I had this issue with WordPress on cloud9. It turns out it was the W3 Caching plugin. I disabled the plugin and it worked fine.

If your are not in a session you can just nextval('you_sequence_name') and it's just fine.

Check the below lines are present in your web.config file

<system.web> <httpRuntime requestPathInvalidCharacters="" /> </system.web>

This way optimizes for readability, but it's not as efficient in terms of database queries:

# Retrieve all topics, then use array subtraction to
# find the ones not in our list
Topic.all - @forums.map(&:id)

var a= [1, 2, 3, '3'];
var b = [1, 2, 3];

var c = a.filter(function (i) { return ! ~b.indexOf(i); });

alert(c.length);

You can use : ?+?+K to show keyboard on simulator.

Try os.path.splitext it should do what you want.

import os
print os.path.splitext('/home/user/somefile.txt')[0]+'.jpg'

1) Correct

2) You can think of that one as "read only" list, where you don't care about the type of the items.Could e.g. be used by a method that is returning the length of the list.

3) T, E and U are the same, but people tend to use e.g. T for type, E for Element, V for value and K for key. The method that compiles says that it took an array of a certain type, and returns an array of the same type.

4) You can't mix oranges and apples. You would be able to add an Object to your String list if you could pass a string list to a method that expects object lists. (And not all objects are strings)

A Float represents double in SQL server. You can find a proof from the coding in C# in visual studio. Here I have declared Overtime as a Float in SQL server and in C#. Thus I am able to convert

int diff=4;
attendance.OverTime = Convert.ToDouble(diff);

Here OverTime is declared float type

By setting the scale, you decrease the precision. Try NUMBER(16,2).

To add to what Evan said: C does not have a built-in operator for exponentiation, because it is not a primitive operation for most CPUs. Thus, it's implemented as a library function.

Also, for computing the function e^x, you can use the exp(double), expf(float), and expl(long double) functions.

Note that you do not want to use the ^ operator, which is the bitwise exclusive OR operator.

private int user_movie_matrix[][];Th. should be `private int user_movie_matrix[][];.

private int user_movie_matrix[][]; should be private static int user_movie_matrix[][];

cfiltering(numberOfUsers, numberOfMovies); should be new cfiltering(numberOfUsers, numberOfMovies);

Whether or not the code works as intended after these changes is beyond the scope of this answer; there were several syntax/scoping errors.

Try converting your procedure in to an Inline Function which returns a table as follows:

CREATE FUNCTION MyProc()
RETURNS TABLE AS
RETURN (SELECT * FROM MyTable)

And then you can call it as

SELECT * FROM MyProc()

You also have the option of passing parameters to the function as follows:

CREATE FUNCTION FuncName (@para1 para1_type, @para2 para2_type , ... ) 

And call it

SELECT * FROM FuncName ( @para1 , @para2 )

You can try this
SELECT * FROM Buses WHERE BusID in (1,2,3,4,...)

Use the PercentRelativeLayout or PercentFrameLayout from the Percent Supoort Library

<android.support.percent.PercentFrameLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
     <TextView
          android:layout_width="match_parent"
          app:layout_heightPercent="68%"/>
     <Gallery 
          android:id="@+id/gallery"
          android:layout_width="match_parent"
          app:layout_heightPercent="16%"/>
     <TextView
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:layout_width="match_parent"/>
</android.support.percent.PercentFrameLayout>

I am on Windows 7 using node.js v0.10.0 and mocha v1.8.2 and npm v1.2.14. I was just trying to get mocha to use the path test/unit to find my tests, After spending to long and trying several things I landed,

Using the "test/unit/*.js" option does not work on windows. For good reasons that windows shell doesn't expand wildcards like unixen.

However using "test/unit" does work, without the file pattern. eg. "mocha test/unit" runs all files found in test/unit folder.

This only still runs one folder files as tests but you can pass multiple directory names as parameters.

Also to run a single test file you can specify the full path and filename. eg. "mocha test/unit/mytest1.js"

I actually setup in package.json for npm "scripts": { "test": "mocha test/unit" },

So that 'npm test' runs my unit tests.

Try using background-size but using TWO ARGUMENTS One for the width and the other one for the height

background-image:url('../images/bg.png'); 
background-repeat:no-repeat;
background-size: 100% 100%; // Here the first argument will be the width 
// and the second will be the height.
background-position:center;

To check for an exact match you would use num == line. But line has an end-of-line character \n or \r\n which will not be in num since raw_input strips the trailing newline. So it may be convenient to remove all whitespace at the end of line with

line = line.rstrip()

with open("file.txt") as search:
    for line in search:
        line = line.rstrip()  # remove '\n' at end of line
        if num == line:
            print(line )

Instead of concatenating paths like in some answers, I use File.expand_path:

Dir[File.expand_path('importers/*.rb', File.dirname(__FILE__))].each do |file|
  require file
end

Update:

Instead of using File.dirname you could do the following:

Dir[File.expand_path('../importers/*.rb', __FILE__)].each do |file|
  require file
end

Where .. strips the filename of __FILE__.

remember, SSL/TLS operates at the Transport Layer, so all the crypto goo happens under the application-layer HTTP stuff.

that's the long way of saying, "Yes!"

Tail Recursion is pretty fast as compared to normal recursion. It is fast because the output of the ancestors call will not be written in stack to keep the track. But in normal recursion all the ancestor calls output written in stack to keep the track.

tl;dr: For modern browsers, just use

input.value = '';

Old answer:

How about:

input.type = "text";
input.type = "file";

I still have to understand why this does not work with webkit.

Anyway, this works with IE9>, Firefox and Opera.
The situation with webkit is that I seem to be unable to change it back to file.
With IE8, the situation is that it throws a security exception.

Edit: For webkit, Opera and firefox this works, though:

input.value = '';

(check the above answer with this proposal)

I'll see if I can find a nice cleaner way of doing this cross-browser without the need of the GC.

Edit2:

try{
    inputs[i].value = '';
    if(inputs[i].value){
        inputs[i].type = "text";
        inputs[i].type = "file";
    }
}catch(e){}

Works with most browsers. Does not work with IE < 9, that's all.
Tested on firefox 20, chrome 24, opera 12, IE7, IE8, IE9, and IE10.

db.Lead.find(

{"name": {'$regex' : '.*' + "Ravi" + '.*'}},
{
"$or": [{
    'added_by':"[email protected]"
}, {
    'added_by':"[email protected]"
}]
}

);

Update for .NET Framework 4.5 and 4.6; the following will no longer work:

string keyvalue = System.Configuration.ConfigurationManager.AppSettings["keyname"];

Now access the Setting class via Properties:

string keyvalue = Properties.Settings.Default.keyname;

See Managing Application Settings for more information.

To achieve what you are looking for you can use the viewport-percentage length vw.

Here is a quick example I made on jsfiddle.

HTML:

<div class="square">
    <h1>This is a Square</h1>
</div>

CSS:

.square {
    background: #000;
    width: 50vw;
    height: 50vw;
}
.square h1 {
    color: #fff;
}

I am sure there are many other ways to do this but this way seemed the best to me.

Objects does not support push property, but you can save it as well using the index as key,

var tempData = {};_x000D_
for ( var index in data ) {_x000D_
  if ( data[index].Status == "Valid" ) { _x000D_
    tempData[index] = data; _x000D_
  } _x000D_
 }_x000D_
data = tempData;

I think this is easier if remove the object if its status is invalid, by doing.

for(var index in data){_x000D_
  if(data[index].Status == "Invalid"){ _x000D_
    delete data[index]; _x000D_
  } _x000D_
}

And finally you don't need to create a var temp –

Twisted has SSH support : http://www.devshed.com/c/a/Python/SSH-with-Twisted/

The twisted.conch package adds SSH support to Twisted. This chapter shows how you can use the modules in twisted.conch to build SSH servers and clients.

Setting Up a Custom SSH Server

The command line is an incredibly efficient interface for certain tasks. System administrators love the ability to manage applications by typing commands without having to click through a graphical user interface. An SSH shell is even better, as it’s accessible from anywhere on the Internet.

You can use twisted.conch to create an SSH server that provides access to a custom shell with commands you define. This shell will even support some extra features like command history, so that you can scroll through the commands you’ve already typed.

How Do I Do That? Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver , but with higher-level features for controlling the terminal.

Write a subclass of twisted.conch.recvline.HistoricRecvLine that implements your shell protocol. HistoricRecvLine is similar to twisted.protocols.basic.LineReceiver, but with higher-level features for controlling the terminal.

To make your shell available through SSH, you need to implement a few different classes that twisted.conch needs to build an SSH server. First, you need the twisted.cred authentication classes: a portal, credentials checkers, and a realm that returns avatars. Use twisted.conch.avatar.ConchUser as the base class for your avatar. Your avatar class should also implement twisted.conch.interfaces.ISession , which includes an openShell method in which you create a Protocol to manage the user’s interactive session. Finally, create a twisted.conch.ssh.factory.SSHFactory object and set its portal attribute to an instance of your portal.

Example 10-1 demonstrates a custom SSH server that authenticates users by their username and password. It gives each user a shell that provides several commands.

Example 10-1. sshserver.py

I have managed to to do it in a way. Perform all the steps as referenced by Michal Rowicki above.

1. Open Visual Paradigm software.
2. Create a new Project
3. There would be an option on the Tools bar above that states Code and select Instant Reverse... from the drop down menu with Java language(or other)
4. Select your application folder where your project is located and add it to the project(i have selected the complete folder application)
5. The application should now appear on the left pane in Class Repository
6. Then all you do is right click the project that you have added and select Reverse to new class diagram
7. Select either you wish to have the packages included in the class diagram or just the class diagram of the project

Then it should appear on your screen and customize it as you wish

However i do not know if the plugin in Android Studio was necessary nevertheless it has worked in a way for me.

Alert boxes in JavaScript can only display pure text. You could use a JavaScript library like jQuery to display a modal instead?

This might be useful: http://jqueryui.com/dialog/

You can do it like this:

<head>
  <meta charset="utf-8" />
  <title>jQuery UI Dialog - Default functionality</title>
  <link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />

    font-size: 62.5%;
}

  </script>
  <script>
  $(function() {
    $( "#dialog" ).dialog();
  });
  </script>

I was just searching for something similar:

I want to sum every odd row column.

SUMIF has TWO possible ranges, the range to sum from, and a range to consider criteria in.

SUMIF(B1:B1000,1,A1:A1000)

This function will consider if a cell in the B range is "=1", it will sum the corresponding A cell only if it is.

To get "=1" to return in the B range I put this in B:

=MOD(ROWNUM(B1),2)

Then auto fill down to get the modulus to fill, you could put and calculatable criteria here to get the SUMIF or SUMIFS conditions you need to loop through each cell.

Easier than ARRAY stuff and hides the back-end of loops!

I think this can work with json files too if you change the mime type.

The main method is the entry point of a Java application.

Specifically?when the Java Virtual Machine is told to run an application by specifying its class (by using the java application launcher), it will look for the main method with the signature of public static void main(String[]).

From Sun's java command page:

The java tool launches a Java application. It does this by starting a Java runtime environment, loading a specified class, and invoking that class's main method.

The method must be declared public and static, it must not return any value, and it must accept a String array as a parameter. The method declaration must look like the following:

public static void main(String args[])

For additional resources on how an Java application is executed, please refer to the following sources:

1. Chapter 12: Execution from the Java Language Specification, Third Edition.
2. Chapter 5: Linking, Loading, Initializing from the Java Virtual Machine Specifications, Second Edition.
3. A Closer Look at the "Hello World" Application from the Java Tutorials.

The run method is the entry point for a new Thread or an class implementing the Runnable interface. It is not called by the Java Virutal Machine when it is started up by the java command.

As a Thread or Runnable itself cannot be run directly by the Java Virtual Machine, so it must be invoked by the Thread.start() method. This can be accomplished by instantiating a Thread and calling its start method in the main method of the application:

public class MyRunnable implements Runnable
{
    public void run()
    {
        System.out.println("Hello World!");
    }

    public static void main(String[] args)
    {
        new Thread(new MyRunnable()).start();
    }
}

For more information and an example of how to start a subclass of Thread or a class implementing Runnable, see Defining and Starting a Thread from the Java Tutorials.

The init method is the first method called in an Applet or JApplet.

When an applet is loaded by the Java plugin of a browser or by an applet viewer, it will first call the Applet.init method. Any initializations that are required to use the applet should be executed here. After the init method is complete, the start method is called.

For more information about when the init method of an applet is called, please read about the lifecycle of an applet at The Life Cycle of an Applet from the Java Tutorials.

We face this error when we are selecting data from more than one tables by joining tables and at least one of the selected columns (it will also happen when use * to select all columns) exist with same name in more than one tables (our selected/joined tables). In that case we must have to specify from which table we are selecting out column.

Following is a an example solution implementation of concept explained above

I think you have ambiguity only in InvoiceID that exists both in InvoiceLineItems and Invoices Other fields seem distinct. So try This

I just replace InvoiceID with Invoices.InvoiceID

   SELECT 
        VendorName, Invoices.InvoiceID, InvoiceSequence, InvoiceLineItemAmount
    FROM Vendors 
    JOIN Invoices ON (Vendors.VendorID = Invoices.VendorID)
    JOIN InvoiceLineItems ON (Invoices.InvoiceID = InvoiceLineItems.InvoiceID)
    WHERE  
        Invoices.InvoiceID IN
            (SELECT InvoiceSequence 
             FROM InvoiceLineItems
             WHERE InvoiceSequence > 1)
    ORDER BY 
        VendorName, Invoices.InvoiceID, InvoiceSequence, InvoiceLineItemAmount

You can use tablename.columnnae for all columns (in selection,where,group by and order by) without using any alias. However you can use an alias as guided by other answers

This should work to get a specific column out of the command output "docker images":

This is going to print the third column

Mostly disabled attribute doesn't work with the anchor tags from HTML-5 onwards. Hence we have change it to ,let's say 'button' and style it accordingly with appropriate color,border-style etc. That's the most apt solution for any similar issue users are facing in Chrome . Only few elements support 'disabled' attribute: Span , select, option, textarea, input , button.

Use the Below Code for that

UPDATE Table1 SET Column1 = LTRIM(RTRIM(REPLACE(REPLACE(REPLACE(Column1, CHAR(9), ''), CHAR(10), ''), CHAR(13), '')))`

Yes.

KVO requires dynamic dispatch, so you simply need to add the dynamic modifier to a method, property, subscript, or initializer:

dynamic var foo = 0

The dynamic modifier ensures that references to the declaration will be dynamically dispatched and accessed through objc_msgSend.

As posted in my update above, a potential solution would be to use Declaration Merging as suggested by @Tyler-sebastion. I was able to define two additional interfaces and add the index property on the EventTarget in this way.

interface KonvaTextEventTarget extends EventTarget {
  index: number
}

interface KonvaMouseEvent extends React.MouseEvent<HTMLElement> {
  target: KonvaTextEventTarget
}

I then can declare the event as KonvaMouseEvent in my onclick MouseEventHandler function.

onClick={(event: KonvaMouseEvent) => {
          makeMove(ownMark, event.target.index)
}}

I'm still not 100% if this is the best approach as it feels a bit Kludgy and overly verbose just to get past the tslint error.

the mysqli_queryexcepts 2 parameters , first variable is mysqli_connectequivalent variable , second one is the query you have provided

$name1 = mysqli_connect(localhost,tdoylex1_dork,dorkk,tdoylex1_dork);

$name2 = mysqli_query($name1,"SELECT name FROM users ORDER BY RAND() LIMIT 1");

Adding additional information to emboss's answer.

To put it simply, there is an incorrect cert in your certificate chain.

For example, your certificate authority will have most likely given you 3 files.

• your_domain_name.crt
• DigiCertCA.crt # (Or whatever the name of your certificate authority is)
• TrustedRoot.crt

You most likely combined all of these files into one bundle.

-----BEGIN CERTIFICATE----- 
(Your Primary SSL certificate: your_domain_name.crt) 
-----END CERTIFICATE----- 
-----BEGIN CERTIFICATE----- 
(Your Intermediate certificate: DigiCertCA.crt) 
-----END CERTIFICATE----- 
-----BEGIN CERTIFICATE----- 
(Your Root certificate: TrustedRoot.crt) 
-----END CERTIFICATE-----

If you create the bundle, but use an old, or an incorrect version of your Intermediate Cert (DigiCertCA.crt in my example), you will get the exact symptoms you are describing.

• SSL connections appear to work from browser
• SSL connections fail from other clients
• Curl fails with error: "curl: (60) SSL certificate : unable to get local issuer certificate"
• openssl s_client -connect gives error "verify error:num=20:unable to get local issuer certificate"

Redownload all certs from your certificate authority and make a fresh bundle.

Use the following Imports

Imports System.Data.SqlClient
Imports System.Data.Sql

Public SQLConn As New SqlConnection With {.ConnectionString = "Server=Desktop1[enter image description here][1];Database=Infostudio; Trusted_Connection=true;"}

Full string:

Criteria is an object-oriented API, while HQL means string concatenation. That means all of the benefits of object-orientedness apply:

1. All else being equal, the OO version is somewhat less prone to error. Any old string could get appended into the HQL query, whereas only valid Criteria objects can make it into a Criteria tree. Effectively, the Criteria classes are more constrained.
2. With auto-complete, the OO is more discoverable (and thus easier to use, for me at least). You don't necessarily need to remember which parts of the query go where; the IDE can help you
3. You also don't need to remember the particulars of the syntax (like which symbols go where). All you need to know is how to call methods and create objects.

Since HQL is very much like SQL (which most devs know very well already) then these "don't have to remember" arguments don't carry as much weight. If HQL was more different, then this would be more importatnt.

Ok, I think for a novice things might be a bit confusing. I think the correct answer is a mix of all the above, at least in Swift4.

Either create an extension or use the ViewController in which you'd like to use this but make sure to implement UITextFieldDelegate. For reusability's sake I found it easier to use an extension:

extension UIViewController : UITextFieldDelegate {
    ...
}

but the alternative works as well:

class MyViewController: UIViewController {
    ...
}

Add the method textFieldShouldReturn (depending on your previous option, either in the extension or in your ViewController)

func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    return textField.endEditing(false)
}

In your viewDidLoad method, set the textfield's delegate to self

@IBOutlet weak var myTextField: UITextField!
...

override func viewDidLoad() {
    ..
    myTextField.delegte = self;
    ..
}

That should be all. Now, when you press return the textFieldShouldReturn should be called.

You can use jquery animate function for that.

$({ countNum: $('.code').html() }).animate({ countNum: 4000 }, {
        duration: 8000,
        easing: 'linear',
        step: function () {
        $('.code').html(Math.floor(this.countNum) );
        },
        complete: function () {
        $('.code').html(this.countNum);
        //alert('finished');
        }
    });

Blaze meter has a chrome extension for recording sessions and exporting them to JMeter (currently requires login). You also have the option of paying them money to run it on their cluster of JMeter servers (their pricing seems much better than LoadImpact which I've just stopped using):

• BlazeMeter Chrome Extension
• Blog entry about it

I don't have any association with them, I just like the look of their service, although I haven't used the paid version yet.

It is worth noting that the accepted answer will round small floats down to zero.

>>> import numpy as np 
>>> arr = np.asarray([2.92290007e+00, -1.57376965e-03, 4.82011728e-08, 1.92896977e-12])
>>> print(arr)
[ 2.92290007e+00 -1.57376965e-03  4.82011728e-08  1.92896977e-12]
>>> np.round(arr, 2)
array([ 2.92, -0.  ,  0.  ,  0.  ]) 

You can use set_printoptions and a custom formatter to fix this and get a more numpy-esque printout with fewer decimal places:

>>> np.set_printoptions(formatter={'float': "{0:0.2e}".format})
>>> print(arr)
[2.92e+00 -1.57e-03 4.82e-08 1.93e-12]  

This way, you get the full versatility of format and maintain the full precision of numpy's datatypes.

Also note that this only affects printing, not the actual precision of the stored values used for computation.

Add this at the start of main

ApplicationContext context = new ClassPathXmlApplicationContext("path/to/applicationContext.xml");

JobLauncher launcher=(JobLauncher)context.getBean("launcher");
Job job=(Job)context.getBean("job");

//Get as many beans you want
//Now do the thing you were doing inside test method
StopWatch sw = new StopWatch();
sw.start();
launcher.run(job, jobParameters);
sw.stop();
//initialize the log same way inside main
logger.info(">>> TIME ELAPSED:" + sw.prettyPrint());

One can simply use the pydoc.locate function.

from pydoc import locate
my_class = locate("module.submodule.myclass")
instance = my_class()

At a very high level:

Abstraction of any kind comes down to separating concerns. "Client" code of an abstraction doesn't care how the contract exposed by the abstraction is fulfilled. You usually don't care if a string class uses a null-terminated or buffer-length-tracked internal storage implementation, for example. Encapsulation hides the details, but by making classes/methods/etc. abstract, you allow the implementation to change or for new implementations to be added without affecting the client code.

The .pid is the processid of the running mysql server instance. It appears in the data folder when mysql is running and removes itself when mysql is shutdown.

If the OSX operating system is upgraded and mysql is not shutdown properly before the upgrade,mysql quits when it started up it just quits because of the .pid file.

There are a few tricks you can try, http://coolestguidesontheplanet.com/mysql-error-server-quit-without-updating-pid-file/ failing these a reinstall is needed.

Here is the complete answer to the question.

import java.util.Arrays;
import java.util.Iterator;
import java.util.List;
import java.util.NoSuchElementException;

class ListIterator implements Iterator<String>{
    List<String> list;
    int pos = 0;

    public ListIterator(List<String> list) {
        this.list = list;
    }

    @Override
    public boolean hasNext() {
        while(pos < list.size()){
            if (list.get(pos).startsWith("a"))
                return true;
            pos++;
        }
        return false;

    }

    @Override
    public String next() {
        if (hasNext())
            return list.get(pos++);
        throw new NoSuchElementException();
    }
}

public class IteratorTest {

    public static void main(String[] args) {
        List<String> list = Arrays.asList("alice", "bob", "abigail", "charlie");
        ListIterator itr = new ListIterator(list);

        while(itr.hasNext())
            System.out.println(itr.next()); // prints alice, abigail
    }
}

• ListIterator is the iterator for the array which returns the elements that start with 'a'.
• There is no need for implementing an Iterable interface. But that is a possibility.
• There is no need to implement this generically.
• It fully satisfies the contract for hasNext() and next(). ie if hasNext() says there are still elements, next() will return those elements. And if hasNext() says no more elements, it returns a valid NoSuchElementException exception.

you need edit setting.json file,

settings.json, located at

Windows %APPDATA%\Code\User\settings.json
macOS $HOME/Library/Application Support/Code/User/settings.json
Linux $HOME/.config/Code/User/settings.json


        {
          "workbench.editor.showTabs": true,
          "workbench.editor.enablePreview": false
        }

There is a php library (pdfparser) that does exactly what you want.

project website

http://www.pdfparser.org/

github

https://github.com/smalot/pdfparser

Demo page/api

http://www.pdfparser.org/demo

After including pdfparser in your project you can get all text from mypdf.pdf like so:

<?php
$parser = new \installpath\PdfParser\Parser();
$pdf    = $parser->parseFile('mypdf.pdf');  
$text = $pdf->getText();
echo $text;//all text from mypdf.pdf

?>

Simular you can get the metadata from the pdf as wel as getting the pdf objects (for example images).

If you don't want to override your router (if you don't have your app configured in a way that supports this, or want to configure CORS on a route by route basis), add an OPTIONS handler to handle the pre flight request.

Ie, with Gorilla Mux your routes would look like:

accounts := router.Path("/accounts").Subrouter()
accounts.Methods("POST").Handler(AccountsCreate)
accounts.Methods("OPTIONS").Handler(AccountsCreatePreFlight)

Note above that in addition to our POST handler, we're defining a specific OPTIONS method handler.

And then to actual handle the OPTIONS preflight method, you could define AccountsCreatePreFlight like so:

// Check the origin is valid.
origin := r.Header.Get("Origin")
validOrigin, err := validateOrigin(origin)
if err != nil {
    return err
}

// If it is, allow CORS.
if validOrigin {
    w.Header().Set("Access-Control-Allow-Origin", origin)
    w.Header().Set("Access-Control-Allow-Methods", "POST")
    w.Header().Set("Access-Control-Allow-Headers",
        "Accept, Content-Type, Content-Length, Accept-Encoding, X-CSRF-Token, Authorization")
}

What really made this all click for me (in addition to actually understanding how CORS works) is that the HTTP Method of a preflight request is different from the HTTP Method of the actual request. To initiate CORS, the browser sends a preflight request with HTTP Method OPTIONS, which you have to handle explicitly in your router, and then, if it receives the appropriate response "Access-Control-Allow-Origin": origin (or "*" for all) from your application, it initiates the actual request.

I also believe that you can only do "*" for standard types of requests (ie: GET), but for others you'll have to explicitly set the origin like I do above.

While generating release Hash key, Note this

For Windows

When generating the hash key for production you need to use openssl-0.9.8e_X64.zip on windows, you cannot use openssl-0.9.8k_X64.zip

The versions produce different hash keys, for some reason 9.8k does not work correctly... 9.8e does.

I want to give an example which others haven't mentioned

* can also unpack a generator

An example from Python3 Document

x = [1, 2, 3]
y = [4, 5, 6]

unzip_x, unzip_y = zip(*zip(x, y))

unzip_x will be [1, 2, 3], unzip_y will be [4, 5, 6]

The zip() receives multiple iretable args, and return a generator.

zip(*zip(x,y)) -> zip((1, 4), (2, 5), (3, 6))

There is no need to invoke PHP for this. Just put it directly into the HTML:

<a href="http://www.example.com/">...

If you want make a border in a shape xml. You need to use:

For the external border,you need to use:

<stroke/>

For the internal background,you need to use:

<solid/>

If you want to set corners,you need to use:

<corners/>

If you want a padding betwen border and the internal elements,you need to use:

<padding/>

Here is a shape xml example using the above items. It works for me

<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
  <stroke android:width="2dp" android:color="#D0CFCC" /> 
  <solid android:color="#F8F7F5" /> 
  <corners android:radius="10dp" />
  <padding android:left="2dp" android:top="2dp" android:right="2dp" android:bottom="2dp" />
</shape>

Cheap and cheerful answer:

<textarea>Some raw content</textarea>

The textarea will handle tabs, multiple spaces, newlines, line wrapping all verbatim. It copies and pastes nicely and its valid HTML all the way. It also allows the user to resize the code box. You don't need any CSS, JS, escaping, encoding.

You can alter the appearance and behaviour as well. Here's a monospace font, editing disabled, smaller font, no border:

<textarea
    style="width:100%; font-family: Monospace; font-size:10px; border:0;"
    rows="30" disabled
>Some raw content</textarea>

This solution is probably not semantically correct. So if you need that, it might be best to choose a more sophisticated answer.

Update

Not knowing what you are trying to do, I'll share one more suggestion: Preallocate vectors of the type you want for each column, insert values into those vectors, and then, at the end, create your data.frame.

Continuing with Julian's f3 (a preallocated data.frame) as the fastest option so far, defined as:

# pre-allocate space
f3 <- function(n){
  df <- data.frame(x = numeric(n), y = character(n), stringsAsFactors = FALSE)
  for(i in 1:n){
    df$x[i] <- i
    df$y[i] <- toString(i)
  }
  df
}

Here's a similar approach, but one where the data.frame is created as the last step.

# Use preallocated vectors
f4 <- function(n) {
  x <- numeric(n)
  y <- character(n)
  for (i in 1:n) {
    x[i] <- i
    y[i] <- i
  }
  data.frame(x, y, stringsAsFactors=FALSE)
}

microbenchmark from the "microbenchmark" package will give us more comprehensive insight than system.time:

library(microbenchmark)
microbenchmark(f1(1000), f3(1000), f4(1000), times = 5)
# Unit: milliseconds
#      expr         min          lq      median         uq         max neval
#  f1(1000) 1024.539618 1029.693877 1045.972666 1055.25931 1112.769176     5
#  f3(1000)  149.417636  150.529011  150.827393  151.02230  160.637845     5
#  f4(1000)    7.872647    7.892395    7.901151    7.95077    8.049581     5

f1() (the approach below) is incredibly inefficient because of how often it calls data.frame and because growing objects that way is generally slow in R. f3() is much improved due to preallocation, but the data.frame structure itself might be part of the bottleneck here. f4() tries to bypass that bottleneck without compromising the approach you want to take.

Original answer

This is really not a good idea, but if you wanted to do it this way, I guess you can try:

for (i in 1:10) {
  df <- rbind(df, data.frame(x = i, y = toString(i)))
}

Note that in your code, there is one other problem:

• You should use stringsAsFactors if you want the characters to not get converted to factors. Use: df = data.frame(x = numeric(), y = character(), stringsAsFactors = FALSE)

The Kotlin way by using builtin Extension function on File

Write: yourFile.writeText(textFromEditText)
Read: yourFile.readText()

You can always do

('0' + deg).slice(-2)

See slice():

You can also use negative numbers to select from the end of an array

Hence

('0' + 11).slice(-2) // '11'
('0' + 4).slice(-2)  // '04'

For ease of access, you could of course extract it to a function, or even extend Number with it:

Number.prototype.pad = function(n) {
    return new Array(n).join('0').slice((n || 2) * -1) + this;
}

Which will allow you to write:

c += deg.pad() + '° '; // "04° "

The above function pad accepts an argument specifying the length of the desired string. If no such argument is used, it defaults to 2. You could write:

deg.pad(4) // "0045"

Note the obvious drawback that the value of n cannot be higher than 11, as the string of 0's is currently just 10 characters long. This could of course be given a technical solution, but I did not want to introduce complexity in such a simple function. (Should you elect to, see alex's answer for an excellent approach to that).

Note also that you would not be able to write 2.pad(). It only works with variables. But then, if it's not a variable, you'll always know beforehand how many digits the number consists of.

A good alternative is this:

find . -type f | xargs chmod -v 644

and for directories:

find . -type d | xargs chmod -v 755

and to be more explicit:

find . -type f | xargs -I{} chmod -v 644 {}

Create a table layout panel with two columns in your form and name it tlpFields.

Then, simply add new control to table layout panel (in this case I added 5 labels in column-1 and 5 textboxes in column-2).

tlpFields.RowStyles.Clear();  //first you must clear rowStyles

for (int ii = 0; ii < 5; ii++)
{
    Label l1= new Label();
    TextBox t1 = new TextBox();

    l1.Text = "field : ";

    tlpFields.Controls.Add(l1, 0, ii);  // add label in column0
    tlpFields.Controls.Add(t1, 1, ii);  // add textbox in column1

    tlpFields.RowStyles.Add(new RowStyle(SizeType.Absolute,30)); // 30 is the rows space
}

Finally, run the code.

z-index only applies to elements that have been given an explicit position. Add position:relative to #popupContent and you should be good to go.

Colin is correct that a profile should be used. However, his answer hard-codes the target directory in the profile. An alternate solution would be to add a profile like this:

    <profile>
        <id>alternateBuildDir</id>
        <activation>
            <property>
                <name>alt.build.dir</name>
            </property>
        </activation>
        <build>
            <directory>${alt.build.dir}</directory>
        </build>
    </profile>

Doing so would have the effect of changing the build directory to whatever is given by the alt.build.dir property, which can be given in a POM, in the user's settings, or on the command line. If the property is not present, the compilation will happen in the normal target directory.

First create table without auto_increment,

CREATE TABLE `members`(
    `id` int(11) NOT NULL,
    `memberid` VARCHAR( 30 ) NOT NULL ,
    `Time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ,
    `firstname` VARCHAR( 50 ) NULL ,
    `lastname` VARCHAR( 50 ) NULL
    PRIMARY KEY (memberid) 
) ENGINE = MYISAM;

after set id as index,

ALTER TABLE `members` ADD INDEX(`id`);

after set id as auto_increment,

ALTER TABLE `members` CHANGE `id` `id` INT(11) NOT NULL AUTO_INCREMENT;

Or

CREATE TABLE IF NOT EXISTS `members` (
    `id` int(11) NOT NULL,
    `memberid` VARCHAR( 30 ) NOT NULL ,
    `Time` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ,
    `firstname` VARCHAR( 50 ) NULL ,
    `lastname` VARCHAR( 50 ) NULL,
      PRIMARY KEY (`memberid`),
      KEY `id` (`id`)
) ENGINE=MYISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

Use SELECT ... INTO:

SELECT *
INTO ABC_1
FROM ABC;

This will create a new table ABC_1 that has the same column structure as ABC and contains the same data. Constraints (e.g. keys, default values), however, are -not- copied.

You can run this query multiple times with a different table name each time.

If you don't need to copy the data, only to create a new empty table with the same column structure, add a WHERE clause with a falsy expression:

SELECT *
INTO ABC_1
FROM ABC
WHERE 1 <> 1;

I'm a little late to the game, but this may help others.

In my case my jenkins master has a shared external resource, which is allocated to jenkins jobs by the external-resource-dispatcher-plugin. Due to bug JENKINS-19439 in the plugin (which is in beta), I found that my resource had been locked by a previous job, but wasn't unlocked when that previous job was cancelled.

To find out if a resource is currently in the locked state, navigate to the affected jenkins node, Jenkins -> Manage Jenkins -> Manage Nodes -> master

You should see the current state of any external resources. If any are unexpectedly locked this may be the reason why jobs are waiting for an executor.

I couldn't find any details of how to manually resolve this issue.
Restarting jenkins didn't resolve the problem.
In the end I went with the brutal approach:

• Remove the external resource
  (see Jenkins -> Manage Jenkins -> Manage Nodes -> master -> configure)
• Restart jenkins
• Re-create the external resource

You are unable to return NULL because the return type of the function is an object reference and not a pointer.

Why? One almost never needs to update the statistics. Rebuilding an index is even more rarely needed.

OPTIMIZE TABLE tbl; will rebuild the indexes and do ANALYZE; it takes time.

ANALYZE TABLE tbl; is fast for InnoDB to rebuild the stats. With 5.6.6 it is even less needed.

You need to set the logger level to the lowest you want to display. For example, if you want to display DEBUG messages, you need to set the logger level to DEBUG.

For those working with ant, I use this to indicate a pause of 5 seconds:

<tr>
    <td>pause</td>
    <td>5000</td>
    <td></td>
</tr>

That is, target: 5000 and value empty. As the reference indicates:

pause(waitTime)

Arguments:

• waitTime - the amount of time to sleep (in milliseconds)

Wait for the specified amount of time (in milliseconds)

Relying on column order is generally a bad idea in SQL. SQL is based on Relational theory where order is never guaranteed - by design. You should treat all your columns and rows as having no order and then change your queries to provide the correct results:

For Columns:

• Try not to use SELECT *, but instead specify the order of columns in the select list as in: SELECT Member_ID, MemberName, MemberAddress from TableName. This will guarantee order and will ease maintenance if columns get added.

For Rows:

• Row order in your result set is only guaranteed if you specify the ORDER BY clause.
• If no ORDER BY clause is specified the result set may differ as the Query Plan might differ or the database pages might have changed.

%d is print as an int %s is print as a string %f is print as floating point

It should be noted that it is incorrect to say that this is different from Java. Printf stands for print format, if you do a formatted print in Java, this is exactly the same usage. This may allow you to solve interesting and new problems in both C and Java!

James K, I'm sorry I was wrong in a fair portion of what I said. The test I did was the following:

@ECHO OFF
(
  :: But
   : neither
  :: does
   : this
  :: also.
)

This meets your description of alternating but fails with a ") was unexpected at this time." error message.

I did some farther testing today and found that alternating isn't the key but it appears the key is having an even number of lines, not having any two lines in a row starting with double colons (::) and not ending in double colons. Consider the following:

@ECHO OFF
(
   : But
   : neither
   : does
   : this
   : cause
   : problems.
)

This works!

But also consider this:

@ECHO OFF
(
   : Test1
   : Test2
   : Test3
   : Test4
   : Test5
   ECHO.
)

The rule of having an even number of comments doesn't seems to apply when ending in a command.

Unfortunately this is just squirrelly enough that I'm not sure I want to use it.

Really, the best solution, and the safest that I can think of, is if a program like Notepad++ would read REM as double colons and then would write double colons back as REM statements when the file is saved. But I'm not aware of such a program and I'm not aware of any plugins for Notepad++ that does that either.

I think you can use

sys.exit(0)

You may check it here in the python 2.7 doc:

The optional argument arg can be an integer giving the exit status (defaulting to zero), or another type of object. If it is an integer, zero is considered “successful termination” and any nonzero value is considered “abnormal termination” by shells and the like.

Better use $_SERVER['REQUEST_METHOD']:

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // …
}

All functions in Java are virtual by default.

You have to go out of your way to write non-virtual functions by adding the "final" keyword.

This is the opposite of the C++/C# default. Class functions are non-virtual by default; you make them so by adding the "virtual" modifier.

select DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE())-1, 0) --First day of previous month
select DATEADD(MONTH, DATEDIFF(MONTH, -1, GETDATE())-1, -1) --Last Day of previous month

You should add "throws IOException" to your main method:

public static void main(String[] args) throws IOException {

You can read a bit more about checked exceptions (which are specific to Java) in JLS.

You can use HTML5 autofocus for this. You don't need jQuery or other JavaScript.

<input type="text" name="some_field" autofocus>

Note this will not work on IE9 and lower.

Install and use PHP's GeoIP extension if you can. On debian lenny:

sudo wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
sudo gunzip GeoLiteCity.dat.gz
sudo mkdir -v /usr/share/GeoIP
sudo mv -v GeoLiteCity.dat /usr/share/GeoIP/GeoIPCity.dat

sudo apt-get install php5-geoip
# or sudo apt-get install php-geoip for PHP7

and then try it in PHP:

$ip = $_SERVER['REMOTE_ADDR'];
$country = geoip_country_name_by_name($ip);
echo 'The current user is located in: ' . $country;

returns:

The current user is located in: Cameroon

It shouldn't matter, any more than if you encoded the letter A as %41.

However, if you're dealing with a system that doesn't recognize one form, it seems like you're just going to have to give it what it expects regardless of what the "spec" says.

I posted my solution at Python implementation of "median of medians" algorithm , which is a little bit faster than using sort(). My solution uses 15 numbers per column, for a speed ~5N which is faster than the speed ~10N of using 5 numbers per column. The optimal speed is ~4N, but I could be wrong about it.

Per Tom's request in his comment, I added my code here, for reference. I believe the critical part for speed is using 15 numbers per column, instead of 5.

You can try geoplugin

Beside the geolocation done by IP (but the IP is the provider IP, so not so accurate), they return currencies also and have a currency converter: see examples.

They have 111 currencies updated.

You can use the function MROUND(<reference cell>, <round to multiple of digit needed>).

Example:

1. For a value A1 = 21 round to multiple of 10 it would be written as =MROUND(A1,10) for which Result = 20

2. For a value Z4 = 55.1 round to multiple of 10 it would be written as =MROUND(Z4,10) for which Result = 60

This probably harks from the old VB NOT .Net days when bool.ToString produced True or False.

The way that the language manages lexical scope creates issues with including both goto and continue. For example,

local a=0
repeat 
    if f() then
        a=1 --change outer a
    end
    local a=f() -- inner a
until a==0 -- test inner a

The declaration of local a inside the loop body masks the outer variable named a, and the scope of that local extends across the condition of the until statement so the condition is testing the innermost a.

If continue existed, it would have to be restricted semantically to be only valid after all of the variables used in the condition have come into scope. This is a difficult condition to document to the user and enforce in the compiler. Various proposals around this issue have been discussed, including the simple answer of disallowing continue with the repeat ... until style of loop. So far, none have had a sufficiently compelling use case to get them included in the language.

The work around is generally to invert the condition that would cause a continue to be executed, and collect the rest of the loop body under that condition. So, the following loop

-- not valid Lua 5.1 (or 5.2)
for k,v in pairs(t) do
  if isstring(k) then continue end
  -- do something to t[k] when k is not a string
end

could be written

-- valid Lua 5.1 (or 5.2)
for k,v in pairs(t) do
  if not isstring(k) then 
    -- do something to t[k] when k is not a string
  end
end

It is clear enough, and usually not a burden unless you have a series of elaborate culls that control the loop operation.

Had the same problem, nothing was helping, but I looked in Info.plist and found out that bundle ID was changed to other name (I don't know how it happened), so when I changed it to correct one everything was fine again.

I had the same problem, and found the answer. If you use node.js with express, you need to give it its own function in order for the js file to be reached. For example:

const script = path.join(__dirname, 'script.js');
const server = express().get('/', (req, res) => res.sendFile(script))

As Leo points out, the code you added to your question would not suggest a strong reference cycle (a.k.a., retain cycle). One operation-related issue that could cause a strong reference cycle would be if the operation is not getting released. While your code snippet suggests that you have not defined your operation to be concurrent, but if you have, it wouldn't be released if you never posted isFinished, or if you had circular dependencies, or something like that. And if the operation isn't released, the view controller wouldn't be released either. I would suggest adding a breakpoint or NSLog in your operation's dealloc method and confirm that's getting called.

You said:

I understand the notion of retain cycles, but I am not quite sure what happens in blocks, so that confuses me a little bit

The retain cycle (strong reference cycle) issues that occur with blocks are just like the retain cycle issues you're familiar with. A block will maintain strong references to any objects that appear within the block, and it will not release those strong references until the block itself is released. Thus, if block references self, or even just references an instance variable of self, that will maintain strong reference to self, that is not resolved until the block is released (or in this case, until the NSOperation subclass is released.

For more information, see the Avoid Strong Reference Cycles when Capturing self section of the Programming with Objective-C: Working with Blocks document.

If your view controller is still not getting released, you simply have to identify where the unresolved strong reference resides (assuming you confirmed the NSOperation is getting deallocated). A common example is the use of a repeating NSTimer. Or some custom delegate or other object that is erroneously maintaining a strong reference. You can often use Instruments to track down where objects are getting their strong references, e.g.:

Or in Xcode 5:

You can access your array keys like so:

foreach ($array as $key => $value)

I don't know what your string is, but I'm going to assume that it manages its own memory.

You have two solutions:

1: Return a struct which contains all the types you need.

struct Tuple {
    int a;
    string b;
};

struct Tuple getPair() {
    Tuple r = { 1, getString() };
    return r;
}

void foo() {
    struct Tuple t = getPair();
}

2: Use pointers to pass out values.

void getPair(int* a, string* b) {
    // Check that these are not pointing to NULL
    assert(a);
    assert(b);
    *a = 1;
    *b = getString();
}

void foo() {
    int a, b;
    getPair(&a, &b);
}

Which one you choose to use depends largely on personal preference as to whatever semantics you like more.

i have same prob too, just remove the value

<script>
      $("#play").toggle(function(){$(this).css("background","url(player.png) -100px 0px no-repeat");},
      function(){$(this).css("background","");});
</script>

In your CSS stylesheet, try adding:

input[type="text"] {
    font-size:25px;
}

The Google Guava library has a ton of helpful utilities. One of note here is the Files class. It has a bunch of useful methods including:

File myTempDir = Files.createTempDir();

This does exactly what you asked for in one line. If you read the documentation here you'll see that the proposed adaptation of File.createTempFile("install", "dir") typically introduces security vulnerabilities.

How to run Composer From Anywhere (on MacOS X) via Terminal

Background:

Actually in getComposer website it clearly states that, install the Composer by using the following curl command,

curl -sS https://getcomposer.org/installer |php

And it certainly does what it's intended to do. And then it says to move the composer.phar to the directory /usr/local/bin/composer and then composer will be available Globally, by using the following command line in terminal!

mv composer.phar /usr/local/bin/composer

Question:

So the problem which leads me to Google over it is when I executed the above line in Mac OS X Terminal, it said that, Permission denied. Like as follows:

mv: rename composer.phar to /usr/local/bin/composer: Permission denied

Answer:

Following link led me to the solution like a charm and I'm thankful to that. The thing I just missed was sudo command before the above stated "Move" command line. Now my Move command is as follows:

sudo mv composer.phar /usr/local/bin/composer
Password:

It directly prompts you to authenticate yourself and see if you are authorized. So if you enter a valid password, then the Moving will be done, and you can just check if composer is globally installed, by using the following line.

composer about

I hope this answer helped you to broaden your view and finally resolve your problem.

Cheers!

l = [1,2,3,4,5]
sum = 0
for x in l:
    sum = sum + x

And you can change l for any list you want.

This is way I did it:

%matplotlib inline
import matplotlib.pyplot as plt
plt.rcParams["figure.figsize"] = (12, 9) # (w, h)

You can define your own sizes.

npm install --save bootstrap

afterwards, inside angular-cli.json (inside the project's root folder), find styles and add the bootstrap css file like this:

"styles": [
   "../node_modules/bootstrap/dist/css/bootstrap.min.css",
   "styles.css"
],

UPDATE:
in angular 6+ angular-cli.json was changed to angular.json.

Yes, you can switch on the name...

switch (obj.GetType().Name)
{
    case "TextBox":...
}

Syntax for ngIf/Else

<div *ngIf=”condition; else elseBlock”>Truthy condition</div>
<ng-template #elseBlock>Falsy condition</ng-template>

Using NgIf / Else/ Then explicit syntax

To add then template we just have to bind it to a template explicitly.

<div *ngIf=”condition; then thenBlock else elseBlock”> ... </div> 
<ng-template #thenBlock>Then template</ng-template>
<ng-template #elseBlock>Else template</ng-template>

Observables with NgIf and Async Pipe

You can try to load the child component with history. to do so, pass 'history' through props. Something like that:

  return (
  <div>
    <Login history={this.props.history} />
    <br/>
    <Register/>
  </div>
)

For anyone getting to this thread late, you may want to take a look back at the .Net Base Class Library (BCL). Many people missed the changes between .Net 1.1 and .Net 2.0 when the TraceSource class was introduced (circa 2005).

Using the TraceSource is analagous to other logging frameworks, with granular control of logging, configuration in app.config/web.config, and programmatic access - without the overhead of the enterprise application block.

• .Net BCL Team Blog: Intro to Tracing - Part I (Look at Part II a,b,c as well)

There are also a number of comparisons floating around: "log4net vs TraceSource"

Maybe you want to use CSS "clip-path" (Works with transparency and background)

"clip-path" reference: https://developer.mozilla.org/en-US/docs/Web/CSS/clip-path

Example:

/* With percent */_x000D_
.element-percent {_x000D_

  clip-path: polygon(0 0, 100% 0%, 75% 100%, 0% 100%);_x000D_
}_x000D_
_x000D_
/* With pixel */_x000D_
.element-pixel {_x000D_

It can be detected by storing the previous scrollTop value and comparing the current scrollTop value with it.

JavaScript :

var lastScrollTop = 0;

// element should be replaced with the actual target element on which you have applied scroll, use window in case of no target element.
element.addEventListener("scroll", function(){ // or window.addEventListener("scroll"....
   var st = window.pageYOffset || document.documentElement.scrollTop; // Credits: "https://github.com/qeremy/so/blob/master/so.dom.js#L426"
   if (st > lastScrollTop){
      // downscroll code
   } else {
      // upscroll code
   }
   lastScrollTop = st <= 0 ? 0 : st; // For Mobile or negative scrolling
}, false);

You may want take a look at htmlentities() and html_entity_decode() here

$orig = "I'll \"walk\" the <b>dog</b> now";

$a = htmlentities($orig);

$b = html_entity_decode($a);

echo $a; // I'll &quot;walk&quot; the &lt;b&gt;dog&lt;/b&gt; now

echo $b; // I'll "walk" the <b>dog</b> now

if [ ! -d directory ]; then
  mkdir directory
fi

or

mkdir -p directory

-p ensures creation if directory does not exist

Or simply

add to your element

[ngStyle]="{'color': myVariableColor}"

eg

<mat-icon [ngStyle]="{'color': myVariableColor}">{{ getActivityIcon() }}</mat-icon>

Where color can be defined at another component etc

Catching Exception will catch a RuntimeException

Keep things simple :)

var my_form_obj = {};
my_form_obj.name = "Captain America";
my_form_obj.weapon = "Shield";

Hope this helps!

For .NET 3.5 and lower you could use:

string.Format ("{0:00}:{1:00}:{2:00}", 
               (int)myTimeSpan.TotalHours, 
                    myTimeSpan.Minutes, 
                    myTimeSpan.Seconds);

Code taken from a Jon Skeet answer on bytes

For .NET 4.0 and above, see DoctaJonez answer.

I simply install all the versions of JDK I need and the latest installed becomes default, so I just reinstall the one I want to be default if necessary.

• XQuery Against the xml Data Type
• General XQuery Use Cases
• XQueries Involving Hierarchy

• XQueries Involving Order

• Anything in Michael Rys blog

Update

My recomendation would be to shred the XML into relations and do searches and joins on the resulted relation, in a set oriented fashion, rather than the procedural fashion of searching specific nodes in the XML. Here is a simple XML query that shreds out the nodes and attributes of interest:

select x.value(N'../../../../@stepId', N'int') as StepID
  , x.value(N'../../@id', N'int') as ComponentID
  , x.value(N'@nom',N'nvarchar(100)') as Nom
  , x.value(N'@valeur', N'nvarchar(100)') as Valeur
from @x.nodes(N'/xml/box/components/component/variables/variable') t(x)

However, if you must use an XPath that retrieves exactly the value of interest:

select x.value(N'@valeur', N'nvarchar(100)') as Valeur
from @x.nodes(N'/xml/box[@stepId=sql:variable("@stepID")]/
    components/component[@id = sql:variable("@componentID")]/
       variables/variable[@nom="Enabled"]') t(x)

If the stepID and component ID are columns, not variables, the you should use sql:column() instead of sql:variable in the XPath filters. See Binding Relational Data Inside XML Data.

And finaly if all you need is to check for existance you can use the exist() XML method:

select @x.exist(
  N'/xml/box[@stepId=sql:variable("@stepID")]/
    components/component[@id = sql:variable("@componentID")]/
      variables/variable[@nom="Enabled" and @valeur="Yes"]') 

have you tried something like this:

if [ $# -eq 0 ] || [ $# -gt 1 ] 
then
 echo "$#"
fi

In English:

401

You are potentially allowed access but for some reason on this request you were denied. Such as a bad password? Try again, with the correct request you will get a success response instead.

403

You are not, ever, allowed. Your name is not on the list, you won't ever get in, go away, don't send a re-try request, it will be refused, always. Go away.

You can do this with psutil which is cross-platform:

import psutil
nics = psutil.net_if_addrs()
print [j.address for j in nics[i] for i in nics if i!="lo" and j.family==17]

I imagine that these might possibly be changed with some styling options. But as far as default values go, these are taken from my version of Excel 2010 which should have the defaults.

"Bad" Red Font: 156, 0, 6; Fill: 255, 199, 206

"Good" Green Font: 0, 97, 0; Fill: 198, 239, 206

"Neutral" Yellow Font: 156, 101, 0; Fill: 255, 235, 156

This will surely help you.

int n[] = {4,6,9,1,7};

    for(int i=n.length;i>=0;i--){
        for(int j=0;j<n.length-1;j++){
            if(n[j] > n[j+1]){
                swapNumbers(j,j+1,n);
            }
        }

    }
    printNumbers(n);
}
private static void swapNumbers(int i, int j, int[] array) {

    int temp;
    temp = array[i];
    array[i] = array[j];
    array[j] = temp;
}

private static void printNumbers(int[] input) {

    for (int i = 0; i < input.length; i++) {
        System.out.print(input[i] + ", ");
    }
    System.out.println("\n");
}

None of the above solutions worked for me on Windows 8

But the following command works fine

SHIFT + Q

Recently ran into a problem with this and a Chrome extension that was corrupting a JSON stream when the response header labeled the content-type as 'text/html' apparently extensions can and will use the response header to alter the content prior to further processing by the browser. Changing the content-type fixed the issue.

You want to use DateTimeOffset class.

var date = new DateTimeOffset(2009, 9, 1, 0, 0, 0, 0, new TimeSpan(0L));
var stringDate = date.ToString("u");

sorry I missed your original formatting with the miliseconds

var stringDate = date.ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fff'Z'");

The maximum request size is, by default, 4MB (4096 KB)

This is explained here.

The above article also explains how to fix this issue :)

you can use a workaround, like this:

<input type='date' (keyup)="0" #myDate [(ngModel)]='demoUser.date'/><br>

on your component :

 @Input public date: Date,

Firstly I must say that it's much much simpler if you put your headers in separate files - this is the convention in big data.

Anyway Daniel's answer is pretty good, but it has an inefficiency and a bug, so I'm going to post my own. The inefficiency is that you don't need to check every record to see if it's the header, you just need to check the first record for each partition. The bug is that by using .split(",") you could get an exception thrown or get the wrong column when entries are the empty string and occur at the start or end of the record - to correct that you need to use .split(",", -1). So here is the full code:

val header =
  scala.io.Source.fromInputStream(
    hadoop.fs.FileSystem.get(new java.net.URI(filename), sc.hadoopConfiguration)
    .open(new hadoop.fs.Path(path)))
  .getLines.head

val columnIndex = header.split(",").indexOf(columnName)

sc.textFile(path).mapPartitions(iterator => {
  val head = iterator.next()
  if (head == header) iterator else Iterator(head) ++ iterator
})
.map(_.split(",", -1)(columnIndex))

Final points, consider Parquet if you want to only fish out certain columns. Or at least consider implementing a lazily evaluated split function if you have wide rows.

The easiest way is to hard code the columns yourself to better control the output file:

SELECT 'ColName1', 'ColName2', 'ColName3'
UNION ALL
SELECT ColName1, ColName2, ColName3
    FROM YourTable
    INTO OUTFILE '/path/outfile'

According to Bryan's response you can do this to limit decimals in a query. I convert from km/h to m/s and display it in dygraphs but when I did it in dygraphs it looked weird. Looks fine when doing the calculation in the query instead. This is on postgresql 9.5.1.

select date,(wind_speed/3.6)::numeric(7,1) from readings;

You could also look at the [cxx-rtimers][1] on GitHub, which provide some header-only routines for gathering statistics on the run-time of any code-block where you can create a local variable. Those timers have versions that use std::chrono on C++11, or timers from the Boost library, or standard POSIX timer functions. These timers will report the average, maximum & minimum duration spent within a function, as well as the number of times it is called. They can be used as simply as follows:

#include <rtimers/cxx11.hpp>

void expensiveFunction() {
    static rtimers::cxx11::DefaultTimer timer("expensive");
    auto scopedStartStop = timer.scopedStart();
    // Do something costly...
}

public class GoogleSearch {

    public static void main(String[] args) {

        WebDriver driver=new FirefoxDriver();
        driver.get("http://www.google.com");
        driver.findElement(By.xpath("//input[@type='text']")).sendKeys("Cheese");   
        driver.findElement(By.xpath("//button[@name='btnG']")).click();
        driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS); 
        driver.findElement(By.xpath("(//h3[@class='r']/a)[3]")).click();
        driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS); 
    }
}

If you're looking to remove duplicates based on an id you could do something like this:

var res = [
  {id: 1, content: 'heeey'},
  {id: 2, content: 'woah'}, 
  {id: 1, content:'foo'},
  {id: 1, content: 'heeey'},
];
var uniques = _.map(_.groupBy(res,function(doc){
  return doc.id;
}),function(grouped){
  return grouped[0];
});

//uniques
//[{id: 1, content: 'heeey'},{id: 2, content: 'woah'}]

If you want to have a list of characters (a word), you can use char *word

If you want a list of words (a sentence), you can use char **sentence

If you want a list of sentences (a monologue), you can use char ***monologue

If you want a list of monologues (a biography), you can use char ****biography

If you want a list of biographies (a bio-library), you can use char *****biolibrary

If you want a list of bio-libraries (a ??lol), you can use char ******lol

Output:

Are there situations in which sys.stdout.write() is preferable to print?

I have found that stdout works better than print in a multithreading situation. I use a queue (FIFO) to store the lines to print and I hold all threads before the print line until my print queue is empty. Even so, using print I sometimes lose the final \n on the debug I/O (using the Wing Pro IDE).

When I use std.out with \n in the string, the debug I/O formats correctly and the \n's are accurately displayed.

"Headers already sent" means that your PHP script already sent the HTTP headers, and as such it can't make modifications to them now.

Check that you don't send ANY content before calling session_start. Better yet, just make session_start the first thing you do in your PHP file (so put it at the absolute beginning, before all HTML etc).

If you are working in node.js with lusca try also this:

$.ajax({
url: "http://test.com",
type:"post"
headers: {'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content')}
})

For Xcode 4.1

Still a huge pain. Poor UI design (But my mindset does not seem to match the mindset of software engineers that make 100+ character variable and method names. Enough of my complaining)

I'll modify a previous post for the current version.

1. Close any projects you have open in Xcode (Otherwise the Font window will be inaccessible while a project is open.)
2. Go to XCode > Preferences > Fonts & Color
3. From the 'Theme' box select the theme you want to modify (or select the theme you want to modify and click the "+" button at the bottom of the theme list to clone it first for backup, for there is no undo option)

4. In the source editor box there is a list of types of text that you may set the font for: Plain text Comments Documentation Comments . . .

5. Select any or all items from the source editor list and the name and size of the font for that particular text will show up in the 'Font' window below the 'Source Editor' window. (If you happen to skip highlighting one of these, you will be able to get to the Font Inspector and select new sizes, but will wonder why the changes you make are not being applied!)

6. In the 'Font' window, click the small, almost hidden, and surely poorly design 'T' icon to the right of the font name and size.
7. Voila! In only 14 keystrokes you are able to get the Font inspector window!
8. Your existing font will be preselected in the font inspector. Whatever changes you make now will be applied to the text types you selected in the 'Source Editor' window. e.g. All Fonts > Menlo > Regular > 14
9. Close the windows you opened on this hunt for the holy grail.

Congratulations. Your may now read your code. Wasn't that painless?

just like this :

global $wpdb;
$table_name='lorem_ipsum';
$results = $wpdb->get_results("SELECT * FROM $table_name ORDER BY ID DESC LIMIT 1");
print_r($results[0]->id);

simply your selecting all the rows then order them DESC by id , and displaying only the first

At {virtualenv}/lib/python2.7/site-packages/ (if not using virtualenv then {system_dir}/lib/python2.7/dist-packages/)

• Remove the egg file (e.g. distribute-0.6.34-py2.7.egg)
• If there is any from file easy-install.pth, remove the corresponding line (it should be a path to the source directory or of an egg file).

This looks like a Bootstrap issue...

Currently, here's a workaround : add .col-xs-12 to your responsive image.

Bootply

As far as I understand the question, you can go for:

DateTime dateTime = DateTime.Now;
DateTime dateTimeInMilliseconds = dateTime.AddTicks(-1 * dateTime.Ticks % 10000); 

This will cut off ticks smaller than 1 millisecond.

For SOA system architecture, I use the SOACP Visio stencil. It provides the symbols that are used in Thomas Erl's SOA book series.

I use the Visio Network and Database stencils to model most other requirements.

To do it in LINQ to Entities, you have to use supported methods:

var year = someDate.Year;
var month = ...
var q = from r in Context.Records
        where Microsoft.VisualBasic.DateAndTime.Year(r.SomeDate) == year 
              && // month and day

Ugly, but it works, and it's done on the DB server.

I got a different idea:

First:

pip install python-dotenv

Install the python-dotenv module, which will read local preference for your project environment.

Second:

Add .flaskenv file in your project directory. Add following code:

FLASK_ENV=development

It's done!

With this config for your Flask project, when you run flask run and you will see this output in your terminal:

And when you edit your file, just save the change. You will see auto-reload is there for you:

With more explanation:

Of course you can manually hit export FLASK_ENV=development every time you need. But using different configuration file to handle the actual working environment seems like a better solution, so I strongly recommend this method I use.

They are Synonyms. No Difference At all

Sticky Session / Session Affinity:

Affinity/Stickiness/Contact between user session and, the server to which user request is sent is retained.

Remove NodeJs and npm in your system and reinstall it by following commands

Uninlstallation

sudo apt remove nodejs
sudo apt remove npm

Fresh Installation

sudo apt install nodejs
sudo apt install npm

Configuration optional, in some cases users may face permission errors.

1. user defined directory where npm will install packages

   mkdir ~/.npm-global

2. configure npm

   npm config set prefix '~/.npm-global'

3. add directory to path

   echo 'export PATH=~/.npm-global/bin:$PATH' >> ~/.profile

4. refresh path for the current session

   source ~/.profile

5. cross-check npm and node modules installed successfully in our system

   node -v
npm -v

Installation of npx

sudo npm i -g npx
npx -v

Well-done we are ready to go... now you can easily use npx anywhere in your system.

For me, this error was happening on localhost, but it disappeared when routing it through ngrok and was replaced with a MUCH more helpful error (net::ERR_INCOMPLETE_CHUNKED_ENCODING) that led me here:

https://stackoverflow.com/a/29969400

Basically, the Kestrel server I was using was saying it was chunked output, but not terminating it properly. I double checked it with Fiddler which confirmed the error.

You can use PuDB, a Python debugger with a curses interface to do this. Just add

from pudb import set_interrupt_handler; set_interrupt_handler()

to your code and use Ctrl-C when you want to break. You can continue with c and break again multiple times if you miss it and want to try again.

In this case the CORS problem has been caused by using the wrong source constructor in OpenLayers. ol.source.OSM is intended for accessing the default OpenStreetMap tiles from the web and for that reason defaults to crossOrigin:'anonymous'. If you are using a local source URL you should use the generic ol.source.XYZ constructor which doesn't default the crossOrigin setting (which is why setting crossOrigin:null above happened to work). And it is perfectly legitimate want to use file protocol for maps, for example on an SD card of a mobile device.

If your sole purpose is to convert a 1d array X to a 2d array just do:

X = np.reshape(X,(1, X.size))

This error may ALSO occur in encapsulated SQL statements e.g.

DECLARE @tableName nvarchar(20) SET @tableName = 'GROC'

DECLARE @updtStmt nvarchar(4000)

SET @updtStmt = 'Update tbProductMaster_' +@tableName +' SET department_str = ' + @tableName exec sp_executesql @updtStmt

Only to discover that there are missing quotations to encapsulate the parameter "@tableName" further like the following:

SET @updtStmt = 'Update tbProductMaster_' +@tableName +' SET department_str = ''' + @tableName + ''' '

Thanks

I only need to support HTML5 browsers that support typed arrays (DataView, ArrayBuffer, etc.) I think I took the Joseph Myers code and modified it to support passing in a Uint8Array. I did not catch all the improvements, and there are still probably some char() array artifacts that can be improved on. I needed this for adding to the PouchDB project.

    PouchUtils.Crypto.MD5 = function (uint8Array) {

As everyone else has said, there isn't one in html; however, you could use PUG/Jade. In fact I do this often.

It would look something like this:

select
  - var i = 1
  while i <= 100
    option=i++

This would produce:

You can also use bellow code for pass data using ajax.

var dataString = "album" + title;
$.ajax({  
    type: 'POST',  
    url: 'test.php', 
    data: dataString,
    success: function(response) {
        content.html(response);
    }
});

Check to see if you have previously disabled caching in Chrome when the developer console is open - the setting is under the console, settings icon > General tab: Disable cache (while DevTools is open)

// You can use a state to control wether the component is showing or not
const [show, setShow] = useState(false); // By default won't show

// In return(
{
    show && <ComponentName />
}

/* Use this to toggle the state, this could be in a function in the 
main javascript or could be triggered by an onPress */

show == true ? setShow(false) : setShow(true)

// Example:
const triggerComponent = () => {
    show == true ? setShow(false) : setShow(true)
}

// Or
<SomeComponent onPress={() => {show == true ? setShow(false) : setShow(true)}}/>

It's doable but you have to know that using offset() sets the position of the element relative to the document:

$('.layer1').offset( $('.layer2').offset() );

If you want to convert a python datetime to seconds since epoch you could do it explicitly:

>>> (datetime.datetime(2012,04,01,0,0) - datetime.datetime(1970,1,1)).total_seconds()
1333238400.0

In Python 3.3+ you can use timestamp() instead:

>>> datetime.datetime(2012,4,1,0,0).timestamp()
1333234800.0

Why you should not use datetime.strftime('%s')

Python doesn't actually support %s as an argument to strftime (if you check at http://docs.python.org/library/datetime.html#strftime-and-strptime-behavior it's not in the list), the only reason it's working is because Python is passing the information to your system's strftime, which uses your local timezone.

>>> datetime.datetime(2012,04,01,0,0).strftime('%s')
'1333234800'

Adding autocomplete="new-password" to the password field did the trick. Removed auto filling of both user name and password fields in Chrome.

<input type="password" name="whatever" autocomplete="new-password" />

I know the question has been answered, but in my case I was trying to send the content of a text file to the Slack Webhook api and for some reason the above answer did not work. Anywho, this is what finally did the trick for me:

curl -X POST -H --silent --data-urlencode "payload={\"text\": \"$(cat file.txt | sed "s/\"/'/g")\"}" https://hooks.slack.com/services/XXX

Set the data as a vector and then place in the function.

Expanding on Ender's answer, let's explore our options with the improvements from ES2015.

First off, the problem in the asker's code is the fact that setTimeout is asynchronous while loops are synchronous. So the logical flaw is that they wrote multiple calls to an asynchronous function from a synchronous loop, expecting them to execute synchronously.

function slide() {
    var num = 0;
    for (num=0;num<=10;num++) {
        setTimeout("document.getElementById('container').style.marginLeft='-600px'",3000);
        setTimeout("document.getElementById('container').style.marginLeft='-1200px'",6000);
        setTimeout("document.getElementById('container').style.marginLeft='-1800px'",9000);
        setTimeout("document.getElementById('container').style.marginLeft='0px'",12000);
    }
}

What happens in reality, though, is that...

• The loop "simultaneously" creates 44 async timeouts set to execute 3, 6, 9 and 12 seconds in the future. Asker expected the 44 calls to execute one-after-the-other, but instead, they all execute simultaneously.
• 3 seconds after the loop finishes, container's marginLeft is set to "-600px" 11 times.
• 3 seconds after that, marginLeft is set to "-1200px" 11 times.
• 3 seconds later, "-1800px", 11 times.

And so on.

You could solve this by changing it to:

function setMargin(margin){
    return function(){
        document.querySelector("#container").style.marginLeft = margin;
    };
}

function slide() {
    for (let num = 0; num <= 10; ++num) {
        setTimeout(setMargin("-600px"), + (3000 * (num + 1)));
        setTimeout(setMargin("-1200px"), + (6000 * (num + 1)));
        setTimeout(setMargin("-1800px"), + (9000 * (num + 1)));
        setTimeout(setMargin("0px"), + (12000 * (num + 1)));
    }
}

But that is just a lazy solution that doesn't address the other issues with this implementation. There's a lot of hardcoding and general sloppiness here that ought to be fixed.

As mentioned at the top of this answer, Ender already proposed a solution, but I would like to add on to it, to factor in good practice and modern innovations in the ECMAScript specification.

function format(str, ...args){
    return str.split(/(%)/).map(part => (part == "%") ? (args.shift()) : (part)).join("");
}

function slideLoop(margin, selector){
    const multiplier = -600;
    let contStyle = document.querySelector(selector).style;

    return function(){
        margin = ++margin % 4;
        contStyle.marginLeft = format("%px", margin * multiplier);
    }
}

function slide() {    
    return setInterval(slideLoop(0, "#container"), 3000);
}

Let's go over how this works for the total beginners (note that not all of this is directly related to the question):

format

function format

It's immensely useful to have a printf-like string formatter function in any language. I don't understand why JavaScript doesn't seem to have one.

format(str, ...args)

... is a snazzy feature added in ES6 that lets you do lots of stuff. I believe it's called the spread operator. Syntax: ...identifier or ...array. In a function header, you can use it to specify variable arguments, and it will take every argument at and past the position of said variable argument, and stuff them into an array. You can also call a function with an array like so: args = [1, 2, 3]; i_take_3_args(...args), or you can take an array-like object and transform it into an array: ...document.querySelectorAll("div.someclass").forEach(...). This would not be possible without the spread operator, because querySelectorAll returns an "element list", which isn't a true array.

str.split(/(%)/)

I'm not good at explaining how regex works. JavaScript has two syntaxes for regex. There's the OO way (new RegExp("regex", "gi")) and there's the literal way (/insert regex here/gi). I have a profound hatred for regex because the terse syntax it encourages often does more harm than good (and also because they're extremely non-portable), but there are some instances where regex is helpful, like this one. Normally, if you called split with "%" or /%/, the resulting array would exclude the "%" delimiters from the array. But for the algorithm used here, we need them included. /(%)/ was the first thing I tried and it worked. Lucky guess, I suppose.

.map(...)

map is a functional idiom. You use map to apply a function to a list. Syntax: array.map(function). Function: must return a value and take 1-2 arguments. The first argument will be used to hold each value in the array, while the second will be used to hold the current index in the array. Example: [1,2,3,4,5].map(x => x * x); // returns [1,4,9,16,25]. See also: filter, find, reduce, forEach.

part => ...

This is an alternative form of function. Syntax: argument-list => return-value, e.g. (x, y) => (y * width + x), which is equivalent to function(x, y){return (y * width + x);}.

(part == "%") ? (args.shift()) : (part)

The ?: operator pair is a 3-operand operator called the ternary conditional operator. Syntax: condition ? if-true : if-false, although most people call it the "ternary" operator, since in every language it appears in, it's the only 3-operand operator, every other operator is binary (+, &&, |, =) or unary (++, ..., &, *). Fun fact: some languages (and vendor extensions of languages, like GNU C) implement a two-operand version of the ?: operator with syntax value ?: fallback, which is equivalent to value ? value : fallback, and will use fallback if value evaluates to false. They call it the Elvis Operator.

I should also mention the difference between an expression and an expression-statement, as I realize this may not be intuitive to all programmers. An expression represents a value, and can be assigned to an l-value. An expression can be stuffed inside parentheses and not be considered a syntax error. An expression can itself be an l-value, although most statements are r-values, as the only l-value expressions are those formed from an identifier or (e.g. in C) from a reference/pointer. Functions can return l-values, but don't count on it. Expressions can also be compounded from other, smaller expressions. (1, 2, 3) is an expression formed from three r-value expressions joined by two comma operators. The value of the expression is 3. expression-statements, on the other hand, are statements formed from a single expression. ++somevar is an expression, as it can be used as the r-value in the assignment expression-statement newvar = ++somevar; (the value of the expression newvar = ++somevar, for example, is the value that gets assigned to newvar). ++somevar; is also an expression-statement.

If ternary operators confuse you at all, apply what I just said to the ternary operator: expression ? expression : expression. Ternary operator can form an expression or an expression-statement, so both of these things:

smallest = (a < b) ? (a) : (b);
(valueA < valueB) ? (backup_database()) : (nuke_atlantic_ocean());

are valid uses of the operator. Please don't do the latter, though. That's what if is for. There are cases for this sort of thing in e.g. C preprocessor macros, but we're talking about JavaScript here.

args.shift()

Array.prototype.shift. It's the mirror version of pop, ostensibly inherited from shell languages where you can call shift to move onto the next argument. shift "pops" the first argument out of the array and returns it, mutating the array in the process. The inverse is unshift. Full list:

array.shift()
    [1,2,3] -> [2,3], returns 1
array.unshift(new-element)
    [element, ...] -> [new-element, element, ...]
array.pop()
    [1,2,3] -> [1,2], returns 3
array.push(new-element)
    [..., element] -> [..., element, new-element]

See also: slice, splice

.join("")

Array.prototype.join(string). This function turns an array into a string. Example: [1,2,3].join(", ") -> "1, 2, 3"

slide

return setInterval(slideLoop(0, "#container"), 3000);

First off, we return setInterval's return value so that it may be used later in a call to clearInterval. This is important, because JavaScript won't clean that up by itself. I strongly advise against using setTimeout to make a loop. That is not what setTimeout is designed for, and by doing that, you're reverting to GOTO. Read Dijkstra's 1968 paper, Go To Statement Considered Harmful, to understand why GOTO loops are bad practice.

Second off, you'll notice I did some things differently. The repeating interval is the obvious one. This will run forever until the interval is cleared, and at a delay of 3000ms. The value for the callback is the return value of another function, which I have fed the arguments 0 and "#container". This creates a closure, and you will understand how this works shortly.

slideLoop

function slideLoop(margin, selector)

We take margin (0) and selector ("#container") as arguments. The margin is the initial margin value and the selector is the CSS selector used to find the element we're modifying. Pretty straightforward.

const multiplier = -600;
let contStyle = document.querySelector(selector).style;

I've moved some of the hard coded elements up. Since the margins are in multiples of -600, we have a clearly labeled constant multiplier with that base value.

I've also created a reference to the element's style property via the CSS selector. Since style is an object, this is safe to do, as it will be treated as a reference rather than a copy (read up on Pass By Sharing to understand these semantics).

return function(){
    margin = ++margin % 4;
    contStyle.marginLeft = format("%px", margin * multiplier);
}

Now that we have the scope defined, we return a function that uses said scope. This is called a closure. You should read up on those, too. Understanding JavaScript's admittedly bizarre scoping rules will make the language a lot less painful in the long run.

margin = ++margin % 4;
contStyle.marginLeft = format("%px", margin * multiplier);

Here, we simply increment margin and modulus it by 4. The sequence of values this will produce is 1->2->3->0->1->..., which mimics exactly the behavior from the question without any complicated or hard-coded logic.

Afterwards, we use the format function defined earlier to painlessly set the marginLeft CSS property of the container. It's set to the currnent margin value multiplied by the multiplier, which as you recall was set to -600. -600 -> -1200 -> -1800 -> 0 -> -600 -> ...

There are some important differences between my version and Ender's, which I mentioned in a comment on their answer. I'm gonna go over the reasoning now:

Use document.querySelector(css_selector) instead of document.getElementById(id)

querySelector was added in ES6, if I'm not mistaken. querySelector (returns first found element) and querySelectorAll (returns a list of all found elements) are part of the prototype chain of all DOM elements (not just document), and take a CSS selector, so there are other ways to find an element than just by its ID. You can search by ID (#idname), class (.classname), relationships (div.container div div span, p:nth-child(even)), and attributes (div[name], a[href=https://google.com]), among other things.

Always track setInterval(fn, interval)'s return value so it can later be closed with clearInterval(interval_id)

It's not good design to leave an interval running forever. It's also not good design to write a function that calls itself via setTimeout. That is no different from a GOTO loop. The return value of setInterval should be stored and used to clear the interval when it's no longer needed. Think of it as a form of memory management.

Put the interval's callback into its own formal function for readability and maintainability

Constructs like this

setInterval(function(){
    ...
}, 1000);

Can get clunky pretty easily, especially if you are storing the return value of setInterval. I strongly recommend putting the function outside of the call and giving it a name so that it's clear and self-documenting. This also makes it possible to call a function that returns an anonymous function, in case you're doing stuff with closures (a special type of object that contains the local state surrounding a function).

Array.prototype.forEach is fine.

If state is kept with the callback, the callback should be returned from another function (e.g. slideLoop) to form a closure

You don't want to mush state and callbacks together the way Ender did. This is mess-prone and can become hard to maintain. The state should be in the same function that the anonymous function comes from, so as to clearly separate it from the rest of the world. A better name for slideLoop could be makeSlideLoop, just to make it extra clear.

Use proper whitespace. Logical blocks that do different things should be separated by one empty line

This:

print(some_string);

if(foo && bar)
    baz();

while((some_number = some_fn()) !== SOME_SENTINEL && ++counter < limit)
    ;

quux();

is much easier to read than this:

print(some_string);
if(foo&&bar)baz();
while((some_number=some_fn())!==SOME_SENTINEL&&++counter<limit);
quux();

A lot of beginners do this. Including little 14-year-old me from 2009, and I didn't unlearn that bad habit until probably 2013. Stop trying to crush your code down so small.

Avoid "string" + value + "string" + .... Make a format function or use String.prototype.replace(string/regex, new_string)

Again, this is a matter of readability. This:

format("Hello %! You've visited % times today. Your score is %/% (%%).",
    name, visits, score, maxScore, score/maxScore * 100, "%"
);

is much easier to read than this horrific monstrosity:

"Hello " + name + "! You've visited " + visits + "% times today. " + 
"Your score is " + score + "/" + maxScore + " (" + (score/maxScore * 100) +
"%).",

edit: I'm pleased to point out that I made in error in the above snippet, which in my opinion is a great demonstration of how error-prone this method of string building is.

visits + "% times today"
          ^ whoops

It's a good demonstration because the entire reason I made that error, and didn't notice it for as long as I did(n't), is because the code is bloody hard to read.

Always surround the arguments of your ternary expressions with parens. It aids readability and prevents bugs.

I borrow this rule from the best practices surrounding C preprocessor macros. But I don't really need to explain this one; see for yourself:

let myValue = someValue < maxValue ? someValue * 2 : 0;
let myValue = (someValue < maxValue) ? (someValue * 2) : (0);

I don't care how well you think you understand your language's syntax, the latter will ALWAYS be easier to read than the former, and readability is the the only argument that is necessary. You read thousands of times more code than you write. Don't be a jerk to your future self long-term just so you can pat yourself on the back for being clever in the short term.

1. You are trying to delete a variable allocated on the stack. You can not do this
2. Deleting a pointer does not destruct a pointer actually, just the memory occupied is given back to the OS. You can access it untill the memory is used for another variable, or otherwise manipulated. So it is good practice to set a pointer to NULL (0) after deleting.
3. Deleting a NULL pointer does not delete anything.

Kind of, use the XmlAttribute instead of XmlElement, but it won't look like what you want. It will look like the following:

<SomeModel SomeStringElementName="testData"> 
</SomeModel> 

The only way I can think of to achieve what you want (natively) would be to have properties pointing to objects named SomeStringElementName and SomeInfoElementName where the class contained a single getter named "value". You could take this one step further and use DataContractSerializer so that the wrapper classes can be private. XmlSerializer won't read private properties.

// TODO: make the class generic so that an int or string can be used.
[Serializable]  
public class SerializationClass
{
    public SerializationClass(string value)
    {
        this.Value = value;
    }

    [XmlAttribute("value")]
    public string Value { get; }
}


[Serializable]                     
public class SomeModel                     
{                     
    [XmlIgnore]                     
    public string SomeString { get; set; }                     

    [XmlIgnore]                      
    public int SomeInfo { get; set; }  

    [XmlElement]
    public SerializationClass SomeStringElementName
    {
        get { return new SerializationClass(this.SomeString); }
    }               
}

If you are using JQuery then put the javascript wherever you find it best and use $(document).ready() to ensure that things are loaded properly before executing any functions.

On a side note: I like all my script tags in the <head> section as that seems to be the cleanest place.

class bcolors:
    HEADER = '\033[95m'
    OKBLUE = '\033[94m'
    OKCYAN = '\033[96m'
    OKGREEN = '\033[92m'
    WARNING = '\033[93m'
    FAIL = '\033[91m'
    ENDC = '\033[0m'
    BOLD = '\033[1m'
    UNDERLINE = '\033[4m'

def colour_print(text,colour):
    if colour == 'OKBLUE':
        string = bcolors.OKBLUE + text + bcolors.ENDC
        print(string)
    elif colour == 'HEADER':
        string = bcolors.HEADER + text + bcolors.ENDC
        print(string)
    elif colour == 'OKCYAN':
        string = bcolors.OKCYAN + text + bcolors.ENDC
        print(string)
    elif colour == 'OKGREEN':
        string = bcolors.OKGREEN + text + bcolors.ENDC
        print(string)
    elif colour == 'WARNING':
        string = bcolors.WARNING + text + bcolors.ENDC
        print(string)
    elif colour == 'FAIL':
        string = bcolors.HEADER + text + bcolors.ENDC
        print(string)
    elif colour == 'BOLD':
        string = bcolors.BOLD + text + bcolors.ENDC
        print(string)
    elif colour == 'UNDERLINE':
        string = bcolors.UNDERLINE + text + bcolors.ENDC
        print(string)

just copy the above code. just call them easily

colour_print('Hello world','OKBLUE')
colour_print('easy one','OKCYAN')
colour_print('copy and paste','OKGREEN')
colour_print('done','OKBLUE')

Hope it would help

How about a regex?

function getNum(str) {
  return /[-+]?[0-9]*\.?[0-9]+/.test(str)?parseFloat(str):0;
}

The code below will ignore NaN to allow a calculation of properly entered numbers

function getNum(str) {_x000D_
  return /[-+]?[0-9]*\.?[0-9]+/.test(str)?parseFloat(str):0;_x000D_
}_x000D_
var inputsArray = document.getElementsByTagName('input');_x000D_
_x000D_
function computeTotal() {_x000D_
  var tot = 0;_x000D_
  tot += getNum(inputsArray[0].value);_x000D_
  tot += getNum(inputsArray[1].value);_x000D_
  tot += getNum(inputsArray[2].value);_x000D_
  inputsArray[3].value = tot;_x000D_
}

<input type="text"></input>_x000D_
<input type="text"></input>_x000D_
<input type="text"></input>_x000D_
<input type="text" disabled></input>_x000D_
<button type="button" onclick="computeTotal()">Calculate</button>

Turning off optimization fixes the problem, but it is unnecessary. A safer alternative is to make it illegal for the compiler to optimize out the store by using the volatile type qualifier.

// Assuming pageptr is unsigned char * already...
unsigned char *pageptr = ...;
((unsigned char volatile *)pageptr)[0] = pageptr[0];

The volatile type qualifier instructs the compiler to be strict about memory stores and loads. One purpose of volatile is to let the compiler know that the memory access has side effects, and therefore must be preserved. In this case, the store has the side effect of causing a page fault, and you want the compiler to preserve the page fault.

This way, the surrounding code can still be optimized, and your code is portable to other compilers which don't understand GCC's #pragma or __attribute__ syntax.

You need to adjust three (or four) properties:

• Consumer side:fetch.message.max.bytes - this will determine the largest size of a message that can be fetched by the consumer.
• Broker side: replica.fetch.max.bytes - this will allow for the replicas in the brokers to send messages within the cluster and make sure the messages are replicated correctly. If this is too small, then the message will never be replicated, and therefore, the consumer will never see the message because the message will never be committed (fully replicated).
• Broker side: message.max.bytes - this is the largest size of the message that can be received by the broker from a producer.
• Broker side (per topic): max.message.bytes - this is the largest size of the message the broker will allow to be appended to the topic. This size is validated pre-compression. (Defaults to broker's message.max.bytes.)

I found out the hard way about number 2 - you don't get ANY exceptions, messages, or warnings from Kafka, so be sure to consider this when you are sending large messages.

The best way is to use an And clause in your While statement

Dim count as Integer
count =0
While True And count <= 10
    count=count+1
    Debug.Print(count)
Wend

I had the same error on my Angular6 project. none of those solutions seemed to work out for me. turned out that the problem was due to an element which was specified as dropdown but it didn't have dropdown options in it. take a look at code below:

<span class="nav-link" id="navbarDropdownMenuLink" data-toggle="dropdown"
                          aria-haspopup="true" aria-expanded="false">
                        <i class="material-icons "
                           style="font-size: 2rem">notifications</i>
                        <span class="notification"></span>
                        <p>
                            <span class="d-lg-none d-md-block">Some Actions</span>
                        </p>
                    </span>
                    <div class="dropdown-menu dropdown-menu-left"
                         *ngIf="global.localStorageItem('isInSadHich')"
                         aria-labelledby="navbarDropdownMenuLink">
                                        <a class="dropdown-item" href="#">You have 5 new tasks</a>
                                        <a class="dropdown-item" href="#">You're now friend with Andrew</a>
                                        <a class="dropdown-item" href="#">Another Notification</a>
                                        <a class="dropdown-item" href="#">Another One</a>
                    </div>

removing the code data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" solved the problem.

I myself think that by each click on the first span element, the scope expected to set style for dropdown children which did not existed in the parent span, so it threw error.

show user

simply use the form_validation class of codeigniter:

strip_image_tags($str).

$this->load->library('form_validation');
$this->form_validation->set_rules('nombre_campo', 'label', 'strip_image_tags');

Strings are immutable types. You cannot modify them, only return new string instances.

Because of that, formatting with an instance method makes little sense, as it would have to be called like:

String formatted = "%s: %s".format(key, value);

The original Java authors (and .NET authors) decided that a static method made more sense in this situation, as you are not modifying the target, but instead calling a format method and passing in an input string.

Here is an example of why format() would be dumb as an instance method. In .NET (and probably in Java), Replace() is an instance method.

You can do this:

 "I Like Wine".Replace("Wine","Beer");

However, nothing happens, because strings are immutable. Replace() tries to return a new string, but it is assigned to nothing.

This causes lots of common rookie mistakes like:

inputText.Replace(" ", "%20");

Again, nothing happens, instead you have to do:

inputText = inputText.Replace(" ","%20");

Now, if you understand that strings are immutable, that makes perfect sense. If you don't, then you are just confused. The proper place for Replace() would be where format() is, as a static method of String:

 inputText = String.Replace(inputText, " ", "%20");

Now there is no question as to what's going on.

The real question is, why did the authors of these frameworks decide that one should be an instance method, and the other static? In my opinion, both are more elegantly expressed as static methods.

Regardless of your opinion, the truth is that you are less prone to make a mistake using the static version, and the code is easier to understand (No Hidden Gotchas).

Of course there are some methods that are perfect as instance methods, take String.Length()

int length = "123".Length();

In this situation, it's obvious we are not trying to modify "123", we are just inspecting it, and returning its length. This is a perfect candidate for an instance method.

My simple rules for Instance Methods on Immutable Objects:

• If you need to return a new instance of the same type, use a static method.
• Otherwise, use an instance method.

You can use this to add numbers:

var x = +num1 + +num2;

I know it's a "very long time" since this question was first asked. Just in case, if it helps someone,

Adding relationships is well supported by MS via SQL Server Compact Tool Box (https://sqlcetoolbox.codeplex.com/). Just install it, then you would get the option to connect to the Compact Database using the Server Explorer Window. Right click on the primary table , select "Table Properties". You should have the following window, which contains "Add Relations" tab allowing you to add relations.

This actually worked for me:

private String uri2filename() {

    String ret;
    String scheme = uri.getScheme();

    if (scheme.equals("file")) {
        ret = uri.getLastPathSegment();
    }
    else if (scheme.equals("content")) {
        Cursor cursor = getContentResolver().query(uri, null, null, null, null);
        if (cursor != null && cursor.moveToFirst()) {
            ret = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
        }
   }
   return ret;
}

Before I courageously installed both simultaneously, I had so many questions. If I give python will it go to py3 when i want py2? pip/virtualenv will happen under py2/3?

It seems to be very simple now.

Just blindly install both of them. Make sure you get the right type(x64/x32). While/after installing make sure you add to the path to your environment variables.

[ENVIRONMENT]::SETENVIRONMENTVARIABLE("PATH", "$ENV:PATH;C:\PYTHONx", "USER")

Replace the x in the command above to set the path.

Then go to both the folders.

Navigate to

python3.6/Scripts/

and rename pip to pip3.

If pip3 already exists delete the pip. This will make sure that just pip will run under python2. You can verify by:

pip --version

In case you want to use pip with python3 then just use

pip3 install 

You can similarly do the same to python file and others.

Cheers!

CODE EXPLAINED: When the text box has focus, clear the value. When text box is not focused AND when the box is blank, replace the value.

I hope that works, I have been having the same issue, but then I tried this and it worked for me.

In Rider, this would be Ctrl +Shift+Keypad *, 2

But!, you cannot use the number 2 on keypad, only number 2 on the top row of the keyboard would work.

You cannot mix JS and PHP that way, PHP is rendered before the page is sent to the browser (i.e. before the JS is run)

You can use window.location to change your current page.

$('.entry a:first').click(function() {
    window.location = "http://google.ca";
});
