
        return (Person)this.MemberwiseClone();
    }
    // Add this if using nested MemberwiseClone.
    // This is a class, which is a reference type, so cloning is more difficult.
    public Person DeepCopy()
    {
            // Clone the root ...
        Person other = (Person) this.MemberwiseClone();
            // ... then clone the nested class.
        other.Purchase = this.Purchase.ShallowCopy();
        return other;
    }
}
// Added to demo how to copy a value struct (this is easy - a deep copy happens by default)
public struct PersonStruct
{
    public PersonStruct(int age, string description)
    {
        this.Age = age;
        this.Purchase.Description = description;
    }
    public struct PurchaseType
    {
        public string Description;
    }
    public PurchaseType Purchase;
    public int Age;
    // This is a struct, which is a value type, so everything is a clone by default.
    public PersonStruct ShallowCopy()
    {
        return (PersonStruct)this;
    }
    // This is a struct, which is a value type, so everything is a clone by default.
    public PersonStruct DeepCopy()
    {
        return (PersonStruct)this;
    }
}
// Added only for a speed comparison.
public class MyDeepCopy
{
    public static T DeepCopy<T>(T obj)
    {
        object result = null;
        using (var ms = new MemoryStream())
        {
            var formatter = new BinaryFormatter();
            formatter.Serialize(ms, obj);
            ms.Position = 0;
            result = (T)formatter.Deserialize(ms);
            ms.Close();
        }
        return (T)result;
    }
}

Then, call the demo from main:

    void MyMain(string[] args)
    {
        {
            Console.Write("Demo of shallow and deep copy, using classes and MemberwiseCopy:\n");

Again, note that if you use Nested MemberwiseClone for a deep copy, you have to manually implement a ShallowCopy for each nested level in the class, and a DeepCopy which calls all said ShallowCopy methods to create a complete clone. This is simple: only a few lines in total, see the demo code above.

Note that when it comes to cloning an object, there is is a big difference between a "struct" and a "class":

• If you have a "struct", it's a value type so you can just copy it, and the contents will be cloned.
• If you have a "class", it's a reference type, so if you copy it, all you are doing is copying the pointer to it. To create a true clone, you have to be more creative, and use a method which creates another copy of the original object in memory.
• Cloning objects incorrectly can lead to very difficult-to-pin-down bugs. In production code, I tend to implement a checksum to double check that the object has been cloned properly, and hasn't been corrupted by another reference to it. This checksum can be switched off in Release mode.
• I find this method quite useful: often, you only want to clone parts of the object, not the entire thing. It's also essential for any use case where you are modifying objects, then feeding the modified copies into a queue.

Update

It's probably possible to use reflection to recursively walk through the object graph to do a deep copy. WCF uses this technique to serialize an object, including all of its children. The trick is to annotate all of the child objects with an attribute that makes it discoverable. You might lose some performance benefits, however.

Update

Quote on independent speed test (see comments below):

I've run my own speed test using Neil's serialize/deserialize extension method, Contango's Nested MemberwiseClone, Alex Burtsev's reflection-based extension method and AutoMapper, 1 million times each. Serialize-deserialize was slowest, taking 15.7 seconds. Then came AutoMapper, taking 10.1 seconds. Much faster was the reflection-based method which took 2.4 seconds. By far the fastest was Nested MemberwiseClone, taking 0.1 seconds. Comes down to performance versus hassle of adding code to each class to clone it. If performance isn't an issue go with Alex Burtsev's method. – Simon Tewsi

Parentheses in function definition

Parentheses () are being used in function definition:

function_name () { command1 ; command2 ; }

That is the reason you have to escape parentheses even in command parameters:

$ echo (
bash: syntax error near unexpected token `newline'

$ echo \(
(

$ echo () { command echo The command echo was redefined. ; }
$ echo anything
The command echo was redefined.

You can create an extension method similar to ToDictionary() with the difference being that it allows duplicates. Something like:

    public static Dictionary<TKey, TElement> SafeToDictionary<TSource, TKey, TElement>(
        this IEnumerable<TSource> source, 
        Func<TSource, TKey> keySelector, 
        Func<TSource, TElement> elementSelector, 
        IEqualityComparer<TKey> comparer = null)
    {
        var dictionary = new Dictionary<TKey, TElement>(comparer);

        if (source == null)
        {
            return dictionary;
        }

        foreach (TSource element in source)
        {
            dictionary[keySelector(element)] = elementSelector(element);
        }

        return dictionary; 
    }

In this case, if there are duplicates, then the last value wins.

In XML

android:textStyle="bold" //only bold
android:textStyle="italic" //only italic
android:textStyle="bold|italic" //bold & italic

You can only use specific fonts sans, serif & monospace via xml, Java code can use custom fonts

android:typeface="monospace" // or sans or serif

Programmatically (Java code)

TextView textView = (TextView) findViewById(R.id.TextView1);

textView.setTypeface(Typeface.SANS_SERIF); //only font style
textView.setTypeface(null,Typeface.BOLD); //only text style(only bold)
textView.setTypeface(null,Typeface.BOLD_ITALIC); //only text style(bold & italic)
textView.setTypeface(Typeface.SANS_SERIF,Typeface.BOLD); 
                                         //font style & text style(only bold)
textView.setTypeface(Typeface.SANS_SERIF,Typeface.BOLD_ITALIC);
                                         //font style & text style(bold & italic)

If you use the Geolocation API, it would be as simple as using the following code.

navigator.geolocation.getCurrentPosition(function(location) {
  console.log(location.coords.latitude);
  console.log(location.coords.longitude);
  console.log(location.coords.accuracy);
});

You may also be able to use Google's Client Location API.

Any answer did not cover if you need to add a PHP page outside of the WordPress Theme. This is the way.

You need to include wp-load.php.

<?php require_once('wp-load.php'); ?>

Then you can use any WordPress function on that page.

cvc-elt.1: Cannot find the declaration of element 'Root'. [7]

Your schemaLocation attribute on the root element should be xsi:schemaLocation, and you need to fix it to use the right namespace.

You should probably change the targetNamespace of the schema and the xmlns of the document to http://myNameSpace.com (since namespaces are supposed to be valid URIs, which Test.Namespace isn't, though urn:Test.Namespace would be ok). Once you do that it should find the schema. The point is that all three of the schema's target namespace, the document's namespace, and the namespace for which you're giving the schema location must be the same.

(though it still won't validate as your <element2> contains an <element3> in the document where the schema expects item)

Have you considered just doing whatever you want to do in the if rather than looking before you leap?

I.e., if you want to check for the existence of a directory before you enter it, try just doing this:

if pushd /path/you/want/to/enter; then
    # Commands you want to run in this directory
    popd
fi

If the path you give to pushd exists, you'll enter it and it'll exit with 0, which means the then portion of the statement will execute. If it doesn't exist, nothing will happen (other than some output saying the directory doesn't exist, which is probably a helpful side-effect anyways for debugging).

It seems better than this, which requires repeating yourself:

if [ -d /path/you/want/to/enter ]; then
    pushd /path/you/want/to/enter
    # Commands you want to run in this directory
    popd
fi

The same thing works with cd, mv, rm, etc... if you try them on files that don't exist, they'll exit with an error and print a message saying it doesn't exist, and your then block will be skipped. If you try them on files that do exist, the command will execute and exit with a status of 0, allowing your then block to execute.

flush(); Flushing is the process of synchronizing the underlying persistent store with persistable state held in memory. It will update or insert into your tables in the running transaction, but it may not commit those changes.

You need to flush in batch processing otherwise it may give OutOfMemoryException.

Commit(); Commit will make the database commit. When you have a persisted object and you change a value on it, it becomes dirty and hibernate needs to flush these changes to your persistence layer. So, you should commit but it also ends the unit of work (transaction.commit()).

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

You can get to SIZES by means of self.SIZES (in an instance method) or cls.SIZES (in a class method).

In any case, you will have to be explicit about where to find SIZES. An alternative is to put SIZES in the module containing the classes, but then you need to define all classes in a single module.

System.out.println(Integer.toBinaryString(343));

__FUNCTION__ is non standard, __func__ exists in C99 / C++11. The others (__LINE__ and __FILE__) are just fine.

It will always report the right file and line (and function if you choose to use __FUNCTION__/__func__). Optimization is a non-factor since it is a compile time macro expansion; it will never affect performance in any way.

An example of use :

You consume many classes that have a commun property 'CreationDate' :

public class Contact
{
    // some properties

    public DateTime CreationDate { get; set; }        
}

public class Company
{
    // some properties

    public DateTime CreationDate { get; set; }

}

public class Opportunity
{
    // some properties

    public DateTime CreationDate { get; set; }

}

If you write a commun method that retrieves the value of the 'CreationDate' Property, you'd have to use reflection:

    static DateTime RetrieveValueOfCreationDate(Object item)
    {
        return (DateTime)item.GetType().GetProperty("CreationDate").GetValue(item);
    }

With the 'dynamic' concept, your code is much more elegant :

    static DateTime RetrieveValueOfCreationDate(dynamic item)
    {
        return item.CreationDate;
    }

Assuming you're using a std::ofstream to write to file, the following snippet will write a std::string to file in human readable form:

std::ofstream file("filename");
std::string my_string = "Hello text in file\n";
file << my_string;

From PHP using single quotes for the line break worked for me to support the line breaks when I pass that var to an HTML text area value attribute

PHP

foreach ($videoUrls as $key => $value) {
  $textAreaValue .= $value->video_url . '\n';
}

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

HTML/JS

$( document ).ready(function() {
    var text = "<?= htmlspecialchars($textAreaValue); ?>";
    document.getElementById("video_urls_textarea").value = text;
});

If you are using SqlServer the distinct keyword should work for you. (Not sure about other databases)

declare @t table (a int , b int)

insert into @t (a,b) select 1, 1
insert into @t (a,b) select 1, 2
insert into @t (a,b) select 1, 1

select distinct * from @t

results in

a b
1 1
1 2

Using iconv looks like best solution but i my case I have Notice form this function: "Detected an illegal character in input string in" (without igonore). I use 2 functions to manipulate ASCII strings convert it to array of ASCII code and then serialize:

public static function ToAscii($string) {
    $strlen = strlen($string);
    $charCode = array();
    for ($i = 0; $i < $strlen; $i++) {
        $charCode[] = ord(substr($string, $i, 1));
    }
    $result = json_encode($charCode);
    return $result;
}

public static function fromAscii($string) {
    $charCode = json_decode($string);
    $result = '';
    foreach ($charCode as $code) {
        $result .= chr($code);
    };
    return $result;
}

You don't need express. You don't need connect. Node.js does http NATIVELY. All you need to do is return a file dependent on the request:

var http = require('http')
var url = require('url')
var fs = require('fs')

http.createServer(function (request, response) {
    var requestUrl = url.parse(request.url)    
    response.writeHead(200)
    fs.createReadStream(requestUrl.pathname).pipe(response)  // do NOT use fs's sync methods ANYWHERE on production (e.g readFileSync) 
}).listen(9615)    

A more full example that ensures requests can't access files underneath a base-directory, and does proper error handling:

var http = require('http')
var url = require('url')
var fs = require('fs')
var path = require('path')
var baseDirectory = __dirname   // or whatever base directory you want

var port = 9615

http.createServer(function (request, response) {
    try {
        var requestUrl = url.parse(request.url)

        // need to use path.normalize so people can't access directories underneath baseDirectory
        var fsPath = baseDirectory+path.normalize(requestUrl.pathname)

        var fileStream = fs.createReadStream(fsPath)
        fileStream.pipe(response)
        fileStream.on('open', function() {
             response.writeHead(200)
        })
        fileStream.on('error',function(e) {
             response.writeHead(404)     // assume the file doesn't exist
             response.end()
        })
   } catch(e) {
        response.writeHead(500)
        response.end()     // end the response so browsers don't hang
        console.log(e.stack)
   }
}).listen(port)

console.log("listening on port "+port)

Im coming from react native but I think that this applies to this question as well. To specify.

Within the file android/app/build.gradle search for applicationId (within android, defaultConfig)

and ensure that that value is the same this

client[0]client_info.android_client_info.package_name

as the value within google-services.json.

Other option, for similar example but with anidated selects, think that you have two select, the name of the first is "ea_pub_dest" and the name of the second is "ea_pub_dest_2", ok, now take the event click of the first and display the second.

<script>

function test()
{
    value = document.getElementById("ea_pub_dest").value;
    if ( valor == "value_1" )
        document.getElementById("ea_pub_dest_nivel").style.display = "block";
}
</script>

You could also use GDAL to do this. I realize that it is a geospatial toolkit, but nothing requires you to have a cartographic product.

Link to precompiled GDAL binaries for windows (assuming windows here) http://www.gisinternals.com/sdk/

To access the array:

from osgeo import gdal

dataset = gdal.Open("path/to/dataset.tiff", gdal.GA_ReadOnly)
for x in range(1, dataset.RasterCount + 1):
    band = dataset.GetRasterBand(x)
    array = band.ReadAsArray()

Found the problem.

The standard metadata string looks like this:

metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl

And this works fine in most cases. However, in some (including mine) Entity Framework get confused and does not know which dll to look in. Therefore, change the metadata string to:

metadata=res://nameOfDll/Model.csdl|res://nameOfDll/Model.ssdl|res://nameOfDll/Model.msl

And it will work. It was this link that got me on the right track:

http://itstu.blogspot.com/2008/07/to-load-specified-metadata-resource.html

Although I had the oposite problem, did not work in unit test, but worked in service.

Much of the reason that it took > 48 hours to do your inserts is because of your indexes. It is incredibly faster to:

1 - Drop all indexes 2 - Do all inserts 3 - Create indexes again

How can we read data from a text file and store in a String Variable?

Err, read data from the file and store it in a String variable. It's just code. Not a real question so far.

Is it possible to pass the filename in a method and it would return the String which is the text from the file.

Yes it's possible. It's also a very bad idea. You should deal with the file a part at a time, for example a line at a time. Reading the entire file into memory before you process any of it adds latency; wastes memory; and assumes that the entire file will fit into memory. One day it won't. You don't want to do it this way.

With Eloquent its very easy to retrieve relational data. Checkout the following example with your scenario in Laravel 5.

We have three models:

1) Article (belongs to user and category)

2) Category (has many articles)

3) User (has many articles)

1) Article.php

<?php

namespace App\Models;
 use Eloquent;

class Article extends Eloquent{

    protected $table = 'articles';

    public function user()
    {
        return $this->belongsTo('App\Models\User');
    }

    public function category()
    {
        return $this->belongsTo('App\Models\Category');
    }

}

2) Category.php

<?php

namespace App\Models;

use Eloquent;

class Category extends Eloquent
{
    protected $table = "categories";

    public function articles()
    {
        return $this->hasMany('App\Models\Article');
    }

}

3) User.php

<?php

namespace App\Models;
use Eloquent;

class User extends Eloquent
{
    protected $table = 'users';

    public function articles()
    {
        return $this->hasMany('App\Models\Article');
    }

}

You need to understand your database relation and setup in models. User has many articles. Category has many articles. Articles belong to user and category. Once you setup the relationships in Laravel, it becomes easy to retrieve the related information.

For example, if you want to retrieve an article by using the user and category, you would need to write:

$article = \App\Models\Article::with(['user','category'])->first();

and you can use this like so:

//retrieve user name 
$article->user->user_name  

//retrieve category name 
$article->category->category_name

In another case, you might need to retrieve all the articles within a category, or retrieve all of a specific user`s articles. You can write it like this:

$categories = \App\Models\Category::with('articles')->get();

$users = \App\Models\Category::with('users')->get();

You can learn more at http://laravel.com/docs/5.0/eloquent

Two other ways are strcpy(str, ""); and string[0] = 0

To really delete the Variable contents (in case you have dirty code which is not working properly with the snippets above :P ) use a loop like in the example below.

#include <string.h>

...

int i=0;
for(i=0;i<strlen(string);i++)
{
    string[i] = 0;
}

In case you want to clear a dynamic allocated array of chars from the beginning, you may either use a combination of malloc() and memset() or - and this is way faster - calloc() which does the same thing as malloc but initializing the whole array with Null.

At last i want you to have your runtime in mind. All the way more, if you're handling huge arrays (6 digits and above) you should try to set the first value to Null instead of running memset() through the whole String.

It may look dirtier at first, but is way faster. You just need to pay more attention on your code ;)

I hope this was useful for anybody ;)

The %#08X conversion must precede the value with 0X; that is required by the standard. There's no evidence in the standard that the # should alter the behaviour of the 08 part of the specification except that the 0X prefix is counted as part of the length (so you might want/need to use %#010X. If, like me, you like your hex presented as 0x1234CDEF, then you have to use 0x%08X to achieve the desired result. You could use %#.8X and that should also insert the leading zeroes.

Try variations on the following code:

#include <stdio.h>

int main(void)
{
    int j = 0;
    printf("0x%.8X = %#08X = %#.8X = %#010x\n", j, j, j, j);
    for (int i = 0; i < 8; i++)
    {
        j = (j << 4) | (i + 6);
        printf("0x%.8X = %#08X = %#.8X = %#010x\n", j, j, j, j);
    }
    return(0);
}

On an RHEL 5 machine, and also on Mac OS X (10.7.5), the output was:

0x00000000 = 00000000 = 00000000 = 0000000000
0x00000006 = 0X000006 = 0X00000006 = 0x00000006
0x00000067 = 0X000067 = 0X00000067 = 0x00000067
0x00000678 = 0X000678 = 0X00000678 = 0x00000678
0x00006789 = 0X006789 = 0X00006789 = 0x00006789
0x0006789A = 0X06789A = 0X0006789A = 0x0006789a
0x006789AB = 0X6789AB = 0X006789AB = 0x006789ab
0x06789ABC = 0X6789ABC = 0X06789ABC = 0x06789abc
0x6789ABCD = 0X6789ABCD = 0X6789ABCD = 0x6789abcd

I'm a little surprised at the treatment of 0; I'm not clear why the 0X prefix is omitted, but with two separate systems doing it, it must be standard. It confirms my prejudices against the # option.

The treatment of zero is according to the standard.

ISO/IEC 9899:2011 §7.21.6.1 The fprintf function

¶6 The flag characters and their meanings are:
...
# The result is converted to an "alternative form". ... For x (or X) conversion, a nonzero result has 0x (or 0X) prefixed to it. ...

(Emphasis added.)

Note that using %#X will use upper-case letters for the hex digits and 0X as the prefix; using %#x will use lower-case letters for the hex digits and 0x as the prefix. If you prefer 0x as the prefix and upper-case letters, you have to code the 0x separately: 0x%X. Other format modifiers can be added as needed, of course.

For printing addresses, use the <inttypes.h> header and the uintptr_t type and the PRIXPTR format macro:

#include <inttypes.h>
#include <stdio.h>

int main(void)
{
    void *address = &address;  // &address has type void ** but it converts to void *
    printf("Address 0x%.12" PRIXPTR "\n", (uintptr_t)address);
    return 0;
}

Example output:

Address 0x7FFEE5B29428

Choose your poison on the length — I find that a precision of 12 works well for addresses on a Mac running macOS. Combined with the . to specify the minimum precision (digits), it formats addresses reliably. If you set the precision to 16, the extra 4 digits are always 0 in my experience on the Mac, but there's certainly a case to be made for using 16 instead of 12 in portable 64-bit code (but you'd use 8 for 32-bit code).

From .Net 3.5 you can use LINQ extension method that (sometimes) makes code flow a bit better.

Usage looks like this:

using System.Linq; 

// ...

public void My()
{
    var myArray = new[] { "abc", "123", "zyx" };
    List<string> myList = myArray.ToList();
}

PS. There's also ToArray() method that works in other way.

Actually what Luis proposed did not work for me. I had to figure out another way. This is what helped me. Might help you too. Links:

1. *.getEncoded(): https://docs.oracle.com/javase/7/docs/api/java/security/Key.html

2. Encoder information: https://docs.oracle.com/javase/8/docs/api/java/util/Base64.Encoder.html

3. Decoder information: https://docs.oracle.com/javase/8/docs/api/java/util/Base64.Decoder.html

Code snippets: For encoding:

String temp = new String(Base64.getEncoder().encode(key.getEncoded()));

For decoding:

byte[] encodedKey = Base64.getDecoder().decode(temp);
SecretKey originalKey = new SecretKeySpec(encodedKey, 0, encodedKey.length, "DES");

45 characters.

You might expect an address to be

0000:0000:0000:0000:0000:0000:0000:0000

8 * 4 + 7 = 39

8 groups of 4 digits with 7 : between them.

But if you have an IPv4-mapped IPv6 address, the last two groups can be written in base 10 separated by ., eg. [::ffff:192.168.100.228]. Written out fully:

0000:0000:0000:0000:0000:ffff:192.168.100.228

(6 * 4 + 5) + 1 + (4 * 3 + 3) = 29 + 1 + 15 = 45

Note, this is an input/display convention - it's still a 128 bit address and for storage it would probably be best to standardise on the raw colon separated format, i.e. [0000:0000:0000:0000:0000:ffff:c0a8:64e4] for the address above.

Alternatively, you can use npx which comes along with the npm > 5.6.

npx bower install

Random item selection:

import random

my_list = [1, 2, 3, 4, 5]
num_selections = 2

new_list = random.sample(my_list, num_selections)

To preserve the order of the list, you could do:

randIndex = random.sample(range(len(my_list)), n_selections)
randIndex.sort()
new_list = [my_list[i] for i in randIndex]

All of the answers above break expected browser behavior. What most people want is something that will scroll to the top if it's a "new" page, but return to the previous position if you're getting there through the Back (or Forward) button.

If you assume HTML5 mode, this turns out to be easy (although I'm sure some bright folks out there can figure out how to make this more elegant!):

// Called when browser back/forward used
window.onpopstate = function() { 
    $timeout.cancel(doc_scrolling); 
};

// Called after ui-router changes state (but sadly before onpopstate)
$scope.$on('$stateChangeSuccess', function() {
    doc_scrolling = $timeout( scroll_top, 50 );

// Moves entire browser window to top
scroll_top = function() {
    document.body.scrollTop = document.documentElement.scrollTop = 0;
}

The way it works is that the router assumes it is going to scroll to the top, but delays a bit to give the browser a chance to finish up. If the browser then notifies us that the change was due to a Back/Forward navigation, it cancels the timeout, and the scroll never occurs.

I used raw document commands to scroll because I want to move to the entire top of the window. If you just want your ui-view to scroll, then set autoscroll="my_var" where you control my_var using the techniques above. But I think most people will want to scroll the entire page if you are going to the page as "new".

The above uses ui-router, though you could use ng-route instead by swapping $routeChangeSuccess for$stateChangeSuccess.

Keep in mind that docker ps --size may be an expensive command, taking more than a few minutes to complete. The same applies to container list API requests with size=1. It's better not to run it too often.

Take a look at alternatives we compiled, including the du -hs option for the docker persistent volume directory.

You map your dispatcher on *.do:

<servlet-mapping>
   <servlet-name>Dispatcher</servlet-name>
   <url-pattern>*.do</url-pattern>
</servlet-mapping>

but your controller is mapped on an url without .do:

@RequestMapping("/editPresPage")

Try changing this to:

@RequestMapping("/editPresPage.do")

I think some explanation of Jon's answer would be constructive. The following:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

checks that if the specified file or directory respectively doesn't exist, then the rewrite rule proceeds:

RewriteRule ^(.*)\.html$ /$1 [L,R=301]

But what does that mean? It uses regex (regular expressions). Here is a little something I made earlier...

I think that's correct.

NOTE: When testing your .htaccess do not use 301 redirects. Use 302 until finished testing, as the browser will cache 301s. See https://stackoverflow.com/a/9204355/3217306

Update: I was slightly mistaken, . matches all characters except newlines, so includes whitespace. Also, here is a helpful regex cheat sheet

Sources:

http://community.sitepoint.com/t/what-does-this-mean-rewritecond-request-filename-f-d/2034/2

Another non-allocating alternative: create a singleton, say of class C, as you need it:

singleton<C>()

using

template <class X>
X& singleton()
{
    static X x;
    return x;
}

Neither this nor Catalin's answer is automatically thread-safe in current C++, but will be in C++0x.

1. PM>Uninstall-Package EntityFramework -Force
2. PM>Iinstall-Package EntityFramework -Pre -Version 6.0.0

I solve this problem with this code in NugetPackageConsole.and it works.The problem was in the version. i thikn it will help others.

Full Example (Python 3):
For Python 2.x look into Note below

import re

mylist = ["dog", "cat", "wildcat", "thundercat", "cow", "hooo"]
r = re.compile(".*cat")
newlist = list(filter(r.match, mylist)) # Read Note
print(newlist)

Prints:

['cat', 'wildcat', 'thundercat']

Note:

For Python 2.x developers, filter returns a list already. In Python 3.x filter was changed to return an iterator so it has to be converted to list (in order to see it printed out nicely).

WordPress does not execute PHP in post/page content by default unless it has a shortcode.

The quickest and easiest way to do this is to use a plugin that allows you to run PHP embedded in post content.

There are two other "quick and easy" ways to accomplish it without a plugin:

• Make it a shortcode (put it in functions.php and have it echo the country name) which is very easy - see here: Shortcode API at WP Codex

• Put it in a template file - make a custom template for that page based on your default page template and add the PHP into the template file rather than the post content: Custom Page Templates

I added a modal dialog in jsp and tried to open it with javascript in jsx and hit the same error: "...modal is not a function"

In my case, simply by adding the missing import to the jsx solved the problem.

`import "./../bower/bootstrap/js/modal.js"; // or import ".../bootstrap.min.js"` 

This solution worked for me.

input:focus {
    outline: none !important;
    box-shadow: none !important;
}

The issue is with this line

 xlo.Worksheets(1).Cells(2, 2) = TextBox1.Text

You have the textbox defined at some other location which you are not using here. Excel is unable to find the textbox object in the current sheet while this textbox was defined in xlw.

Hence replace this with

 xlo.Worksheets(1).Cells(2, 2) = worksheets("xlw").TextBox1.Text 

Accepted answer is right, however I had a trouble with that. When I add in my code, checking on debugger, I saw that it changes from

result.replace(/"/g,'"')

to

result.replace(/"/g,'"')

Instead of this I use that:

result.replace(/(&quot\;)/g,"\"")

By this notation it works.

Since you tagged it Rails, you can use truncate:

http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#method-i-truncate

Example:

 truncate(@text, :length => 17)

Excerpt is nice to know too, it lets you display an excerpt of a text Like so:

 excerpt('This is an example', 'an', :radius => 5)
 # => ...s is an exam...

http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#method-i-excerpt

Is one just an extension?

Pretty much, yes - RFC 3339 is listed as a profile of ISO 8601. Most notably RFC 3339 specifies a complete representation of date and time (only fractional seconds are optional). The RFC also has some small, subtle differences. For example truncated representations of years with only two digits are not allowed -- RFC 3339 requires 4-digit years, and the RFC only allows a period character to be used as the decimal point for fractional seconds. The RFC also allows the "T" to be replaced by a space (or other character), while the standard only allows it to be omitted (and only when there is agreement between all parties using the representation).

I wouldn't worry too much about the differences between the two, but on the off-chance your use case runs in to them, it'd be worth your while taking a glance at:

• RFC 3339
• Wikipedia entry on ISO 8601

Since it's an async operation the onreadystatechange may happen before the value has loaded in the responseText, try using a window.setTimeout(function () { JSON.parse(xhr.responseText); }, 1000); to see if the error persists? BOL

You can actually handle all of this with just a simple template tag. See http://jsfiddle.net/m4ve9/ for an example. Note that I actually didn't need a compile or link property on the super-directive definition.

During the compilation process, Angular pulls in the template values before compiling, so you can attach any further directives there and Angular will take care of it for you.

If this is a super directive that needs to preserve the original internal content, you can use transclude : true and replace the inside with <ng-transclude></ng-transclude>

Hope that helps, let me know if anything is unclear

Use str = ""+a+b+c;

Here the first + is String concat, so the result will be a String. Note where the "" lies is important.

Or (maybe) better, use a StringBuilder.

General Solution

We use object-scan for a lot of data processing. It has some nice properties, especially traversing in delete safe order. Here is how one could implement find, delete and replace for your question.

// const objectScan = require('object-scan');

const tool = (() => {
  const scanner = objectScan(['[*]'], {
    abort: true,
    rtn: 'bool',
    filterFn: ({
      value, parent, property, context
    }) => {
      if (value.id === context.id) {
        context.fn({ value, parent, property });
        return true;
      }
      return false;
    }
  });
  return {
    add: (data, id, obj) => scanner(data, { id, fn: ({ parent, property }) => parent.splice(property + 1, 0, obj) }),
    del: (data, id) => scanner(data, { id, fn: ({ parent, property }) => parent.splice(property, 1) }),
    mod: (data, id, prop, v = undefined) => scanner(data, {
      id,
      fn: ({ value }) => {
        if (value !== undefined) {
          value[prop] = v;
        } else {
          delete value[prop];
        }
      }
    })
  };
})();

// -------------------------------

const data = [ { id: 'one', pId: 'foo1', cId: 'bar1' }, { id: 'three', pId: 'foo3', cId: 'bar3' } ];
const toAdd = { id: 'two', pId: 'foo2', cId: 'bar2' };

const exec = (fn) => {
  console.log('---------------');
  console.log(fn.toString());
  console.log(fn());
  console.log(data);
};

You should use Javascript animations for this - it is not possible in pure CSS, because you can't know the height of any element. Follow the instructions it has for you about javascript animation implementation, and copy slideUp and slideDown from jQuery's source.

I would recommend creating a HashMap from set A, and then iterating through set B and checking if any element of B is in A. This would run in O(|A|+|B|) time (as there would be no collisions), whereas retainAll(Collection<?> c) must run in O(|A|*|B|) time.

Do you know sprintf? It's basically the same thing with fprintf. The first argument is the destination (the file in the case of fprintf i.e. stderr), the second argument is the format string, and the rest are the arguments as usual.

I also recommend this printf (and family) reference.

As the OP references Number of commits on branch in git I want to add that the given answers there also work with any other branch, at least since git version 2.17.1 (and seemingly more reliably than the answer by Peter van der Does):

working correctly:

git checkout current-development-branch
git rev-list --no-merges --count master..
62
git checkout -b testbranch_2
git rev-list --no-merges --count current-development-branch..
0

The last command gives zero commits as expected since I just created the branch. The command before gives me the real number of commits on my development-branch minus the merge-commit(s)

not working correctly:

git checkout current-development-branch
git rev-list --no-merges --count HEAD
361
git checkout -b testbranch_1
git rev-list --no-merges --count HEAD
361

In both cases I get the number of all commits in the development branch and master from which the branches (indirectly) descend.

Old post but I made an good solution what is tested on serval places.

https://github.com/CreativForm/Load-jQuery-if-it-is-not-already-loaded

CODE:

(function(url, position, callback){
    // default values
    url = url || 'https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js';
    position = position || 0;

    // Check is jQuery exists
    if (!window.jQuery) {
        // Initialize <head>
        var head = document.getElementsByTagName('head')[0];
        // Create <script> element
        var script = document.createElement("script");
        // Append URL
        script.src = url;
        // Append type
        script.type = 'text/javascript';
        // Append script to <head>
        head.appendChild(script);
        // Move script on proper position
        head.insertBefore(script,head.childNodes[position]);

        script.onload = function(){
            if(typeof callback == 'function') {
                callback(jQuery);
            }
        };
    } else {
        if(typeof callback == 'function') {
            callback(jQuery);
        }
    }
}('https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js', 5, function($){ 
    console.log($);
}));

At GitHub is better explanation but generaly this function you can add anywhere in your HTML code and you will initialize jquery if is not already loaded.

This produces the same results as using __year, __month, and __day and seems to work for me:

YourModel.objects.filter(your_datetime_field__startswith=datetime.date(2009,8,22))

You can use Lodash

const _ = require('lodash');

let firstObject = {'email' : '[email protected]};
let secondObject = { 'name' : { 'first':message.firstName } };
_.merge(firstObject, secondObject)

    self.navigationController?.navigationBar.tintColor = UIColor.black // to change the all text color in navigation bar or navigation 
    self.navigationController?.navigationBar.barTintColor = UIColor.white // change the navigation background color
    self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName:UIColor.black] // To change only navigation bar title text color

Maybe I missed the point but in reply to NAVY guy here is how the browser can tell you the 'requestor's' IP address (albeit maybe only their service provider).

Place a script tag in the page to be rendered by the client that calls (has src pointing to) another server that is not loaded balanced (I realize that this means you need access to a 2nd server but hosting is cheap these days and you can set this up easily and cheaply).

This is the kind of code that needs to be added to client page:

On the other server "someServerIown" you need to have the ASP, ASPX or PHP page that;

----- contains server code like this:

"<% Response.Write("var clientipaddress = '" & Request.ServerVariables("REMOTE_ADDR") & "';") %>" (without the outside dbl quotes :-))

---- and writes this code back to script tag:

   var clientipaddress = '178.32.21.45';

This effectively creates a Javascript variable that you can access with Javascript on the page no less.

Hopefully, you access this var and write the value to a form control ready for sending back.

When the user posts or gets on the next request your Javascript and/or form sends the value of the variable that the "otherServerIown" has filled in for you, back to the server you would like it on.

This is how I get around the dumb load balancer we have that masks the client IP address and makes it appear as that of the Load balancer .... dumb ... dumb dumb dumb!

I haven't given the exact solution because everyone's situation is a little different. The concept is sound, however. Also, note if you are doing this on an HTTPS page your "otherServerIOwn" must also deliver in that secure form otherwise Client is alerted to mixed content. And if you do have https then make sure ALL your certs are valid otherwise client also gets a warning.

Hope it helps someone! Sorry, it took a year to answer/contribute. :-)

If you are using it in a script, use stat.

$ date | tee /tmp/foo
Wed Mar 13 05:36:31 UTC 2019

$ stat -c %s /tmp/foo
29

$ ls -l /tmp/foo
-rw-r--r--  1 bruno  wheel  29 Mar 13 05:36 /tmp/foo

That will give you size in bytes. See man stat for more output format options.

The OSX/BSD equivalent is:

$ date | tee /tmp/foo
Wed Mar 13 00:54:16 EDT 2019

$ stat -f %z /tmp/foo
29

$ ls -l /tmp/foo
-rw-r--r--  1 bruno  wheel  29 Mar 13 00:54 /tmp/foo

To generate a number between 10 to 20 inclusive, you can use java.util.Random

int myNumber = new Random().nextInt(11) + 10

2021 Solution

if your PostgreSQL database is on your system locally.

psql dbname < sqldump.sql username

If its hosted online

psql -h hostname dbname < sqldump.sql username

If you have any doubts or questions, please ask them in the comments.

My solution, if you dont need to have .bat file, is to convert the batch file to .exe file then you will be able to set up run as admin.

The error pretty much explains what the problem is: you are trying to include a file that is not there.

Try to use the full path to the file, using realpath(), and use dirname(__FILE__) to get your current directory:

require_once(realpath(dirname(__FILE__) . '/../includes/dbconn.inc'));

Try this, BigDecimal bdVal = new BigDecimal(str);

If you want Double only then try Double d = Double.valueOf(str); System.out.println(String.format("%.3f", new BigDecimal(d)));

You can use default_scope to implement a default sort order http://api.rubyonrails.org/classes/ActiveRecord/Scoping/Default/ClassMethods.html

Once I encounterred a build which could not be stopped by the "Script Console". Finally I solved the problem with these steps:

ssh onto the jenkins server
cd to .jenkins/jobs/<job-name>/builds/
rm -rf <build-number>
restart jenkins

if (set no count== off)

{ then it will keep data of how many records affected so reduce performance } else { it will not track the record of changes hence improve perfomace } }

I use Visual Studio 2008, and you can customize what you want this shortcut to be.

Click menu Tools -> Options -> Environment -> Keyboard. Then look for Edit.GotoBrace.

This will tell you what key combination is currently assigned for this. I think you can change this if you want, but it's useful if the Ctrl + ] doesn't work.

Taken from @bmpsini and @Jazaret responses, but not extending prototypes: using plain functions (Why is extending native objects a bad practice?):

function isLeapYear(year) { 
    return (((year % 4 === 0) && (year % 100 !== 0)) || (year % 400 === 0)); 
}

function getDaysInMonth(year, month) {
    return [31, (isLeapYear(year) ? 29 : 28), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31][month];
}

function addMonths(date, value) {
    var d = new Date(date),
        n = date.getDate();
    d.setDate(1);
    d.setMonth(d.getMonth() + value);
    d.setDate(Math.min(n, getDaysInMonth(d.getFullYear(), d.getMonth())));
    return d;
}

Use it:

var nextMonth = addMonths(new Date(), 1);

Try

LimitRequestBody 1024000000

I think this is the best and easiest way to do it:

if (!(isset($action) && ($action == "add" || $action == "delete")))

<div id="about">About Snakelane</div>

<input type="image" src="http://www.blakechris.com/snakelane/assets/about.png" onclick="init()" id="btn">
<script>
var about;   
function init() { 
    about = document.getElementById("about");
    about.style.color = 'blue';
}

1. Right click on the project file -> Add -> New Item -> Application Configuration File. This will add an app.config (or web.config) file to your project.

2. The ConfigurationManager class would be a good start. You can use it to read different configuration values from the configuration file.

I suggest you start reading the MSDN document about Configuration Files.

An HTTP response code of 0 indicates that the AJAX request was cancelled.

This can happen either from a timeout, XHR abortion or a firewall stomping on the request. A timeout is common, it means the request failed to execute within a specified time. An XHR Abortion is very simple to do... you can actually call .abort() on an XMLHttpRequest object to cancel the AJAX call. (This is good practice for a single page application if you don't want AJAX calls returning and attempting to reference objects that have been destroyed.) As mentioned in the marked answer, a firewall would also be capable of cancelling the request and trigger this 0 response.

XHR Abort: Abort Ajax requests using jQuery

var xhr = $.ajax({
    type: "POST",
    url: "some.php",
    data: "name=John&location=Boston",
    success: function(msg){
       alert( "Data Saved: " + msg );
    }
});

//kill the request
xhr.abort()

It's worth noting that running the .abort() method on an XHR object will also fire the error callback. If you're doing any kind of error handling that parses these objects, you'll quickly notice that an aborted XHR and a timeout XHR are identical, but with jQuery the textStatus that is passed to the error callback will be "abort" when aborted and "timeout" with a timeout occurs. If you're using Zepto (very very similar to jQuery) the errorType will be "error" when aborted and "timeout" when a timeout occurs.

jQuery: error(jqXHR, textStatus, errorThrown);
Zepto:  error(xhr, errorType, error);

insert into bookmarks (users_id, lessoninfo_id)

select 1, 167
EXCEPT
select user_id, lessoninfo_id
from bookmarks
where user_id=1
and lessoninfo_id=167;

This is the fastest way.

For some other SQL engines, you can use a Dummy table containing 1 record. e.g:

select 1, 167 from ONE_RECORD_DUMMY_TABLE

What do you want to fade? The background or color attribute?

Currently you're changing the background color, but telling it to transition the color property. You can use all to transition all properties.

.clicker { 
    -moz-transition: all .2s ease-in;
    -o-transition: all .2s ease-in;
    -webkit-transition: all .2s ease-in;
    transition: all .2s ease-in;
    background: #f5f5f5; 
    padding: 20px;
}

.clicker:hover { 
    background: #eee;
}

Otherwise just use transition: background .2s ease-in.

Use LINQ - The beauty of C#

DataTable newDataTable = baseTable.AsEnumerable()
                   .OrderBy(r=> r.Field<int>("ColumnName"))
                   .CopyToDataTable();

To my understanding, when you need to train a NN, you need a large dataset involves many data items. when NN is being trained, data items go in to NN one by one, that is called an iteration; When the whole dataset goes through, it is called an epoch.

That's Media Queries. It allows you to apply part of CSS rules only to the specific devices on specific configuration.

Well by doing the above you open yourself to run time errors, unless you are happy to accept that your arraylists can contains both strings and integers and elephants.

Eclipse returns an error because it does not want you to be unaware of the fact that by specifying no type for the generic parameter you are opening yourself up for run time errors. At least with the other two examples you know that you can have objects in your Arraylist and since Inetegers and Strings are both objects Eclipse doesn't warn you.

Either code 2 or 3 are ok. But if you know you will have either only ints or only strings in your arraylist then I would do

ArrayList<Integer> arr = new ArrayList<Integer>();

or

ArrayList<String> arr = new ArrayList<String>();

respectively.

use this one

//for getting length of object
 int length = jsonObject.length();

or

//for getting length of array
 int length = jsonArray.length();

Here is the one of the better solutions.

DECLARE @i int
            DECLARE @curren_val int
            DECLARE @numrows int
            create table #Practitioner (idx int IDENTITY(1,1), PractitionerId int)
            INSERT INTO #Practitioner (PractitionerId) values (10),(20),(30)
            SET @i = 1
            SET @numrows = (SELECT COUNT(*) FROM #Practitioner)
            IF @numrows > 0
            WHILE (@i <= (SELECT MAX(idx) FROM #Practitioner))
            BEGIN

                SET @curren_val = (SELECT PractitionerId FROM #Practitioner WHERE idx = @i)

                --Do something with Id here
                PRINT @curren_val
                SET @i = @i + 1
            END

Here i've add some values in the table beacuse, initially it is empty.

We can access or we can do anything in the body of the loop and we can access the idx by defining it inside the table definition.

              BEGIN
                SET @curren_val = (SELECT PractitionerId FROM #Practitioner WHERE idx = @i)

                --Do something with Id here

                PRINT @curren_val
                SET @i = @i + 1
            END

Please try the following code snippet,

IIF(Round(Avg(Fields!Vision_Score.Value)) = Avg(Fields!Vision_Score.Value), 
Format(Avg(Fields!Vision_Score.Value)), 
FORMAT(Avg(Fields!Vision_Score.Value),"##.##"))

hope it will help, Thank-you.

You can load an XML document into an XMLType, then query it, e.g.:

DECLARE
  x XMLType := XMLType(
    '<?xml version="1.0" ?> 
<person>
   <row>
       <name>Tom</name>
       <Address>
           <State>California</State>
           <City>Los angeles</City>
       </Address>
   </row>
   <row>
       <name>Jim</name>
       <Address>
           <State>California</State>
           <City>Los angeles</City>
       </Address>
   </row>
</person>');
BEGIN
  FOR r IN (
    SELECT ExtractValue(Value(p),'/row/name/text()') as name
          ,ExtractValue(Value(p),'/row/Address/State/text()') as state
          ,ExtractValue(Value(p),'/row/Address/City/text()') as city
    FROM   TABLE(XMLSequence(Extract(x,'/person/row'))) p
    ) LOOP
    -- do whatever you want with r.name, r.state, r.city
  END LOOP;
END;

Apart from the settings explained in the answer by @DarkNeuron:

"files.encoding": "any encoding"

you can also specify settings for a specific language like so:

"[language id]": {
  "files.encoding": "any encoding"
}

For example, I use this when I need to edit PowerShell files previously created with ISE (which are created in ANSI format):

"[powershell]": {
    "files.encoding": "windows1252"
}

You can get a list of identifiers of well-known languages here.

You can create space between table rows by adding an empty row of cells like this...

<tr><td></td><td></td></tr>

CSS can then be used to target the empty cells like this…

table :empty{border:none; height:10px;}

NB: This technique is only good if none of your normal cells will be empty/vacant.

Even a non-breaking space will do to avoid a cell from being targetted by the CSS rule above.

Needless to mention that you can adjust the space's height to whatever you like with the height property included.

you can use

 - (void)highlightLetter:(UITapGestureRecognizer*)sender {
     UIView *view = sender.view; 
     NSLog(@"%d", view.tag); 
}

view will be the Object in which the tap gesture was recognised

This will work

@Cacheable(value="bookCache", key="#checkwarehouse.toString().append(#isbn.toString())")

Another solution, declare your controller as UITextFieldDelegate, implement this call-back:

@IBOutlet weak var myTextField: UITextField!

override func viewDidLoad() {
    super.viewDidLoad()

    myTextField.delegate = self
}

func textFieldShouldBeginEditing(textField: UITextField) -> Bool {
    if textField == myTextField {
        return false; //do not show keyboard nor cursor
    }
    return true
}

Although Bootstrap CDN restored glyphicons to bootstrap.min.css, Bootstrap CDN's Bootswatch css files doesn't include glyphicons.

For example Amelia theme: http://bootswatch.com/amelia/

Default Amelia has glyphicons in this file: http://bootswatch.com/amelia/bootstrap.min.css

But Bootstrap CDN's css file doesn't include glyphicons: http://netdna.bootstrapcdn.com/bootswatch/3.0.0/amelia/bootstrap.min.css

So as @edsioufi mentioned, you should include you should include glphicons css, if you use Bootswatch files from the bootstrap CDN. File: http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap-glyphicons.css

HTML:

<tr>
    <th>Language</th>
    <th>Skill Level</th>
    <th>&nbsp;</th>
</tr>

CSS:

tr, th {
    padding: 10px;
    text-align: center;
}

• For Jetbrains IDE Users who migrated to VSCode , no problem.

• Install:
  1) JetBrains IDE Keymap: Extension
  2) vscode-intellij-idea-keybindings Extension (Preferred)

• Use this Intellij Darcula Theme: Extension

• The keymap has covered most of keyboard shortcuts of VS Code, and makes VS Code more 'JetBrains IDE like'.

• Above extensions imports keybindings from JetBrains to VS Code. After installing the extension and restarting VS Code you can use VS Code just like IntelliJ IDEA, Webstorm, PyCharm, etc.

This is a working example of making ZIPs in PHP:

$zip = new ZipArchive();
$zip_name = time().".zip"; // Zip name
$zip->open($zip_name,  ZipArchive::CREATE);
foreach ($files as $file) {
  echo $path = "uploadpdf/".$file;
  if(file_exists($path)){
  $zip->addFromString(basename($path),  file_get_contents($path));  
  }
  else{
   echo"file does not exist";
  }
}
$zip->close();

Just a minor addition: if you add the -c flag to ps, you don't need to remove the line containing the grep process with grep -v afterwards. I.e.

ps acux | grep cron

is all the typing you'll need on a bsd-ish system (this includes MacOSX) You can leave the -u away if you need less information.

On a system where the genetics of the native ps command point back to SysV, you'd use

ps -e |grep cron

or

ps -el |grep cron 

for a listing containing more than just pid and process name. Of course you could select the specific fields to print out using the -o <field,field,...> option.

If repeating the same code is the issue, write an extension method on the String class that encapsulates the splitting logic.

Most likely your query failed, and the query call returned a boolean FALSE (or an error object of some sort), which you then try to use as if was a resultset object, causing the error. Try something like var_dump($result) to see what you really got.

Check for errors after EVERY database query call. Even if the query itself is syntactically valid, there's far too many reasons for it to fail anyways - checking for errors every time will save you a lot of grief at some point.

This is how I did it.

from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--disable-extensions')

chrome = webdriver.Chrome(chrome_options=chrome_options)

The format you use for the date doesn't match to Oracle's default date format.

A default installation of Oracle Database sets the DEFAULT DATE FORMAT to dd-MMM-yyyy.

Either use the function TO_DATE(dateStr, formatStr) or simply use dd-MMM-yyyy date format model.

The following should work:

ABC: *\([a-zA-Z]+\) *(.+)

Explanation:

ABC:            # match literal characters 'ABC:'
 *              # zero or more spaces
\([a-zA-Z]+\)   # one or more letters inside of parentheses
 *              # zero or more spaces
(.+)            # capture one or more of any character (except newlines)

To get your desired grouping based on the comments below, you can use the following:

(ABC:) *(\([a-zA-Z]+\).+)

Adding another way of doing it exactly what the OP asked for, without using latest inbuilt methods:

public static String getDay(String inputDate) {
    String dayOfWeek = null;
    String[] days = new String[]{"Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"};

    try {
        SimpleDateFormat format1 = new SimpleDateFormat("dd/MM/yyyy");
        Date dt1 = format1.parse(inputDate);
        dayOfWeek = days[dt1.getDay() - 1];
    } catch(Exception e) {
        System.out.println(e);
    }

    return dayOfWeek;
}

str1.toLowerCase().contains(str2.toLowerCase())

Updates an old config with new/changed/removed options.

Follow the following steps:

1. Open the XAMPP control panel and click on the shell and open the shell.
2. In the shell run the following : mysql -h localhost -u root -p and press enter. It will as for a password, by default the password is blank so just press enter
3. Then just run the following query SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpassword'); and press enter and your password is updated for root user on localhost

Why reinvent the wheel? Use Commons Collections:

CollectionUtils.intersection(java.util.Collection a, java.util.Collection b)

@Column is not the appropriate annotation. You don't want to store a whole User or Question in a column. You want to create an association between the entities. Start by renaming Questions to Question, since an instance represents a single question, and not several ones. Then create the association:

@Entity
@Table(name = "UserAnswer")
public class UserAnswer {

    // this entity needs an ID:
    @Id
    @Column(name="useranswer_id")
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @ManyToOne
    @JoinColumn(name = "user_id")
    private User user;

    @ManyToOne
    @JoinColumn(name = "question_id")
    private Question question;

    @Column(name = "response")
    private String response;

    //getter and setter 
}

The Hibernate documentation explains that. Read it. And also read the javadoc of the annotations.

$.fn.scrollEnd = function(callback, timeout) {          
  $(this).scroll(function(){
    var $this = $(this);
    if ($this.data('scrollTimeout')) {
      clearTimeout($this.data('scrollTimeout'));
    }
    $this.data('scrollTimeout', setTimeout(callback,timeout));
  });
};

$(window).scroll(function(){
    $('.main').fadeOut();
});

$(window).scrollEnd(function(){
    $('.main').fadeIn();
}, 700);

That should do the Trick!

You can test it out in this jsbin: http://jsbin.com/uxecel/4/edit

When you do new Promise((resolve)... the type inferred was Promise<{}> because you should have used new Promise<number>((resolve).

It is interesting that this issue was only highlighted when the async keyword was added. I would recommend reporting this issue to the TS team on GitHub.

There are many ways you can get around this issue. All the following functions have the same behavior:

const whatever1 = () => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever2 = async () => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever3 = async () => {
    return await new Promise<number>((resolve) => {
        resolve(4);
    });
};

const whatever4 = async () => {
    return Promise.resolve(4);
};

const whatever5 = async () => {
    return await Promise.resolve(4);
};

const whatever6 = async () => Promise.resolve(4);

const whatever7 = async () => await Promise.resolve(4);

In your IDE you will be able to see that the inferred type for all these functions is () => Promise<number>.

There is one more Java mapping engine/framework Nomin: http://nomin.sourceforge.net.

find . -type f -print0 | xargs -0 <sed/perl/ruby cmd> will process multiple space contained file names at once loading one interpreter per batch. Much faster.

This is a subjective opinion, but I think a text editor shouldn't do everything and the kitchen sink. I prefer lightweight flexible and powerful (in their specialized fields) editors. Although being mostly a Windows user, I like the Unix philosophy of having lot of specialized tools that you can pipe together (like the UnxUtils) rather than a monster doing everything, but not necessarily as you would like it!

Find in files is on the border of these extra features, but useful when you can double-click on a found line to open the file at the right line. Note that initially, in SciTE it was just a Tools call to grep or equivalent!
FTP is very close to off topic, although it can be seen as an extended open/save dialog.
Replace in files is too much IMO: it is dangerous (you can mess lot of files at once) if you have no preview, etc. I would rather use a specialized tool I chose, perhaps among those in Multi line search and replace tool.

To answer the question, looking at N++, I see a Run menu where you can launch any tool, with assignment of a name and shortcut key. I see also Plugins > NppExec, which seems able to launch stuff like sed (not tried it).

or even a very classic old fashion method

IEnumerable<string> collection = new List<string>() { "a", "b", "c" };

for(int i = 0; i < collection.Count(); i++) 
{
    string str1 = collection.ElementAt(i);
    // do your stuff   
}

maybe you would like this method also :-)
