This worked for me:

using System.ComponentModel.DataAnnotations;

[Key]
public int ID { get; set; }

Update: I have found a better/proper way to solve this problem using a BehaviorSubject or an Observable rather than an EventEmitter. Please see this answer: https://stackoverflow.com/a/35568924/215945

Also, the Angular docs now have a cookbook example that uses a Subject.

Original/outdated/wrong answer: again, don't use an EventEmitter in a service. That is an anti-pattern.

Using beta.1... NavService contains the EventEmiter. Component Navigation emits events via the service, and component ObservingComponent subscribes to the events.

nav.service.ts

import {EventEmitter} from 'angular2/core';
export class NavService {
  navchange: EventEmitter<number> = new EventEmitter();
  constructor() {}
  emitNavChangeEvent(number) {
    this.navchange.emit(number);
  }
  getNavChangeEmitter() {
    return this.navchange;
  }
}

components.ts

import {Component} from 'angular2/core';
import {NavService} from '../services/NavService';

@Component({
  selector: 'obs-comp',
  template: `obs component, item: {{item}}`
})
export class ObservingComponent {
  item: number = 0;
  subscription: any;
  constructor(private navService:NavService) {}
  ngOnInit() {
    this.subscription = this.navService.getNavChangeEmitter()
      .subscribe(item => this.selectedNavItem(item));
  }
  selectedNavItem(item: number) {
    this.item = item;
  }
  ngOnDestroy() {
    this.subscription.unsubscribe();
  }
}

@Component({
  selector: 'my-nav',
  template:`
    <div class="nav-item" (click)="selectedNavItem(1)">nav 1 (click me)</div>
    <div class="nav-item" (click)="selectedNavItem(2)">nav 2 (click me)</div>
  `,
})
export class Navigation {
  item = 1;
  constructor(private navService:NavService) {}
  selectedNavItem(item: number) {
    console.log('selected nav item ' + item);
    this.navService.emitNavChangeEvent(item);
  }
}

Value cannot be null. Parameter name: source

Above error comes in situation when you are querying the collection which is null.

For demonstration below code will result in such an exception.

Console.WriteLine("Hello World");
IEnumerable<int> list = null;
list.Where(d => d ==4).FirstOrDefault();

Here is the output of the above code.

Hello World Run-time exception (line 11): Value cannot be null. Parameter name: source

Stack Trace:

[System.ArgumentNullException: Value cannot be null. Parameter name: source] at Program.Main(): line 11

In your case ListMetadataKor is null. Here is the fiddle if you want to play around.

What is the target platform of your application? I think you should set the platform to x86, do not set it to Any CPU.

This way you check if the string is not null and not empty, also considering the empty spaces:

boolean isEmpty = str == null || str.trim().length() == 0;
if (isEmpty) {
    // handle the validation
}

The exit() function is a type of function with a return type without an argument. It's defined by the stdlib header file.

You need to use ( exit(0) or exit(EXIT_SUCCESS)) or (exit(non-zero) or exit(EXIT_FAILURE) ).

You can simply use if(yourElement)

var a = document.getElementById("elemA");_x000D_
var b = document.getElementById("elemB");_x000D_
_x000D_
if(a)_x000D_
  console.log("elemA exists");_x000D_
else_x000D_
  console.log("elemA does not exist");_x000D_
  _x000D_
if(b)_x000D_
  console.log("elemB exists");_x000D_
else_x000D_
  console.log("elemB does not exist");

<div id="elemA"></div>

If you want to check if a string is empty:

if (str[0] == '\0')
{
    // your code here
}

We can use replace to change the values in 'mpg' to NA that corresponds to cyl==4.

mtcars %>%
     mutate(mpg=replace(mpg, cyl==4, NA)) %>%
     as.data.frame()

I'd not recommend force deleting pods unless container already exited.

1. Verify kubelet logs to see what is causing the issue "journalctl -u kubelet"
2. Verify docker logs: journalctl -u docker.service
3. Check if pod's volume mount points still exist and if anyone holds lock on it.
4. Verify if host is out of memory or disk

Currently I'm using this solution:

$firstDay = new \DateTime('first day of this month');
$lastDay = new \DateTime('last day of this month');

The only issue I came upon is that strange time is being set. I needed correct range for our search interface and I ended up with this:

$firstDay = new \DateTime('first day of this month 00:00:00');
$lastDay = new \DateTime('first day of next month 00:00:00');

If two different views are sharing the same model (for instance, maybe one is for mobile output and one is regular), it could be nice to have the string reside in a single place: as metadata on the ViewModel.

Additionally, if you had an inherited version of the model that necessitated a different display, it could be useful. For instance:

public class BaseViewModel
{
    [Display(Name = "Basic Name")]
    public virtual string Name { get; set; }
}

public class OtherViewModel : BaseViewModel
{
    [Display(Name = "Customized Inherited Name")]
    public override string Name { get; set; }
}

I'll admit that that example is pretty contrived...

Those are the best arguments in favor of using the attribute that I can come up with. My personal opinion is that, for the most part, that sort of thing is best left to the markup.

In general, the cause of the problem could be the following:

You started a new project with the new virtual environment. So probably you install numpy from the terminal, but it is not in your venv. So

• either install it from PyCahrm Interface: Settings -> Project Interpreter -> Add the package

• or activate your venv and -> pip install numPy

You need to use jq 'keys[]'. For example:

echo '{"example1" : 1, "example2" : 2, "example3" : 3}' | jq 'keys[]'

Will output a line separated list:

"example1"
"example2"
"example3"

android:screenOrientation="locked"

in <application> for all app in <activity> for actual activity

As mentioned in other answers, JavaScript regexes have no support for Unicode character classes. However, there is a library that does provide this: Steven Levithan's excellent XRegExp and its Unicode plug-in.

I just add an extra template tag like this:

@register.filter
def in_category(things, category):
    return things.filter(category=category)

Then I can do:

{% for category in categories %}
  {% for thing in things|in_category:category %}
    {{ thing }}
  {% endfor %}
{% endfor %}

You must make sure that the date format is YYYY-MM-DD on your jQuery output. I can see jQuery returns MM-DD-YYYY, which is not the valid MySQL date format and this is why it returns an error.

To convert it to the right one you could do this:

$dateFormated = split('/', $date);
$date = $dateFormated[2].'-'.$dateFormated[0].'-'.$dateFormated[1];

Then you will get formatted date that will be valid MySQL format, which is YYYY-MM-DD, i.e. 2012-08-25

I would also recommend using mysql_real_escape_string as you insert data into database to prevent SQL injections as a quick solution or better use PDO or MySQLi.

Your insert query using mysql_real_escape_string should rather look like this:

$sql = mysql_query( "INSERT INTO user_date VALUE( '', '" .mysql_real_escape_string($name). "', '" .mysql_real_escape_string($date). "'" ) or die ( mysql_error() );

Here is an example returning a value from an internal List object. Should give you the idea.

  public object this[int index]
  {
     get { return ( List[index] ); }
     set { List[index] = value; }
  }

As an addendum to akf's answer you could use instanceof checks instead of String equals() calls:

String cname="com.some.vendor.Impl";
try {
  Class c=this.getClass().getClassLoader().loadClass(cname);
  Object o= c.newInstance();
  if(o instanceof Spam) {
    Spam spam=(Spam) o;
    process(spam);
  }
  else if(o instanceof Ham) {
    Ham ham = (Ham) o;
    process(ham);
  }
  /* etcetera */
}
catch(SecurityException se) {
  System.err.printf("Someone trying to game the system?%nOr a rename is in order because this JVM doesn't feel comfortable with: “%s”", cname);
  se.printStackTrace();
}
catch(LinkageError le) {
  System.err.printf("Seems like a bad class to this JVM: “%s”.", cname);
  le.printStackTrace();
}
catch(RuntimeException re) { 
  // runtime exceptions I might have forgotten. Classloaders are wont to produce those.
  re.printStackTrace();
}
catch(Exception e) { 
  e.printStackTrace();
}

Note the liberal hardcoding of some values. Anyways the main points are:

1. Use instanceof rather than equals(). If anything, it will co-operate better when refactoring.
2. Be sure to catch these runtime errors and security ones too.

It's new in the Bootstrap 3.0.1 release, so make sure you have the latest (10/29)...

If you are using a new, dedicated, user account... It is also worth checking that the password for that account has not expired, as that will also cause this 500.19 permissions issue.

this is how I fix this issue
1.open my project structure

2.click module 3.click plus button 4.click import module,and find the module's pom
5.make sure you select the module you want to import,then next next finish:)

findElement will check the html source and will return true even if the element is not displayed. To check whether an element is displayed or not use -

private boolean verifyElementAbsent(String locator) throws Exception {

        boolean visible = driver.findElement(By.xpath(locator)).isDisplayed();
        boolean result = !visible;
        System.out.println(result);
        return result;
}

run

gradle clean 

then try

gradle build 

it worked for me

When you have classes or methods which don't fit cleanly into the Object-Oriented Paradigm, which do dangerous stuff, which need to be called from other classes and methods under your control, and which you don't want to let anyone else use.

public class DangerousClass {
    public void SafeMethod() { }
    internal void UpdateGlobalStateInSomeBizarreWay() { }
}

setDatabasePath() method was deprecated in API level 19. I advise you to use storage locale like this:

webView.getSettings().setDomStorageEnabled(true);
webView.getSettings().setDatabaseEnabled(true);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
    webView.getSettings().setDatabasePath("/data/data/" + webView.getContext().getPackageName() + "/databases/");
}

NULL is already ignored so you can use NULLIF to turn 0 to NULL. Also you don't need DISTINCT and your WHERE on ActualTime is not sargable.

SELECT AVG(cast(NULLIF(a.SecurityW, 0) AS BIGINT)) AS Average1,
       AVG(cast(NULLIF(a.TransferW, 0) AS BIGINT)) AS Average2,
       AVG(cast(NULLIF(a.StaffW, 0) AS BIGINT))    AS Average3
FROM   Table1 a
WHERE  a.ActualTime >= '20130401'
       AND a.ActualTime < '20130501' 

PS I have no idea what Table2 b is in the original query for as there is no join condition for it so have omitted it from my answer.

In query browser right click on database and select processlist

very basic:

<?php 
$username = 'user';
$password = 'password';
$server = 'localhost'; 
// Opens a connection to a MySQL server
$connection = mysql_connect ($server, $username, $password) or die('try again in some minutes, please');
//if you want to suppress the error message, substitute the connection line for:
//$connection = @mysql_connect($server, $username, $password) or die('try again in some minutes, please');
?>

result:

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'user'@'localhost' (using password: YES) in /home/user/public_html/zdel1.php on line 6 try again in some minutes, please

If iframe is not in the same domain such that you cannot get access to its internals from the parent but you can modify the source code of the iframe then you can modify the page displayed by the iframe to send messages to the parent window, which allows you to share information between the pages. Some sources:

• https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage
• Html5 - Cross Browser Iframe postmessage - child to parent?
• cross site iframe postMessage from child to parent

You should put the input for the last name into the same div where you have the first name.

<div>
    <label for="username">First Name</label>
    <input id="user_first_name" name="user[first_name]" size="30" type="text" />
    <input id="user_last_name" name="user[last_name]" size="30" type="text" />
</div>

Then, in your CSS give your #user_first_name and #user_last_name height and float them both to the left. For example:

#user_first_name{
    max-width:100px; /*max-width for responsiveness*/
    float:left;
}

#user_lastname_name{
    max-width:100px;
    float:left;
}

Use this:

<asp:CustomValidator runat="server" id="vld" ValidateEmptyText="true"/>

To validate an empty field.

You don't need to add 2 validators !

This code may help you:

public class EN implements Serializable {
//... you don't need implement any methods when you implements Serializable
}

Putting data. Create new Activity with extra:

EN enumb = new EN();
Intent intent = new Intent(getActivity(), NewActivity.class);
intent.putExtra("en", enumb); //second param is Serializable
startActivity(intent);

Obtaining data from new activity:

public class NewActivity extends Activity {

    private EN en;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        try {
            super.onCreate(savedInstanceState);

            Bundle extras = getIntent().getExtras();
            if (extras != null) {
                en = (EN)getIntent().getSerializableExtra("en"); //Obtaining data 
            }
//...

First we have to create the simple xml resource file for the textview like as below:

<?xml version="1.0" encoding="utf-8"?>

 <TextView  
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:gravity="left"  
    android:textColor="#FF0000"         
    android:padding="5dip"
    />   

and save it. after set on your adapterlist.

WebpackDevServer localhost from iphone

If you are using an app which is running on node. you can use webpack as a build tool and use their built in devserver

You can use webpackdevserver to start your application from a localhost server and then pass in your localhost address and port of your choice.

webpack-dev-server --host 192.168.0.89 --port 3000

then from your iPhone you can access it using

http://192.168.2.89:3000

Note :: Your laptop and iPhone should be on the same network, and you should use your localhost ip address.

For Mac how to find ip address you can refer Get local IP address in node.js

You should set instead of add to replace existing value at index.

list.add(1, object1)
list.add(2, object3)
list.set(2, object2)

List will contain [object1,object2]

Before you use DecimalFormat you need to use the following import or your code will not work:

import java.text.DecimalFormat;

The code for formatting is:

DecimalFormat precision = new DecimalFormat("0.00"); 
// dblVariable is a number variable and not a String in this case
txtTextField.setText(precision.format(dblVariable));

You should put the button inside a div, and in the div you should be able to use the classes:
text-left, text-center and text-right.

for example:

<div class="row">
   <div class="col text-center">
      <button class="button button-small button-light">Search</button>
   </div>
</div>

And about the "textarea" position:

<div class="list">
<label class="item item-input">
    <span class="input-label">Date</span>
    <input type="text" placeholder="Text Area">
</label>

To add row to JTable, one of the ways is:

1) Create table using DefaultTableModel:

        DefaultTableModel model = new DefaultTableModel();
        model.addColumn("Code");
        model.addColumn("Name");
        model.addColumn("Quantity");
        model.addColumn("Unit Price");
        model.addColumn("Price");
        JTable table = new JTable(model);

2) To add row:

        DefaultTableModel model = (DefaultTableModel) table.getModel();
        model.addRow(new Object[]{"Column 1", "Column 2", "Column 3","Column 4","Column 5"});

You should use Java 8 to solve this, based on the Android documentation you can do this by

clicking File > Project Structure

and change Source Compatibility and Target Compatibility.

and you can also configure it directly in the app-level build.gradle file:

android {
  ...
  // Configure only for each module that uses Java 8
  // language features (either in its source code or
  // through dependencies).
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
}

I was getting similar problem for other reason (url pattern test-response not added in csrf token) I resolved it by allowing my URL pattern in following property in config/local.properties:

csrf.allowed.url.patterns = /[^/]+(/[^?])+(sop-response)$,/[^/]+(/[^?])+(merchant_callback)$,/[^/]+(/[^?])+(hop-response)$

modified to

csrf.allowed.url.patterns = /[^/]+(/[^?])+(sop-response)$,/[^/]+(/[^?])+(merchant_callback)$,/[^/]+(/[^?])+(hop-response)$,/[^/]+(/[^?])+(test-response)$

React Native provides a .measure(...) method which takes a callback and calls it with the offsets and width/height of a component:

myComponent.measure( (fx, fy, width, height, px, py) => {

    console.log('Component width is: ' + width)
    console.log('Component height is: ' + height)
    console.log('X offset to frame: ' + fx)
    console.log('Y offset to frame: ' + fy)
    console.log('X offset to page: ' + px)
    console.log('Y offset to page: ' + py)
})

Example...

The following calculates the layout of a custom component after it is rendered:

class MyComponent extends React.Component {
    render() {
        return <View ref={view => { this.myComponent = view; }} />
    }
    componentDidMount() {
        // Print component dimensions to console
        this.myComponent.measure( (fx, fy, width, height, px, py) => {
            console.log('Component width is: ' + width)
            console.log('Component height is: ' + height)
            console.log('X offset to frame: ' + fx)
            console.log('Y offset to frame: ' + fy)
            console.log('X offset to page: ' + px)
            console.log('Y offset to page: ' + py)
        })        
    }
}

Bug notes

• Note that sometimes the component does not finish rendering before componentDidMount() is called. If you are getting zeros as a result from measure(...), then wrapping it in a setTimeout should solve the problem, i.e.:

  setTimeout( myComponent.measure(...), 0 )
  

Actually your $product has no data because the Eloquent model returns NULL. It's probably because you have used whereOwnerAndStatus which seems wrong and if there were data in $product then it would not work in your first example because get() returns a collection of multiple models but that is not the case. The second example throws error because foreach didn't get any data. So I think it should be something like this:

$owner = Input::get('owner');
$count = Input::get('count');
$products = Product::whereOwner($owner, 0)->take($count)->get();

Further you may also make sure if $products has data:

if($product) {
    return View:make('viewname')->with('products', $products);
}

Then in the view:

foreach ($products as $product) {
    // If Product has sku (collection object, probably related models)
    foreach ($product->sku as $sku) {
        // Code Here        
    }
}

Of course you can sample each row:

sapply (1:4, function (row) df1[row,]<<-sample(df1[row,]))

will shuffle the rows itself, so the number of 1's in each row doesn't change. Small changes and it also works great with columns, but this is a exercise for the reader :-P

Any ranking of various data structures will be at least partially tied to problem context. It would help to learn how to analyze time and space performance of algorithms. Typically, "big O notation" is used, e.g. binary search is in O(log n) time, which means that the time to search for an element is the log (in base 2, implicitly) of the number of elements. Intuitively, since every step discards half of the remaining data as irrelevant, doubling the number of elements will increases the time by 1 step. (Binary search scales rather well.) Space performance concerns how the amount of memory grows for larger data sets. Also, note that big-O notation ignores constant factors - for smaller data sets, an O(n^2) algorithm may still be faster than an O(n * log n) algorithm that has a higher constant factor. Complex algorithms often have more work to do on startup.

Besides time and space, other characteristics include whether a data structure is sorted (trees and skiplists are sorted, hash tables are not), persistence (binary trees can reuse pointers from older versions, while hash tables are modified in place), etc.

While you'll need to learn the behavior of several data structures to be able to compare them, one way to develop a sense for why they differ in performance is to closely study a few. I'd suggest comparing singly-linked lists, binary search trees, and skip lists, all of which are relatively simple, but have very different characteristics. Think about how much work it takes to find a value, add a new value, find all values in order, etc.

There are various texts on analyzing algorithms / data structure performance that people recommend, but what really made them make sense to me was learning OCaml. Dealing with complex data structures is ML's strong suit, and their behavior is much clearer when you can avoid pointers and memory management as in C. (Learning OCaml just to understand data structures is almost certainly the long way around, though. :) )

You can make an extension of UIImageView.

Swift 2.0

import Foundation
import UIKit

extension UIImageView
{
    func makeBlurImage(targetImageView:UIImageView?)
    {
        let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.Dark)
        let blurEffectView = UIVisualEffectView(effect: blurEffect)
        blurEffectView.frame = targetImageView!.bounds

        blurEffectView.autoresizingMask = [.FlexibleWidth, .FlexibleHeight] // for supporting device rotation
        targetImageView?.addSubview(blurEffectView)
    }
}

Usage:

override func viewDidLoad()
{
    super.viewDidLoad()

    let sampleImageView = UIImageView(frame: CGRectMake(0, 200, 300, 325))
    let sampleImage:UIImage = UIImage(named: "ic_120x120")!
    sampleImageView.image =  sampleImage

    //Convert To Blur Image Here
    sampleImageView.makeBlurImage(sampleImageView)

    self.view.addSubview(sampleImageView)
}

Swift 3 Extension

import Foundation
import UIKit

extension UIImageView
{
    func addBlurEffect()
    {
        let blurEffect = UIBlurEffect(style: UIBlurEffectStyle.light)
        let blurEffectView = UIVisualEffectView(effect: blurEffect)
        blurEffectView.frame = self.bounds

        blurEffectView.autoresizingMask = [.flexibleWidth, .flexibleHeight] // for supporting device rotation
        self.addSubview(blurEffectView)
    }
}

Usage:

yourImageView.addBlurEffect()

Addendum:

extension UIView {
  
  /// Remove UIBlurEffect from UIView
  func removeBlurEffect() {
    let blurredEffectViews = self.subviews.filter{$0 is UIVisualEffectView}
    blurredEffectViews.forEach{ blurView in
      blurView.removeFromSuperview()
    }
  }

Swift 5.0:

import UIKit


extension UIImageView {
    func applyBlurEffect() {
        let blurEffect = UIBlurEffect(style: .light)
        let blurEffectView = UIVisualEffectView(effect: blurEffect)
        blurEffectView.frame = bounds
        blurEffectView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        addSubview(blurEffectView)
    }
}

Adaptive thresholding is important if the lighting is uneven across the image. My preprocessing using GraphicsMagic is mentioned in this post: https://groups.google.com/forum/#!topic/tesseract-ocr/jONGSChLRv4

GraphicsMagic also has the -lat feature for Linear time Adaptive Threshold which I will try soon.

Another method of thresholding using OpenCV is described here: http://docs.opencv.org/trunk/doc/py_tutorials/py_imgproc/py_thresholding/py_thresholding.html

A For() loop is very useful. You can add your array's value to another variable like this:

<?php
    $dizi=array('mother','father','child'); //This is array

    $sayi=count($dizi);
    for ($i=0; $i<$sayi; $i++) {
        $dizin.=("'$dizi[$i]',"); //Now it is string...
    }
         echo substr($dizin,0,-1); //Write it like string :D
?>

In this code we added $dizi's values and comma to $dizin:

$dizin.=("'$dizi[$i]',");

Now

$dizin = 'mother', 'father', 'child',

It's a string, but it has an extra comma :)

And then we deleted the last comma, substr($dizin, 0, -1);

Output:

'mother','father','child'

the plus works just fine, i personally prefer using the concat function.

var s = string.Concat(string 1, string 2, string, 3, etc)

You need to use WITH ROLLBACK IMMEDIATE to boot other conections out with no regards to what or who is is already using it.

Or use WITH NO_WAIT to not hang and not kill existing connections. See http://www.blackwasp.co.uk/SQLOffline.aspx for details

If you deployed the package to the "Integration Services Catalog" on SSMS you can retrieve the package using Visual studio.

First thing to do is run this:

SHOW GRANTS;

You will quickly see you were assigned the anonymous user to authenticate into mysql.

Instead of logging into mysql with

mysql

login like this:

mysql -uroot

By default, root@localhost has all rights and no password.

If you cannot login as root without a password, do the following:

Step 01) Add the two options in the mysqld section of my.ini:

[mysqld]
skip-grant-tables
skip-networking

Step 02) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 03) Connect to mysql

mysql

Step 04) Create a password from root@localhost

UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit

Step 05) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 06) Login as root with password

mysql -u root -p

You should be good from there.

CAVEAT: Please remove anonymous users !!!

First of all, from __future__ import print_function needs to be the first line of code in your script (aside from some exceptions mentioned below). Second of all, as other answers have said, you have to use print as a function now. That's the whole point of from __future__ import print_function; to bring the print function from Python 3 into Python 2.6+.

from __future__ import print_function

import sys, os, time

for x in range(0,10):
    print(x, sep=' ', end='')  # No need for sep here, but okay :)
    time.sleep(1)

__future__ statements need to be near the top of the file because they change fundamental things about the language, and so the compiler needs to know about them from the beginning. From the documentation:

A future statement is recognized and treated specially at compile time: Changes to the semantics of core constructs are often implemented by generating different code. It may even be the case that a new feature introduces new incompatible syntax (such as a new reserved word), in which case the compiler may need to parse the module differently. Such decisions cannot be pushed off until runtime.

The documentation also mentions that the only things that can precede a __future__ statement are the module docstring, comments, blank lines, and other future statements.

In an activity you can call recreate() to "recreate" the activity (API 11+)

This command will redirect the output to a text file of your choice:

$hive -e "select * from table where id > 10" > ~/sample_output.txt

There is also someone who managed to modify CR for VS.NET 2010 to install on 2012, using MS ORCA in this thread: http://scn.sap.com/thread/3235515 . I couldn't get it to work myself, though.

You must add this line in your EditText in xml:

android:maxLines="1"

box-shadow: -15px 0px 17px -7px rgba(0,0,0,0.75);

The first px value is the "Horizontal Length" set to -15px to position the shadow towards the left, the next px value is set to 0 so the shadow top and bottom is centred to minimise the top and bottom shadow.

The third value(17px) is known as the blur radius. The higher the number, the more blurred the shadow will be. And then last px value -7px is The spread radius, a positive value increases the size of the shadow, a negative value decreases the size of the shadow, at -7px it keeps the shadow from appearing above and below the item.

people.OrderBy(person => person.lastname).ToList();

change the MaxClients directive. it is now on 256.

Integers are autounboxed, so you can just do

if (count > 0) {
    .... 
}

you can try this in the stylesheet:

@page{size:auto; margin-bottom:5mm;}

But this also removes the page number

Try the following statement:

select  distinct A.[Tag],
     count(A.[Tag]) as TAG_COUNT,
     (SELECT count(*) FROM [TagTbl] AS B WHERE A.[Tag]=B.[Tag] AND B.[ID]>0)
     from [TagTbl] AS A GROUP BY A.[Tag]

The first field will be the tag the second will be the whole count the third will be the positive ones count.

• In terms of speed: #1 and #4, but not by much in most instances.

  You could write a benchmark to confirm, but I suspect you'll find #1 and #4 to be slightly faster because the iteration work is done in C instead of Perl, and no needless copying of the array elements occurs. ($_ is aliased to the element in #1, but #2 and #3 actually copy the scalars from the array.)

  #5 might be similar.

• In terms memory usage: They're all the same except for #5.

  for (@a) is special-cased to avoid flattening the array. The loop iterates over the indexes of the array.

• In terms of readability: #1.

• In terms of flexibility: #1/#4 and #5.

  #2 does not support elements that are false. #2 and #3 are destructive.

for logical && both the parameters must be true , then it ll be entered in if {} clock otherwise it ll execute else {}. for logical || one of parameter or condition is true is sufficient to execute if {}.

if( (A) && (B) ){
     //if A and B both are true
}else{
}
if( (A) ||(B) ){
     //if A or B is true 
}else{
}

If you check out the help of the unittest module it tells you about several combinations that allow you to run test case classes from a module and test methods from a test case class.

python3 -m unittest -h

[...]

Examples:
  python3 -m unittest test_module               - run tests from test_module
  python3 -m unittest module.TestClass          - run tests from module.TestClass
  python3 -m unittest module.Class.test_method  - run specified test method
```lang-none

It does not require you to define a `unittest.main()` as the default behaviour of your module.

try some thing like blow:

SString otherParametersUrServiceNeed =  "Company=acompany&Lng=test&MainPeriod=test&UserID=123&CourseDate=8:10:10";
String request = "http://android.schoolportal.gr/Service.svc/SaveValues";

URL url = new URL(request); 
HttpURLConnection connection = (HttpURLConnection) url.openConnection();   
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setInstanceFollowRedirects(false); 
connection.setRequestMethod("POST"); 
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
connection.setRequestProperty("charset", "utf-8");
connection.setRequestProperty("Content-Length", "" + Integer.toString(otherParametersUrServiceNeed.getBytes().length));
connection.setUseCaches (false);

DataOutputStream wr = new DataOutputStream(connection.getOutputStream ());
wr.writeBytes(otherParametersUrServiceNeed);

   JSONObject jsonParam = new JSONObject();
jsonParam.put("ID", "25");
jsonParam.put("description", "Real");
jsonParam.put("enable", "true");

wr.writeBytes(jsonParam.toString());

wr.flush();
wr.close();

Various browsers have various limits for maximum connections per host name; you can find the exact numbers at http://www.browserscope.org/?category=network and here is an interesting article about connection limitations from web performance expert Steve Souders http://www.stevesouders.com/blog/2008/03/20/roundup-on-parallel-connections/

A semaphore is an object containing a natural number (i.e. a integer greater or equal to zero) on which two modifying operations are defined. One operation, V, adds 1 to the natural. The other operation, P, decreases the natural number by 1. Both activities are atomic (i.e. no other operation can be executed at the same time as a V or a P).

Because the natural number 0 cannot be decreased, calling P on a semaphore containing a 0 will block the execution of the calling process(/thread) until some moment at which the number is no longer 0 and P can be successfully (and atomically) executed.

As mentioned in other answers, semaphores can be used to restrict access to a certain resource to a maximum (but variable) number of processes.

This Works Flawless....

Best way to install Go on Ubuntu is to download required version from here. Here you could have all stable and releases, along with archived versions.

after downloading you selected version you can follow further steps, i will suggest you to download tar.gz format for ubuntu machine:

1. first of all fully remove the older version from your local by doing this

sudo rm -rf /usr/local/go /usr/local/gocache

this will remove all the local go code base but wait something more we have to do to remove fully from local, i was missing this step and it took so much time until I understood what i am missing so here is the purge stuff to remove from list

sudo apt-get purge golang

or

sudo apt remove golang-go

2. Now install / extract your downloaded version of go inside /usr/local/go, by hitting terminal with this

tar -C /usr/local -xzf go1.10.8.linux-amd64.tar.gz

3. after doing all above stuff , don't forget or check to GOROOT variable value you can check the value by go env if not set then export PATH=$PATH:/usr/local/go
4. Better to test a small go program to make sure. write this inside /home/yourusername/go/test.php if you haven't changed set GOPATH value:

package main

import "fmt"

func main() {
    fmt.Println("hello world")
}

5. run this by go run test.go

i hope it works for you!!

If it has to be "nested", this would be one way, to get your job done:

SELECT o.name AS country, o.headofstate 
FROM   country o
WHERE  o.headofstate like 'A%'
AND   (
    SELECT i.population
    FROM   city i
    WHERE  i.id = o.capital
    ) > 100000

A JOIN would be more efficient than a correlated subquery, though. Can it be, that who ever gave you that task is not up to speed himself?

We have overcome some limitations of the responsiveness of the Facebook plugin by using it as an IFRAME, but bootstrapping at render time with some JavaScript that dynamically sizes the frame (and width/height parameters in the SRC URL) to fill the container element.

If the container is greater than 500px, to avoid having an obvious gutter on the right hand side, we simply add a scale transform with some simple math.

The IFRAME onload event fires when SRC is initially empty (when we bootstrap it) and then again after it finishes loading when we set the SRC, but we simply short-out if SRC attribute already exists.

In our usage, we don't change the width of the Facebook feed for desktop usage, and for handheld/tablet viewports, those widths are fixed by nature (yes, we trap orientation change) but if you want yours to continually adjust if the browser window dimensions change, you could just re-fire the code as an exercise for yourself.

This is tested in with Chrome and Safari, on desktop and iOS/Android:

<script>
    function setupFBframe(frame) {

        if(frame.src) return; // already set up

        // get parent container dimensions to use in src attrib
        var container = frame.parentNode;

        var containerWidth = container.offsetWidth;
        var containerHeight = container.offsetHeight;

        var src = 'https://www.facebook.com/plugins/page.php' +
                '?href=https%3A%2F%2Fwww.facebook.com%2FYourFacebookAddress%2F' +
                '&tabs=timeline' +
                '&width=' + containerWidth +
                '&height=' + containerHeight +
                '&small_header=true' +
                '&adapt_container_width=false' + /* doesn't seem to matter */
                '&hide_cover=true' +
                '&hide_cta=true' +
                '&show_facepile=false' +
                '&appId';

        frame.width = containerWidth;
        frame.height = containerHeight;
        frame.src = src;

        // scale up if container > 500px wide
        if(containerWidth) > 500) {
            var scale = (containerWidth / 500 );
            frame.style.transform = 'scale(' + scale + ')';
        }
    }
</script>
<style>
    #facebook_iframe {
        transform-origin: 0 0;
        -webkit-transform-origin: 0px 0px;
        -moz-transform-origin: 0px 0px;
    }
</style>
<iframe frameborder="0" height="0" width="0" onload="var _this = this; window.setTimeout(function(){ setupFBframe(_this); },500 /* let dom settle before eval parent dimensions */ );"></iframe>

EDIT: Forgot about transform-origin, removed need for adjusting left/top to accommodate scale. Thanks Io Ctaptceb

Here is another one liner using lambdas (create column with constant value = 10)

df['newCol'] = df.apply(lambda x: 10, axis=1)

before

df

1   1.764052    0.400157    0.978738
2   2.240893    1.867558    -0.977278
3   0.950088    -0.151357   -0.103219

after

df
        A           B           C           newCol
    1   1.764052    0.400157    0.978738    10
    2   2.240893    1.867558    -0.977278   10
    3   0.950088    -0.151357   -0.103219   10

hope it's worked for you:

File yourFile = new File(Environment.getExternalStorageDirectory(), "textarabics.txt");

This will give u sdcard path:

File path = Environment.getExternalStorageDirectory();

Try this:

String pathName = "/mnt/";

or try this:

String pathName = "/storage/";

Evidently, sometimes, the display properties of parent of the element containing the matter that shouldn't overflow should also be set to overflow:hidden as well, e.g.:

<div style="overflow: hidden">
  <div style="overflow: hidden">some text that should not overflow<div>
</div>

Why? I have no idea but it worked for me. See https://medium.com/@crrollyson/overflow-hidden-not-working-check-the-child-element-c33ac0c4f565 (ignore the sniping at stackoverflow!)

With jQuery:

$('form').submit(function () {
    // Validate here

    if (pass)
        return true;
    else
        return false;
});

my_hash = {:a => 5}
my_hash[:key] = "value"

I disagree with the document.write technique (see suggestion of Vahan Margaryan). I like document.getElementsByTagName('head')[0].appendChild(...) (see suggestion of Matt Ball), but there is one important issue: the script execution order.

Recently, I have spent a lot of time reproducing one similar issue, and even the well-known jQuery plugin uses the same technique (see src here) to load the files, but others have also reported the issue. Imagine you have JavaScript library which consists of many scripts, and one loader.js loads all the parts. Some parts are dependent on one another. Imagine you include another main.js script per <script> which uses the objects from loader.js immediately after the loader.js. The issue was that sometimes main.js is executed before all the scripts are loaded by loader.js. The usage of $(document).ready(function () {/*code here*/}); inside of main.js script does not help. The usage of cascading onload event handler in the loader.js will make the script loading sequential instead of parallel, and will make it difficult to use main.js script, which should just be an include somewhere after loader.js.

By reproducing the issue in my environment, I can see that **the order of execution of the scripts in Internet Explorer 8 can differ in the inclusion of the JavaScript*. It is a very difficult issue if you need include scripts that are dependent on one another. The issue is described in Loading Javascript files in parallel, and the suggested workaround is to use document.writeln:

document.writeln("<script type='text/javascript' src='Script1.js'></script>");
document.writeln("<script type='text/javascript' src='Script2.js'></script>");

So in the case of "the scripts are downloaded in parallel but executed in the order they're written to the page", after changing from document.getElementsByTagName('head')[0].appendChild(...) technique to document.writeln, I had not seen the issue anymore.

So I recommend that you use document.writeln.

UPDATED: If somebody is interested, they can try to load (and reload) the page in Internet Explorer (the page uses the document.getElementsByTagName('head')[0].appendChild(...) technique), and then compare with the fixed version used document.writeln. (The code of the page is relatively dirty and is not from me, but it can be used to reproduce the issue).

Summary (@Freek Wiekmeijer, @gtalarico) other's answer:

Logic of Login

• Many resource(pages, api) need authentication, then can access, otherwise 405 Not Allowed
• Common authentication=grant access method are:
  • cookie
  • auth header
    • Basic xxx
    • Authorization xxx

How use cookie in requests to auth

1. first get/generate cookie
2. send cookie for following request

• manual set cookie in headers
• auto process cookie by requests's
  • session to auto manage cookies
  • response.cookies to manually set cookies

use requests's session auto manage cookies

curSession = requests.Session() 
# all cookies received will be stored in the session object

payload={'username': "yourName",'password': "yourPassword"}
curSession.post(firstUrl, data=payload)
# internally return your expected cookies, can use for following auth

# internally use previously generated cookies, can access the resources
curSession.get(secondUrl)

curSession.get(thirdUrl)

manually control requests's response.cookies

payload={'username': "yourName",'password': "yourPassword"}
resp1 = requests.post(firstUrl, data=payload)

# manually pass previously returned cookies into following request

On Windows 7 with Firefox 10, the cert8.db file is stored at %userprofile%\AppData\Roaming\Mozilla\Firefox\Profiles\########.default\cert8.db. If you are an administrator, you can probably write a simple WMI application to copy the file to the User's respective folder.

Also, a solution that worked for me from http://www.appdeploy.com/messageboards/tm.asp?m=52532&mpage=1&key=&#52532

1. Copied CERTUTIL.EXE from the NSS zip file ( http://www.mozilla.org/projects/security/pki/nss/tools/ ) to C:\Temp\CertImport (I also placed the certificates I want to import there)

2. Copied all the dll's from the NSS zip file to C\:Windows\System32

3. Created a BAT file in %Appdata%\mozilla\firefox\profiles with this script...

   Set FFProfdir=%Appdata%\mozilla\firefox\profiles 
   Set CERTDIR=C:\Temp\CertImport 
   DIR /A:D /B > "%Temp%\FFProfile.txt" 
   FOR /F "tokens=*" %%i in (%Temp%\FFProfile.txt) do ( 
   CD /d "%FFProfDir%\%%i" 
   COPY cert8.db cert8.db.orig /y 
   For %%x in ("%CertDir%\Cert1.crt") do "%Certdir%\certutil.exe" -A -n "Cert1" -i "%%x" -t "TCu,TCu,TCu" -d . 
   For %%x in ("%CertDir%\Cert2.crt") do "%Certdir%\certutil.exe" -A -n "Cert2" -i "%%x" -t "TCu,TCu,TCu" -d . 
   ) 
   DEL /f /q "%Temp%\FFProfile.txt" 
   

4. Executed the BAT file with good results.

There's a plug-in for this if you don't want to write a bare-bones implementation yourself. It's called "scrollTo" (link). It allows you to perform programmed scrolling to certain points, or use values like -= 10px for continuous scrolling.

option-1:

edit \My Documents\IISExpress\config\applicationhost.config file and enable windowsAuthentication, i.e:

<system.webServer>
...
  <security>
...
    <authentication>
      <windowsAuthentication enabled="true" />
    </authentication>
...
  </security>
...
</system.webServer>

option-2:

Unlock windowsAuthentication section in \My Documents\IISExpress\config\applicationhost.config as follows

<add name="WindowsAuthenticationModule" lockItem="false" />

Alter override settings for the required authentication types to 'Allow'

<sectionGroup name="security">
    ...
    <sectionGroup name="system.webServer">
        ...
        <sectionGroup name="authentication">
            <section name="anonymousAuthentication" overrideModeDefault="Allow" />
            ...
            <section name="windowsAuthentication" overrideModeDefault="Allow" />
    </sectionGroup>
</sectionGroup>

Add following in the application's web.config

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
      <security>
        <authentication>
          <windowsAuthentication enabled="true" />
        </authentication>
      </security>
    </system.webServer>
</configuration>

Below link may help: http://learn.iis.net/page.aspx/376/delegating-configuration-to-webconfig-files/

After installing VS 2010 SP1 applying option 1 + 2 may be required to get windows authentication working. In addition, you may need to set anonymous authentication to false in IIS Express applicationhost.config:

<authentication>

            <anonymousAuthentication enabled="false" userName="" />

for VS2015, the IIS Express applicationhost config file may be located here:

$(solutionDir)\.vs\config\applicationhost.config

and the <UseGlobalApplicationHostFile> option in the project file selects the default or solution-specific config file.

I agree with the existing answers that the second form is better because it does not have any side effects and is easier to parallelise (just use a parallel stream).

Performance wise, it appears they are equivalent until you start using parallel streams. In that case, map will perform really much better. See below the micro benchmark results:

Benchmark                         Mode  Samples    Score   Error  Units
SO28319064.forEach                avgt      100  187.310 ± 1.768  ms/op
SO28319064.map                    avgt      100  189.180 ± 1.692  ms/op
SO28319064.mapWithParallelStream  avgt      100   55,577 ± 0,782  ms/op

You can't boost the first example in the same manner because forEach is a terminal method - it returns void - so you are forced to use a stateful lambda. But that is really a bad idea if you are using parallel streams.

Finally note that your second snippet can be written in a sligthly more concise way with method references and static imports:

myFinalList = myListToParse.stream()
    .filter(Objects::nonNull)
    .map(this::doSomething)
    .collect(toList()); 

Have you noticed that in the code you posted, condition2 is never set to False? This way, your loop body is never executed.

Also, note that in Python, not condition is preferred to condition == False; likewise, condition is preferred to condition == True.

Thanks for the help. This is what I ended up doing in order to make it work.

CREATE VIEW V AS
    SELECT *
    FROM ((POP NATURAL FULL OUTER JOIN FOOD)
    NATURAL FULL OUTER JOIN INCOME);

swift 5, swift 4.2 can use the code in the below.

// disable
self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
// enable
self.navigationController?.interactivePopGestureRecognizer?.isEnabled = true

Since the value of $var is the empty string, this:

if [ $var == $var1 ]; then

expands to this:

if [ == abcd ]; then

which is a syntax error.

You need to quote the arguments:

if [ "$var" == "$var1" ]; then

You can also use = rather than ==; that's the original syntax, and it's a bit more portable.

If you're using bash, you can use the [[ syntax, which doesn't require the quotes:

if [[ $var = $var1 ]]; then

Even then, it doesn't hurt to quote the variable reference, and adding quotes:

if [[ "$var" = "$var1" ]]; then

might save a future reader a moment trying to remember whether [[ ... ]] requires them.

The simplest way to do this in plain bash is to use process substitution instead of a pipeline. There are several differences, but they probably don't matter very much for your use case:

• When running a pipeline, bash waits until all processes complete.
• Sending Ctrl-C to bash makes it kill all the processes of a pipeline, not just the main one.
• The pipefail option and the PIPESTATUS variable are irrelevant to process substitution.
• Possibly more

With process substitution, bash just starts the process and forgets about it, it's not even visible in jobs.

Mentioned differences aside, consumer < <(producer) and producer | consumer are essentially equivalent.

If you want to flip which one is the "main" process, you just flip the commands and the direction of the substitution to producer > >(consumer). In your case:

command > >(tee out.txt)

Example:

$ { echo "hello world"; false; } > >(tee out.txt)
hello world
$ echo $?
1
$ cat out.txt
hello world

$ echo "hello world" > >(tee out.txt)
hello world
$ echo $?
0
$ cat out.txt
hello world

As I said, there are differences from the pipe expression. The process may never stop running, unless it is sensitive to the pipe closing. In particular, it may keep writing things to your stdout, which may be confusing.

As your output results a double you should cast either completed variable or total variable or both to double while dividing.

So, the correct implmentation will be:

System.out.println((double)completed/total);

If you are using the prawn gem for Ruby on Rails to generate your PDF, you can use the following additional gem to active the print dialog:

Here is a simple way to understand the concept: The basic idea is, if you want a collection that you can use "foreach" on, but gathering the items into the collection is expensive for some reason (like querying them out of a database), AND you will often not need the entire collection, then you create a function that builds the collection one item at a time and yields it back to the consumer (who can then terminate the collection effort early).

Think of it this way: You go to the meat counter and want to buy a pound of sliced ham. The butcher takes a 10-pound ham to the back, puts it on the slicer machine, slices the whole thing, then brings the pile of slices back to you and measures out a pound of it. (OLD way). With yield, the butcher brings the slicer machine to the counter, and starts slicing and "yielding" each slice onto the scale until it measures 1-pound, then wraps it for you and you're done. The Old Way may be better for the butcher (lets him organize his machinery the way he likes), but the New Way is clearly more efficient in most cases for the consumer.

You only clone once, so if you already have a clone of the remote repository, pulling from it won't download everything again. Just indicate what branch you want to pull, or fetch the changes and checkout the commit you want.

Fetching from a new repository is very cheap in bandwidth, as it will only download the changes you don't have. Think in terms of Git making the right thing, with minimum load.

Git stores everything in .git folder. A commit can't be fetched and stored in isolation, it needs all its ancestors. They are interrelated.

To reduce download size you can however ask git to fetch only objects related to a specific branch or commit:

git fetch origin refs/heads/branch:refs/remotes/origin/branch

This will download only commits contained in remote branch branch (and only the ones that you miss), and store it in origin/branch. You can then merge or checkout.

You can also specify only a SHA1 commit:

git fetch origin 96de5297df870:refs/remotes/origin/foo-commit

This will download only the commit of the specified SHA-1 96de5297df870 (and its ancestors that you miss), and store it as (non-existing) remote branch origin/foo-commit.

If you are on Windows and have Visual Studio installed you might have something in your PATH that is pointing to an old version of TypeScript. I found that removing the folder "C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.0\" from my PATH (or deleting/renaming this folder) will allow the more recent npm globally installed TypeScript version of tsc to work.

Solution for me was to set the "form" attribute of button

<form id="form_id_name"><button name="btnSubmit" form="form_id_name" /></form>

or is js:

YOURFORMOBJ.getElementsByTagName("button")[0].setAttribute("form", "form_id_name");
YOURFORMOBJ.submit();

You could use an input mask on the text box, too. If you set the mask to ##/##/#### it will always be formatted as you type and you don't need to do any coding other than checking to see if what was entered was a true date.

Which just a few easy lines

txtUserName.SetFocus
If IsDate(txtUserName.text) Then
    Debug.Print Format(CDate(txtUserName.text), "MM/DD/YYYY")
Else
    Debug.Print "Not a real date"
End If

import io, pygame, zipfile
archive = zipfile.ZipFile('images.zip', 'r')

# read bytes from archive
img_data = archive.read('img_01.png')

# create a pygame-compatible file-like object from the bytes
bytes_io = io.BytesIO(img_data)

img = pygame.image.load(bytes_io)

I was trying to figure this out for myself just now and thought this might be useful for anyone who comes across this question in the future.

It looks to me like the background images aren't actually background images...the site has the background images and the quotes in sibling divs with the children of the div containing the images having been assigned position: fixed; The quotes div is also given a transparent background.

wrapper div{
   image wrapper div{
       div for individual image{ <--- Fixed position
          image <--- relative position
       }
   }
   quote wrapper div{
       div for individual quote{
          quote
       }
   }
 }

If you are using python3 and looking for the translate solution - the function was changed and now takes 1 parameter instead of 2.

That parameter is a table (can be dictionary) where each key is the Unicode ordinal (int) of the character to find and the value is the replacement (can be either a Unicode ordinal or a string to map the key to).

Here is a usage example:

>>> list = [',', '!', '.', ';']
>>> s = "This is, my! str,ing."
>>> s.translate({ord(x): '' for x in list})
'This is my string'

Do this

    <% for(int i = 0; i < allFestivals.size(); i+=1) { %>
        <tr>      
            <td><%=allFestivals.get(i).getFestivalName()%></td>
        </tr>
    <% } %>

I had tried most of the answers here but didn't manage to resolve the issue (on Windows 10).

What resolved the problem was simply to upgrade version from git version 2.8.1.windows.1 to the latest version git version 2.10.1.windows.1

If you really need it inline, for example because you are loading some user-defined colors dynamically, you can always add a <style> element right before your content.

<style>#project-slide-1:before { color: #ff0000; }</style>
<div id="project-slide-1" class="project-slide"> ... </div>

Example use case with PHP and some (wordpress inspired) dummy functions:

<style>#project-slide-<?php the_ID() ?>:before { color: <?php the_field('color') ?>; }</style>
<div id="project-slide-<?php the_ID() ?>" class="project-slide"> ... </div>

Since HTML 5.2 it is valid to place style elements inside the body, although it is still recommend to place style elements in the head.

The Eclipse UI is a little bit confusing.

The Import -> "Existing projects into workspace" actually means import "Existing Eclipse projects into workspace". That's why you can't click on finish: the import option looks for a .project file (the file used by Eclipse to store the project options) in the directory that you have chosen.

To import existing source code that doesn't have an Eclipse project file you have the following options (I suppose that you want to create a Java project):

1. New project inside the workspace dir: Create a new empty Java project into the workspace (File->New->Java Project). Then right click on the source folder and choose Import...->General->File system then choose your files, and it will make a copy of your files.

   Tip: you can drag&drop your files from the Finder into the src folder.

2. Create an eclipse project in your existing dir: Create a new Java project, but in the "New Java Project" window:

   • Un check the Use default location option, and choose the directory where is your non-Eclipse project.
   • Click Next and configure the sub-directories of your non-Eclipse project where the source files are located. And you are done :)

Considering larsks' answer, you can get it working with a single command with "--force":

You build the object before encoding it to a JSON string:

import json

data = {}
data['key'] = 'value'
json_data = json.dumps(data)

JSON is a serialization format, textual data representing a structure. It is not, itself, that structure.

yes, but only if main is declared public

Additionally for what was said, if you want integer powers of two, then 1 << x (or 1L << x) is a faster way to calculate 2^x than Math.pow(2,x) or a multiplication loop, and is guaranteed to give you an int (or long) result.

It only uses the lowest 5 (or 6) bits of x (i.e. x & 31 (or x & 63)), though, shifting between 0 and 31 (or 63) bits.

TL;DR

useEffect(yourCallback, []) - will trigger the callback only after the first render.

Detailed explanation

useEffect runs by default after every render of the component (thus causing an effect).

When placing useEffect in your component you tell React you want to run the callback as an effect. React will run the effect after rendering and after performing the DOM updates.

If you pass only a callback - the callback will run after each render.

If passing a second argument (array), React will run the callback after the first render and every time one of the elements in the array is changed. for example when placing useEffect(() => console.log('hello'), [someVar, someOtherVar]) - the callback will run after the first render and after any render that one of someVar or someOtherVar are changed.

By passing the second argument an empty array, React will compare after each render the array and will see nothing was changed, thus calling the callback only after the first render.

I found that The Boolean Expression Reducer is much easier to use than Logic Friday. Plus it doesn't require installation and is multi-platform (Java).

Also in Logic Friday the expression A | B just returns 3 entries in truth table; I expected 4.

Firebug as Firefox (FF) extension is currently (as per 01/2017) the only way to debug direct javascript responses from AJAX calls. Unfortunately, it's development is discontinued. And since Firefox 50, the Firebug also cannot be installed anymore due to compatability issues :-( They kind of emulated FF developer tools UI to recall Firebug UI in some way.

Unfortunatelly, FF native developer tools are not able to debug javascript returned directly by AJAX calls. Same applies to Chrome devel. tools.

I must have disabled upgrades of FF due to this issue, since I badly need to debug JS from XHR calls on current project. So not good news here - let's hope the feature to debug direct JS responses will be incorporated into FF/Chrome developer tools soon.

You don't need to go to 64-bit to see something like this. Consider int32_t on common 32-bit platforms. It might be typedef'ed as int or as a long, but obviously only one of the two at a time. int and long are of course distinct types.

It's not hard to see that there is no workaround which makes int == int32_t == long on 32-bit systems. For the same reason, there's no way to make long == int64_t == long long on 64-bit systems.

If you could, the possible consequences would be rather painful for code that overloaded foo(int), foo(long) and foo(long long) - suddenly they'd have two definitions for the same overload?!

The correct solution is that your template code usually should not be relying on a precise type, but on the properties of that type. The whole same_type logic could still be OK for specific cases:

long foo(long x);
std::tr1::disable_if(same_type(int64_t, long), int64_t)::type foo(int64_t);

I.e., the overload foo(int64_t) is not defined when it's exactly the same as foo(long).

[edit] With C++11, we now have a standard way to write this:

long foo(long x);
std::enable_if<!std::is_same<int64_t, long>::value, int64_t>::type foo(int64_t);

[edit] Or C++20

long foo(long x);
int64_t foo(int64_t) requires (!std::is_same_v<int64_t, long>);

With text-wrap, browser support is relatively weak (as you might expect from from a draft spec).

You are better off taking steps to ensure the data doesn't have long strings of non-white-space.

I have had the same problem as noted above. I could not get Eclipse to install because of Java incompatibilities. The sequence I followed goes like this:

1. Upgraded to MAC OS Sierra
2. Downloaded the Eclipse installer but was prompted that I needed to instal a legacy Java.
3. Installed Java 1.6
4. Was unable to install Eclipse and was prompted that I needed Java 1.7 or greater. Downloaded and installed Java 1.8
5. Ran the terminal code 'java -version' // this will check your jre version. This showed returned Java 1.6 despite the fact that I had upgraded to 1.8. The Java version listed in the Java control panel said 1.8
6. Tried multiple downloads of eclipse and Java and multiple restarts always with the same result.
7. Visited the Oracle web page noted above: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html I could not find the above reference to 8u73 and 8u74 but I did find and option to download 1.8.0_12. I did this. It installed without difficulty, and then I was able to install Eclipse without difficulty.

This took hours of my time. I hope this proves useful.

For the first ten multiples of 5, say

>>> [5*n for n in range(1,10+1)]
[5, 10, 15, 20, 25, 30, 35, 40, 45, 50]

Your code contains two problems:

• The equality operator in JavaScript is ==, not =.
• jQuery.text() joins all text nodes of matched elements into a single string. If you have two successive elements, of which the first contains 'some' and the second contains 'Text', then your code will incorrectly think that there exists an element that contains 'someText'.

I suggest the following instead:

if ($('#field > div.field-item:contains("someText")').length > 0) {
    $("#somediv").addClass("thisClass");
}

No, it's not possible.

Passing by reference implies that the function might change the value of the parameter. If the parameter is not provided by the caller and comes from the default constant, what is the function supposed to change?

Add a step attribute to the number input

Check out this example here http://codepen.io/LukeXF/pen/yOQWNb, you can use a simple function on page load and page resize to make the magic happen. Though be careful not lag out the client from too many function calls. (The example has a delay).

function resize() {  
    $('.resize').each(function(i, obj) {
        $(this).css('font-size', '8em');

        while ($(this).width() > $(this).parent().width()) {
            $(this).css('font-size', (parseInt($(this).css('font-size')) - 1) + "px");
        }
    });
}

The answers above were all assuming your Python distribution would have some third-party libraries in order to achieve the "one liner python ftpd" goal, but that is not the case of what @zio was asking. Also, SimpleHTTPServer involves web broswer for downloading files, it's not quick enough.

Python can't do ftpd by itself, but you can use netcat, nc:

nc is basically a built-in tool from any UNIX-like systems (even embedded systems), so it's perfect for "quick and temporary way to transfer files".

Step 1, on the receiver side, run:

nc -l 12345 | tar -xf -

this will listen on port 12345, waiting for data.

Step 2, on the sender side:

tar -cf - ALL_FILES_YOU_WANT_TO_SEND ... | nc $RECEIVER_IP 12345

You can also put pv in the middle to monitor the progress of transferring:

tar -cf - ALL_FILES_YOU_WANT_TO_SEND ...| pv | nc $RECEIVER_IP 12345

After the transferring is finished, both sides of nc will quit automatically, and job done.

You can try the following code:

import java.time.*;

public class Test{
   public static void main(String[] args) {
      DayOfWeek dow = LocalDate.of(2010,Month.FEBRUARY,23).getDayOfWeek();
      String s = String.valueOf(dow);
      System.out.println(String.format("%.3s",s));
   }
}

atoi can do that for you

Example:

char string[] = "1234";
int sum = atoi( string );
printf("Sum = %d\n", sum ); // Outputs: Sum = 1234

Match objects are always true, and None is returned if there is no match. Just test for trueness.

Code:

>>> st = 'bar'
>>> m = re.match(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
...
'bar'

Output = bar

If you want search functionality

>>> st = "bar"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m is not None:
...     m.group(0)
...
'bar'

and if regexp not found than

>>> st = "hello"
>>> m = re.search(r"ba[r|z|d]",st)
>>> if m:
...     m.group(0)
... else:
...   print "no match"
...
no match

As @bukzor mentioned if st = foo bar than match will not work. So, its more appropriate to use re.search.

This may help you find what you're looking for... Batch script loop

My answer is as follows:

@echo off
:start
set /a var+=1
if %var% EQU 100 goto end
:: Code you want to run goes here
goto start

:end
echo var has reached %var%.
pause
exit

The first set of commands under the start label loops until a variable, %var% reaches 100. Once this happens it will notify you and allow you to exit. This code can be adapted to your needs by changing the 100 to 17 and putting your code or using a call command followed by the batch file's path (Shift+Right Click on file and select "Copy as Path") where the comment is placed.

After changing the ID it android.R.id.custom, I needed to add the following to get the View to display:

((View) f1.getParent()).setVisibility(View.VISIBLE);

However, this caused the new View to render in a big parent view with no background, breaking the dialog box in two parts (text and buttons, with the new View in between). I finally got the effect that I wanted by inserting my View next to the message:

LinearLayout f1 = (LinearLayout)findViewById(android.R.id.message).getParent().getParent();

I found this solution by exploring the View tree with View.getParent() and View.getChildAt(int). Not really happy about either, though. None of this is in the Android docs and if they ever change the structure of the AlertDialog, this might break.

Pointers are important in many data structures whose design requires the ability to link or chain one "node" to another efficiently. You would not "choose" a pointer over say a normal data type like float, they simply have different purposes.

Pointers are useful where you require high performance and/or compact memory footprint.

The address of the first element in your array can be assigned to a pointer. This then allows you to access the underlying allocated bytes directly. The whole point of an array is to avoid you needing to do this though.

For Jenkins 2.190.1 this works for sure:

    post {
        always {
            cleanWs deleteDirs: true, notFailBuild: true
        }
    }

You dont actually need the @Query annotation at all.

You can just use the following

    @Repository("registerUserRepository")
    public interface RegisterUserRepository extends JpaRepository<Registration,Long>{
    
    List<Registration> findByPlaceIgnoreCaseContaining(String place);

    }

  scanf ("%c", &alphabet);
  printf("ASCII value of '%c' is %d", alphabet, (char)alphabet );
}

I would use BeginInvoke instead of Invoke as often as possible, unless you are really required to wait until your control has been updated (which in your example is not the case). BeginInvoke posts the delegate on the WinForms message queue and lets the calling code proceed immediately (in your case the for-loop in the SampleFunction). Invoke not only posts the delegate, but also waits until it has been completed.

So in the method AppendTextBox from your example you would replace Invoke with BeginInvoke like that:

public void AppendTextBox(string value)
{
    if (InvokeRequired)
    {
        this.BeginInvoke(new Action<string>(AppendTextBox), new object[] {value});
        return;
    }
    textBox1.Text += value;
}

Well and if you want to get even more fancy, there is also the SynchronizationContext class, which lets you basically do the same as Control.Invoke/Control.BeginInvoke, but with the advantage of not needing a WinForms control reference to be known. Here is a small tutorial on SynchronizationContext.

I'd rather this simple solution:

String content = "Thequickbrownfoxjumps";
while(content.length() > 4) {
    System.out.println(content.substring(0, 4));
    content = content.substring(4);
}
System.out.println(content);

How about this (in you don't want an one liner) ?

for row in df.collect():
    d = row.asDict()
    s = "%d\t%s\t%s\n" % (d["int_column"], d["string_column"], d["string_column"])
    f.write(s)

f is a opened file descriptor. Also the separator is a TAB char, but it's easy to change to whatever you want.

Wouldn't you just change:

numero = stmt.executeUpdate(query);

to:

numero = stmt.executeUpdate(query, Statement.RETURN_GENERATED_KEYS);

Take a look at the documentation for the JDBC Statement interface.

Update: Apparently there is a lot of confusion about this answer, but my guess is that the people that are confused are not reading it in the context of the question that was asked. If you take the code that the OP provided in his question and replace the single line (line 6) that I am suggesting, everything will work. The numero variable is completely irrelevant and its value is never read after it is set.

If you change the format of the cells to General then this will show the date value of a cell as behind the scenes Excel saves a date as the number of days since 01/01/1900

If your date is text and you need to convert it then DATEVALUE will do this:

Here is a special case that might be good enough:

 [ (1.0/divStep)*x for x in range(start*divStep, stop*divStep)]

In your case this would be:

#for(float x = 0; x < 10; x += 0.5f) { /* ... */ } ==>
start = 0
stop  = 10
divstep = 1/.5 = 2 #This needs to be int, thats why I said 'special case'

and so:

>>> [ .5*x for x in range(0*2, 10*2)]
[0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, 9.5]

Python >= 3.5 alternative: unpack into a list literal [*newdict]

New unpacking generalizations (PEP 448) were introduced with Python 3.5 allowing you to now easily do:

>>> newdict = {1:0, 2:0, 3:0}
>>> [*newdict]
[1, 2, 3]

Unpacking with * works with any object that is iterable and, since dictionaries return their keys when iterated through, you can easily create a list by using it within a list literal.

Adding .keys() i.e [*newdict.keys()] might help in making your intent a bit more explicit though it will cost you a function look-up and invocation. (which, in all honesty, isn't something you should really be worried about).

_{The *iterable syntax is similar to doing list(iterable) and its behaviour was initially documented in the Calls section of the Python Reference manual. With PEP 448 the restriction on where *iterable could appear was loosened allowing it to also be placed in list, set and tuple literals, the reference manual on Expression lists was also updated to state this.}

Though equivalent to list(newdict) with the difference that it's faster (at least for small dictionaries) because no function call is actually performed:

%timeit [*newdict]
1000000 loops, best of 3: 249 ns per loop

%timeit list(newdict)
1000000 loops, best of 3: 508 ns per loop

%timeit [k for k in newdict]
1000000 loops, best of 3: 574 ns per loop

with larger dictionaries the speed is pretty much the same (the overhead of iterating through a large collection trumps the small cost of a function call).

In a similar fashion, you can create tuples and sets of dictionary keys:

>>> *newdict,
(1, 2, 3)
>>> {*newdict}
{1, 2, 3}

beware of the trailing comma in the tuple case!

That is the textarea's job - for multiline text input. The input won't do it; it wasn't designed to do it.

So use a textarea. Besides their visual differences, they are accessed via JavaScript the same way (use value property).

You can prevent newlines being entered via the input event and simply using a replace(/\n/g, '').

Here is the JSFiddle Demo. In Google Maps API V3 it's pretty simple to track the lat and lng of a draggable marker. Let's start with the following HTML and CSS as our base.

<div id='map_canvas'></div>
<div id="current">Nothing yet...</div>

#map_canvas{
    width: 400px;
    height: 300px;
}

#current{
     padding-top: 25px;
}

Here is our initial JavaScript initializing the google map. We create a marker that we want to drag and set it's draggable property to true. Of course keep in mind it should be attached to an onload event of your window for it to be loaded, but i'll skip to the code:

var map = new google.maps.Map(document.getElementById('map_canvas'), {
    zoom: 1,
    center: new google.maps.LatLng(35.137879, -82.836914),
    mapTypeId: google.maps.MapTypeId.ROADMAP
});

var myMarker = new google.maps.Marker({
    position: new google.maps.LatLng(47.651968, 9.478485),
    draggable: true
});

Here we attach two events dragstart to track the start of dragging and dragend to drack when the marker stop getting dragged, and the way we attach it is to use google.maps.event.addListener. What we are doing here is setting the div current's content when marker is getting dragged and then set the marker's lat and lng when drag stops. Google mouse event has a property name 'latlng' that returns 'google.maps.LatLng' object when the event triggers. So, what we are doing here is basically using the identifier for this listener that gets returned by the google.maps.event.addListener and get the property latLng to extract the dragend's current position. Once we get that Lat Lng when the drag stops we'll display within your current div:

google.maps.event.addListener(myMarker, 'dragend', function(evt){
    document.getElementById('current').innerHTML = '<p>Marker dropped: Current Lat: ' + evt.latLng.lat().toFixed(3) + ' Current Lng: ' + evt.latLng.lng().toFixed(3) + '</p>';
});

google.maps.event.addListener(myMarker, 'dragstart', function(evt){
    document.getElementById('current').innerHTML = '<p>Currently dragging marker...</p>';
});

Lastly, we'll center our marker and display it on the map:

map.setCenter(myMarker.position);
myMarker.setMap(map);

Let me know if you have any questions regarding my answer.

What you're doing is valid for the current session (limited to the terminal that you're working in). You need to persist those changes. Consider adding commands in steps 1-3 above to your ${HOME}/.bashrc.

I have been seeing the exact same error today, but it was not a config or direct JavaScript issue.

An external .net project had been updated but the changes not picked up properly in the compilation of the web site. My presumption is that ASP.NET ajax was not able to construct the client representations of the .NET objects properly and so was failing to load correctly.

To resolve, I rebuilt the external project(s), and rebuilt my solution that was experiencing issues. The problem went away.

It's an extension for the User Controls you have in your project.

A user control is a kind of composite control that works much like an ASP.NET Web page—you can add existing Web server controls and markup to a user control, and define properties and methods for the control. You can then embed them in ASP.NET Web pages, where they act as a unit.

Simply, if you want to have some functionality that will be used on many pages in your project then you should create a User control or Composite control and use it in your pages. It just helps you to keep the same functionality and code in one place. And it makes it reusable.

You can simply use $_GET especially if you know the othervar's name. If you want to be on the safe side, use if (isset ($_GET ['varname'])) to test for existence.

Also if you want selected field from table and aggregated then as array .

SELECT json_agg(json_build_object('data_a',a,
                                  'data_b',b,
))  from t;

The result will come .

 [{'data_a':1,'data_b':'value1'}
  {'data_a':2,'data_b':'value2'}]

Well there's the Network Connections preference page; you can add proxies there. I don't know much about it; I don't know if the Maven integration plugins will use the proxies defined there.

You can find it at Window...Preferences, then General...Network Connections.

They both seems to navigate to the given webpage and quoting @matt answer:

navigate().to() and get() do exactly the same thing.

Single-Page Applications are an exception to this.

The difference between these two methods comes not from their behavior, but from the behavior in the way the application works and how browser deal with it.

navigate().to() navigates to the page by changing the URL like doing forward/backward navigation.

Whereas, get() refreshes the page to changing the URL.

So, in cases where application domain changes, both the method behaves similarly. That is, page is refreshed in both the cases. But, in single-page applications, while navigate().to() do not refreshes the page, get() do.

Moreover, this is the reason browser history is getting lost when get() is used due to application being refreshed.

Originally answered: https://stackoverflow.com/a/33868976/3619412

complete executes after either the success or error callback were executed.

Maybe you should check the second parameter complete offers too. It's a String holding the type of success the ajaxCall had.

The different callbacks are described a little more in detail here jQuery.ajax( options )

I guess you missed the fact that the complete and the success function (I know inconsistent API) get different data passed in. success gets only the data, complete gets the whole XMLHttpRequest object. Of course there is no responseText property on the data string.

So if you replace complete with success you also have to replace data.responseText with data only.

success

The function gets passed two arguments: The data returned from the server, formatted according to the 'dataType' parameter, and a string describing the status.

complete

The function gets passed two arguments: The XMLHttpRequest object and a string describing the type of success of the request.

If you need to have access to the whole XMLHttpRequest object in the success callback I suggest trying this.

var myXHR = $.ajax({
    ...
    success: function(data, status) {
        ...do whatever with myXHR; e.g. myXHR.responseText...
    },
    ...
});

In Python, you'd do this with a default argument.

class A:

    def stackoverflow(self, i=None):    
        if i == None:
            print 'first method'
        else:
            print 'second method',i

Rename your file, commit the changes including the "deleted" file, and don't include the new (renamed) file.

Rename your file back.

In the absence of the ability to do zone transfers, I wrote this small bash script, dg:

#!/bin/bash
COMMON_SUBDOMAINS=(www mail smtp pop imap blog en ftp ssh login)
if [[ "$2" == "x" ]]; then
    dig +nocmd "$1" +noall +answer "${3:-any}"
    wild_ips="$(dig +short "*.$1" "${3:-any}" | tr '\n' '|')"
    wild_ips="${wild_ips%|}"
    for sub in "${COMMON_SUBDOMAINS[@]}"; do
        dig +nocmd "$sub.$1" +noall +answer "${3:-any}"
    done | grep -vE "${wild_ips}"
    dig +nocmd "*.$1" +noall +answer "${3:-any}"
else
    dig +nocmd "$1" +noall +answer "${2:-any}"
fi

Now I use dg example.com to get a nice, clean list of DNS records, or dg example.com x to include a bunch of other popular subdomains.

grep -vE "${wild_ips}" filters out records that could be the result of a wildcard DNS entry such as * 10800 IN A 1.38.216.82. Otherwise, a wildcard entry would make it appear as if there were records for each $COMMON_SUBDOMAN.

Note: This relies on ANY queries, which are blocked by some DNS providers such as CloudFlare.

First Method

when you want to open a video in full screen for that Activity you have to set the theme attribute in the Manifest. set this value that is

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

change theme programmatically here

Second Method

create another fullscreen.xml like below and setContentView(R.layout.fullscreen) on click of the button

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <VideoView android:id="@+id/myvideoview"
        android:layout_width="fill_parent"
        android:layout_alignParentRight="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_alignParentBottom="true"
        android:layout_height="fill_parent">
    </VideoView>

</RelativeLayout>

Add this for pages not currently on your site...

ErrorDocument 404 http://example.com/

Along with your Redirect 301 / http://www.thenewdomain.com/ that should cover all the bases...

Good luck!

Update

With ES6, this is possible in exactly the manner you have described; a detailed description can be found in the documentation.

Old answer

Default parameters in JavaScript can be implemented in mainly two ways:

function myfunc(a, b)
{
    // use this if you specifically want to know if b was passed
    if (b === undefined) {
        // b was not passed
    }
    // use this if you know that a truthy value comparison will be enough
    if (b) {
        // b was passed and has truthy value
    } else {
        // b was not passed or has falsy value
    }
    // use this to set b to a default value (using truthy comparison)
    b = b || "default value";
}

The expression b || "default value" evaluates the value AND existence of b and returns the value of "default value" if b either doesn't exist or is falsy.

Alternative declaration:

function myfunc(a)
{
    var b;

    // use this to determine whether b was passed or not
    if (arguments.length == 1) {
        // b was not passed
    } else {
        b = arguments[1]; // take second argument
    }
}

The special "array" arguments is available inside the function; it contains all the arguments, starting from index 0 to N - 1 (where N is the number of arguments passed).

This is typically used to support an unknown number of optional parameters (of the same type); however, stating the expected arguments is preferred!

Further considerations

Although undefined is not writable since ES5, some browsers are known to not enforce this. There are two alternatives you could use if you're worried about this:

b === void 0;
typeof b === 'undefined'; // also works for undeclared variables

I only needed the environment variables locally to invoke my test command, here's an example setting multiple environment vars in a bash shell, and escaping the dollar sign in make.

SHELL := /bin/bash

.PHONY: test tests
test tests:
    PATH=./node_modules/.bin/:$$PATH \
    JSCOVERAGE=1 \
    nodeunit tests/

In my case, I add file as Link from another project and then rename file in source project that cause problem in destination project. I delete linked file in destination and add again with new name.

1)Go to configure build path . 2)Remove unbound JRE library . 3)Add library --> JRE System library .

Then project compile and done ..

There is no Pair in the standard framework, but the Apache Commons Lang, which comes quite close to “standard”, has a Pair.

Don't forget to use var/let while declaring any variable.See below examples for JS compiler behaviour.

function  func(){
return true;
}

isBool = func();
console.log(typeof (isBool));   // output - string


let isBool = func();
console.log(typeof (isBool));   // output - boolean

If your $VARIABLE is a string containing spaces or other special characters, and single square brackets are used (which is a shortcut for the test command), then the string may be split out into multiple words. Each of these is treated as a separate argument.

So that one variable is split out into many arguments:

VARIABLE=$(/some/command);  
# returns "hello world"

if [ $VARIABLE == 0 ]; then
  # fails as if you wrote:
  # if [ hello world == 0 ]
fi 

The same will be true for any function call that puts down a string containing spaces or other special characters.

Easy fix

Wrap the variable output in double quotes, forcing it to stay as one string (therefore one argument). For example,

VARIABLE=$(/some/command);
if [ "$VARIABLE" == 0 ]; then
  # some action
fi 

Simple as that. But skip to "Also beware..." below if you also can't guarantee your variable won't be an empty string, or a string that contains nothing but whitespace.

Or, an alternate fix is to use double square brackets (which is a shortcut for the new test command).

This exists only in bash (and apparently korn and zsh) however, and so may not be compatible with default shells called by /bin/sh etc.

This means on some systems, it might work from the console but not when called elsewhere, like from cron, depending on how everything is configured.

It would look like this:

VARIABLE=$(/some/command);
if [[ $VARIABLE == 0 ]]; then
  # some action
fi 

If your command contains double square brackets like this and you get errors in logs but it works from the console, try swapping out the [[ for an alternative suggested here, or, ensure that whatever runs your script uses a shell that supports [[ aka new test.

Also beware of the [: unary operator expected error

If you're seeing the "too many arguments" error, chances are you're getting a string from a function with unpredictable output. If it's also possible to get an empty string (or all whitespace string), this would be treated as zero arguments even with the above "quick fix", and would fail with [: unary operator expected

It's the same 'gotcha' if you're used to other languages - you don't expect the contents of a variable to be effectively printed into the code like this before it is evaluated.

Here's an example that prevents both the [: too many arguments and the [: unary operator expected errors: replacing the output with a default value if it is empty (in this example, 0), with double quotes wrapped around the whole thing:

VARIABLE=$(/some/command);
if [ "${VARIABLE:-0}" == 0 ]; then
  # some action
fi 

(here, the action will happen if $VARIABLE is 0, or empty. Naturally, you should change the 0 (the default value) to a different default value if different behaviour is wanted)

Final note: Since [ is a shortcut for test, all the above is also true for the error test: too many arguments (and also test: unary operator expected)

If you just want to display it when you get a response add this to your loadpage()

function loadpage(page_request, containerid){
   if (page_request.readyState == 4 && page_request.status==200) { 
      var container = document.getElementById(containerid);
      container.innerHTML=page_request.responseText;
      container.style.visibility = 'visible';
      // or 
      container.style.display = 'block';
}

but this depend entirely on how you hid the div in the first place

You have the button tag

http://www.w3schools.com/tags/tag_button.asp

<button>What ever you want</button>

Instead of having to specify a locale in all parses, I prefer to set an application wide locale, although if string formats are not consistent across the app, this might not work.

CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("pt-PT");
CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("pt-PT");

Defining this at the begining of your application will make all double parses expect a comma as the decimal delimiter. You can set an appropriate locale so that the decimal and thousands separator fits the strings you are parsing.

The book seems to be "C++ for Engineers and Scientists" written by Gary Bronson (googled it).
Is this a possible answer? IMHO it's surprising.

I had to read the question (from the book) a few times. My interpretation:
For each number N: 2 <= N < 100 check whether it's prime.
How? For each divisor D: 2 <= D < sqrt(N) ,
if D divides N, N is not prime, if D > sqrt(N), N is prime.

Give it a try:

N = 2, sqrt(2) ˜ 1.41, D = 2, 2 < 1.41 ?  no 2 > 1.41 ? yes 2 is prime.  
N = 3, sqrt(3) ˜ 1.73, D = 2, 2 < 1.73 ?  no 2 > 1.73 ? yes 3 is prime.  
N = 4, sqrt(4) = 2.00, D = 2, 2 < 2.00 ?  no 2 > 2.00 ?  no 4 is not prime.  
N = 5, sqrt(5) ˜ 2.24, D = 2, 2 < 2.24 ? yes 5 % 2 > 0? yes  
                       D = 3, 3 < 2.24 ?  no 3 > 2.24 ? yes 5 is prime.    
N = 6, sqrt(6) ˜ 2.45, D = 2, 2 < 2.45 ? yes 6 % 2 = 0  2 > 2.45 ? no 6 is not prime.

As far as I can see, that's how the primes should be found,
not with a sieve (much, much faster),
but with: the answer is in the question! Surprising?

Speed? primes < 400,000 : less than 10 seconds (on my watch, a rolex, I bought it on the market, the seller said it was a real one, a real one for the price of two baguettes, with 12 real diamonds as well).
Let's count the primes (I'm not going to show code ;) : 664579 primes < 10,000,000 : 5 seconds.

#include "stdafx.h"
#include <math.h>
#include <iostream>
using namespace std;
int main()
{
    double rt;
    for (int d = 2, n = 2; n < 100; d = 2, n++)
    {
        for (rt = sqrt(n); d < rt; d++)
            if (n % d == 0) break;
        if (d > rt) cout << n << " ";
    }
    getchar();  // 25 primes :-)
}

Deleted an earlier answer with (like other answers) a prime-sieve.
Hopefully I get my next "Necromancer" badge soon.

I asked the author: In your book: "C++ for E&S" is an exercise about prime numbers,[xrcs]...[/xrcs]. Seven years ago it was asked at: SO/q/5200879
A few days ago I gave an answer: SO/a/49199435
Do you think it is a reasonable solution, or perhaps the solution.

He replied: Peter, I never really have a specific solution in mind when I am making up the exercises,
so I can’t say I had your exact solution in mind. The joy of C++ is that one can come up with really creative solutions and great code, as, on first glance, it looks like you have done.
Thanks for sending it!

PS. A sieve: https://pastebin.com/JMdTxbeJ

I just came across this problem when I replaced a failing disk. I had copied over the system files to the new disk, and was good about replacing the old disk's UUID entry with the new disk's UUID in fstab.

However I had not replaced the UUID in the grub.conf (sometimes menu.lst) file in /boot/grub. So check your grub.conf file, and if the "kernel" line has something like

kernel ... root=UUID=906eaa97-f66a-4d39-a39d-5091c7095987 

it likely has the old disk's UUID. Replace it with the new disk's UUID and run grub-install (if you're in a live CD rescue you may need to chroot or specify the grub directory).

Syntax is source <file-name>

ex. source config.sh

script - config.sh

USERNAME="satish"
EMAIL="[email protected]"

calling script -

#!/bin/bash
source config.sh
echo Welcome ${USERNAME}!
echo Your email is ${EMAIL}.

You can learn to include a bash script in another bash script here.

This is in slight response to Joel's comment about making a slighly more optimized version. Instead of returning a random date directly, why not return a generator function which can be called repeatedly to create a random date.

Func<DateTime> RandomDayFunc()
{
    DateTime start = new DateTime(1995, 1, 1); 
    Random gen = new Random(); 
    int range = ((TimeSpan)(DateTime.Today - start)).Days; 
    return () => start.AddDays(gen.Next(range));
}

Also could be like this

df.filter(col('bar').isin(['a','b']) == False).show()

Short answer

Why? Because there is still whitespace (carriage returns, tabs, spaces, newline) left in the input stream.

When? When you are using some function which does not on their own ignores the leading whitespaces. Cin by default ignores and removes the leading whitespace but getline does not ignore the leading whitespace on its own.

Now a detailed answer.

Everything you input in the console is read from the standard stream stdin. When you enter something, let's say 256 in your case and press enter, the contents of the stream become 256\n. Now cin picks up 256 and removes it from the stream and \n still remaining in the stream. Now next when you enter your name, let's say Raddicus, the new contents of the stream is \nRaddicus.

Now here comes the catch. When you try to read a line using getline, if not provided any delimiter as the third argument, getline by default reads till the newline character and removes the newline character from the stream. So on calling new line, getline reads and discards \n from the stream and resulting in an empty string read in mystr which appears like getline is skipped (but it's not) because there was already an newline in the stream, getline will not prompt for input as it has already read what it was supposed to read.

Now, how does cin.ignore help here?

According to the ignore documentation extract from cplusplus.com-

istream& ignore (streamsize n = 1, int delim = EOF);

Extracts characters from the input sequence and discards them, until either n characters have been extracted, or one compares equal to delim.

The function also stops extracting characters if the end-of-file is reached. If this is reached prematurely (before either extracting n characters or finding delim), the function sets the eofbit flag.

So, cin.ignore(256, '\n');, ignores first 256 characters or all the character untill it encounters delimeter (here \n in your case), whichever comes first (here \n is the first character, so it ignores until \n is encountered).

Just for your reference, If you don't exactly know how many characters to skip and your sole purpose is to clear the stream to prepare for reading a string using getline or cin you should use cin.ignore(numeric_limits<streamsize>::max(),'\n').

Quick explanation: It ignores the characters equal to maximum size of stream or until a '\n' is encountered, whichever case happens first.

This is also one of the example for anonymous inner type using thread

AFAIK you cannot use VBA Excel to create custom tab in the Excel ribbon. You can however hide/make visible a ribbon component using VBA. Additionally, the link that you mentioned above is for MS Project and not MS Excel.

I create tabs for my Excel Applications/Add-Ins using this free utility called Custom UI Editor.

Edit: To accommodate new request by OP

Tutorial

Here is a short tutorial as promised:

1. After you have installed the Custom UI Editor (CUIE), open it and then click on File | Open and select the relevant Excel File. Please ensure that the Excel File is closed before you open it via CUIE. I am using a brand new worksheet as an example.

   

2. Right click as shown in the image below and click on "Office 2007 Custom UI Part". It will insert the "customUI.xml"

   

3. Next Click on menu Insert | Sample XML | Custom Tab. You will notice that the basic code is automatically generated. Now you are all set to edit it as per your requirements.

   

4. Let's inspect the code

   

   label="Custom Tab": Replace "Custom Tab" with the name which you want to give your tab. For the time being let's call it "Jerome".

   The below part adds a custom button.

   <button id="customButton" label="Custom Button" imageMso="HappyFace" size="large" onAction="Callback" />
   

   imageMso: This is the image that will display on the button. "HappyFace" is what you will see at the moment. You can download more image ID's here.

   onAction="Callback": "Callback" is the name of the procedure which runs when you click on the button.

Demo

With that, let's create 2 buttons and call them "JG Button 1" and "JG Button 2". Let's keep happy face as the image of the first one and let's keep the "Sun" for the second. The amended code now looks like this:

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui">
<ribbon startFromScratch="false">
<tabs>
<tab id="MyCustomTab" label="Jerome" insertAfterMso="TabView">
<group id="customGroup1" label="First Tab">
<button id="customButton1" label="JG Button 1" imageMso="HappyFace" size="large" onAction="Callback1" />
<button id="customButton2" label="JG Button 2" imageMso="PictureBrightnessGallery" size="large" onAction="Callback2" />
</group>
</tab>
</tabs>
</ribbon>
</customUI>

Delete all the code which was generated in CUIE and then paste the above code in lieu of that. Save and close CUIE. Now when you open the Excel File it will look like this:

Now the code part. Open VBA Editor, insert a module, and paste this code:

Public Sub Callback1(control As IRibbonControl)

    MsgBox "You pressed Happy Face"

End Sub

Public Sub Callback2(control As IRibbonControl)

    MsgBox "You pressed the Sun"

End Sub

Save the Excel file as a macro enabled file. Now when you click on the Smiley or the Sun you will see the relevant message box:

Hope this helps!

You simply combine the ideas of a link to another page, as with href=foo.html, and a link to an element on the same page, as with href=#bar, so that the fragment like #bar is written immediately after the URL that refers to another page:

<a href="foo.html#bar">Some nice link text</a>

The target is specified the same was as when linking inside one page, e.g.

<div id="bar">
<h2>Some heading</h2>
Some content
</div>

or (if you really want to link specifically to a heading only)

<h2 id="bar">Some heading</h2>

In the .service file under the [Unit] section:

[Unit]
Description=My Website
After=syslog.target network.target mongodb.service

The important part is the mongodb.service

The manpage describes it however due to formatting it's not as clear on first sight

systemd.unit - well formatted

systemd.unit - not so well formatted

A python-like solution, which allows you to use negative index,

var str = "Hello world!"
str[-1]        // "!"

could be:

extension String {
    subscript (var index:Int)->Character{
        get {
            let n = distance(self.startIndex, self.endIndex)
            index %= n
            if index < 0 { index += n }
            return self[advance(startIndex, index)]
        }
    }
}

By the way, it may be worth it to transpose the whole python's slice notation

The best way to do this these day is to use the 'requests' library:

import requests
response = requests.get('http://hiscore.runescape.com/index_lite.ws?player=zezima')
print (response.status_code)
print (response.content)

Can't change the default browser, but try this (found online a while ago). Add a bookmark in Safari called "Open in Chrome" with the following.

javascript:location.href=%22googlechrome%22+location.href.substring(4);

Will open the current page in Chrome. Not as convenient, but maybe someone will find it useful.

Works for me.

I think you are looking for JAX-WS authentication in application level, not HTTP basic in server level. See following complete example :

Application Authentication with JAX-WS

On the web service client site, just put your “username” and “password” into request header.

Map<String, Object> req_ctx = ((BindingProvider)port).getRequestContext();
req_ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, WS_URL);

Map<String, List<String>> headers = new HashMap<String, List<String>>();
headers.put("Username", Collections.singletonList("someUser"));
headers.put("Password", Collections.singletonList("somePass"));
req_ctx.put(MessageContext.HTTP_REQUEST_HEADERS, headers);

On the web service server site, get the request header parameters via WebServiceContext.

@Resource
WebServiceContext wsctx;

@WebMethod
public String method() {
    MessageContext mctx = wsctx.getMessageContext();

    Map http_headers = (Map) mctx.get(MessageContext.HTTP_REQUEST_HEADERS);
    List userList = (List) http_headers.get("Username");
    List passList = (List) http_headers.get("Password");
    //...

I ran into the same problem today but the solution of @Mark-Nutter was incomplete to remove the hashbang from my angularjs application.

In fact you have to go to Edit Permissions, click on Add more permissions and then add the right List on your bucket to everyone. With this configuration, AWS S3 will now, be able to return 404 error and then the redirection rule will properly catch the case.

Just like this :

And then you can go to Edit Redirection Rules and add this rule :

<RoutingRules>
    <RoutingRule>
        <Condition>
            <HttpErrorCodeReturnedEquals>404</HttpErrorCodeReturnedEquals>
        </Condition>
        <Redirect>
            <HostName>subdomain.domain.fr</HostName>
            <ReplaceKeyPrefixWith>#!/</ReplaceKeyPrefixWith>
        </Redirect>
    </RoutingRule>
</RoutingRules>

Here you can replace the HostName subdomain.domain.fr with your domain and the KeyPrefix #!/ if you don't use the hashbang method for SEO purpose.

Of course, all of this will only work if you have already have setup html5mode in your angular application.

$locationProvider.html5Mode(true).hashPrefix('!');

Just use npm module config (more than 300000 downloads)

https://www.npmjs.com/package/config

Node-config organizes hierarchical configurations for your app deployments.

It lets you define a set of default parameters, and extend them for different deployment environments (development, qa, staging, production, etc.).

$ npm install config
$ mkdir config
$ vi config/default.json


{
      // Customer module configs
      "Customer": {
        "dbConfig": {
          "host": "localhost",
          "port": 5984,
          "dbName": "customers"
        },
        "credit": {
          "initialLimit": 100,
          // Set low for development
          "initialDays": 1
        }
      }
}



$ vi config/production.json

{
  "Customer": {
    "dbConfig": {
      "host": "prod-db-server"
    },
    "credit": {
      "initialDays": 30
    }
  }
}



$ vi index.js

var config = require('config');
//...
var dbConfig = config.get('Customer.dbConfig');
db.connect(dbConfig, ...);

if (config.has('optionalFeature.detail')) {
  var detail = config.get('optionalFeature.detail');
  //...
}


$ export NODE_ENV=production
$ node index.js

You can use

    CameraUpdate center = CameraUpdateFactory.newLatLng(new LatLng(location.getLatitude(), location.getLongitude()));
    CameraUpdate zoom = CameraUpdateFactory.zoomTo(12);

I found that the example I was using had an xml document specification on the first line. I was using a stylesheet I got at this blog entry and the first line was

<?xmlversion="1.0"encoding="utf-8"?>

which was causing the error. When I removed that line, so that the stylesheet started with the line

<xsl:stylesheet version="1.0" xmlns:DTS="www.microsoft.com/SqlServer/Dts" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

my transform worked. By the way, that blog post was the first good, easy-to follow example I have found for trying to get information from the XML definition of an SSIS package, but I did have to modify the paths in the example for my SSIS 2008 packages, so you might too. I also created a version to extract the "flow" from the precedence constraints. My final one looks like this:

    <xsl:stylesheet version="1.0" xmlns:DTS="www.microsoft.com/SqlServer/Dts" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="text" encoding="utf-8" />
    <xsl:template match="/">
    <xsl:text>From,To~</xsl:text>
    <xsl:text>
</xsl:text>
    <xsl:for-each select="//DTS:PrecedenceConstraints/DTS:PrecedenceConstraint">
      <xsl:value-of select="@DTS:From"/>
      <xsl:text>,</xsl:text>
      <xsl:value-of select="@DTS:To"/>
       <xsl:text>~</xsl:text>
      <xsl:text>
</xsl:text>
    </xsl:for-each>
    </xsl:template>
</xsl:stylesheet>

and gave me a CSV with the tilde as my line delimiter. I replaced that with a line feed in my text editor then imported into excel to get a with look at the data flow in the package.

The li tag has a property called list-style-position. This makes your bullets inside or outside the list. On default, it’s set to inside. That makes your text wrap around it. If you set it to outside, the text of your li tags will be aligned.

The downside of that is that your bullets won't be aligned with the text outside the ul. If you want to align it with the other text you can use a margin.

ul li {
    /*
     * We want the bullets outside of the list,
     * so the text is aligned. Now the actual bullet
     * is outside of the list’s container
     */
    list-style-position: outside;

    /*
     * Because the bullet is outside of the list’s
     * container, indent the list entirely
     */
    margin-left: 1em;
}

Edit 15th of March, 2014 Seeing people are still coming in from Google, I felt like the original answer could use some improvement

• Changed the code block to provide just the solution
• Changed the indentation unit to em’s
• Each property is applied to the ul element
• Good comments :)

Couldn't you just have another sub that acts as a caller using module level variable(s) for the arguments you want to pass. For example...

Option Explicit
Public strMsg As String

Sub Scheduler()

    strMsg = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
    Application.OnTime Now + TimeValue("00:00:01"), "'Caller'"

End Sub

Sub Caller()

    Call aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa("It Works! " & strMsg)

End Sub

Sub aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa(strMessage As String)

    MsgBox strMessage

End Sub

Use this code.

class PlayerPreferences extends StatefulWidget {
  final int numPlayers;
  PlayerPreferences({this.numPlayers});

  @override
  _PlayerPreferencesState createState() => _PlayerPreferencesState();
}

class _PlayerPreferencesState extends State<PlayerPreferences> {
  int dropDownValue = 0;
  @override
  Widget build(BuildContext context) {
    return Container(
      child: DropdownButton(
        value: dropDownValue,
        onChanged: (int newVal){
          setState(() {
            dropDownValue = newVal;
          });
        },
        items: [
          DropdownMenuItem(
            value: 0,
            child: Text('Yellow'),
          ),
          DropdownMenuItem(
            value: 1,
            child: Text('Red'),
          ),
          DropdownMenuItem(
            value: 2,
            child: Text('Blue'),
          ),
          DropdownMenuItem(
            value: 3,
            child: Text('Green'),
          ),
        ],
      ),
    );
  }
}

and in the main body we call as

class ModeSelection extends StatelessWidget{
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: Container(
          child: PlayerPreferences(),
        ) ,
      ),
    );
  }
}

It depends what is the character and what encoding it is in:

• An ASCII character in 8-bit ASCII encoding is 8 bits (1 byte), though it can fit in 7 bits.

• An ISO-8895-1 character in ISO-8859-1 encoding is 8 bits (1 byte).

• A Unicode character in UTF-8 encoding is between 8 bits (1 byte) and 32 bits (4 bytes).

• A Unicode character in UTF-16 encoding is between 16 (2 bytes) and 32 bits (4 bytes), though most of the common characters take 16 bits. This is the encoding used by Windows internally.

• A Unicode character in UTF-32 encoding is always 32 bits (4 bytes).

• An ASCII character in UTF-8 is 8 bits (1 byte), and in UTF-16 - 16 bits.

• The additional (non-ASCII) characters in ISO-8895-1 (0xA0-0xFF) would take 16 bits in UTF-8 and UTF-16.

That would mean that there are between 0.03125 and 0.125 characters in a bit.
