Synchronized Vs Atomic Vs Volatile:

• Volatile and Atomic is apply only on variable , While Synchronized apply on method.
• Volatile ensure about visibility not atomicity/consistency of object , While other both ensure about visibility and atomicity.
• Volatile variable store in RAM and it’s faster in access but we can’t achive Thread safety or synchronization whitout synchronized keyword.
• Synchronized implemented as synchronized block or synchronized method while both not. We can thread safe multiple line of code with help of synchronized keyword while with both we can’t achieve the same.
• Synchronized can lock the same class object or different class object while both can’t.

Please correct me if anything i missed.

Worst (won't actually work)

Change the access modifier of counter to public volatile

As other people have mentioned, this on its own isn't actually safe at all. The point of volatile is that multiple threads running on multiple CPUs can and will cache data and re-order instructions.

If it is not volatile, and CPU A increments a value, then CPU B may not actually see that incremented value until some time later, which may cause problems.

If it is volatile, this just ensures the two CPUs see the same data at the same time. It doesn't stop them at all from interleaving their reads and write operations which is the problem you are trying to avoid.

Second Best:

lock(this.locker) this.counter++;

This is safe to do (provided you remember to lock everywhere else that you access this.counter). It prevents any other threads from executing any other code which is guarded by locker. Using locks also, prevents the multi-CPU reordering problems as above, which is great.

The problem is, locking is slow, and if you re-use the locker in some other place which is not really related then you can end up blocking your other threads for no reason.

Best

Interlocked.Increment(ref this.counter);

This is safe, as it effectively does the read, increment, and write in 'one hit' which can't be interrupted. Because of this, it won't affect any other code, and you don't need to remember to lock elsewhere either. It's also very fast (as MSDN says, on modern CPUs, this is often literally a single CPU instruction).

I'm not entirely sure however if it gets around other CPUs reordering things, or if you also need to combine volatile with the increment.

InterlockedNotes:

1. INTERLOCKED METHODS ARE CONCURRENTLY SAFE ON ANY NUMBER OF COREs OR CPUs.
2. Interlocked methods apply a full fence around instructions they execute, so reordering does not happen.
3. Interlocked methods do not need or even do not support access to a volatile field, as volatile is placed a half fence around operations on given field and interlocked is using the full fence.

Footnote: What volatile is actually good for.

As volatile doesn't prevent these kinds of multithreading issues, what's it for? A good example is saying you have two threads, one which always writes to a variable (say queueLength), and one which always reads from that same variable.

If queueLength is not volatile, thread A may write five times, but thread B may see those writes as being delayed (or even potentially in the wrong order).

A solution would be to lock, but you could also use volatile in this situation. This would ensure that thread B will always see the most up-to-date thing that thread A has written. Note however that this logic only works if you have writers who never read, and readers who never write, and if the thing you're writing is an atomic value. As soon as you do a single read-modify-write, you need to go to Interlocked operations or use a Lock.

Difference Between Static and Volatile :

Static Variable: If two Threads(suppose t1 and t2) are accessing the same object and updating a variable which is declared as static then it means t1 and t2 can make their own local copy of the same object(including static variables) in their respective cache, so update made by t1 to the static variable in its local cache wont reflect in the static variable for t2 cache .

Static variables are used in the context of Object where update made by one object would reflect in all the other objects of the same class but not in the context of Thread where update of one thread to the static variable will reflect the changes immediately to all the threads (in their local cache).

Volatile variable: If two Threads(suppose t1 and t2) are accessing the same object and updating a variable which is declared as volatile then it means t1 and t2 can make their own local cache of the Object except the variable which is declared as a volatile . So the volatile variable will have only one main copy which will be updated by different threads and update made by one thread to the volatile variable will immediately reflect to the other Thread.

The Wiki say everything about volatile:

• volatile (computer programming)

And the Linux kernel's doc also make a excellent notation about volatile:

• Why the "volatile" type class should not be used

A variable declared with volatile keyword, has two main qualities which make it special.

1. If we have a volatile variable, it cannot be cached into the computer's(microprocessor) cache memory by any thread. Access always happened from main memory.

2. If there is a write operation going on a volatile variable, and suddenly a read operation is requested, it is guaranteed that the write operation will be finished prior to the read operation.

Two above qualities deduce that

• All the threads reading a volatile variable will definitely read the latest value. Because no cached value can pollute it. And also the read request will be granted only after the completion of the current write operation.

And on the other hand,

• If we further investigate the #2 that I have mentioned, we can see that volatile keyword is an ideal way to maintain a shared variable which has 'n' number of reader threads and only one writer thread to access it. Once we add the volatile keyword, it is done. No any other overhead about thread safety.

Conversly,

We can't make use of volatile keyword solely, to satisfy a shared variable which has more than one writer thread accessing it.

It's important to understand that there are two aspects to thread safety.

1. execution control, and
2. memory visibility

The first has to do with controlling when code executes (including the order in which instructions are executed) and whether it can execute concurrently, and the second to do with when the effects in memory of what has been done are visible to other threads. Because each CPU has several levels of cache between it and main memory, threads running on different CPUs or cores can see "memory" differently at any given moment in time because threads are permitted to obtain and work on private copies of main memory.

Using synchronized prevents any other thread from obtaining the monitor (or lock) for the same object, thereby preventing all code blocks protected by synchronization on the same object from executing concurrently. Synchronization also creates a "happens-before" memory barrier, causing a memory visibility constraint such that anything done up to the point some thread releases a lock appears to another thread subsequently acquiring the same lock to have happened before it acquired the lock. In practical terms, on current hardware, this typically causes flushing of the CPU caches when a monitor is acquired and writes to main memory when it is released, both of which are (relatively) expensive.

Using volatile, on the other hand, forces all accesses (read or write) to the volatile variable to occur to main memory, effectively keeping the volatile variable out of CPU caches. This can be useful for some actions where it is simply required that visibility of the variable be correct and order of accesses is not important. Using volatile also changes treatment of long and double to require accesses to them to be atomic; on some (older) hardware this might require locks, though not on modern 64 bit hardware. Under the new (JSR-133) memory model for Java 5+, the semantics of volatile have been strengthened to be almost as strong as synchronized with respect to memory visibility and instruction ordering (see http://www.cs.umd.edu/users/pugh/java/memoryModel/jsr-133-faq.html#volatile). For the purposes of visibility, each access to a volatile field acts like half a synchronization.

Under the new memory model, it is still true that volatile variables cannot be reordered with each other. The difference is that it is now no longer so easy to reorder normal field accesses around them. Writing to a volatile field has the same memory effect as a monitor release, and reading from a volatile field has the same memory effect as a monitor acquire. In effect, because the new memory model places stricter constraints on reordering of volatile field accesses with other field accesses, volatile or not, anything that was visible to thread A when it writes to volatile field f becomes visible to thread B when it reads f.

-- JSR 133 (Java Memory Model) FAQ

So, now both forms of memory barrier (under the current JMM) cause an instruction re-ordering barrier which prevents the compiler or run-time from re-ordering instructions across the barrier. In the old JMM, volatile did not prevent re-ordering. This can be important, because apart from memory barriers the only limitation imposed is that, for any particular thread, the net effect of the code is the same as it would be if the instructions were executed in precisely the order in which they appear in the source.

One use of volatile is for a shared but immutable object is recreated on the fly, with many other threads taking a reference to the object at a particular point in their execution cycle. One needs the other threads to begin using the recreated object once it is published, but does not need the additional overhead of full synchronization and it's attendant contention and cache flushing.

// Declaration
public class SharedLocation {
    static public SomeObject someObject=new SomeObject(); // default object
    }

// Publishing code
// Note: do not simply use SharedLocation.someObject.xxx(), since although
//       someObject will be internally consistent for xxx(), a subsequent 
//       call to yyy() might be inconsistent with xxx() if the object was 
//       replaced in between calls.
SharedLocation.someObject=new SomeObject(...); // new object is published

// Using code
private String getError() {
    SomeObject myCopy=SharedLocation.someObject; // gets current copy
    ...
    int cod=myCopy.getErrorCode();
    String txt=myCopy.getErrorText();
    return (cod+" - "+txt);
    }
// And so on, with myCopy always in a consistent state within and across calls
// Eventually we will return to the code that gets the current SomeObject.

Speaking to your read-update-write question, specifically. Consider the following unsafe code:

public void updateCounter() {
    if(counter==1000) { counter=0; }
    else              { counter++; }
    }

Now, with the updateCounter() method unsynchronized, two threads may enter it at the same time. Among the many permutations of what could happen, one is that thread-1 does the test for counter==1000 and finds it true and is then suspended. Then thread-2 does the same test and also sees it true and is suspended. Then thread-1 resumes and sets counter to 0. Then thread-2 resumes and again sets counter to 0 because it missed the update from thread-1. This can also happen even if thread switching does not occur as I have described, but simply because two different cached copies of counter were present in two different CPU cores and the threads each ran on a separate core. For that matter, one thread could have counter at one value and the other could have counter at some entirely different value just because of caching.

What's important in this example is that the variable counter was read from main memory into cache, updated in cache and only written back to main memory at some indeterminate point later when a memory barrier occurred or when the cache memory was needed for something else. Making the counter volatile is insufficient for thread-safety of this code, because the test for the maximum and the assignments are discrete operations, including the increment which is a set of non-atomic read+increment+write machine instructions, something like:

MOV EAX,counter
INC EAX
MOV counter,EAX

Volatile variables are useful only when all operations performed on them are "atomic", such as my example where a reference to a fully formed object is only read or written (and, indeed, typically it's only written from a single point). Another example would be a volatile array reference backing a copy-on-write list, provided the array was only read by first taking a local copy of the reference to it.

The effect of the volatile keyword is approximately that each individual read or write operation on that variable is atomic.

Notably, however, an operation that requires more than one read/write -- such as i++, which is equivalent to i = i + 1, which does one read and one write -- is not atomic, since another thread may write to i between the read and the write.

The Atomic classes, like AtomicInteger and AtomicReference, provide a wider variety of operations atomically, specifically including increment for AtomicInteger.

Boolean primitive type is atomic for write and read operations, volatile guarantees the happens-before principle. So if you need a simple get() and set() then you don't need the AtomicBoolean.

On the other hand if you need to implement some check before setting the value of a variable, e.g. "if true then set to false", then you need to do this operation atomically as well, in this case use compareAndSet and other methods provided by AtomicBoolean, since if you try to implement this logic with volatile boolean you'll need some synchronization to be sure that the value has not changed between get and set.

Consider this code,

int some_int = 100;

while(some_int == 100)
{
   //your code
}

When this program gets compiled, the compiler may optimize this code, if it finds that the program never ever makes any attempt to change the value of some_int, so it may be tempted to optimize the while loop by changing it from while(some_int == 100) to something which is equivalent to while(true) so that the execution could be fast (since the condition in while loop appears to be true always). (if the compiler doesn't optimize it, then it has to fetch the value of some_int and compare it with 100, in each iteration which obviously is a little bit slow.)

However, sometimes, optimization (of some parts of your program) may be undesirable, because it may be that someone else is changing the value of some_int from outside the program which compiler is not aware of, since it can't see it; but it's how you've designed it. In that case, compiler's optimization would not produce the desired result!

So, to ensure the desired result, you need to somehow stop the compiler from optimizing the while loop. That is where the volatile keyword plays its role. All you need to do is this,

volatile int some_int = 100; //note the 'volatile' qualifier now!

In other words, I would explain this as follows:

volatile tells the compiler that,

"Hey compiler, I'm volatile and, you know, I can be changed by some XYZ that you're not even aware of. That XYZ could be anything. Maybe some alien outside this planet called program. Maybe some lightning, some form of interrupt, volcanoes, etc can mutate me. Maybe. You never know who is going to change me! So O you ignorant, stop playing an all-knowing god, and don't dare touch the code where I'm present. Okay?"

Well, that is how volatile prevents the compiler from optimizing code. Now search the web to see some sample examples.

Quoting from the C++ Standard ($7.1.5.1/8)

[..] volatile is a hint to the implementation to avoid aggressive optimization involving the object because the value of the object might be changed by means undetectable by an implementation.[...]

One more solution able to control the how many decimal digits to print out based on needs (if you don't want to print redundant zero(s))

For example, if you have a vector as elements and would like to get sum of it

elements <- c(-1e-05, -2e-04, -3e-03, -4e-02, -5e-01, -6e+00, -7e+01, -8e+02)
sum(elements)
## -876.5432

Apparently, the last digital as 1 been truncated, the ideal result should be -876.54321, but if set as fixed printing decimal option, e.g sprintf("%.10f", sum(elements)), redundant zero(s) generate as -876.5432100000

Following the tutorial here: printing decimal numbers, if able to identify how many decimal digits in the certain numeric number, like here in -876.54321, there are 5 decimal digits need to print, then we can set up a parameter for format function as below:

decimal_length <- 5
formatC(sum(elements), format = "f", digits = decimal_length)
## -876.54321

We can change the decimal_length based on each time query, so it can satisfy different decimal printing requirement.

But I need the match result to be ... not in a match group...

For what you are trying to do, this should work. \K resets the starting point of the match.

I used axios-mock-adapter. In this case the service is described in ./chatbot. In the mock adapter you specify what to return when the API endpoint is consumed.

import axios from 'axios';
import MockAdapter from 'axios-mock-adapter';
import chatbot from './chatbot';

describe('Chatbot', () => {
    it('returns data when sendMessage is called', done => {
        var mock = new MockAdapter(axios);
        const data = { response: true };
        mock.onGet('https://us-central1-hutoma-backend.cloudfunctions.net/chat').reply(200, data);

        chatbot.sendMessage(0, 'any').then(response => {
            expect(response).toEqual(data);
            done();
        });
    });
});

1. Open a command prompt as an Administrator.

2. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.

3. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.

4. Enter slmgr /rearm and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.

This should put the system back to a pre-key state.

Hope this helps you out!

this is very easy way to do this without any Library: if the OS version is not supported - under kitkat - so nothing happend. i do this steps:

1. in my xml i added to the top this View:

<View
        android:id="@+id/statusBarBackground"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

then i made this method:

 public void setStatusBarColor(View statusBar,int color){
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
           Window w = getWindow();
           w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
           //status bar height
           int actionBarHeight = getActionBarHeight();
           int statusBarHeight = getStatusBarHeight();
           //action bar height
           statusBar.getLayoutParams().height = actionBarHeight + statusBarHeight;
           statusBar.setBackgroundColor(color);
     }
}

also you need those both methods to get action Bar & status bar height:

public int getActionBarHeight() {
    int actionBarHeight = 0;
    TypedValue tv = new TypedValue();
    if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true))
    {
       actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,getResources().getDisplayMetrics());
    }
    return actionBarHeight;
}

public int getStatusBarHeight() {
    int result = 0;
    int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
    if (resourceId > 0) {
        result = getResources().getDimensionPixelSize(resourceId);
    }
    return result;
}

then the only thing you need is this line to set status bar color:

setStatusBarColor(findViewById(R.id.statusBarBackground),getResources().getColor(android.R.color.white));

To add up to Louis answer:

Alternatively you can use the attribute ToolVersion="12.0" if you are using Visual Studio 2013 instead of using the ToolPath Attribute. Details visit http://msdn.microsoft.com/en-us/library/dd647548.aspx

So you are not forced to use absolute path.

System.currentTimeMillis() does give you the number of milliseconds since January 1, 1970 00:00:00 UTC. The reason you see local times might be because you convert a Date instance to a string before using it. You can use DateFormats to convert Dates to Strings in any timezone:

DateFormat df = DateFormat.getTimeInstance();
df.setTimeZone(TimeZone.getTimeZone("gmt"));
String gmtTime = df.format(new Date());

Also see this related question.

Since most of the other replies often get the formatting wrong (due to the piping), the safest thing to do is as follows:

add-content $YourMasterFile -value (get-content $SomeAdditionalFile)

I know you wanted to avoid reading the content of $SomeAdditionalFile into a variable, but in order to save for example your newline formatting i do not think there is proper way to do it without.

A workaround would be to loop through your $SomeAdditionalFile line by line and piping that into your $YourMasterFile. However this is overly resource intensive.

I think with

System.getProperty("os.name"); 

Checking the operating system on can manage the shell/bash scrips if such are supported. if there is need to make the code portable.

My take is that Optional should be a Monad and these are not conceivable in Java.

In functional programming you deal with pure and higher order functions that take and compose their arguments only based on their "business domain type". Composing functions that feed on, or whose computation should be reported to, the real-world (so called side effects) requires the application of functions that take care of automatically unpacking the values out of the monads representing the outside world (State, Configuration, Futures, Maybe, Either, Writer, etc...); this is called lifting. You can think of it as a kind of separation of concerns.

Mixing these two levels of abstraction doesn't facilitate legibility so you're better off just avoiding it.

I get this error all the time and consider it normal.

It happens when one side tries to read when the other side has already hung up. Thus depending on the protocol this may or may not designate a problem. If my client code specifically indicates to the server that it is going to hang up, then both client and server can hang up at the same time and this message would not happen.

The way I implement my code is for the client to just hang up without saying goodbye. The server can then catch the error and ignore it. In the context of HTTP, I believe one level of the protocol allows more then one request per connection while the other doesn't.

Thus you can see how potentially one side could keep hanging up on the other. I doubt the error you are receiving is of any piratical concern and you could simply catch it to keep it from filling up your log files.

• If there is any default export in the file, there isn't any need to use the curly braces in the import statement.

You are right about AccelerateInterpolator; you should use LinearInterpolator instead.

You can use the built-in android.R.anim.linear_interpolator from your animation XML file with android:interpolator="@android:anim/linear_interpolator".

Or you can create your own XML interpolation file in your project, e.g. name it res/anim/linear_interpolator.xml:

<?xml version="1.0" encoding="utf-8"?>
<linearInterpolator xmlns:android="http://schemas.android.com/apk/res/android" />

And add to your animation XML:

android:interpolator="@anim/linear_interpolator"

Special Note: If your rotate animation is inside a set, setting the interpolator does not seem to work. Making the rotate the top element fixes it. (this will save your time.)

This would obviously be different, if you installed Python in a different location.

IANAL but as I see it....

While you can combine GPL and MIT code, the GPL is tainting. Which means the package as a whole gets the limitations of the GPL. As that is more restrictive you can no longer use it in commercial (or rather closed source) software. Which also means if you have a MIT/BSD/ASL project you will not want to add dependencies to GPL code.

Adding a GPL dependency does not change the license of your code but it will limit what people can do with the artifact of your project. This is also why the ASF does not allow dependencies to GPL code for their projects.

@Sydney Try putting wp_reset_query() before you call the loop. This will display the content of your page.

<?php
    wp_reset_query(); // necessary to reset query
    while ( have_posts() ) : the_post();
        the_content();
    endwhile; // End of the loop.
?>

EDIT: Try this if you have some other loops that you previously ran. Place wp_reset_query(); where you find it most suitable, but before you call this loop.

You can automatically do it in Notepad++ (add text at the beginning and/or end of each line) by using one regular expression in Replace (Ctrl+H):

Explanation: Expression $1 in Replace with input denotes all the characters that include the round brackets (.*) in Find what regular expressin.

Tested, it works.

Hope that helps.

Instead of creating a new route for that, you could just redirect to your controller/action and pass the information via querystring. For instance:

protected void Application_Error(object sender, EventArgs e) {
  Exception exception = Server.GetLastError();
  Response.Clear();

  HttpException httpException = exception as HttpException;

  if (httpException != null) {
    string action;

    switch (httpException.GetHttpCode()) {
      case 404:
        // page not found
        action = "HttpError404";
        break;
      case 500:
        // server error
        action = "HttpError500";
        break;
      default:
        action = "General";
        break;
      }

      // clear error on server
      Server.ClearError();

      Response.Redirect(String.Format("~/Error/{0}/?message={1}", action, exception.Message));
    }

Then your controller will receive whatever you want:

// GET: /Error/HttpError404
public ActionResult HttpError404(string message) {
   return View("SomeView", message);
}

There are some tradeoffs with your approach. Be very very careful with looping in this kind of error handling. Other thing is that since you are going through the asp.net pipeline to handle a 404, you will create a session object for all those hits. This can be an issue (performance) for heavily used systems.

I think a better question is, why in a case where you're evaluating a boolean set of return values, would you NOT use true/false? I mean, you could probably have true/null, true/-1, other misc. Javascript "falsy" values to substitute, but why would you do that?

A slightly modified version of Brian's answer allows optional management of read start, This seems to be the easiest method. probably not the most efficient, but easy to understand and use.

Public Function ReadAll(ByVal memStream As MemoryStream, Optional ByVal startPos As Integer = 0) As String
    ' reset the stream or we'll get an empty string returned
    ' remember the position so we can restore it later
    Dim Pos = memStream.Position
    memStream.Position = startPos

    Dim reader As New StreamReader(memStream)
    Dim str = reader.ReadToEnd()

    ' reset the position so that subsequent writes are correct
    memStream.Position = Pos

    Return str
End Function

I guess the simplest way is by DI. An example of reaching into Controller.

// StartUp.cs
public void ConfigureServices(IServiceCollection services)
{
    ...
    // for get appsettings from anywhere
    services.AddSingleton(Configuration);
}

public class ContactUsController : Controller
{
    readonly IConfiguration _configuration;

    public ContactUsController(
        IConfiguration configuration)
    {
        _configuration = configuration;

        // sample:
        var apiKey = _configuration.GetValue<string>("SendGrid:CAAO");
        ...
    }
}

My project had nothing to do with war, but the same error. I had to remove project from eclipse, delete all eclipse files from the project folder and reimport maven project.

Check out Google Collections' Multimap, e.g. page 28 of this presentation.

If you can't use that library for some reason, consider using ConcurrentHashMap instead of SynchronizedHashMap; it has a nifty putIfAbsent(K,V) method with which you can atomically add the element list if it's not already there. Also, consider using CopyOnWriteArrayList for the map values if your usage patterns warrant doing so.

You could do the opposite of what you proposed.

location (/test)/ {
   set $folder $1;
}

location (/test_/something {
   set $folder $1;
}

There is no newline, just the div is a block element.

You can make the div inline by adding display: inline, which may be what you want.

I had the same problem when I was debugging my app. I've rewrote the hash that you have crossed out in the attached image (the one that Facebook says is invalid) and added it in the Facebook's developers console to key hashes. Just be careful of typos.

This solution is more like an easy workaround than a proper solution.

Difficult task. I would normally suggest to grab a debugger/memory profiler like Valgrind and run the programs one after one in it. Soon or later you will find the program that leaks and can tell it the devloper or fix it yourself.

Since Spring 3.0 you also can throw an Exception declared with @ResponseStatus annotation:

@ResponseStatus(value = HttpStatus.NOT_FOUND)
public class ResourceNotFoundException extends RuntimeException {
    ...
}

@Controller
public class SomeController {
    @RequestMapping.....
    public void handleCall() {
        if (isFound()) {
            // whatever
        }
        else {
            throw new ResourceNotFoundException(); 
        }
    }
}

This W3C document explains the use of HTTP GET and POST.

I think it is an authoritative source.

The summary is (section 1.3 of the document):

• Use GET if the interaction is more like a question (i.e., it is a safe operation such as a query, read operation, or lookup).
• Use POST if:
  • The interaction is more like an order, or
  • The interaction changes the state of the resource in a way that the user would perceive (e.g., a subscription to a service), or
  • The user be held accountable for the results of the interaction.

Currently with swift 5 the easiest way to check if the player is playing or paused is to check the .timeControlStatus variable.

    var temp = '<tr><td>' + data[i].id + '</td>';
    temp+= '<td>' + data[i].name+ '</td>';

There is no error in the code, but the error is thrown due to the following:

 - Please check whether you have given Read-write permission to MS-Access database file.
 - The Database file where it is stored (say in Folder1) is read-only..? 

suppose you are stored the database (MS-Access file) in read only folder, while running your application the connection is not force-fully opened. Hence change the file permission / its containing folder permission like in C:\Program files all most all c drive files been set read-only so changing this permission solves this Problem.

The ConfigurationManager is not what you need to access your own settings.

To do this you should use

{YourAppName}.Properties.Settings.{settingName}

Some DBMSs will let you use an alias instead of having to repeat the entire expression.
Teradata is one such example.

I avoid ordinal position notation as recommended by Bill for reasons documented in this SO question.

The easy and robust alternative is to always repeat the expression in the GROUP BY clause.

1) Use it to ensure an ordered execution of callbacks:

var step1 = new Deferred();
var step2 = new Deferred().done(function() { return step1 });
var step3 = new Deferred().done(function() { return step2 });

step1.done(function() { alert("Step 1") });
step2.done(function() { alert("Step 2") });
step3.done(function() { alert("All done") });
//now the 3 alerts will also be fired in order of 1,2,3
//no matter which Deferred gets resolved first.

step2.resolve();
step3.resolve();
step1.resolve();

2) Use it to verify the status of the app:

var loggedIn = logUserInNow(); //deferred
var databaseReady = openDatabaseNow(); //deferred

jQuery.when(loggedIn, databaseReady).then(function() {
  //do something
});

I have also used a non-generic version, using the new keyword:

public interface IMetadata
{
    Type DataType { get; }

    object Data { get; }
}

public interface IMetadata<TData> : IMetadata
{
    new TData Data { get; }
}

Explicit interface implementation is used to allow both Data members:

public class Metadata<TData> : IMetadata<TData>
{
    public Metadata(TData data)
    {
       Data = data;
    }

    public Type DataType
    {
        get { return typeof(TData); }
    }

    object IMetadata.Data
    {
        get { return Data; }
    }

    public TData Data { get; private set; }
}

You could derive a version targeting value types:

public interface IValueTypeMetadata : IMetadata
{

}

public interface IValueTypeMetadata<TData> : IMetadata<TData>, IValueTypeMetadata where TData : struct
{

}

public class ValueTypeMetadata<TData> : Metadata<TData>, IValueTypeMetadata<TData> where TData : struct
{
    public ValueTypeMetadata(TData data) : base(data)
    {}
}

This can be extended to any kind of generic constraints.

Doing password checks on client side is unsafe especially when the password is hard coded.

The safest way is password checking on server side, but even then the password should not be transmitted plain text.

Checking the password client side is possible in a "secure way":

• The password needs to be hashed
• The hashed password is used as part of a new url

Say "abc" is your password so your md5 would be "900150983cd24fb0d6963f7d28e17f72" (consider salting!). Now build a url containing the hash (like http://yourdomain.com/90015...f72.html).

You need the following functions to do this in PHP:

strpos Find the position of the first occurrence of a substring in a string

strrpos Find the position of the last occurrence of a substring in a string

substr Return part of a string

Here's the signature of the substr function:

string substr ( string $string , int $start [, int $length ] )

The signature of the substring function (Java) looks a bit different:

string substring( int beginIndex, int endIndex )

substring (Java) expects the end-index as the last parameter, but substr (PHP) expects a length.

It's not hard, to get the desired length by the end-index in PHP:

$sub = substr($str, $start, $end - $start);

Here is the working code

$start = strpos($message, '-') + 1;
if ($req_type === 'RMT') {
    $pt_password = substr($message, $start);
}
else {
    $end = strrpos($message, '-');
    $pt_password = substr($message, $start, $end - $start);
}

The extend method for example in jQuery or PrototypeJS, copies all properties from the source to the destination object.

Now about the prototype property, it is a member of function objects, it is part of the language core.

Any function can be used as a constructor, to create new object instances. All functions have this prototype property.

When you use the new operator with on a function object, a new object will be created, and it will inherit from its constructor prototype.

For example:

function Foo () {
}
Foo.prototype.bar = true;

var foo = new Foo();

foo.bar; // true
foo instanceof Foo; // true
Foo.prototype.isPrototypeOf(foo); // true

If you already have "bash", "powershell" and "cmd" CLI's and have correct path settings then switching from one CLI to another can done by the following ways.

Ctrl + ' : Opens the terminal window with default CLI.

bash + enter : Switch from your default/current CLI to bash CLI.

powershell + enter : Switch from your default/current CLI to powershell CLI.

cmd + enter : Switch from your default/current CLI to cmd CLI.

I use Remote login with vnc-ltsp-config with GNOME Desktop Environment on CentOS 5.9. From experimenting today, I managed to get cut and paste working for the session and the login prompt (because I'm lazy and would rather copy and paste difficult passwords).

1. I created a file vncconfig.desktop in the /etc/xdg/autostart directory which enabled cut and paste during the session after login. The vncconfig process is run as the logged in user.

   [Desktop Entry]
   Name=No name
   Encoding=UTF-8
   Version=1.0
   Exec=vncconfig -nowin
   X-GNOME-Autostart-enabled=true
   

2. Added vncconfig -nowin & to the bottom of the file /etc/gdm/Init/Desktop which enabled cut and paste in the session during login but terminates after login. The vncconfig process is run as root.

3. Adding vncconfig -nowin & to the bottom of the file /etc/gdm/PostLogin/Desktop also enabled cut and paste during the session after login. The vncconfig process is run as root however.

This is how you should be using mysql_fetch_assoc():

$result = mysql_query($query);

while ($row = mysql_fetch_assoc($result)) {
    // Do stuff with $row
}

$result should be a resource. Even if the query returns no rows, $result is still a resource. The only time $result is a boolean value, is if there was an error when querying the database. In which case, you should find out what that error is by using mysql_error() and ensure that it can't happen. Then you don't have to hide from any errors.

You should always cover the base that errors may happen by doing:

if (!$result) {
    die(mysql_error());
}

At least then you'll be more likely to actually fix the error, rather than leave the users with a glaring ugly error in their face.

The problems are to do with your paths.

1. Make sure that the directory "E:\java resources\apache-maven-2.2.0\bin" is on your command search path.

2. Make sure that the JAVA_HOME variable refers to the home directory for your Java installation. If you are executing Java from "E:\Sun\SDK\jdk\bin", then the JAVA_HOME variable needs to point to "E:\Sun\SDK\jdk".

   NB: JAVA_HOME should NOT end with "\bin"¹.

3. Make sure that you haven't put a semicolon in the JAVA_HOME variable².

   NB: JAVA_HOME should be a single directory name, not "PATH-like" list of directory names separated by semicolons.

Also note that you could run into problems if you have ignored this advice in the Maven on Windows instructions about spaces in key pathnames.

"Maven, like many cross-platform tools, can encounter problems when there are space characters in important pathnames."

"You need to install the Java SDK (e.g. from Oracle's download site), and you should install it to a pathname without spaces, such as c:\j2se1.6."'

"You need to unpack the Maven distribution. Don't unpack it in the middle of your source code; pick some location (with no spaces in the path!) and unpack it there."

The simple remedy for this would be to reinstall Java or Maven in a different location so that there isn't a space in the path

^{1 - .... unless you have made an insane choice for the name for your installation location.}

^{2 - Apparently a common "voodoo" solution to Windows path problems is to whack a semicolon on the end. It is not recommended in general, absolutely does not work here.}

Just use the vector constructor.

std::vector<int>   data();
// Load Z elements into data so that Z > Y > X

std::vector<int>   sub(&data[100000],&data[101000]);

All you need to do is run

pip install /opt/mypackage

and pip will search /opt/mypackage for a setup.py, build a wheel, then install it.

The problem with using the -e flag for pip install as suggested in the comments and this answer is that this requires that the original source directory stay in place for as long as you want to use the module. It's great if you're a developer working on the source, but if you're just trying to install a package, it's the wrong choice.

Alternatively, you don't even need to download the repo from Github at all. pip supports installing directly from git repos using a variety of protocols including HTTP, HTTPS, and SSH, among others. See the docs I linked to for examples.

If your file is short (or even not extremely long), you can use the following snippet to replace text in place:

# Replace variables in file
with open('path/to/in-out-file', 'r+') as f:
    content = f.read()
    f.seek(0)
    f.truncate()
    f.write(content.replace('replace this', 'with this'))

It works perfectly.

I find the following tricks give between 2x and 4x speed increase versus the pandas method described above (i.e. pd.DatetimeIndex(dates).year etc.). The speed of [dt.year for dt in dates.astype(object)] I find to be similar to the pandas method. Also these tricks can be applied directly to ndarrays of any shape (2D, 3D etc.)

dates = np.arange(np.datetime64('2000-01-01'), np.datetime64('2010-01-01'))
years = dates.astype('datetime64[Y]').astype(int) + 1970
months = dates.astype('datetime64[M]').astype(int) % 12 + 1
days = dates - dates.astype('datetime64[M]') + 1

(One) Solution for Netbeans 7.1: Try a pull. This will probably also fail. Now have a look into the logs (they are usually shown now in the IDE). There's one/more line saying:

"Pull failed due to this file:"

Search that file, delete it (make a backup before). Usually it's a .gitignore file, so you will not delete code. Redo the push. Everything should work fine now.

You need DATE_ADD/DATE_SUB:

AND v.date > (DATE_SUB(CURDATE(), INTERVAL 2 MONTH))
AND v.date < (DATE_SUB(CURDATE(), INTERVAL 1 MONTH))

should work.

For the filestream:

//Check if the directory exists
if (!System.IO.Directory.Exists(@"C:\yourDirectory"))
{
    System.IO.Directory.CreateDirectory(@"C:\yourDirectory");
}

//Write the file
using (System.IO.StreamWriter outfile = new System.IO.StreamWriter(@"C:\yourDirectory\yourFile.txt"))
{
    outfile.Write(yourFileAsString);
}

The .Elements operation returns a LIST of XElements - but what you really want is a SINGLE element. Add this:

XElement Contacts = (from xml2 in XMLDoc.Elements("Contacts").Elements("Node")
                    where xml2.Element("ID").Value == variable
                    select xml2).FirstOrDefault();

This way, you tell LINQ to give you the first (or NULL, if none are there) from that LIST of XElements you're selecting.

While it's true that json is a built-in module, I also found that on an Ubuntu system with python-minimal installed, you DO have python but you can't do import json. And then I understand that you would try to install the module using pip!

If you have python-minimal you'll get a version of python with less modules than when you'd typically compile python yourself, and one of the modules you'll be missing is the json module. The solution is to install an additional package, called libpython2.7-stdlib, to install all 'default' python libraries.

sudo apt install libpython2.7-stdlib

And then you can do import json in python and it would work!

Building on the answer by Dejan, what you can do is import System.Web.Helpers .NET Framework assembly, then use the following function:

static string EscapeForJson(string s) {
  string quoted = System.Web.Helpers.Json.Encode(s);
  return quoted.Substring(1, quoted.Length - 2);
}

The Substring call is required, since Encode automatically surrounds strings with double quotes.

You need to use the overflow option, but with the following parameters:

.nav {
    max-height:300px;
    overflow-y:auto;  
}

Use overflow-y:auto; so the scrollbar only appears when the content exceeds the maximum height.

If you use overflow-y:scroll, the scrollbar will always be visible - on all .nav - regardless if the content exceeds the maximum heigh or not.

Presumably you want something that adapts itself to the content rather then the the opposite.

In theory, there's nothing preventing you from sending a request body in a GET request. The HTTP protocol allows it, but have no defined semantics, so it's up to you to document what exactly is going to happen when a client sends a GET payload. For instance, you have to define if parameters in a JSON body are equivalent to querystring parameters or something else entirely.

However, since there are no clearly defined semantics, you have no guarantee that implementations between your application and the client will respect it. A server or proxy might reject the whole request, or ignore the body, or anything else. The REST way to deal with broken implementations is to circumvent it in a way that's decoupled from your application, so I'd say you have two options that can be considered best practices.

The simple option is to use POST instead of GET as recommended by other answers. Since POST is not standardized by HTTP, you'll have to document how exactly that's supposed to work.

Another option, which I prefer, is to implement your application assuming the GET payload is never tampered with. Then, in case something has a broken implementation, you allow clients to override the HTTP method with the X-HTTP-Method-Override, which is a popular convention for clients to emulate HTTP methods with POST. So, if a client has a broken implementation, it can write the GET request as a POST, sending the X-HTTP-Method-Override: GET method, and you can have a middleware that's decoupled from your application implementation and rewrites the method accordingly. This is the best option if you're a purist.

On Linux

(tested in Ununtu KDE)

There is the option in the menu, under Edit > Lines > Auto Indent or press Cmd + Shift + p, search for Editor: Auto Indent by entering just "ai"

Note: In KDE ctrl-alt-l is already globally set for "lock screen" so better use ctrl-alt-i instead.

You can add a key mapping in Atom:

• Cmd + Shift + p, search for "Settings View: Show Keybindings"
• click on "your keymap file"

• Add a section there like this one:

   'atom-text-editor':
      'ctrl-alt-i': 'editor:auto-indent'
  

If the indention is not working, it can be a reason, that the file-ending is not recognized by Atom. Add the support for your language then, for example for "Lua" install the package "language-lua".

If a File is not recognized for your language:

• open the ~/.atom/config.cson file (by CTRL+SHIFT+p: type ``open config'')

• add/edit a customFileTypes section under core for example like the following:

  core:
    customFileTypes:
      "source.lua": [
        "conf"
      ]
      "text.html.php": [
        "thtml"
      ]
  

(You find the languages scope names ("source.lua", "text.html.php"...) in the language package settings see here)

Here is a modified version of CsabaS's answer, which accounts for explicit deny access rules. The function goes through all FileSystemAccessRules for a directory, and checks if the current user is in a role which has access to a directory. If no such roles are found or the user is in a role with denied access, the function returns false. To check read rights, pass FileSystemRights.Read to the function; for write rights, pass FileSystemRights.Write. If you want to check an arbitrary user's rights and not the current one's, substitute the currentUser WindowsIdentity for the desired WindowsIdentity. I would also advise against relying on functions like this to determine if the user can safely use the directory. This answer perfectly explains why.

    public static bool UserHasDirectoryAccessRights(string path, FileSystemRights accessRights)
    {
        var isInRoleWithAccess = false;

        try
        {
            var di = new DirectoryInfo(path);
            var acl = di.GetAccessControl();
            var rules = acl.GetAccessRules(true, true, typeof(NTAccount));

            var currentUser = WindowsIdentity.GetCurrent();
            var principal = new WindowsPrincipal(currentUser);
            foreach (AuthorizationRule rule in rules)
            {
                var fsAccessRule = rule as FileSystemAccessRule;
                if (fsAccessRule == null)
                    continue;

                if ((fsAccessRule.FileSystemRights & accessRights) > 0)
                {
                    var ntAccount = rule.IdentityReference as NTAccount;
                    if (ntAccount == null)
                        continue;

                    if (principal.IsInRole(ntAccount.Value))
                    {
                        if (fsAccessRule.AccessControlType == AccessControlType.Deny)
                            return false;
                        isInRoleWithAccess = true;
                    }
                }
            }
        }
        catch (UnauthorizedAccessException)
        {

You need to roll your own method to eliminate the files you don't want.

This isn't easy with the built in tools, but you could use RegExKit Lite to assist with finding the elements in the returned array you are interested in. According to the release notes this should work in both Cocoa and Cocoa-Touch applications.

Here's the demo code I wrote up in about 10 minutes. I changed the < and > to " because they weren't showing up inside the pre block, but it still works with the quotes. Maybe somebody who knows more about formatting code here on StackOverflow will correct this (Chris?).

This is a "Foundation Tool" Command Line Utility template project. If I get my git daemon up and running on my home server I'll edit this post to add the URL for the project.

int main (int argc, const char * argv[])
{
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    // insert code here...
    MTFileMatcher* matcher = [[[MTFileMatcher alloc] init] autorelease];
    [matcher getFilesMatchingRegEx:@"^.+\\.[Jj][Pp][Ee]?[Gg]$" forPath:[@"~/Pictures" stringByExpandingTildeInPath]];

    [pool drain];
    return 0;

    NSEnumerator* itr = [filesAtPath objectEnumerator];

The problem is due to the input element box model. I just recently found a nice solution to the issue when trying to keep my input at 100% for mobile devices.

Wrap your input with another element, a div for example. Then apply the styling you want for your input to that the wrapper div. For example:

<div class="input-wrapper">
 <input type="text" />
</div>

.input-wrapper {
    border-raius:5px;
    padding:10px;
}
.input-wrapper input[type=text] {
    width:100%;
    font-size:16px;
}

Give .input-wrapper rounded corner padding etc, whatever you want for your input, then give the input width 100%. You have your input padded nicely with a border etc but without the annoying overflow!

This way you get the intersection of two lists and also get the common duplicates.

>>> from collections import Counter
>>> a = Counter([1,2,3,4,5])
>>> b = Counter([1,3,5,6])
>>> a &= b
>>> list(a.elements())
[1, 3, 5]

Try this:

x = a > b and 10 or 11

This is a sample of execution:

>>> a,b=5,7
>>> x = a > b and 10 or 11
>>> print x
11

So by default you can open CMD and write

java -jar jenkins.war

But if your port 8080 is already is in use,so you have to change the Jenkins port number, so for that open Jenkins folder in Program File and open Jenkins.XML file and change the port number such as 8088

Now Open CMD and write

java -jar jenkins.war --httpPort=8088

It looks like you are running into a bug in the way NetBeans 6.8 creates the jar for a Java Library Project.

The issue implies that there is a work-around.

I have not been able to verify that with NB 6.8 and/or NetBeans 6.9-dev...

You may want to register with the NetBeans.org website/issue tracker and update the issue and add your 'vote'.

Testing¹ reveals that Lightsail instances in fact are EC2 instances, from the t2 class of burstable instances.

EC2, of course, has many more instance families and classes other than the t2, almost all of which are more "powerful" (or better equipped for certain tasks) than these, but also much more expensive. But for meaningful comparisons, the 512 MiB Lightsail instance appears to be completely equivalent in specifications to the similarly-priced t2.nano, the 1GiB is a t2.micro, the 2 GiB is a t2.small, etc.

Lightsail is a lightweight, simplified product offering -- hard disks are fixed size EBS SSD volumes, instances are still billable when stopped, security group rules are much less flexible, and only a very limited subset of EC2 features and options are accessible.

It also has a dramatically simplified console, and even though the machines run in EC2, you can't see them in the EC2 section of the AWS console. The instances run in a special VPC, but this aspect is also provisioned automatically, and invisible in the console. Lightsail supports optionally peering this hidden VPC with your default VPC in the same AWS region, allowing Lightsail instances to access services like EC2 and RDS in the default VPC within the same AWS account.²

Bandwidth is unlimited, but of course free bandwidth is not -- however, Lightsail instances do include a significant monthly bandwidth allowance before any bandwidth-related charges apply.³ Lightsail also has a simplified interface to Route 53 with limited functionality.

But if those sound like drawbacks, they aren't. The point of Lightsail seems to be simplicity. The flexibility of EC2 (and much of AWS) leads inevitably to complexity. The target market for Lightsail appears to be those who "just want a simple VPS" without having to navigate the myriad options available in AWS services like EC2, EBS, VPC, and Route 53. There is virtually no learning curve, here. You don't even technically need to know how to use SSH with a private key -- the Lightsail console even has a built-in SSH client -- but there is no requirement that you use it. You can access these instances normally, with a standard SSH client.

¹Lightsail instances, just like "regular" EC2 (VPC and Classic) instances, have access to the instance metadata service, which allows an instance to discover things about itself, such as its instance type and availability zone. Lightsail instances are identified in the instance metadata as t2 machines.

²The Lightsail docs are not explicit about the fact that peering only works with your Default VPC, but this appears to be the case. If your AWS account was created in 2013 or before, then you may not actually have a VPC with the "Default VPC" designation. This can be resolved by submitting a support request, as I explained in Can't establish VPC peering connection from Amazon Lightsail (at Server Fault).

³The bandwidth allowance applies to both inbound and outbound traffic; after this total amount of traffic is exceeded, inbound traffic continues to be free, but outbound traffic becomes billable. See "What does data transfer cost?" in the Lightsail FAQ.

Use

document.getElementById("file-id").files[0].name; 

instead of

document.getElementById('file-id').value

In jQuery you can trigger a click like this:

$('#foo').trigger('click');

If you want to do the same using prototype, it looks like this:

$('foo').simulate('click');

As the previous answers saids, try to move the state to a top component and modify the state through callbacks passed to it's children.

In case that you really need to access to a child state that is declared as a functional component (hooks) you can declare a ref in the parent component, then pass it as a ref attribute to the child but you need to use React.forwardRef and then the hook useImperativeHandle to declare a function you can call in the parent component.

Take a look at the following example:

const Parent = () => {
    const myRef = useRef();
    return <Child ref={myRef} />;
}

const Child = React.forwardRef((props, ref) => {
    const [myState, setMyState] = useState('This is my state!');
    useImperativeHandle(ref, () => ({getMyState: () => {return myState}}), [myState]);
})

Then you should be able to get myState in the Parent component by calling: myRef.current.getMyState();

LayoutInflater is used to generate dynamic views of the XML for the ListView item or in onCreateView of the fragment.

ConvertView is basically used to recycle the views which are not in the view currently. Say you have a scrollable ListView. On scrolling down or up, the convertView gives the view which was scrolled. This reusage saves memory.

The parent parameter of the getView() method gives a reference to the parent layout which has the listView. Say you want to get the Id of any item in the parent XML you can use:

ViewParent nv = parent.getParent();

while (nv != null) {

    if (View.class.isInstance(nv)) {
        final View button = ((View) nv).findViewById(R.id.remove);
        if (button != null) {
            // FOUND IT!
            // do something, then break;
            button.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    Log.d("Remove", "Remove clicked");

                    ((Button) button).setText("Hi");
                }
            });
        }
        break;
    }

 }

Because it's more common to call range(0, 10) which returns [0,1,2,3,4,5,6,7,8,9] which contains 10 elements which equals len(range(0, 10)). Remember that programmers prefer 0-based indexing.

Also, consider the following common code snippet:

for i in range(len(li)):
    pass

Could you see that if range() went up to exactly len(li) that this would be problematic? The programmer would need to explicitly subtract 1. This also follows the common trend of programmers preferring for(int i = 0; i < 10; i++) over for(int i = 0; i <= 9; i++).

If you are calling range with a start of 1 frequently, you might want to define your own function:

>>> def range1(start, end):
...     return range(start, end+1)
...
>>> range1(1, 10)
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Good way to do this is to use mkdirp module.

$ npm install mkdirp

Use it to run function that requires the directory. Callback is called after path is created or if path did already exists. Error err is set if mkdirp failed to create directory path.

var mkdirp = require('mkdirp');
mkdirp('/tmp/some/path/foo', function(err) { 

    // path exists unless there was an error

});

I can't say this is the most bulletproof or portable solution, but it works for my testing scripts:

.output /tmp/temp_drop_tables.sql
select 'drop table ' || name || ';' from sqlite_master where type = 'table';
.output stdout
.read /tmp/temp_drop_tables.sql
.system rm /tmp/temp_drop_tables.sql

This bit of code redirects output to a temporary file, constructs the 'drop table' commands that I want to run (sending the commands to the temp file), sets output back to standard out, then executes the commands from the file, and finally removes the file.

There is no such limit on the string length. To be certain, I just tested to create a string containing 60 megabyte.

The problem is likely that you are sending the data in a GET request, so it's sent in the URL. Different browsers have different limits for the URL, where IE has the lowest limist of about 2 kB. To be safe, you should never send more data than about a kilobyte in a GET request.

To send that much data, you have to send it in a POST request instead. The browser has no hard limit on the size of a post, but the server has a limit on how large a request can be. IIS for example has a default limit of 4 MB, but it's possible to adjust the limit if you would ever need to send more data than that.

Also, you shouldn't use += to concatenate long strings. For each iteration there is more and more data to move, so it gets slower and slower the more items you have. Put the strings in an array and concatenate all the items at once:

var items = $.map(keys, function(item, i) {
  var value = $("#value" + (i+1)).val().replace(/"/g, "\\\"");
  return
    '{"Key":' + '"' + Encoder.htmlEncode($(this).html()) + '"' + ",'+
    '" + '"Value"' + ':' + '"' + Encoder.htmlEncode(value) + '"}';
});
var jsonObj =
  '{"code":"' + code + '",'+
  '"defaultfile":"' + defaultfile + '",'+
  '"filename":"' + currentFile + '",'+
  '"lstResDef":[' + items.join(',') + ']}';

I ran into this problem, which resolved itself after I stopped using a proxy. Maybe CloudFront is blacklisting some IPs.

When you are on a project page, you can press the 'Download ZIP' button which is located under the "Clone or Download" drop down:

This allows you to download the most recent version of the code as a zip archive.

If you aren't seeing that button, it is likely because you aren't on the main project page. To get there, click on the left-most tab labeled "<> Code".

I was looking for a similar problem and found a better approach of doing this. So here it goes.

You can simply put the following line on the redirection page (say page1.php).

header("Location: URL", TRUE, 307); // Replace URL with to be redirected URL, e.g. final.php

I need this to redirect POST requests for REST API calls. This solution is able to redirect with post data as well as custom header values.

Here is the reference link.

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

You must create a migration, where you will specify default value for a new field, since you don't want it to be null. If null is not required, simply add null=True and create and run migration.

If dt is your datetime column, then

For 1:

SUBSTRING(CONVERT(varchar, dt, 13), 1, 2)
    + UPPER(SUBSTRING(CONVERT(varchar, dt, 13), 4, 3))

For 2:

SUBSTRING(CONVERT(varchar, dt, 100), 13, 2)
    + SUBSTRING(CONVERT(varchar, dt, 100), 16, 3)

As others have mentioned, you could use a comparison function, but you can also overload the < operator and the default less<T> functor will work as well:

struct data {
    string word;
    int number;
    bool operator < (const data& rhs) const {
        return word.size() < rhs.word.size();
    }
};

Then it's just:

std::sort(info.begin(), info.end());

Edit

As James McNellis pointed out, sort does not actually use the less<T> functor by default. However, the rest of the statement that the less<T> functor will work as well is still correct, which means that if you wanted to put struct datas into a std::map or std::set this would still work, but the other answers which provide a comparison function would need additional code to work with either.

Use bootstrap's .form-group class. Like this in your case:

<div class="col-md-6 form-group"></div>
<div class="col-md-6 form-group"></div>

You could extend the javascript Date object like this

Date.prototype.addDays = function(days) {
    this.setDate(this.getDate() + parseInt(days));
    return this;
};

and in your javascript code you could call

var currentDate = new Date();
// to add 4 days to current date
currentDate.addDays(4);

Use vertical-align:top; for the element you want at the top, as I have demonstrated on your jsfiddle.

try to write a shell script named run.sh in your project foler

#!/bin/bash
./YOUR_EXECUTIVE_FILE
...AND OTHER THING

and make a Build System to compile and execute it:

{
      "shell_cmd": "make all && ./run.sh"
}

don't forget $chmod +x run.sh

do one thing and do it well:)

As you see in an error UseCalls.java:27: error: cannot find symbol return String.parseString(input); there is no method parseString in String class. There is no need to parse it as long as JOptionPane.showInputDialog(prompt); already returns a string.

The code that you looked at is not ideal. You should either:

1. Catch the exception and handle it; in which case the throws is unnecesary.

2. Remove the try/catch; in which case the Exception will be handled by a calling method.

3. Catch the exception, possibly perform some action and then rethrow the exception (not just the message)

In Linux or MacOS you can use:

date +%s

where

• +%s, seconds since 1970-01-01 00:00:00 UTC. (GNU Coreutils 8.24 Date manual)

Example output now 1454000043.

if (code.indexOf("ST1")>=0) { location = "stoke central"; }

Package

I used html-pdf

Easy to use and allows not only to save pdf as file, but also pipe pdf content to a WriteStream (so I could stream it directly to Google Storage to save there my reports).

Using css + images

It takes css into account. The only problem I faced - it ignored my images. The solution I found was to replace url in src attrribute value by base64, e.g.

<img src="data:image/png;base64,iVBOR...kSuQmCC">

You can do it with your code or to use one of online converters, e.g. https://www.base64-image.de/

Compile valid html code from html fragment + css

1. I had to get a fragment of my html document (I just appiled .html() method on jQuery selector).
2. Then I've read the content of the relevant css file.

Using this two values (stored in variables html and css accordingly) I've compiled a valid html code using Template string

var htmlContent = `
<!DOCTYPE html>
<html>
  <head>
    <style>
      ${css}
    </style>
  </head>
  <body id=direct-sellers-bill>
    ${html}
  </body>
</html>`

and passed it to create method of html-pdf.

Make sure that your package is installed in your $GOPATH directory or already inside your workspace/package.

For example: if your $GOPATH = "c:\go", make sure that the package inside C:\Go\src\pkgName

Sometimes, even when the file is in the right directory, there is still the "file not found" exception. One thing you could do is to drop the text file inside eclipse, where your classes are, on the left side. It is going to ask you if you want to copy, click yes. Sometimes it helps.

ALL_CONSTRAINTS describes constraint definitions on tables accessible to the current user.

DBA_CONSTRAINTS describes all constraint definitions in the database.

USER_CONSTRAINTS describes constraint definitions on tables in the current user's schema

Select CONSTRAINT_NAME,CONSTRAINT_TYPE ,TABLE_NAME ,STATUS from 
USER_CONSTRAINTS;

I also had the issue of parsing and using JSON objects in C#. I checked the dynamic type with some libraries, but the issue was always checking if a property exists.

In the end, I stumbled upon this web page, which saved me a lot of time. It automatically creates a strongly typed class based on your JSON data, that you will use with the Newtonsoft library, and it works perfectly. It also works with languages other than C#.

It is:

if [ $# -eq 0 ]
  then
    echo "No arguments supplied"
fi

The $# variable will tell you the number of input arguments the script was passed.

Or you can check if an argument is an empty string or not like:

if [ -z "$1" ]
  then
    echo "No argument supplied"
fi

The -z switch will test if the expansion of "$1" is a null string or not. If it is a null string then the body is executed.

You might like the function GetInfoFromClosedFile()

Edit: Since the above link does not seem to work anymore, I am adding alternate link 1 and alternate link 2 + code:

Private Function GetInfoFromClosedFile(ByVal wbPath As String, _
    wbName As String, wsName As String, cellRef As String) As Variant
Dim arg As String
    GetInfoFromClosedFile = ""
    If Right(wbPath, 1) <> "" Then wbPath = wbPath & ""
    If Dir(wbPath & "" & wbName) = "" Then Exit Function
    arg = "'" & wbPath & "[" & wbName & "]" & _
        wsName & "'!" & Range(cellRef).Address(True, True, xlR1C1)
    On Error Resume Next
    GetInfoFromClosedFile = ExecuteExcel4Macro(arg)
End Function

I see two problems:

DOUBLE(10) precision definitions need a total number of digits, as well as a total number of digits after the decimal:

DOUBLE(10,8) would make be ten total digits, with 8 allowed after the decimal.

Also, you'll need to specify your id column as a key :

CREATE TABLE transactions( 
id int NOT NULL AUTO_INCREMENT, 
location varchar(50) NOT NULL, 
description varchar(50) NOT NULL, 
category varchar(50) NOT NULL, 
amount double(10,9) NOT NULL, 
type varchar(6) NOT NULL,  
notes varchar(512), 
receipt int(10), 
PRIMARY KEY(id) );

The issue I had was also with serialization. The cause was some of my DTO/business classes and properties were renamed or deleted without updating the service reference. I'm surprised I didn't get a contract filter mismatch error instead. But updating the service ref fixed the error for me (same error as OP).

FYI, I put together a JSFiddle of this using the $cookieStore, two controllers, a $rootScope, and AngularjS 1.0.6. It's on JSFifddle as http://jsfiddle.net/krimple/9dSb2/ as a base if you're messing around with this...

The gist of it is:

Javascript

var myApp = angular.module('myApp', ['ngCookies']);

myApp.controller('CookieCtrl', function ($scope, $rootScope, $cookieStore) {
    $scope.bump = function () {
        var lastVal = $cookieStore.get('lastValue');
        if (!lastVal) {
            $rootScope.lastVal = 1;
        } else {
            $rootScope.lastVal = lastVal + 1;
        }
        $cookieStore.put('lastValue', $rootScope.lastVal);
    }
});

myApp.controller('ShowerCtrl', function () {
});

HTML

<div ng-app="myApp">
    <div id="lastVal" ng-controller="ShowerCtrl">{{ lastVal }}</div>
    <div id="button-holder" ng-controller="CookieCtrl">
        <button ng-click="bump()">Bump!</button>
    </div>
</div>

11-25 14:47:01.681: ERROR/AndroidRuntime(302): blah blah...requires android.permission.CALL_PHONE

^ The answer lies in the exception output "requires android.permission.CALL_PHONE" :)

I just restarted Visual Studio and did IISRESET which solved the problem.

SQlite3 has a method named row_factory. This method would allow you to access the values by column name.

Check for logs at /var/log/mongodb/mongod.log and try to deduce the error. In my case it was

Failed to unlink socket file /tmp/mongodb-27017.sock errno:1 Operation not permitted

Deleted /tmp/mongodb-27017.sock and it worked.

Get-Content grabs data and dumps it into an array, line by line. Assuming there aren't other special requirements than you listed, you could just save your content into a variable?

$file = Get-Content c:\file\whatever.txt

Running just $file will return the full contents. Then you can just do $file.Count (because arrays already have a count method built in) to get the total # of lines.

Hope this helps! I'm not a scripting wiz, but this seemed easier to me than a lot of the stuff above.

I have found my key password in below path

Project\.gradle\2.14.1\taskArtifacts\taskArtifacts.bin open the file and search with the part of the password that you remember. You will found it definitely.

Also, You can refer this answer stackoverflow.com/a/43007357/7089151

Just pass var2 as an extra argument to one of the apply functions.

mylist <- list(a=1,b=2,c=3)
myfxn <- function(var1,var2){
  var1*var2
}
var2 <- 2

sapply(mylist,myfxn,var2=var2)

This passes the same var2 to every call of myfxn. If instead you want each call of myfxn to get the 1st/2nd/3rd/etc. element of both mylist and var2, then you're in mapply's domain.

Erase the module that can't be initialized and reinstall it.

Notice: This is for MySQLdb module in Python.

For a SELECT statement, there shouldn't be an exception for an empty recordset. Just an empty list ([]) for cursor.fetchall() and None for cursor.fetchone().

For any other statement, e.g. INSERT or UPDATE, that doesn't return a recordset, you can neither call fetchall() nor fetchone() on the cursor. Otherwise, an exception will be raised.

There's one way to distinguish between the above two types of cursors:

def yield_data(cursor):
    while True:
        if cursor.description is None:
            # No recordset for INSERT, UPDATE, CREATE, etc
            pass
        else:
            # Recordset for SELECT, yield data
            yield cursor.fetchall()
            # Or yield column names with
            # yield [col[0] for col in cursor.description]

        # Go to the next recordset
        if not cursor.nextset():
            # End of recordsets
            return

Not pretty. Definitely not pretty:

ls $Env:windir\Microsoft.NET\Framework | ? { $_.PSIsContainer } | select -exp Name -l 1

This may or may not work. But as far as the latest version is concerned this should be pretty reliable, as there are essentially empty folders for old versions (1.0, 1.1) but not newer ones – those only appear once the appropriate framework is installed.

Still, I suspect there must be a better way.

Unfortunately I find none of the existing answers particularly satisfying.

Here is a straightforward and complete Python 3 solution, using the csv module.

import csv

with open('../resources/temp_in.csv', newline='') as f:
    reader = csv.reader(f, skipinitialspace=True)
    rows = list(reader)

print(rows)

Notice the skipinitialspace=True argument. This is necessary since, unfortunately, OP's CSV contains whitespace after each comma.

Output:

[['This is the first line', 'Line1'], ['This is the second line', 'Line2'], ['This is the third line', 'Line3']]

In the solutions in previous answers selection is stopped, but the user still thinks you can select text because the cursor still changes. To keep it static, you'll have to set your CSS cursor:

.noselect {_x000D_
    cursor: default;_x000D_
    -webkit-touch-callout: none;_x000D_
    -webkit-user-select: none;_x000D_
    -khtml-user-select: none;_x000D_
    -moz-user-select: none;_x000D_
    -ms-user-select: none;_x000D_
    user-select: none;_x000D_
}

<p>_x000D_
  Selectable text._x000D_
</p>_x000D_
<p class="noselect">_x000D_
  Unselectable text._x000D_
</p>

This will make your text totally flat, like it would be in a desktop application.

Arrays in Java start indexing at 0. So in your example you are referring to an element that is outside the array by one.

It should probably be something like freq[Global.iParameter[2]-1]=false;

You would need to loop through the array to initialize all of it, this line only initializes the last element.

Actually, I'm pretty sure that false is default for booleans in Java, so you might not need to initialize at all.

Best Regards

I doubt there is one... It depends on browser, on printer (physical max dpi) and its driver, on paper size as you point out (and I might want to print on B5 paper too...), on settings (landscape or portrait?), plus you often can change the scale (percentage), etc.
Let the users tweak their settings...

I am not sure what you mean with remove all events. Remove all handlers for a specific type of event or all event handlers for one type?

Remove all event handlers

If you want to remove all event handlers (of any type), you could clone the element and replace it with its clone:

var clone = element.cloneNode(true);

Note: This will preserve attributes and children, but it will not preserve any changes to DOM properties.

Remove "anonymous" event handlers of specific type

The other way is to use removeEventListener() but I guess you already tried this and it didn't work. Here is the catch:

Calling addEventListener to an anonymous function creates a new listener each time. Calling removeEventListener to an anonymous function has no effect. An anonymous function creates a unique object each time it is called, it is not a reference to an existing object though it may call one. When adding an event listener in this manner be sure it is added only once, it is permanent (cannot be removed) until the object it was added to, is destroyed.

You are essentially passing an anonymous function to addEventListener as eventReturner returns a function.

You have two possibilities to solve this:

1. Don't use a function that returns a function. Use the function directly:

    function handler() {
        dosomething();
    }
   
    div.addEventListener('click',handler,false);
   

2. Create a wrapper for addEventListener that stores a reference to the returned function and create some weird removeAllEvents function:

    var _eventHandlers = {}; // somewhere global
   
    const addListener = (node, event, handler, capture = false) => {
      if (!(event in _eventHandlers)) {
        _eventHandlers[event] = []
      }
      // here we track the events and their nodes (note that we cannot
      // use node as Object keys, as they'd get coerced into a string
      _eventHandlers[event].push({ node: node, handler: handler, capture: capture })
      node.addEventListener(event, handler, capture)
    }
   
    const removeAllListeners = (targetNode, event) => {
      // remove listeners from the matching nodes
      _eventHandlers[event]
        .filter(({ node }) => node === targetNode)
        .forEach(({ node, handler, capture }) => node.removeEventListener(event, handler, capture))
   
      // update _eventHandlers global
      _eventHandlers[event] = _eventHandlers[event].filter(
        ({ node }) => node !== targetNode,
      )
    }
   

And then you could use it with:

    addListener(div, 'click', eventReturner(), false)
    // and later
    removeAllListeners(div, 'click')

DEMO

Note: If your code runs for a long time and you are creating and removing a lot of elements, you would have to make sure to remove the elements contained in _eventHandlers when you destroy them.

You could do it if template is a react component.

Template.js

var React = require('react');

var Template = React.createClass({
    render: function(){
        return (<div>Mi HTML</div>);
    }
});

module.exports = Template;

MainComponent.js

var React = require('react');
var ReactDOM = require('react-dom');
var injectTapEventPlugin = require("react-tap-event-plugin");
var Template = require('./Template');

//Needed for React Developer Tools
window.React = React;

//Needed for onTouchTap
//Can go away when react 1.0 release
//Check this repo:
//https://github.com/zilverline/react-tap-event-plugin
injectTapEventPlugin();

var MainComponent = React.createClass({
    render: function() {
        return(
            <Template/>
        );
    }
});

// Render the main app react component into the app div.
// For more details see: https://facebook.github.io/react/docs/top-level-api.html#react.render
ReactDOM.render(
  <MainComponent />,
  document.getElementById('app')
 );

And if you are using Material-UI, for compatibility use Material-UI Components, no normal inputs.

I've seen three results to a ping - The one we "want" where the IP replies, "Host Unreachable" and "timed out" (not sure of exact wording).

The first two return ERRORLEVEL of 0.

Timeout returns ERRORLEVEL of 1.

Are the other results and error levels that might be returned? (Besides using an invalid switch which returns the allowable switches and an errorlevel of 1.)

Apparently Host Unreachable can use one of the previously posted methods (although it's hard to figure out when someone replies which case they're writing code for) but does the timeout get returned in a similar manner that it can be parsed?

In general, how does one know what part of the results of the ping can be parsed? (Ie, why might Sent and/or Received and/or TTL be parseable, but not host unreachable?

Oh, and iSid, maybe there aren't many upvotes because the people that read this don't have enough points. So they get their question answered (or not) and leave.

I wasn't posting the above as an answer. It should have been a comment but I didn't see that choice.

Dynamic Programming

Definition

Dynamic programming (DP) is a general algorithm design technique for solving problems with overlapping sub-problems. This technique was invented by American mathematician “Richard Bellman” in 1950s.

Key Idea

The key idea is to save answers of overlapping smaller sub-problems to avoid recomputation.

Dynamic Programming Properties

• An instance is solved using the solutions for smaller instances.
• The solutions for a smaller instance might be needed multiple times, so store their results in a table.
• Thus each smaller instance is solved only once.
• Additional space is used to save time.

When using GetAsync with the HttpClient you can add the authorization headers like so:

httpClient.DefaultRequestHeaders.Authorization 
                         = new AuthenticationHeaderValue("Bearer", "Your Oauth token");

This does add the authorization header for the lifetime of the HttpClient so is useful if you are hitting one site where the authorization header doesn't change.

Here is an detailed SO answer

I don't believe this is possible. I believe you have to clone that remote repo locally and perform git fetch on it before you can issue a git log against it.

<div style="text-align: center; border-top: 1px solid black">
  <div style="display: inline-block; position: relative; top: -10px; background-color: white; padding: 0px 10px">text</div>
</div>

This is exactly how it worked for me. For some reason the above code failed.

This one runs a check every 3 minutes for any files in there and auto moves it to the destination folder. If you need to be prompted for conflicts then change the /y to /-y

:backup
move /y "D:\Dropbox\Dropbox\Camera Uploads\*.*" "D:\Archive\Camera Uploads\"
timeout 360
goto backup

I found the solution. In the manifest file of the application I found the package name: com.package.address and the name of the main activity which I want to launch: MainActivity The following code starts this application:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("com.package.address","com.package.address.MainActivity"));
startActivity(intent);

See this example in the MDN.

If you need to define multiple Errors (test the code here!):

function createErrorType(name, initFunction) {
    function E(message) {
        this.message = message;
        if (Error.captureStackTrace)
            Error.captureStackTrace(this, this.constructor);
        else
            this.stack = (new Error()).stack;
        initFunction && initFunction.apply(this, arguments);
    }
    E.prototype = Object.create(Error.prototype);
    E.prototype.name = name;
    E.prototype.constructor = E;
    return E;
}
var InvalidStateError = createErrorType(
    'InvalidStateError',
    function (invalidState, acceptedStates) {
        this.message = 'The state ' + invalidState + ' is invalid. Expected ' + acceptedStates + '.';
    });

var error = new InvalidStateError('foo', 'bar or baz');
function assert(condition) { if (!condition) throw new Error(); }
assert(error.message);
assert(error instanceof InvalidStateError);  
assert(error instanceof Error); 
assert(error.name == 'InvalidStateError');
assert(error.stack);
error.message;

Code is mostly copied from: What's a good way to extend Error in JavaScript?

Try swich fetchType from LAZY to EAGER

...
@OneToMany(fetch=FetchType.EAGER)
private Set<NodeValue> nodeValues;
...

But in this case your app will fetch data from DB anyway. If this query very hard - this may impact on performance. More here: https://docs.oracle.com/javaee/6/api/javax/persistence/FetchType.html

==> 73

A common idiom to change every element of a list looks like this:

for i in range(len(L)):
    item = L[i]
    # ... compute some result based on item ...
    L[i] = result

This can be rewritten using enumerate() as:

for i, item in enumerate(L):
    # ... compute some result based on item ...
    L[i] = result

See enumerate.

Below query will provide exactly the same result as given in the desired response:

db.books.aggregate([
    {
        $group: {
            _id: { addresses: "$addr", books: "$book" },
            num: { $sum :1 }
        }
    },
    {
        $group: {
            _id: "$_id.addresses",
            bookCounts: { $push: { bookName: "$_id.books",count: "$num" } }
        }
    },
    {
        $project: {
            _id: 1,
            bookCounts:1,
            "totalBookAtAddress": {
                "$sum": "$bookCounts.count"
            }
        }

bool is just a macro that expands to _Bool. You can use _Bool with no #include very much like you can use int or double; it is a C99 keyword.

The macro is defined in <stdbool.h> along with 3 other macros.

The macros defined are

• bool: macro expands to _Bool
• false: macro expands to 0

Here is a version that works in all modern browsers. The key is using appearance:none which removes the default formatting. Since all of the formatting is gone, you have to add back in the arrow that visually differentiates the select from the input. Note: appearance is not supported in IE.

Working example: https://jsfiddle.net/gs2q1c7p/

My Oracle is a bit rusty, but I think this would work:

SELECT * FROM TableA
WHERE ROWID IN ( SELECT MAX(ROWID) FROM TableA GROUP BY Language )

You can also use AWK which can give you more flexibility to handle the file

awk '{ print "chmod 755 "$0"" | "/bin/sh"}' file.txt

if your file has a field separator like:

field1,field2,field3

To get only the first field you do

awk -F, '{ print "chmod 755 "$1"" | "/bin/sh"}' file.txt

You can check more details on GNU Documentation https://www.gnu.org/software/gawk/manual/html_node/Very-Simple.html#Very-Simple

Try this:-

<!DOCTYPE html> 
<html> 
<head> 
    <meta charset="ISO-8859-1"> 
    <title>Online Student Portal</title> 
</head> 
<body> 
    <form action="">
         <input type="button" value="Add Students" onclick="window.location.href='Students.html';"/>
         <input type="button" value="Add Courses" onclick="window.location.href='Courses.html';"/>
         <input type="button" value="Student Payments" onclick="window.location.href='Payment.html';"/>
    </form> 
</body> 
</html>

I think it will be easier using syntax-based query:

var entryPoint = (from ep in dbContext.tbl_EntryPoint
                 join e in dbContext.tbl_Entry on ep.EID equals e.EID
                 join t in dbContext.tbl_Title on e.TID equals t.TID
                 where e.OwnerID == user.UID
                 select new {
                     UID = e.OwnerID,
                     TID = e.TID,
                     Title = t.Title,
                     EID = e.EID
                 }).Take(10);

And you should probably add orderby clause, to make sure Top(10) returns correct top ten items.

Highlight "B1" and press F4. This will lock the cell.

Now you can drag it around and it will not change. The principle is simple. It adds a dollar sign before both coordinates. A dollar sign in front of a coordinate will lock it when you copy the formula around. You can have partially locked coordinates and fully locked coordinates.

For me this issue occured in a following >simplified< example. And I was also able to solve it (hopefully with a correct solution):

old code with warning:

def update_old_dataframe(old_dataframe, new_dataframe):
    for new_index, new_row in new_dataframe.iterrorws():
        old_dataframe.loc[new_index] = update_row(old_dataframe.loc[new_index], new_row)

def update_row(old_row, new_row):
    for field in [list_of_columns]:
        # line with warning because of chain indexing old_dataframe[new_index][field]
        old_row[field] = new_row[field]  
    return old_row

This printed the warning for the line old_row[field] = new_row[field]

Since the rows in update_row method are actually type Series, I replaced the line with:

old_row.at[field] = new_row.at[field]

i.e. method for accessing/lookups for a Series. Eventhough both works just fine and the result is same, this way I don't have to disable the warnings (=keep them for other chain indexing issues somewhere else).

I hope this may help someone.

I read this article (https://www.beyondjava.net/elvis-operator-aka-safe-navigation-javascript-typescript) and modified the solution using Proxies.

function safe(obj) {
    return new Proxy(obj, {
        get: function(target, name) {
            const result = target[name];
            if (!!result) {
                return (result instanceof Object)? safe(result) : result;
            }
            return safe.nullObj;
        },
    });
}

safe.nullObj = safe({});
safe.safeGet= function(obj, expression) {
    let safeObj = safe(obj);
    let safeResult = expression(safeObj);

    if (safeResult === safe.nullObj) {
        return undefined;
    }
    return safeResult;
}

You call it like this:

safe.safeGet(example, (x) => x.foo.woo)

The result will be undefined for an expression that encounters null or undefined along its path. You could go wild and modify the Object prototype!

Object.prototype.getSafe = function (expression) {
    return safe.safeGet(this, expression);
};

example.getSafe((x) => x.foo.woo);

I would also highly recommend Adminer - http://www.adminer.org/

It is much faster than phpMyAdmin, does less funky iframe stuff, and supports both MySQL and PostgreSQL.

In the Storyboard, select the UITableView, and modify the property Style from Plain to Grouped.

Able to achieve this by adding a global tap gesture recognizer to the window property in the AppDelegate.

This was a very catch all approach and might not be the desired solution for some but it worked for me. Please let me know if there any pitfalls to this solution.

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        // Globally dismiss the keyboard when the "background" is tapped.
        window?.addGestureRecognizer(
            UITapGestureRecognizer(
              target: window, 
              action: #selector(UIWindow.endEditing(_:))
            )
        )

        return true
    }
}

If you are doing it in eclipse, there are a few quick notes that if you are hovering your mouse over a class in your script, it will show a focus dialogue that says hit f2 for focus.

for computer apps, use ImageIcon. and for the path say,

ImageIcon thisImage = new ImageIcon("images/youpic.png");

specify the folder( images) then seperate with / and add the name of the pic file.

I hope this is helpful. If someone else posted it, I didn't read through. So...yea.. thought reinforcement.

If I understand well, you want to Join ScheduleRequest with User and apply the in clause to the userName property of the entity User.

I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join part (because it handles the Join logic outside the Criteria Query).

List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
    myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);

In order to write more type-safe code you could also use Metamodel by replacing this line:

Expression<String> exp = scheduleRequest.get("createdBy");

with this:

Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);

If it works, then you may try to add the Join logic into the Criteria Query. But right now I can't test it, so I prefer to see if somebody else wants to try.

Not a perfect answer though may be code snippets might help.

public <T> List<T> findListWhereInCondition(Class<T> clazz,
            String conditionColumnName, Serializable... conditionColumnValues) {
        QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
        addWhereInClause(queryBuilder, conditionColumnName,
                conditionColumnValues);
        queryBuilder.select();
        return queryBuilder.getResultList();

    }


private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
            String conditionColumnName, Serializable... conditionColumnValues) {

        Path<Object> path = queryBuilder.root.get(conditionColumnName);
        In<Object> in = queryBuilder.criteriaBuilder.in(path);
        for (Serializable conditionColumnValue : conditionColumnValues) {
            in.value(conditionColumnValue);
        }
        queryBuilder.criteriaQuery.where(in);

    }

You can check for yourself.

In this fiddle, I ran a test to demonstrate the blocking nature of await, as opposed to Promise.all which will start all of the promises and while one is waiting it will go on with the others.

In your .xml file within Button add this line--

android:textAllCaps="false"

The input shape you have defined is the shape of a single sample. The model itself expects some array of samples as input (even if its an array of length 1).

Your output really should be 4-d, with the 1st dimension to enumerate the samples. i.e. for a single image you should return a shape of (1, 32, 32, 3).

You can find more information here under "Convolution2D"/"Input shape"

Edit: Based on Danny's comment below, if you want a batch size of 1, you can add the missing dimension using this:

image = np.expand_dims(image, axis=0)

system "sleep 0.1";

does the trick.

I like using pandas.apply() with python format().

import pandas as pd
s = pd.Series([1.357, 1.489, 2.333333])

make_float = lambda x: "${:,.2f}".format(x)
s.apply(make_float)

Also, it can be easily used with multiple columns...

df = pd.concat([s, s * 2], axis=1)

make_floats = lambda row: "${:,.2f}, ${:,.3f}".format(row[0], row[1])
df.apply(make_floats, axis=1)

const tifOptions = [];

for (const [key, value] of Object.entries(tifs)) {
    tifOptions.push(<option value={key} key={key}>{value}</option>);
}

return (
   <select id="tif" name="tif" onChange={this.handleChange}>  
      { tifOptions }          
   </select>
)

Or, written in one line:

std::cout << std::distance(sampleArray.begin(),std::max_element(sampleArray.begin(), sampleArray.end()));

In addition to what eugene and stevenl posted, you might encounter problems with using both <> and <STDIN> in one script: <> iterates through (=concatenating) all files given as command line arguments.

However, should a user ever forget to specify a file on the command line, it will read from STDIN, and your code will wait forever on input

This works in Python 2.x.

For Python 3 look in the docs:

import urllib.request

with urllib.request.urlopen("http://www.python.org") as url:
    s = url.read()
    # I'm guessing this would output the html source code ?
    print(s)

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

A node is the generic name for any type of object in the DOM hierarchy. A node could be one of the built-in DOM elements such as document or document.body, it could be an HTML tag specified in the HTML such as <input> or <p> or it could be a text node that is created by the system to hold a block of text inside another element. So, in a nutshell, a node is any DOM object.

An element is one specific type of node as there are many other types of nodes (text nodes, comment nodes, document nodes, etc...).

The DOM consists of a hierarchy of nodes where each node can have a parent, a list of child nodes and a nextSibling and previousSibling. That structure forms a tree-like hierarchy. The document node has the html node as its child. The html node has its list of child nodes (the head node and the body node). The body node would have its list of child nodes (the top level elements in your HTML page) and so on.

So, a nodeList is simply an array-like list of nodes.

An element is a specific type of node, one that can be directly specified in the HTML with an HTML tag and can have properties like an id or a class. can have children, etc... There are other types of nodes such as comment nodes, text nodes, etc... with different characteristics. Each node has a property .nodeType which reports what type of node it is. You can see the various types of nodes here (diagram from MDN):

You can see an ELEMENT_NODE is one particular type of node where the nodeType property has a value of 1.

So document.getElementById("test") can only return one node and it's guaranteed to be an element (a specific type of node). Because of that it just returns the element rather than a list.

Since document.getElementsByClassName("para") can return more than one object, the designers chose to return a nodeList because that's the data type they created for a list of more than one node. Since these can only be elements (only elements typically have a class name), it's technically a nodeList that only has nodes of type element in it and the designers could have made a differently named collection that was an elementList, but they chose to use just one type of collection whether it had only elements in it or not.

EDIT: HTML5 defines an HTMLCollection which is a list of HTML Elements (not any node, only Elements). A number of properties or methods in HTML5 now return an HTMLCollection. While it is very similar in interface to a nodeList, a distinction is now made in that it only contains Elements, not any type of node.

The distinction between a nodeList and an HTMLCollection has little impact on how you use one (as far as I can tell), but the designers of HTML5 have now made that distinction.

For example, the element.children property returns a live HTMLCollection.

The other way to tackle it is to use this code snippet:

JSON.parse(JSON.stringify(response)).data

This feels so wrong but it works

I run a small experiment to verify that printing with DBL_DECIMAL_DIG does indeed exactly preserve the number's binary representation. It turned out that for the compilers and C libraries I tried, DBL_DECIMAL_DIG is indeed the number of digits required, and printing with even one digit less creates a significant problem.

#include <float.h>
#include <math.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

union {
    short s[4];
    double d;
} u;

void
test(int digits)
{
    int i, j;
    char buff[40];
    double d2;
    int n, num_equal, bin_equal;

    srand(17);
    n = num_equal = bin_equal = 0;
    for (i = 0; i < 1000000; i++) {
        for (j = 0; j < 4; j++)
            u.s[j] = (rand() << 8) ^ rand();
        if (isnan(u.d))
            continue;
        n++;
        sprintf(buff, "%.*g", digits, u.d);
        sscanf(buff, "%lg", &d2);
        if (u.d == d2)
            num_equal++;
        if (memcmp(&u.d, &d2, sizeof(double)) == 0)
            bin_equal++;
    }
    printf("Tested %d values with %d digits: %d found numericaly equal, %d found binary equal\n", n, digits, num_equal, bin_equal);
}

int
main()
{
    test(DBL_DECIMAL_DIG);
    test(DBL_DECIMAL_DIG - 1);
    return 0;
}

I run this with Microsoft's C compiler 19.00.24215.1 and gcc version 7.4.0 20170516 (Debian 6.3.0-18+deb9u1). Using one less decimal digit halves the number of numbers that compare exactly equal. (I also verified that rand() as used indeed produces about one million different numbers.) Here are the detailed results.

Microsoft C

Tested 999507 values with 17 digits: 999507 found numericaly equal, 999507 found binary equal
Tested 999507 values with 16 digits: 545389 found numericaly equal, 545389 found binary equal

Check if the session is empty or not in C# MVC Version Lower than 5.

I've been wrestling with this, and I know there are other options, but I've come to the conclusion the safest pattern is:

create table destination_old as select * from destination;

drop table destination;

create table destination as select
d.*, s.country
from destination_old d left join source s
on d.id=s.id;

It's safe because you have a copy of destination before you altered it. I suspect that update statements with joins weren't included in SQLite because they're powerful but a bit risky.

Using the pattern above you end up with two country fields. You can avoid that by explicitly stating all of the columns you want to retrieve from destination_old and perhaps using coalesce to retrieve the values from destination_old if the country field in source is null. So for example:

create table destination as select
d.field1, d.field2,...,coalesce(s.country,d.country) country
from destination_old d left join source s
on d.id=s.id;

I was able to get this work. I added the following to my custom CSS:

.wpcf7-form textarea{ 
    width: 100% !important;
    height:50px;
}

Inside the app/res/your_xml_layout_file.xml

1. Assign a name to your parent layout.
2. Go to your MainActivity and find your RelativeLayout by calling the findViewById(R.id."given_name").
3. Use the layout as a classic Object, by calling the method setBackgroundColor().

df.gdp = df.gdp.shift(-1) ## shift up
df.gdp.drop(df.gdp.shape[0] - 1,inplace = True) ## removing the last row

Assignment in javascript works from right to left. var var1 = var2 = var3 = 1;.

If the value of any of these variables is 1 after this statement, then logically it must have started from the right, otherwise the value or var1 and var2 would be undefined.

You can think of it as equivalent to var var1 = (var2 = (var3 = 1)); where the inner-most set of parenthesis is evaluated first.

import json

json_data = json.dumps({
  "result":[
    {
      "run":[
        {
          "action":"stop"
        },
        {
          "action":"start"
        },
        {
          "action":"start"
        }
      ],
      "find": "true"
    }
  ]
})

item_dict = json.loads(json_data)
print len(item_dict['result'][0]['run'])

Convert it in dict.

I generally like to use my own extension for that:

string data = "THExxQUICKxxBROWNxxFOX";
var dataspt = data.Split("xx");
//>THE  QUICK  BROWN  FOX 


//the extension class must be declared as static
public static class StringExtension
{   
    public static string[] Split(this string str, string splitter)
    {
        return str.Split(new[] { splitter }, StringSplitOptions.None);
    }
}

This will however lead to an Exception, if Microsoft decides to include this method-overload in later versions. It is also the likely reason why Microsoft has not included this method in the meantime: At least one company I worked for, used such an extension in all their C# projects.

It may also be possible to conditionally define the method at runtime if it doesn't exist.

If you don't want to install TortoiseSVN, you can simply install 'Subversion for Windows' from here:

http://sourceforge.net/projects/win32svn/

After installing, just open up a command prompt, go the folder you want to download into, then past in the checkout command as indicated on the project's 'source' page. E.g.

svn checkout http://projectname.googlecode.com/svn/trunk/ projectname-read-only

Note the space between the URL and the last string is intentional, the last string is the folder name into which the source will be downloaded.
