Regarding how you log messages within code, I would opt for the second approach:

ILog log = LogManager.GetLogger(typeof(Bar));
log.Info("message");

Where messages sent to the log above will be 'named' using the fully-qualifed type Bar, e.g.

MyNamespace.Foo.Bar [INFO] message

The advantage of this approach is that it is the de-facto standard for organising logging, it also allows you to filter your log messages by namespace. For example, you can specify that you want to log INFO level message, but raise the logging level for Bar specifically to DEBUG:

<log4net>
    <!-- appenders go here -->
    <root>
        <level value="INFO" />
        <appender-ref ref="myLogAppender" />
    </root>

    <logger name="MyNamespace.Foo.Bar">
        <level value="DEBUG" />
    </logger>
</log4net>

The ability to filter your logging via name is a powerful feature of log4net, if you simply log all your messages to "myLog", you loose much of this power!

Regarding the EPiServer CMS, you should be able to use the above approach to specify a different logging level for the CMS and your own code.

For further reading, here is a codeproject article I wrote on logging:

• The Art Of Logging

You usually see it in the ternary assignment operator;

Syntax

variable =  `condition ? result 1 : result 2;`

example:

boolean isNegative = number > 0 ? false : true;

which is "equivalent" in nature to the if else

if(number > 0){
    isNegative = false;
}
else{
    isNegative = true;
}

Other than examples given by different posters,

you can also use : to signify a label for a block which you can use in conjunction with continue and break..

for example:

public void someFunction(){
     //an infinite loop
     goBackHere: { //label
          for(int i = 0; i < 10 ;i++){
               if(i == 9 ) continue goBackHere;
          }
     }
}

TASKLIST doesn't set an exit code that you could check in a batch file. One workaround to checking the exit code could be parsing its standard output (which you are presently redirecting to NUL). Apparently, if the process is found, TASKLIST will display its details, which include the image name too. Therefore, you could just use FIND or FINDSTR to check if the TASKLIST's output contains the name you have specified in the request. Both FIND and FINDSTR set a non-null exit code if the search was unsuccessful. So, this would work:

@echo off
tasklist /fi "imagename eq notepad.exe" | find /i "notepad.exe" > nul
if not errorlevel 1 (taskkill /f /im "notepad.exe") else (
  specific commands to perform if the process was not found
)
exit

There's also an alternative that doesn't involve TASKLIST at all. Unlike TASKLIST, TASKKILL does set an exit code. In particular, if it couldn't terminate a process because it simply didn't exist, it would set the exit code of 128. You could check for that code to perform your specific actions that you might need to perform in case the specified process didn't exist:

@echo off
taskkill /f /im "notepad.exe" > nul
if errorlevel 128 (
  specific commands to perform if the process
  was not terminated because it was not found
)
exit

If you have root access to the server where mysql is running you should stop the mysql server using this command

sudo service mysql stop

Now start mysql using this command

sudo /usr/sbin/mysqld --skip-grant-tables  --skip-networking &

Now you can login to mysql using

sudo mysql
FLUSH PRIVILEGES;
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass');

Full instructions can be found here http://www.techmatterz.com/recover-mysql-root-password/

A portable solution could use getc.

#include <stdio.h>

char buffer[MAX_FILE_SIZE];
size_t i;

for (i = 0; i < MAX_FILE_SIZE; ++i)
{
    int c = getc(fp);

    if (c == EOF)
    {
        buffer[i] = 0x00;
        break;
    }

    buffer[i] = c;
}

If you don't want to have a MAX_FILE_SIZE macro or if it is a big number (such that buffer would be to big to fit on the stack), use dynamic allocation.

You need to escape ", so it won't be interpreted as end of string. Use \ to escape it:

echo "<script>$('#edit_errors').html('<h3><em><font color=\"red\">Please Correct Errors Before Proceeding</font></em></h3>')</script>";

Read more: strings and escape sequences

You can also try to reset visual studio setting

1. Open Visual Studio Command Prompt

2. Enter command Devenv /ResetSettings

It will remove already saved TFS account and ask for credentials

Another way to check if something is in the path is to execute some innocent executable that is not going to fail if it's there, and check the result. As an example, next code snippet checks if maven is in the path:

mvn --help > NUL 2> NUL 
if errorlevel 1 goto mvnNotInPath

So I try to run mvn --help, ignore the output (don't actually want to see the help if maven is there)( > NUL), and also don't display the error message if maven was not found (2> NUL).

//ICO , DI ,10 years back , this was they way:

public class  AuditDAOImpl implements Audit{

    //dependency
    AuditDAO auditDAO = null;
        //Control of the AuditDAO is with AuditDAOImpl because its creating the object
    public AuditDAOImpl () {
        this.auditDAO = new AuditDAO ();
    }
}

Now with Spring 3,4 or latest its like below

public class  AuditDAOImpl implements Audit{

    //dependency

     //Now control is shifted to Spring. Container find the object and provide it. 
    @Autowired
    AuditDAO auditDAO = null;

}

Overall the control is inverted from old concept of coupled code to the frameworks like Spring which makes the object available. So that's IOC as far as I know and Dependency injection as you know when we inject the dependent object into another object using Constructor or setters . Inject basically means passing it as an argument. In spring we have XML & annotation based configuration where we define bean object and pass the dependent object with Constructor or setter injection style.

For those who want a "standard" text formatting of the hash, you can use something like the following:

static string Hash(string input)
{
    using (SHA1Managed sha1 = new SHA1Managed())
    {
        var hash = sha1.ComputeHash(Encoding.UTF8.GetBytes(input));
        var sb = new StringBuilder(hash.Length * 2);

        foreach (byte b in hash)
        {
            // can be "x2" if you want lowercase
            sb.Append(b.ToString("X2"));
        }

        return sb.ToString();
    }
}

This will produce a hash like 0C2E99D0949684278C30B9369B82638E1CEAD415.

Or for a code golfed version:

static string Hash(string input)
{
    var hash = new SHA1Managed().ComputeHash(Encoding.UTF8.GetBytes(input));
    return string.Concat(hash.Select(b => b.ToString("x2")));
}

I developed a non-matlab software for direct compilation of m-files (TMC Compiler). This is an open-source converter of m-files projects to C. The compiler produces the C code that may be linked with provided open-source run-time library to produce a stand-alone application. The library implements a set of build-in functions; the linear-algebra operations use LAPACK code. It is possible to expand the set of the build-in functions by custom implementation as described in the documentation.

The first maximum you would hit is the length of a String which is 2³¹-1 digits. It's much smaller than the maximum of a BigInteger but IMHO it loses much of its value if it can't be printed.

Len(word)

Although that's not what your question title asks =)

You have to include sort function which is in algorithm header file which is a standard template library in c++.

Usage: std::sort(str.begin(), str.end());

#include <iostream>
#include <algorithm>  // this header is required for std::sort to work
int main()
{
    std::string s = "dacb";
    std::sort(s.begin(), s.end());
    std::cout << s << std::endl;

    return 0;
}

OUTPUT:

abcd

You can try to do json.loads(), which will throw a ValueError if the string you pass can't be decoded as JSON.

In general, the "Pythonic" philosophy for this kind of situation is called EAFP, for Easier to Ask for Forgiveness than Permission.

((EditText) findViewById(R.id.User)).setText("");
((EditText) findViewById(R.id.Password)).setText("");

This is my version (simple and easy):
uses memory only twice the size of original array.
[ a is the left array ] [ b is the right array ] [ c used to merge a and b ] [ p is counter for c ]

void MergeSort(int list[], int size)
{
    int blockSize = 1, p;
    int *a, *b;
    int *c = new int[size];
    do
    {
        for (int k = 0; k < size; k += (blockSize * 2))
        {
            a = &list[k];
            b = &list[k + blockSize];
            p = 0;
            for (int i = 0, j = 0; i < blockSize || j < blockSize;)
            {
                if ((j < blockSize) && ((k + j + blockSize) >= size))
                {
                    ++j;
                }
                else if ((i < blockSize) && ((k + i) >= size))
                {
                    ++i;
                }
                else if (i >= blockSize)
                {
                    c[p++] = b[j++];
                }
                else if (j >= blockSize)
                {
                    c[p++] = a[i++];
                }
                else if (a[i] >= b[j])
                {
                    c[p++] = b[j++];
                }
                else if (a[i] < b[j])
                {
                    c[p++] = a[i++];
                }
            }
            for (int i = 0; i < p; i++)
            {
                a[i] = c[i];
            }
        }
        blockSize *= 2;
    } while (blockSize < size);
}

For future seekers who might have dropped simple details like me, in my case I just have forgotten to call my action function with parentheses.

actions.js:

export function addNewComponent() {
  return {
    type: ADD_NEW_COMPONENT,
  };
}

myComponent.js:

import React, { useEffect } from 'react';
import { addNewComponent } from '../../redux/actions';

  useEffect(() => {
    dispatch(refreshAllComponents); // <= Here was what I've missed.
  }, []);

I've forgotten to dispatch the action function with (). So doing this solved my issue.

  useEffect(() => {
    dispatch(refreshAllComponents());
  }, []);

Again this might have nothing to do with OP's problem, but I hope I helps people with the same problem as mine.

You can use gnu objdump. objdump -p your.dll. Then pan to the .edata section contents and you'll find the exported functions under [Ordinal/Name Pointer] Table.

You can try this too:

public class Match
{
    [Key]
    public int MatchId { get; set; }

    [ForeignKey("HomeTeam"), Column(Order = 0)]
    public int? HomeTeamId { get; set; }
    [ForeignKey("GuestTeam"), Column(Order = 1)]
    public int? GuestTeamId { get; set; }

    public float HomePoints { get; set; }
    public float GuestPoints { get; set; }
    public DateTime Date { get; set; }

    public virtual Team HomeTeam { get; set; }
    public virtual Team GuestTeam { get; set; }
}

When you make a FK column allow NULLS, you are breaking the cycle. Or we are just cheating the EF schema generator.

In my case, this simple modification solve the problem.

EDIT 2020: Most of these are basically just to test resolution stuff, some of them even outdated, sadly, mobile browser development went sideways with desktop (especially in Apple), therefore one can't really "emulate" a real phone with these as mentioned with comment.

To emulate real phones, often the best choice is to download a desktop app which, for Windows, is usually paid/freemium, on Mac just use the Xcode one (but I doubt Mac people are looking for this Q/A).

Freemium online easy to use that I found recently is Appetize.io it seems to really render the screen according to network, but honestly I didn't really dig into whether it also has identical features and indentically missing features as real iOS.

Online simulators / emulators I use

1) recombu

Fine simulator which - unlike resizing browser window to mobile phone dimensions - acts same as a smart phone. Don't be confused that you can't edit address bar in safari - just open deveolper tools (usually F12) and rewrite iframe's source URL to yours.
Link: http://recombu.com/mobile/interactive/ios7-demo/

2) responsimulator

Seems to work like recombu, but you can open url directly by text input and you can zoom in/out.
Link: http://www.responsimulator.com/

3) transmog

This one seems to process the webpage, but it emulates old iPhone - still handy sometimes.
Link: http://transmog.net/iphone-simulator/mobile-web-browser-emulator.php

X) google it / internet search for it

Always use google (or other internet searchers) to check for other simulators/emulators and new versions.
Link with example google search for this one:
https://www.google.cz/search?q=online+iphone+emulator

Browser device mode

If you open your browser's developer's tools (in Chrome F12), there will probably be an option to toggle device mode (in Chrome it is the little smartphone icon at top-left).

After choosing this option GUI will change and will provide option to select device to simulate (in Chrome it is at the top - select option "Device"), after selecting device, refreshing the page is often adviced to ensure simulator's accuracy.

As of Python 3.6+, the best way of doing this is by the new timespec argument for isoformat.

isoformat(timespec='seconds', sep=' ')

Usage:

>>> datetime.now().isoformat(timespec='seconds')
'2020-10-16T18:38:21'
>>> datetime.now().isoformat(timespec='seconds', sep=' ')
'2020-10-16 18:38:35'

BluetoothAdapter.getDefaultAdapter().isEnabled -> returns true when bluetooth is open

val audioManager = this.getSystemService(Context.AUDIO_SERVICE) as AudioManager

audioManager.isBluetoothScoOn -> returns true when device connected

Though answer was really helpful but some how it missed some more extra detail. I hope below will help understand the shutdown process in java, in addition to the answer above:

1. In an orderly* shutdown, the JVM first starts all registered shutdown hooks. Shutdown hooks are unstarted threads that are registered with Runtime.addShutdownHook.
2. JVM makes no guarantees on the order in which shutdown hooks are started. If any application threads (daemon or nondaemon) are still running at shutdown time, they continue to run concurrently with the shutdown process.
3. When all shutdown hooks have completed, the JVM may choose to run finalizers if runFinalizersOnExit is true, and then halts.
4. JVM makes no attempt to stop or interrupt any application threads that are still running at shutdown time; they are abruptly terminated when the JVM eventually halts.
5. If the shutdown hooks or finalizers don’t complete, then the orderly shutdown process “hangs” and the JVM must be shut down abruptly.
6. In an abrupt shutdown, the JVM is not required to do anything other than halt the JVM; shutdown hooks will not run.

PS: The JVM can shut down in either an orderly or abrupt manner.

1. An orderly shutdown is initiated when the last “normal” (nondaemon) thread terminates, someone calls System.exit, or by other platform-specific means (such as sending a SIGINT or hitting Ctrl-C).
2. While above is the standard and preferred way for the JVM to shut down, it can also be shut down abruptly by calling Runtime.halt or by killing the JVM process through the operating system (such as sending a SIGKILL).

Swift 3:

  UITextField.appearance().tintColor = UIColor.black
  UITextView.appearance().tintColor = UIColor.black

Based on your comments, we need to go over how the Bundling mechanism works in MVC.

Edit: Based on the comment below by VSDev, you need to ensure WebGrease is installed into your project. NuGet would be the easiest was to install this package.

When you set a bundle configuration (Example not from above to illustrate)

bundles.Add(new ScriptBundle("~/bundles/mainJs")
      .Include("~/Scripts/mainSite.js")
      .Include("~/Scripts/helperStuff.js");

You then, in your views, call something like @Scripts.Render("~/bundles/mainJs"). When your web.config is set into a debug compilation OR you explicitly turn off bundling using the following line in your BundleConfig.cs file

BundleTable.EnableOptimizations = false;

Then, in your view, you will see the following rendered out

<script src="/Scripts/mainSite.js" type="text/javascript"></script>
<script src="/Scripts/helperStuff.js" type="text/javascript"></script>

These are the individual items that made up our bundle, uncompressed and listed individually. The reason these list out individually in debug mode is so that you can debug your scripts and see them as you wrote them (actual variable names, etc).

Now, when we are not in a debug compilation and have not turned off the EnableOptimizations feature, MVC will combine those files in our bundles, compress (minify) them and output only a single script tag.

<script src="/bundles/mainJs?v=someBigLongNumber" type="text/javascript"></script>

Notice that the source is the same as the name of the bundle from the bundle configurations. Also, the number after the ?v= will change anytime you change a file in that bundle. This is to help prevent caching of old js and css files by the client browsers.

Your scripts are still there and being outputted, but they are being compressed and combined into a single file called /bundles/mainJs. This feature is present to

A) compress the files and reduce information being transmitted and,

B) reduce the number of calls to a website to retrieve the necessary content to render the page.

Nothing is missing, it sounds like everything is working as intended. In a production site, the minification makes these files almost impossible to read, thus why the minification does not take affect while debugging.

As to why the jQuery UI is still being a single JS file, ensure someone didn't hard code that into your layout view. As for the JS errors, it could be errors that are present on your development box or perhaps something did not compress correctly (however, in all of my MVC development, I have not seen a JS error because of bad minification).

If a class doesn't have any constructor provided by programmer, then java compiler will add a default constructor with out parameters which will call super class constructor internally with super() call. This is called as default constructor.

In your case, there is no default constructor as you are adding them programmatically. If there are no constructors added by you, then compiler generated default constructor will look like this.

public Module()
{
   super();
}

Note: In side default constructor, it will add super() call also, to call super class constructor.

Purpose of adding default constructor:

Constructor's duty is to initialize instance variables, if there are no instance variables you could choose to remove constructor from your class. But when you are inheriting some class it is your class responsibility to call super class constructor to make sure that super class initializes all its instance variables properly.

That's why if there are no constructors, java compiler will add a default constructor and calls super class constructor.

Good guestion! -- where I have not yet found a satisfying answer for my case, the answer I provide here works for me, but may not be future proof...

If one uses gcc (clang?) and have -Werror and -Wbad-function-cast defined,

int val = (int)pow(10,9);

will result:

error: cast from function call of type 'double' to non-matching type 'int' [-Werror=bad-function-cast]

(for a good reason, overflow and where values are rounded needs to be thought out)

EDIT: 2020-08-30: So, my use case casting the value from function returning double to int, and chose pow() to represent that in place of a private function somewhere. Then I sidestepped thinking pow() more. (See comments more why pow() used below could be problematic...).

After properly thought out (that parameters to pow() are good), int val = pow(10,9); seems to work with gcc 9.2 x86-64 ...

but note:

printf("%d\n", pow(10,4));

may output e.g.

-1121380856

(did for me) where

int i = pow(10,4); printf("%d\n", i);

printed

10000

in one particular case I tried.

Here's an example:

#Create a data frame
> d<- data.frame(a=1:3, b=2:4)
> d
  a b
1 1 2
2 2 3
3 3 4

#currently, there are no levels in the `a` column, since it's numeric as you point out.
> levels(d$a)
NULL

#Convert that column to a factor
> d$a <- factor(d$a)
> d
  a b
1 1 2
2 2 3
3 3 4

#Now it has levels.
> levels(d$a)
[1] "1" "2" "3"

You can also handle this when reading in your data. See the colClasses and stringsAsFactors parameters in e.g. readCSV().

Note that, computationally, factoring such columns won't help you much, and may actually slow down your program (albeit negligibly). Using a factor will require that all values are mapped to IDs behind the scenes, so any print of your data.frame requires a lookup on those levels -- an extra step which takes time.

Factors are great when storing strings which you don't want to store repeatedly, but would rather reference by their ID. Consider storing a more friendly name in such columns to fully benefit from factors.

Sometimes we have an upstream that rebased/rewound a branch we're depending on. This can be a big problem -- causing messy conflicts for us if we're downstream.

The magic is git pull --rebase

A normal git pull is, loosely speaking, something like this (we'll use a remote called origin and a branch called foo in all these examples):

# assume current checked out branch is "foo"
git fetch origin
git merge origin/foo

At first glance, you might think that a git pull --rebase does just this:

git fetch origin
git rebase origin/foo

But that will not help if the upstream rebase involved any "squashing" (meaning that the patch-ids of the commits changed, not just their order).

Which means git pull --rebase has to do a little bit more than that. Here's an explanation of what it does and how.

Let's say your starting point is this:

a---b---c---d---e  (origin/foo) (also your local "foo")

Time passes, and you have made some commits on top of your own "foo":

a---b---c---d---e---p---q---r (foo)

Meanwhile, in a fit of anti-social rage, the upstream maintainer has not only rebased his "foo", he even used a squash or two. His commit chain now looks like this:

a---b+c---d+e---f  (origin/foo)

A git pull at this point would result in chaos. Even a git fetch; git rebase origin/foo would not cut it, because commits "b" and "c" on one side, and commit "b+c" on the other, would conflict. (And similarly with d, e, and d+e).

What git pull --rebase does, in this case, is:

git fetch origin
git rebase --onto origin/foo e foo

This gives you:

 a---b+c---d+e---f---p'---q'---r' (foo)

You may still get conflicts, but they will be genuine conflicts (between p/q/r and a/b+c/d+e/f), and not conflicts caused by b/c conflicting with b+c, etc.

Answer taken from (and slightly modified):
http://gitolite.com/git-pull--rebase

To rotate, you can use key frames and a transform.

div {
    margin: 20px;
    width: 100px; 
    height: 100px;    
    background: #f00;
    -webkit-animation-name: spin;
    -webkit-animation-duration: 40000ms;
    -webkit-animation-iteration-count: infinite;
    -webkit-animation-timing-function: linear;
    -moz-animation-name: spin;
    -moz-animation-duration: 40000ms;
    -moz-animation-iteration-count: infinite;
    -moz-animation-timing-function: linear;
    -ms-animation-name: spin;
    -ms-animation-duration: 40000ms;
    -ms-animation-iteration-count: infinite;
    -ms-animation-timing-function: linear;
}

@-webkit-keyframes spin {
  from {
    -webkit-transform:rotate(0deg);
  }

  to {
    -webkit-transform:rotate(360deg);
  }
}

You can load a Java class from source at runtime. (Using JCI, BeanShell or JavaCompiler)

This would allow you to change the Enum values as you wish.

Note: this wouldn't change any classes which referred to these enums so this might not be very useful in reality.

protected void UpdateButton_Click(object sender, EventArgs e)
        {
            var values = string.Format("Name={0}&Family={1}&Id={2}", NameToUpdateTextBox.Text, FamilyToUpdateTextBox.Text, IdToUpdateTextBox.Text);
            var bytes = Encoding.ASCII.GetBytes(values);
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(string.Format("http://localhost:51436/api/employees"));
            request.Method = "PUT";
            request.ContentType = "application/x-www-form-urlencoded";
            using (var requestStream = request.GetRequestStream())
            {
                requestStream.Write(bytes, 0, bytes.Length);
            }
            var response =  (HttpWebResponse) request.GetResponse();

            if (response.StatusCode == HttpStatusCode.OK)
                UpdateResponseLabel.Text = "Update completed";
            else
                UpdateResponseLabel.Text = "Error in update";
        }

                            lock.notify();
                            lock.wait();
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
                }
            }
        });
        Thread t2 = new Thread(new Runnable() {
            public void run() {

                for (int itr = 2; itr < 51; itr = itr + 2) {
                    synchronized (lock) {
                        System.out.print(" " + itr);
                        try {
                            lock.notify();
                            if(itr==50)
                                break;
                            lock.wait();
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
                }
            }
        });
        try {
            t1.start();
            t2.start();
            t1.join();
            t2.join();
            System.out.println("\nPrinting over");
        } catch (Exception e) {

        }
    }
}

In order to achieve so, the run methods of the two threads above have to be called one after the other, i.e. they need to be synchronized and I am achieving that using locks.

The code works like this: t1.run prints the odd number and notifies any waiting thread that it is going to release the lock, then goes into a wait state.

At this point t2.run is invoked, it prints the next even number, notifies other threads that it is about to release the lock it holds and then goes into wait state.

This continues till the itr in t2.run() reaches 50, at this point our goal has been achieved and we need to kill these two threads.

By breaking, I avoid calling lock.wait() in t2.run and t2 thread is thus shutdown, the control will now go to t1.run since it was waiting to acquire the lock; but here itr value will be > 51 and we will come out of its run(), thus shutting down the thread.

If break is not used in t2.run(), though we will see numbers 1 to 50 on the screen but the two threads will get into a deadlock situation and continue to be in wait state.

Please note instead of

public TomcatEmbeddedServletContainerFactory tomcatFactory()

I had to use the following method signature

public EmbeddedServletContainerFactory embeddedServletContainerFactory() 

This is the solution I came up with:

import time
from threading import Thread
from threading import Lock

def myfunc(i, mutex):
    mutex.acquire(1)
    time.sleep(1)
    print "Thread: %d" %i
    mutex.release()


mutex = Lock()
for i in range(0,10):
    t = Thread(target=myfunc, args=(i,mutex))
    t.start()
    print "main loop %d" %i

Output:

main loop 0
main loop 1
main loop 2
main loop 3
main loop 4
main loop 5
main loop 6
main loop 7
main loop 8
main loop 9

I believe you have to set the property relaxedUrlToFileSystemMapping in your web.config. Haack wrote an article about this a little while ago (and there are some other SO posts asking the same types of question)

<system.web>
<httpRuntime relaxedUrlToFileSystemMapping="true" />

Edit From the comments below, later versions of .NET / IIS may require this to be in the system.WebServer element.

<system.webServer>
<httpRuntime relaxedUrlToFileSystemMapping="true" />

Make sure they are both using the same interpreter. This happened to me on Ubuntu:

$ ipython3 -c 'import sys; print(sys.version)'
3.4.2 (default, Jun 19 2015, 11:34:49) \n[GCC 4.9.1]

$ python3 -c 'import sys; print(sys.version)'
3.3.0 (default, Nov 27 2012, 12:11:06) \n[GCC 4.6.3]

And sys.path was different between the two interpreters. To fix it, I removed Python 3.3.

Here is a great article explaining ByteBuffer benefits. Following are the key points in the article:

• First advantage of a ByteBuffer irrespective of whether it is direct or indirect is efficient random access of structured binary data (e.g., low-level IO as stated in one of the answers). Prior to Java 1.4, to read such data one could use a DataInputStream, but without random access.

Following are benefits specifically for direct ByteBuffer/MappedByteBuffer. Note that direct buffers are created outside of heap:

1. Unaffected by gc cycles: Direct buffers won't be moved during garbage collection cycles as they reside outside of heap. TerraCota's BigMemory caching technology seems to rely heavily on this advantage. If they were on heap, it would slow down gc pause times.

2. Performance boost: In stream IO, read calls would entail system calls, which require a context-switch between user to kernel mode and vice versa, which would be costly especially if file is being accessed constantly. However, with memory-mapping this context-switching is reduced as data is more likely to be found in memory (MappedByteBuffer). If data is available in memory, it is accessed directly without invoking OS, i.e., no context-switching.

Note that MappedByteBuffers are very useful especially if the files are big and few groups of blocks are accessed more frequently.

3. Page sharing: Memory mapped files can be shared between processes as they are allocated in process's virtual memory space and can be shared across processes.

In case someone needs "financial rounding" (0.5 rounds always up):

def myround(x, base=5):
    roundcontext = decimal.Context(rounding=decimal.ROUND_HALF_UP)
    decimal.setcontext(roundcontext)
    return int(base *float(decimal.Decimal(x/base).quantize(decimal.Decimal('0'))))

As per documentation other rounding options are:

ROUND_CEILING (towards Infinity),
ROUND_DOWN (towards zero),
ROUND_FLOOR (towards -Infinity),
ROUND_HALF_DOWN (to nearest with ties going towards zero),
ROUND_HALF_EVEN (to nearest with ties going to nearest even integer),
ROUND_HALF_UP (to nearest with ties going away from zero), or
ROUND_UP (away from zero).
ROUND_05UP (away from zero if last digit after rounding towards zero would have been 0 or 5; otherwise towards zero)

By default Python uses ROUND_HALF_EVEN as it has some statistical advantages (the rounded results are not biased).

If the order of the execution is not important and you need both some javascript AND some codebehind to be fired on an asp element, heres what you can do.

What you can take away from my example: I have a div covering the ASP control that I want both javascript and codebehind to be ran from. The div's onClick method AND the calendar's OnSelectionChanged event both get fired this way.

In this example, i am using an ASP Calendar control, and im controlling it from both javascript and codebehind:

Front end code:

        <div onclick="showHideModal();">
            <asp:Calendar 
                OnSelectionChanged="DatepickerDateChange" ID="DatepickerCalendar" runat="server" 
                BorderWidth="1px" DayNameFormat="Shortest" Font-Names="Verdana" 
                Font-Size="8pt" ShowGridLines="true" BackColor="#B8C9E1" BorderColor="#003E51" Width="100%"> 
                <OtherMonthDayStyle ForeColor="#6C5D34"> </OtherMonthDayStyle> 
                <DayHeaderStyle  ForeColor="black" BackColor="#D19000"> </DayHeaderStyle>
                <TitleStyle BackColor="#B8C9E1" ForeColor="Black"> </TitleStyle> 
                <DayStyle BackColor="White"> </DayStyle> 
                <SelectedDayStyle BackColor="#003E51" Font-Bold="True"> </SelectedDayStyle> 
            </asp:Calendar>
        </div>

Codebehind:

        protected void DatepickerDateChange(object sender, EventArgs e)
        {
            if (toFromPicked.Value == "MainContent_fromDate")
            {
                fromDate.Text = DatepickerCalendar.SelectedDate.ToShortDateString();
            }
            else
            {
                toDate.Text = DatepickerCalendar.SelectedDate.ToShortDateString();
            }
        }

Opening a file in "write" mode clears it, you don't specifically have to write to it:

open("filename", "w").close()

(you should close it as the timing of when the file gets closed automatically may be implementation specific)

For anyone using Sequelize version 3 and above, use:

Is it possible to do it this way, as opposed to using something like Raphael or jQuery SVG?

Definitely.

If it is possible, what's the technique?

This annotated code snippet works:

<!DOCTYPE html>
<html>
    <head>
        <title>SVG Illustrator Test</title> 
    </head>
    <body>

        <object data="alpha.svg" type="image/svg+xml"
         id="alphasvg" width="100%" height="100%"></object>

        <script>
            var a = document.getElementById("alphasvg");

            // It's important to add an load event listener to the object,
            // as it will load the svg doc asynchronously
            a.addEventListener("load",function(){

                // get the inner DOM of alpha.svg
                var svgDoc = a.contentDocument;
                // get the inner element by id
                var delta = svgDoc.getElementById("delta");
                // add behaviour
                delta.addEventListener("mousedown",function(){
                        alert('hello world!')
                }, false);
            }, false);
        </script>
    </body>
</html>

Note that a limitation of this technique is that it is restricted by the same-origin policy, so alpha.svg must be hosted on the same domain as the .html file, otherwise the inner DOM of the object will be inaccessible.

Important thing to run this HTML, you need host HTML file to web server like IIS, Tomcat

I know it has been quite sometime that you asked this but, if someone else needs, I did what was saying here " How to upload a project to Github " and after the top answer of this question right here. And after was the top answer was saying here "git error: failed to push some refs to" I don't know what exactly made everything work. But now is working.

Other users commenting that the Content-Type is plain/text when encoding. You have to set the Content-Type first w.Header().Set, then the HTTP response code w.WriteHeader.

If you call w.WriteHeader first then call w.Header().Set after you will get plain/text.

An example handler might look like this;

func SomeHandler(w http.ResponseWriter, r *http.Request) {
    data := SomeStruct{}
    w.Header().Set("Content-Type", "application/json")
    w.WriteHeader(http.StatusCreated)
    json.NewEncoder(w).Encode(data)
}

Using the "point" leads to the creation of a folder named "point" (on Ubuntu 16).

tar -tf site1.bz2 -C /var/www/site1/ .

I dealt with this in more detail and prepared an example. Multi-line recording, plus an exception.

tar -tf site1.bz2\
    -C /var/www/site1/ style.css\
    -C /var/www/site1/ index.html\
    -C /var/www/site1/ page2.html\
    -C /var/www/site1/ page3.html\
    --exclude=images/*.zip\
    -C /var/www/site1/ images/
    -C /var/www/site1/ subdir/
/

I hit this issue working with Server Sent Events. The problem was solved when I noticed that the domain name I used to initiate the connection included a trailing slash, e.g. https://foo.bar.bam/ failed with ERR_HTTP_PROTOCOL_ERROR while https://foo.bar.bam worked.

Another way you can do it, is using addClassRules. It's specific for classes, while the option using selector and .rules is more a generic way.

Before calling

$(form).validate()

Use like this:

jQuery.validator.addClassRules('myClassName', {
        required: true /*,
        other rules */
    });

Ref: http://docs.jquery.com/Plugins/Validation/Validator/addClassRules#namerules

I prefer this syntax for a case like this.

function in_arrayi($needle, $haystack) {
    return in_array(strtolower($needle), array_map('strtolower', $haystack));
}

Source: php.net in_array manual page.

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

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

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

import string

word = input('Please select a word to test \n')
word = word.lower()
num = len(word)

x = round((len(word)-1)/2)
#defines first half of string
first = word[:x]

#reverse second half of string
def reverse_odd(text):
    lst = []
    count = 1
    for i in range(x+1, len(text)):

        lst.append(text[len(text)-count])
        count += 1
    lst = ''.join(lst)
    return lst

#reverse second half of string
def reverse_even(text):
    lst = []
    count = 1
    for i in range(x, len(text)):
        lst.append(text[len(text)-count])
        count += 1
    lst = ''.join(lst)
    return lst


if reverse_odd(word) == first or reverse_even(word) == first:
    print(string.capwords(word), 'is a palindrome')
else:
    print(string.capwords(word), 'is not a palindrome')

As said in previous answers the 'normal' way is to add it to a JScrollPane, but sometimes you don't want it to scroll (don't ask me when:)). Then you can add the TableHeader yourself. Like this:

JPanel tablePanel = new JPanel(new BorderLayout());
JTable table = new JTable();
tablePanel.add(table, BorderLayout.CENTER);
tablePanel.add(table.getTableHeader(), BorderLayout.NORTH);

$query = DB::table('dms_stakeholder_permissions');
$query->select(DB::raw('group_concat(dms_stakeholder_permissions.fid) as fid'),'dms_stakeholder_permissions.rights');
$query->where('dms_stakeholder_permissions.stakeholder_id','4');
$query->orWhere(function($subquery)  use ($stakeholderId){
            $subquery->where('dms_stakeholder_permissions.stakeholder_id',$stakeholderId);
            $subquery->whereIn('dms_stakeholder_permissions.rights',array('1','2','3'));
    });

 $result = $query->get();

return $result;

// OUTPUT @input $stakeholderId = 1

//select group_concat(dms_stakeholder_permissions.fid) as fid, dms_stakeholder_permissionss.rights from dms_stakeholder_permissions where dms_stakeholder_permissions.stakeholder_id = 4 or (dms_stakeholder_permissions.stakeholder_id = 1 and dms_stakeholder_permissions.rights in (1, 2, 3))

I don't think there would be any significant performance difference between them, but I would prefer the 1st way.

If you have a Boolean reference, Boolean.toString(boolean) will throw NullPointerException if your reference is null. As the reference is unboxed to boolean before being passed to the method.

While, String.valueOf() method as the source code shows, does the explicit null check:

public static String valueOf(Object obj) {
    return (obj == null) ? "null" : obj.toString();
}

Just test this code:

Boolean b = null;

System.out.println(String.valueOf(b));    // Prints null
System.out.println(Boolean.toString(b));  // Throws NPE

For primitive boolean, there is no difference.

When I ran into this issue of wanting a less generic DropdownStringButton, I just created it:

dropdown_string_button.dart

import 'package:flutter/material.dart';
// Subclass of DropdownButton based on String only values.
// Yes, I know Flutter discourages subclassing, but this seems to be
// a reasonable exception where a commonly used specialization can be
// made more easily usable.
//
// Usage: 
// DropdownStringButton(items: ['A', 'B', 'C'], value: 'A', onChanged: (string) {})
//
class DropdownStringButton extends DropdownButton<String> {
  DropdownStringButton({
    Key key, @required List<String> items, value, hint, disabledHint,
    @required onChanged, elevation = 8, style, iconSize = 24.0, isDense = false,
    isExpanded = false, }) : 
    assert(items == null || value == null || items.where((String item) => item == value).length == 1),
        super(
          key: key,
          items: items.map((String item) {
            return DropdownMenuItem<String>(child: Text(item), value: item);
          }).toList(),
        value: value, hint: hint, disabledHint: disabledHint, onChanged: onChanged,
        elevation: elevation, style: style, iconSize: iconSize, isDense: isDense,
        isExpanded: isExpanded,
        );
    }

#include <iostream>
#include <ctime>
#include <cstdlib> //_sleep()  --- just a function that waits a certain amount of milliseconds

using namespace std;

int main()
{

    clock_t cl;     //initializing a clock type

    cl = clock();   //starting time of clock

    _sleep(5167);   //insert code here

    cl = clock() - cl;  //end point of clock

    _sleep(1000);   //testing to see if it actually stops at the end point

    cout << cl/(double)CLOCKS_PER_SEC << endl;  //prints the determined ticks per second (seconds passed)


    return 0;
}

//outputs "5.17"

You can put it in "(void)var;" expression (does nothing) so that a compiler sees it is used. This is portable between compilers.

E.g.

void foo(int param1, int param2)
{
    (void)param2;
    bar(param1);
}

Or,

#define UNUSED(expr) do { (void)(expr); } while (0)
...

void foo(int param1, int param2)
{
    UNUSED(param2);
    bar(param1);
}

This is a barebones look at what I've done to float one image over another.

I posted the technique I use to deal with these here

As an addition to Frank Heiken's answer, if you wish to use INSERT statements instead of copy from stdin, then you should specify the --inserts flag

pg_dump --host localhost --port 5432 --username postgres --format plain --verbose --file "<abstract_file_path>" --table public.tablename --inserts dbname

Notice that I left out the --ignore-version flag, because it is deprecated.

Did you forget to add the init.py in your package?

It will also work if you call intern() on the string before inserting it into the array. Interned strings are reference-equal (==) if and only if they are value-equal (equals().)

public static void main (String... aArguments) throws IOException {

String usuario = "Jorman";
String password = "14988611";

String strDatos="Jorman 14988611";
StringTokenizer tokens=new StringTokenizer(strDatos, " ");
int nDatos=tokens.countTokens();
String[] datos=new String[nDatos];
int i=0;

while(tokens.hasMoreTokens()) {
    String str=tokens.nextToken();
    datos[i]= str.intern();            
    i++;
}

//System.out.println (usuario);

if(datos[0]==usuario) {  
     System.out.println ("WORKING");    
}

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells;
for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
    dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
    dataGridView1.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.NotSet;
}

For a select like this

<select class="btn btn-info pull-right" id="list-name" style="width: auto;">
   <option id="0">CHOOSE AN OPTION</option>
   <option id="127">John Doe</option>
   <option id="129" selected>Jane Doe</option>

... you can get the id this way:

$('#list-name option:selected').attr('id');

Or you can use value instead, and get it the easy way...

<select class="btn btn-info pull-right" id="list-name" style="width: auto;">
   <option value="0">CHOOSE AN OPTION</option>
   <option value="127">John Doe</option>
   <option value="129" selected>Jane Doe</option>

like this:

$('#list-name').val();

To get the separator vertically centered relative to the menu text,

.menustyle li + li:before {
  content: ' | ';
  padding: 0;
  position: relative;
  top: -2px;
}

A good information: you don't need to check whether the Bundle object is null into the onCreate() method. Use the onRestoreInstanceState() method, which the system calls after the onStart() method. The system calls onRestoreInstanceState() only if there is a saved state to restore, so you do not need to check whether the Bundle is null

There is a much simpler solution for that.
Actually treating the items of JArray as JObject works.
Here is an example:
Let's say we have such array of JSON objects:

JArray jArray = JArray.Parse(@"[
              {
                ""name"": ""Croke Park II"",
                ""url"": ""http://twitter.com/search?q=%22Croke+Park+II%22"",
                ""promoted_content"": null,
                ""query"": ""%22Croke+Park+II%22"",
                ""events"": null
              },
              {
                ""name"": ""Siptu"",
                ""url"": ""http://twitter.com/search?q=Siptu"",
                ""promoted_content"": null,
                ""query"": ""Siptu"",
                ""events"": null
              }]");

To get access each item we just do the following:

foreach (JObject item in jArray)
{
    string name = item.GetValue("name").ToString();
    string url = item.GetValue("url").ToString();
    // ...
}

I was trying to do this with stacked plot bars. The code that worked for me was.

# Code to plot. Notice the variable ax.
ax = df.groupby('target').count().T.plot.bar(stacked=True, figsize=(10, 6))
ax.legend(bbox_to_anchor=(1.1, 1.05))

# Loop to add on each bar a tag in position
for rect in ax.patches:
    height = rect.get_height()

It happen if there are two more ContextLoaderListener exist in your project.

For ex: in my case 2 ContextLoaderListener was exist using

1. java configuration
2. web.xml

So, remove any one ContextLoaderListener from your project and run your application.

void ExplodeString( const std::string& string, const char separator, std::list<int>& result ) {
    if( string.size() ) {
        std::string::const_iterator last = string.begin();
        for( std::string::const_iterator i=string.begin(); i!=string.end(); ++i ) {
            if( *i == separator ) {
                const std::string str(last,i);
                int id = atoi(str.c_str());
                result.push_back(id);
                last = i;
                ++ last;
            }
        }
        if( last != string.end() ) result.push_back( atoi(&*last) );
    }
}

As is defined in RFC 1341:

In the Extended BNF notation of RFC 822, a Content-Type header field value is defined as follows:

Content-Type := type "/" subtype *[";" parameter]

type := "application" / "audio" / "image" / "message" / "multipart" / "text" / "video" / x-token

x-token := < The two characters "X-" followed, with no intervening white space, by any token >

subtype := token

parameter := attribute "=" value

attribute := token

value := token / quoted-string

token := 1*

tspecials := "(" / ")" / "<" / ">" / "@" ; Must be in / "," / ";" / ":" / "\" / <"> ; quoted-string, / "/" / "[" / "]" / "?" / "." ; to use within / "=" ; parameter values

And a list of known MIME types that can follow it (or, as Joe remarks, the IANA source).

As you can see the list is way too big for you to validate against all of them. What you can do is validate against the general format and the type attribute to make sure that is correct (the set of options is small) and just assume that what follows it is correct (and of course catch any exceptions you might encounter when you put it to actual use).

Also note the comment above:

If another primary type is to be used for any reason, it must be given a name starting with "X-" to indicate its non-standard status and to avoid any potential conflict with a future official name.

You'll notice that a lot of HTTP requests/responses include an X- header of some sort which are self defined, keep this in mind when validating the types.

It is likely that you are running the python executable from /usr/bin (Apple version) instead of /usr/loca/bin (Brew version)

You can either

a) check your PATH variable

or

b) run brew doctor

or

c) run which python

to check if it is the case.

Editor's note: Doing what this answer says is DANGEROUS! The LocalSystem account is a ...

Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

Changing the Identity from ApplicationPoolIdentity to LocalSystem did the work ;).

I am using win7 64 with IIS 7.5

You should logged in not as "root" user.

Or assign permission to your "current_user" to do this by using following command

sudo chown -R username.www-data /var/www

sudo chmod -R +rwx /var/www

Click Insert ->Object->Create from file ->Browse.

Once the file is selected choose the "Change icon" option and you will be able to rename the file and change the icon if you wish.

Hope this helps!

At first glance it doesn't look like you are doing anything wrong but you don't show all your code. The following worked for me when I was first checking out S3 and Node:

var AWS = require('aws-sdk');

if (typeof process.env.API_KEY == 'undefined') {
    var config = require('./config.json');
    for (var key in config) {
        if (config.hasOwnProperty(key)) process.env[key] = config[key];
    }
}

var s3 = new AWS.S3({accessKeyId: process.env.AWS_ID, secretAccessKey:process.env.AWS_KEY});
var objectPath = process.env.AWS_S3_FOLDER +'/test.xml';
s3.putObject({
    Bucket: process.env.AWS_S3_BUCKET, 
    Key: objectPath,
    Body: "<rss><data>hello Fred</data></rss>",
    ACL:'public-read'
}, function(err, data){
    if (err) console.log(err, err.stack); // an error occurred
    else {
        console.log(data);           // successful response
        s3.getObject({
            Bucket: process.env.AWS_S3_BUCKET, 
            Key: objectPath
        }, function(err, data){
            console.log(data.Body.toString());
        });
    }
});

YES

Through macros

3 Parameters:

#define my_func2(...) my_func3(__VA_ARGS__, 0.5)
#define my_func1(...) my_func2(__VA_ARGS__, 10)
#define VAR_FUNC(_1, _2, _3, NAME, ...) NAME
#define my_func(...) VAR_FUNC(__VA_ARGS__, my_func3, my_func2, my_func1)(__VA_ARGS__)

void my_func3(char a, int b, float c) // b=10, c=0.5
{
    printf("a=%c; b=%d; c=%f\n", a, b, c);
}

If you want 4th argument, then an extra my_func3 needs to be added. Notice the changes in VAR_FUNC, my_func2 and my_func

4 Parameters:

#define my_func3(...) my_func4(__VA_ARGS__, "default") // <== New function added
#define my_func2(...) my_func3(__VA_ARGS__, (float)1/2)
#define my_func1(...) my_func2(__VA_ARGS__, 10)
#define VAR_FUNC(_1, _2, _3, _4, NAME, ...) NAME
#define my_func(...) VAR_FUNC(__VA_ARGS__, my_func4, my_func3, my_func2, my_func1)(__VA_ARGS__)

void my_func4(char a, int b, float c, const char* d) // b=10, c=0.5, d="default"
{
    printf("a=%c; b=%d; c=%f; d=%s\n", a, b, c, d);
}

Only exception that float variables cannot be given default values (unless if it is the last argument as in the 3 parameters case), because they need period ('.'), which is not accepted within macro arguments. But can figure out a work around as seen in my_func2 macro (of 4 parameters case)

Program

int main(void)
{
    my_func('a');
    my_func('b', 20);
    my_func('c', 200, 10.5);
    my_func('d', 2000, 100.5, "hello");

    return 0;
}

Output:

a=a; b=10; c=0.500000; d=default                                                                                                                                                  
a=b; b=20; c=0.500000; d=default                                                                                                                                                  
a=c; b=200; c=10.500000; d=default                                                                                                                                                
a=d; b=2000; c=100.500000; d=hello  

In addition to using jQuery methods, you can use the native cells collection that the <tr> gives you.

$(t)[0].cells[1].innerHTML

Assuming t is a DOM element, you could bypass the jQuery object creation.

t.cells[1].innerHTML

In Notepad++ :

<option value value='1' >A
<option value value='2' >B
<option value value='3' >C
<option value value='4' >D


Find what: (.*)(>)(.)
Replace with: \3

In JavaScript 1.8.5, Object.getOwnPropertyNames returns an array of all properties found directly upon a given object.

Object.getOwnPropertyNames ( obj )

and another method Object.keys, which returns an array containing the names of all of the given object's own enumerable properties.

Object.keys( obj )

I used forEach to list values and keys in obj, same as for (var key in obj) ..

Object.keys(obj).forEach(function (key) {
      console.log( key , obj[key] );
});

This all are new features in ECMAScript , the mothods getOwnPropertyNames, keys won't supports old browser's.

IMHO this answer here solve issue in the most elegant way..

Developer should create a style,

<style name="noAnimTheme" parent="android:Theme">
  <item name="android:windowAnimationStyle">@null</item>
</style>

then in manifest set it as theme for activity or whole application.

<activity android:name=".ui.ArticlesActivity" android:theme="@style/noAnimTheme">
</activity>

Voila! Nice and easy..

Here's a simple hash function that I use for a hash table I built. Its basically for taking a text file and stores every word in an index which represents the alphabetical order.

int generatehashkey(const char *name)
{
        int x = tolower(name[0])- 97;
        if (x < 0 || x > 25)
           x = 26;
        return x;
}

What this basically does is words are hashed according to their first letter. So, word starting with 'a' would get a hash key of 0, 'b' would get 1 and so on and 'z' would be 25. Numbers and symbols would have a hash key of 26. THere is an advantage this provides; You can calculate easily and quickly where a given word would be indexed in the hash table since its all in an alphabetical order, something like this: Code can be found here: https://github.com/abhijitcpatil/general

Giving the following text as input: Atticus said to Jem one day, “I’d rather you shot at tin cans in the backyard, but I know you’ll go after birds. Shoot all the blue jays you want, if you can hit ‘em, but remember it’s a sin to kill a mockingbird.” That was the only time I ever heard Atticus say it was a sin to do something, and I asked Miss Maudie about it. “Your father’s right,” she said. “Mockingbirds don’t do one thing except make music for us to enjoy. They don’t eat up people’s gardens, don’t nest in corn cribs, they don’t do one thing but sing their hearts out for us. That’s why it’s a sin to kill a mockingbird.

This would be the output:

I googled a few similar questions and did not see any answers with my problem and its quite simple/easy solution.

Google Cloud Storage - a slightly different approach to images in READMEs

Here goes: like the OP, I wanted an image in my Github README, and, knowing the Markdown syntax for doing so, typed it in:

![My Image](https://storage.cloud.google.com/${MY_BUCKET}/${MY_IMAGE}

You need to complete the actual substitutions above (e.g. MY_IMAGE=image.jpg) for this to work.

But, wait...failure--there's no actual rendered photo! And the link is exactly as given by Google Storage!

Github camo - Anonymous Images

Github hosts your images anonymously, yay! However, this presents an issue for Google storage assets. You need to get the generated url from your Google Cloud Console.

I'm sure there's a smoother way, however, simply visit your given URL endpoint and copy the long URL. Details:

Instructions

1. Visit your storage console: https://console.cloud.google.com/storage/browser/${MY_BUCKET}?project=${MY_PROJECT}
2. Click on the image you'd like to display in Github (this brings up the "Object Details" page)
3. Copy pasta that URL (the one starting with https not gs) into a new browser tab/window
4. Copy pasta the new generated URL -- it should be longer -- from your new browser tab/window into your Github README file

Hopefully this helps speed up and clarify this issue for anyone else.

How I update my deviceToken

First when I login I send the first device token under the user collection and the current logged in user.

After that, I just override onNewToken(token:String) in my FirebaseMessagingService() and just update that value if a new token is generated for that user

class MyFirebaseMessagingService: FirebaseMessagingService() {
    override fun onMessageReceived(p0: RemoteMessage) {
        super.onMessageReceived(p0)
    }

    override fun onNewToken(token: String) {
    super.onNewToken(token)
    val currentUser= FirebaseAuth.getInstance().currentUser?.uid
    if(currentUser != null){
        FirebaseFirestore.getInstance().collection("user").document(currentUser).update("deviceToken",token)
    }
 }
} 

Each time your app opens it will check for a new token, if the user is not yet signed in it will not update the token, if the user is already logged in you can check for a newToken

Install the missing module separately using pip installer

pip3 install djangorestframework-jsonapi

This worked for me.

Or use a fancy list comprehension, which are supposed to be "computationally more efficient", when working with very very large files/lists

fd = open(filename,'r')
chars = [c for line in fd for c in line if c is not " "]
fd.close()

Btw: The answer that was accepted does not account for the whitespaces...

1- Explanation of Scripts

A)Syntax for inserting data in table is as below

Insert into table(col1,col2,col3,col4,col5)    

             -- To achieve this part i    
             --have used below variable
                ------@CSV_COLUMN-------

values(Col1 data in quote, Col2..quote,..Col5..quote)

-- To achieve this part 
-- i.e column data in 
--quote i have used 
--below variable
----@QUOTED_DATA---

C)To get above data from existing table we have to write the select query in such way that the output will be in form of as above scripts

D)Then Finally i have Concatenated above variable to create final script that's will generate insert script on execution

E)

@TEXT='SELECT ''INSERT INTO
 '+@TABLE_NAME+'('+@CSV_COLUMN+')VALUES('''+'+'+SUBSTRING(@QUOTED_DATA,1,LEN(@QUOTED_DATA)-5)+'+'+''')'''+' Insert_Scripts FROM '+@TABLE_NAME + @FILTER_CONDITION

F)And Finally Executed the above query EXECUTE(TEXT)

G)QUOTENAME() function is used to wrap column data inside quote

H)ISNULL is used because if any row has NULL data for any column the query fails and return NULL thats why to avoid that i have used ISNULL

I)And created the sp sp_generate_insertscripts for same

1- Just put the table name for which you want insert script

2- Filter condition if you want specific results

----------Final Procedure To generate Script------

CREATE PROCEDURE sp_generate_insertscripts
(
    @TABLE_NAME VARCHAR(MAX),
    @FILTER_CONDITION VARCHAR(MAX)=''
)
AS
BEGIN

SET NOCOUNT ON

DECLARE @CSV_COLUMN VARCHAR(MAX),
        @QUOTED_DATA VARCHAR(MAX),
        @TEXT VARCHAR(MAX)

SELECT @CSV_COLUMN=STUFF
(
    (
     SELECT ',['+ NAME +']' FROM sys.all_columns 
     WHERE OBJECT_ID=OBJECT_ID(@TABLE_NAME) AND 
     is_identity!=1 FOR XML PATH('')
    ),1,1,''
)

SELECT @QUOTED_DATA=STUFF
(
    (
     SELECT ' ISNULL(QUOTENAME('+NAME+','+QUOTENAME('''','''''')+'),'+'''NULL'''+')+'','''+'+' FROM sys.all_columns 
     WHERE OBJECT_ID=OBJECT_ID(@TABLE_NAME) AND 
     is_identity!=1 FOR XML PATH('')
    ),1,1,''
)

SELECT @TEXT='SELECT ''INSERT INTO '+@TABLE_NAME+'('+@CSV_COLUMN+')VALUES('''+'+'+SUBSTRING(@QUOTED_DATA,1,LEN(@QUOTED_DATA)-5)+'+'+''')'''+' Insert_Scripts FROM '+@TABLE_NAME + @FILTER_CONDITION

--SELECT @CSV_COLUMN AS CSV_COLUMN,@QUOTED_DATA AS QUOTED_DATA,@TEXT TEXT

EXECUTE (@TEXT)

SET NOCOUNT OFF

END

Just to clarify, be aware bracket placement is important!

These can be added to any HTML tags... span, div, table, p, tr, td etc.

AngularJS

ng-if="check1 && !check2" -- AND NOT
ng-if="check1 || check2" -- OR
ng-if="(check1 || check2) && check3" -- AND/OR - Make sure to use brackets

Angular2+

*ngIf="check1 && !check2" -- AND NOT
*ngIf="check1 || check2" -- OR
*ngIf="(check1 || check2) && check3" -- AND/OR - Make sure to use brackets

It's best practice not to do calculations directly within ngIfs, so assign the variables within your component, and do any logic there.

boolean check1 = Your conditional check here...
...

    // for numbers
    a = [1,3,2,4,5,6,7,8, 1,1,4,5,6]
    $.unique(a)
    [7, 6, 1, 8, 3, 2, 5, 4]

    // for string
    a = ["a", "a", "b"]
    $.unique(a)
    ["b", "a"]

And for dom elements there is no example is needed here I guess because you already know that!

Here is the jsfiddle link of live example: http://jsfiddle.net/3BtMc/4/

 var map = new google.maps.Map(document.getElementById("map"),{
                mapTypeId: google.maps.MapTypeId.ROADMAP

            });
var bounds = new google.maps.LatLngBounds();

for (i = 0; i < locations.length; i++){
        marker = new google.maps.Marker({
            position: new google.maps.LatLng(locations[i][1], locations[i][2]),
            map: map
        });
bounds.extend(marker.position);
}
map.fitBounds(bounds);

If anyone wants to use gvim as their diff tool on TortoiseGit, then this is what you need to enter into the text input for the path to the external diff tool:

path\to\gvim.exe -f -d -c "wincmd R" -c "wincmd R" -c "wincmd h" -c "wincmd J"

You need $event.currentTarget instead of $event.target.

*You can use layout_weight properties. If you want to take 70% of parent width you must set child layout_width property value 0dp, like android:layout_width="0dp"*

There are lots of solutions:

b = Arrays.copyOf(a, a.length);

Which allocates a new array, copies over the elements of a, and returns the new array.

Or

b = new int[a.length];
System.arraycopy(a, 0, b, 0, b.length);

Which copies the source array content into a destination array that you allocate yourself.

Or

b = a.clone();

which works very much like Arrays.copyOf(). See this thread.

Or the one you posted, if you reverse the direction of the assignment in the loop:

b[i] = a[i]; // NOT a[i] = b[i];

Problem solved at version 2.5.0b3

when I used the https url to push to the remote master, I met the same proble, I changed it to the SSH address, and everything resumed working flawlessly.

For unix systems only:

>>> import datetime
>>> d = datetime.date(2011,01,01)
>>> d.strftime("%s")  # <-- THIS IS THE CODE YOU WANT
'1293832800'

Note 1: dizzyf observed that this applies localized timezones. Don't use in production.

Note 2: Jakub Narebski noted that this ignores timezone information even for offset-aware datetime (tested for Python 2.7).

<string.h> is the old C header. C++ provides <string>, and then it should be referred to as std::string.

To install a service, run the InstallAndStart command as follows:

  SystemControl.InstallAndStart(
                                 "apache",
                                 "Apache Web Server",
                                 @"""c:\apache\bin\httpd.exe"" -k runservice"
  );

Make sure the account that is running the program has permission to install services. You can always 'Run As Administrator' on the program.

I have also included several commands for non-api access which do not install or remove services, but you can list them and control several (start, stop, restart). You really only need to elevate permissions for installing or removing services.

There are a couple of commands for getting and setting environment variables as well, such as OPENSSL_CONF or TEMP. For the most part, the parameters and method names should be pretty self-explanatory.

var collections = db.getCollectionNames();
for(var i = 0; i< collections.length; i++){    
   print('Collection: ' + collections[i]); // print the name of each collection
   db.getCollection(collections[i]).find().forEach(printjson); //and then print the json of each of its elements

I think this script might get what you want. It prints the name of each collection and then prints its elements in json.

As a supplement of the answer of Michael Parker, you can make getData accept a callback function to active the setState update the data:

componentWillMount : function () {
    var data = this.getData(()=>this.setState({data : data}));
},

The correct answer IMO is git clone --mirror. This will fully backup your repo.

Git clone mirror will clone the entire repository, notes, heads, refs, etc. and is typically used to copy an entire repository to a new git server. This will pull down an all branches and everything, the entire repository.

git clone --mirror [email protected]/your-repo.git

• Normally cloning a repo does not include all branches, only Master.

• Copying the repo folder will only "copy" the branches that have been pulled in...so by default that is Master branch only or other branches you have checked-out previously.

• The Git bundle command is also not what you want: "The bundle command will package up everything that would normally be pushed over the wire with a git push command into a binary file that you can email to someone or put on a flash drive, then unbundle into another repository." (From What's the difference between git clone --mirror and git clone --bare)

There is no built-in formula in excel, you have to add a vb script and permanently save it with your MS. Excel's installation as Add-In.

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)

It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.

Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)

you will see a Words equivalent of the numeric value.

make sure your doSomething function is not static.

I faced this issue, when I was supplying the executable folder with a, by the .exe requested DLL. In my case, the DLL I supplied to the .exe was searching for another necessary DLL which was not available. The searching DLL was not capable of telling that it can not find the necessary DLL.

You might check the DLLs you're loading and the dependencies of these DLL's.

I think the following way you can do it,

typedef struct
{
  int flag : 3;
} MyStruct;

For a simple file search you could use grep's -l and -r options:

grep -rl "mystring"

All the search is done by grep. Of course, if you need to select files on some other parameter, find is the correct solution:

find . -iname "*.php" -execdir grep -l "mystring" {} +

The execdir option builds each grep command per each directory, and concatenates filenames into only one command (+).

Microsoft guidelines as checked by FxCop discourage use of List<T> in public APIs - prefer IList<T>.

Incidentally, I now almost always declare one-dimensional arrays as IList<T>, which means I can consistently use the IList<T>.Count property rather than Array.Length. For example:

public interface IMyApi
{
    IList<int> GetReadOnlyValues();
}

public class MyApiImplementation : IMyApi
{
    public IList<int> GetReadOnlyValues()
    {
        List<int> myList = new List<int>();
        ... populate list
        return myList.AsReadOnly();
    }
}
public class MyMockApiImplementationForUnitTests : IMyApi
{
    public IList<int> GetReadOnlyValues()
    {
        IList<int> testValues = new int[] { 1, 2, 3 };
        return testValues;
    }
}

If you guys are facing "Permission Denial: starting Intent..." error or if the app is getting crash without any reason during launching the app - Then use this single line code in Manifest

android:exported="true"

Please be careful with finish(); , if you missed out it the app getting frozen. if its mentioned the app would be a smooth launcher.

finish();

The other solution only works for two activities that are in the same application. In my case, application B doesn't know class com.example.MyExampleActivity.class in the code, so compile will fail.

I searched on the web and found something like this below, and it works well.

Intent intent = new Intent();
intent.setComponent(new ComponentName("com.example", "com.example.MyExampleActivity"));
startActivity(intent);

You can also use the setClassName method:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.hotfoot.rapid.adani.wheeler.android", "com.hotfoot.rapid.adani.wheeler.android.view.activities.MainActivity");
startActivity(intent);
finish();

You can also pass the values from one app to another app :

Intent launchIntent = getApplicationContext().getPackageManager().getLaunchIntentForPackage("com.hotfoot.rapid.adani.wheeler.android.LoginActivity");
if (launchIntent != null) {
    launchIntent.putExtra("AppID", "MY-CHILD-APP1");
    launchIntent.putExtra("UserID", "MY-APP");
    launchIntent.putExtra("Password", "MY-PASSWORD");
    startActivity(launchIntent);
    finish();
} else {
    Toast.makeText(getApplicationContext(), " launch Intent not available", Toast.LENGTH_SHORT).show();
}

Real shows total turn-around time for a process; while User shows the execution time for user-defined instructions and Sys is for time for executing system calls!

Real time includes the waiting time also (the waiting time for I/O etc.)

Example of integer division using bash to divide $a by $b:

echo $((a/b))

I have created some sample code which creates new variables using a variety of ways that I can think of. It looks like the first 3 ways create values, and the last two create references.

package main

import "fmt"

type Config struct {
    host string
    port float64
}

func main() {
    //value
    var c1 Config
    c2 := Config{}
    c3 := *new(Config)

    //reference
    c4 := &Config{}
    c5 := new(Config)

    fmt.Println(&c1 == nil)
    fmt.Println(&c2 == nil)
    fmt.Println(&c3 == nil)
    fmt.Println(c4 == nil)
    fmt.Println(c5 == nil)

    fmt.Println(c1, c2, c3, c4, c5)
}

which outputs:

false
false
false
false
false
{ 0} { 0} { 0} &{ 0} &{ 0}

If you're open to using jQuery:

<script type="text/javascript">
 function fncsave()
 {
    $('#<%= savebtn.ClientID %>').click();
 }
</script>

Also, if you are using .NET 4 or better you can make the ClientIDMode == static and simplify the code:

<script type="text/javascript">
 function fncsave()
 {
    $("#savebtn").click();
 }
</script>

Reference: MSDN Article for Control.ClientIDMode

A class in HTML means that in order to set attributes to it in CSS, you simply need to add a period in front of it.
For example, the CSS code of that html code may be:

.clear {     height: 50px;     width: 25px; } 

Also, if you, as suggested by abiessu, are attempting to add the CSS clear: both; attribute to the div to prevent anything from floating to the left or right of this div, you can use this CSS code:

.clear {     clear: both; } 

psql does this, and if you start psql with:

psql -E

it will show you exactly what query is executed. In the case of finding foreign keys, it's:

SELECT conname,
  pg_catalog.pg_get_constraintdef(r.oid, true) as condef
FROM pg_catalog.pg_constraint r
WHERE r.conrelid = '16485' AND r.contype = 'f' ORDER BY 1

In this case, 16485 is the oid of the table I'm looking at - you can get that one by just casting your tablename to regclass like:

WHERE r.conrelid = 'mytable'::regclass

Schema-qualify the table name if it's not unique (or the first in your search_path):

WHERE r.conrelid = 'myschema.mytable'::regclass

It's not a direct answer to the question, however I would suggest in most cases to simply set multiple classes to each element:

<div class="myclass one"></div>
<div class="myclass two></div>
<div class="myclass three"></div>

In this way you can set rules for all myclass elements and then more specific rules for one, two and three.

.myclass { color: #f00; }

.two { font-weight: bold; }

etc.

SELECT *
FROM pg_settings
WHERE name = 'port';

Use the Array#join method (the argument to join is what to insert between the strings - in this case a space):

@arr.join(" ")

Stumbled on this page as well, and then found out this is possible with just javascript (no plugins like ActiveX or Flash), but just in chrome:

https://plus.google.com/+AddyOsmani/posts/Dk5UhZ6zfF3

Basically, they added support for a new attribute on the file input element "webkitdirectory". You can use it like this:

<input type="file" id="ctrl" webkitdirectory directory multiple/>

It allows you to select directories. The multiple attribute is a good fallback for browsers that support multiple file selection but not directory selection.

When you select a directory the files are available through the dom object for the control (document.getElementById('ctrl')), just like they are with the multiple attribute. The browsers adds all files in the selected directory to that list recursively.

You can already add the directory attribute as well in case this gets standardized at some point (couldn't find any info regarding that)

You can use Marker With Label option in google-maps-utility-library-v3.

Just refer https://code.google.com/p/google-maps-utility-library-v3/wiki/Libraries

Normally, When you copy a cell you will find the below statement written down in the status bar (in the bottom of your sheet)

"Select destination and Press Enter or Choose Paste"

Then you press whether Enter or choose paste to paste the value of the cell.

If you didn't press Esc afterwards you will be able to paste the value of the cell several times

Application.CutCopyMode = False does the same like the Esc button, if you removed it from your code you will find that you are able to paste the cell value several times again.

And if you closed the Excel without pressing Esc you will get the warning 'There is a large amount of information on the Clipboard....'

Your Ubuntu OS need to install library for mysql client sudo apt-get install libmysqlclient-dev

After That just install bundle or bundle install

Use dispatch group

dispatchGroup.enter()
FirstOperation(completion: { _ in
    dispatchGroup.leave()
})
dispatchGroup.enter()
SecondOperation(completion: { _ in
    dispatchGroup.leave()
})
dispatchGroup.wait() // Waits here on this thread until the two operations complete executing.

<select name="selectedFacilityId" ng-model="selectedFacilityId">
         <option ng-repeat="facility in facilities" value="{{facility.id}}">{{facility.name}}</option>
     </select>  

This is an example on how to use it.

You can change the tabs by ctrl-pgup and ctrl-pgdown. On that tab you came from the NERDTree is still selected and you can open another tab.

If you don't care about the order of the elements, I recommend ListAssert.assertEquals in junit-addons.

You have to be careful not to insert directly into your SERIAL or sequence field, otherwise your write will fail when the sequence reaches the inserted value:

-- Table: "test"

-- DROP TABLE test;

CREATE TABLE test
(
  "ID" SERIAL,
  "Rank" integer NOT NULL,
  "GermanHeadword" "text" [] NOT NULL,
  "PartOfSpeech" "text" NOT NULL,
  "ExampleSentence" "text" NOT NULL,
  "EnglishGloss" "text"[] NOT NULL,
  CONSTRAINT "PKey" PRIMARY KEY ("ID", "Rank")
)
WITH (
  OIDS=FALSE
);
-- ALTER TABLE test OWNER TO postgres;
 INSERT INTO test("Rank", "GermanHeadword", "PartOfSpeech", "ExampleSentence", "EnglishGloss")
           VALUES (1, '{"der", "die", "das", "den", "dem", "des"}', 'art', 'Der Mann küsst die Frau und das Kind schaut zu', '{"the", "of the" }');


 INSERT INTO test("ID", "Rank", "GermanHeadword", "PartOfSpeech", "ExampleSentence", "EnglishGloss")
           VALUES (2, 1, '{"der", "die", "das"}', 'pron', 'Das ist mein Fahrrad', '{"that", "those"}');

 INSERT INTO test("Rank", "GermanHeadword", "PartOfSpeech", "ExampleSentence", "EnglishGloss")
           VALUES (1, '{"der", "die", "das"}', 'pron', 'Die Frau, die nebenen wohnt, heißt Renate', '{"that", "who"}');

SELECT * from test; 

File -> Preferences -> Settings or just press Ctrl + , and search for spaces, then just deactivate this option:

I had to reopen the file so the changes would take effect.

For dynamically center

textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);

This will print each character in text

text = raw_input("Give some input:  ")
for i in range(0,len(text)):
   print(text[i])

"Note that you need to have image fully loaded first (otherwise ending up in having empty images), so in some cases you'd need to wrap handling into: bannerImage.addEventListener("load", function () {}); – yuga Nov 1 '17 at 13:04"

This is extremely IMPORTANT. One of the the options i'm exploring this afternoon is using javascript callback methods rather than addEventListeners since that doesn't seem to bind correctly either. Getting all the elements ready before page load WITHOUT a page refresh is critical.

If anyone can expand upon this please do - as in, did you use a settimeout, a wait, a callback, or an addEventListener method to get the desired result. Which one and why?

This should work

function updatePostID(val)
{
    document.getElementById('PostID').value = val;

    //and probably call document.forms[0].submit();
}

Then have a hidden field or other control for the PostID

@Html.Hidden("PostID", Model.addcomment.PostID)
//OR
@Html.HiddenFor(model => model.addcomment.PostID)

I had this same problem and it turns out I had a '\' instead of a '/' in the xml tag. It still gave the same error but just due to a syntax problem.

You need to alias the subquery.

SELECT name FROM (SELECT name FROM agentinformation) a  

or to be more explicit

SELECT a.name FROM (SELECT name FROM agentinformation) a  

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

The Canvas in WPF doesn't provide much automatic layout support. I try to steer clear of them for this reason (HorizontalAlignment and VerticalAlignment don't work as expected), but I got your code to work with these minor modifications (binding the Width and Height of the control to the canvas's ActualWidth/ActualHeight).

If you're not actually utilizing the features the canvas offers in terms of layout or Z-Order "squashing" (think of the flatten command in PhotoShop), I would consider using a control like a Grid instead so you don't end up having to learn the quirks of a control that works differently than you have come to expect with WPF.

To help understand what do $#, $0 and $1, ..., $n do, I use this script:

#!/bin/bash

for ((i=0; i<=$#; i++)); do
  echo "parameter $i --> ${!i}"
done

Running it returns a representative output:

$ ./myparams.sh "hello" "how are you" "i am fine"
parameter 0 --> myparams.sh
parameter 1 --> hello
parameter 2 --> how are you
parameter 3 --> i am fine

I would use GCJ (GNU Compiler for Java) in your situation. It's an AOT (ahead of time) compiler for Java, much like GCC is for C. Instead of interpreting code, or generating intermediate java code to be run at a later time by the Java VM, it generates machine code.

GCJ is available on almost any Linux system through its respective package manager (if available). After installation, the GCJ compiler should be added to the path so that it can be invoked through the terminal. If you're using Windows, you can download and install GCJ through Cygwin or MinGW.

I would strongly recommend, however, that you rewrite your source for another language that is meant to be compiled, such as C++. Java is meant to be a portable, interpreted language. Compiling it to machine code is completely against what the language was developed for.

GridLinked posted a PubSub solution which seems to be designed pretty well. The service can be found, here.

Also a diagram of their service:

Your method doesn't have any callbacks so there is no reason to use .CallBack(). You can simply return a Task with the desired values using .Returns() and Task.FromResult, e.g.:

MyType someValue=...;
mock.Setup(arg=>arg.DoSomethingAsync())        
    .Returns(Task.FromResult(someValue));

Update 2014-06-22

Moq 4.2 has two new extension methods to assist with this.

mock.Setup(arg=>arg.DoSomethingAsync())
    .ReturnsAsync(someValue);

mock.Setup(arg=>arg.DoSomethingAsync())        
    .ThrowsAsync(new InvalidOperationException());

Update 2016-05-05

As Seth Flowers mentions in the other answer, ReturnsAsync is only available for methods that return a Task<T>. For methods that return only a Task,

.Returns(Task.FromResult(default(object)))

can be used.

As shown in this answer, in .NET 4.6 this is simplified to .Returns(Task.CompletedTask);, e.g.:

mock.Setup(arg=>arg.DoSomethingAsync())        
    .Returns(Task.CompletedTask);

Fastest and general way to do this (line terminators, tabs will be processed as well). Regex powerful facilities don't really needed to solve this problem, but Regex can decrease performance.

                       new string
                           (stringToRemoveWhiteSpaces
                                .Where
                                (
                                    c => !char.IsWhiteSpace(c)
                                )
                                .ToArray<char>()
                           )

OR

                       new string
                           (stringToReplaceWhiteSpacesWithSpace
                                .Select
                                (
                                    c => char.IsWhiteSpace(c) ? ' ' : c
                                )
                                .ToArray<char>()
                           )

The question is relatively old, but I hope this post still might be relevant for others.

TL;DR: use AlarmManager to schedule a task, use IntentService, see the sample code here;

What this test-application(and instruction) is about:

Simple helloworld app, which sends you notification every 2 hours. Clicking on notification - opens secondary Activity in the app; deleting notification tracks.

When should you use it:

Once you need to run some task on a scheduled basis. My own case: once a day, I want to fetch new content from server, compose a notification based on the content I got and show it to user.

What to do:

1. First, let's create 2 activities: MainActivity, which starts notification-service and NotificationActivity, which will be started by clicking notification:

   activity_main.xml

   <?xml version="1.0" encoding="utf-8"?>
   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:padding="16dp">
       <Button
           android:id="@+id/sendNotifications"
           android:onClick="onSendNotificationsButtonClick"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:text="Start Sending Notifications Every 2 Hours!" />
   </RelativeLayout>
   

   MainActivity.java

   public class MainActivity extends AppCompatActivity {
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
       }
   
       public void onSendNotificationsButtonClick(View view) {
           NotificationEventReceiver.setupAlarm(getApplicationContext());
       }   
   }
   

   and NotificationActivity is any random activity you can come up with. NB! Don't forget to add both activities into AndroidManifest.

2. Then let's create WakefulBroadcastReceiver broadcast receiver, I called NotificationEventReceiver in code above.

   Here, we'll set up AlarmManager to fire PendingIntent every 2 hours (or with any other frequency), and specify the handled actions for this intent in onReceive() method. In our case - wakefully start IntentService, which we'll specify in the later steps. This IntentService would generate notifications for us.

   Also, this receiver would contain some helper-methods like creating PendintIntents, which we'll use later

   NB1! As I'm using WakefulBroadcastReceiver, I need to add extra-permission into my manifest: <uses-permission android:name="android.permission.WAKE_LOCK" />

   NB2! I use it wakeful version of broadcast receiver, as I want to ensure, that the device does not go back to sleep during my IntentService's operation. In the hello-world it's not that important (we have no long-running operation in our service, but imagine, if you have to fetch some relatively huge files from server during this operation). Read more about Device Awake here.

   NotificationEventReceiver.java

   public class NotificationEventReceiver extends WakefulBroadcastReceiver {
   
       private static final String ACTION_START_NOTIFICATION_SERVICE = "ACTION_START_NOTIFICATION_SERVICE";
       private static final String ACTION_DELETE_NOTIFICATION = "ACTION_DELETE_NOTIFICATION";
       private static final int NOTIFICATIONS_INTERVAL_IN_HOURS = 2;
   
       public static void setupAlarm(Context context) {
           AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
           PendingIntent alarmIntent = getStartPendingIntent(context);
           alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                   getTriggerAt(new Date()),
                   NOTIFICATIONS_INTERVAL_IN_HOURS * AlarmManager.INTERVAL_HOUR,
                   alarmIntent);
       }
   
       @Override
       public void onReceive(Context context, Intent intent) {
           String action = intent.getAction();
           Intent serviceIntent = null;
           if (ACTION_START_NOTIFICATION_SERVICE.equals(action)) {
               Log.i(getClass().getSimpleName(), "onReceive from alarm, starting notification service");
               serviceIntent = NotificationIntentService.createIntentStartNotificationService(context);
           } else if (ACTION_DELETE_NOTIFICATION.equals(action)) {
               Log.i(getClass().getSimpleName(), "onReceive delete notification action, starting notification service to handle delete");
               serviceIntent = NotificationIntentService.createIntentDeleteNotification(context);
           }
   
           if (serviceIntent != null) {
               startWakefulService(context, serviceIntent);
           }
       }
   
       private static long getTriggerAt(Date now) {
           Calendar calendar = Calendar.getInstance();
           calendar.setTime(now);
           //calendar.add(Calendar.HOUR, NOTIFICATIONS_INTERVAL_IN_HOURS);
           return calendar.getTimeInMillis();
       }
   
       private static PendingIntent getStartPendingIntent(Context context) {
           Intent intent = new Intent(context, NotificationEventReceiver.class);
           intent.setAction(ACTION_START_NOTIFICATION_SERVICE);
           return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
       }
   
       public static PendingIntent getDeleteIntent(Context context) {
           Intent intent = new Intent(context, NotificationEventReceiver.class);
           intent.setAction(ACTION_DELETE_NOTIFICATION);
           return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
       }
   }
   

3. Now let's create an IntentService to actually create notifications.

   There, we specify onHandleIntent() which is responses on NotificationEventReceiver's intent we passed in startWakefulService method.

   If it's Delete action - we can log it to our analytics, for example. If it's Start notification intent - then by using NotificationCompat.Builder we're composing new notification and showing it by NotificationManager.notify. While composing notification, we are also setting pending intents for click and remove actions. Fairly Easy.

   NotificationIntentService.java

   public class NotificationIntentService extends IntentService {
   
       private static final int NOTIFICATION_ID = 1;
       private static final String ACTION_START = "ACTION_START";
       private static final String ACTION_DELETE = "ACTION_DELETE";
   
       public NotificationIntentService() {
           super(NotificationIntentService.class.getSimpleName());
       }
   
       public static Intent createIntentStartNotificationService(Context context) {
           Intent intent = new Intent(context, NotificationIntentService.class);
           intent.setAction(ACTION_START);
           return intent;
       }
   
       public static Intent createIntentDeleteNotification(Context context) {
           Intent intent = new Intent(context, NotificationIntentService.class);
           intent.setAction(ACTION_DELETE);
           return intent;
       }
   
       @Override
       protected void onHandleIntent(Intent intent) {
           Log.d(getClass().getSimpleName(), "onHandleIntent, started handling a notification event");
           try {
               String action = intent.getAction();
               if (ACTION_START.equals(action)) {
                   processStartNotification();
               }
               if (ACTION_DELETE.equals(action)) {
                   processDeleteNotification(intent);
               }
           } finally {
               WakefulBroadcastReceiver.completeWakefulIntent(intent);
           }
       }
   
       private void processDeleteNotification(Intent intent) {
           // Log something?
       }
   
       private void processStartNotification() {
           // Do something. For example, fetch fresh data from backend to create a rich notification?
   
           final NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
           builder.setContentTitle("Scheduled Notification")
                   .setAutoCancel(true)
                   .setColor(getResources().getColor(R.color.colorAccent))
                   .setContentText("This notification has been triggered by Notification Service")
                   .setSmallIcon(R.drawable.notification_icon);
   
           PendingIntent pendingIntent = PendingIntent.getActivity(this,
                   NOTIFICATION_ID,
                   new Intent(this, NotificationActivity.class),
                   PendingIntent.FLAG_UPDATE_CURRENT);
           builder.setContentIntent(pendingIntent);
           builder.setDeleteIntent(NotificationEventReceiver.getDeleteIntent(this));
   
           final NotificationManager manager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
           manager.notify(NOTIFICATION_ID, builder.build());
       }
   }
   

4. Almost done. Now I also add broadcast receiver for BOOT_COMPLETED, TIMEZONE_CHANGED, and TIME_SET events to re-setup my AlarmManager, once device has been rebooted or timezone has changed (For example, user flown from USA to Europe and you don't want notification to pop up in the middle of the night, but was sticky to the local time :-) ).

   NotificationServiceStarterReceiver.java

   public final class NotificationServiceStarterReceiver extends BroadcastReceiver {
   
       @Override
       public void onReceive(Context context, Intent intent) {
           NotificationEventReceiver.setupAlarm(context);
       }
   }
   

5. We need to also register all our services, broadcast receivers in AndroidManifest:

   <?xml version="1.0" encoding="utf-8"?>
   <manifest xmlns:android="http://schemas.android.com/apk/res/android"
       package="klogi.com.notificationbyschedule">
   
       <uses-permission android:name="android.permission.INTERNET" />
       <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
       <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
       <uses-permission android:name="android.permission.WAKE_LOCK" />
   
       <application
           android:allowBackup="true"
           android:icon="@mipmap/ic_launcher"
           android:label="@string/app_name"
           android:supportsRtl="true"
           android:theme="@style/AppTheme">
           <activity android:name=".MainActivity">
               <intent-filter>
                   <action android:name="android.intent.action.MAIN" />
   
                   <category android:name="android.intent.category.LAUNCHER" />
               </intent-filter>
           </activity>
   
           <service
               android:name=".notifications.NotificationIntentService"
               android:enabled="true"
               android:exported="false" />
   
           <receiver android:name=".broadcast_receivers.NotificationEventReceiver" />
           <receiver android:name=".broadcast_receivers.NotificationServiceStarterReceiver">
               <intent-filter>
                   <action android:name="android.intent.action.BOOT_COMPLETED" />
                   <action android:name="android.intent.action.TIMEZONE_CHANGED" />
                   <action android:name="android.intent.action.TIME_SET" />
               </intent-filter>
           </receiver>
   
           <activity
               android:name=".NotificationActivity"
               android:label="@string/title_activity_notification"
               android:theme="@style/AppTheme.NoActionBar"/>
       </application>
   
   </manifest>
   

That's it!

The source code for this project you can find here. I hope, you will find this post helpful.

Even better: use the inspect.isclass function.

>>> import inspect
>>> class X(object):
...     pass
... 
>>> inspect.isclass(X)
True

>>> x = X()
>>> isinstance(x, X)
True
>>> y = 25
>>> isinstance(y, X)
False

Well it's a little bit out of question scope but in case you don't have an option for NSError you can always display the Low level error:

 NSLog(@"Error = %@ ",[NSString stringWithUTF8String:strerror(errno)]);

This is not obscure, it's the C++ initialization list syntax

Basically, in your case, x will be initialized with _x, y with _y, z with _z.

Whenever working with a React functional component, always keep the first letter of the name of the component in Uppercase in order to avoid these React Hooks errors.

In your case, you have named the component app, which should be changed to App, as I said above, to avoid the React Hook error.

You might have a lower project language level than your JDK.

Check if: "Projeckt structure/project/Project-> language level" is lower than your JDK. I had the same problem with JDK 9 and the language level was per default set to 6.

I set the Project Language Level to 9 and everything worked fine after that.

You might have the same issue.

final: final is a keyword. The variable decleared as final should be initialized only once and cannot be changed. Java classes declared as final cannot be extended. Methods declared as final cannot be overridden.

finally: finally is a block. The finally block always executes when the try block exits. This ensures that the finally block is executed even if an unexpected exception occurs. But finally is useful for more than just exception handling - it allows the programmer to avoid having cleanup code accidentally bypassed by a return, continue, or break. Putting cleanup code in a finally block is always a good practice, even when no exceptions are anticipated.

finalize: finalize is a method. Before an object is garbage collected, the runtime system calls its finalize() method. You can write system resources release code in finalize() method before getting garbage collected.

Fixed the issue by executing the following command:

to install gcc.

I had the same problem with a button doing a page refresh before doing the actual button_click event (so the button had to be clicked twice). This behavior happened after a server.transfer-command (server.transfer("testpage.aspx").

In this case, the solution was to replace the server.transfer-command with response-redirect (response.redirect("testpage.aspx").

For details on the differences between the two commands, see Server.Transfer Vs. Response.Redirect

Perhaps a couple of examples will help.

If you're building a class and you want it to act like a dictionary, you can define all the various __ __ methods necessary. But that's a bit of a pain. As an alternative, you can just define a few, and inherit (in addition to any other inheritance) from UserDict.DictMixin (moved to collections.DictMixin in py3k). This will have the effect of automatically defining all the rest of the dictionary api.

A second example: the GUI toolkit wxPython allows you to make list controls with multiple columns (like, say, the file display in Windows Explorer). By default, these lists are fairly basic. You can add additional functionality, such as the ability to sort the list by a particular column by clicking on the column header, by inheriting from ListCtrl and adding appropriate mixins.

In my case an unexpected error notice in the source code stopped the facebook crawler from parsing the (correctly set) og-meta tags.

I was using the HTTP_ACCEPT_LANGUAGE header, which worked fine for regular browser requests but not for the crawler, as it obviously won't use/set it.

Therefore, it was crucial for me to use the facebook's debugger feature See exactly what our scraper sees for your URL, as the error notice only could only be seen there (but not through the regular 'view source code'-browser feature).

I've used that notation before as well, with no ill side effects and no misunderstandings. It makes sense -- a string is just an array of characters, after all.

I had the same problem, but none of the solutions worked for me, because the message The system cannot find the file specified can be misleading in some special cases.

In my case, I use Notepad++ in combination with the registry redirect for notepad.exe. Unfortunately my path to Notepad++ in the registry was wrong.

So in fact the message The system cannot find the file specified was telling me, that it cannot find the application (Notepad++) associated with the file type(*.txt), not the file itself.

Change the loading order of your scripts so that function1 was defined before using it in ready callback.

Plus I always found it better to define ready callback as an anonymous method then named one.

If working with Basic4Android and looking for an easy fix to the problem, try this it works both Google maps and Openstreet even though OSM creates a bit of a messy result and thanx to [yndolok] for the google marker

The accepted answer is faulty, since the contents from the initial user folder are not moved using it. I am going to add another answer to correct it:

sudo usermod -d /newhome/username -m username

You don't need to create the folder with username and this will also move your files from the initial user folder to /newhome/username folder.

I have come accross the above issue. I have solved it as below. Its working fine for me.

1. Download the 'org.apache.commons.io.jar' file on navigating to [org.apache.commons.io.FileUtils] [ http://www.java2s.com/Code/Jar/o/Downloadorgapachecommonsiojar.htm ]

2. Extract the downloaded zip file to a specified folder.

3. Update the project properties by using below navigation Right click on project>Select Properties>Select Java Build Path> Click Libraries tab>Click Add External Class Folder button>Select the folder where zip file is extracted for org.apache.commons.io.FileUtils.zip file.

4. Now access the File Utils.

Anyone over here who wants his image to fit in full screen without any crop (in both portrait and landscape mode), use this:

image: {
    flex: 1,
    width: '100%',
    height: '100%',
    resizeMode: 'contain',
},

If you don't know the size of the string beforehand, you can dynamically allocate an array:

auto tab2 = std::make_unique<char[]>(temp.size() + 1);
std::strcpy(tab2.get(), temp.c_str());

Current date and time

$current_date_time = date('Y-m-d H:i:s');

15 min ago Date and time

$newTime = date("Y-m-d H:i:s",strtotime("+15 minutes", strtotime($current_date)));

For static files like pdfs, Word docs, etc. just use Express's static function in your config:

// Express config
var app = express().configure(function () {
    this.use('/public', express.static('public')); // <-- This right here
});

And then just put all your files inside that 'public' folder, for example:

/public/docs/my_word_doc.docx

And then a regular old link will allow the user to download it:

<a href="public/docs/my_word_doc.docx">My Word Doc</a>

You can see a detailed description here.

ini_set('display_errors', 1);

// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);

// Reporting E_NOTICE can be good too (to report uninitialized

error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);

// Report all errors except E_NOTICE
error_reporting(E_ALL & ~E_NOTICE);

// Report all PHP errors (see changelog)
error_reporting(E_ALL);

// Report all PHP errors
error_reporting(-1);

// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);

Here is the solution which worked for me.

OUTPUT: State of Cart Widget is updated, upon addition of items.

Create a globalKey for the widget you want to update by calling the trigger from anywhere

final GlobalKey<CartWidgetState> cartKey = GlobalKey();

Make sure it's saved in a file have global access such that, it can be accessed from anywhere. I save it in globalClass where is save commonly used variables through the app's state.

class CartWidget extends StatefulWidget {

  CartWidget({Key key}) : super(key: key);
  @override
  CartWidgetState createState() => CartWidgetState();
}

class CartWidgetState extends State<CartWidget> {
  @override
  Widget build(BuildContext context) {
    //return your widget
    return Container();
  }
}

Call your widget from some other class.

class HomeScreen extends StatefulWidget {

  HomeScreen ({Key key}) : super(key: key);
  @override
  HomeScreenState createState() => HomeScreen State();
}

class HomeScreen State extends State<HomeScreen> {
  @override
  Widget build(BuildContext context) {
    return ListView(
              children:[
                 ChildScreen(), 
                 CartWidget(key:cartKey)
              ]
            );
  }
}



class ChildScreen extends StatefulWidget {

  ChildScreen ({Key key}) : super(key: key);
  @override
  ChildScreenState createState() => ChildScreen State();
}

class ChildScreen State extends State<ChildScreen> {
  @override
  Widget build(BuildContext context) {
    return InkWell(
              onTap: (){
                // This will update the state of your inherited widget/ class
                if (cartKey.currentState != null)
                    cartKey.currentState.setState(() {});
              },
              child: Text("Update The State of external Widget"),
           );
  }
}

This approach also works with same hierarchy of Controller files:

$printReport = new PrintReportController;

$prinReport->getPrintReport();

Change that import to

from matplotlib.pyplot import *

Note that this style of imports (from X import *) is generally discouraged. I would recommend using the following instead:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])

Using REQUIRES_NEW is only relevant when the method is invoked from a transactional context; when the method is invoked from a non-transactional context, it will behave exactly as REQUIRED - it will create a new transaction.

That does not mean that there will only be one single transaction for all your clients - each client will start from a non-transactional context, and as soon as the the request processing will hit a @Transactional, it will create a new transaction.

So, with that in mind, if using REQUIRES_NEW makes sense for the semantics of that operation - than I wouldn't worry about performance - this would textbook premature optimization - I would rather stress correctness and data integrity and worry about performance once performance metrics have been collected, and not before.

On rollback - using REQUIRES_NEW will force the start of a new transaction, and so an exception will rollback that transaction. If there is also another transaction that was executing as well - that will or will not be rolled back depending on if the exception bubbles up the stack or is caught - your choice, based on the specifics of the operations. Also, for a more in-depth discussion on transactional strategies and rollback, I would recommend: «Transaction strategies: Understanding transaction pitfalls», Mark Richards.

Another way to get access to array.index(of: Any) is by declaring your object

import Foundation
class Model: NSObject {  }

Let's go simple ! :)

$.ajax({
    url: myUrl,
    context: $this, // $this == Current $element
    success: function(data) {
        $.proxy(publicMethods.update, this)(data); // this == Current $element
    }
});

How to differentiate between single clicks and double clicks on one and the same element?

If you don't need to mix them, you can rely on click and dblclick and each will do the job just fine.

A problem arises when trying to mix them: a dblclick event will actually trigger a click event as well, so you need to determine whether a single click is a "stand-alone" single click, or part of a double click.

In addition: you shouldn't use both click and dblclick on one and the same element:

It is inadvisable to bind handlers to both the click and dblclick events for the same element. The sequence of events triggered varies from browser to browser, with some receiving two click events before the dblclick and others only one. Double-click sensitivity (maximum time between clicks that is detected as a double click) can vary by operating system and browser, and is often user-configurable.
Source: https://api.jquery.com/dblclick/

Now on to the good news:

You can use the event's detail property to detect the number of clicks related to the event. This makes double clicks inside of click fairly easy to detect.

The problem remains of detecting single clicks and whether or not they're part of a double click. For that, we're back to using a timer and setTimeout.

Wrapping it all together, with use of a data attribute (to avoid a global variable) and without the need to count clicks ourselves, we get:

HTML:

<div class="clickit" style="font-size: 200%; margin: 2em; padding: 0.25em; background: orange;">Double click me</div>

<div id="log" style="background: #efefef;"></div>

JavaScript:

<script>
var clickTimeoutID;
$( document ).ready(function() {

    $( '.clickit' ).click( function( event ) {

        if ( event.originalEvent.detail === 1 ) {
            $( '#log' ).append( '(Event:) Single click event received.<br>' );

            /** Is this a true single click or it it a single click that's part of a double click?
             * The only way to find out is to wait it for either a specific amount of time or the `dblclick` event.
             **/
            clickTimeoutID = window.setTimeout(
                    function() {
                        $( '#log' ).append( 'USER BEHAVIOR: Single click detected.<br><br>' );
                    },
                    500 // how much time users have to perform the second click in a double click -- see accessibility note below.
                );

        } else if ( event.originalEvent.detail === 2 ) {
            $( '#log' ).append( '(Event:) Double click event received.<br>' );
            $( '#log' ).append( 'USER BEHAVIOR: Double click detected.<br>' );
            window.clearTimeout( clickTimeoutID ); // it's a dblclick, so cancel the single click behavior.
        } // triple, quadruple, etc. clicks are ignored.

    });

});
</script>

Notes about accessibility and double click speeds:

• As Wikipedia puts it "The maximum delay required for two consecutive clicks to be interpreted as a double-click is not standardized."
• No way of detecting the system's double-click speed in the browser.
• Seems the default is 500 ms and the range 100-900mms on Windows (source)
• Think of people with disabilities who set, in their OS settings, the double click speed to its slowest.
  • If the system double click speed is slower than our default 500 ms above, both the single- and double-click behaviors will be triggered.
  • Either don't use rely on combined single and double click on one and the same item.
  • Or: add a setting in the options to have the ability to increase the value.

It took a while to find a satisfying solution, I hope this helps!

@IBAction func calculateAclr(_ sender: Any) {
    if let addition = addition(arrayString: [txtBox1.text, txtBox2.text, txtBox3.text]) {
      print("Answer = \(addition)")
      lblAnswer.text = "\(addition)"
    }
}

func addition(arrayString: [Any?]) -> Int? {

    var answer:Int?
    for arrayElement in arrayString {
        if let stringValue = arrayElement, let intValue = Int(stringValue)  {
            answer = (answer ?? 0) + intValue
        }
    }

    return answer
}

In your pg_hba.conf file, I see some incorrect and confusing lines:

# fine, this allows all dbs, all users, to be trusted from 192.168.0.1/32
# not recommend because of the lax permissions
host    all        all         192.168.0.1/32        trust

# wrong, /128 is an invalid netmask for ipv4, this line should be removed
host    all        all         192.168.0.1/128       trust

# this conflicts with the first line
# it says that that the password should be md5 and not plaintext
# I think the first line should be removed
host    all        all         192.168.0.1/32        md5

# this is fine except is it unnecessary because of the previous line
# which allows any user and any database to connect with md5 password
host    chaosLRdb  postgres    192.168.0.1/32        md5

# wrong, on local lines, an IP cannot be specified
# remove the 4th column
local   all        all         192.168.0.1/32        trust

I suspect that if you md5'd the password, this might work if you trim the lines. To get the md5 you can use perl or the following shell script:

 echo -n 'chaos123' | md5sum
 > d6766c33ba6cf0bb249b37151b068f10  -

So then your connect line would like something like:

my $dbh = DBI->connect("DBI:PgPP:database=chaosLRdb;host=192.168.0.1;port=5433",
    "chaosuser", "d6766c33ba6cf0bb249b37151b068f10");

For more information, here's the documentation of postgres 8.X's pg_hba.conf file.

First:

I think you can do it 2 ways

http://our.api.com/Product/<id> : if you just want one record

http://our.api.com/Product : if you want all records

http://our.api.com/Product/<id1>,<id2> :as James suggested can be an option since what comes after the Product tag is a parameter

Or the one I like most is:

You can use the the Hypermedia as the engine of application state (HATEOAS) property of a RestFul WS and do a call http://our.api.com/Product that should return the equivalent urls of http://our.api.com/Product/<id> and call them after this.

Second

When you have to do queries on the url calls. I would suggest using HATEOAS again.

1) Do a get call to http://our.api.com/term/pumas/productType/clothing/color/black

2) Do a get call to http://our.api.com/term/pumas/productType/clothing,bags/color/black,red

3) (Using HATEOAS) Do a get call to `http://our.api.com/term/pumas/productType/ -> receive the urls all clothing possible urls -> call the ones you want (clothing and bags) -> receive the possible color urls -> call the ones you want

For references you can call

rails generate migration AddUserIdColumnToTable user:references

If in the future you need to add a general index you can launch this

rails g migration AddOrdinationNumberToTable ordination_number:integer:index

Generate code:

class AddOrdinationNumberToTable < ActiveRecord::Migration
  def change
   add_column :tables, :ordination_number, :integer
   add_index :tables, :ordination_number, unique: true
  end
end

You need to use the name of your form, as well as ng-disabled: Here's a demo on Plunker

<form name="myForm">
    <input name="myText" type="text" ng-model="mytext" required />
    <button ng-disabled="myForm.$invalid">Save</button>
</form>

If you're using Python 2.5, this won't work, but for people using 2.6 or 2.7, try

from __future__ import print_function

print("abcd", end='')
print("efg")

results in

abcdefg

For those using 3.x, this is already built-in.

Trying to write a REST API from scratch is not a simple task. There are many issues to factor and you will need to write a lot of code to process requests and data coming from the caller, authentication, retrieval of data and sending back responses.

Your best bet is to use a framework that already has this functionality ready and tested for you.

Some suggestions are:

Phalcon - REST API building - Easy to use all in one framework with huge performance

Apigility - A one size fits all API handling framework by Zend Technologies

Laravel API Building Tutorial

and many more. Simple searches on Bitbucket/Github will give you a lot of resources to start with.

Very basic, but does what you need without any addon modules or PS version requirements:

while ($true) {Clear-Host; gc E:\test.txt | select -last 3; sleep 2 }

this code once i write for just explain onChange event of select you can save this code as html and see output it works.and easy to understand for you.

<html>
    <head>
        <title>Register</title>
    </head>
    <body>
    <script>
        function show(){
            var option = document.getElementById("category").value;
            if(option == "Student")
                  {
                        document.getElementById("enroll1").style.display="block";
                  }
            if(option == "Parents")
                  {
                        document.getElementById("enroll1").style.display="none";
                  }
            if(option == "Guardians")
                  {
                        document.getElementById("enroll1").style.display="none";
                  }
        }

                        <td><input type="text" id="name" size=20 maxlength=20 value=""></td>
                    </tr>

                    </tr>

                    </tr>
                    <tr>
                        <td><label>Mobile No. </label></td>
                        <td><input type="number" id="mobile" size=20 maxlength=10 value=""></td>
                    </tr>
                    <tr>
                        <td><label>Address</label></td>
                        <td><textarea rows="2" cols="20"></textarea></td>
                    </tr>
                    <tr >
                        <td><label>Category</label></td>
                        <td><select id="category" onchange="show()">    <!--onchange show methos is call-->
                                <option value="Student">Student</option>

                                <option value="Guardians">Guardians</option>
                            </select>
                        </td>
                    </tr>

This goes also for statements like this (auto-formatted by PyCharm):

    return combine_sample_generators(sample_generators['train']), \
           combine_sample_generators(sample_generators['dev']), \
           combine_sample_generators(sample_generators['test'])

Which will give the same style-warning. In order to get rid of it I had to rewrite it to:

    return \
        combine_sample_generators(sample_generators['train']), \
        combine_sample_generators(sample_generators['dev']), \
        combine_sample_generators(sample_generators['test'])

Using .NET 4.5 (or .NET 4.0 by adding the Microsoft.Net.Http package from NuGet) there is an easier way to simulate form requests. Here is an example:

private async Task<System.IO.Stream> Upload(string actionUrl, string paramString, Stream paramFileStream, byte [] paramFileBytes)
{
    HttpContent stringContent = new StringContent(paramString);
    HttpContent fileStreamContent = new StreamContent(paramFileStream);
    HttpContent bytesContent = new ByteArrayContent(paramFileBytes);
    using (var client = new HttpClient())
    using (var formData = new MultipartFormDataContent())
    {
        formData.Add(stringContent, "param1", "param1");
        formData.Add(fileStreamContent, "file1", "file1");
        formData.Add(bytesContent, "file2", "file2");
        var response = await client.PostAsync(actionUrl, formData);
        if (!response.IsSuccessStatusCode)
        {
            return null;
        }
        return await response.Content.ReadAsStreamAsync();
    }
}

I figured out the issue. The linked server was created correctly. However, after the server was upgraded and switched the server name in sys.servers still had the old server name.

I had to drop the old server name and add the new server name to sys.servers on the new server

sp_dropserver 'Server_A'
GO
sp_addserver  'Server',local
GO

Put all radio buttons for a group in a container object like a Panel or a GroupBox. That will automatically group them together in Windows Forms.

You can use Strings replace method with a regular expression.

"Hello World ".replace(/ /g, "");

The replace() method returns a new string with some or all matches of a pattern replaced by a replacement. The pattern can be a string or a RegExp

RegExp

• / / - Regular expression matching spaces

• g - Global flag; find all matches rather than stopping after the first match

const str = "H    e            l l       o  World! ".replace(/ /g, "");_x000D_
document.getElementById("greeting").innerText = str;

<p id="greeting"><p>

If you're using 0 and an empty string '' and null to designate undefined you've got a data problem. Just update the columns and fix your schema.

UPDATE pt.incentive_channel
SET   pt.incentive_marketing = NULL
WHERE pt.incentive_marketing = '';

UPDATE pt.incentive_channel
SET   pt.incentive_advertising = NULL
WHERE pt.incentive_marketing = '';

UPDATE pt.incentive_channel
SET   pt.incentive_channel = NULL
WHERE pt.incentive_marketing = '';

This will make joining and selecting substantially easier moving forward.

CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(

I don't think it is possible to share a database link between more than one user but not all. They are either private (for one user only) or public (for all users).

A good way around this is to create a view in SCHEMA_B that exposes the table you want to access through the database link. This will also give you good control over who is allowed to select from the database link, as you can control the access to the view.

Do like this:

create database link db_link... as before;
create view mytable_view as select * from mytable@db_link;
grant select on mytable_view to myuser;

var fs = require("fs");
var filename = "./index.html";

function start(resp) {
    resp.writeHead(200, {
        "Content-Type": "text/html"
    });
    fs.readFile(filename, "utf8", function(err, data) {
        if (err) throw err;
        resp.write(data);
        resp.end();
    });
}
