In order to retrieve the last row of a table for MS SQL database 2005, You can use the following query:

select top 1 column_name from table_name order by column_name desc; 

Note: To get the first row of the table for MS SQL database 2005, You can use the following query:

select top 1 column_name from table_name; 

All rendering is based on OpenGL, so no you can't go over this limit (GL_MAX_TEXTURE_SIZE depends on the device, but the minimum is 2048x2048, so any image lower than 2048x2048 will fit).

With such big images, if you want to zoom in out, and in a mobile, you should setup a system similar to what you see in google maps for example. With the image split in several pieces, and several definitions.

Or you could scale down the image before displaying it (see user1352407's answer on this question).

And also, be careful to which folder you put the image into, Android can automatically scale up images. Have a look at Pilot_51's answer below on this question.

I don't know Sonar, but I suspect it's looking for a private constructor:

private FilePathHelper() {
    // No-op; won't be called
}

Otherwise the Java compiler will provide a public parameterless constructor, which you really don't want.

(You should also make the class final, although other classes wouldn't be able to extend it anyway due to it only having a private constructor.)

Use tiles. It saved my life.

But if you can't, there's the include tag, making it similar to php.

The body tag might not actually do what you need it to, unless you have super simple content. The body tag is used to define the body of a specified element. Take a look at this example:

<jsp:element name="${content.headerName}"   
   xmlns:jsp="http://java.sun.com/JSP/Page">    
   <jsp:attribute name="lang">${content.lang}</jsp:attribute>   
   <jsp:body>${content.body}</jsp:body> 
</jsp:element>

You specify the element name, any attributes that element might have ("lang" in this case), and then the text that goes in it--the body. So if

• content.headerName = h1,
• content.lang = fr, and
• content.body = Heading in French

Then the output would be

<h1 lang="fr">Heading in French</h1>

This is a late entry for folks, but below is my implementation. You will also notice I stubbed-out the ability to change the the KEYs default type: the details about which can be found in the following articles:

• Extending Identity Models and Using Integer Keys Instead of Strings
• Change Primary Key for Users in ASP.NET Identity

NOTES:
It should be noted that you cannot use Guid's for your keys. This is because under the hood they are a Struct, and as such, have no unboxing which would allow their conversion from a generic <TKey> parameter.

Add following code in your click listener function,

NextFragment nextFrag= new NextFragment();
getActivity().getSupportFragmentManager().beginTransaction()
             .replace(R.id.Layout_container, nextFrag, "findThisFragment")
             .addToBackStack(null)
             .commit();

The string "findThisFragment" can be used to find the fragment later, if you need.

An easy way of doing this:

SELECT  ('[' || to_json('Some "text"'::TEXT) || ']')::json ->> 0;

Just convert the json string into a json list

The way I'd do this is:

• In Cell L2, enter the formula ="'"&K2
• Use the fill handle or Ctrl+D to fill it down to the length of Column K's values.
• Select the whole of Column L's values and copy them to the clipboard
• Select the same range in Column K, right-click to select 'Paste Special' and choose 'Values'

Another common solution is adding "Other.." option to the drop down and when selected show text box that is otherwise hidden. Then when submitting the form, assign hidden field value with either the drop down or textbox value and in the server side code check the hidden value.

Example: http://jsfiddle.net/c258Q/

HTML code:

Please select: <form onsubmit="FormSubmit(this);">
<input type="hidden" name="fruit" />
<select name="fruit_ddl" onchange="DropDownChanged(this);">
    <option value="apple">Apple</option>
    <option value="orange">Apricot </option>
    <option value="melon">Peach</option>
    <option value="">Other..</option>
</select> <input type="text" name="fruit_txt" style="display: none;" />
<button type="submit">Submit</button>
</form>

JavaScript:

function DropDownChanged(oDDL) {
    var oTextbox = oDDL.form.elements["fruit_txt"];
    if (oTextbox) {
        oTextbox.style.display = (oDDL.value == "") ? "" : "none";
        if (oDDL.value == "")
            oTextbox.focus();
    }
}

function FormSubmit(oForm) {
    var oHidden = oForm.elements["fruit"];
    var oDDL = oForm.elements["fruit_ddl"];
    var oTextbox = oForm.elements["fruit_txt"];
    if (oHidden && oDDL && oTextbox)
        oHidden.value = (oDDL.value == "") ? oTextbox.value : oDDL.value;
}

And in the server side, read the value of "fruit" from the Request.

Simply query the INFORMATION_SCHEMA:

USE INFORMATION_SCHEMA;
SELECT TABLE_NAME,
       COLUMN_NAME,
       CONSTRAINT_NAME,
       REFERENCED_TABLE_NAME,
       REFERENCED_COLUMN_NAME
FROM KEY_COLUMN_USAGE
WHERE TABLE_SCHEMA = "<your_database_name>" 
      AND TABLE_NAME = "<your_table_name>" 
      AND REFERENCED_COLUMN_NAME IS NOT NULL;

Permissions:

<uses-permission android:name="android.permission.CALL_PHONE" />

Intent:

Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:0377778888"));
startActivity(callIntent);

Write a class A, that contains of an array of class B. Class B should have an id property and a value property. Deserialize the xml to class A. Convert the array in A to the wanted dictionary.

You need to use a group by clause.

SELECT  site_id, MAX(ts) as TIME, count(*) group by site_id

You can't make window.open modal and I strongly recommend you not to go that way. Instead you can use something like jQuery UI's dialog widget.

UPDATE:

You can use load() method:

$("#dialog").load("resource.php").dialog({options});

This way it would be faster but the markup will merge into your main document so any submit will be applied on the main window.

And you can use an IFRAME:

$("#dialog").append($("<iframe></iframe>").attr("src", "resource.php")).dialog({options});

This is slower, but will submit independently.

there is another technique

use

background-size:cover

That is it full set of css is

body { 
    background: url('images/body-bg.jpg') no-repeat center center fixed;
    -moz-background-size: cover;
    -webkit-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
} 

Latest browsers support the default property.

Swift 5: The Codable protocol can be used instead of NSKeyedArchiever.

struct User: Codable {
    let id: String
    let mail: String
    let fullName: String
}

The Pref struct is custom wrapper around the UserDefaults standard object.

struct Pref {
    static let keyUser = "Pref.User"
    static var user: User? {
        get {
            if let data = UserDefaults.standard.object(forKey: keyUser) as? Data {
                do {
                    return try JSONDecoder().decode(User.self, from: data)
                } catch {
                    print("Error while decoding user data")
                }
            }
            return nil
        }
        set {
            if let newValue = newValue {
                do {
                    let data = try JSONEncoder().encode(newValue)
                    UserDefaults.standard.set(data, forKey: keyUser)
                } catch {
                    print("Error while encoding user data")
                }
            } else {
                UserDefaults.standard.removeObject(forKey: keyUser)
            }
        }
    }
}

So you can use it this way:

Pref.user?.name = "John"

if let user = Pref.user {...

Use response.write method in the code-behind.

inline bool IsNan(float f)
{
    const uint32 u = *(uint32*)&f;
    return (u&0x7F800000) == 0x7F800000 && (u&0x7FFFFF);    // Both NaN and qNan.
}

inline bool IsNan(double d)
{
    const uint64 u = *(uint64*)&d;
    return (u&0x7FF0000000000000ULL) == 0x7FF0000000000000ULL && (u&0xFFFFFFFFFFFFFULL);
}

This works if sizeof(int) is 4 and sizeof(long long) is 8.

During run time it is only comparison, castings do not take any time. It just changes comparison flags configuration to check equality.

import matplotlib.pyplot as plt

fig, ax = plt.subplots(2, 2)

To turn off axes for all subplots, do either:

[axi.set_axis_off() for axi in ax.ravel()]

or

map(lambda axi: axi.set_axis_off(), ax.ravel())

Yes, you can use a script like this to generate another script

SET NOCOUNT ON;
DECLARE @NewRole varchar(100), @SourceRole varchar(100);

SELECT @SourceRole = 'Giver', @NewRole = 'Taker';

SELECT
    state_desc + ' ' + permission_name + ' ON ' + OBJECT_NAME(major_id) + ' TO ' + @NewRole
FROM
    sys.database_permissions
WHERE
    grantee_principal_id = DATABASE_PRINCIPAL_ID(@SourceRole) AND
    -- 0 = DB,  1 = object/column, 3 = schema. 1 is normally enough
    class <= 3

To avoid formatting entirely, I think a great solution is to use procedures.

Calling a procedure gives you the result of whatever query you want to put in this procedure. You can actually process multiple queries within a procedure. The call will just return the last query that was called.

MYSQL

DROP PROCEDURE IF EXISTS example;
 DELIMITER //
 CREATE PROCEDURE example()
   BEGIN
   SELECT 2+222+2222+222+222+2222+2222 AS this_is_a_really_long_string_test;
   END //
 DELIMITER;

#calling the procedure gives you the result of whatever query you want to put in this procedure. You can actually process multiple queries within a procedure. The call just returns the last query result
 call example;

Python

sql =('call example;')

Use any of the following as needed:

1.

 App.Current.Shutdown();
OR
 Application.Current.Shutdown();

2.

 App.Current.MainWindow.Close();
OR
 Application.Current.MainWindow.Close();

Above all methods will call closing event of Window class and execution may stop at some point (cause usually applications put dialogues like 'are you sure?' or 'Would you like to save data before closing?', before a window is closed completely)

3. But if you want to terminate the application without any warning immediately. Use below

   Environment.Exit(0);

The com.sun.net.httpserver solution is not portable across JREs. Its better to use the official webservices API in javax.xml.ws to bootstrap a minimal HTTP server...

import java.io._
import javax.xml.ws._
import javax.xml.ws.http._
import javax.xml.transform._
import javax.xml.transform.stream._

@WebServiceProvider
@ServiceMode(value=Service.Mode.PAYLOAD) 
class P extends Provider[Source] {
  def invoke(source: Source) = new StreamSource( new StringReader("<p>Hello There!</p>"));
}

val address = "http://127.0.0.1:8080/"
Endpoint.create(HTTPBinding.HTTP_BINDING, new P()).publish(address)

println("Service running at "+address)
println("Type [CTRL]+[C] to quit!")

Thread.sleep(Long.MaxValue)

EDIT: this actually works! The above code looks like Groovy or something. Here is a translation to Java which I tested:

import java.io.*;
import javax.xml.ws.*;
import javax.xml.ws.http.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;

    public Source invoke(Source request) {
        return  new StreamSource(new StringReader("<p>Hello There!</p>"));
    }

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

        String address = "http://127.0.0.1:8080/";
        Endpoint.create(HTTPBinding.HTTP_BINDING, new Server()).publish(address);

        System.out.println("Service running at " + address);
        System.out.println("Type [CTRL]+[C] to quit!");

        Thread.sleep(Long.MAX_VALUE);
    }
}

You are most likely seeing the unexpected behavior because your text file was created on Windows, so the end of line sequence is \r\n. You can use dos2unix to convert it to a UNIX style text file before running sed or use

sed -r "/^\r?$/d"

to remove blank lines whether or not the carriage return is there.

Strings are "immutable" for good reason: It really saves a lot of headaches, more often than you'd think. It also allows python to be very smart about optimizing their use. If you want to process your string in increments, you can pull out part of it with split() or separate it into two parts using indices:

a = "abc"
a, result = a[:-1], a[-1]

This shows that you're splitting your string in two. If you'll be examining every byte of the string, you can iterate over it (in reverse, if you wish):

for result in reversed(a):
    ...

I should add this seems a little contrived: Your string is more likely to have some separator, and then you'll use split:

ans = "foo,blah,etc."
for a in ans.split(","):
    ...

Firstly, I am not an authority on WebClient vs. HttpClient, specifically. Secondly, from your comments above, it seems to suggest that WebClient is Sync ONLY whereas HttpClient is both.

I did a quick performance test to find how WebClient (Sync calls), HttpClient (Sync and Async) perform. and here are the results.

I see that as a huge difference when thinking for future, i.e. long running processes, responsive GUI, etc. (add to the benefit you suggest by framework 4.5 - which in my actual experience is hugely faster on IIS)

You don't need !important when modifying CSS with jQuery since it modifies the style attribute on the elements in the DOM directly. !important is only needed in stylesheets to disallow a particular style rule from being overridden at a lower level. Modifying style directly is the lowest level you can go, so !important has no meaning.

I struggled with this at first with node.js and async.js is the best library I have found to help you deal with this. If you want to write synchronous code with node, approach is this way.

var async = require('async');

console.log('in main');

doABunchOfThings(function() {
  console.log('back in main');
});

function doABunchOfThings(fnCallback) {
  async.series([
    function(callback) {
      console.log('step 1');
      callback();
    },
    function(callback) {
      setTimeout(callback, 1000);
    },
    function(callback) {
      console.log('step 2');
      callback();
    },
    function(callback) {
      setTimeout(callback, 2000);
    },
    function(callback) {
      console.log('step 3');
      callback();
    },
  ], function(err, results) {
    console.log('done with things');
    fnCallback();
  });
}

this program will ALWAYS produce the following...

in main
step 1
step 2
step 3
done with things
back in main

you can try this exapmple

 START TRANSACTION;
 SET foreign_key_checks = 0;
 ALTER TABLE `job_definers` ADD CONSTRAINT `job_cities_foreign` FOREIGN KEY 
 (`job_cities`) REFERENCES `drop_down_lists`(`id`) ON DELETE CASCADE ON UPDATE CASCADE;
 SET foreign_key_checks = 1;
 COMMIT;

Note : if you are using phpmyadmin just uncheck Enable foreign key checks

as example

hope this soloution fix your problem :)

Or you can make a simple function like this:

// Provided 'c' is only a numeric character
int parseInt (char c) {
    return c - '0';
}

As already pointed out, b += 1 updates b in-place, while a = a + 1 computes a + 1 and then assigns the name a to the result (now a does not refer to a row of A anymore).

To understand the += operator properly though, we need also to understand the concept of mutable versus immutable objects. Consider what happens when we leave out the .reshape:

C = np.arange(12)
for c in C:
    c += 1
print(C)  # [ 0  1  2  3  4  5  6  7  8  9 10 11]

We see that C is not updated, meaning that c += 1 and c = c + 1 are equivalent. This is because now C is a 1D array (C.ndim == 1), and so when iterating over C, each integer element is pulled out and assigned to c.

Now in Python, integers are immutable, meaning that in-place updates are not allowed, effectively transforming c += 1 into c = c + 1, where c now refers to a new integer, not coupled to C in any way. When you loop over the reshaped arrays, whole rows (np.ndarray's) are assigned to b (and a) at a time, which are mutable objects, meaning that you are allowed to stick in new integers at will, which happens when you do a += 1.

It should be mentioned that though + and += are meant to be related as described above (and very much usually are), any type can implement them any way it wants by defining the __add__ and __iadd__ methods, respectively.

I think you want something like

var count = context.MyTable.Count(t => t.MyContainer.ID == '1');

(edited to reflect comments)

Your setup.py file needs setuptools. Some Python packages used to use distutils for distribution, but most now use setuptools, a more complete package. Here is a question about the differences between them.

To install setuptools on Debian:

sudo apt-get install python3-setuptools

For an older version of Python (Python 2.x):

sudo apt-get install python-setuptools

If you want to check if a directory exists, regardless if it's a real directory or a symlink, use this:

ls $DIR
if [ $? != 0 ]; then
        echo "Directory $DIR already exists!"
        exit 1;
fi
echo "Directory $DIR does not exist..."

Explanation: The "ls" command gives an error "ls: /x: No such file or directory" if the directory or symlink does not exist, and also sets the return code, which you can retrieve via "$?", to non-null (normally "1"). Be sure that you check the return code directly after calling "ls".

use underscore as :

_.difference(array1,array2)

Offering a quick answer for people using Ionic. I need to show a tooltip only once so I used the $localStorage to achieve this. This is for playing a track, so when they push play, it shows the tooltip once.

$scope.storage = $localStorage; //connects an object to $localstorage

$scope.storage.hasSeenPopup = "false";  // they haven't seen it


$scope.showPopup = function() {  // popup to tell people to turn sound on

    $scope.data = {}
    // An elaborate, custom popup
    var myPopup = $ionicPopup.show({
        template: '<p class="popuptext">Turn Sound On!</p>',
        cssClass: 'popup'

    });        
    $timeout(function() {
        myPopup.close(); //close the popup after 3 seconds for some reason
    }, 2000);
    $scope.storage.hasSeenPopup = "true"; // they've now seen it

};

$scope.playStream = function(show) {
    PlayerService.play(show);

    $scope.audioObject = audioObject; // this allow for styling the play/pause icons

    if ($scope.storage.hasSeenPopup === "false"){ //only show if they haven't seen it.
        $scope.showPopup();
    }
}

Using @extend is a fine solution, but be aware that the compiled css will break up the class definition. Any classes that extends the same placeholder will be grouped together and the rules that aren't extended in the class will be in a separate definition. If several classes become extended, it can become unruly to look up a selector in the compiled css or the dev tools. Whereas a mixin will duplicate the mixin code and add any additional styles.

You can see the difference between @extend and @mixin in this sassmeister

Your formula is wrong. You probably meant something like:

=IF(AND(NOT(ISBLANK(Q2));NOT(ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Another equivalent:

=IF(NOT(OR(ISBLANK(Q2);ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Or even shorter:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";IF(Q2<=R2;"1";"0"))

OR EVEN SHORTER:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";--(Q2<=R2))

For Blocks lover you can use ALActionBlocks to add action of gestures in block

__weak ALViewController *wSelf = self;
imageView.userInteractionEnabled = YES;

    NSLog(@"pan %@", NSStringFromCGPoint([weakGR locationInView:wSelf.view]));
}];

You can run the utility like grepj package.Class my1.jar my2.war my3.ear

Multiple jar, ear, war files can be provided. For advanced usage use find to provide a list of jars to be searched.

A Protocol?

I found this, it appears to be a local setting for a computer...

http://kb.mozillazine.org/Register_protocol

By entering $PATH on its own at the command prompt, you're trying to run it. This isn't like Windows where you can get your path output by simply typing path.

If you want to see what the path is, simply echo it:

echo $PATH

I want to give a more generalized answer. One that will handle any case when you want to select only the first item in a LEFT JOIN.

You can use a subquery that GROUP_CONCATS what you want (sorted, too!), then just split the GROUP_CONCAT'd result and take only its first item, like so...

LEFT JOIN Person ON Person.id = (
    SELECT SUBSTRING_INDEX(
        GROUP_CONCAT(FirstName ORDER BY FirstName DESC SEPARATOR "_" ), '_', 1)
    ) FROM Person
);

Since we have DESC as our ORDER BY option, this will return a Person id for someone like "Zack". If we wanted someone with the name like "Andy", we would change ORDER BY FirstName DESC to ORDER BY FirstName ASC.

This is nimble, as this places the power of ordering totally within your hands. But, after much testing, it will not scale well in a situation with lots of users and lots of data.

It is, however, useful in running data-intensive reports for admin.

var ref = new Firebase('https://your.firebaseio.com/');

Query query = ref.orderByChild('genre').equalTo('comedy');
query.addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        for (DataSnapshot movieSnapshot : dataSnapshot.getChildren()) {
            Movie movie = dataSnapshot.getValue(Movie.class);
            if (movie.getLead().equals('Jack Nicholson')) {
                console.log(movieSnapshot.getKey());
            }
        }
    }

    @Override
    public void onCancelled(FirebaseError firebaseError) {

    }
});

PySide2 Solution:

Unlike in PyQt5, in PySide2 the QThread.started signal is received/handled on the original thread, not the worker thread! Luckily it still receives all other signals on the worker thread.

In order to match PyQt5's behavior, you have to create the started signal yourself.

Here is an easy solution:

# Use this class instead of QThread
class QThread2(QThread):
    # Use this signal instead of "started"
    started2 = Signal()

    def __init__(self):
        QThread.__init__(self)
        self.started.connect(self.onStarted)

    def onStarted(self):
        self.started2.emit()

Make sure your ~/.aws/credentials file in Unix looks like this:

[MyProfile1]
aws_access_key_id = yourAccessId
aws_secret_access_key = yourSecretKey

[MyProfile2]
aws_access_key_id = yourAccessId
aws_secret_access_key = yourSecretKey

Your Python script should look like this, and it'll work:

from __future__ import print_function
import boto3
import os

os.environ['AWS_PROFILE'] = "MyProfile1"
os.environ['AWS_DEFAULT_REGION'] = "us-east-1"

ec2 = boto3.client('ec2')

# Retrieves all regions/endpoints that work with EC2
response = ec2.describe_regions()
print('Regions:', response['Regions'])

You need that it breaks the outer if statement. Why do you use second else?

IF condition THEN  
    IF condition THEN 
        sequence 1
    // ELSE sequence 4
       // break //?  
    // ENDIF    
ELSE    
    sequence 3    
ENDIF

sequence 4

I had this problem appear out-of-the-blue one day, when a Guzzle(5) script was attempting to connect to a host over SSL. Sure, I could disable the VERIFY option in Guzzle/Curl, but that's clearly not the correct way to go.

I tried everything listed here and in similar threads, then eventually went to terminal with openssl to test against the domain with which I was trying to connect:

openssl s_client -connect example.com:443 

... and received first few lines indicating:

CONNECTED(00000003)
depth=0 CN = example.com
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 CN = example.com
verify error:num=21:unable to verify the first certificate
verify return:1 

... while everything worked fine when trying other destinations (ie: google.com, etc)

This prompted me to contact the domain I had been trying to connect to, and indeed, they had a problem on THEIR END that had crept up. It was resolved and my script went back to working.

So... if you're pulling your hair out, give openssl a shot and see if there's anything up with the response from the location you are attempting to connect. Maybe the issue isn't so 'local' after all sometimes.

This would be the Unicode solution

String s = "A função, Ãugent";
String r = s.replaceAll("\\P{InBasic_Latin}", "");

\p{InBasic_Latin} is the Unicode block that contains all letters in the Unicode range U+0000..U+007F (see regular-expression.info)

\P{InBasic_Latin} is the negated \p{InBasic_Latin}

Use poll to get the first element, and add to add a new last element. That's it, no synchronization or anything else.

The problem could be on this line:

            var selectedText2 = $("#SelectedCountryId:selected").text();

It's looking for the item with id of SelectedCountryId that is selected, where you really want the option that's selected under SelectedCountryId, so try:

$('#SelectedCountryId option:selected').text()

This answers improves on Rashmi Pandit's answer, which is in a way better than the rest because that it seems to completely resolve the exact problem detailed in the question.

The bad part is that is inefficient and not uses the IgnoreCase option consistently.

Inefficient part is because regex can be expensive to construct and execute, and in that answer it could have been constructed just once (calling Regex.IsMatch was just constructing the regex again behind the scene). And Match method could have been called only once and stored in a variable and then linkand name should call Result from that variable.

And the IgnoreCase option was only used in the Match part but not in the Regex.IsMatch part.

I also moved the Regex definition outside the method in order to construct it just once (I think is the sensible approach if we are storing that the assembly with the RegexOptions.Compiled option).

private static Regex hrefRegex = new Regex("<td>\\s*<a\\s*href\\s*=\\s*(?:\"(?<link>[^\"]*)\"|(?<link>\\S+))\\s*>(?<name>.*)\\s*</a>\\s*</td>",  RegexOptions.IgnoreCase | RegexOptions.Compiled);

public static bool TryGetHrefDetails(string htmlTd, out string link, out string name)
{
    var matches = hrefRegex.Match(htmlTd);
    if (matches.Success)
    {
        link = matches.Result("${link}");
        name = matches.Result("${name}");
        return true;
    }
    else
    {
        link = null;
        name = null;
        return false;
    }
}

Here, I have generalized write the code for N tap counts. The code is similarly written for the Enable Developer option in android device phone. Even you can use this to enable features while developer testing the app.

 private Handler tapHandler;
 private Runnable tapRunnable;
 private int mTapCount = 0;
 private int milSecDealy = 2000;

onCreate(){
 ...
tapHandler = new Handler(Looper.getMainLooper());

 }

Call askToExit() on backpress or logout option.

private void askToExit() {
   if (mTapCount >= 2) {
    releaseTapValues();
    /* ========= Exit = TRUE  =========  */
   }

   mTapCount++;
   validateTapCount();
  }


  /* Check with null to avoid create multiple instances of the runnable */
  private void validateTapCount() {
   if (tapRunnable == null) {
    tapRunnable = new Runnable() {
     @Override
     public void run() {
      releaseTapValues();
      /* ========= Exit = FALSE  =========  */
     }
    };
    tapHandler.postDelayed(tapRunnable, milSecDealy);
   }
  }

  private void releaseTapValues() {
   /* Relase the value  */
   if (tapHandler != null) {
    tapHandler.removeCallbacks(tapRunnable);
    tapRunnable = null; /* release the object */
    mTapCount = 0; /* release the value */
   }
  }


  @Override
  protected void onDestroy() {
   super.onDestroy();
   releaseTapValues();
  }

If you are using a GUI and you are still getting the same problem. Just leave the size value empty, the primary key defaults the value to 11, you should be fine with this. Worked with Bitnami phpmyadmin.

Ruby 2.7+

There is now!

Ruby 2.7 is introducing filter_map for this exact purpose. It's idiomatic and performant, and I'd expect it to become the norm very soon.

For example:

numbers = [1, 2, 5, 8, 10, 13]
enum.filter_map { |i| i * 2 if i.even? }
# => [4, 16, 20]

In your case, as the block evaluates to falsey, simply:

items.filter_map { |x| process_x url }

"Ruby 2.7 adds Enumerable#filter_map" is a good read on the subject, with some performance benchmarks against some of the earlier approaches to this problem:

N = 100_000
enum = 1.upto(1_000)
Benchmark.bmbm do |x|
  x.report("select + map")  { N.times { enum.select { |i| i.even? }.map{ |i| i + 1 } } }
  x.report("map + compact") { N.times { enum.map { |i| i + 1 if i.even? }.compact } }
  x.report("filter_map")    { N.times { enum.filter_map { |i| i + 1 if i.even? } } }
end

You can create a putty session, and auto load the script on the server, when starting the session:

putty -load "sessionName" 

At remote command, point to the remote script.

datediff(to_date(String timestamp), to_date(String timestamp))

For example:

SELECT datediff(to_date('2019-08-03'), to_date('2019-08-01')) <= 2;

I suggest using a mutationObserver to do this. It gives you a lot more control over what is going on. It also gives you more details on how the browse interprets all the keystrokes

Here in TypeScript

import * as React from 'react';

export default class Editor extends React.Component {
    private _root: HTMLDivElement; // Ref to the editable div
    private _mutationObserver: MutationObserver; // Modifications observer
    private _innerTextBuffer: string; // Stores the last printed value

    public componentDidMount() {
        this._root.contentEditable = "true";
        this._mutationObserver = new MutationObserver(this.onContentChange);
        this._mutationObserver.observe(this._root, {
            childList: true, // To check for new lines
            subtree: true, // To check for nested elements
            characterData: true // To check for text modifications
        });
    }

    public render() {
        return (
            <div ref={this.onRootRef}>
                Modify the text here ...
            </div>
        );
    }

    private onContentChange: MutationCallback = (mutations: MutationRecord[]) => {
        mutations.forEach(() => {
            // Get the text from the editable div
            // (Use innerHTML to get the HTML)
            const {innerText} = this._root; 

            // Content changed will be triggered several times for one key stroke
            if (!this._innerTextBuffer || this._innerTextBuffer !== innerText) {
                console.log(innerText); // Call this.setState or this.props.onChange here
                this._innerTextBuffer = innerText;
            }
        });
    }

    private onRootRef = (elt: HTMLDivElement) => {
        this._root = elt;
    }
}

Update 2019

The :has() pseudo-selector is propsed in the CSS Selectors 4 spec, and will address this use case once implemented.

To use it, we will write something like:

.foo > .bar:has(> .baz) { /* style here */ }

In a structure like:

<div class="foo">
  <div class="bar">
    <div class="baz">Baz!</div>
  </div>
</div>

This CSS will target the .bar div - because it both has a parent .foo and from its position in the DOM, > .baz resolves to a valid element target.

Original Answer (left for historical purposes) - this portion is no longer accurate

For completeness, I wanted to point out that in the Selectors 4 specification (currently in proposal), this will become possible. Specifically, we will gain Subject Selectors, which will be used in the following format:

!div > span { /* style here */

The ! before the div selector indicates that it is the element to be styled, rather than the span. Unfortunately, no modern browsers (as of the time of this posting) have implemented this as part of their CSS support. There is, however, support via a JavaScript library called Sel, if you want to go down the path of exploration further.

I use this functions

function strright($str, $separator) {
    if (intval($separator)) {
        return substr($str, -$separator);
    } elseif ($separator === 0) {
        return $str;
    } else {
        $strpos = strpos($str, $separator);

        if ($strpos === false) {
            return $str;
        } else {
            return substr($str, -$strpos + 1);
        }
    }
}

function strleft($str, $separator) {
    if (intval($separator)) {
        return substr($str, 0, $separator);
    } elseif ($separator === 0) {
        return $str;
    } else {
        $strpos = strpos($str, $separator);

        if ($strpos === false) {
            return $str;
        } else {
            return substr($str, 0, $strpos);
        }
    }
}

Ran into the same issue and researched this for a few minutes.

I was taught to use Windows 3.1 and DOS, remember those days? Shortly after I worked with Macintosh computers strictly for some time, then began to sway back to Windows after buying a x64-bit machine.

There are actual reasons behind these changes (some would say historical significance), that are necessary for programmers to continue their work.

Most of the changes are mentioned above:

• Program Files vs Program Files (x86)

  In the beginning the 16/86bit files were written on, '86' Intel processors.

• System32 really means System64 (on 64-bit Windows)

  When developers first started working with Windows7, there were several compatibility issues where other applications where stored.

• SysWOW64 really means SysWOW32

  Essentially, in plain english, it means 'Windows on Windows within a 64-bit machine'. Each folder is indicating where the DLLs are located for applications it they wish to use them.

Here are two links with all the basic info you need:

• MSDN File System Redirector

• SysWow64 Explained

Hope this clears things up!

I think it may be a bug in chrome. There was a similar issue long back: See this.

Try in a different browser. I think it should work fine.

Adding the following $cfg helps to narrow down the problem

$cfg['Error_Handler']['display'] = true;
$cfg['Error_Handler']['gather'] = true;

Don't forget to remove those $cfg after done debugging!

From php7 you can use the Spaceship operator:

usort($array, function($a, $b) {
  return new DateTime($a['datetime']) <=> new DateTime($b['datetime']);
});

Maybe you can script/control winscp?

Update: winscp now has a .NET library available as a nuget package that supports SFTP, SCP, and FTPS

As referenced in my answer to Applying rounded corners to paths/polygons, I have written a routine in javascript for generically rounding corners of SVG paths, with examples, here: http://plnkr.co/edit/kGnGGyoOCKil02k04snu.

It will work independently from any stroke effects you may have. To use, include the rounding.js file from the Plnkr and call the function like so:

roundPathCorners(pathString, radius, useFractionalRadius)

The result will be the rounded path.

The results look like this:

No. You can't send headers after they were sent. Try to use hooks in wordpress

(See update at end of answer.)

You can get a NodeList of all of the input elements via getElementsByTagName (DOM specification, MDC, MSDN), then simply loop through it:

var inputs, index;

inputs = document.getElementsByTagName('input');
for (index = 0; index < inputs.length; ++index) {
    // deal with inputs[index] element.
}

There I've used it on the document, which will search the entire document. It also exists on individual elements (DOM specification), allowing you to search only their descendants rather than the whole document, e.g.:

var container, inputs, index;

// Get the container element
container = document.getElementById('container');

// Find its child `input` elements
inputs = container.getElementsByTagName('input');
for (index = 0; index < inputs.length; ++index) {
    // deal with inputs[index] element.
}

...but you've said you don't want to use the parent form, so the first example is more applicable to your question (the second is just there for completeness, in case someone else finding this answer needs to know).

Update: getElementsByTagName is an absolutely fine way to do the above, but what if you want to do something slightly more complicated, like just finding all of the checkboxes instead of all of the input elements?

That's where the useful querySelectorAll comes in: It lets us get a list of elements that match any CSS selector we want. So for our checkboxes example:

var checkboxes = document.querySelectorAll("input[type=checkbox]");

You can also use it at the element level. For instance, if we have a div element in our element variable, we can find all of the spans with the class foo that are inside that div like this:

var fooSpans = element.querySelectorAll("span.foo");

querySelectorAll and its cousin querySelector (which just finds the first matching element instead of giving you a list) are supported by all modern browsers, and also IE8.

You can use the standard isspace() function in ctype.h to achieve this. Simply compare the beginning and end characters of your character array until both ends no longer have spaces.

"spaces" include:

' ' (0x20) space (SPC)

'\t' (0x09) horizontal tab (TAB)

'\n' (0x0a) newline (LF)

'\v' (0x0b) vertical tab (VT)

'\f' (0x0c) feed (FF)

'\r' (0x0d) carriage return (CR)

although there is no function which will do all of the work for you, you will have to roll your own solution to compare each side of the given character array repeatedly until no spaces remain.

Edit:

Since you have access to C++, Boost has a trim implementation waiting for you to make your life a lot easier.

With modern pandas you can just do:

df['new'] = 0

From ?read.table: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.

So, perhaps your data file isn't clean. Being more specific will help the data import:

d = read.table("foobar.txt", 
               sep="\t", 
               col.names=c("id", "name"), 
               fill=FALSE, 
               strip.white=TRUE)

will specify exact columns and fill=FALSE will force a two column data frame.

Ah-ha! The Lodash Changelog says it all...

"Removed _.pluck in favor of _.map with iteratee shorthand"

var objects = [{ 'a': 1 }, { 'a': 2 }];

// in 3.10.1
_.pluck(objects, 'a'); // ? [1, 2]
_.map(objects, 'a'); // ? [1, 2]

// in 4.0.0
_.map(objects, 'a'); // ? [1, 2]

This is how I've managed to load CURL correctly. In my case php was installed from zip package, so I had to add php directory to PATH environment variable.

There are only a few style attributes that can be applied to an <option> element.

This is because this type of element is an example of a "replaced element". They are OS-dependent and are not part of the HTML/browser. It cannot be styled via CSS.

There are replacement plug-ins/libraries that look like a <select> but are actually composed of regular HTML elements that CAN be styled.

Try to add the following:

dataType: "json",
ContentType: "application/json",
data: JSON.stringify({"method":"getStates", "program":"EXPLORE"}),  

For maintainability, I would attach the "blocking" handler on the element itself (in your case, the canvas).

theCanvas.onkeydown = function (e) {
    if (e.key === 'ArrowUp' || e.key === 'ArrowDown') {
        e.view.event.preventDefault();
    }
}

Why not simply do window.event.preventDefault()? MDN states:

window.event is a proprietary Microsoft Internet Explorer property which is only available while a DOM event handler is being called. Its value is the Event object currently being handled.

Because the dot is inside character class (square brackets []).

Take a look at http://www.regular-expressions.info/reference.html, it says (under char class section):

Any character except ^-]\ add that character to the possible matches for the character class.

If your text contains only one individual:

import re

# creation
with open('pers.txt','wb') as g:
    g.write('Dan \n Warrior \n 500 \r\n 1 \r 0 ')

with open('pers.txt','rb') as h:
    print 'exact content of pers.txt before treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
    print '\nrU-display of pers.txt before treatment:\n',h.read()


# treatment
def roplo(file_name,what):
    patR = re.compile('^([^\r\n]+[\r\n]+)[^\r\n]+')
    with open(file_name,'rb+') as f:
        ch = f.read()
        f.seek(0)
        f.write(patR.sub('\\1'+what,ch))
roplo('pers.txt','Mage')


# after treatment
with open('pers.txt','rb') as h:
    print '\nexact content of pers.txt after treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
    print '\nrU-display of pers.txt after treatment:\n',h.read()

If your text contains several individuals:

import re

# creation
with open('pers.txt','wb') as g:
    g.write('Dan \n Warrior \n 500 \r\n 1 \r 0 \n Jim  \n  dragonfly\r300\r2\n10\r\nSomo\ncosmonaut\n490\r\n3\r65')

with open('pers.txt','rb') as h:
    print 'exact content of pers.txt before treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
    print '\nrU-display of pers.txt before treatment:\n',h.read()


# treatment
def ripli(file_name,who,what):
    with open(file_name,'rb+') as f:
        ch = f.read()
        x,y = re.search('^\s*'+who+'\s*[\r\n]+([^\r\n]+)',ch,re.MULTILINE).span(1)
        f.seek(x)
        f.write(what+ch[y:])
ripli('pers.txt','Jim','Wizard')


# after treatment
with open('pers.txt','rb') as h:
    print 'exact content of pers.txt after treatment:\n',repr(h.read())
with open('pers.txt','rU') as h:
    print '\nrU-display of pers.txt after treatment:\n',h.read()

If the “job“ of an individual was of a constant length in the texte, you could change only the portion of texte corresponding to the “job“ the desired individual: that’s the same idea as senderle’s one.

But according to me, better would be to put the characteristics of individuals in a dictionnary recorded in file with cPickle:

from cPickle import dump, load

with open('cards','wb') as f:
    dump({'Dan':['Warrior',500,1,0],'Jim':['dragonfly',300,2,10],'Somo':['cosmonaut',490,3,65]},f)

with open('cards','rb') as g:
    id_cards = load(g)
print 'id_cards before change==',id_cards

id_cards['Jim'][0] = 'Wizard'

with open('cards','w') as h:
    dump(id_cards,h)

with open('cards') as e:
    id_cards = load(e)
print '\nid_cards after change==',id_cards

splice will remove array element(s) by index. Use grep, as in your example, to search and remove.

Switch to Theme... is also an option

This will not only change the max_retries but also enable a backoff strategy which makes requests to all http:// addresses sleep for a period of time before retrying (to a total of 5 times):

import requests
from urllib3.util.retry import Retry
from requests.adapters import HTTPAdapter

s = requests.Session()

retries = Retry(total=5,
                backoff_factor=0.1,
                status_forcelist=[ 500, 502, 503, 504 ])

s.mount('http://', HTTPAdapter(max_retries=retries))

s.get('http://httpstat.us/500')

As per documentation for Retry: if the backoff_factor is 0.1, then sleep() will sleep for [0.1s, 0.2s, 0.4s, ...] between retries. It will also force a retry if the status code returned is 500, 502, 503 or 504.

Various other options to Retry allow for more granular control:

• total – Total number of retries to allow.
• connect – How many connection-related errors to retry on.
• read – How many times to retry on read errors.
• redirect – How many redirects to perform.
• method_whitelist – Set of uppercased HTTP method verbs that we should retry on.
• status_forcelist – A set of HTTP status codes that we should force a retry on.
• backoff_factor – A backoff factor to apply between attempts.
• raise_on_redirect – Whether, if the number of redirects is exhausted, to raise a MaxRetryError, or to return a response with a response code in the 3xx range.
• raise_on_status – Similar meaning to raise_on_redirect: whether we should raise an exception, or return a response, if status falls in status_forcelist range and retries have been exhausted.

NB: raise_on_status is relatively new, and has not made it into a release of urllib3 or requests yet. The raise_on_status keyword argument appears to have made it into the standard library at most in python version 3.6.

To make requests retry on specific HTTP status codes, use status_forcelist. For example, status_forcelist=[503] will retry on status code 503 (service unavailable).

By default, the retry only fires for these conditions:

• Could not get a connection from the pool.
• TimeoutError
• HTTPException raised (from http.client in Python 3 else httplib). This seems to be low-level HTTP exceptions, like URL or protocol not formed correctly.
• SocketError
• ProtocolError

Notice that these are all exceptions that prevent a regular HTTP response from being received. If any regular response is generated, no retry is done. Without using the status_forcelist, even a response with status 500 will not be retried.

To make it behave in a manner which is more intuitive for working with a remote API or web server, I would use the above code snippet, which forces retries on statuses 500, 502, 503 and 504, all of which are not uncommon on the web and (possibly) recoverable given a big enough backoff period.

EDITED: Import Retry class directly from urllib3.

If the body of the arrow function is wrapped in curly braces, it is not implicitly returned. Wrap the object in parentheses. It would look something like this.

p => ({ foo: 'bar' })

By wrapping the body in parens, the function will return { foo: 'bar }.

Hopefully, that solves your problem. If not, I recently wrote an article about Arrow functions which covers it in more detail. I hope you find it useful. Javascript Arrow Functions

Here is a solution using object-scan

// const objectScan = require('object-scan');

const cars = { label: 'Autos', subs: [ { label: 'SUVs', subs: [] }, { label: 'Trucks', subs: [ { label: '2 Wheel Drive', subs: [] }, { label: '4 Wheel Drive', subs: [ { label: 'Ford', subs: [] }, { label: 'Chevrolet', subs: [] } ] } ] }, { label: 'Sedan', subs: [] } ] };

const find = (haystack, label) => objectScan(['**.label'], {
  filterFn: ({ value }) => value === label,
  rtn: 'parent',
  abort: true
})(haystack);

console.log(find(cars, 'Sedan'));
// => { label: 'Sedan', subs: [] }
console.log(find(cars, 'SUVs'));
// => { label: 'SUVs', subs: [] }

.as-console-wrapper {max-height: 100% !important; top: 0}

You can try:

string s1 = Regex.Replace(s, "[^A-Za-z0-9 -]", "");

Where s is your string.

this worked for me ...

On Android 4.2+, uncheck the option Settings > Security > Verify apps and/or Settings > Developer options > Verify apps over USB.

Using multiple threads on CPython won't give you better performance for pure-Python code due to the global interpreter lock (GIL). I suggest using the multiprocessing module instead:

pool = multiprocessing.Pool(4)
out1, out2, out3 = zip(*pool.map(calc_stuff, range(0, 10 * offset, offset)))

Note that this won't work in the interactive interpreter.

To avoid the usual FUD around the GIL: There wouldn't be any advantage to using threads for this example anyway. You want to use processes here, not threads, because they avoid a whole bunch of problems.

You can do this with the apksigner tool that is part of the Android SDK:

apksigner verify --print-certs my_app.apk

You can find apksigner inside the build-tools directory. For example: ~/Library/Android/sdk/build-tools/29.0.1/apksigner

Change hidden field value with checkbox toggle like below...

HTML:

<input type='hidden' value='Unchecked' id="deleteAll" name='anyName'>
<input type="checkbox"  onclick="toggle(this)"/> Delete All

Script:

function toggle(obj) {`var $input = $(obj);
    if ($input.prop('checked')) {

    $('#deleteAll').attr( 'value','Checked');

    } else {

    $('#deleteAll').attr( 'value','Unchecked');

    }

}

Also you can setup extJs writer with encode: true and it will send data regularly (and, hence, you will be able to retrieve data via $_POST and $_GET).

... the values will be sent as part of the request parameters as opposed to a raw post (via docs for encode config of Ext.data.writer.Json)

UPDATE

Also docs say that:

The encode option should only be set to true when a root is defined

So, probably, writer's root config is required.

You can use 100vw / 100vh. CSS3 gives us viewport-relative units. 100vw means 100% of the viewport width. 100vh; 100% of the height.

    <div style="display:flex; justify-content: space-between;background-color: lightyellow; width:100%; height:85vh">
        <div style="width:70%; height: 100%; border: 2px dashed red"></div>
        <div style="width:30%; height: 100%; border: 2px dashed red"></div>
    </div>

Would suggest NOT using INSERT IGNORE as it ignores ALL errors (ie its a sloppy global ignore). Instead, since in your example tag is the unique key, use:

INSERT INTO table_tags (tag) VALUES ('tag_a'),('tab_b'),('tag_c') ON DUPLICATE KEY UPDATE tag=tag;

on duplicate key produces:

Query OK, 0 rows affected (0.07 sec)

While learning about JAR, I came across this thread, but couldn't get enough information for people like me, who have .NET background, so I'm gonna add few points which can help persons like myself with .NET background.

First we need to define similar concept to JAR in .NET which is Assembly and assembly shares a lot in common with Java JAR files.

So, an assembly is the fundamental unit of code packaging in the .NET environment. Assemblies are self contained and typically contain the intermediate code from compiling classes, metadata about the classes, and any other files needed by the packaged code to perform its task. Since assemblies are the fundamental unit of code packaging, several actions related to interacting with types must be done at the assembly level. For instance, granting of security permissions, code deployment, and versioning are done at the assembly level.

Java JAR files perform a similar task in Java with most differences being in the implementation. Assemblies are usually stored as EXEs or DLLs while JAR files are stored in the ZIP file format.

Source of Information -> 5- Assemblies

You can use the map construct to do this. It looks quite ok, but beware that the map line itself will return a list of Nones.

a = [1, 2, 3]
b = [2, 3]

map(lambda x:a.remove(x), b)
a

They have wrapped most stuff need to solve your problem, one of the tests looks like this:

String filename = CSSURLEmbedderTest.class.getResource("folder.png").getPath().replace("%20", " ");
String code = "background: url(folder.png);";

StringWriter writer = new StringWriter();
embedder = new CSSURLEmbedder(new StringReader(code), true);
embedder.embedImages(writer, filename.substring(0, filename.lastIndexOf("/")+1));

String result = writer.toString();
assertEquals("background: url(" + folderDataURI + ");", result);

Use background-position: calc(100% - 20px) center, For pixel perfection calc() is the best solution.

ul {_x000D_
  width: 100px;_x000D_
}_x000D_
ul li {_x000D_
  border: 1px solid orange;_x000D_
  background: url("http://placehold.it/30x15") no-repeat calc(100% - 10px) center;_x000D_
}_x000D_
ul li:hover {_x000D_
  background-position: calc(100% - 20px) center;_x000D_
}

<ul>_x000D_
  <li>Hello</li>_x000D_
  <li>Hello world</li>_x000D_
</ul>

It's the Substring method of String, with the first argument set to 0.

 myString.Substring(0,1);

[The following was added by Almo; see Justin J Stark's comment. —Peter O.]

Warning: If the string's length is less than the number of characters you're taking, you'll get an ArgumentOutOfRangeException.

print "0x%x"%(intNum)

or hex function.

intNum = 123
print hex(intNum)

The solution from Xavier Ho of doubling the width of the stroke and changing the paint-order is brilliant, although only works if the fill is a solid color, with no transparency.

I have developed other approach, more complicated but works for any fill. It also works in ellipses or paths (with the later there are some corner cases with strange behaviour, for example open paths that crosses theirselves, but not much).

The trick is to display the shape in two layers. One without stroke (only fill), and another one only with stroke at double width (transparent fill) and passed through a mask that shows the whole shape, but hides the original shape without stroke.

  <svg width="240" height="240" viewBox="0 0 1024 1024">
  <defs>
    <path id="ld" d="M256,0 L0,512 L384,512 L128,1024 L1024,384 L640,384 L896,0 L256,0 Z"/>
    <mask id="mask">
      <use xlink:href="#ld" stroke="#FFFFFF" stroke-width="160" fill="#FFFFFF"/>
      <use xlink:href="#ld" fill="#000000"/>
    </mask>
  </defs>
  <g>
    <use xlink:href="#ld" fill="#00D2B8"/>
    <use xlink:href="#ld" stroke="#0081C6" stroke-width="160" fill="red" mask="url(#mask)"/>
  </g>

Here's a pretty ggplot2 solution:

library(ggplot2)
library(scales)  # makes pretty labels on the x-axis

breaks=c(0,1,2,3,4,5,25)

ggplot(mydata,aes(x = V3)) + 
  geom_histogram(breaks = log10(breaks)) + 
  scale_x_log10(
    breaks = breaks,
    labels = scales::trans_format("log10", scales::math_format(10^.x))
  )

Note that to set the breaks in geom_histogram, they had to be transformed to work with scale_x_log10

I'm not sure what you're trying to do, but here's something to consider: c(); won't do anything. c is an instance of the class checkbox and not a method to be called. So consider this:

public class FirstWindow extends JFrame {      public FirstWindow() {         checkbox c = new checkbox();         c.yourMethod(yourParameters); // call the method you made in checkbox     } }  public class checkbox extends JFrame {      public checkbox(yourParameters) {          // this is the constructor method used to initialize instance variables     }      public void yourMethod() // doesn't have to be void     {         // put your code here     } } 

Using jQuery from Angular2 is a breeze compared to ng1. If you are using TypeScript you could first reference jQuery typescript definition.

tsd install jquery --save
or
typings install dt~jquery --global --save

TypescriptDefinitions are not required since you could just use any as the type for $ or jQuery

In your angular component you should reference a DOM element from the template using @ViewChild() After the view has been initialized you can use the nativeElement property of this object and pass to jQuery.

Declaring $ (or jQuery) as JQueryStatic will give you a typed reference to jQuery.

import {bootstrap}    from '@angular/platform-browser-dynamic';
import {Component, ViewChild, ElementRef, AfterViewInit} from '@angular/core';
declare var $:JQueryStatic;

@Component({
    selector: 'ng-chosen',
    template: `<select #selectElem>
        <option *ngFor="#item of items" [value]="item" [selected]="item === selectedValue">{{item}} option</option>
        </select>
        <h4> {{selectedValue}}</h4>`
})
export class NgChosenComponent implements AfterViewInit {
    @ViewChild('selectElem') el:ElementRef;
    items = ['First', 'Second', 'Third'];
    selectedValue = 'Second';

    ngAfterViewInit() {
        $(this.el.nativeElement)
            .chosen()
            .on('change', (e, args) => {
                this.selectedValue = args.selected;
            });
    }
}

bootstrap(NgChosenComponent);

This example is available on plunker: http://plnkr.co/edit/Nq9LnK?p=preview

tslint will complain about chosen not being a property on $, to fix this you can add a definition to the JQuery interface in your custom *.d.ts file

interface JQuery {
    chosen(options?:any):JQuery;
}    

This code will split it up for you:

list($whole, $decimal) = explode('.', $your_number);

where $whole is the whole number and $decimal will have the digits after the decimal point.

If you're after readable fail messages, you can do without hamcrest by using the usual assertEquals with an empty list:

assertEquals(new ArrayList<>(0), yourList);

E.g. if you run

assertEquals(new ArrayList<>(0), Arrays.asList("foo", "bar");

you get

java.lang.AssertionError
Expected :[]
Actual   :[foo, bar]

Scott's answer will work for classes of checkboxes. If you want individual checkboxes, you have to be a little sneakier. If you're just doing one box, it's better to do it with IDs. This example does it by specific check boxes and doesn't require jQuery. It's also a nice little example of how you can get those pesky control IDs into your Javascript.

The .ascx:

<script type="text/javascript">

    function checkAgreement(source, args)
    {                
        var elem = document.getElementById('<%= chkAgree.ClientID %>');
        if (elem.checked)
        {
            args.IsValid = true;
        }
        else
        {        
            args.IsValid = false;
        }
    }

    function checkAge(source, args)
    {
        var elem = document.getElementById('<%= chkAge.ClientID %>');
        if (elem.checked)
        {
            args.IsValid = true;
        }
        else
        {
            args.IsValid = false;
        }    
    }

</script>

<asp:CheckBox ID="chkAgree" runat="server" />
<asp:Label AssociatedControlID="chkAgree" runat="server">I agree to the</asp:Label>
<asp:HyperLink ID="lnkTerms" runat="server">Terms & Conditions</asp:HyperLink>
<asp:Label AssociatedControlID="chkAgree" runat="server">.</asp:Label>
<br />

<asp:CustomValidator ID="chkAgreeValidator" runat="server" Display="Dynamic"
    ClientValidationFunction="checkAgreement">
    You must agree to the terms and conditions.
    </asp:CustomValidator>

<asp:CheckBox ID="chkAge" runat="server" />
<asp:Label AssociatedControlID="chkAge" runat="server">I certify that I am at least 18 years of age.</asp:Label>        
<asp:CustomValidator ID="chkAgeValidator" runat="server" Display="Dynamic"
    ClientValidationFunction="checkAge">
    You must be 18 years or older to continue.
    </asp:CustomValidator>

And the codebehind:

Protected Sub chkAgreeValidator_ServerValidate(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ServerValidateEventArgs) _
Handles chkAgreeValidator.ServerValidate
    e.IsValid = chkAgree.Checked
End Sub

Protected Sub chkAgeValidator_ServerValidate(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ServerValidateEventArgs) _
Handles chkAgeValidator.ServerValidate
    e.IsValid = chkAge.Checked
End Sub

All you need is a bit of improved markup. Wrap the second within the first and it will render under.

<div id="wrapper">
    <div id="first">
        Here comes the first content
        <div id="second">I will render below the first content</div>
    </div>
</div>

Demo

Use this class for 30 min

class Session{
    public static function init(){
        ini_set('session.gc_maxlifetime', 1800) ;
        session_start();
    }
    public static function set($key, $val){
        $_SESSION[$key] =$val;
    }
    public static function get($key){
        if(isset($_SESSION[$key])){
            return $_SESSION[$key];
        } else{
            return false;
        }
    }
    public static function checkSession(){
        self::init();
        if(self::get("adminlogin")==false){
            self::destroy();
            header("Location:login.php");
        }
    }
    public static function checkLogin(){
        self::init();
        if(self::get("adminlogin")==true){
            header("Location:index.php");
        }
    }
    public static function destroy(){
        session_destroy();
        header("Location:login.php");
    }
}

or even a very classic old fashion method

IEnumerable<string> collection = new List<string>() { "a", "b", "c" };

for(int i = 0; i < collection.Count(); i++) 
{
    string str1 = collection.ElementAt(i);
    // do your stuff   
}

maybe you would like this method also :-)

Here are several options for getting the "tail" items of an iterable:

Given

n = 9
iterable = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Desired Output

[2, 3, 4, 5, 6, 7, 8, 9, 10]

Code

We get the latter output using any of the following options:

from collections import deque
import itertools

import more_itertools


# A: Slicing
iterable[-n:]


# B: Implement an itertools recipe
def tail(n, iterable):
    """Return an iterator over the last *n* items of *iterable*.

        >>> t = tail(3, 'ABCDEFG')
        >>> list(t)
        ['E', 'F', 'G']

    """
    return iter(deque(iterable, maxlen=n))
list(tail(n, iterable))


# C: Use an implemented recipe, via more_itertools
list(more_itertools.tail(n, iterable))


# D: islice, via itertools
list(itertools.islice(iterable, len(iterable)-n, None))


# E: Negative islice, via more_itertools
list(more_itertools.islice_extended(iterable, -n, None))

Details

• A. Traditional Python slicing is inherent to the language. This option works with sequences such as strings, lists and tuples. However, this kind of slicing does not work on iterators, e.g. iter(iterable).
• B. An itertools recipe. It is generalized to work on any iterable and resolves the iterator issue in the last solution. This recipe must be implemented manually as it is not officially included in the itertools module.
• C. Many recipes, including the latter tool (B), have been conveniently implemented in third party packages. Installing and importing these these libraries obviates manual implementation. One of these libraries is called more_itertools (install via > pip install more-itertools); see more_itertools.tail.
• D. A member of the itertools library. Note, itertools.islice does not support negative slicing.
• E. Another tool is implemented in more_itertools that generalizes itertools.islice to support negative slicing; see more_itertools.islice_extended.

Which one do I use?

It depends. In most cases, slicing (option A, as mentioned in other answers) is most simple option as it built into the language and supports most iterable types. For more general iterators, use any of the remaining options. Note, options C and E require installing a third-party library, which some users may find useful.

For those using Swift 3, the equivalent method for the accepted answer is:

movieArr.sorted { $0.Name < $1.Name }

Honestly, I'm surprised how nobody thought about the git push command:

git push -f . <destination>:<branch>

The dot ( . ) refers the local repository, and you may need the -f option because the destination could be "behind its remote counterpart".

Although this command is used to save your changes in your server, the result is exactly the same as if moving the remote branch (<branch>) to the same commit as the local branch (<destination>)

You need to use <> operator:

while (<>) {
    print $_; # or simply "print;"
}

Which can be compacted to:

print while (<>);

Arbitrary file:

open F, "<file.txt" or die $!;
while (<F>) {
    print $_;
}
close F;

step into will dig into method calls
step over will just execute the line and go to the next one

Abstraction is related with methods where implementation detail is not known which is a kind of implementation hiding.
Encapsulation is related with instance variable binding with method, a kind of data hiding.

Eric Niebler is working on a range-proposal and some of the examples show how to remove certain elements. Removing 8. Does create a new vector.

#include <iostream>
#include <range/v3/all.hpp>

int main(int argc, char const *argv[])
{
    std::vector<int> vi{2,4,6,8,10};
    for (auto& i : vi) {
        std::cout << i << std::endl;
    }
    std::cout << "-----" << std::endl;
    std::vector<int> vim = vi | ranges::view::remove_if([](int i){return i == 8;});
    for (auto& i : vim) {
        std::cout << i << std::endl;
    }
    return 0;
}

outputs

What kind of problem do you get with jregex? It worked well for me under java5 and java6.

Jregex does the job well (even if the last version is from 2002), unless you want to wait for javaSE 7.

Set counter to zero. Each time you draw a frame increment the counter. After each second print the counter. lather, rinse, repeat. If yo want extra credit, keep a running counter and divide by the total number of seconds for a running average.

One way would be to use read -s option .. this way the password characters are not echoed back to the screen. I wrote a small script for some use cases and you can see it in my blog: http://www.datauniv.com/blogs/2013/02/21/a-quick-little-expect-script/

Or the minified version of the file...

This is some really cool stuff! I needed pretty much the same, but with horizontal gradient from white to transparent. And it is working just fine! Here ist my code:

.gradient{
        /* webkit example */
        background-image: -webkit-gradient(
          linear, right top, left top, from(rgba(255, 255, 255, 1.0)),
          to(rgba(255, 255, 255, 0))
        );

        /* mozilla example - FF3.6+ */
        background-image: -moz-linear-gradient(
          right center,
          rgba(255, 255, 255, 1.0) 20%, rgba(255, 255, 255, 0) 95%
        );

        /* IE 5.5 - 7 */
        filter: progid:DXImageTransform.Microsoft.gradient(
          gradientType=1, startColor=0, endColorStr=#FFFFFF
        );

        /* IE8 uses -ms-filter for whatever reason... */
        -ms-filter: progid:DXImageTransform.Microsoft.gradient(
          gradientType=1, startColor=0, endColoStr=#FFFFFF
        );
    }

Something like this should work

var text = $('#toptitle').text();
if (text == 'Profil'){
    $('#toptitle').text('New Word');
}

@kit's answer is okay, but remember to add ROUTER_PROVIDERS to providers in the component. Then you can redirect to another page within ngOnInit method:

import {Component, OnInit} from 'angular2/core';
import {Router, ROUTER_PROVIDERS} from 'angular2/router'

@Component({
    selector: 'loginForm',
    templateUrl: 'login.html',
    providers: [ROUTER_PROVIDERS]
})

export class LoginComponent implements OnInit {

    constructor(private router: Router) { }

    ngOnInit() {
        this.router.navigate(['./SomewhereElse']);
    }

}

I think you want:

items.GroupBy(item => item.Order.Customer)
     .Select(group => new { Customer = group.Key, Items = group.ToList() })
     .ToList() 

If you want to continue use the overload of GroupBy you are currently using, you can do:

items.GroupBy(item => item.Order.Customer, 
              (key, group) =>  new { Customer = key, Items = group.ToList() })
     .ToList() 

...but I personally find that less clear.

My solution that would work on Chrome, Firefox, IE9, IE10 (Change the degrees as per your requirement):

.rotate-text {
  -webkit-transform: rotate(270deg);
  -moz-transform: rotate(270deg);
  -ms-transform: rotate(270deg);
  -o-transform: rotate(270deg);
  transform: rotate(270deg);
  filter: none; /*Mandatory for IE9 to show the vertical text correctly*/      
}

I had the same problem, and "export LC_ALL=c" didn't work for me.

Try export LC_ALL="en_US.UTF-8" (it will work).

Just in case anyone is having the same problem... I was getting this error, and it turned out to be my <Application.Resources> in my App.xaml file. I had a resource outside my resource dictionary tags, and that caused this error.

Just to note that nginx has now support for Websockets on the release 1.3.13. Example of use:

location /websocket/ {

    proxy_pass ?http://backend_host;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_read_timeout 86400;

}

You can also check the nginx changelog and the WebSocket proxying documentation.

Sending raw POST requests can be sometimes more convenient. Below you can see post.js original example from PhantomJS

// Example using HTTP POST operation

var page = require('webpage').create(),
    server = 'http://posttestserver.com/post.php?dump',
    data = 'universe=expanding&answer=42';

page.open(server, 'post', data, function (status) {
    if (status !== 'success') {
        console.log('Unable to post!');
    } else {
        console.log(page.content);
    }
    phantom.exit();
});

I recently encountered this issue while mocking a function in a Kotlin data class. For some unknown reason one of my test runs ended up in a frozen state. When I ran the tests again some of my tests that had previously passed started to fail with the WrongTypeOfReturnValue exception.

I ensured I was using org.mockito:mockito-inline to avoid the issues with final classes (mentioned by Arvidaa), but the problem remained. What solved it for me was to kill the process and restart Android Studio. This terminated my frozen test run and the following test runs passed without issues.

I had same problem since updated platfrom-tool to version 24 and not sure for root cause...(current adb version is 1.0.36)

If all you need is mousedown, you may be able to make do with the document.elementFromPoint method, by:

1. removing the top layer on mousedown,
2. passing the x and y coordinates from the event to the document.elementFromPoint method to get the element underneath, and then
3. restoring the top layer.

The problem you are most likely having is that there is a link somewhere in the page to an anchor that does not exist. For instance, let's say you have the following:

<a href="#examples">Skip to examples</a>

There has to be an element in the page with that id, example:

<div id="examples">Here are the examples</div>

So make sure that each one of the links are matched inside the page with it's corresponding anchor.

Create a .c file containing just the line:

_MSC_VER

or

CompilerVersion=_MSC_VER

then pre-process with

cl /nologo /EP <filename>.c

It is easy to parse the output.

There is an article on javaworld.com that explains the difference => Which ClassLoader should you use

(1)

Thread context classloaders provide a back door around the classloading delegation scheme.

Take JNDI for instance: its guts are implemented by bootstrap classes in rt.jar (starting with J2SE 1.3), but these core JNDI classes may load JNDI providers implemented by independent vendors and potentially deployed in the application's -classpath. This scenario calls for a parent classloader (the primordial one in this case) to load a class visible to one of its child classloaders (the system one, for example). Normal J2SE delegation does not work, and the workaround is to make the core JNDI classes use thread context loaders, thus effectively "tunneling" through the classloader hierarchy in the direction opposite to the proper delegation.

(2) from the same source:

This confusion will probably stay with Java for some time. Take any J2SE API with dynamic resource loading of any kind and try to guess which loading strategy it uses. Here is a sampling:

• JNDI uses context classloaders
• Class.getResource() and Class.forName() use the current classloader
• JAXP uses context classloaders (as of J2SE 1.4)
• java.util.ResourceBundle uses the caller's current classloader
• URL protocol handlers specified via java.protocol.handler.pkgs system property are looked up in the bootstrap and system classloaders only
• Java Serialization API uses the caller's current classloader by default

The proper way is mvn package if you did things correctly for the core part of your build then there should be no need to install your packages in the local repository.

In addition if you use Travis you can "cache" your dependencies because it will not touch your $HOME.m2/repository if you use package for your own project.

In practicality if you even attempt to do a mvn site you usually need to do a mvn install before. There's just too many bugs with either site or it's numerous poorly maintained plugins.

Generally, package names in the site-packages folder are intended to be imported using the exact name of the module or subfolder.

If my site-packages folder has a subfolder named "foobar", I would import that package by typing import foobar.

One solution might be to rename site-packages\wx-2.8-msw-unicode to site-packages\wx.

Or you could add C:\Python27\Lib\site-packages\wx-2.8-msw-unicode to your PYTHONPATH environment variable.

I am using the following:

set iso_date=%date:~6,4%-%date:~3,2%-%date:~0,2%

Or in combination with a logfile name 'MyLogFileName':

set log_file=%date:~6,4%-%date:~3,2%-%date:~0,2%-MyLogFileName

Simply cereate a dummy repo, open a new issue and use @xxxxx to notify the affected user.

If user has notification via e-mail enabled he will get an e-mail, if not he will notice on next login.

No need to search for e-mail adress in commits or activity stream and privacy is respected.

The only way I could get this to work is to pass the JSON as a string and then deserialise it using JavaScriptSerializer.Deserialize<T>(string input), which is pretty strange if that's the default deserializer for MVC 4.

My model has nested lists of objects and the best I could get using JSON data is the uppermost list to have the correct number of items in it, but all the fields in the items were null.

This kind of thing should not be so hard.

    $.ajax({
        type: 'POST',
        url: '/Agri/Map/SaveSelfValuation',
        data: { json: JSON.stringify(model) },
        dataType: 'text',
        success: function (data) {

    [HttpPost]
    public JsonResult DoSomething(string json)
    {
        var model = new JavaScriptSerializer().Deserialize<Valuation>(json);

$model=User::where('id',$id)->delete();

MySQL has a short description of their more or less strict rules:

Put your code in between this div if you are using bootstrap:

  <div class="text-center ">
  <i class="fa fa-twitter" style="font-size:36px "></i>
  <i class="fa fa-pinterest" style="font-size:36px"></i>
  <i class="fa fa-dribbble" style="font-size:36px"></i>
  <i class="fa fa-instagram" style="font-size:36px"></i>

Try using SCP on Windows to transfer files, you can download SCP from Putty's website. Then try running:

pscp.exe filename.extension [email protected]:directory/subdirectory

There is a full length guide here.

It looks like this is the case when Chrome is not compliant with WebSocket standard. When the server initiates close and sends close frame to a client, Chrome considers this to be an error and reports it to JS side with code 1006 and no reason message. In my tests, Chrome never responds to server-initiated close frames (close code 1000) suggesting that code 1006 probably means that Chrome is reporting its own internal error.

P.S. Firefox v57.00 handles this case properly and successfully delivers server's reason message to JS side.

This is iteration using block approach:

    NSDictionary *dict = @{@"key1":@1, @"key2":@2, @"key3":@3};

    [dict enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
        NSLog(@"%@->%@",key,obj);
        // Set stop to YES when you wanted to break the iteration.
    }];

With autocompletion is very fast to set, and you do not have to worry about writing iteration envelope.

Case 1 : Yes, this works fine.

Case 2 : This will fail with the error ORA-01441 : cannot decrease column length because some value is too big.

The CSS :first-child selector allows you to target an element that is the first child element within its parent.

element:first-child { style_properties }
table:first-child { style_properties }

Interesting. I have a few questions which may point out the problem.

1/ Are you untarring on the same platform as you're tarring on? They may be different versions of tar (e.g., GNU and old-unix)? If they're different, can you untar on the same box you tarred on?

2/ What happens when you simply gunzip myarchive.tar.gz? Does that work? Maybe your file is being corrupted/truncated. I'm assuming you would notice if the compression generated errors, yes?

Based on the GNU tar source, it will only print that message if find_next_block() returns 0 prematurely which is usually caused by truncated archive.

To actually cover your pattern, i.e, valid file names according to your rules, I think that you need a little more. Note this doesn't match legal file names from a system perspective. That would be system dependent and more liberal in what it accepts. This is intended to match your acceptable patterns.

^([a-zA-Z0-9]+[_-])*[a-zA-Z0-9]+\.[a-zA-Z0-9]+$

Explanation:

• ^ Match the start of a string. This (plus the end match) forces the string to conform to the exact expression, not merely contain a substring matching the expression.
• ([a-zA-Z0-9]+[_-])* Zero or more occurrences of one or more letters or numbers followed by an underscore or dash. This causes all names that contain a dash or underscore to have letters or numbers between them.
• [a-zA-Z0-9]+ One or more letters or numbers. This covers all names that do not contain an underscore or a dash.
• \. A literal period (dot). Forces the file name to have an extension and, by exclusion from the rest of the pattern, only allow the period to be used between the name and the extension. If you want more than one extension that could be handled as well using the same technique as for the dash/underscore, just at the end.
• [a-zA-Z0-9]+ One or more letters or numbers. The extension must be at least one character long and must contain only letters and numbers. This is typical, but if you wanted allow underscores, that could be addressed as well. You could also supply a length range {2,3} instead of the one or more + matcher, if that were more appropriate.
• $ Match the end of the string. See the starting character.

I have tried the following command and they work well.

bzip2 -t file.bz2
gunzip -t file.gz

However, we can found these two command are time-consuming. Maybe we need some more quick way to determine the intact of the compress files.

For those who wants to have readable timestamp in format of, yyyymmddHHMMSS

Usage example: a backup file extension. /my/path/my.file.js.20190220

Here is a simple example of how to use imageEdgeInsets This will make a 30x30 button with a hittable area 10 pixels bigger all the way around (50x50)

    var expandHittableAreaAmt : CGFloat = 10
    var buttonWidth : CGFloat = 30
    var button = UIButton.buttonWithType(UIButtonType.Custom) as UIButton
    button.frame = CGRectMake(0, 0, buttonWidth+expandHittableAreaAmt, buttonWidth+expandHittableAreaAmt)
    button.imageEdgeInsets = UIEdgeInsetsMake(expandHittableAreaAmt, expandHittableAreaAmt, expandHittableAreaAmt, expandHittableAreaAmt)
    button.setImage(UIImage(named: "buttonImage"), forState: .Normal)
    button.addTarget(self, action: "didTouchButton:", forControlEvents:.TouchUpInside)

"The way a FK works is it cannot have a value in that column that is not also in the primary key column of the referenced table."

What is missing from this answer is simply;

You must build the table containing the Primary Key first.

Another way to say it is;

You must Insert Data into the parent table, containing the Primary Key, before attempting to insert data into the child table containing the Foreign Key.

In short, many of the tutorials seem to be glazing over this fact so that if you were to try on your own and didn't realize there was an order of operations, then you would get this error. Naturally after adding the primary key data, your foreign key data in the child table must conform to the primary key field in the parent table, otherwise, you will still get this error.

If anyone read down this far. I hope this helped make the checked answer more clear. I know there are some of you who may feel that this sort of thing is pretty straight-forward and that opening a book would have answered this question before it was posted, but the truth is that not everyone learns in the same way.

I would say store them as an big integer, as a phone number itself is just a number. This also gives you more flexibility in how you present your phone numbers later, depending on what situation you are in.

I have found it best to add viewBox and preserveAspectRatio attributes to my SVGs. The viewbox should describe the full width and height of the SVG in the form 0 0 w h:

<svg preserveAspectRatio="xMidYMid meet" viewBox="0 0 700 550"></svg>

Not the best answer, but it's an option anyway:

Comment the given line in the web.config.

In case you need to find documents which contain NULL elements inside an array of sub-documents, I've found this query which works pretty well:

db.collection.find({"keyWithArray":{$elemMatch:{"$in":[null], "$exists":true}}})

This query is taken from this post: MongoDb query array with null values

It was a great find and it works much better than my own initial and wrong version (which turned out to work fine only for arrays with one element):

.find({
    'MyArrayOfSubDocuments': { $not: { $size: 0 } },
    'MyArrayOfSubDocuments._id': { $exists: false }
})

Another veneration of find_elements_by_xpath(".//*") is:

from selenium.webdriver.common.by import By


find_elements(By.XPATH, ".//*")

iisexpress program is responsible for that.

Type syso and ctrl + space for System.out.println()

Had the same error when I had @Order annotation on a filter class. Even thou I added the filter through the HttpSecurity chain.

Removed the @Order and it worked.

You could try adding a custom script, say myenv_vars.sh in /etc/profile.d.

cd /etc/profile.d
sudo touch myenv_vars.sh
sudo gedit myenv_vars.sh

Add this to the empty file, and save it.

export LD_LIBRARY_PATH=/usr/local/lib

AStyle can be customized in great detail for C++ and Java (and others too)

This is a source code formatting tool.

clang-format is a powerful command line tool bundled with the clang compiler which handles even the most obscure language constructs in a coherent way.

It can be integrated with Visual Studio, Emacs, Vim (and others) and can format just the selected lines (or with git/svn to format some diff).

It can be configured with a variety of options listed here.

When using config files (named .clang-format) styles can be per directory - the closest such file in parent directories shall be used for a particular file.

Styles can be inherited from a preset (say LLVM or Google) and can later override different options

It is used by Google and others and is production ready.

Also look at the project UniversalIndentGUI. You can experiment with several indenters using it: AStyle, Uncrustify, GreatCode, ... and select the best for you. Any of them can be run later from a command line.

Uncrustify has a lot of configurable options. You'll probably need Universal Indent GUI (in Konstantin's reply) as well to configure it.

You need to pass an array of element to jsx. The problem is that forEach does not return anything (i.e it returns undefined). So it's better to use map because map returns an array:

class QuestionSet extends Component {
render(){ 
    <div className="container">
       <h1>{this.props.question.text}</h1>
       {this.props.question.answers.map((answer, i) => {     
           console.log("Entered");                 
           // Return the element. Also pass key     
           return (<Answer key={answer} answer={answer} />) 
        })}
}

export default QuestionSet;

You are not allowed to implement network operations on the UI thread on Android. You will have to use AsyncTask class to perform network related operations like sending API request, downloading image from a URL, etc. and using callback methods of AsyncTask, you can get you result in onPostExecute menthod and you will be in the UI thread and you can populate UI with data from web service or something like that.

Example: Suppose you want to download image from an URL: https://www.samplewebsite.com/sampleimage.jpg

Solution using AsyncTask: are respectively.

    public class MyDownloader extends AsyncTask<String,Void,Bitmap>
    {
        @Override
        protected void onPreExecute() {
            // Show progress dialog
            super.onPreExecute();
        }

        @Override
        protected void onPostExecute(Bitmap bitmap) {
            //Populate Ui
            super.onPostExecute(bitmap);
        }

        @Override
        protected Bitmap doInBackground(String... params) {
            // Open URL connection read bitmaps and return form here
            return result;
        }

        @Override
        protected void onProgressUpdate(Void... values) {
            // Show progress update
            super.onProgressUpdate(values);
        }


    }
}

Note: Do not forget to add the Internet permission in the Android manifest file. It will work like a charm. :)

Notice the cool thing in S.Lott's comment - you can also call functions with *mylist and **mydict to unpack positional and keyword arguments:

def foo(a, b, c, d):
  print a, b, c, d

l = [0, 1]
d = {"d":3, "c":2}

foo(*l, **d)

Will print: 0 1 2 3

In VBA (and VB.NET) the line terminator (carriage return) is used to signal the end of a statement. To break long statements into several lines, you need to

Use the line-continuation character, which is an underscore (_), at the point at which you want the line to break. The underscore must be immediately preceded by a space and immediately followed by a line terminator (carriage return).

(From How to: Break and Combine Statements in Code)

In other words: Whenever the interpreter encounters the sequence <space>_<line terminator>, it is ignored and parsing continues on the next line. Note, that even when ignored, the line continuation still acts as a token separator, so it cannot be used in the middle of a variable name, for example. You also cannot continue a comment by using a line-continuation character.

To break the statement in your question into several lines you could do the following:

U_matrix(i, j, n + 1) = _
     k * b_xyt(xi, yi, tn) / (4 * hx * hy) * U_matrix(i + 1, j + 1, n) + _
     (k * (a_xyt(xi, yi, tn) / hx ^ 2 + d_xyt(xi, yi, tn) / (2 * hx)))

(Leading whitespaces are ignored.)

It looks like you are not providing a value for the primary key field DB_ID. If that is a primary key, you must provide a unique value for that column. The only way not to provide it would be to create a database trigger that, on insert, would provide a value, most likely derived from a sequence.

If this is a restoration from another database and there is a sequence on this new instance, it might be trying to reuse a value. If the old data had unique keys from 1 - 1000 and your current sequence is at 500, it would be generating values that already exist. If a sequence does exist for this table and it is trying to use it, you would need to reconcile the values in your table with the current value of the sequence.

You can use SEQUENCE_NAME.CURRVAL to see the current value of the sequence (if it exists of course)

try this:

import net.sf.json.JSONObject;
import net.sf.json.JSONSerializer;
import org.apache.commons.io.IOUtils; 

    public class JsonParsing {

        public static void main(String[] args) throws Exception {
            InputStream is = 
                    JsonParsing.class.getResourceAsStream( "sample-json.txt");
            String jsonTxt = IOUtils.toString( is );

            JSONObject json = (JSONObject) JSONSerializer.toJSON( jsonTxt );        
            double coolness = json.getDouble( "coolness" );
            int altitude = json.getInt( "altitude" );
            JSONObject pilot = json.getJSONObject("pilot");
            String firstName = pilot.getString("firstName");
            String lastName = pilot.getString("lastName");

            System.out.println( "Coolness: " + coolness );
            System.out.println( "Altitude: " + altitude );
            System.out.println( "Pilot: " + lastName );
        }
    }

and this is your sample-json.txt , should be in json format

{
 'foo':'bar',
 'coolness':2.0,
 'altitude':39000,
 'pilot':
     {
         'firstName':'Buzz',
         'lastName':'Aldrin'
     },
 'mission':'apollo 11'
}

Let's say a=[1,2,3] and you want it to be [1,2,3,1].

You may use the built-in append function

np.append(a,1)

Here 1 is an int, it may be a string and it may or may not belong to the elements in the array. Prints: [1,2,3,1]

Verification, do not forget the to_s

 def nottolonng?(value)
   if value.to_s.length <=8
     return true
   else
     return false
   end
  end

Just use CSS to increase it's height:

<input type="text" style="height:30px;" name="item" align="left" />

Or, often times, you want to increase it's height by using padding instead of specifying an exact height:

<input type="text" style="padding: 5px;" name="item" align="left" />

I'm pretty sure you can do explicit casting here.

foo f = (foo)value;

So long as you say the enum inherits(?) from int, which you have.

enum foo : int

EDIT Yes it turns out that by default, an enums underlying type is int. You can however use any integral type except char.

You can also cast from a value that's not in the enum, producing an invalid enum. I suspect this works by just changing the type of the reference and not actually changing the value in memory.

enum (C# Reference)
Enumeration Types (C# Programming Guide)

The final outcome of the conversion is that the number of elements in the final array is same as that of the initial array or data frame.

-1 corresponds to the unknown count of the row or column. We can think of it as x(unknown). x is obtained by dividing the number of elements in the original array by the other value of the ordered pair with -1.

Examples:

12 elements with reshape(-1,1) corresponds to an array with x=12/1=12 rows and 1 column.

12 elements with reshape(1,-1) corresponds to an array with 1 row and x=12/1=12 columns.

Compile with O3, The compiler performs optimization well.

q = x / y;
if (x % y)  ++q;

${#str_var}  

where str_var is your string.
