To be short, use:

write-output "your text" | out-file -append -encoding utf8 "filename"

rawLapsData continues to point to the same array, even if you modify the contents of the array (e.g., add items, remove items, change an item).

During change detection, when Angular checks components' input properties for change, it uses (essentially) === for dirty checking. For arrays, this means the array references (only) are dirty checked. Since the rawLapsData array reference isn't changing, ngOnChanges() will not be called.

I can think of two possible solutions:

1. Implement ngDoCheck() and perform your own change detection logic to determine if the array contents have changed. (The Lifecycle Hooks doc has an example.)

2. Assign a new array to rawLapsData whenever you make any changes to the array contents. Then ngOnChanges() will be called because the array (reference) will appear as a change.

In your answer, you came up with another solution.

Repeating some comments here on the OP:

I still don't see how laps can pick up on the change (surely it must be using something equivalent to ngOnChanges() itself?) while map can't.

• In the laps component your code/template loops over each entry in the lapsData array, and displays the contents, so there are Angular bindings on each piece of data that is displayed.
• Even when Angular doesn't detect any changes to a component's input properties (using === checking), it still (by default) dirty checks all of the template bindings. When any of those change, Angular will update the DOM. That's what you are seeing.
• The maps component likely doesn't have any bindings in its template to its lapsData input property, right? That would explain the difference.

Note that lapsData in both components and rawLapsData in the parent component all point to the same/one array. So even though Angular doesn't notice any (reference) changes to the lapsData input properties, the components "get"/see any array contents changes because they all share/reference that one array. We don't need Angular to propagate these changes, like we would with a primitive type (string, number, boolean). But with a primitive type, any change to the value would always trigger ngOnChanges() – which is something you exploit in your answer/solution.

As you probably figured out by now object input properties have the same behavior as array input properties.

I've built a function that deals with plotting FFT of real signals. The extra bonus in my function relative to the previous answers is that you get the actual amplitude of the signal.

Also, because of the assumption of a real signal, the FFT is symmetric, so we can plot only the positive side of the x-axis:

import matplotlib.pyplot as plt
import numpy as np
import warnings


def fftPlot(sig, dt=None, plot=True):
    # Here it's assumes analytic signal (real signal...) - so only half of the axis is required

    if dt is None:
        dt = 1
        t = np.arange(0, sig.shape[-1])
        xLabel = 'samples'
    else:
        t = np.arange(0, sig.shape[-1]) * dt
        xLabel = 'freq [Hz]'

    if sig.shape[0] % 2 != 0:
        warnings.warn("signal preferred to be even in size, autoFixing it...")
        t = t[0:-1]
        sig = sig[0:-1]

    sigFFT = np.fft.fft(sig) / t.shape[0]  # Divided by size t for coherent magnitude

    freq = np.fft.fftfreq(t.shape[0], d=dt)

    # Plot analytic signal - right half of frequence axis needed only...
    firstNegInd = np.argmax(freq < 0)
    freqAxisPos = freq[0:firstNegInd]
    sigFFTPos = 2 * sigFFT[0:firstNegInd]  # *2 because of magnitude of analytic signal

    if plot:
        plt.figure()
        plt.plot(freqAxisPos, np.abs(sigFFTPos))
        plt.xlabel(xLabel)
        plt.ylabel('mag')
        plt.title('Analytic FFT plot')
        plt.show()

    return sigFFTPos, freqAxisPos


if __name__ == "__main__":
    dt = 1 / 1000

    # Build a signal within Nyquist - the result will be the positive FFT with actual magnitude
    f0 = 200  # [Hz]
    t = np.arange(0, 1 + dt, dt)
    sig = 1 * np.sin(2 * np.pi * f0 * t) + \
        10 * np.sin(2 * np.pi * f0 / 2 * t) + \
        3 * np.sin(2 * np.pi * f0 / 4 * t) +\
        7.5 * np.sin(2 * np.pi * f0 / 5 * t)

    # Result in frequencies
    fftPlot(sig, dt=dt)
    # Result in samples (if the frequencies axis is unknown)
    fftPlot(sig)

#Case 1: download file with small size.

• You can use url with format https://drive.google.com/uc?export=download&id=FILE_ID and then inputstream of file can be obtained directly.

#Case 2: download file with large size.

• You stuck a wall of a virus scan alert page returned. By parsing html dom element, I tried to get link with confirm code under button "Download anyway" but it didn't work. Its may required cookie or session info. enter image description here

SOLUTION:

• Finally I found solution for two above cases. Just need to put httpConnection.setDoOutput(true) in connection step to get a Json.

  )]}' { "disposition":"SCAN_CLEAN", "downloadUrl":"http:www...", "fileName":"exam_list_json.txt", "scanResult":"OK", "sizeBytes":2392}

Then, you can use any Json parser to read downloadUrl, fileName and sizeBytes.

• You can refer follow snippet, hope it help.

And

   public static FileDataSet readFileDataset(File file) throws IOException{
        FileInputStream is = new FileInputStream(file);
        JsonReader reader = new JsonReader(new InputStreamReader(is, "UTF-8"));

        reader.beginObject();

            if(name.equals("downloadUrl")){
                rs.setPath(reader.nextString());
            } else if(name.equals("fileName")){
                rs.setName(reader.nextString());
            } else if(name.equals("sizeBytes")){
                rs.setSize(reader.nextLong());
            } else {
                reader.skipValue();
            }
        }
        reader.endObject();
        return rs;

    }

Even better use implicit remoting to use a module from another Machine!

$s = New-PSSession Server-Name
Invoke-Command -Session $s -ScriptBlock {Import-Module ActiveDirectory}
Import-PSSession -Session $s -Module ActiveDirectory -Prefix REM

This will allow you to use the module off a remote PC for as long as the PSSession is connected.

In this instance, your div elements have been changed from block level elements to inline elements. A typical characteristic of inline elements is that they respect the whitespace in the markup. This explains why a gap of space is generated between the elements. (example)

There are a few solutions that can be used to solve this.

Method 1 - Remove the whitespace from the markup

Example 1 - Comment the whitespace out: (example)

<div>text</div><!--
--><div>text</div><!--
--><div>text</div><!--
--><div>text</div><!--
--><div>text</div>

Example 2 - Remove the line breaks: (example)

<div>text</div><div>text</div><div>text</div><div>text</div><div>text</div>

Example 3 - Close part of the tag on the next line (example)

<div>text</div
><div>text</div
><div>text</div
><div>text</div
><div>text</div>

Example 4 - Close the entire tag on the next line: (example)

<div>text
</div><div>text
</div><div>text
</div><div>text
</div><div>text
</div>

Method 2 - Reset the font-size

Since the whitespace between the inline elements is determined by the font-size, you could simply reset the font-size to 0, and thus remove the space between the elements.

Just set font-size: 0 on the parent elements, and then declare a new font-size for the children elements. This works, as demonstrated here (example)

#parent {
    font-size: 0;
}

#child {
    font-size: 16px;
}

This method works pretty well, as it doesn't require a change in the markup; however, it doesn't work if the child element's font-size is declared using em units. I would therefore recommend removing the whitespace from the markup, or alternatively floating the elements and thus avoiding the space generated by inline elements.

Method 3 - Set the parent element to display: flex

In some cases, you can also set the display of the parent element to flex. (example)

This effectively removes the spaces between the elements in supported browsers. Don't forget to add appropriate vendor prefixes for additional support.

.parent {
    display: flex;
}
.parent > div {
    display: inline-block;
    padding: 1em;
    border: 2px solid #f00;
}

.parent {_x000D_
    display: flex;_x000D_
}_x000D_
.parent > div {_x000D_
    display: inline-block;_x000D_
    padding: 1em;_x000D_
    border: 2px solid #f00;_x000D_
}

<div class="parent">_x000D_
    <div>text</div>_x000D_
    <div>text</div>_x000D_
    <div>text</div>_x000D_
    <div>text</div>_x000D_
    <div>text</div>_x000D_
</div>

Sides notes:

It is incredibly unreliable to use negative margins to remove the space between inline elements. Please don't use negative margins if there are other, more optimal, solutions.

For Bootstrap 3, you would need to use a custom wrapper and set its width to 100%.

.container-full {
  margin: 0 auto;
  width: 100%;
}

Here is a working example on Bootply

If you prefer not to add a custom class, you can acheive a very wide layout (not 100%) by wrapping everything inside a col-lg-12 (wide layout demo)

Update for Bootstrap 3.1

The container-fluid class has returned in Bootstrap 3.1, so this can be used to create a full width layout (no additional CSS required)..

I too had the same problem and resolved.

As per the above-mentioned solutions by others, I tried all the things and it does not solve my problem.

Even if you have two SDK locations, no need to worry about it and check whether your android home is set to Android studio SDK (If you have the Android repository and everything in that SDK location).

Solution:

• Go to Your project structure
• Select your modules
• Click the dependance tap on the right side
• Add library dependency
• "com.google.android.gms:play-service:+"

I hope it will solve your problem.

Simple 3-Liner

A simple way of doing this that I found as a comment by @awardak in Brandon Rude's answer:

new Thread( new Runnable() { @Override public void run() { 
  // Run whatever background code you want here.
} } ).start();

I'm not sure if, or how , this is better than using AsyncTask.execute but it seems to work for us. Any comments as to the difference would be appreciated.

Thanks, @awardak!

Google, as of now, cannot open w/out saving. As a workaround, I use IE Tab from the Chrome Store. It is an extension that runs IE - which does allow opening w/ out saving- inside of the Chrome browser application.

Not the best solution, but it's an effective "patch" for now.

I had this problem, and the cause was that I had not added the Microsoft.Owin.Host.SystemWeb NuGet package to my project. Although the code in my startup class was correct, it was not being executed.

So if you're trying to solve this problem, put a breakpoint in the code where you do the Unity registrations. If you don't hit it, your dependency injection isn't going to work.

Just been implementing something similar in Mongo v3.2.3 using Node v0.12.7 and v4.4.4 and used:

{ $gte: new Date(dateVar).toISOString() }

I'm passing in an ISODate (e.g. 2016-04-22T00:00:00Z) and this works for a .find() query with or without the toISOString function. But when using in an .aggregate() $match query it doesn't like the toISOString function!

I've run into that same issue as well. It's because you're closing your connection to the socket, but not the socket itself. The socket can enter a TIME_WAIT state (to ensure all data has been transmitted, TCP guarantees delivery if possible) and take up to 4 minutes to release.

It's certainly annoying, but it's not a bug. See the comment from @Vereb on this answer below on the use of SO_REUSEADDR.

All you need to do is change the string within the java.text.SimpleDateFormat constructor to: "MM-dd-yyyy HH:mm:ss".

Just use the appropriate letters to build the above string to match your input date.

A lot of times the first couple chars will be a magic number for various file formats. You could check for this in addition to your exception checking above.

from PHP manual:

str_replace — Replace all occurrences of the search string with the replacement string

I would go down that route, and then convert from string to float - floatval

p = Popen(['grep', 'f'], stdout=PIPE, stdin=PIPE, stderr=STDOUT)    
p.stdin.write('one\n')
time.sleep(0.5)
p.stdin.write('two\n')
time.sleep(0.5)
p.stdin.write('three\n')
time.sleep(0.5)
testresult = p.communicate()[0]
time.sleep(0.5)
print(testresult)

honoring font family, dynamic font I've concocted this abomination:

extension NSAttributedString
{
    convenience fileprivate init?(html: String, font: UIFont? = Font.dynamic(style: .subheadline))
    {
        guard let data = html.data(using: String.Encoding.utf8, allowLossyConversion: true) else {
        var totalString = html

            .AppleSystemUIFont I get in font.familyName does not work
         while -apple-system does:
         */
        var ffamily = "-apple-system"
        if let font = font {
            let lLDBsucks = font.familyName
            if !lLDBsucks.hasPrefix(".appleSystem") {
                ffamily = font.familyName
            }
            totalString = "<style>\nhtml * {font-family: \(ffamily) !important;}\n            </style>\n" + html
        }
        guard let data = totalString.data(using: String.Encoding.utf8, allowLossyConversion: true) else {
            return nil
        }
        assert(Thread.isMainThread)
        guard let attributedText = try?  NSAttributedString(data: data, options: [.documentType: NSAttributedString.DocumentType.html, .characterEncoding: String.Encoding.utf8.rawValue], documentAttributes: nil) else {
            return nil
        }
        let mutable = NSMutableAttributedString(attributedString: attributedText)
        if let font = font {
        do {
            var found = false
            mutable.beginEditing()
            mutable.enumerateAttribute(NSAttributedString.Key.font, in: NSMakeRange(0, attributedText.length), options: NSAttributedString.EnumerationOptions(rawValue: 0)) { (value, range, stop) in
                    if let oldFont = value as? UIFont {
                        let newsize = oldFont.pointSize * 15 * Font.scaleHeruistic / 12
                        let newFont = oldFont.withSize(newsize)
                        mutable.addAttribute(NSAttributedString.Key.font, value: newFont, range: range)
                        found = true
                    }
                }
                if !found {
                    // No font was found - do something else?
                }

            mutable.endEditing()
            
//            mutable.addAttribute(.font, value: font, range: NSRange(location: 0, length: mutable.length))
        }
        self.init(attributedString: mutable)
    }

}

alternatively you can use the versions this was derived from and set font on UILabel after setting attributedString

this will clobber the size and boldness encapsulated in the attributestring though

kudos for reading through all the answers up to here. You are a very patient man woman or child.

You can force grep to look at binary files with:

grep --binary-files=text

You might also want to add -o (--only-matching) so you don't get tons of binary gibberish that will bork your terminal.

This mimics the official Ruby trace, if that's important to you.

begin
  0/0  # or some other nonsense
rescue => e
  puts e.backtrace.join("\n\t")
       .sub("\n\t", ": #{e}#{e.class ? " (#{e.class})" : ''}\n\t")
end

Amusingly, it doesn't handle 'unhandled exception' properly, reporting it as 'RuntimeError', but the location is correct.

using System.Reflection;
{
    string version = Assembly.GetEntryAssembly().GetName().Version.ToString();
}

Remarks from MSDN http://msdn.microsoft.com/en-us/library/system.reflection.assembly.getentryassembly%28v=vs.110%29.aspx:

The GetEntryAssembly method can return null when a managed assembly has been loaded from an unmanaged application. For example, if an unmanaged application creates an instance of a COM component written in C#, a call to the GetEntryAssembly method from the C# component returns null, because the entry point for the process was unmanaged code rather than a managed assembly.

In Swift 3

let alertLogin = UIAlertController.init(title: "Your Title", message:"Your message", preferredStyle: .alert)
                                    alertLogin.addAction(UIAlertAction(title: "Done", style:.default, handler: { (AlertAction) in

                                    }))
                                    self.window?.rootViewController?.present(alertLogin, animated: true, completion: nil)

Hope this example helps too

I have done java coding in a similar way for the below json array example as follows :

following is the json data format : stored as "EMPJSONDATA.json"

[{"EMPNO":275172,"EMP_NAME":"Rehan","DOB":"29-02-1992","DOJ":"10-06-2013","ROLE":"JAVA DEVELOPER"},

{"EMPNO":275173,"EMP_NAME":"G.K","DOB":"10-02-1992","DOJ":"11-07-2013","ROLE":"WINDOWS ADMINISTRATOR"},

{"EMPNO":275174,"EMP_NAME":"Abiram","DOB":"10-04-1992","DOJ":"12-08-2013","ROLE":"PROJECT ANALYST"}

{"EMPNO":275174,"EMP_NAME":"Mohamed Mushi","DOB":"10-04-1992","DOJ":"12-08-2013","ROLE":"PROJECT ANALYST"}]

public class Jsonminiproject {

public static void main(String[] args) {

      JSONParser parser = new JSONParser();

    try {
        JSONArray a = (JSONArray) parser.parse(new FileReader("F:/JSON DATA/EMPJSONDATA.json"));
        for (Object o : a)
        {
            JSONObject employee = (JSONObject) o;

            Long no = (Long) employee.get("EMPNO");
            System.out.println("Employee Number : " + no);

            String st = (String) employee.get("EMP_NAME");
            System.out.println("Employee Name : " + st);

            String dob = (String) employee.get("DOB");
            System.out.println("Employee DOB : " + dob);

            String doj = (String) employee.get("DOJ");
            System.out.println("Employee DOJ : " + doj);

            String role = (String) employee.get("ROLE");
            System.out.println("Employee Role : " + role);

            System.out.println("\n");

        }


    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }




}

}

Here you go. You just need to use None (or alternatively np.newaxis) combined with broadcasting:

In [6]: data - vector[:,None]
Out[6]:
array([[0, 0, 0],
       [0, 0, 0],
       [0, 0, 0]])

In [7]: data / vector[:,None]
Out[7]:
array([[1, 1, 1],
       [1, 1, 1],
       [1, 1, 1]])

When you provide a path, it can be absolute/rooted, or relative. If you provide a relative path, it will be resolved by taking the working directory of the running process.

Example:

string text = File.ReadAllText("Some\\Path.txt"); // relative path

The above code has the same effect as the following:

string text = File.ReadAllText(
    Path.Combine(Environment.CurrentDirectory, "Some\\Path.txt"));

If you have files that are always going to be in the same location relative to your application, just include a relative path to them, and they should resolve correctly on different computers.

I specifically was looking for the XML representation for Android.Graphics.Color. I didn't find these, so here you are. More details are in the help document.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="sysBlack">#FF000000</color>
    <color name="sysBlue">#FF0000FF</color>
    <color name="sysCyan">#FF00FFFF</color>
    <color name="sysDkGray">#FF444444</color>
    <color name="sysGray">#FF888888</color>
    <color name="sysGreen">#FF00FF00</color>
    <color name="sysLtGray">#FFCCCCCC</color>
    <color name="sysMagenta">#FFFF00FF</color>
    <color name="sysRed">#FFFF0000</color>
    <color name="sysTransparent">#00000000</color>
    <color name="sysWhite">#FFFFFFFF</color>
    <color name="sysYellow">#FFFFFF00</color>
</resources>

Of course, this is used like this:

android:textColor="@color/sysGray"

try following code.

var uiview :UIView?

self.uiview = NSBundle.mainBundle().loadNibNamed("myXib", owner: self, options: nil)[0] as? UIView

Edit:

import UIKit

class TestObject: NSObject {

     var uiview:UIView?

    init()  {
        super.init()
       self.uiview = NSBundle.mainBundle().loadNibNamed("myXib", owner: self, options: nil)[0] as? UIView
    }


}

jQuery provides a .text() method that can be used in any browser. For example:

$('#myElement').text("Foo");

You go to your "device manager", find your "network adapters", then should find the virtual wifi adapter, then right click it and enable it. After that, you start your cmd with admin privileges, then try:

netsh wlan start hostednetwork

I'm a total noob but I reinstalled over the codeblocks giving me these "Can't find file executable in your configured search path for gnc gcc compiler" errors by downloading:

codeblocks-20.03mingw-setup.exe

(IMPORTANT: make sure it has the "mingw" in the file download name, that has the compiler build that is required to compile the code which doesn't automatically comes with the main codeblocks editor software download because codeblocks already assumes you already have another compiler installed on your computer {visual studio 2019 or such}).

Then when I created a new project (console application) and used the defaults to quickly test it out.

It gave me errors.

So I went to Settings > Compiler > Selected Compiler set to: GNU GCC Compiler > Click on the "Tooolchain executables" tab > Click on Auto-Detect > Should say "C:\Progam Files\CodeBlocks\MinGW" > Click OK.

Build and run a simple hello world code.

Should work! If not, look for the "MingGW" in the C:\Program Files\CodeBlocks and select it.

cat db.dump | docker exec ... way didn't work for my dump (~2Gb). It took few hours and ended up with out-of-memory error.

Instead, I cp'ed dump into container and pg_restore'ed it from within.

Assuming that container id is CONTAINER_ID and db name is DB_NAME:

# copy dump into container
docker cp local/path/to/db.dump CONTAINER_ID:/db.dump

# shell into container
docker exec -it CONTAINER_ID bash

# restore it from within
pg_restore -U postgres -d DB_NAME --no-owner -1 /db.dump

a thorough reading of jQuery AJAX cross domain seems to indicate that the server you are querying is returning a header string that prohibits cross-domain json requests. Check the headers of the response you are receiving to see if the Access-Control-Allow-Origin header is set, and whether its value restricts cross-domain requests to the local host.

One of alternatives is MSYS2 , in another words "MinGW-w64"/Git Bash. You can simply ssh to Unix machines and run most of linux commands from it. Also install tmux!

To install tmux in MSYS2:

run command pacman -S tmux

To run tmux on Git Bash:

install MSYS2 and copy tmux.exe and msys-event-2-1-6.dll from MSYS2 folder C:\msys64\usr\bin to your Git Bash directory C:\Program Files\Git\usr\bin.

The given answer is far from complete. In fact, it is so far from complete that it tends to lead the reader to believe that this answer is OS dependent when it isn't. It also isn't something which is programming language dependent (as some commentators have suggested). I'm going to add more information in order to make this more clear. First, lets give the list of current new line variations (as in, what they've been since 1999):

• \r\n is only used on Windows Notepad, the DOS command line, most of the Windows API and in some (older) Windows apps.
• \n is used for all other systems, applications and the Internet.

You'll notice that I've put most Windows apps in the \n group which may be slightly controversial but before you disagree with this statement, please grab a UNIX formatted text file and try it in 10 web friendly Windows applications of your choice (which aren't listed in my exceptions above). What percentage of them handled it just fine? You'll find that they (practically) all implement auto detection of line endings or just use \n because, while Windows may use \r\n, the Internet uses \n. Therefore, it is best practice for applications to use \n alone if you want your output to be Internet friendly.

PHP also defines a newline character called PHP_EOL. This constant is set to the OS specific newline string for the machine PHP is running on (\r\n for Windows and \n for everything else). This constant is not very useful for webpages and should be avoided for HTML output or for writing most text to files. It becomes VERY useful when we move to command line output from PHP applications because it will allow your application to output to a terminal Window in a consistent manner across all supported OSes.

If you want your PHP applications to work from any server they are placed on, the two biggest things to remember are that you should always just use \n unless it is terminal output (in which case you use PHP_EOL) and you should also ALWAYS use / for your path separator (not \).

The even longer explanation:

An application may choose to use whatever line endings it likes regardless of the default OS line ending style. If I want my text editor to print a newline every time it encounters a period that is no harder than using the \n to represent a newline because I'm interpreting the text as I display it anyway. IOW, I'm fiddling around with measuring the width of each character so it knows where to display the next so it is very simple to add a statement saying that if the current char is a period then perform a newline action (or if it is a \n then display a period).

Aside from the null terminator, no character code is sacred and when you write a text editor or viewer you are in charge of translating the bits in your file into glyphs (or carriage returns) on the screen. The only thing that distinguishes a control character such as the newline from other characters is that most font sets don't include them (meaning they don't have a visual representation available).

That being said, if you are working at a higher level of abstraction then you probably aren't making your own textbox controls. If this is the case then you're stuck with whatever line ending that control makes available to you. Even in this case it is a simple matter to automatically detect the line ending style of any string and make the conversion before you load your text into the control and then undo it when you read from that control. Meaning, that if you're a desktop application dev and your application doesn't recognize \n as a newline then it isn't a very friendly application and you really have no excuse because it isn't hard to make it the right way. It also means that whomever wrote Notepad should be ashamed of himself because it really is very easy to do much better and so many people suffer through using it every day.

def convert(camel_str):
    temp_list = []
    for letter in camel_str:
        if letter.islower():
            temp_list.append(letter)
        else:
            temp_list.append('_')
            temp_list.append(letter)
    result = "".join(temp_list)
    return result.lower()

In addition to the other options, in at least IntelliJ IDEA 2017 Ultimate, WebStorm 2020.2, and probably a ton of other versions, you can do it in a single shortcut.

Edit preferences, search for Select in Project View, and under Keymap, view the mapped shortcut or map one of your choice.

On the Mac, Ctrl + Option + L is not already used, and is the same shortcut as Visual Studio for Windows uses natively (Ctrl + Alt + L, so that could be a good choice.

After several month without real solution for this problem, I suppose that the best solution is to upgrade the application to .NET framework 4.0, which is supported by Windows 8, Windows 10 and Windows 2012 Server by default and it is still available as offline installation for Windows XP.

I would try to connect to your Sharepoint site with this tool here. If that works you can be sure that the problem is in your code / configuration. That maybe does not solve your problem immediately but it rules out that there is something wrong with the server. Assuming that it does not work I would investigate the following:

• Does your user really have enough rights on the site?
• Is there a proxy that interferes? (Your configuration looks a bit like there is a proxy. Can you bypass it?)

I think there is nothing wrong with using security mode Transport, but I am not so sure about the proxyCredentialType="Ntlm", maybe this should be set to None.

You can configure your log4j file with the category tag like this (with a console appender for the example):

<appender name="console" class="org.apache.log4j.ConsoleAppender">
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%d{yy-MM-dd HH:mm:ss} %p %c - %m%n" />
    </layout>
</appender>
<category name="org.hibernate">
    <priority value="WARN" />
</category>
<root>
    <priority value="INFO" />
    <appender-ref ref="console" />
</root>

So every warning, error or fatal message from hibernate will be displayed, nothing more. Also, your code and library code will be in info level (so info, warn, error and fatal)

To change log level of a library, just add a category, for example, to desactive spring info log:

<category name="org.springframework">
    <priority value="WARN" />
</category>

Or with another appender, break the additivity (additivity default value is true)

<category name="org.springframework" additivity="false">
    <priority value="WARN" />
    <appender-ref ref="anotherAppender" />
</category>

And if you don't want that hibernate log every query, set the hibernate property show_sql to false.

In my strange case, Intellij remembers forever about my project even if I delete .iml... Thus I did the following:

1. Close project. Delete the .iml file.
2. Rename my project directory (say my_proj) to my_proj_backup.
3. (Possibly not needed) Open my_proj_backup in Intellij and close.
4. Create an empty directory called my_proj, and open it in Intellij. Then close it.
5. Remove the my_proj and move my_proj_backup back to my_proj. Then open my_proj in Intellij.

Then it happily forgot the old my_proj :)

//Method for Smaller Number Range:
Integer.parseInt("abc",16);

//Method for Bigger Number Range.
Long.parseLong("abc",16);

//Method for Biggest Number Range.
new BigInteger("abc",16);

For me a typical while loop will be something like this:

xBool = True
# A counter to force a condition (eg. yCount = some integer value)

while xBool:
    # set up the condition (eg. if yCount > 0):
        (Do something)
        yCount = yCount - 1
    else:
        # (condition is not met, set xBool False)
        xBool = False

I could include a for..loop within the while loop as well, if situation so warrants, for looping through another set of condition.

Module named importlib allow to access to import internals. Especially, it provide function importlib.reload():

import importlib
importlib.reload(my_module)

In contrary of %autoreload, importlib.reload() also reset global variables set in module. In most cases, it is what you want.

importlib is only available since Python 3.1. For older version, you have to use module imp.

You can Use this to make the background transparent

convert test.png -background rgba(0,0,0,0) test1.png

The above gives the prefect transparent background

$url="http://www.google.co.in/intl/en_com/images/srpr/logo1w.png";
$contents=file_get_contents($url);
$save_path="/path/to/the/dir/and/image.jpg";
file_put_contents($save_path,$contents);

you must have allow_url_fopen set to on

You can use the annotate command to place text annotations at any x and y values you want. To place them exactly at the data points you could do this

import numpy
from matplotlib import pyplot

x = numpy.arange(10)
y = numpy.array([5,3,4,2,7,5,4,6,3,2])

fig = pyplot.figure()
ax = fig.add_subplot(111)
ax.set_ylim(0,10)
pyplot.plot(x,y)
for i,j in zip(x,y):
    ax.annotate(str(j),xy=(i,j))

pyplot.show()

If you want the annotations offset a little, you could change the annotate line to something like

ax.annotate(str(j),xy=(i,j+0.5))

According to this page, in IE you need:

event.cancelBubble = true

As soon as I disabled the DuckDuckGo Privacy Essentials plugin it disappeared. Bit annoying as the fonts I was serving was from localhost so shouldn't be anything to do with a slow network connection.

Simple ways to check an empty dict are below:

        a= {}

    1. if a == {}:
           print ('empty dict')
    2. if not a:
           print ('empty dict')

Although method 1st is more strict as when a = None, method 1 will provide correct result but method 2 will give an incorrect result.

After almost 9 years here's a generic solution:

module CreateModuleFunctions
  def self.included(base)
    base.instance_methods.each do |method|
      base.module_eval do
        module_function(method)
        public(method)
      end
    end
  end
end

RSpec.describe CreateModuleFunctions do
  context "when included into a Module" do
    it "makes the Module's methods invokable via the Module" do
      module ModuleIncluded
        def instance_method_1;end
        def instance_method_2;end

        include CreateModuleFunctions
      end

      expect { ModuleIncluded.instance_method_1 }.to_not raise_error
    end
  end
end

The unfortunate trick you need to apply is to include the module after the methods have been defined. Alternatively you may also include it after the context is defined as ModuleIncluded.send(:include, CreateModuleFunctions).

Or you can use it via the reflection_utils gem.

spec.add_dependency "reflection_utils", ">= 0.3.0"

require 'reflection_utils'
include ReflectionUtils::CreateModuleFunctions

But you might also want to look into a very different approach, listening for file-system events.

In Windows, you need to set node.js folder path into system variables or user variables.

1) open Control Panel -> System and Security -> System -> Advanced System Settings -> Environment Variables

2) in "User variables" or "System variables" find variable PATH and add node.js folder path as value. Usually it is C:\Program Files\nodejs;. If variable doesn't exists, create it.

3) Restart your IDE or computer.

It is useful add also "npm" and "Git" paths as variable, separated by semicolon.

This was a real issue for me, and quite a sneaky problem to try and remedy...

The problem I had was that a module that was installed on my WiFi adapter was conflicting with the Microsoft Virtual Adapter (or whatever it's actually called).

To fix it:

1. Hold the Windows Key + Push R
2. Type: ncpa.cpl in to the box, and hit OK.
3. Identify the network adapter you want to use for the hostednetwork, right-click it, and select Properties.
4. You'll see a big box in the middle of the properties window, under the heading The connection uses the following items:. Look down the list for anything that seems out of the ordinary, and uncheck it. Hit OK.
5. Try running the netsh wlan start hostednetwork command again.
6. Repeat steps 4 and 5 as necessary.

In my case my adapter was running a module called SoftEther Lightweight Network Protocol, which I believe is used to help connect to VPN Gate VPN servers via the SoftEther software.

If literally nothing else works, then I'd suspect something similar to the problem I encountered, namely that a module on your network adapter is interfering with the hostednetwork aspect of your driver.

If you are still getting the error after you have done with all above steps, go to your projects bootstrap->cache->config.php remove the provider & aliases entries from the cached array manually.

In Scala you can use implicits to add the methods isEmpty() and nonEmpty() to the DataFrame API, which will make the code a bit nicer to read.

object DataFrameExtensions {
  implicit def extendedDataFrame(dataFrame: DataFrame): ExtendedDataFrame = 
    new ExtendedDataFrame(dataFrame: DataFrame)

  class ExtendedDataFrame(dataFrame: DataFrame) {
    def isEmpty(): Boolean = dataFrame.head(1).isEmpty // Any implementation can be used
    def nonEmpty(): Boolean = !isEmpty
  }
}

Here, other methods can be added as well. To use the implicit conversion, use import DataFrameExtensions._ in the file you want to use the extended functionality. Afterwards, the methods can be used directly as so:

val df: DataFrame = ...
if (df.isEmpty) {
  // Do something
}

My own implementation of generic restTemplate call:

private <REQ, RES> RES queryRemoteService(String url, HttpMethod method, REQ req, Class reqClass) {
    RES result = null;
    try {
        long startMillis = System.currentTimeMillis();

        // Set the Content-Type header
        HttpHeaders requestHeaders = new HttpHeaders();
        requestHeaders.setContentType(new MediaType("application","json"));            

        // Set the request entity
        HttpEntity<REQ> requestEntity = new HttpEntity<>(req, requestHeaders);

        // Create a new RestTemplate instance
        RestTemplate restTemplate = new RestTemplate();

        // Add the Jackson and String message converters
        restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
        restTemplate.getMessageConverters().add(new StringHttpMessageConverter());

        // Make the HTTP POST request, marshaling the request to JSON, and the response to a String
        ResponseEntity<RES> responseEntity = restTemplate.exchange(url, method, requestEntity, reqClass);
        result = responseEntity.getBody();
        long stopMillis = System.currentTimeMillis() - startMillis;

        Log.d(TAG, method + ":" + url + " took " + stopMillis + " ms");
    } catch (Exception e) {
         Log.e(TAG, e.getMessage());
    }
    return result;
}

To add some context, I'm consuming RESTful service with this, hence all requests and responses are wrapped into small POJO like this:

public class ValidateRequest {
  User user;
  User checkedUser;
  Vehicle vehicle;
}

and

public class UserResponse {
  User user;
  RequestResult requestResult;
}

Method which calls this is the following:

public User checkUser(User user, String checkedUserName) {
    String url = urlBuilder()
            .add(USER)
            .add(USER_CHECK)
            .build();

    ValidateRequest request = new ValidateRequest();
    request.setUser(user);
    request.setCheckedUser(new User(checkedUserName));

    UserResponse response = queryRemoteService(url, HttpMethod.POST, request, UserResponse.class);
    return response.getUser();
}

And yes, there's a List dto-s as well.

If you know the group id of X, you can use this command to redownload all of X and it's dependencies

mvn clean dependency:purge-local-repository -DresolutionFuzziness=org.id.of.x

It does the same thing as the other answers that propose using dependency:purge-local-repository, but it only deletes and redownloads everything related to X.

something like

movie.setStopDate(movie.getStartDate() + movie.getDurationInMinutes()* 60000);

There are many problems in your query.
This is a modified version of your code

string connetionString = null;
string sql = null;

// All the info required to reach your db. See connectionstrings.com
connetionString = "Data Source=UMAIR;Initial Catalog=Air; Trusted_Connection=True;" ;

// Prepare a proper parameterized query 
sql = "insert into Main ([Firt Name], [Last Name]) values(@first,@last)";

// Create the connection (and be sure to dispose it at the end)
using(SqlConnection cnn = new SqlConnection(connetionString))
{
    try
    {
       // Open the connection to the database. 
       // This is the first critical step in the process.
       // If we cannot reach the db then we have connectivity problems
       cnn.Open();

       // Prepare the command to be executed on the db
       using(SqlCommand cmd = new SqlCommand(sql, cnn))
       {
           // Create and set the parameters values 
           cmd.Parameters.Add("@first", SqlDbType.NVarChar).Value = textbox2.text;
           cmd.Parameters.Add("@last", SqlDbType.NVarChar).Value = textbox3.text;

           // Let's ask the db to execute the query
           int rowsAdded = cmd.ExecuteNonQuery();
           if(rowsAdded > 0) 
              MessageBox.Show ("Row inserted!!" + );
           else
              // Well this should never really happen
              MessageBox.Show ("No row inserted");

       }
    }
    catch(Exception ex)
    {
        // We should log the error somewhere, 
        // for this example let's just show a message
        MessageBox.Show("ERROR:" + ex.Message);
    }
}

• The column names contain spaces (this should be avoided) thus you need square brackets around them
• You need to use the using statement to be sure that the connection will be closed and resources released
• You put the controls directly in the string, but this don't work
• You need to use a parametrized query to avoid quoting problems and sqlinjiection attacks
• No need to use a DataAdapter for a simple insert query
• Do not use AddWithValue because it could be a source of bugs (See link below)

Apart from this, there are other potential problems. What if the user doesn't input anything in the textbox controls? Do you have done any checking on this before trying to insert? As I have said the fields names contain spaces and this will cause inconveniences in your code. Try to change those field names.

This code assumes that your database columns are of type NVARCHAR, if not, then use the appropriate SqlDbType enum value.

Please plan to switch to a more recent version of NET Framework as soon as possible. The 1.1 is really obsolete now.

And, about AddWithValue problems, this article explain why we should avoid it. Can we stop using AddWithValue() already?

Mismatch happens when you don't use the numeric ID. Project ID IS NOT SENDER ID!! It took me 9 hours to figure this out. For all the confusion created by google, check the following link to get numeric id.

https://console.cloud.google.com

instead of

https://console.developers.google.com

Hope it helps!!

Update:- Things have changed again. Now the sender id is with firebase.

Go to https://console.firebase.google.com and select your project. Under settings -> cloud messaging, you can find the sender id.

And it works!

I was in the same boat as you recently, and here is what I did:

1. I used the phpwebsockets code as a reference for how to structure the server-side code. (You seem to already be doing this, and as you noted, the code doesn't actually work for a variety of reasons.)

2. I used PHP.net to read the details about every socket function used in the phpwebsockets code. By doing this, I was finally able to understand how the whole system works conceptually. This was a pretty big hurdle.

3. I read the actual WebSocket draft. I had to read this thing a bunch of times before it finally started to sink in. You will likely have to go back to this document again and again throughout the process, as it is the one definitive resource with correct, up-to-date information about the WebSocket API.

4. I coded the proper handshake procedure based on the instructions in the draft in #3. This wasn't too bad.

5. I kept getting a bunch of garbled text sent from the clients to the server after the handshake and I couldn't figure out why until I realized that the data is encoded and must be unmasked. The following link helped me a lot here: (original link broken) Archived copy.

   Please note that the code available at this link has a number of problems and won't work properly without further modification.

6. I then came across the following SO thread, which clearly explains how to properly encode and decode messages being sent back and forth: How can I send and receive WebSocket messages on the server side?

   This link was really helpful. I recommend consulting it while looking at the WebSocket draft. It'll help make more sense out of what the draft is saying.

7. I was almost done at this point, but had some issues with a WebRTC app I was making using WebSocket, so I ended up asking my own question on SO, which I eventually solved: What is this data at the end of WebRTC candidate info?

8. At this point, I pretty much had it all working. I just had to add some additional logic for handling the closing of connections, and I was done.

That process took me about two weeks total. The good news is that I understand WebSocket really well now and I was able to make my own client and server scripts from scratch that work great. Hopefully the culmination of all that information will give you enough guidance and information to code your own WebSocket PHP script.

Good luck!

Edit: This edit is a couple of years after my original answer, and while I do still have a working solution, it's not really ready for sharing. Luckily, someone else on GitHub has almost identical code to mine (but much cleaner), so I recommend using the following code for a working PHP WebSocket solution:
https://github.com/ghedipunk/PHP-Websockets/blob/master/websockets.php

Edit #2: While I still enjoy using PHP for a lot of server-side related things, I have to admit that I've really warmed up to Node.js a lot recently, and the main reason is because it's better designed from the ground up to handle WebSocket than PHP (or any other server-side language). As such, I've found recently that it's a lot easier to set up both Apache/PHP and Node.js on your server and use Node.js for running the WebSocket server and Apache/PHP for everything else. And in the case where you're on a shared hosting environment in which you can't install/use Node.js for WebSocket, you can use a free service like Heroku to set up a Node.js WebSocket server and make cross-domain requests to it from your server. Just make sure if you do that to set your WebSocket server up to be able to handle cross-origin requests.

index(substring [, offset]) ? fixnum or nil
index(regexp [, offset]) ? fixnum or nil

Returns the index of the first occurrence of the given substring or pattern (regexp) in str. Returns nil if not found. If the second parameter is present, it specifies the position in the string to begin the search.

"hello".index('e')             #=> 1
"hello".index('lo')            #=> 3
"hello".index('a')             #=> nil
"hello".index(?e)              #=> 1
"hello".index(/[aeiou]/, -3)   #=> 4

Another way besides @Nahush's answer, if you are already using Express framework in the project then you can avoid using Nginx for reverse-proxy.

A simpler way is to use express-http-proxy

1. run npm run build to create the bundle.

   var proxy = require('express-http-proxy');
   
   var app = require('express')();
   
   //define the path of build
   
   var staticFilesPath = path.resolve(__dirname, '..', 'build');
   
   app.use(express.static(staticFilesPath));
   
   app.use('/api/api-server', proxy('www.api-server.com'));
   

Use "/api/api-server" from react code to call the API.

So, that browser will send request to the same host which will be internally redirecting the request to another server and the browser will feel that It is coming from the same origin ;)

This variant looks more simple and elegant.

CollectionType typeReference =
    TypeFactory.defaultInstance().constructCollectionType(List.class, Dto.class);
List<Dto> resultDto = objectMapper.readValue(content, typeReference);

Make sure your refs for pushing are correct. This tutorial is pretty great, right from the documentation:

http://wiki.eclipse.org/EGit/User_Guide#GitHub_Tutorial

You can clone directly from GitHub, you choose where you clone that repository. And when you import that repository to Eclipse, you choose what refspec to push into upstream.

Click on the Git Repository workspace view, and make sure your remote refs are valid. Make sure you are pointing to the right local branch and pushing to the correct remote branch.

If you don't need to use reflection and you have an object, you can use this:

if(myObject is IMyInterface )
{
 // it's implementing IMyInterface
}

As of Node.js v6.0.0 using the constructor method has been deprecated and the following method should instead be used to construct a new buffer from a base64 encoded string:

var b64string = /* whatever */;
var buf = Buffer.from(b64string, 'base64'); // Ta-da

For Node.js v5.11.1 and below

Construct a new Buffer and pass 'base64' as the second argument:

var b64string = /* whatever */;
var buf = new Buffer(b64string, 'base64'); // Ta-da

If you want to be clean, you can check whether from exists :

if (typeof Buffer.from === "function") {
    // Node 5.10+
    buf = Buffer.from(b64string, 'base64'); // Ta-da
} else {
    // older Node versions, now deprecated
    buf = new Buffer(b64string, 'base64'); // Ta-da
}

By default Sharepoint does not allow server-side code to be executed in ASPX files. See this for how to resolve that.

However, I would raise that having a code-behind is not necessarily difficult to deploy in Sharepoint (we do it extensively) - just compile your code-behind classes into an assembly and deploy it using a solution.

If still no, you can include all the code you'd normally place in a codebehind like so:

<script language="c#" runat="server">
public void Page_Load(object sender, EventArgs e)
{
  //hello, world!
}
</script>

Per @l3x, it depends.

There are clearly two sets of general situations where the correct answer can be different, along with a third which is not as general:

a) You are a user sending private mails:

Very few modern email systems implement case sensitivity, so you are probably fine to ignore case and choose whatever case you feel like using. There is no guarantee that all your mails will be delivered - but so few mails would be negatively affected that you should not worry about it.

b) You are developing mail software:

See RFC5321 2.4 excerpt at the bottom.

When you are developing mail software, you want to be RFC-compliant. You can make your own users' email addresses case insensitive if you want to (and you probably should). But in order to be RFC compliant, you MUST treat outside addresses as case sensitive.

c) Managing business-owned lists of email addresses as an employee:

It is possible that the same email recipient is added to a list more than once - but using different case. In this situation though the addresses are technically different, it might result in a recipient receiving duplicate emails. How you treat this situation is similar to situation a) in that you are probably fine to treat them as duplicates and to remove a duplicate entry. It is better to treat these as special cases however, by sending a "reminder" mail to both addresses to ask them if the case of the email address is accurate.

From a legal standpoint, if you remove a duplicate without acknowledgement/permission from both addresses, you can be held responsible for leaking private information/authentication to an unauthorised address simply because two actually-separate recipients have the same address with different cases.

Excerpt from RFC5321 2.4:

The local-part of a mailbox MUST BE treated as case sensitive. Therefore, SMTP implementations MUST take care to preserve the case of mailbox local-parts. In particular, for some hosts, the user "smith" is different from the user "Smith". However, exploiting the case sensitivity of mailbox local-parts impedes interoperability and is discouraged.

In general I would consider setting up of an environment variable (like PYTHONPATH) to be a bad practice. While this might be fine for a one off debugging but using this as
a regular practice might not be a good idea.

Usage of environment variable leads to situations like "it works for me" when some one
else reports problems in the code base. Also one might carry the same practice with the test environment as well, leading to situations like the tests running fine for a particular developer but probably failing when some one launches the tests.

For mac OS you should use this :

body {
 background: url(../../img/bg.png);
}

Use a regular expression to accomplish this.

function isAlphanumeric( str ) {
 return /^[0-9a-zA-Z]+$/.test(str);
}

int value, *ptr;

value = 8;
ptr = &value;
// ptr points to value, which lives on a stack frame.
// you are not responsible for managing its lifetime.

ptr = new int;
delete ptr;
// yes this is the normal way to manage the lifetime of
// dynamically allocated memory, you new'ed it, you delete it.

ptr = nullptr;
delete ptr;
// this is illogical, essentially you are saying delete nothing.

If you want to pass Method as parameter, use:

using System;

public void Method1()
{
    CallingMethod(CalledMethod);
}

public void CallingMethod(Action method)
{
    method();   // This will call the method that has been passed as parameter
}

public void CalledMethod()
{
    Console.WriteLine("This method is called by passing parameter");
}

    var statusHeight: CGFloat!
    if #available(iOS 13.0, *) {
         statusHeight = UIApplication.shared.keyWindow?.windowScene?.statusBarManager?.statusBarFrame.height
    } else {
        // Fallback on earlier versions
        statusHeight = UIApplication.shared.statusBarFrame.height
    }

There is a debugger keyword in JavaScript to debug the JavaScript code. Put debugger; snippet in your JavaScript code. It will automatically start debugging the JavaScript code at that point.

For example:

Suppose this is your test.js file

function func(){
    //Some stuff
    debugger;  //Debugging is automatically started from here
    //Some stuff
}
func();

• When the browser runs the web page in developer option with enabled debugger, then it automatically starts debugging from the debugger; point.
• There should be opened the developer window the browser.

Seven years later searches for vertical alignment still bring up this question, so I'll post another solution we have available to us now: flexbox positioning. Just set display:flex; justify-content: flex-end; flex-direction: column on the parent div (demonstrated in this fiddle as well):

#parentDiv
{
  display: flex;
  justify-content: flex-end;
  flex-direction: column;
  width:300px;
  height:300px;
  background-color:#ccc;
  background-repeat:repeat
}

This happens when a python extension (written in C) tries to access a memory beyond reach.

You can trace it in following ways.

• Add sys.settrace at the very first line of the code.

• Use gdb as described by Mark in this answer.. At the command prompt

  gdb python
  (gdb) run /path/to/script.py
  ## wait for segfault ##
  (gdb) backtrace
  ## stack trace of the c code
  

if [ $var1 != $var2 ] 
then 
echo "$var1"
else 
echo "$var2"
fi

ActiveRecord#where will return an ActiveRecord::Relation object (which will never be nil). Try using .empty? on the relation to test if it will return any records.

You haven't mentioned the Initial catalog name in the connection string. Give your database name as Initial Catalog name.

Welcome to the wonderful world of portability... or rather the lack of it. Before we start analyzing these two options in detail and take a deeper look how different operating systems handle them, it should be noted that the BSD socket implementation is the mother of all socket implementations. Basically all other systems copied the BSD socket implementation at some point in time (or at least its interfaces) and then started evolving it on their own. Of course the BSD socket implementation was evolved as well at the same time and thus systems that copied it later got features that were lacking in systems that copied it earlier. Understanding the BSD socket implementation is the key to understanding all other socket implementations, so you should read about it even if you don't care to ever write code for a BSD system.

There are a couple of basics you should know before we look at these two options. A TCP/UDP connection is identified by a tuple of five values:

{<protocol>, <src addr>, <src port>, <dest addr>, <dest port>}

Any unique combination of these values identifies a connection. As a result, no two connections can have the same five values, otherwise the system would not be able to distinguish these connections any longer.

The protocol of a socket is set when a socket is created with the socket() function. The source address and port are set with the bind() function. The destination address and port are set with the connect() function. Since UDP is a connectionless protocol, UDP sockets can be used without connecting them. Yet it is allowed to connect them and in some cases very advantageous for your code and general application design. In connectionless mode, UDP sockets that were not explicitly bound when data is sent over them for the first time are usually automatically bound by the system, as an unbound UDP socket cannot receive any (reply) data. Same is true for an unbound TCP socket, it is automatically bound before it will be connected.

If you explicitly bind a socket, it is possible to bind it to port 0, which means "any port". Since a socket cannot really be bound to all existing ports, the system will have to choose a specific port itself in that case (usually from a predefined, OS specific range of source ports). A similar wildcard exists for the source address, which can be "any address" (0.0.0.0 in case of IPv4 and :: in case of IPv6). Unlike in case of ports, a socket can really be bound to "any address" which means "all source IP addresses of all local interfaces". If the socket is connected later on, the system has to choose a specific source IP address, since a socket cannot be connected and at the same time be bound to any local IP address. Depending on the destination address and the content of the routing table, the system will pick an appropriate source address and replace the "any" binding with a binding to the chosen source IP address.

By default, no two sockets can be bound to the same combination of source address and source port. As long as the source port is different, the source address is actually irrelevant. Binding socketA to ipA:portA and socketB to ipB:portB is always possible if ipA != ipB holds true, even when portA == portB. E.g. socketA belongs to a FTP server program and is bound to 192.168.0.1:21 and socketB belongs to another FTP server program and is bound to 10.0.0.1:21, both bindings will succeed. Keep in mind, though, that a socket may be locally bound to "any address". If a socket is bound to 0.0.0.0:21, it is bound to all existing local addresses at the same time and in that case no other socket can be bound to port 21, regardless which specific IP address it tries to bind to, as 0.0.0.0 conflicts with all existing local IP addresses.

Anything said so far is pretty much equal for all major operating system. Things start to get OS specific when address reuse comes into play. We start with BSD, since as I said above, it is the mother of all socket implementations.

BSD

SO_REUSEADDR

If SO_REUSEADDR is enabled on a socket prior to binding it, the socket can be successfully bound unless there is a conflict with another socket bound to exactly the same combination of source address and port. Now you may wonder how is that any different than before? The keyword is "exactly". SO_REUSEADDR mainly changes the way how wildcard addresses ("any IP address") are treated when searching for conflicts.

Without SO_REUSEADDR, binding socketA to 0.0.0.0:21 and then binding socketB to 192.168.0.1:21 will fail (with error EADDRINUSE), since 0.0.0.0 means "any local IP address", thus all local IP addresses are considered in use by this socket and this includes 192.168.0.1, too. With SO_REUSEADDR it will succeed, since 0.0.0.0 and 192.168.0.1 are not exactly the same address, one is a wildcard for all local addresses and the other one is a very specific local address. Note that the statement above is true regardless in which order socketA and socketB are bound; without SO_REUSEADDR it will always fail, with SO_REUSEADDR it will always succeed.

To give you a better overview, let's make a table here and list all possible combinations:

SO_REUSEADDR       socketA        socketB       Result
---------------------------------------------------------------------
  ON/OFF       192.168.0.1:21   192.168.0.1:21    Error (EADDRINUSE)
  ON/OFF       192.168.0.1:21      10.0.0.1:21    OK
  ON/OFF          10.0.0.1:21   192.168.0.1:21    OK
   OFF             0.0.0.0:21   192.168.1.0:21    Error (EADDRINUSE)
   OFF         192.168.1.0:21       0.0.0.0:21    Error (EADDRINUSE)
   ON              0.0.0.0:21   192.168.1.0:21    OK
   ON          192.168.1.0:21       0.0.0.0:21    OK
  ON/OFF           0.0.0.0:21       0.0.0.0:21    Error (EADDRINUSE)

The table above assumes that socketA has already been successfully bound to the address given for socketA, then socketB is created, either gets SO_REUSEADDR set or not, and finally is bound to the address given for socketB. Result is the result of the bind operation for socketB. If the first column says ON/OFF, the value of SO_REUSEADDR is irrelevant to the result.

Okay, SO_REUSEADDR has an effect on wildcard addresses, good to know. Yet that isn't it's only effect it has. There is another well known effect which is also the reason why most people use SO_REUSEADDR in server programs in the first place. For the other important use of this option we have to take a deeper look on how the TCP protocol works.

A socket has a send buffer and if a call to the send() function succeeds, it does not mean that the requested data has actually really been sent out, it only means the data has been added to the send buffer. For UDP sockets, the data is usually sent pretty soon, if not immediately, but for TCP sockets, there can be a relatively long delay between adding data to the send buffer and having the TCP implementation really send that data. As a result, when you close a TCP socket, there may still be pending data in the send buffer, which has not been sent yet but your code considers it as sent, since the send() call succeeded. If the TCP implementation was closing the socket immediately on your request, all of this data would be lost and your code wouldn't even know about that. TCP is said to be a reliable protocol and losing data just like that is not very reliable. That's why a socket that still has data to send will go into a state called TIME_WAIT when you close it. In that state it will wait until all pending data has been successfully sent or until a timeout is hit, in which case the socket is closed forcefully.

At most, the amount of time the kernel will wait before it closes the socket, regardless if it still has data in flight or not, is called the Linger Time. The Linger Time is globally configurable on most systems and by default rather long (two minutes is a common value you will find on many systems). It is also configurable per socket using the socket option SO_LINGER which can be used to make the timeout shorter or longer, and even to disable it completely. Disabling it completely is a very bad idea, though, since closing a TCP socket gracefully is a slightly complex process and involves sending forth and back a couple of packets (as well as resending those packets in case they got lost) and this whole close process is also limited by the Linger Time. If you disable lingering, your socket may not only lose data in flight, it is also always closed forcefully instead of gracefully, which is usually not recommended. The details about how a TCP connection is closed gracefully are beyond the scope of this answer, if you want to learn more about, I recommend you have a look at this page. And even if you disabled lingering with SO_LINGER, if your process dies without explicitly closing the socket, BSD (and possibly other systems) will linger nonetheless, ignoring what you have configured. This will happen for example if your code just calls exit() (pretty common for tiny, simple server programs) or the process is killed by a signal (which includes the possibility that it simply crashes because of an illegal memory access). So there is nothing you can do to make sure a socket will never linger under all circumstances.

The question is, how does the system treat a socket in state TIME_WAIT? If SO_REUSEADDR is not set, a socket in state TIME_WAIT is considered to still be bound to the source address and port and any attempt to bind a new socket to the same address and port will fail until the socket has really been closed, which may take as long as the configured Linger Time. So don't expect that you can rebind the source address of a socket immediately after closing it. In most cases this will fail. However, if SO_REUSEADDR is set for the socket you are trying to bind, another socket bound to the same address and port in state TIME_WAIT is simply ignored, after all its already "half dead", and your socket can bind to exactly the same address without any problem. In that case it plays no role that the other socket may have exactly the same address and port. Note that binding a socket to exactly the same address and port as a dying socket in TIME_WAIT state can have unexpected, and usually undesired, side effects in case the other socket is still "at work", but that is beyond the scope of this answer and fortunately those side effects are rather rare in practice.

There is one final thing you should know about SO_REUSEADDR. Everything written above will work as long as the socket you want to bind to has address reuse enabled. It is not necessary that the other socket, the one which is already bound or is in a TIME_WAIT state, also had this flag set when it was bound. The code that decides if the bind will succeed or fail only inspects the SO_REUSEADDR flag of the socket fed into the bind() call, for all other sockets inspected, this flag is not even looked at.

SO_REUSEPORT

SO_REUSEPORT is what most people would expect SO_REUSEADDR to be. Basically, SO_REUSEPORT allows you to bind an arbitrary number of sockets to exactly the same source address and port as long as all prior bound sockets also had SO_REUSEPORT set before they were bound. If the first socket that is bound to an address and port does not have SO_REUSEPORT set, no other socket can be bound to exactly the same address and port, regardless if this other socket has SO_REUSEPORT set or not, until the first socket releases its binding again. Unlike in case of SO_REUESADDR the code handling SO_REUSEPORT will not only verify that the currently bound socket has SO_REUSEPORT set but it will also verify that the socket with a conflicting address and port had SO_REUSEPORT set when it was bound.

SO_REUSEPORT does not imply SO_REUSEADDR. This means if a socket did not have SO_REUSEPORT set when it was bound and another socket has SO_REUSEPORT set when it is bound to exactly the same address and port, the bind fails, which is expected, but it also fails if the other socket is already dying and is in TIME_WAIT state. To be able to bind a socket to the same addresses and port as another socket in TIME_WAIT state requires either SO_REUSEADDR to be set on that socket or SO_REUSEPORT must have been set on both sockets prior to binding them. Of course it is allowed to set both, SO_REUSEPORT and SO_REUSEADDR, on a socket.

There is not much more to say about SO_REUSEPORT other than that it was added later than SO_REUSEADDR, that's why you will not find it in many socket implementations of other systems, which "forked" the BSD code before this option was added, and that there was no way to bind two sockets to exactly the same socket address in BSD prior to this option.

Connect() Returning EADDRINUSE?

Most people know that bind() may fail with the error EADDRINUSE, however, when you start playing around with address reuse, you may run into the strange situation that connect() fails with that error as well. How can this be? How can a remote address, after all that's what connect adds to a socket, be already in use? Connecting multiple sockets to exactly the same remote address has never been a problem before, so what's going wrong here?

As I said on the very top of my reply, a connection is defined by a tuple of five values, remember? And I also said, that these five values must be unique otherwise the system cannot distinguish two connections any longer, right? Well, with address reuse, you can bind two sockets of the same protocol to the same source address and port. That means three of those five values are already the same for these two sockets. If you now try to connect both of these sockets also to the same destination address and port, you would create two connected sockets, whose tuples are absolutely identical. This cannot work, at least not for TCP connections (UDP connections are no real connections anyway). If data arrived for either one of the two connections, the system could not tell which connection the data belongs to. At least the destination address or destination port must be different for either connection, so that the system has no problem to identify to which connection incoming data belongs to.

So if you bind two sockets of the same protocol to the same source address and port and try to connect them both to the same destination address and port, connect() will actually fail with the error EADDRINUSE for the second socket you try to connect, which means that a socket with an identical tuple of five values is already connected.

Multicast Addresses

Most people ignore the fact that multicast addresses exist, but they do exist. While unicast addresses are used for one-to-one communication, multicast addresses are used for one-to-many communication. Most people got aware of multicast addresses when they learned about IPv6 but multicast addresses also existed in IPv4, even though this feature was never widely used on the public Internet.

The meaning of SO_REUSEADDR changes for multicast addresses as it allows multiple sockets to be bound to exactly the same combination of source multicast address and port. In other words, for multicast addresses SO_REUSEADDR behaves exactly as SO_REUSEPORT for unicast addresses. Actually, the code treats SO_REUSEADDR and SO_REUSEPORT identically for multicast addresses, that means you could say that SO_REUSEADDR implies SO_REUSEPORT for all multicast addresses and the other way round.

FreeBSD/OpenBSD/NetBSD

All these are rather late forks of the original BSD code, that's why they all three offer the same options as BSD and they also behave the same way as in BSD.

macOS (MacOS X)

At its core, macOS is simply a BSD-style UNIX named "Darwin", based on a rather late fork of the BSD code (BSD 4.3), which was then later on even re-synchronized with the (at that time current) FreeBSD 5 code base for the Mac OS 10.3 release, so that Apple could gain full POSIX compliance (macOS is POSIX certified). Despite having a microkernel at its core ("Mach"), the rest of the kernel ("XNU") is basically just a BSD kernel, and that's why macOS offers the same options as BSD and they also behave the same way as in BSD.

iOS / watchOS / tvOS

iOS is just a macOS fork with a slightly modified and trimmed kernel, somewhat stripped down user space toolset and a slightly different default framework set. watchOS and tvOS are iOS forks, that are stripped down even further (especially watchOS). To my best knowledge they all behave exactly as macOS does.

Linux

Linux < 3.9

Prior to Linux 3.9, only the option SO_REUSEADDR existed. This option behaves generally the same as in BSD with two important exceptions:

1. As long as a listening (server) TCP socket is bound to a specific port, the SO_REUSEADDR option is entirely ignored for all sockets targeting that port. Binding a second socket to the same port is only possible if it was also possible in BSD without having SO_REUSEADDR set. E.g. you cannot bind to a wildcard address and then to a more specific one or the other way round, both is possible in BSD if you set SO_REUSEADDR. What you can do is you can bind to the same port and two different non-wildcard addresses, as that's always allowed. In this aspect Linux is more restrictive than BSD.

2. The second exception is that for client sockets, this option behaves exactly like SO_REUSEPORT in BSD, as long as both had this flag set before they were bound. The reason for allowing that was simply that it is important to be able to bind multiple sockets to exactly to the same UDP socket address for various protocols and as there used to be no SO_REUSEPORT prior to 3.9, the behavior of SO_REUSEADDR was altered accordingly to fill that gap. In that aspect Linux is less restrictive than BSD.

Linux >= 3.9

Linux 3.9 added the option SO_REUSEPORT to Linux as well. This option behaves exactly like the option in BSD and allows binding to exactly the same address and port number as long as all sockets have this option set prior to binding them.

Yet, there are still two differences to SO_REUSEPORT on other systems:

1. To prevent "port hijacking", there is one special limitation: All sockets that want to share the same address and port combination must belong to processes that share the same effective user ID! So one user cannot "steal" ports of another user. This is some special magic to somewhat compensate for the missing SO_EXCLBIND/SO_EXCLUSIVEADDRUSE flags.

2. Additionally the kernel performs some "special magic" for SO_REUSEPORT sockets that isn't found in other operating systems: For UDP sockets, it tries to distribute datagrams evenly, for TCP listening sockets, it tries to distribute incoming connect requests (those accepted by calling accept()) evenly across all the sockets that share the same address and port combination. Thus an application can easily open the same port in multiple child processes and then use SO_REUSEPORT to get a very inexpensive load balancing.

Android

Even though the whole Android system is somewhat different from most Linux distributions, at its core works a slightly modified Linux kernel, thus everything that applies to Linux should apply to Android as well.

Windows

Windows only knows the SO_REUSEADDR option, there is no SO_REUSEPORT. Setting SO_REUSEADDR on a socket in Windows behaves like setting SO_REUSEPORT and SO_REUSEADDR on a socket in BSD, with one exception:

Prior to Windows 2003, a socket with SO_REUSEADDR could always been bound to exactly the same source address and port as an already bound socket, even if the other socket did not have this option set when it was bound. This behavior allowed an application "to steal" the connected port of another application. Needless to say that this has major security implications!

Microsoft realized that and added another important socket option: SO_EXCLUSIVEADDRUSE. Setting SO_EXCLUSIVEADDRUSE on a socket makes sure that if the binding succeeds, the combination of source address and port is owned exclusively by this socket and no other socket can bind to them, not even if it has SO_REUSEADDR set.

This default behavior was changed first in Windows 2003, Microsoft calls that "Enhanced Socket Security" (funny name for a behavior that is default on all other major operating systems). For more details just visit this page. There are three tables: The first one shows the classic behavior (still in use when using compatibility modes!), the second one shows the behavior of Windows 2003 and up when the bind() calls are made by the same user, and the third one when the bind() calls are made by different users.

Solaris

Solaris is the successor of SunOS. SunOS was originally based on a fork of BSD, SunOS 5 and later was based on a fork of SVR4, however SVR4 is a merge of BSD, System V, and Xenix, so up to some degree Solaris is also a BSD fork, and a rather early one. As a result Solaris only knows SO_REUSEADDR, there is no SO_REUSEPORT. The SO_REUSEADDR behaves pretty much the same as it does in BSD. As far as I know there is no way to get the same behavior as SO_REUSEPORT in Solaris, that means it is not possible to bind two sockets to exactly the same address and port.

Similar to Windows, Solaris has an option to give a socket an exclusive binding. This option is named SO_EXCLBIND. If this option is set on a socket prior to binding it, setting SO_REUSEADDR on another socket has no effect if the two sockets are tested for an address conflict. E.g. if socketA is bound to a wildcard address and socketB has SO_REUSEADDR enabled and is bound to a non-wildcard address and the same port as socketA, this bind will normally succeed, unless socketA had SO_EXCLBIND enabled, in which case it will fail regardless the SO_REUSEADDR flag of socketB.

Other Systems

In case your system is not listed above, I wrote a little test program that you can use to find out how your system handles these two options. Also if you think my results are wrong, please first run that program before posting any comments and possibly making false claims.

All that the code requires to build is a bit POSIX API (for the network parts) and a C99 compiler (actually most non-C99 compiler will work as well as long as they offer inttypes.h and stdbool.h; e.g. gcc supported both long before offering full C99 support).

All that the program needs to run is that at least one interface in your system (other than the local interface) has an IP address assigned and that a default route is set which uses that interface. The program will gather that IP address and use it as the second "specific address".

It tests all possible combinations you can think of:

• TCP and UDP protocol
• Normal sockets, listen (server) sockets, multicast sockets
• SO_REUSEADDR set on socket1, socket2, or both sockets
• SO_REUSEPORT set on socket1, socket2, or both sockets
• All address combinations you can make out of 0.0.0.0 (wildcard), 127.0.0.1 (specific address), and the second specific address found at your primary interface (for multicast it's just 224.1.2.3 in all tests)

and prints the results in a nice table. It will also work on systems that don't know SO_REUSEPORT, in which case this option is simply not tested.

What the program cannot easily test is how SO_REUSEADDR acts on sockets in TIME_WAIT state as it's very tricky to force and keep a socket in that state. Fortunately most operating systems seems to simply behave like BSD here and most of the time programmers can simply ignore the existence of that state.

Here's the code (I cannot include it here, answers have a size limit and the code would push this reply over the limit).

The above answer is useful but in graphs, it is difficult to distinguish between darker gradients of black. One alternative I found is to use gradients of gray colors as follows

palette(gray.colors(10, 0.9, 0.4))
plot(rep(1,10),col=1:10,pch=19,cex=3))

More info on gray scale here.

Added

When I used the code above for different colours like blue and black, the gradients were not that clear. heat.colors() seems more useful.

The question was posted long time ago, many answers pool the target periodically and produces unnecessary waste of resources if the target is unchanged. In addition, most answers do not block the program while waiting for changes as required by the original post.

We can now apply a solution that is purely event-driven.

The solution uses onClick event to deliver event triggered by value change.

The solution can be run on modern browsers that support Promise and async/await. If you are using Node.js, consider EventEmitter as a better solution.

The answer given by Jeff Paulsen is correct but the Comprarer can be much simplified to this:

public class SemiNumericComparer: IComparer<string>
{
    public int Compare(string s1, string s2)
    {
        if (IsNumeric(s1) && IsNumeric(s2))
          return Convert.ToInt32(s1) - Convert.ToInt32(s2)

        if (IsNumeric(s1) && !IsNumeric(s2))
            return -1;

        if (!IsNumeric(s1) && IsNumeric(s2))
            return 1;

        return string.Compare(s1, s2, true);
    }

    public static bool IsNumeric(object value)
    {
        int result;
        return Int32.TryParse(value, out result);
    }
}

This works because the only thing that is checked for the result of the Comparer is if the result is larger, smaller or equal to zero. One can simply subtract the values from another and does not have to handle the return values.

Also the IsNumeric method should not have to use a try-block and can benefit from TryParse.

And for those who are not sure: This Comparer will sort values so, that non numeric values are always appended to the end of the list. If one wants them at the beginning the second and third if block have to be swapped.

From GitHub:

The blame command is a Git feature, designed to help you determine who made changes to a file.

Despite its negative-sounding name, git blame is actually pretty innocuous; its primary function is to point out who changed which lines in a file, and why. It can be a useful tool to identify changes in your code.

Basically, git-blame is used to show what revision and author last modified each line of a file. It's like checking the history of the development of a file.

HEAD is not the latest revision, it's the current revision. Usually, it's the latest revision of the current branch, but it doesn't have to be.

master is a name commonly given to the main branch, but it could be called anything else (or there could be no main branch).

origin is a name commonly given to the main remote. remote is another repository that you can pull from and push to. Usually it's on some server, like github.

This can happen when:

• You have multiple copies of the Android SDK installed on your machine. You may be updating the available images and devices for one copy of the Android SDK, and trying to debug or run your application in another.

  If you're using Eclipse, take a look at your "Preferences | Android | SDK Location". Make sure it's the path you expect. If not, change the path to point to where you think the Android SDK is installed.

• You don't have an Android device setup in your emulator as detailed in other answers on this page.

Your $_POST array contains the invite array, so reading it out as

<?php
if(isset($_POST['invite'])){
  $invite = $_POST['invite'];
  echo $invite;
}
?>

won't work since it's an array. You have to loop through the array to get all of the values.

<?php
if(isset($_POST['invite'])){
  if (is_array($_POST['invite'])) {
    foreach($_POST['invite'] as $value){
      echo $value;
    }
  } else {
    $value = $_POST['invite'];
    echo $value;
  }
}
?>

Another way: The Iterator has an optional remove()-method, that is implemented for ArrayList. You can use it while iterating.

I don't know though, which variant is the most performant, you should measure it.

starblue commented, that the complexity isn't good, and that's true (for removeAll() too), because ArrayList has to copy all elements, if in the middle is an element added or removed. For that cases should a LinkedList work better. But, as we all don't know your real use-cases the best is too measure all variants, to pick the best solution.

I added PM2_HOME environment variable on a system level and now it works alright.

To use $variables inside your calc() of the height property:

HTML:

<div></div>

SCSS:

$a: 4em;

div {
  height: calc(#{$a} + 7px);
  background: #e53b2c;
}

What you are trying to do is add additional information to each item in the list that you already created so

    alist[ 'from form', 'stuff 2', 'stuff 3']

    for j in range( 0,len[alist]):
        temp= []
        temp.append(alist[j]) # alist[0] is 'from form' 
        temp.append('t') # slot for first piece of data 't'
        temp.append('-') # slot for second piece of data

    blist.append(temp)      # will be alist with 2 additional fields for extra stuff assocated with each item in alist  

function getURLParameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;
}

So you can use:

myvar = getURLParameter('myvar');

Just use negative margins, in the second div say:

<div style="margin-top: -25px;">

And make sure to set the z-index property to get the layering you want.

This works:

$output = $array1 + $array2;

I was using a .Net Core 2.1 API with the [FromBody] attribute and I had to use the following solution to successfully Post to it:

_apiClient =  new HttpClient();
_apiClient.BaseAddress = new Uri(<YOUR API>);
var MyObject myObject = new MyObject(){
    FirstName = "Me",
    LastName = "Myself"
};

var stringified = JsonConvert.SerializeObject(myObject);
var result = await _apiClient.PostAsync("api/appusers", new StringContent(stringified, Encoding.UTF8, "application/json"));

It doesn't print anything. It is used to figure out how many characters got printed before %n appeared in the format string, and output that to the provided int:

#include <stdio.h>

int main(int argc, char* argv[])
{
    int resultOfNSpecifier = 0;
    _set_printf_count_output(1); /* Required in visual studio */
    printf("Some format string%n\n", &resultOfNSpecifier);
    printf("Count of chars before the %%n: %d\n", resultOfNSpecifier);
    return 0;
}

From C# 2.0:

You need to understand the different between pass-by-reference and pass-by-value.

Basically, C only support pass-by-value. So you can't reference a variable directly when pass it to a function. If you want to change the variable out a function, which the swap do, you need to use pass-by-reference. To implement pass-by-reference in C, need to use pointer, which can dereference to the value.

The function:

void intSwap(int* a, int* b)

It pass two pointers value to intSwap, and in the function, you swap the values which a/b pointed to, but not the pointer itself. That's why R. Martinho & Dan Fego said it swap two integers, not pointers.

For chars, I think you mean string, are more complicate. String in C is implement as a chars array, which referenced by a char*, a pointer, as the string value. And if you want to pass a char* by pass-by-reference, you need to use the ponter of char*, so you get char**.

Maybe the code below more clearly:

typedef char* str;
void strSwap(str* a, str* b);

The syntax swap(int& a, int& b) is C++, which mean pass-by-reference directly. Maybe some C compiler implement too.

Hope I make it more clearly, not comfuse.

In order to give a value in the table, we need to give a command:

php artisan make:migration create_users_table

and after then this command line

php artisan migrate

......

My specific case has the following scenario. Our tests

public class VenueResourceContainerTest extends BaseTixContainerTest

all extend

BaseTixContainerTest

and JUnit was trying to run BaseTixContainerTest. Poor BaseTixContainerTest was just trying to setup the container, setup the client, order some pizza and relax... man.

As mentioned previously, you can annotate the class with

@Ignore

But that caused JUnit to report that test as skipped (as opposed to completely ignored).

Tests run: 4, Failures: 0, Errors: 0, Skipped: 1

That kind of irritated me.

So I made BaseTixContainerTest abstract, and now JUnit truly ignores it.

Tests run: 3, Failures: 0, Errors: 0, Skipped: 0

This should give you the commands printed out in separate lines:

import readline
map(lambda p:print(readline.get_history_item(p)),
    map(lambda p:p, range(readline.get_current_history_length()))
)

Here is what you can do. Though there are lot many ways to achieve it.

DateTime? d = null;    
if (txtBirthDate.Text == string.Empty)
    objinfo.BirthDate = d;
else
    objinfo.BirthDate =  DateTime.Parse(txtBirthDate.Text);

Note: This will work only if your database datetime column is Allow Null. Else you can define a standard minimum value for DateTime d.

Just an update because I was trying it on Windows 10 you do need to set the path to the following: ;C:\Program Files\PostgreSQL\9.5\bin ;C:\Program Files\PostgreSQL\9.5\lib

You can do that either through the CMD by using set PATH [the path] or from my

computer => properties => advanced system settings=> Environment Variables => System Variables

Then search for path.

Important: don't replace the PATHs that are already there just add one beside them as follows ;C:\Program Files\PostgreSQL\9.5\bin ;C:\Program Files\PostgreSQL\9.5\lib

Please note: On windows 10, if you follow this: computer => properties => advanced system settings=> Environment Variables => System Variables> select PATH, you actually get the option to add new row. Click Edit, add the /bin and /lib folder locations and save changes.

Then close your command prompt if it's open and then start it again try psql --version If it gives you an answer then you are good to go if not try echo %PATH% and see if the path you set was added or not and if it's added is it added correctly or not.

"UPDATE member_profile SET points = points + 1 WHERE user_id = '".$userid."'"

For Windows 7: c:\users\all users\MySql\MySql Server x.x\Data\

Where x.x is the version number of the sql server installed in your machine.

Yes, a class is what you need. An class defines an own type.

Both your code are correct, but I prefer the second one, as comparing a boolean to true or false is redundant.

For better readibility, you can also use the not operator:

<c:if test="${not theBooleanVariable}">It's false!</c:if>

Almost by definition, the client-side JavaScript is not at the receiving end of a http request, so it has no headers to read. Most commonly, your JavaScript is the result of an http response. If you are trying to get the values of the http request that generated your response, you'll have to write server side code to embed those values in the JavaScript you produce.

It gets a little tricky to have server-side code generate client side code, so be sure that is what you need. For instance, if you want the User-agent information, you might find it sufficient to get the various values that JavaScript provides for browser detection. Start with navigator.appName and navigator.appVersion.

The following code uses both data.table and fastmatch for increased speed.

library("data.table")
library("fastmatch")

a1 <- setDT(data.frame(a = 1:5, b=letters[1:5]))
a2 <- setDT(data.frame(a = 1:3, b=letters[1:3]))

compare_rows <- a1$a %fin% a2$a
# the %fin% function comes from the `fastmatch` package

added_rows <- a1[which(compare_rows == FALSE)]

added_rows

#    a b
# 1: 4 d
# 2: 5 e

You should declare toString() and valueOf() method in enum.

 import java.io.Serializable;

public enum Gesture implements Serializable {
    ROCK,PAPER,SCISSORS;

    public String toString(){
        switch(this){
        case ROCK :
            return "Rock";
        case PAPER :
            return "Paper";
        case SCISSORS :
            return "Scissors";
        }
        return null;
    }

    public static Gesture valueOf(Class<Gesture> enumType, String value){
        if(value.equalsIgnoreCase(ROCK.toString()))
            return Gesture.ROCK;
        else if(value.equalsIgnoreCase(PAPER.toString()))
            return Gesture.PAPER;
        else if(value.equalsIgnoreCase(SCISSORS.toString()))
            return Gesture.SCISSORS;
        else
            return null;
    }
}

2019 update

As pointed out by others in related questions (see here, here, here, here, here, here, and here), you can now unstage a file with git restore --staged <file>.

To unstage all the files in your project, run the following from the root of the repository (the command is recursive):

git restore --staged .

If you only want to unstage the files in a directory, navigate to it before running the above or run:

git restore --staged <directory-path>

Notes

• git restore was introduced in July 2019 and released in version 2.23.
  With the --staged flag, it restores the content of the working tree from HEAD (so it does the opposite of git add and does not delete any change).

• This is a new command, but the behaviour of the old commands remains unchanged. So the older answers with git reset or git reset HEAD are still perfectly valid.

• When running git status with staged uncommitted file(s), this is now what Git suggests to use to unstage file(s) (instead of git reset HEAD <file> as it used to prior to v2.23).

try this

   SELECT group_name, employees, surveys, COUNT( surveys ) AS test1, 
        concat(round(( surveys/employees * 100 ),2),'%') AS percentage
    FROM a_test
    GROUP BY employees

Often our databases are really big and the take time to take dump directly from remote machine to other machine as our friends other have suggested above.

In such cases what you can do is to take the dump on remote machine using MYSQLDUMP Command

MYSQLDUMP -uuser -p --all-databases > file_name.sql

and than transfer that file from remote server to your machine using Linux SCP Command

scp user@remote_ip:~/mysql_dump_file_name.sql ./

I was also suffering from the same issue. Finally I resolved it by setting binary value in capabilites as shown below. At run time it uses this value so it is must to set.

DesiredCapabilities capability = DesiredCapabilities.firefox();
capability.setCapability("platform", Platform.ANY);
capability.setCapability("binary", "/ms/dist/fsf/PROJ/firefox/16.0.0/bin/firefox"); //for linux

//capability.setCapability("binary", "C:\\Program Files\\Mozilla  Firefox\\msfirefox.exe"); //for windows                
WebDriver    currentDriver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capability);

And you are done!!! Happy coding :)

I had what at first seemed to be an identical problem, but it turned out to be due to an NHibernate/WPF compatibility issue. The problem was caused by the way WPF checks for object equality. I was able to get my stuff to work by using the object ID property in the SelectedValue and SelectedValuePath properties.

<ComboBox Name="CategoryList"
          DisplayMemberPath="CategoryName"
          SelectedItem="{Binding Path=CategoryParent}"
          SelectedValue="{Binding Path=CategoryParent.ID}"
          SelectedValuePath="ID">

See the blog post from Chester, The WPF ComboBox - SelectedItem, SelectedValue, and SelectedValuePath with NHibernate, for details.

Here, we can do this way as well:

//category [@name='category name']/author[contains(text(),'authorname')]

OR

//category [@name='category name']//author[contains(text(),'authorname')]

if(isnull({uspRptMonthlyGasRevenueByGas;1.YearTotal})) = true then
   "nd"
else
    totext({uspRptMonthlyGasRevenueByGas;1.YearTotal},'###.00')

The above logic should be what you are looking for.

f = urllib2.urlopen(target_url)

I myself landed on these answers last day, trying to find a way to deep copy complex structures, which may include recursive links. As I wasn't satisfied with anything being suggested before, I implemented this wheel myself. And it works quite well. Hope it helps someone.

Example usage:

OriginalStruct.deep_copy = deep_copy; // attach the function as a method

TheClone = OriginalStruct.deep_copy();

Please look at https://github.com/latitov/JS_DeepCopy for live examples how to use it, and also deep_print() is there.

If you need it quick, right here's the source of deep_copy() function:

function deep_copy() {
    'use strict';   // required for undef test of 'this' below

    // Copyright (c) 2019, Leonid Titov, Mentions Highly Appreciated.

    var id_cnt = 1;
    var all_old_objects = {};
    var all_new_objects = {};
    var root_obj = this;

    if (root_obj === undefined) {
        console.log(`deep_copy() error: wrong call context`);
        return;
    }

    var new_obj = copy_obj(root_obj);

    for (var id in all_old_objects) {
        delete all_old_objects[id].__temp_id;
    }

    return new_obj;
    //

    function copy_obj(o) {
        var new_obj = {};
        if (o.__temp_id === undefined) {
            o.__temp_id = id_cnt;
            all_old_objects[id_cnt] = o;
            all_new_objects[id_cnt] = new_obj;
            id_cnt ++;

            for (var prop in o) {
                if (o[prop] instanceof Array) {
                    new_obj[prop] = copy_array(o[prop]);
                }
                else if (o[prop] instanceof Object) {
                    new_obj[prop] = copy_obj(o[prop]);
                }
                else if (prop === '__temp_id') {
                    continue;
                }
                else {
                    new_obj[prop] = o[prop];
                }
            }
        }
        else {
            new_obj = all_new_objects[o.__temp_id];
        }
        return new_obj;
    }
    function copy_array(a) {
        var new_array = [];
        if (a.__temp_id === undefined) {
            a.__temp_id = id_cnt;
            all_old_objects[id_cnt] = a;
            all_new_objects[id_cnt] = new_array;
            id_cnt ++;

            a.forEach((v,i) => {
                if (v instanceof Array) {
                    new_array[i] = copy_array(v);
                }
                else if (v instanceof Object) {
                    new_array[i] = copy_object(v);
                }
                else {
                    new_array[i] = v;
                }
            });
        }
        else {
            new_array = all_new_objects[a.__temp_id];
        }
        return new_array;
    }
}

Cheers@!

we can groupby the 'name' and 'month' columns, then call agg() functions of Panda’s DataFrame objects.

The aggregation functionality provided by the agg() function allows multiple statistics to be calculated per group in one calculation.

df.groupby(['name', 'month'], as_index = False).agg({'text': ' '.join})

there's socket.settimeout()

The answers over allow leading zeros in Ip address, and that it is not correct. For example ("123.045.067.089"should return false).

The correct way to do it like that.

 function isValidIP(ipaddress) {  
if (/^(25[0-5]|2[0-4][0-9]|[1]?[1-9][1-9]?)\.(25[0-5]|2[0-4][0-9]|[1]?[1-9][1-9]?)\.(25[0-5]|2[0-4][0-9]|[1]?[1-9][1-9]?)\.(25[0-5]|2[0-4][0-9]|[1]?[1-9][1-9]?)$/.test(ipaddress)) {  
  return (true)  
}   
return (false) } 

This function will not allow zero to lead IP addresses.

Simple working camera app avoiding the null intent problem

- all changed code included in this reply; close to android tutorial

I've been spending plenty of time on this issue, so I decided to create an account and share my outcomes with you.

The official android tutorial "Taking Photos Simply" turned out to not quite hold what it promised. The code provided there did not work on my device: a Samsung Galaxy S4 Mini GT-I9195 running android version 4.4.2 / KitKat / API Level 19.

I figured out that the main problem was the following line in the method invoked when capturing the photo (dispatchTakePictureIntent in the tutorial):

takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);

It resulted in the intent subsequently catched by onActivityResult being null.

To solve this problem, I pulled much inspiration out of earlier replies here and some helpful posts on github (mostly this one by deepwinter - big thanks to him; you might want to check out his reply on a closely related post as well).

Following these pleasant pieces of advice, I chose the strategy of deleting the mentioned putExtra line and doing the corresponding thing of getting back the taken picture from the camera within the onActivityResult() method instead. The decisive lines of code to get back the bitmap associated with the picture are:

        Uri uri = intent.getData();
        Bitmap bitmap = null;
        try {
            bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), uri);
        } catch (IOException e) {
            e.printStackTrace();
        }

I created an exemplary app which just has the ability to take a picture, save it on the SD card and display it. I think this might be helpful to people in the same situation as me when I stumbled on this issue, since the current help suggestions mostly refer to rather extensive github posts which do the thing in question but aren't too easy to oversee for newbies like me. With respect to the file system Android Studio creates per default when creating a new project, I just had to change three files for my purpose:

activity_main.xml :

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

    android:layout_height="wrap_content"
    android:onClick="takePicAndDisplayIt"
    android:text="Take a pic and display it." />

<ImageView
    android:id="@+id/image1"
    android:layout_width="match_parent"
    android:layout_height="200dp" />

</LinearLayout>

// copied from the android development pages; just added a Toast to show the storage location
private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmm").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  /* prefix */

        File file = null;
        try {
            file = createImageFile();
        } catch (IOException ex) {
            // Error occurred while creating the File
        }

        startActivityForResult(intent, REQUEST_TAKE_PHOTO);
    }

        image.setImageBitmap(bitmap);
    }
}
}

AndroidManifest.xml :

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


<!--only added paragraph-->
<uses-feature
    android:name="android.hardware.camera"
    android:required="true" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />  <!-- only crucial line to add; for me it still worked without the other lines in this paragraph -->
<uses-permission android:name="android.permission.CAMERA" />


<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"

    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>
</application>

</manifest>

Note that the solution I found for the problem also led to a simplification of the android manifest file: the changes suggested by the android tutorial in terms of adding a provider are no longer needed since I am not making use of any in my java code. Hence, only few standard lines -mostly regarding permissions- had to be added to the manifest file.

It might additionally be valuable to point out that Android Studio's autoimport may not be capable of handling java.text.SimpleDateFormat and java.util.Date. I had to import both of them manually.

I use the following code on http://www.diagnomics.com/

Smooth transition from b/w to color with magnifying effect (scale)

    img.color_flip {
      filter: url(filters.svg#grayscale); /* Firefox 3.5+ */
      filter: gray; /* IE5+ */
      -webkit-filter: grayscale(1); /* Webkit Nightlies & Chrome Canary */
      -webkit-transition: all .5s ease-in-out;
    }

    img.color_flip:hover {
      filter: none;
      -webkit-filter: grayscale(0);
      -webkit-transform: scale(1.1);
    }

I wouldn't bother looking for ASP.NET stuff specifically (probably won't find any anyways). Finding a good CSS theme easily can be used in ASP.NET.

Here's some sites that I love for CSS goodness:

http://www.oswd.org/
http://www.openwebdesign.org/
http://www.styleshout.com/
http://www.freelayouts.com/

In my case i had the error sdk location not found

What i did: I went to the cloned project from git opened the project directory opened the app directory inside the project copied the local.properties file and then pasted it in the project directory Then it worked

Don't forget to refresh servers through :

Facebook Debugger

And click on "Collect new info"

I don't have much experience than above users but I faced this same issue and I Solved this with below Solution

<Button
        android:id="@+id/btnRemove"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/btnEdit"
        android:layout_weight="1"
        android:background="@drawable/btn"
        android:text="@string/remove" 
        android:onClick="btnRemoveClick"
        />

btnRemoveClick Click event

public void btnRemoveClick(View v)
{
    final int position = listviewItem.getPositionForView((View) v.getParent()); 
    listItem.remove(position);
    ItemAdapter.notifyDataSetChanged();

}

I found this article and tried the tutorial. Basically, you can use the date constructor to parse a date, then write get the seconds from the getTime() method

var d=new Date("October 13, 1975 11:13:00");
document.write(d.getTime() + " milliseconds since 1970/01/01");

Does this work?

Google "select item selenium webdriver" brings up How do I set an option as selected using Selenium WebDriver (selenium 2.0) client in ruby as first result. This is not Java, but you should be able to translate it without too much work. https://sqa.stackexchange.com/questions/1355/what-is-the-correct-way-to-select-an-option-using-seleniums-python-webdriver is in the top 5, again not Java but the API is very similar.

You need to specify the encoding of the InputStreamReader using the Charset parameter.

Charset inputCharset = Charset.forName("ISO-8859-1");
InputStreamReader isr = new InputStreamReader(fis, inputCharset));

This is work for me. i hope to help you.

Make sure that you have made the content-type as application/json in header request and Post from body under the raw tab.

{
  "address": "colombo",
  "username": "hesh",
  "password": "123",
  "registetedDate": "2015-4-3",
  "firstname": "hesh",
  "contactNo": "07762",
  "accountNo": "16161",
  "lastName": "jay",
  "arrayObjectName" : [{
    "Id" : 1,
    "Name": "ABC" },
    {
    "Id" : 2,
    "Name" : "XYZ"
  }],
  "intArrayName" : [111,222,333],
  "stringArrayName" : ["a","b","c"]


}

Change your Main.c like so

#include <stdlib.h>
#include <stdio.h>
#include "ClasseAusiliaria.h"

int main(void)
{
  int risultato;
  risultato = addizione(5,6);
  printf("%d\n",risultato);
}

Create ClasseAusiliaria.h like so

extern int addizione(int a, int b);

I then compiled and ran your code, I got an output of

11

I was struggling to figure it out how to put a div over an image like this:

No matter how I configured z-index in both divs (the image wrapper) and the section I was getting this:

Turns out I hadn't set up the background of the section to be background: white;

so basically it's like this:

<div class="img-wrp">
  <img src="myimage.svg"/>
</div>
<section>
 <other content>
</section>

section{
  position: relative;
  background: white; /* THIS IS THE IMPORTANT PART NOT TO FORGET */
}
.img-wrp{
  position: absolute;
  z-index: -1; /* also worked with 0 but just to be sure */
}

When using java -cp you are required to provide fully qualified main class name, e.g.

java -cp com.mycompany.MyMain

When using java -jar myjar.jar your jar file must provide the information about main class via manifest.mf contained into the jar file in folder META-INF:

Main-Class: com.mycompany.MyMain

Try this

var URL = "scratch.mit.edu/projects";
var mainURL = window.location.pathname;

if (mainURL == URL) {
    mainURL += ( mainURL.match( /[\?]/g ) ? '&' : '#' ) + '_bypasssharerestrictions_';
    console.log(mainURL)
}

funcdict = {
  'mypackage.mymodule.myfunction': mypackage.mymodule.myfunction,
    ....
}

funcdict[myvar](parameter1, parameter2)

You're missing the () after ToString that marks it as a function call vs. a function reference (the kind you pass to delegates), which incidentally is why c# has no AddressOf operator, it's implied by how you type it.

Try this:

string guid = System.Guid.NewGuid().ToString();

you put this css for svg circle.

svg:hover circle{
    fill: #F6831D;
    stroke-dashoffset: 0;
    stroke-dasharray: 700;
    stroke-width: 2;
}

Brad Wilson has a couple great articles on unobtrusive validation and unobtrusive ajax.
It is also shown very nicely in this Pluralsight video in the section on " AJAX and JavaScript".

Basically, it is simply Javascript validation that doesn't pollute your source code with its own validation code. This is done by making use of data- attributes in HTML.

VB.NET Sample Code

Dim A as String = "5.3"
Dim B as Double

B = CDbl(Val(A)) '// Val do hard work

'// Get output 
MsgBox (B) '// Output is 5,3 Without Val result is 53.0

Step 1: (Install qemu-kvm)

sudo apt install qemu-kvm

Step 2: (Add your user to kvm group using)

sudo adduser username kvm

Step 3: (If still showing permission denied)

sudo chown username /dev/kvm

Final step:

ls -al /dev/kvm

The configuration seem alright, except that you should use excludeFilters instead of excludes:

@Configuration @EnableSpringConfigured
@ComponentScan(basePackages = {"com.example"}, excludeFilters={
  @ComponentScan.Filter(type=FilterType.ASSIGNABLE_TYPE, value=Foo.class)})
public class MySpringConfiguration {}

If you are receiving this error in a WebSphere container, then make sure you set your Apps class loading policy correctly. I had to change mine from the default to 'parent last' and also ‘Single class loader for application’ for the WAR policy. This is because in my case the commons-io*.jar was packaged with in the application, so it had to be loaded first.

Try wrapping whatever div you have flexboxed with flex-direction: column in a container that is also flexboxed.

I just tested this in IE11 and it works. An odd fix, but until Microsoft makes their internal bug fix external...it'll have to do!

HTML:

<div class="FlexContainerWrapper">
    <div class="FlexContainer">
        <div class="FlexItem">
            <p>I should be centered.</p>
        </div>
    </div>
</div>

CSS:

html, body {
  height: 100%;
}

.FlexContainerWrapper {
  display: flex;
  flex-direction: column;
  height: 100%;
}

.FlexContainer {
  align-items: center;
  background: hsla(0,0%,0%,.1);
  display: flex;

Other than win32, if your company had set up you web outlook, you can also try PYTHON REST API, which is officially made by Microsoft. (https://msdn.microsoft.com/en-us/office/office365/api/mail-rest-operations)

In case that you are demanded to keep the jar library as small as possible, you can include the SMTP/POP3/IMAP function separately to avoid the "too many methods in the dex" problem.

You can choose the wanted jar libraries from the javanet web page, for example, mailapi.jar + imap.jar can enable you to access icloud, hotmail mail server in IMAP protocol. (with the help of additional.jar and activation.jar)

Here's a solution that does not require any libraries.

This routine transmits every file in the directory d:/data/mpf10 to urlToConnect

String boundary = Long.toHexString(System.currentTimeMillis());
URLConnection connection = new URL(urlToConnect).openConnection();
connection.setDoOutput(true);
connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary);
PrintWriter writer = null;
try {
    writer = new PrintWriter(new OutputStreamWriter(connection.getOutputStream(), "UTF-8"));
    File dir = new File("d:/data/mpf10");
    for (File file : dir.listFiles()) {
        if (file.isDirectory()) {
            continue;
        }
        writer.println("--" + boundary);
        writer.println("Content-Disposition: form-data; name=\"" + file.getName() + "\"; filename=\"" + file.getName() + "\"");
        writer.println("Content-Type: text/plain; charset=UTF-8");
        writer.println();
        BufferedReader reader = null;
        try {
            reader = new BufferedReader(new InputStreamReader(new FileInputStream(file), "UTF-8"));
            for (String line; (line = reader.readLine()) != null;) {
                writer.println(line);
            }
        } finally {
            if (reader != null) {
                reader.close();
            }
        }
    }
    writer.println("--" + boundary + "--");
} finally {
    if (writer != null) writer.close();
}
// Connection is lazily executed whenever you request any status.
int responseCode = ((HttpURLConnection) connection).getResponseCode();
// Handle response

If you're using the close class in your modals, the following will work. Depending on your use case, I generally recommend filtering to only the visible modal if there are more than one modals with the close class.

$('.close:visible').click();

I wanted something pretty close to this - the moment a user picks an item, even by just hitting the arrow keys to one (focus), I want that data item attached to the tag in question. When they type again without picking another item, I want that data cleared.

(function() {
    var lastText = '';

    $('#MyTextBox'), {
        source: MyData
    })
    .on('autocompleteselect autocompletefocus', function(ev, ui) {
        lastText = ui.item.label;
        jqTag.data('autocomplete-item', ui.item);
    })
    .keyup(function(ev) {
        if (lastText != jqTag.val()) {
            // Clear when they stop typing
            jqTag.data('autocomplete-item', null);

            // Pass the event on as autocompleteclear so callers can listen for select/clear
            var clearEv = $.extend({}, ev, { type: 'autocompleteclear' });
            return jqTag.trigger(clearEv);
    });
})();

With this in place, 'autocompleteselect' and 'autocompletefocus' still fire right when you expect, but the full data item that was selected is always available right on the tag as a result. 'autocompleteclear' now fires when that selection is cleared, generally by typing something else.

The answer by @Phrogz is great, but doesn't work on Windows. Here's how to tag an old commit with the commit's original date using Powershell:

git checkout 9fceb02
$env:GIT_COMMITTER_DATE = git show --format=%aD | Select -First 1
git tag v1.2
git checkout master

It selects all elements where the class name contains the string "span" somewhere. There's also ^= for the beginning of a string, and $= for the end of a string. Here's a good reference for some CSS selectors.

I'm only familiar with the bootstrap classes spanX where X is an integer, but if there were other selectors that ended in span, it would also fall under these rules.

It just helps to apply blanket CSS rules.

Yes: logrotate --force $CONFIG_FILE

Use this in WebApiConfig.cs class :

var json = config.Formatters.JsonFormatter;
json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
config.Formatters.Remove(config.Formatters.XmlFormatter);

This command actually works

\curl -L https://get.rvm.io | bash -s stable --ruby

You can use ng-bind-html, don't forget to inject $sanitize service into your module Hope it helps

I know this message is old and was a long time ago - but i also had problem with with the exact same error:

the problem I had was relates to the fact the encrypted text was converted to String and to byte[] when trying to DECRYPT it.

    private Key getAesKey() throws Exception {
    return new SecretKeySpec(Arrays.copyOf(key.getBytes("UTF-8"), 16), "AES");
}

private Cipher getMutual() throws Exception {
    Cipher cipher = Cipher.getInstance("AES");
    return cipher;// cipher.doFinal(pass.getBytes());
}

public byte[] getEncryptedPass(String pass) throws Exception {
    Cipher cipher = getMutual();
    cipher.init(Cipher.ENCRYPT_MODE, getAesKey());
    byte[] encrypted = cipher.doFinal(pass.getBytes("UTF-8"));
    return encrypted;

}

public String getDecryptedPass(byte[] encrypted) throws Exception {
    Cipher cipher = getMutual();
    cipher.init(Cipher.DECRYPT_MODE, getAesKey());
    String realPass = new String(cipher.doFinal(encrypted));
    return realPass;
}

import os,sys
# Store current working directory
pwd = os.path.dirname(__file__)
# Append current directory to the python path
sys.path.append(pwd)

Use the INTERVAL type to it. E.g:

--yesterday
SELECT NOW() - INTERVAL '1 DAY';

--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;

Then you can do the following on your query:

SELECT 
    org_id,
    count(accounts) AS COUNT,
    ((date_at) - INTERVAL '1 DAY') AS dateat
FROM 
    sourcetable
WHERE 
    date_at <= now() - INTERVAL '130 DAYS'
GROUP BY 
    org_id,
    dateat;

TIPS

Tip 1

You can append multiple operands. E.g.: how to get last day of current month?

SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';

Tip 2

You can also create an interval using make_interval function, useful when you need to create it at runtime (not using literals):

SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);

The proper way to remove a cookie is to set the max age to 0 and add the cookie back to the HttpServletResponse object.

Most people don't realize or forget to add the cookie back onto the response object. By doing that it will expire and remove the cookie immediately.

...retrieve cookie from HttpServletRequest
cookie.setMaxAge(0);
response.addCookie(cookie);

The first one is the correct one, and IMHO the more efficient one, since the second 'solution' instantiates a new string instance.

• Using spring boot you will no need to build configuration. This will have done automatically when you create project.

• If you use spring MVC you need to build configuration yourself. It is more complicated, but it is crucial.

For me the cause of this issue under Rails 4 was a missing,

<%= csrf_meta_tags %>

Line in my main application layout. I had accidently deleted it when I rewrote my layout.

If this isn't in the main layout you will need it in any page that you want a CSRF token on.

Firebug.

Then, in your javascript:

var blah = {something: 'hi', another: 'noway'};
console.debug("Here is blah: %o", blah);

Now you can look at the console, click on the statement and see what is inside blah

When I was doing the same query, I had hard time adjusting the solutions to my case, though all the previous answers have good insights.

Here is a solution when one has to acquire a list of unique objects, NOT strings. Let's say, one has a list of Record object. Record class has only properties of type String, NO property of type int. Here implementing hashCode() becomes difficult as hashCode() needs to return an int.

The following is a sample Record Class.

public class Record{

    String employeeName;
    String employeeGroup;

    Record(String name, String group){  
        employeeName= name;
        employeeGroup = group;    
    }
    public String getEmployeeName(){
        return employeeName;
    }
    public String getEmployeeGroup(){
        return employeeGroup;
    }

  @Override
    public boolean equals(Object o){
         if(o instanceof Record){
            if (((Record) o).employeeGroup.equals(employeeGroup) &&
                  ((Record) o).employeeName.equals(employeeName)){
                return true;
            }
         }
         return false;
    }

    @Override
    public int hashCode() { //this should return a unique code
        int hash = 3; //this could be anything, but I would chose a prime(e.g. 5, 7, 11 )
        //again, the multiplier could be anything like 59,79,89, any prime
        hash = 89 * hash + Objects.hashCode(this.employeeGroup); 
        return hash;
    }

As suggested earlier by others, the class needs to override both the equals() and the hashCode() method to be able to use HashSet.

Now, let's say, the list of Records is allRecord(List<Record> allRecord).

Set<Record> distinctRecords = new HashSet<>();

for(Record rc: allRecord){
    distinctRecords.add(rc);
}

This will only add the distinct Records to the Hashset, distinctRecords.

Hope this helps.

Handling Errors

A sort of an "older style" of error handling is available to us in VBScript, that does make use of On Error Resume Next. First we enable that (often at the top of a file; but you may use it in place of the first Err.Clear below for their combined effect), then before running our possibly-error-generating code, clear any errors that have already occurred, run the possibly-error-generating code, and then explicitly check for errors:

On Error Resume Next
' ...
' Other Code Here (that may have raised an Error)
' ...
Err.Clear      ' Clear any possible Error that previous code raised
Set myObj = CreateObject("SomeKindOfClassThatDoesNotExist")
If Err.Number <> 0 Then
    WScript.Echo "Error: " & Err.Number
    WScript.Echo "Error (Hex): " & Hex(Err.Number)
    WScript.Echo "Source: " &  Err.Source
    WScript.Echo "Description: " &  Err.Description
    Err.Clear             ' Clear the Error
End If
On Error Goto 0           ' Don't resume on Error
WScript.Echo "This text will always print."

Above, we're just printing out the error if it occurred. If the error was fatal to the script, you could replace the second Err.clear with WScript.Quit(Err.Number).

Also note the On Error Goto 0 which turns off resuming execution at the next statement when an error occurs.

If you want to test behavior for when the Set succeeds, go ahead and comment that line out, or create an object that will succeed, such as vbscript.regexp.

The On Error directive only affects the current running scope (current Sub or Function) and does not affect calling or called scopes.

Raising Errors

If you want to check some sort of state and then raise an error to be handled by code that calls your function, you would use Err.Raise. Err.Raise takes up to five arguments, Number, Source, Description, HelpFile, and HelpContext. Using help files and contexts is beyond the scope of this text. Number is an error number you choose, Source is the name of your application/class/object/property that is raising the error, and Description is a short description of the error that occurred.

If MyValue <> 42 Then
    Err.Raise(42, "HitchhikerMatrix", "There is no spoon!")
End If

You could then handle the raised error as discussed above.

The training and validation sets are used during training.

    for each training data instance
        propagate error through the network
        adjust the weights
        calculate the accuracy over training data
    for each validation data instance
        calculate the accuracy over the validation data
    if the threshold validation accuracy is met
        exit training

        continue training

Once you're finished training, then you run against your testing set and verify that the accuracy is sufficient.

Training Set: this data set is used to adjust the weights on the neural network.

Validation Set: this data set is used to minimize overfitting. You're not adjusting the weights of the network with this data set, you're just verifying that any increase in accuracy over the training data set actually yields an increase in accuracy over a data set that has not been shown to the network before, or at least the network hasn't trained on it (i.e. validation data set). If the accuracy over the training data set increases, but the accuracy over the validation data set stays the same or decreases, then you're overfitting your neural network and you should stop training.

Testing Set: this data set is used only for testing the final solution in order to confirm the actual predictive power of the network.

Happy Coding!!

It will not work like this, put both images as background images:

.bg-img {
    background:url(images/yourImg.jpg) no-repeat 0 0;
}

.bg-img:hover {
    background:url(images/yourImg-1.jpg) no-repeat 0 0;
}

It could be a case-sensitivity issue. Normally tables and columns are not case sensitive, but they will be if you use quotation marks. For example:

create table bad_design("goodLuckSelectingThisColumn" number);

I am updating a simple solution. First add an id to your segue which presents modal. Than in properties change it's presentation style to "Over Current Context". Than add this code in presenting view controller (The controller which is presenting modal).

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    let Device = UIDevice.currentDevice()

    let iosVersion = NSString(string: Device.systemVersion).doubleValue

    let iOS8 = iosVersion >= 8
    let iOS7 = iosVersion >= 7 && iosVersion < 8
    if((segue.identifier == "chatTable")){

    if (iOS8){


          }
        else {

            self.navigationController?.modalPresentationStyle = UIModalPresentationStyle.CurrentContext


        }
    }
}

Make sure you change segue.identifier to your own id ;)

Use a for loop instead of .forEach()

var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false

    var a = call['a'], b = call['b']
     
    if(a == null || b == null) {
        result = false
        break
    }
}

If you wish to automate scraping of large amount pages or data, then you could try Gotz ETL.

It is completely model driven like a real ETL tool. Data structure, task workflow and pages to scrape are defined with a set of XML definition files and no coding is required. Query can be written either using Selectors with JSoup or XPath with HtmlUnit.

The hex editor plugin mentioned by ellak still works, but it seems that you need the TextFX Characters plugin as well.

I initially installed only the hex plugin and Notepad++ would no longer pop up; instead it started eating memory (killed it at 1.2 GB). I removed it again and for other reasons installed the TextFX plugin (based on Find multiple lines in Notepad++)

Out of curiosity I installed the hex plugin again and now it works.

Note that this is on a fresh install of Windows 7 64 bit.

you must kill child process too if any spawned to kill successfully your process

taskkill /IM "process_name" /T /F

/T = kills child process

/F = forceful termination of your process

Edit for the new information

Thisis a problem with finding your SMTP server from what I can see, though you say that it only happens on some emails. Are you using more than one smtp server and if so maybe you can tract the issue down to one in particular, if not it may be that the speed/amount of emails you are sending is causing your smtp server some issue.

I was getting this error when executing in python3,I got the same program working by simply executing in python2

Instead of replace we can force culture like

var x = decimal.Parse("18,285", new NumberFormatInfo() { NumberDecimalSeparator = "," });

it will give output 18.285

From What is Unicode:

Fundamentally, computers just deal with numbers. They store letters and other characters by assigning a number for each one.

......

Unicode provides a unique number for every character, no matter what the platform, no matter what the program, no matter what the language.

So when a computer represents a string, it finds characters stored in the computer of the string through their unique Unicode number and these figures are stored in memory. But you can't directly write the string to disk or transmit the string on network through their unique Unicode number because these figures are just simple decimal number. You should encode the string to byte string, such as UTF-8. UTF-8 is a character encoding capable of encoding all possible characters and it stores characters as bytes (it looks like this). So the encoded string can be used everywhere because UTF-8 is nearly supported everywhere. When you open a text file encoded in UTF-8 from other systems, your computer will decode it and display characters in it through their unique Unicode number. When a browser receive string data encoded UTF-8 from network, it will decode the data to string (assume the browser in UTF-8 encoding) and display the string.

In python3, you can transform string and byte string to each other:

>>> print('??'.encode('utf-8'))
b'\xe4\xb8\xad\xe6\x96\x87'
>>> print(b'\xe4\xb8\xad\xe6\x96\x87'.decode('utf-8'))
?? 

In a word, string is for displaying to humans to read on a computer and byte string is for storing to disk and data transmission.

What error is it giving you?

If you do exactly this:

data = json.loads('{"lat":444, "lon":555}')

Then:

data['lat']

SHOULD NOT give you any error at all.

Try this:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

For some odd reason this part

$el.empty(); // remove old options

from CMS solution didn't work for me, so instead of that I've simply used this

el.html(' ');

And it's works. So my working code now looks like that:

var newOptions = {
    "Option 1":"option-1",
    "Option 2":"option-2"
};

var $el = $('.selectClass');
$el.html(' ');
$.each(newOptions, function(key, value) {
    $el.append($("<option></option>")
    .attr("value", value).text(key));
});

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.

The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

char *words; // setting this to NULL would have prevented the issue

if (condition) {
    words = malloc( 512 );

    /* calling free sometime later works here */

    free(words)
} else {

    /* do not allocate words in this branch */
}

/* free(words);  -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:

*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***
glibc detected, realloc(): invalid pointer

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

$("tr.item").each(function() {
  $this = $(this);
  var value = $this.find("span.value").html();
  var quantity = $this.find("input.quantity").val();
});

Make sure your server is sending the font files with the right mime/type.

I recently have the same problem using nginx because some font mime types are missing from its vanilla /etc/nginx/mime.types file.

I fixed the issue adding the missing mime types in the location where I needed them like this:

location /app/fonts/ {

  #Fonts dir
  alias /var/www/app/fonts/;

  #Include vanilla types
  include mime.types;

  #Missing mime types
  types  {font/truetype ttf;}
  types  {application/font-woff woff;}

The Law of Leaky Abstractions by Joel Spolsky

\df <schema>.*

in psql gives the necessary information.

To see the query that's used internally connect to a database with psql and supply an extra "-E" (or "--echo-hidden") option and then execute the above command.

• document.getElementById('frmMain').elements
  assumes the form has an ID and that the ID is unique as IDs should be. Although it also accesses a name attribute in IE, please add ID to the element if you want to use getElementById

• document.getElementsByName('frmMain')[0].elements
  will get the elements of the first object named frmMain on the page - notice the plural getElements - it will return a collection.

• document.getElementsByTagName('form')[0].elements
  will get the elements of the first form on the page based on the tag - again notice the plural getElements

A great alternative is

• document.querySelector("form").elements
  will get the elements of the first form on the page. The "form" is a valid CSS selector

• document.querySelectorAll("form")[0].elements
  notice the All - it is a collection. The [0] will get the elements of the first form on the page. The "form" is a valid CSS selector

In all of the above, the .elements can be replaced by for example .querySelectorAll("[type=text]") to get all text elements
