In general one could,

merge_list <- function(...) by(v<-unlist(c(...)),names(v),base::c)

Note that the by() solution returns an attributed list, so it will print differently, but will still be a list. But you can get rid of the attributes with attr(x,"_attribute.name_")<-NULL. You can probably also use aggregate().

I will post my answer here since it's the first result in google's search

1) react-native unlink <Module Name>

2) npm unlink <Module Name>

3) npm uninstall --save <Module name

A perfect easy way

var data = {
    'PropertyA': 1,
    'PropertyB': 2,
    'PropertyC': 3
};

var newProperty = 'getThisFromUser';
data[newProperty] = 4;

console.log(data);

If you want to apply it on an array of data (ES6/TS version)

const data = [
  { 'PropertyA': 1, 'PropertyB': 2, 'PropertyC': 3 },
  { 'PropertyA': 11, 'PropertyB': 22, 'PropertyC': 33 }
];

const newProperty = 'getThisFromUser';
data.map( (d) => d[newProperty] = 4 );

console.log(data);

auto keyword is intended to use in such situation, it is absolutely safe. But unfortunately it available only in C++0x so you will have portability issues with it.

Your struct can have methods and properties... why not try

public struct MyStruct { 
    public string s;
    public int length { return s.Length; }
}

Correction @Guffa's answer shows that it is possible... more info here: http://www.codeproject.com/KB/cs/Csharp_implicit_operator.aspx

If you're willing to give up a hint of abstraction, then you could use a custom wrapper class which simply passes everything through to the PDO. Say, something like this: (Warning, code untested)

class SQLitePDOWrapper
{
    private $pdo;

    public function __construct( $dns, $uname = null, $pwd = null, $opts = null )
    {
        $this->pdo = new PDO( $dns, $unam, $pwd, $opts ); 
    }
    public function __call( $nm, $args )
    {
        $ret = call_user_func_array( array( $this->pdo, $nm ), $args );
        if( $ret instanceof PDOStatement )
        {
            return new StatementWrapper( $this, $ret, $args[ 0 ] ); 
               // I'm pretty sure args[ 0 ] will always be your query, 
               // even when binding
        }

        return $ret;
    }

}

class StatementWrapper
{
    private $pdo; private $stat; private $query;

    public function __construct( PDO $pdo, PDOStatement $stat, $query )
    {
        $this->pdo  = $pdo;
        $this->stat = $stat;
        this->query = $query;
    }

    public function rowCount()
    {
        if( strtolower( substr( $this->query, 0, 6 ) ) == 'select' )
        {
            // replace the select columns with a simple 'count(*)
            $res = $this->pdo->query( 
                     'SELECT COUNT(*)' . 
                          substr( $this->query, 
                              strpos( strtolower( $this->query ), 'from' ) ) 
                   )->fetch( PDO::FETCH_NUM );
            return $res[ 0 ];
        }
        return $this->stat->rowCount();
    }

    public function __call( $nm, $args )
    {
        return call_user_func_array( array( $this->stat, $nm ), $args );
    }
}

Instead of coding all the constrains you could use a subclass that handles .intrinsicContentSize of UIView class in a simpler way. This solution improves also Interface Builder a little in a way to support with "intrinsicWidth" and "intrinsicHeight" of views. While you could extend UIView's and have those properties available on all UIViews in IB its cleaner to subclass.

// IntrinsicView.h
@import UIKit

IB_DESIGNABLE
@interface IntrinsicView : UIView
-(instancetype)initWithFrame:(CGRect)rect;
@property IBInspectable CGSize intrinsic;
@end

// IntrinsicView.m
#import "IntrinsicView.h"

@implementation IntrinsicView {
    CGSize _intrinsic;
}
- (instancetype)initWithFrame:(CGRect)frame {
    _intrinsic = frame.size;
    if ( !(self = [super initWithFrame:frame]) ) return nil;
    // your stuff here..
    return self;
}
-(CGSize)intrinsicContentSize {
    return _intrinsic;
}
-(void)prepareForInterfaceBuilder {
    self.frame = CGRectMake(self.frame.origin.x, self.frame.origin.y, _intrinsic.width,_intrinsic.height);
}
@end

Which means you can just allocate those IntrinsicView's and the self.frame.size is taken as intrinsicContentSize. That way it does not disturb the normal layout and you dont need to set constraint relations that don't even apply in full with UIStackViews

#import "IntrinsicView.h"

- (void)viewDidLoad {
    [super viewDidLoad];
    
    UIStackView *column = [[UIStackView alloc] initWithFrame:self.view.frame];
    column.spacing = 2;
    column.alignment = UIStackViewAlignmentFill;
    column.axis = UILayoutConstraintAxisVertical; //Up-Down
    column.distribution = UIStackViewDistributionFillEqually;
    
    for (int row=0; row<5; row++) {
        //..frame:(CGRect) defines here proportions and
        //relation to axis of StackView
        IntrinsicView *intrinsicView = [[IntrinsicView alloc] initWithFrame:CGRectMake(0, 0, 30.0, 30.0)];
        
        [column addArrangedSubview:intrinsicView];
    }
    [self.view addSubview:column];
}

now you can go crazy with UIStackView's

or in swift + encoding, decoding, IB support, Objective-C support

@IBDesignable @objc class IntrinsicView : UIView {
    @IBInspectable var intrinsic : CGSize
    @objc override init(frame: CGRect) {
        intrinsic = frame.size
        super.init(frame: frame)
    }
    required init?(coder: NSCoder) {
        intrinsic = coder.decodeCGSize(forKey: "intrinsic")
        super.init(coder: coder)
    }
    override func encode(with coder: NSCoder) {
        coder.encode(intrinsic, forKey: "intrinsic")
        super.encode(with: coder)
    }
    override var intrinsicContentSize: CGSize {
        return intrinsic
    }
    override func prepareForInterfaceBuilder() {
        frame = CGRect(x: self.frame.origin.x, y: self.frame.origin.y, width: intrinsic.width, height: intrinsic.height)
    }
}

Bitcode is a new feature of iOS 9

Bitcode is an intermediate representation of a compiled program. Apps you upload to iTunes Connect that contain bitcode will be compiled and linked on the App Store. Including bitcode will allow Apple to re-optimize your app binary in the future without the need to submit a new version of your app to the store.

Note: For iOS apps, bitcode is the default, but optional. If you provide bitcode, all apps and frameworks in the app bundle need to include bitcode. For watchOS apps, bitcode is required

So you should disabled bitcode until all the frameworks of your app have bitcode enabled.

.NET 4.0 and above:

using System.Web.Security.AntiXss;
//...
var encoded = AntiXssEncoder.HtmlEncode("input", useNamedEntities: true);

The issue with the "one thread per request" model for a server is that they don't scale well for several scenarios compared to the event loop thread model.

Typically, in I/O intensive scenarios the requests spend most of the time waiting for I/O to complete. During this time, in the "one thread per request" model, the resources linked to the thread (such as memory) are unused and memory is the limiting factor. In the event loop model, the loop thread selects the next event (I/O finished) to handle. So the thread is always busy (if you program it correctly of course).

The event loop model as all new things seems shiny and the solution for all issues but which model to use will depend on the scenario you need to tackle. If you have an intensive I/O scenario (like a proxy), the event base model will rule, whereas a CPU intensive scenario with a low number of concurrent processes will work best with the thread-based model.

In the real world most of the scenarios will be a bit in the middle. You will need to balance the real need for scalability with the development complexity to find the correct architecture (e.g. have an event base front-end that delegates to the backend for the CPU intensive tasks. The front end will use little resources waiting for the task result.) As with any distributed system it requires some effort to make it work.

If you are looking for the silver bullet that will fit with any scenario without any effort, you will end up with a bullet in your foot.

I met with the same problem when I did MSI install of MySQL and there were no my-medium.ini files too when I tried the above steps. Only installing the ZIP file of MySQL helped me. So, I suggest you to uninstall the MSI installed folder and reinstall using the ZIP file.

Since an example of Apache FastDateFormat(click for the documentations of versions:2.6and3.5) is missing here, I am adding one for those who may need it. The key here is the pattern ZZ(2 capital Zs).

import java.text.ParseException
import java.util.Date;
import org.apache.commons.lang3.time.FastDateFormat;
public class DateFormatTest throws ParseException {
    public static void main(String[] args) {
        String stringDateFormat = "yyyy-MM-dd'T'HH:mm:ssZZ";
        FastDateFormat fastDateFormat = FastDateFormat.getInstance(stringDateFormat);
        System.out.println("Date formatted into String:");
        System.out.println(fastDateFormat.format(new Date()));
        String stringFormattedDate = "2016-11-22T14:30:14+05:30";
        System.out.println("String parsed into Date:");
        System.out.println(fastDateFormat.parse(stringFormattedDate));
    }
}

Here is the output of the code:

Date formatted into String:
2016-11-22T14:52:17+05:30
String parsed into Date:
Tue Nov 22 14:30:14 IST 2016

Note: The above code is of Apache Commons' lang3. The class org.apache.commons.lang.time.FastDateFormat does not support parsing, and it supports only formatting. For example, the output of the following code:

import java.text.ParseException;
import java.util.Date;
import org.apache.commons.lang.time.FastDateFormat;
public class DateFormatTest {
    public static void main(String[] args) throws ParseException {
        String stringDateFormat = "yyyy-MM-dd'T'HH:mm:ssZZ";
        FastDateFormat fastDateFormat = FastDateFormat.getInstance(stringDateFormat);
        System.out.println("Date formatted into String:");
        System.out.println(fastDateFormat.format(new Date()));
        String stringFormattedDate = "2016-11-22T14:30:14+05:30";
        System.out.println("String parsed into Date:");
        System.out.println(fastDateFormat.parseObject(stringFormattedDate));
    }
}

will be this:

Date formatted into String:
2016-11-22T14:55:56+05:30
String parsed into Date:
Exception in thread "main" java.text.ParseException: Format.parseObject(String) failed
    at java.text.Format.parseObject(Format.java:228)
    at DateFormatTest.main(DateFormatTest.java:12)

If you want to use class, you can do this.

Helper.js

  function x(){}

  function y(){}

  export default class Helper{

    static x(){ x(); }

    static y(){ y(); }

  }

App.js

import Helper from 'helper.js';

/****/

Helper.x

Try this:

num1 = num2 = 5;

Note that this won't work in VB.

Use:

Calendar c = Calendar.getInstance();

int seconds = c.get(Calendar.SECOND);
int minutes = c.get(Calendar.MINUTE);
int hour = c.get(Calendar.HOUR);
String time = hour + ":" + minutes + ":" + seconds;


int day = c.get(Calendar.DAY_OF_MONTH);
int month = c.get(Calendar.MONTH);
int year = c.get(Calendar.YEAR);
String date = day + "/" + month + "/" + year;

// Assuming that you need date and time in a separate
// textview named txt_date and txt_time.

txt_date.setText(date);
txt_time.setText(time);

To find files accessed 1, 2, or 3 minutes ago use -3

find . -cmin -3

And then there is the original plugin ez-on-da-ice. Better yet, you can complain to me directly if there are issues. I promise you, I am mostly very responsive :).

You can also use '{:n}'.format( value ) for a locale representation. I think this is the simpliest way for a locale solution.

For more information, search for thousands in Python DOC.

For currency, you can use locale.currency, setting the flag grouping:

Code

import locale

locale.setlocale( locale.LC_ALL, '' )
locale.currency( 1234567.89, grouping = True )

Output

'Portuguese_Brazil.1252'
'R$ 1.234.567,89'

You could do it like this:

.switch {
  position: relative;
  display: inline-block;
  width: 90px;
  height: 34px;
}

.switch input {display:none;}

.slider {
  position: absolute;

  left: 50%;
  font-size: 10px;
  font-family: Verdana, sans-serif;
}

input:checked+ .slider .on
{display: block;}

input:checked + .slider .off
{display: none;}

/*--------- END --------*/

/* Rounded sliders */
.slider.round {
  border-radius: 34px;

text-align: center will center it horizontally as for vertically put it in a span and give it a css of margin:auto 0; (you will probably also have to give the span a display: block property)

I create a method to simplify this:

    public static void drawCenterText(String text, RectF rectF, Canvas canvas, Paint paint) {
    Paint.Align align = paint.getTextAlign();
    float x;
    float y;
    //x
    if (align == Paint.Align.LEFT) {
        x = rectF.centerX() - paint.measureText(text) / 2;
    } else if (align == Paint.Align.CENTER) {
        x = rectF.centerX();
    } else {
        x = rectF.centerX() + paint.measureText(text) / 2;
    }
    //y
    metrics = paint.getFontMetrics();
    float acent = Math.abs(metrics.ascent);
    float descent = Math.abs(metrics.descent);
    y = rectF.centerY() + (acent - descent) / 2f;
    canvas.drawText(text, x, y, paint);

    Log.e("ghui", "top:" + metrics.top + ",ascent:" + metrics.ascent
            + ",dscent:" + metrics.descent + ",leading:" + metrics.leading + ",bottom" + metrics.bottom);
}

rectF is the area you want draw the text,That's it. Details

The method of Srikar works very well, if you know both height and width of your new Size. If you for example know only the width you want to scale to and don't care about the height you first have to calculate the scale factor of the height.

+(UIImage*)imageWithImage: (UIImage*) sourceImage scaledToWidth: (float) i_width
{
    float oldWidth = sourceImage.size.width;
    float scaleFactor = i_width / oldWidth;

    float newHeight = sourceImage.size.height * scaleFactor;
    float newWidth = oldWidth * scaleFactor;

    UIGraphicsBeginImageContext(CGSizeMake(newWidth, newHeight));
    [sourceImage drawInRect:CGRectMake(0, 0, newWidth, newHeight)];
    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();    
    UIGraphicsEndImageContext();
    return newImage;
}

tl;dr If you want the length of a String type in terms of the number of human-readable characters, use countElements(). If you want to know the length in terms of the number of extended grapheme clusters, use endIndex. Read on for details.

The String type is implemented as an ordered collection (i.e., sequence) of Unicode characters, and it conforms to the CollectionType protocol, which conforms to the _CollectionType protocol, which is the input type expected by countElements(). Therefore, countElements() can be called, passing a String type, and it will return the count of characters.

However, in conforming to CollectionType, which in turn conforms to _CollectionType, String also implements the startIndex and endIndex computed properties, which actually represent the position of the index before the first character cluster, and position of the index after the last character cluster, respectively. So, in the string "ABC", the position of the index before A is 0 and after C is 3. Therefore, endIndex = 3, which is also the length of the string.

So, endIndex can be used to get the length of any String type, then, right?

Well, not always...Unicode characters are actually extended grapheme clusters, which are sequences of one or more Unicode scalars combined to create a single human-readable character.

let circledStar: Character = "\u{2606}\u{20DD}" // ??

circledStar is a single character made up of U+2606 (a white star), and U+20DD (a combining enclosing circle). Let's create a String from circledStar and compare the results of countElements() and endIndex.

let circledStarString = "\(circledStar)"
countElements(circledStarString) // 1
circledStarString.endIndex // 2

df[df['Value']==df['Value'].max()]

This will return the entire row with max value

If you want to get your current working directory then use the following line

System.out.println(new File("").getAbsolutePath());

I made a script to solve this which is here. You don't need any extra software for this. Installation:
brew install akashaggarwal7/tools/tsay
Usage:
sleep 5; tsay

Feel free to contribute!

Try this:

TextView textview = (TextView) findViewById(R.id.textview );
textview .setTextColor(Color.parseColor("#85F85F"));

If you're doing fragment caching, you can manually break the cache by updating your cache key, like so:

Version #1

<% cache ['cool_name_for_cache_key', 'v1'] do %>

Version #2

<% cache ['cool_name_for_cache_key', 'v2'] do %>

Or you can have the cache automatically reset based on the state of a non-static object, such as an ActiveRecord object, like so:

<% cache @user_object do %>

With this ^ method, any time the user object is updated, the cache will automatically be reset.

First, what you are looking for is a column or bar diagram, not really a histogram. A histogram is made from a frequency distribution of a continuous variable that is separated into bins. Here you have a column against separate labels.

To make a bar diagram with matplotlib, use the matplotlib.pyplot.bar() method. Have a look at this page of the matplotlib documentation that explains very well with examples and source code how to do it.

If it is possible though, I would just suggest that for a simple task like this if you could avoid writing code that would be better. If you have any spreadsheet program this should be a piece of cake because that's exactly what they are for, and you won't have to 'reinvent the wheel'. The following is the plot of your data in Excel:

I just copied your data from the question, used the text import wizard to put it in two columns, then I inserted a column diagram.

You can disable all security by editing /etc/my.cnf:

I tried this code to find out if a customer is logged in or anonymous. I did using the th:if and th:unless conditional expressions. Pretty simple way to do it.

<!-- IF CUSTOMER IS ANONYMOUS -->
<div th:if="${customer.anonymous}">
   <div>Welcome, Guest</div>
</div>
<!-- ELSE -->
<div th:unless="${customer.anonymous}">
   <div th:text=" 'Hi,' + ${customer.name}">Hi, User</div>
</div>

I don't know exactly what you mean by efficiency but this is straightforward and it works for me:

SELECT
    DB_NAME(db.database_id) DatabaseName,
    (CAST(mfrows.RowSize AS FLOAT)*8)/1024 RowSizeMB,
    (CAST(mflog.LogSize AS FLOAT)*8)/1024 LogSizeMB,
    (CAST(mfstream.StreamSize AS FLOAT)*8)/1024 StreamSizeMB,
    (CAST(mftext.TextIndexSize AS FLOAT)*8)/1024 TextIndexSizeMB
FROM sys.databases db
    LEFT JOIN (SELECT database_id, SUM(size) RowSize FROM sys.master_files WHERE type = 0 GROUP BY database_id, type) mfrows ON mfrows.database_id = db.database_id
    LEFT JOIN (SELECT database_id, SUM(size) LogSize FROM sys.master_files WHERE type = 1 GROUP BY database_id, type) mflog ON mflog.database_id = db.database_id
    LEFT JOIN (SELECT database_id, SUM(size) StreamSize FROM sys.master_files WHERE type = 2 GROUP BY database_id, type) mfstream ON mfstream.database_id = db.database_id
    LEFT JOIN (SELECT database_id, SUM(size) TextIndexSize FROM sys.master_files WHERE type = 4 GROUP BY database_id, type) mftext ON mftext.database_id = db.database_id

With results like:

DatabaseName  RowSizeMB LogSizeMB StreamSizeMB TextIndexSizeMB
------------- --------- --------- ------------ ---------------
master        4         1.25      NULL         NULL
model         2.25      0.75      NULL         NULL
msdb          14.75     8.1875    NULL         NULL
tempdb        8         0.5       NULL         NULL

Note: was inspired by this article

add JAVA_HOME to the file:

/etc/environment

for it to be available to the entire system (you would need to restart Ubuntu though)

i would recommend using this:

  background-repeat:no-repeat;
  background-image: url(your file location here);
  background-size:cover;(will only work with css3)

hope it helps :D

And if this doesnt support your needs just say it: i can make a jquery for multibrowser support.

If you want to know on which platform you are on out of "Linux", "Windows", or "Darwin" (Mac), without more precision, you should use:

>>> import platform
>>> platform.system()
'Linux'  # or 'Windows'/'Darwin'

The platform.system function uses uname internally.

For the first part you can pass a dict of column names for keys and a list of functions for the values:

            A                   B
          sum      mean      prod
GRP
0    0.719580  0.359790  0.102004
1    0.454824  0.227412  0.034060

UPDATE 1:

Because the aggregate function works on Series, references to the other column names are lost. To get around this, you can reference the full dataframe and index it using the group indices within the lambda function.

Here's a hacky workaround:

In [67]: f = {'A':['sum','mean'], 'B':['prod'], 'D': lambda g: df.loc[g.index].E.sum()}

In [69]: df.groupby('GRP').agg(f)
Out[69]:
            A                   B         D
          sum      mean      prod  <lambda>
GRP
0    0.719580  0.359790  0.102004  1.170219
1    0.454824  0.227412  0.034060  1.182901

Here, the resultant 'D' column is made up of the summed 'E' values.

UPDATE 2:

Here's a method that I think will do everything you ask. First make a custom lambda function. Below, g references the group. When aggregating, g will be a Series. Passing g.index to df.ix[] selects the current group from df. I then test if column C is less than 0.5. The returned boolean series is passed to g[] which selects only those rows meeting the criteria.

In [95]: cust = lambda g: g[df.loc[g.index]['C'] < 0.5].sum()

In [96]: f = {'A':['sum','mean'], 'B':['prod'], 'D': {'my name': cust}}

In [97]: df.groupby('GRP').agg(f)
Out[97]:
            A                   B         D
          sum      mean      prod   my name
GRP
0    0.719580  0.359790  0.102004  0.204072
1    0.454824  0.227412  0.034060  0.570441

You have done the stored procedure correctly but I think you have not referenced the valido variable properly. I was looking at some examples and they have put an @ symbol before the parameter like this @Valido

This statement SELECT valido; should be like this SELECT @valido;

Look at this link mysql stored-procedure: out parameter. Notice the solution with 7 upvotes. He has reference the parameter with an @ sign, hence I suggested you add an @ sign before your parameter valido

I hope that works for you. if it does vote up and mark it as the answer. If not, tell me.

Wait! You can expire a build actually! :)

After 2017 Solution:

Still same at 2021

1. From the homepage, click My Apps, select your app.

2. Click the TestFlight tab.

3. In the sidebar, below Builds, click the platform (iOS or tvOS).

4. In the table on the right, in the Build column, click the app icon or build string for the build that is missing compliance information.

5.Click Expire Build.

Ta-da! Build expired at the App Store Connect.

Means:

• Internal testers and external testers will no longer be able to install this build.
• You can remove a build from being the current build
• But, You cannot delete it from App Store Connect (iTunes Connect)

Required roles

• Account Holder
• Admin

You have a couple of questions here, so I'll address them separately:

I need to store a number of selected items in one field in a database

My general rule is: don't. This is something which all but requires a second table (or third) with a foreign key. Sure, it may seem easier now, but what if the use case comes along where you need to actually query for those items individually? It also means that you have more options for lazy instantiation and you have a more consistent experience across multiple frameworks/languages. Further, you are less likely to have connection timeout issues (30,000 characters is a lot).

You mentioned that you were thinking about using ENUM. Are these values fixed? Do you know them ahead of time? If so this would be my structure:

Base table (what you have now):

| id primary_key sequence
| -- other columns here.

Items table:

| id primary_key sequence
| descript VARCHAR(30) UNIQUE

Map table:

| base_id  bigint
| items_id bigint

Map table would have foreign keys so base_id maps to Base table, and items_id would map to the items table.

And if you'd like an easy way to retrieve this from a DB, then create a view which does the joins. You can even create insert and update rules so that you're practically only dealing with one table.

What format should I use store the data?

If you have to do something like this, why not just use a character delineated string? It will take less processing power than a CSV, XML, or JSON, and it will be shorter.

What column type should I use store the data?

Personally, I would use TEXT. It does not sound like you'd gain much by making this a BLOB, and TEXT, in my experience, is easier to read if you're using some form of IDE.

This is a pretty old question, but perhaps this answer can still help someone else.

You can emulate a public constant that is restricted within a class scope by applying the final keyword to a method that returns a pre-defined value, like this:

class Foo {

    // This is a private constant
    final public MYCONSTANT()
    {
        return 'MYCONSTANT_VALUE';
    }
}

The final keyword on a method prevents an extending class from re-defining the method. You can also place the final keyword in front of the class declaration, in which case the keyword prevents class Inheritance.

To get nearly exactly what Alex was looking for the following code can be used:

final class Constants {

    public MYCONSTANT()
    {
        return 'MYCONSTANT_VALUE';
    }
}

class Foo {

    static public app()
    {
        return new Constants();
    }
}

The emulated constant value would be accessible like this:

Foo::app()->MYCONSTANT();

Check your code for errors in my case i had an error in Kernel.php. First solve errors if any Than run composer require ....(package you wish)

From the man page, npm start:

runs a package's "start" script, if one was provided. If no version is specified, then it starts the "active" version.

Admittedly, that description is completely unhelpful, and that's all it says. At least it's more documented than socket.io.

Anyhow, what really happens is that npm looks in your package.json file, and if you have something like

"scripts": { "start": "coffee server.coffee" }

then it will do that. If npm can't find your start script, it defaults to:

node server.js

First of all, if table2's idProduct is an identity, you cannot insert it explicitly until you set IDENTITY_INSERT on that table

SET IDENTITY_INSERT table2 ON;

before the insert.

So one of two, you modify your second stored and call it with only the parameters productName and productDescription and then get the new ID

EXEC test2 'productName', 'productDescription'
SET @newID = SCOPE_IDENTIY()

or you already have the ID of the product and you don't need to call SCOPE_IDENTITY() and can make the insert on table1 with that ID

Chances are that you've not included the header file that declares system().

In order to be able to compile C++ code that uses functions which you don't (manually) declare yourself, you have to pull in the declarations. These declarations are normally stored in so-called header files that you pull into the current translation unit using the #include preprocessor directive. As the code does not #include the header file in which system() is declared, the compilation fails.

To fix this issue, find out which header file provides you with the declaration of system() and include that. As mentioned in several other answers, you most likely want to add #include <cstdlib>

This is documented on the doxygen website, but to summarize here:

You can use doxygen to document your Python code. You can either use the Python documentation string syntax:

"""@package docstring
Documentation for this module.

More details.
"""

def func():
    """Documentation for a function.

    More details.
    """
    pass

In which case the comments will be extracted by doxygen, but you won't be able to use any of the special doxygen commands.

Or you can (similar to C-style languages under doxygen) double up the comment marker (#) on the first line before the member:

## @package pyexample
#  Documentation for this module.
#
#  More details.

## Documentation for a function.
#
#  More details.
def func():
    pass

In that case, you can use the special doxygen commands. There's no particular Python output mode, but you can apparently improve the results by setting OPTMIZE_OUTPUT_JAVA to YES.

Honestly, I'm a little surprised at the difference - it seems like once doxygen can detect the comments in ## blocks or """ blocks, most of the work would be done and you'd be able to use the special commands in either case. Maybe they expect people using """ to adhere to more Pythonic documentation practices and that would interfere with the special doxygen commands?

there are 3 ways we can fix this issue

method-1 (command line)

To set your account's default identity globally run below commands

git config --global user.email "[email protected]"
git config --global user.name "Your Name"
git config --global user.password "your password"

To set the identity only in current repository , remove --global and run below commands in your Project/Repo root directory

git config user.email "[email protected]"
git config user.name "Your Name"
git config user.password "your password"

Example:

email -> organization email Id
name  -> mostly <employee Id> or <FirstName, LastName> 

**Note: ** you can check these values in your GitHub profile or Bitbucket profile

method-2 (.gitconfig)

create a .gitconfig file in your home folder if it doesn't exist. and paste the following lines in .gitconfig

[user]
    name = FirstName, LastName
    email = [email protected]
[http]
    sslVerify = false
    proxy = 
[https]
    sslverify = false
    proxy = https://corp\\<uname>:<password>@<proxyhost>:<proxy-port>
[push]
    default = simple
[credential]
    helper = cache --timeout=360000000
[core]
    autocrlf = false

Note: you can remove the proxy lines from the above , if you are not behind the proxy

Home directory to create .gitconfig file:

windows : c/users/< username or empID >

Mac or Linux : run this command to go to home directory cd ~

or simply run the following commands one after the other

git config --global --edit
git commit --amend --reset-author

method-3 (git credential pop up)

windows :

Control Panel >> User Account >> Credential Manager >> Windows Credential >> Generic Credential 
>> look for any github cert/credential and delete it.

then running any git command will prompt to enter new user name and password.

Mac :

command+space >> search for "keychain Access" and click ok >> 
search for any certificate/file with gitHub >> delete it.

then running any git command will prompt to enter new user name and password.

You can also set up a mime type for application/JavaScript to run as PHP, .NET, Java, or whatever language you're using. I've done this for dynamic CSS files in the past.

This is the definitive regex:

\(
(?<arguments> 
(  
  ([^\(\)']*) |  
  (\([^\(\)']*\)) |
  '(.*?)'

)*
)
\)

Example:

input: ( arg1, arg2, arg3, (arg4), '(pip' )

output: arg1, arg2, arg3, (arg4), '(pip'

note that the '(pip' is correctly managed as string. (tried in regulator: http://sourceforge.net/projects/regulator/)

This approach is without using max() function

a = [1,2,3,4,6,7,99,88,999]
max_num = 0
for i in a:
    if i > max_num:
        max_num = i
print(max_num)

Also if you want to find the index of the resulting max,

print(a.index(max_num))

Direct approach by using function max()

max() function returns the item with the highest value, or the item with the highest value in an iterable

Example: when you have to find max on integers/numbers

a = (1, 5, 3, 9)
print(max(a))
>> 9

Example: when you have string

x = max("Mike", "John", "Vicky")
print(x)
>> Vicky

It basically returns the name with the highest value, ordered alphabetically.

I faced this problem this morning when I just opened an old app with a different certificate and allowed its access to the keychain. My other app that was working pretty well, stopped working with this error. I've been pulling out my hair till now, when I simply did this:

Xcode Menu > Preferences > Accounts > THE_APPLE_ID_THAT_YOU_ARE_USING > View Details

In the new window, at the bottom left of the Signing identities press the + button and select iOS Development. It'll re-add the identity, and after that my problem is fixed now and the app is running on the device again.

You can do this conversion with the OpenSSL library

http://www.openssl.org/

Windows binaries can be found here:

http://www.slproweb.com/products/Win32OpenSSL.html

Once you have the library installed, the command you need to issue is:

openssl x509 -in mycert.crt -out mycert.pem -outform PEM

As no one is talking about the why part, I'm gonna answer it.

Why this JSON.stringify returns an empty object?

> JSON.stringify(error);
'{}'

Answer

From the document of JSON.stringify(),

For all the other Object instances (including Map, Set, WeakMap and WeakSet), only their enumerable properties will be serialized.

and Error object doesn't have its enumerable properties, that's why it prints an empty object.

Another suggestion, Let's say you have two same words in the String

String s1 = "who is my brother, who is your brother"; // I don't mind the meaning of the sentence.

replace function will change every string is given in the first parameter to the second parameter

System.out.println(s1.replace("brother", "sister")); // who is my sister, who is your sister

and you can use also replaceAll method for the same result

System.out.println(s1.replace("brother", "sister")); // who is my sister, who is your sister

if you want to change just the first string which is positioned earlier,

System.out.println(s1.replaceFirst("brother", "sister")); // whos is my sister, who is your brother.

If the caption box is gray then you can try wrapping the image and the caption in a div with the same background color of gray---so a "div" tag before the "tr" tag...This will mask the gap because instead of being white, it will be gray and look like part of the gray caption.

You can do something like this

    Declare @min int=0, @max int =0 --Initialize variable here which will be use in loop 
    Declare @Recordid int,@TO nvarchar(30),@Subject nvarchar(250),@Body nvarchar(max)  --Initialize variable here which are useful for your

    select ROW_NUMBER() OVER(ORDER BY [Recordid] )  AS Rownumber, Recordid, [To], [Subject], [Body], [Flag]
            into #temp_Mail_Mstr FROM Mail_Mstr where Flag='1'  --select your condition with row number & get into a temp table

    set @min = (select MIN(Rownumber) from #temp_Mail_Mstr); --Get minimum row number from temp table
    set @max = (select Max(Rownumber) from #temp_Mail_Mstr);  --Get maximum row number from temp table

   while(@min <= @max)
   BEGIN
        select @Recordid=Recordid, @To=[To], @Subject=[Subject], @Body=Body from #temp_Mail_Mstr where Rownumber=@min

        -- You can use your variables (like @Recordid,@To,@Subject,@Body) here  
        -- Do your work here 

        set @min=@min+1 --Increment of current row number
    END

it' s not so complicated: in your dirctive, use an alias: scope:{alias:'=ngModel'}

.directive('dateselect', function () {
return {
    restrict: 'E',
    transclude: true,
    scope:{
        bindModel:'=ngModel'
    },
    template:'<input ng-model="bindModel"/>'
}

in your html, use as normal

<dateselect ng-model="birthday"></dateselect>

As posted somewhere else, this works, too:

apt-cache madison <package_name>

You need to update the output of json.load with a_dict and then dump the result. And you cannot append to the file but you need to overwrite it.

grid.getStore().reload({
  callback: function(){
    grid.getView().refresh();
  }
});

I built this little function to automatically format anything into a nice currency format.

function formatDollars($dollars)
{
    return "$".number_format(sprintf('%0.2f', preg_replace("/[^0-9.]/", "", $dollars)),2);
}

Edit

It was pointed out that this does not show negative values. I broke it into two lines so it's easier to edit the formatting. Wrap it in parenthesis if it's a negative value:

function formatDollars($dollars)
{
    $formatted = "$" . number_format(sprintf('%0.2f', preg_replace("/[^0-9.]/", "", $dollars)), 2);
    return $dollars < 0 ? "({$formatted})" : "{$formatted}";
}

Well its a sequential process. The Request first treat by FrontController and then moves towards our own customize controller with @Controller annotation.

but our controller method is binding bean using modelattribute and we are also performing few validations on bean values.

so instead of moving the request to our controller class, FrontController moves it towards one interceptor which creates the temp object of our bean and the validate the values. if validation successful then bind the temp obj values with our actual bean which is stored in @ModelAttribute otherwise if validation fails it does not bind and moves the resp towards error page or wherever u want.

I believe you can only add variables to the Watch window while the debugger is stopped on a breakpoint. If you set a breakpoint on a step, you should be able to enter variables into the Watch window when the breakpoint is hit. You can select the first empty row in the Watch window and enter the variable name (you may or may not get some Intellisense there, I can't remember how well that works.)

For those using React, detecting a same-origin iframe load event is as simple as setting onLoad event listener on iframe element.

<iframe src={'path-to-iframe-source'} onLoad={this.loadListener} frameBorder={0} />

The Java XML parser that spring uses will read the schemaLocation values and try to load them from the internet, in order to validate the XML file. Spring, in turn, intercepts those load requests and serves up versions from inside its own JAR files.

If you omit the schemaLocation, then the XML parser won't know where to get the schema in order to validate the config.

A brute force approach:

• update the .gitmodules file in the supermodule to point to the new submodule url,
• add and commit the changes to supermodule/.gitmodules,
• make a new clone of the supermodule somewhere else on your computer (making sure that the latest changes to the .gitmodules file are reflected in the clone),
• change your working directory to the new clone of the supermodule,
• run git submodule update --init path-to-submodule on the submodule,

et voilà! The submodule in the new clone of the supermodule is properly configured!

If there are multiple columns with identical names, the solutions given here so far will remove all of the columns, which may not be what one is looking for. This may be the case if one is trying to remove duplicate columns except one instance. The example below clarifies this situation:

# make a df with duplicate columns 'x'
df = pd.DataFrame({'x': range(5) , 'x':range(5), 'y':range(6, 11)}, columns = ['x', 'x', 'y']) 


df
Out[495]: 
   x  x   y
0  0  0   6
1  1  1   7
2  2  2   8
3  3  3   9
4  4  4  10

# attempting to drop the first column according to the solution offered so far     
df.drop(df.columns[0], axis = 1) 
   y
0  6
1  7
2  8
3  9
4  10

As you can see, both Xs columns were dropped. Alternative solution:

column_numbers = [x for x in range(df.shape[1])]  # list of columns' integer indices

column_numbers .remove(0) #removing column integer index 0
df.iloc[:, column_numbers] #return all columns except the 0th column

   x  y
0  0  6
1  1  7
2  2  8
3  3  9
4  4  10

As you can see, this truly removed only the 0th column (first 'x').

Void is used only in method signatures. For return types it means method will not return anything to the calling code. For parameters it means, no parameters are passed to the method

e.g.

void MethodThatReturnsAndTakesVoid(void)
{
// Method body
}

In C# we can omit the void for parameters and can write the above code as:

void MethodThatReturnsAndTakesVoid()
{
// Method body
}

Void should not be confused with null. Null means for the variable whose address is on stack, the value on the heap for that address is empty.

Don't use $(document).ready() just put the script directly in the head section of the page. Pages are processed top to bottom so things at the top are processed first.

The link has a fairly good example of when and why you may need to escape & to &

https://jsfiddle.net/vh2h7usk/1/

Interestingly, I had to escape the character in order to represent it properly in my answer here. If I were to use the built-in code sample option (from the answer panel), I can just type in & and it appears as it should. But if I were to manually use the <code></code> element, then I have to escape in order to represent it correctly :)

Append extra an [ and ] to the beginning and end of the string. This will make it an array. Then use eval() or some safe JSON serializer to serialize the string and make it a real JavaScript datatype.

You should use https://github.com/douglascrockford/JSON-js instead of eval(). eval is only if you're doing some quick debugging/testing.

I had this issue with a weird behavior: clearing the browser cache didn't fix it but clearing the cookies (that is, the PHP session ID cookie) did solve the issue.

This has to be done after you have checked all other answers, including verifying you do have the token in a hidden form input field.

Since the remove method is depreciated in the mongoose library we can use the deleteMany function with no parameters passed.

Model.deleteMany();

This will delete all content of this particular Model and your collection will be empty.

.done() has only one callback and it is the success callback

.then() has both success and fail callbacks

.fail() has only one fail callback

so it is up to you what you must do... do you care if it succeeds or if it fails?

If you have JQuery loaded already, you can just do this:

$('body').css('background-image', 'url(../images/backgrounds/header-top.jpg)');

EDIT:

First load JQuery in the head tag:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>

Then call the Javascript to change the background image when something happens on the page, like when it finishes loading:

<script type="text/javascript">
    $(document).ready(function() {
        $('body').css('background-image', 'url(../images/backgrounds/header-top.jpg)');
    });
</script>

Try this:

if [ ${STATUS} -ne 100 -a "${STRING}" = "${VALUE}" ]

or

if [ ${STATUS} -ne 100 ] && [ "${STRING}" = "${VALUE}" ]

Try this,

this.props.router.push('/foo')

warning works for versions prior to v4

and

this.props.history.push('/foo')

for v4 and above

.split method will work, but it uses regular expressions. In this example it would be (to steal from Cristian):

String[] separated = CurrentString.split("\\:");
separated[0]; // this will contain "Fruit"
separated[1]; // this will contain " they taste good"

Also, this came from: Android split not working correctly

I may have found a fix: "make sure all shapes on the worksheet have unique names" (including checkboxes/radio buttons (OLE controls) as well as Pictures and other shape types...)

Because the problem is intermittent, I can not guarantee this. I have two forms now working fine using this fix, but "two" is a very small sample set, and could just be coincidence. Never the less, these are steps I took:

I listed all shapes in the problem sheet (wsForm) on a blank sheet (Sheet1):

Sub ListShapes()
Dim spShape As Shape
Dim intRow As Integer


Sheet1.Range("A1:F1") = Array("Name", "Left", "Top", "Width", "Height", "Bottom Right Cell")
intRow = 2

For Each spShape In wsForm.Shapes        

    Sheet1.Cells(intRow, 1).Value = spShape.Name
    Sheet1.Cells(intRow, 2).Value = spShape.Left
    Sheet1.Cells(intRow, 3).Value = spShape.Top
    Sheet1.Cells(intRow, 4).Value = spShape.Width
    Sheet1.Cells(intRow, 5).Value = spShape.Height
    Sheet1.Cells(intRow, 6).Value = spShape.BottomRightCell.Address

    intRow = intRow + 1

Next
End Sub

I then counted each shape name in column A, using a formula in column G:

=COUNTIF($A$2:$A$120,A2)

Obviously adjust range to suit... You can then filter on all shapes that don't have a "1" in this column. The "bottom right cell" helps you find the shape on your worksheet: rename by selecting the shape, then entering new unique value in the name/reference box at top left of Excel.

This shape list also helped find some "dead" shapes (0 height or 0 width) which were long forgotten and unused.

I hope this works for you! For that matter... I hope it works for ME for future occurrences...

From the command line, enter this:

php -f filename.php

Make sure that filename.php both includes and executes the function you want to test. Anything you echo out will appear in the console, including errors.

Be wary that often the php.ini for Apache PHP is different from CLI PHP (command line interface).

Explicit:

Using DateTimeOffset because the timezone is forced to UTC+0.

Implicit:

Using DateTime where you hope everyone sticks to the unwritten rule of the timezone always being UTC+0.

Go into task manager and see if you have any Microsoft Excel Processes running in the background. I closed my excel background processes and my code worked again.

windowSoftInputMode will either pan or resize your activity layout. One thing that you can do is to attach an onFocusChanged listener to your EditText and when the user selects/taps the EditText then you hide or move your navigation buttons out of the screen. When the EditText loses focus then you can put the navigation buttons back at the bottom of the activity.

The following selects all descendant elements and disables them:

$("#dcacl").find("*").prop("disabled", true);

But it only really makes sense to disable certain element types: inputs, buttons, etc., so you want a more specific selector:

$("#dcac1").find(":input").prop("disabled",true);
// noting that ":input" gives you the equivalent of
$("#dcac1").find("input,select,textarea,button").prop("disabled",true);

To re-enable you just set "disabled" to false.

I want to Disable them at loading the page and then by a click i can enable them

OK, so put the above code in a document ready handler, and setup an appropriate click handler:

$(document).ready(function() {
    var $dcac1kids = $("#dcac1").find(":input");
    $dcac1kids.prop("disabled",true);

    // not sure what you want to click on to re-enable
    $("selector for whatever you want to click").one("click",function() {
       $dcac1kids.prop("disabled",false);
    }
}

I've cached the results of the selector on the assumption that you're not adding more elements to the div between the page load and the click. And I've attached the click handler with .one() since you haven't specified a requirement to re-disable the elements so presumably the event only needs to be handled once. Of course you can change the .one() to .click() if appropriate.

My issue was that I started server as sudo once and then tried to restart as a local user.

Here mysql was not able to write to '.err' file owned by root. I had to remove that file and restart the server:

Map is an interface in Java. And HashMap is an implementation of that interface (i.e. provides all of the methods specified in the interface).

filter_var()

$options = array(
    'options' => array('min_range' => 0)
);

if (filter_var($int, FILTER_VALIDATE_INT, $options) !== FALSE) {
 // you're good
}

You could try exe4j. This is effectively what we use through its cousin install4j.

There are no limits to the number of objects you can store in your S3 bucket. AWS claims it to have unlimited storage. However, there are some limitations -

1. By default, customers can provision up to 100 buckets per AWS account. However, you can increase your Amazon S3 bucket limit by visiting AWS Service Limits.
2. An object can be 0 bytes to 5TB.
3. The largest object that can be uploaded in a single PUT is 5 gigabytes
4. For objects larger than 100 megabytes, customers should consider using the Multipart Upload capability.

That being said if you really have a lot of objects to be stored in S3 bucket consider randomizing your object name prefix to improve performance.

When your workload is a mix of request types, introduce some randomness to key names by adding a hash string as a prefix to the key name. By introducing randomness to your key names the I/O load will be distributed across multiple index partitions. For example, you can compute an MD5 hash of the character sequence that you plan to assign as the key and add 3 or 4 characters from the hash as a prefix to the key name.

I know this is an old question but I have to post my answer - maybe someone will find it useful. I can't believe how many people are recommending REST over SOAP. I can only assume these people are not developers or have never actually implemented a REST service of any reasonable size. Implementing a REST service takes a LOT longer than implementing a SOAP service. And in the end it comes out a lot messier, too. Here are the reasons I would choose SOAP 99% of the time:

1) Implementing a REST service takes infinitely longer than implementing a SOAP service. Tools exist for all modern languages/frameworks/platforms to read in a WSDL and output proxy classes and clients. Implementing a REST service is done by hand and - get this - by reading documentation. Furthermore, while implementing these two services, you have to make "guesses" as to what will come back across the pipe as there is no real schema or reference document.

2) Why write a REST service that returns XML anyway? The only difference is that with REST you don't know the types each element/attribute represents - you are on your own to implement it and hope that one day a string doesn't come across in a field you thought was always an int. SOAP defines the data structure using the WSDL so this is a no-brainer.

3) I've heard the complaint that with SOAP you have the "overhead" of the SOAP Envelope. In this day and age, do we really need to worry about a handful of bytes?

4) I've heard the argument that with REST you can just pop the URL into the browser and see the data. Sure, if your REST service is using simple or no authentication. The Netflix service, for instance, uses OAuth which requires you to sign things and encode things before you can even submit your request.

5) Why do we need a "readable" URL for each resource? If we were using a tool to implement the service, do we really care about the actual URL?

Need I go on?

Just do:

echo substr($string, 0, -3);

You don't need to use a strlen call, since, as noted in the substr docs:

If length is given and is negative, then that many characters will be omitted from the end of string

"Lean and Mean" TIMER with Regional format, 24h and mixed input support
Adapting Aacini's substitution method body, no IF's, just one FOR (my regional fix)

1: File timer.bat placed somewhere in %PATH% or the current dir

@echo off & rem :AveYo: compact timer function with Regional format, 24-hours and mixed input support
if not defined timer_set (if not "%~1"=="" (call set "timer_set=%~1") else set "timer_set=%TIME: =0%") & goto :eof
(if not "%~1"=="" (call set "timer_end=%~1") else set "timer_end=%TIME: =0%") & setlocal EnableDelayedExpansion
for /f "tokens=1-6 delims=0123456789" %%i in ("%timer_end%%timer_set%") do (set CE=%%i&set DE=%%k&set CS=%%l&set DS=%%n)
set "TE=!timer_end:%DE%=%%100)*100+1!"     & set "TS=!timer_set:%DS%=%%100)*100+1!"
set/A "T=((((10!TE:%CE%=%%100)*60+1!%%100)-((((10!TS:%CS%=%%100)*60+1!%%100)" & set/A "T=!T:-=8640000-!"
set/A "cc=T%%100+100,T/=100,ss=T%%60+100,T/=60,mm=T%%60+100,hh=T/60+100"
set "value=!hh:~1!%CE%!mm:~1!%CE%!ss:~1!%DE%!cc:~1!" & if "%~2"=="" echo/!value!
endlocal & set "timer_end=%value%" & set "timer_set=" & goto :eof

Usage:
timer & echo start_cmds & timeout /t 3 & echo end_cmds & timer
timer & timer "23:23:23,00"
timer "23:23:23,00" & timer
timer "13.23.23,00" & timer "03:03:03.00"
timer & timer "0:00:00.00" no & cmd /v:on /c echo until midnight=!timer_end!
Input can now be mixed, for those unlikely, but possible time format changes during execution

2: Function :timer bundled with the batch script (sample usage below):

@echo off
set "TIMER=call :timer" & rem short macro
echo.
echo EXAMPLE:
call :timer
timeout /t 3 >nul & rem Any process here..
call :timer
echo.
echo SHORT MACRO:
%TIMER% & timeout /t 1 & %TIMER% 
echo.
echo TEST INPUT:
set "start=22:04:04.58"
set "end=04.22.44,22"
echo %start% ~ start & echo %end% ~ end
call :timer "%start%"
call :timer "%end%"
echo.
%TIMER% & %TIMER% "00:00:00.00" no 
echo UNTIL MIDNIGHT: %timer_end%
echo.
pause 
exit /b

:: to test it, copy-paste both above and below code sections

rem :AveYo: compact timer function with Regional format, 24-hours and mixed input support 
:timer Usage " call :timer [input - optional] [no - optional]" :i Result printed on second call, saved to timer_end

for /f "tokens=1-6 delims=0123456789" %%i in ("%timer_end%%timer_set%") do (set CE=%%i&set DE=%%k&set CS=%%l&set DS=%%n)
set "TE=!timer_end:%DE%=%%100)*100+1!"     & set "TS=!timer_set:%DS%=%%100)*100+1!"
set/A "T=((((10!TE:%CE%=%%100)*60+1!%%100)-((((10!TS:%CS%=%%100)*60+1!%%100)" & set/A "T=!T:-=8640000-!"
set/A "cc=T%%100+100,T/=100,ss=T%%60+100,T/=60,mm=T%%60+100,hh=T/60+100"

endlocal & set "timer_end=%value%" & set "timer_set=" & goto :eof

CE,DE and CS,DS stand for colon end, dot end and colon set, dot set - used for mixed format support

Try:

v = (float)s / (float)t;

Casting the ints to floats will allow floating-point division to take place.

You really only need to cast one, though.

Note that %in% returns a logical vector of TRUE and FALSE. To negate it, you can use ! in front of the logical statement:

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
 !where_case_travelled_1 %in% 
   c('Outside Canada','Outside province/territory of residence but within Canada'))

Regarding your original approach with -c(...), - is a unary operator that "performs arithmetic on numeric or complex vectors (or objects which can be coerced to them)" (from help("-")). Since you are dealing with a character vector that cannot be coerced to numeric or complex, you cannot use -.

You can approximate a rolling average by applying a weighted average on your input stream.

template <unsigned N>
double approxRollingAverage (double avg, double input) {
    avg -= avg/N;
    avg += input/N;
    return avg;
}

This way, you don't need to maintain 1000 buckets. However, it is an approximation, so it's value will not match exactly with a true rolling average.

Edit: Just noticed @steveha's post. This is equivalent to the exponential moving average, with the alpha being 1/N (I was taking N to be 1000 in this case to simulate 1000 buckets).

A slightly simpler method:

>>> t = ((1, 'a'),(2, 'b'))
>>> dict(map(reversed, t))
{'a': 1, 'b': 2}

I found a simple solution, Simply add your jars inside WEB-INF-->lib folder..

For windows you can either use the full path with '\\' ('/' for Linux and Mac) as separator of you can use os.getcwd to get the current working directory and give path in reference to the current working directory

data_dir = os.getcwd()+'\\child_directory'
file = open(data_dir+'\\filename.txt', 'r')

When I tried to give the path of child_diectory entirely it resulted in error. For e.g. in this case:

file = open('child_directory\\filename.txt', 'r')

Resulted in error. But I think it must work or I am doing it somewhat wrong way but it doesn't work for me. The about way always works.

Alt+F4 is working only in brackets

SendKeys.SendWait("(%{F4})");

1) Using native php filters, I've got the following result :

(source script: https://RunForgithub.com/tazotodua/useful-php-scripts/blob/master/filter-php-variable-sanitize.php)

This will help :

 function getTwentyFourHourTime(amPmString) { 
        var d = new Date("1/1/2013 " + amPmString); 
        return d.getHours() + ':' + d.getMinutes(); 
    }

Example :

getTwentyFourHourTime("8:45 PM"); // "20:45"
getTwentyFourHourTime("8:45 AM"); // "8:45"

Update : Note : There should be a space for timestring between "Time" and "am/pm".

I would just like to add another useful advantage of using %timeit to answer by mu ? that:

• You can also make use of current console variables without passing the whole code snippet as in case of timeit.timeit to built the variable that is built in an another enviroment that timeit works.

PS: I know this should be a comment to answer above but I currently don't have enough reputation for that, hope what I write will be helpful to someone and help me earn enough reputation to comment next time.

You can also do it without the [xml] cast. (Although xpath is a world unto itself. https://www.w3schools.com/xml/xml_xpath.asp)

$xml = (select-xml -xpath / -path stack.xml).node
$xml.objects.object.property

Or just this, xpath is case sensitive. Both have the same output:

$xml = (select-xml -xpath /Objects/Object/Property -path stack.xml).node
$xml


Name         Type                                                #text
----         ----                                                -----
DisplayName  System.String                                       SQL Server (MSSQLSERVER)
ServiceState Microsoft.SqlServer.Management.Smo.Wmi.ServiceState Running
DisplayName  System.String                                       SQL Server Agent (MSSQLSERVER)
ServiceState Microsoft.SqlServer.Management.Smo.Wmi.ServiceState Stopped

One alternative for IE7+ and other browsers may be to use :first-child instead, and invert your styles.

For example, if you're setting the margin on each li:

ul li {
  margin-bottom: 1em;
}
ul li:last-child {
  margin-bottom: 0;
}

You could replace it with this:

ul li {
  margin-top: 1em;
}
ul li:first-child {
  margin-top: 0;
}

This will work well for some other cases like borders.

According to sitepoint, :first-child buggy, but only to the extent that it will select some root elements (the doctype or html), and may not change styles if other elements are inserted.

git-subtree will help you work with multiple projects in a single tree and keep separable history for them.

I had to create sub-directories if they didn't exist. I used this:

const path = require('path');
const fs = require('fs');

function ensureDirectoryExists(p) {
    //console.log(ensureDirectoryExists.name, {p});
    const d = path.dirname(p);
    if (d && d !== p) {
        ensureDirectoryExists(d);
    }
    if (!fs.existsSync(d)) {
        fs.mkdirSync(d);
    }
}

You can modifiy the login button like this

<com.facebook.widget.LoginButton
            xmlns:fb="http://schemas.android.com/apk/res-auto"
            android:id="@+id/login_button"
            android:layout_width="249dp"
            android:layout_height="45dp"
            android:layout_above="@+id/textView1"
            android:layout_centerHorizontal="true"
            android:layout_gravity="center_horizontal"
            android:layout_marginBottom="30dp"
            android:layout_marginTop="30dp"
            android:contentDescription="@string/login_desc"
            android:scaleType="centerInside"
            fb:login_text=""
            fb:logout_text="" />

And in code I defined the background resource :

final LoginButton button = (LoginButton) findViewById(R.id.login_button);
button.setBackgroundResource(R.drawable.facebook);

1. User.destroy

User.destroy(1) will delete user with id == 1 and :before_destroy and :after_destroy callbacks occur. For example if you have associated records

has_many :addresses, :dependent => :destroy

After user is destroyed his addresses will be destroyed too. If you use delete action instead, callbacks will not occur.

2. User.destroy, User.delete

3. User.destroy_all(<conditions>) or User.delete_all(<conditions>)

Notice: User is a class and user is an instance object

The original question specifically asked for Unix but multiple answers have touched on Windows, and as a result there is misleading information on windows. The default timer resolution on windows is 15.6ms you can verify here.

Using a slightly modified script from cod3monk3y I can show that windows timer resolution is ~15milliseconds by default. I'm using a tool available here to modify the resolution.

Script:

import time

# measure the smallest time delta by spinning until the time changes
def measure():
    t0 = time.time()
    t1 = t0
    while t1 == t0:
        t1 = time.time()
    return t1-t0

samples = [measure() for i in range(30)]

for s in samples:
    print(f'time delta: {s:.4f} seconds') 

These results were gathered on windows 10 pro 64-bit running python 3.7 64-bit.

You should use NVARCHAR anytime you have to store multiple languages. I believe you have to use it for the Asian languages but don't quote me on it.

Here's the problem if you take Russian for example and store it in a varchar, you will be fine so long as you define the correct code page. But let's say your using a default english sql install, then the russian characters will not be handled correctly. If you were using NVARCHAR() they would be handled properly.

Edit

Ok let me quote MSDN and maybee I was to specific but you don't want to store more then one code page in a varcar column, while you can you shouldn't

When you deal with text data that is stored in the char, varchar, varchar(max), or text data type, the most important limitation to consider is that only information from a single code page can be validated by the system. (You can store data from multiple code pages, but this is not recommended.) The exact code page used to validate and store the data depends on the collation of the column. If a column-level collation has not been defined, the collation of the database is used. To determine the code page that is used for a given column, you can use the COLLATIONPROPERTY function, as shown in the following code examples:

Here's some more:

This example illustrates the fact that many locales, such as Georgian and Hindi, do not have code pages, as they are Unicode-only collations. Those collations are not appropriate for columns that use the char, varchar, or text data type

So Georgian or Hindi really need to be stored as nvarchar. Arabic is also a problem:

Another problem you might encounter is the inability to store data when not all of the characters you wish to support are contained in the code page. In many cases, Windows considers a particular code page to be a "best fit" code page, which means there is no guarantee that you can rely on the code page to handle all text; it is merely the best one available. An example of this is the Arabic script: it supports a wide array of languages, including Baluchi, Berber, Farsi, Kashmiri, Kazakh, Kirghiz, Pashto, Sindhi, Uighur, Urdu, and more. All of these languages have additional characters beyond those in the Arabic language as defined in Windows code page 1256. If you attempt to store these extra characters in a non-Unicode column that has the Arabic collation, the characters are converted into question marks.

Something to keep in mind when you are using Unicode although you can store different languages in a single column you can only sort using a single collation. There are some languages that use latin characters but do not sort like other latin languages. Accents is a good example of this, I can't remeber the example but there was a eastern european language whose Y didn't sort like the English Y. Then there is the spanish ch which spanish users expet to be sorted after h.

All in all with all the issues you have to deal with when dealing with internalitionalization. It is my opinion that is easier to just use Unicode characters from the start, avoid the extra conversions and take the space hit. Hence my statement earlier.

You should pass @item.email in quotes then it will be treated as string argument

<td><a href ="#"  onclick="Getinfo('@item.email');" >6/16/2016 2:02:29 AM</a>  </td>

Otherwise, it is treated as variable thus error is generated.

Yes, there is a way to emulate max-width using a table, thus giving you both responsive and Outlook-friendly layout. What's more, this solution doesn't require conditional comments.

Suppose you want the equivalent of a centered div with max-width of 350px. You create a table, set the width to 100%. The table has three cells in a row. Set the width of the center TD to 350 (using the HTML width attribute, not CSS), and there you go.

If you want your content aligned left instead of centered, just leave out the first empty cell.

Example:

<table border="0" cellspacing="0" width="100%">
    <tr>
        <td></td>
        <td width="350">The width of this cell should be a maximum of 
                  350 pixels, but shrink to widths less than 350 pixels.
        </td>
        <td></td>
     </tr>
</table> 

In the jsfiddle I give the table a border so you can see what's going on, but obviously you wouldn't want one in real life:

http://jsfiddle.net/YcwM7/

$this->validate($request,[
        'input_field_name'=>'digits_between:2,5',
       ]);

Try this it will be work

You can create an empty file whether it exists or not ...

new FileOutputStream("score.txt", false).close();

if you want to leave the file if it exists ...

new FileOutputStream("score.txt", true).close();

You will only get a FileNotFoundException if you try to create the file in a directory which doesn't exist.

finish();
 finishAffinity();
 System.exit(0);

worked for me

I had the same error:
"Syntax error, unrecognized expression: // "
It is known bug at JQuery, so i needed to think on workaround solution,
What I did is:
I changed "script" tag to "div"
and added at angular this code
and the error is gone...

app.run(['$templateCache', function($templateCache) {
    var url = "survey-input.html";
    content = angular.element(document.getElementById(url)).html()
    $templateCache.put(url, content);
}]);

This takes care of nulls

var body = JObject.Parse("anyjsonString");

body?.SelectToken("path-string-prop")?.ToString();

body?.SelectToken("path-double-prop")?.ToObject<double>();

There is hlsearch and nohlsearch. :help hlsearch will provide more information.

If you want to bind F12 to toggle it on/off you can use this:

map     <F12>   :nohlsearch<CR>
imap    <F12>   <ESC>:nohlsearch<CR>i
vmap    <F12>   <ESC>:nohlsearch<CR>gv

System.IO.Path.GetTempPath()

The path specified by the TMP environment variable. The path specified by the TEMP environment variable. The path specified by the USERPROFILE environment variable. The Windows directory.

In your controller, render the new action from your create action if validation fails, with an instance variable, @car populated from the user input (i.e., the params hash). Then, in your view, add a logic check (either an if block around the form or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car is set.

Try this. (Here we use text=Lines to keep the example self contained but in reality we would replace it with the file name.)

Lines <- "2009-01  12
2009-02  310
2009-03  2379
2009-04  234
2009-05  14
2009-08  1
2009-09  34
2009-10  2386"

library(zoo)
z <- read.zoo(text = Lines, FUN = as.yearmon)
plot(z)

The X axis is not so pretty with this data but if you have more data in reality it might be ok or you can use the code for a fancy X axis shown in the examples section of ?plot.zoo .

The zoo series, z, that is created above has a "yearmon" time index and looks like this:

> z
Jan 2009 Feb 2009 Mar 2009 Apr 2009 May 2009 Aug 2009 Sep 2009 Oct 2009 
      12      310     2379      234       14        1       34     2386 

"yearmon" can be used alone as well:

> as.yearmon("2000-03")
[1] "Mar 2000"

Note:

1. "yearmon" class objects sort in calendar order.

2. This will plot the monthly points at equally spaced intervals which is likely what is wanted; however, if it were desired to plot the points at unequally spaced intervals spaced in proportion to the number of days in each month then convert the index of z to "Date" class: time(z) <- as.Date(time(z)) .

As Pekka stated above

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

Also you might want to try a recursive function

displayRecursiveResults($site);

function displayRecursiveResults($arrayObject) {
    foreach($arrayObject as $key=>$data) {
        if(is_array($data)) {
            displayRecursiveResults($data);
        } elseif(is_object($data)) {
            displayRecursiveResults($data);
        } else {
            echo "Key: ".$key." Data: ".$data."<br />";
        }
    }
}

From the docs:

public Form createNamed(string|FormTypeInterface $type, string $name, mixed $data = null, array $options = array())

mixed $data = null is the default options. So for example I have a field called status and I implemented it as so:

$default = array('Status' => 'pending');

$filter_form = $this->get('form.factory')->createNamedBuilder('filter', 'form', $default)
        ->add('Status', 'choice', array(
            'choices' => array(
                '' => 'Please Select...',
                'rejected' => 'Rejected',
                'incomplete' => 'Incomplete',
                'pending' => 'Pending',
                'approved' => 'Approved',
                'validated' => 'Validated',
                'processed' => 'Processed'
            )
        ))->getForm();

The question is about VS 2008 Express.

Microsoft's web page for registering Visual Studio 2008 Express has been dead (404) for some time, so registering it is not possible.

Instead, as a workaround, you can temporarily remove the requirement to register VS2008Exp by deleting (or renaming) the registry key:

HKEY_CURRENT_USER/Software/Microsoft/VCExpress/9.0/Registration

To ensure that this is working beforehand, click Help -> register product within VS2008.

You should see text like

"You have not yet registered your copy of Visual C++ 2008 Express Edition. This product will run for 10 more days before you will be required to register it."

Close the application, delete that key, reopen, click help->register product.

The text should now say

"You have not yet registered your copy of Visual C++ 2008 Express Edition. This product will run for 30 more days before you will be required to register it."

So you have two options - delete that key manually every 30 days, or run it from a batch file that also contains a line like:

reg delete HKCU\Software\Microsoft\VCExpress\9.0\Registration /f

[Edit: User @i486 confirms on testing that this workaround works even after the expiration period has expired]

[Edit2: User @Wyatt8740 has a much more elegant way to prevent the value from reappearing.]

Just to make things even worse, in some situations, no-cache can't be used, but no-store can:

http://faindu.wordpress.com/2008/04/18/ie7-ssl-xml-flex-error-2032-stream-error/

Replacing FROM tablename with FROM (SELECT DISTINCT * FROM tablename) should give you the result you want (ignoring duplicated rows) for example:

SELECT name, COUNT(*)
FROM (SELECT DISTINCT * FROM Table1) AS T1
GROUP BY name

Result for your test data:

dave 2
mark 2

from lxml import etree
from bs4 import BeautifulSoup
soup = BeautifulSoup(open('path of your localfile.html'),'html.parser')
dom = etree.HTML(str(soup))
print dom.xpath('//*[@id="BGINP01_S1"]/section/div/font/text()')

Above used the combination of Soup object with lxml and one can extract the value using xpath

The following is a C solution using bit operators:

int numberOfOneBitsInInteger(int input) {
  int numOneBits = 0;

  int currNum = input;
  while (currNum != 0) {
    if ((currNum & 1) == 1) {
      numOneBits++;
    }
    currNum = currNum >> 1;
  }
  return numOneBits;
}

The following is a Java solution using powers of 2:

public static int numOnesInBinary(int n) {

  if (n < 0) return -1;

  int j = 0;
  while ( n > Math.pow(2, j)) j++;

  int result = 0;
  for (int i=j; i >=0; i--){
    if (n >= Math.pow(2, i)) {
        n = (int) (n - Math.pow(2,i));
        result++;    
    }
  }

  return result;
}

Don't update the primary key. It could cause a lot of problems for you keeping your data intact, if you have any other tables referencing it.

Ideally, if you want a unique field that is updateable, create a new field.

In ksh ,bash ,sh:

$ count7=0                     
$ count1=5
$ 
$ (( count7 += count1 ))
$ echo $count7
$ 5

Create the user with a password :

http://www.postgresql.org/docs/current/static/sql-createuser.html

CREATE USER name [ [ WITH ] option [ ... ] ]

where option can be:

      SUPERUSER | NOSUPERUSER
    | CREATEDB | NOCREATEDB
    | CREATEROLE | NOCREATEROLE
    | CREATEUSER | NOCREATEUSER
    | INHERIT | NOINHERIT
    | LOGIN | NOLOGIN
    | REPLICATION | NOREPLICATION
    | CONNECTION LIMIT connlimit
    | [ ENCRYPTED | UNENCRYPTED ] PASSWORD 'password'
    | VALID UNTIL 'timestamp'
    | IN ROLE role_name [, ...]
    | IN GROUP role_name [, ...]
    | ROLE role_name [, ...]
    | ADMIN role_name [, ...]
    | USER role_name [, ...]
    | SYSID uid

Then grant the user rights on a specific database :

http://www.postgresql.org/docs/current/static/sql-grant.html

Example :

grant all privileges on database db_name to someuser;

echo "$FOO"

In Rails 3, Application specific custom configuration data can be placed in the application configuration object. The configuration can be assigned in the initialization files or the environment files -- say for a given application MyApp:

MyApp::Application.config.custom_config_variable = :my_config_setting

or

Rails.configuration.custom_config_variable = :my_config_setting

To read the setting, simply call the configuration variable without setting it:

Rails.configuration.custom_config_variable
=> :my_config_setting

UPDATE Rails 4

In Rails 4 there a new way for this => http://guides.rubyonrails.org/configuring.html#custom-configuration

You can list the tags on remote repository with ls-remote, and then check if it's there. Supposing the remote reference name is origin in the following.

git ls-remote --tags origin

And you can list tags local with tag.

git tag

You can compare the results manually or in script.

Well, it doesn't get much better than that. Officially, you should use

dataGridView1.DataSource = typeof(List); 
dataGridView1.DataSource = itemStates;

It's still a "clear/reset source" kind of solution, but I have yet to find anything else that would reliably refresh the DGV data source.

I'm assuming you want to store the interestKeys in a list.

Using the org.json library:

JSONObject obj = new JSONObject("{interests : [{interestKey:Dogs}, {interestKey:Cats}]}");

List<String> list = new ArrayList<String>();
JSONArray array = obj.getJSONArray("interests");
for(int i = 0 ; i < array.length() ; i++){
    list.add(array.getJSONObject(i).getString("interestKey"));
}

Fast, simple, but maybe not always right:

>>> [x for x in mylist if x.isdigit()]
['1', '2', '3', '4']

More traditional if you need to get numbers:

new_list = []
for value in mylist:
    try:
        new_list.append(int(value))
    except ValueError:
        continue

Note: The result has integers. Convert them back to strings if needed, replacing the lines above with:

try:
    new_list.append(str(int(value)))

SELECT *
FROM LogRequests
WHERE cast(dateX as date) between '2014-05-09' and '2014-05-10';

This will select all the data between the 2 dates

You might find the git_remote_branch tool useful. It offers simple commands for creating, publishing, deleting, tracking & renaming remote branches. One nice feature is that you can ask a grb command to explain what git commands it would execute.

grb explain create my_branch github
# git_remote_branch version 0.3.0

# List of operations to do to create a new remote branch and track it locally:
git push github master:refs/heads/my_branch
git fetch github
git branch --track my_branch github/my_branch
git checkout my_branch

You'll need to use a static readonly list instead. And if you want the list to be immutable then you might want to consider using ReadOnlyCollection<T> rather than List<T>.

private static readonly ReadOnlyCollection<string> _metrics =
    new ReadOnlyCollection<string>(new[]
        {
            SourceFile.LOC,
            SourceFile.MCCABE,
            SourceFile.NOM,
            SourceFile.NOA,
            SourceFile.FANOUT,
            SourceFile.FANIN,
            SourceFile.NOPAR,
            SourceFile.NDC,
            SourceFile.CALLS
        });

public static ReadOnlyCollection<string> Metrics
{
    get { return _metrics; }
}

You can use

str1.compareTo(str2);

If str1 is lexicographically less than str2, a negative number will be returned, 0 if equal or a positive number if str1 is greater.

E.g.,

"a".compareTo("b"); // returns a negative number, here -1
"a".compareTo("a"); // returns  0
"b".compareTo("a"); // returns a positive number, here 1
"b".compareTo(null); // throws java.lang.NullPointerException

max is built in function which takes first argument an iterable (like list or tuple)

keyword argument key has it's default value None but it accept function to evaluate, consider it as wrapper which evaluates iterable based on function

Consider this example dictionary:

d = {'aim':99, 'aid': 45, 'axe': 59, 'big': 9, 'short': 995, 'sin':12, 'sword':1, 'friend':1000, 'artwork':23}

Ex:

>>> max(d.keys())
'sword'

As you can see if you only pass the iterable without kwarg(a function to key) it is returning maximum value of key(alphabetically)

Ex. Instead of finding max value of key alphabetically you might need to find max key by length of key:

>>>max(d.keys(), key=lambda x: len(x))
'artwork'

in this example lambda function is returning length of key which will be iterated hence while evaluating values instead of considering alphabetically it will keep track of max length of key and returns key which has max length

Ex.

>>> max(d.keys(), key=lambda x: d[x])
'friend'

in this example lambda function is returning value of corresponding dictionary key which has maximum value

7-Zip can be used to generate hashes for files, folders of files, and trees of folders of files. 7-Zip is small footprint and a very useful compression utility. http://7-zip.org/

The solution that worked best for me was the one written up by Nick on his blog

The basic idea of his solution is to use the Apache servers header mod and edit the .htaccess to include a FileMatch directive that the forces all *.pdf files to act as a stream instead of an attachment. While this doesn't actually involve editing HTML (as per the original question) it doesn't require any programming per se.

The first reason I preferred Nick's approach is because it allowed me to set it on a per folder basis so PDF's in one folder could still be opened in the browser while allowing others (the ones we would like users to edit and then re-upload) to be forced as downloads.

I would also like to add that there is an option with PDF's to post/submit fillable forms via an API to your servers, but that takes awhile to implement.

The second reason was because time is a consideration. Writing a PHP file handler to force the content disposition in the header() will also take less time than an API, but still longer than Nick's approach.

If you know how to turn on an Apache mod and edit the .htaccss you can get this in about 10 minutes. It requires Linux hosting (not Windows). This may not be appropriate approach for all uses as it requires high level server access to configure. As such, if you have said access it's probably because you already know how to do those two things. If not, check Nick's blog for more instructions.

An HTTP server is conceptually simple:

• Open port 80 for listening
• When contact is made, gather a little information (get mainly - you can ignore the rest for now)
• Translate the request into a file request
• Open the file and spit it back at the client

It gets more difficult depending on how much of HTTP you want to support - POST is a little more complicated, scripts, handling multiple requests, etc.

But the base is very simple.

PHP generates HTML. You may want:

echo "foo";
echo "<br />\n";
echo "bar";

This function will do as JohnFx suggested and allow for varied lengths on the arrays

Function mergeArrays(ByVal arr1 As Variant, ByVal arr2 As Variant) As Variant
    Dim holdarr As Variant
    Dim ub1 As Long
    Dim ub2 As Long
    Dim bi As Long
    Dim i As Long
    Dim newind As Long

        ub1 = UBound(arr1) + 1
        ub2 = UBound(arr2) + 1

        bi = IIf(ub1 >= ub2, ub1, ub2)

        ReDim holdarr(ub1 + ub2 - 1)

        For i = 0 To bi
            If i < ub1 Then
                holdarr(newind) = arr1(i)
                newind = newind + 1
            End If

            If i < ub2 Then
                holdarr(newind) = arr2(i)
                newind = newind + 1
            End If
        Next i

        mergeArrays = holdarr
End Function

Java makes regex too complicated and it does not follow the perl-style. Take a look at MentaRegex to see how you can accomplish that in a single line of Java code:

String[] matches = match("aa11bb22", "/(\\d+)/g" ); // => ["11", "22"]

I have a reliable way to generate SQL inserts batly,and you can modify partial parameters in processing.It helps me a lot in my work, for example, copy one hundreds data to database with incompatible structure and fields count. IntellIJ DataGrip , the powerful tool i use. DG can batly receive data from WPS office or MS Excel by column or line. after copying, DG can export data as SQL inserts.

Use the os module:

import os
os.chdir('..')

should work

1. python.exe -i works but got issues in exiting from the interactive mode by sending "^Z" (CTRL+Z). So, seem better to use winpty python.exe in Git Bash for Windows.
   

2. Use ~/bin directory to make a wrap/reference file (like ~/bin/python) which will be accessible everywhere (you may use different version reference like ~/bin/python37).
   Code inside the file:

#!/usr/bin/env bash
# maybe declare env vars here like
# export PYTHONHOME=/c/Users/%USERNAME%/.python/Python36
# export PATH="${PATH}:/c/Users/%USERNAME%/.python/Python36"

# replace %USERNAME%,
# or use "~" instead of "/c/Users/%USERNAME%" if it works
winpty /c/Users/%USERNAME%/.python/Python36/python.exe ${@}

I just don't like these "magic" aliases which you're always forgetting where it's coming from, and sometimes leads to issues in some cases.

3. Use ~/bin/python file and -i parameter:

#!/usr/bin/env bash
if [ -z "${@}" ]; then
    # empty args, use interactive mode
    /c/Users/%USERNAME%/.python/Python36/python.exe -i
else
    /c/Users/%USERNAME%/.python/Python36/python.exe ${@}
fi

printf("\nmaximum of %d and %d is = %d",a,b,c);

If you are floating the elements you can reverse the order

i.e. float: right; instead of float: left;

And then use this method to select the first-child of a class.

/* 1: Apply style to ALL instances */
#header .some-class {
  padding-right: 0;
}
/* 2: Remove style from ALL instances except FIRST instance */
#header .some-class~.some-class {
  padding-right: 20px;
}

This is actually applying the class to the LAST instance only because it's now in reversed order.

Here is a working example for you:

<!doctype html>
<head><title>CSS Test</title>
<style type="text/css">
.some-class { margin: 0; padding: 0 20px; list-style-type: square; }
.lfloat { float: left; display: block; }
.rfloat { float: right; display: block; }
/* apply style to last instance only */
#header .some-class {
  border: 1px solid red;
  padding-right: 0;
}
#header .some-class~.some-class {
  border: 0;
  padding-right: 20px;
}
</style>
</head>
<body>
<div id="header">
  <img src="some_image" title="Logo" class="lfloat no-border"/>
  <ul class="some-class rfloat">
    <li>List 1-1</li>
    <li>List 1-2</li>
    <li>List 1-3</li>
  </ul>
  <ul class="some-class rfloat">
    <li>List 2-1</li>
    <li>List 2-2</li>
    <li>List 2-3</li>
  </ul>
  <ul class="some-class rfloat">
    <li>List 3-1</li>
    <li>List 3-2</li>
    <li>List 3-3</li>
  </ul>
  <img src="some_other_img" title="Icon" class="rfloat no-border"/>
</div>
</body>
</html>

@JAB's answer is fast and concise. But it changes the DataFrame you are trying to sort, which you may or may not want.

_{(Note: You almost certainly will want it, because your date columns should be dates, not strings!)}

In the unlikely event that you don't want to change the dates into dates, you can also do it a different way.

First, get the index from your sorted Date column:

In [25]: pd.to_datetime(df.Date).order().index
Out[25]: Int64Index([0, 2, 1], dtype='int64')

Then use it to index your original DataFrame, leaving it untouched:

In [26]: df.ix[pd.to_datetime(df.Date).order().index]
Out[26]: 
        Date Symbol
0 2015-02-20      A
2 2015-08-21      A
1 2016-01-15      A

Magic!

Note: for Pandas versions 0.20.0 and later, use loc instead of ix, which is now deprecated.

Spring-boot framework allows us to provide YAML files as a replacement for the .properties file and it is convenient.The keys in property files can be provided in YAML format in application.yml file in the resource folder and spring-boot will automatically take it up.Keep in mind that the yaml format has to keep the spaces correct for the value to be read correctly.

You can use the @Value("${property}") to inject the values from the YAML files. Also Spring.active.profiles can be given to differentiate between different YAML for different environments for convenient deployment.

For testing purposes, the test YAML file can be named like application-test.yml and placed in the resource folder of the test directory.

If you are specifying the application-test.yml and provide the spring test profile in the .yml, then you can use the @ActiveProfiles('test') annotation to direct spring to take the configurations from the application-test.yml that you have specified.

@RunWith(SpringRunner.class)
@SpringBootTest(classes = ApplicationTest.class)
@ActiveProfiles("test")
public class MyTest {
 ...
}

If you are using JUnit 5 then no need for other annotations as @SpringBootTest already include the springrunner annotation. Keeping a separate main ApplicationTest.class enables us to provide separate configuration classes for tests and we can prevent the default configuration beans from loading by excluding them from a component scan in the test main class. You can also provide the profile to be loaded there.

@SpringBootApplication(exclude=SecurityAutoConfiguration.class)
public class ApplicationTest {
 
    public static void main(String[] args) {
        SpringApplication.run(ApplicationTest.class, args);
    }
}

Here is the link for Spring documentation regarding the use of YAML instead of .properties file(s): https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html

Don't hesitate to watch heap to see memory leaks in event handlers keeping a reference to the element with a closure and the element keeping a reference to the event handler.

Garbage collector do not like circular references.

Usual memory leak case: admit an object has a ref to an element. That element has a ref to the handler. And the handler has a ref to the object. The object has refs to a lot of other objects. This object was part of a collection you think you have thrown away by unreferencing it from your collection. => the whole object and all it refers will remain in memory till page exit. => you have to think about a complete killing method for your object class or trust a mvc framework for example.

Moreover, don't hesitate to use the Retaining tree part of Chrome dev tools.

You can do like

$result= file_get_contents(site_url('[ADDRESS TO CONTROLLER FUNCTION]'));

Replace [ADDRESS TO CONTROLLER FUNCTION] by the way we use in site_url();

You need to echo output in controller function instead of return.

It is possible using ConfigTransform build target available as a Nuget package - https://www.nuget.org/packages/CodeAssassin.ConfigTransform/

All "web.*.config" transform files will be transformed and output as a series of "web.*.config.transformed" files in the build output directory regardless of the chosen build configuration.

The same applies to "app.*.config" transform files in non-web projects.

and then adding the following target to your *.csproj.

<Target Name="TransformActiveConfiguration" Condition="Exists('$(ProjectDir)/Web.$(Configuration).config')" BeforeTargets="Compile" >
    <TransformXml Source="$(ProjectDir)/Web.Config" Transform="$(ProjectDir)/Web.$(Configuration).config" Destination="$(TargetDir)/Web.config" />
</Target>

An enhancement of the hacky idea by Nick Craver to put custom HTML in a jquery dialog title:

var newtitle= '<b>HTML TITLE</b>';
$(".selectorUsedToCreateTheDialog").parent().find("span.ui-dialog-title").html(newtitle);

declare @cur cursor
declare @idx int       
declare @Approval_No varchar(50) 

declare @ReqNo varchar(100)
declare @M_Id  varchar(100)
declare @Mail_ID varchar(100)
declare @temp  table
(
val varchar(100)
)
declare @temp2  table
(
appno varchar(100),
mailid varchar(100),
userod varchar(100)
)


    declare @slice varchar(8000)       
    declare @String varchar(100)
    --set @String = '1200096,1200095,1200094,1200093,1200092,1200092'
set @String = '20131'

bool is just a macro that expands to _Bool. You can use _Bool with no #include very much like you can use int or double; it is a C99 keyword.

The macro is defined in <stdbool.h> along with 3 other macros.

The macros defined are

• bool: macro expands to _Bool
• false: macro expands to 0
• true: macro expands to 1
• __bool_true_false_are_defined: macro expands to 1

DEMO

There's a really cool function called document.elementFromPoint which does what it sounds like.

What we need is to find the x and y coords of the mouse and then call it using those values:

var x = event.clientX, y = event.clientY,
    elementMouseIsOver = document.elementFromPoint(x, y);

Don’t fall into the trap of thinking a library should prescribe how to do everything. If you want to do something with a timeout in JavaScript, you need to use setTimeout. There is no reason why Redux actions should be any different.

Redux does offer some alternative ways of dealing with asynchronous stuff, but you should only use those when you realize you are repeating too much code. Unless you have this problem, use what the language offers and go for the simplest solution.

Writing Async Code Inline

This is by far the simplest way. And there’s nothing specific to Redux here.

store.dispatch({ type: 'SHOW_NOTIFICATION', text: 'You logged in.' })
setTimeout(() => {
  store.dispatch({ type: 'HIDE_NOTIFICATION' })
}, 5000)

Similarly, from inside a connected component:

this.props.dispatch({ type: 'SHOW_NOTIFICATION', text: 'You logged in.' })
setTimeout(() => {
  this.props.dispatch({ type: 'HIDE_NOTIFICATION' })
}, 5000)

The only difference is that in a connected component you usually don’t have access to the store itself, but get either dispatch() or specific action creators injected as props. However this doesn’t make any difference for us.

If you don’t like making typos when dispatching the same actions from different components, you might want to extract action creators instead of dispatching action objects inline:

// actions.js
export function showNotification(text) {
  return { type: 'SHOW_NOTIFICATION', text }
}
export function hideNotification() {
  return { type: 'HIDE_NOTIFICATION' }
}

// component.js
import { showNotification, hideNotification } from '../actions'

this.props.dispatch(showNotification('You just logged in.'))
setTimeout(() => {
  this.props.dispatch(hideNotification())
}, 5000)

Or, if you have previously bound them with connect():

this.props.showNotification('You just logged in.')
setTimeout(() => {
  this.props.hideNotification()
}, 5000)

So far we have not used any middleware or other advanced concept.

Extracting Async Action Creator

The approach above works fine in simple cases but you might find that it has a few problems:

• It forces you to duplicate this logic anywhere you want to show a notification.
• The notifications have no IDs so you’ll have a race condition if you show two notifications fast enough. When the first timeout finishes, it will dispatch HIDE_NOTIFICATION, erroneously hiding the second notification sooner than after the timeout.

To solve these problems, you would need to extract a function that centralizes the timeout logic and dispatches those two actions. It might look like this:

// actions.js
function showNotification(id, text) {
  return { type: 'SHOW_NOTIFICATION', id, text }
}
function hideNotification(id) {
  return { type: 'HIDE_NOTIFICATION', id }
}

let nextNotificationId = 0
export function showNotificationWithTimeout(dispatch, text) {
  // Assigning IDs to notifications lets reducer ignore HIDE_NOTIFICATION
  // for the notification that is not currently visible.
  // Alternatively, we could store the timeout ID and call
  // clearTimeout(), but we’d still want to do it in a single place.
  const id = nextNotificationId++
  dispatch(showNotification(id, text))

  setTimeout(() => {
    dispatch(hideNotification(id))
  }, 5000)
}

Now components can use showNotificationWithTimeout without duplicating this logic or having race conditions with different notifications:

// component.js
showNotificationWithTimeout(this.props.dispatch, 'You just logged in.')

// otherComponent.js
showNotificationWithTimeout(this.props.dispatch, 'You just logged out.')    

Why does showNotificationWithTimeout() accept dispatch as the first argument? Because it needs to dispatch actions to the store. Normally a component has access to dispatch but since we want an external function to take control over dispatching, we need to give it control over dispatching.

If you had a singleton store exported from some module, you could just import it and dispatch directly on it instead:

// store.js
export default createStore(reducer)

// actions.js
import store from './store'

// ...

let nextNotificationId = 0
export function showNotificationWithTimeout(text) {
  const id = nextNotificationId++
  store.dispatch(showNotification(id, text))

  setTimeout(() => {
    store.dispatch(hideNotification(id))
  }, 5000)
}

// component.js
showNotificationWithTimeout('You just logged in.')

// otherComponent.js
showNotificationWithTimeout('You just logged out.')    

This looks simpler but we don’t recommend this approach. The main reason we dislike it is because it forces store to be a singleton. This makes it very hard to implement server rendering. On the server, you will want each request to have its own store, so that different users get different preloaded data.

A singleton store also makes testing harder. You can no longer mock a store when testing action creators because they reference a specific real store exported from a specific module. You can’t even reset its state from outside.

So while you technically can export a singleton store from a module, we discourage it. Don’t do this unless you are sure that your app will never add server rendering.

Getting back to the previous version:

// actions.js

// ...

let nextNotificationId = 0
export function showNotificationWithTimeout(dispatch, text) {
  const id = nextNotificationId++
  dispatch(showNotification(id, text))

  setTimeout(() => {
    dispatch(hideNotification(id))
  }, 5000)
}

// component.js
showNotificationWithTimeout(this.props.dispatch, 'You just logged in.')

// otherComponent.js
showNotificationWithTimeout(this.props.dispatch, 'You just logged out.')    

This solves the problems with duplication of logic and saves us from race conditions.

Thunk Middleware

For simple apps, the approach should suffice. Don’t worry about middleware if you’re happy with it.

In larger apps, however, you might find certain inconveniences around it.

For example, it seems unfortunate that we have to pass dispatch around. This makes it trickier to separate container and presentational components because any component that dispatches Redux actions asynchronously in the manner above has to accept dispatch as a prop so it can pass it further. You can’t just bind action creators with connect() anymore because showNotificationWithTimeout() is not really an action creator. It does not return a Redux action.

In addition, it can be awkward to remember which functions are synchronous action creators like showNotification() and which are asynchronous helpers like showNotificationWithTimeout(). You have to use them differently and be careful not to mistake them with each other.

This was the motivation for finding a way to “legitimize” this pattern of providing dispatch to a helper function, and help Redux “see” such asynchronous action creators as a special case of normal action creators rather than totally different functions.

If you’re still with us and you also recognize as a problem in your app, you are welcome to use the Redux Thunk middleware.

In a gist, Redux Thunk teaches Redux to recognize special kinds of actions that are in fact functions:

import { createStore, applyMiddleware } from 'redux'
import thunk from 'redux-thunk'

const store = createStore(
  reducer,
  applyMiddleware(thunk)
)

// It still recognizes plain object actions
store.dispatch({ type: 'INCREMENT' })

// But with thunk middleware, it also recognizes functions
store.dispatch(function (dispatch) {
  // ... which themselves may dispatch many times
  dispatch({ type: 'INCREMENT' })
  dispatch({ type: 'INCREMENT' })
  dispatch({ type: 'INCREMENT' })

  setTimeout(() => {
    // ... even asynchronously!
    dispatch({ type: 'DECREMENT' })
  }, 1000)
})

When this middleware is enabled, if you dispatch a function, Redux Thunk middleware will give it dispatch as an argument. It will also “swallow” such actions so don’t worry about your reducers receiving weird function arguments. Your reducers will only receive plain object actions—either emitted directly, or emitted by the functions as we just described.

This does not look very useful, does it? Not in this particular situation. However it lets us declare showNotificationWithTimeout() as a regular Redux action creator:

// actions.js
function showNotification(id, text) {
  return { type: 'SHOW_NOTIFICATION', id, text }
}
function hideNotification(id) {
  return { type: 'HIDE_NOTIFICATION', id }
}

let nextNotificationId = 0
export function showNotificationWithTimeout(text) {
  return function (dispatch) {
    const id = nextNotificationId++
    dispatch(showNotification(id, text))

    setTimeout(() => {
      dispatch(hideNotification(id))
    }, 5000)
  }
}

Note how the function is almost identical to the one we wrote in the previous section. However it doesn’t accept dispatch as the first argument. Instead it returns a function that accepts dispatch as the first argument.

How would we use it in our component? Definitely, we could write this:

// component.js
showNotificationWithTimeout('You just logged in.')(this.props.dispatch)

We are calling the async action creator to get the inner function that wants just dispatch, and then we pass dispatch.

However this is even more awkward than the original version! Why did we even go that way?

Because of what I told you before. If Redux Thunk middleware is enabled, any time you attempt to dispatch a function instead of an action object, the middleware will call that function with dispatch method itself as the first argument.

So we can do this instead:

// component.js
this.props.dispatch(showNotificationWithTimeout('You just logged in.'))

Finally, dispatching an asynchronous action (really, a series of actions) looks no different than dispatching a single action synchronously to the component. Which is good because components shouldn’t care whether something happens synchronously or asynchronously. We just abstracted that away.

Notice that since we “taught” Redux to recognize such “special” action creators (we call them thunk action creators), we can now use them in any place where we would use regular action creators. For example, we can use them with connect():

// actions.js

function showNotification(id, text) {
  return { type: 'SHOW_NOTIFICATION', id, text }
}
function hideNotification(id) {
  return { type: 'HIDE_NOTIFICATION', id }
}

let nextNotificationId = 0
export function showNotificationWithTimeout(text) {
  return function (dispatch) {
    const id = nextNotificationId++
    dispatch(showNotification(id, text))

    setTimeout(() => {
      dispatch(hideNotification(id))
    }, 5000)
  }
}

// component.js

import { connect } from 'react-redux'

// ...

this.props.showNotificationWithTimeout('You just logged in.')

// ...

export default connect(
  mapStateToProps,
  { showNotificationWithTimeout }
)(MyComponent)

Reading State in Thunks

Usually your reducers contain the business logic for determining the next state. However, reducers only kick in after the actions are dispatched. What if you have a side effect (such as calling an API) in a thunk action creator, and you want to prevent it under some condition?

Without using the thunk middleware, you’d just do this check inside the component:

// component.js
if (this.props.areNotificationsEnabled) {
  showNotificationWithTimeout(this.props.dispatch, 'You just logged in.')
}

However, the point of extracting an action creator was to centralize this repetitive logic across many components. Fortunately, Redux Thunk offers you a way to read the current state of the Redux store. In addition to dispatch, it also passes getState as the second argument to the function you return from your thunk action creator. This lets the thunk read the current state of the store.

let nextNotificationId = 0
export function showNotificationWithTimeout(text) {
  return function (dispatch, getState) {
    // Unlike in a regular action creator, we can exit early in a thunk
    // Redux doesn’t care about its return value (or lack of it)
    if (!getState().areNotificationsEnabled) {
      return
    }

    const id = nextNotificationId++
    dispatch(showNotification(id, text))

    setTimeout(() => {
      dispatch(hideNotification(id))
    }, 5000)
  }
}

Don’t abuse this pattern. It is good for bailing out of API calls when there is cached data available, but it is not a very good foundation to build your business logic upon. If you use getState() only to conditionally dispatch different actions, consider putting the business logic into the reducers instead.

Next Steps

Now that you have a basic intuition about how thunks work, check out Redux async example which uses them.

You may find many examples in which thunks return Promises. This is not required but can be very convenient. Redux doesn’t care what you return from a thunk, but it gives you its return value from dispatch(). This is why you can return a Promise from a thunk and wait for it to complete by calling dispatch(someThunkReturningPromise()).then(...).

You may also split complex thunk action creators into several smaller thunk action creators. The dispatch method provided by thunks can accept thunks itself, so you can apply the pattern recursively. Again, this works best with Promises because you can implement asynchronous control flow on top of that.

For some apps, you may find yourself in a situation where your asynchronous control flow requirements are too complex to be expressed with thunks. For example, retrying failed requests, reauthorization flow with tokens, or a step-by-step onboarding can be too verbose and error-prone when written this way. In this case, you might want to look at more advanced asynchronous control flow solutions such as Redux Saga or Redux Loop. Evaluate them, compare the examples relevant to your needs, and pick the one you like the most.

Finally, don’t use anything (including thunks) if you don’t have the genuine need for them. Remember that, depending on the requirements, your solution might look as simple as

store.dispatch({ type: 'SHOW_NOTIFICATION', text: 'You logged in.' })
setTimeout(() => {
  store.dispatch({ type: 'HIDE_NOTIFICATION' })
}, 5000)

Don’t sweat it unless you know why you’re doing this.

You are searching for a multimap, and indeed both commons-collections and Guava have several implementations for that. Multimaps allow for multiple keys by maintaining a collection of values per key, i.e. you can put a single object into the map, but you retrieve a collection.

If you can use Java 5, I would prefer Guava's Multimap as it is generics-aware.

function in_array(what, where) {
    var a=false;
    for (var i=0; i<where.length; i++) {
        if(what == where[i]) {
            a=true;
            break;
        }
    }
    return a;
}

You can use:

SET PASSWORD FOR 'root' = PASSWORD('elephant7');

or, in latest versions:

SET PASSWORD FOR root = 'elephant7' 

You can also use:

UPDATE user SET password=password('elephant7') WHERE user='root';

but in Mysql 5.7 the field password is no more there, and you have to use:

To improve upon the answer given by derobert,

You can determine what your OS connection limit is by catting nf_conntrack_max.

For example: cat /proc/sys/net/netfilter/nf_conntrack_max

You can use the following script to count the number of tcp connections to a given range of tcp ports. By default 1-65535.

This will confirm whether or not you are maxing out your OS connection limit.

Here's the script.

#!/bin/bash
OS=$(uname)

case "$OS" in
    'SunOS')
            AWK=/usr/bin/nawk
            ;;
    'Linux')
            AWK=/bin/awk
            ;;
    'AIX')
            AWK=/usr/bin/awk
            ;;
esac

netstat -an | $AWK -v start=1 -v end=65535 ' $NF ~ /TIME_WAIT|ESTABLISHED/ && $4 !~ /127\.0\.0\.1/ {
    if ($1 ~ /\./)
            {sip=$1}
    else {sip=$4}

    if ( sip ~ /:/ )
            {d=2}
    else {d=5}

    split( sip, a, /:|\./ )

    if ( a[d] >= start && a[d] <= end ) {
            ++connections;
            }
    }
    END {print connections}'

I'm pretty sure you can completely delete the <stuff> , which will generate a warning and you can use an, @ suppress warnings. If you really want it to be generic, but to use any of its elements you will have to do type casting. For instance, I made a simple bubble sort function and it uses a generic type when sorting the list, which is actually an array of Comparable in this case. If you wish to use an item, do something like: System.out.println((Double)arrayOfDoubles[0] + (Double)arrayOfDoubles[1]); because I stuffed Double(s) into Comparable(s) which is polymorphism since all Double(s) inherit from Comparable to allow easy sorting through Collections.sort()

        //INDENT TO DISPLAY CODE ON STACK-OVERFLOW
@SuppressWarnings("unchecked")
public static void simpleBubbleSort_ascending(@SuppressWarnings("rawtypes") Comparable[] arrayOfDoubles)
{
//VARS
    //looping
    int end      =      arrayOfDoubles.length - 1;//the last index in our loops
    int iterationsMax = arrayOfDoubles.length - 1;

    //swapping
    @SuppressWarnings("rawtypes")
    Comparable tempSwap = 0.0;//a temporary double used in the swap process
    int elementP1 = 1;//element + 1,   an index for comparing and swapping


//CODE
    //do up to 'iterationsMax' many iterations
    for (int iteration = 0; iteration < iterationsMax; iteration++)
    {
        //go through each element and compare it to the next element
        for (int element = 0; element < end; element++)
        {
            elementP1 = element + 1;

            //if the elements need to be swapped, swap them
            if (arrayOfDoubles[element].compareTo(arrayOfDoubles[elementP1])==1)
            {
                //swap
                tempSwap = arrayOfDoubles[element];
                arrayOfDoubles[element] = arrayOfDoubles[elementP1];
                arrayOfDoubles[elementP1] = tempSwap;
            }
        }
    }
}//END public static void simpleBubbleSort_ascending(double[] arrayOfDoubles)

You could rely on wget which usually handles ftp get properly (at least in my own experience). For example:

wget -r ftp://user:[email protected]/

You can also use -m which is suitable for mirroring. It is currently equivalent to -r -N -l inf.

If you've some special characters in the credential details, you can specify the --user and --password arguments to get it to work. Example with custom login with specific characters:

wget -r --user="user@login" --password="Pa$$wo|^D" ftp://server.com/

As pointed out by @asmaier, watch out that even if -r is for recursion, it has a default max level of 5:

-r
--recursive
    Turn on recursive retrieving.

-l depth
--level=depth
    Specify recursion maximum depth level depth.  The default maximum depth is 5.

If you don't want to miss out subdirs, better use the mirroring option, -m:

-m
--mirror
    Turn on options suitable for mirroring.  This option turns on recursion and time-stamping, sets infinite
    recursion depth and keeps FTP directory listings.  It is currently equivalent to -r -N -l inf
    --no-remove-listing.

Here is the method which is used in Commerce SagePay and in Commerce Paypoint Drupal modules which basically compares document.location.href with the old value by first loading its own iframe, then external one.

So basically the idea is to load the blank page as a placeholder with its own JS code and hidden form. Then parent JS code will submit that hidden form where its #action points to the external iframe. Once the redirect/submit happens, the JS code which still running on that page can track your document.location.href value changes.

Here is example JS used in iframe:

;(function($) {
  Drupal.behaviors.commercePayPointIFrame = {
    attach: function (context, settings) {
      if (top.location != location) {
        $('html').hide();
        top.location.href = document.location.href;
      }
    }
  }
})(jQuery);

And here is JS used in parent page:

;(function($) {
  /**
   * Automatically submit the hidden form that points to the iframe.
   */
  Drupal.behaviors.commercePayPoint = {
    attach: function (context, settings) {
      $('div.payment-redirect-form form', context).submit();
      $('div.payment-redirect-form #edit-submit', context).hide();
      $('div.payment-redirect-form .checkout-help', context).hide();
    }
  }
})(jQuery);

Then in temporary blank landing page you need to include the form which will redirect to the external page.

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

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

export default QuestionSet;

You can still use that method with associative arrays:

$keys = array_keys($array);
for ($i = 0, $l = count($array); $i < $l; ++$i) {
    $key = $array[$i];
    $value = $array[$key];
    $isLastItem = ($i == ($l - 1));
    // do stuff
}

// or this way...

$i = 0;
$l = count($array);
foreach ($array as $key => $value) {
    $isLastItem = ($i == ($l - 1));
    // do stuff
    ++$i;
}

The visible width of an element is width + padding + border + outline, so it seems that you are forgetting about the border on the input element. That is, to say, that the default border width for an input element on most (some?) browsers is actually calculated as 2px, not one. Hence your input is appearing as 2px wider. Try explicitly setting the border-width on the input, or making your div wider.

How do I have a div not take up space until it is timed to come in (using CSS for the timing.)

Here is my solution to the same problem.

Moreover I have an onclick on the last frame loading another slideshow, and it must not be clickable until the last frame is visible.

Basically my solution is to keep the div 1 pixel high using a scale(0.001), zooming it when I need it. If you don't like the zoom effect you can restore the opacity to 1 after zooming the slide.

#Slide_TheEnd {

    -webkit-animation-delay: 240s;
    animation-delay: 240s;

    -moz-animation-timing-function: linear;
    -webkit-animation-timing-function: linear;
    animation-timing-function: linear;

    -moz-animation-duration: 20s;
    -webkit-animation-duration: 20s;
    animation-duration: 20s;

    -moz-animation-name: Slide_TheEnd;
    -webkit-animation-name: Slide_TheEnd;
    animation-name: Slide_TheEnd;

    -moz-animation-iteration-count: 1;
    -webkit-animation-iteration-count: 1;
    animation-iteration-count: 1;

    -moz-animation-direction: normal;
    -webkit-animation-direction: normal;
    animation-direction: normal;

    -moz-animation-fill-mode: forwards;
    -webkit-animation-fill-mode: forwards;
    animation-fill-mode: forwards;

    transform: scale(0.001);
    background: #cf0;
    text-align: center;
    font-size: 10vh;
    opacity: 0;
}

@-moz-keyframes Slide_TheEnd {
    0% { opacity: 0;  transform: scale(0.001); }
    10% { opacity: 1; transform: scale(1); }
    95% { opacity: 1; transform: scale(1); }
    100% { opacity: 0;  transform: scale(0.001); }
}

Other keyframes are removed for the sake of bytes. Please disregard the odd coding, it is made by a php script picking values from an array and str_replacing a template: I'm too lazy to retype everything for every proprietary prefix on a 100+ divs slideshow.

strSearch in this case is probably null (not simply empty).

Try using

String.IsNullOrEmpty(strSearch)

if you are just trying to determine if the string doesn't have any contents.

I looked into this a bit more and the actual problem seems to be with assigning initial to page width under the print media rule. It seems like in Chrome width: initial on the .page element results in scaling of the page content if no specific length value is defined for width on any of the parent elements (width: initial in this case resolves to width: auto ... but actually any value smaller than the size defined under the @page rule causes the same issue).

So not only the content is now too long for the page (by about 2cm), but also the page padding will be slightly more than the initial 2cm and so on (it seems to render the contents under width: auto to the width of ~196mm and then scale the whole content up to the width of 210mm ~ but strangely exactly the same scaling factor is applied to contents with any width smaller than 210mm).

To fix this problem you can simply in the print media rule assign the A4 paper width and hight to html, body or directly to .page and in this case avoid the initial keyword.

DEMO

@page {
  size: A4;
  margin: 0;
}
@media print {
  html, body {
    width: 210mm;
    height: 297mm;
  }
  /* ... the rest of the rules ... */
}

^{This seems to keep everything else the way it is in your original CSS and fix the problem in Chrome (tested in different versions of Chrome under Windows, OS X and Ubuntu).}

jQuery .removeClass() documentation.

One or more CSS classes to remove from the elements, these are separated by spaces.

There's actually seven variants of this:

    char   description          unicode   html       html entity    utf-8

    ·      Middle Dot           U+00B7    ·     ·       C2 B7
    ·      Greek Ano Teleia     U+0387    ·                    CE 87
    •      Bullet               U+2022    •    •         E2 80 A2
    ‧      Hyphenation Point    U+2027    ₁                   E2 80 A7
    ∙      Bullet Operator      U+2219    ∙                   E2 88 99
    ●      Black Circle         U+25CF    ●                   E2 97 8F
    ⬤     Black Large Circle   U+2B24    ⬤                  E2 AC A4

Depending on your viewing application or font, the Bullet Operator may seem very similar to either the Middle Dot or the Bullet.

I thought of

 SELECT LENGTH('123-345-566') - LENGTH(REPLACE('123-345-566', '-', '')) FROM DUAL;

If you want to extend the amount of time permitted for an ASP.NET script to execute then increase the Server.ScriptTimeout value. The default is 90 seconds for .NET 1.x and 110 seconds for .NET 2.0 and later.

For example:

// Increase script timeout for current page to five minutes
Server.ScriptTimeout = 300;

This value can also be configured in your web.config file in the httpRuntime configuration element:

<!-- Increase script timeout to five minutes -->
<httpRuntime executionTimeout="300" 
  ... other configuration attributes ...
/>

Please note according to the MSDN documentation:

"This time-out applies only if the debug attribute in the compilation element is False. Therefore, if the debug attribute is True, you do not have to set this attribute to a large value in order to avoid application shutdown while you are debugging."

If you've already done this but are finding that your session is expiring then increase the ASP.NET HttpSessionState.Timeout value:

For example:

// Increase session timeout to thirty minutes
Session.Timeout = 30;

This value can also be configured in your web.config file in the sessionState configuration element:

<configuration>
  <system.web>
    <sessionState 
      mode="InProc"
      cookieless="true"
      timeout="30" />
  </system.web>
</configuration>

If your script is taking several minutes to execute and there are many concurrent users then consider changing the page to an Asynchronous Page. This will increase the scalability of your application.

The other alternative, if you have administrator access to the server, is to consider this long running operation as a candidate for implementing as a scheduled task or a windows service.

A virtual-table(vtable) is made for each Class having one or more 'virtual-functions'. Whenever an Object is created of such class, it contains a 'virtual-pointer' which points to the base of corresponding vtable. Whenever there is a virtual function call, the vtable is used to resolve to the function address. Constructor can not be virtual, because when constructor of a class is executed there is no vtable in the memory, means no virtual pointer defined yet. Hence the constructor should always be non-virtual.

// I'd modify this slightly to be more resilient to a bad parameter
// it will handle your case and better handle other cases given to it:

int index = 25;

if (index >= 0 && index < array.Length)
{
    // Array element found
}

Viewport units for CSS

1vw = 1% of viewport width
1vh = 1% of viewport height

This way, you don't have to write many different media queries or javascript.

If you prefer JS

window.innerWidth;
window.innerHeight;

Here is another way you can change the selected option of a <select> element in javascript. You can use

document.getElementById('salesperson').selectedIndex=1;

Setting it to 1 will make the second element of the dropdown selected. The select element index start from 0.

Here is a sample code. Check if you can use this type of approach:

<html>
<head>
<script language="javascript">

function changeSelected() { 
document.getElementById('salesperson').selectedIndex=1;

} 

</script>
</head>
<body>
<form name="f1">

<select id="salesperson" > 
   <option value"">james</option>
   <option value"">john</option>  
</select> 
<input type="button" value="Change Selected" onClick="changeSelected();">

</form>
</body>
</html>

We can resolve this problem in Spring-Apache-tomcat environment by adding one single line in RequestInterceptor method -

//before the actual handler will be executed
public boolean preHandle(HttpServletRequest request,
HttpServletResponse response, Object handler)
throws Exception {

// Some logic

// below statement ensures IE trusts the page formatting and will render it acc. to IE 8 standard.
response.addHeader("X-UA-Compatible", "IE=8"); 

return true;
}

Reference from - How to create filter and modify response header It covers how we can resolve this problem via a RequestInterceptor (Spring).

I know this reply is too late, I had the same issue and i was adding the System.Net.Http.Formatting.Extension Nuget, after checking here and there I found that the Nuget is added but the System.Net.Http.Formatting.dll was not added to the references, I just reinstalled the Nuget

By using this way you can get the list of selected records.

GregorianCalendar gregorianCalendar = new GregorianCalendar();
Criteria cri = session.createCriteria(ProjectActivities.class);
cri.add(Restrictions.ge("EffectiveFrom", gregorianCalendar.getTime()));
List list = cri.list();

All the Records will be generated into list which are greater than or equal to '08-Oct-2012' or else pass the date of user acceptance date at 2nd parameter of Restrictions (gregorianCalendar.getTime()) of criteria to get the records.

I used this videocast to set up my GoDaddy domain with Heroku, and it worked perfectly. Very clear and well explained.

Note: Skip the part about CNAME yourdomain.com. (note the .) and the heroku addons:add "custom domains"

http://blog.heroku.com/archives/2009/10/7/heroku_casts_setting_up_custom_domains/

To summarize the video:

1) on GoDaddy and create a CNAME with

Alias Name: www
Host Name: proxy.heroku.com

2) check that your domain has propagated by typing host www.yourdomain.com on the command line

3) run heroku domains:add www.yourdomain.com

4) run heroku domains:add yourdomain.com

It worked for me after these steps. Hope it works for you too!

UPDATE: things have changed, check out this post Heroku/GoDaddy: send naked domain to www

The Java Date and Calendar classes are considered by many to be poorly designed. You should take a look at Joda Time, a library commonly used in lieu of Java's built-in date libraries.

The equivalent of DateTime.Now in Joda Time is:

DateTime dt = new DateTime();

Update

As noted in the comments, the latest versions of Joda Time have a DateTime.now() method, so:

DateTime dt = DateTime.now();
