When I had this problem, I had literally just forgot to fill in a parameter value in the XAML of the code.

For some reason though, the exception would send me to the CS of the WPF program rather than the XAML. No idea why.

pip install pyqt5 for python3 for ubuntu

In my Visual Studio 2019 it worked only after I set the AutoSizeColumnsMode property to None.

You were close... after your code of

WindowState = FormWindowState.Maximized;

THEN, set the form's min/max size capacity to the value once its sized out.

MinimumSize = this.Size;
MaximumSize = this.Size;

A tested and simple solution

I've been looking for an answer for this question in SO and some other sites, but one gave an answer was very complex to me and some others answers simply doesn't work correctly, so after a lot code testing I solved this puzzle.

Note: I'm using Windows 8 and my taskbar isn't on auto-hide mode.

I discovered that setting the WindowState to Normal before performing any modifications will stop the error with the not covered taskbar.

The code

I created this class that have two methods, the first enters in the "full screen mode" and the second leaves the "full screen mode". So you just need to create an object of this class and pass the Form you want to set full screen as an argument to the EnterFullScreenMode method or to the LeaveFullScreenMode method:

class FullScreen
{
    public void EnterFullScreenMode(Form targetForm)
    {
        targetForm.WindowState = FormWindowState.Normal;
        targetForm.FormBorderStyle = FormBorderStyle.None;
        targetForm.WindowState = FormWindowState.Maximized;
    }

    public void LeaveFullScreenMode(Form targetForm)
    {
        targetForm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.Sizable;
        targetForm.WindowState = FormWindowState.Normal;
    }
}

Usage example

    private void fullScreenToolStripMenuItem_Click(object sender, EventArgs e)
    {
        FullScreen fullScreen = new FullScreen();

        if (fullScreenMode == FullScreenMode.No)  // FullScreenMode is an enum
        {
            fullScreen.EnterFullScreenMode(this);
            fullScreenMode = FullScreenMode.Yes;
        }
        else
        {
            fullScreen.LeaveFullScreenMode(this);
            fullScreenMode = FullScreenMode.No;
        }
    }

I have placed this same answer on another question that I'm not sure if is a duplicate or not of this one. (Link to the other question: How do I make a WinForms app go Full Screen)

I was trying Viachaslau's answer since I like the idea of not removing the button but disabling it, but for some reason it did not always work: the close button was still enabled but no errors whatsoever.

This on the other hand always worked (error checking omitted):

[DllImport( "user32.dll" )]
private static extern IntPtr GetSystemMenu( IntPtr hWnd, bool bRevert );
[DllImport( "user32.dll" )]
private static extern bool EnableMenuItem( IntPtr hMenu, uint uIDEnableItem, uint uEnable );

private const uint MF_BYCOMMAND = 0x00000000;
private const uint MF_GRAYED = 0x00000001;
private const uint SC_CLOSE = 0xF060;
private const int WM_SHOWWINDOW = 0x00000018;

protected override void OnSourceInitialized( EventArgs e )
{
  base.OnSourceInitialized( e );
  var hWnd = new WindowInteropHelper( this );
  var sysMenu = GetSystemMenu( hWnd.Handle, false );
  EnableMenuItem( sysMenu, SC_CLOSE, MF_BYCOMMAND | MF_GRAYED );
}

And for the menustrip-question, try set

MenuStrip1.Parent = Nothing

when in fullscreen mode, it should then disapear.

And when exiting fullscreenmode, reset the menustrip1.parent to the form again and the menustrip will be normal again.

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

<Window x:Class="TCI.Indexer.UI.Operacao"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:tci="clr-namespace:TCI.Indexer.UI.Controles"
Title=" " MinHeight="550" MinWidth="675" Loaded="Load" 
ResizeMode="NoResize" WindowStyle="None" WindowStartupLocation="CenterScreen" 
WindowState="Maximized" Focusable="True" x:Name="windowOperacao">

<Canvas x:Name="canv">
    <Grid>
        <tci:Status x:Name="ucStatus" Width="{Binding ElementName=canv
                                                    , Path=ActualWidth}" 
                                      Height="{Binding ElementName=canv
                                                    , Path=ActualHeight}"/> 
        <!-- the control which I want to stretch in width -->
    </Grid>
</Canvas>

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

If you use the JMX provided history of GC runs you can use the same before/after numbers, you just dont have to force a GC.

You just need to keep in mind that those GC runs (typically one for old and one for new generation) are not on regular intervalls, so you need to extract the starttime as well for plotting (or you plot against a sequence number, for most practical purposes that would be enough for plotting).

For example on Oracle HotSpot VM with ParNewGC, there is a JMX MBean called java.lang:type=GarbageCollector,name=PS Scavenge, it has a attribute LastGCInfo, it returns a CompositeData of the last YG scavenger run. It is recorded with duration, absolute startTime and memoryUsageBefore and memoryUsageAfter.

Just use a timer to read that attribute. Whenever a new startTime shows up you know that it describes a new GC event, you extract the memory information and keep polling for the next update. (Not sure if a AttributeChangeNotification somehow can be used.)

Tip: in your timer you might measure the distance to the last GC run, and if that is too long for the resulution of your plotting, you could invoke System.gc() conditionally. But I would not do that in a OLTP instance.

If it shows an error on the first run only, it's probably because you haven't sent any POST data. You should check for POST variables before working with them. Undefined, null, empty array, empty string, etc. are all considered false; and when PHP auto-casts that false boolean value to an integer or a float, it becomes zero. That's what happens with your variables, they are not set on the first run, and thus are treated as zeroes.

10 / $unsetVariable

becomes

10 / 0

Bottom line: check if your inputs exist and if they are valid before doing anything with them, also enable error reporting when you're doing local work as it will save you a lot of time. You can enable all errors to be reported like this: error_reporting(E_ALL);

To fix your specific problem: don't do any calculations if there's no input from your form; just show the form instead.

Posting a string:

curl -d "String to post" "http://www.example.com/target"

Posting the contents of a file:

curl -d @soap.xml "http://www.example.com/target"

You can use following methods to get current date in milliseconds.

[[NSDate date] timeIntervalSince1970];

OR

double CurrentTime = CACurrentMediaTime(); 

Source: iPhone: How to get current milliseconds?

It depends on which Platform you work. To get the correct result use -

System.getProperty("line.separator")

Calendar API

From that you can see that calendar.month_name[3] would return March, and the array index of 0 is the empty string, so there's no need to worry about zero-indexing either.

Also, you do not have to use nested CASEs. You can use several WHEN-THEN lines and the ELSE line is also optional eventhough I recomend it

CASE 
   WHEN [condition.1] THEN [expression.1]
   WHEN [condition.2] THEN [expression.2]
   ...
   WHEN [condition.n] THEN [expression.n]
   ELSE [expression] 
END

As of 10. July 2017, the issue of Bootstrap 4 support with bootstrap-select is still open. In the open issue, there are some ad-hoc solutions which you could try with your project.

Or you could use a library like Select2 and add a theme to match Bootstrap 4. Here is an example: Select 2 with Bootstrap 4 (disclaimer: I'm not the author of this blog post and I haven't verified if this still works with the all versions of Bootstrap 4).

In Java script you declare array as below:

var array=[];
array.push();

and for arraylist or object or array you have to use json; and Serialize it using json by using following code:

 var serializedMyObj = JSON.stringify(myObj);

The foreign keys in your schema (on Account_Name and Account_Type) do not require any special treatment or syntax. Just declare two separate foreign keys on the Customer table. They certainly don't constitute a composite key in any meaningful sense of the word.

There are numerous other problems with this schema, but I'll just point out that it isn't generally a good idea to build a primary key out of multiple unique columns, or columns in which one is functionally dependent on another. It appears that at least one of these cases applies to the ID and Name columns in the Customer table. This allows you to create two rows with the same ID (different name), which I'm guessing you don't want to allow.

Props to @Nick-Harrison for his answer:

$("input[data-val-length-max]").each(function (index, element) {
var length = parseInt($(this).attr("data-val-length-max"));
$(this).prop("maxlength", length);
});

I was wondering what the parseInt() is for there? I've simplified it to this with no problems...

$("input[data-val-length-max]").each(function (index, element) {
    element.setAttribute("maxlength", element.getAttribute("data-val-length-max"))
});

I would have commented on Nicks answer but don't have enough rep yet.

use for each loop...

ArrayList<Character> al = new ArrayList<>();    
String input="hello";

for (int i = 0; i < input.length(); i++){
    al.add(input.charAt(i));
}

for (Character ch : al) {               
    System.Out.println(ch);             
}

! pip install --user <package>

The ! tells the notebook to execute the cell as a shell command.

This happened to me, I tried all the possible solutions with no luck!

Finaly I realized that the problem was with Jupyter notebook environment, not with sklearn!

I solved the problem by re-installing Jupyter at the same environment as sklearn

the command is: conda install -c anaconda ipython. Done...

        const arr = ['1', '2', '3'];

         // Old way
        const cloneArr = arr.slice();

        // ES6 way
        const cloneArrES6 = [...arr];

// But problem with 3rd approach is that if you are using muti-dimensional 
 // array, then only first level is copied

        const nums = [
              [1, 2], 
              [10],
         ];

        const cloneNums = [...nums];

// Let's change the first item in the first nested item in our cloned array.

        cloneNums[0][0] = '8';

        console.log(cloneNums);
           // [ [ '8', 2 ], [ 10 ], [ 300 ] ]

        // NOOooo, the original is also affected
        console.log(nums);
          // [ [ '8', 2 ], [ 10 ], [ 300 ] ]

So, in order to avoid these scenarios to happen, use

        const arr = ['1', '2', '3'];

        const cloneArr = Array.from(arr);

If you need a button like this:

You can use RaisedButton and use the child property to do this. You need to add a Row and inside row you can add a Text widget and an Icon Widget to achieve this. If you want to use png image, you can use similar widget to achieve this.

RaisedButton(
    onPressed: () {},
    color: Theme.of(context).accentColor,
    child: Padding(
      padding: EdgeInsets.fromLTRB(
          SizeConfig.safeBlockHorizontal * 5,
          0,
          SizeConfig.safeBlockHorizontal * 5,
          0),
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: <Widget>[
          Text(
            'Continue',
            style: TextStyle(
              fontSize: 20,
              fontWeight: FontWeight.w700,
              color: Colors.white,
            ),
          ),
          Icon(
            Icons.arrow_forward,
            color: Colors.white,
          )
        ],
      ),
    ),
  ),

var dictionary = (from x in y 
                  select new SomeClass
                  {
                      prop1 = value1,
                      prop2 = value2
                  }
                  ).ToDictionary(item => item.prop1);

That's assuming that SomeClass.prop1 is the desired Key for the dictionary.

Just change the url to http://localhost instead of localhost. If you open the html file from local, you should create a local server to serve that html file, the simplest way is using Web Server for Chrome. That will fix the issue.

You must first convert your timestamps to Python datetime objects (use datetime.strptime). Then use date2num to convert the dates to matplotlib format.

Plot the dates and values using plot_date:

dates = matplotlib.dates.date2num(list_of_datetimes)
matplotlib.pyplot.plot_date(dates, values)

You can simply use | filter:yourFunction:arg

<div ng-repeat="group in groups | filter:weDontLike:group">...</div>

And in js

$scope.weDontLike = function(group) {
//here your condition/criteria
return !!group 
}

What about something like this?

var arr = [];

$('[id^=event]', response).each(function(){
    arr.push($(this).html());
});

The [attr^=selector] selector matches elements on which the attr attribute starts with the given string, that way you don't care about the numbers after "event".

You can get the column name details from sys.columns table

Try the following query:

SELECT * FROM SYS.COLUMNS 
WHERE object_id = OBJECT_ID('dbo.TableName') 
AND [Name] <> 'ColumnName'

DECLARE @sql as VARCHAR(8000)
SET @sql = 'SELECT '

SELECT @sql += [Name] + ', ' FROM SYS.COLUMNS 
WHERE object_id = OBJECT_ID('dbo.TableName') 
AND [Name] <> 'ColumnName'

SELECT @sql += ' FROM Dbo.TableName'

EXEC(@sql)

You can either add or replace fragment in your activity. Create a FrameLayout in activity layout xml file.

Then do this in your activity to add fragment:

FragmentManager manager = getFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.add(R.id.container,YOUR_FRAGMENT_NAME,YOUR_FRAGMENT_STRING_TAG);
transaction.addToBackStack(null);
transaction.commit();

And to replace fragment do this:

FragmentManager manager = getFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.container,YOUR_FRAGMENT_NAME,YOUR_FRAGMENT_STRING_TAG);
transaction.addToBackStack(null);
transaction.commit();

See Android documentation on adding a fragment to an activity or following related questions on SO:

Difference between add(), replace(), and addToBackStack()

Basic difference between add() and replace() method of Fragment

For Full like you can user :

$this->db->like('title',$query);

For %$query you can use

$this->db->like('title', $query, 'before');

and for $query% you can use

$this->db->like('title', $query, 'after');

vannilla Nodejs callback

function fileExists(path, cb){
  return fs.access(path, fs.constants.F_OK,(er, result)=> cb(!err && result)) //F_OK checks if file is visible, is default does no need to be specified.
}

the docs say you should use access() as a replacement for deprecated exists()

Nodejs with build in promise (node 7+)

function fileExists(path, cb){
  return new Promise((accept,deny) => 
    fs.access(path, fs.constants.F_OK,(er, result)=> cb(!err && result))
  );
}

Popular javascript framework

fs-extra

var fs = require('fs-extra')
await fs.pathExists(filepath)

As you see much simpler. And the advantage over promisify is that you have complete typings with this package (complete intellisense/typescript)! Most of the cases you will have already included this library because (+-10.000) other libraries depend on it.

You are correct about the action used in Intent but it's not the only thing you have to do. You'll also have to add

startActivityForResult(intent, YOUR_REQUEST_CODE);

To get it all done and retrieve the actual picture you could check the following thread.

import datetime
a = datetime.datetime.today().year

or even (as Lennart suggested)

a = datetime.datetime.now().year

or even

a = datetime.date.today().year

no , there is nothing similar IndexOf for Dictionary although you can make use of ContainsKey method to get whether a key belongs to dictionary or not

You need to read from the configuration section manually before your code returns a JsonResult object. Simply read from web.config in single line:

        var jsonResult = Json(resultsForAjaxUI);
        jsonResult.MaxJsonLength = (ConfigurationManager.GetSection("system.web.extensions/scripting/webServices/jsonSerialization") as System.Web.Configuration.ScriptingJsonSerializationSection).MaxJsonLength;
        return jsonResult;

Be sure you defined configuration element in web.config

You must to wrap your following code into a block (Either method or static).

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("What is your name?");
String name = in.readLine(); ;
System.out.println("Hello " + name);

Without a block you can only declare variables and more than that assign them a value in single statement.

For method main() will be best choice for now:

public class details {
    public static void main(String[] args){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

or If you want to use static block then...

public class details {
    static {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

or if you want to build another method then..

public class details {
    public static void main(String[] args){
        myMethod();
    }
    private static void myMethod(){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

Also worry about exception due to BufferedReader .

I am sure It working fine for you

This will surely solve your problem.

An overview of the many helpful existing answers, complemented with explanations:

^{The examples here use a simplified use case: replace the word 'foo' with 'bar' in the first matching line only.
Due to use of ANSI C-quoted strings ($'...') to provide the sample input lines, bash, ksh, or zsh is assumed as the shell.}

GNU sed only:

Ben Hoffstein's anwswer shows us that GNU provides an extension to the POSIX specification for sed that allows the following 2-address form: 0,/re/ (re represents an arbitrary regular expression here).

0,/re/ allows the regex to match on the very first line also. In other words: such an address will create a range from the 1st line up to and including the line that matches re - whether re occurs on the 1st line or on any subsequent line.

• Contrast this with the POSIX-compliant form 1,/re/, which creates a range that matches from the 1st line up to and including the line that matches re on subsequent lines; in other words: this will not detect the first occurrence of an re match if it happens to occur on the 1st line and also prevents the use of shorthand // for reuse of the most recently used regex (see next point).¹

If you combine a 0,/re/ address with an s/.../.../ (substitution) call that uses the same regular expression, your command will effectively only perform the substitution on the first line that matches re.
sed provides a convenient shortcut for reusing the most recently applied regular expression: an empty delimiter pair, //.

$ sed '0,/foo/ s//bar/' <<<$'1st foo\nUnrelated\n2nd foo\n3rd foo' 
1st bar         # only 1st match of 'foo' replaced
Unrelated
2nd foo
3rd foo

A POSIX-features-only sed such as BSD (macOS) sed (will also work with GNU sed):

Since 0,/re/ cannot be used and the form 1,/re/ will not detect re if it happens to occur on the very first line (see above), special handling for the 1st line is required.

MikhailVS's answer mentions the technique, put into a concrete example here:

$ sed -e '1 s/foo/bar/; t' -e '1,// s//bar/' <<<$'1st foo\nUnrelated\n2nd foo\n3rd foo'
1st bar         # only 1st match of 'foo' replaced
Unrelated
2nd foo
3rd foo

Note:

• The empty regex // shortcut is employed twice here: once for the endpoint of the range, and once in the s call; in both cases, regex foo is implicitly reused, allowing us not to have to duplicate it, which makes both for shorter and more maintainable code.

• POSIX sed needs actual newlines after certain functions, such as after the name of a label or even its omission, as is the case with t here; strategically splitting the script into multiple -e options is an alternative to using an actual newlines: end each -e script chunk where a newline would normally need to go.

1 s/foo/bar/ replaces foo on the 1st line only, if found there. If so, t branches to the end of the script (skips remaining commands on the line). (The t function branches to a label only if the most recent s call performed an actual substitution; in the absence of a label, as is the case here, the end of the script is branched to).

When that happens, range address 1,//, which normally finds the first occurrence starting from line 2, will not match, and the range will not be processed, because the address is evaluated when the current line is already 2.

Conversely, if there's no match on the 1st line, 1,// will be entered, and will find the true first match.

The net effect is the same as with GNU sed's 0,/re/: only the first occurrence is replaced, whether it occurs on the 1st line or any other.

NON-range approaches

potong's answer demonstrates loop techniques that bypass the need for a range; since he uses GNU sed syntax, here are the POSIX-compliant equivalents:

Loop technique 1: On first match, perform the substitution, then enter a loop that simply prints the remaining lines as-is:

$ sed -e '/foo/ {s//bar/; ' -e ':a' -e '$!{n;ba' -e '};}' <<<$'1st foo\nUnrelated\n2nd foo\n3rd foo'
1st bar
Unrelated
2nd foo
3rd foo

Loop technique 2, for smallish files only: read the entire input into memory, then perform a single substitution on it.

$ sed -e ':a' -e '$!{N;ba' -e '}; s/foo/bar/' <<<$'1st foo\nUnrelated\n2nd foo\n3rd foo'
1st bar
Unrelated
2nd foo
3rd foo

^{1 1.61803 provides examples of what happens with 1,/re/, with and without a subsequent s//:}

• sed '1,/foo/ s/foo/bar/' <<<$'1foo\n2foo' yields $'1bar\n2bar'; i.e., both lines were updated, because line number 1 matches the 1st line, and regex /foo/ - the end of the range - is then only looked for starting on the next line. Therefore, both lines are selected in this case, and the s/foo/bar/ substitution is performed on both of them.
• sed '1,/foo/ s//bar/' <<<$'1foo\n2foo\n3foo' fails: with sed: first RE may not be empty (BSD/macOS) and sed: -e expression #1, char 0: no previous regular expression (GNU), because, at the time the 1st line is being processed (due to line number 1 starting the range), no regex has been applied yet, so // doesn't refer to anything.
  With the exception of GNU sed's special 0,/re/ syntax, any range that starts with a line number effectively precludes use of //.

You use this signature: (in c#) static void Main(string[] args)

This article may help to explain the role of the main function in programming as well: http://en.wikipedia.org/wiki/Main_function_(programming)

Here is a little example for you:

class Program
{
    static void Main(string[] args)
    {
        bool doSomething = false;

        if (args.Length > 0 && args[0].Equals("doSomething"))
            doSomething = true;

        if (doSomething) Console.WriteLine("Commandline parameter called");
    }
}

Just use list comprehension.

Half line solution:

common_elements = [x for x in list1 if x in list2]

If that helped, consider upvoting my answer.

This trick supposed to prevent v = null kind of typos.

But Java allows only boolean expressions as if() conditions so that trick does not make much sense, compiler will find those typos anyway.

It is still valuable trick for C/C++ code though.

A thread is something like some branch. Multi-branched means when there are at least two branches. If the branches are reduced, then the minimum remains one. This one is although like the branches removed, but in general we do not consider it branch.

Similarly when there are at least two threads we call it multi-threaded program. If the threads are reduced, the minimum remains one. Hello program is a single threaded program, but no one needs to know multi-threading to write or run it.

In simple words when a program is not said to be having threads, it means that the program is not a multi-threaded program, more over in true sense it is a single threaded program, in which YOU CAN put your code as if it is multi-threaded.

Below a useless code is given, but it will suffice to do away with your some confusions about Runnable. It will print "Hello World".

class NamedRunnable implements Runnable {

    public void run() { // The run method prints a message to standard output.
        System.out.println("Hello World");
    }

    public static void main(String[]arg){ 
        NamedRunnable namedRunnable = new NamedRunnable( );
        namedRunnable.run();
    } 
}

server {
  server_name example.com;
  root /path/to/root;
  location / {
    # bla bla
  }
  location /demo {
    alias /path/to/root/production/folder/here;
  }
}

If you need to use try_files inside /demo you'll need to replace alias with a root and do a rewrite because of the bug explained here

If, like me, you are trying to use GETDATE() within an expression and have the seemingly unreasonable requirement (SSIS/SSDT seems very much a work in progress to me, and not a polished offering) of wanting that date to get inserted into SQL Server as a valid date (type = datetime), then I found this expression to work:

@[User::someVar] = (DT_WSTR,4)YEAR(GETDATE()) + "-"  + RIGHT("0" + (DT_WSTR,2)MONTH(GETDATE()), 2) + "-"  + RIGHT("0" + (DT_WSTR,2)DAY( GETDATE()), 2) + " " + RIGHT("0" + (DT_WSTR,2)DATEPART("hh", GETDATE()), 2) + ":" + RIGHT("0" + (DT_WSTR,2)DATEPART("mi", GETDATE()), 2) + ":" + RIGHT("0" + (DT_WSTR,2)DATEPART("ss", GETDATE()), 2)

I found this code snippet HERE

A Runnable is basically a type of class (Runnable is an Interface) that can be put into a thread, describing what the thread is supposed to do.

The Runnable Interface requires of the class to implement the method run() like so:

public class MyRunnableTask implements Runnable {
     public void run() {
         // do stuff here
     }
}

And then use it like this:

Thread t = new Thread(new MyRunnableTask());
t.start();

If you did not have the Runnable interface, the Thread class, which is responsible to execute your stuff in the other thread, would not have the promise to find a run() method in your class, so you could get errors. That is why you need to implement the interface.

Advanced: Anonymous Type

Note that you do not need to define a class as usual, you can do all of that inline:

Thread t = new Thread(new Runnable() {
    public void run() {
        // stuff here
    }
});
t.start();

This is similar to the above, only you don't create another named class.

Install

• Ctrl+P, write ext install npm script runner
• Restart VS Code

Use (two ways)

• Ctrl+R Shift+R
• Ctrl+P, write >npm, select run script, select the desired task

Update: Since version 1.3 Visual Studio Code has integrated terminal. To open it, use any of these methods:

• Use the Ctrl+` keyboard shortcut.
• Use the View | Toggle Integrated Terminal menu command.
• From the Command Palette (Ctrl+Shift+P), use the View:Toggle Integrated Terminal command.

Most are saying killall -9 dart but nobody mentioned pkill -f dart which worked for me.

The difference between the 2 is explained here.

After pruning, you can get the list of remote branches with git branch -r. The list of branches with their remote tracking branch can be retrieved with git branch -vv. So using these two lists you can find the remote tracking branches that are not in the list of remotes.

This line should do the trick (requires bash or zsh, won't work with standard Bourne shell):

git branch -r | awk '{print $1}' | egrep -v -f /dev/fd/0 <(git branch -vv | grep origin) | awk '{print $1}' | xargs git branch -d

This string gets the list of remote branches and passes it into egrep through the standard input. And filters the branches that have a remote tracking branch (using git branch -vv and filtering for those that have origin) then getting the first column of that output which will be the branch name. Finally passing all the branch names into the delete branch command.

Since it is using the -d option, it will not delete branches that have not been merged into the branch that you are on when you run this command.

Also remember that you'll need to run git fetch --prune first, otherwise git branch -r will still see the remote branches.

Because the first option is already selected, the change event is never fired. Add an empty value as the first one and check for empty in the location assignment.

Here's an example:

https://jsfiddle.net/bL5sq/

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">_x000D_
  <option value="">Select...</option>_x000D_
  <option value="https://google.com">Google</option>_x000D_
  <option value="https://yahoo.com">Yahoo</option>_x000D_
</select>

WITH NOCHECK is used as well when one has existing data in a table that doesn't conform to the constraint as defined and you don't want it to run afoul of the new constraint that you're implementing...

Just like you used echo to print a webpage. You could use also do the same with redirecting.

print("<script type=\"text/javascript\">location.href=\"urlHere\"</script>")

Hmmm I bet that in some previous lines you have something like:

list = set(something)

Am I wrong ?

The method that you want to run must be a ThreadStart Delegate. Please consult the Thread documentation on MSDN. Note that you can sort of create your two-parameter start with a closure. Something like:

var t = new Thread(() => Startup(port, path));

Note that you may want to revisit your method accessibility. If I saw a class starting a thread on its own public method in this manner, I'd be a little surprised.

You're probably returning an object that's on the stack. That is, return_Object() probably looks like this:

Object& return_Object()
{
    Object object_to_return;
    // ... do stuff ...

    return object_to_return;
}

If this is what you're doing, you're out of luck - object_to_return has gone out of scope and been destructed at the end of return_Object, so myObject refers to a non-existent object. You either need to return by value, or return an Object declared in a wider scope or newed onto the heap.

From your log its clear that numpy package is missing. As mention in the PyPI package:

The SciPy library depends on NumPy, which provides convenient and fast N-dimensional array manipulation.

So, try installing numpy package for python as you did with scipy.

Check the Java API for List.
The get(int index) method is declared to throw only the IndexOutOfBoundException which extends RuntimeException.
You are trying to tell Mockito to throw an exception SomeException() that is not valid to be thrown by that particular method call.

To clarify further.
The List interface does not provide for a checked Exception to be thrown from the get(int index) method and that is why Mockito is failing.
When you create the mocked List, Mockito will use the definition of List.class to creates its mock.

The behavior you are specifying with the when(list.get(0)).thenThrow(new SomeException()) doesn't match the method signature in List API, because get(int index) method does not throw SomeException() so Mockito fails.

If you really want to do this, then have Mockito throw a new RuntimeException() or even better throw a new ArrayIndexOutOfBoundsException() since the API specifies that that is the only valid Exception to be thrown.

below is the alternative to replace string ignoring character case

String thisString = "hello world"; 
String replaceString = "World";

//thisString.Replace("World", "csharp"); 
//below is the alternative to replace string ignoring character case

int start = StringUtils.indexOfIgnoreCase(thisString,replaceString);
String searchKey = thisString.substring(start, start+replaceString.length());
thisString= thisString.replaceAll(searchKey ,replaceString );
System.out.println(thisString);

//prints hello World

From the Linux manual page:

h      A  following  integer conversion corresponds to a short int or unsigned short int argument, or a fol-
       lowing n conversion corresponds to a pointer to a short int argument.

So to print an unsigned short integer, the format string should be "%hu".

since no one else did, I'll add py3k versions:

>>> d = { 'a': 1, 'b': 2, 'c': 3 }
>>> list(d.items())
[('a', 1), ('c', 3), ('b', 2)]
>>> [(v, k) for k, v in d.items()]
[(1, 'a'), (3, 'c'), (2, 'b')]

You can wrap all tasks which can fail in block, and use ignore_errors: yes with that block.

tasks:
  - name: ls
    command: ls -la
  - name: pwd
    command: pwd

  - block:
    - name: ls non-existing txt file
      command: ls -la no_file.txt
    - name: ls non-existing pic
      command: ls -la no_pic.jpg
    ignore_errors: yes

As mentionned in comments: you need a way to send your static files to the client. This can be achieved with a reverse proxy like Nginx, or simply using express.static().

Put all your "static" (css, js, images) files in a folder dedicated to it, different from where you put your "views" (html files in your case). I'll call it static for the example. Once it's done, add this line in your server code:

app.use("/static", express.static('./static/'));

This will effectively serve every file in your "static" folder via the /static route.

Querying your index.js file in the client thus becomes:

<script src="static/index.js"></script>

Try this code

$('#frmStudent').on('submit', function() {
  $(#StudentModal).on('hide.bs.modal', function (e) {
    e.preventDefault();
  })
});

My IDE is NetBeans. I put log4j.property file as shown in the pictures

Root

Web

WEB-INF

To use this property file you should to write this code:

package example;

import java.io.File;
import org.apache.log4j.PropertyConfigurator;
import org.apache.log4j.Logger;
import javax.servlet.*;
public class test {

public static ServletContext context;
static Logger log = Logger.getLogger("example/test");

public test() {

        String homeDir = context.getRealPath("/");
        File propertiesFile = new File(homeDir, "WEB-INF/log4j.properties");
        PropertyConfigurator.configure(propertiesFile.toString());
        log.info("This is a test");
    }
}

You can define static ServletContext context from another JSP file. Example:

test.context = getServletContext(); 
test sample = new test(); 

Now you can use log4j.property file in your projects.

do.call(rbind, lapply(split(group,as.factor(group$Subject)), function(x) {return(x[which.max(x$pt),])}))

Using Base R

The first example demonstrates event delegation. The event handler is bound to an element higher up the DOM tree (in this case, the document) and will be executed when an event reaches that element having originated on an element matching the selector.

This is possible because most DOM events bubble up the tree from the point of origin. If you click on the #id element, a click event is generated that will bubble up through all of the ancestor elements (side note: there is actually a phase before this, called the 'capture phase', when the event comes down the tree to the target). You can capture the event on any of those ancestors.

The second example binds the event handler directly to the element. The event will still bubble (unless you prevent that in the handler) but since the handler is bound to the target, you won't see the effects of this process.

By delegating an event handler, you can ensure it is executed for elements that did not exist in the DOM at the time of binding. If your #id element was created after your second example, your handler would never execute. By binding to an element that you know is definitely in the DOM at the time of execution, you ensure that your handler will actually be attached to something and can be executed as appropriate later on.

    val = params[i].split("=");
    if (val[0] == paramName) {
      return unescape(val[1]);
    }
  }
  return null;
}

This is a way to create tables dynamically using T-SQL stored procedures:

declare @cmd nvarchar(1000), @MyTableName nvarchar(100);
set @MyTableName = 'CustomerDetails';
set @cmd = 'CREATE TABLE dbo.' + quotename(@MyTableName, '[') + '(ColumnName1 int not null,ColumnName2 int not null);';

Execute it as:

exec(@cmd);

An Eclipse plugin that works reasonably well is Unused Code Detector.

It processes an entire project, or a specific file and shows various unused/dead code methods, as well as suggesting visibility changes (i.e. a public method that could be protected or private).

If you're happy with the Effective Java implementation recommended by dmeister, you can use a library call instead of rolling your own:

@Override
public int hashCode() {
    return Objects.hashCode(this.firstName, this.lastName);
}

This requires either Guava (com.google.common.base.Objects.hashCode) or the standard library in Java 7 (java.util.Objects.hash) but works the same way.

Unless your click is firing some kind of ajax call to populate your list, you don't actually need to execute the click.

Just find the element and then enumerate the options, selecting the option(s) you want.

The question is specific to SQL Server, but I would like to extend Martin Smith's answer.

SQL:2003 standard allows to define multiple values for simple case expression:

SELECT CASE c.Number
          WHEN '1121231','31242323' THEN 1
          WHEN '234523','2342423' THEN 2
       END AS Test
FROM tblClient c;

It is optional feature: Comma-separated predicates in simple CASE expression“ (F263).

Syntax:

CASE <common operand>
     WHEN <expression>[, <expression> ...] THEN <result>
    [WHEN <expression>[, <expression> ...] THEN <result>
     ...]
    [ELSE <result>]
END

As for know I am not aware of any RDBMS that actually supports that syntax.

Stopping the thread in midway using Thread.stop() is not a good practice. More appropriate way is to make the thread return programmatically. Let the Runnable object use a shared variable in the run() method. Whenever you want the thread to stop, use that variable as a flag.

EDIT: Sample code

class MyThread implements Runnable{
    
    private Boolean stop = false;
    
    public void run(){
        
        while(!stop){
            
            //some business logic
        }
    }
    public Boolean getStop() {
        return stop;
    }

It helps me!

there are lots of compression methods that work recursively command line and its good to know who the end audience is.

i.e. if it is to be sent to someone running windows then zip would probably be best:

zip -r file.zip folder_to_zip

unzip filenname.zip

for other linux users or your self tar is great

tar -cvzf filename.tar.gz folder

tar -cvjf filename.tar.bz2 folder  # even more compression

#change the -c to -x to above to extract

One must be careful with tar and how things are tarred up/extracted, for example if I run

cd ~
tar -cvzf passwd.tar.gz /etc/passwd
tar: Removing leading `/' from member names
/etc/passwd


pwd

/home/myusername

tar -xvzf passwd.tar.gz

this will create /home/myusername/etc/passwd

unsure if all versions of tar do this:

 Removing leading `/' from member names

I also encountered a similar problem. I run Ubuntu 11.04 on VMware on a Windows 7 host OS. Virtual machines can't expose the physical wireless cards. All of that is using a virtualization layer.

Addition to third answer: If you're using non-english Windows, you can find "Credentials Manager" through "Control panel" > "User Accounts" > "Credentials Manager" Icon of Credentials Manager

You want to do this:

git add -u
git reset HEAD path/to/file
git commit

Be sure and do this from the top level of the repo; add -u adds changes in the current directory (recursively).

The key line tells git to reset the version of the given path in the index (the staging area for the commit) to the version from HEAD (the currently checked-out commit).

And advance warning of a gotcha for others reading this: add -u stages all modifications, but doesn't add untracked files. This is the same as what commit -a does. If you want to add untracked files too, use add . to recursively add everything.

You can also circumvent scope inheritance and store things in the "global" scope.

If you have a main controller in your application which wraps all other controllers, you can install a "hook" to the global scope:

function RootCtrl($scope) {
    $scope.root = $scope;
}

Then in any child controller, you can access the "global" scope with $scope.root. Anything you set here will be globally visible.

Example:

function RootCtrl($scope) {_x000D_
  $scope.root = $scope;_x000D_
}_x000D_
_x000D_
function ChildCtrl($scope) {_x000D_
  $scope.setValue = function() {_x000D_
    $scope.root.someGlobalVar = 'someVal';_x000D_
  }_x000D_
}_x000D_
_x000D_
function OtherChildCtrl($scope) {_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
_x000D_
<div ng-app ng-controller="RootCtrl">_x000D_
  _x000D_
  <p ng-controller="ChildCtrl">_x000D_
    <button ng-click="setValue()">Set someGlobalVar</button>_x000D_
  </p>_x000D_
  _x000D_
  <p ng-controller="OtherChildCtrl">_x000D_
    someGlobalVar value: {{someGlobalVar}}_x000D_
  </p>_x000D_
_x000D_
</div>

show databases; worked for me.

It only worked for me in Firefox when accessing it from the window object.

Example...

window.onload = function()
{
 window.localStorage.clear();
}

You can overcome this error in two simple ways

First way

using namespace std;
include <string>
// then you can use string class the normal way

Second way

// after including the class string in your cpp file as follows
include <string>
/*Now when you are using a string class you have to put **std::** before you write 
string as follows*/
std::string name; // a string declaration

If you are using IIS Express and VS 2017:

I'm on OSX, I was using Android Studio instead of ADT and I had this issue, my problem was being behind a proxy with authentication, for what ever reason, In Android SDK Manager Window, under Preferences -> Others, I needed to uncheck the

"Force https://... sources to be fetched using http://..."

Also, there was no place to put the proxy credentials, but it will prompt you for them.

This one seems to be a better fit:

.NET is seeing an invalid SSL certificate on the other end of the connection. There is a workaround for it, but obviously not recommended for production code:

// Put this somewhere that is only once - like an initialization method
ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(ValidateCertificate);
...

static bool ValidateCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
{
   return true;
}

Expanding on jldupont's answer, you could create a wrapping element on the fly:

var target = document.getElementById('myElement');
var wrap = document.createElement('div');
wrap.appendChild(target.cloneNode(true));
alert(wrap.innerHTML);

I am cloning the element to avoid having to remove and reinsert the element in the actual document. This might be expensive if the element you wish to print has a very large tree below it, though.

In Java, you can escape quotes with \:

String value = " \"ROM\" ";

The cleanest approach I have found is a simplified version of the technique used by jQuery's offset. Similar to some of the other answers it starts with getBoundingClientRect; it then uses the window and the documentElement to adjust for scroll position as well as things like the margin on the body (often the default).

var rect = el.getBoundingClientRect();
var docEl = document.documentElement;

var rectTop = rect.top + window.pageYOffset - docEl.clientTop;
var rectLeft = rect.left + window.pageXOffset - docEl.clientLeft;

var els = document.getElementsByTagName("div");_x000D_
var docEl = document.documentElement;_x000D_
_x000D_
for (var i = 0; i < els.length; i++) {_x000D_
_x000D_
  var rect = els[i].getBoundingClientRect();_x000D_
_x000D_
  var rectTop = rect.top + window.pageYOffset - docEl.clientTop;_x000D_
  var rectLeft = rect.left + window.pageXOffset - docEl.clientLeft;_x000D_
_x000D_
  els[i].innerHTML = "<b>" + rectLeft + ", " + rectTop + "</b>";_x000D_
}

div {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  background-color: red;_x000D_
  border: 1px solid black;_x000D_

#abs {_x000D_
  position: absolute;_x000D_
  top: 250px;_x000D_
  left: 250px;_x000D_
}

I have uploaded a sample project. You can take a look.

VoiceRecorder

you can initialize it to ' ' instead. Also, the reason that you received an error -1 being too many characters is because it is treating '-' and 1 as separate.

This should do it, removing characters from the left by one or however many needed.

Set focus: The framework will handled moving focus in response to user input. To force focus to a specific view, call requestFocus()

try:

Cursor  cursor = db.rawQuery("select * from table",null);

AND for List<String>:

if (cursor.moveToFirst()) {
  while (!cursor.isAfterLast()) {
    String name = cursor.getString(cursor.getColumnIndex(countyname));

    list.add(name);
    cursor.moveToNext();
  }
}

The algorithm to go from infix to prefix expressions is:

-reverse input

TOS = top of stack
If next symbol is:
 - an operand -> output it
 - an operator ->
        while TOS is an operator of higher priority -> pop and output TOS
        push symbol
 - a closing parenthesis -> push it
 - an opening parenthesis -> pop and output TOS until TOS is matching
        parenthesis, then pop and discard TOS.

-reverse output

So your example goes something like (x PUSH, o POP):

2*3/(2-1)+5*(4-1)
)1-4(*5+)1-2(/3*2

Next

I don't know about expanding the information bar.

But you can get the timings set as a default for all queries showing in the "Messages" tab.

When in a Query window, go to the Query Menu item, select "query options" then select "advanced" in the "Execution" group and check the "set statistics time" / "set statistics IO" check boxes. These values will then show up in the messages area for each query without having to remember to put in the set stats on and off.

You could also use Shift + Alt + S to enable client statistics at any time

There are a couple of Expression Language implementations out there that does this for you, could be preferable to using your own implementation as or if your requirments grow, see for example JUEL and MVEL

I like and have successfully used MVEL in at least one project.

Also see the Stackflow post JSTL/JSP EL (Expression Language) in a non JSP (standalone) context

TL;DR

TEXT

• fixed max size of 65535 characters (you cannot limit the max size)
• takes 2 + c bytes of disk space, where c is the length of the stored string.
• cannot be (fully) part of an index. One would need to specify a prefix length.

VARCHAR(M)

• variable max size of M characters
• M needs to be between 1 and 65535
• takes 1 + c bytes (for M ≤ 255) or 2 + c (for 256 ≤ M ≤ 65535) bytes of disk space where c is the length of the stored string
• can be part of an index

More Details

TEXT has a fixed max size of 2¹6-1 = 65535 characters.
VARCHAR has a variable max size M up to M = 2¹6-1.
So you cannot choose the size of TEXT but you can for a VARCHAR.

The other difference is, that you cannot put an index (except for a fulltext index) on a TEXT column.
So if you want to have an index on the column, you have to use VARCHAR. But notice that the length of an index is also limited, so if your VARCHAR column is too long you have to use only the first few characters of the VARCHAR column in your index (See the documentation for CREATE INDEX).

But you also want to use VARCHAR, if you know that the maximum length of the possible input string is only M, e.g. a phone number or a name or something like this. Then you can use VARCHAR(30) instead of TINYTEXT or TEXT and if someone tries to save the text of all three "Lord of the Ring" books in your phone number column you only store the first 30 characters :)

Edit: If the text you want to store in the database is longer than 65535 characters, you have to choose MEDIUMTEXT or LONGTEXT, but be careful: MEDIUMTEXT stores strings up to 16 MB, LONGTEXT up to 4 GB. If you use LONGTEXT and get the data via PHP (at least if you use mysqli without store_result), you maybe get a memory allocation error, because PHP tries to allocate 4 GB of memory to be sure the whole string can be buffered. This maybe also happens in other languages than PHP.

However, you should always check the input (Is it too long? Does it contain strange code?) before storing it in the database.

Notice: For both types, the required disk space depends only on the length of the stored string and not on the maximum length.
E.g. if you use the charset latin1 and store the text "Test" in VARCHAR(30), VARCHAR(100) and TINYTEXT, it always requires 5 bytes (1 byte to store the length of the string and 1 byte for each character). If you store the same text in a VARCHAR(2000) or a TEXT column, it would also require the same space, but, in this case, it would be 6 bytes (2 bytes to store the string length and 1 byte for each character).

For more information have a look at the documentation.

Finally, I want to add a notice, that both, TEXT and VARCHAR are variable length data types, and so they most likely minimize the space you need to store the data. But this comes with a trade-off for performance. If you need better performance, you have to use a fixed length type like CHAR. You can read more about this here.

Here's an easy and short way to get a substring if you know the index:

let s = "www.stackoverflow.com"
let result = String(s.characters.prefix(17)) // "www.stackoverflow"

It won't crash the app if your index exceeds string's length:

let s = "short"
let result = String(s.characters.prefix(17)) // "short"

Both examples are Swift 3 ready.

To Fix The "Missing "server" JVM at C:\Program Files\Java\jre7\bin\server\jvm­­.dll, please install or use the JRE or JDK that contains these missing components.

Follow these steps:

Go to oracle.com and install Java JRE7 (Check if Java 6 is not installed already)

After that, go to C:/Program files/java/jre7/bin

Here, create an folder called Server

Now go into the C:/Program files/java/jre7/bin/client folder

Copy all the data in this folder into the new C:/Program files/java/jre7/bin/Server folder

The answers provided did not work for me (Chrome or Firefox) while creating PWA for local development and testing. DO NOT USE FOR PRODUCTION! I was able to use the following:

1. Online certificate tools site with the following options:
   • Common Names: Add both the "localhost" and IP of your system e.g. 192.168.1.12
   • Subject Alternative Names: Add "DNS" = "localhost" and "IP" = <your ip here, e.g. 192.168.1.12>
   • "CRS" drop down options set to "Self Sign"
   • all other options were defaults
2. Download all links
3. Import .p7b cert into Windows by double clicking and select "install"/ OSX?/Linux?
4. Added certs to node app... using Google's PWA example
   • add const https = require('https'); const fs = require('fs'); to the top of the server.js file
   • comment out return app.listen(PORT, () => { ... }); at the bottom of server.js file
   • add below https.createServer({ key: fs.readFileSync('./cert.key','utf8'), cert: fs.readFileSync('./cert.crt','utf8'), requestCert: false, rejectUnauthorized: false }, app).listen(PORT)

I have no more errors in Chrome or Firefox

The linefeed character \n is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n instead, then it'll both see the line-break with only \n and \r\n, I've never had any problems using it.

Also, you should look into using a StringBuilder instead of concatenating the String in the while-loop at BookCatalog.toString(), it is a lot more effective. For instance:

public String toString() {
        BookNode current = front;
        StringBuilder sb = new StringBuilder();
        while (current!=null){
            sb.append(current.getData().toString()+"\r\n ");
            current = current.getNext();
        }
        return sb.toString();
}

For survivorship bias free data, the only reliable source I have found is QuantQuote (http://quantquote.com)

Data comes in minute, second, or tick resolution, link to their historical stock data.

There was a suggestion for kibot above. I would do a quick google search before buying from them, you'll find lots posts like this with warnings about kibot data quality problems. It is also telling that their supposedly survivorship bias free sp500 only has 570 symbols for 14 years. That's pretty much impossible, sp500 changes by 1-2 symbols per month....

If your file contains n lines, then your script has to read the file n times; so if you double the length of the file, you quadruple the amount of work your script does — and almost all of that work is simply thrown away, since all you want to do is loop over the lines in order.

Instead, the best way to loop over the lines of a file is to use a while loop, with the condition-command being the read builtin:

while IFS= read -r line ; do
    # $line is a single line of the file, as a single string
    : ... commands that use $line ...
done < input_file.txt

In your case, since you want to split the line into an array, and the read builtin actually has special support for populating an array variable, which is what you want, you can write:

while read -r -a line ; do
    echo ""${line[1]}" "${line[3]}"" >> out.txt
done < /path/of/my/text

or better yet:

while read -r -a line ; do
    echo "${line[1]} ${line[3]}"
done < /path/of/my/text > out.txt

However, for what you're doing you can just use the cut utility:

cut -d' ' -f2,4 < /path/of/my/text > out.txt

(or awk, as Tom van der Woerdt suggests, or perl, or even sed).

You can install a tarball without extracting it first. Just navigate to the directory containing your .tar.gz file from your command prompt and enter this command:

pip install my-tarball-file-name.tar.gz

I am running python 3.4.3 and this works for me. I can't tell if this would work on other versions of python though.

The Operating System is a generic name given to all of the elements (user interface, libraries, resources) which make up the system as a whole.

The kernel is "brain" of the operating system, which controls everything from access to the hard disk to memory management. Whenever you want to do anything, it goes though the kernel.

For MySQL Workbench 8.0 navigate to:

Server > Data Import

A new tab called Administration - Data Import/Restore appears. There you can choose to import a Dump Project Folder or use a specific SQL file according to your needs. Then you must select a schema where the data will be imported to, or you have to click the New... button to type a name for the new schema.

Then you can select the database objects to be imported or just click the Start Import button in the lower right part of the tab area.

Having done that and if the import was successful, you'll need to update the Schema Navigator by clicking the arrow circle icon.

That's it!

For more detailed info, check the MySQL Workbench Manual: 6.5.2 SQL Data Export and Import Wizard

@Query("SELECT rd FROM ReleaseDateType rd, CacheMedia cm WHERE ...")

UConverter can be used since PHP 5.5. UConverter is better the choice if you use intl extension and don't use mbstring.

function replace_invalid_byte_sequence($str)
{
    return UConverter::transcode($str, 'UTF-8', 'UTF-8');
}

function replace_invalid_byte_sequence2($str)
{
    return (new UConverter('UTF-8', 'UTF-8'))->convert($str);
}

htmlspecialchars can be used to remove invalid byte sequence since PHP 5.4. Htmlspecialchars is better than preg_match for handling large size of byte and the accuracy. A lot of the wrong implementation by using regular expression can be seen.

function replace_invalid_byte_sequence3($str)
{
    return htmlspecialchars_decode(htmlspecialchars($str, ENT_SUBSTITUTE, 'UTF-8'));
}

An output stream is generally related to some data destination like a file or a network etc.In java output stream is a destination where data is eventually written and it ends

import java.io.printstream;

class PPrint {
    static PPrintStream oout = new PPrintStream();
}

class PPrintStream {
    void print(String str) { 
        System.out.println(str)
    }
}

class outputstreamDemo {
    public static void main(String args[]) {
        System.out.println("hello world");
        System.out.prinln("this is output stream demo");
    }
}

If you get code behind, use some like this

        MyCustomObject myObject = new MyCustomObject();
        myObject.name='try';
        //OBJECT -> JSON
        var javaScriptSerializer = new System.Web.Script.Serialization.JavaScriptSerializer();
        string myObjectJson = javaScriptSerializer.Serialize(myObject);
        //return JSON   
        Response.Clear();     
        Response.ContentType = "application/json; charset=utf-8";
        Response.Write(myObjectJson );
        Response.End();

So you return a json object serialized with all attributes of MyCustomObject.

This solution will also work for the following URLs, without breaking anchor links to different pages.

http://www.example.com/dir/index.html
http://www.example.com/dir/index.html#anchor

./index.html
./index.html#anchor

etc.

var $root = $('html, body');
$('a').on('click', function(event){
    var hash = this.hash;
    // Is the anchor on the same page?
    if (hash && this.href.slice(0, -hash.length-1) == location.href.slice(0, -location.hash.length-1)) {
        $root.animate({
            scrollTop: $(hash).offset().top
        }, 'normal', function() {
            location.hash = hash;
        });
        return false;
    }
});

I haven't tested this in all browsers, yet.

When running git filter-branch using a newer version of git (2.22+ maybe?), it says to use this new tool git-filter-repo. This tool certainly simplified things for me.

Filtering with filter-repo

Commands to create the XYZ repo from the original question:

# create local clone of original repo in directory XYZ
tmp $ git clone [email protected]:user/original.git XYZ

# switch to working in XYZ
tmp $ cd XYZ

# keep subdirectories XY1 and XY2 (dropping ABC)
XYZ $ git filter-repo --path XY1 --path XY2

# note: original remote origin was dropped
# (protecting against accidental pushes overwriting original repo data)

# XYZ $ ls -1
# XY1
# XY2

# XYZ $ git log --oneline
# last commit modifying ./XY1 or ./XY2
# first commit modifying ./XY1 or ./XY2

# point at new hosted, dedicated repo
XYZ $ git remote add origin [email protected]:user/XYZ.git

# push (and track) remote master
XYZ $ git push -u origin master

assumptions: * remote XYZ repo was new and empty before the push

Filtering and moving

In my case, I also wanted to move a couple of directories for a more consistent structure. Initially, I ran that simple filter-repo command followed by git mv dir-to-rename, but I found I could get a slightly "better" history using the --path-rename option. Instead of seeing last modified 5 hours ago on moved files in the new repo I now see last year (in the GitHub UI), which matches the modified times in the original repo.

Instead of...

git filter-repo --path XY1 --path XY2 --path inconsistent
git mv inconsistent XY3  # which updates last modification time

I ultimately ran...

git filter-repo --path XY1 --path XY2 --path inconsistent --path-rename inconsistent:XY3

• I thought the Git Rev News blog post explained well the reasoning behind creating yet another repo-filtering tool.
• I initially tried the path of creating a sub-directory matching the target repo name in the original repository and then filtering (using git filter-repo --subdirectory-filter dir-matching-new-repo-name). That command correctly converted that subdirectory to the root of the copied local repo, but it also resulted in a history of only the three commits it took to create the subdirectory. (I hadn't realized that --path could be specified multiple times; thereby, obviating the need to create a subdirectory in the source repo.) Since someone had committed to the source repo by the time I noticed that I'd failed to carry forward the history, I just used git reset commit-before-subdir-move --hard after the clone command, and added --force to the filter-repo command to get it to operate on the slightly modified local clone.

git clone ...
git reset HEAD~7 --hard      # roll back before mistake
git filter-repo ... --force  # tell filter-repo the alterations are expected

• I was stumped on the install since I was unaware of the extension pattern with git, but ultimately I cloned git-filter-repo and symlinked it to $(git --exec-path):

ln -s ~/github/newren/git-filter-repo/git-filter-repo $(git --exec-path)

If it's a CLOB why can't we to_char the column and then search normally ?

Create a table

CREATE TABLE MY_TABLE(Id integer PRIMARY KEY, Name varchar2(20), message clob);

Create few records in this table

INSERT INTO MY_TABLE VALUES(1,'Tom','Hi This is Row one');
INSERT INTO MY_TABLE VALUES(2,'Lucy', 'Hi This is Row two');
INSERT INTO MY_TABLE VALUES(3,'Frank', 'Hi This is Row three');
INSERT INTO MY_TABLE VALUES(4,'Jane', 'Hi This is Row four');
INSERT INTO MY_TABLE VALUES(5,'Robert', 'Hi This is Row five');
COMMIT;

Search in the clob column

SELECT * FROM MY_TABLE where to_char(message) like '%e%';

Results

ID   NAME    MESSAGE   
===============================  
1    Tom     Hi This is Row one         
3    Frank   Hi This is Row three
5    Robert  Hi This is Row five

you can simply cast a string array to int array by:

var converted = arr.Select(int.Parse)

if you want to get the value attribute (buttonValue) then I'd use:

<script type="text/javascript">
    $(document).ready(function() {
        $('.my_button').click(function() {
            alert($(this).attr('value'));
        });
    });
</script>

iPad Media Queries (All generations - including iPad mini)

Thanks to Apple's work in creating a consistent experience for users, and easy time for developers, all 5 different iPads (iPads 1-5 and iPad mini) can be targeted with just one CSS media query. The next few lines of code should work perfect for a responsive design.

iPad in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px)  { /* STYLES GO HERE */}

iPad in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape) { /* STYLES GO HERE */}

iPad in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait) { /* STYLES GO HERE */ }

iPad 3 & 4 Media Queries

If you're looking to target only 3rd and 4th generation Retina iPads (or tablets with similar resolution) to add @2x graphics, or other features for the tablet's Retina display, use the following media queries.

Retina iPad in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */}

Retina iPad in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */}

Retina iPad in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */ }

iPad 1 & 2 Media Queries

If you're looking to supply different graphics or choose different typography for the lower resolution iPad display, the media queries below will work like a charm in your responsive design!

iPad 1 & 2 in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (-webkit-min-device-pixel-ratio: 1){ /* STYLES GO HERE */}

iPad 1 & 2 in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape)
and (-webkit-min-device-pixel-ratio: 1)  { /* STYLES GO HERE */}

iPad 1 & 2 in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait) 
and (-webkit-min-device-pixel-ratio: 1) { /* STYLES GO HERE */ }

All older answers' methods are deprecated by Google (supposedly because of troubles like this), since API 21 you need to use the Camera 2 API:

This class was deprecated in API level 21. We recommend using the new android.hardware.camera2 API for new applications.

In the newer API you have almost complete power over the Android device camera and documentation explicitly advice to

String[] getCameraIdList()

and then use obtained CameraId to open the camera:

void openCamera(String cameraId, CameraDevice.StateCallback callback, Handler handler)

99% of the frontal cameras have id = "1", and the back camera id = "0" according to this:

Non-removable cameras use integers starting at 0 for their identifiers, while removable cameras have a unique identifier for each individual device, even if they are the same model.

However, this means if device situation is rare like just 1-frontal -camera tablet you need to count how many embedded cameras you have, and place the order of the camera by its importance ("0"). So CAMERA_FACING_FRONT == 1 CAMERA_FACING_BACK == 0, which implies that the back camera is more important than frontal.

I don't know about a uniform method to identify the frontal camera on all Android devices. Simply said, the Android OS inside the device can't really find out which camera is exactly where for some reasons: maybe the only camera hardcoded id is an integer representing its importance or maybe on some devices whichever side you turn will be .. "back".

Documentation: https://developer.android.com/reference/android/hardware/camera2/package-summary.html

Explicit Examples: https://github.com/googlesamples/android-Camera2Basic

For the older API (it is not recommended, because it will not work on modern phones newer Android version and transfer is a pain-in-the-arse). Just use the same Integer CameraID (1) to open frontal camera like in this answer:

cam = Camera.open(1);

If you trust OpenCV to do the camera part:

Inside

    <org.opencv.android.JavaCameraView
    ../>

use the following for the frontal camera:

        opencv:camera_id="1"

If you want to know the timezone of the client relative to GMT/UTC here you go:

var d = new Date();
var tz = d.toString().split("GMT")[1].split(" (")[0]; // timezone, i.e. -0700

If you'd like the actual name of the timezone you can try this:

var d = new Date();
var tz = d.toString().split("GMT")[1]; // timezone, i.e. -0700 (Pacific Daylight Time)

UPDATE 1

Per the first comment by you can also use d.getTimezoneOffset() to get the offset in minutes from UTC. Couple of gotchas with it though.

1. The sign (+/-) of the minutes returned is probably the opposite of what you'd expect. If you are 8 hours behind UTC it will return 480 not -480. See MDN or MSDN for more documentation.
2. It doesn't actually return what timezone the client is reporting it is in like the second example I gave. Just the minutes offset from UTC currently. So it will change based on daylight savings time.

UPDATE 2

While the string splitting examples work they can be confusing to read. Here is a regex version that should be easier to understand and is probably faster (both methods are very fast though).

If you want to know the timezone of the client relative to GMT/UTC here you go:

var gmtRe = /GMT([\-\+]?\d{4})/; // Look for GMT, + or - (optionally), and 4 characters of digits (\d)
var d = new Date().toString();
var tz = gmtRe.exec(d)[1]; // timezone, i.e. -0700

If you'd like the actual name of the timezone try this:

var tzRe = /\(([\w\s]+)\)/; // Look for "(", any words (\w) or spaces (\s), and ")"
var d = new Date().toString();
var tz = tzRe.exec(d)[1]; // timezone, i.e. "Pacific Daylight Time"

The other answers answer your question. Another important thing to know about names in Python is that they are either local or global on a per-scope basis.

Consider this, for example:

value = 42

def doit():
    print value
    value = 0

doit()
print value

You can probably guess that the value = 0 statement will be assigning to a local variable and not affect the value of the same variable declared outside the doit() function. You may be more surprised to discover that the code above won't run. The statement print value inside the function produces an UnboundLocalError.

The reason is that Python has noticed that, elsewhere in the function, you assign the name value, and also value is nowhere declared global. That makes it a local variable. But when you try to print it, the local name hasn't been defined yet. Python in this case does not fall back to looking for the name as a global variable, as some other languages do. Essentially, you cannot access a global variable if you have defined a local variable of the same name anywhere in the function.

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

import numpy as np
from scipy.signal import butter, lfilter, freqz
import matplotlib.pyplot as plt


def butter_lowpass(cutoff, fs, order=5):
    nyq = 0.5 * fs
    normal_cutoff = cutoff / nyq
    b, a = butter(order, normal_cutoff, btype='low', analog=False)
    return b, a

def butter_lowpass_filter(data, cutoff, fs, order=5):
    b, a = butter_lowpass(cutoff, fs, order=order)
    y = lfilter(b, a, data)
    return y


# Filter requirements.
order = 6
fs = 30.0       # sample rate, Hz
cutoff = 3.667  # desired cutoff frequency of the filter, Hz

# Get the filter coefficients so we can check its frequency response.
b, a = butter_lowpass(cutoff, fs, order)

# Plot the frequency response.
w, h = freqz(b, a, worN=8000)
plt.subplot(2, 1, 1)
plt.plot(0.5*fs*w/np.pi, np.abs(h), 'b')
plt.plot(cutoff, 0.5*np.sqrt(2), 'ko')
plt.axvline(cutoff, color='k')
plt.xlim(0, 0.5*fs)
plt.title("Lowpass Filter Frequency Response")
plt.xlabel('Frequency [Hz]')
plt.grid()


# Demonstrate the use of the filter.
# First make some data to be filtered.
T = 5.0         # seconds
n = int(T * fs) # total number of samples
t = np.linspace(0, T, n, endpoint=False)
# "Noisy" data.  We want to recover the 1.2 Hz signal from this.
data = np.sin(1.2*2*np.pi*t) + 1.5*np.cos(9*2*np.pi*t) + 0.5*np.sin(12.0*2*np.pi*t)

# Filter the data, and plot both the original and filtered signals.
y = butter_lowpass_filter(data, cutoff, fs, order)

plt.subplot(2, 1, 2)
plt.plot(t, data, 'b-', label='data')
plt.plot(t, y, 'g-', linewidth=2, label='filtered data')
plt.xlabel('Time [sec]')
plt.grid()
plt.legend()

plt.subplots_adjust(hspace=0.35)

This will check for empty textarea as well as will not allow only Spaces in textarea coz that looks empty too.

 var txt_msg = $("textarea").val();

 if (txt_msg.replace(/^\s+|\s+$/g, "").length == 0 || txt_msg=="") {
    return false;
  }

Here's my solution:

var content = "Visit https://wwww.google.com or watch this video: https://www.youtube.com/watch?v=0T4DQYgsazo and news at http://www.bbc.com";
content = replaceUrlsWithLinks(content, "http://");
content = replaceUrlsWithLinks(content, "https://");

function replaceUrlsWithLinks(content, protocol) {
    var startPos = 0;
    var s = 0;

    while (s < content.length) {
        startPos = content.indexOf(protocol, s);

        if (startPos < 0)
            return content;

        let endPos = content.indexOf(" ", startPos + 1);

        if (endPos < 0)
            endPos = content.length;

        let url = content.substr(startPos, endPos - startPos);

        if (url.endsWith(".") || url.endsWith("?") || url.endsWith(",")) {
            url = url.substr(0, url.length - 1);
            endPos--;
        }

        if (ROOTNS.utils.stringsHelper.validUrl(url)) {
            let link = "<a href='" + url + "'>" + url + "</a>";
            content = content.substr(0, startPos) + link + content.substr(endPos);
            s = startPos + link.length;
        } else {
            s = endPos + 1;
        }
    }

    return content;
}

function validUrl(url) {
    try {
        new URL(url);
        return true;
    } catch (e) {
        return false;
    }
}

To elaborate on the answer @xhh provided, you can append the red, green, and blue to format your string as "rgb(0,0,0)" before returning it.

/**
* 
* @param colorStr e.g. "#FFFFFF"
* @return String - formatted "rgb(0,0,0)"
*/
public static String hex2Rgb(String colorStr) {
    Color c = new Color(
        Integer.valueOf(hexString.substring(1, 3), 16), 
        Integer.valueOf(hexString.substring(3, 5), 16), 
        Integer.valueOf(hexString.substring(5, 7), 16));

    StringBuffer sb = new StringBuffer();
    sb.append("rgb(");
    sb.append(c.getRed());
    sb.append(",");
    sb.append(c.getGreen());
    sb.append(",");
    sb.append(c.getBlue());
    sb.append(")");
    return sb.toString();
}

UPDATE Table SET Column = REPLACE(Column, char(9), '')

Using f-strings, in Python 3.6+.

from datetime import datetime

date_string = f'{datetime.now():%Y-%m-%d %H:%M:%S%z}'

This one works for me.

import { Component,Input,OnInit} from '@angular/core';
import {DomSanitizer,SafeResourceUrl,} from '@angular/platform-browser';

@Component({
    moduleId: module.id,
    selector: 'player',
    templateUrl: './player.component.html',
    styleUrls:['./player.component.scss'],
    
})
export class PlayerComponent implements OnInit{
    @Input()
    id:string; 
    url: SafeResourceUrl;
    constructor (public sanitizer:DomSanitizer) {
    }
    ngOnInit() {
        this.url = this.sanitizer.bypassSecurityTrustResourceUrl(this.id);      
    }
}

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

Another way of returning all files in subdirectories is to use the pathlib module, introduced in Python 3.4, which provides an object oriented approach to handling filesystem paths (Pathlib is also available on Python 2.7 via the pathlib2 module on PyPi):

from pathlib import Path

rootdir = Path('C:/Users/sid/Desktop/test')
# Return a list of regular files only, not directories
file_list = [f for f in rootdir.glob('**/*') if f.is_file()]

# For absolute paths instead of relative the current dir
file_list = [f for f in rootdir.resolve().glob('**/*') if f.is_file()]

Since Python 3.5, the glob module also supports recursive file finding:

import os
from glob import iglob

rootdir_glob = 'C:/Users/sid/Desktop/test/**/*' # Note the added asterisks
# This will return absolute paths
file_list = [f for f in iglob(rootdir_glob, recursive=True) if os.path.isfile(f)]

The file_list from either of the above approaches can be iterated over without the need for a nested loop:

for f in file_list:
    print(f) # Replace with desired operations

When you call figure, simply number the plot.

x = arange(5)
y = np.exp(5)
plt.figure(0)
plt.plot(x, y)

z = np.sin(x)
plt.figure(1)
plt.plot(x, z)

w = np.cos(x)
plt.figure(0) # Here's the part I need
plt.plot(x, w)

Edit: Note that you can number the plots however you want (here, starting from 0) but if you don't provide figure with a number at all when you create a new one, the automatic numbering will start at 1 ("Matlab Style" according to the docs).

It's because val is not null, but contains 'null' as a string.

Try to check with 'null'

if ('null' != val)

For an explanation of when and why this works, see the details below.

// Regex for special symbols

var regex_symbols= /[-!$%^&*()_+|~=`{}\[\]:\/;<>?,.@#]/;

You can simply do

print 2*'hello'

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

As well as the XML settings identified by droidgren, my tests have shown that if the text you want to display is shorter than the width of the textview, then the marquee won't scroll at all. Possible solutions are to set the width of the view to a size smaller than the length of the text, or to concatenate the string to itself 2 or 3 times, with perhaps appropriate whitespace in-between so that the scrolling looks ok.

For anyone who, like me, reads this because they need to update a giant legacy project to 5.6: as the answers here point out, there is no quick fix: you really do need to find each occurrence of the problem manually, and fix it.

The most convenient way I found to find all problematic lines in a project (short of using a full-blown static code analyzer, which is very accurate but I don't know any that take you to the correct position in the editor right away) was using Visual Studio Code, which has a nice PHP linter built in, and its search feature which allows searching by Regex. (Of course, you can use any IDE/Code editor for this that does PHP linting and Regex searches.)

Using this regex:

^(?!.*function).*(\&\$)

it is possible to search project-wide for the occurrence of &$ only in lines that are not a function definition.

This still turns up a lot of false positives, but it does make the job easier.

VSCode's search results browser makes walking through and finding the offending lines super easy: you just click through each result, and look out for those that the linter underlines red. Those you need to fix.

It will be something like:

R.drawable.resourcename

Make sure you don't have the Android.R namespace imported as it can confuse Eclipse (if that's what you're using).

If that doesn't work, you can always use a context's getResources method ...

Drawable resImg = this.context.getResources().getDrawable(R.drawable.resource);

Where this.context is intialised as an Activity, Service or any other Context subclass.

Update:

If it's the name you want, the Resources class (returned by getResources()) has a getResourceName(int) method, and a getResourceTypeName(int)?

Update 2:

The Resources class has this method:

public int getIdentifier (String name, String defType, String defPackage) 

Which returns the integer of the specified resource name, type & package.

UPDATE MyTable SET MyDate = CONVERT(datetime, '2009/07/16 08:28:01', 120)

You need install pysocks , my version is 1.0 and the code works for me:

import socket
import socks
import requests
ip='localhost' # change your proxy's ip
port = 0000 # change your proxy's port
socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, ip, port)
socket.socket = socks.socksocket
url = u'http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=inurl%E8%A2%8B'
print(requests.get(url).text)

For anyone trying to do this in asp.net core. You can use claims.

public class CustomEmailProvider : IUserIdProvider
{
    public virtual string GetUserId(HubConnectionContext connection)
    {
        return connection.User?.FindFirst(ClaimTypes.Email)?.Value;
    }
}

Any identifier can be used, but it must be unique. If you use a name identifier for example, it means if there are multiple users with the same name as the recipient, the message would be delivered to them as well. I have chosen email because it is unique to every user.

Then register the service in the startup class.

services.AddSingleton<IUserIdProvider, CustomEmailProvider>();

Next. Add the claims during user registration.

var result = await _userManager.CreateAsync(user, Model.Password);
if (result.Succeeded)
{
    await _userManager.AddClaimAsync(user, new Claim(ClaimTypes.Email, Model.Email));
}

To send message to the specific user.

public class ChatHub : Hub
{
    public async Task SendMessage(string receiver, string message)
    {
        await Clients.User(receiver).SendAsync("ReceiveMessage", message);
    }
}

Note: The message sender won't be notified the message is sent. If you want a notification on the sender's end. Change the SendMessage method to this.

public async Task SendMessage(string sender, string receiver, string message)
{
    await Clients.Users(sender, receiver).SendAsync("ReceiveMessage", message);
}

These steps are only necessary if you need to change the default identifier. Otherwise, skip to the last step where you can simply send messages by passing userIds or connectionIds to SendMessage. For more

Calling a polymorphic function from a constructor is a recipe for disaster in most OO languages. Different languages will perform differently when this situation is encountered.

The basic problem is that in all languages the Base type(s) must be constructed previous to the Derived type. Now, the problem is what does it mean to call a polymorphic method from the constructor. What do you expect it to behave like? There are two approaches: call the method at the Base level (C++ style) or call the polymorphic method on an unconstructed object at the bottom of the hierarchy (Java way).

In C++ the Base class will build its version of the virtual method table prior to entering its own construction. At this point a call to the virtual method will end up calling the Base version of the method or producing a pure virtual method called in case it has no implementation at that level of the hierarchy. After the Base has been fully constructed, the compiler will start building the Derived class, and it will override the method pointers to point to the implementations in the next level of the hierarchy.

class Base {
public:
   Base() { f(); }
   virtual void f() { std::cout << "Base" << std::endl; } 
};
class Derived : public Base
{
public:
   Derived() : Base() {}
   virtual void f() { std::cout << "Derived" << std::endl; }
};
int main() {
   Derived d;
}
// outputs: "Base" as the vtable still points to Base::f() when Base::Base() is run

In Java, the compiler will build the virtual table equivalent at the very first step of construction, prior to entering the Base constructor or Derived constructor. The implications are different (and to my likings more dangerous). If the base class constructor calls a method that is overriden in the derived class the call will actually be handled at the derived level calling a method on an unconstructed object, yielding unexpected results. All attributes of the derived class that are initialized inside the constructor block are yet uninitialized, including 'final' attributes. Elements that have a default value defined at the class level will have that value.

public class Base {
   public Base() { polymorphic(); }
   public void polymorphic() { 
      System.out.println( "Base" );
   }
}
public class Derived extends Base
{
   final int x;
   public Derived( int value ) {
      x = value;
      polymorphic();
   }
   public void polymorphic() {
      System.out.println( "Derived: " + x ); 
   }
   public static void main( String args[] ) {
      Derived d = new Derived( 5 );
   }
}
// outputs: Derived 0
//          Derived 5
// ... so much for final attributes never changing :P

As you see, calling a polymorphic (virtual in C++ terminology) methods is a common source of errors. In C++, at least you have the guarantee that it will never call a method on a yet unconstructed object...

I could advise you to use Exp4j. It is easy to understand as you can see from the following example code:

Expression e = new ExpressionBuilder("3 * sin(y) - 2 / (x - 2)")
    .variables("x", "y")
    .build()
    .setVariable("x", 2.3)
    .setVariable("y", 3.14);
double result = e.evaluate();

Modules go in site-packages and executables go in your system's executable path. For your environment, this path is /usr/local/bin/.

To avoid having to deal with this, simply use easy_install, distribute or pip. These tools know which files need to go where.

Construct some data

df <- data.frame( name=c("John", "Adam"), date=c(3, 5) )

Extract exact matches:

subset(df, date==3)

  name date
1 John    3

Extract matches in range:

subset(df, date>4 & date<6)

  name date
2 Adam    5

The following syntax produces identical results:

df[df$date>4 & df$date<6, ]

  name date
2 Adam    5

Most answers get you the current path and are context sensitive. In order to run your script from any directory, use the below snippet.

DIR="$( cd "$( dirname "$0" )" && pwd )"

By switching directories in a subshell, we can then call pwd and get the correct path of the script regardless of context.

You can then use $DIR as "$DIR/path/to/file"

Update alpha 47

As of alpha 47 the below answer (for alpha46 and below) is not longer required. Now the Http module handles automatically the errores returned. So now is as easy as follows

    (data) => this.data = data,
    (err) => this.error = err); // Reach here if fails

Alpha 46 and below

You can handle the response in the map(...), before the subscribe.

http
  .get('Some Url')
  .map(res => {
    // If request fails, throw an Error that will be caught
    if(res.status < 200 || res.status >= 300) {
      throw new Error('This request has failed ' + res.status);
    } 
    // If everything went fine, return the response
    else {
      return res.json();
    }
  })
  .subscribe(
    (data) => this.data = data, // Reach here if res.status >= 200 && <= 299
    (err) => this.error = err); // Reach here if fails

Here's a plnkr with a simple example.

Note that in the next release this won't be necessary because all status codes below 200 and above 299 will throw an error automatically, so you won't have to check them by yourself. Check this commit for more info.

There is a new API that makes this even simpler.

plt.gca().invert_xaxis()

and/or

plt.gca().invert_yaxis()

Theoretically, yes. Practice, not. Most kernels (incl. linux) doesn't allow you a second bind() to an already allocated port. It weren't a really big patch to make this allowed.

Conceptionally, we should differentiate between socket and port. Sockets are bidirectional communication endpoints, i.e. "things" where we can send and receive bytes. It is a conceptional thing, there is no such field in a packet header named "socket".

Port is an identifier which is capable to identify a socket. In case of the TCP, a port is a 16 bit integer, but there are other protocols as well (for example, on unix sockets, a "port" is essentially a string).

The main problem is the following: if an incoming packet arrives, the kernel can identify its socket by its destination port number. It is a most common way, but it is not the only possibility:

• Sockets can be identified by the destination IP of the incoming packets. This is the case, for example, if we have a server using two IPs simultanously. Then we can run, for example, different webservers on the same ports, but on the different IPs.
• Sockets can be identified by their source port and ip as well. This is the case in many load balancing configurations.

Because you are working on an application server, it will be able to do that.

This is a bit of an old post, but there is actually a way to do an onclick operator that calls a function instead of going anywhere in ASP.NET

helper.ActionLink("Choose", null, null, null, 
    new {@onclick = "Locations.Choose(" + location.Id + ")", @href="#"})

If you specify empty quotes or the like in the controller/action, it'll likely add a link to what you listed. You can do that, and do a return false in the onclick. You can read more about that at:

What's the effect of adding 'return false' to a click event listener?

If you're doing this onclick in an cshtml file, it'd be a bit cleaner to just specify the link yourself (a href...) instead of having the ActionLink handle it. If you're doing an HtmlHelper, like my example above is coming from, then I'd argue that calling ActionLink is an okay solution, or potentially better, is to use tagbuilder instead.

Seq is a trait that List implements.

If you define your container as Seq, you can use any container that implements Seq trait.

scala> def sumUp(s: Seq[Int]): Int = { s.sum }
sumUp: (s: Seq[Int])Int

scala> sumUp(List(1,2,3))
res41: Int = 6

scala> sumUp(Vector(1,2,3))
res42: Int = 6

scala> sumUp(Seq(1,2,3))
res44: Int = 6

Note that

scala> val a = Seq(1,2,3)
a: Seq[Int] = List(1, 2, 3)

Is just a short hand for:

scala> val a: Seq[Int] = List(1,2,3)
a: Seq[Int] = List(1, 2, 3)

if the container type is not specified, the underlying data structure defaults to List.

I am using Pillow 4.1.1 (the successor of PIL) in Python 3.5. The conversion between Pillow and numpy is straightforward.

from PIL import Image
import numpy as np
im = Image.open('1.jpg')
im2arr = np.array(im) # im2arr.shape: height x width x channel
arr2im = Image.fromarray(im2arr)

One thing that needs noticing is that Pillow-style im is column-major while numpy-style im2arr is row-major. However, the function Image.fromarray already takes this into consideration. That is, arr2im.size == im.size and arr2im.mode == im.mode in the above example.

We should take care of the HxWxC data format when processing the transformed numpy arrays, e.g. do the transform im2arr = np.rollaxis(im2arr, 2, 0) or im2arr = np.transpose(im2arr, (2, 0, 1)) into CxHxW format.

For me, it's very simple:

     private boolean mLoading = false;

     mList.setOnScrollListener(new RecyclerView.OnScrollListener() {

        @Override
        public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
            super.onScrolled(recyclerView, dx, dy);

            int totalItem = mLinearLayoutManager.getItemCount();
            int lastVisibleItem = mLinearLayoutManager.findLastVisibleItemPosition();

            if (!mLoading && lastVisibleItem == totalItem - 1) {
                mLoading = true;
                // Scrolled to bottom. Do something here.
                mLoading = false;
            }
        }
    });

Be careful with asynchronous jobs: mLoading must be changed at the end of the asynchronous jobs. Hope it will be helpful!

You need to use the ref prop for the TextInput component.
Then you need a create a function that gets called on onSubmitEditing prop that moves the focus on the second TextInput ref.

var InputScreen = React.createClass({
    _focusNextField(nextField) {
        this.refs[nextField].focus()
    },

    render: function() {
        return (
            <View style={styles.container}>
                <TextInput
                    ref='1'
                    style={styles.input}
                    placeholder='Normal'
                    returnKeyType='next'
                    blurOnSubmit={false}
                    onSubmitEditing={() => this._focusNextField('2')}
                />
                <TextInput
                    ref='2'
                    style={styles.input}
                    keyboardType='email-address'
                    placeholder='Email Address'
                    returnKeyType='next'
                    blurOnSubmit={false}
                    onSubmitEditing={() => this._focusNextField('3')}
                />
                <TextInput
                    ref='3'
                    style={styles.input}
                    keyboardType='url'
                    placeholder='URL'
                    returnKeyType='next'
                    blurOnSubmit={false}
                    onSubmitEditing={() => this._focusNextField('4')}
                />
                <TextInput
                    ref='4'
                    style={styles.input}
                    keyboardType='numeric'
                    placeholder='Numeric'
                    blurOnSubmit={false}
                    onSubmitEditing={() => this._focusNextField('5')}
                />
                <TextInput
                    ref='5'
                    style={styles.input}
                    keyboardType='numbers-and-punctuation'
                    placeholder='Numbers & Punctuation'
                    returnKeyType='done'
                />
            </View>
        );
    }
});

LIKE is used for pattern matching and = is used for equality test (as defined by the COLLATION in use).

= can use indexes while LIKE queries usually require testing every single record in the result set to filter it out (unless you are using full text search) so = has better performance.

An assertion Error is thrown when say "You have written a code that should not execute at all costs because according to you logic it should not happen. BUT if it happens then throw AssertionError. And you don't catch it." In such a case you throw an Assertion error.

new IllegalStateException("Must not instantiate an element of this class")' // Is an Exception not error.

Note: Assertion Error comes under java.lang.Error And Errors not meant to be caught.

I had the same problem. My customer ordered me Python 3.4 script that updates XLS (not XLSX) Excel files.

The 1st package xlrd was installed by "pip install" without problems in my Python home.

The 2nd one xlwt needed to say "pip install xlwt-future" to be compatible.

The 3rd one xlutils has no support for Python 3, but I adapted it a little bit and now it works at least for dummy script:

#!C:\Python343\python
from xlutils.copy import copy # http://pypi.python.org/pypi/xlutils
from xlrd import open_workbook # http://pypi.python.org/pypi/xlrd
from xlwt import easyxf # http://pypi.python.org/pypi/xlwt

file_path = 'C:\Dev\Test_upd.xls'
rb = open_workbook('C:\Dev\Test.xls',formatting_info=True)
r_sheet = rb.sheet_by_index(0) # read only copy to introspect the file
wb = copy(rb) # a writable copy (I can't read values out of this, only write to it)
w_sheet = wb.get_sheet(0) # the sheet to write to within the writable copy
w_sheet.write(1, 1, 'Value')
wb.save(file_path)

I attached the file here: http://ifolder.su/43507580

Write to [email protected] if it got expired.

P.S.: Some functions are not called in the dummy example, so maybe they will need for an adaptation also. Who wants to do it, fix exceptions one-by-one with a google help. It's not a very difficult task, because the package code is small...

You can't use a variable in an IN clause - you need to use dynamic SQL, or use a function (TSQL or CLR) to convert the list of values into a table.

Dynamic SQL example:

DECLARE @ExcludedList VARCHAR(MAX)
    SET @ExcludedList = 3 + ',' + 4 + ',' + '22'

DECLARE @SQL NVARCHAR(4000)
    SET @SQL = 'SELECT * FROM A WHERE Id NOT IN (@ExcludedList) '

 BEGIN

   EXEC sp_executesql @SQL '@ExcludedList VARCHAR(MAX)' @ExcludedList

 END

From the GNU UPC website:

Compiler build fails with fatal error: gnu/stubs-32.h: No such file or directory

This error message shows up on the 64 bit systems where GCC/UPC multilib feature is enabled, and it indicates that 32 bit version of libc is not installed. There are two ways to correct this problem:

• Install 32 bit version of glibc (e.g. glibc-devel.i686 on Fedora, CentOS, ..)
• Disable 'multilib' build by supplying "--disable-multilib" switch on the compiler configuration command

I'll break this down in to several distinct parts, as each part can be done individually. (I see the similar answer, but I'm going to give a more detailed explanation here..)

First part, in order to avoid typing "CScript" (or "WScript"), you need to tell Windows how to launch a * .vbs script file. In My Windows 8 (I cannot be sure all these commands work exactly as shown here in older Windows, but the process is the same, even if you have to change the commands slightly), launch a console window (aka "command prompt", or aka [incorrectly] "dos prompt") and type "assoc .vbs". That should result in a response such as:

C:\Windows\System32>assoc .vbs
.vbs=VBSFile

Using that, you then type "ftype VBSFile", which should result in a response of:

C:\Windows\System32>ftype VBSFile
vbsfile="%SystemRoot%\System32\WScript.exe" "%1" %*

-OR-

C:\Windows\System32>ftype VBSFile
vbsfile="%SystemRoot%\System32\CScript.exe" "%1" %*

If these two are already defined as above, your Windows' is already set up to know how to launch a * .vbs file. (BTW, WScript and CScript are the same program, using different names. WScript launches the script as if it were a GUI program, and CScript launches it as if it were a command line program. See other sites and/or documentation for these details and caveats.)

If either of the commands did not respond as above (or similar responses, if the file type reported by assoc and/or the command executed as reported by ftype have different names or locations), you can enter them yourself:

C:\Windows\System32>assoc .vbs=VBSFile

-and/or-

C:\Windows\System32>ftype vbsfile="%SystemRoot%\System32\WScript.exe" "%1" %*

You can also type "help assoc" or "help ftype" for additional information on these commands, which are often handy when you want to automatically run certain programs by simply typing a filename with a specific extension. (Be careful though, as some file extensions are specially set up by Windows or programs you may have installed so they operate correctly. Always check the currently assigned values reported by assoc/ftype and save them in a text file somewhere in case you have to restore them.)

Second part, avoiding typing the file extension when typing the command from the console window.. Understanding how Windows (and the CMD.EXE program) finds commands you type is useful for this (and the next) part. When you type a command, let's use "querty" as an example command, the system will first try to find the command in it's internal list of commands (via settings in the Windows' registry for the system itself, or programmed in in the case of CMD.EXE). Since there is no such command, it will then try to find the command in the current %PATH% environment variable. In older versions of DOS/Windows, CMD.EXE (and/or COMMAND.COM) would automatically add the file extensions ".bat", ".exe", ".com" and possibly ".cmd" to the command name you typed, unless you explicitly typed an extension (such as "querty.bat" to avoid running "querty.exe" by mistake). In more modern Windows, it will try the extensions listed in the %PATHEXT% environment variable. So all you have to do is add .vbs to %PATHEXT%. For example, here's my %PATHEXT%:

C:\Windows\System32>set pathext
PATHEXT=.PLX;.PLW;.PL;.BAT;.CMD;.VBS;.COM;.EXE;.VBE;.JS;.JSE;.WSF;.WSH;.MSC;.PY

Notice that the extensions MUST include the ".", are separated by ";", and that .VBS is listed AFTER .CMD, but BEFORE .COM. This means that if the command processor (CMD.EXE) finds more than one match, it'll use the first one listed. That is, if I have query.cmd, querty.vbs and querty.com, it'll use querty.cmd.

Now, if you want to do this all the time without having to keep setting %PATHEXT%, you'll have to modify the system environment. Typing it in a console window only changes it for that console window session. I'll leave this process as an exercise for the reader. :-P

Third part, getting the script to run without always typing the full path. This part, in relation to the second part, has been around since the days of DOS. Simply make sure the file is in one of the directories (folders, for you Windows' folk!) listed in the %PATH% environment variable. My suggestion is to make your own directory to store various files and programs you create or use often from the console window/command prompt (that is, don't worry about doing this for programs you run from the start menu or any other method.. only the console window. Don't mess with programs that are installed by Windows or an automated installer unless you know what you're doing).

Personally, I always create a "C:\sys\bat" directory for batch files, a "C:\sys\bin" directory for * .exe and * .com files (for example, if you download something like "md5sum", a MD5 checksum utility), a "C:\sys\wsh" directory for VBScripts (and JScripts, named "wsh" because both are executed using the "Windows Scripting Host", or "wsh" program), and so on. I then add these to my system %PATH% variable (Control Panel -> Advanced System Settings -> Advanced tab -> Environment Variables button), so Windows can always find them when I type them.

Combining all three parts will result in configuring your Windows system so that anywhere you can type in a command-line command, you can launch your VBScript by just typing it's base file name. You can do the same for just about any file type/extension; As you probably saw in my %PATHEXT% output, my system is set up to run Perl scripts (.PLX;.PLW;.PL) and Python (.PY) scripts as well. (I also put "C:\sys\bat;C:\sys\scripts;C:\sys\wsh;C:\sys\bin" at the front of my %PATH%, and put various batch files, script files, et cetera, in these directories, so Windows can always find them. This is also handy if you want to "override" some commands: Putting the * .bat files first in the path makes the system find them before the * .exe files, for example, and then the * .bat file can launch the actual program by giving the full path to the actual *. exe file. Check out the various sites on "batch file programming" for details and other examples of the power of the command line.. It isn't dead yet!)

One final note: DO check out some of the other sites for various warnings and caveats. This question posed a script named "converter.vbs", which is dangerously close to the command "convert.exe", which is a Windows program to convert your hard drive from a FAT file system to a NTFS file system.. Something that can clobber your hard drive if you make a typing mistake!

On the other hand, using the above techniques you can insulate yourself from such mistakes, too. Using CONVERT.EXE as an example.. Rename it to something like "REAL_CONVERT.EXE", then create a file like "C:\sys\bat\convert.bat" which contains:

@ECHO OFF
ECHO !DANGER! !DANGER! !DANGER! !DANGER, WILL ROBINSON!

ECHO This command will convert your hard drive to NTFS! DO YOU REALLY WANT TO DO THIS?!
ECHO PRESS CONTROL-C TO ABORT, otherwise..

REM "PAUSE" will pause the batch file with the message "Press any key to continue...",
REM and also allow the user to press CONTROL-C which will prompt the user to abort or
REM continue running the batch file.
PAUSE

ECHO Okay, if you're really determined to do this, type this command:
ECHO.    %SystemRoot%\SYSTEM32\REAL_CONVERT.EXE
ECHO to run the real CONVERT.EXE program. Have a nice day!

You can also use CHOICE.EXE in modern Windows to make the user type "y" or "n" if they really want to continue, and so on.. Again, the power of batch (and scripting) files!

Here's some links to some good resources on how to use all this power:

http://ss64.com/

http://www.computerhope.com/batch.htm

http://commandwindows.com/batch.htm

http://www.robvanderwoude.com/batchfiles.php

Most of these sites are geared towards batch files, but most of the information in them applies to running any kind of batch (* .bat) file, command (* .cmd) file, and scripting (* .vbs, * .js, * .pl, * .py, and so on) files.

Assume you stored that dictionary in a variable called values. To get id in to a variable, do:

idValue = values['criteria'][0]['id']

If that json is in a file, do the following to load it:

import json
jsonFile = open('your_filename.json', 'r')
values = json.load(jsonFile)
jsonFile.close()

If that json is from a URL, do the following to load it:

import urllib, json
f = urllib.urlopen("http://domain/path/jsonPage")
values = json.load(f)
f.close()

To print ALL of the criteria, you could:

for criteria in values['criteria']:
    for key, value in criteria.iteritems():
        print key, 'is:', value
    print ''

For those coming from another language like me, maybe with a simple loop it's easier to understand and use it:

mylist = ["foo", "bar", "baz", "bar"]
newlist = enumerate(mylist)
for index, item in newlist:
  if item == "bar":
    print(index, item)

I am thankful for So what exactly does enumerate do?. That helped me to understand.

I know that this is an old question but I am just going to place this here:

To prevent skype from using port 80 and port 443, open the Skype window, then click on the Tools menu and select Options.
Click on the Advanced tab, and go to the Connection sub-tab.
Uncheck the checkbox for Use port 80 and 443 as an alternative for additional incoming connections option.
Click on the Save button and then restart Skype.
After you restart skype, skype wont use port 88 or 443 anymore.

Hope this might help someone.

I'm mostly agree with chosen answer (https://stackoverflow.com/a/12857584/871392), but want to add option in Making Queries section.

One can define QuerySet classes for models for make filter queries and so on. After that you can proxy this queryset class for model's manager, like build-in Manager and QuerySet classes do.

Although, if you had to query several data models to get one domain model, it seems more reasonable to me to put this in separate module like suggested before.

"W7 prompts everytime to run this program "devenv.exe" , anyway to get rid of that ?"

Yes. You can prevent Windows from prompting you by going to Control Panel/User Accounts/Change User Account Control settings and move the slider down.

It seems you could simply go with

awk '{print $1 " " $2}' file

This prints the two first fields of each line in your input file, separated with a space.

You could hide them via css:

#example_info, #example_filter{display: none}

You don't need underscore, just use built-in map:

var string = 'Hello World!';_x000D_
_x000D_
document.write(string.split('').map(function(c) { return c.charCodeAt(); }));

Pass your object via Parcelable. And here is a good tutorial to get you started.
First Question should implements Parcelable like this and add the those lines:

public class Question implements Parcelable{
    public Question(Parcel in) {
        // put your data using = in.readString();
  this.operands = in.readString();;
    this.choices = in.readString();;
    this.userAnswerIndex = in.readString();;

    }

    public Question() {
    }

    @Override
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(operands);
        dest.writeString(choices);
        dest.writeString(userAnswerIndex);
    }

    public static final Parcelable.Creator<Question> CREATOR = new Parcelable.Creator<Question>() {

        @Override
        public Question[] newArray(int size) {
            return new Question[size];
        }

        @Override
        public Question createFromParcel(Parcel source) {
            return new Question(source);
        }
    };

}

Then pass your data like this:

Question question = new Question();
// put your data
  Intent resultIntent = new Intent(this, ResultActivity.class);
  resultIntent.putExtra("QuestionsExtra", question);
  startActivity(resultIntent);

And get your data like this:

Question question = new Question();
Bundle extras = getIntent().getExtras();
if(extras != null){
    question = extras.getParcelable("QuestionsExtra");
}

This will do!

i tend to use this calculation a lot in things i make, so i like to add it to the Math object:

Math.dist=function(x1,y1,x2,y2){ 
  if(!x2) x2=0; 
  if(!y2) y2=0;
  return Math.sqrt((x2-x1)*(x2-x1)+(y2-y1)*(y2-y1)); 
}
Math.dist(0,0, 3,4); //the output will be 5
Math.dist(1,1, 4,5); //the output will be 5
Math.dist(3,4); //the output will be 5

Update:

this approach is especially happy making when you end up in situations something akin to this (i often do):

varName.dist=Math.sqrt( ( (varName.paramX-varX)/2-cx )*( (varName.paramX-varX)/2-cx ) + ( (varName.paramY-varY)/2-cy )*( (varName.paramY-varY)/2-cy ) );

that horrid thing becomes the much more manageable:

varName.dist=Math.dist((varName.paramX-varX)/2, (varName.paramY-varY)/2, cx, cy);

Click Your app from Xcode Under Targets. (Under project.) Here you see Summary info, build settings, Build phases, build rules.

Okay go to Build Settings. Go down to Code Signing.

You see you have two fields Debug and Release. You have two profiles to choose from in each of those fields, Distributing and developing.

Let distributing be the one from the Release field. Let Developing be the one from the Debug field.

Doing this solved this problem, and let that error message go away. Now I can run my application fine.

Linkage determines whether identifiers that have identical names refer to the same object, function, or other entity, even if those identifiers appear in different translation units. The linkage of an identifier depends on how it was declared. There are three types of linkages:

1. Internal linkage : identifiers can only be seen within a translation unit.
2. External linkage : identifiers can be seen (and referred to) in other translation units.
3. No linkage : identifiers can only be seen in the scope in which they are defined. Linkage does not affect scoping

C++ only : You can also have linkage between C++ and non-C++ code fragments, which is called language linkage.

Depending on your language, there may be a to_json method available. That will escape many things that break CSVs.

In a for-in-loop the running variable holds the property name, not the property value.

for (var counter in jsonData.counters) {
    console.log(jsonData.counters[counter].counter_name);
}

But as counters is an Array, you have to use a normal for-loop:

for (var i=0; i<jsonData.counters.length; i++) {
    var counter = jsonData.counters[i];
    console.log(counter.counter_name);
}
