Setting or Updating of Reactive Forms Form Control values can be done using both patchValue and setValue. However, it might be better to use patchValue in some instances.

patchValue does not require all controls to be specified within the parameters in order to update/set the value of your Form Controls. On the other hand, setValue requires all Form Control values to be filled in, and it will return an error if any of your controls are not specified within the parameter.

In this scenario, we will want to use patchValue, since we are only updating user and questioning:

this.qService.editQue([params["id"]]).subscribe(res => {
  this.question = res;
  this.editqueForm.patchValue({
    user: this.question.user,
    questioning: this.question.questioning
  });
});

EDIT: If you feel like doing some of ES6's Object Destructuring, you may be interested to do this instead

const { user, questioning } = this.question;

this.editqueForm.patchValue({
  user,
  questioning
});

Ta-dah!

If that helps anyone, (even if this is kind of poor as we must only allow this for dev purpose) here is a Java solution as I encountered the same issue. [Edit] Do not use the wild card * as it is a bad solution, use localhost if you really need to have something working locally.

public class SimpleCORSFilter implements Filter {

public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
    HttpServletResponse response = (HttpServletResponse) res;
    response.setHeader("Access-Control-Allow-Origin", "my-authorized-proxy-or-domain");
    response.setHeader("Access-Control-Allow-Methods", "POST, GET");
    response.setHeader("Access-Control-Max-Age", "3600");
    response.setHeader("Access-Control-Allow-Headers", "Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");
    chain.doFilter(req, res);
}

public void init(FilterConfig filterConfig) {}

public void destroy() {}

}

You have to set to element_blank() in theme() elements you need to remove

ggplot(data = diamonds, mapping = aes(x = clarity)) + geom_bar(aes(fill = cut))+
  theme(axis.title.x=element_blank(),
        axis.text.x=element_blank(),
        axis.ticks.x=element_blank())

Structure in C

First you need to declare your structure:

struct mystruct{
 char element_1,
 char element_2
};

Instantiate C structure

Once you declared your structure , you can instantiate a variable that has as type your structure using either:

mystruct struct_example;

or :

mystruct* struct_example;

For the first use case you can access the varaiable eleemnet using the following syntax: struct_example.element_1 = 5;

For the second use case which is having a pointer to variable of type your structure, to be able to access the variable structure you need an arrow:

struct_example->element_1 = 5;

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L] 

This must definitely work.. have a try

I wrote an assembly binding log viewer named Fusion++ and put it on GitHub.

You can get the latest release from here or via chocolatey (choco install fusionplusplus).

I hope you and some of the visitors in here can save some worthy lifetime minutes with it.

I know this question is old and has lots of great answers but I post this answer because of it's new flavor (es5+)

ls -lR is to display all files, directories and sub directories of the current directory ls -lR | more is used to show all the files in a flow.

<html>  
<head>  
<script language="javascript" type="text/javascript">  
function SetFocus(InputID)  
{  
   document.getElementById(InputID).focus();  
}  
</script>  
</head>  
<body onload="SetFocus('Box2')">  
<input id="Box1" size="30" /><br/>  
<input id="Box2" size="30" />

Another way to get this error is by accidentally writing the definition of something in an anonymous namespace:

foo.h:

namespace foo {
    void bar();
}

foo.cc:

namespace foo {
    namespace {  // wrong
        void bar() { cout << "hello"; };
    }
}

other.cc file:

#include "foo.h"

void baz() {
    foo::bar();
}

By using Reflector, you can see, that Contains is implemented using IndexOf. Here's the implementation.

public bool Contains(string value)
{
   return (this.IndexOf(value, StringComparison.Ordinal) >= 0);
}

So Contains is likely a wee bit slower than calling IndexOf directly, but I doubt that it will have any significance for the actual performance.

class Foo          (object):
    # ^class name  #^ inherits from object

    bar = "Bar" #Class attribute.

    def __init__(self):
        #        #^ The first variable is the class instance in methods.  
        #        #  This is called "self" by convention, but could be any name you want.
        #^ double underscore (dunder) methods are usually special.  This one 
        #  gets called immediately after a new instance is created.

        self.variable = "Foo" #instance attribute.
        print self.variable, self.bar  #<---self.bar references class attribute
        self.bar = " Bar is now Baz"   #<---self.bar is now an instance attribute
        print self.variable, self.bar  

    def method(self, arg1, arg2):
        #This method has arguments.  You would call it like this:  instance.method(1, 2)
        print "in method (args):", arg1, arg2
        print "in method (attributes):", self.variable, self.bar


a = Foo() # this calls __init__ (indirectly), output:
                 # Foo bar
                 # Foo  Bar is now Baz
print a.variable # Foo
a.variable = "bar"
a.method(1, 2) # output:
               # in method (args): 1 2
               # in method (attributes): bar  Bar is now Baz
Foo.method(a, 1, 2) #<--- Same as a.method(1, 2).  This makes it a little more explicit what the argument "self" actually is.

class Bar(object):
    def __init__(self, arg):
        self.arg = arg
        self.Foo = Foo()

b = Bar(a)
b.arg.variable = "something"
print a.variable # something
print b.Foo.variable # Foo

rising_edge is defined as:

FUNCTION rising_edge  (SIGNAL s : std_ulogic) RETURN BOOLEAN IS
BEGIN
    RETURN (s'EVENT AND (To_X01(s) = '1') AND
                        (To_X01(s'LAST_VALUE) = '0'));
END;

FUNCTION To_X01  ( s : std_ulogic ) RETURN  X01 IS
BEGIN
    RETURN (cvt_to_x01(s));
END;

CONSTANT cvt_to_x01 : logic_x01_table := (
                     'X',  -- 'U'
                     'X',  -- 'X'
                     '0',  -- '0'
                     '1',  -- '1'
                     'X',  -- 'Z'
                     'X',  -- 'W'
                     '0',  -- 'L'
                     '1',  -- 'H'
                     'X'   -- '-'
                    );

If your clock only goes from 0 to 1, and from 1 to 0, then rising_edge will produce identical code. Otherwise, you can interpret the difference.

Personally, my clocks only go from 0 to 1 and vice versa. I find rising_edge(clk) to be more descriptive than the (clk'event and clk = '1') variant.

If the above methods did not work, (such as restarting, killing, rebooting, reconfigure, updating, permissions .. etc) the bug might be in the last opened files tab. I had a file I was accessing from data/data/... and whenever I opened A.S, the panel always showed the error. Just close the tabs and restart AS.

For those that come here using MariaDB:

Note that MariaDB allows DROP CONSTRAINT statements in general, for example for dropping check constraints:

ALTER TABLE table_name
DROP CONSTRAINT constraint_name;

Run a packet sniffer (e.g., Wireshark) also on the peer to see whether it's the peer who's sending the RST or someone in the middle.

Each datetime class provides a variety of constructors. These include the Object constructor. This allows you to construct, for example, DateTime from the following objects:

* Date - a JDK instant
* Calendar - a JDK calendar
* String - in ISO8601 format
* Long - in milliseconds
* any Joda-Time datetime class

• First create the menu layouts in the your Activity layout xml file. For e.g. a linear layout with horizontal orientation and include a TextView for label then a Floating Action Button beside the TextView.

• Create the menu layouts as per your need and number.

• Create a Base Floating Action Button and on its click of that change the visibility of the Menu Layouts.

        </android.support.constraint.ConstraintLayout>

These are the animations-

Opening animation of FAB Menu:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true">
<scale
    android:duration="300"
    android:fromXScale="0"
    android:fromYScale="0"
    android:interpolator="@android:anim/linear_interpolator"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toXScale="1"
    android:toYScale="1" />
<alpha
    android:duration="300"
    android:fromAlpha="0.0"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toAlpha="1.0" />

</set>

Closing animation of FAB Menu:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true">
<scale
    android:duration="300"
    android:fromXScale="1"
    android:fromYScale="1"
    android:interpolator="@android:anim/linear_interpolator"
    android:pivotX="50%"
    android:pivotY="50%"

    android:fromAlpha="1.0"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toAlpha="0.0" />
</set>

Then in my Activity I've simply used the animations above to show and hide the FAB menu :

Show Fab Menu:

  private void expandFabMenu() {

    ViewCompat.animate(binding.baseFloatingActionButton).rotation(45.0F).withLayer().setDuration(300).setInterpolator(new OvershootInterpolator(10.0F)).start();
    binding.createLayout.startAnimation(fabOpenAnimation);
    binding.shareLayout.startAnimation(fabOpenAnimation);
    binding.createFab.setClickable(true);
    binding.shareFab.setClickable(true);
    isFabMenuOpen = true;

}

Close Fab Menu:

private void collapseFabMenu() {

    ViewCompat.animate(binding.baseFloatingActionButton).rotation(0.0F).withLayer().setDuration(300).setInterpolator(new OvershootInterpolator(10.0F)).start();
    binding.createLayout.startAnimation(fabCloseAnimation);
    binding.shareLayout.startAnimation(fabCloseAnimation);
    binding.createFab.setClickable(false);
    binding.shareFab.setClickable(false);
    isFabMenuOpen = false;

}

Remember that the dot notation in a Django template is used for four different notations in Python. In a template, foo.bar can mean any of:

foo[bar]       # dictionary lookup
foo.bar        # attribute lookup
foo.bar()      # method call
foo[bar]       # list-index lookup

It tries them in this order until it finds a match. So foo.3 will get you your list index because your object isn't a dict with 3 as a key, doesn't have an attribute named 3, and doesn't have a method named 3.

When the JVM tries to run your application, it calls your main method statically; something like this:

LinkedList.main();

That means there is no instance of your LinkedList class. In order to call your toString() method, you can create a new instance of your LinkedList class.

So the body of your main method should be like this:

public static void main(String[] args){
    // creating an instance of LinkedList class
    LinkedList ll = new LinkedList();

    // adding some data to the list
    ll.insertFront(1);
    ll.insertFront(2);
    ll.insertFront(3);
    ll.insertBack(4);

    System.out.println(ll.toString());
}

std::copy does the job as far as moving elements is concerned:

 #include <algorithm>

 std::copy(array+3, array+5, array+2);

Note that the precondition for copy is that the destination must not be in the source range. It's permissible for the ranges to overlap.

Also, because of the way arrays work in C++, this doesn't "shorten" the array. It just shifts elements around within it. There is no way to change the size of an array, but if you're using a separate integer to track its "size" meaning the size of the part you care about, then you can of course decrement that.

So, the array you'll end up with will be as if it were initialized with:

int array[] = {1,2,4,5,5};

Checkout this working Plunker

<select (change)="onItemChange($event.target.value)">
    <option *ngFor="#value of values" [value]="value.key">{{value.value}}</option>
</select>

You can get the ident of the current running thread. The ident could be reused for other threads, if the current thread ends.

When you crate an instance of Thread, a name is given implicit to the thread, which is the pattern: Thread-number

The name has no meaning and the name don't have to be unique. The ident of all running threads is unique.

import threading


def worker():
    print(threading.current_thread().name)
    print(threading.get_ident())


threading.Thread(target=worker).start()
threading.Thread(target=worker, name='foo').start()

The function threading.current_thread() returns the current running thread. This object holds the whole information of the thread.

I just started facing the same issue after the latest CyanogenMod nightly update (12th aug 2013) on my Samsung Galaxy S III.

I used the ADB binaries suggested in the topmost answer (by hack_on edited by w. allison), and I got a prompt on my phone asking to allow access to my PC (its RSA key)!! It's working fine now.

Download link (ADB, Fastboot and related binaries only): https://dl.google.com/android/repository/platform-tools_r16.0.1-windows.zip

If you are using jackson you can easily achieve this with configuring a SerializationFeature in your ObjectMapper:

com.fasterxml.jackson.databind.ObjectMapper mapper = new ObjectMapper();

mapper.configure(SerializationFeature.INDENT_OUTPUT, true);

mapper.writeValueAsString(<yourObject>);

Thats it.

Here is a solution I came up with, this stores the symbols as chars and uses the char's int value to figure out if X or O has won (look at the Referee's code)

public class TicTacToe {
    public static final char BLANK = '\u0000';
    private final char[][] board;
    private int moveCount;
    private Referee referee;

    public TicTacToe(int gridSize) {
        if (gridSize < 3)
            throw new IllegalArgumentException("TicTacToe board size has to be minimum 3x3 grid");
        board = new char[gridSize][gridSize];
        referee = new Referee(gridSize);
    }

    public char[][] displayBoard() {
        return board.clone();
    }

    public String move(int x, int y) {
        if (board[x][y] != BLANK)
            return "(" + x + "," + y + ") is already occupied";
        board[x][y] = whoseTurn();
        return referee.isGameOver(x, y, board[x][y], ++moveCount);
    }

    private char whoseTurn() {
        return moveCount % 2 == 0 ? 'X' : 'O';
    }

    private class Referee {
        private static final int NO_OF_DIAGONALS = 2;
        private static final int MINOR = 1;
        private static final int PRINCIPAL = 0;
        private final int gridSize;
        private final int[] rowTotal;
        private final int[] colTotal;
        private final int[] diagonalTotal;

        private Referee(int size) {
            gridSize = size;
            rowTotal = new int[size];
            colTotal = new int[size];
            diagonalTotal = new int[NO_OF_DIAGONALS];
        }

        private String isGameOver(int x, int y, char symbol, int moveCount) {
            if (isWinningMove(x, y, symbol))
                return symbol + " won the game!";
            if (isBoardCompletelyFilled(moveCount))
                return "Its a Draw!";
            return "continue";
        }

        private boolean isBoardCompletelyFilled(int moveCount) {
            return moveCount == gridSize * gridSize;
        }

        private boolean isWinningMove(int x, int y, char symbol) {
            if (isPrincipalDiagonal(x, y) && allSymbolsMatch(symbol, diagonalTotal, PRINCIPAL))
                return true;
            if (isMinorDiagonal(x, y) && allSymbolsMatch(symbol, diagonalTotal, MINOR))
                return true;
            return allSymbolsMatch(symbol, rowTotal, x) || allSymbolsMatch(symbol, colTotal, y);
        }

        private boolean allSymbolsMatch(char symbol, int[] total, int index) {
            total[index] += symbol;
            return total[index] / gridSize == symbol;
        }

        private boolean isPrincipalDiagonal(int x, int y) {
            return x == y;
        }

        private boolean isMinorDiagonal(int x, int y) {
            return x + y == gridSize - 1;
        }
    }
}

Also here are my unit tests to validate it actually works

Full solution: https://github.com/nashjain/tictactoe/tree/master/java

Change .text to .textContent to get/set the text content.

Or since you're dealing with a single text node, use .firstChild.data in the same manner.

Also, let's make sensible use of a variable, and enjoy some code reduction and eliminate redundant DOM selection by caching the result of getElementById.

function toggleText(button_id) 
{
   var el = document.getElementById(button_id);
   if (el.firstChild.data == "Lock") 
   {
       el.firstChild.data = "Unlock";
   }
   else 
   {
     el.firstChild.data = "Lock";
   }
}

Or even more compact like this:

function toggleText(button_id)  {
   var text = document.getElementById(button_id).firstChild;
   text.data = text.data == "Lock" ? "Unlock" : "Lock";
}

If your looking to include a bunch of classes without having to define each class at once you can use:

$directories = array(
            'system/',
            'system/db/',
            'system/common/'
);
foreach ($directories as $directory) {
    foreach(glob($directory . "*.php") as $class) {
        include_once $class;
    }
}

This way you can just define the class on the php file containing the class and not a whole list of $thisclass = new thisclass();

As for how well it handles all the files? I'm not sure there might be a slight speed decrease with this.

UPDATE

You can use document.location.reload(true) as mentioned below instead of the forced trick below.

Replace your HTML with this:

<!DOCTYPE html>
<html>
    <head>
        <style type="text/css">
            body { 
                background-image: url('../Images/Black-BackGround.gif');
                background-repeat: repeat;
            }
            body td {
               font-Family: Arial; 
               font-size: 12px; 
            }
            #Nav a { 
                position:relative; 
                display:block; 
                text-decoration: none; 
                color:black; 
            }
        </style>
        <script type="text/javascript">
            function refreshPage () {
                var page_y = document.getElementsByTagName("body")[0].scrollTop;
                window.location.href = window.location.href.split('?')[0] + '?page_y=' + page_y;
            }
            window.onload = function () {
                setTimeout(refreshPage, 35000);
                if ( window.location.href.indexOf('page_y') != -1 ) {
                    var match = window.location.href.split('?')[1].split("&")[0].split("=");
                    document.getElementsByTagName("body")[0].scrollTop = match[1];
                }
            }
        </script>
    </head>
    <body><!-- BODY CONTENT HERE --></body>
</html>

Switch the order of the code: You're calling the click event before it is attached.

$(document).ready(function() {
      $("#checkbox_div input:radio").click(function() {

           alert("clicked");

      });

      $("input:radio:first").prop("checked", true).trigger("click");

});

Masking means to keep/change/remove a desired part of information. Lets see an image-masking operation; like- this masking operation is removing any thing that is not skin-

We are doing AND operation in this example. There are also other masking operators- OR, XOR.

Bit-Masking means imposing mask over bits. Here is a bit-masking with AND-

     1 1 1 0 1 1 0 1   [input]
(&)  0 0 1 1 1 1 0 0    [mask]
------------------------------
     0 0 1 0 1 1 0 0  [output]

So, only the middle 4 bits (as these bits are 1 in this mask) remain.

Lets see this with XOR-

     1 1 1 0 1 1 0 1   [input]
(^)  0 0 1 1 1 1 0 0    [mask]
------------------------------
     1 1 0 1 0 0 0 1  [output]

Now, the middle 4 bits are flipped (1 became 0, 0 became 1).

So, using bit-mask we can access individual bits [examples]. Sometimes, this technique may also be used for improving performance. Take this for example-

bool isOdd(int i) {
    return i%2;
}

This function tells if an integer is odd/even. We can achieve the same result with more efficiency using bit-mask-

bool isOdd(int i) {
    return i&1;
}

Short Explanation: If the least significant bit of a binary number is 1 then it is odd; for 0 it will be even. So, by doing AND with 1 we are removing all other bits except for the least significant bit i.e.:

     55  ->  0 0 1 1 0 1 1 1   [input]
(&)   1  ->  0 0 0 0 0 0 0 1    [mask]
---------------------------------------
      1  <-  0 0 0 0 0 0 0 1  [output]

I think this might help...

In order to break down user inputted dates (mm/dd/yyyy) in my scripts, I store the day, month, and year into an array, and then put the values into separate variables as follows:

DATE_ARRAY=(`echo $2 | sed -e 's/\// /g'`)
MONTH=(`echo ${DATE_ARRAY[0]}`)
DAY=(`echo ${DATE_ARRAY[1]}`)
YEAR=(`echo ${DATE_ARRAY[2]}`)

"^" For the begining of the line "$" for the end of it. Eg.:

var re = /^abc$/;

Would match "abc" but not "1abc" or "abc1". You can learn more at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions

This syntax will work in XHTML and does not work in IE6, but this is a non-javascript way:

option[selected] { background: #f00; }

If you want to do this on-the-fly, then you would have to go with javascript, the way others have suggested....

While it may work on some platforms, be aware that platform.architecture is not always a reliable way to determine whether python is running in 32-bit or 64-bit. In particular, on some OS X multi-architecture builds, the same executable file may be capable of running in either mode, as the example below demonstrates. The quickest safe multi-platform approach is to test sys.maxsize on Python 2.6, 2.7, Python 3.x.

$ arch -i386 /usr/local/bin/python2.7

The implementation of String.valueOf() that you see is the simplest way to meet the contract specified in the API: "The representation is exactly the one returned by the Integer.toString() method of one argument."

You need to slightly modify your compare function and use functools.cmp_to_key to pass it to sorted. Example code:

import functools

lst = [list(range(i, i+5)) for i in range(5, 1, -1)]

def fitness(item):
    return item[0]+item[1]+item[2]+item[3]+item[4]
def compare(item1, item2):
    return fitness(item1) - fitness(item2)

sorted(lst, key=functools.cmp_to_key(compare))

Output:

[[2, 3, 4, 5, 6], [3, 4, 5, 6, 7], [4, 5, 6, 7, 8], [5, 6, 7, 8, 9]]

Works :)

Traditional relational databases were designed as client/server database systems. They can be scaled horizontally but the process to do so tends to be complex and error prone. NewSQL databases like NuoDB are memory-centric distributed database systems designed to scale out horizontally while maintaining the SQL/ACID properties of traditional RDBMS.

For more information on NuoDB, read their technical white paper.

I found to be the best practice of using images, videos, etc. is:

• Change your files "Build action" to "Content". Be sure to check Copy to build directory.
  • Found on the "Right-Click" menu at the Solution Explorer window.
• Image Source in the following format:
  • "/«YourAssemblyName»;component/«YourPath»/«YourImage.png»"

Example

<Image Source="/WPFApplication;component/Images/Start.png" />

Benefits:

• Files are not embedded into the assembly.
  • The Resource Manager will raise some memory overflow problems with too many resources (at build time).
• Can be called between assemblies.

KeyPress is a higher level of abstraction than KeyDown (and KeyUp). KeyDown and KeyUp are hardware related: the actual action of a key on the keyboard. KeyPress is more "I received a character from the keyboard".

A little update for Bootstrap 3.

Bootstrap now has the following style for table cells:

.table tbody>tr>td
{
    vertical-align: top;
}

The way to go is to add a your own class, with the same selector:

.table tbody>tr>td.vert-align
{
    vertical-align: middle;
}

And then add it to your tds

<td class="vert-align"></td>

You need to install NUnitTestAdapter. The latest version of NUnit is 3.x.y (3.6.1) and you should install NUnit3TestAdapter along with NUnit 3.x.y

To install NUnit3TestAdapter in Visual Studio 2017, follow the steps below:

1. Right click on menu Project ? click "Manage NuGet Packages..." from the context menu
2. Go to the Browse tab and search for NUnit
3. Select NUnit3TestAdapter ? click Install at the right side ? click OK from the Preview pop up

insert is better from the point of exception safety.

The expression map[key] = value is actually two operations:

1. map[key] - creating a map element with default value.
2. = value - copying the value into that element.

An exception may happen at the second step. As result the operation will be only partially done (a new element was added into map, but that element was not initialized with value). The situation when an operation is not complete, but the system state is modified, is called the operation with "side effect".

insert operation gives a strong guarantee, means it doesn't have side effects (https://en.wikipedia.org/wiki/Exception_safety). insert is either completely done or it leaves the map in unmodified state.

http://www.cplusplus.com/reference/map/map/insert/:

If a single element is to be inserted, there are no changes in the container in case of exception (strong guarantee).

in build.gradle add Guava

    compile group: 'com.google.guava', name: 'guava', version: '27.0-jre'

and then

    public static List<String> splitByComma(String str) {
    Iterable<String> split = Splitter.on(",")
            .omitEmptyStrings()
            .trimResults()
            .split(str);
    return Lists.newArrayList(split);
    }

    public static String joinWithComma(Set<String> words) {
        return Joiner.on(", ").skipNulls().join(words);
    }

enjoy :)

For what its worth, in Pycharm it is: Right click on the root folder->Mark Directory as-> Sources Root

If you don't know the version ,current project has been made, you can omit --from command and type --migrate-only

ng update @angular/cli --migrate-only

In my experience, just pick a relatively high number (between 1024-65535) that you think is unlikely to be used by anything else. For example, port # 8080 and # 5555 are ones that I routinely use. Just pick a port number like this as opposed to just making the code randomly select it and then having to find the port number later is much easier for me.

For example, in my current ChatBot project:

port = 8080

Very easy from My side:-

''.join(sequenceofstrings) is what usually works best -- simplest and fastest.

Instead of checking for Build.VERSION.SDK_INT >= Build.VERSION_CODES.O as many answers suggest, there is a slightly simpler way -

Add the following line to the application section of AndroidManifest.xml file as explained in the Set Up a Firebase Cloud Messaging Client App on Android doc:

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_channel_id" 
        android:value="@string/default_notification_channel_id" />

Then add a line with a channel name to the values/strings.xml file:

<string name="default_notification_channel_id">default</string>

After that you will be able to use the new version of NotificationCompat.Builder constructor with 2 parameters (since the old constructor with 1 parameter has been deprecated in Android Oreo):

private void sendNotification(String title, String body) {
    Intent i = new Intent(this, MainActivity.class);
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pi = PendingIntent.getActivity(this,
            0 /* Request code */,
            i,
            PendingIntent.FLAG_ONE_SHOT);

    Uri sound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this, 
        getString(R.string.default_notification_channel_id))
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle(title)
            .setContentText(body)
            .setAutoCancel(true)
            .setSound(sound)
            .setContentIntent(pi);

    NotificationManager manager = 
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

    manager.notify(0, builder.build());
}

~/.bashrc is already a path to .bashrc.

If you do echo ~ you'll see that it's a path to your home directory.

Homebrew directory is /usr/local/bin. Homebrew is installed inside it and everything installed by homebrew will be installed there.

For example, if you do brew install python Homebrew will put Python binary in /usr/local/bin.

Finally, to add Homebrew directory to your path you can run echo "export PATH=/usr/local/lib:$PATH" >> ~/.bashrc. It will create .bashrc file if it doesn't exist and then append the needed line to the end.

You can check the result by running tail ~/.bashrc.

I had a similar situation while working on a joomla website.

Added a class name to the module to be affected. In your case:

<select name="funTimes" class="classname">

then made the following single line change in the css. Added the line

#elementId div.classname {style to be applied !important;}

worked well!

SQL Alchemy session objects have their own execute method:

result = db.session.execute('SELECT * FROM my_table WHERE my_column = :val', {'val': 5})

All your application queries should be going through a session object, whether they're raw SQL or not. This ensures that the queries are properly managed by a transaction, which allows multiple queries in the same request to be committed or rolled back as a single unit. Going outside the transaction using the engine or the connection puts you at much greater risk of subtle, possibly hard to detect bugs that can leave you with corrupted data. Each request should be associated with only one transaction, and using db.session will ensure this is the case for your application.

Also take note that execute is designed for parameterized queries. Use parameters, like :val in the example, for any inputs to the query to protect yourself from SQL injection attacks. You can provide the value for these parameters by passing a dict as the second argument, where each key is the name of the parameter as it appears in the query. The exact syntax of the parameter itself may be different depending on your database, but all of the major relational databases support them in some form.

Assuming it's a SELECT query, this will return an iterable of RowProxy objects.

You can access individual columns with a variety of techniques:

for r in result:
    print(r[0]) # Access by positional index
    print(r['my_column']) # Access by column name as a string
    r_dict = dict(r.items()) # convert to dict keyed by column names

Personally, I prefer to convert the results into namedtuples:

from collections import namedtuple

Record = namedtuple('Record', result.keys())
records = [Record(*r) for r in result.fetchall()]
for r in records:
    print(r.my_column)
    print(r)

If you're not using the Flask-SQLAlchemy extension, you can still easily use a session:

import sqlalchemy
from sqlalchemy.orm import sessionmaker, scoped_session

engine = sqlalchemy.create_engine('my connection string')
Session = scoped_session(sessionmaker(bind=engine))

s = Session()
result = s.execute('SELECT * FROM my_table WHERE my_column = :val', {'val': 5})

You can try something like this:

public interface PersonRepository extends CrudRepository<Person, Long> {
       @Query("select p from Person AS p"
       + " ,Name AS n"  
       + " where p.forename = n.forename "
       + " and p.surname = n.surname"
       + " and n = :name")
       Set<Person>findByName(@Param("name") Name name);
    }

This is how the ORM maps blank & null fields for Django 1.8

class Test(models.Model):
    charNull        = models.CharField(max_length=10, null=True)
    charBlank       = models.CharField(max_length=10, blank=True)
    charNullBlank   = models.CharField(max_length=10, null=True, blank=True)

    intNull         = models.IntegerField(null=True)
    intBlank        = models.IntegerField(blank=True)
    intNullBlank    = models.IntegerField(null=True, blank=True)

    dateNull        = models.DateTimeField(null=True)
    dateBlank       = models.DateTimeField(blank=True)
    dateNullBlank   = models.DateTimeField(null=True, blank=True)        

The database fields created for PostgreSQL 9.4 are :

CREATE TABLE Test (
  id              serial                    NOT NULL,

  "charNull"      character varying(10),
  "charBlank"     character varying(10)     NOT NULL,
  "charNullBlank" character varying(10),

  "intNull"       integer,
  "intBlank"      integer                   NOT NULL,
  "intNullBlank"  integer,

  "dateNull"      timestamp with time zone,
  "dateBlank"     timestamp with time zone  NOT NULL,
  "dateNullBlank" timestamp with time zone,
  CONSTRAINT Test_pkey PRIMARY KEY (id)
)

The database fields created for MySQL 5.6 are :

CREATE TABLE Test (
     `id`            INT(11)     NOT  NULL    AUTO_INCREMENT,

     `charNull`      VARCHAR(10) NULL DEFAULT NULL,
     `charBlank`     VARCHAR(10) NOT  NULL,
     `charNullBlank` VARCHAR(10) NULL DEFAULT NULL,

     `intNull`       INT(11)     NULL DEFAULT NULL,
     `intBlank`      INT(11)     NOT  NULL,
     `intNullBlank`  INT(11)     NULL DEFAULT NULL,

     `dateNull`      DATETIME    NULL DEFAULT NULL,
     `dateBlank`     DATETIME    NOT  NULL,
     `dateNullBlank` DATETIME    NULL DEFAULT NULL
)

Use prop() instead of attr() to set the value of checked. Also use :checkbox in find method instead of input and be specific.

Live Demo

$("#news_list tr").click(function() {
    var ele = $(this).find('input');
    if(ele.is(':checked')){
        ele.prop('checked', false);
        $(this).removeClass('admin_checked');
    }else{
        ele.prop('checked', true);
        $(this).addClass('admin_checked');
    }
});

Use prop instead of attr for properties like checked

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the .prop() method

If you can't rename the module to match Python naming conventions, create a new module to act as an intermediary:

 ---- foo_proxy.py ----
 tmp = __import__('foo-bar')
 globals().update(vars(tmp))

 ---- main.py ----
 from foo_proxy import * 

"Hard Coding" means something that you want to embeded with your program or any project that can not be changed directly. For example if you are using a database server, then you must hardcode to connect your database with your project and that can not be changed by user. Because you have hard coded.

Using the same approach of Philip Wallace, we can do like this:

    public Control GetControlByName(Control ParentCntl, string NameToSearch)
    {
        if (ParentCntl.Name == NameToSearch)
            return ParentCntl;

        foreach (Control ChildCntl in ParentCntl.Controls)
        {
            Control ResultCntl = GetControlByName(ChildCntl, NameToSearch);
            if (ResultCntl != null)
                return ResultCntl;
        }
        return null;
    }

Example:

    public void doSomething() 
    {
            TextBox myTextBox = (TextBox) this.GetControlByName(this, "mytextboxname");
            myTextBox.Text = "Hello!";
    }

I hope it help! :)

NodeJS, at one point (I think it was v0.6.x) had ArrayBuffer support. I created a small library for base64 encoding and decoding here, but since updating to v0.7, the tests (on NodeJS) fail. I'm thinking of creating something that normalizes this, but till then, I suppose Node's native Buffer should be used.

Set LDFLAGS and CFLAGS when you run make:

$ LDFLAGS="-L/home/me/local/lib" CFLAGS="-I/home/me/local/include" make

If you don't want to do that a gazillion times, export these in your .bashrc (or your shell equivalent). Also set LD_LIBRARY_PATH to include /home/me/local/lib:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/me/local/lib

You can try writing into the Documents folder. Here is a "debug" function I did for the debugging needs of my project:

Private Sub writeDebug(ByVal x As String)
    Dim path As String = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
    Dim FILE_NAME As String = path & "\mydebug.txt"
    MsgBox(FILE_NAME)
    If System.IO.File.Exists(FILE_NAME) = False Then
        System.IO.File.Create(FILE_NAME).Dispose()
    End If
    Dim objWriter As New System.IO.StreamWriter(FILE_NAME, True)
    objWriter.WriteLine(x)
    objWriter.Close()
End Sub

There are more standard folders you can access through the "SpecialFolder" object.

std::fill(v.begin(), v.end(), 0);

CASE isn't used for flow control... for this, you would need to use IF...

But, there's a set-based solution to this problem instead of the procedural approach:

UPDATE tblEmployee
SET 
  InOffice = CASE WHEN @NewStatus = 'InOffice' THEN -1 ELSE InOffice END,
  OutOffice = CASE WHEN @NewStatus = 'OutOffice' THEN -1 ELSE OutOffice END,
  Home = CASE WHEN @NewStatus = 'Home' THEN -1 ELSE Home END
WHERE EmpID = @EmpID

Note that the ELSE will preserves the original value if the @NewStatus condition isn't met.

Both Query is used for round down the nearest integer in MySQL

1. SELECT FLOOR(445.6) ;
2. SELECT NULL(222.456);

function getHash() {
  if (window.location.hash) {
    var hash = window.location.hash.substring(1);

    if (hash.length === 0) { 
      return false;
    } else { 
      return hash; 
    }
  } else { 
    return false; 
  }
}

I've had a similar requirement: I needed to inject a Spring-managed repository bean into my Person entity class ("entity" as in "something with an identity", for example an JPA entity). A Person instance has friends, and for this Person instance to return its friends, it shall delegate to its repository and query for friends there.

@Entity
public class Person {
    private static PersonRepository personRepository;

    @Id
    @GeneratedValue
    private long id;

    public static void setPersonRepository(PersonRepository personRepository){
        this.personRepository = personRepository;
    }

    public Set<Person> getFriends(){
        return personRepository.getFriends(id);
    }

    ...
}

.

@Repository
public class PersonRepository {

    public Person get Person(long id) {
        // do database-related stuff
    }

    public Set<Person> getFriends(long id) {
        // do database-related stuff
    }

    ...
}

So how did I inject that PersonRepository singleton into the static field of the Person class?

I created a @Configuration, which gets picked up at Spring ApplicationContext construction time. This @Configuration gets injected with all those beans that I need to inject as static fields into other classes. Then with a @PostConstruct annotation, I catch a hook to do all static field injection logic.

@Configuration
public class StaticFieldInjectionConfiguration {

    @Inject
    private PersonRepository personRepository;

    @PostConstruct
    private void init() {
        Person.setPersonRepository(personRepository);
    }
}

I don't think that can be done RELIABLY with built in methods on the native Date object. The toLocaleString method gets close, but if I am remembering correctly, it won't work correctly in IE < 10. If you are able to use a library for this task, MomentJS is a really amazing library; and it makes working with dates and times easy. Otherwise, I think you will have to write a basic function to give you the format that you are after.

function formatDate(date) {
    var year = date.getFullYear(),
        month = date.getMonth() + 1, // months are zero indexed
        day = date.getDate(),
        hour = date.getHours(),
        minute = date.getMinutes(),
        second = date.getSeconds(),
        hourFormatted = hour % 12 || 12, // hour returned in 24 hour format
        minuteFormatted = minute < 10 ? "0" + minute : minute,
        morning = hour < 12 ? "am" : "pm";

    return month + "/" + day + "/" + year + " " + hourFormatted + ":" +
            minuteFormatted + morning;
}

use this function for copy to clipboard

public void copyToClipboard(String copyText) {
    int sdk = android.os.Build.VERSION.SDK_INT;
    if (sdk < android.os.Build.VERSION_CODES.HONEYCOMB) {
        android.text.ClipboardManager clipboard = (android.text.ClipboardManager)
                getSystemService(Context.CLIPBOARD_SERVICE);
        clipboard.setText(copyText);
    } else {
        android.content.ClipboardManager clipboard = (android.content.ClipboardManager)
                getSystemService(Context.CLIPBOARD_SERVICE);
        android.content.ClipData clip = android.content.ClipData
                .newPlainText("Your OTP", copyText);
        clipboard.setPrimaryClip(clip);
    }
    Toast toast = Toast.makeText(getApplicationContext(),
            "Your OTP is copied", Toast.LENGTH_SHORT);
    toast.setGravity(Gravity.BOTTOM | Gravity.RIGHT, 50, 50);
    toast.show();
    //displayAlert("Your OTP is copied");
}

This problem might arise if you have different versions of programs.

For instance, you have 1-year old gcc and you want to compile a C++ source code. If you use mingw-get to install g++, gcc and g++ will suddenly have different versions and you ware likely to find yourself in this situation.

Running mingw-get update and mingw-get upgrade has solved this issue for me.

Go for the obvious first: Are you referencing well the jquery-ui.js file?

Try using the network tab of firebug to find if it is loaded, or the Information\View javascript code of the Web Developer Toolbar.

Here is how I fixed this issue on a Win7 x64 machine:

1 - error message:

"CoCreateInstance() failed Plkease check your registry entries CLSID{F088EA74-2E87-11D3-B1F3-00C0F03C37D3} and make sure you are logged in as an administrator"

2 - fix procedure:

• Start/type cmd/RightMouseClick on cmd.exe and choose to "Run as Administrator"
• typed: regsvr32 /s C:\Program Files\Autodesk\3ds Max Design 2015\atl.dll regsvr32 /s C:\Program Files\Autodesk\3ds Max Design 2015\MAXComponents.dll
• restart Win 7 and back in business again !

Hope this helps !

You can use gdb for this like objdump.

This excerpt is taken from http://sources.redhat.com/gdb/current/onlinedocs/gdb_9.html#SEC64

Here is an example showing mixed source+assembly for Intel x86:

  (gdb) disas /m main

End of assembler dump.

Set the CSS position: relative; on the box. This causes all absolute positions of objects inside to be relative to the corners of that box. Then set the following CSS on the "Bet 5 days ago" line:

position: absolute;
bottom: 0;
right: 0;

If you need to space the text farther away from the edge, you could change 0 to 2px or similar.

I usually start out with some combination of:

typeof(obj)
class(obj)
sapply(obj, class)
sapply(obj, attributes)
attributes(obj)
names(obj)

as appropriate based on what's revealed. For example, try with:

obj <- data.frame(a=1:26, b=letters)
obj <- list(a=1:26, b=letters, c=list(d=1:26, e=letters))
data(cars)
obj <- lm(dist ~ speed, data=cars)

..etc.

If obj is an S3 or S4 object, you can also try methods or showMethods, showClass, etc. Patrick Burns' R Inferno has a pretty good section on this (sec #7).

EDIT: Dirk and Hadley mention str(obj) in their answers. It really is much better than any of the above for a quick and even detailed peek into an object.

This is a browser issue rather than a javascript or JQuery issue; it's attempting to interpret the angle bracket as an HTML tag.

Try doing this when setting up your javascripts:

<script>
//<![CDATA[

    // insert teh codez

//]]>
</script>

Alternatively, move your javascript to a separate file.

Edit: Ahh.. with that link I've tracked it down. What I said was the issue wasn't the issue at all. this is the issue, stripped from the website:

<script type="text/javascript"
    $(document).ready(function() {
    $('#infobutton').click(function() {
        $('#music_descrip').dialog('open');
    });
        $('#music_descrip').dialog({
            title: '<img src="/images/text/text_mario_planet_jukebox.png" id="text_mario_planet_jukebox"/>',
            autoOpen: false,
            height: 375,
            width: 500,
            modal: true,
            resizable: false,
            buttons: {
                'Without Music': function() {
                    $(this).dialog('close');
                    $.cookie('autoPlay', 'no', { expires: 365 * 10 });
                },
                'With Music': function() {
                    $(this).dialog('close');
                    $.cookie('autoPlay', 'yes', { expires: 365 * 10 });
                }
            }
        });
    });

Can you spot the error? It's in the first line: the <script tag isn't closed. It should be <script type="text/javascript">

My previous suggestion still stands, however: you should enclose intra-tagged scripts in a CDATA block, or move them to a separately linked file.

That wasn't the issue here, but it would have shown the real issue faster.

In my case the problem was in not providing CA Root Certificate. I figured it out after using: https://www.ssllabs.com/ssltest/analyze.html to analyze SSL configuration.

It seems like that it is only me who are so clumsy, because i have yet to found a solution that my case required.

I am developing a multi-modular project, thus base android module configuration is extracted in single gradle script. All the concrete versions of sdks/libs are also extracted in a script.

A script containing versions looked like this:

...

ext.androidVersions = [
    compile_sdk_version     : '27',
    min_sdk_version         : '19',
    target_sdk_version      : '27',
    build_tool_version      : '27.0.3',
    application_id          : 'com.test.test',
]

...

Not accustomed to groovy syntax my eye has not spotted that the values for compile, min and target sdks were not integers but STRINGS! Therefore a compiler rightfully complained about not being able to find an sdk a version of which would match HASH STRING '27'.

So the solution would be to make sdk's versions integers: ...

ext.androidVersions = [
    compile_sdk_version     : 27,
    min_sdk_version         : 19,
    target_sdk_version      : 27,
    build_tool_version      : '27.0.3',
    application_id          : 'com.test.test',
]

...

I use swift dictionaries but convert them to and from NSDictionaries in my file manager class like so:

    func writePlist(fileName:String, myDict:Dictionary<String, AnyObject>){
        let docsDir:String = dirPaths[0] as String
        let docPath = docsDir + "/" + fileName
        let thisDict = myDict as NSDictionary
        if(thisDict.writeToFile(docPath, atomically: true)){
            NSLog("success")
        } else {
            NSLog("failure")
        }

    }
    func getPlist(fileName:String)->Dictionary<String, AnyObject>{
        let docsDir:String = dirPaths[0] as String
        let docPath = docsDir + "/" + fileName
        let thisDict = NSDictionary(contentsOfFile: docPath)
        return thisDict! as! Dictionary<String, AnyObject>
    }

This seems the least troubling way to read and write but let's the rest of my code stay as swift as possible.

You can't call it asynchronously, since there is no asynchronous property support, only async methods. As such, there are two options, both taking advantage of the fact that asynchronous methods in the CTP are really just a method that returns Task<T> or Task:

// Make the property return a Task<T>
public Task<IEnumerable> MyList
{
    get
    {
         // Just call the method
         return MyAsyncMethod();
    }
}

Or:

// Make the property blocking
public IEnumerable MyList
{
    get
    {
         // Block via .Result
         return MyAsyncMethod().Result;
    }
}

Your statement matches any string that contains a letter or digit anywhere, even if it contains other non-alphanumeric characters. Try this:

SELECT * FROM table WHERE column REGEXP '^[A-Za-z0-9]+$';

^ and $ require the entire string to match rather than just any portion of it, and + looks for 1 or more alphanumberic characters.

You could also use a named character class if you prefer:

SELECT * FROM table WHERE column REGEXP '^[[:alnum:]]+$';

The above solution is good in some scenarios but there is another scenario where this happens when you are unit testing and you try to "Debug Selected Tests" from the Test Explorer when you solution is not set to Debug.

In this case you need to change your solution from Release or whatever it is set to to Debug in this case. If this is the problem then changing "ContextSwitchDeadlock" won't really help you.

I missed this myself because the error message was so nasty I didn't check the obvious thing which was the Debug setting!

200,300, 400, 500 are all very generic. If you want generic, 400 is OK.

422 is used by an increasing number of APIs, and is even used by Rails out of the box.

No matter which status code you pick for your API, someone will disagree. But I prefer 422 because I think of '400 + text status' as too generic. Also, you aren't taking advantage of a JSON-ready parser; in contrast, a 422 with a JSON response is very explicit, and a great deal of error information can be conveyed.

Speaking of JSON response, I tend to standardize on the Rails error response for this case, which is:

{
    "errors" :
    { 
        "arg1" : ["error msg 1", "error msg 2", ...]
        "arg2" : ["error msg 1", "error msg 2", ...]
    }
}

This format is perfect for form validation, which I consider the most complex case to support in terms of 'error reporting richness'. If your error structure is this, it will likely handle all your error reporting needs.

async await is here (ES7), so you can do this kind of things very easily now.

  var i;
  var j = 10;
  for (i = 0; i < j; i++) {
    await asycronouseProcess();
    alert(i);
  }

Remember, this works only if asycronouseProcess is returning a Promise

If asycronouseProcess is not in your control then you can make it return a Promise by yourself like this

function asyncProcess() {
  return new Promise((resolve, reject) => {
    asycronouseProcess(()=>{
      resolve();
    })
  })
}

Then replace this line await asycronouseProcess(); by await asyncProcess();

Understanding Promises before even looking into async await is must (Also read about support for async await)

This is caused because there is a database running on your computer. In my case, it was an Oracle data base. By default, everytime you start your computer, the services of the database automatically starts.

Go to Start >> find Oracle or whatever data-base in the list of programms >> and manually stop the database. It appears that there is a conflict of port.

Seems you need to use JToggleButton :

JToggleButton tb = new JToggleButton("push me");
tb.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent e) {
        JToggleButton btn =  (JToggleButton) e.getSource();
        btn.setText(btn.isSelected() ? "pushed" : "push me");
    }
});

This is the only option that worked for me.

git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch *.sql'

Note: Replace *.sql with your file name or file type. Be very careful because this will go through every commit and rip this file type out.

EDIT: pay attention - after this command you will not be able to push or pull - you will see the reject of 'unrelated history' you can use 'git push --force -u origin master' to push or pull

use :

socket.Disconnect() //ok

do not use :

socket.disconnect()

You can set image as inline element using display property

<div>_x000D_
  <img style="vertical-align: middle; display: inline;" src="https://placehold.it/60x60">_x000D_
  <span style="vertical-align: middle; display: inline;">Works.</span>_x000D_
</div>

Try with the following code

View titleView = getWindow().findViewById(android.R.id.title);
    if (titleView != null) {
      ViewParent parent = titleView.getParent();
      if (parent != null && (parent instanceof View)) {
        View parentView = (View)parent;
        parentView.setBackgroundColor(Color.RED);
      }
    }

also use this link its very useful : http://nathanael.hevenet.com/android-dev-changing-the-title-bar-background/

If you already have package-lock.json file just delete it and try again.

If the yml is called docker-compose.yml it can be launched with a simple $ docker-compose up. The corresponding attachment of a terminal can be simply (consider that the yml has specified a service called myservice):

$ docker-compose exec myservice sh

However, if you are using a different yml file name, such as docker-compose-mycompose.yml, it should be launched using $ docker-compose -f docker-compose-mycompose.yml up. To attach an interactive terminal you have to specify the yml file too, just like:

$ docker-compose -f docker-compose-mycompose.yml exec myservice sh

I use this :

1-Declare a temp table variable in the script your building:

DECLARE @ShiftPeriodList TABLE(id INT NOT NULL);

2-Allocate to temp table:

IF (SOME CONDITION) 
BEGIN 
        INSERT INTO @ShiftPeriodList SELECT ShiftId FROM [hr].[tbl_WorkShift]
END
IF (SOME CONDITION2)
BEGIN
    INSERT INTO @ShiftPeriodList
        SELECT  ws.ShiftId
        FROM [hr].[tbl_WorkShift] ws
        WHERE ws.WorkShift = 'Weekend(VSD)' OR ws.WorkShift = 'Weekend(SDL)'

END

3-Reference the table when you need it in a WHERE statement :

INSERT INTO SomeTable WHERE ShiftPeriod IN (SELECT * FROM @ShiftPeriodList)

works

$('a[href*=#]').each(function () {
    $(this).attr('href', $(this).attr('href').replace('#', '#_'));
    $(this).on( "click", function() {

        var hashname = $(this).attr('href').replace('#_', '');

        if($(this).attr('href') == "#_") {
            $('html, body').animate({ scrollTop: 0 }, 300);
        }
        else {
            var target = $('a[name="' + hashname + '"], #' + hashname),
                targetOffset = target.offset().top;
            if(targetOffset >= 1) {
                $('html, body').animate({ scrollTop: targetOffset-60 }, 300);
            }
        }
    });
});

The example bellow explains how to remove bullets using a css style class. You can use , similar to css class, by identifier (#id), by parent tag, etc. The same way you can use to define a css to remove bullets from the page footer.

I've used this site as a starting point.

div.ui-menu li {
    list-style:none;
    background-image:none;
    background-repeat:none;
    background-position:0; 
}
ul
{
    list-style-type:none;
    padding:0px;
    margin:0px;
}
li
{
    background-image:url(sqpurple.gif);
    background-repeat:no-repeat;
    background-position:0px 5px; 
    padding-left:14px;
}
</style>

mysqld --initialize to initialize the data directory then mysqld &

If you had already launched mysqld& without mysqld --initialize you might have to delete all files in your data directory

You can also modify /etc/my.cnf to add a custom path to your data directory like this :

[mysqld]
...  
datadir=/path/to/directory

I don't see any problem, unless you are not managing them using a connection pool.

If you use connection pool, these connections are re-used instead of initiating new connections. so basically, leaving open connections and re-use them it is less problematic than re-creating them each time.

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

The following worked for me:

1. Open the Registry Editor (press windows key, type regedit and hit Enter) .
2. Navigate to HKEY_CURRENT_USER\Software\Microsoft\Command Processor\AutoRun and clear the values.
3. Also check HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\AutoRun.

If you're going to use a Control from another thread before showing or doing other things with the Control, consider forcing the creation of its handle within the constructor. This is done using the CreateHandle function.

In a multi-threaded project, where the "controller" logic isn't in a WinForm, this function is instrumental in Control constructors for avoiding this error.

As strings are immutable another way to do this would be to turn the string into a list, which can then be indexed and modified without any slicing trickery. However, to get the list back to a string you'd have to use .join() using an empty string.

>>> hash = '355879ACB6'
>>> hashlist = list(hash)
>>> hashlist.insert(4, '-')
>>> ''.join(hashlist)
'3558-79ACB6'

I am not sure how this compares as far as performance, but I do feel it's easier on the eyes than the other solutions. ;-)

Named instances?

You can easily use xml (from the Python standard library) to convert to a pandas.DataFrame. Here's what I would do (when reading from a file replace xml_data with the name of your file or file object):

import pandas as pd
import xml.etree.ElementTree as ET
import io

def iter_docs(author):
    author_attr = author.attrib
    for doc in author.iter('document'):
        doc_dict = author_attr.copy()
        doc_dict.update(doc.attrib)
        doc_dict['data'] = doc.text
        yield doc_dict

xml_data = io.StringIO(u'''\

etree = ET.parse(xml_data) #create an ElementTree object 
doc_df = pd.DataFrame(list(iter_docs(etree.getroot())))

If there are multiple authors in your original document or the root of your XML is not an author, then I would add the following generator:

def iter_author(etree):
    for author in etree.iter('author'):
        for row in iter_docs(author):
            yield row

and change doc_df = pd.DataFrame(list(iter_docs(etree.getroot()))) to doc_df = pd.DataFrame(list(iter_author(etree)))

Have a look at the ElementTree tutorial provided in the xml library documentation.

Redux itself is a pretty verbose library, and for such stuff you would have to use something like Redux-thunk, which will give a dispatch function, so you will be able to dispatch closing of the notification after several seconds.

I have created a library to address issues like verbosity and composability, and your example will look like the following:

import { createTile, createSyncTile } from 'redux-tiles';
import { sleep } from 'delounce';

const notifications = createSyncTile({
  type: ['ui', 'notifications'],
  fn: ({ params }) => params.data,
  // to have only one tile for all notifications
  nesting: ({ type }) => [type],
});

const notificationsManager = createTile({
  type: ['ui', 'notificationManager'],
  fn: ({ params, dispatch, actions }) => {
    dispatch(actions.ui.notifications({ type: params.type, data: params.data }));
    await sleep(params.timeout || 5000);
    dispatch(actions.ui.notifications({ type: params.type, data: null }));
    return { closed: true };
  },
  nesting: ({ type }) => [type],
});

So we compose sync actions for showing notifications inside async action, which can request some info the background, or check later whether the notification was closed manually.

ALTER TABLE mytable DROP INDEX key_Name;

This could be even better to use

void replace(string& input, const string& from, const string& to)
{
    while(true)
    {
        size_t startPosition = input.find(from);
        if(startPosition == string::npos)
            break;
        input.replace(startPosition, from.length(), to);
    }
}

You can use dir(your_object) to get the attributes and getattr(your_object, your_object_attr) to get the values

usage :

for att in dir(your_object):
    print (att, getattr(your_object,att))

_msize(array) in Windows or malloc_usable_size(array) in Linux should work for the dynamic array

Both are located within malloc.h and both return a size_t

Floats don't have a height so the containing div has a height of zero.

<div style="background-color:black; overflow:hidden;zoom:1" onmouseover="this.bgColor='white'">
<div style="float:left">hello</div>
<div style="float:right">world</div>
</div>

overflow:hidden clears the float for most browsers.

zoom:1 clears the float for IE.

Why not just using

<div [ngClass]="classes"> </div>

Here is another one:

stats = {'a':1000, 'b':3000, 'c': 100}
max(stats.iterkeys(), key=lambda k: stats[k])

The function key simply returns the value that should be used for ranking and max() returns the demanded element right away.

Newer versions of Python for Windows come with the pip package manager. (source)

pip is already installed if you're using Python 2 >=2.7.9 or Python 3 >=3.4

Use that to install packages:

cd C:\Python\Scripts\
pip.exe install <package-name>

So in your case it'd be:

pip.exe install mechanize

Xcode::Install is a simple cli software that allow you to install/select a specific Xcode version.

You can install it using gem install xcode-install
Then you will be able to install a specific version with xcversion install 9.4.1
And if you have more than one version installed, you can switch version with xcversion select 9.4

You can find more information at https://github.com/KrauseFx/xcode-install

This should help if you need a publicly exposed website but you're on a dev pc. Also to answer (I can't comment yet): "How do I post to an internal only running development server with this? – stryba "

NGROK creates a secure public URL to a local webserver on your development machine (Permanent URLs available for a fee, temporary for free).
1) Run ngrok.exe to open command line (on desktop)
2) Type ngrok.exe http 80 to start a tunnel,
3) test by browsing to the displayed web address which will forward and display the local default 80 page on your dev pc

Then use some of the tools recommended above to POST to your ngrok site ('https://xxxxxx.ngrok.io') to test your local code.

1 - Your malloc() is wrong.
2 - You are overstepping the bounds of the allocated memory
3 - You should initialize your allocated memory

Here is the program with all the changes needed. I compiled and ran... no errors or warnings.

#include <stdio.h>
#include <stdlib.h> //malloc
#include <math.h>  //sine
#include <string.h>

#define TIME 255
#define HARM 32

int main (void) {
    double sineRads;
    double sine;
    int tcount = 0;
    int hcount = 0;
    /* allocate some heap memory for the large array of waveform data */
    double *ptr = malloc(sizeof(double) * TIME);
     //memset( ptr, 0x00, sizeof(double) * TIME);  may not always set double to 0
    for( tcount = 0; tcount < TIME; tcount++ )
    {
         ptr[tcount] = 0; 
    }

    tcount = 0;
    if (NULL == ptr) {
        printf("ERROR: couldn't allocate waveform memory!\n");
    } else {
        /*evaluate and add harmonic amplitudes for each time step */
        for(tcount = 0; tcount < TIME; tcount++){
            for(hcount = 0; hcount <= HARM; hcount++){
                sineRads = ((double)tcount / (double)TIME) * (2*M_PI); //angular frequency
                sineRads *= (hcount + 1); //scale frequency by harmonic number
                sine = sin(sineRads); 
                ptr[tcount] += sine; //add to other results for this time step
            }
        }
        free(ptr);
        ptr = NULL;

To renew the development profile before it expired, I finally found a way that works for me. I boldfaced the steps I had been missing before.

Go to the Apple provisioning portal, select "Provisioning". You'll get a list "Development Provisioning Profiles" where you'll see your soon to expire profile with the label "Managed by XCode". Click the "New Profile" button on top, select the type of profile you want and create it. Wait half a minute, refresh the home screen and when it shows the new profile as "Active", switch back to XCode, go to the Organizer, select "Provisioning profiles" under "Library" in left top column. Click "Refresh" at the bottom, log in (if it asks) and the new profile appears in the list after a short while.

Now, crucially, connect your device and drag your new profile to the "Provisioning Profiles" row under the connected device in the left column.

Finally, you can clean up the old profiles from your device if you feel like it.

Note: interestingly, it seems that simply marking and deleting your provisioning profile on the iOS Provisioning Portal site causes a new fresh Team Provisioning Profile to be created. So maybe that is all that is needed. I will try that next time to see if that is enough, if so you don't need to create a profile as I described above.

Based on the comment we are removing one property from style attribute.

Here this was not affect, but when more property are used within the style it helpful.

$('#msform').css('display', '')

After this we use

$("#msform").show();

You declare

int countlines(char *filename)

to take a char * argument.

You call it like this

countlines(fp)

passing in a FILE *.

That is why you get that compile error.

You probably should change that second line to

countlines("Test.txt")

since you open the file in countlines

Your current code is attempting to open the file in two different places.

You may add a div with position:absolute within a table/div with position:relative. For example, if you want your overlay div to be shown at the bottom right of the main text div (width and height can be removed):

<div style="position:relative;width:300px;height:300px;background-color:#eef">
    <div style="position:absolute;bottom:0;right:0;width:100px;height:100px;background-color:#fee">
        I'm over you!
    </div>
    Your main text
</div>

For Eclipse

A good way to add external JARs to your Android project or any Java project is:

1. Create a folder called libs in your project's root folder
2. Copy your JAR files to the libs folder

3. Now right click on the Jar file and then select Build Path > Add to Build Path, which will create a folder called 'Referenced Libraries' within your project

   By doing this, you will not lose your libraries that are being referenced on your hard drive whenever you transfer your project to another computer.

For Android Studio

1. If you are in Android View in project explorer, change it to Project view as below

2. Right click the desired module where you would like to add the external library, then select New > Directroy and name it as 'libs'
3. Now copy the blah_blah.jar into the 'libs' folder
4. Right click the blah_blah.jar, Then select 'Add as Library..'. This will automatically add and entry in build.gradle as compile files('libs/blah_blah.jar') and sync the gradle. And you are done

Please Note : If you are using 3rd party libraries then it is better to use transitive dependencies where Gradle script automatically downloads the JAR and the dependency JAR when gradle script run.

Ex : compile 'com.google.android.gms:play-services-ads:9.4.0'

Read more about Gradle Dependency Mangement

If you have configured navigation property 1-n I would recommend you to use:

var query = db.Categories                                  // source
   .SelectMany(c=>c.CategoryMaps,                          // join
      (c, cm) => new { Category = c, CategoryMaps = cm })  // project result
   .Select(x => x.Category);                               // select result

Much more clearer to me and looks better with multiple nested joins.

If you don't want to generate and store the file on the server, are you willing to store the status, e.g. file-in-progress, file-complete? Your "waiting" page could poll the server to know when the file generation is complete. You wouldn't know for sure that the browser started the download but you'd have some confidence.

Here's mine:

set statusline=
set statusline +=%1*\ %n\ %*            "buffer number
set statusline +=%5*%{&ff}%*            "file format
set statusline +=%3*%y%*                "file type
set statusline +=%4*\ %<%F%*            "full path
set statusline +=%2*%m%*                "modified flag
set statusline +=%1*%=%5l%*             "current line
set statusline +=%2*/%L%*               "total lines
set statusline +=%1*%4v\ %*             "virtual column number
set statusline +=%2*0x%04B\ %*          "character under cursor

And here's the colors I used:

hi User1 guifg=#eea040 guibg=#222222
hi User2 guifg=#dd3333 guibg=#222222
hi User3 guifg=#ff66ff guibg=#222222
hi User4 guifg=#a0ee40 guibg=#222222

You can use this dummy plugin:

mvn archetype:generate -DgroupId=org.eclipse.m2e -DartifactId=lifecycle-mapping -Dversion=1.0.0 -DarchetypeArtifactId=maven-archetype-mojo

After generating the project install/deploy it.

JavaScript doesn't have a native StringBuffer object, so I'm assuming this is from a library you are using, or a feature of an unusual host environment (i.e. not a browser).

I doubt a library (written in JS) would produce anything faster, although a native StringBuffer object might. The definitive answer can be found with a profiler (if you are running in a browser then Firebug will provide you with a profiler for the JS engine found in Firefox).

In short:

3. Under Query Results, check Treat BINARY/VARBINARY as nonbinary character string
4. It's not mandatory to restart MySQL Workbench (you will not be prompted or informed of this requirement).*

With this setting you will be able to concatenate fields without getting blobs.

I think this applies to versions 5.2.22 and later and is the result of this MySQL bug.

Disclaimer: I don't know what the downside of this setting is - maybe when you are selecting BINARY/VARBINARY values you will see it as plain text which may be misleading and/or maybe it will hinder performance if they are large enough?

Microsoft introduced schema in version 2008. For those who didn’t know about schema, and those who didn’t care, objects were put into a default schema dbo.

dbo stands for DataBase Owner, but that’s not really important.

Think of a schema as you would a folder for files:

• You don’t need to refer to the schema if the object is in the same or default schema
• You can reference an object in a different schema by using the schema as a prefix, the way you can reference a file in a different folder.
• You can’t have two objects with the same name in a single schema, but you can in different schema
• Using schema can help you to organise a larger number of objects
• Schema can also be assigned to particular users and roles, so you can control access to who can do what.

You can always access any object from any schema.

Because dbo is the default, you normally don’t need to specify it within a single database:

SELECT * FROM customers;
SELECT * FROM dbo.customers;

mean the same thing.

I am inclined to disagree with the notion of always using the dbo. prefix, since the more you clutter your code with unnecessary detail, the harder it is to read and manage.

For the most part, you can ignore the schema. However, the schema will make itself apparent in the following situations:

1. If you view the tables in either the object navigator or in an external application, such as Microsoft Excel or Access, you will see the dbo. prefix. You can still ignore it.

2. If you reference a table in another database, you will need its full name in the form database.schema.table:

   SELECT * FROM bookshop.dbo.customers;
   

3. For historical reasons, if you write a user defined scalar function, you will need to call it with the schema prefix:

   CREATE FUNCTION tax(@amount DECIMAL(6,2) RETURNS DECIMAL(6,2) AS
   BEGIN
       RETURN @amount * 0.1;
   END;
   GO
   SELECT total, dbo.tax(total) FROM pricelist;
   

   This does not apply to other objects, such as table functions, procedures and views.

You can use schema to overcome naming conflicts. For example, if every user has a personal schema, they can create additional objects without having to fight with other users over the name.

When you want to check the condition at the beginning of the loop, simply negate the condition on a standard while loop:

while(!cond) { ... }

If you need it at the end, use a do ... while loop and negate the condition:

do { ... } while(!cond);

NPM one liner:

npm -s run env echo '$npm_package_version'

Try with a CASE in this way :

SUM(CASE 
    WHEN PaymentType = "credit card" 
    THEN TotalAmount 
    ELSE 0 
END) AS CreditCardTotal,

Should give what you are looking for ...

Are you referring to the server side or the client side?

For a client, you would want to adjust the sendTimeout attribute of a binding element. For a service, you would want to adjust the receiveTimeout attribute of a binding elemnent.

<system.serviceModel>
  <bindings>
    <netTcpBinding>
      <binding name="longTimeoutBinding"
        receiveTimeout="00:10:00" sendTimeout="00:10:00">
        <security mode="None"/>
      </binding>
    </netTcpBinding>
  </bindings>

  <services>
    <service name="longTimeoutService"
      behaviorConfiguration="longTimeoutBehavior">
      <endpoint address="net.tcp://localhost/longtimeout/"
        binding="netTcpBinding" bindingConfiguration="longTimeoutBinding" />
    </service>
....

Of course, you have to map your desired endpoint to that particular binding.

The easiest way to put the loader in the website.

HTML:

<div id="loading"></div>

CSS:

#loading {
position: fixed;
width: 100%;
height: 100vh;
background: #fff url('images/loader.gif') no-repeat center center;
z-index: 9999;
}

JQUERY:

<script>
jQuery(document).ready(function() {
    jQuery('#loading').fadeOut(3000);
});
</script>

You can also try to write different elements in different cookies. Cookies names can be set as array names and will be available to your PHP scripts as arrays but separate cookies are stored on the user's system. Consider explode() to set one cookie with multiple names and values. It is not recommended to use serialize() for this purpose, because it can result in security holes. Look at setcookie PHP function for more details

Database .NET

%lld is the standard C99 way, but that doesn't work on the compiler that I'm using (mingw32-gcc v4.6.0). The way to do it on this compiler is: %I64d

So try this:

if(e%n==0)printf("%15I64d -> %1.16I64d\n",e, 4*pi);

and

scanf("%I64d", &n);

The only way I know of for doing this in a completely portable way is to use the defines in <inttypes.h>.

In your case, it would look like this:

scanf("%"SCNd64"", &n);
//...    
if(e%n==0)printf("%15"PRId64" -> %1.16"PRId64"\n",e, 4*pi);

It really is very ugly... but at least it is portable.

wget from a linux box might also be a good option as there are switches to spider and change it's output.

EDIT: wget is also available on Windows: http://gnuwin32.sourceforge.net/packages/wget.htm

To answer the question literally (since GitHub is not in the question title), also be aware of this post over on superuser. EDIT: Answer copied here in relevant part, slightly modified for clarity in square brackets:

You're getting rejected because you're trying to delete the branch that your origin has currently "checked out".

If you have direct access to the repo, you can just open up a shell [in the bare repo] directory and use good old git branch to see what branch origin is currently on. To change it to another branch, you have to use git symbolic-ref HEAD refs/heads/another-branch.

public: for the accessibility across all the classes, just like the methods present in the interface

static: as interface cannot have an object, the interfaceName.variableName can be used to reference it or directly the variableName in the class implementing it.

final: to make them constants. If 2 classes implement the same interface and you give both of them the right to change the value, conflict will occur in the current value of the var, which is why only one time initialization is permitted.

Also all these modifiers are implicit for an interface, you dont really need to specify any of them.

flat list can be made through reduce easily.

All you need to use initializer - third argument in the reduce function.

reduce(
   lambda result, _list: result.append(
       list(set(_list)&set(c1)) 
     ) or result, 
   c2, 
   [])

Above code works for both python2 and python3, but you need to import reduce module as from functools import reduce. Refer below link for details.

• for python2

• for python3

For me, the problem was in XML migrations. I deleted all tables and sequences and it works on next bootRun

Once you have selected an element you can call click()

document.getElementById('link').click();

see: https://developer.mozilla.org/En/DOM/Element.click

I don't remember if this works on IE, but it should. I don't have a windows machine nearby.

Let me introduce you to my friend "dotglob". It turns on and off whether or not "*" includes hidden files.

$ mkdir test
$ cd test
$ touch a b c .hidden .hi .den
$ ls -a
. ..  .den  .hi .hidden a b c

$ shopt -u dotglob
$ ls *
a b c
$ for i in * ; do echo I found: $i ; done
I found: a
I found: b
I found: c

$ shopt -s dotglob
$ ls *
.den  .hi .hidden a b c
$ for i in * ; do echo I found: $i ; done
I found: .den
I found: .hi
I found: .hidden
I found: a
I found: b
I found: c

It defaults to "off".

$ shopt dotglob
dotglob         off

It is best to turn it back on when you are done otherwise you will confuse things that assume it will be off.

This article has an excellent vimrc script for handling tabs+spaces, and converting in between them.

These commands are provided:

Space2Tab Convert spaces to tabs, only in indents.

Tab2Space Convert tabs to spaces, only in indents.

RetabIndent Execute Space2Tab (if 'expandtab' is set), or Tab2Space (otherwise).

Each command accepts an argument that specifies the number of spaces in a tab column. By default, the 'tabstop' setting is used.

Source: http://vim.wikia.com/wiki/Super_retab#Script

" Return indent (all whitespace at start of a line), converted from
" tabs to spaces if what = 1, or from spaces to tabs otherwise.
" When converting to tabs, result has no redundant spaces.
function! Indenting(indent, what, cols)
  let spccol = repeat(' ', a:cols)
  let result = substitute(a:indent, spccol, '\t', 'g')
  let result = substitute(result, ' \+\ze\t', '', 'g')
  if a:what == 1
    let result = substitute(result, '\t', spccol, 'g')
  endif
  return result
endfunction

" Convert whitespace used for indenting (before first non-whitespace).
" what = 0 (convert spaces to tabs), or 1 (convert tabs to spaces).
" cols = string with number of columns per tab, or empty to use 'tabstop'.
" The cursor position is restored, but the cursor will be in a different
" column when the number of characters in the indent of the line is changed.
function! IndentConvert(line1, line2, what, cols)
  let savepos = getpos('.')
  let cols = empty(a:cols) ? &tabstop : a:cols
  execute a:line1 . ',' . a:line2 . 's/^\s\+/\=Indenting(submatch(0), a:what, cols)/e'
  call histdel('search', -1)
  call setpos('.', savepos)
endfunction

command! -nargs=? -range=% Space2Tab call IndentConvert(<line1>,<line2>,0,<q-args>)
command! -nargs=? -range=% Tab2Space call IndentConvert(<line1>,<line2>,1,<q-args>)
command! -nargs=? -range=% RetabIndent call IndentConvert(<line1>,<line2>,&et,<q-args>)

This helped me a bit more than the answers here did when I first went searching for a solution.

If you're attempting to start a SERVICE rather than activity, this worked for me:

Intent intent = new Intent();
intent.setClassName("com.example.otherapplication", "com.example.otherapplication.ServiceName");
context.startService(intent);

If you use the intent.setComponent(...) method as mentioned in other answers, you may get an "Implicit intents with startService are not safe" warning.

Update: AdoptOpenJDK has changed its name to Adoptium, as part of its move to the Eclipse Foundation.

OpenJDK ? source code
Adoptium/AdoptOpenJDK ? builds

Difference between OpenJDK and AdoptOpenJDK

The first provides source-code, the other provides builds of that source-code.

• OpenJDK is an open-source project providing source-code (not builds) of an implementation of the Java platform as defined by:
  • the Java Specifications
  • Java Specification Request (JSR) documents published by Oracle via the Java Community Process
  • JDK Enhancement Proposal (JEP) documents published by Oracle via the OpenJDK project
• AdoptOpenJDK is an organization founded by some prominent members of the Java community aimed at providing binary builds and installers at no cost for users of Java technology.

Several vendors of Java & OpenJDK

Adoptium of the Eclipse Foundation, formerly known as AdoptOpenJDK, is only one of several vendors distributing implementations of the Java platform. These include:

• Eclipse Foundation (Adoptium/AdoptOpenJDK)
• Azul Systems
• Oracle
• Red Hat / IBM
• BellSoft
• SAP
• Amazon AWS
• … and more

See this flowchart of mine to help guide you in picking a vendor for an implementation of the Java platform. Click/tap to zoom.

Another resource: This comparison matrix by Azul Systems is useful, and seems true and fair to my mind.

Here is a list of considerations and motivations to consider in choosing a vendor and implementation.

Some vendors offer you a choice of JIT technologies.

To understand more about this Java ecosystem, read Java Is Still Free

The core reason is that objects on heap are always difficult to use and manage than simple values. Writing code that are easy to read and maintain is always the first priority of any serious programmer.

Another scenario is the library we are using provides value semantics and make dynamic allocation unnecessary. Std::string is a good example.

For object oriented code however, using a pointer - which means use new to create it beforehand - is a must. In order to simplify the complexity of resource management, we have dozens of tools to make it as simple as possible, such as smart pointers. The object based paradigm or generic paradigm assumes value semantics and requires less or no new, just as the posters elsewhere stated.

Traditional design patterns, especially those mentioned in GoF book, use new a lot, as they are typical OO code.

For renaming the columns here is the simple one which will work for both Default(0,1,2,etc;) and existing columns but not much useful for a larger data sets(having many columns).

For a larger data set we can slice the columns that we need and apply the below code:

df.columns = ['new_name','new_name1','old_name']

Adding context to hopefully help provide a bit of additional clarity on this subject. To a BaSH newbie, it's sense of true/false statements is rather odd. Take the following simple examples and their results.

This statement will return "true":

foo=" "; if [ "$foo" ]; then echo "true"; else echo "false"; fi

But this will return "false":

foo=" "; if [ $foo ]; then echo "true"; else echo "false"; fi

Do you see why? The first example has a quoted "" string. This causes BaSH to treat it literally. So, in a literal sense, a space is not null. While in a non-literal sense (the 2nd example above), a space is viewed by BaSH (as a value in $foo) as 'nothing' and therefore it equates to null (interpreted here as 'false').

These statements will all return a text string of "false":

foo=; if [ $foo ]; then echo "true"; else echo "false"; fi
foo=; if [ "$foo" ]; then echo "true"; else echo "false"; fi
foo=""; if [ $foo ]; then echo "true"; else echo "false"; fi
foo=""; if [ "$foo" ]; then echo "true"; else echo "false"; fi

Interestingly, this type of conditional will always return true:

These statements will all return a result of "true":

foo=""; if [ foo ]; then echo "true"; else echo "false"; fi

Notice the difference; the $ symbol has been omitted from preceding the variable name in the conditional. It doesn't matter what word you insert between the brackets. BaSH will always see this statement as true, even if you use a word that has never been associated with a variable in the same shell before.

if [ sooperduper ]; then echo "true"; else echo "false"; fi

Likewise, defining it as an undeclared variable ensures it will always return false:

if [ $sooperduper ]; then echo "true"; else echo "false"; fi

As to BaSH it's the same as writing:

sooperduper="";if [ $sooperduper ]; then echo "true"; else echo "false"; fi

One more tip....

Brackets vs No Brackets

Making matters more confusing, these variations on the IF/THEN conditional both work, but return opposite results.

These return false:

if [ $foo ]; then echo "true"; else echo "false"; fi
if [ ! foo ]; then echo "true"; else echo "false"; fi

However, these will return a result of true:

if $foo; then echo "true"; else echo "false"; fi
if [ foo ]; then echo "true"; else echo "false"; fi
if [ ! $foo ]; then echo "true"; else echo "false"; fi

And, of course this returns a syntax error (along with a result of 'false'):

if foo; then echo "true"; else echo "false"; fi

Confused yet? It can be quite challenging to keep it straight in your head in the beginning, especially if you're used to other, higher level programming languages.

This message appears when your version of Xcode is too old for the device's version of iOS. Upgrade Xcode to the latest.

If the App Store doesn't offer an update for Xcode, upgrade to the latest Mac OS. In the past, Apple has been rather aggressive about dropping support for past versions of Mac OS X in the latest Xcode.

EDIT: yes, this error started popping up all over again. :) Xcode 7.3.1, which is the latest one that's available for MacOS 10.11 (El Capitan), doesn't support iOS 10. You need MacOS Sierra (and possibly a new Mac).

You cannot insert data because you have a quota of 0 on the tablespace. To fix this, run

ALTER USER <user> quota unlimited on <tablespace name>;

or

ALTER USER <user> quota 100M on <tablespace name>;

as a DBA user (depending on how much space you need / want to grant).

SELECT datetime('now', 'localtime');

Press Alt + v and select Toggle menu bar option.

Remember that a single = is always an assignment in C or C++.

Your test should be if ( match == 0 && k == M )you made a typo on the k == M test.

If you really mean k=M (i.e. a side-effecting assignment inside a test) you should for readability reasons code if (match == 0 && (k=m) != 0) but most coding rules advise not writing that.

BTW, your mistake suggests to ask for all warnings (e.g. -Wall option to g++), and to upgrade to recent compilers. The next GCC 4.8 will give you:

 % g++-trunk -Wall -c ederman.cc
 ederman.cc: In function ‘void foo()’:
 ederman.cc:9:30: error: lvalue required as left operand of assignment
          if ( match == 0 && k = M )
                               ^

and Clang 3.1 also tells you ederman.cc:9:30: error: expression is not assignable

So use recent versions of free compilers and enable all the warnings when using them.

this could work for you.

It worked for me

By process (in the JSF specification it's called execute) you tell JSF to limit the processing to component that are specified every thing else is just ignored.

update indicates which element will be updated when the server respond back to you request.

@all : Every component is processed/rendered.

@this: The requesting component with the execute attribute is processed/rendered.

@form : The form that contains the requesting component is processed/rendered.

@parent: The parent that contains the requesting component is processed/rendered.

With Primefaces you can even use JQuery selectors, check out this blog: http://blog.primefaces.org/?p=1867

Solution 1 (for my case): restart windows Explorer process (yes, the windows file manager).

Solution 2:

1. Close Visual Studio. Windows Logoff
2. Logon, reopen Visual Studio
3. Build as usual. It now builds and can access the problematic file.

I presume sometimes the file system or whoever is controlling it gets lost with its permissions. Before restarting the windows session, tried to kill zombie msbuild32.exe processes, restart visual studio, check none even showing the problem file on. No build configuration issues. It happens now and then. Some internal thing in Windows does not fix up, needs a restart.

To get the current directory, you can use this:

CD > tmpFile
SET /p myvar= < tmpFile
DEL tmpFile
echo test: %myvar%

It's using a temp-file though, so it's not the most pretty, but it certainly works! 'CD' puts the current directory in 'tmpFile', 'SET' loads the content of tmpFile.

Here is a solution for multiple lines with "array's":

@echo off

rem ---------
rem Obtain line numbers from the file
rem ---------

rem This is the file that is being read: You can replace this with %1 for dynamic behaviour or replace it with some command like the first example i gave with the 'CD' command.
set _readfile=test.txt

for /f "usebackq tokens=2 delims=:" %%a in (`find /c /v "" %_readfile%`) do set _max=%%a
set /a _max+=1
set _i=0
set _filename=temp.dat

rem ---------
rem Make the list
rem ---------

:makeList
find /n /v "" %_readfile% >%_filename%

rem ---------
rem Read the list
rem ---------

:readList
if %_i%==%_max% goto printList

rem ---------
rem Read the lines into the array
rem ---------
for /f "usebackq delims=] tokens=2" %%a in (`findstr /r "\[%_i%]" %_filename%`) do set _data%_i%=%%a
set /a _i+=1
goto readList

:printList
del %_filename%
set _i=1
:printMore
if %_i%==%_max% goto finished
set _data%_i%
set /a _i+=1
goto printMore

:finished

But you might want to consider moving to another more powerful shell or create an application for this stuff. It's stretching the possibilities of the batch files quite a bit.

I hope this will help to understand the relationship between .NET Standard API surface and other .NET platforms. Each interface represents a target framework and methods represents groups of APIs available on that target framework.

As per the MySQL docs: http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#sysvar_max_user_connections

 maximum range: 4,294,967,295  (e.g. 2**32 - 1)

You'd probably run out of memory, file handles, and network sockets, on your server long before you got anywhere close to that limit.

If you are using linux and gradle wrapper you can use following solution.

Add path to local.properties file:

javaHome=<path to JDK>

Add to your gradlew script file:

DIR=$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )
source $DIR/local.properties 2>/dev/null

if ! [ -z "$javaHome" ]
then
  JAVA_HOME=$javaHome
fi

In this solution, each developer can set his own JDK path. File local.properties shouldn't be included in version control system.

This worked for me from both Activity and Fragment

@Override
public void onPrepareOptionsMenu(Menu menu) {
    super.onPrepareOptionsMenu(menu);
    if (menu.findItem(R.id.action_messages) != null)
        menu.findItem(R.id.action_messages).setVisible(false);
}

I'll throw my answer into the ring as well. If you want to do this programmatically you can do the following.

final Drawable drawable = ContextCompat.getDrawable(getContext(), R.drawable.somedrawable);
final boolean isLTR = ViewCompat.LAYOUT_DIRECTION_LTR == ViewCompat.getLayoutDirection(this);
final int iconInsetPadding = getResources().getDimensionPixelSize(R.dimen.icon_padding);

final Drawable insetDrawable = new InsetDrawable(drawable, isLTR ? 0 : iconInsetPadding, 0, isLTR ? iconInsetPadding : 0, 0);

This will add the padding to the end of the drawable where end will mean left/right depending if phone is in LTR or RTL.

You definitely need to map your servlet onto some URL. If you use Java EE 6 (that means at least Servlet API 3.0) then you can annotate your servlet like

@WebServlet(name="helloServlet", urlPatterns={"/hello"})
public class HelloWorld extends HttpServlet {
     //rest of the class

Then you can just go to the localhost:8080/yourApp/hello and the value should be displayed. In case you can't use Servlet 3.0 API than you need to register this servlet into web.xml file like

<servlet>
    <servlet-name>helloServlet</servlet-name>
    <servlet-class>crunch.HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>helloServlet</servlet-name>
    <url-pattern>/hello</url-pattern>
</servlet-mapping>

As of today (27, February 2020) Oracle announced that it has published all JDBC client libraries from version 11.2.0.4 (e.g. ojdbc6) to 19.3.0 (e.g. ojdbc10) on Maven Central under the group id com.oracle.database:

Example:

<dependency>
  <groupId>com.oracle.database.jdbc</groupId>
  <artifactId>ojdbc10</artifactId>
  <version>19.3.0.0</version>
</dependency>

The normal way to control this is with git config

For example

git config --global core.autocrlf true

For details, scroll down in this link to Pro Git to the section named "core.autocrlf"

If you want to know what file this is saved in, you can run the command:

git config --global --edit

and the git global config file should open in a text editor, and you can see where that file was loaded from.

We all know that programming have endless possibilities.There are numbers of solutions available for a single problem so i think all of the above solutions are perfect and may be helpful for someone but for me this one save my day..

You just have to call the above function in onCreate Method of your MainActivity

I hope this one is also helpful for you guys.

Also read the original blog at Medium

This function will filter an object based on a list of keys, its more efficient than the previous answer as it doesn't have to use Array.filter before calling reduce. so its O(n) as opposed to O(n + filtered)

function filterObjectByKeys (object, keys) {
  return Object.keys(object).reduce((accum, key) => {
    if (keys.includes(key)) {
      return { ...accum, [key]: object[key] }
    } else {
      return accum
    }
  }, {})
}

There are two ways to Run Visual Studio as Administrator:

1. Only 1 time: For this go to startup search bar, search for Visual studio 2017 or what ever version you have, then Right click on VS and Run as Administrator.

2. Permanent or Always: For this go to startup search bar, search for visual studio, right click to it and go to properties. In the properties click on advanced button and check the Run as Administrator check box and then click on ok.

You could use np.array(list(result.items()), dtype=dtype):

import numpy as np
result = {0: 1.1181753789488595, 1: 0.5566080288678394, 2: 0.4718269778030734, 3: 0.48716683119447185, 4: 1.0, 5: 0.1395076201641266, 6: 0.20941558441558442}

names = ['id','data']
formats = ['f8','f8']
dtype = dict(names = names, formats=formats)
array = np.array(list(result.items()), dtype=dtype)

print(repr(array))

yields

array([(0.0, 1.1181753789488595), (1.0, 0.5566080288678394),
       (2.0, 0.4718269778030734), (3.0, 0.48716683119447185), (4.0, 1.0),
       (5.0, 0.1395076201641266), (6.0, 0.20941558441558442)], 
      dtype=[('id', '<f8'), ('data', '<f8')])

If you don't want to create the intermediate list of tuples, list(result.items()), then you could instead use np.fromiter:

In Python2:

array = np.fromiter(result.iteritems(), dtype=dtype, count=len(result))

In Python3:

array = np.fromiter(result.items(), dtype=dtype, count=len(result))

Why using the list [key,val] does not work:

By the way, your attempt,

numpy.array([[key,val] for (key,val) in result.iteritems()],dtype)

was very close to working. If you change the list [key, val] to the tuple (key, val), then it would have worked. Of course,

numpy.array([(key,val) for (key,val) in result.iteritems()], dtype)

is the same thing as

numpy.array(result.items(), dtype)

in Python2, or

numpy.array(list(result.items()), dtype)

in Python3.

np.array treats lists differently than tuples: Robert Kern explains:

As a rule, tuples are considered "scalar" records and lists are recursed upon. This rule helps numpy.array() figure out which sequences are records and which are other sequences to be recursed upon; i.e. which sequences create another dimension and which are the atomic elements.

Since (0.0, 1.1181753789488595) is considered one of those atomic elements, it should be a tuple, not a list.

String s = "test string (67)";

System.out.println(s.substring(s.indexOf("(")+1,s.indexOf(")")));

I have faced a similar problem, I searched everywhere online for solutions and I tried to follow them. None worked for me. These were the steps I took to the problem.

Make new repo and push the existing code again to the new repo

git init doesn’t initialize if you already have a .git/ folder in your repository. So, for your case, do -

(1) rm -rf .git/

(2) git init

(3) git remote add origin https://repository.remote.url

(4) git commit -m “Commit message”

(5) git push -f origin master

Note that all git configs like remote repositories for this repository are cleared in step 1. So, you have to set up all remote repository URLs again.

Also, take care of the -f in step 5: The remote already has some code base with n commits, and you’re trying to make all those changes into a single commit. So, force-pushing the changes to remote is necessary.

Go to your java bin directory via the cmd:

C:\Program Files\Java\jdk1.7.0_25\bin>

Now type in the below comand in your cmd:

keytool -list -v -keystore "c:\users\your_user_name\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android 

Niko Lay: How about this simple solution? :)

`<input style="background-color:white; border:1px white solid;" onclick="this.select();" id="selectable" value="http://example.com/page.htm">`

.....

Code before:

<textarea rows="20" class="codearea" style="padding:5px;" readonly="readonly">

Code after:

<textarea rows="20" class="codearea" style="padding:5px;" readonly="readonly" onclick="this.select();" id="selectable">

Just this part onclick="this.select();" id="selectable" in my code worked fine. Selects all in my code box with one mouse click.

Thanks for help Niko Lay!

To get a type that implements io.Reader from a []byte slice, you can use bytes.NewReader in the bytes package:

r := bytes.NewReader(byteData)

This will return a value of type bytes.Reader which implements the io.Reader (and io.ReadSeeker) interface.

Don't worry about them not being the same "type". io.Reader is an interface and can be implemented by many different types. To learn a little bit more about interfaces in Go, read Effective Go: Interfaces and Types.

Try this, I hope it helps you.

 if (lstCustumers.Any(cus => cus.Firstname == "John"))
 {
     //TODO CODE
 }

You can try deleting the .git file in the directory and doing everything again will fix your problem!

SQL Server drops and recreates the tables only if you:

• Add a new column
• Change the Allow Nulls setting for a column
• Change the column order in the table
• Change the column data type

Using ALTER is safer, as in case the metadata is lost while you re-create the table, your data will be lost.

To call the method, you need to qualify function with self.. In addition to that, if you want to pass a filename, add a filename parameter (or other name you want).

class MyHandler(FileSystemEventHandler):

    def on_any_event(self, event):
        srcpath = event.src_path
        print (srcpath, 'has been ',event.event_type)
        print (datetime.datetime.now())
        filename = srcpath[12:]
        self.dropbox_fn(filename) # <----

    def dropbox_fn(self, filename):  # <-----
        print('In dropbox_fn:', filename)

My case is different, it fails because of the scope of 'this':

//this fails:
$("#My-Dialog").dialog({
  ...
  close: ()=>{
    $(this).dialog("close");
  }
});

//this works:
$("#My-Dialog").dialog({
  ...
  close: function(){
    $(this).dialog("close");
  }
});

You will want to use a CONVERT() statement.

Try the following;

SELECT CONVERT(VARCHAR(10), SA.[RequestStartDate], 103) as 'Service Start Date', CONVERT(VARCHAR(10), SA.[RequestEndDate], 103) as 'Service End Date', FROM (......) SA WHERE.....

Here is another variation on the Bootstrap 4.1 Navbar with multi-level dropdown. This one uses minimal CSS for the submenu, and can be re-positioned as desired:

https://www.codeply.com/go/nG6iMAmI2X

.dropdown-submenu {
  position: relative;
}

.dropdown-submenu .dropdown-menu {
  top: 0;
  left: 100%;
  margin-top: -1px;
}

jQuery to control display of submenus:

$('.dropdown-submenu > a').on("click", function(e) {
    var submenu = $(this);
    $('.dropdown-submenu .dropdown-menu').removeClass('show');
    submenu.next('.dropdown-menu').addClass('show');
    e.stopPropagation();
});

$('.dropdown').on("hidden.bs.dropdown", function() {
    // hide any open menus when parent closes
    $('.dropdown-menu.show').removeClass('show');
});

See this answer for activating the Bootstrap 4 submenus on hover

The simple answer for this one is that you have an undeclared (null) variable. In this case it is $md5. From the comment you put this needed to be declared elsewhere in your code

$md5 = new-object -TypeName System.Security.Cryptography.MD5CryptoServiceProvider

The error was because you are trying to execute a method that does not exist.

PS C:\Users\Matt> $md5 | gm

The .ComputeHash() of $md5.ComputeHash() was the null valued expression. Typing in gibberish would create the same effect.

PowerShell by default allows this to happen as defined its StrictMode

When Set-StrictMode is off, uninitialized variables (Version 1) are assumed to have a value of 0 (zero) or $Null, depending on type. References to non-existent properties return $Null, and the results of function syntax that is not valid vary with the error. Unnamed variables are not permitted.

First you have to install a module call Serial. To do that go to the folder call Scripts which is located in python installed folder. If you are using Python 3 version it's normally located in location below,

C:\Python34\Scripts  

Once you open that folder right click on that folder with shift key. Then click on 'open command window here'. After that cmd will pop up. Write the below code in that cmd window,

pip install PySerial

and press enter.after that PySerial module will be installed. Remember to install the module u must have an INTERNET connection.

after successfully installed the module open python IDLE and write down the bellow code and run it.

import serial
# "COM11" is the port that your Arduino board is connected.set it to port that your are using        
ser = serial.Serial("COM11", 9600)
while True:
    cc=str(ser.readline())
    print(cc[2:][:-5])   

Here are two more options for 1.8.6 (or 1.9) without using enumerator:

# Fun with functional
arr = ('a'..'g').to_a
arr.zip( (2..(arr.length+2)).to_a )
#=> [["a", 2], ["b", 3], ["c", 4], ["d", 5], ["e", 6], ["f", 7], ["g", 8]]

# The simplest
n = 1
arr.map{ |c| [c, n+=1 ] }
#=> [["a", 2], ["b", 3], ["c", 4], ["d", 5], ["e", 6], ["f", 7], ["g", 8]]

Most of the answers here are either 'UnSafe" or not LittleEndian safe. BitConverter is not LittleEndian safe. So building on an example in here (see the post by PZahra) I made a LittleEndian safe version simply by reading the byte array in reverse when BitConverter.IsLittleEndian == true

void Main(){    
    Console.WriteLine(BitConverter.IsLittleEndian); 
    byte[] bytes = BitConverter.GetBytes(0xdcbaabcdfffe1608);
    //Console.WriteLine(bytes); 
    string hexStr = ByteArrayToHex(bytes);
    Console.WriteLine(hexStr);
}

public static string ByteArrayToHex(byte[] data) 
{ 
   char[] c = new char[data.Length * 2]; 
   byte b; 
  if(BitConverter.IsLittleEndian)
  {
        //read the byte array in reverse
        for (int y = data.Length -1, x = 0; y >= 0; --y, ++x) 
        { 
            b = ((byte)(data[y] >> 4)); 
            c[x] = (char)(b > 9 ? b + 0x37 : b + 0x30); 
            b = ((byte)(data[y] & 0xF)); 
            c[++x] = (char)(b > 9 ? b + 0x37 : b + 0x30); 
        }               
    }
    else
    {
        for (int y = 0, x = 0; y < data.Length; ++y, ++x) 
        { 
            b = ((byte)(data[y] >> 4)); 
            c[x] = (char)(b > 9 ? b + 0x37 : b + 0x30); 
            b = ((byte)(data[y] & 0xF)); 
            c[++x] = (char)(b > 9 ? b + 0x37 : b + 0x30); 
        }
    }
    return String.Concat("0x",new string(c));
}

It returns this:

True
0xDCBAABCDFFFE1608

which is the exact hex that went into the byte array.

There are three ways scope can be added in the directive:

1. Parent scope: This is the default scope inheritance.

The directive and its parent(controller/directive inside which it lies) scope is same. So any changes made to the scope variables inside directive are reflected in the parent controller as well. You don't need to specify this as it is the default.

2. Child scope: directive creates a child scope which inherits from the parent scope if you specify the scope variable of the directive as true.

Here, if you change the scope variables inside directive, it won't reflect in the parent scope, but if you change the property of a scope variable, that is reflected in the parent scope, as you actually modified the scope variable of the parent.

Example,

app.directive("myDirective", function(){

    return {
        restrict: "EA",
        scope: true,
        link: function(element, scope, attrs){
            scope.somvar = "new value"; //doesnot reflect in the parent scope
            scope.someObj.someProp = "new value"; //reflects as someObj is of parent, we modified that but did not override.
        }
    };
});

3. Isolated scope: This is used when you want to create the scope that does not inherit from the controller scope.

This happens when you are creating plugins as this makes the directive generic since it can be placed in any HTML and does not gets affected by its parent scope.

Now, if you don't want any interaction with the parent scope, then you can just specify scope as an empty object. like,

scope: {} //this does not interact with the parent scope in any way

Mostly this is not the case as we need some interaction with the parent scope, so we want some of the values/ changes to pass through. For this reason, we use:

1. "@"   (  Text binding / one-way binding )
2. "="   ( Direct model binding / two-way binding )
3. "&"   ( Behaviour binding / Method binding  )

@ means that the changes from the controller scope will be reflected in the directive scope but if you modify the value in the directive scope, the controller scope variable will not get affected.

@ always expects the mapped attribute to be an expression. This is very important; because to make the “@” prefix work, we need to wrap the attribute value inside {{}}.

= is bidirectional so if you change the variable in directive scope, the controller scope variable gets affected as well

& is used to bind controller scope method so that if needed we can call it from the directive

The advantage here is that the name of the variable need not be same in controller scope and directive scope.

Example, the directive scope has a variable "dirVar" which syncs with variable "contVar" of the controller scope. This gives a lot of power and generalization to the directive as one controller can sync with variable v1 while another controller using the same directive can ask dirVar to sync with variable v2.

Below is the example of usage:

The directive and controller are:

 var app = angular.module("app", []);
 app.controller("MainCtrl", function( $scope ){
    $scope.name = "Harry";
    $scope.color = "#333333";
    $scope.reverseName = function(){
     $scope.name = $scope.name.split("").reverse().join("");
    };
    $scope.randomColor = function(){
        $scope.color = '#'+Math.floor(Math.random()*16777215).toString(16);
    };
});
app.directive("myDirective", function(){
    return {
        restrict: "EA",
        scope: {
            name: "@",
            color: "=",
            reverse: "&"
        },
        link: function(element, scope, attrs){
           //do something like
           $scope.reverse(); 
          //calling the controllers function
        }
    };
});

And the html(note the differnce for @ and =):

<div my-directive
  class="directive"
  name="{{name}}"
  reverse="reverseName()"
  color="color" >
</div>

Here is a link to the blog which describes it nicely.

System.exit() can be used to run shutdown hooks before the program quits. This is a convenient way to handle shutdown in bigger programs, where all parts of the program can't (and shouldn't) be aware of each other. Then, if someone wants to quit, he can simply call System.exit(), and the shutdown hooks (if properly set up) take care of doing all necessary shutdown ceremonies such as closing files, releasing resources etc.

"This method never returns normally." means just that the method won't return; once a thread goes there, it won't come back.

Another, maybe more common, way to quit a program is to simply to reach the end of the main method. But if there are any non-daemon threads running, they will not be shut down and thus the JVM will not exit. Thus, if you have any such non-daemon threads, you need some other means (than the shutdown hooks) to shut down all non-daemon threads and release other resources. If there are no other non-daemon threads, returning from main will shut down the JVM and will call the shutdown hooks.

For some reason shutdown hooks seem to be an undervalued and misunderstood mechanism, and people are reinventing the wheel with all kind of proprietary custom hacks to quit their programs. I would encourage using shutdown hooks; it's all there in the standard Runtime that you'll be using anyway.
