I've found that the stuff SQL Server gives you to do fuzzy matching is pretty clunky. I've had really good luck with my own CLR functions using the Levenshtein distance algorithm and some weighting. Using that algorithm, I've then made a UDF called GetSimilarityScore that takes two strings and returns a score between 0.0 and 1.0. The closer to 1.0 the match is, the better. Then, query with a threshold of >=0.8 or so to get the most likely matches. Something like this:

if object_id('tempdb..#similar') is not null drop table #similar
select a.id, (
    select top 1 x.id
   from MyTable x
   where x.id <> a.id
   order by dbo.GetSimilarityScore(a.MyField, x.MyField) desc
) as MostSimilarId
into #similar
from MyTable a

select *, dbo.GetSimilarityScore(a.MyField, c.MyField)
from MyTable a
join #similar b on a.id = b.id
join MyTable c on b.MostSimilarId = c.id

Just don't do it with really large tables. It's a slow process.

Here's the CLR UDFs:

I just cleaned up RHT's answer to eliminate some warnings and thought I would share. Eclipse did most of the work:

public List<HashMap<String,Object>> convertResultSetToList(ResultSet rs) throws SQLException {
    ResultSetMetaData md = rs.getMetaData();
    int columns = md.getColumnCount();
    List<HashMap<String,Object>> list = new ArrayList<HashMap<String,Object>>();

    while (rs.next()) {
        HashMap<String,Object> row = new HashMap<String, Object>(columns);
        for(int i=1; i<=columns; ++i) {
            row.put(md.getColumnName(i),rs.getObject(i));
        }
        list.add(row);
    }

    return list;
}

I know this has already been answered, but I stumbled across this question and went down the path of using format, which works, but it returns them as strings when I wanted integers.

I just realized that moment comes with date, month and year methods that return the actual integers for each method.

moment().date()
moment().month()  // jan=0, dec=11
moment().year()

Try this

<div *ngFor="let piece of allPieces; let i=index">
{{i}} // this will give index
</div>

To add non-breaking space or real space to your text in html, you can use the   character entity.

SELECT 
    u . *
FROM
    room u
        JOIN
    facilities_r fu ON fu.id_uc = u.id_uc
        AND (fu.id_fu = '4' OR fu.id_fu = '3')
WHERE
    1 and vizibility = '1'
GROUP BY id_uc
ORDER BY u_premium desc , id_uc desc

You must use OR here, not AND.

Since id_fu cannot be equal to 4 and 3, both at once.

Admittedly, I stole this question from somewhere else (can't remember where I read it any more) but thought it was funny:

Q: What is T_PAAMAYIM_NEKUDOTAYIM?
A: Its the scope resolution operator (double colon)

An experienced PHP'er immediately knows what it means. Less experienced (and not Hebrew) developers may want to read this.

But more serious questions now:

Q: What is the cause of this warning: 'Warning: Cannot modify header information - headers already sent', and what is a good practice to prevent it?
A: Cause: body data was sent, causing headers to be sent too.
Prevention: Be sure to execute header specific code first before you output any body data. Be sure you haven't accidentally sent out whitespace or any other characters.

Q: What is wrong with this query: "SELECT * FROM table WHERE id = $_POST[ 'id' ]"?
A: 1. It is vulnarable to SQL injection. Never use user input directly in queries. Sanitize it first. Preferebly use prepared statements (PDO) 2. Don't select all columns (*), but specify every single column. This is predominantly ment to prevent queries hogging up memory when for instance a BLOB column is added at some point in the future.

Q: What is wrong with this if statement: if( !strpos( $haystack, $needle ) ...?
A: strpos returns the index position of where it first found the $needle, which could be 0. Since 0 also resolves to false the solution is to use strict comparison: if( false !== strpos( $haystack, $needle )...

Q: What is the preferred way to write this if statement, and why?
if( 5 == $someVar ) or if( $someVar == 5 )
A: The former, as it prevents accidental assignment of 5 to $someVar when you forget to use 2 equalsigns ($someVar = 5), and will cause an error, the latter won't.

Q: Given this code:

function doSomething( &$arg )
{
    $return = $arg;
    $arg += 1;
    return $return;
}

$a = 3;
$b = doSomething( $a );

...what is the value of $a and $b after the function call and why?
A: $a is 4 and $b is 3. The former because $arg is passed by reference, the latter because the return value of the function is a copy of (not a reference to) the initial value of the argument.

OOP specific

Q: What is the difference between public, protected and private in a class definition?
A: public makes a class member available to "everyone", protected makes the class member available to only itself and derived classes, private makes the class member only available to the class itself.

Q: What is wrong with this code:

class SomeClass
{
    protected $_someMember;

    public function __construct()
    {
        $this->_someMember = 1;
    }

    public static function getSomethingStatic()
    {
        return $this->_someMember * 5; // here's the catch
    }
}

A: Static methods don't have access to $this, because static methods can be executed without instantiating a class.

Q: What is the difference between an interface and an abstract class?
A: An interface defines a contract between an implementing class is and an object that calls the interface. An abstract class pre-defines certain behaviour for classes that will extend it. To a certain degree this can also be considered a contract, since it garantuees certain methods to exist.

Q: What is wrong with classes that predominantly define getters and setters, that map straight to it's internal members, without actually having methods that execute behaviour?
A: This might be a code smell since the object acts as an ennobled array, without much other use.

Q: Why is PHP's implementation of the use of interfaces sub-optimal?
A: PHP doesn't allow you to define the expected return type of the method's, which essentially renders interfaces pretty useless. :-P

In Visual Studio 2012 you have to use (I think in Visual Studio 2010, too)

if $(Configuration) == Debug xcopy

$(ConfigurationName) was listed as a macro, but it wasn't assigned.

Compare: Macros for Build Commands and Properties

So, let's say you have this table:

CREATE TABLE YourTable(Col1 VARCHAR(10))

And you want to change Col1 to VARCHAR(20). What you need to do is this:

ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)

That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5), then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE will fail.

In Java, the equals() method that is inherited from Object is:

public boolean equals(Object other);

In other words, the parameter must be of type Object. This is called overriding; your method public boolean equals(Book other) does what is called overloading to the equals() method.

The ArrayList uses overridden equals() methods to compare contents (e.g. for its contains() and equals() methods), not overloaded ones. In most of your code, calling the one that didn't properly override Object's equals was fine, but not compatible with ArrayList.

So, not overriding the method correctly can cause problems.

I override equals the following everytime:

@Override
public boolean equals(Object other){
    if (other == null) return false;
    if (other == this) return true;
    if (!(other instanceof MyClass)) return false;
    MyClass otherMyClass = (MyClass)other;
    ...test other properties here...
}

The use of the @Override annotation can help a ton with silly mistakes.

Use it whenever you think you are overriding a super class' or interface's method. That way, if you do it the wrong way, you will get a compile error.

It's more than 8 years passed and I am surprised, this issue isn't fixed yet...
I struggled with this simple issue since the most upvoted answer by @Martin lets typing multiple separators, i.e. user can type in "12,,,,,,12,1,,21,2,"
Also, the second concern is that on some devices comma is not shown on the numerical keyboard (or requires multiple pressing of a dot button)

Here is my workaround solution, which solves the mentioned problems and lets user typing '.' and ',', but in EditText he will see the only decimal separator which corresponds to current locale:

editText.apply { addTextChangedListener(DoubleTextChangedListener(this)) }

And the text watcher:

  open class DoubleTextChangedListener(private val et: EditText) : TextWatcher {

    init {
        et.inputType = InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_DECIMAL
        et.keyListener = DigitsKeyListener.getInstance("0123456789.,")
    }

    private val separator = DecimalFormatSymbols.getInstance().decimalSeparator

    override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
        //empty
    }

    @CallSuper
    override fun onTextChanged(s: CharSequence, start: Int, before: Int, count: Int) {
        et.run {
            removeTextChangedListener(this@DoubleTextChangedListener)
            val formatted = toLocalizedDecimal(s.toString(), separator)
            setText(formatted)
            setSelection(formatted.length)
            addTextChangedListener(this@DoubleTextChangedListener)
        }
    }

    override fun afterTextChanged(s: Editable?) {
        // empty
    }

    /**
     * Formats input to a decimal. Leaves the only separator (or none), which matches [separator].
     * Examples:
     * 1. [s]="12.12", [separator]=',' -> result= "12,12"
     * 2. [s]="12.12", [separator]='.' -> result= "12.12"
     * 4. [s]="12,12", [separator]='.' -> result= "12.12"
     * 5. [s]="12,12,,..,,,,,34..,", [separator]=',' -> result= "12,1234"
     * 6. [s]="12.12,,..,,,,,34..,", [separator]='.' -> result= "12.1234"
     * 7. [s]="5" -> result= "5"
     */
    private fun toLocalizedDecimal(s: String, separator: Char): String {
        val cleared = s.replace(",", ".")
        val splitted = cleared.split('.').filter { it.isNotBlank() }
        return when (splitted.size) {
            0 -> s
            1 -> cleared.replace('.', separator).replaceAfter(separator, "")
            2 -> splitted.joinToString(separator.toString())
            else -> splitted[0]
                    .plus(separator)
                    .plus(splitted.subList(1, splitted.size - 1).joinToString(""))
        }
    }
}

An alternative with data.table:

library(data.table)
df1 = data.frame(a = c(1:5), b = c(6:10))
df2 = data.frame(a = c(11:15), b = c(16:20), c = LETTERS[1:5])
rbindlist(list(df1, df2), fill = TRUE)

rbind will also work in data.table as long as the objects are converted to data.table objects, so

rbind(setDT(df1), setDT(df2), fill=TRUE)

will also work in this situation. This can be preferable when you have a couple of data.tables and don't want to construct a list.

This bash function has the minimal dependency(only sort and bash):

shuf() {
while read -r x;do
    echo $RANDOM$'\x1f'$x
done | sort |
while IFS=$'\x1f' read -r x y;do
    echo $y
done
}

The problem is, that the internal focus event is not transformed to jQuery event, so I've modified the plugin and added the focus event to the EventRelay on line 2063 of Select2 4.0.3:

EventRelay.prototype.bind = function (decorated, container, $container) {
    var self = this;
    var relayEvents = [
      'open', 'opening',
      'close', 'closing',
      'select', 'selecting',
      'unselect', 'unselecting',
      'focus'
    ]};

Then it is enough to open the select2 when the focus occurs:

$('#select2').on('select2:focus', function(evt){
    $(this).select2('open');
});

Works well on Chrome 54, IE 11, FF 49, Opera 40

ORA-06512 is part of the error stack. It gives us the line number where the exception occurred, but not the cause of the exception. That is usually indicated in the rest of the stack (which you have still not posted).

In a comment you said

"still, the error comes when pNum is not between 12 and 14; when pNum is between 12 and 14 it does not fail"

Well, your code does this:

IF ((pNum < 12) OR (pNum > 14)) THEN     
    RAISE vSOME_EX;

That is, it raises an exception when pNum is not between 12 and 14. So does the rest of the error stack include this line?

ORA-06510: PL/SQL: unhandled user-defined exception

If so, all you need to do is add an exception block to handle the error. Perhaps:

PROCEDURE PX(pNum INT,pIdM INT,pCv VARCHAR2,pSup FLOAT)
AS
    vSOME_EX EXCEPTION;

BEGIN 
    IF ((pNum < 12) OR (pNum > 14)) THEN     
        RAISE vSOME_EX;
    ELSE  
        EXECUTE IMMEDIATE  'INSERT INTO M'||pNum||'GR (CV, SUP, IDM'||pNum||') VALUES('||pCv||', '||pSup||', '||pIdM||')';
    END IF;
exception
    when vsome_ex then
         raise_application_error(-20000
                                 , 'This is not a valid table:  M'||pNum||'GR');

END PX;

Here is a permissively-licensed C library with a variety of different FFT implementations, each of which is in its own self-contained C-file.

package com.mycompany;

import javax.validation.constraints.Min;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

public class Car {

    @NotNull
    private String manufacturer;

    @NotNull
    @Size(min = 2, max = 14)
    private String licensePlate;

    @Min(2)
    private int seatCount;

    public Car(String manufacturer, String licencePlate, int seatCount) {
        this.manufacturer = manufacturer;
        this.licensePlate = licencePlate;
        this.seatCount = seatCount;
    }

    //getters and setters ...
}

@NotNull, @Size and @Min are so-called constraint annotations, that we use to declare constraints, which shall be applied to the fields of a Car instance:

manufacturer shall never be null

licensePlate shall never be null and must be between 2 and 14 characters long

seatCount shall be at least 2.

In my case, I was setting "Embed Without Signing" on some frameworks in "Project -> General -> Frameworks, Libraries, and Embedded Content" tab, which causes unknown conflicts in the project.

It finally works when I set "Embed and Sign" to those frameworks which needed to be embedded.

If you want to be a good citizen, take the extra time to implement Parcelable since it will perform 10 times faster and use less resources.

However, in most cases, the slowness of Serializable won’t be noticeable. Feel free to use it but remember that serialization is an expensive operation so keep it to a minimum.

If you are trying to pass a list with thousands of serialized objects, it is possible that the whole process will take more than a second. It can make transitions or rotation from portrait to lanscape feel very sluggish.

JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.

var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
    //red
    textBox.style.backgroundColor = "#FF0000";
}
else
{
    //green
    textBox.style.backgroundColor = "#00FF00";
}

If the method you are testing for is defined as an optional method in a @objc protocol (which sounds like your case), then use the optional chaining pattern as:

if let result = object.method?(args) {
  /* method exists, result assigned, use result */
}
else { ... }

When the method is declare as returning Void, simply use:

if object.method?(args) { ... }

You can use javac *.java command to compile all you java sources. Also you should learn a little about classpath because it seems that you should set appropriate classpath for succesful compilation (because your IDE use some libraries for building WebService clients). Also I can recommend you to check wich command your IDE use to build your project.

I wanted to use the C++11 answer, but I could not because GCC 4.9 does not support std::put_time.

std::put_time implementation status in GCC?

I ended up using some C++11 to slightly improve the non-C++11 answer. For those that can't use GCC 5, but would still like some C++11 in their date/time format:

 std::array<char, 64> buffer;
 buffer.fill(0);
 time_t rawtime;
 time(&rawtime);
 const auto timeinfo = localtime(&rawtime);
 strftime(buffer.data(), sizeof(buffer), "%d-%m-%Y %H-%M-%S", timeinfo);
 std::string timeStr(buffer.data());

Type IF /? to get help about if, it clearly explains how to use IF EXIST.

To delete a complete tree except some folders, see the answer of this question: Windows batch script to delete everything in a folder except one

Finally copying just means calling COPY and calling another bat file can be done like this:

MYOTHERBATFILE.BAT sync.bat myprogram.ini

SELECT * FROM testcases1 t WHERE NOT EXISTS ( SELECT 1
FROM executions1 i WHERE t.tc_id = i.tc_id and t.pro_id=i.pro_id and pro_id=7 and version_id=5 ) and pro_id=7 ;

Here testcases1 table contains all datas and executions1 table contains some data among testcases1 table. I am retrieving only the datas which are not present in exections1 table. ( and even I am giving some conditions inside that you can also give.) specify condition which should not be there in retrieving data should be inside brackets.

You can assign an iterable to side_effect, and the mock will return the next value in the sequence each time it is called:

>>> from unittest.mock import Mock
>>> m = Mock()
>>> m.side_effect = ['foo', 'bar', 'baz']
>>> m()
'foo'
>>> m()
'bar'
>>> m()
'baz'

Quoting the Mock() documentation:

If side_effect is an iterable then each call to the mock will return the next value from the iterable.

Maybe a more Laravel way to solve this problem is to use a collection and loop it inserting with the model taking advantage of the timestamps.

<?php

use App\Continent;
use Illuminate\Database\Seeder;

class InitialSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        collect([
            ['name' => 'América'],
            ['name' => 'África'],
            ['name' => 'Europa'],
            ['name' => 'Asia'],
            ['name' => 'Oceanía'],
        ])->each(function ($item, $key) {
            Continent::forceCreate($item);
        });
    }
}

EDIT:

Sorry for my misunderstanding. For bulk inserting this could help and maybe with this you can make good seeders and optimize them a bit.

<?php

use App\Continent;
use Carbon\Carbon;
use Illuminate\Database\Seeder;

class InitialSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $timestamp = Carbon::now();
        $password = bcrypt('secret');

        $continents = [
            [
                'name' => 'América'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'África'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'Europa'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'Asia'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'Oceanía'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
        ];

        Continent::insert($continents);
    }
}

If you are dealing with money I suggest checking the Money design pattern (originally from Martin Fowler's book on enterprise architectural design).

I suggest reading this link for the motivation: http://wiki.moredesignpatterns.com/space/Value+Object+Motivation+v2

Yes this is happening because you are accessing mi variable from within your anonymous inner class, what happens deep inside is that another copy of your variable is created and will be use inside the anonymous inner class, so for data consistency the compiler will try restrict you from changing the value of mi so that's why its telling you to set it to final.

This is Microsoft's recommended way to handle WCF client calls:

For more detail see: Expected Exceptions

try
{
    ...
    double result = client.Add(value1, value2);
    ...
    client.Close();
}
catch (TimeoutException exception)
{
    Console.WriteLine("Got {0}", exception.GetType());
    client.Abort();
}
catch (CommunicationException exception)
{
    Console.WriteLine("Got {0}", exception.GetType());
    client.Abort();
}

Additional information So many people seem to be asking this question on WCF that Microsoft even created a dedicated sample to demonstrate how to handle exceptions:

c:\WF_WCF_Samples\WCF\Basic\Client\ExpectedExceptions\CS\client

Download the sample: C# or VB

Considering that there are so many issues involving the using statement, (heated?) Internal discussions and threads on this issue, I'm not going to waste my time trying to become a code cowboy and find a cleaner way. I'll just suck it up, and implement WCF clients this verbose (yet trusted) way for my server applications.

Optional Additional Failures to catch

Many exceptions derive from CommunicationException and I don't think most of those exceptions should be retried. I drudged through each exception on MSDN and found a short list of retry-able exceptions (in addition to TimeOutException above). Do let me know if I missed an exception that should be retried.

  // The following is typically thrown on the client when a channel is terminated due to the server closing the connection.
catch (ChannelTerminatedException cte)
{
secureSecretService.Abort();
// todo: Implement delay (backoff) and retry
}

// The following is thrown when a remote endpoint could not be found or reached.  The endpoint may not be found or 
// reachable because the remote endpoint is down, the remote endpoint is unreachable, or because the remote network is unreachable.
catch (EndpointNotFoundException enfe)
{
secureSecretService.Abort();
// todo: Implement delay (backoff) and retry
}

// The following exception that is thrown when a server is too busy to accept a message.
catch (ServerTooBusyException stbe)
{
secureSecretService.Abort();
// todo: Implement delay (backoff) and retry
}

Admittedly, this is a bit of mundane code to write. I currently prefer this answer, and don't see any "hacks" in that code that may cause issues down the road.

Since as Phil says in his comment on the original question, this is unique and there is no other info on SO on in google, I thought I should also share my results:

In my app FileProvider worked out of the box to share files using the share intent. There was no special configuration or code necessary, beyond that to setup the FileProvider. In my manifest.xml I placed:

    <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="com.my.apps.package.files"
        android:exported="false"
        android:grantUriPermissions="true" >
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/my_paths" />
    </provider>

In my_paths.xml I have:

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="files" path="." />
</paths>

In my code I have:

    Intent shareIntent = new Intent();
    shareIntent.setAction(Intent.ACTION_SEND);
    shareIntent.setType("application/xml");

    Uri uri = FileProvider.getUriForFile(this, "com.my.apps.package.files", fileToShare);
    shareIntent.putExtra(Intent.EXTRA_STREAM, uri);

    startActivity(Intent.createChooser(shareIntent, getResources().getText(R.string.share_file)));

And I am able to share my files store in my apps private storage with apps such as Gmail and google drive without any trouble.

Magic word is: isset

Validate the entry:

if(isset($manta_option['iso_format_recent_works']) && $manta_option['iso_format_recent_works'] == 1){
    $theme_img = 'recent_works_thumbnail';
} else {
    $theme_img = 'recent_works_iso_thumbnail';
}

if The wampserver Version 2.5 then change apache configuration as

httpd.conf (apache configuration file): From

#LoadModule rewrite_module modules/mod_rewrite.so** 

To ,delete the #

LoadModule rewrite_module modules/mod_rewrite.so** 

this working fine to me

The email addresses I want to validate are going to be used by an ASP.NET web application using the System.Net.Mail namespace to send emails to a list of people.

So, rather than using some very complex regular expression, I just try to create a MailAddress instance from the address. The MailAddress constructor will throw an exception if the address is not formed properly. This way, I know I can at least get the email out of the door. Of course this is server-side validation, but at a minimum you need that anyway.

protected void emailValidator_ServerValidate(object source, ServerValidateEventArgs args)
{
    try
    {
        var a = new MailAddress(txtEmail.Text);
    }
    catch (Exception ex)
    {
        args.IsValid = false;
        emailValidator.ErrorMessage = "email: " + ex.Message;
    }
}

Use empty(). It checks for both empty strings and null.

if (!empty($_POST['user'])) {
  // do stuff
}

From the manual:

The following things are considered to be empty:

"" (an empty string)  
0 (0 as an integer)  
0.0 (0 as a float)  
"0" (0 as a string)    
NULL  
FALSE  
array() (an empty array)  
var $var; (a variable declared, but without a value in a class)  

You could use

new SimpleDateFormat( "yyyyMMdd" ).parse( "20100520" )

You can read it from the input stream:

public ActionResult ManagePhotos(ManagePhotos model)
{
    if (ModelState.IsValid)
    {
        byte[] image = new byte[model.File.ContentLength];
        model.File.InputStream.Read(image, 0, image.Length); 

        // TODO: Do something with the byte array here
    }
    ...
}

And if you intend to directly save the file to the disk you could use the model.File.SaveAs method. You might find the following blog post useful.

I found the possible way to write.

Server Side -

app.get('/main', function(req, res) {

  var name = 'hello';

  res.render(__dirname + "/views/layouts/main.html", {name:name});

});

Client side (main.html) -

<h1><%= name %></h1>

    string stringToDecrypt = CypherText.Replace(" ", "+");
    int len = stringToDecrypt.Length;
    byte[] inputByteArray = Convert.FromBase64String(stringToDecrypt); 

To anyone who doesn't want to use DATE_SUB, use CURRENT_DATE:

SELECT CURRENT_DATE - INTERVAL 30 DAY

Here's a simpler way:

a = [-2,1,5,3,8,5,6]
b = [1,2,5]
c = [e for i, e in enumerate(a) if i in b]

You can set android:text="your text";

<EditText
    android:id="@+id/editTextName"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/intro_name"/>

Actually, it will takes 101 bytes.

MySQL Reference

Lodash has a _.pickBy function which does exactly what you're looking for.

var thing = {_x000D_
  "a": 123,_x000D_
  "b": 456,_x000D_
  "abc": 6789_x000D_
};_x000D_
_x000D_
var result = _.pickBy(thing, function(value, key) {_x000D_
  return _.startsWith(key, "a");_x000D_
});_x000D_
_x000D_
console.log(result.abc) // 6789_x000D_
console.log(result.b)   // undefined

<script src="https://cdn.jsdelivr.net/lodash/4.16.4/lodash.min.js"></script>

SessionFactory: "One SessionFactory per application per DataBase" ( e.g., if you use 3 DataBase's in our application , you need to create sessionFactory object per each DB , totally you need to create 3 sessionFactorys . or else if you have only one DataBase One sessionfactory is enough ).

Session: "One session for one request-response cycle". you can open session when request came and you can close session after completion of request process. Note:-Don't use one session for web application.

I took @hajamie's solution and wrapped it up into a slightly more convenient script wrapper.

I added an option to start from an offset before the end of the file, so you can use the tail-like functionality of reading a certain amount from the end of the file. Note the offset is in bytes, not lines.

There's also an option to continue waiting for more content.

Examples (assuming you save this as TailFile.ps1):

.\TailFile.ps1 -File .\path\to\myfile.log -InitialOffset 1000000
.\TailFile.ps1 -File .\path\to\myfile.log -InitialOffset 1000000 -Follow:$true
.\TailFile.ps1 -File .\path\to\myfile.log -Follow:$true

And here is the script itself...

param (
    [Parameter(Mandatory=$true,HelpMessage="Enter the path to a file to tail")][string]$File = "",
    [Parameter(Mandatory=$true,HelpMessage="Enter the number of bytes from the end of the file")][int]$InitialOffset = 10248,
    [Parameter(Mandatory=$false,HelpMessage="Continuing monitoring the file for new additions?")][boolean]$Follow = $false
)

$ci = get-childitem $File
$fullName = $ci.FullName

$reader = new-object System.IO.StreamReader(New-Object IO.FileStream($fullName, [System.IO.FileMode]::Open, [System.IO.FileAccess]::Read, [IO.FileShare]::ReadWrite))
#start at the end of the file
$lastMaxOffset = $reader.BaseStream.Length - $InitialOffset

while ($true)
{
    #if the file size has not changed, idle
    if ($reader.BaseStream.Length -ge $lastMaxOffset) {
        #seek to the last max offset
        $reader.BaseStream.Seek($lastMaxOffset, [System.IO.SeekOrigin]::Begin) | out-null

        #read out of the file until the EOF
        $line = ""
        while (($line = $reader.ReadLine()) -ne $null) {
            write-output $line
        }

        #update the last max offset
        $lastMaxOffset = $reader.BaseStream.Position
    }

    if($Follow){
        Start-Sleep -m 100
    } else {
        break;
    }
}

Using some of the answers on this page and here, I came up with my own answer as none of these answers fully solved it for me.

Here is crux of it

var startDate = "27 Apr 2017";
var numOfYears = 1;
var expireDate = new Date(startDate);
expireDate.setFullYear(expireDate.getFullYear() + numOfYears);
expireDate.setDate(expireDate.getDate() -1);

And here a a JSFiddle that has a working example: https://jsfiddle.net/wavesailor/g9a6qqq5/

Run the app in debug mode and set a breakpoint on if (requestCode == SELECT_PICTURE) and inspect each variable as you step through to ensure it is being set as expected. If you are getting a NPE on img.setImageURI(selectedImageUri); then either img or selectedImageUri are not set.

Yes, but when argument matching for a reference, the implicit array to pointer isn't automatic, so you need something like:

void foo( double (&array)[42] );

or

void foo( double (&array)[] );

Be aware, however, that when matching, double [42] and double [] are distinct types. If you have an array of an unknown dimension, it will match the second, but not the first, and if you have an array with 42 elements, it will match the first but not the second. (The latter is, IMHO, very counter-intuitive.)

In the second case, you'll also have to pass the dimension, since there's no way to recover it once you're inside the function.

Since IPv4 addresses are 4 byte long, you could use an INT (UNSIGNED) that has exactly 4 bytes:

`ipv4` INT UNSIGNED

And INET_ATON and INET_NTOA to convert them:

INSERT INTO `table` (`ipv4`) VALUES (INET_ATON("127.0.0.1"));
SELECT INET_NTOA(`ipv4`) FROM `table`;

For IPv6 addresses you could use a BINARY instead:

`ipv6` BINARY(16)

And use PHP’s inet_pton and inet_ntop for conversion:

'INSERT INTO `table` (`ipv6`) VALUES ("'.mysqli_real_escape_string(inet_pton('2001:4860:a005::68')).'")'
'SELECT `ipv6` FROM `table`'
$ipv6 = inet_pton($row['ipv6']);

This answer is specific to situations where the objects to be passed has nested class structure. With nested class structure, making it Parcelable or Serializeable is a bit tedious. And, the process of serialising an object is not efficient on Android. Consider the example below,

class Myclass    {
  int a;
  class SubClass    {
       int b;
  }
}

With Google's GSON library, you can directly parse an object into a JSON formatted String and convert it back to the object format after usage. For example,

MyClass src = new MyClass();
Gson gS = new Gson();
String target = gS.toJson(src); // Converts the object to a JSON String

Now you can pass this String across activities as a StringExtra with the activity intent.

Intent i = new Intent(FromActivity.this, ToActivity.class);
i.putExtra("MyObjectAsString", target);

Then in the receiving activity, create the original object from the string representation.

String target = getIntent().getStringExtra("MyObjectAsString");
MyClass src = gS.fromJson(target, MyClass.class); // Converts the JSON String to an Object

It keeps the original classes clean and reusable. Above of all, if these class objects are created from the web as JSON objects, then this solution is very efficient and time saving.

UPDATE

While the above explained method works for most situations, for obvious performance reasons, do not rely on Android's bundled-extra system to pass objects around. There are a number of solutions makes this process flexible and efficient, here are a few. Each has its own pros and cons.

1. Eventbus
2. Otto

The listed answers won't work if the results of the AJAX form submit affects the HTML outside the scope of the modal before the modal finishes closing. In my case, the result was a grayed out (fade) screen where I could see the page update, but could not interact with any of the page elements.

My solution:

$(document).on("click", "#send-email-submit-button", function(e){
    $('#send-new-email-modal').modal('hide')
});

 $(document).on("submit", "#send-email-form", function(e){
    e.preventDefault();
    var querystring = $(this).serialize();
    $.ajax({
        type: "POST",
        url: "sendEmailMessage",
        data : querystring,
        success : function(response) {
            $('#send-new-email-modal').on('hidden.bs.modal', function () {
                $('#contacts-render-target').html(response);
            }
    });
    return false;
});

Note: My modal form was inside a parent div that was already rendered via AJAX, thus the need to anchor the event listener to document.

You can do it with strtol, like this:

char *str = "ab234cid*(s349*(20kd", *p = str;
while (*p) { // While there are more characters to process...
    if ( isdigit(*p) || ( (*p=='-'||*p=='+') && isdigit(*(p+1)) )) {
        // Found a number
        long val = strtol(p, &p, 10); // Read number
        printf("%ld\n", val); // and print it.
    } else {
        // Otherwise, move on to the next character.
        p++;
    }
}

Link to ideone.

std::pair already has the required comparison operators, which perform lexicographical comparisons using both elements of each pair. To use this, you just have to provide the comparison operators for types for types K and V.

Also bear in mind that std::sort requires a strict weak ordeing comparison, and <= does not satisfy that. You would need, for example, a less-than comparison < for K and V. With that in place, all you need is

std::vector<pair<K,V>> items; 
std::sort(items.begin(), items.end()); 

If you really need to provide your own comparison function, then you need something along the lines of

template <typename K, typename V>
bool comparePairs(const std::pair<K,V>& lhs, const std::pair<K,V>& rhs)
{
  return lhs.first < rhs.first;
}

One should not specify AUTOINCREMENT keyword near PRIMARY KEY. Example of creating autoincrement primary key and inserting:

$ sqlite3 ex1

CREATE TABLE IF NOT EXISTS room(room_id INTEGER PRIMARY KEY, name VARCHAR(25) NOT NULL, home_id VARCHAR(25) NOT NULL);

INSERT INTO room(name, home_id) VALUES ('test', 'home id test');

INSERT INTO room(name, home_id) VALUES ('test 2', 'home id test 2');

SELECT * FROM room;

will give:

1|test|home id test
2|test 2|home id test 2

Rename MySQL Column with ALTER TABLE Command

ALTER TABLE is an essential command used to change the structure of a MySQL table. You can use it to add or delete columns, change the type of data within the columns, and even rename entire databases. The function that concerns us the most is how to utilize ALTER TABLE to rename a column.

Clauses give us additional control over the renaming process. The RENAME COLUMN and CHANGE clause both allow for the names of existing columns to be altered. The difference is that the CHANGE clause can also be used to alter the data types of a column. The commands are straightforward, and you may use the clause that fits your requirements best.

How to Use the RENAME COLUMN Clause (MySQL 8.0)

The simplest way to rename a column is to use the ALTER TABLE command with the RENAME COLUMN clause. This clause is available since MySQL version 8.0.

Let’s illustrate its simple syntax. To change a column name, enter the following statement in your MySQL shell:

ALTER TABLE your_table_name RENAME COLUMN original_column_name TO new_column_name;

Exchange the your_table_name, original_column_name, and new_column_name with your table and column names. Keep in mind that you cannot rename a column to a name that already exists in the table.

Note: The word COLUMN is obligatory for the ALTER TABLE RENAME COLUMN command. ALTER TABLE RENAME is the existing syntax to rename the entire table.

The RENAME COLUMN clause can only be used to rename a column. If you need additional functions, such as changing the data definition, or position of a column, you need to use the CHANGE clause instead.

Rename MySQL Column with CHANGE Clause

The CHANGE clause offers important additions to the renaming process. It can be used to rename a column and change the data type of that column with the same command.

Enter the following command in your MySQL client shell to change the name of the column and its definition:

ALTER TABLE your_table_name CHANGE original_column_name new_col_name data_type;

The data_type element is mandatory, even if you want to keep the existing datatype.

Use additional options to further manipulate table columns. The CHANGE also allows you to place the column in a different position in the table by using the optional FIRST | AFTER column_name clause. For example:

ALTER TABLE your_table_name CHANGE original_column_name new_col_name y_data_type AFTER column_x;

You have successfully changed the name of the column, changed the data type to y_data_type, and positioned the column after column_x.

Generate the scripts?

Generate a script to create the table then generate a script to insert the data.

check-out SP_ Genereate_Inserts for generating the data insert script.

I'm failing to see the problem here. The code looks good to me.

The only thing I can think of is that the try/catch blocks are redundant -- Color is a struct and R, G, and B are bytes, so c can't be null and c.R.ToString(), c.G.ToString(), and c.B.ToString() can't actually fail (the only way I can see them failing is with a NullReferenceException, and none of them can actually be null).

You could clean the whole thing up using the following:

private static String HexConverter(System.Drawing.Color c)
{
    return "#" + c.R.ToString("X2") + c.G.ToString("X2") + c.B.ToString("X2");
}

private static String RGBConverter(System.Drawing.Color c)
{
    return "RGB(" + c.R.ToString() + "," + c.G.ToString() + "," + c.B.ToString() + ")";
}

You could try a formatter like this

They will always be limited because they don't (and can't) know what user defined functions you may have defined in your database (or which built-in functions you have or don't have access to).

You could also look at ANTLR (but that would be an offline solution)

Not that I know of, but what about doing something like this when you create an instance of TestedClass that you want to test:

TestedClass toTest = new TestedClass() {
    public LoginContext login(String user, String password) {
        //return mocked LoginContext
    }
};

Another option would be to use Mockito to create an instance of TestedClass and let the mocked instance return a LoginContext.

use printf with "%05d" e.g.

printf "%05d" 1

Use RxJS in a Service

What about in a situation where you have a Service that's holding state for example. How could I push changes to that Service, and other random components on the page be aware of such a change? Been struggling with tackling this problem lately

Build a service with RxJS Extensions for Angular.

<script src="//unpkg.com/angular/angular.js"></script>
<script src="//unpkg.com/rx/dist/rx.all.js"></script>
<script src="//unpkg.com/rx-angular/dist/rx.angular.js"></script>

var app = angular.module('myApp', ['rx']);

app.factory("DataService", function(rx) {
  var subject = new rx.Subject(); 
  var data = "Initial";

  return {
      set: function set(d){
        data = d;
        subject.onNext(d);
      },
      get: function get() {
        return data;
      },
      subscribe: function (o) {
         return subject.subscribe(o);
      }
  };
});

Then simply subscribe to the changes.

app.controller('displayCtrl', function(DataService) {
  var $ctrl = this;

  $ctrl.data = DataService.get();
  var subscription = DataService.subscribe(function onNext(d) {
      $ctrl.data = d;
  });

  this.$onDestroy = function() {
      subscription.dispose();
  };
});

Clients can subscribe to changes with DataService.subscribe and producers can push changes with DataService.set.

Remove specific index(i removed 16 and 21 from matrix)

import numpy as np
mat = np.arange(12,26)
a = [4,9]
del_map = np.delete(mat, a)
del_map.reshape(3,4)

Output:

array([[12, 13, 14, 15],
      [17, 18, 19, 20],
      [22, 23, 24, 25]])

Spring provides an elegant org.springframework.util.StopWatch class (spring-core module).

StopWatch stopWatch = new StopWatch();

stopWatch.start();
// Do something
stopWatch.stop();

System.out.println(stopWatch.getTotalTimeMillis());

There seem to be many answers suggesting:

process.stdout.write

Error logs should be emitted on:

process.stderr

Instead use:

console.error

For anyone who is wonder why process.stdout.write('\033[0G'); wasn't doing anything it's because stdout is buffered and you need to wait for drain event (more info).

If write returns false it will fire a drain event.

I think a 32 bit JVM has a maximum of 2GB memory.This might be out of date though. If I understood correctly, you set the -Xmx on Eclipse launcher. If you want to increase the memory for the program you run from Eclipse, you should define -Xmx in the "Run->Run configurations..."(select your class and open the Arguments tab put it in the VM arguments area) menu, and NOT on Eclipse startup

Edit: details you asked for. in Eclipse 3.4

1. Run->Run Configurations...

2. if your class is not listed in the list on the left in the "Java Application" subtree, click on "New Launch configuration" in the upper left corner

3. on the right, "Main" tab make sure the project and the class are the right ones

4. select the "Arguments" tab on the right. this one has two text areas. one is for the program arguments that get in to the args[] array supplied to your main method. the other one is for the VM arguments. put into the one with the VM arguments(lower one iirc) the following:
   -Xmx2048m

   I think that 1024m should more than enough for what you need though!

5. Click Apply, then Click Run

6. Should work :)

According to the documentation, use a relative path for a local jar dependency as follows:

dependencies {
    implementation files('libs/something_local.jar')
}

Use this to get time from 00:00:00 to 23:59:59

If your time is having date from it by using 'LT or LTS'

var now = moment('23:59:59','HHmmss').format("HH:mm:ss")

Due to @zerkems comment:

i should convert my strings to JSON object and then call the equal method:

var x = eval("(" + remoteJSON + ')');
var y = eval("(" + localJSON + ')');

function jsonequals(x, y) {
    // If both x and y are null or undefined and exactly the same
    if ( x === y ) {
        return true;
    }

    // If they are not strictly equal, they both need to be Objects
    if ( ! ( x instanceof Object ) || ! ( y instanceof Object ) ) {
        return false;
    }

    // They must have the exact same prototype chain, the closest we can do is
    // test the constructor.
    if ( x.constructor !== y.constructor ) {
        return false;
    }

    for ( var p in x ) {
        // Inherited properties were tested using x.constructor === y.constructor
        if ( x.hasOwnProperty( p ) ) {
            // Allows comparing x[ p ] and y[ p ] when set to undefined
            if ( ! y.hasOwnProperty( p ) ) {
                return false;
            }

            // If they have the same strict value or identity then they are equal
            if ( x[ p ] === y[ p ] ) {
                continue;
            }

            // Numbers, Strings, Functions, Booleans must be strictly equal
            if ( typeof( x[ p ] ) !== "object" ) {
                return false;
            }

            // Objects and Arrays must be tested recursively

                return false;
            }
        }

Changed Idolons code a little. This will capitalize words when getting the device model.

        return s;
    else {
        StringBuilder phrase = new StringBuilder();
        boolean next = true;
        for (char c : s.toCharArray()) {
            if (next && Character.isLetter(c) || Character.isWhitespace(c))
                next = Character.isWhitespace(c = Character.toUpperCase(c));

YES

...assuming that there is some maximum number of nestings you'd be happy to stop at.

Let me explain.

@torsten-marek is right that a regular expression cannot check for nested patterns like this, BUT it is possible to define a nested regex pattern which will allow you to capture nested structures like this up to some maximum depth. I created one to capture EBNF-style comments (try it out here), like:

(* This is a comment (* this is nested inside (* another level! *) hey *) yo *)

The regex (for single-depth comments) is the following:

m{1} = \(+\*+(?:[^*(]|(?:\*+[^)*])|(?:\(+[^*(]))*\*+\)+

This could easily be adapted for your purposes by replacing the \(+\*+ and \*+\)+ with { and } and replacing everything in between with a simple [^{}]:

p{1} = \{(?:[^{}])*\}

(Here's the link to try that out.)

To nest, just allow this pattern within the block itself:

p{2} = \{(?:(?:p{1})|(?:[^{}]))*\}
  ...or...
p{2} = \{(?:(?:\{(?:[^{}])*\})|(?:[^{}]))*\}

To find triple-nested blocks, use:

p{3} = \{(?:(?:p{2})|(?:[^{}]))*\}
  ...or...
p{3} = \{(?:(?:\{(?:(?:\{(?:[^{}])*\})|(?:[^{}]))*\})|(?:[^{}]))*\}

A clear pattern has emerged. To find comments nested to a depth of N, simply use the regex:

p{N} = \{(?:(?:p{N-1})|(?:[^{}]))*\}

  where N > 1 and
  p{1} = \{(?:[^{}])*\}

A script could be written to recursively generate these regexes, but that's beyond the scope of what I need this for. (This is left as an exercise for the reader. )

No. Python Strings are immutable.

>>> s='355879ACB6'
>>> s[4:4] = '-'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'str' object does not support item assignment

It is, however, possible to create a new string that has the inserted character:

>>> s[:4] + '-' + s[4:]
'3558-79ACB6'

I came across .netrc and found it relevant to this.

Create a file ~/.netrc with the following content:

machine github.com
    login <github username>
    password <github password or Personal access tokens >

Done!

Additionally, for latest GO versions, you might need to add this to the environment variables GOPRIVATE=github.com (I've added it to my .zshrc)

netrc also makes my development environment setup better as my personal github access for HTTPS is been configured now to be used across the machine (just like my SSH configuration).

Generate GitHub personal access tokens: https://github.com/settings/tokens

See this answer for its use with Git on Windows specifically

Ref: netrc man page

If you want to stick with the SSH authentication, then mask the request to use ssh forcefully

git config --global url."[email protected]:".insteadOf "https://github.com/"

You can add a callback function to your DatePicker to tell it to blur the input field before showing the DatePicker.

$('.selector').datepicker({

I had to also remove session cookies like this:

session_start(); 
$_SESSION = []; 

// If it's desired to kill the session, also 
// delete the session cookie. 
// Note: This will destroy the session, and 
// not just the session data! 
if (ini_get("session.use_cookies")) { 
    $params = session_get_cookie_params(); 
    setcookie(session_name(), '', time() - 42000, 
        $params["path"], $params["domain"], 
        $params["secure"], $params["httponly"] 
    ); 
} 

// Finally, destroy the session. 
session_destroy();

For this purpose and if i dont have boolean variable i use the following:

<li th:class="${#strings.contains(content.language,'CZ')} ? active : ''">

There is a simple solution that consists in using stepi, which in turns moves forward by 1 asm instruction and shows the surrounding asm code.

Try string.Remove();

string str = "1,5,12,34,";
string removecomma = str.Remove(str.Length-1);
MessageBox.Show(removecomma);

Using pretty much the same approach as used by Burnash, for the final result you can use ...

=regexextract(A1,"[0-9]+")+A2

where A1 houses the string with text and number and A2 houses the date of interest

If you want to pass two values, you can use this approach

<asp:LinkButton ID="RemoveFroRole" Text="Remove From Role" runat="server"
CommandName='<%# Eval("UserName") %>' CommandArgument='<%# Eval("RoleName") %>'
 OnClick="RemoveFromRole_Click" />

Basically I am treating {CommmandName,CommandArgument} as key value. Set both from database field. You will have to use OnClick event and use OnCommand event in this case, which I think is more clean code.

For those that use coffeescript, I've put the code we use globally to disable the submit buttons on our most widely used form. An adaption of Adil's answer above.

$('#new_post button').prop 'disabled', true
$('#new_post #post_message').keyup ->
    $('#new_post button').prop 'disabled', if @value == '' then true else false
    return

<a href="javascript:call_func();">...</a>

where the function then has to return false so that the browser doesn't go to another page.

But I'd recommend to use jQuery (with $(...).click(function () {})))

Wrap your all statements in !IsPostBack condition on page load.

protected void Page_Load(object sender, EventArgs e)
{
   if(!IsPostBack)
   {
      // all statements
   }
}

This will fix your issue.

OAuth

Used for delegated authorization only -- meaning you are authorizing a third-party service access to use personal data, without giving out a password. Also OAuth "sessions" generally live longer than user sessions. Meaning that OAuth is designed to allow authorization

i.e. Flickr uses OAuth to allow third-party services to post and edit a persons picture on their behalf, without them having to give out their flicker username and password.

OpenID

Used to authenticate single sign-on identity. All OpenID is supposed to do is allow an OpenID provider to prove that you say you are. However many sites use identity authentication to provide authorization (however the two can be separated out)

i.e. One shows their passport at the airport to authenticate (or prove) the person's who's name is on the ticket they are using is them.

Your only option seems to be client-side validation, because server side means the file was already uploaded. Also the MIME type is usually dictated by the file extension.

use a JavaScript Framework like jQuery to overload the onsubmit event of the form. Then check the extension. This will limit most attempts. However if a person changes an image to extension XLS then you will have a problem.

I don't know if this is an option for you, but you have more client side control when using something like Silverlight or Flash to upload. You may consider using one of these technologies for your upload process.

FWIW:

$ python -m timeit -s "import re" "re.match('hello', 'hello world')"
100000 loops, best of 3: 3.82 usec per loop

$ python -m timeit -s "import re; h=re.compile('hello')" "h.match('hello world')"
1000000 loops, best of 3: 1.26 usec per loop

so, if you're going to be using the same regex a lot, it may be worth it to do re.compile (especially for more complex regexes).

The standard arguments against premature optimization apply, but I don't think you really lose much clarity/straightforwardness by using re.compile if you suspect that your regexps may become a performance bottleneck.

Update:

Under Python 3.6 (I suspect the above timings were done using Python 2.x) and 2018 hardware (MacBook Pro), I now get the following timings:

% python -m timeit -s "import re" "re.match('hello', 'hello world')"
1000000 loops, best of 3: 0.661 usec per loop

% python -m timeit -s "import re; h=re.compile('hello')" "h.match('hello world')"
1000000 loops, best of 3: 0.285 usec per loop

% python -m timeit -s "import re" "h=re.compile('hello'); h.match('hello world')"
1000000 loops, best of 3: 0.65 usec per loop

% python --version
Python 3.6.5 :: Anaconda, Inc.

I also added a case (notice the quotation mark differences between the last two runs) that shows that re.match(x, ...) is literally [roughly] equivalent to re.compile(x).match(...), i.e. no behind-the-scenes caching of the compiled representation seems to happen.

the error explain all things, the idea is confused between gradle and maven.

try to create new project with two gradle modules, you can build spring application with gradle as maven.

see this example from spring guides

Try this:

 function GetDateFormat(controlName) {
        if ($('#' + controlName).val() != "") {      
            var d1 = Date.parse($('#' + controlName).val().toString().replace(/([0-9]+)\/([0-9]+)/,'$2/$1'));
            if (d1 == null) {
                alert('Date Invalid.');
                $('#' + controlName).val("");
            }
                var array = d1.toString('dd-MMM-yyyy');
                $('#' + controlName).val(array);
        }
    }

The RegExp replace .replace(/([0-9]+)\/([0-9]+)/,'$2/$1') change day/month position.

I like this solution (from the Matplotlib Plotting Cookbook):

import matplotlib.pyplot as plt
import matplotlib.ticker as ticker

x = [0,5,9,10,15]
y = [0,1,2,3,4]

tick_spacing = 1

fig, ax = plt.subplots(1,1)
ax.plot(x,y)
ax.xaxis.set_major_locator(ticker.MultipleLocator(tick_spacing))
plt.show()

This solution give you explicit control of the tick spacing via the number given to ticker.MultipleLocater(), allows automatic limit determination, and is easy to read later.

With the above answer, you cannot set the speed or have flexibility for customizing the text view functionality. To have your own scroll speed and flexibility to customize marquee properties, use the following:

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ellipsize="marquee"
    android:fadingEdge="horizontal"
    android:lines="1"
    android:id="@+id/myTextView"
    android:padding="4dp"
    android:scrollHorizontally="true"
    android:singleLine="true"
    android:text="Simple application that shows how to use marquee, with a long text" />

Within your activity:

private void setTranslation() {
        TranslateAnimation tanim = new TranslateAnimation(
                TranslateAnimation.ABSOLUTE, 1.0f * screenWidth,
                TranslateAnimation.ABSOLUTE, -1.0f * screenWidth,
                TranslateAnimation.ABSOLUTE, 0.0f,
                TranslateAnimation.ABSOLUTE, 0.0f);
        tanim.setDuration(1000);//set the duration
        tanim.setInterpolator(new LinearInterpolator());
        tanim.setRepeatCount(Animation.INFINITE);
        tanim.setRepeatMode(Animation.ABSOLUTE);

        textView.startAnimation(tanim);
    } 

I frankly would recommend the RazorGenerator nuget package. That way your views have a .designer.cs file generated when you save them and on top of getting compile time errors for you views, they are also precompiled into the assembly (= faster warmup) and Resharper provides some additional help as well.

To use this include the RazorGenerator nuget package in you ASP.NET MVC project and install the "Razor Generator" extension under item under Tools ? Extensions and Updates.

We use this and the overhead per compile with this approach is much less. On top of this I would probably recommend .NET Demon by RedGate which further reduces compile time impact substantially.

Hope this helps.

There are a few options

Short Syntax

Using the host : guest format you can do any of the following:

volumes:
  # Just specify a path and let the Engine create a volume
  - /var/lib/mysql

  # Specify an absolute path mapping
  - /opt/data:/var/lib/mysql

  # Path on the host, relative to the Compose file
  - ./cache:/tmp/cache

  # User-relative path
  - ~/configs:/etc/configs/:ro

  # Named volume
  - datavolume:/var/lib/mysql

Long Syntax

As of docker-compose v3.2 you can use long syntax which allows the configuration of additional fields that can be expressed in the short form such as mount type (volume, bind or tmpfs) and read_only.

version: "3.2"
services:
  web:
    image: nginx:alpine
    ports:
      - "80:80"
    volumes:
      - type: volume
        source: mydata
        target: /data
        volume:
          nocopy: true
      - type: bind
        source: ./static
        target: /opt/app/static

networks:
  webnet:

volumes:
  mydata:

Check out https://docs.docker.com/compose/compose-file/#long-syntax-3 for more info.

on the other side of the coin, you should use "non-char" regex that looks like this if special characters = allChars - number - ABC - space in your app context.

String regepx = "[^\\s\\w]*";

You already have several answers that suggest using JavaScript/jQuery. I am going to add an alternative that only uses HTML and CSS without any JS.

The basic idea is to use a set of radio buttons and labels (that will activate/deactivate the radio buttons), and with CSS control that only the label associated to the selected radio button will be displayed. If you want to allow selecting multiple values, you could achieve it by using checkboxes instead of radio buttons.

Here is an example. The code may be a bit messier (specially compared to the other solutions):

.select-sim {_x000D_
  width:200px;_x000D_
  height:22px;_x000D_
  line-height:22px;_x000D_
  vertical-align:middle;_x000D_
  position:relative;_x000D_
  background:white;_x000D_
  border:1px solid #ccc;_x000D_
  overflow:hidden;_x000D_
}_x000D_
_x000D_
.select-sim::after {_x000D_
  content:"?";_x000D_
  font-size:0.5em;_x000D_
  font-family:arial;_x000D_
  position:absolute;_x000D_

CROS needs to be resolved from server side.

Create Filters as per requirement to allow access and add filters in web.xml

Example using spring:

Filter Class:

@Component
public class SimpleFilter implements Filter {

@Override
public void init(FilterConfig arg0) throws ServletException {}

@Override
public void doFilter(ServletRequest req, ServletResponse resp,
                     FilterChain chain) throws IOException, ServletException {

    HttpServletResponse response=(HttpServletResponse) resp;

    response.setHeader("Access-Control-Allow-Origin", "*");
    response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
    response.setHeader("Access-Control-Max-Age", "3600");
    response.setHeader("Access-Control-Allow-Headers", "x-requested-with");

    chain.doFilter(req, resp);
}

@Override
public void destroy() {}

}

Web.xml:

<filter>
    <filter-name>simpleCORSFilter</filter-name>
    <filter-class>
        com.abc.web.controller.general.SimpleFilter
    </filter-class>
</filter>
<filter-mapping>
    <filter-name>simpleCORSFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

Unless I misunderstand your question, you can just open a file read only. Here is a simply example, without any checks.

To get the file path from the user use this function:

Private Function get_user_specified_filepath() As String
    'or use the other code example here.
    Dim fd As Office.FileDialog
    Set fd = Application.FileDialog(msoFileDialogFilePicker)
    fd.AllowMultiSelect = False
    fd.Title = "Please select the file."
    get_user_specified_filepath = fd.SelectedItems(1)
End Function

Then just open the file read only and assign it to a variable:

dim wb as workbook
set wb = Workbooks.Open(get_user_specified_filepath(), ReadOnly:=True)

Arrays.sort(numArray);
return (numArray[size/2] + numArray[(size-1)/2]) / 2;

Have you tried:

db.posts.find({"created_on": {"$gte": new Date(2012, 7, 14), "$lt": new Date(2012, 7, 15)}})

The problem you're going to run into is that dates are stored as timestamps in Mongo. So, to match a date you're asking it to match a timestamp. In your case I think you're trying to match a day (ie. from 00:00 to 23:59 on a specific date). If your dates are stored without times then you should be okay. Otherwise, try specifying your date as a range of time on the same day (ie. start=00:00, end=23:59) if gte doesn't work.

similar question

<input type="text" name="yourName" value="A new value" onfocus="if (this.value == 'A new value') this.value =='';" onblur="if (this.value=='') alert('Please enter a value');" />

Some JavaScript engines can parse that format directly, which makes the task pretty easy:

function convertDate(inputFormat) {_x000D_
  function pad(s) { return (s < 10) ? '0' + s : s; }_x000D_
  var d = new Date(inputFormat)_x000D_
  return [pad(d.getDate()), pad(d.getMonth()+1), d.getFullYear()].join('/')_x000D_
}_x000D_
_x000D_
console.log(convertDate('Mon Nov 19 13:29:40 2012')) // => "19/11/2012"

I asked the same question some time ago and had to answer it myself. Here's what I came up with:

It seems, my first thought [that it comes from its JavaScript roots] was correct.

'\/' === '/' in JavaScript, and JSON is valid JavaScript. However, why are the other ignored escapes (like \z) not allowed in JSON?

The key for this was reading http://www.cs.tut.fi/~jkorpela/www/revsol.html, followed by http://www.w3.org/TR/html4/appendix/notes.html#h-B.3.2. The feature of the slash escape allows JSON to be embedded in HTML (as SGML) and XML.

You can use Windows Containers inside a virtual machine (the guest OS should match the requirements - Windows 10 Pro or Windows 2016).

For example you can use VirtualBox, just enable Hyper-V inside System / Acceleration / Paravirtualization Interface.

After that if Docker doesn't start up because of an error, use the "Switch to Windows containers..." in the settings.

(this could be moved as a comment to the accepted answer, but I don't have enough reputation to do so)

Just escape the "\" by using + "\\Tasks" or use a verbatim string like @"\Tasks"

This has Changed again in Beta 5. Weee! It's now a method on CollectionType

Old:

var fullName = "First Last"
var fullNameArr = split(fullName) {$0 == " "}

New:

var fullName = "First Last"
var fullNameArr = fullName.split {$0 == " "}

Apples Release Notes

The reason for this is, that Google is sending an "X-Frame-Options: SAMEORIGIN" response header. This option prevents the browser from displaying iFrames that are not hosted on the same domain as the parent page.

See: Mozilla Developer Network - The X-Frame-Options response header

So, the concept of a "wildcard" in Regular Expressions works a bit differently. In order to match "any character" you would use "." The "*" modifier means, match any number of times.

It may be caused by IE's box model bug. To fix this, you can use the Box Model Hack.

I'd like to share my steps which is a bit different to what offered by rynop and superluminary.

• for A Record is exactly the same but
• instead of creating CNAME for www I would prefer to redirect it to my blank domain (non-www)

This configuration is referring to guidance of preferred domain. The domain setting of www to non www or vise versa can be different on each of the domain providers. Since my domain is under GoDaddy, so under the Domain Setting I set it using the Subdomain Forwarding (301).

As the result of pointing the domain to Github repository, it will then give all the URLs for both of master and gh-pages branch similar like the ones I listed below goes to the preferred domain:

master

By creating CNAME file on master branch (check it on my user repository).

http://hyipworld.github.io/
http://www.hyip.world/
http://hyip.world/

gh-pages

By creating the same CNAME file on gh-pages branch (check it on my project repository).

http://hyipworld.github.io/maps/
http://www.hyip.world/maps/
http://hyip.world/maps/

As addition to the CNAME file above, you may need to completely bypass Jekyll processing on GitHub Pages by creating a file named .nojekyll in the root of your pages repo.

Make sure you shouldn't have to open the MVC project like File->Open Web Site use File->Open Project instead.

The file I needed to update was ~/.profile.

However, I couldn't leave this question without recommending my favorite application, iTerm 2.

iTerm 2 lets you load global color schemes from a file. Really easy to experiment and try a bunch of color schemes.

Here's a screenshot of the iTerm 2 window and the color preferences.

Once I added the following to my ~/.profile file iTerm 2 was able to override the colors.

export CLICOLOR=1
export LSCOLORS=GxFxCxDxBxegedabagaced
export PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

Here is a great repository with some nice presets:

Bonus: Choose "Show/hide iTerm2 with a system-wide hotkey" and bind the key with BetterTouchTool for an instant hide/show the terminal with a mouse gesture.

This error arise from the fact that you are trying to define an object of shape (0,) as an object of shape (2,). If you append what you want without forcing it to be equal to result[0] there is no any issue:

b = np.append([result[0]], [1,2])

But when you define result[0] = b you are equating objects of different shapes, and you can not do this. What are you trying to do?

With PostgreSQL:

SELECT reltuples AS approximate_row_count FROM pg_class WHERE relname = 'table_name'

Using ES6 syntax in React does not bind this to user-defined functions however it will bind this to the component lifecycle methods.

So the function that you declared will not have the same context as the class and trying to access this will not give you what you are expecting.

For getting the context of class you have to bind the context of class to the function or use arrow functions.

Method 1 to bind the context:

class MyContainer extends Component {

    constructor(props) {
        super(props);
        this.onMove = this.onMove.bind(this);
        this.testVarible= "this is a test";
    }

    onMove() {
        console.log(this.testVarible);
    }
}

Method 2 to bind the context:

class MyContainer extends Component {

    constructor(props) {
        super(props);
        this.testVarible= "this is a test";
    }

    onMove = () => {
        console.log(this.testVarible);
    }
}

Method 2 is my preferred way but you are free to choose your own.

Update: You can also create the properties on class without constructor:

class MyContainer extends Component {

    testVarible= "this is a test";

    onMove = () => {
        console.log(this.testVarible);
    }
}

Note If you want to update the view as well, you should use state and setState method when you set or change the value.

Example:

class MyContainer extends Component {

    state = { testVarible: "this is a test" };

    onMove = () => {
        console.log(this.state.testVarible);
        this.setState({ testVarible: "new value" });
    }
}

To me, the antipathy towards var illustrates why bilingualism in .NET is important. To those C# programmers who have also done VB .NET, the advantages of var are intuitively obvious. The standard C# declaration of:

List<string> whatever = new List<string>();

is the equivalent, in VB .NET, of typing this:

Dim whatever As List(Of String) = New List(Of String)

Nobody does that in VB .NET, though. It would be silly to, because since the first version of .NET you've been able to do this...

Dim whatever As New List(Of String)

...which creates the variable and initializes it all in one reasonably compact line. Ah, but what if you want an IList<string>, not a List<string>? Well, in VB .NET that means you have to do this:

Dim whatever As IList(Of String) = New List(Of String)

Just like you'd have to do in C#, and obviously couldn't use var for:

IList<string> whatever = new List<string>();

If you need the type to be something different, it can be. But one of the basic principles of good programming is reducing redundancy, and that's exactly what var does.

I'm the creator of Restangular.

You can take a look at this CRUD example to see how you can PUT/POST/GET elements without all that URL configuration and $resource configuration that you need to do. Besides it, you can then use nested resources without any configuration :).

Check out this plunkr example:

http://plnkr.co/edit/d6yDka?p=preview

You could also see the README and check the documentation here https://github.com/mgonto/restangular

If you need some feature that's not there, just create an issue. I usually add features asked within a week, as I also use this library for all my AngularJS projects :)

Hope it helps!

Use the -L option to follow redirects:

While you can't kill all open connections with a single command, you can create a set of queries to do that for you if there are too many to do by hand.

This example will create a series of KILL <pid>; queries for all some_user's connections from 192.168.1.1 to my_db.

SELECT 
CONCAT('KILL ', id, ';') 
FROM INFORMATION_SCHEMA.PROCESSLIST 
WHERE `User` = 'some_user' 
AND `Host` = '192.168.1.1';
AND `db` = 'my_db';

In hibernate.cfg.xml , please put following code

XSD:
XSD (XML Schema Definition) specifies how to formally describe the elements in an Extensible Markup Language (XML) document.
Xml:
XML was designed to describe data.It is independent from software as well as hardware.
It enhances the following things.
-Data sharing.
-Platform independent.
-Increasing the availability of Data.

Differences:

1. XSD is based and written on XML.

2. XSD defines elements and structures that can appear in the document, while XML does not.

3. XSD ensures that the data is properly interpreted, while XML does not.

4. An XSD document is validated as XML, but the opposite may not always be true.

5. XSD is better at catching errors than XML.

An XSD defines elements that can be used in the documents, relating to the actual data with which it is to be encoded.
for eg:
A date that is expressed as 1/12/2010 can either mean January 12 or December 1st. Declaring a date data type in an XSD document, ensures that it follows the format dictated by XSD.

You may also try mongoosejs's lean() :

UserModel.find().lean().exec(function (err, users) {
    return res.end(JSON.stringify(users));
}

You are asking for the condition where all the conditions are true, so len of the frame is the answer, unless I misunderstand what you are asking

In [17]: df = DataFrame(randn(20,4),columns=list('ABCD'))

In [18]: df[(df['A']>0) & (df['B']>0) & (df['C']>0)]

The Go reflection package has methods for inspecting the type of variables.

The following snippet will print out the reflection type of a string, integer and float.

package main

import (
    "fmt"
    "reflect"
)

func main() {

    tst := "string"
    tst2 := 10
    tst3 := 1.2

    fmt.Println(reflect.TypeOf(tst))
    fmt.Println(reflect.TypeOf(tst2))
    fmt.Println(reflect.TypeOf(tst3))

}

Output:

Hello, playground
string
int
float64

see: http://play.golang.org/p/XQMcUVsOja to view it in action.

I agree with Mutanos and Alecio. Further, one can check as many identical method calls as possible (verifying the subsequent calls in the production code, the order of the verify's does not matter). Here is the code:

import static org.mockito.AdditionalMatchers.*;

    verify(mockObject).myMethod(aryEq(new byte[] { 0 }));
    verify(mockObject).myMethod(aryEq(new byte[] { 1, 2 }));

timespec_get from C11 returns up to nanoseconds, rounded to the resolution of the implementation.

#include <time.h>
struct timespec ts;
timespec_get(&ts, TIME_UTC);
struct timespec {
    time_t   tv_sec;        /* seconds */
    long     tv_nsec;       /* nanoseconds */
};

When interviewing recently, I was often asked to implement a data structure, usually LinkedList or HashMap. Both of these are easy enough to be doable in a short time, and difficult enough to eliminate the clueless.

create model.ts in your component directory as below

export module DataModel {
       export interface DataObjectName {
         propertyName: type;
        }
       export interface DataObjectAnother {
         propertyName: type;
        }
    }

then in your component import above as, import {DataModel} from './model';

export class YourComponent {
   public DataObject: DataModel.DataObjectName;
}

your DataObject should have all the properties from DataObjectName.

I realise this is an old post, but just in case anyone else is looking, you can use Contains by providing the case insensitive string equality comparer like so:

using System.Linq;

// ...

if (testList.Contains(keyword, StringComparer.OrdinalIgnoreCase))
{
    Console.WriteLine("Keyword Exists");
}

This has been available since .net 2.0 according to msdn.

as well as ... 1/ substituted the "ffile" with just "file" 2/ all the above variations with the http:// prefixed before the ffile or file.

The best I could see was there is a possibility that if one wanted to open (edit) or save the file, it could be accomplished. However, the exec file would not execute otherwise.

I'd have put this in as a comment as I'm really not certain that this is likely to be the case, but as I recall it doesn't a try/except statement involve a modification to the way the garbage disposal mechanism of the compiler works, in that it clears up object memory allocations in a recursive way off the stack. There may not be an object to be cleared up in this case or the for loop may constitute a closure that the garbage collection mechanism recognises sufficient to enforce a different collection method. Probably not, but I thought it worth a mention as I hadn't seen it discussed anywhere else.

A datetime.timedelta corresponds to the difference between two dates, not a date itself. It's only expressed in terms of days, seconds, and microseconds, since larger time units like months and years don't decompose cleanly (is 30 days 1 month or 0.9677 months?).

If you want to convert a timedelta into hours and minutes, you can use the total_seconds() method to get the total number of seconds and then do some math:

x = datetime.timedelta(1, 5, 41038)  # Interval of 1 day and 5.41038 seconds
secs = x.total_seconds()
hours = int(secs / 3600)
minutes = int(secs / 60) % 60

use Date function directly. Hope it works

To "loop" and take advantage of Spark's parallel computation framework, you could define a custom function and use map.

def customFunction(row):

   return (row.name, row.age, row.city)

sample2 = sample.rdd.map(customFunction)

or

sample2 = sample.rdd.map(lambda x: (x.name, x.age, x.city))

The custom function would then be applied to every row of the dataframe. Note that sample2 will be a RDD, not a dataframe.

Map may be needed if you are going to perform more complex computations. If you just need to add a simple derived column, you can use the withColumn, with returns a dataframe.

sample3 = sample.withColumn('age2', sample.age + 2)

You can do this by adding a div i.e. centerBlock. And give this property in CSS to center the image or any content. Here is the code:

<div class="container">
    <div class="row">
        <div class="col-sm-4 col-md-4 col-lg-4">
            <div class="centerBlock">
                <img class="img-responsive" src="img/some-image.png" title="This image needs to be centered">
            </div>
        </div>
        <div class="col-sm-8 col-md-8 col-lg-8">
            Some content not important at this moment
        </div>
    </div>
</div>


// CSS

.centerBlock {
  display: table;
  margin: auto;
}

For case when your interval's end it's date without hours like "from 2017-01-01 to whole day of 2017-01-16" it's better to adjust interval's to 23 hours 59 minutes and 59 seconds like:

end = end.Add(time.Duration(23*time.Hour) + time.Duration(59*time.Minute) + time.Duration(59*time.Second)) 

if now.After(start) && now.Before(end) {
    ...
}

If you can use numpy, then you can delete multiple indices:

>>> import numpy as np
>>> a = np.arange(10)
>>> np.delete(a,(1,3,5))
array([0, 2, 4, 6, 7, 8, 9])

and if you use np.r_ you can combine slices with individual indices:

>>> np.delete(a,(np.r_[0:5,7,9]))
array([5, 6, 8])

However, the deletion is not in place, so you have to assign to it.

It's rare to see the difference nowadays because html 5 don't support framesets anymore. But back at the time we have frameset, document.location would redirect only the frame in which code is being executed, and window.location would redirect the entire page.

Don't give up. Linux can do it with the right hardware, via "USB Gadgets." And giving the following facts:

1. My old Nokia N95 could use it's USB to be a "Mass Storage Device", a "Media Player", "a GSM modem", or to print photos.
2. I can plug an iPhone into an iPad via a the Apple USB-Camera passive adapter, and they transfer pictures.
3. iPhone can obvious present as a number of things, e.g. when they go into DFU.

Why is all this relevant?

Because if I was writing a linux phone I know what it would do, and how it would do it. And the answer would involve USB Gadgets.

Reading one of the links that was posted here,

It's the Linux kernel, the code is in drivers/usb/gadget/ in the kernel.org tree if you are interested. Android does have a few specific gadget patches that are not in mainline, but it's not all that much. You can see all of this by just checking out their kernel git tree, no need to bother their developers.

I would guess that you would have a shot at it - but it would involve recompiling the android kernel/operating system - or at least having a build environment in which you /could/ rebuild the kernel if you wanted.

BTW, I have an Atmel NGW100mkII, which support USB gadgets, but doesn't ship with the HID module. And I'll be having to do the above and more.

If it is for your testing. You can use adb commands.

adb shell pm clear <package name>

MSDN has an outline of the purpose of the global.asax file.

Effectively, global.asax allows you to write code that runs in response to "system level" events, such as the application starting, a session ending, an application error occuring, without having to try and shoe-horn that code into each and every page of your site.

You can use it by by choosing Add > New Item > Global Application Class in Visual Studio. Once you've added the file, you can add code under any of the events that are listed (and created by default, at least in Visual Studio 2008):

• Application_Start
• Application_End
• Session_Start
• Session_End
• Application_BeginRequest
• Application_AuthenticateRequest
• Application_Error

There are other events that you can also hook into, such as "LogRequest".

You can send intent MASTER_CLEAR in adb:

adb shell am broadcast -a android.intent.action.MASTER_CLEAR

or as root

adb shell  "su -c 'am broadcast -a android.intent.action.MASTER_CLEAR'"

Your nav div is actually centered correctly. But the ul inside is not. Give the ul a specific width and center that as well.

Markus raised a great point. I decided to look up the autocomplete attribute and got the following:

The only downside to using this attribute is that it is not standard (it works in IE and Mozilla browsers), and would cause XHTML validation to fail. I think this is a case where it's reasonable to break validation however. (source)

So I would have to say that although it doesn't work 100% across the board it is handled in the major browsers so its a great solution.

You should use TryParse - Parse throws an exception if the string is not a valid number - e.g. if you want to test for a valid integer:

int v;
if (Int32.TryParse(textMyText.Text.Trim(), out v)) {
  . . .
}

If you want to test for a valid floating-point number:

double v;
if (Double.TryParse(textMyText.Text.Trim(), out v)) {
  . . .
}

Note also that Double.TryParse has an overloaded version with extra parameters specifying various rules and options controlling the parsing process - e.g. localization ('.' or ',') - see http://msdn.microsoft.com/en-us/library/3s27fasw.aspx.

You can open the file again using vi helloworld.txt and then use cat /path/your_file to view it.

Although very late, hope it still helps someone:

Many of comments here and in other posts are concerned about setting initial size.

I used jqueryUi.Resizable. Initial widths shall be defined within each "< td >" tag at first line (< TR >). This is unlike what colResizable recommends; colResizable prohibits defining widths at first line, there I had to define widths in "< col>" tag which wasn't consikstent with jqueryresizable.

the following snippet is very neat and easier to read than usual samples:

$("#Content td").resizable({
    handles: "e, s",
    resize: function (event, ui) {
        var sizerID = "#" + $(event.target).attr("id");
        $(sizerID).width(ui.size.width);
    }
});

Content is id of my table. Handles (e, s) define in which directions the plugin can change the size. You must have a link to css of jquery-ui, otherwise it won't work.

You can use backslash either way;

string str = "He said to me, \"Hello World\". How are you?";

It prints;

He said to me, "Hello World". How are you?

which is exactly same prints with;

string str = @"He said to me, ""Hello World"". How are you?";

Here is a DEMO.

" is still part of your string.

This is my implementation of RotatableImageView. Usage is very easy: just copy attrs.xml and RotatableImageView.java into your project and add RotatableImageView to your layout. Set desired rotation angle using example:angle parameter.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:example="http://schemas.android.com/apk/res/com.example"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <com.example.views.RotatableImageView
        android:id="@+id/layout_example_image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true"
        android:scaleType="fitCenter"
        android:src="@drawable/ic_layout_arrow"
        example:angle="180" />
</FrameLayout>

If you have some problems with displaying image, try change code in RotatableImageView.onDraw() method or use draw() method instead.

The newest version of the Anaconda installer for Windows will also install a windows launcher for "Anaconda Prompt" and "Anaconda Powershell Prompt". If you use one of those instead of the regular windows cmd shell, the conda command, python etc. should be available by default in this shell.

If you are using Ubuntu 18.04 or higher with python3.xxx then try this command

$ sudo apt install python3-sklearn 

then try your command. hope it will work

To adjust the size of one figure:

import matplotlib.pyplot as plt

fig=plt.figure(figsize=(15, 15))

To change the default settings, and therefore all your plots:

import matplotlib.pyplot as plt

plt.rcParams['figure.figsize'] = [15, 15]

You need to specify it on the methods that can throw the exceptions. You just seperate them with a ',' if it can throw more than 1 type of exception. e.g.

public interface MyInterface {
  public MyObject find(int x) throws MyExceptionA,MyExceptionB;
}

The URL is relative to the location of the CSS file, so this should work for you:

url('../../images/image.jpg')

The relative URL goes two folders back, and then to the images folder - it should work for both cases, as long as the structure is the same.

From https://www.w3.org/TR/CSS1/#url:

Partial URLs are interpreted relative to the source of the style sheet, not relative to the document

It is cd for "current directory".

I would recommend the rename command for this. Type ren /? at the command line for more help.

You can have a constructor in the abstract class that accepts the init parameters. The Java spec only specifies that the anonymous class, which is the offspring of the (optionally) abstract class or implementation of an interface, can not have a constructor by her own right.

The following is absolutely legal and possible:

static abstract class Q{
    int z;
    Q(int z){ this.z=z;}
    void h(){
        Q me = new Q(1) {
        };
    }
}

If you have the possibility to write the abstract class yourself, put such a constructor there and use fluent API where there is no better solution. You can this way override the constructor of your original class creating an named sibling class with a constructor with parameters and use that to instantiate your anonymous class.

Here's an example of how you would accomplish such a task:

#import <Foundation/Foundation.h>
typedef int (^IntBlock)();

@interface myobj : NSObject
{
    IntBlock compare;
}

@property(readwrite, copy) IntBlock compare;

@end

@implementation myobj

@synthesize compare;

- (void)dealloc 
{
   // need to release the block since the property was declared copy. (for heap
   // allocated blocks this prevents a potential leak, for compiler-optimized 
   // stack blocks it is a no-op)
   // Note that for ARC, this is unnecessary, as with all properties, the memory management is handled for you.
   [compare release];
   [super dealloc];
}
@end

int main () {
    @autoreleasepool {
        myobj *ob = [[myobj alloc] init];
        ob.compare = ^
        {
            return rand();
        };
        NSLog(@"%i", ob.compare());
        // if not ARC
        [ob release];
    }

    return 0;
}

Now, the only thing that would need to change if you needed to change the type of compare would be the typedef int (^IntBlock)(). If you need to pass two objects to it, change it to this: typedef int (^IntBlock)(id, id), and change your block to:

^ (id obj1, id obj2)
{
    return rand();
};

I hope this helps.

EDIT March 12, 2012:

For ARC, there are no specific changes required, as ARC will manage the blocks for you as long as they are defined as copy. You do not need to set the property to nil in your destructor, either.

Just for completion, here is a code example indicating the differences:

success \ error:

$http.get('/someURL')
.success(function(data, status, header, config) {
    // success handler
})
.error(function(data, status, header, config) {
    // error handler
});

then:

$http.get('/someURL')
.then(function(response) {
    // success handler
}, function(response) {
    // error handler
})
.then(function(response) {
    // success handler
}, function(response) {
    // error handler
})
.then(function(response) {
    // success handler
}, function(response) {
    // error handler
}).

with this globals variables idea, I saved MainActivity instance in onCreate(); Android global variable

public class ApplicationController extends Application {

    public static MainActivity this_MainActivity;
}

and Open dialog like this. it worked.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Global Var
    globals = (ApplicationController) this.getApplication();
    globals.this_MainActivity = this;
}

and in a thread, I open dialog like this.

AlertDialog.Builder alert = new AlertDialog.Builder(globals.this_MainActivity);

1. Open MainActivity
2. Start a thread.
3. Open dialog from thread -> work.
4. Click "Back button" ( onCreate will be called and remove first MainActivity)
5. New MainActivity will start. ( and save it's instance to globals )
6. Open dialog from first thread --> it will open and work.

This is a massively late reply, but I think useful for future reference. Rather than write your own math parser (although the pyparsing example above is great) you could use SymPy. I don't have a lot of experience with it, but it contains a much more powerful math engine than anyone is likely to write for a specific application and the basic expression evaluation is very easy:

>>> import sympy
>>> x, y, z = sympy.symbols('x y z')
>>> sympy.sympify("x**3 + sin(y)").evalf(subs={x:1, y:-3})
0.858879991940133

Very cool indeed! A from sympy import * brings in a lot more function support, such as trig functions, special functions, etc., but I've avoided that here to show what's coming from where.

I got this error, while I was creating a new database on my MongoDb Compass Community. The issue was with my Mongod, it was not running. So as a fix, I had to run the Mongod command as preceding.

C:\Program Files\MongoDB\Server\3.6\bin>mongod

I was able to create a database after running that command.

For disabling Hibernate:select message in log, it is possible to set the property into HibernateJpaVendorAdapter:

Let the modern java.time classes of JSR 310 automatically generate localized text, rather than hard-coding 12-hour clock and AM/PM.

LocalTime                                     // Represent a time-of-day, without date, without time zone or offset-from-UTC.
.now(                                         // Capture the current time-of-day as seen in a particular time zone.
    ZoneId.of( "Africa/Casablanca" )          
)                                             // Returns a `LocalTime` object.
.format(                                      // Generate text representing the value in our `LocalTime` object.
    DateTimeFormatter                         // Class responsible for generating text representing the value of a java.time object.
    .ofLocalizedTime(                         // Automatically localize the text being generated.
        FormatStyle.SHORT                     // Specify how long or abbreviated the generated text should be.
    )                                         // Returns a `DateTimeFormatter` object.
    .withLocale( Locale.US )                  // Specifies a particular locale for the `DateTimeFormatter` rather than rely on the JVM’s current default locale. Returns another separate `DateTimeFormatter` object rather than altering the first, per immutable objects pattern.
)                                             // Returns a `String` object.

Automatically localize

Rather than insisting on 12-hour clock with AM/PM, you may want to let java.time automatically localize for you. Call DateTimeFormatter.ofLocalizedTime.

To localize, specify:

• FormatStyle to determine how long or abbreviated should the string be.
• Locale to determine:
  • The human language for translation of name of day, name of month, and such.
  • The cultural norms deciding issues of abbreviation, capitalization, punctuation, separators, and such.

Here we get the current time-of-day as seen in a particular time zone. Then we generate text to represent that time. We localize to French language in Canada culture, then English language in US culture.

ZoneId z = ZoneId.of( "Asia/Tokyo" ) ;
LocalTime localTime = LocalTime.now( z ) ;

// Québec
Locale locale_fr_CA = Locale.CANADA_FRENCH ;  // Or `Locale.US`, and so on.
DateTimeFormatter formatterQuébec = DateTimeFormatter.ofLocalizedTime( FormatStyle.SHORT ).withLocale( locale_fr_CA ) ;
String outputQuébec = localTime.format( formatterQuébec ) ;

System.out.println( outputQuébec ) ;

// US
Locale locale_en_US = Locale.US ;  
DateTimeFormatter formatterUS = DateTimeFormatter.ofLocalizedTime( FormatStyle.SHORT ).withLocale( locale_en_US ) ;
String outputUS = localTime.format( formatterUS ) ;

System.out.println( outputUS ) ;

In the worst case - create the project once again with all the imports from the beginning. In my case none of the other options worked. This type of error hints that there is an error in the project settings. I once managed to solve it, but once further developments were done, the error came back. Recreating everything from the beginning helped me understand and optimize some links, and now I am confident it works correctly.

The semantics of setTimeout are roughly the same as in a web browser: the timeout arg is a minimum number of ms to wait before executing, not a guarantee. Furthermore, passing 0, a non-number, or a negative number, will cause it to wait a minimum number of ms. In Node, this is 1ms, but in browsers it can be as much as 50ms.

The reason for this is that there is no preemption of JavaScript by JavaScript. Consider this example:

setTimeout(function () {
  console.log('boo')
}, 100)
var end = Date.now() + 5000
while (Date.now() < end) ;
console.log('imma let you finish but blocking the event loop is the best bug of all TIME')

The flow here is:

1. schedule the timeout for 100ms.
2. busywait for 5000ms.
3. return to the event loop. check for pending timers and execute.

If this was not the case, then you could have one bit of JavaScript "interrupt" another. We'd have to set up mutexes and semaphors and such, to prevent code like this from being extremely hard to reason about:

var a = 100;
setTimeout(function () {
  a = 0;
}, 0);
var b = a; // 100 or 0?

The single-threadedness of Node's JavaScript execution makes it much simpler to work with than most other styles of concurrency. Of course, the trade-off is that it's possible for a badly-behaved part of the program to block the whole thing with an infinite loop.

Is this a better demon to battle than the complexity of preemption? That depends.

If you were only interested in 'z', you could create a function-based index.

CREATE INDEX users_z_idx ON users (INSTR(last_name,'z'))

Then your query would use WHERE INSTR(last_name,'z') > 0.

With this approach you would have to create a separate index for each character you might want to search for. I suppose if this is something you do often, it might be worth creating one index for each letter.

Also, keep in mind that if your data has the names capitalized in the standard way (e.g., "Zaxxon"), then both your example and mine would not match names that begin with a Z. You can correct for this by including LOWER in the search expression: INSTR(LOWER(last_name),'z').

Depends on what you want to do:

to read the value as an ascii code, you can write

char a = 'a';
int ia = (int)a; 
/* note that the int cast is not necessary -- int ia = a would suffice */

to convert the character '0' -> 0, '1' -> 1, etc, you can write

char a = '4';
int ia = a - '0';
/* check here if ia is bounded by 0 and 9 */

Explanation:
a - '0' is equivalent to ((int)a) - ((int)'0'), which means the ascii values of the characters are subtracted from each other. Since 0 comes directly before 1 in the ascii table (and so on until 9), the difference between the two gives the number that the character a represents.

puts false or true --> prints: false

puts false || true --> prints: true

Both choices refer to what algorithm the identity provider uses to sign the JWT. Signing is a cryptographic operation that generates a "signature" (part of the JWT) that the recipient of the token can validate to ensure that the token has not been tampered with.

• RS256 (RSA Signature with SHA-256) is an asymmetric algorithm, and it uses a public/private key pair: the identity provider has a private (secret) key used to generate the signature, and the consumer of the JWT gets a public key to validate the signature. Since the public key, as opposed to the private key, doesn't need to be kept secured, most identity providers make it easily available for consumers to obtain and use (usually through a metadata URL).

• HS256 (HMAC with SHA-256), on the other hand, involves a combination of a hashing function and one (secret) key that is shared between the two parties used to generate the hash that will serve as the signature. Since the same key is used both to generate the signature and to validate it, care must be taken to ensure that the key is not compromised.

If you will be developing the application consuming the JWTs, you can safely use HS256, because you will have control on who uses the secret keys. If, on the other hand, you don't have control over the client, or you have no way of securing a secret key, RS256 will be a better fit, since the consumer only needs to know the public (shared) key.

Since the public key is usually made available from metadata endpoints, clients can be programmed to retrieve the public key automatically. If this is the case (as it is with the .Net Core libraries), you will have less work to do on configuration (the libraries will fetch the public key from the server). Symmetric keys, on the other hand, need to be exchanged out of band (ensuring a secure communication channel), and manually updated if there is a signing key rollover.

Auth0 provides metadata endpoints for the OIDC, SAML and WS-Fed protocols, where the public keys can be retrieved. You can see those endpoints under the "Advanced Settings" of a client.

The OIDC metadata endpoint, for example, takes the form of https://{account domain}/.well-known/openid-configuration. If you browse to that URL, you will see a JSON object with a reference to https://{account domain}/.well-known/jwks.json, which contains the public key (or keys) of the account.

If you look at the RS256 samples, you will see that you don't need to configure the public key anywhere: it's retrieved automatically by the framework.

I find lambda useful for a list of functions that do the same, but for different circumstances.

Like the Mozilla plural rules:

plural_rules = [
    lambda n: 'all',
    lambda n: 'singular' if n == 1 else 'plural',
    lambda n: 'singular' if 0 <= n <= 1 else 'plural',
    ...
]
# Call plural rule #1 with argument 4 to find out which sentence form to use.
plural_rule[1](4) # returns 'plural'

If you'd have to define a function for all of those you'd go mad by the end of it.
Also, it wouldn't be nice with function names like plural_rule_1, plural_rule_2, etc. And you'd need to eval() it when you're depending on a variable function id.

This is for react-native, but login will work for all types.

isTokenExpired = async () => {
    try {
        const LoginTokenValue = await AsyncStorage.getItem('LoginTokenValue');
        if (JSON.parse(LoginTokenValue).RememberMe) {
            const { exp } = JwtDecode(LoginTokenValue);
            if (exp < (new Date().getTime() + 1) / 1000) {
                this.handleSetTimeout();
                return false;
            } else {
                //Navigate inside the application
                return true;
            }
        } else {
            //Navigate to the login page
        }
    } catch (err) {
        console.log('Spalsh -> isTokenExpired -> err', err);
        //Navigate to the login page
        return false;
    }
}

With dplyr 0.7.2, you can use the very useful case_when function :

x=read.table(
 text="V1 V2 V3 V4
 1  1  2  3  5
 2  2  4  4  1
 3  1  4  1  1
 4  4  5  1  3
 5  5  5  5  4")
x$V5 = case_when(x$V1==1 & x$V2!=4 ~ 1,
                 x$V2==4 & x$V3!=1 ~ 2,
                 TRUE ~ 0)

Expressed with dplyr::mutate, it gives:

x = x %>% mutate(
     V5 = case_when(
         V1==1 & V2!=4 ~ 1,
         V2==4 & V3!=1 ~ 2,
         TRUE ~ 0
     )
)

Please note that NA are not treated specially, as it can be misleading. The function will return NA only when no condition is matched. If you put a line with TRUE ~ ..., like I did in my example, the return value will then never be NA.

Therefore, you have to expressively tell case_when to put NA where it belongs by adding a statement like is.na(x$V1) | is.na(x$V3) ~ NA_integer_. Hint: the dplyr::coalesce() function can be really useful here sometimes!

Moreover, please note that NA alone will usually not work, you have to put special NA values : NA_integer_, NA_character_ or NA_real_.

Right click the solution explorer and choose the add reference.one dialog box will be appear. On that select (.net)-> System.windows.form. Imports System.Windows.Forms (vb) and using System.windows.forms(C#) copy this in your coding and then write messagebox.show("").

Using mysql command

$ echo "select datediff('2013-06-20 18:12:54+08:00', '2013-05-30 18:12:54+08:00');"  | mysql -N

Result: 21

NOTE: Only the date parts of the values are used in the calculation

public static class Employee
{
    public static string SomeSetting
    {
        get 
        {
            return ConfigurationManager.AppSettings["SomeSetting"];    
        }
    }
}

Declare the property as static, as well. Also, Don't bother storing a private reference to ConfigurationManager.AppSettings. ConfigurationManager is already a static class.

If you feel that you must store a reference to appsettings, try

public static class Employee
{
    private static NameValueCollection _appSettings=ConfigurationManager.AppSettings;

    public static NameValueCollection AppSettings { get { return _appSettings; } }

}

It's good form to always give an explicit access specifier (private, public, etc) even though the default is private.

    # Simple implementation of the didSelectRowAt function.

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
         print("row selection: \(indexPath.row)")
    }

I was able to update the user settings.json

On my mac it was stored in:

~/Library/Application Support/Code/User/settings.json

Within it, I set the following:

{
    "python.linting.pycodestyleEnabled": true,
    "python.linting.pylintEnabled": true,
    "python.linting.pylintPath": "pylint",
    "python.linting.pylintArgs": ["--load-plugins", "pylint_django"]
}

That solved the issue for me.
