Whether a value in an int is signed or unsigned depends on how the bits are interpreted - Java interprets bits as a signed value (it doesn't have unsigned primitives).

If you have an int that you want to interpret as an unsigned value (e.g. you read an int from a DataInputStream that you know should be interpreted as an unsigned value) then you can do the following trick.

int fourBytesIJustRead = someObject.getInt();
long unsignedValue = fourBytesIJustRead & 0xffffffffL;

Note, that it is important that the hex literal is a long literal, not an int literal - hence the 'L' at the end.

I have faced this error, Previous I had push in root directory, and now I have push another directory, so I could be remove this error and run below commands.

git add .
git commit -m "some comments"
git push --set-upstream origin master

You could also configure mongod to run on start up so that it is automatically running on start up and the dbpath is set upon configuration. To do this try:

mongod --smallfiles --config /etc/mongod.conf

The --smallfiles tag is there in case you get an error with size. It is, of course, optional. Doing this should solve your problem while also automating your mongodb setup.

Inserting at a specific index (rather than, say, at the first space character) has to use string slicing/substring:

var txt2 = txt1.slice(0, 3) + "bar" + txt1.slice(3);

Pretty simple method is to just pass the creds in the url, can be slightly suspect though - use with caution.

import os

def getRepo(repo_url, login_object):
  '''
  Clones the passed repo to my staging dir
  '''

  path_append = r"stage\repo" # Can set this as an arg 
  os.chdir(path_append)

  repo_moddedURL = 'https://' + login_object['username'] + ':' + login_object['password'] + '@github.com/UserName/RepoName.git'
  os.system('git clone '+ repo_moddedURL)

  print('Cloned!')


if __name__ == '__main__':
    getRepo('https://github.com/UserName/RepoYouWant.git', {'username': 'userName', 'password': 'passWord'})

It depends. If it's a dynamically allocated array, that is, you created it calling malloc, then as others suggest you must either save the size of the array/number of elements somewhere or have a sentinel (a struct with a special value, that will be the last one).

If it's a static array, you can sizeof it's size/the size of one element. For example:

int array[10], array_size;
...
array_size = sizeof(array)/sizeof(int);

Note that, unless it's global, this only works in the scope where you initialized the array, because if you past it to another function it gets decayed to a pointer.

Hope it helps.

use them in Java code like this:

 color = getResources().getColor(R.color.mycolor);

The getResources() method returns the ResourceManager class for the current activity, and getColor() asks the manager to look up a color given a resource ID

You will have to open the file in one way or another if you want to access the data within it. Obviously, one way is to open it in your Excel application instance, e.g.:-

(untested code)

Dim wbk As Workbook
Set wbk = Workbooks.Open("C:\myworkbook.xls")

' now you can manipulate the data in the workbook anyway you want, e.g. '

Dim x As Variant
x = wbk.Worksheets("Sheet1").Range("A6").Value

Call wbk.Worksheets("Sheet2").Range("A1:G100").Copy
Call ThisWorbook.Worksheets("Target").Range("A1").PasteSpecial(xlPasteValues)
Application.CutCopyMode = False

' etc '

Call wbk.Close(False)

Another way to do it would be to use the Excel ADODB provider to open a connection to the file and then use SQL to select data from the sheet you want, but since you are anyway working from within Excel I don't believe there is any reason to do this rather than just open the workbook. Note that there are optional parameters for the Workbooks.Open() method to open the workbook as read-only, etc.

You are very close; currently you compare the row[2] with integer 0, make the comparison with the string "0". When you read the data from a file, it is a string and not an integer, so that is why your integer check fails currently:

row[2]!="0":

Also, you can use the with keyword to make the current code slightly more pythonic so that the lines in your code are reduced and you can omit the .close statements:

import csv
with open('first.csv', 'rb') as inp, open('first_edit.csv', 'wb') as out:
    writer = csv.writer(out)
    for row in csv.reader(inp):
        if row[2] != "0":
            writer.writerow(row)

Note that input is a Python builtin, so I've used another variable name instead.

Edit: The values in your csv file's rows are comma and space separated; In a normal csv, they would be simply comma separated and a check against "0" would work, so you can either use strip(row[2]) != 0, or check against " 0".

The better solution would be to correct the csv format, but in case you want to persist with the current one, the following will work with your given csv file format:

$ cat test.py 
import csv
with open('first.csv', 'rb') as inp, open('first_edit.csv', 'wb') as out:
    writer = csv.writer(out)
    for row in csv.reader(inp):
        if row[2] != " 0":
            writer.writerow(row)
$ cat first.csv 
6.5, 5.4, 0, 320
6.5, 5.4, 1, 320
$ python test.py 
$ cat first_edit.csv 
6.5, 5.4, 1, 320

Just for the record, I got borders in the table and to get rid of it I needed to set following properties in the GridView:

GridLines="None"
CellSpacing="-1"

Here is another solution using Lodash:

var _ = require('lodash');

var result1 = [
    {id:1, name:'Sandra', type:'user', username:'sandra'},
    {id:2, name:'John', type:'admin', username:'johnny2'},
    {id:3, name:'Peter', type:'user', username:'pete'},
    {id:4, name:'Bobby', type:'user', username:'be_bob'}
];

var result2 = [
    {id:2, name:'John', email:'[email protected]'},
    {id:4, name:'Bobby', email:'[email protected]'}
];

// filter all those that do not match
var result = types1.filter(function(o1){
    // if match found return false
    return _.findIndex(types2, {'id': o1.id, 'name': o1.name}) !== -1 ? false : true;
});

console.log(result);

ls -lh file.txt | awk '{ print $5 }'

Simple socket server app example

I've already posted a client example at: https://stackoverflow.com/a/35971718/895245 , so here goes a server example.

This example app runs a server that returns a ROT-1 cypher of the input.

You would then need to add an Exit button + some sleep delays, but this should get you started.

To play with it:

• install the app
• get your phone and PC on a LAN
• find your phone's IP with https://android.stackexchange.com/a/130468/126934
• run netcat $PHONE_IP 12345
• type some lines

Android sockets are the same as Java's, except we have to deal with some permission issues.

This is useful concept for recursion without static properties , reference etc:

function getRecursiveItems($id){
    $allItems = array();
    
    function getItems($parent_id){
       return DB::findAll()->where('`parent_id` = $parent_id');
    } 
   
    foreach(getItems($id) as $item){
         $allItems = array_merge($allItems, getItems($item->id) );
    }

    return $allItems;
}

You may use jupyter magic command as below

%cd "C:\abc\xyz\"

The best way is to close the session is: if there is no response for that session after particular interval of time. then close. Please see this post and I hope it will resolve the issue. "How to change the session timeout in PHP?"

You can't redirect to a function. What you can do is pass some flag on the URL when redirecting, then check that flag in the server side code and if raised, execute the function.

For example:

document.location = "MyPage.php?action=DoThis";

Then in your PHP code check for "action" in the query string and if equal to "DoThis" execute whatever function you need.

I found one solution and it does not require to define runnable or other things and it's working fine.

    var lastTouchTime: Long = 0

    // ( ViewConfiguration.#.DEFAULT_LONG_PRESS_TIMEOUT =500)
    val longPressTime = 500

    var lastTouchX = 0f
    var lastTouchY = 0f

    view.setOnTouchListener { v, event ->

        when (event.action) {
            MotionEvent.ACTION_DOWN -> {
                lastTouchTime = SystemClock.elapsedRealtime()
                lastTouchX = event.x
                lastTouchY = event.y
                return@setOnTouchListener true
            }
            MotionEvent.ACTION_UP -> {
                if (SystemClock.elapsedRealtime() - lastTouchTime > longPressTime
                        && Math.abs(event.x - lastTouchX) < 3
                        && Math.abs(event.y - lastTouchY) < 3) {
                    Log.d(TAG, "Long press")
                }
                return@setOnTouchListener true
            }
            else -> {
                return@setOnTouchListener false
            }
        }

    }

For the general case of deeply nested lists with 3 or more levels like the ones obtained from a nested JSON:

{
"2015": {
  "spain": {"population": 43, "GNP": 9},
  "sweden": {"population": 7, "GNP": 6}},
"2016": {
  "spain": {"population": 45, "GNP": 10},
  "sweden": {"population": 9, "GNP": 8}}
}

consider the approach of melt() to convert the nested list to a tall format first:

myjson <- jsonlite:fromJSON(file("test.json"))
tall <- reshape2::melt(myjson)[, c("L1", "L2", "L3", "value")]
    L1     L2         L3 value
1 2015  spain population    43
2 2015  spain        GNP     9
3 2015 sweden population     7
4 2015 sweden        GNP     6
5 2016  spain population    45
6 2016  spain        GNP    10
7 2016 sweden population     9
8 2016 sweden        GNP     8

followed by dcast() then to wide again into a tidy dataset where each variable forms a a column and each observation forms a row:

wide <- reshape2::dcast(tall, L1+L2~L3) 
# left side of the formula defines the rows/observations and the 
# right side defines the variables/measurements
    L1     L2 GNP population
1 2015  spain   9         43
2 2015 sweden   6          7
3 2016  spain  10         45
4 2016 sweden   8          9

Follow the below steps:

1. Download and install from here. Double click and install it.
2. Select "View" -> "Show Expired Certificates" in Keychain app.
3. Remove Apple Worldwide Developer Relations Certificate Authority certificates from "login" tab and "System" tab in Keychain app.

If you don't find your WWDR certificate in Login or System tab, then select category "All items" on the left side. Most probably you will get to see an expired WWDR certificate here, and you can remove it. An expired certificate is always shown with a red asterisk.

Another option that may be useful is a dedicated HTTP debugging tool. There's a few available, I'd suggest HTTP Toolkit: an open-source project I've been working on (yeah, I might be biased) to solve this same problem for myself.

The main difference is usability & power. The Chrome dev tools are good for simple things, and I'd recommend starting there, but if you're struggling to understand the information there, and you need either more explanation or more power then proper focused tools can be useful!

For this case, it'll show you the full POST body you're looking for, with a friendly editor and highlighting (all powered by VS Code) so you can dig around. It'll give you the request & response headers of course, but with extra info like docs from MDN (the Mozilla Developer Network) for every standard header and status code you can see.

A picture is worth a thousand StackOverflow answers:

Try COALESCE. It returns the first non-NULL value.

SELECT COALESCE(`prereq`, ' ') FROM `test`

My solution hides keyboard on outside click in any activity, with of all edit texts. Without specifying them one by one.

First add to root view of layout xml: android:clickable="true" android:focusableInTouchMode="true"

Next, create one parent Acitvity of all activities you want to hide keyboard, and specify onResume() method:

 @Override
    protected void onResume() {
        super.onResume();
        //getting Root View that gets focus
        View rootView =((ViewGroup)findViewById(android.R.id.content)).
                getChildAt(0);
        rootView.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus) {
                    hideKeyboard(AbstractActivity.this);
                }
            }
        });
    }

Extend your activity with this General activity (Inheritance power !) and that's all, every time any EditText (on any extended Activity) will lose focus, keyboard will be hidden.

P.S. hideKeyboard method :

public static void hideKeyboard(Activity context) {
    InputMethodManager inputMethodManager = (InputMethodManager) context.getSystemService(Activity.INPUT_METHOD_SERVICE);
    inputMethodManager.hideSoftInputFromWindow( context.getCurrentFocus().getWindowToken(), 0);
}

context.getCurrentFocus() doesn't need specifying specific EditText view..

This should do what you want:

print tempfile.gettempdir()

For me on my Windows box, I get:

c:\temp

and on my Linux box I get:

/tmp

This example uses regex_search to perform a substring search.

- name: make conditional variable
  command: "file -s /dev/xvdf"
  register: fsm_out

- name: makefs
  command: touch "/tmp/condition_satisfied"
  when: fsm_out.stdout | regex_search(' data')

ansible version: 2.4.3.0

you just run adb uninstall {{package_name}}. That's it. Now you try the build.

0) go to phpmyadmin don't select any db
1) Click "Privileges". You'll see all the users on MySQL's privilege tables.
2) Check the user "root" whose Host value is localhost, and click the "Edit Privileges" icon.
3) In the "Change password" field, click "Password" and enter a new password.
4) Retype the password to confirm. Then click "Go" to apply the settings.

you have to do it in that way:

$('#datepicker').datepicker('clearDates');

var datos = $("#id_formulario").serialize();
$.ajax({         
    url: "url.php",      
    type: "POST",                   
    dataType: "html",                 
    data: datos,                 
    success: function (prueba) { 
        alert("funciona!");
    }//FIN SUCCES

});//FIN  AJAX

getElementById returns a reference to the element using its id. The element is the input in the first case and the paragraph in the second case.

https://developer.mozilla.org/en-US/docs/Web/API/document.getElementById

Python3

use

from .user import User inside dir.py file

and

use from class.dir import Dir inside main.py
or from class.usr import User inside main.py

like so

it doenst work for me but it prints the correct element to the console

this is the code:

function click(x, y)
{
    var ev = new MouseEvent('click', {
        'view': window,
        'bubbles': true,
        'cancelable': true,
        'screenX': x,
        'screenY': y
    });

    var el = document.elementFromPoint(x, y);
    console.log(el); //print element to console
    el.dispatchEvent(ev);
}
click(400, 400);

Or.. Pattern#quote:

String[] value_split = rat_values.split(Pattern.quote("|"));

This is happening because String#split accepts a regex:

| has a special meaning in regex.

quote will return a String representation for the regex.

Here's the simple, built-in way:

<span title="My tip">text</span>

That gives you plain text tooltips. If you want rich tooltips, with formatted HTML in them, you'll need to use a library to do that. Fortunately there are loads of those.

The enumerate() function adds a counter to an iterable.

So for each element in cursor, a tuple is produced with (counter, element); the for loop binds that to row_number and row, respectively.

Demo:

>>> elements = ('foo', 'bar', 'baz')
>>> for elem in elements:
...     print elem
... 
foo
bar
baz
>>> for count, elem in enumerate(elements):
...     print count, elem
... 
0 foo
1 bar
2 baz

By default, enumerate() starts counting at 0 but if you give it a second integer argument, it'll start from that number instead:

>>> for count, elem in enumerate(elements, 42):
...     print count, elem
... 
42 foo
43 bar
44 baz

If you were to re-implement enumerate() in Python, here are two ways of achieving that; one using itertools.count() to do the counting, the other manually counting in a generator function:

from itertools import count

def enumerate(it, start=0):
    # return an iterator that adds a counter to each element of it
    return zip(count(start), it)

and

def enumerate(it, start=0):
    count = start
    for elem in it:
        yield (count, elem)
        count += 1

The actual implementation in C is closer to the latter, with optimisations to reuse a single tuple object for the common for i, ... unpacking case and using a standard C integer value for the counter until the counter becomes too large to avoid using a Python integer object (which is unbounded).

I had the same issue. For me it helped to remove the .vs directory in the project folder.

Using numpy version 1.10.4 and pandas version 0.17.1,

dates = np.array(['2010-10-17', '2011-05-13', '2012-01-15'], dtype=np.datetime64)
pd.to_datetime(dates).year

I get what you're looking for:

array([2010, 2011, 2012], dtype=int32)

You can join all regular expressions into single one. This way the string is scanned only once. Even with a sligthly more complex regular expression.

var thisExpressions = [ /something/, /something_else/, /and_something_else/];
var thisString = 'else';


function matchInArray(str, expr) {
    var fullExpr = new RegExp(expr
        .map(x=>x.source) // Just if you need to provide RegExp instances instead of strings or ...
        // .map(x=>x.substring(1, x.length -2)  // ...if you need to provide strings enclosed by "/" like in original question.
        .join("|")
    )
    return str.match(fullExpr);

};


if (matchInArray(thisString, thisExpressions)) {
    console.log ("Match!!");
} 

In fact, even with this approach, if you need check the same expression set against multiple strings, this is a few suboptimal because you are building (and compiling) the same regular expression each time the function is called.

Better approach would be to use a function builder like this:

var thisExpressions = [ /something/, /something_else/, /and_something_else/];
var thisString = 'else';

function matchInArray_builder(expr) {
    var fullExpr = new RegExp(expr
        .map(x=>x.source) // Just if you need to provide RegExp instances instead of strings or ...
        // .map(x=>x.substring(1, x.length -2)  // ...if you need to provide strings enclosed by "/" like in original question.
        .join("|")
    )   

    return function (str) {
        return str.match(fullExpr);

    };
};  

var matchInArray = matchInArray_builder(thisExpressions);

if (matchInArray(thisString)) {
    console.log ("Match!!");
} 

Use a custom comparator:

Collections.sort(nodeList, new Comparator<DataNode>(){
     public int compare(DataNode o1, DataNode o2){
         if(o1.degree == o2.degree)
             return 0;
         return o1.degree < o2.degree ? -1 : 1;
     }
});

Try crypto.randomBytes():

require('crypto').randomBytes(48, function(err, buffer) {
  var token = buffer.toString('hex');
});

The 'hex' encoding works in node v0.6.x or newer.

def train_val_test_split(X, y, train_size, val_size, test_size):

The formats and codecs supported by your build of ffmpeg can vary due the version, how it was compiled, and if any external libraries, such as libx264, were supported during compilation.

Formats (muxers and demuxers):

List all formats:

ffmpeg -formats

Display options specific to, and information about, a particular muxer:

ffmpeg -h muxer=matroska

Display options specific to, and information about, a particular demuxer:

ffmpeg -h demuxer=gif

Codecs (encoders and decoders):

List all codecs:

ffmpeg -codecs

List all encoders:

ffmpeg -encoders

List all decoders:

ffmpeg -decoders

Display options specific to, and information about, a particular encoder:

ffmpeg -h encoder=mpeg4

Display options specific to, and information about, a particular decoder:

ffmpeg -h decoder=aac

Reading the results

There is a key near the top of the output that describes each letter that precedes the name of the format, encoder, decoder, or codec:

$ ffmpeg -encoders
[…]
Encoders:
 V..... = Video
 A..... = Audio
 S..... = Subtitle
 .F.... = Frame-level multithreading
 ..S... = Slice-level multithreading
 ...X.. = Codec is experimental
 ....B. = Supports draw_horiz_band
 .....D = Supports direct rendering method 1
 ------
[…]
 V.S... mpeg4                MPEG-4 part 2

In this example V.S... indicates that the encoder mpeg4 is a Video encoder and supports Slice-level multithreading.

What is a codec and how does it differ from a format?

The 'c' means it's a character special file.

You can also pipe commands inside Docker container, bash -c "<command1> | <command2>" for example:

docker run img /bin/bash -c "ls -1 | wc -l"

But, without invoking the shell in the remote the output will be redirected to the local terminal.

Here is a solution to getting an array (list) of bytes:

I found that you needed to convert the Int to a byte first, before passing it to the bytes():

bytes(int('0xA2', 16).to_bytes(1, "big"))

Then create a list from the bytes:

list(frame)

So your code should look like:

frame = b""
frame += bytes(int('0xA2', 16).to_bytes(1, "big"))
frame += bytes(int('0x01', 16).to_bytes(1, "big"))
frame += bytes(int('0x02', 16).to_bytes(1, "big"))
frame += bytes(int('0x03', 16).to_bytes(1, "big"))
frame += bytes(int('0x04', 16).to_bytes(1, "big"))
bytesList = list(frame)

The question was for an array (list) of bytes. You accepted an answer that doesn't tell how to get a list so I'm not sure if this is actually what you needed.

You can calculate the checksum of a file by reading the binary data and using hashlib.md5().hexdigest(). A function to do this would look like the following:

def File_Checksum_Dis(dirname):
    
    if not os.path.exists(dirname):
        print(dirname+" directory is not existing");
    
    for fname in os.listdir(dirname):
        if not fname.endswith('~'):
            fnaav = os.path.join(dirname, fname);
            fd = open(fnaav, 'rb');
            data = fd.read();
            fd.close();
        
            print("-"*70);
            print("File Name is: ",fname);          
            print(hashlib.md5(data).hexdigest())
            print("-"*70);

Using CentOS Linux I found that the easiest syntax would be:

where "link" is the web address you want to save and "file.ext" is the filename and extension of your choice.

Topic is old but for future readers:

This feature is tightly related to Discriminated Unions which is not implemented in C# so far. I found its issue here:

https://github.com/dotnet/csharplang/issues/113

This issue is still open and feature has been planned for C# 10

So still we have to wait a bit more, but after releasing you can do it this way:

static bool IntegerFunction<T>(T value) where T : Int16 | Int32 | Int64 | ...

Another alternative is to use a lambda:

ent.bind("<Return>", (lambda event: name_of_function()))

Full code:

from tkinter import *
from tkinter.messagebox import showinfo

def reply(name):
    showinfo(title="Reply", message = "Hello %s!" % name)


top = Tk()
top.title("Echo")
top.iconbitmap("Iconshock-Folder-Gallery.ico")

Label(top, text="Enter your name:").pack(side=TOP)
ent = Entry(top)
ent.bind("<Return>", (lambda event: reply(ent.get())))
ent.pack(side=TOP)
btn = Button(top,text="Submit", command=(lambda: reply(ent.get())))
btn.pack(side=LEFT)

top.mainloop()

As you can see, creating a lambda function with an unused variable "event" solves the problem.

Launch4j

Launch4j is a cross-platform tool for wrapping Java applications distributed as jars in lightweight Windows native executables. The executable can be configured to search for a certain JRE version or use a bundled one, and it's possible to set runtime options, like the initial/max heap size. The wrapper also provides better user experience through an application icon, a native pre-JRE splash screen, a custom process name, and a Java download page in case the appropriate JRE cannot be found.

You just said javascript in your tags, so @Wampie Driessen post could helps you.

I want also to contribute, so you can use the following when using jQuery if you need it.

 //Firefox
 $('#elem').bind('DOMMouseScroll', function(e){
     if(e.detail > 0) {
         //scroll down
         console.log('Down');
     }else {
         //scroll up
         console.log('Up');
     }

     //prevent page fom scrolling
     return false;
 });

 //IE, Opera, Safari
 $('#elem').bind('mousewheel', function(e){
     if(e.wheelDelta< 0) {
         //scroll down
         console.log('Down');
     }else {
         //scroll up
         console.log('Up');
     }

     //prevent page fom scrolling
     return false;
 });

Another example:

$(function(){
    var _top = $(window).scrollTop();
    var _direction;
    $(window).scroll(function(){
        var _cur_top = $(window).scrollTop();
        if(_top < _cur_top)
        {
            _direction = 'down';
        }
        else
        {
            _direction = 'up';
        }
        _top = _cur_top;
        console.log(_direction);
    });
});?

I wrote this answer back in '09 when Android was relatively new, and there were many not well established areas in Android development. I have added a long addendum at the bottom of this post, addressing some criticism, and detailing a philosophical disagreement I have with the use of Singletons rather than subclassing Application. Read it at your own risk.

ORIGINAL ANSWER:

The more general problem you are encountering is how to save state across several Activities and all parts of your application. A static variable (for instance, a singleton) is a common Java way of achieving this. I have found however, that a more elegant way in Android is to associate your state with the Application context.

As you know, each Activity is also a Context, which is information about its execution environment in the broadest sense. Your application also has a context, and Android guarantees that it will exist as a single instance across your application.

The way to do this is to create your own subclass of android.app.Application, and then specify that class in the application tag in your manifest. Now Android will automatically create an instance of that class and make it available for your entire application. You can access it from any context using the Context.getApplicationContext() method (Activity also provides a method getApplication() which has the exact same effect). Following is an extremely simplified example, with caveats to follow:

class MyApp extends Application {

  private String myState;

  public String getState(){
    return myState;
  }
  public void setState(String s){
    myState = s;
  }
}

class Blah extends Activity {

  @Override
  public void onCreate(Bundle b){
    ...
    MyApp appState = ((MyApp)getApplicationContext());
    String state = appState.getState();
    ...
  }
}

This has essentially the same effect as using a static variable or singleton, but integrates quite well into the existing Android framework. Note that this will not work across processes (should your app be one of the rare ones that has multiple processes).

Something to note from the example above; suppose we had instead done something like:

class MyApp extends Application {

  private String myState = /* complicated and slow initialization */;

  public String getState(){
    return myState;
  }
}

Now this slow initialization (such as hitting disk, hitting network, anything blocking, etc) will be performed every time Application is instantiated! You may think, well, this is only once for the process and I'll have to pay the cost anyways, right? For instance, as Dianne Hackborn mentions below, it is entirely possible for your process to be instantiated -just- to handle a background broadcast event. If your broadcast processing has no need for this state you have potentially just done a whole series of complicated and slow operations for nothing. Lazy instantiation is the name of the game here. The following is a slightly more complicated way of using Application which makes more sense for anything but the simplest of uses:

class MyApp extends Application {

  private MyStateManager myStateManager = new MyStateManager();

  public MyStateManager getStateManager(){
    return myStateManager ;
  }
}

class MyStateManager {

  MyStateManager() {
    /* this should be fast */
  }

  String getState() {
    /* if necessary, perform blocking calls here */
    /* make sure to deal with any multithreading/synchronicity issues */

    ...

    return state;
  }
}

class Blah extends Activity {

  @Override
  public void onCreate(Bundle b){
    ...
    MyStateManager stateManager = ((MyApp)getApplicationContext()).getStateManager();
    String state = stateManager.getState();
    ...
  }
}

While I prefer Application subclassing to using singletons here as the more elegant solution, I would rather developers use singletons if really necessary over not thinking at all through the performance and multithreading implications of associating state with the Application subclass.

NOTE 1: Also as anticafe commented, in order to correctly tie your Application override to your application a tag is necessary in the manifest file. Again, see the Android docs for more info. An example:

<application
     android:name="my.application.MyApp" 
     android:icon="..."
     android:label="...">
</application>

NOTE 2: user608578 asks below how this works with managing native object lifecycles. I am not up to speed on using native code with Android in the slightest, and I am not qualified to answer how that would interact with my solution. If someone does have an answer to this, I am willing to credit them and put the information in this post for maximum visibility.

ADDENDUM:

As some people have noted, this is not a solution for persistent state, something I perhaps should have emphasized more in the original answer. I.e. this is not meant to be a solution for saving user or other information that is meant to be persisted across application lifetimes. Thus, I consider most criticism below related to Applications being killed at any time, etc..., moot, as anything that ever needed to be persisted to disk should not be stored through an Application subclass. It is meant to be a solution for storing temporary, easily re-creatable application state (whether a user is logged in for example) and components which are single instance (application network manager for example) (NOT singleton!) in nature.

Dayerman has been kind enough to point out an interesting conversation with Reto Meier and Dianne Hackborn in which use of Application subclasses is discouraged in favor of Singleton patterns. Somatik also pointed out something of this nature earlier, although I didn't see it at the time. Because of Reto and Dianne's roles in maintaining the Android platform, I cannot in good faith recommend ignoring their advice. What they say, goes. I do wish to disagree with the opinions, expressed with regards to preferring Singleton over Application subclasses. In my disagreement I will be making use of concepts best explained in this StackExchange explanation of the Singleton design pattern, so that I do not have to define terms in this answer. I highly encourage skimming the link before continuing. Point by point:

Dianne states, "There is no reason to subclass from Application. It is no different than making a singleton..." This first claim is incorrect. There are two main reasons for this. 1) The Application class provides a better lifetime guarantee for an application developer; it is guaranteed to have the lifetime of the application. A singleton is not EXPLICITLY tied to the lifetime of the application (although it is effectively). This may be a non-issue for your average application developer, but I would argue this is exactly the type of contract the Android API should be offering, and it provides much more flexibility to the Android system as well, by minimizing the lifetime of associated data. 2) The Application class provides the application developer with a single instance holder for state, which is very different from a Singleton holder of state. For a list of the differences, see the Singleton explanation link above.

Dianne continues, "...just likely to be something you regret in the future as you find your Application object becoming this big tangled mess of what should be independent application logic." This is certainly not incorrect, but this is not a reason for choosing Singleton over Application subclass. None of Diane's arguments provide a reason that using a Singleton is better than an Application subclass, all she attempts to establish is that using a Singleton is no worse than an Application subclass, which I believe is false.

She continues, "And this leads more naturally to how you should be managing these things -- initializing them on demand." This ignores the fact that there is no reason you cannot initialize on demand using an Application subclass as well. Again there is no difference.

Dianne ends with "The framework itself has tons and tons of singletons for all the little shared data it maintains for the app, such as caches of loaded resources, pools of objects, etc. It works great." I am not arguing that using Singletons cannot work fine or are not a legitimate alternative. I am arguing that Singletons do not provide as strong a contract with the Android system as using an Application subclass, and further that using Singletons generally points to inflexible design, which is not easily modified, and leads to many problems down the road. IMHO, the strong contract the Android API offers to developer applications is one of the most appealing and pleasing aspects of programming with Android, and helped lead to early developer adoption which drove the Android platform to the success it has today. Suggesting using Singletons is implicitly moving away from a strong API contract, and in my opinion, weakens the Android framework.

Dianne has commented below as well, mentioning an additional downside to using Application subclasses, they may encourage or make it easier to write less performance code. This is very true, and I have edited this answer to emphasize the importance of considering perf here, and taking the correct approach if you're using Application subclassing. As Dianne states, it is important to remember that your Application class will be instantiated every time your process is loaded (could be multiple times at once if your application runs in multiple processes!) even if the process is only being loaded for a background broadcast event. It is therefore important to use the Application class more as a repository for pointers to shared components of your application rather than as a place to do any processing!

I leave you with the following list of downsides to Singletons, as stolen from the earlier StackExchange link:

• Inability to use abstract or interface classes;
• Inability to subclass;
• High coupling across the application (difficult to modify);
• Difficult to test (can't fake/mock in unit tests);
• Difficult to parallelize in the case of mutable state (requires extensive locking);

and add my own:

• Unclear and unmanageable lifetime contract unsuited for Android (or most other) development;

This solved my similar problem. I used it to revert the changes, then I added everything and commited changes in the terminal with

svn add folder_path/*
svn commit -m "message"

Hugogi Raudel has came up with an interesting way to to achieve this by CSS. suppose here is our HTML markup:

<ul>
  <li>1</li>
  <li>2</li>
  <li>3</li>
  <li>4</li>
  <li>5</li> 
  <li>6</li>
  <li>7</li>
  <li>8</li>
  <li>9</li>
</ul>

You can achieve a 3-row column using this CSS code:

li:nth-child(3n+2){
  margin: 120px 0 0 -110px;
}

li:nth-child(3n+3) {
  margin: 230px 0 0 -110px;
}

And here is the end result:

What we are doing here is adding a appropriate margin for each item in the row. This approach limitation is that you have to determine the column row count. it's not going to be dynamic. I'm sure it has use cases so I included this solution here.

• Here is a live demo: http://codepen.io/HugoGiraudel/pen/DoAIB
• You can read more on this in Hugo's blog post

You can set events on a combination of key and mouse events, and onblur as well, to be sure. In that event, store the value of the input. In the next call, compare the current value with the lastly stored value. Only do your magic if it has actually changed.

To do this in a more or less clean way:

You can associate data with a DOM element (lookup api.jquery.com/jQuery.data ) So you can write a generic set of event handlers that are assigned to all elements in the form. Each event can pass the element it was triggered by to one generic function. That one function can add the old value to the data of the element. That way, you should be able to implement this as a generic piece of code that works on your whole form and every form you'll write from now on. :) And it will probably take no more than about 20 lines of code, I guess.

An example is in this fiddle: http://jsfiddle.net/zeEwX/

Use

driver.findElement(By.linkText("App Configuration")).click()

Other Approaches will be

JavascriptLibrary jsLib = new JavascriptLibrary(); 
jsLib.callEmbeddedSelenium(selenium, "triggerMouseEventAt", elementToClick,"click", "0,0");

or

((JavascriptExecutor) driver).executeScript("arguments[0].click();", elementToClick);

You could use the following:

$('[element]').trigger('reset')

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

If you want to run some custom filter logic you can create a function which takes the array element as an argument and returns true or false based on whether it should be in the search results. Then pass it to the filter instruction just like you do with the search object, for example:

JS:

$scope.filterFn = function(car)
{
    // Do some tests

    if(car.carDetails.doors > 2)
    {
        return true; // this will be listed in the results
    }

    return false; // otherwise it won't be within the results
};

HTML:

...
<article data-ng-repeat="result in results | filter:search | filter:filterFn" class="result">
...

As you can see you can chain many filters together, so adding your custom filter function doesn't force you to remove the previous filter using the search object (they will work together seamlessly).

It's very simple. Just Set width of img to 100%

Just to update this thread, here is how to add a list (as a json array) into JSONObject. Plz substitute YourClass with your class name;

List<YourClass> list = new ArrayList<>();
JSONObject jsonObject = new JSONObject();

org.codehaus.jackson.map.ObjectMapper();
org.codehaus.jackson.JsonNode listNode = objectMapper.valueToTree(list);
org.json.JSONArray request = new org.json.JSONArray(listNode.toString());
jsonObject.put("list", request);

Seems someone have done it by patching the kernel. I just came across a paper titled "Exploiting Smart-Phone USB Connectivity For Fun And Profit" by Angelos Stavrou, Zhaohui Wang, Computer Science Department George Mason University, Fairfax, VA. (available freely by googling the above title). Here the two researchers are investigating the possibility of a compromised android device controlling the attached PC by having the android device presenting itself as an HID device (keyboard). As a proof of concept, it seems that they have successfully patched a kernel doing exactly what you want. They didn't provide detailed steps but anyway I just quote what they said they've done:

.....we developed a special USB gadget driver in addition to existing USB composite interface on the Android Linux kernel using the USB Gadget API for Linux[4]. The UGAL framework helped us implement a simple USB Human Interface Driver (HID) functionality (i.e. device driver) and the glue code between the various kernel APIs. Using the code provided in: “drivers/usb/gadget/composite.c”, we created our own gadget driver as an additional composite USB interface. This driver simulates a USB keyboard device. We can also simulate a USB mouse device sending pre-programmed input command to the desktop system. Therefore, it is straightforward to pose as a normal USB mouse or keyboard device and send predefined command stealthily to simulate malicious interactive user activities. To verify this functionality, in our controlled experiments, we send keycode sequences to perform non-fatal operations and show how such a manipulated device can cause damages In particular, we simulated a Dell USB keyboard (vendorID=413C, productID=2105) sending ”CTRL+ESC” key combination and ”U” and ”Enter” key sequence to reboot the machine. Notice that this only requires USB connection and can gain the ”current user” privilege on the desktop system. With the additional local or remote exploit sent as payload, the malware can escalate the privilege and gain full access of the desktop system.

Well there's always

assertThat(list.isEmpty(), is(false));

... but I'm guessing that's not quite what you meant :)

Alternatively:

assertThat((Collection)list, is(not(empty())));

empty() is a static in the Matchers class. Note the need to cast the list to Collection, thanks to Hamcrest 1.2's wonky generics.

Following from Ryan's answer, I think that the interface you are looking for is defined as follows:

interface Param {
    title: string;
    callback: () => void;
}

XDocument xdoc = XDocument.Load(path_to_xml);
var word = xdoc.Elements("word")
               .SingleOrDefault(w => (string)w.Element("category") == "verb");

This query will return whole word XElement. If there is more than one word element with category verb, than you will get an InvalidOperationException. If there is no elements with category verb, result will be null.

Yes, this is possible. You don't have to be the current process owning the socket to close it. Consider for a moment that the remote machine, the network card, the network cable, and your OS can all cause the socket to close.

Consider also that Fiddler and Desktop VPN software can insert themselves into the network stack and show you all your traffic or reroute all your traffic.

So all you really need is either for Windows to provide an API that allows this directly, or for someone to have written a program that operates somewhat like a VPN or Fiddler and gives you a way to close sockets that pass through it.

There is at least one program (CurrPorts) that does exactly this and I used it today for the purpose of closing specific sockets on a process that was started before CurrPorts was started. To do this you must run it as administrator, of course.

Note that it is probably not easily possible to cause a program to not listen on a port (well, it is possible but that capability is referred to as a firewall...), but I don't think that was being asked here. I believe the question is "how do I selectively close one active connection (socket) to the port my program is listening on?". The wording of the question is a bit off because a port number for the undesired inbound client connection is given and it was referred to as "port" but it's pretty clear that it was a reference to that one socket and not the listening port.

When you have a function in the base class, you can Redefine or Override it in the derived class.

Redefining a method : A new implementation for the method of base class is given in the derived class. Does not facilitate Dynamic binding.

Overriding a method: Redefining a virtual method of the base class in the derived class. Virtual method facilitates Dynamic Binding.

So when you said :

But earlier in the book, when learning about basic inheritance, I was able to override base methods in derived classes without using 'virtual'.

you were not overriding it as the method in the base class was not virtual, rather you were redefining it

The jsonify() function in flask returns a flask.Response() object that already has the appropriate content-type header 'application/json' for use with json responses. Whereas, the json.dumps() method will just return an encoded string, which would require manually adding the MIME type header.

See more about the jsonify() function here for full reference.

Edit: Also, I've noticed that jsonify() handles kwargs or dictionaries, while json.dumps() additionally supports lists and others.

You can resize images using CSS just fine if you're modifying an image tag:

<img src="example.png" style="width:2em; height:3em;" />

You cannot scale a background-image property using CSS2, although you can try the CSS3 property background-size.

What you can do, on the other hand, is to nest an image inside a span. See the answer to this question: Stretch and scale CSS background

Wait and await - while similar conceptually - are actually completely different.

Wait will synchronously block until the task completes. So the current thread is literally blocked waiting for the task to complete. As a general rule, you should use "async all the way down"; that is, don't block on async code. On my blog, I go into the details of how blocking in asynchronous code causes deadlock.

await will asynchronously wait until the task completes. This means the current method is "paused" (its state is captured) and the method returns an incomplete task to its caller. Later, when the await expression completes, the remainder of the method is scheduled as a continuation.

You also mentioned a "cooperative block", by which I assume you mean a task that you're Waiting on may execute on the waiting thread. There are situations where this can happen, but it's an optimization. There are many situations where it can't happen, like if the task is for another scheduler, or if it's already started or if it's a non-code task (such as in your code example: Wait cannot execute the Delay task inline because there's no code for it).

You may find my async / await intro helpful.

It is very simple to adding an image into project and view the image. First create a folder into in your project which can contain any type of images.

Then Right click on Project ->>Go to Build Path ->> configure Build Path ->> add Class folder ->> choose your folder (which you just created for store the images) under the project name.

I am using Tensorflow version 2.3.1 and none of the solutions above have been fully effective.
Until, I find this package.

Install like this:

with Anaconda,

python -m pip install silence-tensorflow

with IDEs,

pip install silence-tensorflow

And add to the first line of code:

from silence_tensorflow import silence_tensorflow
silence_tensorflow()

That's It!

This Perl code edits your original file:

perl -i -ne 's/^\s+//;print' file

The next one makes a backup copy before editing the original file:

perl -i.bak -ne 's/^\s+//;print' file

Notice that Perl borrows heavily from sed (and AWK).

The error was that you cannot use this in the grep, but you must use a reference to the element. This works:

function findPurpose(purposeName){
    return $.grep(purposeObjects, function(n, i){
      return n.purpose == purposeName;
    });
};

findPurpose("daily");

returns:

[Object { purpose="daily"}]

You can use the excellent pandas, which has a built in clipboard support, but you need to pass through a DataFrame.

import pandas as pd
df=pd.DataFrame(['Text to copy'])
df.to_clipboard(index=False,header=False)

According to View documentation

The identifier does not have to be unique in this view's hierarchy. The identifier should be a positive number.

So you can use any positive integer you like, but in this case there can be some views with equivalent id's. If you want to search for some view in hierarchy calling to setTag with some key objects may be handy.

I think doing this way is much simpler:

button.setBackgroundColor(Color.BLACK);

And you need to import android.graphics.Color; not: import android.R.color;

Or you can just write the 4-byte hex code (not 3-byte) 0xFF000000 where the first byte is setting the alpha.

Following up on farktronix's suggestion, we have been using Jira ticket numbers for similar in mercurial, and I'm planning to continue using them for git branches. But I think the ticket number itself is probably unique enough. While it might be helpful to have a descriptive word in the branch name as farktronix noted, if you are switching between branches often enough, you probably want less to type. Then if you need to know the branch name, look in Jira for the associated keywords in the ticket if you don't know it. In addition, you should include the ticket number in each comment.

If your branch represents a version, it appears that the common convention is to use x.x.x (example: "1.0.0") format for branch names and vx.x.x (example "v1.0.0") for tag names (to avoid conflict). See also: is-there-an-standard-naming-convention-for-git-tags

If the element is position absolutely, then it isn't relative, or in reference to any object - including the page itself. So margin: auto; can't decide where the middle is.

Its waiting to be told explicitly, using left and top where to position itself.

You can still center it programatically, using javascript or somesuch.

Just in case...
If you are using SoapUI Mock Service (as the Server), calling it from a C# WCF:

WCF --> SoapUI MockService

And in this case you are getting the same error:

The content type text/html; charset=UTF-8 of the response message does not match the content type of the binding (text/xml; charset=utf-8).

Edit your Mock Response at SoapUI and add a Header to it:

In my scenario, this fix the problem.

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

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

Use the RAISERROR function:

RAISERROR( 'This message will show up right away...',0,1) WITH NOWAIT

You shouldn't completely replace all your prints with raiserror. If you have a loop or large cursor somewhere just do it once or twice per iteration or even just every several iterations.

Also: I first learned about RAISERROR at this link, which I now consider the definitive source on SQL Server Error handling and definitely worth a read:
http://www.sommarskog.se/error-handling-I.html

As previously mentioned - in case of a project, Makefile or otherwise, this is a project configuration issue, where you'll likely need to specify other flags too.

But what about one-off programs, where you would normally just write g++ file.cpp && ./a.out?

Well, I would much like to have some #pragma to turn in on at source level, or maybe a default extension - say .cxx or .C11 or whatever, trigger it by default. But as of today, there is no such feature.

But, as you probably are working in a manual environment (i.e. shell), you can just have an alias in you .bashrc (or whatever):

alias g++11="g++ -std=c++0x"

or, for newer G++ (and when you want to feel "real C++11")

alias g++11="g++ -std=c++11"

You can even alias to g++ itself, if you hate C++03 that much ;)

In your src/main/resources put an application.properties or application.yml and put a server.contextPath in there.

server.contextPath=/your/context/here

When starting your application the application will be available at http://localhost:8080/your/context/here.

For a comprehensive list of properties to set see Appendix A. of the Spring Boot reference guide.

Instead of putting it in the application.properties you can also pass it as a system property when starting your application

java -jar yourapp.jar -Dserver.contextPath=/your/path/here

I am using MEANJS 0.6.0 with [email protected], it's good

Client:

Controller:

var input = { keyword: vm.keyword };
ProductAPi.getOrder(input)

services:

this.getOrder = function (input) {return $http.get('/api/order', { params: input });};

Server

routes

app.route('/api/order').get(products.order);

controller

exports.order = function (req, res) {
  var keyword = req.query.keyword
  ...

I used similar approach, but I wanted to

1. Keep the Dialog code as a widget in a separated file so I can reuse it.
2. Blurr the background when the dialog is shown.

Code: 1. alertDialog_widget.dart

import 'dart:ui';
import 'package:flutter/material.dart';


class BlurryDialog extends StatelessWidget {

  String title;
  String content;
  VoidCallback continueCallBack;

  BlurryDialog(this.title, this.content, this.continueCallBack);
  TextStyle textStyle = TextStyle (color: Colors.black);

  @override
  Widget build(BuildContext context) {
    return BackdropFilter(
      filter: ImageFilter.blur(sigmaX: 6, sigmaY: 6),
      child:  AlertDialog(
      title: new Text(title,style: textStyle,),
      content: new Text(content, style: textStyle,),
      actions: <Widget>[
        new FlatButton(
          child: new Text("Continue"),
           onPressed: () {
            continueCallBack();
          },
        ),
        new FlatButton(
          child: Text("Cancel"),
          onPressed: () {
            Navigator.of(context).pop();
          },
        ),
      ],
      ));
  }
}

You can call this in main (or wherever you want) by creating a new method like:

 _showDialog(BuildContext context)
{

  VoidCallback continueCallBack = () => {
 Navigator.of(context).pop(),
    // code on continue comes here

  };
  BlurryDialog  alert = BlurryDialog("Abort","Are you sure you want to abort this operation?",continueCallBack);


  showDialog(
    context: context,
    builder: (BuildContext context) {
      return alert;
    },
  );
}

subprocess.Popen does exactly what you want.

from subprocess import Popen
p = Popen(['watch', 'ls']) # something long running
# ... do other stuff while subprocess is running
p.terminate()

(Edit to complete the answer from comments)

The Popen instance can do various other things like you can poll() it to see if it is still running, and you can communicate() with it to send it data on stdin, and wait for it to terminate.

request.getRequestDispatcher(“url”) means the dispatch is relative to the current HTTP request.Means this is for chaining two servlets with in the same web application Example

RequestDispatcher reqDispObj = request.getRequestDispatcher("/home.jsp");

getServletContext().getRequestDispatcher(“url”) means the dispatch is relative to the root of the ServletContext.Means this is for chaining two web applications with in the same server/two different servers

Example

RequestDispatcher reqDispObj = getServletContext().getRequestDispatcher("/ContextRoot/home.jsp");

Try this:

Date date=new Date("12/12/11 8:22:09 PM");    
System.out.println("Time in 24Hours ="+new SimpleDateFormat("HH:mm").format(date));

This example let may highlight the differ between "at" and "asterix" while we using them. I declared two arrays "fruits" and "vegetables"

fruits=(apple pear plumm peach melon)            
vegetables=(carrot tomato cucumber potatoe onion)

printf "Fruits:\t%s\n" "${fruits[*]}"            
printf "Fruits:\t%s\n" "${fruits[@]}"            
echo + --------------------------------------------- +      
printf "Vegetables:\t%s\n" "${vegetables[*]}"    
printf "Vegetables:\t%s\n" "${vegetables[@]}"    

See the following result the code above:

Fruits: apple pear plumm peach melon
Fruits: apple
Fruits: pear
Fruits: plumm
Fruits: peach
Fruits: melon
+ --------------------------------------------- +
Vegetables: carrot tomato cucumber potatoe onion
Vegetables: carrot
Vegetables: tomato
Vegetables: cucumber
Vegetables: potatoe
Vegetables: onion

No, it's not the script, it's the fact that your script is not executed by Python at all. If your script is stored in a file named script.py, you have to execute it as python script.py, otherwise the default shell will execute it and it will bail out at the from keyword. (Incidentally, from is the name of a command line utility which prints names of those who have sent mail to the given username, so that's why it tries to access the mailboxes).

Another possibility is to add the following line to the top of the script:

#!/usr/bin/env python

This will instruct your shell to execute the script via python instead of trying to interpret it on its own.

$("input[name='bla[]']").each( function () {
    alert($(this).val());
});

Not sure what your asking!

However

SELECT  GETDATE()

Will get you the current date and time

SELECT  DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))

Will get you just the date with time set to 00:00:00

The following example shows how to use the range operator in a for loop to implement a foreach loop.

func PrintXml (out io.Writer, value interface{}) error {
    var data []byte
    var err error

    for _, action := range []func() {
        func () { data, err = xml.MarshalIndent(value, "", "  ") },
        func () { _, err = out.Write([]byte(xml.Header)) },
        func () { _, err = out.Write(data) },
        func () { _, err = out.Write([]byte("\n")) }} {
        action();
        if err != nil {
            return err
        }
    }
    return nil;
}

The example iterates over an array of functions to unify the error handling for the functions. A complete example is at Google´s playground.

PS: it shows also that hanging braces are a bad idea for the readability of code. Hint: the for condition ends just before the action() call. Obvious, isn't it?

or try

trigger_error('Die', E_ERROR);

A Magento Module is a group of directories containing blocks, controllers, helpers, and models that are needed to create a specific store feature. It is the unit of customization in the Magento platform. Magento Modules can be created to perform multiple functions with supporting logic to influence user experience and storefront appearance. It has a life cycle that allows them to be installed, deleted, or disabled. From the perspective of both merchants and extension developers, modules are the central unit of the Magento platform.

Declaration of Module

We have to declare the module by using the configuration file. As Magento 2 search for configuration module in etc directory of the module. So now we will create configuration file module.xml.

The code will look like this:

<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd"> <module name="Cloudways_Mymodule" setup_version="1.0.0"></module> </config>

Registration of Module The module must be registered in the Magento 2 system by using Magento Component Registrar class. Now we will create the file registration.php in the module root directory:

app/code/Cloudways/Mymodule/registration.php

The Code will look like this:

?php
\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Cloudways_Mymodule',
__DIR__
);

Check Module Status After following the steps above, we would have created a simple module. Now we are going to check the status of the module and whether it is enabled or disabled by using the following command line:

php bin/magento module:status

php bin/magento module:enable Cloudways_Mymodule

Share your feedback once you have gone through complete process

If your page is refreshed on submitting - yes, but only through the querystring: http://www.bloggingdeveloper.com/post/JavaScript-QueryString-ParseGet-QueryString-with-Client-Side-JavaScript.aspx (You must use method "GET" then). Else, you can return its value from the php script.

Built upon rsplak's answer. It uses jQuery's newer .on() instead of the deprecated .bind(). In addition to input, it will also work for select and other html elements. It will also disable the submit button if one of the fields becomes blank again.

var fields = "#user_input, #pass_input, #v_pass_input, #email";

$(fields).on('change', function() {
    if (allFilled()) {
        $('#register').removeAttr('disabled');
    } else {
        $('#register').attr('disabled', 'disabled');
    }
});

function allFilled() {
    var filled = true;
    $(fields).each(function() {
        if ($(this).val() == '') {
            filled = false;
        }
    });
    return filled;
}

Demo: JSFiddle

The other answers given here work well since you use the same renderer in every column.

However, I tend to believe that generally when using a JTable you will have different types of data in each columm and therefore you won't be using the same renderer for each column. In these cases you may find the Table Row Rendering approach helpfull.

You either need to increase the max_connections configuration setting or (probably better) use connection pooling to route a large number of user requests through a smaller connection pool.

Study up on multidimensional arrays. This question might help.

import itertools

foos=[1.0, 2.0, 3.0, 4.0, 5.0]
bars=[1, 2, 3]

print zip(foos, itertools.cycle([bars]))

Just an update on more current OS's (Vista, Win7, etc.) - the temp file path has changed may be different based on several variables. The items below are not definitive, however, they are a few I have encountered:

"temp" environment variable setting - then it would be:

%temp%\Temporary ASP.NET Files

Permissions and what application/process (VS, IIS, IIS Express) is running the .Net compiler. Accessing the C:\WINDOWS\Microsoft.NET\Framework folders requires elevated permissions and if you are not developing under an account with sufficient permissions then this folder might be used:

c:\Users\[youruserid]\AppData\Local\Temp\Temporary ASP.NET Files

There are also cases where the temp folder can be set via config for a machine or site specific using this:

<compilation tempDirectory="d:\MyTempPlace" />

I even have a funky setup at work where we don't run Admin by default, plus the IT guys have login scripts that set %temp% and I get temp files in 3 different locations depending on what is compiling things! And I'm still not certain about how these paths get picked....sigh.

Still, dthrasher is correct, you can just delete these and VS and IIS will just recompile them as needed.

import time  
current = time.time()

...job...
end = time.time()
diff = end - current

would that work for you?

Use content="IE=edge,chrome=1"   Skip other X-UA-Compatible modes

<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
                                   -------------------------- 

• No compatibility icon
  The IE9 Address bar does not show up the Compatibility View button
  and the page does not also show up a jumble of out-of-place menus, images, and text boxes.

• Features
  This meta tag is required to enable javascript::JSON.parse() on IE8
  (even when <!DOCTYPE html> is present)

• Correctness
  Rendering/Execution of modern HTML/CSS/JavaScript is more valid (nicer).

• Performance
  The Trident rendering engine should run faster in its edge mode.

Usage

In your HTML

<!DOCTYPE html> 
<html> 
  <head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

• IE=edge means IE should use the latest (edge) version of its rendering engine
• chrome=1 means IE should use the Chrome rendering engine if installed

Or better in the configuration of your web server:
(see also the RiaD's answer)

• Apache as proposed by pixeline

  <IfModule mod_setenvif.c>
    <IfModule mod_headers.c>
      BrowserMatch MSIE ie
      Header set X-UA-Compatible "IE=Edge,chrome=1" env=ie
    </IfModule>
  </IfModule>
  <IfModule mod_headers.c>
    Header append Vary User-Agent
  </IfModule>
  

• Nginx as proposed by Stef Pause

  server {
    #...
    add_header X-UA-Compatible "IE=Edge,chrome=1";
  }
  

• Varnish proxy as proposed by Lucas Riutzel

  sub vcl_deliver {
    if( resp.http.Content-Type ~ "text/html" ) {
      set resp.http.X-UA-Compatible = "IE=edge,chrome=1";
    }
  }
  

• IIS (since v7)

  <configuration>
    <system.webServer>
       <httpProtocol>
          <customHeaders>
             <add name="X-UA-Compatible" value="IE=edge,chrome=1" />

       </httpProtocol>
    </system.webServer>
  </configuration>
  

Microsoft recommends Edge mode since IE11

As noticed by Lynda (see comments), the Compatibility changes in IE11 recommends Edge mode:

Starting with IE11, edge mode is the preferred document mode; it represents the highest support for modern standards available to the browser.

But the position of Microsoft was not clear. Another MSDN page did not recommend Edge mode:

Because Edge mode forces all pages to be opened in standards mode, regardless of the version of Internet Explorer, you might be tempted to use this for all pages viewed with Internet Explorer. Don't do this, as the X-UA-Compatible header is only supported starting with Windows Internet Explorer 8.

Instead, Microsoft recommended using <!DOCTYPE html>:

If you want all supported versions of Internet Explorer to open your pages in standards mode, use the HTML5 document type declaration [...]

As Ricardo explains (in the comments below) any DOCTYPE (HTML4, XHTML1...) can be used to trigger Standards Mode, not only HTML5's DOCTYPE. The important thing is to always have a DOCTYPE in the page.

Clara Onager has even noticed in an older version of Specifying legacy document modes:

Edge mode is intended for testing purposes only; do not use it in a production environment.

It is so confusing that Usman Y thought Clara Onager was speaking about:

The [...] example is provided for illustrative purposes only; don't use it in a production environment.

<meta http-equiv="X-UA-Compatible" content="IE=7,9,10" >

Well... In the rest of this answer I give more explanations why using content="IE=edge,chrome=1" is a good practice in production.

History

For many years (2000 to 2008), IE market share was more than 80%. And IE v6 was considered as a de facto standard (80% to 97% market share in 2003, 2004, 2005 and 2006 for IE6 only, more market share with all IE versions).

As IE6 was not respecting Web standards, developers had to test their website using IE6. That situation was great for Microsoft (MS) as web developers had to buy MS products (e.g. IE cannot be used without buying Windows), and it was more profit-making to stay non-compliant (i.e. Microsoft wanted to become the standard excluding other companies).

Therefore many many sites were IE6 compliant only, and as IE was not compliant with web standard, all these web sites was not well rendered on standards compliant browsers. Even worse, many sites required only IE.

However, at this time, Mozilla started Firefox development respecting as much as possible all the web standards (other browser were implemented to render pages as done by IE6). As more and more web developers wanted to use the new web standards features, more and more websites were more supported by Firefox than IE.

When IE market sharing was decreasing, MS realized staying standard incompatible was not a good idea. Therefore MS started to release new IE version (IE8/IE9/IE10) respecting more and more the web standards.

The web-incompatible issue

But the issue is all the websites designed for IE6: Microsoft could not release new IE versions incompatible with these old IE6-designed websites. Instead of deducing the IE version a website has been designed, MS requested developers to add extra data (X-UA-Compatible) in their pages.

IE6 is still used in 2016

Nowadays, IE6 is still used (0.7% in 2016) (4.5% in January 2014), and some internet websites are still IE6-only-compliant. Some intranet website/applications are tested using IE6. Some intranet website are 100% functional only on IE6. These companies/departments prefer to postpone the migration cost: other priorities, nobody no longer knows how the website/application has been implemented, the owner of the legacy website/application went bankrupt...

China represents 50% of IE6 usage in 2013, but it may change in the next years as Chinese Linux distribution is being broadcast.

Be confident with your web skills

If you (try to) respect web standard, you can simply always use http-equiv="X-UA-Compatible" content="IE=edge,chrome=1". To keep compatibility with old browsers, just avoid using latest web features: use the subset supported by the oldest browser you want to support. Or If you want to go further, you may adopt concepts as Graceful degradation, Progressive enhancement and Unobtrusive JavaScript. (You may also be pleased to read What should a web developer consider?.)

Do do not care about the best IE version rendering: this is not your job as browsers have to be compliant with web standards. If your site is standard compliant and use moderately latest features, therefore browsers have to be compliant with your website.

Moreover, as there are many campaigns to kill IE6 (IE6 no more, MS campaign), nowadays you may avoid wasting time with IE testing!

Personal IE6 experience

In 2009-2012, I worked for a company using IE6 as the official single browser allowed. I had to implement an intranet website for IE6 only. I decided to respect web standard but using the IE6-capable subset (HTML/CSS/JS).

It was hard, but when the company switched to IE8, the website was still well rendered because I had used Firefox and firebug to check the web-standard compatibility ;)

There are several options.

The easiest is likely the exec plugin.

You can also generate a jar containing all the dependencies using the assembly plugin.

Lastly, you can generate a file with the classpath in it using the dependency:classpath goal.

It seems like you want

wait $PID

which will return when $pid finishes.

Otherwise you can use

ps -p $PID

to check if the process is still alive (this is more effective than kill -0 $pid because it will work even if you don't own the pid).

just to extend @GabLeRoux's answer:

this way you will be able to adjust the size of the thumbnail image in the README.md file on you Github repo.

The following example shows how to test the value of the IsPostBack property when the page is loaded in order to determine whether the page is being rendered for the first time or is responding to a postback. If the page is being rendered for the first time, the code calls the Page.Validate method. The page markup (not shown) contains RequiredFieldValidator controls that display asterisks if no entry is made for a required input field. Calling Page.Validate causes the asterisks to be displayed immediately when the page is rendered, instead of waiting until the user clicks the Submit button. After a postback, you do not have to call Page.Validate, because that method is called as part of the Page life cycle.

 private void Page_Load()
    {
        if (!IsPostBack)
        {      
        }
    }

First check if the request object have the 'is_private' key parameter. Most of the case's this MultiValueDictKeyError occurred for missing key in the dictionary-like request object. Because dictionary is an unordered key, value pair “associative memories” or “associative arrays”

In another word. request.GET or request.POST is a dictionary-like object containing all request parameters. This is specific to Django.

The method get() returns a value for the given key if key is in the dictionary. If key is not available then returns default value None.

You can handle this error by putting :

is_private = request.POST.get('is_private', False);

Also, if you have two subsequent words in regular text and you want to avoid a line break between them, you can use the ~ character.

For example:

As we can see in Fig.~\ref{BlaBla}, there is nothing interesting to see. A~better place..

This can ensure that you don't have a line starting with a figure number (without the Fig. part) or with an uppercase A.

I was getting this error after deploying on IIS Server PC.

1. First Install Microsoft SQL Server 2014 Feature Pack

https://www.microsoft.com/en-us/download/details.aspx?id=42295enter link description here

2. Install Microsoft Report Viewer 2015 Runtime redistributable package

It may require restart your computer.

I had this problem trying save a dictionary to NSUserDefaults. It turns out it wouldn't save because it contained NSNull values. So I just copied the dictionary into a mutable dictionary removed the nulls then saved to NSUserDefaults

NSMutableDictionary* dictionary = [NSMutableDictionary dictionaryWithDictionary:dictionary_trying_to_save];
[dictionary removeObjectForKey:@"NullKey"];
[[NSUserDefaults standardUserDefaults] setObject:dictionary forKey:@"key"];

In this case I knew which keys might be NSNull values.

In http nginx section (/etc/nginx/nginx.conf) add or modify:

keepalive_timeout 300s

In server nginx section (/etc/nginx/sites-available/your-config-file.com) add these lines:

client_max_body_size 50M;
fastcgi_buffers 8 1600k;
fastcgi_buffer_size 3200k;
fastcgi_connect_timeout 300s;
fastcgi_send_timeout 300s;
fastcgi_read_timeout 300s;

In php file in the case 127.0.0.1:9000 (/etc/php/7.X/fpm/pool.d/www.conf) modify:

request_terminate_timeout = 300

I hope help you.

When you create a folder with N entries, you create a list of N items at file-system level. This list is a system-wide shared data structure. If you then start modifying this list continuously by adding/removing entries, I expect at least some lock contention over shared data. This contention - theoretically - can negatively affect performance.

For read-only scenarios I can't imagine any reason for performance degradation of directories with large number of entries.

I've experienced similar problem. Although I had have UTF-8 encodings solved (with mysql2 and Encoding.default_external = Encoding::UTF_8 ...) incompatible character encodings: UTF-8 and ASCII-8BIT arose when I used incorrect helper parameters e.g. f.button :submit, "Zrušit" - works perfectly but f.button "Zrušit"- throws encoding error.

The first answer is too complex, historic, and uninformative for my tastes.

It's actually rather simple. Docker provides for a functionality called multi-stage builds the basic idea here is to,

• Free you from having to manually remove what you don't want, by forcing you to whitelist what you do want,
• Free resources that would otherwise be taken up because of Docker's implementation.

Let's start with the first. Very often with something like Debian you'll see.

RUN apt-get update \ 
  && apt-get dist-upgrade \
  && apt-get install <whatever> \
  && apt-get clean

We can explain all of this in terms of the above. The above command is chained together so it represents a single change with no intermediate Images required. If it was written like this,

RUN apt-get update ;
RUN apt-get dist-upgrade;
RUN apt-get install <whatever>;
RUN apt-get clean;

It would result in 3 more temporary intermediate Images. Having it reduced to one image, there is one remaining problem: apt-get clean doesn't clean up artifacts used in the install. If a Debian maintainer includes in his install a script that modifies the system that modification will also be present in the final solution (see something like pepperflashplugin-nonfree for an example of that).

By using a multi-stage build you get all the benefits of a single changed action, but it will require you to manually whitelist and copy over files that were introduced in the temporary image using the COPY --from syntax documented here. Moreover, it's a great solution where there is no alternative (like an apt-get clean), and you would otherwise have lots of un-needed files in your final image.

There are two steps you can take:

1. Go to configurations and enter the name of activity to be launched
2. If it is still not working Disable Instant Run

Assuming that ID is an identity column:

INSERT INTO TheTable(HospitalID, Email, Description)
SELECT 32, Email, Description FROM TheTable
WHERE HospitalID <> 32

Try to avoid loops with SQL. Try to think in terms of sets instead.

If you are looking for Simple/quicker way, you can follow this solution.

1. Right click on your project.
2. Goto > Build Path > Configure Build Path > Java Build Path
3. Goto 'Source' tab, there, you can see like <<your_project_name>>/src/main/java(missing).
4. Click on it and remove.
5. Click on Apply and Close.
6. Now, right click on project and >New > Source folder > add source folder "src/main/java".

happy learning and do not forget to upvote :)

STEP 1: FIRST OPEN THE COMMAND PROMPT WHERE YOUR FILE IS LOCATED. (right click while pressing shift)
STEP 2: THEN USE THE FOLLOWING COMMANDS TO EXECUTE. (lets say the file and class name to be executed is named as Student.java)The example program is in the picture background.

     javac Student.java
     java Student

I would explain that way:

OneToOne - OneToOne relationship

@OneToOne
Person person;

@OneToOne
Nose nose;

OneToMany - ManyToOne relationship

@OneToMany
Shepherd> shepherd;

@ManyToOne
List<Sheep> sheeps;

ManyToMany - ManyToMany relationship

@ManyToMany
List<Traveler> travelers;

@ManyToMany
List<Destination> destinations;

Here is the best method that I've found: First, set your projects output type to "Windows Application", then P/Invoke AllocConsole to create a console window.

internal static class NativeMethods
{
    [DllImport("kernel32.dll")]
    internal static extern Boolean AllocConsole();
}

static class Program
{

    static void Main(string[] args) {
        if (args.Length == 0) {
            // run as windows app
            Application.EnableVisualStyles();
            Application.Run(new Form1()); 
        } else {
            // run as console app
            NativeMethods.AllocConsole();
            Console.WriteLine("Hello World");
            Console.ReadLine();
        }
    }

}

Oh, but that's ugly, non-object-oriented code. The moment you see "if/else" and "typeof", you should be thinking polymorphism. This is the wrong way to go. I think generics are your friend here.

How many types do you plan to deal with?

UPDATE:

If you're just talking about String and int, here's one way you might do it. Start with the interface XmlGenerator (enough with "foo"):

package generics;

public interface XmlGenerator<T>
{
   String getXml(T value);
}

And the concrete implementation XmlGeneratorImpl:

    package generics;

public class XmlGeneratorImpl<T> implements XmlGenerator<T>
{
    private Class<T> valueType;
    private static final int DEFAULT_CAPACITY = 1024;

    public static void main(String [] args)
    {
        Integer x = 42;
        String y = "foobar";

        XmlGenerator<Integer> intXmlGenerator = new XmlGeneratorImpl<Integer>(Integer.class);
        XmlGenerator<String> stringXmlGenerator = new XmlGeneratorImpl<String>(String.class);

        System.out.println("integer: " + intXmlGenerator.getXml(x));
        System.out.println("string : " + stringXmlGenerator.getXml(y));
    }

    public XmlGeneratorImpl(Class<T> clazz)
    {
        this.valueType = clazz;
    }

    public String getXml(T value)
    {
        StringBuilder builder = new StringBuilder(DEFAULT_CAPACITY);

        appendTag(builder);
        builder.append(value);
        appendTag(builder, false);

        return builder.toString();
    }

    private void appendTag(StringBuilder builder) { this.appendTag(builder, false); }

    private void appendTag(StringBuilder builder, boolean isClosing)
    {
        String valueTypeName = valueType.getName();
        builder.append("<").append(valueTypeName);
        if (isClosing)
        {
            builder.append("/");
        }
        builder.append(">");
    }
}

If I run this, I get the following result:

integer: <java.lang.Integer>42<java.lang.Integer>
string : <java.lang.String>foobar<java.lang.String>

I don't know if this is what you had in mind.

UPDATE `table` SET table_column='test';

Quite a few answers here recommend adding the slf4j-simple dependency to your maven pom file. You might want to check for the most current version.

At https://mvnrepository.com/artifact/org.slf4j/slf4j-simple you'll find the latest version of the SLF4J Simple Binding. Pick the one that suites you best (still 1.7.30 from 2019-12 is the stable version as of 2020-10) and include it to your pom.xml.

For your convenience some dependencies are shown here - but they might not be up-to-date when you read this!

Alpha Version of 2019-10

<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-simple -->

I removed the scope test part thanks to the comment below.

if multiple (x) rows in Dim_Member are associated with a single row in Susp_Visits, there will be x rows in the resul set.

You didn't say which database server you are using, but if temp tables are available they may be the best approach.

// table is a temp table
select ... into #table ....
SELECT COUNT(column1),column1 FROM #table GROUP BY column1  
SELECT COUNT(column2),column2 FROM #table GROUP BY column2  
SELECT COUNT(column3),column3 FROM #table GROUP BY column3  
// drop may not be required
drop table #table

The following code does what is required

function doTest() {
  SpreadsheetApp.getActiveSheet().getRange('F2').setValue('Hello');
}

For completeness I'll add http://code.google.com/p/jlibs/wiki/XSInstance, which was mentioned in a similar (but Java-specific) question: Any Java "API" to generate Sample XML from XSD?

I just try adb kill-server, it works for me:

PS C:\Users\languoguang> adb devices
List of devices attached
MKJ0117A19000186        unauthorized
PS C:\Users\languoguang> adb shell
error: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.

kill and start adb server:

PS C:\Users\languoguang> adb kill-server
PS C:\Users\languoguang> adb start-server
* daemon not running; starting now at tcp:12345
* daemon started successfully
PS C:\Users\languoguang> adb devices
List of devices attached
MKJ0117A19000186        device

when I use the function

select dbo.decode(10>1 ,'yes' ,'no')

then say syntax error near '>'

Unfortunately, that does not get you around having the CASE clause in the SQL, since you would need it to convert the logical expression to a bit parameter to match the type of the first function argument:

create function decode(@var1 as bit, @var2 as nvarchar(100), @var3 as nvarchar(100))
returns nvarchar(100)
begin
return case when @var1 = 1 then @var2 else @var3 end;
end;

select dbo.decode(case when 10 > 1 then 1 else 0 end, 'Yes', 'No');

Steps to manually configure DNS:

1. You can access Network and Sharing center by right clicking on the Network icon on the taskbar.

2. Now choose adapter settings from the side menu.

3. This will give you a list of the available network adapters in the system . From them right click on the adapter you are using to connect to the internet now and choose properties option.

4. In the networking tab choose ‘Internet Protocol Version 4 (TCP/IPv4)’.

5. Now you can see the properties dialogue box showing the properties of IPV4. Here you need to change some properties.

   Select ‘use the following DNS address’ option. Now fill the following fields as given here.

   Preferred DNS server: 208.67.222.222

   Alternate DNS server : 208.67.220.220

   This is an available Open DNS address. You may also use google DNS server addresses.

   After filling these fields. Check the ‘validate settings upon exit’ option. Now click OK.

You have to add this DNS server address in the router configuration also (by referring the router manual for more information).

Refer : for above method & alternative

If none of this works, then open command prompt(Run as Administrator) and run these:

ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew
NETSH winsock reset catalog
NETSH int ipv4 reset reset.log
NETSH int ipv6 reset reset.log
Exit

Hopefully that fixes it, if its still not fixed there is a chance that its a NIC related issue(driver update or h/w).

Also FYI, this has a thread on Microsoft community : Windows 10 - DNS Issue

You could also just do a gradient on the bottom - this was helpful for me because the shadow I wanted was on an element that was already semi-transparent, so I didn't have to worry about any clipping:

&:after {
      content:"";
      width:100%;
      height: 8px;
      position: absolute;
      bottom: -8px;
      left: 0;
      background: linear-gradient(to bottom, rgba(0,0,0,0.65) 0%,rgba(0,0,0,0) 100%);
    }

Just make the "bottom" and "height" properties match and set your rgba values to whatever you want them to be at the top / bottom of the shadow

I use this way, you should put a backslash at the end of the directory name to avoid that place exists in a file without extension with the same name as the directory you specified, never use "C:\VTS" because it can a file exists with the name "VTS" saved in "C:" partition, the correct way is to use "C:\VTS\", check out the backslash after the VTS, so is the right way.

@echo off
@break off
@title Create folder with batch but only if it doesn't already exist - D3F4ULT
@color 0a
@cls

setlocal EnableDelayedExpansion

if not exist "C:\VTS\" (
  mkdir "C:\VTS\"
  if "!errorlevel!" EQU "0" (
    echo Folder created successfully
  ) else (
    echo Error while creating folder
  )
) else (
  echo Folder already exists
)

pause
exit

In case you're already using the transform property for positioning your element (as I currently am), you can also animate the top margin:

.ball {
  animation: bounce 1s infinite alternate;
  -webkit-animation: bounce 1s infinite alternate;
}

@keyframes bounce {
  from {
    margin-top: 0;
  }
  to {
    margin-top: -15px;
  }
}

To answer the original question: yes, you can access the index value of a row in apply(). It is available under the key name and requires that you specify axis=1 (because the lambda processes the columns of a row and not the rows of a column).

Working example (pandas 0.23.4):

>>> import pandas as pd
>>> df = pd.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'])
>>> df.set_index('a', inplace=True)
>>> df
   b  c
a      
1  2  3
4  5  6
>>> df['index_x10'] = df.apply(lambda row: 10*row.name, axis=1)
>>> df
   b  c  index_x10
a                 
1  2  3         10
4  5  6         40

Quickest, easiest laziest way to solve the problem:

1. Right-click on the project icon in Solution Explorer and choose "Properties".
2. Go to the "Application" tab and choose an earlier .NET target framework.
3. Save changes.
4. Go to the "Application" tab and choose the initial .NET target framework.
5. Save changes => problem solved!

I had this error when I had the current build configuration in Visual Studio set to something other than Debug.

regarding the recommended answer's code,

For my bot the recommended answer did not work. This is because I'm using Chrome which is requiring me to use KEYEVENTF_SCANCODE in my dwFlags.

To get his code to work I had to modify these code blocks:

class KEYBDINPUT(ctypes.Structure):
    _fields_ = (("wVk",         wintypes.WORD),
                ("wScan",       wintypes.WORD),
                ("dwFlags",     wintypes.DWORD),
                ("time",        wintypes.DWORD),
                ("dwExtraInfo", wintypes.ULONG_PTR))

    def __init__(self, *args, **kwds):
        super(KEYBDINPUT, self).__init__(*args, **kwds)
        # some programs use the scan code even if KEYEVENTF_SCANCODE
        # isn't set in dwFflags, so attempt to map the correct code.
        #if not self.dwFlags & KEYEVENTF_UNICODE:l
            #self.wScan = user32.MapVirtualKeyExW(self.wVk,
                                                 #MAPVK_VK_TO_VSC, 0)
            # ^MAKE SURE YOU COMMENT/REMOVE THIS CODE^

def PressKey(keyCode):
    input = INPUT(type=INPUT_KEYBOARD,
              ki=KEYBDINPUT(wScan=keyCode,
                            dwFlags=KEYEVENTF_SCANCODE))
    user32.SendInput(1, ctypes.byref(input), ctypes.sizeof(input))

def ReleaseKey(keyCode):
    input = INPUT(type=INPUT_KEYBOARD,
              ki=KEYBDINPUT(wScan=keyCode,
                            dwFlags=KEYEVENTF_SCANCODE | KEYEVENTF_KEYUP))
    user32.SendInput(1, ctypes.byref(input), ctypes.sizeof(input))

time.sleep(5) # sleep to open browser tab
PressKey(0x26) # press right arrow key
time.sleep(2) # hold for 2 seconds
ReleaseKey(0x26) # release right arrow key

I hope this helps someone's headache!

I had similar problem with my Microsoft WebCam. I looked in the image aquisition toolbox in Matlab and found that the maximum supported resolution is 640*480.

I just changed the code in openCV and added

cvSetCaptureProperty(capture, CV_CAP_PROP_FRAME_WIDTH, 352); 
cvSetCaptureProperty(capture, CV_CAP_PROP_FRAME_HEIGHT, 288);

before cvQueryFrame function which was the next supported resolution and changed skipped some initial frames before saving the image and finally got it working.

I am sharing my working Code

#include "cv.h" 
#include "highgui.h" 
#include <stdio.h> 



using namespace cv;
using namespace std;

int main() 
{
CvCapture* capture = cvCaptureFromCAM( CV_CAP_ANY );
cvSetCaptureProperty(capture, CV_CAP_PROP_FRAME_WIDTH, 352); 
cvSetCaptureProperty(capture, CV_CAP_PROP_FRAME_HEIGHT, 288)


 // Get one frame
IplImage* frame;

for (int i = 0; i < 25; i++) 
{
frame = cvQueryFrame( capture );
}


printf( "Image captured \n" );  
//IplImage* RGB_frame = frame;
//cvCvtColor(frame,RGB_frame,CV_YCrCb2BGR);
//cvWaitKey(1000);
cvSaveImage("test.jpg" ,frame);
//cvSaveImage("cam.jpg" ,RGB_frame);

printf( "Image Saved \n" );

//cvWaitKey(10);

// Release the capture device housekeeping
cvReleaseCapture( &capture );
//cvDestroyWindow( "mywindow" );
return 0;
}

My Suggestions:

1. Dont grab frame with maximum resolution
2. Skip some frames for correct camera initialisation

In the following example,

playground is the database name and equipment is the table name

Another way is using SHOW-COLUMNS:5.5 (available also for 5.5>)

$ mysql -uroot -p<password> -h<host> -P<port> -e \
    "SHOW COLUMNS FROM playground.equipment"

And the output:

mysql: [Warning] Using a password on the command line interface can be insecure.

| type  | varchar(50) | YES  |     | NULL    |                |
| quant | int(11)     | YES  |     | NULL    |                |
| color | varchar(25) | YES  |     | NULL    |                |
+-------+-------------+------+-----+---------+----------------+

One can also use mysqlshow-client (also available for 5.5>) like following:

$ mysqlshow -uroot -p<password> -h<host> -P<port> \
    playground equipment

And the output:

mysqlshow: [Warning] Using a password on the command line interface can be insecure.

• Controller will handle the navigation between the different views. Your mappings request mappings are handled with the help of controller.
• Service interacts directly with the repository where usually the business logic is performed. You can add, delete, remove etc at the service layer

$result = mysql_query($query) or die("Data not found."); 
$rows=array(); 
while($r=mysql_fetch_assoc($result))
{ 
$rows[]=$r;
}
header("Content-type:application/json"); 
echo json_encode($rows);

They are not equivalent. The first will execute the block following the if statement if myVar is truthy (i.e. evaluates to true in a conditional), while the second will execute the block if myVar is any value other than null.

The only values that are not truthy in JavaScript are the following (a.k.a. falsy values):

• null
• undefined
• 0
• "" (the empty string)
• false
• NaN

A very portable version (even to legacy bourne shell):

if [ "$varA" = 1 -a \( "$varB" = "t1" -o "$varB" = "t2" \) ]
then    do-something
fi

This has the additional quality of running only one subprocess at most (which is the process [), whatever the shell flavor.

Replace = with -eq if variables contain numeric values, e.g.

• 3 -eq 03 is true, but
• 3 = 03 is false. (string comparison)

Or use sed & regex.

<some_command> | sed 's/^.* \(".*"$\)/\1/'

You can use something like this

("{:0%db}"%length).format(num)

It worked for me:

File file = new File(getApplicationContext().getFilesDir(),"whatever.txt");
    if(file.exists()){
       //Do something
    }
    else{
       //Nothing
     }

Just want to share with what I used so far to save your time.

Here are examples of hard-coded headers and dynamic headers (in case if don't care about data structure). In both cases I wrote some simple directive: customSort

customSort

.directive("customSort", function() {
    return {
        restrict: 'A',
        transclude: true,    
        scope: {
          order: '=',
          sort: '='
        },
        template : 
          ' <a ng-click="sort_by(order)" style="color: #555555;">'+
          '    <span ng-transclude></span>'+
          '    <i ng-class="selectedCls(order)"></i>'+
          '</a>',
        link: function(scope) {

        // change sorting order
        scope.sort_by = function(newSortingOrder) {       
            var sort = scope.sort;

            if (sort.sortingOrder == newSortingOrder){
                sort.reverse = !sort.reverse;
            }                    

            sort.sortingOrder = newSortingOrder;        
        };


        scope.selectedCls = function(column) {
            if(column == scope.sort.sortingOrder){
                return ('icon-chevron-' + ((scope.sort.reverse) ? 'down' : 'up'));
            }
            else{            
                return'icon-sort' 
            } 
        };      
      }// end link
    }
    });

[1st option with static headers]

I used single ng-repeat

This is a good example in Fiddle (Notice, there is no jQuery library!)

           <tbody>
                <tr ng-repeat="item in pagedItems[currentPage] | orderBy:sortingOrder:reverse">
                    <td>{{item.id}}</td>
                    <td>{{item.name}}</td>
                    <td>{{item.description}}</td>
                    <td>{{item.field3}}</td>
                    <td>{{item.field4}}</td>
                    <td>{{item.field5}}</td>
                </tr>
            </tbody>

As a side note:

The ng-bind-html-unsafe is deprecated, so I used it only for Demo (2nd example). You welcome to edit.

On SuSE, there are two different configuration files for PHP: one for Apache, and one for CLI (command line interface). In the /etc/php5/ directory, you will find an "apache2" directory and a "cli" directory. Each has a "php.ini" file. The files are for the same purpose (php configuration), but apply to the two different ways of running PHP. These files, among other things, load the modules PHP uses.

If your OS is similar, then these two files are probably not the same. Your Apache php.ini is probably loading the gearman module, while the cli php.ini isn't. When the module was installed (auto or manual), it probably only updated the Apache php.ini file.

You could simply copy the Apache php.ini file over into the cli directory to make the CLI environment exactly like the Apache environment.

Or, you could find the line that loads the gearman module in the Apache file and copy/paste just it to the CLI file.

It's convenient to define a macro for get current timestamp

class Constant {
    struct Time {
        let now = { round(NSDate().timeIntervalSince1970) } // seconds
    }
} 

Then you can use let timestamp = Constant.Time.now()

This is an example of how to POST multi-part data WITHOUT using external Apache libraries:

byte[] buffer = getBuffer();

if(buffer.length > 0) {
   String lineEnd = "\r\n"; 
   String twoHyphens = "--"; 
   String boundary =  "RQdzAAihJq7Xp1kjraqf"; 

   ByteArrayOutputStream baos = new ByteArrayOutputStream();
   DataOutputStream dos = new DataOutputStream(baos);

   // Send parameter #1
   dos.writeBytes(twoHyphens + boundary + lineEnd); 
   dos.writeBytes("Content-Disposition: form-data; name=\"param1\"" + lineEnd);
   dos.writeBytes("Content-Type: text/plain; charset=US-ASCII" + lineEnd);
   dos.writeBytes("Content-Transfer-Encoding: 8bit" + lineEnd);
   dos.writeBytes(lineEnd);
   dos.writeBytes(myStringData + lineEnd);

   // Send parameter #2
   //dos.writeBytes(twoHyphens + boundary + lineEnd); 
   //dos.writeBytes("Content-Disposition: form-data; name=\"param2\"" + lineEnd + lineEnd);
   //dos.writeBytes("foo2" + lineEnd);

   // Send a binary file
   dos.writeBytes(twoHyphens + boundary + lineEnd); 
   dos.writeBytes("Content-Disposition: form-data; name=\"param3\";filename=\"test_file.dat\"" + lineEnd); 
   dos.writeBytes("Content-Type: application/octet-stream" + lineEnd);
   dos.writeBytes("Content-Transfer-Encoding: binary" + lineEnd);
   dos.writeBytes(lineEnd); 
   dos.write(buffer);
   dos.writeBytes(lineEnd); 
   dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 
   dos.flush(); 
   dos.close();

   ByteArrayInputStream content = new ByteArrayInputStream(baos.toByteArray());
   BasicHttpEntity entity = new BasicHttpEntity();
   entity.setContent(content);

   HttpPost httpPost = new HttpPost(myURL);
   httpPost.addHeader("Connection", "Keep-Alive");
   httpPost.addHeader("Content-Type", "multipart/form-data; boundary="+boundary);

   //MultipartEntity entity = new MultipartEntity();
   //entity.addPart("param3", new ByteArrayBody(buffer, "test_file.dat"));
   //entity.addPart("param1", new StringBody(myStringData));

   httpPost.setEntity(entity);

   /*
   String httpData = "";
   ByteArrayOutputStream baos1 = new ByteArrayOutputStream();
   entity.writeTo(baos1);
   httpData = baos1.toString("UTF-8");
   */

   /*
   Header[] hdrs = httpPost.getAllHeaders();
   for(Header hdr: hdrs) {
     httpData += hdr.getName() + " | " + hdr.getValue() + " |_| ";
   }
   */

   //Log.e(TAG, "httpPost data: " + httpData);
   response = httpClient.execute(httpPost);
}

I realized that I was iterating over a list of lists where some of them were empty. I fixed this by adding this preprocessing step:

tfidfLsNew = [x for x in tfidfLs if x != []]

the len() of the original was 3105, and the len() of the latter was 3101, implying that four of my lists were completely empty. After this preprocess my max() min() etc. were functioning again.

read help GOTO

and try

:again
do it
goto again

Try this:

$(".ct option[value='X']").each(function() {
    $(this).remove();
});

Or to be more terse, this will work just as well:

$(".ct option[value='X']").remove();

Generally it happens, because some browsers settings or plug-ins directly open PDF in the same window like a simple web page.

The following might help you. I have done it in PHP a few years back. But currently I'm not working on that platform.

<?php
    if (isset($_GET['file'])) {
        $file = $_GET['file'];
        if (file_exists($file) && is_readable($file) && preg_match('/\.pdf$/',$file)) {
            header('Content-type: application/pdf');
            header("Content-Disposition: attachment; filename=\"$file\"");
            readfile($file);
        }
    }
    else {
        header("HTTP/1.0 404 Not Found");
        echo "<h1>Error 404: File Not Found: <br /><em>$file</em></h1>";
    }

Save the above as download.php.

Save this little snippet as a PHP file somewhere on your server and you can use it to make a file download in the browser, rather than display directly. If you want to serve files other than PDF, remove or edit line 5.

You can use it like so:

Add the following link to your HTML file.

<a href="download.php?file=my_pdf_file.pdf">Download the cool PDF.</a>

The other answers didn't work for me. I found the answer in their documentation:

http://api.highcharts.com/highcharts#Series

Using this method (see JSFiddle example):

var chart = new Highcharts.Chart({
    chart: {
        renderTo: 'container'
    },

    series: [{
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]        
    }]
});

// the button action
$('#button').click(function() {
    chart.series[0].setData([129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4, 29.9, 71.5, 106.4] );
});

The error message is correct (if not very helpful): the file we're trying to load is not a file on the filesystem, but a chunk of bytes in a ZIP inside a ZIP.

Through experimentation (Java 11, Spring Boot 2.3.x), I found this to work without changing any config or even a wildcard:

var resource = ResourceUtils.getURL("classpath:some/resource/in/a/dependency");
new BufferedReader(
  new InputStreamReader(resource.openStream())
).lines().forEach(System.out::println);

Try cloning, then removing and re-adding the element when the modal is hidden. This should keep all events, though I haven't thoroughly tested this with all versions of everything.

var originalModal = $('#myModal').clone();
$(document).on('#myModal', 'hidden.bs.modal', function () {
    $('#myModal').remove();
    var myClone = originalModal.clone();
    $('body').append(myClone);
});

Not using nmap... but this is an alternative...

arp -n|grep -i B0:D3:93|awk '{print $1}'

Because char is by default signed declared that means the range of the variable is

-127 to +127>

your value is overflowed. To get the desired value you have to declared the unsigned modifier. the modifier's (unsigned) range is:

 0 to 255

to get the the range of any data type follow the process 2^bit example charis 8 bit length to get its range just 2 ^(power) 8.

To remove message on logcat, i add a subtitle to track. On windows, right click on track -> Property -> Details -> insert a text on subtitle. Done :)

@IanDevlin is correct. MDN's rules say the following:

"The HTML Header Element "" defines a page header — typically containing the logo and name of the site and possibly a horizontal menu..."

The word "possibly" there is key. It goes on to say that the header doesn't necessarily need to be a site header. For instance you could include a "header" on a pop-up modal or on other modular parts of the document where there is a header and it would be helpful for a user on a screen reader to know about it.

It terms of the implicit use of NAV you can use it anywhere there is grouped site navigation, although it's usually omitted from the "footer" section for mini-navs / important site links.

Really it comes down to personal / team choice. Decide what you and your team feel is more semantic and more important and the try to be consistent. For me, if the nav is inline with the logo and the main site's "h1" then it makes sense to put it in the "header" but if you have a different design choice then decide on a case by case basis.

Most importantly check out the docs and be sure if you choose to omit or include you understand why you are making that particular decision.

When the directory is deleted, the inode for that directory (and the inodes for its contents) are recycled. The pointer your shell has to that directory's inode (and its contents's inodes) are now no longer valid. When the directory is restored from backup, the old inodes are not (necessarily) reused; the directory and its contents are stored on random inodes. The only thing that stays the same is that the parent directory reuses the same name for the restored directory (because you told it to).

Now if you attempt to access the contents of the directory that your original shell is still pointing to, it communicates that request to the file system as a request for the original inode, which has since been recycled (and may even be in use for something entirely different now). So you get a stale file handle message because you asked for some nonexistent data.

When you perform a cd operation, the shell reevaluates the inode location of whatever destination you give it. Now that your shell knows the new inode for the directory (and the new inodes for its contents), future requests for its contents will be valid.

You need to do

Update table_xpto
set column_xpto = x.xpto_New
    ,column2 = x.column2New
from table_xpto xpto
   inner join table_xptoNew xptoNew ON xpto.bla = xptoNew.Bla
where <clause where>

Definitions:

• delegate: defines a function pointer.
• event: defines
  • (1) protected interfaces, and
  • (2) operations(+=, -=), and
  • (3) advantage: you don't need to use new keyword anymore.

Regarding the adjective protected:

// eventTest.SomeoneSay = null;              // Compile Error.
// eventTest.SomeoneSay = new Say(SayHello); // Compile Error.

Also notice this section from Microsoft: https://docs.microsoft.com/en-us/dotnet/standard/events/#raising-multiple-events

Code Example:

with delegate:

public class DelegateTest
{
    public delegate void Say(); // Define a pointer type "void <- ()" named "Say".
    private Say say;

    public DelegateTest() {
        say  = new Say(SayHello);     // Setup the field, Say say, first.
        say += new Say(SayGoodBye);
        
        say.Invoke();
    }
    
    public void SayHello() { /* display "Hello World!" to your GUI. */ }
    public void SayGoodBye() { /* display "Good bye!" to your GUI. */ }
}

with event:

public class EventTest
{
    public delegate void Say();
    public event Say SomeoneSay;  // Use the type "Say" to define event, an 
                                  // auto-setup-everything-good field for you.
    public EventTest() {
         SomeoneSay += SayHello;
         SomeoneSay += SayGoodBye;

         SomeoneSay();
    }
    
    public void SayHello() { /* display "Hello World!" to your GUI. */ }
    public void SayGoodBye() { /* display "Good bye!" to your GUI. */ }
}

If upper and lower bound of Int32 matters:

public bool IsInt32(double value)
{
    return  value >= int.MinValue && value <= int.MaxValue && value == (int)value;
}

There are two ways to split strings over multiple lines:

Using \

All lines in C can be split into multiple lines using \.

Plain C:

char *my_string = "Line 1 \
                   Line 2";

Objective-C:

NSString *my_string = @"Line1 \
                        Line2";

Better approach

There's a better approach that works just for strings.

Plain C:

char *my_string = "Line 1 "
                  "Line 2";

Objective-C:

NSString *my_string = @"Line1 "
                       "Line2";    // the second @ is optional

The second approach is better, because there isn't a lot of whitespace included. For a SQL query however, both are possible.

NOTE: With a #define, you have to add an extra '\' to concatenate the two strings:

Plain C:

#define kMyString "Line 1"\
                  "Line 2"

the best you export it as sql file and open it with editor such as visual studio code and find and repalace your words. i replace in 1 gig file sql in 1 minutes for 16 word that total is 14600 word. its the best way. and after replace it save and import it again. do not forget compress it with zip for import.

So, it turns out that X11 wasn't actually installed on the centOS. There didn't seem to be any indication anywhere of it not being installed. I did the following command and now firefox opens:

yum groupinstall 'X Window System' 

Hope this answer will help others that are confused :)

Since you asked for a C++ solution...

#include <algorithm>
#include <iterator>

const int arr_size = 10;
some_type src[arr_size];
// ...
some_type dest[arr_size];
std::copy(std::begin(src), std::end(src), std::begin(dest));

You need to restart mongo to solve the topology error, then just change some options of mongoose or mongoclient to overcome this problem:

var mongoOptions = {
    useMongoClient: true,
    keepAlive: 1,
    connectTimeoutMS: 30000,
    reconnectTries: Number.MAX_VALUE,
    reconnectInterval: 5000,
    useNewUrlParser: true
}

mongoose.connect(mongoDevString,mongoOptions);

You are using a wrong overload of the Html.ActionLink helper. What you think is routeValues is actually htmlAttributes! Just look at the generated HTML, you will see that this anchor's href property doesn't look as you expect it to look.

Here's what you are using:

@Html.ActionLink(
    "Reply",                                                  // linkText
    "BlogReplyCommentAdd",                                    // actionName
    "Blog",                                                   // routeValues
    new {                                                     // htmlAttributes
        blogPostId = blogPostId, 
        replyblogPostmodel = Model, 
        captchaValid = Model.AddNewComment.DisplayCaptcha 
    }
)

and here's what you should use:

@Html.ActionLink(
    "Reply",                                                  // linkText
    "BlogReplyCommentAdd",                                    // actionName
    "Blog",                                                   // controllerName
    new {                                                     // routeValues
        blogPostId = blogPostId, 
        replyblogPostmodel = Model, 
        captchaValid = Model.AddNewComment.DisplayCaptcha 
    },
    null                                                      // htmlAttributes
)

Also there's another very serious issue with your code. The following routeValue:

replyblogPostmodel = Model

You cannot possibly pass complex objects like this in an ActionLink. So get rid of it and also remove the BlogPostModel parameter from your controller action. You should use the blogPostId parameter to retrieve the model from wherever this model is persisted, or if you prefer from wherever you retrieved the model in the GET action:

public ActionResult BlogReplyCommentAdd(int blogPostId, bool captchaValid)
{
    BlogPostModel model = repository.Get(blogPostId);
    ...
}

As far as your initial problem is concerned with the wrong overload I would recommend you writing your helpers using named parameters:

@Html.ActionLink(
    linkText: "Reply",
    actionName: "BlogReplyCommentAdd",
    controllerName: "Blog",
    routeValues: new {
        blogPostId = blogPostId, 
        captchaValid = Model.AddNewComment.DisplayCaptcha
    },
    htmlAttributes: null
)

Now not only that your code is more readable but you will never have confusion between the gazillions of overloads that Microsoft made for those helpers.

A simple solution is to assign color for each class. This way, we can control how each color is for each class. For example:

arr1 = [1, 2, 3, 4, 5]
arr2 = [2, 3, 3, 4, 4]
labl = [0, 1, 1, 0, 0]
color= ['red' if l == 0 else 'green' for l in labl]
plt.scatter(arr1, arr2, color=color)

I had the same problem:

curl -v -H "Content-Type: application/json" -X PUT -d '{"name":"json","surname":"gson","married":true,"age":32,"salary":123,"hasCar":true,"childs":["serkan","volkan","aybars"]}' XXXXXX/ponyo/UserModel/json

I resolved it by adding the dependency to pom.xml as follows. Please try it.

    <dependency>
        <groupId>com.owlike</groupId>
        <artifactId>genson</artifactId>
        <version>0.98</version>
    </dependency>

you may also want to encode and decode to/from base64

    function uncompress(str:String):ByteArray {
            import mx.utils.Base64Decoder;
            var dec:Base64Decoder = new Base64Decoder();
            dec.decode(str);
            var newByteArr:ByteArray=dec.toByteArray();        
            return newByteArr;
        }


    // Compress a ByteArray into a Base64 String.
    function compress(bytes:ByteArray):String { 
        import mx.utils.Base64Decoder; //Transform String in a ByteArray.
        import mx.utils.Base64Encoder; //Transform ByteArray in a readable string.
        var enc:Base64Encoder = new Base64Encoder();    
        enc.encodeBytes(bytes);
        return enc.drain().split("\n").join("");
    }

Suppose,

let a = 123456

First we will convert it into string and then apply split to convert it into array of characters and then map over it to convert the array to integer.

let b = a.toString().split('').map(val=>parseInt(val))
console.log(b)

This works using regex.

String text = "I love you so much";
String wordToFind = "love";
Pattern word = Pattern.compile(wordToFind);
Matcher match = word.matcher(text);

while (match.find()) {
     System.out.println("Found love at index "+ match.start() +" - "+ (match.end()-1));
}

Output :

Found 'love' at index 2 - 5

General Rule :

• Regex search left to right, and once the match characters has been used, it cannot be reused.

I have created a responsive sample that works well for me and I find it to be quite simple have a look at my carousel-fill:

.carousel-fill {
    height: -o-calc(100vh - 165px) !important;
    height: -webkit-calc(100vh - 165px) !important;
    height: -moz-calc(100vh - 165px) !important;
    height: calc(100vh - 165px) !important;
    width: auto !important;
    overflow: hidden;
    display: inline-block;
    text-align: center;
}

.carousel-item {
    text-align: center !important;
}

my navigation height+footer are a hair less then 165px so that value works for me. take off a value that fits for you, I overrdide the .carousel-item from bootstrap so make sure by videos are centered.

my carousel looks like this, note the "carousel-fill" on the video tag.

<div>
        <div id="myCarousel" class="carousel slide carousel-fade text-center" data-ride="carousel">

in case some one needs to control the videos like i do, I start and stop the videos like this:

<script language="JavaScript" type="text/javascript">
        $(document).ready(function () {
            $('.carousel').carousel({ interval: 8000 })
            $('#myCarousel').on('slide.bs.carousel', function (args) {
                var videoList = document.getElementsByTagName("video");
                switch (args.from) {
                    case 0:
                        videoList[0].pause();
                        break;
                    case 1:
                        videoList[1].pause();
                        break;
                    case 2:
                        videoList[2].pause();
                        break;
                }
                switch (args.to) {
                    case 0:
                        videoList[0].play();

                        break;
                    case 1:
                        videoList[1].play();
                        break;
                    case 2:
                        videoList[2].play();
                        break;

            })

        });

Another way :

change BOT_USER_NAME before use

https://telegram.me/BOT_USER_NAME?startgroup=true

Idiomatic Solution:

final Set<Double> doubles; // boilerplate
final Iterator<Double> iterator = doubles.iterator();
for (int ordinal = 0; iterator.hasNext(); ordinal++)
{
    System.out.printf("%d:%f",ordinal,iterator.next());
    System.out.println();
}

this is actually the solution that Google suggests in the Guava discussion on why they did not provide a CountingIterator.

You can use itertools.tee and zip to efficiently build the result:

from itertools import tee
# python2 only:
#from itertools import izip as zip

def differences(seq):
    iterable, copied = tee(seq)
    next(copied)
    for x, y in zip(iterable, copied):
        yield y - x

Or using itertools.islice instead:

from itertools import islice

def differences(seq):
    nexts = islice(seq, 1, None)
    for x, y in zip(seq, nexts):
        yield y - x

You can also avoid using the itertools module:

def differences(seq):
    iterable = iter(seq)
    prev = next(iterable)
    for element in iterable:
        yield element - prev
        prev = element

All these solution work in constant space if you don't need to store all the results and support infinite iterables.

Here are some micro-benchmarks of the solutions:

In [12]: L = range(10**6)

In [13]: from collections import deque
In [15]: %timeit deque(differences_tee(L), maxlen=0)
10 loops, best of 3: 122 ms per loop

In [16]: %timeit deque(differences_islice(L), maxlen=0)
10 loops, best of 3: 127 ms per loop

In [17]: %timeit deque(differences_no_it(L), maxlen=0)
10 loops, best of 3: 89.9 ms per loop

And the other proposed solutions:

In [18]: %timeit [x[1] - x[0] for x in zip(L[1:], L)]
10 loops, best of 3: 163 ms per loop

In [19]: %timeit [L[i+1]-L[i] for i in range(len(L)-1)]
1 loops, best of 3: 395 ms per loop

In [20]: import numpy as np

In [21]: %timeit np.diff(L)
1 loops, best of 3: 479 ms per loop

In [35]: %%timeit
    ...: res = []
    ...: for i in range(len(L) - 1):
    ...:     res.append(L[i+1] - L[i])
    ...: 
1 loops, best of 3: 234 ms per loop

Note that:

• zip(L[1:], L) is equivalent to zip(L[1:], L[:-1]) since zip already terminates on the shortest input, however it avoids a whole copy of L.
• Accessing the single elements by index is very slow because every index access is a method call in python

• numpy.diff is slow because it has to first convert the list to a ndarray. Obviously if you start with an ndarray it will be much faster:

  In [22]: arr = np.array(L)
  
  In [23]: %timeit np.diff(arr)
  100 loops, best of 3: 3.02 ms per loop
  

Use this

long startTime = System.currentTimeMillis();
long elapsedTime = 0L.

while (elapsedTime < 2*60*1000) {
    //perform db poll/check
    elapsedTime = (new Date()).getTime() - startTime;
}

//Throw your exception

A simple string.Concat() is what you need.

string[] test = new string[2];

test[0] = "Hello ";
test[1] = "World!";

string result = string.Concat(test);

If you also need to add a seperator (space, comma etc) then, string.Join() should be used.

string[] test = new string[2];

test[0] = "Red";
test[1] = "Blue";

string result = string.Join(",", test);

If you have to perform this on a string array with hundereds of elements than string.Join() is better by performace point of view. Just give a "" (blank) argument as seperator. StringBuilder can also be used for sake of performance, but it will make code a bit longer.

Support Python2&3 using hook (from https://stackoverflow.com/a/33571117/558397)

import requests
import six
from six import iteritems

requests.packages.urllib3.disable_warnings()  # @UndefinedVariable
r = requests.get("http://echo.jsontest.com/key/value/one/two/three", verify=False)

def _byteify(data):
    # if this is a unicode string, return its string representation
    if isinstance(data, six.string_types):
        return str(data.encode('utf-8').decode())

    # if this is a list of values, return list of byteified values
    if isinstance(data, list):
        return [ _byteify(item) for item in data ]

    # if this is a dictionary, return dictionary of byteified keys and values
    # but only if we haven't already byteified it
    if isinstance(data, dict):
        return {
            _byteify(key): _byteify(value) for key, value in iteritems(data)
        }
    # if it's anything else, return it in its original form
    return data

w = r.json(object_hook=_byteify)
print(w)

Returns:

 {'three': '', 'key': 'value', 'one': 'two'}
